Use sddm display manager with custom lock screen to replace gdm

Introduction

In Linux, I like to experiment with different user interfaces for the desktop experience. However, sometimes, certain components become blockade for enabling such environments. In the end, either I have to completely give up on the application, or live up with half baked application. One such component happens to be the display manager.

Create an offline personal wiki to organize your work

Introduction

There are times where you need to showcase your work. Public blogging websites are very good for that, but there are times when you may want to organize your work (say while you are learning) that you don’t want to share with others. E.g., You might be reading a new book about a programming language. There will be a lot of new concepts that you might not have heard before, and similarly there will be a lot of repeating concepts that you are familiar with. Therefore, you may want to only make notes of the new concepts, while trimming down already familiar concepts. Personal offline wiki is a great place to keep track of these kinds of work. With the help of links, text formatting, images, videos you can organize your work, so that it becomes a great learning resource for your personal use, that you can re-visit whenever you need to review the material. In this tutorial, I want to encourage you to install a wiki software (I will be showing few features of dokuwiki as an example, but you can install any) to manage your personal work on your own computer.

A fun way to read list using notifications

You may want to build your vocabulary on some domain specific words e.g languages, definitions etc. However, you get bored (get nowhere) if you sit there and start reading the whole list.

Simplify opening a new application in a new workspace in i3-wm

We often use i3-msg to open applications in new workspaces. However to type all the name of our custom workspaces is tiresome. I created a simple (very simple) script to use just the number to specify the workspace and open the application in that workspace. This is a python script, which you can put inside a bin directory and execute it with the number of the workspace and the application you want to execute in that workspace. For this to work, change the custom workspace names that matches the names you have defined for your workspaces in i3. Save the following file as i3openit.sh.

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.

Using mpv to escape start and end of videos (like in anime, tv shows etc)

Introduction

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.

Using Transmission Remote as your default bittorrent client

Introduction

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.
