d2801 | train | To catch the focused input when clicking a button, you have to listen to the mousedown event as it fires before the input loses focus.
The click event is too late, the input has already lost focused by that time.
To get the currently focused (active) element, one can use document.activeElement.
So something like this :
$('#btnAdd').on('mousedown', function() {
var el = document.activeElement;
insertDataVarables(el, 'insertedText')
});
FIDDLE
A: When a cursor is positioned in a textbox save it in a global variable. The on button click insert the value to the saved element. Hope following code snippet will help you.
var selctedElm;
$(document).on('click', '#btnAdd', function () {
selctedElm && selctedElm.val('insertedText');
});
$(document).on('click', 'input[type=text]', function() {
selctedElm = $(this);
});

d2802 | train | You can't return a cfform, because tags can't be used inside of a CFScript based component. You're far better off doing something like this with a custom tag, which then references your component to get pieces to build out the form.
I would avoid (if at all possible) putting any cfform related pieces into a component, script-based or not.
If you did want to ultimately go this route, you'd need to put the cfform (and it's relevant pieces) either in another component that gets called by the script based one, or in an include that then is saved to a variable. All of the solutions related to trying to get the cfform into your CFC are going to be messy.
A: If you absolutely must do this (though I would shy away from it myself) you might want to have a look at this:

A: Check to make sure your versions of mongoDB and mongoose are compatible. You can find a compatibility chart here.
In addition to checking your MongoDB and mongoose versions, you should also check if it's actually connecting to the database by using a callback function when you connect to the server, like so:
//Connecting to database using mongoose.connect with a callback
mongoose.connect("mongodb://localhost:27017/customerapp", function(error) {
if(error) {
console.log("There was an error connecting to MongoDB.");
console.log(error);
} else {
console.log("Successfully connected to MongoDB!");
}
});
This callback may also work with mongoose.createConnection instead of mongoose.connect, but I haven't tried. If neither message prints to the console, then the app is not getting any response from the server, not even an error.
For some reason, as long as mongoDB is running at all, GET requests still seem to work even if the connection attempt hangs, but POST requests run into trouble.
Source: Mongoose never connects to mongodb | unknown | |
d2804 | train | I'd suggest you wrapping what you have used to get the update in a function then do the function call after you hit the success method after submitting the form...
In your js for example:
$(document).ready(function(){
$("#contactForm").submit(function(e){
// prevent from normal form behaviour
e.preventDefault();
// serialize the form data
var serializedData = $(this).serialize();
$.ajax({
type : 'POST',
url : "{% url 'BFS:contact_submit' %}",
data : serializedData,
success : function(response){
//reset the form after successful submit
$("#contactForm")[0].reset();
// This will then call for the get request to update the id "myText"
live_update();
},
error : function(response){
console.log(response)
}
});
});
function live_update(){
$.ajax({
url: "{% url 'BFS:get_user_info' %}",
type: 'get', // This is the default though, you don't actually need to always mention it
success: function(data) {
var number = data;
document.getElementById("myText").innerHTML = number;
},
error: function() {
alert('Got an error dude');
}
});
}
});
Also, for the success method within the live_update function... You could also use,
success: function(data) {
$("#myText").hide();
$("#myText").html(data);
$("#myText").fadeIn(1000);
},
That should give it a nice little fade in effect as it updates. :)
A: This might be the time to introduce a frontend framework to your pipeline as it will make life easier to refresh pages upon DOM state changes. I had challenges myself trying to implement similar functionality with Django alone some years back until i introduced React Js.
Here is something that could help you without learning another software altogether:
Update DOM without reloading the page in Django
However, you will notice that the marked answer there still uses Javascript i.e jQuery. So there is no denying the fact that you will need to implement javascript to achieve what you want.
Which is why i mentioned React Js.
Good luck! | unknown | |

d2807 | train | There is another way to create your custom AWS resources when localstack freshly starts up. Since you already have a bash script for your resources, you can simply volume mount your script to /docker-entrypoint-initaws.d/.
So my docker-compose file would be:
localstack:
image: localstack/localstack:latest
container_name: localstack_aws
ports:
- '4566:4566'
volumes:
- './localSetup.sh:/etc/localstack/init/ready.d/init-aws.sh'
Also, I would prefer awslocal over aws --endpoint in the bash script, as it leverages the credentials work and endpoint for you.
A: try adding hostname to the docker-compose file and editing your entrypoint file to reflect that hostname.
docker-compose.yml
version: '3'
services:
localstack:
build: .
hostname: localstack
ports:
- "8080:8080"
- "4567-4582:4567-4582"
localSetup.sh
#!/bin/bash
aws --endpoint-url=http://localstack:4572 s3 mb s3://localbucket
This was my docker-compose-dev.yaml I used for testing out an app that was using localstack. I used the command docker-compose -f docker-compose-dev.yaml up, I also used the same localSetup.sh you used.

d2812 | train | Even though you are developing locally, the assets still need to be delivered securely and pass the CORS policy to load in a-frame.
Your scene is most likely throwing some errors related to not being able to load that file securely, timing out in the process. Ideally you would want to load that gltf file via the asset management system and then reference it in an entity below. Helps avoid scene timeouts and crashing as well.
I don't know the Flask environment, but you will want a way to declare a specific asset or a local folder of assets for the app to host(again locally) to be pulled from in your a-scene. Otherwise you may want to look into other local hosting environments like the popular and free XAMPP.

You could write it like this
jeffBuysCake3('black forest')
.then(result => console.log(result))
.catch(error => console.log(error))
and the result is going to be "black forest cake",
if the promise function was like this

dimnames(result)

$b
[1] "b1" "b2"
$c
[1] "c1" "c2"
$d
[1] "d1" "d2"
A: It is really ambiguous to answer question without a reproducible example.
I answer this question, because producing an example here is interesting.
dat <- array(rnorm(16*10*15*39))
dim(dat) <- c(16,10,15,39)
dimnames(dat) <- lapply(c(16,10,15,39),
function(x) paste('a',sample(1:1000,x,rep=F),sep=''))
dat2 <- apply(dat, c(2,3,4), function(x){x/sum(x)})
identical(dimnames(dat2) ,dimnames(dat))
[1] TRUE
I get the same dimanmes for dat and dat2. So surely I miss something here.
A: I can't reproduce this behavior using a non-casted array. Could you provide a reproducable example of what your dataframe/array actually looks like?
Otherwise it is difficult to find out where the problem is.
Here is the code I used for testing this:
# example
a <- c(1,2,11,22)
b <- c(3,4,33,44)
c <- c(5,6,55,66)
d <- c(7,8,77,88)
test <- array(c(a,b,c,d), c(2,2,2,2), dimnames=list(
a=c("a1","a2"),
b=c("b1","b2"),
c=c("c1","c2"),
d=c("d1","d2") )
)
dimnames(test)
names(dimnames(test))
# apply
test2 <- apply(test, c(2,3,4), function(x){
entry <- sum(x)
})
dimnames(test2)
names(dimnames(test2))
Sorry for the comment "diguised" as an answer. I am new to SO and as it seems you need a higher rep to post comments.
Edit: Your dimnames might get lost, because for whatever reason the function your defined produces unnamed results. You can try saving x/sum(x) as an object (like I did) and then naming that object inside your function. I skipped the last part, because for me there were no missing names / dimnames | unknown | |

d2819 | train | There might be different reasons for OOM exception. One reason readily comes to my mind is is setting AUTO_READ option on the channel. The default value is true.
you can get more information about this in stack overflow posts here and here
If setting AUTO_READ option doesn't help, netty provides an option to check if any message to ChannelHandler is not released. Please set -Dio.netty.leakDetectionLevel=ADVANCED JVM option in the system properties.
A: This happens because the client is writing faster than what the server can process. This ends up filling up the client buffer (memory) and eventual crash. The solution is to adjust the client send rate based on the server. One way to achieve this is that the server periodically reports the reading rate to the client and the client adjusts the write speed based on that. | unknown | |

Grab the filename during build name and discard the file or you can try --spider for wget to just get the filename.
ARG FULLNAME
ENV FULLNAME=${FULLNAME}
Then pass the full name dynamically during build time.
For example

A: The ENV ... ... syntax is mainly for plaintext content, docker build arguments, or other environment variables. It does not support a subshell like your example.
It is also not possible to use RUN export ... and have that variable defined in downstream image layers.
The best route may be to write the name to a file in the filesystem and read from that file instead of an environment variable. Or, if an environment variable is crucial, you could set an environment variable from the contents of that file in an ENTRYPOINT script. | unknown | |

$scope.alert = window.alert;
But even it creates eval problem so correct syntax must be:
HTML
<div ng-click = "alert('Hello World!')">Click me</div>
Controller
$scope.alert = function(arg){
alert(arg);
}
A: As far as I know, ng-click works only within your $scope. So you would only be able to call functions, defined in your $scope itself. To use alert, you may try accessing the window element, just by using window.alert('Clicked').
EIDT: Thanks to Ibrahim. I forgot. You shouldn't be able to use window.alert, as far as you won't define:
$scope.alert = window.alert;
In this case, using alert('Clicked') in your ng-clicked directive should work. But at the end, this method would not solve your problem of not touching your controller.
A: You can use
onclick="alert('Clicked')"

A: As Neeraj mentioned, the accepted answer does not work. Add something like this to your controller to avoid an Illegal Invocation error:

d2831 | train | Since the modules and dependencies (AMD) are working fine on browser I assume the shims config are correct .
That's an incorrect assumption. The problem is that Node.js operates with a set of basic assumptions that are very different from how browsers work. Consider this statement:
var foo = "something";
If you execute this at the top of your scope in Node.js, you've created a variable which is local to the file Node is executing. If you really want to make it global, then you have to explicitly shove it into global.
Now, put the same statement at the top of the scope of a script you load in a browser with the script element. The same statement creates a global variable. (The variable is global whether or not var is present.)
RequireJS' shim configuration is used for scripts that expect the second behavior. They expect a) that anything they declare at the top of their scope is leaked to the global space and b) that anything that has been leaked to the global space by scripts they depend on is available in the global space. Both expectations are almost always false in Node. (It would not be impossible for a module designed for node to manipulate global but that's very rare.)
The author of RequireJS explained in this issue report that he does not see it advisable for RequireJS to try to replicate the browser behavior in Node. I agree with him. If you want to run front-end code in the back-end you should replace those modules that need shim in the browser with modules that are designed to run in Node. | unknown | |
d2832 | train | This type of formatting is tricky. You need to pay attention to the white spaces when the parse=TRUE is used. To format the text you need proceed in two steps of pasting. Let's create a simple reproducible example:
ggData <- data.frame(x=rnorm(100), y=rnorm(100) )
I recommend you to store the text AND the correlation value R outside of the ggplot function for readability of the code:
textPart1 <- "paste(italic(R), \" =\")" # check the ?annotate example for \" =\"
corVal <- round(cor(ggData$x, ggData$y, use = "complete.obs"), 3)
The trick is to paste the two variables with the sep="~" instead of the white space.
ggplot(ggData, aes(x = x, y = y) ) +
geom_point(alpha = 0.4) +
annotate("text", x = 2, y = 1.5,
label = paste(textPart1, corVal, sep="~"), size = 4 , parse=TRUE) | unknown | |
d2833 | train | You just pass the function as a value. E.g.:
let apply_twice f x = f (f x)
should do what you expect. We can try it out by testing on the command line:
utop # apply_twice ((+) 1) 100
- : int = 102
The (+) 1 term is the function that adds one to a number (you could also write it as (fun x -> 1 + x)). Also remember that a function in OCaml does not need to be evaluated with all its parameters. If you evaluate apply_twice only with the function you receive a new function that can be evaluated on a number:
utop # let add_two = apply_twice ((+) 1) ;;
val add_two : int -> int = <fun>
utop # add_two 1000;;
- : int = 1002
A: To provide a better understanding: In OCaml, functions are first-class
values. Just like int is a value, 'a -> 'a -> 'a is a value (I
suppose you are familiar with function signatures). So, how do you
implement a function that returns a function? Well, let's rephrase it:
As functions = values in OCaml, we could phrase your question in three
different forms:
[1] a function that returns a function
[2] a function that returns a value
[3] a value that returns a value
Note that those are all equivalent; I just changed terms.
[2] is probably the most intuitive one for you.
First, let's look at how OCaml evaluates functions (concrete example):
let sum x y = x + y
(val sum: int -> int -> int = <fun>)
f takes in two int's and returns an int (Intuitively speaking, a
functional value is a value, that can evaluate further if you provide
values). This is the reason you can do stuff like this:
let partial_sum = sum 2
(int -> int = <fun>)
let total_sum = partial_sum 3 (equivalent to: let total_sum y = 3 + y)
(int = 5)
partial_sum is a function, that takes in only one int and returns
another int. So we already provided one argument of the function,
now one is still missing, so it's still a functional value. If that is
still not clear, look into it more. (Hint: f x = x is equivalent to
f = fun x -> x) Let's come back to your question. The simplest
function, that returns a function is the function itself:
let f x = x
(val f:'a -> 'a = <fun>)
f
('a -> 'a = <fun>)
let f x = x Calling f without arguments returns f itself. Say you
wanted to concatenate two functions, so f o g, or f(g(x)):
let g x = (* do something *)
(val g: 'a -> 'b)
let f x = (* do something *)
(val f: 'a -> 'b)
let f_g f g x = f (g x)
(val f_g: ('a -> 'b) -> ('c -> 'a) -> 'c -> 'b = <fun>)
('a -> 'b): that's f, ('c -> 'a): that's g, c: that's x.
Exercise: Think about why the particular signatures have to be like that. Because let f_g f g x = f (g x) is equivalent to let f_g = fun f -> fun g -> fun x -> f (g x), and we do not provide
the argument x, we have created a function concatenation. Play around
with providing partial arguments, look at the signature, and there
will be nothing magical about functions returning functions; or:
functions returning values. | unknown | |

d2835 | train | I have only made some improvements in regards to the views, I haven't looked at the models.
*
*First you should change from the generic generic.View to
generic.CreateView since you are creating stuff.
*When deriving from generic.CreateView you can move out the
template_name and context from the functions and put them in the
class instead, since they stay the same for both the GET and
POST operations.
*Then you don't need to user the render functions, you can just call
the super that should handle the render for you.
*And lastly you can create a mixin that handles the logic in the user
creation, as it's largely the same.
With the suggestions above it should look something like this. You might need to tweak it, I haven't been able to test it fully.

FB.Canvas.setAutoGrow (Working perfect!)
Note: this method is only enabled when Canvas Height is set to "Settable (Default: 800px)" in the Developer App.
Starts or stops a timer which will grow your iframe to fit the content every few milliseconds. Default timeout is 100ms.
Examples
This function is useful if you know your content will change size, but you don't know when. There will be a slight delay, so if you know when your content changes size, you should call setSize yourself (and save your user's CPU cycles).
window.fbAsyncInit = function() {
FB.Canvas.setAutoGrow();
}
If you ever need to stop the timer, just pass false.
FB.Canvas.setAutoGrow(false);
If you want the timer to run at a different interval, you can do that too.
FB.Canvas.setAutoGrow(91); // Paul's favourite number
Note: If there is only 1 parameter and it is a number, it is assumed to be the interval.
A: You cant do that with PHP SDk (i think)

d2841 | train | For starters, the difference between static and instance variables is that, only ONE static variable exists for all the instances of the class, whereas an instance variable exists for EVERY instance of the class.
Now, when you are talking about methods, in most cases you need to make a method static when you are trying to call it from another static method (such as main).
In general this practice is wrong for OOP, and chances are you should rethink the way the program is structured.
If you could provide more details about the code you use to call these methods, I would be able to help you with more details on how to fix this.
EDIT:
In light of the new info you provided:
1) I believe that bmrMain,BMRMain and Calculations can all be merged into one class. The constructor of the new class should be adjusted to read input (as well as getters and setters for each variable for added flexibility - optional)
2) Regarding the calculation of the bmr part, there are many ways to tackle this, so I will go ahead and suggest the one that is best in my opinion.
Add a Button with a text "Click to calculate" or something similar, and implement an ActionListener. The action Listener will in turn call (whenever the button is clicked) the method that calculates everything, and finally it will change the text on the JLabel.
sample code for the action Listener:
JButton button = new JButton("Text Button");
button.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
//Call the methods for the calculation
// bmr and tdee are temporary variables to store the results from the methods
//handle them properly, or remove them if not needed (I just wrote a sample)
int bmr = calcBMR(...); //pass the correct variables as arguments here
int tdee;
if(userHasPickedTDEE) { tdee = calcTDEE(...); } //and here
label.setText(....);
}
});
These 2 steps will take care of your "static" problem.
I recommend that you do some research on event-driven programming
And here is some extra and more in-depth reading on Action Listeners
If you need further help, or clarifications let me know :)
EDIT2:
In general, yes it is a good practice to separate classes in order to keep the code manageable. But in this case I think it is a bit superfluous to create a new class just for 2 methods.
Nevertheless if you would like to keep the current structure, the way to fix the "static" is:
1) remove static from the 2 calculation methods.
2)line 332 should be
Calculations c = new Calculations();
bmrValue = c.calcBMR(userAge, userGender, userHeight, userWeight);
FINAL_EDIT:
Well, these questions can easily be transferred to a thread of their own. But here is a useful link from a quick google search I just did, that will help demistify the static keyword:
Static keyword in Java
A: My thumb rule for using static variables goes somewhat like this:
*
*Do not use static
*When it is needed to use static refer to (1)
For most cases, the above thumb rule works. But then, we have standard idioms popularized by JDK, apache-commons libraries. Looking into them you find that:
*
*It is OK to have utility classes that contain all static methods.
*It is OK to create constants using static fields in classes. Though, for this using Enum might be a better choice.
*It is OK to one off utility functions that work on the same class into the class.
As for the restructuring the code goes, you should be looking at who owns the data. In this case, both the methods from Calculations class looks to be using data from the other class. Move the methods into the other class.
The only reason for existence of Calculations class should be that if you are using the methods from multiple other classes which are not related. If they are related, you try to model their relationship and see where these methods go.
A: I use static whenever my class is just used to call those methods (i.e. my main method calls the static methods to set variables in the main class, etc). I believe that is the "utility" class that KDM mentioned. A small example of when I use static or utility classes:
class Utility {
public static int add(int a, int b) {
// You would, of course, put something besides simple addition here
return a + b;
}
}
class Main {
public static void main(String[] args) {
int a = 2, b = 3;
int sum = Utility.add(a, b);
System.out.println(sum);
}
}
On the other hand, if you have a class that is closer to an actual object, with properties of its own, stay away from static. If you use static, then each instance of the class which you want to be separate objects will end up with same values.
Based on the name and functionality of your class, it appears you have a utility class. Static should be fine, but it may not be necessary. Hypothetically, though, if you wanted to use this class with multiple "people" class instances for which to calculate the BMR (where each instance is unique), then I would put calcBMR() in a person class and make it non-static so that each person has their own calcBMR().
Edit: Maybe this will help too:
Instance -> Instantiate: new Calculations().instanceMethod();
Static -> Class itself, the class's "state": Calculations.staticMethod();
A: If you think in terms of, do I want instance methods or static methods, you're going to be lost. Java isn't method-oriented, it's object-oriented. So for your functionality, decide whether you want an object or a pure function (where pure function means no dependencies and no side-effects, it's strictly a function that given this returns that).
It might be good to model this as an object, since you have information describing some aspect of the User and it may make sense to keep it together:
public class User {
private int age;
private String gender; // todo: use an Enum
private double height;
private double weight;
private String activityLevel; // todo: use an Enum
public User(int age, String gender, double height, double weight,
String activityLevel) {
this.age = age;
this.gender = gender;
this.height = height;
this.weight = weight;
this.activityLevel = activityLevel;
}
public double calculateBmr() {
int offset = gender.equals("M") ? 5 : -161;
return (int) (Math.round((10 * weight)
+ (6.25 * height) - (5 * age) + offset));
}
}
etc. This way we don't have to preface the variables with "user", they're all placed together in one object. Objects are an organizational scheme for collecting related information, the instance methods are functions that use the object's information.
The alternative route is to create a utility class:
public final class UserCalcUtil {
private UserCalcUtil() {} // no point instantiating this
public static int calculateBmr(String gender, double height,
double weight, int age) {
int offset = gender.equals("M") ? 5 : -161;
return (int) (Math.round((10 * weight)
+ (6.25 * height) - (5 * age) + offset));
}
}
Here you're keeping track of the user data separately, and passing it in to the static method when you want to calculate something. The utility class is a dumping ground for separate static methods (which you can think of as functions).
Whether you want to use objects or utility classes depends on how you want to organize your data and do calculations on it. Packing the data for a User together with the methods that act on that data may be more convenient if you always do the calculations on the individual objects, or moving the calculations into a utility class might make sense if there are multiple unrelated classes that you want to do calculations for. Since Java has more support for object-oriented constructs it often makes sense to take the object approach.
And you can use static methods, but avoid static variables for anything but constants (public static final, with a type that's immutable). | unknown | |

d2844 | train | When you do Debug->Attach to Process you'll see that VS displays a list of processes and along with them it displays the types of code that you can debug which are running in those processes. To get this information VS queries the various installed debug engines. So when we get queried we go and inspect a bunch of processes to see what's going on. If it's a 32 bit process life is easy - we can use various APIs to enumerate the modules and try and figure out if there's a Python interpreter in the process. If it's a 64-bit process life is a little tougher because we're running inside of VS and it's a 32-bit process. We can't use the APIs from a 32-bit to a 64-bit process so instead we spawn a helper process to do the work.
It sounds like this helper process is somehow becoming a zombie on your system. It'd be great if you could attach VS to it and send any stack traces back in a bug. But we should also provide some defense in depth and timeout if the helper process isn't responding.
Finally killing it should generally be safe, it's not doing anything stateful, and we'll start a new one when we need it.
If you never use Debug->Attach to Process for Python debugging there's probably a trivial file update to our .pkgdef file which I could track down and post which would make this problem go away entirely. | unknown | |

d2846 | train | I can't figure out what you think is wrong with your approach, but here is the code I was using to test with:
class Program
{
static void Main(string[] args)
{
RAMDirectory dir = new RAMDirectory();
IndexWriter writer = new IndexWriter(dir, new StandardAnalyzer());
AddDocument(writer, "John Doe", "NY");
AddDocument(writer, "John Foo", "New Jersey");
AddDocument(writer, "XYZ", "NY");
writer.Commit();
BooleanQuery query = new BooleanQuery();
query.Add(new TermQuery(new Term("Name", "john")), BooleanClause.Occur.SHOULD);
query.Add(new TermQuery(new Term("Location", "NY")), BooleanClause.Occur.SHOULD);
IndexReader reader = writer.GetReader();
IndexSearcher searcher = new IndexSearcher(reader);
var hits = searcher.Search(query, null, 10);
for (int i = 0; i < hits.totalHits; i++)
{
Document doc = searcher.Doc(hits.scoreDocs[i].doc);
var explain = searcher.Explain(query, hits.scoreDocs[i].doc);
Console.WriteLine("{0} - {1} - {2}", hits.scoreDocs[i].score, doc.ToString(), explain.ToString());
}
}
private static void AddDocument(IndexWriter writer, string name, string address)
{
Document objDocument = new Document();
Field objName = new Field("Name", name, Field.Store.YES, Field.Index.ANALYZED);
Field objLocation = new Field("Location", address, Field.Store.YES, Field.Index.NOT_ANALYZED);
objLocation.SetBoost(2f);
objDocument.Add(objName);
objDocument.Add(objLocation);
writer.AddDocument(objDocument);
}
}
This code does return the results in the order you wish. In fact it returns them in that order for this set if you exclude the boost. I'm not an expert on Lucene scoring, but I believe this is because you are matching "NY" exactly for "XYZ, NY", and the "John" query is a partial match. You can read the details printed out via the Explain class.

d2849 | train | My recommendation would be to use an MSI based installer instead of trying to roll your own using Windows Forms. Look into using the Windows Installer XML (WiX) toolset which is a popular free open source toolset for creating installers.
Using MSI has many advantages, in particular it makes it fairly difficult to mix installer logic and UI (kind of like falling into the pit of success) and so making an unattended installer suitable for running on a remote machine is a piece of cake.
If you are already committed to your current installation method then you need to work on separating your UI and logic to the point where you can run an installation without showing any UI - its difficult to give any specific advice on how to do this without a more concrete example. | unknown | |

d2861 | train | To add to other answers, consider that any function exposed through a shared object or DLL (depending on platform) can be overridden at run-time. Linux provides the LD_PRELOAD environment variable, which can specify a shared object to load after all others, which can be used to override arbitrary function definitions. It's actually about the best way to provide a "mock object" for unit-testing purposes, since it is not really invasive. However, unlike other forms of monkey-patching, be aware that a change like this is global. You can't specify one particular call to be different, without impacting other calls.
A: Considering the "guerilla third-party library use" aspect of monkey-patching, C++ offers a number of facilities:
*
*const_cast lets you work around zealous const declarations.
*#define private public prior to header inclusion lets you access private members.
*subclassing and use Parent::protected_field lets you access protected members.
*you can redefine a number of things at link time.
If the third party content you're working around is provided already compiled, though, most of the things feasible in dynamic languages isn't as easy, and often isn't possible at all.
A: I suppose it depends what you want to do. If you've already linked your program, you're gonna have a hard time replacing anything (short of actually changing the instructions in memory, which might be a stretch as well). However, before this happens, there are options. If you have a dynamically linked program, you can alter the way the linker operates (e.g. LD_LIBRARY_PATH environment variable) and have it link something else than the intended library.
Have a look at valgrind for example, which replaces (among alot of other magic stuff it's dealing with) the standard memory allocation mechanisms.
A: Not portably so, and due to the dangers for larger projects you better have good reason.
The Preprocessor is probably the best candidate, due to it's ignorance of the language itself. It can be used to rename attributes, methods and other symbol names - but the replacement is global at least for a single #include or sequence of code.
I've used that before to beat "library diamonds" into submission - Library A and B both importing an OS library S, but in different ways so that some symbols of S would be identically named but different. (namespaces were out of the question, for they'd have much more far-reaching consequences).
Similary, you can replace symbol names with compatible-but-superior classes.
e.g. in VC, #import generates an import library that uses _bstr_t as type adapter. In one project I've successfully replaced these _bstr_t uses with a compatible-enough class that interoperated better with other code, just be #define'ing _bstr_t as my replacement class for the #import.
Patching the Virtual Method Table - either replacing the entire VMT or individual methods - is somethign else I've come across. It requires good understanding of how your compiler implements VMTs. I wouldn't do that in a real life project, because it depends on compiler internals, and you don't get any warning when thigns have changed. It's a fun exercise to learn about the implementation details of C++, though. One application would be switching at runtime from an initializer/loader stub to a full - or even data-dependent - implementation.
Generating code on the fly is common in certain scenarios, such as forwarding/filtering COM Interface calls or mapping OS Window Handles to library objects. I'm not sure if this is still "monkey-patching", as it isn't really toying with the language itself.
A: As monkey patching refers to dynamically changing code, I can't imagine how this could be implemented in C++... | unknown | |
d2862 | train | EclEmma - is Eclipse plugin based on Java Code Coverage Library called JaCoCo that performs analysis of Java bytecode. Description of coverage counters provided by JaCoCo can be found in its documentation. As you can see in it - JaCoCo and hence EclEmma provide
*
*instructions coverage
*branch coverage
*line coverage
*and cyclomatic complexity
Don't know what you call node coverage, and I'm guessing that what you call edge coverage - is branch coverage.
Regarding condition coverage - Wikipedia says
if (a && b) { /* ... */ }
condition coverage can be satisfied by two tests a=true, b=false, a=false, b=true
what seems a bit weird in case of Java where && is a short-circuit operator - second test can't trigger retrieval of value of "b".
Regarding path coverage - JaCoCo does not provide it, what can be demonstrated using following example:
void fun(boolean a, boolean b) {
if (a) { /* ... */ }
if (b) { /* ... */ }
}
Not counting exception there are 4 paths thru this method. And so for full path coverage 4 tests will be required - a = true, b = true, a = true, b = false, a = false, b = true and a = false, b = false. However JaCoCo and EclEmma would report 100% coverage after just 2 tests - a = true, b = true and a = false, b = false. | unknown | |

SELECT [id]

,LAG([current load count]) OVER (ORDER BY [timestamp] ASC, [id]) AS [previous load count]

The LAG function can be used to access data from a previous row in the same result set without the use of a self-join.
It is available after SQL Server 2012.
In the example I added ordering by id, too - in case you have records with same date, but you can remove it if you like.
A: If you need exactly one day before, consider a join:
select t.*, tprev.load_count as prev_load_count
from t left join
t tprev
on tprev.timestamp = dateadd(day, -1, t.timestamp);
(Note: If the timestamp has a time component, you will need to convert to a date.)
lag() gives you the data from the previous row. If you know you have no gaps, then these are equivalent. However, if there are gaps, then this returns NULL on the days after the gap. That appears to be what you are asking for.
You can incorporate either this or lag() into an update:

d2877 | train | I dont claim to be an expert on REST but here is what I would probably do.
In your domain model, if a resource cannot exist without a user then its perfectly OK to model URL calls such as
GET /user/{userId}/resource //Gets all resources of a user
On the other hand if resources can exist without users then this link on stackoverflow gives a nice way of modelling such calls.
RESTful Many-to-Many possible?
Another thing which we did for one of our projects was that, we had the linking table (UserResource table(id,userId,resourceId) ,and we had a unique ID for that and had something like
GET /userResource/{userResourceId}
GET /userResource //Retrieve all the resources user has access to
If security is your concern , there are links on StackOverflow on how to integrate Security with Rest calls. Ideally such logic should be handled on the serverside. You typically do not want to put that logic into the REST url.
For example if you get a call for
GET /resource //Get all resources
Depending on who the user is, you return only that subset of resources he has access to.
Bottom Line : Dont build your resources around permissions.
Again, I am not an expert. Just my humble views. :-) | unknown | |
d2878 | train | You can use awk or vim macro.
awk is really great for such text manipulation
awk '{count++; print count " " $2 " "$3;}' data.stat > /tmp/data.stat && mv /tmp/data.stat data.stat
A: in Vim:
:let i=1 | g/^[^/\t]*\t/s//\= i. "\t"/ | let i=i+1
Reference
Update
For splitting the first two columns and saving into another file,
I recommend using awk as in Tomáš Šíma's answer, specifically:
awk '{print $1 "\t" $2;}' data.stat > newfilename.txt
If you want to to do everything in Vim:
*
*Copy the current file to a new one
:w newfilename.txt
*
*Open the newly copied file:
:o newfilename.txt
*
*Split the first two columns of the rest of the line:
:%s/^\([^\t]*\)\t\([^\t]*\).*$/\1\t\2/g
*
*Save your edits of course
:w newfilename.txt | unknown | |
d2879 | train | If you aim to manipulate your actions before handle them you can use beforeAction in your controller/component, with something like this:
protected function beforeAction($action) {
#check a preg_match on a url sanitization pattern, like "[^-A-Za-z0-9+&@#/%?=~_|!:,.;\(\)]", for instance
return parent::beforeAction($action);
}
A: This articles shows how you can make your application secure with SQL Injections, XSS Attacks and CSRF.
Hope it helps you.
A: Firstly, you can use regular expressions to validate your inputs, you can generalize your inputs in some regular expresions, something like this:
$num = $_GET["index"];
if (preg_match("^\d{2}$", $num)) {
//allowed
} else {
//not allowed
}
Also you can create a white list or black list, if your inputs can be grouped into what is allowed in your application, use a white list, otherwise use a black list. This lists can be sotored in your database or files, something you can easily upgrade without affecting your application. You just have to compare your inputs with that list before proccesing your inputs.
My last recommendation is encoding, you should encode your inputs and outputs, because your data from database can contain malicious code, maybe someone put it by mistake or mischief, always think in all possibilities. For this case, I remember the functions htmlspecialchars and utf8_encode, I think you should the first function, also you can analyze your inputs and build your own encoding function.
I share the following links:
*
*http://php.net/manual/es/function.preg-match.php
*http://php.net/manual/es/function.utf8-encode.php
*http://php.net/manual/es/function.htmlspecialchars.php
*https://www.owasp.org/index.php/XSS_%28Cross_Site_Scripting%29_Prevention_Cheat_Sheet
I hope this information helps you.
Good Luck.
A: for all actions in same just add a event handle to onBeginRequest:
$this->attachEventHandler('onBeginRequest', [$this, 'purifyParams']);
public function purifyParams($event)
{
$userAgent = $this->getRequest()->getUserAgent();
$isIE = preg_match('/(msie)[ \/]([\w.]+)/i', $userAgent, $version);

d2882 | train | Loosely speaking, if the purpose of your method is to retrieve data from the server use GET. e.g. getting information to display on the client.
If you are sending data to the server use POST. e.g. sending information to the server to be saved on a database somewhere.
There is a limit to the size of data you can send to the server with a GET request.
A: The server side GET or POST is used to specify what the server expects to receive in order to accept the request. The client side GET or POST is used to specify what will be sent to the server. These two must match. You cannot send a GET request when server expects a POST and vice-versa.
When you are building a server application, it is important to know the appropriate request type to use, which by itself is a whole big different topic which you should research if it is you the one that builds the server side part. | unknown | |
d2883 | train | No, you send the data however you like but keep in mind how you send it will affect how you can retrieve it.
Also you aren't sending JSON in your request as .serialize() does not return JSON it returns a text string in standard URL-encoded notation.
A: No, you don't need to send it as JSON. You can send it in any other format, but your receiver will need to know how to interpret it. Usually people use JSON or XML since your receiver can easily parse these types of data.
You'll need to set the content-type, then you can tell the receiver how to process this content-type. | unknown | |
d2884 | train | Git's merge operation considers exactly three points when doing a merge: the two heads (usually branches) that you want to merge, and the merge base, which is usually the point at which one was forked from the other.
When a merge occurs, Git considers the changes computed between each head and the merge base. It then produces a result exactly like the merge base, but with both sets of changes added. In other words:
*
*If you made a change on one side and not the other, Git will include the change. A change in this case includes the addition, removal, or modification of a file or part of it.
*If you made a change to the same location on both sides, Git will produce a conflict.
*If you made no changes to a file or part of it, Git will include those portions unchanged.
So in your case, you've only added and modified things, so the merge result will include only additions and modifications, not removals. It is possible you'll see a conflict, though. | unknown | |

d2888 | train | This isn't really a problem - the different renderers are rendering the report appropriately for their output. The web viewer is optimised for screen-based reading and generally allows more content per page than the PDF viewer does as the PDF viewer is constrained by the paper size that it formats to. Thus you get more pages when rendering for PDF than web; however, the content of the report is exactly the same.
The best illustration of this is the Excel renderer - the Excel renderer renders the entire report onto a single worksheet in most cases (for reports with grouping and page breaks set on the group footer it will render each group on its own worksheet). You wouldn't want the Excel renderer to artificially create worksheets to try to paginate your report. It does the appropriate thing which is to include all the data in one big worksheet even though that may be logically thought of as one big "page".
The web renderer page length is determined by the InteractiveHeight attribute of the report (in the InteractiveSize property in the Properties pane for the report) but the interactive height is an approximation rather than a fixed page break setting and your page breaks may still not conform to the PDF version even though the InteractiveHeight is set to the same length as your target page length. | unknown | |

d2895 | train | By default Express Checkout is for PayPal accountholder payments; originally you would pair this with some other product for credit card payments (such as collecting the card information on your site and calling PayPal DirectPay or some other card processing partner).
PayPal also has several somewhat-similar products that collect the card information on their site (so you don't have to) and do that as well as accountholder payments; these vary in whether they end up giving you access to the credit card information (more flexible, but means you have to safely handle the card information and meet industry regulations, including vetting) or you do not ever see the card, just the money (simpler). This is often called some form of "guest checkout."
And eventually PayPal did add a guest checkout option to Express Checkout called "Account Optional." So you can use Express Checkout and get a guest checkout experience. See this link:
PayPal: express checkout pay without account
So in short you can get this from EC if you configure things for it, although some other PayPal products might be a better fit depending upon your particular requirements. | unknown | |

mysql> create table `index` (url varchar(50));

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'index(url) values ('http://www.google.com')' at line 1
mysql> insert into `index`(url) values ('http://www.google.com');
Query OK, 1 row affected (0.00 sec)
index is a keyword in MySQL. Your life will be easier if you do not use it as a table name.
However, if you really want to, you can use it, but then you have to quote it:
cursor.execute("""INSERT INTO `index`(url) VALUES(%s)""", (url,))
PS: No need to call
url = mdb.escape_string("http://www.google.com")
MySQLdb will do that automatically for you when you call
cursor.execute("""INSERT INTO index(url) VALUES(%s)""", (url,))
In fact, since cursor.execute calls mdb.escape_string for you, doing it yourself could cause undesired values to be inserted into the database depending on the value of url:
In [105]: MySQLdb.escape_string("That's all folks")
Out[105]: "That\\'s all folks"
In [106]: MySQLdb.escape_string(MySQLdb.escape_string("That's all folks"))

d2898 | train | I think the following regexp fit the job. Howevever you don't have to have nested curly bracket (nested curly bracket can't be parsed using regular expression as far as I know)
>>> s= "{abc, xyz}, 123, {def, lmn, ijk}, {uvw}, opq"
>>> re.findall(r",?\s*(\{.*?\}|[^,]+)",s)
['{abc, xyz}', '123', '{def, lmn, ijk}', '{uvw}', 'opq']
A: given = "{abc,{a:b}, xyz} , 123 , {def, lmn, ijk}, {uvw}, opq"
#expected = ["{abc, xyz}", "123", "{def, lmn, ijk}", "{uvw}", "opq"]
tmp_l = given.split(',')
tmp_l = [i.strip() for i in tmp_l]
result_l = []
element = ''
count = 0
for i in tmp_l:
if i[0] == '{':
count += 1
if i[-1] == '}':
count -= 1
element = element + i + ','
if count == 0:
element = element[0:-1]
result_l.append(element)
element = ''
print str(result_l)
this one can handle nested curly bracket, although it seems not so elegant..
A: Does the following not provide you with what you are looking for?
import re
given = "{abc, xyz}, 123, {def, lmn, ijk}, {uvw}, opq"
expected = re.findall(r'(\w+)', given)
I ran that in Terminal and got:
>>> import re
>>> given = "{abc, xyz}, 123, {def, lmn, ijk}, {uvw}, opq"
>>> expected = re.findall(r'(\w+)', given)
>>> expected
['abc', 'xyz', '123', 'def', 'lmn', 'ijk', 'uvw', 'opq']
A: You can use the below regex to do that. Rest is same as the similar link you provided.
given = "{abc, xyz}, 123, {def, lmn, ijk}, {uvw}, opq"
regex = r",?\s*(\{.*?\}|[^,]+)"
print re.findall(regex,given)
OP: ['{abc, xyz}', '123', '{def, lmn, ijk}', '{uvw}', 'opq']
Just import the re module. and do the same as the link says.
It will match anything inside the curly braces { } and any string. | unknown | |
