latest | archive | by Gabor Szabo

Hi and welcome to the new subscribers!

It seems this was a very busy week. Lots of posts. Way too many to include all of them here.

We have also passed the 3,000 subscribers. I wrote about this and the post was submitted to Hacker News. This brought quite a number of new subscribers. For more details check the 'self promotion' section below.

Now to the interesting stuff:


Announcements

A pastebin with almost no user interface

Mike Doherty wrote WWW::Hashbang::Pastebin, a simple pastebin written in Dancer. I guess it could be nice to set it up within a company and start using it for showing code examples via the network.

Foswiki 1.1.5 released

Michael Daum announced the new release of the Perl based wiki. This includes both security fixes and other improvements.

Articles

Defending Against Its Dynamic Scope

chromatic writes about a nasty trap that one can fall in when using $_ in a construct that calls some other code that might change $_. It is especially a problem in map and grep where you have to use $_.

Discussion

Testing

Verifying MySQL behaviour with automated test suites and mytap

Cosimo Streppone did not write about Perl in this article but he is using mytap, the MySQL version of TAP, the Test Anything Protocol. It is very nice to see how Perl helps the quality of the Opera browser through testing MySQL.

Learning Perl with Testing

Instead of Test Driven Development, Nitish Bezzala suggests Test Driven Learning. I think this can be a good idea though one needs to think how to introduce it and how to make sure the test framework does not hide problems or introduces new ones.

Mock Objects Despoil Your Tests

While I agree with chromatic that too much mocking in tests is not healthy I am really not sure where does he get the idea that mocking is overused. The companies I visit never do mocking. OK, they usually don't do any testing and that's why they invite me and the only way to get some test up there is to mock half the universe. Or at least the external APIs. In any case, it would be interesting to check the level of mocking within CPAN.

Perl QA Hackathon

A late memoire from the Brazilian player called Breno G. de Oliveira (garu).

Perl - How to work offline?

Geistteufel sets up his environment to be able to work offline. Including having access to CPAN while on the road using Mini CPAN.
