The three laws of robotics come from Asimov. Clarke's three laws are:
  1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
  2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
  3. Any sufficiently advanced technology is indistinguishable from magic.

Meetings are for things where you need realtime discussion and free-flow of ideas. They're good for working through problems (as long as they're sufficiently small) with a whiteboard and then photographing the board for archiving. They're absolutely terrible for status updates and so on, which are effectively broadcast communication.

I subscribe to the theory of natural selection when it comes to clothes. The purpose of the washing machine is to supply evolutionary pressure. Clothes that don't survive die off and don't reproduce (i.e. I don't buy similar ones in the future). Eventually my wardrobe is full of clothes that are fit for their environment. The same applies to crockery and the dishwasher.

Weather is a chaotic system, but often chaotic systems have longer-term trends that are possible to observe. For example, if you pour sand into a pile, then you can fairly accurately predict the shape of the cone that it will create, but the exact pattern of bounces for each grain is impossible to predict as it depends on the exact position, shape, and location of every grain that it hits on the way down and a tiny error in any of these will magnify to a huge error after a few bounces. It's a chaotic system that has macro-scale effects that can be predicted.

Weather is a chaotic system with very similar properties. The longer the timescale, the easier it is to predict. Predicting the average temperature difference between summer and winter, for example, is much easier than predicting the temperature tomorrow.

To give a simpler example, if I toss a coin 100 times, I'd expect you to be able to tell me, with a fairly small margin of error, how many times I will roll heads. I wouldn't expect you to be able to guess what the result of any individual toss will be more than about half the time.

If you think that predicting weather and predicting climate are similar problems, then I'd encourage you to read up a bit on chaos theory.

The whole reason Firefox exists is because a group broke off and built it to remove the feature bloat in Mozilla/Netscape.

The 'feature bloat' that they removed was sharing a XUL / XPCOM runtime with the mail client and other apps. If you only ran the web browser, Firefox was lighter, but if you also used the mail client then Firefox and Thunderbird were heavier between them than the old Mozilla suite. The main reason that I switched back in the day was that the browser was very crashy and I'd lose in-progress emails when the browser crashed: moving the mail client to a separate process fixed this.

There have been a few proposals recently to abolish SIMs. They were created back in the days of rented carphones so that people could move their phone number and contacts between phones easily. Now, they basically serve the same purpose as a WiFi password. It wouldn't be too difficult to provide the keying material in a QR code or similar so that when you get a new phone you just photograph it and have an app provide it to the baseband processor.

Carriers are very hostile to this, because if the SIM isn't a physical device there's no constraint on the number that can exist in one phone - you could easily have an app that would select the best rate from a dozen or so pre-pay virtual sims for whatever country you happened to be in.

Nuclear is expensive. http://www.lazard.com/PDF/Leve... Look at page 11.

Page 11 is talking about capital cost. The figure for nuclear is $7,591/kW, which is a lot more than some (although not the highest). But how does that work out over the lifetime of the plant? Assuming 100% uptime, that's 8,760kWh in the first year, so that's less than $0.90/kWh. If the plant is operating for 20 years, then that's around 4/kWh. Most nuclear plants are built with a 40-60 year expected lifespan, which makes the capital cost negligible over the lifetime of the plant.

The correct page to look at is Page 2, which gives the unsubsidised cost of electricity from all of the generating mechanisms. Nuclear is $124/MWh - that's lower than all of the other fuel sources in their 'conventional' bucket that have a little representative diamond listed (coal doesn't, and has a range that extends both above and below nuclear). Only Gas Combined Cycle is cheaper on average, and that's only when excluding most of the costs. Only utility-scale PV comes out cheaper overall, and you also need to add in storage costs if you want to use PV for a significant amount of grid supply.

You're better off building a containment wall against flooding and keeping the reactor not too far above the water level.

That's fine too. The problem is building neither. The other problem is not fixing the design that was known to cause hydrogen build-up and explosions that breach containment in any problem scenario.

For every anecdote of a human taking over and saving the day, you can find a similar one of the human taking over and crashing. It mostly boils down to the amount of training that the pilot has had - and even the ones that end up crashing in situations where the automatic systems would probably have managed have had vastly more training than almost any driver on the road...

Comment Re:If "yes," then it's not self-driving (Score 2) 362

It's worth noting that there is one piece of automation in cars already that does give a different kind of driving license in a lot of places: automatic gear change. If you get a driving license in a car that has an automatic transmission then you can't drive manual cars with it, though the converse is allowed.
