Accessing a VirtualBox Machine with NAT

by wnoronha

The default way a VirtualBox machine connects to the network is using NAT. Since it’s connected to a private network, you can connect to the outside world but other machines cannot contact you (this holds true even for the host machine). NAT is the easiest and most lightweight way of connecting your virtual machine to the network. VirtualBox also supports others ways of connecting to the network such as a bridge adaptor.

My current setup: I have one virtual machine running Ubuntu 9.04 where I have all my development tools and languages installed (ruby, php, python etc). I run VirtualBox 3.0.8 on my MacOS laptop. This way I can be as close to the server environment as possible while building my applications. I run Apache, Passenger, PHP, MySQL on the guest machine and just forward 22 (ssh), 80 (http) and 3306 (mysql) to MacOS this way I can use apps like MySQL workbench to play with my database or Textmate to code.

Linux kernel upgrade? Try Ksplice

by wnoronha

Ksplice allows system administrators to apply security patches to the Linux kernel without having to reboot. Ksplice takes as input a source code change in unified diff format and the kernel source code to be patched, and it applies the patch to the corresponding running kernel. The running kernel does not need to have been prepared in advance in any way.

Download the latest Ruby Gems from here

Creating magic with ALT-F2View

by wnoronha

I am pretty sure you know what the ALT-F2 does; viz. opening a "Run Command" dialog. What you did not know is that you can do a lot more than just enter program names and click on "Run".

Some interesting things you can do with it.
