If you have subscribed to my feed (I have no idea if anyone actually has, and I’m not entirely sure why you would want to but anyway..) I have switched to RSS powered by FeedBurner, it was a really simple process and the reason for doing so is that I like to see which of my posts are well received in order to write better ones in the future. Once the FeedBurner feed has been made it will also give you a guide into replacing all the links to your old RSS feed in order that any new readers will be using it. With page views, traffic sources, returning visitors etc. stats covered by Google Analytics and WordPress have no feedback on who is following your feeds I figured it might be a worth it.

Point of this post being, if you are using my RSS feed it’d be nice if you could change over however the old feed should still get updated so its not a requirement.

Google Wave has been in and out of the trending topics since the first set of beta invites were available, tons of people are still requesting and sharing invites via twitter many of who would usually not even know about Wave at this point. The massive spread of the service must be astronomical in comparison to Google Mail beta back in 2004 when mass communication tools such as Twitter weren’t around, the closest being Myspace which was only a year old and Facebook, just finding it’s feet. The huge impact Twitter has cause on Google Wave brings me to a few questions..

• Should software or web apps be put under this much strain this early on in development?

• It is good that the general public are becoming more aware and involved in beta testing, or should it be left to tech-heads?

• Where would Google Wave be at without Twitter?

• What does how openly people are sharing email addresses on Twitter show us about the publics knowledge of internet security?

This issue is caused by switching from a proxy to a none-proxy network, even when the proxy has been set to direct internet connection and applied system wide if the system has not rebooted it still seems to be configured to be under that proxy.

This issue is caused by switching from a proxy to a none-proxy network, even when the proxy has been set to direct internet connection and applied system wide if the system has not rebooted it still seems to be configured to be under that proxy.

The easiest way to fix it is to go to System > Preferences > Network Proxy. Here change to your networks correct proxy setup then click “Apply System-Wide..” you will be prompted to enter your root password twice and then it will be done. If this does not resolve the issue try logging out and back in again or even rebooting your system, this should have fixed it.

Great guide by wootah from the ubuntuforums.org of how to get the wireless receiver for PC working under linux, using the Userspace Xbox/Xbox360 USB Gamepad Driver for Linux from grumbel. It works pretty much perfectly, I use it as a remote to control my laptop when it is displayed on my TV.

Pretty simple and quick way to add a user to the sudoers list in fedora:

Pretty simple and quick way to add a user to the sudoers list in fedora:

Login as root user:
su
Password: *enter root password here*
Add write permissions to the sudoers file:
chmod +w /etc/sudoers
Add the user (change alex to the user you want to add to sudoers) to sudoers and set no password (so you don’t have to enter a password when using sudo).
echo '<strong>alex</strong> ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers
Remove the write permission from the sudoers file once you have finished writing to protect it, and then exit:
chmod -w /etc/sudoers
exit

Now try testing it out by checking for updates or anything else you need to do as root :-)

To fix this error you will need to edit some of the repo files located in /etc/yum.repos.d/ heres how:

su - cd /etc/yum.repos.d/ gedit fedora.repo

To fix this error you will need to edit some of the repo files located in /etc/yum.repos.d/ heres how:

su -
cd /etc/yum.repos.d/
gedit fedora.repo

In here you are going to want to remove the comments ‘#’ from the lines beginning with baseurl and then comment out the lines beginning with mirrorlist. Now do the same for the file fedora-updates.repo in the same directory.

gedit fedora-updates.repo

Finally you want to add two lines to /etc/hosts file:

gedit /etc/hosts
add these two lines to the bottom of this file:
80.239.156.215          mirrors.fedoraproject.org
213.129.242.84          mirrors.rpmfusion.org

Now try yum update if the error doesn’t show it worked! :)

To set up your surround sound first open up Terminal, or alternatively Alt+F2 and type the following in either: gedit /etc/pulse/daemon.conf

default-sample-channels = 2
You might have a different amount of channels set there but simply change it the amount of speakers you have, the sub doesn’t count so 5.1 will be 5, 6.1 = 6, 7.1 = 7 etc..

Ok now you will need to restart you system for these changes to take effect once thats done test them out with this command:
speaker-test -Dplug:surround51 -c6 -l1 -twav
