astrojams··on How big are factorials?
I've struggled to understand how TREE(3) works and why it grows so big. I once posted to Math.Stackexchange many years ago and got a professor to help explain it to me: https://math.stackexchange.com/questions/313134/why-is-tree3...

I also loved David Metzler's series on ridiculously big numbers: https://www.youtube.com/playlist?list=PL3A50BB9C34AB36B3

astrojams··on Porsche sold more electrified cars in Europe in 2025 than pure gas-powered cars
I have a 2022 Porsche 911. It has a lot of physical controls for things in the cabin like climate control, suspension settings, cruise control, dashboard view, and audio. The car also has an auto steer and cruise control option which will accelerate and brake for you while also keeping the car in the lane. It can go from a stop to whatever speed you set it to. It’s great for traffic on the highway. That’s not too shabby for a 2022 non EV car. Current model Mercedes have level 4 driving automation where you can take your eyes off the road. I don’t think Tesla even has this level of driving automation yet.
astrojams··on Lessons from 14 years at Google
I’m a big fan of Amazon’s leadership principles. One of them is bias for action. I worked at AWS for a few years and I’d be in a meeting and someone would say bias for action and we’d all know what we needed to do.
astrojams··on Claude Opus 4.5
I find it hilarious that it rick rolled you. I wonder if that is an easter egg of some sort?
astrojams··on Beaver Drop
I live in Texas. It takes about 8 hours drive to get out of Texas regardless of the direction I go. That's just one state. Texas is the only state that has 8 different climate zones.
astrojams··on Show HN: Use your familiar Markdown editor to create and publish web pages
The blog didn't work for me. I just got a circle that spins forever.
astrojams··on How we plan to de-extinct the Dodo bird
Keystone species can be important to the overall environment and other animals. Bring back the right ones and you could improve the environment. https://en.wikipedia.org/wiki/Keystone_species
astrojams··on MacBook Pro featuring M2 Pro and M2 Max
I believe that the M1 architecture is such that you don't actually need as much RAM as an older model computer. It is a system on a chip so moving data between RAM and storage is so fast that it can swap between the two without much performance degradation.
astrojams··on NYC Slice
I grew up in NY and lived in NYC and I still call it a plain slice.
astrojams··on NYC Slice
As a person who also grew up in NY, the slice was part of my childhood. I'd walk home from middle school and then high school and pass the local pizzeria where I could pick up a slice, Italian ice, and play coin operated video games. Galaga, Donkey Kong, and Pacman. I miss those carefree days where the world was simpler and the pizza tasted better.
astrojams··on iPad Pro M2
Blink.sh is my favorite ssh app for the iPad.
astrojams··on Cloudflare announces fourth quarter and fiscal year 2021 financial results
It was their CTO who said that. Their CEO is on paternity leave.
astrojams··on Cocaine Paraphernalia Ads in the 70s
I would love to live in this world.
astrojams··on Macaques at Japan reserve get first alpha female in 70-year history
Wow this is fascinating. I'd love to read more about this, do you have any links to articles discussing this behavior?
astrojams··on HBO Max accidentally sent an integration email test to users
If this was a marketing ploy, it is genius. The amount of play this email is getting is ridiculous. Brilliant move if it was planned.
astrojams··on Stack Overflow sold to Prosus for $1.8B
I asked a question on math.stackexchange 8 years ago and that question got really popular and now I'm in the top 34% ranking of folks on the Math site. I don't really know a lot about math but people really like the TREE(3) function.
astrojams··on The Evolution of Hacker News (2013)
10 years for me. I still check it every day.
astrojams··on Email from Jeff Bezos to employees
I worked for AWS for a few years under Andy. He's a good pick for CEO of that company.
astrojams··on AWS Having Trouble Again
AWS usually does a post mortem where they inform what caused the problem and what they will do going forward to prevent it from happening again.
astrojams··on AWS Having Trouble Again
Here is the aws Dashboard: https://status.aws.amazon.com/
astrojams··on ReMarkable 2.0 – A digital notebook that feels like paper
Your comment just made me buy it. I didn't realize it was an open device running linux. That sold me. There are probably some marketing lessons to be learned from these comments.
astrojams··on Greensboro Man Creates Dating App Where He's the Only Guy Allowed
I have a friend who used to work for one of the bigger dating app services. He is an AI expert and wrote the matching algorithm for the service. He is very good at his job and his algorithm was so good that people matched, got married and stopped using the dating service. The higher ups in the company noticed the loss of revenue and asked him to make his algorithm worse so that people would match, date, but then break up and go back to their service. He proceeded to quit his job.
astrojams··on Ketamine has 'fast-acting benefits' for depression
My doctor uses a sedative also to make sure you don't freak out during the treatment. I think most doctors do this. You need to factor that into the cost too.
astrojams··on Why Jewish History Is So Hard to Write
This is great. I’ve dismissed my Jewish heritage and the teachings of religious texts, but this perspective gives me pause. Maybe I’ve been hasty in my assessment that religion doesn’t offer me anything for making a better future.
astrojams··on Tesla Autopilot 2 on Winding Local Road
The Tesla requires you to keep your hand on the wheel while in auto-steer mode. You can take your hand off the wheel, but the car will beep loudly after a while and if you don’t put your hand back on the wheel, the car will pull over and stop. It then locks you out of auto-steer mode until you cycle the power on the car.
astrojams··on TunnelBear Joins McAfee
I also had no problem cancelling my account.
astrojams··on Apple confirms it uses Google cloud for some of iCloud
It would make sense for Apple to continue to use both AWS and Google Cloud so that it maintains its negotiating powers with both vendors.
astrojams··on The Battle for Best Semi-Autonomous System: Tesla Autopilot vs. GM SuperCruise
I’ve got a Tesla model X and I’ve been in situations where the autopilot screwed up and required me to take over to prevent an accident. Most recently the car was autonomously changing lanes on a highway and didn’t see a guy on a motorcycle who was following too closely to the car in front of him. It’s probably an edge case, but still makes me weary of using it more.
astrojams··on Hype or Not? Some Perspective on OpenAI’s DotA 2 Bot
They play themselves. No need to play other bots.
astrojams··on The best defense against malicious AI is AI
Would strategies used by AI's that play imperfect information games like Poker be useful for winning a contest like this?
