How to communicate Credit Card details to customers when instantly approved in PCI-DSS compliant way?

Would displaying the full Credit Card details (PAN, Expiry date and CVV/CVC) in Online Banking and / Mobile Banking be considered both PCI-DSS and secure? Or what would be Best practice to display the details for the instantly granted (approved) Credit card so that customer can start using it for eCommerce?

How to communicate a SWAG estimate

I support a large enterprise software project which frequently receives enhancement requests from our customer. The customer will only pay for the work up front in fixed-price contracts. We provide a SWAG estimate first, then provide a detailed estimate after they green light the SWAG. The detailed estimates are time consuming and we are only compensated for the estimation time when they sign off on the enhancement, so the SWAG estimate provides a level of protection for us.

We communicate our SWAG estimate as Small, Medium, Large, or Very Large, and we have communicated ranges associated with each of these values. For example,

Small: < 5 days Medium: 5 - 15 days Large: 15 - 50 days Very Large: > 50 days 

Having put this into practice for a couple of years, I have some concerns:

  1. Sometimes the SWAG estimate is expected to be at the high end of a range. This form of estimate can make it difficult to manage customer expectations, a 15 day effort is very different from a 50 day effort, and the customer can green light a SWAG under the optimistic assumption.
  2. If the customer approves of a SWAG estimate, we can feel obliged to cap our detailed estimate at the high range of the SWAG. If we move up a range then there are usually additional billing discussions which are painful, slow, and lacking guarantees for compensation.

Are there any kind of standard practices, or tried and true methods for communicating SWAGs that can help us better manage customer expectations?

What is the best way to communicate to a user that a pricing package is no longer available?

We currently offer 4 pricing packages, but will no longer be offering one of them.

What is the best way to communicate this to users, particularly the ones who were on that (deprecated) plan and are interested in purchasing this deprecated plan for their other accounts (note that users can have multiple accounts with a plan associated to each)?

What is the best way to communicate this before they reach support, presumably to complain about the “missing” plan?

Within the product, we also display the pricing table for them to easily manage their existing plan or upgrade to another plan. In this pricing table we display all of the plans highlighting:

  • The plan they are on
  • The plan we recommend/most popular plan

If they are currently on the deprecated plan, do you recommend we still display this column, but grayed out?

How to better communicate change of name to existing users?

Our product has in the recent years grown and I think that to a new user, a different taxonomy would make more sense. The good thing is that we don’t quite have too many existing users yet so I think this would be the best moment to do it. However, for the existing users, I’m not sure what’s the best way to inform them that only a few names have changed inside the product, while everything else is still the same?

Build a C2C server to communicate with malware

So, I have an old piece of malware that communicates with a C2C server that is no longer active. I have reverse-engineered the malware and figured the commands that it expects. It uses Http for its communication. I would like to communicate with malware so that I can receive its requests and respond accordingly. I’m new to this and would like some specific pointers. Thanks.

How to hypothesise, evaluate and communicate UI changes

I’m looking at compiling a spread sheet to compare React frameworks. (React Semantic UI, Material UI, Ant Design…).

Framework, metric...     Semantic UI                      Material UI                      Ant Design                       

There are some metrics which are un-opinionated tangible metrics (File size, Webpack Tree shaking, No. components) But these don’t necessarily communicate the value to the user.

Some things like Material UI (which I’m biased to) have really nice user feedback animations. I’d like to practice better UX and pragmatically evaluate these frameworks for our business use case.

How do I measure these very opinion oriented types of behaviours? Preferably without pushing to production. And communicate these findings to stakeholders?

Perhaps a more basic form of my question is “How to hypothesise the colour blue is better suited to our needs” How do I go about building a case for something design oriented like this.

Cannot communicate on LAN when WIFI doesnt have internet

This is pertaining to a smart phone with data.

My phone is connected to my WIFI which lacks internet currently. It is also connected to the cell network and using it for data. When I ifconfig it tells me I am connected on wlan with and rmnet at I am trying to ping a device on for purposes.

If I turn off my cell network I can ping it fine. With my cell network on its unreachable.

How do I get my android to allow me to ping while being on the cell network? I have only noticed this since the internet went out on my WIFI so its a strange and new problem.

Is the ability to telepathically communicate with a Familiar only one-way?

The most recent PHB errata clarified that the Steed generated by Find Steed can communicate telepathically with its summoner.

In the next-to-last paragraph, “communicate with it” is now “communicate with each other.”

However, there was no corresponding change in the text of Find Familiar, which still states that the summoner can “communicate with it.” Does this lack of similar change indicate that the telepathic communication with Find Familiar is one-way?

What’s the easiest way for a whole party to be able to communicate with a creature that doesn’t know Common?

My party befriended a Faerie Dragon who is now tagging along with us, but only one of us (a Dragonborn) is able to communicate with it. According to the MM, faerie dragons only know Draconic and Sylvan, and none of us know Sylvan either.

Instead of having to ask the Dragonborn to translate every time we want to talk to it, what are some ways the rest of the party can easily communicate with it? (or at the very least, my PC, who was the one who was originally interested in the faerie dragon in the first place)

The party consists of:

  • Paladin Dragonborn (Common, Draconic)
  • Cleric Half-Orc (Common, Orcish, I think maybe Dwarvish as well)
  • Wizard Forest Gnome (Common, Gnomish, Elvish, Dwarvish)
  • My PC, a Sorcerer Aasimar (Common, Celestial, Elvish)

We are all level 3. The dragonborn player keeps track of the faerie dragon’s stats and stuff, but the DM roleplays it.
