This is a good place to use cumulants. Instead of working with joint characteristic functions, which gets messy, it lets you isolate the effects of correlation into a separate term. The only limitation is that this doesn't work if the moment doesn't exist.
I've also tried out a few solutions for this problem, but I inevitably went back to use slack or signal. The reason is that these messenger apps are just always open and it's far easier to paste stuff into it than opening an app dedicated to this purpose.
It's 80% clickbaity bullshit and 20% mediocre gadget reviews. Long gone are the days when Engadget was a relevant source of tech journalism. On a tangentially related note, does anyone remember Engadget's apple-only sister site TUAW? That was a great outlet for a good long while until Engadget started to shit the bed a couple years ago.
And bodies. Had to move my laptop dock to the other side of my desk when I switched headphones from a pair that had the transmitter in the left ear to the right.
Yeah that is perhaps the most problematic aspect of Bluetooth. The radio interface is designed with the presumption of the signal bouncing off nearby surfaces. Thus it is sensitive to line of sight issues.
Mind you, i have also been able to connect to a USB dongle through solid wood walls, so mileage may vary.
Never mind that you can get two classes of radios, on top of the LE stuff. With each class having different transmission strengths.
Both use the 2.4 ghz spectrum, so that makes sense - especially for bad microwaves.
I had an old microwave that completely tanked my 2.4 ghz Wifi back in the days (very poorly shielded).
I think it's a bandwidth issue. If I use bluetooth mouse, keyboard, and headphones at the same time, the mouse becomes very sluggish. It works totally fine if I turn off either the keyboard or the headphone.
I had no problem connecting a keyboard and phone (as modem) to a N800 back in the day, while also playing music from the phone to a pair of bluetooth headphones. But that was if i used PAN For the data connection between N800 and phone.
If i used DUN, either the music or the data would occasionally skip.
And that may well be what gives Bluetooth its reputation. So many choices for the various OEMs in terms of protocols/profiles, on top of a more complex air interface (channel hopping).
Given all of it, one may well be better off comparing Bluetooth to USB than wifi. As wifi is Ethernet over a single radio channel.
That's amazing, I have spoken to many people who have read the book, and I haven't met anyone who has even attempted it. I have tried it a couple of times as well, but I haven't been able to get it to sustain.
Actually I didn't know there was a book about that. I remember reading a post of a guy doing that here on HN though. I had some savings and an opportunity arose, after some serious doubts and thinking, I took the leap. But for those who have a startup or do freelance work, I think it's highly probable to be able to do it as well.
I have also a friend who does UI/UX web development who's been doing this for a couple of years too.
