Comment: Power delivery is good at data transmission. (Score 1) 208

From page 18 of this document: https://intel.activeevents.com...

"The PD communication channel is an RF system:
- 23.2 MHz DFSK with a nominal deviation of 500kHz"

So the VBUS/GND pair alone can be enough to transmit data than USB LS (1 Mbps) and USB FS (12 Mbps). I see this a a very interesting solution: a standard to deliver negotiated power and mid range data rate using only 2 wires. If only the USB PD will allow a broadcast topology, I see a lot of possible applications...

The frequency of the power delivery is so high that an antenna could maybe be enough to transmit wireless data, without power. LOL

I don't pretend that Nodejs is comparable to Tomcat or similar options. I just noted that restarting on an uncaught exception, while not included in the Nodejs environment, is technically nothing special in Javascript virtual machine compared to others language. I have do that with a manager application or script in many projects. I will probably try to use systemd to do that in the future.

I suppose that it's possible to find the same opinion for any language. Actually it seem that Node.js raise in popularity.

Personally, I use it with Qooxdoo, and I found it a more effective solution that PHP for example. Having the same language in the server side and in the client side make the whole thing more coherent and simpler to maintain. I now experiment it for it portability across platforms to control a testing device from a browser.

While I agree that node.js don't have a UI, it still have to balance the time passed to compile and the time passed to execute. AFAIK, node.js use a single thread loop for the execution and probably for the compilation too. I think that dispatching the compilation to a second thread could reduce the latency of the execution thread.

Good move.

While forking is a necessary fact to develop a new idea (even into the original community), merging (at lead idea) is even more necessary long term consequence to avoid fragmentation. The most dangerous thing for open source communities is to start to see others projects and communities as futile and without interesting for learning something.

Desktop related projects should really start to go into that direction now.
