A: I managed to do it like this, but it's not the case.... I need to do that exercise using operations on collections, sorry for answering my question, but I wanted to my solution to be visible better.

d13503 | train | In your code sample you did not call the setValues() function. That's why you could not control the input. Here are some modifications to your code:
const inputName = (index, event) => {

tempValues[index].name = event.target.value;
setValues(tempValues);
};
I hope this code will work now. I have tested it in your codesandbox example also.

d13504 | train | I have solved the problem.
I looked up the log file and in my case the table is an external table referring to a directory located on hdfs. This directory contains more than 300000 files. So while reading the files it was throwing an out of memory exception and may be for this reason it was getting an empty string and throwing 'Can not create a Path from an empty string' exception.
I tried with a smaller subset of files and it worked.
Bottomline, one possible cause for this exception is running out of memory.
A: I my case, there is a hive property which is set
set hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat; in .hiverc file which is throwing the exception.
Diagnostic Messages for this Task:

After changing it to below, it worked
set hive.input.format=org.apache.hadoop.hive.ql.io.CombineHiveInputFormat;
A: I encountered the same error. My hive.log file showed the cause - see the first line in the snippet below where one of the jar file URIs contains file:// without any path:

d13505 | train | Scipy's stats.entropy in its default sense invites inputs as 1D arrays giving us a scalar, which is being done in the listed question. Internally this function also allows broadcasting, which we can abuse in here for a vectorized solution.
From the docs -
scipy.stats.entropy(pk, qk=None, base=None)
If only probabilities pk
are given, the entropy is calculated as S = -sum(pk * log(pk),
axis=0).
If qk is not None, then compute the Kullback-Leibler divergence S =
sum(pk * log(pk / qk), axis=0).
In our case, we are doing these entropy calculations for each row against all rows, performing sum reductions to have a scalar at each iteration with those two nested loops. Thus, the output array would be of shape (M,M), where M is the number of rows in input array.
Now, the catch here is that stats.entropy() would sum along axis=0, so we will feed it two versions of distributions, both of whom would have the rowth-dimension brought to axis=0 for reduction along it and the other two axes interleaved - (M,1) & (1,M) to give us a (M,M) shaped output array using broadcasting.
Thus, a vectorized and much more efficient way to solve our case would be -
from scipy import stats
kld = stats.entropy(distributions.T[:,:,None], distributions.T[:,None,:])
Runtime tests and verify -
In [15]: def entropy_loopy(distrib):
...: n = distrib.shape[0] #n is the number of data points
...: kld = np.zeros((n, n))
...: for i in range(0, n):
...: for j in range(0, n):
...: if(i != j):

d13507 | train | To use TestBed you have to alter your karma.conf.js to:
// list of files / patterns to load in the browser
files: [
'src/tests/setup.ts',
'src/tests/**/*.spec.ts'
],
The file src/tests/setup.ts should look like this for jasmine:
import "nativescript-angular/zone-js/testing.jasmine";
import {nsTestBedInit} from "nativescript-angular/testing";
nsTestBedInit();
or if using mocha:
import "nativescript-angular/zone-js/testing.mocha";
import {nsTestBedInit} from "nativescript-angular/testing";
nsTestBedInit();
You'll find a sample here: https://github.com/hypery2k/tns_testbed_sample
A: I was facing the same issue like you. I finally found a way to make Unit Test in Nativescript-Angular works.
To fix my issue I add beforeAll(() => nsTestBedInit()); and afterAll(() => { });
Also change from TestBed to nsTestBed...
I just follow the idea on https://github.com/NativeScript/nativescript-angular/blob/master/tests/app/tests/detached-loader-tests.ts
Also add into tsconfig.tns.json file this line:
"include": ["src/tests/*.spec.ts"],
My issue now is split all test into multiple file. Like appComponent in a test file
and homeCompenent in a second test file. When the app grow the unit test also grow, we need organize our code.
Here my code (file name: src/tests/test.spec.ts):
import "reflect-metadata";
import { AppComponent } from "../app/app.component";
import { nsTestBedBeforeEach, nsTestBedAfterEach, nsTestBedRender, nsTestBedInit } from "nativescript-angular/testing";
import { HomeComponent } from "@src/app/home/home.component";
describe("AppComponent", () => {
beforeAll(() => nsTestBedInit());
afterAll(() => { });
beforeEach(nsTestBedBeforeEach([AppComponent, HomeComponent]));
afterEach(nsTestBedAfterEach());
it("should be: app works!", () => {
return nsTestBedRender(AppComponent).then((fixture) => {
fixture.detectChanges();
const app = fixture.componentInstance;
expect(app.title).toBe("app works!");
});
});
describe("HomeComponent", () => {
it("should contain: Home works!", () => {
return nsTestBedRender(HomeComponent).then((fixture) => {
fixture.detectChanges();
const app = fixture.componentInstance;
expect(app.title).toBe("Home works!");
});
});

ssh "root@$ip" < /dev/null
That may also apply with -tt since somehow it's independent. Just try.

d13511 | train | ToolTip.Show Method (String, IWin32Window)
The second argument is the control for which the tool tip is to be shown.
toolTip1.Show("Test 123", button1, Int32.MaxValue);
Visual Studio tracks the word underneath the mouse and displays tooltips/intellisense accordingly. One way for you to do the same could be to:
*
*Track the mouse movements
*Get the text under mouse
*Show tooltip.
A: The ToolTip.Show method also has other more appropriate overloads, like this one.
You can pass the edit control (that is, your text box) that you want to be associated with the tooltip as the IWin32Window parameter.
Then, you can specify the current coordinates of the mouse cursor as the X and Y arguments:
*
*If you're trying to show this tooltip in one of the mouse event handlers (like MouseMove), the current coordinates of the mouse cursor are passed in as part of the MouseEventArgs—just use the e.X and e.Y properties.
*Otherwise, you'll need to use the Control.MousePosition property to get its current location, which will return a Point representing its current location relative to screen coordinates. Another one of the overloads to the ToolTip.Show method accepts a Point parameter that you can use here instead of separate X and Y coordinates | unknown | |

d13513 | train | That particular formulation is not supported in .gitignore:
An optional prefix "!" which negates the pattern; any matching file
excluded by a previous pattern will become included again. It is not
possible to re-include a file if a parent directory of that file is
excluded. Git doesn’t list excluded directories for performance
reasons, so any patterns on contained files have no effect, no matter
where they are defined. Put a backslash ("\") in front of the first
"!" for patterns that begin with a literal "!", for example,
"\!important!.txt".
Instead, you can do:
foo/*
!foo/baz

?? .gitignore
?? foo/
:: git add foo
:: git status -sb
## Initial commit on master
A foo/baz
?? .gitignore

To see what things look like if baz was not in foo, we can reset and then remove baz:
:: git reset
:: rm foo/baz
:: git status -sb
## Initial commit on master
?? .gitignore

d13514 | train | "Otherwise, if the member or constructor is declared private, then access is permitted if and only if it occurs within the body of the top level class (§7.6) that encloses the declaration of the member or constructor." JLS 6.6.1 In this case, TestOutter is the top-level class, so all private fields inside it are visible.
Basically, the purpose of declaring a member private is to help ensure correctness by keeping other classes (subclasses or otherwise) from meddling with it. Since a top-level class is the Java compilation unit, the spec assumes that access within the same file has been appropriately managed.
A: This is because the inner class, as a member of the outer class, has access to all the private variables of its outer class. And since the other inner class is also a member of the outer class, all of its private variables are accessible as well.
Edit: Think of it like you have a couple of couch cushion forts(inner classes) in a house(outer class), one yours the other your siblings. Your forts are both in the house so you have access to all the things in your house. And mom(Java) is being totally lame and saying you have to share with your sibling because everything in the house is everyone elses and if you want your own fort you are going to have to buy it with your own money(make another class?). | unknown | |
d13515 | train | Function names, like arrays, decay into pointers when used. That means you can just:
printf("%p", myFunction);
On most systems, anyway. To be strictly standard-compliant, check out How to format a function pointer?
A: There are a few ways to get at this. The easiest is probably to use a debugger.
Using GDB
With gdb you can connect to a running program. Say for example I want to connect to a running vim process. First I need to know it's PID number:
$ pidof vim
15425
I can now connect to the process using gdb:
$ gdb `which vim` 15425
At the prompt, I can now enquire about different symbols:
$ info symbol fprintf
fprintf in section .text of /lib/x86_64-linux-gnu/libc.so.6
$ info address fprintf
Symbol "fprintf" is at 0x7fc9b44314a0 in a file compiled without debugging.
Using /proc
Another way to get a dump of memory locations of libraries from /proc.
Again, you need the PID (see above) and you can dump out the libraries and their locations in the virtual memory of a process.
$ cat /proc/15425/maps
7fc9a9427000-7fc9a9432000 r-xp 00000000 fd:02 539295973 /lib/x86_64-linux-gnu/libnss_files-2.19.so

Code above was based on AX 2012 code. Stupid solution to a stupid problem.
It goes almost without saying that you should report the problem to Microsoft.
A: @Jan B. Kjeldsen's answer describes how the specific case can be solved without involving Microsoft.
Since overlayering is no longer possible, the solution involves copying a fair bit of standard code. This brings its own risks, because future changes by Microsoft for that code are not reflected in the copied code.
Though it cannot always be avoided, other options should be evaluated first:
*
*As @Jan B. Kjeldsen mentioned, errors in the standard code should be reported to Microsoft (see Get support for Finance and Operations apps or Lifecycle Services (LCS)). This enables them to fix the error.
*
*Pro: No further work needed.
*Con: Microsoft may decline the fix or take a long time to implement it.
*If unlike in this specific case the issue is not a downright error, but a lack of extension options, an extensibility request can be created with Microsoft. They will then add an extension option.
*
*Pro: No further work needed.
*Con: Microsoft may decline the extensibility request or take a long time to implement it.
*For both errors as well as missing extension options, Microsoft also offers the Community Driven Engineering program (CDE). This enables you to develop changes in the standard code directly via a special Microsoft hosted repository where the standard code is not locked for changes.
*
*Pro: Most flexible and fastest of all options involving Microsoft.
*Con: You have to do the work yourself. Microsoft may decline the change. It can still take some time before the change is available in a GA version.
You can also consider a hybrid approach: For a quick solution, copy standard code and customize it as required. But also report an error, create an extensibility request or fix it yourself in the CDE program. When the change is available in standard code, you can then remove the copied code again. | unknown | |

d13521 | train | A better solution would be to parse out your document libraries so they aren't exceeding the list view threshold. Assuming you're running 2013 since you tagged it in your post, you could have the workflow do a REST API call to the destination library and check the item count.

If Variable: count is less than 5000

d13522 | train | In C89 (the original "ANSI C"), values used in initialiser lists must be "constant expressions". One type of constant expression is an address constant, and a pointer to an object with static storage duration is an address constant.
However, a pointer to an object with automatic storage duration is not an address constant (its value is not known at compile-time), so it cannot be used in an initialiser list.
You only need to make the array a have static storage duration - the following will work too:
main()
{
static int a[]={1,2,3};
int *p[]={a,a+1,a+2};
......
}
C99 has relaxed this restriction for initialisers for objects that have automatic storage duration (which is why gcc is OK with it).
Why is it so? Initialiser lists are typically used for initialising potentially large objects, like arrays or structures. Objects with automatic storage duration must be initialised anew each time the function is entered, and the C89 rules allow compiler writes to do this initialisation by emitting a simple memcpy() call (using as source a static "template", which corresponds to the initialiser list). Under the C99 rules, the compiler potentially has to emit an arbitrarily complicated block of initialisation code.
A: With Visual C, the code works. However, it generates a level 4 warning C4204, meaning they consider this is a Microsoft-specific extension to the C-standard. As caf and AndreyT said, it is not part of the C standard to allow this.
EDIT: With C standard I mean C89. | unknown | |
d13523 | train | Instead of null for the second parameter (URI):
TvView view = new TvView(this);
view.tune("com.mediatex.tvinput/.hdmi.HDMInputService/HW2", null);
You need to make and send a valid Uri:
TvView view = new TvView(this)
mInitChannelUri = TvContract.buildChannelUriForPassthroughInput("com.mediatex.tvinput/.hdmi.HDMInputService/HW2")
view.tune("com.mediatex.tvinput/.hdmi.HDMInputService/HW2", mInitChannelUri)
It's a little goofy because you basically send the same input name string twice. But this works for me.
Finally, to be TV brand independent you should use the input id parameter instead of static string constants (left as an exercise for the reader haha)
A: You don't need to use TvView. Just use an implicit intent with ACTION_VIEW.
I tested this code on my Sony TV and it worked well. (I am using Kotlin)
// Passthrough inputs are "hardware" inputs like HDMI / Components. Non-passthrough input are
// usually internal tv tuners. You can also filter out non-passthrough inputs before this step.
val uri =
if (inputInfo.isPassthroughInput) TvContract.buildChannelUriForPassthroughInput(inputInfo.id)

A: You can use the datepart function to look at the hour:
SELECT WORKORDERID ,
DESCRIPTION ,
actualstartdate ,
actualfinishdate
FROM [CityWorks].[AZTECA].[WORKORDER]
WHERE actualstartdate BETWEEN '2014-05-05 01:00:00.000'
AND '2014-06-05 23:00:00.000'
AND (DATEPART(HOUR, actualstartdate) <= 6
OR DATEPART(HOUR, actualstartdate) => 16)
ORDER BY actualstartdate DESC
A: Select WORKORDERID, DESCRIPTION, actualstartdate, actualfinishdate
FROM [CityWorks].[AZTECA].[WORKORDER]
WHERE actualstartdate BETWEEN '2014-05-05 01:00:00.000' AND '2014-06-05 23:00:00.000'
and
(CONVERT(time,actualstartdate )<'06:00' or CONVERT(time,actualfinishdate )> '16:00')
order by actualstartdate desc
A: You can easily get the hour portion of the date as follows:
DATEPART(hh, actualstartdate);
Use it as follows:
Select WORKORDERID, DESCRIPTION, actualstartdate, actualfinishdate
FROM [CityWorks].[AZTECA].[WORKORDER]
WHERE actualstartdate BETWEEN '2014-05-05 01:00:00.000' AND '2014-06-05 23:00:00.000'
AND (DATEPART(hh, actualstartdate) < 6 or (DATEPART(hh, actualfinishdate) >= 16)
order by actualstartdate desc
This will get all rows between your given dates that occurred before six in the morning or after four at night.
Edit:
If you want to allow an actualfinishdate of exactly 16 hundred you can change the second clause to:
or actualfinishdate > DATEADD(hh, 16, cast(actualfinishdate as date))
This would check if the actual finish date is after 4. | unknown | |

d13530 | train | Without details I can provide a conceptual solution.
Initialize the variable that holds the text to:
txt = '';
Then the callback will do:
txt = strtrim(sprintf('%s %s',txt, get(handleToTextBox,'String')));
A: letter = get(handles.edit1, 'string');
global txt;
txt=[txt letter];
txt=[txt ' '];
set(handles.text1, 'string', txt);

d13531 | train | makeApolloClient isnt a function, the file just exports an instance of the apollo client. Just import it as if it's a variable.
import client from './app/config/apollo'
export default function App() {
return (
<ApolloProvider client={client}>
<Routes />
</ApolloProvider>
);
}
A:
Storing JWT in local storage and session storage is not secure!
Use cookie with http-only enabled!
This code automatically reads and sets Authorization header after localStorage.setItem('jwt_token', jwt_token) in SignIn mutation.
import {ApolloClient, createHttpLink} from "@apollo/client";
import {setContext} from "@apollo/client/link/context";
import {InMemoryCache} from "@apollo/client";
const apolloHttpLink = createHttpLink({
uri: process.env.REACT_APP_APOLLO_SERVER_URI || 'http://localhost/graphql',
})
const apolloAuthContext = setContext(async (_, {headers}) => {
const jwt_token = localStorage.getItem('jwt_token')
return {
headers: {
...headers,
Authorization: jwt_token ? `Bearer ${jwt_token}` : ''
},
}
})
export const apolloClient = new ApolloClient({
link: apolloAuthContext.concat(apolloHttpLink),
cache: new InMemoryCache(),
})
A: Apollo usequery has a context option that allows you to dynamically change or update the values of the header object.
import { ApolloClient, InMemoryCache } from "@apollo/client";
const client = new ApolloClient({
cache: new InMemoryCache(),
uri: "/graphql"
});
client.query({
query: MY_QUERY,
context: {
// example of setting the headers with context per operation
headers: {
special: "Special header value"
}
}
});
The code above was copied from the Apollo docs.
To find out more check out https://www.apollographql.com/docs/react/networking/advanced-http-networking/#overriding-options
A: Try this
const authLink = setContext(async (_, { headers }) => {
const token = await AsyncStorage.getItem('token');
return {
headers: {
...headers,
authorization: token ? `Bearer ${token}` : "",
}
}
});
A: In React Native, AsyncStorage methods are async not like localStorage in Web. And the other methods doesn't work, except this.

d13532 | train | To estimate the distribution of that sum, you can repeatedly sample with replacement (and then take the sum of) n variates from sample_data. (sample() places equal probability mass on each element of sample_data, just as the ecdf does, so you don't need to calculate ecdf(sample_data) as an intermediate step.)
# Create some example data
sample_data <- runif(100)
n <- 10
X <- replicate(1000, sum(sample(sample_data, size=n, replace=TRUE)))
# Plot the estimated distribution of the sum of n variates.
hist(X, breaks=40, col="grey", main=expression(sum(x[i], i==1, n)))
box(bty="l")
# Plot the ecdf of the sum
plot(ecdf(X))
A: First, generalize and simplify: solve for step function CDFs X and Y, independent but not identically distributed. For every step jump xi and every step jump yi, there will be a corresponding step jump at xi+yi in the CDF of X + Y, So the CDF of X + Y will be characterized by the list:
sorted(x + y for x in X for y in Y)
That means if there are k points in X's CDF, there will be kn in (X1 + ... + Xn). We can cut that down to a manageable number at the end by throwing away all but k again, but clearly the intermediate calculations will be costly in time and space.
Also, note that even though the original CDF is an ECDF for X, the result will not be an ECDF for (X1 + ... + Xn), even if you keep all kn points.
In conclusion, use Josh's solution. | unknown | |

d13534 | train | I would recommend a fresh install of your IDE, which can be done by:
*
*Find the NetBeans Project folder in My Documents
*Copy that to another location
*Un-install the IDE from Control Panel
*Restart you PC
*Download the php version here
*Install it, start your IDE and just copy paste the project to the folder created in My Document for NetBeansProject
As far the preferences are concerned, if they are not very hard to create once again, a fresh install is good to go with as removal of the other modules like C, C++, or Java from IDE directly would still keep some files or cache(NetBeans version dependent) which would still hamper your PC sometimes.
A: For installing Netbeans first of all you must have a latest version of Java SDK installed on your PC.After that if you want to gain the data you must have the backup of the www folder which gets created while installation. After that in Netbeans you can start a project and then copy-paste your created pages(php,html,css,js) in that project. And you are all set to start from where you left off. | unknown | |
d13535 | train | You can try like this:

email = kwargs.pop('email')
user = super(RegistrationForm, self).save(commit=False)
user.set_password(self.cleaned_data['password1'])
user.email = email
user.save()
return user
# View
# your form codes...
if form.is_valid():
form.save(email=request.session.get('email'))
# rest of the codes

d13536 | train | If I were you, I would use the .split() method to create a list from the text you read.
test = re.sub('\ |1|2|3|4|5|6|7|8|9|0|>|s|e|q|:', "", holder)
newone = test.split("\n")
at this point newone will look like ['', 'ATATAT', '', 'GGGGG', '', 'TTTTT', ''] so to strip out the extra spaces:
newone = [x for x in newone if x != '']
Now to the error you are receiving, it is because you in your list comprehension (line 38 of your code) you are using newone instead of line. Each letter of line is an key of your dictionary base_to_integer but the KeyError you get is because \n is not a Key in the dictionary. Even after making the change I suggest above you will get an error:
KeyError: 'ATATAT'
So you should change this line to:
integer_encoded = [base_to_integer[y] for y in line]
Fixing this gives me:
[1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0]
[0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1]
[0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0]

d13539 | train | So, I've found out how. Once the "new user" installs my app and signs up with his facebook account I can execute this
GraphRequest request = GraphRequest.newGraphPathRequest(
accessToken,
"/me/apprequests",
new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse response) {
// process the info received

request.executeAsync();
The above code will get all/any apprequests from my app only and I only have to check who sent it etc.
A: If the App is already installed on the device, are you getting the identity of the "User" who invited the "Friend"? If yes, how are you doing this?
Secondly, Applink will only pass the information if it is opened through the notification on Facebook, and not directly through the home screen. | unknown | |

*Put your cats into a Map<Integer, Cat>
*Get the values of the resulting Map
*If you really need a List create a new List from the values of the Map
Here is how to merge the lists as you want to be able to over write:
Map<Integer, Cat> map = new HashMap<>();
for (Cat cat : catsLegs) {
map.put(cat.getId(), cat);
}
for (Cat cat : catsHeads) {
map.put(cat.getId(), cat);
}
Collection<Cat> cats = map.values();
// If you really need a List, you create a new one as next
List<Cat> catsList = new ArrayList<>(cats);
A: The simplest way is to loop through the List of cats and check if (catHead.id == catTail.id) but that's not really cool.
A better solution is to store your data inside a HashMap instead of a List. This way you can use the Hash Key to be the ID and the Hash Value to be the Cat object. Retrieving the object is much easier this way and it is of course much faster.
A: This is what I made. It transfers all the objects heads and I have fresh catList.size() because I don't want old currentCats objects be in final list.
public static void updateCats(List<Cat> catsFromServer) {
setAllCatsLegs(catsFromServer);
List<Cat> currentCats = getAllCats();
for (Cat currentCat : currentCats) {
for (Cat fromServer : catFromServer) {
if (currentCat.equals(fromServer)) {
fromServer.setHeads(currentcat.getHeads());
}
}
}
Contact.saveMultiple(contactsFromServer);
}
upd:
List<Cat> currentCats = getAllCats();
for (Cat cat : catsFromServier) {
int index = currentCats.indexOf(cat);
if (index != -1) {
cat.setHeads(currentCats.get(index).getHeads);
}

d13542 | train | Finally, I try One solution to solve this issue (this is not exact solution i try only to solve cached file redirects), actually problem occurs due to browser cache memory not in above htaccess. (Preciously I had try in both incognito and cache cleared browser but it still these redirects happens in some files) so i try to change name of these files in above screen shoot then reload it after that this problem is solved.
my guess is this problem is happens due to cache. because previously we used leverage browser caching in htaccess after that this was removed due to solve the problem.

d13544 | train | An applicative lets you apply a function in a context to a value in a context. So for instance, you can apply some((i: Int) => i + 1) to some(3) and get some(4). Let's forget that for now. I'll come back to that later.
List has two representations, it's either Nil or head :: tail. You may be used to fold over it using foldLeft but there is another way to fold over it:
def foldr[A, B](l: List[A], acc0: B, f: (A, B) => B): B = l match {
case Nil => acc0
case x :: xs => f(x, foldr(xs, acc0, f))
}
Given List(1, 2) we fold over the list applying the function starting from the right side - even though we really deconstruct the list from the left side!
f(1, f(2, Nil))
This can be used to compute the length of a list. Given List(1, 2):
foldr(List(1, 2), 0, (i: Int, acc: Int) => 1 + acc)
// returns 2
This can also be used to create another list:
foldr[Int, List[Int]](List(1, 2), List[Int](), _ :: _)
//List[Int] = List(1, 2)
So given an empty list and the :: function we were able to create another list. What if our elements are in some context? If our context is an applicative then we can still apply our elements and :: in that context. Continuing with List(1, 2) and Option as our applicative. We start with some(List[Int]())) we want to apply the :: function in the Option context. This is what the F.map2 does. It takes two values in their Option context, put the provided function of two arguments into the Option context and apply them together.
So outside the context we have (2, Nil) => 2 :: Nil
In context we have: (Some(2), Some(Nil)) => Some(2 :: Nil)
Going back to the original question:
// do a foldr
DList.fromList(l).foldr(F.point(List[B]())) {
// starting with an empty list in its applicative context F.point(List[B]())
(a, fbs) => F.map2(f(a), fbs)(_ :: _)
// Apply the `::` function to the two values in the context
}
I am not sure why the difference DList is used. What I see is that it uses trampolines so hopefully that makes this implementation work without blowing the stack, but I have not tried so I don't know.
The interesting part about implementing the right fold like this is that I think it gives you an approach to implement traverse for algebric data types using catamorphisms.
For instance given:
trait Tree[+A]
object Leaf extends Tree[Nothing]
case class Node[A](a: A, left: Tree[A], right: Tree[A]) extends Tree[A]
Fold would be defined like this (which is really following the same approach as for List):
def fold[A, B](tree: Tree[A], valueForLeaf: B, functionForNode: (A, B, B) => B): B = {
tree match {
case Leaf => valueForLeaf
case Node(a, left, right) => functionForNode(a,
fold(left, valueForLeaf, functionForNode),
fold(right, valueForLeaf, functionForNode)
)
}
}
And traverse would use that fold with F.point(Leaf) and apply it to Node.apply. Though there is no F.map3 so it may be a bit cumbersome.
A: This not something so easy to grasp. I recommend reading the article linked at the beginning of my blog post on the subject.
I also did a presentation on the subject during the last Functional Programming meeting in Sydney and you can find the slides here.
If I can try to explain in a few words, traverse is going to traverse each element of the list one by one, eventually re-constructing the list (_ :: _) but accumulating/executing some kind of "effects" as given by the F Applicative. If F is State it keeps track of some state. If F is the applicative corresponding to a Monoid it aggregates some kind of measure for each element of the list.
The main interaction of the list and the applicative is with the map2 application where it receives a F[B] element and attach it to the other F[List[B]] elements by definition of F as an Applicative and the use of the List constructor :: as the specific function to apply.
From there you see that implementing other instances of Traverse is only about applying the data constructors of the data structure you want to traverse. If you have a look at the linked powerpoint presentation, you'll see some slides with a binary tree traversal.
A: List#foldRight blows the stack for large lists. Try this in a REPL:
List.range(0, 10000).foldRight(())((a, b) => ())
Typically, you can reverse the list, use foldLeft, then reverse the result to avoid this problem. But with traverse we really have to process the elements in the correct order, to make sure that the effect is treated correctly. DList is a convenient way to do this, by virtue of trampolining.
In the end, these tests must pass:

d13546 | train | This is expiration of the session key, which is different than timestamp. For example of you turn establishSecurityContext off (or not use CreateSecureConversationSecurity) you should not get this exception.
Otherwise try to increase additional values such as InactivityTimeout, IssuedCookieLifetime, NegotiationTimeout, SessionKeyRenewalInterval and SessionKeyRolloverInterval.
If you turn on WCF trace on the server and see the exact stack trace of the error maybe we can dril down to the exact property. | unknown | |
d13547 | train | There is no direct way. But you could publish your own Observable. The main problem is, you need to return a value in the example function.
One solution could be to create an Observable in which you pass a TaskCompletionSource. This would allow you to set the result from the Event handler.
public class Request
{
public int Parameter { get; }
public Request(int parameter)
{
Parameter = parameter;
}
public TaskCompletionSource<IHttpActionResult> Result { get; } = new TaskCompletionSource<IHttpActionResult>();
}
public class Handler
{
public Subject<Request> ExampleObservable { get; } = new Subject<Request>();
[Route("{id}")]
[AcceptVerbs("GET")]
public async Task<IHttpActionResult> example(int id)
{
var req = new Request(id);
ExampleObservable.OnNext(req);
return await req.Result.Task;
}
}
In the example above, we push a Request in the ExampleObservable. You can subscribe to this and use Request.Result.SetResult(...) to return the request.
ExampleObservable.Subscribe(req => req.Result.SetResult(Ok(Service.GetExample(id))); | unknown | |

d13549 | train | The working directory should not have to be the directory that contains your DLLs. In fact, you definitely don't want that to be a requirement for running your application. Not only is it a hugely unexpected failure mode, but it could also be a potential security risk.
Put the required DLLs in the same directory as your application's executable. That's the first place that the loader will look. If necessary, use a post-build event in your library projects to copy them there.

d13550 | train | As already mentioned by @ForceBru, you need a python webserver.
If this can be useful to you, this is a possible unsecure implementation using flask:
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/turnOn')
def hello_world():
k = request.args.get('key')
if k == "superSecretKey":
# Do something ..
return 'Ok'
else:
return 'Nope'
If you put this in an app.py name file and, after having installed flask (pip install flask), you run flask run you should be able to see Ok if visiting the url http://localhost:5000/turnOn?key=superSecretKey .
You could write a brief html gui with a button and a key field in a form but I leaves that to you (you need to have fun too!).
To avoid potential security issues you could use a POST method and https.
Look at the flask documentation for more infos. | unknown | |

d13552 | train | There are a few issues here. The = operator is the match operator, it is not assignment. To explain the error, syntax-wise, this looks like function invocation on the left hand side of a match, which is not allowed.
But this is besides the point of your actual goal. If you want a set of user models that are updated with the new bcrypt information, you need to use a map function:
users = Enum.map(users, fn %User{id: id}=user ->
%User{user| token: Comeonin.Bcrypt.hashpwsalt("#{id}")}
end)
You have to remember that everything in Elixir is immutable. | unknown | |
d13553 | train | First, documentation. If the parameter is variadic, the user now needs to check some other source to find out that this really wants something that will takes one template parameter.
Second, early checking. If you accidentally pass two arguments to T in S, the compiler won't tell you if it's variadic until a user actually tries to use it.
Third, error messages. If the user passes a template that actually needs two parameters, in the variadic version the compiler will give him an error message on the line where S instantiates T, with all the backtrace stuff in-between. In the fixed version, he gets the error where he instantiates S.
Fourth, it's not necessary, because template aliases can work around the issue too.
S<vector> s; // doesn't work
// but this does:
template <typename T> using vector1 = vector<T>;
S<vector1> s;
So my conclusion is, don't make things variadic. You don't actually gain flexibility, you just reduce the amount of code the user has to write a bit, at the cost of poorer readability.
A: If you know already that you will need it with high probability, you should add it. Otherwise, You Ain't Gonna Need It (YAGNI) so it would add more stuff to maintain. It's similar to the decision to have a template parameter in the first place. Especially in a TDD type of environment, you would refactor only when the need arises, rather than do premature abstraction.
Nor is it a good idea to apply rampant abstraction to every part of
the application. Rather, it requires a dedication on the part of the
developers to apply abstraction only to those parts of the program
that exhibit frequent change. Resisting premature abstraction is as
important as abstraction itself

d13555 | train | Turns out you need to use Plaintext form.
A: This error can occur when one or more pre-requisites for creating the secret has not been followed. There are a few pre-requisites when creating the secret. AWS document for reference. Listing them below for quick access.
*
*Choose Other type of secrets (e.g. API key) for the secret type.
*Your secret name must have the prefix AmazonMSK_
*Your user and password data must be in the following format to enter key-value pairs using the Plaintext option.
{
"username": "alice",
"password": "alice-secret"
}
A: In addition to @Sourabh 's answer,
a secret created with the default AWS KMS key cannot be used with an Amazon MSK cluster,
so what you need to do is:
*
*Open the Secrets Manager console.
*In Secret name, choose your secret.
*Choose Actions, and then choose dropdown list, select the AWS KMS key, select the check box for Create new version of secret with new encryption key, and then choose Save.
that should solve this error
Amazon MSK failed to associate 1 secret for cluster sasl-cluster. Wait
for a few minutes and try again. If the problem persists, see AWS
Support Center . API Response : The provided secret is encrypted with
the default key. You can't use this secret with Amazon MSK.
A: This is happening because at the time of secret creation you had selected the default aws kms option.
Frist you have to create the new KMS
then you have to update it in secret manager creation time.
After following all you will not get this error. | unknown | |

d13557 | train | The problem with your query is that
AND rd.CandidateID = 9
on the WHERE clause effectively "kills" the full join by requiring that RoundDetails be present.
Move this part of the condition into the ON clause of the join, and replace the join with LEFT OUTER, because you do not need a full outer join anyway:
select
q.QuestionID
, q.TotalMarks
, q.Question
, isnull(rd.MarksObtained, 0) MarksObtained
, convert(bit, isnull(rd.QuestionID, 0)) Attended
from Questions q
left outer join RoundDetails rd
ON q.questionID = q.questionID AND rd.CandidateID = 9
where
q.SubjectID = 2 AND q.IsActive = 1
As a general rule, you should be extremely careful adding conditions on outer-joined tables in the WHERE clause, because any condition that is not null-preserving will convert your outer join to an inner join.
A: Different SQL JOINs
INNER JOIN: Returns all rows when there is at least one match in BOTH tables
LEFT JOIN: Return all rows from the left table, and the matched rows from the right table
RIGHT JOIN: Return all rows from the right table, and the matched rows from the left table
FULL JOIN: Return all rows when there is a match in ONE of the tables
As you are using Full Join you will only get the questions that have an answer attempted. you need to use a Left Join instead.

*explode() splits the string $input[0] using comma (,) as delimiter and returns an array;
*array_chunk() splits the array into chunks of size 3; it returns an array of arrays, each inner array contains 3 elements (apart from the last one that can contain less);
*array_map() applies the function it receives as its first argument to each value of the array it gets as its second argument (the array of arrays returned by array_chunk()); it returns an array whose values are the values returned by the function;
*the anonymous function passed to array_map() gets an array (of size 3 or less) and uses implode() to join its elements into a string, using comma (,) to separate the values and returns the string;
*array_map() puts together all the values returned by the anonymous function (one for each chunk of 3 elements of the array) into a new array it returns.
The output (print_r($output)) looks like this:

bin2 13200 0 0 16766 200344
The df.fillna(0) replaces missing values with 0.
A: You can use d[j].get(q, '0') instead of d[j][q] to fill in 0 for all missing entries:
# print the table header
labs = sorted(max(d.values(), key=len))
print "bin" + "\t" + "\t".join(labs)
# loop and print the values
for j in d:
print j + "\t" + "\t".join(str(d[j].get(q, '0')) for q in labs)

d13584 | train | I suggest bigger chars for smaller screens!
A: Just to expand on my comment. ( not an answer as subjective )
Using ems for width can tell us how many font characters wide a containing element is.
consider
<style>
body { font size: 0.8em; } /* roughly about 14 px */
.container { width: 30em; } /* 1em now equals 0.8 */
</style>
we now know ( or as close as possible ) , that the <div class="container"> .. </div> can hold text with lines of ( close to ) 30 characters.
The good part here is that if we change the font size :
<style>
body { font size: 1.2em; }
</style>
The container width also changes and we retain our set number of characters per line.
Because of this we have a connection between layout and typography and have control over "fixing" paragraph lengths and spacing within our designs.
Quite useful when we need to calculate heights, widths and our designed 'page breaks' of layout elements based on layouts that adapt to different sizes and are dealing with dynamic text and font sizes.

d13590 | train | Markov chains aren't guaranteed to have unique stationary distributions. For example, consider a two state Markov Chain where the transition matrix is the identity matrix. That means that whatever the initial state is, it never changes. So in that case there is no stationary distribution that is independent of the initial case.
Where there is a stationary distribution, unless the initial state is the stationary distribution, the stationary distribution is only reached in the limit as n tends to infinity. So iteration n+1 will be closer to it that iteration n, but however large n is, it won't ever actually be the stationary distribution. However, for practical purposes (i.e. to the limit of the accuracy of floating point numbers in computers), the stationary state may well be reached after a handful of iterations.
A: You need the underlying graph to be strongly connected and aperiodic. If you want to find the stationary distribution of a periodic Markov chain just by running some chain, add "stay put" transitions with some constant probability to each node and scale the other transitions down appropriately. | unknown | |

So if both servers are in "foobar" domain, and the web box is "bicycle", the login used to the SQL Server Instance is foobar\bicycle$
If you aren't in a domain, then there is no common directory to authenticate against. Use a SQL login with username and password for simplicity
Edit, after comment
If the domains are trusted then you can use the machien account still (use domain local groups for SQL Server, into which add a global groups etc)
As for using app pool identities, they are local to your web server only as per article. They have no meaning to SQL Server. If you need to differentiate sites, then use proper domain accounts for the App Pools.

d13594 | train | Array.prototype.join() works on array and to insert an element to array you should call .push() instead of +=, read more about += here.
Always use var before declaring variables, or you end up declaring global variables.

for (i = 1800; i < 2018; i++) {
birthyear.push(i);
}
var birth = birthyear.join(", ");
document.write(birth);
A: I your code your not appending data to array you are adding data to array variable which is wrong
1st Way
birthyear=[];
for(i=1800;i<2018;i++)
{
birthyear.push(i);
}
birth=birthyear.join();
document.write(birth);
2nd Way
birthyear=[];
k=0;
for(i=1800;i<2018;i++){
birthyear[k++]=i;
}
birth=birthyear.join();
document.write(birth);
A: You can't apply .push() to a primitive type but to an array type (Object type).
You declared var birthyear = []; as an array but in the body of your loop you used it as a primitive: birthyear+=i;.
Here's a revision:
var birthyear=[];
for(let i=1800;i<2018;i++){
birthyear[i]=i;
// careful here: birthyear[i] += i; won't work
// since birthyear[i] is NaN

d13597 | train | The main difference between EXPECT_* and ASSERT_* macros is that assertions stop the test immediately if it failed, while expectations allow it to continue.
Here's what GoogleTest Primer says about it:
Usually EXPECT_* are preferred, as they allow more than one failures to be reported in a test. However, you should use ASSERT_* if it doesn't make sense to continue when the assertion in question fails.
So, to illustrate it:
TEST_F(myTest, test1)
{
uut.doSomething();
ASSERT_EQ(uut.field1, expectedvalue1);
ASSERT_EQ(uut.field2, expectedvalue2);
}
If field1 doesn't match assertion, test fails and you have no idea if field2 is correct or not. This makes debugging much more difficult.
Choice between these options is mostly matter of agreement in your team, but I'd stick to GTest proposition of using EXPECT_* as the backbone of all checks and ASSERT_* only if you test something crucial to continue, without which further part of test doesn't make any sense (for example, if your unit under test was not created correctly). | unknown | |
d13598 | train | So, this isn't actually a questing about bs4, but more about how to handle data structures in python.
Your script lacks the part that loads the data you already know. One way to go about this would be the build a dict that has all your hrefs as keys and then the count as value.
So given a csv with rows like this...
href,seen_count
https://google.com/1234,4
https://google.com/3241,2
... you first need to build the dict
csv_list = list(open("cms_scrape.csv", "r", encoding="utf-8"))
# we skip the first line, since it hold your header and not data
csv_list = csv_list[1:]
# now we convert this to a dict
hrefs_dict = {}
for line in csv_list:
url, count = line.split(",")
# remove linebreak from count and convert to int
count = int(count.strip())
hrefs_dict[url] = count
That yields a dict like this:
{
"https://google.com/1234": 4,
"https://google.com/3241": 2
}
Now you can check if all hrefs you come across exist as a key in this dict. If yes - increase the count by one. If no, insert the href in the dict and se the count to 1.
To apply this to your code I'd suggest you scrape the data first and write to file once all scraping is completed. Like so:
for i in tqdm(links):
#print("beginning of crawler code")
r = requests.get(i)
data = r.text
soup = BeautifulSoup(data, 'lxml')
all_a = soup.select('.carousel-small.seo-category-widget a')
for a in all_a:
href = a['href']
print(href)
# if href is a key in hrefs_dict increase the value by one
if href in hrefs_dict:
hrefs_dict[href] += 1
# else insert it into the hrefs_dict and set the count to 1
else:
hrefs_dict[href] = 1
Now when the scraping is done, go through every line in the dict and write it to your file. It's generally recommended that you use context managers when you write to files (to avoid blocking if you accidentally forget to close the file). So the "with" takes care of both the opening and closing of the file:
with open('cms_scrape.csv', 'w') as csv_file:
csv_writer = csv.writer(csv_file)
csv_writer.writerow(['hrefs', 'Number of times seen:'])
# loop through the hrefs_dict
for href, count in hrefs_dict.items():
csv_writer.writerow([href, count])
So if you don't actually have to use a csv-file for this I'd suggest using JSON or Pickle. That way you can read and store the dict without needing to convert back and forth to csv.
I hope this solves your problems... | unknown | |
d13599 | train | The JSON support in the standard Scala library is probably not the best choice. Unfortunately the situation with JSON libraries for Scala is a bit confusing, there are many alternatives (Lift JSON, Play JSON, Spray JSON, Twitter JSON, Argonaut, ...), basically one library for each day of the week... I suggest you have a look at these at least to see if any of them is easier to use and more performative.
Here is an example using Play JSON which I have chosen for particular reasons (being able to generate formats with macros):
object JsonTest extends App {
import play.api.libs.json._
type MyDict = Map[String, Int]
implicit object MyDictFormat extends Format[MyDict] {
def reads(json: JsValue): JsResult[MyDict] = json match {
case JsObject(fields) =>
val b = Map.newBuilder[String, Int]
fields.foreach {
case (k, JsNumber(v)) => b += k -> v.toInt
case other => return JsError(s"Not a (string, number) pair: $other")
}
JsSuccess(b.result())
case _ => JsError(s"Not an object: $json")
}
def writes(m: MyDict): JsValue = {
val fields: Seq[(String, JsValue)] = m.map {
case (k, v) => k -> JsNumber(v)
} (collection.breakOut)
JsObject(fields)
}
}
val m = Map("hallo" -> 12, "gallo" -> 34)
val serial = Json.toJson(m)
val text = Json.stringify(serial)
println(text)
val back = Json.fromJson[MyDict](serial)
assert(back == JsSuccess(m), s"Failed: $back")
}
While you can construct and deconstruct JsValues directly, the main idea is to use a Format[A] where A is the type of your data structure. This puts more emphasis on type safety than the standard Scala-Library JSON. It looks more verbose, but in end I think it's the better approach.
There are utility methods Json.toJson and Json.fromJson which look for an implicit format of the type you want.
On the other hand, it does construct everything in-memory and it does duplicate your data structure (because for each entry in your map you will have another tuple (String, JsValue)), so this isn't necessarily the most memory efficient solution, given that you are operating in the GB magnitude...
Jerkson is a Scala wrapper for the Java JSON library Jackson. The latter apparently has the feature to stream data. I found this project which says it adds streaming support. Play JSON in turn is based on Jerkson, so perhaps you can even figure out how to stream your object with that. See also this question. | unknown | |
