It's not fair and the house always has the advantage. This is a given, otherwise the casino wouldn't profitable and continue to exist. When you choose to play a certain machine part of the gamble you're making is hoping your machine doesn't malfunction.
SLA and reboot monkey support aside, another good reason to stick with a leased line these days is upstream bandwidth. Your 60 meg cable may only have an upstream of 2 (which is how Charter works where I am). This may or may not be important depending on your usage patterns, but it is very often overlooked.
There appears to be a paved blacktop path that runs parallel to the road on the west side. I'd hazard a guess that this path is for walking and biking since we have these where I live and that's exactly what they are for.
HP laser printers are workhorses and IMO the gold standard in affordable printing. I remember one ancient Laserjet 4 that was still chugging along after a decade of use and this is by no means atypical. Most people would rather buy a cheap $50 inkjet then spend $500 on a decent laser model, even though the lifetime costs are far, far less.
I still use a 4 Plus as my primary printer at the office. It originally used an external print server but I found an internal one for $5 at a university surplus sale a while back. I also picked up a 2100TN at the same sale for $10 to take home. That one replaced a 3P that I gave to my girlfriend's parents who were running through ink like crazy. They didn't believe me when I said I had a printer that would go for years between replacing the cartridge. The 3P is still going strong on the same toner cartridge it had when I gave it to them three years ago.
I'll never buy an inkjet or recommend one. Laser always.
The pictures I've seen with Google servers are caseless and don't have many fans other than CPU and probably one in the PSU. I don't think that Google can be compared to the typical rackmount server the rest of us would use.
I think containing the hot isle is probably the best way to go as well.
* When I'm working in a datacenter I'd rather be walking around in the cold isle (~70-80F in a modern datacenter) than the hot isle (100-120F if properly contained)
This is probably diverging a bit on the original question, but seeing your 70-80 "modern datacenter" range reminded me of something I've wondered about lately: Has anyone researched the tradeoff point between when the server cooling fans start spooling up and turning the temperature up to run a "hot" floor? Running fans at a higher RPM certainly translates into more current draw than if they're running at their lowest speed. Sure, the equipment can stand running hotter and you're being "green" by not running the A/C as much, but are you just trading that for extra power wasted on spinning a whole lot of fans faster?
Wall mounted A/C? Icky. I've only seen that in one other place that my local competitor calls their "business class colocation facility". They have the things randomly all over the place. I can't imagine any way to tame that kind of airflow.
Yeah, what you do is going to depend on how your room was designed. Mine is 100% ducted, so it doesn't matter. Just drop curtains down from the ceiling to the top of the racks and bam, done. Each cold aisle has supply vents and each hot aisle has its own return. I don't know if you'd call that hot or cold aisle containment; I suppose it's containing both.
What you're describing with underfloor cold supply already has hot/cold containment: the raised floor. Simply extending that to enclose the front of the racks is the logical choice.
We need to go back to the moon. If not just for the exercise in doing something we haven't done in decades (leave LEO and land on something else). Hell, we can't even send a person to orbit the moon right now let alone skip all that and go straight to Mars starting from scratch.
just like the need to pull the lever on a column shifter toward you in order to shift it.
Not true. On many cars (I won't say all because I have not seen every car) the locking key that the button/lever action moves is notched in a descending pattern so you can push the shifter into neutral. What I said was, in case you need help reading:
I did sit in a Prius at an auto show once and there's nothing mechanical about the drive/park/reverse selector.
I said nothing about destroying the engine, merely that the Prius shifter is not mechanically linked. You appear to have confirmed this as on a car with some kind of mechanical link you don't need to hold it in a certain position beyond a delay to to confirm your commands.
Wikipedia also says: "Some shifters with a shift button allow the driver to freely move the shifter from R to N or D, or simply moving the shifter to N or D without actually depressing the button. However, the driver cannot put back the shifter to R without depressing the shift button to prevent accidental shifting, especially at high speeds, which could damage the transmission."
That said, why is it in these stories of runaway acceleration, that nobody slaps the thing into neutral and hits the brakes? The stories always read like "I was powerless to stop my deathcar!" but drivers have lots of options in situations like that. You can even just turn the car off and hope you haven't picked up a vacuum leak.
I hear that these cars are "too smart" to let you shift while driving. I drive a stick (my preference) so I have no idea if that's accurate or not, but I did sit in a Prius at an auto show once and there's nothing mechanical about the drive/park/reverse selector. It merely indicates to the computer what you would like to do.
Three of those that you cited were incidents that caused loss of crew and vehicle, some quite dramatic. Had they kept the resulting investigation internal for those were very public events, they could have been accused of covering something up. Or maybe they wouldn't have truly found the fault, or deluded themselves into thinking it was just an accident. What if we never knew that engineers were requesting imaging of Columbia? Or that engineers were trying to say "no go" to Challenger? Whatever they were doing with their own internal review processes apparently weren't working quite right, so get someone else to look at it and give them a kick in the ass if needed. It's not really ironic at all.
I would not recommend buying a Mac - I bought one because that is the only way to develop for the iPhone/iPod Touch (still haven't gotten around too it). It is true Mac offers little options. Some Mac junkies like to argue that you get the best technology, and you get what you paid for - however, since you are on slashdot, chances are you will not like the 'dumbed-down' approach Mac OS X takes. As with desktops, the only upgrade path is buy a new Mac (unless you have a Mac Pro), limiting your opportunities to add a new video card, or maybe an additional hard drive, etc.
You used to be able to get a nifty different architecture out of it when it was still the PowerPC line, but these days, yeah, you're just getting premium prices on commodity hardware. The only advantage is that you're getting a system with pre-screened parts and an OS that are known to work together (in theory, nothing is perfect, but still less permutations than WIndows has to deal with).
This is false. Google details at some length the causes of the customer-facing outage.
I only sort of skimmed over TFA to get the big points, but if you can point out the part where they explain why 25% of the servers lost power, I'd appreciate it.
That's what I was thinking; the local battery design that was previously praised became the fault. A large central UPS can monitor and test its batteries more than just plugging an SLA battery into the DC side of a server power supply and patting yourself on the back for being a genius. A UPS gives more telemetry, too. How did Google monitor those individual batteries? Not all SLA batteries are perfect. Were they tested and maintained? I'm guessing "no" to both if 25% of the servers lost power before the generators started (probably 10 to 30 seconds, which isn't that much). How long was the generator start window? TFA doesn't say anything about that.
Google fails to address what caused the outage (beyond that the power went out). I've read some comments here saying that's not important, just how they handled it afterward is important. I disagree; if their no-UPS design has some fundamental flaws in it, they should admit it and address it, even if that means going back to a traditional centralized UPS.
Not "natural". There is no practical limit to how many fiber optic cables can be run underground. You can bundle 100 fibers (100 companies) into the space of a single water pipe. The monopoly is not natural, but instead government imposed (via licensing to one cable company).
We didn't start out with fiber optics. Typically one entity has the existing right of way with central offices to go with a massive copper plant.
Nitpick: SMTP with opportunistic TLS is *not* SMTPS. The latter is on port 465 and is like HTTPS where you start encrypted. Opportunistic TLS starts out unencrypted but at some point STARTTLS is issued and the connection switches to encrypted at that point. If not, it continues in the clear. This way, both encrypted and non-encrypted communication are supported over the same socket.

Every machine here in Nevada says right on the front "malfunction voids play" or something similar.
I'll throw another one on the pile: symmetric bandwidth. The common ADSL and Cable connections sold as "business class" have a horrible upstream rate.
SLA and reboot monkey support aside, another good reason to stick with a leased line these days is upstream bandwidth. Your 60 meg cable may only have an upstream of 2 (which is how Charter works where I am). This may or may not be important depending on your usage patterns, but it is very often overlooked.

Technically it's a recommendation: Section III, chapter 2, subsection V. Heat stress is Section III, chapter 4 with plenty of formulas.

Could such a plan work, or is it simply too late to get people to give up their Facebook accounts for something that gives them more freedom?
This plan assumes that your average Facebook user wants freedom and/or privacy.

Actually no, Google doesn't use UPS systems if this is one of their designs that uses one small sealed lead acid battery per server.
Coax gives you one braided shield and one center conductor to carry RF. It's not even remotely like UTP.
