In that case, they would most likely be able to afford a atomic clock.
Especially since you can buy one for $100 bucks at walmart.
GPSes aren't exactly hard to come by and are the closest thing to having an atomic clock as you can get without owning an atomic clock... and are more than accurate enough when you start distributing the time over an unpredictable network.
We already have the near perfect clock distribution network orbiting us for those who need good synchronization.
Consumer grade GPS device accuracy leads to a clock accuracy of about 1/10,000,000th of a second, you can go up from there. If you distribute that time to anything more than about 10 feet away, you're off by 1/10,000,000th already without including any of the latency in the hardware that distributes it (i.e. network cards). Put it through a switch? You're now well down to under 1/10,000th of a second in useful accuracy.
In short, anyone using anything other than a GPS to time sync their standard commodity pc or server hardware is an idiot.
You use NTP to sync to a timestamp close enough for logging purposes on normal systems. You use GPS to sync systems across large distances that still need to be coordinated accurately for logging purposes. You use Atomic clocks when you need microsecond resolution which only matters to the absolute highest end machines that actually do something useful in a microsecond. (Keep in mind, just because your PC can run a few thousand instructions in a microsecond doesn't mean it can actually do anything USEFUL in that time with any information.)
but having a fat pipe does not "reduce your latency".
Yes, it does, most certainly, the laws of physics do require it to do, and I'm still ignoring link saturation/collisions or protocol overhead/processing on the link ends.
A packet of equal size takes longer to travel down a slower pipe as all the bits are literally 'bigger' on slow pipes. A bit at 10mb (on an ethernet 10mhz carrier) takes 1/10,000,000th of a second to transmit. A bit at 100mb (on an ethernet 100mhz carrier) takes 1/100,000,000th of a second to transmit. It it completes transmission literally 10 times faster. It doesn't go down the wire any faster, it just takes less time on the wire to do the same thing, which results in lower latency.
Does it matter? No, the difference is already so far below anything a person can detect that it doesn't matter, unless you happen to be using a dialup line.
You're assuming the input thread is tied to the display thread, I assure you in games where input matters, the input thread and display thread are not one and the same.
UT3 doesn't tie the two together, it is entirely possibly to provide UT3 with multiple inputs per frame and have it respond to all of them. The same is true on console games as well, a prime example is Forza.
Again, your LCD display has an inherent delay of 40 - 80 ms as well
WTF? Your might, I assure you mine doesn't. I have bought a new LCD monitor in the last decade though so that might have something to do with it.
Your entire post is made based on assumptions that are wrong or only true for games that don't actually need twitch input, perhaps you should let people who actually write games talk about how they are written.
store-and-forward switching has been 'low end' for years.
Layer 2 and 3 cut-through switching has been pretty standard on anything but shitty routers and switches for years.
The dinky switch you have in your home is more likely a hub, with switches between 10 and 100mb (and Gb possibly) so it doesn't do store and forward either.
The only store and forward packet switching your going to see now is for the SYN packet, after the routers have the paths cached for a flow, thats done.
All you need to route/switch is the header, which is only a couple handful of bytes and not the whole package.
But to make things clear, x86 is a bad architecture,
But to make things clear, you don't know what you're talking about.
x86 is nothing more than a model at this point, what drives it under the hood can be just about anything AMD or Intel wants, as long as it appears as x86. There is nothing inheriently wrong with x86 compared to ARM, just neither AMD or Intel have spent years making their cores power efficient. ARM and all its licensors pretty much do just that, all the time, when working with the CPU so its far better at it and not nearly as powerful in the raw performance area.
There is no physical reason that x86 and ARM based processors don't perform nearly identical from a power to performance ratio perspective other than no one has bothered to do so.
Anyone who spouts 'x86 is a bad architecture' is an idiot who simply doesn't have the slightest clue what they are talking about.
And thats a big indication that you don't know how to communicate effectively if you're saying that often, perhaps the problem is a little closer to home than you realize.
I can sneeze without a Facebook account and get 60k people involved. When you're using a big popularity contest where you being friends with someone makes them more popular than anyone who can be your friend is going to do it.
There should be a ban against being a live and using facebook at the same time.
I've known plenty of girls who play MMOs who don't really have that big of a problem with it. The only ones who did had a problem because they tell everyone loudly, attracting attention to themselves.
I highly doubt you get a significantly higher number of people saying anything to you because of the common assumption that everyone online that says they are female turns out to be a 40 year old fat bald man with a built in sweater.
I call bullshit on your claim, especially when you can just say 'shut up or I'll call your mommy since I know your real name (or their real name)
So in short what you're upset about is that you're no longer going to be able to be a complete fucking douche in WoW because someone is going to come kick your ass.
All in all, I think thats great.
Also, contrary to popular belief, the Internet hasn't changed the statistics on Rape, abduction or stalking. The stats have remained pretty much unchanged since they've been taken by the FBI for 50 or so years. The only difference now is paranoid idiots like yourself see something on the news and think its common. There are roughly 307 million people in America, LOTS OF THEM ARE DOING BAD, STUPID, DANGEROUS SHIT, and have been since the dawn of mankind. Posting things on the Internet doesn't actually change the odds, real name or alias.
Finally, as I've said over and over, its REALLY easy to figure out who most people are given very little information about them and Google. I've yet to come across someone who is actually anonymous enough that I can't figure out who they really are.
Your anonymity on the Internet died with anon.petit.fi (for reference, using anon.petit.fi doesn't really do you much good with things like Google around anyway)
Did Blizzard ever stop to think that many (most?) people play their games as an ESCAPE from real life?
I think... Blizzard realizes that. But did you ever stop to think of any other group activity where it is entirely acceptable to interact anonymously? Even people in AA know each others names. If you want to be anonymous, go play with yourself, solo, uno, without others so you don't have to agree with standard/established/ACCEPTABLE social contracts.
Anything on Blizzard forums goes on Google
Pretty much EVERYTHING you do online ends up on Google. With a minor amount of personal information about you, certainly things your boss would have I promise you I can find you, probably down to your home address and telephone number and certainly most of your user names online. Its not very hard at all.
People sometimes have bad days, say things they regret later...on a forum this is all saved forever.
So?
If someone was a dick last week, they'll have a bad day and be a dick next week, or the week after that. You want to make sure people don't think you're a dick? Don't act like one! No one rules you out over one bad day, those that do are unimportant anyway.
Basically you want to be a dick and not have to worry about anyone else figuring it out. Tough shit, man up and stand by your actions or don't take those actions.
There is nothing that is possibly worth saying on the Blizzard forums that is worth sacrificing one's anonymity for.
What could you possibly say that should be anonymous and requires you to be anonymous?
Seriously WHAT THE FUCK do you have to say on a PUBLIC MESSAGE BOARD that you don't want people that know you to know? Thats right, nothing.
If its private/personal/not something for the boss to know... YOU DON'T FUCKING TELL PEOPLE.
People who post shit on public websites and like to do it anonymously are one of two types of people... Trolls, or those with computer courage who don't want to deal with the damage that results from their comments OR voyuers who really want people to know who they are and what they did, but are playing the 'I'm an anonymous tall dark and handsome stranger' game.
Only idiots post things on the Internet that they don't want people to see/know.
ITS A FUCKING PUBLIC NETWORK, STOP WITH THIS RETARDED PRIVACY IN PUBLIC IDEA. DON'T DO IT IN PUBLIC IF YOU DON'T WANT PEOPLE TO KNOW YOU ARE DOING IT.
It really is that simple, repeat it over and over till it gets through the dense rock surrounding your brain.
If I had to use my real name on Slashdot, I wouldn't post nearly as much. I'd make sure to restrict it only to things I was comfortable with all current and future employers seeing. I wouldn't want to screw myself out of a job because I posted something that someone disagreed with.
You do realize that it takes very little effort with the right software to find out who you are in real life... right?
Google has made it incredibly easy for PIs to find out who people are and what they do and never use their real name more than once.
Your alias and UID are a false sense of security you think obscurity gives you. Unfortunately, thanks to Google, you aren't all that obscure in the grand scheme of things.
If you aren't proud of something you do maybe its best if you don't do it? If you are proud of it then hiding it won't do you any good, your true colors will shine through eventually anyway, you really can't hide your personality.
It forces people to attack each other's arguments rather than resorting to ad hominems,
So you've not been using the Internet very long I take it. Not seeing someone or knowing their name has never slowed anyone down on the Internet. Computer courage actually works just the opposite, it encourages people to call each other names because they can be a complete dick, show their true colors and no one will be able to do shit to them for it.
Its not new, I realized this on BBSes when I was in my teens.
Hell, I've read this thread about 3 minutes and already seen 4 posts that aren't modded down that conflict with your statement, imagine if I lowered my comment threshold.
I think you are using a different Internet than me. Remember, AOL is not the Internet, and they aren't rooms, they are IRC channels.
Yes, because comparing rare concerts that us middle aged, been working for years, in good financial standing with a little money in the bank have the same spending habits of a teenager or 20 year old with no job, still living with mommy and daddy.
You go to those concerts once in 10 years, they want to get to 10 in one year.
You've entirely forgotten what being young was like.
If over loading the brick causes damage to anything other than the brick than the system is designed poorly.
The simplest solutions is to have the laptop simply ignore the supply if its not enough. Dell detects underpowered supplies on our laptops at work and will refuse to boot. My MacBook will detect the lower wattage version of the supply its supposed to have and warns me that its ignoring it for charging or something like that.
Since power requirements at this point are going to go lower rather than higher, the simple solution is to pick a wattage thats good for pretty much all laptops now, add 15-20% to it for possible unexpected jumps in the near future, and forget about it.
Laptops are going to use less and less power over time now, they are plenty fast enough.
Apple currently has two for all of their laptops. A higher power slightly older one, and the current lower powered ones.
Its not hard to do and considering the cost to manufacture difference between the lowest power output requirements and the highest are almost undetectable, running one production line makes more money for everyone, even if they're putting over powered PSUs out with little low usage laptops.
Either way, if you can't find a mentor on your own, perhaps you shouldn't bother trying to complete a PhD program? Its not a game of Where's Waldo you know? Generally people tend to get a little further into it before trying to find some one else to do their work for them, you haven't even started yet.
I've not been able to notice page load times in years that weren't due to network IO.
All this bullshit about 'page load times' and 'javascript performance' doesn't mean shit when there is no perceivable difference to the user which is where browsers have been for a couple years.
The only noticable difference is when someone invents some test to show how much better they are than everyone else.
Heres a hint: When you have to use high speed camera's to show people who quickly your pages load... NO ONE GIVES A FUCK.
Jesus Christ would you little fucking rejected tards stop ranting about it.
Having used both Xp x64 extensively and Opera somewhat less so I can say without a doubt that is a great relationship to describe, but not because they are good.
In my experience both XP x64 and Opera have the promise of great offerings, but in reality what they offer is of little to no practical value and all the 'broken' things that come with 'standards compliance' just don't really make it a browers (or OS) that 99.999999999% of the universe gives a shit about.
Its great that both of them can do cool things on paper, but no one cares because those cool things are largely irrelevant to the audience they appear to target.
You're comparing the iPhone using some physical technique to infer the signal level to bar mapping, taking into account all the variables of the phone hardware...
And on Android you're just looking at the source... not even the phone itself...
And this is supposed to be some sort of comparison? Whats next? Submarine A goes 25 knots submerged, Space Shuttle X launches into space at 36k knots. Which one will get you to BurgerKing first?
When you compare things using completely unrelated ways of gathering your input data you find that your results are ALWAYS wrong, even if you can't see it or they agree/disagree with what you thought.
Ahh spoken by someone who cares more about what some guy in a book calls a style of coding than actually getting the job done.
Let me give you a hint, when you spend more time naming 'principles' than you do actually listing a real reason its bad then you make it clear you aren't actually a programmer, you're just a graduate that thinks he has a clue.
I'm sure you're one of those people that claims its never acceptable to use a goto either, to which the simple response is... you don't know how your language works since when it comes right down to it, an if statement is a goto.
