Two hobbies are prevalent in my house: Lionel trains and Linux computers. The train layout isn’t a permanent fixture; it gets set up a couple of times a year – usually around Christmas – but it’s been known to appear during the summer as well. The last time it appeared, I added a Linux computer to control the setup. Although I still run the trains with traditional throttles, I let the computer play with the rest.
Rather than write one massive control program, I decided to split the design into single-purpose modules that run independently (Figure 1). Each module performs a single task in either the input, output, or control categories. Any given input or output module corresponds directly to a specific piece of hardware. Control modules don’t have hardware equivalents but instead provide the logic that links the inputs and outputs. Any number of modules can be run simultaneously.
The modules are written in Python and use mmap to communicate among themselves. The files inputs.txt, which represents the current state of the railroad’s sensors, and outputs.txt, which has the requested state for the relays or LEDs that activate working accessories, are memory-mapped files. They are both initialized to a single line of 100 zeros.
Open source version of LiveCode is now available for developing apps, games, and utilities for all major platforms.
Games vendor Valve has ported its Steam platform to Linux, thus shifting the free platform into the focus of serious gamers. The manufacturer recently invited some users to participate in a closed beta phase. I took a look at the trial version of the Steam client, which still has some quirks.
Officially, Valve only supports Ubuntu and other Debian-based distributions, so I used a recent version of Ubuntu (12.10 “Quantal Quetzal”) in my tests. With some tinkering, you can talk Steam into cooperating with other distributions. The “Valve’s Strategy” box explains why the company uses Linux as a platform.
Although my position demands that I maintain strict impartiality, I must admit that I have always secretly cheered for Fedora. I’m not sure why – I just like it. The people I meet from the Fedora project seem really smart and articulate. Fedora always seems to work when I try it – which is admittedly less remarkable for a Linux than it used to be. Fedora is also the inheritor of the great Red Hat Linux legacy – the old Red Hat Linux I mean: the one they used to give away.
Linux Mint 14 “Nadia”
Linux Mint is a wildly popular Ubuntu-based desktop Linux with an emphasis on simplicity. Along with a strong assortment of open source applications and utilities, Mint takes pains to provide proprietary drivers and other helper tools for seamless-as-possible operations. The Mint 14 release features a new Windows Quick-list app for managing windows across multiple workspaces, as well as Alt+Tab window-switcher virtualization and a handy notification tool. Also debuting with this release is the new Nemo file browser, a fork of Gnome’s Nautilus file manager based on the Nautilus 3.4 codebase.
Here’s the situation: You want to store a large file on a USB memory stick, but the attempt fails even though you have enough space. In this case, you have very likely hit the limits of the filesystem on the medium you are using. The possible causes are a full File Allocation Table (FAT) – the directory for the disk contents – or reaching the maximum number of blocks per file.
For compatibility reasons, many manufacturers supply your media with the VFAT or FAT32 filesystems, and you might not notice for a long time that they limit the size of a file. Both can store files up to a maximum of around 4GB; however, you can transport larger files from one computer to another in other ways.
As a special bonus, this month’s DVD also comes with the Knoppix 7.0.4 Live Linux distro, a favorite tool of system rescue specialists and other IT professionals. Boot Knoppix from your DVD drive and use this disc to explore the Knoppix rescue tricks described in this issue.
