What if we added a new field in the META.json — let’s call it x_help_wanted — that would contains all the different types of help a module maintainer could require? Positions like maintainer, co-maintainer, coder, translator, documentation and tester. We could even have a Dist::Zilla plugin to populate that field for us.
This is going to be a short one, but I think the changes to GitStore are cool enough to deserve a little blog-squeal, let’s have a look.
I played with Mongo and looked at Mongoose, which are nifty but… holy schmolee are mongo databases huge. And then I re-discovered DBIx::NoSQL, which was pretty much smack what I wanted. But I needed a way to easily serialize my objects for it. So I dragged in MooseX::Storage to the mix. And then I had fun with helper classes and roles to make the interfacing between the two systems as smooth and slick as a buttered piglet.
We’ve got a few clients already using Enterprise Manager 12c Cloud Control. The interface and navigation have improved a lot from the 11g version in my opinion but, as with any new release of anything, there are still quite a few bugs to be fixed. Last week, after working with Oracle on some of these bugs, they asked us to apply the Bundle Patch 1 (BP1) to one of our clients’ installation. The first thing that I noticed when I started looking for information about BP1 was the amount of warnings from different people I found in MOS and around the internet.
So how is the actual “waiting on lock” implemented? How does session B waiting for a transaction to commit started by session A, knows that the resource is free for use? To find out how it is implemented, I have traced Oracle foreground processes. I tried this on Oracle RDBMS 11.2.0.3 running on Linux. This is a excerpt of system calls being executed during a session waiting for a lock:
This is just a very short blog entry to inform folks that there is an open discussion group over at LinkedIn for SLOB topics of interest. The group can be accessed through the following link
In the last few weeks, I launched quite a few small releases to CPAN. Taken separately, they are hardly worth a full blog entry, but taken together, they’ll make for a lovely N&I entry. So if you have been wondering what I’ve been up recently, here goes:
The purpose of this blog post is to share my favorite speakers list from Collaborate 12 and give you hints on who you may want to listen at future conferences. Let me start with 4 speakers that I didn’t hear before Collaborate 12.
Until very recently, SQL Azure was the only solution offering SQL server on cloud, Google Cloud SQL offering MySQL only and Amazon offering MySQL and Oracle Not anymore! The online retail and cloud solution giant is now offering SQL server as part of its RDS service and also added ASP.NET support for AWS Elastic Beanstalk
The purpose of this blog isn’t to show off the results of my presentation at Collaborate conference, but to inspire you (and maybe myself in the future) and give you additional motivation to never give up on reaching your dreams if you truly believe in them.
