Can you recommend any kits? Out sounds like an extremely fun hobby.

A fully local Retrieval-Augmented Generation (RAG) implementation for querying 25 years of Swiss Teletext news (~500k articles in German language) - based on Deepmind's most recent Gemma model.Why? I thought it's a cool type of dataset (short/high density news summaries) to test some local RAG approaches. Gemma 4 gives some impressive results, but could probably use some more tweaking on the...

Please don't. The project is around since at least 2022.
Spending years on a cool project, and than some dude posts such a comment...
You can use an IDE like IntelliJ and you get syntax highlighting, code completion etc.

I built TeletextSignals, a local RAG + LLM experiment over ~25 years of Swiss teletext news in German-language.Teletext is a TV broadcast system that delivers highly concise, space-constrained news texts. That conciseness turns out to be a real advantage for semantic search and retrieval: dense information, little fluff, and consistent structure over decades.The project runs fully offline and...
I think it can be more efficient for two-step RAG so you can reuse the natural language query directly, but for agentic RAG it might indeed be overkill.
I was just working on a RAG implementation for >500k news articles, completely local, using postgres as a vector database:
https://github.com/r-follador/TeletextSignalsI'm positively surprised on how well it works, especially if you also connect it to an LLM.
Also, depending on the ingredient, it makes more sense to use cups as a measurement of volume, not mass, when converting to metric. E.g. liquids, yoghurt etc.
Another thing: although not strictly metric, but European recipes also use tablespoon and teaspoon as measurements for smaller volumes, so no need to convert this.
Just my two cents, other than that very nice work!!
Depends: for hobby purposes, or what my daytime job forces on me?
Extremely tight results and the majority of cantons voted against it.
I still believe it's the way forward.
As a hobby project, I was looking into using LiDAR data to view archeological points of interest in Switzerland:
https://github.com/r-follador/delta-reliefIt would be interesting to overlay TESSERA data there, although the resolution is of course very different.
How do you use it with Jetbrains? Junie? Or just as a separate CLI session?
This argument is not limited to gene therapies, but would apply to pretty much every pharmaceutical product.
One issue is however that the actual costs are not so much in early R&D (what the publicly funded universities and hospitals are doing), but in the later stage (clinical trials) which needs deep pockets and appetite for risk, which only big pharma has, because they see a potential big payout.
SwissTopo has a separate dataset of buildings and structures in Switzerland, so they basically just subtract it from the LiDAR data.
I think the examples should make it more clear. Thanks to the high resolution of the data, you can see subtle changes in the slope (aka relief aka microtopography) that could hint to underlying remains of human settlements (usually some suspicious geometric patterns that you would not expect in a natural terrain).

How do you suggest to change the description to make it less confusing?

I can't get it to work, but it sounds interesting. Does anyone have a screen recording to share?
Do you have any links further elaborating this?
Any recommendations regarding freight forwarders?
Hijacking this thread: what's currently the cheapest way to get structured data out of a PDF?
I assume there's some reasonable tool out there to convert PDFs to Markup and than feed it to some LLM API with okay costs (Gemini? DeepSeek?). Any suggestions?
Fighter jets emit ADS-B? I know it's only training, but I'm curious?
So in "Paskalampi" and "Vesijärvi", which part of it means "lake"? Naively (I have obviously no clue about finnish), I would have expected some syllables (or token in modern LLM terminology) to occur in both names (i.e. representing the "lake" part).
