One of the biggest pet peeves in a technology enthusiast's life is the plethora of proprietary power cables that plague the consumer market, each with a slightly different design. Can't we all just get along and charge via USB? That utopian vision took one step closer to becoming reality yesterday, as the USB 3.0/2.0 Promoter Groups announced a USB power delivery spec that makes the every-port capable of delivering up to 100W of pure power. Yep, your PC can now charge a notebook. Heck, a laptop could even theoretically charge another notebook.
If you're looking solely at transfer rates, the USB 3.0 specification – with its 5Gbps speeds – may be plenty fast, but it already can't push the same amount of raw data as, say, Thunderbolt. New specifications coming down the pipeline, like SATA Express and external PCIe, are promising speeds that flat-out blow USB 3.0 out of the water. The USB Promoter Group's aiming to stay in the race with an innovative tactic; rather than compete solely with transfer rates, they're also turning the familiar USB connection into the equivalent of a 100W power cord.
Pegged to hit the market at about $250, the HD 5830 was viewed by some as a bargain alternative to the HD 5850. Perhaps a little less powerful, but still a big bang for your graphics card buck. Unfortunately, if the specs posted at IT168.com bear up, the HD 5830 isn’t going to just a little less powerful. According to these specs, hardware-wise the HD 5830 will have 320 fewer stream processors, 16 fewer texture units, and 16 fewer ROPs than its bigger sibling. That translates to a performance hit of 7.4 GTexels/s, 10.4 Gpixel/s, and 41.6 GSample/s. All this despite a core clock speed of 800MHz.
All-in-all, the HD 5830 looks a bit more like the HD 5770 than the HD 5850, except it sucks up a whole lot more power--more even than the HD 5850.
Lars-Göran Nilsson, of SemiAccurate, is disappointed by these specs, but isn’t really surprised: “AMD wouldn’t want the HD 5830 to be too close to the HD 5850 in terms of performance, as then the sales of HD 5850 cards would drop.”
The HD 5830 is expected to be launched in a couple of days. If the news is bad at least we don’t have long to wait for confirmation.
Relying on an anonymous tipster, Engadget is reporting that the Nexus One will come equipped with Android 2.1, Wi-Fi, Bluetooth 3.1 2.1 (and A2DP Stereo Bluetooth), a digital compass, an accelerometer, a 5-megapixel camera with a 2X zoom, 512MB of memory, and a 4GB Micro SD card. It will be able to handle JPEG, GIF, and BMP images; MP3, MIDI, XMF, iMelody, Ogg Vorbis, and WAVE audio; and MPEG-4, H.264 AVC video. No word on what talk and standby times are. The Nexus One will be for use only on GSM/EDGE systems (and will be quad-band). (Engadget posted a full set of specs, if you too can’t wait for Christmas morning.)
But, it probably matters little, because there’s not going to be one under your tree, now or any time soon. Engadget also reports that the initial round of sales of the Nexus One will be by “invitation” only. Whose to get the invites Engadget doesn’t know. But they do say that T-Mobile, at some point in the future, will be offering the Nexus One for sale.
Rules, rules, rules. It's one of the few things the open-source world has in common with its closed alternative. There are rules for downloading open-source projects. Rules for using open-source projects. Rules for distributing open-source projects. Rules for modify... ok. You get the idea.
It's one thing for open-source developers to define the legal parameters associated with the tinkering of their pet projects. That's the pill you swallow when you agree to download these bits of community-driven software. But that's also where the control factor ends. You can run open-source software on any platform you like. Depending on the parameters of the license, you can even populate your favorite open-source software applications to a new platform of your choosing--like a little bee in a digital garden, if you will.
Flying over the friendly skies of the closed-source world tells a different tale. Microsoft makes the rules here. Or, at least, as many rules as it can get away with making in relation to which of its operating systems you can use and how you can go about using them. Want to run a ton of programs at once? That's a license issue. Want access to additional functionality? Buy a better license. The list goes on, but it doesn't just end at the software level. A recent report has revealed Microsoft's intentions for Windows 7 in the netbook space, but this isn't the first time Microsoft has demanded that hardware manufacturers bow to a certain specification in order to bundle its operating systems along for the ride.
