i using conditional compile in java using newest android studio newest gradle. so did little test using static final boolean compilethiscode = false; if (compilethiscode) { callalargeclass(); } and created apk with static final boolean compilethiscode = true; i have expected apks of different sizes since callalargeclass large class but apks compilethiscode = true , compilethiscode = false have same size could please me understand why if java doing conditional compile ? this influence runtime memory consumption. apk size depends on libraries , resources (res folder). "hello world" in project multiple big 3d party libraries can hit 65k limit . you can exclude unused dependences proguard config.

(probably not relevant you, maybe others: careful, dd version offers "special"...

i have training set of 614 images have been shuffled. want read images in order in batches of 5. because labels arranged in same order, shuffling of images when being read batch result in incorrect labelling. these functions read , add images batch: # add files queue batch: def add_to_batch(image): print('adding batch') image_batch = tf.train.batch([image],batch_size=5,num_threads=1,capacity=614) # add summary tf.image_summary('images',image_batch,max_images=30) return image_batch # read files in queue , process: def get_batch(): # create filename queue of images read filenames = [('/media/jessica/jessica/tensorflow/streetview/training/original/train_%d.png' % i) in range(1,614)] filename_queue = tf.train.string_input_producer(filenames,shuffle=false,capacity=614) reader = tf.wholefilereader() key, value = reader.read(filename_queue) # read , process image # image 500 x 275: my_image = tf.image....

due unpredictable of racing situation of multiple symmetric threads, use uncertainty build uniform random generator? for example, codes http://www.cplusplus.com/reference/mutex/call_once/ , call twice generate random integer in [0,99]. #include <iostream> // std::cout #include <thread> // std::thread, std::this_thread::sleep_for #include <chrono> // std::chrono::milliseconds #include <mutex> // std::call_once, std::once_flag int winner; void set_winner (int x) { winner = x; } std::once_flag winner_flag; void wait_1000ms (int id) { // count 1000, waiting 1ms between increments: (int i=0; i<1000; ++i) std::this_thread::sleep_for(std::chrono::milliseconds(1)); // claim winner (only first such call executed): std::call_once (winner_flag,set_winner,id); } int main () { std::thread threads[10]; // spawn 10 threads: (int i=0; i<10; ++i) threads[i] = std::thread(wait_1000ms,i+1); std::cout << "w...
