N52te-only input and typing.

N52te keypad may be used as a full substitute for keyboard and mouse. With covered ~60% of a Windows-laptop keyboard, it’s possible to boot, change BIOS and boot-loader setting, log-in and manipulate PC. The layout bellow covers typing and simple scripting. In addition, an on-screen virtual keyboard may help to cover 100% of input.
The DPad in Blue mode uses a macros and OS’s ability to change an interpretation of the numeric pad (Num Lock) , to work as a mouse:
The Scroll Wheel up, down and middle-click changes Green, Blue and Red modes correspondingly. In other modes DPad helps to navigate:
After reconfiguration, N52te works in any operating system and does not require any additional software.

Direct to a disk drive system installation.

If there is a computer with no input/output devices. One of the solutions is a direct software installation to its disk drive. And a subsequent configuration of the remote access with help of a virtual machine (QEMU).

The examples below are for Windows workstation against two target systems: x86 (Ubuntu) and ARM (Raspberry Pi).

1. Get a installation media with a operating system for the target computer. In this particular example: Ubuntu server iso file and Rapbian wheezy image;

2. Download and install QEMU;

3. Get out the disk drive from the server and/or SD card from the Rpi.

4. Connect the disk drive to your working station. (SATA to USB converter is needed or a SD card reader in Rpi case);

5. Prepare (format/erase) the disk drive (a console way):

6. Find out a disk device number (DeviceID):


7. Start QEMU and install the operating system.
Script for x86 Ubuntu:

Where “\\.\PHYSICALDRIVE1” is a path obtained on the previous step.
Script for Raspberry Pi:

8. Configure and check a remote control to the emulated target operating system.
e.g. Add this to the start script to test a ssh access through 10022 port:
-redir tcp:10022::22

9. Insert your disk drive in the target system. It will take some time to boot and to autotune all new hardware during the first start.

How to save a website to an ebook file

To make an epub (or bunch other formats) from any website, firstly it should be saved locally:

Next, install Calibre from the repository:

Or download from its website.

Add the site structure to the calibre’s library by pointing on the index.html file or any other entrance point. Calibre’ll process it and compress in a single zip file. This file can be found in calibre’s library. Convert this zip file to epub by clicking on the “Convert books” button in main menu.

Or type in the terminal:

(ebook-convert is a part of Calibre utility)

An obtained epub file will be readable but will also contain some formatting errors. To fix them manually, rename epub to zip and edit a corresponding html/css/xml file. The contents list is usually located in a ncx file.

For example “GRUB4DOS Guide” from boot-land.net.

Several monitors with a linux laptop.

To use several monitors on different ports simultaneously, type in the terminal:

xrandr –output LVDS –off –output HDMI-0 –auto –output VGA-0 –auto –right-of HDMI-0.

In case of gnome UI.

Check if auto config is turned off:

gksu gconf-editor

branch /apps/gnome-settings-daemon/plugins/xrandrgconf-xrandr

Active‘s checkbox should be unchecked.
