Create a copy of object, then deleted an element only from the copy, not the original : <p>How do I make <code>obj2</code> the same as <code>obj1</code> but not affected by the deletion?</p>
<p>Currently the <code>name: 42</code> entry will be deleted from both objects.</p>
<p>Is it because of hoisting - that is, the deletion occurs before <code>obj2</code> is created?</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var obj1 = {
'name': 'John',
'age': 42,
}
var obj2 = obj1
delete obj1['name']
console.log(obj1)
console.log(obj2)</code></pre>

different result when using stream and parallelStream for redusing same array of data? : I used reduce with stream and also parallelStream on the same array with same Lambda Expression and I expected the same result but the output is different. I don't Understand why!?
following is the code:
System.out.println("Reduce me...");
Integer[] arrx = {1,2,3,4};
// Reducing the Array
Arrays
.stream(arrx)
.reduce((s1, s2) -> (int)Math.pow(s1,2) + (int)Math.pow(s2,2))
.ifPresent(System.out::println);
Arrays.asList(arrx)
.parallelStream()
.reduce((s1, s2) -> (int)Math.pow(s1,2) + (int)Math.pow(s2,2))
.ifPresent(System.out::println);
and the Output is:

How to achieve behavior of setTimeout in Elm : <p>I'm writing a web game in Elm with lot of time-dependent events and I'm looking for a way to schedule an event at a specific time delay.</p>
<p>In JavaScript I used <code>setTimeout(f, timeout)</code>, which obviously worked very well, but - for various reasons - I want to avoid JavaScript code and use Elm alone. </p>
<p>I'm aware that I can <code>subscribe</code> to <code>Tick</code> at specific interval and recieve clock ticks, but this is not what I want - my delays have no reasonable common denominator (for example, two of the delays are 30ms and 500ms), and I want to avoid having to handle a lot of unnecessary ticks.</p>
<p>I also came across <code>Task</code> and <code>Process</code> - it seems that by using them I am somehow able to what I want with <code>Task.perform failHandler successHandler (Process.sleep Time.second)</code>. </p>
<p>This works, but is not very intuitive - my handlers simply ignore all possible input and send same message. Moreover, I do not expect the timeout to ever fail, so creating the failure handler feels like feeding the library, which is not what I'd expect from such an elegant language. </p>
<p>Is there something like <code>Task.delayMessage time message</code> which would do exactly what I need to (send me a copy of its message argument after specified time), or do I have to make my own wrapper for it?</p>

How to call a function on append-icon click in Vuetify.js? : <p>I need the <code>append-icon="close"</code> to call <code>@click="clearSearch()"</code></p>
<p>Right now I'm implementing it with a dedicated button:</p>
<pre><code> <v-text-field
v-model="search"
class="search"
label="search"
prepend-icon="search"
append-icon="close">
</v-text-field>
<v-btn @click="clearSearch()"></v-btn>
</code></pre>
<hr>
<ul>
<li>I've tried adding <code>append-icon-cb="clearSearch()"</code> but it doesn't work and I don't know why</li>
<li>I've also tried simply using <code>clearable</code>, it clears the input but all the elements stay "filtered". I don't know how <code>clearable</code> works but my <code>clearSearch()</code> method simply does: <code>clearSearch() {this.search = ""}</code> and it works, that's why I use the custom <strong>clear input</strong> method</li>

In while, i'm expected that in every loop it will take an another (next one) char. but switch satatement working just for once. how can i repair this? : // this code should take every char and see if its 'A' or 'T'. Then if it takes an'A' it should ignore the next 'A'characters until it takes an 'T'. it kinda like matching the 'A' and 'T' like a dna chain.
#include <stdio.h>
int main(){
int a=0,t=0,i=0; //definitions
char c;
c = getchar();
while (i<25){ //only the first 25 characters will be processed.
switch (c){
case 'A': a++;
break;
case 'T': t++;
break;
}
if (a>t+1){
c = c - 'A';
a--;

if (t>a+1){

When to use const with objects in JavaScript? : <p>I recently read about ES6 <code>const</code> keyword and I can understand its importance when having something like this:</p>
<pre><code>(function(){
const PI = 3.14;
PI = 3.15; // Uncaught TypeError: Assignment to constant variable
})();
</code></pre>
<p>So, nobody can change my <code>PI</code> variable.</p>
<p>The misunderstanding I have is that I don't understand in which situation the use of <code>const</code> with objects can make sense (other than preventing people to do <code>myObj = newValue;</code>).</p>
<pre><code>(function(){
const obj = {a:1 ,b: 2, c:3};
//obj = {x:7 , y:8, z: 9}
//This is good
//TypeError: Assignment to constant variable.
obj.a=7; obj.b=8 ; obj.c=9;
console.log(obj); //outputs: {a: 7, b: 8, c: 9}
})();
</code></pre>
<p>So when declaring an object: when should I say: Now I <strong>must</strong> declare my object with <code>const</code>?</p>

How to correctly use Vue JS watch with lodash debounce : <p>I'm using lodash to call a debounce function on a component like so:</p>

foo: "",
}
},
watch: {
searchStr: _.debounce(this.default.methods.checkSearchStr(str), 100)

methods: {
checkSearchStr(string) {
console.log(this.foo) // <-- ISSUE 1
console.log(this.$store.dispatch('someMethod',string) // <-- ISSUE 2
}
}
}
</code></pre>
<ul>
<li>Issue 1 is that my method <code>checkSearchStr</code> doesn't know about <code>foo</code></li>
<li>Issue 2 is that my store is <code>undefined</code> as well</li>
</ul>
<p>Why doesn't my method know <code>this</code> when called through <code>_.debounce</code>? And what is the correct usage?</p>

How can I compute element-wise conditionals on batches in TensorFlow? : <p>I basically have a batch of neuron activations of a layer in a tensor <code>A</code> of shape <code>[batch_size, layer_size]</code>. Let <code>B = tf.square(A)</code>. Now I want to compute the following conditional on each element in each vector in this batch: <code>if abs(e) < 1: e ← 0 else e ← B(e)</code> where <code>e</code> is the element in <code>B</code> that is at the same position as <code>e</code>. Can I somehow vectorize the entire operation with a single <code>tf.cond</code> operation?</p>

Pattern for rich error handling in gRPC : <p>What is the pattern for sending more details about errors to the client using gRPC?</p>
<p>For example, suppose I have a form for registering a user, that sends a message</p>
<pre><code>message RegisterUser {
string email = 1;
string password = 2;
}
</code></pre>
<p>where the email has to be properly formatted and unique, and the password must be at least 8 characters long.</p>
<p>If I was writing a JSON API, I'd return a 400 error with the following body:</p>
<pre><code>{
"errors": [{
"field": "email",
"message": "Email does not have proper format."
}, {
"field": "password",
"message": "Password must be at least 8 characters."
}],
}
</code></pre>
<p>and the client could provide nice error messages to the user (i.e. by highlighting the password field and specifically telling the user that there's something wrong with their input to it).</p>
<p>With gRPC is there a way to do something similar? It seems that in most client languages, an error results in an exception being thrown, with no way to grab the response.</p>
<p>For example, I'd like something like</p>
<pre><code>message ValidationError {
string field = 1;
string message = 2;
}
message RegisterUserResponse {
repeated ValidationError validation_errors = 1;
...
}
</code></pre>
<p>or similar.</p>

How to create a complex side-by-side bar chart with SE bars in R Studio : I am creating a side-by-side bar chart with Standard Error bars from a Two-way ANOVA table in R studio. The complete version of bar chart should look like this: [example bar chart][1]

mips assembly code to shift the bit programming : <p>Read in your Student ID and save it to a register, and read in the number “10010000x” as the initial
memory address. Then shift your student ID number to the right one bit at a time, and save it to
the memory address which is 4 bytes increment from the previous memory address, until your
student ID number is smaller than 1, then save your final student ID number which is NOT smaller
than 1, and save the last memory address, and how many iterations to 3 different memory
addresses. Turn in the hardcopy of the MARS graphic printout which has the MIPS Assembly
code showing your student ID, and memory addresses and all registers values, and also answer
the following three questions on the hard copy paper :<br>
(1) How many shift right you have to do to get your student ID number to be smaller than 1 ?
(2) What is your last NOT smaller than 1 binary student id number ?
(3) What is the last memory address that saves that last NOT smaller than 1 student ID ? </p>

pre-increment and post-increment in C : <p>First of all, I would like to apologize, if this question has been asked before in this forum. I searched, but could't find any similar problem.</p>
<p>I am a beginner in C. I was going through a tutorial and came across a code, the solution of which I can't understand. </p>
<p>Here is the code - </p>
<pre><code>#include <stdio.h>
#define PRODUCT(x) (x*x)
int main()
{
int i=3, j, k;
j = PRODUCT(i++);
k = PRODUCT(++i);
return 1;
}
</code></pre>
<p>I tried running the code through compiler and got the solution as "j = 12" and "k = 49". </p>
<p>I know how #define works. It replace every occurrence of PRODUCT(x) by (x*x), but what I can't grasp is how j and k got the values 12 and 49, respectively. </p>
<p>Any help would be appreciated. </p>
<p>Thank you for your time.</p>

Just Happened ... it was working fine ... issue with Android Studio 2.3.3 : Iam getting the following error...
I am new at this and hate to mess with the gradle or any file ... can anyone please help...
the errors:
"
The SDK platform tools version (25.0.6) is too old to check APIs compiled with API 26; please update
This check scans through all ANDroid API calls in the application and warns about any calls that are not available on all versionstargeted by the application (according to its minimum SDK attribute in the manifest).
If you really want to use this API and don’t need to support older devices just set the minSdkVersion in the build.gradle or AndroidManifest.xml files
If your code is deliberately accessing newer APIs and you have ensured (e.g. with conditional execution) that this code will only ever be called on a supported platform, then you can annotate you class or methodwith the @TargetApi annotation specifying the local minimum SDK to Apply, such as @TargetApi(11), such that this check considers 11 rather than you manifest file’s minimum SDK as the required API level.
If you are deliberately setting android: attributes in style definitions, make sure you place this in values-xxx folder in order to avoid running into runtime conflicts on certain devices where manufacturers have added custom attributes whose ids conflict with new ones or later platforms.
Similarly, you can use tooltargetApi=”11” in an XML file to indicate that the elements will only be inflated in an adequate context."
I also get the package name up top as an error, but i just created the new App and even though it indicates an error. it compiles and runs on the emulator on the targeted device.
Help.

How many intermediate steps should you use when programming? : <p>I am not new to programming and can solve most my daily programming problems alone, but I have a question, which will most likely be closed in a few minutes/hours. But still, I am interested in what you guys have to say about this.</p>
<p>Let's look at this simple Python code snippet for example:</p>
<pre><code>word = "cake"
loud_word = word.upper()
word_length = len(word)
print("%s -> %s, length: %s" % (word, loud_word, word_length))
</code></pre>
<p>And now look at this:</p>
<pre><code>word = "cake"
print("%s -> %s, length: %s" % (word, word.upper(), len(word)))
</code></pre>
<p>They do exactly the same thing. Which one should you use though? Avoid many variables and output directly, or not?</p>
<p>I didn't find anything regarding this in PEP0008.</p>
<p>(I know, this may be a stupid question but I am obsessed with using next to no variables right now and I want to hear your opinion.)</p>

windows form application sequential ShowDialog()s : well i have a funny problem with closing dialog forms.
here is the problem:
I run application and open second form (through menu strip) as `showdialog();` and then from second form open third form. when i open third form by `button 1` and then close it everything is alright, but when i open the third form by `button 2` and then close it, third form will be closed and then it closes the second form also. !!! in second form when i show a `messageBox` and close it also the second form will be closed.
here is my codes:
open second form from first form codes:
private void settingsToolMenu_Click(object sender, EventArgs e)
{
settingsForm s1 = new settingsForm(this);
s1.ShowDialog();
}
open third form from second by button 1 form codes:
private void addReportButton_Click(object sender, EventArgs e)
{
addReport a1 = new addReport(this);
a1.ShowDialog();
}
open third form from second by button 2 form codes:
private void editReportButton_Click(object sender, EventArgs e)
{
addReport a2 = new addReport(this);
a2.ShowDialog();
}
as you see there is no differences between `button 1` and `button 2`

How to increment the counter inside a Liquid for loop? : <p>I am struggling to figure out how to increment the index variable within a for loop in Liquid/Jekyll. Currently, I have something along the lines of </p>
<pre><code>{% for i in (0..num_posts) %}
{% if i < some_value %}
do_thing
{% else %}
{% endif %}
{% assign i = i|plus:1 %}
{% if i<some_value %}
do_another_thing
{% else %}
{% endif %}
{% endfor %}
</code></pre>
<p>The problem is, instead of incrementing i, it leaves i as the same value.</p>
<p>Things I have tried:</p>
<ol>
<li>Using <code>{% assign i = i|plus:1 %}</code>.</li>
<li>Using <code>{% increment i %}</code>. </li>
<li><p>Using</p>
<pre><code>{% assign j = i|plus:1 %}
{% assign i = j %}
</code></pre></li>
</ol>
<p>I can't use the <code>offset</code> command either since the code doesn't always check only 2 if statements in the loop. </p>
<p>Any ideas?</p>

Difference between Dense(2) and Dense(1) as the final layer of a binary classification CNN? : <p>In a CNN for binary classification of images, should the shape of output be (number of images, 1) or (number of images, 2)? Specifically, here are 2 kinds of last layer in a CNN:</p>
<pre><code>keras.layers.Dense(2, activation = 'softmax')(previousLayer)
</code></pre>
<p>or</p>
<pre><code>keras.layers.Dense(1, activation = 'softmax')(previousLayer)
</code></pre>
<p>In the first case, for every image there are 2 output values (probability of belonging to group 1 and probability of belonging to group 2). In the second case, each image has only 1 output value, which is its label (0 or 1, label=1 means it belongs to group 1).</p>
<p>Which one is correct? Is there intrinsic difference? I don't want to recognize any object in those images, just divide them into 2 groups.</p>
<p>Thanks a lot!</p>

How can I instantiate a lambda closure type in C++11/14? : <p>I'm <a href="https://stackoverflow.com/questions/55708180/lambda-closure-type-constructors">aware</a> that there's no default constructor for lambda closure type. But does that mean it's impossible to instantiate it after it being passed as a template parameter?</p>
<p>Consider the following <a href="https://ideone.com/QnPYL8" rel="noreferrer">minimal example</a>:</p>
<pre><code>#include <iostream>
template <typename FuncType>
std::pair<int,int> DoSomething() {
return FuncType()(std::make_pair(1,1));
}
int main() {
auto myLambda = [](std::pair<int,int> x) {
return std::make_pair(x.first*2,x.second*2);
};
std::pair<int,int> res = DoSomething<decltype(myLambda)>();
return 0;
}
</code></pre>
<p>For performance reasons, <a href="https://stackoverflow.com/questions/5057382/what-is-the-performance-overhead-of-stdfunction">I can't use <code>std::function</code></a> to avoid virtual pointer calls. Is there a way to do this? I need to instantiate that lambda once and use it many times inside that function. </p>
<p>How does the standard library make it work when <code>decltype(myLambda)</code> is passed to something like <code>std::map</code> comparators in the template parameter?</p>

As in the form i get value 40 i need to make the colspan on the 40th td in the clicked row.
How can i implement something like that in javascript or jquery?

<ol>
<li>UI Layer</li>
<li>BLL</li>
<li>DataModel</li>
<li>DAL</li>
</ol>
<p>Now, i want to create a asp.mvc UI within the same above solution, for the same application using MVC pattern.
When i searched about mvc solution architecture, mostly i found, the model, view and controllers are created in the same project. But, since i already have the model as DAL, and BLL which developed for my winforms application, how can i design the solution architecure so that i can make use of my present BLL, DataModel and DAL layers.</p>
<p>Or, is it better to do the mvc projects as a separate solution?
In that case, i have to maintain my BLL and DAL separately na.</p>
<p>Please advise in this regard.

A weird output ? : I am new to the C.Sc course and we are taught C program.
I was trying some of the basic stuff. Currently I am learning User-Defined-Function.
The following code is the one I was trying with. I know it is pretty simple but I am not able to understand why it is producing such weird output.
#include <stdio.h>
int add(int a); //function declaration
int main (void)
{
int b,sum;
printf("\nEnter a number: ");
scanf("%d", &b);
sum = add(b); //function calling
printf("\nSum: %d\n\n", sum);
}
int add(int a) //function definition
{
int result;
for(int i = 0; i < a; i++)
{
result = result + i;
return result;
}
}
The output for 1 is 32743
The output for 2 is 32594
The output for 3 is 32704
The weird thing is output change each time for the same number.
It's just weird considering my experience in C.Sc. till date. Kindly explain what the program is doing.
**This is the right place to post problems like this. Right ?**
