Hi there! I'm Remy, a developer with a focus on C++, C, some C#, Linux and embedded systems.

I currently work on a C++ and Qt stack running on Yocto Linux. It controls hardware, runs the UI and has a few utilities for IoT connectivity and configuration. Technology includes Microsoft Visual C++ (MFC), .NET (Framework, C++/CLI and Core), Flash, Qt and ARM kernel drivers.

I've been a Linux/UNIX sysadmin for over 10 years; I've built high-available cloud environments in OpenStack, Azure or on premise, with Ansible, Chef, Puppet and Terraform (but can work with any other configuration management tool). My sysadmin keywords are OpenStack, cloud, virtualization, high-availability, scaling and clustering, security, (Open)SSL, Python, Powershell, bash and general linux/UNIX system administration.

I've worked in a devops role for the Erasmus University Medical Center (a large hospital and medical university in Rotterdam), Digidentity (a Dutch certificate authority, the company that develops DigiD and other Ruby on Rails applications), CloudVPS (an OpenStack cloud provider), VolkerWessels (as an Azure cloud specialist) and a few other smaller companies.

I'm a team player that loves to work with configuration management tools and version control systems. If I do something more than three times, I automate it. Planning, documentation, monitoring and backups are things I do first, not when the time allows it later. Last but not least I have an interest in legacy systems like the PDP-11, PDP-8, OpenVMS, HP-UX and old UNIX systems.

This is my personal website, please do note that these articles do not reflect or are based on work, opinions or policies of any of my (previous) employers. Any resemblance to reality is pure coincidence.

This site started in 2006 as my form of (public) documentation. It has grown to include software, guides, snippets and articles on linux/UNIX, programming, system administration and everything related with over 10.000 unique visitors a day as of 2018-06. The URL is the phonetic way you say my name (Ray-Mii), since non-Dutch speakers always have trouble with the correct pronunciation.

If you want to send me feedback, emails or comments, see below for the contact details.


If you want my full resume including all (previous) jobs, experience and education, please send me an email.


You can reach me by email, try mailing "contact" "at" "relst" "dot" "nl". I'm not on any social networks, not on Facebook, not on LinkedIn, not on twitter, IRC, mastodon, etc. Every profile on a social network claiming to be me is false.

In the past this page also had a GPG and S/MIME key for secure email. I removed that because the usage was so low compared to the maintenance efforts.
