Under the title Data in Motion this track focuses on the deployment of data in research and the versatility of the domain that concentrates on this way of doing science. A panel, presentations and small pitches, illustrated by video or demo's, will sketch the fruits of escience and data science, and thus demonstrate the need for an RDA in support of research. Also the formation of a European Platform for e-science and data research centers will be highlighted during this session.

Video 1h 20 min. Presented by Patrick Aerts and Paul Groth.

Fun little map-based game.

How well do you know your area? Test your knowledge by locating streets on a map.

This looks quite exciting. I hope to get the time to test it.

There's of course Hypothes.is, which is an open standard, but this being built on Matrix makes it all new and shiny :-)

EU:s medlemsländer producerade 13.5 miljoner cyklar (med eller utan elassistans) under 2021, en ökning med 11% jämfört med 2020.

De största EU-producenterna var Portugal (2.9m), Rumänien (2.5m) och Italien (1.9m).
Sverige, Danmark och Finland producerade jämförelsevis få cyklar (ca hundra tusen sammantaget, varav majoriteten i Sverige).

Under 2021 exporterade EU:s medlemsländer 1.5 miljoner icke-elektriska cyklar (en ökning med 16% jämfört med 2020) plus drygt 300 tusen elektriska cyklar (ökning med 15%).
Importen uppgick till drygt 5.7 miljoner cyklar plus ca 1.1 miljoner elektriska cyklar (ökning med 17% och 37%, respektive).

De största importländerna utanför EU för icke-elektriska cyklar var Kambodja (27%), Taiwan (26%), Kina (10%), Bangladesh (8%) och Turkiet (5%).
De största importländerna för elektriska cyklar var Taiwan (57%), Schweiz (13%), Vietnam (11%), Kina (7%) och Turkiet (6%).

During the last two decades, China has made two-thirds of the world’s bicycles (60-70 million of 110 million annually). Most of the rest come from other Asian countries. Europe is back to producing ten million bikes annually, but the US only manufactures 60,000 bicycles per year.

There's a forest of sites out there with the sole purpose of allowing you to test your microphone.
This is the only decent one, as far as I know.

By that I mean it does what it says, runs no ads, and handles your recording strictly client-side.

Recently installed a new webcam by my office computer. Not long after, a thought materialised: should it not be possible to view the video feed over a remote SSH tunnel?

Indeed, here's one way to do it (I have not bothered connecting to the camera's builtin microphone, but that should be possible):

It's time to give up Github. This is my attempt to decrease my use of their "starred repo" functionality, which only helps Microsoft build a more valuable social graph.

I usually use the "star" function in one of two ways: either as a reminder to myself to check back on the project later, or as a way to promote the project (assuming Github will somehow increase the visibility of starred projects).

I reckon both of these abilities can be reproduced by hosting the list myself. Granted, the promotional value for the project is much smaller this way, but in any case the method used by Github to promote starred repos is based on some opaque and unknowable algorithm, and in all likelihood my "stars" were not making much of a difference apart from boosting the egos of some small-project owners (I'm one of them, so I know the feeling). But that's just another way that Github tries to trap us, by gamifying parts of the experience.
In any case, better federation across Gitea instances might help to establish a better way to "star" projects.

I intend to organise this list in the future, but for now, in no particular order:
