Changing Ubuntu Server Timezone by command line

When you install Ubuntu server distribution, you would got problem when choosing the time zone, especially for Indonesian time zone. Because I had install ubuntu server several times, but you can only choose US time.

So, the easiest way is trying to change the time zone after the installation process is completed. Here is that simple command


koro@kecapi:/etc$ sudo dpkg-reconfigure tzdata
[sudo] password for koro:

Current default timezone: 'Asia/Jakarta'
Local time is now: Wed Apr 14 10:46:47 WIT 2010.
Universal Time is now: Wed Apr 14 03:46:47 UTC 2010.

koro@kecapi:/etc$ date
Wed Apr 14 10:52:47 WIT 2010

Do not forget to choose your time area according to your geographic region.

Virtual Machine Software

The words “virtual” or “virtualization” even “emulator” is seen more popular this decade. Right now I’m more focusing on the animal because it’s part of my hobby and job.

I just want to share here, even you may be already know and maintaining the systems. But I think the others want to know accord to my humble opinion. Below is the list of Virtual Machine Software or Software Emulator

  1. XEN
  2. OpenVZ
  3. KVM
  4. Virtuozzo

You can know more about that software when you try to google them. There are many other software that can be used as software emulator or virtual machine. If I have more time, I will try to write about what the advantage and disadvantage using that software

Windows 7 alias MinWin: A Windows Vista Replacement

Talking about the operating system batlles such as *NIX Family, DOS, Windows will never end. Open source and GPL enthusiasm realize that Windows Family operating system is their competitor. But Microsoft has prepared its newest prototype operating system with name: Windows 7 or MinWin in their internal projects.

Why MinWin? Why Windows 7? We know that almost all Microsoft Windows operating system use large storage, more RAM, better hardware, than the old one. But Microsoft realize them and want to make a next-generation operating system killer. Eric Traut of Microsoft present MinWin at ACM conference at University of Illinois, US, into a virtual machine with just 40 MB and when try to boot the OS, voila…. It was just use about 33 MB. For comparative, Vista User will need about 4 GB disk space and 5,000 files. But this MinWin is using 100 files and 25 MB disk space.

This future OS is predicted to be released on 2010.
