Land Pattern Design
"Open Symbol Project" with Mark Whitis - “The Open Symbol Project aims to create an open collection of schematic symbols and PCB footprints released under a license that does not interfere with use in either commercial or free projects.”
PCB Matrix has two tools that are useful for creating land patterns for SMT components (Windows only)
Notepad++ - Awesome text editor for Windows. Similar to TextWrangler on OSX.
Acronis True Image - The best backup tool I have found for the PC (so far). Good but not great IMHO. My main justification for using it is that I got it for a deep discount, around $30.
I was spoiled by Time Machine on the Mac and I haven't found anything nearly as good for the PC. What I liked about Time Machine: allows full disk recovery to last restore point, continuous incremental backup, intelligent management of backups to conserve disk space. If anything like this exists for Windows 7, please let me know. — jeff 01/11/2011 01:19
