I just found this video on YouTube now:

davidkwast··on So you want to use plants to reduce CO₂
Rainfall

And at least the forest soil has the same amount of carbon stored.

davidkwast··on AI Is a Bad Tool
I usually like to write elegant code using Python and frameworks like Django.

The pleasure comes from the "the only right lines of code" instead of "the most lines of code".

davidkwast··on Lossless GIF recompression via exhaustive search
Nice advice

davidkwast··on EAS Alarm at midnight caused by a hacker in Brazil
Everyone in Brazil capital cities are receiving extreme alert messages with just the text: "misanthropi"
davidkwast··on RFC 10008: The new HTTP Query Method
I would use a hash of the body content (the query) as a URL parameter

/?hash=123456789

davidkwast··on Thermodynamics rules future orbital data centers
So the majority of the hardware should stay on the moon where latency isn't so critical. There the cooling won't be the problem.
davidkwast··on Branchless Quicksort faster than std:sort and pdqsort with C and C++ API
It is so simple that I had to look very slowly to understand. Nicely done.
davidkwast··on Trump signs downsized AI order after weeks of reversals
As what we say here in Brazil:

"The world doesn't go round. It flips over!"

davidkwast··on Should you normalize RGB values by 255 or 256?
Your comment remembered me of ESA normalization value for the Sentinel-2 level-2 satellite image quantization.

Something like this:

Digital Number DN=0 remains the “NO_DATA” value

For a given DN in [1; 1;215-1], the L2A SR reflectance value will be:

L2A_SRi = (L2A_DNi + BOA_ADD_OFFSETi) / QUANTIFICATION_VALUE

davidkwast··on Reverting the incremental GC in Python 3.14 and 3.15
All Python versions are LTS if you consider 5-year a good measure.

davidkwast··on Reverting the incremental GC in Python 3.14 and 3.15
It is the same for me. Predicability is better than any optimization.
davidkwast··on Reverting the incremental GC in Python 3.14 and 3.15
"Python 3.14 shipped with a new incremental garbage collector. However, we’ve had a number of reports of significant memory pressure in production environments.

We’ve decided to revert it in both 3.14 and 3.15, and go back to the generational GC from 3.13."

Sounds the right move for me

davidkwast··on An Introduction to Meshtastic
You can use both. In the mountains I would appreciate redundancy.

I saw that in the code on the github repo
davidkwast··on Vouch
I think LLMs are accelerating us toward a Dune-like universe, where humans come before AI.
davidkwast··on Sqldef: Idempotent schema management tool for MySQL, PostgreSQL, SQLite
Wow. I saved the link for emergencies. And I sent it to all my team. It is like a diff tool but to advance the schema.
davidkwast··on AliSQL: Alibaba's open-source MySQL with vector and DuckDB engines
I don't think MariaDB ColumnStore has any kind of advantage. It is just an append-only storage format with some columnar concepts.

davidkwast··on AliSQL: Alibaba's open-source MySQL with vector and DuckDB engines
This ColumnStore is very simple and just do table scans sequentially on every query. It doesn't support indexes and unique constraints. It is almost an append-only serialization file format, but with some columnar concepts.
davidkwast··on MapLibre Tile: a modern and efficient vector tile format
I am hosting user data from the database. It is very easy with this stack: - PostgreSQL with PostGIS - Django with MVT-tiles plugin - MapLibre
davidkwast··on MapLibre Tile: a modern and efficient vector tile format
I do. The pros are hosting own data and have total control over stack and cloud hosting. The cons are having to code your own stack and do cloud management. I use PostGis to storage and serve vector tiles. And I use a simple backend with AWS S3 to store and serve raster data (GeoTiff COG).
davidkwast··on PCs refuse to shut down after Microsoft patch
It was nice in 2015-2017 when I got a free Windows 10 license for my Dell Ubuntu Linux Notebook (much cheaper to buy in Brazil). Back then most of the games only was on Windows. Nowadays I have a Lenovo with Windows 10/11 license but I do not used Windows since 2024.
