Over the past few years I worked different remote setups. I often miss the pair programming fun from my time at Thoughtworks. There are numerous tools you can use for remote pair programming, or a quick get together to work on an issue that is better investigated together. A colleague of mine wrote a blog post how to use a remote tmux session for pair programming a while ago. I recommed this article because it covers most of the basics of what I would need to elaborate here. This is great if you meet together on a dedicated, remote server (with ssh and tmux installed), but what if you just want to share your beloved local dev environment, which your favorite text editor, shell aliases and more with your colleague(s) ? There no place like localhost !

Supervise docker containers with systemd

For my work on Stackspin I’m dealing with Kubernetes a lot, and it’s fun ! However, it’s a super complex monster which can overwhelm you pretty easily. You need to learn a lot of new concepts, and I’m far from fully understanding every component it contains.

Running applications in containers is not only good for isolation but also because containers ship all dependencies bundled, so you don’t need to clutter your host system with dependent (debian) packages. Also, packaging complex applications can be a tiresome work. Saying that I’d like to say Kudos for every packager/ debian maintainer out there who takes on this burden!

Timezones

When you work in a distributed team sometimes it’s hard to find overlapping hours that you can actually work together. Don’t get me even started on the daylight saving madness, when all countries your collegues work in change DST at different moments !

Here are a few small tools that make my life easier.

Displaying local times in differnt timezones

It’s as easy as this:

$ echo "Bogota: $(TZ=America/Bogota date)"
Bogota: Fri Feb 23 05:32:36 -05 2018

I use this little script to have an overview of local times in different locations:

Permanent remote IRC session with tmux and weechat

Sun, 28 Jan 2018 12:19:57 +0100

Internet Relay Chat (IRC) is a popular chat protocol that is widely used in FOSS development. But different timezones and the fact that not everyone is online 24/7 makes communication hard when you have a setup that forces you to quit and re-join the chat frequently (when shutting down your laptop, moving to another location etc.)

It doesn’t make sense to enter a room, ask a question, and leave 3 hours after, before anyone could answer because they are located on the other side of the world and are just waking up.
