As we know, Paytm has launched a Dynamic QR device to display invoice/bill QR Code image.

I have to integrate this device with a billing system(POS), where I have to send QRCode data to this device.

I have to integrate it using C#.NET

Note:- As per the device guidelines, we can transfer data from system to device using USB Port(the serial port communication) Reference

When a user signs up,
we send an HTTPS PUT request to Email Octopus
in order to add that user to an email marketing list.

This PUT request includes the following user`s data:

• email
• first name
• last name
• country

We followed the guidelines here:

We also followed the same syntax as mentioned here:

However, we get an "Invalid Parameters" response.

Any idea what are we doing wrong?

We send the following request:

I'm trying to write video analysis software to check compliance with WCAG 2.0 seizure guidelines. But, in the definition of 'general flash', it states the following:

A general flash is defined as a pair of opposing changes in relative luminance of 10% or more of the maximum relative luminance (...)

I am confused about the usage of "maximum relative luminance". It's not specified in which context we are considering the maximum. Does it refer to 1.0 luminance? Or the maximum luminance achieved in the webpage? Or something else?

I couldn't find any clarification. I would just assume that it refers to 1.0 luminance, but, if that assumption were wrong, my code would produce false negatives in flash detection due to an incorrectly high threshold.

Sorry if I'm missing something obvious or if this is the wrong place to ask.

I am new to R programming and most of my experience thus far is with using highly structured rectangular data from a .csv or .xlsx. But now I've been handed about 30 spreadsheets of budget data that look like this:

And in order to work with them, I'd like to get them into a more friendly format (not exactly tidy b/c of the Q1 to Q4 could/should be a single variable -- but I can fix that later with pivot_longer), like this:

Searching SO, the closest problem/solution I found was this: R importing semi-unstructured data CSV, but that example contains a series of structured tables that do not require the modification mine does, plus, it is a text file converting to character vectors, and I have Excel workbooks with multiple worksheets (I only need 1 of the sheets).

Here's what I've tried so far:

I'm rather new to iOS programming. But I am wondering what will happen if I intentionally create view layout constraints that violate the safe area layout guidelines. Will the iOS operating system still respect them?

Will iOS simply quietly shift all my offending constraints from view.topAnchor to view.safeAreaLayoutGuide.topAnchor? Or maybe, even worse, my constraints will simply be ignored altogether?

I migrated from Airflow 1.10.15 to Airflow 2.1.0. I followed the guidelines in Airflow docs to migrate with that release as a bridge version. Everything works like a charm but i receive the following output in the logs:

I did not experienced any bug or something at least for now. I can't find any info about this in the airflow community neither in the docs. Any idea of what does it mean? And how to mitigate it?

I have adjusted the permissions and use of location data and published it in a new release (v10004). Unfortunately, my app was still removed because the previous version does not comply with the new background location regulation (As described in the mail i got from Google: Affected APK(s): App Bundle:v10003).

I could not find a way to remove the old version, nor upload the new bundle in the old track (as recommended for example in "Google Play Team" is check checking the wrong version - Background location access not declared).

It frustrates me quite a bit that the current publicly used version complies with all the guidelines, but it is not listed in the PlayStore, just because I have no way to modify the old track in the Google Play Console. I've been looking for a solution for almost 2 months now - Google support hasn't responded for weeks either.

Has anyone had a similar situation or been able to fix this issue somehow?

Thanks a lot for any suggestions how to solve this misery!

Any guidelines available for planning and designing IAM (user authentication and permissions) for a CORDA network/Node? Is there a concept of User Role in Corda?

Valid under help centre guidelines:software tools commonly used by programmers. I would like to start PyCharm and for it to automatically open the programs I had open when I closed PyCharm in the previous session (i.e. start where I left off). I usually have several concurrent programs from very different locations, so finding them all manually is a pain. Is there a way this can happen automatically?
