• I've figured out what 13 of the 16 enemy flags mean in Ultima V. Help me figure out the last three.

  I've got no experience with reverse-engineering executables, but I got a bunch of code-like stuff showing up when I fed ULTIMA.EXE to Ghidra and told it to analyze it with all the flags set. Source: about 1 year ago

• Modding SH2

  The whole game is written in C++ (game logic intertwined with graphics). Ghidra can help you deconstruct the game binaries, but you need to put in a GREAT great effort to even get a starting point. Cheat Engine has been successful for some purposes, including an AI enabling utility for multiplayer (use with great care!). Source: about 1 year ago

• You have probably heard of Temu right?

  What I think you’re talking about is reverse engineering. It’s basically taking a program and analysing the compiled code to attempt to find out how it works. It’s a fairly expansive topic, and fairly tricky to do but look at anything to do with Ghidra to get started. Source: about 1 year ago

• Asking for clarification ... How is learning C beneficial for becoming a Cyber security expert

  Oh also just as an aside Ghidra is a really cool free tool developed by the NSA which can reverse engineer software by looking at its executable and recreating the C code from the instructions and static data within. It's another way to get familiarized with the relationship between C code and the instructions it compiles to. Source: about 1 year ago

• Super Smash Bros. Melee HD Port Will "Never Happen," According to Former Nintendo Employees

  There exist decompilers and other tools for helping make sense of assembly and that can automate some of the conversion back to higher level languages. In my brief involvement with Slippi I used Ghidra - a tool developed by the NSA, to do some of that kind of work, which I found a little amusing. Source: about 1 year ago

• Can java collection be fixed?

  If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: about 1 year ago

• Items won't drop when either mined or dropped from inventory and new chunks won't load.

  Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: about 1 year ago

• Top metrics for Elasticsearch monitoring with Prometheus

  The Java VisualVM project is an advanced dashboard for Memory and CPU monitoring. It features advanced resource visualization, as well as process and thread utilization. - Source: dev.to / about 1 year ago

• Anybody know what causes this? Entities simply going idle, can't eat, fps is still high, can break blocks etc . I have a gtx 1660 ryzen 2600 and 16gb ram. So my pc isn't bad. I allocated 8gb of ram. Doesn't happen all the time . Happening on my modpack with 200 mods

  This sounds like a server thread freeze/deadlock/crash or something. I think I would start debugging this using a tool like VisualVM; attach it to the game, wait for the hang, take a thread dump, and check what the server thread is up to. Source: about 1 year ago

• Why use javafx

  Just wanted to chip in to say that /u/UtilFunction is correct. The proper way to measure memory consumption of any Java application independent of which garbage collector is used is to perform a heap dump (which automatically forces a complete garbage collection). I like to use VisualVM for that. Source: about 1 year ago
