DevOps is for everyone

Wednesday 21st of November 2018 08:00:00 AM

I've never held a job as a developer nor in operations—so what am I doing writing an article about DevOps? I've always been interested in computers and technology.

How do we handle and use such enormous amounts of data?

Tuesday 20th of November 2018 08:01:00 AM

How many gigabytes of data did we (the people of Earth) create yesterday?

...brain. is. thinking...

More than 2.5 billion!

And it's growing. Yes, it's hard for us to wrap our human brains around it. So, the question the Command Line Heros podcast deals with this week is: How do we handle and use such enormous amounts of data?

More and more data is mind-boggling but also exciting. We have the potential to do so much with so much data... with computers doing the hard work.

Give your students edit access to their course syllabus

Tuesday 20th of November 2018 08:00:00 AM

It's also become a prime opportunity for me to introduce freshman students to the guiding principles of open culture.

I've developed a method for treating my class as an open organization. To create a more collaborative and inclusive environment, I let the students co-construct the official course syllabus.

How old were you when you first started using Linux?

Friday 16th of November 2018 08:02:00 AM

Some folks grew up on Linux. But for most of us, we started using it later in life.

Whether you switched from another operating system, or are one of the lucky few who knew no OS before it, all of us were beginners at some point.

How old were you when you started using Linux? Do you remember that time clearly, or is it so far in the past that it's but a faint memory?

Regardless of the answer, let us know when it was, and maybe, a bit about what that experience has meant to you.

How to install a device driver on Linux

Thursday 15th of November 2018 08:02:00 AM

One of the most daunting challenges for people switching from a familiar Windows or MacOS system to Linux is installing and configuring a driver. This is understandable, as Windows and MacOS have mechanisms that make this process user-friendly. For example, when you plug in a new piece of hardware, Windows automatically detects it and shows a pop-up window asking if you want to continue with the driver's installation. You can also download a driver from the internet, then just double-click it to run a wizard or import the driver through Device Manager.
