> Some puzzles have rebus answers, where more than one letter will fill a single square. It’s not obvious when this is the case.

Another deviation from the "one letter per square, all in a line" that they sometimes have is the bent answer. I recall one for instance where there were several isolated black squares, and some answers that ran into these continued after a 90 degree turn. So you might have 5 spaces to the left of the black square, but the answer was actually 9 letters with the last 4 written upward from the black square.

As with rebuses, they don't tell you that a puzzle has this sort of thing. You are left to figure it out on your own. For that 90 degree turn example, you'd probably get it by filling in enough of the words that cross it to notice that the 5 space section matches the start of a 9 letter word that would work, and notice that the 4 letters that would complete that word are going up from the black square. That seems unlikely to be a coincidence, and then you'd go look at other places where the answers seemed to short and see that same trick works there.

I don't think I've seen any the have both rebuses and non-linear answers. That would be a nightmare.

Having worked with both systems, Debian CI does not focus on system integration. Fedora CI and Debian CI are more similar than different, but Fedora also has an OpenQA instance for doing the system integration testing as openSUSE does. openSUSE's main weakness is that they don't do deeper inspections of RPM artifacts, the dependency graph, etc. They don't feel they need it because OBS auto-rebuilds everything on every submission anyway. The Fedora CI tooling absolutely does this since auto-rebuilds on build aren't a thing there, and it's done on PRs as well as update submissions.

These sort of graphs always manage to surprise me with these hidden patterns that the brain thinks it recognises but never seems to be able to pinpoint.

Wish I knew what to do with a library like this in a personal project. Sadly, mathematics isn't exactly my biggest strength...

If anyone has any cool graphs or visualisations with hidden patterns or meaning to share I'd love to see them. And to stay on topic and to not hijack the thread: bonus points if they were (re)created using OP's lib :)

There's a bit of a rabbit hole to go down about the question of ages in Genesis, touching on some neat topics such as Base-60 counting systems used by ancient Sumerian civilizations. Here's a nice start : https://www.youtube.com/watch?v=uoPbZnRN8xQ
If one addiction is bad enough, using something less addicting to break the cycle can be effective. If, for example, an hour of video games a day breaks a dopamine chain that keeps an hour a day of phone time from turning into four hours a day, it's still a net positive.

That's assuming they find games hyper-stimulating. Personally I can count the number of hours I spent last month playing video games on one finger - even though I used to play 30+ hours of video games a week in school - because it doesn't reward the long term investment circuit anymore. HN on the other hand? That's "career development."

Can you be more specific? I've heard the argument, for example, that cell death is a defense against tumor growth, but we do not observe that across all living things - we have Peto's paradox where large animals have almost no incidence of cancer.

I'd be really hesitant to try to attribute any one specific reason as to why we age, or why that has benefited some life.
agreed that pivoting can be a pain.

a pattern that i converged on --- at least in postgres --- is to aggregate your data into json objects and then go from there. you don't need to know how many attributes (columns) should be in the result of your pivot. you can also do this in reverse (pivot from wide to long) with the same technique.

so for example if you have the schema `(obj_id, key, value)` in a long-formatted table, where an `obj_id` will have data spanning multiple rows, then you can issue a query like

```
SELECT obj_id, jsonb_object_agg(key, value) FROM table GROUP BY obj_id;
```

up to actual syntax...it's been awhile since i've had to do a task requiring this, so details are fuzzy but pattern's there.

so each row in your query result would look like a json document: `(obj_id, `{"key1": "value", "key2": "value", ...})`

Hello HN! Author here. I was thinking to call the post "The underappreciated complexity of musical sounds" but decided to stick with the DFT one as it would probably get more attention. This is a small discovery I came across this weekend. FFT-based spectrograms of musical instruments isn't a novel thing do, but I thought what if I do a super highres spectrogram with a continuum of freqencies, instead of the N fixed ones FFT gives. Turns out, FFT "supports" such frequency shifting by multiplying the input by a specially constructed complex exponent. As a result, I've found out that musical instruments produce sophisticated ornaments in between the harmonic levels.

Quit some TikTok, Twitter, Instagram and fb for starters. They make are the “easy” drug dealers of the internet
Three hard steps:

1) Remove your twitter, facebook, etc. accounts.

2) Throw the iphone through the window and buy a bad phone that works with your bank (or better, change bank). Silence all alerts except the critical (persons that may need your help urgently and you care, and stuff like that).

With those two you'll end up scrolling through whatsapp profile pictures and stuff like that but that's not going to hook you for more than few minutes, believe me.

3) Find something appealing on the physical world. Something that does not need a mobile phone. It will be hard because, for example playing guitar doesn't have a team of engineers thinking how to make you practice forever, but at some point you'll start getting interested by life again. Program raspberries to turn lights on, or similar, if you definitely need some device.
Not who you asked and I'm not a fan of BTC, but generally a fixed quantity of measure is helpful when trying to evaluate worth.

The fixed value acts as a measuring tape against objects, but instead of measuring length you measure value. When you measure to cut an inch of wood, you need the measuring tape to keep the length of an inch constant. If an inch were to shrink or expand at will it would be difficult to figure out how much wood to cut. Because BTC is infinitely divisible it acts like a retractable tape, allowing for as much room to measure as needed.

>why a currency where you don’t know how much you’ll able to buy with it in the future?

A fixed quantity helps with this. If your currency is free-floating and relative to others you can enter into different periods of relative purchasing power. Zimbabwe, Japan, Wiemar Germany, and Venezuela are all popular examples of floating currency behavior which can oscillate wildly.

It has teeth but high standards. It is a bit more like Treason charges in the US. Technically a capital crime but often not worth trying as the precedents make it a high fence to clear. You are better off finding some anticompetitive business practice to cease.

I hope it doesn't disrupt the Gates Foundation. I know there's people there doing really impactful research with good progress. It would be a shame for those labs to wind down due to Bill and Melinda's split.

I'm a generalist with a unique mix of skills - I’m a Full Stack Web Developer with an eye for product design, while also being fairly competent at technical writing. I have been involved with open source for the last year, and a lot of my work is available publicly: https://www.gethalfmoon.com (I built the project, wrote the docs, and I'm currently maintaining it). Recently, I have more available hours to work, which is why I am posting this. However, I'm open to discuss employs of all sorts: full-time, part-time, project, freelance, etc.
I think it's because time just happens, so it's easy to not think about how you're spending it compared to spending money, for instance.
Moderators de-ranked my post on Ayahuasca by changing the title

I think the problem is different.

Nobody should work that hard.

Not just for the sake of our children, but yes for their sake. But for our sake, for the sake of everybody.

We all need to spend more time working on our relationships, smelling the flowers, tasting the tastes.

We have one life and one life only. Getting into a competition about how we waste it on commerce is tragic.

Some people feel a need to work work work obsessively. IMO that should be viewed as a mental illness and needing treatment.
That is really sad. Always admired their partnership. You just never know what’s going on in people’s lives.

I wish them and their family the best.

> If you know exactly what you want, sure SQL is the way to go.

I've been doing similar aggregations with MongoDB, simply because when I start a project where I quickly want to store data and then a week later check what I can do with it, it's a tool which is trivial to use. I don't need to think about so many factors like where and how to store the data. I use MongoDB for its flexibility (schemaless), compared to SQL.

But I also use SQL mostly because of the power relations have, yet I use it only for storing stuff where it's clear how the data will look for forever, and what (mostly simple) queries I need to perform.

I've read your comment as if it was suggesting that these kind of articles are not good, yet for me it was a nice overview of some interesting stuff that can be done with SQL. I don't chase articles on SQL, so I don't get many to read, but this one is among the best I've read.

To get back to the quote: How will I know if SQL can do what I want, if I don't read these kind of articles?

Sometimes a tiny win can satisfy just one crucial customer. Once upon a time I joined a contractor development team with a strained relationship with their customer PM who a) represented the project to the wider organization and b) controlled the purse strings. This PM felt like the dev team wasn't listening enough to him or delivering enough.

My particular project had a simple web UI, and all the PM wanted was a feedback link added, and he was frustrated that it wasn't there yet. Although this was trivial and not critical at all to the application, I made sure to get that link up on the page - it was nothing more than a link to a feedback form or a mailto:, it was basic.

Anyway, the PM was super happy when that link showed up. It definitely wasn't because this was some whizbang new feature, or scratching some itch that had been annoying a lot of people. It was because the team showed that we were listening and responsive to him. That's a win, too.
I apologize for my cocky reply.

I just meant to point out that SoA vs AoS or an even slower data structure is not necessarily relevant for all programs.

> The main perf problem with using linked lists in high level languages is not the fact that they cause cache-incoherent access, it's worse, it's the fact that they allocate and deallocate memory constantly which is much much slower.

This is not true though; at least the JVM most definitely doesn’t do that, and I’m sure other state-of-the-art GCs neither, like V8.

First of all, allocation is basically free, much faster than malloc and friends. It’s only a pointer bump. And the cost of deallocation is amortized/may not even happen. With plenty of memory available, GC doesn’t really happen, and for long-lived objects in case of a generational GC, they may not necessarily get checked at all after a time.

So the usual linked list gets appended a few times is close to optimal, iteration has the same cost as in lower level languages with pointer chasing (usually a bit more because objects usually have headers that take quite some space, less of them potentially fitting into cache). It even has some advantage in that a modern compacting GC may move the objects close to each other.

> Life in Singapore during the pandemic has become about tracking, tracking, tracking. Wherever one goes, one has to scan QR codes that log entry into malls, restaurants, shops and office buildings.

Heh. In Israel, and even before the pandemic, the political police (the "Shin-Bet") has the cellular operators save your location history (indefinitely? who knows) for them to query for their shady ends, and sometimes even for regular police to have access to.

During the pandemic, this was used to retrace movements of sars-ncov-2-test-positive people, and to inform people they were in contact with they should self-quarantine. The funny thing was that the quarantine had a bunch of loopholes, and you don't have to carry your phone with you, and nobody would check up on you, and the airport was basically wide open until early this year, so the whole clamp-down was half-theatrical and we got the further legitimization of mass surveillance without even the potential upside.

(Now, In Israel, things have improved because of vaccination, not other reasons; but the government won't allow the Palestinians in the 1967-occupied territories, the ones without citizenship, to get vaccinated, so they're not faring that well.)
Ill take it a step further: I think child rearing is incredibly difficult if both parents are entirely focused on their careers and view them as their top priority.

I think it works out much better if one of the parents is much more low key about their career and can shift focus away from it more easily when emergencies / etc happen.
