[GTALUG] GameShell: The Hackable Handheld Retro Gaming System

2017-11-14 Thread Scott Elcomb via talk 
Thought this might be of interest to some on the list.

"GameShell is the world's first modular, portable game console with a
GNU/LINUX embedded operating system. It allows you to play thousands
of classic games from Atari, GB, GBA, NES, SNES and many of history’s
greatest consoles."

It has a modular gameboy-like form factor based on Clockwork Pi (Quad
Core A7), 512MB RAM and a 2.7in RGB display.  The expected delivery
date is in April 2018.  The Super Early Bird price is $89.00 (+ $10.00
for shipping to Canada) which is about $50 less than the expected
retail price.

Re: [GTALUG] BASH on Android OS

Consider this another vote for Termux.  I have not tried starting
anything on boot but termux-boot looks like what you'll want

 via



"When developing (or packaging), note that this app needs to be signed
with the same key as the main Termux app in order to have the
permission to execute scripts."

I'm not sure about how to handle the signing (perhaps you'll need to
build your own copy of Termux) - may be worth asking via

Going out on a limb I'm going to guess it's this one... First result

It may have been a Cygwin instance, but tbh I just don't recall in
which environment I first encountered the issue.

In my day-to-day tasks, I spend lots of time in mixed environments,
managing systems with components that run across Linux, OSX and
Windows.  Additionally, there's a fair amount of time playing &
learning in other operating systems (BSD's, Plan 9, hobbyist OS's,
etc) as well.

Basically this; I've been bitten a couple times with a missing
/bin/bash (though never /bin/sh)

Picked the trick up a few years ago (not sure where) and never looked back.  :-)

Here's a quick and dirty bash script similar to the watch command;
adjust to taste. :-)

[- watchdir.sh snippet starts -]

#!/usr/bin/env bash
#
# USAGE
# watchdir.sh  
#


# Determine our sampling rate
WATCHRATE=${1}

if [[ "" = "${WATCHRATE}" ]]; then
WATCHRATE=10
fi

# Determine our watch directory
WATCHDIR=${2}

if [[ "" = "${WATCHDIR}" ]]; then
WATCHDIR="."
fi

# Describe what we're doing
echo "Watching ${WATCHDIR} every ${WATCHRATE}s:"

# Render a side-by-side comparison with last snapshot of our directory
# note: assumes at least one snapshot already exists
function sample_watchdir {
cp .current .previous
date > .current
ls -l ${WATCHDIR} >> .current
echo ""
diff -y .current .previous
}

# Begin watching
date > .current
ls -l ${WATCHDIR} >> .current
sample_watchdir

# Every WATCHRATE seconds, make the current file listing our previous
#   listing, take a fresh look at WATCHDIR and compare the changes
while sleep ${WATCHRATE}; do
sample_watchdir
done

[- watchdir.sh snippet ends -]

It'd be interesting to see what an open monitoring network might
reveal.  Here's a Raspberry Pi - Stingray Detector that uses a
Raspberry Pi along with a SIM 900 module to monitor local cell towers:

Scott's cases were the best when I picked up my first pi's, still
using a couple around the house.  Here's one playing dev server:


I've not grabbed any Pi 3's yet but do have a 2 - and successfully ran
some WebGL test scenes exported from Unity 3D. Great little machines.
