Well done. The #ACL removed ("desk rejected") over 100 accepted papers from the #ACL2026 program and proceedings that contained citations to non-existing literature:
"The inclusion of these non-existent references is a clear violation of the ACL Policy on Publication Ethics."
Some authors may have already made travel plans. Statement at: https://2026.aclweb.org/acl_statement/

Nice, the state of Information Retrieval in 2026 by Mohan Krishna. Lots of interesting references and thoughts, if you're into leaderboards and state-of-the-art performance on benchmark test collections. #InformationRetrieval

As I grow older, I more clearly see how science is never truly objective; That all scientific studies have political implications.
To my horror, I am starting to realize that some of the things I learnt and taught, such as significance testing, are rooted in vile, violent racism. Please, read Aubrey Clayton's "How Eugenics Shaped Statistics: Exposing the damned lies of three science pioneers."

Call on ABP: break ties with BlackRock: Sign the petition!
Why? Because #BlackRock keeps investing money in fossil-based industries. #ABP is one of the largest pension funds of the Netherlands. It organises pensions for academics like me. I don't want my money to support Blackrock. I don't want my pension to evaporate when Blackrock starts depreciating their investments.

My Fairphone 3 with e/OS does not even have speech to text(!) It does block trackers that are inside Android apps; allows you to use a fake location; you can hide your IP address using the tor network, and if you insist on using cloud storage it seamlessly intgrates with nextcloud. Pretty neat if you ask me

Israeli newspaper Haaretz tells 28 stories behind the staggering death toll of children in Gaza, their faces, names, and dreams that will never be realized:
Hind pleaded for help for hours. Youssef was killed while watching cartoons. Yaqeen wanted to be a YouTube star and died in a bombing. In death, Maria joined her mother and brothers, killed in an airstrike in 2021. #Genocide #GazaGenocide

Anita Naidu about Rutger Bregman: "Bregman has given elites a playbook for the next chapter of power laundering"

Israel likely murdered 377,000 people in Gaza, A report prepared by Garb Yaakov, a professor at Ben-Gurion University of the Negev in Israel, and published on Harvard Dataverse website shows that the officially reported death tolls in Gaza are way too low. Half of the 377,000 that "disappeared" are children.

Excellent reasons for not putting all research software in #Github in this post by Luisa Orozco, Daniela Gawehns and Carlos Martinez-Ortiz
1. Github excludes potential collaborators. It is inaccessible to users in countries under financial sanction by the USA. (Iran, Syria, Cuba, North Korea, etc.)
2. Everything on Github creates a single point of failure. It has the possibility of being closed down, similar to what happened to Google Code.
Instead ilnk any git repo!

Dear fedi friends,
Who knows a web service that analyzes privacy concerns in web pages? I am looking for a site that checks for trackers, advertisements, etc. In web sites. Something like what @npub1duq…razf is doing for Android applications. Suggestions and boosts are welcome.
