o UNICODE is necessary for international web development, but poses a few problems, writesReuven M Lerner (reuven@lerner.co.il>

o UNSING THE input subsystem, Part II. No matter how many buttons an input device has or how many kinds of events it can generate, you can now work with it from userspace.

o CHATTING UP the chef: introducing two chat servers, geektalkd and Shadowlands Forum, and a fine Jabber instant-messaging client, by Marcel Gagne.

o rsync, PART I: rsync makes efficient use of the network by only transferring the parts of files that are different from one host to the next. Here's how to use it securely.

o LINUX SIGNALS for the application programmer: Signals are a fundamental method for interprocess communication and are used in everything from network servers to media players. Here's how you can use them in your applications, explains Dr B Thangaraju (who has a PhD in Physics and worked as research associate in the IISc. He is presently manager at Talent Transformation, Wipro Technologies, India. His current area of research, study and knowledge dissemination are Linux kernel, device drivers and real-time Linux.)

o ORIGINAL and ultimate communities: Will the Web ever support on-line communities like the best of what we had in the old days, asks Doc Searls.

o AN INTRODUCTION to the Spambayes Project. A trainable system that works with your current e-mail system to catch and filter junk mail. Download the software from sf.net/projects/spambayes

o A STATISTICAL APPROACH to the spam problem. Using Bayesian statistics to detect an e-mail's spamminess, by Gary Robinson.

o BUILDING WITH BLOGS: The category is hot and huge but still new. Here's a look at your choices. By Doc Searls and David Sifry.

o eVote ADDS ELECTIONS to mailing lists.

o E-MAIL EVERYWHERE from anywhere. Whether you want to connect your home system to the Web while you're at work or need to view e-mail attachments on a remote system, the LJ website (www.linuxjournal.com) has an article about it, says Heather Mead.

o LINUX BUYERS GUIDE (www.linuxjournal.com/bg) will allow users to search through thousands of GNU/Linux-related listings and companies, on one site.
