comment Writing debian iso to usb stick from windows results in 440kb filesystem with 1 file
Thank you! The program Rufus linked from the archlinux page worked for me, but I also realized that there was another issue going on where it would not recognize my flash drive if I left it plugged in through a reboot. I'm not sure if my other attempts would have worked if I removed and re-inserted the flash drive when booting. In any case, I was able to successfully install Debian.

comment Webcam software for streaming and playing that can be configured
I found that most of the delay was due to caching behavior. On the server be sure to manually set "live capture caching" and "stream output muxer caching" and on the client receiving the video be sure to set "network caching" All three are additive and I think the default settings put the latency at two seconds bare minimum just by the amount of buffering done.

Thanks, I'll probably use this, but it still doesn't solve the error correction problem.

That's interesting, unfortunately, this requires a scanner or some other imaging system attached to the computer to work.

No. I made a 28K rar file. Added recovery volumes to it with >50% recovery volumes. Base64 encoded it. Deleted six characters from the contents and added two. Base64 decoded it. rar COULD NOT recover the file. That is completely unacceptable for any sort of use that I've described. I'm not sure what "well enough for most people" is, but if it cannot correct a 0.02% error rate with >50% redundancy, then it certainly is not well enough for me. I don't care if it's something specifically designed for hand transcribing, but yes, my question is what can I use that will work.

See, that's what I have the problem with: "you would have a program to encode the data"...no, I don't. I don't have a program to do this, and I don't know of any program to do this. I am also not aware of any file format that can gracefully handle a byte removed (not erased) from near the beginning of the file on top of other errors. I definitely agree that these are methods for increasing data density, but that's not my primary concern now, it's ease of reading/writing and error protection.

Color blindness is more of a dimensionality reduction of color space than it is a selective inability to see certain colors. I mean, I probably could pull off Black, Blue, Yellow, Red, Green, Gray, but not much more

Obviously I am planning on using upper case characters as well. Out of all the error correction schemes you have suggested, I don't see any way to implement them without designing a custom file format, etc. Is there really no precedent for putting error correcting protection on files? Perhaps I should also have mentioned that creating custom programs is also highly undesired? I can't seem to find any program which will just protect your files with error correcting codes.

Well, there's a few issues with this. 1. I'm colorblind. 2. It requires buying a bunch of pens. 3. It doesn't help at all with the error correction. 4. It involves writings codes instead of text, which humans are worse at.

Hmmm, in fact, I've done a little test with an essay of mine. Original essay: 14,116 bytes =>nanozip compressed: 4,118 bytes => base64 encoded: 5565 bytes. with almost 50% redundancy, we still have cut the number of characters to copy in half. In fact, if you don't like copying characters, but want to copy text instead, stenographically encoding it using fourmilab.ch/javascrypt/stego.html still only increases the size by about a factor of four, so we are left with an essay only twice as big as our original. Pretty good, huh?

Only a single color pen, otherwise transcribing it will be too difficult. I'm actually transmitting compressed, signed, encrypted text, so assuming even a 50% redundancy rate, the total amount of writing will be <1.5 times as much as actually writing out the original text would be (once you take into account the compression). However, there is the issue that copying random characters is harder than copying English text. So to answer your question, certainly only in the couple of kb range.
