Twitter used to be cool, offering news about Rust and Python. Now, X feels like a cheap copy of TikTok.

I love reading such detailed technical articles, those guys took Kafka apart and managed to understand the cause of their 3 seconds write latency in Kafka producers. Turns out it was caused by the flush/commit of the ext4 file system journal metadata. Of course doesn't mean ext4 is bad it's just not a fit for Kafka's workload. So they end up switching to XFS and improve the writes by 82%!

The way they discovered this is interesting, all the tooling they wrote for Java/Kernel is just amazing, recommend you guys checking it out.

I'll make a video covering this in details once I get a chance, I want to learn more about XFS and ext4, my knowledge there is limited.

I did a brief summary on the article on my second channel for those interested https://t.co/CZFOsrNxL9

Así quedó el Saeta Café, detenido en el tiempo, luego de que el 10 de abril de 2001 se produjera una explosión en el sótano.
23 años después, la esquina de Perú y Chile revive con el mismo nombre y honrando su historia.

#Python tip: Start 2024 right by mastering the itertools module.

I recommend working through the itertool recipes one at a time until you understand how each of them work.

After an hour or two, you will be an itertool boss.
