Edit Distance Robust Watermarks via Indexing Pseudorandom Codes
Motivated by the problem of detecting AI-generated text, we consider the problem of watermarking the output of language models with provable guarantees. We aim for watermarks which satisfy: (a) undetectability, a cryptographic notion introduced by Christ, Gunn, & Zamir (2023) which stipulates that it is computationally hard to distinguish watermarked language model outputs from the model's actual output distribution; and (b) robustness to channels which introduce a constant fraction of adversarial insertions, substitutions, and deletions to the watermarked text. Earlier schemes could only handle stochastic substitutions and deletions, and thus we are aiming for a more natural and appealing robustness guarantee that holds with respect to edit distance. Our main result is a watermarking scheme which achieves both (a) and (b) when the alphabet size for the language model is allowed to grow as a polynomial in the security parameter. To derive such a scheme, we follow an approach introduced by Christ & Gunn (2024), which proceeds via first constructing pseudorandom codes satisfying undetectability and robustness properties analogous to those above; our codes have the additional benefit of relying on weaker computational assumptions than used in previous work. Then we show that there is a generic transformation from such codes over large alphabets to watermarking schemes for arbitrary language models.
The Simplistic Moral Lessons of "Superman"
The world may be going to hell, but the writer and director James Gunn has graced it with a sunshine "Superman." The most recent installments in the franchise--Zack Snyder's diptych "Man of Steel" (2013) and "Batman v Superman: Dawn of Justice" (2016)--had a hectic, howling, near-apocalyptic sense of tragedy, but Gunn's vision is bright, chipper, and sentimental. A title card announces that Superman has endured his first defeat, and the hero (played by David Corenswet) is shown tumbling from the sky and slamming with a sickening thud onto the surface of a frozen wasteland, where he lies prostrate, spitting red blood on the snow. Fear not: no sooner does the wounded combatant put his lips together and whistle for Krypto than his faithful and frisky canine companion arrives and drags his master back to the Fortress of Solitude. There, loyal robots examine the patient and, by exposing him to sunlight, begin to heal him.

James Gunn Takes Dig At Rotten Tomatoes For Mistakenly Featuring DCEU Poster With MCU Title
Rotten Tomatoes recently shared a list of DC Extended Universe (DCEU) movies to explain the timeline. However, they mistakenly featured the Marvel Cinematic Universe (MCU) movie, "Guardians of the Galaxy" title in that list. This mistake has not gone down well with director James Gunn, who was quick to take a dig at the list. Gunn reposted Rotten Tomatoes's tweet on Wednesday, and wrote, "I'm surprised Guardians is after Birds of Prey in the DCEU timeline." The comment came after the DCEU timeline featured a poster of Gunn's recently released TV series, "Peacemaker," but the title was written "Guardians of the Galaxy."

Chris Pratt Believes 'Guardians Of The Galaxy Vol. 2' Will Be 'Greatest Movie In History'
Maybe he is just biased, but Chris Pratt already believes "Guardians of the Galaxy Vol. The actor, who plays Peter Quill, a.k.a. Star Lord, in James Gunn's upcoming film, drummed up hype for the film when he posted the IMAX poster for the upcoming film on Facebook. He said the movie has already gotten a surprisingly high rating from Rotten Tomatoes, and he suspects it will win every award there is to be won, including medals at the Olympics. One of the most exciting things about the new movie has to be the introduction of Star Lord's father, Ego (Kurt Russell). Gunn earlier revealed during an interview with Complex that he's made certain changes to the comic book character and made him into a "normal person." "Ego is a living planet who is able to manifest himself in different ways he's been alone for millions of years and he's learned how to control the molecules around him in such a way as to create avatars of themselves, such as Kurt Russell," Gunn said. "I think Ego was a very lonely character out there by himself and went off in search of love and perhaps found it in Quill's mother." Despite being another movie from Marvel, Gunn also said that he is not pressured to connect "Guardians of the Galaxy Vol.

Steve Gunn brings a wandering, cosmic spirit to guitar-based rock
In this always-on, phone-obsessed era, Steve Gunn's "Eyes On the Lines" is a rarity. Released earlier this year via respected New York indie Matador, it's an album about getting lost in the little details -- taking the time to enjoy the music of a busker, for instance -- and of learning how to roll with life's annoyances. In a Gunn song, that's simply an excuse to enjoy a wasted afternoon and grab a hotel room. At once meticulously crafted yet casual, arrangements on the nine-song album are loose-fitting. Guitar solos emerge not to lead but to detour.
