It seems like a sweet way to get "public" pictures if you were in the paparazzi / picture media biz. People are talking about loading it down a load of weapons, but I say, just load it up with extra batteries to get more flight time, and a good camera, and I imagine you'd do quite well following (or doing recon on) anyone.
We just need more data to tease out the statistics in: Psychohistory. Now, is that a good thing?
Asimov on psychohistory
"Well, I can't help but think it would be good, except that in my stories, I always have opposing views. In other words, people argue all possible... all possible... ways of looking at psychohistory and deciding whether it is good or bad. So you can't really tell. I happen to feel sort of on the optimistic side. I think if we can somehow get across some of the problems that face us now, humanity has a glorious future, and that if we could use the tenets of psychohistory to guide ourselves we might avoid a great many troubles. But on the other hand, it might create troubles. It's impossible to tell in advance."

I tend to agree with him. In the end, the information is out there, and someone is going to put it together. To what ends remains to be see.
One of the places I worked at provided shared web hosting. It was pretty normal for a single server to have ~300 accounts on them, and generally the servers would purr along without any issues. Customers who were constantly eating up more than their share of resources would get silently migrated over to what we called the swamp servers. That way all the customers who were resource hogs but to cheap to go with a VPS/dedicated server/colo solution could use as much resources as they wanted with other abusive users. This was ~12 years ago.
My woefully lacking formal education in this area might be showing as well, but let me try to answer:
1. My understanding is the event horizon is a mind boggling bad place to be near. Even if the spaghettification of your cube didn't take place, light is falling into the black hole, so you'd not be able to read anything in it.
2. As best we can tell, only Hawking radiation is capable of escaping a black hole. Any information would be lost due to entropy, you'd not be able to retrieve any specific information out of that radiation.
3. Why do you hate the #3?
4. Black holes do grow bigger as they continue to merge with the matter that is falling into them. There have been speculations in the past that they could be linked to a white hole, but so far we have no direct evidence of them, just lots of beautiful math.
I will admit to not having much knowledge about the history of our pursuit of prime numbers, but I'm at a loss about the page you linked to. I understand where 1 could be considered a prime, but that list also includes numbers 4, 10, 12, 14, etc on that same list of primes. What school of thought would consider those prime? I'm genuinely curious, because I feel like I must be missing something obvious.
i go way back to the Riva TNT2 and voodoo2 days. i bought a top of the line voodoo2 the day it came out back in 1998. cost me $299. these days a top of the line card is $500 or more and it sucks enough electricity to power a small town.
x-box 360 cost me $299 same as my PS3. i can also use each one to watch media on my tv without the hassle of doing it on the PC which is usually in the opposite side of the house or room. the games are usually the same which means that the gameplay experience is the same. most people won't spend the money just for the graphics card. the "gamer" is now a 40 year old person that plays Cityville on facebook. not a nerd playing Doom, command and conquer or starcraft on their PC
That is because you are still thinking you need to have the flagship product from whatever graphics card company. You can do better than just get by with an Radeon 5570, the model I bought is even fanless, and doesn't require any extra power connectors like those damn 6-pin molex power ports that older PSU's don't support! some cards even want 2 of them! and yet it still runs most games for me at 1920x1080 with most everything turned up. You can get this card for ~$70. It ran the Valve Source SDK Base 2007 benchmark with everything maxed was 122 fps (on a rather low end AMD Phenom II X2 555 3.2ghz cpu).
Bleh... I accidentally said (not in 2011) for A Dance with Dragons, didn't mean to say not in... still, the rest of the timeline is correct and saddening. George R R Martin needs to take some notes from Elizabeth Moon. Book 2 of the new series already came out, book 3 is done and at the editor. Book 4 has been started. And still no Song of Ice and Fire. He really should have finished it in October of last year so it could hit stands the same time and the TV series starts in April. So much for that. The new Deeds of Paks series is really good so far. Elizabeth Moons writing has improved 10 fold since she last visited the series. And it went from a 3 book series to 5 books I think at this point. The woman is a machine... story gets into her head and she cannot stop writing.
Was anyone actually worried he would "pull a Jordan?"
Yeah, their is concern... check out this timeline:
* A Game of Thrones (1996)
* A Clash of Kings (1998) 2 years
* A Storm of Swords (2000) 2 years
* A Feast for Crows (2005) 5 years and next book half done
* A Dance with Dragons (not in 2011) 6 years
* The Winds of Winter (forthcoming) so 6 years (GRRM age now 68+)
* A Dream of Spring (forthcoming) so 6 years (GRRM 75+)
Unless something really changes in the speed of his writing we are likely never going to read the ending.
The servers look a lot like some of the 1U and 2U SuperMicro's I've worked with. In your standard 42U rack you could fit ~80 servers in each of these racks, with 2U left over for network/etc. The pictures all show a pretty large datacenter floor that is mostly empty, maybe they don't have the cooling and power in place to really load the racks up to full density? Agreed though, their layout seems odd.
...such as the difference between a tropical storm or a hurricane.
Sorry, but this isn't so.
Tropical Storm = Distinct rotary circulation, constant wind speed ranges 39-73 miles per hour (34-63 knots).
Hurricane = Pronounced rotary circulation, constant wind speed of 74 miles per hours (64 knots) or more.
I'm guessing you don't live in an area that regularly gets hit by these storms, as I really though this was common knowledge. Nothing arbitrary about it, unless we are using different definitions of arbitrary. Source: NOAA.
I know that this authentication feature was implemented due in part to the government scale phishing scheme in Tunisia, however I've been thinking perhaps it is also a clever way to weed out all of the duplicate accounts people use to play those games on FB that give you some modicum of extra... stuff, for the number of "friends" you have. I broke free from the time vampire that is FB games over a year ago, so I'm not sure if it is still an issue. However at the time it wasn't that hard to script your way to a few thousand friends, which now would almost guarantee that I would quickly get locked out of the account because I didn't really know anyone on my "friends" list.
Still, it is going to take him forever to pay off his likely expensive tuition on that salary. However it would make a great 2nd job to have on the side.
No matter what, you want at least 2 copies (although 3 is what I'm doing). My suggestion I use:
1) If you don't have enough disk space, and you cannot upgrade the internal drive, get a USB IDE drive to put these files on.
2) Find a friend/family member who will let you rsync to and come to some agreement where you give them a hard drive you'll use as a place to backup to. On the drive you give them, rsync your files to it first so you have a copy so the first rsync doesn't take a ton of time and bandwidth. From their, you can setup a scheduled event tailored to whatever is most reasonable to both of you (i.e. throttle the bandwidth to make it less of a strain on the connection; stop and resume the rsync during specific hours/days, etc) If you are concerned with them accessing your files, install truecrypt, make a virtual encypted disk, put your files in it, and call it a day. None of this requires much in the way of advanced computer knowledge and could be able to be worked out in a day of light pursuit and some luck finding someone friendly to answer any questions;-)
3) Find another friend/family member, make them another copy of your files to keep. This can be in whatever is the most cost/time effective method you are comfortable with. I just buy any plain SATA drive that matched my needs and go with that, generally I go for something at least 2 or 3 times the size of my data at the time, to allow for some growth. Then, swing by there house once or twice a year to do an update, or maybe after any significant picture shooting extravaganza/vacation.
The key is not having your eggs all in the same basket. You'll always have a complete and current copy at home, you'll have a second copy that is a week to a month behind being rsync'd, and you'll have a third copy getting updated once or twice a year on a drive sitting in someones drawer. Works great for me, and is pretty cheap for the redundancy.
Completely agreed. Sorry for speaking in generalities (likely even incorrect generalities)... not in my proper sorts today. Still, the network IO bottleneck is the same problem for everyone, and an expensive one at that. Cheers.
The machines named Jaguar and Franklin are Cray's running Lustre.
The apostrophe is never used to form a plural. Not ever. No, not even then.
In terms of scalability, from the Wikipedia page for the Jaguar system at Oak Ridge National Labs (a large Cray XT5), their Lustre filesystem is 10 petabytes with read/write performance of approximately 240GB/sec (not sure what benchmark was used to get that number).
OK, so I'm not surprised if someone gets good performance from a Cray, but can't Lustre be used with lots of commodity hardware instead? I thought that was knid of the point.
I don't think a lot of people are going to go into many details on this article, because anyone using luster is liking using it in some way to leverage the idea of the cloud inside their respective business'es. Yes, I think it would scale well with commodity hardware, however their is no getting around the need of a fast interconnect between all nodes. If you cannot afford at least 10GbE for your entire storage cluster, don't even bother with luster, you'll hit a bottleneck on network IO likely with just a few boxes. Anyone who is serious about it is going to go with an Infiniband solution as it scales almost indefinitely due to its non blocking nature. So getting any performance out of lustre isn't going to be done on the cheap.
If they can't see the runway, it doesn't matter what is painted on it.
The lateral error is going to be far more significant than the angular error in any case.
If they can be told how to find the end of the runway, they can be told how to line up on it regardless of its name.
Think of the repainting as a very low tech way to avoid confusion possibly for both the ATC and the pilot. Having the name of the runway be the same as the orientation of the heading of the aircraft 'might' be enough to help in some instances with runway approach that it justifies the cost. That, and it likely annoyed the crap out of some earlier significant pilot(s) who, much like grammar Nazi's, want to make sure everything is correct and had it codified into some airport flight safety standard.
I agree with you. As a former ISP employee, it is pretty well known that the FBI has electronic taps into most ISP companies. I assume the same would be true for datacenter operations as well. I have to imagine watching the traffic silently would have yielded more info than shutting down servers and taking them in for review. No need to worry about masking keys when you can watch the raw traffic come in and see who the major actors are.
But more than that, why raid a datacenter? Why not work with the datacenter to get what they need and minimize an outage for any other custemers. It is like the FBI treats datacenters and ISP's as bad actors and doesn't trust that they aren't in on the crime which I think is rather outrageous.
Considering their motive is indirect censorship and their target market that they wish would not see the offending material is amongst the veritable hordes of Facebook/Twitter/MySpace zombies out there this is incredibly stupid.
URL shortener exist for a reason. It makes posting to Facebook and Twitter that much easier. Not to mention, it would be pretty hard for BoFA to prevent people from forming Facebook groups.
Domain names are just one of the ways we use to communicate locations, and find them, on the Internet now.
Foolish and a waste of money.
Foolish and a waste of money to most people. However to a multi-billion $ empire, spending a few bills on a couple of domain names is nothing if it stops even a handful of people from stumbling onto something that they think would harm their image. This is risk prevention/avoidance at a very low cost. That said, I completely agree with you.
Hi, I'm not up for going to deep on this one, but here is the/. article that says the FBI has these kinds of toys. You might have to dig hard to find the phone make/model... not sure.
I'm remembering when 3 of my 5 IBM Deskstar's took a crap. Out of all the drives to choose for my first at home RAID 5, I accidentally bought the Titanic.
All the same, if they are serious about security of their data, not allowing any writable / removable media on there facility just makes sense. On top of that, they should weld the cases on all of the workstations shut, disable pretty much all IO ports except for a physically permanent connection for the keyboard, mouse, monitor, and network cable. Monitoring to see if any new writable media becomes available on the workstation would be a good next place to flag for further investigation.

Honestly, if you keep an extra (or even use your current) computer case, PSU, DVD-ROM, and HDD, you can build out a better / faster gaming computer for under $299.
