showing incorrect answer for total physical memory size in java -


यह कोड है 

  import java.lang.management.ManagementFactory; सार्वजनिक कक्षा मेमोरीज़ सिज {सार्वजनिक स्थिर शून्य मुख्य (स्ट्रिंग [] आर्ग्स) {com.sun.management.OperatingSystemMXBean mxbean = (com.sun.management.OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean (); System.out.println (mxbean.getTotalPhysicalMemorySize () + "बाइट्स");   
 उपरोक्त कोड मुझे  2147483647 बाइट्स  के रूप में आउटपुट मान देता है जो  1.99 जीबी  के बराबर है। लेकिन वास्तविक  स्थापित मेमोरी (रैम) 3.00 जीबी (2.30 जीबी प्रयोग करने योग्य)  है। मैं सही मान कैसे प्राप्त कर सकता हूँ i।, 2.30 जीबी कृपया मदद करें।   
 
 
 32 बीट प्रक्रिया को अधिकतम स्मृति में लेने की अनुमति केवल 2 जीबी है यदि आप 64 बिट जेवीएम का उपयोग करते हैं, तो आपको पूर्ण आकार दिखना चाहिए।

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

c++ - How to define methods in a base class that only work in derived classes? -

The title is slightly ambiguous, so I will say an example of what I want to achieve: Class ValuePtr {Public: Operator Canned void * () {return glm :: value_ptr (* this); // value ptr will not work on this class // (works only on glm type)}}; Square mat4x4: public glm :: mat4x4, public valuePtr {// ... but will work here}; Square Vec3: Public glm :: vec3, Public ValuePtr {// ... and here. } Is such a thing possible? glm :: value_ptr works only on glm type like glm :: mat4x4 , glm: : Vec3 , etc. The above seen method works if I implement it directly into derivative classes, but they should all be defined as operator construct * zero * in the same way. I should behave like a special behavior: define it in the general base class, whereas definition only works in derived classes. Thank you for the answer, I use this solution: template & lt; Class T & gt; Class ValuePtr: Public T {Public: Operator Constant * () {return glm :: value_ptr (* this); }}; Class ...
