In this post:
- Fit a curve of degree N to a data set, getting data points 1 at a time.
- Storage Required: 3*N+2 values.
- Update Complexity: roughly 3*N+2 additions and multiplies.
- Finalize Complexity: Inverting a (N+1)x(N+1) matrix and multiplying by a vector to get polynomial coefficients.
- Simple C++ code and HTML5 demo at bottom!

The C++ standard doesn’t dictate exact implementation details for standard library classes, so it’s unsurprising that details of memory usage are missing from most references.

STL Container Memory Usage when Developing with C++
When writing C++ code for many platforms the STL container memory usage can vary between implementations (Microsoft, GNU, etc). Make the right tradeoffs.

C++17 - Why it's better than you might think : Level of Indirection
From Mark Isaacson's Meeting C++ talk, 'Exploring C++ and beyond' I was recently interviewed for CppCast and one the news items that came up was a trip report from a recent C++ standards meeting (Issaquah, Nov 2016).

We have RAII in C++ and therefore the totally deterministic destruction of objects. But, what is RAII? That's the topic of this post.

Another year and another C++ Status! It’s hard to believe, but it’s my fifth time I am writing this summary. And, as usually, C++ language is very alive. The biggest news for the year?
