About Genbox

My name is Ian (Denmark) and I do science, security, algorithms, software architecture and high-performance stuff.

I built Farseer Physics Engine 3.0, SimpleS3 and about 25 other open source projects. Check them out over at https://github.com/genbox

I am also the founder and director of Chronos, a platform for investigating large-scale security incidents using forensics techniques.

    Publishing a zero knowledge proof rather than the solution is pretty clever.

    If I would like to build a visualization like this, but for a data ingestion pipeline, any tips on where to start? I have it visually in my head, but it feels overwhelming getting …

    PHP loads all available functions into a giant hashset (see zend_disable_function in PHP's source). 'disable_functions' removes the functions from the hashset, making them unavaila…

    Are you saying that two weak factors are more secure than one strong factor?

    I agree with this. As someone who took 3 degrees in computer science, one called "systems developer" and another called "software engineer", I can confidently say we have a taxonom…

    Thanks! The direct hooking into the narrow phase solver is the most performant way to go about it, but it does present several issues in state management. I did the same thing in F…

    Wow. That is actually very impressive. Things have moved quite a lot since I did a physics engine. What makes it difficult to integrate?

    That's a bit disingenuous. Can you substantiate your claims?

    The security of the Apple ecosystem is miles ahead of others. Every time I reverse engineer some component of their OS, it is very different from what I've seen before. I always fi…

    The condition is called Anosmia and can stem from different sensor and brain conditions. It would be interesting to try the technique on people with these conditions to map the dif…

    It is also kinda a self-burn. Chromium an aging code base [1]. It is written in a memory unsafe language (C++), calls hundreds of outdated & vulnerable libraries [2] and has hundre…

    I generally agree. However, there are several important optimizations that Roslyn does not yet have. I love the improvements in newer versions of the compiler as much as the next g…

    Taking a bunch of data from the Korean National Health Insurance database and looking for one specific connection is less than helpful. Like carl sagan said: extraordinary claims r…

    It looks like a process model; isolation between programs with a system for inter-process communication, and running within a single process's memory. If I understand correctly, in…

    I ported BinaryFuse filter to C#, along with tests and benchmarks. BinaryFuse filter is an incredibly clever data structure. https://github.com/Genbox/FastFilter/tree/master

    I opened this post in a tab 3 days ago, but now it says "5 hours ago". Someone is playing around.

    A few years ago i picked up the old (but famous) cases of Brad Cooper and Casey Anthony as they have tons of available digital forensics evidence. I double-checked the forensics wo…

    C# started as a language tightly aligned with C++/Java, but has since moved to be something else entirely that is highly capable. I assume that free-floating functions are global f…

    Do you have any regrets about an algorithm/data structure and wish you picked something else?

    For those reviewing the changeset: There are two places where they read a value directly from $POST into an $args array. There is no validation applied, which means an attacker can…
