... Unlike clients such as Shout and IceDJ this permits the broadcast of live audio, rather than prerecorded mp3's. LiveIce was developed after the appearance of IceCast to provide the Real Time streaming functionality which makes it a viable solution for broadcasting.

TITLE: New Math (Tom Leahra) (The visual aids) 342 -273 ---- You can't take three from two, two is less than three, so you look at the four in the tens place. Now that's really four tens, so you make it three tens, regroup, and you change the ten to ten ones and you add 'em to the two and get twelve, so you take away three, that's nine. ... And so you have thirteen tens and you take away seven and that leaves five. ... Now the book that I got this problem out of wants you to do it in base eight. ...

... Re : Need easy way to download whole KHG . ... For now, you can use web mirroring packages to create your own local mirror and read from there. Several such packages are available, and since I don't use any of them, I don't have details like names: can someone else who knows please post details? For the future, it would be nice if someone is interested enough in mirroring to write scripts for the KHG that allow you to read it off-line, but also allow you to respond. ...
