can''t get rails to connect to mySQL - HELP!!!!!!!!!
Sorry, but this is really NOT as easy as the tutorials/books make out. I''m really struggling at the first hurdle here. And while I''m not a programmer by design I do know my way around most stuff. And if I can''t get this to work I suspect more people will have the same issues. There seems to be too many variables to address. I have winXP, I have ruby and rails all

rsync many small files
At our lab we have storage with many small files. For example a directory can contain over 15,000 files and each file averages about 75k. I would like to sync this to another filesystem on a different server but I am not sure if there is a rsync tuning flag I can use for such a intensive job. I am using rsync 3.0.3. Also, I would like to use little memory as possible. Any thoughts? TIA

Python/sqlite date time problems.
Bear with me, this is CentOS related. :) I have a python CGI that's behaving weirldy on Whitebox systems that've been switched over to CentOS 4 (ages ago, no other problems to speak of aside from this one). I've broken the problem down to a minimal test case... 1. Create a small database # sqlite3 /tmp/testcase.db 'CREATE TABLE testtable ( date date primary key unique, name

[supermin PATCH] rpm: check for SQLite-based RPM DB
Fedora 33 switched the DB of RPM to SQLite, so no more Packages/Name/etc files.
