kandi X-RAY | piper Summary
Piper is an open-source, distributed workflow engine built on Spring Boot, designed to be dead simple. Piper can run on one or a thousand machines depending on your scaling needs. In Piper, work to be done is defined as a set of tasks called a Pipeline. Pipelines can be sourced from many locations but typically they live on a Git repository where they can be versioned and tracked. Piper was originally built to support the need to transcode massive amounts of video in parallel. Since transcoding video is a CPU and time instensive process I had to scale horizontally. Moreover, I needed a way to monitor these long running jobs, auto-retry them and otherwise control their execution.

QUESTION
On loading the MTL file, the entire model is turning black. I have referred to this link and set the rbg parameters to 1 but that hasnt solved my issue.
three.js mtl loader renders black
Here is the code associated with it:
...ANSWER
Answered 2021-May-17 at 13:12The MTL loads the texture as a TIFF image which can't be used as an image data source. Use JPG or PNG instead.
Sidenote: You will notice that the object's material has a texture assigned to the map property but with an undefined image value. In such a case, the texture appears black.

QUESTION
I wrote this code in my tutorial file:
...ANSWER
Answered 2021-Apr-08 at 03:12You have defined var2 as a tuple rather than str. To see this for yourself, print the type of var2: print(type(var2)), you'll see that it is a tuple.
Python allows tuples to be defined three ways:
tuple(sequence)(a, b, c)a, b, c
I avoid using the third syntax because it's very easy to edit unintentionally.
You need to replace the ,s in var2's declaration with +s in order to perform concatenation:
QUESTION
I am using bootstrap 4 grid system and I have a layout like the image above, the issue I am getting is the border is not aligned at the bottom row. Since I am using nested columns in (first and second row) which are eventually four columns. But at the last row I have two columns. I need last row border to match with the above row.
Please help. Thanks Fiddle Link
...ANSWER
Answered 2021-Mar-30 at 11:35It happens because there are many nested row inside another row. So bootstrap divides nested row to 12 columns.
What we want is to create just four columns and then put content there:

Flowpups is producing updated values as you can see in my logcat
Not exactly.
The Flow is emitting the same List of the same Puppy objects. I believe that Compose sees that the List is the same List object as before and assumes that there are no changes.
My suggested changes:

toggleAdoption(), create a fresh list ofPuppyobjects and use that to update theMutableStateFlow>:

QUESTION
I'm trying to import the most common Library of Congress identifier for a list of books using Google Sheets. The XML file for the ISBN is http://classify.oclc.org/classify2/Classify?isbn=1433528525&summary=true. XML is pasted below for ease. I want to get lcc/mostPopular[@nsfa] but the formula =importxml("http://classify.oclc.org/classify2/Classify?isbn=1433528525&summary=true","lcc/mostPopular[@nsfa]") returns "Imported content is empty."
Am I entering the xpath_query wrong?
I know the link is valid because I can import the whole thing with =importdata("http://classify.oclc.org/classify2/Classify?isbn=1433528525&summary=true"), but that gives a garbled mess of data in the spreadsheet.

ANSWER
