Introduction
This guide will help you to install OpenGEU and every other Ubuntu based linux distribution on your Macbook (either “normal” or pro). Even Ubuntu will work with this how-to.
The tutorial is aimed on how to succesfully partition the hard disk and to correctly boot the distribution. For a better post-install configuration I suggest you to follow the Ubuntu Wiki.
This tutorial is also posted on the OpenGEU Wiki

Time for a review. Thanks to the always useful DistroWatch.com service, I discovered a new Gnu/Linux distribution, called gOS. gOS stands for Good Os, born in 2007 in California. The version I’m reviewing is the so-called “gOS 3 ‘Gadgets’”, their third release. gOS 3 Gadgets BETA is based on Ubuntu 8.04.1, and the final release is to be expected in the next 1-2 months.
This distribution is built around Goggle apps and services, comes with Google Gadgets for Linux pre-installed, as well other nice programs, like Google Picasa, Wine, Mozilla Prism for Google web applications and Wbar as launch bar. I’ve never heard about this bar, it’s very quick and light. Good choice! The distro also includes proprietary codecs for multimedia content.

Misc
After about 5 months of separation from my preferred operating system, the discontent brought by Mac Os X led me to a re-born love with Gnu/Linux.
I Installed Gentoo (~x86, not x86) on my MacBook, following some articles found on the Gentoo wiki and on Ubuntu wiki.
The result is the following:
Clean Desktop
Some things opened: Gnome Menu, Gnome Terminal, Nautilus, Scite
Features:
- Gnome 2.22.2
- MurrinaGilouche + Elementary Metacity (link - link)
- black-white 2 Gloss Icons (link)
- Screenlets [RingSensors] (link)
- A wallpaper included in Gnome, still looking for the perfect one
Let’s have some fun with Gnu/Linux…again!
Immaginate questo pensiero contornato da mille bestemmie..
Perchè uno straccio di programma in C che usa si e no 10 syscalls e un signal handler (tutto standard), compilato con gcc 4.0.1 sotto Mac Os X Leopard, quindi certificato Unix 03, e perfettamente funzionante…NON FUNZIONI su Gnu/Linux 2.6.18 + gcc 4.1.2 e Gnu/Linux 2.6.24 + gcc 4.3.1?
Segmentation Fault a manetta..e si che mi sembrava un po’ permissivo gcc 4.0.1 su Mac os X quando lavoravo con puntatori a stringhe e liste linkate..
Caro Gnu/Linux, sto tornando.

My Life
BD-shell (a.k.a. bdsh) is a tiny Unix shell written in C. It’s a project required for the Operating System Course at my University.
It is written using a clean coding style, following xP coding standard philosophy.
Version 1.0 is the release that satisfies all the course requirements!

Cool Features
- Lightweight
- Implements real Job Control
- Clear and understandable code, ideal for Academic (and personal) studies
- Makes use of various system calls, signals, signal handlers, user input handling, data structures implementation
- Free Software!
Cool Features NOT present (but may be in future)
- No command history present
- No command/filename auto completion
- No wildcars
- No command piping, just a single command can be launched at a time
- Put everything else here.
Requirements for 1.0.0 (click the arrow)
These are the requirements asked by the teaching professor. The complete project description page is located at
http://www.inf.unibz.it/~david/os/project.html
The shell must be able to do the following:
- to read commands from standard input and execute them in a loop until a
built-in command exit is issued (we call these processes the foreground processes; there is always at most one of these at any particular time);
- be able to redirect the standard input and output of commands by prefixing them with built-in commands in file and out file;
- be able to terminate (involuntarily) the foreground process when user presses ^C and return back to the mini-shell;
- be able to interrupt the foreground process temporarily, when user presses ^Z, returning to the mini-shell;
- be able to execute any number of processes in background (i.e., in parallel with the foreground process), including in particular, the ability to start another process while a process has been temporarily suspended;
- inform the user when the background process finishes or is
waiting for an input from the terminal;
- be able to inform the user what commands are executing in the background by issuing the built-in command jobs, this should include information about the state of the process (i.e., suspended, background, waiting for input, etc.) and about what file(s) is the background process using for standard input and output);
- be able to terminate involuntarily a background processes by issuing the built-in command kill job-number.
- to be able to resume a process or to make a background process into the foreground process (i.e., the one that currently interacts with the terminal) by issuing the fg job-number command.
- 2008-09-14 - version 1.0.0.
- fixed synchronization bug in putJobBackground() that made not notify background processes requesting input (in some situations)
Known Bugs:
- Lots of! I consider bdsh-1.0.0 stable because it covers ALL requirements of the course and does them whell on various Unix systems. So it works, but commands like “in non_existent_file cat” won’t work and will crash it!
What will be next?
- I don’t know. I may consider a 1.0.1 release to fix future bugs. I may also think to add cool features to make the shell complete. I hope I will have the time for it. You can also do it by yourself and send me the code
Old Releases (click the arrow)
- 2008-09-13 - version 1.0.0 Release Candidate 2.

Characteristics:
- First beta release of the final version
- Every requirement has been covered
- Real Job-Control implemented
- About every function of bdsh.c has been rewritten
- New source directory layout, very clean
- Some documentation and makefile
- IMPORTANT! this has to be considered a bug hunting release! Please report me any bugs
-
2008-06-05 - version 0.7.1, corrects the linked list bug of version 0.7.0
- 2008-05-09 - version 0.7.0.
UPDATE 2008-06-05: there is a bug in the list handling, the shell crashes when using the standard input redirection. Please download version 0.7.1, which corrects the problem.
Characteristics:
- Cleaner code!
- Lots of bugs fixed!
- reads commands from standard input and executes them in a loop until a built-in command exit is issued
- redirects STDIN and STDOUT of commands by prefixing them with built-in commands in file and out file
- terminates (involuntarily) the foreground process when user presses ^C and return back to the shell
- executes any number of processes in background (i.e., in parallel with the foreground process)
- informs the user when the background process finishes
- informs the user what commands are executing in the background by issuing the built-in command jobs
- terminates involuntarily a background processes by issuing the built-in command kill job-number.
- Due to a lots of compatibility issues with Gnu/Linux (the shell has been developed under Mac Os X), the final released has been delayed to mid-September. Sorry for this, I encountered so many problems the day before project presentation, that I decided to present it during the next exam session. I switched back to Gnu/Linux, too
-
Final release is scheduled on 2008-06-26, as the project deadline is 2008-06-25. The release will
satisfy all the requirements, and as addition:
- Execution system totally rewritten (e.g. one single short function that handles everything)
- A Job Control will be implemented
- Processes in foreground will really be in foreground, there are a lot of things that we did not learn during the course, like tcsetpgrp()
- Some functions in utils.h will be deleted and optimized
- Cleaner and clearer code!
- 2008-04-21 - version 0.0.1
Characteristics:
-
Modular code, divided in 3 files: bdsh.c, utils.h, headers.h
-
Clean user input from a char buffer to an array of strings
-
Built-in commands: exit (exits from the shell), cd (changes directory), in <filename> command (redirects STDIN of command from <filename>), out <filename> command (redirects STDOUT of command to <filename>)
-
Makes use of fork() to read commands from standard input and execute them
