问题 I need a common rule for warnings in x64 mode. Which way is better? Consider the following lines of some code const int N = std::max_element(cont.begin(), cont.end()) - cont.begin(); or const int ARR_SIZE = 1024; char arr[ARR_SIZE]; //... const int N = std::max_element(arr, arr + ARR_SIZE) - arr; It is my usual code. I have no problems with x86. But if I run compiler in x64 mode I have some warnings: conversion from 'std::_Array_iterator<_Ty,_Size>::difference_type' to 'int', possible loss of

问题 My app has a thread that does some time consuming job for more than a minute and the app consumes around 6.8MB of memory. I receive a memory warning after sometime and then it gets killed. There is nothing that I can release, and I am using not even 7MB of memory...driving me crazy...any advice please? 回答1: Maybe your memory is super-fragmented? Even 7mb full of leaked data shouldn't kill your app. You ought to have at least 20mb to play with. Try rebooting the phone and see if that helps.

问题 I just read this post about why new-line warnings exist, but to be honest my team has people working on several different platforms and with several different editors (everyone uses what bests suites them), so the warning has become ubiquitous, and since its not really a warning worth taking care of it's become noise and makes finding serious warnings a hassle. Many times important warnings have gone unnoticed because, people got used to having a gazillion useless warnings pass by, so they

问题 In a Python module where I use matplotlib , I want to make sure it works also when I run the script on a remote machine via ssh . So I do: import matplotlib matplotlib.use('Agg') from matplotlib.backends.backend_pdf import PdfPages import matplotlib.mlab as mlab import matplotlib.pyplot as plt import numpy as np import pylab import scipy.stats import scipy.stats.mstats It works. Too bad that when I run it directly on a machine ( not a remote one !), it gives me the following warning: This

问题 Can anyone tell me about the below warning refers to in android eclipse. "Keybinding conflicts occurred.They may interfere with normal accelerator operation". Thanks for your time! 回答1: This means that a shortcut was set for two different actions. If you try to execute the concerning shortcut you will get a little box on the bottom right where you can choose which action you want to execute. So this isn't a serious problem for some actions this makes sense. 来源： https://stackoverflow.com
