Decided to fire up Claude Code with Opus 4.5 and try to re-implement a toy language in Crystal targeting WASM 3.0, gave it a few sources of inspiration and comes with really interesting feedback.

Been there, done that, OSS burnout: opensourcepledge.com/blog/burnout...
I still recall getting emails yelling at me about their "lost profit" due a bug on my *check notes* free code.
Or getting mocked by others supposed _fellow_ open-source devs, who knows why.

If we are having a conversation and during it you say to me "let me ask [insert your AI chat agent name here]" I will immediately consider the conversation over. You cannot outsource your thinking to a blob of floating point numbers (it is ok not to know the answer).

There's been endless talk about an AI bubble, but less about exactly how, why, and how much it's a bubble. So I turned to the framework put forward by scholars Brent Goldfarb and David A. Kirsch, authors of "Bubbles and Crashes," for assessing tech bubbles.
Spoiler: On a scale of 1 to 8, AI is an 8
Spoiler: On a scale of 1 to 8, AI is an 8
AI Is the Bubble to Burst Them All
I talked to the scholars who literally wrote the book on tech bubbles—and applied their test.

When AI wants to test everything under the sun, you can just make it go back to the basic by asking "check how we are doing it right now"... KISS, baby. 😉

Dear fellow open-source devs: its OK to use an AI to help you out (heck, I use it too!) and I would understand you don't have the time to review every reported issue, but I would rather prefer radio silence than an automated "AI analysis" to the issue I just reported. 😔

One day the industry will recognize the drawbacks of AI agents and nondeterministic automation, and rediscover the UNIX philosophy of chaining together small purpose built tools in a low cost and predictable way, otherwise known as shell scripts.

I've been blown away by Uncloud and unregistry from @psviderski.bsky.social, to the point that I'm actually enjoying deploy again!
Build and deploy under seconds. No need for external container registry, all streamlined.
Previous deploy metrics: k8s: 5min!. Swarm: 30s, Uncloud: < 5s. 👏🚀

I love that Forgejo (a fork of Gitea) is run under Codeberg's, a non-profit organization. The funny thing: they have a custom version that they deploy to run codeberg.org itself: codeberg.org/Codeberg-Inf...
![Forgejo (Codeberg)
Codeberg's fork of Forgejo, a self-hosted lightweight software forge.
Some changes made to Forgejo's source code are:
« Codeberg-specific themes
« Codeberg's custom landing page
« Codeberg's custom footer
« Various optimizations necessary for running a large instance
« Dirty hacks that we needed to deploy as soon as possible
Some of our patches may be helpful if you wish to operate a large Forgejo instance. However, this repository as a
whole contains a custom version of Forgejo that is explicitly not intended for private use.
[Codeberg and Forgejo work together, but, as projects, they remain separate. For more information about Forgejo
land its relationship with Codeberg, take a look at Forgejo's FAQ]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ke42z4esrgumoobfvxxtmnhf/bafkreibod5eklf6qndhjr5veponefzjbgmf6mxpgdvpa5xs5umz7tctje4@jpeg)

My mom used to say "even a broken clock is right twice a day" (in spanish). It is important to check it at other times, as sometimes people are right "twice a day", not because they are smart, but just by accident.
