Note to self: Don't write your own encryption.

There are already capable, tested and even tried an true encryption algorithms. Implemented across platforms and languages and built into libraries and services. And did I mention "Tested"? With mathematical validations of how hard they should be to crack?

If you actually need to encrypt things, then use existing algorithms and software to actually encrypt things. You'll have enough to worry about with key management, library verifications and making sure the rest of the team gets up to speed that, no, it's not just Easier | Faster | Better to do it yourself.

Unless of course your sole job is creating, writing, testing, proving and implementing encryption algorithms, because you have all the maths...

Unit Testing - What to Test

This I wrote to answer a question that came up when we were discussing our software process and I was training developers on how to unit test. It seems a simple enough question, but I kept pondering it and delving deeper until I realized I needed to write this monograph. What unit tests should we write? How do we know what to test? Ideally, unit tests should cover every path through the code. It should be your chance to see every path through your code works as expected and as needed. If you are practicing Test Driven Development then it's implied everything gets a test. In the real world, you might not be allowed to test everything - for instance, if the testing suite ends up taking a week to run, then the world will have changed by the time it finishes and the test results will be obsolete. Unit testing at it's basic is testing an object, a method - the smallest unit of your code that it can test independently. It should test the inputs "goes into" an...

Healthcare and Health Informatics Glossary

Here is a glossary of terms useful in Healthcare and Health Informatics ACO (Accountable Care Organization) MEDICARE’s outcomes-based contracting approach Arden Syntax an approach to specifying medical knowledge and clinical decision support rules in a form that is independent of any EHR and thus sharable across hospitals ARRA (American Recovery and Reconstruction Act) the Obama administration’s 2009 economic stimulus bill Blue Button an ASCII text based standard for heath information sharing first introduced by the Veteran’s Administration to facilitate access to records stored in VistA by their patients. The newer Blue Button + format provides both human and machine readable formats.

It's all broken...

So, Scott Hanselman struck a chord again: Everything's broken and nobody's upset . The worst part is I can see that I'm part of the problem on both sides . I've excused many problems with software - shrugging as I restart the software or reboot. I save my anger for those occasions where I fell I've lost serious work and substantial time. Other than that I accept problems, glitches, crashes as "the cost of doing business". I believe it's actually because I've amused myself and earned a living creating software, that I am able to accept what's often pitiable quality. I've spent time working on systems that are not much more than breadboards with wires cascading from it, where getting something, anything to work was a huge accomplishment. But that was then and this is now. No way would I put up with a car that suffers from numerous small problems as today's software can. And putting these two thoughts together, it's now frightening ...
