“You don’t change. You change the perception of yourself” - George Hotz

I understand believing in God because of the alternatives, but why Christianity? How did you get from God to Jesus is the son of God? Don't you need evidence for that? I ask this as someone who used to be a very devoted Christian. The thought process that leads to Christianity is not at all predictive of truth. Like many other major religions, the premise is that you have to believe the least likely explanation. That's what a miracle is - the least probable explanation. Even if you believed in magic, would it be reasonable to assume that a particular magician is magic just because you couldn't think of an alternative explanation for their trick?

man i have no idea what any of this stuff means.

Sooo lets write a 3090 driver for ms dos ® sir you are a legend a major glitch in the matrix. Keep up the good work. Nothing you cant do

these streams have been a delight and intellectually stimulating, a rarity on the internet, thank you George. You've inspired me.

Has geohotz stopped using vim or? I noticed the past few months he now is using vscode? 👀

Help me out boys, did George code Quentin himself? If so I was looking for the video to see this done.

Is there a way to find out ahead of time roughly when george will be streaming. I'm in Aus so back to front timezones but would love to catch a live stream.

4:19:38 Christ has indeed died for your sins. Mine and yours alike

What is the general software skillset needed to work on low level projects like tiny grad ? C, Python, Assembly & Machine Learning? I'm currently working on Machine Learning, C, Python and building kernels(with minimal Assembly skills).

Biggest bag of bullshit to say: I want to work for/with you but I don't want to contribute/gather experience about the literal thing the company does. 😂 You putting in so much work, I can understand your anger. I'd honestly just ignore such people. If someone's life purpose amounts to just earn enough to live a very good life, then what is the purpose at all, right? "Not having time" is the most bullshit excuse for men in ther 20s-30s - unless they have children.

People were asking George like he is an AGI Lol

Learning HTML ans CSS them boom i see this kinda video.. Should this be a motivation or a reason to give up coding lol

I have a question. I saw that he hooked the native function "ioctl" function. But replace & sniff this function for what? I don't know what is the final purpose. Can you make it more clear? Thanks.

George stop using that keyboard and put voice to AI to code those things, it takes too much time that way. Use on the code editor some AI engines.

i learned html and css and iam about to learn js n php can any one tell can i upload my website for free or it is paid before i waste my time learning idonot habe aa credit card

hey George if we humans had more food in the planet we would live longer😊 like 200 years supply of food for the beings on the planet would be enough. there is a lot of waste in the process😊

Super Informative, why don't you choose pycharm?

The things I would do for a brain like his, dude is a machine.

Another topic I kept hearing during Covid era, besides cloth masks and 5G, was chemtrails.

trying to define yourself is like trying to bite your own teeth

Great content, thanks, it helps me to focus while I program stuff

Did You just crack a beer and write a gpu driver ?

maybe he will read comments next time. neurotrasmitters and electrical signal are not separated systems. neurotrasmitters transmit signal between neurons. hance the name. an electrical potential is then sent only internally to the neuron. hopes this helps.

This is how i feel when I set a ip on one of my vms LMAO

Did he ever answer what to do if you fall under category 2 at 3:49:49

He doesn't even know what viscosity is. PPC.

guys what is this font and size he use in vscode?

submitting once then resubmitting twice so three times

"thank you regex 101 guy - I like you" lol

Another great stream, thanks for doing these George

what mouse does he use? the click sounds so soft

Can someone tell me why George choose Plexity AI instead of alternatives like ChatGPT or Github Copilot?

4:13:17 im going to tead this book tonight thanks geohotz

how do I learn driver programming?

George LOVES Qualcomm, that's why he's working with their hardware :) Way to go, George!

strangely enough, i keep coming back to your stream, as it is the most productive stuff i encounter in my everyday

watching this is like like wandering the old roads of greece pondering deep philosphy i thank you mr george you are a saint

What if your passion is stupid 😓😓

Why all this crazy stuff in Python ? Prototyping only ?

This guy codes

Sorry to ask but what os is he using

hello world

Golden video

keep on Hotzn' it!

What would your take be on scripting

yo does anyone know what keyboard george uses?

Boring!
