Issue #28 - 2012-02-06 - YAPC::EU CFP; TPF grant proposals; New book about one-liners

latest | archive | by Gabor Szabo

Wow, I don't know what happened, but this week we got so many posts. I had a really hard time to keep this newsletter at a reasonable size.

I saved some of the posts for later, in case next week, when the weather improves, the authors will go out instead of publishing articles.

Go, enjoy the articles...


Headlines

YAPC::EU::2012 Call for Speakers

YAPC::Europe will take place between 20-22 August, in Frankfurt. You are invited to submit talks already.


Announcements

Perl Data Language (PDL) 2.4.10 Release

.... This reminds me if we could marry Padre with PDL, that could be an interesting step towards providing an alternative to Matlab.

Brocade Execs Offer Look Under OpenScript Engine's Hood

I especially liked the part: 'Basically, we ported the Perl programming language to the ADX application processor so that you can use APIs to control application delivery with a script. This means you get all the Perl goodness that you know and love for writing custom scripts to read or write layer three to seven headers based on your particular application needs.'

2012Q1 Grant Proposals

Alberto Simões announced 3 grant proposals that were submitted to TPF. Please check them and comment on them.

Announcing the third e-book of Peteris Krumins 'Perl One-Liners Explained'

Articles

A Real Developer Challenge

Michael G Schwern describes how he thinks developers should be interview by potential employers. I am not sure if he talks from experience as an interviewer or as someone who is applying for a job. In either case interesting point.

HTML::ParseBrowser rides again

Neil Bowers describes the process of taking over maintenances of a CPAN module.


Testing

Why I Run Tests on Install

In response to an article by Jonathan Swartz arguing against running tests on installation, chromatic describes why he runs test and why he was looking for ways to improve the speed of testing. Being able to run the tests after installation would be nice and would be able to help in case we upgrade a dependency that breaks an already installed module.

Module releases and Test reports (A history of releases and perls)

Joseph Walton, author of XML::Writers takes the data from CPAN testers and shows some interesting graphs about the relation ship between the release dates of perl, XML::Writer and the respective test reports on CPAN Testers.


Refactoring

True + True == 2

'don't assume the author is an idiot'. An obvious refactoring and an educational post goes wrong. There is a certain relaxing feeling that even people like Schwern can make mistakes. Sometimes.

Perl: When DWIM Doesn't

An article by Douglas from Shutterstock about two surprising features of Perl that can easily trip programmers. Some interesting comments included.
