"Disregard That" Attacks

https://calpaterson.com/images/screenshots/disregard-that.png
Large Language Models (LLMs) are vulnerable to "Disregard that!" attacks, where untrusted input can be injected into the model's context window, leading to security issues. The problem cannot be solved by adding more agents or using AI guardrails, and the only effective mitigation is to not allow untrusted input into the context window.

Apple randomly closes bug reports unless you "verify" the bug remains unfixed

You file bug reports with Apple Feedback Assistant due to a mix of addiction and the occasional fix of reported issues. However, Apple's lack of response and apparent disregard for users' time and effort is a major complaint.

Quantization from the Ground Up

https://ngrok.com/blog-assets/images/2026-03-25-quantization/og.jpg
Sam Rose discusses how to make large language models (LLMs) smaller and faster by reducing the number of parameters and using quantization, a process that reduces the precision of floating-point numbers. By applying quantization techniques, such as symmetric and asymmetric quantization, LLMs can be made 4x smaller and 2x faster with only a 5-10% loss in accuracy.

Thoughts on slowing the fuck down

https://mariozechner.at/posts/2026-03-25-thoughts-on-slowing-the-fuck-down/media/header.png
The author warns that relying on coding agents can lead to brittle, complex, and unmaintainable codebases due to their inability to learn from errors and lack of global understanding. To avoid this, humans should slow down, use agents for non-critical tasks, and maintain agency over their codebases to ensure quality and maintainability.
