comment Converting accelerometer reading from Hex to Decimal
@Dilip - Those are shell tools for manipulating text files. They're available on Linux and Mac machines, or through Cygwin. If you want to integrate this process into Matlab, I suggest using the textscan function. However, you could probably do this in a text editor if you wanted to!

You want to remove every other line and remove the first, third, and fifth space in the remaining lines? That's a job for sed, awk, cut, or your favorite scripting language, not a question for an electrical designer. It might be on-topic if you wanted to modify the firmware of your device to generate that information, but that will probably involve just modifying the formatting of a snprintf() statement.

comment Getting Lithium Polymer Battery to forget past?
@Dean - Erm, no, that's not what I was saying, but I suppose that would probably work. Check the capacity ratings (with System Profiler) before and after to see that you were successful. I assumed you were human and had to sleep occasionally, so 5 hours of downtime wouldn't matter. My bad! If you're a robot or cyborg, just run it off a socket until you do have some downtime. Not sure what to do if you're running a server or something from your laptop, though.

comment Getting Lithium Polymer Battery to forget past?
It still works when it's plugged in. It even works on wall power when the battery is removed entirely! You shouldn't have downtime unless it's impossible to access an outlet where you need to work.

comment Does e-mail address obfuscation actually work?
@ijw - The ongoing cost of a team of a few people at Google maintaining the spam filter system will always be less than making their hundreds of millions of customers do anything at all. Assuming that spam is kept to a reasonable amount, the bandwidth probably isn't much of an issue either.

comment Can not create files in own user folder?
Except for the deny add_file, add_subdirectory, delete_child, writeattr, writeextattr, chown part. I just learned about ACLs, thanks to you!

@Jay - It looks like the only user is 'ber'. Are you thinking it might be something different?

This might be better suited for electronics.stackexchange.com (but I can't really tell...)

Speaking of troubles with pipes and buffering, take a look at the update to my question. More work is required...

comment Split an[d] archive large backup file in constant working space
Something like (pseudoscript) tar [opts] | myscript.sh, where myscript.sh is something like for i in size/4.7GB; do \ dd [your opts] of=part.tar."$i" | mkisofs [] | wodim []; rm part.tar.$i; echo "insert new disk"; read; done. I'll turn this into real bash when I get home to my Linux box tonight.

comment Split an[d] archive large backup file in constant working space
dd looks promising, though - I think I'll similarly use the bs, skip, and count options to get a part of the disk, burn the disk, and then delete the part. I was barking up the wrong tree with split.

comment Split an[d] archive large backup file in constant working space
What I'd like to do is to burn DVDs of a big folder, without needing space for all the DVDs at the same time. Looking more closely at your script, it looks like it may not work as well for my application. I start out with a folder, which I'd like to still have when the program is done running. Both my hypothetical method and your method require that I have space for one full part in addition to my current archive, which is fine.
