Run LLMs Locally on Your Mac with Ollama

Apple announced Apple Intelligence at WWDC 2024, promising "AI for the rest of us," but its arrival feels distant. Meanwhile, Ollama lets you run large language models (LLMs) like llama3.2 locally on your Mac. Think of it as 'Docker for LLMs' – easy to pull, run, and manage models. Powered by llama.cpp, Ollama uses Modelfiles for configuration and the OCI standard for distribution. Running models locally offers advantages in privacy, cost, latency, and reliability. Ollama exposes an HTTP API for easy integration into apps, as demonstrated by Nominate.app, which uses it for intelligent PDF renaming. The article encourages developers to build the next generation of AI-powered apps now with Ollama, instead of waiting for Apple's promises.

Ken Thompson's Sneaky C Compiler Backdoor: A Reflection on Trust

2025-02-16

In his paper "Reflections on Trusting Trust," Ken Thompson, co-creator of UNIX, recounts a chilling tale of a self-replicating backdoor he inserted into the C compiler. This backdoor would automatically inject itself into the login program during compilation, granting him unauthorized access. The insidious part? Even removing the backdoor from the source code wouldn't stop the compiler from re-inserting it during compilation. This story serves as a stark reminder of the limitations of trusting software and the inherent difficulty in ensuring complete security, even with source code review.

Beyond Two-Week Sprints: Exploring ShapeUp, Plan>Build>Ship, and GSD

Tired of the traditional two-week Scrum sprint? This article explores three alternatives: ShapeUp, Plan>Build>Ship, and GSD. ShapeUp emphasizes a six-week development cycle, starting with a thorough 'Shaping' phase, followed by a 'Betting table' decision-making process, and finally the 'Building' phase, avoiding the rush of short sprint cycles. Plan>Build>Ship is a simplified waterfall model where each feature is handled by a dedicated team from planning to delivery. GSD (Get Shit Done), popularized by Shopify, emphasizes efficient execution, using the internal tool Vault to track project progress, focusing on projects rather than tasks, and promoting team collaboration. These three methods each have unique characteristics, offering product teams more choices and helping them find the development process best suited to their circumstances.

The Coming AI Revolution in Software Engineering

2025-02-15

Large language models (LLMs) are rapidly improving their ability to write code, leading to the exploration of pure-AI software engineers. In the short term, software engineers should learn AI, improve their status, and leverage AI tools. Mid-term, expertise in maintaining and improving large legacy codebases will become increasingly valuable, as LLMs still struggle with complex, hard-to-verify projects involving massive amounts of code. Long-term, the core competency of software engineers will shift towards accountability and trustworthiness—qualities LLMs find difficult to replicate. Ultimately, those engineers who can oversee AI systems and ensure the reliability of their outputs will be the last to go.

Firefox and the Silent Audio Killer: How Websites Waste Your CPU and Battery

2025-02-15

The author discovered annoying white noise in Firefox, stemming from websites inefficiently using the WebAudio API's AudioContext. Many sites create and leave AudioContexts active even without playing audio, leading to excessive CPU and battery drain. While Chrome automatically suspends unused AudioContexts, Firefox doesn't, prompting the author to create a browser extension to mitigate the issue. This extension automatically suspends AudioContexts and attempts to resume them when sound is needed, saving resources.

Unit Testing Reimagined: Beyond the Dogma

2025-02-15

Traditional unit testing often falls into dogma, leading to wasted time and ineffective tests. This article challenges the very definition of a 'unit', advocating for user-centric integration and end-to-end tests instead of rigidly testing every class or method. The author suggests reducing reliance on code isolation and mocks, leveraging real databases and tools like Docker for increased efficiency and meaningful tests. TDD is presented as not a silver bullet, with software architecture design prioritizing non-functional requirements. Ultimately, the key decision in choosing a testing strategy is balancing quality assurance, refactoring resilience, and speed of feedback; often, modern tools make fast e2e or integration tests feasible.

Incentives, Not Education: The Key to Solving Code Quality Issues

Google once tried using a color-coded food program to encourage healthy eating among its employees, overlooking the impact of stress and time constraints. Similarly, addressing code quality issues shouldn't solely focus on educating engineers about coding standards. Instead, it's crucial to consider incentive mechanisms. Engineers writing poor code aren't necessarily lacking knowledge; they might be under pressure to meet deadlines or overwhelmed by demanding tasks. Therefore, the key to improving code quality lies in improving the work environment, providing adequate time, and establishing reasonable incentive systems, rather than simply emphasizing knowledge education.

Rust's Ownership System: Preventing Memory Errors at Compile Time

Rust's Ownership System: Preventing Memory Errors at Compile Time

Rust prevents memory management errors at compile time through its ownership system and RAII (Resource Acquisition Is Initialization). Each value has only one owner; ownership can be moved between variables, but a given object cannot be mutably referenced in more than one place at a time. Example code demonstrates ownership transfer: after the ownership of variable `a` is moved to `_b`, accessing `a` again results in a compile-time error, ensuring memory safety. This contrasts with traditional garbage collection; Rust guarantees memory safety through compile-time checks, resulting in improved performance and reliability.
