<p>I was expecting the elements of the queue to be printed.
When the line
"struct queue *q;"
is replaced with this "
*struct queue *q=(struct queue *)malloc(sizeof(struct queue));"
it works, what is the reason?</p>

74,414,215 | <p>In my code I have a number of places where I need to take an std::vector of things and put it into a std::map indexed by something. For example here are two code snippets:</p>
<pre><code>//sample A
std::map<Mode::Type, std::vector<Mode>> modesByType;
for( const auto& mode : _modes ) {
Mode::Type type = mode.getType();
auto it = modesByType.find( type );
if( it == modesByType.end() ) {
std::vector<Mode> v = { mode };
modesByType.insert( std::pair( type, v ) );
} else {
it->second.push_back( mode );
}
}
//sample B
std::map<unsigned, std::vector<Category>> categoriesByTab;
for( const auto& category : _categories ) {
unsigned tabIndex = category.getTab();
auto it = categoriesByTab.find( tabIndex );
if( it == categoriesByTab.end() ) {
std::vector<Category> v = { category };
categoriesByTab.insert( std::pair( tabIndex, v ) );
} else {
it->second.push_back( category );
}
}
</code></pre>
<p>I'd like to generalize this and create a template function like:</p>
<pre><code>template<typename T, typename V>
std::map<T,std::vector<V>> getMapByType( const std::vector<V>& items, ?? ) {
std::map<T,std::vector<V>> itemsByType;
for( const auto& item : items ) {
unsigned index = ??;
auto it = itemsByType.find( index );
if( it == itemsByType.end() ) {
std::vector<V> v = { item };
itemsByType.insert( std::pair( index, v ) );
} else {
it->second.push_back( item );
}
}
return itemsByType;
}
</code></pre>
<p>My question is, how do I define the ?? argument to this function so that I can call the correct V.foo() function to get the index value for the map?</p>
<p>Note, I do not want to make all the classes that this template (V) accepts, inherit from a base class. Can I somehow specify a lambda argument?</p>

74,414,232 | <p>I don't know how to rename columns that are unnamed.
I have tried both approaches where I am putting the indices in quoutes and not, like this, and it didn't work:</p>
<pre><code> train_dataset_with_pred_new_df.rename(columns={
0 : 'timestamp', 1 : 'open', 2 : 'close', 3 : 'high', 4 : 'low', 5 : 'volume', 6 : 'CCI7', 7 : 'DI+',\
8 : 'DI-', 9 : 'ADX', 10 : 'MACD Main', 11 : 'MACD Signal', 12 : 'MACD histogram', 13 : 'Fisher Transform',\
14 : 'Fisher Trigger'
})
</code></pre>
<p>And</p>
<pre><code> train_dataset_with_pred_new_df.rename(columns={
'0' : 'timestamp', '1' : 'open', '2' : 'close', '3' : 'high', '4' : 'low', '5' : 'volume', '6' : 'CCI7', '8' : 'DI+',\
'9' : 'DI-', '10' : 'ADX', '11' : 'MACD Main', '12' : 'MACD Signal', '13' : 'MACD histogram', '15' : 'Fisher Transform',\
'16' : 'Fisher Trigger'
})
</code></pre>
<p>So If both didn't worked, how do I rename them?</p>
<p>Thank you for your help in advance :)</p>

74,414,248 | <p>I am running sql query in python, I have a requirement to dynamically generate dates and append it to my sql query.This script runs on every Monday. If the week of Monday falls between two months then I have to restrict the date range till last of the previous month (i.e 30th or 31st). Any Ideas on how to achieve this ?</p>
<p>I tried to get the weeknumber and their respective dates but I couldn't find the exact function which will return me list of dates with corresponding week number</p>

However, if the Text of the class "dropdown-name" is bigger than 4em it isn't perfectly aligned to the right side anymore.</li>
<li>I also tried using the left, right, top and bottom CSS, but that doesn't work, because the dropdown-content is absolutely positioned, so it just gets completely messed up.</li>
</ul>
<h1>What I need:</h1>
<p>A "Simple" way of shifting the content the exact amount to the left it goes off screen.
It would be best if the solution only includes CSS, or if it's impossible, then JavaScript. <strong>No jQuery</strong>, the Rest of my code works without it.</p>
<p>PS: The CSS is just a portion of all the 340 Lines of CSS, here it only contains the most Relevant.</p>
<p>PPS: The text inside the button elements is just for testing purposes.</p>
<p>PPPS: Where do I add Code Snippets? There's no button for it. There's only "Link, Blockquote, Code Block, Image, Table". There's no 6th button... am I missing something?</p>

74,414,272 | <p><code>aes_string</code> had some convenient behaviours that I made use of when programming with ggplot2. But <code>aes_string</code> has been deprecated (noticeably since ggplot2 version 3.4.0 I believe). I am struggling with how to nicely replace it.</p>
<p>Specifically, I previously created functions that accepted arbitrary string arguments through the ellipsis, and passed these to aes_string via do.call, as shown in the first reprex below.</p>
<p>Since noticing the deprecation warning I have tried to avoid <code>aes_string</code>, and found myself effectively just mimicking it in a rather "hacky" looking way.
Presumably, whatever flaw in <code>aes_string</code> led to its deprecation, would also apply to my hacky workaround. See the second reprex.</p>
<p><strong>Is there a more elegant solution? I want to continue passing the variable names as strings.</strong></p>

<p>I'd like to project this polar plot over an arbitrary lon/lat... I can convert the polar theta/phi into lon/lat, but lon/lat coords (used on the map) are more 'cartesian like' than polar, hence you cannot just substitute lon/lat for theta/phi ... This is a conceptual problem. How would you tackle it?</p>

74,414,314 | <p>I'm using .NET exclusively for Entity Framework's elegant handling of migrations. I have a working project with an EF schema. The part I now need is to move the DB connection string into configuration.</p>
<p>All I have so far is the following:</p>
<pre><code>public partial class EfContext : DbContext

{
if (!optionsBuilder.IsConfigured)
{
optionsBuilder.UseNpgsql("Host=localhost;Port=5432;Database=...;Username=...;Password=...");
}
}
}

<p>There is no other code apart from the entity definitions and migrations (no Startup class or HostBuilder stuff at all).</p>
<p>Can any kind soul instruct me in the simplest way to move the string into <code>appSettings.<env>.json</code>?</p>

74,414,349 | <p>How can I retrain only 2 decimals for each values in a Pandas series? (I'm working with latitudes and longitudes). dtype is float64.</p>
<pre><code>series = [-74.002568, -74.003085, -74.003546]
</code></pre>
<p>I tried using the round function but as the name suggests, it rounds. I looked into trunc() but this can only remove all decimals. Then I figures why not try running a For loop. I tried the following:</p>
<pre><code>for i in series:
i = "{0:.2f}".format(i)
</code></pre>
<p>I was able to run the code without any errors but it didn't modify the data in any way.</p>
<p>Expected output would be the following:</p>
<pre><code>[-74.00, -74.00, -74.00]
</code></pre>
<p>Anyone knows how to achieve this? Thanks!</p>

74,414,366 | <p>I have a situation in a piece of dynamic programming where i either want to get the pre computed results, or call a function to compute these results.</p>
<p>This is the situation in short</p>
<pre><code>let previous_results HashMap<String, Result> = HashMap::new();
for i in some_values {
let result = previous_results.get(i).unwrap_or_else(|| calculate_results(i))
}
</code></pre>
<p>The rust compiler justly complains about the function call and it says</p>
<pre><code>expected reference `&HashMap<std::string::String, Result>`
found struct `HashMap<std::string::String, Result>`
</code></pre>
<p>This is because <code>.get</code> normally returns a reference to the object,and not the actual object, but the function returns an actual object. So i could just return a reference to what the function returns</p>
<pre><code>let result = previous_results.get(i).unwrap_or_else(|| &calculate_results(i))
</code></pre>
<p>Note the <code>&</code>in front of the function call. But this is also an issue, cause a reference to something that is scoped within the anonymous function will be meaningless as soon as the anonymous function returns. And rust complains</p>
<pre><code>cannot return reference to temporary value
returns a reference to data owned by the current function
</code></pre>
<p>What am i missing here? What is the correct approach to do this in rust?</p>

74,414,426 | <p>I have a file named default.xex that is located in XBLA_Unpacked/DirectoryName/Subdirectory/000D0000/default.xex.
I am trying to rename default.xex to be DirectoryName.xex. I managed to accomplish this with File.Move() but it pulled the .xex file up into XBLA_Unpacked, so both DirectoryName and DirectoryName.xex are located there. I need to be able to rename the .xex file while also keeping it inside the 000D000 subdirectory.</p>
<p>This is my current code which renames the .xex file and moves it up to the XBLA_Unpacked directory, as well as the code I wrote to try to move it back after it was renamed that doesn't work.</p>
<pre><code> static void ReNamePirs()
{
string homePath = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);
string unpackedPath = homePath + "\\XBLA_Unpacked\\";
string reNamePath = homePath + "\\XBLA_Unpacked";
var files = GetAllFiles(unpackedPath);
var folders = GetAllFolders(unpackedPath);
List<string> sourceName = Directory.GetFiles(unpackedPath, "default.xex", SearchOption.AllDirectories).ToList();
List<string> destinationName = Directory.GetDirectories(unpackedPath, "*", SearchOption.TopDirectoryOnly).ToList();
List<string> finalDestination = Directory.GetDirectories(unpackedPath, "000D0000", SearchOption.AllDirectories).ToList();
for (int i = 0; i < sourceName.Count; i++)
{
destinationName[i] = destinationName[i] + ".xex";
File.Move(sourceName[i], destinationName[i]);
}
sourceName = Directory.GetFiles(reNamePath, ".xex", SearchOption.AllDirectories).ToList();
for (int i = 0; i < sourceName.Count; i++)
{
destinationName = Directory.GetDirectories(unpackedPath, "000D0000", SearchOption.AllDirectories).ToList();

74,414,674 | <h3>A problem description:</h3>
<p>I have two strings and I need to find the length of intersection of them.</p>
<p><em>Let's assume the both strings are Latin-ASCII and lower case.</em></p>
<p>These are expected results:</p>
<pre><code>$str1 = "lorem ipsum";
$str2 = "rem";
echo str_intersection($str1, $str2); // Expected result: 3
$str2 = "xzy";
echo str_intersection($str1, $str2); // Expected result: 0
</code></pre>
<hr />
<h3>My try to solve the problem:</h3>
<p>I've tried to compare the strings using <code>array_intersect()</code> function this way:</p>
<pre><code>$str_intersection = function(string $str1, string $str2): int {
$arr1 = str_split($str1); // ['l','o','r','e','m',' ','i','p','s','u','m']
$arr2 = str_split($str2); // ['r','e','m']
return count(array_intersect($arr1, $arr2));
};
echo $str_intersection($str1, $str2); // Result: 4 (because of lo*REM* ipsu*M*)
</code></pre>
<p>But this way of comparing two strings is inappropriate because it compares occurrences of characters and not whole parts of strings as I need it.</p>
<p>In addition, the str_intersection() function designed in this way is not only inappropriate, but also very slow if I need to compare thousands of strings.</p>
<hr />
<h3>Example how I plan to use the needed function:</h3>
<p>As requested I wrote a little example how I plan to use the string intersection function:</p>
<pre><code>$strings = ['lorem', 'ipsum', 'dolor', 'sit', 'amet', 'consectetur'];
$needle = 'lo';
$intersections = [];
foreach ($strings as $str) {
$intersections[] = str_intersection($str, $needle);
}
print_r($intersections);
</code></pre>
<p>Expected result (intersection "<em>highlighed</em>" as uppercase):</p>
<pre><code>Array (
[0] => 1 // LOrem
[1] => 0 // ipsum
[2] => 1 // doLOr
[3] => 0 // sit
[4] => 0 // amet
[5] => 0 // consectetur
)

74,414,731 | <p>I merged a pull request in bit bucket from a feature branch into master and now I want to update my local copy of master. I've tried git fetch, git pull, git reset --hard, git reset --hard origin/master. I was expecting my local master branch to be updated with the new commits, but it was not. I am getting the message already up to date, and no changes are applied to my local copy. Any suggestions are appreciated.</p>
<p>--update</p>
<pre><code>git status
On branch master
Your branch is up to date with 'origin/master'.
Untracked files:
(use "git add <file>..." to include in what will be committed)
application/config/audio/
nothing added to commit but untracked files present (use "git add" to track)
--
git pull
Already up to date

<p>As you can see, it's JavaScript and has functions. But I need a way of parsing the rest of the object as JSON, <strong>without using eval</strong>.</p>
<p>It can either return <code>null</code> where there were functions or completely remove the key and value.</p>
<p>I have tried the following RegEx but I'm not the best at it so I just keep messing up the object to make it unparsable and unrunnable.</p>
<pre class="lang-js prettyprint-override"><code>/function\([^()]*\){[^}]*}/gi
</code></pre>
<p>Which then replaces with <code>null</code></p>

74,414,825 | <p><strong>What does program solve:</strong><br />
Find palindrome from user input.</p>
<p><strong>What issue to tweak:</strong><br />
How to make code accept sentence like <code>Rise to vote sir!</code> as Palindrome if we disregard punctuation and blank spaces. If you read it backwards it will be the same!</p>
<p><strong>Things that I have tried:</strong>
I tried to just save characters a-z, A-Z, and 0-9 into character-type array then proceed with the logic on it. But to no avail.</p>
<p>I wish if <strong>someone</strong> could suggest where to tweak the following C snippet, in a way it can handle phrase or sentence to not include spaces, punctuation, and special characters within the computation of the code logic.</p>
<pre><code>/* Search for a palindrome */
#include <stdio.h>
#include <ctype.h>
#define EOL '\n'
#define TRUE 1
#define FALSE 0
int main()
{
int tag, count, countback, flag, loop = TRUE;
char letter[80];
/* main loop */
while (loop)
{
/* anticipated palindrome */
flag = TRUE;
/* read in the text */
printf("\nPlease enter a word, phrase, or sentence below:\n");
for (count = 0; (letter[count] = getchar()) != EOL; ++count)
;
/* test for end of program keyword END */
if ((toupper(letter[0]) == 'E') && \
(toupper(letter[1]) == 'N') && \
(toupper(letter[2]) == 'D'))
break;
tag = count - 1;
/* carry out the search */
for ((count = 0, countback = tag); count <= tag / 2; (++count, --countback))
{
if (letter[count] != letter[countback])
{
flag = FALSE;
break;
}
}
/* display message */
for (count = 0; count <= tag; ++count)
putchar(letter[count]);
if (flag)
printf(" --> IS a Palindrome!\n\n");
else
printf(" --> is NOT a Palindrome.\n\n");
} /* end of main loop */
return 0;

74,414,838 | <p>Does anyone know how to move through one file to the other if they are in the same directory?</p>
<p>Example: in file "A.txt" is written the name of the next file, meaning "B.txt," then in "B.txt", is written the name of the next file - "C.txt," and the content of "C.txt" is "A.txt," forming the chain "A.txt"-"B.txt"-"C.txt". BUT, there might be any N amount of files, not only 3.</p>
<p>I tried looping through the files, although I couldn't do anything with it.I have never worked with chaining files and their contests so i am completely lost,even one small advice would be appreciated.</p>

<p>I set a complete by <code>complete -W 'AA BB' -I</code>, It worked "after a command delimiter"</p>
<pre><code>root@aliecs:~# complete -W 'AA BB' -I
root@aliecs:~# ls &&<tab><tab>
AA BB
root@aliecs:~# ls ;<tab><tab>
AA BB
root@aliecs:~# ls |<tab><tab>
AA BB
root@aliecs:~# ls ||<tab><tab>
AA BB
</code></pre>
<p>I want an example of "the initial non-assignment word on the line"</p>

74,414,914 | <p>I have a file that looks like this:</p>
<pre class="lang-none prettyprint-override"><code>1234:AnneShirly:anneshirley@seneca.ca:4:5\[SRT111,OPS105,OPS110,SPR100,ENG100\]

<p>I want to be able to ask the user for an input(the student number at the beginning of each line) and then ask which course they want to delete(the course codes are the list). So the program would delete the course from the list in the student number without deleting other instances of the course. Cause other students have the same courses.</p>
<pre><code>studentid = input("enter studentid")
course = input("enter the course to delete")
with open("studentDatabase.dat") as file:
f = file.readlines()
with open("studentDatabase.dat","w") as file:
for line in lines:
if line.find(course) == -1:
file.write(line)
</code></pre>
<p>This just deletes the whole line but I only want to delete the course</p>

74,414,936 | <p>I want to write a program where a user tells me an integer(n) and i calculate The sum of 1+(1-2)+(1-2+3)+(1-2+3-n)... where even integers are -k and odd integers are +k.</p>
<p>Ive made a function which does that But the sum is never correct. For example for n=2 it should be sum=0 but shows sum=-1 for n=3 should be sum=+2 but i shows sum=3. (Ignore the debugging printfs)</p>
<pre><code>#include <stdio.h>
int athroismaAkolouthias(int n); // i sinartisi me tin opoia ypologizete to athroisma akolouthias 1+(1-2)+(1-2+3)+(1-2+3-4).....

int n;
printf("give n: ");
scanf("%d", &n);
printf("the sum is %d", athroismaAkolouthias(n));
}
int athroismaAkolouthias(int n){
int sum1=0, sum2=0,sum=0;
int i, temp, j;

74,414,944 | <p>I have two problems that are giving me issues. First issue:</p>
<pre><code>import requests
import json
name = 'Poe'
poem = 'Raven'
URL = f'https://poetrydb.org/author,title/{name};{poem}'
json_object = json.loads(requests.get(URL).text)
text=str(json_object)
with open("choice_1.json", "w") as outfile:
outfile.write(json_object)
</code></pre>
<p>running the code gives me:
TypeError: write() argument must be str, not list</p>
<p>this is a json object going into a json file, what is the problem?</p>
<p>second problem</p>
<p>I want the saved file to read the same as the poem's name. how do I get the 'poem' variable to used for naming the new file? something like a print function:</p>
<pre><code>with open("{poem}.json", "w") as outfile:
outfile.write(json_object)
</code></pre>
<p>problem 1 I tried converting the json files into a string with str() but it still didn't work.</p>
<pre><code>URL = f'https://poetrydb.org/author,title/{name};{poem}'
json_object = json.loads(requests.get(URL).text)
text=str(json_object)
with open("choice_1.json", "w") as outfile:
outfile.write(text)
</code></pre>
<p>while this creates the file it comes out like this:
[{'title': 'The Raven', 'author': 'Edgar Allan Poe', 'lines': ['Once upon a midnight dreary, while I</p>
<p>it's all red and underlined like there is an issue. does this actually work?</p>

74,414,951 | <p>I have a large dataset where I have a problem similar to the one below. I have something like this:</p>
<pre><code>dummydf <- data.frame(country = c("USA", "USA"),
state = c("Oregon", "California"),
name = c("anne", "paul"),
family = c("stevens", "williams"),
votes = c(10, 50.2),
city = c("london", "berlin"),
age = c(10, 50),
`name...2` = c("joseph", "vincent"),
`family...2` = c("ramos", "williams"),
`votes...2` = c(15, 62),
`city...2` = c("lisbon", "berlin"),
`age...2` = c(77, 43),
`name...3` = c("johanna", "paul"),
`family...3` = c("santos", "ramos"),
`votes...3` = c(.61, 54.2),
`city...3` = c("london", "berlin"),
`age...3` = c(56, 54),
`name...4` = c("sara", "edith"),
`family...4` = c("stevens", "sanchez"),
`votes...4` = c(2.9, 54.1),
`city...4` = c("lisbon", "paris"),
`age...4` = c(20, 25),
`name...5` = c("thomas", "paul"),
`family...5` = c("santos", "ramos"),
`votes...5` = c(1.2, 5.2),
`city...5` = c("lisbon", "toronto"),
`age...5` = c(45, 80))
</code></pre>
<p>or maybe this is easier to understand:</p>
<pre><code>country state name family votes city age name...2 family...2 votes...2 city...2 age...2 name...3 family...3 votes...3 city...3 age...3 name...4 family...4 votes...4
1 USA Oregon anne stevens 10.0 london 10 joseph ramos 15 lisbon 77 johanna santos 0.61 london 56 sara stevens 2.9
2 USA California paul williams 50.2 berlin 50 vincent williams 62 berlin 43 paul ramos 54.20 berlin 54 edith sanchez 54.1
city...4 age...4 name...5 family...5 votes...5 city...5 age...5
1 lisbon 20 thomas santos 1.2 lisbon 45
2 paris 25 paul ramos 5.2 toronto 80
</code></pre>
<p>So the issue here is that all the columns except <code>country</code> and <code>state</code> are multipled 5 times. Ideally I want something like this:</p>
<pre><code>idealdf
name family votes city age state country
1 anne stevens 10.00 london 10 Oregon USA
2 paul williams 50.20 berlin 50 California USA
3 joseph ramos 15.00 lisbon 77 Oregon USA
4 vincent williams 62.00 berlin 43 California USA
5 johanna santos 0.61 london 56 Oregon USA
6 paul ramos 54.20 berlin 54 California USA
7 sara stevens 2.90 lisbon 20 Oregon USA
8 edith sanchez 54.10 paris 25 California USA
9 thomas santos 1.20 lisbon 45 Oregon USA
10 paul ramos 5.20 toronto 80 California USA
</code></pre>
<p>In the original dataset I have it multiple several hundred times and not 5 but the issue is the same. I tried a few things with pivoting and trying to clean the names with regular expressions but nothing really works well. Any pointers would be amazing - thanks!</p>

1 take input for list length
2 take input of list
3 search in list for the values from zero to last index increment the counter.

74,414,995 | <p>Example is here, should work in online compilers:</p>
<pre class="lang-cs prettyprint-override"><code>internal class Program
{
static void Main(string[] args)
{
var i1 = new Item();
i1.Val1 = 1;
i1.Val2 = 2.1;

{
list.OrderBy(x => x.Val2); //list will be ordered, but not saved

}
}
public class Item
{
public int Val1 { get; set; }
public double Val2 { get; set; }

</code></pre>
<p>It's simplified code of what I'm trying to do - I need to order list inside <code>Func</code>, but I have no idea how. First line works in theory, but since it's not a void it's not working in practice - list is not actually ordered.</p>
<p>Second line should work, actually Visual Studio suggested that, but it throws runtime exception - <code>Unable to cast object of type System.Linq.OrderedEnumerable to System.Linq.IGrouping</code>.</p>
<p>I'm out of ideas for the time being, but there is no way of bypassing it - I absolutely need to order it there.</p>
<p>Edit</p>
<p>My current solution is to use <code>Select(x => x)</code> to flatten the <code>IGrouping</code> to normal <code>List</code>, this way I can easily order it and edit values without losing reference to <code>grouped</code>. If you really want to keep <code>IGrouping</code> then you are out of luck, does not seem to be possible.</p>

74,415,044 | <p>i am experimenting with a multi-column magazine style layout for an editorial project.</p>
<p>Due to the increasing size of the monitors, i wanted to use of all available inches of the monitor by creating layouts very similar to paper magazine (two or three columns per page).</p>
<p>I am using TipTap editor for article management (as it returns very clean HTML code) and in frontend i get this html output:</p>
<p><a href="https://i.stack.imgur.com/peD2T.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/peD2T.png" alt="enter image description here" /></a></p>
<p>I am using the css columns class to split the article in two:</p>
<pre><code> article {
columns: 2;
}
</code></pre>
<p>But the result is this:
<a href="https://i.stack.imgur.com/DWJac.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DWJac.png" alt="enter image description here" /></a></p>
<p>I would like to divide all the <strong>h2</strong> as settling paragraphs, so that i could have the chapter exploded horizontally, for example like this:
<a href="https://i.stack.imgur.com/EAX1Y.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EAX1Y.jpg" alt="enter image description here" /></a></p>
<p>Using Pseudo-classes is it possible to intercept H2?</p>

74,415,058 | <p>I would like to produce histograms with density lines for all my numeric columns, and facet them by another column.</p>
<p>Using the <a href="https://en.wikipedia.org/wiki/Iris_flower_data_set" rel="nofollow noreferrer">Iris data set</a> as an example, I would like to produce histograms for <code>Sepal.Length</code>, etc., with facets for each of <code>Species</code>.</p>
<p>This is what I have tried:</p>
<pre><code>for (i in colnames(subset(iris, select = -`Species`))) {
plot= ggplot(iris, aes(x= i))+
geom_histogram()+
geom_density(colour = "blue", size = 1) +
facet_wrap(~ Species, scales = "free")
print(plot)
}
</code></pre>
<p>I also tried</p>
<pre><code>for (i in colnames(subset(iris, select = -`Species`))) {
plot= ggplot(subset(iris, select = -`Species`), aes(x= i))+
geom_histogram()+
geom_density(colour = "blue", size = 1) +
facet_wrap(~ iris$Species, scales = "free")
print(plot)
}
</code></pre>
<p>The error I get is</p>
<blockquote>
<p>Error in <code>f()</code>:
StatBin requires a continuous x variable: the x variable is discrete. Perhaps you want stat="count"?</p>
</blockquote>
<p>Do I need to put something in the <code>geom_histogram()</code> command?</p>

x = Solution()
x.min_of_two()

74,415,166 | <p>You are given a string my_string and a positive integer k. Write code that prints the first substring of my_string of length k all of whose characters are identical (lowercase and uppercase are different). If none such exists, print an appropriate error message (see Example 4 below). In particular, the latter holds when my_string is empty.</p>
<p>Example: For the input my_string = “abaadddefggg”, k = 3 the output is For length 3, found the substring ddd!
Example: For the input my_string = “abaadddefggg”, k = 9 the output is Didn't find a substring of length 9</p>
<p>this is my attempt:</p>
<pre><code>my_string = 'abaadddefggg'
k = 3
s=''
for i in range(len(my_string) - k + 1):
if my_string[i:i+k] == my_string[i] * k:
s = my_string[i:i+k]

RateLimiter::for('api', function (Request $request) {
return Limit::perMinute(60)->by($request->user()?->id ?: $request->ip());

</code></pre>
<p>According to my understanding it will limit the rate attempts to 60 by minute by either user id or IP address if there is not user logged in, Am I correct?</p>
<p>But then how will the ternary translates to a classical if sequence? something like this?</p>
<pre><code>if (null !== $request->user()) {
$request->user()->id;
} else {
$request->ip();
}
</code></pre>
<p>Its the first time i see a ternary used in this way, can you give me some more examples of this use?</p>

74,415,181 | <p>My custom blazor component uses an external script (hosted on a CDN). Usually one would reference it in <code>index.html</code>, but I don't want to do that - I want the component to be self contained and easy to use.</p>
<p>The typical solution is a script loader. A popular implementation has been floating around for years: <a href="https://stackoverflow.com/a/58979941/9971404">here</a> and <a href="https://www.geekinsta.com/add-javascript-in-blazor-components/" rel="nofollow noreferrer">here</a>.</p>
<p><code>wwwroot/js/scriptLoader.js</code> (referenced in <code>index.html</code>):</p>
<pre class="lang-js prettyprint-override"><code>let _loadedScripts = []; // list of loading / loaded scripts
export async function loadScript(src) {
// only load script once
if (_loadedScripts[src])
return Promise.resolve();
return new Promise(function(resolve, reject) {
let tag = document.createElement('script');
tag.type = 'text/javascript';
tag.src = src;
// mark script as loading/loaded
_loadedScripts[src] = true;
tag.onload = function() {
resolve();
}
tag.onerror = function() {
console.error('Failed to load script.');
reject(src);
}
document.body.appendChild(tag);
});
}
</code></pre>
<p>Then I create a component where I want to load a custom script.</p>
<p><code>FooComponent.razor</code>:</p>
<pre class="lang-cs prettyprint-override"><code>@inject IJSRuntime _js
// etc...
protected override async Task OnAfterRenderAsync(bool firstRender)
{
await base.OnAfterRenderAsync(firstRender);
if (firstRender)
{
// load component's script (using script loader)
await _js.InvokeVoidAsync("loadScript", "https://cdn.example.com/foo.min.js");
}
// invoke `doFoo()` from 'foo.min.js' script
await _js.InvokeVoidAsync("doFoo", "hello world!");
}
</code></pre>
<p>That works. I can use the <code><FooComponent /></code> and it will load its own script file.</p>
<p>But if I use the component multiple times, I run into a race condition:</p>
<ul>
<li>instance 1 of the component
<ul>
<li>tries to load the script</li>
<li>script loader loads the script</li>
<li>the component can use it</li>
</ul>
</li>
<li>instances 2+ of the component
<ul>
<li>they are loading at the same time as instance 1!</li>
<li>each tries to load the script, but the loader refuses to load it more than once</li>
<li>they immediately try to use the script - but it's still busy loading!</li>
<li>so they all fail and the app crashes (exceptions, etc.)</li>
</ul>
</li>
</ul>
<p>How can I refactor the code to ensure that the script is actually finished loading, before using it?</p>

74,415,207 | <p>I have some sort of poll where you vote either YES and NO and based on the votes it creates a poll chart (by creating two divs inside another div that has a set width and setting the width of the first two divs the percentage of YES and NO votes out of the total votes). You can see the project for a better understanding by clicking <a href="https://jsfiddle.net/2yhrsf8m/" rel="nofollow noreferrer">HERE</a>.</p>
<p>I want it to appear animated as if it were in CSS with <code>transition: width 100ms linear;</code> just like here:</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-html lang-html prettyprint-override"><code><!DOCTYPE html>
<html>
<head>
<title>Document</title>
<style>
.poll{
height: 50px;
width: 300px;
background-color: black;
transition: all 300ms;
}
.poll:hover{
width: 500px;
}
</style>
</head>
<body>
<div class="poll"></div>
</body>
</html></code></pre>
</div>
</div>
</p>
<p>However, whenever I add something similar to the class of my divs I see no change. The divs in question are created in this function:</p>
<pre><code>function renderPoll(){
container.innerHTML=''; //reset container
let poll1 = document.createElement('div');
let poll2 = document.createElement('div');
poll1.classList.add('poll-attr');
poll2.classList.add('poll-attr');
let innerTextPoll = Math.round(calcPerc()); //calcPerc() calculates the percent of YES votes with the equation percentage = (100*NumberOfYES)/NumberOfVotes
poll1.style.width = calcPerc() + '%';
poll2.style.width = 100-calcPerc() + '%';
poll1.innerText = innerTextPoll + '%';
poll2.innerText = 100-innerTextPoll + '%';
container.appendChild(poll1);
container.appendChild(poll2);
</code></pre>
<p>}</p>
<p>I am not nearly experienced enough to figure this out so any input is appreciated!</p>

74,415,386 | <p>I am writing a program in which I add students to a roster using linked lists. I am successful at adding the first student, but upon adding subsequent students, my program prints "Student already exists" even when the student doesn't exist yet. Below is my add function.</p>
<pre><code>struct student *add(struct student *list){
struct student *p;
struct student *new_student = malloc(sizeof(struct student));
printf("Enter the student's last name: ");
read_line(new_student->last, NAME_LEN);
printf("Enter the student's first name: ");
read_line(new_student->first, NAME_LEN);
printf("Enter the student's email: ");
read_line(new_student->email, EMAIL_LEN);
printf("Enter the student's instrument: ");
read_line(new_student->instrument, INSTRUMENT_LEN);
printf("Enter the student's group name: ");
read_line(new_student->group, GROUP_LEN);
if(new_student == NULL){
printf("\nMalloc failed.\n");
return list;
}
if(list==NULL){
return new_student;
}
for(p=list;p!=NULL; p=p->next){
if((strcmp(p->first,new_student->first)==0) &&
(strcmp(p->last, new_student->last)==0)){
printf("\nThis student already exists.\n");
return list;
}
else{
while(p->next==NULL){
p->next = new_student;
new_student->next = NULL;
printf("\nStudent has been added to the roster.\n");
break; //FOR LOOP NOT BREAKING?
}
}
}
return new_student;
}
</code></pre>
<p>If anyone can help me understand how to fix this so that the for loop doesn't keep executing after the student is added to the list, I'd appreciate it.</p>
<p>It doesn't seem as though my break statement is working. I've tried making the return to new_student occur within my else statement, but that causes other issues in my program. Any help is appreciated.</p>

<p>I would like if you guys could try to not use a different thing like arrays to print a value. Please use the while loop unless I <strong>need</strong> to change the way I am doing this.</p>
<p>If you would like, you can use methods, but I prefer not to in this scenario. I do not think a method is necessary right now. Share your feedback.</p>

74,415,476 | <p>I'm new on the OCR world and I have document with numbers to analyse with Python, openCV and pytesserract.
The files I received are pdfs and the numbers are not text. So, I converted it to jpg with this :</p>
<pre><code>first_page = convert_from_path(path__to_pdf, dpi=600, first_page=1, last_page=1)
first_page[0].save(TEMP_FOLDER+'temp.jpg', 'JPEG')
</code></pre>
<p>Then , the images look like this :
I still have some noise around the digits.</p>
<p><a href="https://i.stack.imgur.com/a5PI3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/a5PI3.png" alt="enter image description here" /></a></p>
<p>I tried to select the "black color only" with this :</p>
<pre><code>img_hsv = cv2.cvtColor(img_raw, cv2.COLOR_BGR2HSV)
img_changing = cv2.cvtColor(img_raw, cv2.COLOR_RGB2GRAY)
low_color = np.array([0, 0, 0])
high_color = np.array([180, 255, 30])
blackColorMask = cv2.inRange(img_hsv, low_color, high_color)
img_inversion = cv2.bitwise_not(img_changing)
img_black_filtered = cv2.bitwise_and(img_inversion, img_inversion, mask = blackColorMask)
img_final_inversion = cv2.bitwise_not(img_black_filtered)
</code></pre>
<p>So, with this code, my image looks like this :
<a href="https://i.stack.imgur.com/8js13.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8js13.jpg" alt="enter image description here" /></a></p>
<p>Even with cv2.blur, I don't even reach 75% of image FULLY analysed.
For at least 25% of the images, pytesseract misses 1 or more digits.
Is that normal ? Do you have ideas of what I can do to maximize the succesfull rate ?</p>
<p>Thanks</p>

74,415,536 | <p>In the leading DeepLearning libraries, does the filter (aka kernel or weight) in the convolutional layer convolves also across the "channel" dimension or does it take all the channels at once?
To make an example, if the input dimension is <code>(60,60,10)</code> (where the last dimension is often referred as "channels") and the desired output number of channels is 5, can the filter be <code>(5,5,5,5)</code> or should it be <code>(5,5,10,5)</code> instead ?</p>

74,415,578 | <p>Hello <strong>Stack OF</strong> Community,</p>
<p>*<br />
Basically my goal is to extract values from an excel file, after reading through data from another column.*</p>
<p>**<br />
Thickness** of parcel, with values for example - <strong>[0.12, 0.12, 0.13, 0.14, 0.14, 0.15]</strong> (Heading: Thickness (mm))<br />
<strong>Weight</strong> of parcel, with values for example - <strong>[4.000, 3.500, 2.500, 4.500, 5.000, 2.000]</strong> (Heading: Weight (KG))</p>
<p>Excel File:<br />
<strong>Thickness</strong> <strong>Weight</strong><br />
0.12 4.000<br />
0.12 3.500<br />
0.13 2.500<br />
0.14 4.500<br />
0.14 5.000<br />
0.15 2.000</p>
<p>Looking to generate this using <strong>Python</strong>:<br />
Thickness Weight Parcels<br />
0.12 7.500 2 Parcels<br />
0.13 2.500 1 Parcels<br />
0.14 9.500 2 Parcels<br />
0.15 2.000 1 Parcels</p>
<p>TOTAL: 21.500 6 Parcels</p>
<p>The user will be shown all the current values of <strong>Thickness Available</strong> and will be allowed to <strong>input</strong> a <em>single thickness value to get its weight</em> or <em>a range and get its weight</em>.</p>
<p>So anyone of you who can recommend me how can this task be accomplished easily and efficiently.</p>
<p>I would be very grateful for your advice.</p>
<p><em>Please note: I have only done Python Programming Language.</em></p>
<p>Thank You.</p>
<p>I have learned Openpyxl but also got to know that Pandas is an efficent tool for Data Analysis, so please let me know!</p>
<p>Arigato!</p>

74,415,582 | <p>I have address of an struct store in int variable. Can I dereference the struct??</p>
<p>say: int x = 3432234; // memory address of struct
now I want to access the some struct from it.</p>
<p>I have been suggest these steps.</p>
<ol>
<li>store the address in an int variable</li>
<li>cast that int to a struct pointer</li>
<li>then dereference it</li>
</ol>
<p>But don't know how to apply.</p>

74,415,597 | <p>I'm trying to use curl to set up a cron to reboot my WD N900 Router on a regular basis.</p>
<p>Using Chrome's developer tools, when I login to the the router via its WebGUI, it brings me to "authentication.cgi". Here's its essential components copied as a curl (bash):</p>
<pre><code>curl 'http://192.168.1.1/authentication.cgi' \
-H 'Cookie: QPYVIXOAZD=admin; uid=lseKLfq8zc' \
--data-raw 'USERNAME=admin&DIGEST=XXXXXXXXXXXXXXXXXXX'
</code></pre>
<p>The critical component is the cookie entry, of which the uid is unique for that particular login.</p>
<p>To reboot the router, I then go through several pages, eventually getting to "service.cgi". Here's its essential components copied as a curl (bash):</p>
<pre><code>curl 'http://192.168.1.1/service.cgi' \
-H 'Cookie: QPYVIXOAZD=admin; uid=lseKLfq8zc' \
--data-raw 'EVENT=REBOOT'
</code></pre>
<p>For a successful reboot via curl from service.cgi, the cookie uid must be the same as that in authentication.cgi. Otherwise, it doesn't reboot, and states "Authorization failure."</p>
<p>How can I get this to work without first obtaining a cookie via a WebGUI login (which defeats the purpose of curl)?</p>
<p>I tried to set up a cookie jar (curl -c /tmp/cookie-jar.txt ....) and remove the "Cookie:..." line, which resulted in another "Authorization failure" as well as an empty cookie file save for this:</p>
<pre><code># Netscape HTTP Cookie File
# https://curl.se/docs/http-cookies.html
# This file was generated by libcurl! Edit at your own risk.
</code></pre>
<p>I also tried "curl - u myusername:mypassword" (with and without --digest or --noauth options) to no avail ("authorization failure").</p>
<p>Any suggestions are greatly appreciated.</p>
<hr />
<p><strong>UPDATE:</strong> When I curl authentication.cgi with my username:password:</p>
<pre><code>curl --user admin:XXXXXXXXXX 'http://192.168.1.1/authentication.cgi'
</code></pre>
<p>I get this type of response:</p>
<pre><code>{"uid": "9auO5hcbq8", "CHALLENGE": "bdce6395-f46b-4306-a61b-1ec2de1bf7d5"}
</code></pre>
<p>Can this information be used somehow? I pasted that uid into the Cookie in my previous curl for service.cgi, but no luck.</p>

74,415,598 | <h3>My problem</h3>
<p>I have 2 <strong>adjacent</strong> buffers of bytes of identical size (around 20 MB each). I just want to count the differences between them.</p>
<h3>My question</h3>
<p>How much time this loop should take to run on a 4.8GHz Intel I7 9700K with 3600MT RAM ?</p>
<p>How do we compute max theoretical speed ?</p>
<h3>What I tried</h3>
<pre class="lang-c++ prettyprint-override"><code>uint64_t compareFunction(const char *const __restrict buffer, const uint64_t commonSize)
{
uint64_t diffFound = 0;
for(uint64_t byte = 0; byte < commonSize; ++byte)
diffFound += static_cast<uint64_t>(buffer[byte] != buffer[byte + commonSize]);
return diffFound;
}
</code></pre>
<p>It takes 11ms on my PC (9700K 4.8Ghz RAM 3600 Windows 10 Clang 14.0.6 -O3 MinGW ) and I feel it is too slow and that I am missing something.</p>
<p>40MB should take less than 2ms to be read on the CPU (my RAM bandwidth is between 20 and 30GB/s)</p>
<p><strong>I don't know how to count cycles required to execute one iteration</strong> (especially because CPUs are superscalar nowadays). If I assume 1 cycle per operation and if I don't mess up my counting, it should be 10 ops per iteration -> 200 million ops -> at 4.8 Ghz with only one execution unit -> 40ms. Obviously I am wrong on how to compute the number of cycles per loop.</p>
<p>Fun fact: I tried on Linux PopOS GCC 11.2 -O3 and it ran at 4.5ms. Why such a difference?</p>
<p>Here are the dissassemblies vectorised and scalar produced by clang:</p>

74,415,616 | <p>I'm trying to refresh the authentication token every few minutes using a refresh token. My problem is that the token is saved in a <code>Context</code> (using <code>useContext</code> to retrieve it when necessary) and I'm struggling to use a <code>setInterval</code>-like function to read the current token, POST it to the server and renew it in the state.</p>
<p>This is what I'm trying to do:</p>
<pre><code> const {
tryLocalSignIn,
signin,
signout,
state: AuthState,
} = useContext(AuthContext);
...
let id = setInterval(async () => {
let token = AuthState.token;
let refreshToken = AuthState.refreshToken;
console.log("Running refresh token", token, refreshToken);
let answer = await ApiRefreshToken(token, refreshToken);
if (answer.status !== 200) {
setError("Error using refresh token");
return;
}
signin({
token: answer.data.token,
refreshToken: answer.data.refreshToken,
expires_in: answer.data.expires_in,
});
}, 15000);
...
</code></pre>
<p>But I'm unable to read from the AuthState</p>

74,415,629 | <p>I'm trying to implement the <code>ls</code> command in C with a few parameters like <code>-a</code>, <code>-l</code>... or <code>-la</code>, but I'm having issues with the parsing, when I use the input I get Segmentation Fault, this is an example of the <code>-a</code> parameter:</p>
<pre><code>int comparator(char *av) {
int i = 0;
if (my_strcmp((av[i]), "-a") == 0)
return 0;
else
return 1;
}
int my_ls_a(char *path) {
int comp = comparator(path);
DIR *pdirec = opendir(".");
struct dirent *direc;
direc = readdir(pdirec);
while (direc != NULL || comp == 0) {
my_printf("%s ", direc->d_name);
direc = readdir(pdirec);
}
if ((path = readdir(pdirec)) == NULL)
my_printf("\n");
if (pdirec == NULL)
return (84);
closedir(pdirec);
return (0);
}
</code></pre>
<p>And this is my main:</p>
<pre><code>int main(int ac, char *av[]) {
if (ac == 1)
my_ls_a(av[0]);
return 0;
}
</code></pre>
<p>I already have all the <code>#include</code> in a .h by the way.</p>
<p>When I only use the <code>main</code> function it works but not when I add the parameter <code>-a</code>.</p>

74,415,634 | <p>I created a class called Cards and I need to create a function called <code>points(self)</code> which returns that card and its associated points. For example the I have three lists I created,</p>
<pre><code>Card_rank = ["2", "3", "4", "5", "6", "Q", "J", "K", "7", "A"]
Cardsuit = ["H", "C", "S", "D"]
points2 = ["0", "2", "3", "4", "10", "11"]
</code></pre>
<p>and when the function is called if the input in self is either "2" - "6" + any value from card suit it will print the card with value from <code>Card_rank</code> and <code>Cardsuit</code> and will give 0 points from <code>points2</code> list.</p>
<p>I have tried this:</p>
<pre><code>def points(self):
if self[0] == "2":
print(self + " Card points is " + self.points2[0])
</code></pre>

<h1>A place I Enjoyed visiting</h1>
<h2 class="sec-h2">Cape Greco, Cyprus</h2>
<p>Cape Greco is cape and also a small peninsula in the southeast of Cyprus, in Famagusta, between Ayia Napa and Paralimni.
According to the findings of the excavations that took place in 1992, this site is considered to be one of the most ancient settlements on the island
</p>
<p>
In the sea area of Cape Greco there are submarine ravines and caves that are popular for diving.
Within sea ravines up to 10 meters high, there are sea caves, which are called "palaces".
These caves, along with Smugglers caves, are accessible only by the sea.

74,415,648 | <p>I have query:</p>
<pre><code>SELECT
(SELECT employee_title FROM sf_employee WHERE id = T1.worker_ref_id) AS employee_title,
(SELECT sex FROM sf_employee WHERE id = T1.worker_ref_id) AS sex,
((SELECT salary FROM sf_employee WHERE id = T1.worker_ref_id) + bonus_sum) as sum_plus_bonus
FROM
(SELECT worker_ref_id, SUM(bonus) as bonus_sum
FROM sf_bonus
GROUP BY worker_ref_id) AS T1
</code></pre>
<p>and the only way I know how to do the grouping is to make this table a subquery in the T2 table in FROM and then group and find the average value for the first and second columns by salary with bonuses:</p>
<pre><code>SELECT employee_title, sex, AVG(sum_plus_bonus) AS avg_salary
FROM
(SELECT
(SELECT employee_title FROM sf_employee WHERE id = T1.worker_ref_id) AS employee_title,
(SELECT sex FROM sf_employee WHERE id = T1.worker_ref_id) AS sex,
((SELECT salary FROM sf_employee WHERE id = T1.worker_ref_id) + bonus_sum) as sum_plus_bonus
FROM
(SELECT worker_ref_id, SUM(bonus) as bonus_sum
FROM sf_bonus
GROUP BY worker_ref_id) AS T1) AS T2
GROUP BY employee_title, sex
</code></pre>
<p>It works, but I have no experience, so it looks a bit strange to me, I think I can do without adding code as in the second option.
I am not interested in JOINs and some other functions, I am training subqueries to be confident in using them, if anyone is interested in the task, here it is:

74,415,658 | <p>I've started learning <code>numpy</code> since yesterday.</p>
<p><strong>my AIM is</strong></p>
<p>Extract <code>odd index</code> elements from numpy array & <code>even index</code> elements from numpy and merge side by side vertically.</p>
<p>Let's say I have the array</p>
<pre><code>mat = np.array([[1, 1, 0, 0, 0],
[0, 1, 0, 0, 1],
[1, 0, 0, 1, 1],
[0, 0, 0, 0, 0],
[1, 0, 1, 0, 1]])

<p><a href="https://i.stack.imgur.com/XTsI2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XTsI2.png" alt="see this picture" /></a></p>
<p>What I've tried.</p>
<p>-->I've done transposing as I've to merge side by by side vertically.</p>
<p><code>mat = np.transpose(mat)</code></p>
<p>Which gives me</p>
<pre><code>[[1 0 1 0 1]
[1 1 0 0 0]
[0 0 0 0 1]
[0 0 1 0 0]
[0 1 1 0 1]]
</code></pre>
<p>I've tried accessing odd index elements</p>
<p><code>odd = mat[1::2] print(odd)</code></p>
<p>Gives me</p>
<p><code>[[1 1 0 0 0]</code> ----> wrong...should be <code>[0,1,0,0,1]</code> right? I'm confused</p>
<p><code>[0 0 1 0 0]]</code> --->wrong...Should be <code>[0,0,0,0,0]</code> right? Where these are coming from?</p>
<p>My final output should like like</p>
<pre><code>[[0 0 1 1 1]
[1 0 1 0 0]
[0 0 0 0 1]
[0 0 0 1 0]
[1 0 0 1 1]]

74,415,661 | <p>I have a MATLAB application that reads a .bin file and parses through the data. I am trying to convert this script from MATLAB to Python but am seeing discrepancies in the values being read.</p>
<p>The read function utilized in the MATLAB script is:</p>
<pre class="lang-matlab prettyprint-override"><code>fname = 'file.bin';
f=fopen(fname);
data = fread(f, 100);
fclose(f);
</code></pre>
<p>The Python conversion I attempted is: (<strong>edited</strong>)</p>
<pre class="lang-py prettyprint-override"><code>fname = 'file.bin'
with open(fname, mode='rb') as f:
data= list(f.read(100))
</code></pre>
<p>I would then print a side-by-side comparison of the read bytes with their index and found discrepancies between the two. I have confirmed that the values read in Python are correct by executing <code>$ hexdump -n 100 -C file.bin</code> and by viewing the file's contents on the application HexEdit.</p>
<p>I would appreciate any insight into the source of discrepancies between the two programs and how I may be able to resolve it.</p>
<p>Note: I am trying to only utilize built-in Python libraries to resolve this issue.</p>
<p><strong>Solution</strong>: Utilizing incorrect file path/structure between programming languages. Implementing @juanpa.arrivillaga's suggestion cleanly reproduced the MATLAB results.</p>

name = ""
for i in b:
if b.index(i) + 1 <= len(b) - 1:
if i in "き / キ" and b[b.index(i) + 1] in "ゃ ャ":
if b[b.index(i) + 1] != " ":
del b[b.index(i) + 1]
del b[int(b.index(i))]
cur = "kya"
name += cur
print(name)
</code></pre>
<p>but it always automatically giving an index 0 to "き", so i can't check it more than once.
How can i change that?</p>
<p>I tried to delete an element after analyzing it.... but it didn't help.</p>

74,415,857 | <p>I'm trying to learn Node.js and I'm currently making an Express app (using ejs) that will return values from a <strong>MySQL database</strong>, depending on the URL the user visits.</p>
<p>For example, visiting <code>http://localhost:3000/test</code> will list all users from the db table <code>users</code>. And the link <code>http://localhost:3000/test/3</code> will return information about the user with the id number 3.</p>
<p>My code for: <strong>/test</strong></p>
<pre><code>app.get("/test", (req, res) => {
let sql = "SELECT * FROM users ORDER BY name";
db.query(sql, function (err, results, fields) {
if (err)
logmessage(err.message);
res.render("test", { data: results });
});
});
</code></pre>
<p>And here is the code for <strong>/test/:id</strong></p>
<pre><code>app.get("/test/:id", (req, res) => {
var userId = req.params.id;
let sql = "SELECT * FROM users WHERE id = " + userId;
db.query(sql, function (err, results, fields) {
if (err || !results.length) {
res.redirect("/");
} else {
res.render("test_user", { data: results });
}
});
});
</code></pre>
<p>My question is: is this safe? When I previously worked in PHP development, I used to prepare statements before making any queries.</p>
<p>What happens if a user changes the URL from: <code>http://localhost:3000/test/3</code> and inserts some SQL injection code at the end of the url? Can the database be breached?</p>
<p>This will be for a live app on the web, so it's important no SQL injection can be made. I also want to add a form later on (req.body instead of req.params) that I also need to sanitize.</p>
<p>Or is there a built-in "prepared statement" already in Node?</p>

74,415,859 | <p>I was searching in the net about connection between STM32 microcontroller and AWS IoT core, didnt come across any. I cam across articles where the discovery board of STM32 is used to connect to AWS IoT core. But I want a simple way to connect the STM32 microcontroller to AWS IoT core with the help of WiFi module (since STM32 microcontroller boards dont usually have WiFi modules)</p>
<p>I tried searching as I have already told but didnt come any resources related to what I was searching. I was specifically looking for resources related to STM32F1 series.</p>

74,415,900 | <p>I have a pretty basic problem that I can't seem to solve:</p>
<p>Take 3 vectors:</p>
<div class="s-table-container">

<td>5</td>
<td>8</td>

<tr>
<td>3</td>
<td>6</td>

</tbody>
</table>
</div>
<p>I want to merge the 3 columns into a single column and assign a group.</p>
<p>Desired result:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Group</th>
<th>Value</th>
</tr>
</thead>
<tbody>
<tr>
<td>A</td>
<td>1</td>

<tr>

<tr>
<td>A</td>
<td>3</td>

<tr>

<tr>

</tr>
<tr>
<td>C</td>
<td>7</td>
</tr>
<tr>
<td>C</td>
<td>8</td>
</tr>
<tr>
<td>C</td>
<td>9</td>
</tr>
</tbody>
</table>
</div>
<p>My code:</p>
<pre><code>V1 <- c(1,2,3)
V2 <- c(4,5,6)
V3 <- c(7,8,9)
data <- data.frame(group = c("A", "B", "C"),

<p>How can I reshape the data to get the desired result?</p>

</code></pre>
<p>But I had no luck when I put it into another page with the partial tag helper:</p>
<pre><code><partial name="_Address" model="Model.Address" />
</code></pre>
<p>Now I understand why this technique doesn't work - that partial views are just for making HTML and don't get processed by the model binder on the way back.</p>
<p>But I would prefer not to copy and paste forms all over my site. Is there any better way to reuse commonly used form bits like this?</p>

74,415,916 | <p>My goal is to import a table of astrophysical data that I have saved to my computer (obtained from matching 2 other tables in TOPCAT, if you know it), and extract certain relevant columns. I hope to then do further manipulations on these columns. I am a complete beginner in python, so I apologise for basic errors. I've done my best to try and solve my problem on my own but I'm a bit lost.</p>
<p>This script I have written so far:</p>
<pre><code>import pandas as pd
input_file = "location\\filename"
dataset = pd.read_csv(input_file,skiprows=12,usecols=[1])
</code></pre>
<p>The file that I'm trying to import is listed as having file type "File", in my drive. I've looked at this file in Notepad and it has a lot of descriptive bumf in the first few rows, so to try and get rid of this I've used "skiprows" as you can see. The data in the file is separated column-wise by lines--at least that's how it appears in Notepad.</p>
<p>The problem is when I try to extract the first column using "usecol" it instead returns what appears to be the first row in the command window, as well as a load of vertical bars between each value. I assume it is somehow not interpreting the table correctly? Not understanding what's a column and what's a row.</p>
<p><strong>What I've tried:</strong> Modifying the file and saving it in a different filetype. This gives the following error:</p>
<pre><code>FileNotFoundError: \[Errno 2\] No such file or directory: 'location\\filename'
</code></pre>
<p>Despite the fact that the new file is saved in exactly the same location.</p>
<p>I've tried using "pd.read_table" instead of csv, but this doesn't seem to change anything (nor does it give me an error).</p>
<p>When I've tried to extract multiple columns (ie "usecol=[1,2]") I get the following error:</p>
<pre><code>ValueError: Usecols do not match columns, columns expected but not found: \[1, 2\]
</code></pre>
<p>My hope is that someone with experience can give some insight into what's likely going on to cause these problems.</p>

74,415,918 | <p>I have two inputs</p>
<p>An NxM city grid where empty spaces represent vacant lots, and X's represent filled lots</p>
<p>e.g</p>
<pre><code>X XXX
X X
XXXX
XX X
</code></pre>
<p>This is in the format List[List[str]]</p>
<p>And an integer that represents the number of buildings required.</p>
<p>Return a list of all possible placements, i.e. List[List[List[str]]]</p>
<p>for example, a possible result using the map above and number of buildings required = 3</p>
<pre><code>XBXXX
BXB X
XXXX
XX X
</code></pre>
<p>another would be</p>
<pre><code>X XXX
X X
XXXXB
BXXBX
</code></pre>
<p>If the number of buildings required > vacant lot count, return an appropriate error</p>
<p>I've tried backtracking. Below is my attempt at a solution, but the 'current_city_map' can't keep track of the state one level up, as in when the 'find_permutations' returns when building_count = 0, the current city map still has the maximum building count already on it</p>
<pre><code>
`def can_place_building(xPos, yPos, city_map, building_code):
return city_map[yPos][xPos] == ' ':
def find_permutations(initial_city_map, current_city_map, building_code, required_building_count, possible_combinations):
if required_building_count == 0:
possible_combinations.append(current_city_map)
return
for x in range(len(current_city_map[0])):
for y in range(len(current_city_map)):
if can_place_building(x, y, current_city_map, building_code):
current_city_map[y][x] = building_code
find_permutations(initial_city_map, current_city_map, building_code, required_building_count - 1, possible_combinations)
def find_possible_combinations(initial_city_map, required_building_count: int) -> List:
building_code = 'B'
possible_combinations = []
current_city_map = copy.deepcopy(initial_city_map)
find_permutations(initial_city_map, current_city_map, building_code, required_building_count, possible_combinations)
return possible_combinations`
</code></pre>

74,415,922 | <p>I have a class with the following property exposed in the .h file:</p>
<pre><code>@property (readonly, nonnull) NSArray<String *> * routeContext;
</code></pre>
<p>As you can see this is a <code>NSArray</code> which is not mutable. In the implementation though I want to be able to work with this array as a mutable one (<code>NSMutableArray</code>) so it will be easy to add, remove objects from it.
What is the best approach to do it?</p>
<p>I was thinking about holder a <code>NSMutableArray</code> in the m file which backs the read only <code>NSArray</code> but it seems kinda dirty to me, is there any other suggestions?
The reason I don't want to set the property to <code>NSMutableArray</code> although its readonly is that readonly doesn't really make sense with <code>NSMutableArray</code>.</p>
<p>Thanks.</p>

74,415,932 | <p>I'm learning Python from Brian Heinold's A Practical Introduction to Python Programming where exercise 24 in chapter 6 reads:</p>
<blockquote>
<p>In calculus, the derivative of <i>x</i><sup>4</sup> is 4<i>x</i><sup>3</sup>. The derivative of <i>x</i><sup>5</sup> is 5<i>x</i><sup>4</sup>. The derivative of <i>x</i>6 is 6<i>x</i><sup>5</sup>. This pattern continues. Write a program that asks the user for input like <code>x^3</code> or <code>x^25</code> and prints the derivative. For example, if the user enters <code>x^3</code>, the program should print out <code>3x^2</code>.</p>
</blockquote>
<p>I figured it out. Easy. However the trick is that should be solved <em><strong>without using <code>int()</code></strong></em> since it has not been mentioned in the book so far. Could you please tell me how to do that?</p>
<p>Here is my solution:</p>
<pre><code>original = input("Enter an x with a power: ")
part1 = original[2:]
part2 = original[0]
part3 = original[1]
part4 = str(int(original[2:])-1)
derivative = part1 + part2 + part3 + part4
print("The derivative is", derivative)
</code></pre>
