SQLite was thought of as a toy for many years until we all realized it was actually nice to use a database as a library, even server-side. And yet...

1. It's a big dependency, despite what you think. In no universe is 150,000 lines of C code "lightweight".
2. Like with all SQL databases, you have an impedance mismatch: the way you store data in memory is completely different than the table structure a SQL database forces on you, leading to tons of glue code.
3. It's mutable, so it can't undo or time travel, and it can't read while a write is happening (even in WAL mode...reads can't happen during checkpointing!).

To solve these problems, I'm building a database called xitdb. It has ports for several languages:

• Zig: radarroark/xitdb
• Java: radarroark/xitdb-java

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

Cloudflare

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k

Organize Images into folders using AI

This is a tool that sorts images into folders using "AI". You create the folders you want the images to be put into.

I got 'claude' to write with a couple prompts. Make venv and install deps with pip.

• Use microsoft/git-large-coco To turn images into short descriptions of images - https://huggingface.co/microsoft/git-large-coco
• Use all-MiniLM-L6-v2 to turn short descriptions into 'embedding vectors' - https://www.sbert.net/docs/sentence_transformer/pretrained_models.html
• Compare the embedding vector of the image, with the embedding vectors of the folders - choose the best folder to put the image into
