I'm in a PhD program and plan to stay in academic research after I graduate even though I could have made far more in industry, though you're right, there are many folks who will do whatever pays the most. I like Obama's idea of having a new common mission that kids can latch on to - that combined with increased investment in alternative fuels, a new generation can make an impact on this important issue, all the while training new scientists and engineers.
I found this answer by Obama on the connection between education and technology.
The first half of Obama's comments are the usual talk we hear from all the democratic candidates - that no child left behind is a failure, etc.
The last minute and half of the answer, however, is very interesting - Obama presented a great new idea (and I've heard pretty much every idea that every candidate throws out there on most issues, but I had never heard this) that ties together two important campaign issues: energy independence and education. More than that, I think there might be two parts to his point, one subtle and one obvious.
The first part is that we need kids to go into science and engineering, and energy independence is a good motivator. The second, subtle part is that if we have a president who can once again inspire the youth like JFK, we'll be twice as effective in the first part - and truly will be able to create a movement around energy independence that will probably spread to other needed economic arenas.
I agree that Ron Paul has the only sensible foreign policy of the Republican candidates, but a presidential candidate must be evaluated on other criteria as well.
Finally! Someone who gets it! Bolo was pretty much the best game I have ever played. Sure, newer games have flash and other things, but I was talking to some folks recently about why they like Super Smash Bros and the answer was 'the depth' of the game. Well, that's what Bolo had: simplicity yet depth, strategy yet action, and most of all, balance.
Some folks at ETH Zurich took it one step further, and wrote a client - BitThief - that doesn't upload and yet still can download as fast as a regular client. This is especially valuable in countries that define copyright violation to be the uploading of content.
Oh...I'm in grad school, and while I don't think the professors really like it, they don't mind in the end as long as work gets done. I think the same is probably true in other more progressive tech workplaces. If not...you could always put the Bailey's in a Hazelnut-flavored non-dairy creamer bottle or something.
I know this is offtopic, but the post itself highlights the fact that one of those involved here is from MIT. What difference does it make? For a community of people like those that read slashdot---those that appreciate things that are outside of the mainstream and shun brand loyalty---it's strange that many worship MIT. While they do good work over there, their school brand is unbelievably overhyped.
(This post does not stem from bitterness; I got into MIT but turned them down to go elsewhere. Many other schools have research programs that are as strong or stronger, but without the overhyped brand.)
I have a major problem starting projects, but I've found a trick that gets the job done: alcohol.
Now you may be thinking that that's exactly what you shouldn't have if you want to get anything done, but it works, applied correctly. The key is having between 1-2 drinks and combining that with some coffee. The alcohol gets you to stop fretting over what needs to be done and gets you to dive right into work, and the coffee gets you to stay awake and somewhat focused.
I used to keep a bottle of Bailey's or Kahlua on my desk at work just to add to my coffee.
While secret sharing is cool, one of its primary drawbacks is that it's usually built using asymmetric crypto (as in, based on number theoretic assumptions and the like). That means it's potentially quite slow. Ross Anderson wrote a paper on a cool alternative which uses only symmetric primitives to achieve the same result. (In fact, he's able to build a lot of different things by combining symmetric primitives in the right way.)
You're missing out on possibly the most amazing undergraduate and graduate crypto classes out there. His research and course notes (which are almost book-like) have become a standard in the community. (And other schools, such as Berkeley and Maryland, use his course notes for their crypto classes.)
I know this is slightly off topic, but I'm wondering what happened to my favorite indie game of all time: Bolo. What ever happened to it?
There was a clone called Winbolo that some guy wrote, but it doesn't work properly in linux and doesn't seem to be under development. If only there were an open source version of it, we could revive it.
It's amazing how long this little game has endured, largely due to the balance of its arcade and strategic bits. It's also proof that a lot can be done with some 4 -bit graphics and lo-fi sound.
NIST did a great job with the AES competition (to develop and standardize a new block cipher to replace the aging DES) - why don't they have a competition to standardize a electronic voting machine platform? There's no reason this shouldn't be done on a national basis.
I think that if we as a community put enough pressure on NIST, they'll do it. And since NIST is a non-partisan body, there's no good reason for congress to not support a design that is sponsored by NIST.
Such a process would promote both openness of participation and review of designs. The winning design could then be standardized and vendors could simply implement them to spec.
Sure, but that's a perfect business opportunity: every computer could come preloaded with every movie and album you'd ever possibly want, encrypted. To play, you'd need to buy the key.
This is an idea that's been toyed with by a few people, but it seems tough. They've outlined an approach using some standard peer-to-peer systems - see this paper for a list of the challenges and some numbers. Unfortunately, without some sort of sacrifices in search quality (or number of documents), it's probably not feasible yet, at least by their figures.
Even better than prioritizing ACKs...

It's possible to play various tricks as a TCP receiver to get a server to send you data as fast as you want. Instead of just prioritizing ACKs, if you split ACKs, send duplicate ACKs, or send ACKs for data you haven't gotten yet, the server will think the connection is great and increase the send window. The details are here.
There's also research (some of which I'm working on) that tries to address payment schemes in ad hoc networks as you suggest.
The premise is that hosts will behave in a greedy, "self-interested" fashion in a game-theoretic sense. One main difficulty is in creating a distributed virtual-currency system without a centralized authority. Several approaches either use a centralized authority or require secure hardware at each node.
There are a lot of reasons why this is both a good and bad thing.
NASA is quite deserving of funding in my opinion - it is one of the few government supported research institutions left, and its funding has been decreasing year after year, so any extra money it can gather will be beneficial.
However, a bad side to this is that NASA may become more commercial in its aims. Projects that make more money might gain priority instead of pure research projects that cost money. The research done on the space shuttle may become more market and commercially driven instead of scientifically driven.
You can just use icecast to do this. This is actually what they're going to use - I just talked with them, and they should have an icecast broadcast going soon.
His example was that (although I don't know if it is true) is that in Bogota, since there is a very clearly defined economic class divide, the poor are using email to send randsom notes to the rich requesting money for the return of the rich they kidnap. He said there are even services that will do this.

Consider his highly questionable comments about blacks.
I believe he's good mainly as a way of injecting sense about foreign policy into the Republican debates.

Or you could use nooks. Nooks will protect the OS from driver crashes and restart failed drivers transparently.

I don't know if you noticed, but he has a history of breaking, oh, WinZip, Diebold voting machines, and SSH.

I don't think most users really care about the epidemiological issues and -- they care about not being hacked, which is very doable.
Looks like they're taking care of stopping worm outbreaks practically as well.
Sure, but that's a perfect business opportunity: every computer could come preloaded with every movie and album you'd ever possibly want, encrypted. To play, you'd need to buy the key.
Might I note that this is the same Yoshi Kohno who broke the Diebold voting system and SSH.
I Agree. This is very important, because unless this makes national news, California will be the only state dumping Diebold.
I would give you mod points if I had any.

There have been several research efforts to ensure security and prevent misbehavior in ad hoc networks.
The following papers address many of the issues:
The Ariadne System (for secure routing)
Mitigating routing misbehavior
There are several others that solve similar problems in the research literature.
