To implement Ratchet.io's Person Tracking feature, we have a MySQL table like this:

create table person (
  id int unsigned not null,
  project_id int unsigned not null
  environment varchar(255) not null,
  person_id varchar(40) not null,
  username varchar(255),
  email varchar(255),

If you want to access the source code of a Chrome extension, you need to get the .crx file. This bookmarklet downloads the .crx file for the Chrome extension you're viewing. You'll be prompted to install it; before dismissing the dialog, check in your Downloads directory. Then just unzip the .crx (it's a zip file).

javascript:window.open('https://clients2.google.com/service/update2/crx?response=redirect&x=id%3D' + /webstore\/detail\/[^\/]+\/([^\/]+)/.exec(window.location.href)[1] + '%26uc')

slow

This bash script offers quick shortcuts to simulate slower network connections. It is useful when you need to simulate a wireless network on a Linux network server, especially when you are using a virtual machine guest on your local machine or in the cloud.

slow 3G                   # Slow network on default eth0 down to 3G wireless speeds
slow reset                # Reset connection for default eth0 to normal
slow vsat --latency=500ms # Simulate satellite internet  with a high latency
slow dsl -b 1mbps         # Simulate DSL with a slower speed than the default

slow modem-56k -d eth0 # Simulate a 56k modem on the eth1 device. eth0 is unchanged.

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
