Klement on Investing • 5 implied HN points • 17 Dec 25
💰 Finance Investing Risk Asset allocation Portfolio Equities Markets
  1. Over nearly a century U.S. small-cap stocks beat large caps on average, but that average hides very long stretches of underperformance that can last decades.
  2. Factors like value and size can stop working for longer than investors can stay invested, so multi-decade waits make them impractical for many investors.
  3. Academic evidence for factor outperformance can be sample-dependent and misleading, meaning results that look strong in one historical period may reverse in another.

What Year One of Building an AI Company Taught Me

The Incrementalist • 4 implied HN points • 01 Jan 26
💼 Business Leadership Product Startups AI Operations Strategy
  1. Speed and constant shipping don’t create clarity; clarity comes from restraint, simplifying the product, and tightening the loop so the product feels obvious not just impressive.
  2. You can’t outsource judgment — you earn it by sitting with ambiguity, watching what actually works in your specific context, and updating your beliefs based on results.
  3. The real product is judgment and reliable systems that handle messy, real work; build systems that remember, can be inspected and corrected, and manage exceptions over time.

Understanding Cryptocurrency's Ponzi-nomics [Finance Fridays]

Technology Made Simple • 99 implied HN points • 03 Dec 22
💰 Finance Financial risk Cryptocurrency Investing Market Analysis
  1. Some cryptocurrency firms were using tokens as collateral for loans, potentially allowing them to have infinite money, but this practice made the system very inter-connected and vulnerable to collapse.
  2. Using tokens as collateral is similar to companies using shares as collateral; if the value of the token or coin drops, the collateral becomes worthless, leading to the collapse of the ecosystem.
  3. The issue arises when multiple firms in the industry follow the same practice, creating a facade of liquidity, but in reality, the entire system is built on a risky foundation, vulnerable to collapses.

Prompt engineering is spaghetti code

Sunday Letters • 59 implied HN points • 08 Oct 23
🕹 Technology Optimization AI Software Programming Computing
  1. Prompt engineering is not a lasting software discipline; it may fade away as technology improves. It's a reaction to a lack of computing resources, trying to make every use of AI efficient.
  2. Using AI tools should be approached like programming: break tasks into smaller pieces to handle them better. This is more effective than creating complex prompts that are hard to manage.
  3. It's better to focus on making something work well before worrying about cost or optimization. Don't stress about minimizing resource use until the solution is working reliably.
