Shuah Khan becomes the third Linux Foundation Fellow

Programmers love to write code. But what about debugging it, writing test suites, and tracking down security bugs? Not so much. To help address these problems in Linux, Shuah Khan, a noted Linux kernel developer, is becoming — after Linus Torvalds and Greg Kroah-Hartman — the Linux Foundation‘s third Linux Foundation Fellow.

Open Distro for Elasticsearch is Amazon’s move to show it’s pro-open source

Amazon Web Services (AWS) just launched Open Distro for Elasticsearch. This program takes AWS’s recent proprietary additions to Elasticsearch and open sources them under the Apache 2.0 license. That sounds good.

Shay Banon, co-founder of Elasticsearchand CEO of Elastic, its parent company, sees Amazon as forking and redistributing rebundled Elasticsearch for its own purposes: “From various vendors, to large Chinese entities, to now, Amazon. There was always a ‘reason,’ at times masked with fake altruism or benevolence” for “open-sourcing” their own Elasticsearch forks.

What’s the difference between containers and virtual machines?

I was at a conference recently when I realized the person I was talking with thought that containers were just smaller versions of virtual machines (VM). Ah, no. No, they’re not.

Yes, they can function in the same ways from a practical viewpoint. For example, they’re both commonly used to run server applications. How they do that is where things start to be different between them. This, in turn, leads to them being good for different kinds of IT jobs.

Open source advances deeper into hardware: The CHIPS Alliance project

Open-source hardware is older than you might think. Sun released OpenSPARC in 2007, and IBM started OpenPOWER in 2013. OpenSPARC would die after Oracle bought Sun, and OpenPOWER remains largely IBM-driven. With the recent arrival of the RISC-V (pronounced Risk-Five), though, open-source CPU designs have finally caught fire. Now, the Linux Foundation is helping form the CHIPS Alliance project. CHIPS, in turn, will host and curate high-quality, open-source silicon device design code.

CoreDNS: The DNS for cloud-native computing

I have a t-shirt which reads, from top to bottom: “It’s not DNS. There’s no way it’s DNS. It was DNS!” As every sysadmin knows, all too many network problems boil down to a Domain Name System (DNS) blunder. That’s already annoying, but when you have to deal with a DNS headache with fast-moving containers and cloud-native computing, DNS problems reach migraine headache levels of pain.

A double shot of aspirin answer to this pain is CoreDNS. This is a new DNS server that was designed expressly to be extensible, fast, and flexible. In short, it’s just what’s needed for containers and cloud-native computing.
