Can constructor template cause ambiguity in the c++17 parameter deduction of class template : <p>Consider a simple example:</p>
<pre><code>template <class T>
struct foo {
template <template <class> class TT>
foo(TT<T>&&) {}
foo(foo<T>&&){}
foo() {}
};
int main() {
foo f1(foo<int>{}); //case 1.
foo<int> f2(foo<int>{}); //case 2.
}
</code></pre>
<p>Case 1. causes ambiguity in the template argument deduction of foo class in clang but not in gcc. I thought that template functions (here - constructor) have lower priority in overload resolution. Is it not the case here?</p>
<p>Error message:</p>
<pre><code>prog.cc:10:14: error: ambiguous deduction for template arguments of 'foo'
foo f1(foo<int>{}); //case 1.
^
prog.cc:4:5: note: candidate function [with T = int, TT = foo]
foo(TT<T>&&) {}
^
prog.cc:5:5: note: candidate function [with T = int]
foo(foo<T>&&){}
^
1 error generated.

Create sub arrays of an array : <p>What is the best and most resource efficient way to create sub-arrays of an array? I have an array of objects as follow:</p>
<pre><code>bigArray = [
{
id: 1,
name: "Marc",
age: 29
},
{
id: 2,
name: "Caroline",
age: 27
},
{
id: 3,
name: "John",
age: 30
}];
</code></pre>
<p>And I would like to generate 3 sub-arrays such as</p>
<ul>
<li>ids = [1, 2, 3]</li>
<li>names = ["Marc", "Caroline", "John"]</li>
<li>ages = [29, 27, 30]</li>
</ul>
<p>I have tried with nested "for" loops and experimented it with a map() method but I'm not convinced this is the cleanest way. Especially since I may have dozens of parameters for every object (i.e. "last name, city, car...)</p>

I cant seem to make .indexOf() work for my char array : I need to get a String from my second array (morsecode) but i need to know the index of the letter which i can get from my first array (morse)
These are my Arrays:
char morse[27]={' ','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};

And this is me trying to access the array and get the index of the char(these block of codes are looped):
counter=0;
char letter = words[counter];
letter = toLowerCase(letter);
int location=morse.indexOf(letter);
String code=morsecode[location];
counter++;
Every time I try to compile this error comes out:

how to implement if else functionality in Sql : i have an SQL query in which i have customer_id, User_id and name, the values will be provided from java class while calling the query.
the scenario here is if i have customer_id then i should only consider customer_id and need not consider user_id and name, if customer_id is null then i have to consider user_id and if user_id id null i have to consider name
right now this logic is implemented in java if else statement i want this logic to be moved to SQL query itself, following is the code
String query = "SELECT * FROM CUSTOMER WHERE "
if(customer!=null && customer.length!=0)
query = query+"AND CUSTOMER_ID LIKE '"+customer+"%'";
else if(user!=null && user.length!=0)
query = query+"AND USER_ID LIKE '"user+"%'";
else if(name!=0 && name.length!=0)
query = query + "AND NAME LIKE '"+name+"%'";

How to generate 10 terms of Fibonacci series in c++? : <p>In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and characterized by the fact that every number after the first two is the sum of the two preceding ones. <br>

Google Docs Viewer occasionally failing to load content in iframe : <p>I'm having an issue with the Google Docs viewer that is causing a nightmare to solve because it only happens intermittently. I'm looking for guidance on how to make the content in the iframe load everytime without issue as it should. </p>
<p>Steps to reproduce
1) This page is a basic HTML page with a h1 tag and an iframe containing a link to a PDF on the same server</p>
<p><a href="http://bit.ly/1mqbuf7" rel="noreferrer">http://bit.ly/1mqbuf7</a></p>
<p>2) When you load the page, the pdf document will load in the iframe 60% of the time. </p>
<p>3) If you hit refresh 10 or so times, at least once it will fail to appear. Google returns a 307 first (Which it also does when it works) and then returns a 204 - no content. When it works, it returns a 200, with the content you see in the viewer.</p>
<p>I'm struggling to understand why it only does this some of the time with no visible errors. This has been tested and failed on Google Chrome v 48.0.2564.103 (PC) and Internet Explorer Edge v25.10586 (PC) with the same results and frequency of failure. </p>
<p>Any guidance would be greatly appreciated. </p>

Variable assignment in C Vs scanf : I am new to C got a small problem in understanding below scanf line
printf("Enter a message to add to message queue : ");

how do I write this statement if I am getting the value from command line?
I think I would have to declare the variable as string?

<p>All the extra stuff there is because my program is also a GUI program. And then I also have a method that's supposed to write my object to a file...</p>

FileOutputStream outputStream = new FileOutputStream(FILE_NAME);
ObjectOutputStream oos = new ObjectOutputStream(outputStream);
oos.writeObject(videosList);
oos.close();
outputStream.close();

<p>This throws the same exception. How can I avoid this? I'm not sure how to modify the FIS/OIS to create the file if they don't find it.. or I suppose it would be more efficient for the FOS/OOS to do it instead?</p>

Is there a convenience constructor in C++? : <p>Is it possible for an overloaded constructor to somehow call another constructor within the class, similar to the code below?</p>
<pre><code>class A {
public:
A(std::string str) : m_str(str) {}
A(int i) { *this = std::move(A(std::to_string(i))); }
std::string m_str;
};
</code></pre>
<p>The code above works, yet I am afraid that calling this in the constructor might lead to undefined behavior.</p>
<p>If it does could you please explain why and also suggest a better alternative?</p>

Failed to demangle superclass with Cocoapods in Xcode 10.2 : <p>After moving to Xcode 10.2, when running my app I get a crash with the error <code>failed to demangle superclass of MyClass from mangled name MySuperClass</code>.</p>
<p>The crash occurs when I try to create an instance of MyClass. I am using CocoaPods 1.6.1 and have not yet upgraded to Swift 5. The class in question is defined inside a Pod, and is a subclass of a class defined a different Pod (listed as a sub dependency of the first Pod). </p>
<p>Adding to the complexity (unsure if it is related) is that the super class takes a generic, and the sub class defines a concrete type and does not take a generic. I.e.</p>
<pre><code>// Inside Pod B:
open class MySuperClass<DataType: Decodable> { ... }
// Inside Pod A:
open class MySubClass: MySuperClass<AConcreteStructConformingToCodable> { ... }
// Inside my project:
let myClass = MySubClass()
</code></pre>
<p>I have tried overriding the Pod build settings to build with and without optmisation without any change in behaviour.</p>

<p>I googled this error-message, but did not find anything. Nevertheless I guess there have been API-Updates that I am not aware of.</p>

Xcode 7 and openCV (no Swift): Core.hpp header must be compiled as C++ : <p>I have followed the <a href="http://docs.opencv.org/2.4/doc/tutorials/ios/video_processing/video_processing.html#example-video-frame-processing-project" rel="noreferrer">instructions</a> on how to install OpenCV on an iOS project. However when using Xcode 7 I had to add manually a prefix header. Doing this unfortunately did not help and I was still getting compile errors. I then read another post suggesting that is best to add manually the imports and not use prefix headers in Xcode 7, so I did.</p>
<p>Here is my code:</p>
<pre><code>#import "ViewController.h"
#import <opencv2/opencv.hpp>
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <opencv2/highgui/cap_ios.h>
//using namespace cv;
@interface ViewController ()
{
IBOutlet UIImageView* imageView;
IBOutlet UIButton* button;
}
- (IBAction)actionStart:(id)sender;
@end
</code></pre>
<p>However I still get the following errors. </p>
<p><a href="https://i.stack.imgur.com/7AN4B.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7AN4B.png" alt="enter image description here"></a>
<a href="https://i.stack.imgur.com/rqCoT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/rqCoT.png" alt="enter image description here"></a></p>
<p>When I uncomment the using namespace cv; I get the following:</p>
<p><a href="https://i.stack.imgur.com/VyUDH.png" rel="noreferrer"><img src="https://i.stack.imgur.com/VyUDH.png" alt="enter image description here"></a></p>
<p>I found some complex solutions talking about exposing headers to Swift etc.. I just want my project to work on Objective-C with Xcode 7 ... </p>

<p>Can anybody shed some light on what I'm doing wrong here? I can find plenty of C++ examples of passing one basic data type variable (int, double, etc.) by reference but I am unable to find any examples involving passing a vector of objects into one function, then into another function.</p>
<p>I'm using the compiler that ships with Visual Studio 2015 Community, with the default options chosen if that makes a difference.</p>
<p>I'm not sure what direction to go here, any assistance would be greatly appreciated.</p>

list comprehension does not return empty list : <p>I tried to find the relevant question but couldn't find so creating a new one.
My program creates a new list using list comprehension in python as per a simple if condition. </p>
<pre><code> Newone = [ temp for temp in Oldone if temp % 2 != 0 ]
</code></pre>
<p>It works fine but when in some situation it doesn't work. For example this one </p>
<pre><code> Oldone = [1]
Newone = [ temp for temp in Oldone if temp % 2 != 0 ]
</code></pre>
<p>This returns [1] but i am expecting Newone to be [] </p>

Spring Hateoas ControllerLinkBuilder adds null fields : <p>I'm following a tutorial on Spring REST and am trying to add HATEOAS links to my Controller results.</p>
<p>I have a simple User class and a CRUD controller for it.</p>
<pre><code>class User {
private int id;
private String name;
private LocalDate birthdate;
// and getters/setters
}
</code></pre>
<p>Service:</p>
<pre><code>@Component
class UserService {
private static List<User> users = new ArrayList<>();
List<User> findAll() {
return Collections.unmodifiableList(users);
}
public Optional<User> findById(int id) {
return users.stream().filter(u -> u.getId() == id).findFirst();
}
// and add and delete methods of course, but not important here
}
</code></pre>
<p>Everything works fine except in my Controller, I want to add links from the all user list to the single users:</p>
<pre><code>import static org.springframework.hateoas.mvc.ControllerLinkBuilder.linkTo;
import static org.springframework.hateoas.mvc.ControllerLinkBuilder.methodOn;
@RestController
public class UserController {
@Autowired
private UserService userService;
@GetMapping("/users")
public List<Resource<User>> getAllUsers() {
List<Resource<User>> userResources = userService.findAll().stream()
.map(u -> new Resource<>(u, linkToSingleUser(u)))
.collect(Collectors.toList());
return userResources;
}
Link linkToSingleUser(User user) {
return linkTo(methodOn(UserController.class)
.getById(user.getId()))
.withSelfRel();
}
</code></pre>
<p>so that for every User in the result list, a link to the user itself is added.</p>
<p>The link itself is created fine, but there are superfluous entries in the resulting JSON:</p>
<pre><code>[
{
"id": 1,
"name": "Adam",
"birthdate": "2018-04-02",
"links": [
{
"rel": "self",
"href": "http://localhost:8080/users/1",
"hreflang": null,
"media": null,
"title": null,
"type": null,
"deprecation": null
}
]
}
]
</code></pre>
<p>Where do the fields with null value (<code>hreflang</code>, <code>media</code> etc) come from and why are they added? Is there a way to get rid of them?</p>
<p>They do not appear when building a link to the all users list:</p>
<pre><code>@GetMapping("/users/{id}")
public Resource<User> getById(@PathVariable("id") int id) {
final User user = userService.findById(id)
.orElseThrow(() -> new UserNotFoundException(id));
Link linkToAll = linkTo(methodOn(UserController.class)
.getAllUsers())
.withRel("all-users");
return new Resource<User>(user, linkToAll);
}

How to write to a shared variable in python joblib : <p>The following code parallelizes a for-loop.</p>

numpy_array = np.zeros([nRepeat,G.number_of_nodes()]);
Parallel(n_jobs=4)(delayed(core_func)(repeat_index, G, numpy_array) for repeat_index in range(nRepeat));
print(np.mean(numpy_array));
</code></pre>
<p>As can be seen, the expected value to be printed is 2. However, when I run my code on a cluster (multi-core, shared memory), it returns 0.0. </p>
<p>I think the problem is that each worker creates its own copy of the <code>numpy_array</code> object, and the one created in the main function is not updated. How can I modify the code such that the numpy array <code>numpy_array</code> can be updated?</p>

How lookup works in Database? : <p>I'm trying to understand how lookups works in database. In database everything is on disk in file system.</p>
<p>So lets say If I query a data in table having millions of records with some filter clause, then all records will be loaded into memory first then
it looks for specific data or something else happens ? Correct ?</p>
<p>My understanding says, What ever the query we run, all database table's data gets loaded into memory and then do the operations. Is it correct ?</p>
<p>Secondly, If I'm having 8gb of data in table and 4gb ram, That will work to get data from Database ? Usually it works, but Does it search on disk ? Really ? </p>
<p>Please share your views.</p>
<p>Thanks</p>

Swift Xcode 10.1 - Tip Calculator Crashed Immediately : So I'm pretty new to Swift. I'm building a tip calculator in Swift and I found a tutorial online and modified it. It was a Swift 3 tutorial however, so I don't know how well it translates to Swift 10, but it was working until I tried added a feature that would allow me to split the bill. Now the whole app just gives me a white screen and no runtime errors.
I've tried to implement the splitting the bill feature two ways including using a switch case (currently in the code), and asking the user to input a number and neither way seemed to work.
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var billAmountField: UITextField!

@IBOutlet weak var numSplitLabel: UILabel!
@IBAction func calculateTip(_ sender: AnyObject) {
if let billAmount = Double(billAmountField.text!) {
var tipPercentage = 0.0
var split = 1.0
switch tipSelector.selectedSegmentIndex {
case 0:
tipPercentage = 0.15
case 1:
tipPercentage = 0.18
case 2:
tipPercentage = 0.20
case 3:
userTipAmountField.isUserInteractionEnabled = true
if let userTipAmount = Double(userTipAmountField.text!){
tipPercentage = userTipAmount / 100
}
default:
break
}
switch userSplitSelector.selectedSegmentIndex {
case 0:
if split >= 2 {
split -= 1
}
let splitString = String(split)
numSplitLabel.text = splitString
case 1:
split += 1
let splitString = String(split)
numSplitLabel.text = splitString
default:
break
}
let roundedBillAmount = round(100 * billAmount) / 100
let tipAmount = roundedBillAmount * tipPercentage
let roundedTipAmount = round(100*tipAmount)/100
let totalAmount = roundedBillAmount + roundedTipAmount
let totalSplitAmt = totalAmount / split
if (!billAmountField.isEditing) {
billAmountField.text = String(format: "%.2f", roundedBillAmount)
}
tipAmountField.text = String(format: "%.2f", roundedTipAmount)
totalAmountField.text = String(format: "%.2f", totalAmount)
totalSplitAmount.text = String(format: "%.2f", totalSplitAmt)
} else {
//show error

is it safe and good practice to use third party libraries for React Native UI? : <p>I am new in React Native. I am making hands on demos to learn react native.
I go through basic components and style. Facebook is not provieing all rich component for making rich UI. But many third party library like <a href="https://github.com/react-native-training/react-native-elements" rel="nofollow noreferrer">react elements</a> and <a href="https://nativebase.io/" rel="nofollow noreferrer">native base</a> provides many rich UI componants. So my concern is that is it safe to use those controls? are they can conflict with inbuilt control?</p>

What's special about 169.254.169.254 IP address for AWS? : <p>This IP seems to be running a service that <a href="http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html" rel="noreferrer">provides a lot of useful metadata</a> for my instance, but I'm wondering why <em>169.254.169.254</em>? What's special about that IP address?
And also wondering if the fact of having that IP occupied by that service I'm missing the chance to connect to a server with that IP on the internet?</p>

Java Error: <Identifier> expected Public Class : <p>I've just started learning Java, when trying to compile the below source code using "Javac" I am getting the following error:</p>
<p>"C:\Java>javac 99Bottles.java</p>
<p>99Bottles.java:1: error: expected</p>
<p>public class 99Bottles { //open Class "99Bottles"</p>
<p>Can't seem to figure out if this is a syntax error or if i'm missing something? Any advice would be greatly appreciated, thanks </p>
<pre><code> public class 99Bottles { //open Class "99Bottles"
public static void main (String[] args) { //Open main method
int Beernum = 99; //delcate intergar called "Beernum" with value of 99
String word = "bottles"; //delcare the string "word" with a value of "bottles"
System.out.println(Beernum + " " + word + "of beer on the walL"); //prints
System.out.println(Beernum + " " + word + "of beer"); //prints
System.out.println("you take one down"); //prints
System.out.println("you pass it around"); //prints
Beernum = Beernum - 1; //subtract 1 from the value of "Beernum"
if (Beernum > 0) { //Check if Beernum is greater than 0
System.out.println(Beernum + " " + "of beer on the wall"); //prints
} else { //if the if statement is not true run this
System.out.println("no more bottles of beer on the wall"); //prints
}
}

CMake 3.9 now creates "autogen" projects in Visual Studio? : <p>We're using CMake, Qt, and Visual Studio. Many of our projects are configured to run automoc, via passing <code>AUTOMOC ON</code> to <code>add_library</code>.</p>
<p>We recently updated to CMake 3.9.1, and Visual Studio now shows an additional project for every automoc'd library. For example, we now have a "Core" project and a "Core_autogen" project in our solution.</p>
<p>(this occurs in both VS2015 and VS2017, and both Qt 5.8 and 5.9.1)</p>
<p>This has a few annoying consequences:</p>
<ul>
<li>Nearly double the number of projects, adding a lot of visual clutter.</li>
<li>Automoc no longer runs when building an individual project through the UI, which can lead to subtle bugs when debugging build issues for a specific project.</li>
</ul>
<p>Does anyone know if there's a way to restore the previous CMake behavior for autogen? </p>
<p>Or barring that, some way to at least reduce the visual clutter of the autogen projects?</p>

How to profile CPU usage of a Python script? : <p>Ideally what I want is to record the CPU usage of a Python script that is executing a deep neural net <a href="https://keras.io/" rel="noreferrer">Keras</a> model. I'm looking for the CPU equivalent of <a href="https://pypi.python.org/pypi/memory_profiler" rel="noreferrer">memory_profiler</a>, which provides the memory consumption of a process.</p>
<p>I have looked at using <a href="https://github.com/giampaolo/psutil" rel="noreferrer">psutil</a> (suggested in <a href="https://stackoverflow.com/questions/44637844/cpu-usage-of-python-script">this answer</a>) which would indicate my script could contain some variant of</p>
<pre><code>p = psutil.Process(current_pid)
p.cpu_percent()
</code></pre>
<p>but the problem is the important function call I really want to capture the effect of would be the inference stage of the model</p>
<pre><code>model.predict(x_test)
</code></pre>
<p>and if I run psutil before/after this step the CPU usage recorded won't be a true reflection of the CPU usage of the process.</p>
<p>So then I was thinking could I use something like top/htop to log the CPU usage of the script to some file, capturing the fluctuating CPU usage while the process
is running, and then calculate an average (or something similar) after the fact. The issue I see with this, however, is don't I need to know the PID to utilise top,
so how can I use top to monitor the script before it is executed (and hasn't even been assigned a PID)?</p>
<p>I can see <a href="https://stackoverflow.com/questions/582336/how-can-you-profile-a-script/582337#582337">this highly-ranked answer</a> suggests
cProfile which gives the running time of functions within a script. Although this isn't exactly what I want I do notice that it returns
the total number of CPU seconds, which would at least let me compare CPU usage in that regard.</p>
