To merge two or more mp3 you will need to get the program called mp3wrap. To split two files you can use program called mp3splt. You can install them by typing:

sudo apt-get install mp3wrap mp3splt

Now you can merge two mp3 files (let’s say 1.mp3 and 2.mp3) by typing:

mp3wrap merged.mp3 2.mp3 1.mp3

note that the merged.mp3 will start with 2.mp3 and finish with 1.mp3

You can split mp3′s now by typing:

mp3splt merged.mp3 0.0 1.2 3.4

this will split file merged.mp3 into two parts:

00:00 – 01:02
01:02 – 03:04

where xx:xx represents minutes:seconds.

If you have problems splitting files merged with mp3wrap delete whatever mp3wrap add to filename and then try again. You shouldn’t experience any problems now.

To see more info on these commands type

man mp3wrap

or

man mp3splt

I have the Firefox PPA set. It updated today to Firefox 6. Ever since I cannot access my Add-ons. It just says Loading, and never stops.

Anybody know how I can fix this?

Answers:

Simply don’t use the ppa, then force the previous packages to downgrade (from synaptic menu: select firefox then package force), or there may be an add-on conflict

firefox -safe-mode

Try disabling some one at a time till you find the issue I’m not having any issues i got a performance boot it feels like. Sadly I found out that ff7 will have much better memory usage now I am already impatient about getting it.

A Firewall is a program (software) or a device which allows us to set different types of rules for a network i.e how the packets will be treated at different ports ..and it’s very widely used in protecting a computer from unauthorized/unwanted access through a network. Due to an exponential growth in computer related crimes, Firewall is a mandatory application for every computer users.

Ubuntu 11.04 – Natty Narwhal or any other Linux distros is very secure by default as they have built in firewalls running by default. So normal Ubuntu users do not need any firewall (Unlike the windows users do because Windows is insecure by default! , Comodo is an excellent firewall for Windows users) in order to protect themselves from crackers or hackers or cyber criminals.

Advanced or ‘geeky’ Ubuntu users may need (or they just want to do that for learning purposes) to set inbound and outbound traffic rules/policies manually for any ports (I mean virtual or software ports), In that case you just need to use UFW (Uncomplicated Firewall; a frontend of IPtables, which works as an interface to netfilter (Package Filtering System provided by Linux Kernel)) , which is installed by default on all Ubuntu versions, but by default it has only Command Line Interface. So in this post you will learn how to install a front end for UFW, Firewal Configuration (gufw), to manage and configure UFW easily in GUI mode. gufw is a simple (probably the best and fast) firewall configuration software that works! and got 5 star in Ubuntu Software Center ratings. You may need to enable (by check the square box) the universe repository in Synaptic Package Manager -> Settings ->Repositories -> Ubuntu Software .

How to install Firewall Configuration Application – gufw on Ubuntu 11.04

1. Open Ubuntu Software Center and search for ‘gufw’.
2. Then, click on install button in the search result, and enter your login password if required.
3. Now, wait for the installation to complete ..relax it will hardly take a minute..
4. That’s All..

Alternative Way – Install gufw from Command Line / Terminal

If you enjoy terminal on Ubuntu then the best way to install is to use terminal/shell (bash). Open terminal (CTRL+ALT+T) and enter the command(s)  -

sudo apt-get install gufw

MPlayer is a movie player which runs on many systems (see the documentation). It plays most MPEG/VOB, AVI, Ogg/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, RealMedia, Matroska, NUT, NuppelVideo, FLI, YUV4MPEG, FILM, RoQ, PVA files, supported by many native, XAnim, and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5, WMV and even H.264 movies.

Another great feature of MPlayer is the wide range of supported output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, but you can use GGI, SDL (and this way all their drivers), VESA (on every VESA compatible card, even without X11!) and some low level card-specific drivers (for Matrox, 3Dfx and ATI), too! Most of them support software or hardware scaling, so you can enjoy movies in fullscreen. MPlayer supports displaying through some hardware MPEG decoder boards, such as the Siemens DVB, DXR2 and DXR3/Hollywood+.

MPlayer has an onscreen display (OSD) for status information, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS and our own: MPsub). DVD subtitles (SPU streams, VOBsub and Closed Captions) are supported as well.
