Due to this complexity aspect, post-mortem analysis of such failure is quite often problematic, sometimes even impossible due to the lack of enough data. To mitigate this problem and simplify identification of the failure root cause, it would be nice if it might be possible to continuously monitor electronic systems in the car, providing for possibili… text/html 2021-04-17T12:13:44+0200 Anonymous (anonymous@undisclosed.example.com) http://www.tio.cz/doku.php?id=projects:garmin&rev=1618654424&do=diff Monkey C syntax highlight in vim $ cd ~/projects/garmin/ $ git clone https://github.com/klimeryk/vim-monkey-c.git $ mkdir -p ~/.vim/syntax ~/.vim/ftdetect $ cp ~/projects/garmin/vim-monkey-c/ftdetect/monkey-c.vim ~/.vim/ftdetect/ $ cp ~/projects/garmin/vim-monkey-c/syntax/monkey-c.vim ~/.vim/syntax/ text/html 2021-05-17T13:31:05+0200 Anonymous (anonymous@undisclosed.example.com) http://www.tio.cz/doku.php?id=projects:iot&rev=1621251065&do=diff Internet of Things IoT SW platforms * ThingSpeak * ThingsBoard - Open-source IoT platform Source of Information * Article Jak na IRQF on Root text/html 2013-02-02T11:20:57+0200 Anonymous (anonymous@undisclosed.example.com) http://www.tio.cz/doku.php?id=projects:linux_on_ipaq_hx4700&rev=1359800457&do=diff Linux on iPAQ hx4700 Building Ångström on Mageia 1 Install necessary packages * git version control system $ sudo urpmi git * Python ply - lex and yacc parsing tools for Python $ cd ~/Downloads $ wget http://www.dabeaz.com/ply/ply-3.4.tar.gz $ tar xvzpf ./ply-3.4.tar.gz $ sudo rsync -av ./ply-3.4/ply /usr/lib/python2.7/site-packages/ $ rm -fr ./ply-3.4 text/html 2013-02-02T11:20:56+0200 Anonymous (anonymous@undisclosed.example.com) http://www.tio.cz/doku.php?id=projects:obdii_data_logger&rev=1359800456&do=diff OBDII data logger KWP2000 Lower Layer KWP2000 Upper Layer Couple of measurements [KWP2000 Fast Initialization] [P3] [P4] [RT Duty Cycle] text/html 2019-12-25T16:34:56+0200 Anonymous (anonymous@undisclosed.example.com) http://www.tio.cz/doku.php?id=projects:openssh&rev=1577288096&do=diff scp 1) scp run on client (copy remote to local case) * construct scp command to be executed on the server via ssh. append -v -r -p -d flags as appropriate.
