cross-platform

问题 I would like to monitor the following system information in Java: Current CPU usage** (percent) Available memory* (free/total) Available disk space (free/total) *Note that I mean overall memory available to the whole system, not just the JVM. I'm looking for a cross-platform solution (Linux, Mac, and Windows) that doesn't rely on my own code calling external programs or using JNI. Although these are viable options, I would prefer not to maintain OS-specific code myself if someone already has

问题 is it Available ? or should I choose my own algorithm to encrypt data and upload it to the S3-bucket? I'm having a requirement to create an application in multiplatform(android/C#/ios) in which we have to encrypt data and Store it to the server side . . . I've tried this library to encrypt data, but in iOS side, I'm having different results than others . . . 回答1: I uploaded a video on aws s3 bucket with client side encryption using below code. We need the AES256 key and md5 key when going to

问题 I am trying to get the Views in my xamarin-forms + mvvmcross project to load correctly with no luck. Project structure breakdown: Project: Shared.Core - 100% cross platform code, view models, models, etc.. Project: Shared.Mobile - Xamarin-forms views Project: iOS - uses shared views Project: Android - uses shared views Project: UWP - uses shared views Project: WPF - uses WPF native views I have a working WPF project using mvvmcross and am trying to get the mobile going starting with iOS. The

问题 On a previous question the pathinfo and fnmatch functions were benchmarked and the answers all came out opposite to my benchmark results. You can read the different results with the benchmark code here: pathinfo vs fnmatch I couldn't work it out until I ran the same code on a machine running vista. The results then matched the other users. My main machine is a mac. So, my questions are: Why do we get these two different results? Could this apply to other functions? 回答1: Why do we get these

问题 I'd like to know if there are other compilers than gcc and clang that provide something like an -march=native option, and if so, what that option is. I already understand from another question (Automatically building for best available platform in visual c++ (equivalent to gcc's -march=native)) that Microsoft's compilers do not have that option (unless it's implied in the option that activates the SSE2 instruction set, up to and excluding AVX and higher at least). The use case is simple:

问题 Does anyone know how I would print the contents of a scrolled composite? Whenver I print onto a GC it will only copy the currently viewable area of the scrolled composite. What I want is to be able to copy the entire contents of the scrolled composite. For instance, the code below makes a huge button, inside of a little window. Whenver I print the gc below, it only will output the small viewable area of the scrolled composite. Is it possible to print everything in the scrolled composite?

问题 I use memtables to wire enumerated type with comboboxes using LiveBinding. However I have a lot of them and they way I am doing is way too bad (copy/paste) For example, I have the following enumeration: TEnumResourceType = (trtApp, trtTab, trtSection, trtField, trtCommand, trtOther); and for that I created a function to give the string equivalent: function EnumResourceTypeToStr(AEnum: TNaharEnumResourceType): string; begin case AEnum of trtApp : result := 'Aplicação'; trtTab : result :=

问题 Obviously you can't really run Mac or Linux apps on Windows, but can you compile binaries for those platforms using MSVC++ for example (plugging in additional compilers and tools obviously)? For a serious build system, you don't want one build server per platform so having an automated build server which compiles for all target platforms seems quite a reasonable aim. 回答1: Crosstool-NG seems like your best option for Linux apps; they show that as one of the standard configurations. I do not

问题 A software library that I am working with writes a lot of debug output to std::cerr , but redirects that output to a null stream if I tell it to be quiet. This is a simplified main.cpp that shows how the code tries to achieve this: #include <iostream> #include <fstream> #include <cassert> // The stream that debug output is sent to. By default // this points to std::cerr. std::ostream* debugStream(&std::cerr); // Throughout the library's codebase this function is called // to get the stream
