The benchmark conducted by Jann Horn reveals that Linux performs unexpectedly slowly compared to OpenBSD, which is significantly faster. The test involved creating an extra thread while two existing threads created 256 sockets. The author had to modify the program for OpenBSD due to the limited precision of the time utility. While the results from Linux were disappointing, OpenBSD demonstrated superior performance. Although the systems tested were not identical, they were comparable. The author hints that the code contains clues related to performance, and expresses curiosity

In July 2013, Y Combinator's advice emphasized the importance of doing things that don't scale for startup founders. Many aspiring entrepreneurs mistakenly believe that startups grow organically once a product is launched. However, success often requires active efforts from founders to drive growth. A key example is Stripe, which is known for its aggressive user acquisition tactics. Instead of passively waiting for users to adopt their service, the Collision brothers would personally engage potential users by setting them up on the spot. This process reflects

NASA astronaut Nichole Ayers captured a rare phenomenon known as a gigantic jet on July 3, 2025, while aboard the International Space Station. This event is a type of Transient Luminous Event (TLE), specifically a powerful electrical discharge that extends from thunderstorm tops into the upper atmosphere. Gigantic jets typically form during turbulent conditions in thunderstorms and create an electrical bridge between the clouds (about 20 km up) and the atmosphere (around 100 km).

The post, part of a series on connection management challenges, focuses on the critical role of reverse proxies in load balancing requests among upstream servers. While round-robin load balancing works at a small scale, it becomes complex in larger systems due to varying request types, leading to potential server overloads and underutilization. For instance, different requests like image uploads versus profile lookups demand different resource allocations. The text also discusses the need for request stickiness to specific hosts, which round-robin cannot address
