The perspective is cool, though.

that is part of the problem.... it is way to cool here at the moment... 😉

:drum_with_drumsticks:

Great pic 🙌

Windy here too

I think I’ve cycled that path on the way into Copenhagen when we rode our bikes there from Berlin a few years ago. 🙂

Wow, that’s quite a long ways. Was Copenhagen the final destination or did you go even further?

We followed this very popular route: http://www.bike-berlin-copenhagen.com Something possibly of interest is that there were quite a number of families with small children in cargo bikes riding the route, in case you’d like to come visit sometime. 🙂

Our longest ride so far was a combination of two https://en.wikipedia.org/wiki/EuroVelo routes to travel from Berlin to Paris, camping along the way. It was also lovely.

Hmmm very interesting :thinking_face: not sure the one I have is the best choice for long distance travel, though, since it's a 3-wheeler.

Maybe one of your other bikes plus a trailer 😄

Yeah, something like that 😊

interesting. I’ve never used https://jena.apache.org/. Perhaps take a look which parts of your code is calling jena? Or perhaps you’ve found a bug in jena? It sort of seems like this isn’t supposed to happen.

yeah…

I’ll bet you a beer that it’s happening in TDB’s MappedByteBuffers code, related to block access in the underlying DB.

Yeah… I guess it’s somehow related to this graph in particular being built on a resource-scarce server while people are attempting to access it. Gonna try to rebuild on my own machine and upload the database to the server.

This is typically caused by an OS signal (SIGBUS — bus error) being thrown while accessing a memory mapped file, which mostly happens from things like running out of disk space or having the underlying file modified beneath you. You are absolutely right to guess that it’s a resource problem on the machine.

not really used to running Jena in prod, so I guess I’ll be learning a thing or two

I’ve never used it in prod (or much at all), but I’ve implemented my own database storage systems that use the same mechanism, so… 🙂

https://www.w3.org/2001/sw/Europe/events/20031113-storage/positions/rusher.html? I think I ran into that page 1 or 2 years ago (I followed a wikipedia reference or something). Was surprised to find your name as I mostly associated it with genart back then.

Inclusively, but not exclusively! Anyway, yeah, I have a fair few “right place, right time” things like this one. I’d been building reasoners over knowledge graphs since the 80s, and ended up making the first purpose-built TripleStore for the Semantic Web. That tiny paper is cited in loads of textbooks and the Wikipedia page for the topic. 🙂

I remember stumbling across that work and thinking, "what else? wrestling crocodiles?"

He conviently keeps the location to the fountain of youth a secret, though...

Just clean living and yoga 😄

I don't buy it

The real secret is lifting heavy weights, but almost nobody listens to that advice :man-shrugging::skin-tone-2:

Nice, then I'm all set
