Maybe you're right... But I think you're forgetting something: human space exploration has values beyond the purely rational. Kennedy didn't propose putting a man on the moon because it was useful somehow, he did it to inspire his people, to win the space race against the Soviet Union, and to win votes in future elections. Just look at this speech - if Obama or someone else manages to put together a piece half as inspiring, then I think we will have a human on Mars within 15 years: http://webcast.rice.edu/speeches/19620912kennedy.html
That's a very valid point. Astronauts are versatile and orders of magnitude more useful for doing science in situ, but are also orders of magnitude more difficult to transport and keep operational there. Just the little matter of having to return to Earth poses a pretty big challenge.
On the other hand, if we keep limiting human space presence to low earth orbit then we'll never lower the barrier of getting humans into space - and that's where we want to be, eventually. Unmanned vehicles have their time and place, but they will only take us so far. It's like when airplanes replaced ships for long-distance travel - the planes were more difficult to build (and still are), they had many inherent weaknesses such as the need for long runways and tight security (still true), but in the end the pros outweighed the cons and we learnt how to handle the problems. That's what I hope will happen with human space exploration as well. Even very difficult problems can be solved if the gains are large enough.
I think we're quite a bit farther away from making robots as useful as humans than we are from launching a human mission to Mars.
As awesome as the rovers are, they're hopelessly, frustratingly inefficient. It's hard to control something located a dozen light minutes away. The total distance traversed by Spirit is 10 km and by Opportunity 27 km. Every single movement must be carefully planned before uploading the command so the rover doesn't get stuck in a sand dune or fall off a cliff somewhere. All the progress made by the Mars rovers in six years could probably have been accomplished by human astronauts in just a few days.
I bought a Sony Ericsson 8 years ago that had video call capabilities. I didn't even try it once, and it never took off anywhere in the world despite a huge number of phones and networks supporting it. Instead, people used the extra bandwidth to check their mail, surf the web and download ringtones and themes. Last year Apple tried with FaceTime (does anybody use that?) and now it's Google's turn. I don't see that it will pick up this time either.
Kind of funny to see that this feature, which for so long was believed to be the communication of the future, turned out to be a fiasco when the future finally arrived. Apparently we just don't want to see each other when talking on the phone.
Well, trouble is it doesn't really make sense to use evolution by means of natural selection to get a desired result. Artificial selection, like breeding dogs or horses, that's a good tool. But natural selection has no purpose or direction - it could just as well have created nothing but bacteria for 10 billion years until the Earth perished. If God used natural selection as a tool for creating humans, he must have tweaked it all the time, making these two individuals breed, making this asteroid hit the Earth at the right time and so on, effectively making it an artificial selection. While certainly possible - we're talking about an omnipotent being here - it would be an incredibly awkward way of running things.
Many people claim to believe in both evolution and God, but if you truly understand not only the first part of the theory (evolution) but also the second (by means of natural selection), then that should have consequences for your faith. I'm quite intrigued as to why more people don't talk about this issue - Richard Dawkins, for instance, has said it is this very insight that caused him to become an atheist. It's hard to combine a full insight into darwinian evolution with a belief in a god that created humans. In my experience most religious people simply don't understand or don't care about the theory.
The theory of evolution by means of natural selection was presented to the world in 1859. It has been widely accepted among biologists for at least 100 years, and has gotten even stronger support with every new discovery since then (genetics, chromosomes, DNA and so on).
From a scientific point of view, there is no controversy. Evolution is right and creationism is wrong, simple as that. Teaching creationism isn't presenting both sides of a controversial issue - it's lying to the students. This bill explicitely says "This section only protects the teaching of scientific information", so creationism should be exempt from its protection since it is, legally speaking, "not a scientific theory" (see McLean v. Arkansas 1981, Edwards v. Aguillard 1987 and Kitzmiller v. Dover 2005).
If the bill is intended to protect teachers who want to teach creationism or intelligent design, I highly doubt it will achieve its purpose.
I don't agree with you. In fact, I think we should have legislation that explicitly forbids arbitrary collecting and tracking of private information.
We're on a dangerous path if we allow anything as long as it's voluntary. Don't like to be tracked? Just don't visit the site! But what happens when more and more sites come with privacy policies that you don't agree with? You might not be able toavoid them all. Chances are you're required to have a Facebook or Google account to keep your job, and suddenly it's not all that voluntary anymore.
Sometimes I don't get how the same people who worry about government snooping and Big Brother happily put their entire life on Facebook for everyone to see. You should be less worried about the FBI and more worried about Facebook who owns your photos, Google who can read your mail and your local supermarket who knows what you buy and when. These aren't trivial issues. You should think about them.
Disclaimer: I'm a member of the Swedish Pirate Party, and I've been so for a few years. I've voted for them in the three most recent elections (two for the Swedish parliament and one for the EU parliament).
I definitely believe that this is a good move. Rickard Falkvinge is a very charismatic person, but also a controversial one. He's enthusiastic, he knows how to reach the headlines and has done a wonderful job of founding the party and establishing an awareness of these questions in Sweden. The problem is that he lacks political tact. He's committed at least two really bad faux-pas, one statement in which he defended the right to keep but not buy child pornography and one time when he asked for personal funding from the party members, suggesting as they would be gifts they didn't need to be taxed. On top of that, there is a common view that the Pirate Party is Falkvinge's own private project and that he is something of a cult leader.
Therefore it is great to have Troberg on board as a leader. She is less technical and more personal than Falkvinge, but first and foremost she's much better suited to running an organisation than Falkvinge ever was. She will be able to handle people without driving them off, she's competent and she radiates credibility in a way that a party with the word "pirate" in its name needs desperately. Falkvinge was great for kick starting the party but Troberg is just the right person to take it to the next level. She has a tough job though - the party flopped in the 2010 elections and without a lot of hard work there is a risk the party will dwindle and be largely forgotten well before the 2014 EU parliament elections.
Do you guys actually have multiple-choice tests on university level? What's the deal with that?
I never had any multiple-choice tests while studying for my M.Sc. degree in Stockholm. You had to give elaborate answers complete with calculations on every single question. Sure, it must have taken a while for the professors to grade the exams, but it made it virtually impossible to cheat unless you managed to smuggle whole sheets of paper. Even if you knew the exact answer to a question it likely wouldn't be much help if you didn't know how to arrive there.
Do you think Amazon would be happy about an article like this?
Problem is, when you get a big sponsor you lose some independency. You lose credibility. Random ads showing up on the pages? Fine. One big company that has the power to shut down the entire site? Maybe not a very good idea.
A conflict of interest is bad not only because what could happen, but because of what you suspect could happen. Maybe Amazon would tolerate the negative article, but let's say it got changed or removed for some reason. It could be perfectly legit, but everyone would suspect Amazon had something to do with it, so Wikipedia would lose credibility.
I think if Wikipedia decides to do ads, it needs to do it in a way that doesn't in any way compromise the integrity of the articles.
If you don't trust your IT people, they shouldn't be your IT people.
I think the managers sort of realized that, and that's why they fired her.
Maybe the true lesson to learn is this: don't let former employees keep their access. Not even for a few days.
Well, sometimes the "freedom to choose less freedom" isn't a good option to have. Chances are it becomes more or less mandatory.
Let's say for example that my employer wants to install surveillance cameras to see how well we're working. I'd say "no way" and start working for another company. But when that company starts doing the same thing, and then the next, then soon I might run out of jobs to apply for. This way a pressure is created to accept measures you're uncomfortable with even though it's still voluntary on paper. Some things just shouldn't be allowed, even if both parties agree on it.
(OK, so a locked-down music player may not be the end of the world, but you get my point.)
As a matter of fact, silicon is not primarily used because of its low price - even though that IS a factor - but because of the excellent electrical properties of the interface between silicon and silicon dioxide. The silicon is a good conductor when doped with boron or phosphorus, the oxide is a very good isolator, and the interface is extremely smooth. The oxide can be grown to any desired thickness in a process that can be tightly controlled. All this means that the silicon technology scales down better than that of any other semiconductor.
Gallium arsenide, silicon carbide and several other semiconductors are used in many areas due to their particular strengths (most notably the direct bandgap of many III-V semiconductors makes it possible to build solar cells and diodes out of them), but when it comes to making very, very small things, silicon is king.
Hello and welcome to Sweclockers! Today we're looking at UEFI, the boot software that is the successor of the old but still very popular BIOS. UEFI has become a hot topic recently as it's going to be used extensively in the next generation of Intel processors, codenamed Sandy Bridge. So let us have a look at what it has to offer.
The biggest difference between UEFI and BIOS is that UEFI gives motherboard manufacturers much better possibilities of implementing their own software. Our test motherboard comes from Asus, and the Taiwanese manufacturer has put in several exciting new features. To begin with you can use your mouse, which wasn't possible in BIOS, and there's also the possibility of running in several different modes. For example, there's this simplified mode that greets you when you enter UEFI. Here you can choose between power saving, normal setting or some kind of optimal setting. All settings are then adjusted automatically and you don't have to worry about it. Then there's this simple drag-and-drop system to choose boot order and some panels are available that show fan speeds and the like. Very simple and absolutely enough for anyone without any desire to dig into it.
There's also a more advanced mode available through the menu here, and now it looks more familiar compared to BIOS. It works more or less the same way except the graphics are updated and there are more options. There are several menus available where you can change language, security settings, and there's this "AI Tweaker" where you can overclock the processor, just as you're used to from BIOS. The usual advanced settings for integrated components such as the processor etc. are there, and they work just as usual. The monitor settings where you can see temperature, fan speeds, set fan profiles and so on, also work just as in BIOS except it looks better and you can use your mouse which makes it easier to navigate. The boot settings contain some new features, for example you can just click one of the alternatives and the computer boots from that device, you don't have to enter a special menu or anything. Finally in the last menu, there are some tools, Asus' flash tool to update the BIOS, which itself is also updated with new features. You can easily use your mouse to pick a BIOS version from hard disks or USB storage that you want to use on your motherboard.
Well, that's just a quick look on an implementation of UEFI for the next generation Intel platform. With the possibilities offered by this new system we will likely see new interesting solutions in the near future. We at Sweclockers will of course cover this development and report as much as we can until the final release.
Not that anyone will likely read this now, but for the record, the above post is no longer true. Earlier this week I bought my first app from Sweden's newly opened non-free Android Market.
Another way in which Android Market sucks is that it doesn't offer pay apps in all countries. In Sweden where I live it's impossible to download any app that costs more than 0 dollars. This leads to me not being able to use my new expensive smartphone to its full potential.
There are ways to circumvent this using foreign SIM cards or rooting the phone but that's rather cumbersome and I don't think I should have to do it. Come on Google, I want to pay money. It's the biggest no-brainer I've seen in quite a while.
If Amazon offers a way of paying for apps in my country, I'll be their first customer.
Clearly driving is just too easy and minds wander too much. If we made roads more challenging like crazy golf courses we might fix the problem (and create new fun problems to solve).
This is not as stupid as it sounds. In many countries highways are deliberately made to go over hills and crests, always twisting and turning slightly rather than being straight. This makes it easier to concentrate on the driving and keeps the drivers from falling asleep at the wheel.
