Agreed. Usually windows (on the desktop) breaks because people install and uninstall crap non-stop with no idea of whether or not the programs are safe. Then they wonder why settings got screwed up. Gesh.
Several times faster if you are doing the same small subset of functions repeatedly. GUI is still great when you aren't even sure what exactly the thing you are trying to do is called. Command line seems faster for IT pros because well they've amassed a substantial of different commands in their memories. But take a windows admin (not the helpdesk dude but a real windows sys admin) and they'll do just as much crazy crap with a odd mix between command line and GUI as a unix admin does on a term. All in what you are used too. Give a random fiber channel card to both admins and have them figure out how to configure it for their SAN. Chances are the win admin will be done and having coffee and the unix admin will still be reading man pages trying to figure out what flag they need to set to get feature x working. P.S. I'm a UNIX admin mainly so if anything I should be biased in favor of UNIX but in terms of productivity for the IT guy I think windows wins. *NIX once you figure out how to do what you are trying to do is usually more robust though. Kind of like the difference between a dynamic typed scripting language and C programming, scripting person will likely get something WORKING quicker, C programmer will likely get something that RUNS quicker.
Yep. 1Gb symmetric is what we really need. It is silly all these extreme high speed providers coming out that still give you a proportionately crappy upload and usually usage quota. What good is 50Mbps if you have a 50GB monthly quota, so you can only use the internet for a few hours a month. May have been okay back in the mid nineties with 1 computer in a house. But with more like 3 TVs, 2 consoles, streaming TV etc in a typical highspeed house it is very unreasonable to expect/require the network to be idle most of the time.
How they say in the article that the satellite remains US property. Yeah okay, if their junk lands in my backyard (Canada) I think I'll keep it. Seriously how are they going to enforce that if it lands somewhere not in the US? I'm sorry but if your junk lands on some other countries soil they can do with it as they please.
You might be right. To me though gamers always want something more powerful, emulation/browser based isn't going to be it. For moderately good graphics there is already a huge number of things, silverlight, java, flash, etc. They really shouldn't be able to call it a native interface, yeah it is an interface from native but that is like saying "we can take your really optimized program and running in a crappy emulation layer, woo hoo.
What is the benefit other than porting native apps to run in a browser? The article linked to says that the Pepper interface is a binding layer that converts the native calls into stuff that can be done in HTML5. That's great but... native apps will now be limited to the performance of the HTML5 engine unless I'm missing something. So yeah you can get platform independence as long as you are willing to have an interpreted layer between your code and the OS. Isn't that the same thing Java gives you? How about Windows game developers Direct X support etc? Are developers really going to just throw that away and redesign things to perform well on an interpreted HTML5 interface rather than port the program over to a web language entirely?
Beware many/most physics majors can't handle GR at an undergraduate level. It is usually a senior level elective which only a small subset of physics majors take (mainly because it is rather difficult and it is more productive finding girlfriends in a psych course:-)).
Anyways for when I took GR you needed to have an understanding of tensor analysis. This was covered in our 6th course (yes sixth we took more calculus than the math majors). So you'd want an understanding of basic calculus (derivatives, limits, integrals). Then move on to differential equations and vector calculus (particularly line integrals, continuity equations (Green's theorem and its physical consequences). Then off to tensor analysis which is really just the vector calculus equivalent to differential equations. Then you can happily do classical GR.
That said as other people mentioned a lot of things are just concepts and there are several lower level introduction to the concepts and consequences of GR. Also if you don't care to know how to derive things in GR then just skipping to the final formulas in a lot of texts will help. Ie what is the time dialation between a guy this far from a star and one that far, etc. Ultimately for simple geometries at least you end up with just algerbraic formulas that you can plug values into, if you have more than 2 things in your model universe then the problems aren't solvable by math (seriously it is that complicated) anyways and you are back to the first principles and simulations.
Speaking of censorship I took acting in highschool. I "mimed" swearing and got dinged marks. I must have mouthed the word really well for them to be able to tell what it is but still I was dinging despite the clear proof that my acting was good:-)
Because none of the races that ethics boards care not to offend would be upset with those words. When you are the majority you are fair game to pick on because obviously no one can give you a hard time and discriminate against you because you are a member of the majority;-)
Not to mention a lot of those words are only objectionable if they are used objectionably. Someone doing a study on rape could get filtered because they mention anything to do with sex. Appropriate words for anatomy are being blocked even though there is nothing offensive about them by themselves. Speaking of which: sex ed: why do we teach kids about sex but not about how to enjoy themselves? We get taught the anatomy and the process of child development but nothing about techniques what areas are enjoyable or at least worth trying out, alternative means of pleasuring each other etc. I've seriously dated a few girls in university not highschool, that weren't virgins had never had an orgasm, never done anything other than straight missionary, never saw a guy ejaculate (because they always came in them, I meant it when I said only missionary) etc etc. All they learn t in school was the anatomy they didn't have any clue in how to figure out what is pleasurable for them (or even a clue of how pleasurable it should be to let you know if you aren't doing it the way they like) Dear God, kids will have sex they might at least learn how to enjoy it. I'm dead serious here, why can we talk for two weeks about the menstruation and gestation cycle but we can't discuss blowjobs and cunnilingus when those are two ways of getting each other off without risking pregnancy?
Not to mention at some point there will be so many large sites out there that it will be hard to get enough of an audience to use a advertising revenue model. There is only so much marketing money out there and it is by definition a faction of companies budget.In my mind if your product provides real value than people should be spending real money on it even if it is larger than their marketing budget.
Back to physical products: quick death not so sure. Processes to build them could be used elsewhere and companies need to be able to keep things around long enough to find a product that can use the components profitably without giving up on each innovation as soon as it isn't an immediate success. Hence the need for patients.
Exactly. Closed but does what I want is better for Joe-pubic than open but crashing all the time or requiring commandline intervention every other install. There are upsides and downsides to it but if you are the average person and can't program than having access to the source doesn't help.
Not to mention that the parents having a couple hundred kids or more per school to find sitters for for one day a week during the school year probably costs more than the $50,000 saved.
In my experience shitloads are always using the imperial measurement scale.
I agree with your post though, in general I don't think anyone wants to be the one to invalidate thousands of patents held by Apple, Microsoft, Oracle, IBM etc. Huge political fallout: "Oh you are ruining american competitivieness, etc etc". Imagine the dreamland that people wish to live in where you can export all the manufacturing to the developing countries and keep all the patents, trademarks etc in the US. Oh crap you mean all those hordes of engineers/manufacturers etc that we built up can now copy our programs? Oh crap.
I'm sure there are resources that might want to go back and forth near each end of the tunnel, but in terms of shipped goods? Not really. Most of Russia's population is on the other side of the country. Most of America's is to the south. It takes over 6 days to get across Russia by rail, and probably a few from Alaska to Vancouver and longer for other parts of north America that are heavily populated. Is rail really that much cheaper than a huge container ship?
Tolls for other countries to use it might be worth while. For example asian countries using the Russian end to get stuff to NA but still in terms of actual benefit to the two countries based on their trade with each other I don't see it. Trade between the countries is only 32B, and a lot of that could be coming to or from the east coast from parts of Russia near Moscow so train wouldn't help. Sure trade would probably grow, but how much will it grow? Alaska has a tiny population as does Russia near where the tunnel is going to be (two closest "states" have a combined population of 450k). So I doubt there will be a lot of tourist travel. After all if you live in that part of Russia it looks a lot like Alaska and vis versa. If you live elsewhere in Russia/America you want to see something else likely in the respective country (Las Vegas, LA, NY, etc, and Moscow St. Petersberg etc the other way).
Wow, a typo and several people have a correction. Fantastic if only Word worked as well thanks. Yeah, I was too busy studying nuclear physics to spend much time worrying about english lit sorry. Back to your books boys.
Exactly. Self defense has to be just that. The violence is only legal if it was necessary to defend yourself. If you could have just walked down the hall then it wasn't necessary. That said I think sometimes people need the shit kicked out of them to teach them a lesson. There might be consequences to being the one giving the lesson but it also has it perks too;-)
Since when are school rules laws anyways? A school says no soda. Okay but then a cop gives a ticket and a court date? What the heck. I think schools should be the same as a workplace. A workplace can have a rule no fraternizing. But dating someone at work isn't a crime (unless it is coerced) so your employer has to handle it with their own processes not pass it off to the cops. Should be the same way in school. There is no law against running in the hall, there is a school rule though.

Not to mention that if something like Google TV takes off then you might be streaming HD to multiple TVs at the same time.

Yes because blind people would rather masturbate to dead silence than a bunch of Tokyo cougars moaning away.
Ah, so only poor riffraff would be interested in seeing naked women. Oh how naive.
