This piece teaches you five fingerprints for spotting hollow content, a thirty-second wallet check, and six thinking habits you can practice daily — write down a dated prediction, explain it plainly, write your own answer first, ask how a claim could be falsified, think one step further, and cool off for 48 hours.

Six phases, fully local, full prompt included for copy-paste. This is my run — including the part where my own records called my bluff.Mon, 13 Jul 2026 00:00:00 GMThttps://blog.getrealpha.com/en/blog/certainty-for-sale/https://blog.getrealpha.com/en/blog/certainty-for-sale/A colleague started following a large Taiwanese stock-tutorial channel, and I didn't read it as poor judgment on his part. What he's buying isn't financial knowledge—it's the feeling that the market can be understood, predicted, and controlled. This piece uses behavioral finance and media literacy to unpack the six psychological needs these channels target so precisely, the free-trust-to-paid-course marketing funnel, and three questions you can carry with you to test any of them. An educational reflection—no channel is named, not investment advice, disclaimer at the end.Mon, 13 Jul 2026 00:00:00 GMThttps://blog.getrealpha.com/en/blog/gooaye-ep678-when-the-fog-lifts/https://blog.getrealpha.com/en/blog/gooaye-ep678-when-the-fog-lifts/Personal notes on Gooaye EP678: Meta repurposing old GPUs for inference and renting them out — refuting the 'AI server bad-debt' short thesis while making compute pricing transparent, which pressures dream-multiple valuations; rotation inside optical communications; the broad component price-hike wave.

In our last two days, I didn't ask it to do more work — I asked it to write down its thinking process. It left a map of my life's key problems, ten crisis playbooks, an honest gap map, and a letter. This is the record of those two days, and what I learned.Sun, 12 Jul 2026 00:00:00 GMThttps://blog.getrealpha.com/en/blog/ai-team-orchestration/https://blog.getrealpha.com/en/blog/ai-team-orchestration/How a one-person AI company actually works: let Claude be the head coach that plans the hard problem and nails the interface, hand the execution to OpenAI's GPT-5.6 and a suddenly-sharper xAI Grok 4.5 running in parallel, then verify against reality. Three days of multi-vendor AI teamwork, shared as method and reflection.Sat, 11 Jul 2026 00:00:00 GMThttps://blog.getrealpha.com/en/blog/caibaogou-ep538-anti-bubble-and-leverage/https://blog.getrealpha.com/en/blog/caibaogou-ep538-anti-bubble-and-leverage/Personal notes from Statementdog (財報狗) Podcast EP538: anti-bubble thinking, Korea's memory deleveraging, memory prices slowing but supply still tight, firms starting to rein in AI spend, and compute going tiered-and-cheaper.

X gives you the fastest information — and it's also where you most need to separate signal from noise.

This is my attempt to run Grok 4.5 inside Claude Code and still bill it to my subscription, the grey-zone path I found, and the four-question security audit I ran on a third-party tool before letting it hold my account token. Tech notes and hands-on lessons, not a how-to.Thu, 09 Jul 2026 00:00:00 GMThttps://blog.getrealpha.com/en/blog/grok-claude-code-three-paths/https://blog.getrealpha.com/en/blog/grok-claude-code-three-paths/The OAuth cliffhanger from last time, resolved. A diagnostic mistake — reading a personal subscription as a team account — sent me the long way round; once cleared, there turned out to be three ways to run Grok in (or next to) Claude Code, each with a price. But the real takeaway isn't 'I found the method' — it's rethinking how to allocate tasks: unattended automation rides the stable billing path, and only human-in-the-loop work rides the cheap subscription path.
