10 resources every sysadmin should know about

Monday 22nd of July 2019 07:03:00 AM

Everybody knows that sysadmins are impossibly busy people. Consequently, it sometimes seems they are superhuman. The sysadmin's dirty secret, the same one shared by many open source users, is that they don't actually do all of the work it looks like they've done. One of the greatest tools in the sysadmin's kit is their ability to reuse work someone else has already done for them.

Buying a Linux-ready laptop

Friday 19th of July 2019 12:22:00 PM

Recently, I bought and started using a Tuxedo Book BC1507, a Linux laptop computer. Ten years ago, if someone had told me that, by the end of the decade, I could buy top-quality, "penguin-ready" laptops from companies such as System76, Slimbook, and Tuxedo, I probably would have laughed. Well, now I'm laughing, but with joy!

Redirect a GitHub Pages site with this HTTP hack

Thursday 18th of July 2019 07:01:00 AM

I run a few static websites for my private projects on GitHub Pages. I'm absolutely happy with the service, as it supports custom domains, automatically redirects to HTTPS, and transparently installs SSL certificates (with automatic issuing via Let's Encrypt). It is very fast (thanks to Fastly's content delivery network) and is extremely reliable (I haven't had any issues for years).

How to apply 'release early, release often' to build a better brand

Thursday 18th of July 2019 07:00:00 AM

The importance of open source—and specifically the maxim "release early, release often" (RERO)—can hardly be overstated. 

This approach born at the command line has impacted the world as organizations of every shape and size discover what open, collaborative processes can do. Look around. The evidence is everywhere: on our phones, in our cars, in schools and hospitals.

If we still built software the way we used to, innovations across these and countless other areas may never have seen the light of day.

Start tinkering with the Circuit Playground Express

Wednesday 17th of July 2019 07:02:00 AM

I've been a gadget person as long as I can remember, so I was delighted when I discovered an Adafruit Circuit Playground Express (CPX) in the swag bag I got at PyConUS in May. I became fascinated with these little devices last year, when Nina Zakharenko highlighted them in her All Things Open presentation, Five Things You Didn't Know Python Could Do, with Python-powered earrings.

JSON stands for JavaScript Object Notation. This format is a popular method of storing data in key-value arrangements so it can be parsed easily later. Don’t let the name fool you, though: You can use JSON in Python—not just JavaScript—as an easy way to store data, and this article demonstrates how to get started.

Become a lifelong learner and succeed at work

Tuesday 16th of July 2019 07:00:00 AM

Continuous learning refers to the ongoing, career-driven, intentional learning process people undertake to develop themselves. For people who consider themselves continuous learners, learning never stops—and these people see learning opportunities in everyday experiences. Engaging with one's colleagues in debate, reflecting on feedback, scouring the internet for a solution to a frustrating problem, trying something new, or taking a risk are all examples of the informal learning activities one can perform on the job.

What is POSIX? Richard Stallman explains

Monday 15th of July 2019 07:02:00 AM

What is POSIX, and why does it matter? It's a term you've likely seen in technical writing, but it often gets lost in a sea of techno-initialisms and jargon-that-ends-in-X. I emailed Dr. Richard Stallman (better known in hacker circles as RMS) to find out more about the term's origin and the concept behind it.

Understanding software design patterns

Monday 15th of July 2019 07:01:00 AM

If you are a programmer or a student pursuing computer science or a similar discipline, sooner or later, you will encounter the term "software design pattern." According to Wikipedia, "a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design." Here is my take on the definition: When you have been working on a coding project for a while, you often begin to think, "Huh, this seems redundant.

MTTR is dead, long live CIRT

Friday 12th of July 2019 07:02:00 AM

The game is changing for the IT ops community, which means the rules of the past make less and less sense. Organizations need accurate, understandable, and actionable metrics in the right context to measure operations performance and drive critical business transformation.

The more customers use modern tools and the more variation in the types of incidents they manage, the less sense it makes to smash all those different incidents into one bucket to compute an average resolution time that will represent ops performance, which is what IT has been doing for a long time.
