One of the items on the to-do list for Dancer 2 is to verify that most of the plugins already written for Dancer 1 will still work for Dancer 2. Well, I thought, that’s just like doing smoke testing for a small subset of Perl modules. How hard can it be? Lets get cracking…
I was thumbing through the photos in my iPhone from my Melbourne trip of August, where I went to present two sessions on Exadata in Insync12 from Pythian. I spent couple of hours on first and last day in sight-seeing or should I say my iPhone did the sight-seeing, and I nursed him. As I was going through the photos, I realized I was kind of watching those places first time. There were many things which were present in the photos, but I never saw them with my own eyes while walking or traveling in the trams or cabs.
Today, I had some bit of fun and created a micro-web service as a one-liner. But then I thought that using almost 70 characters for a web service was awfully long-winded. Surely there was a way to make our Dancer more efficient. But how? How about… by getting a MC involved?
I’ll not try to bamboozle you: diving into Moose’s metaclass system is not easy because playing with classes that beget classes is heady, confusing stuff. It often feels like trying to type by looking at the keyboard in a mirror. But once that dragon is tamed, it can do truly wonderful, terrible things…
A while ago, I spotted TimelineJS, a JavaScript library to create gorgeous timelines, and earmarked it to a future app. Last week, I finally get to play with it by creating Yarnline, an itsy-bitsy mashup app that takes the projects of a Ravelry user and display them in a chronological manner, like so
This past week I attended OSCon, the annual conference for open source’s true believers. And there was a religous fervor in the air, particularly from the point of view of someone more accustomed to Oracle conferences. The companies generating buzz were the small companies built around development of their own open source products. There are a surprising number of them out there, especially relating to multiple forks of a popular product like MySQL or Hadoop.
One of the great joys of Perl and CPAN is how it allows you to stand on the shoulders of giants. By picking the right tools, applications that are not that trivial can be built in a matter of days, if not hours, and the goal of my little project of today is to demonstrate that very thing. So. Grab a helmet and put your mouth-piece on, for this time I aim at nothing else than to blow your mind to awestruck smithereens.
Friday 13 of June 2012 I was oncall Oracle DBA. I got to work on a high priority client’s request. A financial team of one of my team’s clients was executing final steps of a year closing process in their ERP production environment and had a problem.The step that I received a complain about took 2 hours and still didn’t complete. I was told that last year the same step completed in 20 minutes. Looking back I think it may be beneficial for someone of you to read how the issue has been troubleshooted and resolved. It may give you a chance to learn something or share some better diagnosing techniques with me and others. Please do not hesitate to use comments section of this blog post.
As a third person just asked me how to prepare for OCM exam in the last 2 days, I decided to make my answer publically available. I will leave you to discover the formal path yourself and give you a guideline in terms of how and how long to prepare to the exam.
A couple of years back, I created WWW::Ohloh::API because it seemed to be a fun thing to do. And, trust me, it was. But now, since I’m not using that module personaly, I thought it would be a good idea to see if anyone would be willing to co-maintain it. Before I could do that, though, there was two little matters I had to deal with.
