Interacting with OptaPlanner through CLI instead of GUI - api-design

I am looking for a way to interact with OptaPlanner directly from the command line interface (CLI) without having to use the graphical user interface (GUI).
More specifically, I am looking to pass an XML file to the Employee Rostering function, and to get the solved XML back. Ultimately, I am looking to interact with OctaPlanner from my PHP application.
Any documentation for this?
Here is some what of an example of what I which to achieve:

The UI is only for the examples. Take a look at CloudBalancingHelloWorld.java which solves without a UI.
Or, if you're looking for a more enterprise approach, use OptaPlanner Execution Server (also ASL), which exposes everything as REST api's.

Documentation of Hydra Config

Hydra provides a way to dynamically create a hierarchical configuration by composition and override it through config files and the command line, leveraging OmegaConf. I look for a recommended way to document the parameters but I could not find (a documented) one. What are best practices for that? Coming from argparse, I like the way of documenting the parameter inline, i.e. close to the code.
Excellent question! The answer is: parameter-by-parameter documentation is not yet implemented (as of Hydra v1.1, OmegaConf v2.1).
The future plans are:
in OmegaConf, expose an API allowing users to attach documentation (and other metadata) to each field of a structured config. See this open OmegaConf issue.
Once the above is complete, implement a Hydra feature allowing a parameter-specific help messages to be printed based on the parameter's metadata. See this open Hydra issue.
For now, the best we can do is to customize the general application help message (i.e. the --help command line flag).

how to develop a custom connector in SailPoint

I am novices to the field of Identity and Access management.
Till now I know, Sail point has provided the some direct connectors to integrate the known systems like LDAP, HR systems, OIM, Databases..
And sailpoint also provided the support for disconnected applications with the use of Custom connectors.
Here, My question is how to develop a custom connector..?
I do not have jar file provided by sailpoint which contain "AbstractConnector" class.
So that I can write my own class and develop..?
I also so not understand, what to do with that class?(if i have a jar)
How sailpoint will refer to that class..
Do we need to deploy that class to somewhere...
Here I am expecting the complete flow to develop and deploy the custom connector..
If anyone is working please help..
If you unzip your identityiq.war, you'll find a JAR file called WEB-INF/lib/connector-bundle.jar. This is the JAR where you'll find AbstractConnector. Once you've written your connector code, you will need to compile it and bundle it into a JAR file, which you will place into WEB-INF/lib.
Finally, you will need to update the ConnectorRegistry object (under Configuration on the debug screen) to reference the new class, which will make it available as an Application type. If it has custom connection parameters (as most do), you will also need an xhtml page that will be embedded into the Sailpoint UI to prompt the user configuring the Application.
If you have Compass access, they have a whitepaper called Custom Connectors that you will find helpful.
All that said, I encourage you to try to find a way to use an out-of-box connector if possible.
Most of the times it will be better if you use the DelimitedFile connector, you can import a CSV of identity data, and make it work within Sailpoint's workflow. You will be able to map fields, correlate accounts and create multi-valued group memberships rapidly. Of course, this means that Sailpoint will not be connected directly to the application, and you will have to develop a workflow to extract the identities and upload them. But at least, you can integrate without going the Custom Connector way.

How to use Migration Commands for Entity Framework through User Defined Code

I need to be able to perform all of the available functions that the Package Manager Console performs for code first DB migrations. Does anyone know how I could accomplish these commands strictly through user defined code? I am trying to automate this whole migration process and my team has hit the dreaded issue of getting the migrations out of sync due to the number of developers on this project. I want to write a project that the developer can interact with that will create and if need be rescaffold their migrations for them automatically.
PM is invoking through PowerShell and PS cmdlets (like for active directory etc.)
http://docs.nuget.org/docs/reference/package-manager-console-powershell-reference
The Package Manager Console is a PowerShell console within Visual
Studio
...there is essentially very little info about this - I've tried that before on couple occasions and it gets down to doing some 'dirty work' if you really need it (not really sure, it might not be that difficult - providing you have some PS experience)
Here are similar questions / answers - working out the PS comdlets is pretty involving - in this case it has some additional steps involved. And PS tends to get very version dependent - so you need to check this for the specific EF/CF you're using.

Possible to add migration using EF DbMigrator
And you may want to look at the source code for EF that does Add-Migration
(correction: this is the link to official repository - thanks to #Brice for that)  
http://entityframework.codeplex.com/SourceControl/changeset/view/f986cb32d0a3#src/EntityFramework.PowerShell/Migrations/AddMigrationCommand.cs
http://entityframework.codeplex.com/SourceControl/BrowseLatest
(PM errors also suggest the origins of the code doing the Add-Migrations to be the 'System.Data.Entity.Migrations.Design.ToolingFacade')
If you need 'just' an Update - you could try using the DbMigrator.Update (this guy gave it a try http://joshmouch.wordpress.com/2012/04/22/entity-framework-code-first-migrations-executing-migrations-using-code-not-powershell-commands/) - but I'm not sure how relevant is that to you, I doubt it.
The scaffolding is the real problem (Add-Migration) which to my knowledge isn't accessible from C# directly via EF/CF framework.
Note: - based on the code in (http://entityframework.codeplex.com/SourceControl/changeset/view/f986cb32d0a3#src/EntityFramework.PowerShell/Migrations/AddMigrationCommand.cs) - and as the EF guru mentioned himself - that part of the code is calling into the System.Data.Entity.Migrations.Design library - which does most of the stuff. If it's possible to reference that one and actually repeat what AddMigrationCommand is doing - then there might not be a need for PowerShell at all. But I'm suspecting it's not that straight-forward, with possible 'internal' calls invisible to outside callers etc.
At least as of this post, you can directly access the System.Data.Entity.Migrations.Design.MigrationScaffolder class and directly call the Scaffold() methods on it, which will return you an object that contains the contents of the "regular" .cs file, the "Designer.cs" file and the .resx file.
What you do with those files is up to you!
Personally, I'm attempting to turn this into a tool that will be able to create EF6 migrations on a new ASPNET5/DNX project, which is not supported by the powershell commands.

ldap queries in Qt

Thinking of implementing a LDAP-viewer in QML. The first step is obviously to make a Qt back-end that can handle ldap-queries. I've read the rfc1823 (ldap tutorial of sorts), but still can't understand where to begin really.
I would be interested in some Qt code that would get me started on some sample LDAP functions, for instance :
connect to a ldap server
do some simple query of any type
close the connection
Edit: code is not required if you can point me to any tutorials/guides as to how one does this in C++ / Qt
I suggest using libldap. Writing a client from scratch is a lot of work. Take a look here for some examples as a kick-off. You can easily integrate that code with Qt.
The OpenLDAP library also has some c++ example included.

Simple inter-proccess communication in Qt4

I need to make so that my application can have only one instance running at a time. Also when it's launched with a command line parameter ( like when registered to open certain file types ) it should pass the parameter to an existing instance and quit immediately without displaying graphical interface. You all probably know what I mean. The framework used is Qt 4, and it seems like it must have some facilities for that. Any ideas?
There is a Qt Solutions project doing this:
Qt Single Application
There are several ways to do inter process communication. Examples can be found in Qt's examples section.
It's also possible to implement a this sort of class oneself using QSharedMemory
(see QSharedMemory::attach() ). It's capable of being used for both determining whether other instance is already running and communicating/sending messages. Except some pointer magic and memory copying it's quite straightforward.
