“COOL” Dock Applications for Ubuntu 12.04

Dock  is Cool, specially if you don’t like the default panel in your desktop (or if you just want an eye candy desktop).

In Ubuntu 12.04 (Precise Pangolin), a lot of users complained about the Unity Desktop (which is the default one) –  the loss of productivity due to sudden changes, ease of use etc. In that case, you may try some other desktop or try using Dock as a substitute for panel. It looks beautiful – and of course it would be more easy to start/find apps and manage windows using this dock app.

Best Dock Apps for Ubuntu 12.04 LTS

1. GLX Dock (Cairo Dock + OpenGL)

GLX Dock

GLX-Dock  is nothing but the Cairo Dock, mixed with some other plugins and components so that it can use your computer’s graphics capabilities in better way (hardware acceleration). Cairo Dock is a light-weight, simple and easy to use dock application.

It has lot of cool features – taskbars, launchers, shortcuts, GNOME 2 style application menu, plugins (to extend the default features), workspace switcher, themes etc. You can easily customize cairo dock – the look, animation, effects, features, shortcuts, applet/plugins and default apps for Music, Mail, Chat etc.

 Customizing Cairo Dock with Cairo Configuration Manager

For advanced customization, go to  Help -> Cairo Dock -> Configure. Then a Cairo Dock Configuration Window will appear (above snapshot) – where you can customize everything such as Appearance, Add-ons and Keyboard Shortcuts.

Don’t forget to checkout the Add-On section – it contains a lot of useful and funny applets. Some of the most useful plug-ins are – Clipboard History, Drop to Share, Messaging Menu, RSS Reader, Switcher, Slider, Stack, Power Manager etc. Just select the plug-ins you want to try and click Apply to get the immediate effect.

2. Docky – A Dock that just works!

Docky is another elegant, cool and powerful Dock application. It’s very fast and easy to use. By default, it looks very simple – in 2D mode but you can enable 3D mode from settings to make it more cooler.

Docky doesn’t uses OpenGL but it works out of box, in GNOME Desktop environment (without any unnecessary configurations). So if you want a Dock that just works – then Docky is best for you.

Install Docky in Ubuntu 12.04 LTS

sudo apt-get install docky

Eidete – A Screencasting Application that really works on Ubuntu 12.04

In Ubuntu 12.04 (Precise Pangolin) LTS, there are few great applications available for screencasting – such as RecordMyDesktop, Kazam and built in tool (starts/resumes with Ctrl+Alt+Shift+r) in Gnome shell desktop (although it doesn’t record voice) but none of them worked well in Ubuntu 12.04 (with Unity).

Kazam was irritating like hell – when I completed the recording it crashed and I couldn’t save anything (although it was working fine for smaller duration (couple of minutes)), besides that – it was consuming a lot of RAM (so there may be some sort of ‘memory leak’). RecordMyDesktop was also behaving very strange, User Interface is very confusing and it also crashes a lot (resource consumption was also very high, my pc became unresponsive for a while).

Eidete : Screencast Recording Software for Ubuntu

Finally, I tried Eidete – it worked like charm. I’ve recorded more than 6 videos(till now) and there was no problem at all. So if you guys had any problem recording screencasts with Ubuntu, then I recommended you to try Eidete.

Eidete is a simple application, it has all the basic features such as audio/video options, recording area selection, display mouse behavior and clicks, timer countdown, pause/resume etc. Finally, it saves the screencast into web friendly format (.webm).

eidete-recording

Recording is very easy, after hitting the record button, the recording process starts within 5 seconds (timer). Finally, if you want to finish then click on Eidete Launcher, and click Finish(then you will get a new window for saving the recorded file).

How to Install Eidete in Ubuntu 12.04

Since, it’s not there in official package repository so you need to add the PPA for Eidete. Open a terminal and execute –

sudo add-apt-repository ppa:shnatsel/eidete-daily
sudo apt-get update
sudo apt-get install eidete

MyPaint - Digital Painting App

Digital Painting Application for Ubuntu (12.04) : MyPaint

GNU/Linux distributions such as Ubuntu, Linux Mint etc are becoming most popular among desktop users (even the non-technical users prefer Ubuntu or windows), the user base is growing very fast. When it comes to digital and graphics applications, Ubuntu lacks few cool apps mostly from Adobe (e.g Photoshop, Illustrator etc) but there are good alternatives such as GIMP, Blender, Inkscape, MyPaint etc.

MyPaint - Digital Painting App

MyPaint is a simple and easy to use application, for digital painters. It comes with a large collection of brushes and most importantly – it works well with wacom graphics tablet (and it’s also pressure sensitive) – which is the largest manufacturer of pen displays devices – graphics tablets.

How to Install MyPaint in Ubuntu 12.04 or (Linux Mint)

Open a terminal and execute –

sudo apt-get install mypaint

Note : Although, you can also use MyPaint from older version of Ubuntu but you are recommended to install (upgrade) 12.04 as it’s the latest stable release (and it’s a Long Term Support release) from Canonical. Unity, the default user interface in 12.04, has also improved a lot – and it looks very promising for new users.

How to Clear DNS Cache in Ubuntu 12.04

DNS – Domain Name System, is one of the core component of web that provides us human friendly domain names, mapped to computer friendly numeric address (called I.P (Internet Protocol) Address). Each time – when you visit a website – your computer/browser performs a DNS query (searching for IP address for the requested domain name (website you visit)).

By default, our computer cache DNS results in order to provide fast lookup in future- and that’s really good (because it’s efficient and saves a lot of resources), but some times it creates a problem specially when a domain gets new IP address(s) (or in other words, the server is changed). In such case the cached result may prevent you from viewing the latest website/app for your domain. So that’s where – flushing the DNS cache results, is mandatory.

There are various ways to clear dns cache in Ubuntu  but using nscd (name service cache daemon) is very simple and straightforward (and it works with almost all – commonly used GNU/Linux distributions such as Fedora, Mint, OpenSuse etc).

Install NSCD Daemon in Ubuntu 12.04 LTS

open a terminal and execute –

sudo apt-get install nscd

Clear DNS Cache from terminal

nscd-restart

sudo /etc/init.d/nscd restart

That’s All. If you want to know more about the features of nscd then run the command with -help flag –
