Hands-on guides, protocol deep dives, and field notes on tunnels, SSH, reverse proxies, self-hosting, self-hosted LLMs, and AI - from the people building Pinggy.
A practical comparison of Funnel.io, Coupler.io, Fivetran, Airbyte, and Supermetrics: connector coverage, ELT vs marketing-first workflows, self-managed vs fully managed pipelines, and entry pricing from $24 to $300 a month.
How AI avatar generation moved from 2D mouth warping like Wav2Lip, through 3D morphable models and neural rendering, to audio-conditioned latent diffusion - with the trade-offs, the bottlenecks, and what to stress test before picking an engine.
Your ISP put you behind Carrier-Grade NAT, so port forwarding is dead. Here is how to reach Home Assistant, Frigate, Zigbee2MQTT, ESPHome and Node-RED from outside the house using an outbound tunnel, including the trusted_proxies settings that Home Assistant needs before it will answer.
Long-horizon agent runs fail for structural reasons, not intelligence reasons. Here is what actually holds a multi-hour agent workflow together: a written success contract, separated discovery and delivery phases, persistent state outside the context window, external test oracles, checkpoints, and hard limits on autonomy.
Apple's M5 Ultra Mac Studio tops out at 512GB of unified memory at 1.2TB/s. Here is the memory math, which large open-weight LLMs actually fit, measured tokens per second, and three ways to run a model bigger than 4-bit allows: Unsloth GGUF quants, streaming weights off SSD, or a Thunderbolt 5 cluster.
git.kernel.org now spends more CPU rendering pages for AI training scrapers than on every git clone and legitimate visit combined. Here's what the numbers say, why proof-of-work challenges like Anubis are winning and losing at the same time, and what it means for anyone running their own infrastructure.
A practical technical guide to diagnosing email deliverability issues with DNS. Learn how to verify MX, SPF, DKIM, and DMARC records using terminal commands, fix duplicate SPF records, and ensure your emails reach the inbox.
How to debug VoIP calls, SMS delivery, and phone number verification: locate the point of failure, read API responses and logs, separate signaling problems from media problems, test webhooks on their own, and trace verification codes end to end.
A practical checklist for reviewing an all-in-one AI tools subscription before you buy: what's actually included, testing it against real work, output quality, usage limits, team access, and privacy controls.
How student developers can test a mobile app backend from any building on campus: local vs cloud vs hybrid setups, secure tunnels through campus Wi-Fi, a repeatable testing workflow, and the network, auth, and configuration bugs that only appear away from the lab.
