More about Motor

What is motor?

Motor is an IDE for Linux that works in the console and provides the developer with a useful mcedit-like editor, front-ends to the compiler, linker, debugger (gdb), concurrent version system (cvs), ctags, rpm, automake/autoconf and other useful things. It can also generate distribution packages in any format. Almost everything is done with templates, so any kind of language or distribution can be easily added.

Chip with the BLIP

BLIP consists of a computer system with a built-in two-way radio, which transfers information to and fro. This facilitates the BLIP to create a wireless LAN that the user can easily access via Bluetooth mobile enabled device. BLIP comprises of a 32-bit reduced instruction set computer (RISC) CPU chip. It runs on an embedded form of Linux operating system developed by Linux specialists. The entire pattern of this device in terms of hardware and software is:


CPU: ARM7 TDMI based 32-bit RISC; 22.5 MHz clock rate

Introduction to Linux kernel modules

Linux operates in two modes--the Kernel mode (kernel space) and the User mode (user space). The kernel works in the highest level (also called supervisor mode) where it has all the authority, while the applications work in the lowest level where direct access to hardware and memory are prohibited. Keeping in line with the traditional Unix philosophy, Linux transfers the execution from user space to the kernel space through system calls and the hardware interrupts. The Kernel code executing the system call works in the context of the process, which invokes the system call.

Ext2- Part II: Inside the bonnet

A file system usually comprises of blocks of data. A typical filesystem volume starts with a `Super Block’, which has all information regarding used and unused blocks as well as availability and location of various inodes. Only the superuser can access super block.


DNS Tutorial

In Linux, the networking related services could be set up in three different ways:

1) /etc/hosts to /etc/hosts mapping based networking

2) DNS based networking

3) NIS/NIS+ based networking which in turn can take the help of DNS or /etc/hosts file

For network-based services the actual network daemon reads some file for communication.

The first file that it reads is /etc/host.conf. Over here one may generally find two lines as

Order hosts, bind, Nis

The Second Extended File System - An introduction

This file system, which draws its inspiration mainly from the Minix file system of the older days written by Andrew Tanenbaum, was the only file system that was available with a free operating system called “Minix”. It was later modified to be used with the Linux system and was called the Extended File System. The Linux file system being used now, called ext2 (Second Extended File System), is a newer version of the Extended file system that also supports the Access Control Lists (ACL).

I want that Linux device!

AGENDA VR3 PORTABLE PC Agenda Computing Inc, a California-based company has launched a full function PDA, codenamed VR3, running on embedded Linux. The Developer Edition, priced at $249, measures 4.5"x3.0"x0.8" and weighs 4 oz. It comes equipped with a 66MHz 32 Bit NEC VR4181 MIPS processor, 8 MB of RAM and 16 MB of flash storage. It has a 240x160 pixel monochrome LCD touch screen display with 16-level gray scale and a viewable area of 2" x 2¼".

Not just on your desktop

Indrema L600 game console The computer gaming industry is a multi-billion dollar one with the likes of Sony, Nintendo, Sega and Microsoft. Competing with them is a small company called Indrema promoting its new video game console powered by Linux. What makes Indrema unique is the fact that when launched this spring, Indrema L600 will be the first Linux-based game console. The fact that such a product is powered by Linux holds big promises for open source operating systems, which is what Linux is.

The Linux filesystem explained

For starters, there is only a single hierarchal directory structure.

Everything starts from the root directory, represented by '/', and then

expands into sub-directories. Where DOS/Windows had various partitions and

then directories under those partitions, Linux places all the partitions

under the root directory by 'mounting' them under specific directories.

Closest to root under Windows would be c:\.

Under Windows, the various partitions are detected at boot and assigned a

drive letter. Under Linux, unless you mount a partition or a device, the

Somebody stop me!

Word had been going around that the special effects for

Titanic were made on a Linux cluster. In spite of this and

all the spectacular stories we hear about Linux, I still

couldn't see Jim Carrey yelling "Somebody stop me" on my

machine. Well, this is not true anymore. Now, not only can I

listen to Jim Carrey, I can also hear the dinosaurs stomping

in my backyard! Video is very much alive and kicking on Linux.

This article is a look at the video libraries and players

available on Linux.
