The \displaceHeads command from LilyPond snippet 861 doesn’t work correctly with notes that have beams – it removes the beam, probably due to a LilyPond bug (see here for details). This version can be used instead – it’s not as correct (the width of the beam is hard-coded), but it seems to work. (Only use it if you’re actually affected by this problem, of course, otherwise stick with the original!)

SPARQL wishlist

WORK IN PROGRESS

(But perhaps I’ll eventually submit this to the public-sparql-dev W3C mailing list…)

ordering in aggregate functions

This ends up being essentially the same proposal, but with two different motivations, so please bear with me for a moment :)

I use these files to keep my package manager metadata up to date. pacman-update automatically downloads package updates so that I don’t have to wait for the download when I actually go to upgrade the system, pacman-mirrorlist-update makes sure that the mirror list is not too outdated, and the tmpfiles.d configuration makes sure that all the updates downloaded by pacman-update (which may include many intermediate versions if I don’t upgrade for a while) don’t stay around forever.

To set up these files, copy the .service and .timer files into /etc/systemd/system/, and the pacman.conf file into /etc/tmpfiles.d/.

WDQS Workshops

Basic structure of one of my Wikidata Query Service workshops, or rather, idealized version of it that I hope to get close to :)

• before the workshop: zoom in on all domains you’re likely to visit, at least www.wikidata.org and query.wikidata.org, until text is readable from the back of the audience (I usually go for ~150%).
