I often ran into an issue with CoRD failing to copy/paste between my host machine and my remote desktop machine. This only occured when multiple remote desktop session were active. The clipboard chain gets broken and copy/paste between the host machine and the remote desktop stops working.

To solve this, you need to execute the following batch file on the remote machine:

@echo off
taskkill /IM rdpclip.exe /F
start %SystemRoot%\system32\rdpclip.exe
exit

Open a terminal and execute the following commands:

$ defaults write com.apple.Finder AppleShowAllFiles YES
$ killall -HUP Finder

Reversing this process can be done by:

$ defaults write com.apple.Finder AppleShowAllFiles NO
$ killall -HUP Finder

Related to this blogpost, I wanted to log all queries executed on a Microsoft SQL Server database.

This can easily be done by the SQL Server Profiler, which gets shipped with the SQL Studio Express application of Microsoft.
However, after navigating through my webapplication (which uses JPA (Hibernate)), I could only see a bunch of the following SQL statements:

EXEC sp_execute 6, 8
EXEC sp_execute 7, 8
EXEC sp_execute 4, 8

Hibernate is running a prepared query. To get the actual SQL query, you can run the following query (you will still have to look for the query, but, it's getting you a lot closer then sp_execute :-)):

SELECT        SQLTEXT.text, STATS.last_execution_time
FROM          sys.dm_exec_query_stats STATS
CROSS APPLY   sys.dm_exec_sql_text(STATS.sql_handle) AS SQLTEXT
WHERE         STATS.last_execution_time > GETDATE()-1
ORDER BY      STATS.last_execution_time DESC

By tweaking the WHERE clause, you can easily retrieve the quer(y)(ies) you are looking for :-)!

Yesterday, I came to the conclusion all my cron entries were removed (for the second time!) in my /etc/crontab file on my Synology DS213 NAS server.

I noticed the cron entries were removed after a system reboot. I figured out Synology has some problems with cron entries having columns separated with spaces (not tabs). All entries including spaces are removed on system startup.

Updating my crontab by putting tabs (\t) between the columns, fixed the problem.

MySQL

SELECT STR_TO_DATE('20/03/2013', '%d/%m/%Y')
FROM dual;

Microsoft SQL server

SELECT CONVERT(datetime, '20/03/2013', 103);

On my Windows laptop, I'm using Outlook 2010 to fetch my Gmail account (IMAP). Gmail has its own spam folder + spam filter, and I configured Outlook to use the Gmail spam filter.

Nevertheless, Outlook always creates a second spam folder (in Dutch called: Ongewenste e-mail), which makes it complicated on other clients (or webclient) to know which one is the correct label.
I just learned you can hide labels in your webclient and/or IMAP clients by logging in into Gmail webaccount > Settings > Labels . I also marked some other labels to be hidden as well.

• Go to: Start -> Run -> Type cmd and press enter
• Once the command line is on screen tell SQLCMD to import your database by doing something like this:
  

  sqlcmd -S [server instance name] -d [database name] -i [filename you want to import]

• If you're not sure about the server instance name; simply open up SQL Server Management Studio and on the login screen take a note of the Server Name textbox as this is the value you need to use as the server instance name.
• If you are trying to enter a lot of INSERT statements, don't forget to flush while inserting using the GO command (for example, after each 100 rows).
