Transformer by hand ✍️ in Excel ~ I just released my first-ever "Full-Stack" implementation of the Transformer model. 👇Download xlsx to give it a try!

I built a Vector Database and a Sentence Transformer in Excel in front of 250+ live on Zoom.👇 Link below to download xlsx or watch recording.

📈Top cited articles from the last two years of ACM CHI (ACM CHI Conference) – the premier publication venue for HCI ("Human-Computer Interaction") research. What do you notice?

DeepSeek lecture is edited and uploaded 👉 by-hand.ai/dpseek ~ Thank you all 🙏 for attending my public lecture yesterday. In one hour, I managed to build a simplified DeepSeek model in Excel in front of a live audience of 3000+ people.

Please consider submitting to HumanAISE (colocated with FSE/ISSTA)! Looking forward to discussing your exciting and interesting work that integrates human insights into AI4SE (check website for more topics)!

🔬Research ideation is hard: After the spark of a brilliant initial idea, much work is still needed to further develop it into a well-thoughtout project by iteratively expanding and refining the initial idea and grounding it to relevant literature. How can we better support this?

📢 New Research Alert! Just posted initial details of our latest papers across #CHI2025, #IUI20205, and #HRI2025! All work led by incredibly talented graduate students. Human-Centric AI, Programming Tools, Mixed-Reality, Robotics, and more! 🔗 tovigrossman.com (1/13)

#CHI2025 Coding Partner or Intruder? We designed, tested Codellaborator, a proactive AI assistant that initiates coding help. Compared to Copilot, we found: - Faster coding, but workflow disruptions - AI presence & local context eased confusion - Felt more like collaborating

Big Congrats Karthik Mahadevan !

Are you a programming instructor? We want to hear how AI is shaping your courses! Take this quick 5-minute survey: forms.gle/tuN8jeiLw978Kt… #EdTech

Are you a professor who leads (or has led) a research lab? We’re studying how labs manage organizational memory—shared knowledge, mentoring, documentation, etc.—and would love you to participate in a 45-minute interview ($30 compensation). Please sign up forms.gle/XBCCzJ73MwZ3K7…

Are you a *senior* professor who has graduated more than 2 Ph.D. students? We’re studying how labs manage organizational memory—students' roles, mentoring, documentation, etc.—and would love you to participate in a one-hour interview ($50). Plz, sign up forms.gle/K35nEK5A2cndCP…

Glad to see this work coming out at #CHI25! Come to our session and chat with Kevin Pu 🥳

What's so amazing about this work—knowing the inside story—is that it was stuck in the resubmission process for ~2yrs. The fact that it is even more relevant now is incredible. Kevin was *so* prescient. Go attend his talk at #CHI2025, and see the future!

Should you look at the camera to fake eye contact in job interviews? Our #CHI2025 paper says you don't have to. We found no evidence that looking at the camera helps perform better in job interviews. Jelson (Jelson) will present the paper tomorrow! dl.acm.org/doi/10.1145/37…

Wrapped up #CHI2025 on a high note with two amazing students, Kevin Pu and Xiaohang Tang , presenting the results of their years-long efforts. So proud of their hard work and growth. Already looking forward to CHI next year! #ProudAdvisor

CHI2025 just wrapped! So proud of my amazing PhD student Buse Çarık for presenting her first CHI paper. Big thanks to everyone we got to meet—your ideas, insights, and hallway chats made Yokohama unforgettable. Until next time. 📍#CHI2025 #Yokohama ACM CHI Conference

CHOIR = Chat-based Helper for Organizational Intelligence Repository It answers students' questions based on your lab handbook and updates the doc by learning from your conversations. See CHOIR in action: youtu.be/gPdVIjzLKd4 CHOIR is developed by Sangwook Lee. (2/3)

Should programming students take notes/just watch/type along during live coding lectures? Danny Manesh (tinyurl.com/hkjpymxp) will present his ICER paper on Monday at 915am (EST) to showcase a new live-coding note-taking system that reduces students’ mental load while still
