d4901 | train | How about: diff -I '^time.*' file1 file2?
Please note it doesn't always work as expected as per diffutils manual:
However, -I only ignores the insertion or deletion of lines that contain the regular expression if every changed line in the hunk (every insertion and every deletion) matches the regular expression.
In other words, for each non-ignorable change, diff prints the complete set of changes in its vicinity, including the ignorable ones. You can specify more than one regular expression for lines to ignore by using more than one -I option. diff tries to match each line against each regular expression, starting with the last one given.
A: What about this?
diff <(grep -v '^time:' file1) <(grep -v '^time:' file2) | unknown | |

d4904 | train | You are getting this error because you are not using any observable list inside your ListView.builder.
But before that you should convert your StatefullWidget to a StatelessWidget because in GetX, we don't need any StatefullWidget.
You can try the following code.
Controller

final Rx<List<Stories>> _stories = Rx<List<Stories>>([]);
List<Stories> currUserstories = [];
RxBool isLoading = false.obs;
@override
void onInit() {

Future<List<Stories>> getActiveStories() async {
isLoading.value = true;

Map<String, Object> params = {'apikey': apiKey, 'userid': "8"};
await http.post(url, body: params).then((value) {
StoriesResponse storiesResponse = storiesResponseFromJson(value.body);
_stories.value = storiesResponse.stories;
_stories.value =

currUserstories = _stories.value[0];
}).onError((error, stackTrace) {
debugPrint(

});
isLoading.value = false;
return _stories.value;

itemBuilder: (ctx, index) => ActiveStoriesWidget(
story: _feedsController.currUserstories[index]),
itemCount: _feedsController.currUserstories.length,
),
)),
],
);
}
}
You might have to tweak the code a bit but the core concept it you should do all your work inside the controller and only fetch the data in view file.
Also, you should only use the lifecycle which controller provides. Eg. onInit instead of initState.
If this dosen't work, try to modify your controller file such that you get the value in the list as you want in the controller file itself and you the list which was preseneted in controller in your view file.

d4905 | train | This appears to be to do with the loop inside your move function. You call it with the parameter m representing the lengh of the ball array - but the function checkCollisionPlayer which is called within that can remove a ball from the array if there is a collision. This means that the array is now shorter, so whenever you try to access a property on ball[m-1] later in the loop, as you will, you'll get this error.
I'm sure there are lots of different ways to fix this. The easiest I can think of (which I have successfully used myself in making a browser game) is to, instead of directly deleting the balls from the array upon collision, set a property on them to mark them as "deleted". Then add a "cleanup" function onto the end of the loop to filter the array into only those that are not marked as deleted. This ensures that every object you are looping over actually exists, while still changing the length dynamically to reflect the game state.

d4915 | train | I found a solution for this, though is not the most elegant. I couldn't find a way to make a predicate to work as the one I had in UI Automation, so I used a couple of for loops to check the value of the cell labels.
NSPredicate *enabledCellsPredicate = [NSPredicate predicateWithFormat:@"enabled == true "];
XCUIElementQuery *enabledCellsQuery = [classScheduleTableView.cells matchingPredicate:enabledCellsPredicate];
int cellCount = enabledCellsQuery.count;
for (int i = 0; i < cellCount; i++) {
XCUIElement *cellElement = [enabledCellsQuery elementBoundByIndex:i];
XCUIElementQuery *cellStaticTextsQuery = cellElement.staticTexts;
int textCount = cellStaticTextsQuery.count;
BOOL foundNoClasses = NO;
for (int j = 0; j < textCount; j++) {
XCUIElement *textElement = [cellStaticTextsQuery elementBoundByIndex:j];
if (textElement.value && [textElement.value rangeOfString:NSLocalizedString(@"No classes", nil) options:NSCaseInsensitiveSearch].location != NSNotFound) {
foundNoClasses = YES;
break;
}
}
if (foundNoClasses == NO) {
[cellElement tap];
break;
}
}
Thanks @joe-masilotti for your help anyway.
A: I don't believe your exact predicate is possible with UI Testing.
UI Testings vs UI Automation
Matching predicates with UI Testing (UIT) behaves a little differently than UI Automation (UIA) did. UIA had more access to the actual UIKit elements. UIT is a more black-box approach, only being able to interact with elements via the accessibility APIs.
NOT Predicate
Breaking down your query I'm assuming the second part is trying to find the first cell not titled 'No classes'. First, let's just match staticTexts.
let predicate = NSPredicate(format: "NOT label BEGINSWITH 'No classes'")
let firstCell = app.staticTexts.elementMatchingPredicate(predicate)
XCTAssert(firstCell.exists)
firstCell.tap() // UI Testing Failure: Multiple matches found
As noted in the comment, trying to tap the "first" cell raises an exception. This is because there is more than one match for a text label that starts with "No classes".
NONE Predicate
Using the NONE operator of NSPredicate leads us down a different path.
let predicate = NSPredicate(format: "NONE label BEGINSWITH 'No classes'")
let firstCell = app.staticTexts.elementMatchingPredicate(predicate)
XCTAssert(firstCell.exists)// XCTAssertTrue failed: throwing "The left hand side for an ALL or ANY operator must be either an NSArray or an NSSet." -
This approach can't even find the cell. This is because the elementMatchingPredicate() expects the predict to return a single instance, not an array or set. I couldn't figure out how to make the query select the first element. And once you get an XCUIElement there are no ways to farther restrict it.
Different Approach
That said I suggest you take a slightly different approach for your test. If your tests are deterministic, and they should be, just tap the first known cell. This means you don't have to worry about ambiguous matchers nor chaining predicates.
let firstCell = app.staticTexts["Biology"]
XCTAssert(firstCell.exists)
firstCell.tap() | unknown | |

d4919 | train | I'd use http://json2csharp.com/ (or any other json to c# parser) and then use C# objects (it's just easier for me)
This would look like that for this case:
namespace jsonTests
{
public class DeviceTypeWithResponseTypeMapper
{
public string DeviceType { get; set; }
public List<string> ResponseTypes { get; set; }
}
public class RootObject
{
public List<DeviceTypeWithResponseTypeMapper> DeviceTypeWithResponseTypeMapper { get; set; }
}
}
and the use it like that in code:
var rootob = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(str);
var thoseThatHaveNotUsed = rootob.DeviceTypeWithResponseTypeMapper.Where(dtwrtm =>
dtwrtm.ResponseTypes.Any(rt => rt == "NotUsed"));
foreach (var one in thoseThatHaveNotUsed)
{
Console.WriteLine(one.DeviceType);
}
this code lists all the Device types that have "NotUsed" among the responses.
version 2 (extending your code) would look like that, i believe:
static void Main(string[] args)
{
var json = str; // below json is stored in file jsonFile
var jObject = JObject.Parse(json);
JArray ZoneMappingArray = (JArray)jObject["DeviceTypeWithResponseTypeMapper"];
string strDeviceType = "Police";
string strResponseType = "NotUsed";
var JToken = ZoneMappingArray.Where(obj => obj["DeviceType"].Value<string>() == strDeviceType).ToList();
var isrespTypeThere = JToken[0].Last().Values().Any(x => x.Value<string>() == strResponseType);
Console.WriteLine($"Does {strDeviceType} have response type with value {strResponseType}? {yesorno(isrespTypeThere)}");
}
private static object yesorno(bool isrespTypeThere)
{
if (isrespTypeThere)
{
return "yes!";
}
else
{
return "no :(";
}
}
result:
and if you'd like to list all devices that have response type equal to wanted you can use this code:
var allWithResponseType = ZoneMappingArray.Where(jt => jt.Last().Values().Any(x => x.Value<string>() == strResponseType));
foreach (var item in allWithResponseType)
{
Console.WriteLine(item["DeviceType"].Value<string>());

d4925 | train | how could a child class know (without taking a look at base class implementation) which order (or option) is being expected by the parent class?
There is no way to "know" this when you are subclassing and overriding a method. Proper documentation is really the only option here.
Is there a way in which parent class could enforce one of the three alternates to all the deriving classes?
The only option here is to avoid the issue. Instead of allowing the subclass to override the method, it can be declared non-virtual, and call a virtual method in the appropriate place. For example, if you want to enforce that subclasses "call your version first", you could do:
public class BaseClass {
public void Method() // Non-virtual
{
// Do required work
// Call virtual method now...
this.OnMethod();
}
protected virtual void OnMethod()
{ // Do nothing
}
}
The subclasses can then "override" OnMethod, and provide functionality that happens after "method"'s work.
The reason this is required is that virtual methods are designed to allow a subclass to completely replace the implementation of the parent class. This is done on purpose. If you want to prevent this, it's better to make the method non-virtual.
A: This is why I feel virtual methods are dangerous when you ship them in a library. The truth is you never really know without looking at the base class, sometimes you have to fire up reflektor, read documentation or approach it with trial and error.
When writing code myself I've always tired to follow the rule that says:
Derived classes that override the protected virtual method are not required to call the base class implementation. The base class must continue to work correctly even if its implementation is not called.
This is taken from http://msdn.microsoft.com/en-us/library/ms229011.aspx, however this is for Event design though I believe I read this in the Framework Design Guidelines book (http://www.amazon.com/Framework-Design-Guidelines-Conventions-Libraries/dp/0321246756).
However, this is obviously not true, ASP.NET web forms for example require a base call on Page_Load.
So, long and short, it varies and unfortunately there is no instant way of knowing. If I'm in doubt I will omit the call initially.
A: The short answer is no. You can't enforce in what order the child calls the base method, or if it calls it at all.
Technically this information should be included in the base object's documentation. If you absolutely must have some code run before or after the child class' code than you can do the following:
1) Create a non-virtual function in the base class. Let's call it MyFunction
2) Create a protected virtual function in the base class. Let's call it _MyFunction
3) Have deriving classes extend the _MyFunction method.
4) Have MyFunction call _MyFunction and run the code it needs to run before or after calling it.
This method is ugly and would require a lot of extra code, so I recommend just putting a notice in the documentation.
A: The requirements of the base class should be documented by the library designer.
This issue is the reason why some libraries contain mainly sealed classes. | unknown | |

@Html.PasswordFor(

Model.UserName != null
? new { required = "This field is required" }

or
pName = driver.find_element_by_css_selector(".xxxx").get_attribute("href")
print(pName)
A: div.xxxx a
first, check if this CSS_SELECTOR is representing the desired element.
Steps to check:
Press F12 in Chrome -> go to element section -> do a CTRL + F -> then paste the css and see, if your desired element is getting highlighted with 1/1 matching node.
If yes, then use explicit waits:
wait = WebDriverWait(driver, 20)
print(wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.xxxx a"))).get_attribute('href'))
Imports:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
A: The value of the href attribute i.e. aaaaa.pdf is within the <a> tag which is the only descendant of the <div> tag.
Solution
To print the value of the href attribute you can use either of the following locator strategies:
*
*Using css_selector:
print(driver.find_element(By.CSS_SELECTOR, "div.xxxx > a").get_attribute("href"))
*Using xpath:
print(driver.find_element(By.XPATH, "//div[@class='xxxx']/a").get_attribute("href"))
To extract the value ideally you have to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:
*
*Using CSS_SELECTOR:
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.xxxx > a"))).get_attribute("href"))
*Using XPATH:
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='xxxx']/a"))).get_attribute("href"))
*Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By

d4932 | train | Where do you set the todo? A put request replaces the current values with new ones. If you only set the description property but leave the todo out, it will overwrite it with an empty string, clearing any data you had in there. Either set the old value of the todo before making your put request or use a patch instead. A patch only affect certain selected values instead of everything. Anyway, it's still very possible to do this with a put instead.
Try creating a useEffect where you set your todo to state.
Something like this:
const todoVar = description.find((desc)=> desc.id === todo.id);
useEffect(()=>{
if(todoVar){
setDescription(description.todo)
}
},[todoVar, setDescription])
Basically, you want to set the todo value from your database to it's original value before making your PUT request. This way it won't be empty/null. | unknown | |

d4935 | train | These are objects that represent the same underlying entity, namely an HTTP cookie as defined by the RFC. Both "do" the same thing, representing a cookie header in an HTTP response (a request cookie is a name=value pair only, whereas response cookies can have several additional attributes as described in the RFC). Where you use one vs the other is simply a matter of what you are coding. If you are writing a JAX-RS provider, then the JAX-RS apis will use javax.ws.core.Cookie. If you are writing an HttpServlet, then you use the javax.servlet.http.Cookie. JAX-RS implementations will also allow you to use context injection so that you can have direct access to the HttpServlet objects within your JAX-RS service provider
A: javax.servlet.http.Cookie is created and placed on the HTTP response object with the addCookie method.
Instead, the description for javax.ws.core.Cookie reads:
Represents the value of a HTTP cookie, transferred in a request
… so you'd expect the getCookies method on the HTTP request object to return an array of that type of cookies, but no, it returns an array of javax.servlet.http.Cookie. Apparently javax.ws.core.Cookie is used by some methods in the javax.ws.rs packages. So you use javax.ws.core.Cookie with jax-rs web services and javax.servlet.http.Cookie with HttpServlets and their request / response objects. | unknown | |

d4941 | train | First, web APIs can not be called as script source. The output from a web API is the data as a string. Because the web API does not know (and doesn't want to assume) how the data is being called, it just dumps it. That way a CURL request can handle it just as well as an AJAX. It is up to you to determine how best to request the data for your needs.
The blogger API for comments is very well handled. Check it out.

d4943 | train | by:
account.UserID = userid
I assume you meant:
account.UserID = user.user_id()
The user id is a string, not a key, so you can't use a KeyProperty here. In fact, AFAIK, User objects as returned from users.get_current_user() don't have a key (at least not one that is documented) since they aren't datastore entries. There is an ndb.UserProperty, but I don't think it's use is generally encouraged.
What performance reasons are you referring to?
A: I think what you want is something like this UserAccounts(id=user_id), this way the user_id is the key. With this approach you can remove the userid field from the model definition | unknown | |

d4948 | train | how can I call specific method of portlet.java class on ajax call?
I think we can't have two different versions of serveResource methods like we do for action methods atleast not with the default implementation.
If you want different methods you would have to go the Spring MVC (@ResourceMapping) way to have that.
Still, you can define different logic in your serveResource method using the resourceId as follows (a full example):
In the JSP:
<portlet:resourceURL var="myResourceURL" id="myResourceID01" />
In the portlet class the serveResource method will contain the following code:
String resourceID = request.getResourceID();
if(resoureID.equals("myResourceID01")) {
// do myResourceID01 specific logic
} else {
// else do whatever you want
}
Please keep in mind [Important]
In a portlet you should not use <html>, <head>, <body> tags since portlets generate fragment of the page and not the whole page. Even if it is allowed your resultant page will not be well-formed and will behave differently on different browsers. And moreover the javascript which modifies DOM element will be totally useless.
Edit after this comment:
You can also use ajax with action methods:
People use <portlet:actionURL> with ajax generally for <form>-POST.
For this the actionURL is generated in a slightly different way in your jsp like this:
<portlet:actionURL name="ajax_AddAdvertise" var="addToDo" windowState="<%= LiferayWindowState.EXCLUSIVE.toString()%>">
</portlet:actionURL>
And in your portlet you can have (as in the question):
@ProcessAction(name = "ajax_AddAdvertise")
public void ajax_AddAdvertise(ActionRequest request, ActionResponse response) {
// ... your code

d4950 | train | In this case, in main(),
Node *root;
Why do you need to use a "double" pointer ( Node ** ) in functions that alter root is because root value as to be set in these functions.
For instance, say you want to allocate a Node and set it into root.
If you do the following
void alloc_root(Node *root) {
root = malloc(sizeof (Node));
// root is a function parameter and has nothing to do
// with the 'main' root
}
...
// then in main
alloc_root( root );
// here main's root is not set
Using a pointer to pointer (that you call "double pointer")
void alloc_root(Node **root) {
*root = malloc(sizeof (Node)); // note the *
}
...
// then in main
allow_root( &root );
// here main's root is set
The confusion comes probably from the Node *root in main, root being a pointer to a Node. How would you set an integer int i; in a function f? You would use f(&i) to call the function f(int *p) { *p = 31415; } to set i to the value 31415.
Consider root to be a variable that contains an address to a Node, and to set its value in a function you have to pass &root. root being a Node *, that makes another *, like func(Node **p). | unknown | |

d4955 | train | You are describing what Numpy calls a Generalized Universal FUNCtion, or gufunc. As it name suggests, it is an extension of ufuncs. You probably want to start by reading these two pages:
*
*Writing your own ufunc
*Building a ufunc from scratch
The second example uses Cython and has some material on gufuncs. To fully go down the gufunc road, you will need to read the corresponding section in the numpy C API documentation:
*
*Generalized Universal Function API
I do not know of any example of gufuncs being coded in Cython, although it shouldn't be too hard to do following the examples above. If you want to look at gufuncs coded in C, you can take a look at the source code for np.linalg here, although that can be a daunting experience. A while back I bored my local Python User Group to death giving a talk on extending numpy with C, which was mostly about writing gufuncs in C, the slides of that talk and a sample Python module providing a new gufunc can be found here.
A: If you want to stick with nditer, here's a way using your example dimensions. It's pure Python here, but shouldn't be hard to implement with cython (though it still has the tuple iterator). I'm borrowing ideas from ndindex as described in shallow iteration with nditer
The idea is to find the common broadcasting shape, sz, and construct a multi_index iterator over it.
I'm using as_strided to expand X and Y to usable views, and passing the appropriate vectors (actually (1,n) arrays) to the f(x,y) function.
import numpy as np
from numpy.lib.stride_tricks import as_strided
def f(x,y):
# sample that takes (10,) and (3,) arrays, and returns (10,) array
assert x.shape==(1,10), x.shape
assert y.shape==(1,3), y.shape
z = x*10 + y.mean()
return z
def brdcast(X, X1):
# broadcast X to shape of X1 (keep last dim of X)
# modeled on np.broadcast_arrays
shape = X1.shape + (X.shape[-1],)
strides = X1.strides + (X.strides[-1],)
X1 = as_strided(X, shape=shape, strides=strides)
return X1
def F(X, Y):
X1, Y1 = np.broadcast_arrays(X[...,0], Y[...,0])
Z = np.zeros(X1.shape + (10,))
it = np.nditer(X1, flags=['multi_index'])
X1 = brdcast(X, X1)
Y1 = brdcast(Y, Y1)
while not it.finished:
I = it.multi_index + (None,)
Z[I] = f(X1[I], Y1[I])
it.iternext()
return Z
sx = (2,3) # works with (2,1)
sy = (1,3)
# X, Y = np.ones(sx+(10,)), np.ones(sy+(3,))
X = np.repeat(np.arange(np.prod(sx)).reshape(sx)[...,None], 10, axis=-1)
Y = np.repeat(np.arange(np.prod(sy)).reshape(sy)[...,None], 3, axis=-1)
Z = F(X,Y)

A: I do not need a bazooka to kill a mouse. The answer is very simple.
bind a javascript function to the onclick of the button, and in that function, retrieve the value of the input field by its id, then assemble URL with the parameters and navigate away from within the javascript function.
JSF code (assume they are inside a form with myForm as its id):
<p:inputText id="myInput" style="width:75px;" />
<p:commandButton id="myButton" value="Ir" onclick="navega();" title="Ir" ajax="false" proces="@none" />
Javascript script, declared on a separate file or later on in the xhtml document:
function navega() {
var submittedInputValue = $('#myForm\\:myInput').val();
window.location.href = "/site/mypage.xhtml?param1=whatever&id=" + submittedInputValue ;
}
Take note of the prepend id (myForm:myInput), of using \\ to escape the : in jQuery, and using & instead of & in the xhtml so its not treated as an entity.
Note: probably not all of those commandButton attributes are required, feel free to edit this answer and remove the useless ones.
EDIT: removed the submit and changed process to @none on the command button. | unknown | |
d4960 | train | Well you should prefer to use Google Cloud Messaging GCM for push notifications rather than using 3rd Parties like Parse etc. GCM is super fast and i am using in all my apps which are live.

http://developer.android.com/google/gcm/index.html

A: I am aware about the parse notification.I am also having same problem,but the problem is because of the Wifi.
It means when you send an parse notification from panel it would take some time to deliver because of wifi is enable on your mobile.
So go with your mobile 3G connection it works within less time.
A: Turns out, Parse has a GCM handler, and it also needs to be added to the manifest. Otherwise Parse uses its own service, which can be very slow. Enabling GCM, I now have the notifications arriving in under 20 seconds. | unknown | |

d4963 | train | After numerous searches for ways to utilize OpenSSL from Java I have ended up with JNA wrapper implementation, which, suprisingly, appeared to be pretty simple.
Fortunately, OpenSSL is designed in such way that in vast majority of use-cases we do not need to exactly know the type of the value, returned from the call to OpenSSL function (e.g. OpenSSL does not require to call any methods from structures or work with structure fields directly) so there is no need in huge and complex wrappings for OpenSSL's data types.
Most of OpenSSL's functions operate with pointers, which may be wrapped into an instance of com.sun.jna.Pointer class, which is equivalent to casting to void* in terms of C, and the callee will determine the correct type and de-reference the given pointer correctly.
Here is a small code example of how to load ssleay32.dll, initialize the library and create a context:
1) Define the interface to ssleay32.dll library (functions list may be obtained from OpenSSL GitHub repo or by studying the export section of the dll):
import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.Pointer;
public interface OpenSSLLib extends Library {
public OpenSSLLib INSTANCE = (OpenSSLLib) Native.loadLibrary("ssleay32",
OpenSSLLib.class);
// Non-re-enterable! Should be called once per a thread (process).
public void SSL_library_init();
public void SSL_load_error_strings();
// Supported context methods.
public Pointer TLSv1_method();
...
// Context-related methods.
public Pointer SSL_CTX_new(Pointer method);
public void SSL_CTX_free(Pointer context);
public int SSL_CTX_use_PrivateKey_file(Pointer context, String filePath, int type);
public int SSL_CTX_use_certificate_file(Pointer context, String filePath, int type);
public int SSL_CTX_check_private_key(Pointer context);
public int SSL_CTX_ctrl(Pointer context, int cmd, int larg, Pointer arg);
public void SSL_CTX_set_verify(Pointer context, int mode, Pointer verifyCallback);
public int SSL_CTX_set_cipher_list(Pointer context, String cipherList);
public Pointer SSL_new(Pointer context);
public void SSL_free(Pointer ssl);
...
}
2) Initialize the library:
...
public static OpenSSLLib libSSL;
public static LibEayLib libEay;
...
static {
libSSL = OpenSSLLib.INSTANCE;
libEay = LibEayLib.INSTANCE;
libSSL.SSL_library_init();
libEay.OPENSSL_add_all_algorithms_conf(); // This function is called from
// libeay32.dll via another JNA interface.
libSSL.SSL_load_error_strings();
}
...
3) Create and initialize SSL_CTX and SSL objects:
public class SSLEndpoint {
public Pointer context; // SSL_CTX*
public Pointer ssl; // SSL*
...
}
...
SSLEndpoint endpoint = new SSLEndpoint();
...
// Use one of supported SSL/TLS methods; here is the example for TLSv1 Method
endpoint.context = libSSL.SSL_CTX_new(libSSL.TLSv1_method());
if(endpoint.context.equals(Pointer.NULL)) {
throw new SSLGeneralException("Failed to create SSL Context!");
}
int res = libSSL.SSL_CTX_set_cipher_list(endpoint.context, OpenSSLLib.DEFAULT_CIPHER_LIST);
if(res != 1) {
throw new SSLGeneralException("Failed to set the default cipher list!");
}
libSSL.SSL_CTX_set_verify(endpoint.context, OpenSSLLib.SSL_VERIFY_NONE, Pointer.NULL);
// pathToCert is a String object, which defines a path to a cerificate
// in PEM format.
res = libSSL.SSL_CTX_use_certificate_file(endpoint.context, pathToCert, certKeyTypeToX509Const(certType));
if(res != 1) {
throw new SSLGeneralException("Failed to load the cert file " + pathToCert);
}
// pathToKey is a String object, which defines a path to a priv. key
// in PEM format.
res = libSSL.SSL_CTX_use_PrivateKey_file(endpoint.context, pathToKey, certKeyTypeToX509Const(keyType));
if(res != 1) {
throw new SSLGeneralException("Failed to load the private key file " + pathToKey);
}
res = libSSL.SSL_CTX_check_private_key(endpoint.context);
if(res != 1) {
throw new SSLGeneralException("Given key " + pathToKey + " seems to be not valid.");
}
SSLGeneralException is the custom exception, simply inherited from RuntimeException.
...
// Create and init SSL object with given SSL_CTX
endpoint.ssl = libSSL.SSL_new(endpoint.context);
...
Next steps may be creating of BIO objects and linking them to the SSL object.
Regarding to the original question, client/server secure randoms and the master key may be obtained via such methods:
public int SSL_get_client_random(Pointer ssl, byte[] out, int outLen);
public int SSL_get_server_random(Pointer ssl, byte[] out, int outLen);
public int SSL_SESSION_get_master_key(Pointer session, byte[] out, int outLen);
Please, note, that JNA will search dlls to load looking into jna.library.path parameter. So, if the dlls are located, for example in directory D:\dlls, you must specify such VM option:
-Djna.library.path="D:/dll"
Also, JNA requires 32-bit JRE for 32-bit dlls (probably, libffi constraint?). If you try to load a 32-bit dll using 64-bit JRE, you'll get an exception. | unknown | |
d4964 | train | Maybe you're overthinking this. If I understand what you want correctly, you could just do something like this:
from datetime import datetime, timedelta
days = {
'1': _('Monday'),
'2': _('Tuesday'),
'3': _('Wednesday'),
'4': _('Thursday'),
'5': _('Friday'),
'6': _('Saturday'),
'7': _('Sunday')
}
DOW_CHOICES = []
today = datetime.today()
for i in range(7):
day_number = (today + timedelta(days=i)).isoweekday()
day = days[str(day_number)]
DOW_CHOICES.append((day_number, day))
This gets the today's date and creates a list of tuples with day number and day. The result will be:
[
(3, 'Wednesday'),
(4, 'Thursday'),
(5, 'Friday'),
(6, 'Saturday'),
(7, 'Sunday'),
(1, 'Monday'),
(2, 'Tuesday')
] | unknown | |
d4965 | train | One way you can do this is by using a recursive function. Where each iteration of the function goes 1 level deeper until it reaches the desired level to set the value. This is a basic version assuming objects exists with correct depth before calling the function. As it is now, there can be multiple errors if used incorrectly, should be amended to add more error checks.
var veryDeepTree = {
branch : {
branch : {
branch : {
}
}
}
};
function assignByDepth(subTree, currentTreeDepth, objProperty, value){
if(currentTreeDepth == 1){
subTree[objProperty] = value;
}else{
assignByDepth(subTree[objProperty], --currentTreeDepth, objProperty, value);
}
}
assignByDepth(veryDeepTree, 3, "branch", {branch:10});
console.log(veryDeepTree);
assignByDepth(veryDeepTree, 4, "branch", 5555);
console.log(veryDeepTree); | unknown | |

d4968 | train | c() creates a vector. - makes the numbers in the vector negative. The vector is in the "row" position of [, so it is omitting the rows from 1 to k, and from nrow(SN) - k + 1 to the end of the data frame. So it's chopping off the first k and last k - 1 rows of the data frame. | unknown | |
d4969 | train | I was also facing same issue and I followed these steps and problem went away:
1.close all program in your system then
2.then go to start button and search for %temp% then delete all files inside this folder
3.install Cclean software and clean your system.
4.restart your system
A: I was facing same issue in win7 and I took these steps to resolve the problem:
When starting Android Studio, it warns you with ADB not responding.
If you'd like to retry, then please manually kill the process. You should enter cmd, and input adb kill-server for ten times or more.
When the building has finished, input adb start-server and you will see

d4975 | train | Its the subquery that is killing it - if you add a current field on the player_team table, where you give it value = 1 if it is current, and 0 if it is old you could simplify this alot by just doing:
SELECT
COUNT(*) AS total,
pt.team_id,
p.facebook_uid AS owner_uid,
t.color
FROM
player_team pt
JOIN player p ON (p.id = pt.player_id)
JOIN team t ON (t.id = pt.team_id)
WHERE
player_team.current = 1
GROUP BY
pt.team_id
ORDER BY
total DESC
LIMIT 50
Having multiple entries in the player_team table for the same relationship where the only way to distinguish which one is the 'current' record is by comparing two (or more) rows I think is bad practice. I have been in this situation before and the workarounds you have to do to make it work really kill performance. It is far better to be able to see which row is current by doing a simple lookup (in this case, where current=1) - or by moving historical data into a completely different table (depending on your situation this might be overkill).
A: Try this:
SELECT t.*, cnt
FROM (
SELECT team_id, COUNT(*) AS cnt
FROM (
SELECT player_id, MAX(id) AS mid
FROM player_team
GROUP BY
player_id
) q
JOIN player_team pt
ON pt.id = q.mid
GROUP BY
team_id
) q2
JOIN team t
ON t.id = q2.team_id
ORDER BY
cnt DESC
LIMIT 50
Create an index on player_team (player_id, id) (in this order) for this to work fast.
A: I sometimes find that more complex queries in MySQL need to be broken into two pieces.
The first piece would pull the data required into a temporary table and the second piece would be the query that attempts to manipulate the dataset created. Doing this definitely results in a significant performance gain.
A: This will get the current teams with colours ordered by size:
SELECT team_id, COUNT(player_id) c AS total, t.color
FROM player_team pt JOIN teams t ON t.team_id=pt.team_id
GROUP BY pt.team_id WHERE current=1
ORDER BY pt.c DESC
LIMIT 50;
But you've not given a condition for which player should be considered owner of the team. Your current query is arbitrarily showing one player as owner_id because of the grouping, not because that player is the actual owner. If your player_team table contained an 'owner' column, you could join the above query to a query of owners. Something like:
SELECT o.facebook_uid, a.team_id, a.color, a.c
FROM player_teams pt1
JOIN players o ON (pt1.player_id=o.player_id AND o.owner=1)
JOIN (...above query...) a
ON a.team_id=pt1.team_id;
A: You could add a column "last_playteam_id" to player table, and update it each time a player changes his team with the pk from player_team table.
Then you can do this:
SELECT
COUNT(*) AS total,
pt.team_id,
p.facebook_uid AS owner_uid,
t.color
FROM
player_team pt
JOIN player p ON (p.id = pt.player_id) and p.last_playteam_id = pt.id
JOIN team t ON (t.id = pt.team_id)
GROUP BY
pt.team_id
ORDER BY
total DESC
LIMIT 50
This could be fastest because you don't have to update the old player_team rows to current=0.
You could also add instead a column "last_team_id" and keep it's current team there, you get the fastest result for the above query, but it could be less helpful with other queries. | unknown | |
d4976 | train | The problem is mismatch between json structure and object structure. The object you deserialize into must represent correctly the json. It's an object with a field drinks, which is an array of objects(drinks in your case). Correct java class would be:
public class Wrapper {
private List<Drink> drinks;
//getters and setters
@Override
public String toString() {
return "Wrapper{" +
"drinks=" + drinks +
'}';
}
}
Other option would be to write custom deserializer, which can extract drinks from the tree before deserializing directly into a list.]
Edit: Added toString() override for debugging purposes. | unknown | |

d4979 | train | You should look into creating a Universal app which basically has shared code and libraries for the iPhone and iPad but different view layers (views or XIBs).
In that model you have different interfaces for both which you should. The paradigms are different - in iPhone you have small real estate so you have navigators that drill in and pop out. In iPad, you have more real estate so you have master/detail splitter views with pop-over controls. As you pointed out, even the web views are different sizes at a minimum.
If you start fresh you can create a universal app and get a feel for how it's laid out. File, new project, iOS, pick app type, next. For device family select Universal.
If you are converting, there's some resources out there. Here's some:

Then I include the new separate XIBS in the project and do conditional loading (eg - use the UI_USER_INTERFACE_IDIOM() makro to load one xib or another.) | unknown | |

A: Another way (a bit shorter) would be to use a with clause having an if condition checking for the file size:-
def RotateFile(count, file_size, file_name):
indX = 0
while indX < count:
with open(file_name,"a") as fd:
##
fd.write("DUMMY TEXT\n")
##
if int(os.path.getsize(file_name)) > file_size:
indX += 1
file_name = "new_file"+str(indX)+".txt"
with statement creates a context manager, so by the time you reach the end of if condition , the file object in fd will have been automatically closed.
Next is to specify the options you need and pass on to the method:
if __name__ == "__main__":
count = 10 ## 10 number of files
file_size = 10000 ## 10KB in size
file_name = "new_file.txt" ## with this name
RotateFile(count, file_size, file_name)
After execution, it will give 10 files of size 10KB each (in the current dir)... | unknown | |
d4987 | train | You can configure what you want to happen when a mass assignment happens by setting Player.mass_assignment_sanitizer (or set it on ActiveRecord::Base for it to apply to all AR models)
You can also set it in your configuration files via config.active_record.mass_assignment_sanitizer
Our of the box you can set it to either :logger, which just logs when these things happen or :strict which raises exceptions. You can also provide your own custom sanitizer. The current application template sets it to strict, although that used not to be the case
A: Comment out this line in development.rb:
config.active_record.mass_assignment_sanitizer = :strict
The strict setting will raise an error and the default setting will just log a warning. | unknown | |

d4989 | train | The issue is
min <- which.min(hospital_data$outcome)
and 'outcome' is passed as a string, but it is just literally using 'outcome' instead of the value passed in the function. It looks for the column 'outcome' in the data.frame and couldn't find it.
df1 <- data.frame(col1 = 1:5)
outcome <- 'col1'
df1$outcome
#NULL
df1[[outcome]]
Use [[ instead of $
min <- which.min(hospital_data[[outcome]]) | unknown | |
d4990 | train | Consider the below approach. I used timestamp functions to create the query.
with sample_data as (
select date('2017-08-04') as date, time(10,00,00) as hour
)
select
format_timestamp( "%d-%b-%y %H%M%S", timestamp_trunc(timestamp(concat(date, ' ',hour),"UTC"),DAY,"America/New_York")) as out_format
from sample_data
NOTE: I created the sample data based from the query you have presented on your question. Let me know if I used incorrect data so I can edit the answer.

d4992 | train | UIKit does not support that.
The only possibilities are sheet to full screen and page sheet to form sheet on iPad. As specified in the documentation :
In a horizontally compact environment, this option behaves the same as UIModalPresentationFullScreen.
So UIKit already adapts it.
Unfortunately you will have to implement your own custom transition controller.
A: As GaétanZ said, better use another modal presentation style like overFullScreen for compact horizontal size clases and leave the formSheet for the horizontally regular ones.
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
if controller.traitCollection.horizontalSizeClass == .regular {
return .formSheet
}
return .overFullScreen

d4993 | train | Items in STL containers are expected to be copied around all the time; think about when a vector has to be reallocated, for example. So, your example is fine, except that it only works with random iterators. But I suspect the latter is probably by design. :-P
A: Do you want your range to be usable in STL algorithms? Wouldn't it be better off with the first and last elements? (Considering the fact that end() is oft required/used, you will have to pre-calculate it for performance.) Or, are you counting on the contiguous elements (which is my second point)?
A: The standard algorithms don't really use operator[], they're all defined in terms of iterators unless I've forgotten something significant. Is the plan to re-implement the standard algorithms on top of operator[] for your "ranges", rather than iterators?
Where non-mutating algorithms do use iterators, they're all defined in terms of *it being assignable to whatever it needs to be assignable to, or otherwise valid for some specified operation or function call. I think all or most such ops are fine with a value.
The one thing I can think of, is that you can't pass a value where a non-const reference is expected. Are there any non-mutating algorithms which require a non-const reference? Probably not, provided that any functor parameters etc. have enough const in them.
So sorry, I can't say definitively that there are no odd corners that go wrong, but it sounds basically OK to me. Even if there are any niggles, you may be able to fix them with very slight differences in the requirements between your versions of the algorithms and the standard ones.
Edit: a second thing that could go wrong is taking pointers/references and keeping them too long. As far as I can remember, standard algorithms don't keep pointers or references to elements - the reason for this is that it's containers which guarantee the validity of pointers to elements, iterator types only tell you when the iterator remains valid (for instance a copy of an input iterator doesn't necessarily remain valid when the original is incremented, whereas forward iterators can be copied in this way for multi-pass algorithms). Since the algorithms don't see containers, only iterators, they have no reason that I can think of to be assuming the elements are persistent.
A: Since you put "container" in "quotes" you can do whatever you want.
STL type things (iterators, various member functions on containers..) return references because references are lvalues, and certain constructs (ie, myvec[i] = otherthing) can compile then. Think of operator[] on std::map. For const references, it's not a value just to avoid the copy, I suppose.
This rule is violated all the time though, when convenient. It's also common to have iterator classes store the current value in a member variable purely for the purpose of returning a reference or const reference (yes, this reference would be invalid if the iterator is advanced).
If you're interested in this sort of stuff you should check out the boost iterator library. | unknown | |
d4994 | train | Older versions of Greasemonkey will ignore the @match directive, but will not break.
For maximum compatibility, use the @include and @exclude directives to control where/when a script runs.
Update:
As of Greasemonkey 0.9.8, GM fully supports the @match directive. | unknown | |

d4996 | train | Here is the RubyGems guide for how to add an executable.
The primary steps are:
*
*Add your script to the gem's /bin directory
*Your script must be executable in the filesystem chmod a+x bin/<yourfile>
*Make sure your script starts with a proper shebang
*Add the script to the .executables section of your gemspec
Note you will still have to build and install your gem locally to run the command without a path as you are trying to do in the screenshot.

d4997 | train | Peter, I believe your problem has to do with the width of your logo under the class "navbar-brand". I had a similar issue, but fixed it by controlling the width of my logo under the Navbar-brand. According to bootstrap, "Adding images to the .navbar-brand will likely always require custom styles or utilities to properly size." Below is bootstraps example:
<!-- Just an image -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">
<img src="/docs/4.4/assets/brand/bootstrap-solid.svg" width="30" height="30" alt="">
</a>
</nav>
Notice the width and height settings after the image. In my case I was able to change the width of my logo image in CSS within my media query for small screen sizes. | unknown | |
d4998 | train | I got the admin guy to copy SDK folder from his directory under C:\Users\adminguy\AppData to somewhere I can read. Now it works ok. | unknown | |
d4999 | train | Thats what directives are designed for, point is to figure out best way to pass and evaluate those attributes of fields, in plnkr i made a possible solution.
Here you have a starting point:
PLNKR
app.directive('cmsInput', function() {
return {
restrict: 'E',
template: '<label ng-if=(exists(label))>{{label}}</label>',
controller: function($scope) {
$scope.exists = function(a) {
if(a && a.length>0) {
return true;
}
return false;
}
},
link: function(scope, elem, attr) {
scope.label = attr.label;
}
}
})
It requires work, but you'll get the point.
EDIT:
You could use 'scope' field of directives to bind values, but for purpose of finding solution I wanted to make it as clear as possible.
EDIT2:
Angular directive is being define with a rule "camelCase" in javascript(directive name) is eaxctly "camel-case" in html, as a directive call.
Angular matches correct js code to called directive and puts exactly in that place in DOM your template. One of the parameters of link method are attributes, those are the same values that you have in html, so under:
'attr.label' you get value of 'label' in html, in this case string "header".
The template attribute of directive is a string with bindigs to variables that were set in scope and and when we combine it all together we get:
*
*Angular "finds" a directive
*Directive code is being fired
*Link function is being called - inside which we set to field named "label" value of attribute named "label"
*Template compiles - under {{ }} markers correct variables are being set.
*vio'la - in place of this cms-input element you get normal html | unknown | |
