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 😍

Part 5 of DEV Track Spotlight 🦀 DEV307 with @ajs.bsky.social (AWS Serverless Hero, Datadog) & @darko.rup12.net (AWS) Amazon Aurora DSQL: Kotlin devs rewrote one component in Rust → 10x faster with ZERO optimization attempts! #AWSreInvent #DEVTrack #AWSCommunity #AWSHeroes

Find someone that looks at you the way @ajs.bsky.social looks at @darko.rup12.net.

Something very special came in a box 😍

Yes, you CAN write MCP Servers in Rust 🦀 Here is my adventure in writing one: rup12.net/posts/write-...

What the hell is this weather NYC?! 😱🥵

Introducing Kiro - I've been testing it out for a while. It's truly a game changer. Spec-driven development and agent hooks are a new paradigm in AI-assisted development. Check it out! 👻 kiro.dev

Quick trial of AWS new IDE called Kiro, compared to my current favourite tool - Claude Code.. I gave the same task to Kiro and to Claude Code. First and foremost, I love how Kiro makes requirements > design > build a first-class citizen. That's by far the best workflow at the moment, and making...

Well, this is awkward. AWS released a Cursor clone and it's... actually not terrible? It may be time to re-evaluate my life. kiro.dev/blog/introdu...

I'm feeling spooky today! 👻

For this weekend! I have unopened copies of something vintage from our friends over at Microsoft 😍 Microsoft Excel 2.1 and Microsoft Windows/286 ❤️

I thought we were ready for Wayland. I'll try again in 6 months!

Can you smell these old manuals?

What a way to end a week! Got my hands on a couple of Data General One laptops ! 😍 These (unfortunate ) laptops from the mid 1980s were quite one of their kind! A Minicomputer manufacturer making personal laptops? Preposterous 🤯 Expect an unboxing and demo video soon! ❤️

Grilling never stops 🥩🔥

Weeks worth of chicken! 🔥

Whoa! 🤯 2000 subscribers on my YouTube channel! Thank you so much for checking out my content there 😭😍

I did not know that Blind is *so racist*. The amount of hateful comments, talking crap about foreigners, visa holders, "they took our jobs" is scary! As a visa holder myself, I am truly appalled by the fact that my colleagues in tech have such a shit opinion of us. Goodbye Blind! 👋

Do you use zsh? Did you know you can make it even better? 🤔 In the video below I go over three tips…tools? Whatever , I use in my zsh configuration that save me those precious keyboard taps! dotfiles linked in the video ❤️ (Bonus: a kitty 😻) youtu.be/llVsxmcOlwo?... #zsh #linux #commandline

As I was recording a video last night, I had a fuzzy guest join me! 😻

New blog post where I look at some new experimental features in Amazon Q CLI that can help you manage your context window. dev.to/aws/manage-c...

🔥 Just dropped a deep-dive on building MCP servers with Dart for the Flame Engine! You will learn how to build MCP server both with AI assistance AND manually with full explanations. Perfect for Flutter game devs who want AI that actually understands Flame and more! 🎮 Full blog: bit.ly/4nwVtUM

I could really use your help looking for Senior++ Technical Writer roles or intermediate++ Developer Relations roles. I'm looking to stay in Germany. I'm also considering building up a freelance pipeline but realistically full time work makes my visa situation way easier. Please RT for reach 🙇‍♀️

☝️ zsh pro tip: If you are using 'vi' mode in Zsh, and want to edit your current command using your $EDITOR, these three lines in your .zshrc will enable you to do so by hitting `Esc` + 'v'

Did you know that Amazon Q Developer CLI is written in Rust 🦀? Take a peek at behind the code: www.youtube.com/watch?v=6lG0...

Finally set up my little retro corner 😍 Should be a good backdrop for videos!👏

Rust 🦀 + Postgres 🐘 + sqlx compile time queries = ♥️ If my SQL is wrong, the compiler actually catches it! 😍

🚀 New AWS Bites episode! We tried Amazon #DSQL so you don’t have to (but you might want to) 👀 Luciano and Eoin put Aurora DSQL through its paces in #AWS Bites #Podcast Episode 145 🧵 Here’s what we found:
