1D Simulation of Ocean Waves

The upcoming 1.11 release of Floating Sandbox sports a completely redesigned wave sub-system. The previous wave simulation was a simple superimposition of two sine waves, for which the user could control height and speed. The visual results were not that bad with default settings: When increasing wave height, though, the “fake” nature of the waves […]

Euler Fights with Square Drag

While working on Floating Sandbox 1.10.0 I stumbled upon an issue that I totally didn’t see coming. A user (Dkuz The Fox, thank you) reported that when placing an anti-matter bomb on the tail of the Submarine 3000, the submarine would at times disappear. And even more intriguing was the fact that this would only […]

A Physics Puzzle

While working on Floating Sandbox 1.8 I realized I’d gone through 8 versions without noticing a subtle bug in the buoyancy simulation. Fixing the bug challenged my common sense on how things really sink underwater, and after bringing up the discussion at lunch with some of my colleagues, I realized it was not only my […]

Momentum-Based Simulation of Water Flooding 2D Spaces

For the 1.5.0 release of Floating Sandbox I had decided to work on rethinking the simulation of water entering physical bodies through a hole in the hull. The 1.4.0 simulation was based on simple Newtonian-like mechanics and consisted of 3 steps: Water Intake: each point adjacent to a hole in the hull would take a quantity […]

Proud of My Patch Panel

Today was my last day of work at my current company, and I paid a visit to the company’s offices to return company property and cleanup my drawer. On my way out, I had a last glance at the patch panel of the office – it took me a few days in February 2010 to […]

Chris Eng: How to Become an Information Security Thought Leader

Radi brought to my attention this post from Veracode’s Chris Eng on How to Become an Information Security Thought Leader. This video reminds me of so many thought leaders I’ve met. If only I could get them to watch it now 🙂

A Dimensional Model for Vulnerability Management

For the past few months I’ve been working on an interesting problem for a large Dutch financial institution. The driver is a situation quite common in the risk management world: the security office of the institution is trying to centralize the reporting of all risk-related information, and among other things, vulnerability management data plays a […]
