I am a highly motivated, results-driven IT professional with 10 years experience, a systems engineer who enjoys working on large-scale systems and challenging problems. I have experience with large number of servers (10.000+) connected via WAN and LAN, which makes it possible for cloud providers to deliver reliable services to customers

My current role is: systems engineer of the team which runs the websites.

On the top of usual systems engineering tasks, I like to develop softwares, my main language is Ruby (and I use Ruby on Rails of course :) ) but I can read and understand (and fix) Perl and Python, however it is not my favorite. I started to learn Erlang recently, which helps me understand the challenges what software developers face with distributed systems.

comment workaround for cross domain on ec2 clouds
If you want the user to use i1 and i2 just construct the html and use URLs from both of them.

comment mysql is not using multiple cpus
Since you are using Myisam table type, InnoDB's concurrency has no effect to your mysql server. I am not aware of any configuration or setting which makes myisam scale for multicore systems.

comment How can I detect Slowloris?
Yes, after the attack is over you are going to see many 400 errors in the log files. As it is described on the slowloris website.

comment How can I detect Slowloris?
Well I though Apache fixed this long time ago, but it seems this is not the case. I am using nginx as the frontend for apache so this is how i mitigated this stupid bug.

comment How can I detect Slowloris?
My understanding is that by time they can use all your resources with low amount of connections. And few IPs are enough. Better if you test it than make an assumption.

comment Site loads very slow if I use IP and works normal when I use Domain Name, Why?
Sure, no problem. So when you hit a website with you browser it sends some data to the server called HTTP request header. You can check this URL: en.wikipedia.org/wiki/List_of_HTTP_header_fields So one of these is the "Host" field which tells to the webserver which virtual host to serve. Imagine you have www.yourdomain.com and www.alsoyours.com on your server and both points to the same IP. So the web server must know which one to serve and the decision is based on that field. Hope it helps.
