Port Your Code Around the World with m17n

Submitted by IdaAshley 2006-10-17 Unix 10 Comments

"To make Linux applications usable worldwide, with no inequity between Western dialects and the rest of the world's many languages, you must be able to deliver localized versions that input, store, retrieve, and render any language, no matter how complex. The multilingualization library, or m17n, provides a single internationalization solution for all languages on UNIX-like platforms."

Standardising UNIX Command-Line Tools

Submitted by IdaAshley 2006-08-22 Unix 3 Comments

"Examine methods for standardizing your interface to simplify movements between different UNIX systems. If you manage multiple UNIX systems, particularly in a heterogeneous environment, then the hardest task can be switching between the different environments and performing the different tasks while having to consider all of the differences between the systems. This article does not cover specific differences, but you'll look at ways that can provide compatible layers, or wrappers, to support a consistent environment."

Unix: An 800 Pound Gorilla No More?

Eugenia Loli 2006-08-08 Unix 11 Comments

Organizations adopting Linux might not abandon Unix entirely. NASA's Jet Propulsion Laboratory, for example, has migrated its e-mail system from Sun hardware and Solaris to HP servers and Red Hat Enterprise Linux. But even though the use of Linux on production servers is growing, the practice isn't yet the norm at the laboratory, said Douglas Hughes, a service engineer at JPL Information Services.

Retool Your Linux Skills for Commercial UNIX

Submitted by anonymous 2006-07-31 Unix 12 Comments

Examine how to best migrate your Linux skills to take advantage of AIX and Solaris. Linux is all the rage, but what if you have experience in Linux and need to apply it to a commercial UNIX environment? UNIX and Linux are similar, and many of the same principles exist; there is a shell, root is still all powerful, and many of the tools and applications are the same. This tutorial will show you how to cope and understand the nuances and differences.

Move an Entire File System on a Live Unix System

Eugenia Loli 2006-07-08 Unix 10 Comments

Copying a live file system can be risky, especially if there are open files. You should also be careful to ensure that you don't accidentally overwrite a partition, or existing files, with the files you are trying to copy. With some careful thought, you can effectively migrate files reliably to take advantage of more space, even on a live system.

Another Small UNIX Clone Written in c++

Submitted by david 2006-06-12 Unix 37 Comments

"UnixLite is a lightweight UNIX/Linux compatible operating system written in c++; it is open source and released under the GNU General Public License. The complete operating system is made up of a kernel and applications; just like Linux, UnixLite is only the kernel. The kernel itself is written from scratch and the biggest part is written in c++; however, the library used by UnixLite comes from uClibc and applicaitons running on UnixLite come from the GNU project."

Unix to Linux Porting

Eugenia Loli 2006-05-14 Unix No Comments

This chapter supplements currently available project management materials and books about application porting projects. Topics such as how to use formalized requirements processes, how to better communicate between software developers, and how to practice extreme project management are topics that modern-day project managers are already well informed of. However, because software development is not exactly the same as porting and migrating software, a gap exists in current publications—a gap that this chapter addresses.
