Microsoft NTP servers suffer hiccups

Sometime on the morning of April 3, Microsoft’s Network Time Protocol (NTP) servers went haywire. At first, Microsoft’s NTP server (time.windows.com) reported the time being an hour later than it should have been. Then, the site went offline. Finally, 24 hours later, the time server came back online with the right time.

What is Chef? A primer for DevOps newbies

Chef is an open source cloud configuration management and deployment application. It’s meant to help anyone orchestrate servers in a cloud or just in a departmental data center. Instead of system administrators sweating over management programs that were designed for single, stand-alone servers, Chef allows DevOps to spin off dozens or hundreds of server instances in less time than it takes you to read this article.

Chef enables programmers and system administrators to work together. Instead of developers writing applications and then waiting on Ops staff to figure out how to deploy the software, Chef serves both communities. Chef moves the process from a herky-jerky release cycle to a continuous delivery model by enabling an effective and automated workflow—a central goal of the DevOps movement.

Net result? You get more work from your existing IT crew, and everything in IT moves faster with fewer errors. When defects do crop up (because this is the real world), they get fixed sooner.

Chrome browser’s ‘secure’ isn’t the same thing as ‘safe’

Google takes web security seriously. When the Google Chrome web browser encounters a payment site without Secure Socket Layer (SSL)/Transport Layer Security (TLS) encryption, it marks as insecure. Soon, Chrome will mark any HTTP site as insecure. That’s great, but just because a site is tagged ‘secure’ doesn’t mean it’s safe.

Ubuntu switches to GNOME desktop and gives up smartphone hopes

Some of you may have been surprised when Canonical‘s founder Mark Shuttleworth announced Ubuntu Linux was ending its “investment in Unity8, the phone and convergence shell.” I wasn’t. Ubuntu had long been a cloud power and it’s been building its Internet of Things (IoT) reputation. Shuttleworth and his executives finally decided to play to the company’s strongest suit.

Sorry Windows, Android is now the most popular end-user operating system

For decades, the answer to the question “What’s the most popular operating system?” was Windows. You may not have liked it, but macOS, OS/2, Linux, you name it, couldn’t knock it off its pedestal. But, then along came smartphones and tablets, and PCs started their long sales decline. In March 2017, by web-analytics company StatCounter’s reckoning, Android became more popular than Windows.

Linux Foundation offers Hadoop training

The popular big data program Apache’s Hadoop is difficult to use. Indeed, Datanami, an important big data publication, recently found that “the Hadoop dream of unifying data and compute in a distributed manner has all but failed in a smoking heap of cost and complexity”. One reason? “It’s just a very complicated stack to build on.”

One answer: Educate developers. That’s where The Linux Foundation comes in with its latest massive open online course (MOOC): LFS103x — Introduction to Apache Hadoop.

Google presents its open-source goodies to the world

Google lives and dies on open-source software. Without Linux, there would be no Google. The company both uses and makes open-source code every day of the year. In 2017 alone, Google has open-sourced Chrome for iOS; Upspin file-sharing; E2EMail, experimental end-to-end email encryption; and the Guetzli JPEG encoder. There’s only one problem. How do you find all these projects? Google finally has given us the answer: Google Open Source Projects.
