One of the highlights of my day is pouring a cup of coffee and listening to this playlist:

while I check what my plans are for the day and how the calendar looks like.

El Castillo de Montalbán (Toledo) es una joya de la ingeniería templaria. Con torres pentagonales únicas y defendido por el cañón del río Torcón, es una fortaleza casi inexpugnable. 

Te cuento su historia en mi último artículo: https://mgallende.com/castillo-de-montalban-un-coloso-templario/

New article on NUMA:

Memory placement can make/break sub-microsecond latency targets. Remote NUMA = 2x slower access (120ns vs 60ns).

Beginner-friendly coverage of topology detection & allocator strategies for trading systems.

Can someone explain to me why in 2025 we still cannot create desktop zones in MacOS?

New: Why P99.9 > average in HFT

100ns avg looks good
10μs P99.9 = losing money

That 0.1% tail kills profits.

Fix: zero-alloc paths, wait-free structs, pre-alloc buffers

You're only as fast as your slowest percentile

If you want your HFT operations perform up to the limit of the metal, you need to bypass the kernel for network, this paper is a solid base in uderstanding this solution:

Hace 89 años, el fascismo asesinó en Granada a Federico García Lorca, pero sigue vivo en la memoria popular, y en las bibliotecas y teatros de todo el mundo.

Hay que seguir reivindicando verdad, justicia, y reparación, para todas las personas aún en cunetas y barrancos de toda España.

Working on a benchmark suite for my Rust HFT framework. Current tests cover TSC timing, precision timers, memory allocation, and system process overhead.
Next up: network I/O, trading pattern benchmarks, and concurrency testing.

Just published a new theory article on rustquant.dev this time about iceberg and stop-loss orders in the context of a Rust-based order book engine.
Not an expert, just documenting the journey.
