  3. Accomodate? Adjust? on Cat-like Robot Runs Like the Wind · · Score: 1

    Based on the very limited view we are given of this thing, I start to seriously wonder why a real-time Linux system was used. It looks like it is just actuating legs blindly. Real-time systems are tremendously useful for responding to physics in... (wait for it)... real time. "I'm starting to fall! Let me adjust this this way to prevent it. Can't wait 30ms for a response! Need to respond now, otherwise the response will be wrong." Sure, it's actuating its legs in a manner that is fault-tolerant (It can travel down breaks in the terrain up to 20% the length of its legs), but that is entirely based on the springs absorbing the extra unexpected impact and then losing it after the leg leaves the ground again, not a real-time adjustment.

    This depresses me a little because, like others, it feels misleading. Mention real-time linux! Does it help or hinder? No, not really. Mention that it's cat like! How is it cat-like? Um... It has four legs and springy bits! Oh, and it goes faster stably than any other quadrupedal robot in its size bracket. How fast? That's not very fast really... But focus on the fast-ER part!

  7. Re:Best way to filter web content: on Ask Slashdot: Best Way To Block Web Content? · · Score: 2

    Well, besides the fact that you would need to block TCP as well as UDP (RFC calls for support on both and longer messages, such as zone transfers, require TCP due to UDP's content length limits), you also have the benefit of the fact that this would block exploits that make use of port 53 for communication on the strong likelihood that it is completely unfiltered.

    The AS article asks where is the best place to filter though. This gets tricky. The request doesn't indicate whether this is enterprise equipment or consumer. The mention of router-based filtering implies consumer though, so I'll focus on that.

    First off, a good number of consumer routers do not have the processing power to handle full filtering at high speed. Even enterprise appliances such as iPrism require heftier units when the pipeline speed exceeds a certain threshold. As a good example, a Linksys 625 Wireless Router can handle filtering with no rulesets up to about 50-60Mb/s. Rules are relatively efficient, but there is no way in many cases to automate rule implementation, and when the ruleset increases in size the capability of the router to handle it drops to around 20-30 Mb/s. Fine if the WAN uplink is perhaps a 15Mb/s line, but catastrophic if you're trying to get full use from a 105Mb/s cable or fiber line.

    The end answer really comes down to a balance. Implement filtering at the furthest end that you carry absolute sovereignty over, balanced by duplication of effort and complexity of implementation. Replicating rules over thousands of endpoints is complex enough and lacks enough control that performing the filtering at the trunk is more efficient and effective. By comparison, the ability to control one or a few computers in a home is substantially more likely and will take the burden off the limited processing power of a consumer router. Walking a rule manually to five endpoints is trivial compared to dozens, hundreds, or thousands.

    If the uplink is small enough to allow filtering at the router and the eventual change and replacement of equipment will allow easy transfer of rulesets and administration, work from the router or a similar trunk location to globalize and centralize effort. If the endpoints are spread enough or there is sufficient lack of control over them to warrant such, again, work from the trunk. If enough trust exists in the endpoints to offload the work onto their substantially-stronger processors, and administration of rules to and of the endpoints is trivial, filter at the endpoints.

  8. Re:Can't Go Backwards on Ask Slashdot: Why Is It So Hard To Make An Accurate Progress Bar? · · Score: 2

    I know that NSIS Installers at the very least base the default progress bar internally* on the line number through the length of the entire set of installation process code. This makes it quite fun when you have long position jumps in the code or repeating loops that have enough code to cover a good chunk of progress. I would expect that several other installers may use the same base internal calculation of the progress bar.

    *The progress bar can also be controlled manually within the code for the coder to be nice or exceptionally evil as they see fit.

  9. Re:Who knows, I'm not a lawyer... on Piriform Asks BleachBit To Remove Winapp2.ini Importer · · Score: 5, Interesting

    Maybe I'm missing something here, but....

    Group 1 makes a third-party add-on that works with Company A's and Company B's product. Neither company controls Group 1.
    Company A is not using anything at all from Company B, but makes use of Group 1's items.
    Company B is telling Company A to remove the feature of using Group 1's items because it violates ToS.

    So either Company B's person somehow thinks that the Company A product violates B's ToS (which is not in effect, since B is not in use at all and the interaction is with a third party), or B thinks that A's implementation violates Group 1's ToS and is giving a "courtesy" alert. If the former, then a simple response pointing out that A's product and feature does not utilize anything under the control of Company B and thus Company A is not subject to B's Terms of Service since B is not providing any services to A would suffice. If the latter, then check the ToS of Group 1 and remedy if the allegations are correct.

    I suspect that somebody (Louise) saw the words "CCleaner's Winapp2.ini files" in the ghacks article that implies (apparently incorrectly) that the files are created by and owned by Piriform, so assumed that her company owns them and nobody else is allowed to use them. Instead the case looks to be that "Group 1" creates and owns them and her company USES them, so her company's ToS does not apply to the use of a third party item they don't own or control.

    Way behind the times. Webroot took over the light factor by a huge margin (sub-MB total installer size anybody?).

If it's good, it just tosses out the journal. Upside: Light. Really. Downside: You can be "infected" for an average of ten minutes before it catches, neuters, and then guts the infection. Upside to the downside: The unknown is not given access to sensitive things (screenshots, keylogging, etc) while it's unknown.

  20. Re:Why X360 and Kinect exclusive? on Skyrim Is Getting Kinect Support, Dragon Shouts Included · · Score: 2, Interesting

    I'll hit both sides in this case.

    The first consideration is that PC Gamers, who already spend a ton of money on the gaming rigs and have a lot more capability than any console's half-decade-old tech, feel now like the game manufacturer is treating them like second-class citizens. PC games that have Console-optimized content, focus on the console development over PC development, generally a perceived lack of respect for the PC gaming population. Literally to the point where, in this case, development of mods for the PC is not only effectively almost Open Source, but Bethesda isn't even making any official mods except HD packs that don't look as good as the third party ones.

    It's to the point where the people who spend the most money on their hardware have the least support. Then the fact that the game is throttled to work best on what is effectively nearly ancient technology these days, their super-hardware does them little good. Try using a 1x3 surround-screen setup and you'll quickly discover that the menus and UI are sized based on the width of the screen without accounting for the height. Unusable. Skyrim could have been a beautiful experience for the high-powered gamer, but it isn't unless the gamers themselves fix it. Fixing it is often a battle against the official developers also, as official patches that fix a handful of things also break dozens of third-party fixes.

    Now that it's to the point where PC gamers are feeling like they're being told "Sorry, your gaming experience can be far too much better than those peoples'. We need to give you a handicap.", we're getting less and less pleased. Here's a comparison: What would you do if Amazon.com said "We're giving out cool stuff to people who buy things from us! But... We decided not to give it to anybody who lists a book on our system. Sorry, Michael, you've got all the benefits of publishing a book, so you can't have this stuff." I would expect you to potentially feel slighted. All in all, it's human nature to not want to be considered an afterthought, unsupported, inferior market segment, etc. People buy high end PCs to have a better gaming experience than the people who spend a quarter as much on a console. They don't expect to be tossed the scraps and told to fend for themselves by the game developers just because they have better hardware.

    On the other side of the coin, there are many times more users buying it for the consoles. It's just a "business decision" to make the important stuff for the bigger market. One can also consider that the "additional content" probably has a strong propensity for carrying a cost, so the highest revenue will come from the larger market segment. Money speaks, after all.
