I concur, what you describe is a very effective use of spaced repetition. It is different from what ‘ProstetnicJeltz described, where cards should take less than a minute to write — that describes memorization without first putting in the

> actively re-experiencing the thing you're trying to learn is a better way to make it stick On this we agree, but to me this means practical application in various contexts, rather than call-and-response memory drills.

Spaced repetition really clicked for me when I realized that it isn’t about learning, but about keeping memories fresh. If you don’t have an emotional attachment to each card in the deck, reviews become a terrible slog. Mine is a mix of r

Be careful with this, too. When somebody brings up problems they’re having, they often just want the catharsis of complaining and empathy about their situation. Proffering a solution, even couched as you have described, can change the con

It’s all about audience and confusion. My feel of the HN readership is that it’s a vey broad base of mostly technical backgrounds; international but US heavy. That puts the ones you list as perfectly reasonable, and CNN referring to the n

A spectrogram has time on one axis and frequency on the other, so the ultimate result is a multiplication in one dimension and a convolution in the other. It can be used to show things like when a note starts and stops in a piece of music,

I was imprecise and overly snarky in my original reply, and for that I sincerely apologize. I’d still like an answer to the half of my question that you ignored, so let me try again in a more neutral tone: In my experience, most instances

In my experience, the unqualified terms “consonant” and “vowel” unambiguously refer to individual letters, and the terms “consonant sound” and “vowel sound” are used to refer to the noises produced when speaking. Thus, most people I know w

They're both measures of importance, but evaluated at different times by different parties. In the article's formulation, the QA engineer sets the severity during the initial investigation based on technical criteria. This is th

Any business that runs into that sort of scaling problem is already doing quite well for itself. How many of them would have gotten to that point if they needed to hire a software engineer to make every prototype that eventually led to the

Make is an incredibly powerful tool for managing any automated process, not just software compilation. It doesn’t know how to do any of the individual steps itself, of course, but it lets you break down a process into indivdual small piece

Awk splits lines into numbered fields, so it’s really convenient for things like extracting and reordering columns from a csv file. For example, getting the second field of every line is: awk -F, '{ print $2 }'

The modern idea of a library catalog came around in the early 1800s, and probably accelerated the pace of knowledge transfer and acquisition quite a bit. In its original form, index cards, it was ubiquitous for almost 200 years before bein

Oh; you certainly have to be rich to pull this off. But the context was “a few millions in an index fund,” which is what your analysis came up with. Also, if you’re going to posit funds in other asset classes, you should also include the w

In Rust, that’s more or less the meaning of the unsafe keyword. It marks code that does things the compiler can’t verify as correct, but it’s always been expected that unsafe code will maintain the invariants the Rust compiler uses. This

by kd5bjo 7y ago
My apologies; I misread your original statement to imply that unsafe would necessarily imply undefined behavior.
475.
by kd5bjo 7y ago
Also, this is the primary reason that unsafe exists— there exists code that is both useful and correct but the borrow checker can’t properly verify. It’s a marker that tells the compiler it’s not responsible for verifying that code.

Yes, and extending that model to unsafe code. It would make violations of the model have undefined results, which allows the compiler to make optimizations that assume the model is followed even in situations where that can’t be statically

I may be just tripping over semantics here, but how can you consider data that may still be automatically rolled back to be “committed”? I thought that’s supposed to mean the data has been fully stored such that it can only be changed&#x2F

This isn’t correct. The calculation can be found as the worksheet on page 33 of https://www.irs.gov/pub/irs-pdf/i1040gi.pdf — regular income gets taxed first, and then long-term gains after. The 15% bracket only
