thatwist / CapsLockCtrlEscape.ahk

Created July 30, 2019 10:46 — forked from sedm0784/CapsLockCtrlEscape.ahk

AutoHotkey script to map Caps Lock to Escape when it's pressed on its own and Ctrl when used in combination with another key, à la Steve Losh. Adapted from one that does something similar with the Ctrl Key on the Vim Tips Wiki (http://vim.wikia.com/wiki/Map_caps_lock_to_escape_in_Windows?oldid=32281). (Plus contribs from @randy909 & @mmikeww.)

	g_LastCtrlKeyDownTime := 0
	g_AbortSendEsc := false
	g_ControlRepeatDetected := false

	*CapsLock::
	if (g_ControlRepeatDetected)
	{
	return
	}

Last active March 30, 2018 12:12

Checks Wirth–Weber precedence relationship. This is an old piece of code I wrote in university - this is scary but it works.

thatwist / phone_number_to_words.scala

Created December 6, 2017 18:47

Parses a phone number and finds all possible words based on numpad-to-letter mapping and dictionary

	trait SolutionDef { self: DictionaryDef with DebugDef =>
	/*
	* based on the example included:
	* 866-5548 -> tool-kit
	* the assumption is made that '-' symbol position doesn't matter
	* and it's not a word divider
	* e.g. any of those groups of numbers can make up a final sequence of words:
	* 86 65548, 86665 548, 86 655 48, etc.
	*
	* here is no phone number format specified as every coutry has its own

thatwist / prime_product_palindrome.scala

Created December 6, 2017 18:41

	import scala.annotation.tailrec
	import scala.collection.parallel.mutable

	object Solution extends App {

	def isPalindrome(n: Int): Boolean = {
	var num = n
	//reversing number
	var rev = 0
	var rmd = 0

Trying to project map to tuples in typesafe way (think I need shapeless here :-P)


	object Projections {

	object MapUtils {

	implicit class MapWithGetAsInstanceOf[A](map: Map[A, Any]) {
	/** get by key and cast to T, exception if cannot cast */

	import Romans._

	assert(resolveRoman(3999) == "MMMCMXCIX")
