The author discovered an interesting Monty Hall game simulation and decided to create their own version to compare outcomes when switching vs. not switching doors in the game. They built a side-by-side simulation to run both scenarios repeatedly, expecting the win percentages to converge to 66.7% when switching and 33.3% when not switching. The simulation allows users to start or stop the game, adjust the speed, and view cumulative statistics. The author also provides access to the code for the simulation.

The author reflects on the resurgence of 90s retro style, particularly the 88x31 web buttons, and decides to create a Game Boy button for their website footer. Lacking the artistic ability to design the button, they plan to use the Game Boy Color’s boot animation within a grey frame as the design. To extract the animation, they opt to use the SameBoy emulator, as their usual emulator (Rugby) doesn't support Game Boy Color yet. They describe the process of capturing

The content discusses event-driven architecture using the metaphor of making a "blog soup," which involves combining various elements to create a nutritious system. It emphasizes the importance of events, which record occurrences and support business observability, especially in Event Sourcing. Events can be processed either synchronously or asynchronously, with inline projections providing consistency but potentially slowing down event appends and increasing the risk of deadlocks. The author suggests that simple projections work better with inline processing, while more complex workflows benefit from asynchronous methods.
