I have experience using the static GTFS files which define the operating model for a specific public transport network. However my city has just release a real time feed for the bus locations and other status updates for the network.
My question is, how should I view this feed in real time and record the feed into a database. The link to the real time feed is as follows: https://gtfsrt.api.translink.com.au/
The GTFS-realtime spec now includes code samples for parsing GTFS-realtime data in a variety of languages:
https://developers.google.com/transit/gtfs-realtime/code-samples
It's a good place to start when it comes to parsing GTFS-realtime data in your favorite language.
I needed to install google's protocol buffer, then compile the gifts-realtime.proto with the protocol buffer to generate code which can then read the API source.
Install Nugget Package Google.Protobuf
PM> Install-Package Google.Protobuf -Version 3.4.1
private FeedMessage _feedMessage;
using (MemoryStream protobufMemoryStream = new MemoryStream())
using (Stream protobufStream = await _httpClient.GetStreamAsync("", "http://gtfs.ovapi.nl/new/vehiclePositions.pb"))
{
protobufStream.CopyTo(protobufMemoryStream);
protobufMemoryStream.Position = 0;
_feedMessage = Serializer.Deserialize<FeedMessage>(protobufMemoryStream);
}
In _feedMessage you have deserialize GTFS RealTime Model to persist data into database.

I am using the new XBox Live API for C# (https://github.com/Microsoft/xbox-live-api-csharp) for official access through a UWP app.
I am able to authenticate fine and reference the XBox Live user in context.
SignInResult result = await user.SignInAsync();
XboxLiveUser user = new XboxLiveUser();
Success! However, I can't seem to find an appropriate API call to return XboxUserProfile or XboxSocialProfile. Both of these classes contain URLs to the player's raw gamer pics. After reviewing MSDN documentation and the GH library it isn't clear to me how this is achieved. Any help is greatly appreciated.
The below sample should work if you meet the following pre requisits:
Reference the Shared Project that contains the API from your project and don't reference the "Microsoft.Xbox.Services.UWP.CSharp" project
Copy all source code files from the "Microsoft.Xbox.Services.UWP.CSharp" project into your project
Include the Newtonsoft.Json NuGet package into your project
Steps 1 & 2 are important as this allows you to access the "internal" constructors which otherwise would be protected from you.
Code to retrieve the profile data:
XboxLiveUser user = new XboxLiveUser();
await user.SignInSilentlyAsync();
if (user.IsSignedIn)
{
XboxLiveContext context = new XboxLiveContext(user);
PeopleHubService peoplehub = new PeopleHubService(context.Settings, context.AppConfig);
XboxSocialUser socialuser = await peoplehub.GetProfileInfo(user, SocialManagerExtraDetailLevel.None);
// Do whatever you want to do with the data in socialuser
}
You may still run into an issue like I did. When building the project you may face the following error:
Error CS0103 The name 'UserPicker' does not exist in the current
context ...\System\UserImpl.cs 142 Active
If you get that error make sure you target Win 10.0 Build 14393.
I'm using TFS 2015 rest api in order to retrieve build definitions and builds details using those calls:
definitions:
http:///tfs/DefaultCollection//_apis/build/definitions?name=ampm&api-version=2.0
builds:
http:///tfs/DefaultCollection//_apis/build/builds?definition=DigitalVault_Automation&statusFilter=completed&$top=10&api-version=2.0
I get a rich JSON and I wonder if there is a standard Class that I can deserialize those JSONs to.
Couldn't find any reference in Microsoft's guide though.
You could use install this Nuget package for your project and in the package. The assemblies in this package has already help you transfer the json data to the corresponding object. For example, to get something about build, you could use the Microsoft.TeamFoundation.Build.WebApi assembly. To get a build definition:
var u = new Uri("http://serverName:8080/tfs/MyCollection/");
VssCredentials c = new VssCredentials(new Microsoft.VisualStudio.Services.Common.WindowsCredential(new NetworkCredential("userName", "password", "domain")));
var connection = new VssConnection(u, c);
var buildServer = connection.GetClient<BuildHttpClient>();
BuildDefinition builddef = buildServer.GetDefinitionAsync("AgileMttGreen",10).Result;
Console.WriteLine(builddef.Name);
I use Json.NET to manipulate JSON data.
You can find plenty of examples in this library web site.
I am learning PhoneGap for an app project and need to use the database for certain aspects, I am trying out the Nova Data framework,
https://cordova.codeplex.com/wikipage?title=How%20to%20use%20nova.data
I am trying to use my code to put together a test entity, but I am getting a db error telling me there is a missing table. The documentation does not specify that the database should be created beforehand, but I am starting to think that may be the case. Has anyone out there used the Nova framework in a project? I just need a little guidance.
Here is my code I am using to kick off the DB Context:
var DataContext = function () {
nova.data.DbContext.call(this, "HealthDb", "1.0", "Health DB", 1000000);
this.Temperatures = new nova.data.Repository(this, Temperature, "Temperatures");
};
DataContext.prototype = new nova.data.DbContext();
DataContext.constructor = DataContext;
And my entity (Temperature) :
var Temperature = function () {
nova.data.Entity.call(this);
this.Value = 101;
};
Temperature.prototype = new nova.data.Entity();
Temperature.constructor = Temperature;
It is creating an empty database with the proper name, just no tables! I am grateful for any assistance!
Thanks for using our library. I have made the html5 sqlite as a standalone library. Please get it from github.
A live demo link is also available there. And the documentation is more complete. The lib itself has also been updated and a few bugs fixed.
Thanks,
Leo
Turns out I was trying to start up the dbcontext before I defined my entity classes....
Changed the order of my js files and it works.
Please excuse me if I use incorrect terms or concepts. Seems I am in the mist of a crash course on MS Project, Project Server, and the PSI...
Project Professional provides the Resource Usage view that lists a given Resource, the Tasks they have been assigned to, and the amount of scheduled Work for a given day.
Is this information available in Project Server and how would I read it using the PSI?
Thanks.
Jason
If you're just getting started with PSI, I'd strongly recommend downloading and using the ProjTool app that is part of the Project 2007 SDK.
I haven't done too much work with Resources, but after taking a quick look.. here is how I'd approach it:
Reference the Project.asmx service (ex: http://servername/pwa/_vti_bin/psi/Project.asmx)
Use the ReadProjectEntities method to retrieve a DataSet and pass it a ProjectEntityType of Task, Assignment and Resource.
Define some entity types:
public const int ENT_TYPE_TASK = 2;
public const int ENT_TYPE_RESOURCE = 4;
public const int ENT_TYPE_ASSIGNMENT = 8;
Then you can read the data:
int entity = ENT_TYPE_TASK | ENT_TYPE_ASSIGNMENT | ENT_TYPE_RESOURCE;
ProjectDataSet dataSet = project.ReadProjectEntities(projectUid, entity, DataStoreEnum.PublishedStore);
// do stuff with these tables...
//dataSet.Task
//dataSet.Assignment
//dataSet.ProjectResource
ReadProjectEntities is nice because you can read only the part of the project you need... if you need more than the Task table then you can use a logical OR to get additional ProjectEntityTypes.
As for the assigned work, it looks like that is also in the Assignment table, but I think you'll have to do some calculating.
