	netsh wlan start hostednetwork

fairlight1337 / ls-branches

Last active August 8, 2016 07:24

A script I put into my $PATH and use for quickly listing the currently selected branches of all subdirectories (rather than going through them one by one)

	#!/bin/bash

	MASTER="master"

	for item in $(ls -1); do
	if [ -d $item ]; then
	cd $item

	if [ -d .git ]; then
	branch=`git rev-parse --abbrev-ref HEAD`

fairlight1337 / Synchronized.cpp

Last active August 14, 2019 16:34

Simple synchronization class for allowing the same thread to enter a function over and over again, but shutting out others while it is in use

	#include <iostream>
	#include <condition_variable>
	#include <mutex>
	#include <thread>
	#include <string>


	class Synchronizer {
	private:
	std::condition_variable m_cvCondition;

fairlight1337 / Conditional.cpp

Trying out `conditional_variable` in threads (C++)

	#include <iostream>
	#include <condition_variable>
	#include <mutex>
	#include <thread>
	#include <string>
	#include <chrono>
	#include <vector>


	int nWorkersActive;

fairlight1337 / catch_segv.cpp

Last active October 9, 2024 15:01

Catching SIGSEGV (Segmentation Faults) in C

	// This code installs a custom signal handler for the SIGSEGV signal
	// (segmentation fault) and then purposefully creates a segmentation
	// fault. The custom handler `handler` is then entered, which now
	// increases the instruction pointer by 1, skipping the current byte
	// of the faulty instruction. This is done for as long as the faulty
	// instruction is still active; in the below case, that's 2 bytes.

	// Note: This is for 64 bit systems. If you prefer 32 bit, change
	// `REG_RIP` to `REG_EIP`. I didn't bother putting an appropriate
	// `#ifdef` here.

fairlight1337 / cpp-py

Last active August 14, 2019 16:35

Hello World program compilable (/runnable) as both .py and .c(pp). Makes use of the #define preprocessor directive of C/C++ to make Python code invisible to the C compiler while using multiline comments from Python (""") to make C(++)-code invisible to the Python interpreter. Both programs just output "Hello World from both!", while each program…

	#// This comment is invisible to both, Python and C(++).

	#/*
	# This multiline comment is also invisible to both.
	#*/

	#include <stdio.h>

	#define pass void printstring(char* x) { printf("%s", x); printf("\n"); }
	pass
