Small python console script to check whether your password has been leaked to https://haveibeenpwned.com/ . See https://haveibeenpwned.com/API/v2#SearchingPwnedPasswordsByRange on why this is safe to do and you aren't leaking your password by checking.
#!/usr/bin/env python3
from hashlib import sha1
from getpass import getpass
from requests import get
def is_pwd_pwned(pwd):
""" Returns tuple of (pwned:boolean, occurances) for given password"""
h = sha1(pwd.encode('utf-8')).hexdigest().upper().encode('ascii')
prefix_h = h[:5]
suffix_h = h[5:]

MetaParams::typeCheckedFromSettings specialization for size_t in case I end up needing it one day (Mumble code)
template <>
size_t MetaParams::typeCheckedFromSettings(const QString &name, const size_t &defaultValue) {
QVariant cfgVariable = qsSettings->value(name, defaultValue);
bool ok = false;
qulonglong value = cfgVariable.toULongLong(ok);
if (!ok || value > std::numeric_limits<size_t>::max()) {
qCritical() << "Configuration variable" << name << "is of invalid format. Set to default value of" << defaultValue << ".";

Experimentation with typesafe indices for https://plus.google.com/u/0/103771295878903986513/posts/CiwQXgwHbJ1 Basically the gist of what I wanted from a strongly typedef'd size_t. This example only implements the operators I needed and already took quite a bit of code that might (will ;) ) contain bugs and unexpected behavior. For my application…
#include <vector>
#include <cstddef>
template<typename Tag>
class TypesafeIndex
{
public:
inline TypesafeIndex() : m_i() {};
inline explicit TypesafeIndex(const size_t a_value) : m_i(a_value) {};
