QUESTION
thank you in advance for reading and taking the time to troubleshoot this with me!
Let me first start off with the important stuff:
Target Device:
- Raspberry Pi 4B
- Electronic-Salon Relay Hat
Development Environment:
- macOS Catalina
- PyCharm
- Python 2.7.10
At my home I have a spring that serves my home with water. The solution I came up with to prevent dirty water caused by bad rainy weather loosening up the ground soil from entering my cistern is closing a valve and waiting for about 12 hours for the water to clear back up. Then I open the valve and clear water flows into my cistern providing my home with water, and that solution works really well.
I recently came up with the conclusion that I want to automate this process with a normally open solenoid. I purchased a Raspberry Pi, a Relay Hat, and an Ambient Weather weather station.
What I'm looking to do with Python 2.7.10 is check the same variable against itself after an allotted time. In this example, I'm checking the relative barometric pressure against itself and I'm wanting to look for a significant negative change in that variable.
i.e "What does variable A have? Okay, now wait 3 seconds. What does A have now? How much has it changed?"
This is what I've bodged together so far, how can I improve? Thank you.
At first I was thinking maybe I should plot a chart with the data and compare the difference between the two plot points, but I wasn't sure how to use Matplotlib.

QUESTION
I am creating a program which generates a random list of songs, and has a function such that if a user wants to save a song from the random generated list, the user should click the button next to it. Then the user can print the songs he/she saved on a new window, and then I add a function using pickle so that if the user closes and reruns the program the previously saved items are retained and can be reprinted. But an error, how can I implement this correctly
This is the code:

pickle.dump(lst, msg)

print (pickle.load(msg))
QUESTION
The code below asks you 4 yes/no questions, but you're only supposed to say yes to one of them. They go in the order as it shows below, but I want this to stop asking the questions as soon as the user says yes.
Example: You answer "yes" to the first question "Do you want to listen to hip-hop? (yes/no)" then it shouldn't ask the other 3 questions. If you say no to the first two questions and yes to the third it should not ask the fourth.
Are there any commands that I don't know? I tried using "else" instead of "elif" for the last command, but that didn't do what I wanted. Thanks!

From what I read importing both libraries seems to be the solution to a WebGL bug I ran into a bug and it seems like the accepted solution is to import like this:

QUESTION
We have a domain coolcats.com and need to add ALIAS coolcats.com to pixie.porkbun.com where our website is hosted. I don't see how to add an ALIAS record in google cloud DNS? Can I do it via an api perhaps?
...ANSWER
Answered 2020-Feb-24 at 16:30Unfortunately, Cloud DNS at the moment doesn't support ALIAS records. Have a loom at the Supported DNS record types.
You can file a Feature Request at Google Public Issue Tracker under this component. Also, as a workaround, you can set up your own DNS server inside VM like PowerDNS.
QUESTION
I have written a bash like Linux shell in C.
(Link to my repository:https://github.com/oneiro-naut/wish
.The file src/execute.c has the execute_pipeline function in it)
I am having problem implementing builtin commands which produce some output. Builtins which do not produce any output like cd and exit work just fine. External commands run smoothly. Shell has support for pipe constructs and I/O redirection as well. The problem is when I try to run a internal command( which is just printing a message). When I redirect builtin command's output to grep command using a pipe the grep child process hangs which I think is happening because grep never encounters the end of stream(or EOF) while reading from the pipe.
NOTE:This does not happen when the pipeline has only external commands in it.(I have taken care that no (external)command finishes before the next command has not yet started therefore it does not hang there)
Here is a simplified version of my problem `
...ANSWER
Answered 2020-Jan-22 at 20:23You should
1. restore the stdout in the child; otherwise the grep child process will write to the write end of the pipe which is its stdin.
Add a dup2(std_out_dup,1) just after the if(pid == 0)//child process ... {
2. add a fflush(stdout) after all those .... printf("Pain of Salvation\n"); printfs; otherwise the stream will be flushed twice.
3. close all writing ends of the pipe in both the parent and the child; add either dup2(std_out_dup,1) or close(1) before the wait loop in the parent.
QUESTION
In my Django project, I have a JS library that also uses SVGs for icons. These files are in an S3 bucket - meaning not on my own domain. When the JS is initiated, it tries to load the SVG icons and that throws a browser error in Chrome:
...ANSWER
Answered 2018-Aug-26 at 13:42Currently, there doesn't look to be a way around this issue on the framework/CORS level. The only way to load an external SVG from a CDN is via a rather unseemly Ajax call.
It's nothing you've done wrong - more a fundamental problem: the tag's xlink:href will NEVER load content from a remote server, even with Cross-Origin Resource Sharing turned on.
To load the SVG via an XMLHttpRequest you'll need to do something like the following:

I recently found out about pixi.js via github and am intrigued.
I used npm install pixi.js --save and pasted in the example code from the github repo, but I was returned the following error:

Answered 2019-Jul-27 at 15:55Usually when working with PIXI you'll want it as a global dependency, so you can point a script tag at it in your index.html.
