## Literate programming – effect on performance

After my introductory post on Literate Programming, it occurred to me that while the concept of being able to create documentation that includes variables from the code being run is amazing, this will obviously have some impact on performance.  At best, this would be the resource required to compile the $\LaTeX$ document as if it was static, while the “at worst” scenario is conceptually unbounded.  Somewhere along the way, pweave is adding extra code to pass the variables back and forth between the python and the $\LaTeX$, how and when it does this could have implications that you wouldn’t see in a simple example but could be catastrophic when running the kind of neural nets that my department are putting together. So, being a scientist, I decided to run a few experiments….1 Continue reading Literate programming – effect on performance

## Using Literate Programming in Research

Over my career in IT there have been a lot of changes in documentation practises, from the heavy detailed design up front to lean1 and now the adoption of literate programming, particularly in research (and somewhat contained to it because of the reliance on $\LaTeX$ as a markup language2).  While there are plenty of getting started guides out there, this post is primarily about why I’m adopting it for my new Science and Innovations department and the benefits that literate programming can give.

## Python: serious language or just for beginners?

Two months ago I hadn’t looked at a line of Python code – it was never a requirement when I was a developer and as I moved into management I worked with teams and projects using everything from C and COBOL through LAMP to .Net, while Python sat on the periphery.  I’d always considered it to be a modern BASIC – something you did to learn how to code or for a quick prototype but not something to be taken seriously in a professional environment.

I’ve always believed that really good programmers understand the boundaries and strengths of multiple languages, able to choose the right tool for the job, and finding the correct compromise for consistency and maintainability.  People like this are really hard to find1 although I do tend to veer away from individuals who can only evangalise a single language and say all the others are rubbish2.  Due to the projects I’ve been involved with, Python ability has been irrelevant and never considered part of that toolbox.
