I'm pretty happy that they didn't, because silently replacing one operation with a similar operation that inevitably has different bugs and different ways of handling edge cases would be pretty frustrating. Letting both live side-

It is particularly infuriating in R, because lm(y ~ ., data = my_dataframe) already means "regress the variable y on all other columns in `my_dataframe`." For big, interactive regresions, it's really natural to write

I've thought about this a lot, and the easiest rule of thumb is, "buy something consumable." Like chocolate, notebooks, wine, etc., that's one or two steps nicer than they'd buy for themselves. (Or than you'd b

It is a kind of backwards reasoning that students empirically screw up all the time. Edit: so much so, that I would definitely recommend students rewrite these proofs on assignments as an exerecise to make sure it's correct. By the tim

I sort of agree, but your advice is targeted at an entirely different group of students than the article's. If someone is confused about how to interpret sin^2(x) vs sin^{-1}(x), there's no amount of "understanding" that

Those upper division math classes are pretty painful regardless. The material is just innately hard in a way that's dissimilar to most other hard things.

If your budgeting process relies critically on the number of characters being a good proxy for the value of a service, I don’t think acronyms are the problem. :)

Yes, 100%. In the parent's example the system should be fixed so that no one can push directly to prod. Failing that, some sort of standardized checklist/process should be put in place. That's true regardless of who personall

I've been reading this site for almost 10 years and never noticed them until you just pointed it out. I don't think many people look at the footer. :) (They're also not in the footer of the comment page and a link in the othe

That's most of the reason for the first item: "don't ask for a job, or approach these conversations with the goal of getting a particular job." Many people, introverts included, would want to be approached by someone g

You're not alone, but I also think that (like most of us) you're setting the bar higher than it actually is for what a "network" means. You posted a question on HN and look at how many people are willing to put effort in

I plug my full sized USB keyboard into my monitor, along with my yubikey and wireless mouse dongle -- one USB C cord connects it all to my laptop. edit: two monitors is still a pain, though.

That sort of comparison is a bit overrepresented on hacker news. The community in general seems to have a healthier perspective. :)

You're combining "email" and "mailing lists." I totally agree about the value of mailing lists, but well archived mailing lists don't seem to be an option in many companies. Email w/out mailing lists c

Voting something up because you want it to appear higher on the page seems like about the most rational way to use voting. :)

That device looks fantastic for what the author wants. Another approach if you need a little more flexibility in the software might be using a deliberately limited old laptop. (I'd rather type in emacs, for example.) Battery life would

I didn't downovte, but asides like, "sounds awful" and "nasty" definitely read as judgemental. Your other comments on this thread make you seem much more open minded than this one did.

From TFA: “Whenever a new invariant comes along, we try to test it against the Conway knot,” Greene said. “It’s just this one stubborn example that, it seems, no matter what invariant you come up with, it won’t tell you whether or not the

Not to put too fine a point on it, but that problem resisted years of “fresh eyes,” “related expertise,” and “recognizable human effort,” but she still walked in and clobbered it. Some types of success aren’t very relatable.

It's a great story. I'm curious what you think everyone can learn from it, other than "geniuses can occasionally solve longstanding intractable problems very quickly."

No — they’re useful for you (presumably) which is enough reason to keep them. But they’re useful documentation too. I’ll usually search for “todo” as part of evaluating a library because it highlights what’s missing as well as the developer

Some employers may do that. But, from the github profiles I’ve looked at, I’ve found that writing an ok README file and any coherent inline documentation or comments would put you in the top 5% of job applicants. Even if the code itself is

Pattern match —- ask yourself “what questions have been useful at similar points in similar meetings” and ask the context-appropriate version of those questions. (If they haven’t already been answered.) If this comes up a lot, come into mee

I may have gotten it from there, tbh. That first step looks familiar.

Since public schools closed, I've had my 3 kids (11, 8, and 8) practice typing 30 minutes every day. Easily one of my best parenting decisions ever. :)
