[OSGeo-Discuss] Revisiting the Raspberry Pi -- new developments

2020-06-12 Thread Jim Callahan
Back in mid-2012 there was some discussion about whether a Raspberry Pi
could be used for OSGeo Live. Thanks  to Moore's Law, Broadcom and the
Raspberry Pi foundation (and Canonical) there has been some progress in the
eight years since the discussion in 2012; so it may be time to revisit the
issue.

Hello all,
> I've been asked whether OSGeo-Live would run on Raspberry Pi, to be used
> as a teaching device. A Raspberry Pi is a $25 credit card size computer.
> It runs Debian and only has 256 Meg of RAM. http://www.raspberrypi.org
> I've CCed the OSGeo-Live email list, as I expect there will be many on
> the list with an interest, and probably a few opinions too.
> The challenge will be the size of RAM. Up to version 5.0, we ran
> OSGeo-Live with 512 Meg of RAM, but with version 5.5 we discovered that
> some of the Java applications required more RAM, and we recommend at
> least 768 Meg RAM, and preferably 1 Gig.
> The problem will be all the java based applications, which are RAM
> intensive.


1. RAM -- The Raspberry Pi 4 has  a choice of 2, 4 or 8 GB of RAM
https://www.raspberrypi.org/products/raspberry-pi-4-model-b/

2. 64 bit -- Historically, Raspbian OS, the default operating system for
the Raspberry PI has been 32 bit. Recently, the Raspberry Pi Foundation has
announced a 64 bit version to be known as "Raspberry Pi OS".

"Raspberry Pi OS (64 bit) beta test version

[b]This is a beta test of the Raspberry Pi OS (64 bit)[/b]

We still recommend the 32 bit operating system for all Pis at this time,
although have decided it is now time to begin the move toward a 64bit OS.
For the moment this is a 'beta' program, the OS is in heavy flux and its
functionality is likely to change significantly over the next few months.

Note, the 64bit OS is only install-able on the Pi 3 and Pi 4 devices"
https://www.raspberrypi.org/forums/viewtopic.php?t=275370

4. Lubuntu -- OSGeo Live is built on the Lubuntu flavor of Ubuntu. Both
Raspberry Pi OS and Ubuntu are downstream of  Debian, so in effect they
are cousins (not direct descendents of each other). Ubuntu Server has been
ported to the Raspberry  Pi and Step #5 of installing Ubuntu Server is
"selecting a desktop" and fortunately  Lubuntu is one of the choices!

sudo apt install lubuntu-desktop

https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-pi#5-install-a-desktop


5. Disk storage space -- By default, the Raspberry PI 3 and 4 use micro SD
cards. SD cards can easily  hold 32 GB and newer standards allow multiple
terabytes. In addition, a USB 3 port can be used to add an external drive.

By default, Raspberry Pi boots up and stores all of its programs on a
> microSD memory card, which has a maximum theoretical bandwidth of 50 MBps
> on the Raspberry Pi 4 and just 25 MBps on prior models. Using an external
> SSD as your main storage drive could speed things up significantly, but up
> until just recently, you couldn't boot the Pi 4 off a USB device. However,
> new beta-level firmware lets you do just that.
>
> In our real-life tests of a Raspberry Pi 4 with SSD last year we got
> impressive performance with sequential transfer rates as high as 140 MB /
> 208 MBps for reading and writing. You can also use a standard USB flash
> drive, though we found the performance worse than a microSD card on many
> tasks.

 6. OpenGL -- the Broadcom hardware supports OpenGL,  but it is not
implemented on all operating systems.

The GPU bundled with Raspberry Pi 4 is a VideoCore VI capable of OpenGL ES
> 3.2, a significant step above the VideoCore IV present in Raspberry Pi 3
> which could only do OpenGL ES 2.0. Despite the fact that both GPU models
> belong in Broadcom’s VideoCore family, they have quite significant
> architectural differences, so we also have two separate OpenGL driver
> implementations. Unfortunately, as you may have guessed, this also means
> that driver work on one GPU won’t be directly useful for the other, and
> that any new feature development that we do for the Raspberry Pi 4 driver
> stack won’t naturally transport to Raspberry Pi 3.

 Ubuntu 19.10 64bit V3D OpenGL driver for Raspberry Pi 4

So, a number of technological factors are converging to make a Raspberry Pi
4 version of OSGeo Live possible either  on Ubuntu Server/Lubuntu desktop
20.04 LTS or if not by the 20.10 version sometime after October 2020.

So, if it might be possible,

Hello Victoria and the whole OSGeo GCI team,

thanks a lot for sharing this information.

Sad to hear that there will be not GCI in the future.

It os so impressive to see your numbers about only 3 year that OSGeo
participated - 898 students and 2096 completed tasks. Wow. Amazing.

Thanks a lot to the OSGeo GCI Admins team and all mentors, people and
projects involved in GCI. GCI was a great way to get young people
introduced and involved in Open Source Software and bring people from
all over the world together and inspire to collaborate. Thanks a lot.

Good day

The 2019 OSGeo GCI Admin team thought we would share this with you.
The 2019 edition of GCI was the last, the Google Open Source group
will now GSoC and Summer of Docs.

OSGeo participated in GCI for 3 years! Over the three years, we worked
with 898 students that completed 2096 tasks across various OSGeo
projects. Thank you to those of you that served as mentors or answered
questions from GCI students. Thank you!

Hi GCI Mentors and Org Admins,


Google Code-in concluded 10 amazing, productive, exhilarating years in
January. This program has been a success because of the amazing energy
and passion all of you have exhibited; volunteering dozens, hundreds,
and in some cases, thousands(!) of hours to help 14,700+ teenagers,
from 115+ countries, complete a whopping 76,200+ open source tasks,
during the past 10 years!


We wanted all of you to be among the first to know that Google Code-in
2019 was our final Google Code-in contest. We've been looking hard at
our portfolio of programs and as open source evolves, our programs
need to evolve too. We've decided to focus our efforts on Google
Summer of Code and programs like Season of Docs that meet projects'
sustainability needs going into the next 10 years of open source.


We want to thank you all for being inspiring role models to these
students. Many of you were GCI or GSoC students yourselves and have
been paying it forward for years by helping teenagers discover their
passion for open source software development. The extent of your
support was something many didn’t expect when they first started out
trying to complete a few tasks to earn a Google T-shirt.


You have welcomed students into your communities and shown them how
open source is making the world a better place and how they can be a
part of that. You all have inspired, taught, listened, and made a
difference in the lives of thousands of students. THANK YOU! These
students have brought fresh new perspectives and ideas into your
communities, inspiring long-term committers with their enthusiasm,
curiosity and skills.


Many of you have been mentors for all 10 years of GCI (plus GHOP!),
while others came into the GCI family just this past year. Regardless
of when you joined, thank you all for showing immense kindness,
patience, dedication, organization and guidance to the students, the
other mentors in our GCI community, and to me and the rest of our team
over the years.


These past 10 years of Google Code-in have been an exciting,
adrenaline pumping adventure – thanks for coming along on the ride
with us!


We will continue to be dedicated to helping open source communities be
sustainable and finding new contributors is an essential part of those
efforts. While Google Code-in is now officially retired, we look
forward to finding new ways to support your communities.


Best,

Stephanie Taylor

GCI Program Lead
