Raspberry Pi 2 with Quad CPU

The next-gen Raspberry Pi 2 runs on a 900MHz quad-core ARM Cortex-A7 CPU with 1GB LPDDR2 SDRAM. It offers six times faster and two times the memory of its predecessor. Raspberry Pi 2 also looks identical to Raspberry Pi 1. The connectors on the Raspberry Pi 2 are in the same place and have the same functionality, so existing users will find it easy to make the transition. Also, the board can still be run from a 5V micro-USB power adapter. All for $35, a bargain.

Snappy Ubuntu

Snappy Ubuntu Core has a minimal server image with the same libraries as regular Ubuntu, but it offers a simpler mechanism for obtaining applications. It’s faster, more reliable and more secure, according to Canonical. Snappy Ubuntu Core will ensure Snappy Apps “cannot harm the operating system and other Snappy Apps,” said Canonical’s Maarten Ectors. Rest the rest of the article.

Leap Second

What’s all the fuzz about a leap second? Astronomers will add one second at the end of June 30, 2015. When the clock reaches 23:59:59, it will then go to 23:59:60 and then turn to 00:00:00. By the way, the leap second will not break the Internet as some have said it would. LA Times has a nice article of the upcoming leap year.

Linus Torvalds, creator of Linux doesn’t seem to be worried about it. He said patches were already added the last time it happened in 2012. Torvalds continues by saying the creators of Posix made a mistake years ago when they designated a day to have 86,400 seconds. Then, there’s that 2038 problem.
