We keep increasing memory_limit in php.ini, but it is now up over 1000 megs. What is a normal memory_limit value? What are the usual suspects in php/Ze...
I am having problems with memory addressing in MIPS. It says that the addressing is word aligned... in the text below I don't understand why it's looking at the 2 least significant bits of the address? why? can someone give me an example to clarify/illustrate the point made here... so is it saying that a valid halfword address are all wh...
I wish to manipulate data on a very low level. Therefore I've a function that receives a virtual memory address as an integer and "does stuff" with this memory address. I interfaced this function from C, so it has the type (CUInt -> a). The memory i want to link is a Word8 in a File. Sadly i have no idea how to access the pointer value t...
I 'd like to prepare my PNGs for the best optimization, so I can get the best image quality (lossless if possible) and the smallest size. From what I understand, I should use: PNG, 72 dpi, RGB, but what else? Here is what we find in the iPhone HIG: Note:*The standard bit depth for icons and images is 24 bits (8 bits each for red, gree...
I am using Visual C# Express 2008 and I have an application that starts up on a form, but uses a thread with a delegated display function to take care of essentially all the processing. That way my form doesn't lock up while tasks are being processed. Semi-recently, after going through a repeated process a number of times (the program p...

I have a web scraping script that gets new data once every minute, but over the course of a couple of days, the script ends up using 200mb or more of memory, and I found out it's because mechanize is keeping an infinite browser history for the .back() function to use. I have looked in the docstrings, and I found the clear_history() func...
Hi, I'm using Oracle 9.2x to do some xmltype data manipulation. The table as simple as tabls(xml sys.xmltype), with like 10000 rows stored. Now I use a cursor to loop every row, then doing like table.xml.extract('//.../text()','...').getStringVal(); I notice the oracle instance and the uga/pga keep allocating memory per execution of...
Hi I need ideas on how to write a C program that reserve a specified amount of MB RAM until a key [ex. the any key] is pressed on a Linux 2.6 32 bit system. * /.eat_ram.out 200 # If free -m is execute at this time, it should report 200 MB more in the used section, than before running the program. [Any key is pressed] # Now all the r...
I am always confused about static variables, and the way memory allocation happens for them. For example: int a = 1; const int b = 2; static const int c = 3; int foo(int &arg){ arg++; return arg; } How is the memory allocated for a,b and c? What is the difference (in terms of memory) if I call foo(a), foo(b) and foo(c)? ...

Hello, I am developing a library in C++ where users/programmer will extend a class BaseClass that has a method initArray. This method should be implemented by the user/programmer and it should normally initialize all elements of the array m_arr. Here is a snipplet, modified to this example: class BaseClass { public: BaseCla...
Hi! I'm using ASANT to run a xml file which points to a NARS.jar file. I'm getting "java.lang.OutOfMemoryError: Java heap space" and i'm researching around this. So i have found that i need to set "-XX:+HeapDumpOnOutOfMemoryError", to create a dump file to analyze. I edited ASANT.bat and added the "-XX:+HeapDumpOnOutOfMemoryError" to ...
I'm making a little benchmark class to display page load time and memory usage. Load time is already working, but when I display the memory usage, it doesn't change Example: $conns = array(); ob_start(); benchmark::start(); $conns[] = mysql_connect('localhost', 'root', ''); benchmark::stop(); ob_flush(); uses the same memory as $conn...
IBM JRE 5.0 on Windows, when given -Xmx1536m on a laptop with 2GB memory, refuses to start up: error message below. With -Xmx1000m it does start. Also, it starts fine with -Xmx1536m on other servers and even laptops, so I think that there is something more than just inadequate memory. Also, when started from within Eclipse (albeit, u...
Hi, I have a strange behaviour. I am using a rather heavy page (4000 nodes) meant to display a dispatch system for delivery operations. Every 30 sec. I am refreshing with jquery, the list of operations (3000 nodes over 4000). It works perfectly well, but... each time, the memory of both firefox and chrome is increasing by 3 to 6ko. Of c...
hi. I'm running JBoss as a windows service, but i can't seem to find where i can configure the JAVA_OPTS to make it work properly. I need to set the Xms and the Xmx.
