58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

Configure mongo for replication

• Make sure you have sufficient disk space to hold the oplog ( can be several GB )
• Edit /etc/mongodb.conf to add replSet = rs0
• Restart mongodb
• In the mongo REPL execute rs.initiate() ( this can take some time; log shows activity )
• Try executing a query, your REPL prompt should now be rs0:PRIMARY>

Secure private web server with NodeJS

This article will explain how to set up a secure web server with NodeJS which only accepts connection from users with SSL certificates that you have signed. This is an efficient way to ensure that no other people are able to access the web server, without building a login system which will be significantly weaker.

I will not explain how to create a certificate authority (CA), create certificates or sign them. If you need to read up on this, have a look at this excelent article on how to do it with OpenSSL (Mac and Linux): https://help.ubuntu.com/community/OpenSSL#Practical_OpenSSL_Usage It is also possible to do this on a Mac with the keychain application, and I assume it is possible on a Windows machine aswell.

This architecture will allow you to have one web server communicating with an array of trusted clients, the web server itself can be on the public internet, that will not decrease the level of security, but it will only ser

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
