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

On: GitHub is sinking

[mariocesar]

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

On: Scotty: A beautiful SSH task runner

[mariocesar]

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"

[wang_li → mariocesar]

Ansible only exists because of an influx of people who don't know how to do this.

[everforward → wang_li]

Ansible exists because it makes things idempotent, which is great when you have to do a thing on 1,000 servers because you can just fix the role and re-run it.

Bash can be idempotent but isn’t by default, so you either spend time making and idempotent bash script or you spend time learning Ansible to accomplish the same thing in a reusable way

[wang_li → everforward]

Ansible’s idempotency is dependent on the specific module being invoked. What ansible mainly brings to the table is the parameterized modules. Which brings us back to people adopting it because they don’t know how to compose one liners, quote them properly, and wrap them in a for loop.

[icedchai → wang_li]

Many years ago I wrote my own "cloud instance bootstrapper" that would pull a tar off of S3 based on EC2 instance tags / metadata, untar it, then run a script. I never got into Ansible and I hated having to rebuild AMIs for minor changes.

[mariocesar]

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

[verdverm → mariocesar]

Feels like Ansible has more in the pros column than just nicer output, imo

On: I overengineered a spinning top [video]

[mariocesar]

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!

[johndough → mariocesar]

The entire "Supreme Skills!" series is amazing. Highly recommend!

On: Databases in 2025: A Year in Review

[mariocesar]

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

On: Ask HN: Is snapd still controvertial on Ubuntu?

[mariocesar]

> 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?

[PaulHoule → mariocesar]

No, but my use of GUI apps on Linux is limited.
