WOW! Gotta go visit Ireland some day. I am impressed!

Wow! Whatever you’re doing, lemme know. If it’s open source, even better. I’d love to contribute. AI for the good of society is smt I def wanna be involved with.

Hey. If you need to tell your model to ask permissions before doing anything you already lost. This is a concern for your coding agent, not smt the AI model can/should be able to decide about. It’d be wise to adjust the coding agent trust level of the project to have this security layer.

Hey Frazer, you getting involved in anything AI development?

Met him once at Garoa Hacker. Wonderful person! I told the story of how I met him countless times 😄

Same here. Mamdani seems to be a solution to a lost, adrift US

1951 IBM ad, selling a machine that “works for 150 engineers” 😂 Any similarity with today’s AI companies is mere coincidence.

I don’t really believe AI will be capable of this. It would, if big techs didn’t hold SO MUCH POWER in their grasp, so strong they could raise wars over control, natural resources, etc. In fact, I believe we’ll see global wars over power and control pretty soon, way beyond scales we got today.

Then, I did set up Linuxbrew over it. For the rare cases I don't find smt in CachyOS' repos, Linuxbrew will be there. I gotta say: the DX has been VERY good! I am finally satisfied with a desktop Linux experience. Who would think 2026 would be The Year of Linux Desktop? Well, it is for me.

000

Back in AcerOS (aka: a rebranded Ubuntu), I had moments of total fury when dealing with APT shenanigans to keep system up to date. In CachyOS, it has multiple pkg repos – one CachyOS-specific, with these CPU-optimized pkgs, and normal "Arch Linux" pkgs repos. There's everything in there! 🤩

100

Oh – I also been spinning containers and VMs with Podman Compose, and so far the Acer laptop didn't sweat on any of this. I gotta give kudos to Brave browser here, it's really impressive and performant, but overall CachyOS is indeed fckn performant. AND, this Arch Linux ecosystem is quite decent. 👌

100

I also do type VERY FAST, use lots of kb shortcuts, open links/etc. on new tabs like I had 1TB RAM, keep multiple VS Code windows on multiple Git worktrees open – and the laptop keep up with it all. I am not an ordinary desktop user and I know I demand a lot from the hardware/OS. I am impressed.

100

I finally installed this on my Acer laptop (I initially had it installed on a refurbished laptop I still have), and I been using this for a couple of months. Heavy use! Multiple windows of Brave browser with 20-30 tabs each (ADHD, you know), Slack, Telegram, WhatsApp (ZapZap app) + LOTS of agents!

100

It HAS the feature I was looking for! It comes with a setup of snapper over the btrfs. Perfect! Absolute cinema! So I got: raw performance (pkgs optimized for my CPU), a first-class btrfs support I can leverage, automatic snapshots whenever I touch system packages... It's a HUGE WIN!

100

I didn't like the name (still don't), but then it had this appealing thing of "performance-first", with pkgs optimized for specific CPU architectures. 🤔 Worth a try. I have other, way less powerful laptops, so I was testing CachyOS to see if it worked for them. It did. But then, I discovered smt,

100

So, I came in pursuit of smt new. Initially, I was looking for some transactional OS – there are some projects with interesting ideas over OS recoverability I'd like to adopt. Fedora Silverblue and OpenSUSE Tumbleweed were ones I was really looking at. But then, I found this CachyOS thing. Weird.

100

GOSH! It's so terrible. NOTHING you want is really there to use. The pkgs available are often super-outdated, "in the name of stability" or smt, and you end up struggling with installing additional pkg managers over the OS one to have things working. (I really like and recommend Linuxbrew, btw.)

100

It's capable of running some small models (4B ones with 50+ tps, 8B+ ones super-slow, but still running), and for 1K-ish USD in Brazil I thought it's quite a deal. But the UX of this AcerOS was *absolutely fckn terrible!* IMHO, the APT pkg manager from Debian/Ubuntu ecosystems is just NOT-usable.

100

It's an Acer laptop. CPU is an 8-cores/16-hyperthreads AMD Ryzen™ 7 7735HS, 16GB RAM DDR5 (expandable to 32GB), a 6GB VRAM RTX4050, and a decent 512 GB SSD NVMe PCIe 4.0. Came with an Ubuntu 25.04-based AcerOS which is pure trash! I hated so much I almost sold the laptop to buy another MacBook Pro.

100

I'm back to desktop Linux after 10+ years using Apple OSes. macOS is aweome indeed – the MacBook-iPhone integration is unmatched by anything else. But, my experience with a powerful 1K-ish USD laptop running CachyOS has been absolutely amazing! I am *very impressed* with CachyOS / Arch ecosystem.

(I too discovered this recently. Been trying to educate myself a bit more on Chinese culture since then.)

100

{:ok, "Joel Jucá"} @joeljuca.com · 04/09/2026

s/mandarin/chinese/ FYI, using “Chinese” is the adequate way to refer to the language spoken in China. “Mandarin” used to be a political rank, whose people spoke Chinese properly, “by the book”, while the streets used dialects (non-educated). The “language of mandarins” became Mandarin.

TIL I can `git diff -U9999` to visualize editing files in full, instead of seeing only the specific parts where it has changed. Useful to see changes along the whole file to really understand how your changes are affecting the file itself. I needed this just now to reason on my changes to my .zshrc

It works great! And, once you get the hand of BW Secrets Manager, you’d have BW secrets in your CLI as well

He’s beautiful. What’s his name?

You can just `dd` an iso/img file downloaded from microsoft.com onto your USB stick. Trust on HTTPS and checksums, they work.

I guess you’d like to hear the new initiative from the Open Source: bootstrapable software. In a nutshell: a build system that pulls everything from source — compilers, tools, etc., everything to compile and build software from bare scratch. Controvertial ideas. Interesting tooling.

When I have these moments and some random Joe says “just do it with AI” 😡 all I think of is how much brainrot this person is suffering. The AI companies made such incredible marketing around their products that people believed it’s all magic.

2:14 am and I was on my laptop, tackling the challenge of performing automated core reviews with AI: the pi agent running on a GitLab CI job with everything it needs to clone the repo, check the GitLab diff, then run a code review that includes, if it decides: web search, tool calling, etc. +

110

Lots of people leaving 1Password for Bitwarden after 1P became supporter of DHH/Omarchy. Just wanted to say WELCOME TO THE CLUB, FELLAS! If yall have questions for someone using BW for quite a while (cloud version, no self-hosted; yet), send them it. Bitwarden rocks!

000

Oh, come on! You’re too early in the process of hating big techs 😂 You gotta spend some time researching alternatives. Every single big tech has alternatives, open source of not, etc — you gotta find them to be able to hate big techs properly. Eg: I been using HelloChinese. Works for Chinese. 😄

120

What are the alternatives? Have you gone through the hassle of researching this?

Pretty cool! Is there a website, GitHub repository, etc I could follow, see it growing?

The biometric thing is appealing! I’ll give it a try

What I like the gpg approach the most is the UNIXy way of doing it. I came up with this idea ~2 months ago, tested some approaches and got a damn good [and secure] one to work with. Today I don’t see myself not doing this! The DX is really good.

direnv – unclutter your .profile

direnv (direnv.net) does the magic of loading secrets in shell whenever I cd into my project dir to run some cmd that requires a secret. So, I can eg: spin my pi agent and have some API keys loaded right in time. And there’s Bitwarden Secrets Manager (the bws CLI) for the most sensitive API keys. 👌
