I used to have a big problem with this. My family culture values slow, serial communication, so "cooperative overlapping" of the sort practiced at my workplace came across to me as rudeness. That meant my frustration at not bein

I lived in Botswana for almost two years, in the late 1980s. In my village there was a noticeable shift in housing style over time, as manufactured materials (cinder block, sheet metal roofs, chain link fence) replaced their traditional co

As shown, the minus sign is rendered as a hyphen. This looks glaring when you're used to math mode's thinner, longer minus sign. To see the difference, typeset this with LaTeX: \documentclass{standalone} \begin{document

The Errol Morris documentary "Fast, Cheap & Out of Control" has a segment on mole rats [0]. I think that movie would appeal to a lot of HN members -- it's broadly about people who obsessively pursue some interesting corne

Not saying your main point is wrong, but Black Beauty wasn't written to appeal to young girls. It is an urgent call to treat horses better, and has been called "the most influential anticruelty novel of all time." https:&

This is not what you asked for, since it still requires a separate file. However it might be close enough to what you want, and -- for complicated expressions -- possibly even better. You can write (or derive) the expression using sympy, t

It does make the code a little verbose, but in my experience with this (in modern Fortran), it can be rather nice. Explicitly tagging the construct you are closing makes it easier to understand long swaths of code (where the start of a loop

Enquist is one of my favorite authors, and Royal Physician's Visit among the many reasons why. That said, I have almost stopped recommending his work to others, as it seems to be hit-and-miss. Nobody I know hates his work, but nobody

Micro:bit has a lot going for it. Comes with a 5x5 LED array, an accelerometer, two physical push-buttons, three capacitive sensors, and a bluetooth antenna, already on-board. It means you can start programming without having to plug in to

My father worked for a large software company for many years. I remember him telling me how they successfully responded to a Request For Proposals with a much smaller proposal that said, in essence, "You don't know what you'

Try framing your material in the assertion-evidence [0] style. Not only does this lead to more informative presentations, I find it helps me organize my story better. Briefly, rather than using topic titles ("Experimental Setup",

Some time in the late 1970s, I heard a lecture by a researcher at the Air Force Institute of Technology, who stated that if you took Fourier transforms of an optical illusion, and then reconstructed the image while progressively dropping th

All three versions came from the Web site of Canadian author Robert Munsch. Hearing Robert Munsch read his own stories can be a revelation. He puts so much energy into the reading, in a way that kids seem to really enjoy. He also often

Sometimes, when a climate-denial comment on HN seems especially troll-like, and when I have time to kill, I'll look at the comment history of the apparent troll. Occasionally the person's comments only include political opinions,

I've had mixed results using Calibre ( https://calibre-ebook.com/ ). In all, I've converted 3 PDFs to Kindle format -- one is OK, one is a slog to read, and the third I forgot I was reading a converted version. Hav

Not only is the MS eqn editor slow, it also doesn't work consistently across versions of Word. I have a work colleague whose equations never show properly on my machine when he sends over Word docs. By contrast, LaTeX works the same e

There's a new-ish book, "Secure by Design", that makes this point -- and shows ways for ordinary devs to design for security without explicitly thinking about security. I really like this book so far (it's still in the e

This example shows a hazard of floating-point, but it does not show that the FP error is worse than modeling error. Here, the problem arises because the equational system is ill-conditioned. Yet you present the system as if the coefficient

You don't have to "hate rigor" in order to like non-technical treatments of a subject. One reason I like the book is it gives a high-level overview of what algorithms are available to solve a problem, and a sense of which is

Are QSS methods general and how do they compare practically to more traditional explicit time integrators? The original idea of QSS was to bolt an ad hoc step length control mechanism onto the most basic explicit method, forward Euler. S

If you're interested in circuit-like systems, Modelica is probably a good fit. Electrical networks seem to be a core use case for the developers/presenters of Modelica. Also I know it has been used to model airflow networks in b

Modelica sees a lot of use in building energy simulation [0], [1]. My impression is that the solver landscape is a little uneven (the solver reads a Modelica model and computes its solution). For one thing, open-source solvers seem to lag

I have a colleague who makes mind-map style notes, either on paper or via software. He doesn't try to capture everything that's said. Rather, he notes key ideas, and identifies/imposes structure to the conversation. It can
