As promised before, I’m starting the new course and I have new stuff to post :). One of my subjects is Integrated Circuits Design. The first day, as usual, teacher gave us a presentation about the subject and I liked it. Why? Because we will have 6 conferences along the course, and they do sound interesting! And you all know I love conferences and I always let you know what the speaker tell us so, here I advance you which are gonna be my posts during this semester (among others, of course!):

1. From micro to nano systems - by Dra. E. Valderrama
2. Computing architectures in reconfigurable systems - by B. Martínez
3. Sensors and actuators applied to personal autonomy for handiccaped persons and the old age - by Dr. V. Soler
4. Micro and nanotechnology for spacial applications - by Dr. C. Ferrer
5. Multi-robot systems applied to biomedicine - by Dr. L. Ribas
6. The microtechnology’s market - by Dr. J. Agulló

Notice that each speaker is highly qualified: most of them are doctors!

I have to attend 3 conferences at least in order to pass the course so, I’ll post, at minimum, 3 conferences. However, I’ll try to assist as many as I can. But don’t blame me if I don’t post a conference which you like, conferences are on Friday, it’s a difficult day;)!

Ok, it’s a bit nazi, but I think I’ve laughed so loud that anybody within 5miles has listened to me. I’m really sorry but I couldn’t contain myself. You’ll agree with me, I’m totally positive! Here’s the image (click to enlarge).

I’m posting too many humor posts lately, I hope it will end once I’m back studying at University. Either way, this is one of the best videos I’ve ever seen about programming! I have an ace up one’s sleeve, keep coming ;)!

I’m sure a lot of developers will enjoy this video

It was dark, raining cats and dogs. It was the time. It was now or never… He has no option. He looked back and stared, easy, at Redmon. He couldn’t stifle a tear, it was so hard after so many years… But he had already taken the decision. He can’t feel anything but sorry for his people. As a matter of fact, he was sure they were going to find another one, better than him, stronger, faster, more reliable. Nevertheless, even though he knew that, it still hurt. He didn’t want to leave… But he had to, he was no longer doing any good there. He had to leave, and the sooner, the better. He crossed the street and stopped by at the bar where he had always met with his friends, MAC and so on. He sighed, and went ahead. He started remembering while walking…

Once, he was the only option.
Once, all the people wanted him.
Once, he was, by far, the best.
Once…

A car tooted the horn and almost hit Windows Vista. He cursed all the insane drivers, but it didn’t matter. It wasn’t about a car, a driver… He was tired, he couldn’t stand this any more. It was being too much for him. At the beginning, nobody could have imagined it was going to go so far, nobody could have imagined that GNU was going to be a threat to Windows, much less in Vista. But this is technology and what’s good today, is probably bad tomorrow. He arrived at his destination. He started formatting himself (he couldn’t be discovered. It was the first and the most important rule: his code must remain secret, always. No exceptions). When he had almost being converted to NULL positions, he managed to finish with his pain, finally. Nobody will never be able to programme him again, he didn’t worth it. Free software had win the battle and now, another era was coming and there was no place for him.

Goodbye, and good luck, Microsoft

At the moment of choosing Windows or Linux everyone will have his own preferences … But this spot, released in 2003 by IBM, it’s awesome. I liked it and I wanted to share it with you. Judge yourself.

What is DDDAS? It is a new paradigm, where computer programs act in a more intelligent way. Their outputs depend on their inputs, which are updated values in the real world, used for optimizing the minimum damage/etc of important problems such as natural catastrophes. The other day, Dra. Frederica Darema came to UAB to give us a conference about DDDAS. I attended it. We could say that DDDAS is a new direction for applications/simulations and measurement methodology.

Until now, programs are mostly unidirectional. It means that we have a direction between theory and simulation, and ANOTHER ONE, between simulation and theory. In the same way, we’ve got a third element: measurements.

Theory -> Simulations | Simulation -> Theory | Measurements -> Simulation | Simulation -> Measurements | Theory -> Measurements | Measurements -> Theory

This is too static and serialized. Too slow! This is enough for normal programs and situations, but what happens when LIFES are up to a few minutes? We have to speed it up as much as we can. So, this is DDDAS: Data is not unidirectional but bidirectional. Or in other words, we haven’t got a strong direction, we’ve got a data stream going and coming. A stream data between execution processes.

I’ve been studying Computers Structure this course, and the last laboratory project was to create a soccer scoreboard (CODE at the end).

We have to show “Hola mundo”, using an LCD, all the time, and when a interruption occurs, we have to show “GoooL” 12 times, and then, show the current scores of each team (host & guest) for a second. An interruption means that one team has scored (depending on which button has been pushed, it’s either one team or the other). We have used CODEWarrior program to compile our assembler code, the motherboard is HCS12 (16-bits CPU, freescale), and the LCD is HD44780U.

Here a video of almost the last version:

I didn’t want to post anything more today until next week… But this is almost compulsory! My fucking god, sometimes there are websites that make me freak out… How the hell can a so popular website have such a vulnerability?

Talking about SQL Injection is in my blog list now.

What do you think I could do with the following information I’ve just received after sending a VERY SIMPLE attack to the website?

Failed on select title.text, mistake.title, mistake.timecode, media, mistaketext.text, if((mistake.modified3) < (now() - interval 1 year),’yes’,'no’) as yearold, date(mistake.modified3) as date, mistake.type from title, mistake, mistaketext where mistake.id = ” or 1=1′ and mistaketext.id = mistake.id and mistake.title = title.id

Yes… You are right. EVERYTHING.

Reminding that all information (including admin password and so on) is stored in the website DataBase…

Have fun…

First of all, we should know what SSH is:

Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two computers. Encryption provides confidentiality and integrity of data over an insecure network, such as the Internet. SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if necessary.

This means that you may need to access from wherever to either your home-computer or work-computer. Using SSH protocol and Linux on the OS side, it’s easy. Anybody can use this protocol and he will be able to login remotely and execute commands (VNC is a alternative: it uses graphical mode, but data is not encrypted). I wanted to access my home-computer (reasons are besides the point), so I had to install a SSH server on my computer. As it gave me headache due to a silly thing, I’ll show you how you must do that.
