YouTube Part-14 what is a session

Part-13 showed snapshots of a session and rollback. Part-14 is a technical description of what is meant by the word "session".

You can take snapshots and rollback to any version or snapshot. You can also roll-forward.

There is also a webpage introducing Easy Version Control:

YouTube video Part-12 app finders

I created this video as a tribute to Roger Grider, 'radky' on the Old Puppy Forum. He created PupApps, PupControl and JWMdesk, for Puppy Linux, that formed the basis  of EasyApps, EasySetup and EasyJWM in EasyOS. The first two are launched via the "apps" and "setup" icons on the desktop.

Roger has retired from contributing, but still around, and, I reckon, still using Puppy Linux! Well, he was working on a next-generation Puppy, so most likely using that.

Improved hardware profiling for audio

Hardware profiling is one of the unique features of EasyOS. It remembers the hardware setup when you bootup from a flash drive on different computers. Or even on the same computer if you change the audio card.

The concept is introduced the "How and why EasyOS is different" page:

https://easyos.org/about/how-and-why-easyos-is-different.html

Audio profiling was the first implemented, back when Quicky Linux was based on ALSA, not pulseaudio. Back then, I reluctantly adopted pulseaudio, as it was becoming increasingly required.

The script /etc/init.d/10alsa implements audio hardware profiling, but as have moved more towards embracing pulseaudio, the script has fallen behind. Today fixed it. Previously, it was recording /etc/pulse/default.pa for each hardware configuration, and now have added /root/.config/pulse.

What happens is copies are created for each hardware profile, for example /root/.config/pulse.0+pci+8086:7e28

Video encrypted folders & session saving

In response to a request in the comments section of one of the videos, I have created a video that shows what folders are encrypted. It also explains the basics of session-saving and how it can be configured.

Maybe might make the next one a look inside the 'initrd', which will be of interest to developers.

phoneCam Android webcam

I have created a simple application to use an Android phone as a webcam. Snapshot:

For more information, I have created a YouTube video:

"EasyOS Part10: Android phone webcam"

Quite nice, but I will probably go back to using GUVCView and the laptop internal camera.

Zarfy monitor manager missing icon

Forum member Miminou reported the missing icon:

https://forum.puppylinux.com/viewtopic.php?p=173158#p173158

Zarfy is provided in a PET package. I rebuilt it with the missing icon.

Audio hardware profiling fix

When EasyOS is booted on a USB drive on different computers, it is supposed to remember the hardware setup for each one; this is called "hardware profiling".

A special string is generated, that identifies the audio hardware on the computer, but it wasn't working on my Zenbook laptop. It is /etc/init.d/10alsa that generates the audio hardware string.

I found that this "lspci -d ::0403 -n" had no output. "0403" is the class ID for audio devices. I discovered that there is another number, "0401" which is also a class ID for audio devices, see here:

https://admin.pci-ids.ucw.cz/read/PD/04

So, have modified 10alsa script, at line 228:

   AUDIO_IDS="$(lspci -d ::0403 -n | cut -f 1,3 -d ' ' | tr ' ' '|' | tr '\n' ' ')"
   #...ex: 00:1b.0|8086:1c20
   #20260701 zenbook laptop, audio device has class 0401 ref: https://admin.pci-ids.ucw.cz/read/PD/04
   if [ -z "$AUDIO_IDS" ];then
    AUDIO_IDS="$(lspci -d ::0401 -n | cut -f 1,3 -d ' ' | tr ' ' '|' | tr '\n' ' ')"
   fi

There is still some audio hardware profiling to do, as it was previously based on running MSCW (Multiple Sound Card Wizard) that is now deprecated.
