I mostly prefer Criteria Queries for dynamic queries. For example it is much easier to add some ordering dynamically or leave some parts (e.g. restrictions) out depending on some parameter.

On the other hand I'm using HQL for static and complex queries, because it's much easier to understand/read HQL. Also, HQL is a bit more powerful, I think, e.g. for different join types.

To change the directory for target dll/exe, use this in your pro file:

CONFIG(debug, debug|release) {
    DESTDIR = build/debug
} else {
    DESTDIR = build/release
}

You might also want to change directories for other build targets like object files and moc files (check qmake variable reference for details or qmake CONFIG() function reference).

Can also be called as

@Html.Partial("_PartialView", (ModelClass)View.Data)

Unexpected reason: # character in file path

Due to some internal bug, the error Content is not allowed in prolog also appears if the file content itself is 100% correct but you are supplying the file name like C:\Data\#22\file.xml.

This may possibly apply to other special characters, too.

How to check: If you move your file into a path without special characters and the error disappears, then it was this issue.

You need to use custom comparator which will use compareToIgnoreCase, not compareTo.

I prefer use a pure MySQL syntax to get last auto_increment id of the table I want.

php mysql_insert_id() and mysql last_insert_id() give only last transaction ID.

If you want last auto_incremented ID of any table in your schema (not only last transaction one), you can use this query

SELECT AUTO_INCREMENT FROM information_schema.TABLES
    WHERE TABLE_SCHEMA = 'my_database' 
    AND TABLE_NAME = 'my_table_name';

That's it.

MaxLength is used for the Entity Framework to decide how large to make a string value field when it creates the database.

From MSDN:

Specifies the maximum length of array or string data allowed in a property.

StringLength is a data annotation that will be used for validation of user input.

From MSDN:

Specifies the minimum and maximum length of characters that are allowed in a data field.

Using the type="image" is problematic because the ability to pass a value is disabled. Although it's not as customizable and thus as pretty, you can still use your images ao long as they are part of a type="button".

<button type="submit" name="someName" value="someValue"><img src="someImage.png" alt="SomeAlternateText"></button>

You can create a utility class to check if the class represents any Collection, Map or Array

  public static boolean isCollection(Class<?> rawPropertyType) {
        return Collection.class.isAssignableFrom(rawPropertyType) || 
               Map.class.isAssignableFrom(rawPropertyType) || 
               rawPropertyType.isArray();
 }

raw_input is your helper here. From documentation -

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

So your code will basically look like this.

num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
    n = raw_input("num :")
    num_array.append(int(n))
print 'ARRAY: ',num_array

P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input does not do any type checking, so you need to be careful...

if 'seek' in 'those who seek shall find':
    print('Success!')

but keep in mind that this matches a sequence of characters, not necessarily a whole word - for example, 'word' in 'swordsmith' is True. If you only want to match whole words, you ought to use regular expressions:

import re

def findWholeWord(w):
    return re.compile(r'\b({0})\b'.format(w), flags=re.IGNORECASE).search

findWholeWord('seek')('those who seek shall find')    # -> <match object>
findWholeWord('word')('swordsmith')                   # -> None

choicely, you could use a your Folder/index.cshtml as a masterpage then add section scripts. Then, in your layout you have:

@RenderSection("scripts", required: false) 

and your index.cshtml:

@section scripts{
     @Scripts.Render("~/Scripts/file.js")
}

and it will working over all your partialviews. It work for me

According to this Video if you use the ProGuard you don't need even think about Enums performance issues!!

Proguard can in many situations optimize Enums to INT values on your behalf so really don't need to think about it or do any work.

If you have access to the NgModelController (you can only get access to it from a directive) then you can call

ngModel.$setViewValue("your new view value");
// or to keep the view value the same and just change it to dirty
ngModel.$setViewValue(ngModel.$viewValue);

Probably not the case of everybody but I had the same problem. I was using the last, in my case, the error was because I was using jfrog manage from the company where I am working.

 npm config list

The result was

; cli configs
metrics-registry = "https://COMPANYNAME.jfrog.io/COMPANYNAM/api/npm/npm/"
scope = ""
user-agent = "npm/6.3.0 node/v8.11.2 win32 x64"

; userconfig C:\Users\USER\.npmrc
always-auth = true
email = "XXXXXXXXX"
registry = "https://COMPANYNAME.jfrog.io/COMPANYNAME/api/npm/npm/"

; builtin config undefined

; node bin location = C:\Program Files\nodejs\node.exe
; cwd = C:\WINDOWS\system32
; HOME = C:\Users\XXXXXX
; "npm config ls -l" to show all defaults.

I solve the problem by using the global metrics.

You can do this easily by adding a Timer to your form (from the designer) and setting it's Tick-function to run your isonline-function.

Try the following line:

while read line1; do read line2; echo "$line1 $line2"; done <old.txt>new_file

Put delimiter in-between

"$line1 $line2";

e.g. if the delimiter is |, then:

"$line1|$line2";

I'm not sure about the circumstances where you need to convert an NSInteger to an int.

NSInteger is just a typedef:

NSInteger Used to describe an integer independently of whether you are building for a 32-bit or a 64-bit system.

#if __LP64__ || TARGET_OS_EMBEDDED || TARGET_OS_IPHONE || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64 
typedef long NSInteger;
#else
typedef int NSInteger;
#endif

You can use NSInteger any place you use an int without converting it.

Descending order using underscore can be done by multiplying the return value by -1.

//Ascending Order:
_.sortBy([2, 3, 1], function(num){
    return num;
}); // [1, 2, 3]


//Descending Order:
_.sortBy([2, 3, 1], function(num){
    return num * -1;
}); // [3, 2, 1]

If you're sorting by strings not numbers, you can use the charCodeAt() method to get the unicode value.

//Descending Order Strings:
_.sortBy(['a', 'b', 'c'], function(s){ 
    return s.charCodeAt() * -1;
});

For agg, the lambba function gets a Series, which does not have a 'Short name' attribute.

stats.mode returns a tuple of two arrays, so you have to take the first element of the first array in this tuple.

With these two simple changements:

source.groupby(['Country','City']).agg(lambda x: stats.mode(x)[0][0])

returns

                         Short name
Country City                       
Russia  Sankt-Petersburg        Spb
USA     New-York                 NY

This is the strict aliasing rule, found in section 3.10 of the C++03 standard (other answers provide good explanation, but none provided the rule itself):

If a program attempts to access the stored value of an object through an lvalue of other than one of the following types the behavior is undefined:

• the dynamic type of the object,
• a cv-qualified version of the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,
• an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union),
• a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,
• a char or unsigned char type.

C++11 and C++14 wording (changes emphasized):

If a program attempts to access the stored value of an object through a glvalue of other than one of the following types the behavior is undefined:

• the dynamic type of the object,
• a cv-qualified version of the dynamic type of the object,
• a type similar (as defined in 4.4) to the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,
• an aggregate or union type that includes one of the aforementioned types among its elements or non-static data members (including, recursively, an element or non-static data member of a subaggregate or contained union),
• a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,
• a char or unsigned char type.

Two changes were small: glvalue instead of lvalue, and clarification of the aggregate/union case.

The third change makes a stronger guarantee (relaxes the strong aliasing rule): The new concept of similar types that are now safe to alias.

Also the C wording (C99; ISO/IEC 9899:1999 6.5/7; the exact same wording is used in ISO/IEC 9899:2011 §6.5 ¶7):

An object shall have its stored value accessed only by an lvalue expression that has one of the following types ^{73) or 88)}:

• a type compatible with the effective type of the object,
• a quali?ed version of a type compatible with the effective type of the object,
• a type that is the signed or unsigned type corresponding to the effective type of the object,
• a type that is the signed or unsigned type corresponding to a quali?ed version of the effective type of the object,
• an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union), or
• a character type.

^{73) or 88)} The intent of this list is to specify those circumstances in which an object may or may not be aliased.

You can use templates.

template <typename T> const char* typeof(T&) { return "unknown"; }    // default
template<> const char* typeof(int&) { return "int"; }
template<> const char* typeof(float&) { return "float"; }

In the example above, when the type is not matched it will print "unknown".

It sounds like the only varaible stored in the .RData file was one named isfar.

Are you really sure that you saved the table? The command should have been:

save(the_table, file = "isfar.RData")

There are many ways to examine a variable.

Type it's name at the command prompt to see it printed. Then look at str, ls.str, summary, View and unclass.

In codeigniter there is no need to sennd "data" in ajax post method.. here is the example .

   searchThis = 'This text will be search';
    $.ajax({
      type: "POST",
      url: "<?php echo site_url();?>/software/search/"+searchThis,
      dataType: "html",
      success:function(data){
        alert(data);
      },

    });

Note : in url , software is the controller name , search is the function name and searchThis is the variable that i m sending.

Here is the controller.

    public function search(){
    $search = $this->uri->segment(3);
      echo '<p>'.$search.'</p>';
    }

I hope you can get idea for your work .

I was getting this error message due to my EC2 instance's clock being out of sync.

I was able to fix on Ubuntu using this:

sudo ntpdate ntp.ubuntu.com
sudo apt-get install ntp

You can do this by 2 options:

Option 1: By setting its xml attributes

 `android:textOff="TEXT OFF"
  android:textOn="TEXT ON"`

Option 2: Programmatically

Set the attribute onClick: methodNameHere (mine is toggleState) Then write this code:

public void toggleState(View view) {
   boolean toggle = ((ToogleButton)view).isChecked();
   if (toggle){
       ((ToogleButton)view).setTextOn("TEXT ON");
   } else {
      ((ToogleButton)view).setTextOff("TEXT OFF");
   }
}

PS: it works for me, hope it works for you too

Since you mentioned ng-src and it seems as though you want the page to finish rendering before loading your image, you may modify jaime's answer to run the native directive after the browser finishes rendering.

This blog post explains this pretty well; essentially, you insert the $timeout wrapper for window.setTimeout before the callback function wherein you make those modifications to the CSS.

gradle com.android.tools.build:gradle:2.2.0-alpha6

constraint layout dependency com.android.support.constraint:constraint-layout:1.0.0-alpha4

works for me

getdate() or getutcdate().

This post already has a checked answer, but the answer doesn't filter for null values. The correct answer should prevent null values by using the Object::nonNull function as a predicate.

BigDecimal result = invoiceList.stream()
    .map(Invoice::total)
    .filter(Objects::nonNull)
    .filter(i -> (i.getUnit_price() != null) && (i.getQuantity != null))
    .reduce(BigDecimal.ZERO, BigDecimal::add);

This prevents null values from attempting to be summed as we reduce.

Yes, you can access a form in the controller (as stated in the docs).

Except when your form is not defined in the controller scope and is defined in a child scope instead.

Basically, some angular directives, such as ng-if, ng-repeat or ng-include, will create an isolated child scope. So will any custom directives with a scope: {} property defined. Probably, your foundation components are also in your way.

I had the same problem when introducing a simple ng-if around the <form> tag.

See these for more info:

• https://groups.google.com/forum/#!topic/angular/B2uB8-9_Xbk

• AngularJS - losing scope when using ng-include

Note: I suggest you re-write your question. The answer to your question is yes but your problem is slightly different:

Can I access a form in a child scope from the controller?

To which the answer would simply be: no.

This documents explains:

(Search for generate204)

Relevant section:

Among the different objects, a javascript function triggers a generate204 request sent to the video server that is supposed to serve the video. This starts the video prefetch, which has two main goals: first, it forces the client to perform the DNS resolution of the video server name. Second, it forces the client to open a TCP connection toward the video server. Both help to speed-up the video download phase.

In addition, the generate204 request has exactly the same format and options of the real video download request, so that the video server is eventually warned that a client will possibly download that video very soon. Note that the video server replies with a 204 No Content response, as implied by the command, and no video content is downloaded so far.

I believe I found the solution in the jQuery documentation:

Animates all paragraph to a left style of 50 and opacity of 1 (opaque, visible), completing the animation within 500 milliseconds. It also will do it outside the queue, meaning it will automatically start without waiting for its turn.

$( "p" ).animate({
  left: "50px", opacity: 1
}, { duration: 500, queue: false }); 

simply add: queue: false.

You need to give the body and the html a height too. Otherwise, the body will only be as high as its contents (the single div), and 50% of that will be half the height of this div.

What actually was missing for me and what made it work then was downloading'Google Play services' and 'Google Repository'

Go to: Settings -> Android SDK -> SDK Tools -> check/install Google Play services + repository

Hope it helps.

Here is a good description written about node modules in node.js in action book from Manning publication.
What ultimately gets exported in your application is module.exports.
exports is set up simply as a global reference to module.exports , which initially is defined as an empty object that you can add properties to. So exports.myFunc is just shorthand for module.exports.myFunc.

As a result, if exports is set to anything else, it breaks the reference between module.exports and exports . Because module.exports is what really gets exported, exports will no longer work as expected—it doesn’t reference module .exports anymore. If you want to maintain that link, you can make module.exports reference exports again as follows:

module.exports = exports = db;

You can go for recursive approach:

Here is the pseudo code:

Node* reverse(Node* root)
{
    if(!root) return NULL;

    if(!(root->next)) temp = root;
    else
    {
        reverse(root->next);
        root->next->next = root;
        root->next = NULL;
    }

    return temp;
}

After the call is made to the function, it returns the new root[temp] of the linked list. As it is very clear that it makes use of only two pointers.

For GlassFish Jersey JAX-RS implementation I have resolved this issue by common method is describing all common parameters. At least three of parameters have to be equal: name(="name"), path(="/") and domain(=null) :

public static NewCookie createDomainCookie(String value, int maxAgeInMinutes) {
    ZonedDateTime time = ZonedDateTime.now().plusMinutes(maxAgeInMinutes);
    Date expiry = time.toInstant().toEpochMilli();
    NewCookie newCookie = new NewCookie("name", value, "/", null, Cookie.DEFAULT_VERSION,null, maxAgeInMinutes*60, expiry, false, false);
    return newCookie;
}

And use it the common way to set cookie:

NewCookie domainNewCookie = RsCookieHelper.createDomainCookie(token, 60);
Response res = Response.status(Response.Status.OK).cookie(domainNewCookie).build();

and to delete the cookie:

NewCookie domainNewCookie = RsCookieHelper.createDomainCookie("", 0);
Response res = Response.status(Response.Status.OK).cookie(domainNewCookie).build();

This will help you. DateFormat df = new SimpleDateFormat("dd/MM/yyyy"); print (df.format(new Date());

var data = [
    {
        id : "001",
        name : "apple",
        category : "fruit",
        color : "red"
    },
    {
        id : "002",
        name : "melon",
        category : "fruit",
        color : "green"
    },
    {
        id : "003",
        name : "banana",
        category : "fruit",
        color : "yellow"
    }
];

for(var i = 0, len = data.length; i < length; i++) {
    var temp = '<tr><td>' + data[i].id + '</td>';
    temp+= '<td>' + data[i].name+ '</td>';
    temp+= '<td>' + data[i].category + '</td>';
    temp+= '<td>' + data[i].color + '</td></tr>';
    $('table tbody').append(temp));
}

Docker caches the entire filesystem state after each successful RUN line.

Knowing that:

• to examine the latest state before your failing RUN command, comment it out in the Dockerfile (as well as any and all subsequent RUN commands), then run docker build and docker run again.
• to examine the state after the failing RUN command, simply add || true to it to force it to succeed; then proceed like above (keep any and all subsequent RUN commands commented out, run docker build and docker run)

Tada, no need to mess with Docker internals or layer IDs, and as a bonus Docker automatically minimizes the amount of work that needs to be re-done.

To create both of the created_at and updated_at columns:

$t->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));
$t->timestamp('updated_at')->default(DB::raw('CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP'));

You will need MySQL version >= 5.6.5 to have multiple columns with CURRENT_TIMESTAMP

Try this

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.merge.html

left_on : label or list, or array-like Field names to join on in left DataFrame. Can be a vector or list of vectors of the length of the DataFrame to use a particular vector as the join key instead of columns

right_on : label or list, or array-like Field names to join on in right DataFrame or vector/list of vectors per left_on docs

For security reasons, the shell will not search the current directory (by default) for an executable. You have to be specific, and tell bash that your script is in the current directory (.):

$ ./MigrateNshell.sh

It will prints the string"something" three times.

JLabel[] labels = {new JLabel(), new JLabel(), new JLabel()};                   

for ( JLabel label : labels )                  
 {              
   label.setText("something");  

 panel.add(label);             
 }

this is the FASTEST (most readable, least complicated) way to do it, Owens works but it's not legal HTML, technically this answer is not jQuery (but since jQuery is a pre-prepared pseudocode - reinterpreted on the client platform as native JavaScript - there really is no such thing as jQuery anyway)

 <button onclick="window.location.href='http://www.google.com';">Google</button>

A unit test tests code that you have complete control over whereas an integration test tests how your code uses or "integrates" with some other code.

So you would write unit tests to make sure your own libraries work as intended, and then write integration tests to make sure your code plays nicely with other code you are making use of, for instance a library.

Functional tests are related to integration tests, but refer more specifically to tests that test an entire system or application with all of the code running together, almost a super integration test.

Use aggregation function and $project to get specific object field in document

db.getCollection('geolocations').aggregate([ { $project : { geolocation : 1} } ])

I faced the same error posted by OP while trying to debug my ASP.NET website using IIS Express server. IIS Express is used by Visual Studio to run the website when we press F5.

Open solution explorer in Visual Studio -> Expand the web application project node (StudentInfo in my case) -> Right click on the web page which you want to get loaded when your website starts(StudentPortal.aspx in my case) -> Select Set as Start Page option from the context menu as shown below. It started to work from the next run.

Root cause: I concluded that the start page which is the default document for the website wasn't set correctly or had got messed up somehow during development.

Updated 2017-12-16

I was not sure about the tests in OP. I decided to experiment a little and ended up busting some of the myths.

Synchronous <script src...> will block downloading of the resources below it until it is downloaded and executed

This is no longer true. Have a look at the waterfall generated by Chrome 63:

<head>
<script src="//alias-0.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=1"></script>
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=2"></script>
<script src="//alias-2.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=3"></script>
</head>

<link rel=stylesheet> will not block download and execution of scripts below it

This is incorrect. The stylesheet will not block download but it will block execution of the script (little explanation here). Have a look at performance chart generated by Chrome 63:

<link href="//alias-0.redacted.com/payload.php?type=css&amp;delay=666" rel="stylesheet">
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;block=1000"></script>

Keeping the above in mind, the results in OP can be explained as follows:

For your example, Dirk's answer is perfect. If you instead had a data frame and wanted to add that sort of sequence as a column, you could also use group from groupdata2 (disclaimer: my package) to greedily divide the datapoints into groups.

# Attach groupdata2
library(groupdata2)
# Create a random data frame
df <- data.frame("x" = rnorm(27))
# Create groups with 5 members each (except last group)
group(df, n = 5, method = "greedy")
         x .groups
     <dbl> <fct>  
 1  0.891  1      
 2 -1.13   1      
 3 -0.500  1      
 4 -1.12   1      
 5 -0.0187 1      
 6  0.420  2      
 7 -0.449  2      
 8  0.365  2      
 9  0.526  2      
10  0.466  2      
# … with 17 more rows

There's a whole range of methods for creating this kind of grouping factor. E.g. by number of groups, a list of group sizes, or by having groups start when the value in some column differs from the value in the previous row (e.g. if a column is c("x","x","y","z","z") the grouping factor would be c(1,1,2,3,3).

Python 2:

with open("datafile") as myfile:
    head = [next(myfile) for x in xrange(N)]
print head

Python 3:

with open("datafile") as myfile:
    head = [next(myfile) for x in range(N)]
print(head)

Here's another way (both Python 2 & 3):

from itertools import islice

with open("datafile") as myfile:
    head = list(islice(myfile, N))
print(head)

Yor $.post has no data. You need to pass the form data. You can use serialize() to post the form data. Try this

$("#post-btn").click(function(){
    $.post("process.php", $('#reg-form').serialize() ,function(data){
        alert(data);
    });
});

Thowable catches really everything even ThreadDeath which gets thrown by default to stop a thread from the now deprecated Thread.stop() method. So by catching Throwable you can be sure that you'll never leave the try block without at least going through your catch block, but you should be prepared to also handle OutOfMemoryError and InternalError or StackOverflowError.

Catching Throwable is most useful for outer server loops that delegate all sorts of requests to outside code but may itself never terminate to keep the service alive.

unsorted_list.sort(key=lambda x: x[3])

Try to install it as a python package using pip as follows

$ sudo apt-get install python-scipy

If you want to run a python 3.x script, install scipy by:

$ pip3 install scipy
Otherwise install it by:
$ pip install scipy

I am using: Apache Commons Lang: StringUtils.ordinalIndexOf()

StringUtils.ordinalIndexOf("Java Language", "a", 2)

I found it useful to get a location of the library file with:

gem which *gemname*

Simpler way:

.then( resp=> {
  let resultFromDb= Object.values(resp)[0]
  console.log(resultFromDb)
}

In my example I received an object in response. When I use Object.values I have the value of the property as a response, however it comes inside an array, using [0] access the first index of this array, now i have the value to use it where I need it.

Simple and easy in javascipt

<script>

  document.getElementById("selectsearch").addEventListener("change", function(){

  var get_form =   document.getElementById("search-form") // get form 
  get_form.action =  '/search/' +  this.value; // assign value 

});

</script>

It acts as curly bracket. We have to keep the number of white spaces consistent through out the program.

Example 1:

def main():
     print "we are in main function"
     print "print 2nd line"

main()

Result:

We are in main function
print 2nd line

Example 2:

def main():
    print "we are in main function"
print "print 2nd line"

main()

Result:

print 2nd line
We are in main function

Here, in the 1st program, both the statement comes under the main function since both have equal number of white spaces while in the 2nd program, the 1st line is printed later because the main function is called after the 2nd line Note - The 2nd line has no white space, so it is independent of the main function.

In MySQL Workbench you can export the results of any single-table query as a list of INSERT statements. Just run the query, and then:

1. click on the floppy disk near Export/Import above the results
2. give the target file a name
3. at the bottom of the window, for Format select SQL INSERT statements
4. click Save
5. click Export

The first way would be preferred to the second.

This is because the header file will show that the parameter is optional and what its default value will be. Additionally, this will ensure that the default value will be the same, no matter the implementation of the corresponding .cpp file.

In the second way, there is no guarantee of a default value for the second parameter. The default value could change, depending on how the corresponding .cpp file is implemented.

Simply difference between Forward(ServletRequest request, ServletResponse response) and sendRedirect(String url) is

forward():

1. The forward() method is executed in the server side.
2. The request is transfer to other resource within same server.
3. It does not depend on the client’s request protocol since the forward () method is provided by the servlet container.
4. The request is shared by the target resource.
5. Only one call is consumed in this method.
6. It can be used within server.
7. We cannot see forwarded message, it is transparent.
8. The forward() method is faster than sendRedirect() method.
9. It is declared in RequestDispatcher interface.

sendRedirect():

1. The sendRedirect() method is executed in the client side.
2. The request is transfer to other resource to different server.
3. The sendRedirect() method is provided under HTTP so it can be used only with HTTP clients.
4. New request is created for the destination resource.
5. Two request and response calls are consumed.
6. It can be used within and outside the server.
7. We can see redirected address, it is not transparent.
8. The sendRedirect() method is slower because when new request is created old request object is lost.
9. It is declared in HttpServletResponse.

You can use this variable to retrieve response headers after file_get_contents() function.

Code:

  file_get_contents("http://example.com");
  var_dump($http_response_header);

Output:

array(9) {
  [0]=>
  string(15) "HTTP/1.1 200 OK"
  [1]=>
  string(35) "Date: Sat, 12 Apr 2008 17:30:38 GMT"
  [2]=>
  string(29) "Server: Apache/2.2.3 (CentOS)"
  [3]=>
  string(44) "Last-Modified: Tue, 15 Nov 2005 13:24:10 GMT"

  string(27) "ETag: "280100-1b6-80bfd280""
  [5]=>
  string(20) "Accept-Ranges: bytes"
  [6]=>
  string(19) "Content-Length: 438"
  [7]=>
  string(17) "Connection: close"
  [8]=>
  string(38) "Content-Type: text/html; charset=UTF-8"
}

You're the victim of the classic deadlock. task.Wait() or task.Result is a blocking call in UI thread which causes the deadlock.

Don't block in the UI thread. Never do it. Just await it.

private async void Button_Click(object sender, RoutedEventArgs 
{
      var task = GetResponseAsync<MyObject>("my url");
      var items = await task;
}

Btw, why are you catching the WebException and throwing it back? It would be better if you simply don't catch it. Both are same.

Also I can see you're mixing the asynchronous code with synchronous code inside the GetResponse method. StreamReader.ReadToEnd is a blocking call --you should be using StreamReader.ReadToEndAsync.

Also use "Async" suffix to methods which returns a Task or asynchronous to follow the TAP("Task based Asynchronous Pattern") convention as Jon says.

Your method should look something like the following when you've addressed all the above concerns.

public static async Task<List<T>> GetResponseAsync<T>(string url)
{
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
    var response = (HttpWebResponse)await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null);

    Stream stream = response.GetResponseStream();
    StreamReader strReader = new StreamReader(stream);
    string text = await strReader.ReadToEndAsync();

    return JsonConvert.DeserializeObject<List<T>>(text);
}

This also works fine .Simple and easy.see http://jsfiddle.net/uZc8w/570/

$('#myimage').removeAttr("click");

I've seen several answers and that's the only procedure that let me fix that without any conflicts.

If you want all changes from branch_new in branch_old, then:

git checkout branch_new
git merge -s ours branch_old
git checkout branch_old
git merge branch_new

once applied those four commands you can push the branch_old without any problem

The current best solution to this problem (referenced deep in https://github.com/kubernetes/kubernetes/issues/22368 linked in the sibling answer) is to use Deployments, and consider your ConfigMaps to be immutable.

When you want to change your config, create a new ConfigMap with the changes you want to make, and point your deployment at the new ConfigMap. If the new config is broken, the Deployment will refuse to scale down your working ReplicaSet. If the new config works, then your old ReplicaSet will be scaled to 0 replicas and deleted, and new pods will be started with the new config.

Not quite as quick as just editing the ConfigMap in place, but much safer.

You can detect which button (ok or cancel) pressed by user, because the onunload function called only when the user choise leaveing the page. Althoug in this funcion the possibilities is limited, because the DOM is being collapsed. You can run javascript, but the ajax POST doesn't do anything therefore you can't use this methode for automatic logout. But there is a solution for that. The window.open('logout.php') executed in the onunload funcion, so the user will logged out with a new window opening.

function onunload = (){
    window.open('logout.php');
}

This code called when user leave the page or close the active window and user logged out by 'logout.php'. The new window close immediately when logout php consist of code:

window.close();

Here are the two functions I use. They are based on matrix rotations. and can rotate around arbitrary axes. To rotate using the world's axes you would want to use the second function rotateAroundWorldAxis().

// Rotate an object around an arbitrary axis in object space
var rotObjectMatrix;
function rotateAroundObjectAxis(object, axis, radians) {
    rotObjectMatrix = new THREE.Matrix4();
    rotObjectMatrix.makeRotationAxis(axis.normalize(), radians);

    // old code for Three.JS pre r54:
    // object.matrix.multiplySelf(rotObjectMatrix);      // post-multiply
    // new code for Three.JS r55+:
    object.matrix.multiply(rotObjectMatrix);

    // old code for Three.js pre r49:
    // object.rotation.getRotationFromMatrix(object.matrix, object.scale);
    // old code for Three.js r50-r58:
    // object.rotation.setEulerFromRotationMatrix(object.matrix);
    // new code for Three.js r59+:
    object.rotation.setFromRotationMatrix(object.matrix);
}

var rotWorldMatrix;
// Rotate an object around an arbitrary axis in world space       
function rotateAroundWorldAxis(object, axis, radians) {
    rotWorldMatrix = new THREE.Matrix4();
    rotWorldMatrix.makeRotationAxis(axis.normalize(), radians);

    // old code for Three.JS pre r54:
    //  rotWorldMatrix.multiply(object.matrix);
    // new code for Three.JS r55+:
    rotWorldMatrix.multiply(object.matrix);                // pre-multiply

    object.matrix = rotWorldMatrix;

    // old code for Three.js pre r49:
    // object.rotation.getRotationFromMatrix(object.matrix, object.scale);
    // old code for Three.js pre r59:
    // object.rotation.setEulerFromRotationMatrix(object.matrix);
    // code for r59+:
    object.rotation.setFromRotationMatrix(object.matrix);
}

So you should call these functions within your anim function (requestAnimFrame callback), resulting in a rotation of 90 degrees on the x-axis:

var xAxis = new THREE.Vector3(1,0,0);
rotateAroundWorldAxis(mesh, xAxis, Math.PI / 180);

Seek to the end of the file and check the position:

 fseek(fileDescriptor, 0, SEEK_END);
 if (ftell(fileDescriptor) == 0) {
     // file is empty...
 } else {
     // file is not empty, go back to the beginning:
     fseek(fileDescriptor, 0, SEEK_SET);
 }

If you don't have the file open already, just use the fstat function and check the file size directly.

Perhaps you can use JavaScript to solve your cross-browser problem. It uses a different escape mechanism, one with which you're obviously already familiar:

(reference-to-the-tag).title = "Some \"text\"";

It doesn't strictly separate the functions of HTML, JavaScript, and CSS the way folks want you to nowadays, but whom do you need to make happy? Your users or techies you don't know?

First give your input type submit a name, like this name='submitform'.

and then put this in your php file

if (isset($_POST['submitform']))
    {   
    ?>
<script type="text/javascript">
window.location = "http://www.google.com/";
</script>      
    <?php
    }

Don't forget to change the url to yours.

res = request.GET['paymentid'] will raise a KeyError if paymentid is not in the GET data.

Your sample php code checks to see if paymentid is in the POST data, and sets $payID to '' otherwise:

$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''

The equivalent in python is to use the get() method with a default argument:

payment_id = request.POST.get('payment_id', '')

while debugging, this is what I see in the response.GET: <QueryDict: {}>, request.POST: <QueryDict: {}>

It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.

Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

It sounds like you're trying to use log4j from "both ends" (the consumer end and the configuration end).

If you want to code against the slf4j api but determine ahead of time (and programmatically) the configuration of the log4j Loggers that the classpath will return, you absolutely have to have some sort of logging adaptation which makes use of lazy construction.

public class YourLoggingWrapper {
    private static boolean loggingIsInitialized = false;

    public YourLoggingWrapper() {
        // ...blah
    }

    public static void debug(String debugMsg) {
        log(LogLevel.Debug, debugMsg);
    }

    // Same for all other log levels your want to handle.
    // You mentioned TRACE and ERROR.

    private static void log(LogLevel level, String logMsg) {
        if(!loggingIsInitialized)
            initLogging();

        org.slf4j.Logger slf4jLogger = org.slf4j.LoggerFactory.getLogger("DebugLogger");

        switch(level) {
        case: Debug:
            logger.debug(logMsg);
            break;
        default:
            // whatever
        }
    }

    // log4j logging is lazily constructed; it gets initialized
    // the first time the invoking app calls a log method
    private static void initLogging() {
        loggingIsInitialized = true;

        org.apache.log4j.Logger debugLogger = org.apache.log4j.LoggerFactory.getLogger("DebugLogger");

        // Now all the same configuration code that @oers suggested applies...
        // configure the logger, configure and add its appenders, etc.
        debugLogger.addAppender(someConfiguredFileAppender);
    }

With this approach, you don't need to worry about where/when your log4j loggers get configured. The first time the classpath asks for them, they get lazily constructed, passed back and made available via slf4j. Hope this helped!

$name -replace ";*",""

You were close, but you used the syntax of a wildcard expresson rather than a regular expression, which is what the -replace operator expects.

Therefore (hash sequence shortened):

PS> 'test.txt ; 131 136 80 89 119 17 60 123 210 121 188' -replace '\s*;.*'
test.txt

Note:

• Omitting the substitution-text operand (the 2nd RHS operand) implicitly uses "" (the empty string), i.e. it effectively removes what the regex matched.

• .* is what represents a potentially empty run (*) of characters (.) in a regex - it is the regex equivalent of * by itself in a wildcard expression.

• Adding \s* before the ; in the regex also removes trailing whitespace (\s) after the filename.

• I've used '...' rather than "..." to enclose the regex, so as to prevent confusion between what PowerShell expands up front (see expandable strings in PowerShell and what the .NET regex engine sees.

Just use this:

{{you_date_field|date:'Y-m-d'}}

This will show something like 2016-10-16. You can use the format as you want.

Note that solutions with timedelta.total_seconds() work on python-2.7+. Use calendar.timegm(future.utctimetuple()) for lower versions of Python.

Make the submit button the main image you are using. So the form tags would come first then submit button which is your only image so the image is your clickable image form. Then just make sure to put whatever you are passing before the submit button code.

when I try to run it, I get NoClassDefFoundError

Run it how? You're probably trying to run it with eclipse without having correctly imported your maven classpath. See the m2eclipse plugin for integrating maven with eclipse for that.

To verify that your maven config is correct, you could run your app with the exec plugin using:

mvn exec:java -D exec.mainClass=<your main class>

Update: First, regarding your error when running exec:java, your main class is tr.edu.hacettepe.cs.b21127113.bil138_4.App. When talking about class names, they're (almost) always dot-separated. The simple class name is just the last part: App in your case. The fully-qualified name is the full package plus the simple class name, and that's what you give to maven or java when you want to run something. What you were trying to use was a file system path to a source file. That's an entirely different beast. A class name generally translates directly to a class file that's found in the class path, as compared to a source file in the file system. In your specific case, the class file in question would probably be at target/classes/tr/edu/hacettepe/cs/b21127113/bil138_4/App.class because maven compiles to target/classes, and java traditionally creates a directory for each level of packaging.

Your original problem is simply that you haven't put the Jackson jars on your class path. When you run a java program from the command line, you have to set the class path to let it know where it can load classes from. You've added your own jar, but not the other required ones. Your comment makes me think you don't understand how to manually build a class path. In short, the class path can have two things: directories containing class files and jars containing class files. Directories containing jars won't work. For more details on building a class path, see "Setting the class path" and the java and javac tool documentation.

Your class path would need to be at least, and without the line feeds:

target/bil138_4-0.0.1-SNAPSHOT.jar:
/home/utdemir/.m2/repository/org/codehaus/jackson/jackson-core-asl/1.9.6/jackson-core-asl-1.9.6.jar:
/home/utdemir/.m2/repository/org/codehaus/jackson/jackson-mapper-asl/1.9.6/jackson-mapper-asl-1.9.6.jar

Note that the separator on Windows is a semicolon (;).

I apologize for not noticing it sooner. The problem was sitting there in your original post, but I missed it.

External return type declaration to use with multiple functions:

type ValidationReturnType = string | boolean;

function isEqual(number1: number, number2: number): ValidationReturnType {
    return number1 == number2 ? true : 'Numbers are not equal.';
}

I would like to propose the usage of string templates. Just place the string to be replaced in a dictionary and all is set! Example from docs.python.org

>>> from string import Template
>>> s = Template('$who likes $what')
>>> s.substitute(who='tim', what='kung pao')
'tim likes kung pao'
>>> d = dict(who='tim')
>>> Template('Give $who $100').substitute(d)
Traceback (most recent call last):
[...]
ValueError: Invalid placeholder in string: line 1, col 10
>>> Template('$who likes $what').substitute(d)
Traceback (most recent call last):
[...]
KeyError: 'what'
>>> Template('$who likes $what').safe_substitute(d)
'tim likes $what'

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...

I am using Xamarin.Android (MonoDroid), and I have requirments for developing UI Blocking confirm box. I am not going to argue with the client because I can see good reasons for why they want that (details here), so I need to implement this. I tried @Daniel and @MindSpiker above, but these did not work on MonoForAndroid, the moment the message is sent between the threads, the app is crashed. I assume it is something to do with Xamarin mapping.

I ended up creating a separate thread from the UI thread and then blocking that and waiting for the user response as follows:

// (since the controllers code is shared cross-platforms)
protected void RunConfirmAction(Action runnableAction)
{
    if (runnableAction != null)
    {
        if (Core.Platform.IsAndroid)
        {
            var confirmThread = new Thread(() => runnableAction());
            confirmThread.Start();
        }
        else
        {
            runnableAction();
        }
    }
}

// The call to the logout method has now changed like this:
RunConfirmAction(Logout);

// the implemtation of the MessageBox waiting is like this:
public DialogResult MessageBoxShow(string message, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton)
{
    if (_CurrentContext != null && _CurrentContext.Screen != null && MainForm.MainActivity != null)
    {
        Action<bool> callback = OnConfirmCallBack;
        _IsCurrentlyInConfirmProcess = true;
        Action messageBoxDelegate = () => MessageBox.Show(((Activity)MainForm.MainActivity), callback, message, caption, buttons);
        RunOnMainUiThread(messageBoxDelegate);
        while (_IsCurrentlyInConfirmProcess)
        {
            Thread.Sleep(1000);
        }               
    }
    else
    {
        LogHandler.LogError("Trying to display a Message box with no activity in the CurrentContext. Message was: " + message);
    }
    return _ConfirmBoxResult ? DialogResult.OK : DialogResult.No;

}

private void OnConfirmCallBack(bool confirmResult)
{
    _ConfirmBoxResult = confirmResult;
    _IsCurrentlyInConfirmProcess = false;
}

private bool _ConfirmBoxResult = false;
private bool _IsCurrentlyInConfirmProcess = false;

Full details on how to do this can be found in my blog post here

This is not right. Here's how you should use Runtime.exec(). You might also try its more modern cousin, ProcessBuilder:

Java Runtime.getRuntime().exec() alternatives

Try that

First place

global $var;
$var = 'value';

Second place

global $var;
if (isset($_POST['save_exit']))
{
    echo $var; 
}

Or if you want to be more explicit you can use the globals array:

$GLOBALS['var'] = 'test';

// after that
echo $GLOBALS['var'];

And here is third options which has nothing to do with PHP global that is due to the lack of clarity and information in the question. So if you have form in HTML and you want to pass "variable"/value to another PHP script you have to do the following:

HTML form

<form action="script.php" method="post">
    <input type="text" value="<?php echo $var?>" name="var" />
    <input type="submit" value="Send" />
</form>

PHP script ("script.php")

<?php

$var = $_POST['var'];
echo $var;

?>

The correct answer is usually to use require, but in a few cases it's not possible.

The following code will do the trick, but use it with care:

var fs = require('fs');
var vm = require('vm');
var includeInThisContext = function(path) {
    var code = fs.readFileSync(path);
    vm.runInThisContext(code, path);
}.bind(this);
includeInThisContext(__dirname+"/models/car.js");

Building on @Pvl's answer, you can include type safety on your returned value as well if you use overrides:

function dig<
  T,
  K1 extends keyof T
  >(obj: T, key1: K1): T[K1];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1]
  >(obj: T, key1: K1, key2: K2): T[K1][K2];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2]
  >(obj: T, key1: K1, key2: K2, key3: K3): T[K1][K2][K3];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2],
  K4 extends keyof T[K1][K2][K3]
  >(obj: T, key1: K1, key2: K2, key3: K3, key4: K4): T[K1][K2][K3][K4];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2],
  K4 extends keyof T[K1][K2][K3],
  K5 extends keyof T[K1][K2][K3][K4]
  >(obj: T, key1: K1, key2: K2, key3: K3, key4: K4, key5: K5): T[K1][K2][K3][K4][K5];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2],
  K4 extends keyof T[K1][K2][K3],
  K5 extends keyof T[K1][K2][K3][K4]
  >(obj: T, key1: K1, key2?: K2, key3?: K3, key4?: K4, key5?: K5):
  T[K1] |
  T[K1][K2] |
  T[K1][K2][K3] |
  T[K1][K2][K3][K4] |
  T[K1][K2][K3][K4][K5] {
    let value: any = obj && obj[key1];

    if (key2) {
      value = value && value[key2];
    }

    if (key3) {
      value = value && value[key3];
    }

    if (key4) {
      value = value && value[key4];
    }

    if (key5) {
      value = value && value[key5];
    }

    return value;
}

Example on playground.

You can do something like this:

    public myform()
    {
         InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
        this.myTableAdapter.Fill(this.myDataSet.someTable);
        comboBox1.SelectedItem = null;
        comboBox1.SelectedText = "--select--";           
    }

Essentially you are including the font into your project.

@font-face {
font-family: 'Open Sans';
font-style: normal;
font-weight: normal;

A bit too late but I got the same issue and fixed it switching schemalocation into schemaLocation in the persistence.xml file (line 1).

This solution will play the video upon clicking. You'll need to edit your picture to add a button image yourself.

You're going to need the URL of your picture and the YouTube video ID. The YouTube video id is the part of the URL after the v= parameter, so for https://www.youtube.com/watch?v=DODLEX4zzLQ the ID would be DODLEX4zzLQ.

<div width="560px" height="315px" style="position: static; clear: both; width: 560px; height: 315px;">&nbsp;<div style="position: relative"><img id="vidimg" width="560px" height="315px" src="URL_TO_PICTURE" style="position: absolute; top: 0; left: 0; cursor: pointer; pointer-events: none; z-index: 2;" /><iframe id="unlocked-video" style="position: absolute; top: 0; left: 0; z-index: 1;" src="https://www.youtube.com/embed/YOUTUBE_VIDEO_ID" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div></div>
<script type="application/javascript">
  // Adapted from https://stackoverflow.com/a/32138108
  var monitor = setInterval(function(){
    var elem = document.activeElement;
    if(elem && elem.id == 'unlocked-video'){
      document.getElementById('vidimg').style.display='none';
      clearInterval(monitor);
    }
  }, 100);
</script>

Be sure to replace URL_TO_PICTURE and YOUTUBE_VIDEO_ID in the above snippet.

To clarify what's going on here, this displays the image on top of the video, but allows clicks to pass through the image. The script monitors for clicks in the video iframe, and then hides the image if a click occurs. You may not need the float: clear.

I haven't compared this to the other answers here, but this is what I have used.

If you need by several params:

$ids = [1,2,3,4];
$not_ids = [5,6,7,8];
DB::table('table')->whereIn('id', $ids)
                  ->whereNotIn('id', $not_ids)
                  ->where('status', 1)
                  ->get();

Here is another take on the same thing which worked better for the situation I was in. It solves the problem where you have more than one remote, would like to clone all branches in remote source to remote destination but without having to check them all out beforehand.

(The problem I had with Daniel's solution was that it would refuse to checkout a tracking branch from the source remote if I had previously checked it out already, ie, it would not update my local branch before the push)

git push destination +refs/remotes/source/*:refs/heads/*

Note: If you are not using direct CLI, you must escape the asterisks:

git push destination +refs/remotes/source/\*:refs/heads/\*

• @mattalxndr

this will push all branches in remote source to a head branch in destination, possibly doing a non-fast-forward push. You still have to push tags separately.

I experienced this problem too. I discovered the problem is because Oracle DB does not like the space in C:program files (x86)\Toad...... so I created a new directory named C:App\Toad then reinstalled in it to connect Toad to Oracle. It worked.

First, make a display: block of your table

then, set overflow-x: to auto.

table {
    display: block;
    overflow-x: auto;
    white-space: nowrap;
}

Nice and clean. No superfluous formatting.

Here are more involved examples with scrolling table captions from a page on my website.

If an issue is taken about cells not filling the entire table, append the following additional CSS code:

table tbody {
    display: table;
    width: 100%;
}

nginx, like all well-behaved programs, can be configured not to self-daemonize.

Use the daemon off configuration directive described in http://wiki.nginx.org/CoreModule.

With JavaScript/Node.js: take a look at the vkBeautify.js plugin, which provides pretty printing for both JSON and XML text.

It's written in plain JavaScript, less than 1.5 KB (minified) and very fast.

You can do it easier with Gson:

Log.i(TAG, "SomeText: " + new Gson().toJson(yourMap));

The result will look like:

I/YOURTAG: SomeText: {"key1":"value1","key2":"value2"}

In Python 3, map returns an iterable object of type map, and not a subscriptible list, which would allow you to write map[i]. To force a list result, write

payIntList = list(map(int,payList))

However, in many cases, you can write out your code way nicer by not using indices. For example, with list comprehensions:

payIntList = [pi + 1000 for pi in payList]
for pi in payIntList:
    print(pi)

In VS2008, the doc entry that seems the most useful is:

Windows Presentation Foundation Building a WPF Application (WPF)

ms-help://MS.VSCC.v90/MS.MSDNQTR.v90.en/wpf_conceptual/html/a58696fd-bdad-4b55-9759-136dfdf8b91c.htm

ApplicationDefinition Identifies the XAML markup file that contains the application definition (a XAML markup file whose root element is Application). ApplicationDefinition is mandatory when Install is true and OutputType is winexe. A WPF application and, consequently, an MSBuild project can only have one ApplicationDefinition.

Page Identifies a XAML markup file whose content is converted to a binary format and compiled into an assembly. Page items are typically implemented in conjunction with a code-behind class.

The most common Page items are XAML files whose top-level elements are one of the following:

Window (System.Windows..::.Window).

Page (System.Windows.Controls..::.Page).

PageFunction (System.Windows.Navigation..::.PageFunction<(Of <(T>)>)).

ResourceDictionary (System.Windows..::.ResourceDictionary).

FlowDocument (System.Windows.Documents..::.FlowDocument).

UserControl (System.Windows.Controls..::.UserControl).

Resource Identifies a resource file that is compiled into an application assembly. As mentioned earlier, UICulture processes Resource items.

Content Identifies a content file that is distributed with an application. Metadata that describes the content file is compiled into the application (using AssemblyAssociatedContentFileAttribute).

var today = new Date().toISOString().split('T')[0];
$("#datePicker").val(today);

Above code will work.

As the message error says, you need to Increase the length of your column to fit the length of the data you are trying to insert (0000-00-00)

EDIT 1:

Following your comment, I run a test table:

mysql> create table testDate(id int(2) not null auto_increment, pdd date default null, primary key(id));
Query OK, 0 rows affected (0.20 sec)

Insertion:

mysql> insert into testDate values(1,'0000-00-00');
Query OK, 1 row affected (0.06 sec)

EDIT 2:

So, aparently you want to insert a NULL value to pdd field as your comment states ? You can do that in 2 ways like this:

Method 1:

mysql> insert into testDate values(2,'');
Query OK, 1 row affected, 1 warning (0.06 sec)

Method 2:

mysql> insert into testDate values(3,NULL);
Query OK, 1 row affected (0.07 sec)

EDIT 3:

You failed to change the default value of pdd field. Here is the syntax how to do it (in my case, I set it to NULL in the start, now I will change it to NOT NULL)

mysql> alter table testDate modify pdd date not null;
Query OK, 3 rows affected, 1 warning (0.60 sec)
Records: 3  Duplicates: 0  Warnings: 1

Try this code, I used the following code for cloning and removing the cloned element, i have also used new class (newClass) which can be added automatically with the newly cloned html

for cloning..

 $(".tr_clone_add").live('click', function() {
    var $tr    = $(this).closest('.tr_clone');
    var newClass='newClass';
    var $clone = $tr.clone().addClass(newClass);
    $clone.find(':text').val('');
    $tr.after($clone);
});

for removing the clone element.

$(".tr_clone_remove").live('click', function() { //Once remove button is clicked
    $(".newClass:last").remove(); //Remove field html
    x--; //Decrement field counter
});

html is as followinng

<tr class="tr_clone">
                       <!-- <td>1</td>-->
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span10" readonly>
                        <span><a href="javascript:void(0);" class="tr_clone_add" title="Add field"><span><i class="icon-plus-sign"></i></span></a> <a href="javascript:void(0);" class="tr_clone_remove" title="Remove field"><span style="color: #D63939;"><i class="icon-remove-sign"></i></span></a> </span> </td> </tr>

Don't think anyone has mentioned it yet, but if you are sure the data won't change underneath you, you may want to also apply the NoLock hint to ensure it is not blocked when reading.

SELECT CASE WHEN EXISTS (SELECT 1 
                     FROM dbo.[YourTable] WITH (NOLOCK)
                     WHERE [YourColumn] = [YourValue]) 
        THEN CAST (1 AS BIT) 
        ELSE CAST (0 AS BIT) END

feof() is not very intuitive. In my very humble opinion, the FILE's end-of-file state should be set to true if any read operation results in the end of file being reached. Instead, you have to manually check if the end of file has been reached after each read operation. For example, something like this will work if reading from a text file using fgetc():

#include <stdio.h>

int main(int argc, char *argv[])
{
  FILE *in = fopen("testfile.txt", "r");

  while(1) {
    char c = fgetc(in);
    if (feof(in)) break;
    printf("%c", c);
  }

  fclose(in);
  return 0;
}

It would be great if something like this would work instead:

#include <stdio.h>

int main(int argc, char *argv[])
{
  FILE *in = fopen("testfile.txt", "r");

  while(!feof(in)) {
    printf("%c", fgetc(in));
  }

  fclose(in);
  return 0;
}

For targeting IE only in my stylesheets, I use this Sass Mixin :

@mixin ie-only {
  @media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
    @content;
  }
}

If I can rephrase your question, what you want is a dictionary with the years as keys and an array for each year containing a list of values associated with that year, right? Here's how I'd do it:

years_dict = dict()

for line in list:
    if line[0] in years_dict:
        # append the new number to the existing array at this slot
        years_dict[line[0]].append(line[1])
    else:
        # create a new array in this slot
        years_dict[line[0]] = [line[1]]

What you should end up with in years_dict is a dictionary that looks like the following:

{
    "2010": [2],
    "2009": [4,7],
    "1989": [8]
}

In general, it's poor programming practice to create "parallel arrays", where items are implicitly associated with each other by having the same index rather than being proper children of a container that encompasses them both.

Reverse the items in a sub-list

int[] l = {0, 1, 2, 3, 4, 5, 6};
var res = new List<int>();
res.AddRange(l.Where((n, i) => i < 2));
res.AddRange(l.Where((n, i) => i >= 2 && i <= 4).Reverse());
res.AddRange(l.Where((n, i) => i > 4));

Gives 0,1,4,3,2,5,6

It seems there's some misunderstanding. So, instead of trying to patch VS2013 here's and answer from a Microsoft guy: https://social.msdn.microsoft.com/Forums/vstudio/en-US/49ba9a67-d26a-4b21-80ef-caeb081b878e/will-c-60-ever-be-supported-by-vs-2013?forum=roslyn

It's necessary because, more or less, when we import a project from git, it's not a maven project, so the maven dependencies are not in the build path.

Here's what I have done to turn a general project to a maven project.

general project-->java project right click the project, properties->project facets, click "java". This step will turn a general project into java project.

java project --> maven project right click project, configure-->convert to maven project At this moment, maven dependencies lib are still not in the build path. project properties, build path, add library, add maven dependencies lib

And wait a few seconds, when the dependencies are loaded, the project is ready!

From the documentation:

We can add to a list in many ways:

assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
    //equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]

def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]

list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]

list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']

You can also do:

def myNewList = myList << "fifth"

find / -name php.ini

Hey... it worked for me!

The difference between those will depend largely on what browser you are currently referring to. Each one implements these properties differently, or not at all. Quirksmode has great documentation regarding browser differences in regards to W3C standards like the DOM and JavaScript Events.

Here's another way -

cat > outfile.txt
>Enter text

You can use:

import operator
import functools
functools.reduce(operator.mul, [1,2,3,4,5,6], 1)

See reduce and operator.mul documentations for an explanation.

You need the import functools line in Python 3+.

You forgot to add std:: namespace prefix to vector class name.

I suggest to have array of buffers and concat to resulting buffer only once at the end. Its easy to do manually, or one could use node-buffers

As explained in Python's super() considered super, one way is to have class eat the arguments it requires, and pass the rest on. Thus, when the call-chain reaches object, all arguments have been eaten, and object.__init__ will be called without arguments (as it expects). So your code should look like this:

class A(object):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(object):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(*args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(*args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(*args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10, 20, 30)

I've come up with a single line of code to set at top of my every php script as to compensate:

<?php if(!$root) for($i=count(explode("/",$_SERVER["PHP_SELF"]));$i>2;$i--) $root .= "../"; ?>

By this building $root to bee "../" steps up in hierarchy from wherever the file is placed. Whenever I want to include with an absolut path the line will be:

<?php include($root."some/include/directory/file.php"); ?>

I don't really like it, seems as an awkward way to solve it, but it seem to work whatever system php runs on and wherever the file is placed, making it system independent. To reach files outside the web directory add some more ../ after $root, e.g. $root."../external/file.txt".

Linting is a process by a linter program that analyzes source code in a particular programming language and flag potential problems like syntax errors, deviations from a prescribed coding style or using constructs known to be unsafe.

For example, a JavaScript linter would flag the first use of parseInt below as unsafe:

// without a radix argument - Unsafe
var count = parseInt(countString);

// with a radix paremeter specified - Safe
var count = parseInt(countString, 10);

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

If you are using opencv3, you can print Mat like python numpy style:

Mat xTrainData = (Mat_<float>(5,2) << 1, 1, 1, 1, 2, 2, 2, 2, 2, 2);

cout << "xTrainData (python)  = " << endl << format(xTrainData, Formatter::FMT_PYTHON) << endl << endl;

Output as below, you can see it'e more readable, see here for more information.

But in most case, there is no need to output all the data in Mat, you can output by row range like 0 ~ 2 row:

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

#include <iostream>
#include <iomanip>

using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
    //row: 6, column: 3,unsigned one channel
    Mat image1(6, 3, CV_8UC1, 5);

    // output row: 0 ~ 2
    cout << "image1 row: 0~2 = "<< endl << " "  << image1.rowRange(0, 2) << endl << endl;

    //row: 8, column: 2,unsigned three channel
    Mat image2(8, 2, CV_8UC3, Scalar(1, 2, 3));

    // output row: 0 ~ 2
    cout << "image2 row: 0~2 = "<< endl << " "  << image2.rowRange(0, 2) << endl << endl;

    return 0;
}

Output as below:

To expand on Paul's own answer, he has demonstrated that the bytecode is the same on that particular compiler (presumably Sun's javac?) but different compilers are not guaranteed to generate the same bytecode, right? To see what the actual difference is between the two, let's go straight to the source and check the Java Language Specification, specifically 14.14.2, "The enhanced for statement":

The enhanced for statement is equivalent to a basic for statement of the form:

for (I #i = Expression.iterator(); #i.hasNext(); ) {
    VariableModifiers(opt) Type Identifier = #i.next();    
    Statement 
}

In other words, it is required by the JLS that the two are equivalent. In theory that could mean marginal differences in bytecode, but in reality the enhanced for loop is required to:

• Invoke the .iterator() method
• Use .hasNext()
• Make the local variable available via .next()

So, in other words, for all practical purposes the bytecode will be identical, or nearly-identical. It's hard to envisage any compiler implementation which would result in any significant difference between the two.

Try to add this:

curl_setopt($ch, CURLOPT_HEADER, 1); 
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); 

Document has already explain the usage. So I am using SQL to explain these methods

Example:

Assuming there is an Order (orders) has many OrderItem (order_items).

And you have already build the relationship between them.

// App\Models\Order:
public function orderItems() {
    return $this->hasMany('App\Models\OrderItem', 'order_id', 'id');
}

These three methods are all based on a relationship.

With

Result: with() return the model object and its related results.

Advantage: It is eager-loading which can prevent the N+1 problem.

When you are using the following Eloquent Builder:

Order::with('orderItems')->get();

Laravel change this code to only two SQL:

// get all orders:
SELECT * FROM orders; 

// get the order_items based on the orders' id above
SELECT * FROM order_items WHERE order_items.order_id IN (1,2,3,4...);

And then laravel merge the results of the second SQL as different from the results of the first SQL by foreign key. At last return the collection results.

So if you selected columns without the foreign_key in closure, the relationship result will be empty:

Order::with(['orderItems' => function($query) { 
           // $query->sum('quantity');
           $query->select('quantity'); // without `order_id`
       }
])->get();

#=> result:
[{  id: 1,
    code: '00001',
    orderItems: [],    // <== is empty
  },{
    id: 2,
    code: '00002',
    orderItems: [],    // <== is empty
  }...
}]

Has

Has will return the model's object that its relationship is not empty.

Order::has('orderItems')->get();

Laravel change this code to one SQL:

select * from `orders` where exists (
    select * from `order_items` where `order`.`id` = `order_item`.`order_id`
)

whereHas

whereHas and orWhereHas methods to put where conditions on your has queries. These methods allow you to add customized constraints to a relationship constraint.

Order::whereHas('orderItems', function($query) {
   $query->where('status', 1);
})->get();

Laravel change this code to one SQL:

select * from `orders` where exists (
    select * 
    from `order_items` 
    where `orders`.`id` = `order_items`.`order_id` and `status` = 1
)

For Azure I used this:

You should have SSMS v17.x+

I used;

With this, as User Sparrow has mentioned:

Open your Databases> and select Tables,
Then press key F7 You should see the row count
as:

SSMS here is connected to Azure databases

Try this:

$array_one = ['ratio_type'];
$array_two = ['ratio_type', 'ratio_type'];
$array_three = ['ratio_type'];
$array_four = ['ratio_type'];
$array_five = ['ratio_type', 'ratio_type', 'ratio_type'];
$array_six = ['ratio_type'];
$array_seven = ['ratio_type'];
$array_eight = ['ratio_type'];

$all_array_elements = array_merge_recursive(
    $array_one,
    $array_two,
    $array_three,
    $array_four,
    $array_five,
    $array_six,
    $array_seven,
    $array_eight
);

foreach ($all_array_elements as $key => $value) {
    echo "[$key]" . ' - ' . $value . PHP_EOL;
}

// OR
var_dump($all_array_elements);

I like your question, regardless of whether it's off topic or not :P

An interesting aside; I've just completed a subject in my degree where we covered robotics and computer vision. Our project for the semester was incredibly similar to the one you describe.

We had to develop a robot that used an Xbox Kinect to detect coke bottles and cans on any orientation in a variety of lighting and environmental conditions. Our solution involved using a band pass filter on the Hue channel in combination with the hough circle transform. We were able to constrain the environment a bit (we could chose where and how to position the robot and Kinect sensor), otherwise we were going to use the SIFT or SURF transforms.

You can read about our approach on my blog post on the topic :)

A very simple example is that if you have a UserService that has @Autowired jpa resposiroty UserRepository

...
class UserService{

  @Autowired
  UserRepository userRepository;
...
}

then in the test class for UserService you will do

...
class TestUserService{
  @Mock 
  UserRepository userRepository;

  @InjectMocks
  UserService userService;

...
}

@InjectMocks tells the framework that take the @Mock UserRepository userRespository; and inject that into userService so rather than auto wiring a real instance of UserRepository a Mock of UserRepository will be injected in userService.

It's a shame that we need multiple ARG too, it results in multiple layers and slows down the build because of that, and for anyone also wondering that, currently there is no way to set multiple ARGs.

It occurred to me that you may have actually be asking how to implement the + operator for dictionaries, the following seems to work:

>>> class Dict(dict):
...     def __add__(self, other):
...         copy = self.copy()
...         copy.update(other)
...         return copy
...     def __radd__(self, other):
...         copy = other.copy()
...         copy.update(self)
...         return copy
... 
>>> default_data = Dict({'item1': 1, 'item2': 2})
>>> default_data + {'item3': 3}
{'item2': 2, 'item3': 3, 'item1': 1}
>>> {'test1': 1} + Dict(test2=2)
{'test1': 1, 'test2': 2}

Note that this is more overhead then using dict[key] = value or dict.update(), so I would recommend against using this solution unless you intend to create a new dictionary anyway.

It seems like you have it worked out, but for others looking for this answer, an easy way to do this is by printing to stderr. You can do that like this:

from __future__ import print_function # In python 2.7
import sys

@app.route('/button/')
def button_clicked():
    print('Hello world!', file=sys.stderr)
    return redirect('/')

Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post

No need to go in such deep technicalities, and get yourself blasted. Let me explain it in the most easiest way. We all have studied "Sets" during our school-age in Mathematics. Just consider 3D numpy array as the formation of "sets".

x = np.zeros((2,3,4)) 

Simply Means:

2 Sets, 3 Rows per Set, 4 Columns

Example:

Input

x = np.zeros((2,3,4))

Output

Set # 1 ---- [[[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]], ---- Row 3 
    
Set # 2 ----  [[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]]] ---- Row 3

Explanation: See? we have 2 Sets, 3 Rows per Set, and 4 Columns.

Note: Whenever you see a "Set of numbers" closed in double brackets from both ends. Consider it as a "set". And 3D and 3D+ arrays are always built on these "sets".

Try this.

In this example, I'm targeting it with its input name and value

$("input[name=background][value='some value']").prop("checked",true);

Good to know: in case of multi-word value, it will work because of apostrophes, too.

set PYTHONIOENCODING=utf-8
set PYTHONLEGACYWINDOWSSTDIO=utf-8

You may or may not need to set that second environment variable PYTHONLEGACYWINDOWSSTDIO.

Alternatively, this can be done in code (although it seems that doing it through env vars is recommended):

sys.stdin.reconfigure(encoding='utf-8')
sys.stdout.reconfigure(encoding='utf-8')

Additionally: Reproducing this error was a bit of a pain, so leaving this here too in case you need to reproduce it on your machine:

set PYTHONIOENCODING=windows-1252
set PYTHONLEGACYWINDOWSSTDIO=windows-1252

Runtime#totalMemory - the memory that the JVM has allocated thus far. This isn't necessarily what is in use or the maximum.

Runtime#maxMemory - the maximum amount of memory that the JVM has been configured to use. Once your process reaches this amount, the JVM will not allocate more and instead GC much more frequently.

Runtime#freeMemory - I'm not sure if this is measured from the max or the portion of the total that is unused. I am guessing it is a measurement of the portion of total which is unused.

Tim is correct, and Shane has an omission. Here are additional examples:

R> df <- data.frame(a = as.character(10:15))
R> df <- data.frame(df, num = as.numeric(df$a), 
                        numchr = as.numeric(as.character(df$a)))
R> df
   a num numchr
1 10   1     10
2 11   2     11
3 12   3     12
4 13   4     13
5 14   5     14
6 15   6     15
R> summary(df)
  a          num           numchr    
 10:1   Min.   :1.00   Min.   :10.0  
 11:1   1st Qu.:2.25   1st Qu.:11.2  
 12:1   Median :3.50   Median :12.5  
 13:1   Mean   :3.50   Mean   :12.5  
 14:1   3rd Qu.:4.75   3rd Qu.:13.8  
 15:1   Max.   :6.00   Max.   :15.0  
R> 

Our data.frame now has a summary of the factor column (counts) and numeric summaries of the as.numeric() --- which is wrong as it got the numeric factor levels --- and the (correct) summary of the as.numeric(as.character()).

To print the columns with a specific string, you use the // search pattern. For example, if you are looking for second columns that contains abc:

awk '$2 ~ /abc/'

... and if you want to print only a particular column:

awk '$2 ~ /abc/ { print $3 }'

... and for a particular line number:

awk '$2 ~ /abc/ && FNR == 5 { print $3 }'

For me it works with:

npm run ng <command>

The Rob Evans anwser works correctly for me but when I use request.abort(), it occurs to throw a socket hang up error which stays unhandled.

I had to add an error handler for the request object :

var options = { ... }
var req = http.request(options, function(res) {
  // Usual stuff: on(data), on(end), chunks, etc...
}

req.on('socket', function (socket) {
    socket.setTimeout(myTimeout);  
    socket.on('timeout', function() {
        req.abort();
    });
}

req.on('error', function(err) {
    if (err.code === "ECONNRESET") {
        console.log("Timeout occurs");
        //specific error treatment
    }
    //other error treatment
});

req.write('something');
req.end();

I had the same problem because my "Dynamic Web Project" had no reference to the installed server i wanted to use and therefore had no reference to the Servlet API the server provides.

Following steps solved it without adding an extra Servlet-API to the Java Build Path (Eclipse version: Luna):

• Right click on your "Dynamic Web Project"
• Select Properties
• Select Project Facets in the list on the left side of the "Properties" wizard
• On the right side of the wizard you should see a tab named Runtimes. Select the Runtime tab and check the server you want to run the servlet.

Edit: if there is no server listed you can create a new one on the Runtimes tab

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

The subset command is not necessary. Just use data frame indexing

studentdata[studentdata$Drink == 'water',]

Read the warning from ?subset

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.

Use Css Selector for this, or learn more about Css Selector just go here https://www.w3schools.com/cssref/css_selectors.asp

#main_text > .title {
  /* Style goes here */
}

#main_text .title {
  /* Style goes here */
}

For this you can use the readonly modifier. Object properties which are readonly can only be assigned during initialization of the object.

Example in classes:

class Circle {
  readonly radius: number;

  constructor(radius: number) {
    this.radius = radius;
  }

  get area() {
    return Math.PI * this.radius * 2;
  }
}

const circle = new Circle(12);
circle.radius = 12; // Cannot assign to 'radius' because it is a read-only property.

Example in Object literals:

type Rectangle = {
  readonly height: number;
  readonly width: number;
};

const square: Rectangle = { height: 1, width: 2 };
square.height = 5 // Cannot assign to 'height' because it is a read-only property

It's also worth knowing that the readonly modifier is purely a typescript construct and when the TS is compiled to JS the construct will not be present in the compiled JS. When we are modifying properties which are readonly the TS compiler will warn us about it (it is valid JS).

<a href="javascript:;" onclick="window.location = 'http://example.com/submit.php?url=' + escape(document.location.href);'">Go</a>;

I have tried xlrd, pandas, openpyxl and other such libraries and all of them seem to take exponential time as the file size increase as it reads the entire file. The other solutions mentioned above where they used 'on_demand' did not work for me. If you just want to get the sheet names initially, the following function works for xlsx files.

def get_sheet_details(file_path):
    sheets = []
    file_name = os.path.splitext(os.path.split(file_path)[-1])[0]
    # Make a temporary directory with the file name
    directory_to_extract_to = os.path.join(settings.MEDIA_ROOT, file_name)
    os.mkdir(directory_to_extract_to)

    # Extract the xlsx file as it is just a zip file
    zip_ref = zipfile.ZipFile(file_path, 'r')
    zip_ref.extractall(directory_to_extract_to)
    zip_ref.close()

    # Open the workbook.xml which is very light and only has meta data, get sheets from it
    path_to_workbook = os.path.join(directory_to_extract_to, 'xl', 'workbook.xml')
    with open(path_to_workbook, 'r') as f:
        xml = f.read()
        dictionary = xmltodict.parse(xml)
        for sheet in dictionary['workbook']['sheets']['sheet']:
            sheet_details = {
                'id': sheet['@sheetId'],
                'name': sheet['@name']
            }
            sheets.append(sheet_details)

    # Delete the extracted files directory
    shutil.rmtree(directory_to_extract_to)
    return sheets

Since all xlsx are basically zipped files, we extract the underlying xml data and read sheet names from the workbook directly which takes a fraction of a second as compared to the library functions.

Benchmarking: (On a 6mb xlsx file with 4 sheets)
Pandas, xlrd: 12 seconds
openpyxl: 24 seconds
Proposed method: 0.4 seconds

Since my requirement was just reading the sheet names, the unnecessary overhead of reading the entire time was bugging me so I took this route instead.

Mikeal's request module can do this easily:

var request = require('request');

var options = {
  uri: 'https://www.googleapis.com/urlshortener/v1/url',
  method: 'POST',
  json: {
    "longUrl": "http://www.google.com/"
  }
};

request(options, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body.id) // Print the shortened url.
  }
});

try

var lst= (from char c in source select c.ToString()).ToList();

I would like to add some more things on top of Bert F answer.

Locks support various methods for finer grained lock control, which are more expressive than implicit monitors (synchronized locks)

A Lock provides exclusive access to a shared resource: only one thread at a time can acquire the lock and all access to the shared resource requires that the lock be acquired first. However, some locks may allow concurrent access to a shared resource, such as the read lock of a ReadWriteLock.

Advantages of Lock over Synchronization from documentation page

1. The use of synchronized methods or statements provides access to the implicit monitor lock associated with every object, but forces all lock acquisition and release to occur in a block-structured way

2. Lock implementations provide additional functionality over the use of synchronized methods and statements by providing a non-blocking attempt to acquire a lock (tryLock()), an attempt to acquire the lock that can be interrupted (lockInterruptibly(), and an attempt to acquire the lock that can timeout (tryLock(long, TimeUnit)).

3. A Lock class can also provide behavior and semantics that is quite different from that of the implicit monitor lock, such as guaranteed ordering, non-reentrant usage, or deadlock detection

ReentrantLock: In simple terms as per my understanding, ReentrantLock allows an object to re-enter from one critical section to other critical section . Since you already have lock to enter one critical section, you can other critical section on same object by using current lock.

ReentrantLock key features as per this article

1. Ability to lock interruptibly.
2. Ability to timeout while waiting for lock.
3. Power to create fair lock.
4. API to get list of waiting thread for lock.
5. Flexibility to try for lock without blocking.

You can use ReentrantReadWriteLock.ReadLock, ReentrantReadWriteLock.WriteLock to further acquire control on granular locking on read and write operations.

Apart from these three ReentrantLocks, java 8 provides one more Lock

StampedLock:

Java 8 ships with a new kind of lock called StampedLock which also support read and write locks just like in the example above. In contrast to ReadWriteLock the locking methods of a StampedLock return a stamp represented by a long value.

You can use these stamps to either release a lock or to check if the lock is still valid. Additionally stamped locks support another lock mode called optimistic locking.

Have a look at this article on usage of different type of ReentrantLock and StampedLock locks.

I would have rather commented but I don't have a high enough rep.

As far as I am aware, for positive arguments and a divisor which is a power of 2, this is the fastest way (tested in CUDA):

//example y=8
q = (x >> 3) + !!(x & 7);

For generic positive arguments only, I tend to do it like so:

q = x/y + !!(x % y);

If you want to do an ajax call or a simple javascript function, don't forget to close your function with the return false

like this:

function DoAction(id, name) 
{ 
    // your code
    return false;
}

Use this function from stringi package

stri_trans_totitle(c("zip code", "state", "final count"))
## [1] "Zip Code"      "State"       "Final Count" 

stri_trans_totitle("i like pizza very much")
## [1] "I Like Pizza Very Much"

You might consider running Fiddler as a reverse proxy, you should be able to get clients to connect to Fiddler's address and then forward the requests from Fiddler to your application.

This will require either a bit of port manipulation or client config, depending on what's easier based on your requirements.

Details of how to do it are here: http://www.fiddler2.com/Fiddler/Help/ReverseProxy.asp

Put the jquery js link before the bootstrap js link like so:

<script type="text/javascript" src="Scripts/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="Scripts/bootstrap.min.js"></script>

instead of:

<script type="text/javascript" src="Scripts/bootstrap.min.js"></script>
<script type="text/javascript" src="Scripts/jquery-2.1.1.min.js"></script>

FWIW, htpasswd -n username will output the result directly to stdout, and avoid touching files altogether.

If you want to sum all values of one column, it's more efficient to use DataFrame's internal RDD and reduce.

import sqlContext.implicits._
import org.apache.spark.sql.functions._

val df = sc.parallelize(Array(10,2,3,4)).toDF("steps")
df.select(col("steps")).rdd.map(_(0).asInstanceOf[Int]).reduce(_+_)

//res1 Int = 19

POM(Project Object Model) is nothing but the automation script for building the project,we can write the automation script in XML, the building script files are named diffrenetly in different Automation tools

like we call build.xml in ANT,pom.xml in MAVEN

MAVEN can packages jars,wars, ears and POM which new thing to all of us

if you want check WHAT IS POM.XML

Linked-list are especially useful when the collection is constantly growing & shrinking. For example, it's hard to imagine trying to implement a Queue (add to the end, remove from the front) using an array -- you'd be spending all your time shifting things down. On the other hand, it's trivial with a linked-list.

You can also use

./gradlew clean build (Mac and Linux) -With ./

gradlew clean build (Windows) -Without ./

it removes build folder, as well configure your modules and then build your project.

i use it before release any new app on playstore.

var context = new DatabaseEntities();

var t = new test //Make sure you have a table called test in DB
{
    ID = Guid.NewGuid(),
    name = "blah",
};

context.test.Add(t);
context.SaveChanges();

Should do it

You're close, you just need to delete the file before trying to over-write it.

dim infolder: set infolder = fso.GetFolder(IN_PATH)
dim file: for each file in infolder.Files

    dim name: name = file.name
    dim parts: parts = split(name, ".")

    if UBound(parts) = 2 then

       ' file name like a.c.pdf    

        dim newname: newname = parts(0) & "." & parts(2)
        dim newpath: newpath = fso.BuildPath(OUT_PATH, newname)

        ' warning:
        ' if we have source files C:\IN_PATH\ABC.01.PDF, C:\IN_PATH\ABC.02.PDF, ...
        ' only one of them will be saved as D:\OUT_PATH\ABC.PDF

        if fso.FileExists(newpath) then
            fso.DeleteFile newpath
        end if

        file.Move newpath

    end if

next

try this

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.example.android"));
startActivity(intent);

You could do this:

var timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("someSelector"), userInfo: nil, repeats: false)

func someSelector() {
    // Something after a delay
}

SWIFT 3

let timer = Timer.scheduledTimer(timeInterval: 0.1, target: self, selector: #selector(someSelector), userInfo: nil, repeats: false)

func someSelector() {
    // Something after a delay
}

You can use the jquery.soap plugin to do the work for you.

This script uses $.ajax to send a SOAPEnvelope. It can take XML DOM, XML string or JSON as input and the response can be returned as either XML DOM, XML string or JSON too.

Example usage from the site:

$.soap({
    url: 'http://my.server.com/soapservices/',
    method: 'helloWorld',

    data: {
        name: 'Remy Blom',
        msg: 'Hi!'
    },

    success: function (soapResponse) {
        // do stuff with soapResponse
        // if you want to have the response as JSON use soapResponse.toJSON();
        // or soapResponse.toString() to get XML string
        // or soapResponse.toXML() to get XML DOM
    },
    error: function (SOAPResponse) {

You can compare class tokens to each other, so you could use value.getClass() == Integer.class. However, the simpler and more canonical way is to use instanceof :

    if (value instanceof Integer) {
        System.out.println("This is an Integer");
    } else if(value instanceof String) {
        System.out.println("This is a String");
    } else if(value instanceof Float) {
        System.out.println("This is a Float");
    }

Notes:

• the only difference between the two is that comparing class tokens detects exact matches only, while instanceof C matches for subclasses of C too. However, in this case all the classes listed are final, so they have no subclasses. Thus instanceof is probably fine here.

• as JB Nizet stated, such checks are not OO design. You may be able to solve this problem in a more OO way, e.g.

  System.out.println("This is a(n) " + value.getClass().getSimpleName());
  

I think you will find that if your web app is performing a complex operation then provided feedback is given to the user, they won't mind (too much).

For example: Loading Google Mail.

android developers documentation says : "Updated the AppCompatActivity as the base class for activities that use the support library action bar features. This class replaces the deprecated ActionBarActivity."

checkout changes for Android Support Library, revision 22.1.0 (April 2015)

Another Java 8+ way would be to create a forEach method that does not crash when using a null value:

public static <T> void forEach(Iterable<T> set, Consumer<T> action) {
    if (set != null) {
        set.forEach(action);
    }
}

The usage of the own defined foreach is close to the native Java 8 one:

ArrayList<T> list = null;

//java 8+ (will throw a NullPointerException)
list.forEach(item -> doSomething(...) );

//own implementation
forEach(list, item -> doSomething(...) );

Use @Kristian Antonsen's answer, or you can use:

$('button').click(function() {
    preventDefault();
    captureForm();
});

Don't forget to set table name da.Fill(ds,"tablename");

So you return data using table name instead of 0

if (ds.Tables["tablename"].Rows.Count == 0)
 {
  MessageBox.Show("No result found");
 }

In the old days, "/opt" was used by UNIX vendors like AT&T, Sun, DEC and 3rd-party vendors to hold "Option" packages; i.e. packages that you might have paid extra money for. I don't recall seeing "/opt" on Berkeley BSD UNIX. They used "/usr/local" for stuff that you installed yourself.

But of course, the true "meaning" of the different directories has always been somewhat vague. That is arguably a good thing, because if these directories had precise (and rigidly enforced) meanings you'd end up with a proliferation of different directory names.

According to the Filesystem Hierarchy Standard, /opt is for "the installation of add-on application software packages". /usr/local is "for use by the system administrator when installing software locally".

Before launching webdriver, we just set this environment variable to let chrome generate it:

export CHROME_LOG_FILE=$(pwd)/tests/e2e2/logs/client.log

I prefer TextMate on OS X. But Netbeans (multi-platform) is coming along quite nicely. Plus it comes with its IDE fully functional debugger.

open up your console and hit the URL inside. it'll take you to the API page and then in the page accept the SSL certificate, go back to your app page and reload. remember that SSL certificates should have been issued for your Dev environment before.

If you are using two DateTime objects, one to store the date the other the time, you could do the following:

var date = new DateTime(2016,6,28);

var time = new DateTime(1,1,1,13,13,13);

var combinedDateTime = date.AddTicks(time.TimeOfDay.Ticks);

An example of this can be found here

I think you can go with JWT (Json Web Tokens).

First you need to install the package System.IdentityModel.Tokens.Jwt:

$ dotnet add package System.IdentityModel.Tokens.Jwt

You will need to add a controller for token generation and authentication like this one:

public class TokenController : Controller
{
    [Route("/token")]

    [HttpPost]
    public IActionResult Create(string username, string password)
    {
        if (IsValidUserAndPasswordCombination(username, password))
            return new ObjectResult(GenerateToken(username));
        return BadRequest();
    }

    private bool IsValidUserAndPasswordCombination(string username, string password)
    {
        return !string.IsNullOrEmpty(username) && username == password;
    }

    private string GenerateToken(string username)
    {
        var claims = new Claim[]
        {
            new Claim(ClaimTypes.Name, username),
            new Claim(JwtRegisteredClaimNames.Nbf, new DateTimeOffset(DateTime.Now).ToUnixTimeSeconds().ToString()),
            new Claim(JwtRegisteredClaimNames.Exp, new DateTimeOffset(DateTime.Now.AddDays(1)).ToUnixTimeSeconds().ToString()),
        };

        var token = new JwtSecurityToken(
            new JwtHeader(new SigningCredentials(
                new SymmetricSecurityKey(Encoding.UTF8.GetBytes("Secret Key You Devise")),
                                         SecurityAlgorithms.HmacSha256)),
            new JwtPayload(claims));

        return new JwtSecurityTokenHandler().WriteToken(token);
    }
}

After that update Startup.cs class to look like below:

namespace WebAPISecurity
{   
public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        services.AddAuthentication(options => {
            options.DefaultAuthenticateScheme = "JwtBearer";
            options.DefaultChallengeScheme = "JwtBearer";
        })
        .AddJwtBearer("JwtBearer", jwtBearerOptions =>
        {
            jwtBearerOptions.TokenValidationParameters = new TokenValidationParameters
            {
                ValidateIssuerSigningKey = true,
                IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("Secret Key You Devise")),
                ValidateIssuer = false,
                //ValidIssuer = "The name of the issuer",
                ValidateAudience = false,
                //ValidAudience = "The name of the audience",
                ValidateLifetime = true, //validate the expiration and not before values in the token
                ClockSkew = TimeSpan.FromMinutes(5) //5 minute tolerance for the expiration date
            };
        });

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseAuthentication();

        app.UseMvc();
    }
}

And that's it, what is left now is to put [Authorize] attribute on the Controllers or Actions you want.

Here is a link of a complete straight forward tutorial.

Aside from suggesting you read the docs for retrieve() carefully (http://docs.python.org/library/urllib.html#urllib.URLopener.retrieve), I would suggest actually calling read() on the content of the response, and then saving it into a file of your choosing rather than leaving it in the temporary file that retrieve creates.

Best would be not using LinkedList at all, usually it is slower in all disciplines, and less handy. (When mainly inserting/deleting to the front, especially for big arrays LinkedList is faster)

Use ArrayList, and iterate with

int len = list.size();
for (int i = 0; i < len; i++) {
  Element ele = list.get(i);
}

Reset is trivial, just loop again.
If you insist on using an iterator, then you have to use a new iterator:

iter = list.listIterator();

(I saw only once in my life an advantage of LinkedList: i could loop through whith a while loop and remove the first element)

Here are the three web pages on which we found the answer. The most difficult part was setting up static ports for SQLEXPRESS.

Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.

How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.

How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.

Delegate.BeginInvoke() asynchronously queues the call of a delegate and returns control immediately. When using Delegate.BeginInvoke(), you should call Delegate.EndInvoke() in the callback method to get the results.

Delegate.Invoke() synchronously calls the delegate in the same thread.

MSDN Article

You can use the following line to drop the first two columns (or any column you don't need):

df.drop([df.columns[0], df.columns[1]], axis=1)

Reference

int space = 40;
printf("%*s", space, "Hello");

This statement will reserve a row of 40 characters, print string at the end of the row (removing extra spaces such that the total row length is constant at 40). Same can be used for characters and integers as follows:

printf("%*d", space, 10);
printf("%*c", space, 'x');

This method using a parameter to determine spaces is useful where a variable number of spaces is required. These statements will still work with integer literals as follows:

printf("%*d", 10, 10);
printf("%*c", 20, 'x');
printf("%*s", 30, "Hello");

Hope this helps someone like me in future.

Fast solution:

SELECT * FROM TABLE1

WPF4

<DataGrid AutoGenerateColumns="True" Grid.Column="0" Grid.Row="0"
      ScrollViewer.CanContentScroll="True" 
      ScrollViewer.VerticalScrollBarVisibility="Auto"
      ScrollViewer.HorizontalScrollBarVisibility="Auto">
</DataGrid>

with : <ColumnDefinition Width="350" /> & <RowDefinition Height="300" /> works fine.

Scrollbars don't show with <ColumnDefinition Width="Auto" /> & <RowDefinition Height="300" />.

Also works fine with: <ColumnDefinition Width="*" /> & <RowDefinition Height="300" /> in the case where this is nested within an outer <Grid>.

I have tried to use the above suggestions and my program crashed, than I figured out the file I'm trying to identify was used and when trying to use 'os.path.getctime' it crashed. what finally worked for me was:

    files_before = glob.glob(os.path.join(my_path,'*'))
    **code where new file is created**
    new_file = set(files_before).symmetric_difference(set(glob.glob(os.path.join(my_path,'*'))))

this codes gets the uncommon object between the two sets of file lists its not the most elegant, and if multiple files are created at the same time it would probably won't be stable

To make this process more robust, you could consider using the SAX parser (that way you don't have to hold the whole file in memory), read & write till the end of tree and then start appending.

just posting in case anyone else has the same error...

I was using 'await' outside of an 'async' function and for whatever reason that results in a 'missing ) after argument list' error.

The solution was to make the function asynchronous

function functionName(args) {}

becomes

async function functionName(args) {}

You need not store the diff in a 3rd file and then read from in. Instead you make use of the Runtime.exec

Process p = Runtime.getRuntime().exec("diff fileA fileB");
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
while ((s = stdInput.readLine()) != null) {
        System.out.println(s);
}

Scripting is inevitable.

This isn't provided because of the security risk. <input type='file' /> is closest, but not what you are looking for.

Checkout this example that uses Javascript to achieve what you want.

If the OS is windows, you can use VB scripts to access the core control files to browse for a folder.

You're close.

std::list<Student>::iterator it;
for (it = data.begin(); it != data.end(); ++it){
    std::cout << it->name;
}

Note that you can define it inside the for loop:

for (std::list<Student>::iterator it = data.begin(); it != data.end(); ++it){
    std::cout << it->name;
}

And if you are using C++11 then you can use a range-based for loop instead:

for (auto const& i : data) {
    std::cout << i.name;
}

Here auto automatically deduces the correct type. You could have written Student const& i instead.

To get better results and robustness against differents types of matrices, you can do this in addition to the first answer, that copy the data :

cv::Mat source = getYourSource();

// Setup a rectangle to define your region of interest
cv::Rect myROI(10, 10, 100, 100);

// Crop the full image to that image contained by the rectangle myROI
// Note that this doesn't copy the data
cv::Mat croppedRef(source, myROI);

cv::Mat cropped;
// Copy the data into new matrix
croppedRef.copyTo(cropped);

Any crawler or spider will read your index.htm or equivalent, that is exposed to the web, they will read the source code for that page, and find everything that is associated to that webpage and contains subdirectories. If they find a "contact us" button, there may be is included the path to the webpage or php that deal with the contact-us action, so they now have one more subdirectory/folder name to crawl and dig more. But even so, if that folder has a index.htm or equivalent file, it will not list all the files in such folder.

If by mistake, the programmer never included an index.htm file in such folder, then all the files will be listed on your computer screen, and also for the crawler/spider to keep digging. But, if you created a folder www.yoursite.com/nombresinistro75crazyragazzo19/ and put several files in there, and never published any button or never exposed that folder address anywhere in the net, keeping only in your head, chances are that nobody ever will find that path, with crawler or spider, for more sophisticated it can be.

Except, of course, if they can enter your FTP or access your site control panel.

You can detect a lot of heap corruption problems by enabling Page Heap for your application . To do this you need to use gflags.exe that comes as a part of Debugging Tools For Windows

Run Gflags.exe and in the Image file options for your executable, check "Enable Page Heap" option.

Now restart your exe and attach to a debugger. With Page Heap enabled, the application will break into debugger whenever any heap corruption occurs.
