<p>I'm new with Redux, and I'd like to improve performances of my web app as much as possible.</p>
<p>I have a state in redux, that I store in a variable to display it later.</p>
<p>Here is the code :</p>
<pre><code>const metricsState = useSelector((state: MetricsStateObject) => state.MetricsState);
const myMetrics = metricsState.myMetrics;
</code></pre>
<p>I saw that <a href="https://www.w3schools.com/react/react_usememo.asp" rel="nofollow noreferrer">useMemo</a> improve performance by not re-render if the data did not mutate.</p>
<p>So I'm wondering if <code>const myMetrics = useMemo(() => metricsState.myMetrics, [metricsState.myMetrics]);</code> is a good practice, or totaly useless ?</p>
<p>Thank you for your time.</p>

<pre><code>::tm tm{0, 0, 0, 29, 10, 2022 - 1900, 0, 0}; // 10 for November

<p>Above code outputs <code>1669660200000</code>, which is equivalent to <strong>2022 November 29, 00:00:00</strong>. But it is in local timezone. How to get the UTC time for the aforementioned date?<br />

<p>I'm using DOMMatrix to set transform on a canvas context, but I am not sure how to "fix" the translation after the rotate. Currently the code I've written rotates an image around a given point on the canvas, which works fine. The issue is after the rotation, the translate moves relative to the rotation, which is not what I want. I want the translation to be relative to the canvas.</p>
<p><a href="https://codesandbox.io/s/beautiful-frog-zxqcdh?file=/src/index.js" rel="nofollow noreferrer">CodeSandbox demo</a></p>
<p>I implemented this function which I read "fixes" the translation after rotation, but it doesn't seem to do what I need:</p>
<pre class="lang-js prettyprint-override"><code>function rotate(x, y, rotation) {
const panXX = x * Math.cos((rotation * Math.PI) / 180);
const panXY = y * Math.sin((rotation * Math.PI) / 180);
const panYY = y * Math.cos((rotation * Math.PI) / 180);
const panYX = x * Math.sin((rotation * Math.PI) / 180);
const panX = panXX + panXY;
const panY = panYY - panYX;
return { x: panX, y: panY };
}
</code></pre>
<p>Is there a way of doing this, either by modifying the <code>rotate</code> function above, or the <code>DOMMatrix</code>, or a different way entirely?</p>

<p>I have this relationship</p>
<pre><code>Class Item(models.Model):
pass
Class Category(models.Model):
items = models.ManyToManyField(Item)
</code></pre>
<p>I can define the field name as <code>items</code> for category and access it via <code>category.items</code> but I want to define a field name for Item too as <code>item.categories</code> rather than the default <code>item.category</code></p>
<p>How can I achieve it?</p>
<h3>Update</h3>
<p>Tried</p>
<p><code>items = models.ManyToManyField(Item, related_name = "categories")</code></p>
<p>But I get</p>
<p><code>TypeError: Direct assignment to the reverse side of a many-to-many set is prohibited. Use categories.set() instead.</code></p>
<p>on <code>Item.object.create(**data)</code></p>

<p>I have two tables of users and articles and I want to count how many new users and how many new articles I have in the past 7 days.</p>
<p>tbl_users:</p>

<p>This query works now but it's slow and long. Please help me fix this query (I know it's bad) and if it's possible to add diff columns for both counters:</p>
<p>(Please go easy on me with the comments)</p>
<pre><code>select articles.days_back,articles.count, users.count as users from (

<p>I would like to change the values of this list by alternating the 0 and 1 values in a checkerboard pattern.</p>
<pre><code>table =
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
</code></pre>
<p>i tried:</p>
<pre><code>for i in range(len(table)):
for j in range(0, len(table[i]), 2): # ho definito uno step nella funzione range
table[i][j] = 0
</code></pre>
<p>but for each list the count starts again and the result is:</p>
<pre><code>
0 1 0 1 0
0 1 0 1 0
0 1 0 1 0
0 1 0 1 0
0 1 0 1 0
</code></pre>
<p>my question is how can I change the loop to form a checkerboard pattern.</p>
<p>I expect the result to be like:</p>
<pre><code> 0 1 0 1 0
1 0 1 0 1
0 1 0 1 0
1 0 1 0 1
0 1 0 1 0

<p>I am putting together some summary stats of a dataframe about biomass at different sights. Here's some dummy data:</p>
<pre><code>df1 <- data.frame(ID = c(1, 2, 3, 4, 5,6,7,8,9,10,11),
Reach = c('a', 'b', 'c', 'a', 'a', 'b', 'c', 'c','b','c','a'),
Bio = c(12, 11, 10.4, 10, 12.5, 14, 12, 17, 17.5, 17.3, 16.2))
</code></pre>
<p>I have created a table in which to capture summary stats:</p>
<pre><code>sumstats<- data.frame(matrix(data=NA, nrow=1, ncol=4))
colnames(sumstats) <- c("Total.Fish", "Mean.Fish", "St.Dev", "95%.Conf")
</code></pre>
<p>Completing the first three columns is easy enough</p>
<pre><code>sumstats$Total.Fish<- sum(df1$Bio)
sumstats$Mean.Fish<- mean(df1$Bio)
sumstats$St.Dev <- sd(df1$Bio)
</code></pre>
<p>But the last one is giving me some bother. To my understanding there isn't a function in base R which computes the 95% confidence level. I have found that I can compute it using a Z Test in BSDA:</p>
<pre><code>library(BSDA)
test1<- z.test(df1$Bio, sigma.x=(mean(df1$Bio)), conf.level = 0.95)
</code></pre>
<p>But I cannot figure out how to get the outputs of that into my dataframe. The output of the Z test is a list, one of the list items is the confidence level.</p>
<p>If I print the confidence level line of that list it shows several number, my summary stats dataframe needs the first one (5.74217 in this case).
So my question is either:</p>
<ol>
<li>how do I get just part of the outputs from the z test into my dataframe</li>
<li>is there an easier way to calculate the 95% condeince level?</li>
</ol>

<p>I have a dataframe (df_obs) indexed by date containing one column with a length in number of days of something being observed:</p>
<pre><code>Date duration
2012-01-01 3
2013-04-01 26
2014-05-01 14
2016-01-01 297
</code></pre>
<p>I am trying to repurpose this dataframe to provide a binary indication of whether an observation happens on each day, so the result would look like this:</p>
<pre><code>Date Obs
2012-01-01 1
2012-01-02 1
2012-01-03 1
2012-01-04 0
2012-01-05 0
</code></pre>
<p>I had a script to do this, but since performing updates it won't wor - this is what I had used before:</p>
<pre><code>Time = pd.DataFrame(pd.date_range(start='01/01/2012', end='31/12/2019'))
obs = np.zeros()
for d in df_obs.itertuples():
ilong = np.argwhere(Time.date == d.Index)[0][0]
obs[ilong:ilong+d.duration] = 1
</code></pre>
<p>This now returns the following error:</p>
<pre><code>ValueError: Length of values (1) does not match length of index (2921)
</code></pre>
<p>Any pointers of what edits I need to make this work?</p>

<p>I am trying to read a tif file using <code>terra</code> r package using the following code</p>
<pre><code>hh <- rast("imagery_HH.tif")

<p>Using the function <code>terra::describe("imagery_HH.tif")</code>, I got the following information:</p>

<p>If we look closely, we can see that the coordinate reference is missing and the resolution is showing 1 x 1 with the incorrect extent. But if we open the tif file in QGIS, it shows the following properties having a crs of EPSG:4326</p>

<p>I would like to insert rows of the year 1997, 1999 and 2001 for every country in the current dataset such that we would have something like:</p>
<pre><code>Country Year Politics
Afghanistan 1996 Value 1
Afghanistan 1997 empty value
Afghanistan 1998 Value 2
....
....
....
Albania 1996 Value 3
Albania 1997 empty value
etc
etc
</code></pre>
<p>Is there maybe another way because my original dataset looks as follows:
<a href="https://i.stack.imgur.com/t5kfF.png" rel="nofollow noreferrer">Original dataset</a></p>
<p>The conclusion is that I want to make the current dataset fitted to the original dataset and currrently this is not possible as the original dataset has the years 1997, 1999 and 2001 whereas the current dataset did not include these years.</p>
<p>I hope that I have given a clear explanation of what I would like to see.</p>

<p>I created a script in JavaScript to take value from one input and place it in several inputs, but I have a problem that value is only put in the first input.</p>
<p>The JavaScript code is:</p>
<pre><code>jQuery(document).ready(function ($) {
var $apartament = $('#value-apartament'),
$permetru = $('#put-value');
$apartament.on('input', function () {
$permetru.val($apartament.val());
});
});
</code></pre>
<p>The first input have the id: <code>#value-apartament</code> and the others have <code>#put-value</code> for copy the value from the first input and put for the rest of three.</p>

<p>I want to create a dropdown menu using javaScript, however I have created a dropdown list using an array, but I am struggling to add the mouseOver event such that, when a user over a specific list item, the list item color changes to lightpink, bg color to black and shows a cursor pointer.</p>
<p>Finally , When I tried to click the button it always renders list item every time I click, I want to show a toggle effect, such that when a user click's button , show list items, then hide the same with the selected item.</p>
<p>I tried to add certain functionality but I do not know what went wrong. Can anyone please correct me?</p>
<p>Any help or suggestions are helpful.</p>
<p>Thanks</p>
<p>Please see the code below which I have tried:</p>
<p><strong>HTML</strong></p>
<pre><code><div class="dropdownMain">
<button id="dropdownBtn" class="dropdwonBtn"> Select Counrtry</button>
<div id="dropdownList" class="dropdownList">
</div>
</div>
</code></pre>
<p><strong>JavaScript</strong></p>
<pre><code>const countries = ["India", "Ireland", "USA", "UK"];
const dropdownBtn = document.getElementById("dropdownBtn");
const dropdownList = document.getElementById("dropdownList");
dropdownBtn.addEventListener("click", () => {
for (let i = 0; i < countries.length; i++) {
const list = document.createElement("li");
list.style.color = "#ff0000";
list.style.listStyleType = "none";
list.style.padding = "0.5rem";
list.style.paddingLeft = "1.1rem";
list.style.borderRadius = "5px";
list.style.marginBottom = "0.2rem";
list.style.marginTop = "0.2rem";
// only should trigger when hover over list item
list.addEventListener(
"mouseover",
(e) => {
e.target.style.color = "black";
e.target.style.backgroundColor = "lightpink";
e.style.cursor = "pointer";
// reset the color after a short delay
setTimeout(() => {
e.target.style.color = "";
}, 500);
},
false
);
list.appendChild(document.createTextNode(countries[i]));
dropdownList.appendChild(list);
}
});
</code></pre>
<p>Please see codepen demo here <a href="https://codepen.io/tapesh02/pen/ExRpgZb" rel="nofollow noreferrer">https://codepen.io/tapesh02/pen/ExRpgZb</a></p>

<p>Using sklearn, I have just finished training, tuning hyperparameters and testing a Random Forest Multiclass Classifier using RandomizedSearchCV. I have obtained the best parameters, best score and so on. This was all done with a labelled dataset. Now I want to apply this classifier onto an unlabelled dataset (meaning there are only the features and no classes) to make class/label predictions.</p>
<p>How do I go about doing this?</p>
<p>I haven't tried anything yet because I am stuck.</p>

<p>I am trying to analyze an earnings call using python regular expression.
I want to delete unnecessary lines which only contain the name and position of the person, who is speaking next.</p>
<p>This is an excerpt of the text I want to analyze:</p>
<p>"Questions and Answers\nOperator [1]\n\n Shannon Siemsen Cross, Cross Research LLC - Co-Founder, Principal & Analyst [2]\n I hope everyone is well. Tim, you talked about seeing some improvement in the second half of April. So I was wondering if you could just talk maybe a bit more on the segment and geographic basis what you're seeing in the various regions that you're selling in and what you're hearing from your customers. And then I have a follow-up.\n Timothy D. Cook, Apple Inc. - CEO & Director [3]\n ..."</p>
<p>At the end of each line that I want to delete, you have [some number].</p>
<p>So I used the following line of code to get these lines:</p>
<p><code>name_lines = re.findall('.*[\d]]', text)</code></p>
<p>This works and gives me the following list:
['Operator [1]',
' Shannon Siemsen Cross, Cross Research LLC - Co-Founder, Principal & Analyst [2]',
' Timothy D. Cook, Apple Inc. - CEO & Director [3]']</p>
<p>So, now in the next step I want to replace this strings in the text using the following line of code:</p>
<pre><code>for i in range(0,len(name_lines)):
text = re.sub(name_lines[i], '', text)
</code></pre>
<p>But this does not work. Also if I just try to replace 1 instead of using the loop it does not work, but I have no clue why.</p>
<p>Also if I try now to use re.findall and search for the lines I obtained from the first line of code I don`t get a match.</p>

<p>I have the following dataframe called df (<code>dput</code> below):</p>
<pre><code> group indicator value
1 A FALSE 2
2 A FALSE 1
3 A FALSE 2
4 A TRUE 4
5 B FALSE 5
6 B FALSE 1
7 B TRUE 3
</code></pre>
<p>I would like to remove the non-last rows with <code>indicator == FALSE</code> per group. This means that in df the rows: 1,2 and 5 should be removed because they are not the last rows with FALSE per group. Here is the desired output:</p>
<pre><code> group indicator value
1 A FALSE 2
2 A TRUE 4
3 B FALSE 1
4 B TRUE 3
</code></pre>
<p>So I was wondering if anyone knows how to remove non-last rows with certain condition per group in R?</p>
<hr />
<p><code>dput</code> of df:</p>
<pre><code>df <- structure(list(group = c("A", "A", "A", "A", "B", "B", "B"),
indicator = c(FALSE, FALSE, FALSE, TRUE, FALSE, FALSE, TRUE
), value = c(2, 1, 2, 4, 5, 1, 3)), class = "data.frame", row.names = c(NA,
-7L))
</code></pre>

let alertMessage = "Please use Google Chrome to access this site.\nSome key features do not work in browsers other than Chrome."
if(notChrome) alert(alertMessage)

<p>Firstly ,I was doing <code>cy.contains(option)</code> with it was clicking the exact value eg -I want to click <code>One</code> but <code>One One</code> is also there so <code>cy.contains</code> not working.</p>
<p>I tried Regex but it is not working</p>
<p>I am trying to click the exact match from drop down writing test step as ;</p>
<pre class="lang-js prettyprint-override"><code>cy.contains(new RegExp(option, "g"))
</code></pre>
<p>but not giving me correct output. I am getting error : <code>Timed out retrying after 4000ms: Expected to find content: 'option' but never did.</code></p>

<p>Hy! I have a dataframe with two columns latitude and longitude with a wrong format that i want to correct. The structure of de strings in columns is the next</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Lat</th>
<th>Long</th>
</tr>
</thead>
<tbody>
<tr>
<td>-314193332</td>
<td>-6419125129999990</td>
</tr>
<tr>
<td>-313147283</td>
<td>-641708031</td>
</tr>
</tbody>
</table>
</div>
<p>I need to append a point in the third position to have this structure:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Lat</th>
<th>Long</th>
</tr>
</thead>
<tbody>
<tr>
<td>-31.4193332</td>
<td>-64.19125129999990</td>
</tr>
<tr>
<td>-31.3147283</td>
<td>-64.1708031</td>
</tr>
</tbody>
</table>
</div>
<p>how can i do this?</p>
<p>the value being an integer type too, i can configure that if there is a function to edit integers</p>

m.logout()
messages.success(request, f'Subscribers list sychronized successfully.')

</code></pre>
<p>I'd like to place 3 buttons on my front-end that call this same function with different arguments each time, for example one button get_emails(FU_HOST, FU_USERNAME, FU_PASSWORD), the other button get_emails(USV_HOST, USV_USERNAME, USV_PASSWORD).</p>
<p>How can one achieve this in Django? My credentials are stored in .env file.</p>

<p>How can I convert a mutable u8 pointer to a mutable reference of another type?</p>
<pre class="lang-rs prettyprint-override"><code>let ptr: *mut u8;
let reference: &mut SomeType = ?; // What should i do here?
</code></pre>
<p>I have found a sort-of viable solution, but I wonder if there is a better way:</p>
<pre class="lang-rs prettyprint-override"><code>let reference = unsafe { &mut *(ptr as *mut SomeType) };

<p>I am using Amazon's sample code to connect to my S3 bucket. I have changed the key and bucket name for that of my bucket in S3. I have tried using the standard bucket name and using access points however I am still getting the following error.</p>
<pre><code>Error CredentialsProviderError: Could not load credentials from any providers
</code></pre>
<p>I am unsure what exactly this error is saying I have missed, and also what credentials I need and how to recieve them.</p>
<p>I am relatively new to AWS so any help would be much appreciated.</p>
<p>I am running my code to access the bucket on an EC2 instance within the same VPC as the bucket so I was assuming I would not need additional permissions or credentials.</p>
<p>I am relatively new to AWS so any help would be much appreciated.</p>

<p>I have a list of scripts doing their own thing (they are actually Rscripts reading modifying and writing files) like this:</p>
<pre><code>## Script 1
echo "1" > file1.out
## Script 2
echo "2" > file2.out
## Script 3
echo "3" > file3.out
</code></pre>
<p>These are saved in different scripts as follow:</p>
<pre><code>## Writing script 1
echo "echo \"1\" > file1.out" > script1.task
## Writing script 2
echo "echo \"2\" > file2.out" > script2.task
## Writing script 3
echo "echo \"3\" > file3.out" > script3.task
</code></pre>
<p><strong>Is there a way to run all these scripts in parallel using the file names?</strong>
In a loop it'd look like this:</p>
<pre><code>for task_file in *.task
do
sh ${task_file}
done
</code></pre>

<p>I am trying to extract the colour (Farve) from this text string.
I can't seem to make the extraction either stop, or start the right place.
Also, the length of the target extraction will vary, as colours of course are varying length name.
The picture is of the target texted, wanted in the cell.</p>
<p>Hope some might be able to help, thank you.
<img src="https://i.stack.imgur.com/B8wRR.png" alt="enter image description here" /></p>
<p>I have tried multiple solutions of Len, left, right combination as well as trim, index combination and regexetraxt.</p>

<p>When I try to run the app without the folder in there, it crashes due to missing dependencies.</p>

<p>But I cannot find a way to group the data in that way.</p>

<p>From a Google Codelab (can't remember which one), they adviced doing the following for fragments:</p>
<pre><code>class MyFragment : Fragment() {
private var _binding: MyFragmentBinding? = null
private val binding get() = _binding!!
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?
): View {
_binding = MyFragmentBinding.inflate(inflater, container, false)
return binding.root
}
override fun onDestroyView() {
super.onDestroyView()
_binding = null
}
}
</code></pre>
<p>And then accessing the views with e.g. <code>binding.button1</code>.</p>
<p>Is there a specific reason for doing it like this, with <em>_binding</em> and <em>binding</em>? Are there better methods? Perhaps an extension for Fragments - like a BaseFragment - to avoid code duplication.</p>

<p>I have a list with 72 bounding boxes. This is the dput (just 5 of them).</p>
<pre><code>list(`1` = c(V1 = 7.426758, V2 = 47.398349, V3 = 7.8508356, V4 = 47.686178
), `10` = c(V1 = 7.8508356, V2 = 47.686178, V3 = 8.2749132, V4 = 47.974007

</code></pre>
<p>and this is the desired output:</p>
<pre><code>c(7.4267580,47.3983490,7.8508356,47.6861780)
</code></pre>
<p>How can I print each bounding box in the desired output using a for loop?</p>

<p>What I want to implement is like this style. Pls see the picture below.
<a href="https://i.stack.imgur.com/dXy9B.png" rel="nofollow noreferrer">Need show</a></p>
<p>The border is gradient, start color is</p>
<pre><code>#08FFFB
</code></pre>
<p>and the end color is</p>
<pre><code>#FF4EEC
</code></pre>
<p>.And the background which like black is also gradient which start color is</p>
<pre><code>#3A3A3A
</code></pre>
<p>and the end color is</p>
<pre><code>#0B0B0B
</code></pre>
<p>The corner radius is 16.</p>
<p>I want to use it as a custom indicator in TabBar component. So, I custom the</p>
<pre><code>indicator
</code></pre>
<p>like this.</p>
<pre><code>
@override
Widget build(BuildContext context) {
List\<String\> list = \["全部","读书","电影", "小说"\];
return Padding(
padding: EdgeInsets.fromLTRB(15, 0, 15, 0),
child: Container(
width: double.infinity,
height: 62,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.all(Radius.circular(20))),
child: Padding(
padding: EdgeInsets.fromLTRB(25, 13, 25, 13),
child: TabBar(
labelColor: Colors.white,
unselectedLabelColor: YYSColors.yysTextColor(),
isScrollable: true,
indicator: new BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
colors: \<Color\>\[
Color(int.parse("FF3A3A3A", radix: 16)),
Color(int.parse("FF2B2B2B", radix: 16))
\],
),
borderRadius: BorderRadius.circular(16),
border: new Border.all(
color: Color(int.parse("FF08FFFB", radix: 16)), width: 2),
),
tabs: list
.map((String arenaType) {
return Tab(text: arenaType);
}).toList(),
),
),
),
)，
);
}
</code></pre>
<p>I have tried to use image in BoxDecoration but it is not work. And I also get some informations from internet that maybe I can use a custom Widget extends Decoration, but I need to override paint() method. It is too difficulty to me. So I came here to ask for help. Thanks a lot.</p>
<p>It is my frist question at here. So the format is not that good. Pls forgive me.</p>

<p>I have a simple map as below</p>
<pre><code>val myMap = Map("A" -> "AB300","B" -> "XI134","C" -> null)
</code></pre>
<p>I would like to validate the length of a particular key and would like to return the value as string (and not as <code>Option</code> . I tried the following</p>
<pre><code>myMap.getOrElse("A",null).toString.length
val res50: Int = 5
</code></pre>
<p>This works fine. But obviously, doesn't handle for null data</p>
<pre><code>myMap.getOrElse("C",null).toString.length
//Null pointer Exception
</code></pre>
<p>Is there a way to handle null too? The expectation is length for a null value should return zero (may be replacing null with space or something)</p>

<p>I have a hard drive with thousands of images from a camera-trap proyect. I've used a software that detects in which photos there is an animal. From that I've got a .csv with one column per photo "tagged" with the full directory of each photo</p>
<pre><code>| Column A |
| -------- |
| E:\Imagenes\2-1\VK1050_01\VK1050_01_1\**MFDC0421.JPG** |
| E:\Imagenes\2-1\VK1050_01\VK1050_01_1\MFDC0422.JPG |
.....
| E:\Imagenes\2-1\UJ8090_01\UJ8090_01_1\**MFDC0421.JPG** |
</code></pre>
<p>The source hard drive have several folders and subfolders (season, site, etc), that I would like to keep (but with only the tagged fotos from the list inside)
Note that as the photos come from diferent cameras the photos names are the same sometimes, but in different folders.</p>
<p>For that I'm using the following code in R:</p>
<pre><code>tagged_img <- read.csv(file.path(dir, "images_filtered.csv"), header = TRUE, sep = ";")
from <- tagged_img$file_path
to <- "E:/"
</code></pre>
<p>file.copy(from, to, recursive=TRUE, copy.date=TRUE)</p>
<p>The code runs and the list "from" contains every image i want to copy) but the copy I get has no folders or subfolders, and only 20000 photos out of 150000 are copied. I've noticed that the copied photos have unique names: e.g. there's only one IMG0001.jpg whereas in the .csv file with the list I have several photos named IMG0001.jpg</p>
<p>Any way to fix these and keep the folders and copy all the files?
Thanks!</p>

<p>So I'm running an app with nodejs + express, and trying to connect to the prismic API. keep getting " '[Link resolver error] Unknown type\n' ", I understand from the message it's something about my routes but I'm unsure how to fix it</p>

the issue was I was trying to render page, instead of pages/home</p>
<pre><code>app.get('/', async (req, res) => {
const document = await client.getFirst()

})

<p>I am using a code for a query, sometimes the input goes and there is no return (basically it does not find anything so the return is an empty row) so it is empty. However, when I use <code>pd.concat</code>, those empty rows disappear. Is there a way to keep these no return rows in the loop as well so that when I use that I can have empty rows on the final <code>output.csv</code>?</p>
<pre class="lang-py prettyprint-override"><code>import numpy as np
import pandas as pd
from dl import authClient as ac, queryClient as qc
from dl.helpers.utils import convert
import openpyxl as xl
wb = xl.load_workbook('/Users/somethingfile.xlsx')
sheet = wb['Sheet 1']
df = pd.DataFrame([],columns = ['col1','col2',...,'coln'])
for row in range(3, sheet.max_row + 1):
a0, b0, r = sheet.cell(row,1).value, sheet.cell(row,2).value, 0.001
query = """
SELECT a,b,c,d,e FROM smthng
WHERE q3c_radial_query(a,b,{:f},{:f},{:f}) LIMIT 1
""".format(a0,b0,r)
response = qc.query(sql=query,format='csv')
temp_df = convert(response,'pandas')
df = pd.concat([df,temp_df])
df.to_csv('output.csv')

<p>When I check the official Tailwind CSS documentation, it says that</p>
<blockquote>
<p>Use w-screen to make an element span the entire width of the viewport.</p>
</blockquote>
<p>I mean, w-screen is ok when I try to implement</p>
<pre><code>width: 100vw;
</code></pre>
<p>But what should I do when I try to implement</p>
<pre><code>width: 90vw;
height: 90vh;
</code></pre>

<p>Suppose you have a table with an user id and date+time (for simplicity in steps of 1 hour)</p>
<p>The table here is ordered by agent and time stamp.</p>

<p>I found some code samples with <code>dense_rank</code> and <code>row_number</code> but didn't got a result that was expected.</p>
<p>I have a solution running over each record in the source table and and creating the result table, but it is slow.</p>
<p>The query has to run on a SQL 2012 or later.</p>

<p>I'm trying to install the MySQLdb package for python3, because I need to use mysql for a project I'm currently doing.
But I can't get that package and work with it</p>
<p>I have tried the following things:</p>
<p>When I try to import it, I get this error:</p>
<pre><code>python3 Get_Acess_and_Refresh_Tokens.py
Traceback (most recent call last):
File "/home/*****/Desktop/*****/Get_Acess_and_Refresh_Tokens.py", line 6, in <module>
from MySQLdb import _mysql
ModuleNotFoundError: No module named 'MySQLdb'
</code></pre>
<p>When I try to install python-mysqldb I get this message:</p>
<pre><code>~$ sudo apt-get install python-mysqldb
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package python-mysqldb is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'python-mysqldb' has no installation candidate`
</code></pre>
<p>When I try to apt-get update I get this: I have just copied some errors because it detects them as spam</p>
<pre><code>$ sudo apt-get update
Err:2 http://es.archive.ubuntu.com/ubuntu jammy InRelease
Temporary failure resolving 'es.archive.ubuntu.com'
Reading package lists... Done
W: Failed to fetch http://es.archive.ubuntu.com/ubuntu/dists/jammy/InRelease Temporary failure resolving 'es.archive.ubuntu.com'
W: Some index files failed to download. They have been ignored, or old ones used instead.
</code></pre>
<p>Edit: This last part I have solved with this post: <a href="https://askubuntu.com/questions/91543/apt-get-update-fails-to-fetch-files-temporary-failure-resolving-error">https://askubuntu.com/questions/91543/apt-get-update-fails-to-fetch-files-temporary-failure-resolving-error</a>
But the problem continues with the same result</p>
<p>Anyone know what I am doing wrong and any solution/alternative to deal with it?</p>
<p>Thanks in advance</p>

<p>I have a material design table and I wrote custom functions to load the data and extract the objects from the JSON array object.</p>
<p>I have the following code:</p>
<pre><code> public getDocumentList() {
return this.http.get(this.getDocumentUrl, this.httpOptions)
.subscribe(
documentResponse => {
for (let i = 0; i > Object.keys(documentResponse).length; i++){
console.log(Object.keys(documentResponse));
console.log("documentResponse:");
console.log(documentResponse);
console.log(of(documentResponse[i]).pipe(pluck('soap:Envelope', 'soap:Body', 'ns2:getDocumentsResponse', 'return')));
this.documentList$ = of(documentResponse[i]).pipe(pluck('soap:Envelope', 'soap:Body', 'ns2:getDocumentsResponse', 'return'));
this.documentList$.subscribe(x => this.documentListArray.push(x));
console.log("Doklist", this.documentListArray)
}
this.setDokumentStatus();
},
error => {
alert('Following error happened:' + ' ' + error['statusText']);
console.log('There was an error: ', error);
});
}
</code></pre>
<p>The following public function above fills <code>documentListArray</code> with the required objects...</p>
<p>But this semi-random error gets thrown:</p>
<pre><code>ERROR Error: Uncaught (in promise): TypeError: Cannot read properties of undefined (reading 'length')
TypeError: Cannot read properties of undefined (reading 'length')
at WorkDocumentComponent.<anonymous> (work-document.component.ts:139:6
</code></pre>
<p>The last line of this code is where the error happens (before the bracket obviously):</p>
<pre><code>async FillElementDataArray() {
ELEMENT_DATA.length = 0;
this.dataSource.connect().next(ELEMENT_DATA);
let add_WorkDocument = {} as WorkDocument;
console.log(this.DataService.documentListArray);
let docsForMetadata;
// this below is undefined yo
for (let i = 0; i < this.DataService.documentListArray[0].length; i++)
{
</code></pre>
<p>...which is VERY strange.</p>
<p>Is this an async and sync function issue?</p>
<ul>
<li>How do I fix this?</li>
<li>Why is it still undefined and I cannot console.log it? EDIT: I can console.log it IF I put the console.log before the log loop.</li>
</ul>
<p>P.S. my documentResponse looks like this:</p>
<pre><code>[
{
"soap:Envelope": {
"soap:Body": {
"ns2:getDocumentMetaDataResponse": {
"return": {
"items": [
{
"key": "blah",
"values": "blablabla"
and so on...
}
]

<p>I cannot seem to work out how to do this - I am very new to Javascript/Typescript and even React.</p>
<p>I have all the Tabs working showing the correct details in each, but I cannot pull the child JSX 'DesignForm' and make it show as within the First Tab.</p>
<pre><code>import React, { Children } from "react";
import { Card, Page, Layout, TextContainer, Image, Stack, Link, Heading, Tabs} from "@shopify/polaris";

export function NavTabs() {
const [selected, setSelected] = useState(0);
interface childrenProps {
children: JSX.Element;
}
const index = ({ children }: childrenProps) => {
return (
<>
<DesignForm />
{children}
</>
);
};
const handleTabChange = useCallback(

<pre class="lang-py prettyprint-override"><code>print(type(data) == type(ind) == list) # data and ind are lists
# OUT: True
print(len(data) == len(ind) == 134464) # data and ind have a size of 134,464
# OUT: True
print(np.alltrue([type(subarray) == np.ndarray for subarray in data])) # data (and ind) contains ndarray
# OUT: True
print(np.alltrue([len(data[i]) == len(ind[i]) for i in range(len(data))])) # each ndarray of data have the same length than the corresponding ndarray of ind
# OUT: True
print(min([len(data[i]) for i in range(len(data))]) >= 1) # each subarray of data (and of ind) has at least a length of 1
# OUT: True
print(np.alltrue([subarray.dtype == np.float64 for subarray in data])) # each subarray of data (and of ind) contains floats
# OUT: True
</code></pre>
<h2>Code</h2>
<p>Here is how I create the matrix (using <code>csr_matrix</code> from <code>scipy.sparse</code>):</p>
<pre class="lang-py prettyprint-override"><code>indptr = np.empty(nbr_of_rows + 1) # nbr_of_rows = 134,464 = len(data)
indptr[0] = 0
for i in range(1, len(indptr)):
indptr[i] = indptr[i-1] + len(data[i-1])
data = np.concatenate(data) # now I have type(data) = np.darray, data.dtype = np.float64 and len(data) = 2,821,574
ind = np.concatenante(ind) # same than above
X = csr_matrix((data, ind, indptr), shape=(nbr_of_rows, nbr_of_columns)) # nbr_of_columns = 3,991 = max(ind) + 1 (since min(ind) = 0)
print(f"The matrix has a shape of {X.shape} and a sparsity of {(1 - (X.nnz / (X.shape[0] * X.shape[1]))): .2%}.")
# OUT: The matrix has a shape of (134464, 3991) and a sparsity of 99.47%.
</code></pre>
<p>So far so good (at least I think so). But now, even though I manage to retrieve the column indices, I can’t successfully retrieve the values:</p>
<pre class="lang-py prettyprint-override"><code>print(np.alltrue(ind == X.nonzero()[1])) # Retrieving the columns indices
# OUT: True
print(np.alltrue(data == X[X.nonzero()])) # Trying to retrieve the values
# OUT: False
print(np.alltrue(np.sort(data) == np.sort(X[X.nonzero()]))) # Seeing if the values are at least the same
# OUT: False
print(np.sum(data) == np.sum(X[X.nonzero()])) # Seeing if the values add up to the same total
# OUT: False
</code></pre>
<p>When I look deeper, I find that I get <em>almost</em> all the values (only a small amount of mistakes):</p>
<pre class="lang-py prettyprint-override"><code>print(len(data) == len(X[X.nonzero()].tolist()[0]))
# OUT: True
print(len(np.argwhere((data != X[X.nonzero()]))))
# OUT: 2184
</code></pre>
<p>So I get "only" 2,184 wrong values out of 2,821,574 total values.</p>
<p>Can someone please help me in getting all the correct values from my CSR matrix?</p>
<h2>EDIT</h2>
<p>I know now thanks to @hpaulj that I can use the class attributes <code>X.indices</code> and <code>X.data</code> to retrieve the CSR format index array and the CSR format data array of the matrix. However, I still would like to know why, in my case, I don't have <code>np.altrue(X[X.nonzero()] == X.data)</code>.</p>

<p>This is my first time posting a coding question on any website, so apologies if i dont do a great job. Constructive feedback is very welcome. I am working on the tideman problem in cs50, if that is meaningful to anyone.</p>
<p>I cant figure out a way to break out of the inner nested loop but continue the outer loop. As in, if is_cycle is true, the lines:</p>
<pre><code>locked[pairs[i].winner][pairs[i].loser] = true;
num_locked++;
</code></pre>
<p>need to be skipped for that current iteration of the outer loop.</p>
<p>Thank you so much.</p>
<pre><code>// Lock pairs into the candidate graph in order, without creating cycles
void lock_pairs(void)
{
int num_locked = 0;
//loop through pairs
//has loser won before?
//if no, lock the pair
//if yes, call is_cycle on pair. if its not a cycle lock the pair
for (int i = 0; i < pair_count; i++)
{
//has the loser won before?
for (int j = 0; j < i; j++)
{
if (pairs[i].loser == pairs[j].winner)
{
//if the loser has won before and it creates a cycle, break the inner loop, continue outer
if (is_cycle(pairs[i], pairs[j], num_locked))
{
break;
}
}
}
//this is incorrect this will lock the pair each time
locked[pairs[i].winner][pairs[i].loser] = true;
num_locked++;
}
return;
}
</code></pre>
<p>I have tried searching through stack overflow. Some mentioned a <code>goto</code> function but most people said that is bad programming. someone else mentioned creating a separate function and using <code>return</code> statements but i need that outer loop to continue, not stop. And one other answer suggested using <code>flags</code>, which after more searching i still dont get how that could help.</p>

<p>I was hoping you could help me with a task in SAS. I have a data set (2 by 2 of numbers) and I would like to extract each entry and store them individually as a macro variable for later use. I am not very familiar with macros so I am not sure if this is possible.</p>
<p>Many thanks for any advice!</p>

<p>I'm trying to make a single object larger than 2GB using new operator.
But if the size of the object is larger than 0x7fffffff, The size of memory to be allocated become strange.
I think it is done by compiler because the assembly code itself use strange size of memory allocation.</p>
<p>I'm using Visual Stuio 2015 and configuration is Release, x64.</p>
<p>Is it bug of VS2015? otherwise, I want to know why the limitation exists.</p>
<p>The example code is as below with assembly code.</p>
<pre><code>struct chunk1MB
{
char data[1024 * 1024];
};
class chunk1
{
chunk1MB data1[1024];
chunk1MB data2[1023];
char data[1024 * 1024 - 1];
};
class chunk2
{
chunk1MB data1[1024];
chunk1MB data2[1024];
};
auto* ptr1 = new chunk1;
00007FF668AF1044 mov ecx,7FFFFFFFh
00007FF668AF1049 call operator new (07FF668AF13E4h)
auto* ptr2 = new chunk2;
00007FF668AF104E mov rcx,0FFFFFFFF80000000h // must be 080000000h
00007FF668AF1055 mov rsi,rax

<p>I have some Fact Revenue, I am trying to group by Conca, and display the values only if negative…</p>
<p>For doing it I have this calculated column:</p>
<pre><code>=
VAR name1 = Revenue[Conca]
VAR name2=
CALCULATE (
SUM ( Revenue[CostOfQuality] ),
FILTER ( Revenue, Revenue[Conca] = name1 )
)
RETURN
if (name2>0, 0, Revenue[CostOfQuality])
</code></pre>
<p>It works:</p>
<p><a href="https://i.stack.imgur.com/pEuUl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pEuUl.png" alt="enter image description here" /></a></p>
<p>(highest value is 0 as expected):</p>
<p>Now...</p>
<p>If I drag <strong>fiscal year</strong> it stops working:
<a href="https://i.stack.imgur.com/l8sIz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/l8sIz.png" alt="enter image description here" /></a></p>
<p>Why is it that I see numbers higher than 0?? (I want it to still work even if I bring other filters...)</p>

<p>I want to create a new view in SQL Server 2008 R2.
Given is a col called "ADRESS", based on which I want to create a col called "CompanyID".
I want to add a suffix, which counts +1 for each row in a group of adresses, ideally starting from ".002".
The output should look like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ADRESS</th>
<th>CompanyID</th>
</tr>
</thead>
<tbody>
<tr>
<td>100000</td>
<td>100000.002</td>
</tr>
<tr>
<td>100000</td>
<td>100000.003</td>
</tr>
<tr>
<td>100000</td>
<td>100000.004</td>
</tr>
<tr>
<td>200000</td>
<td>100000.002</td>
</tr>
<tr>
<td>200000</td>
<td>100000.003</td>
</tr>
<tr>
<td>300000</td>
<td>100000.002</td>
</tr>
</tbody>
</table>
</div>
<p>My idea was to declare a count variable:</p>
<pre><code>DECLARE @count AS
SET @count = '002'
</code></pre>
<p>And then use a while loop:</p>
<pre><code>WHILE ()
BEGIN
SELECT ADRESS + '.' + @count AS CompanyID
SET @count = @count +1
END
</code></pre>
<p>Problem is, I don't have a idea what to loop through and also, which data type allows 3 digits without removing the first two zeros. I'm new to SQL so i would appreciate a short explanation.</p>

<p>I am trying something like this:
<a href="https://stackoverflow.com/questions/47340518/list-append-in-pandas-cell">List append in pandas cell</a></p>
<p>But the problem is the post is old and everything is deprecated and should not be used anymore.</p>
<pre><code>d = {'col1': ['TEST', 'TEST'], 'col2': [[1, 2], [1, 2]], 'col3': [35, 89]}
df = pd.DataFrame(data=d)
</code></pre>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>col1</th>
<th>col2</th>
<th>col3</th>
</tr>
</thead>
<tbody>
<tr>
<td>TEST</td>
<td>[1, 2, 3]</td>
<td>35</td>
</tr>
<tr>
<td>TEST</td>
<td>[1, 2, 3]</td>
<td>89</td>
</tr>
</tbody>
</table>
</div>
<p>My Dataframe looks like this, were there is the col2 is the one I am interested in. I need to add [0,0] to the lists in col2 for every row in the DataFrame. My real DataFrame is of dynamic shape so I cant just set every cell on its own.</p>
<p>End result should look like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>col1</th>
<th>col2</th>
<th>col3</th>
</tr>
</thead>
<tbody>
<tr>
<td>TEST</td>
<td>[1, 2, 3, 0, 0]</td>
<td>35</td>
</tr>
<tr>
<td>TEST</td>
<td>[1, 2, 3, 0, 0]</td>
<td>89</td>
</tr>
</tbody>
</table>
</div>
<p>I fooled around with <code>df.apply</code> and <code>df.assign</code> but I can't seem to get it to work.
I tried:</p>
<pre><code>df['col2'] += [0, 0]
df = df.col2.apply(lambda x: x.append([0,0]))
Which returns a Series that looks nothing like i need it
df = df.assign(new_column = lambda x: x + list([0, 0))
</code></pre>

<p>Let it be the following python pandas dataframe.</p>
<pre><code>| date | other_columns |...
| ------------- | -------------- |...
| 2022-02-06 | row |...
| 2022-02-07 | row |...
| 2022-02-08 | row |...
| 2022-02-15 | row |...
| 2022-02-24 | row |...
| 2022-02-28 | row |...
</code></pre>
<p>I want to add the week corresponding to each date as an additional <code>week</code> column. It is simply grouping the days in 7-day intervals to assign each number. I don't want the functionality of datetime.week, I want the value to be relative to the month.</p>
<pre><code>| date | other_columns |...| week |
| ------------- | -------------- |...| -------- |
| 2022-02-06 | row |...| 1 week |
| 2022-02-07 | row |...| 1 week |
| 2022-02-08 | row |...| 2 week |
| 2022-02-15 | row |...| 3 week |
| 2022-02-24 | row |...| 4 week |
| 2022-02-28 | row |...| 5 week |
</code></pre>
<p>(1-7) correspond to the first week, (8-14) to the second, (15-21) to the third one, (21-28) fourth, (29-31) fifth. Only the day number really matters, not the month.</p>

<p>This is in reference to my previous <a href="https://stackoverflow.com/q/74589537/6744609">question </a>related to extracting data from .asc file and separating them while having multiple delimiters.</p>
<p>I want to perform mathematical operations on the float elements of the list of lists generated from the above question. The separation of individual data from the string has been achieved however, since the list of lists has also generated individual elements in form of strings i am unable to perform mathematical operations on them.</p>
<p>I would like to be able to access each element in the list of lists, convert them to float type and then perform mathematical operations on them.</p>
<p><a href="https://i.stack.imgur.com/m3jCi.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/m3jCi.png" alt="enter image description here" /></a></p>
<p>Here is my code where in the .asc file strings have been separated into individual elements and stored as list of lists.</p>
<p>This is the image of a specific set of datas i got from the bigger list of lists.</p>
<p><a href="https://i.stack.imgur.com/mlxwP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mlxwP.png" alt="enter image description here" /></a></p>
<p>I access the specific set of data from the lists and then when i try to convert them to float, i get this error
<strong>ValueError: could not convert string to float: '.'</strong></p>
<p>This is the code i have been working with</p>
<pre><code>import numpy as np
import pandas as pd
import re
Output_list = []
Final = []
count = 0
with open(r"myfile.asc","r") as file_in:
for line in map(str.strip, file_in):
if "LoggingString :=" in line:
first_quote = line.index('"') # returns the column number where '"' first appears in the
# whole string
last_quote = line.index('"', first_quote + 1) #returns the column value where " appears last
#in the # whole string ( end of line )
Output_list.append(
line[:first_quote].split(maxsplit=1)
+ line[first_quote + 1: last_quote].split(","),
)
Final.append(Output_list[count][8:25])
Data = list(map(float, Output_list[count][8])) #converting column 8th element of every lists
#in Output_list to float
count += 1
df = pd.DataFrame(Output_list)
df.to_csv("Triall_2.csv", sep=';')
df_1 = pd.DataFrame(Final)
df_1.to_csv("Test.csv", sep=";")
</code></pre>
<p>I alternatively tried using np.array(Final).astype(float).tolist() method as well but it didn't change the strings to float as i wanted.</p>

</code></pre>
<p>But I don't want every change from the entire form, just from some of the controls, but I can't do this approach:</p>
<blockquote>
<p>this.profileForm.controls['firstName'].valueChanges...</p>
</blockquote>
<p>because my form is dynamic.
so I tried to create an array in my dynamic method, something like that will return this.</p>
<pre><code>controlsTrigger = ['firstname', 'age'];
</code></pre>
<p>note that the last name it's should not trigger the console.log.</p>
<p>so I saw the merge operator from rxjs</p>
<pre><code>merge(
this.form.get("firstname").valueChanges,
this.form.get("age").valueChanges,
).subscribe(() => console.log('changed'));
</code></pre>
<p>But I want to use it with dynamics controls.</p>

<p>i want to ask how do i navigate tabs inside the DefaultTab, i have DefaultTabController Page that i name it OrderList inside OrderList i have 3 different tab which Progress,Complete and Cancel when i click button i want to navigate it to OrderList that show Cancel page. Below is my code. If i directly navigate to OrderList, it will show the first page which is progress, i wanted it to navigate to the 3rd page which is the cancel page.</p>
<pre><code>class _OrderListState extends State<OrderList> {
@override
Widget build(BuildContext context) {
return DefaultTabController(
length: 3,
child: Container(
decoration: BoxDecoration(
color: Colors.teal[300],
),
child: Scaffold(
bottomNavigationBar: BottomNavigationBarForAppClient(indexNum: 1),
backgroundColor: Colors.transparent,
appBar: AppBar(
title: const Text('Order List'),
centerTitle: true,
flexibleSpace: Container(
decoration: BoxDecoration(
color: Colors.teal[300],
),
),
),
body: Column(
children: [
TabBar(tabs: [
Tab(
text: 'In Progress',
),
Tab(
text: 'Completed',
),
Tab(
text: 'Cancelled',
),
]),
Expanded(
child: TabBarView(children: [
ProgressClient(),
CompletedClient(),
CancelledClient(),
]),
)
],
),
),
),
);
}
}
</code></pre>
<p>this is the other page code. As you can see here i navigate it to OrderList() and the default tab inside OrderList ProgressClient , i want it to go to the CancelledClient tab</p>
<pre><code>IconButton(
onPressed: () {
Navigator.pushReplacement(context,
MaterialPageRoute(builder: (context) => OrderList()));
},
icon: Icon(Icons.arrow_back, size: 40, color: Colors.white)),
</code></pre>

<p>I have the next question about webtable handling over Robot Framework with selenium:</p>
<p>the webpage has a table with 3 columns, but the rows are variable based on the months of a year, I already use the 'Table Column Should Contain' to confirm the existence of a row with the text of a month (i.e. 'monthA'), but now I need to work with the adjacent cells based on that row</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Column A</th>
<th>Column B</th>
<th>Column C</th>
</tr>
</thead>
<tbody>
<tr>
<td>monthA</td>
<td>orderA</td>
<td>link A</td>
</tr>
<tr>
<td>monthB</td>
<td>orderB</td>
<td>link B</td>
</tr>
</tbody>
</table>
</div>
<p>so far I'm trying to get a list of the available rows with</p>
<pre><code>${rows}= Get Element Count //*[@id="root"]/div[2]/div/div[2]/div[9]/div/table/tbody/tr
</code></pre>
<p>which gives me back the number of rows, but when I try to use it in a FOR cycle to get the names and the corresponding row, the index doesn't work, and looks like it doesn't recognize the value 0 of the index, the operation I try to do in the cycle is</p>
<pre><code>${value} Get Text (//*[@id="root"]/div[2]/div/div[2]/div[9]/div/table/tbody/tr)[${i}]
</code></pre>
<p><a href="https://i.stack.imgur.com/WjTlw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WjTlw.png" alt="enter image description here" /></a></p>
<p>for now I'm stuck in that part trying to figure how to make the index work</p>

<p>If you have two Xpaths you can join them with the <code>|</code> operator to return both their results in one result set. This essentially gives back the union of the two sets of elements. The example below gives back all <code>div</code>s and all <code>span</code>s on a website:</p>
<pre><code>//div | //span
</code></pre>
<p>What I need is the difference (subsection). I need all elements in the first Xpath group that are not in the second Xpath group. So far I have seen that there is an <code>except</code> operator but that only works in Xpath2. I need an Xpath1 solution. I have seen that the <code>not</code> function might help but I was not able to make it work.</p>
<p>As an example imagine the following:</p>
<pre><code><tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
</tr>
</code></pre>
<p>In this example I would have the Xpath group <code>//tr/td</code>. I would want to <strong>exclude</strong> <code><td>1</td></code> and <code><td>4</td></code>. Although there are many ways to solve the problem I am specifically looking for a solution where I can say in an Xpath: "Here is a group of elements and exclude this group of elements from it".</p>

<p>I have a <code>df</code> as below</p>
<pre><code>df <- data.frame(col1 = c("a", "a", "b",
"b", "c", "c"),
col2 = c("x1", "x1.1", "x2", "x2.1", "x3", "x3.1"),
col3 = c(1, NA, 2, NA, 3, NA),
col4 = c(NA, 1, NA, 2, NA, 3))
df
col1 col2 col3 col4
1 a x1 1 NA
2 a x1.1 NA 1
3 b x2 2 NA
4 b x2.1 NA 2
5 c x3 3 NA
6 c x3.1 NA 3
</code></pre>
<p>I want to merge rows that have the same letter in column <code>col1</code> and filter rows in column <code>col2</code> by telling them <code>col2 %in% c(x1,x1.1) & col2 %in% c(x2,x2.1) & col3 %in% (x3,x3.1)</code>, simulatenously.</p>
<p>My desired output would be:</p>
<pre><code> col1 col2 col3 col4
1 a x1 1 1
2 b x2 2 2
3 c x3 3 3
</code></pre>
<p>One solution from my side is to call if <code>x == "x1"</code>, then <code>col4</code> will be filled by values assosicated with <code>x == "x1.1"</code></p>
<p>Any suggestions for this to <code>group_by</code> <code>col1</code>? Thank you in advance!</p>
<p><strong>Additional note</strong></p>
<p>I did draw a pic for visualization, that I think would be easier for you to imagine.</p>
<p><a href="https://i.stack.imgur.com/YSXMK.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YSXMK.jpg" alt="enter image description here" /></a></p>
<p>The values in the actual dataset are different from the example here.</p>
<p><strong>Updated solution</strong>
I found a solution with the help of akrun see here: <a href="https://stackoverflow.com/questions/69789751/use-separate-after-mutate-and-across/69789799#69789799">Use ~separate after mutate and across</a></p>
<pre><code>df |>
mutate(col2 = substring(col2, 1,2)) |>
mutate_if(is.numeric, ~replace(., is.na(.), "")) |>
group_by(col1, col2) |>
summarise(across(c(col3, col4), ~toString(.)), .groups = "drop") |>
mutate(col3 = str_remove(col3, ",")) |>
mutate(col4 = str_remove(col4, ", "))
</code></pre>
<p>I'm still open to further suggestions, if anyone has any.</p>

<p>Is there a way to have a function take in a list and then return true or false for each item in the list if they are palindromes? Below is what I have tried but I would like the console to look like this:</p>
<p>True
False
True</p>
<pre><code>x=[121,13,155551]
def palindrome_check(x):
for num_from__list in x:
if str(num_from__list) == str(num_from__list[::-1]):
return True
continue
else:
return False
print(palindrome_check(x))
</code></pre>

<p>I have the next matrix:</p>
<pre><code>structure(list(`1` = c(0, 0, NA, NA, NA, NA, 0, 0, NA, NA, NA,
1, NA, NA, NA), `2` = c(1, 0, NA, NA, NA, NA, NA, 0, NA, NA,
NA, 1, NA, NA, NA), `4` = c(NA, NA, 0, 1, 1, 0, NA, NA, 0, 1,
1, NA, 1, 0, 0), `5` = c(NA, NA, 0, 1, 1, 0, NA, NA, 1, 1, NA,
NA, 1, 0, 1), `6` = c(NA, NA, 0, 1, 1, 0, NA, NA, 1, 0, NA, NA,
1, 0, NA), `7` = c(NA, NA, NA, 1, 1, 0, NA, NA, 0, 1, NA, NA,
1, 0, NA), `8` = c(NA, NA, NA, 1, 0, 0, NA, NA, 1, 0, NA, NA,
1, 0, NA)), row.names = c(NA, 15L), class = "data.frame")
</code></pre>
<p>I want to create the following matrix based in the previous matrix, I have created the next code but it does not work.</p>
<pre><code>for(i in 1:nrow(mat)){
for(j in 1:7){
if(mat[i,j]==0){
next }else{
if(mat[i,j]==1){
mat[i,j:7]<-1
}else{
if(is.na(mat[i,j])){
mat[i,j]<-NA
}}}
}
}
</code></pre>
<p>The idea is for each row for example:</p>
<p>0,0,0,1,0,0,0</p>
<ul>
<li>if in the row there is a 1, then all the elements after this 1 should be equals 1.</li>
<li>if there is an NA then this value should be equals NA</li>
</ul>
<p>The idea is to create a matrix describing an intervention over time. I mean 1 is when the intervention is applied.</p>
<ul>
<li>If I have something like this:
0,NA,NA,1,0,NA,1
I want to get for example:
0,NA,NA,1,1,NA,1</li>
</ul>
<p>I hope you can help me with it.</p>

<p>I'm stuck on an exercise where I should do a function which makes a tuple out of 3 given numbers and returns tuple following these rules:</p>
<ul>
<li>1st element must be the smallest parameter</li>
<li>2nd element must be the biggest parameter</li>
<li>3rd element is the sum of parameters</li>
</ul>
<p>For example:</p>
<pre><code>> print(do_tuple(5, 3, -1))
# (-1, 5, 7)
</code></pre>
<p>What I have so far:</p>
<pre><code>def do_tuple(x: int, y: int, z: int):
tuple_ = (x,y,z)
summ = x + y + z
mini = min(tuple_)
maxi = max(tuple_)
if __name__ == "__main__":
print(do_tuple(5, 3, -1))
</code></pre>
<p>I know I should be able to sort and return these values according to the criteria but I can't work my head around it..</p>

<p>I have a PHP code</p>
<pre><code><?php $j = 0; foreach($v->valeur as $valeur) { ?>
<input type="checkbox"
class=" "
name="check<?php echo $v->id; ?>[]"
value="<?php echo $j; ?>"
<?php if(strpos($v->active,','.$j.',')!==false) echo ' checked'; ?>
data-labelauty="<?php echo $valeur; ?>" />
<?php echo $valeur.str_repeat('&nbsp;', 2); ?>
<?php ++$j; ?>[![enter image description here][1]][1]
<?php } ?>
</code></pre>
<p>where
<code>echo $valeur.str_repeat('&nbsp;', 2);</code> generates " Djembe ".
My problem is that I want the checkbox and the text to be on THE SAME LINE reagardless of screen width.

<p>now I'm making a user Authentication system, but I'm having trouble with javascript's process order. Here is my code.</p>
<pre><code>const isAuthenticated = async (username, password) => {
//this User.finOne is async function
User.findOne({ username: username }, function (err, foundUser) {
if (err) {
console.log(err);
}
else {
if (foundUser) {
if (foundUser.password === password) {
console.log("ID:", foundUser.id);
console.log("NAME:", foundUser.username);
return foundUser.id
}
}
else {
return 0;
}
}
});
}
app.post("/login", async function (req, res) {
const userName = req.body.username;
const password = md5(req.body.password);
let userID = await isAuthenticated(userName, password);
// userID becomes undefined
console.log("userID", userID);
if (userID === 0 || userID == undefined) {
const status = 401
const message = 'Incorrect username or password'
res.status(status).json({ status, message })
return
}
const accessToken = createToken({ id: isAuthenticated(userName, password) })
console.log("here is token", accessToken);
const responseJson = {
success: true,
username: userName,
userID: userID
}
res.cookie('JWTcookie', accessToken, { httpOnly: true })
res.status(200).json(responseJson)
</code></pre>
<p>When a user logged in with a correct password and username, this API is supposed to return cookie. This cookie itself works fine, but the problem is that " if (userID === 0 || userID == undefined)" is processed earlier than the function isAuthenticated().
When I checked the order, isAuthenticated is processed later. To prevent this, I tried using async await, so that the job stops at let userID = await isAuthenticated(userName, password);. But this didn't work.</p>
<p>If anyone point out why this programming is working in this order, I really appreciate it. Thank you.</p>

<p>This is part of a homework assignment. As part of an administration script, one of the tasks is to open an interactive Powershell prompt on a remote computer using preset credentials from the script. Opening one from the regular interactive shell works fine, however opening one from a script has proven to be difficult.</p>
<p>I have tried the following:</p>
<pre><code>$password = ConvertTo-SecureString -String "password" -AsPlainText -Force`
$credentials = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "username", $password
$session = New-PSSession -Credential $credentials -ComputerName "remote-computer"
Enter-PSSession -Session $session
</code></pre>
<p>Doing this from an interactive shell works as expected and spawns an interactive prompt on the remote machine, however doing this from a script results in a non-responsive shell as it expects further input from the script.</p>
<p>If I attempt <code>Start-Process -Wait -NoNewWindow -FilePath "powershell"</code> or tell <code>Start-Process</code> to execute Powershell via cmd.exe after entering a remote Powershell session it opens a local instance instead.</p>

<p>The <code>Series.str.find()</code> function in pandas seems to take only a single integer for the start location. I have a Series containing strings and an array of start positions, and I want to find the position of a given substring starting from the corresponding position of each element as follows:</p>
<pre><code>a = pd.Series(data=['aaba', 'ababc', 'caaauuab'])
a.str.find('b', start=[0, 1, 2]) # returns a series of NaNs
</code></pre>
<p>I can do this using list comprehension:</p>
<pre><code>[s.find('b', pos) for s, pos in zip(a.values, [0, 1, 2])]
</code></pre>
<p>Is there a function in numpy or pandas that can do this directly and faster? Also, is there one that can take an array of substrings as well?</p>

<p>I have the following df as example:</p>
<pre><code>df <- data.frame(status = c(rep("egr", 5), rep("ing", 5)),
ua = c(1, 1, 1, 1, 1, 1, 1, 1, 2, 2),
fam = c(rep("fam1", 2), rep("fam2", 7), "fam3"),
spp = c(rep("spp1", 3), rep("spp2", 3), "rep4", "rep5", rep("spp6", 2)))
</code></pre>
<p>What I'm trying to do is <code>summarise</code> the count of strings based on a <code>group_by</code> of the <code>ua</code> column and the differences between the names of <code>fam</code> and <code>spp</code> when comparing the two <code>status</code> (ing, egr).</p>
<p>In other words, for each <code>ua</code>, I want to count via <code>summarise</code> the differences between <code>ing</code> - <code>egr</code> for each other column (<code>spp</code> and <code>fam</code>). I'm having an issue specifically assigning the <code>status</code> column as the base for the differences, i.e., getting the names of <code>spp</code> and <code>fam</code> at each <code>status</code> before summarizing. A <code>setdiff</code> between <code>fam</code> or <code>spp</code> from each <code>status</code> seems enough, but I'm failing at, again, assigning the <code>status</code> before the summary.</p>
<p>EDIT:</p>
<p>Getting the different number of names in <code>ing</code> minus <code>egr</code>, an output might look like</p>
<pre><code>output <- data.frame(ua = c(1, 2),
fam = c(-1, 2),
spp = c(1, 1))
</code></pre>
<p>Example rationale:</p>
<p><code>ua</code> 1 has, considering both <code>egr</code> and <code>ing</code>, two names of <code>fam</code> (fam1 and fam2). Since fam2 is shared between <code>ing</code> and <code>egr</code>, the diff is 0. But <code>egr</code> has also <code>fam1</code>, then the difference became -1.</p>
<p>Another example: <code>ua</code> 2 has no <code>egr</code>, then the sum is simply 2 (fam2 and fam3).</p>
<p>Again: <code>ua</code> 1 has, considering both <code>ing</code> and <code>egr</code>, four <code>spp</code> (spp1, spp2, rep4, rep5). Doing the <code>ing</code> minus <code>egr</code>, it must result in 1 because <code>ing</code> has two unique names and (rep4 and rep5) and <code>egr</code> one (spp1). Thus, the diff of <code>ing</code> - <code>egr</code> is 1 since spp2 is shared</p>
<p>I hope this is understandable, it's kinda tricky to explain.</p>

<pre><code>class LoginScreen extends StatefulWidget {
final VoidCallback onClickedSignUp;
const LoginScreen({Key? key, required this.onClickedSignUp})
: super(key: key);
@override
State<LoginScreen> createState() => _LoginScreenState();
}
class _LoginScreenState extends State<LoginScreen> {
TextEditingController emailController = TextEditingController();

});
}
}
</code></pre>
<p>main.dart:</p>
<pre><code>class MainPage extends StatelessWidget {

<p>I need to programmatically delete all caches of my Xamarin.Forms application called MyXFApp, the same way as the button 'Clear Cache' of the Setting/Apps/MyXFApp/Storage page.</p>
<p>I read the Android and Xamarin.Forms official documentations, and used the methods getGetCacheDir() and GetExternalCacheDir() to retrieve the cache directories, and I delete both of them.
After deleting both directories, I expect to see the cache size to 0 byte within the Setting/Apps/MyXFApp/Storage page. But the cache size displayed in the Setting/Apps/MyXFApp/Storage page has indeed diminished, but is not strictly equal to 0 byte, and I do not understand why?</p>
<p>Is there any other directory I must delete in order to fully clear my Xamarin.Forms cache? Or is it a bug of the Setting/Apps/MyXFApp/Storage displayed cache size?</p>
<p>And otherwise, what is the correct way or difference(s) between these two methods?</p>
<p>I tried to delete directories obtained from methods getGetCacheDir() and GetExternalCacheDir().
Expected to see cache size of 0B in the Setting/Apps/MyXFApp/Storage page, but I see 20KB and not 0B.</p>

<p>I'm trying to map one key to each value in array to a new array by using JOLT.
Could someone please help give me a solution for this:</p>
<p>My JSON:</p>
<pre class="lang-json prettyprint-override"><code>[
{
"person_id": "1",
"resources": ["asd", "zxc"]
},
{
"person_id": "2",
"resources": ["ghj", "asd"]
}
]
</code></pre>
<p>And my expected JSON:</p>
<pre class="lang-json prettyprint-override"><code>[
{
"person_id": "1",
"resource": "asd"
},
{
"person_id": "1",
"resource": "zxc"
},
{
"person_id": "2",
"resource": "ghj"
},
{
"person_id": "2",
"resource": "asd"
}
]
</code></pre>
<p>I had tried this Jolt Specification</p>
<pre class="lang-json prettyprint-override"><code>[
{
"operation": "shift",
"spec": {
"*": {
"resources": {
"*": {
"@(2,person_id)": "[&].person_id",
"@": "[&].resource"
}
}
}
}
}
]
</code></pre>
<p>But no luck it always maps all values at the same index to 1 array.</p>

<p>The example code is using DryWetMidi library. The program plays a MIDI file (MIDI.Path) on button click until the file ends. The problem is there seems to be no way of stopping the playback with another button.</p>
<p>Is there anyone who has experience with the MIDI library that knows how to make a button that stops the current file playback?</p>
<pre><code>@using Melanchall.DryWetMidi.Multimedia;
@using Melanchall.DryWetMidi.Core;
<span @onclick="@(() => PlayMidi())">
<button>Play</button>
</span>
@code{
private static Playback playback;
public void PlayMidi()
{
var midiFile = MidiFile.Read(MIDI.Path);
var outputDevice = OutputDevice.GetByName("Microsoft GS Wavetable Synth");
playback = midiFile.GetPlayback(outputDevice);
playback.Start();
SpinWait.SpinUntil(() => !playback.IsRunning);
Console.WriteLine("Playback stopped or finished.");
outputDevice.Dispose();
playback.Dispose();
}
}
</code></pre>

I generate a list of dates (days of the month) in the view and display it in the form in templates along with the fields next to the type.

<p>I am making a web app with VueJS that makes axios calls to a NodeJS API that uses express. I'm currently trying to send files to my NodeJS so it can save them. However, even though my browser displays all the properties of my array of files, my NodeJS reads it as empty. I've read all the questions previously asked on this topic but I haven't made any progress whatsoever. Note that I can POST any other data just fine, all my SQL Insert requests do well, mind you they don't involve sending arrays.</p>
<p>Example of promising solution that did not work : <a href="https://stackoverflow.com/a/66541165/12498040">https://stackoverflow.com/a/66541165/12498040</a></p>
<p>Here is my client side JS, console.log() prints an array of N files object in the browser console :</p>
<pre><code> console.log(data)
await axios.post('/api/fichiers', {fichiers:data});
</code></pre>
<p>Here is my NodeJS, with console.log(element) it prints N number of "{}" in the browser console and console.log(element.name) prints N number of "undefined" in the server terminal :</p>
<pre><code>app.post('/api/fichiers', (req, res) => {
req.body.fichiers.forEach((element) => {
console.log(element.name);
});
});
</code></pre>
<p>Thank you for any help you could provide :)</p>

<p>I want to find the .txt file with the shortest name inside a folder.</p>
<pre><code>import glob
import os
inpDir = "C:/Users/ft/Desktop/Folder"
os.chdir(inpDir)
for file in glob.glob("*.txt"):
l = len(file)
</code></pre>
<p>For the moment I found the length of the str of the name, how can I return the shortest name?
Thanks</p>

<p>I have a file, foo.S, which contains ARM thumb instructions, on an Ubuntu 22.04 x86_64 machine. Is it possible to convert this into an ARM object file using <code>as</code> from <code>binutils</code> or do I need to create a cross-compiler toolchain? I tried</p>
<pre class="lang-bash prettyprint-override"><code>$ as -mthumb foo.S -o foo.o
</code></pre>
<p>However, I got</p>
<pre><code>as: unrecognized option '-mthumb'
</code></pre>
<p>even though that's one of the options listed in <code>man as</code>.</p>

<p>I want to apply pagination on my data I tried to watch lots of videos and read lots of articles but still can't solve my problem. This is my Views.</p>
<pre><code>def car(request):
all_products = None
all_category = category.get_all_category()
categoryid = request.GET.get('category')
if categoryid:
all_products = Product.get_all_products_by_id(categoryid)
else:
all_products = Product.get_all_products()
data = {}
data['products'] = all_products # all products
data['category'] = all_category # all category
all_products = Product.get_all_products()
data['product'] = all_products
]
return render(request, 'car.html', data)
</code></pre>
<p>as you can see I made some changes in above code but its make no diffrence</p>
<pre><code>def car(request):
all_products = None
all_category = category.get_all_category()
categoryid = request.GET.get('category')
if categoryid:
all_products = Product.get_all_products_by_id(categoryid)
else:
all_products = Product.get_all_products()
#pagination
paginator = Paginator(all_products,2) **Changes**
page_number=request.GET.get('page') **Changes**
finaldata=paginator.get_page(page_number) **Changes**
data = {'all_products':finaldata,} **Changes**
data['products'] = all_products #all products
data['category'] = all_category #all category
all_products = Product.get_all_products()
data['product'] = all_products
return render(request, 'car.html', data)
</code></pre>
<p>I want to display 4 products per page I tried to apply data limit query that work but that not a genuine approach to display data.
I read many articles and watch YouTube video. but can't find any solution. which videos and articles I watched there pagination method is totally different they use pagination with objects.all method to get all data and I used .get method to get data I think that is my problem. and second thing is that they just working with simple data to paginate but in my case it's so complicated. I tried alot please guide. I got stuck in solving a problem for 5 days now. I am convinced that I'm not a good programmer. I tried a lot but I can't succussed.</p>

<p>I am trying to handle a dictionary that has a list as a value for a key named 'notes' , so I am trying to find the maximum element from that list and reassign the value with that maximum element from the list and also change the key value to 'top_notes' as follows.</p>
<pre><code>Input = top_note({ "name": "John", "notes": [3, 5, 4] })
Output = { "name": "John", "top_note": 5 }.
</code></pre>
<p>The output that I am getting is 'None'
Below is my code.</p>
<pre><code>class Solution(object):
def top_notes(self, di):
for key, values in di.items():
if key in di == 'notes':
lt = list(values)
maximum = max(lt)
di['top_notes'] = di['notes']
del di['notes']
di[maximum] = di[values]
del di[values]
return di
if __name__ == '__main__':
p = Solution()
dt = {"name": "John", "notes": [3, 5, 4]}
print(p.top_notes(dt))

<p>I am trying to replace the value of a variable in parameters file using Replace(). This file which I am trying to edit accepts json format. But I am unable to do so. I am using this below script to do so. This only print the name of that particular field for which I am trying to replace a numeric value.</p>
<p>I tried this but it just displays the name of the variable which contains the old value I am trying to edit/replace.</p>
<pre><code>if($Value -like "*xyz*")
{
$Value -replace '$OldValue', '$NewValue'
}
else
{
Write-Host "$OldValue"
}
</code></pre>
<p>Please provide a solution so that I can replace a numeric value of a particular variable for json file.</p>

<p>I have a 1D array which is in fact a 2D matrix sampled this way:</p>
<pre><code>↓-------<------S <- start
>------->------↓
↓-------<------<
>------->------E <- end
</code></pre>
<p>For example</p>
<pre><code>B = 1 2 3 4
5 6 7 8
9 10 11 12
</code></pre>
<p>is coded as <code>A = [4, 3, 2, 1, 5, 6, 7, 8, 12, 11, 10, 9]</code>.<br />
The number of rows can be odd or even.</p>
<p>The following code works but is inefficient due to the loop (and no vectorization). <strong>How to do a more efficient Numpy "unzigzaging"?</strong></p>
<pre><code>import numpy as np
def unzigzag(z, numcols):
numrows = len(z) // numcols
a = np.zeros((numrows, numcols))
col = numcols - 1
row = 0
sign = -1
for i in range(numrows*numcols):
if col == -1:
col = 0
sign = 1
row += 1
if col == numcols:
col = numcols - 1
sign = -1
row += 1
a[row, col] = z[i]
col += sign
return a
A = [4, 3, 2, 1, 5, 6, 7, 8, 12, 11, 10, 9]
B = unzigzag(A, 4)
#[[ 1. 2. 3. 4.]
# [ 5. 6. 7. 8.]
# [ 9. 10. 11. 12.]]
</code></pre>
<p>If possible, it would be useful to have it working even if more dimensions than 1D:</p>
<ul>
<li>if A has shape <code>(12, )</code>, <code>unzigzag(A, numcols=4)</code> has shape (3, 4)</li>
<li>if A has shape <code>(12, 100)</code>, <code>unzigzag(A, numcols=4)</code> has shape (3, 4, 100)</li>
<li>if A has shape <code>(n, i, j, k, ...)</code>, <code>unzigzag(A, numcols)</code> has shape <code>(n/numcols, numcols, i, j, k, ...)</code></li>
</ul>
<hr />
<p>Edit: example for the n-dimensional case:</p>
<pre><code>import numpy as np
def unzigzag3(z, numcols):
numrows = z.shape[0] // numcols
new_shape = (numrows, numcols) + z.shape[1:]
a = np.zeros(new_shape)
col = numcols - 1
row = 0
sign = -1
for i in range(numrows*numcols):
if col == -1:
col = 0
sign = 1
row += 1
if col == numcols:
col = numcols - 1
sign = -1
row += 1
a[row, col, :] = z[i, :]
col += sign
return a
A = np.array([[4,4], [3, 3], [2, 2], [1, 1], [5, 5], [6, 6], [7, 7], [8, 8], [12, 12], [11, 11], [10, 10], [9, 9]])
print(A.shape) # (12, 2)
B = unzigzag3(A, 4)
print(B)
print(B.shape) # (3, 4, 2)
</code></pre>
