In our Innards section, we talk OBS (Open Broadcaster Software)

And finally, the feedback and a couple of suggestions

LINUX INNARDS:

Livestream
- Easy mode option: mobile, and just use the app and hit the button (probably obvious)
- Perhaps second easiest option: No software at all – just use the web browser.
  - From a linux machine with audio/video source (webcam, microphone) just launch Firefox, go to Facebook, Youtube etc and go live from web browser (have done this on FB live, need to check this works in Youtube)
- JB
- Our BEST option, by far, and still pretty user friendly – OBS Studio!!
  - Some reasons to use
    - It’s FREE!!! Both as in freedom AND beer
    - Linux first
    - Multiple video sources
    - Stream gaming, screen recording
    - Add text, logos, etc to screen
- All I do is add one plugin
  - /home/leo/.config/obs-studio/
  - In the plugins directory, dump your plugin here!
- Plugins are not easy (or possible) in Flatpak. Possibly Snaps, too
  - /var/lib/flatpak/app/com.obsproject.Studio/current/LONGUUID/files…
  - This is where the plugins would be, thereabouts. Does not work!
  - Use the PPA if you want plugins.
  - Otherwise, the flatpak is easy enough for basic stuff.

VIBRATIONS FROM THE ETHER:

There is a website at devhints.io, and they have an amazing bash scripting cheatsheet…The other thing that is indispensable to me, add the following:

export HISTTIMEFORMAT=”%F %T “

to your .bashrc or /etc/profile.d/timestamp.sh. This will put a timestamp on every command when you do history.

…add the following lines to a file in the directory “/etc/modprobe.d”:

install tipc /bin/true

install sctp /bin/true

install rds /bin/true

install dccp /bin/true

[H]ere’s the high level overview.

Decide if you want a swap partition or swap file.

If partition, use Gparted on a Live Disk you have handy to create and format any empty space that may have been left over by the encrypted swap area. Make sure to format it as swap. Use the blkid command to note the UUID for usage later.

If file, use a Live Disk to create a file, named whatever you like, for instance “swapfile”, in / . Mark it swap by typing `mkswap /swapfile`

In either case, while still in the live environment, open up the /etc/fstab file in a text editor and add a new line.

if using a swapfile

/swapfile none swap sw 0 0

if using a swap partition

UUID=ADD-THE-UUID-HERE none swap sw 0 0

Save, exit and reboot.

Encrypting the swapfile or partition is another long email! Here is some light reading on the subject.

[There have] been a couple phones that come from the factory with dual boot for example:

as well as a couple of tablets

- Flatseal can fix the cursor issues!
  - For the app in question, under Filesystems > Other Files, add the directory that contains your mouse to your flatpak app in Flatseal and put :ro at the end
  - For me that’s “~/.icons:ro” (no quotes)

- Ubuntu Unity is still growing, along with sister projects Krob Linux for RPi, Ubuntu Ed and the new Ubuntu Lomiri. Lead dev Rudra Saraswat has acquired a couple new mirror sites, one in Russia and one in the US, in addition to their Mega.NZ, Google Drive and MediaFire download sites. They have greatly improved https://ubuntuunity.org and now they have a forum set up, to companion with their extensive Discord and Telegram groups. This is exciting stuff to be getting in on the ground floor of, and I recommend it.
- My latest recording (single) has been included in a Wizard Rock annual collection. It’s not rock, but it’s included. I’m not sure what the site for the collection is, but you can hear it at https://mordewis.bandcamp.com
