The third #TRON film in 43 years is coming up! The first two should be delivered as 4K UHD blu-ray any time now. I once worked on a software project where I named one process the "master control program". The business people just nodded, the nerds laughed behind their beards.

In an interview with @nl_ix I tell my "origin story": how I discovered the #BGP protocol which I've been configuring, writing about and teaching about for 30 years! nl-ix.net/about/who-is-nl-ixโ€ฆ Upcoming: Rotterdam (Dutch) June 16th, online (English) June 23rd nl-ix.net/articles-events/evโ€ฆ

A million prefixes? Well, Iโ€™ve had a few of you point out that 1,000,000 isnโ€™t 1,048,576 (2^20) and that neither exact number really means anything dramatic because RIB/FIB logic is different between chip makers. However, 1,000,000 is a real bell-weather point. Beware the future!

Hoe is het mogelijk dat dit land geregeerd wordt door de veevoerlobby!?! Eenmanspartij PVV interesseert het natuurlijk niks, maar hoe kunnen VVD en NSC zich zo laten inpakken??

Take note, our American friends, this is how you do it.
Marine Le Pen, the French far-right leader, has been convicted of embezzlement and sentenced to 4 years in prison. She has been barred from running for public office for 5 years. Bravo, France for doing what the U.S. could not! ๐Ÿ‡ซ๐Ÿ‡ท

Tweede-kamerdebat over #stikstof kijken is geen lolletje. De vaagheid van @lientje1967 overtreft de overige vaagheid/ellende ruimschoots. Maar wellicht dat de minister met nep-wenkbrauwen dit nog gaat overtreffen. #wehebbenteveelboeren

.@liesbethstaats Naar aanleiding van je vraag aan Bert Hubert over alternatieven voor de cloud: de rijksoverheid heeft VIER overheidsdatacenters die de meeste van deze dingen gewoon zelf kunnen. Als ambtenaar 2016-2019 ergerde ik me dood aan het gebrek aan nadenken hierover.

Als ik nu over mijn monitor naar buiten kijk zie ik een lichtmast van de voetbalclub op zo'n 60 meter afstand. KPN gaat hier een stel antennes voor mobiele telefonie plaatsen. Goed of minder goed plan voor mij?

You know what? I'm thinking the dems are going to take Texas in November. It's going to be epic.

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.

Het verschil is dat we in principe willen dat mensen meer kranten lezen/kopen, maar minder gas gebruiken.
De krant wordt inderdaad 11% duurder. Niet mijn favoriete maatregel Maar ik heb wel de advertentie van D66 gemist waarin ze trots vertelden dat ze de belasting op aardgas enorm verhoogd hebben. (Zie tarieven links)

Itโ€™s been a while since I taught a course about the Border Gateway Protocol (#BGP). In the meantime, I wrote a new book about BGP, and Iโ€™ve built a completely virtual internet exchange where the course participants can practice #peering with each other. It runs on a Raspberry Pi.
