I run an open source project that requires 1 TB of bandwidth monthly just to serve our downloads.
Can you show me a CDN that costs less than $100/mo for this kind of bandwidth? With our current rate of donations, we couldn't even cover that.
On a related note, we had our downloads server go down a few months ago, and I temporarily put up a torrent in place. Serving our downloads by BitTorrent was so easy and effective, I would gladly use it as our primary or only distribution method if A) there wasn't a perceived stigma against it being illegitimate in some way and B) it was bonehead easy to use and built into browsers, like someone mentioned earlier in the comments here.
Jamendo and Magnatune are great for finding popular music?
Seeing as I'm pressed to find any Top 40 tracks on either website, I would say that they're good for finding obscure music.
(And so we're staying on topic here: I can find tons of classical music on Magnatune. String Quartets aren't out-of-mainstream enough for Magnatune or what?)
It may be peaking soon though. 6nm is getting close to physical maximums for most techniques due to the casimir effect.
Not quite sure what the Casimir Effect has to do with magnetic dots, but I should mention that 6 nm is below the Superparamagnetic limit (which is typically tens of nanometers). That means you're magnetic nanodot probably isn't magnetic.
... Which brings me to my second point: This article says nothing about what this researcher actually did. It sounds like he just fabricated an array of nanodots, which is nothing particularly groundbreaking.
Does anyone have a link to the original abstract for the conference presentation? The dots must have been multilayer "stacks", otherwise there's a good chance they won't be ferromagnetic (there's a "superparamagnetic limit" that stops ferromagnetic particles from being ferromagnetic when they get around this size.)
Lastly, the article says they'll look at housing and using "laser technology" to read back from these nanodots. They mention that as a sidenote, but it's really the most important problem if you want to make something useful. The problem with most nanomagnetic memory techniques is that reading/writing is either impractical or not yet possible.
I'm thrilled that I'm able to use whatever software I want on Android. The problem is, I don't actually want Flash - I just wanted the ability to decide for myself.
So, that's great that you will be supporting it, but please let me turn it off or uninstall it from my phone.
Thanks.
I'm not sure why this keeps coming up, since nobody that ever replies clearly has ever owned an Android phone. My HTC Hero, which supports Flash 7 out-of-the-box, has an option in its browser to disable plugins.
You have the option to disable Flash on your Android phone right now, and it's FUD to keep suggesting that you won't be able to disable it again in the future.
The only way to control your name on the internet is to use assert control over it by using it actively. Make yourself known on the internet in a way you want to be known, so that this oddball reference to you gets buried into obscurity.
Google's really dropped the ball on spam blocking with Blogger too. I host a couple of random blogs on there, and they've all been hit with a ridiculous amount of spam in the last year. Blogger doesn't even give you something like Akismet...:(
I guess we have different definitions of small. If half the Linux users would all send me a buck, I think you might consider that to be a bit of cash.
Unfortunately, it's not your definition of small that matters here - it's Bethesda, id, and EA's definition.
To put this in perspective, remember that there's 30 million Xbox 360 owners out there. If 1 in 20 Xbox owners buy Rage, that'll be ~60,000 copies sold. Show me an existing Linux game that's sold more than 30,000 copies, and you might have an argument. Linux is also a giant pain in the ass to support, and that's undoubtedly factored into their cost/benefit analysis too.
But it is a market with very little piracy of native games. Also, very little competition, so you have a better penetration rate. Not sure if it is enough, but it is substantial.

I was going to say that getting a BSc is definitely worthwhile (if you don't have one), and a MSc will definitely help you stand out when your resume lands on someone's desk. I'm having a hard time understanding how someone with a CS or Software Engineering degree could end up in your position though. (Maybe I'm ignorant...)
Now's a great time to do your MSc because you can weather the economic storm in academia and pray that the job market will be better when you're out. Heck, you might even get funding so it won't be as much of a financial burden. ...
But that said - What degree do you have that left you stuck on the frontlines of an IT helpdesk? If you don't have a BSc, speak now... (Formal education IS a go
Black holes in a Bathtub by E. Berti (2005):

The argument basically goes that when you unplug your bathtub, there's a certain point at which waves generated past the "event horizon" near the hole never escape the hole. It's an interesting read, but I was under the impression that this is basically the same thing, albeit not an effect that arises from quantum field theory.
It's about protecting your users, and protecting your project.
Take a large, reputable open source project like Audacity. If some scammer comes along and bundles their own version of Audacity with some spyware and tries to distribute it under the Audacity name, this is damaging to both users and the reputation of the software. Audacity's defense against people like this is their trademark. Nobody will confuse real "Audacity" with any ripoff, because nobody else can use the name.
This also protects the developers, who have worked hard to produce great software, and who deserve to have it recognized as something special on their resumes/CVs. Preserving the reputation (ie. name) of your software project helps ensure their contributions to the project aren't devalued.
Lastly, the Mozilla example in the article can easily be countered by the infamous OpenSSL/Debian fiasco, where a Debian packager incorrectly patched OpenSSL and created a vulnerability. This was certainly damaging for OpenSSL's reputation, even though it wasn't their fault. If Ubuntu decides to patch Firefox and introduces bugs, it's Firefox (NOT Ubuntu) who looks bad to users. IMO this is good justification for exercising ownership of your trademark.
... unless you believe all the hyperbole that comes out of Apple's marketing department.
The iPhone is a gaming platform as much as my Tamagotchi is a gaming platform (when compared to a DS). We're talking casual, short games vs. full blown DS games, there's no comparison here.
Nintendo's online game store is probably going to be a precursor to a full-blown AAA-title download store for them. They're not interested in making the DS into a PDA, they're interested in cutting out Walmart as a middle-man.
(You don't have to look very far to see how digital distribution is changing the gaming market. Eg. XBox Live Arcade, Steam, D2D, etc. Nintendo wants a piece of the sweet sweet pie that Valve cooked with Steam.)
The lowest order state of the vortex has 4 modes because:
A) The demagnetizing field wants to minimize free magnetic poles at the surface of the element. This might be the largest contribution to the vorticity (ie. having all the spins aligned in a vortex minimizes the free poles at the surface).
B) There is a discontinuity at the center of the vortex when you look at in-plane magnetization. The spins at the center are frustrated and are forced out-of-plane.
What do you mean by "folds" on the vortex? Are you talking about impurities that would pin the field?
Don't confuse out-of-plane magnetization ("perpendicular storage") with bubble memory, they are not the same thing. (There's a reason one came much later than the other. I'd like to give you a better explanation than this, but I don't have a good reference handy. Can anyone dig something up?)
The sizes involved are indeed different, see [1] where the diameter of their elements is 700 nm, and contrast with [2] (bubble memory) where a 2x2um cell was used. Perhaps with larger circular elements you won't have a single-domain state (ie. no vortex).
... and please don't misunderstand me, I don't mean to start a flamewar. I wouldn't mind having a definitive answer to these questions too. If you can dig up any relevant papers or sources, I'd be interested to take a look at them. Thanks!
This sounds a lot like magnetic bubble memory that intel, fujitsu, IMB and TI made in the 1980s.
That too had multiple states per "bubble". However the higher-order bubbles were generally not used. The reason was, it was hard enough keeping the single bit (zeroth order mode) bubbles stable at high circulation and high density.
Since here the domains are fixed and the disk moves it might be easier to use higher order magnetic domain modes.
Magnetic vortices are significantly smaller than the bubbles in bubble memory. Because of this, there are no "higher order" states - you have 4 distinct magnetization states (CW/CCW, in/out), and there are no in-between states.
The trick is figuring out how to get the switching speed down using exchange bias coupling and crazy anisotropy effects.
