What inference provider are you using?

If it doesn't matter I will just pick the cheapest to run (the static ones).

We also use technology to care for the people in medicine and it requires pretty advanced science and engineering. Doesn't that shred your argument?

OP was talking about this: https://www.math.uwaterloo.ca/~hwolkowi/matrixcookbook.pdf

Look into some examples of the section 2.4 "Derivatives of Matrices, Vectors and Scalar Forms"

I took it in good faith I just think that:

- the overregulation narrative conflates two different problems

- and that you minimized too much the consumer benefits of EU legislation

I think the overregulation problem olis less that we have 200 EU regulations and we need to hack and slash 100 of them and more that we have 100 national regulations 25 are exact transcriptions of EU directives, 25 are transcriptions with tweaks and the other 50 are national scoped regulations and what we need to do is to make them uniform so that companies don't have to deal with 27x75 problems.

I'm a bit burned by politicians using the overregulation narrative and then not specifying a single example of a meaningfull rule that they would get rid of. Usually what is left in the air is that worker rights and consumer rights should be cut.

Do you believe I can't get a list of 20 effective pro-consumer regulations drafted by the EU out of Gemini?

This was an half usefull joke. I can still make it with the exterior unit off for an extra 1 or 2 degrees with just the interior unit blowing during the day and the use the AC to cool during the night when it is more efficient.

In any case where I live fans are not a meaningfull stopgap measure.

You can use your AC as a fan when it is not too bad.

> A very personal view but many developers/engineers fail to see the overall picture. And yes, I was there and I went through all of the mistakes.

What is failling to see the overall picture? I hate this overall picture mysticism. I bet that if people where given the same role and information as the CEO they would be able to see the overall picture.

Sorry to bother but is there hope we are going to see Practical Math for Programmers published any time soon?

Is this the book you are referring to? https://epubs.siam.org/doi/book/10.1137/1.9781611977448. It has 991 pages, not exactly what I would call concise.

What large parts of the world? Some places in Canada, the US, an handfull of countries in Europe, Autralia plus a few hotspots in SEA?

Sure in the US. But people are throwing token caps in 500, 1000, 2000 dollar range here. That is a very significant expense on top of salary, taxes and benefis. It's only justifiable if they observe 20% 30% or more productivity increases across the board.

If you have huge salaries, yeah sure 500 dollars its okay even if you only get 5 10% more productive.

You have people in Spain and Portugal hiring juniors at 25k per year.

I took into account all of that. Still ridiculous.

10 grand a month for a junior is absolutely ridiculous in most of the world including large swats of the western world.

For someone who has not tried these desktop apps: what is the the advantage versus cli codex with some MPCs and multiple folders each one with their context files?

Even if you get a crispy set of requirements from all parties you are still responsible for implementing all of then while making sense of the existing system (and from my experience significant issues arise at this stage when the full extent of requirement implications ia better understood). On top of that you might also be responsible for operating the thing, participate in compliance doc writing and do ongoing maintenace.

I'm also surprised. In Portugal primary, middle and high school tests and exams are all proctored and the vast majority of them written by hand.
