I’m honestly a bit surprised their comment doesn’t contain the user’s affiliate links. “Over-enthusiastic” users used to spam theirs everywhere.

• patents and yes, I believe so? Just like LDAC. Although AptX is very old, so most of those might have expired by now.

Transcoding to a (for them) transparent lossy result is perfectly fine if all you do is listen. I couldn’t care less about “audio qualities” that I cannot hear.

I should have been more clear: The negative effects of quantisation. Obviously sampling into discrete values is shown but not the negative consequences that can have.
A DAC interpreting the blue trace will output something extremely close to the red one. There might be a slight bit of error in it due to the quantisation before but the graph does not show that and it probably couldn’t since it’d be so tiny. A good way to show quantisation noise would be a histogram with a signal in the middle and some quantisation noise around it.

The DAC would not output the jaggy line. It couldn’t, that’s not a valid analog signal. Painting the steps between the points can be done if your audience knows what that means but can be extremely misleading if it doesn’t. Those lines between the points with 90 degree angles don’t exist in the real world, they’re just interpolated between the points in the visualisation.
A much better way to represent digital samples in such a chart is the way it’s done in the wikipedia article on the topic: en.wikipedia.org/…/Sampling_(signal_processing). They’re just discrete points. If you did the same interpolation between the points as a DAC would do (which is not nearest-neighbour interpolation), you’d get the analog trace shown.

I missed that you said in private tabs. I can reproduce it there but BW also says that private tabs support is still experimental when you try to do it.

Well, nothing’s changed.

You could argue that there have more/fewer audits.

I don’t have experience with the second point but the other two don’t happen to me; it works as it should.

It works but partitions can and will happen and a merge afterwards is non-trivial AFAIK.

Quantisation is a potential factor but the graph does not show its effects and their comment describes the supposed effects sampling, not quantisation.

Also, when we come to discussing SNR, you’ll have to consider the SNR of analog systems too.

“Didn’t understand the sampling theorem” for $2 please.

As long as the frequency of the measured signal is <1/2 the sample rate, you can reconstruct the original signal perfectly.

If you plugged this jaggy-looking graph into a digital to analog converter with perfect analog circuitry, you’d get exactly the sine shown.

Atemu , 1 year ago to linux in How to accurately measure laptop battery life in Linux?

Well, no program can accurately predict how you are going to use your laptop in the next hours. The best you can do is sample a given reference period and assume it’ll be the same but you have already noted the problem with that.

I’d recommend you monitor total power draw while using your laptop. It’s inversely proportiaonal to battery life: If you could reach 10h at 5W, you’d only reach 5h at 10W, 2.5h at 20W and so on; you can think of it as a metric for battery drain.

Atemu , 1 year ago to linux in What developments in the Linux world are you looking forward to the most?

Garuda only exists because the only way to distribute a set of default configuration in regular distros is to create a whole new distro/installer. We don’t have that problem in NixOS because all configuration is declarative and composable.

In the NixOS world, Garuda would be a NixOS base config which users would import in their own config and extend with their own configuration. You’d still be using NixOS though.

Atemu , 1 year ago to linux in What developments in the Linux world are you looking forward to the most?

from which interesting derivatives will show up.

I don’t think that will happen and hope it won’t because NixOS can handle the usual preferences people might have internally.

Don’t like glibc? pkgsMusl is the entire package set but with musl instead of glibc.
Want static compilation? pkgsStatic.
Afraid of systemd? Well okay, we don’t have that right now but I don’t think anyone would be opposed to optional support for worse service managers. It’d just be an opt-in toggle that we could support with enough people interested in it.
