Being in the office (thanks Aldert/Milton) with nothing but a big screen and no crying cat climbing up my legs certainly helps
I just committed a bunch of good improvements to the WSF framework. I ‘generified’ some of the WSF classes and also introduced a WebServiceActionContext.
The WebServiceActionHandler now looks like this:

public interface WebServiceActionHandler<Account extends […]

Quick followup to my previous posting about the Web Services Foundation framework that I’ve been working on.
Things are in pretty good shape now. The code is pretty much functional enough for us to start implementing some of our planned public web services. More about that later.
I’ve created an extra project that contains some examples on […]

It’s been quiet here but that doesn’t mean I’ve been sitting still. I’ve been quite busy actually.
Currently I’m working on a simple framework that needs to become Polar Rose’s standard way to do (public) web services. It is modelled after Amazon’s Query-style web services that they use for things like SQS and EC2 where the […]

We finally decided to open up a whole bunch of more pages that were previously behind a beta login. Sooo, here are some links as starting points:

Der Hoffmeister
The Dude - Love that movie. Amazing we detected the face with the crazy sunglasses.
My favorites
Some of my dear colleague’s favorites
A whole bunch of false positives - Also […]

Sometimes when you are in crazy situations you need to use crazy solutions.
Polar Rose is are a 95% Java shop. Basically everything is Java, from distributed image processing infrastructure to web sites and web services. (That five percent is some amazing C++ code to do the most difficult task of finding and analyzing faces.)
So, lately […]

Check out the polarrose-postgresql-uuid project hosted at Google Code. It contains a simple native UUID implementation for PostgreSQL. I did this as an exercise but I’m considering to put this into production since it saves a lot of memory and disk space. A whopping 47% on tables that have an indexed uuid column.
My next PostgreSQL […]

I’m going to make it a habit to do some nice hack in the two hours that I’m in the air when I fly home from the Warsaw office. LOT’s Embraer’s have a lot of (leg) room. specially compared to the crammed 737-400s that I usually fly with.
So to kick off this tradition I wrote […]

The Harvard Law Review published an interesting article titled “In the face of danger: facial recognition and the limits of privacy law“.
Although I don’t agree with everything in the article (it is mostly based on speculation since Polar Rose is not live yet), it is an interesting subject and a relevant and needed discussion now […]

At Polar Rose we’ve been using XML-RPC for our (internal) web services. Simply because it is such a simple protocol and fairly well supported in all (scripting) languages. I’ve really been avoiding the WS-* Deathstar for a while now but I finally bit the bullet and started using SOAP again.
Last night when I was flying […]

I’ve accepted a new job at Polar Rose, an exciting new company in Malmö. I’ll be working with a great team on some really interesting products and services built on top of our face recognition software. I’ll write more about what we are doing later.
BTW. We’re looking for people with a strong Java background.
