run a single number to back up your prejudices

How ironic that you decide to take me to task on this - a person who is actually a builder of EVs and a great believer in the benefits of an electric power-train. My point was merely that the OP's claim that petroleum-powered vehicles is the biggest source of carbon pollution is a pile of crap, as your own quoted figures demonstrate. If every car on the planet were replaced overnight by an EV, carbon pollution would not change significantly, and in any case that could never happen.

Of course EVs are the way forward for cars, and I'd love to see it - the sooner the better. But in the real world things change slowly for all sorts of reasons - technology being only one small component of that. You even make the point yourself about the "greening of the electrical supply" - which was exactly a point I was trying to make as well! By the time we're all driving EVs, other factors will be in play that complicate the picture - probably for the better. Hell, the fusion problem could be cracked by then making the whole fossil fuel vs. "alternative" argument go away.

gasoline-powered cars, which is easily the biggest source of our carbon pollution

Nope, not even close. If you want to make an argument, don't just pull crap out of your arse - it just makes you look dumb.

I do agree our addiction to fossil fuels is a huge problem, but moving to EV cars now won't make one jot of difference, because the electricity we use to charge them comes from... fossil fuels. Of course it's easier to replace fixed generating plants with alternative energy, so EV cars will get greener over time as that transition is made. But right now, buying an EV just to claim green credentials is largely an illusion.

Comment: Start Scratch (Score 1) 277

The "app" Start Scratch is a scam, in my opinion. My daughter (9) is quite keen on programming using Hopscotch on the iPad, but it is very limited at the moment. At school, she's been introduced to Scratch which can do a lot more, so I figured that it would be good to get Scratch for the iPad so she can use it at home. So I do a search on the iOS App Store and find Start Scratch, which appeared to be the Scratch environment as an iOS app. So I bought and paid the $1.49 - admittedly not a lot. But after some time trying to use it, it dawned on us that it is merely a welcome mat for the Scratch website, and not an actual programming environment at all. It's not even a good front end for the website! And it turns out that Scratch requires Flash, so it can not actually be used with the iPad or any iOS device at all. Totally and completely useless.

I didn't complain because I felt it was as much my own fault for assuming that the app did something useful, since Scratch is otherwise a trustworthy name. Fool me once...

Windows had a colour graphics API; the Macs of the period were still black and white

Nope. Colour Quickdraw was written in 1985 and shipped with the first Mac II in 1986. It had a full colour RGB model, though initially only had 256 colour hardware - 32-bit hardware came in 1987. Even the original "black-and-white" Quickdraw had a simple colour model to support colour printing on Apple's dot-matrix printer.

You could also do colour graphics on a C64, BBC Micro and ZX Spectrum (hint - the name "Spectrum" was for that very reason). Rewrite history all you like - some might even believe it - but there are plenty of us still around that actually remember how it was.

the user interface needs to compete

No. A thousand times no. The UI of in-car equipment must not compete in any way for the driver's attention. A good UI would require no sight at all, but would provide a consistent placement, easy to find without taking your eyes off the key task you have as a driver - driving, provide consistent and non-visual feedback, and work 100% reliably every time. Ladies and Gentlemen, I give you... the "switch".

Point is though, that an airship (or any aircraft) is only actually useful if it makes some progress OVER THE GROUND. So sure, it doesn't need more power to maintain a particular airspeed, put it does to actually get somewhere in a headwind. And with that huge frontal area, that's a lot of drag to overcome.

Most people seem to focus on the safety of airships, in the light of the Hindenburg, R101, etc. Surely a more significant problem is the wind? Any amount of wind is going to make landing and takeoff hazardous, and making much headway against a strong headwind is going to take a lot of power with that much windage. Good luck to them, maybe there are enough fair-weather opportunities to make it pay, but this aspect is seemingly never discussed.

Comment: MRSA != Golden Staph (Score 4, Informative) 124

by GrahamCox (#49382495) Attached to: Thousand-Year-Old Eye Salve Kills MRSA
Staphylococcus Aureus, aka "Golden staph" is not exactly synonymous with MRSA. The MR part means 'Methicillin Resistant', which is a mutated form of SA that can't be killed with Methicillin, a common antibiotic. SA is extremely common - it's everywhere, all over your skin, right now. It's only dangerous if it starts to infect a wound and gets into the bloodstream. Most SA will still respond to antibiotics, only the MRSA strain won't. But this strain is still thankfully fairly rare, though it's a growing problem. One solution would be for everyone to stop taking antibiotics for minor ailments such as the common cold which it does nothing for, but adds a lot of unnecessary antibiotics to the environment, thus prompting common bacteria such as SA to evolve into the MRSA form. If we lose the benefit of antibiotics, it will be a disaster, and we can thank all the stupid people for that.
