ldarby··on Electric shocks to the tongue can quiet chronic ringing ears
It still doesn't even make sense. How does something that "induces long term depression" have a separate effect of "reduces evidence of tinnitus"?

Are they saying this stimulation that apparently cures tinnitus also causes depression?

Oh this is bloody awful:

> we developed a guinea pig model of tinnitus induced by noise exposure ...

> choosing a stimulus interval known to induce long-term depression (LTD). Twenty minutes per day of LTD-inducing bimodal (but not unimodal) stimulation reduced physiological and behavioral evidence of tinnitus in the guinea pigs

https://stm.sciencemag.org/content/10/422/eaal3175

I'm not anti-science and I understand the need for animal testing to reduce risks to humans but this raises serious ethical concerns where no such risk to humans exists.

> Further testing in guinea pigs revealed the best body parts to stimulate to shut off tinnitus

How on earth do they know if guinea pigs have tinnitus and if this method shut it off in them?

ldarby··on Show HN: Parametric Equalizer for PulseAudio
Yes, I have strong feelings about clipping... For many years I was using the track Moby - Inside trying to find a hifi system or headphones that could play it without sounding crap, then discovered it couldn't be because it's clipped.

And thanks but I'm happily using my patch on a pure alsa system without pulse audio, and don't really have the time to spend on adding the equivalent to yours sorry. But I'd want to if only to spread awareness about clipping - it's not just music, there are also many Youtube channels that I unsubed from because of it (I did tell them but they didn't care).

Actually preventing clipping instead just detecting it (which mine does) is a lot of work - it would need to find the loudest frequency, then find the closest band and reduce that (while loudly informing the user, and oviously with an option to control it).

> clip without blowing out your meters

If the audio clips, and the meter doesn't "blow out", then in my opinion that is a defective meter.

ALSA already has an eq plugin (http://quitte.de/dsp/caps.html#Eq10) and I added this to it:

                if ((s > +0.99 && x[z1] > +0.99 && x[z2] > +0.99) ||
                    (s < -0.99 && x[z1] < -0.99 && x[z2] < -0.99) ) {
                        //clipped audio isn't exactly 1.
                        printf ("dsp/Eq.h:process(): input clipped :(\n");
                }
....

                if (
                    (r >= 1.0 || r <= -1.0) &&
                    (r < 20 && r > -20)) { //uninited memory?
                        printf ("dsp/Eq.h:process(): output clipped :( %0.16f\n", r);
                }
(one day I should try to get upstream to accept that or something like it...)

> These days, especially in EDM / Hip Hop, slight clipping in bass in somewhat stylistic.

No it's not, it's just widespread incompetence and has ruined lots of music I would have liked. Having better software tools that alert when clipping is happening would be a good thing (i.e. it needs to alert when crossing over from 0dB to a distorted wave form, not just hitting 0dB without distorting, which is fine).

It looks like it really is Zoom in the screenshots (but yes if it wasn't Zoom and someone called it Zoom, I think that would be terrible).
ldarby··on Physicists argue that black holes from the Big Bang could be the dark matter
The article was talking about asteroid sized (as in diameter), not mass.

https://www.wolframalpha.com/input/?i=black+hole+horizon+rad...

shows a black hole of mass 1×10^29 kg (which is about 1/20 of one solar mass) has a radius of 148.5 meters which is asteroid size.

https://www.wolframalpha.com/input/?i=gravity+of+1%C3%9710%5...

says at one earth's radius away that it has an escape velocity of 1447.5 km/s (kilometers per second), so yeah I think that will either destroy part of Earth or completely consume it, depending on how fast it's passing though.

For OP's question, whether it's detectable or not, it possibly is if it warps the light from background stars (same effect as https://en.wikipedia.org/wiki/Eddington_experiment).

How about not using the term "ROM" to refer to software images people install on to writable storage?
ldarby··on Youtube-dlc – Download videos from YouTube or other video platforms
To follow on, it's a valid point though. /bin/ls can handle different file systems because many other separate people/projects are responsible for the file system specific support (in the kernel).

Youtube-dl should be architected to allow many other people to own the site-specific support (i.e. via a plugin system, with the main "distro" of yt-dl including some popular plugins, which other people or themselves are responsible for), if it was like that then probably this fork wouldn't be necessary.

ldarby··on Youtube-dlc – Download videos from YouTube or other video platforms
This is misapplying the unix philosophy. There would be too much duplicated functionality between different tools for different sites. It would be like having different versions of /bin/ls for different file systems.

I guess it's fine to hold things like dry fruit but if you pour boiling water on it, I think the risk is if that could that leach something into the water?

Certified food safe epoxies exist but are expensive, e.g. ArtResin is one.

ldarby··on ReMarkable 2.0 – A digital notebook that feels like paper
Thanks, this was the question I had before purchasing, if they might decide to pull a Tivo in a future software update and kill off everything on https://github.com/reHackable. I mean, with enough resources they could replace everything with non-GPL3 licenses then lock it down, but that doesn't look likely, so I think I will go ahead and buy this.

Some of the projects on https://github.com/reHackable talk about having to be re-installed after upgrades, and other unfriendly vendor behaviour (e.g. https://github.com/reHackable/scripts/wiki/webui_invincibili...), which is slightly worrying, it'd be more assuring if they had better support for 3rd party software, or at least just a webpage saying "yes you can install 3rd party software, but note that it's not preserved over upgrades". The company I work for also sells a linux box, allows 3PS, and does have such a web page. Such a webpage might also cater to all the other people here commenting that their marketing dept is ignoring us.

> wireshark your connection

This isn't good advice for trying to show someone their messages aren't being sent in clear text. It could be encrypted using a weak cipher or have other implementation bugs that make it trivial for a nation state to decrypt it. You need to be able to look at the application's source code to tell what encryption it's using and if it's secure enough.

Yes but I've been in a situation trying to debug CUPS because it was corrupting fonts, and urgently needed a print out of something. So, pick your poison...
ldarby··on Windows 10 has “python” command that redirects to the Windows Store
I once shipped a python script with a dependency on the requests package, and installing that on the customer's system caused an outage on their production server with 1000s of users because of a permissions issue, that wasn't present in their and my test systems.

So, no more "use the system python" for me...

ldarby··on Office noise generator
I have these, for an office. Yes they are silent if you slowly push and release a key, but thumping away at 50-60 wpm still makes a huge amount of noise, even with o-rings installed (although a lot quieter than blue switches which I used to have).
ldarby··on Disproved Discoveries That Won Nobel Prizes (2015)
The whole point of the article is that it shouldn't be embarrassing. The current dark energy theory is just currently the best explanation for observed phenomena (or was, I'm not sure what you're referring to). Even if it's wrong, the Nobel is still deserved even just for making that observation, because it encourages others to pursue science.

ldarby··on The Sad Saga of Purism and the Librem 5
For the people complaing about closed firmware, remember that obtaining FSF certifcation can be achieved by e.g. cutting off the hardware pins to make upgrading it impossible, turning the "firmware" into "hardware". This is what the OpenMoko project did https://www.fsf.org/blogs/community/task2-openmoko. Is this what you would prefer?

ldarby··on Artificial waiting in user interfaces (2016)
The first thing I do on a new windows PC (and android phones nowadays) is turn off all the animations, menu fades etc. for an instant performance boost.

I wish I could also disable those lightbox image loaders on web pages that slowly fade in images, as if the webmaster was worried that displaying it too quickly might give someone a heart attack or something.

The public has been duped into accepting slow interfaces, and it pisses me off!

ldarby··on Zulip 2.0: Open source team chat
Hi Tim,

I just upgraded to 2.0 and was so damn impressed with upgrade code. I run Zulip in a VM with an NFS root, and hit some random NFS bug that resulted in this error:

... Found existing installation: cryptography 2.3 Uninstalling cryptography-2.3: Successfully uninstalled cryptography-2.3 Could not install packages due to an EnvironmentError: [Errno 16] Device or resource busy: '.nfs00000000016cef5200000f9e'

... `pip install` failed; retrying... ...

Then it succeeded, all by itself.

This is symptomatic of hiring people to do tech support whose only ability is to follow a script. Usually they can't even understand an if statement in the script. They lack the basic ability to think.

I work in tech support myself (L3) and am constantly shocked at the brain-dead, useless and actively unhelpful things the lower level staff say to customers.

ldarby··on The Art Institute of Chicago Has Put 50k High-Res Images Online
Yes, that's fine for images like that, that's several GB in size, but there's a cut off point where tiling becomes less efficient and slower than just downloading the whole image in one request, I'd guess it's around 1/2MB, which a lot of images on this art site are.

Even if the actual efficiency is no where near that, a 1080p jpg fits in that so it's not like people would want the IIIF functionality on images that small anyway.

ldarby··on The Art Institute of Chicago Has Put 50k High-Res Images Online
I think using IIIF is why this site is so broken.

Trying to load an image sends 50 separate requests, when the entire image is less than 400kb. This is the exact opposite of what web optimizers try to do, which is combine lots of small images into 1 large one and use clever CSS to show small parts of the image in the right places on the webpage..

You're forgetting what "easter eggs" are IRL - chocolate eggs hidden in a back yard that people have to look for.

The analogy applies to computing in 2 ways: they're hidden, and it's something desirable. Niether of those ways apply to what Mozilla did. Therefore it wasn't an easter egg and you trying to pretend otherwise is just confusing.
