What makes a good programmer.

I liked this particular description of what makes a good programmer because it describes things about me! Really, I thought the "Appetite for learning" means a great deal - new languages, techniques, points of view all mix into the stew of ideas you bring to bear on a problem.

Furthermore I loved this comment:

"Lazyness. The need to spend 10 hours so that a 1 hour job can be done in 10 minutes."

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...

Risk Mitigations for Custom Applications

In many healthcare applications, often due to the cloistered nature of the use cases – e.g. it will only be accessed by users authorized in a particular facility, such as an operating room suite – the needs for Authentication and Authorization are minimized when the system is designed and implemented. This presents a risk as soon as you allow for the possibility of users with ill-intent or that otherwise want to operate outside their given roles. Custom applications need to consider these possibilities and implement the following measure to ensure the integrity of the system. 1. Authentication and Authorization Controls: Multi-Factor Authentication (MFA): Implement MFA for all user logins. This adds an extra layer of security beyond just a username and password. Role-Based Access Control (RBAC): Grant users access only to the data and functionalities they need for their specific role. This minimizes the potential for unauthorized access. Strong Password Policies: ...

JavaScript and JQuery Palettes...

I have been immersing myself in the world of d3js and more, specifically Plotly.js . This has required me to look at palettes, and to create some palettes - which I did with Paletton . I find it tedious, so I am creating some helpers, like the code below which displays a given list of palettes (each of which is simply an array of colors in your favorite format). <table id="Palette"> <tbody></tbody> </table> <script> var defaultColorsPalette = ["#ffd99a", "#225ea8", "#ffc09a", "#9dc4f4", "#ffbf58", "#ffdb58", "#257294", "#ff9658", "#61a1f3", "#ffa719", "#ffce19", "#ff6e19","#ffe99a", "#2a82f2", "#ff9e00", "#ffc900", "#ff5f00", "#036bf0" ]; //via colorweb2 var sequentialMultihueBlueYellowPalette = ["#ffffd9", "#edf8b1", "#c7e9b4",...
