How to Build a Remote Job Alert System (No API Key Required)

The Problem with Job Board Notifications Most job boards have email alerts, but they're noisy and limited. You can't filter by salary range, tech stack, or specific keywords in the description. You can't combine alerts from multiple boards into one feed. And you definitely can't pipe the results into your own tools. Let's fix that. In this tutorial, we'll build a remote job alert syste...

Exploring Elyan Labs: Open-source infrastructure for vintage silicon

I recently looked into Elyan Labs and found their approach to hardware infrastructure quite interesting. They are focusing on the intersection of vintage hardware and open-source development, integrating "Proof of Antiquity" concepts within the RustChain blockchain. What caught my attention: Infrastructure focus: 44+ PRs contributed to core projects like OpenSSL, Ghidra, vLLM, and LLVM. Researc...

3 Things I Learned Benchmarking Claude, GPT-4o, and Gemini on Real Dev Work

If you're still picking LLM providers by gut feeling, you're leaving money on the table. I ran 5 developer use cases through Claude 3.5 Sonnet, GPT-4o, and Gemini 2.0 Flash using PromptFuel to measure token usage and cost. The results? More interesting than "fastest wins." Here's what I found. The Setup I took 5 tasks I actually do in PromptFuel development: JSON schema validation p...

AI Agent Observability: Debugging Production Agents Without Going Insane (2026)

The first time I shipped an AI agent to production, I watched it do something in the logs that I could not reproduce locally, could not explain, and could not fix. A user asked it to summarize a meeting. It responded with a confident paragraph that referenced three people who were not in the meeting, a decision that was never made, and a date that did not exist. Everything about the response look...

Why I Returned to Coding After 7 Years as a "Pure" CEO

In the Pre-AI era, a responsible CEO had three jobs: Raise money, recruit talents and set the vision. If you spent your day writing code, you were "irresponsible." You were indulging in your own joy while neglecting the ship's direction. I followed this rule and stopped coding six or seven years ago to focus entirely on strategy. The AI Pivot: Late last year, I went All-in on AI. Everything chang...

I Built the World's First IPv8 Firmware Stack — Here's Why We Should Skip IPv6

IPv6 is 30 years old. It still carries less than half of global internet traffic. 91.4% of IoT devices break on IPv6-only networks. And the industry keeps pretending the migration is "right around the corner." What if we just... skipped it? The IPv6 Problem Nobody Wants to Admit In 1994, the IETF started designing IPv6 to fix IPv4 address exhaustion. Thirty years later: Global adopt...

The SSML Basics Every Creator Should Know

You paste a script into a text-to-speech tool, hit generate, and the result sounds… flat. The pacing is wrong, emphasis lands on the wrong syllable, and your carefully chosen words blur together into a robotic drone. You know the content is good. The delivery just isn't there yet. That gap between "readable" and "listenable" is exactly what SSML closes. Speech Synthesis Markup Language is a W3C s...
