Firefox 3.6 and Java

Firefox 3.6 has just been released today and i have updated to the latest release using automatic updates (ie. i'm not using Slackware's Firefox package). This release brings many improvements to Firefox 3.x releases, with multiple personas, WOOF font format, PluginCheck, improved HTML 5 and CSS 3 support, including CSS Gradient, and many more. In short, it's a must-have upgrade for this week.

Unfortunately, some add-on or extensions will be broken due to some changes in Firefox 3.6 which should force the extension developers to change their code a little bit in order to make it compatible with Firefox 3.6. So far, only two of my add-ons which are not compatible (yet).

Other things to consider before moving to Firefox 3.6 is how Java application interacts with Firefox 3.6. It has been stated on many media that Firefox 3.6 changes the Java Plugin, so libjavaplugin_oji.so will not longer recognized when you type about:plugins in the address bar. You will also need to upgrade your Java installation to Update 10 or above. The latest version up to the time i write this post is Update 18.

To have Java apps working again in Firefox 3.6, you will have to go to Plugins directory of your Firefox installation (mine is in /opt/firefox/plugins), and then run ln -s /usr/java/jdk1.6.0_18/jre/lib/i386/libnpjp2.so . (note the dot and also the path to Java will be different if you are using Slackware's Java package). That's it and your Java application will work as it used to be.

Running Rsync Via Proxy

One way to get the latest Slackware updates is by running rsync to syncronize your local repository and the main repository that hold the Slackware packages. Eric Hameleers has provided a great script called rsync_current.sh and how i modified this tool has been discussed on my previous post. In general, it works, except for one problem, when your computer is connecting to the Internet through a proxy.

My workstation at my office is connected to the Internet through a proxy, so i can't use normal rsync to work normally. I browsed the web and i found this site which tells us about how we should modify our squid configuration to allow rsync connection from any computer from our local networks. I asked my sysadmin to try this script. He agreed and he updated the squid configuration on the proxy.

Next, i need to update my environment variable RSYNC_PROXY to the host of the proxy and also the port. Let's say you are running a proxy on 192.168.1.1 and port 8080, then you need to run …

NVidia Legacy Unix Driver Update

NVidia has released an updated legacy drivers to support X.Org 1.19 with ABI 23. It has been mentioned in the UNIX drivers, but you can directly find the drivers from the links below:
NVidia 304.134 (x86x86_64)NVidia 340.101 (x86, x86_64) I have tested the 304.134 driver and it's working great here. I can finally remove x from my /etc/slackpkg/blacklist file since it's a showstopper for me.
Aside from legacy driver, NVidia has also released their latest driver 375.26 (x86, x86_64), which brings support for newer cards and also many new features (including X.Org 1.19 with ABI 23 support).
