If for some reason you lost your SSH server keys, sshd will fail to start with error:
Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_dsa_key
You can recreate your host keys with these commands:
ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
After recreating the keys, you will probably have to let your clients know as with the change of keys, they'll probably get warnings about it (Linux SSH will not even connect until you kick out the old keys).
Microsoft has a free edition of Microsoft Expression, which has the basic functionality of creating screencasts. This way you can create screencasts, and encode them to WMV (or to Silverlight). The free edition is limited to 10 minutes per clip, but this should be adequate for simple short clips.
Microsoft Expression Encoder can be downloaded from the Expression website: http://www.microsoft.com/expression/try-it/; scroll to the bottom to find it.
It never was easier to get rid of those pesky ads in Windows Live Messenger. Simply download A-patch: http://apatch.org/.
Wine now also has precompiled binaries available. Together with WineBottler (an application to prepare and pack Windows applications for redistribution with Wine), it is available here: http://winebottler.kronenberg.org/.
Wine is an application which allows to run Windows application on linux, BSD or Mac OSX. Rather than full emulation, it acts as a compatibility layer between the application and the OS.
Wine is not entirely foolproof just yet; there is still much to be done, but with each passing release, more and more applications are getting supported.
Adobe has an FTP site available where you can directly download installers and updates of their products, without going through the site, license agreements and download managers.
For PDF reading, the direct links are:
Links to other products will follow. Keep an eye on this post on the site.
