The Gtech AirRam: not enough vacuum for the price

Don't let the Gtech AirRam's sleek looks and data gathering feature fool you, this rechargeable stick vacuum isn't worth $349. Its price isn't so shocking when you consider the fact that the Dyson DC59 Animal retails for $499. The DC59, however, is a champion performer and with its detachable handheld unit and assortment of attachments offers lots of flexiblity.

The AirRam, on the other hand, offers no attachments, and had a mediocre showing in our lab, coming in last among other stick vacs on our pet hair and fine debris tests. Its Data Bridge feature, which … Read more

Samsung chip advance paves way for phones with 4GB memory

In a move that should help fix a key performance bottleneck in mobile devices, Samsung announced Monday it's developed a new 8Gb DRAM memory chip for high-end phones and tablets.

The chip uses a low-power DDR4 (Double Data Rate 4) interface that can transmit 3.2Gbps over each of its electrical connections, twice that of today's DDR3 memory, Samsung said. And it consumes 40 percent less power.

When the new memory chips ship in 2014, they'll pave the way for premium devices with 4GB of memory. Today, Samsung sells 4Gb and 6Gb DDR3 memory chips used in … Read more

Tab overload slowing you down? Speed up your browsing with TGS for Chrome

Tab browsing is an amazing tool for multitaskers and ADHD-prone Web surfers everywhere. But one of the most annoying things about using Google Chrome's tab feature is the massive amount of resources it sucks up. Even though we love the idea of multiple tabs, chances are we aren't looking at every one of them at the same time. And because Chrome opens every new tab as a separate process, your system is left with very little memory for anything else. The Great Suspender, a Chrome extension, aims to solve this problem by putting on hold the tabs you … Read more

Hike! Watch NFL players pass with Google Glass

Imagine a football game decades from now. After defining all the regulations, players could utilize Google Glass-esque headsets integrated into helmets and have a high-tech array of features at their disposal. Coaches could send messages to players and alter plays on the fly or watch first-person footage of a play going down. A world where plays don't get screwed up because of excessive crowd noise.

In a recent segment aired on ESPN, reporter Katie Linendoll shared the Google Glass experience with several NFL players from the St. Louis Rams. The video shows Rams quarterback Sam Bradford's point of view as he throws a pass to running back Tavon Austin -- and then another clip from Austin's view. It's an interesting example of how Glass could provide a new learning tool for coaches and athletes in professional sports. … Read more

The necessity of regular use of the 'purge' command in OS X

When using your Mac, active programs, documents, and system resources will be loaded into memory (RAM), where they can be accessed quickly to run and perform computations. While active memory contents are maintained in memory, the system also keeps some recently used but inactive processes and data there in order to quickly revive them, if needed.

These memory allotments should be managed dynamically for optimum performance, but some people who regularly run low on RAM may be concerned about this and resort to using "RAM cleaning" programs. One of these is the "purge" Terminal command that … Read more

Memory compression brings RAM Doubler to OS X Mavericks

Today at the World Wide Developer Conference keynote, Apple announced a new feature in the upcoming OS X Mavericks that is reminiscent of the RAM Doubler technology available for classic Mac systems in the '90s.

In the mid-'90s, Mac systems came with 8MB to 32MB RAM, and as has always been the case, greater application usage required more RAM.

Overcoming RAM restrictions required you either purchase more RAM, or enable and expand virtual memory usage in the system's control panel to make use of the hard drive as a location for RAM contents. Unfortunately these features were either … Read more

Review: Smart RAM Booster speeds up your Android device

Smart RAM Booster increases the speed of Android devices through several functions. It can stop the functions of applications running in the background with a multifunction widget or through the applications' user interface. There is also a cache cleaner that seems to speed the device up.

The user interface is pretty basic but the advanced settings can be confusing. For users not familiar with this type of application, some of the options may need more thorough … Read more

Process Lasso Review

At Download.com, we've long recommended the excellent Mark Russinovich-created and Microsoft-supplied Process Explorer freeware, which provides scads of info on all of your Windows PC processes and options for managing them. Well, Process Lasso is like the peanut butter for Process Explorer's chocolate. It lets users set default priorities and CPU affinities for specific processes, establish rules for how processes behave, and also create alerts and automatic events for when processes misbehave or use too much memory. The interface is outdated and not beginner friendly, but Process Lasso offers very useful features in a powerful little package.… Read more

SuperRam Review

Computers once had such small memories that Windows couldn't remember where it put its keys without registering them (it still can't, actually), but today's PCs have so much random access memory (RAM) that Windows can do much more than walk and chew gum at the same time, computationally speaking. Plenty of PCs still come up short in the RAM department, though, including a lot of older machines struggling to keep up with today's bloated Web sites and high-quality multimedia. For those PCs, the answer is the same today as it was way back then: a tool … Read more
