5Prompt engineering playbook for programmers
- The article explores effective prompt engineering strategies for AI coding assistants. It emphasizes providing clear context, being specific with requests, breaking down complex tasks, and using examples. The guide covers principles for crafting prompts that yield better code solutions and debugging assistance from AI tools.
Prompt engineering techniques
Discussion of core prompt engineering methods, focusing on in-context learning, chain of thought, and structured output. Debate over whether role prompting and complex prompts are useful vs simple instructions.Simple vs complex prompts
Arguments that shorter, simpler prompts often work better than elaborate ones. Many users report converging on minimal prompts through experience, though some note certain technical contexts need more detail.Engineering title debate
Controversy over whether "prompt engineering" deserves the engineering title. Some argue it's just writing clear instructions, others defend it requires systematic testing and optimization processes.
6Google restricts Android sideloading
- Google has restricted Android app sideloading in Singapore for security, partnering with their Cyber Security Agency. This move limits app installations outside the Play Store to prevent fraud, but critics argue it reinforces Google's control. Purism offers an alternative with privacy-focused PureOS and Librem phones.
Singapore's scam problem
Discussion of how Singapore's affluent, digitally advanced population is particularly vulnerable to scams, losing S$1.1bn in 2024, leading Google to implement these restrictions in partnership with local authorities.Technical workarounds
Debate about using GrapheneOS and other technical solutions to bypass restrictions, with critics noting these aren't practical for average users and Google's Play Integrity API blocking even secure alternatives.Impact on legitimate uses
Concerns about how restrictions affect legitimate sideloaded apps, particularly accessibility tools like Commentary screen reader for blind users and specialized apps not available in Play Store.
7The impossible predicament of the death newts
- This fascinating evolutionary tale describes the arms race between the Rough-Skinned Newt and garter snakes in the Pacific Northwest. The newts produce tetrodotoxin for defense, while snakes evolve resistance and eat the newts to become toxic themselves, creating a complex predator-prey relationship that continues to evolve.
Evolution and adaptation costs
Debate about whether evolutionary traits like toxin resistance necessarily come with biological costs. Some argue traits are simply retained when beneficial, while others contend metabolic costs must exist.Snake-newt interaction
