ipe | open source Pusher server implementation compatible | Continuous Deployment library

There are multiple posts that describe the performance benefit of keeping a TCP connection open, instead of closing and opening each time you need to read or write. For example:

Best practice: Keep TCP/IP connection open or close it after each transfer?

I'm communicating with an RPC based device that takes json commands. The example I have from the device vendor opens and closes a connection each time they send a command. This is what I currently do via TcpClient in a using statement, but I'd like to see if there's anyway I could improve upon what I've already done. In fact, I had attempted this when starting the project, but couldn't figure out how to do so, so closed each time out of frustration and necessity. My latest experiment using sockets because all posts indicate doing so as a necessity for lower level control:

I've developed a Java application in JDK 16, based on the dom4j library, which adds some specific XML elements as children of a particular element in a provided XML document. Some element of the input XML document, as well as some children elements of the XML element my app creates and adds in the input document, contain Greek strings as content. For example, here is one such element of the input XML file:

I am trying to get some data from an API. The problem is that the GET call could take none or some of the filters. I have tried but am not sure how/if I can create a URL with conditional filters.

I need to merge two files using some rules. The first file1 has x users and file2 has y users; in file 1, only users that have 1 at $4 are available.

It should search the 3rd column of the file, the "IPxx" (the IPxx is unique for each user and can contain spaces in xx), and compare it to the 5th column of file 2 (without the IP, xx match xx). If it finds a match it merges the two using this formula (F1 is File1; F2 is File 2):

$2(F1):$1(F1):$2(F2):$1(F2):$3(F1):yyyy/mm/dd(today's date)

I did this to find who is available on File1:

I have a device that sends data to a FTP server. In OM2M, I want to implement an IPE to access this data and send it to MN-CSE.

Currently I am fresher on oneM2M standards And as per the below reference I found the 2 alternative for this task.

1. The ftp server notifies your AE (it is constrained for us to not to make any change on FTP server configuration so we are unable to go with this approach)

2. Your AE implements the ftp server and would then be able to directly react on new data events.

Here I just want to adopt the second approach so if possible can I get any reference so that I can proceed with that as there is not such documentation available that I found on Internet. Or kindly mention if there is any other approach that best suits to oneM2M standard for this issue.

And I just want to get confirmation that if we are monitoring FTP server periodically for the incoming input file and then process them and send them to MN-CSE then whether this approach suits to oneM2M standards or not ??

OneM2M: IPE that periodically fetches device data from FTP server

I have a device that sends data to a FTP server. In oneM2M, I want to implement an IPE to access this data and send it to MN-CSE.

I am thinking of periodically (say every 5 minutes) requesting the FTP server and fetching the data to the IPE which further processes and sends this data to MN-CSE. I just wanted to confirm if the approach is fine or are there any better ways to achieve this?

Thanks in advance.

In oneM2M, I want to update the MN-CSE configurations by sending the command from IN-CSE to MN-CSE. How can I achieve this?

My Approach: I am thinking of creating an AE on MN-CSE say CONFIG-AE. Every time I want to change anything, I will create a new Content Instance inside the container of CONFIG-AE. The container will have a subscription with the CONFIG-AE resource as the notificationURL. Now when we add new content instance, the request will be redirected to the POA (point of access) of CONFIG-AE. The POA will be basically an IPE implementation which will further process the action. Is the approach correct?

I am very new to programming. Maybe I'm not thinking it right... Here is the situation:

I have an SVG Canada map (with 12 provinces, each one has an ID). I want to give each province a minimum age, and on click of each province, I want to output the age in the console.

Here is what I have so far:
