The content explains the concepts of shared and exclusive locks in the context of database transactions. 1. **Shared Locks (FOR SHARE)**: When a transaction reads a row using a shared lock, it prevents other transactions from updating or deleting that row until the current transaction is complete. However, multiple transactions can still read the row simultaneously. 2. **Exclusive Locks (FOR UPDATE)**: When a transaction intends to update a row, it acquires an exclusive lock, preventing any other transaction from reading or

In a scenario where you and a friend in different cities try to clap at the same time using your watches, you may not clap at the exact same instant due to slight discrepancies in your watches. This problem is mirrored in large computer systems, such as those used by FAANG companies, where numerous computers worldwide have their own internal clocks that are not perfectly synchronized. When two events occur on different computers, their timestamps may not accurately reflect the order in which they happened. While protocols like the Network Time Protocol

The page discusses the concentration of user data on the Fediverse and Atmosphere using the Herfindahl–Hirschman Index (HHI), a metric from economics that assesses market competition. HHI values range from close to zero (indicating a competitive market with many evenly distributed servers) to close to 10,000 (indicating a monopoly). Values below 100 suggest a highly competitive market, below 1500 indicates an unconcentrated market, and above 2500 shows high

The author shares a nostalgic and humorous reflection on a Git commit message from 2013 by developer Dan Carley, which reads more like a personal diary. The commit's header states, "Convert template to US-ASCII to fix error," but the body details Dan's thought process while addressing a non-ASCII character bug in an US-ASCII environment. He narrates how he discovered the bug through tests that failed under specific conditions and methodically reproduced the error by stripping the `.with_content(//

The author explains the purpose and function of the CSS property `will-change`, which serves as a performance optimization hint to the browser. It signals that certain properties will be animated, prompting the browser to prepare for those changes. This may involve promoting the element to its own GPU compositing layer or pre-allocating memory, although the browser has the discretion to ignore the hint if it determines the potential performance gain is minimal. The browser's rendering process consists of three steps: calculating layout dimensions (CPU work
