NARAS vs. the RIAA

Why should they care about the artist? They are in business to make money by any means necessary....
They should care about the artist because without them, they would have nothing to sell!
... The RIAA says "Its for the artists", but that has proven to not be the case....
You're absolutely right in two ways, depending on what "it" means.
First, the reason they can even exist is because the artists keep doing their job making music, then they try to make a few bucks by selling it. Without the artists, the RIAA would have no new material to sell, and they would die very quickly. Because of this they should care VERY MUCH about the artists.
Second, this whole about "protecting the artists property" is a load of crap. I don't claim to be an expert on how the industry works, but from what I understand, the artists sell their rights to the record companies, who then make CD's and sell them to consumers. If I'm right about that, then they aren't protecting the artist's music, because they don't own it any more!
I'm also a student at RPI, but I'm a year lounger than you. The laptop for the freshman that year was an IBM T20, which I still use. It's also common knowledge here at RPI that the laptop batteries will not last more than a year and a half unless you're really lucky.
This comptuer has performed as well or better than the other computers I've ever used, except that I have this exact problem with the battery. Until about a year ago, my bttery was fine, but i noticed that over the summer, it didn't last longer than 40 minutes. Now, 6 months later, its life is approximately 20 minutes before giving me dire warnings about losing data. I wish that RPI had told how to use the batteries so that they would not die like this. All they told us was that if we started discharging the battery, let it fully drain.
That's the exact same thing I was just wondering. The best way for me to find out is to go build one and try it! I'll be sure to make a website once I do it, and after that, I'll try to stand up to the litigation from Pursuit Dynamics:)
Seriously though, it looks like there's a small venturi at the exit of the steam chamber which would focus the steam backwards and start the process. Also, if you don't have steam pressure (any time the boiler is off overnight), the water will flow in the steam supply line. When you start it, the steam probably pushes the water out, generating a small current that builds as the engine starts working.
This is the most promising way I've heard to scale the horsepower up! It looks to me that the functional part of these engines could be made from 3 or 4 parts that simply bolt together (2 of them could even be press-fit in place). This would mean that the cost of producing them would be very low (in comparison to a regular outboard). Connecting the air and steam supply lines would be the hard part, since each little engine would require its own. I can definitely see a boat with a row of these things along the bottom speeding along the water:)
The design would require revamping most current hull designs to accomodate an intake for better waterflow to the motor....
Well, there are a lot of jet powered boats on the water right now. This is just a new way to create the pressure necessary to move the water and push the boat forwards. Guessing off the top of my head, I'd say that making a retrofit to existing jet-powered boats would not be a big problem at all.
Also, how big is the motor? It might be far too cumbersome to fit in anything less than a 20 foot boat. How much does it weigh?
Boilers can be pretty small - definitely no larger than the engines that currently take up space (and I'm referring to inboard motors as opposed to outboards). If you're referring to using a reservoir to hold the water to be boiled, why not just use the lake / river / whatever water to boil? True, salt water boils at a higher temperature, requiring more energy to create the steam, but I'm sure that if the boiler is powerful enough to creat the amount of steam it needs, it could handle that extra energy.
I think I might try to build one for my 12' aluminum boat:)
I wonder how easily I can make this in my school's machine shop. Probably with a few days of free time and a $30 of stock, I can make myself a motor that won't hurt the mutant fish in the Hudson River.
Thanks for giving me something to do in my free time!

Just take a look at the music you download now. Sure, you may occasionally and self-righteously download the occasional legitimate "teaser" track released legally, or some free songs from no-talent "independent" artists who are giving away their wares because no one in their right mind would pay for them. But you know that almost all of what you download was recorded, produced, distributed, and marketed by the very recording companies you claim to despise, and would never have been committed to disc were there not the possibility of profiting from exclusive distribution rights to their product.
I don't know about you, but about half of the non-radio music I listen to is very eclectic. The rest of it is the stuff that the RIAA tends to sponsor.
I also find that when I pay $15 for a CD, I only ever listen to maybe 3 of the 12-20 songs on it (with a few notable exceptions), and most of these songs I have never heard of in the first place - for good reason. I don't like paying that much money to get only a few songs.
Look, I'll be honest. I, like most other people here, have downloaded pirated music from the internet....
... Any country which offers them safe haven should be considered a rogue nation and isolated internationally, and considered a sponsor of terrorism....
If it is still a protype and experimental then why don't they just wait until it is far more developed...
Well, the fact that it's considered an experimental aircraft does not necessarily mean it's unsafe. Just by the fact that it's flown (tethered or not) I'm sure that they've gone through the design process many times over.
I used to fly Cessnas, and while I was at the airport, I'd frequently see a canard-style plane that was rated as experimental simply because it was a kit plane and the owner built it in his garage. The plane was not unsafe; the owner told me that it had excellent stall characteristics, that it gave a smoother ride than most conventional small planes he's been in, and that it was generally easier to fly because it had better visibility in all directions. Also, a friend of my father is building an amphibious plane in his garage, and once he gets it flying, it will be also be considered experimental simply because it's a kit plane. The plans for the particular model he's making are constantly changing, and many of the minor changes are his doing because he found better ways to build it as he progressed.
Sorry for such a long post, I just wanted to clear up any confusion you had about 'experimental' meaning 'untested', because they are VERY different terms.
I'd like to have one, but what's the point if its illegal to taker 'er out for a spin?
Being classified as an experimental aircraft, it'd be legal to take out for a flight, but you would have to have the appropriate pilot's certificate (My guess, as I'm still waiting for the pictures of the thing to download is a 'rotorcraft' endorsement).
I also can't wait to see the outcome of this fight.
Frankly, I agree with the "Alliance for Digital Progress," as they're calling themselves. They just don't want to slow down progress by putting digital copy prevention in every product (according to their site.
Yes. pirating happens, but the movie industry is still very strong (and if you don't think "Kangaroo Jack" netting $21.8 million dollars in a weekend is strong, then you need to have your head examined:). Digital piracy - from what I've personally seen living at a RPI - is not such a big problem. There are movies floating around the campus-wide network, but most of the movies I've seen since I came here in the fall of 2000 have been off of a DVD, on TV, on the campus movie channel, or off a videocassette.
Except don't some locks you buy in DIY/home stores come in systems? They'd probably have a master key in the series for the lot of them.
Not really. Most "cookie-cutter" locks are keyed similarly because it's cheaper to manufacture them that way. Most of the time, they do not have a master key, otherwise the police could and would have them (there's only so many different manufacturers of locks) so they could:
1: Help people who lock themselves out using their master keys.
2: Get in doors that are locked for whatever other reason they have.
So no, the lock on your door is most likely to not have a master key for it, and this exploit does nothing to compromise your home.
Because this makes finding the template for a master key a relatively fast, simple, and reliable process.
Imagine having an office somewhere and being able to get in everyone else's offices using nothing but your own key, your own lock, a few key blanks, and a file - over a lunch break.
If you've ever seen someone try to use a lock pick, you'd understand why this is a bigger security hazard than lock picks and other exploits. It doesn't look suspicious when you're trying it out.
Actually, it requires momentary access to a single key; authorized or not (you could, for example, get a key by attacking the insecure area where it's stored, say, in a jacket at a night club).
Having more keys is handy, but not essential.
You should read the article before trying to correct someone on it.
The method referred to in the article does in fact require access (although not much) to a lock and key in the system.
You don't technically need the blanks, because you can make them if need be. But you do need access to the area so that it's not suspicious when you go there and try a your template keys.
You can, like you said, make a copy of the first legitimate key and go from there, but it's easier to have the original - which is what the discoverer (and I use that term lightly) of this technique had in mind.
In some cases it would be just as easy to get a copy of the master key as a regular key (rob the person who has it), but if you have a key in the first place (if you work in the office, or live in the dorm, etc) you don't need to steal one.
It's trivial to make an impression of a key and then cast your own blank. Metal casting kits are available for little more than lunch money at any decent Hobby Store.
True, but that's a completely different method than what's in the article.
For example: I made a master key for my dorm out of a broken CD. I got the master key from an RA for 30 seconds, made an impression, and gave it back. From there, I cut a CD to the pattern, put the template in the lock, and turned it with a screwdriver. It worked on 2 other doors before a friend broke it in half. It worked, but the method here describes a way to find the pattern for the master key without even needing access to it. I could have made my master key using brain power rather than skill with a razor.:)
> Use distilled water. It's non-conductive.
Better yet, use deionized water.
Just be sure to change it every so often so that it remains deionized.
Actually, don't even worry about it. Just make 150% sure that you have excellent soldered joints on the copper (which is much, much more conductive than water) so that the water doesn't leak on the rest of the power supply. If it doesn't leak, it won't be a problem.
Yeah, just because someone doesn't know how to set up a website properly (I sure don't) doesn't mean that they can't safely configure a heat transfer set-up.
Also, looking at a glance, the pipes he's using have the ability to transfer much more heat than the connections to the hot components. I'd probably use smaller pipes with better thermal connections myself.All in all though, this looks like a good idea for my noisy power supply:)
Oops, I forgot to add that I have used Gnutella, and found that it is very slow and returns many more irrelevant results than good ones.
Sorry, I'm a newb to/. and am not used to making intelligent posts:)
Maybe someday someone will go after some of the people on IRC, but there just isn't enough manpower to get everyone, so I'm not worried about it. Also, I didn't know that one of those clients actually existed . . . thanks for telling me!
As long as there are files to be shared, people will find ways to share them. Napster is down, Scour is down, now Kazaa will probably go down.
I guess it's back to using IRC until someone figures out how to make a free, open source P2P network that costs nothing, isn't incorporated, and doesn't rely on a central server so that the courts can't sue any single person. Hopefully it will last longer.
