I'm building an example REST API in PHP in my local environment to learn how they work. The starting point was an online tutorial. The example is working fine; however, I have a hunch that there is room for improvement in the logic that handles the endpoints which is stored in a script called R...
this question is short and simple, I would like to know what's the whole point in returning an object in a fuction as constant or as non-constant.
I was reading about 'return constant reference', and I understand the point of returning as reference, basically to don't make a copy, but what's te ...
I created a basic app using Rails 6 and wanted to have better control over my styles. My app/assets/stylesheets were like this and everything was fine:

Coursera has a course for beginning Machine Learning and the code is written in Octave. This is the beginning of a solution to the week 3 exercises but written in python. Instead of a terminal app I'm also trying to learn Pyside2. The actual functionality of the program may seem silly but I hope...
This is an interesting example from G.Lanaro book, 'Python High Performance'. The program is a simple simulator which describes movement of particles based on their positions and angular velocities (x,y and ang_v attributes of Particle class). The bottleneck of the program is the evolve() method ...
Here's how I'd usually center align an item with absolute positioning:

top: 50%;
left: 50%;
transform: translate(-50%, -50%);
z-index: 9999;
background: #fff;

}

This thing takes too long, and I think it's because the insertion process takes too much time for map is constructed in rbt.

When I'm working on an issue on my git repo, I create a branch called iXXX (where XXX identifies the issue number). After I finish working on this branch, my steps are always as follows:

As many of you may have noticed, Monica Cellio is no longer a moderator on Writing.SE, or on any of the several stacks where she has served for years. This was due to a sudden decision by Stack Exchange staff and was not Monica’s choice (or ours). She remains a SE user with no change in reputat...
I've been learning C# for a few months now, and I've done some basic things in java last year.

nucleotides in the sequence. Each ...
What's better - to leave the IF block blank to do nothing, or to add a statement that basically does nothing (each link already has a href attribute)?

I'm practicing using structured bindings from Jacek Galowicz's C++17 STL Cookbook. I created a wrapper code around the example to run it.
Tried with clang, GNU, but it seems not being able to decompose non-public member somewhere.

Recently I was studying about the benefits and uses of std::optional in C++17 (Bartek's Blog) and there I saw a line that said "std::optional can be used for Lazy Loading of Resources" . Upon digging a little bit, I saw that C++ does not have native support for Lazy evaluation. So I just gave it ...
I hope the title makes sense, I wasn't sure how to ask it.
So as we know, using PDO and prepared statement, binding a table or column using bindParam is not possible. So for this, I've figured out to use function parameters to do it by replacing the column names with the parameters, as shown in ...
For several years we've had advertising solely on technology-related sites. But many of our sites aren't about technology at all, so we haven't sold ads for them. Traditionally, that hasn't been a hardship since Stack Exchange sites have required only a small investment from the company to set up...
About four seconds before this was post - literally, four seconds - I amended a Worldbuilding meta post I had written, to state specific concerns I had about the entire situation. Here's what I added:

Your actions have harmed the Lavender Community here at SE.
I have taken a leave of absence effective today. This means Writing.SE has no active moderator.
As a queer user I used to feel safe here on SE. Monica's skillful and caring moderation was a large part of why. Now I don't.

In light of recent events I intended to write a simple letter of complaint to StackExchange. The obvious thing to do would be to write an opening with the fact such as

I have been using similar piece of code since a while.
I have read some issues regarding treating mapped memory as a string. I am not sure about that though.
So I just use strndup(3) to avoid it anyway. Wanted some reviews on this code:

I am loathe to post an answer here, because the community is especially charged right now. However, I feel I must speak out.
Full Disclosure: I am trans. I'm not really open about this fact with SE, though I did recently out myself on Parenting.

Most quicksort examples online use C-style arrays and indexes. I have written below quicksort implementation with STL style iterators. It looks fine to me, but I feel like I may be making more than necessary copies of iterators. I am open for any suggestions/improvements:
