Communication using HTTPService over SSL

1. Host the flex 4 application on an SSL enabled host
2. Ensure the application is loaded over SSL (i.e. the URL has https:// prefix)
3. Make HTTPService.url a relative path to where the SWF is stored

Using SSL for mx:Image

Set the Image.source attribute to the full URL, including the https:// prefix, like so:

<mx:Image source="https://server.com/image.jpg"/>

For introductory material on GLSL, check out Lighthouse 3D (where I got this cartoon example). Also check out the orange book for more in-depth discussion and examples on shaders.

$ gtar -g /backup/tar-incremental.log -cjvf /backup/backup.tar.bz2 /etc /usr/local/etc/ /usr/www

The tar-incremental.log file must be saved as it contains information for the incremental backup. Every time you run this file a new file will be created, so do not over-write your files. A more in-depth discussion can be found on the GNU tar incremental backup page.

I let NetworkManager generate my /etc/resolv.conf file. I then copied it to /etc/resolv.conf.head. Once this was done, the server section in /etc/pdnsd.conf was edited to contain the following:

server {
label= "comcast;
file = "/etc/resolv.conf.head"; # Preferably do not use /etc/resolv.conf
# proxy_only=on; # Do not query any name servers beside your ISP's.
timeout=4; # Server timeout; this may be much shorter
# that the global timeout option.
uptest=if; # Test if the network interface is active.
interface=wlan0; # The name of the interface to check.
interval=10m; # Check every 10 minutes.
purge_cache=off; # Keep stale cache entries in case the ISP's
# DNS servers go offline.
}

Notice the file variable which tells pdnsd where to find the nameservers it will query. Once this is complete, the pdnsd daemon can be restarted. Now, NetworkManager must be told to use localhost for DNS lookups. This can be done by right-clicking the nm-applet icon and configuring the wireless for “Automatic (DHCP) Address Only”, and enter 127.0.0.1 as the DNS server. Once this is complete, you can test it with the following commands:

jaigner /var/cache $ dig kernel.org | grep Query
;; Query time: 75 msec
jaigner /var/cache $ dig kernel.org | grep Query
;; Query time: 0 msec


The second time the command was called, the cached result was fetched. If your Query time is greater than 1ms, it is likely that something is misconfigured.

jaigner@turing$ xset r on

This will enable key repeat functionality.

Transfer the file to the root directory of your SD card. Once the file is on your SD card, you can use an application such as Astro file manager to install the file. Simply click on the google maps icon, and click the “update” button. Maps might freeze up the first time you boot it, just wait and it should load fine.

If all the steps worked without error, you should be good to go! Have fun with the new app.
