You ' re the best. Please make more.


I'll probably be using C and unoptimized assembly as performance references. It's possible to speed up interpreted languages like Java or Python from within Java or Python, but it's very difficult, as predicting what the interpreter/compiler will do is very complicated. With C, you can often trick the compiler into generating the code you want it to generate, though even there, it can be tough for anything more than a one-liner. We could look through disassembled code, but it usually just looks like a huge mess.

As for using an interface from an interpreted language to a compiled language, it's a good idea, though I'd probably want to save it for the full application examples at the end, since most of the examples throughout will be just a function or two. I don't know how the Python/C API is, but JNI is a *big* pain, especially if you use it the way they want it to be used. :D


Another great series that I am eager to watch.

Ehm, I am assuming that you'll use some compiled language rather than an interpreted language.

Although I think that watching some Python code optimized to the 'maximum' using assembly after going through byte code or the Python/C API might make it more interesting. Just a thought.

looking foward to watching more!


Very nice! I am looking forward to the rest of the series.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Neil
