lynzrand··on Petrova Task Force 2026 (Reimangining Project Hail Mary at 2026)
The description, from the authors:

> A contemporary reimagining of Andy Weir’s Project Hail Mary. The timeline and development of the Hail Mary, from Petrova line discovery through launch and beyond.

lynzrand··on The anatomy of a Godot API call
C# strikes the balance between speed and dynamic features IMHO. Especially for games that need mod support (which is not that uncommon at all), using C# allows for the modders to easily interface with existing code, while still getting near-native performance thanks to the type system and JIT. C++ code in such case would be too rigid to be modified and hard to interface wth.
lynzrand··on Is Rust stack-efficient yet?
You can access C#'s GC metrics through `System.GC.GetTotalAllocatedBytes` and similar APIs. Maybe you can make a benchmark and tracker for it yourself!
lynzrand··on Ask HN: Algorithms and data structures for humans and physical objects?
Wow, this insight really helps. Thanks for the pointers!

Maybe changing it into finding an archive file given its ID (not an auto-incrementing key, but something like its owner's national identification number) is better? They both belong to the category of creating a sorted dictionary structure in the physical world.
lynzrand··on Welcome to Waifu Labs v2: How Do AIs Create?
As a rough guess, I think it might be trained on the Danbooru archive dataset, since it's the largest anime picture dataset we can get today.

lynzrand··on China sends a drone (UAV) to provide temporary mobile network in disaster area
Maybe, but you need to send the balloon to that place and inflate it, then you need to control its altitude so people could get signal on the ground. It doesn't seem to be easy.

An UAV's advantage is that it can fly on its own and fly a long distance (Wing Loong's flight time is said to be 30 hours). Given enough drones they can deploy a continuous mobile network across a large area.

One good alternative I can think of is deploying small self-contained mesh networking devices, something like Project Owl, directly from air. These devices can form an emergency network for communicating urgent needs.

Translation:

> Hello villagers from Mihe Town,

> Communication has been cut off by the heavy rain. The emergency management department deployed a Wing Loong UAV above you in response of your emergency need, and it can restore mobile network for China Mobile. Due to limitation on the UAV's flight time, this mobile network can only last for 5 hours. Please report your status to your relatives as soon as possible. Wish you safe!
