it's a choice between reliability and complexity, and complexity has its own reliability problems. Ideally, the HA solution is best, but it relies on a lot more than the simple solution. The users that get an error can try again and it will work. I did say that it's mostly useful for the app server layer, right?
This is all speculation - the whole idea is to come up with some sort of standard that allows armed vessels while not allowing some private navy to take over a marina. If you show up in a harbor with a locked up BMG and it stays on the boat, that sounds just fine.
Webservers are far less stateless than you might think. Nowadays they practically are app servers. (Disclosure: I did web applications since 2000, so I know a bit about the subject.)
Webservers have no business being the sole repository for these things - the whole point of separating out web from app is that web boxes are easily replaceable with no state.
Session mgmt: store the session in a distributed way at least after each request. Transactions: they fail if you die half way through. Shopping cart: this doesn't live on a web server.
If you require all that state, how do you ever do load balancing? Add a web server and it's another SPOF.
When 5 minutes downtime mean over a hundred complaints in your inbox and tens of thousands of dropped connections, which your boss does not find funny at all, you don't do that error again.
That's right, you move the state off the webserver so nobody ever sees the downtime and tell your boss that you promised 99.9 and damnit, you're delivering it!
"USA" != "America", USA is a subset of North America which is a subset of America.
No, USA==America. North America is a continent, and the two continents together are "the Americas".
If you "yanks" don't was the rest of the world accessing your websites, you can take your heads out of your self-righteous asses and simply block us, I am sure even "yanks" can manage to do that.
This is a US centric website, you wanker. You can come here all you want, but don't assume ithe UK is the center of our universe.
If you ever seek an answer as to why so many US citizens find themselves being treated rudely by "foreigners", then you only have to look at your own behaviour here.
Who're the rudest tourists in the world? That's right, the English.
NOWHERE in the original question was any mention made of the vulnerability of the US grid with those of other countries, you know, that CONTEXT thing you were on about.
They may also have problems coming into foreign ports, if weapons are not allowed. Just think of the trouble a common merchant ship would have, if it came into a US port with a 5" deck gun, and a couple 50 cal machine guns mounted up on it.
What if the guns were required to be dismounted while in port (locked up?)
The merchants get AR-15's and 50 cal's. The pirates get 50 cal's and RPMs.
Why do people always assume an escalation? There's no justification for it.
Most incidents of gun violence are domestic &/or perpetrated by someone you know.
Most incidents of gun violence involve gangs and drug dealers/users - it's reasonable to expect that they know each other. If you aren't a banger or a dealer, I would wager that your most likely encounter will be from someone you don't know.
To quote the alleged post, "Seems like you're very willing to invite a man you only know from the Internet over to your house -- have you done it before, or do they usually invite you to their house?" - this is trash talk if ever I've seen it. What's next, suing over yo'mama jokes?
I met a rottie pup last year - cute, sweet, and resembled a tube of meat with a tail on one end. My friend from back east knew a guy with a full grown rottweiler - biggest hazard there was that she'd jump in your lap (90 lb dog) and slobber on you. Physcopath, indeed.
Blacks eating in a diner is hardly as hazardous as some white trash idiot and his 'attack dog'. This decade, the attack dog is a rottie, but it's been doberman, german shepherd, and a couple others in the past. Deal with the white trash idiot and his penchant for large, poorly trained dogs.
perhaps the biggest killer on the roads is a drunk behind the wheel.
No, they only kill a few thousand per year - the actual number isn't tracked anywhere. What kills people on the road is driving like idiots and relying on your car to protect you.
The type of person prepared to drive while stoned is pretty much the same as the type that will drive while drunk.
Stoned people drive better, largely because they know they're fucked up and drive very carefully.
One other problem with HDMI is that although they have a nominal max cable length of 15 feet, you're lucky to get it to work if the cable is over five feet.

No it doesn't. It has rules on signal performance and if you can manage that, it can be a mile long.
Talking about scalability in terms of infinitely fast components is just silly, because no such component can ever exist.
That's my point. You can't talk about the scalability of abstract concepts because they can never actually exist. Only implementations can be scalable. If you want to talk about ratios, then an arbitrarily fast Turing machine can handle as much work offered in as little time desired: that is, it has infinite scalability. Such a concept is clearly nonsense.
Please, limit yourself to the real world instead of trying to embarrass yourself with generalizations to nothingness.
You sound like a college student. Now, given your turing machine, if you have sequential operation, then two turing machines can complete the same work in, um, the same amount of time. Scalability = 0. How is that implementation driven?
This means that as soon as someone proclaims "We know the rules of Economics!", someone else is going to look at those rules and either game them to their benefit, or rewrite them to better suit their own purpose.
So what you're saying is that it's really just Calvinball.
you dumbass! All you have to do is deny/* or whatever and google won't index you. More likely, this is just posturing for a bribe - maybe it'd work better if he ran a news site.
Good question - I would expect it's mostly relevant for those DCs that do underfloor cabling. Cooling capacity is measaured in kW, I believe - the ability to remove heat. since air has a low specific heat, it shouldn't matter much, so long as the temp is stable and it isn't very humid.

or just hire someone to host your boxes, depending on what they're for.

if it's a webserver, what's the big deal? Run 4 and if 1 drops off, stop sending it requests. For an app server, I can see the advantages.

I thought that was part of the USB spec, what with the isochronous transfer and ad all.

you are suggesting that someone hooked up a life critical system to the public internet? That in itself should be a felony.
Even though you don't need a license to enter subway, the government can stop you at their whim.
Hmm, almost missed the sarcasm

Compiled code might run 10% faster, but not that much faster.
More like 10x - this is access, which is quite possibly running VB6.
Most license suspensions are for not obeying administrative rules
Mostly, this means not paying fines, or some BS about child support.
Even at that, though, how do we expect Bob, who lives 10 miles from town, to eat if he has to walk, in the middle of Winter to get his food?
Good question - not like we have a transit system worth a damn.
Left this part out: (Not a DC admin)
