I've been using Pulumi for >1 mo, and have spent the weekend doing a small project with it. So far I can't shake the feeling that I shouldn't have so much power while defining company-critical infra.
Give me my TF, where even the most inoffensive local-exec will rise eyebrows.

I almost became the first victim of “LLM word choice-induced cardiac arrest” today.

This post makes me feel like it’s 2015 and I love it.

This applies to life in general, now that I think about it.

The game is more fun if you commit to the bit. But also: sometimes the “wrong” option turns out to be the best choice.

Copilot adds “nitpick” comments on PR reviews, therefore confirming my hunch that we have reached AGI (it is now indistinguishable from an unengaged engineer with bad communication skills).

I agree with Mehdi that I think we’re moving into a world that incentivizes smaller orgs and teams. You can do so much with very few engineers today

I don’t think I buy the argument that mid-sized companies are dying though. You’ll still need to scale up eventually, just later

Or very strong magnets!

The world is going through some shitty stuff, but it’s so weird to see US people post about it on here all the time.
As far as I can see, everyone who sees your posts agrees with them, so what’s the point?

I was reading and annotating the Viewstamped Replication Revisited paper, and all of a sudden, Preview (on Mac) seems to have flushed all my notes down the toilet.
What are some good apps to read papers on? #pwl #ismacosthenewwindows #distsys

It’s hard to make a pretty diagram of a complex system.

People focus a lot on the law of diminishing returns, and not enough in the law of noob gains: when you have nothing (incl. knowledge), gaining anything is a ∞% delta.

Way higher

Gut feeling: if you have a big enough distributed system, and you aren’t using Kafka, you’re reinventing it.

Going through my private repos and apparently I tried to write a book about DevOps 9 yrs ago.
Yikes.

If you can estimate accurately how long it would take you to make something, leave it to an LLM and find something valuable to focus on instead.

The thing about software eng is that, unlike some other professions, many people get into this for fun. It's all about play and curiosity.
