Many video codecs effectively "start again" every so many frames anyway.
You can sometimes see this with static text superimposed on video and then compressed heavilly. The text starts with a load of artifacts, over several frames they clear up then suddenly the artifacts return as another keyframe hits.
IMO there is no question that when IPV4 addresses become scarce ISPs WILL push home users behind nat (with maybe an option to get a public IP address at a price high enough that only geeks pay it) to free up IP addresses for more lucrative customers.
I don't particularlly like NAT either but that doesn't mean it won't win out as the "soloution" to the IPV4 address shortage.
In defense of the old black MacBook, however, it was not the same as the white ones. It provided additional storage space and more RAM. Maybe not $200 worth, but this is Apple we're talking about. You could make the higher of the two white models have identical specs to the black model by using build to order options. Even when you did that it still ended up considerablly cheaper than the black model.
What i've found with apple is if you start with a mac and try to find a PC that's as close as possible to it you will indeed get similar prices.
On the other hand if you start with a list of requirements and find both a mac and a PC to fit that list the mac will often end up far more expensive because you have to buy far more than you need in some areas to get what you require in others.
Do you really require server class processors and support for massive ammounts of memory or did you choose the mac pro simply because it is the cheapest mac with exapansion room.
One big issue is file handling. On windows practically all apps use the standard windows file dialog (or a very minor variation on it). On linux there is a huge hodgepodge with many of them not showing standard locations requiring manual browsing to/media and guessing while of the subdirectories is thier usb stick and which are just stale crap. The gnome file dialog is also slow as fuck because of attempts to identify files by contents.
I've also noticed clipboard support for anything more than plain text to be poor on linux though I belive this is improving
One thing that concerns me about chip and pin is if a criminal does manage to get your pin (e.g. through a hidden camera or just plain old shoulder surfing) then his authentications are indistiguishable from yours.
So if the bank were to accuse you of lying when you reported such a fradulant transaction would have no evidence otherwise.
Running as root (local privilege escalation) isn't the same as running in ring 0. No but at least on a normal linux setup it is trivial to go from running as root to running in kernel mode. Just load your malicious code as a kernel module.
While the details are different the principle of a "bios" that runs on startup and provides sufficiant functionality to allow loading a proper OS from a variety of media is still there.
And I strongly suspect that apples system is just as modular if not more so than modern PC bioses and therefore just as vulnerable to malicious addition of a module.
I did and there are two major issues I see with it.
1: the information was collected from datacenters so there was very little data about what happened at higher temperatures (look at the error bars on thier graphs as you get towards the higher end). 2: they were relying on the hard drives own report of temperature. So if a particularlly reliable hard drive model also happened to overreport tempreature it would totally throw the reports.
Furthermore remember that depending on the details of the machine in question and it's installing the temperature of the hard drive can be considerablly above the ambiant.
the trouble with public transport is the ammount of time you spend getting between the stations/bus stops and the final destination and waiting at the stations/bus stops (which is exasperated if you have to change).
A trip that would take less than an hour by car can easilly extend to over 2 hours with public transport.
Afaict assuming terrafugia meet thier design goals and you are in the US (which seems to be thier target market at least to start with, rules elsewhere will of course vary) you will need a "sport pilot" or higher license to fly it.
Indeed, while I think flying cars like this one may find a niche. I don't think they will ever take off on a large scale.
You will still need a pilots license (albiet only a light sport pilot license asusming terrafugia meet thier weight goals). You will still need a registered airfield to take off and land legally so it will only be worth using for longer trips. Finally it is rather expensive ($200000 iirc).
So I don't see there being enough of them in they sky to have a significant impact.
Of course that doesn't mean terrafugia won't be successfull. A small buisness (Which afaict is what terrafugia are) can be perfectly successfull with a niche product.
Of course with Open Source you get to set the schedule and work it into your budget. With Windows you get a year or two window that Redmond chooses for you to make the switch. Really? The evidence I see points to the opposite.
Unless you are a really tiny operation you will most likely be getting your copies of office and quite probablly windows too on volume licenses with good downgrade rights so deploying new copies older versions shouldn't be an issue from a licensing perspective.
And according to microsofts current lifecycle policy you get you get 7 years of security update overlap. Very few if any linux vendors will provide that length of security upgrate overlap
not to mention the hardware issues. Afaict most buisness orientated computer vendows are still selling thier hardware with XP drivers and an option to get XP preinstalled. Try installing a linux distro of similar vintage on modern hardware and see how much "fun" you have.
indeed, posix acls fix all the issues mentioned above and (unsurprisingly) are really not hugely different from windows permissions (there are differences but those differences are minor details).
Unfortunately on linux (at least on debian and it would appear from my searches probablly ubuntu too) acls seem to be rather a second class citizen compared to traditional unix permissions. I have to install a special package and set a special mount option before I can use them at all and then it seems I can only view and set them from the command line.
Also I would argue the only reason theese rarely occour on home computers is because most home users don't bother with seperate user accounts for each familily member or if they do they just leave the premissions wide open.
Traditional unix permissions leave a lot to be desired in my experiance.
1: there is no inheritance of permissions. That means if as the admin I make a directory that is supposed to be shared by a group read/write for the group anyone in the group can create files in there but they can't edit files created by each other. 2: Only the admin can create groups making it impossible for users to make thier files availible directly to each other. 3: only one group can have access to a directory making group management a PITA.
1: it's very hard to get it perfect 2: you generally lose a lot of performance. This is not an issue when emulating really old stuff but trying to emulate x86 on the comparitively slow arm is going to give terrible performance.
Sometimes you can get away with it. Apple did a pretty good job all considered. Sony screwed up pretty badly imo (even thier PSone emulation has bugs and thier partially software PS2 bc on the european PS3 was pretty terrible at least with ratchet and clank, the american PS3 with bc had pretty much all the PS2 hardware inside sidesteping the emulation problem). I haven't tried the XBOX 360 myself so I can't comment on that.
I doubt some small netbook vendor would have the resources to do this well even if there were suitable (as in faster than the intel chips they are trying to replace) CPUs on the market.
That's kind of a canard. It's less effort (and cheaper) to train users who are used to XP and MS Office 2003 to use Ubuntu and OpenOffice than it is to train the same users to use Vista and MS Office 2007. Probablly (I think MS made a major tactical error by radically changing the interface of office) though i'd argue it's probablly just as easier to train them to use vista+openoffice.
Also at least for larger buisnesses who get their copies of office through volume licensing sticking with windows XP and office 2K3 is a perfectly viable option for the moment and i'm sure is what a lot of buisnesses will do during the recession.
As the old saying goes: if it aint broke don't fix it!
Every digital camera I've ever used has had a 100+ ms delay between pressing the shutter button and the picture actually being taken. hell where did you find one that good? I just googled for a comparision table and found the best cameras to be arround 0.2 sec with the worst being well over a second.
Yes we IT guys know the non dumbed down user admin tool is in administrative tools-computer management (I think this is availible on both home and pro) and how to disable "simple file sharing" (this can only easilly be disabled on pro) but most people are only going to notice the dumbed down options in the users section of control panel (if indeed they bother creating multiple users at all).
People by and large want machines with decent performance that can run thier existing applications (Which means running windows, prefferablly the 32 bit intel versions)
AMD/GlobalFoundries has the most to lose here IMO since right now most people are running 32 bit operating systems and in any case x86-64 is an extention of x86. Intel probablly has the clout to get MS to make desktop editions of ia64 windows again if they have to.
Still intel does potentially have a lot to lose from this too and I strongly suspect this will be settled (and the exact terms of the settlement will be kept secret).
no, there just isn't the demand, especially now we have multicore. Unless you are running server tasks or some serious batch processing I doubt you would notice the difference going from four to eight or sixteen cores.
Depends on whether space is expensive for you or not.
First assuming space is not at a premium
Netbooks/nettops have atom processors with only one core, low clocks and not brilliant performance per clock. For double the price you can probablly get a desktop with a quad core processor with each core being faster than the atom in the netbook/nettop
Server hardware is way more expensive than desktop hardware per unit of CPU power. OTOH for some workloads the larger ram and caches may be a superlinear benifit.
So depending on the workload either midrange desktop hardware or midrange server harder.
If space is at a premium then you want something that will let you pack the cores densely without paying ridiculously over the odds. Probablly 1U servers with dual quad core processors.
If that was the aim (personally I doubt it) then it's pretty retarded move. Once you get beyond the really budget stuff spending a lot of extra money only buys you a little extra usefull life.
I bet he could get a machine of half the power and similar characterists for less than half the price. If we assume software bloat tracks capability at a given price point and that in turn tracks moores law than a doubling in computing power only buys you an extra 18-24 months.
More than doubling your expenditure to extend a machines usefull life from 3 to 5 years does not make sense to me.
With computers IMO it generally makes sense to buy enough to last you about 3 years and/or enough to get somewhere close to the price/performance sweet spot. Buying more than that is probablly a waste of money.
well the macbook has an output for an external monitor so it should be a simple matter of picking off the signals from there. Connectors tend to be through hole and relatively wide pitch so picking off the signals shouldn't be too hard. Probablly much easier than the soldering involved in fitting some console modchips.

Did you actually read the google whitepaper?

Looking at wikipedia ( http://en.wikipedia.org/wiki/Pilot_certification_in_the_United_States#Sport_pilot ) the requirements to get such a license don't seem that onerous. I'd imagine most people who could afford to drop $200K on a terrafugia transistion could afford the instruction needed to get a license.
Indeed, while I think flying cars like this one may find a niche. I don't think they will ever take off on a large scale.
