that the longest surviving soviet probe transmitted for only 65 minutes. I feel that you're over-romanticizing landing on Venus a bit here, also lets not forget about the atmospheric pressure (93 bar) and temperature (462 C; 863 F), at the surface, not the easiest conditions to operate machinery in for longer periods of time. (src: http://astro.if.ufrgs.br/solar...) ESA's Venus Express did some good science as recently as 2015. And you didn't mention the weird retrograde rotation of Venus (together with Uranus, the only ones in our solar system), which is one of its most interesting features in my personal opinion..

not a real info :P * Brazilian government is well known for use FOSS (here, some links for you: http://serpro.gov.br/ / http://ccsl.ime.usp.br/ / http://softwarelivre.org/ / http://www.ufrgs.br/soft-livre... [sorry: all in pt_BR...])

I'm surprised no one else has posted this, but the address of the actual test is

You have to register, and fill in a small survey consisting of your experience with image manipulation, but its still up as of this post.

A good way to mix both techniques is Relief Texture Mapping. It's a good way to get smooth surfaces thanks to the texture interpolation hardware, with no extra polygons.

Yep, sharing is the key, that's why I GPL'd my robotics simulation system (that I used for my masters degree). If you want to help improving it, or just want to use it, take a look at:
http://www.lec.ufrgs.br/~dmbasso/phi (under development) and
http://basso.inf.br/phi (now obsolete, the version used in my thesis)

http://www.if.ufrgs.br/~jgallas/gaston.gif

No idea if this is the one you mean exactly, but the results match. They call it relief mapping.

On a side note, it is fun to see how demo images can have error (bricks do not match in the corner of the burning barrel image). Please, if you want to show how cool is hot air distortion... make sure other graphic details are fine too.

I've studied 2 years Mechanical Engineering in UFPR.

I'm not saying they doesn't exist, but i never seen a Linux Desktop there. 6 months before i've stopped to study there they changed from NT to Windows 2000. Computers with 500mhz running Windows 2000, that computers could be much more productive to students running linux. Of course in Mechanical engineering you need to run programs such as Solid Works, but many computers would be much more usefull if running Linux.

The computers department of UFPR may look at Universities like UFGRS(also here from brazil) witch changed to Linux desktops(in UFRGS there's something about 4000 computers running linux).


In one of the computers rooms for 1 year we have a paper written: "don't execute xxxxx.exe because it's a virus", security was a joke, 10% of the computers are always off because they are with virus, whem the computer was woth Windows NT people goes to the back of the rom and hit "esc" to login and start to do "wrong things"

etc etc etc etc etc etc

True, ISPs should help make the Net idiot-proof, but some ISPs also see their main job to make more $$$.

Therefore, with the increased number of users with more bandwith than brains, the Net will get bogged down and ISPs will start thinking "What to do? What to do?". Sure, they might want to help average-Joe, but they also want to make a profit.

Consequently, it is my solemn prediction that we will see a lot more QoS stuff going on. I.e. ISPs will try to make more money be offering "dedicated" services or "garanteed" bandwith to those with more money than brains (or to those who actually need to use the web for good things). In the end, they will want to implement QoS in IPv6 and charge people accordingly.

So, after they've helped put guns in the hands of children (read:bandwith in the hands of average-Joe), the ISPs will turn around and profit from the plight of their victims. Bastards!

It was discovered in 1991 by the brazilian astronomer Kepler de Oliveira Filho

>>A nuclear plant meltdown makes way less radiation than any nuclear weapon.

>Please support this comment with some references.
The bomb is designed to explode(and thus throw out fissile matter and radiation). Nuclear plants are designed to do the exact opposite, keep the radioactive material in. Shouldn't that change a little about what happens?

>>There are nuclear plant designs which are inherently safer. They shutdown automatically without outside control when there is a problem.

>Try 3mile island and chernobyl.
That's why he said safer: safer than those old designs. Here's one design that works, or how about another.

>>Regarding Plutonium being poisonous do you know Caffeine is more poisonous than Plutonium?

>Plutonium emits nice high energy particles that will kill you. Caffeine don't.Poison is not the question here.

It doesn't matter if you don't expose yourself to the radiation

No Soviet "successes" at Mars until 1971. See here for further details.

There are many chances for such memories to be fabricated. One is through picking up random details from various people over many years. Your parents, siblings or friends won't remember everytime they tell you something--they could have told you about certain events and 10 years later not remember telling you about those events. Another is through others, not exactly remebering the events themselves, going along with your fabrications. That is true with many details.

A good story to look at is that of Child Psychologist Piaget's supposed kidnapping. In this case, his nanny made up the kidnapping and led Piaget to 'remember' the kidnapping. Even in developed brains, details are often changed many times, depending on the listener and his or her questions. That is why eyewitnesses are not always reliable. The level of suspicion towards the authenticity of memories needs to increase as the level of detail increases. Unfortunatley, human memories are extremely susceptible to suggestion by others and the self.
