Just used these instructions on a new 2014-R1 img that failed to resize on reboot and they worked great. Thanks.

Re: Using 'cat' with 'mail'

Don't worry about the quotes. I'm the exact opposite. I don't use them unless absolutely positively necessary. Wimble's right, in this case they aren't an issue.

Re: Using 'cat' with 'mail'

Regarding:

Code: Select all

    cat "/etc/passwd" | mail -s "Subject" someone@gmail.com
The 'cat' command is incorrect. remove the double quotes. cat is expecting a filename.

Code: Select all

    mail -s "Subject" someone@gmail.com < "/home/pi/some_file.txt"
Remove the quotes on the redirect also.

Re: I am at my wits end

"If you use a 3.5" display with the pi you're gonna have a bad time"

Not by a long shot. I have a 'rearview' car display which looks suspiciously like the one he has and it works quite well. I don't watch videos on it but command line is great and if you tweak the resolutions the gui is usable also.

Penn-mush is available for Raspbian. I've installed it it and works.

TinyFugue (tf) the client and tinyMUX the server are also available.

None of these is written in or scripted with python.

Re: Eye-tracker + Raspberry Pi

A glance at the FAQ in question reveals it runs only on Windows USB 3.0 and later on OS X. The RPi has USB 2.0 and since the faq states the device is 'optimized' for 3.0 you should expect some problems. But without the drivers and an api from theeyetribe it would turn into a reverse engineering prob...

Re: Running omxplayer inside X11??

Well, the current source on github doesn't have a -b option. But I believe the answer is that omxplayer writes directly to the screen/frame buffer using the openmax api in the gpu, bypassing X. I'm unclear about overscan handling in openmax. So to get rid of the underlying cruft, yes you have to bla...

Excuse me, I mis-spoke. It is not an image. it is not moved to the SD card with dd or its Window's equivalent. It is a directory tree and is moved to the SD card with sync (or its equiv.).

If you just want to capture the network packets 'tcpdump' is the tool.

But definitely try rebooting it without doing that first and see what hap...

Re: Changing terminal colors

The man page on raspbian is slightly more helpful, showing a table mapping the escape codes to default colors. The kernel keeps a table of colors used by the virtual terminal. There are 15 to choose from and they correspond to the 'white, black, red, ...cyan' etc colors that can be displayed. Each o...

Re: Q: How to split a h.264 video file on the pi?

James,
Would the clips be continuous with no frame drops between clips? If so I could see making extremely large videos by chunking and sending them off the Pi in the background.

But even with a few seconds of drop this would be a very useful feature.

Thanks for the clarification. It appears to me you are using the RPi as a backup appliance. That script should run your rsyncs and immediately shutdown whenever the RPi boots between 3am and 6am.
