[OSGeo-Discuss] Revisiting the Raspberry Pi -- new developments
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 Quote Thu May 28, 2020 6:29 am [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. https://www.tomshardware.com/how-to/boot-raspberry-pi-4-usb 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. https://www.raspberrypi.org/blog/vc4-and-v3d-opengl-drivers-for-raspberry-pi-an-update/ Ubuntu 19.10 64bit V3D OpenGL driver for Raspberry Pi 4 > Quote > Wed Jan 08, 2020 3:01 pm > Hi, I am using the latest Ubuntu 19.10.1 64bit which contains mesa 19.2 > package. How can I activate the latest v3d video driver in my system to get > graphic acceleration in 3d games and applications? I tried writing > dtoverlay=vc4-fkms-v3d in my /boot/firmware/config.txt, but could not load > the lxqt desktop. Black screen only https://www.raspberrypi.org/forums/viewtopic.php?t=261426 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.

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.
