Install Subsonic:

The official website provides the DEB installer for Ubuntu users. It can be download by clicking the below link:

Subsonic-4.8.deb

Subsonic requires Java, so first install OpenJDK from Ubuntu Software Center or Oracle Java from ppa.

Then double-click on the downloaded DEB package and select install on Ubuntu Software Center. Click ‘Ignore and install’ if you get the below dialog.

Change user:

By default the Subsonic process is run as the root user. To improve security it is strongly advised that you run it as a dedicated user with less powerful privileges. You can specify this user by setting the SUBSONIC_USER variable in /etc/default/subsonic.

To do so, press Alt+F2, type in gksudo nautilus to open file browser with root permission. Then change username to yours in the picture.

subsonic-user

Note that non-root users are by default not allowed to use ports below 1024. Also make sure to grant the user write permissions in the music directories, otherwise changing album art and tags will fail.

After all, restart your computer and open the Subsonic web page on http://localhost:4040.

jNetMap: Open-Source Graphical Network Monitoring and Mapping Tool

Last updated: July 21, 2013

jNetMap is a graphical network monitoring and documentation tool. It will ping all registered devices every x minutes, updating the status according to the result of the ping.

jNetMap helps you to keep an eye on you network. You can draw a graphical representation of your network, and jNetMap will periodically check if the devices are still up or a service is still running. You can also set up E-mail notifications or let jNetMap execute a script when a device goes down or comes up again. Additionally, you may attach notes to a device, initiate an RDP/VNC/SSH connection to a device and much more.

Note: jNetMap is not a network discovery/auditing tool, there are better tools out there for that. And for an enterprise grade monitoring solution, you should check out Nagios instead. The idea here is to have a mission control center-style display for networks.

Install jNetMap on Ubuntu:

The Getdeb repository provides the packages for Ubuntu and Linux Mint user. Supports Ubuntu 10.04 Lucid and higher.

To add the ppa and install jNetMap, press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run below commands:

Last updated: July 21, 2013

Xfce4 Composite Editor is a simple GUI tool that allows to configure the various Xfce4 Window Manager compositor settings that are not available via the Window Manager Tweaks control panel.

The developer of Xfce Theme Manager wrote this simple tool, and it has the ability to control below settings:

  • Shadow opacity.
  • Shadow delta X, Y, width and height.
  • move window opacity.
  • inactive window opacity.
  • frame opacity.
  • resize window opacity.
  • popup opacity.

Also it provides options to swich on / off composite, dock shadow, frame shadow, pop-up shadow and Restart VM to apply changes.

Below is what the developer said in GTK-Apps, “These settings are available via the xconf settings editor but that is one of the most awkward GUI’s I have ever used as you have to select the xfwm4 channel, expand the tree, scroll to the option you want, select it, click edit, change the setting and click save, then the tree gets collapsed and you have to start again! So this nice simple GUI to control the composite manager, the settings are self explanatory.”

Install Xfce4 Composite Editor

One Command to Make ISO Image from Live CD/DVD in Ubuntu

Last updated: July 20, 2013

This simple and brief tutorial will show you how to backup live CD or DVD to iso image on Ubuntu Linux using dd command.

dd is a command on Unix and Unix-like operating systems whose primary purpose is to convert and copy a file. On Unix, device drivers for hardware (such as hard disks) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read from (and in some cases write to) these files. As a result, dd can be used for tasks such as backing up the boot sector of a hard drive, and obtaining fixed amount of random data.

To make iso image out of CD or DVD:

Insert your live CD or DVD into computer, then you can check the device name by running below command:

df -lh

You’ll get a similar output. The last line tells the device name /dev/sr0 and mount point /media/handbook/CD-Rom

Filesystem Size Used Avail Use% Mounted on
/dev/sda6 92G 47G 41G 54% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 870M 4.0K 870M 1% /dev
tmpfs 176M 980K 175M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 878M 3.5M 874M 1% /run/shm
none 100M 56K 100M 1% /run/user
/dev/sr0 807M 807M 0 100% /media/handbook/CD-Rom

Now, use below command to create iso from it:

dd if=/dev/sr0 of=~/backup.iso bs=1000000 count=512 &&sync

Here if reads from file /dev/sr0, of write to file backup.iso, ~/ means user home directory. The value of ‘bs’ means read and write up to 1000000 bytes at a time.

For more, run:

man dd

CherryTree: Best Ubuntu Note-Taking App for Programmers

Last updated: July 20, 2013

CherryTree is a hierarchical note taking application, featuring rich text and syntax highlighting, storing data in a single xml or sqlite file.

CherryTree is perfectly suitable not only for taking notes, but also for managing code snippets. The application supports syntax highlighting for many popular programming languages, so you can use the application as a programmer’s scratchpad. You can also insert code snippets directly into notes using so-called code boxes.

Features:

  • rich text (foreground color, background color, bold, italic, underline, strikethrough, small, h1, h2, h3, subscript, superscript, monospace)
  • syntax highlighting (only when the rich text is disabled in the current node)
  • images handling: insertion in the text, edit (resize/rotate), save as png file
  • lists handling (bulleted, numbered, to-do and switch between them, multiline with shift+enter)
  • simple tables handling (cells with plain text), cut/copy/paste row, import/export as csv file
  • codeboxes handling: boxes of automatically highlighted text into normal rich text
  • alignment of text, images, tables and codeboxes (left/center/right)
  • hyperlinks (links to webpages, links to nodes/nodes + anchors, links to files, links to folders)
  • intra application copy/paste: supported single images, single codeboxes, single tables and a compound selection of rich text, images, codeboxes and tables
  • cross application copy/paste (tested with openoffice and gmail): supported single images, single codeboxes, single tables and a compound selection of rich text, images, codeboxes and tables
  • copying a list of files from the file manager and pasting in cherrytree will create a list of links to files, images are recognized and inserted in the text
  • print & save as pdf file of a selection / node / node and subnodes / the whole tree
  • export to html of a selection / node / node and subnodes / the whole tree
  • export to plain text of a selection / node / node and subnodes / the whole tree
  • toc generation for a node / node and subnodes / the whole tree, based on headers h1, h2 and h3
  • find a node, find in current node, find in all nodes
  • replace in node names, replace in current node, replace in all nodes
  • iteration of the latest find, iteration of the latest replace, iteration of the latest applied text formatting
  • import from basket, cherrytree, gnote, keepnote, knowit, mempad, notecase, tomboy, treepad lite, tuxcards, zim
