7 things I learned from starting an open source project

sam, 01/18/2020 - 09:00

I'm currently involved—heavily involved—in Enarx, an open source (of course!) project to support running sensitive workloads on untrusted hosts. I've had involvement in various open source projects over the years, but this is the first for which I'm one of the founders. We're at the stage now where we've got a fair amount of code, quite a lot of documentation, a logo, and (important!) stickers.

Use this Python script to find bugs in your Overcloud

ven, 01/17/2020 - 09:01

OpenStack stores and manages a bunch of log files on its Overcloud nodes and Undercloud host. Therefore, it's not easy to use OSP log files to investigate a problem you're having, especially when you don't even know what could have caused the problem.

Automating Helm deployments with Bash

jeu, 01/16/2020 - 09:01

Some of our applications are hosted in a Kubernetes cluster, and we use GitLab Continuous Integration (CI) to automate deployments and Helm 2 to deploy our applications. Helm charts enable the storage of templates of Kubernetes object YAML files with variables that can be programmatically set from command-line arguments passed when the chart is used during deployments. This allows us to store critical secrets in GitLab-protected environment variables or in Hashicorp Vault and use them within the CI deployment job.

Why everyone is talking about WebAssembly

mer, 01/15/2020 - 09:01

If you haven’t heard of WebAssembly yet, then you will soon. It’s one of the industry’s best-kept secrets, but it’s everywhere. It’s supported by all the major browsers, and it’s coming to the server-side, too. It’s fast. It’s being used for gaming. It’s an open standard from the World Wide Web Consortium (W3C), the main international standards organization for the web.

6 handy Bash scripts for Git

mer, 01/15/2020 - 09:00

I wrote a bunch of Bash scripts that make my life easier when I'm working with Git repositories. Many of my colleagues say there's no need; that everything I need to do can be done with Git commands. While that may be true, I find the scripts infinitely more convenient than trying to figure out the appropriate Git command to do what I want.

How and why to use Creative Commons licensed work

mar, 01/14/2020 - 09:02

Creative Commons (CC) copyright is a series of copyright licenses that make it easy for creators to share their work and adapt the work of others. Just because something is online doesn’t mean you are free to use it however you like.

How do I know if a work has a CC license?

If you don’t see a Creative Commons license on the work or the creator doesn’t tell you their work is free to use, you cannot use it.

There are three ways to know if a work has a Creative Commons license:
