We started producing shows as Today with a Techie on 2005-09-19, 16 years, 4 months, 16 days ago. Our shows are produced by listeners like you and can be on any topic that "are of interest to Hackers". If you listen to HPR then please consider contributing one show a year. If you record your show now it could be released in 6 days.
We are running very low on shows at the moment. Have a look at the hosts page and if you don't see "2022-??-??" next to your name, or if your name is not listed, you might consider sending us in something.

Layer Modes, sometimes called Blending Modes, allow you to combine layers in a variety of ways. We continue with the Inversion Modes, which in various ways invert the lightness and the color values of the component layers. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

In this episode of your favourite FLOSS podcast our two OAPs discuss the challenges of running
conferencing systems like BigBlueButton behind a network address translation
(NAT) configuration, something that the Inlaws have been struggeling (?) with
for quite some time but now have arrived a solution which might just work :-).
If you face similar challenges or just want to refresh your knowledge about
intricate network architectures never mind their pitfalls, stay tuned. All
will be revealed (hopefully :-). But beware: This show is highly technical and
geek-only. Which may come in handy if you're not technical but suffer from
insomnia or similar sleep disorders - this is your show!
There are multiple guides online as to how to install, but I found dnf install android-tools.x86_64 adb-enhanced.noarch the easiest. Similar commands are available for the other distros. Use your package manager to search for adb.
Go to Settings. Usually via the pulldown menu from the top twice, and click the cog icon. Search for 'Build Number', it's usually in Click on 'About Phone' Click on 'Build Number' seven times.
Go back and then search for 'Developer options' it's usually in the System section
You'll need to turn on two features 'Android Debugging' and 'ADB over network'
While we are at it, go back and then search for 'IP Address' it's usually in the About phone section. You should see a IPv4 address eg: 192.168.1.100. Make note of the IP address as we'll use it later.
To get help use the command adb help
global options: Tell you how to connect to the phone
general commands: Shows your devices, and gives help
networking: Allows you to connect over the network but also to port forward and reverse traffic
file transfer: The only reliable way to get files to and from your device.
internal debugging: Shows how to control the server
Plug your phone using a usb cable. There will be a notification and a popup to allow the connection.
Run adb shell and all going well you should see your phone. Commands like ls, cd, and find work well. For example find /storage/self/primary/.
Unfortunately if you unplug your phone you no longer have a connection to it, but you can enable network access via tcp. Leave your phone connected to USB and then tell it to use a TCP/IP connection with the command adb tcpip 5555.
Then connect to the phone using the phones IP address and port 5555, adb connect 192.168.1.100:5555. It should reply with a connected to message
$ adb connect 192.168.1.100:5555
connected to 192.168.1.100:5555
Now commands like adb shell should allow you to access the phone even if it's not physically connected via usb.
Got multiple devices then you can connect them all in the same way as shown above. The only issue is you need to tell adb which one you want to address.
The first thing you need to do is list the devices
$ adb devices -l
List of devices attached
192.168.1.100:5555 device product:XXXX model:XXXX device:XXXX transport_id:9
192.168.1.101:5555 device product:YYYY:ZZZZ device:ZZZZ transport_id:14
The important bit is the transport_id at the end. You can then use the adb command as normal but specifying the -t option
-t: allocate a pty if on a tty (-tt: force pty allocation)
So for example adb -t 14 shell would connect to phone YYYY
So that's it for remote control from the shell, but what if you want to see and interact with the screen itself ?
scrcpy is a free and open-source screen mirroring application that allows control of an Android device from a Windows, macOS, or Linux desktop computer. The software is currently developed by Genymobile, which also developed Genymotion, an Android emulator.
# target dir is ~/Photos/YYYY-MM-DD_Hm
# create the dir
# cd to dir
# kill all gphoto stuff
pkill -f gphoto2
# get the files
# delete all files on camera recursively
