Driven by a desire to learn networking and improve his Common Lisp skills, the author embarked on creating a multiplayer shooter game. He chose the relatively low-level Hunchentoot web server, using WebSockets for communication and opted for a client-server architecture over peer-to-peer for simplicity. Development involved tackling challenges like client-side prediction, interpolation, and hit detection while managing the complexities of game state synchronization. The project, though rudimentary graphically, provided valuable experience in game networking and solidified his appreciation for Lisp's flexibility and the power of its ecosystem. The final product is functional, allowing multiple players to connect, move, and shoot each other in a simple 2D arena.

HN users generally enjoyed the "Find the Odd Disk" color puzzle, praising its elegant simplicity and clever design. Several pointed out the effectiveness of using just noticeable differences (JNDs) in color to create a challenging but solvable puzzle. Some discussed optimal strategies, with one suggesting binary search as the most efficient approach. A few users shared their completion times, and others expressed their satisfaction in solving it. There was some light debate over whether it was truly JND or slightly larger differences, but the overall consensus was positive, with many appreciating the break from more complex or stressful topics typically discussed on HN.
The Hacker News post "Find the Odd Disk" with ID 43745868, referring to the article about a color perception puzzle, has a modest number of comments, generating a brief discussion around the puzzle and related topics.
Several commenters discuss strategies for solving the puzzle. One commenter suggests a systematic approach, recommending starting by comparing the top-left disk to its neighbors and then systematically comparing adjacent disks, noting that the difference might be subtle. Another suggests a more visual approach, stating that squinting can help exaggerate the color difference. A third commenter explains their method, mentioning that they focused on the center of each disc, noticing a slight but consistent difference in the "odd" disk's color.
Beyond solution strategies, one commenter goes deeper into the science of color perception, mentioning the concept of "just noticeable difference" (JND) and how it plays a role in the difficulty of the puzzle. They discuss how the puzzle leverages subtle differences in color that are close to the JND threshold, making the odd disk challenging to identify.
A couple of commenters share their personal experiences with the puzzle. One admits to struggling with the puzzle, despite generally having good color vision. Another mentions finding the mobile version easier due to the increased color saturation on their screen.
Finally, one commenter draws a parallel between the puzzle and real-world applications, suggesting it's a good analogy for the challenges faced in tasks like identifying anomalies in large datasets. They point out that the subtle difference in the disk colors mirrors the subtle differences in data that can indicate important, yet easily overlooked, patterns or problems.
In summary, the comments on the Hacker News post primarily revolve around strategies for solving the color puzzle, discussions of color perception principles, and reflections on personal experiences with the puzzle, with a touch of relating the puzzle to real-world problem-solving. The conversation remains focused and relevant to the original post, offering different perspectives without veering into unrelated tangents.
