There's one for the Czech network (one of the densest in the world, if not the densest) https://grapp.spravazeleznic.cz

Please do run this on your own workloads! It's fairly easy to set up and run. I tried it a few weeks ago against a large test suite and saw huge perf benefits, but also found a mem…

Read my posts again, I'm not complaining it's not for the masses, I know it isn't. I'm complaining that it's being forced upon people when there are simpler alternatives that help …

I find it much more beneficial to lower the barrier for entry (oftentimes without any sacrifices) instead of spending time and money on upskilling everyone, just because I like eng…

Fun aside - I actually used polars for a bit - first time I tried it, I actually thought it was broken, because it finished processing so quickly I thought it silently exited or so…

I was talking about data engineering, because that was my job and all analysts were downstream of me. And I could see them struggle with handling infrastructure and way too many to…

As a user? No, I don't have to choose. What I'm saying is that analysts (who this Polars Cloud targets, just like Coiled or Databricks) shouldn't worry about instance types, shuffl…

Having done a bit of data engineering in my day, I'm growing more and more allergic to the DataFrame API (which I used 24/7 for years). From what I've seen over the past ~10 years,…

For those not familiar with this kind of computing challenges, I must link this wonderful video about TypeScript types running... DOOM. https://www.youtube.com/watch?v=0mCsluv5FXA

Whoa, I've been battling with an issue where my new M4 Mac Mini, disconnected from all peripherals, just sips power and gets rather warm overnight. Cools itself when I wake it up. …

I remember just adding one letter to the instance type in EMR to switch from Intel to ARM... and saw a 20% speedup as well as additional 20% hourly cost saving, all in all 1/3 cost…

Note that this already exists on top of SQLite proper - authored by Ben Johnson (Litestream, Fly.io etc.) - https://github.com/benbjohnson/postlite

I encourage anyone to study these protocols, they are sometimes a lot more prevalent than one might think. Take the Postgres wire protocol, it's supported by a number of databases …

For me the main deterrent from Gitea has been their approach to UI design. The shameless inspiration (if you can call it that) they took from Github is pretty startling, the two in…

Anyone can share their experience with the somewhat new STRICT mode? Does it help? I tend to use Postgres when available, primarily for the added strictness, but I'd surely prefer …

It's wonderful tool and has simplified workflows for many, just be mindful of its one giant security implication. Should your database credentials ever leak in any way (lost/stolen…

We used to run it self hosted, but the architecture is rather complex, so we ended up switching to their SaaS offering. I tried advocating [0] for a leaner architecture for simpler…

There are several principles that have helped me: - Do NOT migrate to new tools, even if they are really shiny and popular - this may end up being a big hurdle you'll regret down t…

Clicking on the link I though "I wonder it it starts with time.sleep" It was a pretty safe guess, though, the number of bugs related to this is pretty epic.

Perhaps I'm mistaken, but from an interview with the game author, I gathered that you can use 10k+ words, only ~2300 of those being candidates for the winning word. But the analysi…

What I find hilarious is that companies argue who can query 100 TB faster and try to sell this to people. I've been on the receiving end of offers by both of the companies in quest…

I remember benchmarking fast compression algorithms a while back and had lz4 as one of the top contenders, but I remember going with Snappy over lz4, because I ran into some compat…

That being said, I now remember I stopped contributing for a slightly different reason. While I tried to fill WD with complete information about a given subject, this was never lev…

It’s fairly difficult from the other side as well - contributing. I’ve been trying to complete wikidata from a few open source datasets I am intensly familiar with… and it’s been r…

Nice. Reminds me of an optimisation trick from a while ago: I remember being bottlenecked by one of these trigonometric functions years ago when working with a probabilistic data s…
