✨ The Full Stack by @codetv.dev is premiering THIS THURSDAY at noon PST / 3pm EST 🎉 Come for the coding, challenges, confessionals, & ✨ reality tv ✨ of building a product from scratch with @anand.io on camera while being judged by @kelseyhightower.com, @jason.energy, @darko.rup12.net & more!

Pausing my daily computer books post for this: A boxed copy of Microsoft Windows 1.0 😍 Definitely a product of the Year!

I'm posting one vintage computer book from my collection each day! 📚 Book 08: Principles of Distributed Database Systems from 1991 by Özsu and Valduirez! This looks like your typical sys admin book from the start, but it's so much more. Very much goes into the theory behind such systems!

I'm posting one vintage computer book from my collection each day! 📚 Book 07: The LaTeX Companion! Long time before Markdown was a twinkle in all our eyes, we had LaTeX (Pronounced lah-tek). Well, math and science people still have LaTeX! Also, book covers used to be way cooler in 1994.

I'm posting one vintage computer book from my collection each day! 📚 Book 06: First of the O'Reilly books! And the first thing I love/hated in web development - jQuery!

I'm posting one vintage computer book from my collection each day! 📚 Book 04: First of the "For Dummies Book" in this series, and yeah It's all about Visual C++ 6.0 here! I guess no time like the present to build those sweet sweet Win98 and NT applications!

I'm posting one vintage computer book from my collection each day! 📚 Book 02: The PC Configuration Handbook by John Woram! A 1990 specimen explaining how to actually build that PC. Even contains BASIC code showing how to get current ROM date on an IBM PC

I'm posting one vintage computer book from my collection each day! 📚 Book 01: 68000 Assembly by Gerry Kane, Doug Hawkins and Lance Leventhal. This book came out in 1981 and goes over programming that sweet Motorola 68K!

This was the peak of #vcfpnw on Saturday .. a much larger venue than the final ICF, but we’re planning for more next year! #vintagecomputing #retrocomputing #retrogaming

I’ve recently upgraded to an EV ❤️

Enjoying some vintage Japanese hardware with @thevowel.com at VCF PNW 😍

What is the most cursed storage system I could make? This is a RAID0 array running on 32 of the worst USB flash drives money can buy. 🤞 Right now, on top of it I am running an Amazon S3 compatible object storage system. Let's see how many 9s can I get!

Do you wanna see S3 Files in action? I got you! youtu.be/zb8TdNJhZCk

Finally! I saw a S3 Bucket experience a race condition!

If I can quote my good friend Cobus: I am getting ARMd and Dangerous! 😍 For a long time I wanted to experiment with running some Linux on ARM (beyond just a Raspberry Pi). And with the current day RAM and Storage prices, the Minisforum MS-R1 with 64GB of RAM and 1TB of storage at ~ $640 is a steal!

Come hang out with @kateholterhoff.com and me while we livestream with @darko.rup12.net We're live at 9:30 Pacific! www.twitch.tv/kirodotdev

In my computer collection I have plenty of interesting specimens! But none are as interesting to me as this old Yugoslav Pecom32 from Ei Niš! 😍 Running on a RCA1802 CPU, some West German Toshiba RAM chips, and all Made in Yugoslavia. Stay tuned for a full write up on this!

Weekend project: Display home lab rack power use! Using a ESP32 and a 1602 LCD, I extract power usage from my smart plug via MQTT! Kids, never do home labs! It keeps getting out of hand! 😅

Setting up a k3s cluster from mini PCs means replacing a lot of CMOS backup batteries!

Powered by ESP32 and some LEDs

Did you know that you can use the CLI and SDK to upload objects to other clouds!? This was a fun little experiment this weekend, where I got to upload files to Nebius's object store using my tools built for S3 buckets! rup12.net/posts/s3-api... #aws #s3 #sdk

Since the release of obsidian-sync has made my initial blog post outdated, I've decided to give a little update with the current instructions on how to setup a headless obsidian sync on homelab server! https://rup12.net/posts/running-obsidian-headless/

Implementing post view tracking: Commit messages tell a story

There is something special about this Pentium II server I picked from the trash. See if you can spot it at the end.

In my attempts to OptiplexMaxx I've given my nodes names based on rivers from my neck of the woods! 😍 Some servers are still pets!

I always keep my important backups close by!

Everyone is MacMinimaxxing for agents. Guess I should DellOptiplexmaxx!

How about a HP workstation for $18 😍 64 GB DDR4 ECC is the gold mine here

Running @obsidian.md without a GUI can be tricky! Well, with some virtual frame buffers and x11 forwarding, I made it work! 👏 Agents rejoice! With a future release of a CLI version, I hope that soon my post will be irrelevant! 😅 But do check it out here: rup12.net/posts/runnin...

A browser assistant I vibed up. Basically trying to have a web version of Kiro for my day to day tasks. Whats amazing about this is that is ALMOST ALL, just @htmx.org 🔥 The only non HTMX JS used is the SSE streaming and MD rendering and clipboard! Oh, and Rust 🦀

Spent the day learning/exploring/trying out Ratatui. As *the* TUI framework for Rust, it has always been quite daunting to me. But I've decided to give it a good go. And, it's amazing! 😍 I have some interesting ideas for my CLIs to have TUIs (now that everyone likes them again 💘) #rust #tui

Who wants to build a P(i)DP-8? ❤️

Did you know that mpv can play videos from the TTY? Using the caca (yes) Video output, it shows the video from ASCII characters! 😍 There are better options like tct, but I do love the look here! #mpv #tty #linux

Rust + WLED + JSON = 🚀⚡️🔥 I managed to get it down to 20ms 🤯

It’s been 26 years since the Intel 80286 came out! ❤️ Up to 25Mhz of pure speed (hopefully with a co-processor) ⚡️

Ran into this glorious Olivetti keyboard in my collection!

Last weekend I did something fun! I thought to myself “Can I get this 25 year old Sun Microsystems server online?” Better yet, can I have it host a website? 🤔 rup12.net/posts/can-my...

Got that Sun Ultra 60 out last night ❤️

Part 24 of DEV Track Spotlight 🦀 DEV405 with @darko.rup12.net (AWS Principal Developer Advocate) "With the world of LLMs, with coding assistants, with everything at your fingertips, you don't need to write Python anymore. You can write Rust." #AWSreInvent #DEVTrack #Rust

This weeks project: Build a Rust app which generates BASIC code that prints large letters like this in Hi-Res mode!

Holiday BASICs 💾

Let’s talk about Rust’s Result and Unwrap: youtu.be/MTFqc_XzkgU?...

Let’s learn some Rust together! ❤️🦀 Configuring the AWS Rust SDK youtu.be/3nupUNtQ77k

Another LGR Christmas thing! Watching/reacting/researching stuff in the Computer Chronicles Christmas Buyer's Guide from 1987 youtu.be/bWXLDfbmpU8 And that's it for both holiday videos and LGR overall in 2025. Have a happy new year and I look forward to getting back to more LGR things in January 🎉

It’s Friday evening, and I’m backing up a collection of 5.25” Floppy disks! Thank you IBM PC XT 😍
