d7701 | train | Enter the code here. Discord has added a feature (or it was already there, I don't know), which enables you to do what you want to do.
const data = b64image.split(',')[1];
const buf = new Buffer.from(data, 'base64');
const file = new Discord.MessageAttachment(buf, 'img.jpeg');
const embed = new Discord.MessageEmbed()
.attachFiles(file)
.setImage('attachment://img.jpeg')
webhookClient.send('', {
username: userName,
embeds: [embed],
});
A: I tried with a smaller image, and the code in the question worked. So it was a problem with the size of the request.
I fixed it by setting up an express route to serve images and used the URL in the embed
router.get('/thumb/:imgId', (req, res) => {
const imgId = req.params.imgId.toString().trim();
let file = Buffer.from(b64Image.split(',')[1], 'base64')
res.status(200);
res.set('Content-Type', 'image/jpeg');
res.set('Content-Length', file.length)
res.send(file)
});

d7702 | train | To augment the correct answers to use math.acos, it is also worth knowing that there are math functions suitable for complex numbers in cmath:
>>> import cmath
>>> cmath.acos(1j)
(1.5707963267948966-0.88137358701954294j)
Stick with math.acos if you're only interested in real numbers,
A: The result of math.acos() is in radians. So you need to convert that to degrees.
Here is how you can do:
import math
res = math.degrees (math.acos (value))
A: We have the acos function, which returns the angle in radians.
>>> import math
>>> math.acos(0)
1.5707963267948966
>>> _ * 2 - math.pi
0.0
A: In response to using inverse cosine to find return angles via math.acos, it's all fine and dandy so long as the angle is <=90* once you go past that, python will have no way of differentiating which angle you wanted.
Observe.
>>> math.cos(5)
0.28366218546322625
Above, I asked python to fetch me the cosine of a 5 radian angle, and it gave me .28~ Great, below I'll ask python to give me the radian which has a .28~ cosine. Should be 5, right? It literally just told me it was.
>>> math.acos(0.28366218546322625)
1.2831853071795865
Wrong! Python returns 1.28~ radians. The reason is obvious when plotted visually, 1.28rad has the same cosine as 5rad, they're inverse angles. Every angle shares the same sine with another angle (and -sine with two others).
i.e. 5/175* share an equivalent sine. They share inversely proportional cosines .99~/-.99 respectively. Their -sine cousins would be 185 and 355. The relationship meme here is that all these angles share the same angular deflection from the horizontal axis. 5*.
The reason python returns 1.28 and not 5 is that all computers/calculators are based on an abacus-like data table of an angle/radian, its sine, cos, tan etc etc. So when i math.acos(x), python asks the kernal to look through that data table for whichever angle has a cosine of x, and when it finds it, it returns the first entry it appears with. and then python gives that angle to me.
Due to this shared, proportional symmetry, sin/cos ratios repeat frequently. And you are likely to see the same figure, multiple times. There's no way for python, or the OS, to determine the difference of which of the two angles you actually require without doing additional logic that takes into account the -/+ value of the angle's sine. Or, the angle's tangent.
1.28 Rad has x cosine, y sine, z tan (72*)
1.88 Rad has -x cosine, y sine, -z tan (108*)
4.39 Rad has -x cosine, -y sine, z tan (252*)
5 Rad has x cosine, -y sine, -z tan (288*)
or, viewed Cartesianly,
negX,posY | posX,posY
-----+-----
negX,negY | posX,negY
1.88 Rad has -x cosine, y sine (108) | 1.28 Rad has x cosine, y sine (72*)
-----+-----
4.39 Rad has -x cosine, -y sine (252)| 5 Rad has x cosine, -y sine (288)
So if, for whatever reason, i need 5 radians to be chosen (say for a vector drawing or game to determine the various vectors enemies are from the player), i would have to do some type of if/then logic comparing the sines/tangents.
A: You're looking for the math.acos() function.
A: You may also use arccos from the module numpy
>>> import numpy
>>> numpy.arccos(0.5)
1.0471975511965979
WARNING: For scalars the numpy.arccos() function is much slower (~ 10x) than math.acos. See post here
Nevertheless, the numpy.arccos() is suitable for sequences, while math.acos is not. :)
>>> numpy.arccos([0.5, 0.3])
array([ 1.04719755, 1.26610367])
but
>>> math.acos([0.5, 0.3])

d7705 | train | You could just remove these 0s using conditional indexing (also assumed you meant len(l) - 1):
a= torch.randperm(len(l)-1) #where l is total no of testing image in dataset, code output->tensor([10, 0, 1, 2, 4, 5])
a=a[a!=0]
b=torch.tensor([0]) # code output-> tensor([0])
c=torch.cat((b,a))# gives output as -> tensor([0, 10, 0, 1, 2, 4, 5]) and 0 is used twice so repeated test image
Or if you want to make sure it's never put in:
a=torch.arange(1,len(l))
a=a[torch.randperm(a.shape[0])]
b=torch.tensor([0])
c=torch.cat((b,a))

d7706 | train | No, but it's quite simple to implement, you only need a linear layout with horizontal orientation, containing a button, a textview and another button.
Have an internal value to count and then associate a callback to your buttons, where you add/substract your counter and update the textview, like this:
substractButton.setOnClickListener(v -> {
count--;
countTextView.setText(count);
});
sumButton.setOnClickListener(v -> {
count++;
countTextView.setText(count);

d7709 | train | I ran into the same error using Rails and RSpec to test an API. I found a helpful blog post for Rails 2.3: http://eddorre.com/posts/using-rack-test-and-rspec-to-test-a-restful-api-in-rails-23x
module ApiHelper
require 'rack/test'
include Rack::Test::Methods
def app
ActionController::Dispatcher.new
end
end
My solution for Rails 3.2 was (look in config.ru for MyAppName):
module ApiHelper
require 'rack/test'
include Rack::Test::Methods
def app
MyAppName::Application
end
end
A: try this
def app
Rails.application
end
A: For anyone else banging their heads against the wall getting the "NameError: undefined local variable or method `app'" error. It also happens when you are running all your tests at once (multiple files) and one of them does an include Rack::Test::Methods - the include "infects" the other tests. So the symptom is that all tests pass when the files are run individually, but then they fail with the "no app" error when run together. At least this happens with rails 3.0.9 and rspec 3.0
The solution to this issue is to remove the includes. Alternatively you might try something like @ultrasaurus' answer to make sure the includes are properly contained to only the examples that need it. | unknown | |

d7714 | train | If you really, really must do this, and you are sure you are not making a mistake, check out the @SuppressWarnings annotation. I suppose in your case you need
@SuppressWarnings("fallthrough")
A: Is the annotation @SuppressWarnings (javadoc) what you are looking for?
For example:
@SuppressWarnings("unchecked")
public void someMethod(...) {
...
}
A: To complete other answer about SuppressWarnings:
@SuppressWarnings("fallthrough")
Try to supress all the fall-through warning at the compiler level is a bad thing: as you've explained, the cases where you need to pass through the warning are clearly identified. Thus, it should be explicitly written in the code (the @SuppressWarnings("fallthrough") annotation with an optionnal comment is welcome). Doing so, you'll still have the fall-through warning if you really forget a break somewhere elese in your code.
A: You could create a structure of 'if' statements in place of the switch. Might not be as visually pleasing however neither is warning supression.
A: @SuppressWarnings("fallthrough")
Java has always followed the C-style of switch statements, where you need to explicititly break out of a switch unless you wish to simply fall through and execute the code in the case below. This can be dangerous of course and errors of this kind can be very hard to track down. In the following example, case 1 lacks a break:
@SuppressWarnings("fallthrough")
public void fallthroughTest(int i)
{
switch (i)
{
case 1:
// Execute both 1 and 2
case 2:
// Execute only 1
}

d7716 | train | this might help you.
Would be better if we could use Stream<char>, but, this does not work, so, we need to use the wrapper class.
Since you want the first index, you can use 0.
String.charAt(index) returns a char primitive, so, it will use less memory than a String.substring(...) that returns a new String.
final String[] array = {"A", "B", "C", "D"};
final Character [] char_array = Arrays.stream(array)
.map(s -> s.charAt(0))
.toArray(Character[]::new);
for(char a: char_array) {
System.out.println(a);
}
A: You can use streams, this will return a char [] array.
Arrays.stream(S).map(s -> s.substring(0,1)).collect(Collectors.joining()).toCharArray();
Full code
String [] S = { "A", "B", "C"} ;
char [] ch =Arrays.stream(S).map(s -> s.substring(0,1))
.collect(Collectors.joining()).toCharArray();
for(int i=0;i<ch.length;i++){
System.out.println(ch[i]);
}
For better use, I suggest making a method that implements this stream and returns a char []
public char [] convertToChar(String [] yourArray){
return Arrays.stream(youArray).map(s -> s.substring(0,1)).collect(Collectors.joining()).toCharArray();

d7718 | train | I've taken a look at your code and altered it. Try this and see if this is what you're looking for.
In my example i'm looking for the element by getElementById and then I set it's style.height to window.innerHeight - 10px without taking the 10px it wouldn't show the border fully on the page. So you just remove 10px's. The example has been tested on different screen sizes.
Javascript example:
function autoResizeDiv() {
document.getElementById('body').style.height = window.innerHeight - 10 + 'px';
console.log(window.innerHeight - 10 + 'px');
}
window.onresize = autoResizeDiv;
autoResizeDiv();

A: The following worked for me:
$(".body").height($(window).height());
A: I figured out the biggest problem. I was using some absolutely positioned elements without giving a parent any other position. This made things show up wonky when I was trying to size other things. I also needed to have an extra div as a container for all the content on the page that would be the height of the window + the height of the header.
Thanks to everyone who answered, it helped! | unknown | |
d7719 | train | You can type the data prop as RnMcharacter.
You can also remove the then call as you're using async|await
export async function askForList(){
const res = await fetch('http://127.0.0.1:3333/applist');
const { data }: { data: RnMcharacter } = await res.json();
return data;

d7720 | train | I had a similar problem earlier. I hope this will work for you. As I did not have your data, I created some dummy data. Sorry about the looooong explanation. Here are the steps that should help you reach your goal...
This is what I did:
*
*Order the data and sort it - used pd.Categorical to set the order and then df.sort to sort the data so that the input is sorted by source and then destination.
*For the sankey node, you need to set the x and y positions. x=0, y=0 starts at top left. This is important as you are telling plotly the order you want the nodes. One weird thing is that it sometimes errors if x or y is at 0 or 1. Keep it very close, but not the same number... wish I knew why
*For the other x and y entries, I used ratios as my total adds up to 285. For eg. Source-Informal starts at x = 0.001 and y = 75/285 as Source-Formal = 75 and this will start right after that
*Based on step 1, the link -> source and destination should also be sorted. But, pls do check.
Note: I didn't color the links, but think you already have achieved that...
Hope this helps resolve your issue...
My data - sankey.csv

d7723 | train | It happens because you have to specify urlRoot property of the model. Without it url is not considered. So try this maybe:
MessageManager.models.Conversation = Backbone.Model.extend({
defaults: {
uid: '',
title: '',
messages: [],
users: [],
dateUpdated: null,
isNew: true,
message: ''
},
urlRoot: function() {
var url = '/api/conversations';
if (this.get('uid').length > 0) url += '/'+this.get('uid');
return url;
}
});
Documentation says:
urlRootmodel.urlRoot or model.urlRoot()
Specify a urlRoot if you're using a model outside of a collection, to enable the default url function to generate URLs based on the model id. "[urlRoot]/id"
Normally, you won't need to define this. Note that urlRoot may also be a function.
And source code for Backbone.Model url method:
url: function() {
var base =
_.result(this, 'urlRoot') ||
_.result(this.collection, 'url') ||
urlError();
if (this.isNew()) return base;
return base.replace(/([^\/])$/, '$1/') + encodeURIComponent(this.id);
},
A: defsq answer is good. The only thing missing is to define the idAttribute on your model, since it's not the convention-based id field, but uid.
MessageManager.models.Conversation = Backbone.Model.extend({
idAttribute: 'uid',
defaults: {
uid: '',
title: '',
messages: [],
users: [],
dateUpdated: null,
isNew: true,
message: ''
},
urlRoot: "/api/conversations"
});
You don't need to append the "id" manually. Just tell Backbone that your id attribute is uid and everything else will work. In fact, you can event call mymodel.id to get the id of the model -event if it's stored internally as uid. :)
http://backbonejs.org/#Model-idAttribute
Personally I don't like all that default values. Everything will be undefined if you don't set default values, which you can simply guard against with an if (undefined is a falsey value).
if(!model.get("messages")){
//no messages

d7726 | train | You will need to slightly modify the K2 view (we did this to one of our clients). You will need to create a query that resembles the following in the view:
SELECT count(*) FROM #__k2_items WHERE authorid='id';
Now you should pass the result of that query to the template (using the assignRef function on the $this object. That's it!

d7727 | train | The i variable is already defined as part of the for loop. Just remove the following line:
int i = 0;
A: int i = 0;
for(int i = 0; i < upper_limit + 1 ; i++ )
{
remove the int inside the for loop or the remove the line above the for loop. now you define int i twice
A: you define the variable i twice in your code. It should only be defined on time. I have highlighted the two times below.
Scanner input_scanner = new Scanner( System.in );
System.out.print( "Powers of 2 up to? " );
int upper_limit = input_scanner.nextInt();
int i = 0; //First time i is defined
for(int i = 0; i < upper_limit + 1 ; i++ ) //second time i is defined
{
System.out.println( i + " - " + Math.pow( 2, i));
}
To fix this either remove one of the int i = 0 lines. Both options shown below:
int upper_limit = input_scanner.nextInt();
//First definition removed
for(int i = 0; i < upper_limit + 1 ; i++ ) //second time i is defined
{
System.out.println( i + " - " + Math.pow( 2, i));
}
second solution
int upper_limit = input_scanner.nextInt();
int i = 0; //First time i is defined
for(; i < upper_limit + 1 ; i++ ) //second definition removed
{
System.out.println( i + " - " + Math.pow( 2, i));

d7728 | train | this code should demonstrate the basics of a post test. Assumes you have a repository injected into the controller. I am using MVC 4 RC not Beta here if you are using Beta the Request.CreateResponse(... is a little different so give me a shout...
Given controller code a little like this:
public class FooController : ApiController
{
private IRepository<Foo> _fooRepository;
public FooController(IRepository<Foo> fooRepository)
{
_fooRepository = fooRepository;
}
public HttpResponseMessage Post(Foo value)
{
HttpResponseMessage response;
Foo returnValue = _fooRepository.Save(value);
response = Request.CreateResponse<Foo>(HttpStatusCode.Created, returnValue, this.Configuration);
response.Headers.Location = "http://server.com/foos/1";
return response;
}
}
The unit test would look a little like this (NUnit and RhinoMock)
Foo dto = new Foo() {
Id = -1,
Name = "Hiya"
};
IRepository<Foo> fooRepository = MockRepository.GenerateMock<IRepository<Foo>>();
fooRepository.Stub(x => x.Save(dto)).Return(new Foo() { Id = 1, Name = "Hiya" });
FooController controller = new FooController(fooRepository);
controller.Request = new HttpRequestMessage(HttpMethod.Post, "http://server.com/foos");
//The line below was needed in WebApi RC as null config caused an issue after upgrade from Beta
controller.Configuration = new System.Web.Http.HttpConfiguration(new System.Web.Http.HttpRouteCollection());
var result = controller.Post(dto);
Assert.AreEqual(HttpStatusCode.Created, result.StatusCode, "Expecting a 201 Message");
var resultFoo = result.Content.ReadAsAsync<Foo>().Result;
Assert.IsNotNull(resultFoo, "Response was empty!");
Assert.AreEqual(1, resultFoo.Id, "Foo id should be set");
A: Using AutoFixture, I usually do something like this:
[Theory, AutoCatalogData]
public void PostToCollectionReturnsCorrectResponse(
CategoriesController sut,
CategoryRendition categoryRendition)
{
HttpResponseMessage response = sut.Post(categoryRendition);
Assert.Equal(HttpStatusCode.Created, response.StatusCode);
}

A: I've created a general solution for calling some action and getting HttpResponseMessage as Dictionary which is very convenient for usage.
First some extension for the dictionary:
public static class DictionaryExtensions
{
public static void AddRange<T, S>(this Dictionary<T, S> source,
Dictionary<T, S> collection)
{
if (collection == null)
{
throw new NullReferenceException("Collection is null");
}
foreach (var item in collection)
{
source.Add(item.Key, item.Value);
}
}
}
Now request creating part:
public class RequestCreator
{
protected static void FirstPart(ApiController controller,
HttpMethod method,String actionUrl)
{
// Creating basic request message with message type and requesting
// url example : 'http://www.someHostName/UrlPath/'
controller.Request = new HttpRequestMessage(method, actionUrl);
// Adding configuration for request
controller.Request.Properties.
Add(HttpPropertyKeys.HttpConfigurationKey,new HttpConfiguration());
}
protected static Dictionary<String, Object> SecondPart
(HttpResponseMessage response)
{
// Adding basic response content to dictionary
var resultCollection = new Dictionary<String, Object>
{
{"StatusCode",response.StatusCode},
{"Headers",response.Headers},
{"Version",response.Version},
{"RequestMessage",response.RequestMessage},
{"ReasonPhrase",response.ReasonPhrase},
{"IsSuccessStatusCode",response.IsSuccessStatusCode}
};
var responseContent = response.Content;
// If response has content then parsing it and
// getting content properties
if (null != responseContent)
{
var resultMessageString = response.Content.
ReadAsStringAsync().Result;
resultCollection.AddRange((new JavaScriptSerializer()).
DeserializeObject(resultMessageString)
as Dictionary<String, Object>);
}
return resultCollection;
}
}
And finally response message to dictionary converter class:
public class HttpResponseModelGetter : RequestCreator
{
public Dictionary<String, Object>
GetActionResponse(ApiController controller,HttpMethod method,
String actionUrl,Func<HttpResponseMessage> callBack)
{
FirstPart(controller, method, actionUrl);
var response = callBack();
return SecondPart(response);
}
}
public class HttpResponseModelGetter<T> : RequestCreator
{
public Dictionary<String, Object>
GetActionResponse(ApiController controller,HttpMethod method,
String actionUrl,Func<T,HttpResponseMessage> callBack,T param)
{
FirstPart(controller, method, actionUrl);
var response = callBack(param);
return SecondPart(response);
}
}
public class HttpResponseModelGetter<T1,T2> : RequestCreator
{
public Dictionary<String, Object>
GetActionResponse(ApiController controller,HttpMethod method,
String actionUrl,Func<T1,T2,HttpResponseMessage> callBack,
T1 param1,T2 param2)
{
FirstPart(controller, method, actionUrl);
var response = callBack(param1,param2);
return SecondPart(response);
}
}
//and so on...
and usage :
var responseGetter = new HttpResponseModelGetter();
var result = responseGetter.GetActionResponse(controller,HttpMethod.Get,
"http://localhost/Project/api/MyControllerApi/SomeApiMethod",
controller.SomeApiMethod);
Boolean isComplete = Boolean.Parse(result["isComplete"].ToString()); | unknown | |

StringTokenizer st = new StringTokenizer(br.readLine());

long qry=Integer.parseInt(st.nextToken());
long arr[]=new long[(int) n];
st = new StringTokenizer(br.readLine());
// read every number, adding with previous all numbers and store in the array index
arr[0] = Integer.parseInt(st.nextToken());
for (int i = 1; i <n ; i++) {
arr[i]=arr[i-1]+Integer.parseInt(st.nextToken());
}
for (int j = 0; j <qry ; j++) {
long sum=0;
double ans=0;
st = new StringTokenizer(br.readLine());
int L=Integer.parseInt(st.nextToken());
int R=Integer.parseInt(st.nextToken());
// check if the value 1 then don't subtract left value (as in that case there won't be any left value
// otherwise subtract just left most value from the array
if (L == 1) {
sum=arr[R-1]/(R-L+1);
} else {
sum=(arr[R-1] - arr[L-2])/(R-L+1);
}
ans=Math.floor(sum);
System.out.println((int) ans);

d7731 | train | What is a hyperlink, really? Its a text "button" that, when clicked, brings you to a website or opens a link of some sort.
So in this case, use a button in a tab on the Excel ribbon that when clicked brings you to a website. Easy:

d7732 | train | It all depends on how secure you want it to be. The simplest solution is to include a parameter in your POST request that only your backend and front-end instances would recognize - any random sequence of characters will do the trick. The next level is to use a secret key to encrypt the contents of the request - there are many implementations depending on the language that you use.
This approach is more flexible too, if you decide, for example, to move your backend from App Engine to Compute Engine. | unknown | |
d7733 | train | You might not intend to implement funcationaly but there is no need for imperative code in your example at all and returns and vars cause some serious issues when it comes to reading the intend of the code.
I would rewrite the code to something like this
sealed trait IP extends Product with Serializable
object IP {
final case class V4(a: Int, b: Int, c: Int, d: Int) extends IP
final case class V6(a: Int, b: Int, c: Int, d: Int, e: Int, f: Int, g: Int, h: Int) extends IP
}
val ipV4 = """(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})""".r
val ipV6 = """([0-9a-fA-F]+):""".r
def validIPAddress(ip: String): Either[String, IP] = {
def parseV4(s: String) = {
val i = Integer.parseInt(s)
if (0 <= i && i <= 255) Right(i) else Left(s"$i is not a valid IPv4 number")
}
def parseV6(s: String) = Integer.parseInt(s, 16)
ip match {
case ipV4(a, b, c, d) =>
for {
a1 <- parseV4(a)
b1 <- parseV4(b)
c1 <- parseV4(c)
d1 <- parseV4(d)
} yield IP.V4(a1, b1, c1, d1)
case ipV6(a, b, c, d, e, f, g, h) =>
// technically speaking this isn't exhausting all possible IPv6 addresses...
// as this regexp would ignore e.g. ::1 or ::
Right(IP.V6(parseV6(a), parseV6(b), parseV6(c), parseV6(d), parseV6(e), parseV6(f), parseV6(g), parseV6(h)))
case _ =>
Left(s"$ip is neither V4 nor V6 format")
}
}
to make it easier to follow and debug errors, though as I checked this implementation is NOT really conforming to what IPv6 does, as some tuning around regexp usage would be necessary. As a matter of the fact, I would prefer to avoid rolling my own solution altogether if I couldn't afford some time for writing down like 15-20 test cases.
So, unless there is a reason to implement your own validator I would delegate that task to some library which already tested handling corner cases.
If you have to, however, do the following things:
*
*don't use return - in Scala it does something different than what you think it does
*don't use vars unless you're optimizing - the way you use them have nothing to do with optimization (isValid is never used, so why override it? and other vars are never modified)
*don't use string for everything because that is asking for trouble on its own (e.g. "neither" and "Neither" - should the caller use .equalsIgnoreCase on your code to check results?)
*start with tests written basing on specification. While I translated your code it fails valid IPv6 addresses. If I skipped the requirement that Iv6 is fixed size, it would be even shorter to:
sealed trait IP extends Product with Serializable
object IP {
final case class V4(a: Int, b: Int, c: Int, d: Int) extends IP
final case class V6(values: List[Int]) extends IP
}
val ipV4 = """(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})""".r
val ipV6 = """([0-9a-fA-F]*)((:[0-9a-fA-F]*){2,})""".r
def validIPAddress(ip: String): Either[String, IP] = {
def parseV4(s: String) = {
val i = Integer.parseInt(s)
if (0 <= i && i <= 255) Right(i) else Left(s"$i is not a valid IPv4 number")
}
def parseV6(s: String) = if (s.isEmpty) 0 else Integer.parseInt(s, 16)
ip match {
case ipV4(a, b, c, d) =>
for {
a1 <- parseV4(a)
b1 <- parseV4(b)
c1 <- parseV4(c)
d1 <- parseV4(d)
} yield IP.V4(a1, b1, c1, d1)
case ipV6(head, tail, _) =>
val segments = head +: tail.substring(1).split(':')
Right(IP.V6(segments.map(parseV6).toList))
case _ =>
Left(s"$ip is neither V4 nor V6 format")
}
}
which handled more correct cases but is still far from ready. So if you can - avoid doing it yourself and use a library. | unknown | |

Reproducible: Always
Steps to Reproduce:
1. Unpack example zip provided
2. Try to import it to Eclipse: File->Import->Maven->Existing Maven Projects
A: First you can try to install maven globaly. follow the steps.
*
*Download maven from maven download link
*Create or export M2_HOME="MAVEN ROOT LOCATION". Ex. : E:\SoftwareRepo\building tools\apache-maven-3.5.2
*Create or export MAVEN bin folder location to PATH variable.
For example: E:\SoftwareRepo\building tools\apache-maven-3.5.2\bin
*Open terminal or cmd and run mvn --version to confirm maven is installed or not.
Then go to eclipse. and setup project.follow this steps
*
*Import existing maven project or create a maven project
*Goto project explorer and Right click on your pom.xml
*then select Run As maven install.
*and then what you want.
Hope it will serve your purpose. You can download a sample spring boot project from sample spring boot project
Or you can run a maven project from terminal or cmd. Just goto project root folder and then run a maven task like maven clean install .
Happy Coding :)
A: First install Java and then create the maven project.
Install the stable Java version in the system.
If Java is not installed then these types of errors will be displayed.

d7735 | train | [AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Product product)
{
...
return View("List");
}
or
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Product product)
{
...
return RedirectToAction("List", "Product");
}
A: your controller should work like this:
public class ProductController : Controller
{
IList<Product> products;
public ProductController( )
{
products = new List<Product>();
products.Add(new Product() { Id = 1, Name = "A", Price = 22.3 });
products.Add(new Product() { Id = 2, Name = "B", Price = 11.4 });
products.Add(new Product() { Id = 3, Name = "C", Price = 26.5 });
products.Add(new Product() { Id = 4, Name = "D", Price = 45.0 });
products.Add(new Product() { Id = 5, Name = "E", Price = 87.79 });
}
public ActionResult List( )
{
return View(products);
}
public ActionResult Create()
{
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Product product)
{
products.Add(product);
return View("List", products);
}
}
Additionally, you need to call RenderPartial instead of RenderAction, because otherwise your POST method will be invoked (due to you did a post-command by submitting the form):
<p>
<% Html.RenderPartial("Create"); %>
</p>
This should work, you only need to persist your products list, as it will reset with every postback.
I hope this helped you :)
A: Are the names of your text fields the same as the properties in your Product object?
Does your product object declare it's properties like this;
public string Name {get;set;}
You must have getters and setters on your objects.
EDIT
Wait, are you wanting fields from your list View to be available in the post to your create action? If yes then you need to place the BeginForm at the View level and not the PartialView level.
Only fields contained within the begin form will be posted to your controller.
EDIT 2
Ah, I think I see it now.
In your controller I think you should do a product.IsValid to check first.
But in your html you should also do this;
<%= Html.TextBox("Id", Model.Id) %>
You need to fill in the value for the text box.
Hope this is what you were after. | unknown | |

Ex:
def add(num1, num2):
try:
return (float(num1) + float(num2))
except ValueError:
return None
A: Try needs to be inside a function definition and does not need an else. Basically, the except functions as the try's else.
def add(num1, num2):
try:
return(float(num1) + float(num2))
except ValueError:
return(None)
A: you should do:
def add(num1, num2):
try:
return float(num1)+float(num2)
except:
return None
The problem is that you are trying to create a function but returning values outside that function, and for the case of your else statement, the function is not even defined at that point and you are calling it. | unknown | |
d7738 | train | I wanted to add a little to the above. In addition to selecting a branch of a tree, you often want descendants of only a certain depth. To accomplish this, many tables using add an additional computed column for "depth" ( something like [Depth] AS (myHierarchy.GetLevel]() ). With this extra column you can run queries like the following to limit by depth.
SELECT @MaxDepth = 3,
SELECT @theParent = Hierarchy,
@theParentDepth = Depth
FROM myTreeTable T
WHERE T.RowID = @RowID
SELECT myHierarchy
FROM myTreeTable T
WHERE T.myHierarchy.IsDescendantOf(@theParent) = 1 AND
T.Depth < (@theParentDepth + @MaxDepth)
Note, you may want to index the computed column (probably combined with or including some other columns) if you are relying on it heavily. | unknown | |
d7739 | train | You can change the levels of the variable -

df
# attend sex
#1 yes male
#2 no female
#3 no female
#4 <NA> male
#5 yes female
#6 yes male
#7 <NA> female
This will also automatically drop the 'iap' as level.
levels(df$attend)
#[1] "no" "yes"
Here we can also use forcats::fct_recode to turn specific values to NA.
df$attend <- forcats::fct_recode(df$attend, NULL = 'iap')
A: Another base R solution would be using exclude:
df$attend <- factor(df$attend, exclude = "iap")
attend sex
1 yes male
2 no female
3 no female
4 <NA> male
5 yes female
6 yes male
7 <NA> female | unknown | |

d7742 | train | The signature indicates the names and types of the input arguments, and (with type annotations) the type of the returned result(s) of a function or method.
This is not particular to Python, though the concept is more central in some other languages (like C++, where the same method name can exist with multiple signatures, and the types of the input arguments determine which one will be called).
A: In general the signature of a function is defined by the number and type of input arguments the function takes and the type of the result the function returns.
As an example in C++ consider the following function:
int multiply(int x, int y){
return x*y;
}
The signature of that function, described in an abstract way would be the set {int, int, int}.
As Python is a weakly typed language in general the signature is only given by the amount of parameters. But in newer Python versions type hints were introduced which clarify the signature:
def multiply(x: int, y: int) -> int:
return x*y
A: A function signature is its declaration, parameters, and return type.
def func(params):
#some stuff
return modified_params
When you call it is an instance of that function.
var = func(parameters) | unknown | |
d7743 | train | You'll have to convert the sets to lists too if you want to apply ordering.
The sorted() function gives you a sorted list from any iterable, letting you skip a step:
for key in sorted(index):
print('{:<20}{}'.format(key, ', '.join(str(i) for i in sorted(index[key]))))
Short demo:
>>> sorted(index)
['connected', 'depth first search', 'neighbor', 'path', 'shortest path', 'spanning tree', 'vertex']
>>> sorted(index['connected'])
[28, 54]
>>> for key in sorted(index):
... print('{:<20}{}'.format(key, ', '.join(str(i) for i in sorted(index[key]))))
...
connected 28, 54
depth first search 55
neighbor 27, 64, 77
path 19, 72
shortest path 55
spanning tree 16, 99
vertex 54
A: You can use the collections module in the standard library which has an OrderedDict type which is just a dict that remembers order of insertion.
If you want a dictionary in alphabetical order, where your values are ordered lists:
sorted_index = collections.OrderedDict(sorted(zip(index, map(sorted, index.values()))))
Since that is a bit of an ugly line you can expand it out as.
sorted_items = sorted(index.items())
sorted_items = [(k, sorted(v)) for k, v in sorted_items]
sorted_index = collections.OrderedDict(sorted_items) | unknown | |

d7745 | train | The enctype of the form should be multipart/form-data
A: You have errors in your html. You're missing closing tags for a tr and td tag. Also, close off your file upload input tag />.
A: Some of your logic is off:
if (!isset($_FILES[$upload_name]))
will always pass. For every <input type="file"> in your form, there'll be a matching $_FILES entry, whether a file was actually uploaded or not. If no file was uploaded to being with, then you'll get error code 4.
else if (isset($_FILES[$upload_name]['error']) && $_FILES[$upload_name]['error'] != 0)
You don't have to check if the error parameter is set. as long as $upload_name has a valid file field name in it, the error section will be there. You can check for $_FILES[$upload_name], though. in case your variable's set wrong.
You've commented it out, but you're checking for valid upload types by checking the user-provided filename. Remember that the ['type'] and ['name'] parameters in $_FILES are user-supplied and can be subverted. Nothing says a malicious user can't rename bad_virus.exe to cute_puppies.jpg and get through your 'validation' check. Always determine MIME type on the server, by using something like Fileinfo. That inspects the file's actual contents, not just the filename.
So, your upload validation should look something like:
if (isset($_FILES[$upload_name]) && ($_FILES[$upload_name]['error'] === UPLOAD_ERR_OK)) {
$fi = finfo_open(FILE_INFO_MIME_TYPE);
$mime = finfo_file($fi, $_FILES[$upload_name]['tmp_name']);
if (!in_array($valid_mime_type, $mime)) {
HandleError("Invalid file type $mime");
}
etc...
} else {
HandleError($uploadErrors[$_FILES[$upload_name]['error']]);

d7748 | train | Because the Count method is an extension method on IEnumerable<T> (Once you call Where, you don't have a list anymore, but an IEnumerable<T>). Extension methods don't work with dynamic types (at least in C#4.0).
Dynamic lookup will not be able to find extension methods. Whether extension methods apply or not depends on the static context of the call (i.e. which using clauses occur), and this context information is not currently kept as part of the payload.
Will the dynamic keyword in C#4 support extension methods?
A: Extension methods are syntactic sugar that allow you to call a static method as if it was a real method. The compiler uses imported namespaces to resolve the correct extension method and that is information the runtime doesn't have. You can still use the extension methods, you just have to call them directly in their static method form like below.
var aList = new List<string>{"a", "b", "c"};
dynamic a = aList.Where(item => item.StartsWith("a"));
dynamic b = Enumerable.Count(a); | unknown | |

d7752 | train | In regards to the array being passed around I believe it is indeed a reference and there isn't any real downside to doing this from a performance perspective.
It would be better to make the length available on Child Context that way you don't have to manually pass the props through a bunch of components that don't necessarily care.
also it seems it would be more clear to pass only the length since the component doesn't care about the actual objects in the array.
So in the component that holds the array the 5th level child cares about:
var React = require('react');
var ChildWhoDoesntNeedProps = require('./firstChild');
var Parent = React.createClass({
childContextTypes: {
arrayLen: React.PropTypes.number
},
getChildContext: function () {
return {
arrayLen: this.state.theArray.length
};
},
render: function () {
return (
<div>
<h1>Hello World</h1>
<ChildWhoDoesntNeedProps />
</div>
);
}
});
module.exports = Parent;
And then in the 5th level child, who is itself a child of ChildWhoDoesntNeedProps
var React = require('react')
var ArrayLengthReader = React.createClass({
contextTypes: {
arrayLen: React.PropTypes.number.isRequired
},
render: function () {
return (
<div>
The array length is: {this.context.arrayLen}
</div>
);
}
});
module.exports = ArrayLengthReader;
A: I don't see any problems with passing a big array as a props, even the Facebook is doing that in one of their tutorial about Flux.
Since you're passing the data down to this many lever you should use react contex.
Context allows children component to request some data to arrive from
component that is located higher in the hierarchy.
You should read this article about The Context, this will help you with your problem. | unknown | |

d7754 | train | You need to use web socket for real time notification. You can try Ratchet or socket.io. | unknown | |
d7755 | train | This is not recommended. It is generally considered bad practice to chop off the bottoms of bars. However, if you look at ?barplot, it has a ylim argument which can be combined with xpd = FALSE (which turns on "clipping") to chop off the bottom of the bars.
barplot(mtcars$mpg, ylim = c(10, 30), xpd = FALSE)
Also note that you should be careful here. I followed your question and used 0 and 30 as the y-bounds, but the maximum mpg is 33.9, so I also clipped the top of the 4 bars that have values > 30.
The only way I know of to make a "split" in an axis is using plotrix. So, based on
Specifically, I want to do this in base R program using only the barplot function and not functions from plotrix (unlike the suggests already provided). Is this possible?
the answer is "no, this is not possible" in the sense that I think you mean. plotrix certainly does it, and it uses base R functions, so you could do it however they do it, but then you might as well use plotrix.
You can plot on top of your barplot, perhaps a horizontal dashed line (like below) could help indicate that you're breaking the commonly accepted rules of what barplots should be:
abline(h = 10.2, col = "white", lwd = 2, lty = 2)
The resulting image is below:
Edit: You could use segments to spoof an axis break, something like this:
barplot(mtcars$mpg, ylim = c(10, 30), xpd = FALSE)
xbase = -1.5
xoff = 0.5
ybase = c(10.3, 10.7)
yoff = 0
segments(x0 = xbase - xoff, x1 = xbase + xoff,
y0 = ybase-yoff, y1 = ybase + yoff, xpd = T, lwd = 2)
abline(h = mean(ybase), lwd = 2, lty = 2, col = "white")
As-is, this is pretty fragile, the xbase was adjusted by hand as it will depend on the range of your data. You could switch the barplot to xaxs = "i" and set xbase = 0 for more predictability, but why not just use plotrix which has already done all this work for you?!
ggplot In comments you said you don't like the look of ggplot. This is easily customized, e.g.:
library(ggplot2)
ggplot(x, aes(y = mpg, x = id)) +
geom_bar(stat = "identity", color = "black", fill = "gray80", width = 0.8) +

d7759 | train | Unfortunately enum by default doesn't create an enum namespace. So when declaring:
enum PlayerType { FORWARD, DEFENSEMAN, GOALIE };
you'll have to use it like this:
auto x = FORWARD;
Thankfully, though, C++11 introduced enum class or enum struct to solve this issue:
enum class PlayerType { FORWARD, DEFENSEMAN, GOALIE };
You'll then be able to access it like you did:
auto x = PlayerType::FORWARD;
A: enum doesn´t create a namespace.
Therefor PlayerType t = PlayerType::FORWARD; should be changed to:
PlayerType t = FORWARD;
Notice that c++11 introduce enum classes, which have a namespace. Beside this MSVC has an extension which treats (regular) enums like they have namespace. So your code should actually work with MSVC.
A: Your error seems to be in this line:
PlayerType t = PlayerType::FORWARD;
As far as I know, the scope resolution operator (::) is not valid on regular C++98 enums unless your compiler supports them through non-standard extensions (like Visual Studio). Therefore you can't use it to reference an specific value from the enumerator.
Also, C++98 enums have the problem of polluting the namespace in which they are defined which can lead to name clash. Luckily C++11 solved this introducing the enum class. For more information check Stroustrup's FAQ: http://www.stroustrup.com/C++11FAQ.html#enum
A: add a static function say getForward:
class Player {
public:
Player();
void setType(PlayerType);
static PlayerType getForward {
return FORWARD;
}
private:
PlayerType type;
};
Then use it in main:

d7762 | train | Since you're using fetch to make the request, the response is encapsulated in the Response object, and to access it you have to call the async method json(). Just like the following:
const Response = await fetch(apiUrl + '/recipes', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': `Token token=${user.token}`
},
body: JSON.stringify({
recipe: {
recipeId: uri
}
})
});
const json = await Response.json();
console.log(json);
You can play with another example in your chrome console.
(async () => {
const Response = await fetch('https://jsonplaceholder.typicode.com/todos/1');
const res = await Response.json();
console.log(res);
})();
UPDATE
Another way to do that is:
(async () => {
const response = await (
await fetch('https://jsonplaceholder.typicode.com/todos/1')
).json();
console.log(response);

d7766 | train | Just wanted to add some coment over the previous answers. The contract of equals mentions that it must be symmetric. This means that a.equals(b) iff b.equals(a).
That's the reason why instanceof is usually not used in equals (unless the class is final). Indeed, if some subclass of Book (ComicsBook for example) overrides equals to test that the other object is also an instance of ComicsBook, you'll be in a situation where a Book instance is equal to a ComicsBook instance, but a ComicsBook instance is not equal to a Book instance.
You should thus (except when the class is final or in some other rare cases) rather compare the classes of the two objects:
if (this.getClass() != o.getClass()) {
return false;
}
BTW, that's what Eclipse does when it generates hashCode and equals methods.
A: Don't do this:
if(o.getID() == ID)
ID is an Integer object, not a primitive. Comparing two different but equal Integer objects using == will return false.
Use this:
if(o.getID().equals(ID))
You'd also need to check for ID being null.
Other than that, your logic is fine - you're sticking with the contract that says two equal objects must have the same hashcode, and you've made the business logic decision as to what equality means -a decision that only you can make (there's no one correct answer).
A: If you use Hibernate then you have to consider some Hibernate related concerns.
Hibernate create Proxies for Lazy Loading.
*
*always use getter to access the properties of the other object (you already done that)
*even if it is correct to use if (!this.getClass().equals(o.getClass())) { return false;} in a normal Application it WILL fail for hibernate Proxy (and all other proxies). The reason is if one of the two is a proxy, there classes will never be equals. So the test if(!(o instanceof Book)){return false;} is what you need.
If you want to do it in the symmetric way than have a look at org.hibernate.proxy.HibernateProxyHelper.getClassWithoutInitializingProxy() with help of this class you can implement:
if (!HibernateProxyHelper.getClassWithoutInitializingProxy(this)
.equals(HibernateProxyHelper.getClassWithoutInitializingProxy(o))) {
return false;
}
*
*An other problem maybe is the ID -- when you assign the id not with the creation of an new object but later on while storing them, then you can run into trouble. Assume this scenario: You create a new Book with id 0, then put the Book in a HashSet (it will assigned to an bucket in the hashset depending on the hashcode), later on you store the Book in the Database and the id is set to lets say 1. But this changes the hashcode, and you will have problems to find the entity in the set again. -- If this is a problem or not for you, strongly depends on your application, architecture and how you use hibernate.
A: It is no good idea to compare the two Integers like
if(o.getID() == ID) ...
This tests for identity. What you want is a test for equality:
if(ID!=null && ID.equals(o.getID())) ...
A: Just a note: Your equals method
public boolean equals(Object o)
{
if(o == null)
{
return false;
}
if(!(o instanceof Book))
{
return false;
}
Book other = (Book)o;
if(other.getID() == ID)
{
return true;
}
return false;
}
can be (equivalently) shorter written like this:
public boolean equals(Object o) {
return (o instanceof Book) &&
((Book)o).getID == ID;
}
Other than this, if your IDs are all different for different books (and same for same books), this is a good implementation.
(But note JB Nizet's remark: To make sure this stays symmetric, make equals (or the whole class) final.)
A: that depends !
i think this kind of implementation is ok, if you can handle the condition below,
you new two books, these two books have the same title, they are same book in fact, but you
don't save them into database, so these two books don't have ids yet, the equals will fall when you compare them | unknown | |

d7768 | train | From the looks of it, an "UML-XMI" is still an XML document, but as mentioned in the comments, it is not well-formed. The issue is with this node element
<node xmi:type="uml:OpaqueAction" xmi:id="_ZfIhYC9-EeWyX7UKkcyxiw" name="Load and Enable Timer" visibility="package" outgoing="_lieXcC9-EeWyX7UKkcyxiw" incoming="_jzMLIC9-EeWyX7UKkcyxiw"/>

</inputValue>
</node>
If you scroll to the right, the node tag is self-closed (i.e, it ends with />), this means the closing </node> tag doesn't actually match anything.
But assuming it was well-formed, the first issue with your XSLT is with namespaces. In your XML the namespace is defined like this:
xmlns:uml="http://www.eclipse.org/uml2/4.0.0/UML"
But in your XSLT you have defined it like this
xmlns:UML="org.omg.xmi.namespace.UML"
The prefix don't have to match between XML and XSLT, but the namespace URI does. Additionally, if your XSLT when you use the namespace prefix, you are using it in lower-case
<xsl:template match="/uml:Model/packagedElement/edge/">
It is case-sensitive though, so uml won't correspond to the UML which you have defined. The prefix doesn't need to match the XML, but it does need to match the one defined in the XSLT.
Additionally, that template match is also not syntactically correct because it ends with an / symbol. That needs to be removed.
Although I am not quite clear what output you actually want, try this XSLT to get you on your way:
<xsl:stylesheet version="1.0" xmlns:UML="http://www.eclipse.org/uml2/4.0.0/UML" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns='uri:sadf' exclude-result-prefixes="UML">

<xsl:template match="edge">

*first error message (original posted question)
SSO_SERVER needs a slash at the end:
SSO_SERVER='http://127.0.0.1:8000/server/'
*subsequent error message (from comment below):
Root cause is the coexistance of server and client in one app.
when you request /client/ there will be a request to get a token:
(see https://github.com/divio/django-simple-sso/blob/master/simple_sso/sso_client/client.py)
class LoginView(View):
...
def get(self, request):
...
request_token = self.client.get_request_token(redirect_to)
...
which will built an url from
SSO_SERVER='http://127.0.0.1:8000/server/' + reverse('simple-sso-request-token')
because you have the server in your server urls, reverse('simple-sso-request-token') returns "/server/request-token/"
Together you get
http://127.0.0.1:8000/server/server/request-token/
I am not sure if the path name "simple-sso-request-token" is needed somewhere else - if not, you could just "overwrite" it by adding a line with a dummy view to the urls.py just to make the reverse result change:
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
re_path(r'^server/', include(test_server.get_urls())),
re_path(r'^client/', include(test_client.get_urls())),
path("request-token/", some_dummy_view , name='simple-sso-request-token'), # this is only to force reverse("simple-sso-request-token") to return "request-token/"
]
(reverse() returns the last path in the urlpatterns list)
This will lead to
http://127.0.0.1:8000/server/request-token/

d7771 | train | It basically looks like the three.js ColladaLoader simply does not support material animations (it only supports position and rotation animations). I determined this by looking at raw data structure returned by the collada loader. Note how Object 0, which corresponds to the position animation has sids (string ids) and keys etc. Object 1, which corresponds to the material animation, has no sids or keys. While the material animation data is in the raw collada file, the ColladaLoader parser is simply not reading it, thus no color animations.
Apparently, the Collada loader is "kind of deprecated" per mrdoob (as of 5/2016). There is a ColladaLoader2, which is supposed to be the next version of the ColladaLoader, but I tried that and it appears to not support any animations at all. I've been reading up on the collada loader and indeed it is an aging format and basically looks likes it's a dead end as far as future growth goes (?)
Unfortunately, I've tried the obj, json, and stl loaders and the collada loader is by far the best. I'm currently investigating the gltf format, which basically seems like the next generation of collada (e.g the new and improved version also from the Khronos group). I found this discussion very useful. Basically, a couple of years ago there was a three.js user who wrote his own ColladaLoader, but he has since abandoned Collada and now backs glTF.
Update: I tried the GLTFLoader and GLTF2Loader loaders, but unfortunately they are failing on a semi-complex scene (a scene with 20 objects and 310 faces). It looks like a promising format though. I just think that between a test exporter and test loaders, it's just not quite stable at the moment. I was almost able to get animation working with the format (not material animation though) when I tested with a simple cube.
Looks like I'll have to stay with Collada for now and just do material animations in javascript. | unknown | |

d7780 | train | The reason why the worst case run time is O(n) is that if you have a careful look at the code, you realize that you visit each array index at most once:
observe that index i only increases at size, and index j only decrease, therefore you'll go at most once over each index.
For example, if you have an array a[] of size 10, then the initial index i will be 0, and j will be 9. x will be (randlomly) somewhere in between, let's say x=4.
Then, the outer while loop enters, and the first inner while loop increases index i until a[i] >= a[x].
The second inner while loop does the same to index j, for the opposite direction.
But the sum of total iterations of both inner loops is at most 10. At which point the next outer while loop check will return false and no second iteration will occur.
A: Lets start with this:
our teacher taught us that we have to multiply the costs whenever we have nested statements which would result in a (n/2+1)*((n/2)+1)+((n/2)+1)) which is clearly n^2 and not O(n)
This is only true if the looping variables in inner and outer loops are independent of each other.
eg.
for i in range(1..10):
for j in range(1..10):
do something
This is because, for every value of i, inner loop iterates for all values of j. So, this is O(n^2). Now, lets look the other example:
for i in range(1..10):
for i in range(1..10):
do something
In this case, the outer loop runs only once as when inner loop exits, condition for outer loop also discontinues. So, this is, O(n).
Now, lets look at your while loops.
The outer condition is while i is less than j. Inside, we are always incrementing i and decreasing j. So, in this case, the total number of times while statements (all 3) are executed will be the upper bound on i + j, which is 2n. So, complexity is O(2n) or, O(n).
EDIT:
I am making this edit to explain what "complexity" means, practically.
It is a way of approximating/calculating, number of iterations that are made in total, all loops and instructions combined, as size of input increases. So, if you really want to know that, just assign a variable, say a and add 1 to a as the 1st line of every loop. Then print a for different input sizes and you will know what O() notation means, theoretically vs practically. | unknown | |

d7783 | train | I can see no issue with such configuration.
Please have a look at the documentation Networks and subnets:
Each VPC network consists of one or more useful IP range partitions called subnets. Each subnet is associated with a
region.
and
A network must have at least one subnet before you can use it. Auto
mode VPC networks create subnets in each region automatically. Custom
mode VPC networks start with no subnets, giving you full control over
subnet creation. You can create more than one subnet per region.
So, accordingly to the documentation, it's possible to have a network test-network with two subnets subnet-a and subnet-b both in same region us-central1, for example:
$ gcloud compute networks create test-network --subnet-mode=custom --mtu=1460 --bgp-routing-mode=regional
$ gcloud compute networks subnets create subnet-a --range=10.0.1.0/24 --network=test-network --region=us-central1
$ gcloud compute networks subnets create subnet-b --range=10.0.2.0/24 --network=test-network --region=us-central1
$ gcloud compute networks list
NAME SUBNET_MODE BGP_ROUTING_MODE IPV4_RANGE GATEWAY_IPV4
test-network CUSTOM REGIONAL
$ gcloud compute networks subnets list
NAME REGION NETWORK RANGE
subnet-a us-central1 test-network 10.0.1.0/24
subnet-b us-central1 test-network 10.0.2.0/24
In addition have a look at the documentation section Communication within the network:
Except for the default network, you must explicitly create higher
priority ingress firewall rules to allow instances to communicate with
one another. The default network includes several firewall rules in
addition to the implied ones, including the default-allow-internal
rule, which permits instance-to-instance communication within the
network. The default network also comes with ingress rules allowing
protocols such as RDP and SSH.

d7784 | train | A,A2,C:C,">"&C2)
B is the Type column, A is the Reference column, and C is the Doc Condition column. So the count is only greater than zero if the Type is 'BD', the Reference Matches the current row's Reference, and the Doc Condition is greater than the current row's Doc Condition. I hope that makes sense?
I've tried coming to a solution using GroupBy but I'm not getting any closer to my desired solution and I think I'm overcomplicating this.
A: You should include your input data as text. Screenshots are really hard to work with.
You can use numpy broadcasting. However, this will have an n^2 computational complexity since you are comparing every row against every other row:
reference, type_, doc_condition = df.to_numpy().T
match = (
(type_[:, None] == "BD")
& (reference[:, None] == reference)
& (doc_condition[:, None] < doc_condition)
)
df["COUNTIFS"] = match.sum(axis=1)
Within the snippet above, you can read reference[:, None] as "the Reference value of the current row; reference as "the Reference values of all rows". This is what enables the comparison between the current row and all other rows (including itself) by numpy. | unknown | |

d7789 | train | I just learned from that the simultaneous allocation of multiple slaves can be done nicely in a pipeline job, by nesting node clauses:
node('label1') {
node('label2') {
// your code here
[...]
}
}
See this question where Mateusz suggested that solution for a similar problem.
A: Let me see if I understood the problem.
*
*You want to have dynamically choose a slave and start the App Server on it.
*When the App server is running on a Slave you do not want it to run any other job.
*But when the App server is not running, you want to use that Slave as any other Slave for other jobs.
One way out will be to label the Slaves. And use "Restrict where this project can be run" to make the App Server and the Test Suite run on the machines with Slave label.
Then in the slave nodes, put " # of executors" to 1. This will make sure that at anytime only one Job will run.
Next step will be to create a job to start the App Server and then kick off the Test job once the App Server start job is successful..
If your test job needs to know the server details of the machine where your App server is running then it becomes interesting. | unknown | |
d7790 | train | Your problem
The .order-* classes are limited at 5. It's in the documentation:
Includes support for 1 through 5 across
all six grid tiers. If you need more .order-* classes, you can modify
the default number via Sass variable.
And .order-6 is equal to order: last.
Easy solution
Add your own CSS classes.
@media (min-width: 768px) {
.order-md-6 {
order: 6;
}
.order-md-7 {
order: 7;
}
.order-md-8 {
order: 8;
}
.order-md-9 {
order: 9;
}
.order-md-10 {
order: 10;
}
}

Alternative solution
Overwrite the Sass. It can be found in the _utilities.scss. Here it is in Github. If you don't know how to do this, there are many tutorials to get you started, even here on SO. | unknown | |
d7791 | train | Issue : When you are trying to get the Status of the Row/Record by using Parent method of the jQuery, then it is not actually getting the correct element where you can find the status.
Solution : Change the following line of code
var status = $(e).parent().parent().find('.label-status').text();
to
var status = $(e).closest('.AddreqTableCols').find('.label-status').text();
A: i guess this is what you are trying to do, if its not clear enough what is happening, feel free to ask.
$("#selectall").click(function (e) {
var $this = $(this);
$("#tablecontent [type='checkbox']").prop("checked", $this.is(":checked"));
});
$("#deletebtn").click(function (e) {
if (!confirm("Are you sure you want to delete?")) return;
var $checked = $("#tablecontent [type='checkbox']:checked");
var ids = $.map($checked, function (chk) {
return $(chk).attr("id");
});
console.log(ids);
alert(ids.join(","));
});

COMMENT
If i was assigned to write the same thing, i would set the status as a data-status on the checkbox itself to make things easier.
A: The problem is that status is always empty. When you select a filterstatus it comes in the new if check and status == $('#filterstatus').val() will always be false since status is empty.
Change your code to:
var status = $(e).parent().parent().parent().find('.label-status').text();
You forgot an extra .parent().
Note: You can always use console.log() to test if your variables are filled in correctly. | unknown | |
d7792 | train | You can define to_csv function on user model like this.
def self.to_csv(users, options = {})
header_columns = [
"Email",
"First Name",
"Last Name"
]
CSV.generate(options) do |csv|
csv << header_columns
users.each do |user|
row = [
user.email,
user.first_name,
user.last_name
]
csv << row
end
end
end
And call it like this.
User.to_csv(@company.users)
A: require "csv" dont forget to include the module
@company.users.to_a.to_csv | unknown | |

d7796 | train | Why not place these scripts in App_data? It will be deployed along with the rest of the website, and cannot be accessed via client web browsers. That's what it is there for, to store data associated with your website that you don't want to have in the root for security purposes.
A: You can include an extra folder for deployment with all its contents editing the publish profile: http://www.asp.net/mvc/tutorials/deployment/visual-studio-web-deployment/deploying-extra-files | unknown | |
d7797 | train | David is going the right direction, such a protocol doesn't exist (simd is from C and C doesn't have protocols, no surprise), but you can just declare one yourself. To make it so you can use +-*/, you have to add them to the protocol:
import simd
protocol ArithmeticType {
func +(lhs: Self, rhs: Self) -> Self
func -(lhs: Self, rhs: Self) -> Self
func *(lhs: Self, rhs: Self) -> Self
func /(lhs: Self, rhs: Self) -> Self
}
extension float4 : ArithmeticType {}
extension float3 : ArithmeticType {}
extension float2 : ArithmeticType {}
func sum<T: ArithmeticType>(a: T, b: T) -> T {
return a + b
}
You can also extend Double, Float, Int, etc. if you need to
A: If there isn't (and there doesn't appear to be), it's easy enough to add your own:
protocol SimdFloat {}
extension float2 : SimdFloat {}
extension float3 : SimdFloat {}
extension float4 : SimdFloat {}
This doesn't really directly solve your problem, however as it doesn't declare that two SimdFloat's implement +. | unknown | |
d7798 | train | Dictionary lookups return optionals because the key might not exist. You need to unwrap each of the lookups since they are type SKTexture!:

runRight = SKAction.animateWithTextures([states["right1"]!, states["right2"]!, states["right1"]!, states["right3"]!], timePerFrame: 0.1) | unknown | |

d7800 | train | The mapping of inner objects is made with association tag. You need something like this:
<resultMap id="resmap" type="A">
<result property="a" column="a"/>
<association property="b" javaType="B">
<result property="b" column="b"/>
<result property="c" column="c"/>
</association>
