It is not that complicated for now. It is an algorithm on a loop and someone started it

I think you are right, but he did also blog about it..

It is the whole bench-mining and fish-slop optimization. Seq2seq models are probably stable on their own, translating from my typo ridden prompts to code should be ok because it is natural to the tech

I am also rusting my hw. Last week my mouse, this week my EUC (wish me luck). I would rather risk a crash than memory corruption

Is this a summary made in the mist of the fray. I need a timeline

One thing I have to be honest about, and it's mine.. The one thing I would check before... do you want to do that? Say go an and will do it without the check While checking I found 3 vulnerabilities and 2 potential optimizations of which I fixed 2 and 1. Do you want me to file the other as issue, or stop for the day? We have done this morning. I feel you need a break

LinkedIn is also suppressive. The algo for maximizing non-confrontational screen time is strongly tuned against: critical posts and comments. Real bringing of information from outside the bubble. Links are severely suppressed.

Yes, but Λ < 0 would make it negative

Λ ≤ 0 in the intro. Great site!

New comment by arbirk in "Anger, Anxiety and Agency"

Anger is not productive. But we need to be more accepting to "the mood of the day". Winter grumpiness, being annoyed over having to bike in the rain, being able to show that you are stressed, weak, feel weird should all be emotions that we accept in the social space that is the workplace.

I live by "everything is grey". I am interestingly smart in some niche domains that I have a hard time communicating exists. I also insist on not fitting any template. Pretty dumb, right?

It is all about abstraction, and basic English is a quite bad abstraction

It is a matter of law. Only humans count as persons and citizens. Any robot that makes a decision defers accountability to its human owner.

Imo this point should be changed to reviewability. Beauty is in the eye of the beholder

I have been a fan of Ruby for many years, but in this fast paced era the Ruby ecosystem always struggled with the dependency versioning. Gems I relied on were never available or compatible with the rest of the ecosystem.

For family cars we need 4x 30-50 hp units. If the motor can weigh around 7 kg it can be placed directly on wheel. Adding durable brake discs (rarely used) and 2 inverters front ad back and we have the EV platform of the next 100 years
