Links of the week
Feature Stores for MLOps Dummies
“For a basic understanding, it can be said that feature stores are like data warehouses for data science. Their primary goal is to enable data scientists to short-circuit the time it takes to go from data ingestion to ML model training.”
A Practical Guide to Capturing Production Traffic with eBPF
“eBPF allows you to add multiple filtering layers and it captures traffic directly from the kernel, significantly reducing the volume of output to only relevant data and ensuring you can handle the high throughput of your application traffic.“
The Lazy Way to Solve Differential Equations
“A lot of the techniques, specially those for equations with analytic coefficients, sometimes felt a bit mechanical. In fact, it almost always goes like this: Get your equation, Taylor expand everything, collect terms by indices and then solve the recurrence relations to find Taylor series for the solution.”
A Machine Learning Approach to Constructing an Inflation-Themed Equity Portfolio
“To form the Model Equity Portfolio, we hold 10% of the stocks with the highest predicted returns using the fitted model. Our starting universe of stocks is ~800 of the most liquid large cap stocks in the U.S., so this leaves us with a portfolio of ~80 stocks, which we believe to be fairly standard for a thematic equity portfolio“
Java Garbage Collection Distilled
“Documentation describing garbage collection feels like man pages for an aircraft. Every knob and dial is detailed and explained but nowhere can you find a guide on how to fly. This article will attempt to explain the tradeoffs when choosing and tuning garbage collection algorithms for a particular workload.“
Postgres Indexing: When Does BRIN Win?
“Because each page holds multiple rows, we can state that a given column in that page has a minimum and maximum value in that page. When searching for a particular value, the whole page can be skipped, if the value is not within the min/max of the page. This is the core magic of BRIN.“
