  1. Re:Not art on 3D-Printed Gun Bought and Displayed By London Art Museum · · Score: 2

    The Imperial War Museum (also in London) has three Gyrojets in its collection: http://www.iwm.org.uk/search/global?query=gyrojet&x=0&y=0 .

    But they don't seem to be interesting for their artistic design, which is what the V&A collects and exhibits.

    I bet nowadays kids get expelled for that, at a minimum.

    After the teacher found out, I got banned from using the school computers for the "rest of the year", which was about five days. I think the fresh air and sunshine probably did me some good. That was 1997.

    (I didn't access any teacher's account or files. It was Windows 3.1, the "hack" was making a macro in word to open File Manager, then opening "progmana.exe", which was a copy/configuration(?) of Program Manager with the administration programs. I was 10, all I wanted to do was change the colours and the wallpaper.)

  3. Re:Much better on Is It Time to Replace Your First HDTV? (Video) · · Score: 4, Informative

    My new 42" LED backlit screen consumes about 1/3rd the power (50-60W vs 140-150) of my first generation 1080p LCD, it also looks better. I probably wouldn't have upgraded if it hadn't been for a ghosting artifact caused by my HTPC menu getting burned in on the old one but now I couldn't imagine going back.

    With a delta of less than 100w it will take you a lot of TV watching to come close to a break even on cost from the efficiency gain (say, 30 _thousand_ hours if you spent $350 on your tv). Efficiency is a good thing, but it is important to know the context.

    Americans average 34hrs/week watching TV, so it would take 16 years (less, assuming electricity costs decrease).

    British people watch less, 28hrs/week, but electricity costs more (average £0.145/kWh), so a TV costing £250 and saving 100W would take almost 12 years to pay for the saving.

    My plasma TV's consuming ~350W now, with a dark sci-fi film (brighter scenes use more power for a plasma TV). The saving here would be greater: about 5 years to pay for, less since we don't just watch dark films.

  4. Re:even old/cheap tvs are great on Is It Time to Replace Your First HDTV? (Video) · · Score: 1

    We have an "old" TV, given to us by someone that upgraded. I think it's HD resolution, but it doesn't do HDMI etc.

    It's a plasma screen, and the watt-meter I have measures about 300-600W consumption depending on how bright the scene is -- it's usually about 400-500W. If I used it more than once a week I'd be more interested in upgrading it, but I don't.

    If I used it as much as the woman next door uses hers, an upgrade to an LCD TV would pay for itself within a year in reduced electricity bills.

    If you're somehow telling it what track it's on, you may as well use that system to tell it what the speed limit is -- which is what the European signalling systems do already.

  6. Re:TFA from Wired on Japan's L-Zero Maglev Train Reaches 310 mph In Trials · · Score: 1

    No, that's no problem. The problem was not installing/using a suitable signalling system, which is present on high-speed lines in most other countries.

    It seems to me that it would have been (and still is) possible to include a GPS receiver, a maximum-train-speeds database, and a speed-limiter on each train as a fallback. With that, as long as the GPS was working, even the dumbest/craziest engineer would not be able to make the train go faster than its maximum specified speed at any given location.

    GPS wouldn't work in tunnels, and very often higher speed lines are adjacent to lower speed lines. here's an example, which I used to walk past sometimes. The fast lines have a 110mph limit, the "slow" lines 70mph, and the siding for a factory 20mph. The tracks are about 4-6m apart. Also, the maximum safe speed is much lower if there's a train ahead on the line -- the capacity of the line is much reduced if you have to enforce 10km distance at all times.

    There are very safe signalling systems, like The TGV signalling system and ETCS. However, it seems they didn't properly implement the transition from high-speed to normal line in Spain. I don't know if that's a lack of investment, a lack of regulation, or a technical oversight.

    The Vietnamese used to write using Chinese (Han) characters, but switched to Roman letters. It wasn't their culture though, so I don't think they had much attachment.

    In China, one person I asked to read something said they "couldn't read the font", but I /think/ that was just an excuse to avoid talking to me.

    I don't know how realistic your example is -- I'm sure it could happen, but I don't know how "stupid" the boy would need to be. Would 99% of 15 year olds have managed, or only 80%? I have an app on my phone that can do reliable, accurate OCR of the characters (Pleco), from touch or camera input, so it won't be too long before "stupid" people don't need to remember the rarer/harder characters. (The app is great for reading restaurant menus.)

    The recent Spanish high-speed train "accident" was a disaster waiting to happen when you study it, there is no way a high-speed railway line should have had an 80kph-limit curve like that anywhere along its length.

    No, that's no problem. The problem was not installing/using a suitable signalling system, which is present on high-speed lines in most other countries.

    (I don't make a habit of remembering the speed limits of curves, but IIRC the speed limit through the Channel Tunnel is 100km/h.)

  15. Re:Ryanair dreams of just being horrendous. on Angry Customer Buys Promoted Tweets To Bash British Airways · · Score: 1

    I would never fly Ryanair, because my understanding is that if there's ever any problem, even if it's entirely their fault, their first and only reaction is going to be flipping you the bird, and I don't want to rist that.

    That's what they'd like to do, and they will indeed do little more than the minimum they're legally required to do (so if you didn't book a round trip, but only a flight home, they may well just refund you in full and you'll have to buy an expensive ticket at short notice -- probably with Ryanair). However, they are one of (if not the) most reliable airlines in Europe, mostly because they fly to tiny airports that no other flights use. There's much less chance for something to go wrong.

    The experience on the plane has become worse every year I've used it -- it's worse than a suburban train, they play several advertising jingles on a flight now -- but when I go to eastern Europe having a relaxing journey to/in a tiny airport, and landing exactly on time in England, for less money, can be preferable to the inevitable delay of Heathrow.

    Some airlines now charge for a "large" cabin bag, e.g. http://wizzair.com/en-GB/useful_information/service_fees -- but I don't think this is unreasonable, since far too many people were taking maximum-sized bags. It really slows down boarding when there's no room for all the cabin luggage.
