height of html with body and default margin on chrome | <p>As you might know, Chrome has a default body margin of <strong><code>8px</code></strong>.</p>
<p>However, this poses an issue when I keep the margin on the body and set its height to <strong><code>100%</code></strong> (along with html at <strong><code>100%</code></strong>). It takes the height of html and places it after the top margin of <strong><code>8px</code></strong>, and ends with a bottom margin of <strong><code>8px</code></strong>. However the html size doesn't adapt to the 16 pixel difference (top 8 + bottom 8). </p>
<p>I'm thinking this has to do with how the document flow works, html having its size assigned before body does, but I do not have any clue how to fix issue.</p>
<p>The only way I thought I could fix this was to do <code>calc()</code> notation on the html height attribute: <code>height: calc(100% + 16px)</code> but doesn't work. If you know why it doesn't I would like to be told.</p>
<p>code to replicate the issue:</p>
<p>CSS</p>
<pre><code>html {
height: 100%;
background: rgb(42,69,66);
background: -webkit-linear-gradient(top, rgba(73,94,8,1) 0%, rgba(145,232,66,1) 100%) no-repeat;
}
body {
height:100%;
}
.divz {
background-color: olive;
height: 100%;
}
</code></pre>
<p>HTML</p>
<pre><code><body>
<div class="divz"></div>
</body>
</code></pre>
<p><a href="https://jsfiddle.net/nd1hhz6q/" rel="nofollow">Here is a jsfiddle</a> that replicates the issue. Notice at the bottom how theres a <strong><code>16px</code></strong> spacing between the end of the page and the end of html. </p>
<p><strong>EDIT:</strong> I want the margin to stay on body.</p>
<p><strong>EDIT 2:</strong> another thing I attempted is to set the <code>min-height: 100%</code> to the <code>html</code>, which does do what I want but setting <code>min-height: 100%</code> to <code>body</code> doesn't work if it is set to html.</p> | 1 |
Host Multiple Sites on Apache with same IP and Port | <p>Trying to host multiple sites from the same Ubuntu Apache box. Same IP and Same Port. The differentiation being the host header or domain address. I could do this easy with IIS but I'd like to move to Apache.</p>
<p>Right now with this code, every time I do a test with these URL's. I get pointed to the 1st URL even if I try a different URL. (I assume because it's the 1st Port 80 website). Everything works fine locally if your on the desktop of the Ubuntu server but not if your on a local desktop or internet. (These are my lab domain names.)</p>
<p>My www.conf file that sits in /etc/apache2/sites-available. The same conf file shows in /etc/apache2/sites-enabled</p>

PHP: Copy entire contents of a directory | <p><strong>Sorry for new post!</strong> I'm not yet trusted to comment on others posts.</p>
<p>I'm having trouble copying folders and this is where I started:

Why am I getting "error: type name is not allowed" with these spaghetti templates? | <p>I have the following code with a bit of a "spaghetti" of templates:</p>
<pre><code>template <typename A, typename B, typename... Args>
class C {
/*... */
Bar& getBar() { /* ... */ }
public:
template <typename U>
static void Foo() {
A a = getA<U>();
Baz& bar = getBar();
bar.frob<U>(a); /* @@@ */
}
/*... */
}
/* no template */
class D : public C<SomeA, D, const SomeE&> { /* ... */ }
/* no template */
class F : public D { /* ... */}
</code></pre>
<p>and when I try to compile a function with the following statement:</p>
<pre><code>D::Foo<F>();
</code></pre>
<p>I get the error <code>type name is not allowed</code>, on the line marked <code>@@@</code>. Why would I be getting that? I know you get it when you try to call a function with a type name, but it doesn't look like I'm doing it here.</p> | 1 |
Fast way to determine filtered values in a Pivot Table | <p>I need to check if a host of pivot tables are correctly filtering out the right items. Right now I am scrolling down and eye-balling to see if certain entries are excluded and nothing else. But each of my fields have 10,000+ items and it's taking forever and I am worried that I might miss something. Is there some way that I can get excel to simply list the values excluded in a Pivot table?</p>

Is it possible to have two vue.js instances in different windows use the same data? | <p>I would like to be able to use two windows in my vue.js app, one for managing data, and one for presentation of the same data. (Imagine a live presentation where I can change things on the fly in one window on my laptop but my audience sees a simplified presentation of the data—ie, they don't see all the editing tools—in a separate window on a projected screen.)</p>
<p>As a prototype, I've tried implementing a basic todo app, like so:</p>
<pre><code><html>
<body id="app">
<div id="entry-form">
<input type="text" placeholder="enter a todo item" v-model="todo">
<button v-on:click="addTodo">+</button>
</div>
<div id="todo-list">
<ol>
<li v-for="t in todos">
<span>{{ t }}</span><button v-on:click="delTodo">-</button>
</li>
</ol>
</div>
<button v-on:click="openViewer">Viewer</button>
<script src="vue.min.js"></script>
<script>
var stateData = {
todo : '',
todos : [],
}
new Vue({
el: '#app',
data: stateData,
methods : {
addTodo : function() {
if ( this.todo ) {
this.todos.push(this.todo);
this.todo = '';
}
},
delTodo : function(index) {
this.todos.splice(index,1);
},
openViewer : function() {
var w = window.open("viewer.html", "viewer");
w.getStateData = function() {
return stateData;
}
}
},
});
</script>
</body>
</html>
</code></pre>
<p>And then a viewer.html (that is opened by the openViewer function in the above file) like so:</p>
<pre><code><html>
<body id="viewer">
<div id="todo-list">
<ol>
<li v-for="t in todos">
<span>{{ t }}</span>
</li>
</ol>
</div>
<script src="vue.min.js"></script>
<script>
window.onload = function() {
new Vue({ el: "#viewer", data: getStateData() });
}
</script>
</body>
</html>
</code></pre>
<p>This seems to get me half-way there. I can enter a few todos and click on the Viewer button, and a second window opens up showing the todos as expected. However, when I start entering new todos after opening the viewer window things start behaving strangely. The input fields get cleared upon blur, and the todo list no longer appears in the main window but it still works in the viewer window.</p>
<p>Obviously I'm abusing something about the way vue.js is intended to work. Is what I'm trying to achieve possible with vue.js? If so, please inform me how this would be done in the vue.js way?</p>
<p>Thanks</p> | 1 |

Block IP from accessing Google Compute Engine instance | <p>I'm trying to block a certain IP address or range to reach my WordPress server that's configured on my Google Compute Engine server.</p>
<p>I know I can block it via Apache, but even if I do my access_logs will still be filled with 403 error from requests from this IP.</p>
<p>Is there any way to block the IP entirely and don't even let it reach Apache?</p>

AttributeError: 'module' object has no attribute 'cm' | <p>I'm using Python2.7. This is a function from Udacity's Intro to Machine Learning course. When the function is called, a plot is shown. However, there are suppose to be colored regions shown too, and they are not shown.</p>
<p>When I run the script which calls this function, the figure opens. When I close the figure, I see this message:</p>
<pre><code>Traceback (most recent call last):
File "your_algorithm.py", line 45, in <module>
prettyPicture(clf, features_test, labels_test)
File "e:\Projects\Udacity\Intro to Machine Learning\ud120-projects\choose_your_own\class_vis.py", line 22, in prettyPicture
plt.pcolormesh(xx, yy, Z, cmap=pl.cm.seismic)
AttributeError: 'module' object has no attribute 'cm'
</code></pre>
<p>It seemed to me like <code>cm</code> is an attribute of <code>matplotlib</code> from <a href="http://matplotlib.org/api/cm_api.html" rel="noreferrer">matplotlib cm</a>. Thus, I changed <code>pl</code> to 'plt`. This gets rid of the error message, but the colored regions still do not show up in plot. Thus, I'm less convinced this is correct.</p>
<p>Why are the colored regions not showing up?</p>
<p>Here is the code for the function prettyPicture:</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
import pylab as pl
def prettyPicture(clf, X_test, y_test):
x_min = 0.0; x_max = 1.0
y_min = 0.0; y_max = 1.0
# Plot the decision boundary. For that, we will assign a color to each
# point in the mesh [x_min, m_max]x[y_min, y_max].
h = .01 # step size in the mesh
xx, yy = np.meshgrid(np.arange(x_min, x_max, h), np.arange(y_min, y_max, h))
Z = clf.predict(np.c_[xx.ravel(), yy.ravel()])
# Put the result into a color plot
Z = Z.reshape(xx.shape)
plt.xlim(xx.min(), xx.max())
plt.ylim(yy.min(), yy.max())
plt.pcolormesh(xx, yy, Z, cmap=pl.cm.seismic)
# Plot also the test points
grade_sig = [X_test[ii][0] for ii in range(0, len(X_test)) if y_test[ii]==0]
bumpy_sig = [X_test[ii][1] for ii in range(0, len(X_test)) if y_test[ii]==0]
grade_bkg = [X_test[ii][0] for ii in range(0, len(X_test)) if y_test[ii]==1]
bumpy_bkg = [X_test[ii][1] for ii in range(0, len(X_test)) if y_test[ii]==1]
plt.scatter(grade_sig, bumpy_sig, color = "b", label="fast")
plt.scatter(grade_bkg, bumpy_bkg, color = "r", label="slow")
plt.legend()
plt.xlabel("bumpiness")
plt.ylabel("grade")

How can I implement comparable interface in go? | <p>I've recently started studying Go and faced next issue. I want to implement Comparable interface. I have next code:</p>
<pre><code>type Comparable interface {
compare(Comparable) int
}
type T struct {
value int
}
func (item T) compare(other T) int {
if item.value < other.value {
return -1
} else if item.value == other.value {
return 0
}
return 1
}
func doComparison(c1, c2 Comparable) {
fmt.Println(c1.compare(c2))
}
func main() {
doComparison(T{1}, T{2})
}
</code></pre>
<p>So I'm getting error</p>
<pre><code>cannot use T literal (type T) as type Comparable in argument to doComparison:
T does not implement Comparable (wrong type for compare method)
have compare(T) int
want compare(Comparable) int
</code></pre>
<p>And I guess I understand the problem that <code>T</code> doesn't implement <code>Comparable</code> because compare method take as a parameter <code>T</code> but not <code>Comparable</code>.</p>
<p>Maybe I missed something or didn't understand but is it possible to do such thing?</p> | 1 |
Check if SQL server service is running | <p>Currently we are facing a problem that effects system stability, our server has SQL server 2012 and for unknown reason its services stop running and that needs someone to restart it manually every single day. I have created a command in batch file to restart SQL server automatically and it works fine, however, I am looking for better command that can check if SQL server stop, just restart it, if running, just ignore. How can I do that command that ?</p>

How do I switch between active docker-machines on OSX? | <p>Within MacOS, I have created 2 docker machines, say, dev1 and dev2.
In one terminal running <code>$docker-machine active</code> shows dev1 as an active docker-machine and in the other, dev2. Now I want to switch to dev2 in the 1st terminal (without stopping/removing etc. dev1) so that I'll have dev2 in both. </p>

What is the Rails way to work with polymorphic associations? | <p>I have few models in my Rails application, which are:</p>
<ol>
<li>User</li>
<li>Photo</li>
<li>Album</li>
<li>Comment</li>
</ol>
<p>I need to make comments belog to either to <code>Photo</code> or <code>Album</code>, and obviously always belong to <code>User</code>. I'm going to use <a href="http://guides.rubyonrails.org/association_basics.html#polymorphic-associations" rel="noreferrer">polymorphic associations</a> for that.</p>
<pre><code># models/comment.rb
class Comment < ActiveRecord::Base
belongs_to :user
belongs_to :commentable, :polymorphic => true
end
</code></pre>
<p>The question is, what is the Rails way to describe <code>#create</code> action for the new comment. I see two options for that.</p>
<p><strong>1. Describe the comment creation in each controller</strong></p>
<p>But ths is not a DRY solution. I can make one common partial view for displaying and creating comments but I will have to repeat myself writing comments logic for each controller. So It doesn't work</p>
<p><strong>2. Create new CommentsController</strong></p>
<p>This is the right way I guess, but as I aware:</p>
<blockquote>
<p>To make this work, you need to declare both a foreign key column and a
type column in the model that declares the polymorphic interface</p>
</blockquote>
<p>Like this:</p>
<pre><code># schema.rb
create_table "comments", force: :cascade do |t|
t.text "body"
t.integer "user_id"
t.integer "commentable_id"
t.string "commentable_type"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
</code></pre>
<p>So, when I will be writing pretty simple controller, which will be accepting requests from the remote form:</p>
<pre><code># controllers/comments_controller.rb
class CommentsController < ApplicationController
def new
@comment = Comment.new
end
def create
@commentable = ??? # How do I get commentable id and type?
if @comment.save(comment_params)
respond_to do |format|
format.js {render js: nil, status: :ok}
end
end
end
private
def comment_params
defaults = {:user_id => current_user.id,
:commentable_id => @commentable.id,
:commentable_type => @commentable.type}
params.require(:comment).permit(:body, :user_id, :commentable_id,
:commentable_type).merge(defaults)
end
end
</code></pre>
<p>How will I get <code>commentable_id</code> and <code>commetable_type</code>? I guess, <code>commentable_type</code> might be a model name.</p>
<p>Also, what is the best way to make a <code>form_for @comment</code> from other views? </p> | 1 |
Catching EJBTransactionRolledbackException | <p>I have problem with understanding the EJBTransactionRolledbackException.</p>
<p>I have entity:</p>
<pre><code>@Entity
public class MyEntity {
@Id
@GeneratedValue
private Long id;
@Size(max=5)
private String name;
//...
}
</code></pre>
<p>and repository which is SLSB because of ease of CMT:</p>
<pre><code>@Stateless
public class ExampleRepository {
@PersistenceContext
private EntityManager em;
public void add(MyEntity me) {
em.persist(me);
}
}
</code></pre>
<p>now I have test Servlet, when I simulate ConstraintViolation (too long name).</p>
<pre><code>@WebServlet("/example")
public class ExampleServlet extends HttpServlet {
@Inject
private ExampleRepository repo;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
MyEntity me = new MyEntity();
me.setName("TooLongName");
try {
repo.add(me);
} catch(EJBTransactionRolledbackException e) {
System.out.println("Exception caught");
}
}
}
</code></pre>
<p>I know that in such scenario EJB container will wrap the ConstraintViolationException so I catch the EJBTransactionRolledbackException instead. The problem is that in the console I can see my message from catch block ("Exception caught") but before that there are tons of exception logs produced (<a href="http://pastebin.com/BBT66RyB" rel="nofollow">link</a>).
I don't quite understand what happened - is this exception caught or not? How to prevent all these error messages in the console in such simple scenario?</p> | 1 |
Add content in bounce margin of ScrollView in React Native? | <p>In my app I'm using <code><ScrollView /></code> to view pages of a book scrolling horizontally. When a user gets to the end of the <code><ScrollView /></code> there is a bounce that shows a white area to the right that is only visible if the user drags the last page to the left.

Codeigniter retrieve top 5 most occurring rows in column | <p>I currently am using codeigniter 3 to build a website. I have been able to build a full gallery and cart system using the database and active record. As well as a backend. I am currently now working the charts.js to build a pie graph in the backend of the 5 top sellers on the site. As well I will be making a graph for items sold by hour using the line graph. I can make the charts appear with dummy data no problem, however I am running into an issue of trying to retrieve the right data from the DB. It appears the query is going to be quite complex. </p>
<p>My mysql table is named <code>order_items</code>. And in order items there is a column <code>qty</code> and a column <code>product_type</code>. Both return integers. What I need is to find which five items have sold the most quantity. Eventually I will need to add the data to my charts.js setup as follows. Anyone with advanced experience with codeigniter active record?</p>
<pre><code>var pieData = [{
value : 300,
color : "#F7464A",
highlight : "#FF5A5E",

Laravel ResetsPasswords Trait | <p>Locally, I have updated this trait to do some different redirecting after the user submits the getEmail() method to request the reset password link. When pushed to production, my editions aren't there. I'm guessing this is because the ResetsPasswords trait is in the laravel framework which is installed separately from my repository on the server.</p>
<p>If this is the case, what's the best way to change how this ResetsPasswords trait functions. Do I make my own and include that in the repository and just change my controller? Below is the PasswordController.</p>
<p>Thanks!</p>
<pre><code><?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ResetsPasswords;
class PasswordController extends Controller
{
/*
|--------------------------------------------------------------------------
| Password Reset Controller
|--------------------------------------------------------------------------
|
| This controller is responsible for handling password reset requests
| and uses a simple trait to include this behavior. You're free to
| explore this trait and override any methods you wish to tweak.
|
*/
use ResetsPasswords;
protected $redirectPath = '/main';
/**
* Create a new password controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('guest');
}
}
</code></pre>
<p>Update: So, in the ResetsPasswords trait, I modify the redirect getSendResetLinkEmailSuccessResponse() method. So, do I instead just put that method in my controller (with the same name) and my edited code?</p>
<pre><code>protected function getSendResetLinkEmailSuccessResponse($response)
{
...modified code...
}

AngularJS adding a new item and removing an existing item from a list | <p>(1) I am trying to add a new user to a list of items (userList). The functionality works, but there is an issue. I made the list 'selectable' aka.. when a user clicks on an item on the list the textboxes in my html5 code gets populated w/ values from the selected item in the list. This allows the user to edit the individual properties from the item. Right underneath the group of textboxes is my 'add new user' button..... When the app first runs, the textboxes are empty and I fill them w/ appropriate text and click the add button and the new user is appended to the list. However the issues is, when I have already selected an item, edited it... then the textboxes are still populated w/ the item values... now if I click add new user... a new user is added... but now I have duplicate users in my list.. which is fine because I can always edit one of them... However.... it looks like both the new and the old user are now somehow linked... if I edit one of them, the values in the other also change... (I hope this makes sense). I feel that because the new user was created via the selected record of the old user, somehow their indexes are related....can't seem to figure out how to create a new user without having the old user connected to it.</p>
<p>(2) Deleting a user works fine, but except, the user deleted is always from the bottom of the list. I want to be able to select any item in the list and delete that specific item. I tried using something like:-</p>
<pre><code>$scope.userList.splice($scope.userList.indexOf(currentUser), 1);
</code></pre>
<p>but to no avail.</p>
<p>My Javascript:- </p>
<pre><code><script type="text/javascript">
function UserController($scope) {
$scope.userList = [
{ Name: "John Doe1", Title: "xxxx", Company: "yyyy", Place: "zzzz" },
{ Name: "John Doe2", Title: "xxxx", Company: "yyyy", Place: "zzzz" },
{ Name: "John Doe3", Title: "xxxx", Company: "yyyy", Place: "zzzz" },
{ Name: "John Doe4", Title: "xxxx", Company: "yyyy", Place: "zzzz" }
];
$scope.selectUser = function (user) {
$scope.currentUser = user;
}
$scope.addNew = function (currentUser) {
$scope.userList.push(currentUser);
$scope.currentUser = {}; //clear out Employee object
}
$scope.removeItem = function (currentUser) {
// $scope.userList.pop(currentUser);
$scope.userList.splice($scope.userList.indexOf(currentUser), 1);
$scope.currentUser = {}; //clear out Employee object
}
}

Best practice for merging solution files with project id conflicts | <p>Let's say a TFS branch was created out of some main branch which had 2 projects (FirstNewProject) but while the work was still ongoing in that branch, another branch was created (SecondNewProject) the task was finished and that other branch was merged back down.</p>
<p>If we now try to merge that first branch back into the main branch from which both of these branches were branched we now have a conflict in the solution file which can apparently only be manually resolved...</p>
<p>The first conflict is with <code>SccNumberOfProjects = 3</code> TFS variable which is the same in both FirstNewProject and SecondNewProject solution files but needs to be changed to <code>SccNumberOfProjects = 4</code> because when SecondNewProject was merged back down the number of projects was 3 but now that we're merging the FirstNewProject the number of projects is now 4.</p>
<p>Would changing this variable manually to 4 create an invalid solution file?</p>
<p>The second conflict is within Global section and it has to do with project numbering.</p>
<p>SecondNewProject added these lines to solution file:</p>
<pre><code>SccProjectUniqueName3 = SecondNewProject\\SecondNewProject.csproj
SccProjectName3 = SecondNewProject
SccLocalPath3 = SecondNewProject
</code></pre>
<p>FirstNewProject added these lines to solution file:</p>
<pre><code>SccProjectUniqueName3 = FirstNewProject\\FirstNewProject.csproj
SccProjectName3 = FirstNewProject
SccLocalPath3 = FirstNewProject
</code></pre>
<p>But FirstNewProject is now 4th project so should we change these entries to </p>
<pre><code>SccProjectUniqueName4 = FirstNewProject\\FirstNewProject.csproj
SccProjectName4 = FirstNewProject
SccLocalPath4 = FirstNewProject
</code></pre>
<p>manually and will that make the solution file invalid and is there anything else to be done when merging back down in a situation like this one?</p> | 1 |
Catching Exceptions from library using Laravel 5.2 | <p>Pretty new to laravel, so I'm not exactly sure how it handles errors and how best to catch them.</p>
<p>I'm using a 3rd party game server connection library that can query game servers in order to pull data such as players, current map etc..</p>
<p>This library is called Steam Condenser : <a href="https://github.com/koraktor/steam-condenser" rel="nofollow">https://github.com/koraktor/steam-condenser</a></p>
<p>I have imported this using composer in my project and all seems to be working fine, however I'm having trouble with catching exceptions that are thrown by the library.</p>
<p>One example is where the game server you are querying is offline.</p>
<p>Here is my code:</p>
<pre><code>public function show($server_name)
{
try{
SteamSocket::setTimeout(3000);
$server = server::associatedServer($server_name);
$server_info = new SourceServer($server->server_ip);
$server_info->rconAuth($server->server_rcon);
$players = $server_info->getPlayers();
$total_players = count($players);
$more_info = $server_info->getServerInfo();
$maps = $server_info->rconExec('maps *');
preg_match_all("/(?<=fs\)).*?(?=\.bsp)/", $maps, $map_list);
}catch(SocketException $e){
dd("error");
}
return view('server', compact('server', 'server_info', 'total_players', 'players', 'more_info', 'map_list'));
}
</code></pre>
<p>If the server is offline, it will throw a SocketException, which I try to catch, however this never seems to happen. I then get the error page with the trace.</p>
<p>This causes a bit of a problem as I wish to simply tell the end user that the server is offline, however I cannot do this if I can't catch this error.</p>
<p>Is there something wrong with my try/catch? Does laravel handle catching errors in this way? Is this an issue with the 3rd party library?</p> | 1 |

How to inject upgraded Angular 1 service/factory to Angular 2 component in ES5? | <p>I have an Angular1 service with name, say, 'myService'</p>
<p>I then upgraded it using the Angular2 UpgradeAdapter like this:</p>
<pre><code>var upgradeAdapter = new ng.upgrade.UpgradeAdapter();
upgradeAdapter.upgradeNg1Provider('myService');
</code></pre>
<p>Now I need to inject it to the angular2 component. Official upgrade guide only has typescript version for now. In typescript you use @Inject anotation with the service name for it like so:</p>
<pre><code>export class MyComponent {
constructor(@Inject('myService') service:MyService) {
...
}
}
</code></pre>
<p>What is the syntax for injecting a service by name using ES5?</p> | 1 |
Set ValidateAntiForgeryToken attribute to GET/POST for same action MVC5 | <p>My question is very straight forward...</p>
<p>I have an <code>Action</code> which accepts both <code>HttpGet</code> and <code>HttpPost</code>, but I want to set <code>ValidateAntiForgeryToken</code> attribute to the action when the http request is <code>POST</code>, not for <code>HttpGet</code>. </p>
<p>I can find whether the request is <code>GET</code> or <code>POST</code> inside the action, but I need to know before the action called.</p>
<pre><code> [ValidateAntiForgeryToken] // Only for HttpPost
public ActionResult Index() // Allows HttpPost / HttpGet
{
}
</code></pre>
<p>Is there any possibilities to achieve this without duplicating the action?</p>

Navigation with only Back Button and transparent background | <p>I had tried to implement Navigation Controller which embeds in my View Controller. It works as expected. </p>
<p>But my requirement is slightly different which needs only a back button and already have a top banner with logo image background in all the screens . So if I try to implement back button it takes the space for the navigation bar which covers the Logo/top banner. </p>
<p>Is there any way to overcome this scenario . </p> | 1 |

Generic insertionSort using a Comparator object as a parameter? | <p>If I'm given this method header: </p>

* This generic method sorts the input array using an insertion sort and the input Comparator object.

public static <T> void insertionSort(T[] array , Comparator<? super T> comparatorObj){
// Implement method

<p>For the <code>Comparator<? super T> comparatorObj</code> part in the parameter, am I suppose to be making a comparator object method that tells how it should be comparing when it's used in the insertionSort parameter?</p> | 1 |
CISC and RISC architectures | <p>I read a lot about the difference between CISC and RISC architectures from different sources.

Display results of join query in blade | <p>I'm having a bit of a struggle displaying results from a query in a blade template. The basics: I have two tables; countries and issuers. The Country model has a hasMany relation to Issuer, and vice versa. Both relations are properly defined in the models. I am trying to display a list of issuers that contains the name (nation) of the country as well. My query, in the IssuersController, is as follows: </p>
<pre><code> $issuers = ISSUER::join('countries', 'issuers.country_id', '=', 'countries.id')
->select('issuers.*', 'countries.nation')
->orderBy('nation', 'asc')
->orderBy('author', 'asc')
->get();
</code></pre>
<p>This query works and dd(); shows it returning an array for each issuer that includes all of the issuer data as well as the corresponding country name as nation. Perfect. However, when I attempt to display this in my view I run into a wall. My first attempt was to just use </p>
<pre><code> @foreach($issuers as $issuer)
<tr>
<td>{{ $issuer->id }}</td>
<td>{{ $issuer->nation }}</td>
<td>{{ $issuers->author }}</td>
</code></pre>
<p>This returns an undefined variable on $nation. I'm not sure why this happens as I'm not attempting to access the relationship. I'm simply trying to access the results of an array that was returned from the query. The relationship should not be relevant at that point. Anyway, attempting to use the relationship I try </p>
<pre><code> @foreach($issuers as $issuer)
<tr>
<td>{{ $issuer->id }}</td>
@foreach($issuer->nation as $nation)
<td>{{ $issuer->nation }}</td>
@endforeach
<td>{{ $issuers->author }}</td>
</code></pre>
<p>Which returns and invalid argument supplied in foreach() error. Next I attempt to use the method...</p>
<pre><code> @foreach($issuers as $issuer)
<tr>
<td>{{ $issuer->id }}</td>
@foreach($issuer->Country() as $nation)
<td>{{ $issuer->nation }}</td>
@endforeach
<td>{{ $issuers->author }}</td>
</code></pre>
<p>This throws no error but also returns nothing. The colum is simply skipped and everything else that is echoed gets shifted one column to the left. </p>
<p>I'm sort of lost here and I think it's because my brain is stubbornly holding on to the idea that I'm accessing elements of a query result rather than elements of a relationship, so I can't quite figure out why I need a separate loop for that one column, or how that loop should work. Any help would be appreciated.</p>

how do I use Artemis with Camel Java DSL using the camel-jms component? | <p>Right now I'm using JMS 2.0 with Artemis 1.2.0 on a Java EE 7 application and I would like to do some integration tasks with Camel.</p>
<p>Right now checking the camel-jms documentation, there is no mention whatsoever on how to use the generic camel JMS component to produce and consume messages to any JMS 2.0 compliant broker.</p>
<p>The only example on <a href="http://camel.apache.org/jms.html" rel="noreferrer">the component documentation</a> is configuring an ActiveMQ connection factory with its specialized ActiveMQ component using the Spring DSL. How can I configure a connection for Camel JMS to connect to my Artemis instance?</p>
<p>Take into account that even though Artemis is compatible with ActiveMQ 5.x, I'm going to use a Camel route to publish and subscribe to shared durable topics, so I need to be able to configure an Artemis connection and do a publisher and a shared durable subscriber with it (only supported in JMS 2.0, ActiveMQ only supports JMS 1.1).</p>

ReportViewer column group page break | <p>I need to generate a daily employee attendance report using ASP.NET ReportViewer. It must be grouped by month, meaning I have to set page break based on the <code>monthName</code> field. </p>
<p>I come up with the following design in my RDLC report:</p>
<p><a href="https://i.stack.imgur.com/JaNqM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JaNqM.png" alt="enter image description here"></a></p>
<p>The result is:
<a href="https://i.stack.imgur.com/0KgKZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0KgKZ.png" alt="enter image description here"></a></p>
<p>At first, everything is fine. The first page shows the attendance for the month of January, from Jan. 1 to 31. Clicking on the "Next Page" button on the report shows the employee attendance record for the next month (i.e. February.) </p>
<p>But employees can be quite numerous thus it is better to be rendered as a row instead of as a column. No problem. I can just redesign the report and again, set the page break to <code>[monthName]</code> such as:</p>
<p><a href="https://i.stack.imgur.com/bosdw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bosdw.png" alt="enter image description here"></a></p>
<p>To my surprise, it doesn't work. I found out in MSDN that <strong>page break is not allowed in column group</strong>!</p>
<p>My question is:</p>
<ol>
<li><p>What's the problem with setting column group page breaks? Why did
<em>they</em> set this limitation?</p></li>
<li><p>What's the workaround to accomplish this? I'm sure you people have
also tried to accomplish the same task and succeed.</p></li>

Disabling of TCP SYN retransmission | <p>I am developing a client which connects to server through TCP. Servers are configured such that if one server is down, connection is set up with another server. </p>
<p>My requirement is that if TCP connection is not established with the 1st server within 2s, client needs to establish connection with the 2nd server.</p>
<p>Below is my observation based on testing-
TCP SYN message is sent by client to the 1st server to establish connection. Since 1st server is down, after 1s, TCP SYN retransmission is sent to the 1st server. After 2s(owing to processing and network delays), TCP SYN message is sent to the 2nd server by the client. So its taking 3s (1s + 2s) for the SYN message to be sent to the 2nd server, which is not what I wanted. I want the TCP SYN message to be sent to 2nd server within 2s.</p>
<p>In order to send TCP SYN message to the 2nd server within 2s, I want to avoid TCP SYN retransmission. </p>
<p>I tried setting net.ipv4.tcp_syn_retries=0 in /etc/sysctl.conf. But I get 1 TCP SYN retransmission.</p>
<p>So is there any way to disable TCP SYN retransmission from userspace without changing the kernel source?</p> | 1 |

In my understanding, every expression that is an instance of <code>AutoClosable</code> should provide the <code>use</code> extension function.</p>
<p>Here is a complete example:</p>
<pre><code>import java.io.BufferedReader;
import java.io.FileReader;
import org.openrdf.query.TupleQuery;
import org.openrdf.query.TupleQueryResult;
public class Test {
static String foo(String path) throws Throwable {
try (BufferedReader r =
new BufferedReader(new FileReader(path))) {
return "";
}
}
static String bar(TupleQuery query) throws Throwable {
try (TupleQueryResult r = query.evaluate()) {
return "";
}
}
}
</code></pre>
<p>The Java-to-Kotlin converter creates this output:</p>
<pre><code>import java.io.BufferedReader
import java.io.FileReader
import org.openrdf.query.TupleQuery
import org.openrdf.query.TupleQueryResult
object Test {
@Throws(Throwable::class)
internal fun foo(path: String): String {
BufferedReader(FileReader(path)).use { r -> return "" }
}
@Throws(Throwable::class)
internal fun bar(query: TupleQuery): String {
query.evaluate().use { r -> return "" } // ERROR
}
}
</code></pre>
<p><code>foo</code> works fine, but the code in <code>bar</code> does not compile: </p>
<pre><code>Error:(16, 26) Kotlin: Unresolved reference.
None of the following candidates is applicable
because of receiver type mismatch:
public inline fun <T : java.io.Closeable, R>
???.use(block: (???) -> ???): ??? defined in kotlin.io
</code></pre>
<p><code>query.evaluate()</code> is from <a href="http://rdf4j.org/" rel="noreferrer">Sesame</a> and implements <code>AutoClosable</code>. Is it a Kotlin bug, or is there a reason why it does not work?</p>

Grails RestBuilder query parmeters | <p>I'm writing some functional tests for a Grails controller, and I feel it's getting messy when testing the query parameters.</p>
<p>I know that I can do this, but it just seems clunky. </p>
<pre><code>Map getParms = [id:1, x:foo, y:bar, z:baz]
RestResponse response = builder.get("http://example.com/api/{id}?x={x}&y={y}&z={z}") {
urlVariables getParams
}
</code></pre>
<p>Ideally I'd like to:</p>
<ol>
<li>Fill the base URL (i.e. the Id) using the <code>urlVariables</code> argument above</li>
<li>Pass another map of query params that appends each as a key value pair</li>
</ol>
<p>Something like:</p>
<pre><code>Map queryParms = [x:foo, y:bar, z:baz]
RestResponse response = builder.get("http://example.com/api/{id}") {
urlVariables id:1
queryVariables queryParams
}
</code></pre>
<p>I feel this would be much more 'DRY', and easier to read/write.</p>
<p>Does anyone know if such a mechanism exists? I know I could put together a class to do it, but I was hoping to avoid this if there is an existing implementation.</p> | 1 |
proxmox KVM routed network with multiple public IPs | <p>I have a dedicated hosting with hetzner. Additionally i have bought a 6IP subnet.</p>

apache phoenix Join query performance | <p>I started using phoenix couple of months back. Below are the environment and version details.</p>
<p>Hadoop – Cloudera CDH 5.4.7-1.
Phoenix – 4.3 – Phoenix which comes as parcels on CDH5.4.7-1.
HBase version – HBase 1.0.0
JDK – 1.7.0_67
1 Master and 3 region servers.</p>
<p>We started to do a POC to evaluate Apache Phoenix. We have data in 12 different tables on Oracle DB. We get the data into Hadoop system using Oracle golden gate.</p>
<p>There are 12 different Phoenix tables each having 40-100 columns with a few hundred rows. We do a transformation process and then load into a final table. This is basic ETL which we are doing. The transformation process goes through a couple of intermediate stages where we populate intermediate tables. Hence there are “joins” between tables. </p>
<p>Everything worked great and we were able to implement the entire ETL process. I was very happy with the ease of use and implementation. </p>
<p>The issues started when we started with the Performance testing with millions of rows. Below are the issues.</p>
<ol>
<li><p>The intermediate transformation process crashes the region servers: Joining two tables, each with 20 Million rows. Secondary Index created on the column I am joining on. The two tables are salted with 9 buckets. This performed well if the number of rows resulted from the join is less than ~200k. The 200k rows take more than 10 minutes to execute. If the number of rows resulting is more, then the region servers start crashing.
Test code
explain select count(available_bal) from salted.b_acct2 ba
inner join
(select c_item_id from salted.m_item2 mi where s_info_id = 12345) as mi
on ba.c_item_id = mi.c_item_id;</p>
<p>+------------------------------------------+
| PLAN |
+------------------------------------------+
| CLIENT 9-CHUNK PARALLEL 9-WAY FULL SCAN OVER SALTED.S2_BA_CI_IDX |
| SERVER AGGREGATE INTO SINGLE ROW |
| PARALLEL INNER-JOIN TABLE 0 (SKIP MERGE) |
| CLIENT 9-CHUNK PARALLEL 9-WAY RANGE SCAN OVER SALTED.S_MI_SI_IDX [0,19,266] |
| CLIENT MERGE SORT |
| DYNAMIC SERVER FILTER BY TO_BIGINT("C_ITEM_ID") IN (MI.C_ITEM_ID) |
+------------------------------------------+</p></li>
<li><p>Joining 6 tables for the final transformation hangs: Joining 6 tables on indexed columns returns data for less than 1M rows. This takes 10-12 minutes. But if the join results are approximately more than 1M, it hangs and the result doesn’t come back. Initially I got InsufficientMemoryException, which I resolved by changing the configuration and increasing the memory available. I don’t get the InsufficientMemoryException again, but the query doesn’t execute for more than 20 min. We are expecting to execute within a few seconds.</p></li>
</ol>
<p>Below are the parameters:</p>
<pre><code>jvm.bootoptions= -Xms512m –Xmx9999M.
hbase.regionserver.wal.codec : org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec
hbase.rpc.timeout 600000
phoenix.query.timeoutMs 360000000
phoenix.query.maxServerCacheBytes 10737418240
phoenix.coprocessor.maxServerCacheTimeToLiveMs 900000
hbase.client.scanner.timeout.period 600000
phoenix.query.maxGlobalMemoryWaitMs 100000
phoenix.query.maxGlobalMemoryPercentage 50
hbase.regionserver.handler.count 50
</code></pre>
<p>Summary: The core issues being Slow execution of join queries and eventually crashing of region servers when the data goes beyond 1 million of rows. Is there a limitation on the execution? Please help me resolve these issues as we are going through an evaluation process and I don’t want to let go of Phoenix! If I am able to execute the above queries within quick time, then I would not hesitate to use Phoenix.</p>

Webpack exclude entries for CommonsChunkPlugin | <p>I am trying to set up webpack production configuration. All looks well. However, I realized that while using the commons chunk plugin, it covers all the files in common as expected. What I want to do is, separation of common library modules and common application modules. My config file is :</p>
<pre><code>module.exports = {

lib: ["react", "react-dom"],
app: "./ui-v2/app/app.js",
app2: "./ui-v2/app/app2.js"
},

<p>Basically I have 3 modules in the app; app.js, app2.js and a common component user.js.</p>
<p>What I want to achieve is to bundle all library related files like react, react-dom, lodash, etc in a lib bundle, and common application components like user.js in a common bundle. In order to do this, I thought there might be an option to exclude the files that I don't want them to go to "common" file. If I use this output, what is the point for long term caching files for library bundles because whenever I get a common component in my project, they will go into the common bundle and the content hash will be different, but nothing changes in this library files like react, jquery, lodash, etc.</p>
<p>Anyway, what I have at the end of build process is everything still goes into the common bundle and lib has nothing and the file sizes are :</p>
<pre><code>app.<hash>.min.js -> 3.05KB
app2.<hash>.min.js -> 3.05KB
lib.<hash>.min.js -> 165 Bytes (has almost nothing!)
common.<hash>.js -> 678 KB
</code></pre>
<p>Is there any way to achieve what I want or what would be the best approach to a production build in similar cases? Thank you!</p> | 1 |
How to create condition "if element not exist - do smth" by using Nightwatch? | <p>I have a list of users, presented by table, and I need to search for td element with appropriate value - and if element not exist on current page - click on link to go on another page.
I have no ideas how to do this but I used xpath selector to find element with some value.</p>
<p>Each user presented by "tr" element and contains "td" elements inside:</p>
<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><tr>
<td class="break-all">acceptance</td>
<td>client</td>
<td class="break-all"></td>
</tr></code></pre>
</div>
</div>
</p>
<p>So, I need to find td element with value = "acceptance", if it's not exist on current page - click on link to go on another page and continue the search.</p>
<p><strong>I found solution, and it works for me!</strong></p>
<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function isActive(client) {
client.getAttribute("div.right", "class", function (result) {
if (result.value == "right active") {
client
.click("div.icon-caret-right")
.perform(function () {
findByText(client)
})
} else {
//Throw error in this case!!!
}
})
}
function findByText(username, client) {
client.elements("xpath", "//td[text()='" + username + "']", function (result) {
if (!result.value.length) {
isActive(client)
}
})
}
module.exports = findByText;</code></pre>
</div>
</div>
</p>
<p>And I just call <code>findByText(username, client)</code>.</p>
<p>But now I have another question - how to throw error from <code>else</code> statement???</p> | 1 |
Laravel Validation Error customise format of the Response | <p>I am working with L5 Form Requests and don't I just love Taylor! Well, I am doing some AJAX requests and I still want to retain my form requests. The problem is that in the case of a validation error the Validator just returns a 422 error response and flashes the errors, but my AJAX frontend expects a very specific format of response from server whether validation is successful or not.
</p>
<p>I want to format the response on Validation errors to something like this </p>
<pre><code>return json_encode(['Result'=>'ERROR','Message'=>'//i get the errors..no problem//']);
</code></pre>
<p>My problem is how to format the response for the form requests, especially when this is not global but done on specific form requests.
<p>
I have googled and yet not seen very helpful info. Tried this method too after digging into the <code>Validator</code> class.</p>
<pre><code>// added this function to my Form Request (after rules())
public function failedValidation(Validator $validator)
{
return ['Result'=>'Error'];
}
</code></pre>
<p>Still no success.</p> | 1 |
IntelliJ shows shorthand package names.

scale the loss value according to "badness" in caffe | <p>I want to scale the loss value of each image based on how close/far is the "current prediction" to the "correct label" during the training. For example if the correct label is "cat" and the network think it is "dog" the penalty (loss) should be less than the case if the network thinks it is a "car".</p>
<p>The way that I am doing is as following:</p>
<p>1- I defined a matrix of the distance between the labels,<br>
2- pass that matrix as a bottom to the <code>"softmaxWithLoss"</code> layer,<br>
3- multiply each log(prob) to this value to scale the loss according to badness in <code>forward_cpu</code></p>
<p>However I do not know what should I do in the <code>backward_cpu</code> part. I understand the gradient (bottom_diff) has to be changed but not quite sure, how to incorporate the scale value here. According to the math I have to scale the gradient by the scale (because it is just an scale) but don't know how.</p>
<p>Also, seems like there is loosLayer in caffe called <code>"InfoGainLoss"</code> that does very similar job if I am not mistaken, however the backward part of this layer is a little confusing:</p>
<pre><code>bottom_diff[i * dim + j] = scale * infogain_mat[label * dim + j] / prob;
</code></pre>
<p>I am not sure why <code>infogain_mat[]</code> is divide by <code>prob</code> rather than being multiply by! If I use identity matrix for <code>infogain_mat</code> isn't it supposed to act like softmax loss in both forward and backward?</p>
<p>It will be highly appreciated if someone can give me some pointers.</p> | 1 |

IntelliJ IDEA 15 Scene Builder not showing all controls | <p>I have troubles with the built in Scene Builder. When used standalone Scene Builder displays everything fine. Did I mess up some settings in IntelliJ Idea or it's a bug. </p>
<p>I use IntelliJ Idea 15.0.3 (64 bit) and Scene Builder 2.0.</p>
<p>One thing I changed in IntelliJ was the heap size. Here is my idea64.exe.vmoptions file:
-Xms512m
-Xmx2048m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=256m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow</p>
<p>I increased -Xmx to 2GB because it was complaining that it needs more ram ... hungry java... That's also the reason I switched to 64 bit version. The 32 bit didn't want to boot with more than 1.1GB heap. I noticed that SceneBuilder about dialog sais "Operating System: Windows 7, x86, 6.1". Does it have troubles working with 64 JRE? It's java, it shouldn't matter what's below...</p>
<p>I'll post an update when I try Scene Builder with idea running with 32-bit JRE.</p>
<p><strong>Update:</strong> IntelliJ with 32 bit JRE acts the same way.</p>

How to set node color different in one cluster using R {igraph}? | <p>I have a set of data of city, each city have a majority etnic. Let's say</p>
<pre><code>City Etnic
A x
B y
C z
</code></pre>
<p>etc. I make a graph of social network where the node represent the name of the city, and the link is the neighborhood of the city with another city. I'm using package igraph in R.
After that I do graph partitioning to find it's community. Let's say it came with 4 communities. And in one community, there was multiple etnic. The node color represent the majority etnic.
The problem is, the node color of graph is following the community. This is my code:</p>
<pre><code>#make a graph from data frame
g=graph.data.frame(link, directed=T, vertices=node)
#clustering/graph partitioning
clust=cluster_optimal(g)
#node color
V(g)$color <- ifelse(V(g)$etnic == "x", "red",ifelse(V(g)$etnic =="y", "blue", "green")
plot(clust, g, edge.arrow.size=.15, edge.curved=0, vertex.frame.color="black",
vertex.label=V(g)$city, vertex.label.color="black",
vertex.label.cex=.8,layout=l)
</code></pre>
<p>The question is how I make the node color represent the color of etnic I declare?</p> | 1 |

<pre><code>total = pd.to_numeric(sales_df.Sales.str.replace("$", "")).sum()
</code></pre>
<p>But I don't want <code>Sales</code> to be hard coded, I want a variable to make it dynamic. How is this done?</p>

Using webpack and react-router for lazyloading and code-splitting not loading | <p>I'm working on moving my <code>react v0.14</code>+ <code>redux v3.0</code> + <code>react-router v1.0</code> codebase from client-side rendering to server-side rendering using <code>webpack v1.12</code> to bundle and code-split into chunks to load routes and components on-demand.</p>
<p>Im following and basing my setup on <a href="https://github.com/rackt/example-react-router-server-rendering-lazy-routes">https://github.com/rackt/example-react-router-server-rendering-lazy-routes</a> as I think it provides simplicity and great utilities. All day yesterday I have been working on moving to server-side rendering but I run into a few issues I haven't been able to solve and I'm not completely sure if they are because of <code>webpack</code> not being setup correctly, if am doing something wrong with <code>react-router</code> on the server/client or the routes config, or if its something I'm doing wrong with setting up <code>redux</code> that is causing these issues.</p>
<p>I run into the following issues:</p>
<ol>
<li>I'm able to load the initial page and everything works well but no other routes load and gives me <a href="http://i.stack.imgur.com/YFga4.png">GET http://localhost:3000/profile 404 (Not Found)</a></li>
<li>The index/home page javascript works but all assets(css) are rendered as <code>text/javascript</code> so the styles don't show up unless they are inline.</li>

Force UIViewController to layout correctly without bringing it onto the screen | <p>I am having some difficulty with the following problem. I have laid out a UIViewController in Storyboard with the correct constraints. It has all the same views as the UIViewController on the screen at the present. I am using this new UIViewController for some resizing. Therefore, I would like to initialize this UIViewController, layout all the subviews, according to the constraints I have given it, and then use the UIView's frames for the primary UIViewController. Since I never need this secondary UIViewController, it is never displayed. </p>
<p>I instantiate the secondary UIViewController as follows:</p>
<pre><code>secondaryVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("secondaryVCId") as? secondaryVC
</code></pre>
<p>This works fine, but getting the positions of the subviews, the most important thing, does not. Even though the view is sized correctly, (i.e. when <code>secondaryVC.view.size</code> is printed, it is the same as <code>primaryVC.view.size</code>) but the subviews still think that the view is 600 x 600. I have tried many things to force the subviews to layout again, but none seem to work, other than adding the view as a subview, (i.e. <code>primaryVC.view.addSubview(secondaryVC.view)</code>) which I would prefer not to do, (because I would then have to remove it again.)</p> | 1 |

Mongoose Pre-Save Hook is Firing, but Not Saving Additional Field (NOT using model.update) | <p>I am attempting to implement a counter in my schema to grab the next issue number. I have implemented it as a hook pre-save hook in Mongoose, and everything looks fine... with the exception the actual 'number' field does not update. I can easily tell the hook is firing off by what gets logged to the console, even the field seems to get assigned. But alas, no matter what I try, the 'number' field does not end up in the results.</p>
<p>I have seen a couple issues related to Mongoose hooks, but they all seem to be related to findOneAndUpdate or the like, which I am not using.</p>
<p><strong>Here is my full model with the hooks at the bottom:</strong></p>
<pre><code>var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var Project = require('./projects.js');
var IssueSchema = new Schema({

Update a subset of weights in TensorFlow | <p>Does anyone know how to update a subset (i.e. only some indices) of the weights that are used in the forward propagation?</p>
<p>My guess is that I might be able to do that after applying compute_gradients as follows:</p>
<pre><code>optimizer = tf.train.GradientDescentOptimizer(learning_rate=learning_rate)
grads_vars = optimizer.compute_gradients(loss, var_list=[weights, bias_h, bias_v])
</code></pre>
<p>...and then do something with the list of tuples in <code>grads_vars</code>.</p> | 1 |
Rails: Set config.time_zone to the server's time zone? | <p>For compatibility reasons I need to store and display all dates in the server's local time zone. To do this I configured the rails application like this in <code>application.rb</code>:</p>
<pre><code># Do not convert database DATETIME / DATE columns to UTC:
config.active_record.default_timezone = :local
</code></pre>
<p>It works okay when I store dates they are stored in the server's local timezone. However when retrieving the data Rails converts it to UTC, so for example <code>Post.find(1).posted</code> returns <code>2016-02-02 18:06:48 UTC</code> but it is actually stored as <code>2016-02-02 13:06:48</code> in the database.</p>
<p>How can I keep Rails from converting it to UTC?</p>
<p>I thought that setting the application time zone to the server's local time zone will help so I wanted to set <code>config.time_zone</code> to the server's local time zone and tried with:</p>
<pre><code>config.time_zone = Time.now.zone
</code></pre>
<p>But the problem with it is that it returns a three character timezone code like <code>COT</code> and config.time_zone is expecting a Time Zone name like <code>Bogota</code></p>
<p>How can I translate the three character code to the full time zone name? or, how can I get the local time zone name? or, how can I configure Rails to not convert the database dates to UTC?</p> | 1 |

Why does Spark throw "SparkException: DStream has not been initialized" when restoring from checkpoint? | <p>I am restoring a stream from a HDFS checkpoint (ConstantInputDSTream for example) but I keep getting <code>SparkException: <X> has not been initialized</code>.</p>
<p>Is there something specific I need to do when restoring from checkpointing?</p>
<p>I can see that it wants <code>DStream.zeroTime</code> set but when the stream is restored <code>zeroTime</code> is <code>null</code>. It doesn't get restored possibly due to it being a private member IDK. I can see that the <code>StreamingContext</code> referenced by the restored stream does have a value for <code>zeroTime</code>.</p>
<p><code>initialize</code> is a private method and gets called at <code>StreamingContext.graph.start</code> but not by <code>StreamingContext.graph.restart</code>, presumably because it expects <code>zeroTime</code> to have been persisted.</p>
<p>Does someone have an example of a Stream that recovers from a checkpoint and has a non null value for <code>zeroTime</code>?</p>
<pre><code>def createStreamingContext(): StreamingContext = {
val ssc = new StreamingContext(sparkConf, Duration(1000))
ssc.checkpoint(checkpointDir)
ssc
}
val ssc = StreamingContext.getOrCreate(checkpointDir), createStreamingContext)
val socketStream = ssc.socketTextStream(...)
socketStream.checkpoint(Seconds(1))
socketStream.foreachRDD(...)

Getting the html-cocde of the normal youtubevideo (on youtube.com) and extracting and decoding the .googlevideo urls.

SQLAlchemy ORM DateTime with specific format | <p>I have a table which stores a datetime value in the following format: (e.g.) 20160213145512. Unfortunately, SQLAlchemy gives me no chance to specify the format used to store a datetime value into the database with sqlalchemy´s DateTime type.</p>
<p>Therefore, i have created the following dataype:</p>
<pre><code>class Timestamp(TypeDecorator):
impl = String(14)
def process_bind_param(self, value, dialect):
if isinstance(value, datetime):
value = '%04d%02d%02d%02d%02d%02d' % (value.year,
value.month,
value.day,
value.hour,
value.minute,
value.second)
return value
def process_result_value(self, value, dialect):
if value:
return datetime(year=int(value[0:4]),
month=int(value[4:6]),
day=int(value[6:8]),
hour=int(value[8:10]),
minute=int(value[10:12]),
second=int(value[12:14])
)
</code></pre>
<p>I do not use strftime and strptime for performance reasons.
What I am now able to do is the following:</p>
<pre><code>class TestTable(Base):
__tablename__ = "TESTTABLE"
id = Column(Integer, primary_key=True)
timestamp = Column(Timestamp)
</code></pre>
<p>Insert row by defining the datetime via a datetime object:</p>
<pre><code>session.add(TestTable(timestamp=datetime(year=2016, month=2, day=3, hour=2)))
</code></pre>
<p>Or inserting a row by defining datetime as a string:</p>
<pre><code>session.add(TestTable(timestamp="20160203031422"))
</code></pre>
<p>So far, so good.
But the following is not working as expected:</p>
<pre><code>session.query(TestTable).filter(TestTable.timestamp.year == 2016).all()
</code></pre>
<p>If I am runnning this code snippet I get this error:</p>
<pre><code>AttributeError: Neither 'InstrumentedAttribute' object nor 'Comparator' object associated with ORDERS.dz_statakt has an attribute 'year'
</code></pre>
<p>However this works:</p>
<pre><code>session.query(TestTable).filter(TestTable.timestamp.startswith("2016")).all()
</code></pre>
<p>Until now I was not able to solve this problem. I guess I am missing something in my own Timestamp class.</p>
<p>Is this possible at all?</p> | 1 |
Get frame from SurfaceTexture (Android) | <p>I'm using a <code>SurfaceTexture</code> to run the camera of a device in the background and get frames from it. I see that that <code>onFrameAvailable</code> callback don't bring a frame, but a <code>SurfaceTexture</code> instead. I want to get the frame or an image representation of it, but I'm not sure how to do that. When I searched I found that I need to use GraphicBuffer, but it seems too complicated and it's not clear to me how to use it. </p>
<p>I've also looked at solutions here: </p>
<p><a href="https://stackoverflow.com/questions/423663/texture-image-processing-on-the-gpu">Texture Image processing on the GPU?</a></p>
<p><a href="https://stackoverflow.com/questions/10775942/android-sdk-get-raw-preview-camera-image-without-displaying-it">Android SDK: Get raw preview camera image without displaying it</a></p>
<p>But it's not clear how to do it in the code. Here is my code: </p>
<pre><code>public class BackgroundService extends Service {
private Camera camera = null;
private int NOTIFICATION_ID= 1;
private static final String TAG = "OCVSample::Activity";
// Binder given to clients
private final IBinder mBinder = new LocalBinder();
private WindowManager windowManager;
private SurfaceTexture mSurfaceTexture= new SurfaceTexture (10);
Intent intializerIntent;
public class LocalBinder extends Binder {
BackgroundService getService() {
// Return this instance of this service so clients can call public methods
return BackgroundService.this;
}
}//end inner class that returns an instance of the service.
@Override
public IBinder onBind(Intent intent) {
intializerIntent = intent;
return mBinder;
}//end onBind.
@Override
public void onCreate() {
Log.i(TAG, "onCreate is called");
// Start foreground service to avoid unexpected kill
startForeground(NOTIFICATION_ID, buildNotification());
Thread thread = new Thread() {
public void run() {
camera = Camera.open(1);
mSurfaceTexture.setOnFrameAvailableListener(new SurfaceTexture.OnFrameAvailableListener() {
@Override
public void onFrameAvailable(SurfaceTexture surfaceTexture) {
Log.i(TAG, "frame captured from texture");
if (camera!=null) {
//camera.setPreviewCallbackWithBuffer(null);
//camera.setPreviewCallback(null);
//camera.setOneShotPreviewCallback(null);
//if the following two lines are not called, many frames will be droped.
camera.stopPreview();
camera.startPreview();
}
}
});
//now try to set the preview texture of the camera which is actually the surfaceTexture that has just been created.
try {
camera.setPreviewTexture(mSurfaceTexture);
} catch (IOException e) {
Log.e(TAG, "Error in setting the camera surface texture");
}
camera.startPreview();
}
};
thread.start();
}
private Notification buildNotification () {
NotificationCompat.Builder notificationBuilder=new NotificationCompat.Builder(this);
notificationBuilder.setOngoing(true); //this notification should be ongoing
notificationBuilder.setContentTitle(getString(R.string.notification_title))
.setContentText(getString (R.string.notification_text_and_ticker))
.setSmallIcon(R.drawable.vecsat_logo)
.setTicker(getString(R.string.notification_text_and_ticker));
return(notificationBuilder.build());
}
@Override
public void onDestroy() {
Log.i(TAG, "surfaceDestroyed method");
camera.stopPreview();
//camera.lock();
camera.release();
mSurfaceTexture.detachFromGLContext();
mSurfaceTexture.release();
stopService(intializerIntent) ;
//windowManager.removeView(surfaceView);
}
}
</code></pre>
<p>How can I get the frames and process them whether that's on GPU or CPU? If there is a way to do that on GPU, then get the results from there, that would be great as it seems more efficient. </p>
<p>Thank you. </p> | 1 |
Java equivalent to python's "with" | <p>Python has a nice feature: the "with" statement. It's useful for making global changes that affect all code called within the statement.</p>
<p>e.g. you could define a class CapturePrintStatements to capture all print statements called within the "with"</p>
<pre><code>with CapturePrintStatements() as c:
print 'Stuff Done'
print 'More Stuff Done'
assert c.get_text() == 'Stuff Done'
</code></pre>
<p>Is there an equivalent in Java?</p> | 1 |
How to select/lock cell network frequency band? | <p>I am developing a very specialized piece of software for Android and I need the capability to select and lock on to a specific frequency band within the cell network. Does anyone know a way of doing this. I realize there is no API, but maybe by issuing AT commands directly to the modem chip or something?</p> | 1 |
EF Core column name from mapping api | <p>In EF 6.1 the mapping API was introduced where we could finally get access to table names and column names. Getting the table name is a very nice change in EF Core, but I have not yet uncovered how to get the column names.</p>
<p>For anyone interested here is how I got the table name in the latest version (RC1)</p>
<pre><code>context.Model.FindEntityType(typeof(T)).SqlServer().TableName
</code></pre>
<p>What is the current method to get column names or is this not available yet?</p> | 1 |
What is correct Native Library Path to use OpenCV in eclipse-ubuntu | <p>I have an issue in setting native library path for opencv in eclipse-ubuntu.i am using ubuntu 15.04.installed opencv 3.1.0 following this link <a href="http://milq.github.io/install-opencv-ubuntu-debian/" rel="noreferrer">http://milq.github.io/install-opencv-ubuntu-debian/</a>
and add new library(OpenCV) in eclipse and set it's jar path as</p>
<pre><code>/home/user/opencv-3.1.0/build/bin/opencv-310.jar
</code></pre>
<p>and native library path as</p>
<pre><code>/home/user/opencv-3.1.0/build/lib
</code></pre>
<p><code>lib</code> folder contains <code>.so</code> and <code>.a</code> files. But when i try to use Mat object it gives me error:here is <strong>Main Method</strong></p>
<pre><code>System.out.println("Welcome to OpenCV hhhh " + Core.VERSION);
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
Mat img=new Mat();
</code></pre>
<p>and here is screenshot of my code and console
<a href="https://i.stack.imgur.com/1jlRz.png" rel="noreferrer"><img src="https://i.stack.imgur.com/1jlRz.png" alt="enter image description here"></a>
it gives me error:</p>
<pre><code>Exception in thread "main" java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat()J

</code></pre>
<p>if i use mat like this</p>
<pre><code>Mat m1 =Imgcodecs.imread("/home/zed/Desktop/img.png");
</code></pre>
<p>then it gives me diff error:</p>
<pre><code>Exception in thread "main" java.lang.UnsatisfiedLinkError: org.opencv.imgcodecs.Imgcodecs.imread_1(Ljava/lang/String;)J

<p>am i giving right path for native library? If not then what is the right path for Native Library to use Opencv3.1.0 in eclipse-ubuntu</p> | 1 |
PostgreSQL query for a list of allowed values in a constraint? | <p>Given a PostgreSQL table named <code>requests</code> with a column named <code>status</code> and a constraint like this:</p>
<pre><code>ALTER TABLE requests ADD CONSTRAINT allowed_status_types
CHECK (status IN (
'pending', -- request has not been attempted
'success', -- request succeeded
'failure' -- request failed
));
</code></pre>
<p>In <code>psql</code> I can pull up information about this constraint like this:</p>
<pre><code>example-database=# \d requests
Table "public.example-database"
Column | Type | Modifiers
----------------------+-----------------------------+-------------------------------------------------------------------
id | integer | not null default nextval('requests_id_seq'::regclass)
status | character varying | not null default 'pending'::character varying
created_at | timestamp without time zone | not null
updated_at | timestamp without time zone | not null
Indexes:
"requests_pkey" PRIMARY KEY, btree (id)
Check constraints:
"allowed_status_types" CHECK (status::text = ANY (ARRAY['pending'::character varying, 'success'::character varying, 'failure'::character varying]::text[]))
</code></pre>
<p>But is it possible to write a query that specifically returns the <code>allowed_status_types</code> of pending, success, failure?</p>
<p>It would be great to be able to memoize the results of this query within my application, vs. having to maintain a duplicate copy.</p> | 1 |
Onsen 2.0 - Adding event listener to Ons-Switch with Javascript | <p>I fear I am missing something really simple, but I have tried multiple attempts with various errors. On to the code:</p>
<pre><code><script>
document.getElementById("optStats").on("change", function(e) {
alert("Switch changed!");
});
</script>
<ons-switch modifier="list-item" id="optStats"></ons-switch>
</code></pre>
<p>So the above does not work. It generates an error of <code>Uncaught TypeError: Cannot read property of on of null</code>. So I assumed that I needed to add the function to the onload init function but it still failed with the same error.</p>
<p>I have tried all the options listed here: <a href="https://onsen.io/guide/overview.html#EventHandling" rel="nofollow">https://onsen.io/guide/overview.html#EventHandling</a> without success. This would include using var instead of id and just about anything else listed that I thought would work.</p>
<p>Edit: Full code that is not working, but works in codepen without template tag.</p>
<pre><code><ons-template id="options.html" >
<ons-page>
<ons-toolbar>
<div class="center">Options</div>
</ons-toolbar>
<ons-list modifier="inset" style="margin-top:10px;">
<ons-list-item>
Detailed Stats
<ons-switch modifier="list-item" id="optStats"></ons-switch>
</ons-list-item>
</ons-list>
</ons-page>
</ons-template>
</code></pre>
<p>I am using this in ons.ready() and have tried it outside which results in the same error, <code>cannot read property of addEventListener</code>, as listed above for both.</p>
<pre><code>document.getElementById('optStats').addEventListener('change', function(e) {
console.log('click', e.target.checked);
});
</code></pre>
<p><strong>Last Update I swear:
FINALLY!!!! Thank you @Fran-dios!</strong></p>
<p>After working with this, init is not the event you want to use, you definitely want to use show for what I was trying to do.</p>
<pre><code>document.addEventListener("show", function(event){
if (event.target.id == "pgOptions") {
document.getElementById('optStats').addEventListener('change', function(e) {
localStorage.setItem('useDetailedStats', e.target.checked);
useDetailedStats = e.target.checked;
});
document.getElementById('optStats').setChecked(useDetailedStats);
}
},false);
</code></pre>
<p>For whatever reason, when using init on a <code><ons-tabbar></code>, whenever you would press the tab, it would cause the switch to change states. By using show, it does not. Additionally, when I logged the init action, the page, even though it was not being shown on app startup, was still being logged as being init twice. Show does not cause this. Either way, the code that @fran-dios provided is the correct basis to get what I needed and his answer is still correct, I just needed to use a different event.</p> | 1 |
