Firestore schema versioning and backward compatibility with android app to prevent crashes : <p>Firestore a NOSQL is a Document oriented database. Now how to manage versioning of the data as I use it with Firebase SDK and Android applications?</p>
<p>For e.g. let's say I have a JSON schema that I launch with my 1.0.0version of my android app. Later 1.0.1 comes up where I have to add some extra fields for the newer documents. Since I changed the structure to have additional information, it only applies to new documents.</p>
<p>Therefore, using this logic, I can see my Android application must be able to deal with all versions of JSON tree if used against this project I create in the firebase console with Firestore. But this can be very painful right, that I have carry the deadweight of backward compatibility endlessly? Is there a way to have some sort of version like in protobuf or something the android app can send to firestore server side so that automatically we can do something to prevent crashes on the android app when it sees new fields? </p>
<p>See also this thread, the kind of problem the engineer has posted. You can end up with this kind of problem as new fields get discovered in your JSON tree by the android app
<a href="https://stackoverflow.com/questions/49235874/add-new-field-or-change-the-structure-on-all-firestore-documents">Add new field or change the structure on all Firestore documents</a></p>
<p>Any suggestions for how we should go about this?</p>
<p>In node.js architecture we handle this with default-> v1.1/update or
default-> v1.0/update, that way we can manage the routes.</p>
<p>But for android+firebase SKD-> talking to Firestore NOSQL, how do I manage the versioning of the json schema. </p>

Inserting data in a singly link list by specifying the nth node position. : So the logic goes like this:
Suppose the link list consists of (6,7,8) as data and I pass insert(1,5),so the list will be as (5,6,7,8).
Similarly on insert(3,2) link list is (6,7,2,8).
I tried compiling the below code but it gives me an error stating-Undefined reference to main by '-start'.I tried debugging,even searching for answers but found no help.Kindly suggest a solution.Any further suggestions and bug fixes shall be welcomed.

Accessing credentials in Jenkins with the Credentials Parameter plugin : <p>My Jenkins box needs to access Stash and Jira through their REST apis. For that I need to store their credentials.</p>
<p>The way I am doing is via the Credentials Parameter, which asks me for a Name, Credential type, Required, Default Value, and a Description.</p>
<p>I define a Name as CREDENTIAL_PARAMETER, in the type I set it as "Username with password", and then I pick one credential from the list in the Default Value.</p>
<p>Next in the Build section I define that a shell should be executed, which is something like</p>
<pre><code>echo $CREDENTIAL_PARAMETER
</code></pre>
<p>I was expecting to get something like "username:password" as the CREDENTIAL_PARAMETER. However, I get a hash that I think is how the username and password can be retrieved.</p>
<p>How can I get the credentials based on the hash using bash?</p>

how to update item from listview in main form to textbox in second form in wondows form aplication in c#? : I create a program for an accountant. I have buttons for add product, delete product, add quantity of products, sell product and profit(count profit from all products in list) and listview for products with columns product, quantity,
purchase price and profit. I have problem with button "add quantity of products" my idea is, when I select product in listview and than click on the button "add quantity of products" I want to open a new window (new form) and to pass all the values from selected item from listview to second form, make mathematical calculations with that values and then pass that new values to selected item in first form ie to update select item in list view. How can I resolve that?

Example of Big O of 2^n : <p>So I can picture what an algorithm is that has a complexity of n^c, just the number of nested for loops. </p>
<pre><code>for (var i = 0; i < dataset.len; i++ {
for (var j = 0; j < dataset.len; j++) {
//do stuff with i and j
}
}
</code></pre>
<p>Log is something that splits the data set in half every time, binary search does this (not entirely sure what code for this looks like). </p>
<p>But what is a simple example of an algorithm that is c^n or more specifically 2^n. Is O(2^n) based on loops through data? Or how data is split? Or something else entirely?</p>

Imagine you have a movie collection, and you want to write code that returns your review for each one. Here are the movies and your reviews: : <p>i am getting confused , how to do this task</p>
<blockquote>
<p>Imagine you have a movie collection, and you want to write code that
returns your review for each one. Here are the movies and your
reviews:</p>
<pre><code>"Toy Story 2" - "Great story. Mean prospector."
"Finding Nemo" - "Cool animation, and funny turtles."
"The Lion King" - "Great songs."
</code></pre>
<p>Write a function named getReview that takes in a movie name and
returns its review based on the information above. If given a movie
name not found just return "I don't know!". Use a structure learned in
an earlier lesson (NOT if/else statements) to write this function.</p>
</blockquote>
<pre><code>var getReview = function (movie) {
var a = ["Toy Story 2","Finding Nemo","The Lion King"]
for(a[0]="Toy Story 2"){console.log("Great story. Mean prospector.")}

Find one or create with Mongoose : <p>I have </p>
<pre><code>Page.findById(pageId).then(page => {

<pre><code>Page.findOne({}).then(page => {
const pageId = page.id;
..
});
</code></pre>
<p>but if no page is found, it should create a new page and use this, which is done with</p>
<pre><code>Page.create({}).then(page => {
const pageId = page.id;
..
});
</code></pre>
<p>But how do I combine all this to as few lines as possible?</p>
<p>I have a lot of logic going on inside</p>
<pre><code>page => { ... }
</code></pre>
<p>so I would very much like to do this smart, so I can avoid doing it like this</p>
<pre><code>if (pageId) {
Page.findById(pageId).then(page => {
const pageId = page.id;
..
});
} else {
Page.findOne({}).then(page => {

const pageId = page.id;
..
} else {
Page.create({}).then(page => {
const pageId = page.id;
..

self.findOne(condition).then(callback).catch((err, result) => {
self.create(doc).then(callback);

quadratic equation roots c function : The problem(C programming)
================================
Write a function that calculates the real and imaginary roots of the quadratic equation
ax^2 +bx+c = 0. You should handle the three types of roots.
Hint: use this function prototype:
πππ ππππππππππΉππππ(πππ π, πππ π, πππ π, πππππ β πππππ, πππππ β πππππ)
================================
my questions:
* how can a function solving quadratic equation returns an int??
I am clueless on what that means
** I changed the fuction return type to *void()* but I couldn't handle the 2 imaginary roots not sure how to return real+imag****i***
================================
here 's what I reached so far
================================
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int calculateRoots(int a,int b,int c,float* root1,float* root2);
int main()
{
float r1,r2;
int a,b,c;
printf("enter the coefficients :\n");
scanf("%d%d%d",&a,&b,&c);
printf("roots of equation are:%d and %d",calculateRoots(a,b,c,&r1,&r2));
return 0;
}
void calculateRoots(int a,int b,int c,float* root1,float* root2)
{ float x=b*b-4*a*c;
if(x==0)
{
*root1=(-1*b)/(2*a);
*root2=(-1*b)/(2*a);
}
else if(x>0)
{
*root1=(-1*b+x)/(2*a) ;
*root2=(-1*b-x)/(2*a) ;
}
if(x<0)
{
root1=// Any help here
}
}

Need help for converting an integer to binary : <p>Im new to C++ and I need to make a program that can convert a decimal number into a binary one. This is what ive got so far, but it only shows 0000 0000 0000 0000 (the spaces are intended)</p>
<pre><code>#include <stdio.h>
#include <iostream>
#include <windows.h>
#include <math.h>
float EntierAConvertir;
int main()
{
printf("Entrez l'entier Γ convertir\n");
scanf("%lf", &EntierAConvertir);
for(long double i = 16; i != 0; i-- )
{
if (EntierAConvertir > (pow(2,i-1)))
{
printf("1");
}
else if (EntierAConvertir < (pow(2,i-1)))
{
printf("0");
}
if (i == 13 | i==9 | i == 5)
{
printf(" ");
}
}
system("pause");
return 0;
}
</code></pre>
<p>Help is very appreciated! :)</p>
