23 Years of Culture Hacking With Perl 99

Modern Perl writes "Larry Wall, the creator of Perl, reflects on Perl's history of hacking its culture, from subverting the reductionist culture of Unix to reinventing the ideas of programming language and culture in Perl 6 and the verbal aikido used to encourage honest detractors to become valuable contributors. Perl turned 23 years old last week, and Perl 6 is available."

Which Language To Learn? 897

LordStormes writes "I've been a Java/C++/PHP developer for about 6 years now. However, I'm seeing the jobs for these languages dry up, and Java in particular is worrisome with all the Oracle nonsense going on. I think it's time to pick up a new language or risk my skills fading into uselessness. I'm looking to do mostly Web-based back-end stuff. I've contemplated Perl, Python, Ruby, Erlang, Go, and several other languages, but I'll put it to you — what language makes the most sense now to get the jobs? I've deliberately omitted .NET — I have no desire to do the Microsoft languages."

The Coming War Over the Future of Java 583

snydeq writes "Fatal Exception's Neil McAllister writes about what could be the end of the Java Community Process as we know it. With the Apache Software Foundation declaring war on Oracle over Java, the next likely step would be a vote of no confidence in the JCP, which, if the ASF can convince enough members to follow suit, 'could effectively unravel the Java community as a whole,' McAllister writes, with educators, academics, and researchers having little incentive to remain loyal to an Oracle-controlled platform. 'Independent developers could face the toughest decisions of all. Even if the JCP dissolves, many developers will be left with few alternatives,' with .Net offering little advantage, and Perl, Python, and Ruby unable to match Java's performance. The dark horse? Google Go — a language Google might just fast-track in light of its patent suit with Oracle over Android." Reader Revorm adds related news that Oracle and Apple have announced the OpenJDK project for OS X.

JavaScript Cookbook Screenshot-sm 64

r3lody writes "I have enjoyed other cookbooks in the O'Reilly library of computer texts, so when I saw JavaScript Cookbook by Shelley Powers in the catalog, I jumped at it. The description mentioned that the book would cover HTML5 and ECMAScript 5, so I really wanted to learn the new capabilities of both. I did get to learn a lot, but I wonder if these new features are too new." Keep reading for the rest of Ray's review.

Gaming Foursquare With 9 Lines of Perl 84

caffeinemessiah writes "With the recent launch of Facebook Places, the rise to prominence of Foursquare and GoWalla, and articles in the New York Times about the increasing popularity of 'checking in' to locations using GPS-enabled mobile phones, a number of businesses are wondering how to reward frequent patrons. But exactly how susceptible are these 'location based services' to being abused? A researcher at the University of Illinois at Chicago shows how easily Foursquare can be gamed in 9 Perl statements, and invites readers to submit more succinct versions of the code to game the system." An anonymous reader contributes a link to a similar article about spoofing Facebook Places to create an alibi.

KDE 4.5 Released 302

An anonymous reader writes "KDE 4.5.0 has been released to the world. See the release announcement for details. Highlights include a Webkit browser rendering option for Konqueror, a new caching mechanism for a faster experience and a re-worked notification system. Another new feature is Perl bindings, in addition to Python, Ruby and JavaScript support. The Phonon multimedia library now integrates with PulseAudio. See this interview with KDE developer and spokesperson Sebastian Kugler on how KDE can continue to be innovative in the KDE4 age. Packages should be available for most Linux distributions in the coming days. More than 16000 bug fixes were committed since 4.4."

How Can an Old-School Coder Regain His Chops? 565

DonLab writes "I was a proficient software engineer in the 1980s, writing hundreds of thousands of lines of ALGOL, FORTRAN, COBOL, and Pascal programs, as well as working in 370 and 8080 assembly language & pre-relational DBMS systems. My hands-on programming career ended when I became a freelance analyst and designer, ultimately retiring young in the early '90s. Now I'd like to reenter the field, but I'm finding that I know nothing about today's post-C languages, programming tools, and computing environments. I wouldn't know where to start learning C++, PHP, Java, HTML5, or PERL, much less how to choose one over the other for a particular application. Can I be the only pre-GUI software designer or hobbyist searching for a way to update his skills for Windows, iOS, or Android?"

Perl 6, Early, With Rakudo Star 220

Perl 6 may have been "finally coming within reach" in 2004, but now it's even closer. Reader rnddim writes "The Perl 6 implementation Rakudo Star has been released today for 'early adopters.' This release of Rakudo is different from the normal monthly compiler releases in that it is bundled with a draft of a Perl 6 book, and several modules. It's not complete, and it's not as fast as it should be, but Rakudo in its current state is proving to be usable and useful. Rakudo Star releases will come monthly or as major features or bugfixes are made. It is available for download at github.com."

Hacking Vim 7.2 246

briancarper writes "Vim is an open-source text editor with a power and flexibility matched only by the steepness of its learning curve. As the author of this book states, 'Vim Can Do Everything' but configuring it to do so is sometimes daunting. Hacking Vim 7.2 aims to help the average Vimmer get the most out of customizing Vim, for fun and productivity." Read on for the rest of briancarper's review.

Something For (Almost) Every Developer 263

First up, reader martinjlogan sends along a tutorial for setting up a workable Erlang/OTP development environment on a Mac. Next, reader acid06 notes news of Perl 5.12, including what may be the first delivered fix for the Y2K38 bug. (Hit the Read More link below for some details on Perl's new release strategy.) "After two years of development, the new major version of Perl is now available. Notable new features are: better Unicode support, proper support for time after the Y2038 barrier, new APIs to allow developers to extend Perl with 'pluggable' keywords and syntax, warnings for deprecated features and more. From the linked post: You can get it from the CPAN right now or wait for a platform-specific release (such as Strawberry Perl for Windows)." Finally, from reader snydeq: "InfoWorld's Martin Heller provides an in-depth review of Visual Studio 2010 and finds Microsoft taking several large steps away from its legacy IDE code. 'Visual Studio 2010 is a major upgrade in functionality and capability from its predecessor. Developers, architects, and testers will all find areas where the new version makes their jobs easier. Despite the higher pricing for this version, most serious Microsoft-oriented shops will upgrade to Visual Studio 2010 and never look back,' Heller writes. Chief among the improvements are Microsoft's revamping the core editing and designer views to use WPF, its overhaul of IntelliSense and support for test-driven development, and its intelligent support for multiple versions of the .Net Framework."

Microsoft Bots Effectively DDoSing Perl CPAN Testers 332

at_slashdot writes "The Perl CPAN Testers have been suffering issues accessing their sites, databases and mirrors. According to a posting on the CPAN Testers' blog, the CPAN Testers' server has been being aggressively scanned by '20-30 bots every few seconds' in what they call 'a dedicated denial of service attack'; these bots 'completely ignore the rules specified in robots.txt.'" From the Heise story linked above: "The bots were identified by their IP addresses, including 65.55.207.x, 65.55.107.x and 65.55.106.x, as coming from Microsoft."

Helping Perl Packagers Package Perl 130

jamie writes "chromatic has a great post today on the conflict between OS distributions and CPAN's installations of perl modules, along with some suggestions for how to start resolving this maddening problem: '[Though Debian has] made plenty of CPAN distributions available as .debs, I have to configure my CPAN client myself, and it does not work with the system package manager. There's no reason it couldn't. Imagine that the system Perl 5 included in the default package... had a CPAN client configured appropriately. It has selected an appropriate mirror (or uses the redirector). It knows about installation paths. It understands how to use LWP...' The idea of providing guidelines to distros for how to safely package modules is a great one. Could modules request (a modified?) test suite be run after distro-installation? Could Module::Build help module authors and distro maintainers establish the rules somehow?"

The Perl 6 Advent Calendar 160

An anonymous reader writes "Larry Wall wasn't joking when he said that Perl 6 would be ready by Christmas. Perhaps not this Christmas, but that hasn't stopped a group of people (including head Rakudo developers Patrick Michaud and Jonathan Worthington) from putting together an Advent Calendar, featuring one cool Perl 6 feature every day until Christmas. Topics currently covered include how to get and build Rakudo (the most actively developed and progressed implementation of Perl 6) and the new Metaoperators. For those wondering when Perl 6 will be finished: Rakudo will be having its official 'production release' (dubbed Rakudo Star) April 2010."

Ultrasurf Easily Blocked, But So What? 74

Frequent Slashdot contributor Bennett Haselton writes "A simple experiment shows that it's easy to find the IP addresses used by the UltraSurf anti-censorship program, and block traffic to all of those IP addresses, effectively stopping UltraSurf from working. But this is not a fault of UltraSurf; rather, it demonstrates that an anti-censorship software program can be successful even if it's relatively trivial to block it." Read on for Bennett's analysis.

Interview With Brian Kernighan of AWK/AMPL Fame 117

Reader oranghutan brings us another in Computerworld's series of interviews with icons of the programming world, this one with Brian Kernighan, who helped popularize C with his book (co-written with the creator Dennis Ritchie) The C Programming Language, and contributed to the development of AWK and AMPL. In the past we've chewed over a few other interviews in this series, including those with Martin Odersky on Scala and Larry Wall on perl. "In this interview, Brian Kernighan shares his tips for up-and-coming programmers and his thoughts on Ruby, Perl, and Java. He also discusses whether the classic book The Practice of Programming, co-written with Rob Pike, needs an update. He highlights Bill and Melinda Gates as two people doing great things for the world enabled through computer science. Some quotes: 'A typical programmer today spends a lot of time just trying to figure out what methods to call from some giant package and probably needs some kind of IDE like Eclipse or XCode to fill in the gaps. There are more languages in regular use and programs are often distributed combinations of multiple languages. All of these facts complicate life, though it's possible to build quite amazing systems quickly when everything goes right.' 'Every language teaches you something, so learning a language is never wasted, especially if it's different in more than just syntactic trivia.'"

FBI Investigates Liberator of Court Records 445

eldavojohn writes "Federal court documents aren't free to the public, they cost $0.08/page through a system called PACER. During a period when the US Government Printing Office was trying out free access at a number of courthouses around the US, a 22-year-old programmer named Aaron Swartz installed a small PERL script at the 7th US Circuit Court of Appeals library in Chicago — a script that uploaded a public document every three seconds to Amazon's EC2 cloud computing service. Swartz then donated over 19 million documents to public.resource.org. That's when the FBI took interest in the programmer responsible for this effort and ran his name through government databases. How did he discover this? His FOIA was approved, of course, and he received the FBI's partially redacted report on himself. The public.resource.org database was later merged with that of the RECAP Firefox extension, which we discussed a couple of months back." Update: 10/06 18:22 GMT by KD: Timothy Lee pointed out that the summary as originally posted garbled the Swartz / RECAP connection. Improved now.

Perl 5.11.0 Released 235

jamie points out that Perl 5.11.0 was released yesterday, as well as a schedule for future 5.11.x releases, planned for the 20th of every month. Jesse Vincent encouraged testing of the new (development) version, saying, "If you write software in Perl, it is particularly important that you test your software against development releases. While we strive to maintain source compatibility with prior releases wherever possible, it is always possible that a well-intentioned change can have unexpected consequences. If you spot a change in a development release which breaks your code, it's much more likely that we will be able to fix it before the next stable release. If you only test your code against stable releases of Perl, it may not be possible to undo a backwards-incompatible change which breaks your code."
