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 Payroll System is a fine example of the type. Once you've populated its database with the facts it needs, doing the payroll becomes a matter of a few clicks, not hours of calculations. 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

As long as e-mail remains the premiere business communication, file compression programs will be necessary. NXPowerLite Desktop Edition stands out in a crowded market by offering plenty of file-managing features and an overall great performance.

A great-sounding recording will sound its best only when it's properly mastered to LP, SACD, DVD-Audio, or a high-resolution file. Those formats will reveal the full glory of the music in ways that lower-resolution formats like MP3 or analog cassette always miss. But if you didn't have access to the high-resolution file to compare it with, a great recording will still sound pretty terrific as an AAC, M4A, or 320kbps MP3 file, because the recording's innate quality would shine through. On the other hand, a heavily compressed, processed and crude recording will always sound heavily compressed, processed … Read more

With all the news of Apple Maps' deficiencies and data leaks on iOS 6 devices, is the new iPhone 5 even worth it?

That's the question I try to answer in this edition of Ask Maggie. Apple has pulled the Google Maps app from its latest software, leaving the new iPhone 5 and other iOS devices to use its Apple Maps product, which many complain is inferior to Google Maps.

Also, Apple has issued an update to Verizon iPhone 5 smartphones that fixes a glitch in its Wi-Fi software. Instead of connecting to known Wi-Fi sites, consumers were really … Read more
