QUESTION
I am trying to understand the usage of existentially quantifying. What I know by now is this technique is used with setof
, findall
, bagof
. Further, I found a tutorial. However, I am not sure when and how I do the Vars^Goal
(existentially quantifying) in Prolog.
Here is the example, my goal is to find two employees who know each other but work at different companies, binding the result with L
showing Name1-Name2

Answered 2021-Jun-14 at 12:48I am not sure when and how I do the Vars^Goal (existentially quantifying) in Prolog.
The easiest answer is: Don't do it, ever. You can always introduce an auxiliary predicate that captures exactly the query you want, exposing exactly the arguments you want and nothing else (that would require quantification), and with a nice self-documenting name.
In your example, you can define:

Have a dataset like below and would like to know various ways to solve the question of : what % of orders were within 20 minutes of each other?
CustomerId Order_# Order_Date 123 000112 12/25/2011 10:30 123 000113 12/25/2011 10:35 123 000114 12/25/2011 10:45 123 000115 12/25/2011 10:55 456 000113 12/25/2011 10:35 456 000113 1/25/2011 10:30 789 000117 9/25/2011 2:00Result set should look like this:
3/7 = 0.42%
My approach was to first do a Self join with the table to get a count of rows which fall within the 20% but struggling to take out the duplicate rows.
Anyways, look forward to seeing some crafty answers.
Thank you.

QUESTION
I have a problem with the code below. With that code, we can select specific product and give them a different style in the shop archive. This is working.
However, I guess there is a error in the code.
Once I activated the checkbox for a product, it always appears in the new style even when I uncheck the checkbox. I assume that I made a error with the get_post_meta
object.
Can someone help me with that?
Code to display the check box in the general product settings and add the class, based on the value in the check box

QUESTION
Are there any crafty tricks to mix two shaders together? i.e. to add the shaders together, else to render one shader in a central square and another as a frame? Can we rename some of the input-output parameters and add them in a final image mix meta-function?
i.e. If i change
...ANSWER
Answered 2020-May-01 at 10:42You can use the render to texture enabled by Shadertoy buffer tabs and iChannel mapping.
To do it, just add a BufA tab and put your first shader code into it, then do the same with BufB tab and your second shader code.
For example I will generate two gradient images and sum them. BufA will draw some red to black, and BufB will draw some black to green gradient.
QUESTION
I am trying to make an equal dimension square grid over a given area using R. I want my grid to be 1km x 1km square. I see examples like this which illustrate equal lat/long grids:
Creating a regular polygon grid over a spatial extent, rotated by a given angle
but that's not even size. It seems like I should be able to take the st_make_grid
function and create this, but I can't grok how to make the grid 1km x 1km.
https://r-spatial.github.io/sf/reference/st_make_grid.html
I'd like, for example, to start at (37,-89.2) and end at (36.2,-86.8) and create an evenly spaced grid that's 1km x 1km. How would I do that with R?
Note: the tricky part it seems, is keeping the grid really 1km x 1km over a very large area. I can keep the grid equal dimensions in decimal degrees, but that's not equal distance on the ground.
I've been able to do this with PostGIS, thanks to a crafty answer here. In PostGIS I've created a function:
...ANSWER
Answered 2020-Apr-20 at 13:07Consider this example; it uses the boundaries of the City of Prague for basis of the grid.
The key part is to make sure your sf
object is in a metric CRS (or a feety one if you are an American and feeling patriotic); it does not matter which as long as it is in a projected CRS (i.e. st_is_longlat(x)
returns FALSE
).

QUESTION
We have an ASP.NET .NET Framework 4.7.2 project. Unfortunately, we want to reference newer Nugets, which inevitably drag in .NET Standard, or worse yet, Core. Every time we want to include a new Nuget, it's like playing Russian roulette with the project. Most of the time, it will result in some version of:
You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
Today, it happened during compilation of a view, after referencing a .NET Standard project.
As there are multiple System.Runtime DLLs, from .NET Framework, Standard, or Core, and Visual Studio can't tell which one to put in the bin folder. Usually it defaults on Framework from the GAC.
Failed Solution:
We have tried all sorts of things, primarily in our web.config:
ANSWER
Answered 2019-Aug-04 at 23:26Although I have seen System.Runtime missing in many places, at this current moment, it was blowing up when loading a view.
Little did I know, apparently the view engine doesn't necessarily use the same assemblies as the main project! See my answer in another post for how to add assemblies to the view engine: https://stackoverflow.com/a/57350759/2589506
QUESTION
Quick overview: The application uses Google's Speech-To-Text to realtime convert the microphone input to text. Because of this, the API key has to be (?) on the cliënt's computer.
It's a webapplication embedded in Electron, so that it has access to the local file system and can start the server that communicates with Google's API. It then sends the received data to the webapplication via a websocket.
What I just realized was that no matter what language I write the server in, a very crafty user might be able to retrieve the API key from the code. How do I protect that key?
...ANSWER
Answered 2019-Jul-31 at 15:05I found some documentation about "Securing an API key" on Google Cloud Platform documentation that could be helpful for you.
Based on this documentation, is recommended to not use API keys directly in your code or in files inside your application's source tree. Instead, you can store them in environment variables or in files outside of your application's source tree.
Hope this helps you!

I want to make a mobile device to scroll to a certain position and then output it as an alert. My code works fine in chrome on my PC but not on mobile devices. When I run developer tools in chrome on my PC and select view on mobile devices it doesn't work, even though it works fine in the PC view mode. If I set the position to say 30 pixels the screen doesn't move at all, in mobile device view, and the alert comes back with zero. What am I doing wrong?
