Oh, I understand. It's just that most existing IT infrastructure is 120/240V or 208V, if you're doing a greenfield full on datacenter design 277V probably makes sense because you're potentially buying enough equipment to get rates close to the market rate for 100-240V auto-ranging power supplies and you can specify what your PDU design will be. But if you're like 90% of the market you either have standard service off a utility panel in shared space or an existing datacenter with UPS's and PDU's specified for the more traditional voltages. As an example I would have a hard time switching because my A side UPS is setup to go into multiple 240V busways from Starline and my B side UPS goes into panels that feed 240V L21 whips. Changing either over to a 480/277 setup would be quite capital intensive even if done at UPS replacement time, far beyond what a couple percent efficiency improvement could save. On the bright side for me we're going to reduce our power use by ~6.5kw next week when we shut off the servers for our old ERP environment, moving everything but the database to VM's was a real win all around =)
What war in Libya? We've basically done some live bombing practice and sent in a handful of trainers and some covert troops. We expended more resources arresting Noriega.
Not sure how practical a PSU optimized for 277V input is for general use and the 450W max power is a bit tight for some Nehalem based configurations but overall it's pretty cool. The cold side containment, open frame cases, air side economizer, higher set points are now pretty standard design consideration. The airflow and fan optimizations were very cool but I'm not sure how applicable they are to most datacenters with a variable demand (I imagine FB runs their servers at a constant workload with only enough unused capacity to account for other datacenter outages).
Huh, they've agreed to $30 of the $33B with the complete defunding of a few organizations being unacceptable, the teaparty then tried to get the goal moved to $60B and Boehner "compromised" on $40B with additional program defundings and the original defundings still in place.
Sort of off topic but I couldn't believe the Republican proposed budget, let's shift profits to private insurance company, shift cost to the poor and retired, and reduce the marginal tax rate on the top 1% to 25%, the lowest level since 1931 which coincidentally failed to bring us out of the great depression and did nothing to spur job growth.
Actually Gates just said any shutdown will mean half the pay will be lost on the next paycheck and a delay of longer than a few days will mean no paycheck. They will most likely be paid with a makeup check at some point (I believe they always have) but for people living paycheck to paycheck (basically everyone below an E5 and most enlisted people) it will be a significant impact.
There are alternatives to most of that, most of the plastics can be replaced with bi-plastics as can the foam. Synthetic lubricants are generally superior but are more expensive. Roads can be made from concrete (again more expensive, today). I'm not sure about the window tint but thin film bio-plastics are possible.
My concern would be with failure mode, if the electronics in a variable viscosity system give out you still have a hydraulic shock, when this thing goes you instantly have a failed suspension system which would be "not good" if you were in the middle of a high speed turn.
A) Unless they are the sole copyright holders (not feasible for any decent scale project unless you ask for assignment of copyright like the FSF does) then they can't change the license.
B) It's generally understood that the GPL is non-revocable for that existing codebase and any forks but AFAIK that assumption has never been tested in court because sole rights holders are so rare for anything that matters.
Well, the LZW patent did expire just before GIF's became fairly outmoded so it IS possible for a patent to expire while the idea is still useful, it's just rare =)
Because copyright can only cover a specific implementation but patents can now cover an idea in such a way that there is no alternative way to implement it. Not only that but all copyleft open source licenses actually rely on copyrights in order to make the mandates of the license enforceable.
I would expect a lot of innovation out of this deal. No, not from the stupidly large mega-company, but rather from all the fabless startup companies that will be founded by all the good engineers that TI lays off.
Balding IS trivial, the only difference it's caused me is now I need to wear a wool cap during the winter where before I preferred a hood so as not to mess with my long hair =)
It's mostly because you are buying $50 motherboards that you aren't getting BIOS updates to support future chips, there's no profit margin in $50 parts to support developing and testing an upgraded BIOS for an old product.
I've done it on the server side, upgrading from quad core to hex core Xeon's (5500 to 5600) and from Barcelona to Shanghai. When you have thousands (or tens of thousands) of dollars worth of DIMM's, lots of peripherals like HBA's, and the time invested in setting up and QA'ing an application environment the small amount of cash to upgrade performance can often be well worth it.
While AMD's sockets have been pin compatible since socket AM2 there have definitely been incompatibilities between chipsets, BIOS's, chips, and ram along the way. The matrix of what's compatible with what is probably too big to fit onto even a B sized plotter sheet. This sounds like much the same thing where you can drop an AM3+ part into an AM3 socket with reduced performance. The only reason I can see doing that would be if you want more performance in a given power envelope as the new chips will give you much better MIPS/Watt.
I think the difference was those who took AP Calc AB and tested out do poorly but those who took BC and tested into Calc II in college generally did ok from what I observed. Not that I'm a great one to judge, I had to take Calc four times before I found someone who could teach it in a way I could understand (not a math person!) but then I got all the way through diff eq.
Yeah, I can still remember seeing one flying overhead one day. I had no idea what it was, just that it was an incredibly beautiful plane with the engines in the rear. I looked it up and have been a huge fan ever since.
Thanks for all the great designs over the years. You made the prettiest commercial plane ever the Beechcraft Starship and got us closer to commercial spaceships than anyone else. Enjoy your well deserved retirement, I wish they made more like you =)
Sounds more like BD quality, 300GB/20(episodes in a typical season)=15GB/episode or roughly BD quality. Now, since these were post production and just intended for final edit that's pretty normal.

Google only reveals a design they are about to retire from what I've gathered, their current and N-1 designs are never discussed as far as I can tell.
Ymodem-G baby. If your connection didn't suck it allowed substantially better throughput than even zmodem =)

I doubt the fixed magnets are going to be big enough to provide much dampening, despite what the press release says.
I'm assuming they spidered the IPv4 address space looking for SSL connections and downloaded any certs they found.

This is incorrect, background apps have worked on the ipad since iOS 4.2 and on the iphone/touch since 4.0.
