I've been reading notsofast's article  about security. He said the safest way to run an altcoin wallet is to compile an open source code. Any guides how to do it? Is it called to run a client from a command line?

You can compile a wallet in ubuntu/linux pretty easily. It gets a little bit more interesting in windows though.

Simply google something along the lines of "Compiling bitcoin core from source {operating system X}".

If you're on windows you'll probably want to use something like MinGW

Not exactly. Compiling means turning the source code (the written commands) into machine readable code that a computer can run efficiently. It does involve typing a number of commands at your shell prompt, but you only compile a program once, after which you can run it any way you want. Compiling your own software is considered safer than running binaries compiled by others because the latter are more difficult to examine for back doors and other malicious features.

Even if you downloaded the source code, there's no guarantee that the code hasn't been tampered with. So, you would also have to verify the signature of the code. Especially given the countless altcoin wallets out there, you never know what to expect. Also pay special attention to the URL where you are downloading the wallet software from.
