Suppose you have a list of manga directories i.e folders with images that have numbers as names. Although applications like MComix can read such directories without any problem, you might feel like creating a proper comic book archive using these images. Here is what I do to convert these directories to cbz files.

Sometimes we like to watch cool starting and ends of videos (like the heart touching ending), but after a time those could become repetitive and boring. Also, if you are just starting to watch a series recommended by others, those extra 5 minutes could be saved to watch next video and progress quickly. In this tutorial, I wish to tackle that problem. Since I love mplayer/smplayer for playing most videos, I am not going to deviate from those lines. Therefore, I am going to use mpv (mpv is a fork of mplayer2 and MPlayer) for our purpose.
Transmission is a torrent client that comes pre-installed with most linux based operating systems like Ubuntu, Elementary OS, Linux Mint etc. However, in this post I am going to talk about transmission-remote, a command line variant of this popular torrent client. I have been using it for past 6 months, and I like it very much. With it I can control the client using terminal commands, using a web browser or “transmission remote” android or a gtk GUI applications. I also use different key bindings to control behaviors like pause the torrents, start them, or use alternate speeds. I also use other torrent clients for smaller download sessions, but transmission-remote is my default torrent client for most of my downloads. I use “transmission-remote-gtk” GUI tool for commands I don’t want to remember e.g creating labels (a label is an alias for specifying a download directory and you can have as many as you like), changing the queue size etc.
In this tutorial, I am going to talk about setting up emacs so that it will be easier for new users to get to their programming or editing tasks without much barrier.
If you don’t know emacs’s basic keys (at least the movement and editing keys), you need to keep a note of some of the most frequently used ones. You can copy the commands using some websites containing the basics (e.g http://mally.stanford.edu/~sr/computing/emacs.html) or use the list from “Movement” section below.
It is easier to use GUI tools to setup keyboard shortcuts, but sometimes you need to map certain keys for typical purpose (e.g swapping caps and esc when using vim). In this tutorial I will try to list different linux tools and scripts that you can use to do these tasks (you might have to install them from your distribution’s repository).
Ctags lets you tag your current code and header files. It supports many languages. With tagging, when you are writing code, you can quickly traverse to the declarations and definitions of functions and variables. Once you install ctags in your distribution issue following command to tag source code (after you know where the source code for the library or program you want to tag exists).
In this tutorial I will list some techniques to understand a basic Linux program. I will use a simple assembly program that uses nasm syntax. Common program format in Linux uses GNU assembler syntax. Therefore, this tutorial does not cover understanding that syntax (which I might do in future). Lets get started.
Most of the times volume in Linux is crisp and soothing. However there are times when you change the volume it collectively increases the PCM volume level and which in some cases can result in cracking sound. The problem is that after the PCM volume goes up it does not come down when lowering the volume level. In this tutorial I will discuss about a small fix that will help you set only one volume slider when increasing or decreasing system volume. In my case both Master and PCM can change the volume level of output sound. Therefore I would like to change only one of them while keeping another fixed.
This example can be used to setup a minimal Linux installation for any task. In this tutorial however I am going to use kernel development as an example. Since the process I have used in the past have been from sporadic sources, I wanted to consolidate the information for my own need. This tutorial is the result of that effort. So that next time if I feel like doing something kernel related, I don’t have to start over again.
We are going to setup a minimal ubuntu installation (no GUI) for kernel development. Install ubuntu minimal from this link. For this tutorial I will use Ubuntu 12.04 LTS version in virtualbox with 17 GB space. Make sure the architecture (32-bit, 64-bit) matches that supported by virtualbox. In virtualbox select at least 2 cpu and half of system RAM (keep everything under the green line). Since we are going to install necessary package later on, you don’t have to install any special packages during the installation. Skip the package installation step and complete the installation.
i3 is a tilling window manager. It is dynamic, fast, and an addictive environment. I have been using it for last 6 months. Once the initial hiccup is dealt with it becomes natural to you and the way you do computing. In this tutorial I will try to explain the basics and help you getting started with i3.
