Believe it or not but the first thing I did after installing Ubuntu 8.04 Hardy Heron on my laptop was finding a compatible Twitter client for Linux that works on Ubuntu. I could have used Twitter IM to post updates through Pidgin or Google Chat but that kills the fun of it.

I rushed to the Synaptic Package Manager hoping to find a Twitter client app right away but very unfortunately none were listed there. Then I did a little research and found some good Twitter clients for Linux that work on Ubuntu.

1. Twitux (download)

Twitux is a Twitter client for the Gnome desktop. The program features include view public, friends and mine timeline, send message, automatic login, add friend and system tray icon.

2. gTwitter (download)

gTwitter a simple GTK+ based application for Linux, designed to interact with Twitter web service. Its written using Mono/C# and some of GNOME dependant libraries. GUI is inspired by Mac client Twitterrific.

3. Spaz (download)

Spaz is a Twitter client for users who value free, open-source software, attractive design, and customizability. It is built entirely in XHTML and Javascript and can be styled using a custom CSS styling file. It is built on the Adobe AIR framework so to install it all you need to have is Adobe AIR on Ubuntu (See the end of the post for this tutorial)

4. Twhirl (download)

Twhirl is a desktop twitter client, based on the Adobe AIR platform. It is one of my favorite Twitter clients as it really very easy to use. Scroll down to see how to get this app working using Adobe AIR on Ubuntu.

5. TwitterFox (download)

TwitterFox is a Firefox Extension that displays updates from your friends and lets you update your status. This extension adds a tiny icon on the status bar that notifies you when your friends update their tweets. Also it has a small text input field to update your tweets. As Ubuntu already comes preinstalled with Firefox so installing this Twitter app is as easy as a pie.

6. Twitter Deskbar (download)

Twitter Deskbar is a Twitter app that integrates with the Gnome Deskbar and lets you post status updates right from your desktop. The installation requires you to have Deskbar widget for Gnome. For detailed instructions please use the download link provided.

7. Twitter Terminal

This is basically a hack for posting to Twitter using the Linux Terminal. You will need cURL ( a client for getting files from servers) to post to Twitter through the Terminal which can be installed using the following command:
sudo apt-get install curl

With cURL installed, you can post to Twitter from the terminal window by using the following syntax:
curl -u yourusername:yourpassword -d status="Your Message Here" http://twitter.com/statuses/update.xml

You will receive a response containing the XML coding for your post which acts as a confirmation that your post was submitted.

8. Alert Thingy (download)

Alert Thingy is basically an Adobe AIR app for FriendFeed but also works for Twitter as well. You can get status updates from your friends and can also post live status updates yourself.

9. Mitter ( Download)

Among mitter features are :

  • clean interface: simple and easy to use
  • supports docking on systray
  • nicely integrated with GNOME desktop
  • has console client

Bonus for Ubuntu users : mitter is also available from GetDeb.net one-click-install portal

All of these apps work brilliantly on Ubuntu so you are good to go with any one of these.

I took this photo of a Kindle 2 hacked by Jesse Vincent at Foo Camp this past weekend. Apparently, aside from being a popular e-book reader, the Kindle is like Lego for Linux geeks. Here’s Jesse’s description of what we’re looking at:

What you see there is a Kindle 2 with the Ubuntu 9.04 port to ARM running in a chrooted environment. On the screen you see xdaliclock in front of an xterm with the remains of a “top” command and a few mildly embarrassing typos.To open up the Kindle, I used the USB networking debug mode Amazon left hanging around when they first shipped the Kindle 2, a statically linked telnetd and a cross-compiler to bootstrap myself. From there, I built a daemon that can convert DRM-free PDFs and ePubs into something Amazon’s reader on the Kindle can deal with.

After that, I started to get curious about what else might be possible. It only took a few evenings to get a moderately usable Ubuntu environment running.

Mostly, the Kindle is a lovely little Linux box. Getting X working took a bit of hacking, but everything else “just works” with very little configuration.

Ubuntu Netbook Remix 9.04  is Ubuntu fo netbooks.


Ubuntu Netbook Remix is a ‘remix’ of the standard Ubuntu Desktop release to enable it to work better on devices with small screens, such as Netbooks (sub-notebooks).

Ubuntu Netbook Remix is optimised to run on a new category of affordable Internet-centric devices called netbooks. It includes a new consumer-friendly interface that allows users to quickly and easily get on-line and use their favourite applications. This interface is optimised for a retail sales environment.

Canonical has collaborated with Intel and is working with a number of OEM’s to deliver Ubuntu on netbooks in retail. In keeping with the philosophy of our best work being available to everyone, the core remix product is available to all through the Canonical repositories. This version is free to download and modify by any user.

What is a remix?

A remix is a ‘respun’ version of Ubuntu built for a specific purpose. Although Canonical has encouraged community projects to use this terminology for some time, this is the first time that Canonical has used it. We are using it to differentiate from an ‘Edition’ which we consider a complete version with daily builds suitable for the average user with no additional work beyond installing the CD. To use the Ubuntu Netbook Remix you need to install packages on top of an existing Ubuntu installation and you may have some compatibility issues depending on your hardware profile. For now we recommend it only for experienced Linux users or commercial OEMs and ODMs engage with Canonical for support and service offerings.

In addition to the Ubuntu Netbook Remix there will be pre-installed remixes made available on manufacturer’s machines. These will contain software that is not free and built for specific hardware profiles unique to the OEM. These will not be publicly available as we do not have the right to redistribute the software.

All of the initial Ubuntu Netbook remixes combine optimisations from the Moblin project for Intel® AtomTM processors and it is specially designed for netbooks. Intel and Canonical are working to create a new computing experience across a rapidly expanding category of portable devices.

Need to monitor Linux server performance? Try these built-in command and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as:

  1. Finding out bottlenecks.
  2. Disk (storage) bottlenecks.
  3. CPU and memory bottlenecks.
  4. Network bottlenecks.

#1: top – Process Activity Command

The top program provides a dynamic real-time view of a running system i.e. actual process activity. By default, it displays the most CPU-intensive tasks running on the server and updates the list every five seconds.

Fig.01: Linux top commandFig.01: Linux top command

Commonly Used Hot Keys

The top command provides several useful hot keys:

Hot Key Usage
t Displays summary information off and on.
m Displays memory information off and on.
A Sorts the display by top consumers of various system resources. Useful for quick identification of performance-hungry tasks on a system.
f Enters an interactive configuration screen for top. Helpful for setting up top for a specific task.
o Enables you to interactively select the ordering within top.
r Issues renice command.
k Issues kill command.
z Turn on or off color/mono

#3: w – Find Out Who Is Logged on And What They Are Doing

w command displays information about the users currently on the machine, and their processes.
# w username
# w vivek

Sample Outputs:

 17:58:47 up 5 days, 20:28,  2 users,  load average: 0.36, 0.26, 0.24
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

root     pts/1       17:43    0.00s  0.03s  0.00s w

#4: uptime – Tell How Long The System Has Been Running

The uptime command can be used to see how long the server has been running. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
# uptime

 18:02:41 up 41 days, 23:42,  1 user,  load average: 0.00, 0.00, 0.00

1 can be considered as optimal load value. The load can change from system to system. For a single CPU system 1 – 3 and SMP systems 6-10 load value might be acceptable.

#5: ps – Displays The Processes

ps command will report a snapshot of the current processes. To select all processes use the -A or -e option:
# ps -A
Sample Outputs:

  PID TTY          TIME CMD

#14: tcpdump – Detailed Network Traffic Analysis

The tcpdump is simple command that dump traffic on a network. However, you need good understanding of TCP/IP protocol to utilize this tool. For.e.g to display traffic info about DNS, enter:
# tcpdump -i eth1 'udp port 53'
To display all IPv4 HTTP packets to and from port 80, i.e. print only packets that contain data, not, for example, SYN and FIN packets and ACK-only packets, enter:
# tcpdump 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
To display all FTP session to, enter:
# tcpdump -i eth1 'dst and (port 21 or 20'
To display all HTTP session to
# tcpdump -ni eth0 'dst and tcp and port http'
Use wireshark to view detailed information about files, enter:
# tcpdump -n -i eth1 -s 0 -w output.txt src or dst port 80

#15: strace – System Calls

Trace system calls and signals. This is useful for debugging webserver and other server problems. See how to use to trace the process and see What it is doing.

#16: /Proc file system – Various Kernel Statistics

/proc file system provides detailed information about various hardware devices and other Linux kernel information. See Linux kernel /proc documentations for further details. Common /proc examples:
# cat /proc/cpuinfo
# cat /proc/meminfo
# cat /proc/zoneinfo
# cat /proc/mounts

17#: Nagios – Server And Network Monitoring

Nagios is a popular open source computer system and network monitoring application software. You can easily monitor all your hosts, network equipment and services. It can send alert when things go wrong and again when they get better. FAN is “Fully Automated Nagios”. FAN goals are to provide a Nagios installation including most tools provided by the Nagios Community. FAN provides a CDRom image in the standard ISO format, making it easy to easilly install a Nagios server. Added to this, a wide bunch of tools are including to the distribution, in order to improve the user experience around Nagios.

18#: Cacti – Web-based Monitoring Tool

Cacti is a complete network graphing solution designed to harness the power of RRDTool’s data storage and graphing functionality. Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices. It can provide data about network, CPU, memory, logged in users, Apache, DNS servers and much more. See how to install and configure Cacti network graphing tool under CentOS / RHEL.

#19: KDE System Guard – Real-time Systems Reporting and Graphing

KSysguard is a network enabled task and system monitor application for KDE desktop. This tool can be run over ssh session. It provides lots of features such as a client/server architecture that enables monitoring of local and remote hosts. The graphical front end uses so-called sensors to retrieve the information it displays. A sensor can return simple values or more complex information like tables. For each type of information, one or more displays are provided. Displays are organized in worksheets that can be saved and loaded independently from each other. So, KSysguard is not only a simple task manager but also a very powerful tool to control large server farms.

#20: Gnome System Monitor – Real-time Systems Reporting and Graphing

The System Monitor application enables you to display basic system information and monitor system processes, usage of system resources, and file systems. You can also use System Monitor to modify the behavior of your system. Although not as powerful as the KDE System Guard, it provides the basic information which may be useful for new users:

  • Displays various basic information about the computer’s hardware and software.
  • Linux Kernel version
  • GNOME version
  • Hardware
  • Installed memory
  • Processors and speeds
  • System Status
  • Currently available disk space
  • Processes
  • Memory and swap space
  • Network usage
  • File Systems
  • Lists all mounted filesystems along with basic information about each.

Bounce: Additional Tools

A few more tools:

  • nmap – scan your server for open ports.
  • lsof – list open files, network connections and much more.
  • ntop web based tool – ntop is the best tool to see network usage in a way similar to what top command does for processes i.e. it is network traffic monitoring software. You can see network status, protocol wise distribution of traffic for UDP, TCP, DNS, HTTP and other protocols.
  • Conky – Another good monitoring tool for the X Window System. It is highly configurable and is able to monitor many system variables including the status of the CPU, memory, swap space, disk storage, temperatures, processes, network interfaces, battery power, system messages, e-mail inboxes etc.
  • GKrellM – It can be used to monitor the status of CPUs, main memory, hard disks, network interfaces, local and remote mailboxes, and many other things.
  • vnstat – vnStat is a console-based network traffic monitor. It keeps a log of hourly, daily and monthly network traffic for the selected interface(s).
  • htop – htop is an enhanced version of top, the interactive process viewer, which can display the list of processes in a tree form.
  • mtr – mtr combines the functionality of the traceroute and ping programs in a single network diagnostic tool.

Even as a child, I knew that Pixie Sticks were just trouble. The paper tubes loaded with colorful yet mysteriously flavorless sugar weren’t particularly tasty, and too many of them led to mom and dad either threatening to pull the car over or hinting ominously about what would happen if they “had to tell me again.” Parents today know that in addition to the traditional side effects, Pixie Sticks aren’t terribly good for USB ports, either.

That’s not the case with the other sort of Sugar. Sugar, the kid-friendly open source desktop that was featured first on the OLPC XO laptop is now available (in a beta release) as a liveUSB image. The Sugar on a Stick environment is powered by Fedora 11 and features familiar Sugar desktop applications and functions, as well as new educational and collaborative tools, such as the InfoSlicer online content editor, remixer, and delivery application.

Sugar on a Stick, like other live media distributions, runs without altering any software or data on the computer’s existing hard drive. The Sugar on a Stick project plans on offering several configurations for the live image — so that a child’s work can be saved on the flash drive whether it is run natively or through a virtualization or emulation mode. The liveUSB image requires a flash drive of at least 1 GB in size (formatted as a FAT32 or FAT16 partition). Sugar on a Stick can peacefully coexist with existing data on flash drives meeting the size and formatting criteria. The Sugar Labs Wiki explains how to create the image on Windows, Linux, or Mac platforms, as well as instructions on getting it up and running in a virtual environment.

Netbooks and inexpensive, kid-friendly hardware are great ideas, but in many cases, they simply aren’t possible (or necessarily desirable). Packaging Sugar in this format offers the educators — and children — using it many of the same benefits at a much lower price point. While you might not wish to use your child’s school work as part of the beta testing, the Sugar on a Stick team invites educators, parents, and even their interested progeny to try the software on as many devices as possible and report back with bugs and feedback. The Sugar on a Stick team hopes to offer students a polished 1.0 release by the third quarter of 2009 — just in time to head back to class.
