It drives me crazy how so many people (of all ages) can't do basic math in their head, at least approximately. You need it constantly and it's so much faster than picking up your phone, starting the app, and typing in the operatio

Nowadays, with uv (and probably some other tools too) it's pretty easy to ship a python program on a machine that doesn't even have python on it, so it's pretty much a solved problem today (in most cases). But 5 or 10 years a

> "making a folder" and "putting a ... main() func" in it You can't do that with python for instance. First, you need a python interpreter on the target machine, and on top of that you need the correct version

The biggest source of incompatibility isn't in the programming languages. It's either in the specifications ("hmm maybe one byte isn't enough after all for a character, let's break all those assumptions") or in

Unless you want to improve your ratio of paid-to-free users and change your userbase in the process. They're pissing off free users, but pros who use the paid version might like this new version better.

I'm not saying it was happening here, I'm just taking this anecdote as food for thought. I'm appalled to learn that those vehicles don't have an emergency stop system. A real emergency stop. Not some remote-controlled

As a teacher, I have a program I've been using for the last 8 years or so. I distribute the compiled version to students for them to compare their own results with what's expected. The program's written in go. I update it eve

This is so true. If I was only allowed to keep a single electrical device at home, it would be my washing machine. If I want to exercise, I'll go for a walk while the machine magically washes my clothes, thank you very much.

Yes. AFAIK "Table wine" (and table beer in northern regions) was pretty light. Just enough alcohol to kill germs.

Nope. Lunch time isn't part of work time so I don't see why the employer would even care.

You can also switch runtime checks off in Ada. The difference is that, in Ada, the default is to have them on, while in Rust, they are off by default.

Ada also has decimal values. I don't understand why all languages don't have them. Floats are a PITA when dealing with monetary values.

"0 people live within 5 km of Warsaw." (actual value is close to 2 millions). "80.000 people live within 0 km of Paris." (ditto, 2 millions live there). There are many other cities where the numbers are absurdly wrong. D

Well, turns out the CEO of Orange back then was Thierry Breton, and indeed nowadays Mr. Breton is a European Commissioner, so things turned out pretty well for him.

The issue is that intelligence itself is an ill-defined concept, and an unofficial but broadly-shared rough definition is "what separates humans (and some animals) from unanimated things". So, as soon as a machine can do something

It's often a modeling issue. Modeling languages are so abstract and general they give up a part of the problem's structure. The most famous example is the pigeonhole problem, when given to SAT solvers. Definition of the problem is

If you do that, malicious writers will have bots buy their books, get the precious "verified review" badge (and bumping the book's ranking at the same time), and give the book raving reviews. At that point, it just becomes an

But then that means goodreads wouldn't be a platform for readers anymore. It would be a platform for Amazon customers only. We already have amazon.com for that. What would be goodread's added value?

Average return is a metric, but it's not the only one. If you really want the biggest possible CAGR and don't care at all about volatility, you won't beat a 100% stocks allocation. Browne allocation's Sharpe ratio (0.67)

I myself tend to lean toward stock-heavy allocations, but this is not something I'd recommend to everyone. I don't know if you remember the 2008-2009 period, or if you even were an investor back then, but those were... interesting
