Comment why not just introduce LibreOffice in schools? (Score 1) 226

It's way more hackable than MS office, the kids aren't only learning how to work for one company, and they can learn to actually make their own choices. Who cares if it's actually BETTER than MSOffice or not, it's not exactly BAD software. The one thing that really can be said which stands out as superior to MSOffice is that LibreOffice is free for the kids (and parents, and teachers) to use and hack.

If you're a parent, and your're tech savvy, and you're NOT involved in your children's school's tech, then sure.. expect Microsoft will try to buy your children's futures and never expose them to the idea that they can learn their own way, with whatever tool they want.

It is now, and has always been Microsoft's way or the highway. If, in the spirit of any opensource project, you yourself don't get involved in your own kids' school, and what they use and what they can teach with, sure.. Microsoft will gladly teach your children their way only, and America will -continue- to lag behind the rest of the world technically.

Nobody gets paid to post articles about that though, Everybody's-Own-Good Corp. doesn't exist to fund this message. So alas, another comment explaining the obvious fault with this whole /. article goes unconsidered.

Very fast charge is also completely impractical for cars with any forseeable technology. To charge the (relatively small, with only a couple of hundred miles range) 85kWh Tesla battery in 1 minute would require 5.1 megawatts of power to be delivered by the charging cable. Even at 11,000 volts you'd be looking at over 460 amps to do that. The largest power station in the USA is 6800MW (Grand Coulee) and would only be able to simultaneously charge 1334 cars assuming no transmission losses.

Quick charging beyond Tesla's superchargers is never coming with current generation and transmission technology. It will require some yet to be invented technology such as room temperature superconductors and enormous fusion power stations.

It probably also demonstrates something about how energy profligate that personal motor transportation really is.

It's irrelevant if they do this anyway, because if you had a 100kWh car battery that could charge in 5 minutes, the voltage and current requirements would be so enormous to make it impractical, because you'd have to deliver 1.2MW to charge the battery in that time. At 11000 volts you'd still require a current of about 110 amps, so not only very high current, but very high voltage.

One of Britain's largest single generating plants is the Sizewell B PWR nuclear generator, rated at 1200MW. It would take just 1000 such cars all wanting to charge at once to completely use all the capacity of this entire large nuclear power station. How many cars are currently filling up with petrol in Suffolk (the county where SIzewell B is situated) right at this second? Probably well over 1000.

A conjecture could be: the big bang spawned two universes, and the sum of the parts of the two would be an equal amount of matter and antimatter, but one universe got all the matter, and the other universe going in "the other direction" ended up with all the antimatter.

You could have said the same thing about telephone 100 years ago, too, and the same thing about electricity at around the same time.

It is increasingly the case where you are excluded from participating in some parts of modern society if you don't have a decent internet connection. For instance, you're not going to be doing any MOOC courses if you don't have an internet connection that's good enough for video. You're not going to be able to find things out as easier as other people if you don't have a decent internet connection, and you can find yourself denied of many opportunities. It's not all about looking at cat photos. The internet has become embedded enough in modern society that you are now often at a disadvantage if you live in the US and don't have it, so just like the telephone became a utility, internet should also become available on a similar basis.

Unless it specifically says WiFi, it's not WiFi and not even remotely like WiFi. Most 2.4GHz radio control gear is quite different to WiFi. It doesn't use ethernet packets or the ethernet protocol, it uses modulation and packet protocols that are specifically designed for real-time radio control. Unlike WiFi it is designed purely for point to point with one end a transmitter and the other end a receiver (not bidirectional) and with only one transmitter and one receiver bound to each other at any one time. Short of jamming the entire frequency band it's not trivial to take over something like Spektrum DSMII (certainly a lot more difficult than WiFi since to bind a receiver to a transmitter requires a physical programming step using a programming 'plug').
