Last Notes npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…vq02 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Yesterday I met someone who doesn't know who "Microsoft" is... npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…vq02 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 So, if I can't trust an IoT device, a camera, a printer, any smart device that calls home, and now some brands of TV and set-top boxes, what is left to trust in my network? Should I just have one VLAN per device type and not let anyone talk to anyone? npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Another Pi bites the dust. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…vq02 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 New blog post! I 3D printed a 10-inch (10") rack for my homelab. It was a very long project, but very rewarding at the end. Since I had a lot of help from various people on Mastodon and other communities, I felt like it would be important to show what I did. Also I hope that while I'm sharing my thoughts and the process to get there, I would be able to help other people with their own projects. And if my project works as inspiration for yours, I would be very happy if you let me know about it! npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 I never worked as a professional developer, but my constant curiosity, and my line of work, always led me to do a lot of coding. So much so that at some point (a long long time ago) I boasted being able to write useful/functional applications in 12 different languages. I stopped counting, but I kept adding a lot more to the list. Obviously I forgot about most of the ones from the distant past. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Once again a 30 minute 3D print saved me $30 dollars, 7 days of waiting, and all the pollution caused by bringing something all the way from the other side of the world. I like this future. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 I have some parameters for some Linux commands which are burned in my brain, and work for 95% of my needs: npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…nr3z @nprofile…l9z3 @nprofile…h0ux npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…l9z3 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Rust is a great language, I agree. It does solve a lot of problems, sure. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…l9z3 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…lc5w npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…z52u npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…z52u npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 The idea of Matrix as a chat service is nice. But the fact that it keeps going out of sync, and I keep losing messages from other people is just plain annoying. This is worse than IRC net split (at least there was a message when it happened). npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 (To the anti-AI people: please feel free to ignore/skip this post.) npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…p9dw npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…p9dw npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 The best way to test the resilience of your service is: reboot the server. I mean it. Don't just restart the service, reboot the server. A story in two parts: npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 I have backups for my servers. I have a script that notifies me when the backup succeeds or fails. I manually run backups before any software upgrades. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Just wanted to give another shout out and thanks to @nprofile…lc5w and his amazing Spook Home Assistant integration. I just got a new phone, and Spook made it really easy to spot all the places where I had to make the necessary configuration changes. Thank you! npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 I just re-watched the original 1979 "Alien" movie, and now I understand some of the weird things that happen in the "Alien: Earth" TV show. I read in a few places that they both happen in the same universe, but they should not be treated as directly related. Well, nevertheless, for sure I will enjoy the TV series more, and most likely will watch the other movies of the franchise. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…cfw2 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…7v9l npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…7v9l npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…mcgw npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 I'm here having fun at the #HADay2025 in Charlotte/NC.

Both have the same exact problem: they report the illuminance and temperature *once*, when they are paired, then never again. The motion sensor works fine, but lux and temp not at all. I thought it was a device problem, but it happens with two devices, and I don't have a Philips Hue Bridge, so I can't update their firmware. Thoughts? npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…2sd7 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…2sd7 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…cfw2 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…3kq5 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…mcgw npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…xcsy @nprofile…z22s npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…mcgw @nprofile…2sd7 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Sometimes, when you break stuff, it's not worth fighting it. Simply recover the backup and move on. npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…74c4 @nprofile…7nr8 @nprofile…g8jv @nprofile…kgua @nprofile…xt5t npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…lqnp npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…dxvj npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 How in the world did I not know this existed? hahaha 🤣 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…d2rl npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…dxvj npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 @nprofile…p5pe @nprofile…2sd7 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Every time I run "dnf upgrade" on my Fedora there's a kernel update, and I can't make up my mind whether this is good (up to date) or bad (have to reboot). 🤔 npub15733wrmg24u9ja93crx7tnzdsvqnr2r9h4p5vrpde2w34ejx89yq8m6dhc Mauricio Teixeira 👨💻☁️🐧 Hey #SelfHosted #HomeLab folks: I'm looking for a photo app/server that can do keyword search similar to how Google Photos does.
