Mosquitto Unikernel using OSv and Capstan

Some time ago, I wrote a blog post about Unikernels and was quite enthousiast about the combination of OSv and XenServer. I had Cassandra running in an OSv container in a Jiffy and think Unikernels on hypervisors are quite better to manage and maintain than Docker images. If you want to know more about why I think they could be considered the successor of Docker, please do feel free to read my blog “Minimalist Cassandra VM using an OSv Unikernel“. In this blog I have written about my journey to get a unikernel Cassandra running, but I’m also trying to outline the pros and cons of…

Arduino programming on the ESP8266

The ESP8266 has been gaining quite some popularity in the Internet of Things space. It is affordable and tiny and has multiple programming options. You can use Lua or C code to program the chip and it can virtually do anything you can also do with an Arduino. Some folks in the ESP8266 community have been debating about how great it would be if there were a third programming options. The ESP8266 should be made compatible with Arduino code! Richard Sloan and Ivan Grokhotkov eventually stepped to the plate and did the work to add the ESP8266 as a board to the Arduino…

New version of the NodeMCU board

I never really liked the NodeMCU, because the board was too fat. If you stick it into a breadboard, you’ll basically cover the entire breadboard and you’ll not be able to wire it up anymore. However, there’s a new version available now, which is an absolute blessing. On a breadboard, it still leaves a row on both sides uncovered, so that you can very easily wire it up to sensors and actuators. With this, I really like the NodeMCU to experiment with. With a price of $6, it is hardly any more expensive than a bare ESP8266 module and save…

Impressions from the Moroccan Bazaar Beverwijk

The Bazaar in Beverwijk is the largest covered market in Europe. There are several market halls, such as the ‘Black Market’, ‘Oriental Market’ (better known as the Moroccan Bazaar Beverwijk in my family), ‘Grand Bazaar’, ‘Computer Market’ and ‘Flea Market’. The Bazaar also has its own ChinaTown. The markets are packed with antiques, curiosities, books, shoes, trendy clothing, car parts and fruit and vegetables. ChinaTown has 180 shops as well as restaurants and wholesalers. Last weekend Haseenah​ and I spent some time shopping shopping for my sister-in-law’s new house at the Moroccan Bazaar Beverwijk. After just snapping away here and…
