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
  • export to cherrytree file of a selection / node / node and subnodes / the whole tree
  • password protection (using http://www.7-zip.org/)
  • tree nodes drag and drop

Install CherryTree on Ubuntu:

CherryTree is available in Ubuntu’s universe repository since Ubuntu 12.04 Precise. Search for and install it from Ubuntu Software Center.

For the latest version, press Ctrl+Alt+T to open terminal and run below commands:

sudo add-apt-repository ppa:vincent-c/cherrytree

How to Get Better Performance on Old Ubuntu Laptop

Last updated: July 20, 2013


This simple and brief tutorial is going to show you how to speed up your snail-slow laptop by tweaking your Ubuntu system. There’re some tools and apps to improve the overall performance of an Ubuntu powered machine. They are really helpful if you have an old machine with the hardware that are out of date.

Improve Performance with ZRAM on low RAM machines:

ZRAM is a is a module of the Linux kernel that creates a RAM based block device which acts as a swap disk, but is compressed and stored in memory instead of swap disk (which is slow), allowing very fast I/O and increasing the amount of memory available before the system starts swapping to disk.

This gives amazing performance improvements on systems with low RAM. Especially netbooks! Search for and install zram-config from Ubuntu Software Center. Then restart, zram is running silently as a background process.

Speed up application loading time by using Preload

Preload is nice little application that could make your linux system a lot faster. Preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

Preload is available by default in Ubuntu Software Center. Just search for and install it, then it’ll run silently as a background process. If you want to further tweak Preload, conf file is available at /etc/preload.conf.

Speed up Unity desktop by disable graphics effect:

Unity 2D has been dropped since Ubuntu 12.04, it’s no longer available in higher editions. If you’re using Ubuntu with Unity as its desktop environment, you can turn off the graphics effect to get a better experience.

To do so, create file .xprofile on user Home folder and open it with text editor (You may check if it already exist by press Ctrl+H to view hidden files). Add below line and save it:

export UNITY_LOW_GFX_MODE=1

That’s it. Hope this tutorial may help you!
