Hi-hello 👋

I enjoy working on really challenging scientific questions that will make a long-term difference.

I provide tech organization/leadership for small teams moving science. Current focus is ML + Bio (more specifically, protein design), but previously I developed a bunch of ML methods for CERN.

You can find my development/ML projects here on github: first of all, check einops (unless you already use it 😏).

Projects I'm interested in

Are you looking for a programming project? I have some ideas for you:

einops support in ruff (upd: Sonar introduced einops check)

Einops is very readable per se, and mistakes are generally easy to detect, but how about making it even simpler with static analysis?

Some examples where it could be useful

python
  rearrange(x, 'b h w c -> b (h w)') # complain on missing c
  rearrange(x, 'b h w 3 -> b (h w) 3') # anonymous axes like 3 are not available in rearrange
  rearrange(x, 'b (h w) c -> b h w c') # complain that either h or w should be provided

einops coloring in vs code (upd: try EinColor for VS code from Marcin Jachmann)

Wouldn't it be great if reduced or added dimension was immediately colored? Something like:

'better' typer  upd: cyclopts only misses autosuggestion to solve this

Tiangolo's typer originally made a number of things right - hierarchy of typers, strict type checking,
and auto-completion for a number of shells out-of-the-box.

That said, typer lacks attention from tiangolo, and lost some critical parts of experience:
- it is slow (500ms for auto suggestion is harsh)
- way many dependencies
- does not handle async functions (fixable)
- it is quite shell-y and not pythonic. I'd like to just call function from shell after all
- strange rules for lists and *args (e.g. can't pass an empty list)
- func(*, kw_only_param, kw_param=False) is not recognized
- func(param1, param2=None) forces to use --param2=val instead of call param1_val param2_val
- ~~type | None not supported~~ (fixed recently)
- dataclasses / pydantic as inputs are not supported
- 'just give me raw input, I'll put it to other bash command' is not supported

That's my complains, but walk over bugtracker of typer to see what's in demand.

unix sockets in SSH-over-HTTP

Do you use SSH? I guess you do, since you're on github.

I've been using unix sockets (UDS) as endpoints for containers for a while now, and it (mostly) rocks.

Several similar containers can live on the same instance, and each mounts a folder with UDS (multiple services usually).
Domain sockets can provide access to various web-servers, and almost anything can serve from UDS.

(If you use TCP port forwarding for containers, try using UDS, you may like it much better, specially if you manage many endpoints or containers!
No security issues, and you can easily add/remove sockets on the fly and without port clashes!
Spice with using symlinks for synonyms, and network management stops being ugly.)

Back to the point: openssh-server does not support serving on unix socket, so I use ugly hack with socat redirecting request to TCP port.
Openssh-client does not support connecting to domain socket (easy to fix this in config though).

While (unmerged) patches are available to support UDS in openssh, I'm on the market for something next-gen,
e.g. something like SSH3 + serving/connecting to unix sockets.

no-std rust barcode scanner   rxing solved it
At some point I've been looking for a barcode scanner that I could embed in web page via WASM,
and from python too.

Nothing was available at that point, but @hschimke kindly added support of WASM target and CLI to his rust project,
and I recommend giving it a try. I could use it on different cell phones right from web page.

interactive playground for einops in jupyterlite

see this issue for details:

Remarks related to all project above

What exactly I am ready to help with (details)

If you think taking one of these projects, I am happy to test your solution, provide detailed user feedback, maybe test in prodiction, and if it works, cover it here or in my blog.
(or einops docs if it is relevant to einops).

Note that doesn't include development, but programming is something enjoyable,
while finding someone interested in using your work is usually non-trivial 🙂.
