10 THINGS WORTH SEEING TODAY

Today's ten lean small, standing in for something much heavier: a player that brings dead Flash files back in a browser, a 3D editor that opens at a URL instead of an install, a text editor that opens a multi-gigabyte file at once, dictation that arrives on one key. The rest are what you keep beside an agent — references before it draws a screen, and a matrix to check what it answers — plus a scanner and a school system you host yourself. Licences and limits are stated as they are.
