Using Facebook Graph API to keep an eye on friends activity

Posted on by
1

Life is really moving in the fast lane for me, and Im pretty sure for most of you readers too. I login to social-networking platforms after weeks and I cant recognize most of these faces (even though they are my friends). Its proven that Humans tend to recognize people by face more quickly then names and email addresses so whenever someone puts on a new face (uploads a new profile-picture), I have hard time getting to know them.

Well, I thought today, I have been developing in facebook application for so long now – Why not put online a few hours to fetch Facebook Friends data via API and keeping track of who did what? (status updates) and who changed his/her profile picture? So last night I was up, as usual, and I put together a small script in PHP that fetches my friends’s list, processes newcomers, checks for updates (pictures and statuses) and posts them into a database. Now I can track who updated his profile picture and what was their previous profile photo. Also, I can invest in another 1 hr to create high-level-summary everyday for ME :)

Do you do something of this sort? I’d love to hear your story

Update (25-Aug-2010): Rus Foster from ThrustVPS.com is a blackmailer and a person with low self-esteem. He actually blackmailed me to hand him over certain domain names which he thinks believes is breaching the AUP. My accounts, VPS and the $60 of affiliate commission was terminated. I will advise everyone to KEEP AWAY from Rus Foster and ThrustVPS.com (click here to read the full review)

Not getting a package on Ubuntu?

Posted on by

If you are not getting a package on Ubunu using apt-get then chances are that it has not been updated in the /etc/apt/sources.list file

For example, the following should be there in the sources.list file if you are running Ubuntu 10.04 LTS (codename lucid)

## main & restricted repositories
deb http://us.archive.ubuntu.com/ubuntu/ lucid main restricted
deb-src http://us.archive.ubuntu.com/ubuntu/ lucid main restricted

deb http://security.ubuntu.com/ubuntu lucid-updates main restricted
deb-src http://security.ubuntu.com/ubuntu lucid-updates main restricted

deb http://security.ubuntu.com/ubuntu lucid-security main restricted
deb-src http://security.ubuntu.com/ubuntu lucid-security main restricted

## universe repositories - uncomment to enable
deb http://us.archive.ubuntu.com/ubuntu/ lucid universe
deb-src http://us.archive.ubuntu.com/ubuntu/ lucid universe

deb http://us.archive.ubuntu.com/ubuntu/ lucid-updates universe

Update (29-Aug-2010): Please check the latest benchmark results from their XEON node, pretty awesome for a 1024MB VPS.

Unix Benchmark results from HazeNet VPS using unixbench v 5.1.2 (please note that these are Quad-Core benchmark and not the new i7s and XEON that they are offering)

Specs: 1GB / 50GB OpenVZ

How to install byte-unixBench on Ubuntu

Posted on by

From UnixBench project homepage:

UnixBench is the original BYTE UNIX benchmark suite, updated and revised by many people over the years.

The purpose of UnixBench is to provide a basic indicator of the performance of a Unix-like system; hence, multiple tests are used to test various aspects of the system’s performance. These test results are then compared to the scores from a baseline system to produce an index value, which is generally easier to handle than the raw scores. The entire set of index values is then combined to make an overall index for the system.

Some very simple graphics tests are included to measure the 2D and 3D graphics performance of the system.

Multi-CPU systems are handled. If your system has multiple CPUs, the default behaviour is to run the selected tests twice — once with one copy of each test program running at a time, and once with N copies, where N is the number of CPUs. This is designed to allow you to assess:

* the performance of your system when running a single task
* the performance of your system when running multiple tasks
* the gain from your system’s implementation of parallel processing

Do be aware that this is a system benchmark, not a CPU, RAM or disk benchmark. The results will depend not only on your hardware, but on your operating system, libraries, and even compiler.

First install required libraries for compilation :

apt-get install libx11-dev libgl1-mesa-dev libxext-dev perl  perl-modules make

Then get the unixbench and run it :

wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz
tar xvf unixbench-5.1.2.tar.gz
cd unixbench-5.1.2
./Run

Installing Lighttpd, PHP and MySQL on Ubuntu

Posted on by
6

If you are not getting a package on Ubuntu, please check to see if your /etc/apt/sources.list file is updated. This is common with most VPS providers

On VPS, especially with challenging small memory limit (e.g. 64MB or 128MB) lighttpd is the best option instead of Apache. In this article I will show you how to do that. On a fresh box (which has no apache installed) type this to get lighttpd webserver installed

apt-get install lighttpd

Now install PHP5 CGI package and PHP5 command line package

apt-get install php5-cgi php5-cli

Edit the following file

nano /etc/php5/cgi/php.ini

and uncomment this line

cgi.fix_pathinfo = 1

Now enable fastcgi module

lighty-enable-mod fastcgi

Restart Lighttpd

/etc/init.d/lighttpd restart

You get the welcome page

Lets install MySQL 5.1 server and client

apt-get install mysql-server mysql-client

and optionally phpMyAdmin

apt-get install phpmyadmin

Now create a test page to see if phpinfo is all Ok

nano /var/www/info.php

Type in the following

<?php
phpinfo();
