I know. And by now I know that very well. Like someone-screaming-in-my-ears-know. I am starting to think that Polars is showing all the signs of a hype or a cult. I am still not convinced, particularly since the community feels more like a

Do you use it over many machines (RAMs)? I dont care so much about the memory and CPU stuff, I mostly leave the heavy lifting to an SQL engine. Although the Null handling seems very compelling, I guess it comes at a cost of incompatibility

What is the difference, other than parallel execution?

Jupyter is a decent REPL. I use it when I want to try a new language. Or when solving adventofcode. If I had the desire to learn Ruby, i would probably start by downloading a docker image of jupyter with a Ruby kernel.

One reason SQL has become more popular lately is as an API for map/reduce. Before you would write a Java/c++ class that would do the map/reduce job for you distributed over 100s of CPUS. And you would feel like you were on th

Ok, I'll guess I'll double-down since I am getting downvotes and it is still on topic. I would be proud of someone said that about me. I have introduced new technologies (that work well) but I have also spent a significant amount

You are right. And I am mostly a "T" guy so I guess the answer was mostly about the transform. For extracting the data, go is probably a very good choice. But for transforming, pretty often not, although your use case may be suita

Thank you for sharing your experience and I am sure it is right for you. And I agree that Scala can be too much. I just wanted to point out that there is a fundamental reason that for loops are inferior to map/reduce when working with

What is current language and have considered doing it in SQL? I don't think go will be the right choice. It is just not its strength.

by fifilura 2y ago
Where I feel go is lacking is for data wrangling. Group by, filter, map, join. It is just very error prone, inconvenient and slow to implement with for loops.

Exactly, and same as my comment below (parquet+iceberg+s3). And yes Athena is a part of that. And we also use dbt but mostly for a place to commit and push queries. And I agree with the other question about glue, it is the ugliest part. I g

Parquet+iceberg stored on s3 as a base. That is solid enough. After that comes various kinds of caches, maybe postgres for frontend? Or something streaming? But once everything is stored as files you gain the freedom to experiment or refact

Around that time, and probably for that reason, Opera was ported to BeOS. https://www.wired.com/1998/08/opera-browses-beos/

In Sweden there is also a closed down reactor close to the Stockholm city center at the technical university (KTH). https://en.wikipedia.org/wiki/R1_(nuclear_reactor) Not the same as the Ågesta reactor, which is mapped

In Scandinavia i would say Denmark is the anomaly. Their bet is on wind power. I think they also had a negative sentiment towards nuclear because Sweden built one of their (now closed) plants very close to Copenhagen. Norway has so much hig

To be fair, I don't think TFA is written to be taken seriously. It is more like a comedians roast. But still, it reminds a lot of rumours without base that spread over e.g. twitter. For example of presidential candidates.

It is always possible to trash-talk people who actually do things. Sure the brits in general were full of self-confidence and stiff upper lips and lacked competence, but that includes most of them. Scurvy was not well understood at the time

Nuclear power needs massive amounts of cooling so they are most often built close to the sea, or at least a major river.

I can not read the article, but maybe this was by design. They expected the telephone boxes to be more resilient than building a custom system. Either way - what did the V bomber program cost?

Yeah, my question was mostly out of curiosity. At some point someone must have approved this project and the costs coming with it. One answer could be the military with endlessly deep pockets. My point is that it should have been easy to ju

Why do they use trains to move the rods around? Are there actually places in Britain where it is not possible to move them by shipping. It seems like a high cost to introduce a new way of transportation when one (safe-ish) method is already

Good question. I learned it the hard way long ago. But it was still the 3D space in mind, although not with computers, but hand drawn pictures. I saw my neighboring programs with supposedly simpler linear algebra courses struggle with gauss

If I were to teach linear algebra I would stick to the 3D graphics approach. Maybe as far as including labs for implementing a ray-tracer. It is just the most fun, intuitive and eye opening application of basic linear algebra. Don't fo

Also remember that you (GP) already acquired that intuition in your youth. Most things you learn look trivial in retrospect. It may be that you already had some use of that. And if you had not learned those things you may have started worry

Yes! Most likely. And I probably described it wrong before. It was probably more the roundabouts combined with traffic lights that caused the mess. I remember thinking that someone needs to drop a bomb on this place or we'll be stuck f
