## Are XGtE subclasses compatible with the UA ranger

My games use the UA ranger instead of the PHB variant. The question did not previously come to mind, because until now my players either chose hunter or beast master, both of which have their variant in the UA. Now the question did come up:

Are the XGtE ranger archetypes compatible with the base ranger class from unearthed arcana?

The reason I suspect it might not (at least not as written) is the fact that extra attack got relegated to the subclasses (except for the beast master who now lacks it). I further assume that the XGtE subclasses where created with the original PHB ranger in mind which means they would suddenly be seriously downgraded because they lost the extra attack.

By compatible I mean:

1. Is it correct that I would need to add extra attack to assure that the class is balanced with other classes?

2. Are there other differences with a similar high impact that I would need to consider?

Clarification: I want to combine the base class (the part without the subclass which is common to all rangers) from the UA with a subclass from XGtE rather than one which is also from the UA.

## No authorized routine named “SQLJ.INSTALL_JAR” of type “PROCEDURE” having compatible arguments was found

My goal is to deploy a Java routine to a DB2 server. After reading Deploying Java routine class files to DB2 database servers on p.267-268 of IBM DB2 10.5 for Linux, UNIX, and Windows Developing User-defined Routines (SQL and External) I issued the following call in IBM Data Studio:

call sqlj.install_jar('file:/C:/Projects/javadb2.jar', 'javadb2'); 

where C:/Projects/javadb2.jar is the path on the DB2 server machine to the JAR to be deployed to its local filesystem. It throws the following error:

No authorized routine named "SQLJ.INSTALL_JAR" of type "PROCEDURE" having compatible arguments was found.. SQLCODE=-440, SQLSTATE=42884, DRIVER=4.18.60

I tried under the regular user and under db2admin to no avail. The only question that I found for this error on SE was where they added a 3d parameter, so this is not my case. Anyhow, with or without the 3d parameter of 0, it still fails with the same error message.

## Is the Psi Warrior Fighter’s Psionic Strike compatible with the Brace Combat Maneuver?

Psionic Strike. You can propel your weapons with psionic force. Once on each of your turns, immediately after you hit a target within 30 feet of you with an attack and deal damage to it with a weapon, you can expend one Psionic Energy die, rolling it and dealing force damage to the target equal to the number rolled plus your Intelligence modifier.

Brace. When a creature you can see moves into the reach you have with the melee weapon you’re wielding, you can use your reaction to expend one superiority die and make one attack against the creature, using that weapon. If the attack hits, add the superiority die to the weapon’s damage roll.

I would imagine not considering the "once on each of your turns wording" but I just want to make sure. It would be super cool if I could use Brace’s attack, stack Psionic Strike on top it and then use Telekinetic Thrust.

## How compatible are the published D&D 5e rules with the rules in the SRD?

As of the time I’m writing this question, Dungeons & Dragons 5th edition is published only in English, and to the best of my knowledge, no plans exist for an official translation into other languages. As a result, several crowdfunding projects have been launched and successfully funded to create foreign-language versions of 5E by simply translating the SRD rules.

I play D&D with a group in which half of the players don’t speak English. So I was wondering whether it would be feasible to play D&D 5e with them if I use the official published rules, and they have the SRD-translated rules. I know that the SRD rules aren’t 100% identical to the official rules, but the difference is mostly missing subclasses and races.

Are there any rules in the SRD which would actually contradict the published D&D 5E rules and make it difficult to play if some players used SRD rules and others used published 5E rules?

## Why is Kingston USB PHISON controller is only compatible with my device?

For some reason my device only accepts PHISON micro controllers loaded with firmware. I have tried other manufactures that failed. Is there a reason for this?

## Is there a name for the class of distance functions that are compatible with k-d trees?

The typical nearest neighbor search implementation for k-d trees prunes branches when the distance between the target and the pivot along the current axis exceeds the smallest distance found so far. This is correct (doesn’t wrongly prune any points) for any Minkowski distance. Is there a broader class of well-known distance functions that are compatible? Formally, I think the necessary and sufficient condition is just

$$d(x,y) \ge |x_i – y_i|$$

for $$x, y \in \mathbb{R}^n$$, $$1 \le i \le n$$.

## Which edition(s) of D&D is the Caverns of Thracia (1979) compatible with?

I am interested in running an open table along the same lines described by this Alexandrian post and I want to use the original Judges Guild Caverns of Thracia.

I can find a compatible OSR game I’m sure (I want something that has a free PDF rulebook and super-quick character creation, to suit having casual players at an open table), but I need to know what edition of D&D I’m looking for a match with. What edition of D&D was Caverns of Thracia written for and is compatible with?

## Unreal Engine: Object Reference is not compatible with pawn Object Reference

Hello I am a beginner Unreal Engine developer learning with Blueprint and I am trying to take an imported FBX model and put a pawn control on it. Below is what I am trying to do. By the way, FbxScene_Test_Character is an actor.

What can I do to get around this error? Do I need to add extra information?

## Ubuntu compatible with HP Envy 17

Brand new to Ubuntu. Just bought a HP Envy 17.3″ Touch Screen Laptop, Intel i7, 12GB RAM, 512 GB SSD. 17M-CE0013DX. A techy friend is recommending Ubuntu over Windows for security, stability, and privacy. Is this laptop compatible with Ubuntu? I did not see it on a a site listing Ubuntu certified hardware. If so which version of Ubuntu is recommended. Thanks.
