vismit2000··on When a Crystal Ball Isn't Enough to Make You Rich (2024)
This research describes an experiment called the "Crystal Ball Challenge," where participants attempted to predict market movements using advance access to the Wall Street Journal front page. This research evaluates whether having future news leads to successful trading, particularly by examining the importance of trade-sizing in investment outcomes. The findings indicate that while experienced traders performed significantly better, often due to their sensible risk management, less experienced participants frequently failed to profit despite their informational advantage. Ultimately, the source concludes that simply possessing future information is insufficient for financial success without a disciplined approach to investment sizing.

vismit2000··on Dice and Queues
Little's law comes up in the beautiful book 'Programming Pearls' by Jon Bentley in 'Back of the Envelope' calculations:

- `Little’s Law`: The average number of objects in a queue is the product of the entry rate and the average holding time - Response-time formula for a multi-user system: - Assume n users of average think time z are connected to an arbitrary system with response time r. - Each user cycles between thinking and waiting-for-response, so the total number of jobs in the meta-system (consisting of users and the computer system) is fixed at n. - If you cut the path from the system's output to the users, you see a meta-system with average load n, average response time z + r, and throughput x (measured in jobs per time unit). - Little’s Law says n = x × (z + r), and solving for r gives r = n/x – z.

vismit2000··on How Kerala got rich
At the same time, also check out: How serious is Kerala’s drug crisis? (Data Point) - https://youtu.be/CLkRAmkgEM4

Kerala is in the grip of a rapidly growing drug crisis. The state’s High Court issued a stark warning about the ‘poisonous fangs of the drug mafia’. And the State Assembly even paused regular business to debate the issue.

Kerala now leads the country in drug-related cases, far ahead of states like Punjab and Maharashtra. The numbers are also far too high to be explained by good policing alone.
