Yes, pretty, because each new pixel added brings the human race more knowledge about the rest of the universe. But we need to put telescopes farther from Earth, such as above and below the elliptic plane of the solar system and far enough away so that the parallax is better than we get with that of the earth's orbit. Being further away from the Sun would also lower the temperature and noise floor, bringing increased sensitivity.
There's something seriously wrong with Canada if their Parliament considers their proceedings to be proprietary. The Canadian voters have paid for them, and if Parliament is trying to hide their proceedings then there's some secret they're trying to hide.
Sometimes, when the US has completely disgusted me, I merely have to look north for some tomfoolery that makes me remember again why I never moved up there.
It's too early to even guess what the smashing of this old model will mean, in terms of disproving or proving Global Warming. Don't jump the gun. I think it's significant, but it may not actually end up as a significant factor is widely accepted theories about global warming. Let's let the experts digest this data before making any grand pronouncements.
Yeah, just makes sure you can get out cleanly when things go to hell. Not if, but when. They always do. Make sure that you are well protected from non-compete agreements - after all, your marketable expertise is in this very field. The laws regarding non-competes vary a lot from state to state, so see what state law will be governing the contract. I'd also be very careful about accepting any deal that was complicated and involved your ownership of company stock - too often these can be extremely restricted, based upon rules against insider trading. Also, make sure that what you sell to the megacorp isn't open-ended, but rather, it restricted to the things disclosed. They may try to tempt you with larger money in exchange for concessions that put you at risk, but remember that there are some companies which will lure you into such an agreement to stay for a certain number of years in order to gain your full payment, but then go about making it impossible for you to do, hence you default and the leave you with nothing. It's better to set a very loose and amenable to you contract, and then bargain from a point of power towards other work. What I mean is, get the sale agreement very simple leaving you carefree, and consulting agreements worked out separately - so if you tell them to go screw on a consulting job you don't lose anything regarding the sale. Also, I am prejudiced towards cash, and not stock, when selling out. Just because lots of companies can crash the value of your holdings in the conglomerate at will.
Shostak fails to consider that antimatter is a practical fuel. Right now, the processes we have to make it are sadly inefficient, but this doesn't matter much, because we have lots of energy - yes, it's called the Sun, good 'ol Sol, and if antimatter factories were produced en masse and positioned in a close orbit of the sun, the energy available is great (Never mind the fact that the sun creates antimatter itself - we don't know how to get any of that, currently). Antimatter is so ultimately powerful a fuel that a spacecraft visiting these orbital antimatter factories, using antimatter as fuel for the return journey, would have lots left after the journey for other uses.
In addition, there is the feasability of gravity assisted acceleration. This is the process whereby a small body gains velocity from the rotational energy of the large body by means of a carefully calculated 'flyby' trajectory. This is what the star-crossed (no pun intended) Apollo 13 mission used to return to earth, and it has been used to plan 'The Interplanetary Network' of such trajectories, changing angle at LaGrange points of various bodies. It turns out that the effect is multiplied by an addition of energy at perigee, such as that which could be provided by antimatter engines.
I really don't have the time or room to spell it all out here, you'll just have to wait until my books come out.
There is also evidence against global warming, and reputable scientists that oppose the idea. While each piece of evidence needs to be exposed, those which seem to weaken a theory need to be paid particular attention.
Now, if you are complaining that Slashdot seems to be a bit sensationalist, I might agree.
I guess I've been in the Boston area too long. I was wondering why there was Ice in the subway station, and why I hadn't seen it. OoPs! But the Davis stop on the subway does have XKCD in it.
My fix is on the server side. It does not require changes in the stack code of clients who would connect to it. Reverse-engineering it would gain the attackers nothing. An all-or-nothing fix would not be much of a fix. Neither would one which was successful based upon its obscurity.
I am not telling you what it is because I am hoping that Microsoft will pay me some money to give them access to it. Apple as well (and Sun if they're still around). Once these are secured, I will open the invention to the FOSOSs. (Free Open Source Operating Systems). Call me greedy if you want, but I am tired of researching security and not getting paid for my hard work. That's why you haven't seen me by this handle or my real name posting security advisories for some time.
Source address level filtering does provide some level of protection against a SYN flood. The problem is, it is not universally implemented. Another problem is someone who doesn't care to hide their address. If you are doing more than a SYN flood, but more advanced TCP hijinx, you need to use your read IP address anyhow. So, it's not much of a fix. Neither is the recommendations which came out back in 2000, which was to increase the resource limits that the operating system imposed upon the IP stack. I could go on and on, on how each measure so far implemented has just raised the bar against these type of attacks, but hasn't really done much to prevent them. Yes, you might not be able to knock over a stock OpenBSD install with 1023 packets any more, but the problem persists.
This problem was demonstrated in 2000, with the NAPTHA software and its demonstration that the problem is not academic. Yes, before NAPTHA, there was some software that could demonstrate the issue but this software had issues itself (written in perl, kept state) which limited its effectiveness. SockStress is just NAPTHA revisited.
I have a fix for this problem, but there's not enough room in the margin to describe it.
While lots of the things you say have a ring of truth to them, I think your suggestion is a horrible one. It's too simple. I know people in their nineties who are intellectually fine, want to live, but their bones are fragile. You would say that these people don't get a broken hip mended? no way! But if you were to ask if they wanted a heart transplant, they'd probably turn it down, saying it's their time to go and there's younger people who need a chance to grow old. It's not about the surgery, it's about the cost, and not just the simple cost - about the emotional cost to them and those around them, about the opportunity cost to others. Now people that are brain dead, or dying of everything all at once, at some point there needs to be a decision to give up. But who makes that decision? I wouldn't put it in your hands, after what you've said.
Medical ethics is hard. That's why you need bastards like Doctor Gregory House.
I used to get ear infections regularly. My ear canal would swell up and close, and i'd be in pain and hard of hearing. I haven't had them in a while until now. I found that antibiotics did LOTS of good. But so did anti-inflammatory drugs like Naproxen Sodium. I am going to the doc tomorrow to get some antibiotics.
The Americans had a real problem, and pretty much the British owed the seas during the war. Which is why, it was a big deal when Lafayette and French forces showed up. Maybe their cannons weren't as good as the English, but they were still a formidable foe.
Americans should remember that Lafayette and the French forces were a real game changer in the American Revolution. We should remember this especially when others talk about WW2, saying that the US saved France from the Germans and they're ungrateful.
Yes and no. If you can't do a good job machining, you're better off with bronze, which is easier to machine and also isn't as sensitive to changes in temperature. But if you can machine, you're better off with iron, or steel is even better, because they're a lot stronger. The machine, you need machine tools with a harder metal edge. So if you are going to machine iron, you need steel. If you're going to going to machine steel, you need a harder steel. Just like that.
The metallurgy isn't that simple. Steel requires a small amount of carbon, but over around 2% and you've got cast iron, not steel. Cast iron is brittle. This wasn't understood back in the Elizabethan age. They simply knew that iron from some sources was better than others, and this happened because of the natural variation in carbon content. For instance, Swedish iron was considered the best.
WHat would be better is a simple wall wart, would be something with a 3.5" SATA drive interface and two slots or so for everyday memory. Something you can use generic parts in. Yeah, I think that would be useful also if it could have a USB 2.0 interface for a printserver. Hell, I'd pay for than $100.
Now that I think of it, I really don't want one. Why pay $300 for a crippled device? I'd rather pay a little more and get something with a real keyboard, and real extendability. I think such a thing at $100 would be nice, but that's not going to happen. Or, a device that had amazing battery life, such as a week of use, but that's not going to happen either. The OLPC XO looks like a much better product, that's something I might actually use, if the keyboard was larger.
Remember that: if you use it for amateur radio purposes, you only are able to use a few channels, you can't use any encryption, and you can't use it for commercial purposes. Those ad-blockers are going to be pretty important, because that's a commercial use - even if you don't initiate the connection to the ad's web server by your own means, you're still responsible for it's content. But my view is a pretty narrow one which is often ignored. If you call the FCC on someone though, you're going to need to make sure you're not breaking a ton of laws when accusing someone else.
It's easier to stop creating problems than it is to avoid troublemakers. Tragedy of the commons? perhaps. But, if you were to get your ham radio license and transmit at maximum permissible power using ham modes on 2.4 ghz, you could jam the whole neighborhood. Note that doing this intentionally would be illegal.
So, to co-exist harmoniously, what everyone needs to do is this:
1) Filter the broadcasts that Microsoft operating systems are making over the next. They make a lot of noise, and the leaking of such information could be considered a security risk.
2) Turn off your SSID beacon, or set it to broadcast infrequently. Perhaps once per second. Beacons are sent at the lowest data rate, see below.
3) Not quite sure how to accomplish this with everyday routers, but most of the time you don't want to be connected at less than 11 mbps, so why even accept 1 mbps connections? Sure, the signal goes farther, but at a reduced efficiency - which means, it takes longer to send the same amount of data, which means that the band is more congested.
4) There are long and short preambles, sometimes these are settable. But I am going out on a limb here, I can't remember much about the preambles, but shorter would be better.
I know this is 'you should' information, and not a really concise 'how-to', which is what you and your neighbors need. But you're asking for free advice, so maybe you can do some in-depth research and find out how to implement the above methods. Remember, your neighbors are probably suffering too. If you can get everyone in the area to run a router with openwrt on it, then you'll have access to all the settings you'll need to minimize interference.
This is why me and some others are forming research lab co-ops on the outskirts of university centers. Whatever we can do off-campus, we do. There will be chapters or associates or whatever starting up around the world, but first lab will be in Albany, NY, aimed at SUNY Albany, Union, and RPI students. We'd like to get ones started in other areas like Cambridge/Boston but the cost of even the most raw floor space is expensive. If you're interested in one in your area, reply to this thread.
Yes, I just got a wonderful new computer for under $200. It's got 216 cores. But they're all pretty small. It's called an Nvidia GTX 260 core 216. It's also a graphics card.
Which is all very nice until I look around and see that there's not all that much that's been done to optimize tasks for parallel execution, with the exception of graphics. But that's changing, and programmers need to realize this is where performance is going to come from in the future.
It's funny, though, sitting here running three virtual machines on my desktop on two cores (AMD) and how wonderful it would be if these could utilize the parallelism inherent in virtual machines. I am not expecting that vmware is going to be able to offer me the ability to run 216 instances of linux on my video card, but perhaps in the future some paradigm refinement will allow allocation of cores to problems which will take different courses towards parallelisation, either by creating virtual machines (very restricted and inefficient, but secure and easy) or by having more lightweight structures where the task is simple and repetitive and performance is important. Or even better, know when NOT to use the full GPU. How about knowing when to shut down certain cores, and use the freed resources of heat sink and power to dynamically increase the clock speed of the remaining cores..in such a way then, optimizing the tasks and the hardware both.
Well if this rambles a bit I am sorry. I am sorta thinking 'out loud'. Maybe I just need to get a blog and not subject slashdot readers to my madness.
There is a rainforest in Patagonia. It's a temperate, as opposed to tropical, rainforest. Patagonia is a large area, and diverse, varying from near (ant)arctic to almost warm.
Not all rain forests are 'tropical'. Sections of Chile, along with the Pacific Northwest of North America, Japan, New Zealand, and parts of China are 'temperate' rain forests.
