Deep Engineering #59: Lieven De Cock on C++ Coroutines as a Build-It-Yourself Kit
The promise type, the coroutine handle, and why the boilerplate belongs in a library rather than your codebase
 • Saqib Jan and Lieven de Cock
Building a C++ Coroutine by Hand, and Why You Probably Should Not
Three coroutines built from scratch, the boilerplate each one needs, and the library support that makes most of it unnecessary
 • Lieven de Cock
Deep Engineering #58: Sebastian Hassinger on Where Quantum Progress is Real
Encoding ratios, code distance, and the unsolved physics underneath vendor roadmaps. Plus where quantum pays off first and how a classical developer…

Materials Science Gets Real Value From Quantum Before Anything Else
Small molecule chemistry follows close behind. Optimization, cryptography, and machine learning all need thousands of logical qubits, so those sit much…
 • Saqib Jan and Sebastian Hassinger
Eighty Years of Boolean Thinking Is the Real Barrier to Quantum Adoption
The hardware is not the hard part for enterprises. Recasting business problems in quantum terms means unlearning assumptions about problem solving that…
 • Saqib Jan and Sebastian Hassinger
Quantum Computing Beyond the Hype with Sebastian Hassinger
How to tell genuine quantum progress from hype, why qubit count misleads, where the technology delivers value first, and how a classical developer…
 • Saqib Jan and Sebastian Hassinger
Python Developers Can Learn Quantum Computing by Fixing Bugs
Most quantum programming happens in Python, and the fastest way in for a working developer is contributing to the packages themselves rather than…

Deep Engineering #57: Rory Preddy on Cutting Agent Costs Without Ranking Engineers
Agent profiles as shared infrastructure, spend caps inside the authorization boundary, and the metric that replaces tokens burned
 • Saqib Jan
I burned 51 million tokens on one merge conflict, and the model was not the problem
Cache the prefix, compact the context, route to the smallest model that fits, and put a ceiling on every loop
Site Reliability Engineer (SRE) Interviews Measure a Depreciating Skill
Notable engineering leaders on motivation, ambiguity, tribal knowledge and the measurement problem behind every reliability hire that did not work out
 • Saqib Jan
Deep Engineering #56: Peter Zaitsev on Choosing a Database Like You Can Never Leave It
Database choice is the decision teams rush most and regret longest, because a database is far easier to adopt than it is to leave.
 • Saqib Jan and Peter Zaitsev
Codex as a Teammate, Not Autocomplete
The developers who get the most from an AI coding agent don't prompt better. They scope better, test better, and review better.
