36,649,795 | Is it possible to import an HTML file as a string with TypeScript? | <p>I wonder if it is possible to do as the title said.</p>
<p>For example let's say we are working on a Angular2 project and we want to avoid set the template as an external url in order to have less http requests. Still we don't want to write all the HTML within the component because maybe it's big enough or we want designers to work in different files than devs.</p>
<p>So here is a first solution:</p>
<p>File <strong><em>template.html.ts</em></strong>
Transform a file to .ts to something like this:</p>
<pre><code>export const htmlTemplate = `
<h1>My Html</h1>
`;
</code></pre>
<p>Then in my component I can import it like this:</p>
<pre><code>import { Component } from 'angular2/core';
import {RouteParams, RouterLink} from 'angular2/router';
import {htmlTemplate} from './template.html';
@Component({
selector: 'home',
directives: [RouterLink],
template: htmlTemplate,
})
</code></pre>
<p>Actually this works perfectly but you are loosing the IDE HTML intelligence so this is bad for the designer/dev that creates the HTML templates.</p>
<p>What I'm trying to achieve is to find a way to import <strong><em>.html</em></strong> files and not .ts.</p>
<p><strong>So is it possible to import an .html file as a string in TypeScript?</strong></p>

This seems to go <em>counter</em> to the philosophy of microservices, where you want complete dependency isolation between your services. While you can manually follow this pattern, the more common practice is to enforce it by making each service it's own repository and solution/project.</p>
<p>How do you manage and deploy service fabric services, and enforce service contracts (ServiceInferfaces) using multiple solutions (in multiple Git repositories)?</p>
<p>E.g.</p>
<pre><code>Service Fabric Solution
App1 - Customers
- Service1 [Carts] From Other Solution
- Service2 [LocationInfo]From Other Solution
- Service3 [REST WebAPI for Admin] From Other Solution
App2 - Products
- Service4 [Status]From Other Solution
- Service5 [Firmware]From Other Solution
- Service6 [Event Stream] From Other Solution
External Solution
- Service1
External Solution
- Service2
External Solution
- Service3
External Solution
- Service4
External Solution
- Service5
External Solution
- Service6
</code></pre>
<p>1) As a developer, I want to check out and build all the current versions of apps/services. I want to fire up my Service Fabric project that manages all the manifests, and deploy it to my local dev cluster. I want to enforce the same service interfaces between solutions. I don't understand how you'd do this, because the application is external to the services. </p>
<p>2) As a DevOps team, I want to automate pulling down the apps, building them and deploying to Azure. </p>
<p>How do we "enforce" isolation via separate solutions, but make it easy to pull them together and deploy into the cluster, while also making it easy to make pipelines to deploy each cluster configured uniquely for DEV, QA, and PROD environments. </p>
<p>What is the workflow/process/project structure to enable this? Is it even possible?</p>

36,658,991 | Enumerate Dictionary.Values vs Dictionary itself | <p>I was exploring the sources of ASP.NET core on GitHub to see what kind of tricks the ASP.NET team used to speed up the framework. I saw something that intrigued me. In the source code of the <a href="https://github.com/aspnet/DependencyInjection/blob/dev/src/Microsoft.Extensions.DependencyInjection/ServiceProvider.cs" rel="noreferrer">ServiceProvider</a>, in the Dispose implementation, they enumerate a dictionary, and they put a comment to indicate a performance trick :</p>
<pre><code>private readonly Dictionary<IService, object> _resolvedServices = new Dictionary<IService, object>();
// Code removed for brevity
public void Dispose()
{
// Code removed for brevity
// PERF: We've enumerating the dictionary so that we don't allocate to enumerate.
// .Values allocates a KeyCollection on the heap, enumerating the dictionary allocates
// a struct enumerator
foreach (var entry in _resolvedServices)
{
(entry.Value as IDisposable)?.Dispose();
}
_resolvedServices.Clear();
}
</code></pre>
<p>What is the difference if the dictionary is enumerated like that ?</p>
<p></p>
<pre><code>foreach (var entry in _resolvedServices.Values)
{
(entry as IDisposable)?.Dispose();

<p>It has a performance impact ? Or it's because allocate a <a href="https://msdn.microsoft.com/en-us/library/x8bctb9c(v=vs.110).aspx" rel="noreferrer">ValueCollection</a> will consume more memory ?</p>

36,663,645 | Finding the minimum and maximum value within a Metal texture | <p>I have a <code>MTLTexture</code> containing 16bit unsigned integers (<code>MTLPixelFormatR16Uint</code>). The values range from about 7000 to 20000, with 0 being used as a 'nodata' value, which is why it is skipped in the code below. I'd like to find the minimum and maximum values so I can rescale these values between 0-255. Ultimately I'll be looking to base the minimum and maximum values on a histogram of the data (it has some outliers), but for now I'm stuck on simply extracting the min/max.</p>
<p><em>I can read the data from the GPU to CPU and pull the min/max values out but would prefer to perform this task on the GPU.</em></p>
<p><strong>First attempt</strong></p>
<p>The command encoder is dispatched with 16x16 threads per thread group, the number of thread groups is based on the texture size (eg; width = textureWidth / 16, height = textureHeight / 16).</p>
<pre><code>typedef struct {
atomic_uint min;
atomic_uint max;
} BandMinMax;
kernel void minMax(texture2d<ushort, access::read> band1 [[texture(0)]],
device BandMinMax &out [[buffer(0)]],
uint2 gid [[thread_position_in_grid]])
{
ushort value = band1.read(gid).r;
if (value != 0) {
uint currentMin = atomic_load_explicit(&out.min, memory_order_relaxed);
uint currentMax = atomic_load_explicit(&out.max, memory_order_relaxed);
if (value > currentMax) {
atomic_store_explicit(&out.max, value, memory_order_relaxed);
}
if (value < currentMin) {
atomic_store_explicit(&out.min, value, memory_order_relaxed);
}
}
}
</code></pre>
<p>From this I get a minimum and maximum value, but for the same dataset the min and max will often return different values. Fairly certain this is the min and max from a single thread when there are multiple threads running.</p>
<p><strong>Second attempt</strong></p>
<p>Building on the previous attempt, this time I'm storing the individual min/max values from each thread, all 256 (16x16).</p>
<pre><code>kernel void minMax(texture2d<ushort, access::read> band1 [[texture(0)]],
device BandMinMax *out [[buffer(0)]],
uint2 gid [[thread_position_in_grid]],
uint tid [[ thread_index_in_threadgroup ]])
{
ushort value = band1.read(gid).r;
if (value != 0) {
uint currentMin = atomic_load_explicit(&out[tid].min, memory_order_relaxed);
uint currentMax = atomic_load_explicit(&out[tid].max, memory_order_relaxed);
if (value > currentMax) {
atomic_store_explicit(&out[tid].max, value, memory_order_relaxed);
}
if (value < currentMin) {
atomic_store_explicit(&out[tid].min, value, memory_order_relaxed);
}
}
}
</code></pre>
<p>This returns an array containing 256 sets of min/max values. From these I guess I could find the lowest of the minimum values, but this seems like a poor approach. Would appreciate a pointer in the right direction, thanks!</p>

36,668,550 | unqualified-id error before ')' token | <p>I am new to stack overflow and I would appreciate feedback. I am creating a template graph class and have split it into two files graph.h and graph.hpp, but everytime I compile I get this error:</p>
<pre><code> In file included from graph.h:97:0,
from main.cpp:2:
graph.hpp:4:26: error: expected unqualified-id before ‘)’ token
typename graph<T>::graph(){
^
makefile:2: recipe for target 'executable.x' failed
</code></pre>
<p>Here is my graph.hpp file so far:</p>
<pre><code>#include "graph.h"
//template <typename T>
typename graph<T>::graph(){
numVertices = 0;
graphWeight = 0;
}
</code></pre>
<p>And my graph.h file looks something like:</p>
<pre><code>template <typename T>
class graph{
public:
graph();
.
.
.
private:
};
</code></pre>
<p>Also, my main.cpp is just simply:</p>
<pre><code>#include "graph.h"
int main(){
graph<int> g;
}
</code></pre>
<p>What could possibly be wrong? I know it's probably something simple that has to do with the template.</p>

36,672,514 | Efficiently merge two objects in python | <p>I have a two objects that I want to merge in such a way that all references to the two merged objects now point to the one merged object.</p>
<pre><code>#What I want
listOfObjects=[obj1, obj1, obj2, obj2, obj3]
mergeObjects(obj1, obj2)
#now
listofObjects==[merged, merged, merged, merged, obj3]
</code></pre>
<p>One way to accomplish it is this:</p>
<pre><code>def mergeObjects(obj1, obj2):
obj1.property1+=obj2.property1
obj1.property2+=obj2.property2
obj2=obj1
</code></pre>
<p>However, this has the downside that rather than having one merged object, I have a merged object and an identical copy of it. My program will merge dozens of objects with each other, so this will consume far too much memory.</p>
<p>Another way is:</p>
<pre><code>listOfObjects=[obj1, obj1, obj2, obj2, obj3]
mergeObjects(obj1, obj2)
for i in range(len(listOfObjects)):
if (listOfObjects[i]==obj2):
listOfObjects[i]==obj1
#now
listofObjects==[merged, merged, merged, merged, obj3]
#and obj2 is now free to be garbage collected
</code></pre>
<p>However, there are multiple references to these objects and iterating over every one of them each time I merge an object is also not optimal.</p>
<p>One thing I thought of is if I could use pointers. I could instead store a list of pointers to objects and then write:</p>
<pre><code>def mergeObjects(obj1_pointer, obj2_pointer):
obj1=&obj1_pointer
obj2=&obj2_pointer
obj1.property1+=obj2.property1
obj1.property2+=obj2.property2
obj2_pointer=obj1_pointer
#let's say the pointers are themselves objects so now we have:
listOfPointers==[obj1_pointer, obj1_pointer, obj1_pointer, obj1_pointer, obj3_pointer]
#obj1_pointer is now pointing to the merged object
#obj2 now has no references so is free to be deleted
</code></pre>
<p>Where I'm using & as the dereference operator.</p>
<p>So would writing my own pseudopointer object with a dereference method that returned an object be an efficient solution?</p>
<p>If not is there a cleaner way to do this (change object 1 to merged object, then have all references to object 2 instead be a reference to object 1)?</p>

36,675,251 | How to properly implement linkedIn login ? | <p>I have an andorid app and i am trying to implement linkedIn login in it.
LinkedIn SDK has been successfully integrated and i am getting user information as well along with the email address. </p>
<p><strong>Here is how my application works for google login :</strong> </p>
<p>1) get access token on mobile </p>
<p>2) send email address with access token to server </p>
<p>3) fetch details of users with access token i received via webapi of google. </p>
<p>4) if the response email matches with the email received from mobile device then check for account exists or not of that email address . If not create account and login other wise login. </p>
<hr>
<p><strong>Problem with linkedIn :</strong> </p>
<p>The access token i have received belongs to mobile sdk and i cannot use the same token to make REST API request. (<a href="https://developer.linkedin.com/docs/android-sdk-auth" rel="noreferrer">as per documentation</a>)</p>
<blockquote>
<p>Mobile vs. server-side access tokens</p>
<p>It is important to note that access tokens that are acquired via the
Mobile SDK are only useable with the Mobile SDK, and cannot be used to
make server-side REST API calls.</p>
<p>Similarly, access tokens that you already have stored from your users
that authenticated using a server-side REST API call will not work
with the Mobile SDK.</p>
</blockquote>
<p>So how to verify details in step 3) i mentioned above on my webserver ?</p>
<hr>
<p><strong>Is It a disaster ?</strong>
I am sure there has to be a way to do what i am trying to do, as there are many applications which let their users login through linkedin on their mobile apps. </p>
<p><em>Because if its not possible then anyone can easily change the email address the mobile app is sending to webserver after receiving from linkedin and i can login with any email address i want by doing that.</em> </p>

36,676,017 | JAX-RS 2 print JSON request | <p>I'd like to be able to print JAX-RS 2 JSON payload from request, regardless of actual implementation on my application server.</p>
<p>I've tried suggested solutions on SO but all include binaries from actual implementation (like Jersey and similar), and I'm allowed only to use javaee-api v 7.0 in my application.</p>
<p>I've tried implementing ClientRequestFilter and ClientResponseFilter on my Client but they don't contain serialized entities.</p>
<p>Here's an example of client:</p>
<pre><code>WebTarget target = ClientBuilder.newClient().register(MyLoggingFilter.class).target("http://localhost:8080/loggingtest/resources/accounts");
Account acc = target.request().accept(MediaType.APPLICATION_JSON).get(account.Account.class);
</code></pre>
<p>And here's the implementation of MyLoggingFilter:</p>
<pre><code>@Provider
public class MyLoggingFilter implements ClientRequestFilter, ClientResponseFilter {
private static final Logger LOGGER = Logger.getLogger(MyLoggingFilter.class.getName());
@Override
public void filter(ClientRequestContext requestContext) throws IOException {
LOGGER.log(Level.SEVERE, "Request method: {0}", requestContext.getMethod());
}
@Override
public void filter(ClientRequestContext requestContext, ClientResponseContext responseContext) throws IOException {
LOGGER.log(Level.SEVERE, "Response status: {0}", responseContext.getStatus());
}

36,676,395 | How to resolve external packages with spark-shell when behind a corporate proxy? | <p>I would like to run spark-shell with a external package behind a corporate proxy. Unfortunately external packages passed via <code>--packages</code> option are not resolved.</p>
<p>E.g., when running</p>
<pre><code>bin/spark-shell --packages datastax:spark-cassandra-connector:1.5.0-s_2.10

<pre><code>describe('Logger', () => {

36,679,379 | Elixir - Call method on module by String-name | <p>I'm pretty new to Elixir and functional programming-languages in general.</p>
<p>In Elixir, I want to call one specific function on Modules, given the Module name as String.</p>
<p>I've got the following (very bad) code working, which pretty much does what I want to:</p>
<pre><code>module_name = elem(elem(Code.eval_file("module.ex", __DIR__), 0), 1)
apply(module_name, :helloWorld, [])
</code></pre>
<p>This (at least as I understand it) compiles the (already compiled) module of <code>module.ex</code> in the current directory. I'm extracting the modules name (not as a String, don't know what data-type it actually is) out of the two tuples and run the method <code>helloWorld</code> on it.</p>
<p>There are two problems with this code:</p>
<ol>
<li><p>It prints a warning like <code>redefining module Balance</code>. I certainly don't want that to happen in production.</p></li>
<li><p>AFAIK this code compiles <code>module.ex</code>. But as module.ex is already compiled and loaded, it don't want that to happen.</p></li>
</ol>
<p>I don't need to call methods on these modules by filename, the module-name would be ok too. But it does have to by dynamic, eg. entering "Book" at the command line should, after a check whether the module exists, call the function <code>Book.helloWorld</code>.</p>
<p>Thanks.</p>
