Variable for whether having, for example, the variable for if the user has points, which is correct?
have_points, has_points, if_having_points or if_has_points?
Naming convention for a variable which holds boolean value should be indicated by prefixes like: is, has, have, does, will, can etc.
In your case you're using snake case. If "has Points" is being tracked for a single entity then you can go with has_points. For more than one entity you might want to go for have_points.
Although it boils to personal preference, but you should still try to keep your code short and succinct.

If I want to create a long sequence (at least ten) of yes and no questions in dialogFlow, using webhook to store results, do I need to create an intent for each question or could this be done programatically from the webhook somehow, enforcing the order of the sequence in a better way and possibly making the code less extensive?
A sequence of questions like:
Is cucumber a fruit? Yes/No, Are there flying fish? Yes/No, e.t.c.

The search algorithm I'm implementing (a simple partial order planner) just has a few choices to make at each invocation. Ideally I would like it to backtrack over the possibilities and return the first found solution.
Take a look at the list ([]) monad instance. It's commonly used for non-determinism.

Experimenting AntiXSS in ServiceStack. I saw you have lots of work put into AntiXsrf namespace. I added token in form, tried AntiForgery.Validate using global and request filter, all seem work fine.
Also, if I use request filter, is there a way to decorate auth/credential? Since I also has a CustomAuthProvider, I can authService.RequestContext.Get() and run validate separately if necessary.
Just want to verify this is the right approach, or in case you already have something built in that I missed.
BTW, is stackoverflow the preferred place to ask all these amateurish questions ^_^ ? Or should I ask more often in the google groups?

I know it is possible to solve a VRP problem using OptaPlanner. I would like to know if it is possible to route a Heterogeneous Fleet of Vehicles using OptaPlanner.
Yes, it's been done before.
Just change the (Vrp)Vehicle class accordingly. Currently it already has a capacity, so you can already model vehicles with different capacities. But it's trivial to add other properties (such as maximumSpeed, driverLicenseLevelRequirementEnum, safeAgainstRobberyBoolean, ...).
Then simply use those properties in your new/existing score constraints.

Perhaps a silly question, but is there any common naming convention for a class that provides thread-safe operations, other than ThreadSafeFoo? This is most explicit and works nicely, but I figured I'd ask if there are any single-word synonyms which represent the notion of thread safety ("Safe", "Locking"?), or if there's anything shorter that is commonly used?
I think Concurrent... is a good choice. It describes very well the usecase in which it should be used without saying to much about technical details..
SyncFoo can be a good choice to avoid too long class name.
