Until recently, doing time series analysis at scale was expensive and almost exclusively the domain of large enterprises. What made time series a hard and expensive problem to tackle? Until the advent of the NoSQL database, scaling up to meet increasing velocity and volumes of data generally meant scaling hardware vertically by adding CPUs, memory, or additional hard drives. When combined with database licensing models that charged per processor core, the cost of scaling was simply out of reach for most. read more

The notion of using robust, random passwords has become all but mainstream-by now anyone with an inkling of security sense knows that "password1" and "1234567" aren't doing them any favors. But even as password security improves, there's something even more problematic that underlies them: security questions.

Security is an ongoing issue for all operating systems, including Linux. While Linux has generally had a good reputation compared to Windows when it comes to security, no operating system is perfect. A writer at Ars Technica recently examined the issue of security and the Linux kernel.

The Linux kernel today faces an unprecedented safety crisis. Much like when Ralph Nader famously told the American public that their cars were "unsafe at any speed" back in 1965, numerous security developers told the 2016 Linux Security Summit in Toronto that the operating system needs a total rethink to keep it fit for purpose.

Open source software is in danger of being beaten at its own game by upstart services that are tightly integrated, less complex, and easier to use. That message was at the heart of the cautionary tale told by Stephen O’Grady in his keynote at this year’s ApacheCon North America in May.

Stu Keroff will be speaking at All Things Open in Raleigh this year.  The Community School of Excellence (CSE) Asian Penguins are the world's first and only Linux user group based in a Hmong charter school.

Last month we discussed setting goals for your community metrics program. These goals serve as a constant reminder of what you want to achieve in the program and should be used as metrics themselves when deciding exactly what you are going to measure. This month we'll document a basic strategy for deciding what to measure, and give examples of specific community metrics we've used in practice. Using our knowledge of our community and the goals we previously came up with, we'll make sure the metrics we choose are relevant. read more

You again pick it up only to see another spam SMS. And this goes on, until you choose not get distracted while you are working.

We live in an exciting time. Everyday more things become Internet-connected things. They have sensors and can communicate with other things, and help us perform tasks like never before. Especially at home. read more
