## Is it worth buying the “Super Powers Companion 2nd Edition” if I have 1st Ed. and the free changes supplements?

I own the original SW: Super Powers pdf that came out some years ago, however my group and I have been playing with the PDF that Pinnacle released with the rules for power creation.

I’d like to know if the changes in the second edition are significant enough to consider buying it, since I haven’t been able to find a list of the chapters of the book to know if there’s anything special beyond the rules changes on powers, such campaign creation advice, how to make heroic NPCs and villains, etc.

## What happens when a creature with Racial Hit Dice changes creature type?

The specific example I’m working with is a creature with RHD who takes the Human Heritage feat… and then advances by HD.

The creature retains all the traits of its previous type (so far so good), but what happens to its existing RHD? Do they change to the new type, or stay the same? The SRD says:

…but most templates that change Hit Dice change only the creature’s original HD and leave class Hit Dice unchanged.

However, this is in the context of whether class HD change when there is already an HD change happening, so I don’t know if it should generalize to "HD changing is the default".

If the creature then advances by gaining more HD, I assume that all the new HD would be of the new type, but I’m open to peoples’ opinions on this as well.

Bridging the two questions, there’s also an argument to be made that since Human Heritage is a 1st level only feat, all RHD are acquired after it is taken, and should thus be of the Humanoid type.

## How to securely allow email changes to user profile [closed]

How do I securely allow users to change their emails if they lose access to the original email? Do I need 2 factor?

## How to check effeciently that some changes preserve the topological ordering?

I have an acyclic directed graph with $$k$$ connected components. I also have a topological ordering $$L$$ (a sequence of vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering).

So, let’s say for example $$L = i_0,i_1,..,i_n$$.

I have the following operations:

1. Exchange(i,j): it simply exchange the positions of i and j in the list. Meaning that $$L = ..,i,..,j,..$$ becomes $$L’=..,j,..,i..$$

2. Inserting(i,p): it simply remove $$i$$ from its position and inserts it in position $$p$$. Meaning that we have $$L=a,b,c,i,d,e,f$$ then inserting(i,6) gives $$L”=a,b,c,d,e,i,f$$.

Now how to check that $$L’$$ and $$L”$$ are also valid topological sorting? Apart from doing a graph traversal of course because I want to exploit the two facts: i) the graph comes in $$k$$ connected components and ii) some parts of $$L$$ remain unchanged in $$L’$$ and $$L”$$ so its not useful to check them. Please consider indicating the complexity of your approaches.

## Detecting changes in surrounding Wi-Fi networks

I’m considering developing a simple WiFi scanner and logging App that can run as a service 24 hours a day for months passively collecting changes in the surrounding wireless environment with the following features:

• Log changes to BSSDs, ESSDs SSIDs, signal strength, number of clients, etc.
• Displaying everything on a simple dashboard;
• Notifications of new access points setup in the surrounding area;
• Notifications of new WiFi clients;
• Possibly capture handshakes (though that’s not a primary objective);
• Run on a low cost platform such as a Raspberry Pi with a simple `apt-get install` to get it started.

I’m very well aware that other solutions exit such as Kismet Logging but I don’t want invest too much time recreating a solution that already exists. Is there something that already does all of this, or a combination of tools I can try? E.g. Kismet & Kibana in a Docker image?

## Child theme stylesheet not reflecting the changes

I have created a child theme and the website is showing up properly with the activated child theme. I made some changes in the child theme’s php files for adding two controls in the child theme’s Appearance –> Customize section which will add a button ("Download my cv" button) on the home page. To do this I have added two php files and made modifications in them, keeping the same folder structure as the parent theme. They are working perfectly locally but not on the server. Although in localhost I have made the changes directly on the parent theme files.

I also can see the child theme’s style sheet is loading by view source but on making modification in the style sheet its not showing the changes. Whereas any modification in functions.php is working. Some help would be appreciated. Please check the screenshots. Thanks

## Time to FCP changes based on order of and tags

I was troubleshooting why one particular page took a full second longer to reach FCP compared to similar pages for mobile according to Google’s Page Insights. The difference ended up being the order of two tags at the beginning of the page.

3.4 seconds to FCP

``<h2>heading</h2> <p>some paragraph</p> ``

versus 2.5 seconds to FCP

``<p>opening paragraph</p> <h2>heading</h2> ``

In the first scenario, Google Page Insights gave a logo from the header as the FCP content. But with the second scenario, Google would display either text from the `<p>` or `<h2>` tag for the FCP content.

Why would the order of these two simple tags change the FCP content from text to an image header?

## What happens if a sender changes the TCP window size over multiple packets that have the same ACK number?

I’m currently doing research on evasion attacks that seek to bypass a Deep-learning based Network Intrusion Detection System.

In order to achieve this, I need to know what the constraints are for the TCP window size field in the TCP packet header. Imagine a client has just sent the last TCP-ACK packet to a server in order to complete the 3-way handshake. He then immediately proceeds to send a GET request to the server (these 2 packets are thus sent one after the other, and contain the same ACK-number).

What happens if the TCP window size in the TCP-ACK packet does not match the window size in the TCP packet containing the GET request? Will the receiver simply observe the last value for the window size that he obtained? Or will there be a violation in the TCP protocol in any way? You can assume that the change in window size is very small, and will not cause the buffer to be full.

More generally, if the client sends N uninterrupted packets (e.g. a heavy-load POST request), can he change the window size in each packet header without repercussions?

## UTL_FILE direcotry name changes oracle 19c

I’ve scripts where `UTL_FILE.FOPEN` is used and the parameter passing for directory is an absolute path i.e., `/asr/file/path` and the corresponding oracle directory name as `ASR_ABC` but after up-gradation to oracle 19c the parameter is expected to be direcotry name `ASR_ABC` instead of absolute path `/asr/file/path`.

If I pass an absolute path I get error as `Invalid path`.

Do I have to change all the files from absolute path to directory name? or is there any work around which can be done from database to avoid changes in all files?

## WE have made changes on TEST server but it is impacted on PROD SQL server

We have 2012 SQL SERVER(PROD), client cloned a Test server from PROD, For testing the Upgrade process.

While performing the SQl server upgrade we have restarted services on TEST, after restarting the services Report server schema version is changed from 163 to 164 on PROD. We got SSRS connection issues to fix the issues we have changed the report server schema version to 163 on PROD.

We are confused that we have restarted services on TEST but report server verion changed on PROD how it happens
