Making MCP cheaper via CLI

https://kanyilmaz.me/assets/posts/cli_vs_mcp.png
MCP overcharges by dumping entire tool catalogs upfront, while CLI and Anthropic's Tool Search use lazy loading to reduce costs. CLI is cheaper and works with any model, while Tool Search is Anthropic-only and more expensive.

Origin of the rule that swap size should be 2x of the physical memory

https://retrocomputing.stackexchange.com/Content/Sites/retrocomputing/Img/apple-touch-icon@2.png?v=6b27f39a6023
The origin of the 2x swap size rule is unclear, but it likely originated from the 4.3BSD virtual memory implementation and was influenced by the need for contiguous block allocation on disk. The rule is a rough estimate, partly psychological and partly technological, aiming to ensure that roughly the same amount of RAM is swapped out as physical RAM, with the goal of allocating contiguous ...

Learnings from 4 months of Image-Video VAE experiments

https://www.linum.ai/vae-reconstruction-vs-generation/high_quality_reconstructions/images/042_original_resized.jpg
Researchers built an Image-Video VAE to compress images and videos into a compact latent space for diffusion models, but found that better compression doesn't always track with VAE stability or downstream generation quality. They discovered that over-optimizing reconstruction quality can hurt the model's chance to disentangle data into a semantically meaningful space, and that aligning the ...

Dissecting the CPU-memory relationship in garbage collection (OpenJDK 26)

https://norlinder.nu/assets/img/stopwatch.png
The traditional pause time metric for measuring garbage collection (GC) performance is no longer sufficient due to the increasing complexity of modern GC algorithms and the decoupling of pause time from machine resources. A new Java API and unified logging mechanism in OpenJDK 26 provide a precise and internal accounting of the collector's work, enabling developers to understand the ...
