I recently wrote an explainer for the sqlite file format with some helpful diagrams. This might help. https://blog.jabid.in/2024/11/24/sqlite.html

Immutable append only persistent log doesn't imply store everything _forever_. If you want to remove something you could add a tombstone record (like Cassandra) and eventually remo…

A notable example of a large-scale app built with a very similar architecture is ATproto/Bluesky[1]. "ATProto for Distributed Systems Engineers" describes how updates from the user…

Pkl was one of the best internal tools at Apple, and it’s so good to see it finally getting open sourced. My team migrated several kloc k8s configuration to pkl with great success.…

This is what I wanted Apple News to be. I wish it would give me a good curated news feed from dozens of sources, and adapt based on feedback. I badly wanted to love it, but no matt…

RAFT is not BFT. You need nodes to cooperate. If the nodes lie, the system will collapse.

I did exactly the same last night and you don't need the echo $? hack anymore.

You read my mind :D

Just tinkering with the tools and writing some code helped me a lot more than the university course I had 6 years ago. There are several beginner friendly online resources now incl…

You are right, the compiler cannot handle much of higher order functions and closures yet. I have hinted how to do that with lambda lifting and closure conversion and I might get i…

You are right and calling it quintessential might be too much. Local lexing seems interesting, but the approach I used is called combinatorial parsing and it does parsing and lexin…

Author of the post here. AMA :)

Unless you have lived in the tropical humid heat, you wont be able to relate to this. Moving to NYC recently and living without an AC or even a fan feels so glorious. I bet 10% of …
