I read posts (e.g., 1, 2, 3) that recommend triggering a CI build process by pushing an empty git commit. I don't understand how this is a good idea as the commit history will be peppered with mea...
Sometimes code needs to assign (or otherwise use) a value that depends on some condition. The naive approach is to use explicit branching, which in Python would look like: if some_condition(): ...
Consider this code example: def example(param=[]): param.append('value') print(param) When example is repeatedly called with an existing list, it repeatedly appends to the list, as ...
A well-known easter egg in Python displays some ideas about writing good Python code, credited to Tim Peters (one of the core developers). This question is about the last: Namespaces are one hon...
I have little to no idea what happens after a client obtains the server's certificate. It has to make sure that it (somehow) valid, but how?
GitHub has a setting wherein they offer to "anonymize" your user email from, say, [email protected] to [email protected]. I presume this is to prevent you from getting spam from ...
I loaded a binary into Ghidra for analysis. The decompiler says undefined8 main(void) { basic_ostream *pbVar1; char *pcVar2; [--snip--] pbVar1 = std::operator<<(pbVar1,"PXZ ");...
In a C implementation in <stdio.h> on Linux I saw something like: extern FILE *__stdinp; extern FILE *__stdoutp; extern FILE *__stderrp; And then: #define stdin __stdinp #define stdou...

I have a website about vacation villa rentals. Around 800 properties are listed. When i start a search, i get properties with my first query which filters type, style, area, no. of rooms, capacity ...
What I would like to do: Set a cell value. Check with a program if cell values conform to data validation rules. I could extract all the information needed to create a validation function, b...
Are any of the popular Excel .NET projects have a functionality similar to Apache POI's DataValidationEvaluator class?
On top of values seemingly coming from nowhere in multiple columns, they also affect each other's behavior: In the GIF below, if the cells in the left column have no value selected, then there is n...
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...
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...
For example, given this function head, this is the hint that is generated: let updateCell workbook sheetIndex rowIndex columnIndex value = // XSSFWorkbook -> int -> int -> int -> stri...
By default Gitlab CI jobs run on any commit. I would like to restrict some of them to run only on commits to specific branches. How to do this in .gitlab-ci.yml?
How to move the main branch back to an earlier commit in git?
Just getting into F#, finally figured out how to add .NET packages to projects, but the way I managed to get it to work doesn't make sense. Once the package is installed (either with nuget or paket...
More specifically: Is there a dedicated docs page listing "properties" that are idiosyncratic to F# .fsproj project files? Why am I asking? Started learning F# a couple of days ago, but just now ...
I've seen macros use parentheses to enclose its arguments. Most of these make sense, as in #define sum(a, b) ((a) + (b)) The outer prevents the following: #define sum_bad(a, b) (a) + (b) ...
I'm writing a library "MyLibrary". In there, I group code into sections that make sense. Let's say I have a folder "Reports" and a folder "Helpers". I would like to have my code separated while ...
Our organization (blindness non-profit in California) is obligated to submit reports to grant organizations (e.g., Department of Rehabilitation) on a regular basis. Most of the time, this means exp...

Found an article about starting a repo with an empty commit. Read the post a couple of times, but still don't understand the reasoning: 1. git log and other commands blow up with terrifying ...
In git you can put your current changes aside for a moment with git stash. This is really neat but what often ends up happening is that you forget what was in there, and what was the state of the b...
I am migrating a WPF app to WinUI3. Things went well until I needed to put a combo box in the datagrid. That MS had removed the datagrid from the standard tools was overcome with Community Toolkit ...

Unlike docker, Podman won't (understandably) use docker hub by default. You can use it explicitly like this: (just using a random example here, it's an OpenAPI linter) podman pull docker.io/dshanl...
