  • Okay, just clarifying that you don’t mean the Beeper server, you mean the beeper desktop/mobile client. You can self host something identical to the server and use a the client that Beeper’s client is based off of, which is very similar.

    Self-hosting may become even more like using Beeper’s server and client soon, as I expect they will not continue development on the old android app and just work on the one currently in beta. The beta app feels pretty similar to element to me, so I’ll likely self host when they do that.


  • Yeah I tested it out. The feature in ARD that I am referring to is that you can do any of the main functions (observe the screen, copy a file, install a file, run a terminal command, shut down, etc) to any number of computers at the same time. You just shift click command click to select multiple computers and then press the button associated with that function. That you can’t do is control multiple computers at the same time, since that wouldn’t really be practical, but you can observe all of their screens and then double click on one of them to start controlling it.

    Really the most useful thing here is the ability to send an arbitrary terminal command to multiple computers at the same time, which you can’t do in Remmina.













  • I work in audio and had a thesis in DSP, so I’ll try to explain this. It is an interesting idea, and in some cases could work, but wouldn’t be practically useful in most.

    So there’s 2 types of audio encoding: Lossy and Lossless. All audio starts as lossless, and in many cases is converted to lossy to reduce the file size. The processing for this is NOT like compression, and is somewhat context aware in that it removes frequencies you wouldn’t hear because something else is more present and causing your ear not to really hear it (this is called masking).

    If you were to upscale something that is lossless, it would probably work. Barring any inter sample peaks, you’d be inferring additional points in a waveform and that’s fine. They’re actually some audio plugins that do this as an intermediate step when processing a signal.

    If you try to upscale something that is lossy, you can’t recreate what was removed, because there isn’t a way to infer that information anymore. It would be like if you were trying to upscale a photo but you’d already removed a dog that was somewhat obscured by a man’s hand. Even if you upscale the picture you can’t add the dog without somebody telling you that it was there before removal.

    The other part of the equation is “why?”, and while I’m a bit of an audiophile and I have my collection of lossless audio, the limitations of the system are typically the human ear. CD quality, (16-bit at 44.1 Khz), is really all you’d ever need. Most people can’t hear above 20 kilohertz (if you’re over 18, you’re lucky if you even get close to that). In digital audio, you can reproduce any frequency in equal to or less than half of the sample rate. With 44.1Khz, that frequency is 20,050hz. If you want to go really crazy, DVD quality (24 bit at 48Khz). I consider anything about that nice to have from a archival and measurement standpoint, but there’s no point in terms of human listening.
