问题 I'm trying to update a user document that looks like this: { _id:"xyzdon'tcare", username:"john", examTrials:Array[ { trialId:"x1", examId:"y", questions:Array[ {ques1 Object}, {ques2 object} ] }, { trialId:"x2", examId:"z", questions:Array[ {ques1 Object}, {ques2 object} ] }] } I tried the most straightforward way, findOne() then modify the document then save().The problem is, I faced race condition problems with the document versions when a new request arrived before the previous update

问题 I have an Android that uses firebase for authentication and MongoDb as a backend, I'm currently on the M0 cluster where the connection limit is 500. I use the Stitch API. When I use app from my device the number of connections increases from 4 to 8. I think initial 4 connections are by default so I don't mind that but I'm really concerned about such a jump in number of connections from a single device. PS. I tried having StitchAppClient and RemoteMongoClient in common class, so that there

问题 I have linked the project with ATLAS library, -llapack -lf77blas -lcblas -latlas -lgfortran , and it could compile successfully. But when I use the ldd command to view the dependency libraries, the output is as follows: ubuntu@ubuntu-desktop:~/Desktop/qt_output$ldd test_atlas linux-vdso.so.1 => (0x00007fffa99ff000) libopencv_core.so.2.4 => /home/ubuntu/Documents/3rdparty/lib/libopencv_core.so.2.4 (0x00007fe0577d7000) libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3

问题 So this is my first app and I am stuck and for almost a week I can't find a solution. I've created a lot of animations for different characters and found out that my game' memory usage is about 200 mb. Before I didn't worry about this because, as many beginners I thought that after I'll compress my png textures this size will decrease also. But that didn't happen. So I started to search what I can do about it and found out that changing the texture format from default RGBA8888 to RGBA4444 can

问题 I'm using texture atlas for handling my images. I didn't created the atlas by myself however I let Xcode to do this for me: My question is: How can I see this file or know its properties (I mean, sizes and weight)? What if and how can I know if the sizes exceed the maximum size of 4098 x 4098 pixel? 来源： https://stackoverflow.com/questions/33561727/how-check-the-spriteatlas-sizes-generated-by-xcode

问题 I have a new sandbox cluster on MongoDB Atlas that I am connecting to with mongoose on a Node.js server. This is the code I'm using to connect: const mongoDbUrl = `mongodb+srv://${username}:${password}@mydb-sandbox-12345.mongodb.net/testdb` mongoose.connect(mongoDbUrl) const connection = mongoose.connection connection.on('connected', () => { console.log('Connected to mongodb') }) In the Atlas dashboard I have a readWriteAnyDatabase user that I am authenticating with. Authentication works as

问题 I'm trying to install Scikit-Learn on a 64-bit Red Hat Enterprise 6.6 server on which I don't have root privileges. I've done a fresh installation of Python 2.7.9, Numpy 1.9.2, Scipy 0.15.1, and Scikit-Learn 0.16.1. The Atlas BLAS installation on the server is 3.8.4. I can install scikit-learn, but when I attempt to import it in Python, I get File "<pyinstall>/site-packages/scipy/parse/linalg/isolve/_iterative.so: undefined symbol: slamch_" Similarly, when I run >>> import scipy; scipy.test()

问题 What I've noticed when running project on iPhone 6+ simulator is that simulator don't pick up right images. Instead of @3x, @2x images are used. I tried reseting simulators content and settings, clean project and delete derived data from organizer and same thing still happens. When I look for the myatlas.atlasc folder inside the myapp.app (show package contents) at the path: /Users/username/Library/Developer/Xcode/DerivedData/appname-appspecificgeneratedstring/Build/Products/Debug

问题 I'm building numpy from source on CentOS 6.5 with no root access (python -V=2.7.6). I have the latest numpy source from git. I cannot for the life of me get numpy to acknowledge atlas libs.
