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

> I can’t say I’ve installed a huge number of snaps but when I have they worked

Thanks. Any apps you avoided installing as snaps?

Ask HN: Is snapd still controvertial on Ubuntu?

mariocesar — Mon, 15 Dec 2025 12:42:29 +0000

I've been on Debian and sometimes Arch for years and wanted to try Ubuntu Desktop again. What surprised me is how often Snap shows up as the "Recommended" install way in their docs and others software "Install in Ubuntu" is mostly with Snap.

If you're using Ubuntu for Desktop today: how is Snap in practice? Any real pain points or is it basically fine now?

It's worthy?

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

However, I really enjoy it!

mariocesar — Wed, 10 Sep 2025 12:50:40 +0000

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

New comment by mariocesar in "Malleable Software"

mariocesar — Wed, 27 Aug 2025 14:11:56 +0000

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.

mariocesar — Sun, 10 Aug 2025 21:19:01 +0000

If the goal is to learn about computer science, then yes absolutely. However, if the goal is to better one's chances of securing a meaningful and well-paid job, the answer is no.

If you're curious, the code in ellipsis results in executing:
