db4o: Object-Identity and High-Level-Caching
Posted by gamlerhart in db4o on September 28, 2009
In the last two posts (#1, #2) we never ever used anything like an id for any object. So how the hell does db4o identify objects? How does it ensure that existing object are updated? (All posts of this series: the basics, activation, object-identity, transactions, persistent classes, single container concurrency, Queries in Java, C# 2.0, [...]

Normally C- vs. Java-performance comparisons are wonderful and entertaining flame-wars. However this blog-post is very reasonable and each argument justified. I’ve stumbled by accident on a hand-cam-quality teaser of Doctor Who, End of Time from Comic-Con. Of course it contains a spoiler, but not a surprising one.

Activation is a very basic concept in db4o. In this post I’ll illustrate what it is, why it’s there and how you handle it.

Sadly, lots of developer [...]

7Stacks is a little tool which lets you create the well known ‘Stacks’ from Max OS X in Windows 7 (and Vista, XP). Of course it’s not as elegant as the original, but at least it’s now possible. I’ve played around a little with the tool and it works so far. However there are some [...]

Jetbrains has released the first beta of their new bug-tracker, YouTrack (previously code-named Charisma). I’ve used the EAP before and I liked it. YouTrack doesn’t focus on having thousands of features but on usability. It’s keyboard-oriented. For example it has an powerful search language instead of a complex search-form. It can also use Jira as [...]
