I've been using mongo on my mac os x 10.8 and suddenly yesterday at my logs appeared this warning (and when starting shell it's present too) - WARNING: soft rlimits too low. Number of files is 256, should be at least 1000 Who could explain, what does it mean? And should I increase number of rlimits somehow? 回答1:

问题 The following problem occurs on a machine running Ubuntu 10.04 with the 2.6.32-22-generic kernel: Setting a limit for the Resident Set Size (RSS) of a process does not seem to have any effect. I currently set the limit in Python with the following code: import resource # (100, 100) is the (soft, hard) limit. ~100kb. resource.setrlimit(resource.RLIMIT_RSS, (100, 100)) memory_sink = ['a']*10000000 # this should fail The list, memory_sink, succeeds every time. When I check RSS usage with top, I

问题 What is the maximum memory limits per application for Android 2.2? 回答1: It depends on the particular device, usually ranges between 16 and 48 MB. 回答2: The lower limit for a low density / small screen, and medium density / normal screen device is 16 MB. The lower limit for a high density / normal screen device is 24 MB. Individual device manufactures can and do raise this limit for their device, depending on how much RAM the device has (and how many megapixels the camera is etc), but if you

问题 I need to produce large and big (very) matrices (Markov chains) for scientific purposes. I perform calculus that I put in a list of 20301 elements (=one row of my matrix). I need all those data in memory to proceed next Markov step but i can store them elsewhere (eg file) if needed even if it will slow my Markov chain walk-through. My computer (scientific lab): Bi-xenon 6 cores/12threads each, 12GB memory, OS: win64 Traceback (most recent call last): File "my_file.py", line 247, in <module>

问题 Given the code segment as follow, I just want to know why the maximum value of long double is smaller in 64bit than that in 32bit? why 64-bit version cannot expand as much digits as in 32-bit version to fill the "40" precision output? it seems that the values of LDBL_MIN and LDBL_MAX are equal, is that a bug? I have looked into the float.h files in my machine but cannot find the explicit definition of these macro constants. Testing Code (Platform = Win7-64bit) #include <cfloat> #include

问题 Is this guaranteed to be always true: std::numeric_limits<int>::max() == INT_MAX What does C++ standard say about it? I could not find any reference in the standard that would explicitly state this, but I keep reading that those should be equivalent. What about C99 types that are not in C++98 standard for compilers that implement both C99 (at least long long part) and C++98? I am not sure whether there is any guarantee that this always holds true: std::numeric_limits<unsigned long long>::max(

问题 I need to create multiple functions that will check if an input is valid or not. Here are some of my codes: bool IsValidRange(signed char s) { bool isValid = true; if (!((s>=SCHAR_MIN)&&(s<=SCHAR_MAX))) { isValid = false; } return isValid; } bool IsValidRange(int s) { bool isValid = true; if (!((s>=INT_MIN)&&(s<=INT_MAX))) { isValid = false; } return isValid; } I'm using the header limits.h for this. Am I doing this the right way? Please take note that I'm just a beginner. I hope you all will

问题 I'm trying to geolocate these 27 points at the same time, in the same row. But the process returns only the first 10 points, even if in the preview they are all 27 correctly geolocated. Why? Is there a particular limit to the number of points I can locate? <Point><coordinates>7.680237,45.064504,0.0</coordinates></Point> <Point><coordinates>7.681675,45.061957,0.0</coordinates></Point> <Point><coordinates>7.685044,45.060768,0.0</coordinates></Point> <Point><coordinates>7.686482,45.06029,0.0<

问题 I wrote a code that pick all the pixels with a specific color from an image and set them in a blank image. But at a certain amount of pixels imagesetpixel() stops. Can someone tell me why? <?php if(isset($_POST["submit"])){ header("Content-Type: image/png"); $img = imagecreate(200, 100); imagecolorallocate($img, 0, 0, 0); $im = imagecreatefrompng("img.png"); $x = imagesx($im); $y = imagesy($im); for($i=0; $i<$x; $i++){ for($j=0; $j<$y; $j++){ $rgb = imagecolorsforindex($im, imagecolorat($im,
