pipes | 💿 Classic 3D Pipes screensaver remake | Game Engine library

A statement like this compiles without error:

I looked at the standard documentation that I would expect to capture my need (Apache Arrow and Pandas), and I could not seem to figure it out.

I know Python best, so I would like to use Python, but it is not a strict requirement.

I need to move Parquet files from one location (a URL) to another (an Azure storage account, in this case using the Azure machine learning platform, but this is irrelevant to my problem).

These files are too large to simply perform pd.read_parquet("https://my-file-location.parquet"), since this reads the whole thing into an object.

I thought that there must be a simple way to create a file object and stream that object line by line -- or maybe column chunk by column chunk. Something like

We have a NestJS project with several modules. Suddenly, some tests stopped working with errors all like

FAIL libs/backend/nest/pipes/src/lib/iso-date-validation.pipe.spec.ts

● Test suite failed to run

ENOENT: no such file or directory, open D:\git\my-nest-project\libs\backend\nest\pipes\src\lib\iso-date-validation.pipe.spec.ts'

It knows what test to run, but then it claims it can't find the test file. Sometimes we get a couple of these errors, sometimes dozens.

These errors are happening randomly (not always on the same tests) locally on my machine as well as on our Jenkins server and on other developer environments as well. I can reproduce this on Windows/Mac/Linux.

There were no changes to the test or project configuration files that would have triggered this change. In fact, I have checked out previous versions of the codebase that built reliably in Jenkins and now they have the same random test errors.

I have tested on clean nodejs environments with nothing installed globally except npm.

Using the jest --verbose flag gives me no further details.

The jest config in a NestJS project is multi-layered, so it's hard to display the whole thing here, but I don't understand how this could be a configuration issue because the tests used to run fine and the configuration files have not changed.

I have tried clearing the jest cache, but the results are not consistent. On some occasions I can get a clean test run after clearing the cache.

More often than not, the test failures occur in a module that has some React .tsx templates, but not always. Sometimes a pure Typescript module will fail.

I want to create a named pipe ("mkfifo") with .net6 in Linux.

Using the class NamedPipeServerStream doesn't help me as it creates a socket file instead of a pipe.

This creates a socket :

TL (see TL;DR near the end of the question)

I came about this data with pipes as field delimiters (|) and backslash-quote pairs as quotes (\") to fields with delimiters in the data, such as:

I'm trying to match two things inside brackets, first the string after dollar, and next optionally string after text.

First part (name after dollar) I can match using: /{{\s*\$\s*([^}| ]+)\s*}}/g (see: regex101)

However I fail at matching the second part. For second part I tried using adding the bold part to first one, but it does not work: /{{\s*\$\s*([^}| ]+)(?:\|\s*((?:(?!{{).)*?)\s*)?\s*}}/g

How can get my regex working or write one that matches both?

I tried to do it in a way so I can remove the part matching 2 and match 1 would continue matching without pipes. And if both exists, it matches both. So something like {{regex-matching-one (<>)}} so I can just remove the second regex inside first one it still works.

I contribute to a non-profit open-source project and will use the regex for it.

I have a list that I need to separate with a | character, but I don't know how to make it so that the character doesn't appear after the last item in each line.

The current project looks like this:

I am trying to implement a pipeline that has an optional step which consists of a pipeline of several functions. It runs this pipeline based on a condition, and otherwise it just passes through the original value. However I've tried implementing this using if and also purrr::when, but in both cases the positive case simply returns the pipeline instead of executing it.

Here's a simple contrived example. I've simplified the conditional pipeline to only one function, but being able to use magrittr pipes inside the TRUE branch is important here.

I was following a tutorial with tech with time and at the end of part 4 every thing was working, part 5 just explains neat then there was implementation of neat in part 6 and by the time we tested the code again half way through part 7 (the last part) it was not working properly but no error codes.

I have tried moving the pygame.display.update() to different locations and it does not seem to help.

I have tried changing the draw order so that the birds are drawn first and then the pipes and it did not seem to help.
