You will be asked to write. Think about your writing process carefully and be open to new ideas about how to approach it.
Writing is, at a minimum, a two-step process: you write, you edit. Writing and editing are distinct steps. Don’t try to edit your writing as you write your first draft; you’ll trip over your own creativity. Get your ideas down, then edit. Then get more ideas down and edit them.
Ideally, you would repeat the writing-editing process several dozen times to further refine your prose. After you’ve written and edited your work, you’ll need to share your draft with others, who will edit it and rewrite portions of it. Set your ego aside. Focus on improving the writing and, through that experience, your default writing style.
Are there problems for which the best possible approach is to perform a brute-force search of every possible solution?
During the Soviet-era, the perebor problem (перебор) addressed this question. There are connections here to the question that arose in Western computer science: P versus NP. That is, is the set of problems that are easy to verify the correctness of necessarily also easy to solve?
The Golden Rule relates the perebor problem to Communist ideology: a desire to believe that some problems rightly require effort and that the search for shortcuts—also known as more efficient solutions, as were pursued in the west—was anti-Marxist.
Whether or not one decides to anthropomorphize complexity, it has long fascinated me that the “East” and “West” divisions of the 20th century carried over into the conceptualization of fundamental properties of computational complexity.
When a learner asks a question, I often hear their peers and teachers respond in a way that suggests “don’t ask that question; learn something different”. I see the same thing occurring on Q&A support boards all the time:
Questioner: “I was wondering how to cook an egg in the microwave.”
Supposed answerer: “Don’t use a microwave, use a pressure cooker.”
Supposed answerer: “Why would you want eggs? Go vegan.”
As an educator myself, I find it’s better not to say NO to someone interested in learning and instead say, “yes… and…….” to find out what interests them and connect the topic to their interests.
It’s a lesson I draw from the improv and acting communities: “no, but…” (or even “yes, but…”) stops conversations. “yes, and…” encourages them.
I’m often taken in by restoration and conservation stories. Recently, the thoughtful machine learning algorithms at YouTube suggested to me a set of videos related to Alec Steele and company’s efforts to install an industrial power hammer in their steelwork shop.
This is industrial equipment at a scale with which I have no experience. Yet, the sheer joy and curiosity exhibited by this crew as they work to address practical, physical, and design issues with making this equipment functional is glorious.
The Machine Stops, a story ahead of its time being published in 1909, foretells of a society in which individuals are almost completely physically isolated from one another in an underground enclave where communication is achieved only with technology and all life’s necessities are attended to by a vast, unseen network of tubes.
What happens when, as always must happen, the machine stops?
A good, dear friend recently inspired a journey into the world of radios, speakers, and design. I love nothing more than being challenged to consider deeply a topic that’s otherwise new to me and through that to broaden my understanding of what I value and enjoy.
The first computing device I remember using was The Little Professor (1976). Designed like a calculator, the Little professor worked backward: it presented unsolved equations the user then needed to solve. Many years later, future-me would see a Little Professor in a computing exhibit at London’s Science Museum and wish that past-me could have known.
My first programmable computer was the Timex-Sinclair 1000 (1982) with 2K of RAM. I don’t remember what—other than the low price of $99—spurred my mother to buy this for me. It was connected to a Radio Shack audio cassette recorder for data storage and the family’s TV in the living room via an RF converter switch for video output.
“Now, Therefore THE GENERAL ASSEMBLY proclaims THIS UNIVERSAL DECLARATION OF HUMAN RIGHTS as a common standard of achievement for all peoples and all nations, to the end that every individual and every organ of society, keeping this Declaration constantly in mind, shall strive by teaching and education to promote respect for these rights and freedoms and by progressive measures, national and international, to secure their universal and effective recognition and observance, both among the peoples of Member States themselves and among the peoples of territories under their jurisdiction.”
“Both students and instructors perceive standard-error statistics as a confusing collection of specialized tools. To improve student learning, instructors long for a reduction in the number of topics needed to support statistical thinking. This book is a roadmap for instructors who wish to simplify inference while continuing to teach using traditional tools.”
“I hope that this little book can help instructors see that statistical inference can be handled as one topic among the many needed for modern statistics. Inference, important though it be, does not need to be such a sprawling set of methods and details taking up so much of the introductory course that other essential topics get neglected.”
I like this recent GOTO conference talk about the role of linguistics in understanding the language of coding. It touches upon many issues I’ve noted over the years as well as newer-to-me issues in non-English programming.
“This Voyager spacecraft was constructed by the United States of America. We are a community of 240 million human beings among the more than 4 billion who inhabit the planet Earth. We human beings are still divided into nation states, but these states are rapidly becoming a single global civilization.
“We cast this message into the cosmos. It is likely to survive a billion years into our future, when our civilization is profoundly altered and the surface of the Earth may be vastly changed. Of the 200 billion stars in the Milky Way galaxy, some–perhaps many–may have inhabited planets and spacefaring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message:
“This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts, and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problems we face, to join a community of galactic civilizations. This record represents our hope and our determination, and our good will in a vast and awesome universe.“

Here, Charlie speaks to an issue that’s near to my heart and that too many people have forever gotten far too wrong: sex & consent. He speaks well and he speaks honestly. I commend you, lend an ear.
In this age of people doing awful things to one another and yet somehow justifying it to themselves, consent is fundamental. As humans, we should be able to discuss it and manifest it in meaningful ways.
The goal of issuer is to provide a simple issue tracker, hosted on your local file system, for those users who don’t want to or are disallowed from using cloud-based code repositories.
Online code repositories often provide an issue tracker to allow developers, reviewers, and users to report bugs, submit feature requests, and so on. However, many developers either choose to work offline or work on enterprise networks where use of cloud services may be prohibited.
issuer is an Add-in for use in RStudio’s desktop IDE. It works entirely locally with no requirement for a cloud service or even a network connection.
As an educator who advises students working on theses and dissertations, there’s a standard question I ask—I refer to it as “the PhD question”: So what? It’s a shorthand to challenge students to consider the question: If everything you’ve just said is shown to be true, what will that mean for changes in our understanding of the world or how we engage with it?
I found myself using So what? again recently at ICER 2019, a community of education researchers that values openness and community building. I heard myself saying it, and I realized I didn’t like the tone of it at all. So what? is confrontational. It’s a conversation stopper, not a starter. It’s a blockade, not an invitation. Yes, I learned it from my graduate advisors way back when, and I think it’s time to put it to bed.
