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](https://fd.io/)].
|
|
|
|
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 :)
