How to convert a Vagrantfile to a Dockerfile | <p>I'm trying to use the following Vagrantfile to make a Dockerfile for learning purposes. So far this is what I've come up with:</p>
<p>From Udacity: "Intro to Relational Databases", this is my Vagrantfile:</p>
<pre><code># -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.provision "shell", path: "pg_config.sh"
# config.vm.box = "hashicorp/precise32"
config.vm.box = "ubuntu/trusty32"
config.vm.network "forwarded_port", guest: 8000, host: 8000
config.vm.network "forwarded_port", guest: 8080, host: 8080
config.vm.network "forwarded_port", guest: 5000, host: 5000
end

Use VLC to fetch SDP file once using RTSP | <h2>Context</h2>
<ul>
<li>Most RTP streams (from e.g. an IP camera) need some information from a SDP to be able to decode them. </li>
<li>SDP is usually fetched just in time, usually from a RTSP URL but other means are possible (e.g. HTTP).</li>
</ul>
<h2>Specific case</h2>
<p>We have a situation where an RTP stream (from a camera, UDP sent at all time whether anyone listens or not) will be played using VLC, but providing VLC an RTSP URL to fetch SDP just in time is not an option. </p>
<p>There <em>is</em> a RTSP service yet we need to query it in advance and dump the resulting SDP file to feed it to VLC later. Doing a RTSP query just-in-time is useless anyway since the stream exists at all times.</p>
<h2>How to do that with VLC?</h2>
<h3>Search before you post</h3>
<p>Of course I've been searching Google, videolan wiki and StackExchange.</p>
<p>Information is difficult to find because when people talk about streaming, RTSP, RTP, they are generally usig VLC to <em>generate</em> a RTP stream, or output a SDP that VLC generates because it does the encoding, etc.
It's not the case here. The SDP to dump comes from the serveur with a single RTSP query.</p>
<h3>Question</h3>
<p>Basically, I'm looking for a command-line like:</p>
<pre><code>vlc --sout...something...rtsp://sourceIP:Port/...something...out...myfile.sdp
</code></pre>
<p>That would dump the SDP in <code>myfile.sdp</code>.</p>
<p>Then, later, running vlc with the <code>myfile.sdp</code> as argument is expected to play the stream.</p> | 1 |
Python Tools for Visual Studio Inline Graphics | <p>This one should be simple, but I've been searching all over and it seems to be so simple that nobody else has encountered the problem yet :)</p>
<p>I just installed Python (2.7 Anaconda distribution) and Python Tools for Visual Studio with Visual Studio 2015 Community. It all appears to be working, but I would like to use the inline graphics feature and can't get it to work. This code should (I think) do it, but instead shows nothing in the interactive window and pulls up a new blank window for the plot.</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
plt.ion()
X = np.linspace(-np.pi, np.pi, 256, endpoint=True)
C,S = np.cos(X), np.sin(X)
plt.plot(X,C)
plt.plot(X,S)
</code></pre>
<p>Do I need to configure something else before the inline graphics will work?</p> | 1 |
How to disable the navigation bar slide animation when going fullscreen? | <p>I have an activity that goes to another full screen activity. However, when transitioning from this activity to my full screen activity, the navigation bar slides down instead of disappearing instantly. I've inflated a full-screen window in the second activity, but because of the slow sliding animation, it resizes 1 second later after the animation has completed instead of being inflated to full-screen immediately. Therefore, I need the animation to disappear instantly. I've tried </p>
<p><code><item name="android:windowAnimationStyle">@null</item></code></p>
<p>and </p>
<pre><code>overridePendingTransition(0, 0);
</code></pre>
<p>and</p>
<pre><code>Transition fade = new Fade();
fade.excludeTarget(android.R.id.navigationBarBackground, true);
getWindow().setEnterTransition(fade);
</code></pre>
<p>with no luck. </p>
<p>On the Windows side, I've tried</p>
<pre><code>WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
WindowManager.LayoutParams.FLAG_FULLSCREEN
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN

How to label countries, not regions, using maps.text in the R maps package | <p>There don't appear to be any examples in the documentation for the maps package or on stack overflow of anyone trying to plot text or other information in place of a country name, rather than regions within a country.</p>
<pre><code>library(maps)
test <- structure(list(countries = structure(c(3L, 4L, 2L, 1L), .Label = c("France",
"Germany", "Italy", "UK"), class = "factor"), value = c(20, 13,
42, 6)), .Names = c("countries", "value"), row.names = c(NA,
-4L), class = "data.frame")
map.text("world", c("France", "Germany", "Italy", "UK"))

<p>I plan on replacing the country names with the values. The solution might look something like</p>
<pre><code>map.text("world",test$countries, labels=test$values)
</code></pre>
<p>but I can't figure out how to get it to leave out all the unnecessary region labels.</p> | 1 |

<pre><code>var req = http.request(options, function(res) {
res.setEncoding("utf8");
res.on("data", function (chunk) {
console.log(chunk);
});
});

::before
<div class="row">
::before
....

Python PyUSB HID Feature Report | <p>I am accessing a USB HID Device using python hidapi from a Mac OSX 10.10.5 doing:</p>
<pre><code>import hid
import time
hidraw = hid.device(0x1a67, 0x0004)
hidraw.open(0x1a67, 0x0004)
# Rpt, GnS, Tgt, Size, Index LSB, Index MSB, Data
# Blink 4 pulses
hidraw.send_feature_report([0x00, 0x00, 0x00,0x01, 0x01, 0x00, 0x03])
hidraw.get_feature_report(33,33)
time.sleep(3)
</code></pre>
<p>The HID Feature Report works nicely without problems.
However, I am trying to port this code to PyUSB and trying to do the same thing (on a RaspberryPi)</p>
<pre><code>import usb.core
import usb.util
# find our device
dev = usb.core.find(idVendor=0xfffe, idProduct=0x0004)
# was it found?
if dev is None:
raise ValueError('Device not found')
# get an endpoint instance
for interface in dev.get_active_configuration():
if dev.is_kernel_driver_active(interface.bInterfaceNumber):
# Detach kernel drivers and claim through libusb
dev.detach_kernel_driver(interface.bInterfaceNumber)
usb.util.claim_interface(dev, interface.bInterfaceNumber)
# set the active configuration. With no arguments, the first
# configuration will be the active one
dev.set_configuration()
ret = dev.ctrl_transfer(0x00, 0x00, 0x01, 0x01, [0x00, 0x03])
</code></pre>
<p>But I get a Broken Pipe when executed with root permissions. It is not very clear how to map the parameters that I used in the send_feature_report of Hidapi to how it is actually used from ctrl_transfer in PyUSB.</p>
<p>Any help on how this mapping should be made?</p>
<p>Thanks !!!</p>

Listening to the focus event in angular using $on | <p>I am using the swiper widget by <a href="http://www.idangero.us/swiper/#.Vqiziip96Uk" rel="nofollow">Idangero</a>, which allows me to pagify a form. However, since it loads all the controls up front, it is possible to tab into a field on the next page. I want to prevent this and I have found this <a href="https://jsfiddle.net/6rtskL5g/1/" rel="nofollow">jsfiddle</a> that changes the page when tabbing.</p>
<p>It, however, uses regular javascript to listen to the focus event <code>$('form')[0].addEventListener('focus'...</code> I want to convert this to a more angular version using the $rootscope.$on (I also want it to blur out of the field instead of changing the page, but I think I can handle that) anyone know how to do this?</p>
<p>I'd rather not use the ng-focus directive because then I have to add it to the controls at the bottom and top of every page.</p> | 1 |

Removing Big, old Files that do not belong in git | <p>Long story short, there are very big files (like iso files-big) that were pushed into git. Not during my time with the group, but they've been treating the repo like an SVN-VC. </p>
<p>Anywho, how can i removed iso's from the repo and its history, to lighten the repo.</p>

Is it possible to configure cucumber to run the same test with different spring profiles? | <p>I have an application where I'm running a trial with different technologies. I have a set of interfaces implemented with each technology and I use spring profiles to decide which technology to run. Each of the technologies has its own Spring java config annotated with the profile they are active for.</p>
<p>I run my cucumber tests defining which profile is the active one but this forces me to manually change the string every time I want to test a different profile, making it impossible to run automated tests for all of them. Is there anyway in cucumber to provide a set of profiles so tests are run once for each of them?</p>

C: Signal handling and semaphores | <p>I'm trying to better understand semaphores and all that jazz and for that I'm programming a server and clients that communicate using shared memory and semaphores. It works pretty well and everything, but I'm not sure I understand how signal handling properly works in this case. This is some sample code from my server. I realize it may be a bit redundant to check both, but I kinda would like to understand the weird behaviour I'm experiencing:</p>
<pre><code>sig_atomic_t running = 1;
while(running == 1) {
if (sem_wait(server) == -1) {
//exit and print error A
}
if(running == 0) {
//exit and print error B
}
/* do server stuff */
if (sem_post(client) == -1) {
//exit and print error
}
}
</code></pre>
<p>server is the server semaphore name, client is the client semaphore name (which doesn't really matter in this case). running (which is actually global) is the variable I use in my signal handler:</p>
<pre><code>static void init_signalhandler() {
struct sigaction sa;
sa.sa_handler = terminate;
if(sigemptyset(&(sa.sa_mask)) == -1) {
bail_out(EXIT_FAILURE, "sigemptyset error");
}
if(sigaction(SIGINT, &sa, NULL) == -1) {
bail_out(EXIT_FAILURE, "sigaction1 error");
}
if(sigaction(SIGTERM, &sa, NULL) == -1) {
bail_out(EXIT_FAILURE, "sigaction2 error");
}
}
static void terminate(int e) {
running = 0;
sem_post(server);
}
</code></pre>
<p>Where bail_out is a custom error printing/exiting function.</p>
<p>Basically no matter what I do, whenever I start up the server, it gets to the <code>sem_wait(server)</code> part. If I try to kill it by sending SIGINT, sometimes, it prints error A, and other times, it prints error B. This appears to be completely random. It kinda forces me to use the running variable though, since sometimes, the semaphore gets passed, while at other times, it does not.</p> | 1 |
Matlab interp2 extrapolation | <p>I am doing a 2-D interpolation using <code>interp2</code>. For some data values, the
interp2 command returns NaN because one of the dimensions are outside

there a way to do this for <code>interp2</code>?</p>

Paging is reset when data is updated with Angular-DataTables | <p>We have a Web form using Angular DataTables (DataTables 1.10.10 / angular-datatables - v0.5.3).

This is all working fine, when I select a different page from 1st one and the table get refreshed then paging is reset.

How to test in functional test if event has been dispatched | <p>I am testing a controller action using a functional test in Symfony. In this test I am doing something like this:</p>
<pre><code>$client->request(
'PUT',
'/api/nodes/',
$data
);
</code></pre>
<p>Afterwards I would like to test if a certain event has been dispatched. I already tried to enable the profiler previously (and set the config accordingly) and check the data in the <code>EventDataCollector</code>:</p>
<pre><code>$client->enableProfiler();
$client->request(
'PUT',
'/api/nodes/' . $data[0]['id'] . '?webspace=sulu_io&language=en',
$data[0]
);
/** @var EventDataCollector $eventDataCollector */
$eventDataCollector = $client->getProfile()->getCollector('events');
</code></pre>
<p>This works as expected, but the problem is that the <code>$eventDataCollector</code> only contains data about the events for which some listeners have actually been executed. Fortunately there is an event listener executed in this specific case, but I would like that to work also without any event listeners attached, since I can't say for sure that this situation will continue to be like that.</p>
<p>So my question is if there is a way to test if a event is dispatched, which is save, even if there wasn't a event listener attached.</p> | 1 |

NullValueHandling.Ignore influences deserialization into [ExtensionData] despite matching class member | <p>My server responses consists of a set of known and unknown properties. For the known ones, I created a DTO class with members for each property. The unknown properties shall be put inside a dictionary annotated with the <code>[ExtensionData]</code> attribute:</p>
<pre><code>[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
public class Dto
{
[JsonExtensionData]
private readonly Dictionary<string, object> unknownProperties = new Dictionary<string, object>();
public IDictionary<string, object> UnknownProperties
{
get
{
return new ReadOnlyDictionary<string, object>(this.unknownProperties);
}
}
[JsonProperty(Required = Required.Default, PropertyName = "KNOWN_PROPERTY")]
public string KnownProperty { get; private set; }
}
</code></pre>
<p><code>Null</code> is allowed as value for <code>KnownProperty</code>. If I try to deserialize a JSON object that contains <code>KNOWN_PROPERTY : null</code>, this property is also contained in the dictionary <code>UnknownProperties</code>, if I configure the serializer with <code>NullValueHandling.Ignore</code>. This is done even though a class member exists for <code>KNOWN_PROPERTY</code>:</p>
<pre><code>static void Main(string[] args)
{
string jsonString = @"{
KNOWN_PROPERTY : null,
UNKNOWN_PROPERTY : null
}";
JsonSerializer serializer = JsonSerializer.CreateDefault(new JsonSerializerSettings()
{
NullValueHandling = NullValueHandling.Ignore
});
using (var textReader = new StringReader(jsonString))
{
Dto dto = serializer.Deserialize<Dto>(new JsonTextReader(textReader));
foreach (var pair in dto.UnknownProperties)
{
Console.WriteLine("{0}: {1}", pair.Key, pair.Value == null ? "null" : pair.Value.ToString());
}
}
}
</code></pre>
<p>Output:</p>
<pre><code> KNOWN_PROPERTY : null
UNKNOWN_PROPERTY : null
</code></pre>
<p>If I configure the serializer with <code>NullValueHandling.Include</code> or set a value for <code>KNOWN_PROPERTY</code> in the JSON string, the dictionary contains only <code>UNKNOWN_PROPERTY</code>, as expected.</p>
<p>For my understanding <code>[ExtensionData]</code> is not working correctly if <code>NullValueHandling</code> is set to ignore, since the <a href="http://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_JsonExtensionDataAttribute.htm" rel="nofollow">documentation</a> states the extension is used only if no matching class member is found. </p>
<p>Is the behavior I'm seeing intended? Can I do something to avoid this? Because I don't like to send null values to the server, I'd like to stick to the currently set <code>NullValueHandling</code>.</p>

DownloadManager IllegalStateException creating a download in DIRECTORY_DOWNLOADS | <p>Firstly, there are a lot of questions on this subject, but none reflect my issue.

How to mock Auth in a Laravel 5.2 Model | <p>I'm trying to write some unit tests for a brand new mini app. I usually write functional tests so this is me branching out to try and do it properly with mocking and stubs and all those things that make it just about the code.</p>
<p>The model looks like this :</p>
<pre><code><?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Auth;
class myModel extends Model
{
public static function getUser()
{
$user = \Auth::user();
return $user->adldapUser->cn[0];
}
}
</code></pre>
<p>And the test :</p>
<pre><code>class MyModelTest extends TestCase
{
public function testGetUser()
{
$mockResult = new StdClass();
$mockResult->adldapUser = new stdClass();
$mockResult->adldapUser->cn=array("test");
$auth = $this->getMock('Auth');
$auth
->method('user')
->will($this->returnValue($mockResult));
$this->assertEquals('test',\App\MyModel::getUser());
}
}
</code></pre>
<p>But when I run the unit test I get the following error message :</p>
<p>There was 1 error:</p>
<blockquote>
<p>1) MyModelTest::testGetUser ErrorException: Trying to get property of
non-object</p>

Best way to detect editText inputType in Android? | <p>I developed a simple keyboard.</p>
<p>It's a T9 keyboard that is conceived specifically for phones with an hardware keyboard.</p>
<p>When I want to write something into a standard EditText I have no problem, but when i try to write numbers inside an ediText with <code>android:inputType="phone"</code> or <code>android:inputType="number"</code> the keyboard still tries to write letters.</p>
<p>My question is: What is the best and simplest way to detect if the editText I have focus on is Number-only, Text-only, etc. from my custom Keyboard?
How can I detect the inputType from my Keyboard?</p>
<p>I hope someone of you already solved this problem in the past and can help...thank you in advance! </p> | 1 |

How to display multiple strings into one Toast? | <p>I made some strings that I could display using a Toast but I'm having trouble figuring out how to make them appear at the same time as a single Toast. So far I have this:</p>

What does CommandLineRunner do in this case? | <p>I'm completely new to Spring & not very experienced in Java admittedly. I am trying to go through the <a href="http://spring.io/guides/tutorials/bookmarks/" rel="nofollow">Building REST services with Spring</a> tutorial on the spring.io website. I came across the following code segment and I'm confused as to what it actually does.</p>
<pre><code>@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {
@Bean
CommandLineRunner init(AccountRepository accountRepository,
BookmarkRepository bookmarkRepository) {
return (evt) -> Arrays.asList(
"jhoeller,dsyer,pwebb,ogierke,rwinch,mfisher,mpollack,jlong".split(","))
.forEach(
a -> {
Account account = accountRepository.save(new Account(a,
"password"));
bookmarkRepository.save(new Bookmark(account,
"http://bookmark.com/1/" + a, "A description"));
bookmarkRepository.save(new Bookmark(account,
"http://bookmark.com/2/" + a, "A description"));
});
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
</code></pre>
<p>I looked up CommandLineRunner on Spring Boot docs, and it says it's an interface that gets implemented if you want to execute some code when the application starts. But to my limited knowledge, CommandLineRunner is not getting implemented by anything in the above code segment. Also, I have no clue where the init() method came from or what it really is.</p>
<p>Additionally, I downloaded the complete code from their <a href="https://github.com/spring-guides/tut-bookmarks.git" rel="nofollow">github repo</a> but I'm not quite sure how to actually run it. I read earlier today that <code>SpringApplication.run()</code> makes it so that you don't have to deploy anything to an external service like Tomcat. But when I tried <code>java -jar ./jarFileName</code> for the Application class (seemed like a natural choice since it had main() ), it gave an error.</p>

BabylonJS, how to rotate mesh instead of the camera? | <p><a href="http://babylonjs-playground.com/#A83GX#0" rel="nofollow">http://babylonjs-playground.com/#A83GX#0</a></p>
<p>Hi All,</p>
<p>I have been playing with babylonjs for a couple of days now and excited about it. But why would I be here if I don't have a problem.</p>
<p>Attached the playground link, right now an arcrotatecamera rotates around a mesh. It gives an illusion that the mesh itself is being rotated, but when I move the object away from (0,0,0) it starts to show that the camera is rotating and not the object. Instead of such a camera hack, I would like to rotate the mesh itself from wherever it is, I googled and found a couple of topics in the babylonjs forum, but the solutions are not as smooth or eased as the camera solution. It will be great if someone can help me on this. Cheers and thanks for your help in advance.</p> | 1 |
Electron: Close w X vs right click dock and quit | <p>In my Electron app, I would like to do something that is done very often in other OSX apps. That is... I would like to NOT close the app of the red X is clicked in the top right. But, if they right click the app icon in the dock, and say Quit, then I would like to quit the app. How do I do this?</p>
<p>I have tried using the <code>onbeforeunload</code> event from the rendererProcess, as well as the <code>browserWindow.on("close", fn)</code> event to try and prevent this. The problem is that they both file the <code>onbeforeunload</code> event. And I can't tell the different between the red X being clicked and the dock icon being right clicked and told to quit. Any help would be nice. Has anyone else done this in Electron for OSX?</p> | 1 |

Iterating over columns and rows in pandas dataframe | <p>I am trying to iterate through a dataframe that I have and use the values inside of the cells, but I need to use the names of the columns and rows that the cells come from. Because of that I am currently doing something like the following:</p>
<pre><code>df=pandas.DataFrame(data={"C1" : [1,2,3,4,5], "C2":[1,2,3,4,5]},
index=["R1","R2","R3","R4","R5"])
for row in df.index.values:
for column in df.columns.values:
if (df[row][column] > 3:
if row in df2[column]:
print("data is present")
</code></pre>
<p>I need to use the row and column names because I am using them to look values up in another data frame that has related information. I know that for loops take forever in pandas, but I haven't been able to find any examples of how to iterate over both the row and the column and the same time. This: </p>
<pre><code>df.applymap()
</code></pre>
<p>wont work because it only gives the value in the cell, without keeping reference to which row and column the cell was in, and this:</p>
<pre><code>df.apply(lambda row: row["column"])
</code></pre>
<p>wont work because I need get the name of the column without knowing it before. Also this:</p>
<pre><code>df.apply(lambda row: someFunction(row))
</code></pre>
<p>wont work because apply uses a Series object which only has the row name, rather than the row and column names.</p>
<p>Any insight would be helpful! I am currently running the for loop version but it takes forever and also hogs CPU cores.</p> | 1 |

I also have a question about flash.now vs flash. Is that relevant in this case since the bookmark submission is an AJAX action?</p> | 1 |

Upload multiple files in ionic Cordova using one HTTP request | <p>I have seen ways to upload a file that originates from a <code><form> <input></code> but what I am trying to do in ionic is snap a photo using the camera plugin, then record audio using the media plugin and finally uploading both files in the same HTTP POST request. I know how to snap the photo and record the audio. I just need input on uploading both files in the same request. Anyone have insight how this can be done?</p> | 1 |
Send data through wifi (no internet) when mobile data on | <p>I'm developing and application that connects to a hardware device through wifi (generated by the device) and send data to it through a socket connection.
The problem is that when mobile data (3G/4G) is activated android tries to send the data through it instead of sending it through the wifi generated by the device, because because the wifi has no internet connection.
I was thinking of using <a href="http://developer.android.com/intl/pt-br/reference/android/net/ConnectivityManager.html#setNetworkPreference(int)" rel="noreferrer">ConnectivityManager#setNetworkPreference()</a> but it has been deprecated in api 21.</p>
<p>How can I set it to send data using the wifi generated by the device instead of the mobile data interface?</p> | 1 |
How to show different value of input element with ng-model? | <p>In the controller if have a variable that tracks the index (starting at 0) of the page for a pagination table:</p>
<pre><code>var page {
pageNumber: 0;
}
</code></pre>
<p>Question: how can I show this <code>pageNumber</code> variable in the html, but always incremented by +1? (as the index=0 page is obviously the 1st page and should thus be shown as <code>Page 1</code>)</p>
<pre><code><input type="text" ng-model="page.pageNumber">
</code></pre>
<p>Also, when the model gets updated, the value in the input should automatically change (again: also incremented by +1).</p> | 1 |
Can I pass variables using EventEmitter from angular2 component? | <p>I am new to angular2 so please excuse if I use the wrong terms in describing my problem.</p>
<p>I have a simple component that lets a user choose an option. Now I want to dispatch this option to the parent component. I am doing this:</p>
<pre><code>// import the necessary angular2 resources:
import {Component, Output, EventEmitter} from 'angular2/core';
...
// create the emitter in my component class:
export class MyClassThatLetsUserSelectSomeContentId{
@Output() selectEvent: EventEmitter<any> = new EventEmitter();
public selectedId: string;
// this does get called, showing the correct id in the console
onSelect(selectedItem: MyCustomItem){
this.selectedId = selectedItem.id;
console.log("selectedId:" + this.selectedId);
this.selectEvent.emit(this.selectedId);
}
}
</code></pre>
<p>and in the main component I include it in the template like this:</p>
<pre><code><my-selector-component (selectEvent)="onItemSelected(selectedItemId)"></my-selector-component>
</code></pre>
<p>And the function does get calles, but the variable is undefined:</p>
<pre><code>onItemSelected(selectedItemId: string){
console.log("onItemSelected(" + selectedItemId + ")");
}
</code></pre>
<p>the console output is:</p>
<p><em>log: onItemSelected(undefined)</em></p>
<p>So what am I missing? <strong>The event is sent and the function gets called but the parameter is lost</strong>.</p>
<p>Maybe some other form of binding to the selected Id would be better altogether. I am open to any kind of solution as long as the parent component can react to a new select from the view component.</p> | 1 |
How to connect to HTTP Rest API that authenticates with LDAP | <p>I am writing a Ruby script to connect to a REST API website.
The website is authenticated by using LDAP / SSO using the AD credentials, so no basic authentication or user/password has to be provided.</p>
<p>This is the code so far:</p>
<pre><code>resource_http = Net::HTTP.new(webserver.company.com, 443)
resource_http.use_ssl = true
resource_http.verify_mode = OpenSSL::SSL::VERIFY_NONE
resource_request = Net::HTTP::Post.new("/api/endpoint")
resource_request.set_form_data({"chocolate"=>"yes","beer"=>"yes"})
resource_response = resource_http.request(resource_request)
</code></pre>
<p>But I receive an authorization error:</p>
<pre><code>Net::HTTPUnauthorized 401 Authorization Required
</code></pre>
<p>Playing with Net::LDAP, I'm able to authenticate my credentials on my computer:</p>
<pre><code>ldap = Net::LDAP.new
ldap.host = "ldap.company.com"
ldap.port = "389"
ldap.auth "[email protected]", "password"
ldap.bind
</code></pre>
<p>But I have no idea how to "attach" or pass this LDAP info in the HTTP request.</p>
<p>All my Google searches point me to enabling SSO/authentication on a website app, but I'm not trying to do that, I want to connect with my Ruby script to an existing LDAP authenticated website.</p>
<p><strong>Update #1</strong>
Some Ruby forums pointed me to the gem HTTPI and using a 'curb' adapter. This adapter relies on the Curl library to handle the Kerberos/SPNEGO authentication.
However I was unable to make the curb installer work with the curl library they link on their website (for a Windows computer).</p>
<p>I moved the code to Python using the kerberos module. I'm able to generate the ticket and append it on the HTTP request headers, which get authenticated by the REST API and return the data I want.</p>
<p>I'm still learning, so even if my code works on Python I'd like to be able to make it work on Ruby.</p>
<p>Sample code in Python:
<a href="https://gist.github.com/DevOpsCow/d374300304d7beef8a03" rel="nofollow">https://gist.github.com/DevOpsCow/d374300304d7beef8a03</a></p> | 1 |
Calling node from a PHP script | <p>I'm trying to call a node script from a PHP script using <code>exec</code>:</p>
<pre><code>$output = exec("/usr/bin/node /home/user/nodescript.js");
</code></pre>
<p>The nodescript.js being:</p>
<pre><code>var Scraper = require('google-images-scraper');
var keywords = process.argv[2];
var scraper = new Scraper({
keyword: keywords,
rlimit: 10, // 10 p second
});
console.log("foo");
scraper.list(10).then(function (res) {
console.log("bar");
console.log(res);
});
setTimeout(function () {
process.exit(1);
}, 20000)
</code></pre>
<p>But what I receive is the string "foo", and not the "bar". If I run the node script from command line, I do get "foo" and "bar". Somehow I don't receive any console output inside the function. What am I doing wrong?</p> | 1 |

How to conditionally format highest value of multiple ranges | <p>I'm trying to use conditional formatting to highlight the maximum value over multiple ranges. That is, find the one highest value in said ranges and highlight all instances of it. I have been able to use conditional formatting to highlight the highest number of one column, but not over multiple.</p>
<p>The ranges in question are: <code>G3:G13,J3:J13,M3:M13,P3:P13,S3:S13,V3:V13</code></p>
<p><a href="https://i.stack.imgur.com/HBhvD.png" rel="nofollow noreferrer">Screenshot of the spreadsheet</a></p>
<p>The versions I have tried either highlight every value in the first row, multiple values but not the highest one, or nothing at all.</p>
<p>An alternative is to use a MAX function and place that value in another cell (the little 4 in the bottom right corner) and use conditional formatting based on that value. However, it's not a particularly elegant solution nor have I been able to make that work properly.</p>
<p>I am using New Google Sheets and am familiar with custom formatting and custom formulas for doing so.</p> | 1 |
Is it possible to create dynamic varchar2 variable? | <p>I have a function in PLSQL, that operates with strings and return VARCHAR2 type.</p>

Preprocess a Tensorflow tensor in Numpy | <p>I have set up a CNN in Tensorflow where I read my data with a TFRecordReader. It works well but I would like to do some more preprocessing and data augmentation than offered by the <code>tf.image</code> functions. I would specifically like to do some randomized scaling.</p>
<p>Is it possible to process a Tensorflow tensor in Numpy? Or do I need to drop the TFRecordReader and rather do all my preprocessing in Numpy and feed data using the feed_dict? I suspect that the feed_dict method is slow when training on images, but I might be wrong?</p> | 1 |
How do I programatically print to a label printer in windows 7 using C# | <p>I'm using Visual Studio 2013 (#C) and I have a SATO CL4NX label printer attached through a USB cable on Windows 7.

async task cancellation c# xamarin | <p>I have a functionality of search users. I have provided a textview and on that textview changed method I'm firing a method to get data from web server. But I'm facing problem when user types letter, because all the api hits done in async task. Service should be hit after 100 milli-sec of wait, means if user types a letter "a" then doesn't type for 100 milli-sec then We have to hit the service.

Android Event Bus Alternative | <p>Context: In a previous Android application I have developed, I used an <strong>event bus</strong> (<strong>otto</strong> by Square) to handle async task results (for example: the result of a server request is posted on the bus and somewhere in the application I intercept that response). Although it did the job, in some article I've read it was mentioned that using such a bus is rather a bad idea as it's considered an <strong>antipattern</strong>. </p>
<p>Why is that so? What are some alternatives to using an event bus when dealing with results of async operations? I know that, most of the time, there is no standard way to handle things, but is there "a more canonical" method? </p> | 1 |

PHPhotoLibrary getting album and photo info | <p>I am trying to get info on all the albums/photos using the PHPhotoLibrary. I barely know objective C, and i've looked at some tutorial/sample but couldn't find everything that I needed.</p>
<p>Here is a link to the sample code I based my code on.
<a href="https://developer.apple.com/library/ios/samplecode/UsingPhotosFramework/Introduction/Intro.html#//apple_ref/doc/uid/TP40014575-Intro-DontLinkElementID_2" rel="nofollow">https://developer.apple.com/library/ios/samplecode/UsingPhotosFramework/Introduction/Intro.html#//apple_ref/doc/uid/TP40014575-Intro-DontLinkElementID_2</a></p>
<p>So far I was able to get the albums name and identifier. And I am getting a list of photos, I am able to get their identifier as well, but not the filename. But if I put a break point in my fonction and look at my PHAsset pointer values, I can see the filename there (inside _filename), but if I try to call the variable with the filename in it, the variable does not exist.</p>
<p>So if anyone can provide a sample code to get all info on albums/photos/thumbnail that would be awesome. Or just getting the filename would be a good help.</p>
<p>Here is the code I have tried so far:</p>
<pre><code>-(void)awakeFromNib{
NSMutableArray *allPhotos = self.getAllPhotos;
for (int x = 0; x < allPhotos.count; x ++)
{
PHAsset *photo = [self getPhotoAtIndex:x];
PHAssetSourceType source = photo.sourceType;
NSString *id = photo.localIdentifier;
NSString *description = photo.description;
NSUInteger height = photo.pixelHeight;
NSUInteger width = photo.pixelWidth;
NSLog(@"Test photo info");
}
}
-(PHAsset*) getPhotoAtIndex:(NSInteger) index
{
return [self.getAllPhotos objectAtIndex:index];
}
-(NSMutableArray *) getAllPhotos
{
NSMutableArray *photos = [[NSMutableArray alloc] init];
PHFetchOptions *allPhotosOptions = [[PHFetchOptions alloc] init];
allPhotosOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]];
PHFetchResult *allPhotos = [PHAsset fetchAssetsWithOptions:allPhotosOptions];
PHFetchResult *fetchResult = @[allPhotos][0];
for (int x = 0; x < fetchResult.count; x ++) {
PHAsset *asset = fetchResult[x];
photos[x] = asset;
}
return photos;
}

Highcharts - Line chart is using wrong TimeZone | <p>I have a situation where I need to display the exact time received from server in the Highchart. The datetime should not change based on either server timezone or client timezone.</p>
<p>I have set the UTC to true:</p>
<pre><code>Highcharts.setOptions({
global: {
useUTC: true,
timezoneOffset: 0
}
});
</code></pre>
<p>And I am passing the Milliseconds as data:</p>
<pre><code> for (i = 0; i < xAxisData.length; i++) {
item = xAxisData[i];
dateMiliseconds = parseInt(item.DateTime.replace('/Date(', ''));
var obj = { x: dateMiliseconds, title: item.FlagText, text: item.Text };
xData.push(obj);
}
</code></pre>
<p>then setting the series like this:</p>
<pre><code> $scope.chartConfig.series.push({
type: 'flags',
data: xData,
onSeries: 'mileageSeries',
shape: 'squarepin',
name: 'Events',
title: 'Events',
id: "Events"
//width: 16
});
</code></pre>
<p>Now everything works fine if I have server with UTC date time system settings.</p>
<p><a href="https://i.stack.imgur.com/7Q3Ai.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7Q3Ai.png" alt="enter image description here"></a></p>
<p>But when I have a server with UTC + 5 date time system settings the graph is wrong:</p>
<p><a href="https://i.stack.imgur.com/4QlBk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4QlBk.png" alt="enter image description here"></a></p>
<p>What I need is no matter what the server timezone is and no matter what the Client side timezone is it should display <code>7:42</code>. 7:42 time is sent from the server in both cases the data is same:</p>
<pre><code> DateTime: "/Date(1453776133000)/"
DateTimeString: "26/01/2016 07:42:13"

Java 8: How to parse expiration date of debit card? | <p>It is really easy to parse expiration date of debit/credit card with Joda time:</p>
<pre><code>org.joda.time.format.DateTimeFormatter dateTimeFormatter = org.joda.time.format.DateTimeFormat.forPattern("MMyy").withZone(DateTimeZone.forID("UTC"));
org.joda.time.DateTime jodaDateTime = dateTimeFormatter.parseDateTime("0216");
System.out.println(jodaDateTime);
</code></pre>
<p>Out: <code>2016-02-01T00:00:00.000Z</code></p>
<p>I tried to do the same but with Java Time API: </p>
<pre><code>java.time.format.DateTimeFormatter formatter = java.time.format.DateTimeFormatter.ofPattern("MMyy").withZone(ZoneId.of("UTC"));
java.time.LocalDate localDate = java.time.LocalDate.parse("0216", formatter);
System.out.println(localDate);
</code></pre>
<p>Output:</p>

Validate reCAPTCHA in bootstrap modal using ajax | <p>We have a reCAPTCHA witch loads on bootstrap modal opening at <a href="http://jsfiddle.net/emilhem/Lgovn28f/4/" rel="nofollow">HERE</a>.
There is not any form to submit. I just want to validate reCAPTCHA when user checked the reCAPTCHA using ajax request. In other words, how to recognize (using javascript) when user checked the reCAPTCHA and after it validate reCAPTCHA from server side (for example validate.php) using an ajax request?

Date/Datetime as uint in wrapped api | <p>I am using a wrapper of a C++ api which isn't really documented. Some of the exposed methods require fields (from and to) which are of type uint. The fields are actually datefrom and dateto, but the types aren't as such. I have tried different approaches, including converting datetime to DOS unsigned int representation</p>
<pre><code> public ushort ToDosDateTime( DateTime dateTime)
{
uint day = (uint)dateTime.Day; // Between 1 and 31
uint month = (uint)dateTime.Month; // Between 1 and 12
uint years = (uint)(dateTime.Year - 1980); // From 1980
if (years > 127)
throw new ArgumentOutOfRangeException("Cannot represent the year.");
uint dosDateTime = 0;
dosDateTime |= day << (16 - 16);
dosDateTime |= month << (21 - 16);
dosDateTime |= years << (25 - 16);
return unchecked((ushort)dosDateTime);
}
</code></pre>
<p>, but still the api function call returned nothing if not an error.
, I also tried the plain representation as : 20160101 which made sense but didn't succeed.
Is there a known way of representing dates and times as unsigned integers?</p> | 1 |
How to setup signtool with SHA256 on Windows 7? | <p>I have been using SHA1 signing for many years, but from 2016, Windows is forcing developers to use SHA256.</p>
<p><a href="http://social.technet.microsoft.com/wiki/contents/articles/32288.windows-enforcement-of-authenticode-code-signing-and-timestamping.aspx" rel="nofollow noreferrer">Windows Enforcement of Authenticode Code Signing and Timestamping</a></p>
<p>By using Windows 7 SDK signtool the functions to sign SHA-256 is "unknown commands", so this signtool is obsolete as a signtool and shouldn't be used any more.</p>
<p>To sign with SHA256 I downloaded the Windows 8.1 SDK to get signtool.exe which got the new functions(/fd and a few others). The BAT file and signtool works on Windows 8 and 10, so I know it works, but crashes on Windows 7 when it tries to timestamp the file.</p>
<p><a href="https://i.stack.imgur.com/V8o72.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/V8o72.png" alt="enter image description here" /></a></p>
<p>I use a bat file to sign files, which looks like this(I edited the BAT file so it doesn't show variables, full paths, company name and passwords):</p>
<pre><code>Path\signtool.exe sign /f "Path\Certificate.p12" /fd sha256 /p *password* /du "URL" /tr "timestampServer?td=sha256" /td sha256 /d "Product name" "Filename"
</code></pre>
<p>I guess, I don't have the proper SDK to support some of the functions, but I can't find any info on the internet on how to setup this on a Windows 7. I tried to install MS Visual C++ 2015 Redistributable (x64) on my machine without solving the problem.</p> | 1 |
Matlab ShortEng number format via sprintf() and fprintf()? | <p>I like using MATLAB's <code>shortEng</code> notation in the interactive Command Window:</p>
<pre><code>>> a = 123e-12;
>> disp(a);
1.2300e-10 % Scientific notation. Urgh!
>> format shortEng;
>> disp(a);
123.0000e-012 % Engineering notation! :-D
</code></pre>
<p>But I want to use fprintf:</p>
<pre><code>>> format shortEng;
>> fprintf('%0.3e', a);
1.2300e-10 % Scientific. Urgh!
</code></pre>
<p>How do I print values with fprintf or sprintf with Engineering formatting using the MATLAB <a href="http://uk.mathworks.com/help/matlab/ref/fprintf.html#inputarg_formatSpec" rel="nofollow">Format Operators</a>? </p>
<p>I know I could write my own function to format the values into strings, but I'm looking for something already built into MATLAB.</p>
<p>NOTE: "Engineering" notation differs from "Scientific" in that the exponent is always a multiple of 3.</p>
<pre><code>>> fprintf('%0.3e', a); % This is Scientific notation.

How many is too many for create dispatch_queues in GCD (grand central dispatch)? | <p>There is a wonderful article about a lightweight notification system built in Swift, by Mike Ash: (<a href="https://www.mikeash.com/pyblog/friday-qa-2015-01-23-lets-build-swift-notifications.html" rel="noreferrer">https://www.mikeash.com/pyblog/friday-qa-2015-01-23-lets-build-swift-notifications.html</a>).</p>
<p>The basic idea is you create objects that you can "listen" to i.e. invoke a callback on when there is some state change. To make it thread-safe, each object created holds its own dispatch_queue. The dispatch_queue is simply used to gate critical sections:</p>
<pre><code>dispatch_sync(self.myQueue) {
// modify critical state in self
}
</code></pre>
<p>and moreover it likely won't be in high contention. I was kind of struck by the fact that <em>every</em> single object you create that can be listened to makes its own dispatch queue, just for the purposes of locking a few lines of code.</p>
<p>One poster suggested an OS_SPINLOCK would be faster and cheaper; maybe, but it would certainly use a lot less space.</p>
<p>If my program creates hundreds or thousands (or even tens of thousands of objects) should I worry about creating so many dispatch queues? Probably most won't ever even be listened to, but some might.</p>
<p>It certainly makes sense that two objects not block each other, i.e. have separate locks, and normally I wouldn't think twice about embedding, say, a pthread_mutex in each object, but an entire dispatch queue? is that really ok?</p> | 1 |
Switching and focusing a newly opened tab in selenium | <p>Hello I am using selenium to click links and generally use an online web app.</p>
<p>I have trouble when I click a particular link which opens a new tab and performing an action in that newly opened tab. I have this code:</p>
<pre><code>friend_link = browser.find_element_by_tag_name('a')
friend_link.click() # this is where new tab is opened
</code></pre>
<p>After which the webdriver(from my eyes) opens to the new tab without me having to call</p>
<pre><code>browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)
</code></pre>
<p>So all is good. New tab is opened on the webdriver. When I try to click a link on that newly opened tab, I get a 'No element' exception, meaning it couldn't find the element I was looking for.</p>
<p>Two questions:</p>
<p>1) Does the webdriver know that a newly opened tab was opened and to perform actions on that tab? Maybe I have to tell it. I tried</p>
<pre><code>main_window = browser.current_window_handle
browser.switch_to_window(main_window)
</code></pre>
<p>which is supposed to refocus a newly opened tab, but no luck.</p>
<p>2) Is there a way to see if the computer knows that it's on the new tab?</p> | 1 |
Handling Angular 2 http errors centrally | <p>I have some code that handles all http access in a class that handles adding tokens. It returns an Observable.

How to map NaN in numpy to values using dictionary? | <p>I have a dictionary that maps numeric values to labels. I use it to create labels for a given numpy array. The array initially contains all NaN values and some elements get populated with non-NaN values. I want to map NaN values to a label. However, this fails:</p>
<pre><code>import numpy as np
# make array with all NaNs
a = np.ones(5) * np.nan
# populate some of it with non-NaN values
a[0] = 1
a[1] = 2
l = {"1": "one", 2: "two", np.nan: "NA"}
for k in l:
if k == np.nan:
print l[k]
# this returns false
print (np.nan in a)
</code></pre>
<p>Is this because of the initialization of the array? Why is <code>np.nan</code> not equal to the NaN values in <code>a</code>?</p>
<p>I am trying to get a working version of:</p>
<pre><code>print l[a[3]] # should print "NA", not raise keyerror
</code></pre> | 1 |

Generate a token for email verification in CodeIgniter 3 | <p>I'm building a login/reg system in CI3 and I have a doubt.
Instead of use:</p>

</code></pre>
<p>for sending key for email activation...can I use another method? I don't know, using database (mysql)? hash with SHA1 maybe?
I don't want the most secure way, just a solution that is not fake as uniqid() is. 'Cause I know that id generated by uniqid() is not really random, so there is no reason to hash to md5 is simply...stupid.</p>

Camel Mock test using file as input | <p>I want to create a Mock Test for a Camel route which uses as input a file:</p>

Get full result back from PeeWee query (for conversion to JSON) | <p>I am trying to render a PeeWee query result as <code>JSON</code> using the following code:</p>
<pre><code>@app.route('/')
def index():
c = Category.select().order_by(Category.name).get()
return jsonify(model_to_dict(c))
</code></pre>
<p>Doing this I only get one row back from the query. I'm pretty sure the issue is my use of <code>get()</code>, which the docs clearly say only returns one row. What do I use in place of <code>get()</code> to fetch the <em>entire</em> results back?</p>
<p>This question below pointed me in the right direction, but is is also using <code>get()</code></p>
