LG G3 Android adb USB debugging access

I have spent much time trying to develop software on my Fedora 21 machine with this phone.  I would always get "No devices found" from "adb devices" or no text at all from fastboot.  Here is what it took to get it to work:

USB debugging for this phone is done in the usual way: via Settings, About Phone, Software Information, then tapping Build number repeatedly.

Ethernet mode must also be enabled via Settings, More..., Mobile Broadband Connect to ON.

Finally, to install software via adb: Settings, Security, Unknown Sources must be enabled.

Accessing the Rigol DS1054Z Oscilloscope via TCP

After several attempts at searching for how to access my DSO via TCP, I finally broke down and did a port scan.

The first thing I noticed was that the scan locked up my scope... but not before finding several open ports.  Most notably, port 5555.  I reset the scope and carried on.

Armed with the DS1000Z Programming Guide from their website, I was very quickly controlling and reading from the scope!

$ telnet 192.168.1.40 5555

The Programming Guide has all the details.  Most notably, it appears that data capture is always returned as a subsample of 1200 points; you don't get the whole buffer.

On the plus side, it seems reasonably fast, so it's likely to be good enough for most purposes... you'll just need to get the USB stick out when you want the complete buffer contents.
