Things Unix can do atomically (2010)

UNIX-like/POSIX-compliant operating systems provide atomic operations for thread-safe and multi-process-safe programs without mutexes or locks. These operations include mv -T, link, symlink, open, mkdir, and fcntl, which can be used for file and directory locking, creating new files and directories, and synchronizing access to files.

Unlocking high-performance PostgreSQL with key memory optimizations

https://stormatics.tech/wp-content/uploads/2025/10/Postgres-backend-1-1024x683-1.webp
To optimize PostgreSQL performance, understand settings like shared_buffers and work_mem, which control memory usage and disk interaction, and adjust them based on real metrics and system statistics. Properly sizing shared_buffers (20-25% of total RAM) and work_mem (3-4MB per GB of RAM) can prevent memory pressure, disk spills, and out-of-memory errors.

How to carry more than your own bodyweight (2025)

https://ichef.bbci.co.uk/images/ic/480xn/p0kmchqx.jpg.webp
Some communities have developed techniques to help them carry heavier loads. Here's what we can learn from them. The rural farm workers of Vietnam could be seen as almost superhuman. Every day, they shoulder impressive loads strung to a pole before carrying them for up to several miles at a time by foot. The awkward, bulky packages of produce, tools or other materials can often weigh more ...

Review of 1984 by Isaac Asimov (1980)

Aaronson reflects on how he was not alone in being approached by Epstein, but notes that many scientists who interacted with him were either charmed by him or prioritized his funding over their reservations.

Hypernetworks: Neural Networks for Hierarchical Data

https://blog.sturdystatistics.com/posts/hnet_part_I/title-image.png
Standard neural networks fail to handle hierarchical data where observations are grouped into distinct datasets with hidden parameters, leading to flawed conclusions and overfitting. Hypernetworks offer a solution by learning to generate dataset-specific parameters based on a dataset embedding, enabling flexible and data-efficient adaptation while pooling knowledge across datasets.

Generative Pen-Trained Transformer

https://avatars.githubusercontent.com/u/48384497
A few years ago, back when GPT-3.5 was first released, and I still spent most of my days sitting in a high school classroom, I had a project idea. Perhaps one of my best named project ideas to date: The Generative Pen-trained Transformer or GPenT for short. GPenT was awesome, I was going to build out a color-changing pen plotter with some funky coreXY-esque kinematic, and alongside it, try my ...
