I finally found a bunch of files to enable theming in the Eclipse IDE like the themes one can find for Textmate or Vim. Here are a bunch of popular themes for syntax coloring. To use these files, download the EPF files, and then import them into Eclipse via File > Import > Preferences… and picking any of the files below to apply the theme.
Installing MySQL gem on Mac OS X Leopard

Installing the MySQL gem on Leopard was much more painful than I thought. I had the 64-bit version of MySQL already installed. So I had to uninstall MySQL on Leopard, which was a challenge all on its own. Here is what I did (after stopping MySQL, and backing up my databases first, of course):
sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* vi /etc/hostconfig # remove the line MYSQLCOM=-YES-
Then I had to install the 32-bit version of MySQL for Mac OS X. After that is installed, I had to use the following to get the gem to compile:
sudo env ARCHFLAGS="-arch i386" gem install mysql -- \ --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \ --with-mysql-include=/usr/local/mysql/include

Configuring Gmail as SMTP Relay on Postfix
52 years ago

Elastix uses Postfix, and getting Postfix configured to use Gmail as a SMTP Relay has been incredibly painful to do. This should not be as difficult as it turned out to be, but here is what I had to do to get things working.
Edit the /etc/postfix/main.cf file
nano /etc/postfix/main.cf
Change these lines to your external domain and the name of your elastix server:
################################ #Ingresado por yb-webadmin mydomain = myrealdomain.gotdns.org myhostname = elastix.myrealdomain.gotdns.org
Change the following line
#relayhost = [an.ip.add.ress]to
relayhost = [smtp.gmail.com]:587
Create a new file /etc/postfix/sasl_passwd and put the following line in it
[smtp.gmail.com]:587 loginname@gmail.com:password
Then run the following command
postmap hash:/etc/postfix/sasl_passwd
Create a directory /etc/postfix/certs. Generate a self-signed certificate as follows
cd /etc/postfix/certs openssl req -new -x509 -keyout cakey.pem -out cacert.pem -days 365 openssl genrsa -out gm.key 1024 openssl req -new -key gm.key -out gm.csr openssl ca -cert cacert.pem -keyfile cakey.pem -out ./gm.pem -infiles gm.csr
If you get an error that says something like
Could not open directory ../../CA/newcerts
then do the following before you run the commands above
mkdir -p ../../CA/newcerts touch ../../CA/index.txt echo "01" > ../../CA/serial
and after you are done, you can remove the above directory using
rm -rf ../../CA
Add the following lines to /etc/postfix/main.cf
smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_use_tls = yes smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = noanonymous smtp_tls_note_starttls_offer = yes tls_random_source = dev:/dev/urandom smtp_tls_scert_verifydepth = 5 smtp_tls_key_file=/etc/postfix/certs/gm.key smtp_tls_cert_file=/etc/postfix/certs/gm.pem smtpd_tls_ask_ccert = yes smtpd_tls_req_ccert =no smtp_tls_enforce_peername = no
And finally run
postfix reload
Check your setup by sending a test email
mail myself@myemail.comAnd check the logs for anything going wrong
tail -f /var/log/maillog
Social Networking in a box
03 years ago
I have been looking for a while for a bunch of social networking functionality to use out of the box – it is ridiculous that you have to build all the same basic things over and over again. I think I found exactly what I was looking for – Community Engine can be used as is, but is designed as a plugin as opposed to as an application. Very nice. One of these days, I might actually try it out. Now this is the kind of stuff that makes it harder to go with Django – community is more vibrant on the Rails side.
