74,174,757 | <p>I had an error every time I restarted my App: <code>This widget has been unmounted, so the State no longer has a context (and should be considered defunct).</code> and saw that something was not correct with my initstate. The initState was:</p>
<pre><code> @override
void initState() {
SchedulerBinding.instance.addPostFrameCallback((_) {
BlocProvider.of<TutSkippedCubit>(context).load();
});
super.initState();
}
</code></pre>
<p>the methods loads the data from sharedprefs if I have already skipped the tut or not. Now I solved this issue with removing the initState method and putting the function call inside the widget build:</p>
<pre><code> @override
Widget build(BuildContext context) {
BlocProvider.of<TutSkippedCubit>(context).load();
....
</code></pre>
<p>The widget build gets called when the pages loads, so, isn't it the same as the initial state? For what exactly is the methode initState() and I have the feeling that my way of handling this problem is a bad practise, but what would be a better way, how do I solve it?</p>

74,174,768 | <p>I have the following dataset called <code>df</code>:</p>
<pre><code>structure(list(col1 = c("a b", "d e", "g f", "h j", "j k", "y z",
"e f", "b c", "f g", "c d", "y z", "t u")), class = "data.frame", row.names = c(NA,
-12L))
</code></pre>
<p>For this dataset, I have two vector with matches: A vector called <code>matching1 <- c("a b", "b c", "c d")</code> and a vector called <code>matching2 <- c("c d","e f","f g")</code>. In my <code>df</code>, I would like to create a new column and assign a value for a match. For the vector <code>matching1</code>, I would like to assign a value of 1, for the vector <code>matching2</code> I would like to assign a value of 2 and for every string not matched a value of 3. Ideally, the value assignment for vector <code>matching2</code> would not change the previous value assigment because the vector <code>matching1</code> and <code>matching2</code> both feature the string <code>"d e"</code>. I know I can use:</p>
<pre><code>matches1 <- paste0(na.omit(matching1), "", collapse = "|")
</code></pre>
<p>to create a collapsed vector with <code>or</code> and I have tried to combine it with <code>case_when</code>. However <code>case_when</code> does only allow single patterns and the list of potential matches in my original dataset is very long, so I would like to avoid spelling out every condition explicitely.</p>
<p>The output should look like this:</p>
<pre><code>structure(list(col1 = c("a b", "d e", "g f", "h j", "j k", "y z",
"e f", "b c", "f g", "c d", "y z", "t u"), col2 = c("1", "2",
"3", "3", "3", "3", "2", "1", "2", "1", "3", "3")), class = "data.frame", row.names = c(NA,
-12L))

74,174,781 | <p>I have this df and trying to clean it. How to convert irs_pop,latitude,longitude and fips in real floats and ints?
<a href="https://i.stack.imgur.com/Z7Owr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Z7Owr.png" alt="enter image description here" /></a></p>
<p>The code below returns <code>float() argument must be a string or a real number, not 'set'</code></p>
<pre><code>mask['latitude'] = mask['latitude'].astype('float64')
mask['longitude'] = mask['irs_pop'].astype('float64')
mask['irs_pop'] = mask['irs_pop'].astype('int64')
mask['fips'] = mask['fips'].astype('int64')
</code></pre>
<p>Code below returns <code>sequence item 0: expected str instance, float found</code></p>
<pre><code>mask['fips'] = mask['fips'].apply(lambda x: ','.join(x))
</code></pre>
<p><code>mask = mask.astype({'fips' : 'int64'})</code> returns <code>int() argument must be a string, a bytes-like object or a real number, not 'set'</code></p>

74,174,807 | <p>i am trying to use the isEnabled and setIsEnabled useState Hook to update the icon of the play button. When I hit the playbutton, the icon changes appropriately with the useState Hook assumingly triggering a re render, but hitting the restart btn (although i am calling the setIsEnabled) is not triggering a re render of the playbutton icon. Is there a way to force reload it or is there something I'm doing wrong with the useState hook</p>

// settings btn

};
// play & pause btn

// toggle play or pause button
setIsEnabled(!isEnabled);

} else {

<p>The issue I'm facing is that the if and the else both get executed! shouldn't the else block get executed only if the if conditions are not met? why is this happening? I want to execute the else part only if the two conditions are false!</p>

74,174,838 | <p>Here are two times in db in time format: "10:00:00" and "11:00:00".</p>
<p>I have tried to compare them:</p>
<pre><code> $starttime = Carbon::parse($icomingdate['"starttime']);
$endtime = Carbon::parser($icomingdate["endtime"]);
if($starttime + 30 > $endtime && $endtime <= '23:59:00') {
echo "Greated then start time + 30 minutes";
}
</code></pre>
<p>How to do that properly in Carbon?</p>
<p>My full code is:</p>
<pre><code> $date1 = ["date" => "2022-10-23", "starttime" => "10:00:00", "endtime" => "11:00:00"];
$date2 = ["date" => "2022-10-23", "starttime" => "11:00:00", "endtime" => "12:00:00"];
$icomedate = ["date" => "2022-10-23", "starttime" => "10:00:00", "endtime" => "10:30:00"];
$dates = [$date1, $date2];
try {
$starttime = Carbon::parse($icomedate["starttime"]);
$endtime = Carbon::parse($icomedate["endtime"]);
$date = Carbon::parse($icomedate["date"]);
$interval = 30;
if ($endtime < $starttime) {
throw new Error("End time should be greate start time");
}
if($endtime < $starttime->addMinutes($interval)) {
throw new \Exception("Interval");
}
if($endtime > $date->endOfDay()) {
throw new \Exception("End time can not be more then end of day");
}
if($starttime < $date->startOfDay()) {
throw new \Exception("End time can not be less then start of day");
}
foreach ($dates as $date) {
$stime = Carbon::parse($date["starttime"]);
$etime = Carbon::parse($date["endtime"]);
if ($starttime >= $stime && $starttime <= $etime) {
throw new \Exception("Start\Endtime time crossed");
}
}
} catch (\Exception $e) {
dd($e->getMessage());
}
</code></pre>
<p>So I try to check times for selected date.</p>

74,174,842 | <p>I've used a recursive loop to find path between words formed by one-letter changes. For example:</p>
<p>MAN-->CUT</p>
<ul>
<li>MAN</li>
<li>CAN</li>
<li>CAT</li>
<li>CUT</li>
</ul>
<p>The recursive function uses <strong>while</strong> to look at the one-letter neighbors of a word and find the neighbor that is most like the goal word. Then using that word it goes deeper, up to a depth of two more than the letter difference between the start and goal word. (This seems to be sufficient for most cases, although proving this is a whole other matter)</p>
<p>The problem is my recursive function is giving me trouble. At first I just tried to use a "break" but the recursion would keep running after. So, I searched here for methods to fix that issue. To save you reading all of the classes and functions I've made I created a stripped down version that produced the same error.</p>
<pre><code>def recurse(c):
try:
while c>0:
print(c)
c-=1
if c==5:
raise StopIteration
recurse(c-1)
except StopIteration:
print("We found the word. Stop the recursion.")
recurse(12)
</code></pre>
<p>If you run this code the exception will be raised multiple time and the recursion won't stop. I read about this method using exceptions to stop a recursion in its tracks in another post here, but the case of use was a bit different.</p>
<p>Have I implemented this incorrectly?</p>

74,174,949 | <p>I am struggling getting the difference of two Timestamps in milliseconds.</p>
<p>My current approach was</p>
<pre class="lang-sql prettyprint-override"><code>SELECT * FROM EXTRACT(EPOCH FROM(NOW()::TIMESTAMP - '2022-10-23 16:34:53.227'))
</code></pre>
<p>which was described on a bad website as returning the difference in seconds but in fact returning the difference defined as an interval.</p>
<p>It so happens, that i am unable to multiply a factor of 1000 to get the value as milliseconds.
I've then tried to cast the result as numeric or decimal, bigint, int8 and int but none these want let me use any calculation nor comparison.</p>
<p>Can someone tell me, what i am misunderstanding here?</p>

74,175,148 | <p>I created a database with sqlite3 and I want to open it in DB Browser. Problem is I have no idea where to find the database so I can open it there. And when I look in my 'sqlite3' directory under conda (I'm doing all this in jupyternotebook), I can't find any databases I created.</p>
<p>I can run other commands with this database I created so I know it exists. I just don't know where it's located.</p>
<pre><code>import sqlite3 as sql
conn = sql.connect('z')
cur = conn.cursor()
x = cur.execute('''SELECT year FROM z;''').fetchall()
print(x)
conn.close()
</code></pre>
<p>This works as a query, but I don't know where "z" is located. How do I find whre z is stored?</p>

74,175,196 | <p>I am trying to retrieve a list of elements from a webpage that contain a specific string. I'm evaluating the XPath using a selenium <code>ISearchContext.FindElement(By.XPath(...))</code>, so the XPath engine is the one supported by the browser.</p>
<p>Below is a minimal sample page created by me, but in a real world scenario I cannot modify the page's structure:</p>
<pre class="lang-html prettyprint-override"><code><html lang="en">
<head>
<title></title>
</head>
<body>
<nav>
<ul>
<li>Nav Item 1</li>
<li>Nav Item 2</li>
</ul>
</nav>
<main>
<div class="content">
<p class="description">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ab deserunt dolore eius est
facere incidunt magni
minus molestiae natus, nesciunt nostrum, officia perspiciatis placeat provident reiciendis saepe sed, sit
voluptates.</p>
<p class="price">1.150<span class="comma">,</span><sup>00</sup> <span class="currency">EUR</span></p>
</div>
<aside>
<p class="price">1.150<span class="comma">,</span><sup>00</sup> <span class="currency">EUR</span></p>
</aside>
<footer>
1<span>.</span>150<span class="comma">,</span><sup>00</sup> <span class="currency">EUR</span>
</footer>
</main>
</body>
</html>
</code></pre>
<p>The elements I'm looking for are <code>[p.price, p.price, footer]</code>; basically <strong>only</strong> the "deepest" elements containing the string <code>1.150,00 EUR</code>.</p>
<p>If I evaluate the following XPath in Chrome's Developer Tools Console</p>
<pre class="lang-js prettyprint-override"><code>$x("//*[contains(., '1.150,00 EUR')][contains(ancestor::*, '1.150,00 EUR')][not(contains(child::*, '1.150,00 EUR'))]")
</code></pre>
<p>the result I get is <code>[body, div.content, p.price, p.price, footer]</code>.</p>
<p>I'm looking for a solution that still lets me remain in the Selenium context so I can further access element properties (such as element position). It doesn't necessarily have to involve XPath and I am also open to using another browser.</p>

<p>I've looked through similar questions on stackoverflow regarding scrapy pagination issues, but none seem to reflect my issue.</p>
<p>Everything in my code works except for the section where I want to follow 'next_page' links. I have written another spider for another book website using the exact same concept and it works perfectly.
I'm failing to join the next_page link to the start url and have scrapy automatically scrape the next page.</p>
<p>Here's my code:</p>
<pre><code>import scrapy
from time import sleep
class ParariusScraper(scrapy.Spider):
name = 'pararius'
start_urls = ['https://www.pararius.com/apartments/amsterdam/']
def parse(self, response):
base_url = 'https://www.pararius.com/apartments/amsterdam'
for section in response.css('section.listing-search-item'):
yield {
'Title': section.css('h2.listing-search-item__title > a::text').get().strip(),
'Location': section.css('div.listing-search-item__sub-title::text').get().strip(),
'Price': section.css('div.listing-search-item__price::text').get().strip(),
'Size': section.css('li.illustrated-features__item::text').get().strip(),
'Link':f"{base_url}{section.css('h2.listing-search-item__title a').attrib['href']}"
}
sleep(1)
next_page = response.css('li.pagination__item a').attrib['href'].split('/')[-1]
print(next_page)
if next_page:
yield response.follow(next_page, self.parse)
</code></pre>
<p>When I run this code, the crazy think that happens is that my code only scrapes page-2 results and not even the first page which is the start_url as seen in my code.</p>
<p>I would like to know how I can fix this and have my code start working as expected. Thanks and I hope to get your support.</p>

74,175,296 | <p>I have to write a method that makes sure two objects are not on each other position-wise. The coordinates of these objects have to be randomly generated.</p>
<p>My idea is a while-loop with getX() & getY() methods, that generates new coordinates till the two objects are not on the same spot.</p>
<p>Like this:</p>
<pre><code>int x = getRandom(x);
int y = getRandom(y);
while(object1.getX() == object2.getX() && object1.getY() == object2.getY()){
int x = getRandom(min, max);
int y = getRandom(min, max);
}
</code></pre>
<p>The code works most of the time. I don't get any error messages, but in the interaction window it can be seen that the rule is not always applied. Does someone maybe have an idea, what I am doing wrong?</p>

And the sum of the local maxs is <code>3 + 1 + 6 = 10</code>. For this particular array, <code>[2, 3, 1, 4, 5, 6]</code>, this is the minimal sum of all its possible sub-array variations.</p>
<p>My approach is to first get all the possible sub-array variations for a given array. and get the min sum of them.</p>
<pre class="lang-js prettyprint-override"><code>
function getSubarrays(array, numOfSubarray) {
const results = []
const recurse = (index, subArrays) => {
if (index === array.length && subArrays.length === numOfSubarray) {
results.push([...subArrays])
return
}
if (index === array.length) return
// 1. push current item to the current subarray
// when the remaining items are more than the remaining sub arrays needed
if (array.length - index - 1 >= numOfSubarray - subArrays.length) {
recurse(
index + 1,
subArrays.slice(0, -1).concat([subArrays.at(-1).concat(array[index])])
)
}
// 2. start a new subarray when the current subarray is not empty
if (subArrays.at(-1).length !== 0)
recurse(index + 1, subArrays.concat([[array[index]]]))
}
recurse(0, [[]], 0)
return results
}
function getMinSum(arrays) {
return arrays.reduce(
(minSum, array) =>
Math.min(
minSum,
array.reduce((sum, subarray) => sum + Math.max(...subarray), 0)
),
Infinity
)
}
getMinSum(getSubarrays([[2,3], [1], [4,5,6]], 3)) // 10
</code></pre>
<p>However, I think the time complexity for my solution is really high. My guess is that it is on the order of <code>2^n</code> (feel free to correct me if I am wrong). I wonder if there is a more efficient way to calculate this.</p>

74,175,367 | <p>I'm trying to inspect the behaviour of the <code>pandas.DataFrame.groupby</code> and <code>pandas.DataFrame.pivot_table</code> methods and I've come up to this difference which I can't explain by myself.</p>
<p>It seems that the specification of <code>dropna=True</code> (default for both) has different consequences in the two cases, which might be somehow enforced by the different descriptions which are given within the docs.</p>
<p>For <a href="https://pandas.pydata.org/pandas-docs/version/1.3/reference/api/pandas.DataFrame.pivot_table.html#pandas-dataframe-pivot-table" rel="nofollow noreferrer"><code>pandas.DataFrame.pivot_table</code></a>:</p>
<blockquote>
<p>dropna: bool, default True</p>
<p><em><strong>Do not include columns whose entries are all NaN.</strong></em></p>
</blockquote>
<p>For <a href="https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.groupby.html" rel="nofollow noreferrer"><code>pandas.DataFrame.groupby</code></a>:</p>
<blockquote>
<p>dropna: bool, default True</p>
<p><em><strong>If True, and if group keys contain NA values, NA values together with row/column will be dropped. If False, NA values will also be treated as the key in groups.</strong></em></p>
</blockquote>
<p>This said, while I can totally understand the description given for the <code>.pivot_table()</code> method looking at the example I'll show in a while, I can't get through the nuances of the <code>dropna</code> behaviour in <code>.groupby()</code>.</p>
<pre><code>import pandas as pd
import numpy as np
df = pd.DataFrame({
'age': [31, np.nan, 28, 22, 54, np.nan, 49, 60, 25, np.nan],
'country_live': ['Italy', 'Spain', 'Italy', 'Spain', 'France', 'Italy', 'Spain', 'Spain', 'France', 'Spain'],
'employment_status': ['Fully employed by a company / organization', 'Partially employed by a company / organization',
'Working student', 'Working student', 'Fully employed by a company / organization', 'Partially employed by a company / organization',
'Fully employed by a company / organization', 'Fully employed by a company / organization', 'Working student',
'Partially employed by a company / organization']
},
)
df = df.assign(age=lambda t: t['age'].astype('Int64'), \
country_live=lambda t: t['country_live'].astype('category'), \
employment_status=lambda t: t['employment_status'].astype('category'))
</code></pre>
<p>With <code>.pivot_table()</code>:</p>
<pre><code>df.pivot_table(index='country_live', columns='employment_status', values='age', aggfunc='mean', dropna=True)
</code></pre>
<p><a href="https://i.stack.imgur.com/WNlEP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WNlEP.png" alt="enter image description here" /></a></p>
<p>With <code>.groupby()</code> I'd instead get (while expecting the same result obtained above):</p>
<pre><code>df.groupby(by=['country_live', 'employment_status'], dropna=True)['age'] \
.mean() \
.unstack()
</code></pre>
<p><a href="https://i.stack.imgur.com/2arlF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2arlF.png" alt="enter image description here" /></a></p>
<p>Can someone explain the reason(s) why the two do not work the same (thus implicitly explaining the behaviour of <code>dropna</code> in <code>.groupby()</code>)?</p>

74,175,371 | <p>Before rendering a page for a given route, I'd like to synchronously fetch the necessary data first. Ideally, I'd like to have the data fetching within the page component, but I'm not opposed to doing it in the router files. I've read and tried various ways of doing it, but part of the challenge comes from the fact that there are also multiple ways of building components and the usage of certain features vary.</p>
<p>In my case, I'm building single file components using the Composition API and <code><script setup></code> syntax. The <a href="https://router.vuejs.org/guide/advanced/data-fetching.html#fetching-before-navigation" rel="nofollow noreferrer">Vue Router</a> documentation link talks about "fetching before navigation" in which I could reach for <code>beforeRouteEnter</code> or <code>beforeRouteUpdate</code>, but this is shown using the Options API. They do have the page for the <a href="https://router.vuejs.org/guide/advanced/composition-api.html" rel="nofollow noreferrer">Composition API</a> mentioning I could use <code>onBeforeRouteUpdate</code>, but that uses the <code>setup()</code> function. I figured I'd try it out anyway with <code><script setup></code>:</p>
<pre class="lang-html prettyprint-override"><code><script setup>
import { onBeforeRouteUpdate } from 'vue-router'
onBeforeRouteUpdate(() => {
console.log('onBeforeRouteUpdate')
})
</script>
</code></pre>
<p>However, this does not execute. The closest method I've tried that works is fetching the data in the router, using the <code>beforeEnter</code> guard, and setting the data onto the <code>meta</code> property, which can then get accessed on the route instance in the component:</p>
<pre><code>beforeEnter: (to, from, next) => {
fetch('https://pokeapi.co/api/v2/pokemon/ditto')
.then(res => res.json())
.then(res => {
to.meta.pokemon = res;
next();
});
}
</code></pre>
<p>But with this, which is noted in the documentation, <code>beforeEnter</code> only triggers when entering the route. Params changes will not retrigger this, meaning that I'd have to set up a watcher on the route in the component anyway. I might as well just have had all this logic in the component itself.</p>
<p>I just can't seem to find a good way to do this, but I might have overlooked something. If anyone has some pointers or advice, I'd appreciate it. Thanks in advance.</p>

74,175,393 | <p>So, lets say I had a JSON File like this:</p>
<pre class="lang-json prettyprint-override"><code>{
"content": [
{
"word": "cat",
"adjectives": [
{
"type": "textile",
"adjective": "fluffy"
},
{
"type": "visual",
"adjective": "small"
}
]
},
{
"word": "dog",
"adjectives": [
{
"type": "textile",
"adjective": "fluffy"
},
{
"type": "visual",
"adjective": "big"
}
]
},
{
"word": "chocolate",
"adjectives": [
{
"type": "visual",
"adjective": "small"
},
{
"type": "gustatory",
"adjective": "sweet"
}
]
}
]
}
</code></pre>
<p>Now, say I wanted to search for two words. For example, "Fluffy" and "Small." The problem with this is that both words' adjectives contain small, and so I would have to manually search for which one contains fluffy. So, how would I do this in a quicker manner?</p>
<p>In other words, how would I find the word(s) with both "fluffy" and "small"</p>
<p>EDIT: Sorry, new asker. Anything that words in a terminal is fair game. <code>jq</code> is a really great JSON searcher, and so this is preferred, and sorry for the confusion. I also fixed the JSON</p>

74,175,401 | <p>I am having a weird issue where I change the location of all my code & data to a different location with more disk space, then I soft link my projects & data to those locations with more space. I assume there must be some file handle issue because wandb's logger is throwing me issues. So my questions:</p>
<ol>
<li>how do I have wandb only log online and not locally? (e.g. stop trying to log anything to <code>./wandb</code>[or any secret place it might be logging to] since it's creating issues). Note my code was running fine after I stopped logging to wandb so I assume that was the issue. note that the <code>dir=None</code> is the default to wandb's param.</li>
<li>how do I resolve this issue entirely so that it works seemlessly with all my projects softlinked somewhere else?</li>
</ol>

<h1>Bounty</h1>
<p>My suggestions on what might solve this are:</p>
<ol>
<li>Figuring out a way to stop wandb logging locally or minimize the amount of logging wandb is logging locally.</li>
<li>Figure out what is exactly being logged and minimize the space.</li>
<li>have the logging work even if all the folders are being symlinked. (imho this should work out of the box)</li>
<li>figuring out a systematic and simple way to find where the stale file handles are coming from.</li>
</ol>
<p>I am surprised moving <strong>everything</strong> to <code>/shared/rsaas/miranda9/</code> and running experiments from there did not solve the issue.</p>

74,175,412 | <p>I'm trying to save my commands in a folder instead of in one file to keep things organized, but I don't know how to import the commands.</p>
<p>This is the main file:</p>
<pre><code>import discord
from discord.ext import commands
client = commands.Bot(command_prefix=">")
@client.event
async def on_connect():
print(f'Logged In As {client.user}')
client.run(token)
</code></pre>
<p>And this is a test command I made:</p>
<pre><code>import discord
from discord.ext import commands
@client.command()
async def ping(ctx):
delay = client.latency * 1000
await ctx.reply(f'Ping is {int(delay)} Milliseconds')
print(f"Pinged In {ctx.guild} -- {ctx.channel}")
</code></pre>
<p>The command is saved in a folder named "commands" in the same directory as main.py. How would I import the commands?</p>
<p><strong>Sorry If The Question Is Hard To Understand, I Couldn't Find A Better Way To Put It</strong></p>

74,175,432 | <p>I have a React App(v18.2.0) with react-router-dom(v5.2.0). The navigation works correctly but when I click the browser's Back button the URL changes but no state is updated and the page doesn't get re-rendered. I tried so many different things and none of them works.</p>
<p>A case for example, is when I call the CreateUserComponent on the ListUserComponent, then if i want to go backwards using the browser back button the URL changes to the List component but the screen keeps the same.</p>

<pre><code>select id_1 as id, url, col 4,....
FROM (
SELECT origin1 as url, 'home' as source, id as id_1
FROM TableA
UNION
SELECT origin2 as url, 'home2', id

left join TableA on id_1 = TableA.id

<p>expected results:</p>

too many rows are added by the id.</p>
<p>is it possible to add the id for each row without duplication?</p>

74,175,493 | <p>Snowflake csv upload turned the date format into "0022-10-02". Is there a best way to change the "0022" format to "2022" format as <code>NEW_DATE</code> shows?</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ORDER_DATE</th>
<th>NEW_DATE</th>
</tr>
</thead>
<tbody>
<tr>
<td>0022-10-02</td>
<td>2022-10-02</td>
</tr>
<tr>
<td>0022-10-02</td>
<td>2022-10-03</td>
</tr>
</tbody>
</table>
</div>
<p>I've tried:</p>
<pre><code>df["ORDER_DATE"] = pd.to_datetime(df["ORDER_DATE"], format='%YYYY%mm%dd', errors='ignore')
def swap(x): return re.sub("^00", "20", x) if type(x) is str else x
df.applymap(swap)
print(df)
</code></pre>
<p>This still shows "0022" in the <code>ORDER_DATE</code> column.</p>
<p>I've also tried:</p>
<pre><code>df["ORDER_DATE"] = pd.DataFrame({"ORDER_DATE": ["10-02-22", "10-02-22"] })
df.apply(lambda x:x.replace("^00", "20", regex=True))
print(df)
</code></pre>
<p>Output changes the dates in the <code>ORDER_DATE</code> column but it's not ideal, because I'd like to be able to automate the date conversion process from Snowflake.</p>

74,175,514 | <p>I have a timer bar showing the remaining time of a contest. As the user answers more questions of the event, scrolling down, I want the timer to be fixed in its position. I know this can be achieved by setting the CSS <code>position</code> to <code>fixed</code>.</p>
<p>But <code>fixed</code> needs either a <code>width</code> set for the element, or <code>left</code> and <code>right</code> values. My problem is that the layout of the page is boxed, with margins at the left and right of the "box", and it depends on the user's viewport, how much width there is for the box in the middle...</p>
<p>How can I calculate the width once the page loads and then set that width to the timer bar in order for <code>fixed</code> property to get the data it needs?</p>
<p>I tried setting it to 100%, but for <code>position: fixed</code> 100% means 100% of the viewport, not of the parent element, so the bar grows from the right, outside of the viewport (if you can get what I mean), since there are margins on the left and right of the boxed layout...</p>

<p>This doesn't work. The font does not change.</p>
<p>I can change individual text widget font using the below syntax and that does work:</p>
<pre><code> Text('Some Text',
style: GoogleFonts.robotoMono(),
),
</code></pre>
<p>I have also tried downloading a font and adding it to font assets:</p>
<pre><code>fonts:
- family: Noto
fonts:
- asset: fonts/NotoSans-Regular.ttf
</code></pre>
<p>Next, I referred to it in <code>main.dart</code>, but that does not work either:</p>
<pre><code> theme: ThemeData(
fontFamily: 'Noto',
),
</code></pre>
<p>Using the below code returns <code>monospace</code>. Not sure what that is, I thought the default font should be Roboto.</p>
<pre><code>print('font: ${DefaultTextStyle.of(context).style.fontFamily}');
</code></pre>
<p>I have tried to run <code>flutter clean</code>, to uninstall the app, but none of this helps.</p>
<p>How can I go about troubleshooting this?</p>
<p><strong>UPDATE</strong></p>
<p>Found the problem. I was confused about the dark and light themes</p>

74,175,583 | <p>The Office Addin for Excel provides the method:</p>
<pre><code>OfficeRuntime.auth.getAccessToken(OfficeRuneTime.authOptions)
</code></pre>
<p>to call the Azure Active Directory, log in the user and gain access to the users profile. The method brings up a dialog box asking the users consent for the <em>Office App</em> to access their profile. The consent box also includes the grants to my Web App (Angular web site that runs in the Excel Taskpane) and includes the words <em>"If you accept, will also have access to your user profile information"</em></p>
<p>All good. But my Web App communicates with my API, which requires an additional granting of consent for my API to access the users profile.</p>
<p><strong>Is there any way to cause the dialog box invoked by 'getAcccessToken' to also grant permission to my API?</strong></p>
<p>When I login using MSAL as a fallback method (not getAccessToken(), but using an excel dialog box with MSAL configured as per the various Microsoft Walkthoughts), the consent box DOES include both my WebApp and my WebAPI. And authentication works correctly.</p>
<p>I note that the Manifest file has a tag. I had hoped that adding the Scope to my API in here would cause the Office-Addin to request consent to it, but no banana, it does nothing.</p>
<p>Any Ideas?</p>
<p>I do note that getAccessToken() deliberately does not return an access token to MS Graph, with the Microsoft Documentation citing 'security concerns', and such access to Graph must be via Server Side Code using the On-Behalf-Of flow, perhaps similar reasoning does not permit me to gain consent to any API using getAccessToken(), but what then are these section in the manifest file for? I have really struggled to get SSO working with Office Addins, there are so many nuances and unexpected behaviours.</p>

74,175,641 | <p>In the example below, classes <code>AA</code> and <code>BB</code> are instantiated with params <code>a</code> and <code>b</code> and feature the <code>foo</code> method. The only difference between classes <code>AA</code> and <code>BB</code> is that in the <code>AA</code> <code>foo</code> method, the intermediate variable <code>z</code> is prefixed with the class instance reference <code>self</code> while in class <code>BB</code> it is not. What is the correct methodology here? When should <code>self</code> be used within class methods and when should it not be used? I've always been confused by this!</p>
<pre><code>class AA:
def __init__(self, a, b):
self.a = a
self.b = b
def foo(self):
self.z = self.a + self.b
return self.z * self.a
class BB:

self.a = a
self.b = b

z = self.a + self.b

74,175,643 | <p>I'm making a turn-based grid-based game with a top-down perspective. Enemies move when the player moves, like a traditional roguelike.</p>
<p>Each character in the game (including the hero and enemies) has a futurePosition attribute that determines where they're supposed to move next. When the player presses a direction key, the hero's futurePosition is set to the direction indicated by the key, then every enemies' futurePosition is updated as well. The code in the Update() function of those characters looks like this :</p>
<pre><code>public virtual void Update() {
if (MustMoveObject()) {
transform.position = Vector3.MoveTowards(transform.position, futurePosition, inverseMoveTime * Time.deltaTime);
} else if (attacking) {
Attack();
futurePosition = Vector3Int.RoundToInt(futurePosition);
}
}
</code></pre>
<p>Note: MustMoveObject() returns true if futurePosition and transform.position are not equal</p>
<p>If the game detects there's an enemy in the direction the player is going towards, it will attack it instead. The code looks like this:</p>
<pre><code>MovingObject enemyToAttack = GameManager.instance.CheckForCreatureCurrentPosition(pos);
if (enemyToAttack != null)
{
target = enemyToAttack;
cameraFollow=false;
attacking=true;
animator.SetTrigger("attack");
futurePosition = Vector3.Lerp(transform.position, pos, 0.2f);
} else {
target=null;
cameraFollow=true;
futurePosition = pos;
}
</code></pre>
<p>As you can see in the code above, when attacking an enemy, the futurePosition attribute is set at about one fifth (or 20%) of the distance between the hero and the enemy, and "attacking" is set to true. When the player reaches that point in the Update() function, it attacks the enemy and then goes back to its original position. I hope this is clear so far.</p>
<p>Here's my problem : I recently added a test animation for the hero when it attacks, but the animation doesn't start when it should at <code>animator.SetTrigger("attack");</code>. It only activates after the movements of both the hero and the enemies is over. I know that this is the problem because if I replace the line <code>transform.position = Vector3.MoveTowards(transform.position, futurePosition, inverseMoveTime * Time.deltaTime);</code> with <code>transform.position = futurePosition;</code>, it makes the deplacement immediate and the animation triggers instantly. I want the animation to occur while the object is moving towards futurePosition.</p>
<p>Here's what the transition looks like in the inspector (I start from AnyState instead of IdleRight because I just wanted to test things out) :</p>
<p><a href="https://i.stack.imgur.com/ePDaL.png" rel="nofollow noreferrer">Screenshot</a></p>
<p>As you can see, there's no exit time. There's also no delay in the animation itself, I've checked. Everything else is working as expected.</p>
<p>I'm also using Unity version 2019.4.37f1, I'm not sure whether that's relevant.</p>
<p>I hope I made my problem clear and that someone has an idea of what to do. I've searched for a solution, but it didn't seem like anyone had the same issue. If anything, it seemed most people had the opposite problem, where the object wouldn't move as long as the animation was active...
Thanks in advance for your help.</p>

74,175,648 | <p>I am trying to create a new column in a data frame based on dates and date ranges.
I am a beginner, and have tried several of the answers here but I cannot get them to work.
Here is my original code:</p>
<pre><code> df_accident["bank_holidays_2010"] = df_accident["date"].map(
{'Easter': [d.strftime('%d/%m/%Y') for d in pd.date_range('02/04/2010', periods=4)],
'Mayday': [d.strftime('%d/%m/%Y') for d in pd.date_range('03/05/2010', periods=1)],
'Spring Bank Holiday': [d.strftime('%d/%m/%Y') for d in pd.date_range('31/05/2010', periods=1)],
'Summer Bank Holiday': [d.strftime('%d/%m/%Y') for d in pd.date_range('30/08/2010', periods=1)],
'Christmas and New Year': [d.strftime('%d/%m/%Y') for d in pd.date_range('25/12/2010', periods=9)]
}
)
</code></pre>
<p>and repeated for other years.
I get an error:</p>
<pre><code>None of [Index(['Easter', 'Mayday', 'Spring Bank Holiday', 'Summer Bank Holiday',\n 'Christmas and New Year'],\n dtype='object')] are in the [columns]"
</code></pre>
<p>I have tried:</p>
<pre><code>hols = {'Easter': [d.strftime('%d/%m/%Y') for d in pd.date_range('02/04/2010', periods=4)],
'Mayday': [d.strftime('%d/%m/%Y') for d in pd.date_range('03/05/2010', periods=1)],
'Spring Bank Holiday': [d.strftime('%d/%m/%Y') for d in pd.date_range('31/05/2010', periods=1)],
'Summer Bank Holiday': [d.strftime('%d/%m/%Y') for d in pd.date_range('30/08/2010', periods=1)],
'Christmas and New Year': [d.strftime('%d/%m/%Y') for d in pd.date_range('25/12/2010', periods=9)]
}
</code></pre>
<p>and:</p>
<pre><code>bank_holidays_2010 = {'Easter': ('02/04/2010', '03/04/2010', '05/04/2010', '06/04/2010'),
'Mayday': ('03/05/2010'),
'Spring Bank Holiday': ('31/05/2010'),
'Summer Bank Holiday': ('30/08/2010'),
'Christmas and New Year': ('25/12/2010', '26/12/2010', '27/12/2010', '28/12/2010', '29/12/2010', '30/12/2010', '31/12/2010', '01/01/2011', '02/01/2011')
}
</code></pre>
<p>Returns same error.</p>
<p>What I would like to achieve is values for the dates and date ranges:</p>
<pre><code>df_accident['bank_holidays_2010'].value_counts()
Easter 466921
Mayday 301039
Spring Bank Holiday 132195
Christmas and New Year 92931

74,175,664 | <p>Sorry if the title is a bit confusing, I wasn't sure how to word it in a couple of words.</p>
<p>I'm currently dealing with a situation where the user uploads a .csv or excel file, and the data must be mapped properly to prepare for a batch upload. It will make more sense as you read the code below!</p>
<p>First step: The user uploads the .csv/excel file, it's transformed into an array of objects. Generally the first array will be the headers.</p>
<p>The data will look like the below(including headers). This will be anywhere between 100 items to up to ~100,000 items:</p>
<pre><code>const DUMMY_DATA = [
['First Name', 'Last Name', 'company', 'email', 'phone', 'Address', 'City', 'State', 'Zip Code'],
['Lambert', 'Beckhouse', 'StackOverflow', 'lbeckhouse0@stackoverflow.com', '512-555-1738', '316 Arapahoe Way', 'Austin', 'TX', '78721'],
['Maryanna', 'Vassman', 'CDBABY', 'mvassman1@cdbaby.com', '479-204-8976', '1126 Troy Way', 'Fort Smith', 'AR', '72916']
]
</code></pre>
<p>Once this is uploaded, the user will map out each field to the proper schema. This could either be all of the fields or only a select few.</p>
<p>For instance the user only wants to exclude the address portion except for zip code.
We would get back the 'mapped fields' array, renamed to the proper schema names (i.e. First Name => firstName):</p>
<pre><code>const MAPPED_FIELDS = [firstName, lastName, company, email, phone, <empty>, <empty>, <empty>, zipCode]
</code></pre>
<p>I've made it so the indexes of the mapped fields will always match the 'headers'. So any unmapped headers will have an value.</p>
<p>So in this scenario we know to only upload the data (of DUMMY_DATA) with the indexes [0, 1, 2, 3, 4, 8].</p>
<p>We then get to the final part where we want to upload the proper fields for all the data, so we would have the properly mapped schemas from MAPPED_FIELDS matching the mapped values from DUMMY_DATA...</p>
<pre><code>const firstObjectToBeUploaded = {
firstName: 'Lambert',
lastName: 'BeckHouse',
company: 'StackOverflow',
email: 'lbeckhouse@stackoverflow.com',
phone: '512-555-1738',
zipCode: '78721'
}
try {
await uploadData(firstObjectToBeUploaded)
} catch (err) {
console.log(err)
}
</code></pre>
<p>All the data will be sent to an AWS lambda function written in Node.js to handle the upload / logic.</p>
<p>I'm struggling a bit on how to implement this efficiently as the data can get quite large.</p>

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.

74,175,703 | <p>Let's say I have a <code>UITextField</code>. I want to check if its <code>delegate</code> is set, and if so, check to see if a specific optional method is implemented. If it is implemented, then I need to call it, otherwise perform a fallback action. A common way to do this is:</p>
<pre class="lang-swift prettyprint-override"><code>let field = // some UITextField instance
if let delegate = field.delegate, delegate.responds(to: #selector(UITextFieldDelegate.textField(_:shouldChangeCharactersIn:replacementString:))) {
if delegate.textField?(field, shouldChangeCharactersIn: someRange, replacementString: someString) == true {
// do something here
}
} else {
// Fallback action
}
</code></pre>
<p>That is all working. But then I had an urge to try a different approach. Instead of using <code>responds(to:)</code> I want to assign the optional delegate method to a variable. I came up with the following which actually works:</p>
<p><strong>Note:</strong> The following code requires a deployment target of iOS 15.0 to compile. If you set the target to iOS 16.0 then it doesn't compile. Not sure why.</p>
<pre class="lang-swift prettyprint-override"><code>if let delegate = field.delegate, let should = delegate.textField {
if should(field, field.selectedRange, title) {
// do something here
}
} else {
// Fallback action
}
</code></pre>
<p>While this works I'm really confused why it works.</p>
<ol>
<li>The <code>let should = delegate.textField</code> part makes no reference to the method's parameters.</li>
<li>The <code>UITextFieldDelegate</code> protocol has 4 optional methods that start with <code>textField</code>. These are:
<ul>
<li><code>func textField(UITextField, shouldChangeCharactersIn: NSRange, replacementString: String) -> Bool</code></li>
<li><code>func textField(UITextField, editMenuForCharactersIn: NSRange, suggestedActions: [UIMenuElement]) -> UIMenu?</code></li>
<li><code>func textField(UITextField, willDismissEditMenuWith: UIEditMenuInteractionAnimating)</code></li>
<li><code>func textField(UITextField, willPresentEditMenuWith: UIEditMenuInteractionAnimating)</code></li>
</ul>
</li>
</ol>
<p>So how does this work? How does the compiler know which one I meant? It actually seems to only work with the one that happens to be first.</p>
<p>I can't find any way to do this for the other 3 delegate methods. If I really want to call the <code>func textField(UITextField, editMenuForCharactersIn: NSRange, suggestedActions: [UIMenuElement]) -> UIMenu?</code> method I can't see how. The following code will not compile:</p>
<pre class="lang-swift prettyprint-override"><code>if let delegate = field.delegate, let editMenu = delegate.textField {
let suggested = [UIMenuElement]()
if let menu = editMenu(field, field.selectedRange, suggested) {
}
}
</code></pre>
<p>This gives the error:</p>
<blockquote>
<p>Cannot convert value of type '[UIMenuElement]' to expected argument type 'String'</p>
</blockquote>
<p>on the <code>if let menu = should(field, field.selectedRange, suggested) {</code> line. This clearly indicates it is assuming the <code>func textField(UITextField, shouldChangeCharactersIn: NSRange, replacementString: String) -> Bool</code> method.</p>
<p>Is there a syntax (that I'm missing) that allows me to assign the specific protocol method to a variable?</p>
<p>I'm going to stick with the tried and true use of <code>responds(to:)</code> for now but I'd love an explanation of what's going on with the attempts to assign the ambiguously named protocol method to a variable and if there is a way to specify the parameters to get the correct assignment.</p>
<p>My searching on SO didn't yield any relevant questions/answers.</p>
<p>My code is in an iOS project with a deployment target of iOS 15.0 and later using Xcode 14.0.1. The Swift compiler setting is set for Swift 5. It seems the code doesn't compile with a deployment target of iOS 16.0. Strange.</p>

74,175,731 | <p>Not sure which details are relevant so I'll include as many as possible.</p>
<p>Had to upgrade flutter today and instead of working when I typed in 'flutter upgrade' into android studios terminal/Iterm2/terminal zsh I was met with the following response.</p>
<p>'sysctl -n hw.optional.arm64' returned unexpected output: ''</p>
<p>When I search for this issue the only thing i can <a href="https://stackoverflow.com/questions/72708385/what-may-cause-error-sysctl-n-hw-optional-arm64-returned-unexpected-output">find is this post</a> which states that sysctl can't be found. The path does appear to be in my .zshrc but still not working. I can't use which or where sysctl as it just says 'sysctl not found'</p>
<p>When I try to upgrade flutter through brew (brew install --cask flutter) it downloads fine but on installing it throws the following error:</p>
<blockquote>
<p>==> Purging files for version 3.3.5 of Cask flutter
Error: It seems there is already a Binary at '/opt/homebrew/bin/dart'.</p>
</blockquote>
<p>I can't continue working as I need the new flutter version and it seems the web doesn't have much to show for this particular error.</p>
<p>I can't flutter --version, flutter doctor or anything of the sort as I just get the same message.</p>
<p>I'm using:</p>
<ul>
<li>MacOS monterey 12.6 macbook air.</li>
<li>Android studios</li>
<li>Iterm2</li>
<li>Ohmyzsh</li>
</ul>
<p>When I open android studios it shows me the following:</p>
<ol>
<li><p>"Flutter device daemon #1 exited (exit code 1), stderr: 'sysctl -n hw.optional.arm64' returned unexpected output: '' in a pop up window.</p>
</li>
<li><p>Pubspec has been edited > get dependencies > Upgrade depenedencies: Both of which have the same error as in the title.</p>
</li>
<li><p>The current configured flutter SDK is not known to be fully supported. Please update your SDK and restart intelliJ which I think is what I've been trying to do.</p>
</li>

74,175,745 | <p>I am working on a project to let a client authorize their google ads account, and then use those authorized credentials to download data on their behalf. I have a webapp that successfully Authorizes the app to do things on the clients behalf. This generates an access code that I then trade for two credentials, an access token and a refresh token. This refresh token then gets passed to a database, where a separate app attempts to query the googleAds API.
It is my understanding that the Google Oauth engine only needs the refresh token.</p>
<p>I am trying to authorize by use of load_from_dict() or load_from_env() methods of the GoogleAdsClient class. Both yield the same error: <code>google.auth.exceptions.RefreshError: ('invalid_client: Unauthorized', {'error': 'invalid_client', 'error_description': 'Unauthorized'})</code></p>
<p>I have verified the developer_token, client_id, and client_secret are all accurate to what is in the API console. I have also verified the refresh_token is being passed correctly to the credential dict.</p>
<p>I am really at a loss on where to go from here. I have read many stack overflow threads with similar titles, and yet I am still stuck at the same place.</p>
<p>Here are some relevant links.</p>

74,175,767 | <p><strong>Example 1</strong></p>
<p>I have a code pushing one spreaded array into another:</p>
<pre><code>const hobbies = ['Sports', 'Cooking'];
const activeHobbies = ['Hiking'];
activeHobbies.push(...hobbies);
console.log(activeHobbies); //['Hiking', 'Sports', 'Cooking']
hobbies.push('Skiing');
console.log(hobbies); //['Sports', 'Cooking', 'Skiing']
console.log(activeHobbies); //['Hiking', 'Sports', 'Cooking']
</code></pre>
<p>Is a spreaded array pushed same as <code>activeHobbies.push(hobbies[0], hobbies[1])</code> by values?</p>
<p>Why is it not <code>['Hiking', 'Sports', 'Cooking', 'Skiing']</code> in the last line ?</p>
<p><strong>Example 2</strong></p>
<pre><code>const hobbies = ['Sports', 'Cooking'];
const activeHobbies = ['Hiking'];
activeHobbies.push(hobbies);
console.log(activeHobbies); //['Hiking', ['Sports', 'Cooking', 'Skiing']], why not ['Hiking', ['Sports', 'Cooking']] ?
hobbies.push('Skiing');
console.log(hobbies); //['Sports', 'Cooking', 'Skiing']
console.log(activeHobbies); //['Hiking', ['Sports', 'Cooking', 'Skiing']]
</code></pre>
<p>As I understand, <code>hobbies</code> array will be pushed to <code>activeHobbies</code> by reference without spreading like this <code>activeHobbies.push(hobbies)</code> and the new values will be added to <code>hobbies</code> array inside <code>activeHobbies</code> array, if new values are pushed to <code>hobbies</code> array, because it's pushed by reference. Is it correct?</p>
<p>But why the first console outputs <code>['Hiking', ['Sports', 'Cooking', 'Skiing']]</code> and not <code>['Hiking', ['Sports', 'Cooking']]</code> ?</p>

id = db.Column(db.Integer, primary_key=True)
property1 = db.Column(db.String(240), default = "")
property2 = db.Column(db.String(240), default = "")
property3 = db.Column(db.String(240), default = "")
</code></pre>
<p>When I try to update this model to something with an additional property (property4) shown below, the website doesn't work. Is there a way to add an additional property to a model so that the model still functions properly?</p>
<pre><code>class MyDataModel(db.Model):
id = db.Column(db.Integer, primary_key=True)
property1 = db.Column(db.String(240), default = "")
property2 = db.Column(db.String(240), default = "")
property3 = db.Column(db.String(240), default = "")
property4 = db.Column(db.String(240), default = "")
</code></pre>
<p>The db is set up like:</p>
<pre><code>db = SQLAlchemy()
app = Flask(__name__)
db.init_app(app)
</code></pre>

74,176,071 | <p>It seems that when I'm using the <code>import</code> statement in the <code><script setup></code> all code below it stops working.</p>
<p>I installed the <a href="https://heroicons.com" rel="nofollow noreferrer">@heroicons</a> package and use the import statement to use it as a component in my <code><template></code>. But everything below the import statements does not work anymore. My code:</p>
<pre class="lang-html prettyprint-override"><code><template>
<HomeIcon class="w-5 h-5">
<h1>{{myName}}</h1>
</template>
<script setup>
import {HomeIcon} from '@heroicons/vue/24/outline'
const myName = ref('username')
</script>
</code></pre>
<p>When running the code above I do <strong>not</strong> see "username" as a heading as specified in my code. I also see a ESlint warning</p>
<blockquote>
<p>myName is declared but it's value is never read</p>
</blockquote>
<p>The moment I comment the <code>import</code> statement, the <code>myName</code> ref seems to work again.</p>
<p>What I use:</p>

<li>VS Code</li>
<li>Nuxtjs 3</li>
<li>Tailwind CSS</li>

74,176,085 | <p>As summary states. Lets say I want o resolve my <em>ReturnFunction</em> in a ternary operator fashion. Well, as far as I know, as long as my function returning several values (<em>ReturnThreeValues</em>) is placed at LAST position after <em>ReturnFunction</em>'s return, the three values it gives should be returned by <em>ReturnFunction</em> if the ternary operator do what I think is the expected here, but for some reason it keeps returning <em>ReturnOneValue</em>'s value even when n == nil (because I'm not including it when calling). It can be seen & tryed here:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><script src="//github.com/fengari-lua/fengari-web/releases/download/v0.1.4/fengari-web.js"></script>
<script type="application/lua">
function ReturnOneValue(t, n)
n = n or 1
return t[n]
end
function ReturnThreeValues(t)
return t[1], t[2], t[3]
end
function ReturnFunction(t, n)
return n ~= nil and ReturnOneValue(t, n) or ReturnThreeValues(t)
end
local t = {"One", "Two", "Three"}
local r1, r2, r3 = ReturnFunction(t)
print(r1, r2, r3)
</script></code></pre>
</div>
</div>
</p>
<p>Well, basically I don't get why my print result is being: "One nil nil" and not: "One Two Three" as it should be, if the ternary operator was working as (I think is the) expected... Or is there something I'm not taking into account when it comes to resolve a multi-return function in this <em>ternary</em> way?</p>
<p><strong>EDIT:</strong></p>
<p>FTR (and just in case is useful for anyone), after doing some more research I got to find <a href="https://stackoverflow.com/a/25362653/2805176"><strong>this other question</strong></a> with a possible workaround and turns out it works, as can be seen here:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><script src="//github.com/fengari-lua/fengari-web/releases/download/v0.1.4/fengari-web.js"></script>
<script type="application/lua">
function ReturnOneValue(t, n)
n = n or 1
return t[n]
end
function ReturnThreeValues(t)
return t[1], t[2], t[3]
end
function ReturnFunction(t, n)
return n == nil and {ReturnThreeValues(t)} or {ReturnOneValue(t, n)}
end
local t = {"One", "Two", "Three"}
local r1, r2, r3 = table.unpack(ReturnFunction(t))
print(r1, r2, r3)
</script></code></pre>
</div>
</div>
</p>
<p>However, I'm not going to considerate it the right solution to the problem due to in the end it's more convoluted than what I was expecting to find, and I don't think the added complexity would worth after all... It's clear the way to go would be more in the line LMD suggests. Even though, after some consideration, I'm going to mark Nicol's answer as the right one, since he explained very well the why of such behavior and what was really happening under-the-hood, and that's what this question was actually more about. Well, thanks to everyone and I hope it makes sense.</p>

<pre><code>decimal = int(input("Enter Binary Number: "))
binary = ""
while decimal > 0:
remainder = decimal % 2
binary += str(remainder)
decimal = int(decimal / 2)
reverse = binary[::-1]
counter = 0
for i in reverse:

74,176,115 | <p>Riverpod docs say to use <code>ref.read</code> in callbacks like a button's <code>onPressed</code>, since you must not use <code>ref.watch</code> there.</p>
<p>Is it OK to do something like this?</p>
<pre><code>build(context, ref) {
// Use ref.watch ahead of time, because I refer to p all over
// the widget tree. p is a mutable ChangeNotifier
final p = ref.watch(myProvider);
return ElevatedButton(
onPressed: () {
// Refer to provider obtained via ref.watch earlier
p.mutateSomehow(),
},
child: /* huge tree referring to p 20 times */
);
}
</code></pre>
<p>? I'm doing this all over my code and it seems to work fine, but if this pattern were OK it seems like Riverpod would just recommend it and deprecate <code>ref.read</code>.</p>

74,176,134 | <p>I need a way to do the following:</p>
<ul>
<li>I want to be able to loop through each column in a data-frame that is of the <code>dtype == object</code></li>
<li>As I am looping through each desired column, I am obtaining the following summary statistics:
<ul>
<li>The name of the attribute</li>
<li>The number of unique values each attribute has</li>
<li>The most frequently occurring value of each attribute</li>
<li>The number of occurrences of the most frequently occurring value</li>
<li>The percentage of the total number of values the most frequently occurring value contributes</li>
</ul>
</li>
</ul>
<p>Say I have the following data:</p>
<pre><code>import pandas as pd
data = {"Sex":["M", "M", "F", "F", "F", "F", "M", "F", "F", "M"],
"Product": ["X", "Y", "Y", "Z","Y", "Y", "Y", "X", "Z", "Y"],
"Answer":["Yes", "Yes", "Yes", "No", "No", "Yes", "Yes", "No", "Yes", "Yes"],
"Numeric":[1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
"Binary":[True, True, False, False, False, True, False, True, True, False]}
df = pd.DataFrame(data)
</code></pre>
<p>I need some way to do the following (I know the code isn't correct - hopefully my pseudo-code conveys what I mean)</p>
<pre><code>for column in df:
if df[column].dtype != object:
continue
else:
#pseudo-code begins
attributes = df[column].name #attribute names
unique_values = df[column].unique() #number of unique values
most_frequent = df[column].mode() #most frequently occurring
occurrences = df[column][most_frequent].nunique() #occurrences of the mode
proportions = df[column][most_frequent].value_counts(normalize = True) #to get
#proportions
</code></pre>
<p>I then need some way to tabulate all this information into some kind of summary statistics table</p>
<pre><code>summaryStats = tabluate([attributes, unique_values, most_frequent, occrrences, proportions])
</code></pre>
<p>The resulting output should look something like this</p>
<pre><code>| Attribute | Unique Values | Mode | Occurrences | % of Total |
|----------- --------------- ------ ------------- ------------|
| Sex F, M, F 6 60% |
| Product X, Y, Z Y 7 70% |
| ... ... ... ... ... |
#...and so on and so forth for the other attributes
</code></pre>
<p>I am essentially creating a summary table for discrete data.</p>
<p>Any help at all would be much appreciated :)</p>

74,176,224 | <p>My predicate is <code>lll(C,R)</code> Where <code>C</code> is a country and <code>R</code> is a continent.</p>
<p>Example of data that is needed for the predicate:</p>
<pre><code>% ------------------
% country(N,C,Ar,Pop), a country N with
% capital C, area Ar and population Pop
% ------------------
country( andorra , 'Andorra la Vella' , 450 , 72766 ) .
country( angola , 'Luanda' , 1246700 , 10342899 ) .
% ------------------
% continent(N,Pop), N is a continent with population Pop.
% ------------------
continent('Europe',9562488).
% ------------------
% geo_sea(N,C,P), the sea N is in country C in province P
% ------------------
geo_sea( 'Andaman Sea' , india , 'Andaman and Nicobar Is.' ) .
% ------------------
% encompasses(C,R,Fr), country C is encompassed
% by region R to fraction Fr (percent)
%-------------------
encompasses( austria , 'Europe' ,100 ) .
encompasses( afghanistan , 'Asia' ,100 ) .
encompasses( antigua_and_barbuda , 'America' ,100 ) .
encompasses( albania , 'Europe' ,100 ) .
</code></pre>
<p>I want the biggest landlocked country so</p>
<pre><code>lll(C,R) :-
country(C,_,_,_),
continent(R,_),
not(geo_sea(_,C,_)),
encompasses(C,R,100),
setof( Circumf, circumference(Circumf,C), Cs ),
max_list(Cs,CirMax),
circumference(CirMax,C)
.
</code></pre>
<p>This is what I came up with</p>
<p>When i use this <code>lll(C,'Europe')</code> all landlocked countries get outputted instead.</p>
<p>I want the country with this biggest circumference to be outputted.
Issue right now is that the list only contains 1 element so when max is used on a list with 1 element it gets outputted.</p>
<p>Any idea how to accomplish this?</p>

74,176,390 | <p>I have a domain <code>mydomain.com</code> and a nginx space to host my website. The URL address <code>mydomain.com</code> is already in use and I don't want to buy another domain, so I created a subdomain <code>myapp.mydomain.com</code>. Then I created a laravel API app <code>myapp</code> for testing purposes and uploaded the code into <code>/mydomain_com/myapp</code> folder via a FTP client.</p>
<p>The problem now is I have to configure my <code>.htaccess</code> accordingly so the the app can run correctly.</p>
<p>At the current state, the homepage route <code>/</code> is working fine, but everything else is not working.</p>

74,176,392 | <p>I have a Firestore collection called <code>users</code> that stores all my user info. When registering a new user, I first register them with Firebase Auth, then create the record in the <code>users</code> collection. Right now I'm storing the <code>UID</code> as a field, which means when I want to query a user's info, I need to do a query with a <code>WHERE</code> clause. However, one alternative to faster querying would be to store the <code>UID</code> as the document ID for the collection. That would make it so that I could query the collection with a specific ID, which intuitively seems faster.</p>
<p>Using the <code>UID</code> as the doc ID makes me worried about some stuff:</p>
<ol>
<li>I'm not sure if I can assume that uniqueness for the <code>UID</code> in Firebase Auth implies uniqueness when using it as the doc ID in a Firestore collection.</li>
<li>I watched a tutorial video by Todd that said that querying is faster if you use the auto-generated document ID that Firestore provides. Given this, I wouldn't want to take a risk using something else when the provided doc ID is known to be faster for querying.</li>
</ol>
<p>What would be the better approach to make querying as efficient as possible, assuming you are querying only based on <code>UID</code>? Or is the difference so negligible that this is a moot point?</p>

b = "Smith"
if b in a:
print("True")
else:

Can someone explain why this happens?</p>

74,176,450 | <p>I have an array of times (these are not constant) <code>[1:00, 2:00, 3:00, 4:00, 5:00, 6:00, 7:00]</code>. The goal is to calculate times that can be bookable. If there is an existing booking from <code>4:00 - 5:00</code> then <code>3:00</code> should be unavailable as it would overlap the existing booking. To calculate this, I have a function that tells us the start and end indexes of the booking, I need to find a way to remove x times from <strong>behind</strong> the start index.</p>
<p>To make it more clear, I drew a diagram.</p>
<p><a href="https://i.stack.imgur.com/ugLeH.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ugLeH.jpg" alt="problem diagram" /></a></p>
<p>Doing this calculation will allow to calculate available times no matter how long the existing booking is. I'm trying to figure out how to create a function that does what I described. Below is the code I have to return the available times based on the start/end index provided however I'm stuck on how to approach the calculation I described above.</p>
<pre><code> // This filters times that are less than the start index
const filteredTimes1 = availableHours.filter((item, index) => index < (
(startTimeIndex || availableHours.length - 0)
))
// This filters times that greater than the end index
const filteredTimes2 = availableHours.filter((item, index) =>
index > (endTimeIndex || availableHours.length)
)
// Then combine the results into an array
const validAvailableHours = [...filteredTimes1 , ...filteredTimes2]
</code></pre>

74,176,471 | <p>For a uni assignment, a function "lookup" has been defined as:</p>

<p>The "Env" keyword has been defined as:</p>
<pre><code>import qualified Data.Map as M
newtype Env e = Env (M.Map String e) deriving (Functor, Foldable, Traversable, Show, Eq, Monoid, Semigroup)
</code></pre>
<p>I understand that the double colon "::" means "has type of". So the lookup function takes two arguments and returns something. I know the second argument is a string, however, I'm struggling to understand the first argument and the output. What is the "Env" type and what does the "e" after it represent. It feels like e is an argument to "Env" but if that is the case, the output wouldn't make sense.</p>

the largest of the inputs
the number of even inputs
the number of odd inputs
the average of all of the inputs</p>
<p>You do not know how many numbers the user will want to type in, so you must ask her each time if she has another number to add to the sequence.</p>

total = 0
# option variable is to store the user option Y or N
option = 'y'
# declare variables to count odd, even and totalCount
evenCount = 0
oddCount = 0
totalCount = 0

# run the loop when the user enters y or Y
while option == 'y' or option == 'Y':
# take input of number
number = int(input("Please type a number: "))
# add the number to total
total = total + number

else:
oddCount = oddCount + 1

74,176,515 | <p>I am trying to make an app that will display the weather data after the user enters a city. I am using the openweathermap.org API. In my console under networks it shows that I am making an API call when I enter the city but no data is returning. The missing data that should display is the city name, the temperature and the weather. Please advise on how I can fix this.</p>
<p>App.js:</p>
<pre><code>import React, { useState } from 'react';
import './App.css';
function App() {
const apiKey = 'API Key'; //I entered my API key here
const [weatherData, setWeatherData] = useState([{}]);
const [city, setCity] = useState('');
const getWeather = (event) => {
if (event.key == 'Enter') {
fetch(
'https://api.openweathermap.org/data/2.5/weather?q=s{city}&units=imperil&APPID=${apiKey}' //I copied this api from the tutorial
)
.then((response) => response.json())
.then((data) => {
setWeatherData(data);
setCity('');
});
}
};
return (
<div className="container">
<input
className="input"
placeholder="Enter City..."
onChange={(e) => setCity(e.target.value)}
value={city}
onKeyPress={getWeather}
/>
{typeof weatherData.main === 'undefined' ? (
<div>
<p>Welcome to weather app! Enter the city you want the weather of.</p>
</div>
) : (
<div className="weather-data">
<p className="city">{weatherData.name}</p>
<p className="temp">{Math.round(weatherData.main.temp)}℉</p>
<p className="weather">{weatherData.weather[0].main}</p>
</div>
)}
{weatherData.cod === '404' ? <p>City not found.</p> : <></>}
</div>
);
}
export default App;
</code></pre>

74,176,540 | <p>I am trying to call the class <em>FileRead</em> and methods <em>Display</em> and <em>Contents</em> from another separate class, however it is within the same package. This is my main class. It works within Eclipse. I can type in a text file and it displays it. This class also compiles and runs in command prompt.</p>
<pre><code>public class FileRead
{
static String theFile;
Scanner myScanner = new Scanner (System.in);
static List<String> fileArray = new ArrayList<String>();
static StringBuffer stringBuff = new StringBuffer();
public FileRead()
{
System.out.println ("Enter your file: ");
theFile = myScanner.nextLine();
try
{
myScanner = new Scanner(new File(theFile));
FileReader myFileReader = new FileReader(theFile);
BufferedReader buffRead = new BufferedReader(myFileReader);
while ((theFile = buffRead.readLine()) != null)
{
fileArray.add(theFile);
}
buffRead.close();
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
}
public String Contents()
{
for (String str : fileArray)
{
stringBuff.append(str);
stringBuff.append("\n");
}
String str = stringBuff.toString();
return (str);
}
public void Display()
{
for (int i = 0; i < fileArray.size(); i++)
{
System.out.println ("Line # " + (i + 1) + " " + fileArray.get(i));
}
}
public static void main (String[] args)
{
//FileRead textFile = new FileRead();
//textFile.Display();
//textFile.Contents();
}
}
</code></pre>
<p>The problem I am having is with this class:</p>
<pre><code>public class FileReadShow
{
public static void main (String[] args)
{
try
{
FileRead myTextFile = new FileRead();
myTextFile.Contents();
myTextFile.Display();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
</code></pre>
<p>When I try to compile this in the command prompt, I get this:</p>
<pre><code>javac filereadshow.java
filereadshow.java:112: error: cannot find symbol
FileRead myTextFile = new FileRead();
^
symbol: class FileRead
location: class FileReadShow
filereadshow.java:112: error: cannot find symbol
FileRead myTextFile = new FileRead();
^
symbol: class FileRead
location: class FileReadShow
2 errors
</code></pre>
<p>I've done some searching around and found the main causes of these errors. I didn't find any typos. I also tried removing one <em>main</em> methods from one of these classes but that hadn't worked either. One thing I'm still unsure of is undeclared variables, which is my first question.</p>
<p>1: I am new to constructors, and it looks correct to me, but could the problem be that I have incorrectly called the reference to the object where the <em>FileRead</em> constructor is?</p>
<p>2: I have narrowed the errors down to this statement alone <code>FileRead myTextFile = new FileRead();</code> because no matter what I do with it, this is where the errors are. Could someone please help me determine if the problem is with the <em>FileRead</em> script itself, or with the object reference <code>FileRead myTextFile = new FileRead();</code>?</p>
<p>Thanks for your time!</p>
<p>EDIT: FileRead.class is in the current directory as I am able to compile it. I compiled that before trying FileReadShow.</p>
<p>EDIT #2: I switched IDE's and found more information which gave me two compile error descriptions:</p>
<pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problems: -FileRead cannot be resolved to a type
-FileRead cannot be resolved to a type
</code></pre>
<p>So far there doesn't seem to be a very definitive answer. I am currently working through fixes that have worked for other people. Such as restarting eclipse/PC, using the "clean" option in the file drop down menu, creating a new class, etc. So far nothing has worked. I will keep trying. Does anyone have any more suggestions I could try?</p>
<p>EDIT #3: Both of my .java files are inside of the package folder that contains everything for Eclipse (.CLASSPATH, .project, src folder, bin folder, etc). Normally when I change directories in command prompt, I go to this package folder and can compile with ease. My exact command prompt input is:</p>
<pre><code>C:\Users\D>cd eclipse-workspace\packageone\src\packageone
C:\Users\D\eclipse-workspace\PackageOne\src\PackageOne>javac fileread.java
//As you can see the first one compiled, so I call the second below
C:\Users\D\eclipse-workspace\PackageOne\src\PackageOne>javac filereadshow.java
filereadshow.java:90: error: cannot find symbol
FileRead myTextFile = new FileRead();
^
symbol: class FileRead
location: class FileReadShow
filereadshow.java:90: error: cannot find symbol
FileRead myTextFile = new FileRead();
^
symbol: class FileRead
location: class FileReadShow
2 errors
</code></pre>
<p>The first .java file (FileRead.java) compiled, the second one (.FileReadShow.java) still results in errors. What am I doing wrong? I've compiled dozens of programs this way and haven't run into this...?</p>

74,176,557 | <h2>Introduction</h2>
<p>I recently learned how to plot <code>Simple Moving Averages</code> (<em>abbreviated "SMA"</em>) using the <a href="https://github.com/matplotlib/mplfinance" rel="nofollow noreferrer"><code>MatPlotLibFinance</code></a> library on <code>Python3</code>. <code>Simple Moving Averages</code> are trend lines that They help the investor in determining the best times to enter to buy or sell an asset.</p>
<h2>Data</h2>
<p>The following variables contain the data used in the Script to plot the price action, the first variable was named <code>df_trading_pair</code> and contains the following information:</p>
<div class="s-table-container">
<table class="s-table">

<p>Also, another variable called <code>df_trading_pair_date_time_index</code> contains the same information as the previous variable with slight modifications, since it can only be used in this way in the script below:</p>
<pre><code>def set_DateTimeIndex(df_trading_pair):
df_trading_pair = df_trading_pair.set_index('Start Date', inplace=False)
# Rename the column names for best practices
df_trading_pair.rename(columns = { "Open Price" : 'Open',
"High Price" : 'High',
"Low Price" : 'Low',
"Close Price" :'Close',
}, inplace = True)
return df_trading_pair
# Create another df just to properly plot the data
df_trading_pair_date_time_index = set_DateTimeIndex(df_trading_pair)
</code></pre>
<h2>Script</h2>
<p>The following script will essentially plot a Japanese candlestick chart using the information stored in the <code>df_trading_pair</code> and <code>df_trading_pair_date_time_index</code> variables, the main details of such procedure are explained as comments within the script:</p>
<pre><code>import pandas as pd
import mplfinance as mpf
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
trading_pair = "SOLBUSD"
# Plotting
# Create my own `marketcolors` style:
mc = mpf.make_marketcolors(up='#2fc71e',down='#ed2f1a',inherit=True)
# Create my own `MatPlotFinance` style:
s = mpf.make_mpf_style(base_mpl_style=['bmh', 'dark_background'],marketcolors=mc, y_on_right=True)
# Plot it
# First create a dictionary to store the plots to add
subplots = {'Low SMA 9': mpf.make_addplot(df_trading_pair['Low SMA 9'], width=1, color='#F0FF42'),
'Close SMA 25': mpf.make_addplot(df_trading_pair['Close SMA 25'], width=1.5, color='#EA047E'),
'High SMA 99': mpf.make_addplot(df_trading_pair['High SMA 99'], width=2, color='#00FFD1')}
trading_plot, axlist = mpf.plot(df_trading_pair_date_time_index,
figratio=(10, 6),
type="candle",
style=s,
tight_layout=True,
datetime_format = '%H:%M',
ylabel = "Precio ($)",
returnfig=True,
show_nontrading=True,
addplot=list(subplots.values())
)
# Add Title
symbol = trading_pair.replace("BUSD","")+"/"+"BUSD"
axlist[0].set_title(f"{symbol} - 3m", fontsize=25, style='italic', fontfamily='fantasy')
# Find which times should be shown every 6 minutes starting at the last row of the df
x_axis_minutes = []
for i in range (1,len(df_trading_pair_date_time_index),2):
x_axis_minutes.append(df_trading_pair_date_time_index.index[-i].minute)
# Set the main "ticks" to show at the x axis
axlist[0].xaxis.set_major_locator(mdates.MinuteLocator(byminute=x_axis_minutes))
# Set the x axis label
axlist[0].set_xlabel('Zona Horaria UTC')
# Set the SMA legends
# First set the amount of legends to add to the legend box
axlist[0].legend([None]*(len(subplots)+2))
# Then Store the legend objects in a variable called "handles", based on this script, your objects to legend will appear from the third element in this list
handles = axlist[0].get_legend().legendHandles
# Finally set the corresponding names for the plotted SMA trends and place the legend box to the upper left corner of the bigger plot
axlist[0].legend(handles=handles[2:],labels=list(subplots.keys()), loc = 'upper left')
</code></pre>
<p>Finally, this script will produce the following image:</p>
<p><a href="https://i.stack.imgur.com/sxi4s.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sxi4s.png" alt="output1" /></a></p>
<h2>Problem</h2>
<p>When comparing the chart printed by my script against the chart displayed by Binance:</p>
<p><a href="https://i.stack.imgur.com/Ezn79.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ezn79.png" alt="gráfico de binance" /></a></p>
<p>It is evident that the largest moving average (the one of <code>99</code> value) was not plotted as such, or it was, but <em><strong>I think</strong></em> because of the size set (<code>figratio=(10, 6)</code>) for the same plot it ended up not appearing.</p>
<h2>The Question</h2>
<p>How could I make my script do a kind of <strong>Zoom out</strong> so that when printing the graph it shows the moving average of <code>99</code> without affecting the display of the other elements printed in the graph?.</p>

<p>I want to calculate the ratio of the <strong>upward, downward, and equal consistency</strong> of two consecutive months of data in two columns, and use it as an evaluation metric of the time series forecast results.

<p>I calculated the results for the sample data using the following function and code, note that we do not include the yellow rows in the calculation of the final ratio, because the <code>y_true_dir</code> for these rows is either <code>null</code> or <code>0</code>:</p>

74,176,588 | <p>Hello Im working on project using Kotlin (for the first time). My problem is i don't know how to get data "fullname" inside "data" list where one of the data inside the list also getting use for the condition, the name is "Role" to my RecyclerView in my Activity.</p>
<p>So i need show list "fullname" inside my RecyclerView where the "Role" is "Patient".</p>
<p>Here is the DataFileRecord:</p>
<pre><code>data class DataFileRecord(
@field:SerializedName("total")
val total: Int? = null,
@field:SerializedName("data")
val data: List<DataItem>? = null,
@field:SerializedName("offset")
val offset: Int? = null,
@field:SerializedName("limit")
val limit: Int? = null,
@field:SerializedName("status")
val status: Int? = null
)
//get fullname
data class DataItem(
@field:SerializedName("updateDate")
val updateDate: String? = null,
@field:SerializedName("departement")
val departement: Departement? = null,
@field:SerializedName("isBlock")
val isBlock: String? = null,
@field:SerializedName("role")
val role: Role? = null,
@field:SerializedName("fullname")
val fullname: String? = null,
@field:SerializedName("id")
val id: String? = null,
@field:SerializedName("username")
val username: String? = null
)
//get role = patient
data class Role(
@field:SerializedName("name")
val name: String? = null,
@field:SerializedName("id")
val id: String? = null
)
data class Departement(
@field:SerializedName("name")
val name: String? = null,
@field:SerializedName("id")
val id: String? = null
)
</code></pre>
<p>Here is my Adapter:</p>
<pre><code>class PatientAdapter(val context: List<DataItem>) : RecyclerView.Adapter<PatientAdapter.MyViewHolder>() {
var patientList: List<DataItem> = listOf()
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
val view = LayoutInflater.from(parent.context).inflate(R.layout.item_patient,parent,false)
return MyViewHolder(view)
}
override fun getItemCount(): Int {
return patientList.size
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int){
holder.patientName.text = patientList.get(position).fullname
}
@SuppressLint("NotifyDataSetChanged")
fun setPatientListItems(patientList: List<DataItem>){
this.patientList=patientList
notifyDataSetChanged()
}
class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val patientName: TextView = itemView.findViewById(R.id.itemPatientName)
}
}
</code></pre>
<p>And here is where i stuck with my Call api in my activity:</p>
<pre><code>//this 4 lines are inside oncreate
patientRecyclerView.setHasFixedSize(true)
linearLayoutManager = LinearLayoutManager(this)
patientRecyclerView.layoutManager = linearLayoutManager
patientRecyclerView.adapter = recyclerAdapter
fun getPatient(apiKey: String, apiSecret: String, token: String){
val retrofit = RetrofitClient.getClient()
retrofit.addGetPatient(apiKey,apiSecret,token)
.enqueue(object : Callback<DataFileRecord>{
override fun onResponse(call: Call<DataFileRecord>, response: Response<DataFileRecord>) {
TODO("Not yet implemented")
val dataPatient = response.body()
if (response.isSuccessful){
---------------- HERE WHERE I STUCK --------------------
}
}
override fun onFailure(call: Call<DataFileRecord>, t: Throwable) {
TODO("Not yet implemented")
}
})
}
</code></pre>

74,176,606 | <p>Sometimes when joining or matching with dates it does not matter if two dates are only a day or two apart. The most recent example occurred to me while using Quicken financial management software. Something got messed up in my Quicken reconciliation. I now have a table of transactions from Quicken and another table of transactions downloaded from my bank. I made one data.table from the two separate tables using <code>rbindlist</code>. I want to find which transactions have no counterpart in the other table. That would be easy if the dates matched as exactly as the number of dollars and cents. But sometimes the dates are off by 2 OR 3 OR 4 OR 5 days but not by 2 months. Using data.table or base R (or if I really must, tidyverse), how do I allow a match if the dates are only a few days off?</p>
<h1>example</h1>
<pre><code>rep.exmpl <- data.table(date = as.IDate(c("2022-10-23", "2022-10-23", "2022-10-20", "2022-10-20", "2022-10-15", "2022-10-12", "2022-10-05", "2022-10-01", "2022-09-30", "2022-08-05")), amount = c(10.00, 10.00, 1.53, 1.53, 78.00, 78.00, 89.56, 65.01, 65.01, 65.01), source = c("bank", "quicken", "bank", "quicken","bank", "quicken", "bank", "bank", "quicken", "quicken"))
rep.exmpl
</code></pre>
<p>rep.exmpl stands for "reproducible example".</p>
<pre><code> date amount source
1: 2022-10-23 10.00 bank
2: 2022-10-23 10.00 quicken
3: 2022-10-20 1.53 bank
4: 2022-10-20 1.53 quicken
5: 2022-10-15 78.00 bank
6: 2022-10-12 78.00 quicken
7: 2022-10-05 89.56 bank
8: 2022-10-01 65.01 bank
9: 2022-09-30 65.01 quicken
10: 2022-08-05 65.01 quicken
</code></pre>
<p>I used <code>fsetdiff</code> to see what was in one source but not the other.</p>
<pre><code>fsetdiff(x = rep.exmpl[source=="bank", .(date, amount)], y = rep.exmpl[source=="quicken", .(date, amount)])# in bank only
fsetdiff(x = rep.exmpl[source=="quicken", .(date, amount)], y = rep.exmpl[source=="bank", .(date, amount)])# in quicken only
</code></pre>
<p>Row 5 and 6 should be seen as the same since they are only 3 days apart and hence should not be shown to me as a transaction that appeared in only one source.
Row 7 should be shown to me since it only appears in bank. Row 10 should be shown to me since it is clearly a different instance to row 8 and 9 without anything matching it in bank. But that is not what happens. Some of it works but much does not.</p>
<h2>In bank only</h2>
<pre><code> date amount
1: 2022-10-15 78.00
2: 2022-10-05 89.56
3: 2022-10-01 65.01
</code></pre>
<p>Row 1 and 3 should not be shown.</p>
<h2>In Quicken only</h2>
<pre><code> date amount
1: 2022-10-12 78.00
2: 2022-09-30 65.01
3: 2022-08-05 65.01
</code></pre>
<p>Row 1 and 2 should not be shown. Only row 3 should be shown.</p>
<p>How would you solve this problem elegantly? I thought of trying to create a couple of columns +/- 7 days in the Quicken table and then using rolling joins (<code>roll = TRUE</code>) or perhaps fast overlap joins (<code>foverlaps</code>). One of my problems is that the fuzzy date match could be backwards or forwards.</p>

74,176,655 | <p>I'm getting <a href="https://i.stack.imgur.com/4oT6e.png" rel="nofollow noreferrer">weird numbers</a> on my C# sorting algorithm times that I <em>think</em> is caused by python recompiling the code every loop. How can I change this function to compile the C# code once and then execute the same compilation with different command line arguments? Is that even possible? In theory the code should follow a curve similar to the rest of the languages being tested.</p>
<pre><code>def runCSharp(debug):
for size in range(1000, 10001, 1000):
if debug:
print("Beginning to sort", size, " integers")
# Start the clock
tic = time.time()
# Run the C# script BubbleSort.cs in the CSharp folder
args = ['dotnet', 'run', str(size)]
p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, encoding='utf-8', cwd="CSharp")
output, err = p.communicate()
if debug:
print(output)
print(err)
print("C# Bubble Sort finished in %0.6f seconds" % (toc - tic))
toc = time.time()
csharpTimes.append(toc-tic)
return csharpTimes
</code></pre>
<p>For completeness's sake, this is my C# code, although it sorts fine and something besides my sort implementation is likely the culprit.</p>
<pre><code>using System;
using System.IO;
class BubbleSort
{
static void Main(string[] args)
{
int length;
StreamReader reader;
if (args.Length > 0)
{
length = Convert.ToInt32(args[0]);
reader = new StreamReader(@"..\numbers.txt");
}
else
{
length = 10000;
reader = new StreamReader(@"..\..\..\..\numbers.txt");
}
Console.WriteLine("Sorting {0} numbers (C#)", length);
int[] array = new int[length];
for (int i = 0; i < length; i++)
{
array[i] = Convert.ToInt32(reader.ReadLine());
}
bool sorted = false;
while (!sorted)
{
sorted = true;
for (int i = 0; i < length - 1; i++)
{
if (array[i] > array[i + 1])
{
int temp = array[i];
array[i] = array[i + 1];
array[i + 1] = temp;
sorted = false;
}
}
}
// Print the first and last ten numbers from the array to the console
for (int i = 0; i < 10; i++)
{
Console.WriteLine(array[i]);
}
for (int i = length - 10; i < length; i++)
{
Console.WriteLine(array[i]);
}
}
}

74,176,663 | <p>I have a function with five variables that I want to maximize using only an specific set of parameters for each variable.</p>
<p>Are there any methods in R that can do this, other than by brutal force? (e.g. Particle Swarm Optimization, Genetic Algorithm, Greedy, etc.). I have read a few packages but they seem to create their own set of parameters from within a given range. I am only interested in optimizing the set of options provided.</p>
<p>Here is a simplified version of the problem:</p>
<pre><code>#Example of 5 variable function to optimize
Fn<-function(x){
a=x[1]
b=x[2]
c=x[3]
d=x[4]
e=x[5]
SUM=a+b+c+d+e
return(SUM)
}
#Parameters for variables to optimize
Vars=list(
As=c(seq(1.5,3, by = 0.3)), #float
Bs=c(1,2), #Binary
Cs=c(seq(1,60, by=10)), #Integer
Ds=c(seq(60,-60, length.out=5)), #Negtive
Es=c(1,2,3)
)
#Full combination
FullCombn= expand.grid(Vars)
Results=data.frame(I=as.numeric(), Sum=as.numeric())
for (i in 1:nrow(FullCombn)){
ParsI=FullCombn[i,]
ResultI=Fn(ParsI)
Results=rbind(Results,c(I=i,Sum=ResultI))
}
#Best iteration (Largest result)
Best=Results[Results[, 2] == max(Results[, 2]),]
#Best parameters
FullCombn[Best$I,]
