How I start programs at boot on my Raspberry Pi. Below is a copy of the /etc/rc.local file I use on my raspberry pi.
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. # Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi ################## Added by MrX 28/12/12, ############################################################ # V1, 21/03/14, titied up script, added explination, run didiwiki and got detached screen working at boot # items are run in a subshell enclosing command in ( and ) # the commands are terminted with a & to run as background task # by default programs are run as root if this is not required "su" is used to switch user to pi # becuse each program is run as a subsheel they all run in parallel this is why the sleep # command is needed, each sleep command must be longer than the sum of the sleeps before # which ensures the commands are run in sequence and not together # exit 0 was from the original file to ensure the file exited with status 0 # if the script doesn't exit with status 0 then the pi will not fully boot # At boot fources audio aoutput to headphones socket (Analogue output) # from magpie magazine pdf, issue 3 page 4 (sleep 1; /usr/bin/amixer cset numid=3 1) & # At boot run the command didiwiki as user pi, listening on IP 192.168.1.13 port 8000 (sleep 3; su pi -c "/usr/bin/didiwiki -l 192.168.1.13 -p 8000") & # run a detached screen session at boot (sleep 6; su pi -c "cd /home/pi ; /usr/bin/screen -dmS pi-debian -c /home/pi/.screenrc.multiwin") & exit 0

These are the places your sdk/ndk/ant goes:
/usr/local/share/android-ndk-r9d /usr/local/share/android-sdk-linux /usr/local/share/ant
This is an archive of /usr/local/share/android-sdk-linux/bin, which is the directory you create.
http://theadesilva.com/hpr_bin.tar.gz
This is what /etc/profile.d/android.sh looks like:
export ANT_HOME=/usr/local/share/ant export JAVA_HOME=/usr/ export PATH=$PATH:/usr/local/share/android-sdk-linux/bin:$ANT_HOME/bin
here's the example app:
http://theadesilva.com/pants.tar.gz
uncompress it and type "make", that produces app.apk to run on your device.
A short explanation of how I personally got involved with accessible computing, a definition of the term 'accessible' as it is applied to anything in relation to persons with physical or cognitive impairment, and very short list of the most commonly used adaptive tools to improve accessibility to Windows and Linux.

Back after a year of HPR silence, I'll talk a little about how I like to spend my lunch breaks and how you can explore your workplace. Put down those tater tots, we're going on an adventure!
In this episode I'll give some information about my lunch history, ways you can maximise your time, gear you'll need to start short stealth/urban exploration, techniques for finding places to explore, and ways to handle being spotted.
If this goes well enough and the audio isn't too garbled, I'll record episodes for the "How I Got Into (GNU) Linux" series.
Here are a few links related to the episode. Note that I link to Amazon and Google. I don't necessarily condone or endorse either service, I just didn't know of any better sources for product information.

We have looked at e-mail encryption on both Thunderbird and G-Mail, and that is good, but in 2014 a lot of people use mobile phones and tablets for their e-mail. So it makes sense to look at how we can do this. The solution I am going explore here involves two components, the K-9 Android mail client, and APG, the Android Privacy Guard. I am going to stick to what I know, so if you are looking for help with iPhone or iPad, the best I can do is suggest that you try a Google search. On Android, while many people use Gmail, K-9 is a very popular client for people looking for a more traditional POP3 or IMAP client to handle their e-mail needs. So this should be a good solution for many people. As regards APG, I am not aware that anyone has done an audit of this program. It seems to be the most widely recommended, and is probably OK, but I am making no larger claims for it. - For more go to http://www.zwilnik.com/?page_id=602

Writing screenplays for TV or movies is a very precise thing. The industry expects a standardised style and format. ThistleWeb explores a couple of dedicated screenplay writing solutions. Both are dedicated applications that do one job and do it very well. The first is Trelby. It's a GPL cross platform application. It has lots of additional features such as auto completion of character names, summaries and stats.
The second application is a cloud service called Raw Scripts. It's a Chrome extension although I think that's just a link to the site. You log in with a Google or Yahoo account. It's like a dedicated Google Docs web app. It does most of the things Trelby does. It also exports to Google if you want. You can share and collaborate with Raw Scripts. It's hosted on their server, although it's AGPL going forward, so it shouldn't be long before you can host it on your own server.
I've just started to explore screenplay writing as a writing skillset. Both of these applications make the styling and formating incredibly easy, allowing me to concentrate on the actual story.

In creating a chart or graph you have a number of options that can make your chart easier to read and understand. In this episode we look at these options and explain what each of them does.
SPECIAL ANNOUNCEMENT HPR_AudioBookClub SNEAK PREVIEW!!! Sometime in the not-too-distant future we'll be reviewing Street Candles by HPR's very own David Collins Rivera (aka Lostinbronx). Street Candles is not finished yet, but is available via RSS and Lostinbronx publishes a new episode each week. This book is excellent, and you'll want to say you were there to see it happen. Head over to LNB's site for all the details http://www.cavalcadeaudio.com/ and remember to subscribe to his RSS feed:
In this episode, the HPR_AudioBookClub reviews The Crown Conspiracy by Michael J. Sullivan. This book received thumbs up from all of this month's participants. You can download this audiobook for free (or voluntary donation) from http://podiobooks.com/title/the-crown-conspiracy/ and it's also available in paperback on Amazon: http://www.amazon.com/Crown-Conspiracy-Michael-J-Sullivan/dp/0980003431 . You can find more content (including podcasts) from Michael J. Sullivan http://riyria.blogspot.com/ Many of his books are also available in paper and ebook editions on amazon.com.
As usual, during this episode of the AudioBookClub the hosts have each reviewed a beverage of their choice. Morgellon drank a Bourbon and soda, but not during the show because he was driving. He recommends both Woodford Reserve http://www.woodfordreserve.com/ and Evan Williams Bourbons http://www.evanwilliams.com/ x1101 drank Wild Turkey 101 proof Bourbon http://wildturkeybourbon.com/ pokey drank a cup of Oolong tea. It was probably a little stale, but pokey is a knuckle dragger, so he didn't notice at all. http://www.foojoyteas.com/teabag.php . This was the first time that pokey has reviewed an NA beverage for the AudioBookClub, so we apologize if the show has suffered because of it. Thaj won the Non-Alcoholic division hands down with a glass of fresh squeezed lemonade. Colin couldn't make it to this recording because of time zone differences, but he did write in. I'll add his note to the episode comments. Please add your own comment as well. His beverage however was an Innis and Gunn Original http://www.innisandgunn.com/the-range/core-range/original/ to which he gives his thumb up.
Our next audiobook will be How to Succeed in Evil: The Novel by Patrick E. McLean http://podiobooks.com/title/how-to-succeed-in-evil-the-novel/ (not to be confused with How To Succeed in Evil: The Original Podcast Episodes by Patrick E. McLean) This book was suggested by Morgellon. Our next book club recording will be 2014/06/10T23:00:00+00:00 (https://en.wikipedia.org/wiki/ISO_8601#Times)
