space | real time chat app for developers built using React | Authentication library

I've been struggling with this all over my react-native app, so I set up a very simple example of it in codesandbox which you can view here:

https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js

Within the View with the green background, all of the internal views are centered horizontally within their respective spaces as I would expect thanks to the "alignItems: center" style property. I would expect that I could also center them vertically within their spaces by setting "justifyContent: center", but that doesn't seem to work for me.

Am I fundamentally misunderstanding something?

I am trying to write the following C code in Metal Shading Language inside of a kernel void function:

When I hover over the anchor tag, it flickers. It's because there are vertical gaps between the lines of the wrapped anchor tag. Moreover, if I happen to click between the lines, the link doesn't activate. I would like to get rid of this flickering and vertical hover gaps that cause it. The rest of the layout including apparent line height and button position (on the same line as the last word of the anchor tag) should stay the same.

I was thinking about this for a couple of days with no luck. The best alternative I have is using inline-block on the anchor tag, but that clears the button to the next line, which wastes too much space.

I am having problems getting data from a element using Selenium with the line:

I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03 at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03') will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:

the swiftui code below should apply the sephia.tone filter to the current photo, to do it I used the code below but the filter is not applied, can anyone explain to me where the problem is? when I click on sepia I make the call to the function that applies the CiFilter,what is this due to? because the filter is not applied correctly

Swift UI Code:

I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.

So I was wondering if there is a way to make a batch file read a separate text document and convert specific lines of code into a variable with the same value given, as from the document. So make the batch script read the text document, and use the information in there to create it's own variable. eg.

TEXT.txt:

A part of my form contains QGroupBox (Status Box) with 4 child QGroupBoxes arranged in a grid layout (2x2). Two bottom QGroupBoxes (Widget 1 Box and Widget 2 Box) contain widgets of fixed size (with set minimumSize and maximumSize) so they're non-resizable at all in both directions. Because of that rigid size constraints top row of QGroupBoxes (Summary Box and Helper Box) can only be resized in vertical direction.

And here comes the troublesome part. Top-left QGroupBox (Summary Box) have grid layout 5x3 while top-right (Helper Box) have vertical layout with 6 rows. If I have naive widget placement as shown on picture 1 Qt is enlarging vertical size of both labels in top row to make height of both QGroupBoxes equal (see red arrows on picture 1).

This is definitely that I don't want so I've added vertical spacer to the bottom of Summary Box and from the first glance it worked (picture 2). But only from the first glance... What you see is the minimum height of my whole form and the bottom side of spacer and last QCheckBox in the Helper Box seems to be aligned.

If I'm expanding my form vertically this spacer grows a bit and that causes the increase of height of both top QGroupBoxes. As a result spacing between QCheckBoxes increases too and we can also see that top and bottom spacing are unequal for the top-right box (see red arrows on picture 3).

I've tried to play with sizeType for my vertical spacer. If I set it to Minimum or MinimumExpanding then the spacer doesn't grow on resize (and doesn't shrink, too) but it appears to be expanded to the size as on picture 3 (corrupting spacings between QCheckBoxes too). If I set it to Maximum, Preferred or Expanding then I observe the same behavior as described above for picture 3.

What is the proper way to achieve alignment for two QGroupBoxes in a row of grid without affecting spacing between elements (e. g. in that case make vertical spacer to fit only single row of grid layout and never expand/shrink)?
