+A few months ago, on Mastodon one Eduardo Collado approached me and he was asking about the FrysIX
+pins that I had made. If I could maybe send a couple to him, he'd gladgly distribute them at an
+upcoming ESNOG event. Upcoming event you say? How's about I come and bring them!? So I mailed the
+program committee and suggested to bring a presentation on VPP's ability to run Babel and OSPFv3
+without the need for IPv4 or IPv6 transit networks. They accepted, and here I am :)
+
+Yesterday, I lined up two opportunities to share my ongoing work on sFlow in VPP: one at FOSDEM'25,
+for which Luca Deri invited me to submit a _call for papers_; and another one about network
+telemetry and observability which Luca is organizing in Zurich. And so, it is proven once again,
+that NOGs are self-perpetuating. There's always somebody intersted in hearning nerdy stories and I'm
+always interested in telling them!
+
+This morning, a bunch of the participants went to visit the
+[[Marenostrum](https://en.wikipedia.org/wiki/MareNostrum)] supercomputer at the _BSC_ (Barcelona
+Supercomputer Center). It is the most powerful supercomputer in Spain, one of thirteen
+supercomputers in the Spanish Supercomputing Network and one of the seven supercomputers of the
+European infrastructure PRACE (Partnership for Advanced Computing in Europe). It has ~166K CPU,
+390TB of memory and 14PB of storage and is rated to 1.3MWatt of power. The coolest thing ever: it's
+built into a former chapel named _Torre Girona_, at the Polytechnic University of Catalonia, where
+our event is being hosted.
+
+At 10:30 the program kicks off with Ismael Castell's thoughtful presentation about Discovering
+databrokers - Bringing to light hidden companies. This presentation resonated with me, as there's so
+much data gathering and inappropriate use of my (and our) personal data on the Internet. This is
+also why I've taken to _selfhosting_ (Mastodon, Peertube, NextCloud, Immich, Plausible, Roundcube,
+and several more).
+
+After a coffee break, Gerhard Stein of Flexoptix brings us some theory and practice about Coherent
+optical transceivers – current capabilities and future capabilities. Then, Jovana Palibrik of Kentik
+talks about the adoption of RPKI ROV - in particular a huge step-function jump after last year
+Orange misplaced its password and found its prefixes rerouted and hijacked. Manuel Mendez shared an
+industry update from Arista with a gazillion different flavors of 400GE optics.
+
+Then we had lunch - very similar to the one yesterday, and I had a chat with the Flexoptix folks. We
+talked about _Return to Office_, my sabbatical (and Andrea's too!); and the state of optical
+engineering. I personally would never have thought in the 90s when I studied this stuff, that it
+would become such a huge industry!
+
+After lunch, I was invited on stage to bring my presentation entitled VPP: A 100Gbps/100Mpps+
+BGP/OSPF router with a single IPv4 address. It was fun to present here - in English and at a
+reasonably slow pace - and answer a few questions at the end. It was
+[[recorded](https://video.ipng.ch/w/i4ibtvEkUmEE39mkCNeDzQ)] and the slides are
+[[online](https://go.ipng.ch/esnog32)] as well. I also lay out a set of IPng ntag-pins which find
+new homes with the participants of ESNOG'32 at the University of Technology.
+
+After my talk, Maria Isabel Gandia of CATNIX and Amadeo Beck-Pecoz of ESPANIX give some tips and
+tricks on how to peer _correctly_ in a talk entitled _Como sacar el máximo provecho de los puertos
+de peering en nodos neutros_ (English: How to make the most of peering ports in neutral nodes),
+after which there's one more social-cultural activity: a kahoot!
+
+The kahoot is a quiz with fifteen questions about technology and cultural references from the
+spanish internet industry and its pioneers. I participate in the kahoot and, despite my Spanish
+sucking (and delays due to having to translate ES->EN and then my answer back EN->ES), I manage to
+make the podium together with a player called _Edu_ (_Eduardo Taboada_ who was gracious to give me
+his book on Proxmox!) and a player called _IPv6_. I am over the moon that I managed to win here! I
+take the time to thank the ESNOG organizers, as they did a fantastic job with the logistics and the
+varied program. I really enjoyed myself!
+
+Then just like that, ESNOG'32 is over. It's 17:00 or so and I make my way back to the hotel, where
+Marina is already lounging and ready for an ap&eacute;ro. First, we take a little walk through the
+park and I call my Dad, who is celebrating his birthday today. My parents are doing good, they just
+got their flu and corona shots (good for them!) and they ask me about my COVID episode last week. We
+have a good conversation and say our goodbyes - they will be visiting us in Switzerland in December.
+
+At 20:00 we make our way to the city for dinner. It's a bit of a puzzle to find a place that has
+good tapas, is not too far away, and is affordable. We find a place, honesty not that great though,
+and we have our food and a bottle of _Arienzo_ wine from the house of Marques de Riscal. On the way
+back we see a local sight: _Zurich_, the insurance company, as well has an office in the Diagonal
+area of Barcelona.
+
+Back at the hotel it's 22:00 and we're both a bit tired. Marina has done a tonne of walking and
+museum-visiting today, and I spent the day up and about at ESNOG. Interestingly, my Apple watch
+informs me that I have closed all three rings (12h of standing, 30min of exercize, 950kCal of
+activity). I would not have thought that!
