usability – How to support a "Save draft" in an assisted approach when the user takes a long time to perform a step?

I have a simple user workflow, in which the user has to finish the process sequentially. But step 2 can take a day or more to be completed.

In the current user interface, if the user decides to finish the process later, he can click "save" to skip the process and he will be directed to the summary page. The user can save the entire process as a draft. When the user comes back to edit, there will be no wizard approach. They can modify each step by individually selecting the process steps in the summary.

Is the approach intuitive? Are there any other templates for managing draft backups in a wizard approach?

dnd 5e – What can an invisible PC do to perform the "Help" action and stay invisible?

My wizard ally wants to become invisible and use the "Help" action to help attacks while remaining invisible. My DM ruled that a physical interaction with the enemy would constitute an action that breaks invisibility.

I thought I would use the same action on my invisible pet. What could they do especially not to break in an invisible way?

Perform a CSRF attack when the CSRF token is sent in the custom request header

I found that the web application uses a weak algorithm generate CSRF TokenThe CSRF token is sent in the header of the request

X-CSRF-TOKEN: "Token chain"

Since the query header is used, how to perform a CSRF attack to perform a sensible action in real time?

Custom headers can be sent using JS, but they are blocked due to CORS. I've seen few topics mentioning ActionScript in Flash that can be used to send custom headers. Does it work again? (Whereas chrome has stopped using Flash). Is there anyway I can perform the attack?

mysql – How to store API JSON data and perform searches efficiently

I display the documentation with the help of Swagger, but the documentation being long, I created a side menu and split the data into the database. By splitting it, it allows me to search specific areas and endpoints of the documentation and display it, and to only display what is selected instead of everything, every time.

There are different versions of the documentation, so some information overlaps. I'm not sure that the best way to store this, and currently it is separated by a version of the same documentation but there is a lot of redundancy because a lot of data overlap compared to previous versions.

Currently, the structure looks like this:

api_data table

search (keywords to index)

api_data_overhead table


api_product_versions table


The file overload contains a lot of common information for each path to this documentation file. It is very long but does not need to be indexed or searched.

I am looking for a way to improve the design of this database as it develops and new documentation is added. I am concerned about performance when searching and downloading data. There are a lot of redundancies right now and I wonder if it can be better.

Can you use GetSpectrumData () + FFTWindows to perform audio visualizations in Unity 2d?

I've watched online and the tutorials are focused on Unity 3D. With the problems, I'm not sure if I can use this function and FFTWindow to create a 2D audio viewer or let the audio affect my 2D objects.

Can be done in 2D?

Thank you.

security – Is it possible to perform an offline scan of malware from the device image created using a root prompt?

I have created an image of all of my device and all its partitions (mmcblk0.img). I want to perform an "offline" scan of my device on my computer.

Are there any known projects or ways to perform an analysis, analysis, or investigation of this image for spyware or malware? Maybe an emulator built for this purpose could help here?
