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.

In C#, I have two lists and need to mark records in the first based on the second. Here's a sample: public class Vehicle { public string Make { get; set; } public string VIN { get; set;...
Is uint8_t guaranteed to be a character type if it exists? Will using a uint8_t* to examine bytes of an object cause violation of the strict aliasing rule? Is the following legal code: #include &l...
Consider an object for which a method is invoked. Beyond certain point the method no longer accesses this at all. No read/writes of non-static members. No invocation of non-static methods. Is it ...
No, such an operation is not safe. The documentation of std::unique_lock in the standard states that it's UB for the mutex do be destroyed while the lock still has a pointer to it. However, there ...
tl;dr: Allowing beginner-level "help me diagnose this" questions will generate large volumes of duplicates if the site ever scales. We need to think about how to structure things if we want them. ...
Historically, compiling programs could take a long time. Interpreted languages did not need to be compiled. So if developers wanted to change the program, if it was interpreted they could just twea...
I have developed an Atom package which calls SyncTeX (a utility for reverse lookup for LaTeX), and then opens in Atom the file specified in the SyncTeX response. I'm developing on Linux, but now a ...
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...
When we launched this community, we did not yet have the ability to set different reputation grants for different categories. We've had this for a while but we failed to follow up before now, sorr...
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...
Note: I asked this question on TopAnswers a couple weeks ago, but didn't get any response, so I figured I'd ask it here. I am currently learning C++. I have a parent class (Vehicle) and two subc...
Is it valid to partly allocate an object, as long as you only use the allocated part of it? #include <stdio.h> #include <stdlib.h> struct s { int i[100]; }; int main(void) {...
You want to scale from one linear range to another. That can always be done with y = mx + b where X is the input value and Y the output value. M is the scale factor, and B the offset. You ...
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...
For what it's worth, I have some 20 years of experience designing embedded C systems, with large and small code bases both. Code design is some of the hardest things to do, since books about object...
grep is not the right tool for your case. You can use basename: basename a/b/c --> c basename a/b/c/ --> c or, in your case basename branches/features/arm_and_musl --> arm_...
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...
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 ...
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...
