Firefox: 50G of free VPN every month

Holy shit! I only just found out the Firefox browser gives every user 50G of free VPN traffic per month. Extremely handy for that awkward chicken-and-egg situation. How to use: 1. Type `about:config` in the address bar 2. Go to advanced preferences and click "Show all" 3. Search for `browser.ipProtection.enabled` 4. Flip that entry's value to true

FeedSieve is live on the Chrome Web Store

After many rounds of iteration, FeedSieve — the X-feed cleaner — is officially live on the Chrome Web Store. Who wouldn't want the thrill of one-click blocking those spam accounts? Go for it, folks!

The software list from years of deep macOS use

After years of deep macOS use, here are the pieces of software I've found to be genuinely great: - **QuickRecorder**: a screen-recording gem — tiny, yet powerful. - **ClashParty**: circumvention with the Mihomo core — lots of protocols, fast updates, and a good-looking interface. - **V2rayN**: circumvention with lots of protocols; the UI is a bit dated, but it's stable and free. - **Doubao keyboard**: voice input accurate to a scary degree. Supports macOS, iOS, Android; Windows is on the way. - **Brave**: a privacy-first browser with built-in ad filtering — cleaner than extension-based filtering, and the best companion for watching YouTube. - **Mos**: makes your mouse wheel scroll silky smooth. - **Amphetamine**: keeps your laptop awake with the lid closed — the best companion for vibe coding. - **UU Remote**: NetEase's remote desktop tool, free and fast. With it, what caps the image quality is never the membership — it's your network speed. I usually use it to remote into my Mac from my phone to check vibe-coding results; the key mapping is absurdly efficient. - **Tencent Lemon**: Tencent's Mac junk cleaner — uninstalling apps is smooth, and the menu-bar icon is handy. - **Mole**: the strongest Mac junk cleaner out there — terminal version free, UI version paid. - **Tailscale**: WireGuard-based remote networking. With it, you can reach your little home computer from the ends of the earth. - **Obsidian**: in the AI era, the local-first knowledge management tool. The ecosystem is just too good — pair it with the official Web Clipper browser extension and it works wonders.

We've still developed less than 1% of Cloudflare

I feel like we've still developed less than 1% of Cloudflare. It has shipped way too many features. - Object storage with R2 - Backend API with Workers - AI gateway with AI Gateway - Heavy compute with Container - Caching with KV - Database with D1 - Using PostgreSQL? Hook it up with HyperDrive And that's just the start — the list goes on and on. If you can dream it up, it can probably do it. The kicker is it's genuinely dirt cheap. The free tier alone lasts you a long time. What's a free tier? It means paying zero — a cyber-bodhisattva, an actual saint.

DeepSeek V4 Flash stable release, hands-on: cheap, fast, 1M context, built-in search

A few days deep-diving the stable DeepSeek V4 Flash release: aggressively cheap, lightning fast, 1M context, official built-in web search, fully open source. The one weakness is multimodality — but you can patch it by combining other models.

The First-Party Harness Isn't Always the Best Answer: In the Open-Model Era, Pick Your Model and Harness Separately

Using Claude? Go Claude Code. In the open-model era that instinct deserves an upgrade. The first-party advantage is real, but training a good model and building a good harness are two different kinds of engineering — here's why models and harnesses are now separable choices, plus a positioning map of five harnesses.

Stable, Fast, Productive, Cheap: My AI Coding Stack, Documented

OpenCode + OpenChamber + two DeepSeek V4 Flash subscriptions: 15 projects running code simultaneously and the quota barely moved. The full configuration laid out — context pruning, layered memory, desktop automation, and the "stick with the original pairing" lesson.

Indie developer, tinkering with Cloudflare and AI productivity tools

Former AI product manager, now focused on indie development: combining AI, Cloudflare and content creation into my own products and workflows. Projects, guides and blog posts are the public record of my exploration — if you're doing something similar, let's connect.
