After nine years, I finally managed to check off watching the Harry Potter and the Cursed Child play from my bucket list today.

The end of an era. After 6 years of teaching and research, it was time to say goodbye to the VUB and @wise.vub.ac.be . It is nice to start something new, but I will definitely miss it.

Submitted my first iOS application for review (as an Android user). One second hand iPhone and a lot of cursing later... Let's see how this goes @sembeacon.org

So you want a fillet in your 3D CAD program? Sure! here is a video on how to do it. #AI

I should probably have guessed that the German trains I had to take for my vacation were gonna get cancelled. Luckily the next one is in 4 hours... Hopefully..

So... I can no longer trust asking the day and weather on my phone

This afternoon, my PhD student @maximvdw.be successfully defended his PhD thesis in public. Congratulations again Dr. Maxim Van de Wynckel!! solid.maximvdw.be/publications... @openhps.org @sembeacon.org #VUB #positioning

@maximvdw.be is going to publicly defend his PhD thesis 'Interoperable and Discoverable Indoor Positioning Systems' on June 30 at 15:00 (location: VUB LIC.0.04)... www.vub.be/en/event/phd... @wise.vub.ac.be #VUB @openhps.org #positioning

Our @openhps.org framework is now published in the Journal of Open Source Software

Welp, totally did not realise it - but I gave my last exercise session today at the VUB. It was only when a student pointed it out after asking me about my research.

Tonight I learned that the @openhps.org logo looks like the flag of Okinawa Island (Japan)

Our latest #OpenHPS update enables developers to stream processed (location) data to #Solid using Linked Data Event Streams ( #LDES ). Simply adding a sink to an OpenHPS model is all it takes to enable this in existing positioning systems. Read more in our blog post ... openhps.org/posts/2025/0...

Our two Solid papers from SoSy 2024 are now available online: ceur-ws.org/Vol-3947/sho... ceur-ws.org/Vol-3947/sho...

Always fun every year to give an exercise session that uses @openhps.org

🗞️ Deze week in Knack. Mijn onderzoek aan de Vrije Universiteit Brussel in de kijker via de rubriek 'Jong talent'. www.knack.be/nieuws/techn... Met het #SolidProject en ons OpenHPS.org raamwerk leggen we samen de basis om gebruikers controle te geven over hun locatiegegevens.

The first student presentations for the course 'Next Generation User Interfaces' were held today. Some interesting ideas were presented! Looking forward to the results at the end of the semester ;)

I am surprised that after 6 months there has not been an accident yet #Brussels #construction

Last Friday, 'Le Groupe Belge de Recherche Scientifique Sous-Marine' organised a scientific experiment for underwater positioning of objects using trilateration. The measurements went fine, but the data exchange not so much - even humans seem to need some predefined 'specifications' to communicate.

At least Google puts a disclaimer that it works even if you remove the permissions 🙃

Did you miss my presentation at #FOSDEM about discovering indoor environments? No worries, the recorded talk is now available: maximvdw.be/presentation...

"I found a couple requests sent by my phone with my precise location + 5 requests that leak my IP address, which can be turned into geolocation using reverse DNS." Yikes timsh.org/tracking-mys...

If you want to find me at #FOSDEM, just follow my WebID in the SemBeacon app

Well, as for troubleshooting of why the demo did not work: accessing the Web requires an internet connection - which I forgot to configure for the demo phone. Can happen :) #livedemo

But first a very interesting talk by @maximvdw that discusses how #semantics and one level of indirection make interoperable indoor mapping possible, called SemBeacon. Using `schema:Map` floor maps, GeoSPARQL for #fosdem #fosdem2025 Ontology at https://github.com/openhps/poso. #fosdem #fosdem2025

@maximvdw.be is currently presenting our work on discovering indoor environments and indoor positioning systems based on ‬POSO and @sembeacon.org at #FOSDEM. livestream: fosdem.org/2025/schedul... wise.vub.ac.be/topic/locati... @fosdem.bsky.social #positioningsystem #interoperability

I am giving a talk at 11:00 at #FOSDEM in the #Geospatial devroom about discovering indoor environments and indoor positioning systems. Primarily discussing the use of POSO and @sembeacon.org to help achieve this goal. #positioningsystem #locationbasedservice #interoperability

After receiving feedback from the #IoT conference and investigating additional cases, we released version 1.1 of our SemBeacon spec, introducing some non-breaking changes to the ADV flags. These flags are used to determine if a beacon's advertised URI should be accessed github.com/SemBeacon/sp...

With the release of the POSO #ontology v1.1 last month, we are now looking for new use cases that are currently not possible with the #positioning system ontology. If you have a use case that is impossible yet, feel free to create a use case issue. github.com/OpenHPS/POSO #linkeddata #geospatial

Location data of 800,000 Volkswagen cars leaked, 30M location data points from apps exposed, and 40,000 apps selling location data. This is what happened to your location data in the past month. We are surveying user perspectives on location data: s.maximvdw.be/3G0 #cybersecurity #privacy
