The psychology of ‘none of the above’

I am working on a design for a formal registration service that demands users categorise themselves according to a closed list of options. The list is not exhaustive, so some users don’t see an option that works for them. However, user testing shows some reluctance to hit the ‘none of the above’ option. I’m wondering if the negative precept in the ‘none of the above’ wording has been explored anywhere? Time spent hesitating over this step suggests that users are disinclined to leave the page unresolved. Can anyone point me in a useful direction? Thanks!

Issue with blinking screen above 4.20.17 kernel [CPU, GPU]

My notebook with Intel i7-7700Q and Nvidia 1050Ti have real problem with blinking/pulse of the screen during the moving cursor in the system or high performance usage (ex. code compilation).

I did not notice the issue, until I felt my eyes were bleeding and going to go out from sockets.

At the beginning I thought that the problem is with screen refreshing, but after changing the kernel using Ukuu on Ubuntu 18.04 LTS over and over again I found kernel 4.20.17. This one is good for my notebook configurations and screen acts well.

Why I am asking? Sometimes I cannot continue my work after suspending laptop, due to the poor performance. I thought newer kernels will solve the issues with poor performance and blinking screen. Will it be solved?

I tried to set conf files for nautilus or nvidia, updating the Nvidia. Noting helped. Do you encountered any similar situation?

How to install Windows 8 or above alongside a pre installed ubuntu 18.04

I have an installed Ubuntu 18.04 in my 8GB RAM Laptop. I’d like to install Windows 8 or above with it (meaning dual booting) as I am a programmer and need to use unity and visual studio. I have read places about dual booting these 2 but they say install Windows first. All my files here are very important so I don’t want to lose it and also use grub as the bootloader if it can happen.

Please help me on how to install Windows alongside an existing Ubuntu 18.04

Now the question is that which of the following technique is best for the above given scenario and why?

Suppose you are working for a software company having a system with limited memory and you have given a task. You are using recursive function to complete the task but you realize that you can use tail recursion instead of recursive function and then you realize that this tail recursion can be converted to loop. Now the question is that which of the following technique is best for the above given scenario and why? 1. Recursive Function. 2. Tail Recursion. 3. Loop

Technique is best for the above given scenario and why? [on hold]

Due to increase in the list data (above 5000) of SharePoint, we are facing performance issues in the powerapp’s project

Due to increase in the list data (above 5000) of SharePoint, we are facing performance issues in the power app’s project.

Few activities we have done to improve its performance:

1) Implemented concurrent on collects

2) Implemented cache

But performance issue is the same.

How to design a generic RestClient using jersey 2.0.0 version and above?

I want to make a RestClient class using jersey API version 2.0.0 and above, that provides methods for all kinds of HTTP methods like GET/POST/PUT/DELETE and can support all functionalities like uri-parameters, setting cookies etc.

My initial thought is to design certain overridden methods in the class which can support varying type of arguments as shown below and provide one method which aggregates all of the parameters and performs the rest call and return the Generic Response.

method 1:

public Response callServer(Map<String,Object> queryParams, String restEndpointURL){} 

method 2:

public Response callServer(Map<String,Object> queryParams, String restEndpointURL, Cookies cookies){} 

method 3:

private actualCall(Map<String,Object> queryParams, String restEndpointURL, Cookies cookies, ...){     //perform the actual call to the server by making checks on all of the parameters provided by the calling methods     } 

The issue I am facing is in structuring the design of the Class which includes -what parameters should i provide support for other than queryParams,URI params and Cookies -how to validate these arguments in the actualCall
