*Server side is needed for foolproofing this. On the server, when assessment is started, you should first have start screen URL. You must program it so that once assessment is started (after clicking start), it goes to the exam URL, and your assessment is always saved - when user goes back, using server side tricks have it so that instead of showing the start screen, it redirects back to the correct page (in a way that still maintains history), shows the exam with the data still in it, and pops up the warning not to click back button. Then, if user does it again, it does the same thing, again.
*You have to have it so the exam is saved all the time. unload javascript event can be used to notify via alert() that they shouldn't be leaving the exam, and thats about all. onbeforeunload event can be used to try to give them the choice to stay, but shouldn't be depended on as it doesn't work on every browser.
A: Use onbeforeunload as suggested in a comment. There are various example, like this one: https://web.archive.org/web/20211028110528/http://www.4guysfromrolla.com/demos/OnBeforeUnloadDemo1.htm

d13407 | train | If you have getter defined for the fields of Person, you can map the names:
List<String> personNames = list.stream().map(Person::getName).collect(Collectors.toList());
A: Use .filter, like the webiste explains you, instead of .map
A: To filter say on the name, do it like this.
Person{id=4, name=E, color=red}]
[Person{id=0, name=A, color=blue}
Person{id=1, name=B, color=green}
Person{id=2, name=D, color=pink}
Person{id=0, name=C, color=yellow
Assuming a List<Person>
To get all the Person objects with a specific name
List<Person> specific = list
.stream()
.filter(person->person.name.equals("E"))
.collect(Collectors.toList());
To get just the names
List<String> names = list
.stream()
.map(person->person.name)
.collect(Collectors.toList());
A: Here is a generic code, that uses filter:
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
class Person {
int id;
String name;
String color;
@Override
public String toString() {
// TODO Auto-generated method stub
return id + ":" + name + ":" + color;
}
public Person(int id, String name, String color) {
super();
this.id = id;
this.name = name;
this.color = color;
}
public int getId() {return id;}
public void setId(int id) {this.id = id;}
public String getName() {return name;}
public void setName(String name) {this.name = name;}
public String getColor() {return color;}
public void setColor(String color) {this.color = color;}
}
public class Test {
public static void main(String[] args) {
List<Person> list = new ArrayList<Person>();
list.add(new Person(1,"Ana","red"));
list.add(new Person(2,"tna","orange"));
list.add(new Person(3,"Hna","green"));
list.add(new Person(4,"Ana","blue"));
List<Person> t = list.stream().filter(p->p.getName().equals("Ana")).collect(Collectors.toList());
System.out.println(t);
}
}
For this particular question it is suggestible to use filter instead of map. Because we are only interested in filtering the stream to get the desired output.
On the other hand, map operation is used on the stream if we have the requirement to manipulate the data further in which condition we can apply more functions before the terminal operation (example is provided).
By using map, you transform the object values.
The map operation allows us to apply a function, that takes in a parameter of one type, and returns something else.
For an example:
Stream students = persons.stream()
.filter(p -> p.getAge() > 18)
.map(new Function<Person, Customer>() {
@Override
public Customer apply(Person person) {
return new Customer(person);
}
});
Filter is used for filtering the data, it always returns the boolean value. If it returns true, the item is added to list else it is filtered out.

d13409 | train | EF Core Interceptors allow you to do just that:
public class QueryCommandInterceptor : DbCommandInterceptor
{
public override async ValueTask<InterceptionResult<DbDataReader>> ReaderExecutingAsync(

CommandEventData eventData,
InterceptionResult<DbDataReader> result,
CancellationToken cancellationToken = default)

}
private Task<DbDataReader> SendCommandToAnotherAppAsync(DbCommand command)
{
// TODO: Actual logic.
Console.WriteLine(command.CommandText);
return Task.FromResult<DbDataReader>(null!);
}
}
Make sure to override other methods like ScalarExecuting, NonQueryExecuting, sync and async variants.
A: Multitenancy is already supported in EF Core. The options are described in the Multi-tenancy page in the docs.
In this case, it appears a different database per tenant is used. Assuming there's a way/service that can return who the tenant is, a DbContext can use a different connection string for each tenant. Assuming there's a way/service to retrieve the current tenant name, eg ITenantService, the DbContext constructor can use it to load a different connection string per tenant. The entire process could be abstracted behind eg an ITenantConnectionService, but the docs show how this is done explicitly.
The context constructor will need the tenant name and access to configuration :
public ContactContext(
DbContextOptions<ContactContext> opts,
IConfiguration config,
ITenantService service)
: base(opts)
{
_tenantService = service;
_configuration = config;
}
Each time a new DbContext instance is created, the connection string is loaded from configuration based on the tenant's name:
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
var tenant = _tenantService.Tenant;
var connectionStr = _configuration.GetConnectionString(tenant);
optionsBuilder.UseSqlite(connectionStr);
}
This is enough to use a different database per tenant.
Scope and lifecycle
These aren't a concern when a DbContext is used as a Scoped or Transient service.
By default AddDbContext registers DbContexts as scoped services. The scope in a web application is a single request. Once a request is processed, any DbContext instances created are disposed.
Connection Pooling
Connection pooling isn't a concern either. First of all, a DbContext doesn't represent a database connection. It's a disconnected Unit-of-Work. A connection is only opened when the context needs to load data from the database or persist changes when SaveChanges is called. If SaveChanges isn't called, nothing gets persisted. No connections remain open between loading and saving.
Consistency is maintained using optimistic concurrency. When the data is saved EF Core checks to see if the rows being stored have changed since the time they were loaded. In the rare case that some other application/request changed the data, EF Core throws a DbConcurrencyException and the application has to decide what to do with the changed data.
This way, there's no need for a database transaction and thus no need for an open connection. When optimistic concurrency was introduced in ... the late 1990s, application scalability increased by several (as in more than 100, if not 1000) orders of magnitude.
Connection pooling is used to eliminate the cost of opening and closing connections. When DbConnection.Close() is called, the actual network connection isn't terminated. The connection is reset and placed in a pool of connections that can be reused.
That's a driver-level feature, not something controlled by EF Core. Connections are pooled by connection string and in the case of Windows Authentication, per user. This eliminates the chance of a connection meant for one user getting used by another one.
Connection pooling is controlled by ADO.NET and the database provider. Some drivers allow connection pooling while others don't. In those that do support it, it can be turned off using keywords in the connection string or driver settings. | unknown | |

d13412 | train | If you load your KML through the API, with GGeoXml(), (V2), or KmlLayer(), (V3), then your data needs to be in a public server because it is parsed by Google's servers and they need to be able to get to it. If you load it with a third party extension then you can keep it private.
Third party extensions that can load and parse KML data are EGeoXml() by Mike Williams
http://econym.org.uk/gmap/extensions.htm#EGeoXml
and GeoXml() by Lance Dyas
http://www.dyasdesigns.com/geoxml/
but I believe that both of those are only available for the API V2 for now.
A: I just upgraded my Google Maps JavaScript API Application from v2 to v3, following these instructions.
My v2 application was using the EGeoXml extension referred to by @Marcelo in the accepted answer to locally parse KML data.
A substitution of geoxml3 in its place, as suggested by @geocodezip (a contributor to the project) in a comment, functioned immediately in my v3 application.

d13415 | train | All Lucene does is provide a way for "Documents" to be added into a structured index and for queries to be executed against that index.
The Nutch crawler (I assume that's what you mean by nutch) just provides an easy way to get unstructured data (ie a website) to get pushed into the index. Just like you can use Solr to easily push xml data into a lucene index.
Nutch plugins simply provide a hook were you can put customer logic. For instance the "parse-pdf" can convert a binary PDF file into one of these "lucene Documents". Basically all it does is use an API that can read PDF documents (pdfbox) to extract the text (this is similar to what "parse-html" does since html has a lot of parts that isn't text, for example all html tags).
So regarding your concern about binary formats, its not difficult to parse, just difficult to get something useful. For instance we can write a "parse-image" plugin that could extract a lot of info about the image (ie name, format, size), it's just that parsing the "face" or the "dog" in the picture is difficult. | unknown | |
d13416 | train | As long as you can fit all of the data in memory you're better off holding onto it all and sorting it in memory rather than writing it to a file. The concept of sorting data in a file is generally solved by "read it into memory, sort it, and write it back out again".
As for writing a CSV file, it's not really that hard. I like to use a StringBuilder to add on each of the fields for each line, and then once I have a line I append that line to the file. For the headers, you either hard code them if appropriate, or get them from whatever source you have if it's dynamic. Do you not know how to write to a file? My guess is the File.WriteAllText() and File.AppendText() methods will be all you should need for that.
Just a general tip, since you asked, is that rather than adding the items to the list, since you'll eventually sort them all, is to add them to a SortedList, so that they're sorted as you go. Then when you're done, you just get them one at a time and they are already in order.
A: You can use LINQ for the sorting and a StreamWriter for the file creation.
using (var writer = new StreamWriter(@"C:\files.csv")) {
writer.WriteLine("Name,Size"); // Header
var query = fileList.OrderBy(r => r.fileName);
foreach (Record record in query) {
writer.WriteLine("\"{0}\",{1}", record.fileName, record.fileSize);
}
}
Note that I enclosed the file name in double quotes ("), in the case that a comma (,) is part of the file name. The double quote itself is not a valid character for file names in Windows, so that it should not be a problem. | unknown | |

d13418 | train | In a Flex rule file, you'd use \\ to match a single backslash '\' character. This is because the \ is used as an escape character in Flex.
BACKSLASH \\
LITERAL_BACKSLASH \\\\
LITERAL_LESSTHAN \\\\<
LITERAL_GREATERTHAN \\\\>
LITERAL_VERTICALBAR \\\\|
If I follow you correctly, in your case you want "\>" to be treated as literal '>' but "\\>" to be treated as literal '\' followed by special redirect. You don't need negative look behind or anything particularly special to accomplish this as you can build one rule that would accept both your regular argument characters and also the literal versions of your special characters.
For purposes of discussion, let's assume that your argument/parameter can contain any character but ' ', '\t', and the special forms of '>', '<', '|'. The rule for the argument would then be something like:
ARGUMENT ([^ \t\\><|]|\\\\|\\>|\\<|\\\|)+
Where:
[^ \t\\><|] matches any single character but ' ', '\t', and your special characters
\\\\ matches any instance of "\" (i.e. a literal backslash)
\\> matches any instance of ">" (i.e. a literal greater than)
\\< matches any instance of "\<" (i.e. a literal less than)
\\\| matches any instance of "\|" (i.e. a literal vertical bar/pipe)
Actually... You can probably just shorten that rule to:
ARGUMENT ([^ \t\\><|]|\\[^ \t\r\n])+
Where:
[^ \t\\><|] matches any single character but ' ', '\t', and your special characters
\\[^ \t\r\n] matches any character preceded by a '\' in your input except for whitespace (which will handle all of your special characters and allow for literal forms of all other characters)
If you want to allow for literal whitespace in your arguments/parameters then you could shorten the rule even further but be careful with using \\. for the second half of the rule alternation as it may or may not match " \n" (i.e. eat your trailing command terminator character!).
Hope that helps!
A: You cannot easily extract single escaped characters from a command-line, since you will not know the context of the character. In the simplest case, consider the following:
LessThan:\<
BackslashFrom:\\<
In the first one, < is an escaped character; in the second one, it is not. If your language includes quotes (as most shells do), things become even more complicated. It's a lot better to parse the string left to right, one entity at a time. (I'd use flex myself, because I've stopped wasting my time writing and testing lexers, but you might have some pedagogical reason to do so.)
If you really need to find a special character which shouldn't be special, just search for it (in C++98, where you don't have raw literals, you'll have to escape all of the backslashes):
regex: (\\\\)*\\[<>|]
(An even number -- possibly 0 -- of \, then a \ and a <, > or |)
as a C string => "(\\\\\\\\)*\\\\[<>|]" | unknown | |

A: An gxt grid is able to show the data only of one data type. If you put a single TicketProxy row, how do you expect to access a user object?
If you want to display both Tickets and Users independently (so a row is either a Ticket OR a User), you have to use BaseEntityProxy in your Grid: Grid<BaseEntityProxy>. Then you can define your columns as ColumnConfig<BaseEntityProxy, ?> and check the type within your getters and setter:
List<ColumnConfig<BaseEntityProxy, ?>> columnsChamado = new ArrayList<ColumnConfig<BaseEntityProxy, ?>>();
ColumnConfig<BaseEntityProxy, String> dateColumn = new ColumnConfig<BaseEntityProxy, String>(
new ValueProvider<BaseEntityProxy, String>() {
private final DateTimeFormat dtFormat = DateTimeFormat.getFormat(DateTimeFormat.PredefinedFormat.DATE_FULL);

}
public String getPath() {

columnsChamado.add(dateColumn);
ColumnConfig<BaseEntityProxy, String> userRoomColumn = new ColumnConfig<BaseEntityProxy, String>(
new ValueProvider<BaseEntityProxy, String>() {
public String getValue(BaseEntityProxy object) {
String userRoom = ((UserProxy)object).getUserRoom();
String room = "";
if (userRoom != null) {
room = userRoom;
}
return room;

public void setValue(BaseEntityProxy object, String userRoom) {

public String getPath() {
return "userRoom";

columnsChamado.add(userRoomColumn);
ColumnModel<BaseEntityProxy> cm = new ColumnModel<BaseEntityProxy>(columnsChamado);
If, on the other hand, you want one grid row to display a User AND a Ticket, you have to use a wrapper class:
class TicketWithUserProxy extends BaseEntityProxy{
private UserProxy userProxy;
private TicketProxy ticketProxy;
public UserProxy getUserProxy() {
return userProxy;
}
public void setUserProxy(UserProxy userProxy) {
this.userProxy = userProxy;
}
public TicketProxy getTicketProxy() {
return ticketProxy;
}
public void setTicketProxy(TicketProxy ticketProxy) {
this.ticketProxy = ticketProxy;
}
}
and setup your grid (Grid<TicketWithUserProxy>) accordingly:
List<ColumnConfig<TicketWithUserProxy, ?>> columnsChamado = new ArrayList<ColumnConfig<TicketWithUserProxy, ?>>();
ColumnConfig<TicketWithUserProxy, String> dateColumn = new ColumnConfig<TicketWithUserProxy, String>(

d13426 | train | &array_month_count is a macro variable. In SAS, this is a string that is substituted at compile time. Macros "write" code.
It looks like all the errors you are getting are because that variable does not have a value.
So somewhere in the code, there should be something that sets the value of array_month_count. Find that, fix it, and this step should work.
A: A bit more detail than Dom's answer may be helpful, though his answer is certainly the crux of the issue.
&array_month_count needs to be defined, but you also probably have a few other issues.
array array1 [&array_month_count] $ 1 membsdemo_flag_&start_yrmo
membsdemo_flag_&end_yrmo;
This is probably wrong, or else this code is perhaps doing something different from what it used to: I suspect it is intended to be
array array1 [&array_month_count] $ 1 membsdemo_flag_&start_yrmo - membsdemo_flag_&end_yrmo;
In other words, it's probably supposed to expand to something like this.
array array1 [6] $ 1 membsdemo_flag_1701 membsdemo_flag_1702 membsdemo_flag_1703 membsdemo_flag_1704 membsdemo_flag_1705 membsdemo_flag_1706;
The 6 there isn't actually needed since the variables are listed out (in a condensed form). The dash tells SAS to expand numerically with consecutive numbers from the start to the end; it would only work if your yrmo never crosses a year boundary. It's possible -- is appropriate instead - it tells SAS to expand in variable number order, which works fine if you have consecutively appearing variables (in other words, they're adjacent when you open the dataset).
The 6 is however needed for the second bit.
do i=1 to &array_month_count;
Unless you rewrite it to this:
do i = 1 to dim(array1); *dim = dimension, or count of variables in that array;
In which case you really don't even need that value.
--
If it's actually intended to be the code as above, and only have 2 variables, then you don't need &array_month_count since it's known to be only 2 variables. | unknown | |
d13427 | train | Use a getBroadcast() PendingIntent, where the BroadcastReceiver calls stopService().
Or, use a getService() PendingIntent, where you send a command to your service that has the service call stopSelf().
Or, switch the service to an IntentService, so it shuts down automatically, if that is a better service implementation for your scenario. | unknown | |
d13428 | train | Gatsby comes with reach router, so you can use it to get location.pathname and then render something conditionally.
import React from 'react'
import { Location } from '@reach/router'
const HomepageOnly = () => (
<Location>
{({ location }) =>
location.pathname === '/' ? (
<p>This is the homepage</p>
) : (
<p>This is not</p>
)
}
</Location>
)
export default HomepageOnly
Codesandbox | unknown | |
d13429 | train | If you have a keytab file to authenticate to the cluster, this is one way I've done it:
val conf: Configuration: = new Configuration()
conf.set("hadoop.security.authentication", "Kerberos")
UserGroupInformation.setConfiguration(conf)
UserGroupInformation.loginUserFromKeytab("user-name", "path/to/keytab/on/local/machine")
FileSystem.get(conf)
I believe to do this, you might also need some configuration xml docs. Namely core-site.xml, hdfs-site.xml, and mapred-site.xml. These are somewhere usually under /etc/hadoop/conf/.
You would put those under a directory in your program and mark it as Resources directory in IntelliJ. | unknown | |
d13430 | train | You check K_UP for second player in KEYUP but it has to be K_w and K_s.
Besides you don't have to check player_paddle2.direction
if event.type == KEYUP:
if event.key == K_UP:
player_paddle1.direction = 0
elif event.key == K_DOWN:
player_paddle1.direction = 0
elif event.key == K_w: # <-- there was K_UP
print("The key is now up!")
player_paddle2.direction = 0
elif event.key == K_s: # <-- there was K_UP
player_paddle2.direction = 0
it can be shorter
elif event.type == KEYUP:
if event.key in (K_UP, K_DOWN)
player_paddle1.direction = 0
elif event.key in (K_w, K_s):
player_paddle2.direction = 0
BTW: you can use elif in some places. | unknown | |
d13431 | train | Why dont you create a function in the user around the lines of:
public function autologin() {
$this->autoRender = false;
if ($this->request->is('post')) {
if ($this->Auth->login()) {
$cuser = $this->Auth->user();
$this->Session->write('Udata', $udata);
$fD = array('loggedIn'=>true,'vdata'=>$udata);
} else {
$fD = array('loggedIn'=>false,'vdata'=>'Your username/password combination was incorrect');
}
echo json_encode($fD);
}
}
and call this page with your ajax. with the JSON run some check; | unknown | |
d13432 | train | I answer to my question with my solution. @pedrofb tell a better way to fix my problem but I couldn't use on my WAS server.
I use a private method to canonicalized my XML to create the digest and later to create the signature:
private String canonicalize(String xml)
{
try
{
String CHARSET = "UTF-8";
Init.init();
Canonicalizer canon = Canonicalizer.getInstance(Canonicalizer.ALGO_ID_C14N_EXCL_WITH_COMMENTS);
String canoninalizacion = new String(canon.canonicalize(xml.getBytes(CHARSET)), CHARSET);
return canoninalizacion;
}
catch (Exception e)
{
e.printStackTrace();
return xml;
}
}
Then we transform the XML correctly to set the namespaces and prefix in the right place. For my needed I use:
private String createBodyXML(String dataXML)
{
String docXML = canonicalize(dataXML);
// Manual introduction of prefixes
docXML = docXML.replaceAll("</", "</ns2:").replaceAll("<", "<ns2:").replaceAll("<ns2:/ns2:", "</ns2:");
String startBodyHash = "<soap:Body xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" Id=\"MsgBody\">";
String endBodyHash = "</soap:Body>";
String dataXMLSoap = "<SERVICE_DISPATCHER_REQUEST xmlns=\"http://inti.notariado.org/XML\">"
+ "<ns2:SERVICIO_CONSIGNACION_NOTARIAL xmlns:ns2=\"http://ancert.notariado.org/XML/CSN\">"
+ docXML
+ "</ns2:SERVICIO_CONSIGNACION_NOTARIAL>"
+ "</SERVICE_DISPATCHER_REQUEST>";
String xmlHash = startBodyHash + dataXMLSoap + endBodyHash;
// this xmlHash is the same body of the SOAP call
return xmlHash;
}
We do at the time of the creation of the XML of body and XML of signedInfo. Is not the best way to make it:
String xmlDigest = "<ds:SignedInfo xmlns:ds=\"http://www.w3.org/2000/09/xmldsig#\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
+ "<ds:CanonicalizationMethod Algorithm=\"http://www.w3.org/2001/10/xml-exc-c14n#\">"

A: You need to perform a compliant ws-security SOAP message which includes a XML DSig Signature
You are not building the message digest correctly and you do not apply the canonicalization methods neither transforms. Java has native support for XML signatures. You do not need to build them from scratch.
In this post you will find an example using standard Java code and a link to the utilities of your application server(recommended)
A: I'm enhancing https://stackoverflow.com/a/63617195/5845739 Yash's Answer.
Thank You for the excellent answer.
Also, I'm directly calling the SOAP Message, instead of using the File Call in the
callTheWebServiceFromFile()

or with numpy - like @ayhan says - which has also a logical and reduction:
from numpy import logical_and

d13434 | train | I had the same issue as you are presenting, and after a lot of trial and error, i found some simple steps to fix it.
First, add to your Gemfile:
gem 'sqlite3', '1.3.5'
Then run in your console:
bundle install
And then you should proceed normally
A: Ruby 2.0 has problems with sqlite3 and can't run. If you need to use sqlite3 you'll have to downgrade to 1.9.3. I don't have the link to the documentation about this, but I know if you downgrade to 1.9.3 you'll be fine. I'll see if I can find the link.
A: You cannot install activerecord-sqlite3-adapter as a gem, because this adapter is included with ActiveRecord already. The problem is not in activerecord-sqlite3-adapter, but in that you don't have sqlite3 as part of your Gem bundle (the error message tells us this at the end: "sqlite3 is not part of the bundle.")
To fix it, add it to your Gemfile first:
# in your Gemfile
gem 'sqlite3'
then run from command line:
$ bundle install
Ensure that sqlite3 installs correctly and shows up in your Gem bundle, and everything should work. | unknown | |
d13435 | train | You could send Orchestrator as an auxiliary apps when using AWS Device Farm.
If you're using the console, this is done during the Specify device state step under Install other apps
If you're using the CLI use auxiliaryApps flag https://docs.aws.amazon.com/cli/latest/reference/devicefarm/schedule-run.html
A: Short answer: Uploading the orchestrator seems to work, but you dont need it to get the tests run in separate processes.
Long answer: As Scott's answer said, you can upload and install the orchestrator to the device. You should upload android test services apk as well (test-services-1.4.0-alpha05.apk for example)
Also the Piotr's comment is correct. If you want to use the orchestrator, you should specify your own start command for tests like this: "adb shell "CLASSPATH=$(pm path androidx.test.services) exec app_process / androidx.test.services.shellexecutor.ShellMain am instrument ...". This can be done by using the custom evironment option from the device farm's start test wizard. More info can be found here: https://developer.android.com/training/testing/junit-runner#using-android-test-orchestrator
If you want to get the tests run separatedly, just use the default environment option, as it seems to isolate the tests by default in the aws farm. There's no need to use the orchestrator. Orchestrator is needed only, if you want to use your own custom test runners, or use custom parameters that needs to be passed to the tests. | unknown | |
d13436 | train | This is a trigger that your admin has set up. Based on the error, I surmise that they want you to set up your client's View to only include one project (they want to keep you from syncing down the entire world when you set up your new client).
To create a new client, run:
p4 set P4CLIENT=your_workspace_name
p4 client
and take a look at the form that pops up. The View field defines which part of the depot(s) your client will "see" and operate on. According to the error message, your admin wants you to restrict this to a single "project" -- I don't know what that means in this context (maybe it means just a single depot, or maybe a single folder in a particular depot?) so you might need to talk to your admin about it, or maybe browse around in the GUI and try to glean from context clues (i.e. names of directories) what that message is referring to.
Just to use a made-up example, if you have a few different depots your default ("loose") View might look like:
//depot_one/... //your_workspace_name/depot_one/...
//mumble/... //your_workspace_name/mumble/...
//widgets/... //your_workspace_name/widgets/...
and if you want to only map the project //mumble/core to your workspace root, you'd change that View to:
//mumble/core/... //your_workspace_name/... | unknown | |

d13444 | train | std::popcount returns the number of active bits in a value. It is able to call intrinsic functions, if available.
constexpr auto get_popcount(auto list) {
decltype(list) result;
std::transform(list.begin(), list.end(), result.begin(), [](auto x) {
return std::popcount(x);
});
return result;
}
int main() {
constexpr auto i12 = std::array{
0b10000010u, 0b00000000u, 0b11000000u, 0b00001010u,
0b00000010u, 0b00000011u, 0b00000000u, 0b00000010u};
static_assert(get_popcount(i12) == std::array{ 2u, 0u, 2u, 2u, 1u, 2u, 0u, 1u });
}
A: Can't test this right now but (I1 XOR I2) AND I1 should leave only the bits that you want to count, so:
constexpr auto get_popcount(auto i1, auto i2) {
std::vector<std::pair(int,int)> res;
std::transform (i1.begin(), i1.end(), i2.begin(), res.begin(), []
(auto x, auto y){
return std::tie(std::popcount((x^y)&x),std::popcount((x^y)&y));
});
return res;
}
Where the first item of the touple is the number of bits on I1 and the second on I2.
A: I'm dealing with a similar problem, where I have to count the
number of '1' bits from a run-time-determined range. Don't know how long your bit array is, but mine is millions to billions of bits.
For a very long bit arrays (say, millions of bits), you could build an auxiliary tree structure for each bit array. The root node counts all bits 0~N in the array, the left child node of root stores the partial sum of bits 0~N/2, the right child node store the partial sum of bits (N/2+1)~N, etc. etc. That way, when you want to count the number of '1' bits from an arbitrary range, you traverse the tree and add the partial sum values stored in appropriate nodes of the tree. The time complexity is O(log(N)). When your array is huge, this is going to be much more efficient than iterating over the entire array (complexity O(N)).
If your array is smaller, I would guess SSE/AVX instructions can result in higher throughput? Like Stack Danny has implied, intrinsic functions may already be the underlying implementation of popcount.
If you just use a for loop, GCC is able to vectorize your loop into SSE/AVX (e.g. if you got AVX2 on your CPU, add '-mavx2 -O3' to your compiler command). That works for summing elements of an integer array, but I never examined if looping on a bitarray can also result in vectorized code. https://gcc.gnu.org/projects/tree-ssa/vectorization.html
A: Use the AND operator for i1 and i2 to get only the intersecting bits. Then in a loop, SHIFT right checking each bit using the AND operator until the variable is zero.
Assuming the arrays are in packs of 4 bytes (unsigned long), this should work:
size_t getIntersecting(unsigned long* i1, unsigned long* i2, size_t nPacks) {
size_t result = 0;
unsigned long bitsec;
for (size_t i = 0; i < nPacks; i++)
{
bitsec = i1[i] & i2[i];
while (bitsec != 0) {
if (bitsec & 1) {
result++;
}
bitsec >>= 1;
}
}
return result;
}
I'm not at my workstation to test it. Generally it should count intersecting bits.
EDIT:
After reexamination of your question, try something like this.
// Define the global vectors
vector<unsigned long> vector1;
vector<unsigned long> vector2;
// Define the function
void getIntersecting(unsigned long* pi1, unsigned long* pi2, size_t nPacks) {
// Initialize the counters to 0
unsigned long i1cnt = 0;
unsigned long i2cnt = 0;
// Local storage variables
unsigned long i1, i2;
// Loop through the pointers using nPacks as the counter
for (size_t i = 0; i < nPacks; i++) {
// Get values from the pointers
i1 = pi1[i];
i2 = pi2[i];
// Perform the bitwise operations
unsigned long i4 = i1 & i2;
// Loop for each bit in the 4-byte pack
for (int ibit = 0; ibit < 32; ibit++) {
// Check the highest bit of i4
if (!(i4 & 0x80000000)) {
// Check the highest bit of i1
if (i1 & 0x80000000) {
i1cnt++;
}
// Check the highest bit of i2
if (i2 & 0x80000000) {
i2cnt++;
}
}
else {
// Push the counters to the global vectors
vector1.push_back(i1cnt);
vector2.push_back(i2cnt);
// Reset counters
i1cnt = 0;
i2cnt = 0;
}
// Shift i4, i1, and i2 left by 1 bit
i4 = i4 << 1;
i1 = i1 << 1;
i2 = i2 << 1;

d13445 | train | It definitely sounds like you're only listening on localhost, so add your IP address from eth0 (or whichever interface you're using).
Your config line:
interfaces = 127.0.0.1/8 192.168.0.0/24
is incorrect. 127.0.0.1/8 is a way to express both the IP and the subnet. 192.168.0.0/24 is a subnet declaration. Change the 192.168.0.0/24 to whatever your actual IP address is (/sbin/ifconfig) and restart samba.

I suppose the box is a pixmap inside a QLabel ( label->setPixmap(...) )
OR
Set the object name to something (the label), and then use the
QLabel#name { bottom-right-radius: 10px... }
In a stylesheet you load.

A: You can use QPainterPath for that :
QPainterPath path;
path.setFillRule( Qt::WindingFill );
path.addRoundedRect( QRect(50,50, 200, 100), 20, 20 );
path.addRect( QRect( 200, 50, 50, 50 ) ); // Top right corner not rounded
path.addRect( QRect( 50, 100, 50, 50 ) ); // Bottom left corner not rounded
painter.drawPath( path.simplified() ); // Only Top left & bottom right corner rounded
A: Also you can use arcTo() to create rounded corners.
Showcase:
Code:
// Position of shape
qreal x = 100.0;
qreal y = 100.0;
// Size of shape
qreal width = 300.0;
qreal height = 200.0;
// Radius of corners
qreal corner_radius = 30.0;
QPainterPath path;
path.moveTo(x + corner_radius, y);
path.arcTo(x, y, 2 * corner_radius, 2 * corner_radius, 90.0, 90.0);
path.lineTo(x, y + (height - 2 * corner_radius));
path.arcTo(x, y + (height - 2 * corner_radius), 2 * corner_radius, 2 * corner_radius, 180.0, 90.0);
path.lineTo(x + (width - 2 * corner_radius), y + height);
path.lineTo(x + (width - 2 * corner_radius), y);
path.lineTo(x + corner_radius, y);

A: You can separately draw polygon and pies to create rectangle with 2 rounded corners
Code:
// Position of shape
qreal x = 100;
qreal y = 100;
// Radius of corners
qreal border_radius = 30;
// Size of shape
qreal width = 300;
qreal height = 200;
QPolygonF myPolygon;
myPolygon << QPointF(x, y+border_radius) << QPointF(x+border_radius, y+border_radius)
<< QPointF(x+border_radius, y) << QPointF(x+width, y)
<< QPointF(x+width, y+height) << QPointF(x+border_radius, y+height)
<< QPointF(x+border_radius, y+height-border_radius)
<< QPointF(x, y+height-border_radius) << QPointF(x, y+border_radius);
QPainterPath myPath;
myPath.addPolygon(myPolygon);
QPainter painter(this);
painter.setRenderHints(QPainter::Antialiasing);
painter.setPen(Qt::NoPen);
QBrush myBrush(QColor(0, 0, 0), Qt::SolidPattern);
painter.setBrush(myBrush);
// Draw base polygon
painter.drawPath(myPath);
// Add rounded corners
painter.drawPie(x, y, 2*border_radius, 2*border_radius, 90*16, 90*16);
painter.drawPie(x, y+height-2*border_radius, 2*border_radius, 2*border_radius, 180*16, 90*16);
How does it look like:
Main polygon:
QPolygonF myPolygon;
myPolygon << QPointF(x, y+border_radius) << QPointF(x+border_radius, y+border_radius)
<< QPointF(x+border_radius, y) << QPointF(x+width, y)
<< QPointF(x+width, y+height) << QPointF(x+border_radius, y+height)
<< QPointF(x+border_radius, y+height-border_radius)
<< QPointF(x, y+height-border_radius) << QPointF(x, y+border_radius);
QPainterPath myPath;
myPath.addPolygon(myPolygon);
// Draw base polygon
painter.drawPath(myPath);
Corners:
// Add rounded corners
painter.drawPie(x, y, 2*border_radius, 2*border_radius, 90*16, 90*16);
painter.drawPie(x, y+height-2*border_radius, 2*border_radius, 2*border_radius, 180*16, 90*16);
A: To extend the answer of Romha Korev. Here an example of a box with only rounded top corners (top left, top right). The rectangles in the corners are calculated based on the main rectangle!
qreal left = 5;
qreal top = 10;
qreal width = 100;
qreal height = 20;
QRectF rect(left, top, width, height);
QPainterPath path;
path.setFillRule( Qt::WindingFill );
path.addRoundedRect(rect, 5, 5 );
qreal squareSize = height/2;
path.addRect( QRect( left, top+height-squareSize, squareSize, squareSize) ); // Bottom left
path.addRect( QRect( (left+width)-squareSize, top+height-squareSize, squareSize, squareSize) ); // Bottom right
painter->drawPath( path.simplified() ); // Draw box (only rounded at top) | unknown | |

d13453 | train | I really like this solution. By changing the 302 response on ajax requests to a 401 it allows you to setup your ajax on the client side to monitor any ajax request looking for a 401 and if it finds one to redirect to the login page. Very simple and effective.
Global.asax:
protected void Application_EndRequest()
{
if (Context.Response.StatusCode == 302 &&
Context.Request.Headers["X-Requested-With"] == "XMLHttpRequest")
{
Context.Response.Clear();
Context.Response.StatusCode = 401;
}
}
Client Side Code:
$(function () {
$.ajaxSetup({
statusCode: {
401: function () {
location.href = '/Logon.aspx?ReturnUrl=' + location.pathname;
}
}
});
});
A: try with cache: false cache option in jquery ajax:
$.ajax({
url: "test.html",
cache: false,
success: function(html){
$("#results").append(html);
}
});
---EDIT
Try with this in C# code :
protected void Page_Load(object sender, System.EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
...
}
A: A similar problem has been encountered before. Is the solution given in this question helpful?
A: This is the solution I've used in the past:
Server side:
When I'm checking to see if a session is still valid, I also keep an eye out for the "X-Requested-With" header, which should be "XMLHttpRequest" if you're using jQuery (NOTE: IE tends to return the header name in lower case, so watch for that as well). If the session has indeed expired and the header is present, instead of using an HTTP redirect, I respond with a simple JSON object like this:
{ "SESSION": "EXPIRED" }
Client side:
In my onload code, I use jQuery's ajaxComplete event to check all incoming request payloads for the session expired object. The code looks something like this:
$(window).ajaxComplete(function(ev, xmlhr, options){
try {
var json = $.parseJSON(xmlhr.responseText);
}
catch(e) {
console.log('Session OK');
return;
}
if ($.isPlainObject(json) && json.SESSION == 'EXPIRED') {
console.log('Session Expired');
//inform the user and window.location them somewhere else
return;
}
console.log('Session OK');
});
A: I'm pretty sure you will never get the 302 in the completed status of the XHR object. If a redirect occurs then the connection is still in process until you see the response from the login page (which should be 200, if it exists).
However, why do you need to see the 302? Surely if you are getting a redirect to login.php then simply getting the url (or parsing for content) of the returned response tells you they have been logged out?
An alternative, only if you want to know as soon as the session has expired (before they do some action), is to poll the server using setTimeout or similar to get information on the authentication status.
Good luck. | unknown | |

d13457 | train | The simplest way is to use Activity Recognition API http://developer.android.com/training/location/activity-recognition.html .
Or you could read raw data from sensors to recognize patterns. But eventually you'll come the same functionality. | unknown | |
d13458 | train | Since you are trying to edit the array elements and its size, I believe array_map() or array_filter() won't be a solution to this.
This is what I could come up with...
$jobs = [
'Director', 'Director of Photography', 'Cinematography',
'Cinematographer', 'Story', 'Short Story', 'Screenplay', 'Writer'
];
$crew = [];
foreach($tmdbApi as $key => $member) {
if($member['id'] == $id && in_array($member['job'], $jobs)) {
if(!isset($crew[$key])) {
$crew[$key] = $member;
} else {
$crew_jobs = explode(', ', $crew[$key]['job']);
if(!in_array($member['job'], $crew_jobs)) {
$crew_jobs[] = $member['job'];
}
$crew[$key]['job'] = implode(', ', $crew_jobs);
}
}
}
Hope this answers your question :)
A: You could nicely use Laravel's Collection in such a situation, which has a great number of methods which will help you in this case.
First, turn this array (the one you already filtered on jobs) to a Collection:
$collection = collect($crew);
Second, group this Collection by it's ids:
$collectionById = $collection->groupBy('id');
Now, the results are grouped by the id and transformed to a Collection in which the keys correspond to the id, and the value an array of 'matching' results. More info about it here.
Finally, just a easy script that iterates through all the results for each id and combines the job field:
$combinedJobCollection = $collectionById->map(function($item) {
// get the default object, in which all fields match
// all the other fields with same ID, except for 'job'
$transformedItem = $item->first();
// set the 'job' field according all the (unique) job
// values of this item, and implode with ', '
$transformedItem['job'] = $item->unique('job')->implode('job', ', ');
/* or, keep the jobs as an array, so blade can figure out how to output these
$transformedItem['job'] = $item->unique('job')->pluck('job');
*/
return $transformedItem;
})->values();
// values() makes sure keys are reordered (as groupBy sets the id
// as the key)
At this point, this Collection is returned:
Collection {#151 ▼
#items: array:4 [▼
0 => array:6 [▼
"credit_id" => "52fe49dd9251416c750d5e9d"
"department" => "Directing"
"id" => 139098
"job" => "Director, Story, Screenplay"
"name" => "Derek Cianfrance"
"profile_path" => "/zGhozVaRDCU5Tpu026X0al2lQN3.jpg"
]
1 => array:6 [▼
"credit_id" => "52fe49dd9251416c750d5edd"
"department" => "Writing"
"id" => 132973
"job" => "Story, Screenplay"
"name" => "Ben Coccio"
"profile_path" => null
]
2 => array:6 [▼
"credit_id" => "52fe49dd9251416c750d5eef"
"department" => "Writing"
"id" => 1076793
"job" => "Screenplay"
"name" => "Darius Marder"
"profile_path" => null
]
3 => array:6 [▼
"credit_id" => "52fe49de9251416c750d5f13"
"department" => "Camera"
"id" => 54926
"job" => "Director of Photography"
"name" => "Sean Bobbitt"
"profile_path" => null
]
]
}
Note: to use this Collection as an array, use:
$crew = $combinedJobCollection->toArray();
There are multiple ways to achieve this, for example: search the array for overlapping id's, but I think this is the easiest way to achieve this.

There seems to be differences between custom elements:
1) The ones that use their own shadow DOM ( "stand alone element", "autonomous element" ), and hence are forced to extend HTMLElement ( so not HTMLFormElement ), can be written in the <my-form> style inside the HTML.
2) For custom elements that do not extend HTMLElement, but try to extend other things, like a HTMLFormElement, it seems you need to use <form is="your-defined-name"></form>, ( "customized builtin element" )

d13463 | train | Goku, in apex, the best way to learn (you said yourself you're a beginner) is to write a lot of small apps in a dev environment that only perform one thing. That way you can isolate issues and study behavior in detail. I suggest you do the same for this switch item issue to figure out what the problem is. You have not provided enough information for anyone to answer it so users are giving you their best guesses.
So this is what I did. Create test table
create table so_test_with_switch (
so_test_with_switch_id number generated by default on null as identity
constraint so_test_with_switc_id_pk primary key,
name varchar2(255),
switchval number
);
Create a report and form in apex, change the form item for switchval page item (P32_SWITCHVAL) to "Switch" with custom settings: 1 for On and 0 for off. I tested and my form worked fine. The error message indicates that the value apex is getting does not match either 1 or 0 so it must get that value from somewhere else. In my case I added an after submit computation to set the value of P32_SWITCHVAL to 'Y'. Saved my changes, ran the form, clicked "Apply Changes" and I got the same error as you.
It is up to you to figure out where your page item is getting the other value from. Go through your page, investigate and debug. The key to finding the solution is in your code.

So the actual problem before was that the Nib was being loaded during tests. This solution prevents this. It just loads the application with a mocked application delegate whenever it detects a test run (By looking for the XCTest class).
I'm sure I will have to tweak this a bit more. Especially when a start with UI Testing. But for the moment it works. | unknown | |
d13468 | train | Use execSQL() for such SQL and not rawQuery().
rawQuery() just compiles the SQL but does not run it. You'd need to call one of the move...() methods on the returned Cursor to execute a step of the compiled SQL program.
execSQL() both compiles and runs the SQL program.
There's also possibly a syntax problem with your literals - use parameters i.e. ? placeholders in SQL and String[] bind arguments to be safe.

Try str() like above, it seems the data you got before hasn't clarifed the type of value that 'description' storged.
A: May be the API didn't match the description, so you can use ifelse to solve it. Just like this.
description = repo_dict['description']

description = 'No description provided'
plot_dict = {
'value': repo_dict['stargazers_count'],
'label': description,

Setup
First you must make sure that you have the package installed
To use mod_rewrite, you need to load the extension. Usually, this is done by inmporting the rewrite.so module in the apache2 global configuration (/etc/apache2/apache2.conf)
Usually all mod_rewrite instruction are written in the virtual host definition. (Say: /etc/apache2/site-available/000default)
Usage
First step
To enable rewrite for one site, you have to ask for it with :
RewriteEngine On
Then you can begin to write rules. The basic you need to write rules is describe by the following diagram :
(See also : How does url rewrite works?)
To help me understand how it works, always consider it from the server side (not client side).
You receive an URL from the client. This URL has a certain format that you had defined. (E.g. http://blog.com/article/myarticle-about-a-certain-topic). But apache can't understand this by himself, so we need to help him. We know that the controller is page.php and can look up article by name.
Getting information
So now we forge a regex to extract information from the URL. All regex are matched against what is following your domain name (here : article/myarticle-about-a-certain-topic without the first / -- It can be written though on recent version of rewrite)
Here we need the article's name: ^article/(.*)$ will do the job of matching URL against article/<something> and capturing <something> into $1. (For characters meaning, I advise you to look a tutorial on regex. Here ^ is beginning of the string, invisible position after the .com/, and $ the end of the URL)
So now we need to informe apache that this URL means http://myblog.com/page.php?article=myarticle-about-a-certain-topic
This is achieved by using a RewriteRule
RewriteRule ^article/(.*)$ page.php?article=$1
Restricting to conditions
To go a bit on advance topics, you may want to apply this rule only if the article name is fetch by GET method. To do this, you can include a RewriteCond like
RewriteCond %{REQUEST_METHOD} GET
It goes BEFORE a RewriteRule in the file but is tested AFTER it.
Flags
If you are making lot of redirection/rewrite, you will have to understand flags
The most used are [L] and [R]. A little explanation on those :
*
*[R] ask for redirection, it can be tuned like [R=302] where 302 is a redirection status number of the HTTP protocol. This will force the client to make a new request with the rewritten URL. Therefore he will see the rewritten URL in his address bar.
*[L] forces apache to stop treating rules. Be advise that it does mean that the current incoming URL will stop being modified, but the rewritten URL WILL go again through the process of rewriting. Keep this in mind if you want to avoid loops.
Conclusion
So you end up with the following block of instructions
RewriteEngine On
RewriteCond %{REQUEST_METHOD} GET
RewriteRule ^article/(.*)$ page.php?article=$1

d13474 | train | In PHP you can use the file_get_contents() function to grab files over the internet.
$html = file_get_contents('https://raw.github.com/USER/PROJECT/master/file.html');

Your pages will be slower if you do this, though. Setting up a cronjob that downloads the file to your server periodically, and then serving it from your server, is a much better idea.
A: $url = "http://www.example.com"; //write your raw.github.com URL

d13477 | train | Your _setDomainName usage is correct and sufficient.
But its value is never send to Analytics : you must use it BEFORE _trackPageview.
Then _addIgnoredRef is not useful anymore.
A: Move the _trackPageview calls after the _setDomainName and _addIgnoredRef calls.
_setDomainName sets the domain for the GA cookies, which get set during _trackPageview. By having _setDomainName after _trackPageview, the default cookie domain is used, resulting in two different sets of cookies, and the data not transferring between domain/subdomain. | unknown | |
d13478 | train | Assuming the address points to int, you may do:
cout << "Value is : " << *reinterpret_cast<int*>(0xfee2200);
as literal 0xfee2200 is an interger type whereas you expected a pointer.
A: You have to decide as what type of data you want to interpret the memory content and cast it accordingly:
const char* tmp = "foofoo"; // Valid ptr for this example
const void* address = tmp; // Set to your address
const int* i = reinterpret_cast<const int*>(address);
const unsigned short* us = reinterpret_cast<const unsigned short*>(address);
const char* c = reinterpret_cast<const char*>(address);
std::cout << "i: " << (*i)

A: Short answer: /HTTP[^-]*-([\d\s]+)/
then, call split on the result.
This regexp translates to:
"HTTP", followed by any number of non-hyphen characters, followed by a hyphen, followed by the largest string consisting only of digits and spaces. | unknown | |
d13480 | train | Your problem is one of message framing. The Available property only reports the bytes that have arrived so far - not the complete HTTP request or response.
If this is just a learning exercise, then I recommend using another protocol. HTTP has one of the most complex message framing systems of any protocol.
If this is intended for production, then you'll have to implement (at least partial) HTTP parsing to handle the message framing, and I also recommend a change to asynchronous socket methods rather than synchronous. A better solution is to just implement a web application that uses WebRequest to handle client requests. | unknown | |
d13481 | train | First you must convert text on textbox to int or any number type
Simple way :

{
int numberA = int.Parse(textBox1.Text.Trim());
int numberB = int.Parse(textBox2.Text.Trim());
var result = numberA + numberB;
textBox3.Text = result.ToString();
}
Safe way :
private void EqualsButton_Click(object sender, EventArgs e)
{
if (!int.TryParse(textBox1.Text.Trim(), out int numberA))
numberA = 0;
if (!int.TryParse(textBox2.Text.Trim(), out int numberB))
numberB = 0;
var result = numberA + numberB;
textBox3.Text = result.ToString();
}
A: private void EqualsButton_Click(object sender, EventArgs e)
{
var resultA=0;
var resultB=0;
if(!string.IsNullOrEmpty(InputTextBoxA.Text))
resultA=Convert.ToInt32(InputTextBoxA.Text);
if(!string.IsNullOrEmpty(InputTextBoxB.Text))
resultB=Convert.ToInt32(InputTextBoxB.Text);
OutputTextBox.Text = resultA+ resultB ;
}
A: Don't listen to anyone. Do this
txtResult.Text = string.Empty;
if (!decimal.TryParse(txt1.Text.Trim(), out decimal v1))
{
MessageBox.Show("Bad value in txt1");
return;
}
if (!decimal.TryParse(txt2.Text.Trim(), out decimal v2))
{
MessageBox.Show("Bad value in txt2");
return;
}
txtResult.Text = (v1 + v2).ToString();
A: You can change into this
private void EqualsButton_Click(object sender, EventArgs e)
{
try
{
OutputTextBox.Text = ($"{ Convert.ToInt32(InputTextBoxA.Text.Trim() == "" ? "0" : InputTextBoxA.Text) + Convert.ToInt32(InputTextBoxB.Text.Trim() == "" ? "0" : InputTextBoxB.Text)}");
}
catch(exception ex)
{
MessageBox.Show("Enter Valid number")'
}
}
A: You need to convert text fields to int and after for the answer back to the text.
If you did not enter a value, then there "" is considered as 0 when adding.
private void EqualsButton_Click(object sender, EventArgs e)
{
OutputTextBox.Text = Convert.ToString(
Convert.ToInt32(InputTextBoxA.Text == "" ? "0" : InputTextBoxA.Text)
+ Convert.ToInt32(InputTextBoxB.Text == "" ? "0" : InputTextBoxB.Text));

d13482 | train | Should be hardware problem. When StageVideo is not available on particular device stage.stageVideos property is empty, so to make sure you should make check like this.
var stageVideo:StageVideo;
if ( stage.stageVideos.length >= 1 ) {
stageVideo = stage.stageVideos[0];
}
or register StageVideoAvailabilityEvent on stage
stage.addEventListener(StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY, stageVideoChange);
private function stageVideoChange(e:StageVideoAvailabilityEvent):void
{
if(e.availability == AVAILABLE)
{
// (stage.stageVideos.length >= 1) is TRUE so we can use stageVideo[0]
}
else
{
// StageVideo become unavailable for example after going from fullscreen
// back to wmode=normal, wmode=opaque, or wmode=transparent
}
}
Of course second approach is more acceptable because you are notified every time StageVideo becomes available or negative. Note if stage video is available at the moment of registering Listener on StageVideoAvailabilityEvent then listener function (stageVideoChange) is called immediately.
A: Turns out Starling runs on Stage3D on TOP of the actual flash display stage. So in order to do this, you need to hide the Starling Stage3D first:
Starling.current.stage3D.visible = false
Then you can access and show...etc stageVideos and add to the flash display stage:
_stageVideo = Starling.current.nativeStage.stageVideos[0];
So basically, the native flash display stage is on the Starling.current.nativeStage property, however, can not be visible unless you first hide the Starling.current.stage3D FIRST.
Thanks for the responses! Hope this helps anyone else with the same problem. | unknown | |

This regex matches the leading < or </ only if it is not followed by one of the tag names you want to keep p, li, br, b (followed by a space or closing >, so that it doesn't think <pre> is <p>).
Then it matches everything up to the closing >.
A: See this answer.
That said, square brackets [] match on single characters, not words - for more information on what yours is doing, see the bottom of this answer. Instead, you would need to use parentheses (?:p|li|br|b) to match words - the ?: is used to avoid capturing. Also, the parentheses would occur outside of the square brackets.
Since you're using a negative match you may wish to look into lookarounds; specifically, the section on Positive and Negative Lookbehind.
[^\>,p,li,br,b] translates to not > and not , and not p and not , and not l and not i and not , and not b and not r and not , and not b. | unknown | |

d13498 | train | What you are describing is a basic function in almost all AM software implementing OIDC, there is no such a thing as log in to clientA, the users always log in to the IDP, i.e. Keycloak.
Clients dont have sessions by default, keycloak does, and clients use keycloak session in thier OIDC flow. For example if you are already authenticated to keycloak, and you tried to do OIDC flow with ClientA or ClientB, you wont be prompted to enter username/password, keycloak will use the existing session.
So if you want to have different session for the same user, then you have to create your own session, for example if your clients are using apache, you can use apache oidc module to create a local session ( which will be your ClientA session), as for keycloak session, you cant have two sessions, but you can have one keycloak session for the two clients and two apache session for each clients. | unknown | |

}
A: Use TouchyWebView.java
public class TouchyWebView extends WebView {
public TouchyWebView(Context context) {
super(context);
}
public TouchyWebView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TouchyWebView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public boolean onTouchEvent(MotionEvent event){
requestDisallowInterceptTouchEvent(true);
return super.onTouchEvent(event);
}
}
In layout file:
<yourclasapath.TouchyWebView
android:id="@+id/description_web"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
A: Our solution uses a Javascript callback through the Javascript Interface. Every time a part of the UI that is scrollable inside the WebView is touched a listener is called through java script and this listener calls requestDisallowInterceptTouchEvent on the WebViews parent.
This is not optimal but the nicest solution found at the moment. If the user scrolls very fast the layer in the WebView won't scroll but at a normal scroll rate it works fine. | unknown | |
d13500 | train | Finally I had to resign not to use alert() and confirm() anymore.
I just made two simple functions that replace the standard ones:
function async_alert(message) {
$("body").append("<div class='alert-box'>\
<div class='alert-surface'>\
<h2>Alert</h2></header>\
<p>" + message + "</p>\
<button type='button' class='alert-remove'>OK</button>\
</div>\
<div class='alert-backdrop'></div>\
</div>");
$(".alert-remove").off("click").on("click", function() { $(".alert-box").remove(); });
}
function async_confirm(message, onAcceptFunction) {
$("body").append("<div class='confirm-box'>\
<div class='confirm-surface'>\
<h2>Confirm</h2>\
<p>" + message + "</p>\
<button type='button' class='confirm-remove'>Cancel</button>\
<button type='button' class='confirm-accept'>OK</button>\
</div>\
<div class='confirm-backdrop'></div>\
</div>");
$(".confirm-remove").off("click").on("click", function() { $(".confirm-box").remove(); });
$(".confirm-accept").off("click").on("click", onAcceptFunction);
}
You should adjust your styles achieving that .alert-box div covers view-port entirey and .alert-surface div becomes a centered rectangle containing informations. E.g.:
.alert-box, .confirm-box {
position: fixed;
top: 0;
left: 0;
align-items: center;
justify-content: center;
width: 100%;
height: 100%;
z-index: 100000;
display: flex;
align-items: flex-start;
}
.alert-surface, .confirm-surface {
opacity: 1;
visibility: visible;
box-shadow: 0 11px 15px -7px rgba(0,0,0,.2), 0 24px 38px 3px rgba(0,0,0,.14), 0 9px 46px 8px rgba(0,0,0,.12);
background-color: #fff;
display: inline-flex;
flex-direction: column;
width: calc(100% - 30px);
max-width: 865px;
transform: translateY(50px) scale(.8);
border-radius: 2px;
}
.alert-backdrop, .confirm-backdrop {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0,0,0,.87);
opacity: .3;
z-index: -1;
}
You can use async_alert() just as the original alert() function, but keep in mind that this newly defined function is just asynchronous while the other is synchronous (so it doesn't stop your runtime javascript execution waiting your click).
You can also replace the standard browser alert function:
window.alert = async_alert;
To use async_confirm() function you should slightly change your code from:
if(confirm("Do something?") {
console.log("I'm doing something");
}
to:
async_confirm("Do something?", function() {
console.log("I'm doing something");
});
Once again, pay attention that async_confirm() il an asynchronous function compared to the standard confirm(). | unknown |
