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.

As we have set up communities here on the Codidact network we've been appointing temporary moderators. Usually some people stand out from the proposal process and early activity. Ultimately, of c...
These two uses of if are different The if at the end of a list comprehension syntax: [num for num in hand if num != 11] is a filter; its purpose is to decide whether or not the resulting list ...
My actual motivation is to understand the semantics of the .gitignore file syntax in precise detail, for a program which is expected to emulate them as accurately as possible. However, while coming...
Git's interactive mode has a patch action. This is the shortcut for it: git add --patch <file> It will split the file into hunks and interactively ask which one's to add. It has a plethor...
Disclaimer: I am not a security expert nor a security professional. There is, of course, a relevant XKCD comic for this: The entropy numbers appear to be accurate based on this security.stackex...
RFC 3986 defines a suffix reference as follows (emphasis my own): 4.5. Suffix Reference The URI syntax is designed for unambiguous reference to resources and extensibility via the URI scheme. ...
How do I delete contents of a specific field, if it matches a pattern, and there is nothing else in the field? I have a several GB tsv file, and I am interested in a specific field (72). If it cont...
As @Quasímodo has shown, the search pattern \(abc.*\)\@<!bird\|bird\(.*xyz\)\@! solves your problem. But, why does it work, and why does your original approach not work? What you want to achi...
Assume this trivial logic puzzle which I have made up: There are three boys, Fred, John and Max. No two of the boys have the same age. Max is older than John. Fred is not the oldest one. Quest...
Given the link where the code comes from (based on your other question), this is just a, let's say, "free-form/pseudo-code/documentation example". It's not a valid JavaScript code. It's more like...
Since accessing the memory allocated by malloc beyond the size given to the call is undefined behaviour (which means that the standard poses no restriction to the behaviour of a program that does t...
By "deeply clone", I assume you mean "also make copies of whatever nested structures the object might have". And for those, I guess libraries like Lodash are more reliable and appropriate if you wa...
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...
Co I'm a database/desktop dev venturing into programming web apps using Angular and I've been informed 'functional reactive programming' is something I should be aware of. Some other site has a ge...
Currently, there is no consensus about whether to provide tooltips for the voting buttons (especially the downvote one). However, the community now includes quite a lot of questions that attracted ...
Statements and expressions are two syntactic categories that are used by many programming languages. Since they are syntactic, they depend on the programming language's syntax. In a real sense, a s...
This isn't specific to git merge. The standard Git behaviour is that any content- or history-changing command operates on the current branch. For example, you cannot git commit to a branch other th...
Regarding undefined behavior/uninitialized variables of automatic storage duration First of all there's some misconceptions here. if (x == 0) is UB only because x was declared as a local variable...
Functions in C have external linkage by default. In other words, the storage class specifier extern is applied to functions by default, with the effect that they are visible to all translation unit...
No. Software Development is about writing software. Yes, you can stretch almost anything that is an input to software to be "writing software". But arguably the closest analogue in actual Software ...
Indeed, the $HOME/.application-name is the old way. Doing that nowadays is frowned upon (this is an example of what happens if you try), mostly because, as you said, it clutters the home directory....
As a relative newcomer to Rust, I'm trying to understand the behaviour of lifetimes, but I am confused by the following code: let s: &str = "first"; let mut r: &str = s; println!("First ...
The Python Global Interpreter Lock (GIL) is a mutex in the primary Python implementation (CPython) that is acquired whenever Python (byte)code is executing. This means within a single (OS) process ...
tl;dr, the lifetime of "second" is static The heart of your confusion is this: Since we are taking a long-lived reference r to a string slice inner which is destroyed at the end of its scope, ...
As other answers have said, we have some of these, they're helpful, and they can be hard to write. On Codidact there's another option, should the community want to enable it: articles. An article...
