Purism has been working remote since we started in 2014. Here’s our
list of essential free software for remote work, all can be self hosted
or used via various hosted options.
Chat, Calls and Video Conferencing
Team
chat has already become an essential tool for teams looking to be more
collaborative and less reliant on email. At Purism we use Matrix for team chat, 1 to 1 calls, video conferencing via Jitsi
(open source video conferencing), adhoc file sharing and all our
community chat channels. Matrix is a distributed (federated) network,
similar to email, which means you can communicate across Matrix servers
and compatible services.
You can self host Matrix or use a public instance like our own free Librem Chat
service part of Librem One. All the goodness of Matrix conveniently
hosted for you and accessible with one account that also gives you
access to Librem Social, our hosted Mastodon instance, and our premium
services: end-to-end encrypted email and VPN.
Audio Conferencing
We use Mumble
for weekly team calls and general large group audio conferencing. We
really like its low bandwidth requirements and found it scales really
well for our all-hands meeting.
Social
Our primary social channel is on our free Librem Social service powered by Mastodon.
Like Matrix, Mastodon is a distributed (federated) network, so you can
create an account on one of the many public servers or host your own
instance and still communicate across instances. Setting up a private
company Mastadon can be a great way for everyone to share their days. Librem Chat and Librem Social are free service part of Librem One
Forums
In addition to our community chat and social channels we have Discourseforums
for our various products and support. Forums are great for long term
conversations not suitable for chat. If you are new to remote work try
out both team chat and forums to see what works for your team.
Project Management and DevOps
At Purism we have a pledge that all our software and hardware will be free/libre and open source. We host our own GitLab Community Edition instance for our source
code, project management, support and DevOps. GitLab also has powerful
user and group management which makes it easy to work with hundreds of
active community contributors. For PureOS we also host phabricator for ticketing.
Content Authoring and Publishing
Our various web properties use WordPress
for content authoring but we publish static sites for security and
speed. We are looking to migrate to pure static site generators in the
future but WordPress has been an essential tool for us to launch
products and share updates with the community.
Calendar and Files
We heavily use NextCloud internally for our calenders, event scheduling, general file storage and collaborating on documents.
Operating System
At Purism we use PureOS,
our secure GNU/Linux operating system based on Debian. PureOS comes
with many security improvements over a default setup from the average
Linux distribution. There’s support for our TPM chips and Librem Key.
We’ve also enabled AppArmor for more secure apps and we’ve created a
better, safer browsing experience by blocking ads and enforcing HTTPS
everywhere. See the PureOS wiki to learn more about the extensive security features in PureOS.
PureOS is the same operating system we run on our Librem laptops, servers, our recently announced Librem Mini and even on our Librem 5 smartphone. Yes that’s right, the Librem 5 runs a complete desktop Linux experience with access to the same rich app ecosystem.
Other
Most
office-based teams already have email and things like a company
newsletter but we thought we’d share how we manage ours. Our company
email and Librem Mail are powered by Dovecot and we use GNU Mailman for our newsletter and mailing lists. We also have an internal wiki based on wiki.js.
If you’d like to know more about how we work remotely let us know on social, chat or our forums.

Other articles in the ‘difference between’ series: * The difference and compatibility between EV3 and NXT ( link ) * The difference between NXT Home Edition and NXT Education products ( link ) One robotics platform, two targets The LEGO MINDSTORMS EV3 robotics platform has been developed for two different target audiences. We have home users (children and hobbyists) and educational users (students and teachers). LEGO has designed a base set for each group, as well as several add on sets. There isn’t a clear line between home users and educational users, though. It’s fine to use the Education set at home, and it’s fine to use the Home Edition set at school. This article aims to clarify the differences between the two product lines so you can decide which

The STM32 GPIO is blazingly fast and the built-in DMA controller looks powerful enough to handle high bandwidths. So having that in mind, we spent several months perfecting both software and firmware side and here is what we got in the end. Capturing the signals The main challenge when using a microcontroller like STM32 as a core of a logic analyzer is dealing with sampling irregularities. Unlike FPGA-based analyzers, the microcontroller has to share the same resources to load instructions from memory, read/write the program state and capture the external inputs from the G
