I have just recently started working on a Mac again and am in the process of getting it set up to do some development.
First thing was to tweak my Terminal preferences and I found a really good article about Mac fonts for programming (Top 10 Programming Fonts). I agreed with the author of that post and went with Inconsolata.→ Continue reading “Very Cool Free Mac OSX Font for Terminal Windows and Programming”
Eclipse (at least Juno) will complain that there is “No grammar constraints (DTD or XML Schema) referenced in the document.”, even though there is no DTD for Ant build.xml files (see here for Ant faq about DTD for build.xml files).
To surpress the warning in Eclipse add
<!DOCTYPE project>
After the <?xml . . . XML declaration tag → Continue reading “How To Disable the DTD Warning for Ant build.xml Files in Eclipse”

To specify the proxy information for svn edit the servers file in the .subversion directory under Linux, or the Subversion directory under the user’s directory in Windows.
Add the following under the [global] section:
http-proxy-host = someurl.com
http-proxy-port = 80
http-proxy-username = uid
http-proxy-password = passwd
http-compression = no

Following is a quick howto for installing the NoMachine free version of NXServer:
. Make sure that you have a DNS entry for the hostname of your NX Server machine or an entry in the server’s /etc/hosts file that points to it’s IP.
. rpm -i nxclient-3.5.0-7.x86_64.rpm
. rpm -i nxnode-3.5.0-7.x86_64.rpm
. rpm -i nxserver-3.5.0-9.x86_64.rpm
. copy stock config file to server.cfg:
. # cd /usr/NX/etc
. # cp server.cfg server.cfg_oem
. # cp server-redhat.cfg.sample server.cfg
. edit config files:→ Continue reading “How To Install NoMachine’s NX Server and NX Client”
I am setting up a vm running CentOS 6.2 and want to be able to connect to it via NXClient.
After doing the basic install and getting the key from the server I got the following error when trying to login on the client side:
Server configuration error. Cannot log in. Please contact your system administrator
Looking at /var/log/messages on the server revealed the following (hostName is the name of the host for the machine, changed from the actual → Continue reading “Solution for ‘Server configuration error. Cannot log in. Please contact your system administrator’ for NXServer/NXClient Session”
If you need to get a Windows command prompt as the Administrator do the following:

The following is a quick howto for when you want to fire up a process as a non-root user on boot under Linux:
Create a script, typically under /usr/bin with something similar to the following:
#!/bin/bash
# invoke your process
/usr/local/process/someprocess
exit
Now, add an entry to /etc/rc.d/rc.local to invoke the command as the non-root user
su – [non-root-user] -c [path-to-shell-script]
Make sure that the exit command is the last thing in the shell script so that you will exit → Continue reading “Starting a Process as a Non Root User on Startup under Linux”
When developing JavaEE applications in Eclipse it is more or less necessary to have all of the JavaEE libraries on the build path.
To do so, do the following:
