    I did, the article is wrong and idiotic. Here's the EU press release:

    Member States approve the phasing-out of incan-descent bulbs by 2012

    100w blubs are not banned, they are to be phased out by 2012, with the details of the phase-out to be determined by member states as they choose.

    As in, you sell it, you go to jail.

    No they didn't. Check your sources.

    The EU has mandated a phaseout by 2012, it's up to member states how they implement that. In the UK, for example, the government and retailers are working together on a voluntary programme.

    You can make a comparison with the regulation of fridge and freezer power consumption a few years ago. The EU put limits on how much power they could draw (banning the lest efficient types) and required that fridges and freezers should display their power consumption band (A for very efficient, F for terrible) prominently in the showroom.

    People love having numbers to compare when chosing between products, so they now very much favour efficient models. Manufacturers are competing to get better efficiency ratings, something that wasn't given that high a priority in the past. Notice that the US benefits too, since these new efficient models are sold there as well. Thanks to EU regulation, you now have much more efficient fridges.

    As a result, the consumer wins. For almost no effort (just a little light regulation) we now have much more efficient appliances, a noticeable reduction in our energy bills, and a drop in national CO2 output.

    What's happening here is the same thing, but with TVs. You can expect this type of regulation to spread to other electrical appliances in time. And it's been such a success I can see the US picking up this type of regulation as well.

  7. that's not how X works on Wayland, a New X Server For Linux · · Score: 2, Informative

    Sorry, you are totally wrong, that's not how X11 works at all.

    The client queues up a set of drawing commands (not bitmaps), at some point the queue gets flushed, and for a local display there's a context switch and the server updates the screen. This is exactly how Windows and OS X work as well. The only difference is that the X11 protocol was carefully designed to be asynchronous, so that when you run over a network connection rather than locally, you don't get killed by latency on round trips.

    Browser apps are nice in many ways, but that's a separate issue from the display architecture.

    Bad things about X11: primitive drawing model, too much hardware management (this is an X.org problem rather than an X11 one, really), a lot of legacy. Most of the things that are actually bad are being or have been fixed.

    The PC electronics only burns 1-2 watts in standby, but the large and idle power supply will burn another 8 or so.

    Or at least that's the way my imac is. I got a watt meter and it's 70w at full power, 40w in low-power mode, 10w in standby and 10w when off. It only goes to zero when you unplug it.

    Awesome, so all malware needs to do is stay resident as the user's process until it detects that the user has elevated privileges. Then BLAMMO, sudo rootme.

    No, that one process gets a temporary elevation, not the user. It's not a security hole.

    Windows dev friends tell me that Windows actually has almost the same thing (you can have a timeout on admin privs), but sadly Explorer is too retarded to use it properly :-( Perhaps this is something win7 can address.

    Is it really any cheaper? Their website quotes a price of $7.9m to get 420kg to LEO, or about $20,000 per kilo. This is just about exactly what we pay now. There's no cost advantage as far as I can see.

    The speedup is more due to new hardware than anything magic about Windows. In fact, a .net system is likely to need larger servers than the old C/COBOL thing they had before.

    3ms is still quite a bit slower than the NYSE, who (I think) claim 1ms for their linux-based system. But I imagine there are other factors here, like physical distance, the precise definition of 'transaction' and whether that's the guaranteed or typical speed.

    Are you sure it's not one thread per tab? That's what the person who did ie7 tabs seems to say:

    One design decision worth calling out is that our current implementation is fully multithreaded. Each tab is on a separate thread, and the frame is also on its own thread. This has some impact on the overall footprint of IE, but we believe this will allow IE7 to feel faster and provide an overall better user experience.

    No one's (I think) mentioned longevity yet. This is a really important benefit to something like LaTeX, especially for academics.

    I wrote my PhD thesis in LaTeX 20 years ago. I still have the source in my home area somewhere, and it still works perfectly. I needed a copy for my homepage and I was able to reformat it to make a double-sided, single-line-spaced, 10pt PDF in just a few minutes.

    With LaTeX, papers aren't fire-and-forget. You can be pretty confident that if you come back to a subject again, maybe many years later, what you wrote last time will still be useful.
