Efficient Polynomial Identity Testing Over Nonassociative Algebras
We design the first efficient polynomial identity testing algorithms over the nonassociative polynomial algebra. In particular, multiplication among the formal variables is commutative but it is not associative. This complements the strong lower bound results obtained over this algebra by Hrubeš, Yehudayoff, and Wigderson (2010) and Fijalkow, Lagarde, Ohlmann, and Serre (2021) from the identity testing perspective. Our main results are the following: (1) We construct nonassociative algebras …

From Birdwatch to Community Notes, from Twitter to X: four years of community-based content moderation
Community Notes (formerly known as Birdwatch) is the first large-scale crowdsourced content moderation initiative that was launched by X (formerly known as Twitter) in January 2021. As the Community Notes model gains momentum across other social media platforms, there is a growing need to assess its underlying dynamics and effectiveness. This Resource paper provides (a) a systematic review of the literature on Community Notes, and (b) a major curated dataset and accompanying source code to supp…

Chris Cuomo Loses Appeal Bid to Disqualify Arbitrator in CNN Proceedings
The former CNN anchor initiated the proceedings after he was fired by the network for giving advice to his brother, who was accused of sexual harassment.

Just listened to an interesting online talk (#Balloon Facility (https://www.tifr.res.in/bf/) - here are the slides about astronomical observations they do; see also https://arxiv.org/abs/2112.04877 for a 2021 review paper about this work and the mentioned papers https://www.aanda.org/articles/aa/full_html/2013/08/aa21614-13/aa21614-13.html ("Large-scale mapping of the massive star-forming region RCW38 in the [CII] and PAH emission") and https://www.aanda.org/articles/aa/full_html/2021/07/aa35739-19/aa35739-19.html ("[CII] emission properties of the massive star-forming region RCW 36 in a filamentary molecular cloud").

For the past 15 years, I've observed San Francisco leaders talk about how important climate action is - but not actually do a lot. There now a petition asking the Mayor to take meaningful action at

Mayor Lurie: Prioritize Climate Action Plan goals as you restructure city government
San Francisco approved a detailed and comprehensive Climate Action Plan in 2021 with a top-line goal of net-zero GHG emissions by 2040. Some progress towards this goal has been made since then, including general fund budget money awarded over the last few years to the SF Environment Department, for the first time ever. But we are now in danger of going backwards in our fight to mitigate climate change. Mayor Lurie and the Board of Supervisors recently approved a 2-year budget that revokes...

lifeXplore at the Lifelog Search Challenge 2021
Since its first iteration in 2018, the Lifelog Search Challenge (LSC) continues to rise in popularity as an interactive lifelog data retrieval competition, co-located at the ACM International Conference on Multimedia Retrieval (ICMR). The goal of this annual live event is to search a large corpus of lifelogging data for specifically announced memories using a purposefully developed tool within a limited amount of time. As long-standing participants, we present our improved lifeXplore - a retrie…

A study published in 2021 presented cuttlefish with a new version of the "marshmallow test",
and the results showed there's more going on in their strange little brains than we ever suspected.
Their ability to learn, anticipate future rewards, and adapt their behavior, the researchers said,
may have evolved to give cuttlefish an edge in the cutthroat eat-or-be-eaten marine world they live

Banking alliance aimed at limiting fossil fuel investments collapses
A coalition formed to align the international banking sector’s investments with global climate goals has disbanded nearly four years after it was launched. Set up in 2021, the Net-Zero Banking Alliance (NZBA) was a U.N.-sponsored initiative to shift bank financing away from fossil fuels — the biggest source of climate changing greenhouse gases — and […]

Carney has announced LNG Canada will be expanded to its full potential. It will produce as much GHG emissions as 75% of the entirety of the province of British Columbia does right now. Yes, that's right. BC produced 61 million tons of GHGs in 2021, LNG Canada will produce 46 million tons at full power.
I am glad communities and health professionals are demanding a full inventory of the health impacts of this infrastructure. I hope that will also include the directly attributed heating from this plant to the increase in likelihood for wildfires, heat waves, and all the rest with all those health impacts across BC and the globe.
This is a gigantic project. Canada is a gigantic Climate Problem.
