In this version, the sheep all get stuck in the corners and edges. This doesn’t happen in the Fable version.
All public infrastructure benefits the public but the role of our governance is to correctly prioritize. $100 billion spent on nuclear power plants is $100 billion being withheld from other critical social services.
Typically you store a hash of user passwords instead, then when logging in you hash the user password client-side and compare the hashes. This acts like a one-way function that protects the password while letting the user authenticate themselves.

Read through the McMaster catalogue.

My coworker was given this advice when they first started their mechanical engineering and design job. They originally thought it was some kind of hazing and after an hour of reading couldn’t put it down.

I noticed that the dots on the surface of the sphere are evenly spaced out close to the equator, but because there is a consistent number of dots in each ring, they are very close together when you reach the poles.

One way to get dots evenly spread out over the surface of a sphere is to use a phyllotaxis spiral pattern.

Having valuable natural resources historically seems to be a big detriment to stable democratic governance.

Reminds me of a side project of mine called “Imperfect Circle” which makes asymmetric swung beats

I think they make a totally fair critique. The quote you pulled out is specifically about the fact that battery replacement alone takes 162 pages to get through.

They also describe the manual as “ they’re in-depth, mostly logical, and well worth an additional repairability point” higher up in the article.

For most of the pandemic in the US it's been about that easy, but right now specifically it's very challenging to get tests because of the Omicron surge

Proof by inductions often involve showing that Pn implies Pn+1. That is, that a statement's truth for n implies it's truth for n+1. That's what's being done here, and it's a perfectly valid part of this type of proof.

Re:The Anxiety of Influencers on Tuesday June 01, 2021 @10:47AM (#27355214)
I came across this article a few weeks ago. The 23% number seems to be from this poll https://morningconsult.com/influencer-report-engaging-gen-z-...

The author is mistakenly adding the 12% and 11% numbers. The real proportion is around 12% of young people. Given that in the poll, "influencer" is used basically synonymously with "celebrity" (Will Smith is considered an influencer) I'd say this is pretty reasonable actually.

Re:JamRTC – WebRTC for Live Musicians on Thursday March 18, 2021 @03:03PM (#26506288)
I built a similar project for in-browser jamming with midi-keyboards

https://github.com/jminjie/fourhands

The benefit of this is that it takes no set-up for non tech users. The major downsides are that it's only 2 player, and only works for midi instruments.

On Fourhands you can actually achieve very low latency (<20ms) with WebRTC for somewhat close players on wired connections. If you're having latency trouble like your readme says, I'm guessing it's not the WebRTC part.

The main classifier they use is using logistic regression, so no. They do mention that a deep nn had similar performance, but even if you deep-dreamed it you wouldn't get images, you would get feature sets, since they first run the photos through a feature extraction model (i.e. the input to the nn is not raw pixels).
Re:Malware on My Android Phone on Monday January 11, 2021 @11:44AM (#25731488)
I believe that actually does happen if you installed through Google Play Store, but in this case the app was sideloaded onto the device.
Re:Malware on My Android Phone on Monday January 11, 2021 @11:42AM (#25731458)
They mention at the bottom of the article that they did enable side loading, that's how the app was installed.

Unfortunately Firefox does not support MIDI access

https://developer.mozilla.org/en-US/docs/Web/API/MIDIAccess

But you can try it out on Firefox using computer keyboard input (letter keys ASDFGHJK)

I'm not sending all the MIDI data, just a simple 3-integer representation:

1. command 2. note (or byte1) 3. velocity (or byte2)

From testing you don't tend to get stuck notes (though in theory this could happen if a note-up command was lost forever and never sent), though you do see some jitter.

This seems to be using a central server as a relay (which is why they can have n participants). It works pretty well but the latency tends to be too high to actually jam. (Similar to my toy example at piano.jminjie.com)

Thanks for the share, have fixed.

Try making a new room, and also make sure there's only two clients in the room.

Since webrtc uses UDP jitter is occasionally an issue. If you monitor the ping on the site you'll likely see occasional jumps to 100-200ms every once in a while. These can cause irregularities in the rhythms but for the most part you can still make out the phrase even when there's jitter. (I think this is kind of like how we can read those scrambled word sentences because we read not letter-by-letter, but word-by-word.)

For a jitterlesss demo you can also check out piano.jminjie.com (central server, not p2p), where I've introduced an artificial delay so that the notes can be snet with timing info, and scheduled ahead of time to avoid jitter.

Latency can also impede a smooth jamming experience, but seems to be manageable in general when it's under 20ms one-way delay (I have been able to achieve this on a wired connection at 50 miles distance in the middle of the day). There's also relationship between bpm of the song and acceptable latency similar to the concept behind sampling frequencies (https://en.wikipedia.org/wiki/Sampling_(signal_processing)). The faster you're playing, the more latency matters.

Done, good catch.

Hey all, I put this together over the holidays after initial tests showed that delay around 10-20ms was achievable with WebRTC. The jams are only 2 person and only MIDI, but for that reason it's also fairly flexible and requires little set up compared to other options (see https://github.com/jminjie/fourhands for discussion on prior art)
