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

Today's cameras are capable of capturing some pretty amazing shots, whether you're using a DSLR, a point-and-shoot camera, or even your cell phone. The average resolution of a contemporary camera can range anywhere from six to 20 megapixels--three to four times the quality of cameras of less than three years ago. However this clarity comes at a cost. As images get clearer, file sizes get bigger. JPEGmini helps you retake control over the enormous photo collection you have laying around by reducing the amount of space these files take up on your hard drive.

We've tried quite a few payroll programs over time, and they tend to share certain features, such as a database of company, employee, financial, and tax information that greatly simplifies the process of creating payrolls and reports.

PayWindow 2012 (build 10) is free to try for 30 days and costs $89.95 to register.

It's probably safe to say that business owners … Read more

A common complaint I get via e-mail or in comments on other articles involves a picture that breaks up into what look like little blocks.

Often, people incorrectly refer to these as "pixels," or blame their TV settings.

In fact, this artifact is in the source, and unfortunately, there's not much you can do about it.… Read more

Google has reached a licensing agreement with MPEG LA over patents that cover video compression, clearing the way for wider adoption of the Web giant's VP8 video codec and its streaming-video platform WebM.

The deal grants Google the right to sublicense the VP8 as well as the techniques in the forthcoming VP9 codec, which is already under development. MPEG LA also agreed to abandon its efforts to form a VP8 patent pool, which would have allowed it to cross-license its video patents.

Financial terms of the arrangement were not revealed.

Google has released a new data compression algorithm it hopes will make the Internet faster for everyone.

Dubbed Zopfli, the open-source algorithm will accelerate data transfer speeds and reduce Web page load times by compressing content up to 8 percent smaller than the zlib software library, Google said in a company blog post today. Named after a Swiss bread recipe, the new algorithm is an implementation of the Deflate algorithm, which is used in the ZIP archive format, as well as in gzip file compression.

"The higher data density is achieved by using more exhaustive compression techniques, which make … Read more

The process of compressing files is quite simple and more … Read more
