Practical Perl Tools: Constant as the Northern $*
;login: Enters a New Phase of Its Evolution
For over 20 years, ;login: has been a print magazine with a digital version; in the two decades previous, it was USENIX’s newsletter, UNIX News. Since its inception 45 years ago, it has served as a medium through which the USENIX community learns about useful tools, research, and events from one another. Beginning in 2021, ;login: will no longer be the formally published print magazine as we’ve known it most recently, but rather reimagined as a digital publication with increased opportunities for interactivity among authors and readers.
Since USENIX became an open access publisher of papers in 2008, ;login: has remained our only content behind a membership paywall. In keeping with our commitment to open access, all ;login: content will be open to everyone when we make this change. However, only USENIX members at the sustainer level or higher, as well as student members, will have exclusive access to the interactivity options. Rik Farrow, the current editor of the magazine, will continue to provide leadership for the overall content offered in ;login:, which will be released via our website on a regular basis throughout the year.
As we plan to launch this new format, we are forming an editorial committee of volunteers from throughout the USENIX community to curate content, meaning that this will be a formally peer-reviewed publication. This new model will increase opportunities for the community to contribute to ;login: and engage with its content. In addition to written articles, we are open to other ideas of what you might want to experience.
The bad Perl wordplay in the title can mean only one thing: We have another column about programming in the Perl language underway. This issue’s column is inspired and derived from an article I stumbled on by Neil Bowers. Back in 2012 he wrote an article on 21 different modules for defining constants in Perl. The original is at http://neilb.org/reviews/constants.html. If reading my take on his research gets you interested in the subject, do be sure to seek out his article. One other thing I should mention before we discuss his work: He’s clearly cooler than I will ever be. When he encountered some bugs in one of the modules he reviewed, he “took over maintenance of the module and released a new version which addresses all known issues.” Now that’s thorough!
