News and other tidbits that Chad Cloman finds interesting enough to share
Apparently, vibrations can have a significant effect on hard drive performance, even if you just shout at the drive. In one study, the researcher found that “Performance improvements for random reads ranged from 56% to 246% while improvements for random writes ranged from 34% to 88% for a defined set of industry benchmarks.”

Adobe has released Flash Player 10.1, which includes critical security updates. Adobe products are well known for their susceptibility to malicious hackers, in part because of their ubiquity. Note that you’ll need to install two copies of Flash Player, one for Internet Explorer and one for all other browsers. No, seriously.

Sony has announced its intentions to stop producing 3½” floppy disks, effectively putting an end to the medium. I remember how large the 1.44MB capacity was, when they first came out, and how much more rugged they were than the 5¼” disks (that were actually “floppy” disks).

Here at Chad’s News, we’ve previously covered one of the problems with intermittent energy sources like solar and wind: how to store the power so that it can be used on-demand. Until that happens, the need for traditional fossil fuel plants will remain.
The linked article describes a large battery nicknamed BOB, that will provide reliable power to the town of Presidio, Texas. The battery is expensive ($25 million), and the town is small (pop. 4167), so I’m not sure how well this would work on a larger scale. But it’s a step in the right direction.

Seagate is coming out with a 3TB hard drive later this year, but don’t rush out to buy one, because it won’t work on your existing computer. The current hard drive addressing standard was developed back in 1980 and only allows for a maximum of 2.1TB. Back then, that was considered to be an absurdly high number that would never be reached.

Audio, video, and image files are so large that they effectively can’t be used on the internet, or in portable devices like cameras or iPods, without somehow making them smaller. And while there are ways to compress files without losing any of the data (think ZIP files), most of the formats we use today, MP3, JPEG, GIF, MP4, AVI, etc., use lossy compression. A song saved in the MP3 format, for example, throws away some of the audio but does it in such a way that most people don’t notice the difference.
But repeatedly compressing the same file will cause it to lose more and more of the actual data—sort of like making a photocopy of a photocopy. This is why I don’t use Audacity to edit MP3 files, because it first converts them to the WAV format for editing then back to MP3 for saving.
The linked article shows what happens to a video that was re-saved a thousand times. The author created the original video, uploaded it to YouTube, downloaded it, uploaded it again, and so on until he had a thousand uploads. The final video very clearly shows the cumulative effect of lossy compression.
