<p>Is it possible to target phones (iPhone 14 Pro and iPhone 14 Pro Max) with dynamic islands with React Native?</p>

2022/12/04

<p>I have an <code>AoC</code> problem where I have been given the data below:</p> <pre><code>data = &quot;&quot;&quot;2-4,6-8 2-3,4-5 5-7,7-9 2-8,3-7 6-6,4-6 2-6,4-8&quot;&quot;&quot; </code></pre> <p>I need to find the number of pairs which fully contain another pair. For example, <code>2-8</code> fully contains <code>3-7</code>, and <code>6-6</code> is fully contained by <code>4-6</code>.</p> <p>I have solved it using the below code:</p> <pre><code> def aoc_part1(self, data): counter = 0 for lines_data in data.splitlines(): lines_data = lines_data.strip() first_range, second_range = self.__get_first_second_list_of_elements(lines_data) check_first_side_if_returns_true = all(item in first_range for item in second_range) check_second_side_if_returns_true = all(item in second_range for item in first_range) if check_first_side_if_returns_true or check_second_side_if_returns_true: counter += 1 return counter def __get_first_second_list_of_elements(self, data): first_elf, second_elf = data.split(&quot;,&quot;)[0], data.split(&quot;,&quot;)[1] first_range_start, first_range_end = map(int, first_elf.split(&quot;-&quot;)) second_range_start, second_range_end = map(int, second_elf.split(&quot;-&quot;)) first_range = list(range(first_range_start, first_range_end + 1)) second_range = list(range(second_range_start, second_range_end + 1)) return first_range, second_range </code></pre> <p>I was just wondering about the time complexity here. I think it should be a <code>brute force</code> here because for every iteration <code>all</code> will run another loop. How can I optimize this solution in order to get linear time complexity?</p> <p><code>first_range</code> and <code>second_range</code> are of <code>int</code> types. <code>check_first_side_if_returns_true</code> and <code>check_second_side_if_returns_true</code> are the <code>boolean</code> variables that check if the list is entirely contained or not. Based on that, it returns <code>True</code> or <code>False</code>.</p>

<p>I have a string similar to (the below one is simplified):</p> <pre><code>&quot; word= {his or her} whatever &quot; </code></pre> <p>I want to delete every whitespace except between {}, so that my modified string will be:</p> <pre><code>&quot;word={his or her}whatever&quot; </code></pre> <p>lstrip or rstrip doesn't work of course. If I delete all whitespaces the whitespaces between {} are deleted as well. I tried to look up solutions for limiting the replace function to certain areas but even if I found out it I haven't been able to implement it. There are some stuff with regex (I am not sure if they are relevant here) but I haven't been able to understand them.</p> <p>EDIT: If I wanted to except the area between, say {} and &quot;&quot;, that is:</p> <p>if I wanted to turn this string:</p> <pre><code>&quot; word= {his or her} and &quot;his or her&quot; whatever &quot; </code></pre> <p>into this:</p> <pre><code>&quot;word={his or her}and&quot;his or her&quot;whatever&quot; </code></pre> <p>What would I change</p> <p><code>re.sub(r'\s+(?![^{]*})', '', list_name)</code> into?</p>

<p>I'm working with a pandas Multiindex that is given by the three keys: <br /> [Verbundzuordnung, ProjektIndex, Datum],</p> <p>I would like to resample the dataframe on Datum hourly, which drops the right colum <code>TagDesAbdichtens</code>, I would like to keep it as it's static.</p> <pre><code> Verbundzuordnung ProjektIndex Datum TagDesAbdichtens 1 81679 2021-11-10 00:00:00+00:00 2021-12-08 2021-11-10 00:00:00+00:00 2021-12-08 2021-11-10 00:00:00+00:00 2021-12-08 2021-11-10 00:00:00+00:00 2021-12-08 2021-11-10 00:00:00+00:00 2021-12-08 ... ... ... ... 2 94574 2022-02-28 23:00:00+00:00 2022-01-31 2022-02-28 23:00:00+00:00 2022-01-31 2022-02-28 23:00:00+00:00 2022-01-31 2022-02-28 23:00:00+00:00 2022-01-31 2022-02-28 23:00:00+00:00 2022-01-31 285192 rows × 1 columns </code></pre> <p>There are aditional columns that I left out here for easier comprehension.</p> <p>I am currently applying this to resample the dataframe</p> <pre><code>all_merged = all_merged.groupby([ pd.Grouper(level='Verbundzuordnung'), pd.Grouper(level='ProjektIndex'), pd.Grouper(level='Datum', freq='H')] ) </code></pre> <p>all_merged.mean() gives me the wanted output with <code>TagDesAbdichtens</code> missing.

<p>I'm developing an application inside Visual Studio using C#. This is a simple Console application.</p> <p>In some places, I wish to swallow exceptions. Thus I use an empty <code>catch</code> block. It' by design.</p> <p>When I hit F5, in codes of the <code>try</code> block of that <code>catch</code> block, when exceptions raise Visual Studio breaks on them.</p> <p>This behavior is very annoying and reduces our debugging speed. I want those exceptions to not break at all.</p> <p>How can I do that?</p> <p>I searched the Options menu and I found nothing.</p>

<p>When I tell awt/swing to draw a component at a given y that is smaller than the window height, that object renders on the bottom of the bottom border, but it should not, it is supposed to render at that given y.</p> <p>Here some code example:</p> <pre class="lang-java prettyprint-override"><code> public class Main { public static GameWindow window; public static void main(String[] args) { window = new GameWindow(); } } class GameWindow extends JFrame { private final GamePanel panel; public GameWindow() { super(); this.setSize(600, 400); //Observe that the height is 400 this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); panel = new GamePanel(); this.add(panel); //Uncomment the following line and observe how the square now renders where it should //setUndecorated(true); this.setVisible(true); } //Uncomment the following method to see a black line just on top of the bottom border /*@Override public int getHeight() { return panel.getHeight(); }*/ } class GamePanel extends JPanel { public GamePanel() { super(); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); //Here it should render just above the bottom border, but it doesn't, it renders well below g.fill3DRect(0, Main.window.getHeight() - 22, 22, 22, false); } } </code></pre> <p>Case 1: If you live it decorated, you have to resize the window in order to see the square. Case 2: If you make the JFrame undecorated it renders as it should: just on top of the bottom border. Case 3: If you live it decorated, but override the getHeight method so that it returns the height of the panel, a black line is rendered in the bottom of the window.</p> <p>Images: Case 1: <a href="https://i.stack.imgur.com/v1XuI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/v1XuI.png" alt="Case 1" /></a></p> <p>Case 2: <a href="https://i.stack.imgur.com/R8zvM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/R8zvM.png" alt="Case 2" /></a></p> <p>Case 3: <a href="https://i.stack.imgur.com/molVr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/molVr.png" alt="Case 3" /></a></p>

This is fairly straightforward if I collect first</p> <pre><code># intended output when collecting first remote_data %&gt;% collect() %&gt;% arrange(grp, win) %&gt;% group_by(grp) %&gt;% mutate(last_id = last(id)) %&gt;% ungroup() #&gt; # A tibble: 7 × 4 #&gt; grp win id last_id #&gt; &lt;dbl&gt; &lt;chr&gt; &lt;dbl&gt; &lt;dbl&gt; #&gt; 1 1 A 4 6 #&gt; 2 1 B 7 6 #&gt; 3 1 C 6 6 #&gt; 4 2 A 5 3 #&gt; 5 2 B 1 3 #&gt; 6 2 C 3 3 #&gt; 7 3 C 2 2 </code></pre> <p>However I cannot directly convert this to {dbplyr} code by removing <code>collect()</code>, though the SQL code doesn't look bad, what's happening here ?</p> <pre><code>remote_data %&gt;% arrange(grp, win) %&gt;% group_by(grp) %&gt;% mutate(last_id = last(id)) %&gt;% ungroup() %&gt;% print() %&gt;% show_query() #&gt; # Source: SQL [7 x 4] #&gt; # Database: sqlite 3.39.4 [:memory:] #&gt; # Ordered by: grp, win #&gt; grp win id last_id #&gt; &lt;dbl&gt; &lt;chr&gt; &lt;dbl&gt; &lt;dbl&gt; #&gt; 1 1 A 4 4 #&gt; 2 1 B 7 7 #&gt; 3 1 C 6 6 #&gt; 4 2 A 5 5 #&gt; 5 2 B 1 1 #&gt; 6 2 C 3 3 #&gt; 7 3 C 2 2 #&gt; &lt;SQL&gt; #&gt; SELECT #&gt; *, #&gt; LAST_VALUE(`id`) OVER (PARTITION BY `grp` ORDER BY `grp`, `win`) AS `last_id` #&gt; FROM `dbplyr_001` #&gt; ORDER BY `grp`, `win` </code></pre> <p><code>dbplyr::window_order()</code> allows us to override th ORDER BY clause created by the group_by(), I tried <code>window_order(,win)</code>, but no cookie:</p> <pre><code>remote_data %&gt;% arrange(grp, win) %&gt;% group_by(grp) %&gt;% window_order(win) %&gt;% mutate(last_id = last(id)) %&gt;% ungroup() %&gt;% print() %&gt;% show_query() #&gt; # Source: SQL [7 x 4] #&gt; # Database: sqlite 3.39.4 [:memory:] #&gt; # Ordered by: win #&gt; grp win id last_id #&gt; &lt;dbl&gt; &lt;chr&gt; &lt;dbl&gt; &lt;dbl&gt; #&gt; 1 1 A 4 4 #&gt; 2 1 B 7 7 #&gt; 3 1 C 6 6 #&gt; 4 2 A 5 5 #&gt; 5 2 B 1 1 #&gt; 6 2 C 3 3 #&gt; 7 3 C 2 2 #&gt; &lt;SQL&gt; #&gt; SELECT *, LAST_VALUE(`id`) OVER (PARTITION BY `grp` ORDER BY `win`) AS `last_id` #&gt; FROM `dbplyr_001` #&gt; ORDER BY `grp`, `win` </code></pre> <p>For some reason <code>window_order(,grp)</code> does trigger a window calculation but not with the expected order:</p> <pre><code>remote_data %&gt;% arrange(grp, win) %&gt;% group_by(grp) %&gt;% window_order(grp) %&gt;% mutate(last_id = last(id)) %&gt;% ungroup() %&gt;% print() %&gt;% show_query() #&gt; # Source: SQL [7 x 4] #&gt; # Database: sqlite 3.39.4 [:memory:] #&gt; # Ordered by: grp #&gt; grp win id last_id #&gt; &lt;dbl&gt; &lt;chr&gt; &lt;dbl&gt; &lt;dbl&gt; #&gt; 1 1 A 4 6 #&gt; 2 1 B 7 6 #&gt; 3 1 C 6 6 #&gt; 4 2 A 5 5 #&gt; 5 2 B 1 5 #&gt; 6 2 C 3 5 #&gt; 7 3 C 2 2 #&gt; &lt;SQL&gt; #&gt; SELECT *, LAST_VALUE(`id`) OVER (PARTITION BY `grp` ORDER BY `grp`) AS `last_id` #&gt; FROM `dbplyr_001` #&gt; ORDER BY `grp`, `win` </code></pre> <p>What can I do to keep my initial output with only remote computations, preferably {dbplyr} code ?</p>

<p>I would like to find out how many <code>Users</code> have <code>Swipes</code> per day without duplicates of <code>user_id</code> within group. So if a <code>User</code> has swiped multiple times on a day, I want the <code>User</code> only show once per group (per day). I am not really interested in the actual <code>Swipes</code> but rather in the <code>swipe count</code> per day.</p> <p>I tried:</p> <p><code>Swipe::all()-&gt;groupBy(function($item){ return $item-&gt;created_at-&gt;format('d-M-y'); })-&gt;unique('user_id') </code></p>

<p>I'm having problems with this simple example.</p> <p>The program inquires as to how many letters are required to form a complete word. Then it will ask for each letter individually, which is fine, but I can't make the code save the value from the current character and the next one from the next iteration until the number of letters finishes the word and print it to confirm the word.</p> <p>E.g. Let's say house, which has 5 letters.</p> <pre><code>int numbersOfCharacters=5; int counter=0; char character; string phrase; while (counter &lt; numbersOfCharacters) { cout &lt;&lt; &quot;Introduce character's number&quot; &lt;&lt; counter &lt;&lt; &quot;: &quot;; cin &gt;&gt; character; counter = counter + 1; phrase=character+character; //I'm not sure if I need an array here. } cout &lt;&lt; &quot;Concatenated characters: &quot; &lt;&lt; phrase &lt;&lt; endl; </code></pre> <p>The output is:</p> <pre class="lang-none prettyprint-override"><code>Introduce the character number 1: h Introduce the character number 2: o Introduce the character number 3: u Introduce the character number 4: s Introduce the character number 5: e Concatenated characters: ? </code></pre> <p><strong>And the expected output should be</strong>:</p> <pre class="lang-none prettyprint-override"><code>Concatenated characters: house </code></pre>

<p>I have two models interrelated <strong><code>items</code></strong> and <strong><code>broken</code></strong> :</p> <pre><code>class Items(models.Model): id = models.AutoField(primary_key=True) item_name = models.CharField(max_length=50, blank=False) item_price = models.IntegerField(blank=True) item_quantity_received = models.IntegerField(blank=False) item_quantity_available = models.IntegerField(blank=True) item_purchased_date = models.DateField(auto_now_add=True, blank=False) item_units = models.CharField(max_length=50, blank=False) def __str__(self): return self.item_name class Broken(models.Model): item = models.ForeignKey(Items, default=1, on_delete=models.CASCADE) item_quantity_broken = models.IntegerField(blank=True) item_broken_date = models.DateField(auto_now_add=True, blank=False) item_is_broken = models.BooleanField(default=True) date_repaired = models.DateField(auto_now=True, blank=True) def __str__(self): return self.item.item_name </code></pre> <p>I wrote this <strong>view</strong> function to retrieve data to a table into a template:</p> <pre><code> def broken_items(request): br = Broken.objects.select_related('item').all() print(br.values_list()) context = { 'title': 'broken', 'items': br, } return render(request, 'store/broken.html', context) </code></pre> <p>this is the executing query:</p> <pre><code> SELECT &quot;store_broken&quot;.&quot;id&quot;, &quot;store_broken&quot;.&quot;item_id&quot;, &quot;store_broken&quot;.&quot;item_quantity_broken&quot;, &quot;store_broken&quot;.&quot;item_broken_date&quot;, &quot;store_broken&quot;.&quot;item_is_broken&quot;, &quot;store_broken&quot;.&quot;date_repaired&quot;, &quot;store_items&quot;.&quot;id&quot;, &quot;store_items&quot;.&quot;item_name&quot;, &quot;store_items&quot;.&quot;item_price&quot;, &quot;store_items&quot;.&quot;item_quantity_received&quot;, &quot;store_items&quot;.&quot;item_quantity_available&quot;, &quot;store_items&quot;.&quot;item_purchased_date&quot;, &quot;store_items&quot;.&quot;item_units&quot; FROM &quot;store_broken&quot; INNER JOIN &quot;store_items&quot; ON (&quot;store_broken&quot;.&quot;item_id&quot; = &quot;store_items&quot;.&quot;id&quot;) </code></pre> <p>looks like it gives me all the fields I want.

<p>I have the following tables:</p> <p><code>Students (id, name, surname, study_year, department_id)</code></p> <p><code>Courses(id, name)</code></p> <p><code>Course_Signup(id, student_id, course_id, year)</code></p> <p><code>Grades(signup_id, grade_type, mark, date)</code>, where <code>grade_type</code> can be 'e' (exam), 'l' (lab) or 'p' (project)</p> <p>I want to display the students with their yearly grade (average of the final grade for all courses), but only for those students that have passed ALL the courses that they have signed up for. For example, if a student signs up for 3 courses but only gets a final grade &gt;= 5 to 2 of those courses, that student should not appear in the result. I wrote this so far:</p> <pre><code>SELECT new_table.id, new_table.name, AVG(CASE WHEN grade_type = 'e' THEN new_table.mark END) AS &quot;Average Exam Grade&quot;, AVG(CASE WHEN GRADE_TYPE &lt;&gt; 'e' THEN new_table.mark END) AS &quot;Average Activity Grade&quot;, (2*AVG(CASE WHEN grade_type = 'e' THEN new_table.mark END) + AVG(CASE WHEN GRADE_TYPE &lt;&gt; 'e' THEN new_table.mark END))/3 AS &quot;Course Final Grade&quot; FROM ( SELECT s.id, c.name, g.grade_type, g.mark FROM Students s JOIN Course_Signup csn ON s.id = csn.student_id JOIN Courses c ON c.id = csn.course_id JOIN Grades g ON g.signup_id = csn.id ) new_table GROUP BY new_table.id, new_table.name HAVING ((2*AVG(CASE WHEN grade_type = 'e' THEN new_table.mark END) + AVG(CASE WHEN GRADE_TYPE &lt;&gt; 'e' THEN new_table.mark END))/3) &gt;= 5.00 ORDER BY new_table.id ASC </code></pre> <p>This gives me the students with every course that they promoted. What would be the easiest way to check that a student has a course final grade &gt;= 5, for every course that they signed up for?</p>

<p>I am trying to implement a incremental query in DBT using Jinja.</p> <p>Considering there are tables getting created every month in warehouse with year and month suffix and I need to write a logic to union the new table which gets created every month to execute the DBT model. Below is the code which I have started with</p> <pre><code>#initialize the months in a list {% set months= ['03','04','05','06','07','08','09','10','11','12','01','02'] %} #first select query for Feb month of 2022 SELECT *, '2022-02-01' AS ref_month FROM source_table_2022_02 #initilalize year variable to 2022 {% set year= namespace(items=2022) %} #loop through the months to generate dynamic query for upcoming months {% for month in months %} #if month is Jan increment the year {% if month == '01' %} {% set year.items = year.items + 1 %} {% endif %} UNION ALL SELECT *, '{{ year.items }}-{{ month }}-01' AS ref_month FROM source_table_{{ year.items }}_{{ month }} {% endfor %} </code></pre> <p>output of above logic is as below</p> <pre><code>SELECT *, '2022-02-01' AS ref_month FROM source_table_2022_02 UNION ALL SELECT *, '2022-03-01' AS ref_month FROM source_table_2022_03 UNION ALL SELECT *, '2022-04-01' AS ref_month FROM source_table_2022_04 . . . UNION ALL SELECT *, '2023-02-01' AS ref_month FROM source_table_2023_02 </code></pre> <p>I need help in stopping the for loop when we reach the current month i.e Dec(because there is no current_month method in Jinja and I need to implement this logic in DBT models.sql file and not a python file), instead of looping through the upcoming months.</p> <p>Note: as mentioned earlier the source table gets created every month with year and month suffix</p> <p>I also want to continue the loop after 2023 Feb in the upcoming months. Current logic stops immediately after the list iteration ends i.e 2023 Feb</p>

<p>With boto3 we can create a client for any service of our choice.

<p>I've never tried Javascript before and looked around, but the tutorials I've found would take me weeks to figure out (attention/focus issues + I don't even know what words I want to search for) and none of the solutions I've searched for solved it, and I don't know enough to extrapolate it from other answers.</p> <p>Can someone give me an example of this code (from w3School) extended to also toggle more dropdown menus? It has to be usable with keyboard like this one is.</p> <p><strong>Currently it's only handling the menu with an ID of &quot;dropperso&quot; and can open the Personal menu, I need the &quot;openMenu&quot; function to also react to the ID &quot;dropsites&quot; and be able to open the Other Sites menu. A note that the button and affected ID-having div are siblings.</strong></p> <p>No JQuery please.</p> <p>JS:</p> <pre><code>function openMenu() { document.getElementById(&quot;dropperso&quot;).classList.toggle(&quot;dropopen&quot;); } </code></pre> <p>HTML:</p> <pre><code> &lt;div class=&quot;dropdown&quot;&gt; &lt;button onclick=&quot;openMenu()&quot; class=&quot;drophover&quot;&gt;Other Sites&lt;/button&gt; &lt;div id=&quot;dropsites&quot; class=&quot;dropdown-content&quot;&gt; A link &lt;/div&gt; &lt;/div&gt; &lt;div class=&quot;dropdown&quot;&gt; &lt;button onclick=&quot;openMenu()&quot; class=&quot;drophover&quot;&gt;Personal&lt;/button&gt; &lt;div id=&quot;dropperso&quot; class=&quot;dropdown-content&quot; style=&quot;right: 0;&quot;&gt; A link A link &lt;/div&gt; &lt;/div&gt; </code></pre> <p>All that the .dropopen css class does is change the display of .dropdown-content from none to block.</p> <p>I tried to search for my specific problem and all I found was either way beyond my ability to understand, &quot;use JQuery&quot; (I'm limited and can't use JQuery), or &quot;use this other code (that doesn't work for mine)&quot;.</p> <p>It works if I just copy the whole thing and make one function for each menu, but I get the feeling that's kinda bad spaghetti coding, and I can't compress this on my own without an example that works to learn from.</p> <p>I'd be VERY grateful if you could solve that for me so I can use that later, and even MORE grateful if you could either explain how you made it work or link to the specific parts of documentation that explain what you're using.</p>

My dataframe is something like this:</p> <div class="s-table-container"> <table class="s-table"> <thead> <tr> <th>programme</th> <th>season</th> </tr> </thead> <tbody> <tr> <td>grey's anatomy s1</td> <td>null</td> </tr> <tr> <td>friends season 1</td> <td>1</td> </tr> <tr> <td>grey's anatomy s2</td> <td>null</td> </tr> <tr> <td>big bang theory s2</td> <td>2</td> </tr> <tr> <td>big bang theory</td> <td>1</td> </tr> <tr> <td>peaky blinders</td> <td>1</td> </tr> </tbody> </table> </div> <p>I'd try using regex.</p> <p><code>dt['season_new'] = dt['programme'].str.extract(r'(season\s?\d+|s\s?\d+)')</code></p> <p>But it gave me this result:</p> <div class="s-table-container"> <table class="s-table"> <thead> <tr> <th>programme</th> <th>season</th> <th>season_new</th> </tr> </thead> <tbody> <tr> <td>grey's anatomy s1</td> <td>null</td> <td>1</td> </tr> <tr> <td>friends season 1</td> <td>1</td> <td>1</td> </tr> <tr> <td>grey's anatomy s2</td> <td>null</td> <td>2</td> </tr> <tr> <td>big bang theory s2</td> <td>2</td> <td>2</td> </tr> <tr> <td>big bang theory</td> <td>1</td> <td>null</td> </tr> <tr> <td>peaky blinders</td> <td>1</td> <td>null</td> </tr> </tbody> </table> </div> <p>The result that I expected is:</p> <div class="s-table-container"> <table class="s-table"> <thead> <tr> <th>programme</th> <th>season</th> <th>season_new</th> </tr> </thead> <tbody> <tr> <td>grey's anatomy s1</td> <td>null</td> <td>1</td> </tr> <tr> <td>friends season 1</td> <td>1</td> <td>1</td> </tr> <tr> <td>grey's anatomy s2</td> <td>null</td> <td>2</td> </tr> <tr> <td>big bang theory s2</td> <td>2</td> <td>2</td> </tr> <tr> <td>big bang theory</td> <td>1</td> <td>1</td> </tr> <tr> <td>peaky blinders</td> <td>1</td> <td>1</td> </tr> </tbody> </table> </div>

<p>I have a value x, which is a combination of decision variables.</p> <p>I need to calculate a cost, which only triggers if x &gt; 100. So cost = MAX(x - 100, 0) * 20.</p> <p>Is there any way to do this in linear programming?</p> <p>I've tried creating two binary variables (y1 &amp; y2), in which y1 = 1 when x &lt;= 100 &amp; y2 = 1 when x &gt; 100 &amp; y1 + y2 = 1, from this website - <a href="https://uk.mathworks.com/matlabcentral/answers/693740-linear-programming-with-conditional-constraints" rel="nofollow noreferrer">https://uk.mathworks.com/matlabcentral/answers/693740-linear-programming-with-conditional-constraints</a>.

<p>I'm having the issue (which seems to be common) that I'm dockerizing applications that run on one machine, and these applications, now, need to run in different containers (because that's the docker paradigm and how things should be done). Currently I'm having issues with postfix and dovecot... people have found this too painful that there are tons of containers running both dovecot and postfix in one container, and I'm doing my best to do this right, but the lack of inet protocol examples (over tcp) is just too painful to continue with this. Leave alone bad logging and things that just don't work. I digress.</p> <p><strong>The question</strong></p> <p>Is it correct to have shared docker volumes that have socket files shared across different containers, and expect them to communicate correctly? Are there limitations that I have to be aware of?</p> <p>Bonus: Out of curiosity, can this be extended to virtual machines?</p>

<p>I am trying to understand how Stripe achieves its layout here: <a href="https://stripe.com/docs/payments" rel="nofollow noreferrer">https://stripe.com/docs/payments</a></p> <p>That page has a column flexbox div containing 2 child divs: one for the navbar and the second for the main content. The column direction means that the navbar will sit on top of the main content. The navbar does not use <code>sticky</code> and from what I can see it does not use <code>fixed</code> positioning either.</p> <p>The main content div is a Flexbox with <code>overflow-y: hidden</code> and has 2 child divs: the first for the LHS sidebar and the second for the main page content.</p> <p>Note that left sidebar and main page content scroll independently and the overall page itself does not scroll at all. Unless I misunderstand what is happening, Stripe appears to be using the overflow-hidden property in the primary div to ensure that the page contents div does not go outside the viewport and hence the overall page is not scrollable. The inner divs use <code>overflow-y-auto</code> to ensure that content inside them is scrollable.</p> <p>I'm trying to replicate this using the below using Tailwind and Nextjs:</p> <pre><code>&lt;div class=&quot;h-full bg-white&quot; &gt; &lt;div class=&quot;flex flex-col h-full&quot;&gt; &lt;div id=&quot;Navbar&quot; class=&quot;bg-blue-200&quot;&gt; Navbar &lt;/div&gt; &lt;div id=&quot;MainContent&quot; class=&quot;flex flex-auto h-full overflow-y-hidden&quot;&gt; &lt;div&gt; &lt;div class=&quot;flex-grow-0 flex-shrink-0 flex flex-col h-full w-56 bg-green-100&quot;&gt; &lt;div class=&quot;flex flex-grow overflow-y-auto overflow-x-hidden&quot;&gt; &lt;div&gt; &lt;p&gt;lhs&lt;/p&gt; &lt;p&gt;lhs&lt;/p&gt; ... lots more content here to ensure page overflow &lt;/div&gt; &lt;/div&gt; &lt;div&gt; Sidebar footer &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class=&quot;bg-red-100 w-full&quot;&gt; Content &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>However, when I use the above I just get the whole page that scrolls, whereas I'm expecting to see the LHS sidebar containing the list of <code>&lt;p&gt;las&lt;/p&gt;</code> elements scroll and LHS sidebar footer and the page as a whole to stay static. There is no change when I add a load of content into the content div. Here's what it looks like: <a href="https://play.tailwindcss.com/J6unFAO47B" rel="nofollow noreferrer">https://play.tailwindcss.com/J6unFAO47B</a></p> <p>Whilst I know that I could use a <code>sticky</code> navbar, I'm trying to understand what Stripe is doing in their page and so I want to understand why is my sidebar not scrolling independently of the other areas of the page?</p>

<p>Using Entity Framework core, can I get the total sum of the column and row count in one call? I have the following code, but I think there is a better way to do this.</p> <pre class="lang-cs prettyprint-override"><code>TotalCostResponse result = new TotalCostResponse { TotalCost = await dbContext.Transaction .Where(x =&gt; x.UserName == request.UserName &amp;&amp; x.Date &gt;= request.StartDate &amp;&amp; x.Date &lt;= request.EndDate) .SumAsync(x =&gt; x.Amount), TotalNumber = await dbContext.Transaction .Where(x =&gt; x.UserName == request.UserName &amp;&amp; x.Date = request.StartDate &amp;&amp; x.Date &lt;= request.EndDate) .CountAsync() }; </code></pre> <p>So instead of calling dbContext two times, I need to make it in one call.</p>

I need to compare the legacy header with the second csv's current headers, so after i append the data from the first csv i want to move it so that it's the first row too.</p> <p>The issue right now is that when i append my data from the first csv it just all goes to the bottom of the first column.</p> <p>See below for my code. How can i make it so that it takes the 1 row of data in my first csv and appends it to my second csv as ONE NEW ROW.

The problem is I don't know how to check whether the checkbox is empty or not.</p> <p>Below is the partial form for the filter dropdown:</p> <pre><code>&lt;form class=&quot;&quot; method=&quot;GET&quot; action=&quot;manage_product.php&quot;&gt; &lt;h6 class=&quot;dropdown-header px-0&quot;&gt;Gender&lt;/h6&gt; &lt;div class=&quot;form-check&quot;&gt; &lt;input class=&quot;form-check-input&quot; name=&quot;genderFil[]&quot; type=&quot;checkbox&quot; value=&quot;M&quot; class=&quot;genderFil&quot; id=&quot;genMale&quot; &lt;?= ($isMale == 1) ? &quot;checked&quot; : &quot;&quot;; ?&gt;&gt; &lt;label class=&quot;form-check-label&quot; for=&quot;genMale&quot;&gt;Male&lt;/label&gt; &lt;/div&gt; &lt;div class=&quot;form-check&quot;&gt; &lt;input class=&quot;form-check-input&quot; name=&quot;genderFil[]&quot; type=&quot;checkbox&quot; value=&quot;F&quot; class=&quot;genderFil&quot; id=&quot;genFemale&quot; &lt;?= ($isFemale == 1) ? &quot;checked&quot; : &quot;&quot;; ?&gt;&gt; &lt;label class=&quot;form-check-label&quot; for=&quot;genFemale&quot;&gt;Female&lt;/label&gt; &lt;/div&gt; &lt;div class=&quot;dropdown-divider&quot;&gt;&lt;/div&gt; &lt;h6 class=&quot;dropdown-header px-0&quot;&gt;Category&lt;/h6&gt; &lt;div class=&quot;form-check&quot;&gt; &lt;input class=&quot;form-check-input&quot; name=&quot;categoryFil[]&quot; type=&quot;checkbox&quot; value=&quot;1&quot; class=&quot;categoryFil&quot; id=&quot;catShoes&quot; &lt;?= ($isShoes == 1) ? &quot;checked&quot; : &quot;&quot;; ?&gt;&gt; &lt;label class=&quot;form-check-label&quot; for=&quot;catShoes&quot;&gt;Shoes&lt;/label&gt; &lt;/div&gt; &lt;div class=&quot;form-check&quot;&gt; &lt;input class=&quot;form-check-input&quot; name=&quot;categoryFil[]&quot; type=&quot;checkbox&quot; value=&quot;2&quot; class=&quot;categoryFil&quot; id=&quot;catPants&quot; &lt;?= ($isPants == 1) ? &quot;checked&quot; : &quot;&quot;; ?&gt;&gt; &lt;label class=&quot;form-check-label&quot; for=&quot;catPants&quot;&gt;Pants&lt;/label&gt; &lt;/div&gt; &lt;div class=&quot;form-check&quot;&gt; &lt;input class=&quot;form-check-input&quot; name=&quot;categoryFil[]&quot; type=&quot;checkbox&quot; value=&quot;3&quot; class=&quot;categoryFil&quot; id=&quot;catShirts&quot; &lt;?= ($isShirts == 1) ? &quot;checked&quot; : &quot;&quot;; ?&gt;&gt; &lt;label class=&quot;form-check-label&quot; for=&quot;catShirts&quot;&gt;Shirts&lt;/label&gt; &lt;/div&gt; &lt;div class=&quot;dropdown-divider&quot;&gt;&lt;/div&gt; &lt;input type=&quot;submit&quot; class=&quot;button_primary&quot; name=&quot;applyFilter&quot; value=&quot;Apply&quot; onclick=&quot;checkFilter()&quot;&gt; &lt;/form&gt; </code></pre> <p>Below is the javascript that I tried to code:</p> <pre><code> function checkFilter() { var res = true; var checkedGender = $('input[class=&quot;genderFil&quot;]:checked').length; if(checkedGender &lt; 1) { alert(&quot;Please select at least one gender!&quot;); res = false; } var checkedCategory = $('input[class=&quot;categoryFil&quot;]:checked').length; if(checkedCategory &lt; 1) { alert(&quot;Please select at least one category!&quot;); res = false; } return res; } </code></pre> <p>It is only can be submitted if there is at least one gender and at least one category checked.</p> <p>How can I check whether the checkbox is empty or not?</p>

<p>Sorry for the strange title, but I've come across an issue that is plain weird. To give some background, i'm working on a booking system that takes a time range as an input from admin, generates available times based on it, and then reduces the available times based on already made bookings (i.e admin specifies availability from 10:00 to 12:00, booking has been made to 11:30, available times will be <code>times = [10:00, 10:30, 11:00, 12:00]</code>).</p> <p>I have an object that contains per month for each day the available times.</p> <pre><code>availableTimesPerDay: { 1: [&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;], 2: [&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;], 3: [&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;], .... } </code></pre> <p>Where the number represents the date for the given month.</p> <p>Bookings are represented as an array of objects, format is:</p> <pre><code>bookedTimes = [ { date: &quot;2022-12-01T11:30:00.000+02:00&quot; } ]; </code></pre> <p>I planned to have a function which would iterate through each booking and remove the availability for that time on a given date (based on example above, 11:30 would need to be removed from <code>availableTimesPerDay[1]</code> leaving the value for it as <code>[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;]</code></p> <p>The function itself is defined as such:</p> <pre><code>function reduceAvailableTimesBasedOnDateTime(availableTimesPerDay,bookedTimes){ console.log(JSON.stringify(availableTimesPerDay)); bookedTimes.forEach((bookedDateObject) =&gt; { let bookedDate = new Date(bookedDateObject.date); // 1 let currentAvailableTimesOnDate = availableTimesPerDay[bookedDate.getDate()]; // [&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;] let bookedTime = bookedDate.toLocaleTimeString('et'); // &quot;13:30:00&quot; let time = bookedTime.substring(0,bookedTime.length - 3); // &quot;13:30&quot; let index = currentAvailableTimesOnDate.indexOf(time); // 3 if (index &gt; -1) { currentAvailableTimesOnDate.splice(index, 1); // [&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;] } }) console.log(JSON.stringify(availableTimesPerDay)); return availableTimesPerDay; } </code></pre> <p>The way I understand this function is that i've extracted a specific array of available times into a new variable and removed a specific time from that array. I have done no modifications on an original data and I would expect at this stage the <code>availableTimesPerDay</code> to remain unmodified. However, when I run my code, the <code>availableTimesPerDay</code> is modified even though I do no operations with <code>availableTimesPerDay</code> object itself.</p> <p>What's even stranger is that the modification is not just strictly done on the 1st element, but on all specific dates that have the same day of the week. Here's output from the console for the <code>console.log(availableTimesPerDay)</code> defined in the function (note that <code>11:30</code> value is removed on dates 1st of December, 8th of December, 15th of December etc.</p> <pre><code>booking-helper.js:94 {&quot;1&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;],&quot;2&quot;:[],&quot;3&quot;:[],&quot;4&quot;:[],&quot;5&quot;:[],&quot;6&quot;:[],&quot;7&quot;:[],&quot;8&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;],&quot;9&quot;:[],&quot;10&quot;:[],&quot;11&quot;:[],&quot;12&quot;:[],&quot;13&quot;:[],&quot;14&quot;:[],&quot;15&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;],&quot;16&quot;:[],&quot;17&quot;:[],&quot;18&quot;:[],&quot;19&quot;:[],&quot;20&quot;:[],&quot;21&quot;:[],&quot;22&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;],&quot;23&quot;:[],&quot;24&quot;:[],&quot;25&quot;:[],&quot;26&quot;:[],&quot;27&quot;:[],&quot;28&quot;:[],&quot;29&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;11:30&quot;,&quot;12:00&quot;],&quot;30&quot;:[],&quot;31&quot;:[]} booking-helper.js:105 {&quot;1&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;],&quot;2&quot;:[],&quot;3&quot;:[],&quot;4&quot;:[],&quot;5&quot;:[],&quot;6&quot;:[],&quot;7&quot;:[],&quot;8&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;],&quot;9&quot;:[],&quot;10&quot;:[],&quot;11&quot;:[],&quot;12&quot;:[],&quot;13&quot;:[],&quot;14&quot;:[],&quot;15&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;],&quot;16&quot;:[],&quot;17&quot;:[],&quot;18&quot;:[],&quot;19&quot;:[],&quot;20&quot;:[],&quot;21&quot;:[],&quot;22&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;],&quot;23&quot;:[],&quot;24&quot;:[],&quot;25&quot;:[],&quot;26&quot;:[],&quot;27&quot;:[],&quot;28&quot;:[],&quot;29&quot;:[&quot;10:00&quot;,&quot;10:30&quot;,&quot;11:00&quot;,&quot;12:00&quot;],&quot;30&quot;:[],&quot;31&quot;:[ </code></pre> <p>What's even more interesting is that if I copy the same function to codepen with same data or call it directly from the browsers console it works as expected - it removes the specific time from a specific date.</p>

<p>I am trying to use the same ref for multiple input fields in for my form. But on logging it, the ref refers only to the first input field.

<p>I made a simple react hook.</p> <pre class="lang-js prettyprint-override"><code>import React from &quot;react&quot;; import { useNavigate } from &quot;react-router-dom&quot;; export default function SearchReq(searchTerm: string) { if (searchTerm === &quot;&quot;) return; const navigate = useNavigate(); console.log(searchTerm); // window.location.href = &quot;/search?searchTerm=&quot; + searchTerm; navigate(&quot;/search?searchTerm=&quot; + searchTerm, { replace: true }); } </code></pre> <p>But for some reason it is giving me an error I had figured out that the line that is causing an error is <code>const navigate = useNavigate()</code> but I don't understand why can any one explain it to me?</p> <p>Here is the error: <a href="https://i.stack.imgur.com/e49IR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/e49IR.png" alt="enter image description here" /></a></p>

<p>I have a problem where the line of codes in my Update function does not work. I added a debug.log both at the start and end of the update function but the whole if statement does not work. The <code>dialogCycle</code> variable does not even increment. Is there something wrong with the whole script?</p> <p>Here is the script:</p> <pre><code>using System; using System.Linq; using TMPro; using UnityEngine; using UnityEngine.UI; public class TelevisionEvent : MonoBehaviour { [SerializeField] private GameData gameData; // SCRIPTABLEOBJECT [SerializeField] private GameObject dialogbox, interactButton; [SerializeField] private FollowPlayer followPlayer; [SerializeField] private Transform tv, player; [SerializeField] private TextAsset objectData; private ObjectDialog objectJson; public string[] dialogMessage; public int dialogCycle; public bool clickEnable; private void Update() { //if (gameData.isWatched) return; if (Input.GetMouseButtonDown(0) &amp;&amp; clickEnable) { Debug.Log(&quot;Clicked&quot;); // THIS WORKS dialogCycle++; // I PUT THIS OUTSIDE TO CHECK IF IT WILL WORK OUTSIDE THE IF BUT IT STILL DOES NOT tvDialog(); // THE DEBUG.LOG IS THE ONE THAT ONLY WORKS if (dialogCycle != dialogMessage.Length - 1) // BUT THIS WHOLE IF STATEMENT DOES NOT GET CHECKED { dialogCycle++; tvDialog(); } else { dialogbox.SetActive(false); dialogCycle = 0; Array.Clear(dialogMessage, 0, dialogMessage.Length); clickEnable = false; gameData.isWatched = true; followPlayer.player = player; } Debug.Log(&quot;Clicked2&quot;); // THIS WORKS TOO } } private void OnTriggerEnter(Collider collisionInfo) { if(gameData.isWatched) return; if (collisionInfo.CompareTag(&quot;Player&quot;)) { interactButton.GetComponent&lt;Button&gt;().onClick.RemoveListener(tvDialog); interactButton.GetComponent&lt;Button&gt;().onClick.AddListener(tvDialog); } } private void OnTriggerExit(Collider collisionInfo) { Debug.Log(&quot;Hello&quot;); if (gameData.isWatched) return; if (collisionInfo.CompareTag(&quot;Player&quot;)) { interactButton.GetComponent&lt;Button&gt;().onClick.RemoveListener(tvDialog); } } public void tvDialog() { dialogbox.SetActive(true); interactButton.SetActive(false); dialogCycle = 0; followPlayer.player = tv; objectJson = JsonUtility.FromJson&lt;ObjectDialog&gt;(objectData.text); loadDialog(); } public void loadDialog() { dialogbox.transform.GetChild(0).GetComponent&lt;TextMeshProUGUI&gt;().text = objectJson.name; dialogMessage = objectJson.object_dialog.Split('#'); dialogbox.transform.GetChild(1).GetComponent&lt;TextMeshProUGUI&gt;().text = dialogMessage[dialogCycle]; clickEnable = true; } } </code></pre> <p>For more info, the game object that it is attached to have another script. Will it have an effect in this script? the other script is just like this but it is like an object interaction manager for the map (opening doors, etc.).</p> <p><a href="https://i.stack.imgur.com/lQVF9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lQVF9.png" alt="inspector" /></a></p> <p>By 'just like this' I mean there is also a line of codes similar to the prior script above. The script above is for an event when the player opens the door for the first time a television dialogue event will trigger. In the other script, I have the object interaction where I interact with object like a radio and the dialogue will show.</p> <p>I can just show you the script just for more info. the similarities will be in the update function and the last part of the script which is the <code>objectDialog</code> method</p> <pre><code>using System;

<p>Given an NxM matrix A, I want to efficiently obtain the NxMxN tensor whose ith layer is the application of np.minimum between A and the ith row of A. Using a for loop:</p> <pre><code>&gt; A = np.array([[1, 2], [3, 4], [5,6]]) &gt; output = np.zeros(shape=(A.shape[0], A.shape[1], A.shape[0])) &gt; for i in range(a.shape[0]): output[:, :, i] = np.minimum(A, A[i]) &gt; output array([[[1., 1., 1.], [2., 2., 2.]], [[1., 3., 3.], [2., 4., 4.]], [[1., 3., 5.], [2., 4., 6.]]]) </code></pre> <p>This is very slow so I would like to get rid of the for loop and vectorize it. I feel like there should be a general method that works with any function of a matrix and a vector not just, minimum. Using np.minimum.outer does not work as it outputs an order 4 tensor.</p>

<p>I have the following question. I have generated the following RowNumber column by usage of the rownumber() function and the over(paritation by clause.

<p>So I am trying to update a record with multiple fields in my database using laravel, however I am trying to validate the input first before proceeding with the actual updating of the record.</p> <p>So my problem is that one of my field has to be unique and should allow the other fields to be edited even if that field is not edited.</p> <p>I know that in the document it is that we can use this code to do that.</p> <pre><code>use Illuminate\Support\Facades\Validator; use Illuminate\Validation\Rule;   Validator::make($data, [ 'email' =&gt; [ 'required', Rule::unique('users')-&gt;ignore($user-&gt;id), ], ]); </code></pre> <p>However, the id that is supposed to be used in the ignore method is also validated.</p> <pre><code>'product_id' =&gt; 'required|string|exists:' .

<p>whenever I refresh my page the fetched content I've loaded decides to disappear, it will load the first time but every time after that it will go. I have another component that has almost the same code and that one works fine so I'm not entirely sure why it doesn't with this component.</p> <p>the feeling I have is in my standings.svelte component I have a flatMap function which is the main difference compared to my other components.</p> <p>here is a video showing what happens when I refresh the page. This won't happen to any other component but this one. (<a href="https://imgur.com/a/Ew4bwgB" rel="nofollow noreferrer">https://imgur.com/a/Ew4bwgB</a>)</p> <p>This is my standings.svelte component</p> <pre><code>&lt;script&gt; import {leagueStandings} from &quot;../../stores/league-standings-stores&quot; const tablePositions = $leagueStandings.flatMap(({ standings: { data } }) =&gt; data); &lt;/script&gt; &lt;div class=&quot;bg-[#1C1C25] p-8 rounded-lg box-border w-fit&quot;&gt; {#each tablePositions as tablePosition} &lt;div class=&quot;standings-table flex gap-9 mb-2 pb-4 pt-3 border-b border-[#303041]&quot;&gt; &lt;div class=&quot;team-details flex gap-4 w-full&quot; id=&quot;td&quot;&gt; &lt;p class=&quot;w-[18px]&quot;&gt;{tablePosition.position}&lt;/p&gt; &lt;img src=&quot;{tablePosition.team.data.logo_path}&quot; alt=&quot;&quot; class=&quot;w-[1.5em] object-scale-down&quot;&gt; &lt;p class=&quot;&quot;&gt;{tablePosition.team_name}&lt;/p&gt; &lt;/div&gt; &lt;div class=&quot;team-stats flex gap-5 text-left child:w-5 child:text-center w-full&quot;&gt; &lt;p&gt;{tablePosition.overall.games_played}&lt;/p&gt; &lt;p&gt;{tablePosition.overall.won}&lt;/p&gt; &lt;p&gt;{tablePosition.overall.draw}&lt;/p&gt; &lt;p&gt;{tablePosition.overall.lost}&lt;/p&gt; &lt;p&gt;{tablePosition.overall.goals_scored}&lt;/p&gt; &lt;p&gt;{tablePosition.overall.goals_against}&lt;/p&gt; &lt;p&gt;{tablePosition.total.goal_difference}&lt;/p&gt; &lt;p&gt;{tablePosition.overall.points}&lt;/p&gt; &lt;p class=&quot;!w-[78px] !text-left&quot;&gt;{tablePosition.recent_form}&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; {/each} &lt;/div&gt; </code></pre> <p>Here is my svelte store</p> <pre><code>import { writable } from &quot;svelte/store&quot;; export const leagueStandings = writable([]); const fetchStandings = async () =&gt; { const url = `https://soccer.sportmonks.com/api/v2.0/standings/season/19734?api_token=API_KEY`; const res = await fetch(url); const data = await res.json(); leagueStandings.set(data.data); } fetchStandings(); </code></pre> <p>id love some advice on what im doing wrong :)</p>

<p>Within a very large HTML page i want to get a <code>span</code> by <code>class</code> which is unique. The <strong>child</strong> <code>span</code> of this one, can be queried also by <code>class</code> but which is <strong>not unique</strong>.</p> <pre><code>... &lt;span class=&quot;uniqueParent&quot;&gt; &lt;span class=&quot;notUniqueChildClassName&quot;&gt; I am the child &lt;/span&gt; &lt;/span&gt; ... </code></pre> <p>Output should be &quot;I am the child&quot;.</p> <p>I have tried:</p> <pre><code>s = soup.select('span[class=&quot;uniqueParent&quot;] &gt; span[class=&quot;notUniqueChildClassName&quot;]') s.text </code></pre> <p>and</p> <pre><code>s = soup.find('span[class=&quot;uniqueParent&quot;] &gt; span[class=&quot;notUniqueChildClassName&quot;]') s.text </code></pre> <p>But both did not work.</p>

<p>I want to add a confirmation to a form action:</p> <pre><code> &lt;form action=&quot;/delete&quot; method=&quot;post&quot;&gt; &lt;button id=&quot;deleteForm&quot; class=&quot;btn btn-danger&quot; onclick=&quot;deleteConfirm(this.form)&quot;&gt;Delete&lt;/button&gt; &lt;/form&gt; </code></pre> <p>And in my script.js I wrote the function:</p> <pre><code>function deleteConfirm() { let text = &quot;Are you sure?\nOk=Delete all data.&quot;; if (confirm(text) == true) { document.getElementById(&quot;deleteForm&quot;).submit(); } else { alert(&quot;Cancelled.&quot;); } } </code></pre> <p>But with these codes when I click either ok or cancell, the form will submit. when I click cancel the alert show up but then the action /delete will execute.</p> <p>Is this an attribute of flask? Are there another ways to do this?</p>

<p>public static String input(){</p> <pre><code>Scanner input = new Scanner(System.in); String key = &quot;&quot;; while(key != &quot;q&quot;){ key += input.nextLine(); return key; } return &quot;hello&quot;; </code></pre> <p>} //if input is &quot;1234&quot; then it should return key = &quot;1234&quot;,</p> <p>if the input is &quot;1234q&quot; then it should return &quot;hello&quot;</p> <p>The output im getting is &gt;nothing&lt; until I do it twice, and then it returns key = &quot;1234q&quot;</p> <p>How can I fix this? Thanks</p>
