I would guess that most folks would consider a bunch of problem prompts with no reference solutions to be not so useful. How would you check your understanding? How would you know if you were writing go code which would be frowned upon by industry veterans?

I suppose all sites that have a voting component run the risk of becoming unpleasant.
Hacker News, and we who frequent it, ought to have that in mind.
I think it has more to do with the fact that when you offer zero salary for moderators, you have to take what you can get, and it ain't good. I don't really see a connection to the voting mechanic.

The measurements you are linking to are showing the level of distortion (HD3 v level) not dynamic range! The Y-axis on the graphs is showing the 3rd harmonic in dB in relation to the mV given in on the x-axis. This has absolutely nothing to do with dynamic range and it is also not the signal-to-noise-ratio. The fundamental frequency in those measurements was at 315 Hz. HD3 refers to Harmonic Distortion at 3rd level.
My bad. This Wikipedia article has a table of SNR values for 13 different kinds of tape: https://en.wikipedia.org/wiki/Compact_Cassette_tape_types_an...

Source? AI content without it is less than worthless.
Did you actually try any searches? Or is this just an excuse to broadcast your feelings about AI?
The author of the Ogg format claims a bit more pessimistic range of bit depth: https://www.youtube.com/watch?v=cIQ9IXSUzuM
Here are some measurements of type I, II and IV:

> Type IV
also they are 20$ per cassette :)
Wow! And Type I are about $2.80 on amazon. That's quite the span!

I stopped using my smartphone for about 1 year now and bought a walkman fiio cp13, it is really cool, but it is really hard to make a good sounding cassette, particularly if you dont know what you are doing (like me).
I record stuff from youtube and make mix tapes.
I am experimenting with "not getting what I want the second I want it", e.g. "I want to listen to XYZ", 1 second later I click on spotify and its done. Now I have to wait, first XYZ might not be on the cassette I have with me, or it might be 5 songs later, and I dont want to waste battery rewinding, sometimes I rewind with the pencil if I am really desperate.
But the feeling of excitement when the song you wanted comes up is really nice :)
Some people recommend the `rewind` player instead of cp13, as it also has bluetooth.
We have forgotten how `not to get things NOW`. It took me a while to get used to it. There has to be some minimal amount of effort for a `thing`, when you go below it, it just becomes nothing. Maybe thats just me.
> but it is really hard to make a good sounding cassette
It is unfortunate that cassettes are the lowest fidelity consumer medium (of modern times). But there is some room to optimize within that space. If you are curious:
The cassettes available today are Type I, Type II ("high bias") and Type IV ("metal"), each being higher fidelity than the last, but not all portable players supported these types of tape.
Dolby B/C noise reduction could improve the dynamic range of tapes a bit, but again not all portable players supported this.
The ultimate was "dbx", which dramatically improved noise reduction and dynamic range ("tape hiss" was essentially inaudible), but now you're in the territory of needing dedicated rack-mount equipment to record and play your tapes.
My dad was a bit of an audio buff, so I got to experience these things as a kid.
Edit: according to gemini AI:
* Type I had a dynamic range of about 50bB (roughly 8 bits)
* High quality tape with Dolby B, C and dbx yielded roughly 65, 75, and 85dB SNR (about 11, 12.5, and 14 bits)
So you could get pretty close to CD quality, but not quite.

According to Reddit's "Staff Platform Engineer (Web Platform Team)":
--- start quote ---
Old Reddit has the advantage of being pretty much static non-interactive content. No video, tiny thumbnails, and barely any JS or styling. Some people like this and some don't, but the end result is a very lean website that performs well out of the box.

Suffice to say, I'm on the frontend perf team and we're acutely aware of these problems

This was in October 2024.
Which is of course a bunch of bullshit when you consider that Reddit's backend returns most data in under 400ms, and it takes Reddit frontend 3+ seconds to render it
It could be that they are just incompetent.
Based on how universally horrible their video playback performance is (even in the iOS app), I can only assume incompetence.

Companies intentionally make their web experiences worse because they can track you better in apps. Even if the trackers are technically the same, even somewhat savvy people using blockers or browser protections generally don't use them on their phones.
This is a satisfying narrative but I feel like you are overestimating the technical competency and/or malice of these companies. The more likely explanation is that they have simply bitten off more complexity than they can chew.
Of the tech companies I've worked for, I can't even imagine how the web team would react if they were instructed to intentionally nerf their website.

I think it's part of the test to have to do it quickly.
Sorry, I meant I want to be able to do it faster. I don't want to be held up by an automatic progression.

"do nothing" is too slow, need another key to hit to skip.
I would expect a final reaction time of under 100-200ms ideally?
Yes, I would also remove the automatic progression entirely. This should be driven by user input only.
