d5701 | train | Here I have written simple code for pagination design. You can use it.
HTML for pagination
<a>1</a>
<a>2</a>
<a>3</a>
Style for pagination link
<style>
a::after {
content: " /";
margin: 0 5px;
}
a:last-child::after {
display: none;
}
</style>
Your pagination link will be look like below
You can modified the design as per your site.
Hope this will work for you! | unknown | |
d5702 | train | When you use the canvas as both source and destination, the browser is required to do (there are finer steps involved, but these are the main ones):
*
*Create a scratch bitmap to copy to
*Copy current bitmap into scratch bitmap
*Copy scratch bitmap back to original bitmap at a different position (ie. drawImage(canvas,...));
*Remove scratch
This instead of when you use separate canvases:
*
*Copy source bitmap to destination bitmap
Why not just "blitting"? The official standard define this case in this way (my emphasis):
When a canvas or CanvasRenderingContext2D object is drawn onto itself,
the drawing model requires the source to be copied before the image is
drawn, so it is possible to copy parts of a canvas or scratch bitmap
onto overlapping parts of itself.
Also take a look at the Drawing Model for the steps involved. | unknown | |
d5703 | train | You want something like this:
class User < ActiveRecord::Base
has_many :writings
has_many :posts, :through => :writings
has_many :readings
has_many :read_posts, :through => :readings, :class_name => "Post"
#..
end
By giving the association name something other than just :posts you can refer to each one individually. Now...
@user.posts # => posts that a user has written via writings
@user.read_posts # => posts that a user has read via readings | unknown | |
d5704 | train | Alright, I feel like this was not really a problem at all to begin with as I discovered the DeserializeObject(string, Type, JsonSerializerSettings) overload for the method. It works splendidly. However, I would still like to hear some feedback on the approach. Do you think using attributes as a way to resolve the type names is reasonable or are there better ways? I don't want to use the class names directly though, because I don't want to risk any sort of man-in-the-middle things be able to initialize whatever.
A: Just a few minutes ago we have posted the alternative way to do what you want. Please look here, if you will have any questions feel free to ask:
Prblem in Deserialization of JSON
A: Try this
http://json2csharp.com/
Put your Json string here it will generate a class
then
public static T DeserializeFromJson<T>(string json)
{
T deserializedProduct = JsonConvert.DeserializeObject<T>(json);
return deserializedProduct;

Browse his file again or e.g., my http://maps.google.com/maps?q=http:%2F%2Fjidanni.org%2Flocation%2Fzaokeng.kmz
Unclicking boxes in the LEFT panel no longer turns off that layer!
They used to turn on and off what they referred to, that is why they are clickable checkboxes.
Now they don't work on any KML map anywhere! (Broken now in Google Maps, but still works OK in Google Earth though.)
Furthermore, e.g., turning on the (panoramio) photo layer in the RIGHT pull down menus loses the LEFT panel's menus for
the rest of the session no matter what.
In conclusion viewing KML files in Google Maps is now at an all time bug threatened low! | unknown | |

d5708 | train | Turns out I actually did need to uninstall the platform, remove the plugin json file, and then reinstall everything.
A: Run (this will remove the old ionic ios platform)
sudo ionic platform rm ios
Then (this will install a new platform with privileges)
sudo ionic platform add ios
Then build your code ios/android
ionic build ios
ionic build android
This fixed it for me!
Might be that you should also run
sudo ionic resources
to generate new icon and splash screens.
A: Basically, re-installation of Platform and Plugins once again resolves the issue. | unknown | |
d5709 | train | I think you're going to need a custom expectation. Based on the testthat pkgdown site, it might look something like this:

d5710 | train | you don’t need a select … from dual, just write:
SELECT t.*, dbms_random.value(1,9) RandomNumber
FROM myTable t
A: Something like?
select t.*, round(dbms_random.value() * 8) + 1 from foo t;
Edit:
David has pointed out this gives uneven distribution for 1 and 9.
As he points out, the following gives a better distribution:
select t.*, floor(dbms_random.value(1, 10)) from foo t;
A: If you just use round then the two end numbers (1 and 9) will occur less frequently, to get an even distribution of integers between 1 and 9 then:
SELECT MOD(Round(DBMS_RANDOM.Value(1, 99)), 9) + 1 FROM DUAL
A: At first I thought that this would work:
select DBMS_Random.Value(1,9) output
from ...
However, this does not generate an even distribution of output values:
select output,
count(*)
from (
select round(dbms_random.value(1,9)) output
from dual
connect by level <= 1000000)
group by output

d5711 | train | There are some helpful graphics on pywt webpage that help visualize what these thresholds are and what they do.
The threshold applies to the coefficients as opposed to your raw signal. So for denoising, this will typically be the last couple of entries returned by pywt.wavedec that will need to be zeroed/thresholded.
I could initial guess is the 0.5*np.std of each coefficeint level you want to threshold. | unknown | |

First, there is no requirement that the user chooses an email client for this startActivity() request.

d5718 | train | No boxing, compiler uses the ldloca.s instruction which pushes a reference to the local variable onto the stack (http://msdn.microsoft.com/en-us/library/system.reflection.emit.opcodes.ldloca_s(VS.71).aspx)
.method private hidebysig static void Func() cil managed
{
.maxstack 2
.locals init (

L_0008: call bool [mscorlib]System.Int32::TryParse(string, int32&)
L_000d: stloc.1
L_000e: ret
}
A: No, there is no Boxing (required/involved).
When you do Box a variable, changes to the boxed instance do not affect the original. But that is exactly what out is supposed to do.
The compiler 'somehow' constructs a reference to the original variable.
A: As others have pointed out, there's no boxing here. When you pass a variable as an argument corresponding to an out or ref parameter, what you are doing is making an alias to the variable. You are not doing anything to the value of the variable. You're making two variables represent the same storage location.
Boxing only happens when a value of a value type is converted to a value of a reference type, and there's no conversion of any kind in your example. The reference type must of course be System.Object, System.ValueType, System.Enum or any interface. Usually it is pretty clear; there's an explicit or implicit conversion in the code. However, there can be circumstances where it is less clear. For example, when a not-overridden virtual method of a struct's base type is called, there's boxing. (There are also bizarre situations in which certain kinds of generic type constraints can cause unexpected boxing, but they don't usually come up in practice.)
A: There is no boxing; what the out parameter does is specifies that number must be assigned to within the TryParse method. Irrespective of this, it is still treated as an int, not an object. | unknown | |
d5719 | train | Having used Java Pathfinder some time back, I know that its not an applet as the other answer worries.
You are getting this error because the Java Pathfinder jar files are not on your classpath. Here is a complete Java Pathfinder Getting Started tutorial that could help others coming to this old thread.
A: It's not a URL at all (except in the case of applets, and you didn't mention an applet). You need to put the Pathfinder jar in the classpath when compiling and running, via -cp to javac and java.
If it's an applet, it's more complex. | unknown | |
d5720 | train | No all characters are allowed in a xml files. Here is a link for you to find which one is allowed or is discouraged and the reset is not allowed:
http://en.wikipedia.org/wiki/Valid_characters_in_XML
Yours (→) is not allowed.
A: I resolved this by using below code
String removedUnicodeChar = "DISPOSABLE COVERALL → XXL</Description></Order> ↔ ↕ ↑ ↓ → ABC";
Pattern pattern = Pattern.compile("[\\p{Cntrl}|\\uFFFD]");
Matcher m = pattern.matcher(removedUnicodeChar);
if(m.find()){
System.out.println("Control Characters found");
removedUnicodeChar = m.replaceAll("");
} | unknown | |
d5721 | train | You could do an ArrayList of the characters found in your secret.
Then use .contains(Char c) method from the ArrayList
An Example:
ArrayList<Char> secret = new ArrayList<Char>();
secret.add('w');
secret.add('o');
secret.add('r');
secret.add('l');
secret.add('d');
if(secret.contains(new Char('x')) {
System.out.println("Found");
} else {
System.out.println("Not Found");
}
A: I think this might be homework, so gtgaxiola's answer could be something the teacher doesn't want to see. Here is how to implement the equivalent of .contains() on a normal array of chars so you don't have to change too much in your current code.
char[] secretCh = new char[]{'s', 'e', 'c', 'r', 'e', 't'};
char guessCh = 'e';
boolean found = false;
for(int i = 0; i < secretCh.length; i++) { // loop through each character in the secretCh array
if (secretCh[i] == guessCh) {
found = true;
break;
}
}
if (found)
System.out.println("guessCh is a letter in the secret word.");
A: The String object already has this functionality built in.
All you really need is something like this:
if(secretStr.indexOf(guessCh) < 0) nTurnsLeft--;
indexOf returns the index of the location of the char guessCh inside the String secretStr. If guessCh is not found, then indexOf returns -1; | unknown | |

d5725 | train | This problem occurs because your code try to using non-existing pointer in cocoa pods. You may using framework that using cocoa pods and install needed pods on the main project.
The solution is to make cocoa pods version similar in both framework and project , run pod update from the terminal in both framework and project or specify every pod version to be same in both
Example
framework pod file :
pod 'GooglePlaces' '~> 3.1.0'
project pod file :
pod 'GooglePlaces' '~> 3.1.0'

d5726 | train | You won't be able to get the grid object by dojo.byId("_selectedDataGrid"). It is better to keep the myGrid object at class level (widget level) and connect using dojo.hitch.
dojo.connect(this.myGrid, 'onRowClick', dojo.hitch(this, function(){
//access myGrid using this.myGrid and do the handling
}));
A: From what you have share, I can see that the node "_selectedDataGrid" is just a Div tag. and your dataGrid widget may be "this._selectedGrid" so you should be add the event on that widget not the container node.
Also there is dijit.byId to get the instance of dijits/widgets. and dojo.byId is used to search of dom nodes.

d5730 | train | I apologize that the question was vague. However we had no clue what was causing the problem so what facts would have been relevant?
At any rate it turns out we have two web apps running under IIS, both are trying to create ActiveX components. As soon as we turn one of the web apps off the problem goes away.
After we verified this behavior, we tried calling some simple ActiveX components (like excel). Lo and behold exactly the same behavior as long as there are more than two web apps running.
Our solution for now is to host the second web app elsewhere. | unknown | |

Parameters
l: The ListView where the click happened
v: The view that was clicked within the ListView
position: The position of the view in the list
id: The row id of the item that was
clicked

d5733 | train | Following cron expression will run 14 days once
0 5 */14 * * /your/command/
If you like to run only once from current date on 20th September 2018
0 0 20 9 ? 2018 /command
WARNING: The year column is not supported in standard/default implementations of cron.
A: Run a cron-job every 14 days starting from day X
If you want to do this, have a look at this answer.
Run a cron-job only ones 14 days after day X
If you want to do this, there are a few options you have. Assume that day X is today (2018-09-06), then I give you the following options:
# Example of job definition:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7)
# | | | | |
# * * * * * command to be executed
0 0 6 9 * [[ `date '+\%Y'` == "2018" ]] && sleep 1209600 && command1
0 0 20 9 * [[ `date '+\%Y'` == "2018" ]] && command2
0 0 * * * /path/to/daytestcmd 14 && command3
*
*The first option here is simply checking if the year is correct. If so, sleep for 14 days and then execute command1
*The second option is by computing the day itself and execute the script on that day. Again, you have to check manually for the correct year.
The third option is much more flexible for your purpose. The idea is to create a script called daytestcmd which does the check for you. The advantage of this script is that you only need to update one line in the script to change the test and never change the cronjob. The script would look something like:
#/usr/bin/env bash
# Give reference day
reference_day="20180906"
# Give the number of days to await execution (defaults to zero)
delta_days="${1:-0}"
# compute execution day
execution_day=$(date -d "${reference_day} + $delta_days days" "+%F")
[[ $(date "+%F") == "$execution_day" ]]
So, the next time you want to wait 14 days, just update the script and change the variable reference_day.
note: the OP updated the question. The above script can also be adjusted where reference_day is obtained via a set of commands, for example to retrieve the day of dev deployment. Imagine get_dev_deployment_day is a command which returns that day, then you just need to update
reference_day=$(get_dev_deployment_day) | unknown | |

(Note that the setTimeout(() => {...}, 1) allows the current confirm dialog to clear before the service tries to open the next one.)

d5737 | train | Could use something similar:
public static readonly char[] CHARS = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z' };
static void Main(string[] args)
{
static string GenerateGlitchedString(uint wordCount,uint wordslength)
{
string glitchedString = "";
for (int i = 0; i < wordCount; i++)
{
for (int j = 0; j < wordslength; j++)
{
Random rnd = new Random();
glitchedString += CHARS[rnd.Next(CHARS.Length)];
}
glitchedString += " "; //Add spaces
}
return glitchedString;
}
string output = GenerateGlitchedString(5, 5);
Console.WriteLine(output);
}
A: You can use Linq to generate any number of random characters from an enumerable:
int howManyChars = 5;
var newString = String.Join("", Enumerable.Range(0, howManyChars).Select(k => st[Random.Range(0, st.Length)]));
textbox.text = newString;
A: If you want completely glitchy strings, go the way of Mojibake. Take a string, convert it to one encoding and then decode it differently. Most programmers end up familiar with this kind of glitch eventually. For example this code:
const string startWith = "Now is the time for all good men to come to the aid of the party";
var asBytes = Encoding.UTF8.GetBytes(startWith);
var glitched = Encoding.Unicode.GetString(asBytes);
Debug.WriteLine(glitched);
consistently results in:
潎⁷獩琠敨琠浩潦污潧摯洠湥琠潣敭琠桴楡景琠敨瀠牡祴
But, if you just want some text with some random glitches, how about something like this. It uses a set of characters that should be glitched in, a count of how many glitches there should be in a string (based on the string length) and then randomly inserts glitches:
private static Random _rand = new Random();
private const string GlitchChars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890!@#$%&";
public static string GlitchAString(string s)
{
var glitchCount = s.Length / 5;
var buffer = s.ToCharArray();
for (var i = 0; i < glitchCount; ++i)
{
var position = _rand.Next(s.Length);
buffer[position] = GlitchChars[_rand.Next(GlitchChars.Length)];
}
var result = new string(buffer);
Debug.WriteLine(result);
return result;
}
The first two times I ran this (with that same Now is the time... string), I got:
Original String:
Now is the time for all good men to come to the aid of the party
First Two Results:
LowmiW HhZ7time for all good mea to comX to ths aid oV the p1ray
Now is fhO P!me forjall gKod men to @ome to the a@d of F5e Nawty
The algorithm is, to some extent, tunable. You can have more or fewer glitches. You can change the set of glitch chars - whatever you'd like. | unknown | |
d5738 | train | As per the documentation the reflected form of __lt__() is __gt__().
There are no swapped-argument versions of these methods (to be used when the left argument does not support the operation but the right argument does); rather, __lt__() and __gt__() are each other’s reflection, __le__() and __ge__() are each other’s reflection, and __eq__() and __ne__() are their own reflection. If the operands are of different types, and right operand’s type is a direct or indirect subclass of the left operand’s type, the reflected method of the right operand has priority, otherwise the left operand’s method has priority. Virtual subclassing is not considered. | unknown | |
d5739 | train | gperftools uses autoconf/automake, so you can do
./configure --prefix=/path/to/whereever

make install
This works for all autotools projects, unless they are severely broken.

d5740 | train | Looks to me like it might be an off-by-one error. When you call malloc, you are allocating enough space for an array of length elements. Arrays are 0-indexed -- that is, points[0] to points[length-1] are valid memory addresses, while points[length] is not.
At the end of your first loop, the last point you set is one element past the end of the array, and it's possible that the value gets overwritten by something by the time you try to draw the last line segment.
Try changing your first loop to be:
for(i=0; i < length; i++) {
// scanf stuff here
}
and your second loop to:
for(i=0; i < length-1; i++)
// cvLine stuff here | unknown | |

d5742 | train | You need to first understand underline problems that isolation level resolves.
*
*Dirty read(I saw updated record however it disappeared again)
*Non repeatable read(Update - I saw an updated value but now value has
changed. Oh someone rolled back.)
*Phantom read(Insert - This appeared as a ghost and then disappeared)
Try to play around on two connections. First run connection 1 script then connection 2 script without committing anything. Once both scripts are executed then try to commit connection 1.
READ UNCOMMITTED - Connection running under this isolation level can read rows that have been modified by other transactions but not yet committed.
READ COMMITTED - Connection running under this isolation level cannot read data that has been modified but not committed by other transactions.
REPEATABLE READ - Transaction running under this isolation level cannot read data that has been modified but not yet committed by other transactions and that no other transactions can modify data that has been read by this transaction until the this transaction completes. This is done by placing shared lock on records read by this transaction. Having a shared on lock record, no other transaction can modify this record until this transaction completes.
SERIALIZABLE - Same conditions as we have for repeatable read with an addition of one more condition i.e. Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.
Think of a record as inserting a record between date range. You are trying to insert a record between the date range read by another connection.
DIRTY READ

SET TRANSACTION ISOLATION LEVEL READ COMMITTED
BEGIN TRAN
UPDATE tbl SET Col1 = 'Dummy' WHERE ID = 1

Connection 2

d5743 | train | Inside of a function, the function's name can be used as a substitute for using an explicit local variable or Result. freq() and OddUserName() are both doing that, but only freq() is using the function name as an operand on the right-hand side of an assignment. freq := freq + 1; should be a legal statement in modern Pascal compilers, see Why i can use function name in pascal as variable name without definition?.
However, it would seem the error message is suggesting that the failing compiler is treating freq in the statement freg + 1 as a function type and not as a local variable. That would explain why it is complaining about not being able to add a ShortInt with a function type.
So, you will have to use an explicit local variable instead, (or the special Result variable, if your compiler provides that), eg:
function freq(charToFind: char; username : String): Integer;
var
i, f: Integer;
begin
f := 0;
for i := 1 to Length(username) do
if charToFind = username[i] then
f := f + 1;
//writeln(f);
freq := f;

function freq(charToFind: char; username : String): Integer;

Why do I get an outputpattern like B@#, where # is a number. I think it has something to do with indirect adressing but im not quite sure. Why doesn't it print out 100 s?
A: You are printing the array rather than the object in the array. As a result, it is printing the address of the object (the number) and the object it is a member of.
I suspect you wanted to call each of the prints, you should, in B.print(). You are also missing an increment for i, meaning it will loop indefinitely.
for(int i = 0; i < 100; ++i)
{
a[i].print();

d5746 | train | There is no need to do this. Have you tried it without casting them to ints? If you are not able to do this post what version of laravel you are using so people who come across this later don't do needless work. In laravel 4.2.* the following code will return the proper rows. I have just tested this.
Route::get('/', function(){
$t = DB::table('users')->whereIn('id', array('1','2','3'))->get();
dd($t);
});
This also works.
Route::get('/', function(){
$t = DB::table('users')->whereIn('id', array(1,2,3))->get();
dd($t);
});
Furthermore this code you have
array(4) { [0]=> string(1) "1" [1]=> string(1) "4" [2]=> string(1) "6" }
And this code are exactly the same. One has just being displayed using var_dump.
array("1", "4", "6")
Unless you are literally storing unserialized arrays in your database in which case you have a ton of other issues.
EDIT: After controller was posted
I don't believe whereIn takes 3 parameters. You are trying to cast '=' to an array in your whereIn statements remove this and it should work or at least get ride of the Array to string error.
Link to whereIn Laravel function.
A: First: I think Laravel can handle string typed items to be put in a sql where clause where the column is an integers.
Second: if it doesn't work you can always 'cast' those strings to integers with the array_map method.
More information here:
http://php.net/manual/en/function.array-map.php
In your example:
$ids = array('1', '4', '6');
$ids = array_map(function ($value) {
return (int) $value;
}, $ids);
$users = DB::table('users')->whereIn('id', $ids)->get();

d5754 | train | On the frontend, you are making an HTTP request with the GET method, which has no body. On the backend, req.body.id will be undefined because there is no request body in the first place.
So you have several options:
First: use a POST request on the front end
axios({
method: 'POST',
url:"http://localhost:3000/recette/rec_recette",
headers: {},
data: {
id: 'votre_id_ici', // This is the body part
}
});
The backend code to handle the post request:
(Use async/await to make the code cleaner)
router.post('/recette_light', async (req, res) => {
try {
// Assuming you are searching for your recette using MongoDB doc.id
const cat_recette = await db.cat_recette.findById(req.body.id);
// If there are no matching docs.
if (!cat_recette) {
return res.json("il n'y a pas de cat_recettes");
}
// Otherwise send the data to the frontend
res.status(200).json({ cat_recette: cat_recette, });
} catch (err) {
console.log(err);
res.status(500).json({ msg: 'Server Error', });
}
});
Second: use the GET method still but with URL parameters
axios.get("http://localhost:3000/recette/rec_recette/votre_id_ici")
The backend code to handle it:
// Note the /:id at the end
router.get('/recette_light/:id', async (req, res) => {
try {
// Assuming you are searching for your recette using MongoDB doc. id
// Note the req.params.id here not req.body.id

d5756 | train | With attribute routing, you just need to decorate your action method with your specific route pattern.
public class ProductController : Controller
{
EFDbContext db = new EFDbContext();
private IProductsRepository repository;
public int PageSize = 4;
public ProductController (IProductsRepository productrepository)
{
this.repository = productrepository;
}
[Route("Product/list/{category}/{page}")]
public ViewResult List(string category, int page = 1)
{
// to do : Return something
}
}
The above route definition will send the request like yourSite/Product/list/phones and yourSite/Product/list/phones/1 to the List action method and the url segments for category and page will be mapped to the method parameters.
To enable attribute routing, you need to call the method MapMvcAttributeRoutes
method inside the RegisterRoutes method.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
A: To generate an URL like you want: localhost/Product/List/Cars you can create a custom route like this:
routes.MapRoute(
name: "ProductList",
url: "Product/List/{category}",
defaults: new { controller = "Product", action = "List" }
);
Remember that custom routes have to come before the most general route (the one that comes with the default template).
Regarding your page parameter, if you are comfortable with this URL: localhost:3288/Product/List/teste?page=10 the above already work. But if you want this: localhost:3288/Product/List/teste/10 10 meaning the page number, then the simplest solution would be create two different routes:
routes.MapRoute(
name: "ProductList",
url: "Product/List/{category}",
defaults: new { controller = "Product", action = "List" }
);
routes.MapRoute(
name: "ProductListPage",
url: "Product/List/{category}/{page}",
defaults: new { controller = "Product", action = "List" , page = UrlParameter.Optional}
);
Another cleaner way, is to create a custom route constraint for your optional parameter. This question has a lot of answers to that:

d5759 | train | std::bind stores copies of its arguments (here a move-constructed future), and later, uses them as lvalue arguments (with some exceptions to that rule that include reference wrappers, placeholders and other bind expressions; none applicable here).
std::future is not copy-constructible. That is, a function that accepts a parameter by-value, of a type that is not copy-constructible, like your callback does, is not callable with an lvalue.
In order to make your code work, you need to adjust the signature of the callback:
std::function<void(std::future<my_result_t>&)> callback = [] (auto& result) {
// ~^~ ~^~
Preferably, though, don't use std::bind at all.
A: It might be worth mentioning that the actual solution is used was to replace the bind by a lambda. What I forgot to mention in my question was that changing the signature of the callback to a reference is not a suitable option for me, since the f callable will be copied/moved into an asynchronous queue, i.e. reactor pattern, i.e. boost::asio::post. A reference would rise lifetime challenges for the lifetime of that future. I didn't mentioned it first since I hope it would still be somehow possible with std::bind, but @piotr-skotnicki did nicely explain why its not possible. So for completeness of other searches without further ado:
std::future<my_result_t> future = promise.get_future();
auto f = [callback, future = std::move(future)] () mutable{

A: No. EDIT: A CURLINFO_CERTINFO option has been added to PHP 5.3.2. See http://bugs.php.net/49253
Apparently, that information is being given to you by your proxy in the response headers. If you want to rely on that, you can use curl's CURLOPT_HEADER option to trueto include the headers in the output.
However, to retrieve the certificate without relying on some proxy, you must do
<?php
$g = stream_context_create (array("ssl" => array("capture_peer_cert" => true)));
$r = fopen("https://www.google.com/", "rb", false, $g);
$cont = stream_context_get_params($r);
var_dump($cont["options"]["ssl"]["peer_certificate"]);
You can manipulate the value of $cont["options"]["ssl"]["peer_certificate"] with the OpenSSL extension.
EDIT: This option is better since it doesn't actually make the HTTP request and does not require allow_url_fopen:
<?php
$g = stream_context_create (array("ssl" => array("capture_peer_cert" => true)));
$r = stream_socket_client("ssl://www.google.com:443", $errno, $errstr, 30,
STREAM_CLIENT_CONNECT, $g);
$cont = stream_context_get_params($r);
var_dump($cont["options"]["ssl"]["peer_certificate"]);
A: To do this in php and curl:
<?php
if($fp = tmpfile())
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://www.digicert.com/");
curl_setopt($ch, CURLOPT_STDERR, $fp);
curl_setopt($ch, CURLOPT_CERTINFO, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
$result = curl_exec($ch);
curl_errno($ch)==0 or die("Error:".curl_errno($ch)." ".curl_error($ch));
fseek($fp, 0);//rewind
$str='';
while(strlen($str.=fread($fp,8192))==8192);

d5763 | train | You can use a simple regular expression for this:
boolean matches = s.matches("^X+Y*$");
This means:
*
*^ matches the start of the string
*X+ means one or more consecutive Xs
*Y* means zero or more consecutive Ys
*$ is the end of the string
Alternatively, you can check the string character-wise:
int i = 0;
while (i < s.length() && s.charAt(i) == 'X') {
++i;
}
if (i < s.length()) {
if (s.charAt(i) != 'Y') {
return false;
}
while (i < s.length() && s.charAt(i) == 'Y') {
++i;

return i == s.length();
A: You can use the following regular expression to detect the particular pattern.
String pattern = "^(X){1,}Y*$";

d5764 | train | A single & is a bitwise AND, which means that the result is the bits that are set on BOTH left and right side of the operator.
As an example 15 & 7 or as they are represented in binary:
1111
&
0111
The bitwise AND will result in the a number with the common bits set:
1111 & 0111 = 0111
When you make the (a & 1) you are testing whether the least significant bit (lsb) is set, since you are performing a test like this:
a
&
00000001
If a had the bitwise value: 00000110 then the result would be 0, since there are no common bits set, if a had the bitwise value: 00000111 then the result would be 1 since the lsb is set on a.
This is used for different situations, if the lsb is set you know that the number is odd, so this test is really whether the number is odd or not (1, 3, 5, 7, ...).
Looking at the first part of your solution: a * (a & 1) you are multiplying a with the value of (0 or 1 remember), 1 if a is odd, and 0 if it is even.
A: Here & is a Bitwise Operator(works on bits and perform bit-by-bit operation).For more details see this and this | unknown | |

d5775 | train | a. \d implies digit.
b. + sign implies one or more occurance of previous character.
c. \. -> since . is a special character in regex, we have to escape it with \.
d. Also, \ is a special escape character in java , hence from java perspective we need to add an additional \ to escape the backslash (\).
Thus, the pattern will reprent any number like:
0.01, 0.001, 1.0001, 100.00001 and so on.
Basically any decimal number with a digit before and after the decimal point.
A: The regex is a simplified version to recognize floating-point numbers: At least one digit optionally followed by a dot and at least a digit.
It's simplified because it only covers only number without a sign (i.e. only positive numbers, because you can't provide a - minus sign), it allows number presentations that are considered invalid, e.g. 000123.123 and lacks the support of numbers written in scientific syntax (e.g. 1.234e56). | unknown | |
d5776 | train | In Unit Tests, you should only test your controller's Java code, without using any Servlet technology.
In integration tests you can do one of several things:
Use the org.springframework.mock.web package in the spring-test artifact, which contains Mock Objects for request, response, servletContext to fire fake requests at your controllers and read the data from the fake responses.
Or use a web testing framework like Selenium that works against a deployed webapp.
A:
How do I test that this create() method gets called when somebody requests http://example.com/create url.
Looks really like a integration test. Sean Patrick Floyd already mentioned some ways how to test that, but to my understanding none of this options really tests that a request to an url really invokes the method. -- The mocking way simulates the request and the selenium test tests only the return value, but not the Invocation. -- Don't get my wrong, I believe that this two other tests are in most cases better (easyer to test and even more valid test results), but if you really want to test the invokation I would come up with this solution.
Use a web testing framework like Selenium (or Selenium 2/Webdriver) or only a simple one that only generates HTTP requests. -- To do that tests you will need of curse the deployed application. -- so it is realy an integration test.
To check that the method is invoked. I would recommend to use a logging tool (Log4J). Then use a Tool like AspectJ or Spring AOP Support to add logging statements to your controller method. The logging should be written to some logger that writes to an other destination then the other loggers you use.
At the end the last step is, that you need to verify that the expected logging statement is is the logfile after the test sends the http request. (Pay attention to the fact, that the logging may is asynchronous.) | unknown | |
d5777 | train | Since products is list of Product, you have to iterate over that list. On thymeleaf you can use th:each attribute to do iteration. So for your case you can use something as below. Give it a try.
<th:each="product,iterStat: ${products}" th:if="${iterStat.index} <3">
I am not entirely sure but based on your question you wanted only first three objects. For this you can use status variable that are defined in th:each. More detail you can find here.
A: Here's the way you do it with the #{numbers} context object.
<th:block th:each="i: ${#numbers.sequence(0, 2)}" th:with="product=${products[i]}">

use:
.nav li{
width: 100%;
margin-bottom: 0;
}
if you don't want to have a margin
.nav{
margin: 0;
padding: 0;
}
A: I'm not entirely sure what you'd like it to look like with 100% width. If you give a little more information I can help further.
However, I noticed a few things that might be confusing your CSS.
1) The height is showing as "0" due to a float being applied to the list items. When you apply float to your items they are removed from the normal flow of the document.
To solve, try first removing this:
.nav li {
float: left;
}
2) Most browsers add default padding and/or margin to ol and ul
I recommend you reset, and then try to style.
RESET:
ul {
margin: 0;
padding: 0;
}
TARGET RE-STYLE:
.nav {
margin: /* your style here */;
padding: /* your style here */;
}
A: This
.nav ul li{
width: 100%;
}
is saying :
*
*an element with class .nav
*with a descendant of type ul
*with a descendant of type li
Since .nav is a class of your ul, and not of an ancestor of your ul, you should use
ul.nav li {
width: 100%;
}
that instead means :
*
*an element of type ul with class .nav
*with a descendant of type li
EDIT: for the margin problem, you should probably use position: relative; instead of position: absolute;, that should not be used if not completely aware of how it works | unknown | |

d5781 | train | Editing XML in AS3 is actually pretty easy and pretty basic - it's a core part of AS3. AS3 automatically adds nodes as you call them, like so:
var xml:XML = <data />;
xml.player.money = 15831;
xml.player.shiptype = 1;
xml.player.ship.fuelCur = 450;
Will result in:
<data>
<player>
<money>15831</money>
<shiptype>1</shiptype>
<ship>
<fuelCur>450</fuelCur>
</ship>
</player>
</data>
Then to add multiples of the same node, just start a new XML object of the type you want, and append it to the XML object you're working on. Or skip the separate xml object entirely. Repeat as many times as needed:
var segment:XML = <planet />;
xml.appendChild(segment); // xml.planet[0]
xml.appendChild(segment); // xml.planet[1]
xml.appendChild(<planet />); // xml.planet[2]
//etc...
Then you can add values to them by their indexes.
//Assuming this is the 4th planet you've added...
xml.planet[3].population = 29827632;
A: In FlashDevelop, try creating a separate XML file entirely. That will give you better code prompting.
For XML, though, I have found that Adobe's rudimentary docs on their XML class has a wealth of useful examples and tools for creating and using XML objects. | unknown | |

d5783 | train | Linq way:
int min = 3;
int max = 10;
int increments = 15;
Enumerable
.Range(min, max - min + 1)
.Concat(Enumerable
.Range(min, max - min + 1)
.Reverse()
.Skip(increments % 2))
.ToArray();
A: This should work:
public static IEnumerable<decimal> NewMethod(decimal min, decimal max, int count)
{
var increment = (max - min) / (int)((count - 1) / 2);
for (var i = min; i < max; i += increment)
yield return i;
if (count % 2 == 0)
yield return max;
for (var i = max; i >= min ; i -= increment)
yield return i;
}
Sample test:
var min = 3.0m;
var max = 10.0m;
var count = 16;
MessageBox.Show(string.Join(", ", NewMethod(min, max, count)));
Edit: You have to cope with floating point types losing precision, otherwise you will be missing an element in the final result set. Tinker a bit with Math.Round over the i += and i -= part, that's up to you. I have updated code to replace double with more reliable decimal type. But there is no guarantee this should not fail every time. Easier is to avoid cases where you will need decimal types in the result like { 1, 2.2, 3.4 } etc.
A: Here's a one-way ramp that handles floating point values correctly. You should be able to modify it to make a triangle waveform. When implementing a ramp, care must be taken to make sure not to accumulate either round-off errors, or off-by-one errors for various inputs.
void Packet::SetRamp( const SampleType start /*= Signal::One*/,
const SampleType finish /*= -Signal::One */ )
{
SampleType slope, current;
SampleOffsetType len;
len = GetLength();
if ( len < 2 )
throw std::range_error( "packet is not large enough to set ramp into" );
slope = ( finish - start ) / ( len - 1 );
for ( SampleOffsetType row = 0; row < len; row++ )
{
current = slope * row + start;

try (ZipFile zipFile = new ZipFile(path, StandardCharsets.UTF_8)) {
zipFile.stream()
.forEachOrdered(entry -> System.out.printf("- %s%n", entry.getName()));
} catch (IOException e) {
e.printStackTrace();
}
However the zip does not has added the encoding (as bytes[] extra information).
Three solutions would be imaginable:
*
*One short solution might be to run TomCat under a UTF-8 locale.
*The best would be to have maven build a war with UTF-8 encoding. (<onfiguration><encoding>UTF-8</encoding></configuration>)
*Repairing the war by converting it.
With the first two solutions I have no experience. A quick search didn't yield anything ("encoding" is a bit ubiquitous).
The repair code is simple:
Path path = Paths.get(".../api.war").toAbsolutePath().normalize();
Path path2 = Paths.get(".../api2.war").toAbsolutePath().normalize();
URI uri = URI.create("jar:file://" + path.toString());
Map<String,String> env = new HashMap<String,String>();
env.put("create", "false");
env.put("encoding", "UTF-8");
URI uri2 = URI.create("jar:file://" + path2.toString());
Map<String,String> env2 = new HashMap<String,String>();
env2.put("create", "true");
env2.put("encoding", "UTF-8");
try (FileSystem zipFS = FileSystems.newFileSystem(uri, env);
FileSystem zipFS2 = FileSystems.newFileSystem(uri2, env2)) {
Files.walkFileTree(zipFS.getPath("/"), new SimpleFileVisitor<Path>() {
@Override
public FileVisitResult visitFile(Path file, BasicFileAttributes attrs)
throws IOException {
System.out.println("* File: " + file);
Path file2 = zipFS2.getPath(file.toString());
Files.createDirectories(file2.getParent());
Files.copy(file, file2);
return FileVisitResult.CONTINUE;
}
});
} catch(IOException e) {
e.printStackTrace();

d5789 | train | Adding the field:
@Id private String id;
to my model seems to have resolved the issue. | unknown | |
d5790 | train | First of all, serializer fields with (many=True) create nested objects.
If you input data with Rooms as already serialized, then it means that you create other Rooms instances. It will be shown with if module_serializer.is_valid(): part. Therefore, if you intended to implement as just link already instantiated Rooms to Module, it's better to make it as primary key list.
Here are my example codes.
class ModuleSerializer(serializers.ModelSerializer):
rooms = RoomSerializer(many=True, read_only=True)
def create(self, validated_data):
rooms_data = validated_data['room_list']
module = Module.objects.create(**validated_data)
for data in rooms_data.split(' '):
room = Rooms.objects.get(room_id=data)
module.rooms.add(room)
return module
def update(self, instance, validated_data):
# Updating rooms
rooms_data = validated_data.get('rooms')
instance.rooms.clear()
for room_data in rooms_data:
room = Rooms.objects.get(**room_data)
instance.rooms.add(room)
# Updating other fields
fields = [
'title',
'desc',
'thumbnail',
'is_deleted',
]
for field in fields:
setattr(instance, field, validated_data[field])
instance.save()
return instance
class Meta:
model = Module
fields = '__all__'
class AddModule(APIView):
def post(self, request, format=None):
# creating the module
module_serializer = ModuleSerializer(data=request.data)
if module_serializer.is_valid():
module_serializer.save()
return Response(module_serializer.data['module_id'])
return Response(module_serializer.errors)

d5791 | train | context.times is an array containing activities, right? Well, in javascript, .length of an array represents the length of the array itself, so it represents how many activities you have. Javascript has no way to know what you're trying to sum or achieve.
You need to sum the durations yourself by iterating the array of activities, so you need to have:
const TimeTotal = ({ time }) => {
const context = useContext(TimeContext);
let totalDuration = 0;
context.times.forEach((entry) => {
totalDuration += entry.time;
});
return <div className="time-total">Total: {totalDuration}</div>
}
A shorter version would be:
const context = useContext(TimeContext);
const totalDuration = context.times.reduce((total, entry) => entry.time + total, 0)
const TimeTotal = ({ time }) => {
const context = useContext(TimeContext)l
const totalDuration = context.times.reduce((total, entry) => entry.time + total, 0);
return <div className="time-total">Total: {totalDuration}</div>
}
You can read more about reduce here.
A: You can use .reduce() method of Array, something like
const timesSum = context.times.reduce((acc, {time}) => {
return acc + time
}, 0)
Take into account that I assumed time as numeric type. In real life you may need to cast time to number on manipulate it's value the way you need. Maybe you'll have to format timesSum.
Finally you'll have something like:
const TimeTotal = ({ time }) => {
const context = useContext(TimeContext)
console.log(context)
const timesSum = context.times.reduce((acc, {time}) => {
return acc + time
}, 0);
return <div className="time-total">Total: {timesSum}</div>

d5792 | train | Use a JavaScript Modal popup! eg. JQuery UI Modal Popup
A: its a browser property for the client,if he doesnt want to view these alerts. you cant remove that check box and message.
if this message is shown then what the problem, leave it for the user.
why you want to force him to view these alerts,
it must be user's wish to see or not see these alerts.
for better user experience and for your purpose you can use fancybox or facebox
fancy box fiddler check this http://jsfiddle.net/BJNYr/
A: This is a browser matter, so you as a developer cant do anything with that behavior.
Here is a similar question
already answered here
A: unfortunately you can't be sure that user has his browser settings with javascript alerts popup on ( that called with 'alert('...') function').
You should use javascript dialog plygin instead.
For example:

d5793 | train | No, that's not a problem. It means that your objects come and go - you create them in scope, use them, and then they're eligible for GC. I don't think that's an indication that something's wrong.
The other extreme would be an issue: objects are created, age, and stick around too long. That's where memory leaks and filled perm space happens.
A: I think you do have a problem here.
I'm not an expert on reading GC logs, but I think it is saying that you have a 'young' space of 76672K, and a total heap size of 11525824K. Furthermore, the total heap usage after each GC cycle is 10765868K ... and growing. And it is (apparently) spending ~30% of its time garbage collecting.
My diagnosis is that your heap is nearly full, and you are spending a significant (and increasing) percentage of time garbage collection as a direct result.
My advice would be restart the application (short term), and look for memory leaks (long term). If there are no memory leaks (i.e. your application is using all of that heap space) then you need to look for ways to reduce you application's memory usage.
Your application does seem to be generating a fair bit of garbage, but that is not necessarily a worry. The HotSpot GCs can reclaim garbage pretty efficiently. It is the amount of non-garbage that it has to deal with that causes performance issues. | unknown | |
d5794 | train | I need a way of determining which particular class of the 5 classes called the IntentService, so the appropriate action is taken.
Put an extra on the Intent that you pass to startActivity() that indicates what the IntentService should do. You get a copy of that Intent in onHandleIntent() in the IntentService, so you can retrieve the extra and take appropriate steps based upon its value.
A: At the top of the activity I add:-
private final static String THIS_ACTIVITY = "AddProductToShopActivity";
for the intent I add:
intent.putExtra("CALLER", THIS_ACTIVITY);
In the started activity :-
final String caller = getIntent().getStringExtra("Caller"); | unknown | |

d5796 | train | Yes this is absolutely possible. The less files just get compiled into css in the pub directory. To add your own static css files you will just put them in your css directory (/app/design/frontend/{vendor}/{theme}/web/css) and they will be accessed just like any less compiled css file.
Depending on your magento configuration you may need to first run bin/magento setup:static-content:deploy from your magento installation's root directory. | unknown | |
d5797 | train | The fastest way I usually do this is using find > replace...
Do something like this:
*
*Select the cells that have the formulas you want
*Use the find > replace feature in excel and replace all = with some other, unused character (I usually use #) - This will change them from formulas to plain text
*Copy those cells and paste them where you want
*Use the find > replace feature to replace that other character back to =
In effect, you are changing the formula to text, copying and pasting it as the plain text (so preserving the cell references), then changing it back to the original formula.
Hope this helps and makes sense. | unknown | |
d5798 | train | in your code, you have created from HardwareDetailApp in two place, in every creation of that you must set the same property with same order.
for example if in linq to entity you Select something like:
Place1:
...
Select new MyClass()
{
PropA: 1,
}
...
and in that query you need to another Select from MyClass but with some other properties like PropB, Like:
Place2:
...
Select new MyClass()
{
PropB: 2,
}
...
you must change all Select from MyClass into same, and set the properties you dont need to them, to its default, and set the properties in same order like:
Place1:
...
Select new MyClass()
{
PropA: 1,
PropB: default(int),
}
...
and
Place2:
...
Select new MyClass()
{
PropA: default(int),
PropB: 2,
}
...
my codes are in c#..
in this part of your code Dim Data = (From p In DB.TT_HARDW .... try to set Firmware and SerialNum at first like the second select, (i have not checked other properties carefully) | unknown | |
d5799 | train | If you don't want to add a scroll bar, and you don't want to rearrange the widgets, then the only options left are
*
*Lay the items out on more than one window (two pages for example).
*Change the scaling of the items (shrink them)
There is not an infinite number of approaches. The more approaches you decide are unsuitable will limit the opportunities to address the key issues. In your case, you have two dramatically different screen layouts, the obvious solution would be to detect the screen parameters, and select one of two different layouts, each tailored to look good.
A: Too much controls in a window is much boring. So why don't you categorize the controls and add them in different tabs using JTabbedPane ?
A: I think this is more suitable. If this is not desired, then adding a scroll pane would be better. Well shrinking the controls may not be that helpful | unknown | |
d5800 | train | You misunderstood the way Random is used: it is not a number, it is a class that can be used to generate random numbers.
Try this:
// Make a generator
Random gen = new Random();
// Now we can use our generator to make new random numbers like this:
int num1 = gen.Next();
int num2 = gen.Next();
Every time you call gen.Next() you get a new random number. If you would like the sequence of random numbers to be repeatable, pass a number (any number) to the constructor of the Random. Beware that every time you run your program the result will stay the same.
A: There are quite a few issues with the code snippet you pasted. I'd suggest (if you haven't already) investing in a decent beginning C# book. Generating random numbers, in fact, is one of the most popular "example programs" you find in those kinds of books. However, to get you started, here's some key points:
*
*When you paste sample code to a site like this, make sure it is a short, self-contained, correct example. Even if we fix the compiler error in your code, there are several other issues with it, including unbalanced and/or missing braces. Start simple and build your example up until you get the error, then paste that code. Note that a good 75% of the time this will help you fix the error yourself. For example, if you removed the lines of code that did not compile, and just ran the first part, it would print out "What is System.Random - System.Random?", which should give you a pretty clear idea that your num1 and num2 are not what you thought they were.
*As the rest of the answers here have pointed out, you have a fundamental misunderstanding of how the C# Random class works. (Don't feel bad, computer-generated "random numbers" make no sense to anyone until someone explains them to you.) The solution provided in those answers is correct: Random is a random number generator, and you need to call one of the Next functions on your instance to get an integer from it. Also, you usually will not want multiple instances of Random unless you actually want to produce the same random sequence more than once. The MSDN article has a very thorough example.
*While not "wrong" per-se, you're not being very efficient with your console output. Console's read and write functions operate entirely on string objects, and they have built-in composite formatting capabilities. For example, your first few lines of code could be rewritten as:
var random = new Random();
var x = random.Next();
var y = random.Next();
Console.Write("What is {0} + {1}? ", x, y);
*As I mentioned in my comment, Console.Read() is not the correct function to read in complete user input; it returns data a single UTF-16 character at a time. For example, if the user typed in 150 you would get 49, 53, and 48, in that order. Since you presumably want to allow the user to type in more than one digit at a time, you should instead called Console.ReadLine(), which returns the entire string, then convert that to an integer using Int32.Parse() or some similar function.
A: You are trying to add two random generators not random numbers, use this:
Random randomGenerator = new Random(0);
var num1 = randomGenerator.Next();
var num2 = randomGenerator.Next();
A: You need to call one of the overloads of Random.Next() http://msdn.microsoft.com/en-us/library/9b3ta19y.aspx to get the actual random number. | unknown |
