Backing up and restoring data on Android devices directly via USB (Howto)
From the author:Sat Dec 31 18:28:25 2016 - permalink -
"I was looking for a simple way to backup data on Android devices directly to a device running GNU/Linux connected over a USB cable (in my case, a desktop computer).
Is this really so unique that it’s worth writing a new article about it? Well, in my case, I did not want to buffer the data on any “intermediate” devices such as storage cards connected via microSD or USB-OTG. Also, I did not want to use any proprietary tools or formats. Instead, I wanted to store my backups in “oldschool” formats such as dd-images or tar archives. I did not find a comprehensive howto for that, so I decided to write this article."- https://blogs.fsfe.org/kuleszdl/2016/11/02/android-data-backup/

Rtl Power: Basic scripting.
Rtl_power is a unix-hacker's approach to the waterfall. Its unique features include:Wed Jul 13 04:10:50 2016 - permalink -
- Unlimited frequency range. You can do the whole 1.7GHz of a dongle.
- Unlimited time. At least until you run out of disk for logging.
- Unlimited FFT bins. But in practice I don't think I've taken it above 100k bins.
- Quantitative rendering. Exact power levels are logged.
- Runs on anything. A slower computer will use less samples to keep up.
The blog has a lot of other interesting articles, e.g. http://kmkeen.com/tiny-code/, http://kmkeen.com/flash-recovery/ , http://kmkeen.com/fp/ just to name a few.- http://kmkeen.com/rtl-power/
