PID to Portal project update — April 2026
A few months ago, we published a post about experimenting with a next-gen ORI data infrastructure — an open, serverless data lake built on DuckDB, Parquet, and SURF Object Store, designed to power national Open Research Information monitoring. At the time, we were testing whether the architecture was even viable. Today, we have an update: the lake has data in it, and you can now talk to it in plain English.
Hoe studeren studenten nu eigenlijk voor hun tentamens? Dat vragen een hoop docenten, ondersteuners en ook medestudenten zich af. Tijd om het studenten te vragen. Ik heb studenten van de Vrije Universiteit Amsterdam hierover geïnterviewd in panelgesprekken. Studenten uit alle jaarlagen en uit verschillende disciplines waren betrokken. Wat antwoordden ze en hoe kunnen we die antwoorden gebruiken om het leerproces te verbeteren? Dat lees je in dit artikel.
At the SURF Open Innovation Lab we like to keep track of technical developments in XR technology, and one of the ways of doing that is by evaluating the latest hardware (both by ourselves, as well as asking feedback from the SURF community).
On 26 October the first set of Quest Pro headsets from Meta was delivered world-wide, for those who ordered early, which included SURF as well. Here, we'll summarize some initial impressions, after trying out the Quest Pro for a couple of hours. The main reference points are other XR headsets with similar features, i.e. the Microsoft HoloLens 2, the Varjo XR-3 and everyone's current favourite, the Meta Quest 2.
Note that we will undoubtedly tweak these conclusions after much more use, including giving demonstrations of the Quest Pro during XR on Tour and getting feedback on it, and will update the text here where needed. But first impressions are also worth something, hence this article.
Edit 27/10/22: clearified some things in the text, but no major updates
With over three million scientific publications per year, staying afloat in the ocean of scientific information is a struggle. In this article, we introduce Open Knowledge Maps (OKMaps), a visual discovery tool that improves the visibility and discoverability of scientific knowledge. We further discuss the system-of-systems approach of OKMaps, which allows for easy integration into existing scholarly infrastructure, and how this links to ongoing efforts in the Netherlands to create a national knowledge base for open research information.

“We denken dat studenten met een rugzak vol leerstrategieën van de middelbare school komen, maar dat is niet zo. Uit onderzoek weten we dat die rugzak behoorlijk leeg is”, aldus Patrick Sins, lector Leren aan de Hogeschool Rotterdam. Veel studenten lopen vast in het vervolgonderwijs, omdat ze niet goed kunnen plannen en moeite hebben met leren. Docenten hebben een belangrijke rol in het aanleren van zelfregulerend leren. Op de Kennisparade van de Hogeschool van Amsterdam gaven Patrick Sins en Andries Vroegrijk hierover een wervelende masterclass.
Hardware architecture improvements had relied on Moore's law and Dennard scaling for some decades. According to Moore's prediction, the number of transistors on a chip doubles almost every 18 months. According to Dennard scaling, as transistors become smaller, their power density stays constant. These allowed manufacturers to raise clock frequencies without significantly increasing overall circuit power consumption. Nowadays, Moore’s law is not happening as predicted, and Dennard scaling law is broken down. To address this, (homogeneous) multi-processors were invented, and opened a new era for parallel processing to gain better performance with a reasonable increase in power consumption. However, homogeneous multi-processors cannot keep up with high-demand application requirements such as low power, energy efficiency, and high performance.
