Frustrating. Seems to happen every year when any big grant deadline approaches. It impacts not just those working at the last minute on those grants, but everyone working on any application. Any planned solutions @sshrc-crsh.canada.ca?

Yeah, no thanks @lawandsociety.bsky.social

I mean, I love SF

But even if I was willing to spend $ in the US right now, travel to the US is not safe for anyone publicly critical of Trump -- which includes all law & society scholars who I would want to engage with

Sounds like a great course

But the US has always been like this: rights for some, and not others. All that changes is the target

Think Japanese internment under FDR

Or the lavender/red scares a few years later

Or Chile, Guatemala, Nicaragua

Or slavery, segregation, etc, etc

Edge case when parsing case SCC judgments:

In 8 SCR 474, Justice Strong (later Chief Justice Strong) wrote a judgment, "mislaid" it, and told the reporter just to report the case without the judgment:

Screenshot of a CanLII case with footnote 31 highlighted and a hand-drawn smiling face with two exclamation points. The footnote reads: "The learned judge, having mislaid his judgment, directed the reporter to report the case without it."

Interesting.

I like @caryscraig.bsky.social's take on this: papers.ssrn.com/sol3/papers....

I have lots of concerns about AI, but I don't think copyright law is the way to address those concerns -- and I think academics should publish fully open access anyway

Judges who say witnesses are "not credible" mean: I think they're lying

Saying that to a person who has reported experiencing sexual violence is deeply problematic

There are other ways to find that the Crown has not met the burden of proof required to put someone in jail

I put together this AI agent guest presentation for the Standing Committee on Teaching & Learning at @osgoodenews.bsky.social

Interesting to watch with a critical eye. How deep does the analysis go? What's missing? What biases are apparent?

The amount of time I spend trying to figure out how to handle null values (NaN, NaT, <NA>, Null, None) across pandas, parquet, mongo, and JSON (especially re: dates) is really absurd. Surely we could standardize all this...

The white supremacist idiocy on display at the White House yesterday was even more overt than usual. Why so many in the US simply accept this is beyond me

Meanwhile, Canada contemplating new defense partnerships with a rogue state that threatens to annex us is equally perplexing

Thanks @techpolicypress.bsky.social for the opportunity to reflect on social media surveillance and migration under the Trump Administration, referencing great work by @nanjala.bsky.social and @danmcquillan.bsky.social, and reporting by @aclu.org and @404media.co, among others

Widespread surveillance leads to abuses of power, discrimination, and the stifling of freedom of expression, says Petra Molnar. Historically marginalized communities will bear the disproportionate brunt of this type of social media surveillance, she writes.

Now, on to grading and a large backlog of email -- sorry for anyone waiting for a response!

Was working today with a locally hosted reasoning language model to see how it performs in categorizing refugee law cases involving sexual orientation

At one point the model (a distilled version of qwq 32) got stuck in a bisexual angst loop as it was "thinking"...
Image of this text [excerpted due to character limits]
<think>
Okay, let's tackle this question. The user wants me to categorize the refugee case based on the principal claimant's allegations regarding persecution due to sexual orientation or gender identity. [...]
Looking at the document provided, the case is about a claimant who claimed to be in a same-sex relationship and identified as a lesbian or bisexual. [...]
Now, looking at the categories: The options are 1 through 7. The claimant is a woman alleging persecution as a lesbian or bisexual. So, category 2 is "Lesbian woman" and 4 is "Bisexual/pansexual woman." Since she claimed both lesbian and bisexual identities, but the primary category here would be the one that covers both. However, the options are separate. Wait, the question says to pick the category that best describes the group she alleges. Since she's a woman claiming to be either lesbian or bisexual, the possible options are 2 or 4. The question is whether the primary claim is under lesbian (2) or bisexual (4). The document states the claimant alleged being a lesbian or bisexual. The categories are separate, so perhaps the answer includes both, but since we have to choose one, maybe the best fit is 2 and 4? Wait, but the options are mutually exclusive. Let me check again.
The claimant is a woman alleging she's a lesbian or bisexual. Since the categories are separate, but the question asks for the principal claimant's allegations. The claimant's primary assertion would fall under either 2 or 4. However, the question says "the principal claimant's allegations" so if she claimed both, but the categories are separate, perhaps the answer is [HIT MAX TOKENS, WITHOUT GETTING TO AN ANSWER]
