No point, I just shared something I did

`claude --resume` will list your sessions, you can copy the title. Codex may just list and grep the sessions files in ~/.claude and filter the one with the name.

I also have the habit of naming my sessions with `/rename`

I'm was closing a day of work and it stopped in the middle of a long plan, I started codex and tell it: "I was in the middle of work with Claude could you read the plan and the session "x" in ~/.claude and continue the work" it just completed everything :D

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!

Cool, if we could by hour I can replace my CBT tracker !

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

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

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.

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.

Just start using it! It really makes sense the % progress.

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

There is a Japanese show that made a Scientist vs Engineers version to build the best Spinning Top: https://www.youtube.com/watch?v=-q-hcidtjiM

Awesome!

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

Thanks. Any apps you avoided installing as snaps?

I open a few pages and then press Command+W, that close the tab :/ muscle memory.

However, I really enjoy it!

Nice! I build something similar but without the checks and selection. my dotfiles include an idempotent install script and a Brewfile with all my packages. The selection and checks features you've added, that's a great touch!

Something I'm not able to do nicely is to sync browser profiles, I end up doing all the setup and login step by step, it takes me an hour or so

Yes it does

I've been in SaaS for about 17 years, and a pattern I've seen is that for companies customers actually love, customization shows up as a milestone. It helps them find their own way of doing things, but eventually they settle into that way.

When it resonates with customers, it feels great.

Customizable SaaS is really just a side effect of the deeper need for control, because with control you can execute better. And when that lines up with capital, market fit, and a clear purpose, it creates more than efficiency, it creates meaning.

The companies that never settle, always chasing new patterns, usually end up with customers who don't enjoy them and employees who don't enjoy the software either.
