False, Android has overtaken the iPhone for one quarter.

Here's a good reality check on the size of the platforms. The OpenFeint gaming network for iPhone/iPod has more users than there are Android handsets in existence.

And in the long run open platforms do much better? How so? Huh? Look I've been using linux since kernel .96 and FreeBSD since the original PORT, but these sort of statements make no sense. They are nebulous and "weasel statements".

Comment There is a reason for leased lines... (Score 4, Insightful) 256

... and if you think it is about latency you are mildly retarded, as are the writers of this general knowledge article.

Leased lines in general have better SLAs but that isn't even much of a point anymore as they cheaper products "claim" to have similar ones. The difference here is how good is that business class dsl/fiber support at 2am? What are the odds they are actually going to be willing to send someone out to the telco closet right away if there is an issue? You buy leased lines because you need *real* support of the SLAs... not this, "well we were down for 5 hours, so how about we credit you a day off!" bullshit.

It's really scary for what passes for "good advice" these days.

Comment Re:Backup to tape? (Score 4, Insightful) 256

You sound like someone who has never been responsible for long term backup storage. Stuff isn't just thrown on a tape and stored offsite for years. Responsible DR requires you to constantly be shifting all your long term storage onto new methods, constantly. You wouldn't have MDF hard drives with valuable data on them, or even legacy data as all that data should have been MOVED and VERIFIED onto current media.

Comment Re:A better explanation (Score 2) 198

What I find interesting is that the current OS most people use, with the exception of
some RealTime and big iron custom dealies are still built in such a monolithic way that
it becomes more "profitable" to the user experience to still ramp up single cores as
opposed to having most cores running at the same speed.

With the exception of some high demand apps like games, extensive math apps,
and stuff that could or should be offloaded to GPUs desktop OS don't need a VERY
fast single core, they instead need lots of equal cores with fast context switch times
coming from the OS.

For example the fastest core in Win7/OSX for a desktop should be the one handling
the UI but it doesn't need to be THAT much faster than anything else. Instead all the
tiny little apps need to be sent around to as many different cores as possible when
they aren't multithreaded... unfortunately none of the current schedulers are that great
at this in consumer land. Even worse the kernels can have so much locked in that
you end up with lots of things stuck on a single core that could exist elsewhere.

Such a shame that true mach never got the switch times down because of the
huge separation in "drivers" or "kernel features". QNX definitely got this right,
but they never took multicores seriously, perhaps it is a much harder problem than
I am assuming.

Comment Ahhh OS2. (Score 2, Interesting) 432

OS2 is what pushed me unto the unix for good. My bad ass 486-25 sx (with math coprocessor), 16 meg of ram and WHOPPING 1.2gig full height scsi drive was hungering for some more fun. I had been running a hodge podge of operating systems and had settled on DESQView/X. I had it all, running windows 3.0 apps, command shells, x applications, even X apps from remote! But then a new version of OS2 came out (2.0? 2.1?) that promised me everything DESQView/X was giving me, but running with out DOS! THE FUTURE HAD ARRIVED!

OS/2 promptly ate my partition table and destroyed all my DVX, windows and dos partitions.

I was so effing pissed that it did this without really asking me anything that I swore it off. Fortunately something sorta BIG had just happened there on them ol' USENETs: The new 11 Floppy version of Slackware dropped. I installed it... and never looked back.

Well it is easy to bag on things in hindsight, but in 01/02? If you were doing something like running thousands of monte carlo simulations the Alpha was untouchable for commodity hardware. I won a bitter sweet war when I swore up and down with any data I could muster that Sun e420's fully populated couldn't even remotely touch a lowly ol' DS20 running about 1/3 the cost. Ended up with a lot of underutilized sun boxen.

Comment Re:Atheists Unite... as a religion (Score 2, Informative) 845

Rational Agnosticism is very solid position. The best summary of it I came across recently, "you can know that someone loves you, but can't prove it.". RA contends that everything, can and does exist and as this is something beyond the thinking of our human minds, who are we to say what is or is not god, since really it's all the same stuff, the little bit and pieces of our universe and other universes making up the infinity. A rational Agnostic doesn't believe in an intervening god, or a god who may even be aware of its creations, it's simply saying, there is a whole lot of stuff out there we don't understand and may never understand so sit back and enjoy the ride.

Comment These unix server numbers are crazy. (Score 1) 414

One per 70? Perhaps if you are running a ton of clone servers or heaven forbid working at an ISP handling boxes for customers.

In the *real* world one normal admin per 35 or so is considered more normal for unix staff (with a senior admin for every 3-4 normal admins). While I have seen the numbers quoted by the parent they were very for generic servers in function and basically tons of copy (virtual) boxes. In addition if you are running a good deal of unix servers you more than likely have a lot of different functions spread out among clusters, one person responsible for all these apps as well as keeping the boxes well maintained, troubleshooting upgrades, etc... can be quite tiring. Unix boxes these days tend to do significantly more than they used to. On the flip side, managing unix boxes these days is quite easy thanks to ssh/cfengine/puppet other automation.

When I first started doing unix for pay, mid 90s, we had one admin per two servers which was a mirror of the typical university environment where there were single admins for important machines and tons of lackeys for all the sun/hp/dec desktops. By the year 2000 this had grown to around 20 servers for each admin, with senior staff expected to be able to handle functions across any cluster. These days if it is a smaller company, there's one senior admin, who may or may not be the Network/IT manager and they typically handle 30-40 servers if there are a number of functions spread out. Of course having tons of similar boxes makes this number much higher. The most I've ever handled was 165 servers spread across two admins, three sites, four major applications, tons of clusters, including DB/Application/LB/Development/etc...

Also, if you have 70 unix servers and only one admin, the point of failure for your organization is beyond catastrophic. That poor lil' admin guy is going to get many of the "what happens when a bus hits you" questions from 3rd parties/partners/other departments.

Slashdot used to be quite fast with the aggregation, it is quite terrible now. When CNN or the BBC are reporting tech news faster than a site that is supposed to be for tech nerds that's a good indication of the quality and speed. What's worse is this write up actually has misinformation in it that was disproven ALREADY... but this is so slow coming here, well...

Comment One thing that always bothers me. (Score 1) 315

Europeans have this grand view of America based primarily on Television and the East Coast which looks rather terrible. Europe's countries are like some of our bigger states. The differences between the basic values of people in California, Texas and the upper East Coast are quite pronounced. Hell, those of us in north California, don't even want to be part of the US anymore. We'd be just fine going on our on way with our friend in Oregon and Washington. Having one of the world top 10 economies and being nearly completely self sufficient. As it is now the rich states like California subsidize the many failed states of our great union.

But back on point; the USA is quite a diverse country with many different mindsets across the entire spectrum depending on where you are. Don't assume just because someone is American they believe X. That's akin to saying all French and Germans think the same.
