sync

问题 After reading the docs, this is my understanding of sync . I instantiate some Backbone.Model and call Collection.create() . create() eventually calls sync() and the Model is POST ed to the server. Then there is a sync in the opposite direction such that the Model on the client is given an id . Does this update then trigger componentDidUpdate() ? Note: componentDidUpdate is a ReactJS thing, so if that doesn't make sense, the question reduces to "Is the client-side model updated and the view re

问题 Sorry for abstract question, but I'm looking for some samples/advices/articles on type of applications which does some equivalent operations in cycle, and every iteration of cycle should expose its result in certain portion of time (for instance, 10 seconds). My application does synchronization of data between external WCF service and local database. In every iteration an application retrieves changes of data passing request to WCF service and puts changes to database and vice versa. One of

问题 I am working on two way sync between two databases, something like what cloudconnect.com did. I am using DB triggers to send data back and forth between the DB's. I was wondering whether I could prevent the PG database in the local from calling the update trigger when the update is done from the remote DB (preventing continuous looping). I tried using SET session_replication_role: 'replica' , which worked, but this will also violate the database integrity by disabling the column constrains. I

问题 trimming video,then I send the video trimmed to android device and play,I find audio/video out of sync, the audio is several seconds behind the video. but the video can play normal on iOS device. 1.I trim video with codes like this: - (IBAction)showTrimmedVideo:(UIButton *)sender { [self deleteTmpFile]; NSURL *videoFileUrl = [NSURL fileURLWithPath:self.originalVideoPath]; AVAsset *anAsset = [[AVURLAsset alloc] initWithURL:videoFileUrl options:nil]; NSArray *compatiblePresets =

问题 basically I got two threads running.. one broadcasts music via a network (let's call it broadcaster).. the other communicates with clients to know when to start broadcasting, play music etc.. (runs on main) The broadcasting thread keeps on running even while the server is talking to the client, there is only one part when I want to pause the broadcaster thread, and that's when I want to send a packet to the client to start playing music (ie i want both server and client to play in sync).. i

问题 I am trying to get a number of GIT repositories sync-ed with ours. As these projects come and go I decided to create one single script that I call with a CronTab in order to preform the script. I did try this by hand and it did work, however with these other repositories it did not. My Bash Script: external_repos=( "OurName.projectx" "OurName.anotherproject" "OurName.thirdproject" "OurName.stackexchange" ) for i in "${external_repos[@]}" do echo "Handling" $i TEMP=`echo $i | cut -d "." -f 2`

问题 I use egit in Eclipse to sync my code between two locations using a repository on bitbucket. I want to be able to work on the code from either location. What I usually do is commit the changes at the end of the day. Is there another way I should be doing this, as I end up with a lot of commits for code that I'm still working on that is still broken? I thought the idea was that you are meant to only commit when the code is working. What is best practice so I can update the code in the

问题 I am creating a game (a Snake Clone) as a hobby. I was looking at the dispose method from the Graphics class in the Java API. When I comment out the dispose method, My animation works the same way just fine with or without it. In the Java API, the dispose method does this- releases system resources that the graphics context is using. Doesn't the Java garbage collection manage the memory of the program similar to what the dispose is doing? Should I keep the dispose method? The API was not much

问题 I'd like to connect a HTC Desire to the pc ONLY as debugging device. Every time I plug the cable in it searches for the HTC Sync software on the pc, and it takes a looong time until finally a message appears on the phone like "no HTC Sync found, ... please install...". After that, the phone is available to eclipse for debugging. But how can I avoid that everlasting searching process? 回答1: Below is copied from this page. Works for me very well. Just remember to follow procedure described at

问题 This has been bothering me for a while so I thought I'd just do a quick QA on it: If one has a normal nodeJS module or something and it has a async function on the server side. How do I make it synchronous. E.g how would I convert the nodejs fs.stat asynchronous function to a synchronous one. e.g I have server side js Meteor.methods({ getStat:function() { fs.stat('/tmp/hello', function (err, result) { if (err) throw err; console.log(result) }); } }); If I call it from the client I get back
