## Show ALL Permission Groups in Admin Center?

I’m quite new to using the Admin Center for my SharePoint Management needs, and I am wondering :

Is it possible to see ALL Permission Groups that have been created on my SharePoint?

We only recently started using SharePoint Online so there are not many Sites/Users actually using it yet.

Any assistance is appreciated! Cheers!

## 19.04 settings not showing up in Unity Control Center

I am trying to turn on the touchpad while typing in my Ubuntu 19.04 computer, but in Unity Control Center only 3 icons show up. They are:

1. Language Support
2. Sharing
3. Software and Updates

If I run as root, I get the first one, the last one, and Printers.

I looked for the touchpad while typing option in GNOME settings, but the setting isn’t there. How do I fix this, or turn on touchpad while typing?

## Talend for Data Integration Vs Informatica Power Center

I have worked on Informatica Power Center. I find Informatica as best ETL because its easy to work with transformations and it has seperate components ( Repository, Workflow for running jobs, Designer Studio (Mapping Designer, Source Analyser, Target Designer, Transformation Developer, Mapplet Designer) each serving specific purpose.

Whereas, In Talend I did not find ease in working with transformations aka components in Talend. Though, everythings wrapped up in one single pallette no seperate designers thing but its very difficult to work with. Even a small mapping like loading data from file to a table takes somewhat a long time to build.

        In  Talend      Source           (Built In (Manual and is            local)/            Repository (MetaData)   -> Tmap             (to map/transform/join two               or more sources)   ->  TDBOutput               (For this you need to                have a TDBConnection                 component as               well) 

This all looks a 1 or two step but configuring each and every time again and again takes time. Plus, suppose in addition to the above sequence of ids with checking in the target for duplicacy as well. It would become very difficult. I did search a lot to finally do it by Numeric.sequence... function in Expression Editor of rows in Tmap.

In Informatica, it is much more clear source -> lkp( target ) -> sequence generator – > target

So, Is is better to work with Talend or Informatica especially for ETL. I know that Talend generates java and Informatica generates Sql as the major difference. Any other difference in terms of data integration that makes Talend superior to Informatica

## Center page view google sheets

80% of the thime we are working in google sheets like this one. https://docs.google.com/spreadsheets/d/1kYHghFZTyKxz_CpME0s1SaJdFo3AG8OSeWCi7Q-bAVE/edit#gid=274025131

It would be better if the content is in the midle of the page, as shown below, but it still needs to print fast.

How can we do this?

## Application is not recognized by Game Center

Whenever I authenticate my IOS user in my Xcode simulator (iPhone X), I get the following error:

Optional(Error Domain=GKErrorDomain Code=15 "The requested operation could not be completed because this application is not recognized by Game Center." UserInfo={GKServerStatusCode=5019, NSLocalizedDescription=The requested operation could not be completed because this application is not recognized by Game Center., NSUnderlyingError=0x60000330f180 {Error Domain=GKServerErrorDomain Code=5019 "status = 5019, no game matching descriptor: ios:com.myteam.platform:1.0:1+-1" UserInfo={GKServerStatusCode=5019, NSLocalizedFailureReason=status = 5019, no game matching descriptor: ios: com.myteam.platform:1.0:1+-1}}}) 

I have an IOS certificate linked to a developer team, and used the Xcode project settings to create a Bundle Identifier with a distinct name, Automatically manage signing with my team name, and Game Center turned on under the Capabilities tab. What am I missing to connect this app to the Game Center for development? All of the old SO questions were answered by turning on Game Center Sandbox, but that is not an option in IOS anymore.

## GNOME SOFTWARE CENTER NO MUESTRA NADA

Hola soy algo nuevo en las distros linux, cuando comence note que el centro de software no me cargaba nada mas que una pestaña de extensiones, no le tome importancia ya que instalo los paquetes manualmente pero vi un post en el que en el centro de software parecia como un app store y la mia esta vacia, hay alguna forma de agregar algun source o algo? les dejo algunas capturas.

Esto es lo que tengo en sources.list

espero me puedan ayudar gracias!

## Ubuntu Software Center is buggy

I can search software without any problem. But the only category there is “Add-ons”. I already tried restarting my computer and ran sudo apt-get update & upgrade but it still only shows 1 category. Like so:

## What does a ball of center v and radius r with at most r hops away mean?

I am trying to understand what that sentence means. Intuitively, its obvious a radius ball means in a $\mathbb{R}^{n}$ with respect to some norm. Its just the following set:

 B(v, r) = \{ x \in \mathbb{R}^n : \| v – x\| \leq r\}

i.e. its just all the points that are distance $\| v – x\|^2$ away from the center with respect to some norm $\| \cdot\|$ . However, in graph theory, if we have a graph $G = (V,E)$ I seem to have a much harder time to rigorously understand what this set means. Can someone help me define this set rigorously so that there is no doubt in my mind what it means to have a radius ball with at most radius $r$ in a fixed known graph $G = (V,E)$ ? In particular this is the sentence I am having a hard time understanding rigorously:

a ball with center v and radius r is the set of vertices at most r hops away from v

For example, if I have a path from v1 to v2 to v3, then it has 3 hops. But if v1 also has v4 as a neighbor and we want a ball radius 3, does it mean that v4 should also be part of the set of radius 3 with center v1?

In fact, is the radius ball defined as follow:

 B(v,r) = \{ x \in V : \exists path(v,x) s.t.| path(v,x)| \leq r \}

or maybe it should be defined with shortest paths $\delta(v, \cdot)$ :

 B(v,r) = \{ x \in V : \delta(v,x) \leq r \}

i.e. if you can get to a node from v in less that $r$ hops then its part of the radius ball on the graph.

In particular, consider the example. If we have a bounded degree say $d$ and the graph is undirected, if we have the radius be some finite number, do we necessarily have to include everyone’s neighbor i.e. consider all the nodes in the degree?
