Everything below is outdated :) I really don't have the time to update this. Most important update is that I am a part of the LearnWorlds team now.

Hello, I'm Nikos, I am a programmer and I like everything "Computer Science".

I am happily employed at Cs Circles, without a doubt the best programming company In Cyprus. I am programming 12 hours per day, eirther on my projects on Cs Circles or on pet projects at home. I love everything OpenSource, PHP, Linux and although I am a developer I really like managing Linux machines.

I have designed and implemented several types of software. I believe in keeping things simple, always have the big picture in mind and never overreach.

Finally I believe that a computer scientist is not just someone that can design good software, but can also implement it. I believe that a mediocre idea with an excelent implementation is far more valuable than a superb idea with poor implementation. In a sentence, "Ideas are cheap, implementation is everything"

I can work with almost any language, but I am fluent at Php and Java. I love frameworks like Symfony, Codeigniter and Laravel, and I even created my own CMS from scratch based on Codeigniter ideas.

That process has given me a unique prospective on designing software architecture which is very a different process than just programming.

I also like everything related with IT Security. I have much experience writting custom exploits and mass scanners for specific vulnerabilities. I like testing the limits of application and find ways to bypass limitation.

Electrical and Computer Engineering

Volos Greece

The Electrical and Computer Engineering department in Volos (Computer and Communications Engineering then), one of the top in the Country was challenging and fun. Big demanding projects and lots of labs, gave me the maximum I ever dreamed of receiving from my university years.

The department was relatively new, and what was really good about it was that most Professors came fresh out from the IT industry. While specialized in software I acquired a deep understanding of Hardware, Math and Electrical Engineering.

Quality magic lectures from the best teachers, attention to every detail and a deep dive into all subjects is what makes this school perfect for future engineers.

The gods were kind and the rewarded me with much fun. One fellow white hat hacker, Andrew Tierney, was blessed with the… read more

The ForthPwn – Or how to break the forth.gr captha for fun (and not even a remote chance of profit :) )

Intro The primary function of a captcha is to prevent an automated software simulating human activities like registering forms, view important information etc. They are used as a precaution to prevent automated software of copying content, or protecting a system from automated requests. They work pretty well, but implementation errors are very common. Captchas is… read more

primeTeller – The primetel password generator.

Security in Cyprus is bad. That is not a surprise. Primetel uses insecure default passwords in their WIFI routers. A WPA password can be cracked in 4-5 seconds with a simple laptop. If you are interested in the details see below. I used Primetel on the my previous apartment. The password was on the form… read more
