Pedestrian bridge collapse in Florida

Does anyone know more about the causes of that collapse?

Now that we supposedly know so much about mechanics, why does a small-span bridge like that collapse?  

It it because we are optimizing prematurely based on false confidence in numerical models?

Can we predict when the Larsen-C ice shelf will fail?

My opinion is "Not yet".

What stops us from predicting the date on which the Larsen-C ice shelf will fail?

Reading XML files containing gzipped data in C++

Once upon a time, the CEO of my company asked me why I did so much software engineering for my work.  My response was that software engineers were unlikely to produce what I needed in the short time frames that I had at my disposal without me spending a huge amount of time training them.

Creating a multi-keyframe animation with d3.js.

Something that should be in the toolbox of every modern researcher.  Static plots in journals are not good enough given today's technology.

Forward vs backward Euler for return algorithms

In Part 5 of my series on return mapping for plane stress plasticity, I claim that the obsession with backward Euler is not justified if accuracy is important.  See

Let me know if you disagree and why.
