问题 I'd like to know the implementation reason for this: package main func main() { c := make(chan struct{}) go func() { print("a") for { } }() go func() { print("b") for { } }() go func() { print("c") c <- struct{}{} for { } }() <-c } ❯❯❯ GOMAXPROCS=2 go run sample1.go ab <--- blocks. package main // static void loop() { for(;;); } import "C" func main() { c := make(chan struct{}) go func() { print("a") C.loop() print("x") }() go func() { print("b") C.loop() print("y") }() go func() { print("c")

问题 In my project I have to use Quartz but I don't know what i do wrong. JobFactory: public class IoCJobFactory : IJobFactory { private readonly IServiceProvider _factory; public IoCJobFactory(IServiceProvider factory) { _factory = factory; } public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler) { return _factory.GetService(bundle.JobDetail.JobType) as IJob; } public void ReturnJob(IJob job) { var disposable = job as IDisposable; if (disposable != null) { disposable.Dispose(); } } }

问题 I want to design a lottery scheduler and I need to have a very good (pseudo) random number generator similar to LCG but I was wondering if there are other better choice out there or not? I am specifically looking for random generators written in C. LCG code: unsigned long lcg_rand(unsigned long a) { return (a * 279470273UL) % 4294967291UL; } Also I would like to know if srand() can be used for this purpose or is not highly accurate? 回答1: If you need simple but decent quality, I would use the

问题 I use the fullcalendar Scheduler add-on (http://fullcalendar.io/docs/scheduler/) When I use the code below, this background event is not coloured silver in Safari / Firefox /IE (no color at all...). It shows the silver color perfectly in Chrome. $('#calendar').fullCalendar({ events: [ { start: '2016-04-01 06:00', end: '2014-04-01 10:00', rendering: 'background', color: 'silver', resourceId: 1 } ] }); How can I fix this issue? Thanks in advance! Kind regards, Kim 回答1: You can set the className

问题 So I have a sbatch (slurm job scheduler) script in which I am processing a lot of data through 3 scripts: foo1.sh, foo2.sh and foo3.sh. foo1.sh and foo2.sh are independent and I want to run them simultaneously. foo3.sh needs the outputs of foo1.sh and foo2.sh so I am building a dependency. And then I have to repeat it 30 times. Let say: ## Resources config #SBATCH --ntasks=30 #SBATCH --task-per-core=1 for i in {1..30}; do srun -n 1 --jobid=foo1_$i ./foo1.sh & srun -n 1 --jobid=foo2_$i ./foo2

问题 I have just upgraded my application from play framework 2.3.9 to 2.4.6. Everything is working fine, but onstart(Application app) method getting executed twice. As i have created some scheduler in the onstart method, they are also getting executed twice. Global.java public class Global extends GlobalSettings { public void onStart(Application app) { Logger.info("Application has started"); JPA.withTransaction(() -> { if (ConfigHelper.getGlobalValue("install").equalsIgnoreCase("xyz")) { Logger

问题 I am trying to implement a scheduler which will run every 24 hours for my java application. The scheduler is associated with Mongo DB records. I would like to delete the files which are named exactly same as the ID of Mongo DB auto deleted documents . I think scanning the whole documents of a collection and cross checking with the file names would not be the good solution. What is the best way to do? I have tried using the logs of profiler but, It is not storing the auto deleted records. 回答1:

问题 I have a Java application which utilises Quartz 1.6.6. It is deployed onto Weblogic, the architecture of which includes two application servers. The application includes a trigger process which runs regularly - once a minute. This is achieved using Spring 3.1.1 (with a org.springframework.scheduling.quartz.SchedulerFactoryBean). I have included a quartz.properties file in the Java application's EAR file with a hope to be able to utilise Quartz's clustering facilities so that the application
