bsdphx writes "OpenSSH developers Damien Miller and Markus Friedl have recently added a nifty feature to make life easier for admins. Now you can easily lock an SSH session into a chroot directory, restrict them to a built-in sftp server and apply these settings per user. And it's dead simple to do. If you need to allow semi-trusted people on your computers, then you want this bad!"

Microsoft has released documentation on their Office binary formats. Before jumping up and down gleefully, those working on related open source efforts, such as OpenOffice, might want to take a very close look at Microsoft's Open Specification Promise to see if it seems to cover those working on GPL software; some believe it doesn't. stm2 points us to some good advice from Joel Spolsky to programmers tempted to dig into the spec and create an Excel competitor over a weekend that reads and writes these formats: find an easier way. Joel provides some workarounds that render it possible to make use of these binary files. "[A] normal programmer would conclude that Office's binary file formats: are deliberately obfuscated; are the product of a demented Borg mind; were created by insanely bad programmers; and are impossible to read or create correctly. You'd be wrong on all four counts."
