  1. Re:It's so obvious... on IEEE Says Multicore is Bad News For Supercomputers · · Score: 1

    Perhaps this will lead to CPUs with large L1 caches specifically for supercomputing tasks, who knows...

    Even discounting price concerns, L1 caches can only increase a certain amount. As the capacity increases, so does the search time for the data, until you find yourself with access times equivalent to the next level down the cache heirarchy, thus negating use of L1. L1 needs to be /quite/ fast for it to be worthwhile.

  2. Re:Well doh on IEEE Says Multicore is Bad News For Supercomputers · · Score: 1

    With any pool of memory, there is some limit to latency and throughput. Thus, the more processing elements you throw at the problem the more they compete for this resource.

    Now, if you can separate this memory into discrete pools associated with each processing element, you have less contention (locally) hence the possibility of lower latency and higher throughput (locally).

    If you can design your algorithms such that multiple writers (and hopefully readers) to the same location happen infrequently, then you have a net win, despite higher costs addressing foreign memory.

    You want filtering? No problem, we make a law that your ISP has to provide it at your request, for free

    Australia already has that law. Free NetNanny for everyone that wants a "clean" connection.

    Now ask me how many people have taken up this offer...

    Only until the end of the year, at which point the government is mysteriously discontinuing the software...

    The issue here is to stop people access child porn.

    From what I'm aware the idea is supposed to be about providing internet which is rated as suitable for persons of any age.

    That it's degenerated into a 'we have one filter, lets just regulate the rest too' scenario is incredibly worrying and indicative of another agenda.

    The fact that the government is hell bent on providing global, mandatory, ISP level filtering is ludicrous considering the claimed goal.

  8. Re:Dear Federal Government: Bring It On... on Australian Government Censorship 'Worse Than Iran' · · Score: 1
    The filtering mechanisms have tremendous performance impact. I'm not sure if it's protocol independant, but I'm willing to bet that whatever your choice of bypass, the general internet performance is going to be massive regardless.

    While you'll still be able to bypass, that's not something I'm willing to put up with simply because the government have a half arsed plan to block certain material.

  11. Re:Incognito mode actually isn't really so... on Google Chrome, Day 2 · · Score: 1

    There's no evidence that Chrome sends anything but the *hash* of the site you type in the address bar, and does not send your browsing history anywhere at all - whether in incognito mode or not.

    So you're telling me that Google, of all people, do not have the resources to compute the hash of each URL as they crawl the web? And create an efficient lookup against those hashes... Interesting...

    That said, from what I've been told the mechanism is that a list of hashes of bad URLs are downloaded every 30 min which are then checked from within your own computer.

    We have periods of regular brownouts in our house. Our previous router (Linksys of some description) would recover from these, regaining line sync and all services. Our current router (Billion, piece of crap) will quite often require a manual power cycle to regain anything beyond wired internal LAN switching. Hence, power outages for us require a power cycle.

    Yeah, it appears so. In order for the random error to be useful for non-military use the error had to be somewhat uniform across large regions. So, once you established the error on one known point you were pretty right.

    If I understand it correctly, there is a predictable pattern of error introduced into the publicly available signal. If you know the key of the day you should be able to remove the introduced error. Also, I believe there is an ability to introduce more substantial error at will. Take it with a grain of salt, vague recollections of wikipedia a few nights back.

    It's a known problem for some people, experienced it myself. Try closing all other applications that could possibly have the audio device open. Failing that, try logging out then back in again and running it first up (essentially just ensures you dont have audio device tied up). I run into this problem with a few other applications, so it's not unique to the game.
