Postgresql query did not terminate, after restart the service postgresql doesn't start | <p>At my work I was running a complex query. I cancelled it and went home yesterday. This morning in the back the query was impossible to be terminated, also with the 'terminate backend' functionality. A colleague of mine restarted the host machine where postgres is installed. After the machine restart, the postgres database sever would not start up. </p>
<p>In my log files I see the error:</p>
<blockquote>
<p>'pg_ctl: this data directory appears to be running a pre-existing postmaster'</p>
</blockquote>
<p>I am not sure how to handle this problem. I could try to fix it or try to extrapolate the data from the save files. What is the most logical step to take and do you know how to fix this? </p>
<p>Earlier it gave this error message : </p>
<blockquote>
<p>2016-01-28 15:52:33 GMT FATAL: lock file "postmaster.pid" already exists<br>
2016-01-28 15:52:33 GMT HINT: Is another postmaster (PID 2100) running in data directory "C:/PostgreSQL/9.1/data"?</p>
</blockquote>
<p>UPDATE... I located the file postmaster.pid and deleted it. Now I am restarting the computer and hoping it will start.</p>
<p>UPDATE... It works now. I rebooted the computer and postgres just instantly started. Happy as a child but at the same time not fully satisfied because of the following forum: <a href="https://superuser.com/questions/553045/fatal-lock-file-postmaster-pid-already-exists">https://superuser.com/questions/553045/fatal-lock-file-postmaster-pid-already-exists</a> . Here it is stated to NEVER delete the postmaster.pid because of possible data corruption. So because of that I will backup all databases I have in postgres now.</p>
<p>So if anyone can share some more light on my ICT adventure of today I would be very satisfied. That is why I will not state that this question is answered, since I have no idea what went wrong and perhaps will run into it again someday. </p> | 1 |
Adding security headers to request in CXF | <p>I created a client based on a wsdl file.</p>
<p>I am using the following code to call a Web Service:</p>
<pre><code> PrivateService ser = new PrivateService();
PrivatePortType port = ser.getPrivateSOAPPort();
BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
"http://192.168.4.48/PrivateSimulator/PrivateWebService.svc");
bindingProvider.getRequestContext().put(BindingProvider.SOAPACTION_USE_PROPERTY, true);
bindingProvider.getRequestContext().put(BindingProvider.SOAPACTION_URI_PROPERTY, "CreateParty");
CreatePartyRequest createReq = new CreatePartyRequest();
createReq.setParam("123456");
createReq.setCallback("http://192.168.5.106:9999/Service");
try {
CreatePartyResponse resp = port.createParty(createReq);
PartyInfo ci = resp.getPartyInfo();
System.out.println(ci.getPartyId());
} catch (WSException e) {
e.printStackTrace();
}
</code></pre>
<p>On the createParty call I accept "Object reference not set to an instance of an object" exception message.</p>
<p>This is probably because the web service was written with C#, and, most likely, it expects oasis headers, in which it store username and password values.</p>
<p>The enevelope which I could create by now is:</p>
<pre><code><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<CreatePartyRequest xmlns="http://teleParty.QQQ.com/CCGW">

<callback>http://192.168.5.106:9999/Service</callback>
</CreatePartyRequest>
</soap:Body>
</soap:Envelope>
</code></pre>
<p>And the required enevelope is as follows:</p>
<pre><code><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

AngularJS : function triggers twice on ng-change while selecting any option from dropdown | <p>Actually I am new to angularjs and I am facing problem which confuses me alot.
I have written angularjs controller, it populates data in dropdown menu and selection of each option it should show particular location on map. To trigger event I have used ng-change.</p>

<p>Now the problem is whenever I click on any option from populated dropdown it calls filtermarkers() function twice, but usually it should not. Kindly share your idea to how to get rid of it.</p>
<p>It also shows me two empty options in populated dropdown list.</p>

UVM ports: put,get,export, analysis | <p>I am trying to master in UVM, and completely lost in UVM ports. Please help better understand the ports.</p>
<p>So as I understood there are 3 main types of ports</p>
<ol>
<li>Put-> get : producer put data and consumer gets the data. This is blocking statement.</li>
<li>Put-> Export->Imp</li>
<li>Analysis->Subscriber : producer transmit the data and other subscribers gets it. This is non-blocking statement.</li>
</ol>
<p>Also there are TLM_FIFOs which allows to buffer the transaction for later usage. It has 2 types: <code>uvm_tlm_fifo</code> and <code>uvm_tlm_analysis_fifo</code>.</p>
<p>And my questions are:</p>
<ol>
<li>Is my understanding right?</li>
<li>What is the difference between get and export?</li>
<li>What is the difference between <code>uvm_tlm_fifo</code> and <code>uvm_tlm_analysis_fifo</code>?</li>
</ol>

How do I use wdio.conf.js? | <p>I'm trying to use <code>webdriverio</code> with the <code>jasmine</code> test framework. I can run my test by typing <code>jasmine</code> at the command line. However, when I do <code>wdio wdio.conf.js</code> it opens a bunch of extra browsers which don't do anything. I'm just wondering what the point of the wdio.conf.js file is when I can just run jasmine at the commandline. Ultimately it's the same thing, right? However, I can't get the wdio.conf.js file to work in the same manner so it's useless to me. Perhaps I'm not managing the browser clients correctly but I don't see any guidelines on how this is commonly done. I read the documentation but it's pretty vague beyond auto-generating the wdio.conf file so that 'everything just works'. Am I supposed to use grunt or gulp to run my tests or are those tools separate from the wdio.conf idea?</p>
<p>I'm Just trying to get my head around all these different tools. All I need to do is make multiple automated tests to test a website. Thanks for your help.</p> | 1 |
how do i add vendor javascript to ember-cli 2.2 | <p>This might be a silly question stemming from unfamiliarity. I'm rewriting a project that was previously using Ember 1.7 in Ember 2.3, using Ember-cli v2.2</p>
<p>Now, in the old project, there were a couple of libraries being included manually on the index.html file, put in the scripts directory and then compiled. For example, let's say the JS asset I want to include is offline.js. </p>
<p>I understand that Ember-cli uses Bower and can be used to install bower components, like Bootstrap or moment.js and such. What about custom JS? I've put the file in offline.js, included it in index.html but that doesn't do anything. </p>
<p>I don't think I understand how to add/import vendor assets at all; how do add, say offline.js to the project and have it available throughout the application?</p> | 1 |

iOS network requests in a serial queue | <p>In my View Controller's I make network calls using a class called Client. Client is basically a wrapper around Alamofire (AFNetworking) network calls, so I have save (POST), get (GET), and delete (DELETE) methods. </p>
<p>Each view controller has an instance variable client, and user's can Create, Edit, and Delete objects like so:</p>
<pre><code>client.save(object) { error in
print(error)
}
client.delete(object)
</code></pre>
<p>I want to ensure that for a given client, the same object isn't being simultaneously deleted/modified. There may be multiple instances of Client dealing with the same user-editable objects. </p>
<p>My idea is to create a serial queue that all instances of a client will use to enqueue requests, however I'm running into issues with the closure's of each function. I want the requests to be done asynchronously (to avoid blocking main thread) and Alamofire uses closures, but I want the Client to treat the requests as synchronous so that they are performed in the order received and wait for all closures to complete before proceeding to the next request to avoid any conflicts.</p>
<p>My Client save method looks like this:</p>
<pre><code>dispatch_async(self.serialQueue) {
self.httpClient.post("url", object) { error in
// handle errors, maybe make another request, etc
}
}
</code></pre>
<p>How would I go about ensuring each request (and its closures) complete before the client executes the next request. I need to be able to support chained requests as well (so in a closure I'd make another request).</p> | 1 |

How to use NVIDIA K80? | <p>The machine has 4 NVIDIA K80s setuped and the outputs of <code>nvidia-smi</code> are the information of the 4 cards. Their GPU IDs are <code>0,1,2,3</code>.

But the CUDA programs always use the <code>FB</code> memory, with the <code>BAR1</code> memory left be free. When the CUDA programs allocate more than 12 Gb GPU memory in each card, an error of <code>Out of memory</code> will be occurred, but the <code>BAR1</code> memory still be not used. </p>

Issue with materialize-css and Webpack, module with an equal name when case is ignored, JQuery | <p>I have a basic single page React/Redux app that i am bundling using Webpack, all is working fine except the following error when i try to load the materialise-css js files. I have tried loading from the NPM module and the compiles source and the errors are the same.</p>
<pre><code>WARNING in ./~/jQuery/dist/jquery.js
There is another module with an equal name when case is ignored.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Rename module if multiple modules are expected or use equal casing if one module is expected.

<p>I am loading everything at the top of my entry file as follows:</p>

<p>and JQuery is loaded from an NPM module as follows:</p>
<pre><code>new webpack.ProvidePlugin({

<p>Now everything still works, it loads all the fonts, js files, and everything works/looks correct in the application, but a warning is there for a reason so i would really like to make it go away!</p>

How to remove special char in golang when reading file? | <p>I have a file like this:
<a href="http://i.stack.imgur.com/KY4Ai.png" rel="nofollow">Each line represents a Website</a></p>
<pre><code>1 www.google.com$
2 www.apple.com$
3 www.facebook.com$
</code></pre>
<p>I read it in golang like this:</p>
<pre><code>type ListConf struct {
File string
Datas map[string]struct{}
}
func loadListConf(conf *ListConf, path string) {
file, err := os.Open(path + "/" + conf.File)
if err != nil {
fmt.Println("Load conf " + conf.File + " error: " + err.Error())
return
}
defer file.Close()
conf.Datas = make(map[string]struct{})
buf := bufio.NewReader(file)
end := false
for !end {
line, err := buf.ReadString('\n')
if err != nil {
if err != io.EOF {
fmt.Println("Load conf " + conf.File + " error: " + err.Error())
return
} else {
end = true
}
}
item := strings.Trim(line, "\n")
if item == "" {
continue
}
conf.Datas[item] = struct{}{}
}
}
</code></pre>
<p>But when I search key such like "www.google.com" in the map, it shows that there is not a "www.google.com" in the map.</p>
<pre><code>website := "www.google.com"
if _, ok := conf.Datas[website]; ok {
fmt.Printf("%s is in the map.", website)
} else {
fmt.Printf("%s is not in the map.", website)
}
</code></pre>
<p>It print "www.google.com is not in the map".
I found that a ^M in the end of each key in the map, my question is how can I remove the ^M character?</p>
<pre><code>www.google.com^M
www.apple.com^M
www.facebook.com^M

Why doesn't a generic NSDictionary warn me about incorrectly-typed key inserts/assignments? | <p>Why don't the following <code>NSDictionary</code>/<code>NSMutableDictionary</code> calls produce an error or warning?</p>
<p>I expect an error here because the rhs <code>NSDictionary</code> literal doesn't match the generic types of the <code>NSDictionary</code> lhs local variable.</p>
<pre><code>NSDictionary<NSString *, NSNumber *> *foo = @{ @(42) : @"foo" };
</code></pre>
<p>I expect an error here because the key type doesn't match the <code>NSMutableDictionary</code>'s key generic type:</p>
<pre><code>NSMutableDictionary<NSString *, NSNumber *> *foo = [NSMutableDictionary new];
// neither of these calls produces an error. :(
foo[@(42)] = @(42);
[foo setObject:@(42) forKey:@(42)];
</code></pre>
<p>I see an error when I try to assign an improperly-typed value, so I know generics errors are working somewhat:</p>
<pre><code>NSMutableDictionary<NSString *, NSNumber *> *foo = [NSMutableDictionary new];
foo[@"foo"] = @"bar";
</code></pre>
<p>Causes the following warning:</p>
<pre><code>Foo.m:81:16: Incompatible pointer types sending 'NSString *' to parameter of type 'NSNumber * _Nullable'
</code></pre>
<p>Why don't literal assignment or improperly-typed keys cause warnings/errors?</p>

Android Gradle compiling commons-io creates duplicate in library tree | <p>I'm trying to build and maintain an old application for work but I can't get past the build phase. In my <code>app/build.gradle</code> file I have </p>

compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.apache.commons:commons-io:1.3.2'

Using SQL as Session Cache in Azure | <p>I am currently looking for the best way to use session caching in an Azure Webservice. Because multiple Instances are used, standard asp.net Session state does not work.</p>
<p>I found some documents that this can be solved by using an external session state provider which allows using a shared cache (Redis cache) or SQL as an external provider.</p>
<p>But while I found a lot of documentations how to configure the Redis cache, I did not find a single example how to configure an Azure-SQL-Database for caching.</p>
<p>If this is still supported in Azure: Can you provide an example?</p> | 1 |

UI design for Microsoft Access - what is possible? | <p>I'm a graphic designer/web-UI designer by trade but have some (albeit limited) knowledge of Access. I haven't used it for a few years now but have been asked by a company to redesign the front end of their split database that was built using Access 2010. They had a programmer design the whole database, and it works well, but they do not like the actual appearance of the front-end so they have asked me to update it with some 'modern design' so-to-speak (i.e. stylise the buttons, fieds etc.)</p>
<p>I'm just wondering, what options do I have with this? Is there any way to use CSS as such to stylise the front-end? Or is there any built-in design tools that are useful? I plan to produce concepts using Photoshop to show them but it's knowing the limitations of what can be done with Access in terms of the front-end design. Any help would be appreciated!</p> | 1 |
Dynamically set install dir in WiX from environment variable | <p>I'm new to MSI development (with WiX or otherwise) and I'm trying to read the value of an environment variable and use it as the installation directory. My msi is gui-less too and giving the user to override the path is not permitted.</p>
<p>I can successfully read the var with:</p>
<pre><code><SetProperty
Id="TARGETINSTALLDIR"
Value="[%MY_ENV_VAR]\My\Install\Path"
After="LaunchConditions"
Sequence="first" />
</code></pre>
<p>I can see in the msi logs the correct path retrieved. </p>
<p>I have tried the following to set the returned path:</p>
<pre><code><Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="APPLICATIONROOTDIRECTORY" Name="[TARGETINSTALLDIR]"/>
</Directory>
</code></pre>
<p>Also,</p>
<pre><code><Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="APPLICATIONROOTDIRECTORY" Name="TARGETINSTALLDIR"/>
</Directory>
</code></pre>
<p>Failing that, I also tried to read the directory path within the ROOT Directory as shown below</p>
<pre><code><Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ROOT" Name="[%MY_ENV_VAR]">
<Directory Id="My" Name="My">

<p>I have the angularJS script <code>plotApp.js</code> as shown below, also very simple ...</p>
<pre><code>var app = angular.module('myApp', []);
app.controller('plotXY', function($scope, $http){
$scope.data = {};
$scope.refresh = function(){
$http.get('http://localhost:8080/data').success(function(data){

</code></pre>
<p>As you can tell, the portion within the <code>div</code> gets updates with the right data. However, that within the script doesn't! </p>
<p>Just so you know, If I use the <code>data</code> variable (the one that is commented out), I am able to see the plot. So Plotly is working.</p>
<p>I want the client to pull data from the server and have plotly display it. I can do it if I create the entire page from the server and send it over. However, I think that this way is much better. However, for some reason, I dont seem to be able to connect the data source in Plotly, to that in angularJS. I would really appreciate some help ...</p> | 1 |
Android using animation to make an object fall towards the ground using gravity | <p>I am new to Android development and I am trying to create an image at the top of the screen and make it fall to the bottom.

React how to remove listners correctly in componentWillUnmount, why do I need the bind in the constructor? | <p>I'm a bit confused, what is the difference between this sintax:</p>
<pre><code> constructor(props) {
super(props);
this.state = {
openPane: false
}
this.togglePaneHelper = this.togglePaneHelper.bind(this);
}
componentDidMount() {
document.body.addEventListener('click', this.togglePaneHelper);
}
componentWillUnmount() {
document.body.removeEventListener('click', this.togglePaneHelper);
}
</code></pre>
<p>and this one:</p>
<pre><code> constructor(props) {
super(props);
this.state = {
openPane: false
}
}
componentDidMount() {
document.body.addEventListener('click', this.togglePaneHelper.bind(this));
}
componentWillUnmount() {
document.body.removeEventListener('click', this.togglePaneHelper);
}
</code></pre>
<p>My concern is that the second syntax isn't removing correctly the listner and it cause this warning:</p>
<pre><code>Warning: setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the undefined component.

Explanation of the @ variables inside Rails models | <p>I've worked through a few Rails applications which are using @ attribute variables (which are already attr_accessible) in the models. I was having a tough time getting information on this but from what I gather <code>name</code> and <code>@name</code> are the same thing in a model but im probably incorrect on this. </p>
<p>How do these @ variables work and why would one ever use the @ symbol variables?</p> | 1 |
Braintree - What to post for paymentMethodNonce | <p>I am just getting started with Braintree and using it's API in PHP.</p>
<p>I have come across one thing, the "paymentMethodNouce" which is posted from the HTML file.</p>
<p>My question, is what does this need to include? I.e. do we post the send the credit card, billing information through here? And in what content does the form need to be in? I.e. Should it be like this:</p>
<pre><code> <form>
<input type="text" name="payment['creditcard']" value="124214124" />
<input type="text" name"payment['billingaddress']" value="12312313"/>
</form>
</code></pre>
<p>If this is not correct, what actually get's passed through to the <code>paymentMethodNonce</code> and how is the credit card details handled?</p> | 1 |

Location Reload Jasmine | <p>I got a problem with mocking the location reload functionality within Jasmine. I tried several methods (<a href="https://stackoverflow.com/questions/23344058/location-reload-in-jasmine">method 1</a> , <a href="https://stackoverflow.com/questions/27306194/mock-window-location-reload-in-jasmine-testing">method 2</a>) to mock any location reload events but with no luck. </p>
<p>My situation is the following thing. I have a rather simple function:</p>
<pre><code>function TestCall(xhr) {
if (xhr === 401) {
location.reload();
}
}
</code></pre>
<p>I tried creating the following Jasmine tests:</p>
<pre><code>it("FakeCall", function (){
spyOn(TestCall, 'reload').and.callFake(function(){});
TestCall(401);
expect(TestCall).toHaveBeenCalled(); // this should check if reload functionality have been called
});
</code></pre>
<p>I want to mock the location reload function but I have no clue why this does not work. Can anyone guide/tell me what I do wrong?</p>
<p>Total code:</p>
<pre><code>describe("multiple scripts", function () {
describe("2# FakeCall", function() {
function TestCall(xhr) {
if (xhr === 401) {
location.reload();
}
}
it("2.1 # Reload", function (){
spyOn(location, 'reload');
TestCall(401);
expect(location.reload).toHaveBeenCalled();
});

Vim - how to join lines using matching pattern | <p>I have a txt file that contains contact info for businesses. Currently, each line contains a different piece of data for the business. I'm attempting to construct a pipe-delimited file with all the info for each business on a single line. The catch is that there are a different number of lines for each business. So the file looks like this:</p>

</code></pre>
<p>etc.</p>
<p>So I can use <code>:g/<pattern>/j</code> to join lines within a pattern but I'm having trouble working out what the pattern should be. In the example above, lines 1-9 need to joined, and then lines 10-19.</p>
<p>The key is the lines that begin with 2 spaces and an asterisk:</p>
<pre class="lang-none prettyprint-override"><code> * Line of business
</code></pre>
<p>The pattern should basically say: "Starting with the first line beginning with a letter, join all lines until the first line after the last line beginning with <code>\ \ \*\</code>, then repeat until the end of the file."</p>
<p>How would I write this? Should I maybe do it in two steps - i.e., is there a way to first join all the lines starting with letters, then all the lines starting with <code>\ \ \*\</code>, then join each resulting pair?</p> | 1 |
Why does Rotativa always generate my login page? Why is it slow? | <p>I was using this Rotativa 1.6.4 code example to generate a PDF from a page in my .NET MVC 5 app.</p>
<pre><code>public ActionResult PrintIndex()
{
var a = new ActionAsPdf("Index", new { name = "Giorgio" }) { FileName = "Test.pdf" };
a.Cookies = Request.Cookies.AllKeys.ToDictionary(k => k, k => Request.Cookies[k].Value);
a.FormsAuthenticationCookieName = System.Web.Security.FormsAuthentication.FormsCookieName;
a.CustomSwitches = "--load-error-handling ignore";
return a;
}
public ActionResult Index(string name)
{
ViewBag.Message = string.Format("Hello {0} to ASP.NET MVC!", name);
return View();
}
</code></pre>
<p>It was not printing the Index page, but instead was printing my login page.</p>
<p>Once I fixed the authentication issue, PDF generation was extremely slow even with <code>CustomSwitches</code>. (Several minutes)</p>
<p>The above code might actually work for you - it got around the authentication issue using the <code>Cookies</code> property, but it was way too slow for me.</p>

"pause" for every host | <p>Before rolling updates I want to set downtime for every host in our monitoring tool. I created a custom module for this. There might be problems when setting downtime which can not be fixed on our end. In that case I want to give the user the choice to decide if the deployment should be aborted or continued without setting downtime.</p>
<p>So let's say I call my module like this:</p>
<pre><code>- downtime:
duration: 5m
comment: whatever
ignore_errors: true
register: downtime
</code></pre>
<p>So I'm ignoring the errors to be able to proceed. Otherwise hosts for which setting the downtime failed would not be processed any further.</p>
<p>In the next step I would like the user to manually confirm if he wants to proceed for every host that has no downtime set.</p>
<pre><code>- name: Request user confirmation to proceed in case downtime could not be set
pause:
prompt: 'Downtime could not be set for all hosts. Do you want to proceed? Press return to continue. Press Ctrl+c and then "a" to abort'
when: "{{ downtime | failed }}"
</code></pre>
<p>Unfortunately the <code>pause</code> module (actually it's an action plugin) would only pause for the first host that was processed. So if the first host failed, it will pause, if the first host passed and all other hosts failed it will simply continue with all hosts.</p>
<p>This seems to be the intended behavior. From the <a href="http://docs.ansible.com/ansible/pause_module.html" rel="nofollow">docs</a>:</p>
<blockquote>
<p>The pause module integrates into async/parallelized playbooks without any special considerations (see also: Rolling Updates). When using pauses with the <code>serial</code> playbook parameter (as in rolling updates) you are only prompted once for the current group of hosts.</p>
</blockquote>
<p>So no matter how, even if I would use <code>serial: 1</code> (which would not be possible in this case) pause would only stop for the first host.</p>
<p>Right now I simply pause without a condition and let the user decide if he wants to continue or not, no matter if the downtime task failed or not. But since the fails should be very rare this is a manual step I'd like to avoid.</p>
<p>Can anyone see a solution how to either:</p>
<ul>
<li>pause for <em>every</em> host (that failed)</li>
<li>pause once, in case <em>any</em> host failed</li>
</ul> | 1 |
Testing href value from a link component while having dynamic props | <p>I am looking for a solution in order to still be able to use Link from react-router instead of a when testing href attribute value.
Indeed, I have some components which change of route according to the context. However, when I am testing the href attribute value, the only thing returned is null.
However, when I use an a, it returns me the expected value.</p>
<p>Here is an failing test:</p>
<pre><code>import React from 'react';
import {Link} from 'react-router';
import TestUtils from 'react-addons-test-utils';
import expect from 'must';
const LINK_LOCATION = '/my_route';
class TestComponent extends React.Component {
render() {
return (
<div>
<Link className='link' to={LINK_LOCATION}/>
<a className='a' href={LINK_LOCATION}/>
</div>
);
}
}
describe('Url things', () => {
it('should return me the same href value for both link and a node', () => {
const test_component = TestUtils.renderIntoDocument(<TestComponent/>);
const link = TestUtils.findRenderedDOMComponentWithClass(test_component, 'link');
const a = TestUtils.findRenderedDOMComponentWithClass(test_component, 'a');
expect(link.getAttribute('href')).to.eql(a.getAttribute('href'));
});
});
</code></pre>
<p>Output: AssertionError: null must be equivalent to "/my_route"</p>
<p><em>knowbody</em> from React-router answered to see how they test Link, but they do not have dynamic context which can change value of the href attribute.</p>
<p>So I have done something like that: </p>
<pre><code>class ComponentWrapper extends React.Component {
constructor(props) {
super(props);
this.state = {};
}
set_props(props) {
this.setState({props});
}
render() {
if (this.state.props) {
return <Component {...this.state.props}/>;
}
return null;
}
}
</code></pre>
<p>But now, from my component helper: </p>
<pre><code>render_into_document() {
const full_component_props = {
location: this.location,
widget_categories: this.widget_categories
};
node = document.createElement('div');
this.component = render((
<Router history={createHistory('/')}>
<Route path='/' component={ComponentWrapper} />
</Router>
));
this.component.set_props(full_component_props);
return this;
}
</code></pre>
<p>I am not able to lay hand on <code>this.component</code> in order to changes props. How could I do that? </p> | 1 |
React Router (v3) redirect not redirecting to new location | <p>I have a router setup like this:</p>
<pre><code>import React from 'react';
import {IndexRoute, NotFoundRoute, Route, Redirect} from 'react-router';
import App from './components/app';
import Home from './components/Home';
import AuthorPage from './components/authors/AuthorPage';
import About from './components/about/About';
import NotFound from './components/NotFound';
const routes = (
<Route path="/" component={App} >
<IndexRoute component={Home} />
<Route path="about" component={About} />
<Route path="authors" component={AuthorPage} />
<Route path="*" component={NotFound} />
<Redirect from="/about-us" to="/about" />
</Route>
);
export default routes;
</code></pre>
<p>Everything but the redirecting works fine. Whenever I try to navigate to <code>/about-us</code>, I get a white page displaying <code>Cannot GET /about-us</code>.</p>
<p>Cannot seem to find anything about this in the docs. Does the "from" part of the route still have to exist for this to work, or should it just redirect me regardless?</p>
<p>EDIT:</p>
<p>I should also mention that I use the history package, as mentioned in the react-router upgrade guide: <code>https://github.com/rackt/react-router/blob/master/upgrade-guides/v1.0.0.md</code></p>
<p>Here is my main.js:</p>
<pre><code>import React from 'react';
import ReactDOM from 'react-dom';
import Router from 'react-router';
import routes from './routes';
import createBrowserHistory from 'history/lib/createBrowserHistory'
// Using history to avoid default behavior of weird urls like `?_k=umhx1s`
// See: https://github.com/rackt/react-router/blob/master/upgrade-guides/v1.0.0.md
let history = createBrowserHistory();
const root = document.getElementById('app');
ReactDOM.render(<Router history={history}>{routes}</Router>, root);

Suricata IPS manual blocking/unblocking vs. snort and guardian | <p>Does anyone have experience with using Suricata as an IPS? Im on Debian and I'd like to be able to manually block and unblock specific ip addresses (iptables). I've not used Suricata as I am currently running Snort as an IDS and guardian as my IPS. I've done a bit of research into Suricata and, as far as I can tell, one can manually add rules to Suricata's rule file which will block a given ip address. When Suricata is running as a daemon, do the block rules get wiped when you restart the daemon like they do with guardian?
Thanks in advance for any tips.</p> | 1 |

How to Deploy a jar onto Raspberry Pi 2 using Maven Plugin | <p>I have a simple java class using Pi4J that contains a main method. I want to build and deploy it to a Raspberry Pi. I'm using java 8 on a windows 10 and my IDE is NetBeans 8.1. If the project is set up to be a normal (non-Maven) Java Application and set up to deploy to the Raspberry Pi via the NetBeans build configurations as shown <a href="https://netbeans.org/kb/docs/java/javase-embedded.html" rel="nofollow">here</a>, the project will build normal and FTP over the jar and then run it with no issues.
I would like to do the same but using Maven. The problem is that the code that is being ran has C code native to the ARM's architecture of the Pi and the Maven plugin I'm using seems to run the jar on my local box first in which the C code will crash throwing the Exception</p>

<p>If i just do a clean build, it will build fine and create the jar. However, if i choose to run the build then thats where the crash happens. This is the Maven plugin I'm using to deploy the jar to the Pi.</p>

<p>I'm trying to figure out how to change this plugin to not execute the code first on my local machine. I just want it to assume the jar is built, ssh into the remote Pi and copy the jar over and then run it there. Also, if someone has a completely better way while using Maven then I'm open to suggestions. Any help would be great!</p>

calculate position of a point on image in percentage | <p>I am calculating position of a point on a image with the formula below in pixel, where oW is original image width and oH is original image height.</p>
<pre><code>var x = oW * parseInt(document.getElementById('pageX').value - $tagImage.offset().left - 5) / $tagImage.width();
var y = oH * parseInt(document.getElementById('pageY').value - $tagImage.offset().top - 5) / $tagImage.height();

Rails where not in array | <p>I have some posts that each has many tags.</p>
<p>I need to create a query that matches against the posts that are not having the exact tags as in an array.</p>
<p>Also it should return all the posts that are not having tags at all with that query.</p>
<p>Here is what I tried:</p>
<pre><code> query = posts.joins('LEFT JOIN post_tags ON post.id = post_tags.post_id')
no_tags = ['test', 'test1']
query = query.where('post_tags.name NOT IN (?) OR post_tags.name IS ?', no_tags, nil) if no_tags
</code></pre>
<p>This gives me all the posts that are having no tags at all which is correct, also it gives me the posts that haven't the tags specified, <strong>and no other tags</strong>, which is also correct.</p>
<p>The problem is that if a post has <strong>multiple</strong> tags, say <code>test, another</code>, it returns it in the query, which is not the behaviour I want.</p>
<p>I need to filter these posts out, if a post has a tag that is in the array, whether another tags are included or not.</p>
<p>Example:</p>
<pre><code>post1 has tag `test`
post2 has tag `another`
post3 has tags `test, another`
post4 has no tags
</code></pre>
<p>It should return:</p>
<pre><code>[post2, post4]
</code></pre>
<p>But now it returns:</p>
<pre><code>[post2, post3, post4]

What is best practice to communicate between React components and services? | <p>Instead of using flux/redux architecture, how react components should communicate with services?</p>
<p><strong>For example:</strong>
There is a container having few representational (react) components:</p>
<ol>
<li>ChatBox - enables to read/write messages</li>
<li>AvatarBox with password changer - which enables to change user's password</li>
<li>News stream - lists news and apply filter to them</li>
</ol>
<p>Thinking of them as resources representation, I want each of them to access Microservice API by itself (getting or updating data). Is this correct?
It will provide clean responsibility managing models, but it gives performance doubts using http requests to load each component's content</p>
<p>This question also reffers to: <a href="https://stackoverflow.com/questions/35286730/how-to-execute-efficient-communication-for-multiple-microservices">How to execute efficient communication for multiple (micro)services?</a></p> | 1 |

CakePHP 3 - Parse Date with LocalStringFormat to correct SQL format and correct validation | <p>we have declared the following lines in the initialize function of our AppController to have globally the same format for displaying dates:</p>
<pre><code> // default time formats on load
Time::$defaultLocale = 'de-DE';
Time::setToStringFormat('dd.MM.YYYY');
</code></pre>
<p>This worked fine. The date is displayed correcly in the view. But we get an validation error if we want to save the entity with the the date field (The provided value is invalid). The validator is configured like so:</p>
<pre><code> $validator
->add('datefield', 'valid', ['rule' => 'date'])
->allowEmpty('datefield');
</code></pre>
<p>Here a debug of the entity with the date field:</p>
<p>Before patchEntity:</p>
<pre><code>'datefield' => '08.07.2014'
</code></pre>
<p>After patchEntity:</p>
<pre><code>'datefield' => object(Cake\I18n\Time) {
'time' => '2014-07-08T00:00:00+0000',
'timezone' => 'UTC',
'fixedNowTime' => false
},
....
'[errors]' => [
'datefield' => [
'valid' => 'The provided value is invalid'
]
],
</code></pre>
<p>Is there a way to always parse the Date globally in the correct format for saving the entity and validation.</p> | 1 |
CUDA Installation for NVidia Quadro FX 3800 | <p>I'm having trouble installing CUDA 7.0 (to use with TensorFlow) on a workstation with the Nvidia Quadro FX 3800. I'm wondering if this is because the GPU is no longer supported.</p>

simple drawing with pyqt on a QGraphicsview | <p>I'm looking for a simple way to draw a line on a widget within a main window of a QT application.
I designed with QtDesigner a main window with a QGraphicsview and a button. When pressing a button, a line should be drawn in the graphics view. Isn't there a simple way to do so. Is a QGraphicsview the right choice for drawing? I read dozents of articles now and really found no solution.
Here is my code in short:</p>

from PyQt4.QtGui import *
class MainWindow(QMainWindow, mainwindowui.Ui_MainWindow):

self.setupUi(self)
self.connect(self.pushButton1, SIGNAL("clicked()"), self.pb1_pressed)
def pb1_pressed(self):
# here I want to draw a line on the QGraphicswidget:
# something simple like: graphview.line(x1,y1,x2,y2)

How to validate CronSequenceGenerator cron expressions? | <p>How could I validate <code>cron</code> expressions that are prepared for use of <code>CronSequenceGenerator</code>?</p>
<p>I mean, I cannot wait until the cron executes automatically as I'm defining like monthly intervals.</p>
<p>Is the following correct? How can I be sure?</p>
<pre><code>monthly at midnight: `0 0 0 1 * *`
monthly at 1 am: `0 0 1 1 * *`
weekly, on sunday at midnight: `0 0 0 * * SUN`

Rank Selection in GA? | <p>I have implemented <code>Roulette wheel selection</code> in <code>GA</code>.<br></p>
<pre><code> TotalFitness=sum(Fitness);
ProbSelection=zeros(PopLength,1);
CumProb=zeros(PopLength,1);
for i=1:PopLength
ProbSelection(i)=Fitness(i)/TotalFitness;
if i==1
CumProb(i)=ProbSelection(i);
else
CumProb(i)=CumProb(i-1)+ProbSelection(i);
end
end
SelectInd=rand(PopLength,1);
for i=1:PopLength
flag=0;
for j=1:PopLength
if(CumProb(j)<SelectInd(i) && CumProb(j+1)>=SelectInd(i))
SelectedPop(i,1:IndLength)=CurrentPop(j+1,1:IndLength);
flag=1;
break;
end
end
if(flag==0)
SelectedPop(i,1:IndLength)=CurrentPop(1,1:IndLength);
end
end
</code></pre>
<p><strong>Now i was trying to implement <code>rank selection</code> in <code>GA</code>. I learned that:</strong></p>
<ul>
<li><p>Rank selection first ranks the population and then every chromosome receives fitness from this ranking. </p></li>
<li><p>The worst will have fitness 1, second worst 2 etc. and the best will have fitness N (number of chromosomes in population). <br></p></li>
</ul>
<p><strong>I saw these <a href="https://stackoverflow.com/questions/9462350/differences-between-roulette-wheel-selection-and-rank-based-selection">link1</a> and <a href="https://stackoverflow.com/questions/20290831/how-to-perform-rank-based-selection-in-a-genetic-algorithm">link2</a> and what i understood is that:</strong></p>
<ol>
<li><p>First i will sort the Fitness value of the Population.</p></li>
<li><p>Then if the Population number is 10 then i will give the probability of selection to the Population like 0.1,0.2,0.3,...,1.0 .</p></li>
<li>Then i will calculate cumulative Fitness like roulette wheel.</li>
<li>And the next steps is same as roulette wheel.</li>
</ol>
<p><strong>My Implementation:</strong></p>
<pre><code> NewFitness=sort(Fitness);
NewPop=round(rand(PopLength,IndLength));
for i=1:PopLength
for j=1:PopLength
if(NewFitness(i)==Fitness(j))
NewPop(i,1:IndLength)=CurrentPop(j,1:IndLength);
break;
end
end
end
CurrentPop=NewPop;
ProbSelection=zeros(PopLength,1);
CumProb=zeros(PopLength,1);
for i=1:PopLength
ProbSelection(i)=i/PopLength;
if i==1
CumProb(i)=ProbSelection(i);
else
CumProb(i)=CumProb(i-1)+ProbSelection(i);
end
end
SelectInd=rand(PopLength,1);
for i=1:PopLength
flag=0;
for j=1:PopLength
if(CumProb(j)<SelectInd(i) && CumProb(j+1)>=SelectInd(i))
SelectedPop(i,1:IndLength)=CurrentPop(j+1,1:IndLength);
flag=1;
break;
end
end
if(flag==0)
SelectedPop(i,1:IndLength)=CurrentPop(1,1:IndLength);
end
end
</code></pre>

<strong>Am i understanding the algo wrong?? If it is then can anyone give me any idea how to modify my roulette wheel to rank selection??</strong></p> | 1 |

Securing Spring boot Rest services with CAS | <p>Friends,</p>
<p>Recently I have created one web-services application using spring-boot and now its having few unsecured entry points. (This is a pure rest based application having only rest entry points doesn't have any UI components).</p>
<p>Now I would like to add CAS client with this application for securing the rest entry points. </p>
<p>My CAS server is ready and its up and running. And I have configured CAS Rest protocol as well in my cas server to access TGT/ST through rest call and I'm in the planning of using only the rest call rather than using login pages.</p>
<p>So, when an user tries to access my rest application, I'm going to call CAS rest entry points internally (by using restTemplate) to validate user credentials and generating TGT and ST.</p>
<p>Available CAS entry points are (from jasig reference docs),</p>
<ol>
<li>POST /cas/v1/tickets HTTP/1.0
username=battags&password=password&additionalParam1=paramvalue</li>
<li>POST /cas/v1/tickets/{TGT id} HTTP/1.0
service={form encoded parameter for the service url}</li>
<li>DELETE /cas/v1/tickets/TGT-fdsjfsdfjkalfewrihfdhfaie HTTP/1.0</li>
</ol>
<p>I think, I'm little clear on this part. Please correct me if I'm wrong.</p>
<p>And now my query here is, <strong>what should I do to add a ST ticket validator in my spring boot application? Do I need to add any filters using spring-security? Or do I need to call any other rest api for validating the ST?</strong> Please guide me to proceed further.</p> | 1 |
How to save a standalone R environment object | <p>I am spending already hours trying to make this work and feel that I am missing something simple:</p>
<pre><code>my_env = new.env(hash = TRUE, parent = .GlobalEnv)
my_env[['echo']] <- function(x) {x}
my_env[['echo']](123)
[1] 123
my_env$echo(123)
[1] 123
save(my_env, file = "MyEnv.RData", envir = .GlobalEnv)
loaded_env <- load(file = "MyEnv.RData",envir = .GlobalEnv)
typeof(loaded_env)
[1] "character"
</code></pre>
<p>When I save entire workspace, functions are saved and then loaded back (after I close/open R Studio). But here, <code>save()</code> and/or <code>load()</code> do not work, and I have only a string in my environment after loading.</p>
<p>How could I save a separate environment object to a file, not a complete workspace? I then need all objects inside that environment (<code>my_env</code>) to be loaded into .GlobalEnv in another session. </p> | 1 |

What are the alternatives to eval in Ruby? | <p>I wrote the following recursive function in order to parse some settings and correctly populate some log file objects I have.</p>
<p>When I run this code against Code Climate it tells me that (of course) the use of <code>eval</code> is not encouraged. Is there a way I can rewrite this method so I do not need <code>eval</code> and also do not need a <code>case</code> statement? Nothing comes to mind.</p>
<pre><code>def parse(settings, logfile = nil)
settings.each do |key, value|
if value.is_a?(Hash)
logfile = Logmsg::LogFile.new
parse(value, logfile)
else
eval("logfile.#{key} = value")
end
end

how to disable DEBUG in log4j? | <p>need your help, I have log4j.properties like this</p>
<pre><code># Root logger option
log4j.rootLogger=stdout, file
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=${catalina.home}/logs/Admin.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

<p>and this is my Controller</p>
<pre><code>@SuppressWarnings("unused")
@RequestMapping(value="/addedc", method = RequestMethod.POST, consumes = "application/json", headers = "content-type=application/x-www-form-urlencoded")
public @ResponseBody Status_new addedc(@RequestBody installasimodel edc){
log.info("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< START ADDEDC >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
log.debug("qqqqqqqqqqqqqq");
List<installasimodel>mapusr = null;
try{
insta.addistlsi(edc);
log.info(new Status_new(1, "Sukses!"));
return new Status_new(1, "Sukses!");
}catch(Exception mapi){
log.info(new Status_new(0, mapi.getMessage()));
log.info("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< STOP ADDEDC >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
return new Status_new(0, mapi.getMessage());
}
}
