ah it's so fun when worlds collide. i own a strandberg (https://strandbergguitars.com/) - sincerely believe there is a huge amount of room for technical advancement in this space.
Man do I miss native desktop apps. This is so well done!
Something like this could be a Guitar Pro killer if it had support for writing a score/tablature. Imagine being able to commit changes to a score and have your bandmates pull it down and review, add to it, etc... it could really change the way we write music, especially in a world where you don't have to be in the same room to record an album together.
The article did not mention anything about skipping questions that were important to him; it specifically said that he had originally been picking questions "more or less" at random.
You're also assuming that the set of questions he had algorithmically selected did not overlap with the questions that were important to him. This seems unlikely.
The only dishonesty here is that by (presumably) determining the breadth and detail of his answers by order of importance to the cluster, he is in effect answering the questions /as if/ they are as important to him as they are to the average representative of that cluster. But if everyone else was also answering the questions "more or less" at random anyway ("He’d been approaching online matchmaking like any other user"), this doesn't seem so bad (and is probably why his algorithm gave him so many failed dates, since the relevant questions wouldn't have been answered).
Honestly all he did was make himself way more visible. You'd probably get a good amount of dates by making a sign and sitting in Central Park too. Sure, it's a bit distateful, but no less manipulative than that (and much more clever).
Even if you aren't into language learning it is a very interesting (and practical) read.
"Anyway, the short answer is this: timeboxing is a technique where we place deliberate, prior, artificial limits on the time to perform a given task. Within reason, the tighter (shorter) the time limits, the better."
I found this while browsing around the org-mode site, and thought this might interest people who turned off by (1) the horrible supermemo UI and (2) the lack of incremental reading support in the majority of other spaced repetition programs.
