Uber faced challenges with its massive HDFS (Hadoop Distributed File System) deployment, which was lowering the efficiency of its clusters. To fix this, its team modified settings to increase data transfer rates and parallelism. They also improved its HDFS Balancer algorithm to prioritize data movement to the least utilized nodes and use percentiles instead of fixed thresholds for better target selection. This led to much better cluster utilization and efficiency.
Use of the “any” type is discouraged because it disables TypeScript's safety features, making code prone to errors and harder to maintain. However, there are some cases where using “any” is the right solution. It should be used in arguments when defining generic functions that should work with any function type. "any" can also be used with type assertions to work around TypeScript's limitations to accurately model functions that return different types based on input.

Startups often neglect internal documentation. This can lead to lost knowledge and worse efficiency during crises. The problem worsens as companies grow. To fix this problem, startups need to change their documentation culture. Leaders should set the standard and documentation should be expected in role profiles. Docs should be properly organized and owned by people or teams.
Apple Pay (and other digital wallets) use DPANs (Device Primary Account Numbers) instead of actual credit card numbers (FPAN) to protect customer information and reduce cross-merchant tracking. While DPANs change for different merchants, they remain the same for subsequent transactions with the same merchant. Apple Pay technically doesn't completely prevent individual stores from tracking your purchase history. It doesn't hide personal information, and merchants can still collect details like names, addresses, and product information for order fulfillment.
