Win16 Memory Management

http://www.os2museum.com/wp/wp-content/uploads/2026/06/windev-30-wlk-1-640x480.png
16-bit Windows used a segment-based memory management system, where applications were divided into segments that could be moved or discarded by the operating system, requiring programmers to use specific compiler switches and APIs to manage memory correctly. The system was complex and required discipline from programmers, but it allowed for efficient memory management and the use of ...

Speculative KV coding: losslessly compressing KV cache by up to ~4×

Speculative KV coding is a lossless compression method for large language model (LLM) caches, using a predictor model to estimate the cache's values and an arithmetic coder to encode the differences. The method can achieve up to 8x compression on original bf16 caches and stacks multiplicatively with lossy quantization.

To maintain the codebase, we focused on designing environments, scaffolding, and feedback loops that enable agents to do reliable work, enforcing invariants and mechanical rules to keep the codebase legible and consistent.

How Long Does It Take for a QQuickItem to Become Visible?

https://eu-central-1.linodeobjects.com/wagtail-production/images/Frames_skipped_counter_in_application.width-300.png
How long does it take for an Item that you’ve just loaded to become visible? Answering this question allows for a way to detect what some users would perceive as "frame drops". I write that in quotes because Qt Quick only draws frames when needed, meaning it doesn't drop frames; but it can show them later than one would expect. That is what we would like to identify: When ...

Moving beyond fork() + exec()

A recent Linux kernel proposal to add "spawn templates" to optimize the fork() and exec() pattern has been rejected, but it may point to a new process-creation primitive in the future. The discussion highlights the need for a better process-creation mechanism, with some suggesting a native implementation of posix_spawn() and others proposing alternative approaches using existing system calls.

Arithmetic Without Numbers – How LLMs Do Math

https://alvaro-videla.com/llm-arithmetic-internals/article_interactive/assets/blender_integer_helix.png
A language model can perform arithmetic operations without explicit programming, but the question is whether it recalls a pattern, runs an algorithm, or merely produces a plausible next token. The project Rune found that a language model's internal state can supply operation and operand structure for arithmetic prompts, which can drive a calculator route under an opaque-prompt boundary.
