What does Expression.Quote() do that Expression.Constant() can’t already do?
...xtremely confusing and bug prone.
Long answer:
Consider the following:
(int s)=>(int t)=>s+t
The outer lambda is a factory for adders that are bound to the outer lambda's parameter.
Now, suppose we wish to represent this as an expression tree that will later be compiled and executed. Wh...
How do I set default values for functions parameters in Matlab?
... to work with such property/value pairs, parse_pv_pairs.m. It helps you to convert property/value pairs into a matlab structure. It also enables you to supply default values for each parameter. Converting an unwieldy list of parameters into a structure is a VERY nice way to pass them around in MATLA...
How to sort List of objects by some property
...esComparer implements Comparator<ActiveAlarm> {
@Override

return startComparison != 0 ? startComparison

Are static fields inherited?
...
3 in all cases, since the static int total inherited by SomeDerivedClass is exactly the one in SomeClass, not a distinct variable.
Edit: actually 4 in all cases, as @ejames spotted and pointed out in his answer, which see.

How to use C++ in Go
... linking a small test C++ class with Go
If you wrap you C++ code with a C interface you should be able to call your library with cgo (see the example of gmp in $GOROOT/misc/cgo/gmp).
I'm not sure if the idea of a class in C++ is really expressible in Go, as it doesn't have inheritance.
Here's an...
Split data frame string column into multiple columns
...ing columns will have correct types and improve performance by adding type.convert and fixed arguments (since "_and_" isn't really a regex)
setDT(before)[, paste0("type", 1:2) := tstrsplit(type, "_and_", type.convert = TRUE, fixed = TRUE)]

How to read a file without newlines?
...t would help in some circumstances, on my system \r\n line endings are not converted to \n, whether read as text or binary, so os.linesep would work where \n does not. But splitlines is clearly the better choice, in the case you mention where the file does not match the os. Really I mostly mentioned...
Default initialization of std::array?
...zed array of objects with such types will have indeterminate value, e.g.:
int plain_int;
int c_style_array[13];
std::array<int, 13> cxx_style_array;
Both the c-style array and std::array are filled with integers of indeterminate value, just as plain_int has indeterminate value.
