andLinux “Cannot open display” problems…
make it short:
-> open windows firewall, tcp port 6000
-> adjust the Xming startup command, include a full path for the logfile, e.g. “C:\Temp\Xming.log” instead of a filename only
my 2 cents

Monitor All SQL Queries in MySQL is a very nice (though short) posting about how to debug and monitor what’s going on inside your DBMS. There’s supposed to exist a similar tool for MSSQL called “Profiler”.
found it somewhere in ubuntuforums.org:
echo -n 'file:///path/to/file/name.jpg' | md5sum |
aptitude has a specific list-category to display those when using the curses-GUI, but I do not like it. fortunately, you can use the search-command from the cli-interface with the appropriate search-pattern:
aptitude search "?obsolete" |
or as a shorthand:
aptitude search "~o" |
See the aptitude Reference Guide for more information.
add the following lines (or adjust if already there) in your thunderbird-profile’s “prefs.js”
user_pref("calendar.debug.log", true);
user_pref("calendar.debug.log.verbose", true);

At work, we’re running a 2008R2 AD forest containing 5 sub-domains. now to query the LDAP can be a pity if you don’t know in which one of the overall 6 domains the queried object is located.
After months of helplessness and various (unsuccessful) experiments with meta-directories, ldap-proxies etc. we discovered that the problem is already solved. the solution is to use a different port, ActiveDirectory provides the so-called “global catalog” (containing all the information from the whole forest) on port 3268.
Assume, your username is “un321” and your account is located in the “it” subdomain of the “ads.forest.private” domain. To query for a user called “ab123” use the following ldapsearch-command:
ldapsearch -x -b "dc=ads,dc=forest,dc=private" -D 'un321@it.ads.forest.private' \\ -h ads.forest.private -p 3268 -W "(userPrincipalName=ab123*)" |
to restore a dump from a MySQL database created on a debianish Linux system, just feed the dumped SQL to the command-line mysql client like this:
mysql -u root -p < mysql-all-2010-03-28-0515.sql |
since the whole content of all MySQL databases are overwritten with that stored in the dump, credentials are affected as well. that’s the reason why debian’s system tools won’t work any more after restoring the old dump, since debian creates a maintenance-user called “debian-sys-maint” during the installation and stores the randomly generated credentials in “/etc/mysql/debian.cnf” so it’s sufficient to just copy the “password” values from the old file into the new one and restart mysql. otherwise, you will run into an error like this:
/etc/mysql/debian-start[3181]: Running 'mysqlcheck'... /etc/mysql/debian-start[3181]: /usr/bin/mysqlcheck: Got error: 1045: Access denied for user 'debian-sys-maint'@'localhost' (using password: YES) when trying to connect /etc/mysql/debian-start[3181]: FATAL ERROR: Upgrade failed |
