This piece highlights four practical uses: 1) Crypto and traditional investing: AI analyzes massive data, spots patterns, automates trading strategies, and provides predictive analytics and portfolio optimization. 2) Real-time investment insight: AI can forecast stocks and help traders make better decisions as data flows in. 3) Skill growth and career leverage: AI feedback helps you learn new skills, advance your career, and increase earnings. 4) Sales efficiency and expansion: AI reviews calls, identifies bottlenecks and objections, and delivers feedback (e.g., to Slack), boosting close rates and revenue. In short, AI processes vast data, reveals patterns, automates tasks, and accelerates wealth-building.

At 2.5m, it supports 112G PAM4 signaling and pairs an 800G OSFP end with two QSFP112 connectors. The finned OSFP design embeds cooling in the connector, enabling eight 112G PAM4 lanes (8x 100Gbps) to deliver practical 51.2Tbps switching with 64-port 800GbE. The cable can split an 800G port into two 400G ports, effectively mapping 8x112G PAM4 into two 4x112G channels per end. The article notes the distinction between QSFP112, QSFP56-DD, and QSFP28, and explains why 400G speeds often require multiple PAM4 lanes. It concludes that while DACs are common, the 800G era adds complexity and varied form factors (finned/flat top OSFP).

The Air options keep budget-friendly starts at $999 (13-inch) and $1,199 (15-inch), while the Pro begins at $1,599 for the 14-inch. Key differences include the display (Air: LCD, 60 Hz; Pro: Mini-LED, up to 120 Hz ProMotion, brighter), cooling (Air: passive; Pro: active), ports (Air: 2 TB4; Pro: 3 TB4 + HDMI + SDXC), and speakers/mics (Air vs Pro with studio array). Battery life: Air up to 18 hours vs Pro up to 24 hours. The Pro also brings a larger, higher-end chassis, and the M5 promises up to ~15% faster CPU, ~30% faster graphics, and better ray tracing. Which model fits your workload and budget?

October 25, 2025, 5:28 PM EDT. Tesla investors are blasting Elon Musk's proposed compensation as the most absurd pay package in corporate history. Critics cite arbitrary vesting tranches and potential Delaware issues, noting looming lawsuits and questions about governance that truly checks Musk, who speaks of a robot army. Some fear societal risks if he stays or leaves, arguing the board is too cozy to push back. The debate centers on governance, board independence, and whether a massive pay package aligns with long-term shareholder value at Tesla.

October 25, 2025, 5:26 PM EDT. A widespread AT&T DNS outage disrupted internet access for thousands nationwide, starting just before midnight ET Friday. Downdetector reports and outage maps show problems across major cities and regions, with users citing DNS lookup failures and slow connections. The issue manifested as the DNS_PROBE_FINISHED_NXDOMAIN error, indicating a Domain Name System failure. Some users resolved problems by flushing DNS caches or switching to public DNS services like Google DNS (8.8.8.8), but a carrier-wide outage typically requires a fix from the provider. The incident underscores how reliant we are on stable DNS and network infrastructure, and it raises questions about remediation timelines and root cause from AT&T.
