Linux Infrastructure Deep Dives

Curriculum • 14 Modules

Part 1 Dec 2024

Linux Defaults That Cost You Latency

Deep dive into vm.swappiness, THP compaction, and C-states. Kernel internals, measurements, and the design philosophy behind low-latency Linux tuning.

Part 1 Dec 2024

The Sub-50µs Cloud Lie How to Actually Get Deterministic Latency on AWS

Why cloud providers' latency claims don't match production, and the exact kernel bypass techniques that get you to deterministic sub-50µs RTT on c6i.metal instances.

Part 2 Dec 2024

PTP or Die Hardware Timestamping for Regulatory-Grade Time Sync

Why NTP is insufficient for HFT compliance, and how to implement IEEE 1588 PTPv2 with hardware timestamping to achieve sub-100ns accuracy.

Part 3 Dec 2024

CPU Isolation for HFT The isolcpus Lie and What Actually Works

Why the standard 'isolcpus' kernel parameter doesn't fully isolate your critical threads, and the combination of settings required for true deterministic scheduling.

Part 4 Dec 2024

Memory Tuning for Low-Latency The THP Trap and HugePage Mastery

How Transparent Huge Pages cause unpredictable latency spikes, and the explicit HugePage reservation strategy that eliminates memory stalls.

Part 5 Dec 2024

Network Optimization Kernel Bypass and the Art of Busy Polling

How the Linux network stack adds latency, and the interrupt coalescing, busy polling, and AF_XDP techniques that reduce it.

Part 5 Oct 2024

I/O Schedulers Why the Kernel Reorders Your Writes

Deep dive into I/O schedulers, Direct I/O, io_uring, and AWS EBS optimization. Block layer internals for predictable storage latency.

Part 6 Nov 2024

Trading Infrastructure First Principles That Scale

Architecture decisions that determine your latency ceiling. AWS, Kubernetes, monitoring, and security patterns for crypto trading systems.

Part 7 Jan 2025

Kubernetes StatefulSets Why Trading Systems Need State

Deep dive into StatefulSets vs Deployments, pod identity, PersistentVolumes, and graceful shutdown patterns for trading infrastructure.

Part 8 Jan 2025

Trading Metrics What SRE Dashboards Miss

Fill latency, position drift, market data staleness. The SLOs that prevent losses, not just track uptime. Prometheus, Grafana, and alerting patterns.

Part 9 Dec 2024

eBPF Profiling Nanoseconds Without Adding Any

Deep dive into eBPF, bpftrace, and kernel tracing. How to measure latency at nanosecond precision without the observer effect.

Part 10 Jan 2025

Market Data Infrastructure WebSocket Patterns That Scale

Deep dive into WebSocket reliability, sequence gap detection, Kubernetes patterns, and monitoring for multi-exchange market data systems.

Part 11 Jan 2025

The Nanosecond Economy HFT Infrastructure Fundamentals

FPGA feed handlers, kernel bypass, and the physics of sub-3µs trading. Why infrastructure is the edge in high-frequency markets.

Part 11 Dec 2024

Measuring Latency in the Browser A Meta Demo

The RTT badge on this site measures real latency. Here's how, using the Performance API, Cloudflare edge, and the same principles that apply to trading.

On-Chain Infrastructure: DeFi

Curriculum • 4 Modules

Part 1 Dec 2024

Zero-Trust Wallet Architecture for Institutional DeFi

How to replace air-gapped cold storage with a policy-driven MPC signing pipeline, achieving fast deployment cycles without compromising cryptographic guarantees.

Part 2 Dec 2024

Building a Crypto Exchange on AWS The Architecture of Liquidity

Reference architecture for a high-performance crypto exchange on AWS, covering the Matching Engine (LMAX pattern), Market Data Ingest, and MPC Custody integration.

Part 3 Dec 2024

Defense in Depth Security Architecture for High-Stakes Trading

Zero Trust networking with Teleport, supply chain security with Sigstore, and real-time risk engines with Chainalysis. How to secure an exchange from the inside out.

Part 4 Jan 2025

Defense in Depth Engineering DeFi Protocols That Don't Get Hacked

Security architecture for DeFi protocols: enclave signing, rate limiters, circuit breakers, and the incident response playbook.

Curriculum • 4 Modules

Part 1 Dec 2024

The 100ms Tax Why Most Block Builders Lose Before They Start

A first-principles breakdown of why infrastructure latency, simulation failure rates, and observability gaps eat block builder margin — and how to fix it.

Part 2 Dec 2024

Antifragile MEV How We Profit When the Network Breaks

Applying Nassim Taleb's antifragility to blockchain execution infrastructure. Why reorgs are profit opportunities, multi-builder hedging is arbitrage, and chaos engineering is a competitive advantage.

Part 3 Dec 2024

The Insider Threat Securing Order Flow When Your Own Infrastructure is the Enemy

Why the biggest threat to MEV infrastructure is not external hackers-it's rogue employees, compromised builders, and your own logs. Enclave signing, OPA firewalls, and compliance logging without alpha leakage.
