Suppose I have some code in a file myscript.py like: def my_function(): print("Test") What steps do I need to take in order to make my_function run? That is to say: how do I get Python to ...
C prohibits accessing an array out of bounds even if measures were taken to ensure that what should lie outside those bounds were known: struct MyStruct { int x[2]; int y, z; }; static...
Global variables make the code hard to reason about This is especially visible when debugging. Say you have a function which errors. The stacktrace tells you where the function got it's arguments,...
I remember reading @meriton's comments on that question and thinking they were good feedback; if I hadn't seen them there, I would have written something similar. This is also an argument against ...
Regarding "snark" - it is very hard and subjective to define. Our overall code of conduct says "be nice", but where do you draw the line. On SO, general gruff attitude tends to be treated very diff...
Background I can see the need to use { } when implementing a function-like macro such as this one: #define HCF(code) fprintf(stderr, "halt and catch fire"); exit(code); Because if we use the f...
We rolled out a fairly major update this morning - implementing our new Abilities system. However, it... didn't go as smoothly as planned; the database apparently didn't update properly with new co...
@BruceAlderman gave a good answer with different aspects that covers the most. I'm not very good at SQL, so my answer is more general. When I have to choose between two different things that are e...
#NotABugForOnce This is down to language guessing. If you don't tell the highlighter what language your code is in, it guesses. Sometimes, it guesses wrong, like here. I've edited the post and ad...
I nominate Alexei, who has a body of well-received posts on Q&A and meta, both asking and answering, and seems interested in helping to organize and expand this fledgling community.
For holding ordered sets of keys, there are well-known data structures (the red-black tree, for example) that support O(log(n)) lookup and insertion algorithms. Of course this means that there triv...
I have JSON that looks something like this: {"id":"n-fsdf-6b6", "name":"JohnSmith", "revisionDate":1591072274000} The JSON data is named CharacterInfo. It comes from a static external URL. The str...
Off-topic questions about which tools, frameworks, or technologies to use, unless they are directly related to development (e.g. code, schema changes documentation tools) I propose removing thi...
One of the fonts available (to me) on Google Docs is Caveat. The following is in 18-point Caveat on Google Docs: I found that Caveat is available at https://github.com/googlefonts/caveat/tree/ma...
I am using MediatR in an ASP.NET Core 3.1 application and I want use a generic query and a generic request that deals with getting lists of some standard items I am using in drop-downs and similar:...
These questions boil down to "what are do the people who curate the site want to maintain?" The higher the percentage of people who do that curation (and that includes closing and deleting content ...
JSON is a standard. Performance is implementation specific and dependent on what is being done with the data. The answer really depends on what your environment is. Some languages may have slight p...
How does the community feel about resource requests? For example: I have been working on a project recently. By which I mean: mostly stumbling through by trial-and-error. The particular open source...
How about this for bash: #!/bin/bash echo "What is your web application root?" read web_application_root web_application_root="$(envsubst <<< "$web_application_root")" echo web_...
I want to match standard email syntax (lowercased English, numbers and perhaps also some hyphens and underscores) with regex for a sed operation that matches and changes a single email address insi...
C# language version 8.0 introduces limited support for static methods, operators, etc. in interfaces. However, there are still limitations. I was hoping to use the new language features to try a ge...
One solution would be to catch a more generic base class, like std::exception. If all your exceptions derive from that, you should be safe. Another solution I like better is using destructors to d...
There is no universal accessibility standard for how tall your buttons should be. Consider that when you're using a simple link, users have to click on the text itself to follow the link; as long a...
I was told by my professor/book that computer programs use two kinds of memory and that all variables get allocated either on the stack or on the heap. Is this true? How can I tell where a variable...
This is a small bug (cosmetic) that I have noticed while adding some code in a post: I have artificially added some whitespace here and there, otherwise the line would have been way longer.
