Rust intern saved TikTok $300K
A TikTok intern rewrote CPU-intensive payment service endpoints from Go to Rust, reducing average latency by 30%, P99 latency by 76%, and cutting compute costs by 50%โsaving $300K annually. The migration used a gradual rollout strategy with separate Rust clusters under the same service name, avoiding upstream code changes. Key challenges included adapting Go's zero values to Rust's Option enum and optimizing memory allocations. The main lesson: Rust delivers performance gains at the cost of developer productivity, making it ideal for high-usage, stable components where economies of scale justify the rewrite effort.

I recently discovered tmux, and honestly itโs a super useful and really cool tool.
It lets you manage multiple terminal sessions inside one window, keep processes running in the background, and come back exactly where you left off.
Once you get used to it, itโs hard to imagine working in the terminal without it.
Tmux = terminal + server

Grapheme cluster
A grapheme cluster is one character that humans see, even if the computer stores it as many parts.
ASCII
Old system
1 character = 1 byte
A B C 1
No confusion.
Unicode (modern text)
รฉ = e + สผ
Looks like one character
Stored as multiple parts
That one visible character = grapheme cluster
JavaScript
JS counts UTF-16 units, not what you see.
Rust
Rust counts UTF-8 bytes.
Final idea
Computers count bytes.
Humans count grapheme clusters.
