It’s confronting, no?

Just a bunch of people with their according passwords in plaintext πŸ™‚

It’s the result of a project of mine in 2007 from school. Apparently everyone creating an account on the website had full trust in me (even people I’ve never heard of)… Poor people πŸ˜›

Never trust something you don’t entirely know πŸ™‚

“Secrets” will eventually spread: linkedin,, … ING?

If you follow me on twitter, you might have read my tweet about my leaked linkedin password.
Yep, it’s out there!
Go and find it! I still haven’t changed it 😎
(Challenge: the first one who can actually post something on my facebook wins a crate of beer!)

P.S.: A good trick to know if your password is stored in plaintext on a website: if you’re able to “recover” password when you’ve “forgotten” it: it’s plaintext…
When you have to reset it completely, it’s probably hashed πŸ˜‰


Kot te huur in Gent!
Spiegelhofstraat 56!

270€ + 50€ aan elentriek/water/internet enzo
+5€ als je een ijskast op uw kamer hebt…

Tis weg =)

So, what are we studying these days

  • Advanced computer architecture
    Pretty cool, about how a cpu is build @ ISA level.
  • Design of distributed systems
    Also an interesting course! A bit to much java tough…
  • Multimedia networks
    Nice, untill the subject changes towards “optimization techniques”… 😦
  • Something called discrete mathematics
    Not much to say about this, just some mathematics πŸ™‚


  • Maybe information theory as well, we’ll see πŸ™‚

So I know what to do the following days…
So… Ciao!

(Check soup! :P)

Let’s talk a bit about ISSISP, the reason why I was in Ghent the entire week…

It’s a summer school, organised by Prof. Bjorn De Schutter from the University of Ghent.
ISSISP stands for “International Summer School on Information Security and Protection”, it’s now organised for the 2nd time and is supported by IEEE, ACM, Irdeto and some others…

We have all kind of cool guest speakers:
βœ“ Christian Collberg (University of Arizona, USA)
βœ“ Jack Davidson (University of Virginia, USA)
βœ“ Roberto Giacobazzi (UniversitΓ  di Verona, Italy)
βœ“ Yuan Xiang Gu (Irdeto, Canada)
βœ“ Bjorn De Sutter (Ghent University, Belgium)

And they all talked about different techniques on protection software from third-party users. Like for code that checks licensing information and how hackers try to get around it…

Code obfuscation, watermarking, virtualisation, tamperproofing, … All pretty cool techniques for hiding information of your code and making sure nobody else could use it πŸ™‚

It where nice courses, it where (the one more than the other) fascinating speakers, cool people around, very good organisation, …

Actually, I don’t have any negative points! =)

It was fun and I learned really a lot!

Way to go!

UGent: 5 vakken, 5 examens.

  1. Ontwerp van gedistribueerde software: p2p, java rmi, corba, enterprise applicatoins, cluster & grid software, …
  2. Geavanceerde computerarchitectuur: cache’s, multithreading, out of order logic, …
  3. Design of Multimedia Applications: jpeg, jpeg2000, mpeg, h.264, …
  4. Software Architecture: het antwoord op de vraag “hoe organiseer ik mijn software”
  5. Capita selecta mathematicae: wie weet da jong… ^^Β  verzamelingen, groepen, vectorruimten, vectoranalyse, holomorfe functies, en gelukkig ook nog differentiaalvergelijkingen

4 van deze vakken vallen mee/zijn intressant/is zelfs leuk :mrgreen:


Did you know one of the constraints of having a CPU ticking at higher clockspeeds is a problem caused by its interconnects?
Its limited because an electronic signal just cannot move across a cable fast enough, when cables are placed to close to each other they introduce noise, and the signal degrades over distance. (url)

So IBM, Intel and other research groups are looking for a solution! And apparently they found it in the light! Literally! 😎

The use of optical interconnects is the future. Nowadays it use lies mostly in networking appliances. But research groups are trying to miniaturize the needed lasers, and detectors (url).
The need for these optical connections to replace the classic copper lines on your motherboard, and even inside a cpu.

So the future enlightens our computer, bandwidths up to 100 times higher, and latencies 10 times lower as current technologies allow πŸ™‚
It dissipates almost no heat, has no crosstalk, multiple beams can co-exist,

Another nice thingy: components are not forced to be placed next to each other any more: one of the reasons RAM on a motherboard is so close to the CPU is the latency, now you can place your banks like 10 meters out of each other and still have faster responses then copper can provide 😈

This post is just for your information, details can be wrong, it’s just an insight πŸ™‚ more information on this topic on on ieee, physorg and many many many others πŸ™‚
