The Falling Sand Game
Be Warned! This is a very addictive game! I am not normally a fan of any type of computing games, but I found myself playing on this for hours on end.
I'm sure most of you would have heard and played the flash version of this game somewhere on the Internet. There are many different version of it now, each with their own set of elements to play around and experiment with. The original version of this game is now available to download for Linux. You may wonder why you would want to download it, and just play it online. Well The main benefit of downloading this game, is that you get to install and use hundreds of different mods that various people have made for it. Some of the mods include a fireworks pack, volcano add-ons and an acid mod. Some of the more extreme mods give you the ability to make guns, cars, and even life forms!
To download The Falling Sand Game:
wget http://www.piettes.com/fallingsandgame/fsg-4.4
Once downloaded, you must set the correct permissions so that you can execute it:
chmod u+x fgs-4.4
Many people have said that they are unable to get this game to work. Tinivole from the UbuntuForums has found the solution for this:
sudo ln -s /usr/lib/libexpat.so /usr/lib/libexpat.so.0
Ubuntu 9.04 Wallpapers
Spice up your new Ubuntu 9.04 installation with some of these fantastic wallpapers. These are all Alpha release wallpapers that didn't quite manage to make it into the final release. I am sure you will agree with me that many of these really should have made it!
All of the below images, and many more can be found from the Artwork section of the official Ubuntu Wiki
Save A List Of Installed Applications
Firstly I would like to apologize for the lack of updates to this site over the last few weeks. This is down to some personal problems I have been having, and due to Jaunty messing with my display on my MSI Wind. All is back to normal now, and I'm ready to go!
I have recently used this very neat trick within the dpkg packet manager. Have you ever started a fresh install, and forgot which applications you had installed on your old installation? It's a pain. Even when you think you have them all installed, you go to do something, and realize Damn! I forgot to install that.
If you load up a blank terminal, and run the following command:
dpkg --get-selections > apps.txt
This will store a list of every application that is currently installed to a file called apps.txt. If you are wanting to re-install your OS, then make sure that you save this file to a USB stick!
Once you are ready to install all your applications again:
dpkg --set-selections < apps.txt
dselect update
apt-get dselect-upgrade show
Now after a lot of downloading and installing, you will once have all of your applications installed again. It may be an idea before you re-install your OS to back up the /etc/apt/sources.list file, so that you are able to download the applications that you may of got else where.
If you have any questions about this methord, then please leave a comment!
Twittering With Ubuntu
Over the past 6 months, the popularity of Twitter has sky rocketed, with the worlds most biggest celebrities using it - With @Obama being one of the top users with the highest amount of followers.
So what is Twitter? Twitter is known as a 'micro-blogging' website that allows the user to send a short message (know as a 'Tweet') to their friends (known as 'Followers'). The idea is to update what it is you are doing, thinking, working etc. at that moment in time. Your status update can contain a maximum of 140 characters, and once sent, anyone that is following you will receive your update. If one of your followers updates their status, you will then receive their updates. It is a really quick, and simple way of staying in touch with your friends, family and co-workers.
Twitter Clients
Rather then going to Twitter.com every time you want to update your status, or view your friends updates, you can download a Twitter Client. This is a small application that will let you update, view updates, send Direct Messages etc. A few of them have more features then the others, and below are the most popular ones available for Ubuntu.
gTwitter
gTwitter is a simple GTK based application for the GNOME environment. gTwitter is inspired upon the Mac twitter client Twitterrific
At the moment, gTwitter is still in its Beta stages, so there are only the basic features that are available, which include reading both your friends, and the public timeline (with users avatars) and updating your status.
To install gTwitter:
sudo apt-get install gtwitter
You will now be able to run gTwitter from Applications -> Internet -> gTwitter
Twitux
Twitux for the GNOME desktop environment, is very similar in design and looks of gTwitter. When you recive a new tweet, you will be notified by a notification bubble.
To install Twitux:
sudo apt-get install twitux
You will now be able to run gTwitter from Applications -> Internet -> Twitux
Adobe Air Clients
There are many Clients that run using Adobe Air. View the following post for instructions on installing and using Adobe Air on Ubuntu.
Twhirl
Twhirl being one of the more popular clients to run on Adobe Air, has many features that other clients do not have. You have the ability to choose from many different themes, and to change how the application behaves. Twhirl gives you the ability to login not only to Twitter, but to Laconi.ca, FriendFeed and Seesmic. With Direct Messaging, Tweets, favorite tweets, search, archive and many more features, I think this is the best Twitter Client out for Adobe air.
To download Twhirl, you need Adobe Air installed. Once installed: Right Click, Save As the following link: Download Twhirl 0.9
Tweet Deck
Tweet Deck is a unique way of interacting with Twitter. This client will enable you to categorize your tweets into different columns. You could have your Tweets in one column, your replies in another, and your direct messages in a third column. If you are a Twitter-Whore, then this is the client for you! Within TweetDeck, you can customize to which columns you want, and where you want them. Once an update is available (eg, you get a new Direct Message) the columns will automatically update.
  
After installing Adobe Air, Right Click, Save As the following link: Download Tweet Deck
Spaz
Spaz is a simple to use Twitter client. Included with Spaz are a number of different themes to get the look and feel that you want. This client comes with built in short URL creation (is.gd, bit.ly, snurl.com etc.) - The shorter your URL, the more characters you have to tweet! To find out what the Spaz dev-team are up to, follow them on twitter here: @Spaz
To download, Rick Click, Save As the following link: Download Spaz
Alert Thingy
Alert Thingy brings all of your latest updates from all the most popular social networking sites (Digg, Facebook, Ping.fm & many more).
To download, Right Click, Save As the following link: Download Alert Thingy
FireFox Plugin Clients
Don't want more applications running then you really need? Well there are a few plugins available for FireFox that will allow you to update your status
TwitterFox
 TwitterFoxis a plugin for Firefox that adds a small icon on to the status bar, which will notify you when any of your followers posts a new tweet. This client comes with the ability to send and delete, and re-tweet your tweets.
Twitter Bar
Twitter Bar turns your address bar into a Twitter Bar! This is a very simple methord of posting to twitter. Simply write your tweet in the address bar, and click the twitter icon, or end the message with --post
Command Line Clients / Methods
Yes, you can even update your twitter account from the command line! This is great news for if you are running a server, or you just prefer life without the graphical user interface.
cURL
The most popular way of doing this is by using cURL. If you haven't already got cURL installed, then you really should download and install it right away! It can be a very useful and powerful program.
sudo apt-get install curl
Now you are ready to update your Twitter account. Using cURL, you are able to update pretty much everything using Twitter's API. To update your Twitter stats, you can use the following command:
curl --basic --user "USERNAME:PASSWORD" -d status="TWEET MESSAGE" https://twitter.com/statuses/update.xml
I recommend using HTTPS as you are sending your password over the net...
Wget
Using wget to update your status is very similar to that of cURL:
wget --keep-session-cookies --http-user=USERNAME --http-password=PASSWORD --post-data="status=MESSAGE" https://twitter.com:80/statuses/update.xml
TTYtter
Unlike the previous two in this section, TTYtter is a command line based Client, with the functionality to send and relive tweets, direct messages, follow / un-follow a user, and re-tweeting. For more in-depth information and instructions on how to install this client, please visit their website at: http://www.floodgap.com/software/ttytter
I hope that this post has made things a little easier for you when it comes to picking what Twitter Client you want to work with. If you have any questions about the above clients, or you would like to tell me about any other clients that you use, then please use the comment section below.

Using wget To Download Entire Websites
Basic wget Commands:
To download a file from the Internet type:
wget http://www.example.com/downloads.zip
If you are downloading a large file, for example an ISO image, this could take some time. If your Internet connection goes down, then what do you do? You will have to start the download again. If you are downloading a 700Mb ISO image on a slow connection, this could be very annoying! To get around this problem, you can use the -c parameter. This will continue the download after any disruptions. eg:
wget -c http://www.example.com/linux.iso
I have came across some websites that do not allow you to download any files using a download manager. To get around this,
wget -U mozilla http://www.example.com/image.jpg
This will pass wget off as being a Mozilla web browser
Downloading Entire Sites:
Wget is also able to download an entire website. But because this can put a heavy load upon the server, wget will obey the robots.txt file.
wget -r -p http://www.example.com
The -p parameter tells wget to include all files, including images. This will mean that all of the HTML files will look how they should do.
So what if you don't want wget to obey by the robots.txt file? You can simply add -e robots=off to the command like this:
wget -r -p -e robots=off http://www.example.com
As many sites will not let you download the entire site, they will check your browsers identity. To get around this, use -U mozilla as I explained above.
wget -r -p -e robots=off -U mozilla http://www.example.com
A lot of the website owners will not like the fact that you are downloading their entire site. If the server sees that you are downloading a large amount of files, it may automatically add you to it's black list. The way around this is to wait a few seconds after every download. The way to do this using wget is by including --wait=X (where X is the amount of seconds.)
you can also use the parameter: --random-wait to let wget chose a random number of seconds to wait. To include this into the command:
wget --random-wait -r -p -e robots=off -U mozilla http://www.example.com
Other Useful wget Parameters:
--limit-rate=20k : Limits the rate at which it downloads files. (20Kb/s)
-b : Continues wget after logging out. Very useful if you are connecting to your home PC via SSH.
-o $HOME/wget_log.txt : Logs the output of the wget command to a text file within your home directory. Useful for if you are using wget in the background, as you can check for any errors that may appear.
