I just reset my Google cookies and logged back into gmail and all cookies set expire at end of session. After I "logged out" of gmail a few were left - S,TZ.GMAIL_RTT from google.com, and GMAIL_LOGIN from mail.google.com - all still set to expire at end of session. I'l lhave to exit this browser to figure out where those go away when I exit Firefox.
What do we know about Google's architecture? Not much more than what Hotmail discloses about their architecture in their article.
I'm not trying to be an advocate one way or the other - I think both Google and Hotmail are doing as best they can with the architectures they are constrained too. Hotmail has to eat their own dog food, for better or for worse.
Not much more than what TFA describes. The heart of the article (for me as a system administrator and "architect"):
"PS If you rely on scale up, you'll probably get killed. You should always be relying on scale out."
So they are thinking about this at MS. It may not work as well in Windowsland as BSDland right now, but they have their all-seeing eye turned un that direction.
And when Google says "large number of commodity machines" (as in your mapreduce link) I suspect they are just being their usual smart-ass selves. Those "commodity machines" are no doubt just as optimized, scrutinized, and standardized as Hotmail's.
But essentially you are right, except for the AM-talk-radio terminology. Let's use the term "temporary technology". Someday, gasoline will be $10 per gallon, and other technologies will be cheaper. Hybrids will be considered quaint kludges, collector's items, and there will be an aftermarket for handbuilt, ungodly expensive battery kits.
AT first, it was BSD running on a bunch of identical custom-made sub-1U servers. But No! Then it was replaced by windows boxes . . . racks and racks of 99c Fry's keyboards velcroed to the backs and fronts of racks, with miles of small-gauge track, upon which ran diabolical steam-powered robots, each with a single arm and with fingers at the end, forever fixed at the precise spacing to stab the keyboards' CTRL-ALT-DEL keys. Noisily the robots rumbled back and forth on their appointed rounds . . .
I helped out with some research on automated vehicle guidance back in the late 80s. The chief objective of the system was not to automate stopping but to enable "radical tailgating" as a way of increasing freeway capacity.
As it stands now, once traffic flows reach about 2000 vehicles her hour per lane, speeds start to fall off rapidly because of driver's reaction times and the inherent limits of controlling a 2 or 3 ton vehicle. If a computer controlled braking, theoretically the reaction time component could be eliminated.
Obviously there are legal issue with this, and with an automated system doing the work drivers wouldn't be able to brag as much about what studly drivers they are.
However, a system that allow you to automatically follow a safe humanly-stoppable distance (2 sec or about 1 car length per 10 mph) could still have an impact on freeway capacity by just smoothing starting and stopping impulses, and reducting tailgaiting - tailgating slows down traffic a LOT at high volumes.
And if you think such a system might be hard to widely deploy, just look at in-vehicle automated routing and navigation systems, which were a pie in the sky 20 years ago. (I used one in my research - this was before GPS and it used dead-reckoning from the speedometer signal and a magnetic compass. Needless to say, it got lost a lot.)
You will never bag a supermodel with a cheapass RAID card and 10 drives you coddled together from crap you bought at ComputersRNeat.com. And sometimes it's good to just have nice stuff around the house.
Cheap RAID sucks. The X Serve is actually reasonably priced, $3 to $5 per GB, a little higher then SCSI-attached Dell stuff (Which can be garbage. You've been warned.), a little less than IBM or Sun, FC or iSCSI based in the $6 to $7/GB range. You get what you pay for, basically.
I'm not a bigot - I have to buy 10 TB of disk in the next year and Apple is one the list.
The word on the street is that discs recorded at speeds commensurate with what they will be played back at might be more readable, i.e. recording at 36X is more reliable than recording at 4X.
Granted it wasn't possible to burn discs at 36X in the pre-2000 time frame, but the few I have from that era I still use from time to time and they are fine.
Wish me luck recovering my FORTRAN programming archives on 1/2" tape. I'd have had better luck translating the files into 300 baud audio files and transcribing them onto vinyl LPs.
I think mostly what us nerds object to is the conversion of two commodity "nerd tools" into an overpriced status item.
We want an Open Source sunglass+MP3 player!
I am much more worried about these pandemics:

A Flu Pandemic?
·
· Score: 1
- Diabetes - Obesity - Lack of medical insurance / out of control medical costs - Lack of interest from the medical and pharma mega-corporations - Overall stupidity (with respect to all the above)
Speaking as a 'Merkin, these are going to do far more damage to our national security than a few hundred thousand dying of the flu in a year or two.
Your mileage may vary, especially in other countries.
To bad the site has hijcked the term "open source". The less the term is associated with crackpots the better.
By the way any big storm will create "seismic disturbances". Big waves crash on shore, and heavy stuff falls over, and seismographs can pick this up. Big woo.
And falling barometric pressure can make your joints hurt, as the pressure inside your body equalizes with outside.
Well, at least the development and test process would be fun.
And based on what I have heard, most SATA raid-5 controllers are not quite ready for prime time, although I did recently interview with one outfit that was running their whole enterprise on Pogo Linux StorageWare boxes:
I dunno. I would want to pound the crap out of them for a few months before I committed. Worse, in my last job we had zero budget and a bunch of ancient DL380s with hardware raid; nothing bad ever happened but it kept me awake at night, mostly thinking of new scripts I had to install to make sure every box was at least rsync'ed somewhere else. Now, I'm fortunate to work at a place that can afford EMC and Sun, SCSI and FC stuff. Nothing ever breaks, ever, and I sleep like a baby.
Somehow every time an article like this gets posted, the poster forgets to mention - OBTW, my budget is only.....
If you can afford a 25TB sized storage system, that will scale by a factor of 40, and still be recoverable, and you are asking slashdot for suggestions . . . really just give up and call EMC or their ilk and be prepared to write some zeros in your check.
OTOH it can be done - 6 years ago I interviewed at Up and Coming Photo Site that planned on archiving every photo uploaded by every user for all time for free. They had standardized on a really cheap and no doubt hideously dodgy open source software raid-5 white box design that they could churn out for a few kilobucks, and were building them by the hundreds and connecting them with NFS. With SATA RAID-5 controllers, ReiserFS, and the Linux VM in much better shape now than then, a project like that might actually be fun!
The internet routes around this damage just fine. Technically nothing prevents my ISP from pointing their DNS serervs to a "free" root zone in Europe, Brazil, India, etc. Heck, I can point my home resolv.conf's at any number of "free" DNS end resolvers that I am sure will be popping up everywhere.
However, if the US gummint tries to tell my ISP which root servers to point to, or blocks DNS service from offshore, we have got a serious problem on our hands.
I think the danger is more to us 'Merkins forming our own splinter Internet, putting us in the same camp as other bastions of free speech like China and Saudi Arabia. The fact is that our own gummint meddled in Icann's business over.xxx and sparked this mess.
>>> ""My experience is that if something has to be done, just do it - don't ask! They will thank you later,' he said.""
Now that's the spirit! Coming from a Big 4 accounting firm. Is my tax dodge legal? Don't ask! Where's my fee! The partners needs new Hummers!
(Although I have a feeling that internal IT at these firms tends to get thrown in dark basements and told to fend for themselves.)
That being said, just as "nobody ever got fired for buying IBM",nobody ever got fired for setting up name service, a mail relay, or a firewall on a BSD box.
As a reasonable person, I hereby declare that the Onion should tell the White House to piss up a rope, because I would find them NOT GUILTY if I were on the jury. I see no false impression of sponsorship or approval, etc.
There, that ought to get me out of jury duty for this trial!
>> which no ISP in their right mind will direct their DNS servers at. >They will enact laws requiring it.
This would be hilarious! Let's complain about Evil US Gummint Human Rights Oppressors controlling root servers (which they don't anyway), and then the only way to enforce this is - governments ordering their ISPs to use their own root servers!
Just pay the EU or UN ministers or whoever the bribes they want and this tempest in a teapot will go away.
The 815 isn't all that impressive anyway unless you need all the fancy-pants extra features. I traded up from a 7-yr-old StarTac, and I think the StarTac had better voice quality. I got the 815 before EVDO rolled out in the SF Bay Area, and in a non-EVDO area (without a menu hack) the batteries will run down in 24 hours standby, and about 45 min talk time.
It has good battery life as long as you stay in your EVDO service area, the ringer is insanely loud, and the camera is surprisingly good, but until EVDO rolled out I would have traded for a 710 if Verizon had still offered one. Oh well, the 815 was essentially free under "new every two".
I have a 2 yr old A70 and the images have just gotten worse and worse over time: noise, streaks, and tiny blue spots all over. I guess since it hasn't failed completely yet I'm of luck.

I'll leave it to the Apple fanboys to riff on this ad nauseam, it's just getting harder to enforce the no-Intel rule in our house is all I care.

No further comment. Just read the newspaper. It a Golden Age for Evil Mutants abound, human and otherwise.
