Many people ask for Camtasia Studio replacement in Linux. Actually there are many solutions in Linux such as RecordMyDesktop, Vokoscreen, Istanbul, Kazam, ffmpeg, even VLC. But among the available softwares, I choose SimpleScreenRecorder. It is because (according to my experience) I get the best compromise between quality and perfomance. I ever tried many of them but my system crashes many time because of the resource requirement. Here is my simple explanation on how to use SimpleScreenRecorder and Keymon to create video tutorial (screencast, screen record). I assumed you have installed both of them.

In scientific or official documents, you usually need to insert footnote. It is a small text addition in the bottom of page with a corresponding reference number in the main text. You can insert footnote in LibreOffice Writer by menu Insert > Footnote/Endnote.


I will show you how to easily create and modify columns in Writer. I will give you direct examples and explanations. Then you can follow it and apply it on your document.

Types of Columns



Firstly, you should know the types of columns. There are generally 2 types of columns based on the vertical position. First, partial column in single page. It means some parts are columned and other parts are not in a single page. Second, whole parts columned. It means no part is different. See picture below to differ it.


If you somehow find your Linux system crashes, do not kill (pressing power button) the computer directly. Such hard kill may broke your hard disk drive or corrupt your data. When you are facing system hang or crash or freeze, you can use Linux special shortcut keys to restart or shutdown safely. It is actually something called Linux Magic SysRq Keys[1]. Do not use these shortcut keys unless you need it urgently. And you can use these shortcut keys on another Linux distro. 

Restart



Alt + Printscreen + REISUB

It means hold the Alt and printscreen by right hand, then press R + E + I + S + U + B by left hand. Respectively, I show below explanation for each key.

  1. R: take control the keyboard from X Server
  2. E: send SIGTERM signal to all processess (prepare them to death[2]) except init
  3. I: send SIGKILL signal to all processess (kill them[3]) except init
  4. S: sync all mounted filesystem
  5. U: unmount all filesystem and automatically sync them
  6. B: reboot without unmounting and syncing filesystem
  7. O: shutdown

I am using Telegram Desktop 0.8. I am connecting to the internet via an authenticated proxy. Telegram will not connect with such connection. How to configure it properly? Just open Settings > scroll down > Advanced > Connection type. 

Find The Configuration

My LibreOffice Writer 3.5.7 crashes every I click menu Tools > Bibliography Database. So I can not open it. After searching, I find that default LibreOffice in Ubuntu 12.04 (which I am currently using) was missing LibreOffice Base. Bibliography Database needs LibreOffice Base so it crashes on my Ubuntu. Do you experience same crashes in your Ubuntu? Then just install Libreoffice Base. Below you can choose installing whether by using Terminal or GUI.

Result



Bibliography Database Works


If you are writing scientific paper or such documents, you need table of figures. Actually it is same with table of contents. LibreOffice calls it Illustration Index. We will show you an example.

Currently I am resuming my old curiosity about page layout design. I used Scribus 5 years ago. At that time, I feel it was difficult to create even just a page layout in Scribus. Now I know, that difficulty was caused of lack in page layout knowledge. At 2015, Scribus reached 1.4.5 version (stable). Scribus has more resources now compared to 5 years ago. Especially its Wiki[1] plus Flossmanuals[2]. I created some layout designs at few days ago. I learnt a few things I was missing 5 years ago. Below you will see some tips from me to design a layout with Scribus to avoid difficulties (time consumption etc.). Remember that it is just basic and somehow subjective (according only to my experience).
