‘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...
From simple subtyping concerns, you want the arguments of your methods to be as abstract/imprecise as possible while still allowing you to efficiently accomplish your goals. This allows your method...
What does it mean that we can use memcmp(3) on invalid values? ISO C allows comparing an invalid value through memcmp(3), because it doesn't read the value, but rather its representation, and "rea...
There are many ways to do it, it depends on what data you already have and/or the Java version. I have only the year's numeric value If you already have a value as a number (int or long), and i...
It is, as you said, an operator so it doesn't make any sense to place a comma somewhere between the operator and the two operands. The first operand is the template string, and the second operand ...
Would it discourage others from posting answers, if they saw that a question had an answer with a "works for me" indication applied immediately? (More so than just seeing an immediate, comprehensiv...
Before attempting this, make sure it makes sense in context. In a few particular situations, it would be better to take a different approach rather than using the normal tools for composing or f...
It's because of this rule: *{ background: rgb(3, 28, 87); } That applies the darker blue background to every element individually, and that isn't overridden when you change the background o...
I respect Alexei for opening a discussion on this, and Lundin for providing hard-won real world experience. I would like to put in a "pro", on the grounds that "I read this book and I'm a better p...
Grouping related items into modules is of course generally good practice, but it serves a practical purpose as well. The important part here is the #[cfg(test)] annotation. The #[cfg(test)] anno...
Between-lines relations are not easy to look for with grep, which is a line filter. You could use a regex that spans lines, but I find this annoying because of all the flags you have to set. Grep ...
I have text (xml actually) files. Some files contain 'foo', some contain 'bar', some contain neither and some contain both. It's the both I'm interested in. How do I do an AND search on words in...
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...
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; ...
