Tyson_Codes Asks: how to avoid a type error when finding the median of a list
I am working on a project to get the mean, median and mode of a list. I have it almost all down but the median function is giving me the following error: return (list[midIndex]+list[midIndex-1])/2.0 TypeError: list indices must be integers or slices, not float

`

Code:
def median(list):
   if len(list) == 0:
       return 0
   list.sort()
   midIndex = len(list)/2
   if len(list)%2 == 0:
       return (list[midIndex]+list[midIndex-1])/2
   else:
       return list[midIndex]

def mean(list):
   if len(list) == 0:
       return 0
   list.sort()
   total = 0
   for number in list:
       total += number
   return total / len(list)

def mode(list):
   numberDictionary = {}
   for digit in list:
       number = numberDictionary.get(digit, None)
       if number == None:
           numberDictionary[digit] = 1
       else:
           numberDictionary[digit] = number+1
   maxValue = max(numberDictionary.values())
   modeList = []
   for key in numberDictionary:
       if numberDictionary[key] == maxValue:
           modeList.append(key)
   return modeList

def main():
   lyst = [3, 1, 7, 1, 4, 10]
   print("List:", lyst)
   print("Mode", mode(lyst))
   print("Median:", median(lyst))
   print("Mean:", mean(lyst))
main()

`

The answer should be 3.5 but I'm in the middle of a final week all night study bender and my brain is not functioning properly. Caffeine is failing me right now and I would love if anyone could find the error for me.

Why is it okay for my .bashrc or .zshrc to be writable by my normal user?

Zach Huxford Asks: Why is it okay for my .bashrc or .zshrc to be writable by my normal user?
My user ~/.zshrc file has the following default privileges

Code:
-rw-r--r--

My understanding of user permissions is that any process spawned by my user will then have read/write permissions to this file.

In malicious hands this could probably be used to edit aliases or append a directory of the attackers choosing to the beginning of the $PATH. I'm concerned that a malicious program that I install on the user level could then trick me into somehow giving up my sudo password through this method.

Obviously I do trust most of the programs that I install to not be malicious, however, I do use npm as a package manager for my own projects which is commonly accepted to be a vector for malware due to the sheer number of dependencies each module and it's dependencies can have.

I know that running sudo npm install -g is really bad practice but is using npm as a user which has write access to your main shell configuration file almost as bad just with a few extra steps in between, or am I lacking an understanding of how user permissions/shell configuration/npm works?

If this is insecure, then have I somehow missed security good practice for handling node js projects?

SFTP user login details real-time filtering

Amal P Ramesh Asks: SFTP user login details real-time filtering
I have enabled the SFTP login log into the default logfile /var/log/syslog and tried to filter the login time of each user and insert it into the database.

But the filtering is not worked as I expected.

Sample log file:

Code:
Jun 23 15:47:03 ip-172-16-0-62 systemd[24938]: Reached target Shutdown.
Jun 23 15:47:03 ip-172-16-0-62 systemd[24938]: Starting Exit the Session..c.
Jun 23 15:47:03 ip-172-16-0-62 systemd[24938]: Received SIGRTMIN+24 from PID 24980 (kill).
Jun 23 15:47:03 ip-172-16-0-62 systemd[1]: Stopped User Manager for UID 1051.
Jun 23 15:47:03 ip-172-16-0-62 systemd[1]: Removed slice User Slice of nidasu.
Jun 23 15:47:13 ip-172-16-0-62 systemd[1]: Created slice User Slice of ftpuser1.

Jun 23 15:47:13 ip-172-16-0-62 systemd[1]: Started Session 11907571 of user ftpuser1.

Jun 23 15:47:13 ip-172-16-0-62 systemd[24987]: Reached target Paths.

Jun 23 15:47:13 ip-172-16-0-62 systemd[24987]: Reached target Sockets.
Jun 23 15:47:13 ip-172-16-0-62 systemd[24987]: Reached target Basic System.
Jun 23 15:47:13 ip-172-16-0-62 systemd[24987]: Reached target Default.
Jun 23 15:47:13 ip-172-16-0-62 systemd[24987]: Startup finished in 15ms.

Needs to filter user login messages, like:

Code:
Jun 23 15:47:13 ip-172-16-0-62 systemd[1]: Started Session 11907571 of user ftpuser1.

I need to grep it out by matching the string "Started Session 11907571 of user ftpuser1"

The session number 11907571 is a random number and usernames also differ so grepping can ignore the numbers and usernames, only need to check the string like: **"Started Session *** of user ***"

And need to parse the line and grep the date + time, and username then insert it into the MySQL database.

If there is any option to create a daemon process to run and insert the details into DB, it will help me to do the task.

get nat port forwarding IP address

gyandoo Asks: get nat port forwarding IP address
I am using an android phone that is connected to an openwrt router via usb tether

The android phone has a dynamic wan gateway on each reboot

To make things easy for me to connect to the webui of some of the apps on the android phone via the openwrt router, I created a port forwarding rule in openwrt and entered the wan ip of the android phone manually. port forwarding rule

On each reboot of the android phone, i will have to check the routes in openwrt, get the new wan ip and update the port forwarding rule, which is fine

to make things easier on my linux machine, id like to be able to use CLI to get that wan ip that i set in port forwarding i.e 192.168.1.1:32399

not that it matters, but curlftpfs ftp mounting isn't playing well with nat, all other android app webui's are working fine with the port redirect, curlftpfs requires the wan ip, it finds the wan ip in debug but skips it

thanks

Using docker does not give error with sudo but using ctr does on starting a container

Mithilesh Asks: Using docker does not give error with sudo but using ctr does on starting a container
I am starting a container using the docker run command, it works fine. However when I try to start the same container using ctr command (irrespective of whatever snapshotter I use) I get this error:

Code:
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?

The error is coming from one of the lines in the dockerfile which is prepended by sudo . Please note that I tried removing sudo but then it gives permission denied error. As per my understanding docker engine uses ctr under the hood. Then why does not working for ctr? How shall I proceed to de

Can't change TCP/IPv4 settings on windows 10

AbdelKh Asks: Can't change TCP/IPv4 settings on windows 10
As I am trying to change my wireless IPv4 or DNS IP address, everything goes well until I click OK.

The adapter window pops up this error: "An unexpected condition occurred. Not all of your requested changes in settings could be made"

Picture of the error message


Even when I restored Windows, disabled and re enabled the adapter, the problem was not solved.

Any help would be appreciated.

Edit: I fixed that by resetting Windows 10. No other solution worked for me.
