Quote of the Week

"You can either have software quality or you can have pointer arithmetic, but you cannot have both at the same time." – Bertrand Meyer

Reading List

The Illustrated AlphaFold
A visual walkthrough of the AlphaFold3 architecture, with more details and diagrams than you were probably looking for.

The missing parts in Cargo
The article discusses the limitations and missing features of Cargo, Rust's package manager, particularly in complex, polyglot projects. It highlights issues with cache management, build scripts, conditional compilation, and cross-compilation, and proposes a more modular and experimental approach to address these challenges.

What is Old is New Again
The past 18 months have seen major change reshape the tech industry. What does this mean for businesses, dev teams, and what will pragmatic software engineering approaches look like, in the future?

Engineering Principles for Building Financial Systems
Best practices and principles to create accurate and reliable software based financial systems.

Surprises with Rust's `as` (and Python division)
The article discusses the challenges and potential risks of using Rust's as keyword for type casting, particularly for programmers coming from higher-level languages. It recommends using TryFrom instead of as for safer type conversions, as it allows for explicit error handling and prevents unexpected behavior when dealing with numeric types.

Introducing Substrate
Substrate is a crowdsourced project designed to enhance understanding, communication, and action in order to move humanity forward.

Gotchas with SQLite in Production
The article discusses the challenges of using SQLite in production environments, highlighting issues like configuration for multi-threaded access, network limitations, concurrency constraints, and the need for careful transaction management. While SQLite offers simplicity for single-machine applications, its limitations make it less suitable for scenarios requiring high concurrency, distributed databases, or complex migrations.

Extrinsic Hallucinations in LLMs
The article defines extrinsic hallucinations in Large Language Models (LLMs) as fabricated outputs not grounded in either the provided context or the LLM's training data. It explores two types of hallucinations: in-context (consistent with source content) and extrinsic (not grounded by pre-training data).

Watch and Listen

Zig as a Multi-OS Build System
The ZigLang team have put an astonishing amount of effort into making Zig work an effective tool for compiling C across different architectures. Work that benefits the Zig language, but also has a chance to benefit languages like Python and Rust. Or indeed, any language that uses native C libraries somewhere in its stack. So this week we’re joined by Loris Cro of the Zig team to dive into how you make a reliable, cross-platform toolchain that can compile C anywhere it finds it.

Migrating Coinbase's 56 Million Users to React Native: Key Lessons and Takeaways
Nick Cherry, a former Coinbase employee and React Native expert, discusses the performance challenges encountered with React Native at Coinbase and the solutions implemented to optimize it. He also shares his experience working on the mobile app for Farcaster/Warpcast, a decentralized web3 social network, detailing the development process, tools used, and challenges faced.

"Agile Signaling" is Gaslighting The Tech Industry
Many tech companies claim to follow agile methodologies but fail to truly adapt to change, leading to widespread discontent among software developers. True agility, which means easy adaptation to change, is rare, and frameworks like SAFe have further distorted the agile concept. As AI accelerates disruption, genuine agile development is more crucial than ever
