问题 I have a program that is being symlinked to multiple directories e.g. /main/foo.pl /run1/foo.pl -> /main/foo.pl /run2/foo.pl -> /main/foo.pl /run3/foo.pl -> /main/foo.pl /run4/foo.pl -> /main/foo.pl They're being run as cron jobs, hence I have the following entries in the crontab: */2 * * * * /run1/foo.pl */2 * * * * /run2/foo.pl */2 * * * * /run3/foo.pl */2 * * * * /run4/foo.pl A snippet of foo.pl is as below: use Fcntl qw(:flock); use autodie qw(:all); open my $self, '>', "$FindBin::Bin

问题 I have created a cluster consists of three RabbitMQ nodes using join_cluster command. i.e. rabbitmqctl –n rabbit2@MYPC1 join_cluster rabbit2@MYPC1 (currently the cluster runs on a single computer) Questions: In the documents it says there is one implemetation for active passive and one for active active. What did I configure? How do I know? How can it be changed? Is there a big performance trade off between Active Active & Active Passive? What is the best practice to interact with active

问题 I am making a script with 2000 jobs in a day using cron (means that is server side and automatically do all jobs.) but the job require to run simultaneously 10 (or specified no. of jobs ) jobs . like if u see IDM(internet download manager ) there is a queue function it run multiple jobs at a time and if any complete it start another . i want something like this .. how can i do this ? 回答1: You can either go ahead and write your own custom job queue handler. Spawn a separate process per job,

问题 I m having problem with tensorflow reading images in using queue. Please let me know what mistake i am doing. Below is the code. import tensorflow as tf slim = tf.contrib.slim from tensorflow.python.framework import ops import glob filelist = glob.glob("/*.png") filelist[0] imagelist = ops.convert_to_tensor(filelist) #Makes an input queue input_queue = tf.train.slice_input_producer([imagelist],num_epochs = 2, shuffle = True, capacity = 64*3072) I have used different capacity values but none

问题 I'd like to be able to dispatch a bunch of work via JavaScript to be done in the browser in such a way that the browser stays responsive throughout. The approach I'm trying to take is to chunk up the work, passing each chunk to a function that is then queued with a setTimeout(func, 0) call. I need to know when all the work is done, so I'm storing the returned timer ID in a map (id -> true|false). This mapping is set to false in the next block of code after I have the timer ID, and the queued

问题 I'm looking to implement RabbitMQ into my PHP application, and am using the php-amqp extension. My only question is this, how do I easily query to return the contents of the queue in PHP? php-amqp seems to not enable me to do this. If I am going wrong, please help me out here :) 回答1: James, could you please ask this question on rabbitmq-discuss? Your question touches on what it means to 'query' a queue in order to get messages. In RabbitMQ you consume messages from queues, and perform

问题 Please consider the following job: <?php namespace App\Jobs; use Illuminate\Contracts\Bus\SelfHandling; use Illuminate\Contracts\Queue\ShouldQueue; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Queue\SerializesModels; class ImportUsers extends Job implements SelfHandling, ShouldQueue { use InteractsWithQueue, SerializesModels; public function __construct($number) { $this->number=$number; } public function handle() { dd($this->number); return; } } Dispatching this job using a sync

问题 I'm working an image processing website, instead of having lengthy jobs hold up the users browser I want all commands to return fast with a job id and have a background task do the actual work. The id could then be used to check for status and results (ie a url of the processed image). I've found a lot of distributed queue managers for ruby, java and python but I don't know nearly enough of any of those languages to be able to use them. My own tests have been with shared mysql database to

问题 I quickly wrote a linked list class in Java. I want to write another queue class which uses the linked list. How would I achieve this in Java? I don't fully understand the implements / extends keywords... this is what my queue looks like ( for example): public class Queue<T> implements LinkedList { protected LinkedList<T> list; public Queue() { list = new LinkedList<T>(); } public void add( T element) { list.add( element); } public T removeLast() { return list.removeLast(); } } Also note that

问题 I want to make a dashboard which shows the status of our Azure services bus queues and displays the history for "messages added to queue", "length of queue" and "messages processed" etc. Using the Azure Management Portal, I can see that most of these statistics manually for each queue. Is there any way to get access to the data that is displayed in the Management Portal through one of the APIs as I want to combine the data from number of queues that we use into a single interface. I have
