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

I currently work for De Jong DUKE were I develop software for an embedded platform that powers coffee machines. This is a C++, C and Qt stack runningon Yocto linux and Nucleus RTOS. It controls hardware, runs the UI and has a few utilities for IoT connectivity and configuration. Technology is mostlyC++ but includes Microsoft Visual C++, 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 and Terraform(or any other configuration management tool). My sysadmin keywords areOpenStack, cloud, virtualization, high-availability, scaling and clustering,security, (Open)SSL, Python, Powershell, bash and general linux/UNIX systemadministration.

I've worked in a devops role for the Erasmus University Medical Center (alarge hospital and medical university in Rotterdam), Digidentity (a Dutchcertificate authority, the company that develops DigiD and other Rubyon Rails applications), CloudVPS (an OpenStack cloud provider), VolkerWessels (as an Azure cloud specialist) and a few other smallercompanies.

I design, build, document and manage large, complex and high-available systems.I'm a team player that loves to work with configuration management tools andversion control systems. If I do something more than three times, I automate it.Planning, documentation, monitoring and backups are things I do first, notwhen the time allows it later. Last but not least I have an interest in legacysystems 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 reflector 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 toinclude software, tutorials, snippets and articles on linux/UNIX, systemadministration and everything related with over 10.000 unique visitors a day asof 2018-06. The URL is the phonetic way you say my name (Ray-Mii), sincenon-Dutch speakers always have trouble with the correct pronunciation.
