Is it possible to "stream" :gitannex: #gitAnnex files? Like: I want to get the first few lines of that 10Gb CSV file but don't have the diskbspace to fully download it. E.g.:
> git annex cat myfile.csv | head
A workaround is to interrupt a `git annex get` shortly after launch, but it might not even allow getting the file when low on disk space, right? 🤔

😩 Man, why does #make not have an option to build only files matching a pattern (no, globbing doesn't work, the files don't exist yet) or at least an option to list all the files it would build (no, make -n does not help and is not well parseable).

@npub1zxa…4nk0 Not the build. The app in runtime.

😮‍💨 sigh... So :nixos: #NixOS really has no nice mechanism to *both*:
· declaratively specify wireless networks (works with networking.wireless, but not with networking.networkmanager)
· run scripts after e.g. network connection is up (works with networkmanager.dispatcherScripts, but no built-in way with wpa_supplicant - wpa_cli -a actions-script seems to be it but has be be manually fiddled with)

@npub1shg…y3ry I know. But good luck with a 'pacman -Syu' on mobile wifi on a train. It was worth a try - and suceeded, which is why I was surprised.

2024-04-03 12:23:17

Interesting that you just update #Thunderbird on #Manjaro with 'pacman -Sy thunderbird' and it still works. Normally partial upgrades like that are a ticket to brokenness on #archlinux + derivatives.

Someone made another easily movable #HoneycombStorageWall insert ('quickfix' [2]) that looks an awful lot like my #Screwiverse [1] design approach. They put it under a locked-down license and didn't make it a remix of the original HSW (which would also require a slightly more open license).

@npub1hg2…k372 No, it wouldn't use the info, but that's just a matter of implementation.
You can put any info into git annex metadata, e.g.:
git annex metadata --set artist=DaftPunk --set album=RAM -t cool -t chill -t pop those/files/with/daftpunk
You can then use views to have git annex make a new branch with artist/album structure:
git annex view artist='*' album='*'
Or just folders named like the tags:
git annex view tag='*'
And much more. It's quite cool!

:gitannex: #gitAnnex's built-in file deduplicationis is not only useful to save disk space, but also to catch certain errors in your data pipeline:
If after several days of data processing and producing new files from others, git-annex says everything is already synced up, it's an indication that you messed up - like hard-coding the input file path in the script 🤦 😑 😅

@npub1sgc…ulhx Preprinting works as well, sure. But that's another step and slows it down, so I tried this one. I tried with the supports, but it's really hard to get right...

I chose a kinda print-in-place approach:
The print is paused right before the case is closed, then the moving part is manually removed from the bed with a little snap-off helper lid at the side put into the case. This works much more reliably than anything I tried with glueing or closing the case otherwise or trying to to actual print in place (failed miserably 😅).
A drop of e.g. silicone oil and the operation is very smooth!

I finally made it: an XOR mechanism that requires exactly one of two keys to be inserted at a time. I call it the 🗝️ #keyguardian.
This is very useful for example to track where important small things go: Want to take the car keys? You have to insert your name tag so unlock it.
I made it with #SolveSpace and I'll put everything on #Printables soon. 😊

I think it's amazing how you can get from nothing to a fully parametric #STL of a toy screwdriver in eight lines of #Python code with #sdfCAD.
If I had tried the same in a graphical #CAD software, it'd probably taken me ages. Also, none of the buttery smooth curves the #sdf - based approach makes so easy.

@npub15lj…pccu Thanks. This is not about circumventing the locking, but if I develop a flake, push it, then try it from somewhere else with nix run, it's weird and annoying that is uses an outdated, cached version instead of fetching again.

2023-11-23 11:02:37

I very often have to 'rm -rf ~/.cache/nix' so I can continue working with 'nix flake ...'. Either it's weird errors that some path in /nix/store/... is not found or it does not use update the flake from the specified url but uses an old version.
I'm sure there is a better way than manually nuking the cache? 🤔

#latexmk is great for auto-compiling your documents.
However, it fails in some cases and I'm currently bitten by a nasty one:
- \includgraphics'ed PDF is corrupt (It's a missing, unlocked #gitAnnex/@datalad file)
- that stops biblatex from properly finishing the .bcf XML file
- *before* fetching the missing PDF (with #DataLad), latexmk runs biber on the now corrupt .bcf (fails and deletes the .bbl)
- vicious cycle repeats literally forever - latexmk is in an endless loop 🙄

TIL that apparently @npub1uwa…z36q can be controlled entirely from Python. The Python console that shows exactly what you're doing in the GUI is absolutely sick!
So can one replay a workflow from start to finish? Does that make a FreeCAD design version-controllable? Can the Python code be streamed to file?
Very exciting! (I have never used FreeCAD before)

I am unsure whether to learn :rust: #Rust or :haskell: #Haskell next. (Not that I have time to, but one may dream, right? 😉).
Knowing Haskell would allow me to contribute to some software I deeply care about (#hledger, :gitannex: #gitAnnex). Rust on the other hand looks *much* easier to get going with coming from #Python (and embedded #C / #Cpp). Its cargo toolchain and ecosystem also looks nicer, plus easier availability on all architectures (aarch64!).

@npub1hg2…k372 Yeah good old rsnapshot. A pity that renamed or moved files are not deduplicated... borg is so much more efficient at this.

2023-08-13 11:14:17

- reply

@npub1hg2…k372 Hm. A bit flip in something like a borg backup could surely have more devastating consequences and potentially cause more than one file being broken, right? #GitAnnex can at least do something about bit flips (auto-get or tell you where to get it from), fancy backup systems will just choke, won't they? 🤔

2023-08-13 10:56:55

- reply

@npub1hg2…k372 I wonder why :gitannex: #gitAnnex is not considered to be a backup system¹. I use it as such always have one or more remotes that retain everything. Restoring a broken local repo is then a matter of cloning from those remotes, done. If that is not a backup system, I don't understand what is 😅

But how did that happen? A file in .git/annex/objects broke on your machine due to hardware failure?
