Pentagon Refuses to Say If AI Was Used to Select Elementary School as Bombing Target

Did the US military use Anthropic's Claude to select targets in its weekend operations in Iran, with devastating results?

TIL: should I use single or double quotes in git commit messages?

both works fine, but go for the single quotes; double quotes might trigger "command substitution" on unix-like systems

for example:

```bash
$ echo "`ls`"

./docs/
./node_modules/
./package-lock.json
./package.json
./pages/
./README.md
```

I've been reading one text per day from "felicidade clandestina" book by Clarice Lispector. because the texts are short, it's easy to fit into my day and I've been loving it!

it's been fun @marcoroth

I've been playing around with the `gum` gem from the `charm-ruby` ecosystem to glam up my scripts and aliases. I wrote a script that makes your scripts available from anywhere on your system.

what are the exciting features in ruby 4 release?

experimental `Ruby::Box` isolation mechanism; new zjit compiler; performance improvements for class instantiation; `Set` and `Path` classes promoted to core classes

TIL: what's git commit amend? does it modify the previous commit?

it's like a time travel; rewrites the repo timeline; amend staged files to "previous" commit; previous commit is actually replaced and not modified; commits are immutable

#git #softwareengineer #learninginpublic #devlife

I wrote more about the libraries, how to get started, and what's next on my blog, including a lot more demos:
