• Crossbar / WAMP <jun 25, 2019>

  I am currently experimenting with Crossbar.io, a micro-service platform based on the Web Application Messaging Protocol (WAMP). It support Publish/Subscribe and Remote Procedure Calls (RPCs). WAMP client libraries are available in 15 languagues, including my favorites Python and Javascript (but also Java, PHP and C#).

  So far it has been a positive experience. The biggest hurdle is getting the authorization configuration right. But once that is done, adding end points is straight-forward.

• Pony ORM <jun 25, 2019>

  Up till now I have been using SQLAlchemy as my ORM outside Django. By SQLAlchemy is highly technical and sometime archaic in its use. I wrote SQLAngelo to help fix this, but had always wanted to explore other options.

  So, for my latest project I decided to try Pony ORM again. And this time I like it. It is much simpler than either SQLAlchemy or Django ORM. Maybe that means it is less powerful, but so far I have not encountered limitations.

• React <jun 25, 2019>

  For my latest projects I have been using React for the client. So far, these are the components I am using:

  • Blueprint as UI toolkit, as I am tired of Bootstrap UIs. It is extensive, elegant en well documented. I also tried Evergreen but found it too limited.
  • Autobahn for WAMP programming.
  • Redux for managing state.
  • Grid Layout for interactive graphics and drag 'n' drop.
  • Luxon for dates and times.

• fullstek <jun 26, 2019>

  Today I visited a local Meetup where I got to experiment with Bluetooth Low Energy (BLE) using noble. It was good to discover how elegant a event-driven interface to a wireless device can but. Unfortunatley, I did not get it to work properly (it ran, bu I did not get any messages from the device).

  Maybe I'll try again later.
