Hi HN, showcasing my project over the last years (again). The updated LC-Product works now pretty streamlined and it makes pretty interesting (and surprisingly good to compress) maps. Stack is a collection of adjustable U-Nets that make pre

Interesting read - there's a lot of progress in the open map styling scene and OSM maps with good data can make amazing maps and it has many different features [0]. It's also interesting to make maps directly from raw data (in t

Interesting default rendering choice for `()` in their demo pretty printer. It renders a space before each opening parenthesis.

Isn't what you describe a PID-controller: https://en.wikipedia.org/wiki/Proportional%E2%80%93integral%... AFAIK that is the common approach to solve this problem, but it still needs some degree of sensor accurac

Interesting. Came to similar conclusions when analyzing my (httpd) access logs for https://turmfalke.httpd.app/demo.html ... but so far nothing really out of the ordinary.

Yes, I am aware of Sentinel-2 10m data (RGBN), there are even commercial offerings. Actually the storage requirements are not that big for 10m, like ~4TB for the entire (non-water) world. Napkin math: - 15000 Sentinel-2 scenes over la

It's a nice start but what we also need would be an "OpenRasterMap" project - a project where we collect raster data (more and more data gets available) and store the entire planet (RGBN aerial imagery) in let's say 1m&#

That's actually a nice idea. I guess we will see more software in the source code dependencies analysis space. There's so much code and often it's nice to have some kind of metrics (LOC, PageRank, ...) to get a grasp of what&

Wow never heard of GBIF, but you seem to offer useful data. Am I correct that you are in essence providing georeferenced animal/plant population data across the globe in mostly CC license? So, good luck!

That would have never worked because such a license would be at odds with free and open source licensing and Docker wouldn't have gotten any traction in these communities (that provide the infra backbone of the whole stack). I get your

"Working" can be interpreted differently. 75% accuracy (?) is not that great for predicting a specific class (depending on distribution on course). If you need high accuracy, let's say for e.g. estimating eco system performan

Probably because it is mostly compared to Python - which is arguably a low bar to beat.

Yeah and hosting it by yourself is slightly non-trivial as the storage requirements are in the PB range.

That's a good one, did not know that. Interesting read.

That's why we have this bloated over-engineered multi-node applications: People just underestimate how fast modern computing is. To serve ~2^6 requests/sec is trivial. It's easily served by a simple server.

You are technically correct. The best kind of correct. :)

Yes, I may have worded that wrong, it's certainly possible . But is it reasonable ? By that, I mean can it compete in performance with C/C++/Rust?

It's interesting to see that many long-standing members of the Haskell community take a look into (or even heavily use) Rust and add it to their repertoire. This is really a good sign for Rust (Haskell folks normally have high expectat

Note that "Umwelt" is just the german word for "Environment" (or "Surrounding") - which actually fits in this context.

That's true, but there is also cloud.hetzner.com. It is rather newish and lacking most features the big 3 offer, but it might be getting there.

It's true, I don't have any problem with using SPACE via left thumb, but I have never encountered a layout or keyboard that let's me use the thumb for modifier keys. Do you have an example?

Many years ago I too had pain in my wrists while doing lots of programming work. For me the game changer was using Vim and mapping ESC to jj in both the editor and the shell (via .inputrc). In fact I mostly use Vim because of the provided e

Very true. Part of the reason is probably that you need the proprietary drivers to use CUDA efficiently and as they are not in the (upstream) kernel you have to use some other tools, like unofficial repositories or the native installer (whi

For a long time, I thought awk was just an abbreviation for "awkward" (in fact it is named after its inventors, Alfred Aho, Peter Weinberger, and Brian Kernighan) which seemed fitting as its syntax looks arcane (compared to modern
