Why is there no GIL in the Java Virtual Machine? Why does Python need one so bad?
...
The JVM (at least hotspot) does have a similar concept to the "GIL", it's just much finer in its lock granularity, most of this comes from the GC's in hotspot which are more advanced.
In CPython it's one big lock (probably not that true...
Default function arguments in Rust
...
If you are using Rust 1.12 or later, you can at least make function arguments easier to use with Option and into():
fn add<T: Into<Option<u32>>>(a: u32, b: T) -> u32 {
if let Some(b) = b.into() {
a + b
} else {
a
}
}

iPhone App Icons - Exact Radius?
...factory designer) and all the answers so far on this post are wrong (or at least incomplete). Apple starts with the 57px icon and a radius of 10 then scales up or down from there. Thus you can calculate the radius for any icon size using 10/57 x new size (for example 10/57 x 114 gives 20, which is t...
Difference between a Structure and a Union
...foo;
long bar;
double baz;
long double quux;
}
allocates at least (sizeof(int)+sizeof(long)+sizeof(double)+sizeof(long double)) bytes in memory for each instance. ("At least" because architecture alignment constraints may force the compiler to pad the struct.)
On the other hand,

Is short-circuiting logical operators mandated? And evaluation order?

Storing money in a decimal column - what precision and scale?
...The rule of thumb for storage of fixed point decimal values is to store at least one more decimal place than you actually require to allow for rounding. One of the reasons for mapping the old Currency type in the front end to DECIMAL(19, 4) type in the back end was that Currency exhibited bankers' r...
Is the 'override' keyword just a check for a overridden virtual method?
...thod on the base class. The overriding method must have same signature (at least for the input parameters) as the method it intends to rewrite.
Why is this necessary? Well, the following two common error cases are prevented:
one mistypes a type in the new method. The compiler, unaware that it is ...
How do I send a JSON string in a POST request in Go
...n this be updated to gather / inspect all it's errors? This is (for me, at least) the top result on google for making post requests in Go, and it's a good answer, but I see a ton of example code that just ignores errors, and I think it encourages bad practice in newbies. Then again, if anyone regul...
What to do about a 11000 lines C++ source file?
...ng refactoring process, you could leave this big file as is for a while at least without adding more code to it: since it contains one "main class" you could inherit from it and keep inherited class(es) with overloaded functions in several new small and well designed files.
