  SOA/Integration/EA Info sites
Since one of my main responsibilities is to keep up with goings on in the SOA/EAI/EA space, I try to read a ton of blogs and web sites.

eBizQ has been pretty handy with their free webinars. They are usually dull (as their archive shows such gems as "Measuring the Value of BPM", "The ROI of SOA" and "Where Data Meets SOA: Data Services"), but are actually a pretty decent source of ammo for when the suits start asking the tech group about why we should spend money on SOA initiatives.

This isn't an astroturf post, just a useful site that I wanted to share with the SOA/EA crowd. Add it to your filter along with the other free IT magazines and sites (Infoworld, Baseline, CIOInsight, etc etc).

I'll eventually gather all these web sites, magazines and blogs into a google spreadsheet or my del.icio.us.

  Defining Architect roles
A few weeks ago, I read a serverside post that referenced marty andrews' post about defining software architecture roles. These posts happened just in time, as in the past two weeks I've been asked this question over and over.

My employer has been trying to define what exactly an architect is so they can create a career path for other engineers and architects. Currently we have:


This is what the titles are supposed to mean, but in my company (and perhaps yours) they really just mean how much you get paid. So they could just as well be "Architect 0" through "Architect 4".

But there does seem to be a large set of high paid consultants out there who practice "Enterprise Architecture". Sort of big picture guys who are able to go into non-tech huge companies and help with the 25k feet picture. This seems like the only real definition that really fits the term "architect" as far as technical systems are concerned.
 
  Calling BouncyCastle provider explicitly
I started to reply to ginni's comment to my last post but ran out of room so I will expand on a separate post.

Since specifying the provider wasn't working properly, I had to skip the JCE API and call out to BouncyCastle directly. Following the 1.34 javadoc, I wrote some code like this:

byte[] clearBytes = myString.getBytes("UTF8");
org.bouncycastle.crypto.digests.MD5Digest md5Digest = new MD5Digest();
md5Digest.update(clearBytes);

byte[] hashedBytes = new byte[16];
dm4Digest.doFinal(hashedBytes,0);


That's pretty much it. You can then use something like Jakarta Commons Codec's Base64 to encode into a printable String.


byte[] base64Bytes = org.apache.commons.codec.binary.Base64.encodeBase64(hashedBytes);
String displayableHashValue = new String(base64Bytes, "UTF8");


Of course this method has its drawbacks: specifically that if you ever want to use a provider other than BouncyCastle, it involves code changes. But this was the fasted way to get the system running without error. And the likelihood of us ever replacing BouncyCastle is small enough that I can live with code changes.
