Which is fine if you want each half-wall to be a slightly different tint of blue.

Then you "box" the paint. Pick up sufficient paint to do the whole job, and if they are in several smaller tins you simply mix them all together in one big pail. Return to the smaller tins for convenience (certainly at least one tin, for later touch-ups).

Even when buying new, if you are obtaining several tins of the supposedly-same shade you should still box them.

> I just hope that Aotearoa remains a bastion of pacific sanity.
Sadly the writing is on the wall. We (NZ) used to have the stones to stand up for ourselves on the international stage, but our current Prime Minister just wants to please everyone and I can't see him saying No to increased pressure from the States - he'd much rather smile and get Obama's handshake on his résumé. We've already brought in a guilty-till-proven-innocent three-strikes law for filesharing - that was completely embarrassing to see our politicians demonstrate a complete lack of grasp on the issue.

Australia and the USA are our #1 and #2 export markets so we tend to succumb when they start tightening the screws.

Full-body scanners are currently illegal in NZ, but I'm not sure if that only applies to nudie ones (it might be this aspect which makes them illegal; I'm not sure). I fear it's only a matter of time before that piece of legislation gets removed, or some loophole is found to bring two half-body scanners in - one for the upper body immediately followed by one for the lower half...

Comment Re:I miss GOTO...there I said it (Score 1) 353

so some number of operations need to be done in order, and if any of them fail then they need to be undone in reverse order... if you don't consider the comma operator to be unconvoluted (it's a bit obscure, I'll give you that) - and know how the && operator "aborts" when an operand is found to be false (*everyone* should know this) then:

int level = 0;

if ((++level, do_op1()) &&
    (++level, do_op2()) &&
    (++level, do_op3()) &&
    (++level, do_op4()))  // value of "level" will be equal to the number of the operation currently being attempted
{
  return 0;
}

// at this point, value of "level" will be equal to the number of the operation that failed

switch (level) // note the lack of "break"
{
  case 4:
    undo_op4();
  case 3:
    undo_op3();
  case 2:
    undo_op2();
  case 1:
    undo_op1();
}
return -1;

Comment Fitted in New Zealand since August (Score 4, Informative) 235

They've been compulsorily fitted to taxis in New Zealand since August. Taxi companies fitted them at their own expense. Drivers are saying they feel safer, and the industry is claiming the amount of abuse against drivers have dropped and the cameras have directly led to arrests, including for several very serious incidents. Despite the camera systems costing upwards of $1000 per vehicle, the drivers are saying it's money well-spent.

So please ignore the cynicism of the Slashdot submitter & editor - they evidently do improve driver safety.

Because using the extension to determine what a file does was characteristic of MS-DOS. So the "C:\" part of that line isn't the only MS-DOSism present in that line, as Unix-like systems use permissions to determine if a file is executable or not rather than the extension.

Comment Re:Charge time. (Score 2) 241

For a race car you could use ultracapacitors instead of batteries. How much current can your charge cable handle...?

Not realistic with current capacitor tech. At best, caps can currently store about 1/5th of the capacity of a battery of similar mass. The best production ultracaps are around 30Wh/kg, whereas LiPo batteries are well over 100Wh/kg, and can exceed 200Wh/kg for certain variants.

Comment Re:L/100km? (Score 1) 417

Well, it's not efficiency for starters, it's efficacy. And "output"/"input" is all a matter of perspective: I don't put a fixed amount of fuel in my car and then want to know how far I can drive. I know how far I must drive, so L/100km gives me consumption and therefore fuel cost of my commute. Hence I can readily estimate weekly, monthly, or yearly fuel cost.

It's also linear: 12L/100km is 20% worse than 10L/100km, and 8L/100km is 20% better, for a known distance that needs to be travelled. 8.33km/L -> 10km/L -> 12.5km/L is not linear. Whether you prefer a linear-proportional scale or inversely-proportional scale in this matter is up to you.

Consider that distance travelled is fixed (it is for me) and therefore distance is the "input", and fuel consumption (or cost) is the "output" - albeit a negative output - and then it makes perfect sense.

You might want to check where the Mazda3 MPS sits on the Nurburgring lap times. Look closely at the company it keeps. It's right between Corvette C5, Honda S2000, Honda NSX and Lotus Exige. It's faster than the MX5 (by 1 second) and the RX8 (by 4 seconds). The Mazda3 MPS is currently Mazda's fastest production model - despite being FWD. It's stopping distance (60-0mph or 70-0mph) is also exceptionally short, and comparable to many supercars. Look it up.
