This is a rather vague question, but I'm trying to solve a specific problem and I'm inexperienced in most of the potential solutions, so please forgive the inherent ambiguity. I have access to a d...
If you've poked around the mod tools here a bit, you may have noticed that QPixel has an impersonation feature, live on prod. It's there for much the same reasons: so that developers can test and i...
‘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...
Yo. Me here. I used the code for the Codidactyl on the run as basis for the game, added a wrapper checking for the Konami-code by being a simple finite automaton and after that creating the canvas...
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...
A recent flag for this question suggested that it would be a better fit for the Linux community. There is no motivation provided, but I guess it is related to the fact that most of the question and...
First of all, let's understand why your regex didn't work. The first part is \w+\.\s, which is "one or more alpha-numeric characters" (\w+), followed by a dot and a space (\.\s). If the regex was ...
In Bash, IFS is an internal variable and it stands for "Internal Field Separator" <- according to this link, it "determines how Bash recognizes fields, or word boundaries, when it interprets cha...
As you have worded it, for most open source project, particularly small ones, I would say "yes", it is "wrong" to demand features. Or rather, it's extremely rude. Most of the time open source soft...
I think these kinds of questions are fine, but I am just one person. open source product I have been using appears to be poorly-documented is an extremely common problem. I have actually seen the p...
SIGSEGV is defined in the C header signal.h. To generate the signal, it should be sufficient to just do raise(SIGSEGV);. As far as I know, this is well-defined behavior.
It is possible to create a new formatter class by subclassing string.Formatter class and then to use it like myformatter.format("{foo:customformat}", foo=foo). It's not super-convenient though, and...
To whether the tag is useful: no. It's useful for tagging people ("this person does frontend and backend") but not questions. I don't see the point of adding "do not use": just delete the tag, whi...
Speaking personally (not as a Codidact admin): One low-key way to promote this community there is to cite it in answers. If you see a question there that you want to answer, see if it's here too....
This can depend on both your flavor of SQL and your personal preference - I've seen a number of schemes in use. For MySQL, the most common scheme I've seen used (and the scheme that my editor uses ...
As we start on building a new community here together, we're bound to find some sticking points. Those might be bugs, new features you need, things you need support with... whatever they are, the C...
When I want to print a number or a string, I can use f-strings (Python >= 3.6) or str.format, and I can use just the variable between braces, or use format specifiers. Ex: num, text = 10, 'abc' ...
The sole purpose of the do { } while(0) is to write macros that accommodates to all manner of diverse coding styles. It is quite common not to use braces after if statements, so this is a common co...
In git I branched feature-A from master. To reduce eventual merge conflicts later, I branched feature-B, which heavily overlaps and depends on A, from feature-A. A build of the feature-B branch s...
This is meant as a FAQ Q&A regarding variable-length arrays (VLA). The two bugs described below are surprisingly common. I'm trying to use the variable-length arrays feature of C99 (and newe...
I am working on a website which unfortunately uses a mix of linked and inline CSS and Javascript (and, even more unfortunately, I can't do a lot about the use of inline CSS and Javascript), and am ...
Some variables make sense to bundle together. For example, if you have a graphics method to draw an image, you will need to pass in an X and Y coordinate for where to draw the image. Those are two...
what ways can I get a string's length in D? There are many different ways, and that will depend on the content of the strings, their types, and how you define the terms "character" and "length...
Does Inteheritance actually meant return and Polymorphism meant to print out values? This doesn't make the slightest sense... Probably you should forget all you've heard - don't "watch tutoria...
1st issue As others have said, echo "$array" only prints the first element of the array; I suggest printf '%s\n' "${array[@]}" to print each element on a line. 2nd issue More importantly, th...
