sync

I am using the jQuery trigger method to call an event... but it behaves inconsistently. Sometimes it call the event, sometimes it does not. <a href="#" onclick=" $(this).trigger('custom-event'); window.location.href = 'url'; return false; ">text</a> The custom-event has lots of listeners added to it. It is as if the trigger method is not synchronous, allowing the window.location.href be changed before executing the events. And when window.location.href is changed a navigation occurs, interrupting everything. How can I trigger events synchronously? Using jQuery 1.8.1. Thanks! EDIT I have found

GOAL: What I'm after is to get data from database and refresh main.php (more evident through draw_polygon) every time something is added in database (after $.ajax to submit_to_db.php). So basically I have a main.php that will ajax call another php to receive an array that will be saved to database, and a json call another php to return an array will be used by main.php. $(document).ready(function() { get_from_db(); $('#button_cancel').click(function(){ $.ajax({ url: 'submit_to_db.php', type: 'POST', data: {list_item: selected_from_list}, success: function(result){ ... get_from_db(); } }); });

Short version: Problem: I need several Android devices to do something at the exact same time (within ca 100 milliseconds). For example, I want all devices to play a certain sound at previously determined point in time. Question: Could I use GPS time to make sure the devices clock's are synced? Longer version: Several people having Android devices are in the same outdoor location (for some specific sports event). All devices should signal certain events at the exact same time. (What time will be determined before hand and it is not important that they do it at exactly that time, as long as

This question already has an answer here: Synchronizing client-server databases 5 answers I'm working on a project containing web app and mobile app which records daily user's data. User are able to delete, update their data and they can use many devices to insert data. I intend to develop this way: User enter their data and then insert to SQLite. A service will start periodically (each 5hr or sth) to sync with MySQL using timestamp. I did search for a sample using service and timestamp on the internet but I found nothing. It would be great if there are a sample or tutorial. I'm new at Android

I want to use Vagrant to provide a common development environment to my team. The hosts are completely different: Some use OS X, some Linux, and some Windows. Some use VMware, some use VirtualBox. Inside of the VM we want to run Linux. So far, everything is fine. Now our idea was that each developer shall be able use the IDE of their choice, and hence we have introduced a synced folder that shares the source code between the host and the VM. This basically, works as well … except for symbolic links. Inside of our source code we actually do have a few symbolic links, which is not a problem
