In England the subway arrives from right to left, not form left to right. For the simple case of a two track line with platforms each side that is correct. Not all stations are layed out like that though so generally it's better to follow the signs;).
I was under the impression that Canadians liked paying taxes. Speaking as a brit it's not so much the tax per-se (I mean it's a pain but no more so than getting hit with the VAT at the checkout when you shop as a private customer at a mostly B2B site) as the fact that the courior companies use the customs brokerage and collection of the tax as an excuse for slapping on a somewhat hidden* extra fee to international shipments.
At least in the UK when ordering internationally it is better to specify that things be sent through the postal service if possible. In the UK the post offices brokerage fee is not too steep, lower value packages get an exemption and many higher value packages seem to slip through the net.
*it is often very difficult to find out what the fees for a purchase will be before actually receiving it and most online suppliers don't even make it particually clear that such fees are likely.
foreseeable means that something can be forseen, not that it was/is forseen. Just because a forecast is possible doesn't mean anyone bothered to do the calculations and research needed to make that forecast.
It's kind of like the difference between "knew" and "should have known"
The first is it reduces the latency when two forward bases want to communicate with each other.
The second is that it means your forward bases can communicate with each other even if your main base is somehow knocked out.
The third is it reduces the load on the downlink to main base.
Of course there are trade-offs to smart satellites, you can't use more complex modulation to get more out of an existing channel for example but you can't easily do that anyway if your satellite is serving lots of ground stations and we are getting pretty close to the limit on modulation efficiency anyway. So I think your "obsolete in two years" is overstating the case severely.
1: transport direct is useful for intermodal planning but it also seems to show incrediblly slow coach routes sometimes even when there is a much faster rail route which can get annoying. Rail specific planners areg enerally easiler for rail planning in my experiance.
2: get the timetables for the routes the planner sends you on, this both lets you avoid routes with unacceptablly low frequencies and helps you replan when trains are delayed. Sometimes if you are quick at changing and have open tickets you can even get there sooner than the planner says.
One or two changes should not pose a problem. More might get tedious. I tend to worry more about total time and potential time extentions than changes, indeed in some ways i'd rather have a few changes than sit on one train for hours.
One nice thing about basing yourself in london is that being the hub of the UK rail netwosk a lot of places are in day trip reach by train. hell london to manchester is only just over two hours.
ring some really good walking shoes. Public transport in london is expensive and crowded On that note if you are going to use public transport in london get yourself an oyster card, fares on oyster are generally lower than paper tickets and they have a nice feature called daily price capping which "automatically calculates the cheapest fare for all the journeys you make in a single day".
You're right on the power supply. Just pick up an international adapter kit and you'd be good to go. Most modern electronics are 120-240 50-60Hz. Still it's a good idea to check.
check overflow, if so add 1 to B or D, then add B + D store in D Most CPUs have an "add with carry" instruction that reduces this sequence of steps to one instruction.
Faking higher-precision floating point in lower-precision hardware is WORSE. Agreed, FAR worse.
In summary firsly use a LCD screen, this pretty much eliminates emmisions from the display itself but the link to the display is still be an issue. Countermeasures against link snooping can include messing with foreground and background colours, adding noise or best of all using an encrypted (e.g. HDCP) digital link.
You obviously haven't read the rest of my posts on this subject; specifically the one where I address this using Amazon and Jeff Bezos as an example. Your original post: It looks like there is a root flaw in your logic implementation there jbacon. You are right about the special casing needs, but a simple redirection to a page explaining that they are using a non-standards compliant virus sink with links to getfirefox.com Read in the context of the post you were replying strongly implies that you were reccomending this is a course of action to ordinary web developers. Along with most of the others replying to you I believe such an action would be pretty close to suicidal for any business operating on-line.
When someone pointed this out you responded by moving the goalposts: You're really not getting this concept at all, are you? When the user went to B&N, same thing. Amazon? Same thing. If you could get all the major online supplier to do it at the same time then I accept that they might make some headway. However I think the chances of them colluding like that are pretty low given they have no real business reason to do so, the large risks if someone breaks ranks and the fact that even if it was successful it would likely cause a lot of delay to customers.
The users that are doing legitimate business will file a ticket against the issue. Of course there are a lot of websites that people use at work a lot but not for work related purposes. Slashdot would be an example of such a site.
Even if the user is doing legitimate business stuff do you think they are more likely to try and fight the bureaucracy and if they win maybe come back and order something from you months later or just move on and get what they need somewhere else?
The only way such an act could work is if a large number of large websites got together and did it at the same time. Something I doubt would happen.
Vista and will be supported until Vista ceases to be; contrary to what others may say, this is likely to be a very long time, I'd wager a minimum of 1 decade from RTM. Your wager would appear to be correct for vista business and enterprise their current plan seems to be a decade and a few months from "general availability" http://support.microsoft.com/lifecycle/?p1=11707 . I doubt they will reduce the dates but they may pull what they pulled with XP recently and claim some fixes are impractical to backport.
Given how unpopular vista has been in the enterprise I doubt these dates will be extended (unlike 2K and XP which got a lot of extensions over their lifetime).
The other editions of vista (home basic, home premium and ultimate) are currently listed as not getting extended support presumably because they are considered consumer products. how exactly that will play out remains to be seen (my guess is they will be able to download patches for the core OS but the home specific media stuff will cease to be updated).
Isn't IE5, like, you know, very old? MMM but according to MS 5.01 SP2, 5.01 SP3 and 5.01 SP4 on win2K are all still supported.
What I find really odd is that according to MS 5.01 is still supported (and three different service packs of it at that) but 5.5 isn't.
But, one of my excuses for sticking with IE6 (and my reason for posting anonymously), is that I can't go past IE6 with Windows XP Pro SP1. And no, I will not install SP2, since it breaks programs. It did though it was all so long ago that i'd expect most of them to be fixed by now unless you rely on some strange legacy shit.
Bear in mind that internet explorer life cycles are tied to the underlying version of windows, so while IE6 on XP SP2 and SP3 is still supported IE6 on XP SP1 isn't so you may miss out on some security updates.
BTW win2K SP4 is still getting security updates (though not for much longer) so a fully up to date win2K box should have less holes than a fully up to date XP SP1 box. If you really rely on stuff that breaks with XP SP2 then 2K SP4 may be a better choice.
Why not two drives....your performance drive, OS, shared libraries, commonly accessed software and files on super fast SSD. Ok for desktop users but most laptops either can't accomodate two drives full stop or require some other significant component (often the optical drive afaict) to be sacrificed to get a second drive.
Squaretrade claim to have only included new purchases in this survey.
Also thier definition of netbook is based on price alone, some very cheap craptops may sneak into the netbook category while the high end netbooks that have started appearing on the market would be lumped in with the low end notebooks.
The thing is unless your house is HUGE a huge CRT isn't very practical. LCDs and plasmas OTOH can be wall mounted and therefore take up much less space for a given screen size.
I'm in the uk where afacit our rooms are smaller than is typical in the USA but until recently 30 inch would have been considered very big for a TV (living room TVs were usually somewhere in the low 20s) but all the big box stores are now pushing massive TVs.
And then there is the whole widescreen thing, at least until recently (it seems to be slowly changing now) the extra space at the side of a widescreen was mostly filled with fluff so to get the important parts of the picture at the same size on your new widescreen it needs to be bigger.
Afaict microsofts soloution seems to be to pepper thier netbook version of win7 with annoyances. no aero, no multimonitor, no fast user switching, no multitouch, no media center no user changable wallpaper. Functionally this will make it worse than the XP that netbooks come with at the moment.
I guess they are hoping to sell the netbooks cheap first and then sell anytime upgrades to home premium later.
Still it's relatively mild really, only buildings on low lying land are hit and even those that are hit usually just need cleaning up and refurnishing of the ground floor.
I mean it sucks for those who were too stupid to make sure the house they bought wasn't on a flood plain but for the rest of us it's not really a huge deal.
So many people used the javax.swing library before it was officially released that they chose not to change the "javax" to "java" I'm pretty sure swing was officially released as a seperate package before it's integration in java. It was put in "javax." rather than "java." so that applets could download and use the seperate swing package within the sandbox (sandboxed code can't load it's own classes in "java." )
At least that is what I remember reading in books produced at the time.

12 years is long enough to be a PITA, according to wikipedia that means you need 18 tons of tritium in storage for every ton of helium 3 production.
And of course you have to make the tritium in the first place.
Close but not the same,
foreseeable means that something can be forseen, not that it was/is forseen. Just because a forecast is possible doesn't mean anyone bothered to do the calculations and research needed to make that forecast.
It's kind of like the difference between "knew" and "should have known"
I was under the impression that He3 was so rare in natural helium and/or so hard to extract from it that separating it out was not considered viable.
The main source of He3 is as a by-product of the use of tritium in nuclear weapons.
... latency is gonna be a bitch. Guess they're dealing with that in satcom already, though, right?
Right
Which if you have multiple bases in the field (call them A and B) that want to communicate with each other is a bloody good reason to route in space.
A-sat based router-B is going to be a lot lower latency than A-dumb sat-Ground based router-dumb stat-B.
I see a few advantages to this
The first is it reduces the latency when two forward bases want to communicate with each other.
The second is that it means your forward bases can communicate with each other even if your main base is somehow knocked out.
The third is it reduces the load on the downlink to main base.

I disagree. Get http://transportdirect.info/ [transportdirect.info] to plan your journey.
A couple of points
1: transport direct is useful for intermodal planning but it also seems to show incrediblly slow coach routes sometimes even when there is a much faster rail route which can get annoying. Rail specific planners areg enerally easiler for rail planning in my experiance.

someone else linked http://www.cl.cam.ac.uk/~mgk25/pet2004-fpd.pdf which gives some countermeasures.
In summary firsly use a LCD screen, this pretty much eliminates emmisions from the display itself but the link to the display is still be an issue. Countermeasures against link snooping can include messing with foreground and background colours, adding noise or best of all using an encrypted (e.g. HDCP) digital link.
I suspect there is already an encrypted standard for digital monitor signals
The paper that the GP linked suggests using HDCP.
