Web developer and development teacher. [1] At home, I'm a musician and general low-grade polymath. Currently working as a freelance developer and intermittent web development teacher. As a teacher, I've worked for Viking Code School [2] and Thinkful [3]

To be fair: titles and headlines are often written in the tense you used, often to give a sense of energy and intensity. In fact, this is the most common form in news headlines, like "Smith wins 2022 election" or "new…
Ah, OK. Now I wish it wasn't too late to edit my original post :) The stats on the CIRR site across schools did always seem a little... odd to me, with differences in outcomes too big to believe at times. Sounds like I…
For me it's simply a matter of convenience of searching; even pages with great and comprehensive docs can be hard to search. And the average is so poor that I often don't even bother to check if a particular project…
The easiest way to think about Tcl is simply, "it's a Lisp, but with strings instead of lists." It turns out that when you make a language like that, you end up something where your code looks and feels like a list of…
I've found that one a lot more common than the "Hello" thing, but I'm sure it varies by the team.
This is glorious. The only way I could tell with any confidence it wasn't real was the clean, modern HTML and CSS (get with the program folks, this should be non-validating XHTML 1.1!) Nice easter egg from the source…
Are there any online stores where we have good evidence that they have good practices around COVID-19? Despite the crushing demand, Costco seems like one employer that might try extra hard to see after the safety of its…
Huh, maybe his intro-level materials are far different, then. I'm not going to die on the hill that there's any connection; I don't even know whether he claims there is. But it at least seems that this specific stuff…
All good points. I don't know much about his actual higher-level mathematical stuff (I'm pretty bush-league about theory overall, really!) But I've heard that a lot of people in the music theory world say it's awfully…
For this, I would highly recommend the music theorist/composer Dimitri Tymoczko. His career project is to rebuild the basics of harmony from the ground up from (mostly simple) rules, closely based on how people hear. A…
Due to exactly this issue, an increasing number of languages have an operator just for "if exists and not null": the null coalescing operator[0]. What "exists" means depends on the language; it can be as loose as…
I also worry about the increase in security surface area. A ton of additional C-level operations exposed to JS in all browsers. What could go wrong?
Ah, interesting—thanks for pointing that out. That is practically the same thing. I only wonder if the fact that it's two dots tends to discourage it from general use for things like arithmetic, compared to a single…
Good question--just stack them up on the left on the same order as they appear in the expression, I guess.
I've always wondered if a good way to do infix would be to simply have the ability to mark an item with a character that means "move this to the front of the expression." Let's say the char is ":". Then this: (1 :+ 2)…
Forgive me if the answer to this is already widely-known, but at this point is Racket making a play to be a general-purpose, "batteries included" Lisp, rather than a stripped down tool for PLT stuff and making…
Richard Stallman is mostly known for his activist/politics stuff at this point, but he was also a heck of a developer. He wrote Emacs, GCC, GDB and glibc. I'm not sure if he was a total lone wolf, but my understanding…
The benchmark scores [1] he gives only stack it up against other embeddable engines. It cuts those to ribbons, but can someone who's familiar with JavaScript performance weigh in on how it competes with the most popular…
I've found a way to take this formula and make it into a very effective weight-loss diet. I've been at it for almost a year and have lost 20 pounds so far, and it doesn't seem like I'm going to have any trouble keeping…
Mastodon/Diaspora seems like a pretty good fit for a small and tightly-knit community like Old School Revival D&D. (Granted I had to Google that acronym to find out what it was, so I can't claim to know much about the…
In Tegmark's case, his hypothesis doesn't necessarily imply that consciousness escapes the laws of physics in any sense, even somewhat. He's simply arguing that consciousness is a state of matter, like liquid, solid or…
This is wildly conjectural, but assuming the "CO2 is causing widespread cognitive problems" hypothesis is true, I wonder if there are whole colleges whose student bodies are getting slightly worse grades because of…
I think recommendation systems actually are pretty good at recommending stuff you already like. I think a lot of us tend to buzz right past those as "well, obviously I've seen that already" and don't take note that it…
Common Lisp doesn't have first-class maps (although lispm is right that you can think of lists as a thin abstraction around all kinds of data structures). But Clojure does have first class maps complete with their own…
I've heard that in recent years there's an increasing understanding that while achieving lucid dreams is very doable, full dream control is rare even with years of practice. (I'm pretty sure there's at least one journal…
