VisualVM mentions (21)

• 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

• Ask HN: Would doing a coding bootcamp be a horrible idea?

  Don't do bootcamp. Start with something like https://freecodecamp.org and take a few lessons. Try to build something from that and see how motivated you are. If you see some progress and this thing still excites you, then may be find an engineer (a friend/co worker etc) who can guide you a bit as you continue to build something. Start small and stay away from bootcamps (my 2 cents). - Source: Hacker News / 5 months ago

• What's wrong with my resume? Former non-tech background designer and Current CS graduate student looking for first SDE/SWE internship, really, no good news at all but only rejections, please advice!

  Was thinking to put certificates, but those are what I earned from platform such as freeCodeCamp.org's backend api development, not sure if it's good to list in resume or not. Source: 9 months ago
