74,443,983 | <p>I have an UICollectionView built programatically that doesn't allow me to scroll to the last item in it.</p>
<p><a href="https://i.stack.imgur.com/g4Ybt.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/g4Ybt.gif" alt="" /></a></p>
<p>Here is how I set it up</p>
<pre><code>private let collectionView: UICollectionView = UICollectionView(

collectionViewLayout: UICollectionViewCompositionalLayout { sectionIndex, _ -> NSCollectionLayoutSection? in
return WorkoutListViewController.createSectionLayout(section: sectionIndex)

)
item.contentInsets = NSDirectionalEdgeInsets(top: 14, leading: 0, bottom: 14, trailing: 0)
// group
let verticalGroup = NSCollectionLayoutGroup.vertical(

</code></pre>
<p>I tried modifying the height by giving it a very large number (e.g 2000) and nothing changed. I also tried adding the <code>UICollectionViewDelegateFlowLayout</code> protocol to add the</p>
<pre><code>func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
}
</code></pre>
<p>function and return the <code>CGSize</code> of my item.</p>

74,443,993 | <p>We have a lakehouse architecture with Hive metastore tables. I want to do processing on this data, so I select my data as Spark dataframe.</p>
<p>The specific processing step I wanted to achieve was parsing date columns in my Spark Dataframes that come in a rather strange format: <code>/Date(1582959943313)/</code>, where the number inside /Date(xx)/ is miliseconds since epoch. I thought I was being clever by converting my Spark DF <code>toPandas()</code> and then process the dates:</p>
<pre><code>df_accounts = spark.sql("SELECT * FROM database.accounts")
df_accounts_pandas = df_accounts.toPandas()
df_accounts_pandas['ControlledDate'] = df_accounts_pandas['ControlledDate'].str.slice(start=6, stop=-2)
df_accounts_pandas['Created'] = df_accounts_pandas['Created'].str.slice(start=6, stop=-2)
df_accounts_pandas['ControlledDate'] = pd.to_datetime(df_accounts_pandas['ControlledDate'], unit='ms', origin='unix')
df_accounts_pandas['Created'] = pd.to_datetime(df_accounts_pandas['Created'], unit='ms', origin='unix')
</code></pre>
<p>This works fine. Now the next step would be to convert the df <em>back</em> to a Spark Dataframe, and be done with it.</p>
<pre><code>df_accounts = spark.createDataframe(df_accounts_pandas)
</code></pre>
<p>This throws a <code>ValueError: Some of types cannot be determined after inferring</code></p>
<p><a href="https://stackoverflow.com/questions/40517553/pyspark-valueerror-some-of-types-cannot-be-determined-after-inferring">This SO Question</a> tells me to either manually define a schema or drop Null columns. But why do I have to make this choice? I don't understand why I was able to do the conversion the other way around, but now cannot convert back.</p>
<p>Are there any other workarounds? My tables have 100's of columns so I don't want to manually define a schema. I don't know if columns that are NULL now will be NULL in the future.</p>
<p>P.S. - Am rather new to spark ecosystem - Is it even a good idea to do processing in pandas like this? (I would like to since it has more options than regular PySpark) Or are there better ways to use pandas functionality on Spark dataframes?</p>

74,444,011 | <p>I'm trying to implement normalized binary cross entropy for a classification task following this paper: <a href="https://arxiv.org/pdf/2006.13554.pdf" rel="nofollow noreferrer">Normalized Loss Functions for Deep Learning with Noisy Labels</a>.
The math is as follows:
<a href="https://i.stack.imgur.com/leXDb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/leXDb.png" alt="enter image description here" /></a></p>
<p>Here is my implementation:</p>
<pre><code>import tensorflow as tf
from keras.utils import losses_utils
class NormalizedBinaryCrossentropy(tf.keras.losses.Loss):
def __init__(
self,
from_logits=False,
label_smoothing=0.0,
axis=-1,
reduction=tf.keras.losses.Reduction.NONE,
name="normalized_binary_crossentropy",
**kwargs
):
super().__init__(
reduction=reduction, name=name
)
self.from_logits = from_logits
self._epsilon = tf.keras.backend.epsilon()
def call(self, target, logits):
if tf.is_tensor(logits) and tf.is_tensor(target):
logits, target = losses_utils.squeeze_or_expand_dimensions(
logits, target
)
logits = tf.convert_to_tensor(logits)
target = tf.cast(target, logits.dtype)
if self.from_logits:
logits = tf.math.sigmoid(logits)
logits = tf.clip_by_value(logits, self._epsilon, 1.0 - self._epsilon)
numer = target * tf.math.log(logits) + (1 - target) * tf.math.log(1 - logits)
denom = - (tf.math.log(logits) + tf.math.log(1 - logits))
return - numer / denom
def get_config(self):
config = super().get_config()
config.update({"from_logits": self._from_logits})
return config
</code></pre>
<p>I'm using this loss to train a binary classifier (CTR predictor), but loss of the model does not decrease and ROC-AUC remains at ~0.49-0.5. To verify the implementation of numerator, I tried training by removing the denominator and it's working fine.</p>
<pre><code># Example Usage
labels = np.array([[0], [1], [0], [0], [0]]).astype(np.int64)
logits = np.array([[-1.024], [2.506], [1.43], [0.004], [-2.0]]).astype(np.float64)
tf_nce = NormalizedBinaryCrossentropy(
reduction=tf.keras.losses.Reduction.NONE,
from_logits=True
)
tf_nce(labels, logits)
#<tf.Tensor: shape=(5, 1), dtype=float64, numpy=
# array([[0.18737159],
# [0.02945536],
# [0.88459308],
# [0.50144269],
# [0.05631594]])>
</code></pre>
<p>I checked manually with some extremes and that loss doesn't hit nans or 0s.</p>
<p>Can anyone help me in debugging why the model is not able to converge on this loss? Is there something wrong with my understanding of the loss function or implementation?</p>
<p>Edit 1: Model architecture is a Multi-Gate Mixture-of-Experts with 6 tasks. All 6 tasks are binary classification and losses from all tasks are added together to get final loss.</p>

<p>Now if I write blog - blog input clears.
Funny thing is that you can write name inside blog input and text in name input clears.
Same way If I write blog inside name input - blog input text clears.</p>
<p>I guess I'm making some dumb mistake, what am I doing wrong ? :)</p>

74,444,118 | <p>I'm trying to understand this auto-increment formula, that my colleague has written. I understand how <strong>arrayformula</strong> usually works and also <strong>countifs</strong>.</p>
<p>Formula from the screen: <code>=ARRAYFORMULA(COUNTIFS(ROW(B2:B), "<="&ROW(B2:B)))</code></p>
<p>I'm stacked about why ROW(B2:B) (1param in COUNTIFS) as a range works fine. It should be a range, not just a number that <strong>ROW</strong> function returns.</p>
<p>I have been trying to find an answer, read documentation, but nothing helped.</p>
<p>I think that, for example, for 4th line the formula would look like this (if we seperate from ARRAYFORMULA):</p>
<p>COUNTIFS(<strong>ROW(B4:B</strong>), "<="&ROW(B4:B)),</p>
<p>COUNTIFS(<strong>4</strong>, "<=4")</p>
<p>I need to understand this code, not other solutions.</p>

74,444,186 | <p>I am migrating d3 to newer version 7.6.1, now the version which i am using is 5.15 and it has one method which is <strong>d3.entries</strong> and in version 7.6.1 it is deprecated.</p>
<p>As far as i know this d3.entries is used to convert object to array of object for example -</p>
<pre><code>chart.data = function(value,newName,newColor,sorted) {
varColor=newColor;
varSorted=sorted;
displayData = d3.entries(value); //version 5.15
console.log("-----");
console.log(displayData);
assignedName = newName;
return chart;
}
</code></pre>
<pre><code>{Metrics: 404, Asset: 492, B7: 84} to [{'Metrics',404}, {'Asset': 492}, {'B7': 84}]
</code></pre>
<p>but when i upgrade my d3 version this d3.entries() function is not there so i used <strong>Object.entries()</strong> -</p>
<pre><code>chart.data = function(value,newName,newColor,sorted) {
varColor=newColor;
varSorted=sorted;
displayData = Object.entries(value); //version 7.6
console.log("-----");
console.log(displayData);
assignedName = newName;
return chart;
}
</code></pre>
<pre><code>My Output is -
[['Metrics',404], ['Asset': 492], ['B7': 84]]
</code></pre>
<p>but still i am not getting the desired output.</p>

74,444,195 | <p>I have a windows forms timer with an async callback that await a database operation, why the await is executed again even before the previous callback has not finished yet? How can I fix this?
Many people say that System.Windows.Forms.Timer wait that previous callback operation finishes before executing new one.</p>
<pre><code>Private Async Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
' I have an array with 6 elements that i control
' for executing database operation
For i=1 To 6
If(some condition is true in array index)
Await SaveAsync()
'set to false the condition in array index after save
End If
Next
End Sub
</code></pre>
<p>Thanks in advance.</p>

if ($index !== null)
{
unset($downloadArray[$index]);
die("found index: " . $index);

<p><code>$download->name</code> contains <code>'eyetyy'</code><br/>
<code>$downloadArray</code> is my array<br/>
But it always dies and doesn't show any index on screen.<br/>

74,444,269 | <p>Hei,</p>
<p>i have a question about the best practice here. I have a Golang Project which uses as Postgres Database and specific Migrations. The Database has many tables and some depend on each other (Table A has FK to Table B, Table B has FK to Table A). My "problem" is now that i have to import data from CSV files, which i do with the COPY ... FROM ... WITH Command. Each CSV file contains the Data for a specific table.</p>
<p>If i try to use the copy command i get the error: "insert or update on table "b" violates foreign key constraint". Thats right, because in table a is no data right now. And cause of the FKs the problem happens on both sides.</p>
<p>So what is the best way to import the data?</p>
<p>Thanks :)</p>

74,444,290 | <p>I have an Angular Material Paginator which I am currently customizing the css of.</p>

<p><a href="https://i.stack.imgur.com/peKB4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/peKB4.png" alt="enter image description here" /></a></p>
<p>I cant record my screen on my device so I will explain.</p>
<p>The two arrow buttons on the right side are Angular Material Icon Buttons.</p>
<p>When I click them, a ripple effect (gray circle) appears. I need to delete that ripple effect.</p>
<p>I couldn't inspect the element where it happens because it only appears on a click.</p>
<p>I checked SO already about this question and the most common answer, to use <code>[disableRipple]="true"</code> doesn't work here, since angular paginator does not have this property. I am working in a big project with several developers, so I would not like to touch global scss files.</p>
<p>This is my code btw:</p>
<pre><code><mat-paginator
#paginator
(page)="changePage($event)"
[length]="imagesAndFiles.length"
[pageIndex]="pageIndex"
[pageSize]="pageSize"
[pageSizeOptions]="[4, 8, 16, 24, 32]"
>
</mat-paginator>
</code></pre>
<p>How can I remove the ripple effect from the arrow buttons?</p>

The state variable from useState is a set and has is a set build-in function. Why this error happens?</p>

74,444,370 | <p>looking for a way to remove open unpaired tags!
BS4 as well as lxml are good at removing unpaired closed tags.
But if they find an open tag, they try to close it, and close it at the very end :(</p>
<p>Example</p>
<pre><code>from bs4 import BeautifulSoup
import lxml.html
codeblock = '<strong>Good</strong> Some text and bad closed strong </strong> Some text and bad open strong PROBLEM HERE <strong> Some text <h2>Some</h2> or <h3>Some</h3> <p>Some Some text <strong>Good2</strong></p>'
soup = BeautifulSoup(codeblock, "html.parser").prettify()
print(soup)
root = lxml.html.fromstring(codeblock)
res = lxml.html.tostring(root)
print(res)
</code></pre>
<p>Output bs4:</p>
<pre><code><strong>
Good
</strong>
Some text and bad closed strong
Some text and bad open strong PROBLEM HERE
<strong>
Some text
<h2>
Some
</h2>
or
<h3>
Some
</h3>
<p>
Some Some text
<strong>
Good2
</strong>
</p>
</strong>
</code></pre>
<p>Output lxml:</p>
<pre><code>b'<div><strong>Good</strong> Some text and bad closed strong Some text and bad open strong PROBLEM HERE <strong> Some text <h2>Some</h2> or <h3>Some</h3> <p>Some Some text <strong>Good2</strong></p></strong></div>'
</code></pre>
<ol>
<li>I would be fine if the tag is closed before the first following tag, here in the example of H2</li>
</ol>
<pre><code>PROBLEM HERE <strong> Some text </strong><h2>Some</h2>
</code></pre>
<ol start="2">
<li>I would also be ok with removing this open tag <code><strong></code></li>
</ol>
<p>But the fact that it closes at the very end - this is a problem!</p>
<p><strong>In the real code the index (position) of the tag <code><strong></code> is not known!</strong></p>
<p>What are the solutions?</p>
<p>I tried to do it with BS4 and lxml but it didn't work!
If you know the solution, please help!</p>

74,444,395 | <p>I have a log files that I read/stream into Python (it contains timestamp and data) using tail.</p>
<p>I need a way to see if, in the last 10 seconds, how many lines were seen/observed based on a filter (e.g. line contains "error")</p>
<p>I'll be checking every X seconds to see how many lines were present for "error" or "debug" etc... The count should only look at the last X seconds.</p>
<p>Example:</p>
<p>A log file which Python tails is</p>
<pre class="lang-none prettyprint-override"><code>2022-11-15 14:00:00,000 : Error 1923
2022-11-15 14:00:01,000 : Error 1456
2022-11-15 14:00:01,400 : Error 1001
2022-11-15 14:00:03,400 : Error 1124
2022-11-15 14:00:05,400 : Normal 0011
2022-11-15 14:00:06,400 : Error 1123
</code></pre>
<p>When I read the file, in Python; I want to answer the question</p>
<p><em>In the last X seconds, how many times have I seen Error or How many times have I seen Normal?</em></p>
<p>How would I accomplish this whilst I tail a file to check the last 10 seconds or 20 seconds etc.?</p>

74,444,460 | <p>My knowledge till now was that arrays in C and CPP/C++ have fixed sizes. However recently I encountered 2 pieces of code which seems to contradict this fact. I am attaching the pics here. Want to hear everyone's thoughts on how these are working. Also pasting the code and doubts here:</p>
<p>1.</p>
<pre><code>#include <iostream>
#include <string.h>
using namespace std;
int main()
{
char str1[]="Good"; //size of str1 should be 5
char str2[]="Afternoon"; //size of str2 should be 10
cout<<"\nSize of str1 before the copy: "<<sizeof(str1);
cout<<"\nstr1: "<<str1;
strcpy(str1,str2); //copying str1 into str2
cout<<"\nSize of str1 after the copy: "<<sizeof(str1);
cout<<"\nstr1: "<<str1;
return 0;
}
</code></pre>
<p><code>your text</code>
O/P:
Size of str1 before the copy: 5
str1: Good
Size of str1 after the copy: 5
str1: Afternoon</p>
<p>In first snippet I am using strcpy to copy char str2[] contents that is "Afternoon" into char str1[] whose size is 5 less than size of str2. So theoritically the line strcpy(str1,str2) should give error as size of str1 is less than size of str2 and fixed. But it executes, and more surprising is the fact that even after str1 contain the word "afternoon" the size is still the same.</p>
<p>2.</p>
<pre><code>#include <iostream>
#include <cstring>
using namespace std;
int main()
{
char first_string[10]; // declaration of char array variable
char second_string[20]; // declaration of char array variable
int i; // integer variable declaration
cout<<"Enter the first string: ";
cin>>first_string;
cout<<"\nEnter the second string: ";
cin>>second_string;
for(i=0;first_string[i]!='\0';i++);
for(int j=0;second_string[j]!='\0';j++)
{
first_string[i]=second_string[j];
i++;
}
first_string[i]='\0';
cout<<"After concatenation, the string would look like: "<<first_string;
return 0;
}
</code></pre>
<p>O/P:
Enter the first string: good</p>
<p>Enter the second string: afternoon</p>
<p>After concatenation, the string would look like: goodafternoon</p>
<p>Here also even if I provide a string of length 20 as input to second_string[] it's still able to concatenate both the strings and put them in first_string[], even though the size of the concatenated string will be clearly greater than size of first_string[] which is 10.</p>
<p>I tried to assign a string of greater length to a string variable of smaller length. techincally it should not work but it worked anyway</p>

<p>I would like to filter these dictionaries in such a way as to print only those keys and values in which <strong>"detected": true</strong>.</p>
<p>For example I would like print only</p>
<pre><code>{

<p>I use VirusTotal apikey v2 <a href="https://developers.virustotal.com/v2.0/reference/domain-report" rel="nofollow noreferrer">https://developers.virustotal.com/v2.0/reference/domain-report</a>
My code in python:</p>
<pre><code>parameters = {'apikey': api_key, 'resource': domain}
response = requests.get(url, params=parameters)
python_response = json.loads(response.text)
scans = python_response["scans"]
example = json.dumps(python_response["scans"], indent=4)
print(example)
</code></pre>
<p>I'm looking for a simple and readable way to do it so that I understand it as best I can. I would like print result in Python. I searched and read various solutions for this (list comprehension or filter() with lambda), but it did not help me.</p>
<p>I'm still learning, thanks in advance for your understanding if it's a simple case.</p>
<p>Thank you in advance for your help and answers.</p>

74,444,519 | <p>I'm trying to find an efficient way to merge two list of python objects (classes) with diferent structures and merge them into a new list of new object. The code:</p>
<pre class="lang-py prettyprint-override"><code>from datetime import datetime
class StructureOne(object):
def __init__(self, date_time: datetime, name: str):
self.date_time: datetime = date_time
self.name: str = name
self.value = None
def set_value(self,value:float):
self.value = value
class StructureTwo(object):
def __init__(self, date_time: datetime, value: float):
self.date_time = date_time
self.value: float = value
def merge_lists(list_one: list[StructureOne], list_two: list[StructureTwo]) -> list[StructureOne]:
for element_one in list_one:
i = 0
while i < len(list_two) and element_one.value is None:
if element_one.date_time == list_two[i].date_time:
element_one.set_value(value=list_two[i].value)
i += 1
return list_one
list_one: list[StructureOne] = [
StructureOne(date_time=datetime(2022, 1, 1, 0), name='zero'),
StructureOne(date_time=datetime(2022, 1, 1, 1), name='one'),
StructureOne(date_time=datetime(2022, 1, 1, 2), name='two'),
StructureOne(date_time=datetime(2022, 1, 1, 3), name='three'),
]
list_two: list[StructureTwo] = [
StructureTwo(date_time=datetime(2022, 1, 1, 0), value=0),
StructureTwo(date_time=datetime(2022, 1, 1, 1), value=1),
StructureTwo(date_time=datetime(2022, 1, 1, 2), value=2),
StructureTwo(date_time=datetime(2022, 1, 1, 3), value=3),
]
merged_list: list[StructureOne] = merge_lists(list_one=list_one, list_two=list_two)
</code></pre>
<p>The desired result is</p>
<pre class="lang-py prettyprint-override"><code>
list_one: list[StructureOne] = [
StructureOne(date_time=datetime(2022, 1, 1, 0), name='zero', value=0),

74,444,534 | <p>I can't get this result: I need to have a date table (in YYYY-MM-DD format), where each date would contain requests.
Let me explain, basically I browse an already existing date table, which contains the dates of my requests.
And after this date array browsing, I build my new array which contains the date on which the array is positioned, as a key, and the associated request obtained by the call to my API.</p>
<p>So I have an array of the style (in the code snippet, dateArray[i] corresponds to the date on which the date array is positioned):</p>
<p>Here is the table daysRequests:</p>
<pre class="lang-js prettyprint-override"><code>[{
date: dateArray[i],
requests: [idRequestX]
},
{
date: dateArray[i],
requests: [idRequestX, idRequestY]
}]
</code></pre>
<p>And here is the push I do there:</p>
<pre class="lang-js prettyprint-override"><code>this.daysRequests.push({
day: dateArray[i],
requests: [idRequest]
});
</code></pre>
<p>Currently the push in the array creates duplicates for me, because if a date has several requests, it is not able to look for the record in the array corresponding to the already existing date and add in the requests sub-array, the new request.</p>
<p>I don't know how to check that the date already exists in the table and if it does, add the id of the new request in its sub table.</p>
<p>The complexity is that it is a key-value dictionary containing an array.</p>
<p>And that, I can't manage.</p>
<p>Does anyone have an idea?</p>

74,444,548 | <p>I wrote a lexical analyzer for cpp codes in python, but the problem is when I use input.split(" ") it won't recognize codes like x=2 or function() as three different tokens unless I add an space between them manually, like: x = 2 .
also it fails to recognize the tokens at the beginning of each line.
(if i add spaces between each two tokens and also at the beginning of each line, my code works correctly)</p>
<p>I tried splitting the code first by lines then by space but it got complicated and still I wasn't able to solve the first problem.
Also I thought about splitting it by operators, yet I couldn't actually implement it. plus I need the operators to be recognized as tokens as well, so this might not be a good idea.
I would appreciate it if anyone could give any solution or suggestion, Thank You.</p>
<pre><code>f=open("code.txt")
input=f.read()
input=input.split(" ")
</code></pre>
<pre><code>f=open("code.txt")
input=f.read()
input1=input.split("\n")
for var in input1:
var=var.split(" ")
</code></pre>

74,444,585 | <p>I am writing a job filtering system in Vuejs and when the user enters a letter in the search bar, it only filters through the first letter instead of the whole word.</p>
<p>Imagine I have a list with item "Banana". If the user types "Banana" into the search bar, the item "Banana" is returned, since the search matches the list item. When the user just types a singular letter i.e. "B" it displays all items with the letter B. However when another letter is followed by that "Ba" it returns nothing.</p>
<p>Below is the code that is causing me problems:</p>
<pre><code><script>
export default {
data(){
return{
searchQuery:'',
selectedItem: null,
isVisible: false,
userArray: [],
};
},
computed: {
filteredUser() {
const query = this.searchQuery.toLowerCase();
if(this.searchQuery === "" ) {
return this.userArray;
}
return this.userArray.filter((user) => {
return Object.values(user).some((word) =>
String(word).toLowerCase().includes(query)
);
});
},
},
</code></pre>
<p>Other aspects of this filter function are working (i.e. the ability to click on jobs) except this search function.</p>
<p>Any help would be greatly appreciated.</p>

74,444,640 | <p>I'm trying to set the <code>hosts</code> value in a ansible playbook dynamically. This means that in the <code>group_vars/all.yml</code> I have the correct IP for the host that ansible should use to connect. I have to do so, as I do not have the IP's beforehand. Prior to running the role described below, I run a role that creates the servers and only after that I have the IP's.</p>
<p>This is my <code>playbook.yml</code>:</p>
<pre><code>- name: do_something
hosts:
- "{{ NETWORK.IP }}"
roles:
- my_role

<p>and the file<code>group_vars/all.yml</code> looks like this:</p>

IP: 10.0.0.1

<p>and when I execute I get:</p>
<pre><code>$ ansible-playbook playbook.yml

ERROR! The field 'hosts' has an invalid value, which includes an undefined variable. The error was: 'NETWORK' is undefined
The error appears to be in 'playbook.yml': line X, column Y, but may
be elsewhere in the file depending on the exact syntax problem.
</code></pre>
<p><strong>I tried</strong> using different things such as</p>
<ul>
<li>in an earlier task on localhost using the set_facts module to set the variable</li>
<li>using the gather_facts in the playbook</li>
<li>using vars_file: group_vars/all.yml</li>
</ul>
<p><strong>Is it even possible to do like that? What am I doing wrong?</strong></p>
<hr />
<p>When I do something like this in the playbook:</p>
<pre><code>- name:
do_something2 hosts:
- LOCALHOST
tasks:
- set_fact:
MY_HOST: "{{ NETWORK.IP }}"
</code></pre>
<p>it is working. So I guess it has something to do with the 'all.yml' as the LOCALHOST is defined in a group. But <code>all.yml</code> should be possible to use even if the host is not defined in a group right?</p>
<hr />
<p><strong>Additional information</strong>:
This is the output of <code>ansible --version</code>:</p>
<pre><code>ansible [core 2.13.3]
config file = /etc/ansible/ansible.cfg
configured module search path = ['SOME_PATH', '/usr/share/ansible/plugins/modules']
ansible python module location = SOME_PATH

</code></pre>
<p>and I'm running it on openSUSE Leap</p>
<p>edit: added the description as of why I need to have it set dynamically (because I create the servers in an earlier role).</p>

74,444,665 | <p>I'm currently doing c++ with OpenCL, where a c-style struct is required to carry configuration information from the c++ host to the OpenCL kernel. Given that dynamically allocated arrays are not guaranteed to be supported by every OpenCL implementation, I must ensure every array accessible by the kernel code be static-sized. However, I run into weird errors when initializing static arrays within a c-style struct.</p>
<p>The error could be reproduced by the following PoC:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <cstring>
#include <string>
#define ID_SIZE 16
struct conf_t {
const unsigned int a;
const unsigned int b;
const unsigned char id[ID_SIZE];
};
int main() {
const std::string raw_id("0123456789ABCDEF");
unsigned char id[ID_SIZE];
memcpy(id,raw_id.c_str(),ID_SIZE);
struct conf_t conf = {10,2048,id};
}
</code></pre>
<p>And the following error:</p>
<pre><code>poc.cc: In function ‘int main()’:
poc.cc:15:39: error: array must be initialized with a brace-enclosed initializer
15 | struct conf_t conf = {10,2048,id};
| ^~
</code></pre>
<p>It's true that I could remove the const keyword in the struct and get rid of the stack variable <code>id</code>, where <code>&(conf.id)</code> could be the first parameter of <code>memcpy</code>. However, I'd like to keep the immutability of fields in the conf struct, which enables the compilers to check undesired modifications.</p>
<p>For my understanding, structs in c should have the following memory layout:</p>
<pre><code> 0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| a |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| b |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| |
+ +
| |
+ id +
| |
+ +
| |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
</code></pre>
<p>Given the stack variable <code>id</code> is also with static size, I'm confused why the c++ compiler still looks for a brace-enclosed initializer even if <code>id</code> is already a static-sized array.</p>

74,444,688 | <p>I'm in the process of learning Python, and I'm trying to make a simple loop, for adding dirty prices, to my dataframe bond_df.</p>
<p>Days_left is a Series, bond_df is a pandas dataframe containing the closing prices used in the formula below.</p>
<p><em>If i run the command:</em></p>
<pre><code>days = days_left[1].days
</code></pre>
<p>I get an integer of size 1 with the value of 2, and this is exactly what I need. I need the value of days as integers, and without any other time-stamp on it (see the attached picture). So, I use ".days", so that I can extract the integer value of the days, and get rid of the time-stamp for hours and seconds etc.</p>
<p>Because of this, i figured I could then use this in a loop to construct my column of dirty-prices, in my df:</p>
<pre><code>for i, number in days_left:
days = days_left[i].days
bond_df['dirty_price'][i] = bond_df['closing_price'][i] + ((365 - days)/365)
</code></pre>
<p>However this does not work and returns the message:</p>
<p><em><strong>"TypeError: cannot unpack non-iterable Timedelta object"</strong></em></p>
<p>I then figured, that I could construct a loop using a range instead:</p>
<pre><code>for i in range(0, len(days_left)):
days = days_left[i].days
bond_df['dirty_price'][i] = bond_df['closing_price'][i] + ((365 - days)/365)
print(days, bond_df['dirty_price'])
</code></pre>
<p>This seem to work as intended.</p>
<p>But I would still like to find out, what I did wrong in the first instance.</p>
<p>Can somebody explain the difference between these two loops and why I cannot do as above?</p>
<p><em>All the best,</em>
Nic</p>

74,444,891 | <p>I'm writing C# code that runs Git commands via ProcessStartInfo.</p>
<p>I am aware in terms of syntax that I can run commands from the console in parallel by adding a single <code>&</code> character between them. For example:</p>
<p><code>echo "Hello world!" & echo "Goodbye world!"</code></p>
<p>Because these commands run in parallel they're asynchronous, meaning their output order is random.
The issue is that in my C# code I need to use the response from each command, and unfortunately there is no indicative output to tell me which output belongs to which command I ran.</p>
<p>Is there a way to tell which output came from which command?</p>
<p>For example, a way to echo specific text when the specific command has finished?</p>

74,445,008 | <p>How do I return more than one possible value? (Two sum problem: Determine if any two number inside an array sum to a number A)</p>
<p>I already figure out how to kind of solve the problem.</p>

for i in range(len(arr)):
for j in range(i+1, len(arr)):
if arr[i] + arr[j] == A:
return(arr[i], arr[j])
print(twoSum([1,2,3,4],5))
</code></pre>
<p>However, I only manage to return the first possible value. Although (2, 3) is also correct.</p>
<pre><code>my output: (1, 4)

<p>Is there a way to return multiple values such as</p>

74,445,184 | <p>I received 1 challenge through the interview test.
The requirement of the test is to build a search engine that source data from a txt file, and every time the user enters a word, it will return the results.</p>
<ul>
<li><p>The second requirement is:</p>
<p>Given a single word x, update the search corpus with x. The new word x should immediately be
queryable.</p>
</li>
<li><p>3rd requirement is:</p>
<p>Given a single word y, remove the most similar word to y in the corpus from further search results.</p>
</li>
</ul>
<p>I have never created a search engine before.</p>
<p>How can i create it with NodeJs and what is the meaning of the 2nd and 3rd requirements?</p>
<p>Thanks!</p>

74,445,188 | <p>I configured system and user pool on Azure AKS instances. I follow this guide:</p>
<p><a href="https://learn.microsoft.com/en-us/azure/aks/use-system-pools?tabs=azure-cli#system-and-user-node-pools" rel="nofollow noreferrer">Microrosft Guide</a></p>
<p>before the activity we only had system type pools for applications and system pods as well.</p>
<p>I did the following steps:</p>
<ul>
<li><p>creation of a system type pool and set of the following taint "CriticalAddonsOnly = true: NoSchedule" (to avoid deployment on the system pool for application microservices)</p>
</li>
<li><p>conversion of old pools from system to users</p>
</li>
<li><p>restart the following deployments:</p>
<p>gatekeeper-system:</p>
<ul>
<li>gatekeeper-audit</li>
<li>gatekeeper-controller</li>
</ul>
<p>kube-system:</p>
<ul>
<li>coredns</li>
<li>coredns-autoscaler</li>
<li>metrics-server</li>
<li>azure-policy</li>
<li>azure-policy-webhook</li>
<li>konnectivity-agent</li>
<li>ama-logs-rs</li>
</ul>
</li>
</ul>
<p>to allow the scheduling of system pods also on the pool system since they are not automatically scheduled after pool creation.</p>
<p>Now i'm noticing that the system pods have now been scheduled on the pool system as well but I keep seeing the same pods on all other nodes. Even if I brutally delete them from the user pools, they are immediately redeployed on them. Is the behavior correct? Logically if I have a pool system all pods should only be on that pool and none on the user pool?</p>
<p>Thanks</p>

74,445,207 | <p>I have a problem about getting jwt token from one service and use it in the test method of one service.</p>
<p>I tried to write <strong>JUnit Controller test</strong> in payment, product and order service in my spring boot microservice example. After I defined auth service to handle with creating user and login with <strong>jwt</strong> token and defined api gateway to use <strong>JWTFilter</strong>, it is required to define <strong>bearer token</strong> for each request of each test request method.</p>
<p>Normally, it works but I have to get jwt token and use it but I have no idea how to get it?</p>
<p>Here is an one test method of PaymentControllerTest shown below. As you can see, there is no defination of <strong>Authorization Bearer</strong>. How can I define it?</p>
<pre><code>@Test
@DisplayName("Place Order -- Success Scenario")
void test_When_placeOrder_DoPayment_Success() throws Exception {
OrderRequest orderRequest = getMockOrderRequest();
String jwt = getJWTTokenForRoleUser();
MvcResult mvcResult
= mockMvc.perform(MockMvcRequestBuilders.post("/order/placeorder")
.contentType(MediaType.APPLICATION_JSON_VALUE)
.header("Authorization", "Bearer " + jwt)
.content(objectMapper.writeValueAsString(orderRequest)))
.andExpect(MockMvcResultMatchers.status().isOk())
.andReturn();
String orderId = mvcResult.getResponse().getContentAsString();
Optional<Order> order = orderRepository.findById(Long.valueOf(orderId));
assertTrue(order.isPresent());
Order o = order.get();
assertEquals(Long.parseLong(orderId), o.getId());
assertEquals("PLACED", o.getOrderStatus());
assertEquals(orderRequest.getTotalAmount(), o.getAmount());
assertEquals(orderRequest.getQuantity(), o.getQuantity());
}
</code></pre>
<p>Here are methods regarding the jwt token process</p>
<pre><code>private String getJWTTokenForRoleUser(){
var loginRequest = new LoginRequest("User1","user1");
String jwt = jwtUtils.generateJwtToken(loginRequest.getUsername());
return jwt;
}
@Data
@AllArgsConstructor
@NoArgsConstructor
public class LoginRequest {
private String username;
private String password;
}
</code></pre>
<p>Here is the jwtutil class shown below</p>
<pre><code>@Component
public class JwtUtils {
private static final Logger LOGGER = LoggerFactory.getLogger(JwtUtils.class);
@Value("${jwt.secret}")
private String jwtSecret;
@Value("${jwt.expireMs}")
private int jwtExpirationMs;
public String generateJwtToken(String username) {
return generateTokenFromUsername(username);
}
public String generateTokenFromUsername(String username) {
return Jwts.builder().setSubject(username).setIssuedAt(new Date())
.setExpiration(new Date((new Date()).getTime() + jwtExpirationMs))
.signWith(SignatureAlgorithm.HS512, jwtSecret).compact();
}
}
</code></pre>
<p>To run the app,
<strong>1 )</strong> Run Service Registery (Eureka Server)</p>
<p><strong>2 )</strong> Run config server</p>
<p><strong>3 )</strong> Run zipkin and redis through these commands shown below on docker</p>
<pre><code>docker run -d -p 9411:9411 openzipkin/zipkin
docker run -d --name redis -p 6379:6379 redis
</code></pre>
<p><strong>4 )</strong> Run api gateway</p>
<p><strong>5 )</strong> Run auth service,product service,order service and payment service</p>
<p><strong>Edited</strong> (I defined all properites in application-test.yaml but they couldn't be fetched from OrderControllerTest)</p>
<pre><code>Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'jwt.secret' in value "${jwt.secret}"
</code></pre>
<p>Here is the repo : <a href="https://github.com/Rapter1990/microservicecoursedailybuffer" rel="nofollow noreferrer">Link</a></p>

74,445,264 | <p>This example is from the documentation of HttpUrlConnection:</p>

try {
InputStream in = new BufferedInputStream(urlConnection.getInputStream());

finally {

</code></pre>
<p>The documentation says:</p>
<blockquote>
<p>Once the response body has been read, the HttpURLConnection should be closed by calling disconnect().</p>
</blockquote>
<p>I tried use the Java class to load an image in a functional style:</p>
<pre class="lang-kotlin prettyprint-override"><code>fun fetch (url: String): ImageBitmap =
URL(url)
.openConnection()
.also { it.setRequestProperty (authorization.header, authorization.basicauth()) }
.getInputStream()
.buffered()
.use { BitmapFactory.decodeStream(it) }
.asImageBitmap()
</code></pre>
<p>Now I am wondering how to add the <code>disconnect</code> call?</p>
<p>I want to achieve this:</p>
<pre class="lang-kotlin prettyprint-override"><code>fun fetch (url: String): ImageBitmap {
var connection: HttpURLConnection? = null
return try {
URL(url)
.openConnection()
.also { it.setRequestProperty(authorization.header, authorization.basicauth()) }
.also { connection = it as HttpURLConnection }
.getInputStream()
.buffered()
.use { BitmapFactory.decodeStream(it) }
.asImageBitmap()
} finally {
connection?.disconnect()
}
}

</code></pre>
<p>The above example works. Since boost::typeindex::type_id does not really need the passed variable of type Arg1 (and some types - such as cDog - might not or not easily be dummy-constructable), I thought I could change the implementation to the one below (same template arguments, but no passed parameter pack of those types) and recursively call the template by expanding the pack of <strong>types</strong> instead of the pack of <strong>parameters</strong>. I read <a href="https://en.cppreference.com/w/cpp/language/parameter_pack" rel="nofollow noreferrer">https://en.cppreference.com/w/cpp/language/parameter_pack</a> section "Template argument lists" to mean that this should be possible, but my compiler (vc141) gives me error C2672 (no matching signature found).</p>
<p>edit: The error description apparently has to do with template resolution, but I don't see the applicability to my problem. <a href="https://learn.microsoft.com/en-gb/cpp/error-messages/compiler-errors-2/compiler-error-c2672?view=msvc-150" rel="nofollow noreferrer">https://learn.microsoft.com/en-gb/cpp/error-messages/compiler-errors-2/compiler-error-c2672?view=msvc-150</a></p>
<pre><code>template<typename Arg1, typename... Args>
std::string SignatureToString()
{
std::string strRetVal = boost::typeindex::type_id<Arg1>().pretty_name(); // this line apparently still works (makes sense)
std::string strRemainingSignature = SignatureToString<Args...>(); // expanding type pack does not work (...?)
if (!strRemainingSignature.empty())
{
strRetVal = strRetVal + ", " + strRemainingSignature;
}
return strRetVal;
}
int main(int /*argc*/, char* /*argv*/[])
{
std::cout << "GetSignature(): '" << SignatureToString() << "'" << std::endl;
std::cout << "GetSignature(int): '" << SignatureToString<int>() << "'" << std::endl;
std::cout << "GetSignature(std::string): '" << SignatureToString<std::string>() << "'" << std::endl;
return 0;
}
</code></pre>
<p>What am I doing wrong here?</p>

74,445,333 | <p>I use a timer to count down. I feed seconds into the timer and the countdown begins. The timer works, but the problem is that when I change the page, I get an error that the timer will continue to work. Although I'm already on another page.

<p>How could I drop all rows from <code>df_1</code> in which the same day of <code>df_2</code> has a measurement different from zero? For example, if the first two days of January have 6 and 7 as measurements, I would need to drop all 48 hours of those days in <code>df_1</code>.</p>

74,445,359 | <p>I have a Qml Canvas Item where in, the height of canvas item keeps varying based on the input dynamically. Below is my code</p>
<pre><code>Item {
id: barGraph
property int highestRange: 200
property int rangeVal: (RangeModel.rangeValue === "---") ? highestRange : RangeModel.rangeValue
property int totalHeight: 450
property int canvasHeight: (rangeVal * totalHeight) / highestRange
height: 700
width: 500
x: 120
y: 145
Canvas {
id: mycanvas
height: canvasHeight
width: 16
onPaint: {
var context = getContext("2d");
var startX = mycanvas.x;
var startY = mycanvas.y;
context.lineWidth = 0.5;
context.strokeStyle = "white";
context.beginPath();
context.moveTo(startX, startY);
context.lineTo(startX,(mycanvas.height - 10));
context.lineTo(mycanvas.width, mycanvas.height);
context.lineTo(mycanvas.width, startY + 10);
context.lineTo(mycanvas.width / 2, startY);
context.closePath(); // base drawn automatically
context.fill();
context.stroke();
}
}}
</code></pre>
<p>The output of this code look like this :</p>
<p><a href="https://i.stack.imgur.com/pJDOm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pJDOm.png" alt="canvas with full height" /></a></p>
<p>The problem with this code is, whenever the height of the canvas changes dynamically it actually resizes from the below position as shown in the image</p>
<p><a href="https://i.stack.imgur.com/U07QB.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/U07QB.jpg" alt="resized canvas image" /></a>.</p>
<p>I actually need this to be resized from the Y top position and keeping the below position unmovable which I am unable to achieve through this code.</p>
<p>Any support is much appreciated here.</p>

<p>My real dataframe is almost 200,000 lines long and has 4 different locations and 13 different IDs.</p>
<p>I want to sort these into discrete events (ID at location) with start and end times based on the timestampUTC column, with the events ending at the timestampUTC when the next detection for that ID in that location is more than half an hour later. The next event begins at the next datetime.</p>
<p>Using the example data above, I would want to generate another dataframe that looks something like this:</p>
<pre><code>
ID location event start event end
A69-1601-47272 JB12 2017-10-02 19:23:27 2017-10-02 19:31:46
A69-1601-47272 JB12 2017-10-02 23:52:15 2017-10-02 23:55:13
A69-1601-47272 JB13 2017-10-03 19:53:50 2017-10-03 19:58:26
A69-1601-47280 JB12 2017-10-04 13:15:13 2017-10-04 13:21:39

A69-1601-47280 JB13 2017-10-05 04:55:48 2017-10-05 05:18:40
A69-1601-47280 JB13 2017-10-07 21:24:19 2017-10-07 21:29:25
</code></pre>
<p>If an ID was detected at a location it gives the ID, location, and the start and end of its time there.</p>
<p>For example, you can see that there are 2 discrete events for ID 47272 at location JB12 that occur on the same day (2017-10-02) but the difference between the end of the first event and the start of the second is >30 min (~4 hrs and 20 mins) so they're separate events.</p>
<p>I would add what code I have tried but I don't know where to start with tidyverse and would prefer to do this in python.</p>
<p>Thanks in advance!</p>
<p><strong>And see solution in R here:</strong></p>
<p>Here is an option</p>
<pre><code>
library(tidyverse)
df %>%
mutate(
timestampUTC = as.POSIXct(timestampUTC),
diff = c(0, diff(timestampUTC) / 60),
grp = cumsum(diff > 30)) %>%
group_by(grp) %>%

<p>I've kept some some of the intermediate steps (columns) to help with readability and understanding. In short, we convert timestamps to POSIXct, then calculate time differences in minutes between successive timestamps with diff, create groups of observations based on whether the next timestamp is > 30 minutes away. The rest is grouping by grp and summarising entries from relevant columns.</p>
<p>The same, more succinct (perhaps at the expense of readability)</p>
<pre><code>df %>%
group_by(grp = cumsum(c(0, diff(as.POSIXct(timestampUTC)) / 60) > 30)) %>%
summarise(
ID = first(ID),
location = first(location),
`event start` = first(timestampUTC),
`event end` = last(timestampUTC)) %>%
select(-grp)

74,445,430 | <p>First, I want to capture pose values by subscribing to teleop_key from a turtle. Then I want to change these captured values and publish to a second turtle. The problem is that I couldn't capture the pose values as a global variables. And due to this I couldn't change the variables and published the modified ones.</p>
<p>I think I have an almost finished code. That's why I'm going to throw them all out directly.</p>
<pre><code>#!/usr/bin/env python3
from turtlesim.msg import Pose
from geometry_msgs.msg import Twist
import rospy as rp
global pos_l_x,pos_l_y,pos_l_z,pos_a_x,pos_a_y,pos_a_z
def pose_callback(msg):
rp.loginfo("("+ str(msg.x) + "," + str(msg.y) + "," + str(msg.theta)+ ")")
pos_l_x = msg.x
pos_l_y = msg.y
pos_a_z = msg.theta
if __name__ == '__main__':
rp.init_node("turtle_inverse")
while not rp.is_shutdown():
sub = rp.Subscriber("/turtlesim1/turtle1/pose", Pose, callback= pose_callback)
rate = rp.Rate(1)
rp.loginfo("Node has been started")
cmd = Twist()
cmd.linear.x = -1*pos_l_x
cmd.linear.y = -1*pos_l_y
cmd.linear.z = 0
cmd.angular.x = 0
cmd.angular.y = 0
cmd.angular.z = -1*pos_a_z
pub = rp.Publisher("/turtlesim2/turtle1/cmd_vel", Twist, queue_size=10)
try:
pub.publish(cmd)
except rp.ServiceException as e:
rp.logwarn(e)
rate.sleep()
rp.spin()
</code></pre>
<p>And I did the connection between turtle1 and turtle2 in the lunch file below:</p>
<pre><code><?xml version="1.0"?>
<launch>
<group ns="turtlesim1">
<node pkg="turtlesim" type="turtlesim_node" name="turtle1">
<remap from="/turtle1/cmd_vel" to="vel_1"/>
</node>
<node pkg="turtlesim" type="turtle_teleop_key" name="Joyistic" output= "screen">
<remap from="/turtle1/cmd_vel" to="vel_1"/>
</node>
</group>
<group ns="turtlesim2">
<node pkg="turtlesim" type="turtlesim_node" name="turtle1">
</node>
</group>
<node pkg="turtlesim" type="mimic" name="mimic">
<remap from="input" to="turtlesim1/turtle1"/>
<remap from="output" to="turtlesim2/turtle1"/>
</node>
</launch>
</code></pre>
<p>And lastly here my package.xml code:</p>
<pre><code><?xml version="1.0"?>

74,445,489 | <p>I am currently learning Laravel. I had a pre-built script and I need to do some changes in it to make it usable... But as much I learnt from the web, I understood that the routes are specified in the Routes/web.php file.
But in the application I'm working on, the routes are defined in Routes/api.php file.</p>
<p>I even tried to find out the HTML pages in the Views folder but it only has the code for the tables which are there on the User Interface. All the controllers also return some data (like... return $data) in the end but no php or blade.php file is mentioned in any controller.</p>
<p>I need to find out the HTML pages so that I can change some components or elements from that website.</p>
<p>Please help me with this. Thanks!</p>

74,445,527 | <p><strong>Problem</strong>
Compute a per-warp histogram of sorted sequence of numbers held by individual threads in a warp.</p>
<p>Example:</p>
<pre><code>lane: 0123456789... 31
val: 222244455777799999 ..
</code></pre>
<p>The result must be held by N lower threads in a warp (where N is the amount of unique numbers), e.g.:</p>
<pre><code>lane 0: val=2, num=4 (2 occurs 4 times)
lane 1: val=4, num=3 (4 occurs 3 times)
lane 2: val=5, num=2 ...
lane 3: val=7, num=4
lane 4: val=9, num=5
...
</code></pre>
<p>Note that, it is essentially not required for a sequence of 'val' to be sorted: it's only necessary for equal numbers to be grouped together, i.e.: 99955555773333333...</p>
<p><strong>Possible solution</strong>
This can be done quite efficiently with shuffle intrinsics,
though my question is whether it's possible to do this <em>without</em> using shared memory at all (I mean shared memory is a scarce resource, I need it somewhere else) ?</p>
<p>For simplicity, I execute this code for a single warp only (so that printf works fine):</p>
<pre><code>__device__ __inline__ void sorted_seq_histogram()
{
uint32_t tid = threadIdx.x, lane = tid % 32;
uint32_t val = (lane + 117)* 23 / 97; // sorted sequence of values to be reduced
printf("%d: val = %d\n", lane, val);
uint32_t num = 1;
uint32_t allmsk = 0xffffffffu, shfl_c = 31;
for(int i = 1; i <= 16; i *= 2) {
#if 1
uint32_t xval = __shfl_down_sync(allmsk, val, i),
xnum = __shfl_down_sync(allmsk, num, i);
if(lane + i < 32) {
if(val == xval)
num += xnum;
}
#else // this is a (hopefully) optimized version of the code above
asm(R"({
.reg .u32 r0,r1;
.reg .pred p;
shfl.sync.down.b32 r0|p, %1, %2, %3, %4;
shfl.sync.down.b32 r1|p, %0, %2, %3, %4;
@p setp.eq.s32 p, %1, r0;
@p add.u32 r1, r1, %0;
@p mov.u32 %0, r1;
})"
: "+r"(num) : "r"(val), "r"(i), "r"(shfl_c), "r"(allmsk));
#endif
}
// shfl.sync wraps around: so thread 0 gets the value of thread 31
bool leader = val != __shfl_sync(allmsk, val, lane - 1);
auto OK = __ballot_sync(allmsk, leader); // find delimiter threads
auto total = __popc(OK); // the total number of unique numbers found
auto lanelt = (1 << lane) - 1;
auto idx = __popc(OK & lanelt);
printf("%d: val = %d; num = %d; total: %d; idx = %d; leader: %d\n", lane, val, num, total, idx, leader);
__shared__ uint32_t sh[64];
if(leader) { // here we need shared memory :(
sh[idx] = val;
sh[idx + 32] = num;
}
__syncthreads();
if(lane < total) {
val = sh[lane], num = sh[lane + 32];
} else {
val = 0xDEADBABE, num = 0;
}
printf("%d: final val = %d; num = %d\n", lane, val, num);

74,445,571 | <p>Im trying to setup a planning for 20 employees and 2 years.
In here I want to hide the weeks that already passed in the input.</p>
<p>Down below is how far I got. After testing it seems to work till the "All" part but can't figure the last part out. With the inputbox I want that the person is able to enter the value based on the first row, 2023 week 1 (20231) till 2024 week 52 (202452).</p>
<p>My goal is that if someone enters the value of 202336 it should show 2023 week 36 and later and it hides the previous weeks.</p>
<p>Is someone able to help me? Thanks in advance!</p>
<pre><code>Sub Hidepastweeks()
Dim myValue As Variant
myValue = InputBox("Weeks visible from week:", "Visable weeks")
Dim c As Range
Range("A2").Value = myValue
With Range("G1:DF1")
Application.ScreenUpdating = False
.EntireColumn.Hidden = (myValue <> "All")
If myValue <> "All" Then
For Each c In Range("G1:DF1").Cells
If c.Value < "myValue" Then
c.EntireColumn.Hidden = True
End If
Next
End If
Application.ScreenUpdating = True
End With
End Sub
</code></pre>
<p>I Tried different sites but they all seem to have an equal to formula instead of lesser then.</p>

74,445,620 | <p>I am working on a legacy application with a class named <code>Point3D</code> as shown below...</p>
<pre><code>template <class T>
class Point3D final
{
T values[3];
public:
Point3D();
Point3D(T x, T y, T z);
explicit Point3D(const T value);
Point3D(const Point3D& point);
explicit Point3D(const Point2D<T>& point);
~Point3D();
};
</code></pre>
<p>This class is getting used in many places as <code>vector<Point3D<double>></code>. The size of the vector is > <code>10^5</code>.
Also, the legacy code passes this vector as a value and returns by value. This is making the application very slow.
Also in many places, we have similar codes as shown below...</p>
<pre><code>for(auto i: n){ // This loop runs for 10^4 times
Point3D<double> vpos;
vpos[X_COORDINATE] = /*Some calculation*/;
vpos[Y_COORDINATE] = /*Some calculation*/;
vpos[Z_COORDINATE] = /*Some calculation*/;
Positions.push_back(vpos);
}
</code></pre>
<p>To improve the performance, I plan to modify the <code>Point3D</code> class to use <code>move semantics</code> as shown below...</p>
<pre><code>template <class T>
class Point3D final {
T* values;
public:
Point3D() {
values = new T[3];
}
Point3D(T x, T y, T z) {
values = new T[3];
}
explicit Point3D(const T value) {
values = new T[3];
}
Point3D(const Point3D& point) {
values = new T[3];
}
~Point3D() {
delete[] values;
}
T operator [] (qint64 coordinate) const { return values[coordinate]; }
T& operator [] (qint64 coordinate) { return values[coordinate]; }
Point3D& operator = (const Point3D& point) {
...
return *this;
}
Point3D(Point3D&& other) noexcept : values(other.values)
{
other.values = nullptr;
}
Point3D& operator=(Point3D&& other) noexcept
{
using std::swap;
swap(*this, other);
return *this;
}
};
</code></pre>
<p>I am new to <code>move semantics</code>, please let me know any other ways to improve the performance.
Thanks</p>

74,445,635 | <p>I've recently inherited some code. It has a class called <code>SystemConfig</code> that acts as a grab-bag of constants that are used across the code base. But while a few of the constants are defined directly on that class, a big pile of them are defined as properties of a metaclass of that class. Like this:</p>
<pre><code>class _MetaSystemConfig(type):
@property
define CONSTANT_1(cls):
return "value 1"
@property
define CONSTANT_2(cls):
return "value 2"
...
class SystemConfig(metaclass=_MetaSystemConfig):
CONSTANT_3 = "value 3"
...
</code></pre>
<p>The class is never instantiated; the values are just used as <code>SystemConfig.CONSTANT_1</code> and so on.</p>
<p>No-one who is still involved in the project seems to have any idea why it was done this way, except that someone seems to think the guy who did it thought it made unit testing easier.</p>
<p>Can someone explain to me any advantages of doing it this way and why I shouldn't just move all the properties to the <code>SystemConfig</code> class and delete the metaclass?</p>
<p>Edit to add: The metaclass definition doesn't contain anything other than properties.</p>

74,445,638 | <p>I need to solve a maze using backtracking method.
My maze has 0 listed as a wall, 1 listed as an empty cell, 2 is for visited, 3 for dragon.
Dragons are basically obstacles that I can go through BUT I need to choose the path with the LEAST dragons.
So far I can solve the maze and mark a path, but I can't seem to think of a relatively simple way of finding the path with the least dragons.
Do note we just started coding with C in my uni (so far I've only done java/bash/a bit of python), so I'm really new to C and algorithms in general.</p>
<p>Code is below.</p>
<pre><code>#include <stdio.h>
#define IMPOSSIBLE (N*N+1)
int counter=0;
enum {WALL,EMPTY,VISITED,DRAGON,N};
int printMaze(int maze[N][N])
{
for (int i = 0; i < N; ++i) {
for (int j = 0; j < N; ++j) {
printf("%d ",maze[i][j]);
}
printf("\n");
}
}
int solveMaze(int maze[N][N], int i, int j)
{
if (maze[i][j] == WALL){ return 0; } // If [i][j] are currently a wall (0).
if (maze[i][j] == VISITED) { return 0; } // If [i][j] are currently a mark (2).
if (maze[i][j] == DRAGON) { counter++; }
maze[i][j] = VISITED; // Mark current spot with (2).
if (i==N-1 && j==N-1) { return 1; } // reached the end (N-1,N-1) - (3,3) incase N is 4.
if ( ((i < N-1) && solveMaze(maze,i+1,j)) || ((i > 0) && solveMaze(maze,i-1,j)) || ((j < N-1) && solveMaze(maze,i,j+1)) || ((j > 0) && solveMaze(maze,i,j-1)) ) { // checking index-out-bounds + recursively going around the maze
return 1;
}
maze[i][j] = EMPTY;
return 0;
}
int main() {
int maze[N][N] = { {1,1,3,3},
{3,0,1,1},
{3,0,0,1},
{1,3,3,1} };
int solved = solveMaze(maze, 0, 0);
if (solved)
{
printMaze(maze);
printf("Amount of dragons passed through in the maze: %d\n",counter);
}
else
{
printf("No solution, %d\n",IMPOSSIBLE);
}
}
</code></pre>
<p>I tried creating a counter that counts the amount of dragons on the way, but I guess I'm not fluent enough in recursions to make it go in every available path and choose the best one.</p>

74,445,827 | <p>I am making a video player using pygame, it takes numpy arrays of frames from a video file and streams them to a pygame window using a buffer.</p>
<p>I'm getting a weird issue where CPU usage is increasing <em>(program is slowing down)</em> over time, then CPU usage is sharply decreasing <em>(program is speeding up)</em>. Memory usage stays pretty much constant, so I don't think it's a memory leak. This affects the program as I'm trying to stream a video, and long processing times turn it into a slideshow.</p>
<p>I would expect fluctuations, but not that steep. I cannot seem to figure what is going on here, I would really appreciate some help in debugging this!</p>
<hr />
<p>Source code to replicate the issue at the end of the question. You can use any
.mp4 file, but the exact one I used is <a href="https://drive.google.com/file/d/1_tfTVHmaoTEYxkLrjVS8NiAvdes3Gd77/view?usp=share_link" rel="nofollow noreferrer">here to download</a>. This
also outputs a log.txt file which I am using to debug the issue. My findings are below...</p>
<hr />
<p><strong>In the first few seconds, process time is relatively fast:</strong></p>
<pre><code>[12:13:31] (Variable: current_frame) 1
[12:13:31] (Variable: len(frame_buffer)) 3
[12:13:31] (Process time) 0.08 seconds
</code></pre>
<p><strong>It steadily slows over the duration of about 30 seconds, until it hits peak slowness at ~0.5 seconds of process time:</strong></p>
<pre><code>[12:14:07] (Variable: current_frame) 154
[12:14:07] (Variable: len(frame_buffer)) 3
[12:14:07] (Process time) 0.53 seconds
</code></pre>
<p><strong>Then it dips down to previous levels:</strong></p>
<pre><code>[12:14:11] (Variable: current_frame) 164
[12:14:11] (Variable: len(frame_buffer)) 3
[12:14:11] (Process time) 0.1 seconds
</code></pre>
<p>Here is a graph I made using matplotlib to identify the trend over ~1000 frames:

74,445,921 | <p>For this vectorial function I want to evaluate the jacobian:</p>
<pre><code>import jax
import jax.numpy as jnp
def myf(arr, phi_0, phi_1, phi_2, lambda_0, R):
arr = jnp.deg2rad(arr)
phi_0 = jnp.deg2rad(phi_0)
phi_1 = jnp.deg2rad(phi_1)
phi_2 = jnp.deg2rad(phi_2)
lambda_0 = jnp.deg2rad(lambda_0)
n = jnp.sin(phi_1)
F = 2.0
rho_0 = 1.0
rho = R*F*(1/jnp.tan(jnp.pi/4 + arr[1]/2))**n
x_L = rho*jnp.sin(n*(arr[0] - lambda_0))
y_L = rho_0 - rho*jnp.cos(n*(arr[0] - lambda_0))
return jnp.array([x_L,y_L])
arr = jnp.array([-18.1, 29.9])
jax.jacobian(myf)(arr, 29.5, 29.5, 29.5, -17.0, R=1)
</code></pre>
<p>I obtain</p>
<pre><code>[[ 0.01312758 0.00014317]
[-0.00012411 0.01514319]]
</code></pre>
<p>I'm in shock with these values. Take for instance the element <code>[0][0], 0.01312758</code>. We know it's the partial of <code>x_L</code> with respect to the variable <code>arr[0]</code>. Whether by hand or using sympy that derivative is ~0.75.</p>
<pre><code>from sympy import *
x, y = symbols('x y')
x_L = (2.0*(1/tan(3.141592/4 + y/2))**0.492)*sin(0.492*(x + 0.2967))
deriv = Derivative(x_L, x)
deriv.doit()
deriv.doit().evalf(subs={x: -0.3159, y: 0.52})
0.752473089673695
</code></pre>
<p>(inserting <code>x, y</code>, that are <code>arr[0]</code> and <code>arr[1]</code> already in radians). This is also the result I obtain by hand. What is happening with Jax results? I can't see what I'm doing bad.</p>

74,445,936 | <p>I am running a Kafka Cluster Docker Compose on an AWS EC2 instance.

But I also want to count the most used words of those tweets.</p>

<p>When I check the output topic in the Control Center, it looks like this:</p>
<p><a href="https://i.stack.imgur.com/1Z2l5.png" rel="nofollow noreferrer">Key</a></p>
<p><a href="https://i.stack.imgur.com/9co4b.png" rel="nofollow noreferrer">Value</a></p>
<p>Looks like it's working as far as splitting the tweets into single words. But the count value isn't in Long format, although it is specified in the code.</p>
<p>When I use the kafka-console-consumer to consume from this topic, it says:</p>
<p>"Size of data received by LongDeserializer is not 8"</p>

74,445,959 | <p>I'm having a child component that get some data from a form. And passes that to a parent component via the @Output decorator. Pressing a button triggers getDataFromForm()</p>
<pre><code>export class FormChildComponent {
@Output() doSomethingWithData: EventEmitter<any> = new EventEmitter<any>()
...
getDataFromForm(){
...
this.doSomethingWithData.emit(form.values);
}
renderSomething(?data){
//This needs to be called in anther child after the event got
triggered and the data got processed in the parent
}
}
</code></pre>
<p>In the parent component I'm doing some processing with the data, on the button press event in the child. After that I have to render something based on the processed data in another child, which is the same child component type as above.</p>
<p>parent.component.html</p>
<pre><code><FormChildComponent (doSomethingWithData)="processData($event)">
</code></pre>
<p>parent.component.ts</p>
<pre><code>processData($event: object){
doSomething($event);
}
</code></pre>
<p>What's the best practice to pass events and data between children and their parent?</p>
