To ask for web search, simple commands and research, or passing logs to analyze it's more than enough

Here is the script https://github.com/mariocesar/dotfiles/blob/main/common/.loc...

I have an 'ask' alias in my shell that just uses Haiku. I use it daily for pretty much everything

For more long work, I now use Fable to create a PLAN.md. I tell it to make a plan that will be executed by other models, and most of the time it ends up choosing Opus or Sonnet.

I didn't start doing this recently. Before that, I would just use the top model for everything. Splitting the work across different models depending on the task has helped a lot. They run faster, and I usually get much better results

Great work, and thanks for sharing the transcript! Just skimming through the chats, I've already learned a lot. Would be so awesome to have this for any region/city, but that is a data problem to solve.

Congrats again!

This was posted on HN a while ago and I started using it then. I've accumulated quite a bit of data and have used both export and import. That's turned out to be the most useful feature for me

I've used other trackers, ones focused on CBT. My only suggestion is to allow text notes in each entry, so I can track emotional states or recurring thoughts

New comment by mariocesar in "Ask HN: Alternatives to GitHub"

mariocesar — Mon, 17 Aug 2026 14:24:05 +0000

I answered this in another thread, if you're already running a large GitHub organization, GitLab is the closest alternative in terms of features

A big plus is that it also has an open-source Community Edition that you can self-host

New comment by mariocesar in "Incident with Github.com"

mariocesar — Mon, 17 Aug 2026 14:13:39 +0000

GitLab is probably the most reasonable alternative. I migrated and it took me some weeks to adapt to the new CI, but for my use case it's basically equivalent in features.

I started with the cloud version, then moved to self-hosted because it wasn't a big effort for our team. We also reduced our monthly invoice by about 50% after the move.

The product is being launched before the value is clear.

We've seen similar waves with new technologies before: overexposing the pros, dismissing the cons, hyper-optimism, and people using a lot of jargon without saying much of substance. The difference this time is the scale of the impact and the volume around it.

New comment by mariocesar in "Ask HN: How long have you been looking for a job?"

mariocesar — Mon, 15 Jun 2026 23:51:16 +0000

I've been looking for almost two years, though not very actively at first. I had to focus on my health, and job hunting took more energy than I had

Two months ago, a local company reached out on LinkedIn. They help with the search. I'm not good at selling myself, so I gave it a shot.

They fixed my CV and LinkedIn, and started finding roles for me. Since then, I've had more interviews.

The market feels over-automated now. Too much noise, too many filters, too much AI. It's exhausting.

Agree with Gitlab as an enterprise alternative. Beautifully boring and safe to have complex teams and permissions. Also has a good enough Terraform support, and a nice workflow to host docker images

I made something similar years ago, a long one-liner.

  tar cpf - provision/ | ssh ubuntu@192.168.1.99 "tar xpf - -C /tmp && cd /tmp/provision && bash /tmp/provision/bootstrap.sh && rm -rf /tmp/provision"

Heres is the full use: https://gist.github.com/mariocesar/8e674ec40dad6b94114d2a44d...

I named "Ansible for the Frugal"

Feels like Ansible does the same thing, just with nicer output

Same surprise here. However in practice, the community tends to talk about DuckDB more like a client-side tool than a traditional database
