why not too often?

the brain is pretty expensive to run

I like list comprehensions now after having used the language for a while, but I will say they were the hardest for me to grok when I was first learning the language. even now it can be difficult to follow what's going on if you have nested ones.

I started enforcing type hinting in my personal projects. 99% of the time it's easy and useful to add. When I can't figure out how to make a mypy error go away within 30 seconds, I just disable it for that line. I feel this makes for very good 80-20 value/effort tradeoff.

I will say that more than one bug has been found after I disabled the single line hint though! Always surprising to me how powerful types can be.

1% of people commit horrible crimes? feels like an incredibly high percentage

maybe dentists wouldn't be lied to if they could actually tell if you floss or not. i always start flossing 2 weeks before my biannual cleaning and consistently receive glowing reviews from dentists on my dental hygiene.

feels like the whole thing is a racket

When contemplating a future investment into learning something, I like to consider the long-term benefits. Do we believe that command lines will become more or less important in the following years? My bet is that they will continue to fade over time, as they have been for years (decades?). I don't think there's much sense to invest more than the minimum unless there's a specific use case in mind.

Trane looks very cool. I think it's also a great idea to have example (guitar, rust) projects that show the tool in action.

How do you find yourself engaging with it? A big positive for me of Anki is the ease with which I can review a single fact (~seconds). It looks like Trane is intended for more dedicated situations, probably for ~tens of minutes at a time. Is that accurate? I'm basing this off of playing with the Rustlings example.

I have found this to be a huge missing piece of any SRSs I've come across. Personally, I have a pipeline that looks at what knowledge I've already learned and only then reveals successive information.

For example, I'm learning numbers in Spanish. First, I ask myself to go from doce => 12; then, 12 => doce. Then, once I have a few numbers in my memory, I can start to combine those into diez + dos = ? (answer doce). The idea is that this last example requires recalling three previously-learned Spanish numbers to arrive at the answer. This is a trivial example but this underlying structure of successive layers of knowledge shows up everywhere and is horribly under-exploited by our current learning systems.

Programmatically this can be done. Manually, this stuff takes way too much work.

Just to be absolutely clear -- you're claiming that nobody had any problem with Trump? Not sure what media you consume if so.

I actually had the opposite reaction -- on most websites I have to zoom in to 150 - 200% to get it to be readable (HN is at 175% for me). Here I had to do no zooming.

> Every node in your knowledge graph is a debt. Every link doubly so.

I do agree with the first part of this sentence, but I think that the second is a little more nuanced. The first few 'links' among nodes in a knowledge graph I do think generally represent more debt (probably less than the node itself, though). As the links increase and the knowledge graph gets denser, I feel that things start to flip and each individual node/link actually gets increasingly easy to recall.

For a specific example: learning how to conjugate a verb in a foreign language and learning a bunch of words out of context is going to be hard to retain over the long-term. However, combining those into a fill-in-the-blank kind of sentence once you know enough actually becomes easier and supports knowledge of all that you've learned. This is just a simple example but once you know about it, you start seeing it everywhere, regardless of the topic under study.

Anyway, I enjoyed the article. I have gone all-in on Anki and sometimes I get concerned that I'm missing out on the newest software. Articles that remind us that the best system is the one that you use are important to have around.

What kind of companies have you worked at?

I've been through many companies (and many iterations of the process in each of those companies) but have never experienced a case where this takes only an hour annually. Even as an IC you're going to be spending at least half a day on your own self-review. This doesn't even include peer reviews, upward feedback, or talking about the results of this whole process with your manager. In my experience, the process also doesn't just happen a single time per year -- it's usually twice (plus 'check-ins' outside of that).

I'm no fan of perf reviews but I have no idea how you could even run a process at all if you were to only give people 1 hour to do the whole thing end-to-end.

the reason a country may be corrupt isn't really that relevant if all you care about is a country's likelihood of being corrupt.

35 isn't really almost 40. plus he hasn't been the lead designer since he was 32.

so if something can be reproduced in no time it has no intrinsic value?

source?

i don't think anyone is claiming it's going to trickle down

it's interesting that it's very common to have a disdain / discomfort with showing that you have that money, but no such corresponding problem with just having it. if you're not going to give the money away, i don't see how there's any benefit to not spending. you're still way richer.

not in my experience. coming out of college, i worked for 3 years then took 18 months off. nobody i spoke to cared. if they asked about it, it was out of genuine interest for what i got into during that time.

Source?

yikes. I'd recommed trying to be less judgemental. there is no reason others should have to enjoy an experience the same way you do.

conversely i think it's great we're seeing more people able to take advantage of what we all collectively own.

unless you have access to some spring, i don't see how drinking bottled water in plastic is better than not drinking tap

shocker, company claims its own product isn't harmful

the hilarity of suggesting use of something from Amazon when the discussion is about avoiding health hazards...

It depends on how adept you are at creating cards, I think. If you have a non-manual pipeline that automates most of the work, I think the lifetime cost of reviewing a card a few times is comparable to writing out the same information out by hand. The difference with the card is that now this information is there for life, instead of for a few days/weeks with writing.

Agree that if we're talking about manual creation of cards, it can be hard to see the ROI given how much effort it typically takes to create high-quality one-off questions and answers.

I'm sorry, are you saying you have to be a user / customer of a business to be able to invest in it?

This already basically exists, with things like VIP / "meet and greet"

Setting aside the issues that revenue maximization is not typically the only (or even the main) concern for those selling tickets, I still think this system isn't very good. One key issue is that it assumes that the underlying value of the tickets themselves does not change over time (in the article's specific case, 6 months). But an artist's popularity can be extremely unpredictable, and over the course of 6 months could change drastically. This would likely mean leaving money on the table, especially if that rise in popularity comes close to the actual event date.

I think a better approach that could deal with this would be to avoid trying to come up with the 'max' and 'min' amounts and instead simply let people submit bids for how much they are willing to pay for tickets. You would pre-authorize that amount at order time, but it wouldn't yet be deducted. At the end of every day, the top n bids would 'win' and actually actually purchase the ticket.

In the simple case where the artist's popularity stays the same over time, this would probably result in a similar outcome to OP's suggestion. But if the artist undergoes a big increase in popularity, the ticket price would rise again to a much higher value later.
