Map, filter, and fold are higher order functions, functions which take functions as parameters. You are misusing the word callback. A callback is a function passed to another threa…

Regulation doesn’t mean it would be safer, just more bureaucratic. There are plenty of examples in the US of regulators failing to properly regulate like in Flint. Adding these reg…

The Romans or the Chinese?

In a functional language those details should be irrelevant. But of course they are relevant in practice, and map is usually just a for loop.

The thing about C++ is that you need to recruit specifically for C++ programmers in a way that you don’t need to recruit for programmers in many other languages. The barrier of ent…

Most stuff is web stuff now. And I’m not talking about front end, we do a lot of back end work in TypeScript because node is lighter than the JVM which makes it a better choice for…

C/C++ is not a language. I am also someone who has use C and C++ for years as part of my work and have mostly moved on to TypeScript because there isn’t much reason to use C or C++…

They don’t have to be glorified for loops, even if they usually are. Map and Filter should be capable of running in parallel or asynchronously, and some languages provide this.

That is a niche, because most applications are IO bound and not compute bound. What even qualifies as “systems programming” is ill defined. Far more critical business systems run o…

Java killed it for general purpose use in the 90s. It’s never your first option unless you are in areas like games, graphics, some embedded work, or quantitative trading.

By compiling you mean rewriting it in C or Cython. Which is only a good idea for certain applications.

Complex languages don’t result in better programs. Else we would see Scala and C++ everywhere instead of them being relegated to narrow niches.

Python has become less functional over time. It’s also not a particularly good OO language either. It’s really a more descriptive sort of bash that became ubiquitous despite its sh…

Nesting functions like this can have a bad performance impact because functions in Python are objects. Normally, all of those function objects are instantiated once when you load t…

Optimizing compilers are good at optimizing obvious code, so this usually isn’t a trade off. Many of the clever hacks you can find in books from the 80s are irrelevant now because …

Floats aren’t reals, at best they are an approximation for certain calculations. +0 and -0 are defined and distinct floating point numbers. Floating point math is known to be probl…

This is false. Integer division by zero is undefined, but floating point division is perfectly fine. Many languages have different operators to distinguish floating point and integ…

Infinity is a valid floating point number in the ISO standard. However integer division by 0 isn’t. div 1 0 will fail.

Because / is floating point division, and infinity is a defined value in floating point numbers. Try it again with div for integer division.

Apple has been selling laptops with broken keyboards for years, not to mention all of the other problems caused by insufficient cooling.
