Autocomplete greatly increase the speed at which I can perform tasks on a sever, however, not even autocomplete can compare to the time that the ability to ‘search’ through history with the up and down arrow has saved me.
I really wish I could recall where I got this from, but doing a search on “By default up/down are bound to previous-history” turns up more than just a few results…
# By default up/down are bound to previous-history
# and next-history respectively. The following does the
# same but gives the extra functionality where if you
# type any text (or more accurately, if there is any text
# between the start of the line and the cursor),
# the subset of the history starting with that text
# is searched (like 4dos for e.g.).
# Note to get rid of a line just Ctrl-C
"\e[B": history-search-forward
"\e[A": history-search-backward
Actually, it would be more accurate to say that I am testing the Video JS javascript-based video player.
It should be said that the most painful part of all this was encoding to WebM. I truly have no love for the format, mostly because of all the retarded statements that people make about it being a “free” format. Bull. Maybe there isn’t a patent pool put together by any group for WebM, but that doesn’t mean it’s any less liable to be “illegal” where you live.
Enough ranting for now…
Here goes nothing… or something. We shall see.
In any case, so far webby is pretty freaking awesome.
I’m uncertain if I’m going to bring over all my old posts or not… if I find or write a script to do it the chances of the old posts coming over go way up, but again, we shall see.
This is working for me on Mac OS X 10.6.3 however your results are likely to vary…
(And apologies for the crazy hi-lighting… still working on that)

Extract DTS audio using mkvextract, and downmix to stereo using dcadec
Sometimes ffmpeg has issues downmixing DTS and sometimes this works better… (sometimes nothing works and it’s all a waste)
mkvextract tracks m-cloudy-720p.mkv 2:audio.dts
dcadec -o wav audio.dts > audio2ch.wav
Start encoding
Encode for iPod
