For those too lazy to subscribe to TED’s blog 
here are 3 good videos from this year’s TED conference that has recently finished:
- Music that is the source of lots of proud mummy / daddy moments, I expect.
- Economics and science that are funny then at least slightly scary
- Useful wisdom for people in management or education (including parents)
A one-liner to keep your “hi-res” TED feed full:
wget -O- http://feeds.feedburner.com/tedblog 2>/dev/null | sed -ne ‘s/.*embed\/\(.*\)-embed_high\.flv.*/\1/p’ | xargs -i wget -c “http://video.ted.com/talks/podcast/{}_480.mp4″
(Should really add fu to detect when a file hasn’t been downloaded, either fully or at all, and not bother TED’s servers if it hasn’t been.)
wget doesn’t give good return values, but this should do the trick:
wget -O- http://feeds.feedburner.com/tedblog 2>/dev/null | sed -ne ‘s#.*embed\/\(.*\)-embed_high\.flv.*#\1_480.mp4#p’ | xargs -i bash -c “echo looking for {}; if [ \! -e {} -o -e .{}.incomplete ]; then touch .{}.incomplete; wget -c “http://video.ted.com/talks/podcast/{}” | grep saved && rm .{}.incomplete; fi”
