2a) Personally, I figure two 30 amp circuits per network rack, each on a different circuit. (run two PDU's, one into the wall, one into a UPS. (with a max draw of 30 amps per rack). That number becomes very, very useful for planning how much AC you would need for a room at full capacity.
10) you said CNC equipment. if you have something that throws MASSIVE electrical interference, either put it as far from the cable runs as possible, or run fiber, with a remote punch down panel and mini rack.
I ride, and always hated the "loud Pipes save lives" saying.. Unless you bend the pipes completely around to face forward, they aren't easily heard by people in front of you.
My rural ISP has always done this.. Its a royal pain in the ass. My CPE device is 192.168.100.62, on the WAN side. Makes VOIP, hosting your own video game server on a console, bittorrent, and a dozen other things very, very much a pain in the butt. I gave up with an IPSec VPN, and use an SSL one now, but its not the same.. its client based, instead of a hardware one I wanted for my home office.
Ubiquity (a major maker of wireless ISP equipment and backhaul) still doesn't support IPv6 very well at all on the brand new devices they are selling to ISP's.. And my arguments about setting up 6rd or something similar fell on ears that responded the same as the GPP (but, IPv4 is all you need to reach everything)...
We have had 4 companies we connected to with VPN's over the last two years. All 4 of them were medical industry companies with > 2,000 employees. All four required we have our own valid, routable IP range to use before they would connect with us.
if you have connections to other networks, and/or vpn's, internal network IP's are a pain in the ass. How do you setup a VPN when both ends are using 192.168.1.x? easy, you overload NAT, so both sides see the other as a completely different subnet. Do that about 5 times, and then try to debug some firewall rules.. Many larger companies will now refuse to setup VPN's with companies that use reserved addresses, since its such a pain in the rear.
By using a valid IP address, your assuring that they are globally unique.
The whole point of openstack is to be agnostic to the software that provides the service. You can run KVM, Xen, a full citrix XenServer, and a few other pieces of virtualization software on the nodes. Why should they care, as long as VMWare provides the correct API's, which vendor or tool is running it?
I had to do a study at a former employer that was buying 5,000 laptops, and wanted to know if the extra Million or Two was worth it for the Intel SSD's in our thinkpad's.. The short answer, hell yes.. The "faster" ones were even worth it over the slower Samsung drives. (at the time of the T400, about 1/3 the speed, but still much faster than disk)
Did all sorts of boot testing.. and to the actual definition of "started" both the 5400 rpm, 7200rpm, and SSD drives were about the same speed. But none of our users cared about how fast it got to the login prompt. They didn't consider the computer "up" until outlook was open (with many > 2GB OST files), chat program was open, excel, web browser, AV, and TWO monitoring programs (different departments trying to figure out why things were slow.) . this testing got really, really interesting. The no seek time, and massive random IO meant that we went from about 10 Minutes for some users to be completely usable, to under 1:51 seconds. The boot graphs (See http://blogs.msdn.com/b/pigscanfly/ for some great info about windows performance and graphing) were amazing with the SSD. Just a straight line maxed out. With a professional company, where the average Bill rate of its staff was something close to $100/hour the payback for the Intel SSD's was about 2 months. Once login happened, the computers were trying to start up so much crap, that the apps were fighting for disk IO with a spindle, even though we hand NCQ on the drives.
Or, if your as big as Microsoft, you setup a RAID (Redundant Array of Inexpensive Datacenters) and just figure that as long as a couple of DC's are up, your good to go...
From my experience, an LLC is used for partnerships. In some states, only certain professionals can even form LLC's. Often they are for protecting the partners from each other.. (ie, accountant partner screws up.. Lawsuit can hurt the partner, but they can't go after the assets of the other partners, if they were not involved)
Corporations are a way to shield owners (stock holders) from liability. (You can sue Bill Gates, when MS screws up, just because he's a stock-holder)
BTW, The "normal" Corporate version of Windows 7 does not include BitLocker support. You need the "extra spendy" Version.
My company was supposed to be part of a "Case Study" with Microsoft on Bitlocker, but ended up skipping it, and going with another product. Reporting and monitoring was a nightmare. The only way you could tell if it was done encrypting a drive was to look at the local pc, if I remember right. Which really sucks with a very mobile work force. Also, key recovery was possible with Active Directory, but did not work properly in things like Windows PE. I'm sure many of those have been fixed, but at the time, it was pretty basic.
Jury nullification is a constitutional doctrine which allows juries to acquit criminal defendants who are technically guilty, but who do not deserve punishment. It occurs in a trial when a jury reaches a verdict contrary to the judge's instructions as to the law.
That may be true in the consumer space, but is not anywhere close in the server space.
We specced recently a pair of Dell servers, (poweredge 810 and 815). Both with 256G of ram. Difference between the 810, with dual 6-core CPU's, and the dual AMD 16 cores? About $7500 per server. Both the CPU, and the RAM are much, much cheaper. The Ram might run slightly slower, but since were mainly using it for "buffer" space in Oracle, we don't care.. its still 1000X faster than disk. And our software doesn't need another few hundred Hz of speed per thread, we need lots and lots of threads.. Btw, that difference in price, is about the same as the cost of a Fusion-IO card for each server.. which will add much more of a performance boost to the DB and apps than a fancy processor.:)
One of the things openstack has been doing, is to abstract away the hypervisor. I believe you can manage VM's whether they are running KVM, ZEN, Amazon EC2, and vmware. Which means you can drop one, and move to the other, and still keep all your same tools to manage the machines, storage, etc, and just change or deploy new hosts. (which is big, but not as big as also re-writing all your tools for provisioning and such)
I pay for a small VMware cluster. On the download page, I can actually download all of the open source components used. Not just the client tools, but things like their data deduplication for their integrated backup. VMWare is actually a decent proponent of opens source, because its lack of licensing issues is what is making people go so crazy over virtualization. (spinning up 20 vm's to support a new project takes a few min with linux, and days with purchasing for windows;))
Of course, they are like IBM, in that the best tool to work with one of theirs, is another of theirs.. (why, why oh why do they not have a decent SNMP monitoring system? I don't want a seperate monitoring tool for my vmware servers as I do for everything else)
AHEM.. You do understand that a single source to define standards of weights and measures is kind of one of the single most KEY parts of Commerce, right? That they were established to make sure that things like "a pound" are defined, and tested and validated.
Perhaps you should read up on some of the other standards NIST has, like time. They are THE stratum 1 server for most people that use NTP. (time.gov).
Wow.. Nice. You know, not all of the other countries that have better health care than us have a huge, monolithic government agency with death panels, right? Maybe you should read up on Germany, and how they switched. Or singapore, or how health care is handled in Japan. Its not all as scary as people seem to keep trying to make Canada's system sound. (except, all my friends from Canada laugh at those comments, and say its nothing like what the politicians and people against it claim, you know.. the people that have actually been there).
Maybe you should also read a little into Amtrak while your at it. Little things, like Amtrak is not allowed to own track. At all. They cannot build or purchase their own routes. They must run secondary on most tracks, meaning they have to pull over and wait for any cargo train. (on the west coast, delays of 12 hours are more common that ontime routes) Perhaps you will also read about how the major train companies were forced to own stock in amtrak, but are not allowed to sell it, so they are stuck with it, but can't make a profit at all, so they treat it like crap. Maybe you'll also learn that EVERY SINGLE damn politician who screams about amtrak costs, gets very, very upset when they talk about closing train stations in the towns with 5,000 people in their jurisdictions.. Just look at the line from Seattle to Chicago.. there are > 40 stops. Most in towns you have never, ever heard of. Each stop adds how much time? slowing down, stopping, and then starting again? That route could be less than half the 40 hours it is now.
After that, maybe you can read about how the Postal Service has to fund 70 years of pension obligations in one decade.. Nobody else, anywhere, has 70 years of pension money sitting in an account. But it was added to a bill a few years ago, by a guy who got a TON of campaign contributions from the two companies that would benefit most to the Post office having problems. And they also pointed out that the Fed could then borrow against that money, since, even though the Post Office is supposed to be independent, they have to store this money with the Treasury. Same as amtrak, they also get very, very angry politicians when they try to close post offices in unused places.
The problem with all of these things is not that its "government" doing it, its that politicians are involved. Government runs fine in most countries, here, its actually falling apart around us, because we would rather scream about things like abortion and guns, then give people that actually understand what they are doing the tools necessary to do them.
I don't live in the woods. I live right between two towns that are 6-8 miles apart from each other. I have a MAJOR interstate (I-90) 3/4 of a mile from my house. I live 4 miles south of the exit where metro Madison, WI starts (with its 400,000 people) . I have a choice between Cell phones with 5Gb data caps, or rural wireless over 802.11b.. I currently pay $65/month for 1Mb/s. And its spotty, and full of random high latencies. Somehow, ATT manages to stretch 48,000 feet of phone line between us and the central office. ATT guy laughed, and said no equipment had been updated at our CO in over 5 years, and there was no plan to change it. My neighborhood has 50 homes, and Charter runs a fiber right down a road 1/8th a mile away, to go to a Verizon 4G tower. After I finally found someone to talk to (good luck actually finding anyone at Charter to talk to besides tech support, they don't give any info on local offices) the said they "MAY" bring cable to our neighborhood, if I could get every single house in my neighborhood to sign a thing promising to sign up for triple play for 2 years..
I have friends in similar pockets of houses in rural areas with 25Mb fiber, cable, all sorts of things. Just depends on randomness. There is no one to contact to request, or get future rollout plans, because national companies forward all calls to central call centers, and don't know how to even contact local offices. Local offices are very, very quiet, and don't publish info, or numbers. If you do get someone, most of the time, you won't get answers from them. In our state, they pretty much went away with local oversight, and now give out statewide franchises. So you don't even get to show up to town hall meetings of the franchise board..
I went on COBRA a year or two ago when I switched jobs. I was pretty shocked at how much my insurance cost ($1,440 a month for a family of 3). I was used to paying about $600/month for it. Until I had to pay my employers share, I had no idea how much the insurance actually cost, and I can now see where raises went the few years before.
I know firmly think all employers should have to show the employer paid part of insurance coming into your check, and then going out, pre-tax dollars, just like 401k and stuff. If people looked at their Year to Date totals on their pay stubs, and saw that they paid more in insurance than they did in state taxes, maybe, just maybe we could finally have a real conversation about health care. Its scary how many people think their insurance is free, or a few hundred dollars, when its often several times more than what they pay out of pocket.

There has long, long been a rumor that DeBeers will never open an "official" office in the US..
Yes, I believe you are right, I was thinking LLC.. I either exceeded my caffine limits, or have not quite yet met them.. Its a thin grey line :)

Why no edit button Slashdot? that should be you can NOT sue Bill Gates....

or, a one cent per share 'fee' on each trade. That would be fine with people planning to hold for a bit, but decimate the HFT crowd.
