slop update: while doing weekend activities, added PG/MySQL wire protocol (benchmarked 2M qps), Raft based clustering and lots of other things, built a beautiful website - slopdb.dev/

Code is cheap, so I built 'poortrace' - bpftrace-like tracing script that uses ptrace and perf events and doesn't need root/sudo - Rust, LLVM, resolves JS/Go/Py stacks, DWARF support, many output formats (flamegraphs, speedscope, json), dynamic uprobes, USDTs, profiling, ...

"make it faster" prompt unattended pushed SlopDB to 15M q/s on a test VM - SQLite has to be in immutable mode with isolated caches to reach 3M q/s, and is single-core bound when a cache is shared.
Obviously, reducing Go heap allocator usage was the key - github.com/midom/slopdb/comm…

Transactions (for DDL too), deadlock detector, optimistic and pessimistic modes, online alter, quite some introspection, unicode normalization, lots of SQL syntax, borrowing both from PG (RETURNING, ON CONFLICT) and MySQL (ON DUPLICATE KEY), etc.

Golang, LSM, scales well with concurrency, handles TPC-H like a champ.

Is nothing sacred to these AI freaks???? Mark Zuckerberg and Larry Ellison just built this monstrous data center in the very heart of Paris—only steps away from Notre-Dame and the Louvre. Can’t the EU do something?

Sometimes I just don’t understand what universe other people live in. One moment you’re looking at MM/FS contention, other second… it is a file! It scales!!!
Thank you. The people who claim SQLite doesn't scale absolutely have no idea what they're talking about and have 0 imagination. It's a freaking file, spin up as many SQLite files you need, at any location you want. Concurrent writes have been a solved problem for a long time.

The idea that all billionaires got their money by exploiting peopl doesn't hold up to any scrutiny.
JK Rowling wrote books about cheeky wizards. I invented a better way to make virtual reality headsets and games to play on them. We just made things people wanted.
Interesting to compare Project Hail Mary IMAX experiences at Hacienda Crossing vs TCL Chinese Theater. Big fan of that screen in Dublin, CA

Of course AI uses lots of sea water - you need to extract deuterium for fusion reactors, etc - the reason to colonize other planets that have oceans on them.

Interviewer: How do you…
