Re: Ideas for the next WLUG meeting

by John Stoffel

Josh, This is a great start for a talk, I really like your example of setting up duc, though you don't need to build the cache yourself with tcbmgr, duc should do that itself on startup. I may borrow your docs and testing things out and update the duc docs as well, since I think what you've done here is really neat. Looking forward to trying to make the next meeting, though December thru February will be tough for me due to other commitments. John

Josh, I think this would be an awesome talk. I'm particularly interested in the /sysroot upgrading process. I like the idea of having an immutable root that you can unwind things if they go horribly wrong. I'm game for having this as our Dec. topic! Thanks, Tim.

Ideas for the next WLUG meeting

by Joshua Stone

Hey everyone, I'd just like to say I had a fun time at Thursday's meeting! I'm already looking forward to the next meeting as I'm sure there are plenty of interesting topics we could discuss. As mentioned before, I think we could examine technologies that'd be beneficial to Linux on the desktop, like comparing packaging technologies including Flatpak, Snap, and AppImage. I think we could also look into the future of containers on the desktop as a whole with projects like Flatpak, toolbox, podman, and Silverblue. My workflow over the past few years has been using these upcoming technologies as daily drivers as they lead to saner development. For example, my laptop runs Silverblue ( https://fedoramagazine.org/what-is-silverblue/) which is a Fedora variant designed around immutability where a new system image is committed as the new /sysroot without affecting the state of the running system. This is reminiscent of Android A/B updates, although the update backend -- ostree -- has elements of a version control system like git. Toolbox ( https://docs.fedoraproject.org/en-US/fedora-silverblue/toolbox/) is also interesting as it lets you switch into an unprivileged development environment that can be built up and torn down without affecting the host as tools are installed inside a container. For example, I can build and install duc inside a toolbox without actually installing to the host /usr: [jstone@jstone-laptop ~]$ toolbox create --release 31 --container duc- test [jstone@jstone-laptop ~]$ toolbox enter --container duc-test ⬢[jstone@toolbox ~]$ git clone https://github.com/zevv/duc ⬢[jstone@toolbox ~]$ cd duc ⬢[jstone@toolbox duc]$ sudo dnf --assumeyes install gcc make autoconf automake pango-devel cairo-devel tokyocabinet-devel ncurses-devel ⬢[jstone@toolbox duc]$ autoreconf --install ⬢[jstone@toolbox duc]$ ./configure ⬢[jstone@toolbox duc]$ make ⬢[jstone@toolbox duc]$ sudo make install # no password needed ⬢[jstone@toolbox duc]$ mkdir ~/.cache/duc ⬢[jstone@toolbox duc]$ tcbmgr create ~/.cache/duc/duc.db ⬢[jstone@toolbox duc]$ duc index ~ ⬢[jstone@toolbox duc]$ duc gui Finally, I've been installing most of my apps as Flatpaks, which uses the same file storage backend as Silverblue to manage apps and shared runtimes. This app distribution technology allows you to decouple apps and operating systems as everything is built and run inside a sandbox, making upgrades easier. Compare needing only one version of an app to package as a flatpak, versus packaging for different versions of distros: https://flathub.org/apps/details/org.clementine_player.Clementine https://www.clementine-player.org/downloads I'd be glad to hear what everyone has to say! -Josh

Re: Reminder: Meeting today! Nov 14th, 2019

by John Stoffel

I'll be there tonight, and I can show off the boards I designed and had made with KiCAD too, if people are bored about ZFS. :-) Maybe in March I can give a talk on using KiCad and show over version 2 of my board design to address the mistakes I made first time around. John

Re: [EXT] Photo Frames

by Joel

I have a 10 inch simple mode, no wifi or touch screen, pictures fed by sd card sneaker net. Device was around $70 on Amazon recently. Can share the specific model tomorrow if people are interested. Actually support three picture frames, one at each grandma house too. Update photos onto 4gb sd cards twice per year. Works great for a random screen saver like show. All can see the transition of our cute kid into a gangly tween.
