Hi HN!

Resource Signal brings reactive async data loading to Python. Main idea: declare what parameters affect your request, and get automatic cancellation, status management, and error handling.

It's inspired by Angular's resource() but adapted for Python's async/await. Works great for APIs, database queries, search—anywhere you fetch data based on changing parameters.

The guide has 5 working examples. Would love feedback!

Is there a best practice how to stream and plot large signal data (e.g. > 1M data points of multiple sine waves) from a Python backend (e.g. numpy + FastAPI) to frontend? My current solution is: fetch ADC data, convert the bytes to base64 and embed it to JSON that will be send to the frontend. Frontend reverses this process and plot it to eCharts.

How else is the data going to make it to your phone?

Oh my, I just looked him up. He is the developer of Virtual Game Station - a PS1 emulator that I used in the past to play PS Isos on my Windows ME PC! What a legend.

Unbelievable

Can't wait to tell my boss, I am drinking coffee because I am waiting for my installs to finish! :)

I find the Nextcloud client really buggy on the Mac, especially the VFS integration. The file syncing is also really slow. I switched back to P2P file syncing via Syncthing and Resilio Sync out of frustration.

This could be used for Captcha systems. Would current bots be able to decipher these?

Yes, you can make ChatGPT decipher this already.

But doing this on a massive scale would warm the planet.

And it's not friendly accessibility-wise.

I think the bounciness of the elements is also a very charming characteristic part of the Liquid Glass UI that Apple introduces. But recreating that is probably very difficult with web technologies.

I am suprised that the Galaxy S25 seems so far ahead in the benchmarks.

I actually like their software offerings like Synology Drive and Synology Moments. Their backup solution also seem to "just work" with Hyper Backup. I'm using a Mac und tried to use Nextcloud, but my conclusion with the Nextcloud Desktop Client is, that it is buggy as hell. Especially the VFS implementation. Synology Drive in opposite just works (for me).

I have a basic Synology DS<something> and like it (for the price). I also use their Android app to stream music and it's not stellar but works I guess.

I'm more shocked by the state of samba in macOS (without additional software). Having to go to the network and manually reconnect to the NAS share every time I come back home is ... poor.

It’s so poor.

To get my mini power up, connect SMB then start some containers I made a horrific Automator app, which runs a script and just tries, sleeps then tries again until my containers can boot and access their data. It’s disgusting. But it works.

The Signals libraries I know of (including reaktiv) are throwing an exception if a dependency cycle is detected in the computation step. But that doesn‘t solve infinite executation loops completely because the user still can define an Effect that updates its (in)direct dependencies - that means User caution is still needed. Angular tried to prevent that in their older versions by not allowing to set other Signals in Effects. But they reverted that decision.
