# Been Playing with OpenClaw Source: https://brightonxu.com/posts/en/2026-02-26-playing-with-openclaw/ Author: Brighton (Yi Xu) Published: 2026-02-26 The MacBook keeps proving its worth. ![OpenClaw Pipeline](https://brightonxu.com/img/openclaw-pipeline.png) Anyone who knows me knows that in the second half of last year my main machine switched from the Legion to a MacBook Air M4 — originally just for portability and battery life, plus escaping Ubuntu's disaster-tier desktop performance; sometimes I genuinely do need to reproduce environments, and having a remote box is much more convenient. So now the Legion has become a personal-use Ubuntu 20.04 server bolted to the dorm's ethernet port, trained into pure comfort with tailscale public-net SSH + Claude Code, solving both the no-public-IPv4 situation and native SSH's bad command line (uh, I sometimes really do use CC as a smart command line). The AI agent platform OpenClaw is super hot lately. I took a look and felt it doesn't quite fit into my work pipeline — felt like liberal-arts-major work — but I explored it anyway. Deploying OpenClaw needs a server that can stay online long-term, and what do you know, it got stuffed into the Legion — no Mac Mini purchase needed at all. After playing with it for a while — honestly, still figuring it out. For now I've drafted an initial info-aggregation pipeline that follows tech, finance, and so on, delivered to my tgbot on a schedule every morning and evening. Later I might play with some trading stuff too — maybe give it a few dozen USDT to play with by itself? Or a quant-trading leek's first taste? (My HSBC and ZA are all set up, and I've also secured Mom's massive angel round. Sadly I can't seem to find a suitable api — or rather, the suitable api platforms like ibkr have a "dogs and \_\_\_\_\_ not allowed" sign at the door) On the api side I'm still on z.ai's coding plan. I got bored of lite back then, noticed pro also came with a speed boost, so I upgraded — 90 RMB a month is acceptable. After hooking up the lobster I burned through 100M+ tokens in 2 days; the Zhipu boss must be bleeding so much on me he'll have to ride the bus. The key part is I'm still on the old plan — glm-5 without a weekly cap, its worth rising yet again, 90 bucks delivering 900 bucks of value. I can't even use up the hourly quota, so I gave an api key to a friend's lobster! School has started, but this thing is genuinely fun — a few hours vanish the moment I start playing. I'll keep exploring it when I steal time from being busy; the possibilities really are endless. --- Oh right, here's my current pipeline output — it roughly looks the part. I'm still fine-tuning and adding new toys; the main draw is how convenient designing scheduled tasks is: ![OpenClaw Pipeline](https://brightonxu.com/img/openclaw-link.png) 👇 Click to expand: full sample output of Brighton's little secretary (2026-02-26) ## 📰 Brighton's Little Secretary — Full Digest 🕐 February 26, 2026 01:52 GMT+8 (Refresh) ### 🔥 Top Stories (Deep Analysis) **【NVDA earnings tonight: the biggest test for the AI market】** • "Nvidia's earnings report comes at a critical time for the US stock market with investors increasingly nervous about the outlook for artificial intelligence" • "The tech-heavy Nasdaq 100 rose 1.2% ahead of earnings" • "More than solid results and forecasts, Nvidia will need to manage expectations around the sustainability of margins amid an AI spending frenzy" 📊 **Key figures:** • Option-implied volatility: just 5.6% (the lowest in three years) • Market expectations: EPS $1.53, revenue $65.8B • Key watchpoints: Blackwell shipments, China revenue, and gross margin 💡 **Deep read:** NVDA's current market cap is $4.5T, roughly 6.7% of the S&P 500.
