Josh,
No worries. We're a quality of content over slick presentation every day of
the week. I'm sure it'll all turn out fine.
Later,
Tim.

I am leery of the allegiances of any politician who refers to their
constituents as "consumers".
Hey all,
I'm glad to be a part of this! I'd just like to give a fair warning
that my material is probably going to be rough around the edges since I
haven't had much time to prepare a slideshow. Honestly I'm thinking
that I'll probablyalternate between a slideshow and just showing you
some examples on my laptop.

I also cannot make it this Thursday due to a conflict.
See you all next month,

Dangit, I can't make the meeting this month, I've got a conflict I
can't get out of that night. Will there be any slides or anything
from the meeting?
John
Hey Everybody,
We've got a meeting this Thursday on December 19th 2019!
Location: WPI Campus Center Mid-Century room (our usual haunt)
Date & Time: December 19th, 2019
Our speaker this month is Joshua Stone. He's going to giving a talk about a
couple of cool technologies in Fedora! Josh provided me some details about
these innovations so I've mashed them up and included them below.
Silverblue: https://fedoramagazine.org/what-is-silverblue/
Toolbox: https://docs.fedoraproject.org/en-US/fedora-silverblue/toolbox/
Flatpaks: https://flatpak.org/
*Silverblue* s 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* 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.
*Flatpak* 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.
As usual, snacks and refreshments will be provided and afterwards we'll
head off for dinner to continue the conversation.
Thanks,
Tim Keller

Joshua,
The meeting is going to be December 19th this month. Details forthcoming.
Thanks,

If you have any comments or suggestions for the tool to make it
better, we'd love to hear it. I've got some plans for this winter to
update the code and do better testing, so maybe adding some flatpaks
(or directions on how to make flatpaks) would be a great addition.

I might make the December meeting, but the January and February ones
are right out since I'm chaperoning ski club on thursdays.

John,
Thank you for your input! I was unfamiliar with duc's UI when I first
tried using it, but now I'm much more proficient with it.
I'm more than happy to share my findings with you so that more people
can benefit from useful tools like this. Speaking of which, I've also
managed to create a proof-of-concept flatpak of duc which you may find
useful for learning the conventions of this app deployment technology:
https://github.com/joshua-stone/nl.zevv.Duc
I hope you can make it to the next meeting! I'm going to try to make it
to the next meeting as well, but it'd have to be well before Christmas
because I'll be on vacation for a couple weeks.

Tim,
I'm glad you feel that way about it!
The /sysroot upgrading process is one of my favorite features about
Silverblue, as you gain some of thebenefits of COW snapshots without
relying on a particular filesystem(example:
https://github.com/openSUSE/snapper). GRUB is also enhanced where
instead of selectinga different kernel, you're booting into an entirely
different /sysroot complete with kernel, libc, drivers,firmware, etc.
all of which are tagged under one discrete OS version string. This
design shouldmake bug fixing a lot easier as a user may only need to
attach the OS version string when filing a bugreport, and a developer
could boot up that particular version inside a VM. This update model
should alsoeliminate variance between "not updated" and "fully updated"
like we see with traditional packagemanagement where a package mirror
might not have synced all of the latest packages.
The rollback mechanism is also quite innovative, which Silverblue can
get for free by designing updatesthat perform the equivalent of `git
checkout ${BRANCH}`.
I'm sure there will be much to discuss when we get to have a demo.
