I am following the instructions (https://www.eclipse.org/che/docs/che-7/installation-guide/installing-che-on-minikube/) to install Eclipse:Che from Minikube hosted on a remote ubuntu VM box;

I got the installation done successfully,

I could access the portal from ubuntu VM console:

overhere, the 172.17.0.3 is actually the minikube IP;

How do I enable external access to https://che-che.172.17.0.3.nip.io/dashboard/?

from my reading and googling, it seems like SSH forwarding is the right way, but I am struggling to get it correct.

thanks!

I'm trying to pass the value of my columns datafield to my buttons in react-bootstrap-table2 dummyField. And I don't quite know how to do it. this is my columns datafield.

I am given an assignment where we are not allowed to use a DB or libraries but only textfile for data storage.

But it has rather complex requirements, for e.g. many validations, because of that, we need to "access the db" (i.e. read the textfile) many times.

My question is: should I create a class like this:

I have a function in the simple class (not stateful or stateless) but that function is called in the first Screen of the stateful widget, inside the function I have used Navigator.push to go to the second screen of the stateful widget.

Funtion Code

I Have a problem about my nested loop. Every time i request to show a specific data type it will show it but the problem is. it always double the output. How to i stop it? any also the Else showed too. i search all nested solution overhere but i don't see a similar code solution in my code. or any similarity answer for my code.

NOTE: Im new in Programming JAVA and this is my first Project so please be patient on me and explain everything what i did wrong and where i get this error/bug :) Thank you in advance

Here the code

I am trying to write a function to get a frequency of specific word from some text. Then use this function to calculate the frequency of selected word for each row in the data frame.

So far, what I am doing is creating a function that takes the input of a string and a pattern (i.e. str, pattern). Since grep captures all the patterns in the string, I felt length would take care of the job of capturing the frequency of the selected pattern.

Im having an hard time with material-ui Table (which I used dozen of times in my previous projects).

I am currently using @material-ui/core@3.5.1, i also tried with @3.2.0 and @3.6.0.

I am also using react@16.3.2 and react-dom@16.2.0

I have some other components (Button, TextField...) from material-ui in my project which works perfectly, however, when I try to use the SimpleTable example I have the following error:

I tried to used it in a brand new project => It works.

That's why I tried to switch from a version to an other but it's still not working. I cannot figured out where is my mistake :(.

Here is the my SimpleTable Component (perfect copy/past from mui documentation):

I am trying to get the value of the flashdata and userdata from one function to another within the same controller. It seems that I am using redirect in the func A to func B. So when the func loads it does not read the value and becomes Null. I used var_dump() and print_r but the values are null. Please find my sample code as follow:-

Controller: Sample.php

i have declared the session lib at the start

Using Selenium and Cucumber, I'm trying to setup a method to store WebElements through args. Then with a second method, I'm trying to check the visibility of all elements on the list.
