how can i declare pointer to different data types but they will occupy the same amount of space in memory : this is my code
int main()
{
char *pchar;
short *pshort;
int *pint;
long *plong;
float *pfloat;
double *pdouble;
pchar = pshort = pint = plong = pfloat = pdouble;
printf("sizeof *pchar is = %u\n",sizeof(pchar));
printf("sizeof *pshort is = %u\n",sizeof(pshort));
printf("sizeof *pint is = %u\n",sizeof(pint));
printf("sizeof *plong is = %u\n",sizeof(plong));
printf("sizeof *pfloat is = %u\n",sizeof(pfloat));
printf("sizeof *pdouble is = %u\n",sizeof(pdouble));
return 0;
}
/// i want Each of these pointer variables will point to different data types, but they will occupy the same amount of space in memory. how can i do that

Invoke function on each element of collection : <p>We have a list of cars - <code>List<Car></code></p>
<pre><code>Car{
String name;
String year;
String getName(){ return name;}
String getYear(){ return year;}
...
......
}
</code></pre>
<p>For each car in the list,we would need to call function isVintage(String carName,.....).<br>
All cars which return true for the above check need to be collected into a list.<br>
Is this possible using Streams?</p>

Communication between microservices - request data : <p>I am dealing with communication between microservices.</p>
<p>For example (<em>fictive example, just for the illustration</em>):</p>
<ul>
<li><strong>Microservice A - Store Users (getUser, etc.)</strong></li>
<li><strong>Microservice B - Store Orders (createOrder, etc.)</strong></li>
</ul>
<p>Now if I want to add new Order from the Client app, I need to know user address. So the request would be like this:</p>
<p><strong>Client -> Microservice B (createOrder for userId 5) -> Microservice A (getUser with id 5)</strong></p>
<p>The microservice B will create order with details (address) from the User Microservice.</p>
<p><strong>PROBLEM TO SOLVE:</strong> How effectively deal with communication between microservice A and microservice B, as we have to wait until the response come back?</p>
<p><strong>OPTIONS:</strong></p>
<ul>
<li>Use RestAPI,</li>
<li>Use AMQP, like RabbitMQ and deal with this issue via RPC. (<a href="https://www.rabbitmq.com/tutorials/tutorial-six-dotnet.html" rel="noreferrer">https://www.rabbitmq.com/tutorials/tutorial-six-dotnet.html</a>)</li>
</ul>
<p>I don't know <strong>what will be better for the performance</strong>. Is call faster via RabbitMQ, or RestAPI? <strong>What is the best solution for microservice architecture</strong>?</p>

How do you find a maximum value in a Swift dictionary? : <p>So, say I have a dictionary that looks like this:</p>
<pre><code>var data : [Float:Float] = [0:0,1:1,2:1.414,3:2.732,4:2,5:5.236,6:3.469,7:2.693,8:5.828,9:3.201]
</code></pre>
<p>How would I programmatically find the highest value in the dictionary? Is there a "data.max" command or something?</p>

Unable to create a constant value of type 'System.Char' : <p>I'm getting the following error trying to group and sum some values via LINQ in EF6:</p>
<blockquote>
<p>Unable to create a constant value of type 'System.Char'. Only primitive types or enumeration types are supported in this context.</p>
</blockquote>
<p>I've looked at half a dozen similar questions on StackOverflow and can't find my issue. Here's the query:</p>
<pre><code>var q = from c in _context.HoursProviderCosts
where c.PatientInsuranceCompanyName == insuranceName
&& c.HoursDate >= startDate
&& c.HoursDate <= endDate
group c by new { c.ID, c.PatientFirstName, c.PatientLastName } into g
select new Models.InsuranceCostListItem
{
PatientID = g.Key.ID,
PatientName = g.Key.PatientFirstName + ' ' + g.Key.PatientLastName,
Total = g.Sum(x => x.ProviderRate)
};
return q.ToList();
</code></pre>
<p>Is it something in my grouping (which I'm new to)? The underlying EF6 model is fine (I can expand the results view of <code>_context.HoursProviderCosts</code> and look at the data just fine).</p>
<p>Thanks</p>

Creating objects in android studio : I am having issues with creating objects of a class on android studio. I have created a few classes called Fan, Light and Device.
When i try to instantiate Fan and Light in MainActivity.java I get these errors:
- Field 'myFan' is never used
- Cannot resolve symbol 'breakDevice'
The code is shown below . I'd appreciate any solution to this problem.
Thanks
>MainActivity.java
```
public class MainActivity extends Activity

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public Light myLight = new Light();
Fan myFan = new Fan();
myFan.breakDevice();
myLight.breakDevice();
}
```
>Fan.java
```
package com.example.codealong3;
import android.util.Log;
public class Fan extends Device{
public Fan() {
setDeviceName("FAN");
}
@Override
public void breakDevice() {
Log.e(getDeviceName(), "BANG ! It's broken");
}
}
```

Xcode is running really slow : <p>I've recently tried to use Xcode 8 to make iOS apps and to test things in Swift however it is impossible to work on as doing a simple 'print("Hello World")' takes easily over a minute to process to print it to the console, I tried doing regular development as well by creating UI buttons etc. but when I try to compile it, it is too slow to work and that is with simple things. My computer is the Mid 2012 Macbook Pro Non-retina with 4GB of RAM, not a quick computer but I can program in Python without these problems. If anyone knows some solutions please tell me! Thanks.</p>

Swift function to duplicate images for thumbnail? : I'm making a photo gallery app.
I'm compressing the images
NSData *imageData = UIImageJPEGRepresentation(image,0.5)
and then want to create a duplicate (for thumbnails) that I'll compress even further
NSData *imageData = UIImageJPEGRepresentation(image,0.2)
I'm a little stuck on the middle step of how to create a duplicate, anyone know if there is a swift function for this?

Drawing a doughnut chart with columns inside to represent hourly stats in chart.js : <p>This is a chart that represents a stat per hour. This was taken from last.fm website which shows the no. of "scrobbles" (songs played) per hour.</p>

<p>Is this kind of chart possible with chart.js? I have been able to find a highcharts equivalent of what I am looking for:
<a href="https://www.highcharts.com/demo/polar-wind-rose" rel="nofollow noreferrer">Highcharts Windrose Example</a></p>

<p>Can anyone please guide me to a resource that will help me build something like this? Or if you know a better way to represent stat by hour, I am open to that as well.</p>

<p>However the latest Microsoft "What's new" <a href="https://blogs.msdn.microsoft.com/dotnet/2016/08/24/whats-new-in-csharp-7-0/" rel="noreferrer">posts</a> and <a href="https://channel9.msdn.com/Events/Connect/2016/105" rel="noreferrer">presentations</a> are showing this example:</p>
<pre><code>public void PrintStars(object o)
{
if (o is null) return; // constant pattern "null"
if (!(o is int i)) return; // type pattern "int i"
WriteLine(new string('*', i));
}
</code></pre>
<p>Which shows the pattern match <code>i</code> variable used outside the if level scope of the pattern match.</p>
<p>Is this an oversight, or has the scoping been changed from the spec?</p>

Can we print inside a function with a return in python? : I wonder if I can print a message inside a #python function that already returns a value?
would that print aprear when I call it from the main programme or I'll just get the value returned?
for exemple :
def test(x,y)
if x>y :
print('x is bigger then y')
return x
else:
print('y is bigger then x')
return y
Thanx for helping in advence

Is there an easy way to get something like Keras model.summary in Tensorflow? : <p>I have been working with Keras and really liked the <code>model.summary()</code>
It gives a good overview of the size of the different layers and especially an overview of the number of parameters the model has.</p>
<p>Is there a similar function in Tensorflow? I could find nothing on Stackoverflow or the Tensorflow API documentation.</p>

Why is there one `Atomic*` type for many primitive type instead of a generic `Atomic<T>`? : <p>Looking at <a href="https://doc.rust-lang.org/stable/std/sync/atomic/index.html" rel="noreferrer">the <code>std::sync::atomic</code> module</a>, one can see a bunch of different <code>Atomic*</code> types, like <code>AtomicU32</code>, <code>AtomicI16</code> and more. Why is that?</p>
<p>Rust has generics and – as I see it – it would be possible to add a generic <code>Atomic<T></code> where <code>T</code> is bounded by some trait defined in the module (in Java-ish naming: <code>Atomicable</code>). That trait would be implemented by the types that could be handled in an atomic fashion and users could just use <code>Atomic<u32></code> instead of <code>AtomicU32</code>.</p>
<p><strong>Why isn't there a generic <code>Atomic<T></code>? Why have a bunch of different types instead?</strong></p>

Is node js is middleware? : <p>When I have started learning nodeJs , I was consider this as a server side back end language . But then I came to know from a senior developer that NodeJs is not back end , it is middle ware . </p>
<p>I don't find any specific article for this point .. can anyone clear this . Is it only middle ware , or can be use as middle ware language with a server side language ?</p>

how to make nested list go down? :
I have a list inside another and want to have the parent list of elements aligned horizontally and the child list of elements aligned vertically below the <li>. But what happens is that the child's father <li> list is at the top with the list below and the rest <li> of the parent list are below aligned with the end of the child list.[enter image description here][1]

def b3(alpha, beta, delta):
"""define matric element b3"""
k = AgentCOne.k_bar(alpha, beta, delta)
c = AgentCOne.c_bar(alpha, beta, delta)
return -c/k
The error message I get is:
`> c = AgentCOne.c_bar(alpha, beta, delta)

Note:
def c_bar(self, alpha, beta, delta):

k = self.k_bar(alpha, beta, delta)
return k ** alpha - delta * k
So far, self takes one of my parameters s.t. delta stays empty... How can i prevent hat?

`HashMap<String,String> hashMap=new HashMap<>();
hashMap.put(new String("ABC"), "Hello");
hashMap.put("ABC", "Hello");
System.out.println(hashMap.size());`
How does the code return size as 1 with how internally this is evaluated? However if i use StringBuffer instead of String code returns value as 2.
Is it because it internally compares the value using compareTo() method?

How to debounce async validator in Angular 4 with RxJS observable? : <p>I'm using custom async validator with Angular 4 reactive forms to check if E-Mail address is already taken by calling a backend.</p>
<p>However, Angular calls the validator, which makes request to the server for every entered character. This creates an unnecessary stress on the server.</p>
<p>Is it possible to elegantly debounce async calls using RxJS observable?</p>
<pre class="lang-typescript prettyprint-override"><code>import {Observable} from 'rxjs/Observable';
import {AbstractControl, ValidationErrors} from '@angular/forms';
import {Injectable} from '@angular/core';
import {UsersRepository} from '../repositories/users.repository';
@Injectable()
export class DuplicateEmailValidator {
constructor (private usersRepository: UsersRepository) {
}
validate (control: AbstractControl): Observable<ValidationErrors> {
const email = control.value;
return this.usersRepository
.emailExists(email)
.map(result => (result ? { duplicateEmail: true } : null))
;
}
}

Many Modules using the same component causes error - Angular 2 : <p>I have a shared component called GoComponent that I want to use in 2 modules: FindPageModule and AddPageModule.</p>
<p>When I add it in the declarations of "FindPageModule" and in my "AddPageModule" I get an error:</p>
<blockquote>
<p>find:21 Error: (SystemJS) Type GoComponent is part of the declarations
of 2 modules: FindPageModule and AddPageModule! Please consider moving
GoComponent to a higher module that imports FindPageModule and
AddPageModule. You can also create a new NgModule that exports and
includes GoComponent then import that NgModule in FindPageModule and
AddPageModule.</p>
</blockquote>
<p>So I take it out of them both and add it in AppModule declarations, which does import FindPageModule and AddPageModule, and I get an error in a component called "FindFormComponent" which is in the declarations of FindPageModule and uses "GoComponent":</p>
<pre><code>zone.js:355 Unhandled Promise rejection: Template parse errors:

<p>How do I let components such as FindFormComponent that are declared in FindPageModule use GoComponent and also let components declared by AddPageModule use GoComponent?</p>

Angular2 - adding [_ngcontent-mav-x] to styles : <p>I'm setting up a basic angular app, and I'm trying to inject some css to my views. This is an example of one of my components:</p>
<pre><code>import { Component } from 'angular2/core';
import { ROUTER_PROVIDERS, ROUTER_DIRECTIVES, RouteConfig } from 'angular2/router';
import { LandingComponent } from './landing.component';
import { PortfolioComponent } from './portfolio.component';
@Component({
selector: 'portfolio-app',
templateUrl: '/app/views/template.html',
styleUrls: ['../app/styles/template.css'],
directives: [ROUTER_DIRECTIVES],
providers: [ROUTER_PROVIDERS]
})
@RouteConfig([
{ path: '/landing', name: 'Landing', component: LandingComponent, useAsDefault: true },
{ path: '/portfolio', name: 'Portfolio', component: PortfolioComponent }
])
export class AppComponent { }
</code></pre>
<p>Now the .css file is requested from my server, and when I inspect the page source, I can see it was added to the head. But something weird is happening: </p>
<pre><code><style>@media (min-width: 768px) {
.outer[_ngcontent-mav-3] {
display: table;
position: absolute;
height: 100%;
width: 100%;
}
.mainContainer[_ngcontent-mav-3] {
display: table-cell;
vertical-align: middle;
}
.appContainer[_ngcontent-mav-3] {
width: 95%;
border-radius: 50%;
}
.heightElement[_ngcontent-mav-3] {
height: 0;
padding-bottom: 100%;
}
}</style>
</code></pre>
<p>gets generated from this file:</p>
<pre><code>/* Small devices (tablets, 768px and up) */
@media (min-width: 768px) {
/* center the mainContainer */
.outer {
display: table;
position: absolute;
height: 100%;
width: 100%;
}
.mainContainer {
display: table-cell;
vertical-align: middle;
}
.appContainer {
width: 95%;
border-radius: 50%;
}
.heightElement {
height: 0;
padding-bottom: 100%;
}
}
</code></pre>
<p>Can somebody please explain where the _ngcontent-mav tag comes from, what does it stand for and how to get rid of it?</p>
<p>I think this is the reason why my style is not getting applied to my templates.</p>
<p>If you need more info about the app structure, please checkout my <a href="https://github.com/Shooshte/PortfolioV3">gitRepo</a>, or ask and I'll add the code to the question.</p>
<p>Thanks for the help.</p>

Why is my code outputting 0000000000000 as an invalid ISBN number? : <p>0000000000000 is a valid ISBN number, but my code says it's invalid.
My code takes a 13-digit number and checks if it's valid or not. </p>
<p>Each of the first 12 digits of the ISBN is alternately multiplied by 1 and 3. Then, we sum them up and divide the sum by 10, and get the reminder. If 10 minus the reminder is equal to the 13th digit, then it's valid.</p>

android WRITE_EXTERNAL_STORAGE permission runtime : <p>I have an app that saves a file in pictures directory of the internal memory of the phone.
I have this in my manifest:</p>
<pre><code><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
</code></pre>
<p>In android documentation it says that you must request for permission in execution (not installation) in devices with android 6 or later. But I have tested it in three devices:</p>
<ul>
<li>Moto E with android 7.0</li>
<li>Moto E with android 7.1</li>
<li>Huawei P8 Lite with android 6.0</li>
</ul>
<p>And it saves the file just with the permission in the manifest, without requesting it.
I would like to test the new code I have to add to handle this in a device that requires the permission in runtime, why these 3 devices don't require it?</p>

special characters in c string literals : <p>I'm writing some C code using the MySQL api to create databases, insert, update etc. I'm having a little trouble finding the cleanest/correct way to build the queries since the MySQL syntax can be tricky to put in a c string, for example, I'd like a query to look like this for readability:</p>
<pre><code> strcpy(query, "CREATE TABLE Users (
userID INT NOT NULL AUTO_INCREMENT, PRIMARY KEY (userID),
email VARCHAR(31) NOT NULL,
timeEntered TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
address VARCHAR(31) NOT NULL,
index (email))
");
</code></pre>
<p>then of course I'd be running the query with something like </p>
<pre><code> /* send SQL query */
if (mysql_query(conn, query)) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
} else { printf("table created\n"); }
</code></pre>
<p>however the compiler complains about expected ‘)’ and missing terminating " etc. Whats the best solution?</p>
