Handy for things like uranium isotope separation, and also for creating things like Bosenovas. The problem is, that the process is very sensitive to the frequency of the laser. If these guys have found a way to reliably, inexpensively create the right frequency of light to cool anything...then that substance can act as a heat sink to cool other substance. This could open a whole exciting new era of science and technology. But I won't hold my breathe, the proof is in the pudding, etc.
The fact that it has a high specific impulse is good, if one were traveling though very empty space. But, the gravitational slingshots and interplanetary highways require short bursts of high energy, at very specific times, rather than high efficiency.
Still, though, the problem which neither of these addresses, and that none of the solutions I have seen so far address, is the collision with other masses.
Some sort of cloud has seeped in through his left ear and is now between his brain and his senses. He's always fascinated by the next shiny object, I am so glad I dumped Ubuntu last year and went back to Debian. Yeah, I know I am going to get downmoderated for saying this, but I have grown new respect for a distribution that just stays the course, year after year, doing what they do best and not trying to emulate Microsoft, Apple, or Google. I like my keyboard just fine, thank you. I like having control over my data and my programs, right on my own computer, and not on someone else's where their incompetence or greed causes me grief at some indeterminate point in the future. The computer IS more than the Internet. Behold discrete data stores, cherish them, and they can be truly yours.
I am so tired of runtime failure. I am tired of feeling that which has been labeled as 'shipped code' was always shipped too early, and that there's some embarrassing bug that's going to come back and bite me(us) on the ass. Perhaps programming in Ada would allow me to sleep well at night, knowing that I didn't prematurely ship code. Sure, there's still the problems of fundamental logic errors based upon the programmer(s) misunderstanding the problem, but knowing that we're clever idiots is better than being an idiotic idiot.
I keep on seeing security fails, such as recent one(s) in Android, makes me wary. I trust my old 5 lb desk phone, not the sleek gadget which has the misnomer 'smartphone'. I'd like to have code that is as solid and reliable as my old 5 lb desk phone.
I can understand why it was done. The source tree needs to be cleaned out so it is easier to maintain. But, Linux has always had this 'no platform left behind' mantra, for better or for worse. I liked the idea that a 386 microcontroller would never been orphaned by an open source project. But that time has passed, and now it really is time for Linux to fork - I am sure that there re some people out there that do want to keep the 386 support alive, and the good thing is that they CAN fork it, because it is open source. So, in the end, it's just a sad fact that some weeding has to be done, for the good of the herd, but all of those processors being put out to pasture can continue, just in a different herd.
I know that Germany has a horribly low birth rate, which is already causing problems. In Europe, Ireland is relatively high, though lower than it used to be. It would be interesting to predict the long-term social situation caused by large portions of the population being outside of the workforce. A country with a 2.1-2.4 children per couple, stable over a long time, is going to be a stable, happy country.
To be honest, there's a time an place for homemade equipment, and this isn't it. You've admitted this isn't your area of expertise. Neither is it your parents'. If it breaks, what are you going to do? The idea of using a a Pringle's can is absurd. Get a strong, professionally built antenna and mount.
Some things to think about: the higher gain of a highly directional antenna comes from focusing the energy more tightly than a lower-gain directional antenna. The more directional an antenna is, the more precision and accuracy must be used in aiming it. It will also, presumable, but outside in the elements, with wind, rain, snow, animals, and sunlight. All of these can degrade the antenna or interfere with its aiming. Therefore, a very strong mount must be used when using a high-gain antenna.
My suggestion is to go to your parents' house well prepared, with antennas of differing gain. Use the one with the lowest gain which gives a moderately strong signal. For instance, if 5 bars means the strongest possible signal, use the antenna that gets your 4 bars. The antenna which gives you 5 bars is most likely providing unneeded signal strength, at the cost of requiring better aiming. This doesn't mean you should use the antenna that provides one or two bars, however, because the extra signal strength might be needed during strong rain or snow. you should also go prepared with a proper knowledge of antenna installation, including lighting protection and grounding, use of a drip loop, know the signal loss of the cable you are using, etc. You should already have calculated the path loss from the cell site to your parents' house, and know the receive sensitivity and transmit power of the cell site and the 4G device for your parents' house. You can then figure out if this is in the realm of possibility. When you go to do the installation on site, bring spares, the proper tools, some general tools, gloves, clothing appropriate to the task, safety gear, and make sure that you have health insurance coverage.
It's easy to do a bad job of antenna installation. Sometimes you get lucky, and it will be sufficient -for a while. But then it will fail and you're up a creek without a paddle. Spend the money and do it right, or hire a professional to do it. These are your parents, after all, you don't want to disappoint them.
So you've got Seattle on one hand, and Massachusetts on the other. Massachusetts has a reputation of being more theoretical about engineering, as opposed to cheap and practical like west-coast people. Massachusetts-made thinks like DEC's VAX were big, expensive, heavy, tough, and polished. Seattle has...well...MSDOS. Quick, dirty, gets the job done, ultimately Microsoft flourished and DEC withered and died. BUT concepts live on, as NT was done by ex-DEC people. West Coast is more hack, East Coast is more engineering. Personally, I am from Massachusetts and would like to think the Yankee 'craftsman' approach is better than the west-coast hippie 'hack', but the truth is, that the distinction isn't always easily made, and that elegant design needs some pragmatism as well. But, I think it's an interesting intellectual exercise when think of East Coast CS craftsmen vs. West Coast CE hackers.
If you look at my handle here on slashdot, you'll see I've been a fan for years. it was my online handle in the 80s, and I took the identity seriously. I haven't seen much of the new series. And now...from what I've read...I don't want to. I am afraid I might have to hurt someone badly if they destroy my idea of what Doctor Who is. Perhaps it's time to end this blasphemy now, and save our souls from the eternal fire.
- yes, I believe it is a very important task to start to measure these over the long term. We don't yet have the technology to get to these places. The data gathered now will still be useful in a couple of hundred years when we can actually launch missions to other star systems.
This isn't really such fresh news. And, I already fixed it for you: simply take shorter warp jumps, so not as much energy builds up. You're welcome. Patent pending.
....if it isn't already. Don't we have laws against such discrimination? Oh wait, they call it "Affirmative Action", wave a wand over it, and the governing rules of logic are magically overridden.
In spite of what is being reported in the media, there were no lines. However, I didn't get an ' I voted' pin:(. The election machines were rinky-dink. paper? How primitive!
Not true, there's plenty of old US military airfields. Hanscom, near Boston, would be a perfect second airport for the city, but the problem is that NIMBYs shut it down, they said it was because of noise. I guess the civilian airliners don't make enough noise, because those military jets sure make an awful racket.
RyanAir just sucks...I mean, it is so horrible, it shouldn't even be allowed to fly. Lufthansa is great, and I'd spend $100 to fly them over Air France. But not $500, which was the difference, last time I checked.
The problem with transatlantic flights is that there is no rational system set up to transport efficiently. I thought of one, floated the idea, and was roundly ignored. Oh well. I'll just join the mob of cynical people and find someone else to charge my flights to (business expense).
I was using this stuff in 1995-96. I might still have the floppys (!) or CDs around for pentium architcture. I'll look around, it's probably in storage. But you know it's full of security holes, right?
I've worked in many datacenters over the years. I want to follow up on my previous posts, where I recommend discrete, reliable legacy boxes for NTP and DNS. I want to make it clear that I don't think you should just pick up any old spare box, throw an OS on it, and be done in half an hour. That may work at home or in your hackshack, but in a professional environment, it isn't good enough. These services are part of the foundation upon which the datacenter is built. If the foundation is weak, no structure built on it will have a long life. These services and the machines that provide them are noticeable only in their absence, when all hell is breaking loose. Running a good datacenter requires proactive maintenance and planning. Just because things are running smoothly is no excuse for the operator to play endless games of solitaire waiting for a drive to fail so he can hot-swap it. Everything needs to be planned, documented, updated, and monitored. consumer-grade hardware just won't make the grade in critical infrastructure. Sure, that old PC MAY last twenty years, but that is not good enough. In a major data center, downtime is lost money, often lots of money. Spend money now to save later. Oh, I know, politicians these days want to cut down infrastructure spending so they can lower taxes and balance the budget deficit, but type of thinking leads to rash decisions that are penny-wise and pound-foolish.
Think of a fire station. Those guys just don't sit around playing cards, waiting for the next fire. They spend time at the station making sure their equipment is clean, in good shape, and exactly where it needs to be so when the call does come, they can perform. Run the datacenter in a similar way.

Funny! But Bacteria is a noun, and as such is always capitalized in German. Never mind the fact that the word is 'Bakerie'. Good try, though!
I'll be interested to see if it can be replicated in a scientific community where fraud isn't so rampant.
Another Earth-ending apocalypse avoided! I am so disappointed.

At first I thought I had wandered into Psychiatry Today, but then I realized that no, I was still on Slashdot. What is this story doing here?

the jobs are gone and never coming back. IBM = Indian Business Machines.
I also means that IBM code quality will be low, as programmers are paid by the kb in India.

John F. Kennedy was assassinated decades before the iPad was created. I sense a hoax!
Because it means that the US hasn't cornered the market on stupidity, or even the market slice of telling lies in school textbooks.
This isn't really such fresh news. And, I already fixed it for you: simply take shorter warp jumps, so not as much energy builds up. You're welcome. Patent pending.
In North Korea this wouldn't be an issue, because they don't have other races.

It was walking on the blade of a knife, and then slipped.
Maybe not the sharpest knife in the drawer.
Seppu-ku requires sharp blades.
