Pakistan Tehreek-e-Insaf (PTI) SMS Alert service

Submitted by Derick Ng on 26 July 2011 - 6:13am

Pakistan Tehreek-e-Insaf, one of the political parties of Pakistan has introduced a one of its kind service in Pakistan. They will be sending SMS and has asked everyone to join for free.

The thing I like about Pakistan Tehreek-e-Insaf (PTI) is that its moving away from the bullsh*t drama happening in the country and probably thats the reason its becoming so popular in general public especially youth as well.
To subscribe to these SMS notifications, just send your name + city via SMS to 80022 (using any cellular network in Pakistan)

Enable ping response for Windows Server

Submitted by Derick Ng on 16 May 2011 - 11:15pm

I recently got two windows VPS for testing and stuff. The issue I faced was that even though they were Windows 2008 VPS, I still could not ping it. Came to know later that its a security feature and hence all pings are disabled.

You just need to enable it by running the following command on command prompt
netsh firewall set icmpsetting 8
If you wish to disable it, later, you may run this to do so

Overcommitting with KVM

Submitted by Derick Ng on 10 May 2011 - 3:54pm

Someone pointed out a shocking fact in LET that KVM, the new popular virtualization type, can be over-committed even more then the infamous OpenVZ
The KVM hypervisor supports overcommitting CPUs and overcommitting memory. Overcommitting is allocating more virtualized CPUs or memory than there are physical resources on the system. With CPU overcommit, under-utilized virtualized servers or desktops can run on fewer servers which saves power and money.

vzfree utility to check memory usage in OpenVZ VPS

Submitted by Derick Ng on 23 April 2011 - 4:00am

From the official blog post
Gee. It has been a while since I’ve last written here, and it will be a while again for my next post as I will be on holidays from next Monday (visiting families in Hong Kong and Taiwan). Let me share one small utility program that I wrote quite a while ago.
We all know that the Linux command free(1) is pretty useless inside an OpenVZ VE, even those with meminfo virtualised. So I basically wrote this little util to grab the data from the dreadful user_beancounters and format them into something useful. It’s written in C and only depends on libc so it’s pretty light weight. It also does a little bit of analysis instead of just dumping the data, which I will explain later on.
To install vzfree, do this

Dropbox is insecure? A critical review

Submitted by Derick Ng on 20 April 2011 - 9:27pm

I am a die hard Dropbox fan, although the files that I share are neither too sensitive nor do I pay attention to the TOS (Terms of Service) of dropbox but this article is a nice read for anyone who is considering syncing sensitive files (private file that is).
