My BGP training course keeps evolving over two decades

On October 29, 2003, I did my first BGP training course for NL-ix . A lot has remained the same over the intervening 20+ years, but also a lot has changed.

Stroomprijs drie uur lang onder de -20 cent/kWh, dus zoveel mogelijk elektriciteit aan het verspillen! @lennardpoel

@[email protected] #yay 6000 stappen is niet slecht maar. vraag me wel af of het klopt: meer gefietst dan gewandeld.

This image is a good reflection of the visibility of the #EuropeanElections campaign here in the Netherlands... Remember, vote early, vote often! And we are the earliest, voting tomorrow.

June 3 I’ll be teaching a course about #BGP course at the NL-ix office in Zoetermeer. This course will be in English (maar kan natuurlijk ook in het Nederlands!) See here for more information: https://www.nl-ix.net/articles-events/event/bgp-course/

I you can’t make it to Zoetermeer but still need to learn some #BGP, let us know and we’ll see about a remote course in the future.

Enjoy today's eclipse, American friends! Was in Oregon for the last total eclipse back in 2017, and it was amazing. I do need some more practice photographing the phenomenon, tough.

Hey @siracusa, I'm definitely in favor of the aspect ratio matching the image rather than make the image match an arbitrary preselected aspect ratio: http://www.iljitsch.com/2017/eclips2017en/ From the evidence it seems Christopher Nolan is in the same camp. That said, have you tried using the shift key as you resize?
