What is Istio?

Friday 21st of September 2018 07:00:00 AM

One of the key metrics or performance indicator of a microservices software architecture and environment is lead time (the amount of time it takes to get from idea to production). Many things have an impact on lead time, such as decision-making time, how quickly the code can be implemented, testing, continuous integration, etc.

[This is part one of my ten-part Introduction to Istio series, originally published on Red Hat Developers.]

Who will push back the most on a move to DevOps?

Thursday 20th of September 2018 07:00:00 AM

You're moving to a DevOps model for all or part of your organisation: well done! Somebody, somewhere has made the leap. Let's assume, for the sake of this article, that you have management buy-in: whatever hurdles needed to be jumped, whatever mountains needed to be climbed to get that momentous "Yes."

Linux firewalls: What you need to know about iptables and firewalld

Tuesday 18th of September 2018 07:01:00 AM

This article is excerpted from my book, Linux in Action, and a second Manning project that’s yet to be released.

The firewall

A firewall is a set of rules. When a data packet moves into or out of a protected network space, its contents (in particular, information about its origin, target, and the protocol it plans to use) are tested against the firewall rules to see if it should be allowed through. Here’s a simple example:

How selfless is your open organization?

Tuesday 18th of September 2018 07:00:00 AM

"Community" is a defining characteristic of open organizations. A community could be many things—a "team," a "group," a "department," or a "task force," for example. What makes any of these groups a true community is two distinct factors: a well-defined purpose and clear investment in or value of that purpose.

Did your open source career begin with video games?

Tuesday 18th of September 2018 07:00:00 AM

Certainly you don't need to be a gamer as a child to grow up and become a developer, nor does being a gamer automatically set you up for a career in technology.

But there's definitely a good bit of overlap between the two.

4 scanning tools for the Linux desktop

Monday 17th of September 2018 07:02:00 AM

While the paperless world isn't here quite yet, more and more people are getting rid of paper by scanning documents and photos. Having a scanner isn't enough to do the deed, though. You need software to drive that scanner.

But the catch is many scanner makers don't have Linux versions of the software they bundle with their devices. For the most part, that doesn't matter. Why? Because there are good scanning applications available for the Linux desktop. They work with a variety of scanners and do a good job.

How gaming turned me into a coder

Monday 17th of September 2018 07:01:00 AM

I think the first word I learned to type fast—and I mean really fast—was "fireball."

Like most of us, I started my typing career with a "hunt-and-peck" technique, using my index fingers and keeping my eyes focused on the keyboard to find letters as I needed them. It's not a technique that allows you to read and write at the same time; you might call it half-duplex. It was okay for typing cd and dir, but it wasn't nearly fast enough to get ahead in the game. Especially if that game was a MUD.

Folding@Home Performance Is Looking Good On The GeForce RTX 2080 Ti

Yesterday I published a number of CUDA and OpenCL benchmarks for the NVIDIA GeForce RTX 2080 Ti graphics card that happened to show the very strong GPU compote potential for this new Turing GPU. Another workload with promising potential for this powerful but pricey graphics card is Folding@Home. Folding@Home was accidentally left out of yesterday's RTX 2080 Ti CUDA/OpenCL comparison with simply forgetting to add the FAHBench test profile to the run queue. But as there is often interest in seeing the FAHBench performance on new GPUs by at least a few of the premium enablers, I ran some extra tests just looking at the Folding@Home performance and here are those results today.
