A few years ago we started to see optical discs that could store as much as a terabyte of data, making a 50GB Blu-ray disc look like small potatoes. But new breakthroughs mean we could see DVD-sized discs that could hold up to 1000 times as much data.
Whether anyone will buy those discs is another question, but they could come in handy for large-scale data storage projects, or delivery of Ultra HD videos in areas where broadband internet isn’t widely available.
Here’s a roundup of tech news from around the web.
- One day optical discs could hold up to 1 petabyte of data
If you thought Blu-ray disks could store a lot of data, you ain’t seen nothing yet. There’s a new technique for storing data on optical disks that could allow for up to a petabyte of data on a single disk. Of course, a few years ago we saw terabyte optical disks too, but those haven’t exactly become commonplace. Physical media just isn’t as popular a way to distribute data as it once was. [Slashdot]
- Rockchip RK3066 added to the mainline Linux kernel
A handful of folks have been working to get Linux-based operating systems such as Ubuntu to run on devices with Rockchip RK3066 processors for a while. Now support for the dual-core ARM Cortex-A9 chip has been added to the mainline Linux kernel. For most folks that doesn’t actually mean much yet, but it could lead to further development for the chipset. [CNX Software]
- Tobii, Synaptics develop ultrabook prototype with eye tracking tech
Tobii’s eye-tracking software lets you control a PC just by looking at it. The company was showing off some pretty nifty Windows 8 demos at CES in January, but at the time I was told it could be a while before the system was ready for portable notebooks. Now it looks like the wait could be over soon. [TechCrunch]
- Aol Reader launches in private beta (Google Reader alternative)
Google Reader shuts down for good in less than two weeks. Plenty of companies are hoping to win over fans of the cloud-based news reader, including some blast-from-the-past companies such as Digg and now Aol. [AllThingsD]
- In-depth look at Digg’s efforts to build a Google Reader replacement
Speaking of Digg’s reader, it’s set to launch to the public on June 26th. A number of news sites have featured articles about the transformation of Digg recently, and the race to build a Google Reader replacement. This is one of the best you’re likely to read. [Wired]
