In 2020, I presented a talk at FrOSCon titled No, we won’t have a video call for that: Communications for distributed teams.

This is a short summary of selected reactions to the original article.

I have a reputation among my colleagues that I am very strict and rigid about the communications rules I follow for myself, and for my team.

Over time I’ve come to accept that one of the things I’m apparently reasonably competent at is writing and publishing ads for open positions, and I’ve received questions and requests for advice from other folks who hire people.

We are in year 2 of the Covid-19 pandemic, and open-source conferences are still, for the most part, online-only events.

FrOSCon 2021 was again an online event due to the COVID-19 pandemic (just like the previous year), and had a track named Woodwork instead of IT, showcasing people’s hobbies and interests they had discovered, or rediscovered, during lockdown.

If you are spending a non-trivial amount of time in video calls every week (something that, at the time of writing, is true for a lot of people due to the COVID-19 pandemic), and also having to use mains-powered artificial lighting in your office (true at…

One of the non-open-source applications I sometimes have to run for work purposes, and which out of principle I run in LXC containers, is Zoom.

Some of the X applications I run in LXC make sounds.

I occasionally want to run X applications in an LXC container.

LXC is part of my standard Linux desktop toolbox, and I use it daily.

This is a talk I submitted1 to linux.conf.au 2021.

This is a talk of which I had done a previous version at Open Infra Days Nordic in 2019, but where unfortunately the audio came out really messed up in the recording.

I’ve been wanting to speak at PyCon.au for a long time now, and finally did for the 2020 PyConline AU edition.

These are the slides and recordings of the original talk that ultimately became this article.

FrOSCon 2020 was an online event due to the COVID-19 pandemic, and gave me the opportunity to present an extended and heavily updated version of my DevOpsDays 2019 talk.

Asynchronous Celery tasks that manipulate a MySQL/Galera database from a Django application can produce very interesting behavior when HAProxy is involved.

Recently I came across a tweet from my Irish OpenStack community friend Dave Neary, in which he wondered aloud why a picture, which was very obviously (and poorly) doctored, made its way onto Twitter.

In my now almost 10ish years of first running my own company, and then managing a team in the company I sold my company to, I have very frequently struggled with what’s a “fair” way of paying people.

Sometime last year I came across a post on /r/food that I seem to be unable to dig up.

This is my look back at the decade we’re just finishing up.1 Some stats Besides managing to grow 10 years older, in this decade I founded 1 company, sold 1 company, left 1 company, joined 1 company, folded 0 companies, bankrupted 0 companies, raised preci…

I’ve found this to be the pan pizza to end all pan pizzas.

This year, DevOpsDays Tel Aviv accepted two of my submitted talks: No really, don’t chuck everything in Slack: Communications for distributed teams This is a 40-minute talk that I presented after keynotes on day 2.

I’ve been doing public talks and presentations rather frequently for the last 10-or-so years, but this year I made significant changes to my process for creating, rehearsing, and presenting talks.

So you’re running a Ceph cluster, and you want to create pools using erasure codes, but you’re not quite sure of exactly how much extra space you’re going to save, and whether or not that’s worth the performance penalty?

When you are using functionality that is buried deep in the Linux kernel, ftrace can be extremely useful.

This is a talk I submitted1 to three separate conferences: PyCon AU 2018, via an anonymized CfP process using PaperCall.

I’ve run a distributed team — nominally the same team, though through people joining and leaving I am the sole original band member at this point — for almost 8 years.

In a Python command-line interface (CLI) utility, you will want to inform your users about what your program is doing.

I have no experience with, and presently no plans for, running or organizing a grassroots knowledge-sharing conference.

This is a talk I submitted1 to Write The Docs Prague, September 15-17, 2019.

I have spoken at tech conferences for the better part of a decade, and up to this point I have only ever published my talks after I’ve actually presented them.

The excellent Josh Simmons recently implored people on Twitter1 to stop using the term “non-technical” when talking about another person’s skill set.

“I can’t figure out how upload filters should work, but I’m not a technical person — surely someone who is can sort it out!”

On Tuesday, March 26 at half-past noon Central European Time, the European Parliament is due to vote on an issue that will definitely impact your life, no matter if you live in or outside the EU.

If you ever write unit tests in Python, you are probably familiar with Ned Batchelder’s coverage tool.

If you’ve ever built a command-line interface in Python, you are surely familiar with the argparse module, which is part of the Python standard library.

Neutron quotas As with all other OpenStack services, Neutron uses a fairly extensive quota system.
