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.

What is the purpose of grouping the tests in a tests module like this #[cfg(test)] mod tests { use super::*; #[test] fn test_function_1() { // test code for function 1 g...
I have a variable that contains a string: $CCSR = "branches/features/arm_and_musl" I want to get only the part after the last /. In this case it's "arm_and_musl" but it can be anything. So som...
While I agree with Dirk Herrmann that basename is the right tool for the job, I think it is still worthwhile to know how to do it with grep, because you might one day encounter a sufficiently simil...
After spending my time on SO, I found that some of the FAQ style questions were VERY helpful, especially with things such as SQL injection in PHP/MySQL (for example How can I prevent SQL injection ...
Context We have recently received a suggestion to allow questions about recommending books directly connected to software development. The way I see this now (pros and cons) Pros: allow more ...
I've heard that in modern C++, smart pointers are preferred to raw pointers for ownership (the so-called RAII principle, as I understand it). This makes sense, and since then I've always used them...
Before doing any performance testing, I think you have already noticed that the payload is significantly smaller by missing those double quotes. However, what I think is more important, especially ...
Yes, it is generally good practice to always cast the return value of functions to (void) if not used. This is self-documenting code showing that you aren't using the return value on purpose and di...
I personally have several (10s) of Q&A where I posted the question and\or answer, on related SE sites. These Q&A are ones I go back to for reference for myself and others. I know and under...
My work tasks have recently started requiring me to use the type_traits header to restrict the classes that may be used in template functions, methods, and classes. And while I used it for a long t...
questions about software design, software architecture, or modeling questions related to software design/review - what item goes where when using a certain technology stack These seem redundant...
Consider the following posts which have essentially become canonical references in their own right within their respective communities on SE: The Definitive C++ Book Guide and List (viewed 2.5 mil...
questions about best practices as long as enough detail is provided to answer using external references or expertise consensus It's not a "detail" if it is essential, is it? Can we explicitly sta...
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...
Oooops. You have discovered my little secret superpower. Just kidding of course. (Unfortunately) I closed the first question upon some flags. On the second post, there was a spam answer, which...
When I open the search, I can only search across all categories of this site. I'd like to filter down the search results to only Meta (or Code review).
I recently encountered a strange situation in javascript; if I have: let obj = { a: function() { return (this === obj) ? this.b : 'bye'; }, b: 'hello' }; I can call obj.a with this bound...
I often find it useful to arrange things so that each commit on master's first-parent is a discrete change. It allows git log --first-parent --oneline to be used as a concise, automatically-generat...
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...
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. (...
I agree and I think it should be a separate category, with separate posting rules. There are several examples of how the rules for each category would likely be fundamentally different: Main Q&...
I think we have a UI problem with the "add link" dialog box in the editor: it doesn't capture enter keystrokes which then fall through to the submit button. I'm merrily typing a post when I real...
I'm experimenting with different operators and have a hard time understanding the outcome of certain expressions. I try to combine the ++ operators with other operators such as assignment in the sa...
I have found this nice library for parsing/writing .elf files as output by e.g. the GCC toolchain: ELFIO I have a bare metal embedded project with an ARM Cortex M target. My goal is to overwrite...
Firstly, the technology stack of a commercial project should be selected based on several different decision factors. Staff availability is paramount. The developers, QA and associated team m...
