    Stone Lantern V1.0 (MC 1.5.1/1.5.2)
    Mod Name: Stone Lantern Default ID: 184 Version: 1.0 MC Ver's: 1.2.5, 1.3.1, 1.3.2, 1.4.2, 1.4.4, 1.4.5, 1.4.6/1.4.7, 1.5.0, 1.5.1/1.5.2 LU: [13.04.04] This mod adds a craftable Stone Lantern to Minecraft. I made this mod so you can easily craft as many Lanterns as you need. Why this is needed in Minecraft: - Jack-O-Lanterns: I got sick of having to find Pumpkins. Then having to plant, wait for them to grow and harvest them. You can't even place Jack-O-Lanterns without a block under them first. Who wants to look at that all of the time anyway? - Redstone Lanterns: You literally have to go to Hell (The Nether) and back to craft them. And they have to be powered by a Redstone Torch or a Switch. Too much of a pain to craft, and not Renewable. I hope Mojang adds this to Minecraft in a future update. PS: Source Code is also included in the zip files. :-)

    spark

    spark

    A performance profiler for Minecraft clients, servers, and proxies

    spark is a performance profiling and diagnostic tool designed for Minecraft servers, clients, and proxy software. It helps developers and server administrators analyze performance issues such as lag, high CPU usage, and memory bottlenecks. The plugin collects statistical information about the server’s execution and generates detailed profiling data that can be used to identify inefficient code or problematic plugins. spark includes tools for CPU profiling, memory inspection, and monitoring server health metrics over time. The profiling data is typically visualized through an online viewer that displays call graphs and flame graphs to help users interpret performance results. Because it is lightweight and designed to run in production environments, administrators can safely use it on live servers to diagnose performance issues without significant overhead.
