Honestly the only good use of Leto I’ve seen in what has proven to be an astoundingly durable career. Consistently the worst part of everything he does, yet somehow continues to work. And that docu-drama was so good I still think of it every time I use the WeWork in Glendale.

Unpopular opinion, but I think it’s good to practice empathy even towards people who don’t practice empathy. (I say “unpopular” bc they crucified the first guy who built a platform on that)

Hi Alexander! I’m afraid my pinned joke may have given you the wrong idea about my identity; the last bit about “with a different face for some reason” is more or less a “/s” tone indicator. I’m a different software engineer with the same name. :) people love that guy’s work though!

I was floored by the AirPods translate functionality… wonder how well it works outside of marketing material? Felt very Star Trek as advertised

Oh yeah, have a blast, love the chatbot as a chatbot, I was more referring to coders writing auth systems using agents and expecting them to pass any kind of audit

I wonder if maybe Cracker Barrel is to Christmas trends what Milan is to fashion trends. Maybe all the grandparents go to Cracker Barrel on Sep 1st like designers go to Italy in 2025 for what they’re gonna sell at Target in 2026.

So I lost a day of focus and productivity at work calling every pharmacy in town; no one will pay for that but me. Oh well. Not as frustrating as some have it… and I’m far from the first to say it. but: I’m not a fan of the current system. We should improve society somewhat.

ADHD meds are controlled substances; meaning you can still get them with a doctor’s prescription, but are legally required to be inconvenienced several hours per month when picking them up. (my old pharmacy got sold to a new owner who “doesn’t sell narcotics”; 24 hours later I have a new pharmacy)

Imagining leading a new employee orientation, but all of the employees are bots who keep telling me what a good job I’m doing… while completely failing to grasp anything else I’ve said (which tbf is not that different from regular human onboarding)

Split your format and lint jobs so they can run in parallel, independently of your test and build jobs

Other people in my peer group may have families, communities, and their mental health, but last month I reduced my team’s CI from 35 minutes to 7, so who’s **really** winning the game here

We were thinking through dependency configs specifically… we have lots of internal, interdependent packages, but if a dev removes a crate and doesn’t update the config, we get an error in CI. Here’s a sample repo that can generate a config, still pondering when to run github.com/johncarmack1...

Jacob! I'm so glad you posted this, it's how I found your profile! We use covector at our company (www.flightscience.ai) and I love it! Releases & PRs are so fast and convenient. Was wondering today: do you know of any projects that have successfully automated creation/maintenance of config.json?

It’s really funny how Vince Gilligan cast the perfect Gus Fring—a man so unassuming and even-tempered he fits right in as the New Mexico Dave Thomas—and a decade later casting Giancarlo is shorthand for “hey this is the bad guy”

I think about this comic all the time.
A panel from a Calvin and Hobbes comic.  Calvin's mom, eating dinner, says "Life could be worse, Calvin."  Calvin, clearly upset, his mouth huge says "Life could be a lot BETTER too!"

I just created a quick map depicting which portions of the United States are now (as of today) or will imminently be (by early June) without 24/7 local National Weather Service coverage (per Washington Post reporting). #CAwx #CAfire #CAwater #ORwx #AKwx #WYwx #KSwx
Map of local National Weather Service office "areas of responsibility" modified (using polygons with black outlines and red fill) to indicate where recent/expanding cuts to NOAA/NWS have resulting in understaffing so extreme that some offices can not longer operate on a 24/7 basis.

Generative AI hallucinating makes it completely useless for the thing we want it to do but people are using it for that thing anyway and that is terrifying

I have contributed code to Tauri, written multiple VC-funded apps in Tauri, and made a handful of plugins for Tauri…I could not agree more with this take on it. Managing the types for the IPC layer feels like my second job some days. With tauri-specta it is SO CLOSE… but not there. Maybe in 2025.

I see a lot of “AI is replacing engineers” hype, but the one company that actually tried replacing me with an LLM lost so many clients they went bankrupt in less than a year.

I used up all my social capital warning people about Trump the first time. I’m so isolated and burned out now, the only goal I hope for is survival. Idk why I bother with vulnerability on the open internet; it requires empathy and/or intelligence to respond well. Litmus test, maybe.

LLMs are a great tool, it’s like if I had a shovel that hit **just** to the left or right of where I was aiming, and sometimes shoveled some dirt on the third or fourth try!

Worried about losing access to US federal data that may go off-line, or already is? You’re not alone—but duplication isn’t the answer. Many ongoing efforts have already archived key datasets and many more are ongoing. Check out these existing resources and, if you can, support their work. 🧵

That video made me laugh so hard so many times. The running gag she made of the column blocking her view, which has since became a meme in its own right, should be taught in theater, philosophy, and business schools.

I grew up around airplanes. My dad flew us to family gatherings in his Beech Baron. I landed my first touch-and-go in a Cessna 152 at the age of 17. Over decades of flights, I never felt safer than when in the hands of air traffic control. I wonder if tomorrow I’ll finally stop crying.

In retrospect, the least realistic part of Tomorrow Never Dies was the part where intelligence agencies like MI6 and the CIA would be directed to **oppose** global chaos, rather than architect, engineer, and implement it themselves.
