In summer 2024, a company initiated a crucial migration of internal services to a private cloud to reduce spiraling public cloud costs, achieving savings of up to 80%. As the project leader, I learned an important lesson: "Design Twice." Initially, my plan was straightforward—ask clients to update their API hosts to new CNAMEs after the migration. However, the process was slow because not all clients prioritized the update. Eventually, one client proposed a simpler solution: redirecting traffic from

The article discusses the historical and evolving interest in enumerative geometry, which concerns counting solutions to geometric conditions. Initially popular among ancient Greeks, examples included determining how many circles can touch three given circles at one point each—an answer that took 1,800 years to prove. Over time, the complexity of counting problems increased, leading to advancements in the field. However, by the mid-20th century, interest diminished as mathematicians shifted focus to more abstract concepts, with only a brief revival in

The author is developing a proof of concept for a Redis RESP3-compatible key/value database based on FoundationDB, which has presented interesting challenges in distributed systems. Previously, they built a Graph DB using Roaring Bitmaps to represent relationships, allowing for efficient boolean operations on large sets of user IDs. However, with the need to accommodate millions of records and possibly more than 15 billion unique URIs in the AT Proto Ecosystem, the keyspace exceeded the limitations of uint32 values. They decided to
