Someone i know has a memory issue with java sound.


Hello everyone,  

Someone I know asked me about a problem he has with a program he is writing. I know nothing about his code, but he is writing a keyboard program, with the midi synthesizer in the sound api. what I do know is that he is using note on when a key is depressed, and note off when it is released.  

I don't know what made him do it, but he decided to watch task manager as he tested this program (in eclipse if it matters), and the more keys he pressed the higher the memory usage of the program went, and didn't decrease.  

I have no explanation for him, I recommended that he register here and ask for himself, but as he hasn't done it, I suspect he won't.



Does anyone know something I can tell him?
Does he ever get a Heap Space exception? Does he ever even fill at least have of the Heap Space? If not, it may just be that the JVM hasn't felt that a GC run has been necessary yet. Also, even if it has, Java only reserves from the system the min heap space, then, as that is surpassed will periodically reserve more until the Maximum Heap Space has been reached. ***But*** the JVM *never* releases that memory back to the System. So, even though the memory usage of the JVM *seems* to go up and up and up, from the System view, that doesn't mean there is any kind of memory problem. Find a profiler and monitor the actual Heap Space, not the system memory usage of the JVM.

i have difficulty understanding why (since ultimately, rts should be dependent on keyboard press rather than frame rate).

builder experiments are structured around a drawing loop and event cycle that is driven by the screen refresh rate. so the keyboard is checked once … its to do with the jit optimisation, the same is true if you insert conditional debug statement in the code, matlab needs to prepare to stop execution. a person's memory is actually made of different parts and each part has different possible causes for memory loss. in general, memory problems can occur from alcohol abuse, mood disorders, psychosis, stress and anxiety, psychological trauma, head injuries and dementia. however, at your age, you may simply have too much to think about and this may cause problems with "working memory". see more... I have a huge problem with reproducing kanji from memory, but I can recognize them and know their readings when I am looking at my textbook or trying to read something basic. What is the best way to remedy this? I'm thinking of taking every kanji I know and writing them each ten or twenty times until the stroke orders and readings are burned into my mind. I can't think of any other way. there is no need for a program to do that. 

here are some simple steps which you can follow:

1.right click on your taskbar and choose start task manager.

2.once task manager is opened go to "processes" tab. 

3.when at the processes tab search for .exe file. (maybe in your case it will look like loop.exe or something) 

4.once you have found it. just right-click on it and hover over to "set priority" option. 

5.here are several options. the default one will be "normal" so just set that to "below normal" or "low". (i would prefer setting it to "below normal" so that it does not act strangely) 

6.it's done now restart your program and check the amount of ram it is using.

i hope this helps you. if not leave a reply and i will figure out another solution. glad to help.:) Hi


Normal behavior is that when you are using a tool, and then press and hold a shortcut key while you use another tool, Photoshop will jump back to the first tool when you release the key.


 


I watched your video, and this is not what is happening to you — you are releasing the keys. Two thoughts for trouble-shooting purposes:


* Can you try another keyboard?
* Can you try with a mouse?
* Have you tried resetting Preferences? This is different from uninstalling and reinstalling. Go to Prefs > General and click Reset Preferences on Quit.


Maybe another volunteer will have other ideas if these don't work.


 


~ Jane interesting.... hmm, it looks that the ./bin/elasticsearch script is requiring the keystore password input from stdin

if you look at the actual script that starts ./bin/elasticsearch you can see why.

from the script

# get keystore password before setting java options to avoid

# conflicting gc con… different people have different comfort levels. it sounds like he is easily put off by your praising of your friend. some people are hypersensitive about certain issues and i think you found his off button. too bad he couldn't have a conversation about it and just blocked you because that seems wrong. Dear Sir,   

I has change the printer cartridge. After changing the printer cartridge above mentation comming. When I am making printer power on the (10.10.00 supply memory error) display. Please tell me how to solve this problem. Best regards,
