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. ...
I did git fetch to quickly get latest commits. I did this instead of git pull so I could deal with merge conflicts offline. But my repository is still stuck on the old commit, and now git pull fail...
In older C and C++ standards, the auto keyword simply meant automatic storage duration. As in the compiler automatically handles where the variable is stored, typically on the stack or in a registe...
I have a Map with Optional values. I want to filter it to remove empty values. Map<K, Optional<T>> input; Map<K, T> result = input. // here is some code I'm looking for ...
Use a static site generator. There are other possibilities, but they seem more complicated or worse for your use case. A static site generator takes in source data in some combination of markup fo...
Usually not in practice, but the user name part of an email address can be case-sensitive. Going way back to RFC821 (emphasis mine): Commands and replies are not case sensitive. That is, a comma...
Sure, I'll step up for this, since nobody else has yet. I think my credentials speak for themselves, but just in case: I'm an accomplished Python developer with a long history of helping people ou...
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...
I am interested in knowing how the recent Codidactyl game and its code were created and obfuscated. See the non-announcement. From other posts, it appears that luap42 and Monica Cellio may have wo...
Method 1: <span> (or other HTML tag) It appears that Markdown isn't detected within HTML tags, so you can wrap the URL-like in a span or other tag and it won't turn into a link. <span>...
I have a post where I mention a script named dead.sh Ok... now I have two posts like that. But that is not a website. It is a filename, and not one reachable through an URL. How can I inhibit aut...
In addition to what Moshi already told you: Among web designers, W3Schools has a somewhat tainted reputation, because it often makes things simpler than they really are. In my experience, this lac...
To start off, here is the complete HTML of a simple example table: <html lang="en-US"> <head> <title>Title</title> <style> table { width: 20em; ...
"Brainfuck" is the name of a programming language; using the full name of the language is perfectly fine. We don't need to bowlderize proper names. As for your other example - foul language in cod...
I just started to see greetings in posts like: "Hello", "Thank you", "Morning" and other types of greetings. Should this greetings be removed from posts or we just keep them? Sometimes I think th...
Caveat When making a decision of such lasting impact, you should conduct your own evaluation according to the criteria that matter to you. This post does not attempt to replace such an evaluation,...
First of all, I realize that this is mostly a library you've implemented while learning programming, for the sake of learning, which is great. So I would rather not put a "wet blanket" over your at...
