Summary:

Several short presentations about the Raspberry Pi 4 and other SBCs

Abstract:

Several short talks by Brian, Federico, and Bob.

Brian DeLacey discusses and demos the latest Raspberry Pi 4 developments
and news about IPFS. Demos will cover power saving RPi firmware updates,
a recent Raspbian release, and using the RPi as a "dual HDMI daily
driver". Now the RPi4 is an even "cooler board", and we'll try to solve
the mystery of leaking radio frequency. We'll also discuss how to use
IPFS and RPi to "pin down" the latest developments on the distributed
web. This is DeLacey's fourth in an ongoing series of short talks about
the RPi.

New IoT Hardware: Federico Lucifredi will review the capabilities of the
brand new 64-bit SheevaPlug that just landed in his lab.


Bios:
Federico Lucifredi is The Ceph Storage Product Management Director at
Red Hat, formerly the Ubuntu Server PM at Canonical, and the Linux
"Systems Management Czar" at SUSE.
Bob is probably best known as co-creator of the original spreadsheet
application, VisiCalc. His detailed bio is at

Parking:
On-Campus Free Parking (These parking lots are free after 5pm)

The Amherst Street/E51 parking lot is the best parking option. It
probably will have plenty of spaces. During the school year the lot
tends to be full, but tends to clear out after 6:30 or 7PM.


Due to the never-ending construction, Sloan's Hermann Garage is only
accessible via Main Street. It is a small garage without a gate, and
directly under the Sloan library.

All other MIT lots require permits after hours.

The closest public parking
is Kendall Center Green Garage, next to the Marriott Hotel. The entrance is
90 Broadway Street. For other parking options, see
http://web.mit.edu/facilities/transportation/parking/visitors/public_parking.html


All Cambridge parking meters use Passport by Phone:
https://www.cambridgema.gov/traffic/Parking/paybyphone
This is active on all Cambridge metered parking spaces. Meters are free
after 8PM

Boston Linux Meeting reminder tomorrow, Wednesday, December 18, 2019 - MIT App Inventor

When: December 18, 2019 7:00PM (6:30PM for Q&A)
Topic:  MIT App Inventor
Moderator:  Jeff Schiller
Location: MIT Building E-51, Room 315

Note: Parking at E-51 is now free. See note below

Please note that Wadsworth St is open from Memorial Drive to Amherst St,
but is closed between Amherst St to Main St. See the ling below for
additional details.
https://courbanize.com/projects/mit-kendall-square/updates

Summary:

An intuitive, visual programming environment for building smartphone and
tablet apps

Abstract:

Those new to MIT App Inventor can have a simple first app up and running
in less than 30 minutes. The MIT App Inventor project seeks to
democratize software development by empowering all people, especially
young people, to move from technology consumption to technology creation.

Jeffrey discusses the back end of MIT App Inventor, including how he
migrated an instance with 200,000 users and 100 GB of storage from one
cloud provider to another with only a few minutes of downtime.

Bio

Jeff works at MIT in the Information Services and Technology Department
(IS&T). For more then 20 years he's managed MIT's Internet presence. He
also built a significant portion of MIT's Security Infrastructure
including its X.509 certificate deployment. MIT is probably has one of
the largest deployments (and certainly the oldest, dating back to 1996)
of X.509 client Certificates.

Boston Linux and Unix InstallFest LXXI reminder, tomorrow, Saturday December 7, 2019

Boston Linux and Unix  Installfest LXXI
When: Saturday December 7, 2019, from 9:00 am to 5:00 pm
Where: MIT Building E-51, Room 061
2 Amherst St, Cambridge
http://mitiq.mit.edu/mitiq/directions_%20parkinge51.htm
Parking is free at the E-51 lot in front of the building.

Lunch is generously sponsored by Ron Thibeau owner of Bluefin Technical
Services

What you need to bring: Your computer, monitor, power strips and your
Linux distributions. We do have copies of some distributions.
In general we have expertise with most distros, but if you need special
expertise, please email the BLU discussion list in advance. Today, most
distros are using Live images that you can try out and then install.
This can be copied to DVDs or USB sticks.There are a number of USB
creators, such as UNetbootin (https://unetbootin.github.io/). Both
Fedora and Ubuntu have a USB creator built in.

COST: It's free! However, we DO have expenses, and contributions are
welcome. Please consider contributing $25 per machine.

Our volunteers will help you to install Linux on your own system. While
Linux runs on most systems, some systems do have configurations and
hardware that may not be supported. Please consult the following web
pages for hardware compatibility. While we prefer you to bring your own
distros, our volunteers will normally have

        Linux Howto Pages: http://tldp.org/HOWTO/HOWTO-INDEX/howtos.html
        Linux Frequently Asked Questions: http://tldp.org/docs.html#faq
         Additionally, there are forums and listservs for most distros.

Generally our volunteers have sets of the latest Fedora, SuSE and Ubuntu
distributions:
        * Fedora - https://getfedora.org/ (Fedora 31 Live DVD/USB)
        * Ubuntu - http://www.ubuntu.com ( 18.04.1 LTS DVD/USB or 19.10)
        * other distros can easily be downloaded at the Installfest

We generally have them on local drives and can burn CDs/DVDs and
USBs.Since there are many variants of these distros, we advise you to
bring an empty USB stick with sufficient memory to hold one of the
distros. Live images require about 1.5GB. I usually have some USBs
prepared or can easily burn a USB.

We usually have both a Wired and Wireless network available.
The preferred wireless SSID at MIT is "MIT". In addition John does set
up a local wifi.


Additionally, you can run Linux on your Windows PC through a virtual
machine manager, such as Virtualbox. You can install this in your
Windows machine and run Linux as a guest OS, or install it in your Linux
machine and run Windows as a guest. Linux has a built-in virtual memory
system, but you can also download and install VirtualBox 6.0
(http://www.virtualbox.org) which is free and is available for Linux,
Windows 10, Windows 8, Windows 7, Windows XP and Windows Vista.
Additionally, there are also some VMWare clients that are also free for
Windows.

Please refer to the BLU website (http://www.blu.org) for further
information and directions. There is a parking lot in front of the
building on Amherst St. Enter the building, and take the elevator your
left down to the basement. Room 016 is directly across from the elevator.
