Slow typing has long been my productivity bottleneck. Writing articles, replying to emails, capturing ideas — it’s not that my brain can’t keep up, it’s my fingers can’t. Until I started using Typeless. What is Typeless Typeless is an AI-powered voice input tool that supports macOS, Windows, iOS, and Android. The core idea is simple: you speak, it writes. Unlike clunky speech recognition from a decade ago, Typeless layers AI on top: ...

Speech recognition technology itself is already mature, but the real reason it falls short in practice isn’t accuracy—it’s that the transcribed text isn’t immediately usable. Typeless positions itself as an AI layer on top of speech recognition, making the output directly practical. This post breaks down several of its core features. Auto-cleanup: removing filler words and redundant expressions This is Typeless’s most fundamental and practical feature. ...

Most people have tried voice input and given it up—what comes out is a jumbled mess, takes time to clean up, and ends up slower anyway. That’s the old voice recognition problem. Typeless adds an AI layer on top of transcription to polish it, which basically solves it. From using it, three scenarios stand out. Scenario One: Drafting Technical Articles The most time-consuming part of writing technical articles isn’t typing—it’s the “from idea to first draft” phase. You have the structure in your head, but translating it into words hits a wall. You keep deleting and rewriting, and the whole thing just slows down. ...

Running OpenClaw with default config will hit two problems after a while: quota burns too fast and long sessions crash from timeouts. This post logs 8 parameters I actually tuned, and the reasoning behind each. Architecture First Here’s my setup: GitHub Copilot Pro+: $19/month, 1500 premium requests/month quota Claude Opus 4.6: accessed via Copilot’s model routing, model ID github-copilot/claude-opus-4.6 OpenClaw: handles Telegram interactions, Skill calls, scheduled tasks Quota math: each AI assistant reply = 1 premium request (including replies after tool calls). 1500 sounds like plenty, but without optimization it dries up fast. ...

Xray’s VLESS+XTLS-Reality is widely recognized as the most robust protocol combination for anti-censorship. Its core principle is disguising traffic as a normal TLS handshake, making it difficult for the GFW to identify proxy traffic through signature detection. This guide walks you through deploying a fully functional setup from scratch. Prerequisites An overseas VPS (I recommend DMIT Hong Kong or US nodes for excellent routing quality) VPS OS: Ubuntu 22.04+ Local client: mihomo (formerly Clash Meta) Server Deployment Install Xray bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install Generate XTLS-Reality Keys xray x25519 Output: ...

You’ve bought a VPS and written quant strategy code, but how do you get it to “run automatically” and “tell you what’s happening at any moment”? That’s where most people get stuck. I solved this with OpenClaw. What is OpenClaw Simply put: a framework that lets AI assistants call various tools. Its core capabilities are: Provides CLI tools (openclaw message send) to send Telegram/Discord messages from any script Has a Skill system to equip AI with various capabilities (GitHub, Notion, weather, custom scripts) Supports cron scheduled tasks and remote triggering For quant trading, the most useful part is message push notifications. ...

Writing Quant Strategies with Claude Building quant strategies has a high barrier to entry: you need to understand trading logic and write code. Claude cuts that barrier in half — you just need to know the trading logic, and it handles the code part. This article documents my process of building a complete quantitative signal system from scratch with Claude. ...

IP blocks are a common issue for proxy nodes, and I’ve dealt with it many times. This article outlines the complete troubleshooting process. Step 1: Confirm If It’s an IP Block or Something Else When you can’t connect to a node, first rule out non-blocking causes: # Test IP connectivity from mainland China (use mobile hotspot to rule out local network issues) ping your_VPS_IP # Test if the port is open nc -z -w5 your_VPS_IP 443 && echo "open" || echo "blocked" Common confusion cases: ...

OpenClaw Intro & Setup If you’ve used Claude Code, you can think of OpenClaw as its “async version”—Claude Code is great when you’re sitting at your computer working interactively, while OpenClaw is designed to let AI help you continuously in the background, even when you’re away from your desk. What OpenClaw Is Actually For One sentence: Give your AI assistant the ability to access and operate external tools, and interact with you through Telegram and other channels. ...

I’ve hit plenty of pitfalls choosing VPS providers. This article shares providers I’ve actually used — straight conclusions, no fluff. VPS Selection: Core Metrics VPS for proxy tunneling is different from standard hosting. There are three core metrics: Latency: Ping to mainland China — lower is better Stability: How likely is the IP to get blocked, and how much line jitter do you see Exit quality: CN2 GIA > standard BGP; direct peering > relay DMIT: My Current Primary I’m using DMIT nodes in Hong Kong and the US, and I’ve been happy with them for about a year. ...

⚠️ Registration Requirements: Pionex doesn’t support mainland China ID cards for KYC verification. You’ll need a valid ID from Taiwan, Singapore, Malaysia, the US, or similar jurisdictions. See Pionex’s official restricted regions notice. Grid trading looks the same on the surface, but the differences between Pionex and Binance are bigger than most people realize. I use both, so here’s my breakdown of how to choose. ...

Using OpenClaw for automation—the real headache isn’t configuration, it’s when things mysteriously stop working mid-run. This post covers the failures I’ve hit and their fixes. Gateway Issues Gateway Service Won’t Start Symptoms: Telegram messages go unanswered, AI assistant doesn’t reply. Check: openclaw gateway status Common Causes & Solutions: Cause Solution Process crashed openclaw gateway restart Bot Token expired Get a fresh token from BotFather, update config Port conflict Use lsof -i :port to find what’s using it, kill it Windows won’t auto-start on boot Add to Task Scheduler for startup Windows Caveat: On Windows, Gateway doesn’t auto-start with the system. After each reboot, you need to manually launch it: ...
