Four articles about embedded Linux development, from Linux Journal's January issue, are available online. They respectively discuss GUI library choices, how multiprocessing is changing embedded computing, a volunteer-run project in Montreal to present local artists at multimedia kiosks, and porting Linux to a PowerPC-based softcore.

The four articles are listed below. Click each title to read the complete article at LinuxJournal.com:

• Choosing a GUI Library for Your Embedded Device, by Martin Hansen — This article examines the differences between Qtopia and Nano-X (formerly MicroWindows), and offers some advice about when to choose each.
• SMP and Embedded Real-Time, by Paul McKenney — This article argues that commodity multithreaded and multicore processors have corroded five time-honored truisms:
  1. Embedded systems are always uniprocessor systems
  2. Parallel programming is mind crushingly difficult
  3. Real time must be either hard or soft
  4. Parallel real-time programming is impossibly difficult
  5. There is no connection between real-time and enterprise systems

• The HAL Project, by Pascal Charest, Michael Lenczner, and Guillaume Marceau — This inspiring article describes how Montreal's Ile Sans Fil club of volunteer wireless hotspot instigators branched out into digital signage kiosks that render the creations of local artists, musicians, and film makers, at select hotspot locations.
• How to Port Linux When the Hardware Turns Soft, by David Lynch — This entertaining and well-written article describes one programmer's efforts to port Linux to a Pico E12, a tiny computer in a CompactFlash form factor that is powered by a PowerPC core running on an FPGA.
