WHAT IS A VECTOR DATABASE?

Many AI applications that involve large language models or generative AI rely on vector embeddings, a type of data representation that carries within it semantic information that’s critical for the AI to gain understanding and maintain a long-term memory they can draw upon when executing complex tasks. Vector databases offer optimized storage and querying capabilities for embeddings. They have the capabilities of a traditional database that are absent in standalone vector indexes and the specialization of dealing with vector embeddings, which traditional scalar-based databases lack.

SHOULD YOU OPTIMIZE FOR ALL-CASH COMPENSATION?

Tech companies often allow employees to choose their stock and cash ratio, especially if the company stock had a drastic fall. However, the choice of how much stock to get can be complicated - on one hand, employees have access to “insider information” such as usage statistics and business dashboards. On the other hand, even with this information, employees can’t control how the stock will perform since it depends on a number of factors, such as market expectation. This blog shows numerical experiments on what will happen depending on your stock/cash ratio if you were a Shopify employee.

THE SURPRISING POWER OF DOCUMENTATION

Documentation can be boring to write, but its long-term value cannot be understated. Each hour invested into documentation at a company can save up to a hundred productivity hours as a result across the company. Building a documentation-first culture is extremely important for a team to scale well and for developers to stay productive as a codebase gets larger and larger. However, documentation is not a silver bullet or a substitute to human interaction, which has nuances that cannot be transferred through the written word.

THE MYTH OF THE AI INFRASTRUCTURE PHASE

Can LLM infrastructure be built before LLM applications? The phrase “sell shovels in a gold rush” has led to a host of infrastructure for LLMs startups in the wake of the LLM boom. However, knowing the correct APIs and use cases for LLM infrastructure before real LLM-enabled applications are deployed for a long time is difficult. It may not be the time yet for AI infrastructure companies as actual AI applications need time to grow first so that actual problems can be discovered.

MENTAL LIQUIDITY

Mental liquidity is the ability to quickly abandon previous beliefs when the world changes or when you come across new information. However, mental liquidity is rare and can be hard to change as you get older. Morgan Housel, the author of Psychology of Money, lays out some anecdotes about how Albert Einstein himself even had a problem with mental liquidity. It’s important to be careful about what beliefs you let become a part of your identity and how most fields have theories, ideas, and hunches, but not laws - things that are unimpeachable and cannot ever change.
