From the desk of Samy,
I’ve come across this video… I think it’s very funny. What happens when you throw boiling water into the air when it’s -45 degrees, when it’s sooo cold…???

DDDAS - Dynamic Data Driven Application Systems
From the desk of Samy,
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.

HCS12, CODEWarrior and HD44780U
From the desk of Samy,
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:

3000 visitors!
From the desk of Samy,
My blog is up to 3.000 visitors! I really thought that there was no way to achieve such amount of people visiting my blog 
But get ready… I’ll reach the 10.000 visitors barrier…
