I have found the extension VK_LAYER_LUNARG_device_simulation to be a godsend in replicating issues found on other devices - I'm using an RTX 2080 and have been able to successfully replicate an issue on an AMD 5700.

However, for fun I thought I would try using a device file for the same model device I have, and I am getting buffer mapping errors, specifically ERROR_MEMORY_MAP_FAILED when trying to map a buffer that has been successfully created, of size 65536 bytes).

There is no such error when not using the device simulation layer. I don't have the memory mapping failure when using the amd 5700 simulation file.

Any ideas on whether this is a false positive, or something I should look into more deeply?

I've since found the debug output flag for device simulation (environment variable VK_DEVSIM_DEBUG_ENABLE=1), which lets me see some warnings about some json values being higher than existing, the only pertinent ones seemed to be heap sizes, which are zero when loaded.

If I set the heap size to zero in the file, I can't allocate anything because the heap is then restricted to zero size.

If I remove the section VkPhysicalDeviceMemoryProperties from the file, I don't see the issue.

I've now cross posted on the LunarG issues page, so there is some more detailed output here.

I'm trying to find a convenient way to change value in a column, based on conditionals in other columns, so that when there's an NA and the conditionals are met, it will replace the value. I have about 6 columns, which are like A:D, and then one binary column. There's also other data related to these specific rows, eg(date, location etc.)

I've made some dummy code below

I am attempting to store large amounts of transit data in a PostgreSQL database, where a client uploads multiple records at a time (in the tens of thousands). I only want one arrival time per stop, per route, per trip and the unique identifier for that stop, route, and trip is the primary key for my table (and a foreign key in a different table). I am trying use Django's update_or_create in my serializer to either create the entry for that arrival time or update the arrival time with the latest data if it already exists. Unfortunately, while calling is_valid() on my serializer, it identifies that the repeat records violate the uniqueness constraint of the primary keys (which makes sense), giving me this error message:

Ok, this is about to get really awesome and productive now. I ran into two more issues after switching to css(which is pretty cool and I like it!! so thanks!!).

My same repo is now updated to my css changes https://github.com/deanhiller/codenameOneExamples

This document here has been amazing(a godsend)...

QUESTION 1: I am using the same image as before and it blows up with an exception

I am self taught in VBA, which is probably the worst kind, and I still consider myself a novice. There are some things I just can't understand and this site has been a godsend. This code is not my own, so I barely understand what it is doing, which makes it difficult to alter. It's been working for the past two years. The company is now slowly upgrading computers and we now have some running Office 2010 and some running 2013. That means I can no longer use Office Tool references in my code, because it breaks between systems. So long story short, I need to do a late binding on this bit of code and I have no idea how. I get an error on msoFileDialogFilePicker and msoFileDialogViewList Please Overflow community, HELP!

I have an large messy dataset but want to accomplish a straightforward thing. Essentially I want to fill a tibble based on every combination of two columns and sum a third column.

As a hypothetical example, say each observation has the company_name (Wendys, BK, McDonalds), the food_option (burgers, fries, frosty), and the total_spending (in $). I would like to make a 9x3 tibble with the company, food, and total as a sum of every observation. Here's my code so far:

I have three classes. Let's call them Post, PostVersion, and Tag. (This is for an internal version control system in a web app, perhaps similar to StackOverflow, though I'm unsure of their implementation strategy). I sort of use terminology from git to understand it. These are highly simplified versions of the classes for the purposes of this question:

So last year, someone introduced me to an off-the-shelf database server package/ technology that would take a request from a client and would serve up the information in a JSON format that was defined in the request. Having previously had to develop mobile client applications using apis designed for websites, this seemed like a wondrous thing. Being able to make one call and receive only the data you asked for and in the format that suited your code would be a godsend.

Unfortunately, I didn't get the opportunity to work directly with the technology and I have subsequently forgotten what it was called. Neither Google nor StackOverflow has been my friend. It's difficult to formulate the search terms to get the right hit I suppose. Nobody I currently work with has heard of this and I have lost contact with the people who originally introduced me to it.

It's driving me nuts. Does anyone know the name of this package?

I have a bit of an architectural question I hope you fine people could shed some light on. At my company we want to utilize graphql, were on the same page about that. But, there are some folks in our organization who insist on having whats called a backend-end-for frontend (BFF from here on out, you can familiarize yourself here if not familiar: http://samnewman.io/patterns/architectural/bff/) for our individual frontends instead of letting the front ends themselves query the graphql server for what they need. They then want to expose REST endpoints for the frontends, where the bff is this interim layer to the graphql server. So it would look like this: Frontend 1 =====>RESt====>BFF for frontend 1=======>graphql. They want that bff to be a restrictive subset of the entirety of the graphql backend. So , my question to you all is kind of two fold. 1. Is this even reasonable given we can restrict queries via authorization and 2. If I have to deal with this, is it entirely doable to make that BFF a graphql service that has the same schemas they had hoped to expose via rest, and have that use graphql as well to aggregate from the "far backend". Graphql is a godsend for clients, so I would love to use it over still constructing http request for endpoints unnecessarily. Im open to any and all advice, even those indicating that what I would prefer is not as ideal as what they are suggesting.
