## Can you craft magic items without specific abilities–and therefore, requirements/costs?

Ghostwalk’s glove of the master strategist is described as follows:

This black leather glove is decorated with purple silk thread. It acts as a glove of storing and allows the wearer to use a true strike effect once per day.

Caster Level: 6th; Prerequisites: Craft Wondrous Item, shrink item, true strike; Market Price: 3,600 gp; Weight: —.

Let’s say you don’t need the true strike ability. The glove doesn’t say that the true strike effect requires a command, so it seems safe to assume it’s use-activated. As a 1st level spell (CL 1st) with one use per day, magic item creation rules imply that this ability is worth 1 × 1 × 2000 / (5/1) = 400 gp.

As such, could you craft what’s essentially a glove of storing at CL 6th with only the Craft Wondrous Item feat, preparation of the shrink item spell, and 1,600 gp + 128 XP (half of the base price of 3,200 gp, plus XP costs)?

If so, what would happen if you gave the glove a requirement that the user have at least 1 rank in the Sleight of Hand skill? Is the 10% discount based on the “normal” cost of 1,800 gp (180 gp discount, seems unlikely) or the “intended” cost of 1,600 gp (160 gp discount, seems likely), or does doing so not apply a discount in this way (seems possible)?

## Would creating undead minions be considered an evil action in PFS, and therefore earn Infamy?

Would creating undead minions be considered an evil action in PFS, and therefore earn Infamy? I’m not keen on GMing for a necromancer or anti-paladin type character, but also don’t want to deny a player’s choices outright. It seems like a necromancer (sans undead minions) is distinctly different than someone with an undead horde. This line of questioning extends to fiendish summoning, etc.

## Does Dual Wielding count as two attacks, therefore two actions?

I’m not sure if two weapon fighting and duel wielding are the same thing.

I’m very new, like first game new. What I’m wondering is: if I have the Dual Wielding Feature, do I make two separate weapon attack rolls? Or do i make one attack roll with two instances of damage.

This came up because I attempted to like stab someone with both at once, and since my whole group is new we had no idea.

## When is optimization not premature and therefore not evil?

“Premature optimization is root of all evil” is something almost all of us have heard/read. What I am curious what kind of optimization not premature, i.e. at every stage of software development (high level design, detailed design, high level implementation, detailed implementation etc) what is extent of optimization we can consider without it crossing over to dark side.

## State true or false –> x=θ(\$n^4\$), y=θ(\$n^2\$) therefore x/y=θ(\$n^2\$)

State true or false:

• $$x=\Theta(n^4)$$, $$y=\Theta(n^2)$$ therefore $$x/y=\Theta(n^2)$$.

I think statement ans is true, but the book it says false. What is the explanation?

My reason for thinking it to be true is that say for $$x$$ we have a polynomial $$n^4+\dots$$ and for $$y$$ we have a polynomial like $$n^2+\dots$$ so if we divide $$x/y$$ the highest power in the result should be $$n^2$$ and the resultant polynomial will be like $$n^2+\dots$$, so it should be $$\Theta(n^2)$$.

I’m expecting a successful unit test.

## Let n be the number of vertices of G. Recall that G denotes the complement of G. Show that a) n ≤ χ(G)χ(G) and therefore, b) χ(G) + χ(G) ≥ 2√n.

This question was on my graph theory exam and I didn’t know how to approach solving it. The question in Tex is as follows:

Let n be the number of vertices of G. Recall that G denotes the complement of G. Show that a) n ≤ χ(G)χ(G) and therefore, b) χ(G) + χ(G) ≥ 2√n.

Any tips on how to approach this would be greatly appreciated!

## Can’t get Hadoop Datanode but didn’t show any error .Therefore can’t know which is resource of error

I have a question. I’m currently taking a project to build data governance.

I have already connected master ip and slave1 ip to each other. Then, I have made ssh keys and copied.

I don’t think I have any errors about network.

Next, I tried to use hadoop as follow.

``     hdfs namenode -format ``

and I got a warning indicating

``   WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable ``

Although I got a warning sign, i don’t think it is a problem. However, I can’t get datanode after running start-dfs.sh and start-yarn even without any issue

Can someone tell me why I get this problem?
