Fast 2D Rendering on GPU
Previously on my quest for fast rendering of 2D vector graphics on GPU, I have posted a piet-gpu update and a deeper exploration into a sort-middle architecture. These intermediate results showed promise, but fell short of my vision for truly high performance 2D GPU rendering.

High doses of ketamine can temporarily switch off the brain, say researchers
Researchers have identified two brain phenomena that may explain some of the side-effects of ketamine. Their measurements of the brain waves of sheep sedated by the drug may explain the out-of-body experience and state of complete oblivion it can cause.

I Replaced My MacBook Pro with a Raspberry Pi 4 8GB for a Day
Earlier this week, as part of my work doing a more complete review of the Raspberry Pi 4 (coming soon!), I decided I'd go all-in and spend one entire day working entirely (or at least as much as possible) from a Raspberry Pi. And not just doing some remote coding sessions or writing a blog post—that's easy to do on a…

Best practices for managing and storing secrets like API keys and credentials
We have compiled a list of some of the best practices to prevent API key leakage and keep secrets and credentials safe. Secrets management doesn’t have a one-size-fits-all approach, so this list considers multiple perspectives so you can be informed in deciding to or not to implement strategies.

These methods pose a great threat to privacy, however they are limited in one of the
