If there’s one thing that should be learned by everyone with the most recent hacking fiasco of Wired’s Mat Honan, passwords aren’t secure. A team of researchers from Stanford and Northwestern universities, as well as SRI International, have been experimenting with security to use the brain’s innate ability to learn and recognize patterns.

All-optical routers managing Internet traffic would be much more energy efficient than what we have today, but their development has been hindered by the lack of optical memory devices. Researchers have developed this kind of device, which could pave the way to a faster and more energy-efficient Internet.

Strange & Funny USB Hubs: Add a Bit of Fun to Desktops

111611_rg_StrangeUSBHubs_01.jpgWe always like having unobtrusive tech, but there comes a time when a bit of fun isn’t out of place. USB flash drives are usually the domain of the silly, but USB hubs come in a close second when it comes to the strange and whimsical…

Make Your Old PC Into a Data Server

110711_rg_DataCenter_01.jpgLike many people, we’ve got a MacBook, but this is a recent update. We’ve always had PC computers. At one point, there were probably around 6-8 old PCs in various states of assembly in our home office, which got a bit cluttered. That being said, there are many things that you can do with old PCs, and making yours into a data server makes sense since it’s something that desktops do well.

Karuma PlayBase: Tablet for Toddlers?

While I’ve seen plenty of toddlers playing with iPhones and iPads, since they aren’t completely smash-proof, you might want to think about giving your little terror a PlayBase from Karuma instead. This is supposed to be an affordable tablet that’s made for younger children. It’s perfect when you don’t want to hand over your iPad 2 and risk having its glass screen shattered or aluminum back dented.

Green Laptops: Going Eco-Friendly on the Road

081211_rg_GreenLaptops_05.jpgAs with green PCs, there isn’t much information available about the how environmentally friendly your current laptop is, but with a bit of digging, you can find out a lot about your next one. While going green is great, you also have to think about how long you’ll be able to use your next laptop. If you can keep it an extra year, you’ll not only save money but also keep the environment cleaner by consuming less.

Cheap Ways to Rejuvenate Your Aged and Ailing Computer

081011_rg_RejuvenatePC_01.jpgWe’ve been living with an older PC for a few years, but like many users, we don’t really want to spend too much money on upgrading it fully, since we’ve added a couple new laptops to step in for the PC’s deficiencies. But using a PC for 5-7 years is possible, you only need to know which parts to upgrade when performance begins to hamper productivity…

Education iMac Drops Below $1,000: Will You Get One?

I’ve mentioned before that I’m somewhat ambivalent about the all-in-one PCs, mostly because they use laptop parts to get to that svelte size, but Apple has announced the specs of their education iMac, which sits at $999. That’s $200 less than the cheapest consumer model. You won’t get Thunderbolt or a Core i5, but you’ll get a decent computer for that price.

The Thick and Thin of MacBook Air Alternatives

080311-Sony-VaioZ.jpgA walk down the store aisle and it’s obvious not all laptops are created equal: some are thinner, a few offer desktop power in a portable form factor, others just look cooler. Right now the hype meter is reading high with the newly released MacBook Airs, but that doesn’t mean there aren’t other laptops to consider that share a slim form factor and powerful specs…
