Tim Tregubov reposted thisTim Tregubov reposted thisThe best undergrad CS program rankings are overrated. Top schools dominate interview rates. Stanford, MIT, Berkeley, Carnegie Mellon. They’re great status signals which is why hiring teams prioritize those resumes. But when you look at who actually gets all the way to an offer, it’s a completely different story. We analyzed Paraform internal data on distinct candidates from U.S. undergraduate schools who interviewed for engineering roles, then ranked the top 15 schools by interview-to-offer rate. The schools in our top 15 convert at 9.9%, nearly 60% higher than U.S. News' top 15 at 6.2%. Only one school appears on both lists: Princeton University. Here are some other standouts: - Dartmouth College university runs the DALI Lab. DALI undergrads spend their degree building products for external partners. Five made Y Combinator batches in the last 2 years. -Tufts University CS engineering students take 8 mandatory humanities courses and can spend a full semester in a working engineering role through the co-op program. - California Polytechnic State University-San Luis Obispo's motto is "Learn by Doing," and they mean it. With 80+ engineering labs, learning is hands-on from day one. ~90% of grads land jobs within a year including at top companies like Apple, Tesla, Google, and Amazon. The schools topping our list all lean heavily on applied training. Students build things before they graduate, work in real engineering roles, and take coursework outside of pure CS. That shows up when they're sitting across from a hiring manager. If a recruiting team is screening for the same 15 “top schools,” they’re probably overlooking the candidates they’d actually want to hire.

Tim Tregubov shared thisAI and Mary Poppins: this morning my kids were listening to "a spoonful of sugar". that is the scene where Mary Poppins makes tidying up the nursery fun with a little bit of magic. the kids are a bit distracted by the magic, don’t quite know how to control it. the magic runs a bit rampant at the end and Mary Poppins has to step in and guide it. BUT! the room gets tidy, and it was a heck of a lot more fun than doing it by hand. THAT is working with AI right now — a spoonful of sugar. it can get away from you and you do need to be actively engaged, learning and collaborating together with your agents, AND working with my AI agents is making it all fun again! haha, are you Mary Poppins, the kids, or the dad who doesn’t believe in magic? (btw: this movie as a dad is real hard hitting)

Tim Tregubov shared thisI was sharing a prompt I had given claude with a friend co-worker and he said, “you don’t even talk to me like that!” The prompt was “[details] i'd like you to be super thorough. go through feature by feature flow by flow. i will be afk, so just go for it. there will be somewhat complicated code to […], i believe in you. keep going without stoping or asking me for anything as i'll be away. may the force be with you. you got this.” and anecdotally it helps, the agent takes more steps and is less likely to stop to claim it can’t solve it or needing confirmation etc. more likely to “care”. we all need some extrinsic validation sometimes. LLMs are our langauage so they encode a lot of human baggage, including confidence, pride, etc. https://lnkd.in/eSxq3XHr

Tim Tregubov reposted thisTim Tregubov reposted thisEver find a project that lives rent-free in your mind? For engineers Lauren Kidman ’25 and Ozgur Tuna Ozturk ’25, that project is "SmartMic." Now in its ninth term at the DALI Lab, SmartMic occupies their thoughts—even in those quiet moments when inspiration tends to strike unexpectedly. “Sometimes, even when I'm sleeping, ideas hit me out of nowhere. I’ll start thinking about how to fix issues with the electrical design,” says Tuna, a Mechanical and Electrical Engineering student. Pixcell's SmartScope, or "SmartMic," originated as a vision by Dr. Aravindhan Sriharan from the Geisel School of Medicine at Dartmouth. It combines the familiar, tactile experience of a traditional microscope with the cutting-edge capabilities of machine learning, allowing pathologists to examine digital tissue images with the manual control they’re used to. Designed to bridge the gap between traditional microscopy and ML applications, SmartMic preserves the physical knobs and buttons pathologists know and trust, all while enhancing diagnostic speed and accuracy. This innovation has the potential to advance telepathology and remote healthcare, creating new possibilities for rapid, accurate diagnostics. Yet SmartMic is more than just an impressive engineering feat; it's a unique opportunity for students to gain real-world engineering experience. Lauren, a Computer Engineering and CAD Design student, explains, “If SmartMic has proven anything, it’s that this kind of environment is not just possible for engineers; it can be transformative.” Collaborating on this project, which rivals the complexity of many senior capstones, has offered students invaluable skills in mechanical design, digital imaging, and ML integration—skills often reserved for advanced professional settings. This experience at DALI has sparked the idea for a fourth program track specifically for engineering students, who, like Lauren and Tuna, seek opportunities to bridge the gap between theory and hands-on application. Tuna notes how such practical exposure could extend beyond a single project, sharing, “In our systems class, we have a lab where we test an air car to determine its drag coefficient. If we could carry that experience over into control theory, integrating feedback mechanisms, it would make our learning more cohesive and applicable to real-world engineering.” Partnering with the Makerspace, DALI provides students access to state-of-the-art resources like 3D printing, laser cutting, and electronics prototyping. This interdisciplinary space encourages students to experiment and innovate, equipping tomorrow’s engineers with the hands-on experience and practical skills needed to make a positive impact. With the new engineering track, DALI aims to cultivate an environment that challenges students while giving them the tools to succeed. As the SmartMic team shows, the path from a concept to an impactful real-world solution is just a few steps away—and at DALI, it’s a journey worth taking.

Tim Tregubov reposted thisTim Tregubov reposted thisWhen we were building the ByDesign MVP with Dartmouth College’s DALI Lab, I initially didn't want a Dashboard feature. But one of their talented student designers, Anca Bălăceanu, convinced me to give it a shot. Today, the Dashboard is one of our most popular features, with users spending an average of 50% of their time there. Sometimes, the best ideas come from being open to different perspectives—thanks, Anca, for your vision!

Tim Tregubov liked thisTim Tregubov liked thisI’m excited to share that I’ve moved to New York and started a new role as Chief Operating Officer at Columbia University’s Climate School. Leaving Dartmouth College/the Thayer School of Engineering after 16 years was not an easy decision. I’ve been incredibly fortunate to work with amazing colleagues, faculty, students, and staff, and I’m grateful for the experiences that shaped both my career and me personally. Now I’m looking forward to this next chapter in New York and to supporting the Climate School’s important work on climate and sustainability. The team has been wonderfully welcoming, and I’m excited to learn, contribute, and build new relationships. Thanks to all who have supported my journey so far, I look forward to staying connected.

Tim Tregubov reacted on thisTim Tregubov reacted on thisExcited to be back at Dartmouth College this week for the 70th anniversary celebration of the birth of the field of AI, right where it all started — Dartmouth’s campus. I’ll be speaking on a panel about AI and will also be a judge for DALI Lab's TechniGala, Dartmouth’s termly showcase of student-built technonogy with this term’s focus on AI-driven projects. I have fond memories from my time being part of the DALI lab, just when it was started. I led a project to build an Android app (for a startup I was working on) to connect students with tutors to improve learning support on campus. My passion for improving education goes way back! Interestingly, this visit coincides with my 10-year anniversary of graduating from Dartmouth. How time flies! I got into the field of AI during my undergrad at Dartmouth when I had the opportunity to join the Amulet project, which was developing a custom, open-source, energy-efficient smartwatch, before smartwatches were cool :) I did a thesis advised by Prof. David Kotz during which I designed and ran a field study to collect wearable data from students in daily life using Amulet, trained a machine learning model to detect stress, and implemented it to run on-device on Amulet as a wearable app — StressAware — for real-time stress detection. This thesis work earned me Dartmouth’s Neukom Prize for Outstanding Undergraduate Research in Computational Science, resulted in my first lead author conference paper, and news articles by Dartmouth about our work. Little did I know that this experience would become the launchpad for my career in AI. Over the next decade, I conducted research on wearable AI for health at Dartmouth and later at ETH Zürich, where I'm currently developing a wearable AI system to improve the management of rheumatoid arthritis—a chronic disease I live with—and also teach an AI course called #AI4Impact. Today, I continue that journey through my startup, Kwame AI, where we're building AI to improve education and legal service delivery in Africa. I’ll always be grateful for Dartmouth and its immense impact on me. “It is, Sir, as I have said, a small college. And yet, there are those who love it!” ~ Daniel Webster

Tim Tregubov reacted on thisTim Tregubov reacted on thisLast week, I attended Technigala—students from the DALI Lab, Magnuson Center for Entrepreneurship at Dartmouth, Dartmouth NEXT, CS, engineering, and digital arts inviting hundreds of people to explore, test, and dig into their work across three floors of Dartmouth's Engineering & Computer Science Center. This year's event was AI-themed (a fitting celebration of Dartmouth College's 70th anniversary of AI), with six prize categories focused on how students are building with and around it today. What I enjoyed most was hearing students walk through the journey: the decisions, the dead ends, the surprises. The depth of thinking behind each project was remarkable. The wins were part of it, but so was everything that came before them. Congratulations to the six winning teams, and thank you to the faculty and partners who make this possible.

Tim Tregubov reacted on thisTim Tregubov reacted on thisFour years ago, after my first ever computer science class, I wrote a program I had no idea how to finish. I'd just joined a hip hop team at Dartmouth College, and I watched my group put together a show the way nearly every dance team does it: a spreadsheet of names and arrows, frantic group texts, and one person holding the entire formation in their head. When a dancer moved or the count changed, it all lived in that one person's memory and a grid of cells. It was fragile, impossible to collaborate on, and disconnected from the music. As a brand-new programmer, I was sure there was a better way. I just couldn't build it yet. So I built a clumsy one: pure Python, circles on a screen, each a dancer that remembered where it stood in every formation. It barely worked. But in the docs I wrote myself a roadmap of everything it should one day do: easy project sharing, real-time collaborative editing, audio sync, custom dancer paths. I was dreaming big at the time, not knowing how to implement it. I just knew the problem was real. The idea wouldn't leave me alone. It followed me through multiple classes sophomore year, into a junior-spring course where I had a team finally helping me turn it into something people could actually use, and ultimately into my senior culminating project — 20 weeks, a new team, and a version I was no longer building just for myself, but for every dance group on campus that had ever suffered the spreadsheet. Wearing every possible hat alongside dancers, designers, and coders made the journey so much more fun, and I watched something I'd sketched as a freshman get hardened into software by the best team ever. That roadmap from 4 years ago? We built all of it and much more. Then came Technigala, Dartmouth's tech showcase which was all about AI this year. Out of six themed $1,000 prizes, ChoreoGrapher won Collaborative Intelligence — the category for tools where people and technology work together, with human judgment at the center. That was the prize that mattered to me. From that first clumsy prototype, the entire point of ChoreoGrapher was collaboration — turning the creative vision from one person into something a whole team builds together, in real time. Winning it didn't just feel like recognition; it validated the mission the project was built on from day one. The lesson in all this? An idea is only worth as much as your willingness to keep returning to it — and that once a team shares one clear vision, the work gets easy; you just have to start moving. Some ideas you finish years later. I know this one was worth the wait. ChoreoGrapher is live at choreographer.live. Built with Javier Rodillas, Valerie Gadapati, Griffin Speidel, Peipei Soeung, and Noah Jung.

Interesting work from our friends at AE Studio using Goodfire's technology - suppressing deception circuits increases claims of consciousness in AI models. This suggests that claiming consciousness in AI models is mechanistically gated by deception features found with the interpreter models we've trained. Check out their work here: https://lnkd.in/eQHPvhJf

This is real-time.. The debate about Nvidia's latest neural rendering tech is ongoing. One side sees the potential of the technology to bridge the gap across the uncanny valley, to give us a much less rigid creative process than a to b to c.. the other side shouts "slop" and tries to shame any creative who dares to explore this new technology, any chance they get. Meanwhile, I'm over here saying "I told you so".. Gen Ai is here to stay, its becoming real-time and Nvidia now has the "RTX on" for AI which I've been talking about for years. We need creatives to help shape meaningful tools that combine this tech with much more granular creative control.. with tools where you as an artist see your creative thumbprint from beginning to end in the parts of the work that matters the most to you. If you're shaming artists or storytellers who embrace these tools, you're doing them a disservice in my opinion. If they don't learn to utilize these tools and workflows, to make them their own and to shape them, others will. There's no way this tech won't be a huge part of the creative industry and of the way we tell stories. It's happening around us as we speak. That said, at the core of it, do what makes you happy and create in any way you like. Don't let people tell you that "you can't do this" or "you have to do it like this". I made the video here by combining Krea.ai's realtime ai editing tool with a feed of me sculpting and building in Dreams, a creative sandbox/game engine on PS5 and 4 that lets you sculpt and build pretty much anything you can imagine in a very intuitive and "hands on" way.

Conference proceedings are a sneaky-hard quality control problem. Take AIPP - 100,000+ articles, hundreds of conferences, compressed timelines, distributed review (papers coming in from every direction). Still, same expectations: don’t let obvious quality and integrity issues make it into the published record. Stout task! Super jazzed about the work with AIP Conference Proceedings and Alchemist Review: helping teams spot citation/reference issues, manuscript quality problems, and integrity signals earlier, so human attention goes where it can actually help. Excited to see this moving 🚀

“Anthropic leaked 500K lines of Claude Code source. Competitors got the blueprint. And Anthropic will still win. Here's why. # The Claude Code Leak: Why Anthropic Wins Anyway On March 31, 2026, Anthropic accidentally shipped 500,000 lines of Claude Code's source code to npm. Competitors got a free engineering education. Hackers got a roadmap for exploits. Congress started asking questions. And yet-Anthropic is going to be fine. Better than fine, actually. Here's why the company that just leaked its crown jewels will still dominate AI coding tools.”
