kandi X-RAY | nbd Summary
It includes an implementation of a server connection handler and a client side connector. Note that negotiation is out of the scope, the connection needs to be fully configured by the time the handler starts. It is currently used for a BUSE, but can be also used as a foundation for a full-fledged server and client implementation.

QUESTION
fmt.Print("Enter valid nbd: ")
reader := bufio.NewReader(os.Stdin)
input, err := reader.ReadString('\n')
if err != nil {
fmt.Println("An error occured while reading input. Please try again", err)
return
}
input = strings.TrimSuffix(input, "\n")
cmd = exec.Command("/bin/bash", "-c", "qemu-nbd -c /dev/", input, "/tmp/var/lib/vz/images/201/vm-201-disk-0.qcow2")
cmd.Run()
cmd = exec.Command("/bin/bash", "-c", "mount /dev/", input, "p1 /mnt")
cmd.Run()
ANSWER
Answered 2022-Mar-16 at 11:17It is possible. Code is correct, you can use cmd.String to print executed command. There is most likely error during execution.
I would recommend to use cmd.Output() and cmd.StderrPipe() for debugging.

I want to print code without \n on the result.
This is my code
ANSWER
Answered 2021-Aug-27 at 13:21I had this same problem and I got an answer here.
It's is because the line you read is always followed by a \n character. You need to remove it. Hence, just replace that last part of your code with this. .strip() will do for you. str(current_location).strip("\n")
Whenever you read a line from a text file, it adds a \n character to tell that new line started from there. You need to remove that while printing or it will mess up with your current statement
QUESTION
I'm new to vs code, really impressed for the most part. One minor nit that I haven't found a solution for: with Sublime Text, and other editors, if you have an editor window already open, and do File->Open for a folder, it will open a new editor window for that folder.
With vs code, it adds the new folder to the existing window/workspace. Is there a setting to make it always open a new window? My current workaround is to first open a new window and then open the folder from that window. NBD, but a little tedious.

QUESTION
I'm making an array of sums of random choices from a negative binomial distribution (nbd), with each sum being of non-regular length. Right now I implement it as follows:
...ANSWER
Answered 2021-Nov-19 at 02:19The distribution of the sum of m samples from the negative binomial distribution with parameters (n, p) is the negative binomial distribution with parameters (m*n, p). So instead of summing random selections from a large, precomputed sample of negative_binomial(1, 0.5), you can generate your result directly with negative_binomial(gmc, 0.5):

Getting 'NoneType' object has no attribute 'text' error while scraping a web page using beautifulSoup.
The part of html document looks like this:
...ANSWER
Answered 2021-Nov-05 at 05:22You are getting the error because there are certain None values if you try to scrape directly.

QUESTION
The operations in my two methods are the same, but the input parameter types are different, so how can I optimize these two methods, it seems that they are not so repetitive? Because their operations are the same, but the parameter types are different, what should I do to make this code more elegant?
...ANSWER
Answered 2021-Nov-04 at 09:59You should make your students class extend from the same (abstract) base class or implement the same interface.
Using classesSince the two classes are both students you can define a common parent (lets say BaseStudent is the common parent)

QUESTION
I have about 5000 rows of data like this one above and I am trying to make a clustering algorithm to know which users belong to certain group. It will make a clusters of groups containing the users. When I tried to use sklearn library to make the clustering algorithm, unfortunately it tells me that data needs to be int or float. It can not find distance between these words. Is there way that I can still use the sklearn k-means algorithm on these string data frame to cluster user groups? The other way would be to convert groups and users to numbers and it will take a long time and I need to keep a dictionary of groups and users. If I were to do so, is there an easier way to convert the groups and users to numbers so that clustering algorithm can interpret? Thanks for your help in advance
...ANSWER
Answered 2021-Aug-18 at 01:22As I know, every algo works on numerics, or converts text to numerics, and then does it's job. Maybe you can try this.

Here is my code:
...ANSWER
Answered 2021-Aug-12 at 00:23To fix that bug the image should have 515585 bytes or more, I don't know where this number comes from, I have tested several combinations until achieve this result, if you try one single byte less it doesn't work, but more bytes works fine.
