2) Still don't believe me about "melting is a cooling process?" Take a shower and get out, but don't dry off with a towel. Notice the water evaporating off your skin? Feeling cold? That's due to the cooling process of the liquid-gas phase transition. The water is turning from a liquid to a gas, and in the process taking heat with it.
YES. Melting IS a cooling process. In the same way, boiling is a cooling process. Don't believe me? Stick a thermometer in a pot of boiling water. It will remain constant at 100 F even though you're adding heat. What? Huh? The only way for the temperature to remain constant while adding heat is to go through a phase transition. The liquid-gas and the solid-liquid phase transitions are endothermic, they use heat in the reaction. Freezing is an exothermic reaction:
I meant fahrenheight, but I was just guessing at that number. I do not know what the average temperature of the earth is, but it should be pretty close. The exact number doesn't matter, what's important is that it stays close to it year after year in an equilibrium state.
It seems some of you have never taken High School chemistry. If you have, you'd know that any stress applied to an equilibrium system will be counteracted by an opposite process. For instance, if you heat up ice, it will melt, a cooling process. If you freeze water, it will give off heat, warming itself up.
It just so happens that the Earth's equilibrium lies at about 50 (give or take, it's different for different parts of the world.) Now, whatever we do, be it release CO2 or keep matches lit, the Earth will not increase its temperature significantly until it has exhausted its ability to cool itself, namely, melting ice. Thus, the only direct indicator of global warming is the elevating sea level, not the change in temperature.
However, it is extremely hard to measure this over a long period of time, but another way of predicting warming is looking for changes in weather patterns. If a location gets 10 times the normal amount of rain two years in a row, you know something is wrong. If an area becomes dry and arid when it used to be damp, something has changed, most probably due to our influences. Why? While melting and freezing ice will hold an equilibrium steady at a certain temperature, the Earth is a gigantic closed system, and thus requires a large amount of mixing to transfer heat from one location to another. Thus, rising temperatures need to be transmitted to the poles for equilibrium to remain constant, and the Earth does this through weather patterns. If the temperature changes, so do weather patterns. And the frightening thing is, they are. Quite a bit too.
Just saying that since the temperature hasn't risen, there is no global warming, is an utter lie. The temperature won't rise significantly until all the ice at the poles has melted.
most good new games don't adhere to any genre whatsoever; instead of giving examples, look at the games that do stick to one genre; they suck. First person shooters are over, what we have instead is max payne. Genres are boring. As soon as enough games are made of a type, a genre is created. Thus any game that falls into this catagory after its creation is tried and old. Now that the tech bubble has burst, companies are forced to release good games, ie genre busting, or else face the concequences. We will see less games, but ones of better quality and of more varied type.
You don't understand. I mean a root level system integrated phone built into software and hardware. Computers just don't do that. Those programs you mentioned are third party, and furthermore, are not for mac os x. That aside, granted, you can turn your computer into a phone. However, how many people do you know do that?
That article brings up an interesting point, about which I have been thinking for a long time. Computers are able to do anything a television or phone can do... except 99% of them don't. That is, not without extra cards and hacks, and even then, I haven't come across a phone card for my computer. So why do we still use such outdated devices when we could be using only our computers? 80 GB of answering machine tape would be nice...
In the same way, who would have ever thought two years ago that you could use a tv box as a phone? We don't need TVs that are also phones. The same task can be done with a computer.
however, that competition might not be good. Look at all the consumer formats we have... DVD-RAM, DVD-R, DVD-RW, DVD+RW, and pretty much any other combinatin you can think of. This blue laser stuff has the potential to be just another format, in a manner much like the solid-state storage format wars a few years ago. Why can't the industry agree on one standard?
that sure would. however, now that I think of it, is this new sony recorder the only device that can read it's media, or can other dvd drives read those huge disks? I'm wondering because I have a hdtv reciever and direcTV, which only offers 2 channels in HD format, but when they offer more, this device would be perfect for storing shows in HD. In fact, the website pointed to in the topic says this, indicating that the burner writes in real time. How is that possible? If it's true, double cool! If I could transfer a HDTV signal from this baby to my computer... actually, I think you can. It has a DV port on the back, but it wouldn't really be HD.
Ok, now that I think of it, this device has a LOT of potential. It could bridge the gap between the TV and computer with just a few more ports on the back.
23 GB for a 30 dollar disk, or 5 4.7 GB for 5 bucks... hmm
However, if and when the price goes down, I can imagine dvd distributors going wild over this format. The lord of the rings collectors edition might even fit on one of these disks...
Looking at the back of that thing though, it doesn't have firewire 800 (or even 400 for that matter,) a must have for any DVD burning device.
the point of Drake's equation is not really to find the probablity of life. In fact, it shows just the opposite, that it is impossible to show such a probability. It is meant to show just how many variables go into the possibility of life, which, I think, is kinda interesting. In any case, it can't be applied to such a small scale. Drake's equation applies to galaxies and the universe, not our local solar system.
Also, since when did intelligent life exist on earth? All I see is war war war...
if this becomes popular, we can forget about that global warming thing... however, a perpetual global winter wonderland can't be a good thing either. oh well, screw the globe, us here in Berkeley can finally have snow.
The temptation to misuse this must be over the top. I can imagine dorm rooms and frat parties filled with snow. Imagine waking up under 2 feet of snow in your dorm room. hehe, college is going to be fun after all!
While email cannot legally be sent unsolicited, there are millions of such messages each day. So why isn't the government doing much about this growing problem? The bandwidth gained back would be well worth the effort, so why hasn't congress passed laws against email spammers, who for the most part are based in the US?
A few days ago, The SF Examiner cut 90% of their workforce. Now Salon makes another grim statement... two of the main San Francisco sources of news look like they're going under. Kids, now's not the time to major in Journalism.

H20(l) --> H20(s) + heat
you, sir are wrong.
so microsoft is paying for ideas now?

yay! finally! my mac is faster!

"osiris" looks most impressive. Photorealistic even. Absolutely amazing. It's even better than FF. And that girl is damned hot :)
Since when is 1280x1024 HD? 1080i is 1920x1080. ATI has made a similar device for a while now.

Why haven't I heard of this before? Don't tell me they built one just for this orb thingie. I want to connnect to it using my TiBook!
Also, they'd better start working on their lip-syncing, it's quite horrible.
I already memorized the Tom Leher song.
holy crap that's a lot of storage space! 10K? Nobody is ever going to need that much!

if only this had come in the age of the disco... endless possibilities! Now, I can't help but think this will go the way of the segway.
