I've been writing since I had my first pen and a notebook. I've played with open-source software since I had my first computer. Now I apply these skills to making the world a better and more exciting place.

I’m going to try making a podcast

I spend a lot of time thinking about the nature of my profession and the people I work with. Now, I’ve created a podcast so I have an excuse to talk to those people, ask all sorts of questions, and share interesting parts of the work! Write Open Source is going to be a behind-the-scenes…More

Ed offer tools, original articles, and other resources that will provide helpful financial information to members of the disabled community.  Ed says, “Many people are unaware of just how many options they have when it comes…More

Command ‘brew’ not found

Let me guess: you just installed Homebrew on your Linux system because you were going to use it to install some other software. Instead, when you tried to install the software, you got something like this: This response means the command can’t find the brew application binary. This happened because the Homebrew installation omits an…More

minikube ugh! microk8s yay!

I just spent hours trying to get minikube up and running on Linux Mint 20.2 Cinnamon. Endless installation and dependency problems (even though I’ve installed it on other platforms in the past). Finally, I installed microk8s using snap. No problem. rolfedh@rolfedh-HP-Z2-Mini-G3-Workstation:~$ microk8s status microk8s is running high-availability: no datastore master nodes: 127.0.0.1:19001 datastore standby nodes:…More

Vale: The unexpected team

The past two weeks, I created a Slack channel called #vale-at-red-hat and invited folks at work to join. Then I invited them to become collaborators on the repo. It worked! A bunch of folks signed up to become full collaborators. To work this way, you have to give up sole ownership and control. Invite folks…More

Vale notes #3: Things start rolling

Last week, I did separate walk-throughs with two writers. My intention was to gain insight into the issues a typical user might encounter, and to use that information to improve the “getting started” repo I had created. I helped them install, configure, and start using Vale on their systems. Installing Vale by using brew was…More

Vale notes #2: Talk to experts and stakeholders

In addition to eating my own dogfood, I started finding and talking to experts and stakeholders. For experts, I went to folks inside and outside Red Hat. At Red Hat, I talked to Fabrice Flore-Thebault and Yana Hontyk. Last year, they presented on using Vale with their documentation sets: Eclipse Che and CodeReady Workspaces. I…More

Vale notes #1: Eating my dog food

I’ve heard complaints about the peer review process at a variety of organizations where I’ve seen it in use. To simplify, they sound like this: Writers: When I fix a set of issues and resubmit the PR, the reviewer(s) come up with a new set of issues. Reviewers: I keep flagging the same set of…More
