d4104 | train | Did you try checking out first if there actually are so many clusters in your data as you trying to find ? Simply increasing the number of samples does not necessarily mean that the number of clusters will increase as well. If no. of clusters you are giving as input to the algorithm is greater than the actual no. of clusters in the dataset, then it is possible that the algorithm may not converge properly, or the the clusters may simply overlap (completely) over each other.
To find the optimal no. of clusters for your dataset, we use a technique called as elbow method. There are different variations of this method, but the main idea is that for different values of K (no. of clusters) you find the cost function that is most appropriate for you application (Example, Sum of Squared distance of all the points in a cluster to it's centroid for all values of K say 1 to 8, or any other error/cost/variance function. Based on the function you have chosen , you will see that after a certain point, the difference in the values will be negligible. The idea is that we chose that value of 'K' at which the value of the chosen cost function changes abruptly.
For the value K=4 the variance is changing abruptly. So K=4 is the chosen to be an appropriate value.

There are several other methods on cluster validation as well. There exists several packages in R specifically for this purpose.

*Means that the as.vector(x) operation resulted in one or more elements of x being converted to NA as the conversion for those components is not defined.
*When mean.default is called, x is neither numeric or logical and hence the function can't do anything with the data
*Means that x or mx or both are factors and - (and other mathematical operators) is not defined for factor objects.
*See 1. above.
All point to an issue with the input data, usually a factor has been created.
The warnings come from this line:

Warning messages:
1: In var(as.vector(x), na.rm = na.rm) : NAs introduced by coercion
2: In mean.default(x) : argument is not numeric or logical: returning NA
3: In Ops.factor(x, mx) : - not meaningful for factors
4: In var(as.vector(x), na.rm = na.rm) : NAs introduced by coercion
This is because x$Country is a factor:

d4106 | train | I found the answer myself. What I mean by not working was that the divider was clickable. What I had to do was to override in my adapter the areAllItemsEnabled method to return false and create a condition in the isEnabled method (see the second half of the original question).
A: I think the issue you are having is related to the ClickListener you are adding, since you are are putting in the XML that wont be clickable but after you set your ContentView you are putting this line:
list.setOnItemClickListener(new OnItemClickListener() { ... }
wich makes the list clickable.
A: Redering to my answer of another post, you just have to set the OnClickListener on the View that shouldn't be clickable to null. So you would call: view.setOnClickListener(null). Of course you need the reference to the view to do this... | unknown | |

d4108 | train | If ProductName is a form field that you intend displaying on the form, why not instead abstract all the fields of property into a separate Product entity. This should ease the maintenance of your app (and bring it more in line with patterns like MVC / MVVM), e.g.

public string ProductName{ get; set; }

Edit :
IMO, the architecture presented by Rod Cerata's blog looks OK, but I believe it would be improved via encapsulation of a "ViewModel" for your Employee.
Have a look at EmployeePresenter.cs - you get lots of repetitive scraping code like this:
_model.EmployeeID = _view.EmployeeID;
_model.Lastname = _view.Lastname;
_model.Firstname = _view.Firstname;
_model.EmployeeType = _view.EmployeeType;
_model.Salary = _view.Salary;
_model.TAX = _view.TAX;
IMO would be improved by creating a new EmployeeViewModel class (which would be more or less the same as EmployeeModel, plus any 'screen' specific fields e.g. Title, "mode" (Edit, New, Read Only etc), and then using a tool like AutoMapper, which would reduce the code above.
A: 1. Yes, simply use the new keyword, like public new string ProductName { get; set; }
2. No, it simply returns the name of the assembly.
3. Its used for debugging and some "reflection". I say "reflection" because it's more like a human-made reflection.
So, it's safe to go forward this way. But why don't you simply change it to MyCompanyProductName?
Regards
A: Using the 'new' keyword will suppress the warning. When you do this, the result of calling the ProductName property depends on Type of the variable that is used to referenced the form... for example, if you're calling the property from another class:
// Notice that we're only creating one object and
// assigning it to two different variables.
FormInventory explicitlyNameForm = new FormInventory();
Form referenceToBaseForm = explicitlyNameForm;
// Acting on the child reference (FormInventory) will
// operate on YOUR implementation of ProductName
explicitlyNameForm.ProductName = "Some Value";
// But acting on the parent reference (Form) will
// operate on the .NET implementation of ProductName
referenceToBaseForm.ProductName = "Some Other Value";
The end result will probably be what you want... the compiler knows which implementation to use based on how you've declared your variable. And since all references within the .NET framework reference the Form class, not your new class, there is no risk of affecting anything that happens within the .NET framework with respect to this property.
However, as the others have suggested, it may cause less confusion if you're able to rename the property. | unknown | |

d4113 | train | Delegates are immutable. You never change a delegate. Any method that appears to mutate a delegate is in fact creating a new instance.
Delegates are immutable; once created, the invocation list of a delegate does not change.
There is thus no cause for concern that the invocation list may be updated whilst a delegate is being invoked.
What you do have to guard against, however, and have failed to do in your method is when the delegate may in fact be null.
(new MyContext()).Go();
will cause an exception. You used to have to guard against this by reading the value into a local variable, testing it for null and then invoking using it. It can now more easily be resolved as:
public void Go()
{
_multicastDelegate?.Invoke(this);
}
A: The definition of thread-safe as used by MSDN documentation means code that is properly synchronized. It usually doesn't state on what it synchronizes, but it can be the class object for static members, the instance object for instance members, or it can be some inner object, such as SyncRoot in many collection types.
Although delegates are immutable, you must still synchronize properly. .NET and C#, unlike Java, don't guarantee safe publication, so if you don't guarantee synchronization, you can observe a partially initialized object in other threads1.
To turn your code thread-safe, you just need to use _lock when reading from the delegate field as well, but you can call Invoke outside the lock, landing onto the delegate the responsibility to keep its own thread safety.
public class MyContext
{
private readonly object _lock = new object();
public delegate bool MyDelegate(MyContext context);
private MyDelegate _delegate;
public MyContext()
{
}
public void AddDelegate(MyDelegate del)
{
lock (_lock)
{
_delegate += del;
}
}
public void RemoveDelegate(MyDelegate del)
{
lock (_lock)
{
// You had a bug here, +=
_delegate -= del;
}
}
public void Go()
{
MyDelegate currentDelegate;
lock (_lock)
{
currentDelegate = _delegate;
}
currentDelegate?.Invoke(this);
}
}

*Microsoft's .NET Framework implementation always makes volatile writes (or so they say), which kind of gives you safe publication implicitly, but I personally don't rely on this. | unknown | |

d4115 | train | In order to execute the server-side script (PHP) from the client side (static HTML and JavaScript), you need to use the Ajax technology. In essence, Ajax will allow you to send and/or retrieve data from the server "behind the scenes" without affecting your page.
JavaScript, a client-side scripting language used to add interactivity to your webpage, already supports Ajax. However, the syntax is rather verbose, because you need to account for differences across browsers and their versions (Internet Explorer version 5 up to 11 in particular have their own implementation different from Chrome or Mozilla).
You, as a developer, can avoid these technicalities by using a front-end framework such as jQuery (other good examples are Angular.js, Vue.js, and others). jQuery is essentially a library of code written in vanilla JavaScript that simplifies common tasks such as querying DOM. It also provides expressive syntax for using Ajax. It will resolve browser incompatibilities internally. This way you can focus on your high-level logic, rather than low-level issues like that.
Once again, jQuery code is also JavaScript code. So place the following <script> tag, as you would normally do with JS, somewhere in your page.
<script>
$( document ).ready(function() {
$("form").submit(function(e) {
e.preventDefault(); // prevent page refresh
$.ajax({
type: "POST",
url: "jump_invoicepaid.php",
data: $(this).serialize(), // serialize form data
success: function(data) {
// Success ...
},
error: function() {
// Error ...
}
});
});
});
</script>
First, this code will run once the page is loaded. Second, it will attach a submit event handler to every <form> in your HTML page. When you click on the <button type='submit'>, this event will fire. e.preventDefault() will halt the normal submission of the form and prevent page refresh. Note that e is the event object that contains info about the submit event (such as which element it originated from).
Next, we are sending the actual Ajax request using $.ajax method from jQuery library. It is a generic method, and we could as well have used $.post, since we are specifically doing the POST request. It will be received by your PHP file jump_invoicepaid.php.
Now, in your PHP file, you have the following line: header('Location: ./?page=pastevents'); which forces a redirect to the home page with a GET parameter. If you want to have the same behavior, then you would need to remove that line, and put window.location.replace("/?page=pastevents") to your JavaScript code:
// in your Ajax request above...
success: function(data) {
window.location.replace("/?page=pastevents");
},
This would refresh the page however, because you are essentially requesting the home page with a GET method. I am guessing that this is done in order to update information on the page. You could do so without redirecting, by adding / changing / removing elements on your page (i.e. in DOM). This way, you would send data from the server back to the client, and if the response is received successfully, in your JavaScript you can obtain that response and manipulate your webpage accordingly.
If the latter interests you, then consider using JSON format. You just need to do json_encode in your PHP, and then on the client-side, parse the JSON string using JSON.parse(...). Read on here for example.
Hope this helps! | unknown | |

d4117 | train | Just a heads-up. You are declaring pin 2 twice, first as interruptPin, then as soundSensor. This might be prone to confusion and misfiring of the ISR
Inside your interrupt function, you should wrap your logic inside cli(); and sei(); to avoid false triggering during the interruption. Do not use detachInterrupt().
Review the documentation from avr/sleep.h (here). As it reads, you MUST make sure that interrupts are enabled before sending the CPU to sleep. I believe you are missing a sei() before sending the CPU to sleep
I would advise you to use an external (strong) pull-up to guarantee that pin 2 won't be triggered unless is via the sensor.
Finally, please observe that according to your logic, the interrupt service will be called any time the pin goes LOW. This will override the else from the conditional inside the loop() (at least this will occur after the first time you call the (mispelled) function Goint_to_sleep()).
Think of another approach to accomplish what you want. Just be careful with the ISRs that you implement
EDIT: I forgot to mention something extremely important:
You need to be absolutely sure that the output signal from the microphone that you are connecting to is above the threshold for a digital signal (~2.60-2.8V). Having said that, are you sure that the interrupt edge detection should be LOW when clapping? I think it must be high in which case the pin should be pulled low. You can always reverse this logic and amplify the signal with an external transistor to convert the sensor's signal into an adequate digital pulse | unknown | |

d4119 | train | Try this :
select * from (
SELECT * FROM items WHERE duration = 5
UNION
SELECT * FROM items WHERE duration = 10
) odrer by date DESC
A: When you use UNION OR UNION ALL order by not allowed in each select statement. You have to apply order by in outer select statement.
A: Order the UNION result by duration first, then date desc.
select *
from
(
SELECT * FROM items WHERE duration = 5
UNION
SELECT * FROM items WHERE duration = 10
)
order by duration, date DESC
However, there's no need for a UNION (see e4c5's answer).
A: If I understood you from the comments, you want something like this?
SELECT s.* FROM (
SELECT i.*,1 as ord_col FROM items i WHERE duration = 5
UNION
SELECT it.*,2 FROM items it WHERE duration = 10) s
ORDER BY CASE WHEN s.ord_col = 5 THEN s.date
ELSE '1000-01-01'
END DESC
Although this query is inefficient , you can do it with one select :
SELECT i.* FROM items i WHERE i.duration IN(5,10)
ORDER BY CASE WHEN s.ord_col = 5 THEN s.date
ELSE '1000-01-01'
END DESC
If its not dynamic, and 5 will be ordered before 10 and these are constant values , you can simply add the duration column to the query , ORDER BY duration,date although this will also order the second query be date, just after the first one.
A: I think you don't even need to UNION at all and you can refactor your query this way:
SELECT *
FROM items
WHERE duration IN (5, 10)
ORDER BY CASE
WHEN duration = 5 THEN 1
WHEN duration = 10 THEN 2
ELSE NULL
END
, CASE
WHEN duration = 5 THEN [date]
ELSE NULL
END DESC;
This query will sort based on your duration first (the ones with 5 will come first, with 10 second) and then as a second order option it will sort ones with duration = 5 by date in descending order.

d4120 | train | You may try writing it like f = Quiet[Check[#1^#2,1]] &.
Quiet will suppress the "Power::indet: "Indeterminate expression 0^0 encountered." message and Check will replace the result with 1 if it is indeterminate.
It is probably better to use some function like s = Quiet[Check[#1, 1]] and wrap your expressions in it.
A: I'm slightly surprised the trivial (albeit slightly dangerous) fix did not get mentioned earlier. If you really don't expect the expression 0^0 to come up in any context where you'd (a) be worried that it did, or (b) would like it to evaluate it to something other than 1, you can simply try
Unprotect[Power];
Power[0, 0] = 1;
Protect[Power];
0^0
I needed this fix in a situation where a complicated function had a number of calls to expressions of the form x^n where x is real and n is an integer, in which case 0^0 should be seen as the limit of x^0=1 as x goes to 0.
It's important to note, though, that doing this will 'contaminate' Power for the current kernel session, and may therefore break other notebooks which run concurrently and for which conditions (a) and (b) may not hold. Since Power is located in the Systemี context instead of Globalี, it may be difficult to separate the contexts of different notebooks to avoid clashes produced by this fix.
A: Of course there are many ways to do things in Mathematica, but a design idiom I often use is to write the "function" (actually, a pattern) with decreasing specificity. Mathematica has the property that it will apply more specific patterns before less specific.
So, for your case I'd just write:
Clear[f];
f[0, 0] = 1;
f[a_, b_] := a^b;
I assume you expect to work with integer values since that's the usual context for this type of situation, e.g. when evaluating Bernstein basis functions.
A: I agree with the answer of @Deep Yellow, but if you insist on a pure function, here is one way:
f = Unevaluated[#1^#2] /. HoldPattern[0^0] :> 1 &
EDIT
Staying within the realm of pure functions, the situation you described in your edit can be addressed in the same way as my solution to your specific original example. You can automate this with a tiny bit of metaprogramming, defining the following function transformer:
z2zProtect[Function[body_]] :=
Function[Unevaluated[body] /. HoldPattern[0^0] :> 1]
Then, my previous code can be rewritten as:
f = z2zProtect[#1^#2 &]
But you can is this more generally, for example:
ff = z2zProtect[#1^#2 + 2 #2^#3 + 3 #3^#4 &]
In[26]:= ff[0,0,0,0]

Observe that there are two entries for the pt_ssn : 5678. This is because they are for different dates.
Hope this helps!!!
A: I am guessing there is a patient record even if there is no claim.. so the left join should be the other order.
Try this (or even list the fields you want returned):
SELECT distinct *
FROM PATIENT left join CLAIM
on claim.pt_ssn = Patient.pt_ssn
and CLAIM.emp_ssn = Patient.emp_num
WHERE CLAIM.FROM_DATE < Patient.eff_date; | unknown | |
d4124 | train | The issue was I had misplaced the return statement. I still have much fine-tuning to do, but the following code solves the issue in the question that I posed earlier today.

d4125 | train | When you drop the button into the table, does the 'print position' work? It should be printing out the coords of the drop position to your shell.
I think you need to use those to then insert the button into the table.
Got it working - change your drop event to this:
position = e.pos()
print position
row = self.rowAt(position.y())
column = self.columnAt(position.x())
self.setCellWidget(row,column,self.butObject)
e.setDropAction(QtCore.Qt.MoveAction)
e.accept()

d4127 | train | A global variable is a variable that is declared at the top level in a file. So if we had a class called Bar, you could store a reference to an instance of Bar in a global variable like this:
var bar = Bar()
You would then be able to access the instance from anywhere, like this:
bar
bar.foo()
A shared instance, or singleton, looks like this:
class Bar {
static var shared = Bar()
private init() {}
func foo() {}
}
Then you can access the shared instance, still from anywhere in the module, like this:
Bar.shared
Bar.shared.foo()
However, one of the most important differences between the two (apart from the fact that global variables are just generally discouraged) is that the singleton pattern restricts you from creating other instances of Bar. In the first example, you could just create more global variables:
var bar2 = Bar()
var bar3 = Bar()
However, using a singleton (shared instance), the initialiser is private, so trying to do this...
var baaar = Bar()
...results in this:
'Bar' initializer is inaccessible due to 'private' protection level
That's a good thing, because the point of a singleton is that there is a single shared instance. Now the only way you can access an instance of Bar is through Bar.shared. It's important to remember to add the private init() in the class, and not add any other initialisers, though, or that won't any longer be enforced.
If you want more information about this, there's a great article by KrakenDev here.
A: Singleton (sharing instance)
Ensure that only one instance of a singleton object is created & It's provide a globally accessible through shared instance of an object that could be shared even across an app.

d4138 | train | First off, there's lots of different home screen implementations on Android. The stock Android one, Samsung, HTC and Motorola all have their own variants, then third party ones like Launcher Pro. All use different stores as to what to keep on the home screen, may provide different profiles for the home screen (home, work, etc).
Second, the home screen is prime real estate. And it is also the user's real estate.

d4139 | train | A nicer (IMHO) way to do this would be to define your custom domains in .env files โ this way it's clear that domain names are environment-specific and there won't be a need for any 'ifs':
.env:
URL=www.dev.co.uk
SUBDOMAIN1=blog.dev.co.uk
SUBDOMAIN2=careers.dev.co.uk
Then add to config/app.php:
'url' => env('URL'),
'subdomain1' => env('SUBDOMAIN1'),
'subdomain2' => env('SUBDOMAIN2'),
routes.php would become simpler and nicer to read:
Route::group(['domain' => Config::get('app.url')] {}
Route::group(['domain' => Config::get('app.subdomain1')] {}
Route::group(['domain' => Config::get('app.subdomain2')] {}
PS. Imagine if you get more environment-specific URLs in the future โ your routes.php will get bloated and it will (it already does, actually) contain environment-specific data which is not nice! | unknown | |

d4141 | train | Disable (or don't enable - doesn't it require you to set a define?) the automatic linking. | unknown | |
d4142 | train | There seems to be a couple things wrong with the code. As it is posted I would be surprised if it compiles.
In your Adapter you have:
List<Order> myfoods;
and
public AllOrdersAdapter(List<Order> myfoods) {
this.myfoods = myfoods;
}
but in your activity code you pass:
adapter = new AllOrdersAdapter((ArrayList<String>) myfoods);
one is a ArrayList of String the other of Order !
You also need to change your adapter class to something like:
public class AllOrdersAdapter extends RecyclerView.Adapter<AllOrdersAdapter.AllOrdersViewHolder> {
private static final String TAG = AllOrdersAdapter.class.getSimpleName();
private ArrayList<Order> mData;
public class AllOrdersViewHolder extends RecyclerView.ViewHolder {
public TextView mTvFoodname;
public TextView mTvFoodQuantity;
public TextView mTvFoodId;
public AllOrdersViewHolder(View v){
super(v);
// TODO: You need to assign the appropriate View Id's instead of the placeholders ????
mTvFoodQuantity = v.findViewById(R.id.????);
mTvFoodname = v.findViewById(R.id.????);
mTvFoodId = v.findViewById(R.id.????);
}
}
public AllOrdersAdapter(ArrayList<Order> data){
this.mData = data;
}
@Override
public AllOrdersViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.business_list_card_view, parent, false);
return new AllOrdersViewHolder(itemView);
}
@Override
public void onBindViewHolder(final AllOrdersViewHolder holder, final int position){
//TODO: You need to decide whether you want to pass a string or order object
Order data = mData.get(position);
final String name = data.getProductName();
final String quantity = data.getQuantity();
final String id = data.getProductId();
holder.mTvFoodname.setText(name);
holder.mTvFoodQuantity.setText(quantity );
holder.mTvFoodId.setText(id)
}
@Override
public int getItemCount(){
return mData.size();
}
}
Note: That since I can not know, whether an ArrayList of String or of Order should be used the parameters in either the Activity or Adapter will need to be changed. Also how you assign the data to the RecyclerView will be affected in the onBindViewHolder method.
You should also follow the advice given by Frank.
EDIT
Change your onDataChange() method to this:
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
if (postSnapshot.getValue() != null) {
List ingredients = new ArrayList<>();
for (DataSnapshot ing : postSnapshot.child("foods").getChildren()) {
String name = ing.child("productName").getValue(String.class);
String quantity = ing.child("quantity").getValue(String.class);
String productId = ing.child("productId").getValue(String.class);
// Using your overloaded class constructor to populate the Order data
Order order = new Order(productId, name, quantity);
// here we are adding the order to the ArrayList
myfoods.add(order);
Log.e(TAG, "Gained data: " + name)
}
}
}
adapter.notifyDataSetChanged();
}
In your Activity you will need to change the ArrayList class variable "myfoods" to this:
ArrayList(Order) myfoods = new ArrayList<>();
and in your onCreate() method you can now change:
adapter = new AllOrdersAdapter((ArrayList<String>) myfoods);
to simply this:
adapter = new AllOrdersAdapter(myfoods);
Also notice that I have made some changes in my original code above.
A: You'll want to create the adapter, and attach it to the view, straight in onCreate:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
//firebase
db = FirebaseDatabase.getInstance();
requests= db.getReference().child("Requests");
lstFoods = (RecyclerView)findViewById(R.id.lstAllFoods);
lstFoods.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(this);
lstFoods.setLayoutManager(layoutManager);
adapter = new AllOrdersAdapter((ArrayList<String>) myfoods);
lstFoods.setAdapter(adapter);
loadOrders();
}
This also means you should declare myfoods as a ArrayList<String>, which saves you from having to downcast it. Something like:
ArrayList<String> myfoods = new ArrayList<String>();
Now in loadOrders you simple add the items to the list, and then notify the adapter that its data has changed (so that it repaints the view):
private void loadOrders() {
requests.child("foods").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
for (DataSnapshot ing: postSnapshot.getChildren()) {
myfoods.add(ing.child("quantity").getValue(String.class));
myfoods.add(ing.child("productName").getValue(String.class));
myfoods.add(ing.child("productId").getValue(String.class));
}
}
adapter.notifyDataSetChanged();
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
throw databaseError.toException(); // don't ignore errors
}
});

d4151 | train | You can't execute your js method before the elements get loaded. so wrap your code in head/body
check this fiddle
A: Here is a possible solution (no jQuery) : http://jsfiddle.net/wared/A6w5e/.
As you might have noticed, links are not "disabled", I simply save the id of the DIV which is currently displayed in order to check the requested id before toggling : if (current !== id).
Another thing to note is that toggle_visibility is overwritten (only once) inside itself. It might look weird, but it's just a way to create a closure in order to enclose the variable named current inside a private context. The goal is to avoid polluting the parent scope.
Lastly, I've modified the original code to hide all divs except the one targeted by id.
function toggle_visibility(id) {
var current = 'Blue';
(toggle_visibility = function (id) {
var div, l, i;
if (current !== id) {
current = id;
div = document.getElementsByClassName('toggle360');
l = div.length;
i = 0;
for (; i < l; i++) {
div[i].style.display = div[i].id === id ? 'block' : 'none';
}
}
})(id);
}
A: Wrap your code in head or body.
You are executing your code before DOM is created
Fiddle Demo
A: A couple people have commented why it doesn't work in fiddle. To answer the question....
It easy to toggle visibility using jquery if there are only two divs:
$(document).delegate('.flashlinks a', 'click', function () {
$('.toggle360').toggle();
});
I would use a css class to disable the links. Then I would select what to do with the click based on if the class was present:
$(document).delegate('.flashlinks a:not(".disabled")', 'click', function () {
$('.toggle360').toggle();
$('.flashlinks a').toggleClass("disabled");
});
$(document).delegate('.flashlinks a.disabled', 'click', function () {
e.preventDefault();
});
and in my css I would have something like
.disabled {
color: black;
text-decoration:none;

d4158 | train | In the batch_job_execution_context table, you may have some records which are created by the spring batch version 3. While you are trying to execute new execution with spring batch version 4, it trying to compare previous records. So it trying to deserialize those older records. this is why you are getting this issue.
Spring batch version 3 records are like bellow in the batch_job_execution_context table
{"map":[{"entry":{"string":["key","value"]}}]}
Spring batch version 4 records are like bellow in the batch_job_execution_context table
{"key":"value"}
Remove all the records created by version 3. This will fix the issue. | unknown | |
d4159 | train | At first I would recommend you to use $("#outer").innerWidth() when calculating maxCount as in general if you have also a padding in container, you can use only the inner part of the element.
And finally as a solution to your problem I can suggest you to add
box-sizing: border-box;
-moz-box-sizing: border-box;
to the #outer div to maintain its width. Unfortunately this doesn't work as I expect, there is a little more space from rigth side than from left. But there is another strange thing that I don't understand, those white spaces between divs (see the screenshot), I can't find CSS affecting these parts. I think that these spaces are affecting the calculation that's why I get a little more left-padding than we need.
Here is the jsFiddle link
A: Here you go: http://jsfiddle.net/dan_barzilay/fy494/
What i did was instead of changing the #outer padding left to freeSpace / 2 and by that increasing the size only from the left side I changed both padding-right and padding-left by freeSpace / 4 to keep the images in the center.
$("#outer").css({"padding-left": freeSpace / 4, "padding-right": freeSpace / 4}); | unknown | |

Good luck!

$itemsContainer = $('.items-container');
$mainContent = $('.main-content');

$mainHeader = $('.main-header');

var containerH = $container.height();
var headerH = $header.height();
var mainHeaderH = $mainHeader.height();
//assigning new height to main-content class
$mainContent.css("height", (containerH - headerH - mainHeaderH) + "px");
//similar operation for items-container
//creating vars based on jquery objects
$topInfo = $('.top-info');
//calculating heights
var topInforH = $topInfo.outerHeight(); //since in your example top-info has no content only padding, you will need to use the method outerHeight instead of height
//assigning new height to main-content class
$itemsContainer.css("height", (containerH - headerH - topInforH) + "px"); });
By the way, I updated your jsfiddle with my solution, so you can test it.
A: When you use a height of 100% it sets it to the full height regardless of other sibling elements. So they are at 100% of the parent element but then the headers are pushing them down. You will have to use fixed heights on all elements. Or set one to 20% and other to 80% etc.

Code behind cs code
Created a SendMail() function which will fire on buttonclick
Note:- I haven't added validations on the controls, so if you want it you can add as per your requirement.
protected void SendMail()
{
// Gmail Address from where you send the mail
var fromAddress = "[email protected]";
// any address where the email will be sending
var toAddress = txtEmail.Text.ToString();
//Password of your gmail address
const string fromPassword = "Your gmail password";
// Passing the values and make a email formate to display
string subject = txtSubject.Text.ToString();
// Passing the values and make a email formate to display
string body = "From: " + txtname.Text + "\n";
body += "Email: " + txtEmail.Text + "\n";
// smtp settings
var smtp = new System.Net.Mail.SmtpClient();
{
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
smtp.Timeout = 20000;
}
// Passing values to smtp object
smtp.Send(fromAddress, toAddress, subject, body);
}
Now the above function will be called on Button click so that every time you enter the details you can call that function.
protected void btnSubmit_OnClick(object sender, EventArgs e)
{
try
{
SendMail(); // Send mail function to send your mail
txtname.Text = "";
txtEmail.Text = "";
txtmobileno.Text = "";

d4168 | train | I faced the same issue. This article is Gold link
1.In auth route File I had following code
const CLIENT_HOME_PAGE_URL = "http://localhost:3000";
// GET /auth/google
// called to authenticate using Google-oauth2.0
router.get('/google', passport.authenticate('google',{scope : ['email','profile']}));
// GET /auth/google/callback
// Callback route (same as from google console)
router.get(
'/google/callback',
passport.authenticate("google", {
successRedirect: CLIENT_HOME_PAGE_URL,
failureRedirect: "/auth/login/failed"
}));
// GET /auth/google/callback
// Rest Point for React to call for user object From google APi
router.get('/login/success', (req,res)=>{
if (req.user) {
res.json({
message : "User Authenticated",
user : req.user
})
}
else res.status(400).json({
message : "User Not Authenticated",
user : null
})
});
2.On React Side After when user click on button which call the above /auth/google api
loginWithGoogle = (ev) => {
ev.preventDefault();
window.open("http://localhost:5000/auth/google", "_self");
}
3.This will redirect to Google authentication screen and redirect to /auth/google/callback which again redirect to react app home page CLIENT_HOME_PAGE_URL
4.On home page call rest end point for user object
(async () => {
const request = await fetch("http://localhost:5000/auth/login/success", {
method: "GET",
credentials: "include",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
"Access-Control-Allow-Credentials": true,
},
});
const res = await request.json();
//In my case I stored user object in redux store
if(request.status == 200){
//Set User in Store
store.dispatch({
type: LOGIN_USER,
payload : {
user : res.user
}
});
}
})();
5.last thing add cors package and following code in server.js/index.js in node module
// Cors
app.use(
cors({
origin: "http://localhost:3000", // allow to server to accept request from different origin
methods: "GET,HEAD,PUT,PATCH,POST,DELETE",
credentials: true // allow session cookie from browser to pass through
})
);
A: Your authentication should be done server side. Here is how it works.
*
*You make a fetch or axios call to your authentication route.
*Your authentication route sends a request to Google's Authentication servers. This is important to have on the backend because you will need to provide your clientSecret. If you were to store this on the frontend, it would make it really easy for someone to find that value and compromise your website.
*Google authenticates the user and then sends you a set of tokens to your callback url to use for that user (refresh, auth, etc...). Then you would use the auth token for any additional authorization until it expires.
*Once that expires, you would use the refresh token to get a new authorization token for that client. That is a whole other process though.
Here is an example of what that looks like with Passport.js: https://github.com/jaredhanson/passport-google-oauth2
EDIT #1:
Here is an example with comments of the process in use with Facebook, which is the same OAuth codebase:
https://github.com/passport/express-4.x-facebook-example/blob/master/server.js
A: Redux can really help with achieving this and this follows the same logic as Nick B already explained...
*
*You set up oauth on the server side and provide an endpoint that makes that call
*You set up the button on you react frontend and wire that through an action to the endpoint you already setup
*The endpoint supplies a token back which you can dispatch via a reducer to the central redux store.
*That token can now be used to set a user to authenticated
There you have it. | unknown | |
d4169 | train | There is no canonical definition of 'empty value' for either Integer or Date.
You just program what you mean, and 'empty' is not a valid answer to the question 'what do you mean'.
For example: "Empty strings, the 0 integer, and sentinel instant value with epochmillis 0 (Date is a lie. It does not represent dates; it represents instants, and badly at that; use java.time.Instant instead normally)".
Then, you just.. program that:
for (Object obj : result) {
if (obj == null) return false;
if (obj instanceof Date) {
if (((Date) obj).getTime() == 0) return false;
} else if (obj instanceof String) {

It's an if for every type because there is no such thing as CouldBeEmpty as an interface that all these types implement. Said differently, "an empty Date" isn't a thing.
A: This should work. I tried it with a mock array, but I don't know if it is exactly the same as yours:

result[1] = "";
result[3] = 5;
result[4] = LocalDate.now();
result[5] = "string";
boolean listcontainsnullorempty = false;
for(var obj: result){
if(obj == null || obj.equals("")){
listcontainsnullorempty = true;
}
}
System.out.println(listcontainsnullorempty);
}
depending on your list, you might need to add || obj.isEmpty() in the if-clause. | unknown | |
d4170 | train | Both approaches will produce SQL and execute it on the server. The SQL should be similar/identical and performance will be near identical. If you want to see the SQL being produced i suggest you open up the "SQL Server Profiler" and run a Trace! The trace will also show you execution time taken. Side note: Your performance gains will come from correctly configured Table Indexes.
A: I know its old question but i would like to add some info...
Even both are translated to SQL query and executed on SQL Server, the difference in performance will be related to the way that lightSwitch (oData v3) Generate the statement..
Taking in consideration between the following;
1- select * from Table where colA like ('foo')
2- select * from Table where colA = 'foo' TOP(1)
general if colA is primary Key at the table then SQL will stop searching after the first match on the second if just want to retrieve only one ,, and the equal is better performance...

d4172 | train | So for anybody who may be interested about this topic , here is my experience :
We finally decided not to use MYSQL portioning and instead using database sharding.
The reason for that is: no matter how good you implement the portioning there is still the fact that data needs to indexed and brought into the memory when needed and for our system which is handling up to 500,000 user's emails this can simply become a major hardware issue over the time as people receive mail and will force you to buy more expensive hardware .
Also there is another hidden cost in MYSQL which is the altering tables schema which can simply become impossible if you have a big table and limited resources. After using MSSQL and Oracle in real world scenario I was NOT really impressed by the way MYSQL handles metadata updates and indexing.
So the short answer would be do not use portioning for you database unless you are sure that you won't have major schema changes to your table/indexes and also your table will not grow too big.
Although I have to say if you design a good index for your system(be very careful with primary keys because that is your clustered index in MYSQL and your queries will be much more efficient if you query on primary key index) you may not really need portioning at all (right now on one of our installations we have a table with +450,000,000 records and it is very fast when you use the primary key index to query the data)
Another point is if there is a chronology in your data and you always have a date range to query it is good idea to use partitioning if your database does not grow too big and if you are intending to delete the old data after a while (like a log rotation,...) partitioning may be the best option because you can simply drop the partition instead of writing a delete process.
Hope this will help you making the right decision. | unknown | |

d4183 | train | Does std::string's c_str() method always return a null-terminated string?
Yes.
It's specification is:
Returns: A pointer p such that p + i == &operator[](i) for each i in [0,size()].
Note that the range specified for i is closed, so that size() is a valid index, referring to the character past the end of the string.
operator[] is specified thus:
Returns: *(begin() + pos) if pos < size(), otherwise a reference to an object of type T with value charT()
In the case of std::string, which is an alias for std::basic_string<char> so that charT is char, a value-constructed char has the value zero; therefore the character array pointed to by the result of std::string::c_str() is zero-terminated.
A: According to this, the answer is yes.
A: c_str returns a "C string". And C strings are always terminated by a null character. This is C standard.

d4185 | train | You need to change the onchange to
fixOrder()
A: JS Fiddle
Your onchange event is onchange="fixOrder" which is not really doing anything. If you change it to fixOrder() you will call the function fixOrder when the change event is fired.
Furthermore:
*
*I don't think const is a reserved word in JavaScript. I don't think JS has constants. You should change that line from const TAX to var TAX;
*Unlike parseInt, which takes two arguments (string and base/radix), parseFloat only takes one argument (string), so you can remove the , 10 from it
I imagine you want something like:
function fixOrder() {
var TAX = 0.0975;
var numPrice;
var total;
var tax;
numPrice = parseFloat(document.getElementById("cost").value);
tax = parseFloat(document.getElementById("tax").value);
total = parseFloat(document.getElementById("total").value);
numPrice = numPrice + (tax || numPrice * TAX);
total = numPrice;
var dec = new Number((total+'').split('.')[1]) || 0;
total = document.getElementById("total").value =
"$" + Number(parseInt(total)
+ '.'
+ Math.round(
( (dec+''.split('').reverse().join('') )/100 + '').split('').reverse().join('')
)).toFixed(2);
);
if (isNaN(numPrice)) {
alert("Sorry,you must enter a numeric value to place order");
numPrice = 0;
}
}
This will use the dollar amount of tax you enter, or if that doesn't exist, it will use the constant rate that you have supplied at the beginning (this was changed from .975 to .0975).
Also, notice the new calculation from total, we're taking the decimal part of the number, dividing it by 100 to get to two decimal places, reversing it back so it's in the proper order again, and then rounding it to the nearest 1 (cent).
HTML Body:

d4191 | train | This is a known issue with Apache Cordova 6.3.1 and for the Visual Studio tools we've been working on a fix for this. To work around the issue for now, you'll need to perform the following steps:
*
*Add a developmentTeam property to the ios build settings in your project's build.json file (an example is shown below).
*Set the build.json file's codeSignIdentity property to the static value iPhone Developer.
*Setup a before_compile hook in your project to copy the developmentTeam property into the project's platforms/ios/cordova/build.xcconfig file.
The project's build.json file should look something like the following:
{
"ios": {
"debug": {
"developmentTeam": "DEVELOPMENT_TEAM_NAME"
},
"release": {
"developmentTeam": "DEVELOPMENT_TEAM_NAME",
"codeSignIdentity": "iPhone Developer"
}
}
}
To simplify the process, Darryl Pogue published a sample hook that makes the required changes to the project's build.xconfig file based on the build.json example shown above. To use this hook, copy the sample xcode8.js file to your project's hooks folder, and then modify the project's config.xml to execute it before the compilation step using the following code:
<platform name="ios">
<hook type="before_compile" src="hooks/xcode8.js" />
</platform>
Creating a Distribution Build
At this point, the Cordova build process works, and you can run, test and debug your app. Unfortunately, the app isn't being signed with the correct development certificate needed for distribution. In order to sign them with a distribution certificate, you'll need to create an archive of the app by following the instructions found in: Uploading Your App to iTunes Connect.

Developers building Cordova applications for iOS 10 may encounter the following errors:
Http 404: Error mounting developer disk image
Http 500: No devices found to debug. Please ensure that a device is connected and awake and retry.

brew update && brew upgrade libimobiledevice --HEAD && brew upgrade ios-webkit-debug-proxy ideviceinstaller | unknown | |
d4192 | train | First you need to specify proxy pass directive for your api calls - I would propose to add /api in your fetch calls. Than provide upstream using the same name for your backend service as specified in docker-compose.yml. It is important that backend service proceed the web service in docker-compose.yml, otherwise you would get connection error in nginx like this nginx: [emerg] host not found in upstream "backend:8080" You can update your nginx.conf as follows:
upstream backend {
server backend:8080;
}
server {
listen 80;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
try_files $uri $uri/ /index.html =404;
}
location /api {
rewrite /api/(.*) /$1 break;
proxy_pass http://backend;
}
include /etc/nginx/extra-conf.d/*.conf;
}
Or simply in your case provide a proxy pass to localhost as follows:
server {
listen 80;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
try_files $uri $uri/ /index.html =404;
}
location /api {
rewrite /api/(.*) /$1 break;
proxy_pass http://localhost:8080;
}
include /etc/nginx/extra-conf.d/*.conf;
}

RUN rm /etc/nginx/conf.d/default.conf
COPY nginx/nginx.conf /etc/nginx/conf.d
EXPOSE 80

d4193 | train | Seam is mainly an inversion of control (IoC) container that provides a lot of boilerplate functionality for web development. It has no real hard requirements for you to use JPA/Hibernate. It's just that the most usual scenario for Java web development is a database backend that's mapped by an ORM, of which JPA/Hibernate is probably the de-facto standard.
If your data access layer (DAL) does not exist or is just wrapper around an existing API (web services, REST, etc.), Seam will also handle that scenario very easily and provide you with all its remaining functionality (session management, JSF integration, security, navigation flow management and lots more).
In essence, a simple component (or set of) that exposes the API you mention and handles its state should be enough. Then again, I do not know your requirements, so I can't say that for sure.
A more complex example is the Seam Social module in Seam 3. It uses Twitter, Facebook or other social web APIs to connect to those services and inject them into Seam's contexts', so that your application can leverage their functionality. I don't know if your scenario is so complex that it would require you to build an entire CDI module from scratch (as Seam Social does) but take a look at their documentation. It might give you some ideas on what further investigate. | unknown | |
d4194 | train | Yes, your generate SQL is wrong. The query generated is:
SELECT "ingredients".* FROM "ingredients" WHERE (14) LIMIT 1
whereas it should have been:
SELECT "ingredients".* FROM "ingredients" WHERE id = 14 LIMIT 1
Since the condition in the first where clause always evaluates to true, it picks up 1 row randomly. Which row gets picked up depends on how your DBMS stores data internally.
To know why the generated query is wrong, we'll need to see the code in your Controller's action. | unknown | |

Looking at its source, PyGithub doesn't accept any arguments for its get_contributors method, so it doesn't currently surface anon contributors. It could be forked or patched to take it.
For my needs, I'm going to write my own method that makes a request for a repo, parses the "last" relation from the Link header and calculates based on the number of results on the last page. Still writing it, so I don't have a code sample for now.

CompositeValidator.java
@Component
public class CompositeValidator implements SmartValidator {
@Autowired
private List<Validator> validators = Collections.emptyList();
@PostConstruct
public void init() {
Collections.sort(validators, AnnotationAwareOrderComparator.INSTANCE);
}
@Override

for (Validator validator : validators) {
if (validator.supports(clazz)) {
if (validator instanceof SmartValidator) {

</mvc:annotation-driven>
A: You can configure global Validator.
http://docs.spring.io/spring/docs/current/spring-framework-reference/html/validation.html#validation-mvc
If you are using Java based spring configuration with WebMvcConfigurationSupport, you can override getValidator()
/**
* Override this method to provide a custom {@link Validator}.
*/
protected Validator getValidator() {
return null;
}
You may call setValidator(Validator) on the global WebBindingInitializer. This allows you to configure a Validator instance across all @Controller classes. This can be achieved easily by using the Spring MVC namespace:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<mvc:annotation-driven validator="globalValidator"/>
</beans>
A: I have not found a build in Spring solution for this, but here is what I do.
I declare my validator beans in the spring java configuration like so:
@Bean
public Validator studentValidator(){
return new StudentValidator();
}
@Bean
public Validator carValidator(){
return new CarValidator();
}
Then I have all controllers extends a base controller like so:
public abstract class BaseController <T> {
public BaseController(List<Validator> validators) {
super();
this.validators = validators;
}
//Register all validators
@InitBinder
protected void initBinder(WebDataBinder binder) {
validators.stream().forEach(v->binder.addValidators(v));
}
}
The concrete class of this controller gets the List injected via dependency injection, like so:
@Controller
public class StudentController extends BaseController<Student>{
@Inject
public StudentController(List<Validator> validators) {
super(validators);
}
}
The base Controller uses the @InitBinder call-back method to register all Validators.
I am surprised that spring doesn't automatically register all objects in class path that implement the Validator interface. | unknown | |
d4200 | train | You can do this (and a lot of other stuff) with Object.defineProperty. Here's a basic example:

var testObj = {};
// give it a property called "false"
Object.defineProperty(testObj, 'false', {
// the "get" function decides what is returned
// when the `false` property is retrieved
get: function () {
return !value;
}
});
// return our object
return testObj;
};
var f1 = Test(false);
console.log(f1.false); // true
var f2 = Test("other");
console.log(f2.false); // false
