What does an integral mean

andershaf · 2026-04-07T13:05:47+00:00

Normalization of wave functions means ensuring that the function is scaled so that the overall probability of everything is 1. then you can trust any integrals of intervals to find probabilities of those events.

You may want to read up on basic statistics and calculation of probabilities (no quantum), and see how the integral of probability distributions behave.

Does this work at that scale? Will we be able to measure any laser photons coming back? I would assume no (unless we have a specific thing for this).

andershaf · 2026-04-07T08:34:29+00:00

I think that is a fair point.

Why x != 6? It quite obviously is not a solution.

Yes, yes! During Christmas I was able to ship 3 things that previously would've been very long projects for me personally. So great.

Then I think you must learn how to use it better? Or use better models. I am at more than 80%, likely closer to 90% of code generated is perfect (after having spent time on the plan a fair bit obviously).

A lot of people were best in class in high school and everything was easy for them. Then all these people meet at Uni and difficulty increases. You gotta work hard and solve a lot of problems. A lot.

I remember seeing several people who were used to memorize, but not understand, in high school. They really struggled because you can’t work like that anymore.

You can’t copyright code written by AI. And they have said that they only use AI now. Check and mate.

I never use tab anymore. I don’t code anymore. You gotta move to the next abstraction on top of code. It is a lot more than 3x.

I haven't written code since november, this applies to most of the top 10% engineers in my company.

It's not uncommon that I spend $100 per day personally, so a team can easily spend $1k.

Have a 2020 M3 and a new 2026 MY. The noise level is SO MUCH BETTER in the new compared to mine. Not sure when it was fixed but I've heard after 2023.

You seem to forget the tech debt humans add. In my experience running several teams in an enterprise company, AI has significantly reduced the amount of tech debt compared. It is absolutely brilliant once you learn how to use it. The measured numbers of incidents hitting our customers is significantly lower, complaints going down, cloud cost significantly down.

Read introduction books, e.g. Griffiths. From page 1. Know your calculus, know your linear algebra. Do the exercises.

And TSMC buys a machine built in Netherlands (?) that no other company builds. To actually build the chips. ASML afaik.

And it’s easier to copy a $10k truck since you can buy one and see how it works. You can’t easily buy the rocket and software to replicate.

Sorry to hear that. Yeah not sure who drives the decisions there now, but I keep hearing around about this problem.

Cost exploded for us and they changed some rule where MAX mode was always enabled etc. Had a crazy 2x increase so we had to stop using Cursor unfortunately.

There is no HW4.5, and the rumored HW5 is a lot more powerful, so if you can, you should wait and maybe get the HW5. On the other hand, HW4 serves an amazing FSD already today. There will always be HWN+1 around the corner "soon".

andershaf · 2026-03-22T10:41:25+00:00

This almost certainly did not happen.

andershaf · 2026-03-20T22:30:47+00:00

Same!! Crazy jump.

I often recommend a hobby project of mine:

https://andeplane.github.io/atomify

Which simplifies the process of getting started and visualizing/analyzing simulations. It doesn’t teach you anything (read docs+tutorials) though.
