Part of virtual memory on a computer is where the contents of RAM are written to the hard drive (as a special file called a "swapfile") to free it up for other uses. As you use your computer, the system will load programs and data into RAM, which is like having your work on the top surface of a desk. As you place more items on the top of your desk (RAM) it may get cluttered, so to keep your work flow efficient you might free some space by putting a few items into the desk's drawers (… Read more
The wide-release version of Firefox 7 brings changes to the majority of Firefox users that the beta and Aurora channels have been playing with for some time. These include claims of significant gains in reducing memory use, "often 20 percent to 30 percent less, and sometimes as much as 50 percent less," a company representative wrote in a blog post based on work by Firefox developer Nicholas Nethercote. … Read more
Despite a globe-spanning, bruising legal battle with Samsung, Apple has little choice but to keep getting key parts for its iPhone from the electronics maker, according to sources and a news report.
Those key parts include the iPhone 5's expected main processor, the A5, as well as system memory and flash memory--components that together make up the electronic core.
Sources who track the chip industry say that Apple must stick with Samsung for the time being. Some rumors had claimed that Apple would switch to Taiwan Semiconductor Manufacturing Company (TSMC) for a so-called "shrink" (smaller version) of the A5 for the iPhone 5.
That's simply not doable, sources tell CNET. TSMC has not perfected the advanced manufacturing processes needed to make an A5 for the iPhone and, maybe more importantly, it's prohibitively difficult to jump to a different manufacturer for the same chip design. … Read more

Apparently a shortfall in PC sales and demand has resulted in a surplus of RAM from various manufacturers like Samsung, Micron, and Nanya, and as a result the cost of RAM upgrades has been steadily falling as these surpluses have been pushed into the market. Only a few months ago an 8GB RAM upgrade for a laptop system would have cost around $100 to $150, but these days they are going for between $50 and $70. Similarly, RAM prices for desktop systems are also dropping.
What this means is if you are in the market for a RAM upgrade then … Read more
This post is more of a heads-up than how-to. If the approaching 10th anniversary of the 9/11 attacks has put you in a reflective mood, there is a wonderful iPad app that provides a retrospective of the World Trade Center, a look at the projects occurring at the site today, and a look to what the future holds for the National 9/11 Memorial and Museum. The app, The 911 Memorial: Past, Present and Future, is free, though only for a limited time.
The app was created by Steven Rosenbaum, the filmmaker behind 7 Days in September, a documentary … Read more

Chemists at Yale University are unveiling what they call the first practical method to create the compound huperzine A, which is a naturally occurring extract of Chinese club moss.
The enzyme inhibitor has been used widely in China and now beyond to treat memory loss in disorders such as Alzheimer's disease, and some research indicates it might help fight the effects of chemical warfare agents in primates.
But the plant, whose scientific name is Huperzia serrata, is both slow-growing and overharvested, resulting in a price tag upwards of $1,000 per milligram. The Yale team's success creating a … Read more
