Sorry but Microsoft isn't running down to the corner store for fuel, heck neither is my little S&P 500 company. We have trucks deliver fuel a tanker full at a time. With all my generators going full bore I'm burning over 100 gallons an hour, hardly something you can deliver via gas can =)
Yep, weekly is a great schedule, and as I posted upthread we only found out that our generators weren't properly winter specced due to a weekly test, a monthly test might have missed it if it had happened on a couple of warm days during the year.
Yep, the weekly maintenance cycle is how we found out the idiots hadn't specified oil or battery heaters for our backup generators, MUCH better to find out due to a weekly test than to find out when a blizzard takes out power.
Who only tests their generator "every couple months"? Ours exercise weekly and have quarterly PM's from Caterpillar (none of our datacenter generators are Cat's but they were already doing the work for the building generators and it's not like their diesel mechanics know any less than anyone elses).
The answer to that kind of problem is Win7 XP mode, basically it runs XP in a VM and you can tell it to only expose one app or the whole environment. With a modern laptop with 8GB+ of ram it runs well unless you do something stupid like put AV in the XP mode and have both environments running scheduled scans.
Hehe, my smartphone does everything a PC can do and more. I run Debian chroot on top of Android so I have access to the entire Android catalog and the entire Debian catalog (well, ok X doesn't work very well yet, so the CLI catalog but that will be fixed eventually). With a dual core 1.5Ghz processor and a gig of ram and a decent GPU I have more power than a laptop from just 5 years ago. All that and it fits in a shirt pocket. Now tell me why that doesn't seem like progress.
You've got the argument backwards, the OP said he was told never to use a business asset for personal use, if it's a business asset then of course it can be seized for actions against the corporation. I would agree to not use personal assets for business purposes unless you're willing to lose them (though I wonder how that works if you declare a portion of your personal residence as an office, they obviously can't seize your entire house to cover the corporate debt, perhaps it's just like the situation with a landlord, you're essentially leasing the space to the corporation so it's not an asset).
Uh, Google showed an AFR of over 10% for the SATA disks in their study with a high duty cycle, that's compared to 1.5-2% for enterprise drives that typically run flat out for their entire life. Also the Google study made no conclusions wrt sas vs sata, however the numbers MS released showed "enterprise" SATA with a 5% AFR and MDL SAS with a 2.75% AFR. SATA drives also have a much worse BER than enterprise drives.
The computer one seems funny to me, as an example with corporate cars there's a standard personal use line for payroll taxes (including for an S-corp), I'd assume you'd just have to declare that a certain percentage of the PC use was personal and pay payroll taxes on that fraction of the depreciation schedule.
Well, as far as achievable computation, that's why Linkpack reports Rmax and Rpeak, however the one big area where Linpack is lacking as a measurement stick for many real workloads is its small communications overhead, it's much easier to achieve high utilization on Linpack then it is for many other workloads.
Ah, another esoteric, nearly impossible to program for architecture that flies for some problem sets but is nearly unapproachable for the non-CS science folks. I mean it's great that such things exist I guess, and in theory they can have great FLOPS/watt figures, but I wonder how much science will really get accomplished per dollar spent compared to something where standard code just runs?
I wonder why it's got such little memory? You can easily run 64GB per socket at full speed with the E5-2600 (16GB x 4 channels) without spending that much money. Heck for maybe 10% more you can run 128GB per socket (You need RDIMM's to run two 16GB modules per bank). They're apparently only running one 16GB DIMM per socket (any other configuration would be slower on the E5) which IMHO is crazy as you're going to have a hard time keeping 8 cores busy with such a small amount.
Dude, you can still buy any Dell, HP, or IBM raid controller ever produced because they sell each model by the millions. The last time I had to match firmware versions was like 8 years ago with an IBM controller, it's never been an issue with HP (there may be potential issues between uncertified controller and disk firmware combinations but they're a hell of a lot less likely than similar problems with "let's buy a bunch of generic HDD's and pray they all play nicely with whatever controller I bought"). If you consider data reliability an optional feature (or like the disk performance of drives with their write cache disabled) then you don't belong anywhere near anything called a server.
That particular problem was solved a few years ago when they introduced flash backed write cache. Basically it's a supercap or bank of regular caps that will power the controller long enough to push ram contents into a flash module. I won't buy anything else and in fact HP stopped offering battery backed units with the gen8 servers.
your RAID controller dies: good luck getting the data off the disks This is such BS! The RAID controllers from the big three have placed redundant copies of the metadata on the drives for at least a decade. All you need to recover the array in the event of a card failure is to place them into another server with the same generation controller or replace the failed controller. Heck when HP designed their own hardware you could even move an array out of a Proliant and place it in an MSA array and the array would read the metadata and recognize the RAID configuration.
Not in the least bit, Google designs their servers to optimize power usage and absolute lowest cost per compute cycle. Those are not the same goals for every server buyer. For instance single threaded performance is a large factor for me because we run a lot of interactive workloads that are single threaded or weakly threaded but Google doesn't really care about single threaded performance because they're optimizing at the datacenter level. I also care a lot more about the reliability of any given unit because my jobs are mostly traditional single-server jobs with only my most critical workloads being clustered so the loss of any given node has a significant impact on my overall reliability whereas Google can lose dozens of servers a day per datacenter and it would have no impact on their overall operations. Another example is storage, Google uses COTS SATA drives with horrible MTBF stats and they do so without RAID protection, the only application where that might remotely have a chance of working for me is Exchange 2010 because I have four copies of each database online and the client is seamlessly pointed to a working copy.
Yep, we have a significant slope between two parking lots on our HQ campus, the entire connector between the two is heated from below with hot water heating. Sure enough when the slop goes from ~5% to essentially flat there's a drain to take the water away (I believe it goes to our catch pond).
They don't have to. ETSI is the main standards body for GSM related technology including LTE and As ETSI states in its Guide on Intellectual Property Rights: “Specific licensing terms and negotiations are commercial issues between the companies and shall not be addressed within ETSI.”
IE unlike most standards bodies ETSI does not mandate FRAND terms, only disclosure.
Most routine flights could be flown gate to gate by autopilot, it's for the.00001% that you pay the pilot (like when a flock of geese take out both engines and you have to dead stick it into the Hudson).
USGS quad maps, whenever I go into the back country I have them printed on heavy cotton stock and waterproofed. I also have my GPS but I don't want to die just because the screen or board cracked. When I'm traveling to a new city I either print out an overview map or I have a travel guide with me. I also print two copies of my boarding pass, one for my person and one for my bag, I've misplaced the one on my person on a couple occasions and all I had to do was pull the spare out of my laptop bag.
That's why the Kindle HD is offering parental controls =) In fact it's why I'm seriously considering one for the kids over the Nexus 7, if they make it as easy to implement as the XBOX-360 does then it's a killer feature. I'll of course root it and install the Google Play store for my user, but the kids can have a nice PG-13 experience with game timers.

I was taking loufoque's comment literally that you were architecturally limited to 128MB per thread which would be fairly difficult to code for.

You don't need an identical card, just one of the same generation, at least for servers from the big 3.

There are now gloves that you can use with a capacitive touch screen. Heck there's even conductive thread you can buy to modify existing gloves.
