i using libgdx generate 3d mesh in code. right attempting generate flat plane many vertices in middle test things out, received exception in thread "lwjgl application" java.nio.bufferoverflowexception when called mesh.setindices(indices); variable indices short array. i not having trouble if have less 180-150 indices. wasn't able figure out exact number trail , error, exception thrown if have more 180 indices. here code creating mesh: firstly how generate vertices (i don't think problem, ill put them in anyways) *note vertex attributes (vertexattribute.position(), vertexattribute.normal(), vertexattribute.colorunpacked()) private float[] generatevertices(int width, int height) { int index = 0; float vertices[] = new float[width*height*10]; for(int = 0; < width; ++) { for(int j = 0; j < height; j++) { //vertex coordinates vertices[index] = i; vertices[index+1] = 0; vertices[index+

how convert binary field of type 4 type 0 using shell script ? i thought running simple script this db.places.find({}).foreach(function(data) { // how data ? print(data.id); // db.places.update(....) }); but couldn't figure out how binary data can construct new binary. object.keys() shows there 2 fields: type , len you can not force type. don't quite understand why want this, can rewrite document force new type: db.places.insert( { id: new bindata( 0x04, "sevmte8=" ) } ); db.places.find(); { "_id" : objectid("5204c4f252d346a74dd17755"), "id" : bindata(4,"sevmte8=") } so script, can this: db.places.find({}).foreach(function(data) { bindata = data.id.base64(); db.places.update( { _id: data._id }, { $set: { id : new bindata(0, bindata) } } ); });

i have few machine learning models have trained (size in 300mb - 4 gb). want query them using rest api. build apis in flask require these models in memory. google app engine suitable it? or should use compute engine instead? it's unsuited appengine because of reasons like: appengine not have instances ram (unless use flexible same gce option). even if did, instance can go away requires reload data memory (thou on memcached) time restrictions on frontend instances make unlikely can time load data memory, less being able analyze data. backend type of instance it, harder doing regular vm. good luck loading libraries need, none should write file storage, temp file. thus compute engine correct place.
