As Sotirios Delimanolis already pointed out in the comments, there are two options:

Return ResponseEntity with error message

Change your method like this:

@RequestMapping(method = RequestMethod.GET)
public ResponseEntity getUser(@RequestHeader(value="Access-key") String accessKey,
                              @RequestHeader(value="Secret-key") String secretKey) {
    try {
        // see note 1
        return ResponseEntity
            .status(HttpStatus.CREATED)                 
            .body(this.userService.chkCredentials(accessKey, secretKey, timestamp));
    }
    catch(ChekingCredentialsFailedException e) {
        e.printStackTrace(); // see note 2
        return ResponseEntity
            .status(HttpStatus.FORBIDDEN)
            .body("Error Message");
    }
}

Note 1: You don't have to use the ResponseEntity builder but I find it helps with keeping the code readable. It also helps remembering, which data a response for a specific HTTP status code should include. For example, a response with the status code 201 should contain a link to the newly created resource in the Location header (see Status Code Definitions). This is why Spring offers the convenient build method ResponseEntity.created(URI).

Note 2: Don't use printStackTrace(), use a logger instead.

Provide an @ExceptionHandler

Remove the try-catch block from your method and let it throw the exception. Then create another method in a class annotated with @ControllerAdvice like this:

@ControllerAdvice
public class ExceptionHandlerAdvice {

    @ExceptionHandler(ChekingCredentialsFailedException.class)
    public ResponseEntity handleException(ChekingCredentialsFailedException e) {
        // log exception
        return ResponseEntity
                .status(HttpStatus.FORBIDDEN)
                .body("Error Message");
    }        
}

Note that methods which are annotated with @ExceptionHandler are allowed to have very flexible signatures. See the Javadoc for details.

Previous answer didn't work for me.

But this worked perfectly. Convert Data URI to File then append to FormData

here is an example, where the length of the array is changed during execution of the loop

import java.util.ArrayList;
public class VariableArrayLengthLoop {

public static void main(String[] args) {

    //create new ArrayList
    ArrayList<String> aListFruits = new ArrayList<String>();

    //add objects to ArrayList
    aListFruits.add("Apple");
    aListFruits.add("Banana");
    aListFruits.add("Orange");
    aListFruits.add("Strawberry");

    //iterate ArrayList using for loop
    for(int i = 0; i < aListFruits.size(); i++){

        System.out.println( aListFruits.get(i) + " i = "+i );
         if ( i == 2 ) {
                aListFruits.add("Pineapple");  
                System.out.println( "added now a Fruit to the List "); 
                }
        }
    }
}

James K, I'm sorry I was wrong in a fair portion of what I said. The test I did was the following:

@ECHO OFF
(
  :: But
   : neither
  :: does
   : this
  :: also.
)

This meets your description of alternating but fails with a ") was unexpected at this time." error message.

I did some farther testing today and found that alternating isn't the key but it appears the key is having an even number of lines, not having any two lines in a row starting with double colons (::) and not ending in double colons. Consider the following:

@ECHO OFF
(
   : But
   : neither
   : does
   : this
   : cause
   : problems.
)

This works!

But also consider this:

@ECHO OFF
(
   : Test1
   : Test2
   : Test3
   : Test4
   : Test5
   ECHO.
)

The rule of having an even number of comments doesn't seems to apply when ending in a command.

Unfortunately this is just squirrelly enough that I'm not sure I want to use it.

Really, the best solution, and the safest that I can think of, is if a program like Notepad++ would read REM as double colons and then would write double colons back as REM statements when the file is saved. But I'm not aware of such a program and I'm not aware of any plugins for Notepad++ that does that either.

If you want a destructive backspace, you'll need something like

"\b \b"

i.e. a backspace, a space, and another backspace.

found a paper at: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1924044 that suggests a formula to calculate the downloads:

d_iPad=13,516*rank^(-0.903)
d_iPhone=52,958*rank^(-0.944)

Though not exactly what the Q was asking for, I've built one that is similar but uses named placeholders instead of numbered. I personally prefer having named arguments and just send in an object as an argument to it (more verbose, but easier to maintain).

String.prototype.format = function (args) {
    var newStr = this;
    for (var key in args) {
        newStr = newStr.replace('{' + key + '}', args[key]);
    }
    return newStr;
}

Here's an example usage...

alert("Hello {name}".format({ name: 'World' }));

Project -> Clean

can at least sometimes be sufficient to resolve the matter.

If you really have to, you can make conditional comments work by adding the following line to <head>:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">

Useful information for some:

On Linux, installing PyCharm as a snap package automatically creates the command-line launcher named pycharm-professional, pycharm-community, or pycharm-educational. The Tools | Create Command-line Launcher command is therefore not available.

How about this:

When the page first loads, do this:

var myTable = document.getElementById("myTable");
myTable.oldHTML=myTable.innerHTML;

Then when you want to clear the table:

myTable.innerHTML=myTable.oldHTML;

The result will be your header row(s) if that's all you started with, the performance is dramatically faster than looping.

Use FireFox or any other browser instead of Chrome if you want to test it on your development environment, for production there is no way except using https.

For development environment just open http://localhost:8100/ on FireFox and alas no such error.

Do you mean finding a stack trace of the thrown exception location? That's either Debug/Exceptions, or better - Ctrl-Alt-E. Set filters for the exceptions you want to break on.

There's even a way to reconstruct the thrower stack after the exception was caught, but it's really unpleasant. Much, much easier to set a break on the throw.

Use the elevation property for shadow affect:

<YourView
    ...
    android:elevation="3dp"/>

You're on the right track. Here's a corrected version:

char str[10];
int n;

printf("type a string: ");
scanf("%s %d", str, &n);

printf("%s\n", str);
printf("%d\n", n);

Let's talk through the changes:

1. allocate an int (n) to store your number in
2. tell scanf to read in first a string and then a number (%d means number, as you already knew from your printf

That's pretty much all there is to it. Your code is a little bit dangerous, still, because any user input that's longer than 9 characters will overflow str and start trampling your stack.

Build.VERSION.RELEASE;

That will give you the actual numbers of your version; aka 2.3.3 or 2.2. The problem with using Build.VERSION.SDK_INT is if you have a rooted phone or custom rom, you could have a non standard OS (aka my android is running 2.3.5) and that will return a null when using Build.VERSION.SDK_INT so Build.VERSION.RELEASE will work no matter using standard Android version or not !

To use it, you could just do this;

String androidOS = Build.VERSION.RELEASE;

$('#saveBtn').off('click').on('click',function(){
   saveQuestion(id)
});

Your server running on port 5432 but in the properties, the port is set to 5433.

You must go to pgAdmin, click on database version, ex: PostgresSQL 10 and edit properties.

A new window appears and you need to change the port to 5432 [this is default port].

There is no algorithm which can find all the cycles in a directed graph in polynomial time. Suppose, the directed graph has n nodes and every pair of the nodes has connections to each other which means you have a complete graph. So any non-empty subset of these n nodes indicates a cycle and there are 2^n-1 number of such subsets. So no polynomial time algorithm exists. So suppose you have an efficient (non-stupid) algorithm which can tell you the number of directed cycles in a graph, you can first find the strong connected components, then applying your algorithm on these connected components. Since cycles only exist within the components and not between them.

The timer has special functions.

2. Change the time interval

As of ES2015, property order is guaranteed for certain methods that iterate over properties. but not others. Unfortunately, the methods which are not guaranteed to have an order are generally the most often used:

• Object.keys, Object.values, Object.entries
• for..in loops
• JSON.stringify

But, as of ES2020, property order for these previously untrustworthy methods will be guaranteed by the specification to be iterated over in the same deterministic manner as the others, due to to the finished proposal: for-in mechanics.

Just like with the methods which have a guaranteed iteration order (like Reflect.ownKeys and Object.getOwnPropertyNames), the previously-unspecified methods will also iterate in the following order:

• Numeric array keys, in ascending numeric order
• All other non-Symbol keys, in insertion order
• Symbol keys, in insertion order

This is what pretty much every implementation does already (and has done for many years), but the new proposal has made it official.

Although the current specification leaves for..in iteration order "almost totally unspecified, real engines tend to be more consistent:"

The lack of specificity in ECMA-262 does not reflect reality. In discussion going back years, implementors have observed that there are some constraints on the behavior of for-in which anyone who wants to run code on the web needs to follow.

Because every implementation already iterates over properties predictably, it can be put into the specification without breaking backwards compatibility.

There are a few weird cases which implementations currently do not agree on, and in such cases, the resulting order will continue be unspecified. For property order to be guaranteed:

Neither the object being iterated nor anything in its prototype chain is a proxy, typed array, module namespace object, or host exotic object.

Neither the object nor anything in its prototype chain has its prototype change during iteration.

Neither the object nor anything in its prototype chain has a property deleted during iteration.

Nothing in the object's prototype chain has a property added during iteration.

No property of the object or anything in its prototype chain has its enumerability change during iteration.

No non-enumerable property shadows an enumerable one.

This matches a word from any length:

var phrase = "an important number comes after this: 123456";
var word = "this: ";
var number = phrase.substr(phrase.indexOf(word) + word.length);
// number = 123456

Could you use the SQLPATH environment variable to tell sqlplus where to look for the scripts you are trying to run? I believe you could use HOST to set SQLPATH in the script too.

There could potentially be problems if two scripts have the same name and both directories are in the SQLPATH.

What worked for me is inserting a column before the first column and deleting it immediately. Basically, do a change that will affect all the cells in the worksheet that will trigger recalculation.

This also works:

I just changed with this.state.color==='white'?'black':'white'.

You can also pick the color from drop-down values and update in place of 'black';

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

std::map will sort its elements by keys. It doesn't care about the values when sorting.

You can use std::vector<std::pair<K,V>> then sort it using std::sort followed by std::stable_sort:

std::vector<std::pair<K,V>> items;

//fill items

//sort by value using std::sort
std::sort(items.begin(), items.end(), value_comparer);

//sort by key using std::stable_sort
std::stable_sort(items.begin(), items.end(), key_comparer);

Note that while std::sort is chosen for performance reason, std::stable_sort is needed for correct ordering, as you want the order-by-value to be preserved.

@gsf noted in the comment, you could use only std::sort if you choose a comparer which compares values first, and IF they're equal, sort the keys.

auto cmp = [](std::pair<K,V> const & a, std::pair<K,V> const & b) 
{ 
     return a.second != b.second?  a.second < b.second : a.first < b.first;
};
std::sort(items.begin(), items.end(), cmp);

That should be efficient.

But wait, there is a better approach: store std::pair<V,K> instead of std::pair<K,V> and then you don't need any comparer at all — the standard comparer for std::pair would be enough, as it compares first (which is V) first then second which is K:

std::vector<std::pair<V,K>> items;
//...
std::sort(items.begin(), items.end());

That should work great.

verse = "If you can keep your head when all about you\n Are losing theirs and blaming it on you,\nIf you can trust yourself when all men doubt you,\n But make allowance for their doubting too;\nIf you can wait and not be tired by waiting,\n Or being lied about, don’t deal in lies,\nOr being hated, don’t give way to hating,\n And yet don’t look too good, nor talk too wise:"

enter code here

print(verse)
#1. What is the length of the string variable verse?
verse_length = len(verse)
print("The length of verse is: {}".format(verse_length))
#2. What is the index of the first occurrence of the word 'and' in verse?
index = verse.find("and")
print("The index of the word 'and' in verse is {}".format(index))

Try this regular expression:

\w*Id\b

\w* allows word characters in front of Id and the \b ensures that Id is at the end of the word (\b is word boundary assertion).

As well as escaping quotes with backslashes, also see SO question 2911073 which explains how you could alternatively use double-quoting in a @-prefixed string:

string msg = @"I want to learn ""c#""";

The solution by James works for all Platforms.

Alternatively on Windows you can also add the following just before you return from main function:

  system("pause");

This will run the pause command which waits till you press a key and also displays a nice message Press any key to continue . . .

DateTime.Now will not work, use DateTime.Today instead.

The question has been answered. But I wanted to add a concrete example.

class Point{

public:
      Point(int theX, int theY) :x(theX), y(theY)
      {}
      // Print the object
      friend ostream& operator <<(ostream& outputStream, const Point& p);
private:
      int x;
      int y;
};

ostream& operator <<(ostream& outputStream, const Point& p){
       int posX = p.x;
       int posY = p.y;

       outputStream << "x="<<posX<<","<<"y="<<posY;
      return outputStream;
}

This example requires understanding operator overload.

Another way (worked for 2015) is open "Install/remove programs" (Apps & features), find Visual Studio, select Modify. In opened window, press Modify, check

• Languages -> Visual C++ -> Common tools for Visual C++
• Windows and web development -> Tools for universal windows apps -> Tools (1.4.1) and Windows 10 SDK ([version])
• Windows and web development -> Tools for universal windows apps -> Windows 10 SDK ([version])

and install. Then right click on solution -> Re-target and it will compile

Perhaps I'm misunderstanding the intent of your question, so correct me if I'm wrong, but can't you apply the culture settings globally once, and then not worry about customizing every write statement?

Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-GB");

I think what he is trying to say is to use the getContentPane().setBackground(Color.the_Color_you_want_here)

but if u want to set the color to any other then the JFrame, you use the object.setBackground(Color.the_Color_you_want_here)

Eg:

jPanel.setbackground(Color.BLUE)

If you're not joining two dictionaries, but adding new key-value pairs to a dictionary, then using the subscript notation seems like the best way.

import timeit

timeit.timeit('dictionary = {"karga": 1, "darga": 2}; dictionary.update({"aaa": 123123, "asd": 233})')
>> 0.49582505226135254

However, if you'd like to add, for example, thousands of new key-value pairs, you should consider using the update() method.

You need to access the page_source property:

from selenium import webdriver

browser = webdriver.Firefox()
browser.get("http://example.com")

html_source = browser.page_source
if "whatever" in html_source:
    # do something
else:
    # do something else

Yes, add the -Force parameter.

copy-item $from $to -Recurse -Force

You could write a directive for this, which simply assigns the (jqLite) element to the scope using an attribute-given name.

Here is the directive:

app.directive("ngScopeElement", function () {
  var directiveDefinitionObject = {

    restrict: "A",

    compile: function compile(tElement, tAttrs, transclude) {
      return {
          pre: function preLink(scope, iElement, iAttrs, controller) {
            scope[iAttrs.ngScopeElement] = iElement;
          }
        };
    }
  };

  return directiveDefinitionObject;
});

Usage:

app.directive("myDirective", function() {
    return {
        template: '<div><ul ng-scope-element="list"><li ng-repeat="item in items"></ul></div>',
        link: function(scope, element, attrs) {
            scope.list[0] // scope.list is the jqlite element, 
                          // scope.list[0] is the native dom element
        }
    }
});

Some remarks:

• Due to the compile and link order for nested directives you can only access scope.list from myDirectives postLink-Function, which you are very likely using anyway
• ngScopeElement uses a preLink-function, so that directives nested within the element having ng-scope-element can already access scope.list
• not sure how this behaves performance-wise

Writing a decorator that works with and without parameter is a challenge because Python expects completely different behavior in these two cases! Many answers have tried to work around this and below is an improvement of answer by @norok2. Specifically, this variation eliminates the use of locals().

Following the same example as given by @norok2:

import functools

def multiplying(f_py=None, factor=1):
    assert callable(f_py) or f_py is None
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            return factor * func(*args, **kwargs)
        return wrapper
    return _decorator(f_py) if callable(f_py) else _decorator


@multiplying
def summing(x): return sum(x)

print(summing(range(10)))
# 45


@multiplying()
def summing(x): return sum(x)

print(summing(range(10)))
# 45


@multiplying(factor=10)
def summing(x): return sum(x)

print(summing(range(10)))
# 450

Play with this code.

The catch is that the user must supply key,value pairs of parameters instead of positional parameters and the first parameter is reserved.

You should declare your method first in void initState(), so when the first time pages has been loaded, it will init your method first, hope it can help

This should do what you want:

<div class="comeBack_up" *ngIf="(previous_info | json) != ({} | json)">

or shorter

<div class="comeBack_up" *ngIf="(previous_info | json) != '{}'">

Each {} creates a new instance and ==== comparison of different objects instances always results in false. When they are convert to strings === results to true

Plunker example

Added MSSQLSERVER full access to the folder, diskadmin and bulkadmin server roles.

In my c# application, when preparing for the bulk insert command,

string strsql = "BULK INSERT PWCR_Contractor_vw_TEST FROM '" + strFileName + "' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";

And I get this error - Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 8 (STATUS).

I looked at my logfile and found that the terminator becomes ' ' instead of '\n'. The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error:

Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)". Query :BULK INSERT PWCR_Contractor_vw_TEST FROM 'G:\NEWSTAGEWWW\CalAtlasToPWCR\Results\parsedRegistration.csv' WITH (FIELDTERMINATOR = ',', **ROWTERMINATOR = ''**)

So I added extra escape to the rowterminator - string strsql = "BULK INSERT PWCR_Contractor_vw_TEST FROM '" + strFileName + "' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";

And now it inserts successfully.

Bulk Insert SQL -   --->  BULK INSERT PWCR_Contractor_vw_TEST FROM 'G:\\NEWSTAGEWWW\\CalAtlasToPWCR\\Results\\parsedRegistration.csv' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
Bulk Insert to PWCR_Contractor_vw_TEST successful...  --->  clsDatase.PerformBulkInsert

Made it.

from datetime import datetime
dateNow = datetime.now().strftime('%Y%m%d')

It is likely that the delete statement will affect a large fraction of the total rows in the table. Eventually this might lead to a table lock being acquired when deleting. Holding on to a lock (in this case row- or page locks) and acquiring more locks is always a deadlock risk. However I can't explain why the insert statement leads to a lock escalation - it might have to do with page splitting/adding, but someone knowing MySQL better will have to fill in there.

For a start it can be worth trying to explicitly acquire a table lock right away for the delete statement. See LOCK TABLES and Table locking issues.

You can simply pass your data frame into the following function:

rotate_x <- function(data, column_to_plot, labels_vec, rot_angle) {
    plt <- barplot(data[[column_to_plot]], col='steelblue', xaxt="n")
    text(plt, par("usr")[3], labels = labels_vec, srt = rot_angle, adj = c(1.1,1.1), xpd = TRUE, cex=0.6) 
}

Usage:

rotate_x(mtcars, 'mpg', row.names(mtcars), 45)

You can change the rotation angle of the labels as needed.

This is the way I did it and it worked fine for me. (done on Tomcat 7.x)

Add a <context> to the tomcat/conf/server.xml file.

Windows example:

<Context docBase="c:\Documents and Settings\The User\images" path="/project/images" />

Linux example:

<Context docBase="/var/project/images" path="/project/images" />

Like this (in context):

<Server port="8025" shutdown="SHUTDOWN">
 ...
  <Service name="Catalina">
    ...
    <Engine defaultHost="localhost" name="Catalina">
     ...
     <Host appBase="webapps"
      autoDeploy="false" name="localhost" unpackWARs="true"
      xmlNamespaceAware="false" xmlValidation="false">
      ...
      <!--MAGIC LINE GOES HERE-->
       <Context  docBase="/var/project/images" path="/project/images" />

      </Host>
    </Engine>
  </Service>
</Server>

In this way, you should be able to find the files (e.g. /var/project/images/NameOfImage.jpg) under:

http://localhost:8080/project/images/NameOfImage.jpg 

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

Better you can query in matching array element using $slice is it helpful to returning the significant object in an array.

db.test.find({"shapes.color" : "blue"}, {"shapes.$" : 1})

$slice is helpful when you know the index of the element, but sometimes you want whichever array element matched your criteria. You can return the matching element with the $ operator.

Use the recursive switch --recursive (-R)

svn revert -R .

There's now a doesObjectExist method in the official Java API.

Enjoy!

H?llo from 2020. Let me bring String.prototype.matchAll() to your attention:

let regexp = /(?:&|&)?([^=]+)=([^&]+)/g;
let str = '1111342=Adam%20Franco&348572=Bob%20Jones';

for (let match of str.matchAll(regexp)) {
    let [full, key, value] = match;
    console.log(key + ' => ' + value);
}

Outputs:

1111342 => Adam%20Franco
348572 => Bob%20Jones

Checkout your SDK manager in Android studio, if you have partially installed sdk. Install SDK completely and try running your code.

Another good alternative is http_build_query

$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&');

Will print

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor

More info here http://php.net/manual/en/function.http-build-query.php

Access requires parentheses in the FROM clause for queries which include more than one join. Try it this way ...

FROM
    ((tbl_employee
    INNER JOIN tbl_netpay
    ON tbl_employee.emp_id = tbl_netpay.emp_id)
    INNER JOIN tbl_gross
    ON tbl_employee.emp_id = tbl_gross.emp_ID)
    INNER JOIN tbl_tax
    ON tbl_employee.emp_id = tbl_tax.emp_ID;

If possible, use the Access query designer to set up your joins. The designer will add parentheses as required to keep the db engine happy.

Between all of the responses here, there are lots of good things to try. For completeness, if you

ssh vagrant@localhost -p 2222

as @Bizmate suggests, and it fails, be sure you have

AllowUsers vagrant

in the /etc/ssh/sshd_config of your guest/vagrant machine.

This is indeed rather odd.

If aSourceDictionary were a dictionary, I don't believe it is possible for your code to fail in the manner you describe.

This leads to two hypotheses:

1. The code you're actually running is not identical to the code in your question (perhaps an earlier or later version?)

2. aSourceDictionary is in fact not a dictionary, but is some other structure (for example, a list).

A working code:

private void changeScreenOrientation() {
    int orientation = yourActivityName.this.getResources().getConfiguration().orientation;
    if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        showMediaDescription();
    } else {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        hideMediaDescription();
    }
    if (Settings.System.getInt(getContentResolver(),
            Settings.System.ACCELEROMETER_ROTATION, 0) == 1) {
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
            }
        }, 4000);
    }
}

call this method in your button click

I was just inspired by your solution and tried another way.

Please try to add tableView.reloadData() to viewDidAppear().

This works for me.

I think the things behind scrolling is "the same" as reloadData. When you scroll the screen, it's like calling reloadData() when viewDidAppear .

If this works, plz reply this answer so I could be sure of this solution.

Using standard JSF API, add the client ID to PartialViewContext#getRenderIds().

FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add("foo:bar");

Using PrimeFaces specific API, use PrimeFaces.Ajax#update().

PrimeFaces.current().ajax().update("foo:bar");

Or if you're not on PrimeFaces 6.2+ yet, use RequestContext#update().

RequestContext.getCurrentInstance().update("foo:bar");

If you happen to use JSF utility library OmniFaces, use Ajax#update().

Ajax.update("foo:bar");

Regardless of the way, note that those client IDs should represent absolute client IDs which are not prefixed with the NamingContainer separator character like as you would do from the view side on.

The problem I had was using the wrong jQuery identifier.

You can upload data and files with one form using ajax.

PHP + HTML

<?php

print_r($_POST);
print_r($_FILES);
?>

<form id="data" method="post" enctype="multipart/form-data">
    <input type="text" name="first" value="Bob" />
    <input type="text" name="middle" value="James" />
    <input type="text" name="last" value="Smith" />
    <input name="image" type="file" />
    <button>Submit</button>
</form>

jQuery + Ajax

$("form#data").submit(function(e) {
    e.preventDefault();    
    var formData = new FormData(this);

    $.ajax({
        url: window.location.pathname,
        type: 'POST',
        data: formData,
        success: function (data) {
            alert(data)
        },
        cache: false,
        contentType: false,
        processData: false
    });
});

Short Version

$("form#data").submit(function(e) {
    e.preventDefault();
    var formData = new FormData(this);    

    $.post($(this).attr("action"), formData, function(data) {
        alert(data);
    });
});

function countWords(str) {
    var regEx = /([^\u0000-\u007F]|\w)+/g;  
    return str.match(regEx).length;
}

Explanation:

/([^\u0000-\u007F]|\w) matches word characters - which is great -> regex does the heavy lifting for us. (This pattern is based on the following SO answer: https://stackoverflow.com/a/35743562/1806956 by @Landeeyo)

+ matches the whole string of the previously specified word characters - so we basically group word characters.

/g means it keeps looking till the end.

str.match(regEx) returns an array of the found words - so we count its length.

int i = 7122960;
decimal d = (decimal)i / 100;

I was not satisfied, so I finally used this:

>>> a=numpy.array([[1,2,3],[4,5,6]])
>>> a
array([[1, 2, 3],
       [4, 5, 6]])

>>> tuple(a.reshape(1, -1)[0])
(1, 2, 3, 4, 5, 6)

I don't know if it's quicker, but it looks more effective ;)

You are using POST method, but are you providing an array of data? E.g.

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

Looking for About Phone in Settings. And scroll down till you see Build number. Tap here till you see Toast message tell you have just enable developer mode.

Back to settings, you can see options: "Developer options"

HTTP may not have an upper limit, but webservers may have one. In ASP.NET there is a default accept-limit of 4 MB, but you (the developer/webmaster) can change that to be higher or lower.

Use NULLIF(exp,0) but in this way - NULLIF(ISNULL(exp,0),0)

NULLIF(exp,0) breaks if exp is null but NULLIF(ISNULL(exp,0),0) will not break

Another alternative is using the fs-promise module that provides promisified versions of the fs-extra modules

you could then write like this example:

const { remove, mkdirp, writeFile, readFile } = require('fs-promise')
const { join, dirname } = require('path')

async function createAndRemove() {
  const content = 'Hello World!'
  const root = join(__dirname, 'foo')
  const file = join(root, 'bar', 'baz', 'hello.txt')

  await mkdirp(dirname(file))
  await writeFile(file, content)
  console.log(await readFile(file, 'utf-8'))
  await remove(join(__dirname, 'foo'))
}

createAndRemove().catch(console.error)

note: async/await requires a recent nodejs version (7.6+)

Summary:

Use is when you want to check against an object's identity (e.g. checking to see if var is None). Use == when you want to check equality (e.g. Is var equal to 3?).

Explanation:

You can have custom classes where my_var == None will return True

e.g:

class Negator(object):
    def __eq__(self,other):
        return not other

thing = Negator()
print thing == None    #True
print thing is None    #False

is checks for object identity. There is only 1 object None, so when you do my_var is None, you're checking whether they actually are the same object (not just equivalent objects)

In other words, == is a check for equivalence (which is defined from object to object) whereas is checks for object identity:

lst = [1,2,3]
lst == lst[:]  # This is True since the lists are "equivalent"
lst is lst[:]  # This is False since they're actually different objects

If you are using NumPy, you can concatenate two arrays of compatible dimensions with this command:

numpy.concatenate([a,b])

Fail module works great! Thanks.

I had to define my fact before checking it, otherwise I'd get an undefined variable error.

And I had issues when doing setting the fact with quotes and without spaces.

This worked:

set_fact: flag="failed"

This threw errors:

set_fact: flag = failed 

1. Constant extrapolation

You can use interp function from scipy, it extrapolates left and right values as constant beyond the range:

>>> from scipy import interp, arange, exp
>>> x = arange(0,10)
>>> y = exp(-x/3.0)
>>> interp([9,10], x, y)
array([ 0.04978707,  0.04978707])

2. Linear (or other custom) extrapolation

You can write a wrapper around an interpolation function which takes care of linear extrapolation. For example:

from scipy.interpolate import interp1d
from scipy import arange, array, exp

def extrap1d(interpolator):
    xs = interpolator.x
    ys = interpolator.y

    def pointwise(x):
        if x < xs[0]:
            return ys[0]+(x-xs[0])*(ys[1]-ys[0])/(xs[1]-xs[0])
        elif x > xs[-1]:
            return ys[-1]+(x-xs[-1])*(ys[-1]-ys[-2])/(xs[-1]-xs[-2])
        else:
            return interpolator(x)

    def ufunclike(xs):
        return array(list(map(pointwise, array(xs))))

    return ufunclike

extrap1d takes an interpolation function and returns a function which can also extrapolate. And you can use it like this:

x = arange(0,10)
y = exp(-x/3.0)
f_i = interp1d(x, y)
f_x = extrap1d(f_i)

print f_x([9,10])

Output:

[ 0.04978707  0.03009069]

I agree with Rup. I guess the main reason is to avoid confusion on relative paths. I think wordpress can work from scratch with relative paths but the problem might come when using multiple plugins, how the theme is configured etc.

I've once used this plugin for relative paths, when working on testing servers:

Root Relative URLs
Converts all URLs to root-relative URLs for hosting the same site on multiple IPs, easier production migration and better mobile device testing.

You could also just use the NSUUID API:

let uuid = NSUUID()

If you want to get the string value back out, you can use uuid.UUIDString.

Note that NSUUID is available from iOS 6 and up.

There is an official Microsoft answer to this question at the following knowledge base article:

Article ID: 318785 - Last Review: November 7, 2008 - Revision: 20.1 How to determine which versions of the .NET Framework are installed and whether service packs have been applied

Unfortunately, it doesn't appear to work, because the mscorlib.dll version in the 2.0 directory has a 2.0 version, and there is no mscorlib.dll version in either the 3.0 or 3.5 directories even though 3.5 SP1 is installed ... why would the official Microsoft answer be so misinformed?

(.*?) matches anything - I've been using it for years.

You can use nircmd project here: http://www.nirsoft.net/utils/nircmd.html

Example code:

nircmd win move ititle "cmd.exe" 5 5 10 10
nircmd win setsize ititle "cmd.exe" 30 30 100 200
nircmd cmdwait 1000 win setsize ititle "cmd.exe" 30 30 1000 600

I see three issues:

1. The display of the Select2 control is not refreshed when its value is changed due to a form reset.
2. The "All" option does not have a value attribute.
3. The "All" option is disabled.

First, I recommend that you use the setTimeout function to ensure that code is executed after the form reset is complete.

You could execute code when the button is clicked:

$('#searchclear').click(function() {
    setTimeout(function() {
        // Code goes here.
    }, 0);
});

Or when the form is reset:

$('form').on('reset', function() {
    setTimeout(function() {
        // Code goes here.
    }, 0);
});

As for what code to use:

Since the "All" option is disabled, the form reset does not make it the selected value. Therefore, you must explicitly set it to be the selected value. The way to do that is with the Select2 "val" function. And since the "All" option does not have a value attribute, its value is the same as its text, which is "All". Therefore, you should use the code given by thtsigma in the selected answer:

$("#d").select2('val', 'All');

If the attribute value="" were to be added to the "All" option, then you could use the code given by Daniel Dener:

$("#d").select2('val', '');

If the "All" option was not disabled, then you would just have to force the Select2 to refresh, in which case you could use:

$('#d').change();

Note: The following code by Lenart is a way to clear the selection, but it does not cause the "All" option to be selected:

$('#d').select2('data', null)

I know there are a few configurations to use the static contents, but my solution is that I just create a bulk web-application folder within your tomcat. This "bulk webapp" is only serving all the static-contents without serving apps. This is pain-free and easy solution for serving static contents to your actual spring webapp.

For example, I'm using two webapp folders on my tomcat.

1. springapp: it is running only spring web application without static-contents like imgs, js, or css. (dedicated for spring apps.)
2. resources: it is serving only the static contents without JSP, servlet, or any sort of java web application. (dedicated for static-contents)

If I want to use javascript, I simply add the URI for my javascript file.

EX> /resources/path/to/js/myjavascript.js

For static images, I'm using the same method.

EX> /resources/path/to/img/myimg.jpg

Last, I put "security-constraint" on my tomcat to block the access to actual directory. I put "nobody" user-roll to the constraint so that the page generates "403 forbidden error" when people tried to access the static-contents path.

So far it works very well for me. I also noticed that many popular websites like Amazon, Twitter, and Facebook they are using different URI for serving static-contents. To find out this, just right click on any static content and check their URI.

For me, the reason was apparently different, and the error message misleading.

With just this in my build.gradle, it would complain that slf4j was missing at the beginning of the log, but still log things, albeit in a poor format:

    compile 'log4j:log4j:1.2.17'

Adding that dependency would cause the discussed "no appenders could be found" error message for me, even though I had defined them in src/main/java/log4j.properties:

    compile 'log4j:log4j:1.2.17'
    compile 'org.slf4j:slf4j-log4j12:1.7.25'

Finally, adding the following dependency (which I only guessed at by copycatting it from another project) resolved the issue:

    compile 'log4j:log4j:1.2.17'
    compile 'org.slf4j:slf4j-log4j12:1.7.25'
    compile 'commons-logging:commons-logging:1.2'

I don't know why, but with this it works. Any insights on that?

You want to navigate through the entire linked list using a loop and checking the "next" value for each node. The last node will be the one whose next value is null. Simply make this node's next value a new node which you create with the input data.

node temp = first; // starts with the first node.

    while (temp.next != null)
    {
       temp = temp.next;
    }

temp.next = new Node(header, x);

That's the basic idea. This is of course, pseudo code, but it should be simple enough to implement.

LIMIT is usually applied as the last operation, so the result will first be sorted and then limited to 20. In fact, sorting will stop as soon as first 20 sorted results are found.

This is a great article for syntax needed to create new objects from a LINQ query.

But, if the assignments to fill in the fields of the object are anything more than simple assignments, for example, parsing strings to integers, and one of them fails, it is not possible to debug this. You can not create a breakpoint on any of the individual assignments.

And if you move all the assignments to a subroutine, and return a new object from there, and attempt to set a breakpoint in that routine, you can set a breakpoint in that routine, but the breakpoint will never be triggered.

So instead of:

var query2 = from c in doc.Descendants("SuggestionItem")
                select new SuggestionItem
                       { Phrase = c.Element("Phrase").Value
                         Blocked = bool.Parse(c.Element("Blocked").Value),
                         SeenCount = int.Parse(c.Element("SeenCount").Value)
                       };

Or

var query2 = from c in doc.Descendants("SuggestionItem")
                         select new SuggestionItem(c);

I instead did this:

List<SuggestionItem> retList = new List<SuggestionItem>();

var query = from c in doc.Descendants("SuggestionItem") select c;

foreach (XElement item in query)
{
    SuggestionItem anItem = new SuggestionItem(item);
    retList.Add(anItem);
}

This allowed me to easily debug and figure out which assignment was failing. In this case, the XElement was missing a field I was parsing for to set in the SuggestionItem.

I ran into these gotchas with Visual Studio 2017 while writing unit tests for a new library routine.

Here's a simple example that waits for a tread to finish, within the same class. It also makes a call to another class in the same namespace. I included the "using" statements so it can execute as a Windows Forms form as long as you create button1.

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Threading;

namespace ClassCrossCall
{

    public partial class Form1 : Form
    {
        int number = 0; // This is an intentional problem, included
                        // for demonstration purposes
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            button1.Text = "Initialized";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            button1.Text = "Clicked";
            button1.Refresh();
            Thread.Sleep(400);
            List<Task> taskList = new List<Task>();
            taskList.Add(Task.Factory.StartNew(() => update_thread(2000)));
            taskList.Add(Task.Factory.StartNew(() => update_thread(4000)));
            Task.WaitAll(taskList.ToArray());
            worker.update_button(this, number);
        }

        public void update_thread(int ms)
        {
            // It's important to check the scope of all variables
            number = ms; // This could be either 2000 or 4000. Race condition.
            Thread.Sleep(ms);
        }
    }

    class worker
    {
        public static void update_button(Form1 form, int number)
        {
            form.button1.Text = $"{number}";
        }
    }
}

This happened to me when I accidentally defined two entities with the same persistent database table. In one of the tables the column in question did exist, in the other not. When attempting to persist an object (of the type referring to the wrong underlying database table), this error occurred.

Hope you been through this , if not please read.

https://developer.android.com/reference/android/os/AsyncTask

Depending on the nature of result data, you should choose best possible option you can think of.

It is a great choice to use an Interface

some other options would be..

• If the AsyncTask class is defined inside the very class you want to use the result in.Use a static global variable or get() , use it from outer class (volatile variable if necessary). but should be aware of the AsyncTask progress or should at least make sure that it have finished the task and result is available through global variable / get() method. you may use polling, onProgressUpdate(Progress...), synchronization or interfaces (Which ever suits best for you)

• If the Result is compatible to be a sharedPreference entry or it is okay to be saved as a file in the memory you could save it even from the background task itself and could use the onPostExecute() method
  to get notified when the result is available in the memory.

• If the string is small enough, and is to be used with start of an activity. it is possible to use intents (putExtra()) within onPostExecute() , but remember that static contexts aren't that safe to deal with.

• If possible, you can call a static method from the onPostExecute() method, with the result being your parameter

Alternatively, you can use React conditional rendering.

import { Redirect } from "react-router";
import React, { Component } from 'react';

class UserSignup extends Component {
  constructor(props) {
    super(props);
    this.state = {
      redirect: false
    }
  }
render() {
 <React.Fragment>
   { this.state.redirect && <Redirect to="/signin" /> }   // you will be redirected to signin route
}
</React.Fragment>
}

That's exactly how you use it. There is a possibility that the address you have does not correspond to something directly in your source code though.

For example:

$ cat t.c
#include <stdio.h>
int main()
{
    printf("hello\n");
    return 0;
}
$ gcc -g t.c
$ addr2line -e a.out 0x400534
/tmp/t.c:3
$ addr2line -e a.out 0x400550
??:0

0x400534 is the address of main in my case. 0x400408 is also a valid function address in a.out, but it's a piece of code generated/imported by GCC, that has no debug info. (In this case, __libc_csu_init. You can see the layout of your executable with readelf -a your_exe.)

Other times when addr2line will fail is if you're including a library that has no debug information.

#include <stdio_ext.h>

and then use function

__fpurge(stdin)

Groovy

You can subtract a substring from a string using a regular expression in groovy:

String unquotedString = theString - ~/^"/ - ~/"$/

What is a plain English explanation of “Big O” notation?

I would like to stress that the driving motive for “Big O” notation is one thing, when an input size of algorithm gets too big some parts (i.e constants, coefficients, terms )of the equation describing the measure of the algorithm becomes so insignificant that we ignore them. The parts of equation that survives after ignoring some of its parts is termed as the “Big O” notation of the algorithm.

So if the input size is NOT too big the idea of “Big O” notation( upper bound ) will be unimportant.

Les say you want to quantify the performance of the following algorithm

int sumArray (int[] nums){
    int sum=0;   // taking initialization and assignments n=1
    for(int i=0;nums.length;i++){
        sum += nums[i]; // taking initialization and assignments n=1
    }
    return sum;
}

In above algorithm, lets say you find out T(n) as follows (time complexity):

T(n) = 2*n + 2

To find its “Big O” notation, we need to consider very big input size:

n= 1,000,000   -> T(1,000,000) = 2,000,002
n=1,000,000,000  -> T(1,000,000,000) = 2,000,000,002
n=10,000,000,000  -> T(10,000,000,000) = 20,000,000,002

Lets give this similar inputs for another function F(n) = n

n= 1,000,000   -> F(1,000,000) = 1,000,000 
n=1,000,000,000  -> F(1,000,000,000) = 1,000,000,000
n=10,000,000,000  -> F(10,000,000,000) = 10,000,000,000

As you can see as input size get too big the T(n) approximately equal to or getting closer to F(n), so the constant 2 and the coefficient 2 are becoming too insignificant, now the idea of Big O” notation comes in,

O(T(n)) = F(n)
O(T(n)) = n

We say the big O of T(n) is n, and the notation is O(T(n)) = n, it is the upper bound of T(n) as n gets too big. the same step applies for other algorithms.

Try to delete the temp files

cd /tmp/
rm -r *

If the image isn't that big, and if there's a good chance you'll be re-using the image often, and if you don't have too many of them, and if the images are not secret (meaning it's no big deal if one user could potentially see another person's image)...

Lots of "if"s here, so there's a good chance this is a bad idea:

You can store the image bytes in Cache for a short time, and make an image tag pointed toward an action method, which in turn reads from the cache and spits out your image. This will allow the browser to cache the image appropriately.

// In your original controller action
HttpContext.Cache.Add("image-" + model.Id, model.ImageBytes, null,
    Cache.NoAbsoluteExpiration, TimeSpan.FromMinutes(1),
    CacheItemPriority.Normal, null);

// In your view:
<img src="@Url.Action("GetImage", "MyControllerName", new{fooId = Model.Id})">

// In your controller:
[OutputCache(VaryByParam = "fooId", Duration = 60)]
public ActionResult GetImage(int fooId) {
    // Make sure you check for null as appropriate, re-pull from DB, etc.
    return File((byte[])HttpContext.Cache["image-" + fooId], "image/gif");
}

This has the added benefit (or is it a crutch?) of working in older browsers, where the inline images don't work in IE7 (or IE8 if larger than 32kB).

It could be possible that the compiler translates Set(Integer) to Set(Object) in java byte code. If this is the case, Set(Integer) would be used only at compile phase for syntax checking.

1. You need to open the project file of your program and it should appear on Management panel.

2. Right click on the project file, then select add file. You should add the 3 source code (secrypt.h, secrypt.cpp, and the trial.cpp)

3. Compile and enjoy. Hope, I could help you.

-The tag is Empty and it contains Attribute only. -The tag does not have 'Closing' tag.

So,

<img src='stackoverflow.png'>
<img src='stackoverflow.png' />

both are correct in HTML5 also.

for first 10 rows...

SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT 0,10

for next 10 rows

SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT 10,10

type C:\temp\test.bat>C:\temp\test.log

My solution (similar to KyleLanser's answer) (on a Unix box):

strings dumpfile.dmp | grep SCHEMA_LIST

Extend your main form with this one:

using System.Windows.Forms;

namespace HideWindows
{
    public class HideForm : Form
    {
        public HideForm()
        {
            Opacity = 0;
            ShowInTaskbar = false;
        }

        public new void Show()
        {
            Opacity = 100;
            ShowInTaskbar = true;

            Show(this);
        }
    }
}

For example:

namespace HideWindows
{
    public partial class Form1 : HideForm
    {
        public Form1()
        {
            InitializeComponent();
        }
    }
}

The solution is to add this to the beginning of your .htaccess

<Files wp-login.php>
Order Deny,Allow
Deny from all
Allow from all

It's because many hosts were under attack, using the wordpress from their clients.

After debugging the code, i created my own function just like "blesh"'s answer. So this is what i did

MyModule = angular.module('FIT', [])
.run(function ($rootScope) {
        // Custom $off function to un-register the listener.
        $rootScope.$off = function (name, listener) {
            var namedListeners = this.$$listeners[name];
            if (namedListeners) {
                // Loop through the array of named listeners and remove them from the array.
                for (var i = 0; i < namedListeners.length; i++) {
                    if (namedListeners[i] === listener) {
                        return namedListeners.splice(i, 1);
                    }
                }
            }
        }
});

so by attaching my function to $rootscope now it is available to all my controllers.

and in my code I am doing

$scope.$off("onViewUpdated", callMe);

Thanks

EDIT: The AngularJS way to do this is in @LiviuT's answer! But if you want to de-register the listener in another scope and at the same time want to stay away from creating local variables to keep references of de-registeration function. This is a possible solution.

This code will help you out:-

- (NSString *)getFileName:(UIImageView *)imgView{
    NSString *imgName = [imgView image].accessibilityIdentifier;
    NSLog(@"%@",imgName);
    return imgName;
}

Use this as:-

NSString *currentImageName = [self getFileName:MyIImageView];

To add to the solutions suggesting append, it's useful to know that this is an amortised constant time operation in many cases:

Complexity: Amortized O(1) unless self's storage is shared with another live array; O(count) if self does not wrap a bridged NSArray; otherwise the efficiency is unspecified.

I'm looking for a cons like operator for Swift. It should return a new immutable array with the element tacked on the end, in constant time, without changing the original array. I've not yet found a standard function that does this. I'll try to remember to report back if I find one!

The standard SQL way is to use like:

where @stringVar like '%thisstring%'

That is in a query statement. You can also do this in TSQL:

if @stringVar like '%thisstring%'

this works for me:

git add my_file.txt
git diff --cached my_file.txt
git reset my_file.txt

Last step is optional, it will leave the file in the previous state (untracked)

useful if you are creating a patch too:

  git diff --cached my_file.txt > my_file-patch.patch

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

Pulling data type from information_schema is possible, but not convenient (requires joining several columns with a case statement). Alternatively one can use format_type built-in function to do that, but it works on internal type identifiers that are visible in pg_attribute but not in information_schema. Example

SELECT a.attname as column_name, format_type(a.atttypid, a.atttypmod) AS data_type
FROM pg_attribute a JOIN pg_class b ON a.attrelid = b.relfilenode
WHERE a.attnum > 0 -- hide internal columns
AND NOT a.attisdropped -- hide deleted columns
AND b.oid = 'my_table'::regclass::oid; -- example way to find pg_class entry for a table

Based on https://gis.stackexchange.com/a/97834.

I saw that no one had used the slice method, so here I put my 2 cents here.

df["<col_name>"].str.slice(stop=5)
df["<col_name>"].str.slice(start=6)

This method will create two new columns.

If you are using old version of jQuery(< 1.7) then you can use "bind" instead of "on". This will only work in case you are using old version, since as of jQuery 3.0, "bind" has been deprecated.

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

This will work:

SELECT Replace(Postcode, ' ', '') AS P
FROM Contacts
WHERE Replace(Postcode, ' ', '') LIKE 'NW101%'

SWIFT 4 : Simply create a extension to UIViewController as follows:

extension  UIViewController {        
    func showSuccessAlert(withTitle title: String, andMessage message:String) {
        let alert = UIAlertController(title: title, message: message,
                                  preferredStyle: UIAlertController.Style.alert)
        alert.addAction(UIAlertAction(title: "OK".localized, style:
        UIAlertAction.Style.default, handler: nil))
        self.present(alert, animated: true, completion: nil)
    }
}

Now in your ViewController, directly call above function as if they are provided by UIViewController.

    yourViewController.showSuccessAlert(withTitle: 
      "YourTitle", andMessage: "YourCustomTitle")

You probably have an old version of wget. I suggest installing wget using Chocolatey, the package manager for Windows. This should give you a more recent version (if not the latest).

Run this command after having installed Chocolatey (as Administrator):

I found this really nifty open source ECMAScript compliant JS Engine completely written in C called duktape

Duktape is an embeddable Javascript engine, with a focus on portability and compact footprint.

Good luck!

In the old days, you would use frames to achieve this. There are several reasons why this approach is not so good. See Reece's response to Why are HTML frames bad?. See also Jakob Nielson's Why Frames Suck (Most of the Time).

A somewhat newer approach is to use inline frames. This has pluses and minuses as well: Are iframes considered 'bad practice'?

An even better approach is to use fixed positioning. By placing the navigation content (e.g. the favorites links in your example) in a block element (like a div) then applying position:fixed to that element and setting the left, top and bottom properties like this:

#myNav {
    position: fixed;
    left: 0px;
    top: 0px;
    bottom: 0px;
    width: 200px;
}

... you will achieve a vertical column down the left side of the page that will not move when the user scrolls the page.

The rest of the content on the page will not "feel" the presence of this nav element, so it must take into account the 200px of space it occupies. You can do this by placing the rest for the content in another div and setting margin-left:200px;.

$() is the jQuery constructor function.

this is a reference to the DOM element of invocation.

So basically, in $(this), you are just passing the this in $() as a parameter so that you could call jQuery methods and functions.

When writing queries, this difference should be kept in mind :

DECLARE @A INT = 2

SELECT  @A = TBL.A
FROM    ( SELECT 1 A ) TBL
WHERE   1 = 2

SELECT  @A
/* @A is 2*/

---------------------------------------------------------------

DECLARE @A INT = 2

SET @A = ( 
            SELECT  TBL.A
            FROM    ( SELECT 1 A) TBL
            WHERE   1 = 2
         )

SELECT  @A
/* @A is null*/

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

My code works well using data-dismiss.

<li class="step1">
    <a href="#" class="button-popup" data-dismiss="modal" data-toggle="modal" data-target="#lightbox1">
        <p class="text-label">Step 1</p>
        <p class="text-text">Plan your Regime</p>
    </a>

</li>
<li class="step2">
    <a href="#" class="button-popup" data-dismiss="modal" data-toggle="modal" data-target="#lightbox2">
        <p class="text-label">Step 2</p>
        <p class="text-text">Plan your menu</p>
    </a>
</li>
<li class="step3 active">
    <a href="#" class="button-popup" data-toggle="modal" data-dismiss="modal" data-target="#lightbox3">
        <p class="text-label">Step 3</p>
        <p class="text-text">This Step is Undone.</p>
    </a>

HTML + JQuery: A link that submits a hidden form with POST.

Since I spent a lot of time to understand all these answers, and since all of them have some interesting details, here is the combined version that finally worked for me and which I prefer for its simplicity.

My approach is again to create a hidden form and to submit it by clicking a link somewhere else in the page. It doesn't matter where in the body of the page the form will be placed.

The code for the form:

<form id="myHiddenFormId" action="myAction.php" method="post" style="display: none">
  <input type="hidden" name="myParameterName" value="myParameterValue">
</form>

Description:

The display: none hides the form. You can alternatively put it in a div or another element and set the display: none on the element.

The type="hidden" will create an fild that will not be shown but its data will be transmitted to the action eitherways (see W3C). I understand that this is the simplest input type.

The code for the link:

<a href="" onclick="$('#myHiddenFormId').submit(); return false;" title="My link title">My link text</a>

Description:

The empty href just targets the same page. But it doesn't really matter in this case since the return false will stop the browser from following the link. You may want to change this behavior of course. In my specific case, the action contained a redirection at the end.

The onclick was used to avoid using href="javascript:..." as noted by mplungjan. The $('#myHiddenFormId').submit(); was used to submit the form (instead of defining a function, since the code is very small).

This link will look exactly like any other <a> element. You can actually use any other element instead of the <a> (for example a <span> or an image).

void showfile() throws java.io.IOException  <-----

Your showfile() method throws IOException, so whenever you use it you have to either catch that exception or again thorw it. Something like:

try {
  showfile();
}
catch(IOException e) {
  e.printStackTrace();
}

You should learn about exceptions in Java.

All answers are great. Here is an example use case for multiple add address: The ability to add as many email you want on demand with a web form:

# Script function:
<script>
function emailNext() {
    var nextEmail, inside_where;
    nextEmail = document.createElement('input');
    nextEmail.type = 'text';
    nextEmail.name = 'emails[]';
    nextEmail.className = 'class_for_styling';
    nextEmail.style.display = 'block';
    nextEmail.placeholder  = 'Enter E-mail Here';
    inside_where = document.getElementById('addEmail');
    inside_where.appendChild(nextEmail);
    return false;
}
</script>
# PHP Data Processor:
<?php
// ...
// Add the rest of your $mailer here...
if ($_POST[emails]){
    foreach ($_POST[emails] AS $postEmail){
        if ($postEmail){$mailer->AddAddress($postEmail);}
    }
} 
?>

So what it does basically is to generate a new input text box on every click with the name "emails[]".

The [] added at the end makes it an array when posted.

Then we go through each element of the array with "foreach" on PHP side adding the:

    $mailer->AddAddress($postEmail);

Both keywords are equivalent, but there are a few caveats. One is that declaring a function pointer with using T = int (*)(int, int); is clearer than with typedef int (*T)(int, int);. Second is that template alias form is not possible with typedef. Third is that exposing C API would require typedef in public headers.

After many false starts and dead ends, I'm finally able to deploy website code with just "git push remote" thanks to this article.

The author's post-update script is only one line long and his solution doesn't require .htaccess configuration to hide the Git repo as some others do.

A couple of stumbling blocks if you're deploying this on an Amazon EC2 instance;

1) If you use sudo to create the bare destination repository, you have to change the owner of the repo to ec2-user or the push will fail. (Try "chown ec2-user:ec2-user repo.")

2) The push will fail if you don't pre-configure the location of your amazon-private-key.pem, either in /etc/ssh/ssh_config as an IdentityFile parameter or in ~/.ssh/config using the "[Host] - HostName - IdentityFile - User" layout described here...

...HOWEVER if Host is configured in ~/.ssh/config and different than HostName the Git push will fail. (That's probably a Git bug)

I have resolved this issue.

If your jar files are older than the latest version and the browser has updated to latest version, then download:

• the latest jar files from the selenium website http://www.seleniumhq.org/download/, and
• the latest geckodriver.exe.

You can use a join to do this

SELECT t1.* from myTable t1
LEFT OUTER JOIN myTable t2 on t2.ID=t1.ID AND t2.`Date` > t1.`Date`
WHERE t2.`Date` IS NULL;

Only rows which have the latest date for each ID with have a NULL join to t2.

You can just use the View.setId(integer) for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views you add programmatically.

According to View documentation

The identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.

So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

a.register:active { color: #FFF; text-decoration:none; font-weight:normal; }

{
    [super viewDidLoad];
    tableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];

    // add to superview

// the cell will be returned to the tableView

    static NSString *cellIdentifier = @"HistoryCell";

    // Similar to UITableViewCell, but 
    UITableViewCell *cell = (UITableViewCell *)[theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil)

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }
    cell.descriptionLabel.text = @"Testing";
    return cell;

They way I handle this problem is recursively. For example when reading data from the console:

Java.util.Scanner keyboard = new Java.util.Scanner(System.in);

public int GetMyInt(){
    int ret;
    System.out.print("Give me an Int: ");
    try{
        ret = Integer.parseInt(keyboard.NextLine());

    }
    catch(Exception e){
        System.out.println("\nThere was an error try again.\n");
        ret = GetMyInt();
    }
    return ret;
}

Here's how I did it with facet_grid(yfacet~xfacet) using ggplot2, version 2.2.1:

facet_grid(
    yfacet~xfacet,
    labeller = labeller(
        yfacet = c(`0` = "an y label", `1` = "another y label"),
        xfacet = c(`10` = "an x label", `20` = "another x label")
    )
)

Note that this does not contain a call to as_labeller() -- something that I struggled with for a while.

This approach is inspired by the last example on the help page Coerce to labeller function.

The solution is to define a custom binding inside your Web.Config file and set the security mode to "Transport". Then you just need to use the bindingConfiguration property inside your endpoint definition to point to your custom binding.

Check the reference documentation for FirebaseInstanceIdService:

This class was deprecated.

In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed.

Weirdly enough the JavaDoc for FirebaseMessagingService doesn't mention the onNewToken method yet. It looks like not all updated documentation has been published yet. I've filed an internal issue to get the updates to the reference docs published, and to get the samples in the guide updated too.

In the meantime both the old/deprecated calls, and the new ones should work. If you're having trouble with either, post the code and I'll have a look.

I just found this question and answers as I am trying to do the same thing! I did not want to use some of the other tools mentioned. (Don't want to give my email away, and don't want to pay). I found that Inkscape (v0.91) can do a pretty good job. This tutorial is quick to and easy to understand.

Its as simple as selecting your bitmap in Inkskape and Shift+Alt+B.

                                F(n)
                                /    \
                            F(n-1)   F(n-2)
                            /   \     /      \
                        F(n-2) F(n-3) F(n-3)  F(n-4)
                       /    \
                     F(n-3) F(n-4)

Important point to note is this algorithm is exponential because it does not store the result of previous calculated numbers. eg F(n-3) is called 3 times.

For more details refer algorithm by dasgupta chapter 0.2

I think a more canonical way to do this is via:

command --feature

and

command --no-feature

argparse supports this version nicely:

parser.add_argument('--feature', dest='feature', action='store_true')
parser.add_argument('--no-feature', dest='feature', action='store_false')
parser.set_defaults(feature=True)

Of course, if you really want the --arg <True|False> version, you could pass ast.literal_eval as the "type", or a user defined function ...

def t_or_f(arg):
    ua = str(arg).upper()
    if 'TRUE'.startswith(ua):
       return True
    elif 'FALSE'.startswith(ua):
       return False
    else:
       pass  #error condition maybe?

import re
for i in range(len(myDict.values())):
    for j in range(len(myDict.values()[i])):
         match=re.search(r'Mary', myDict.values()[i][j])
         if match:
                 print match.group() #Mary
                 print myDict.keys()[i] #firstName
                 print myDict.values()[i][j] #Mary-Ann

How about this:

$appended = $a + $b;

There's a couple of ways you can do this. If the onchange listener is a function set via the element.onchange property and you're not bothered about the event object or bubbling/propagation, the easiest method is to just call that function:

element.onchange();

If you need it to simulate the real event in full, or if you set the event via the html attribute or addEventListener/attachEvent, you need to do a bit of feature detection to correctly fire the event:

if ("createEvent" in document) {
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", false, true);
    element.dispatchEvent(evt);
}
else
    element.fireEvent("onchange");

you mentioned "entire line" , so i assumed mystring is the entire line.

if "token" in mystring:
    print(mystring)

however if you want to just get "token qwerty",

>>> mystring="""
...     qwertyuiop
...     asdfghjkl
...
...     zxcvbnm
...     token qwerty
...
...     asdfghjklñ
... """
>>> for item in mystring.split("\n"):
...  if "token" in item:
...     print (item.strip())
...
token qwerty

i think this solution is shorter and simpler than older answers. This is Js Code:

const navbar = document.querySelector('.nav-fixed');
window.onscroll = () => {
    if (window.scrollY > 300) {
        navbar.classList.add('nav-active');
    } else {
        navbar.classList.remove('nav-active');
    }
};

And my css:

header.nav-fixed {
    width: 100%;
    position: fixed;
    transition: 0.3s ease-in-out;
}

.nav-active {
    background-color:#fff;
    box-shadow: 5px -1px 12px -5px grey;
}

You are trying to return an object. Because there is no good way to represent an object as a string, the object's .toString() value is automatically set as "[object Object]".

To select every nth element from any starting position in the vector

nth_element <- function(vector, starting_position, n) { 
  vector[seq(starting_position, length(vector), n)] 
  }

# E.g.
vec <- 1:12

nth_element(vec, 1, 3)
# [1]  1  4  7 10

nth_element(vec, 2, 3)
# [1]  2  5  8 11

You should add "throws IOException" to your main method:

public static void main(String[] args) throws IOException {

You can read a bit more about checked exceptions (which are specific to Java) in JLS.

I've been using this in Python 3, including pattern matching on the filename.

from pathlib import Path

def latest_file(path: Path, pattern: str = "*"):
    files = path.glob(pattern)
    return max(files, key=lambda x: x.stat().st_ctime)

string::c.str() returns a string of type const char * as seen here

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str());

While the above may work, it is undefined behaviour, and unsafe.

Here's a nicer solution using templates:

char * my_argument = const_cast<char*> ( ...c_str() );

And for PHP 5.3, you can use this function, which can be embedded in a class or used in procedural style:

To completely remove the style attribute of the voltaic_holder span, do this:

$("#voltaic_holder").removeAttr("style");

To add an attribute, do this:

$("#voltaic_holder").attr("attribute you want to add", "value you want to assign to attribute");

To remove only the top style, do this:

$("#voltaic_holder").css("top", "");

The "DECOMPRESSION" test fails on CygWin, one of the most potentiaally useful platforms for it, due to the "grep" check for "xz" being case sensitive. The result of the "COMPRESSION:" check is:

COMPRESSION='/dev/stdin: XZ compressed data'

Simply replacing 'grep -q' with 'grep -q -i' everywhere seems to resolve the issue well.

I've done a few updates, particularly adding some comments and using "case" instead of stacked "if" statements, and included that fix below

Personally, to deal with empty responses, I use in my Integration Tests the MockMvcResponse object like this :

MockMvcResponse response = RestAssuredMockMvc.given()
                .webAppContextSetup(webApplicationContext)
                .when()
                .get("/v1/ticket");

    assertThat(response.mockHttpServletResponse().getStatus()).isEqualTo(HttpStatus.NO_CONTENT.value());

and in my controller I return empty response in a specific case like this :

return ResponseEntity.noContent().build();

If you're using webservices, you'll also need the 'allow-http-request-headers-from' element. Here's our default, development, 'allow everything' policy.

<?xml version="1.0" ?>
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="master-only"/>
  <allow-access-from domain="*"/>
  <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

Try this, works in Ruby:

DateTime.now.to_time.utc

Consider a restaurant. The creation of "today's meal" is a factory pattern, because you tell the kitchen "get me today's meal" and the kitchen (factory) decides what object to generate, based on hidden criteria.

The builder appears if you order a custom pizza. In this case, the waiter tells the chef (builder) "I need a pizza; add cheese, onions and bacon to it!" Thus, the builder exposes the attributes the generated object should have, but hides how to set them.

Move doSomething definition outside of its class declaration and after B and also make add accessible to A by public-ing it or friend-ing it.

class B;

class A
{
    void doSomething(B * b);
};

class B
{
public:
    void add() {}
};

void A::doSomething(B * b)
{
    b->add();
}

You should have enough space for array1 array and use something like strcat to contact array1 to array2:

char array1[BIG_ENOUGH];
char array2[X];
/* ......             */
/* check array bounds */
/* ......             */

strcat(array1, array2);

If all you have is a public key from a user in PuTTY-style format, you can convert it to standard openssh format like so:

ssh-keygen -i -f keyfile.pub > newkeyfile.pub

Copy of article

I keep forgetting this so I'm gonna write it here. Non-geeks, just keep walking.

The most common way to make a key on Windows is using Putty/Puttygen. Puttygen provides a neat utility to convert a linux private key to Putty format. However, what isn't addressed is that when you save the public key using puttygen it won't work on a linux server. Windows puts some data in different areas and adds line breaks.

The Solution: When you get to the public key screen in creating your key pair in puttygen, copy the public key and paste it into a text file with the extension .pub. You will save you sysadmin hours of frustration reading posts like this.

HOWEVER, sysadmins, you invariably get the wonky key file that throws no error message in the auth log except, no key found, trying password; even though everyone else's keys are working fine, and you've sent this key back to the user 15 times.

ssh-keygen -i -f keyfile.pub > newkeyfile.pub

Should convert an existing puttygen public key to OpenSSH format.

A solution to this problem could be to apply the filters on controller side :

$scope.tags = $filter('lowercase')($scope.tags);

Don't forget to declare $filter as dependency.

I have faced same problem since I have updated the latest react version. Solved like below.

My code was

async componentDidMount() {
  const { default: Component } = await importComponent();
  Nprogress.done();
  this.setState({
    component: <Component {...this.props} />
  });
}

Changed to

componentWillUnmount() {
  this.mounted = false;
}
async componentDidMount() {
  this.mounted = true;
  const { default: Component } = await importComponent();
  if (this.mounted) {
    this.setState({
      component: <Component {...this.props} />
    });
  }
}

You can use %x or %X or %p; all of them are correct.

• If you use %x, the address is given as lowercase, for example: a3bfbc4
• If you use %X, the address is given as uppercase, for example: A3BFBC4

Both of these are correct.

If you use %x or %X it's considering six positions for the address, and if you use %p it's considering eight positions for the address. For example:

Also instead of adding each file manually, we could do something like:

git add --all

OR

git add -A

This will also remove any files not present or deleted (Tracked files in the current working directory which are now absent).

If you only want to add files which are tracked and have changed, you would want to do

git add -u

What is the difference between git add . & git add --all?

RESOLVED!!!

I have resolved this problem using following steps

1) Remove every file from Git's index.

git rm --cached -r .

2) Rewrite the Git index to pick up all the new line endings.

git reset --hard

Solution was part of steps described on git site https://help.github.com/articles/dealing-with-line-endings/

It happened for me also and the reason was selecting inappropriate combination of tomcat and Dynamic web module version while creating project in eclipse. I selected Tomcat v9.0 along with Dynamic web module version 3.1 and eclipse was not able to resolve the HttpServlet type. When used Tomcat 7.0 along with Dynamic web module version 7.0, eclipse was automatically able to resolve the HttpServlet type.

To check which version of tomcat should be used along with different versions of the Servlet and JSP specifications refer http://tomcat.apache.org/whichversion.html

In PHP 5.5+, you can do

function limit($iterable, $limit) {
    foreach ($iterable as $key => $value) {
        if (!$limit--) break;
        yield $key => $value;
    }
}

foreach (limit($arr, 10) as $key => $value) {
    // do stuff
}

Generators rock.

This the simplest way to assign an async arrow function expression to a named variable:

const foo = async () => {
  // do something
}

_{(Note that this is not strictly equivalent to async function foo() { }. Besides the differences between the function keyword and an arrow expression, the function in this answer is not "hoisted to the top".)}

I suppose, you mean converting a list into a numpy array? Then,

import numpy as np

# b is some list, then ...    
a = np.array(b).reshape(lengthDim0, lengthDim1);

gives you a as an array of list b in the shape given in reshape.

I like visual answers.

As the given tag to this question is CSS, I will provide the way I accomplished it.

1. Create a class in the .css file.

   a.activePage{ color: green; border-bottom: solid; border-width: 3px;}

2. Nav-bar will be like:

   • Home
   • Contact Us
   • About Us

NOTE: If you are already setting the style for all Nav-Bar elements using a class, you can cascade the special-case class we created with a white-space after the generic class in the html-tag.

Example: Here, I was already importing my style from a class called 'navList' I created for all list-items . But the special-case styling-attributes are part of class 'activePage'

.CSS file:

a.navList{text-decoration: none; color: gray;}
a.activePage{ color: green; border-bottom: solid; border-width: 3px;}

.HTML file:

<div id="sub-header">
    <ul>
        <li> <a href="index.php" class= "navList activePage" >Home</a> </li>
        <li> <a href="contact.php" class= "navList">Contact Us</a> </li>
        <li> <a href="about.php" class= "navList">About Us</a> </li>
    </ul>
</div>

Look how I've cascaded one class-name behind other.

Try this:

INSERT INTO test_table (SELECT null,txt FROM test_table)

Every time you run this query, This will insert all the rows again with new ids. values in your table and will increase exponentially.

I used a table with two columns i.e id and txt and id is auto increment.

To normalize the date and eliminate the unwanted offset (tested here : https://jsfiddle.net/7xp1xL5m/ ):

var doo = new Date("2011-09-24");
console.log(  new Date( doo.getTime() + Math.abs(doo.getTimezoneOffset()*60000) )  );
// Output: Sat Sep 24 2011 00:00:00 GMT-0400 (Eastern Daylight Time)

This also accomplishes the same and credit to @tpartee (tested here : https://jsfiddle.net/7xp1xL5m/1/ ):

var doo = new Date("2011-09-24");
console.log( new Date( doo.getTime() - doo.getTimezoneOffset() * -60000 )  );

function String2Stars($string='',$first=0,$last=0,$rep='*'){
  $begin  = substr($string,0,$first);
  $middle = str_repeat($rep,strlen(substr($string,$first,$last)));
  $end    = substr($string,$last);
  $stars  = $begin.$middle.$end;
  return $stars;
}

example

$string = 'abcdefghijklmnopqrstuvwxyz';
echo String2Stars($string,5,-5);   // abcde****************vwxyz

Maybe some change on this topic with QUIC

QUIC (Quick UDP Internet Connections, pronounced quick) is an experimental transport layer network protocol developed by Google and implemented in 2013. QUIC supports a set of multiplexed connections between two endpoints over User Datagram Protocol (UDP), and was designed to provide security protection equivalent to TLS/SSL, along with reduced connection and transport latency, and bandwidth estimation in each direction to avoid congestion. QUIC's main goal is to optimize connection-oriented web applications currently using TCP.

There is a very good article written by: Claudio Bernasconi's TechBlog here: When to use IEnumerable, ICollection, IList and List

Here some basics points about scenarios and functions:

It's just shorthand for $(document).ready(), as in: $(document).ready(function() { YOUR_CODE_HERE });. Sometimes you have to use it because your function is running before the DOM finishes loading.

Everything is explained here: http://docs.jquery.com/Tutorials:Introducing_$(document).ready()

A function name can become a variable name (and thus be passed as an argument) by dropping the parentheses. A variable name can become a function name by adding the parentheses.

In your example, equate the variable rules to one of your functions, leaving off the parentheses and the mention of the argument. Then in your game() function, invoke rules( v ) with the parentheses and the v parameter.

if puzzle == type1:
    rules = Rule1
else:
    rules = Rule2

def Game(listA, listB, rules):
    if rules( v ) == True:
        do...
    else:
        do...

I am researching the same thing and stumbled upon identityserver which implements OAuth and OpenID on top of ASP.NET. It integrates with ASP.NET identity and Membership Reboot with persistence support for Entity Framework.

So, to answer your question, check out their detailed document on how to setup an OAuth and OpenID server.

Ok, I am definitively late to the party but if you are still looking for an optimal solution I would use the following ( for Java 8 )

    Charset inputCharset = Charset.forName("ISO-8859-1");
    Path pathToFile = ....
    try (BufferedReader br = Files.newBufferedReader( pathToFile, inputCharset )) {
        ...
     }

Extrapolating from Rolando's answer above, it is these that are blocking your query:

---TRANSACTION 0 620783788, not started, process no 29956, OS thread id 1196472640
MySQL thread id 5341773, query id 189708353 10.64.89.143 viget

If you need to execute your query and can not wait for the others to run, kill them off using the MySQL thread id:

kill 5341773 <replace with your thread id>

^{(from within mysql, not the shell, obviously)}

You have to find the thread IDs from the:

show engine innodb status\G

command, and figure out which one is the one that is blocking the database.

git-pull - Fetch from and merge with another repository or a local branch
SYNOPSIS

git pull   …
DESCRIPTION

Runs git-fetch with the given parameters, and calls git-merge to merge the 
retrieved head(s) into the current branch. With --rebase, calls git-rebase 
instead of git-merge.

Note that you can use . (current directory) as the <repository> to pull 
from the local repository — this is useful when merging local branches 
into the current branch.

Also note that options meant for git-pull itself and underlying git-merge 
must be given before the options meant for git-fetch.

You would pull if you want the histories merged, you'd fetch if you just 'want the codez' as some person has been tagging some articles around here.

You can use this code to find HyperLink in GridView. Use of e.Row.Cells[0].Controls[0] to find First position of control in GridView.

protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{    
  if(e.Row.RowType == DataControlRowType.DataRow)
    {
        DataRowView v = (DataRowView)e.Row.DataItem;           

        if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0)
        {
            HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink;
            if (link != null)
            {                    
                    link.Text = "Edit";
            }               
        }       

    }
}

Try my way :

robocopy.exe "Desktop\Test folder 1" "Desktop\Test folder 2" /XD "C:\Users\Steve\Desktop\Test folder 2\XXX dont touch" /MIR

Had to put /XD before /MIR while including the full Destination Source directly after /XD.

Isn't it better with a group by? Something like:

SELECT COUNT(*) FROM t1 GROUP BY keywork;

input() by default takes the input in form of strings.

if (0<= vote <=24):

vote takes a string input (suppose 4,5,etc) and becomes uncomparable.

The correct way is: vote = int(input("Enter your message")will convert the input to integer (4 to 4 or 5 to 5 depending on the input)

Use a comma to specify a port number with SQL Server:

mycomputer.test.xxx.com,1234

It's not necessary to specify an instance name when specifying the port.

Lots more examples at http://www.connectionstrings.com/. It's saved me a few times.

If you read the jquery docs, there are numerous reasons for something to not be considered visible/hidden:

They have a CSS display value of none.

They are form elements with type="hidden".

Their width and height are explicitly set to 0.

An ancestor element is hidden, so the element is not shown on the page.

http://api.jquery.com/visible-selector/

Here's a small jsfiddle example with one visible and one hidden element:

--update 2

Please use @Frank's a one line solution:

new Date(SECONDS * 1000).toISOString().substr(11, 8)

It is by far the best solution.

In this case a loop will also do the job (and is usually sufficiently fast).

a <- array(0, dim=dim(X))
for (i in 1:ncol(X)) {a[,i] <- X[,i]}

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

I think you're looking for the ndenumerate.

>>> a =numpy.array([[1,2],[3,4],[5,6]])
>>> for (x,y), value in numpy.ndenumerate(a):
...  print x,y
... 
0 0
0 1
1 0
1 1
2 0
2 1

Regarding the performance. It is a bit slower than a list comprehension.

X = np.zeros((100, 100, 100))

%timeit list([((i,j,k), X[i,j,k]) for i in range(X.shape[0]) for j in range(X.shape[1]) for k in range(X.shape[2])])
1 loop, best of 3: 376 ms per loop

%timeit list(np.ndenumerate(X))
1 loop, best of 3: 570 ms per loop

If you are worried about the performance you could optimise a bit further by looking at the implementation of ndenumerate, which does 2 things, converting to an array and looping. If you know you have an array, you can call the .coords attribute of the flat iterator.

a = X.flat
%timeit list([(a.coords, x) for x in a.flat])
1 loop, best of 3: 305 ms per loop
