Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns                     on recent CPU
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 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 4X memory

A lot of these are outright stolen from Edward O'Campo-Gooding's list of questions. I really like his list.

I'm having some trouble paring this down to a manageable list of questions -- I realistically want to know all of these things before starting to work at a company, but it's a lot to ask all at once. My current game plan is to pick 6 before an interview and ask those.

I'd love comments and suggestions about any of these.

I've found questions like "do you have smart people? Can I learn a lot at your company?" to be basically totally useless -- everybody will say "yeah, definitely!" and it's hard to learn anything from them. So I'm trying to make all of these questions pretty concrete -- if a team doesn't have an issue tracker, they don't have an issue tracker.

I'm also mostly not asking about principles, but the way things are -- not "do you think code review is important?", but "Does all code get reviewed?".

Hello,

After looking for a simple Class system in JavaScript, and looking at all the horrible libraries, forced upon terrible syntax, cluttered objects and prototypes... I'd like to introduce a simple alternative.

This is a very bare-bones, and yet one of the more powerful class systems in JavaScript. Built on-top of Object.create and prototype inheritance using the methods that everyone suggests is the best way to do classes in JavaScript ported over to a nicer syntax.

It doesn't clutter the properties or the prototype aside from a single method which is extends, and even this method is sugar and not required!

Check out zoo.js for an in-depth example of how to use Class. No matter how deep down the rabbit hole you go, it should keep references so you can do instanceof checks on children of a parent of a grand-parent and so forth.
