Check Out these projects, papers and blog posts if you're working on Geo redundant Datacenters or even if you only need to have your software hosted there. It's good to know what you're in for.

  Collected these for a colleague, these have been super useful over 
  the past 15+ years and and will most likely help and/or entertain you. 
  May be extended in the future.

It "types" the contents of the clipboard.

Why can't you just paste the contents you ask? Sometimes pasting just doesn't work.

• One example is in system password fields on OSX.
• Sometimes you're working in a VM and the clipboard isn't shared.
• Other times you're working via Remote Desktop and again, the clipboard doesn't work in password boxes such as the system login prompts.
• Connected via RDP and clipboard sharing is disabled and so is mounting of local drives. If the system doesn't have internet access there's no easy way to get things like payloads or Powershell scripts onto it... until now.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
