IDF.social is your home if you know:

\[
\textit{idf} = - \log \frac{n_t}{N}
\]

and... everyone else!

Dear all,

For now, I will keep the site closed for registrations; but everyone can independently invite people to join using the following link to generate an invite:

https://idf.social/invites

If you know someone who wants to join this instance, then please do give them an invite!

Consider the instance open for those who know anyone on IDF.social.

"Sense of community" and an initial seed of some 40 IR researchers should be enough to keep those spammers out of here and still grow the club!

Useful contribution by SIGCHI on the road to open access:

"All of the organisations that I’ll be discussing (ACM, arXiv, IEEE, and USENIX) generate an annual revenue that covers operating costs and a surplus that is reinvested in the community and/or held as assets. These assets are crucial to secure on-going financial commitments and underwrite events. Building up these assets is necessary to underwrite increased financial liabilities as these organisations grow."

And neither is Apple."

Nieuwjaarsartikel: Onze economie vraagt om meer Europese ambitie

Maarten Camps

- Nieuwe technologieën en geopolitieke ontwikkelingen ­vragen om meer Europese coördinatie en een assertieve overheid.
- Meer Europese coördinatie van het innovatiebeleid en bij het reguleren van platforms kan voor meer groei zorgen.
- Belastingcoördinatie is nodig om de Nederlandse winsten van internationaal opererende bedrijven effectief te belasten.
