Photomultiplier tubes, still pretty much the only solution for photon-counting applications.

I think in a lot of cases it’s the only tool for the job. I have a hunch that a significant majority of the machine instructions executed in a given second globally came from C source code, and a large portion of that is running on somethin

16- or 32-bit chars are pretty common on DSPs from any vendor. I’ve found that it’s usually only an issue with some cross-platform serialization libraries that make invalid assumptions about how an array of octets looks in memory.

How does Aragon's effectiveness for this compare to e.g a Google Docs spreadsheet?

So now there's some awesome PWA api giving you all those native features, and a permissions model, and so you install SUPERPHONE app, and that needs access to your contacts and to make and receive calls, and you say "ok, yeah this

Imagine you install $ANYTHING as a PWA. It's now on your homescreen, you launch it. You do $THING. now you switch to twitter. Now the PWA -- in the background -- loads some ad with an autoplaying video and now theres ad audio coming fr

I wonder if your customers would be happy enough without the speed upgrade if they weren’t wasting bandwidth downloading code they never wanted to run in the first place

I think its generally assumed that the unqualified term "floating point" is generally referring to binary floating point, which is not the same as decimal floating point. You don't want to use binary floating point for repre

You'd be surprised how quickly those 500 multiply-accumulates per autocorrelation point add up... a 128-tap filter * 500MAC/point * 2 channels(stereo) * 192ksps is already at 24+billion FLOPS for a single track...

That's fine, but being able to run multiple audio tracks worth of VST plugins in real time on a modest laptop is very likely more valuable to their target market

Polyphase filters maybe? It's an approach used primarily in resampling, and its an easy way to skip a LOT of Multiply-by-zero-and-Accumulate-ing

Don't worry, we only blindly pull in and execute "good" third-party code in your browser.

Probably because you don't have to worry about context switches in the middle of operations, since they happen at 'await' or 'yield's in coroutines, rather than whenever the OS task timer interrupts

According to NIST It's slightly more arbitrary than that: The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.

I think a lot of the time (in a jazz context) the chords are approached as almost individual elements or as part of a small "local" progression instead of in the context of the global key of the song, since the key could be changi

Well yeah, I figured that that's implied, the only times that really matter are the rising and falling edges of the clock.

A Rubidium reference gets you down to the 1us/day range, cesium gets you down to a tenth of that. It all depends how much you're willing to pay.

And what do you use to tell it where exactly it is during pre-flight calibration? They "require" GPS input in the sense that if I handed you an INS that was initialized/calibrated with some precision (Oministar/RTK/

From TFA: "Scientific language removes all the emotion, and people don’t understand it anymore." Right. We need more emotion and less "scientific" (read: precise) language when describing the results of scientific experi

As part of a larger system yes, but on their own they're only accurate for a while, as they constantly accumulate error. They require input from other sensors (generally GPS) to provide accurate location.
