How to define hash tables in Bash?
...n for very large hash tables. You have to enforce key uniqueness yourself, etc. Even if you only have a few hundred entries, the output file/grep combo is going to be quite a bit faster - in my experience several times faster. It also eats less memory.
Here's one way to do it:
hinit() {
rm -f ...
How to specify new GCC path for CMake
...s checks on the compiler: Does it work? Is it able to produce executables? etc. It also uses the compiler to detect related tools, like ar and ranlib. When you override the compiler value in a script, it's "too late", all checks and detections are already done.
For instance, on my machine with gcc ...

... target.Read = source.Read;
target.ReadRule = source.ReadRule;
// etc
}

How does a public key verify a signature?
...ey.
A digital signature in its simplest description is a hash (SHA1, MD5, etc.) of the data (file, message, etc.) that is subsequently encrypted with the signer's private key. Since that is something only the signer has (or should have) that is where the trust comes from. EVERYONE has (or should ...
Immutable vs Mutable types
... bytearray()
set type: set()
mapping type: dict()
classes, class instances
etc.
One trick to quickly test if a type is mutable or not, is to use id() built-in function.
Examples, using on integer,
>>> i = 1
>>> id(i)
***704
>>> i += 1
>>> i
2
>>> id(...
