I had wrote a kind of rant about Perl in Japanese. In this article, I mentioned about an interoperability issue between Ingy’s boolean and JSON::XS.
However Dan fixed the issue and Ingy released boolean 0.29 with this fix. How awesome… Probably I had to mention more difficult issue like Stevan mentioned subroutine signatures in his slide.
Anyway, thank you Perl Mongers!
I read Fumi’s Japanese summary about How Samsung Became the World’s No. 1 Smartphone Maker. It is definitely insane but interesting story.
One way of modeling social network data is as a social graph, where entities or nodes such as people, posts, comments and pages are connected by links which model different relationships between the nodes. Different types of links can represent friendship between two users, a user liking another object, ownership of a post, or any relationship you like. These nodes and links carry metadata such as their type, timestamps and version numbers, along with arbitrary payload data.
In LinkBench, every link has
`data` varchar(255) NOT NULL DEFAULT '',
and every node has
`data` mediumtext NOT NULL,
I think there is no RDBMS textbook which recommends such a column but I know it’s useful in the OLTP world.
