Whosthere
Whosthere is a Go TUI/CLI tool that discovers devices on a local area network using mDNS, SSDP, and ARP scanning without requiring root privileges. It's a practical home network visibility tool that also runs as a headless daemon with a simple HTTP API.
Wiredoor: Self-Hosted Ingress with SSL and VPN
Wiredoor is a self-hosted ingress-as-a-service platform that exposes private services over the internet via a WireGuard-powered reverse VPN — SSL included. It's a self-hostable Ngrok/Cloudflare Tunnel alternative with IoT and Kubernetes support.
ESP32 WiFi Superstitions
Three practical workarounds for ESP32 WiFi disconnection problems: disable power saving mode, limit 2.4GHz channels to 20MHz width, and pin devices to specific access points. Admitted to be 'superstitions' without rigorous basis, but proven effective in practice.
Bjorn: Raspberry Pi Network Scanner with e-Paper Display
Bjorn is a network scanning and offensive security tool for Raspberry Pi with a 2.13-inch e-Paper HAT display — discovers targets, identifies open ports and vulnerable services, and shows results on the tiny screen. A self-contained portable pentesting device for the hobbyist security researcher.
Internal Constrained PKI: Safe TLS CA for .internal Networks
internal-constrained-pki creates a TLS root CA for .internal networks with X.509 Name Constraints — the CA is cryptographically prevented from signing certificates for public domains, making it safe to share with team members without compromising internet trust.
How to Write a Cold Email
Sriram Krishnan's guide to writing cold emails that get responses — focused on the fundamentals of making a good ask without wasting the recipient's time. Practical advice from someone on both ends of many cold emails.
South Park Commons: The Modern Junto Club
Wired's profile of South Park Commons, a San Francisco community for technologists in transition — people between jobs, exploring new ideas, or building something new. Framed as a modern Junto Club where learning together precedes building together.
Orchid: Decentralized VPN Marketplace
Orchid is a decentralized VPN marketplace where users pay for bandwidth with OXT tokens on Ethereum — an attempt to build a censorship-resistant, market-driven alternative to traditional VPN providers. Interesting experiment in crypto-native privacy infrastructure.
Home Lab Beginners Guide: Hardware
A beginner's hardware guide to setting up a home lab — covers server options (used enterprise gear vs. mini PCs), networking basics (managed switches, VLANs), and storage. Entry point to the homelab community's approach to learning infrastructure hands-on.
DNS Paper (April 2022)
A paper on DNS (Domain Name System) saved in April 2022. The Unix timestamp in the filename (1649775033 = April 12, 2022) suggests it was auto-named at download time. DNS research spans security (cache poisoning, DDoS amplification, DNSSEC), privacy (DNS-over-HTTPS, DNS-over-TLS), and infrastructure reliability.
Enclave: Zero-Trust Overlay Networking
Enclave is a zero-trust overlay networking product that creates software-defined private networks between machines without VPN infrastructure — each machine gets a cryptographic identity and point-to-point encrypted tunnels replace network perimeters.
Nat: Personal CRM for Relationship Building
Nat is a personal CRM focused on relationship building rather than sales pipelines — tracks when you last spoke to people and surfaces who you should reconnect with. The anti-Salesforce for personal networks.
SmoothWAN: Router for Speedify WAN Bonding
SmoothWAN is an OpenWrt-based router firmware that makes setting up Speedify for WAN bonding simple — combining multiple internet connections (4G, cable, DSL) for higher bandwidth and resilience. A practical project for anyone with unreliable internet.
Tunneling Tunnels: Multi-Hop VPN with Multitun
cryptostorm's writeup on multitun — nesting multiple VPN tunnels inside each other for layered anonymity. The multi-hop VPN pattern separates entry and exit knowledge, so no single provider can link your identity to your traffic.
Enabling SSL in Your Local Network
A practical approach to getting proper SSL certificates for local network services using Let's Encrypt wildcard certs and DNS validation — avoiding the browser warnings of self-signed certs without exposing services to the internet. Clean solution for anyone running internal homelab services.
Netmaker: WireGuard Network Automation
Netmaker automates the creation of fast, secure, distributed virtual networks using WireGuard — with an admin UI, access control, private DNS, and support for mesh, site-to-site, and Kubernetes networking. More featureful than Headscale, trades simplicity for capability.
Headscale: Self-Hosted Tailscale Control Server
Headscale is an open-source, self-hosted implementation of the Tailscale control server — the missing piece that lets you run a fully private Tailscale network without depending on Tailscale's managed infrastructure. The self-sovereignty option for Tailscale users.
Intel Wants to Kill the Traditional Server Rack with 100Gbps Links
Ars Technica on Intel's push to replace copper Ethernet in server racks with 100Gbps silicon photonics links — the argument that data center networking bandwidth was the bottleneck for distributed computing in 2013. Intel's bid to own the rack interconnect layer.
Aaron Swartz: howtoget
Aaron Swartz's notes on how to get what you want — a short, frank guide to the mechanics of creating opportunities, from reaching out cold to the right people to learning by doing. Characteristically blunt.
Configuring Wireless LAN on Raspberry Pi with RTL8188CUS WiFi Dongle
A 2012 setup guide for adding WiFi to the Raspberry Pi using the RTL8188CUS USB dongle — one of the first supported cheap WiFi adapters. The Pi had no built-in wireless until the Pi 3 in 2016, so USB dongles were required for years.
Mellanox Introduces RDMA-Based Virtual SAN Software Appliance
Mellanox announced a Virtual SAN software appliance built on RDMA that claimed 6x the performance of traditional Fibre Channel SAN hardware. A signal that software-defined storage was coming for legacy enterprise SAN.
Mosh: The Mobile Shell
Mosh (mobile shell) is a UDP-based replacement for SSH that maintains connections across network changes, provides instant local echo even on high-latency links, and never drops a session when you close your laptop. The right tool for anyone working over unreliable or mobile connections.
MegaPath / Speakeasy network outage, 2009
A 2009 bookmark of MegaPath's network coverage page, saved with a note about Speakeasy having nationwide connectivity issues in NorCal. An ephemeral ISP troubleshooting bookmark from the college years.
