i did not realize how fragile "sd card plugged into raspberry pi" is. my headmate's 3d printer server just... had an sd card die. it sort of reads except sometimes it spends half a minute reading a single sector

wtf

it’s honestly kind of baffling discord has never been seriously slapped for GDPR noncompliance

here’s what deleting your account does:

• it locks you out
• it removes your avatar and username and profile content

here’s what it doesn’t do:

• delete public or private messages
• delete other people’s notes of you
• make the API retroactively censor message metadata like user ID

so basically if you want things deleted, break TOS and do it yourself (you won’t get everything) 🦋

Imports in Python can be confusing.

I just saw someone ask "why do I have to prepend a dot to import a file in the same directory?"

That depends on whether the file with the import statement is in a package or not.

But, whether Python considers it to be in a package depends on how you imported (or ran) that file. You can't determine it from the file's content or the filesystem structure!

Check alt text (image description) for explanations of the examples.

#Python #import

Running four commands from the parent directory. "python3 mypkg/abs_import.py" prints "in pkg", because Python found mymod.py in the same directory as the file it has been asked to run. That's because sys.path (which is used to define search order for modules) is initialized like this (quoting from the docs): "The first entry in the module search path is the directory that contains the input script, if there is one. Otherwise, the first entry is the current directory, which is the case when executing the interactive shell, a -c command, or -m module." "python3 mypkg/rel_import.py" throws an ImportError: "attempted relative import with no known parent package". Just because you're running a file in a subdirectory doesn't make this directory a package. "python3 -m mypkg.rel_import" prints "in pkg", because Python is now interpreting mypkg as a package name, has found the rel_import module in that package, and is able to do relative imports from there. "python3 -m mypkg.abs_import" prints "top level". Remember the documentation from above: If there is no input script (and there isn't, we're asking Python to resolve and run a module instead), sys.path will first look in the current directory, i.e. the one containing the mypkg package, because that's the one we're currently in.
We now change into the mypkg directory with a "cd" command. "python3 abs_import.py" prints "in pkg", because Python is going to look for "mymod" in the directory containing the input script (which happens to be the current directory, but that's not relevant). "python3 rel_import.py" throws an ImportError "attempted relative import with no known parent package" again. Understandably, because Python has no way of knowing that the directory we're currently in can be interpreted as a package. "python3 -m abs_import" prints "in pkg", because sys.path first looks for mymod the current directory. "python3 -m rel_import" raises an ImportError "attempted relative import with no known parent package" again. That's because, in contrast to what we did in the last example in the previous screenshot, we're now just using "rel_import" as the module name we're asking Python to run, without the "mypkg" prefix. Adding the prefix wouldn't work, because our current directory is already inside the mypkg package and Python (correctly) wouldn't find another "mypkg" directory in it. But without the prefix, Python doesn't know that the "rel_import" module resides in a package at all.
We now move into the parent directory again ("cd ..") and delete the top-level mymod.py file. Then, we attempt the examples from the second image again. "python3 mypkg/abs_import.py" prints "in pkg" as before, because Python found mymod.py in the same directory as the file it has been asked to run. "python3 mypkg/rel_import.py" throws an ImportError: "attempted relative import with no known parent package", just like before, because it interprets the file path as a script to run, not as a module in a package. "python3 -m mypkg.rel_import" prints "in pkg", just like before, because Python is interpreting mypkg as a package name, has found the rel_import module in that package, and is able to do relative imports from there. "python3 -m mypkg.abs_import" throws a ModuleNotFoundError "no module named 'mymod'. Before, it printed "top level", but now we have deleted the top-level mymod.py file that it was importing.

Ugh, so in one of the replies to my experiments with #BorgBackup and associated tooling, @guerda asked "well, why not #restic?" and turns out, my main reasons against using restic (no compression and no exclude exceptions) are no longer valid, so I'm currently re-evaluating it.

Almost finished my writeup. And you know what? Both are really good.

My decision might boil down to performance against remote hosts and SSH vs SFTP, and whether "rclone serve restic" can save the day there.

#Linux #CLI users! I'm curious how many of us are using "modern", "enhanced", "reimagined" versions of classic command-line tools. Think bat instead of cat, rg instead of grep, exa instead of ls.

If you don't use them, why? Is the installation overhead too much, e.g. because you're using a lot of machines? Does your brain need to stay compatible with the standard tools for some reason?

Feel free to write a reply, the poll can't possibly cover everything :)

wondering how healthy it is for our bulk storage cluster to be running databases. maybe we should add an SSD or two. ⚙️

got a Normal USB cable

it claims to do 100 W. don't think i would trust the flimsy piece of FR4 that forms both mechanical and electrical bits of the rotating joint on the left with 5 amps but thats just me

(there are two rotating joints in this cable. one rotates 360 deg and is disassembled. the other rotates about 180 deg and is integrated into the molded plug)

i've read a lot of blog posts about it, participated in a lot of arguments, but do you want to know the two things that actually made me a better (open source software/hardware) developer?

1. experience
2. not being in precarious situations where my living situation and to a lesser extent income feels like, or can, evaporate at any time, and not constantly being in the black-and-white states of mind that inevitably result from it
