QUESTION
I tried to cluster my dataset using K-mean, but there is a categorical data in column 9; so when I ran k-mean it had an error like this:
...ANSWER
Answered 2021-Dec-17 at 17:31To solve your specific issue, you can generate dummy variables to run your desired clustering.
One way to do it is using the dummy_columns() function from the fastDummies package.
QUESTION
I ran multiple imputation to impute missing data for 2 variables of a data frame, then I got a new data frame (with 2 columns for 2 imputed variables).
Now, I want to replace the 2 columns in the original data frame with the two newly imputed columns from my new dataframe. What should I do?
Original data frame new data frame for imputed variables
This is the code I used. Only 2 columns in this data frame are missing data, so I only imputed those two. Is that ok? Can you please suggest me a better way?

As @dcarlson recommended, you can run mice on the entire dataframe, then you can use complete to get the whole output dataframe. Then, you can join the new data with your original dataframe.
QUESTION
I'm following this article to understand how eBPF tracing works, one of the first steps is to identify the symbol for the function, example code is picked up from here: https://github.com/pixie-labs/pixie-demos/blob/main/simple-gotracing/app/app.go
However, after doing the build, I'm unable to find the symbol. Why is that the case?
...ANSWER
Answered 2021-Jul-09 at 20:59Your computeE() function will be inlined and thus the function name will leave no "marks" in the executable binary. You can use go build -gcflags=-m to see what functions are being inlined in the build process.
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:

lst = [1,2,3]
with open("test.dat", "wb") as msg:
pickle.dump(lst, msg)
with open("test.dat", "ab+") as msg:
pickle.dump(lst, msg)
with open("test.dat", "rb") as 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!

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.
