I already knew about git-achievements, but earlier this week I was showen Unit Testing Achievements. My first thought after seeing it was: “cool, I want to port that to Smolder!”. My second thought was: “hey, if we can do it for Git, and for testing, why not for Perl itself?” Surely it wouldn’t be too hard to harness its power for a little bit of fun? Indeed, it wasn’t…Have a look!
This blog entry is based on true events. Only the pattern has been modified to protected the innocent.
In a turn of events so monumental that it can only possibly be a sign that Ragnarok is nigh upon us, an early adopter implementation of Perl 6 has been released. The number of blog entries that it generated is, as one might expect, quite massive. But most important is, the downloads — both for Unix and Windows — are available on Github. Don’t lose any time! Go, download, compile, and get a taste of what the new kid on the block has to offer.
I’ve spent over a decade managing various production systems. After spending so much time with systems that are mostly not working as they should, one develops certain outlook on life. Like the deep belief that the only way to keep civilization functioning is by taking backups and testing them. Recently I had few discussions with developers, and it turned out that ideas that I consider trivial can be viewed as deeply insightful by someone with different experience.
Larry Wall gave another of his unique keynote addresses at the first day of YAPCEU 2010 here in sunny Pisa (yes the place with the tower) This year was a little diversion from his usual pattern as Larry was assisted by his better half and his demon seed. Larry told us as a language designer his life is one of siting on the fence, not making up his mind until that one little voice in one ear (his better half) and that other little voice in the other ear (his demon seed) work it out somehow.
The first non-development version of XML::XSS has been released on CPAN. The big delta since the last blog entry (XPathScript Reborn) is the re-introduction of templates, and a generous slathering of overloaded shortcuts for stylesheet definitions.
This part will go over the 2nd “P”, partitioning. Learning about Oracle’s partitioning has gotten me more interested in how MySQL’s partitioning works, and I do hope that MySQL partitioning will develop to the level that Oracle partitioning does, because Oracle’s partitioning looks very nice (then again, that’s why it costs so much I guess).
At Kscope this year, I attended a half day in-depth session entitled Data Warehousing Performance Best Practices, given by Maria Colgan of Oracle. These are my notes from the session, which include comparisons of how Oracle works (which Maria gave) and how MySQL works (which I researched to figure out the difference, which is why this blog post took a month after the conference to write).
First this week we have John Anderson filling us up on the Perl high drama of OSCON of earlier this week. In a nutshell the organizers provided, as it’s the tradition, ribbons to the attendees, and the Perl Mongers in the crowd got one reading Desperate Perl Hacker. The epithet, coined in an XML article written in 1997, was meant in good fun, but was received with a distinct lack of glee by the Perl hackers.
Dynamo: Amazon’s Highly Available Key-value Store” is a high level description of a data store, written by Amazon to solve the problem of a system where updates must never ever fail and must take less than a specific amount of time in 99.99% of the cases. No matter what happens to the servers or the network, updates to the system must continue as usual, and they emphasize that they deal with hardware and network failures nearly constantly.
