74,401,209 | <p>I've this code in the snippet. It's an intersection Observer that tracks visible headers and adds an "active" class to the corresponding anchor tag in the top nav.</p>
<p>I would like to know if it's possible for the 'li' element with class "active" to also be scrolled into view.</p>
<p>I have tried a mutationObserver but I can't seem to make it work by any means.</p>
<p>Thanks!</p>

74,401,212 | <p>I want to aggregate a <code>pandas.Series</code> with an hourly <code>DatetimeIndex</code> to monthly values - while considering the offset to midnight.</p>
<h2>Example</h2>
<p>Consider the following (uniform) timeseries that spans about 1.5 months.</p>
<pre class="lang-py prettyprint-override"><code>import pandas as pd
hours = pd.Series(1, pd.date_range('2020-02-23 06:00', freq = 'H', periods=1008))
hours
# 2020-02-23 06:00:00 1
# 2020-02-23 07:00:00 1
# ..
# 2020-04-05 04:00:00 1
# 2020-04-05 05:00:00 1
# Freq: H, Length: 1000, dtype: int64
</code></pre>
<p>I would like to sum these to months <strong>while considering, that days start at 06:00</strong> in this use-case. The result should be:</p>
<pre><code>2020-02-01 06:00:00 168
2020-03-01 06:00:00 744
2020-04-01 06:00:00 96
freq: MS, dtype: int64
</code></pre>
<p><strong>How do I do that??</strong></p>
<hr />
<h2>What I've tried and what works</h2>
<ul>
<li><p>I <em>can</em> aggregate to days while considering the offset, using the <code>offset</code> parameter:</p>
<pre class="lang-py prettyprint-override"><code>days = hours.resample('D', offset=pd.Timedelta('06:00:00')).sum()
days
# 2020-02-23 06:00:00 24
# 2020-02-24 06:00:00 24
# ..
# 2020-04-03 06:00:00 24
# 2020-04-04 06:00:00 24
# Freq: D, dtype: int64
</code></pre>
</li>
<li><p>Using the same method to aggregate to months does not work. The timestamps do not have a time component, <strong>and the values are incorrect</strong>:</p>
<pre class="lang-py prettyprint-override"><code>months = hours.resample('MS', offset=pd.Timedelta('06:00:00')).sum()
months
# 2020-02-01 162 # wrong
# 2020-03-01 744
# 2020-04-01 102 # wrong
# Freq: MS, dtype: int64
</code></pre>
</li>
<li><p>I could do the aggregation to months as a second step after aggregating to days. In that case, the values are correct, but the time component is still missing from the timestamps:</p>
<pre class="lang-py prettyprint-override"><code>days = hours.resample('D', offset=pd.Timedelta('06:00:00')).sum()
months = days.resample('MS', offset=pd.Timedelta('06:00:00')).sum()
months
# 2020-02-01 168
# 2020-03-01 744
# 2020-04-01 96
# Freq: MS, dtype: int64
</code></pre>
</li>
<li><p>My current workaround is adding the timedelta and resetting the frequency manually.</p>
<pre class="lang-py prettyprint-override"><code>months.index += pd.Timedelta('06:00:00')
months.index.freq = 'MS'
months
# 2020-02-01 06:00:00 168
# 2020-03-01 06:00:00 744
# 2020-04-01 06:00:00 96
# freq: MS, dtype: int64
</code></pre>
</li>
</ul>

74,401,221 | <p>I am wondering is it possible to do voting for classification tasks. I have seen plenty of blogs explaining how to use voting for regression purposes.As given below.</p>
<pre><code># initializing all the model objects with default parameters
model_1 = LinearRegression()
model_2 = xgb.XGBRegressor()
model_3 = RandomForestRegressor()
# training all the model on the training dataset
model_1.fit(X_train, y_target)
model_2.fit(X_train, y_target)
model_3.fit(X_train, y_target)
# predicting the output on the validation dataset
pred_1 = model_1.predict(X_test)
pred_2 = model_2.predict(X_test)
pred_3 = model_3.predict(X_test)
# final prediction after averaging on the prediction of all 3 models
pred_final = (pred_1+pred_2+pred_3)/3.0
# printing the mean squared error between real value and predicted value
print(mean_squared_error(y_test, pred_final))

74,401,226 | <p>Have a bunch of values from csv file, with column looking like this:</p>
<pre><code>shouston
cgonzalez
bbrown
hlader
kpesavento
jbloom
polson
bcharlow
bcharlow
bkalt
</code></pre>
<p>Need to find duplicates and modify them.</p>
<pre><code># Grab CSV file
$inputFile = Import-Csv -Path $filePath
$text = (Get-Culture).TextInfo
$HashSet = [System.Collections.Generic.HashSet[string]]::new([System.StringComparer]::OrdinalIgnoreCase)
foreach ($line in $inputFile) {
$name = $line.name
$line.name = $text.ToTitleCase($name)
$firstName = $line.name.split(" ")[0]
$lastName = $line.name.split(" ")[1]
$newEmail = ($firstName[0] + $lastName).toLower()
if (!$HashSet.Add($newEmail)) {
$line.email = ($firstName[0] + $lastName + $line.location_id + "@abc.com").toLower()
}
else {
$line.email = ($firstName[0] + $lastName + "@abc.com").toLower()
}
}
$inputFile | Export-Csv $fullPath
</code></pre>
<p>But its not working as I expected - find a duplicate values and modify them. In my case, the location must also be added to the first duplicate email, example bcharlow1 bcharlow2, not it's bcharlow, bcharlow2.
Can anyone help me - how I need to modify script?</p>

74,401,252 | <p>I have an array of objects like this</p>
<pre><code>const data = [{
"id": 1,
"content": {
"type": "img",
"state": "rejected"
},
"entity": {
"type": "student",
"studentID": [

"state": "approved"
},
"entity": {
"type": "student",
"studentID": [

]
},
"status": "approved"
}
]
</code></pre>
<p>As you can see, we have 2 objects of student id 44 (one with status rejected and one with approved) and one of student id 45.
I have another array of object with student info like this</p>
<pre><code>const students = [{
student_id: 44,
fname: 'student 1',
lname: '.',
school: 'XYZ',
},
{
student_id: 45,
fname: 'student 2',
lname: '.',
school: 'ABC',
}
]
</code></pre>
<p>Now, i want to create a new array of object with both of them mapped, but each object in data mapped with their corresponding student (relation between <code>entity.studentID[0]</code> in <code>data</code> with <code>student_id</code> in <code>students</code>, so that the resultant array of object is</p>
<pre><code>[{
student_id: 44,
fname: 'student 1',
lname: '.',
school: 'XYZ',
item: {
id: 1,
status: "rejected"
},
},
{
student_id: 45,
fname: 'student 2',
lname: '.',
school: 'ABC',
item: {
id: 2,
status: "approved"
},
},
{
student_id: 44,
fname: 'student 1',
lname: '.',
school: 'XYZ',
item: {
id: 3,
status: "approved"
},
},
]
</code></pre>
<p>What i did was i ran a loop on <code>students</code> and tried using <code>map</code> but that returns me an array of objects that qualify the condition instead of the objects themselves.</p>
<pre><code>let arr = []
for (let student of students) {
let obj = { ...student
};
obj["item"] = data.map((p) => {
if (p.entity.studentId[0] === student.student_id) {
return {
id: p.id,
status: p.status,
};
}
});
arr.push(obj);
}
</code></pre>
<p>Where am i going wrong and what should i do instead?</p>

74,401,317 | <p>I have a task and I will try to explain it clearly. There is a file with [0; 1000] lines. Each line contains 6 columns.</p>
<p>The first two columns contain <em>string</em> with [1; 20] characters. Characters could be <em>letters, numbers, and whitespaces</em>.</p>
<p>3-5 columns contain integers in the range <em>[-100; 100]</em>.
6th column contain real numbers in range <em>[-9.99; 9.99]</em> with only two digits after decimal point.</p>
<p>Each section I separated by a semicolon ';'.</p>
<p><strong>FILE EXAMPLE:</strong></p>
<pre><code>helloA;lB;lC;lD;lE;lF
A11;bas morning;0;0;5;1.15
B12; Hello WoRlD;-100;11;78;1.33
B11;table;10;0;55;-2.44
C1;OakWood;0;8;17;3.77
</code></pre>
<p><strong>TASK:</strong> count how many lines in the first two sections contain the letters 'B' and 'C'. And print that integer number in the other file.</p>
<p>I did almost all the task, except one thing. I don't know how to print the decimal number in the file. I store this number in memory as <em>hexadecimal</em>. I need to convert that number to <em>decimal</em> and print it into the other file.</p>
<p>I am struggling because there could be 1 good line, but it also could be 1000 good lines. So I need to print 1 character (if the number of good lines is between [0; 9]), but it could be 900 good lines, so then the program has to print 3 characters.</p>

74,401,325 | <p>if I may, could you please help me get this sorted out? I created a circle using HTML and CSS, and inside the circle, I added text. I have other texts that need to be placed on the right side of the circle. Right now, the texts are on the right side but they are like right justified. There's too much gap. I was hoping the texts would be floating to the right side of the circle.</p>

74,401,366 | <p>I want to select columns from a dataframe,</p>
<p>however, I want to get the names and aliases from a config file and keep it variable.
The config.json file give me a dict like</p>
<pre><code>conf
"data":
{
"a":"a",
"b":"great",
"c":"example"
}
</code></pre>
<p>Now, I can select my columns like this:</p>
<pre><code>from pyspark import functions as F
df= df.select
(
F.col("a").alias("a"),
F.col("b").alias("great"),
F.col("c").alias("example)
)
</code></pre>
<p>But I would rather do it in a loop.
like</p>
<pre><code> For all data.items(), do df=df.select(F.col(item[0]).alias(item[1]))
</code></pre>
<p>But I cannot wrap my head around it(maybe I should go to bed earlier)
Thanks</p>

74,401,380 | <p>I am sending an HTTP request using XMLHttpRequest (<a href="https://developer.mozilla.org/es/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest" rel="nofollow noreferrer">https://developer.mozilla.org/es/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest</a>).</p>
<p>The code is as follows:</p>
<pre><code>var xhr = new XMLHttpRequest();
xhr.addEventListener("readystatechange", function() {
if(this.readyState === 4) {
if(this.responseText.length > 0) {
console.log(typeof this.responseText); //"string"

<p>The response of the HTTP request, this.responseText will always be a string. But it can come in two forms:</p>
<p>1: <code>"{"prop": "value", "prop": "value"}"</code></p>
<p>2: <code>"akduchkqlpouelqw"</code></p>
<p>Currently I get the string converted to an object by JSON.parse(); but there is a possibility that this.responseText is a string like case number 2 above.</p>
<p>I would like to have the possibility that if this.responseText is option two, it would go into <code>(typeof objToken === 'string')</code>.</p>
<p>I have tried this manually by giving a value to <code>var textToken === 'akduchkqlpouelqw'</code>. In that case, if I change <code>(typeof objToken === 'string')</code> to <code>(typeof textToken === 'string')</code>, it's work.</p>
<p>But I have not been able to do it dynamically.</p>

74,401,389 | <p>I'm finally trying to learn templates and I created a template function that will return an <code>std::vector</code> with a generic type.</p>
<p>When compiling I get an error:</p>
<blockquote>
<p>error: no matching function for call to
‘std::vector::push_back(std::string&)’</p>
</blockquote>
<p>Is there a way to support <code>std::string</code> or a comparable type in the template vector in addition to the primitive types?</p>
<p>Here is a 'Minimal, Reproducible Example' that doesn't compile due to this error (this is obviously not my code, it just illustrates the error):</p>
<pre><code>#include <iostream>
#include <vector>
enum types{
TINT = 0,
TDOUBLE = 1,
TSTRING = 2,
};
class TestClass{
public:
template<typename T> std::vector<T> getData(types type)
{
std::vector<T> entries;
int i_value;
double d_value;
std::string st_value;
switch (type)
{
case types::TINT:
i_value = 1;
entries.push_back(i_value);
break;
case types::TDOUBLE:
d_value = 0.1;
entries.push_back(d_value);
break;
case types::TSTRING:
st_value = "foo";
entries.push_back(st_value); //Pushing an std::string causes a compile error
break;
default:
break;
}
return entries;
}
};
int main()
{
TestClass bar;
std::vector<int> test = bar.getData<int>(types::TINT);
return 0;
}
</code></pre>
<p>Commenting the line <code>entries.push_back(st_value);</code> makes everything compile again.</p>

<p>So if I pick two different keys like:</p>
<pre><code>'chocolate':'Chocolate notes coffee: Coffee Bros Decaf, Purity Coffee Flow, Out Of The Grey Costa Rica La Minita, Lifeboost Coffee Organic Dark Roast, Coffee Bros Dark Roast, Death Wish Coffee, Kicking Horse Coffee Grizzly Claw.',
'medium':'Volcanica Coffee Kenya AA, Coffee Bros Decaf, Purity Coffee Flow, Out Of The Grey Costa Rica La Minita, Kicking Horse Three Sisters.',
</code></pre>
<p>They have a common coffee name like:</p>
<blockquote>
<p>Purity Coffee Flow, Out Of The Grey Costa Rica La Minita</p>
</blockquote>
<p>So if I insert the keys for it like: <strong>chocolate</strong>, <strong>medium</strong>.</p>
<p>The program need to print only those two duplicates:</p>
<blockquote>
<p>Purity Coffee Flow, Out Of The Grey Costa Rica La Minita</p>
</blockquote>
<p>It's possible to print just those 2 words in console which are duplicates in there?</p>
<p>The only thing that I manage to work is to print the duplicates values if values are completly the same, but that's not my use case.</p>

74,401,454 | <p>I am practicing with C # Lists in Unity and I have encountered a problem.
My test script, instantiates 5 prefabs which are added in a gameobject list. I then wrote a code that generates a random int and from that number moves the prefab instantiated with that index (indexof). Everything works correctly, but the method that moves and deletes the prefab is repeated for all the gameobjects in the scene with an index higher than the one chosen. I enclose the two scripts to better explain the problem. (I would need the unlist method to be done only once.</p>
<p>how can i solve this problem and remove one item from the list at a time? (one each time the button is pressed, not all as it is now. Thanks)</p>
<p>script:</p>
<ul>
<li>NpcController: Added in each instantiated prefab</li>
<li>ListCOntroller: added in the scene.</li>
</ul>
<hr />
<pre><code> public class ListCOntroller : MonoBehaviour
{
public GameObject cubePrefab;
private GameObject cubeInstance;
public static List<GameObject> cubeList = new List<GameObject> ();
public TextMeshProUGUI checkText;
public static event Action chooseNpc;
public static int randNpcValue;
int rand;
private void Start()
{
for(int i =0; i < 5; i++)
{
cubeInstance = Instantiate(cubePrefab, new Vector3(i, -2, 0), Quaternion.identity);
cubeList.Add(cubeInstance);
}
}
public void CheckListText()
{
checkText.text = "Npc in list: " + cubeList.Count.ToString();
}
public static void SelectRandomCube()
{
randNpcValue = Random.Range(0, cubeList.Count);
chooseNpc?.Invoke();
}
}
</code></pre>
<hr />
<p>public class NpcController : MonoBehaviour
{</p>
<pre><code>void Start()
{
ListCOntroller.chooseNpc += NpcEvent;
}
private void NpcEvent()
{
if (ListCOntroller.cubeList.IndexOf(gameObject) == ListCOntroller.randNpcValue)
{
transform.localPosition = new Vector3(transform.position.x, 2, 0);
DeleteFromList();
}
}
private void DeleteFromList()
{
ListCOntroller.cubeList.RemoveAt(ListCOntroller.randNpcValue);
Debug.Log($"Delete from list: {ListCOntroller.randNpcValue}");
}

74,401,499 | <p>I am writing a driver model using C++ and Python to compare the performance.
The simulation gives data like width, position, speed, etc. and the driver model does some calculations to decide if it needs to brake or not.
Both models have the same variables and calculations, but after looping over 500 times first divergence surface and in the end, result in different brake responses. I am aware that floating point error is a thing, but shouldn't it be the same for both languages?
I checked C++ and Python if they have IEEE 754 and it seems to be the case. I will attach my check at the end of the question.</p>
<p>Is there something I don't know about float calculations or I do sth wrong in my codes?</p>
<p>What did I expect: That I get the same response for both driver models.</p>

<p>EDIT: Minimal Working examples (Removed the logging but left the parsing, since I believe it is good to have he actual data from the sim)</p>
<p>It has been some time, since I tried different ways to work around this issue. Sadly, everything I tried didn't work out, so here I am finally following up with the minimal working example. There is one .csv file with the data from the simulation and a minimal version for both, C++ and Python. To clarify, I have the driver model and would like them to break at the same time. For this, vp, vTheta and vThetaDot should be roughly the same. As it is now, vp is 0.0825 in Pyhton and 0.00054 in C++...</p>
<p>Python minimal working example</p>
<pre><code>from numpy import nan, arctan2

self.vTheta: float = nan
self.vThetaDot: float = nan
self.prevDistEgoToTarget: float = nan
self.timestep: float = 0.01
self.vpp: float = nan
def runAccumulator(self, data):
#storing values from previous run
prevVTheta = self.vTheta

# calculate positional data
targetPosRear = float(data["targetPosX"]) - length/2.0 # adapt arctan2 input
egoPosFront = float(data["egoPosX"]) + length/2.0
distEgotoTarget = targetPosRear - egoPosFront
# optical size target vehicle and looming
self.vTheta = 2.0*arctan2(width,2.0*self.prevDistEgoToTarget)
self.vThetaDot = (self.vTheta - prevVTheta)/self.timestep
self.vp = self.vThetaDot/self.vTheta

74,401,503 | <p>I want to make some basic math stuff like Sum in Diagrams.net (old Draw.io).Is it possible ?</p>
<p>Exemple : I create a new parameter on a shape, like "Elec : T16" and make several copy on this shape. Is it possible to have a Text which can give me the total of the shape with this parameter ?</p>
<p>Best Regards.</p>
<p>I search a lot in the Diagrams.net blog but anything relevent.</p>

74,401,598 | <p>I'd like to add a new column to my Options list. The new column would calculate the difference between the last stock price at close and the Option Strike in percentage.</p>
<p>Here's my code</p>
<p>#Getting Options data and creating an list containing only Puts</p>
<pre><code>library(quantmod)
Symbols<-c ("AA","AAL","AAOI","ABBV","ABC","ABNB")
Options.20221111 <- lapply(Symbols, getOptionChain)

</code></pre>
<p>#Getting Stock data</p>
<pre><code>start_date=as.Date("2022-06-01")
getSymbols(Symbols,from=start_date)
</code></pre>
<p>Next, I'd like to add a new column to only_puts_list called "%Strike-StockPrice", that would calculate the difference between the last Stock(Close.price) price calculated in getSymbols minus the Strike values (all of them in the only_put_list) in percentage.</p>
<p>For example, if the last Close price of a stock is 100 and a Strike price is 90, there is a 10% difference. The new column would make the calculation for all Strikes of the only_put_list.</p>
<p>Thanks for any input.</p>

74,401,667 | <p>I'm in the process of learning WPF and the MVVM design pattern. Currently the code in my ViewModel for a delete customer command looks like this:</p>
<pre><code> public class vmCustomers : INotifyPropertyChanged
{
...
private ICommand _commandDeleteCustomer = null;
...
public ICommand CommandDeleteCustomer
{
get
{
if (_commandDeleteCustomer == null)
_commandDeleteCustomer = new RelayCommand<object>(DeleteCustomerAction, DeleteCustomerPredicate);
return _commandDeleteCustomer;
}
}
private void DeleteCustomerAction(object o)
{
...stuff...
}
private bool DeleteCustomerPredicate(object o)
{
...stuff...
return true;
}
}
</code></pre>
<p>I'd like to slim down the declaration of the ICommand to something like this so that I can reduce the coding overhead for each command:</p>
<pre><code>public readonly ICommand CommandDeleteCustomer = new RelayCommand((obj) => DeleteCustomerAction(obj), (obj) => DeleteCustomerPredicate(obj));
</code></pre>
<p>But I get this error:</p>
<p><code>A field initializer cannot reference the non-static field, method, or property vmCustomers.DeleteCustomerAction(object)</code></p>
<p>Is there a way I can declare the ICommand in a single line of code so that I can simply focus on business-related code rather than repeated infrastructure code.</p>

74,401,764 | <p>I want to collect the associated keys of List of maximum numbers from Map<String,Integer> in Java 8+</p>
<p>For example:</p>
<pre class="lang-java prettyprint-override"><code>final Map<String, Integer> map = new HashMap<>();
map.put("first", 50);
map.put("second", 10);
map.put("third", 50);
</code></pre>
<p>here I want to return the List of keys associated with maximum values.</p>
<p>For the above example, expected output is [first,third]. Because these 2 keys having the same max value.</p>
<p>I tried with below approach, but able to get single max key only.</p>
<pre class="lang-java prettyprint-override"><code>final String maxKey = map.entrySet()
.stream()
.max(Map.Entry.comparingByValue())
.map(Map.Entry::getKey)
.orElse(null);
final List<String> keysInDescending = map.entrySet()
.stream()
.sorted(Map.Entry.<String,Integer>comparingByValue().reversed())
.map(Map.Entry::getKey)
.collect(Collectors.toList());
System.out.println(maxKey); // third
System.out.println(keysInDescending); //[third, first, second]
</code></pre>
<p>But my expected output is [first, third]. How can we achieve it in Java 8+ versions?</p>

74,401,791 | <p>I'm trying to run a datediff. I essentially want to say the number of days between 1st November 2022 and 1st November 2022 is ONE day.</p>
<p>When I attempt this, <code>$number_of_days</code> returned is 0. Can someone explain why this is and how to resolve?</p>
<pre><code>$end = "2022-11-01";
$start = "2022-11-01";
$datediff = ($end - $start) + 1; // tried to fix
echo $datediff;

74,401,793 | <p>I'm trying to find a part in multiple strings, that all strings share in common. For example:</p>
<pre class="lang-js prettyprint-override"><code>const string1 = '.bold[_ngcontent="_kjhafh-asda-qw"] {background:black;}';
const string2 = '[_ngcontent="_kjhafh-asda-qw"] {background-color:hotpink;}';
const string3 = 'div > p > span[_ngcontent="_kjhafh-asda-qw"] {background:hotpink;}'
</code></pre>
<p><strong>I don't know in advance what exactly the string is that I'm looking for</strong>, so I have to loop over the strings and find out. In the example above, the pattern would be <code>[_ngcontent="_kjhafh-asda-qw"]</code>.</p>
<p>Is this even possible? Also, it would have to understand that maybe no such pattern exists. And are there methods for that or do I need to implement such an algorithm myself?</p>
<p>EDIT (context): We are building a validator, that checks a micro-frontend for global CSS rules (not prefixed and outside a shadow-dom), by loading it in isolation in a headless browser (within a jenkins pipeline) and validate, that it should not break any other stuff by global rules, that might be outside the context of the micro-frontend, on the same page. Using a headless browser, we can make use of the <code>document.styleSheets</code> property and not miss any styles that are being loaded. This will find <code><style></code> tags and its contents, aswell as content of external stylesheets.</p>

74,401,802 | <p>My requirement is I have a large dataframe with millions of rows. I encoded all strings to numeric values in order to use <code>numpys</code> vectorization to increase processing speed.</p>
<p>So I was looking at a way to quickly check if a number exists in another list column. Previously, I was using list comprehension with string values, but with after converting to <code>np.arrays</code> was looking at similar function.</p>
<p>I stumbled across this link: <a href="https://stackoverflow.com/questions/67158284/check-if-values-of-a-column-are-in-values-of-another-numpy-array-column-in-panda">check if values of a column are in values of another numpy array column in pandas</a></p>
<p>In order to the <code>numpy.isin</code>, I tried running below code:</p>
<pre><code>dt = pd.DataFrame({'id' : ['a', 'a', 'a', 'b', 'b'],
'col_a': [1,2,5,1,2],
'col_b': [2,2,[2,5,4],4,[1,5,6,3,2]]})
dt
id col_a col_b
0 a 1 2
1 a 2 2
2 a 5 [2, 5, 4]
3 b 1 4
4 b 2 [1, 5, 6, 3, 2]
</code></pre>
<p>When I enter:</p>
<pre><code>np.isin(dt['col_a'], dt['col_b'])
</code></pre>
<p>The output is:</p>
<pre><code>array([False, True, False, False, True])
</code></pre>
<p>Which is incorrect as the 3rd row has 5 in both columns <code>col_a</code> and <code>col_b</code>.</p>
<p>Where as if I change the value to 4 as below:</p>
<pre><code>dt = pd.DataFrame({'id' : ['a', 'a', 'a', 'b', 'b'],
'col_a': [1,2,4,1,2],
'col_b': [2,2,[2,5,4],4,[1,5,6,3,2]]})
dt
id col_a col_b
0 a 1 2
1 a 2 2
2 a 4 [2, 5, 4]
3 b 1 4
4 b 2 [1, 5, 6, 3, 2]
</code></pre>
<p>and execute same code:</p>
<pre><code>np.isin(dt['col_a'], dt['col_b'])
</code></pre>
<p>I get correct result:</p>
<pre><code>array([False, True, True, False, True])
</code></pre>
<p>Can someone please let me know why it's giving different results.</p>

74,402,004 | <p>We are using the Azure DevOps server 2019 and we created agent pool and configure two agents in single server. Now my problem is when am trying to run the two pipelines on this pool parallel, anyone of them cancelling after few minutes with error: The operation was cancelled without any logs. I don't know why it is happening. Single job is running successfully but on parallel jobs, anyone pipeline failing with above error. Is this cause because of running two agents in single server, building on single msbuild. Please someone help me on this. Attaching few pipeline screenshots.

<p>I do understand that the max of an empty set is -Inf. This is mentioned in ?max.</p>
<p>That explains why the rollapply at the <em><strong>second</strong></em> position is -Inf. I think that at the second position, we remove the 2 NA's on position 1 and 2, and we are left with an empty set and hence the max is -Inf.</p>
<p>My query is : Why is the rollapply at the first position NA?</p>
<p>Should it also not be -Inf? Can someone please explain? What is the rationale behind it ?</p>

74,402,123 | <p>I am trying to parse a dataframe column called <code>'tags'</code> that contains a list of dicts and as an output create a list of the values of the key <code>var1</code>:</p>
<p>Dataframe column 'tags' example value:</p>
<pre><code>[{'var1': 'blue','var2': 123,'var3': 888},{'var1': 'red','var2': 123,'var3': 888},{'var1': 'green','var2': 123,'var3': 888}]
</code></pre>
<p>desired output:</p>
<pre><code>['blue', 'red', 'green']
</code></pre>
<p>code:</p>
<pre><code>d = [{f'{k}{i}': v for i, y in enumerate(x, 1) for k, v in y.items() if k == 'var1'} for x in df['tags']]
df = pd.DataFrame(d, index=df.index).sort_index(axis=1)
</code></pre>
<p>However this produces the following error:</p>
<pre><code>Type Error: 'float' object is not iterable
</code></pre>
<p>I have tried converting both <code>i</code> and <code>v</code> to a string using <code>str(i)</code> and <code>str(v)</code>, however I am still getting the same error.</p>
<p>What am I doing wrong?</p>

74,402,173 | <p>I am implementing a checkout page using Laravel and Vue.js. Test cards that don't require 3D Secure work well (e.g. 4242 4242 4242 4242). Test cards that require the customer to complete 3D Secure 2 authentication (e.g. 4000000000003220) also work(The pop up shows up after I call the confirmCardSetup method).</p>
<p>However, test cards that require the customer to complete 3D Secure (not 3D Secure 2) authentication (e.g. 4000000000003063) don't bring the pop up after calling the confirmCardSetup method. They are then subsequently declined on my backend with error</p>
<pre><code>Your card was declined. This transaction requires authentication.
</code></pre>
<p>Here is my confirmCardSetup method which is supposed to bring up the pop up.</p>
<pre class="lang-js prettyprint-override"><code>const result = await this.stripe.confirmCardSetup(
this.intentToken.client_secret,
{
payment_method: {
card: this.cardElement,
billing_details: {
name: this.frontUser.name,
},
}
}
);
</code></pre>
<p>I have tried adding off_session to false. I have also tried setting request_three_d_secure to 'any' with no luck.</p>

<p>But for me would make more sense to generate compilation warning as precision would be lost. Why not?</p>

74,402,236 | <p>I am new to Programming and got stuck in it. I wanted to calculate the hourly temperature variation of an object throughout the year using some variables, which changes in every hour. The original data contains 60 columns and 8760 rows for the calculation.</p>
<p>I got the desired output using the <code>for</code> loop, but the model is taking a lot of time for the calculation. I wonder if there is any way to replace the loop with functions, which I suspect, can also increase the speed of the calculations.</p>
<p>Here is a small reproducible example to show what I did.</p>
<pre><code>table <- data.table("A" = c(1), "B" = c(1:5), "C" = c(10))
table
</code></pre>
<pre><code> A B C
1: 1 1 10
2: 1 2 10
3: 1 3 10
4: 1 4 10
5: 1 5 10
</code></pre>
<p>The <code>for</code>loop</p>
<pre><code>for (j in (2: nrow(table))) {
table$A[j] = (table$A[j-1] + table$B[j-1]) * table$B[j]
table$C[j] = table$B[j] * table$A[j]
}
</code></pre>
<p>I got the output as I desired:</p>
<pre><code> A B C
1: 1 1 10
2: 4 2 8
3: 18 3 54
4: 84 4 336
5: 440 5 2200
</code></pre>
<p>but it took 15 min to run the whole program in my case (not this!)</p>
<p>So I tried to use function instead of the <code>for</code> loop.</p>
<p>I tried this:</p>
<pre><code>table <- data.table("A" = c(1), "B" = c(1:5), "C" = c(10))
myfun <- function(df){
df = df %>% mutate(A = (lag(A) + lag(B)) * B,
C = B * A)
return(df)
}
myfun(table)
</code></pre>
<p>But the output was</p>
<pre><code> A B C
1 NA 1 NA
2 4 2 8
3 9 3 27
4 16 4 64
5 25 5 125
</code></pre>
<p>As it seems that the function refers to the rows of the first table not the updated rows after the calculation. Is there any way to obtain the desired output using functions? It is my first R project, any help is very much appreciated. Thank you.</p>

74,402,306 | <p>How can I avoid doing embarrassing stuff like this when trying to apply multiple regular expressions using the <code>gsub()</code> function in jq?</p>
<pre><code>."values" | tostring | gsub("\"";"`") | gsub("\\[";"") | gsub("\\]";"") | gsub("=\\w*";"")
</code></pre>
<p>I want to convert the array below to a string, keep the values to the left of the equals sign and surround each value in backticks.</p>
<p>The jq command above works but something tells me there's a more elegant solution.</p>
<p>Input:</p>
<pre class="lang-json prettyprint-override"><code>{
"values": [
"1=foo",
"2=bar",
"3=baz"
]
}
</code></pre>
<p>Output (expected and actual)</p>
<pre class="lang-json prettyprint-override"><code>"`1`,`2`,`3`"

74,402,327 | <p>I have created a click event listener then added a function in it which conatin some parameters, according to that parameters i am creating an audio element, which i play in further steps. Problem arises when i wish to pause that same audio after detecting another click, it never happens because it creates a new audio element on every click with same values and pause it, although that new audio element was never played and the first audio element created keeps playing.</p>
<pre><code>let check = true;
masterPlayButton.addEventListener("click", function (i) {
minorPlayPause(i);
});
</code></pre>
<pre><code>function minorPlayPause(x) {
let audio = new Audio("songs/" + x + ".mp3");
if (check == true) {
check = false;
audio.play();
};
} else {
check = true;
audio.pause();
}
}
</code></pre>
<p>I tried creating audio element outside the event listener so that everytime a new audio element is not created but it doesnt work because i want to create audio element according to the parameters provided from click data.
Also, i tried to put another event listener inside the 'if' (as written in the provided code) to detect the pause on the same audio element, but it didnt worked.
I just want to pause the same audio on second click.</p>
<p>A helping hand is most appreciable !!</p>

74,402,347 | <p>I have a question about the function "Analyse in Excel" or "Analyse in Excel" in German when a PBI (Power BI) report has been published.</p>
<p><a href="https://i.stack.imgur.com/UykvQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UykvQ.png" alt="enter image description here" /></a></p>
<p>I read in a flat table in PBI and create some measures in PBI. Basically, it's about account numbers and the limits. A calculation is not necessary or possible here.</p>
<p>If I now want to analyse the data in Excel Pivot Table, I can only display the measures as values. An analysis of account numbers and limits is not possible, as limits are not measures.</p>
<p>What do I have to do to be able to select original data as values?</p>
<p>Thank you very much for your feedback and best regards
Andi</p>

74,402,364 | <p>I got this type of sport activity data in excel:
<a href="https://i.stack.imgur.com/WQsMv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WQsMv.png" alt="sports data" /></a>
I try to pull just a "calorie" value from column D to another cell.
Any suggestions how to pull this data?</p>
<p>Tried to do it by =MID function, but those strings are different length.
Any suggestions how to pull this data?</p>

74,402,385 | <p>So i am working with classes and if statements. When the if statement is inside the class def, it seems to be ignored and not sure what i am doing wrong. I want it to raise an exception if the criteria is not met.</p>
<p>I tried to change name to __name but that did not seem to help. I also tried to remove def get_name(self) to see if that caused the problem but it did not.</p>
<pre><code>class Strict:
name:str
def __init__(self,name):
self.name = name
def get_name(self):
return self.name
def set_name(self,name):
if len(name) != 5:
raise Exception("Name must be exactly 5 characters")
else:
return name
try:
z = Strict("ABCDEFGH")
print(z.name)
except Exception as e:
print(str(e))

74,402,488 | <p>I have a question about the 'continue' function in Python. I wolud like to skip 'Antarctic' in the following list:</p>
<pre><code>continents = = ["Afrika", "Antarktic", "Asien", "Australia", "Europe", "North America", "South America"]
</code></pre>
<p>I thought about using the for loop in combination with the 'continue' function but it doesn't work. Maybe I have to transform the list in another format or so.</p>
<p>This was my first guess.</p>
<pre><code>for i in continents:
if i == 1:
continue
print(i)
</code></pre>
<p>Thanks in advance.</p>

74,402,546 | <p><strong>Requirement:</strong> Is there any optimal or easy way to filtered out the objects from an array which contains a specific property based on its value without <em>recursion</em>.</p>
<p><strong>Problem statement:</strong> We can achieve this requirement using recursion but as data set (array of objects) is very large and each object contains <code>n</code> number of nested objects, Recursion approach is causing performance issue.</p>
<p>Here is the sample mock data:</p>
<pre><code>[{
children: [{
children: [{
children: [],
isWorking: 'yes'
}]
}]
}, {
children: [],
isWorking: 'no'
}, {
children: [{
children: [{
children: [],
isWorking: 'no'
}]
}]
}, {
children: [{
children: [],
isWorking: 'yes'
}]
}, ...]
</code></pre>
<ul>
<li>I want to filter out the root objects from an array which contains nested <code>isWorking</code> property with the value as <code>yes</code>.</li>
<li><code>isWorking</code> property will only available for the objects which does not contains children. i.e. <code>children: []</code></li>
</ul>
<p>As I said earlier, I am able to achieve this by recursion but looking for a optimal solution which will not impact the performance.</p>
<p>This is what I tried (Working solution):</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>const parent = [{
children: [{
children: [{
children: [],
isWorking: 'yes'
}]
}]
}, {
children: [],
isWorking: 'no'
}, {
children: [{
children: [{
children: [],
isWorking: 'no'
}]
}]
}, {
children: [{
children: [],
isWorking: 'yes'
}]
}];
const isWorkingFlagArr = [];
function checkForOccupation(arr) {
arr.forEach(obj => {
(!obj.children.length) ? isWorkingFlagArr.push(obj.isWorking === 'yes') : checkForOccupation(obj.children)
})
}
checkForOccupation(parent);
const res = parent.filter((obj, index) => isWorkingFlagArr[index]);
console.log(res);</code></pre>

goalList.sort((a, b)=> a.compareTo(b['objectiveStartDate']));

<p>IN goal Objective (GoalCardData(<em>goal</em>: goalList[index]),) I have attributes(title, startDate, amount, salary etc.) , so when we create a goal it has date. But when i list them its just randomly saving.</p>

74,402,607 | <p>I am trying to create a new worksheet in a Google Sheets doc where I need to filter a Master data set based on values in a specific column.</p>
<p>I originally did a VLOOKUP in each specific column that I wanted returned but it brough back blank rows for the corresponding rows that did not match, and eventually it broke for some reason and stopped returning the correct data.</p>
<p>I have been trying to find a new way to do it and have most recently been trying XLOOKUP, but it returns duplicate rows of each correct match.</p>
<p>The original datasheet is mostly populated itself by VLOOKUPS, drawing in information from other trackers so I feel this must be why it is falling over.</p>
<p>The dataset looks roughly like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>Y/N</th>
<th>Last Name</th>
<th>First Name</th>
<th>col</th>
<th>col1</th>
<th>col2</th>
<th>etc</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Y</td>
<td>SMITH</td>
<td>A</td>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 1</td>
<td>Cell 2</td>
</tr>
<tr>
<td>2</td>
<td>N</td>
<td>JONES</td>
<td>B</td>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 1</td>
<td>Cell 2</td>
</tr>
</tbody>
</table>
</div>
<p>There are 40+columns in the tracker but I basically want to have a new sheet where I filter and return only the 'Y' values in the Y/N column, and return columns A:N (including the ID column) without leaving blank rows between the matches, and without returning dupllicates.</p>
<p>I have tried everything I can think of but I just cannot make it work, so any help on the matter would be GREATLY appreciated.</p>
<p>Thanks for reading.</p>

I Have a column named N_AIH, and I have another column named IDENT, it contains the values 1 and 5.</p>
<p>I need to create A new column 'LP' with the following condition: if the same N_AIH value repeats on IDENT 1 and 5.</p>
<p>data:</p>
<pre><code>N_AIH IDENT

74,402,677 | <p>I have a single cell that contains several sets of text separated by a semi colon (extracted from another application) for example</p>
<p>Cell A1: apple;banana;orange
Cell A2: banana;orange;melon</p>
<p>I am trying to introduce a formula in an adjacent cell which will return a value for apple if it contains apple, or banana if it contains banana.</p>
<p>I am happy to have it only return a single value (the first one perhaps)</p>
<p>I tried the IF function using <> as suggested on the internet.
I thought this had worked to start with but then it didnt return the value when I moved it! - so it was clearly wrong.</p>
<p>=IF(A1<>"apple","apple","") - returned apple - but then always returned apple even if there was no apple in the string.</p>
<p>I did then try an IFS nested statement - but that didnt work - highly likely because I then realised that even my IF statement didnt work properly.
I tried to research ISNUMBER and a couple of other suggestions but cant seem to get it anywhere near working!</p>
<p>It seems like it is something relatively straightforward and I am just missing the obvious - would welcome any assistance.</p>

74,402,695 | <p>I have a multi-line template literal. I want to splice it based on line number and character index in the line. For that, I need the number of characters in a given line. How can I get this number?</p>
<p>As for what I have tried, well, I pretty much only put random numbers into <code>slice()</code> to see how much it slices.</p>
<p>Thanks.</p>

# Step 2: plot the data
plot = sns.scatterplot(data=grades, x="Hours", y="GPA")
fig = plot.get_figure()
fig.savefig("out.png")

<p>Using the data set</p>
<pre><code>Hours,GPA,Hours,GPA,Hours,GPA

74,402,717 | <p>I am just starting out with OOP and trying to understand the code below. Why is book2 object changing its value even though i am not defining it to something els just using that object to define the values of the objects in books array.</p>
<pre><code>Book[] books = new Book[5];
Book book2 = new Book("test", "test1", 800);
for (int i = 0; i < books.Length; i++)
{
books[i] = book2;
Console.WriteLine(books[i].pages);
books[i].pages += 10;
}

<p>Is there something fundemental i have missed about objects? In my thinking this code should return 800, 5 times.</p>

74,402,744 | <p>For some objects an attribute identifies a special column, for example the geometry column in an <code>sf</code> object. For conducting some calculations in <code>dplyr</code> it would be good to easily identify these columns. I'm searching for a way to create a function that helps identifying this column. In the example below I can make a function that identifies this column but I still need to use the <code>rlang</code> splice operator (<code>!!!</code>).</p>
<pre class="lang-r prettyprint-override"><code>require(sf)
require(dplyr)
n<-4
df = st_as_sf(data.frame(x = 1:n, y = 1:n, cat=gl(2,2)), coords = 1:2, crs = 3857) %>% group_by(cat)
# this is the example I start from however the geometry column is not guaranteed to have that name
df %>% mutate(d=st_distance(geometry, geometry[row_number()==1]))
#> Simple feature collection with 4 features and 2 fields
#> Geometry type: POINT
#> Dimension: XY
#> Bounding box: xmin: 1 ymin: 1 xmax: 4 ymax: 4
#> Projected CRS: WGS 84 / Pseudo-Mercator
#> # A tibble: 4 × 3
#> # Groups: cat [2]
#> cat geometry d[,1]
#> * <fct> <POINT [m]> [m]
#> 1 1 (1 1) 0
#> 2 1 (2 2) 1.41
#> 3 2 (3 3) 0
#> 4 2 (4 4) 1.41
# this works, however the code does not get easier to read
df %>% mutate(d=st_distance(!!!syms(attr(., "sf_column")), (!!!syms(attr(., "sf_column")))[row_number()==1]))
#> Simple feature collection with 4 features and 2 fields
#> ...
#> 4 2 (4 4) 1.41
# this works and is already better:
geometry_name<-function(x) syms(attr(x, 'sf_column'))
df %>% mutate(d=st_distance(!!!geometry_name(.), (!!!geometry_name(.))[row_number()==1]))
#> Simple feature collection with 4 features and 2 fields
#> ...
#> 4 2 (4 4) 1.41
</code></pre>
<p>Ideally I would like to find a function that makes the following code work as this would be easiest for users:</p>
<pre class="lang-r prettyprint-override"><code>df %>% mutate(d=st_distance(geometry_name(), geometry_name()[row_number()==1]))
</code></pre>
