En el newsletter de Rails mencionaron este PR: https://t.co/6TNqEWvbRu

Le pedí a Claude que mire si algo de ahí nos servía.

Cierre:
Así como tratás las dependencias como código propio,
tratá también los sistemas externos igual.

Porque cuando algo se rompe,
igual sos vos el responsable.

Ayer di una lightning talk en la meetup de RubySur (https://t.co/RRiUa5g7wR).
Historia corta: terminamos debugueando un bug de altas duplicadas que cruzaba 3 sistemas: billetera, nuestra app y autopistas.
Nadie encontraba el problema.

Takeaway:
No alcanza con entender:

- tu código
- tus gems

También tenés que entender:

- proxies
- CDNs
- protocolos

Doing my best to keep the codebase (and complexity) neutral.

TIL wrapping a command in () runs it in a subshell (a child process).

$ x=1
$ (echo $x)
1
$ (y="hola")
$ echo $y

Learned this while running many:
(dotenv -f .env.<destination> -- kamal deploy -d <destination>)
so env vars don’t leak into my shell.

One huge benefit of coding agents:
you can delegate this kind of obnoxious but necessary work and move on with your life.

Pretty sure a client audited an app I maintain last night.
Saw some null byte injection attempts in Sentry.
I am pretty sure modern Ruby (& Rails) is basically immune. Still added some sanitizing middleware.
The fix is already in prod.
Still waiting for the audit report.

Same client once “invited” me to upgrade Bootstrap because of a vulnerability in the carousel.
Yes, the carousel.

I got so used to CLI coding agents that IDEs like Cursor or VSCode felt like an overkill. Too slow to just check something or change a comma.

I googled “neovim for normies”. We’ll see how it goes.

I would like to have a agent (or skill or whatever) that analyzes git logs and tells me how many dependencies I added and how many I removed.
That net negative number is all I need to know how good the year was.

Hoy fui a la oficina con el mismo short que uso de pijama.
Otra acepción de home office.
