Hello! I am an Assistant Professor at the University of Texas at Austin School of Information and co-founder of coding education company Trinket.
As is idiomatic for these kinds of websites, here you can find:
A selection of press, interviews, and my non-academic writings is below. You can find my recent publications on Academia.edu and Google Scholar.
This paper presents an emerging theory of factors influencing the experience of encountering an autonomous quadruped robot, based on analysis of interviews conducted in our lab at Texas Robotics.
My doctoral student Yao-Cheng Chan was lead author and presented our paper at ASIS&T 2023 in London, England.
This work was supported by NSF grant #2219236 and UT Austin’s Good Systems initiative.
This paper presents a theory of the phenomenon of system-dependent truth using a performative approach synthesized from the work of Karen Barad and John Searle. I explain how things are made true by imformation systems by identifying the agencies of truthmaking and factmaking. I note the ethical issues that this theory helps reveal and point to ways that attention to agency in information systems provides a way of centering justice in information studies.
I presented a collaborative research on a laboratory of quadruped robot encounters at the 1st annual Trustworthy Autonomous Systems (TAS) Symposium in Edinburgh, Scotland. The paper reports that identifying the robot’s role and purpose are central concerns for participants and identifies methodological challenges of human-robot encounters research.
I was honored to present an update on the Living and Working with Robots Core Research Project at the 2022 Good Systems Symposium. In this presentation I use “ethical asterisks” to indicate areas of our research that spark ethical concerns, and “disciplinary daggers” to help translate the general terms I use into their field-specific forms when necessary.

Update: this post is now filled. Welcome to UT Austin, Boh Chun!
Come work with me! Applications due May 1, 2022, with an anticipated start on September 1, 2022.
“The Living and Working with Robots (LWR) project at UT Austin invites applications for a postdoctoral fellow who conducts sociotechnical research at the intersection of emerging technologies and real-world communities. As a Core Research Project of the Good Systems Research Grand Challenge, the LWR project’s mission is to build and study robot systems designed to benefit the specific communities in which they are deployed. The selected researcher will become a valued member of our multidisciplinary team, supervised by LWR Co-Lead Dr. Elliott Hauser of the School of Information. The fellow is expected to collaborate on existing LWR projects and to lead one or more independent research projects involving our site. An individualized mentoring and career development plan will include a secondary faculty mentor, chosen by mutual agreement, and peer mentoring opportunities with other UT Austin postdoctoral fellows. Compensation includes salary, benefits, and generous research and travel support.”
I’m a co-organizer of the Longitudinal Social Impacts of HRI over Long-Term Deployments Workshop at ACM/IEEE International Conference on Human-Robot Interaction, along with several other Living and Working with Robots Co-Leads: Justin Hart, Samuel Baker, Joydeep Biswas, Junfeng Jiao, and Luis Sentis. Invited speakers include Reid Simmons, Maja Matarić, Stefanie Tellex, and Selma Sabanović.
“As the world sees robots begin to inhabit places designed for people - delivery robots on city streets, and robots with jobs in airports, shopping malls, and in the home - we expect the importance of understanding these impacts to grow. By bringing together researchers interested in longitudinal studies on real-world human-interactive long-term deployments, we hope to arrive at a clearer vision of how best to study these systems.”
I am organizing an open panel (mini-track) at the 2022 Society for Social Studies of Science (4S) Annual Meeting in Cholula, Mexico, with EunJeong Cheon, Justin Hart, and Swapna Joshi. Consider submitting an abstract and hope to see you in December!
“Living and working in community inevitably occasions experiences of the other, and automated technologies form a new kind of ‘other’ layered into these complex spaces. Phenomena of life and work amidst new technologies are studied by many disciplines. However, have we fully understood how the growth of autonomous technologies within communities is reconfiguring each? Do we have the methodological tools and access to this phenomenon to even gauge whether we understand it? Can we keep the racial, economic, political, and cultural complexity of communities in view when studying automation?”
Peter Stone and I discuss the Living and Working With Robots cross-campus collaboration at UT Austin, funded by Good Systems, a UT Grand Challenge.
“Instead of saying, “We have this technology, let’s apply it,” our goal is to identify the right problem before we try to solve it with robotics. We’re prepared to hear responses like “robots don’t make sense here,” and we’re going in with open minds and expect to be surprised. What can library staff and patrons teach us about how they work and what they value? It’s a really different way of working that requires time, patience, and resources.”
“The University of Texas at Austin School of Information is pleased to welcome Dr. Elliott Hauser, who will be joining us as an assistant professor in August 2020. He comes to the iSchool from the University of North Carolina at Chapel Hill, where he earned his Ph.D. in Information Science in December 2019.”
“Author Miriam Peskowitz’s new book Code Like A Girl is a fresh take on learning to code, starting with Scratch, running through Python (via Trinket!), and ending with Raspberry Pi computers. Miriam first contacted us a few years ago about her project, and it’s been fun to get some glimpses behind the scenes as she’s worked to make her vision a reality.”
"”Java is a powerful language that’s been popular in education for many years. Like all programming languages, it’s often helpful for learners to work with images. The visual feedback that images give can be more engaging and more intuitive than text alone. Yet, many instructors don’t know that you can use Java’s built-in libraries to easily make your own images!
“In this quick post I’ll use the Java Trinket to create a simple image, a version of the Trinket logo. The code is based on an excellent example by Byron Kiourtzoglou over on Java Code Geeks.”
“Just like how spending money makes you feel rich but is actually making you poor, so the things that make you feel productive, like clearing out your inbox or having coffee with investors, are actually often doing little to get your startup where it needs to be.”
“I’m advocating for a view of life as a very very long period of time, or perhaps a series of long periods punctuated by periods where we’re not paying as close attention or our brains aren’t moving as fast. But still, I arrive at the same conclusion Graham does: we should ruthlessly edit out things that don’t matter, actively seek out and do the things that do matter, and, perhaps most of all, be present and savor the moment. There’s more possibility and excitement in the instantaneous moments we have direct access to each second than we realize during the day-to-day.”
“The median two bedroom apartment rent is now $5,000 a month in SF. The good news is that there’s an amazing hack to living in Silicon Valley: don’t. Instead, live in your current, cheaper, location and commute once a month for way less.”
“Increasingly I encounter students who’ve been through dozens of tutorials but are unable to code their own projects. I call this phenomenon the Tutorial to Nowhere and it’s the major challenge for Coding Education: how do we equip students with real skills, not just access to content?”
A video I recorded for O’Reilly, using Trinket. Users will build several interactive game ‘sketches’, all the while learning concepts like functions, classes, methods, and variables.
Thanks to Trinket this can be completed enitrely in the browser. Hope you enjoy!
“We are collectively poorer every time someone doesn’t solve an important problem because of lack access to the skills and support to do so with code.
Fighting for diversity in programming is fighting for the minds that one day will write programs I never could. If coding is a basic literacy, let’s work for an enriched authorship and a more varied literature than we have today.”
“Pick your serious hobby deliberately and it will round out your skill set while providing balance to a demanding schedule. Peter Thiel divides personalities into Athletes, who are natural competitors, and Nerds, who are creative explorers. We all fall somewhere along this spectrum but most endevors require a blend of these traits. Serious hobbies are perfectly suited for helping you blend.”
“The first rule of wartime is to accept you’re at war. The early stages of a business where you’re developing technology, acquiring new users, and refining the idea, can feel like peacetime. But this is a false sense of security. Many of the failures I’ve seen at startups stem from the founders never developing an urgency about their situation as a small company that no one has heard of and therefore no one cares about.”
“You’ve probably heard before from Athletes that the primary determinant of the outcome of a game is often something like ‘mental toughness’. This is absolutely true for Netrunner. Especially in a tournament setting, where you’ll play 6 or more hour+ games in a row, keeping a competitive edge is crucial. This is the most pervasive benefit I’ve derived from playing Netrunner, and playing it to win: familiarity with the must-win moment.”
“As I’ve grown up I’ve gotten a bit of a different perspective on the role that cards played in her life. I can now see that what seemed like a simple pastime was a force for gender equality, religious temperance, and intellectual stimulation for a woman who had precious little of each during her lifetime.”
“I see too many beginning coders apologizing for ‘just’ learning Ruby or Python or Javascript, as if they were cheating the system somehow. It’s as if there’s some ‘Serious’ coding that they’re not doing. The idea that some coding languages are more Serious than others is a myth that needs to be disproven.”
“Why? Getting ‘no’s requires you to do three key things that will help you get ‘yes’s over time:
This may sound like a dumb idea, since the point of pitching someone is to get ‘yes’s. Let’s dig in and look at the benefits in more detail.”
“Geoff Ralston recently wrote a post on his brilliant (b * d) / c formula for prioritizing product development features. You should definitely read his post if you haven’t. I call it Ralston’s Unified Theorem of Product Development.
As he notes in his post, though, the key to success with this formula is picking the right metric to use with it. Are there any more specific guidelines we can use to pick these metrics? I think so.”
“If I were rich I suppose I could use Doordash, Postmates, or other delivery services to bring great food to me any time I wanted it. But there’s still a lot of distraction and cognitive overhead in choosing food and I think I might still choose this diet if I were a billionaire. Like wearing the same thing every day, it’s a strategy for keeping focused on what matters.”
“Progress down the path towards excellence means being surrounded by the success of others. This can induce natural feelings of desire to experience others’ success ourselves. Combined with the illusion that others must fail for us to succeed, this generates envy. To avoid the destructive, isolating effects of envy, it’s important to consciously identify your own success with that of those around you.”
“I know that management frameworks are good for me and my team, but they’re just not very appetizing. So here’s an experiment in deep fried management.”
“To be sure, great products can overcome mediocre brands and great brands will certainly not overcome inadequate products. But if you’re founding a company, launching a product, or considering rebranding you have the opportunity to create a lasting advantage if your brand can capture your unique positioning in the marketplace.”
A shortened version has been pubished on Edsurge and the full version is scheduled to be included in Jessie Aurora’s Edtech Handbook.
“Humble companies know their place is to augment and amplify their customers, not replace them. Their products equip teachers and students to better do things in the classroom, rather than consume materials. More and more of the most exciting young companies are focusing on building tools for teacher and student success instead of hawking pre-packaged consumables. This isn’t just a coincidence, it’s also a recipe for success in the industry.”
“Luther College computer science professor Brad Miller is a true innovator and one of our inspirations here at Trinket. He’s the core maintainer for the Skulpt project, which we use in our Python trinkets, and has built one of the best free online computer science textbook collections around at interactivepython.org.
In this interview, we hear about how he got into teaching, his search for better, more interactive resources, and how he uses interactive tools (many of which he created!) in his own classroom. One of the themes that comes through is how his projects, like all software projects, are embedded within communities of contributors working to solve shared problems. We’re excited and honored to be a part of some of the exciting work he’s doing!”
“There’s a deeper insight here that I think most people miss. Code is a human language. We invented it! Yes, code tells computers what to do but it’s also how we communicate with each other about computers doing things. This has huge implications for teaching it and the kinds of tools we need to do so effectively.”
This talk is about finding and selecting the right tools for teaching code (esp. Python), for student levels from Beginner to Expert. I describe and rate several teaching stacks and do a hands-on demo. Hope you enjoy!

Elliott: How does teaching programming fit with the rest of the NC Museum of Natural Sciences’ education?
Walt: A key concept incorporated into the museum’s educational program is to provide science for a changing world. There are multiple facets of the educational program, but the VisLab is one of three Investigate Labs in the museum, hands-on interactive spaces where the public can engage in scientific methods and use tools employed by scientists. In the VisLab, we focus on data visualization, where we demonstrate multiple ways scientists use computer-based visualization techniques to understand data from various realms of science, and making with electronics, robotics, and 3D printing. Programming is the the unifying theme: the lab is a great example of the application of programming to varied subjects.
I was invited to be part of a panel on Python by Thinkful. Tons of fun and I enjoyed learning about the other panelists as well as sharing the Trinket story!
Elliott: We’ve been very excited to see you using our Python trinkets in ways we hadn’t imagined. Your blog does a great job of teaching both Python and computational thinking. What reactions have you gotten from visitors on the new interactive solutions you’ve added?
Mike: The response has been outstanding and I am moving all my solutions to trinkets. Live interaction with Python programs allows anyone to experiment with the results by changing a few parameters, and helps them discover new methods they hadn’t thought of before. My site’s traffic has doubled so far and is breaking records every month since installing trinkets. This has been a very exciting improvement in both exposure and blog usability.
“Teachers need to know that they can and should be part of the change that’s coming to education.”
“An instructor is, believe it or not, optional. It’s much more important to have someone who’s taught kids in your target age group than someone who knows a lot about programming.”
“When I’ve brought visual examples like this into classrooms, kids are instantly engaged. They can see that there’s something ‘in there’: the turtle. I’ve personified the variable, so they can realize that her name is ‘Tina’ and she’s the Turtle shape on the canvas. Their minds immediately leap to what else Tina could do. I’ve got their attention and we’re ready to dig into the example, change some of the code, and really understand what’s going on.”
“Python has been called a poetic programming language, so I thought why not try writing poetry with it? This is a bit of a departure, but my background in Art History always helps me look for the artistic applications of what we’re doing at Trinket. So here’s a generative poem I wrote in Python.”
“Well-developed tools for teaching are crucial to the spread of open source software and programming languages. Stacks like those used by the Young Coders Tutorial and Mozilla Software Carpentry are having national and international impact by enabling more people to teach more often.”
“This is the in-progress story of our new embeddable Python Trinkets and how we realized that making our best technology more accessible for our users can be a way to turn our competition into allies.”
An interview with Physics teacher Pat Counts.
“Pat: For years the printed textbook has typically been a central component of physics courses. But physics is a science of change, and static textbook pages don’t convey change very effectively. Computers have the potential to provide a much more dynamic environment for modeling change than do ink and paper, and the best learning takes place when students interact with the concepts they are studying.”
We just released interactive Python, embeddable anywhere on the web. Check it out below and create your own!
“Most students find a tool, write a piece of code, and at the moment that their programming becomes a real thing (a website, a robot program, a game), they’re hooked.”
- Greg Garner
Here are my three favorite interactive tools for teaching Python to students of all levels:*
5 things students need from a 1st language:
An active culture of studio visits amongst artists has been central to the development of artistic movements. Programming meetups can serve a similar purpose and are important tools for educators, especially those of us teaching in higher education.
Public displays of art have been essential to developing artistic communities throughout history. But at various points in history, groups such as Academies or Guilds controlled when exhibitions happened, who could show work, and what kind of work could be shown. In 19th century Paris, a group of artists organized a series of alternative exhibitions called the Salon des Indépendants that gave artists a direct outlet to the public and other artists, with no mediating Academic jury. Open source code has played a similar role in freedom of expression for programmers over the past few decades, and forms an invaluable tool for those of use who teach code.
It’s easy to get caught up thinking you’re trying to get something from an investor. This is a trap. My test of a good investor is whether they add value in the first meeting though their questions, analysis or advice. So why not return the favor? Find out what—or who—investors are looking for when you meet them and then keep an ear out. It’s that easy.
The best art history class I ever took was about Dutch art, taught on-site in museums and cathedrals in Belgium and the Netherlands. This process of cultural immersion is too-seldom replicated in programming courses. Yet it’s much easier to do with programming than with art history- the culture in question is still operating in the present! Later on in this series I’ll describe how Meetups and Hackathons are the perfect cultural immersion tool for teaching programming, especially to those with relatively little experience.
The overarching message here is that everything you are - your familial status, your race, your gender, your nationality, your professional background, your first language - feeds deeply into the kind of vision you can set for your company. The world needs more companies with more big, powerful, benevolent visions.
Finding, let alone keeping on, this middle path isn’t easy. When I talk with Venture Capitalists, most of their eyes twinkle when discussing technology changing education at scale. Fewer understand how learning takes place. When I talk with instructors, they’re obsessed with being better in the classroom. Few care to think about the mechanism whereby they learn of these improvements. Both groups are key parts of the equation we’re solving here. Our job is to integrate them.
Software is spreading into every industry, changing how established players must play and even what the rules of the game are. But while many in Silicon Valley and Educational Technology think that software will “eat” teachers, replacing many of them, at trinket we believe software’s role is to create openness, making teachers better and more connected. Far from there being less teachers in the future, we think openness will enable and encourage more people than ever to teach.
Today we announced that our forthcoming beta will include a new brand: trinket. This is a story of how our team has helped draw this renewed vision, new brand, and new product out of us by asking us important questions and challenging our decisions. It’s a story of needing to shake out of our comfort zone, and for me, personally, it’s required a shift from visionary to true leader. I hope it’s a story that other founders will find useful.
A conversation with ExitEvent founder Joe Procopio.
Joe:
The Startup Giveback idea came up at an event back in September. Elliott brought it up, and it had obviously been on his mind, during a conversation with me and Adam Klein over drinks. The idea is for the Triangle entrepreneurial community to create its own charitable fund, in the form of an endowment that will benefit local charities perpetually. It’s a big goal, which is why I like it and why I’m betting other entrepreneurs will like it.
*Despite the ambitious title, I can’t claim I know for sure how we’ll build education’s open future. But by examining the history of open source, I think we can see what shape the answer will take. And so this is the approach we’re taking with Coursefork: the hypothesis that the future of education looks a lot like the present of software and that both are inexorably becoming open.
There are three areas that we believe educators must develop if we are to make this future a reality: Community, Leadership, and Technology.*
“My original plan with Coursefork was to take the summer, go into a room with lots of Red Bull, and code a prototype. I’m not an amazing coder, so I estimated it would take me 2-3 months to get an alpha. In that alternate reality, I wouldn’t be writing this essay, I’d be trying to test out my prototype in front of users.
By building a team and giving the idea away to them, I was able to see a proof of concept built in a weekend, deploy an alpha in June, raise angel funding, and end up here at The Startup Factory.”
*What occupies the rarefied space of the 20% most important things for your startup? Things like understanding your customer, having a killer idea, and choosing the right investors are crucial to your success; you can’t win without them. So it might seem like you should prioritize things on a great big list and just work your way down from there.
A strategy that has worked for me has been to attack my Great Big List from the top AND the bottom simultaneously.*
</a>
I've started a startup called Coursefork with cofounders Eric Martindale and Brian Marks. We're an open education startup looking to become the foundation for education's open future, where educators of all types can create, share, and modify course materials for anything from a workshop to a university course. I'll be open-sourcing my materials for the graduate level programming course I'll be teaching at UNC in the fall on Coursefork. In the meantime, check us out!
*What are YOUR goals? This is the first question you should ask yourself when looking for investors. It’s the question I’ll leave you with, because it’ll take some time to think through.
You need to know what your goal is so that you can effectively communicate that goal. Plenty of investors will not be a good fit for you to achieve your goal, and that’s OK. Just make sure you keep the conversation focused on goals so that all parties can quickly evaluate whether a deal makes sense.*
Fun aside: this was published on the day we officially registered the business with the Delaware Secretary of State. We got our first term sheet a few days later.
Coursefork is in the midst of pitching to angel investors and we’ve learned a ton, so I thought I’d take the time write a post that can hopefully save you time and/or effort. There was a distinct shift for us a few months ago when investors started taking meetings instead of giving us the “keep me updated.” This is how we got there.
My wonderful wife Erin bought me a Raspberry Pi for my birthday in November 2012. It’s changed the way I think about computers and coding education. I wrote a long form post about my latest ideas on HASTAC.org. You can read more by checking out my G+ feed, and below are some selected posts from it.
I started Comp-core.org, the Computational Core Curriculum, to collect and collaborate on course materials (and code, via our github repos) for those of us who teach this material. It’s small now I first got this idea from a panel I moderated in the Fall at UNC called Code in the Classroom. A little wrap-up of that event, which featured profs from Duke and UNC, is here.
So check it out and shoot me an email or join comp-core’s open google group if you want to contribute!
Some G+ Posts I’ve written about the Pi:
Finally, see also this post on HASTAC, which is a longer case study of how my VNC project was enabled by the modern Internet.
Basically, HASTAC is a sounding board and sketchpad for ideas. Pretty much all of the posts I’ve written have felt experemental, tests of ideas. The reponses I get are always energizing, as I hope my comments are to others’ posts. Here is a case study in how posting some experemental ideas on HASTAC has blossomed into real-world expereinces, virtual connections, and tangible improvements to my ideas.
