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.

What is Snappy Ubuntu?

Canonical released Snappy Ubuntu a month ago. From Ubuntu Insights:

Today we’re announcing “snappy” Ubuntu Core, a new rendition of Ubuntu for the cloud with transactional updates. Ubuntu Core is a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users – that’s why we call them “snappy” applications.

Snappy apps and Ubuntu Core itself can be upgraded atomically and rolled back if needed – a bulletproof approach to systems management that is perfect for container deployments. It’s called “transactional” or “image-based” systems management, and we’re delighted to make it available on every Ubuntu certified cloud.

Shortly after, Canonical mentioned Snappy Ubuntu is now available on Amazon Web Services (AWS).

Canonical is delighted to announce the availability of snappy Ubuntu Core on Amazon Web Services (AWS).  Snappy Ubuntu Core is a new ultra fast Ubuntu that is designed for extremely fast deployment on Amazon EC2.

Ubuntu Core is the new “snappy” rendition of the popular cloud OS, with a very lean and secure base image that features transactional updates for both system and applications. Snappy Ubuntu is perfect for container-oriented deployments using technologies like Docker.

Customers can try a beta version of snappy Ubuntu Core today on Amazon EC2 by launching an instance of Ubuntu Core. Here are the instructions.

I can’t wait to try this with Docker.
