They’re measuring program execution time, including program startup and tear down. Languages with a more complex runtime take longer for the startup, and all seem to have roughly equally optimized that.

I don’t see how that Wikipedia page supports your claim “The key concept in "parametric polymorphism", which is what programming language nerds mean by generics, is "parametricity"” . That page doesn’t even contain the

I somewhat disagree. FTA: “If the callsite is some_function(2);, the compiler resolves T as i32 and selects the corresponding branch, returning the value incremented by one. […] The important point is that the decision is driven entirely b

I think that, on the App Store, ads may be the least worse solution. Currently, some developers try to get into your view by creating multiple similar apps, as that gets them screen space for free. Given developers the ability to pay to hav

FTA#1: “Hashmaps do not (efficiently) support range queries. Since the keys are stored in pseudorandom order” FTA#2: “Object keys (think JSON) are hashed to a 4-byte digest and stored inside B-tree nodes” It still will likely be faster

> So there I was, implementing a one element ring buffer. Which, I'm sure you'll agree, is a perfectly reasonable data structure. It is, but, IMO, shouldn’t use the code for “a n-element ring buffer, with n set to 1”, similarly

Yes, they do, but if what goes in is insufficient by a wide margin, people who can afford to will start drilling for water. Assuming that the water taken through qanats would eventually make it into aquifers (fat from unlikely, I think, as

Yes, you can. The problem with testing is that a candidate treatment may make things worse for patients, not that it may improve things. If your treatment works, that’s an improvement of what you had before. Once you know that, you can trea

From what I read here, the problem is that EVIL.app can read your git tokens, too, without you having anything to say about it. Yes, you want a system that allows sharing of those tokens between various tools, but you also want the user t

For selfies, I think iPhones with Face ID use the TrueDepth camera hardware to measure Z position. That’s not full camera resolution, but it will definitely help.

It not warm as in ”warmer than the typical living space”, but it is warmer than zero Kelvin, so heat can be extracted from it. Doing that takes energy, that’s why it is called a heat pump . That moves heat from the water to an already warm

Some of those could be partially fixed in hardware. Examples: - returns can run in as good as zero time - when calling a word, the CPU could prefetch the cache line containing the next word to be called, on the assumption that it would be c

A disadvantage of git add -p is that it allows you to create a commit that never existed on the development system, and, hence, cannot have been tested. How do people handle that? One way would be to follow it up with git stash , running

On the one hand earthquakes remove tension from the earth’s crust and release energy that can’t be used in future shocks. On the other hand, if a shock doesn’t release all energy it may come to rest in a relatively weak spot that will soon
