d8005 | train | The complexity of LCA is O(h) where h is the height of the tree. The upper bound of the tree height is O(n), where n denotes the number of vertices/nodes in the tree.
If your tree is balanced, (see AVL, red black tree) the height is order of log(n), consequently the total complexity of the algorithm is O(log(n)).
A: The worst case for this algorithm would be if the nodes are sibling leave nodes.
Node *LCA(Node *root, Node *p, Node *q)
{
for root call countMatchesPQ;
for(root->left_or_right_child) call countMatchesPQ; /* Recursive call */
for(root->left_or_right_child->left_or_right_child) call countMatchesPQ;
...
for(parent of leave nodes of p and q) call countMatchesPQ;
}
countMatchesPQ is called for height of tree times - 1. Lets call height of tree as h.
Now check the complexity of helper function
int countMatchesPQ(Node *root, Node *p, Node *q) {
Search p and q in left sub tree recursively
Search p and q in right sub tree recursively
}
So this is an extensive search and the final complexity is N where N is the number of nodes in the tree.
Adding both observations, total complexity of the algorithm is
O(h * N)
If tree is balanced, h = log N (RB tree, treap etc)
If tree is unbalanced, in worse case h may be up to N
So complexity in terms of N can be given as
For balanced binary tree: O(N logN)
To be more precise, it is actual h(N + N/2 + N/4...)
for balanced tree and hence should come 2hN
For unbalanced binary tree: O(N2)
To be more precise, it is actual h(N + N-1 + N-2...)
for balanced tree and hence should come h x N x (N+1) / 2
So the worse case complexity is N2
Your algorithm doesn't use any memory. By using some memory to save path, you can improve your algorithm drastically. | unknown | |

d8010 | train | According to the documentation for isEditing
Use the setEditing(_:animated:) method as an action method to animate the transition of this state if the view is already displayed.
And from setEditing(_:animated:)
Subclasses that use an edit-done button must override this method to change their view to an editable state if isEditing is true and a non-editable state if it is false. This method should invoke super’s implementation before updating its view.
TL;DR
You'll want to override setEditing(_:animated:) instead.

public function logout() {
Auth::user()->tokens->each(function($token, $key) {

This code will remove each token the user generated.
A: I think something like this can revoke the token:
$this->user->token()->revoke()
Based on this link.
A: Laravel Sanctum documentation stated 3 different ways to revoke tokens. you can find it here.
but for most cases we just revoke all user's tokens via:
// Revoke all tokens...
auth()->user()->tokens()->delete();
note: for some reason intelephense gives an error saying tokens() method not defined but the code works fine. Hirotaka Miyata found a workaround here.
so the over all logout method can be something like this:
public function logout()
{
//the comment below just to ignore intelephense(1013) annoying error.
/** @var \App\Models\User $user **/
$user = Auth::user();
$user->tokens()->delete();
return [
'message' => 'logged out'

A: the best working solution is this
public function logout(LogoutRequest $request): \Illuminate\Http\JsonResponse

d8015 | train | I agree with you. The open-source OAuth support classes available for .NET apps are hard to understand, overly complicated (how many methods are exposed by DotNetOpenAuth?), poorly designed (look at the methods with 10 string parameters in the OAuthBase.cs module from that google link you provided - there's no state management at all), or otherwise unsatisfactory.
It doesn't need to be this complicated.
I'm not an expert on OAuth, but I have produced an OAuth client-side manager class, that I use successfully with Twitter and TwitPic. It's relatively simple to use. It's open source and available here: Oauth.cs
For review, in OAuth 1.0a...kinda funny, there's a special name and it looks like a "standard" but as far as I know the only service that implements "OAuth 1.0a" is Twitter. I guess that's standard enough. ok, anyway in OAuth 1.0a, the way it works for desktop apps is this:
*
*You, the developer of the app, register the app and get a "consumer key" and "consumer secret". On Arstechnica, there's a well written analysis of why this model isn't the best, but as they say, it is what it is.
*Your app runs. The first time it runs, it needs to get the user to explicitly grant approval for the app to make oauth-authenticated REST requests to Twitter and its sister services (like TwitPic). To do this you must go through an approval process, involving explicit approval by the user. This happens only the first time the app runs. Like this:
*
*request a "request token". Aka temporary token.
*pop a web page, passing that request token as a query param. This web page presents UI to the user, asking "do you want to grant access to this app?"
*the user logs in to the twitter web page, and grants or denies access.
*the response html page appears. If the user has granted access, there's a PIN displayed in a 48-pt font
*the user now needs to cut/paste that pin into a windows form box, and click "Next" or something similar.
*the desktop app then does an oauth-authenticated request for an "Access token". Another REST request.
*the desktop app receives the "access token" and "access secret".
After the approval dance, the desktop app can just use the user-specific "access token" and "access secret" (along with the app-specific "consumer key" and "consumer secret") to do authenticated requests on behalf of the user to Twitter. These don't expire, although if the user de-authorizes the app, or if Twitter for some reason de-authorizes your app, or if you lose your access token and/or secret, you'd need to do the approval dance again.
If you're not clever, the UI flow can sort of mirror the multi-step OAuth message flow. There is a better way.
Use a WebBrowser control, and open the authorize web page within the desktop app. When the user clicks "Allow", grab the response text from that WebBrowser control, extract the PIN automatically, then get the access tokens. You send 5 or 6 HTTP requests but the user needs to see only a single Allow/Deny dialog. Simple.
Like this:
If you've got the UI sorted, the only challenge that remains is to produce oauth-signed requests. This trips up lots of people because the oauth signing requirements are sort of particular. That's what the simplified OAuth Manager class does.
Example code to request a token:
var oauth = new OAuth.Manager();
// the URL to obtain a temporary "request token"
var rtUrl = "https://api.twitter.com/oauth/request_token";
oauth["consumer_key"] = MY_APP_SPECIFIC_KEY;
oauth["consumer_secret"] = MY_APP_SPECIFIC_SECRET;
oauth.AcquireRequestToken(rtUrl, "POST");
THAT'S IT. Simple. As you can see from the code, the way to get to oauth parameters is via a string-based indexer, something like a dictionary. The AcquireRequestToken method sends an oauth-signed request to the URL of the service that grants request tokens, aka temporary tokens. For Twitter, this URL is "https://api.twitter.com/oauth/request_token". The oauth spec says you need to pack up the set of oauth parameters (token, token_secret, nonce, timestamp, consumer_key, version, and callback), in a certain way (url-encoded and joined by ampersands), and in a lexicographically-sorted order, generate a signature on that result, then pack up those same parameters along with the signature, stored in the new oauth_signature parameter, in a different way (joined by commas). The OAuth manager class does this for you automatically. It generates nonces and timestamps and versions and signatures automatically - your app doesn't need to care or be aware of that stuff. Just set the oauth parameter values and make a simple method call. the manager class sends out the request and parses the response for you.
Ok, then what? Once you get the request token, you pop the web browser UI in which the user will explicitly grant approval. If you do it right, you'll pop this in an embedded browser. For Twitter, the URL for this is "https://api.twitter.com/oauth/authorize?oauth_token=" with the oauth_token appended. Do this in code like so:
var url = SERVICE_SPECIFIC_AUTHORIZE_URL_STUB + oauth["token"];
webBrowser1.Url = new Uri(url);
(If you were doing this in an external browser you'd use System.Diagnostics.Process.Start(url).)
Setting the Url property causes the WebBrowser control to navigate to that page automatically.
When the user clicks the "Allow" button a new page will be loaded. It's an HTML form and it works the same as in a full browser. In your code, register a handler for the DocumentedCompleted event of the WebBrowser control, and in that handler, grab the pin:
var divMarker = "<div id=\"oauth_pin\">"; // the div for twitter's oauth pin
var index = webBrowser1.DocumentText.LastIndexOf(divMarker) + divMarker.Length;
var snip = web1.DocumentText.Substring(index);
var pin = RE.Regex.Replace(snip,"(?s)[^0-9]*([0-9]+).*", "$1").Trim();
That's a bit of HTML screen scraping.
After grabbing the pin, you don't need the web browser any more, so:
webBrowser1.Visible = false; // all done with the web UI
...and you might want to call Dispose() on it as well.
The next step is getting the access token, by sending another HTTP message along with that pin. This is another signed oauth call, constructed with the oauth ordering and formatting I described above. But once again this is really simple with the OAuth.Manager class:
oauth.AcquireAccessToken(URL_ACCESS_TOKEN,
"POST",
pin);
For Twitter, that URL is "https://api.twitter.com/oauth/access_token".
Now you have access tokens, and you can use them in signed HTTP requests. Like this:
var authzHeader = oauth.GenerateAuthzHeader(url, "POST");
...where url is the resource endpoint. To update the user's status, it would be "http://api.twitter.com/1/statuses/update.xml?status=Hello".
Then set that string into the HTTP Header named Authorization.
To interact with third-party services, like TwitPic, you need to construct a slightly different OAuth header, like this:
var authzHeader = oauth.GenerateCredsHeader(URL_VERIFY_CREDS,
"GET",
AUTHENTICATION_REALM);
For Twitter, the values for the verify creds url and realm are "https://api.twitter.com/1/account/verify_credentials.json", and "http://api.twitter.com/" respectively.
...and put that authorization string in an HTTP header called X-Verify-Credentials-Authorization. Then send that to your service, like TwitPic, along with whatever request you're sending.
That's it.
All together, the code to update twitter status might be something like this:
// the URL to obtain a temporary "request token"
var rtUrl = "https://api.twitter.com/oauth/request_token";
var oauth = new OAuth.Manager();
// The consumer_{key,secret} are obtained via registration
oauth["consumer_key"] = "~~~CONSUMER_KEY~~~~";
oauth["consumer_secret"] = "~~~CONSUMER_SECRET~~~";
oauth.AcquireRequestToken(rtUrl, "POST");
var authzUrl = "https://api.twitter.com/oauth/authorize?oauth_token=" + oauth["token"];
// here, should use a WebBrowser control.
System.Diagnostics.Process.Start(authzUrl); // example only!
// instruct the user to type in the PIN from that browser window
var pin = "...";
var atUrl = "https://api.twitter.com/oauth/access_token";
oauth.AcquireAccessToken(atUrl, "POST", pin);
// now, update twitter status using that access token
var appUrl = "http://api.twitter.com/1/statuses/update.xml?status=Hello";
var authzHeader = oauth.GenerateAuthzHeader(appUrl, "POST");
var request = (HttpWebRequest)WebRequest.Create(appUrl);
request.Method = "POST";
request.PreAuthenticate = true;
request.AllowWriteStreamBuffering = true;
request.Headers.Add("Authorization", authzHeader);
using (var response = (HttpWebResponse)request.GetResponse())
{
if (response.StatusCode != HttpStatusCode.OK)
MessageBox.Show("There's been a problem trying to tweet:" +
Environment.NewLine +
response.StatusDescription);
}
OAuth 1.0a is sort of complicated under the covers, but using it doesn't need to be.
The OAuth.Manager handles the generation of outgoing oauth requests, and the receiving and processing of oauth content in the responses. When the Request_token request gives you an oauth_token, your app doesn't need to store it. The Oauth.Manager is smart enough to do that automatically. Likewise when the access_token request gets back an access token and secret, you don't need to explicitly store those. The OAuth.Manager handles that state for you.
In subsequent runs, when you already have the access token and secret, you can instantiate the OAuth.Manager like this:
var oauth = new OAuth.Manager();
oauth["consumer_key"] = CONSUMER_KEY;
oauth["consumer_secret"] = CONSUMER_SECRET;
oauth["token"] = your_stored_access_token;
oauth["token_secret"] = your_stored_access_secret;
...and then generate authorization headers as above.
// now, update twitter status using that access token
var appUrl = "http://api.twitter.com/1/statuses/update.xml?status=Hello";
var authzHeader = oauth.GenerateAuthzHeader(appUrl, "POST");
var request = (HttpWebRequest)WebRequest.Create(appUrl);
request.Method = "POST";
request.PreAuthenticate = true;
request.AllowWriteStreamBuffering = true;
request.Headers.Add("Authorization", authzHeader);
using (var response = (HttpWebResponse)request.GetResponse())
{
if (response.StatusCode != HttpStatusCode.OK)
MessageBox.Show("There's been a problem trying to tweet:" +
Environment.NewLine +
response.StatusDescription);
}

d8019 | train | Look at this link, under the section "The ST monad":
http://book.realworldhaskell.org/read/advanced-library-design-building-a-bloom-filter.html
Back in the section called “Modifying array elements”, we mentioned
that modifying an immutable array is prohibitively expensive, as it
requires copying the entire array. Using a UArray does not change
this, so what can we do to reduce the cost to bearable levels?
In an imperative language, we would simply modify the elements of the
array in place; this will be our approach in Haskell, too.
Haskell provides a special monad, named ST, which lets us work
safely with mutable state. Compared to the State monad, it has some
powerful added capabilities.
We can thaw an immutable array to give a mutable array; modify the
mutable array in place; and freeze a new immutable array when we are
done.
...
The IO monad also provides these capabilities. The major difference between the two is that the ST monad is intentionally designed so that we can escape from it back into pure Haskell code.
So should be possible to modify in-place, and it won't defeat the purpose of using Haskell after all.
A: Yes, you would probably want to use the IO monad for mutable data. I don't believe the ST monad is a good fit for this problem space because the data updates are interleaved with actual IO actions (reading input streams). As you would need to perform the IO within ST by using unsafeIOToST, I find it preferable to just use IO directly. The other approach with ST is to continually thaw and freeze an array; this is messy because you need to guarantee that old copies of the data are never used.
Although evidence shows that a pure solution (in the form of Data.Sequence.Seq) is often faster than using mutable data, given your requirement that data be pushed out to OpenGL, you'll possible get better performance from working with the array directly. I would use the functions from Data.Vector.Storable.Mutable (from the vector package), as then you have access to the ForeignPtr for export.
You can look at arrows (Yampa) for one very common approach to event-driven code. Another area is Functional Reactivity (FRP). There are starting to be some reasonably mature libraries in this domain, such as Netwire or reactive-banana.

A: To see what the plugin is returning, do a console.log() call:
console.log($.cookie("language"));
This should tell you what is being returned from the plugin if you monitor your Inspector / Firebug console.
I think you can get away with just doing if($.cookie("language")) but you'll have to test that.
A: Line #90 in the source looks like that SHOULD be the result you want. Check for any errors and test what happens if the cookie is set.

d8024 | train | To answer your question:
This answer should help you. You should (!?) be able to use ./sql_exporter & to run the process in the background (when not using --stdin --tty). If that doesn't work, you can try nohup as described by the same answer.
To recommend a better approach:
Using kubectl exec is not a good way to program a Kubernetes cluster.
kubectl exec is best used for debugging rather than deploying solutions to a cluster.
I assume someone has created a Kubernetes Deployment (or similar) for Microsoft SQL Server. You now want to complement that Deployment with the exporter.
You have options:
*
*Augment the existing Deployment and add the sql_exporter as a sidecar (another container) in the Pod that includes the Microsoft SQL Server container. The exporter accesses the SQL Server via localhost. This is a common pattern when deploying functionality that complements an application (e.g. logging, monitoring)
*Create a new Deployment (or similar) for the sql_exporter and run it as a standalone Service. Configure it scrape one|more Microsoft SQL Server instances.
Both these approaches:
*
*take more work but they're "more Kubernetes" solutions and provide better repeatability|auditability etc.
*require that you create a container for sql_exporter (although I assume the exporter's authors already provide this). | unknown | |

d8026 | train | This answer has been outdated by substantial changes in OP question
I am quite sure there is no such feature in NHibernate, or any other ORM.
By the way, what should yield updating Id 3 to Cat after having updated it to Dog?
Id | Animal
1 |
2 |
3 | Cat
If that means that Id 1&2 now have the empty string value, that will be an unique constraint violation too.
If they have the null value, it depends then on the db engine being ANSI null compliant or not (null not considered equal to null). This is not the case of SQL Server, any version I know of, at least for the case of unique indexes. (I have not tested the unique constraint case.)
Anyway, this kind of logic, updating a row resulting in an additional update on some other rows, has to be handled explicitly.
You have many options for that:
*
*Before each assignment to the Animal property, query the db for finding if another one has that name and take appropriate action on that another one. Take care of flushing right after having handling this other one, for ensuring it get handled prior to the actual update of the first one.
*Or inject an event or an interceptor in NHibernate for catching any update on any entities, and add there your check for duplicates. Stack Overflow has examples of NHibernate events or interceptors, like this one.
But your case will probably bit a bit tough, since flushing some other changes while already flushing a session will probably cause troubles. You may have to directly tinker with the sql statement with IInterceptor.OnPrepareStatement by example, for injecting your other update first in it.
*Or handle that with some trigger in DB.
*Or detect a failed flush due to an unique constraint, analyze it and take appropriate action.
The third option is very likely easier and more robust than the others. | unknown | |

This is the second attempt. Earlier I understood you wanted to copy and paste the HTML as text but after your comments and edits to the question I now understand that you have some text that you format using HTML and you want to paste that text while retaining the formatting.

The code is very similar to before. The problem is that HTML = plain text so to copy HTML and retain the style or formatting also depends on the destination app into which you paste it. That destination app needs to handle the HTML correctly for what you want to achieve.
Anyhow, here are the changes from earlier.
On the copy side: the text is now copied as HTML and not as a string. There is very little difference there except that now, unlike before, the string is converted to data and the type is marked as kUTTypeHTML.
On the paste side: the real difference is here. If the pasteboard contains HTML then it is retrieved and formatted using an attributed string. It also works fine if you e.g. paste into Notes BTW.
This illustrates the problem you are dealing with here. I could just as well have used the code I used earlier and everything would work but in stead of formatted HTML I would get the unformatted / source HTML.
Here I assume that you are interested in fairly simple but formatted text. You did not mention text specifically and if you e.g. wanted to copy an HTML formatted table then my example is not adequate as I use a UITextView as destination.
For more complex HTML I'd use a WKWebView as destination as well and set its HTML string to the pasted in HTML, but again, this shows how the destination app also needs to cooperate in handling the HTML correctly.
Finally, looking at the updated answer and your code it is difficult to spot a difference, so I suspect your problem could be earlier with content itself in
RCT_EXPORT_METHOD(setString:(NSString *)content)
UPDATE
I also looked at the git repository you mention. There I found the following
RCT_EXPORT_METHOD(hasString:(RCTPromiseResolveBlock)resolve
reject:(__unused RCTPromiseRejectBlock)reject)
{
BOOL stringPresent = YES;
UIPasteboard *clipboard = [UIPasteboard generalPasteboard];
if (@available(iOS 10, *)) {
stringPresent = clipboard.hasStrings;
} else {
NSString* stringInPasteboard = clipboard.string;
stringPresent = [stringInPasteboard length] == 0;
}
resolve([NSNumber numberWithBool: stringPresent]);
}
It looks wrong, I think that one line should be
stringPresent = [stringInPasteboard length] != 0;
HTH
A: I found the answer here: http://www.andrewhoyer.com/converting-html-to-nsattributedstring-copy-to-clipboard/
The string needed to be converted to RTF before it was put in the clipboard.
RCT_EXPORT_METHOD(setString:(NSString *)content)
{
// Source: http://www.andrewhoyer.com/converting-html-to-nsattributedstring-copy-to-clipboard/
UIPasteboard *clipboard = [UIPasteboard generalPasteboard];

// Create the attributed string using options to indicate HTML text and UTF8 string as the source.

d8031 | train | Aside from a typo (you duplicated select, and you didn't terminate the RETURN statement with a semicolon), I think you were quite close - just needed to disambiguate the table columns within the query by qualifying them with the table name. Try this (reformatted hopefully to improve readability):

Caveat: I only tested this in PG 9.4, so haven't tested it in your version yet (which is no longer supported, I might add). In case there are issues regarding PLPGSQL implementation between your version and 9.4, you can try this form as an alternative:

d8032 | train | 1.) At least you need to fix:
public void changeNumOne(int NewNumOne){
firstNum = NewNumOne;
}
// Error: Same name as above
public void changeNumOne(int NewNumTwo){
// Error: Capital SecondName
SecondNum = NewNumTwo;
}
To:
public void changeNumOne(int firstNum){
this.firstNum = firstNum;
}
public void changeNumTwo(int secondNum){
this.secondNum = secondNum;
}
2.) And here you would like to print result, but your class does not have such a variable (also check, if your function calculateNums makes sense):
public void showResults(){
System.out.println(firstNum + " " + operation + " " + secondNum + " = " + result);
}
3.) This should also fail:
public Calculator(int firstNum, int secondNum, int NumOperation){
NumOne = firstNum;
NumTwo = secondNum;
NumOperation = operation;
}
Should be:
public Calculator(int firstNum, int secondNum, string operation){
this.firstNum = firstNum;
this.secondNum = secondNum;
this.operation = operation;
}
4.) Here you do not assign the values:
public Calculator(){
int firstNum = 0;
int secondNum = 0;
operation = "Addition";
}
Should be:
public Calculator(){
this.firstNum = 0;
this.secondNum = 0;
this.operation = "Addition";
}
Overall:
There might be other errors.
You need to check all your variables names. They are quite inconsistent. Though, read your error messages carefully and try to understand them for the future.
A: There are many errors. I solved with this code, acting with Calculator class. I commented on the code where there were errors.
class Calculator {
// instance variables - first number, second number, operation
private int firstNum;
private int secondNum;
private int result; //I declare the result variable so I can print it
private String operation;
// static field to keep track of number of Calculator objects
public static int Calculatorobjects = 0;
// default constructor
public Calculator(){
this.firstNum = 0; //useless because uninitialized int are already 0
this.secondNum = 0; //same
this.operation = "Addition";
}
// initializing constructor
public Calculator(int firstNum, int secondNum, String NumOperation){ //NumOperation is a String, not an int
this.firstNum = firstNum; //I'm setting the global variables as the local variables that you pass to the constructor
this.secondNum = secondNum;
this.operation = NumOperation;
}
// getters for all 3 instance variables
public int one(){
return firstNum;
}
public int two(){
return secondNum;
}
public String three(){
return operation;
}
// setters to be able to change any of the 3 instance variables after creating them
public void changeNumOne(int NewNumOne){
firstNum = NewNumOne;
}
public void changeNumTwo(int NewNumTwo){. //changed method name
secondNum = NewNumTwo;
}
public void changeNumOne(String NewNumOperation){
operation = NewNumOperation;
}
// instance method to perform operation
public void calculateNums(){
if(operation.equals("Addition")){ //equals is used to compare strings
result = firstNum + secondNum;
}

d8033 | train | JavaScript events bubble up the DOM by default, so events triggered on a children will be triggered on the parent.
To prevent this, you need to stop the propagation of the event.
This is done by:
event.stopPropagation();
Note that event is usually passed as a parameter to your callback functions. (Meaning, don't use onclick="" attributes so you get function callback)

d8034 | train | One way to solve this problem is to project each Animal to a Task that contains more information than either a naked name or a naked error. For example you could project it to a Task<ValueTuple<Animal, string, Exception>> that contains three pieces of information: the animal, the animal's scientific name from the zooApi, and the error that may have happened while invoking the zooApi.GetScientificNameAsync method.
The easiest way to do this projection is the LINQ Select operator:
List<Task<(Animal, string, Exception)>> tasks = animals.Select(async animal =>
{
try
{
return (animal, await this.zooApi.GetScientificNameAsync(animal),
(Exception)null);
}
catch (Exception ex)
{
return (animal, null, ex);
}
}).ToList();
(Animal, string, Exception)[] results = await Task.WhenAll(tasks);
foreach (var (animal, scientificName, error) in results)
{
if (error != null)
this.logger.LogError(error,
$"The {animal.Name} from {animal.Country} was not found");
}
A: You have almost nailed it. :)
Rather than having a List<Task<string>> you need a Dictionary<Task<string>, string> structure:
static async Task Main()
{
var taskInputMapping = new Dictionary<Task<string>, string>();
var inputs = new[] { "input", "fault", "error", "test"};
foreach (var input in inputs)
{
taskInputMapping.Add(DelayEcho(input), input);
}
try
{
await Task.WhenAll(taskInputMapping.Keys);
}
catch
{
foreach (var pair in taskInputMapping.Where(t => t.Key.IsFaulted))
{
Console.WriteLine($"{pair.Value}: {pair.Key.Exception?.GetType().Name}");
}
}
}
static readonly ImmutableArray<string> wrongInputs =
ImmutableArray.Create("error", "fault");
static async Task<string> DelayEcho(string input)
{
if (wrongInputs.Contains(input)) throw new ArgumentException();
await Task.Delay(10);
return input;
}
*
*taskInputMapping.Add(DelayEcho(input), input): Stores the input next to the Task itself
*taskInputMapping.Where(t => t.Key.IsFaulted): Iterates through the faulted tasks
*$"{pair.Value}: {pair.Key.Exception?.GetType().Name}": Retrieves the input + the related error
A: I combined the answers and came up with this:
var tasks = animals.Select(async animal =>

try
{
return await this.zooApi.GetNameAsync(animal);
}
catch (Exception ex)
{
this.logger.LogError(error,
$"The {animal.Name} from {animal.Country} was not found");

d8035 | train | You seem to be asking two different questions. In the first paragraph you're asking about bundles that are bound to you, which I interpret to mean bundles that import your exported packaged. In the second you're asking about consumers of your services; these are orthogonal issues.
For the first question, you can use the BundleWiring API:
BundleWiring myWiring = myBundle.adapt(BundleWiring.class);
List<BundleWire> exports = myWiring.getProvidedWires(PackageNamespace.PACKAGE_NAMESPACE);
for (BundleWire export : exports) {
Bundle importer = export.getRequirerWiring().getBundle()
}
For services, you can use the ServiceFactory pattern. By registering your service as an instance of ServiceFactory rather than directly as an instance of the service interface you can keep track of the bundles that consume your service. Here is a skeleton of a service implementation using this pattern:
public class MyServiceFactory implements ServiceFactory<MyServiceImpl> {
public MyServiceImpl getService(Bundle bundle, ServiceRegistration reg) {
// create an instance of the service, customised for the consumer bundle
return new MyServiceImpl(bundle);
}
public void ungetService(Bundle bundle, ServiceRegistration reg, MyServiceImpl svc) {
// release the resources used by the service impl
svc.releaseResources();
}
}
UPDATE: Since you are implementing your service with DS, things are a bit easier. DS manages the creation of the instance for you... the only slightly tricky thing is working out which bundle is your consumer:
@Component(servicefactory = true)
public class MyComponent {
@Activate
public void activate(ComponentContext context) {
Bundle consumer = context.getUsingBundle();
// ...
}
}
In many cases you don't even need to get the ComponentContext and the consuming bundle. If you are assigning resources for each consumer bundle, then you can just save those into instance fields of the component, and remember to clean them up in your deactivate method. DS will create an instance of the component class for each consumer bundle. | unknown | |

d8039 | train | The only way that I know, is to use a computed subform.
if the doc has the flag, show subform with field that have the property "Look up names as each character is entered".
if the doc has not the flag, show subform with field that not have the property "Look up names as each character is entered".
A: Using a subform as stated by adminfd is one possibility. But it has some disadvantages:
*
*you don't see the content of a computed subform in designer and cannot double click (inconvenient for developers).
*using a lot of subforms can make loading the form very slow
I usually do things like that with additional fields. I make the field itself hidden and computed with the formula:
@If( YourCondition; FieldNameWithLookup; FieldNameWithoutLookup );
Then I create two fields above the hidden field, name them FieldNameWithLookup and FieldNameWithoutLookup and hide them using the same condition as in the Value- Formula of the field.
Yes, it produces some overhead as there are two additional fields, that are not necessary, but I simply like this approach more.
If you have existing documents, then you need the formula FieldName in the two new fields as default values and probably some code, if the Condition value for displaying one or the other field changes during different states of the document... | unknown | |

d8041 | train | Yes, this code is almost correct, with a slight exception. Your call to getData should look like:
getData(temp_array, sizeof(T));
You should not be passing the address of array into your getValue function. Other than that, it is good, and it doesn't suffer from quite common strict aliasing violation.
You are also avoiding any issues of alignment, and the code is as optimal as can be give the API.
A: A problem I see is that because you are only templating the returned value, you will need to explicitly specify the type to use your template method, i.e.
auto val = getValue<uint32_t>();
isDataGood(val); // Should be!
Without using auto, this is prone to mismatch errors, not all of which will be reported:
uint32_t val = getValue<uint16_t>();
isDataGood(val); // perhaps not!
It depends how heavy-handed you want to be to protect against this, but one way is to make the returned value a parameter, which allows template type deduction:
uint32_t val;
getValue(val);
isDataGood(val); // Must be!
Another is to not use raw integers, but always a struct containing the value as a member of the right size. You can't trivially switch between structs like you can between integer sizes.
Another is to have getValue return a wrapper that for a given type knows how to cast to it, and for other types, fails to cast at compile time:
struct FailIntBase
{
operator uint8_t()const = delete;
operator uint16_t()const = delete;
operator uint32_t()const = delete;
operator uint64_t()const = delete;
// etc
};
template <class Castable> struct SafeInt: FailIntBase
{
Castable val;
SafeInt(Castable val): val(val) {}
operator Castable()const
{ return val; }
};
template <typename T>
SafeInt<T> getValue() { //...
// Testing:
auto X = getValue<uint16_t>();
uint16_t Y = getValue<uint16_t>();
uint32_t Z = getValue<uint16_t>(); //error: use of deleted function 'FailIntBase::operator uint32_t() const'
If you need to cover more types including signed types, you can get away with a much smaller implementation of FailIntBase if you can live with the less informative error message:
conversion from 'SafeInt<short unsigned int>' to 'uint32_t' {aka 'unsigned int'} is ambiguous

You can use the index argument provided by each() instead:
$(".fancybox").each(function(index) {
$(this).attr("title", mapDetails[index]);
});
That way, the index will keep incrementing for each element and will not reset between maps.
A: You should use the index of each()
$('.fancybox').each(function(index, el) {
$(this).attr('title', mapDetails[index]);
}) | unknown | |
d8043 | train | If you have the Apache service monitor in your system tray, you can just open that (right click, I think?) and click "restart Apache".
If it's not in your system tray, you can find it in the /bin folder of the Apache installation (called ApacheMonitor.exe). I'd recommend making a shortcut to it in the "Startup" folder.
A: Copy apache_start.bat and rename it to apache_restart.bat.
Change the line apache\bin\httpd.exe to apache\bin\httpd.exe -k restart
Voila, there you go with your restart script.
and you can also give it a shortcut.
A: For me, with the version 3.2.2 the first answer didn't work.
I've put together a script from the two apache_start.bat and apache_stop.bat files.
@echo off
cd /D %~dp0
echo Apache 2 is stopping...
apache\bin\pv -f -k httpd.exe -q
if not exist apache\logs\httpd.pid GOTO exit
del apache\logs\httpd.pid

echo.
echo Apache konnte nicht gestartet werden

// here shortcut evaluation below ios(13.0)
}
@end
is only invoked on iPhones or iPads with iOS lower Version 13.0
So to make it work in iOS(13.0,*) and above you need to implement it in SceneDelegate with a slightly different name, see below.. (matt was right!)

A: Sorry being too late. Further research about home quick actions showed me the following conclusions after discussing with major developers . The following points which needed to be followed while integrating HomeQuickActions are :
*
*Most Important point for every developer: Home quick actions(short cut items on clicking app icon) are definitely OS and hardware based (supported only from iOS 13). Apple documents. It means before iOS 13 no device will show app short cut items even if they have Haptic Touch / 3D Touch. iOS 13 and above is a mandatory requirement.(Checked in Simulator for all iPhone, need to test in real device with older phones)
Both 3D touch enable and non-3D touch enabled devices support this feature through force-touch or long-press depending on device capabilities if they are capable of running iOS 13 or above.
*So for App short cuts to work the iOS devices must be having iOS 13 for sure and the hardware compatibility is also required which means the devices must be having iOS 13 and above for App short cuts to work. For iPhone 5S, iPhone 6 owners: iOS 13 won't be compatible anymore.
*Since Apple has replaced 3D Touch hardware with Haptic Touch , the newer iPhones from iPhone XR will have only Haptic Touch . Old devices after SE(1 st generation, iPhone 6 series till iPhone X ) have 3D Touch hardware. Haptic Touch is a software OS dependent which uses finger pressed area and 3D Touch is a hardware dependent which uses a specific sensor between screen. | unknown | |
d8047 | train | Since we're working with a Voronoi tessellation, we can simplify the current algorithm. Given a grid point p, it belongs to the cell of some site q. Take the minimum over each neighboring site r of the distance from p to the plane that is the perpendicular bisector of qr. We don't need to worry whether the closest point s on the plane belongs to the face between q and r; if not, the segment ps intersects some other face of the cell, which is necessarily closer.
Actually it doesn't even matter if we loop r over some sites that are not neighbors. So if you don't have access to a point location subroutine, or it's slow, we can use a fast nearest neighbors algorithm. Given the grid point p, we know that q is the closest site. Find the second closest site r and compute the distance d(p, bisector(qr)) as above. Now we can prune the sites that are too far away from q (for every other site s, we have d(p, bisector(qs)) ≥ d(q, s)/2 − d(p, q), so we can prune s unless d(q, s) ≤ 2 (d(p, bisector(qr)) + d(p, q))) and keep going until we have either considered or pruned every other site. To do pruning in the best possible way requires access to the guts of the nearest neighbor algorithm; I know that it slots right into the best-first depth-first search of a kd-tree or a cover tree. | unknown | |
d8048 | train | In theory, you'll want to set the context of your ajax request to the element containing the text you want. Then on success, you would increase the number in that context.
$.ajax({
/* everything else as before */
context: $('selector for element containing number to increase'),
success: function(result) {
$(this).html(parseInt($(this).html(), 10) + 1);
}
});
This assumes that the content of the context element will always be a single integer
If you need to select a cell by it's column and row, you could do the following:
var column = 1;
var row = 1;
var $cell = $('table tr:eq(' + row + ') td:eq(' + column + ')');
$cell.html(parseInt($cell.html(), 10) + 1);
See fiddle: http://jsfiddle.net/xixionia/4HLp9/
Although, you would need to change "table" to a table's id, otherwise you'll end up selecting all of the cells from every table at that row in and column.
Note: Having seen your html, we would be able to provide a much more detailed description of how to select the desired cell.
A: How many rows do you have? It might make sense just to re-generate the table from the AJAX call and reload the html on it's way back. | unknown | |

d8052 | train | It looks like spring won't be helpful here, but you still can do that.
This @Valid annotation processing implementation is basically in integration with project Hibernate Validator (Don't get confused with the name, it has nothing to do with Hibernate ORM ;) )
So you could create the engine and validate "manually".
An example of using the validation engine:
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
validator = factory.getValidator();
User user = ...
Set<ConstraintViolation<User>> constraintViolations = validator.validate( user );
As you see, the Result of the validation in hibernate validator is not an exception (this is something that spring has added on top to better integrate with web mvc flow) but rather a set of "validation constraint violations". So basically is this set is not empty, there is at least one validation error so that you could filter it out.
I believe wrapping the this logic into filter is not that interesting once you're familiar with the foundations... | unknown | |
d8053 | train | I managed to do this by manually concatenating the state into a single tensor. I'm not sure if this is wise, since this is how tensorflow used to handle states, but is now deprecating that and switching to tuple states. Instead of setting state_is_tuple=False and risking my code being obsolete soon, I've added extra ops to manually stack and unstack the states to and from a single tensor. Saying that, it works fine both in python and C++.
The key code is:
# setting up
zero_state = cell.zero_state(batch_size, tf.float32)
state_in = tf.identity(zero_state, name='state_in')
# based on https://medium.com/@erikhallstrm/using-the-tensorflow-multilayered-lstm-api-f6e7da7bbe40#.zhg4zwteg
state_per_layer_list = tf.unstack(state_in, axis=0)
state_in_tuple = tuple(
# TODO make this not hard-coded to LSTM
[tf.contrib.rnn.LSTMStateTuple(state_per_layer_list[idx][0], state_per_layer_list[idx][1])
for idx in range(num_layers)]
)
outputs, state_out_tuple = legacy_seq2seq.rnn_decoder(inputs, state_in_tuple, cell, loop_function=loop if infer else None)
state_out = tf.identity(state_out_tuple, name='state_out')
# running (training or inference)
state = sess.run('state_in:0') # zero state
loop:
feed = {'data_in:0': x, 'state_in:0': state}
[y, state] = sess.run(['data_out:0', 'state_out:0'], feed)

Try this maybe. You re locking the lock and unlocking the lock in different threads. The thread that call theput method is the one using lock.lock() so it is the only one that can unlock it. The code inside the new Thread(....) belong to another thread so calling lock.unlock() there will not work. Also in the current code I don't see any use of the lock and condition, you can just remove all this (unless you plan on using it somewhere else we don't see), you can put and remove from a concurrent map with worrying about managing the access yourself.
A: In order to wait or notify (await and signal if using Condition) the thread, which performs an action, must own the lock it's trying to wait or notify on.
From your example: you put a lock in the main thread (lock.put()), then start a new thread. The new thread does not own the lock (it's still held by the main thread), but despite that you try to invoke signalAll() and get IllegalMonitorStateException.
In order to fix the problem you should:
1. Release the lock the main thread holds when it's ready (you never release it at the moment).
2. Lock in the new thread first and only then call signalAll()
3. Release the lock in the new thread when you're ready. Do it in the finally clause of the try-catch block to guarantee that the lock gets released in case of an exception.
Also a few moments:
- in order to be notified a thread must be waiting for notification.
- synchronization on the put() method is redundant, since you're already using a ReentrantLock inside.
A: We have a few things to look at here:
*
*lock
*removed which is a condition created using lock
Your main thread acquires a lock on lock in the put method.
However it never releases the lock; instead it creates a new Thread that calls removed.signalAll(). However this new thread does not hold a lock lock which would be required to do this.
I think what you need to do is to make sure that every thread that locks lock also unlocks it and that every thread calling signalAll also has a lock.
public synchronized void put(K k, V o) {
a.put(k, o);
new Thread(() -> {
try {
TimeUnit.SECONDS.sleep(delay);
lock.lock(); // get control over lock here
a.remove(k, o);
removed.signalAll();
lock.unlock();
} catch (InterruptedException e) {
e.printStackTrace();

*Delete the table for your genres if created manually (with SQL code)
DROP TABLE genres;
*generate a complete scaffolding for genres:
$ ruby script/generate genre name:string
$ rake db:migrate

d8063 | train | Short Answer :
Add a class to the images for rating, say a class "rating" and then replace $("img") with $("img.rating")
Long Answer :
Ok, the jquery selector you are using is this $("img") which says select all images from the page. Hence the problem.
Now what you should do,
As you want to have the jquery run only for the 5 Rating images, you can have all the images have a common class like as shown below..
<img class="Rating" src="../../Content/Images/EmptyStar.png" alt="Star Rating" align="middle" id="1" />
<img class="Rating" src="../../Content/Images/EmptyStar.png" alt="Star Rating" align="middle" id="2" />
<img class="Rating" src="../../Content/Images/EmptyStar.png" alt="Star Rating" align="middle" id="3" />
<img class="Rating" src="../../Content/Images/EmptyStar.png" alt="Star Rating" align="middle" id="4" />
<img class="Rating" src="../../Content/Images/EmptyStar.png" alt="Star Rating" align="middle" id="5" />
and Now you can use your code like this...
<script language="javascript" type="text/javascript">
$(function () {
$("img.rating").mouseover(function () {
giveRating($(this), "FilledStar.png");
$(this).css("cursor", "pointer");
});
$("img.rating").mouseout(function () {
giveRating($(this), "EmptyStar.png");
});
$("img.rating").click(function () {
$("img.rating").unbind("mouseout mouseover click");
// call ajax methods to update database
var url = "/Rating/PostRating?rating=" + parseInt($(this).attr("id"));
$.post(url, null, function (data) {
$("#result").text(data);
});
});
});
function giveRating(img, image) {
img.attr("src", "/Content/Images/" + image)
.prevAll("img").attr("src", "/Content/Images/" + image);
}
</script>

d8064 | train | As taskList is a List<Callable<String>>, executor.invokeAll(taskList) returns a List<Future<String>> containing a Future<String> corresponding to each task in taskList. You need to save that List<Future<String>> so that you can later get at the results of your tasks. Something like this:
List<Future<String>> futureList = executor.invokeAll(tasklist);
String result = futureList.get(0).get() +
futureList.get(1).get() +
futureList.get(2).get();
In addition to InterruptedException, Future.get() can also throw CancellationException and ExecutionException so you need to be prepared to deal with these in your try block.
A: As you have very few number of task, you can create 3 CompletableFutures and stream over it and join it.
CompletableFuture<String> task1 = CompletableFuture.supplyAsync(() -> method1());
CompletableFuture<String> task2 = CompletableFuture.supplyAsync(() -> method2());
CompletableFuture<String> task3 = CompletableFuture.supplyAsync(() -> method3());
String concate = Stream.of(task1, task2, task3)
.map(CompletableFuture::join)
.reduce("", (s1, s2) -> s1 + s2);
System.out.println(concate);
A: Adding on top of @Govinda answer -
You can create Stream of CompletableFutures by using the supplyAsync factory method and complete them by calling CompletableFuture::join and concat by calling Collectors.joining().

d8065 | train | Aren't these answers putting too much emphasis on IO? If you want to intersperse newlines the standard Prelude formula is :
> unlines (map show [1..10])
"1\n2\n3\n4\n5\n6\n7\n8\n9\n10\n"
This is the thing you want written - newlines are characters not actions, after all. Once you have an expression for it, you can apply putStrLn or writeFile "Numbers.txt" directly to that. So the complete operation you want is something like this composition:
putStrLn . unlines . map show
In ghci you'd have
> (putStrLn . unlines . map show) [1,2,3]
1
2
3
A: Try this: mapM_ (putStrLn . show) [1..10]
A: Here is my personal favourite monad command called sequence:
sequence :: Monad m => [m a] -> m [a]
Therefore you could totally try:
sequence_ . map (putStrLn . show) $ [1..10]
Which is more wordy but it leads upto a function I find very nice (though not related to your question):
sequence_ . intersperse (putStrLn "")
Maybe an ugly way to do that but I thought it was cool. | unknown | |
d8066 | train | Your class, PagedCollection, doesn't implement INotifyPropertyChanged.
public class PagedCollection<TEntity> where TEntity : class, INotifyPropertyChanged
What this says is that TEntity must be a class and implement INotifyPropertyChanged.
Try this instead:
public class PagedCollection<TEntity> : INotifyPropertyChanged where TEntity : class, INotifyPropertyChanged
A: You can't call PagedCollection.Get(); like that you have to instantiate something.
A: A change in a property of an object within a regular ObservableCollection does not trigger the CollectionChanged event.
Maybe you could use the TrulyObservableCollection class, derived from the former:
ObservableCollection not noticing when Item in it changes (even with INotifyPropertyChanged)
A: One thing is the ObservableCollection property itself.
When you run the program, it is get once when the view is loaded, and it is set once when you first initialize that property.
After that, when you populate the list, it's not the PropertyChanged event that is fired, since it would be fired only if you assign the whole OC property to another value (usually via Items = new ObservableCollection<TEntity>());
Thus, the event you should be watching is CollectionChanged, which is fired every time you add, remove, swap or replace elements. | unknown | |
d8067 | train | Oracle does not automatically shrink datafiles, which is what a tablespace is made of. Oracle simply marked the space which had been used by user XYZ's segments (tables, indexes, and the like) as free for some other user's segments to use.
SELECT * FROM DBA_OBJECTS WHERE OWNER = 'XYZ'; should demonstrate that user XYZ no longer owns any physical (tables, indexes, clusters) or logical (sequences, procedures, packages, triggers, types) objects in the database.
A: You can shrink datafile, under certain circumstances, with following command:
ALTER DATABASE DATAFILE 'filename2' RESIZE new_size;
Datafile size can be reduced if there is no data at the end of file. See "Managing Tablespaces" for detailed information. | unknown | |

d8071 | train | It depends on which environment you work, but lets assume that this is single-threaded environment. Next, first thought was to create instance attribute to manually assign and retrieve anything. It is will work fine when Player instance is the same for all places.
If not, I suggest to introduce class variable, some sort of cache, that will hold Player#id => <some_obj> reference, and with helper accessors, like Player#some_obj which will query Player for object by self.id.
That way you will be ensured that for all Player with the same Id, some_obj will be the same. Also, you will need to deside, when to empty that class-cache. For Rails, i suppose after_filter is good enough. | unknown | |
d8072 | train | You can convert them to Byte, like this:
var
States : TUpdateStatusSet; // Can be any set, I took this one from DB.pas unit
SetAsAInteger: Integer;
dbs: Pointer; // Here's the trick
begin
States := [usModified, usInserted]; // Putting some content in that set
dbs := @States;
SetAsAInteger := PByte(dbs)^;
//Once you got it, SetAsAInteger is just another ordinary integer variable.
//Use it the way you like.

var
MSG: string;
Inserted, Modified: string;
States: TUpdateStatusSet;
MySet: Byte;

while not ClientDataSet.Eof do
begin
//That's the part that interest us
//Convert that integer you stored in the database or whatever
//place to a Byte and, in the sequence, to your set type.
iSet := Byte(ClientDatasetMyIntegerField);// Sets are one byte, so they
// fit on a byte variable
States := TUpdateStatusSet(iSet);
//Conversion finished, below is just interface stuff
if usInserted in States then
Inserted := 'Yes';
if usModified in States then
Modified := 'Yes';
MSG := Format('Register Num: %d. Inserted: %s. Modified:%s',

d8074 | train | Since you can get the dates in any format, get them in YYYYMMDDHHmmss format. Then get those timestamps in an array. There's not enough information about your system in your question to explain how to do this but just loop through the files pulling out the timestamps and pushing them into an array.
Basically you should have an array like this when you're done:
dates = ['20130719114030',
'20130720114030',
'20130721114030',
'20130722114030',
'20130723114030',
'20130724114030',
'20130725114030',
'20130726114030',
'20130727114030',
'20130728114030'];
Once done, simply sort the array:
dates.sort();
Dates will be in alphanumeric order, which also happens to be chronological order because of our date format. The oldest date will be the first one in the array, so
dates[0] // '20130719114030'
Again, there's not enough information about your system to explain how to delete the file, but perhaps you could loop through the files again to find a matching timestamp, then delete the file.
A: I'm not experienced with Javascript, but my logical progression would be:
Out of the 11 files, find the lowest year
If the same
Out of the 11 files, find the lowest month
[...]
all the way down to second
A: Convert them all to date objects and then compare them. You would only have to do two pass throughs of the list to find the smallest date (one to convert and one to compare)... instead of extracting each snippet and going through the list multiple times.

d8075 | train | I've encountered the same problem you did last week. Unfortunately right now Azure Functions (even 2.x) don't support polymorphism for durable functions. The durable context serializes your object to JSON, but there's no way to pass JSON serialization settings as described here on GitHub. There's also another issue about this specific problem.
In my case I have an abstract base class, but you can use the same approach for your derived types. You can create a custom JSON converter that will deal with picking the correct type during deserialization. So for example if you have this sort of inheritance:
[JsonConverter(typeof(DerivedTypeConverter))]
public abstract class Base
{
[JsonProperty("$type")]
public abstract string Type { get; }
}
public class Child : Base
{
public override string Type => nameof(Child);
}
public class Child2 : Base
{
public override string Type => nameof(Child2);
}
Then you can have your а JSON Converter:
public class BaseDerivedTypeConverter : DefaultContractResolver
{
// You need this to protect yourself against circular dependencies
protected override JsonConverter ResolveContractConverter(Type objectType)
{
return typeof(Base).IsAssignableFrom(objectType) && !objectType.IsAbstract
? null
: base.ResolveContractConverter(objectType);
}
}
public class DerivedTypeConverter : JsonConverter
{
private static readonly JsonSerializerSettings Settings =
new JsonSerializerSettings()
{
ContractResolver = new BaseDerivedTypeConverter()
};
public override bool CanConvert(Type objectType) => (objectType == typeof(Base));
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
JObject jsonObject = JObject.Load(reader);
// Make checks if jsonObject["$type"].Value<string>() has a supported type
// You can have a static dictionary or a const array of supported types
// You can leverage the array or dictionary to get the type you want again
var type = Type.GetType("Full namespace to the type you want", false); // the false flag means that the method call won't throw an exception on error
if (type != null)
{
return JsonConvert.DeserializeObject(jsonObject.ToString(), type, Settings);
}
else
{
throw new ValidationException("No valid $type has been specified!");
}
}
public override bool CanWrite => false;
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) => throw new NotImplementedException();
}
In my usage when I call context.GetInput<Base>() I can get either Child or Child1 because Base is abstract.
In your case it can be Book or Student depending on what's the actual value. This also applies for other durable function operations like like
var foobar = await context.CallActivityAsync<Base>("FuncName", context.GetInput<int>());
The converter will deal with that and you'll get the object you want inside foobar.
A: Per my understanding, the class Textbook extends Book, so "Book" is parent class and "Textbook" is subclass. In your context, you want to turn the child class(Textbook) to the parent class(Book). After that, "book" will just have the attribute "title" which is their common attribute but doesn't have the specific attribute "classfor". You can refer to the code below:
A: Tracked the updates to pass in Json serialization to Azure Functions here showing that it will be in v2.1! | unknown | |
d8076 | train | Both are approaches are similar but there is a big difference between
Usability
*
*Class OnCompleteListenerImpl is reuseable, you need not override the same object multiple places
*You need to be careful while initializing OnCompleteListenerImpl object, as you can initialize in multiple ways, you have to be careful with its scope.
*You need not create a new implementation class if you are going with an anonymous approach.
In summary, there are different use cases for both the approaches it is up to you which one you want to follow. For clean code and reusability, we go with implementation class but in case of secure and single instance use, you can go with anonymous class approach. | unknown | |

d8080 | train | The number of reads in Firestore is always equal to the number of documents that are returned from the server by a query. Let's say you have a collection of 1 million documents, but your query only returns 10 documents, then you'll have to pay only 10 document reads.
If your query yields no results, according to the official documentation regarding Firestore pricing, it said that:
Minimum charge for queries
There is a minimum charge of one document read for each query that you perform, even if the query returns no results.
Those unexpected reads most likely come from the fact that you are using the Firebase console. All operations that you perform in the console are counted towards the total quota. So please remember to not keeping your Firebase console open, as it is considered another Firestore client that reads data. So you'll be also billed for the reads that are coming from the console. | unknown | |

*maxRssBytes - maximum process RSS size over which incoming requests are rejected with an HTTP Server Timeout (503) response. Defaults to 0 (no limit).
*maxEventLoopDelay - maximum event loop delay duration in milliseconds over which incoming requests are rejected with an HTTP Server Timeout (503) response. Defaults to 0 (no limit).

d8083 | train | Style it as a table row, set width to 100% for both the table and the “active” cell, and prevent line breaks inside cells. Demo: http://jsfiddle.net/yucca42/jyTCw/1/
This won’t work on older versions of IE. To cover them as well, use an HTML table and style it similarly.
A: If you are fine with css3, you could use box-flex property.
box-flex property specifies how a box grows to fill the box that contains it.
Try this,
#menu {
width: 100%;
padding: 0;
list-style: none;
display: -moz-box; /* Mozilla */
-moz-box-orient: horizontal; /* Mozilla */
display: -webkit-box; /* WebKit */

display: box;
box-orient: horizontal;
}
.active {
-moz-box-flex: 1; /* Mozilla */
-webkit-box-flex: 1; /* WebKit */
box-flex: 1;
}
A: No. You have to add some JS that will monitor window size changes and adjusts your element accordingly.
A: Instead of giving widths in px, set the widths in percentages.
So you could have the non-active each be 10%, and the active will be give a width of 70% | unknown | |
d8084 | train | You'll need to use a loop:
for file in files:
assert Path(file).exists(), f"{file} does not exist!"
In Python 3.8+, you can do it in one line by using the walrus operator:
assert not (missing_files := [n for n in files if not Path(n).exists()]), f"files missing: {missing_files}"
A: n from comprehension isn't in scope where you do f'{n}'
You can show all not exists files
not_exists = [f for f in files if not Path(f).exists()]
assert not not_exists, f'Files {not_exists} not exist'
Or, only the first one
for f in files:
assert Path(f).exists(), f'{f} not exists'
A: As already pointed out in comments, assert is strictly a development tool. You should use an exception which cannot be turned off for any proper run-time checks; maybe create your own exception for this. (Assertions will be turned off in production code under some circumstances.)
Secondly, the requirement to do this in a single line of code is dubious. Code legibility should trump the number of lines everywhere, except possibly in time-critical code, where execution time trumps both.

add_column :users, :properties_count, :integer, :default => 0
User.reset_column_information
User.find(:all).each do |u|
User.update_counters u.id, :properties_count => u.properties.length
end
end
Then you can fetch user which have max properties_count
User.maximum("properties_count")
Here is an awesome RailsCast about counter_cache
A: To find the user with min properties you can simply do,
User.joins(:properties).group("properties.user_id").order("count(properties.user_id) desc").last
And to find the user with max properties,
User.joins(:properties).group("properties.user_id").order("count(properties.user_id) desc").first
Note: Because its a join operation with properties, so user with no properties will not appear in this query.
A: I think you can do like this by scopes
class User
has_many :properties
scope :max_properties,
select("users.id, count(properties.id) AS properties_count").
joins(:properties).
group("properties.id").
order("properties_count DESC").
limit(1)
scope :min_properties,
select("users.id, count(properties.id) AS properties_count").
joins(:properties).
group("properties.id").
order("properties_count ASC").
limit(1)
And just call User.max_properties and User.min_properties
UPDATED:
It will aslo work like BoraMa suggeted
class User
has_many :properties
scope :max_properties,
select("users.*, count(properties.id) AS properties_count").
joins(:properties).
group("users.id").
order("properties_count DESC").
limit(1)
scope :min_properties,
select("users.*, count(properties.id) AS properties_count").
joins(:properties).
group("users.id").
order("properties_count ASC").

d8088 | train | The graphConnection.addRequest is an asynchronous function and you are trying to synchronously return the array of strings back. This won't work because the graphConnection.addRequest is done in the background to avoid blocking the main thread. So instead of returning the data directly make a completion handler. Your function would then become this:
func fbGraphCall(completion: ([String]) -> Void, errorHandler errorHandler: ((NSError) -> Void)?) {
if (FBSDKAccessToken.currentAccessToken() != nil) {
// get fb info
var userProfileRequestParams = [ "fields" : "id, name, email, about, age_range, address, gender, timezone"]
let userProfileRequest = FBSDKGraphRequest(graphPath: "me", parameters: userProfileRequestParams)
let graphConnection = FBSDKGraphRequestConnection()
graphConnection.addRequest(userProfileRequest, completionHandler: { (connection: FBSDKGraphRequestConnection!, result: AnyObject!, error: NSError!) -> Void in
if(error != nil) {
println(error)
errorHandler?(error!)
} else {
var fbData = [String]() // Notice how I removed the empty string you were putting in here.
// DEBUG
println(result)
let fbEmail = result.objectForKey("email") as! String
// DEBUG
println(fbEmail)
fbData.append("\(fbEmail)")
let fbID = result.objectForKey("id") as! String
if(fbEmail != "") {
PFUser.currentUser()?.username = fbEmail
PFUser.currentUser()?.saveEventually(nil)
}
println("Email: \(fbEmail)")
println("FBUserId: \(fbID)")
completion(fbData)
}
})
graphConnection.start()
}
}
I added the completion handler and the error handler blocks that get executed according to what's needed.
Now at the call site you can do something like this:
fbGraphCall( { println($0) // $0 refers to the array of Strings retrieved }, errorHandler: { println($0) // TODO: Error handling }) // Optionally you can pass `nil` for the error block too incase you don't want to do any error handling but this is not recommended.
Edit:
In order to use the variables you would do something like this at the call site
fbGraphCall( { array in
dispatch_async(dispatch_get_main_queue(), { // Get the main queue because UI updates must always happen on the main queue.
self.fbIDLabel.text = array.first // array is the array we received from the function so make sure you check the bounds and use the right index to get the right values.
self.fbEmailLabel.text = array.last
})
}, errorHandler: {
println($0)
// TODO: Error handling
}) | unknown | |
d8089 | train | You can generate the select form:
<?php
$req = $pdo->query('SELECT * FROM table');
$rep = $req->fetchAll(); ?>
<select>
foreach($rep as $row) { ?>
<option value="<?= $row['country'] ?>"><?= $row['country'] ?></option>
<? } ?>
</select>
<?php foreach($rep as $row) {
<input style="display:none" id="<?= $row['country'] ?>" value="<?= $row['capital'] ?>" />
<?php } ?>
So you will have the select with all country, and an input for each Capital with their Country as id, so you can display it with javascript: (jQuery example)
<script>
$('select').change(function() {
$('input:visible').toggle();
$('input[id='+$(this).val()+']').toggle();
});
</script>
A: You can fetch the countries and ther capitals from the database using the following code in php
//This is where you put the fetched data
$entries = Array();
//Make new connection
$connection = new mysqli("127.0.0.1", "username", "password", "databasename");
//Create prepared statement
$statement = $connection->prepare("SELECT `country`, `capital` FROM `table`");
$statement->bind_result($country, $capital);
//Put the fetched data in the result array
while($statement->fetch()) {
$entry = Array();
$entry['country'] = $country;
$entry['capital'] = $capital;
$entries[] = $entry;
}
//Close the statement and connection
$statement->close();
$connection->close();
Next, you make the HTML select objects. It's important that the order of countries remains the same as the order of the capitals.
<!-- Country selection -->
<select id="select-country">
<?php $i = 0;
foreach ($entries as $c) { ?>
<option data-country="<?php echo $i++; ?>"><?php echo $c['country'] ?></option>
<?php } ?>
</select>
<!-- Capitals select -->
<select id="select-capital">
<?php $i = 0;
foreach ($entries as $c) { ?>
<option data-capital="<?php echo $i++ ?>"><?php echo $c['capital'] ?></option>
<?php } ?>
</select>
Finally, you add an event listener to the select with the id of select-country where you listen for the change event. Once called, you change the selected index of the second select to that of the first. That's why it's important that the order remains the same.
<script>
document.getElementById('select-country').addEventListener('change', function () {
document.getElementById('select-capital').getElementsByTagName('option')[this.selectedIndex].selected = true;
});
</script> | unknown | |

d8097 | train | I've ran into the same problem a few times; you can, but you'll have to index each by itself (not all in one hash like you've done). But you could through the whole thing in the value for emit. It can be fairly inefficient, but gets the job done. (See this link: View Snippets)
I.e.:
function(doc) {
if (doc.type=="Employee") {
emit(["EID",doc.values.EID], doc.values);
emit(["FirstName", doc.fName], doc.values);
emit(["LastName", doc.lName], doc.values);
emit(["Designation", doc.designation], doc.values);
emit(["Department", doc.department], doc.values);
emit(["ReportingTo", doc.reportingTo], doc.values);
emit(["Active", doc.isActive], doc.values);
}
}
This puts all "EID" things in the same part of the tree, etc., I'm not sure if that is good or bad for you.

d8098 | train | Same instance would mean any call (from anywhere) to getBean() from ApplicationContext or BeanFactory will land you with the same instance, i.e. constructor is called just once when Spring is being initialized (per Spring container).
However, there are scenarios when you would want different object instances to work with.
For example, if you have a Point object as a member variable in a Triangle class, in case of Singleton, when the Triangle class is being instantiated, the Point object also is instantiated as it is dependent.
If you require a different instance of Point to work with elsewhere, then you will need to define the Point as a prototype, else it carries the same state.
Googling would surely help you find answers and examples demonstrating the use case.
Hope this helps.
A: In case if the same instance is injected everywhere as Singleton, you can use it's shared state for containing any kind of data. In case if new instance is created any time bean is being injected - it's state is not shared. By default all beans are Singletons. Prototype scope stands for cases when bean's inner data should be unique for each place you inject bean into.
Example: you have the bean which represents REST client. Different parts of application use different REST services, each requires some specific request headers - for security purposes, for example. You can inject the same REST client in all these beans to have it's own REST client bean with some specific headers. At the same time you can configure client's politics in common for the whole application - request timeouts, etc.
See also: When to use Spring prototype scope?
A: It helps in designing a software, refer java design patterns you fill find much useful information, In case of singleton you will be able to create only object, it will helps cases like 1.saving time in creating a very complex object (we can reuse the same object) 2.Some times we need to use the same object throughout the application E.g if you want count the total number of active users in the application, you can use singleton object to store it, because there will be only one object so you can easily update and retrieve data. In case of Prototype it will always give you different object, it is necessary in some cases like some access token, you should always get the new /valid token to proceed further, so prototype pattern /Bean is useful.
A: My understanding for Singleton is more likely used in the situation like return single Utility instance.
//SomeUtil is Singleton
var util = SomeUtil.getInstance();
print(util.doTask1());
print(util.doTask2());
If another thread goes into these code, SomeUtil.getInstance() just return the SomeUtil instance other than creating a new one (which might cost much to create a new one).
As to Prototype, I just found this situation using Prototype:
Lets understand this pattern using an example. I am creating an entertainment application that will require instances of Movie,
Album and Show classes very frequently. I do not want to create their instances everytime as it is costly.
So, I will create their prototype instances, and everytime when i will need a new instance,
I will just clone the prototype.

3) Change Permissions From 755 TO 777(Please Make Sure That 777 permission to all in side folder's under wp_content)
4) Than Try to Upload File Agin and its'done
A: If you checked the permission then try this solution :
Please login to the wordpress dashboard ( http://www.domainname.com/wp-admin ) and access the Miscellaneous settings. Find the uploads path specified, it will most likely be specified as:
"/wp-content/uploads/
Change it to read
"wp-content/uploads/
A: change your wp-content folder's writing permission
Step 1: Open your File Manager and navigate to the file or folder that you need to change.
Step 2: Click on the name of the file or folder.
Step 3: Click on the Change Permissions link in the top menu of the File Manager page.
Step 4: Click on as many check boxes as you require to create the right permission. The permission numbers underneath the check boxes will update automatically.
Step 5: Click on the Change Permissions button when you are ready. The new permission level is saved and the display updated to show the modified file.
A: Some time when you upload image so this issue arise just try to change permission level to 744 but select only for directories and try to change the permission level to 644 this time for files hope this will works for you . | unknown | |
