Scraping TikTok's Mobile API

purpose

It is a technical guide documenting how to reach TikTok's private Android mobile API, covering the four requirements for access: device registration, request signing (X-Argus, X-Gorgon, X-Ladon), regional host partitioning, and phone-like TLS handshakes, plus 24 measured endpoints. It also offers full source code and a free 4.5-billion-video dataset on Hugging Face.

when to use

Most valuable when you need fast, reliable, bulk access to TikTok data such as creator profiles, videos, comments, sounds, hashtags, or trending charts beyond what public web endpoints return. Also useful when diagnosing why an existing TikTok scraper silently stores empty responses.

penecho/penecho: Think with AI beyond the chat box. A shared canvas for handwriting, equations, diagrams, and spatial reasoning.

purpose

PenEcho provides a shared 20,000 x 20,000 digital canvas where handwriting, equations, diagrams, and spatial context become part of AI conversations, with answers rendered directly beside your ink. It connects to multiple AI sources (API keys or Kimi, Codex, and Claude CLIs) and supports projects, sharing, and editable AI-generated interactive widgets.

when to use

It is most valuable when working through dense technical problems, visualizing system architectures, deriving equations, or turning research material (PDFs, docs, code) into shareable diagrams and visual workspaces. It shines when chat-based AI interaction is insufficient and spatial, diagram-driven reasoning is needed.

Fasani/three-js-resources: A collection of resources for building 3D projects with three.js

purpose

It aggregates links to free assets (3D models, textures, HDRI, shaders, fonts, sounds), books, browser developer tools, communities, and free software for building 3D projects with three.js.

when to use

It is most valuable when starting or actively developing a three.js/WebGL project and needing free assets, learning materials, debugging tools, or community support.

lukehollis/sphr: Open, hackable 3d digital twin builder that supports 3d gaussian splatting, 360 images, and vfx

purpose

It is a client-rendered viewer/runtime that renders structured SPHR scenes defined in JSON, supporting 3D Gaussian splats (.splat, .ply, .spz, .ksplat, .sog, .rad), 360 panoramas, IIIF image planes, GLB models, annotations, navigation, skyboxes, and guided tours with camera animation.

when to use

It is most valuable when you need to present photorealistic 3D captures, virtual tours, or digital twins on the web without building a custom Three.js rendering pipeline from scratch. It suits projects like architectural walkthroughs, museum/documentation tours, research artifact viewing, or location scanning visualizations.

matthart1983/netwatch: Real-time network diagnostics in your terminal. One command, zero config, instant visibility.

purpose

NetWatch is a zero-config, single-binary terminal UI that provides real-time network diagnostics: live bandwidth monitoring, deep packet inspection of TLS/QUIC/HTTP/DNS, per-connection process attribution, JA4 fingerprinting, and background detection of malware beaconing, port scans, and DNS tunneling.

when to use

Most valuable when debugging slow or failing network interactions, verifying which endpoints an app actually contacts, inspecting encrypted traffic you control, or investigating suspicious outbound traffic during a security incident.

Worktrunk

purpose

Worktrunk is a CLI tool that makes Git worktree management as easy as branch management, offering commands like `wt switch`, `wt list`, `wt merge`, and `wt remove` plus quality-of-life features such as hooks, LLM-generated commit messages, build cache sharing, and CI status display.

when to use

It is most valuable when running 5-10+ parallel AI agents (Claude Code, Codex) on separate tasks, or when juggling multiple concurrent features, hotfixes, or PR reviews that each need an isolated working directory with its own dependencies and dev server.

e2b-dev/E2B: Open-source, secure environment with real-world tools for enterprise-grade agents.

purpose

E2B is an open-source cloud infrastructure that spins up secure, isolated sandboxes where AI-generated code can be safely executed. It offers specialized SDKs for code interpretation, shell command execution, and desktop/computer-use automation (mouse, keyboard, screenshots).

when to use

Use E2B when building AI agents, code assistants, or applications where LLM-generated code must run without risking your host systems, such as data analysis tools, autonomous agents, or browser automation workflows. It's also valuable when you need enterprise-grade isolation and the option to self-host on AWS, GCP, Azure, or your own Linux servers.

fmtlib/fmt: A modern formatting library

purpose

{fmt} is an open-source C++ formatting library that provides a fast, type-safe alternative to C stdio and C++ iostreams. It implements C++20 std::format and C++23 std::print with Python-like format string syntax, positional arguments, portable Unicode support, and an optional header-only configuration.

when to use

It is most valuable when building C++ backend services, CLI tools, or WebAssembly projects that require high-performance logging and output formatting, especially when targeting compilers lacking native C++20 std::format support. Its compile-time format string checking makes it ideal whenever safety against format string errors matters.

The Silo · interactive 3D cutaway

purpose

The site presents a fan-made interactive 3D cutaway model of the Silo from the Apple TV series 'Silo', allowing users to explore its 144 levels in 3D — from the Level 1 wallscreen down to the generator, the digger, and the flooded Silo 17.

when to use

It is most valuable when seeking inspiration or technical reference for building interactive 3D product/spatial visualizations, cutaway or exploded-view experiences, or serverless-hosted 3D web apps.

zyronon/TypeWords: Practice English, one strike, one step forward; 练习英语,一次敲击,一点进步;

purpose

TypeWords is an open-source English learning tool that combines typing practice with vocabulary and article memorization. It offers smart spaced-repetition learning, multiple practice modes (follow-along, dictation, self-test), wrong-word tracking, and built-in vocabulary lists for exams like TOEFL, IELTS, GRE, and CET.

when to use

Use it when you want to improve English vocabulary, spelling, or typing fluency through structured practice with memory-curve-based review. It's also valuable when seeking a real-world Nuxt.js example for building offline-capable, locally-stored educational web apps.
