On the Web - The Language Battle
Some arguments never seem to lose their popularity. Perhaps the new rule should be never talk about religion, sex, politics or programming languages—but how boring would that be? The publication of “Interview with Bjarne Stroustrup”, the creator of C++ (www.linuxjournal.com/article/7099), on the Linux Journal Web site, set off another battle in the ongoing programming language flame war. In the interview, Stroustrup discusses some of the history behind C++ as well as its evolution. The comment section, however, turned into an argument on whether C++ is a bad language or whether programmers merely use it incorrectly.
One of Stroustrup's rather sensible observations is people should use the best language for the task at hand. So with that in mind, this month we offer a recap of some language-specific articles available on the LJ Web site. With the increasing popularity of LDAP servers, it's good to have several management options available. In “An Introduction to perl-ldap” (www.linuxjournal.com/article/7086), Paul Dwerryhouse discusses how to use the Net::LDAP Perl module to “enable easy access to the data contained in LDAP directories from Perl scripts”. He then walks users through installing the module and demonstrates how to add, search for and modify entries.
If LDAP is your thing but Perl is not, check out “LDAP Programming in Python” (www.linuxjournal.com/article/6988) where Ryan Kulla explains how to use the python-ldap package with its object-oriented client API to work with LDAP directories. Kulla's goal is to “get you ready to write your own programs to automate the querying process of LDAP servers”. His example program demonstrates some of the basics that you can extend and explore on your own.
Continuing with Python, in “Host-Hopping Scripts in Python” (www.linuxjournal.com/article/6730), Mark Nielsen explains “how and why I used SSH, Python and Expect to transfer Weblogs to a central computer for processing”. A good example of using the right tools for the task, Mark's project also took advantage of tools already available on the network computers. The scripts included in the article show you exactly how he combined all the elements to gather together the systemwide Weblogs.
Not quite as volatile as the interview with Stroustrup, Aleksey Dolya's “Interview with Brian Kernighan” (www.linuxjournal.com/article/7035) explores some of the history behind the AWK programming language. The two also discuss C, how UNIX got its name, the early days of Bell Labs and teaching the next generation of IT workers.
If your personal favorite languages aren't mentioned here, do a search for them on the LJ site. We also have articles about working with Ruby, Objective-C, Java and others. And, be sure to check the Linux Journal Web site often; new articles are added daily.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
