Well, the portuguese navigators did have a lot of trouble crossing it. This was due to the fact that they mostly always sailed with the coast in sight, but when they reached the equator, there was just no winds or currents to keep pushing t

But remember also that northern hemisphere navigators like the Portuguese also had to align their maps in a different direction as they crossed the equator and lost their main reference star on their way around Africa. They soon discovered

To be quite frank I wonder what is better for the country: staying there, working your ass off and getting just enough to survive, or being outside, opening your horizons, maybe being exposed to new ways of thinking, technologies or ideas,

I'm one of those about to graduate students from a technical university in Lisbon, and for me, there is no doubt anymore, I'll start to work outside of Portugal. When you look at it from one side, South European countries have everything: t

Once I thought of something like that too, but in the environment of a park with speakers and wifi (yeah, far fetched, I know). People could go to a website available on the wireless network with their smartphones and pick a track to play (

WOW! I had exactly this idea at a Hackaton festival called Codebits in Portugal in November last year and presented it[1] to the audience but didn't receive that much excitement from them about my implementation done in 12 hours using JS an

If the salt is the same for all the users you can have it on the source code that hashes the passwords. Not always being SQL injected means having the back-end code leaked.

That's why I have friends lists. Just some weeks ago some girl I didn't know that happened to be the designated driver of the group of friends I was with on the new years eve sent me a friend request on facebook. I don't want to be rude and

The biggest illusion of progress bars is when they don't accurately represent the time left for something to complete. Like when you wait 7,5 minutes for the bar to reach 75% and then it suddenly jumps to 100%, instead of taking another 2,5

That's somewhat similar to my second mini-project of my NLP course (that I just delivered like one week ago). What we had to do was, first to gather a large corpus (in this case) of portuguese. Then, produce the frequencies of each unigram

Debbie's problem is exactly what makes me use the Friend Lists feature of Facebook. It might not protect your data that well, but at least it is able to keep things semi-private from the (less tech-savvy) friends of yours from other social

It might not be that clever, but it is able to considerably reduce the running time of the algorithm (even if the speedup in a 9x9 puzzle is not perceived). In fact, if you ask people not from a CS background to explain the steps they would

Yeah, but I can't think of two similar actions where it would be difficult to define the expected behavior: sometimes you just take one bud out momentarily to be able to listen to something external and you don't really want the music to st

As far as the article goes, this new solution could very well be just a different version of the Simplex method, which can also solve this kind of problem. As some already said: better article needed.
