Today I got up early so that I could join NLNOG, in spirit at least. It starts at 09:00 but the content will be only half an hour later at 09:30. The NLNOG has a special place in my heart, as I've been a member of this community since the 90s and well before it was an official thing. The board are all staples and fixtures in the Dutch internet community, and I really enjoy re-connecting with the group as I started working more on open source routers like [VPP].
After the opening, Yurii Polovyi of RETN discusses wavelength division multiplexing, CWDM/DWDM and (R)OADM solutions in the industry. It's an interesting overview. Next, Leroy de Vos (from AMS-IX NOC) gives a touching story about his own career from humble beginnings to the NOC of one of the largest internet exchanges on the planet.
In the coffee break, I start up the flight simulator and decide to fly my Cessna 172S skyhawk from Belp to Annecy in France. However, I'll plan a route over the alps this time, so I get to fly at 11'000ft. In the process, I learn about the fuel mixture settings (lean during taxy, rich during takeoff <3'000ft, lean over 3'000ft). It's really amazing how well this simulator is programmed. As I touch down in Annecy with a straight in final approach, the NLNOG conference has already continued.
On stage are Ondrej (RIPE), Arjan (Event Infra), and my buddy Andrew (Cisco) talking about how to make events networking uneventful. Each brings their own perspective, from outdoors venues (with Datenklo's) to huge indoors venues and a single room with 6000+ people in it. I also learned that the equipment sits in some storage room somewhere and weighs seven metric tonnes. Heh.
Teun Vink takes us to a serious topic - specifically for those of us who have aging family members - and discusses our digital legacy. It's a presentation of pictures and the story it tells really spoke to me. Teun leads us in to lunch, and I as well have a sandwich and a cup of tea. I also fly my plane from Annecy to Dijon and I touch down on runway 02 and park the plane.
After lunch, Rudi van Drunen shares a view into critical Dutch infrastructure with Networks at Air Traffic Control the Netherlands. On the heals of that, Bert Hubert brings 'part four of the triology' of social life lessons with Life long learning: dealing with change. We all drink some coffee, and I take a cup also, as I type away some of my e-mail backlog.
After the break, Robin Gilijamse has a story with A Case Against Automation - I feel a little bit uncomfortable with the speaker venturing into aerospace investigations and drawing some conclusions that I would not have necessarily drawn. After Robin, Ties de Kock of RIPE NCC shares details of the key management of RPKI HSM. What is possibly my favorite story of the day is from Frank van Vliet, Debugging the impossible: the bit-flipping story. After his talk, one of the folks who lined up at the microphone was a senios engineer from KPN itself, saying thanks for the elaborate debugging :)
I do not participate in the kahoot quiz, as doing so remotely will give me a transmission delay and I'll miss all of the questions. But, I do monitor it form afar, and I appreciate the quirky questions Peter and Pieter put in. What happens next in Amsterdam, I will have to miss: the drinks, food, hanging out and exchanging stories will all be for a next time.
Considering I will be traveling to Barcelona tomorrow, and I have a few minutes to spare, I drive over to the Interxion datacenter and do some pending maintenance for IP-Max: the current 100G link from Interxion to Frankfurt is suffering from what seems to be electrical issues in the CFP cage. So I move myself to the floor at 23:30 when traffic is calmer, drain the link, and move the connection to both another optic and as well another port. I am successful: the occasional frame corruption is entirely gone. So that's at lease one productive thing I did today :)
