How do I clone the repository with only part of the history? For example, let's say I want to download only the last 5 commits out of thousands.
Background Many Python programs now recommend installing with pipx, and there is a sense that you shouldn't install with pip anymore, you should use tools like pipx. Main Question However, what ...
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 ...
Hi and welcome to the site. :) I think the idea of a canonical like the one you linked is great. A lot of newbies have too little understanding of their topic to identify common patterns. So they ...
These questions are very helpful to the person asking, and great for driving activity. I think it is good to allow these questions to be asked and to answer them. At the same time, they are not go...
Mathematically, the purpose of a function is to return an output. However, in a programming context functions often have side effects. It is even common to call functions for the side effects alone...
Why does git merge take the source branch rather than the destination branch as a parameter? The most common merge case by far for me is "Okay, this branch looks good, let's merge it into branch X...
When I run pip install foo, pip looks for foo in PyPi. I want it to look for it first in a private repo, let's say pypi.bar.com. Only if foo cannot be found in pypi.bar.com, should pip then look f...
Recently, AI models like ChatGPT have shown themselves capable of generating content and even source code. Just like with human helpers, clear and precise communication is key (especially when aski...
In Python, multiprocessing is easy to do if you follow a "list projection" paradigm. Say you want to take a list of inputs X and apply some function f to every x_i, such that y_i = f(x_i) and the y...
It sounds like you have a Java formatter configured (by default?) and VSC is applying it to your code automatically (on save?). How code is formatted If your only gripe is these specific stylisti...
I want my CLI Python program to schedule a task, and then exit. After some times has passed (say 10 minutes) the task should execute. The task can be a Python method or a shell command, whatever i...
When running various Python scripts, I often need to do this annoying dance: $ python script.py ... ModuleNotFoundError: No module named 'foo' $ pip install foo $ python script.py ... Module...
How are software recommendations handled on https://software.codidact.com/ ? https://outdoors.codidact.com/ has a "gear recommendations" section, so it seems like Codidact is open to the idea. I s...
When I run code . in a directory, Visual Studio Code opens two windows. The first is empty, the second shows directory I was in as expected. I checked ~/.config/VSCode/Workspaces and there is only...
The ideal way is to separate the upstreamable and non-upstreamable changes. For example you could maintain two branches: public and private. All upstreamable changes are cherry picked to public an...
Is it possible for a Python program to send itself in the background? For example, on Linux you can do nohup some_cmd & and any program will run in the background. Some programs also support s...
I know that 1 is sometimes called a pure function - although apparently a pure function must also not vary when the input is constant. By negation, the other kind are called impure functions, alth...
My take on this: Q&A sites used to fill two distinct roles, but only one of these (the more boring one that doesn't matter anyway) is usurped by LLMs. The interesting one is not yet in danger o...
New LLMs like ChatGPT are now creating competition with Q&A sites like Codidact and StackOverflow. Moreover, this is parasitic: LLMs get "boosted" by Q&A sites because they can use them for...
I have a git repository with some submodules. When the submodule repos get new commits on the remote, how can I pull them all?
Create a hash map and precalculate the sort key in it: // Set up: Create mock input let u = ['4', '16', '8', '2', '6']; function expensive_key_fn(x) { console.log("Doing expensive operation...
I don't think the question is trivial. Maven is very complex and confusing at first. The documentation is also quite something. It's not easy to figure out what's going on unless you already know. ...
I think the main reason to do this is when the interfaces fail to account for some subtlety of the contract between caller and implementation. For example, let's pretend for a moment that your use...
You can try to break up the query into CTEs, and then see if any of the individual CTEs are unusually slow. I am guessing the query is not just one select, but probably has subqueries, window func...
