Happy Singapore 61th 🇸🇬

Humans are bad at writing bug-free code. Relying on larger, more concentrated closed-source honey pots is not risk mitigation. It only increases the impact of an incident.

The best firewall is an air gap. The best randomness is a pair of dice.

C++ nugget: printf View article →

C++ is often treated like an old grandpa language: powerful, cranky, and assumed to have stopped evolving sometime around the arrival of Java, C#, and Python. Except it didn’t. C++ changed dramatically with C++11. Since then, new versions have followed roughly every three years, bringing a steady stream of features that make the language safer, more expressive, and, occasionally, less hostile to human beings.

Richard got really good at spelling out nuanced concepts clearly. "Bitcoin n'est pas un investissement par nature. Il se comporte comme un investissement par phase historique. Sa performance n'est pas son objectif, c'est le symptôme de son adoption progressive comme standard monétaire. Autrement dit, ce n'est pas un investissement qui pourrait devenir une monnaie. C'est une monnaie en devenir qui temporairement se comporte comme un investissement.”

C++ nugget: HFT firms do not use virtual machines, they prefer the predictability of actual hardware. Here is a problem seen on actual hardware and not so much on VMs: a machine may have more than one CPU socket. Each CPU socket has its own DRAM. How to tell whether the hot-path thread is talking to the local memory unit and not to the remote one? Answer: Linux allows you to pin a thread to a specific core and restrict heap allocation to the local node. View article →

Ever since I started retraining at modern C++, my gf suspects I have an std::

C++ nugget: The C++ compiler assumes that if two pointers have different types, they must have different addresses. This is not always true: in HFT you often pre-allocate memory then create/destroy objects with placement new. To avoid subtle bugs: std::launder View article →
