74,160,293 | <p>I am trying to make the <code>header</code> element's height size to change depending on a criteria. I set the desired heights in a <code>headerHeightClass</code> inside a <code>computed</code> object but it doesn't seem to work.</p>

74,160,329 | <p>I'm pretty new to C# and I have a project coming up. Recently, I've created another dummy project just to get this fact down. I'm just trying to get the user to input their name and for it to be displayed. Here's what I've got so far, which of course is not working. Some help would be greatly appreciated, even if this seems like a very dumb or basic question.</p>
<pre class="lang-cs prettyprint-override"><code>public class Employee

set { firstName = value; }
}
public string GetNames()
{
Console.WriteLine("Please enter your first name:");
firstName = Convert.ToString(Console.ReadKey());
return firstName;
}
public Employee()
{
firstName = this.firstName;
}
public static void Display(string firstName)
{
Console.WriteLine(firstName);
}
}

74,160,333 | <p>I have an fileuploader that has preview images for the files to be uploaded. There are frontend and backend validations that prevent more than 10 files being submitted in one upload.</p>
<p>What I would like to do is have it so when more than 10 files are attached, the preview images for anything over the 10th image are removed from the image previews (there are error messages currently outputted too). I have separate functionality regarding the actual FileList of files form the input element, but should be able to get the solution to work for both.</p>
<p>Below is a minimal code representation of the problem. If required I can show the full file uploader code, but there is quite a lot of code unrelated to this issue which may be confusing.</p>
<pre><code>// Generate a preview <img> for each selected file
// the submitData.files array is generated from a change event listener on a file input elment
[...submitData.files].forEach(showFiles);
});
function showFiles(file) {
let previewImage = new Image();
previewImage.className = "img upload-preview-image";
previewImage.src = URL.createObjectURL(file);
// use decode() method that waits for individual preview images to be added when running validations
previewImage.decode().then((response) => {
// validations happen here for each image as part of the showFiles() function called in the forEach loop above
let imgList = document.querySelectorAll('.upload-preview-image'), // redeclare under new var name inside promise
if (imgList.length > 10) {
/*** somehow remove all images from the imgList array after the 10th image,
either by deleting them or exiting this function when the 10th item is added ***/
}
}).catch((encodingError) => {
// Do something with the error.
});
}

74,160,344 | <p>I've spent hours on this one, and I'm still stuck. And the really baffling thing is, according to the Lua documentation, I shouldn't even be having this problem:</p>
<p><a href="https://www.lua.org/manual/5.1/manual.html#2.2.1" rel="nofollow noreferrer">https://www.lua.org/manual/5.1/manual.html#2.2.1</a></p>
<p>I've got the following Lua script:</p>
<pre><code>local takevol = tn(chunk:match("VOLPAN%s%d%s%d%s([+-]?%d*%.?%d*)"))
newchunk = string.gsub(chunk,"(\n%s*PT%s%d%s)([+-]?%d*%.?%d*)","%1"..takevol*tonumber("%2"))
</code></pre>
<p>The source I am working with is an item data chunk (string format) that looks like this (truncated for brevity):</p>
<pre><code>VOLPAN 1 0 15.848932 -1
SOFFS 365.84808854166607
PLAYRATE 0.25 0 0 -1 0 0.0025
CHANMODE 3
GUID {79C49752-9C32-D545-A54E-8CFFF9ACC14E}
<VOLENV
EGUID {92E4F259-A31C-0E49-81CB-B2C1ABA21CD4}
ACT 1 -1
VIS 1 1 1
LANEHEIGHT 0 0
ARM 0
DEFSHAPE 0 -1 -1
VOLTYPE 1
PT 0 1 0
>
>
</code></pre>
<p>Basically, I'm trying to get the volume value from the line starting <code>VOLPAN</code> (15.848932), multiply that with each second number captured from the lines starting <code>PT</code>, replacing the second number value in each <code>PT</code> line with the result, which, for this example, would come out like this:</p>
<pre><code>VOLPAN 1 0 15.848932 -1
SOFFS 365.84808854166607
PLAYRATE 0.25 0 0 -1 0 0.0025
CHANMODE 3
GUID {79C49752-9C32-D545-A54E-8CFFF9ACC14E}
<VOLENV
EGUID {92E4F259-A31C-0E49-81CB-B2C1ABA21CD4}
ACT 1 -1
VIS 1 1 1
LANEHEIGHT 0 0
ARM 0
DEFSHAPE 0 -1 -1
VOLTYPE 1
PT 0 15.848932 0
>
</code></pre>
<p>In this example, there is just one <code>PT</code> line. For some item chunks, there are dozens, which is why I chose gsub to iterate through them. And ultimately, I'll be processing anywhere from a few dozen to <em><strong>thousands</strong></em> of these items at a time.</p>
<p>Please help me. I'm really at a total loss on how to get the captured value from the <code>PT</code> lines into a number format that I can do the multiplication with. I've looked through Lua documentation, read through several semi-related forum posts/questions, and I've experimented with different ways of escaping the variable for the capture, trying to use a function and do the math outside of the gsub command, and a number of other things. But I still just keep getting errors, typically either "attempt to perform arithmetic on a nil value" or "attempt to perform arithmetic on a string value".</p>
<p>And, of course, based on the following excerpt from the manual (as linked above), it seems like performing arithmetic on a string value should normally work just fine in Lua.</p>
<blockquote>
<p>Lua provides automatic conversion between string and number values at
run time. Any arithmetic operation applied to a string tries to
convert this string to a number, following the usual conversion
rules.</p>

74,160,353 | <p>Matrix multiplication Y = A * B can be implemented by mul!(Y, A, B) to save on memory allocations. But mul! can't be used if Y = A. Is there a similarly efficient way to calculate Y *= B? Or if not, what is the most efficient way to do matrix multiplication Y *= B</p>
<p>Small working example:</p>
<pre><code>n = 10
A = rand(n,n)
B = rand(n,n)
Y = zeros(n,n)
#mul! removes allocations
@allocated Y = A * B #896
@allocated mul!(Y, A, B) #0
#mul! can't be applied in this case
@allocated Y *= B #896
#desired function performance
@allocated mul_2!(Y, B) #0

74,160,442 | <p>This goes back to a question I've asked some time ago - I'm still struggling in the same area.</p>
<p>I have a data.table with some values ('value'), lower limits ('min_val') and upper limits ('max_val'):</p>
<pre><code> | value | min_val | max_val |
1: | 94.001 | 94.00 | 94.02 |
2: | 94.002 | 94.00 | 94.03 |
3: | 94.003 | 94.01 | 94.04 |
4: | 95 | 94.98 | 95.02 |
5: | 100.00 | 99.00 | 101.00 |
6: | 100.10 | 99.10 | 101.00 |
7: | 200.00 | 199.00 | 201.00 |
8: | 200.10 | 199.00 | 201.00 |
</code></pre>
<p>With your help I have the count:</p>
<pre><code> | value | min_val | max_val | count | id |
1: | 94.001 | 94.00 | 94.02 | 1 | 1 |
2: | 94.002 | 94.00 | 94.03 | 2 | 2 |
3: | 94.003 | 94.01 | 94.04 | 2 | 2 |
4: | 95 | 94.98 | 95.02 | 1 | 3 |
5: | 100.00 | 99.00 | 101.00 | 2 | 4 |
6: | 100.10 | 99.10 | 101.00 | 2 | 4 |
7: | 200.00 | 199.00 | 201.00 | 2 | 5 |
8: | 200.10 | 199.00 | 201.00 | 2 | 5 |
</code></pre>
<p>Now I want to uniquely identify (col id) each "count group" so that I can use the identified later on (by=id).
I've tried calculating the mean of 'value' column hoping I'll get unique identifiers but the mean function returns 1/count. Not sure how to proceed - I'm stuck as I don't understand how to "go backwards" while doing the computations (example: for 94.003, I need to compare the next element of column value to it and also the previous element):</p>
<pre><code>dat[, count := mapply(function(mi,ma) mean(mi < value & value < ma), min_val, max_val)]
</code></pre>
<p>input:</p>
<pre><code> library(data.table)
dat <- setDT(structure(list(value = c(94.01, 94.02, 94.03, 95, 100, 100.1, 200, 200.1), min_val = c(94, 94, 94.01, 94.98, 99, 99.1, 199, 199), max_val = c(94.02, 94.03, 94.04, 95.02, 101, 101, 201, 201)), class = c("data.table", "data.frame"), row.names = c(NA, -4L)))
dat[, count := mapply(function(mi,ma) sum(mi < value & value < ma), min_val, max_val)]
</code></pre>
<p>I'm struggling with this for a few days. The only thing I could think of is that I need to modify the method that does the count so that I do the marking the same way. I did not find a solution. I use this method to generate the count</p>
<pre><code>dat[, count := mapply(function(mi,ma) sum(mi < value & value < ma), min_val, max_val)]
</code></pre>

74,160,451 | <p>I created a frosted AppBar has a SafeArea wrapping. I want a scrollview that scrolls under it, but i'm unable to code a variable padding that adds the SafeArea of the AppBar to the top padding of the SingleChildScrollView. Does anyone have any tips?

<pre><code>home: Scaffold(
backgroundColor: const Color(0xFFF6FFF1),
extendBody: true,
extendBodyBehindAppBar: true,
// Body
body: SingleChildScrollView(
padding:
EdgeInsets.only(top: 90, left: 10, right: 10, bottom: 8),
child: Text(
lorem(paragraphs: 4, words: 480),
),
),
appBar: FrostedAppBar(
actions: [

icon: Icon(
Icons.help_outline_rounded,
color: lightColorScheme.tertiary,

74,160,495 | <p>I remember working on a project made in Django where you could create routes that could be given a prefix and then include another URL file for the rest of the endpoint.</p>
<pre class="lang-py prettyprint-override"><code>api_patterns= [
url('foo/', include(foo.urls)),
url('bar/', include(bar.urls)),
]
urlpatterns = [
url(r'api/', include(api_patterns)),
]
</code></pre>
<p>This implementation would result in endpoints <code>/api/foo/</code> and <code>/api/bar/</code> and these endpoints would live in separate directories with separate url files.</p>
<h1>The question is whether we can implement something equivalent to <strong>Spring Boot</strong>.</h1>
<p>I know you can add the prefix to the <code>@RequestMapping</code> on all the files.
But in my current project, we have a lot of controllers that start from the same route prefix and then, later on, differ from each other.</p>
<pre class="lang-java prettyprint-override"><code>// Foo controller
@Controller
@RequestMapping(path = "api/foo")
public class FooController {
@GetMapping(path = "")
// Endpoint to /api/foo
}
// Bar controller
@Controller
@RequestMapping(path = "api/bar")
public class BarController {
@GetMapping(path = "")
// Endpoint to /api/bar
}
// Tar controller by foo
@Controller
@RequestMapping(path = "api/foo/tar")
public class TarController {
@GetMapping(path = "")
// Endpoint to /api/foo/tar
}
</code></pre>
<p>The endpoint would then look like this <code>/api/foo</code>, <code>/api/bar</code>, and <code>/api/foo/tar</code>.</p>
<p>How can I prevent the repeated path prefix on all the files?</p>
<p><em>This routing might be a bad practice for working with API endpoint, I also think that this could be prevented, and that is why I'm asking as a junior developer to try to improve and show responsibility at my first job.</em></p>

74,160,509 | <p>I'm trying to print the last message from WinApi to the console. Sounds simple, or so I thought. I made this simple enough function, but I'm getting an error code 8 (ERROR_NOT_ENOUGH_MEMORY). I'm not sure how this could be. I didn't find anything online either. Here's what I've got:</p>
<pre><code>static inline void printLastMessage()
{
LPTSTR lpMsgBuf;
if(FormatMessage((FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_IGNORE_INSERTS), NULL,
GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), lpMsgBuf, 0, NULL) == 0)
{
printf("Error Code: %d\n", GetLastError());
}
wprintf(L"Error: %s\n", lpMsgBuf);
LocalFree(lpMsgBuf);
}
</code></pre>
<p>The resulting buffer looks like this in the console:</p>
<pre><code>Error: (null)
</code></pre>
<p>I've also tried FormatMessageW, but it didn't make a difference. (And it seems like FormatMessage is defined as FormatMessageW with UNICODE)</p>
<p>I'm using MinGW's GCC with C11, Windows SDK 10.0.22621.</p>
<p>Edit: Updated (LPTSTR)&lpMsgBuf. Current code:</p>
<pre><code>static inline void printLastMessage()
{
LPTSTR lpMsgBuf;
DWORD err = GetLastError();
printf("Error code: %d\n", err);
if(FormatMessage((FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_IGNORE_INSERTS), NULL,
err, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL) == 0)
{
printf("Error Code (FormatMessage): %d\n", GetLastError());
}
wprintf(L"Error: %s\n", lpMsgBuf);
LocalFree(lpMsgBuf);
}
</code></pre>
<p>And output:</p>
<pre><code>Error code: 87
Error:

74,160,637 | <p>I am writing a text based adventure game in a batch file.</p>
<p>Long story short, I want the program to convert a sentence the user types into the game from the first person into the second person, by simply replacing singular pronouns such as 'I' with 'You.'</p>
<p>So a person says: I search inside the box.
The program says: You search inside the box.</p>
<p>For this I'm using this script where 'choice' contains the user's entry.</p>
<pre><code>set choice=%choice:i=you%
set choice=%choice:we=you%
set choice=%choice:us=you%
set choice=%choice:my=your%
set choice=%choice:myself=yourself%
set choice=%choice:ourselves=yourselves%
set choice=%choice:am=are%
set choice=%choice:I'm=you're%
set choice=%choice:I am=you are%
</code></pre>
<p>However, every instance of 'I' is replaced.
So when you type: I search inside the box.
You get: You search younsyoude the box.</p>
<p>How do I tell the program to only replace an exact phrase (including spaces.)
I want to try and avoid using powershell if at all possible. Otherwise, I'm not opposed to ideas.</p>

74,160,804 | <p>I have a dataframe in pandas that originally had a parsed date column with values such as: <code>2020-05-11 02:23:00</code>. <br></p>
<p>From that I created a 'Date' column using <code>df['Date'] = df.parsed_date_column.dt.date</code> producing values eg <code>2020-05-11</code> with datatype 'object'. <br></p>
<p>From there I wanted to only retain the rows from a certain date, i.e. <code>df.loc[df['Date'] == '2021-06-26']</code> or more simply <code>df[df['Date'] == '2021-06-26']</code>. <br>
Whenever I execute this, it returns an empty dataframe with no rows and only the column names. <br></p>
<p>I have tried converting it to datetime64:<code>pd.to_datetime(df['Date'], format='%Y-%m-%d')</code>, <br>
specify the object as a string: <code>combined_lanes[~combined_lanes['Date'].str.contains("2021-06-20")]</code>, <br> and defining the date seperately:</p>
<pre><code>date = "2021-06-20"
df = df[df['Date'].str.lower() == date]
</code></pre>
<p>Nothing I've tried or researched works.</p>
<p>Note: this does not occur when I try other columns, including ones with the datatype 'object'.</p>

<p>What I am trying to achieve is getting the break times in a new object like so:</p>
<pre><code> const ELEMENT_DATA: Breaks[] = [
{day: 'Tuesday', start: '12:00', end: '12:30'},
{day: 'Tuesday', start: '13:30', end: '13:50'},
{day: 'Wednesday', start: '12:00', end: '12:30'},
{day: 'Wednesday', start: '13:30', end: '13:50'},
...... etc....
];
</code></pre>
<p>What is the best way to do so?
I'm pretty new to javascript and typescript, getting a little confused on how to iterate over this object that has nested objects within.</p>
<p>If you have the answer could you please also explain how your code works to give me a better understanding?
Much appreciated guys!</p>

74,160,902 | <p>Edit: The following is a simplified code of a more complex example.</p>
<pre><code>def lottery(amount, callback=None):
print(f'You spent {amount} on a lottery ticket.')
if callback:
callback(amount)
def win(amount):
print(f'You won ${amount * 1000}!!!')
def lose(amount):
print(f"Sorry, you spent {amount} and didn't win anything.")
</code></pre>
<p>Edit: The 'lottery' function is from a third-party package. I would prefer not to modify their code.</p>
<p>The following works, but they aren't what I am looking for.</p>
<pre><code>lottery(100, win)
</code></pre>
<p>Output:</p>
<p>You spent 100 on a lottery ticket.
You won $100000!!!</p>
<pre><code>lottery(100, callback=win)
</code></pre>
<p>Output:</p>
<p>You spent 100 on a lottery ticket.
You won $100000!!!</p>
<pre><code>lottery(100, lose)
</code></pre>
<p>Output:</p>
<p>You spent 100 on a lottery ticket.
Sorry, you spent 100 and didn't win anything.</p>
<pre><code>lottery(100, callback=lose)
</code></pre>
<p>You spent 100 on a lottery ticket.
Sorry, you spent 100 and didn't win anything.</p>
<p><strong>What I'm looking for is to continue to use a callback and have a variable hold a value of either 'win', 'lose', [Edit: or additional functions like 'win_1', 'win_2', ..., 'win_n' or 'lose_1', 'lose_2', ..., 'lose_n'] and use that variable in the same place as the callback name.</strong></p>
<p>Wishful example:</p>
<pre><code>win_lose = 'win'
lottery(100, win_lose)
</code></pre>
<p>Edit: the string 'win' is built on the fly like:</p>
<pre><code>'win' + '_' + str(index)
</code></pre>
<p>or</p>
<pre><code>'lose' + '_' + str(index)
</code></pre>
<p>Wishful output:</p>
<p>You spent 100 on a lottery ticket.
You won $100000!!!</p>

74,160,932 | <p>I'm trying to find the number of numbers divisble by 2 in 0-100, I have used a range() function and n1=n1+1 to generate 0 to 100, then with an if statement display only numbers wholely divisble by 2.</p>
<p>For the life of me I cannot find a way to count the number of times 0's are printed in the console, I googled count() but that seems to work for opening other files not the one you are in.</p>
<pre><code>n1 = 1
for x in range(100):
dTwo = n1 % 2
if (int(dTwo) == 0):
print(n1)
n1 = n1 + 1 #generates 0 to 101
#how to I keep track of the number of 0s outputted in console after this step?

74,160,957 | <p>Alright, this is a very basic question, but I'm not seeing the fix here. I want to flatten an array that has one layer of depth and at the same time multiply each element by 2. However, when I run flat map on arr1 the console is returning NaN instead of an array of 5 elements with each element being multiplied by 2. Code example below:</p>
<p>const arr1 = [ [2,5] , [5,10,15] ];</p>
<p>const arr2 = arr1.flatMap((el) => el * 2);</p>
<p>console.log(arr2);</p>
<p>Expected // [4, 10, 10, 20, 30]</p>
<p>Actual // [Nan, Nan]</p>
<p>If I run the flatMap without the multiplication I get the array with each element but it's only once I try to mulitply each value that I get the two NaN. What am I missing?</p>
<p>const arr3 = arr1.flatMap((el) => el);
console.log(arr3);</p>
<p>Actaul // [2,5,5,10,15];</p>

74,161,038 | <p>I have a dataset and am building a shiny flexdashboard with multiple user inputs which filter the data down to a subset. I am struggling with just one of the filters, where if the user chooses 'ALL' in <code>selectInput</code>, I want that filter function not to do anything and just return the data as is. Below is one of my attempts:</p>
<pre><code>library(flexdashboard)
library(DT)
library(lubridate)
library(readr)
library(tidyverse)
...
qry <- read_file("some_query.sql")
Data_df <- con %>% tbl(sql(qry)) %>% collect()
doctors_to_choose <- unique(pull(Data_df, 'Doctor')) %>%append('ALL')
Column {data-width=200 .sidebar}
-----------------------------------------------------------------------
```{r}
checkboxGroupInput("drug_classes",
label = "Choose the classes of drugs",
choices = c("II", "III", "IV", "V"),
selected = c("V"),
)
selectInput(
inputId="chosen_doctor",
label="Choose Doctor",
choices=doctors_to_choose,
selected = "ALL",
multiple = FALSE,
size = NULL
)
show_data_df <- reactive({
Data_df %>%
filter(`Drug Class` %in% input$drug_classes) %>%
{if (input$chosen_doctor != "ALL") filter(Doctor == input$chosen_doctor )
else filter(`Drug Class` %in% input$drug_classes) }
} )
```
</code></pre>
<p>I tried to use an if-else statement as above but failed. because In the original code, I have a long list of filters applied so ideally I would like to use something that does not require me to retype all the previous filters/actions like I did in the else part above.</p>

74,161,204 | <p>I am trying to join two datasets, but they are not the same or have the same criteria.</p>
<p>Currently I have the dataset below, which contains the number of fires based on month and year, but the months are part of the header and the years are a column.</p>
<p><a href="https://i.stack.imgur.com/xCzJ5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xCzJ5.png" alt="enter image description here" /></a></p>
<p>I would like to add this data, using as target data_medicao column from this other dataset, into a new column (let's hypothetically call it nr_total_queimadas).</p>
<p><a href="https://i.stack.imgur.com/oV7g0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oV7g0.png" alt="enter image description here" /></a></p>
<p>The date format is YYYY-MM-DD, but the day doesn't really matter here.</p>
<p>I tried to make a loop of this case, but I think I'm doing something wrong and I don't have much idea how to proceed in this case.</p>
<p>Below an example of how I would like the output with the junction of the two datasets:</p>
<p><a href="https://i.stack.imgur.com/6NQEz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6NQEz.png" alt="enter image description here" /></a></p>
<p>I used as an example the case where some dates repeat (which should happen) so the number present in the dataset that contains the number of fires, should also repeat.</p>

74,161,233 | <p>When we are iterating in reverse direction, I see that most people use the following structure:</p>
<pre><code>for (auto it = vec.rbegin(); it != vec.rend(); it++)
{
// block of code //
}
</code></pre>
<p>But for a long time, I have a doubt about using this, and I want to know why the following code does not work.</p>
<p>As we know, the last element will have the highest index than any element index in the array, and the array is going to take contiguous memory.</p>
<p>My primary doubt is when iterating backwards, why shouldn't we use <code>it--</code>?</p>
<p>I want the reason why the following code is not going to work. I am running the loop from <code>rbegin</code>, that is the last element, and I am going until the first element. I am decrementing <code>it</code> by one in every iteration.</p>
<pre><code>for (auto it = vec.rbegin(); it >= vec.begin(); it--)
{
cout << *it << endl;
}

74,161,273 | <p>Is there a way to use javascript to select a link that only has an href and rel. I am trying to use the console to select a link, but the link in particular has no ID. I've tried the .click function but it seems that only works for buttons.</p>

74,161,274 | <p>I have a microservice project. I am using DRF. Now I need to add notification system to this project. Since we have multiple service notification can come from any service. We also have web version and mobile version in frontend.
Which will be better option for notification service? Notification with firebase or Notification with celery?</p>

74,161,318 | <p>So I'm trying to practice c# and stumbled with the connection error, I already stated that my connection will be closed but it tells me that my connection is still open. I really have no idea what's wrong with this.</p>
<pre><code>public void getdept()
{
con.Open();
string query = "SELECT * FROM positions where PositionName=" + cbxposname.SelectedValue.ToString() + "";
SqlCommand cmd = new SqlCommand(query, con);
DataTable dt = new DataTable();
SqlDataAdapter sda = new SqlDataAdapter(query, con);
sda.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
txtdeptname.Text = dr["Department"].ToString();
}
con.Close();
}
</code></pre>
<p>Any tips is welcomed!</p>

74,161,322 | <p>This query has so many joins and i have to apply conditions on joined table columns to get the desired results but query becomes slow when i apply condition on a <code>datetime</code> column.</p>
<p>Here is the query</p>
<pre class="lang-sql prettyprint-override"><code> select
distinct v0_.id as id_0,
MIN(v4_.price) as sclr_4

and (v0_.deleted_at is null)
and c13_.start_at >= '2022-10-21 19:00:00' --- this slows down the query
group by

</code></pre>
<p>And here is the query plan <a href="https://explain.dalibo.com/plan/46h0fb3343e246a5" rel="nofollow noreferrer">https://explain.dalibo.com/plan/46h0fb3343e246a5</a>.
The query plan is so big that i cannot paste it here</p>
<p>Plain query plan <a href="https://explain.depesz.com/s/7qnD" rel="nofollow noreferrer">https://explain.depesz.com/s/7qnD</a></p>
<p>Plain query plan without where condition <a href="https://explain.depesz.com/s/3sK3" rel="nofollow noreferrer">https://explain.depesz.com/s/3sK3</a></p>
<p>The query shouldn't take much time as there are not many rows in tables.</p>
<ul>
<li>calendar_entry table has ~350000 rows</li>
<li>venue_item_price table has also ~320000 rows</li>

74,161,327 | <p>I am trying to coded a Pix2Pix GAN but I am getting this error with my Data loader:</p>
<pre><code>Caught TypeError in DataLoader worker process 0.
</code></pre>
<p>here is my dataset class:</p>
<pre><code>class Pix2PixDataset(Dataset):
def __init__(self, data_points, transforms = None):
self.data_points = data_points
self.transforms = transforms
self.resize = T.Resize((512,512))
def __getitem__(self, index) :
image = self.resize(read_a_image(self.data_points[index].reference_image))
y_label = self.resize(read_a_image(self.data_points[index].drawing))
if self.transforms:
image = self.transforms(image)
y_label = self.transforms(y_label)
return(image, y_label)
def __len__(self):
return len(self.data_points)
</code></pre>
<p>and here is the code for my dataloader:</p>
<pre><code>test_loader2 = DataLoader(traindataset, batch_size=Batch, shuffle=True, num_workers = Num_Workers, collate_fn = transforms.RandomRotation(degrees=360), pin_memory=True)
for test_images, test_drawing in test_loader2:
display(test_images)
plt.show()
display(test_drawing)
break
</code></pre>
<p>again I am doing a Pix to Pix so both my x and y(label) has to be an images tensor.
How can I do this ?
I saw on this site but that someone else got this same error and they was told that y has to be an int, but again I am doing a Pix2Pix gans so both my x and y are images
so how do I do this?</p>

74,161,332 | <p>I have a table with 3 rows.
<strong>| id | fullname | email.</strong><br>
In the php code, I have programmed that when someone registers on my site, it can be in active <strong>(y)</strong> or pending <strong>(t)</strong> status.<br><br>
What I want is to have a button called PENDING and when I press it, it will show only the users who are Pending in blue.
Now as it is, the pending users is blue without pressing the button.
Any idea; Thank you in advance..</p>

74,161,394 | <p>I have try to do all combination by matrix columns by R as below
Firstly, I have a 4*3 matrix as below</p>
<pre><code>> a
[,1] [,2] [,3] [,4]
[1,] 1 0 1 1
[2,] 1 0 0 0
[3,] 1 1 1 1
</code></pre>
<p>then we want to list total 3<em>1</em>2*2 = 12 combination, such as example below
one of example is</p>
<pre><code> [,1] [,2] [,3] [,4]
[1,] 1 0 1 1
[2,] 0 0 0 0
[3,] 0 1 0 0
</code></pre>
<p>and the second example is</p>
<pre><code> [,1] [,2] [,3] [,4]
[1,] 1 0 1 0
[2,] 0 0 0 0
[3,] 0 1 0 1
</code></pre>
<p>one column with only one number.
Currently, I already list down each column type, such as</p>
<pre><code>> whole.combination
[[1]]
b b b
[1,] 1 0 0
[2,] 0 1 0
[3,] 0 0 1
[[2]]
b
[1,] 0
[2,] 0
[3,] 1
[[3]]
b b
[1,] 1 0
[2,] 0 0
[3,] 0 1
[[4]]
b b
[1,] 1 0
[2,] 0 0
[3,] 0 1
</code></pre>
<p>however, although i can using cbind by manual to generate one</p>
<pre><code>> cbind(a[[1]][,1],a[[2]][,1],a[[3]][,1],a[[4]][,1])
[,1] [,2] [,3] [,4]
[1,] 1 0 1 1
[2,] 0 0 0 0
[3,] 0 1 0 0
</code></pre>
<p><strong>how can i combine each column by each matrix to generate one 4*3 matrix?</strong>
but, does it have any efficient way to list all combination in once?
therefore, if i extend this problem by n*m matrix, i need one algorithm to generate those matrix combination.
thanks</p>

74,161,395 | <p>Disclaimer: Über-noob.</p>
<p>This question may have more to do with how files are executed than what http or node do. I have the following simple-as-all-hell file that will be executed with node to make a local server.</p>
<pre><code>const http = require("http");
const hostname = "127.0.0.1";
const port = 8000;
// Create http server
const server = http.createServer( function (req,res) {
// set response http header with http status and content type
res.writeHead(200, {"Content-Type": "text/plain"});
// send response "hello world"
res.end("G'day mate\n");
});
// Listen on a given port and print a log when it starts listening
server.listen(port, hostname, () => {
console.log("heyy maattteeeyyy")
});
</code></pre>
<p>My question: Why, when I enter the command <code>node hello.js</code> does this file <em>keep executing</em> / keep running? I presume it is something about the final <code>server.listen()</code> command that says "when you run this, just keep running, I am now hosting something", but what exactly is that?</p>
<p>Edit: I would greatly appreciate detailed and exact explanations -- I am just learning, but the purpose of the question is to understand <em>exactly</em> what is going on.</p>
<p>Thank you</p>

74,161,399 | <p>I have a React component that only expects some values, but I've been passing objects to components a lot regardless of whether the properties of those objects are used in the component or not.</p>
<p>Here is the code example I mean where I pass the <code>Post</code> object to the <code>Title</code> component, that means I also pass the <code>comments</code> even though the <code>Title</code> component doesn't need it.</p>
<pre><code>type Post = {
title: string;
comments: Comment[];
};
function Title({ post }: { post: Post }) {
return <h1>{post.title}</h1>;
}
function Post(post: Post) {
return (
<div>
{/* here: */}
<Title post={post} />
{/* .... */}
</div>
);
}
</code></pre>
<p>And here I just passed the title to the <code>Title</code> component.</p>
<pre><code>type Post = {
title: string;
comments: Comment[];
};
function Title({ title }: { title: string}) {
return <h1>{title}</h1>;
}
function Post(post: Post) {
return (
<div>
{/* here: */}
<Title title={post.title} />
{/* .... */}
</div>
);
}

<p>What I want to ask is which one should I use better?</p>

74,161,558 | <p>The question below is an extension of <a href="https://stackoverflow.com/questions/74135095/adding-a-column-to-the-data-that-looks-for-a-list-of-words-and-adds-them-if-foun">this question</a>.</p>
<h1>Example data</h1>
<p>I have example data as follows:</p>
<pre><code>library(data.table)
example_dat <- fread("var_nam description
some_var this_is_some_var_kg
other_var this_is_meters_for_another_var
extra_var the_price_of_apples
another_var cost_of_goods_sold")
example_dat$description <- gsub("_", " ", example_dat$description)
var_nam description
1: some_var this is some var kg
2: other_var this is meters for another var
3: extra_var the price of apples
4: another_var cost of goods sold
vector_of_units <- c("kg", "meters", "var")
</code></pre>
<h1>Previous solutions</h1>
<p>I first asked how to create a separate column in this data which looks for certain units listed in a vector (<code>vector_of_units</code>). One option is to <a href="https://stackoverflow.com/a/74135271/8071608">use this answer by maydin</a>. Which gets out all matches.</p>
<pre><code>library(tidyverse)
setDT(example_dat)[, unit := unlist(lapply(example_dat$description,function(x)
paste0(vector_of_units[str_detect(x,vector_of_units)],
collapse = ",")))]
var_nam description unit
1: some_var this is some var Kg kg,var
2: other_var this is meters for another var meters,var
3: extra_var the Price of apples
4: another_var cost of goods sold
</code></pre>
<p>I also found <a href="https://stackoverflow.com/a/71280592/8071608">this answer by langtang</a>, which gets out the first match (which is actually preferable in my situation):</p>
<pre><code>example_dat[, unit:=stringr::str_extract(description, paste0(vector_of_units,collapse = "|"))]
var_nam description unit
1: some_var this is some var kg var
2: other_var this is meters for another var meters
3: extra_var the price of apples <NA>
4: another_var cost of goods sold <NA>
</code></pre>
<p><a href="https://stackoverflow.com/questions/71280466/based-on-vector-of-strings-extract-string-from-data-table-column-into-new-column">Based on vector of strings extract string from data.table column into new column</a></p>
<h1>More flexibility with an ifelse statement</h1>
<p>I would however like to have a little more flexibility.</p>
<p>Firstly, I would like to supply a vector of matches and a vector for pasting separately, so that I can change the hits in to something else:</p>
<pre><code>vector_of_units_in <- c("kg", "meters", "var")
vector_of_units_out <- c("kilogram", "meters", "variable")
vector_of_units_euro <- c("cost", "price")
vector_of_units_euro_out <- "euro"
</code></pre>
<p>Secondly, I would like to be able to choose what happens when there is no hit. For example, when applying the solution by langtang, I want it to not overwrite the first variables with <code>NA</code>.</p>
<p>I have been trying to mess around with langtang's solution:</p>
<pre><code>setDT(example_dat)[, unit := ifelse(!is.na(stringr::str_extract(description, vector_of_units_in)), paste0(vector_of_units_out, collapse = "|"), NA)]
# NA has been replaced by unit, so that it is not overwritten in case of no match
setDT(example_dat)[, unit := ifelse(!is.na(stringr::str_extract(description, vector_of_units_euro)), paste0(vector_of_units_euro_out, collapse = "|"), unit)]
</code></pre>
<p>But I end with this:</p>
<pre><code> var_nam description unit
1: some_var this is some var kg kilogram|meters|variable
2: other_var this is meters for another var kilogram|meters|variable
3: extra_var the price of apples <NA>
4: another_var cost of goods sold <NA>
</code></pre>
<p>How should I write this syntax?</p>
<h1>Desired output</h1>
<pre><code> var_nam description unit
1: some_var this is some var Kg kilogram
2: other_var this is meters for another var meters
3: extra_var the Price of apples euro
4: another_var cost of goods sold euro
</code></pre>

<p>I found in this question solutions to find out the sessions locked the table then kill the session but the table inserts each seconds a lot of results from interface sessions because this table interfaced with laboratory instruments and the machines insert laboratory results from the interface always ,</p>

74,161,611 | <p>I'm trying to find any number of <em><strong>words</strong></em> at the beginning or end of a string with a maximum of 20 characters.</p>
<p>This is what I have right now:</p>
<pre><code>s1 = "Hello, World! This is a reallly long string"
match = re.search(r"^(\b.{0,20}\b)", s1)
print(f"'{match.group(0)}'") # 'Hello, World! This '
</code></pre>
<p>My problem is the extra space that it adds at the end. I believe this is because \b matches either the beginning or the end of the string but I'm not sure what to do about it.</p>
<p>I run into the same issue if I try to do the same with the end of the string but with a leading space instead:</p>
<pre><code>s1 = "Hello, World! This is a reallly long string"
match = re.search(r"(\b.{0,20}\b)$", s1)
print(f"'{match.group(0)}'") # ' reallly long string'
</code></pre>
<p>I know I can just use rstrip and lstrip to get rid of the leading/trailing whitespace but I was just wondering if there's a way to do it with regex.</p>

Do you have some recommend for random these string to make sure it will be unique?</p>

Did some changes in the test branch and am ready to merge it into the main branch. But before merging I need to get other changes made by another user to develop the branch and keep mine. Only after it, I can merge the test to the main.</p>
<p>Precondition: 2 branches main and develop</p>
<p>Step 1: create new branch develop -> test</p>
<p>Step 2: add some code to test branch</p>

<p>When a user opens the workbook that you’ve shared your workbook with

</blockquote>
<p>Does RLS not apply when an excel file is shared with another user?</p>
<p>For exmaple: suppose I have RLS to restrict myself only to see country A. But if person having access to country B opens the analyze in excel report and saves this and shares it to me, then will I see country B even though I don't have access to country B?</p>
<p>Ofcourse if I refresh it will only show me country A based on my RLS.</p>

74,161,763 | <p>When creating a checkout session, I am providing line items with <code>price_data</code> and <code>quantity</code> and in the checkout I see the correct amount. For some payments the customer can use their in-app points which will reduce some amount from the total checkout amount. How can I apply that to the checkout?</p>
<p>Example:<br />
You buy 3 T-shirts (3x20) and one cap (1x15) which means you need to pay 75.00 (of some unit)<br />
You use the in-app option to use your points which gives you 5.00, so now your checkout session must be a custom value (70.00).</p>
<p>I am using this API:<br />
<a href="https://stripe.com/docs/api/checkout/sessions/create" rel="nofollow noreferrer">https://stripe.com/docs/api/checkout/sessions/create</a></p>
<p>The only solution that I came up with was to create a <a href="https://stripe.com/docs/api/coupons" rel="nofollow noreferrer">coupon</a> right before creating the checkout and apply it to the checkout, but I don't know if that's safe.</p>

74,161,800 | <p>Write a function that expects two lists of integers, a and b, as parameters and returns a list. The function should merge the elements of both input lists by index and return them as tuples in a new list. If one list is shorter than the other, the last element of the shorter list should be repeated as often as necessary. If one or both lists are empty, the empty list should be returned.</p>
<p>Please consider the following examples:</p>
<pre><code>merge([0, 1, 2], [5, 6, 7]) # should return [(0, 5), (1, 6), (2, 7)]
merge([2, 1, 0], [5, 6]) # should return [(2, 5), (1, 6), (0, 6)]
merge([], [2, 3]) # should return []
</code></pre>
<p>You can assume that the parameters are always valid lists and you do not need to provide any kind of input validation.</p>
<p>My attempt:</p>
<pre><code>def merge(a, b):
if len(a) == 0 or len(b) == 0:
mergelist = []
elif len(a) > len(b):
for i in range(0, len(b)):
mergelist = [a[i], b[i]]
for i in range(len(b), len(a)):
mergelist = [a[i], b[len(b)]]
elif len(b) > len(a):
for i in range(0, len(a)):
mergelist = [a[i], b[i]]
for i in range(len(a), len(b)):
mergelist = [a[len(a)], b[i]]
return mergelist
print(merge([0, 1, 2], [5, 6]))
</code></pre>
<p>Can someone tell me why my code is wrong? My IDE says</p>
<blockquote>
<p>the list index is out of range</p>
</blockquote>
<p>but i checked it over and over, it isn't,,,i think.</p>
<p>EDIT: I didn't think so many people would help me and give me their version of the code. They are extremely helpful. Thank you all so much!!!</p>

74,161,888 | <p>I have been learning and working with typescript. I am just curious to find out the correct signatures of express middlewares.
I have been defining middlewares as:</p>
<pre class="lang-js prettyprint-override"><code>const middleware = async(req: Request, res: Response, next: NextFunction) => {
// Middleware code here
if(ok)
next()
// Or I do
return next()

<p>Is this the correct way? What is considered the best practice?
Also what is supposed to be the return type of middlewares?</p>

74,161,897 | <p>I have a gradle Copy task that copies assets from the project directory into the build directory:</p>
<pre><code>tasks.register("copyAssets", Copy) {
def fromDir = "${project.projectDir.toString()}/../assets"
def toDir = "${project.buildDir.toString()}/assets"
println "Copying assets"
println " from $fromDir"
println " into $toDir"
from fromDir
into toDir
}
build.dependsOn copyAssets
run.dependsOn copyAssets
</code></pre>
<p>This works, but somehow it not only runs on <em>build</em> and <em>run</em>, but also on <em>clean</em>.</p>
<p>If I remove both lines with <code>dependsOn</code>, it doesn't run on <em>build</em>, <em>run</em>, or <em>clean</em>. But as soon as I put the line with <code>build.dependsOn</code> in, the task runs on <em>build</em>, <em>run</em>, and <em>clean</em>. If, on the other hand, I remove <code>build.dependsOn</code> and put in <code>run.dependsOn</code> instead, the outcome is the same: The task runs on <em>build</em>, <em>run</em>, and <em>clean</em>.</p>
<p>How does <code>dependsOn</code> work? How can I make it to run on <em>build</em> and <em>run</em>, but not on <em>clean</em>?</p>
<p>I use gradle wrapper, and it's a multi-module project, i.e.</p>
<pre><code>./gradlew main:clean
./gradlew main:build
./gradlew main:run
</code></pre>
<p>The task is in the <em>main</em> module only, not inside the top-level <code>build.gradle</code>.</p>

74,161,986 | <p>I am currently learning how to use the Bloc state management library in Flutter, and I have a scenario where I would like to listen to an action performed (e.g. clicking a button) and react to that action in a child widget down the widget tree using a Cubit. From the documentation, it seems like the only way to rebuild child widgets is by storing a state object and reacting to changes in the state. However in my case, I don't need to store any state, I just want to know if an action has been done and react every single time it has been invoked.</p>
<p>Given this example below, I want <code>WidgetB</code> to rebuild whenever the button in <code>WidgetA</code> has been pressed, but I can't figure out how to construct my Cubit to allow that without storing some kind of state object.</p>
<pre><code>import 'package:flutter/material.dart';
import 'package:flutter_bloc/flutter_bloc.dart';
// What should the code be here if I don't want to store any state?
class WidgetACubit extends Cubit<void> {
WidgetACubit({initialState}) : super(initialState);
void doSomething() => emit(null);
}
class App extends StatelessWidget {
App({super.key});
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: BlocProvider(
create: (_) => WidgetACubit(),
child: WidgetA(),
),
),
);
}
}
class WidgetA extends StatelessWidget {
WidgetA({super.key});
@override
Widget build(BuildContext context) {
return Column(
children: [

74,162,036 | <p>I am making an app that stores its settings in a .txt file. I am able to get the line count, but I don't know, how to store the text in one line in a variable. <br></p>
<p>For example:</p>
<pre><code>linecount = 0
datainfile = []
with open("txt.txt" , "r") as t:
linecount += 1
#Hoe to add lines to datainfile?
config1 = datainfile[0]
</code></pre>
