74,365,495 | <p>I am porting the Matlab code to Python. In Matlab, indices start at 1, but in python, they start at 0. Is there any way to set the first index as 1 through a command line flag?</p>
<p>It will be very useful for programming during index iteration.</p>

74,365,565 | <p>I'm opening a discord channel and busy looping reading messages from it with the below statement to get the elements:</p>
<pre><code>List<org.openqa.WebElement> ret = driver.findElement(By.tagName("main")) // driver = WebDriver
.findElements(By.tagName("li"))
.stream()
.filter(message -> message.getAttribute("id") != null
&& message.getAttribute("id").contains("chat-messages"))
.toList();
</code></pre>
<p>There are about 40 messages by default shown on the page, and it takes 5-6 seconds for every read. It is unacceptably long. I read that when there are no matches, findElements has an implicit wait time, but that is not the case here as there are elements returned in every read. Any idea what is causing this delay and how to improve it?</p>
<p>Update: From the first answer I received, I tried</p>
<pre><code>List<WebElement> ret = driver.findElements(By.xpath("//main//li[contains(@id,'chat-messages')]"));
</code></pre>
<p>At first it appeared like it was fast but soon I realized it must have been some temporary thing. It is taking just as long as before.</p>
<p>Update: Shamefully upon some debugging I found out that the driver.findElements is not the one taking several seconds, it only takes under 20 millis, but I have some code reading attributes from the remote web element of all of the returned elements, which is what is causing the delay. I have restructured the code now that it only has the read the attributes of the last message returned from findElements, and maintain its timestamp for identifying new messages next time.</p>

74,365,569 | <p>I have a dataset that looks like this in R:</p>
<pre><code>name = c("john", "john", "john", "alex", "alex", "peter", "peter", "peter", "peter")
year = c(2010, 2011, 2015, 2014, 2016, 2010, 2011, 2012, 2013)
age = c(21, 21, 21, 55, 55, 61, 61, 61, 61)
problem_data = data.frame(name, year, age)
name year age
1 john 2010 21
2 john 2011 21
3 john 2015 21
4 alex 2014 55
5 alex 2016 55
6 peter 2010 61
7 peter 2011 61
8 peter 2012 61
9 peter 2013 61
</code></pre>
<p>In this dataset, the age of each person at the last recorded year has been erroneously inserted at each row. For example - in reality:</p>
<ul>
<li>Peter was 61 in 2013</li>
<li>Peter was 60 in 2012</li>
<li>Peter was 59 in 2011</li>
<li>Peter was 58 in 2010</li>
</ul>
<p>Sometimes years are missing - as a result:</p>
<ul>
<li>Alex was 55 in 2016</li>
<li>Alex was 53 in 2014</li>
</ul>
<p>I am trying to research a way in R that can handle such a task. I have been trying to combine "cumulative group differences" and "max row conditions" - but I am not sure how these concepts can be combined together to achieve this:</p>
<pre><code># https://stackoverflow.com/questions/39237345/subtract-value-in-previous-row-for-each-section-of-a-data-frame-that-corresponds
library(dplyr)
new_data = problem_data %>%
group_by(name) %>%
mutate(real_age= age - lag(age, default = age[1]))
</code></pre>
<p>Bur this approach has made everyone's age as 0!</p>
<pre><code># A tibble: 9 x 4
# Groups: name [3]
name year age real_age
<chr> <dbl> <dbl> <dbl>
1 john 2010 21 0
2 john 2011 21 0
3 john 2015 21 0
4 alex 2014 55 0
5 alex 2016 55 0
6 peter 2010 61 0
7 peter 2011 61 0
8 peter 2012 61 0
9 peter 2013 61 0
</code></pre>
<p>Can someone please show me how to fix this problem?</p>
<p>Thank you!</p>

74,365,599 | <p>I have a pandas dataframe, df defined as follows:</p>
<pre><code>df = pd.DataFrame({'Year':[1,2,3,...],'A':[2000,4000,6000,...],'B':[200,400,600,...]})
</code></pre>
<p>where 'Year' goes from 1-40 but it can be any integer n.
I want to calculate a new column as follows</p>
<pre><code>df['C'] = 0.06*(df.A + df.B]
</code></pre>
<p>However I wish to calculate column C only for years</p>
<pre><code>years = [3,5,7,10]
</code></pre>
<p>i.e. I only want to perform the calculation when</p>
<pre><code>Year in [3,5,7,10,13,15,17,20,...]
</code></pre>
<p>for the first 50 years (assuming the dataframe has that many rows; in my case, the last year is 40)</p>

74,365,629 | <p>I have this perl command:</p>
<pre class="lang-bash prettyprint-override"><code># Result: o
#
echo foo | perl -pe 's/f(o)o/$1/'
</code></pre>
<p>I'd like the replacement expression to be passed via env variable:</p>
<pre class="lang-bash prettyprint-override"><code>echo foo | REPLACE='$1' perl -pe 's/f(o)o/$ENV{REPLACE}/'
</code></pre>
<p>however, in this case, Perl does not interpret the matching variable <code>$1</code>; instead, it just replaces it with the env variable value, so that the result is <code>$1</code>.</p>
<p>I know I can work this around via Bash string interpolation:</p>
<pre class="lang-bash prettyprint-override"><code>REPLACE='$1'
echo foo | perl -pe 's/f(o)o/'"$REPLACE"'/'
</code></pre>
<p>however, this is hackish (and limited).</p>
<p>Is the a more idiomatic Perl way to accomplish this task?</p>

74,365,638 | <p>I have informations about companies presented in a table. One of the field of this table is the mean value of each note the company received ('note_moyenne' in models.FicheIdentification).
By clicking on a button, people are able to submit a new note for the company ('note' in models.EvaluationGenerale). I want the mean value of the notes to update in the database each time someone submit a new note.</p>
<p>Here is my models.py :</p>
<pre><code>class FicheIdentification(models.Model):
entreprise=models.ForeignKey(Entreprise, on_delete=models.CASCADE)
note_moyenne=models.IntegerField()
def __str__(self):
return self.entreprise.nom_entreprise
class EvaluationGenerale(models.Model):
entreprise=models.ForeignKey(Entreprise, on_delete=models.CASCADE)
note=models.IntegerField()
commentaires=models.CharField(max_length=1000)
date_evaluation=models.DateField(auto_now_add=True)
def __str__(self):
return self.commentaires
</code></pre>
<p>views.py :</p>
<pre><code>class CreerEvaluationGenerale(CreateView):
form_class = FormulaireEvaluationGenerale
model = EvaluationGenerale
def form_valid(self, form):
form.instance.entreprise=Entreprise.objects.filter(siret=self.kwargs['siret']).first()
return super(CreerEvaluationGenerale, self).form_valid(form)
def get_success_url(self):
return reverse('details-evaluations')
</code></pre>
<p>Currently I just display the mean value in my table using this</p>
<pre><code>def render_evaluation(self, record):
return (EvaluationGenerale.objects.filter(entreprise=record.entreprise.siret).aggregate(Avg('note'))['note__avg'])
</code></pre>
<p>but I really don't like this solution as I want the value to be stored in the database, in FicheIdentification.note_moyenne.</p>
<p>I thought about creating a UpdateView class but couldn't manage to link it with my CreateView.</p>
<p>Any help or documentation would be really appreciated, I'm a bit lost right know...</p>

74,365,641 | <p>I have a button and a region.
When the button is pressed, I want it to show the region if the region is hidden, and hide the region if the region is shown. I'm trying to do this with a JavaScript condition. Here are the button and the region in the rendering pane:</p>
<p><a href="https://i.stack.imgur.com/Ft38k.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ft38k.png" alt="Rendering pane" /></a></p>
<p>Under the button there's a Dynamic Action that's triggered when the button is pressed. If the result is True then it should show the region and if the result is false then it should hide the region.</p>
<p>So all that is left is to add a JavaScript Expression under Client-side Condition to this Dynamic Action, something like</p>
<pre><code>if (*region is visible*)
return false;//hide the region
else
return true;//show the region
</code></pre>
<p>Problem is I don't know what the code is to find if a region is visible. I assigned a Static ID to the region called <code>TestRegionID</code>, and I guess it is referenced in JavaScript like this: <code>$(TestRegionID)</code></p>
<p>So how do I write this JavaScript expression?</p>
<p><strong>Update:</strong> Answer is just put <code>($(TestRegionID).is(":visible"))</code> in the JavaScript expression box and flip the Hide and Show action positions (True -> Hide, False -> Show)</p>

Button("Deselect") {
self.selection = nil

74,365,708 | <p>I currently am writing a Powershell script that remotely removes users from a local admin group on a list of servers. The CSV headers are Computer and Name. For each entry of user (name), matches the server (computer).</p>
<p>Ex.</p>
<pre class="lang-none prettyprint-override"><code>Computer,Name
Server1,User1
Server1,User2
Server2,User1
</code></pre>
<p>Script:</p>
<pre><code>$List = Import-CSV C:\temp\LocalAdmin.CSV
$user = $List.Name
$objGroup = $List.Computer
write-host "Removing user" $user "from server" $objGroup "local admin group:" -ForegroundColor Green
Invoke-Command -ComputerName $objGroup -ScriptBlock {Remove-LocalGroupMember -Group "Administrators" -Member $using:user }
write-host "Completed."
</code></pre>
<p>When the script runs, it runs through perfectly fine the first time through, but then it runs through the script line by line for how many ever lines there are causing it to attempt to remove the users multiple times. Can someone help me fix this logic? It is almost like the CSV is being read as an array vs a list. I appreciate the help!</p>

<p>A class is made with a function that calls the temperature of Rome, from an API. This info is then stored in a text file "romeweather.text". I need to store 200 lines of the data from that file into a list. The list part isnt working for me because the data is in the form of floats ex.15.67 on each line. I keep running into this error:</p>
<pre><code>Traceback (most recent call last):
File "main.py", line 111, in <module>
rome.append(float(line()))
TypeError: 'str' object is not callable
</code></pre>
<p>Please let me know how I can make it work.</p>

74,365,737 | <p>Prior to <strong>Isolated</strong> Azure Functions, one could create an <strong>Output binding queue</strong> like so:
<code>[Queue(...)] CloudQueue outputQueue</code></p>
<p>Then, we could add a new message with the ability to add a Visibility Delay like so:</p>
<pre><code>var cloudQueueMessage = new CloudQueueMessage("some message");
var timespan = new TimeSpan(0, 10, 0);
outputQueue.AddMessage(cloudQueueMessage, initialVisibilityDelay: timespan);
</code></pre>
<p>Now that we've migrated these Azure Function to the <strong>Isolated</strong> mode, how does one add a Visibility Delay to the message?</p>
<p>Here's an example from Microsoft's website
<a href="https://i.stack.imgur.com/9P0mJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9P0mJ.png" alt="enter image description here" /></a></p>

74,365,745 | <p>In <code>Android Studio</code> (version: Android Studio Dolphin 2021.3.1 Patch 1) before downloading virtual image with Android 12 (API 33, <code>Tiramisu</code>) I had to agree to the license agreement that start with the following worrying me statement:</p>
<blockquote>
<p>To get started with the Android SDK Preview, you must agree to the
following terms and conditions. As described below, please note that
this is a preview version of the Android SDK, subject to change, that
you use at your own risk. <strong>The Android SDK Preview is not a stable</strong>
<strong>release, and may contain errors and defects that can result in serious</strong>
<strong>damage to your computer systems, devices and data</strong>.</p>
</blockquote>
<p>The same for 32 API (Android 11). For Android 7 there was no such warning.
Is it safe now to install and use this emulators? What damage can happen to computer? How to prevent it? Does someone already install and use them?</p>
<p>In the <a href="https://www.reddit.com/r/PCSX2/comments/g7s71f/can_running_the_emulator_damage_your_laptop/" rel="nofollow noreferrer">similar question</a> I found the following recommendations about potential overheating PC:</p>
<blockquote>
<p>It could potentially damage your laptop if it overheats. But that is
why the fan is running. It is trying to cool down. If it gets too hot
your computer will start throttling programs, apps and processes to
try and cool down. And if it gets too hot it should shut itself down
to prevent damage. Make sure to keep and vents and fans clear, clean
and free for airflow.</p>
</blockquote>
<p>This is the only main problem with this emulators?</p>

74,365,747 | <p>i have been working on the leetcode problems these days but i always get stuck with the problems where the solutions have the .next syntax. normally i used to run the solutions in my VScode console to see what it happens. but my Vscode console doesn't recognize the .next syntax so...</p>
<p>can someone explain me by this " 83. Remove Duplicates from Sorted List " solution ?
<a href="https://leetcode.com/problems/remove-duplicates-from-sorted-list/description/" rel="nofollow noreferrer">https://leetcode.com/problems/remove-duplicates-from-sorted-list/description/</a></p>

while(current) {

current.next = current.next.next;
} else {
current = current.next;
}
}
return head;
};
deleteDuplicates([1,1,2,3,3])

74,365,763 | <p>I'm working on a Django middleware to store all requests/responses in my main database (Postgres / SQLite).
But it's not hard to guess that the overhead will be crazy, so I'm thinking to use Redis to queue the requests for an amount of time and then send them slowly to my database.
e.g. receiving 100 requests, storing them in database, waiting to receive another 100 requests and doing the same, or something like this.</p>
<p>The model is like this:</p>
<pre class="lang-py prettyprint-override"><code>url
method
status
user
remote_ip
referer
user_agent
user_ip
metadata # any important piece of data related to request/response e.g. errors or ...
created_at
updated_at
</code></pre>
<p>My questions are "is it a good approach? and how we can implement it? do you have any example that does such a thing?"
And the other question is that "is there any better solution"?</p>

<p>I would like to create three different tables according to the levels of <strong>participant</strong> variable. More or less the final result should be like the following one:</p>
<p><a href="https://i.stack.imgur.com/hoxnk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hoxnk.png" alt="enter image description here" /></a></p>
<p>I have started scripting the following code (since I am looking for to do this via a dplyr, apply family, loops or map function)</p>
<pre><code> list %>% as_data_frame() %>%
select(blockLabel, trial_resp.corr, participant, Freq, freq) %>%
map(~ flextable(.x))
</code></pre>
<p>But unfortunately, I get the following error code:</p>
<pre><code>Error in flextable(.x) : is.data.frame(data) is not TRUE
</code></pre>
<p>I am not an expert in this method thus if you would have something to suggest about fixing the problem and sharing knowledge to achieve the final result, please just let me know (in passing I specify that Correctness corresponds to 1 and Incorrcetness to 0 of trial_resp.corr variable)</p>
<p>Thanks</p>

74,365,918 | <p>I am trying to solve this question for 2 days but unable to solve it, gets really frustrated.
I hope anyone can help me to get rid out of this problem.</p>
<p>Write a program for given an integer list where each number represents the number of hops you can make in hopscotch game, determine whether you can reach to the last index starting at index 0.</p>
<p>For example, [2, 0, 1, 0] returns True while [1, 1, 0, 1] returns False.</p>
<p>Input Format</p>
<p>single line space separated integers</p>
<p>Constraints</p>
<p>len(list) > 0</p>
<p>Output Format</p>
<p>Boolean True or False</p>
<p>Sample Input 0</p>
<pre><code>2 3 1 1 4
</code></pre>
<p>Sample Output 0</p>
<pre><code>True
</code></pre>
<p>Explanation 0</p>
<p>Input: nums = [2,3,1,1,4]
Output: True
Explanation: Jump 1 step from index 0 to 1, then 3 steps to the last index.
Sample Input 1</p>
<pre><code>3 2 1 0 4
</code></pre>
<p>Sample Output 1</p>
<pre><code>False
</code></pre>
<p>Explanation 1</p>
<p>Input: nums = [3,2,1,0,4]
Output: False
Explanation: You will always arrive at index 3 no matter what. Its maximum jump length is 0, which makes it impossible to reach the last index.</p>

74,365,933 | <p>The .NET v7 framework introduced the concept of Route Groups to group mapped endpoints together based on a common prefix in the path:</p>
<pre class="lang-cs prettyprint-override"><code>app.MapGroup("/public/todos").MapTodosApi();
</code></pre>
<p>Now, in order to return an absolute path for the <code>Created</code> response (i.e. to a <code>POST</code> request), I need that route path prefix inside the service. This usecase is even discussed <a href="https://devblogs.microsoft.com/dotnet/asp-net-core-updates-in-dotnet-7-preview-4/#route-groups" rel="nofollow noreferrer">in the official documentation</a>:</p>
<blockquote>
<p>Instead of using relative addresses for the Location header in the 201 Created result, it’s also possible to use GroupRouteBuilder.GroupPrefix to construct a root-relative address</p>
</blockquote>
<p>However, the <code>GroupRouteBuilder</code> class does not exist. There is only a <a href="https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.routing.routegroupbuilder?view=aspnetcore-7.0" rel="nofollow noreferrer"><code>RouteGroupBuilder</code></a>, but an instance of it has no member <code>GroupPrefix</code>. Any suggestions how to actually get the prefix?</p>

74,365,997 | <p>I'm Getting some arrays from some wordpress custom fields:</p>
<pre><code>$content = array(get_post_meta($postId, 'content'));
$media = array(get_post_meta($postId, 'media'));
$yt = array(get_post_meta($postId, 'youtube'));
</code></pre>
<p>I then need to have it printing in sequence, like:</p>
<blockquote>
<p>media</p>
<p>content</p>
<p>LInk</p>
<p>Embed</p>
</blockquote>
<p>And repeat the sequence for each value</p>
<pre><code>media
content
LInk
Embed
</code></pre>
<p>For the sequence I'd use this:</p>
<pre><code>echo '<ul>';
for ($i = 0; $i < count($all_array['media']); $i++) {
for ($j = 0; $j < count($all_array['content']); $j++) {
for ($k = 0; $k < count($all_array['youtube']); $k++) {
echo '<li>media->' . $all_array['media'][$i] . '</li>';
echo '<li>content->' . $all_array['content'][$j] . '</li>';
echo '<li>link->' . $all_array['link'][$k] . '</li>';
}
}
}
echo '</ul>';
</code></pre>
<p>But I'm doing something wrong with the merging of the 3 fields as if I do a <code>var_dump</code> before to run the <code>for</code> bit, like</p>
<pre><code>echo '<pre>' . var_export($all_array, true) . '</pre>';
</code></pre>
<p>Then this is what I get and I cannot iterate as I wish:</p>
<pre><code>array (
0 =>
array (
0 =>
array (
0 => '
brother
',
1 => '
Lorem
',
2 => '
End it
',
),
1 =>
array (
0 => '337',
1 => '339',
),
2 =>
array (
0 => 'https://www.youtube.com/watch?v=94q6fzbJUfg',
),
),
)
</code></pre>
<p>Literally the layout in html that I'm looking for is:</p>
<ol>
<li>image</li>
<li>content</li>
<li>link</li>
<li>image</li>
<li>content</li>
<li>link
...</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>This how I am merging the arrays:</p>
<pre><code>foreach ( $content as $idx => $val ) {
$all_array[] = [ $val, $media[$idx], $yt[$idx] ];
}
</code></pre>
<p>This is the associative array how it looks like:</p>
<p>Content:</p>
<pre><code> array (
0 =>
array (
0 => '
brother
',
1 => '
Lorem
',
2 => '
End it
',
),
)
</code></pre>
<p>Media</p>
<pre><code> array (
0 =>
array (
0 => '337',
1 => '339',
),
)
</code></pre>
<p>Youtube</p>
<pre><code> array (
0 =>
array (
0 => 'https://www.youtube.com/watch?v=94q6fzbJUfg',
),
)
</code></pre>

74,366,003 | <p>Component:</p>
<pre><code>const MyComponent = props => {
const {price} = props;
const result1 = useResult(price);
return (
<div>...</div>
)
}
</code></pre>
<p>Custom Hook:</p>
<pre><code>export const useResult = (price) => {
const [result, setResult] = useState([]);
useEffect(() => {
const data = [{price: price}]
setResult(data);
}, [price]);
return result;
};
</code></pre>
<p>Jest test:</p>
<pre><code> it('should ...', async () => {
render(
<MyComponent price={300}/>)
)
await waitFor(() => {
expect(...).toBeInTheDocument();
});
});
</code></pre>
<p>What it does happen with the above code is that <code>MyComponent</code>, <strong>when running the test</strong>, renders only once instead of two (when the application runs). After the initial render where <code>result1</code> is an empty array, <code>useEffect</code> of <code>useResult</code> is running and since there is a state change due to <code>setResult(data)</code>, I should expect <code>MyComponent</code> to be re-rendered. However, that's not the case and <code>result1</code> still equals to <code>[]</code> whereas it should equal to <code>[{price:300}]</code>.</p>
<p>Hence, <em>it seems custom hooks under testing behave differently than the real app</em>. I thought it would be okay to test them indirectly through the component that calls them.</p>
<p><em><strong>Any explanation/thoughts for the above</strong></em>?</p>
<p><em><strong>UPDATE</strong></em></p>
<p><em>The issue that invoked the above erroneous behaviour was <strong>state mutation</strong>!! It worked with the app but not with the test! My mistake was to attempt to use <code>push</code> in order to add an element to an array that was a state variable...</em></p>

74,366,132 | <p>I need a type/interface to define a property that can be object or an array.
The problem with typescript <code>|</code> operator is that if I use it I will have to explicitly check each time if the variable is array or not but I always know if its an object or an array. So instead I ended up using <code>as SomeType</code> or <code>as SomeType[]</code>. What I want is to not have to do it.</p>
<p>So current idea is to create a mixture of object and array, so that instead of array checks or "as" assertions I will have to add <code>?.</code> everywhere.</p>
<p>My current solution is</p>
<pre><code>interface _Array<T> extends Array<T | undefined> {}
type ArrayORObject<T> = Partial<T> & Partial<_Array<T>>;
</code></pre>
<p>Which almost works but the only issue is that now I'm getting "Index signature for type 'number' is missing in type SomeObject", seems that it requires objects to have Array index signature ([index: number]), but I can't figure out if its possible to have optional index signature.</p>
<p>Edit: Thanks for suggesting "satisfies" but bumping TS to beta version not really an option rn. adding call to makeOrder() isn't much better then creating some function that will check if array.</p>

74,366,179 | <p>I'm developing a custom shell. In this assignment, I need to implement uniq-like command.

<p>I have no problem with the algorithm. I wrote a function which can do take exactly same operation with desired one. However, the problem is that, what are these types of outputs and inputs? I mean when I command <em>cat input.txt</em>, are these lines just one string or are they given in array? As I said, algorithm is ok but I do not know how to apply that correct algorithm in the shell? Any help or idea is appreciated.</p>

74,366,194 | <p>I'm using react and context: When I fetch items and there is no data, I send null. null becomes undefined (within res.send). In my reducer, I use spread operator when new items are being added. That results in an err as I'm trying to spread undefined (when there is no items yet and later added its first undefined).</p>
<p>What is good practice and what should I do in this case to change undefined into an empty array or so? Thank you</p>
<pre class="lang-js prettyprint-override"><code>const initialState = {
isFetchingItems: null,
items: [],
fetchErrorMessage: null
}
const reducer = (state, action) => {
switch (action.type) {
case 'FETCH_ITEMS':
return {
...state,
isFetching: true
}
case 'FETCH_ITEMS_SUCCESS':
return {
...state,
items: action.payload.messages,
isFetching: false
}
case 'FETCH_ITEMS_ERROR':
return {
...state,
fetchErrorMessage: action.payload,
isFetching: false
}
case 'ADD_ITEMS_SUCCESS':
return {
...state,
items: [action.payload, ...state.items] // here the err comes from as its like [action.payload, ...undefined]
}
default:
return state;
}
};
</code></pre>
<p>My action:</p>
<pre class="lang-js prettyprint-override"><code>const fetchItems = async() => {
dispatch({ type: 'FETCH_ITEMS' })
try {
let items = await API.fetchItems();
dispatch({ type: 'FETCH_Items_SUCCESS', payload: items })
} catch (error) {
dispatch({ type: 'FETCH_ITEMS_ERROR', payload: error.message })
}
};
const fetchItems = async() => {
// ...
dispatch({ type: 'ADD_ITEMS_SUCCESS', payload: items })
// ...

74,366,207 | <p>Objective: From a time-series df, make a plot of each occurrence of a particular state (or factor level) with x timepoints before, and y timepoints after, the onset (i.e. first row) of that state. The graph should be centered on zero (on the x-axis), such that the x timepoints before the event are negative values, and the y timepoints after the event are positive values. This is the same principal as a peristimulus time histogram.</p>
<p>The data: I have time-series data where different states can occur for variable amounts of time. First I use run length encoding (rle) to determine the start and stop of each run of each state (not shown). Second, I use a function, <a href="https://stackoverflow.com/questions/13155609/returning-above-and-below-rows-of-specific-rows-in-r-dataframe/13155669#13155669">similar to the one described here</a>, to return, say one row above and two rows below the onset of a particular state (state "A" in the example below). Here’s what that data looks like.</p>
<pre><code>df <- data.frame(
state = c("A","A","A","A","A","B","A","A","X","Y","Z","A","A","A","B","A","A"),

rleGroup = c("1","1","1","1","1","2","3","3","4","5","6","7","7","7","8","9","9"),

<p>The problem: I want to plot each extracted run of state A (i.e., one timepoint before and two timepoints after A.start). One thought is to make a unique identifier for each run grouping of state "A" (Question 1), and then make a time sequence counter that reflects the desired rows before and after the onset of state A (Question 2).</p>
<p>QUESTION NUMBER 1.
Create a unique identifier for each "plotGroup", defined as each run of state A (i.e., a row before A.start and two rows after A.start)
I tried this, but it's not quite working</p>
<p>extracted %>%
mutate(plotGroup = cumsum(lag(state) == "A" & state != "A"))</p>
<p>it should look like this</p>
<pre><code>extracted$plotGroup <- c("0","0","0","1","1","1","1","2","2","2","2","3","3","3")
stateStart state start rleGroup data plotGroup
1 A.start A start 1 0.85118187 0
2 A.NA A NA 1 0.23502147 0
3 A.NA A NA 1 0.97435662 0
6 B.NA B NA 2 0.80561653 1
7 A.start A start 3 0.27228361 1
8 A.NA A NA 3 0.07008506 1
9 X.NA X NA 4 0.44101076 1
11 Z.NA Z NA 6 0.65693316 2
12 A.start A start 7 0.45831802 2
13 A.NA A NA 7 0.83629347 2
14 A.NA A NA 7 0.62107270 2
15 B.NA B NA 8 0.53294588 3
16 A.start A start 9 0.08533221 3
17 A.NA A NA 9 0.28805362 3
</code></pre>
<p>QUESTION NUMBER 2. Create a "counter," centered on zero, of one row above and two rows after the A.start
This I have no idea how to do! But presumably can make use of "span" in the function
This is my desired output</p>
<pre><code>extracted$span <- c("0","1","2","-1","0","1","2","-1","0","1","2","-1","0","1")
stateStart state start rleGroup data plotGroup span
1 A.start A start 1 0.85118187 0 0
2 A.NA A NA 1 0.23502147 0 1
3 A.NA A NA 1 0.97435662 0 2
6 B.NA B NA 2 0.80561653 1 -1
7 A.start A start 3 0.27228361 1 0
8 A.NA A NA 3 0.07008506 1 1
9 X.NA X NA 4 0.44101076 1 2
11 Z.NA Z NA 6 0.65693316 2 -1
12 A.start A start 7 0.45831802 2 0
13 A.NA A NA 7 0.83629347 2 1
14 A.NA A NA 7 0.62107270 2 2
15 B.NA B NA 8 0.53294588 3 -1
16 A.start A start 9 0.08533221 3 0
17 A.NA A NA 9 0.28805362 3 1
</code></pre>
<p>Ultimate objective: plot data by span for each individual plotgroup</p>
<pre><code>ggplot(data=extracted, aes(x=span, y = data, group = plotGroup)) + geom_line()
</code></pre>

74,366,230 | <p>I often get a list of names I need to update in a table from an Excel list, and I end up creating a SSIS program to reads the file into a staging table and doing it that way. But is there I way I could just copy and past the names into a table from Management Studio directly? Something like this:</p>
<pre><code>create table #temp (personID int, userName varchar(15))
Insert
Into #temp (userName)
values (
'kmcenti1',
'ladams5',
'madams3',
'haguir1',
)
</code></pre>
<p>Obviously this doesn't work but I've tried different variations and nothing seems to work.</p>

74,366,239 | <p>If you're using JS, the documentation works well. But in case of angular I would prefer to handle observables instead of promises. The problem is that this kind of promise has a handler. I tried many approaches listed below but nothing seems to work.</p>
<pre><code>from(listen("click", v => v))
</code></pre>
<pre><code>let x = async() => listen("click", v => v)
</code></pre>
<p>Does anyone know how to convert this kind of event to an <code>Observable</code>?</p>
<p>The response is always this:</p>
<pre><code>function () {
var self = this,
args = arguments;
return new Promise(function (resolve, reject) {
var gen = fn.apply(self, args);
function _next(value) {
asyncGeneratorStep(gen, resolve, reject, _next, _throw, "next", value);
}
function _throw(err) {
asyncGeneratorStep(gen, resolve, reject, _next, _throw, "throw", err);
}
_next(undefined);
});
}

74,366,264 | <p>I'm creating a Vue3 web app and I was wondering what is the best way to pass data from parent to nested components (more specific, from parent to child of children).</p>
<p>Let's say I have this schema:</p>
<pre><code> Card
|
|
CardHeader CardBody
|
|
BodyHeader BodyParams BodyResponse
</code></pre>
<p>And I want to know the best way to pass data from Card to BodyHeader, BodyParams and BodyResponse</p>
<p>On <code>Card Component</code> I will be fetching some data from an API. Lets say that i fetch a json like this:</p>
<pre><code>{
header: {
title: 'hello header'
},
body: {
headers: ['authorization', 'anotherheader']
params: ['currency', 'hair'],
response: ['200', '401']
}
}
</code></pre>
<p>I know I just could do this:</p>
<p><code><Card/></code> :</p>
<pre><code><template>
<CardHeader :header="hedaer"></CardHeader>
<CardBody :body="body"></CardBody>
</template>
</code></pre>
<p>Then, in <code><CardBody/></code> :</p>
<pre><code><template>
<CardBodyHeader :headers="body.headers"></CardBodyHeader>
<CardBodyParams :params="body.params"></CardBodyParams>
<CardBodyResponse :responses="body.responses"></CardBodyResponse>
</template>
<script>
import CardBodyHeader from "./CardBodyHeader.vue";
import CardBodyParams from "./CardBodyParams.vue";
import CardBodyResponse from "./CardBodyResponse.vue";
export default {
components: { CardBodyHeader, CardBodyParams, CardBodyResponse },
props: {
body: {type: Object}
}
};
</script>
</code></pre>
<p>But I don't know if that would be the optimal solution.</p>

74,366,280 | <p>Here is a Rest Api method that sets the user rating. The database table contains the composite primary key: <code>user_id</code> + <code>rate_id</code>.</p>
<p>When user tries to set the same rating the framework throws an exception. I catch it and return response.</p>
<p>How to handle such these cases and make the method idempotent?</p>

74,366,357 | <p>I just updated my Visual Studio instance from 17.3.6 to 17.4.0. Then I tried a clean build of my solution. Suddenly one of my projects gives me linker errors</p>
<pre><code>8>pch.obj : error LNK2001: unresolved external symbol __imp___tls_index_?init@?1??lazy_init_num_threads@internal@at@@YAXXZ@4_NA

<p>This completely confuses me. When I turn on verbose linking I see it finding all sorts of similar symbols in MSVCRTD.lib. For example.</p>
<pre><code>2> Found _tls_index
2> Found __dyn_tls_init

<p>Anyone else encountering this?</p>

74,366,373 | <p>I've ready many stackoverflow answer, watched youtube videos and read many articles, and I still can't completely understand why we need two tokens. Here are my assumptions, please tell me where I am going wrong:</p>
<p>Access Token:</p>
<ol>
<li><p>Result of some oauth flow, where an application requests for access to a resource on my behalf.</p>
</li>
<li><p>Contains information about what access has been granted</p>
</li>
<li><p>Can be any string format (Not necessarily a JWT), it's only important that the intended recipient can understand it.</p>
</li>
<li><p>Could potentially contain information about the ID of the person who granted the access (Me!)</p>
</li>
<li><p>Must be kept secret!</p>
</li>
</ol>
<p>ID Token:</p>
<ol>
<li><p>Result of oidc flow(extension on top of oauth flow)</p>
</li>
<li><p>Contains information about the user (Me!) who authenticated, for example their username.</p>
</li>
<li><p>Is intended as nothing more than a standardized way to distribute information about the user. No actions are actually performed using the Id Token</p>
</li>
<li><p>Can be leaked without danger.</p>
</li>
</ol>
<p>Access token "flow":</p>
<p>User X wants Service A to access Service B on its behalf</p>
<p>User X is directed to Service B and authenticates</p>
<p>Service B sends an access token to Service A</p>
<p>Service A can now access Service B on behalf of User X according to the access rights contained within the token.</p>
<p>Id token "flow":</p>
<p>User X signs up for Service A using Login to Service B.</p>
<p>User X is directed to Service B and authenticates.</p>
<p>Service B sends Id token to Service A.</p>
<p>Service A can now display a personalized welcome message, "Hello User X"</p>
<p>Is any of this wrong or am I missing something?</p>
<p>Am I wrong in thinking that potentially User X could Authenticate against Service B, and grant access rights (access token) to some UserInformationAPI of Service B to Service A, which could then use that token to query Service B to read user information, and that this is in essence the same result as simply passing a standardized Id token to Service A directly?</p>

74,366,421 | <p>Working with a Java client/server application and no access to source code.</p>

Most of the time it works but sporadically it fails with the following error.</p>

</code></pre>
<p>When it fails it will do so for a number of attempts and then all of a sudden work fine again.</p>
<p>In an attempt to capture the URL calls, the application was started via the command line and referenced the logging.properties file with the following entry.</p>
<pre><code> sun.net.www.protocol.http.HttpURLConnection.level = ALL

<p>This generated some good information but there was no reference as to the port it was attempting to open on the client side.</p>

What entry needs to be added to the logging.properties file to capture the port the client is attempting to use?</li>

74,366,426 | <p>how can I exclude numbers from a range without creating a giant list?</p>
<p>How would I get all the numbers from 1, 100, for example, but exclude every nth number?</p>
<p>And what about with multiple n's? Exclude every 3rd and every 11th number, for example.</p>
<p>What's the best way to do this?</p>
<p>It's easy to do with if statements and appending to a list, but that becomes useless for any range of a large size, because I don't want a list with a million items.</p>
<p>basically I have a very large range of numbers and i want to exclude those which are divisible by 3.</p>
<p>using an if statement and checking %3 for every single number is also really inefficient</p>
<p>everything seems so simple in python that it seems I should be able to just skip every 3rd number, but much googling has left me without an answer.</p>
<p>is there no easy, efficient way to do this?</p>

74,366,436 | <p>I am training a multi-task transformer for a project and would like to switch my data structure over to TFRecords because my training is bottle-necked by on-the-fly data generation. I am currently structuring a single sample of data as a dictionary of tensors, like this:</p>
<p><code>{'continuous_input': tf.Tensor(), 'categorical_input': tf.Tensor(), 'continuous_output': tf.Tensor(), 'categorical_output': tf.Tensor()}</code></p>
<p>Within a sample, these 4 tensors have the same length, but between samples, these tensors vary in length. The two <code>continuous_</code> tensors are tf.float32, whereas the two <code>categorical_</code> tensors are tf.int32. More explicit details of these tensors are in the code below.</p>
<p>I think that I've successfully written my data to TFRecords in the correct format (byte-strings).</p>
<p><strong>Problem statement:</strong> I am unable to figure out how to read these TFRecords back into memory and parse the byte-strings into the dictionary of tensors structure above. I include a fully reproducible example of my issue below, which uses Numpy v1.23.4 and Tensorflow v2.10.0. It creates fake data with the aforementioned dictionary structure, saves TFRecords to your working directory, reloads these TFRecords and attempts to parse them with my function <code>parse_tfrecord_fn()</code>. I know that the issue lies in <code>parse_tfrecord_fn()</code> but I do not know the appropriate <code>tf.io</code> tool to resolve this.</p>
<p><strong>Reproducible example:</strong></p>
<pre><code>import os
import os.path as op
import numpy as np
import tensorflow as tf
# Helper functions for writing TFRecords
def _tensor_feature(value):
serialized_nonscalar = tf.io.serialize_tensor(value)
return tf.train.Feature(bytes_list=tf.train.BytesList(value=[serialized_nonscalar.numpy()]))
def create_example(sample):
feature = {
"continuous_input": _tensor_feature(sample['continuous_input']),
"categorical_input": _tensor_feature(sample['categorical_input']),
"continuous_output": _tensor_feature(sample['continuous_output']),
"categorical_output": _tensor_feature(sample['categorical_output']),
}
return tf.train.Example(features=tf.train.Features(feature=feature)).SerializeToString()
# Helper functions for reading/preparing TFRecord data
def parse_tfrecord_fn(example):
feature_description = {
"continuous_input": tf.io.VarLenFeature(tf.string),
"categorical_input": tf.io.VarLenFeature(tf.string),
"continuous_output": tf.io.VarLenFeature(tf.string),
"categorical_output": tf.io.VarLenFeature(tf.string)
}
example = tf.io.parse_single_example(example, feature_description)
# TODO: WHAT GOES HERE?
return example
def get_dataset(filenames, batch_size):
dataset = (
tf.data.TFRecordDataset(filenames, num_parallel_reads=tf.data.AUTOTUNE)
.map(parse_tfrecord_fn, num_parallel_calls=tf.data.AUTOTUNE)
.shuffle(batch_size * 10)
.batch(batch_size)
.prefetch(tf.data.AUTOTUNE)
)
return dataset
# Make fake data
num_samples_per_tfrecord = 100
num_train_samples = 1600
num_tfrecords = num_train_samples // num_samples_per_tfrecord
fake_sequence_lengths = np.random.randint(3, 35, num_train_samples)
fake_data = []
for i in range(num_train_samples):
seq_len = fake_sequence_lengths[i]
fake_data.append({'continuous_input': tf.random.uniform([seq_len], minval=0, maxval=1, dtype=tf.float32),
'categorical_input': tf.random.uniform([seq_len], minval=0, maxval=530, dtype=tf.int32),
'continuous_output': tf.fill(seq_len, -1.0),
'categorical_output': tf.fill(seq_len, -1)})
tfrecords_dir = './tfrecords'
if not op.exists(tfrecords_dir):
os.makedirs(tfrecords_dir) # create TFRecords output folder
# Write fake data to tfrecord files
for tfrec_num in range(num_tfrecords):
samples = fake_data[(tfrec_num * num_samples_per_tfrecord): ((tfrec_num + 1) * num_samples_per_tfrecord)]
with tf.io.TFRecordWriter(tfrecords_dir + "/file_%.2i.tfrec" % tfrec_num) as writer:
for sample in samples:
example = create_example(sample)
writer.write(example)
# (Try to) Load all the TFRecord data into a (parsed) tf dataset
train_filenames = tf.io.gfile.glob(f"{tfrecords_dir}/*.tfrec")
# Problem: the line below doesn't return the original tensors of fake_data, because my parse_tfrecord_fn is wrong
# Question: What must I add to parse_tfrecord_fn to give this the desired behavior?
dataset = get_dataset(train_filenames, batch_size=32)
# For ease of debugging parse_tfrecord_fn():
dataset = tf.data.TFRecordDataset(train_filenames, num_parallel_reads=tf.data.AUTOTUNE)
element = dataset.take(1).get_single_element()
parse_tfrecord_fn(element) # set your breakpoint here, then can step through parse_tfrecord_fn()
</code></pre>
<p>The function <code>parse_tfrecord_fn()</code> accepts a byte-string as input, which looks like this:</p>
<p>example = "b'\n\xb4\x03\nj\n\x10continuous_input\x12V\nT\nR\x08\x01\x12\x04\x12\x02\x08\x12"H..."</p>
<p>The command <code>example = tf.io.parse_single_example(example, feature_description)</code>, where the arguments are defined as in the my reproducible example, returns a dictionary of <code>SparseTensors</code> with the desired 4 keys ('continuous_input', 'categorical_input', etc.). However, the <em>values</em> of these SparseTensors are either absent or inaccessible to me, so I cannot extract them and parse them, such as with <code>tf.io.parse_tensor(example['continuous_input'].values.numpy().tolist()[0], out_type=tf.float32)</code>.</p>

I don't know if this is purposeful and I've searched our DNN modules code but haven't found an such reference.</p>
<p>The other devs can confirm they haven't added such code. I've searched the code folders for a file named events.js but haven't found one. I'm aware that DNN has large portions of it that are data driven but I don't know what tables to query to see if there's code that has that URL.</p>
<p>Is anyone aware if DNN or kendo controls has an references to tiktok?</p>

import styles from "./Button.module.scss";
type Variant = "default" | "primary" | "tertiary";
interface Props {
children: String;
variant: Variant;
}
export const Button: React.FC<Props> = ({ children, variant }) => {
return <button className={`${styles.button} ${variant}`}>{children}</button>;
};
</code></pre>
<p>and here is the <code>Button.module.scss</code> file:</p>
<pre class="lang-scss prettyprint-override"><code>.button {
border: none;
padding: 0.5rem 1.5rem;
border-radius: 0.25rem;
background-color: grey;
color: white;
&.default {
background-color: green;
}
&.primary {
background-color: red;
}
}
</code></pre>
<p>What I expect, is to have a green button if I use the component like <code><Button variant="default">I'm green</Button></code>, but instead I'm getting the grey button.</p>
<p>Here is a live example on <a href="https://codesandbox.io/s/clever-varahamihira-topfyf?file=/src/components/Button.tsx" rel="nofollow noreferrer">codesandbox</a></p>
<p>I'm stuck on this, could somebody help me to apply different styles based on prop values?</p>

74,366,559 | <p>This is just a conceptual question to test if I understand how X works.</p>
<p>Let's I have an X server running on machine A. If I make a new directory called <code>/tmp/.X11-unix</code> on on machine B, and use sshfs to mount <code>root@A:/tmp/.X11-unix</code> to <code>root@B:/tmp/.X11-unix</code>, would I be able to download statically compiled binaries on machine B that used X and see their display output on machine A?</p>
<p>When I tried this experiment, exporting the same <code>DISPLAY</code> variable on B as the one on A, I got the <code>display unavailable</code> error when trying out <a href="https://portacle.github.io/" rel="nofollow noreferrer">Portacle</a>. I know that Portacle can display its output when working on a very minimal machine because when I run it on a busybox container, I can see the emacs window, so what is failing here? Does the problem lie in writing to a remote file or is something else missing on machine B?</p>

74,366,585 | <p>I am working on a project that has a GUI and tanks that move. While tanks move fine, I am not able to figure out how to move/rotate them individually. I also need to clean my code as I feel I have a lot of extra stuff going on.</p>
<p>Here is some code, and here's what I tried.</p>
<p>I have four classes. <em>Missiles</em>, <em>Tanks</em>, and <em>Board</em>. I am calling keylisteners in the <em>Tank</em> class. Should I do that in the doDrawing method? The doDrawing method is in the <em>Board</em> class.</p>
<pre><code>private void doDrawing(Graphics g)
{
final double rads = Math.toRadians(120);
final double sin = Math.abs(Math.sin(rads));
final double cos = Math.abs(Math.cos(rads));
final int w = (int) Math.floor(tank1.getX() * cos + tank1.getX() * sin);
final int h = (int) Math.floor(tank1.getY() * cos + tank1.getY() * sin);
Graphics2D g2d = (Graphics2D) g;
g2d.translate(w, h);
g2d.rotate(rot, tank1.getX(), tank1.getY());
AffineTransform backup = g2d.getTransform();
AffineTransform trans = new AffineTransform();
g2d.setTransform(backup);
//g2d.drawImage(tank1.getImage(), tank1.getX(), tank1.getY(), this);
trans.setToIdentity();
trans.rotate(rot, h, w);
trans.translate(h, w);
trans.setTransform(backup);
g2d.drawImage(tank1.getImage(), tank1.getX(), tank1.getY(), this);
//g2d.drawImage(tank1.getImage(), tank1.getX(), tank1.getY(), this);
g2d.drawImage(tank2.getImage(), tank2.getX(), tank2.getY(), this);
List<Missile> missiles = tank1.getMissiles();
for (Missile missile : missiles)
{
//trans.rotate(Math.toRadians(rads), w/2, h/2);
g2d.drawImage(missile.getImage(), missile.getX(), missile.getY() - 7, this);
//g2d.rotate(rot, missile.getX(), missile.getY() - 7);
}
}

74,366,603 | <p>I have written a piece of code that I am using to research the behavior of different libraries and functions. And doing so, I stumbled upon some strange behavior with sscanf.</p>
<p>I have a piece of code that reads an input into a buffer, then tries to put that value into a numeric variable.</p>
<p>When I call sscanf from main using the input buffer, and the format specifier %x yields a garbage value if the input string is shorter than the buffer. Let's say I enter 0xff, I get an arbitrarily large random number every time. But when I pass that buffer to a function, all calls to scanf result in 255 (0xff) like I expect, regardless of type and format specifier mismatch.</p>
<p>My question is, why does this happen in the function main but not in the function test?</p>
<p>This is the code:</p>
<pre><code>#include <stdio.h>
int test(char *buf){
unsigned short num;
unsigned int num2;
unsigned long long num3;
sscanf(buf, "%x", &num);
sscanf(buf, "%x", &num2);
sscanf(buf, "%x", &num3);
printf("%x", num);
printf("%x", num2);
printf("%x", num3);
return 0;
}
void main(){
char buf[16];
unsigned long long num;
printf("%s","Please enter the magic number:");
fgets(buf, sizeof(buf),stdin);
sscanf(buf, "%x", &num);
printf("%x\n", num);
test(&buf);
}
</code></pre>
<p>I expect the behavior to be cohesive; all calls should fail, or all calls should succeed, but this is not the case.</p>
<p>I have tried to read the documentation and do experiments with different types, format specifiers, and so on. This behavior is present across all numeric types.</p>
<p>I have tried compiling on different platforms; gcc and Linux behave the same, as do Windows and msvc.</p>
<p>I also disassembled the binary to see if the call to sscanf differs between main() and test(), but that assembly is identical. It loads the pointer to the buffer into a register and pushes that register onto the stack, and calls sscanf.</p>
<p>Now just to be clear:
This happens consistently, and num in main is never equal to num, num2 or num3 in test, but num, num2 and num3 are always equal to each other.
I would expect this to cause undefined behavior and not be consistent.
Output when run - every time</p>
<pre><code>./main
Please enter the magic number: 0xff
0xaf23af23423 <--- different every time
0xff <--- never different
0xff <--- never different
0xff <--- never different
</code></pre>
<p>The current reasoning I have is in one instance sscanf is interpreting more bytes than in the other. It seems to keep evaluating the entire buffer, getting impacted by residual data in memory.</p>
<p>I know I can make it behave correctly by either filling the buffer, with that last byte being a new line or using the correct format specifier to match the pointer type. "%llx" for main in this case. So that is not what I am wondering; I have made that error on purpose.</p>
<p>I am wondering why using the wrong format specifier works in one case but not in the other consistently when the code runs.</p>

<p>I am working with mongoose and nodeJS. I am using the aggregate function with $group but I'm not getting the expected results and I would like to know what I'm doing wrong. My goal is to group all 'sucursales' without repeating any elements, each 'sucursal' should have an array of all the 'productos' that are in each 'sucursal' with the same name but without repeating any 'producto', instead of repeating the element, the function should add the value to the element with the same name (see the data example above).</p>
<p>The code that I'm using is this:</p>
<pre><code>const ordenesTotal = await OrdCompCli.aggregate([
{
$match: {fechaEntrega: new Date(fecha), estado: {$gt : 0, $lt : 5}}
},
{
$unwind: "$productos"
},
{
$group: {
_id: "$sucursal",
productos: {
$addToSet: {
producto: "$productos.producto",
totalKilos: {
$sum: "$productos.kilos"
}
}
}
}
},
{
$project: {
_id: 0,
sucursal: "$_id",
productos: 1
},
},
])
</code></pre>
<p>this code gave me this result:</p>
<pre><code>{
sucursal: 1
productos: [
{
producto: 1,
kilos: 50
},
{
producto: 2,
kilos: 40
},
{
producto: 1,
kilos: 50
},
]
},
{
sucursal: 2
productos: [
{
producto: 1,
kilos: 30
},
{
producto: 2,
kilos: 50
}
]
}
</code></pre>
<p>and this result is not what I'm expecting because the 'producto' with the same name are not being grouped.
Can someone tell me what I'm doing wrong?</p>

74,366,649 | <p>I've been using <code>graphql-codegen</code> for several month, it's a great tool.<br />
I've always used it with <code>@tanstack/react-query</code> <code>useQuery</code> & <code>useMutation</code> hooks.</p>
<p>Today, I would like to use it with <code>useQueries</code> (<a href="https://tanstack.com/query/v4/docs/guides/parallel-queries" rel="nofollow noreferrer">documentation</a>).<br />
To give you more inputs, I'm receiving a dynamic (then undeterministic) list of ids of same type, and I would like to populate them by querying my graphql api. Because of recursive issues, I can't do reconsiliation on server, so I have to do it on client. This is why I need to batch single queries. And this is why I wish I could use <code>useQueries</code>.</p>
<p>It looks like there's no interoperability with <code>graphql-codegen</code> & <code>useQueries</code>.<br />
Do you confirm ?<br />
If so, which pattern would you recommand in order to run multiple queries in parallel ?</p>
<p>Thanks in advance.</p>
<p>My use case here :</p>
<pre class="lang-js prettyprint-override"><code>import { useQueries } from '@tanstack/react-query';
import { gql } from 'graphql-request';
import { graphQLClient } from '../../graphQLClient';
export const useGetSomeStuff = (ids: string[]) =>
useQueries({
queries: ids.map((id) => ({
queryKey: ['getSomeStuff', id],
queryFn: async () =>
graphQLClient.request(
gql`
query GetSomeStuff($id: MongoObjectId!) {
oneStuff(id: $id) {
...SomeFragment
}
}
`,
{ id }
),
})),
});
</code></pre>
<p>generates :</p>
<pre class="lang-js prettyprint-override"><code>export type GetSomeStuffQueryVariables = Exact<{
id: Scalars['MongoObjectId'];
}>;
export type GetSomeStuffQuery = {
__typename?: 'Query';
// ... generated query
};
export const GetSomeStuffDocument = `
query GetSomeStuff($id: MongoObjectId!) {
oneStuff(id: $id) {
...SomeFragment
}
}`;
export const useGetSomeStuffQuery = <
TData = GetSomeStuffQuery,
TError = unknown
>(
client: GraphQLClient,
variables: GetSomeStuffQueryVariables,
options?: UseQueryOptions<GetSomeStuffQuery, TError, TData>,
headers?: RequestInit['headers']
) =>
useQuery<GetSomeStuffQuery, TError, TData>(
['GetSomeStuff', variables],
fetcher<
GetSomeStuffQuery,
GetSomeStuffQueryVariables
>(client, GetSomeStuffDocument, variables, headers),
options
);
</code></pre>
<p>You can see that generated code still uses <code>useQuery</code></p>

74,366,671 | <p>I want to calculate the running difference of column ['Values'] based on a binary condition in another column ['Conditions']. If condition is 0 then it calculates the difference of the current row and preceding row. If condition is 1 then it calculates the difference of the current row and the previous row where the condition was also 1 like so:</p>
<pre><code>
Values Condition Desired_Output
0 5000 1 NaN
1 5500 0 500.0
2 6700 1 1700.0
3 7100 0 400.0
4 8500 0 1400.0
5 9000 0 500.0
6 10500 1 3800.0
7 15750 0 5250.0
8 18000 1 7500.0
9 22250 0 4250.0
10 26000 0 3750.0
11 29750 0 3750.0
12 33500 0 3750.0
13 37250 0 3750.0
14 41000 1 23000.0

20 63500 0 3750.0
21 67250 0 3750.0
22 71000 0 3750.0
23 74750 0 3750.0
24 78500 0 3750.0
25 82250 1 22500.0
26 86000 0 3750.0
27 89750 1 7500.0
</code></pre>
<p>I tried using the groupby function with no such luck.</p>
<pre><code>df.insert(2, 'Difference', (df.groupby('Condition')['Values'].diff()))
</code></pre>
<p>When I filter the dataframe based on the conditions and calculate the difference then I get close to the desired output however I have to work with two columns in that case. Is there a way to perform this function in a single column? I am fairly new to Python and would appreciate some help</p>

74,366,672 | <p>I need to get the latest row of each combinations of sender_id & receiver_id</p>
<p>my <code>messaging</code> table:</p>
<pre><code>CREATE TABLE messaging (
msg_id SERIAL,
sender_id BIGINT NOT NULL ,
receiver_id varchar(255) NOT NULL ,
msg text default NULL,
media_link TEXT DEFAULT NULL,
sent_time TIMESTAMP NOT NULL DEFAULT NOW(),
received_time TIMESTAMP default NULL,
msg_type ENUM('text','link','file') default 'text',
is_seen BINARY DEFAULT 0
) ENGINE=InnoDB;
</code></pre>
<p>Sample data:</p>
<pre><code>+------+---------+-----------+---------------+----------+-------------------+-------------+--------+-------+
|msg_id|sender_id|receiver_id|msg |media_link|sent_time |received_time|msg_type|is_seen|

+------+---------+-----------+---------------+----------+-------------------+-------------+--------+-------+
</code></pre>
<p>ORDER BY latest with each sender_id receiver_id combination the result should look like this:</p>
<pre><code>+------+---------+-----------+---------------+----------+-------------------+-------------+--------+-------+
|msg_id|sender_id|receiver_id|msg |media_link|sent_time |received_time|msg_type|is_seen|

+------+---------+-----------+---------------+----------+-------------------+-------------+--------+-------+
</code></pre>
<p>I have tried this statement:</p>
<pre><code>SELECT msg_id,
sender_id,
receiver_id,
msg,
media_link,
sent_time,
received_time,
msg_type,
is_seen
FROM messaging
WHERE sender_id = 10 OR receiver_id = 10
GROUP BY sender_id,receiver_id
ORDER BY msg_id DESC;
</code></pre>
<p>which gives there rows ascending order of each group:</p>
<pre><code>+------+---------+-----------+---+----------+-------------------+-------------+--------+-------+
|msg_id|sender_id|receiver_id|msg|media_link|sent_time |received_time|msg_type|is_seen|
+------+---------+-----------+---+----------+-------------------+-------------+--------+-------+
|3 |7 |10 |hi |NULL |2022-11-08 19:13:13|NULL |text |0 |
|1 |1 |10 |hi |NULL |2022-11-08 19:11:53|NULL |text |0 |
+------+---------+-----------+---+----------+-------------------+-------------+--------+-------+
</code></pre>
<p>But it is only showing oldest row of each group by combination.</p>
<p>I am still learning Mysql. Please help me</p>

74,366,707 | <p>I'm working on the Library App as part of the Odin Project self-taught full stack course. Nearly done, just trying to get my data to show up as a table.</p>
<p><strong>What I expect:</strong> When I hit "submit book", I want the data to populate the table, even if no table currently exists.
(see line 98-99 of the js)</p>
<pre><code>clearTable();
document.getElementById('table-container').appendChild(buildTable(myLibrary));
</code></pre>
<p><strong>What I get instead:</strong> Hitting "submit book" does nothing.</p>
<p><strong>HOWEVER, and here's the weird part:</strong> If I start the page by creating a table initially with data from a placeholder array, the submit book and clearTable() functions will work as intended, and even add to the table even as you add more books, which is what I want it to do. It just looks like for some reason it is never able to make a table at all unless I start the page with
<code>document.getElementById('table-container').appendChild(buildTable(BOOKS));</code> on line 170 of javascript.</p>
<p>Code here: <a href="https://codepen.io/Krmanski/pen/BaVpNar" rel="nofollow noreferrer">https://codepen.io/Krmanski/pen/BaVpNar</a>. (You notice that a table shows up when you open this pen. That is my placeholder table with placeholder data. I ultimately want data objects constructed when the user hits the "submit book" button to populate this space instead. They currently do when this placeholder table is in place, but when you remove it, submit book no longer clears and adds data from the myLibrary Array.</p>

74,366,709 | <p>So I am trying to test if I understand lifetimes, and wanted to create a scenario that would fail at compile time. The code I came up with is below:</p>
<pre><code>#[test]
fn lifetime() {
struct Identity<'a> {
first_name: &'a str
}
let name: Identity;
{
let first: &str = "hello";
name = Identity {
first_name: first
};
}
println!("{}", name.first_name);
}
</code></pre>
<p>the reasoning is that instance of <code>Identity</code> should live as long as what <code>first_name</code> refrences.</p>
<p>Then in the code I create <code>let first: &str = "hello"</code> with a smaller scope, set it to <code>let name: Identity;</code> and then after <code>first</code> should have gone out of scope, I then attempted to print <code>name.first_name</code>. I was expecting this not to compile,, but it compile fine.</p>
<p>What am I missing in my understanding of how lifetimes work and why did this compile?</p>
<p>#Edit</p>
<p>updating the code to have this instead made the compilation fail:</p>
<pre><code> let string = String::from("hello");
let first: &str = string.as_str();
</code></pre>
<p>still curious to know why the original code worked.</p>

74,366,747 | <p>I've looked into Heap's algorithm for generating permutations, and all the numerous results on here for similar questions.</p>
<p>But they all seem to want every permutation where the input can be shuffled around as much as it wants to be.</p>
<p>I'd like a function that returns all possible substrings where the order remains the same so for input "abc" the result should not include "cba" for instance.</p>
<p>Here's what I mean:</p>
<p><code>getAllSubstrings("abcdefg")</code> should return:</p>
<pre><code>[
"a","b","c","d","e","f","g"
"ab","cd","ef", //"g"
"bc","de","fg", //"a"
"abc","def", //"g"
"bcd","efg", //"a"
"cde", //"fg", "ab"
"abcd", //"efg"
"bcde", //"a","fg"
"cdef", //"ab", "g"
"defg", //"abc"
"abcde", //"fg"
"bcdef", //"a""g"
"cdefg", //"ab"
"abcdefg"
]
</code></pre>
<p>Using <code>Set</code> to throw away the duplicate values is perfectly fine. I just can't wrap my head around how you would achieve the above. And it seems pretty simple...</p>
<p>Anyone got any good ideas for how one can achieve this?</p>

74,366,752 | <p>I have a matrix that shows flight data and travellers names, with totals to show how many passengers are on each flight. I need to be able to filter this table down by the row totals so that only those with 2+ travellers are shown, but I cannot figure out how to do so since the count will always show as 1 for each line.

</code></pre>
<p>My project is divided into 5 packages: main class package(TestProject), POJOs, controllers, services, and repositories. I currently one have one, simple table I'm working with that stores a user's name, and "password" This is my main class called TestProjectApplication:</p>
<pre><code>@EntityScan("com.cg.POJOs")
@EnableJpaRepositories("com.cg.repositories")
@SpringBootApplication
public class TestProjectApplication {
public static void main(String[] args) {
SpringApplication.run(TestProjectApplication.class, args);
}
</code></pre>
<p>My User POJO, and the UserRepo repository:</p>
<pre><code>import javax.persistence.*;
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
private String name;
private String password;
public User() {}
public User(int id, String name, String password)
{
super(); //OPTIONAL?
this.id = id;
this.name = name;
this.password = password;
}
...Getters, Setters, toString
</code></pre>
<pre><code>import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface UserRepo extends JpaRepository<User,Integer> {
}
</code></pre>
<p>These have been largely unchanged, as they are pretty standard. Where it gets a little more confusing, and I have tried every type of and combination of Spring Boot annotations to no avail, is my UserServices interface, the UserServicesImpl implementation, and the UserController.</p>
<p>UserServices and UserServicesImpl:</p>
<pre><code>#UserServices:
import java.util.List;
public interface UserServices {
// Save operation
User saveUser(User user);
// Read operation
List<User> fetchUserList();
// Update operation
User updateUser(User user, int userId);
// Delete operation
void deleteUserById(int userId);
}
#userServicesImpl:
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Service;
@Service
public class UserServicesImpl implements UserServices{
@Autowired
private UserRepo userRepo;
@Override
public User saveUser(User user) {
return userRepo.save(user);
}
@Override
public List<User> fetchUserList() {
return (List<User>)userRepo.findAll();
}
...updateUser(User user), deleteUserById(int id) are implemented.
</code></pre>
<p>And finally my controller class with a few test operations:</p>
<pre><code>import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.*;
@RestController
public class UserController {
@Autowired
private UserServices userServices;
// Save operation
@PostMapping("/users")
public User saveUser(@RequestBody User department)
{
return userServices.saveUser(department);
}
// Read operation
@GetMapping("/users")
public List<User> fetchUserList()
{
return userServices.fetchUserList();
}
// Read operation
@GetMapping("/test")
public List<User> fetchUsers()
{
return Arrays.asList(
new User(12, "Carlos","123123"),
new User(2, "donald","123456")
);
}
</code></pre>
<p>ALL requests I make, simply return a 404 "Not Found" error. An example request would be "GET http://localhost:1111/test". The last bit of information I could possibly show that might show my mistake, is my application.properties file.</p>
<pre><code>spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.show-sql: true
spring.datasource.username=root
spring.datasource.password=123456
spring.jpa.hibernate.ddl-auto=update
server.port = 1111
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
</code></pre>
<p>Any ideas as to why it's not working would be greatly appreciated! Using Spring Boot 2.7.5 with Java 11 on the Spring Tool Suite IDE.</p>

74,366,772 | <p>I have a column <strong>number</strong> containing number and NaN.
I want to add a column <strong>label</strong> identifying by 1 and 0 the "zones" where we have a number: the zone includes adjacents (above and below) rows.</p>
<p>The result should look like below:</p>
<pre><code>Number Label
Nan 0
Nan 1
4 1
Nan 1
Nan 0
Nan 0
Nan 1
8.9 1
Nan 1
Nan 0
Nan 0
Nan 1
47 1
</code></pre>
<p>I came up with the following solution.
But it's ugly and it wound not scale if I wanted to Label more adjacent cells ( above + 2 below).</p>
<pre><code>import numpy as np
import pandas as pd
pd.set_option('display.max_rows', 100)
#Generating our DataFrame and ensuring there are some NaN
df = pd.DataFrame(np.random.randn(100), columns=['number'])
df.loc[df.number<1] = np.nan
#diffusing the values on adjacent cells and summing
df['label'] = df.number.fillna(0)
+ df.number.shift(1).fillna(0)
+ df.number.shift(-1).fillna(0)
#Replace values by 1
df.loc[df.label>0, 'label'] = 1
print(df)
</code></pre>
<p>Could anyone help me find a more elegant solution?
Maybe with a nice df.apply that I have so much difficulties using?</p>

74,366,808 | <p>The title is mostly self-explanatory. I'm trying to create a program that opens a text file based on the title a user inputs in python. However, the program doesn't print anything - it's not taking time to compute and print out the text, but instead doesn't do anything.</p>
<p>I've tried re-wording the program to not include the first function and simply ask the user for an input, but then I'm prompted with an error about the file not being in the proper directory. All I'm expecting is for it to print the contents of a file that the user specifies.
Here is my code:</p>
<pre><code>filename = 0
def get_filename():
filename = str(input("Give a file name: "))
return filename
def process_file():
reading = open(filename, "r", encoding="utf-8")
lines = reading.readlines()
for line in lines:
print(line)
def main():
get_filename()
process_file()
main()
filename.close()

<p>What's the best way to go about this in Snowflake SQL?</p>
<p>I thought I could cross join the accounts with another table that contains all months. Then I could join back to the original table and fill in any missing values within the Spend column with zeroes. But I'm unsure how to deal with the "lagging" and "leading" nulls that result from this. For example, there would be a null value for the combination of 2/1/21 and B after the cross join but that date occurs before the first occurrence of B in the original table (4/1/21) so I wouldn't want that row in my final dataset.</p>

74,366,841 | <p>I want to implement a function which takes a key k :: Either a b, and a list of
pairs. I want the keys to have two shapes. One of the shape Left l, which will perform a lookup on the left half of the pairs, and one for the right half. Both shall return the other half of the first matching pair in the list.
If no match is found, the function should return Nothing.</p>
<p>An instance of the Output with example list:</p>
<pre><code>namesAges = [("Felix", 45), ("Grace", 25), ("Hans", 57), ("Ivy", 25)]
</code></pre>
<pre><code>bidirectionalLookup (Left "Grace") namesAges == Just (Right 25)
bidirectionalLookup (Right 57) namesAges == Just (Left "Hans")
</code></pre>
<p>I've successfully defined the functions for lookupRhs as well as lookupLhs but I am not able to combine them in my "bidirectionalLookup" function. What function form do I use? ITE, case-of, pattern-matching?</p>
<p>This is one version of my attempts. I have many modifications but none gave me any results. I have a feeling that I am on the wrong track.</p>
<pre><code>namesAges = [("Felix", 45), ("Grace", 25), ("Hans", 57), ("Ivy", 25)]
lookupLhs :: Eq a => a -> [(a, b)] -> Maybe b
lookupLhs x ((l, r) : namesAges) = if x == l then Just r else lookupLhs x namesAges
lookupRhs :: Eq b => b -> [(a, b)] -> Maybe a
lookupRhs x ((l, r) : namesAges) = if x == r then Just l else lookupRhs x namesAges
bidirectionalLookup :: (Eq b, Eq a) => Either a b -> [(a, b)] -> Maybe (Either a b)
bidirectionalLookup (Left x) namesAges = lookupLhs x
bidirectionalLookup (Right x) namesAges = lookupRhs x
bidirectionalLookup _ _ = Nothing
</code></pre>
<p>I am aware that this is beginner level and that I may be completely off track (or have the answer right in front of my nose for that matter), still any kind of help will be greatly appreciated.</p>

74,366,889 | <p>new bee in Kotlin and I am trying to compile a very simple thing. I'd like to initialize an array of lists with one line of code. But I get stuck in always have to uses mutable objects and inserts unto the list.</p>
<p>Here what I have which <em>I don't like</em>. It is too complicated and many lines of code, the array does not need to be mutable in reality. It will be always the same size and same number of elements.</p>
<pre><code>val r0 = arrayListOf<Int>(1, 3, 5, 7)
val r1 = arrayListOf<Int>(10, 11, 16, 20)
val r2 = arrayListOf<Int>(23, 30, 34, 60)
val list: MutableList<ArrayList<Int>> = ArrayList()
list.add(r0)
list.add(r1)
list.add(r2)
</code></pre>
<p>That works, but I want something like</p>
<pre><code>val list2: List<ArrayList<Int>> = ArrayList(
arrayListOf<Int>(1, 3, 5, 7),
arrayListOf<Int>(10, 11, 16, 20),
arrayListOf<Int>(23, 30, 34, 60)
)
</code></pre>
<p>But this does not compile, not sure why.</p>

74,366,926 | <p>I'd like to create a dropdown in an html form that will dynamically list the next four upcoming Saturdays. The idea is that when someone is signing up they can choose which of the four upcoming Saturdays they'd like to come in to visit our space, so we can keep track and send automated email responses. The time is the same every week so that's not an issue.</p>
<p>Been trying to do this through Wordpress plugins but that's proving complicated to integrate with email software... I think it must be easier and cleaner to do it in html/javascript/php.</p>

74,366,934 | <p>I have data with several infrequent levels in each column. Find the <code>dput()</code> of a small portion of data at the bottom of the question. Here's how the data is structured;</p>
<pre><code> AppointmentMonth DayofWeek AppointmentHour EncounterType
1 Sep Mon 16 Office Visit
2 Jun Tue 13 Office Visit
3 Sep Mon 14 Procedure Visit
4 Dec Thu 14 Office Visit
5 Mar Tue 11 Office Visit
6 May Fri 14 Office Visit
7 May Tue 11 Office Visit
8 May Tue 9 Office Visit
.......

<p>When you check the frequency table of each column you will realize some levels have 0, 1, or 2 occurrences. Here is an example.</p>
<pre><code>table(data$AppointmentHour)
8 9 10 11 12 13 14 15 16 17
4 4 2 4 1 2 8 1 3 1
</code></pre>
<p>I would like to identify and remove the infrequent levels whose frequencies, let's say less than 3 (can be changed depending on the problem/data), in each column.</p>
<p>I tried @akrun's answer in <a href="https://stackoverflow.com/questions/46282359/removing-infrequent-rows-in-a-data-frame/46282408?noredirect=1#comment131205274_46282408">this question</a>. Here is the code chunk:</p>
<pre><code>library(data.table)
setDT(data)[data[, .I[.N >= 3],
by = .(AppointmentMonth, DayofWeek, AppointmentHour, EncounterType)]$V1]
</code></pre>
<p>However, this code removes the infrequent levels based on the combination of columns, not based on each individual column.</p>
<h4>Data:</h4>

74,367,019 | <p>I'm trying to extract a certain character from a buffer that isn't ASCII. I'm reading in a file that contains movie names that have some non ASCII character sprinkled in it like so.</p>
<pre class="lang-none prettyprint-override"><code>1|Tóy Story (1995)
2|GoldenEye (1995)
3|Four Rooms (1995)
4|Gét Shorty (1995)
</code></pre>
<p>I was able to pick off the lines that contained the non ASCII characters, but I'm trying to figure out how to get that particular character from the lines that have said non ASCII character and replace it with an ACSII character from the map I've made.</p>
<pre><code>import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
public class Main {
public static void main(String[] args) {
HashMap<Character, Character>Char_Map = new HashMap<>();
Char_Map.put('o','ó');
Char_Map.put('e','é');
Char_Map.put('i','ï');
for(Map.Entry<Character,Character> entry: Char_Map.entrySet())
{
System.out.println(entry.getKey() + " -> "+ entry.getValue());
}
try
{
BufferedReader br = new BufferedReader(new FileReader("movie-names.txt"));
String contentLine= br.readLine();
while(contentLine != null)
{
String[] contents = contentLine.split("\\|");
boolean result = contents[1].matches("\\A\\p{ASCII}*\\z");
if(!result)
{
System.out.println(contentLine);
//System.out.println();
}
contentLine= br.readLine();
}
}
catch (IOException ioe)
{
System.out.println("Cannot open file as it doesn't exist");
}
}
}
</code></pre>
<p>I tried using something along the lines of:</p>
<pre><code>if((contentLine.charAt(i) == something
</code></pre>
<p>But I'm not sure.</p>

74,367,021 | <p>Is there any way to search only the first line of a Multiline Textbox without knowing exactly at what position the text is you're looking for?</p>
<p>If I knew the position of the text I was looking for I could do something like:</p>
<pre><code>Dim myNotes As String = "The book has a lot of text"
Dim myText As String = "text"
If Not myNotes.Substring(0,4) = myText Then
' Do Something
End If
</code></pre>
<p>Or if I wanted to search the entire textbox I could do something like:</p>
<pre><code>Dim myNotes As String = "The book has a lot of text"
Dim myText As String = "text"
If Not myNotes.Contains(myText) Then
' Do Something
End If
</code></pre>
<p>But I want to search only the first line of the textbox and I'm not sure at what position the text may be. Is there anyway to do a search like that?</p>

74,367,070 | <p>I have written a super small logger in a typescript class and placed it in a file call <code>Log.ts</code>. The file also contains a type definition. I would like to reference it as a library so that I can create an instance of that class in the script lab script. How do I do that?</p>
<p>I have placed the <code>Log.ts</code> file on a public website and referenced it in the Libraries tab in script lab but it is not getting picked up.</p>
<p>What do I need to do to be able to create a new logger as <code>const log = new Log()</code>?</p>
<h2>Update</h2>
<p>I have tried to create a minimal example. This is now the <code>log.ts</code> file:</p>
<pre><code>export type PongType = "pong";
export class Log {
ping(): PongType {
return "pong";
}
}
</code></pre>
<p>I have compiled this to a <code>log.js</code> as:</p>
<pre><code>var Log = /** @class */ (function () {
function Log() {
}
Log.prototype.ping = function () {
return "pong";
};
return Log;
}());
export { Log };
</code></pre>
<p>I have then placed <code>log.js</code> on a public server and then tried to import it in the HTML section in script lab as suggested in the comments. This is done as:</p>
<p><code><script src="https://somedomain.com/log.js"></script></code></p>
<p>But I still don't understand how I could create an instance of <code>Log()</code> in the Script lab script.</p>

74,367,090 | <p>I want to implement an algorithm that basically moves every value(besides the last one) one place to the left, as in the first element becomes the second element, and so on.</p>
<p>I have already implemented it like this:</p>
<pre><code>for(int i = 0; i < vct.size() - 1; i++){
vct[i] = vct[i + 1];
}
</code></pre>
<p>which works, but I was just wondering if there is a faster, optionally shorter way to achieve the same result?</p>
<p><strong>EDIT</strong>: I have made a mistake where I said that I wanted it to move to the right, where in reality I wanted it to go left, so sorry for the confusion and thanks to everyone for pointing that out. I also checked if the vector isn't empty beforehand, just didn't include it in the snippet.</p>
