This will make it a lot easier to plop your laptop on your desk at home and start working: wireless display adapters:

According to DisplayLink, there will be no performance penalty for using a wireless monitor, and displays will function at resolutions of up to 1680×1050 at 16.7 million colors. The actual wireless USB chip is produced by Alereon—that’s where the partnership comes in—but both companies seem confident that they can deliver a high-quality visual experience without noticeable tear or artifacts. DisplayLink’s products aren’t suitable for gaming or other functions that depend on split-second reaction times, but the company claims that DVD playback is flawless, even over its new wireless USB 2 technology.

By all accounts, DisplayLink’s current wired USB 2 technology works quite well at resolutions of up to 1600×1200, and a wireless solution could definitely increase the concept’s attractiveness, particularly in system deployments where space is at a premium. DisplayLink hasn’t stated how, exactly, monitors will interface with its wireless system. Ideally, the company could offer a small transmitter/receiver unit that plugs into a monitor’s DVI cable, with a similar device hooked into the back of the computer.

I think it’s safe to state flatly that if the technology can’t be used with any monitor, it’s a non-starter. But imagine if they build this thing the right way; you could have a hydra box with multiple monitors plugged in, and then connect the hydra wirelessly. The next step would be to use Bluetooth so its seamless.

Shamus has a familiar lament, the tangled nest of power cables, USB, and other assorted cables lurking beneath the average GeekDesk. He names it the Snarl, an apt name indeed. However, I recently managed to defeat the Snarl. I am now Snarl-free – behold:

I haven’t solved the miracle of wireless electricity. The secret to beating the Snarl is simple: cable management. Here’s a peek beneath the “hood”:

That’s the SIGNUM cable guide from Ikea that was designed to work with my JERKER model desk. Even if you don’t have that specific combo, you can achieve much the same thing with generic cable guides available from Radio Shack or Fry’s, or roll your own solution. I got the idea from Lifehacker, though I dispensed with the zip ties. It’s worked like a charm.

Of course there are people who take this sort of thing to another level entirely. But my ambition is far less; for my next act I’ll settle for adding a 4ft power strip to simplify things a bit more (inspiration from Gina). I’ve also got two more Snarls lurking behind the file cabinet on the left to tackle, but for now, out of sight, out of mind…

It’s worth noting that the Snarl is bad enough with a desktop environment, but it can only get worse with flex computing (ie, using a laptop as your main PC and externalizing everything). As the number of peripherals multiplies, the Snarl will become more powerful. However, in addition to physical cable management there are also technological solutions, like Bluetooth and Wireless USB that you can leverage.

A closeup and my gadget inventory below the fold: Continue reading “no snarl”

I’ve been sounding on a theme for a while about how I believe laptop computers are displacing desktops for the majority of personal (and business) applications. My view is that desktops will eventually be relegated solely to the workstation, server, and the high-end gamer markets, with some variation of laptops or “thin” desktops based on a laptop platform accounting for everything else. The key to this is using USB hubs and bluetooth to externalize the major computing components, including external graphics cards, storage, DVD. audio hubs, etc. When wireless USB goes mainstream this process will be even more accelerated. When going mobile however, you leave all that behind and run off the integrated graphics, sound, etc in a minimalist, lightweight configuration. Hence one box gives you the best of both worlds.

Along these lines there are some new technology developments worth mentioning. First, new external audio cards by ASUS, the Xonar U1, which

uses high-quality digital to analog convertors for crisp and clear music, games and movies. Gamers will like the fact that it supports EAX and DirectSound HW acceleration for gaming in Windows Vista and XP.

A headphone amplifier is built-in and other system specs include 96dB SNR and a frequency response of 20~20KHz at 32 ohms. ASUS claims the device can convert stereo audio to 5.1 virtual surround sound to give gamers positional audio cues. This sort of thing has been claimed before, but is rarely pulled off well.

An array microphone is bundled with the Xonar U1 and those wanting real surround sound will appreciate the SPDIF output with Dolby Digital Encoding.

Meanwhile, ATI has launched a new external TV card, the TV Wonder 650, which:

acts as a DVR tuner in order to record high-definition, digital, and analog content. Users can then use ATI’s Catalyst Media Center software to record television shows “for viewing on portable media devices such as the Apple iPhone, iPod, Microsoft Zune, Palm Treo, and Sony PSP,” an AMD spokesperson told Ars.

Features include support for Windows XP and Vista, as well as inputs for analog TV, FM radio, S-video, ATSC or ClearQAM F-type Coax for HDTV, stereo, and composite video.

So, now video editing and media center functionality can be added to the home station. Of course, that requires more storage, so it’s also worth mentioning that recent advances in hard drive technology – for which a Nobel Prize was recently awarded – mean we will be looking at 1TB hard drives for laptops in the very near future.

The intriguing thing is that the trend is already in full swing; notebooks are already outselling desktops and have been for some time. I think that the change ahead is in how people use their computers, not what type they buy. It’s still very hard to predict what the typical consumer’s computing model will look like in 5 years’ time, especially with WiMax on the horizon. The ability to reconfigure your computing space, coupled with immediate and universal broadband access, is going to lead to a flexibility that we’ve simply never had before.

This has intriguing potential ramifications for computer design downstream:

A new PCI Express standard has been approved that will allow for the development of and operation of external PCIe graphics cards. Dubbed the PCI Express External Cabling specification and approved by the PCI Special Interest Group (PCI-SIG), version 1.0 extends PCIe outside of the case.

The most obvious application for the new standard is external enclosures for graphics cards. Once you get past the price tag, the biggest barriers for many who would want to deploy a dual SLI or Crossfire system are heat, power, and space. Newer GeForce and Radeon graphics cards can emit a lot of heat while demanding a significant amount of power under high load. In addition, the need for large heat sinks and fans often means that you lose a second slot to a single PCIe graphics card.

Now imagine sticking a pair of graphics cards into an external enclosure with its own power supply and fan, hooking your monitor to that, and connecting it to your PC or even a laptop. Those are the kinds of possibilities opened up by the External Cable specification.

The advantages are well-summarized above, but take the idea further. We already have external bulk storage and external sound cards for laptops. Now imagine that via Bluetooth you also divorce the keyboard and mouse. External optical drives are also easier to deal with than internal bays. What’s left? Just a core that contains your essential apps and your critical data. You could conceivably just carry a small brick around, that is your computing core, and have it seamlessly adapt to your pre-defined computing environments. One might have an ultralight notebook chassis with a 14inch screen for travel; a beefed up desktop unit for the office and a silent SFF PC for the home. Your core is what contains your user profile and OS and authentication; biometrics keep it secure from anyone else’s use but yours. The bulk of your data remains accessible securely over the internet, by hooking up your master data store to a router with fixed IP and using strong encryption and VPN connections.

I’m sure this isn’t an original thought. Still, bears thinking about the advantages over the modern era. At the very least you’d only need to buy one copy of Windows 🙂
