@nprofile1q... So.... my dad in his twenties used to work there in the bakery, thus I know for a fact they are the real deal :)
Also, I grew up in Gouda, but have not been there for the last several years.

At the trainstation, you can easily walk down town to the main market place where the town hall is, the stroopwafels are on one side, big church on the opposite side; it is all tiny and close by, all walkable. Emjoy :)

It looks like I'm going to have some downtime in The Netherlands in late September / early October due to airline pricing (staying an extra two days after the event I'm attending saves $1200 on airfar...

@nprofile1q... not living in .nl for years anymore, thus not close there; and hopping down here would take you too long, but:

When in Gouda go get _fresh & warm_ stroopwafels from the real original place: https://bergsbakery.nl and go pickup a Vlaai at https://www.multivlaai.nl/multivlaai-gouda for instance a https://www.multivlaai.nl/abrikozenvlaai (oh enter something random like '2804KK' to bypass their silly zipcode question). and yes they sell them per piece and can ask 'fill me a box with a piece of everything' ;) many things to chose from https://www.multivlaai.nl/vlaaien but depends on what they have made that day.
My prefered: apricot (abrikozen), appelkruimel (applecrumble), kersen (cherry).

Strolling around downtown can be nice (though not been in a few years), with the castle-alike town hall, you might be lucky to catch the cheese market. If you like architecture / stained glass then https://en.wikipedia.org/wiki/Sint_Janskerk has huge stained glass windows.
There is https://www.museumgouda.nl though have never been there myself as it is from the last several years.

In The Hague, decent down town to walk through, many different museums, the governmental area can be interesting to walk through (quite accessible); of course there is 'the beach' aka Scheveningen (try prononouncing that properly) where you can find: https://hetpannekoekenhuisjescheveningen.nl/poffertjes-scheveningen/ yes, poffertjes, something you need to try.

Next to all this is https://en.wikipedia.org/wiki/Delft which might be interesting from a downtown area with the waterways there and a historical perspective ("Delfts Blauw" comes from there amongst others); also where https://www.tudelft.nl is located.

For Rotterdam itself you will very likely enjoy: https://maritiemmuseum.nl/en

But I would go to Amsterdam, just in case you have not seen it yet: https://www.rijksmuseum.nl/en/stories/themes/the-night-watch sitting in front of it for a few minutes to be able to see the details is definitely worthy.

Another thing to look there is https://techinc.nl as one of the hackerspaces. Or ask on NLNOG IRC (https://nlnog.net/get-involved/), bet you can arrange a tour of the various datacenters with somebody if you ask ;)

Most important thing: just walk everywhere, downtown areas, typically where trains stop etc, tend to be older buildings (well, not Rotterdam that got bombed to nothing in WW2) with lots of activity and things to see and do and alive with people, many bars and pubs and parks etc. Hence, like most of Europe, having good boots and going around can be great.

@nprofile1q... thanks; exactly that a *indicator* of what one can expect with a certain combo of hardware; I think that can be very useful for people, inc me, to know what to expect as setting expectations is IMHO always a good thing; of course the caveat being that a complex setup will need more resources; thus maybe will have to score a fat box at one point, would be a good excuse ;)

@nprofile1q... do you have as a doc a table of performance expectations?

eg "a xeon X can do P" or "if you want to look at N channels of Y bandwidth you need TB3/4 with a 4ghz cpu and memory M"

or maybe better asked, guidelines of certain machine types that would make one happy; possibly just "apple m1 MacBook pro = good for N" "5090 with CPU C == good upto Z"?

this as thunderscopes are very likely to start appearing later in the year, thus might need to think about getting a proper host for it

So I'm wondering if long term it might make sense to move the VM server from a 2U to a 4U form factor. I'd need to move the storage cluster and core router each down 2U into a currently vacant spot ...
Jeroen Massar profile picture
@nprofile1q... if you have the rackspace I would always go for a 4U or bigger case: bigger, more silent fans and way more space for cards and disks; stuffing too many things in 1U like I do is not good for airflow and limits the above. But my argument for 1U pizza boxes is that it the colod ones break I can just bring one of the backups over... but yeah, one point maybe I need to get a big fat 4U too, but not with current storage and mem pricing ;)
