+I wrote a lot today, but it was not this journal entry. In the morning, I completed the acceptance
+loadtests for the upcoming `sFlow` plugin in VPP. You can find this code on
+[[GitHub](https://github.com/sflow/vpp-sflow)], and I took a first pass review over the code so far,
+ended up formatting it into a [[Gerrit](https://gerrit.fd.io/r/c/vpp/+/41680)] on the
+[[FD.io](https://fd.io/)] code tracker.
+
+The main contribution of the day was writing this
+[[article](https://ipng.ch/s/articles/2024/10/06/vpp-with-sflow-part-2/)]. In the afternoon, I
+tidied up the backing data for it, and in the evening I spent some time with Neil closing off a few
+loose ends, and grooming the [[issues](https://github.com/sflow/vpp-sflow/issues)].
+
+It's striking to me what a great difference in attention and time spent writing an IPng article
+versus writing a journal entry. The latter is pretty much just autopilot, the dutch would say "van
+je af schrijven", perhaps a close analogy in English is "free word association". Just whatever comes
+to mind. I often use visual cues from the picture gallery, as that reminds me of what I did. I
+figure: if it's important enough to snap a picture of, it's probably important enough to write a
+sentence of two in my journal. 
+
+With technical articles, it's very different for me. They need to follow a structure, setting the
+context, providing necessary back references and most importantly, they need to be _correct_. Doing
+math is hard, and doing correct math even harder still! Taking today's article as an example, I
+rewrote it twice. I had in mind to create a version 2 .. version 5 style iterative storyline,
+showing what we concluded and what we improved on. But, I lacked the literal setup, what am I
+testing, what is the LAB setup, T-Rex configs, and so on. If people were to want to reproduce my
+work, they will find the article I landed on better than the one I started with. 
+
+But the cost of this approach is, of course, time. All in all, this article took about eleven hours
+to write, and I ended up committing it after dinner, only to make a few edits for clarity and
+readability (and typos) in the late evening. I'm planning on a third article, that discusses what
+happens _outside_ of the VPP dataplane, in other words, how this thing integrates with existing
+tools and products, perhaps using [[sflow-rt](https://sflow-rt.com/)] or
+[[Akvorado](https://akvorado.net/)] as end-to-end examples. That one is going to take a while to
+develop and report on, as well, but I think it's worth it, for the community.
+
+If all I did is write one web page in the entire day, no pictures were taken :) To leave my gallery
+not entirely empty, I've added a screenshot of one of the T-Rex loadtest runs that made it into the
+articles.  Tomorrow, we ship off to Italy and I hope the traffic deities will bless our travel, as
+the Fall vacation has started and who knows how many people will try to cram themselves through the
+Gottard tunnel?

+Today we drive from Zurich to Piacenza, Italy. Marina has her Monday drawing course in Oerlikon, and
+I promise to pick her up at the Oerlikon station at noon. In the morning, I pack up the car and grab
+our belongings. I have to say, NOGs are a very social phenomenon. How I got to Piacenza is perhaps a
+typical route: on FOSDEM 2024 I presented on VPP and MPLS. In the audience there was one Kostas from
+Athens, who organizes the GRNOG series of conferences. He asked if I would be interested to come
+present my work there. I was more than happy to join GRNOG'16 and it would be a good chance for me
+to re-record the talk, as at FOSDEM unfortunately the microphone battery died shortly after I
+started presenting, which made the recording unusable.
+
+So off to Greece we went, and it was a truly wonderful time. At GRNOG, I met one Alessandro from
+Italy. As we were having dinner with the folks from LANCOM (a datacenter operator and telco from
+Thessaloniki), Marina sat at the _Italian_ side with Livio and Alessandro, and when I came over to
+chat, they both said it'd be fun to have me in the upcoming ITNOG _On The Road_ edition, which would
+be in the home town of Alessandro and his company [[Naquadria](https://naquadria.it)]. Well, since
+Zurich - Piacenza is only 4.5hrs or so by car, I thought: why not?
+
+Fast forward to today, I picked up Marina in Oerlikon after a brief runaround due to roadworks at
+the train station, and we made our way down South. I consider myself truly blessed to be able to
+humblebrag that just two weeks ago, I was all the way up North in Oslo, and now I'm finding myself
+driving all the way South to Piacenza.
+
+The drive down is leisurely and calm. Somewhere along the line I drive past Luzern, where IP-Max has
+a new point of presence at the Stollen datacenter; and then I drive past Altdorf, where IP-Max used
+to have a really cool Point of Presence at Deltalis DK2 in a former military bunker (sadly, Deltalis
+went out of business so we all moved out); and then I drive past Manno, where IP-Max has a point of
+presence at the Bancadati datacenter. It's so cool to be always only a few kilometers away from an
+AS25091 PoP! Maybe we'll pull a wire over the Alps at some point and go to Italy as well.
+
+Lucky us - the Gottard tunnel is completely free of traffic. This is a looooong tunnel! I put the
+cruise control to 80km/h (50mph) and .. wait. It takes a good fifteen minutes to drive through this
+tunnel, which is truly a magificent work of civil engineering. I think my appreciation of the
+engineering quality definitely goes up if there are no traffic jams :)
+
+We make our way to Milan, drive past it on the motor way to Bologna and about one third of the way,
+we see the offramp for Piacenza, which is our $dest for the first half of the week. We make our way
+to the hotel, Marina is glad that I'm driving - you must know: compared to the german and swiss
+driving style, italian drivers are a fair bit more _artisanale_ and things like blinkers and full
+lines are all optional, and actually in several places there simply _are no_ road markings at all.
+
+But, when in Italy, drive like an Italian. And I am happy to oblige, to great amusement of my
+copilot. Piacenza is a nice town, and (luckily for us) parking in the city center is pretty easy. We
+take dinner in a small restaurant called Antonietta. We enjoy some starters with (italian) tapas,
+and then both go for fish: Marina takes spaghetti Vongole (English: clams), and I take a Branzino
+filet (Ebglish: seabass).
+
+After dinner we walked back to the car, and then the hotel, where we turn in for the night.
