I wrote about how Canonical's IP policy claims that you're violating their copyright if you distribute containers built on modified Ubuntu images - +Dustin Kirkland called that "sensationalist and untrue". I spent a few minutes yesterday talking to Mark Shuttleworth, who made it very clear that Canonical believe they hold copyright over their binaries and require you to ask their permission to do anything other than distribute unmodified images.

Since that's what their policy actually says, that's not surprising. What was more surprising was that he was perfectly willing to admit that their policy is deliberately unclear and overreaching because that increases the number of people who will pay them rather than risk a lawsuit.
I bumped into Mark Shuttleworth today at Linuxcon and we had a brief conversation about Canonical's IP policy. The short summary: Canonical assert that the act of compilation creates copyright over the binaries, and you may not redistribute those binaries unless (a) the license prevents ...

Canonical have improved their IP policy such that it no longer violates the GPL, but it's still awful. Tldr; don't build a product on top of Ubuntu 
(In order to avoid any ambiguity here, this is a personal opinion. The Free Software Foundation's opinion on this matter is here) Canonical have a legal policy surrounding reuse of Intellectual Property they own in Ubuntu, and you can find it here. It's recently been modified to handle concerns ...

A bunch of people have misinterpreted some excellent security research work as evidence of a widespread firmware backdoor, but that doesn't mean that there's no threat.
This is currently the top story on the Linux subreddit. It links to this Tweet which demonstrates using a System Management Mode backdoor to perform privilege escalation under Linux. This is not a story. But first, some background. System Management Mode (SMM) is a feature in most x86 processors ...

Here's a video of a talk I gave two weeks ago at Sesja Linuksowa in Wroclaw, Poland. It's about containers and +systemd​, in particular where nspawn/machined/importd fit into the big picture, and what we actually intend to turn it into.

As someone who recently spent five minutes looking for Google Calendar while on the phone, I wholeheartedly agree with this.

Why doesn't Red Hat Enterprise Linux, Fedora, Centos want docker to be run directly by non root users? I have been receiving bug reports on why we don't allow docker to be run as a non root users?...

If only I had read this earlier... like 6 years ago :-)
Use the Unofficial Bash Strict Mode (Unless You Looove Debugging). First published in Aaron Maxwell's Newsletter. Let's start with the punchline. Your bash scripts will be more robust, reliable and maintainable if you start them like this: #!/bin/bash. set -euo pipefail. IFS=$'\n\t' ...

But, but, but... MongoDB is fast! ;-) Breathtaking read. Via +Daniel Lobato 
In May of 2013, we showed that MongoDB 2.4.3 would lose acknowledged writes at all consistency levels. Every write concern less than MAJORITY loses data by design due to rollbacks–but even WriteConcern.MAJORITY lost acknowledged writes, because when the server encountered a network error, ...

I see more and more projects doing the "curl | sudo bash" method of installing something.  Not good on huge number of levels.  This is a good rant of people doing this for containers.

Yes, I know docker doesn't support signed images yet, hopefully that will happen someday...
None of these "fancy" tools still builds by a traditional make command. Every tool has to come up with their own, incomptaible, and non-portable "method of the day" of building. And since nobody is still able to compile things from scratch, everybody just downloads precompiled binaries from ...
