Comment Re:Contributions don`t have to be tit for tat ... (Score 1) 326

The problem with, say Ubuntu, packaging a lot of open source software without contributing upstream is that Ubuntu doesn't just package the software unmodified, they make changes to add desired features, fix bugs, and get different pieces of software to integrate better. But, since they don't contribute many of their changes upstream, the upstream developers will change the software without any regard for whether the downstream Ubuntu patches, so if the Ubuntu people want to pull in a new version of the upstream code, they also have to update their patches. As Ubuntu introduces more and more patches, they do more and more work maintaining their local branch of the software, until it gets to the point where they are expending as much effort as if they'd just wrote things themselves. For Ubuntu, this is most pronounced with GNOME, Canonical was not involved enough in GNOME development, so the GNOME guys went off and did their own thing while Canonical developed Unity. Now you have two frontends to GNOME, but the Ubuntu guys can't get certain upstream changes made, because upstream doesn't care about Unity, only GNOME shell, which means more work for Ubuntu developers. It's true that if you don't need to patch anything, then there's really no incentive to contribute, but when you *are* going to make modifications then you're in the situation Zemlin's talking about; it's almost always in your self-interest to get the changes merged in upstream. It's a little bit of extra work in the short-term that saves you effort in the long run.

Despite massive code-churn, chrome's UI has been pretty much static, at least for as long as it's had a Linux port. I think they're on to something. Once people get used to using the browser (or any program, for that matter), they don't want to relearn the interface after every update, they just want the damn thing to work.

Comment Re:Buy Apple Server Get Open Source Software (Score 1) 303

I imagine you could probably get someone to give you a pentium-based computer for free, and it may indeed perform sufficiently well to accomplish some basic, low-load server type tasks, but I think most people would prefer to put processors that were designed sometime in the last decade in their servers instead. The mac mini is a great little machine, and it's not even over-priced if you *want* something that small, but it's kind of limited in it's I/O capabilities. You can put two hardrives in the latest revision, as long as you're OK with losing the optical drive, and then you can spend the better part of a day trying to take one out and replace it if it fails. I suppose other people may have different opinions, but if I ran a server for my business, I'd want the hardware maintenance to be dead simple. In fact, I'd want hot-swappable drives, so I don't even have to take the machine down to do the drive replacement. And I'd want at least the *option* to install at least 4 sata/esate drives. The "mini-server" runs $999 currently, for that price, I'm sure you could build or buy yourself a much bigger, but also much more convenient to work on tower, with as powerful a processor, and significantly expanded I/O options, which also probably consumes a bit more power as well as performs slightly better. Then install CentOS and you're good to go.

Robot Throws First Pitch At Phillies Game 92

RedEaredSlider writes "The first ball at the Phillies-Brewers game will get thrown by a robot — but Roy Halladay's job is still safe. As part of an outreach program and the Phillies' 'Science Day At The Ballpark,' the University of Pennsylvania's School of Engineering and Applied Science is showcasing a robot made from a Segway and featuring an arm that acts more like a human throwing than an ordinary pitching machine. A pitching machine functions more like a gun, firing a baseball in what amounts to a straight line. But the robot has an armature connected to a hand that was specifically designed for throwing. Another thing the robot can do is identify the strike zone."

But, to reply more to the parent than to you: it's not like you're just going to be using this over wireless internet; some people actually have DSL or better connections with less then 40ms of latency; at rates like that a codec latency of 4ms is still 20% of the total latency. At that kind of latency 45ms you could play music with someone without driving yourself crazy because you both sound like your lagging behind the beat (you WILL both appear to be lagging to each other, but 45ms is a small enough amount of latency that it won't completely destroy the performance). In fact, even 100ms of total latency is probably survivable in a mid-tempo song (but will be very noticable), anything you can do at the codec level to chop that down improves the experience.

Comment Re:Dual Stacks..... forever... (Score 1) 321

Wasn't the whole point of IPv6 being essentially independent of IPv4 so that you COULD run dual stacks? Because it would be completely un-reasonable to be able to cut-over from one addressing protocol to another world wide in any reasonable fashion? So ... yes, dual stacks for the next 20 years on main-stream devices, maybe 70-80 years for niche needs sounds reasonable to me.
