xmotd: Writing Free Software

One programmer's experience developing freely available software for Linux.
Conclusions

“A work of art is never complete; the artist merely abandons it.” --Unknown

Three years (and 14 releases) later, I thought xmotd was approaching completion; i.e., every option that could possibly have been added had been. Since December 1996, however, more suggestions (which will be incorporated into version 1.15 of xmotd) were submitted, including one for running the HTML version within an Intranet and having it spawn a web browser when an URL was clicked. I should note that xmotd gained popularity when it began supporting HTML. (See Figure 3.)

Figure 3. HTML Version of xmotd

My advice to eager developers is, first, not to begin writing software without ascertaining whether a similar package exists (web space can be effortlessly searched these days); if it exists, consider extending it rather than starting from scratch. Second, write the software with full intent of incorporating user suggestions (don't ignore your users) and bug fixes following the first release (version 1.0 is never the last release). Finally, write software that keeps pace with advances in technology (e.g., Java) or face obsolescence. People will begin to use software only if it satisfies their needs and will continue using it only if it evolves to accommodate their changing needs. Persevere until the day you write software that receives the world-wide acclaim we all dream about.

  1. The significance of the short coding time is that I use a template file, which contains a skeleton X program including the necessary include statements, application defaults, accelerator and X resource structures, a main() function with XtAppInitialize() calls and more.

  2. eX refers to the defunct X Consortium (disbanded in December 1996).

  3. The Emacs editor embodies this principle to perfection: every character on the keyboard can be re-mapped.

  4. -usedomainnames may be used at sites where home directories are shared (NFS mounted) across various domains and the message of the day applies across the whole network.

  5. Insanely popular software like the Emacs editor, GNU/Linux, the GNU C compiler, Perl and the X Window System does not need a home-page—its popularity makes it ubiquitous. It will be archived on any major ftp site.

His definition of fun includes hacking X and Java; listening to music (composed before 1800 and played on period instruments, in particular); reading unusually good books and generally doing anything creative.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
