Data type and byte order conversions for NSData using the STL
We’ve been spoiled working in Python’s numpy array library. Converting data types or byte order for numeric data in a numpy array is trivial (thanks to the work of numpy’s authors of course). When we’re in Objective-C land, the inability to change data types or byte orders on NSData instances is frustrating. So we’ve written [...]
What is a UI?
This year, I’d like to say a big thank you to the writers of numpy and scipy, the numerical and scientific libraries for Python. We use these open source projects very heavily in our work. The combined efforts of all of the contributors to these projects has made Python a premier language for numerical computation. [...]
Database vs. scientist
One of the founding principles of Physion Consultants is to bring cutting edge technology to scientists. When the computational tools cease to be a bottleneck in the scientific process, we feel that we’ve done our job. For many scientific applications, a relational database system (RDBMS) is the appropriate data repository. After all, great database engineers [...]
