How to use these tihngs.

Like most people, I have had success with splitting things into a planning stage followed by an implementation stage. The implementation phase can be kind of synchronous/interactive, or can be a fully auto Ralph loop.

atproto-pds: Foundational Design Document for a Rust ATProtocol Personal Data Server

Author of design brief: Nick Gerakines (CTO, Graze Social; founder, Smoke Signal & Lexicon Garden; author, AIP OAuth server; AT Protocol Community Fund member). Target home: tangled.org/ngerakines.me/atproto-crates, as a new crate atproto-pds. Date: May 1, 2026 (revision 2). Architectural North Star: A low-latency, highly-performant Rust PDS that is fully conformant to the existing reference implementations and is architected from day zero to support permissioned data spaces as a first-class concern, grounded in the concrete design laid out in bluesky-social/atproto/docs/superpowers/specs/2026-04-22-permissioned-data-pds-design.md (Daniel Holmgren's PDS implementation design, hereafter "the Spaces Design Spec"). The Spaces Design Spec supersedes the earlier Permissioned Data Diary blog posts as the authoritative source for protocol mechanics; the diary is retained only as conceptual backgr

Handling The inferred type of x cannot be named without a reference to y

This error is notoriously fickle to reproduce or resolve. It can always be fixed by adding an export type for a name TS needs to compile your types. Here's how to find where the change needs to be made:

1. Navigate to the source of the diagnostic in the repo's _tsc.js file (line 52151 as of TS 5.7.3). You can search for reportLikelyUnsafeImportRequiredError to see all references to it if needed. Add a breakpoint in at that position:

if (!attributes) {
  // ADD BREAKPOINT HERE ⬇️
 context.encounteredError = true

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

Bevy + egui in a text-based, turn-based adventure game.

I won't go too far into the nitty details (lol), but this is generally how I've structured my WIP mostly-text-based, turn-based adventure game. I emphasize that because I suspect this approach doesn't work all that well for other styles of games. Specifically, because practically everything in my game happens on-click; there's very little running in the background.

TL;DR?

Nah, I strained my eyes for this.

Implementing complex numbers and FFT with just datatypes (no floats)

In this article, I'll explain why implementing numbers with just algebraic datatypes is desirable. I'll then talk about common implementations of FFT (Fast Fourier Transform) and why they hide inherent inefficiencies. I'll then show how to implement integers and complex numbers with just algebraic datatypes, in a way that is extremely simple and elegant. I'll conclude by deriving a pure functional implementation of complex FFT with just datatypes, no floats.
