<p>Currently in day 15 of Angela's 100 days of python. What I understood from all the exercises and project is that variables outside the function cannot be used inside a function unless it is passed as an argument or you input "global" inside the function.</p>
<pre><code>MENU = {
"espresso": {
"ingredients": {
"water": 50,
"coffee": 18,
},
"cost": 1.5,
},
"latte": {
"ingredients": {
"water": 200,
"milk": 150,
"coffee": 24,
},
"cost": 2.5,
},
"cappuccino": {
"ingredients": {
"water": 250,
"milk": 100,
"coffee": 24,
},
"cost": 3.0,
}
}
profit = 0
resources = {
"water": 300,
"milk": 200,
"coffee": 100,
}
def is_resource_sufficient(order_ingredients):
"""Returns True when order can be made, False if ingredients are insufficient."""
for item in order_ingredients:
if order_ingredients[item] > resources[item]:
print(f"Sorry there is not enough {item}.")
return False
return True

"""Returns the total calculated from coins inserted."""
print("Please insert coins.")
total = int(input("how many quarters?: ")) * 0.25
total += int(input("how many dimes?: ")) * 0.1
total += int(input("how many nickles?: ")) * 0.05
total += int(input("how many pennies?: ")) * 0.01
return total
def is_transaction_successful(money_received, drink_cost):
"""Return True when the payment is accepted, or False if money is insufficient."""
if money_received >= drink_cost:
change = round(money_received - drink_cost, 2)
print(f"Here is ${change} in change.")
global profit

return True
else:
print("Sorry that's not enough money. Money refunded.")
return False
def make_coffee(drink_name, order_ingredients):

<p>I tried to look at her solution and saw that one of her function is using the dictionary resources that is not declared inside the function nor passed as an argument. I am not very good in english that's why I am having a hard time searching in the internet what I specifically want to understand. Can someone enlighten me with this topic please.</p>
<p>NOTE: it is not advised to use global</p>
<p>My code:</p>
<p>(my understanding is that you can never use variables outside the function if it is not either set to global or passed as an argument)</p>
<pre><code>def use_resources(user_order, machine_menu, machine_resources):
"""Deduct the resources needed for the user's order and returns the current resources of the machine after the
user's order. """
for menu_ingredients_key in machine_menu[user_order]["ingredients"]:
# print(menu_ingredients_key) # REPRESENT KEY water, coffee
# print(menu[order]["ingredients"][menu_ingredients_key]) # REPRESENT VALUES [50,18]
for resources_key in machine_resources:
if resources_key == menu_ingredients_key:
machine_resources[menu_ingredients_key] -= menu[user_order]["ingredients"][menu_ingredients_key]
print(f"Here is your {user_order} ☕. Enjoy! Come again :)")
</code></pre>
<p>How can the function use the resources that was declared outside the function and not passed as an argument?</p>
<pre><code>def make_coffee(drink_name, order_ingredients):
"""Deduct the required ingredients from the resources."""
for item in order_ingredients:
resources[item] -= order_ingredients[item]
print(f"Here is your {drink_name} ☕️. Enjoy!")

<p>What is the correct way to represent this structure in JSON<br />
Its Array of strings, with identifiers (A is identifier Printer is the array item)<br />
then there is nested list of strings, with identifiers</p>
<pre><code>A Printer
A0010 Not printing
A0020 Out of ink
A0030 No power
A0040 Noise
A0300 Feedback
A0500 Other
B PC Issues
B0010 No power
B0020 BSOD
B0030 Virus related
B0300 Feedback
B0500 Other
</code></pre>
<p>Thank you for your help</p>

<p>Which works fine.
However, when I add</p>
<pre><code>print(x.message.from)

<p>I get an error:</p>

<p>Could you please help me? How can I access fields inside 'from' block?</p>

<p>Say I have a code snippet like so:</p>
<pre class="lang-ml prettyprint-override"><code>type 'a mylist = | Nil | Cons of 'a * 'a mylist
let rec last l =
match l with
| Nil -> None
| Cons(x, Nil) -> Some(x)
| Cons(x, xs) -> last xs
</code></pre>
<p>Obviously, this pattern matches over the constructors of <code>mylist</code> - <code>Nil</code> and <code>Cons</code>.
My question is how you'd go about implementing something like this. You can't just feed values to <code>Cons</code> until you find some that match <code>l</code>, so i'm assuming the OCaml compiler implements something like a "reverse constructor" that takes a value of type <code>mylist</code> and attempts to turn it into the constituent parts?</p>
<p>For example, in psudo-ocaml:</p>
<pre class="lang-ml prettyprint-override"><code>type 'a mylist = | Nil | Cons of 'a * 'a mylist
Cons : ('a * 'a mylist) -> 'a mylist
UnCons : 'a mylist -> ('a mylist * 'a) option
</code></pre>
<p>Is this correct, or does it take another approach? What about for, say, haskell or sml?</p>

<p>How do I make the text to be justified but at the same lenght as the image above it?
I tried putting it inside a div, but it's not working, <a href="https://i.stack.imgur.com/pHSNT.png" rel="nofollow noreferrer">The text looks like this</a></p>
<p>Any tip to fix this?</p>
<p>On the code posted, I used a simple web image so it can be seen an image which helps to understand the problem. I hope that if someone can make a solution that works with that image, also works if I change the images, or if I need to keep the same size, please tell me to avoid making mistakes</p>

<p>I'm new to C++. Whenever I try to compare a string and a string from a vector, it gives me an error. I included two examples below. Why does this happen?</p>
<pre class="lang-cpp prettyprint-override"><code>#include <iostream>
#include <vector>
#include <string>
int main() {
std::string vowels = ("aeiou");
std::string whale_talk = "turpentine and turtles";
std::vector<std::string> result;
for (int i = 0; i < whale_talk.size(); i++) {
for (int x = 0; x < vowels.size(); x++) {
if (whale_talk[i] == vowels[x]) {
std::cout << whale_talk[i];
result.push_back(whale_talk[i]);
// I'm aware I'm not comparing two vectors, I added this to show that most interaction with strings will also result in an error
}
}
}
}
</code></pre>
<pre class="lang-cpp prettyprint-override"><code>#include <string>
#include <iostream>
#include <vector>
int main() {
std::vector <std::string> string_vector;
std::string string = "Hello";
std::cout << "What do you want today?";
string_vector = {"pickles"};
if (string[2] == string_vector[0]) {
std::cout << "No pickles today";
}
else {
std::cout << "We only have pickles";
}
}
</code></pre>
<p>I tried adding and removing <code>#include <string></code>, but that did not help. I also tried putting strings inside the vector before comparing it to a string.</p>

<p>I'm newer to Python. I'm using openpyxl for a SEO project for my brother and I'm trying to get a number of rows that contain a specific value in them.</p>
<p>I have a spreadsheet that looks something like this:
<a href="https://i.stack.imgur.com/qzzHd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qzzHd.png" alt="sample spreadsheet" /></a></p>
<p>I want to write a program that will get the keywords and parse them to a string by state, so like:
Missouri = "search item 1, search item 2, search item 5, search item 6"
Illinois = "search item 3, search item 4"</p>
<p>I have thus far created a program like this:</p>
<pre><code> #first, import openpyxl
import openpyxl
#next, give location of file
path = "testExcel.xlsx"
#Open workbook by creating object
wb_object = openpyxl.load_workbook(path)
#Get workbook active sheet object
sheet_object = wb_object.active
#Getting the value of maximum rows
#and column
row = sheet_object.max_row
column = sheet_object.max_column
print("Total Rows:", row)
print("Total Columns:", column)
#printing the value of forth column, state
#Loop will print all values
#of first column
print("\nValue of fourth column")
for i in range(4, row + 1):
cell_object = sheet_object.cell(row=i, column=4)
split_item_test = cell_object.value.split(",")
split_item_test_result = split_item_test[0]
state = split_item_test_result
print(state)
if (state == 'Missouri'):
print(state.count('Missouri'))
print("All good")
</code></pre>
<p>The problem is after doing this, I see that it prints 1 repeatedly, but not a total number for Missouri. I would like a total number of mentions of the state, and then eventually get it to a string with each search criteria.</p>
<p>Is this possible with openpyxl? Or will I need a different library?</p>

<p>I have to call an api that returns an array of objects:</p>
<pre><code>"supervisors": [
{
"jurisdiction": "u",
"lastName": "Olson",
"firstName": "Karson"
},
{
"jurisdiction": "9",
"lastName": "Heller",
"firstName": "Robbie"
},
{
"jurisdiction": "b",
"lastName": "Cremin",
"firstName": "Elijah"
},
]
</code></pre>
<p>The supervisors must be sorted in alphabetical order, first by jurisdiction, then my last name, finally by first name.
Then Numeric jurisdictions should be removed from the response.</p>
<p>I sorted alphabetically by:</p>
<pre><code>supervisorsObj.sort((a, b) => {
a.jurisdiction.toLowerCase().localeCompare(b.jurisdiction.toLowerCase());
});
</code></pre>
<p>But how do I remove Numeric jurisdictions if they are all strings?</p>

<p>I am getting data from an API and storing it in json format. The data I pull is in a list of dictionaries. I am using Python. My task is to only grab the information from the dictionary that matches the ticker symbol.</p>
<p>This is the short version of my data printing using json dumps</p>
<pre><code>[
{
"ticker": "BYDDF.US",
"name": "BYD Co Ltd-H",
"price": 25.635,
"change_1d_prc": 9.927101200686117
},
{
"ticker": "BYDDY.US",
"name": "BYD Co Ltd ADR",
"price": 51.22,
"change_1d_prc": 9.843448423761526
},
{
"ticker": "TSLA.US",
"name": "Tesla Inc",
"price": 194.7,
"change_1d_prc": 7.67018746889343
}
]
</code></pre>
<p>Task only gets the dictionary for ticker = TSLA.US. If possible, only get the price associated with this ticker.</p>
<p>I am unaware of how to reference "ticker" or loop through all of them to get the one I need.</p>
<p>I tried the following, but it says that its a string, so it doesn't work:</p>
<pre><code> if "ticker" == "TESLA.US":
print(i)
</code></pre>

<p>I'm trying to understand why my SVG will resize when I change the width of its parent but it won't resize when I change the height.</p>
<p>I just made a very simple jsFiddle. You can try resizing the little window at the bottom right corner.</p>
<p>From what I understand, it's key that the parent has 100% width and height so that a window resize is detected and inner svg can adjust. It's also key to specify the viewBox attribute to allow the svg to resize according to its parent div.</p>
<p>But why is it not resizing accorindg to height?</p>

<p>I tried making two input fields one for dimensions and one for weight, and both had seperate select drop down to allow the user to select a unit. <a href="https://4x.ant.design/components/input/#:%7E:text=%3CInput%20defaultValue%3D%2226888888%22" rel="nofollow noreferrer">I saw on Ant design docs that they had something similar</a>, so I tried using that.</p>
<p>This is how I wanted it to be like:
<a href="https://i.stack.imgur.com/34Llq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/34Llq.png" alt="enter image description here" /></a></p>
<p>Now i have filled my form with many other fields and they work just fine, on clicking the save button, I am not getting any data entered in the fields for dimensions or weight, nor their units. I have a standard save function which is called on 'onFinish' event:</p>
<pre><code>const handleSubmit = (data) => {
console.log('data', data);
submit(data);
};
</code></pre>
<p>This is my code to generate the fields.</p>
<pre><code><Form onFinish={handleSubmit} >
<Row style={{ justifyContent: 'left' }}>
{<Col span={8}>
<div className="p-2 lbh-input">
<Form.Item
name="dimensions"
key="dimensions"
label="Dimensions &nbsp;&nbsp; (l x b x h)">
<Input.Group>
<Input
key='length'
name='length'
style={{ width: '15%' }}
type="number"
/>
<Input
key='breadth'

style={{ width: '24%' }}

<Input

<Select name='dimension_unit' key='dimension_unit' defaultValue="cm">
<Option value="mm">mm</Option>
<Option value="cm">cm</Option>
<Option value="inch">inch</Option>
<Option value="feet">feet</Option>
<Option value="m">m</Option>
</Select>
</Input.Group>
</Form.Item>
</div>
</Col>
}
{
<div className="p-2">
<Form.Item
key="weight"
name="weight"
label="Weight">
<Input.Group>
<Input
style={{ width: '50%' }}
type="number"
key="weight"
name="weight"
label="Weight"
className='noborderradius'
/>
<Select defaultValue="kg" name="weight_unit" key="weight_unit">
<Option value="kg">kg</Option>
<Option value="tonne">tonne</Option>
<Option value="g">g</Option>
</Select>
</Input.Group>
</Form.Item>
</div>}
</Row>
<button>SUBMIT</button>
</Form>
</code></pre>
<p>As you can see, i have tried using everythihg I can like label,name,key but no matter what happens, I get no data being sent no matter what I type in these two fields. What am i missing? Am i doing something wrong with <code><Form.item></code> ?
My ant design version is</p>
<pre><code>"antd": "^4.3.4",
</code></pre>

<p>Write a program that gets a list of integers from input, and outputs non-negative integers in ascending order (lowest to highest).</p>
<p>Example: If the input is:</p>
<p>10 -7 4 39 -6 12 2</p>
<p>the output is:</p>
<p>2 4 10 12 39</p>
<p>My code that I came up with looks like this:</p>
<pre><code>user_input = input()
numbers = user_input.split()
nums = []
for number in numbers:
nums.append(int(number))
for item in nums:
if int(item) < 0:
nums.remove(item)
list.sort(nums)
for x in nums:
print(x, end=' ')
</code></pre>
<p>It gives me an 8/10 for my score but on one of the input/outputs it gives me</p>
<p>input is -1 -7 -2 -88 5 -6
my output is -88 -7 5</p>
<p>Why is it only removing some of the negative numbers and not all of them?</p>

<p>I am trying to create a list of the last days of each month for the past n months from the current date but not including current month</p>
<p>I tried different approaches:</p>
<pre><code>def last_n_month_end(n_months):
"""
Returns a list of the last n month end dates
"""
return [datetime.date.today().replace(day=1) - datetime.timedelta(days=1) - datetime.timedelta(days=30*i) for i in range(n_months)]
</code></pre>
<p>somehow this partly works if each every month only has 30 days and also not work in databricks pyspark. It returns <code>AttributeError: 'method_descriptor' object has no attribute 'today'</code></p>
<p>I also tried the approach mentioned in <a href="https://stackoverflow.com/questions/73943590/generate-a-sequence-of-the-last-days-of-all-previous-n-months-with-a-given-month">Generate a sequence of the last days of all previous N months with a given month</a></p>
<pre><code>def previous_month_ends(date, months):
year, month, day = [int(x) for x in date.split('-')]
d = datetime.date(year, month, day)
t = datetime.timedelta(1)
s = datetime.date(year, month, 1)
return [(x - t).strftime('%Y-%m-%d')
for m in range(months - 1, -1, -1)
for x in (datetime.date(s.year, s.month - m, s.day) if s.month > m else \
datetime.date(s.year - 1, s.month - (m - 12), s.day),)]
</code></pre>
<p>but I am not getting it correctly.</p>
<p>I also tried:</p>
<pre><code>df = spark.createDataFrame([(1,)],['id'])
days = df.withColumn('last_dates', explode(expr('sequence(last_day(add_months(current_date(),-3)), last_day(add_months(current_date(), -1)), interval 1 month)')))
</code></pre>
<p>I got the last three months (Sep, oct, nov), but all of them are the 30th but Oct has Oct 31st. However, it gives me the correct last days when I put more than 3.</p>
<p>What I am trying to get is this:
(last days of the last 4 months not including last_day of current_date)</p>
<p><code>daterange = ['2022-08-31','2022-09-30','2022-10-31','2022-11-30']</code></p>

<p>I'm a beginner with regex and stuck with creating regex with the following conditions:</p>
<ul>
<li>Minimum of 8 characters</li>
<li>Maximum of 60 characters</li>
<li>Must contain 2 letters</li>
<li>Must contain 1 number</li>
<li>Must contain 1 special character</li>
<li>Special character cannot be the following: & ` ( ) = [ ] | ; " ' < ></li>
</ul>
<p>So far I have the following...</p>
<pre><code>(?=^.{8,60}$)(?=.*\d)(?=[a-zA-Z]{2,})(?!.*[&`()=[|;"''\]'<>]).*
</code></pre>
<p>But my last two tests are failing and I have no idea why...</p>
<ol>
<li>!@#$%^*+-_~?,.{}!HR12345</li>
<li>123456789AB!</li>
</ol>
<p>If you'd like to see my test and expected results, visit here: <a href="https://regexr.com/73m2o" rel="nofollow noreferrer">https://regexr.com/73m2o</a></p>
<p>My tests contains acceptable number of characters, appropriate number of alphabetic characters, and supported special characters... I don't know why it's failing!</p>

<p>Can anyone clarify for me what I have shown in the 'image' attached is achievable in flutter? if yes, how? explaining the image is a bit hard.</p>
<p>I am new to flutter and trying to nest some scrollable views inside each other.</p>
<p>at first I tried to achieve this by nesting simple scrollable row and columns inside each other but faced some errors and exceptions (unbound height and width).</p>
<p>I searched and found out it is better to use 'CustomScrollView' for nesting lists in each other. tried it but haven't achieved what I want yet.
Any help/hint on how to achieve this would be much appreciated.</p>

<p>I am trying to submit a form and then the browser has to close. But I cannot understand why it will not work. For some reason, it will close the window, but it does not submit the form.</p>
<pre><code>$('.cancel-confirm').on('click', function () {
$(this).closest('form').submit();
alert('Submitted - your window will now close');
window.close();

<p>I'm using a library that itself makes the call to <code>asyncio.run(internal_function)</code> so I can't control that at all. I do however have access to the event loop, it's something that I pass into this library.</p>
<p>Given that, is there some way I can set up an recurring async event that will execute every X seconds while the main library is running.</p>
<p>This doesn't exactly work, but maybe it's close?</p>
<pre class="lang-py prettyprint-override"><code>import asyncio
from third_party import run
loop = asyncio.new_event_loop()
async def periodic():
while True:
print("doing a thing...")
await asyncio.sleep(30)
loop.create_task(periodic())
run(loop) # internally this will call asyncio.run() using the given loop
</code></pre>
<p>The problem here of course is that the task I've created is never awaited. But I can't just await it, because that would block.</p>
<p>Edit: Here's a working example of what I'm facing. When you run this code you will only ever see "third party code executing" and never see "doing my stuff...".</p>
<pre class="lang-py prettyprint-override"><code>import asyncio
# I don't know how the loop argument is used
# by the third party's run() function,
def third_party_run(loop):
async def runner():
while True:
print("third party code executing")
await asyncio.sleep(5)
# but I do know that this third party eventually runs code
# that looks **exactly** like this.
try:
asyncio.run(runner())
except KeyboardInterrupt:
return
loop = asyncio.new_event_loop()
async def periodic():
while True:
print("doing my stuff...")
await asyncio.sleep(1)
loop.create_task(periodic())
third_party_run(loop)
</code></pre>
<p>If you run the above code you get:</p>
<pre><code>third party code executing
third party code executing
third party code executing
^CTask was destroyed but it is pending!
task: <Task pending name='Task-1' coro=<periodic() running at example.py:22>>

<tr>
<th>Date</th>
<th>Value</th>
</tr>
</thead>
<tbody>
<tr>
<td>2022-10-03</td>

<tr>
<td>2022-10-04</td>
<td>y</td>
</tr>
<tr>
<td>2022-10-09</td>
<td>z</td>
</tr>
</tbody>
</table>
</div>
<p>I want to convert it to</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Date</th>
<th>Value</th>
</tr>
</thead>
<tbody>
<tr>
<td>2022-10-01</td>

<tr>
<td>2022-10-01</td>
<td>y</td>
</tr>
<tr>
<td>2022-10-08</td>
<td>z</td>
</tr>
</tbody>
</table>
</div>
<p>Is there any simple ways to do this? Thanks!</p>
<p>I tried look up but seems not finding anything neat solutions</p>

<p>I'm trying to make a SPA with html, css and vanilla JS (I have very little idea of JS). The problem I have is that the method I am using, works correctly in my header where I have only "a" with text inside. But when I want to use an img as "a", the script does not work inside the img, it only allows me to click around the img and not inside it.
I appreciate any help.
This is my script and my html in the part where I have the problem.</p>
<pre class="lang-js prettyprint-override"><code>const route = (event) => {
event = event || window.event;
event.preventDefault();
window.history.pushState({}, "", event.target.href);
handleLocation();
};
const routes = {
404: "./pages/404.html",
"/": "./pages/index.html",
"/vehicles": "./pages/vehicles.html",
"/services": "./pages/services.html",
"/contact": "./pages/contact.html",
"/financing": "./pages/financing.html",
"/locations": "./pages/locations.html",
};
const handleLocation = async () => {
const path = window.location.pathname;
const route = routes[path] || routes[404];
const html = await fetch(route).then((data) => data.text());
document.getElementById("main-page").innerHTML = html;
};
window.onpopstate = handleLocation;
window.route = route;
handleLocation();
</code></pre>

<h2>Financing</h2>

<p>I'm having some trouble with data being sent through my controller, here's a simplified example:</p>
<pre><code> public ActionResult EditNote(NotesModel model)
{
model.Author = Session["UserName"].ToString();
model.Note = null;
model.Title = null;
return View(model);
}
</code></pre>
<p>On my views page the data shown from the model is the exact same as how it was received by the method and all changes are ignored, why?</p>
<p><strong>Bigger picture:</strong></p>
<p>I'm trying to have a user edit an existing note in the database, if they're the one who made it of course. based on whether or not they're the author they will either edit the existing note or create a new note, this is where the problem lies. The controller is supposed to set all the values of the model to null so that on the views page they will be empty.
Editing an existing note is no problem however emptying the model so the editing page is blank does not work.</p>
<p><strong>EDIT</strong></p>
<p>This is my view page:</p>
<pre><code>@model WebsiteProject.Models.NotesModel
@{
ViewBag.Title = "";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@section Sidebar
{
<div id="sidebarheadericon" style="background-image: url('../Content/icons/apps.png')"></div>
<div id="headertext"><h1>Welcome</h1></div>
<hr id="seperator" />
<p class="psidebar">test</p>
<p>
@Html.ActionLink("Create New", "EditNote")
</p>
}
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h1>NotesModel</h1>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<p class="control-label">Note by @Session["UserName"].ToString()</p>
<div class="form-group">
@Html.LabelFor(model => model.Title, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Title, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Title, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Note, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Note, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Note, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="largebtn" />
</div>
</div>
<p class="text-danger">@ViewBag.NoteViewError</p>
</div>
}
<div>
@Html.ActionLink("Back to List", "NoteApp")
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
</code></pre>
<p><strong>Here you can see the data that is received</strong> (dummy data)
<a href="https://i.stack.imgur.com/JU8Mj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JU8Mj.png" alt="Data received" /></a></p>
<p><strong>Now here you'll see that the data of the model is changed</strong>
<a href="https://i.stack.imgur.com/v3yOU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/v3yOU.png" alt="Data changed" /></a></p>
<p><strong>Yet on the website it is not changed</strong>
<a href="https://i.stack.imgur.com/KSiJS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KSiJS.png" alt="Website" /></a></p>
<p>The biggest problem isn't the Note and Title not being changed because the user can do that, but the Id and Author, which the user cannot, and should not be able to change.</p>

<p>I'm working on developing both the client(C) and server(C++) side of an RF connection. I need to send a float value, but the way the architecture is set up I have to arrange my message in a struct that limits me to 3 uint8t parameters: p0, p1, p2. My solution was to break the float into an array of 4 uint8_ts and send in 2 separate messages and use p0 as an identifier whether the message contains the first or second half.</p>
<p>So far I have something like this:</p>
<p>Server (C++):</p>
<pre class="lang-cpp prettyprint-override"><code>sendFloat(float f)
{
messageStruct msg1, msg2;
uint8_t* array = (uint8_t*)(&f);
msg1.p0 = 1; //1 means it's the first half
msg1.p1 = array[0];
msg1.p2 = array[1];
msg2.p0 = 0; //0 means it's the second half
msg2.p1 = array[2];
msg2.p2 = array[3];
sendOverRf(msg1);
sendOverRf(msg2);
}
</code></pre>
<p>Client(C):</p>
<pre class="lang-cpp prettyprint-override"><code>processReceivedMessage (uint32_t id, uint32_t byteA, uint32_t byteB) //(p0,p1,p2) are routed here
{
static uint32_t firsHalfOfFloat;
uint32_t ondHalfOfFloat;
float combinedFloat;
if(id == 1) //first half
{
firstHalfOfFloat = (byteA << 8) | byteB;
}
else //second half
{
secondHalfOfFloat = (byteA << 8) | byteB;
combinedFloat = (float)((firstHalfOfFloat << 16) | secondHalfOfFloat);
}
writeFloatToFile(combinedFloat);
}
</code></pre>
<p>then on request the client must then send that float back</p>
<p>Client(C):</p>
<pre class="lang-cpp prettyprint-override"><code>sendFloatBack(uint8_t firstHalfIdentifier) // is commanded twice by server with both 0 and 1 ids
{
messageStruct msg;
float f = getFloatFromFile();
uint8_t* array = (uint8_t*)(&f);
msg.p0 = firstHalfIdentifier;
if(firstHalfIdentifier == 1) //First half
{
msg.p1 = array[0];
msg.p2 = array[1];
}
else //Second half
{
msg.p1 = array[2];
msg.p2 = array[3];
}
sendOverRf(msg);
}
</code></pre>
<p>and finally the Server (C++) gets the value back:</p>
<pre class="lang-cpp prettyprint-override"><code>retrieveFunc()
{
float f;
uint32_t firstHalf;
uint32_t secondHalf;
messageStruct msg = recieveOverRf();
firstHalf = (msg.p1 << 8) | msg.p2;
msg = receiveOverRf();
firstHalf = (msg.p1 << 8) | msg.p2;
f = (firstHalf << 16) | secondHalf;
}
</code></pre>
<p>but I'm getting really wrong values back. Any help would be great.</p>

<p>I am trying to sum up two rows. I have a table1 as the below:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>MEASURES</th>
<th>APR</th>
<th>MAY</th>
<th>JUN</th>
<th>JUL</th>
</tr>
</thead>
<tbody>
<tr>
<td>Measure 1</td>
<td>61</td>
<td>67</td>
<td>79</td>
<td>62</td>
</tr>
<tr>
<td>Measure 2</td>
<td>56</td>
<td>75</td>
<td>52</td>
<td>70</td>
</tr>
</tbody>
</table>
</div>
<p>I need to get the difference of the two rows as the below:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>MEASURES</th>
<th>APR</th>
<th>MAY</th>
<th>JUN</th>
<th>JUL</th>
</tr>
</thead>
<tbody>
<tr>
<td>Total</td>
<td>-5</td>
<td>8</td>
<td>-27</td>
<td>8</td>
</tr>
</tbody>
</table>
</div>
<p>I tried using the below statement:</p>
<pre><code>SELECT TOP(1)
'DEFICIT' AS [MEASURES]
APR - lag(APR, 1, 0) OVER (ORDER BY [MEASURES]) AS APR
,MAY - lag(MAY, 1, 0) OVER (ORDER BY [MEASURES]) AS MAY
,JUN - lag(JUN, 1, 0) OVER (ORDER BY [MEASURES]) AS JUN
,JUL - lag(JUL, 1, 0) OVER (ORDER BY [MEASURES]) AS JUL
FROM table1
ORDER BY [MEASURES] DESC;
</code></pre>
<p>But doesn't result correctly. I am not sure how to get the difference.
Can you please point me to some solution. Thanks in advance.</p>

<p>I have a running master csv file with various data columns for 896 eucalypt species (i.e., 896 rows). I recently collected new columns of information in a separate data frame, but only for 474 of those 896 species. How do I add the new columns to the master data frame and make sure they are sorted into the correct rows?</p>
<p>For example (but here I am adding 3 species' new data to a master dataset of 5 species, instead of 474 to 896): I would like to merge the following 2 data frames,</p>
<pre><code>> master
Species Variable1 Variable2
1 regnans 400 0.1
2 cornuta 421 0.1
3 caesia 378 0.2
4 viminalis 397 0.3
5 plumula 401 0.1
</code></pre>
<p>and</p>
<pre><code>> newdata
Species NewVariable
1 regnans 5
2 viminalis 9
3 plumula 7
</code></pre>
<p>into this:</p>
<pre><code>> master.updated
Species Variable1 Variable2 NewVariable
1 regnans 400 0.1 5
2 cornuta 421 0.1 NA
3 caesia 378 0.2 NA
4 viminalis 397 0.3 9
5 plumula 401 0.1 7
</code></pre>

<p>I need to write SQL query to output the Maximum number and Minimum number of movies produces by diffrent actors and actresses between year 1991 and 2001

<p>The expected result is to output the maximum numer each actor or atress produces within that year range

<p>How to improve the following batch script by making so whenever a new script is added into the directory, it doesn't require to manually hardcode an extra line of code in script.
like: <code>3) source $(pwd)/script-3.sh; myfunc;;</code></p>
<p>script:</p>
<pre><code>#Menu script
title="Menu"
prompt="Pick an option(number): "
#options=(
# "script-1.sh" \
# "script-2.sh" \
# "script-3.sh" \
# )
path=$(pwd)
array=($path/*.sh)
options=( "${array[@]##*/}" )
echo "$title"
PS3="$prompt"
select opt in "${options[@]}" "Quit"; do
case "$REPLY" in
1) source $(pwd)/script-1.sh; myfunc;;
2) source $(pwd)/script-2.sh; myfunc;;
3) source $(pwd)/script-3.sh; myfunc;;
$((${#options[@]}+1))) echo "Goodbye!"; break;;
*) echo "Invalid option. Try another one.";continue;;
esac
done
</code></pre>
<h4>How to automate this part ?</h4>
<pre><code>select opt in "${options[@]}" "Quit"; do
case "$REPLY" in
1) source $(pwd)/script-1.sh; myfunc;;
2) source $(pwd)/script-2.sh; myfunc;;
3) source $(pwd)/script-3.sh; myfunc;;

esac
done
</code></pre>
<p>this is the current manual part, where need to be hard-coded a value everytime a new script is added.</p>
<p>for example, lets say I added a new script called" <code>script-99.sh</code></p>
<p>then it would need to hardcode it in the main script like this:</p>
<pre><code> case "$REPLY" in
1) source $(pwd)/script-1.sh; myfunc;;
2) source $(pwd)/script-2.sh; myfunc;;
3) source $(pwd)/script-3.sh; myfunc;;
4) source $(pwd)/script-99.sh; myfunc;; ##Had to hardcode this line
</code></pre>

<p>I was wondering if there is a way or a resource I could refer to in order to achieve a side effect on a <code>LazyRow</code> when an item is scrolled?
The side effect is basically to call a function in the viewModel to alter the state of the list's state.</p>
<ul>
<li>The side effect should be only executed only if the current firstVisibleItemIndex after</li>
<li>scroll is different than before
The side effect should not be executed the item is not fully scrolled
I am implementing a fullscreen <code>LazyRow</code> items with a snap behavior</li>
</ul>
<p>So far I have tried <code>NestedScrollConnection</code></p>
<pre class="lang-kotlin prettyprint-override"><code>class OnMoodItemScrolled : NestedScrollConnection {
override suspend fun onPostFling(consumed: Velocity, available: Velocity): Velocity {
viewModel.fetchItems()
return super.onPostFling(consumed, available)
}
}
</code></pre>
<p>The issue with the above is that the side effect is going to be executed anyway even-though the item displayed after the scroll is the same as before the scroll.</p>
<p>I also tried to collecting the listState interaction as the following</p>
<pre class="lang-kotlin prettyprint-override"><code>val firstVisibleItem: Int = remember { sectionItemListState.firstVisibleItemIndex }
sectionItemListState.interactionSource.collectIsDraggedAsState().let {
if (firstVisibleItem != sectionItemListState.firstVisibleItemIndex) {
viewModel.fetchItems()
}
}
</code></pre>
<p>The issue with the above is that the side effect is going to be executed the second the composable is composed for the first time.</p>

<p>I have written a python for loop iteration as show below. I was wondering if its possible to convert into a recursive function.</p>
<pre><code>a = int(input("Please enter the first number: "))
b = int(input("Please enter the second number: "))
res = 0
for i in range(a,b+1):
temp = 1
for j in range(1,i+1):
temp = temp * j
res = res + temp
print("Sum of products from 1 to each integer in the range ",a," to ",b," is: ",res)
</code></pre>
<p>I am expecting something like the below example:</p>
<pre><code>def recursion(a,b):
res = 0
if condition or a while condtion
....
return ....
a = int(input("Please enter the first number: "))
b = int(input("Please enter the second number: "))
print("Sum of products from 1 to each integer in the range ",a," to ",b," is: ",res)
</code></pre>
<p>Any idea ?</p>

<p>I was given a function that I have to fill out and it has these input parameters:</p>
<pre class="lang-c prettyprint-override"><code>char * replace( const char * text, const char * (*word)[2] )
</code></pre>
<p>From my understanding, the function should return a string and is given a string in the first parameter.</p>
<p>The second parameter is an array of subarray that each have 2 strings if I'm not mistaken, but what is the meaning of the <code>*(*name)[2]</code>, what is the difference between that and <code>**name[2]</code> And how would I call this array in the function?</p>
<p>EDIT: How do I <strong>use</strong> this array in the function?</p>

<p>I try to redirect <code>domain.tld/?cur=usd</code> to <code>domain.tld</code> (there are many curencies, this is only example of one currency - we do not use anymore this solution).
I need to redirect only home with parameter to home without parameter. The other urls worked for me, I'm just having trouble getting work with that one.</p>
<p>I try to search and use online generators but none of the solutions work.
Here is what I am trying:</p>
<pre><code>RewriteCond %{QUERY_STRING} (^|&)cur\=(.*)($|&)
RewriteRule ^$ /? [L,R=301]
</code></pre>
<p>// update
before this rule I have only</p>
<pre><code>#bof redirects
RewriteEngine enabled
</code></pre>
<p>...and then there are redirects for other URLs, but I tested this rule separately first and the result was the same...</p>
<p>It not redirect me.
Thanks for the help and maybe an explanation of what I'm doing wrong.</p>

<p>I tried to sorting upper case and lower case in the perl language. A bunch of text are save in as "electricity.txt"
in the .txt file:</p>
<blockquote>
<p>Today's scientific question is: What in the world is electricity and
where does it go after it leaves the toaster?</p>
<p>Here is a simple experiment that will teach you an important
electrical lesson: On a cool dry day, scuff your feet along a carpet,
then reach your hand into a friend's mouth and touch one of his dental
fillings. Did you notice how your friend twitched violently and cried
out in pain? This teaches one that electricity can be a very powerful
force, but we must never use it to hurt others unless we need to learn
an important lesson about electricity.</p>
</blockquote>
<p>Somehow, I can't get any uppercase word
and my code is</p>
<pre><code>my %count;
my $openFileile = "electricity.txt";
open my $openFile, '<', $openFileile;
while (my $list = <$openFile>) {
chomp $list;
foreach my $word (split /\s+/, $list) {
$count{lc($word)}++;
}
}
</code></pre>
<pre><code>printf "\n\nSorting Alphabetically with upper case words in front of lower-case words with the same initial characters\n";
foreach my $word (sort keys %count){
printf "%-31s \n", sort {"\$a" cmp uc"\$b"} lc($word);
}
</code></pre>

<p>Suppose I have a <code>char</code> in the variable <code>c</code> and a positive <code>int</code> in the variable <code>n</code>. I want to build the <code>str</code> containing <code>c</code> occurring <code>n</code> times. How can I do it?</p>
<p>I tried building it as a <code>String</code>, and maybe I just got dizzy trying to read the documentation on strings, but I couldn't see how to convert it to a <code>str</code>. But then if I'm trying to just build it as a <code>str</code> directly then I couldn't see how to do that either.</p>
<p>For context, here is the full function I'm trying to implement. It takes a string and finds the longest sequence of consecutive characters (and breaks ties by taking the first that occurs).</p>
<pre><code>pub fn longest_sequence(s: &str) -> Option<&str> {
if s.len() == 0 { return None; }
let mut current_c = s.as_bytes()[0] as char;
let mut greatest_c = s.as_bytes()[0] as char;
let mut current_num = 0;
let mut greatest_num = 0;
for ch in s.chars() {
if current_c == ch {
current_num += 1;
if current_num > greatest_num {
greatest_num = current_num;
greatest_c = current_c;
}
} else {
current_num = 1;
current_c = ch;
}
}
// Now build the output str ...
}
</code></pre>

<p>Currently, I have a radial-gradient as my background with a blur effect. Without a scale effect, it has white edges around the entire gradient. To combat this, I scaled the entire gradient, which works great, except for the fact it extends the page to the right, and allows the user to scroll left and right.</p>
<p>Here is the relevant code:</p>
<pre class="lang-css prettyprint-override"><code>.gradient{
height: 75%;
width: 100%;
background: radial-gradient(62.61% 62.61% at 95.23% 6.02%, #160E71 0%, rgba(19, 13, 92, 0.26) 54.71%, rgba(90, 35, 248, 0) 100%), linear-gradient(72.48deg, #EF516D 2.61%, rgba(106, 103, 227, 0) 56.18%), radial-gradient(45.23% 45.23% at 35.11% -11.02%, #7936AE 0%, rgba(121, 54, 174, 0) 100%), radial-gradient(94.51% 124.88% at 94.32% 94.43%, rgba(65, 244, 255, 0.78) 0%, rgba(131, 218, 255, 0.6552) 32.29%, rgba(99, 175, 240, 0.3978) 64.06%, rgba(43, 90, 211, 0) 100%), linear-gradient(313.04deg, #341D65 0.93%, #604AEA 125.68%);
background-blend-mode: normal, normal, normal, normal, normal, normal;
filter: blur(100px);
transform: scale(1.4);
/* overflow: hidden; */
/* background-size: cover; */
background-clip: padding-box;
z-index: 1;
left: 0;
right: 0;
position: absolute;
}
</code></pre>
<pre class="lang-css prettyprint-override"><code>.welcome-box {

}
</code></pre>

<p>neither the <code>background-size</code> or <code>overflow</code> attribute have an effect.</p>
<p>How can I make the gradient background fit the size of the page with the scaled effect? If this is not possible, how can I remove the white edges of the gradient background without the scaling effect? Thank you!</p>
<p>Here is a video of the problem:

<p>How to make the parent layout - <code>Box</code> wrap its content in Jetpack compose?
The current implementation below fills the entire screen, I only want the <code>Box</code> to wrap around its child - <code>Switch</code>. How do I define <em>wrap content</em> for the <code>Box</code>?</p>
<pre><code>@Composable
fun TestScreen(modifier: Modifier = Modifier) {
Box(modifier = Modifier.background(Color.Yellow)){
val switchState = remember { mutableStateOf(true) }
Switch(
checked = switchState.value,
enabled= true,
onCheckedChange = { switchState.value = it }
)
}
}
</code></pre>

<p>I'm trying to get my oauth2 android app verified by the google cloud console so more than 100 users can use it but I'm stuck on this part here:
<a href="https://i.stack.imgur.com/9cLIj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9cLIj.png" alt="enter image description here" /></a></p>
<p>What does this mean? Do I need to create a website for this? Is there a way to do it for free?</p>
<p>Thanks!!</p>

<p>New to frontend and extension itself here. I tried searching and trying different things at this point. I have been to many questions like these: <a href="https://stackoverflow.com/questions/37033449/click-function-not-working-on-document-getelementsbyclassname">click function not working on document.getElementsByClassName</a> But unlike these, I am iterating through an array and not calling .click() on the array itself. This is a piece of content.ts from my extension app</p>
<p>content.ts</p>
<pre class="lang-ts prettyprint-override"><code>window.onload = function () {
let buttons = Array.from(document.getElementsByClassName("listof-buttons"));
buttons.forEach((button) => {
if (button.textContent === "Click Here") {
(button as HTMLElement).click();
}
});
};
</code></pre>
<p>The reason I am using textContent is cause there are multiple buttons with the same classname. The button does not get clicked when the window loads. (I am not waiting on an input and hence .click() and not .onClick())Any idea what I am missing here?</p>
<p>EDIT</p>
<ul>
<li>Used logging everywhere, it goes inside the if() condition</li>
<li>By "not working" I mean its not clicking on the button</li>
<li>I tried .innerHtml instead of .textContent but the results are the same</li>
</ul>
<p>manifest.json</p>

<p>I'd like to make wrapper class for manage all process about Xamarin.Essentials.Preferences.</p>
<p>There are so many overrides with different types for getting/setting in Essentials class.</p>
<p>So, I tried to change return value with generic and set value also, because I think it looks more simple.</p>
<p>But, there is an error in SetPreference method : cannot convert from 'T' to 'string'.</p>
<p>Is there any good solution for making wrapper class?</p>
<p>I want to handle all processes in here with one method.... :-(</p>

<p>I just started working with Numpy because I want to use their log method. I am trying to do -log2(79/859) but can only see how to do log2(74/571) which outputs a negative value when it should be positive. Read the Doc but don't see how to make it a negative log?</p>
<p>How can I fix this?</p>
<pre><code>print(np.log2(79/859))
</code></pre>
<p>Output</p>
<p><code>-2.947893569733893</code></p>
<p>Output I want</p>
<p><code>2.947893569733893</code></p>
<p>Tried searching through NumPy Docs</p>

<p>Could you please help me with this? Thanks</p>
<p>I found something similar here: <a href="https://stackoverflow.com/questions/3800551/select-first-row-in-each-group-by-group">Select first row in each GROUP BY group?</a></p>
<p><strong>UPDATE</strong></p>
<p>Actually I want to do the same with the following (this is a more realistic example): <a href="https://www.db-fiddle.com/f/fHc6MafduyibJdkLHe9cva/0" rel="nofollow noreferrer">https://www.db-fiddle.com/f/fHc6MafduyibJdkLHe9cva/0</a></p>

<p>I'm fairly new to window functions and have been learning about them recently. There is this query which returns the total sales for each month and quarter using a group by and an aggregate function. Additionally, it returns the total sales for the whole year (using a window function) and the max total sales for each quarter (using a window function). This all makes sense to me.</p>
<p>Query:</p>
<pre><code>SELECT
quarter(payment_date) quarter,
monthname(payment_date) month_name,
SUM(amount) monthly_sales,
MAX(SUM(amount)) OVER() max_overall_values,
MAX(SUM(amount)) OVER(PARTITION BY quarter(payment_date)) max_quarter_sales
FROM
payment
WHERE
year(payment_date) = 2005
GROUP BY
quarter(payment_date),
monthname(payment_date)
ORDER BY
monthname(payment_date) DESC;
</code></pre>
<p>Results:</p>
<pre><code>+---------+------------+---------------+--------------------+-------------------+
| quarter | month_name | monthly_sales | max_overall_values | max_quarter_sales |
+---------+------------+---------------+--------------------+-------------------+
| 2 | May | 4824.43 | 28373.89 | 9631.88 |
| 2 | June | 9631.88 | 28373.89 | 9631.88 |
| 3 | July | 28373.89 | 28373.89 | 28373.89 |
| 3 | August | 24072.13 | 28373.89 | 28373.89 |
+---------+------------+---------------+--------------------+-------------------+
</code></pre>
<p>I start to loose track of what's going on if I remove "max":</p>
<pre><code>SELECT
quarter(payment_date) quarter,
monthname(payment_date) month_name,
SUM(amount) monthly_sales,
SUM(amount) OVER() max_overall_values,
SUM(amount) OVER(PARTITION BY quarter(payment_date)) max_quarter_sales
FROM
payment
WHERE
year(payment_date) = 2005
GROUP BY
quarter(payment_date),
monthname(payment_date)
ORDER BY
monthname(payment_date) DESC;
</code></pre>
<p>I get the following results:</p>
<pre><code>+---------+------------+---------------+--------------------+-------------------+
| quarter | month_name | monthly_sales | max_overall_values | max_quarter_sales |
+---------+------------+---------------+--------------------+-------------------+
| 2 | May | 4824.43 | 19.96 | 8.98 |
| 2 | June | 9631.88 | 19.96 | 8.98 |
| 3 | July | 28373.89 | 19.96 | 10.98 |
| 3 | August | 24072.13 | 19.96 | 10.98 |
+---------+------------+---------------+--------------------+-------------------+
</code></pre>
<p>My question is what data is the "max" window function actually processing when it's used in this context, which involves a group by clause, and
how is it arriving at the calculation of 19.96 for max_overall_values, 8.98 for a quarter and 10.98 for the other when "max" is removed?</p>

<p>i'm trying to make a grid using react native that's responsive to multiple screen sizes but having troubles drawing the lines in (the sides of the box can't have a stroke).
this is what it needs to look like:
<a href="https://i.stack.imgur.com/KwVl6.png" rel="nofollow noreferrer">example grid</a>
<a href="https://i.stack.imgur.com/PjI3O.png" rel="nofollow noreferrer">my current grid</a></p>
<p>this is a small snippet:</p>
<pre><code> <View style={styles.boxContainer}>
<View style={styles.box}>
<Text style={styles.boxText}> X </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> O </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> X </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> X </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> O </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> O </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> X </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> X </Text>
</View>
<View style={styles.box}>
<Text style={styles.boxText}> O </Text>
</View>
</View>
</SafeAreaView>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
},
box: {
alignItems: 'center',
width: DeviceWidth*0.3,
height: DeviceWidth*0.3,
},
boxContainer: {
flexDirection: 'row',
flexWrap: 'wrap',
justifyContent: 'center',
marginRight: DeviceWidth*0.05,
marginLeft: DeviceWidth*0.05,
},
</code></pre>
<p>i've tried doing a border but it covers the entire thing and i'm unsure how to clear the lines on the side :( i've also tried adding a background color to my container and attempting to add space between the boxes but couldnt figure out how to make the background look similar in size..</p>

<p>I have a site where the h1 tag and an image load in when I scroll to them. I have the css set to load an animation on the tags when they load, so I really don't want them to load before they are visible.</p>
<p>I have it working perfectly on desktop/laptop, but on mobile the elements are just loaded automatically with everything else, and the animations don't have a chance to work. The console logs that I call show that the <code>window.scrollY</code> is only returning "0".</p>
<pre><code>import React, { useEffect, useState } from 'react';
import Headshot from '../../../assets/images/about/Headshot';
const About = () => {
const [isVisible, setIsVisible] = useState(true);
useEffect(() => {
document.addEventListener("touchmove", listenToScroll);
window.addEventListener("scroll", listenToScroll);
return () => {
document.addEventListener("touchmove", listenToScroll);
window.removeEventListener("scroll", listenToScroll);
}
}, [])
const listenToScroll = () => {
const homeHeight = document.getElementById('Home').clientHeight;
const folioHeight = document.getElementById('Portfolio').clientHeight;
const skillsHeight = document.getElementById('Skills').clientHeight;
let heightToShow;
let vh = window.innerHeight;
if (homeHeight > vh + 100) {
heightToShow = homeHeight - vh + folioHeight + skillsHeight;
} else {
heightToShow = 100 + folioHeight + skillsHeight;
}
const winScroll = window.scrollY;
console.log("winScroll: " + winScroll);
console.log("heightToShow: "+ heightToShow);
console.log("wS > hTS: " + (winScroll > heightToShow));
if (winScroll > heightToShow) {

} else {
setIsVisible(false);

<p>If there's a simpler solution, I am certainly open to it, but please don't just tell me "use this library, and put the tags in. It'll take care of it."
The point of this exercise is that I am trying to learn how to do it, so that I can tell if a library is a good choice for myself later.</p>

<p>I'm starting out with C# (two weeks in) and I'm trying to display a variable based on user input via Console.Readline(); method. This basic app is a calculator with two steps: Step 1 is a simple calculator; Step 2 should display material information (the name and price of the material).</p>
<p>The issue I'm having is in step 2 of my app, where I want to display the name and price of a material based on the user input. I'm not sure if LINQ is the best, easiest method for this. So open to how to solve this so it's readable by others and makes the program work.</p>
<p>Program CS. file is as follows:</p>
<pre><code>using System;
namespace Gutterjob
{
class Program
{
static void Main(String[] args)

<p>I have encountered very weird behavior using angular model when user selects from an option. I will provide screenshots + code snippets. In summary, I am getting undefined for property that is populated. Model object returns expected string but if I directly call the property, it returns undefined.</p>
<p>Object that contains all properties, followed by direct call:</p>

<p>I'm trying to assess the expected performance of calculating trigonometry functions as a function of the required precision. Obviously the wall clock time depends on the speed of the underlying arithmetic, so factoring that out by just counting number of operations:</p>
<p>Using state-of-the-art algorithms, how many arithmetic operations (add, subtract, multiply, divide) should it take to calculate <code>sin(x)</code>, as a function of the number of bits (or decimal digits) of precision required in the output?</p>

<p>I got an old .net4.8 web app that uses MVC and controllers and trying to convert(Rewrite) it to .net 7 razor pages.</p>
<p>I am trying to change the old url routing to be a standard.</p>
<p>My Razor page routeing works fine and is as follows.</p>
<pre><code>@page "/flights/{FromIata:length(3)?}/{ToIata:length(3)?}"
</code></pre>
<p>i have also tried</p>
<pre><code>@page "/flights/{FromIata?}/{ToIata?}"
</code></pre>
<p>in my program.cs I added the other route conventions.</p>
<pre><code>builder.Services.AddRazorPages()
.AddRazorPagesOptions(ops => { ops.Conventions.Insert(0, new RouteTemplateModelConventionRazorPages()); })
.AddRazorPagesOptions(options =>
{
options.Conventions.AddPageRoute("/Flights", "/flights/from-{FromIata:length(3)}-to-{ToIata:length(3)}");
options.Conventions.AddPageRoute("/Flights", "/flights/{FromIata:length(3)}-{ToIata:length(3)}");
options.Conventions.AddPageRoute("/Flights", "/flights/{FromIata:length(3)}-to-{ToIata:length(3)}");
options.Conventions.AddPageRoute("/Flights", "/flights/from-{FromIata:length(3)}-{FromCity}-to-{ToIata:length(3)}-{ToCity}");
options.Conventions.AddPageRoute("/Flights", "/flights/to-{ToIata:length(3)}");
options.Conventions.AddPageRoute("/Flights", "/flights/to-{ToIata:length(3)}-{CityName}");
options.Conventions.AddPageRoute("/Flights", "/flights/{*url}");
})
</code></pre>
<p>if I browse to the page with the standard convection it works fine but if i use any of the other conventions I get a 404 error.</p>
<p>What I am trying to do is either load the page with the other convention.
i.e /Flights/to-kul-kuala%20lumpur
or if i use that conventions it does a permanent redirect to the new url format.
i.e Flights/kul</p>
<p>Any suggestions would be greatly appreciated.</p>
<p>Thanks in advance.</p>

When i login with the required role, it always renders 'You are unauthorized to view this content' as per the RouteGuard file. The URI is /signuplist/ but still the children props are not rendered. <strong>ONLY WHEN I CLICK</strong> the button 'Todolist' (as per NavigationBar.jsx), does it go and render the child props properly. Redirection does not work as expected. <strong>I want it to directly go to /todolist and render the page, child components</strong>
Any suggestions ?</p>

<p>My understanding is that SMIL animations are supported by chrome; however my svg SMIL animation <strong>does not</strong> in Chrome (v107) while it <strong>does</strong> work in Safari (v16.0)</p>
<p>Here's a <a href="https://codepen.io/nickbewley/pen/zYjpgNR" rel="nofollow noreferrer">link</a> to a codepen illustrating the issue. Why won't this <code><animation></code> work across browsers?</p>

<p>So I've got this program that needs to take in information from a text file and use it to generate data for weather data recording stations. One of the lines looks like this:</p>
<pre><code>KE000063612 3.117 35.617 515 1/1/14 -1 87 98 73
</code></pre>
<p>the lines repeat for like 8700 lines with the same spacing, etc. how would I go about getting specific pieces of data? Like if I wanted to get the last three ints (in this case 87 98 and 73) for like four stations, or just the month of three different ones. I'm in java btw</p>
<p>I've tried using just the Column/line numbers but that's so inefficient that I really don't want to do that unless I absolutely have to.</p>

<p>iam new to flutter and i would like to add a text under a button, but i cant seems to do it, so far here's my result</p>
<p>..</p>
<p><a href="https://i.stack.imgur.com/vt9mm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vt9mm.png" alt="enter image description here" /></a></p>
<p>i use two Rows for the button and the text,
as you guys can see the text isnt align really well, i tried using ElevatedButton but the text is beside the button not below it.
this is my code so far:</p>
<pre><code>import 'package:flutter/material.dart';
import 'package:get/get_navigation/get_navigation.dart';
import 'package:medreminder/NewsArticle/news_home.dart';
import 'Reminder/ui/home_reminder.dart';
import 'Reminder/ui/widgets/button.dart';
import 'package:medreminder/main_reminder.dart';
import 'package:medreminder/home_page.dart';
void main() {
// debugPaintSizeEnabled = true;
runApp(const HomePage());
}
class HomePage extends StatelessWidget {
const HomePage({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
appBar: AppBar(
title: const Text('Medicine Reminder App'),
),
body: Column(
children: [
Stack(
children: [
Image.asset(
'images/MenuImg.jpg',
width: 600,
height: 170,
fit: BoxFit.cover,
),
],
),
const SizedBox(height: 10.0),
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
IconButton(
icon: Image.asset('images/reminder.png'),
iconSize: 50,
onPressed: () {
Navigator.of(context, rootNavigator: true).push(
MaterialPageRoute(builder: (context) => const ReminderHomePage()),
);
},
),
IconButton(
icon: Image.asset('images/news.png'),

<p>I have a list of dictionary as below.</p>
<pre><code>[
{'name':['mallesh'],'email':['m@gmail.com']},
{'name':['bhavik'],'ssn':['1000011']},
{'name':['jagarini'],'email':['m@gmail.com'],'phone':['111111']},
{'name':['mallesh'],'email':['m@gmail.com'],'phone':['1234556'],'ssn':['10000012']}

</code></pre>
<p>I would like to extract the information from these dictionary based on keys, hold on its information in another dictionary as.</p>
<pre><code>xml_master_dict={'name':[],'email':[],'phone':[],'ssn':[]}
</code></pre>
<p>Here xml_master_dict should be filled in with the respective key information as below.</p>
<p>In a fist dictionary we have this:</p>
<pre><code>{'name':['mallesh'],'email':['m@gmail.com']}
</code></pre>
<p><strong>In xml_master_dict</strong> name and email keys only will be updated with the current value, if any of key is not existed in the dictionary it should be filled in with None. in this case phone and ssn will be None</p>
<p>Here is an expected output:</p>
<pre><code>{

<p>I'm trying to setup the dev environment for an existing project on another computer under WSL2 and Windows 10. Having installed the project from its own repo with <code>composer install</code> and making sure a basic .env file is in place, I ran <code>/vendor/bin/sail up</code> to do the initial build.</p>
<p>Docker starts normally, but then during stage 4 of 11 <code>RUN apt-get update && apt-get install....</code>, it just halts when it gets to the line <code>gpg: keybox '/root/.gnupg/pubring.kbx' created</code> the build halts, the clock is still ticking but the operation never finishes.</p>
<p>I'm able to hit Ctrl + C and it Cancels cleanly.</p>
<p>Editing Laravel's dockerfile, I added a -v to the <code>gpg --recv-key ...</code> line in the script and got additional output with the operation halting after <code>gpg: connection to dirmngr established</code> instead.</p>
<p>I'm running Ubuntu under WSL2, fully updated, docker freshly installed and configured to talk to it as on my other machine where I'm not having any issues.</p>

With yarn, I can use the following command to update the library in one go, but is there a way to do the same with npm?</p>
<pre><code>$ rm -rf node_modules yarn.lock

<p>I have the following telegram export JSON dataset:</p>
<pre><code>import pandas as pd
df = pd.read_json("data/result.json")
>>>df.colums
Index(['name', 'type', 'id', 'messages'], dtype='object')
>>> type(df)
<class 'pandas.core.frame.DataFrame'>
# Sample output
sample_df = pd.DataFrame({"messages": [
{"id": 11, "from": "user3984", "text": "Do you like soccer?"},
{"id": 312, "from": "user837", "text": ['Not sure', {'type': 'hashtag', 'text': '#confused'}]},
{"id": 4324, "from": "user3984", "text": ['O ', {'type': 'mention', 'text': '@user87324'}, ' really?']}
]})
</code></pre>
<p>Within <code>df</code>, there's a <em>"messages"</em> column, which has the following output:</p>
<pre><code>>>> df["messages"]
0 {'id': -999713937, 'type': 'service', 'date': ...
1 {'id': -999713936, 'type': 'service', 'date': ...
2 {'id': -999713935, 'type': 'message', 'date': ...
3 {'id': -999713934, 'type': 'message', 'date': ...
4 {'id': -999713933, 'type': 'message', 'date': ...
...
22377 {'id': 22102, 'type': 'message', 'date': '2022...
22378 {'id': 22103, 'type': 'message', 'date': '2022...
22379 {'id': 22104, 'type': 'message', 'date': '2022...
22380 {'id': 22105, 'type': 'message', 'date': '2022...
22381 {'id': 22106, 'type': 'message', 'date': '2022...
Name: messages, Length: 22382, dtype: object
</code></pre>
<p>Within messages, there's a particular key named <em>"text"</em>, and that's the place I want to focus. Turns out when you explore the data, text column can have:</p>
<p>A single text:</p>
<pre><code>>>> df["messages"][5]["text"]
'JAJAJAJAJAJAJA'
>>> df["messages"][22262]["text"]
'No creo'
</code></pre>
<p>But sometimes it's <strong>nested</strong>. Like the following:</p>
<pre><code>>>> df["messages"][22373]["text"]
['O ', {'type': 'mention', 'text': '@user87324'}, ' really?']
>>> df["messages"][22189]["text"]
['The average married couple has sex roughly once a week. ', {'type': 'mention', 'text': '@googlefactss'}, ' ', {'type': 'hashtag', 'text': '#funfact'}]
>>> df["messages"][22345]["text"]
[{'type': 'mention', 'text': '@user817430'}]
</code></pre>
<p>In case for nested data, if I want to grab the main text, I can do the following:</p>
<pre><code>>>> df["messages"][22373]["text"][0]
'O '
>>> df["messages"][22189]["text"][0]
'The average married couple has sex roughly once a week. '
>>>
</code></pre>
<p>From here, everything seems ok. However, the problem arrives when I do the for loop. If I try the following:</p>
<pre><code>for item in df["messages"]:
tg_id = item.get("id", "None")
tg_type = item.get("type", "None")
tg_date = item.get("date", "None")
tg_from = item.get("from", "None")
tg_text = item.get("text", "None")
print(tg_id, tg_from, tg_text)
</code></pre>
<p>A sample output is:</p>
<pre><code>21263 user3984 jajajajaja
21264 user837 ['Not sure', {'type': 'hashtag', 'text': '#confused'}]
21265 user3984 What time is it?✋
</code></pre>
<p><strong>MY ASK:</strong> How to flatten the rows? I need the following (and store that in a data frame):</p>
<pre><code>21263 user3984 jajajajaja
21264 user837 Not sure
21265 user837 type: hashtag
21266 user837 text: #confused
21267 user3984 What time is it?✋
</code></pre>
<p>I tried to detect "text" type like this:</p>
<pre><code>for item in df["messages"]:
tg_id = item.get("id", "None")
tg_type = item.get("type", "None")
tg_date = item.get("date", "None")
tg_from = item.get("from", "None")
tg_text = item.get("text", "None")
if type(tg_text) == list:
tg_text = tg_text[0]
print(tg_id, tg_from, tg_text)
</code></pre>
<p>With this I only grab the first text, but I'm expecting to grab the other fields as well or to 'flatten' the data.</p>
<p>I also tried:</p>
<pre><code>for item in df["messages"]:
tg_id = item.get("id", "None")
tg_type = item.get("type", "None")
tg_date = item.get("date", "None")
tg_from = item.get("from", "None")
tg_text = item.get("text", "None")
if type(tg_text) == list:
tg_text = tg_text[0]
tg_second = tg_text[1]["text"]
print(tg_id, tg_from, tg_text, tg_second)
</code></pre>
<p>But no luck because indices are variable, length from messages are variable too.</p>
<p>In addition, even if the output weren't close of my desired solution, I also tried:</p>
<pre><code>for item in df["messages"]:
tg_text = item.get("text", "None")
if type(tg_text) == list:
for i in tg_text:
print(item, i)
</code></pre>
<pre><code>mydict = {}
for k, v in df.items():
print(k, v)
mydict[k] = v
</code></pre>
<pre><code># Used df["text"].explode()
# Used json_normalize but no luck
</code></pre>

<p>Good day</p>
<p>I moved to another company from a previous one, they task me to modify a existing system with a horrific code, but with patience and dedication, I managed to update the system, but I was shocked that they told me to put the source code on the system and it will be the one that the app in IIS will read. It will read the debug folder of the project. On my previous employer what we do is to publish the file, and that be one to read, but on my current employer,they put the whole source code on the web server.</p>
<p>Is this okay? Or am I right it's a bad practice, well other frameworks put the whole file on the server, so it should be good? Is it?</p>
<p>Thanks and regards</p>

<p>I want multiple <a href="/questions/tagged/plotly" class="post-tag" title="show questions tagged 'plotly'" aria-label="show questions tagged 'plotly'" rel="tag" aria-labelledby="plotly-container">plotly</a> figures to be displayed from an <code>if</code> <code>else</code> statement.</p>
<pre><code>if(iris$Sepal.Length < 0){print("Iris is NA.")
} else{
plot_ly(x = iris$Species, y = iris$Sepal.Length, type = "bar")
plot_ly(x = iris$Species, y = iris$Petal.Length, type = "bar")
}
</code></pre>
<p>Only the second figure appears.</p>
<p>If you do this with non-plotly figures, both are shown.</p>
<pre><code>if(iris$Sepal.Length < 0){print("Iris is NA.")
} else{
plot(iris$Sepal.Length ~ iris$Species )
plot(iris$Petal.Length ~ iris$Species)
}
</code></pre>
<p>Is there any way to make both appear?</p>

<p>I have a very large iterable which means a lot of iterations must pass before the bar updates by 1%. It populates a sqlite database from legacy excel sheets.</p>
<p>Minimum reproducible example is something like this.</p>
<pre class="lang-py prettyprint-override"><code>from tqdm import tqdm, trange
import time
percentage = 0
total = 157834
l_bar = '{desc}: {percentage:.3f}%|'
r_bar = '| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, ' '{rate_fmt}{postfix}]'
format = '{l_bar}{bar}{r_bar}'
for row in tqdm(range(2, total), ncols=100, bar_format=format):
percentage = row/total * 100
time.sleep(0.1)
</code></pre>
<p>In this example I have left all these strings as their default values except for trying to modify the percentage field in l_bar in an attempt to get decimals of a percent to print. And I haven't been able to find a default definition of <code>bar</code> anywhere in the docs so this implementation causes the loading bar to stop working.</p>
<p>From the <a href="https://github.com/tqdm/tqdm" rel="nofollow noreferrer">documentation</a>:</p>
<blockquote>
<p>bar_format : str, optional<br />
Specify a custom bar string formatting. May impact performance. [default: '{l_bar}{bar}{r_bar}'], where l_bar='{desc}: {percentage:3.0f}%|' and r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, ' '{rate_fmt}{postfix}]' Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt, percentage, elapsed, elapsed_s, ncols, nrows, desc, unit, rate, rate_fmt, rate_noinv, rate_noinv_fmt, rate_inv, rate_inv_fmt, postfix, unit_divisor, remaining, remaining_s, eta. Note that a trailing ": " is automatically removed after {desc} if the latter is empty.</p>
</blockquote>
<p>However I try it seems to come out as a flat 0% and then a jump to 1% every time.</p>
<p>How am I misunderstanding the documentation here?</p>

<p>I have a <code>try .. catch</code> block when loggin in or signing up with <code>FirebaseAuth.instance</code></p>
<p>This is the code that I have.</p>
<pre><code> try {
//... code here
} on PlatformException catch (err) {
var message = 'An error occured, please check your credentials.';
if (err.message != null) {
message = err.message!;
}
ScaffoldMessenger.of(ctx).showSnackBar(
SnackBar(
content: Text(message),
backgroundColor: Theme.of(ctx).errorColor,
),
);
// other codes here
} catch (err) {
print(err);
}
</code></pre>
<p>The problem now is that if I'm encountering an error like <code>The email address is badly formatted. </code> or <code>he email address is already in use by another account</code>, this is not going inside the <code>on PlatformException catch (err) </code> block and its goin in the <code>catch</code> block instead.</p>
<p>How can I make sure that the types of errors I mentioned above should be executed in the <code>on PlatformException</code> block?</p>

<p>In my React/Redux project I tend to use constants in switch case within <strong>reducer</strong>, since the name of each action tends to be long and complex, I'm wondering if it's a good practice?</p>
<pre class="lang-js prettyprint-override"><code>const ACTION_LIST = {
add: 'ACTION_TYPE/ADD_CUSTOMER',
remove: 'ACTION_TYPE/REMOVE_CUSTOMER',
update: 'ACTION_TYPE/UPDATE_CUSTOMER',

const reducer = produce((draft, action: IQuickBarActions) => {
const {type, payload} = action
switch (type) {
case ACTION_LIST.add: { // here
// process the state
break;
}
case ACTION_LIST.remove: {
// process the state
break;

<p>I'm working on a fun side project and would like to compute a moving sum for number of wins for NBA teams over 2 year periods. Consider the sample pandas dataframe below,</p>
<pre><code>pd.DataFrame({'Team':['Hawks','Hawks','Hawks','Hawks','Hawks'], 'Season':[1970,1971,1972,1973,1974],'Wins':[40,34,30,46,42]})
</code></pre>
<p>I would ideally like to compute the sum of the number of wins between 1970 and 1971, 1971 and 1972, 1972 and 1973, etc. An inefficient way would be to use a loop, is there a way to do this using the .groupby function?</p>

<p>I'd like to figure out a way to compare columns in the SAME data frame, but in such a way that I create a new column called <code>STATUS</code> for the output. I have 3 columns 1)<code>SNPs</code>, 2)<code>gained</code>, and 3)<code>lost</code>. I want to know if the data in each cell in column 1 is present in either column 2 or 3. If the data from column 1 is present in column 2 then I would want the output to say <code>GAINED</code>, and if its present in column 3 then the output would be <code>LOST</code>. If it's present in either then the output will be <code>NEUTRAL</code>.</p>
<p>Here is what I would like:</p>
<pre><code>SNPs GAINED LOST STATUS
1_752566 1_949654 6_30022061 NEUTRAL
1_776546 1_1045331 6_30314321 NEUTRAL
1_832918 1_832918 13_95612033 GAINED
1_914852 1_1247494 1_914852 LOST
</code></pre>
<p>I've tried this:</p>
<pre><code>data_frame$status <- data.frame(lapply(data_frame[1], `%in%`, data_frame[2:3]))
</code></pre>
<p>but it produces 2 columns that all say <code>NEUTRAL</code>. I believe it's reading per row to see if it matches, but my data isn't organized in that manner such that it will find every match per row. Instead I'd like to search the entire column and have R find the matches in each cell instead of searching per row.</p>

<p>Background:
I have an array (A) of new objects that need to be added to an array field in Mongoose. if successful it should print to screen the newly updated object but it prints null. I checked the database and confirmed it also does not update at all. I followed the docs to use the $push and $each modifiers here:
<a href="https://www.mongodb.com/docs/manual/reference/operator/update/each/" rel="nofollow noreferrer">https://www.mongodb.com/docs/manual/reference/operator/update/each/</a></p>
<p>Desired Behaviour:
I would like each object in (A) to be added to the Array field, not (A) itself. Upon success, it should print to screen the newly updated object.</p>
<p>Attempted Approach:</p>
<pre><code>let identifier={customer:{external_id:'12345'}}
let array = [{value:30},{value:30}]
User.findOneAndUpdate(identifier,{$push:{points:{$each:array}}},{new:true})
.then((result)=>{
console.log(result)
})
</code></pre>
<p>Attempted Resolutions:</p>
<ul>
<li>I tested if the issue was with the identifier parameter, but it works fine when the update parameter does not have $each (i.e. it pushes the whole array (A) into the array field)</li>
<li>I thought about using $addToSet like in the solution below, but as you can see in the sample code above, I want to push all objects even if they are not unique:
<a href="https://stackoverflow.com/questions/71448134/mongoose-push-objects-into-nested-array">Mongoose - Push objects into nested array</a></li>
</ul>

<p>I have an example below that is an extremely simplified version of my actual code.</p>
<p>I have a type that can either be an interface or another like so:</p>
<pre class="lang-js prettyprint-override"><code>interface ChatBase {
roomId?: string
type: "message" | "emoji"
configs: unknown
}
interface ChatMessage extends ChatBase {
type: "message",
configs:{
text?: string
}
}
interface ChatEmoji extends ChatBase {
type: "emoji",
configs: {
emoji?: string
}
}
type Chat = ChatMessage | ChatEmoji
</code></pre>
<p>Here is a <a href="https://www.typescriptlang.org/play?ssl=50&ssc=3&pln=25&pc=1#code/LAKFEsDsBcFMCcBmBDAxrABAYQBbOgELIDOmA3qBlRvAPa0C2AkgCYD8AXBsdPFAOaVq0AJ4AHWFwBEDWMWLJ%20sKRgA%20GKbAa0AVuClCqqWpETh%20xLgFdIAa0i0A7pFABfUB5BQ4SNJlz4ALJyCkoYsAAecJAsxNh4hCTkhhiiEtKy8orKADQpxqbmlhQg1GWpkdCc3LwCKe4gDd4IKOjx%20ACi2nrhUbAxcQGJpBglZWmSGlq6%20nml1AVmFlxj5VTTetU8fJCC81QNDaAT7dAYALxUQ8FZYepDXTOeBTwYqAmWpwDaALoXGF8Uqs1hMMiFslI5msjCYlp9gdCqHAotJtgIDPtyg0yq4odQEeNxJNNN1ZikyosiitydCNuBUbVdhjEdjqA0fs8PgA6BjIMQACne%20HOAD4EeBEIKElzKRYuXSAJQEhYmYi0AA2sC56to-H5UgAEiQMMhIOFSVIFfUUhL9XSVFA3tLZXEAGSup34GWwory0lKmkwyBqzXa3X6o1xU3mmaW62Y21C6Bck7nNNTC0Yd2e5Muv0zAOYimqjVanV6w3G-oxvRxzGHBVAA" rel="nofollow noreferrer">typescript playground</a></p>
<p>Now in my code, when I try to simply check if "emoji" is defined in <code>configs</code>, it's making it super more complicated, surely there is a simpler way?</p>
<pre class="lang-js prettyprint-override"><code>const chats: Chat[] = [
{ type: "message", configs: { text: "string" } },
{ type: "emoji", configs: { emoji: "string" } }
]
chats.map(chat=>{
if(chat.configs.emoji){ // <=== THROWS ERROR SHOWN BELOW
console.log("Has an emoji")
}
if("emoji" in chat.configs && chat.configs.emoji){ // <= Works but ridiculously long
console.log("Has an emoji")
}
if(chat.type === "emoji" && chat.configs.emoji){ // <= Works but sometimes I test for shared properties
console.log("Has en emoji")
}
})
</code></pre>
<p>But typescript is throwing me an error</p>
<pre><code>Property 'emoji' does not exist on type '{ text?: string | undefined; }'.
</code></pre>
<p>So my question is, how can I can I make <code>if("emoji" in chat.configs && chat.configs.emoji)</code> not ridiculously long?</p>

<p>I can't be the first one to ask this, but I'm having trouble finding the right search results. These terms are so overloaded.</p>
<p>Eventually I want to make some additions to a remote branch. Remote branch may not exist. So first I clone remote repo, I only have default branch locally. Then:</p>
<p>so far I have:</p>
<pre><code>git checkout -b ${BRANCHNAME} origin/${BRANCHNAME} --track || git checkout -b ${BRANCHNAME}
git add ...
git commit -m "new stuff"
git push origin ${BRANCHNAME}
</code></pre>
<p>Is there a nicer way to do the first line?</p>

<p>In SQL Server, this query runs very fast, less than a second:</p>
<pre><code>SELECT T1.id
FROM first AS T1
WHERE T1.id = 21
</code></pre>
<p>This query also runs very fast, less than a second, even though it has 53 million records but only has about six records for id 21:</p>
<pre><code>SELECT TOP 1 T2.value
FROM second AS T2 WITH(INDEX(IX_second))
WHERE T2.id = 21
AND T2.b = 1
AND T2.c = 0
AND T2.d = 0
AND T2.e = 0
ORDER BY T2.id, T2.b, T2.c, T2.d, T2.e, T2.timestamp DESC
</code></pre>
<p>However, this query, where I replace the 21 in the inner <code>SELECT</code> with T1.id, is very, very slow, more than 80 seconds:</p>
<pre><code>SELECT T1.id, T3.value
FROM first AS T1
JOIN second AS T3 ON T3.id IN (SELECT TOP 1 T2.id
FROM second AS T2 WITH(INDEX(IX_second))
WHERE T2.id = T1.id
AND T2.b = 1
AND T2.c = 0
AND T2.d = 0
AND T2.e = 0
ORDER BY T2.id, T2.b, T2.c, T2.d, T2.e, T2.timestamp DESC)
WHERE T1.id = 21
</code></pre>
<p>Why would this query take so very long and how do I make it faster?</p>

Here is the plan, with some table and field names changed to protect the innocent :) brentozar.com/pastetheplan/?id=rJYBSfwws</p>

<p>I have to generate a random walk for a sequence of positions in 2D. The person doing the random walk starts at (0,0).
At every move, she goes left, right, up or down.
The random walk stops if she comes back to (0,0), or until she made a 1000 steps.
*I am using the R language</p>
<p>I have done this so far, but I am having trouble figuring out how to stop the random walk when she reaches (0,0) again.
I only get two vectors back. Any help would be very appreciated. Thank you!</p>
<pre><code>step.max<-1000
destination<-rbind(c(0,0))
Random.walk <- function(n=step.max){
steps <- matrix(c(0,0,-1,1,0,-1,1,0),nrow = 4)
walk <- steps[sample(1:5,n,replace = TRUE)]
walk.1 <-rbind(walk)
ifelse(destination,break,apply(walk.1,2,cumsum))
}
Random.walk(n)
</code></pre>

<p>I am trying to print a string with \t at both beginning and end, like below.</p>
<pre><code>name2print="\tabhinav\t"
lastname="gupta"
print(name2print,lastname)
</code></pre>
<pre><code>Expected output should be
abhinav gupta
But the actual output is
abhinav gupta
</code></pre>
<p>I tried with lstrip like this and as expected strips only the beginning "\t" and prints the trailing "\t"</p>
<pre><code>print(name2print.lstrip(),lastname)
Output:
abhinav gupta
</code></pre>
<p>If lstrip() can print the trailing "\t" then why is the print statement ignoring the trailing tab character in the first string while printing? I think I am missing something basic. Please help.</p>

<p>I just want to create a table on HTML with a PHP loop. So, I try to do this:</p>
<pre><code><table id="tdesign">
<thead>
<tr>
<th>No</th>
<th>Nama</th>
<th>Kelas</th>
</tr>
</thead>
<tbody>
<?php $no = 1; ?>
<?php $kls = 10;?>
<?php for ($i=1; $i <= 10 ; $i++) :?>
<tr>
<td><?php echo $no++; ?></td>
<td>Name <?php echo $i; ?></td>
<?php endfor; ?>
<?php for ($j=10; $j >= 1 ; $j--) : ?>
<td><?php echo "Class ". $j . "\n" ;?></td>
<?php endfor; ?>
</tr>
</tbody>
</table>
</code></pre>
<p>But, why the output becomes this?</p>
<p><a href="https://i.stack.imgur.com/fomNM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fomNM.png" alt="enter image description here" /></a></p>

<p>I can get the rank alias with this query:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT *,
RANK() OVER (PARTITION BY some_field ORDER BY value) AS rk
FROM my_table
</code></pre>
<p>Result:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>some_field</th>
<th>value</th>
<th>rk</th>
</tr>
</thead>
<tbody>
<tr>
<td>same</td>
<td>10</td>
<td>1</td>
</tr>
<tr>
<td>same</td>
<td>20</td>
<td>2</td>
</tr>
<tr>
<td>same</td>
<td>30</td>
<td>3</td>
</tr>
</tbody>
</table>
</div>
<p>And I tried to query with:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT *,
RANK() OVER (PARTITION BY some_field ORDER BY value) AS rk
FROM my_table
WHERE rk = 1
</code></pre>
<p>I got this error message
<code>column "rk" does not exist</code></p>
<p>If I tried a subquery, it works :</p>
<pre class="lang-sql prettyprint-override"><code>SELECT *
FROM (
SELECT *,
RANK() OVER (PARTITION BY some_field ORDER BY value) AS rk
FROM my_table
) AS t
WHERE rk = 1
</code></pre>
<p>Result:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>some_field</th>
<th>value</th>
<th>rk</th>
</tr>
</thead>
<tbody>
<tr>
<td>same</td>
<td>10</td>
<td>1</td>
</tr>
</tbody>
</table>
</div>
<p>But my question is why can't we use just one SELECT to do so.</p>
<p>Is it because I use a function in my query?</p>

setMap(newMap)

<p>Then I'm returning a div with <code>id=map</code>.</p>
<p>I'm getting the error on line <code>const newMap</code>. I think we can't have 2 maps on the same page with different contents?</p>

<p>I have 621224 * 1 data in my Excel Sheet and have to calculate total no. of duplicates in the sheet but it takes a lot too much time with<code> =IF(COUNTIF($J$1000:J14353,J5353)>1,1,0)</code> so this formula might be taking n^2 complexity to find duplicates, I am looking for a formula that takes less time and if possible takes nlogn time, if there is in Excel</p>
<p>As of now I am doing this task manually taking a range of 10k which works in acceptable time and also to add on I have sorted the list
I searched for vlookup and found it will take around same time as countif</p>

<p>I placed the rectangles over the images. I then bound a click to a call that flipped tiles over by lowering the rectangle below the image. It works for the first call to the function, but when I click another tile, that one won't flip over. The program still registers the second flip because it'll flip everything back over if it's an incorrect match; the only problem is that it won't have the rectangle go under the image.</p>

<p>So I'm trying to create a BarChart for the category, and each category will have a respective color. I map this information from the MongoDB.</p>
<pre><code> const [topDepartment,setTopDepartment] = useState([])
useEffect(() =>{
const getTopDepartment = async () =>{
try {
const res = await publicRequest.get(`/order/departments`)
setTopDepartment(res.data)
setLoading(false)
} catch (error) {
}
}
getTopDepartment()
},[setTopDepartment])
</code></pre>
<p>This is the data I received</p>
<pre><code>[
{
"total": 4,
"category": "CAHS"
},
{
"total": 2,
"category": "CEIS"
}
]
</code></pre>
<p>So what I'm trying to accomplish right now is , how can I add another information inside the objects, like this.</p>
<pre><code> const updatedData = [
{
"total": 4,
"category": "CAHS"
"color": "purple"
},
{
"total": 2,
"category": "CEIS"
"color": "green"
}
]
</code></pre>
<p>Like in this image, the Bar will change it's color depending on its category

<p>I'm trying to import a route.js file in my index.js file. I am exporting in the routes file and importing it in the index with .js extension. What am I missing here?</p>
<p>Folder structure:</p>
<p>Routes folder is in the server folder, same as index.js - accessible by a single <code>.</code> VsCode also highlights the location when typing, so that's not the issue.</p>
<p>routes.js:</p>
<pre><code>import { registerUser } from '../controllers/userController'
const router = express.Router()
router.post("/", registerUser)
export default router;
</code></pre>
<p>index.js:</p>
<pre><code>import mongoose from "mongoose";
import cors from "cors";
import dotenv from "dotenv";
import userRoutes from './routes/userRoutes.js'
dotenv.config();
const app = express();
app.use(cors());
app.use('/users', userRoutes)
const PORT = process.env.PORT;
mongoose
.connect(process.env.CONNECTION_URL)
.then(() => console.log("DB Connected"))
.then(() =>
app.listen(PORT, () => console.log(`Server is running on ${PORT}`))
)
.catch((error) => console.log(error.message));

<p>this is my first time deploying <code>nodejs</code> from <code>localhost</code> to the live server. I am using <code>aapanel</code> for my live server.</p>
<p>Here is the relevant code in <code>node server.js</code> file:</p>
<pre><code>const hostname = 'localhost';
// const hostname = 'www.thespacebar.io';
// set port, listen for requests
const PORT = process.env.PORT || 8080;
app.listen(PORT, hostname, () => {
console.log(`Server is running on port ${PORT}.`);
});
</code></pre>
<p>Here is my <code>pm2</code> settings:
<a href="https://i.stack.imgur.com/qZv1z.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qZv1z.png" alt="enter image description here" /></a></p>
<p>I am unable to open my <code>nodejs</code> app with GET <code>https://www.thespacebar.io:8080</code>, but it works for GET <code>http://www.thespacebar.io:8080</code></p>
<p>GET <code>https://www.thespacebar.io:8080</code> does not work with error:</p>
<pre><code>This site can’t provide a secure connection
ERR_SSL_PROTOCOL_ERROR
</code></pre>
<p>Anyone know what I did wrong?</p>
<p><strong>EDIT</strong>: I have installed <code>Caddy</code> and setup the <code>Caddyfile</code> in <code>/etc/caddy</code> like this:</p>
<pre><code># The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.
import ./thespacebar.io
:80 {
# Set this path to your site's directory.
root * /usr/share/caddy
# Enable the static file server.
file_server
# Another common task is to set up a reverse proxy:
# reverse_proxy localhost:8080
# Or serve a PHP site through php-fpm:
# php_fastcgi localhost:9000
}
# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile
</code></pre>
<p>and created the adjacent file <code>thespacebar.io</code>:</p>
<pre><code>thespacebar.io {
reverse_proxy localhost:8080
}
</code></pre>
<p>but when I visit <code>https://thespacebar.io/</code>, I end up at <code>index.html</code> instead of the JSON <code>{ message: "Welcome to bezkoder application." }</code>
and <strong>POST</strong> <code>http://www.thespacebar.io/api/verification/callback</code> with <code>body param</code> <code>verify_token:abcde</code> is supposed to show the JSON:</p>
<pre><code>{
"message": "Callback called successfully."
}
</code></pre>
<p>instead of <code>404 Not Found</code></p>
<p><strong>EDIT 2</strong>: I have removed the portion:</p>
<pre><code># :80 {
# Set this path to your site's directory.
# root * /usr/share/caddy
# Enable the static file server.
# file_server
# Another common task is to set up a reverse proxy:
# reverse_proxy localhost:8080
# Or serve a PHP site through php-fpm:
# php_fastcgi localhost:9000
# }
# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile
</code></pre>
<p>from <code>etc/caddy/Caddyfile</code></p>
<p>but when I run <code>caddy run Caddyfile</code> and <code>caddy reload Caddyfile</code>, I am getting this error:</p>

<p>I'm using Preact with HTM (no compiler required) and am having trouble looping through an object and creating a DOM element for each item.</p>
<p>What is the correct way to procedurally generate DOM elements with Preact + HTM?</p>
<pre><code>import { h, Component, render } from 'https://unpkg.com/preact?module';
import htm from 'https://unpkg.com/htm?module';
const html = htm.bind(h);
function componentValues() {
var elements = {e1:10, e2:20};
var objEditor = '<div class="row">';
for (const key in elements) {
objEditor += '<div class="col">'+key+'</div>';
}
objEditor += '</div>';
return objEditor;
}
function renderPage() {
render(html`
<div class="container-xl">
<p>Hello World</p>
<${componentValues} />
</div>`, document.getElementById("app"));
}
renderPage();
</code></pre>
<p>My result is this</p>
<pre><code>Hello World
<div class="row"><div class="col">e1</div><div class="col">e2</div></div>

System.out.println(i1);
System.out.println(a[i1]);
}
System.out.println();
System.out.println(java.util.Arrays.toString(a));//line

<p>Consider this function</p>
<pre><code>using Distributions
using StatsBase
test_vector = sample([1,2,3], 100000000)
function test_1( test_vector)
rand_vector = randn(3333)
sum = 0.0
for t in 1:1000
if t in test_vector
sum = sum +rand_vector[t]
else
sum = sum - rand_vector[t]
end
end
end
</code></pre>
<p>I applied <code>@profview</code> to understand performance and it turns out most of the time is spent on <code>if t in test_vector</code>. Is there a way to speed up this part of the program? I thought about excluding <code>test_vector</code> from <code>1:1000</code> and run two loops, but this creates memory allocation. Can I get a hint?</p>
<p>P.S. I intend to let the user pass in any <code>test_vector</code>. I'm using <code>sample</code> to create a <code>test_vector</code> just for illustration.</p>

<p>I have a date pass from Angular frontend to Java backend.</p>
<p>The date format I received from frontend is: Wed Mon 26 11:11:59 SGT 2022 and is in Java Date object</p>
<p>How can I convert this format to dd/MM/yyyy and the final output should be 26/12/2022 <strong>in Java Date format.</strong></p>
<p><strong>Currently my code is like this:</strong></p>
<pre><code>SimpleDateFormat sdf = new SimpleDateFormat("EE MMM dd HH:mm:ss z yyyy",
Locale.ENGLISH);
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date formattedDate = dateFormat.parse(sdf.format(dateFromFrontend));
===> formattedDate to save to DB
</code></pre>
<p><strong>Parse Exception that I get:</strong></p>
<pre><code>java.text.ParseException: Unparseable date: "Mon Dec 26 12:43:19 SGT 2022"
