After downloading a fresh version of a Fedora ISO, it is a good habit to get in to to verify the downloaded file. The benefits of verification are two-fold: integrity and security. Verification of your ISO confirms if the file... Continue Reading →

Sometimes, you may want to combine two files in a way that the output makes even more sense. For example, there could be a file containing name of continents, and another file containing names of countries located in these continents, and the requirement is to combine both files in a way that a continent and the corresponding country appear in the same line.

While the options for Linux computers from commercial vendors are still needles in the proverbial haystack of OEM Windows equipment out there, there are more and more options available to a consumer who wants a good, solid device that's ready-to-use with no messing around. Still, there are more Linux OEM computers than I could look at for one article—and the options tend to be different in Europe than they are in the United States, with providers like Entroware that don't ship to the latter at all.

In most situations, from getting clothing advice to seeking peer review of the next scientific discovery, we harness the help of people around us in order to discuss and analyze potential next steps. Hardly anyone thinks up a perfect solution right off the bat; it's an iterative process full of trials and errors, adjustments, and new experiments. And it's a process we can always improve. This chapter offers some advice for doing just that. What are feedback loops? Feedback loops are supposed to be great and solve all sorts of problems. So what are they, exactly? read more

Our survey also reveals that a majority of Americans do not trust the government to protect Internet access?

In Part 1 of our series, we installed Docker, Minikube, and kubectl. We also got an image repository running on our cluster in Minikube, and tested the process of building and pushing an image using our Hello-Kenzan app.

Even though I write for a living, I rarely use a word processor these days; I do most of my work in a text editor. When I do need to use a word processor, I turn to LibreOffice Writer. It's familiar, it's powerful, and it does everything that I need a word processor to do. read more

If you really want to nail down your server, you use SELinux. This makes the newly discovered Linux security hole -- with the sudo command that only hits SELinux-protected systems -- all the more annoying. Ironically, only the most secure Linux server setups are vulnerable to this newly discovered hole.

There are numerous approaches to writing documentation, but one of the fundamental distinctions a doc writer must make is whether the resulting doc's goal is to: Describe "features" of a product, software, solution, etc., and how to use these features, or Explain what actions to take in order to perform a task to achieve a specific goal Both approaches have valid uses, but there are areas or use cases where one is better than the other. It can also depend on who is writing the documentation and who is the intended audience. read more

Happy 19th anniversary of the 1.0 release of GIMP! Let me legally buy you a drink (well, in Canada that is). There are certainly many things to celebrate. Hoorah! Like other young professionals, I have worked many odd jobs over the years, slowly spinning my strange and broad range of experience into a neatly packaged service. Dabbling in open source editing and design software was once a hobby. Now, I use GIMP every day. read more
