What functional programmers get wrong about systems
Type systems verify properties of programs. Production correctness is a property of systems. The gap between these is where the interesting failures live.

Nobody knows how the whole system works
One of the surprising (at least to me) consequences of the fall of Twitter is the rise of LinkedIn as a social media site. I saw some interesting posts I wanted to call attention to: First, Simon W…

Running Your Own AS: BGP on FreeBSD with FRR, GRE Tunnels, and Policy Routing
How I obtained my own AS number and IPv6 prefix, set up a FreeBSD BGP router with FRR, and built a tunnel overlay to bring globally routable addresses to servers that already have provider-assigned...

Things Unix can do atomically (2010)
This is a catalog of things UNIX-like/POSIX-compliant operating systems can do atomically, making them useful as building blocks for thread-safe and multi-process-safe programs without mutexes or read/write locks. The list is by no means exhaustive and I expect it to be updated frequently for the foreseeable future.

A few CPU hardware bugs
Catherine (Whitequark)’s recent observations on poorly-engineered firmware reminded me of a few mistakes I’ve seen in vendors’ CPUs; some unimportant and others surprisingly bad. Since I’ve never seen these widely discussed, here’s some discussion and links to supporting evidence to make them more widely known, since…

How to Scale a System from 0 to 10M+ Users
Scaling is a complex topic, but after working at big tech on services handling millions of requests and scaling my own startup (AlgoMaster.io) from scratch, I’ve realized that most systems evolve through a surprisingly similar set of stages as they grow.

Is the RAM shortage killing small VPS hosts?
The AI surge has DRAM producers like Micron focus on HBM (High Bandwidth Memory) to serve AI hyperscalers over the DRAM (Dynamic Random Access Memory) used by ordinary consumers and small businesses. Consequently, for instance, servers which used to cost $2500 on Newegg now cost $5000. RAM alone is $2500 now.
