It's wind resistance, it makes a massive difference. When they're really far apart the rear driver is just driving better and shaving time off the lead, so he catches up, but once there it's down to drafting to get the little burst of speed to get alongside. The carts are probably approximately equal in power, so he reaches level from the draft position easily enough, but can't keep the momentum to get a lead with the new air resistance on him, just draw level. So they're level, but obviously there's only one sweet racing line to take to keep your speed up and lap time down. You can either pass on the outside (in which case you have to go faster into the turn to stay ahead) or the inside (in which case you have to turn sharper at speed to stay ahead) both of which are risky, or you can return safely to the racing line - i.e. not by swerving into him, but by conceding the lead to him and dropping in behind him. If you do that, you take less risk and give yourself the chance to try again because you're in draft position again. He needs to stay as close as he can and find the right place to overtake so that his superior driving can give him the lead into the racing line of the next corner, at which point he gets right of way and the position advantage the lead gives. Sometimes that's not even possible and lead to what some would call boring races (Monaco Grand Prix) where the leader is decided on the first corner and doesn't change unless they crash out.

I'll draw two parallels:
1. DRS in F1 racing, where a tiny part of the tail opens up for a small part of the track, which drastically increases speed and allows for more interesting races because it almost ensures overtaking. You can also see the same application of the racing line and people conceding position or trying to take different lines and spinning out or locking up.
2. In cycling, the commonly quoted figure is that you can save 40% of your energy by drafting behind a leading cyclist. The Tour de France and every other cycling road race is defined by drafting, cos no lone cyclist would ever be able to keep pace with the peloton which 'cycles' riders in and out of the wind-protected bunch throughout a day. This should convince you more as cyclists are not streamlined objects but still offer significant gains. Go and watch a cycling sprint finish - it's a case of whoever gets behind the fastest guy wins by conserving energy in his wake until it's time to burst out alongside and pass.

You can go way faster when you aren't fighting wind resistance, the closer you get to someone the faster you can accelerate towards them, but the moment you try passing, you get the full force of the wind on you, and you lose speed. So could have been the other cart had more power, or could be the driver filming this was bigger/heavier.

The theory can still work, though. Rather than relocating a cart, imagine it's a new restaurant opening. That new restaurant sucks up a lot of the business of one of the prior restaurants. The prior restaurant goes out of business and the cycle starts again, repeating until there are no better locations to open new restaurants.

...This is a terrible explanation, You're comparing two guys with movable carts to buildings, which are.. slightly harder to move.

It explains why the two vendors would eventually be close together, yes, but if you're in a city where you have one spot where you can set up shop forever, then your choice becomes a little more complex.

One of the easier solutions to the question, and the one that I personally find more viable (especially as I work in a restaurant that's close to 3 others) is that people don't like to wait.

If you have your restaurant out in the middle of town, and you get a full dining room within the first hour of dinner service, you may go on an hour long wait. The thing is though, how many people will say "Well, it's going to be an hour, lets sit outside." vs "Well, it's going to be an hour, lets go try somewhere else." Because I'm relatively sure the latter happens more often, especially if there's another place 5-10 minutes up the road.

If, however, you have 3 restaurants all located near each other, the likelyhood of all 3 filling up at exactly the same time is small. Here's the thing though, once you fill up that first restaurant (we'll call it A) restaurant B and C will start to get overflow.

Now it seems like i've defeated my own point, but now, you have 2 more options that are less than a minute away. People will either A) try to go to either B or C, or B) Sit and wait, because they can see the parking lot for those two restaurants are also pretty full.

B) retains more business, and if they choose A) The wheel continues to spin for whichever restaurant fills up first. A fills, B and C get overflow. C fills, B and A get it.

It's a system that actually benefits everyone involved because you'll also likely increase the amount of people you'd have coming to your business just because people know that's where a cluster of restaurants is.

In the long run, it's just a mutually beneficial set up.

I re(member/call) when my huge CRT monitor went bonker when one/1 of the work people brought in a cart near my cubicle. I think there were magnets in it.

Their selling point for W8 and attempt to compete with Apple's iPad was meant to be unity between desktop and tablet, but that was always a pipe dream. They put the cart before the horse by forcing Metro on people before there was any semblance of a mobile app base so it simply became a nuisance.

A mobile interface should have always been adapted into the standard Windows UI, rather than existing as a separate entity with separate complimentary versions of IE, media players. They seem be trying to bridge the two together in W10 but I think it's too little too late.

Realistically though tablets are largely about consumption, the issue was that this was forced on desktop. I mean sure, I've seen the Surface make a great note taking device (any large Wacom tablet would do this great), but beyond that? I mean the idea of doing anything beyond basic Word let alone Excel/Access work on a tablet is farcical.

Clicking manage literally does nothing, lol. But thanks. To be fair, I have modified W8.1 quite a lot (e.g. bringing back start menu) but I did the same with W7 and never had such problems.

I think he needed to wait around until she PAID for that juice/milk...then dump it on them both.
I can't stand parents like that. Her poor child is going to be in jail fairly soon, since no one (beyond a stranger) will tell him hitting is wrong, especially with a weapon like a shopping cart.

What is Islam? Who or what are Muslims?

It seems every single debate over whether Islam is a religion of peace or of violence comes down to this same argument over who or what defines those terms and there is never an agreement. Indeed, much of the conflict in the middle east is due to followers of Islam arguing over who's particular interpretation is correct. Meanwhile in the western world religion is something that, as the late Hitchens put it, we take "a la carte". It seems you can no more describe a person by revealing their particular faith than you could describe what food you had last night by giving somebody the whole menu to the restaurant. You might ascertain that it was perhaps Thai food... but little else.

Still though, when we go the texts we do find quite unequivocally immoral preachings. I think the religious really have to find an answer for this. We aren't buying the alternate interpretations or the lost in translation theories. When you describe yourself as a Muslim or as a Christian, or as any other faith, it seems to me you don't really have much of a right to get upset when we call you on the evil shit in your holy books. You might protest that you are not that "kind" of Christian, but the speed at which you dismiss any given passage is only matched by the speed at which you declare divine truth for another. We understand the vast plurality of beliefs, which is why it baffles us that you subscribe to a particularly narrow set of ideals whilst simultaneously admonishing us for tarring you all with the same brush.

When your shopping cart is running wild, don't trap it. Try to let it run off and calm down on it's own.

No, this is police theft under the guise of 'regulation'. Actual regulation would regulate when they can seize, not give carte blanche to steal any money they find and require the victim to 'prove' their money isn't suspect. That's a lack of regulation along with immunity granted for institutional theft.
Once again, (reiterating because of your repeatedly and recently displayed lack of comprehension) cops are at their discretion to seize, and they repeatedly and constantly abuse that power, meaning they need to be regulated. Government regulation can mean regulating the government...but that's a concept that escapes you.
Cops (and their 'conservative' lawyer buddies) wrote this law and lobbied to have it instated....proof that sometimes cops do make the law AND abuse it. Prison guards have the largest, best funded, biggest lobbying union in the US, they're cops, and they've written many laws.

The tank mods are added by retailers and print shops. You're right about how the system works -- the lines run from the big tanks and are inserted through a hole drilled into the carts small reservoir.

One issue with that is that most cartridges have a software page count that is used to tell you that the ink is running low / empty after a certain number of prints. So, along with the tank install, most shops will put in an aftermarket chip or PCB that resets or bypasses that counter.

For the other question, I think that Thailand still relies on printed documents more than in the US, but it is going down. I undoubtedly have a somewhat skewed opinion on things since I am a teacher, though. I teach 18 different classes of roughly 40 kids once a week, with a worksheet or some other printout being used nearly every week -- so I probably burn 700+ pages each week through my school's copy machines. Then I teach smaller private classes at home, with maybe 100 or so pages a week on my own printer(s). I have one inkjet with those tanks installed, 2 mono lasers, and 1 color laser... So yeah, I probably am a much heavier user of printed stuff than your average person.

I think I'd have to see it in actual printed form to judge the readability accurately.

BUT, in terms of readability on a display, like the 40" 1920x1080 LCD I'm watching on ... it is quite poor in my opinion. I have a feeling that it would work much better in ink on paper.

33% ink savings sounds pretty good, assuming that the readability on paper is better than a display. That being said, encouraging printer manufacturers to have a more sane approach to refillable ink/toner reservoirs would have a better/bigger impact.

Here in Thailand, where respect for patents / IP is low, (SE Asia is notorious for fake manufactured goods, pirated "soft" media, and hardware hacks / bypasses) I'd guess that around 90% of inkjet printers sold have a tank system glued onto the side with ink lines running into the cartridges from big CYMK reservoirs. I never buy new cartridges unless the print head gets damaged/worn out -- instead, I just buy cheap LARGE bottles of the different ink colors and refill the reservoirs. (Image link of such a setup HERE)

That kind of mod would be a gray or black-market item in the West, but here the laissez-faire attitude about such things has some positive effects. At least, for a consumer (like me), or someone concerned about the environmental impact of all the waste packaging for ink carts (like the dude in this video).

Perks? Basements? Hey Futurama, you live in the U.S.?? How about you and 70 million Americans miss a month of paychecks and commandeer yourself a grocery cart and join the ranks of the nuevo-homeless? Maybe you can find bed or back-down at one of these places...Moron much??
