Generate random numbers uniformly over an entire range
...n, but for a serious application, you should take something better - or at least check its properties (uniform distribution is usually good, but values tend to correlate, and the sequence is deterministic). Knuth has an excellent (if hard-to-read) treatise on random number generators, and I recently...
Why does Python use 'magic methods'?
...
Python and the Principle of Least Astonishment is a good read for some of the advantages to Python being this way (although I do admit the English needs work). The basic point: it allows the standard library to implement a ton of code that becomes very,...
Why is Swift compile time so slow?
...ly don't understand why there is nothing like that in official sources (at least easy to find), for example the article you mention should (must!) have the remark about -Onone. We can not use whole module optimization for now because it makes compiler crash... But your advice gives almost x10 boost ...
What is the advantage of GCC's __builtin_expect in if else statements?
...in mind, the compiler can optimize the conditional so that it requires the least amount of work when the expected condition holds, at the expense of maybe having to do more work in case of the unexpected condition.
Take a look at how conditionals are implemented during the compilation phase, and al...
Passing arguments to “make run”
...e can you go in terms of readability and debugability and the Principle of least astonishment.
workaround: don't do this!!1 instead write a shell script that runs make and then runs prog.
i have only tested using gnu make. other makes may have different behaviour.
TL;DR don't try to do this

Why do some claim that Java's implementation of generics is bad?
...; may seem weird/redundant at first but is actually pretty interesting, at least within the constraints of Java/it's generics. Enums have a static values() method giving an array of their elements typed as the enum, not Enum, and that type is determined by the generic parameter, meaning you want Enu...
Cosmic Rays: what is the probability they will affect a program?
... is bad About a third of machines and over 8% of DIMMs in our fleet saw at least one correctable error per year. Our per-DIMM rates of correctable errors translate to an aver- age of 25,000–75,000 FIT (failures in time per billion hours of operation) per Mbit and a median FIT range of 778 – 25,0...
Convert List to List
...
If you use IEnumerable instead, it will work (at least in C# 4.0, I have not tried previous versions). This is just a cast, of course, it will still be a list.
Instead of -
List<A> listOfA = new List<C>(); // compiler Error
In the original code of the questio...
What's wrong with cplusplus.com?
... too pedantic / too technical; it is obvious that cplusplus.com employs at least a few technical editors who keep the pedants at bay. We'd have to keep the information well-organized; the FAQ here are not well organized. We'd also have to be very careful not to spout too much directly from the stand...
Differences in boolean operators: & vs && and | vs ||
...explain is correct, but the reasoning you state does not seem so, to me at least..
