Learned about Chris on after midnight with Taylor Tomlinson. Absolutely unhinged but quite funny 😂
This post about "Respectful Open Source" by @andrewnez.bsky.social inspired me to have Claude build forkwatch, a tool that analyzes forks of any repo and highlights where multiple forks converge on the same fix.

Just posted about a fun weekend project to improve my home network security and the entire project was just me having a few conversations with AI agents. jonmagic.com/posts/securi...
I joined the No Kings protest in San Mateo California today and walked the two miles from Hillsdale Mall to Central Park with hundreds (maybe more). It was encouraging to see everyone with their signs, their voices, exercising their rights, and hear the cars honking their horns in solidarity.
According to eyewitnesses, armed ICE agents dragged kids out of their beds in the middle of the night, zip tied them and put them in rented vans while raiding an * entire apartment building* on the South Side of Chicago.

"Tyranny requires constant effort. It breaks, it leaks. Authority is brittle. Oppression is the mask of fear. Remember that."
Looking forward to seeing Jimmy back on the air.
I stand with Kimmel. I stand for the right to free speech.

Some musings on how designing collaborations is providing more value than building automations for me at work these days. jonmagic.com/posts/design...
I just finished rewriting a post I first published for coworkers inside GitHub a few months ago so that I could share it with you 😀 The past few years but especially the past few months I've transformed the way I work to leverage transcripts, prompts, and LLMs and I hope these tips can help you too!
This week as the last RailsConf takes place I reflect on how Rails led me to a career in software development, from the first RailsConf in 2006, joining OrderedList in 2010, being GitHub’s first acquihire in 2011, and 13+ years helping build and protect it since. jonmagic.com/posts/farewe...
I’m blogging again and doing even more open source work as I try to contribute to the collective brain. jonmagic.com/posts/the-un...
Was going to do 5k, then 8k, and then pushed even harder to make it 10k because everything was running smoothly. Had no idea I was on track to PR but I did go all out last block just in case.
New 10k PR today! It’s been many months since my last PR. I think the combination of colder weather and sweatpants plus headphones were holding me back. Today I decided to switch to shorts and take out the headphones right before I left the house and it felt fantastic.
I’ve worked in this department for the past 8 years and have seen it expand from just 4 of us focused on spam and abuse to nearly 30 on all the areas I mentioned above.
I love to talk tech, running, and food and have mostly been over on Threads the past year but checking this community out next.
Hi, I’m jonmagic on the interwebs 👋🏻 I work at GitHub (13 years today!) and just accepted an offer for a new role as a principal engineer for our Safety and Integrity team focused on stopping abuse@scale and supporting the Trust & Safety and Privacy teams at GitHub with engineering work.
Today, GitHub announced a Secure Open Source Fund aimed at supporting and enhancing the security of open source software backed with +$1.25MM in funding from partners.
