Fuel Cells and Proton Exchange Membranes often use Platinum or Palladium as a catalyst - which is very expensive. Bloom's box uses something cheaper. The science/tech is used in a lot of places you might not expect, like submarines too. It can be the most efficient way to generate and process hydrogen as well. For example, if you put enough solar panels/wind turbines to power the United States - you would invest so much in power lines, and so much would be lost in transmission, that it's not economic. Fuel cells can generate hydrogen from water at the point of generation - I believe more efficiently than electrolysis. Then the hydrogen could be transported similarly to CNG. Then Hydrogen can be "burned" or run the other direction through the Fuel Cell.

The politics and economics are becoming more favorable. Glad to see coverage on Mashable.
The claim is "interesting " insofar as it is astoundingly unlikely, and almost certainly untrue.

The chemistry of solid oxide fuel cells are well understood. It only works one way. They don't produce hydrogen when you feed them voltage. It's like spinning the flywheel on a car engine backwards, and expecting gasoline to pour back into the fuel tank.
This concept of "if we get the quorum, then it's on, but if not, no one pays" is also known as "an assurance contract".

I agree with the commenters saying that this is not the right way to solve things. If you want more entrepeneurial talents, get the money out of the States, not the people in.
Why not make that an affinity/loyalty marketing program, call it "The Club @DoD" or whatever. Have members join this program for a lifetime $100 membership, which gives them $200 in drink vouchers out of the box good for a year (or put it on the Club Debit card, or whatever) and then once that is used up, they can continue using the card for 20% off drink purchases for life.

If some of the lushes go through that 200 dollars in credit, who cares, anything else they buy is gravy (albeit at 20% discount, but that's easily well past bar profit margins per glass. If it isn't, maybe he needs to find another line of business.

Don't limit it to the first 500 either, keep it as a permanent fixture.
no, you're absolutely incorrect.

if you create 5 US jobs, you get to stay.

if you don't create 5 US jobs, but can generate EITHER $1M in revenue (at break-even or better), OR raise $1M in additional capital from ANY qualifying investor (doesn't have to be the original one), you get to stay.

please read the language carefully -- it does cover the situation adequately.

we did take quite a bit of time to consider the exact language, and worked hard to get it to be functional.
who fucking cares?
That's a great idea. I think there is a future for this model. I have lots of ideas where it would be profitable and beneficial with way lower risk than through many traditional mechanisms.
If you don't have the time for that, try node.js - it handles all the epoll/kqueue for you, letting you program in high-level asynchronous javascript.
2 Ways to Sync Google Buzz with Twitter
Something like the HTTP digest authentication but non-standard, right?

I think it's still possible to have the server accept the token as a URL parameter if it's in some special debug mode. Obviously the debug mode should be implemented with great caution.

Or challenges/digests can be sent back and forth as part of data rather than in the headers. This way I can debug the REST server using HTML forms.
The reason we need universities to be better funded, though, is moral. Fewer than 50% of all people who start a 4 year degree every complete it.

I'm not sure I see the moral case for subsidizing people who try college but fail to complete it. Could you explain?

In an effort to cut costs universities are increasingly using adjunct labor. I believe that most people who teach in higher education are not tenured.

Why is this bad? Lower cost labor means that the taxpayers and students get more bang for their buck.
perhaps a laudable goal, however:

In case you were wondering about the name, SHODAN was the evil computer from the classic computer games System Shock and System Shock 2. (Apparently the name stood for "Sentient Hyper-Optimized Data Access Network," a delightful string of marketing jargon!)

What I really like about Hacker News is that it's overwhelmingly made up people cleverly disagreeing - so that plants/idiots/jokers are generally more obvious.
I found it interesting, for one. Teaches something about narrowly missed opportunities and their long-run effects.
Perhaps I should ask you then, why would you take this visa deal instead of simply having the investors give you the money for you to create your business in your home country?

Yeah, I'm going to spend this on Bourbon anyways :) Might as well taste a few before buying something new.
I certainly can't understand what is gained by bringing the entrepreneurs to a market already saturated with too many competitors? If you need more entrepreneurs from abroad, they can do as much from their own countries as from the US. And once their companies grow they could easily open an office in the States, allowing them to travel easily on a simple work visa.

WHY should non-US entrepreneurs need to come to the States to start businesses? Just because the US VC's are too lazy to take their money overseas?

I wonder how it reacts with Fluoride Divanadium, also known as FDiV.
We're taking a slightly different angle, in that the individual customers each have a better experience with the product when it's done together.

What you're mentioning, in terms of pooling resources toward getting a product developed, is also a really neat application. But it adds another layer of uncertainty (i.e. can the developer actually deliver on what's being promised?), so we're starting out with a product that exists and already extremely well-received by its target audience, and applying the model there. If we can prove that consumers understand the model for an already-existing product, then we (or others) can push into the not-yet-developed product area.
Excellent -- ~3k is a price that makes me happy, 800k not so much. Let's hope as they move out prototyping to the assembly line they're able to achieve the economies of scale they're looking for.
That's just complete bullcrap. One of the reasons the DMCA exists in the US is to protect companies like Google in exactly this type of situation. Many EU countries have similar laws
And celibate.
Done! Supporting bourbon is good, supporting Chicago small business is better, and supporting both at the same time AND GETTING BOURBON? A moral imperative!
haha, sounded like 800k was the price for the huge box (the kind ebay is running) and $3000 is the price of one big enough to run your home.

There are no restrictions on the kinds of jobs created? In other words, it's acceptable to create 5 minimum wage jobs?

I'm not saying that's a problem, but it certainly makes the requirement easier to satisfy. A full time minimum wage job including taxes is just about $20k a year.
Real-World Concurrency
It depends on the type of small business -- how it is incorporated. And yes I agree small businesses have it hard because of regulations and taxation, but I'm in favor of lowering all taxes.

But to claim that capital gains are the same as income is incredibly misleading. In the special case where you are a small business owner that works at the business then yes you are taxed as an employee. The money you invested will be recouped just as venture capital would -- when the company is sold or by paying dividends.
I've never had to do that (ever), but...

aditya: dude, if you can't create at least 5 jobs in 2 years with $250K in capital, you're a pretty pathetic excuse for an entrepreneur.

this is not a handout, it's a hand up. we expect people to innovate, create jobs, and create positive economic results.

we're trying to help those who are willing to help themselves. and yes, those entrepreneurs who are more capable -- that is, can run a business profitably at some scale, and can create a minimum # of jobs -- will have a better shot than others.

there is nothing unfair or unethical about trying to help those entrepreneurs who are willing to do the work necessary to make it happen.

Werner Vogels: Oracle's Private 'Cloud' Not a Cloud At All
My experience on OS X:

First, Firefox takes a long time to start up, probably between 5 and 10 seconds. Tabs open and close quickly, but there's a constantly noticable 1/2-1 second delay when opening a new window. ⌘-N ... short pause ... window opens. With both Chrome and Safari it's instantaneous.

But perhaps most importantly, Chrome runs everything in separate processes and when you close a tab, that memory is freed up. This is a huge deal compared to both Firefox and Safari. It means you can just leave Chrome open forever, whereas Firefox and Safari will just gradually eat up more and more RAM. If RAM usage from other processes pushes Firefox's memory to disk, then it's even worse, since you then need to wait forever to do anything with the browser while it pulls it from disk. Safari is similar, but not as bad since it's more responsive overall. While with Chrome all you'd need to do is close a couple tabs, with Firefox you have restart the whole app.

And I experience all of this on a Firefox accounts with zero extensions.

There really is no contest. If you aren't seeing a difference I can only presume it's because of your usage patterns or possibly the platform, although I'm skeptical of the latter since people widely report Firefox hogging memory on every platform.

How did Scrooge do any work? Bashful purchased the ingredients, assembled them, packed the product and delivered it. Scrooge did NOTHING. Scrooge could have been in a coma and it would not affect production. Are you claiming coma victims are capable of work? Scrooge could have been dead during production! Are you claiming dead people are capable of work?!

If you can't distinguish labor from capital then you should not be commenting on economic articles.

Is the 2 $50k investment's cumulative? In other words, someone like pg makes a lot of small investments. He is obviously included in the kinds of investors you're trying to select with this bill, but would he meet this requirement?

I think it should say at least 2 investments, and at least $100k in total value of the investments.
This isn't meant as a general-purpose immigration option, and there's no reason to expect it will appeal to everyone (it's not supposed to). It covers a small corner case that is not covered by existing legislation, and it's separate from the larger issue of immigration reform.

What you propose is an easier solution for prospective immigrants, but much more difficult politically.
Unless you have a peering relationship with a backbone provider, someone is responsible in a safe-harbor sense for any content you put on the internet. Period. That's what the parent post meant in saying that elimination of safe harbour would favor the big players over the small, and the internet would cease to exist as we know it.

This fact is indifferent to whether you use web-rings, NNTP, your own "personal website," or YouTube to post content.
For me, the pain of ochem really depended on the instructor. Where I went to college, it really felt like 90% of the ochem instructors were either bad teachers or liked to watch students struggle. It was otherwise pretty easy material--if you had a good teacher.

From the shear number of horror stories about ochem and my own experience, I'd say most ochem professors are just bad teachers and don't care about their students.
Grinding some numbers:

The data sheet says 661000 btu/hr of fuel to run at 100kw. 100kwh is 341,230 btu, so it looks like about 50% efficiency from shipped hyrdocarbon source to electricity on site. Very good.

On the american house using 1kw, that is obviously not a peak. At 8 cents/kwh, a 1kw average use house has a $57/mo electric bill. Looking at my bills I can only presume they counted a lot of small apartments and homeless people in cardboard boxes in the average.
The circular slider is a pretty specific user element. Maybe so specific that it doesn't belong in a general purpose framework, I don't know. But it definitely has its place. It's usually coupled with a text field for precision, but it's generally a good tool for setting an angle in a UI.
I was ridiculously excited to see this in my inbox this morning!

Optimizing for revenue collection is designing the rules to be easily broken. This does not enhance safety.

If you want to bust a lot of speeders by a school, you must first have a lot of people speeding by a school. The best way to do this is to have a nice, straight, uncontrolled road that's clearly safe to drive at a faster speed than posted. That will encourage speeding and thus ticket revenue when you set up a speed trap.

If you are more concerned about the safety of children crossing the road, you will do things to discourage people from actually driving fast. You'd make the road curvy, make T-intersections 3-way stops, put in speed bumps, add crossing guards, or use whatever combination of a variety of techniques makes sense for that road in order to make drivers go slower.

> Does Cassandra actually support transactions?

He means in the sense that databases have typically been divided into "transaction processing" (doing a small set of operations over and over with large concurrency) and "analytics" (doing potentially monstrous ad-hoc queries w/ very low concurrency).

> You could easily have this in a distributed system that has a single master (implemented as a distributed state machine), without all the disadvantages of a gossip-protocol.

Sure, but then you have all the disadvantages of a single master system. :)

For most systems the single master system and its potential for catastrophic downtime if failover goes badly (which it _always_ does eventually; if you claim otherwise you are a novice or selling snake oil) is the worse choice.

> a P2P system will in most cases be slower than a hierarchical one.

I call BS. An O(1) routing p2p system like Cassandra has no inherent speed disadvantage over a heirarchical system.

Case in point: Cassandra is substantially faster than HBase, its closest heirarchical competitor. There's also Hypertable, but to a first approximation nobody uses it so I don't know of any benchmarks.
Is there a way for a business to get themselves delisted from Yelp (either manually or in a robots.txt automated way)?
It's a lot easy to pull people over on wide and open roads, though. If you were designing a traffic area around an elementary school for maximum safety, you'd narrow the streets and do a lot of things that probably get in the way of setting up speed traps--especially the easily concealed speed traps cops are so fond of.

WHY should non-US entrepreneurs need to come to the States to start businesses?

From the perspective of the US, that should be obvious: because the new jobs would be created in the US rather than the entrepreneur's home country.

From the entrepreneur's perspective, that's a much better question, and the answer will vary from case to case.

To feel safe, secure and taken care of, girls are now turning to men with brains. These women see a direct correlation between brains and dollah-dollah bills y’all and geeks have brains for days.

It's a weak correlation; there are plenty of poor geniuses. Displays of wealth probably work better than displays of smarts.

I think social justice is more about equality of individual justice as applied to people in different classes. I guess that's how I'd answer that.

So OSHA requires protections for low-"class" workers that rich people would do if they were doing the work... something along those lines.

Related side note: the researcher that coined the term alpha male recently redefined it.

According to him, the alpha male that typically comes to mind is a misconception as alpha wolves aren't alpha wolves through some violent usurpation. Rather, they become alpha males in much the same way that a human Dad does. As the oldest and provider for the familiy, he is the natural leader.
In my short life (in miami), I've experienced the following:

Young women (18-24) seem to be trending towards males with influence of some sort & a sense of humor - so if you're "well connected" but not well off, "chicks can dig that" or if you're "well known" (where people stop you on the street) & of course, if you're rich or appear to be rich.

I suppose all of them could require brains, but not all of them do.
