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

A Common .ruby-version File For Ruby Projects

Background

I've been using this technique in most of my Ruby projects lately where Ruby versions are required:

• Create .rbenv-version containing the target Ruby using a definition name defined in ruby-build (example below). These strings are a proper subset of RVM Ruby string names so far...
• Create .rvmrc (with rvm --create --rvmrc "1.9.3@myapp") and edit the environment_id= line to fetch the Ruby version from .rbenv-version (example below).

Today I learned about another Ruby manager, rbfu, where the author is using a similar technique with .rbfu-version.

# capybara step definition for a quick and dirty date select
# For example:
# When I select "May 7, 2010" as the post "published_on" date

When /^I select "([^"]*)" as the (.+) "([^"]*)" date$/ do |date, model, selector|
  date = Date.parse(date)
  select(date.year.to_s, :from => "#{model}[#{selector}(1i)]")
  select(date.strftime("%B"), :from => "#{model}[#{selector}(2i)]")
  select(date.day.to_s, :from => "#{model}[#{selector}(3i)]")
end
