I did some data analysis of my 2024 Google calendar events on the first day of Spring break: eltsai.github.io/posts/2025/ā¦
Presenting our WWW 2025 paper "Harmful Terms and Where to Find Them" at the NDSS poster session today!
Many T&Cs hide unfavorable financial termsāhidden fees, tricky refunds, forced arbitration. We use LLMs to analyze 1.8M T&C lines and build a tool that flags them in real-time.

I have some thoughts about how LLMs have transformed my life, but I can't quite articulate them. (1/9)
When I encountered unfamiliar words (English isnāt my native language), I used an LLM-based etymology tool (that I also found on my X timeline) to analyze them (deconstructor.ayush.digital/). (8/9)
this is so cool
Language Models Use Trigonometry to Do Addition
"We first discover that numbers are represented in these LLMs as a generalized helix, which is strongly causally implicated for the tasks of addition and subtraction, and is also causally relevant for integer division, multiplication, and modular arithmetic. We
then propose that LLMs compute addition by manipulating this generalized helix using the āClockā algorithm: to solve a + b, the helices for a and b are manipulated to produce the a + b answer helix which is then read out to model logits. "
Today in Xplore Engineering we showed 4-7th graders how to train ML models, and how to fool them š¤

Excited to attend #FOCI2023 and #PETS2023 in person this week! @MustbeElisa will be presenting our paper on detecting DNS manipulation using TLS certificate information on Thursday, July 13! Come find us in Section 7B!
I came across Philipp Winter's Research Power Tools. I found it very insightful and applicable (also interesting and amusing to read). I put the digest of it on telegraph:
