- Deno plugin in editor, otherwise types dont work

- All imports via absolute URL, like Golang

- No backwards compatibility, so no existing code worked.

Since Deno 2, they've taken Node compatibility much more seriously, hence the 50% to 70% compatibility jump claimed here.

Bun on the other hand, tried to make things Just Work without requiring any thinking for Nodejs / TypeScript developers. It's basically the `node` development experience with all incidental frictions removed (but some segfaults added).

tl;dr: you can use `bun` to write node projects, but `deno` can only be used for deno projects

SQLite uses a LALR(1) parser generator call Lemon (similar to Yacc). I patched Lemon to dump its parse tables to JSON, then ported SQLite's [parse.y][] grammar to TypeScript with some help from Claude. The result is this library, which I think is the fastest JavaScript SQL parser out there:

      ~2.5x faster than liteparser (wasm)
      ~6x   faster than @guanmingchiu/sqlparser-ts (wasm)
     ~10x   faster than node-sql-parser
    ~100x   faster than pgsql-ast-parser
    ~200x   faster than sqlite-parser
    ~250x   faster than @appland/sql-parser

Launch 1 True Recovery, open Terminal, then run “bputil -a” (without the quotes) to downgrade system security and allow for more boot arguments. You might need to restart after this step.

Then, run [nvram boot-args=”-s”] (without the square brackets). Restart to launch Single User Mode.

Once in Single User Mode, run these commands (in the following order) to mount the root volume group:

1. mount -P 1

2. /usr/libexec/init_data_protection

3. mount -P 2

Future restarts will always launch Single User Mode first. To stop launching Single User Mode, run [nvram boot-args=“”] (without the square brackets).

To restore your system to full security, run “bputil -f” (without the quotes). If you choose to run that command in macOS, prefix “sudo” to the beginning.

pujil's patch alebgra is sick but the whole system implementation is so complex my guy is still toiling away on it, unfinished, after half a decade

Personally I think not enough credit to macOS here; Apple's Mach/XNU has been microkernel flavored since the NeXT days and many subsystems run in userspace like Windows.

And its not like Github's load stayed linear over the last 8 years since the acquisition. Repo creation and pushes went exponential about 2 years ago with the AI boom, so even with fantastic execution I think they'd still be struggling hosting the ever expanding archive of all code in the world.

I’m pretty much using 90% Codex now, although since Claude is consistently faster at answering quick questions, I still keep it open for that and for code-reviewing codex/human work before commit.

i’m happy to change the oil on the 2026 one for a few more years

orchestration

docker / virtualization framework is for one machine

this stuff is for 100s - 1000s machines

If the S3 Files sync logic ran client-side, we could almost entirely avoid file access latency for cached files and paying for new expensive EFS disks. I already pay for a lot of NVMe disks, let me just use those!
