<p>Last year (2025), I lost count of how many times I tried using an LLM to set up Docker. It was still the era of prompting, then copy-pasting the response and seeing if it worked... and it almost never did. It’s great to see this new Docker agent. For me, it would be even more appealing to see an agent and a model specialized in Docker working together, capable of proposing advanced configurations and getting them working on the first try.</p>

<p>The promise of the so-called ‘malleable computer’:<p>a machine whose hardware parts you could change, as well as bigger chunks of its software, above and beyond end-user apps. That is possible via the integration of the OS with AI agents that do the heavy lifting for you in adapting the OS to your ‘needs.’ Users of the Pi coding agent get a better feeling for this because the tool is, by design, built to respond and adapt to user-commanded changes. This is the kind of capability the typical user won’t see in private-source OSes like Windows and iOS, especially because they have security as a concern (thus the OP’s motivation for the heads-up on security in Omarchy).</p>

<p>It's interesting to see in the post that the reading experience in the web page highly contrasts with the one in the eReader.<p>The website shows 15 words in the first line (10 in mobile). The eReader shows 6 words in the first line. In my own experience, I found that 6 word per line is the optimal number for comfort. (age thing? maybe)</p>

<p>Judo and Aikido founders were pals in the military. Those schools were all connected at the time and were complementary. What we see today is a kind of a "commercial struggle" between different schools and martial arts for $tudents. I practiced judo and BJJ as well throughout my life, and that wasn't an issue. I see that the ideal practice for anyone could be an MMA having the self-defense and the non-competitive healthy side of things. We don't see that mindset around.</p>

<p>Judo and Aikido founders were pals in the military. There is a handful of koshi nague throwing techniques that are identical in both schools, and are done without any of uke's momentum.</p>

<p>OP here. Lots of comments from non-aikidokas. Interesting and unexpected to me.  
The thing about "throwing himself" is pure self preservation that advanced students acquire with time. It looks nice on public demos, but you can practice the same techniques slowly in a way that the partner feels grounded, unable to create momentum. In those cases, the partner will feel a lot of pressure on their limb/join or back. Do that to beginner students and you'll see their eyes pop-out in desperation because the pressure is too great and don't even know they can tap to ease down.  
In advanced practice, if you don't do self-preservation, you'd end up with snapped tendons, broken collarbones, toes etc. If you are already injured, you have to tell your partner in advance "I can't roll today. Don't project me." or "Don't apply the elbow lock", and so on. So you won't see great projections either.  
Those are the details you can't imagine just by watching videos; you've got to be in the mat. It's like me watching fishing videos. To me, fishing can't be anything more than: throwing bait => pulling line.</p>

<p>I'm also from Brazil and share the same fears. I built a family note taking app which has an internal contact form for the same purpose. One can use it to contact family members in situations of having the phone lost/robbed. Now I'm looking forward to implementing an ephemeral web conference room via API so we could have emergency voice chat. I tried with Jitsi, but it didn't work for me.</p>

<p>I'm not sure if this an urban legend but, it's cool anyway. The name "Ramones" is an adaptation from "Jamon", Paul Jamon, a fake name Paul Mccartney used in hotel check-ins to avoid stalking fans. So most if not all Ramones members through history changed their last name, family name, to "Ramone" to honor the tradition and be a Remone forever in Rock history. Again, this is cool enough for me on top of the great music they've made.</p>
