We love to have tons of cool electronics hooked up to the big living room TV -- who doesn’t? But, if you’re like us, your significant other is less keen on seeing all that awesome black plastic and shiny metal, and you probably did the same thing we did: Went out and bought an overpriced, crappy piece of mass-produced furniture that has doors. Doors! And what do those doors do? They create hot pockets of electronics-killing heat that will shorten the life of our precious gear. All to keep the wife happy.
Fear not, heat haters. We put the Maximum PC brain trust to work in assembling a quick, quiet, and easy cooling solution for, well, just about any cabinet you’re willing to cut a hole in. We tested our solution with two of the hottest pieces of hardware we could find: an Xbox 360 and an AppleTV. With both boxed turned on, and with the door closed, the internal temperature of the cabinet quickly hit 130F. But after we mounted our heat-triggered fan, we saw the internal temperatures hovering a scant degree or two above room temperature. Want to find out how we did it? Hit the jump!
When it comes to Moore’s law these days, it seems like everyone’s a cynic. However, now there’s one more reason to be optimistic about the future of miniaturization, as researchers have published a paper describing a lithography technique which may provide a new means of producing chip features smaller than 32nm.
The technique involves the use of quasiparticles called plasmons to focus light at an incredibly high resolution. Chris Lee at Ars Technica describes the technology: “A lens, based on plasmons, can be created by a set of concentric metal rings. The fields from the plasmons in each ring act in such a way as to create a tightly focused spot of light. In principle, these lenses could focus light tightly enough to create features about five to ten nanometers in size.”
The problem with plasmon lenses is that they must be positioned at just 20 nm away from the wafer. The scientists claim to have overcome this hurdle with their new technique, which uses air pressure to control the lens’s distance from the wafer.
Significantly, the new technique eliminates the need to create a new photomask for each revision to the chip, potentially lowering costs and speeding up development.
The R600 features an Intel Core 2 Duo Ultra Low Voltage processor and up to 5GB memory. Certain models feature a 128GB SSD. The lightest laptop in the world has a 12.1-inch screen and an impressive 9-hour battery life.
Tosh also unveiled the Tecra R10 notebook to woo business users. The R10 Tecra chassis cocoons a 2.4 GHz Intel Core 2 Duo processor, 4GB DDR2 memory, an Nvidia Quadro NVS graphics controller with 128MB video memory and a 200 GB hard drive. The R10 is priced $1999.
The technique leverages the parallel processing power of Nvidia’s latest graphics cards to speed up the “password recovery” process by 10,000 per cent. Global Security Systems (GSS) has advised enterprises to deploy VPNs for safeguarding their WiFi networks.
We, too, can only advise you to secure your office WiFi network using VPN encryption before professional industrial sleuths start waging brute forcing blitzkriegs using ordinary graphics cards.
In what may be the biggest thing to happen to cryptography in a very long time, the world’s first computer network built with working quantum encryption technology has been demonstrated in Vienna. The network connects six locations with a total 200 km of fiber optic cable and the encryption system is said to be completely unbreakable, according to the BBC.
The network transmits a stream of millions of individual photons a second through the cable, and can detect if anyone has attempted to listen in on the stream.
Gilles Brassard, of Montreal University explained to the BBC how the system can be unbreakable: “All quantum security schemes are based on the Heisenberg Uncertainty Principle, on the fact that you cannot measure quantum information without disturbing it. Because of that, one can have a communications channel between two users on which it’s impossible to eavesdrop without creating a disturbance. An eavesdropper would create a mark on it.”
If an intrusion is detected, the data transfer is immediately rerouted through different nodes.
Pretty cool, huh? Let us know what you think of this new technology after the break.
Last week we updated our Budget Badass to reflect the current price drops and made some improvements in hardware. This week we are shifting our focus to the power user. Shifting our focus also means shifting our cost up, but a higher budget means better hardware and faster performance. We've made a couple of adjustments to the video card and CPU as well as adding a second hard drive while taking your suggestions into consideration. While the final cost of this build exceeds a little past the $2500 mark, we believe the extra performance gain is well worth it. Keep in mind this is a Power User's PC, where our main focus is on utilizing the power of the processor through multitasking and multimedia programs. Read on to see our new setup for this Power User beast.
The largest and second largest PC manufacturers in the world, HP and Dell respectively, haven’t taken an instant liking to WiMax it seems. The launch of the first commercial WiMax network in Baltimore, earlier this month, inspired OEMs Acer, Aspire, Lenovo and Toshiba to launch WiMax-enabled notebooks. However, Dell and HP did not rush to take advantage of the launch.
Moving to the largest PC supplier HP, even though the company is testing WiMax it has no immediate plans of offering support for the technology in its notebooks. It has asked its customers to explore the option of purchasing WiMax enabled PC card, USB dongle or ExpressCard, if they are keen on using WiMax. Dell and HP want to wait until WiMax becomes available in other major cities.
Many of the modern soldiers are currently saddled with battery packs that can weigh upto 20 pounds. The batteries, of course, are used to power the wide gamut of equipment that a modern soldier carries with him. However, the soldiers can now heave a sigh of relief as a wearable power system is soon going to replace the heavy batteries.
The team of America’s DuPont and Germany’s SFC Smart Fuel CellSFC Smart Fuel Cell has won the $1 million Wearable Power Prize organized by the Pentagon with its M-25 fuel cell. The M-25 weighs only 3.71 kilograms and can provide 20 watts of average power for 96 hours. The wearable system includes a fuel cell and a battery. The army has already begun using the system, though in a limited way.
Wi-Fi is fast emerging as the most popular technology for wireless communication between disparate gadgets, but security remains a major concern. However, researchers at Boston University’s College of Engineering are working on an alternative way of connecting devices that will be innately more secure than Wi-Fi.
Moreover, an LED-based communication technology will enjoy a distinct security advantage. It will be more secure compared to Wi-Fi due to the inability of light to penetrate through opaque surfaces like walls.
“Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires,” said an ebullient Thomas Little, a BU engineering professor, about the idea. Soon, our networks will quite literally “light up”.
Just as we nerds have overhyped some technologies, we've also overlooked some even better alternatives. PC World has put on its thinking cap and posted its picks for the ten most overrated technology products and services - and alternatives that deserve a closer look.
So, How Would You Rate These Contenders?
Ultra-portable laptops versus mini-laptops
Microsoft Zune versus Apple iPod Touch
Windows XP versus Windows Vista
