Rearrange your server room so that the bottom-most servers from each cabinet are moved into the open space. Then you won't lose as much hardware when your data center floods due to global warming.
A lot of people seem to be replying to this as if the parent were suggesting client side caching. More likely, the parent is talking about ISP level cache servers, which Netflix provides ISPs free of charge. This drastically reduces the amount of bandwidth being used between the ISP and the Internet. Netflix has actually done a great job with their cache servers, open source hardware design, based loosely on the Backblaze storage pod. Netflix also publishes the exact hardware they use to build them. Very cool move for a big corporation. https://www.netflix.com/openco...
Usually if a gasoline tank is punctured, the fuel would just leak out, and not catch on fire. If its diesel, its much more unlikely to catch fire. The best way to deal with a battery fire is to eject it. This has been done historically on some aircraft with NiCad batteries. The batteries are kept in an isolated bay and is held in by fusible links. If the battery goes into a thermal runaway, it will drop out of the bottom of the plane and become somebody else's problem. Tesla could implement a modular battery design, with a grid of shields to allow the same functionality. Perhaps they will do this in the future.
I flew for the airlines up until 2005, well before the tablets in the cockpit.
None of the airlines are replacing critical paper copies with an electronic version. Historically, there would be three copies of all the manuals and charts, one for the captain, one for the first officer, and one for the airplane.
The iPads replace the 40 pounds of paper that each pilot used to be required to carry.
The aviaion industry is probably the most cautious and slow moving industry out there (in response to the poster who brought up decades-old technology in the cockpit). Pilots welcome the new technology -- it usually makes their jobs easier, but it must pass an unbelievable amount of scrutiny (over the course of many many years) before it can actually completely replace an older, but proven tech.
Plenty of old engines can get a supplemental type certificate (STC) to run on motor gas. The problem is that gasoline is hard to find these days. In Massachusetts, there is not a single service station, on or off airport that sells gasoline. They all sell gasohol, which is gasoline with 10% ethanol (or in rare cases MTBE) added. Every STC that I've seen specifically excludes fuel with alchohol additives. One reason being alcohol's affinity for water. You need to be able to separate out the water from the fuel and you can't do it if alchol is present. At high altitudes (cold temperatures), water, or hydrous ethanol can become slushy, clogging fuel lines and filters. Needless to say, that's very bad. Cubs and Ercoupes probably can run on motor gas (without alcohol), because they do not have high performance / high compression engines, and were never restricted to at least 100 octane fuel.
Access is still provided via the API. Just because they got rid of a button in their GUI doesn't mean they are denying you access. They are probably just trying to clean up their interface by removing extra features that no one uses.
The solution is for Dell to get all that bloatware working in wine and install it! While they are at it, they can root the kernel/filesystem so that it is impossible to delete.
Next step, install a small cron job that fiddles with/sys/devices/system/cpu/cpuN/cpufreq/ so that the speed steps down slowly over time. Now they have recreated the Dell/Windows experience that their customers know and love.
Not really. People are using GIFs for animation. PNGs don't support that. Many browsers don't support APNGs. Regular PNGs didn't even work correctly in IE6, which took way too long to die.
People at most income levels are directly "bothered" by the price of gas. Think of the CEO trying to justify $20k spent on a private jet flight to a board of directors, when only a few years ago, the same flight would have only cost $10k.
Not to mention the fact that our entire economy is very closely tied to the price of fuel, so even the folks who only own bicycles are touched by rising fuel costs.
I thought of the mosquito killing laser gun years before they did.
I'm sure the reason they are not actually selling it, is that it occasionally sets nearby trees on fire when it misses a shot. My version won't start fires, but I'd be crazy to try to bring it to market knowing that the product would be in I.V.'s sights from the get go.
A space elevator can't just go to LEO, it's got to go all the way to geosynchronous orbit (42,000 kilometers up) and then past that for a counterweight.
If we only had to go to LEO, we'd probably have done it already.
Also, there are a ton of satellites in LEO, and most of them are likely to hit the tether at some point. It is just a matter of time (and not as much time as you'd think -- you'd probably have a near miss every couple weeks).
The airlines to hire people to keep the airplane's copy of all the charts up to date, but in almost every airline, the pilots are responsible for doing the updates on their own set, and everyone needs their own set. Every time a new update comes out, every pilot gets an envelope with a hundred or more loose leaf pages, and they have to locate the old copy of each in their chart book, tear out the old one, and insert the new one into the rings. It is really annoying and takes a long time.
Time spent preparing charts is not counted as duty time, so often times, pilots who have been busy or who have procrastinated will be up late the night before a trip updating all the approach plates so that they are legal to fly the next day.
With electronic flight bags, the airline still keeps paper copies in the cockpit, but the pilots use their electronic copies, and the updates involve touching an update button. With the Jeppessen product, all the specific company and aircraft specific manuals are also linked to your account, so if any procedures change, those are also updated within the app. It is very cool. Pilots should focus on flying, not collating. This is a huge step forward.
If your inner ear can distinguish the difference between a uniform field, aka an accelerating spaceship, and the curved field of a point source 6300000 meters away, I'll eat my hat.
I agree that the spinning case would probably feel a little wierd to most people. That's why I only suggested the first case as being indistinguishable.
Of course you could devise an experiment to tell the difference between the first case and earth, but the parent of the thread is talking about artificial gravity!!! I guarantee you I could devise an experiment to prove that the gravitation field inside of the starship entriprise or battlestar galactica does not have an identical curviture to that of the earth.
The point of having artificial gravity is not to decieve instruments, it's to keep those instruments from floating away from their labs!
artificial gravity is easy. Just keep the ship accellerating forward, or spinning around a convenient axis. The former case, of the accellerating frame should be indistiguishable from being in a uniform gravitational field.
I'm not affiliated with Supermicro in any way, but they have four 1U serverboards designed for the 12 core opterons, so that's 48 cores in a 1U server. I'm guessing that Supermicro is not the only vendor of quad opteron boards supporting the latest chips. There are most likely quite a few of these in use by real people. Anyone want to speak up?
I know from personal experience that the socket F opterons performed very poorly in an 8 way configuration compared to the previous generation (socket 940 gen). I ran multiple tests on dual core chips (885s, I think), back in 2006 or 7 where I'd get nearly double the performance in going from a quad configuration to an 8 way configuration, but with the socket F breed of chips, there was no performance boost at all, it was like the clock speed was being cut in half and all the threads took twice as long to complete. I saw this behavior again and again, and the motherboard manufacturer that I was testing the chips with told me that it was an issue with the chips themselves. I think this is the reason why 8-way opteron systems are very rare now.
This is a blatant misquote by the media. Prince was merely saying that IPv4 is over. Prince recently dropped all IPv4 support in his home network, and is excited to be making the switch from unhealthy decimal "numbers" (actually he said "octets") to long 128bit hexadecimal strings. WTF is wrong with the media.
I mean, if 2.4Ghz has all these laws protecting us against observation, how about some laws that cover 660Thz. I want to be able to project information in blue and know that it's illegal for others to look at it.
