Welcome to Software Development on Codidact!
Will you help us build our independent community of developers helping developers? We're small and trying to grow. We welcome questions about all aspects of software development, from design to code to QA and more. Got questions? Got answers? Got code you'd like someone to review? Please join us.

The term is cultural, not technical. From Wikipedia: There is no standard for defining the term, and some difference of opinion is possible as to the degree to which a given operating system or ...
Python doesn't support extending the mechanics of how f-strings are parsed; the reference doesn't give the specific mechanism, but it doesn't say that there's any connection between the parsing of ...
Your code is correct. You have declared your variable as an array, and you are successfully appending to it. To display all of the elements of your variable, try echo "${my_array[@]}". (Another an...
‘This language doesn't have types’ and ‘This language only has one type’ are English sentences that communicate the same underlying concept: a typeless language doesn't have a way to distinguish ca...
It's because of this rule: *{ background: rgb(3, 28, 87); } That applies the darker blue background to every element individually, and that isn't overridden when you change the background o...
For writing pseudocode? No. BNF is a notation—in practice, a family of similar notations, like how Markdown is a family of similar markup languages—for defining grammars. In software development a...
There are a few reasons for wanting to move computation closer to data. One is performance, which you've mentioned. Another is security. Databases enforce their own security boundary, and data that...
See this comment: https://forum.qt.io/topic/60546/qpushbutton-default-windows-style-sheet#3 Stylesheets are a totally different beasts. The default native drawing doesn't use stylesheets. They ...
I propose adding, at the top of the list: On-topic questions about writing software, where software is understood to include any means of specifying to a computer actions to be performed later. (...
fn x [] = [] means that if the second argument to fn is an empty list, return an empty list. fn x (True:ys) = x : fn x ys means that if the second argument to fn starts with True, return a list th...
This looks like it's a slightly restricted version of the circular dilation minimization problem in the theory of graph drawing. See, for example, https://doi.org/10.1080/00207168808803629. Specif...
From the command line, the following command will give you a list of all authors who have made local-only commits to a branch some-branch: git log some-branch --not --remotes --format="%an" And...
There is no fixed number of days in a MONTH interval. DATE_SUB is mostly just decrementing the number in the months position of the date provided. So DATE_SUB('2020-09-14', INTERVAL 3 MONTH) is '20...
In my opinion, all of the downsides boil down to two objections: It isn't idiomatic (in C# and VB.NET) It's slightly less performant The fact that it isn't idiomatic means that, as you note...
No, you can't use and for this. In Python, a and b always, always, always means b if a else a. It cannot be overridden and cannot mean anything else. Likewise not, and any other boolean keywords, ...
This error doesn't do a good job at all of highlighting the important thing! You can't define an inherent impl on a type parameter. You have to make it the impl of some trait. Here's an example: Tr...
I remember reading @meriton's comments on that question and thinking they were good feedback; if I hadn't seen them there, I would have written something similar. This is also an argument against ...
Switching from HTML to Markdown to minimize risk of HTML injection doesn't make a lot of sense to me, since most Markdown implementations support a subset of HTML inline anyway. The better ones con...
Simply opening a file for writing (using fopen) will clear it (‘truncate to zero length’, per the standard). Only opening a file in read or append mode will preserve its contents. See section 7.21...
There's one big difficulty with the proposed pattern. Enum instances are singleton instances of their particular class, and in general two enums from different classes are not equal even if they wr...
Off-topic questions about which tools, frameworks, or technologies to use, unless they are directly related to development (e.g. code, schema changes documentation tools) I propose removing thi...
For holding ordered sets of keys, there are well-known data structures (the red-black tree, for example) that support O(log(n)) lookup and insertion algorithms. Of course this means that there triv...
You could trivially create a view that wraps the media table and includes a column that indicates if the media entry has more than one file associated with it. CREATE VIEW IF NOT EXISTS "media_rea...
Remember that jQuery selectors in general can match more than one element. If you had multiple <p> elements in your page, $('p').wrap(wrapper) would put wrapper divs around each of them. So ....
It isn't writable (but then again, neither are the dictionary views), but you might be interested in more_itertools.SequenceView.
