一、Space & Aerospace Developments

1. SpaceX successfully conducted the 12th Starship flight test, with the vehicle completing a suborbital flight, splashdown in the Indian Ocean, and demonstrating heat shield performance at 1450°C. The launch carried ~45 tons of payload, ranking among the heaviest since the 1973 Saturn V SkyLab launch. Elon Musk noted the test was a critical step toward reusable, low-cost space access and multiplanetary humanity.— via 1 2 3
2. Starlink continued to serve as critical emergency internet infrastructure during disasters, having delivered over 2 million text messages and supported users during hurricanes and wildfires.— via 1

二、AI & Tech Tool Releases

1. Perplexity launched open-source read-only scanning tool Bumblebee to check for malicious packages, extensions, and AI tool configurations on macOS and Linux devices, with integration to trigger deep scans for new supply chain risks via Perplexity Computer.— via 1
2. Garry Tan released gBrain v0.40.0, an open-source shared memory layer for multi-agent systems supporting Gemini Live voice agents, large context handling, and full brain access for Hermes and OpenClaw agents.— via 1 2
3. Yohei Nakajima launched The Founding 500, a $10M fund to support 500 founders building agent-first startups, and introduced a traceable, source-backed research agent built on Active Graph and monid_ai that avoids black-box outputs.— via 1 2
4. Elon Musk announced Grok Build 0.1 can build 5 websites from scratch, added Vercel, Canva, Gamma, and S&P Global Market Data connectors, and rolled out the grok inspect command for configuration checks.— via 1 2

三、Policy & Immigration Debates

1. Paul Graham, Reid Hoffman, and Garry Tan criticized new US USCIS policy requiring green card applicants to apply outside the US, arguing it will force out AI researchers, disrupt families, and harm US tech competitiveness. Critics noted the policy reverses 1960s congressional intent, while USCIS stated exceptions exist for applicants in national economic interests.— via 1 2 3 4
2. Tobi Lutke warned Canada's Bill C-22 (Online Streaming Act) could cost the tech sector billions, citing similar Australian legislation that devastated local tech industries.— via 1

四、Startup & Industry Insights

1. levelsio shared that large tech firms are cutting HR and middle management to adopt AI-assisted developer models, while independent developers now have comparable productivity via AI tools, and that non-technical founders can outpace technical developers using AI and cultural trend awareness.— via 1 2
2. Garry Tan shared startup strategy frameworks: prioritize token count over headcount, build 60% solutions when no alternatives exist, and avoid early automation to accumulate hands-on learning.— via 1 2 3
3. Clifton Sellers noted that long-term pain tolerance is the key metric for scaling a $5M+ annual revenue business, and that AI cannot replace grit, taste, and human connection.— via 1 2

五、Operational & Security Tips

1. levelsio recommended a minimal server security setup: only allow Tailscale for SSH and Cloudflare for web traffic, use Vanilla PHP/JS/SQLite to reduce AI coding errors, and adopt the 3-2-1 backup strategy.— via 1 2 3
2. Nikita Bier announced X will reallocate all view counts to original creators to combat programmatic content reposting for ad revenue share.— via 1
