Save A List Of Installed Applications On Linux

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

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.
