I live in Prague and seeing the temperatures expected during weekend, I bought at least the portable AC. I'd say 2-4 weeks is quite a long period to justify this purchase.

Yes, historically, the AC didn't make sense in Prague, but there's no going back, the world is just going to get hotter.

Yeah, the focus is mostly on night trains, although some day combinations leak to the data, so it's possible you'll find some combinations for daily trains.

Of course, I'd like to have the daily trains in the data, but that would drastically increase the number of combinations and require some more scaling of the scraping, which I don't want to do at this point. Focusing on night trains only is a nice niche.

I plan to add at least some daily trains between core cities, e.g. the EuroStar London <-> Paris route, which would make multi-leg search to farther cities easier (i.e. combination of night train + daily train).

It's definitely similar, but the philosophy seems different. NightRide supports exactly the use case on searching a route on a specific date. I also noticed that if they don't have the price pre-scraped, a scrape is called dynamically on user's request.

My idea is to pre-scrape the prices and answer questions such as: wanna go to Amsterdam for a weekend? -> here are the best dates and prices.

I have a working version of Trenitalia scraper (Intercity Notte trains across Italy), I just haven't added the routes to UI before verifying it works reliably. Hopefully I'll add it in the evening.

Also the Milan - Brusells route from European Sleeper, it's scraped but not yet in UI. I'll reply here when it's done.

That's the Prague - Zurich NightJet that's hellishly expensive, possibly because the target audience are Swiss people for whom it's not so much :D Also, NightJet does not price very dynamically as opposed to other providers, and their baseline price is always quite high.

But yes, in most cases this journey will be more expensive that an alternative flight, which is a shame. However, there are routes where it's comparable, e.g. the Prague - Amsterdam route.

European night trains search engine. The plan is not to provide the functionality where user searches for a specific route on a specific date and the engine returns prices. The plan is to provide "tips for trips", e.g. I provide a starting city and it will recommend me interesting trip ideas any time in the future. There are many flight apps that provide this functionality, but no train app.

Currently I'm building scrapers for all relevant provider, then I want to connect the data for multi-city trips recommendation. Plus some connection to the day trains so that the trips are built more easily.

Some existing trip recommendations:

Prague <-> Amsterdam https://trainbot.eu/?from=prague&to=amsterdam&type=return

Berlin <-> Paris https://trainbot.eu/?from=berlin&to=paris&type=return

Zurich <-> Budapest https://trainbot.eu/?from=zurich&to=budapest&type=return

For me personally, I have the basic Claude Code subscription that I use to rewind on some evenings or on weekend, to code a bit for 1-2 hours. I have like 3-5 session with it every week.

The 5h windows are frustrating because I can go through them quickly if I have a more complex task. I haven't yet met the weekly limit. I'd say there are many cases similar to mine.

I agree, their autocomplete (tab) model is the best, but recently I realised I am using it less and less - the new models are so good that I mostly just do agentic coding, and I do very little changes in the codebase by myself. This is probably a general trend and if the usage of autocomplete models is dying out, it's understandable the companies are not investing resources into it.

That has been true for some time now, definitely since Claude 3 release two years ago.

I wonder when we will see an LLM deployed directly in a space rover on a mission like this. The time savings could be huge.

I usually love names by Mistral (Mixtral, Ministral, Pixstral) but this one just sucks. Not sure about Clistral though :D

It's not just you, I hear this often, but I am always suprised people can read for so long in bed. No matter how interesting a book is, I can rarely read more than 20-30 minutes before the urge to fall asleep becomes too strong.

But I can sometimes code until like 4AM. Weird.

Funny coincidence, these are the exact sci-fi books I read this and previous year, in the exact order I read them (I read some non-sci-fi books in between to not get overwhelmed). I finished Project Hail Mary literally one hour ago. All the books were great, but Remembrance of Earth's Past series was literally life-changing, truly a masterpiece.

I'm guessing you plan to read Dune next? ;) I plan to start with it during Christmas break.

This is my experience as well. Mistral models may not be the best according to benchmarks and I don't use them for personal chats or coding, but for simple tasks with pre-defined scope (such as categorization, summarization, etc.) they are the option I choose. I use mistral-small with batch API and it's probably the best cost-efficient option out there.

Is it because the model is not good enough at following the prompt, or because the prompt is unclear?

Something similar has been the case with text models. People write vague instructions and are dissatisfied when the model does not correctly guess their intentions. With image models it's even harder for model to guess it right without enough details.
