I'll check the valuable information.

Subject: ELCE 2020 event now open to all

Hello embedded Linux developer,

Embedded Linux Conference Europe 2020 has concluded (it was last week: Oct 26-28).

Please note that all sessions for ELCE 2020, as well as for the "co-located" Open Source
Summit Europe 2020 are available for viewing through the month of November, 2020, at https://www.accelevents.com/e/OSSELCEU2020

There is no charge to access the event and it is freely available to the general public.
This includes all breakout sessions and keynotes. In the session UI, the Chat and Q&A
windows have messages for that session at the event.

Most sessions also have slides available on the individual session pages at:
https://osseu2020.sched.com/

Videos are available at the event site (accelevents) now, and will be put on YouTube within the next few weeks
(likely before the end of November). When they are made available on YouTube, we will add links to
https://elinux.org/ELC_Europe_2020_Presentations (where we are currently gathering presentations
from the event).

I think this is a valuable free resource for the embedded Linux community.

Enjoy!
-- Tim

Hello embedded-interested people,

I just wanted to remind people about Linux Plumbers conference, and
the upcoming election of 5 members to the Linux Foundation
Technical Advisory Board.

I hope people take the opportunity to join Plumbers this year.
With it being virtual, more people than ever will be able to participate.
And this is an interesting and valuable conference.
For registration, follow the links from this page:
https://www.linuxplumbersconf.org/event/7/page/47-attend

If you attend, please consider voting for my friend and colleague
Frank Rowand, for him to join the TAB. Frank's self-nomination
can be found on the tech-board-discuss list here:
https://lists.linuxfoundation.org/pipermail/tech-board-discuss/2020-August/000561.html

I think Frank would make a great addition to the TAB, and represent
and under-served Linux developer constituency.

Regards,
-- Tim

MPPWG was the Mobile Phone Profile Working Group, which I led in an ill-fated effort to define an open API for phones built on Linux,
back before Android swept the field. We did have talks at a couple ELCs.

Overall - Is each item below intended to be a standalone page, or

is the intent that sub-topics will be sections within a top-level page?


Some of the sub-topics (e.g. RealTime) really are big enough to have

their own top-level page (or even several pages).


Maybe this will depend on the number of talks that end up on a page?


> Here is the proposed category list:

> * Linux General

> ** Status Check

I'm not sure what "Status Check" is - can you give an example talk in this category,

or describe it more?


> ** Upstreaming

> ** Community

> ** Development process

Maybe add "Legal" here?


> ** LTSI

LTSI might go better under "distributions"?, but I'm not sure.


> * [[Buildsystems]]

> ** Yocto

> ** Buildroot

> ** Bitbake

There are lots more: OpenWRT, Embedded Debian, Debos, etc.

How would you categorize ELBE, which builds binary distributions from Debian?

Would it go on this page?


> * Scheduler

I'm not sure I see scheduler as a top-level page. I'm not sure how many

scheduler talks we've had. Power-management scheduling was a big

topic for a while (e.g. big.LITTLE), but maybe going back farther there

were lots of talks when the O(1) scheduler was introduced.


> ** Real Time

RealTime is big enough to deserve it's own top-level page.

Likely, Scheduler is not big enough to deserve it's own top-level page.

In fact, RealTime might deserve two pages: one for PREEMPT_RT

and the other for dual-kernel approaches (e.g. Xenomai)

I'm not sure what the "Source code" category is here.

Does "IO scheduling" go here?

Security divides into multiple categories. There are mandatory access control

systems, like SELinux, AppArmor, Smack, Tomoyo. And then there are different

aspects of security like:

** Secure Boot

** Cryptography

** Trusted stores (TPM)

** Hardening


> * Upgrades

> ** OTA updates

> ** Firmware upgrades

> * Legal

OK - maybe this should be a standalone page, but it's kind of in the

non-technical category of pages.

I would put Fuego underneath a sub-category of

** Test Frameworks

*** Fuego, KernelCI, Kselftest,


I would add:

** Board farms and infrastructure

Not sure what "MPPWG" is.

Add ftrace here.

I thought Tomoyo was a security system, not a distro, but I could be wrong.

I'm not sure

Legal could also go here?

This category seems to be "Development Tools", not applications.

I think I'd stick these under "networking", but some are higher-level protocols.


> ** UPnP

> ** Protocols like UDP/TCP/IP/HTTP/SOAP/SSDP/XML/GENA/SCPD, SIP, IM, XMPP

> * Open Source Projects

I don't think that "Open Source Projects" is a good category for these sub-topics:


> ** Zephyr

We should probably have a "non-Linux RTOS" page. I think there have been several

different talks over the years for non-Linux OSes (NuttX, Zephyr, Free RTOS, etc.)


> ** BeagleBone Board

> ** Dragon Board

> ** Nine-Dollar Computer CHIP,

We should have a "Hardware" category for these board-specific talks.

These should be under networking

I think I'd put "Home Automation" as it's own topic (not under IoT)


maybe also add "Embedded Industrial Systems" as a topic?

I'd put Robotics and Drones under verticals.
