synchronization

According to Controlling startup order in Compose , one can control the order in which Docker Compose starts containers by using a " wait-for-it " script. Script wait-for-it.sh expects both a host:port argument as well as the command that the script should execute when the port is available. The documentation recommends that Docker Compose invoke this script using the entrypoint: option. However, if one uses this option, the container will no longer run its default ENTRYPOINT or CMD because entrypoint: overrides the default. How might one provide this default command to wait-for-it.sh so that

I would like to know if everyone knows how precise PTP synchronization can be guaranteed on Windows Server 2008. I know about this thread: What is the minimum guaranteed time for a process in windows? which discusses windows' native time and yes, this does not give any guarantees at all. But what when it comes to hardware solutions (PTP)? Are there any limitations preventing a guarantee of < 1ms? I know the processes depending on the time will be competing for CPU time but if the process DOES have CPU time when needed, are there anything else the might come in the way? EDIT 1: I added "

(5 answers) Possible Duplicate: how to sync SQLite database on android phone with MySQL database on server? I am wondering what is the best approach to updating a database on an Application. We have a mysql database that handles everything on the main server, but I want to replicate this on my app. I would like to copy the database (mysql) on the android device so that both stay up-to-date. this would not have to happen in real time, but could be scheduled once every week, or

In the examples mentioned for Out-of-order writes for double-checked locking scenarios (ref: IBM article & Wikipedia Article ) I could not understand the simple reason of why Thread1 would come of out synchronized block before the constructor is fully initialized. As per my understanding, creating "new" and the calling constructor should execute in-sequence and the synchronized lock should not be release till all the work in not completed. Please let me know what I am missing here. The constructor can have completed - but that doesn't mean that all the writes involved within that constructor

Is there a windows API that would achieve the equivalent of clicking the "Update now" button in the "Date and time properties"/"Internet time" tab (opened by double clicking the clock in the taskbar)? Is there a way to monitor when the time synchronization is triggered by windows and when it succeeds or fails? There is no API exposed by the time service, but to trigger a time synchronization you can use the w32tm command line tool. In C/C++ you can do something like this: include <process.h> ... system("w32tm /resync /nowait"); Take a look at w32tm documentation for further options. This seems

I'm developing an application for iOS/OS X and i want to sync data between them. for now I use Core Data for persistent data. I read that iCloud is not enough mature to use with core data. Is that true ? so i try to use the new DropBox sync API(to sync the SQLite file), but there's no support for OS X. Is Parse SDK a good idea? (it will also allow me to add Android support) If no, have you other solution? Thank you. i read that icloud is not enough mature to use with core data. is that true ? Yes, I've worked with it quite a bit but I cannot recommend it at present. so i try to use the new
