Linker, can you spare a meg? (2021)
Tailscale on iOS runs as a special kind of app, a Network Extension. This lets us run in the background, so we can secure traffic from all of your applications, without them having to change anything. But with this power comes a memory straightjacket. Normal iOS apps can use 5GB or so of memory before iOS kills them…

Memory safety for the world’s largest software project
Rust for Linux and Prossimo The Rust for Linux project aims to bring a new system programming language into the Linux kernel. Rust has a key property that makes it very interesting to consider as the second language in the kernel: it guarantees no undefined behavior takes place (as long as unsafe code is sound)…

Speeding up Go's built-in JSON encoder for large arrays of objects
I was looking into some of octosql 's benchmarks the other day and noticed a large chunk of time in DataStation / dsq is spent in encoding JSON objects. JSON is an intermediate format in DataStation and it's pretty inefficient. But the reason it's used is because almost every scripting language supported by…

The world of PostgreSQL wire compatibility
A wire protocol is the format for interactions between a database server and its clients. It encompasses authentication, sending queries, receiving responses, and so on. It is a description of the exact bytes sent and received by servers and clients. It does NOT encompass the actual query language itself, let alone…
