To claim this, I am signing this object:

	How to undo published commits

	git reset (sha)
	git checkout (all files that need to be undone)
	git commit -am (message for reset)
	git push -f origin (branch name)

	/* Returns the next back off interval for POST request */
	func nextBackOffTime() time.Duration {
	collisionNumber := float64(networkStatus.failCount)
	backoffTime := time.Duration((math.Pow(2, collisionNumber) - 1) / 2)
	return backoffTime
	}

	// Download a playlist from index, and skip errors
	sudo youtube-dl -i --playlist-start 0 [link]
	-i = continue on error (skip song)
	--playlist-start [index] = start downloading at a index

	// Download a mp3 form youtube
	sudo youtube-dl --extract-audio --audio-format mp3 -o "%(title)s.%(ext)s" [link]

	// Download mp3 from Soundcloud ignore errors
	sudo youtube-dl -i -o "%(title)s.%(ext)s" [link]

	Latency Comparison Numbers

	L1 cache reference 0.5 ns
	Branch mispredict 5 ns
	L2 cache reference 7 ns 14x L1 cache
	Mutex lock/unlock 25 ns
	Main memory reference 100 ns 20x L2 cache, 200x L1 cache
	Compress 1K bytes with Zippy 3,000 ns 3 us
	Send 1K bytes over 1 Gbps network 10,000 ns 10 us
	Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD

	formatAllotmentValue = (value) ->
	_value = parseFloat(value)
	if parseFloat((_value%(Math.floor(_value))).toFixed(1)) >= 0.5
	return Math.floor(_value) + 0.5
