I tried all the recommendations listed here. What worked for me was to go to server.properties and add:

port = 9092
advertised.host.name = localhost 

Leave listeners and advertised_listeners commented out.

It is very clear from your exception that it is trying to connect to localhost and not to 10.101.3.229

exception snippet : Could not connect to SMTP host: localhost, port: 25;

1.) Please check if there are any null check which is setting localhost as default value

2.) After restarting, if it is working fine, then it means that only at first-run, the proper value is been taken from Properties and from next run the value is set to default. So keep the property-object as a singleton one and use it all-over your project

In SQL Server, you can use this query:

USE Database_name

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME='Table_Name';

And do not forget to replace Database_name and Table_name with the exact names of your database and table names.

Have you tried setting

li {list-style-type: none;}

According to Need an unordered list without any bullets, you need to add this style to the li elements.

another nice recursive way to generate HTML from a nested JSON object (currently not supporting arrays):

// generate HTML code for an object
var make_table = function(json, css_class='tbl_calss', tabs=1){
    // helper to tabulate the HTML tags. will return '\t\t\t' for num_of_tabs=3
    var tab = function(num_of_tabs){
        var s = '';
        for (var i=0; i<num_of_tabs; i++){
            s += '\t';
        }
        //console.log('tabbing done. tabs=' + tabs)
        return s;
    }
    // recursive function that returns a fixed block of <td>......</td>.
    var generate_td = function(json){ 
        if (!(typeof(json) == 'object')){
            // for primitive data - direct wrap in <td>...</td>
            return tab(tabs) + '<td>'+json+'</td>\n';
        }else{
            // recursive call for objects to open a new sub-table inside the <td>...</td>
            // (object[key] may be also an object)
            var s = tab(++tabs)+'<td>\n';
            s +=        tab(++tabs)+'<table class="'+css_class+'">\n';
            for (var k in json){
                s +=        tab(++tabs)+'<tr>\n';
                s +=          tab(++tabs)+'<td>' + k + '</td>\n';
                s +=                      generate_td(json[k]);
                s +=        tab(--tabs)+'</tr>' + tab(--tabs) + '\n';


            }
            // close the <td>...</td> external block
            s +=        tab(tabs--)+'</table>\n';
            s +=    tab(tabs--)+'</td>\n';
            return s;
        }
    }
    // construct the complete HTML code
    var html_code = '' ;
    html_code += tab(++tabs)+'<table class="'+css_class+'">\n';
    html_code +=   tab(++tabs)+'<tr>\n';
    html_code +=     generate_td(json);
    html_code +=   tab(tabs--)+'</tr>\n';
    html_code += tab(tabs--)+'</table>\n';
    return html_code;
}

What you are looking for is a query with WITH clause, if your dbms supports it. Then

WITH NewScores AS (
    SELECT * 
    FROM Score  
    WHERE InsertedDate >= DATEADD(mm, -3, GETDATE())
)
SELECT 
<and the rest of your query>
;

Note that there is no ; in the first half. HTH.

I would use XMLHTTP request to retrieve page content as much faster. Then it is easy enough to use querySelectorAll to apply a CSS class selector to grab by class name. Then you access the child elements by tag name and index.

Option Explicit
Public Sub GetInfo()
    Dim sResponse As String, html As HTMLDocument, elements As Object, i As Long

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "https://www.hsbc.com/about-hsbc/leadership", False
        .setRequestHeader "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"
        .send
        sResponse = StrConv(.responseBody, vbUnicode)
    End With
    Set html = New HTMLDocument
    With html
        .body.innerHTML = sResponse
        Set elements = .querySelectorAll(".profile-col1")
        For i = 0 To elements.Length - 1
            Debug.Print String(20, Chr$(61))
            Debug.Print elements.item(i).getElementsByTagName("a")(0).innerText
            Debug.Print elements.item(i).getElementsByTagName("p")(0).innerText
            Debug.Print elements.item(i).getElementsByTagName("p")(1).innerText
        Next
    End With
End Sub

The code you have posted here and code on your site both are different. There is a break <br> after second image, so the third image into new line, remove this <br> and it will display correctly.

To Select all

 $('select[name=eventsFilter]').find('option').attr('selected', true);
$('select[name=eventsFilter]').select2();

To UnSellect all

$('select[name=eventsFilter]').find('option').attr('selected', false);
  $('select[name=eventsFilter]').select2("");

You should try this code.

 $("#multiple_Package_Ids_checkboxes").on('change', function (e) { 
        var totAmt = 0;
        $.each($(this).find(":selected"), function (i, item) { 
            totAmt += $(item).data("price");
            });
        $("#PackTotAmt").text(totAmt);
    });

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

In the Hibernate mapping file for the id property, if you use any generator class, for that property you should not set the value explicitly by using a setter method.

If you set the value of the Id property explicitly, it will lead the error above. Check this to avoid this error.

: can also be for block comment (similar to /* */ in C language). For example, if you want to skip a block of code in your script, you can do this:

Is the maximum recommended title length really 50?

I have believed this for years, but as I just noticed the documentation of "git commit" actually states

$ git help commit | grep -C 1 50
      Though not required, it’s a good idea to begin the commit message with
      a single short (less than 50 character) line summarizing the change,
      followed by a blank line and then a more thorough description. The text

$  git version
git version 2.11.0

One could argue that "less then 50" can only mean "no longer than 49".

Be aware that when you do press your <leader> key you have only 1000ms (by default) to enter the command following it.

This is exacerbated because there is no visual feedback (by default) that you have pressed your <leader> key and vim is awaiting the command; and so there is also no visual way to know when this time out has happened.

If you add set showcmd to your vimrc then you will see your <leader> key appear in the bottom right hand corner of vim (to the left of the cursor location) and perhaps more importantly you will see it disappear when the time out happens.

The length of the timeout can also be set in your vimrc, see :help timeoutlen for more information.

JRockit Mission Control is becoming Java Mission Control and will be dedicated exclusively to Hotspot. If you are an Oracle customer, you can download the 5.x versions of Java Mission Control from MOS (My Oracle Support). Java Mission Control will eventually be released together with the Oracle JDK. The reason it is not yet generally available is that there are some serious limitations, especially when using the Flight Recorder. However, if you are only interested in using the JMX console, you should be golden!

I have got this error on open page from Google Cache.

I think, cached page(client) disconnecting on page loading.

You can ignore this error log with try-catch on filter.

This error happens on your side and NOT the other side. If the other side reset the connection, then the exception message should say:

java.net.SocketException reset by peer

The cause is the connection inside HttpClient is stale. Check stale connection for SSL does not fix this error. Solution: dump your client and recreate.

The only workable solution is to restore the .bak file. The contents and the structure of those files are not documented and therefore, there's really no way (other than an awful hack) to get this to work - definitely not worth your time and the effort!

The only tool I'm aware of that can make sense of .bak files without restoring them is Red-Gate SQL Compare Professional (and the accompanying SQL Data Compare) which allow you to compare your database structure against the contents of a .bak file. Red-Gate tools are absolutely marvelous - highly recommended and well worth every penny they cost!

And I just checked their web site - it does seem that you can indeed restore a single table from out of a .bak file with SQL Compare Pro ! :-)

All other answers posted here are only working with public attributes. Here is one solution that works with JavaBeans-like objects using reflection and getters:

function entity2array($entity, $recursionDepth = 2) {
    $result = array();
    $class = new ReflectionClass(get_class($entity));
    foreach ($class->getMethods(ReflectionMethod::IS_PUBLIC) as $method) {
        $methodName = $method->name;
        if (strpos($methodName, "get") === 0 && strlen($methodName) > 3) {
            $propertyName = lcfirst(substr($methodName, 3));
            $value = $method->invoke($entity);

            if (is_object($value)) {
                if ($recursionDepth > 0) {
                    $result[$propertyName] = $this->entity2array($value, $recursionDepth - 1);
                }
                else {
                    $result[$propertyName] = "***";  // Stop recursion
                }
            }
            else {
                $result[$propertyName] = $value;
            }
        }
    }
    return $result;
}

Your action method considers model type asList<string>. But, in your view you are waiting for IEnumerable<Standings.Models.Teams>. You can solve this problem with changing the model in your view to List<string>.

But, the best approach would be to return IEnumerable<Standings.Models.Teams> as a model from your action method. Then you haven't to change model type in your view.

But, in my opinion your models are not correctly implemented. I suggest you to change it as:

public class Team
{
    public int Position { get; set; }
    public string HomeGround {get; set;}
    public string NickName {get; set;}
    public int Founded { get; set; }
    public string Name { get; set; }
}

Then you must change your action method as:

public ActionResult Index()
{
    var model = new List<Team>();

    model.Add(new Team { Name = "MU"});
    model.Add(new Team { Name = "Chelsea"});
    ...

    return View(model);
}

And, your view:

@model IEnumerable<Standings.Models.Team>

@{
     ViewBag.Title = "Standings";
}

@foreach (var item in Model)
{
    <div>
        @item.Name
        <hr />
    </div>
}

When you are storing a DataFrame object into a csv file using the to_csv method, you probably wont be needing to store the preceding indices of each row of the DataFrame object.

You can avoid that by passing a False boolean value to index parameter.

Somewhat like:

df.to_csv(file_name, encoding='utf-8', index=False)

So if your DataFrame object is something like:

  Color  Number
0   red     22
1  blue     10

The csv file will store:

Color,Number
red,22
blue,10

instead of (the case when the default value True was passed)

,Color,Number
0,red,22
1,blue,10

I finally found the problem. The error was not the good one.

Apparently, Ole DB source have a bug that might make it crash and throw that error. I replaced the OLE DB destination with a OLE DB Command with the insert statement in it and it fixed it.

In most of the cases, deleting all the node packages and then installing them again, solve the problem.

But In my case node_modules folder has not write permission.

If you don't wanted to use PIP install atall, then you could do the following:

1) Download the package 2) Use 7 zip for unzipping tar files. ( Use 7 zip again until you see a folder by the name of the package you are looking for. Ex: wordcloud)

3) Locate Python library folder where python is installed and paste the 'WordCloud' folder itself there

4) Success !! Now you can import the library and start using the package.

String[] result = input.split("(?!^)");

What this does is split the input String on all empty Strings that are not preceded by the beginning of the String.

It's pretty pointless to return a const value from a function.

It's difficult to get it to have any effect on your code:

const int foo() {
   return 3;
}

int main() {
   int x = foo();  // copies happily
   x = 4;
}

and:

const int foo() {
   return 3;
}

int main() {
   foo() = 4;  // not valid anyway for built-in types
}

// error: lvalue required as left operand of assignment

Though you can notice if the return type is a user-defined type:

struct T {};

const T foo() {
   return T();
}

int main() {
   foo() = T();
}

// error: passing ‘const T’ as ‘this’ argument of ‘T& T::operator=(const T&)’ discards qualifiers

it's questionable whether this is of any benefit to anyone.

Returning a reference is different, but unless Object is some template parameter, you're not doing that.

I get very nervous when I see people using very large rule sets (e.g., on the order of thousands of rules in a single rule set). This often happens when the rules engine is a singleton sitting in the center of the enterprise in the hope that keeping rules DRY will make them accessible to many apps that require them. I would defy anyone to tell me that a Rete rules engine with that many rules is well-understood. I'm not aware of any tools that can check to ensure that conflicts don't exist.

I think partitioning rules sets to keep them small is a better option. Aspects can be a way to share a common rule set among many objects.

I prefer a simpler, more data driven approach wherever possible.

In case of SSL connections this may be caused by issue in older versions of nginx server that segfault during curl and Safari requests. This bug was fixed around version 1.10 of nginx but there is still a lot of older versions of nginx on the internet.

For nginx admins: adding ssl_session_cache shared:SSL:1m; to http block should solve the problem.

I'm aware that OP was asking for non-SSL case but since this is the top page in goole for "empty reply from server" issue, I'm leaving the SSL answer here as I was one of many that was banging my head against the wall with this issue.

In angular 2 we don't have pre-defined filter and order by as it was with AngularJs, we need to create it for our requirements. It is time killing but we need to do it, (see No FilterPipe or OrderByPipe). In this article we are going to see how we can create filter called pipe in angular 2 and sorting feature called Order By. Let's use a simple dummy json data array for it. Here is the json we will use for our example

First we will see how to use the pipe (filter) by using the search feature:

          { CategoryID: 5,  CategoryName: "Grains/Cereals", Description: "Breads, crackers, pasta, and cereal" },_x000D_
          { CategoryID: 6,  CategoryName: "Beverages", Description: "Beers, and ales" },_x000D_
          { CategoryID: 7,  CategoryName: "Condiments", Description: "Selishes, spreads, and seasonings" },_x000D_
          { CategoryID: 8,  CategoryName: "Confections", Description: "Sweet breads" },_x000D_
          { CategoryID: 9,  CategoryName: "Cheeses",  Description: "Cheese Burger" },_x000D_
          { CategoryID: 10, CategoryName: "Grains/Cereals", Description: "Breads, crackers, pasta, and cereal" }_x000D_
         ];_x000D_
         // this.sort(this.column);_x000D_
      }_x000D_
    }

<div class="col-md-12">_x000D_
  <table class="table table-responsive table-hover">_x000D_
    <tr>_x000D_
      <th >Category ID</th>_x000D_
      <th>Category</th>_x000D_
      <th>Description</th>_x000D_
    </tr>_x000D_
    <tr *ngFor="let item of records">_x000D_
      <td>{{item.CategoryID}}</td>_x000D_
      <td>{{item.CategoryName}}</td>_x000D_
      <td>{{item.Description}}</td>_x000D_
    </tr>_x000D_
  </table>_x000D_
</div>

2.Nothing special in this code just initialize our records variable with a list of categories, two other variables isDesc and column are declared which we will use for sorting latter. At the end added this.sort(this.column); latter we will use, once we will have this method.

Note templateUrl: './category.component.html', which we will create next to show the records in tabluar format.

For this create a HTML page called category.component.html, whith following code:

3.Here we use ngFor to repeat the records and show row by row, try to run it and we can see all records in a table.

Search - Filter Records

Say we want to search the table by category name, for this let's add one text box to type and search

<div class="form-group">_x000D_
  <div class="col-md-6" >_x000D_
    <input type="text" [(ngModel)]="searchText" _x000D_
           class="form-control" placeholder="Search By Category" />_x000D_
  </div>_x000D_
</div>

5.Now we need to create a pipe to search the result by category because filter is not available as it was in angularjs any more.

Create a file category.pipe.ts and add following code in it.

    import { Pipe, PipeTransform } from '@angular/core';_x000D_
    @Pipe({ name: 'category' })_x000D_
    export class CategoryPipe implements PipeTransform {_x000D_
      transform(categories: any, searchText: any): any {_x000D_
        if(searchText == null) return categories;_x000D_
_x000D_
        return categories.filter(function(category){_x000D_
          return category.CategoryName.toLowerCase().indexOf(searchText.toLowerCase()) > -1;_x000D_
        })_x000D_
      }_x000D_
    }

6.Here in transform method we are accepting the list of categories and search text to search/filter record on the list. Import this file into our category.component.ts file, we want to use it here, as follows:

import { CategoryPipe } from './category.pipe';_x000D_
@Component({      _x000D_
  selector: 'app-category',_x000D_
  templateUrl: './category.component.html',_x000D_
  pipes: [CategoryPipe]   // This Line       _x000D_
})

7.Our ngFor loop now need to have our Pipe to filter the records so change it to this.You can see the output in image below

When you create a String, you can think of it as a list of char's, this means that for each character in your String, you need to support all the possible values of char. From the sun docs

char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

If you have a reduced set of characters you want to support you can write a simple compression algorithm, which is analogous to binary->decimal->hex radix converstion. You go from 65,536 (or however many characters your target system supports) to 26 (alphabetical) / 36 (alphanumeric) etc.

I've used this trick a few times, for example encoding timestamps as text (target 36 +, source 10) - just make sure you have plenty of unit tests!

Return an Array Of Objects

private static Object[] f () 
{ 
     double x =1.0;  
     int y= 2 ;
     return new Object[]{Double.valueOf(x),Integer.valueOf(y)};  
}

There is a comment by @afr0 asking how to filter on folders..

There is two ways using the GetDirectoryReference or looping through a containers blobs and checking the type. The code below is in C#

CloudBlobContainer container = blobClient.GetContainerReference("photos");

//Method 1. grab a folder reference directly from the container
CloudBlobDirectory folder = container.GetDirectoryReference("directoryName");

//Method 2. Loop over container and grab folders.
foreach (IListBlobItem item in container.ListBlobs(null, false))
{
    if (item.GetType() == typeof(CloudBlobDirectory))
    {
        // we know this is a sub directory now
        CloudBlobDirectory subFolder = (CloudBlobDirectory)item;

        Console.WriteLine("Directory: {0}", subFolder.Uri);
    }
}

I think you are a little messed up with what you doing. Athlete is an object, athlete has a name, i has a city where he lives. Athlete can dive.

public class Athlete {

private String name;
private String city;

public Athlete (String name, String city){
this.name = name;
this.city = city;
}
--create method dive, (i am not sure what exactly i has to do)
public void dive (){} 
}




public class Main{
public static void main (String [] args){

String name = in.next(); //enter name from keyboad
String city = in.next(); //enter city form keybord

--create a new object athlete and pass paramenters name and city into the object
Athlete a = new Athlete (name, city);

}
}

I had the dependencies as specified @Greg post. I still faced the issue and could be able to resolve it by adding following additional jackson dependency:

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
    <version>2.7.4</version>
</dependency>

What you could do is copy the code from tkinter.py into a file called mytkinter.py, then do this code:

import tkinter, mytkinter
root = tkinter.Tk()
window = mytkinter.Tk()
button = mytkinter.Button(window, text="Search", width = 7,
                               command=cmd)
button2 = tkinter.Button(root, text="Search", width = 7,
                               command=cmdtwo)

And you have two windows which don't collide!

You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

If you're trying to make an installer: Windows Installer does a lot of work for you.

Adding to what you did I changed the functions slightly and removed the &- closing and it worked for me.

    function saveStandardOutputs {
      if [ "$OUTPUTS_REDIRECTED" == "false" ]; then
        exec 3>&1
        exec 4>&2
        trap restoreStandardOutputs EXIT
      else
          echo "[ERROR]: ${FUNCNAME[0]}: Cannot save standard outputs because they have been redirected before"
          exit 1;
      fi
  }

  # Params: $1 => logfile to write to
  function redirectOutputsToLogfile {
      if [ "$OUTPUTS_REDIRECTED" == "false" ]; then
        LOGFILE=$1
        if [ -z "$LOGFILE" ]; then
            echo "[ERROR]: ${FUNCNAME[0]}: logfile empty [$LOGFILE]"
        fi
        if [ ! -f $LOGFILE ]; then
            touch $LOGFILE
        fi
        if [ ! -f $LOGFILE ]; then
            echo "[ERROR]: ${FUNCNAME[0]}: creating logfile [$LOGFILE]"
            exit 1
        fi
        saveStandardOutputs
        exec 1>>${LOGFILE}
        exec 2>&1
        OUTPUTS_REDIRECTED="true"
      else
        echo "[ERROR]: ${FUNCNAME[0]}: Cannot redirect standard outputs because they have been redirected before"
          exit 1;
      fi
  }
  function restoreStandardOutputs {
      if [ "$OUTPUTS_REDIRECTED" == "true" ]; then
      exec 1>&3   #restore stdout
      exec 2>&4   #restore stderr
      OUTPUTS_REDIRECTED="false"
     fi
  }
  LOGFILE_NAME="tmp/one.log"
  OUTPUTS_REDIRECTED="false"

  echo "this goes to stdout"
  redirectOutputsToLogfile $LOGFILE_NAME
  echo "this goes to logfile"
  echo "${LOGFILE_NAME}"
  restoreStandardOutputs 
  echo "After restore this goes to stdout"

Normally you want to perform this check atomically with using the result, so stat() is useless. Instead, open() the file read-only first and use fstat(). If it's a directory, you can then use fdopendir() to read it. Or you can try opening it for writing to begin with, and the open will fail if it's a directory. Some systems (POSIX 2008, Linux) also have an O_DIRECTORY extension to open which makes the call fail if the name is not a directory.

Your method with opendir() is also good if you want a directory, but you should not close it afterwards; you should go ahead and use it.

edit:

Starting from visual studio 2017 Microsoft is no longer offering .ISO images. For the new visual studio 2017 you have to download vs_community.exe from here and create an offline instalation folder:

vs_community.exe --layout c:\vs2017offline

Then, in order to install from that folder you have to first install certificates from \certificates in the download folder and then run the installation.

See: http://predef.sourceforge.net/index.php

This project provides a reasonably comprehensive listing of pre-defined #defines for many operating systems, compilers, language and platform standards, and standard libraries.

in order to center the canvas within the window +"px" should be added to el.style.top and el.style.left.

el.style.top = (viewportHeight - canvasHeight) / 2 +"px";
el.style.left = (viewportWidth - canvasWidth) / 2 +"px";

This is the solution, which is worked for me.

<p:commandButton id="b1" value="Save" process="userGroupSetupForm"
                    actionListener="#{userGroupSetupController.saveData()}" 
                    update="growl userGroupList userGroupSetupForm" />

Here, process="userGroupSetupForm" atrribute is mandatory for Ajax call. actionListener is calling a method from @ViewScope Bean. Also updating growl message, Datatable: userGroupList and Form: userGroupSetupForm.

 var myEle = document.getElementById("myElement");
    if(myEle){
        var myEleValue= myEle.value;
    }

the return of getElementById is null if an element is not actually present inside the dom, so your if statement will fail, because null is considered a false value

CSS does not have an onlclick event handler. You have to use Javascript.

See more info here on CSS Pseudo-classes: http://www.w3schools.com/css/css_pseudo_classes.asp

a:visited {color:#00FF00;} /* visited link - user has already been to this page */
a:hover {color:#FF00FF;}   /* mouse over link - user is hovering over the link with the mouse or has selected it with the keyboard */
a:active {color:#0000FF;}  /* selected link - the user has clicked the link and the browser is loading the new page */

You'd need to put it in a class somewhere, and the usage would be ClassName.NUMBER

PHP 7.1.0 has introduced the iterable pseudo-type and the is_iterable() function, which is specially designed for such a purpose:

This […] proposes a new iterable pseudo-type. This type is analogous to callable, accepting multiple types instead of one single type.

iterable accepts any array or object implementing Traversable. Both of these types are iterable using foreach and can be used with yield from within a generator.

function foo(iterable $iterable) {
    foreach ($iterable as $value) {
        // ...
    }
}

This […] also adds a function is_iterable() that returns a boolean: true if a value is iterable and will be accepted by the iterable pseudo-type, false for other values.

var_dump(is_iterable([1, 2, 3])); // bool(true)
var_dump(is_iterable(new ArrayIterator([1, 2, 3]))); // bool(true)
var_dump(is_iterable((function () { yield 1; })())); // bool(true)
var_dump(is_iterable(1)); // bool(false)
var_dump(is_iterable(new stdClass())); // bool(false)

You can also use the function is_array($var) to check if the passed variable is an array:

<?php
    var_dump( is_array(array()) ); // true
    var_dump( is_array(array(1, 2, 3)) ); // true
    var_dump( is_array($_SERVER) ); // true
?>

Read more in How to check if a variable is an array in PHP?

I think what you want ist

return value.toString();

and use the return value to display.

value.floatValue();

will always return 625.3 because its mainly used to calculate something.

The new networking feature allows you to connect to containers by their name, so if you create a new network, any container connected to that network can reach other containers by their name. Example:

1) Create new network

$ docker network create <network-name>       

2) Connect containers to network

$ docker run --net=<network-name> ...

or

$ docker network connect <network-name> <container-name>

3) Ping container by name

docker exec -ti <container-name-A> ping <container-name-B> 

64 bytes from c1 (172.18.0.4): icmp_seq=1 ttl=64 time=0.137 ms
64 bytes from c1 (172.18.0.4): icmp_seq=2 ttl=64 time=0.073 ms
64 bytes from c1 (172.18.0.4): icmp_seq=3 ttl=64 time=0.074 ms
64 bytes from c1 (172.18.0.4): icmp_seq=4 ttl=64 time=0.074 ms

See this section of the documentation;

Note: Unlike legacy links the new networking will not create environment variables, nor share environment variables with other containers.

This feature currently doesn't support aliases

You ask two questions; your title says "Displaying a vector of strings", but you're not actually doing that, you actually build a single string composed of all the strings and output that.

Your question body asks "Why doesn't this work".

It doesn't work because your for loop is constrained by "userString.size()" which is 0, and you test your loop variable for being "userString.size() - 1". The condition of a for() loop is tested before permitting execution of the first iteration.

int n = 1;
for (int i = 1; i < n; ++i) {
    std::cout << i << endl;
}

will print exactly nothing.

So your loop executes exactly no iterations, leaving userString and sentence empty.

Lastly, your code has absolutely zero reason to use a vector. The fact that you used "decltype(userString.size())" instead of "size_t" or "auto", while claiming to be a rookie, suggests you're either reading a book from back to front or you are setting yourself up to fail a class.

So to answer your question at the end of your post: It doesn't work because you didn't step through it with a debugger and inspect the values as it went. While I say it tongue-in-cheek, I'm going to leave it out there.

I would go with Lev, but it's worth pointing out that if you end up with more complex searches that using re.finditer may be worth bearing in mind (but re's often cause more trouble than worth - but sometimes handy to know)

test = "ooottat"
[ (i.start(), i.end()) for i in re.finditer('o', test)]
# [(0, 1), (1, 2), (2, 3)]

[ (i.start(), i.end()) for i in re.finditer('o+', test)]
# [(0, 3)]

Lookarounds can be nested.

So this regex matches "drupal-6.14/" that is not followed by "sites" that is not followed by "/all" or "/default".

Confusing? Using different words, we can say it matches "drupal-6.14/" that is not followed by "sites" unless that is further followed by "/all" or "/default"

Here's another method, which happens to use no correlated subqueries or GROUP BY. I'm not expert in PostgreSQL performance tuning, so I suggest you try both this and the solutions given by other folks to see which works better for you.

SELECT l1.*
FROM lives l1 LEFT OUTER JOIN lives l2
  ON (l1.usr_id = l2.usr_id AND (l1.time_stamp < l2.time_stamp 
   OR (l1.time_stamp = l2.time_stamp AND l1.trans_id < l2.trans_id)))
WHERE l2.usr_id IS NULL
ORDER BY l1.usr_id;

I am assuming that trans_id is unique at least over any given value of time_stamp.

To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:

rpm -qa | grep mariadb

then remove the mariadb packages using (changing to your versions):

rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"

Delete left over files and folders (which also removes any databases):

rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql

Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.

There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL

Getting the address of an arbitrary object in .NET is not possible, but can be done if you change the source code and use mono. See instructions here: Get Memory Address of .NET Object (C#)

Don't use locals in Rails 4.2+

In Rails 4.2 I had to remove the locals part and just use size: 30 instead. Otherwise, it wouldn't pass the local variable correctly.

For example, use this:

<%= render @users, size: 30 %>

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

To do it without using a JavaScript library such as jQuery, you'd do it like this:

var span = document.getElementById("myspan"),
    text = document.createTextNode(''+intValue);
span.innerHTML = ''; // clear existing
span.appendChild(text);

If you do want to use jQuery, it's just this:

$("#myspan").text(''+intValue);

I actually like the previous answer (don't use the SP), but if you're tied to the SP itself for some reason, you could use it to populate a temp table, and then join on the temp table. Note that you're going to cost yourself some additional overhead there, but it's the only way I can think of to use the actual stored proc.

Again, you may be better off in-lining the query from the SP into the original query.

This is a simple copy, just like you would do with memcpy() (indeed, some compilers actually produce a call to memcpy() for that code). There is no "string" in C, only pointers to a bunch a chars. If your source structure contains such a pointer, then the pointer gets copied, not the chars themselves.

I had this issue today on a repo.

It wasn't the +refs/heads/*:refs/remotes/origin/* issue as per top solution.

Symptom was simply that git fetch origin or git fetch just didn't appear to do anything, although there were remote branches to fetch.

After trying lots of things, I removed the origin remote, and recreated it. That seems to have fixed it. Don't know why.

remove with: git remote rm origin

and recreate with: git remote add origin <git uri>

You should install the graphviz package in your system (not just the python package). On Ubuntu you should try:

sudo apt-get install graphviz

You haven't specified what kind of html element you are trying to do an absolute xpath search on. In your case, it's the input element.

Try this:

element = findElement(By.xpath("//input[@class='t-TextBox' and @type='email' and @test-    
id='test-username']");

In linux terminal try this:

• sudo service postgresql start : to start the server
• sudo service postgresql stop : to stop thee server
• sudo service postgresql status : to check server status

The answer posted to this question as an example taken from Microsoft's MSDN is nice however it doesn't directly demonstrate where the error comes from if it doesn't come from the TRY Block. I prefer this example with a very minor update to the RAISERROR Message within the CATCH Block stating that the error is from the CATCH Block. I demonstrate this in the gif as well.

BEGIN TRY
    /* RAISERROR with severity 11-19 will cause execution
     |  to jump to the CATCH block.
    */
    RAISERROR ('Error raised in TRY block.', -- Message text.
               5, -- Severity. /* Severity Levels Less Than 11 do not jump to the CATCH block */
               1 -- State.
               );
END TRY

BEGIN CATCH
    DECLARE @ErrorMessage  NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState    INT;

    SELECT 
        @ErrorMessage  = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState    = ERROR_STATE();

    /* Use RAISERROR inside the CATCH block to return error
     | information about the original error that caused
     | execution to jump to the CATCH block
    */
    RAISERROR ('Caught Error in Catch', --@ErrorMessage, /* Message text */
               @ErrorSeverity,                           /* Severity     */
               @ErrorState                               /* State        */
               );
END CATCH;

You can use parents method with specified .class selector and check if any of them matches it:

if ($elem.parents('.left').length != 0) {
    //someone has this class
}

I had the same problem and solved with '%' operator:

select 12.54 % 1;

• Note: I do know that this doesn't answer this specific question. But it is a question that people come to via a search engine. So i'm posting this here believing it will help those users.

You should keep in mind that if you are accessing class-wide enum from another function even if it is a friend, you need to provide values with a class name:

class PlayingCard
{
private:
  enum Suit { CLUBS, DIAMONDS, HEARTS, SPADES };
  int rank;
  Suit suit;
  friend std::ostream& operator<< (std::ostream& os, const PlayingCard &pc);
};

std::ostream& operator<< (std::ostream& os, const PlayingCard &pc)
{
  // output the rank ...

  switch(pc.suit)
  {
    case PlayingCard::HEARTS:
      os << 'h';
      break;
    case PlayingCard::DIAMONDS:
      os << 'd';
      break;
    case PlayingCard::CLUBS:
      os << 'c';
      break;
    case PlayingCard::SPADES:
      os << 's';
      break;
  }
  return os;
}

Note how it is PlayingCard::HEARTS and not just HEARTS.

Or you can try CGI.unescapeHTML method.

CGI.unescapeHTML "<p>This is a Paragraph.</p>"

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

Building on Ravinders solution, this code stops the form being submitted. It might be wise to check the extension at the server-side too. So you don't get hackers uploading anything they want.

<script>
var valid = false;

function validate_fileupload(input_element)
{
    var el = document.getElementById("feedback");
    var fileName = input_element.value;
    var allowed_extensions = new Array("jpg","png","gif");
    var file_extension = fileName.split('.').pop(); 
    for(var i = 0; i < allowed_extensions.length; i++)
    {
        if(allowed_extensions[i]==file_extension)
        {
            valid = true; // valid file extension
            el.innerHTML = "";
            return;
        }
    }
    el.innerHTML="Invalid file";
    valid = false;
}

function valid_form()
{
    return valid;
}
</script>

<div id="feedback" style="color: red;"></div>
<form method="post" action="/image" enctype="multipart/form-data">
  <input type="file" name="fileName" accept=".jpg,.png,.bmp" onchange="validate_fileupload(this);"/>
  <input id="uploadsubmit" type="submit" value="UPLOAD IMAGE" onclick="return valid_form();"/>
</form>

To answer you first question:
Yes, it means that 1 byte allocates for 1 character. Look at this example

SQL> conn / as sysdba
Connected.
SQL> create table test (id number(10), v_char varchar2(10));

Table created.

SQL> insert into test values(11111111111,'darshan');
insert into test values(11111111111,'darshan')
*
ERROR at line 1:
ORA-01438: value larger than specified precision allows for this column


SQL> insert into test values(11111,'darshandarsh');
insert into test values(11111,'darshandarsh')
*
ERROR at line 1:
ORA-12899: value too large for column "SYS"."TEST"."V_CHAR" (actual: 12,
maximum: 10)


SQL> insert into test values(111,'Darshan');

1 row created.

SQL> 

And to answer your next one: The difference between varchar2 and varchar :

1. VARCHAR can store up to 2000 bytes of characters while VARCHAR2 can store up to 4000 bytes of characters.
2. If we declare datatype as VARCHAR then it will occupy space for NULL values, In case of VARCHAR2 datatype it will not occupy any space.

It is also possible to use this:

var user_name = document.forms[0].elements[0];
var user_email = document.forms[0].elements[1];
var user_message = document.forms[0].elements[2];

All the elements of forms are stored in an array by Javascript. This takes the elements from the first form and stores each value into a unique variable.

$('form').submit( function(e){

     e.preventDefault();

     //later you decide you want to submit
     $(this).trigger('submit');     or     $(this).trigger('anyEvent');

In a query you can just do something like:

SELECT ColumnA * ColumnB FROM table

or

SELECT ColumnA - ColumnB FROM table

You can also create computed columns in your table where you can permanently use your formula.

Even simpler:

=indirect(address(row(), column() - 1))

OFFSET returns a reference relative to the current reference, so if indirect returns the correct reference, you don't need it.

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_
</div>

I tried very hard on this question, and I find the best answer here: (from how to loop 7 times in the django templates)

You can even access the idx!

views.py:

context['loop_times'] = range(1, 8)

html:

{% for i in loop_times %}
        <option value={{ i }}>{{ i }}</option>
{% endfor %}

Some version working

<div class="hidden-xs">Only Mobile hidden</div>
<div class="visible-xs">Only Mobile visible</div>

This method will work for xamp/wamp/lamp

1. 1st go to your server directory, for example, C:\xamp
2. 2nd go to apache/conf/extra and open httpd-vhosts.conf
3. 3rd add following code to this file

 <VirtualHost myWebsite.local>
        DocumentRoot "C:/wamp/www/php-bugs/"
        ServerName php-bugs.local
        ServerAlias php-bugs.local
        <Directory "C:/wamp/www/php-bugs/">
            Order allow,deny
            Allow from all
        </Directory>
    </VirtualHost>

For DocumentRoot and Directory add your local directory For ServerName and ServerAlias give your server a name

4. Finally go to C:/Windows/System32/drivers/etc and open hosts file
   add 127.0.0.1 php-bugs.local and nothing else

5. For the finishing touch restart your server

   For Multile local domain add another section of code into httpd-vhosts.conf

 <VirtualHost myWebsite.local>
        DocumentRoot "C:/wamp/www/php-bugs2/"
        ServerName php-bugs.local2
        ServerAlias php-bugs.local2
        <Directory "C:/wamp/www/php-bugs2/">
            Order allow,deny
            Allow from all
        </Directory>
    </VirtualHost>

and add your host into host file 127.0.0.1 php-bugs.local2

The pixel width and height of your page will depend on orientation as well as the meta viewport tag, if specified. Here are the results of running jquery's $(window).width() and $(window).height() on iPad 1 browser.

When page has no meta viewport tag:

• Portrait: 980x1208
• Landscape: 980x661

When page has either of these two meta tags:

<meta name="viewport" content="initial-scale=1,user-scalable=no,maximum-scale=1,width=device-width">

From here:

http://www.christianengvall.se/undo-pushed-merge-git/

git revert -m 1 <merge commit hash>

Git revert adds a new commit that rolls back the specified commit.

Using -m 1 tells it that this is a merge and we want to roll back to the parent commit on the master branch. You would use -m 2 to specify the develop branch.

BtnAdd.CssClass = "BtnCss";

BtnCss should be present in your Css File.

(reference of that Css File name should be added to the aspx if needed)

As Bhavik Shah says, you can do it in JAVA_OPTS, but the recommended way (as per catalina.sh) is to use CATALINA_OPTS:

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc.

#   JAVA_OPTS       (Optional) Java runtime options used when any command
#                   is executed.
#                   Include here and not in CATALINA_OPTS all options, that
#                   should be used by Tomcat and also by the stop process,
#                   the version command etc.
#                   Most options should go into CATALINA_OPTS.

Can't tell you how many times this has caught. me.

Guid myGuid = Guid.NewGuid(); 

DateTime start = new DateTime(2013, 10, 20, 5, 0, 0, Locale);
DateTime end = new DateTime(2013, 10, 21, 13, 0, 0, Locale);
Days.daysBetween(start.toLocalDate(), end.toLocalDate()).getDays()

it returns how many days between given two dates, where DateTime is from joda library

You can use ng-init as shown below

<div class="TotalForm">
  <label>B/W Print Total</label>
  <div ng-init="{{BWCount=(oMachineAccounts|sumByKey:'BWCOUNT')}}">{{BWCount}}</div>
</div>
<div class="TotalForm">
  <label>Color Print Total</label>
  <div ng-init="{{ColorCount=(oMachineAccounts|sumByKey:'COLORCOUNT')}}">{{ColorCount}}</div>
</div>

and then use the local scope variable in other sections:

<div>Total: BW: {{BWCount}}</div>
<div>Total: COLOR: {{ColorCount}}</div>

Type on terminal:

 composer global require "laravel/installer"

When composer finish, type:

vi ~/.bashrc

Paste and save:

export PATH="~/.config/composer/vendor/bin:$PATH"

Type on terminal:

source ~/.bashrc

Open another terminal window and type: laravel

I have the same problem like you and luckily I have read the solution from this link: http://access-excel.tips/value-before-worksheet-change/

Dim oldValue As Variant
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    oldValue = Target.Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
    'do something with oldValue...
End Sub

Note: you must place oldValue variable as a global variable so all subclasses can use it.

You also might notice a little lag because 0deg and 360deg are the same spot, so it is going from spot 1 in a circle back to spot 1. It is really insignificant, but to fix it, all you have to do is change 360deg to 359deg

my jsfiddle illustrates your animation:

#myImg {
    -webkit-animation: rotation 2s infinite linear;
}

@-webkit-keyframes rotation {
    from {-webkit-transform: rotate(0deg);}
    to   {-webkit-transform: rotate(359deg);}
}

Also what might be more resemblant of the apple loading icon would be an animation that transitions the opacity/color of the stripes of gray instead of rotating the icon.

This should work for all elements regardless of when they are generated.

if($('some_element').length == 0) {
}

write your code in the ajax callback functions and it should work fine.

We can use the core java stuff alone to read the CVS file column by column. Here is the sample code I have wrote for my requirement. I believe that it will help for some one.

 BufferedReader br = new BufferedReader(new FileReader(csvFile));
    String line = EMPTY;
    int lineNumber = 0;

    int productURIIndex = -1;
    int marketURIIndex = -1;
    int ingredientURIIndex = -1;
    int companyURIIndex = -1;

    // read comma separated file line by line
    while ((line = br.readLine()) != null) {
        lineNumber++;
        // use comma as line separator
        String[] splitStr = line.split(COMMA);
        int splittedStringLen = splitStr.length;

        // get the product title and uri column index by reading csv header
        // line
        if (lineNumber == 1) {
            for (int i = 0; i < splittedStringLen; i++) {
                if (splitStr[i].equals(PRODUCTURI_TITLE)) {
                    productURIIndex = i;
                    System.out.println("product_uri index:" + productURIIndex);
                }

                if (splitStr[i].equals(MARKETURI_TITLE)) {
                    marketURIIndex = i;
                    System.out.println("marketURIIndex:" + marketURIIndex);
                }

                if (splitStr[i].equals(COMPANYURI_TITLE)) {
                    companyURIIndex = i;
                    System.out.println("companyURIIndex:" + companyURIIndex);
                }

                if (splitStr[i].equals(INGREDIENTURI_TITLE)) {
                    ingredientURIIndex = i;
                    System.out.println("ingredientURIIndex:" + ingredientURIIndex);
                }
            }
        } else {
            if (splitStr != null) {
                String conditionString = EMPTY;
                // avoiding arrayindexoutboundexception when the line
                // contains only ,,,,,,,,,,,,,
                for (String s : splitStr) {
                    conditionString = s;
                }
                if (!conditionString.equals(EMPTY)) {
                    if (productURIIndex != -1) {
                        productCVSUriList.add(splitStr[productURIIndex]);
                    }
                    if (companyURIIndex != -1) {
                        companyCVSUriList.add(splitStr[companyURIIndex]);
                    }
                    if (marketURIIndex != -1) {
                        marketCVSUriList.add(splitStr[marketURIIndex]);
                    }
                    if (ingredientURIIndex != -1) {
                        ingredientCVSUriList.add(splitStr[ingredientURIIndex]);
                    }
                }
            }
        }

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

Check out javax.imageio, especially ImageReader and ImageWriter as an abstraction for reading and writing image files.

BufferedImage.getRGB(int x, int y) than allows you to get RGB values on the given pixel, which can be chunked into bytes.

Note: I think you don't want to read the raw bytes, because then you have to deal with all the compression/decompression.

if you get "unexpected Character" error you should check if there is a BOM (Byte Order Marker saved into your utf-8 json. You can either remove the first character or save if without BOM.

I think you want to make objects from array and combine it with an old object (BODY.recipients.values), if it's then you may do it using $.extent (because you are using jQuery/tagged) method after prepare the object from array

var BODY = {
    "recipients": {
        "values": []
    },
    "subject": 'TitleOfSubject',
    "body": 'This is the message body.'
}

var values = [],
names = ['sheikh', 'muhammed', 'Answer', 'Uddin', 'Heera']; // for testing
for (var ln = 0; ln < names.length; ln++) {
    var item1 = {
        "person": { "_path": "/people/"+names[ln] }
    };
    values.push(item1);
}

// Now merge with BODY
$.extend(BODY.recipients.values, values);

DEMO.

I faced the very same error when I was trying to connect to my SQL Server 2014 instance using sa user using SQL Server Management Studio (SSMS). I was facing this error even when security settings for sa user was all good and SQL authentication mode was enabled on the SQL Server instance.

Finally, the issue turned out to be that Named Pipes protocol was disabled. Here is how you can enable it:

Open SQL Server Configuration Manager application from start menu. Now, enable Named Pipes protocol for both Client Protocols and Protocols for <SQL Server Instance Name> nodes as shown in the snapshot below:

Note: Make sure you restart the SQL Server instance after making changes.

P.S. I'm not very sure but there is a possibility that the Named Pipes enabling was required under only one of the two nodes that I've advised. So you can try it one after the other to reach to a more precise solution.

The result of a modulo division is the remainder of an integer division of the given numbers.

That means:

27 / 16 = 1, remainder 11
=> 27 mod 16 = 11

Other examples:

30 / 3 = 10, remainder 0
=> 30 mod 3 = 0

35 / 3 = 11, remainder 2
=> 35 mod 3 = 2

The easiest method is to use the toArray(IntFunction<A[]> generator) method with an array constructor reference. This is suggested in the API documentation for the method.

String[] stringArray = stringStream.toArray(String[]::new);

What it does is find a method that takes in an integer (the size) as argument, and returns a String[], which is exactly what (one of the overloads of) new String[] does.

You could also write your own IntFunction:

Stream<String> stringStream = ...;
String[] stringArray = stringStream.toArray(size -> new String[size]);

The purpose of the IntFunction<A[]> generator is to convert an integer, the size of the array, to a new array.

Example code:

Stream<String> stringStream = Stream.of("a", "b", "c");
String[] stringArray = stringStream.toArray(size -> new String[size]);
Arrays.stream(stringArray).forEach(System.out::println);

Prints:

a
b
c

For IntelliJ IDEA 2017.2 I did the following to fix this issue: Go to your project structure Now go to SDKs under platform settings and click the green add button. Add your JDK path. In my case it was this path C:\Program Files\Java\jdk1.8.0_144 Now Just go Project under Project settings and select the project SDK.

checked :

public Constructor(Class<E> c, int length) {

    elements = (E[]) Array.newInstance(c, length);
}

or unchecked :

public Constructor(int s) {
    elements = new Object[s];
}

By the way it is written, clean rule is invoked only if it is explicitly called:

make clean

I think it is better, than make clean every time. If you want to do this by your way, try this:

CXX = g++ -O2 -Wall

all: clean code1 code2

code1: code1.cc utilities.cc
   $(CXX) $^ -o $@

code2: code2.cc utilities.cc
   $(CXX) $^ -o $@

clean: 
    rm ...
    echo Clean done

As I understand it is because of rxjs last update. They have changed some operators and syntax. Thereafter we should import rx operators like this

import { map } from "rxjs/operators";

instead of this

import 'rxjs/add/operator/map';

And we need to add pipe around all operators like this

this.myObservable().pipe(map(data => {}))

Source is here

Instead of using ->bindParam() you can pass the data only at the time of ->execute():

$data = [   ':item_name' => $_POST['item_name'],   ':item_type' => $_POST['item_type'],   ':item_price' => $_POST['item_price'],   ':item_description' => $_POST['item_description'],   ':image_location' => 'images/'.$_FILES['file']['name'],   ':status' => 0,   ':id' => 0, ];  $stmt->execute($data); 

In this way you would know exactly what values are going to be sent.

I would follow official projects like tar as an example. In my opinion help msg. needs to be simple and descriptive as possible. Examples of use are good too. There is no real need for "standard help".

You can use crypto-js.

To use crypto-js, you need to load core.js then md5.js .

A list of URLs are here https://cdnjs.com/libraries/crypto-js

cryptojs is also available in zip form here https://code.google.com/archive/p/crypto-js/downloads

There is an answer from answerer 'amal' in 2013, that is similar to this but a)his link to md5.js no longer works b)he didn't load core.js beforehand, which is necessary.

If the string contains UTF-8 characters outside of the ASCII range, then boost::algorithm::to_lower will not convert those. Better use boost::locale::to_lower when UTF-8 is involved. See http://www.boost.org/doc/libs/1_51_0/libs/locale/doc/html/conversions.html

Adding to @Martin's answer...

If anyone planning to keep an application level constant file, you can group the constant based on their type or nature

struct Constants {
    struct MixpanelConstants {
        static let activeScreen = "Active Screen";
    }
    struct CrashlyticsConstants {
        static let userType = "User Type";
    }
}

Call : Constants.MixpanelConstants.activeScreen

UPDATE 5/5/2019 (kinda off topic but ???)

After reading some code guidelines & from personal experiences it seems structs are not the best approach for storing global constants for a couple of reasons. Especially the above code doesn't prevent initialization of the struct. We can achieve it by adding some boilerplate code but there is a better approach

ENUMS

The same can be achieved using an enum with a more secure & clear representation

enum Constants {
    enum MixpanelConstants: String {
        case activeScreen = "Active Screen";
    }
    enum CrashlyticsConstants: String {
        case userType = "User Type";
    }
}

print(Constants.MixpanelConstants.activeScreen.rawValue)

In C++11, you can do this with standard library facilities:

#include <chrono>
#include <thread>

std::this_thread::sleep_for(std::chrono::milliseconds(x));

Clear and readable, no more need to guess at what units the sleep() function takes.

Use the following command outside the WEB-INF folder. This should create your war file and is the quickest method I know.

Finally, you only need to save it in a .VBS file (VBScript) and run it.

I have the same problem on my virtual environment after upgrade python installation from 3.6 to 3.7 but only on vent globally pip work fine, to solve it I deactivate and delete my virtual environment after recreate again and now is fine, on venv:

deactivate
rm -rvf venv 

and after recreate the virtual environment. I use mac OS 10.11, and python 3

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

For anyone checking this question recently, Rails 5.2+ now has ActiveStorage by default & I highly recommend checking it out.

Since it is part of the core Rails 5.2+ now, it is very well integrated & has excellent capabilities out of the box (still all other well-known gems like Carrierwave, Shrine, paperclip,... are great but this one offers very good features that we can consider for any new Rails project)

Paperclip team deprecated the gem in favor of the Rails ActiveStorage.

Here is the github page for the ActiveStorage & plenty of resources are available everywhere

Also I found this video to be very helpful to understand the features of Activestorage

If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.

    private File createFile(String path, String fileName) throws IOException {
       ClassLoader classLoader = getClass().getClassLoader();
       File file = new File(classLoader.getResource(".").getFile() + path + fileName);

       // Lets create the directory
       try {
          file.getParentFile().mkdir();
       } catch (Exception err){
           System.out.println("ERROR (Directory Create)" + err.getMessage());
       }

       // Lets create the file if we have credential
       try {
           file.createNewFile();
       } catch (Exception err){
           System.out.println("ERROR (File Create)" + err.getMessage());
       }
       return  file;
   }

refer to the basic.

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]')";
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

When you want to access an element, you have to first dereference your pointer, and then index the element you want (which is also dereferncing). i.e. you need to do:

printf("\nvalue:%c", (*ptr)[0]); , which is the same as *((*ptr)+0)

Note that working with pointer to arrays are not very common in C. instead, one just use a pointer to the first element in an array, and either deal with the length as a separate element, or place a senitel value at the end of the array, so one can learn when the array ends, e.g.

char arr[5] = {'a','b','c','d','e',0}; 
char *ptr = arr; //same as char *ptr = &arr[0]

printf("\nvalue:%c", ptr[0]);

You can extend multiple Interfaces but you cannot extend multiple classes.

The reason that it is not possible in Java to extending multiple classes, is the bad experience from C++ where this is possible.

The alternative for multipe inheritance is that a class can implement multiple interfaces (or an Interface can extend multiple Interfaces)

Question 1:

   vectorOfGamers.push_back(Player)

This is problematic because you cannot directly push a class name into a vector. You can either push an object of class into the vector or push reference or pointer to class type into the vector. For example:

vectorOfGamers.push_back(Player(name, id)) 
  //^^assuming name and id are parameters to the vector, call Player constructor
  //^^In other words, push `instance`  of Player class into vector

Question 2:

These 3 classes derives from Gamer. Can I create vector to hold objects of Dealer, Bot and Player at the same time? How do I do that?

Yes you can. You can create a vector of pointers that points to the base class Gamer. A good choice is to use a vector of smart_pointer, therefore, you do not need to manage pointer memory by yourself. Since the other three classes are derived from Gamer, based on polymorphism, you can assign derived class objects to base class pointers. You may find more information from this post: std::vector of objects / pointers / smart pointers to pass objects (buss error: 10)?

Use

Console.WriteLine(String.Format("  {0:G17}", i));

That will give you all the 17 digits it have. By default, a Double value contains 15 decimal digits of precision, although a maximum of 17 digits is maintained internally. {0:R} will not always give you 17 digits, it will give 15 if the number can be represented with that precision.

which returns 15 digits if the number can be represented with that precision or 17 digits if the number can only be represented with maximum precision. There isn't any thing you can to do to make the the double return more digits that is the way it's implemented. If you don't like it do a new double class yourself...

.NET's double cant store any more digits than 17 so you cant see 6.89999999999999946709 in the debugger you would see 6.8999999999999995. Please provide an image to prove us wrong.

While many of you have touched upon major adv./dis of linked list vs array, most of the comparisons are how one is better/ worse than the other.Eg. you can do random access in array but not possible in linked list and others. However, this is assuming link lists and array are going to be applied in a similar application. However a correct answer should be how link list would be preferred over array and vice-versa in a particular application deployment. Suppose you want to implement a dictionary application, what would you use ? Array : mmm it would allow easy retrieval through binary search and other search algo .. but lets think how link list can be better..Say you want to search "Blob" in dictionary. Would it make sense to have a link list of A->B->C->D---->Z and then each list element also pointing to an array or another list of all words starting with that letter ..

A -> B -> C -> ...Z
|    |    |
|    |    [Cat, Cave]
|    [Banana, Blob]
[Adam, Apple]

Now is the above approach better or a flat array of [Adam,Apple,Banana,Blob,Cat,Cave] ? Would it even be possible with array ? So a major advantage of link list is you can have an element not just pointing to the next element but also to some other link list/array/ heap/ or any other memory location. Array is a one flat contigous memory sliced into blocks size of the element it is going to store.. Link list on the other hand is a chunks of non-contigous memory units (can be any size and can store anything) and pointing to each other the way you want. Similarly lets say you are making a USB drive. Now would you like files to be saved as any array or as a link list ? I think you get the idea what I am pointing to :)

The problem is with sprintf

sprintf(aa,"%lf",a);

%lf says to interpet "a" as a "long double" (16 bytes) but it is actually a "double" (8 bytes). Use this instead:

sprintf(aa, "%f", a);

My answer differs slightly to @FlavorScape in that I had a single (default export) function in the imported module, I did the following:

import * as functionToTest from 'whatever-lib';

const fooSpy = spyOn(functionToTest, 'default');

The easiest way to do it is to link the CSV-file into the Access database as a table. Then you can work on this table as if it was an ordinary access table, for instance by creating an appropriate query based on this table that returns exactly what you want.

You can link the table either manually or with VBA like this

DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true

UPDATE

Dim db As DAO.Database

' Re-link the CSV Table
Set db = CurrentDb
On Error Resume Next:   db.TableDefs.Delete "tblImport":   On Error GoTo 0
db.TableDefs.Refresh
DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true
db.TableDefs.Refresh

' Perform the import
db.Execute "INSERT INTO someTable SELECT col1, col2, ... FROM tblImport " _
   & "WHERE NOT F1 IN ('A1', 'A2', 'A3')"
db.Close:   Set db = Nothing

i sloved this problem by removing below line from AndroidManifest.xml

I run into this when click on a html , it is fixed by adding type = "button" attribute.

I found this piece of information and got it to work correctly. The data given to me was in string format so I needed to parse the string using kendo.parseDate before formatting it with kendo.toString.

columns: [
    {
        field: "FirstName",
        title: "FIRST NAME"
    },
    {
        field: "LastName",
        title: "LAST NAME"
    },
    {
        field: "DateOfBirth",
        title: "DATE OF BIRTH",
        template: "#= kendo.toString(kendo.parseDate(DateOfBirth, 'yyyy-MM-dd'), 'MM/dd/yyyy') #"
    },
...

Out of experience, I think the correct maximum z-index is 2147483638.

For anyone else having issues when using GNU find binary in a Windows command prompt. The semicolon needs to be escaped with ^

find.exe . -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 ^;

Also you can use Lodash to direct convert object to array:

_.toArray({0:{a:4},1:{a:6},2:{a:5}})
[{a:4},{a:6},{a:5}]

In your case:

_.toArray(subjects).map((subject, i) => (
    <li className="travelcompany-input" key={i}>
        <span className="input-label">Name: {subject[name]}</span>
    </li>
))}

std::less<> when using custom classes with operator<

If you are dealing with a set of your custom class that has operator< defined, then you can just use std::less<>.

As mentioned at http://en.cppreference.com/w/cpp/container/set/find C++14 has added two new find APIs:

template< class K > iterator find( const K& x );
template< class K > const_iterator find( const K& x ) const;

which allow you to do:

main.cpp

#include <cassert>
#include <set>

class Point {
    public:
        // Note that there is _no_ conversion constructor,
        // everything is done at the template level without
        // intermediate object creation.
        //Point(int x) : x(x) {}
        Point(int x, int y) : x(x), y(y) {}
        int x;
        int y;
};
bool operator<(const Point& c, int x) { return c.x < x; }
bool operator<(int x, const Point& c) { return x < c.x; }
bool operator<(const Point& c, const Point& d) {
    return c.x < d;
}

int main() {
    std::set<Point, std::less<>> s;
    s.insert(Point(1, -1));
    s.insert(Point(2, -2));
    s.insert(Point(0,  0));
    s.insert(Point(3, -3));
    assert(s.find(0)->y ==  0);
    assert(s.find(1)->y == -1);
    assert(s.find(2)->y == -2);
    assert(s.find(3)->y == -3);
    // Ignore 1234, find 1.
    assert(s.find(Point(1, 1234))->y == -1);
}

Compile and run:

g++ -std=c++14 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

More info about std::less<> can be found at: What are transparent comparators?

Tested on Ubuntu 16.10, g++ 6.2.0.

You can try the below example. Do use '-' before the width to ensure left indentation. By default they will be right indented; which may not suit your purpose.

System.out.printf("%2d. %-20s $%.2f%n",  i + 1, BOOK_TYPE[i], COST[i]);

As per §2.4 of the XML 1.0 spec, you should be able to use &.

I tried & but this isn't allowed.

Are you sure it isn't a different issue? XML explicitly defines this as the way to escape ampersands.

if you use Google chrome browser you can use like this

<img src="E://bulbpro/pic_bulboff.gif"   width="150px" height="200px">

But if you use Mozila Firefox the you need to add "file " ex.

<img src="file:E://bulbpro/pic_bulboff.gif"   width="150px" height="200px">

Use subprocess.check_output (new in python 2.7). It will suppress stdout and raise an exception if the command fails. (It actually returns the contents of stdout, so you can use that later in your program if you want.) Example:

import subprocess
try:
    subprocess.check_output(['espeak', text])
except subprocess.CalledProcessError:
    # Do something

You can also suppress stderr with:

    subprocess.check_output(["espeak", text], stderr=subprocess.STDOUT)

For earlier than 2.7, use

import os
import subprocess
with open(os.devnull, 'w')  as FNULL:
    try:
        subprocess._check_call(['espeak', text], stdout=FNULL)
    except subprocess.CalledProcessError:
        # Do something

Here, you can suppress stderr with

        subprocess._check_call(['espeak', text], stdout=FNULL, stderr=FNULL)

Here is how to get the code for an embedded image without worrying about any files or base64 statements or mimes (it's still base64, but you don't have to do anything to get it). I originally posted this same answer in this thread, but it may be valuable to repeat it in this one, too.

To do this, you need Mozilla Thunderbird, you can fetch the html code for an image like this:

1. Copy a bitmap to clipboard.
2. Start a new email message.
3. Paste the image. (don't save it as a draft!!!)
4. Double-click on it to get to the image settings dialogue.
5. Look for the "image location" property.
6. Fetch the code and wrap it in an image tag, like this:

You should end up with a string of text something like this:

You can wrap this up into a string variable and place this absolutely anywhere that you would present an html email message - even in your email signatures. The advantage is that there are no attachments, and there are no links. (this code will display a lizard)

A picture is worth a thousand words:

Incidentally, I did write a program to do all of this for you. It's called BaseImage, and it will create the image code as well as the html for you. Please don't consider this self-promotion; I'm just sharing a solution.

If you don't feel like iterating, try FBFriendModel.find({ id:333 }).remove( callback ); or FBFriendModel.find({ id:333 }).remove().exec();

mongoose.model.find returns a Query, which has a remove function.

Update for Mongoose v5.5.3 - remove() is now deprecated. Use deleteOne(), deleteMany() or findOneAndDelete() instead.

You can use SQLAlchemy's or_ function to search in more than one column (the underscore is necessary to distinguish it from Python's own or).

Here's an example:

from sqlalchemy import or_
query = meta.Session.query(User).filter(or_(User.firstname.like(searchVar),
                                            User.lastname.like(searchVar)))

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

base64.b16encode and base64.b16decode convert bytes to and from hex and work across all Python versions. The codecs approach also works, but is less straightforward in Python 3.

Given that you're only converting to ints to then perform a comparison, I'd just switch the table definition around to using varchar also:

Create table #myTempTable
(
num varchar(12)
)
insert into #myTempTable (num) values (1),(2),(3),(4),(5)

and remove all of the attempted CONVERTs from the rest of the query.

 SELECT a.name, a.value AS value, COUNT(*) AS pocet   
 FROM 
 (SELECT item.name, value.value 
  FROM mdl_feedback AS feedback 
  INNER JOIN mdl_feedback_item AS item 
       ON feedback.id = item.feedback
  INNER JOIN mdl_feedback_value AS value 
       ON item.id = value.item 
   WHERE item.typ = 'multichoicerated' AND item.feedback IN (43)
 ) AS a 
 INNER JOIN #myTempTable 
     on a.value = #myTempTable.num
 GROUP BY a.name, a.value ORDER BY a.name

I have encountered with same issue. When I changed content type it has solved. I'm not sure this solution will help you but maybe it is. If you don't mind about content-type, it worked for me.

axios.defaults.headers.post['Content-Type'] ='application/x-www-form-urlencoded';

When there are multiple substrings to remove, one simple and effective option is to use re.sub with a compiled pattern that involves joining all the substrings-to-remove using the regex OR (|) pipe.

import re

to_remove = ['.good', '.bad']
strings = ['Apple.good','Orange.good','Pear.bad']

p = re.compile('|'.join(map(re.escape, to_remove))) # escape to handle metachars
[p.sub('', s) for s in strings]
# ['Apple', 'Orange', 'Pear']

You could create a new array containing that array, so:

<?php
$array = array();
$array['name'] = $oldArray;
?>

Another way is to use a lambda expression. Depending on interpreter version and whether you wish to create a sorted dictionary or sorted key-value tuples (as the OP does), this may even be faster than the accepted answer.

d = {'aa': 3, 'bb': 4, 'cc': 2, 'dd': 1}
s = sorted(d.items(), key=lambda x: x[1], reverse=True)

for k, v in s:
    print(k, v)

You only need to force cscript instead wscript. I always use this template. The function ForceConsole() will execute your vbs into cscript, also you have nice alias to print and scan text.

 Set oWSH = CreateObject("WScript.Shell")
 vbsInterpreter = "cscript.exe"

 Call ForceConsole()

 Function printf(txt)
    WScript.StdOut.WriteLine txt
 End Function

 Function printl(txt)
    WScript.StdOut.Write txt
 End Function

 Function scanf()
    scanf = LCase(WScript.StdIn.ReadLine)
 End Function

 Function wait(n)
    WScript.Sleep Int(n * 1000)
 End Function

 Function ForceConsole()
    If InStr(LCase(WScript.FullName), vbsInterpreter) = 0 Then
        oWSH.Run vbsInterpreter & " //NoLogo " & Chr(34) & WScript.ScriptFullName & Chr(34)
        WScript.Quit
    End If
 End Function

 Function cls()
    For i = 1 To 50
        printf ""
    Next
 End Function

 printf " _____ _ _           _____         _    _____         _     _   "
 printf "|  _  |_| |_ ___ ___|     |_ _ _ _| |  |   __|___ ___|_|___| |_ "
 printf "|     | | '_| . |   |   --| | | | . |  |__   |  _|  _| | . |  _|"
 printf "|__|__|_|_,_|___|_|_|_____|_____|___|  |_____|___|_| |_|  _|_|  "
 printf "                                                       |_|     v1.0"
 printl " Enter your name:"
 MyVar = scanf
 cls
 printf "Your name is: " & MyVar
 wait(5)

Use filter, or if the number of dictionaries in exampleSet is too high, use ifilter of the itertools module. It would return an iterator, instead of filling up your system's memory with the entire list at once:

from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
    print elem

Array.remove() Method

John Resig, creator of jQuery created a very handy Array.remove method that I always use it in my projects.

// Array Remove - By John Resig (MIT Licensed)
Array.prototype.remove = function(from, to) {
  var rest = this.slice((to || from) + 1 || this.length);
  this.length = from < 0 ? this.length + from : from;
  return this.push.apply(this, rest);
};

and here's some examples of how it could be used:

// Remove the second item from the array
array.remove(1);
// Remove the second-to-last item from the array
array.remove(-2);
// Remove the second and third items from the array
array.remove(1,2);
// Remove the last and second-to-last items from the array
array.remove(-2,-1);

As we know jQuery validate plugin invalidates Select field when it has blank value. Why don't we set its value to blank when required.

Yes, you can validate select field with some predefined value.

$("#everything").validate({
    rules: {
        select_field:{
            required: {
                depends: function(element){
                    if('none' == $('#select_field').val()){
                        //Set predefined value to blank.
                        $('#select_field').val('');
                    }
                    return true;
                }
            }
        }
    }
});

We can set blank value for select field but in some case we can't. For Ex: using a function that generates Dropdown field for you and you don't have control over it.

I hope it helps as it helps me.

It is possible of course, use -l: instead of -l. For example -l:libXYZ.a to link with libXYZ.a. Notice the lib written out, as opposed to -lXYZ which would auto expand to libXYZ.

For loops that creates infowindows dynamically, declare a global variable

var openwindow;

and then in the addListenerfunction call (which is within the loop):

google.maps.event.addListener(marker<?php echo $id; ?>, 'click', function() {
if(openwindow){
    eval(openwindow).close();
}
openwindow="myInfoWindow<?php echo $id; ?>";
myInfoWindow<?php echo $id; ?>.open(map, marker<?php echo $id; ?>);
});

Something more to the point for me..

var jsontext = '{"firstname":"Jesper","surname":"Aaberg","phone":["555-0100","555-0120"]}';  
var contact = JSON.parse(jsontext);  
document.write(contact.surname + ", " + contact.firstname);  
document.write(contact.phone[1]);  
// Output:  
// Aaberg, Jesper  
// 555-0100

.PDB file is the short name of "Program Database". It contains the information about debug point for debugger and resources which are used or reference. Its generated when we build as debug mode. Its allow to application to debug at runtime.

The size is increase of .PDB file in debug mode. It is used when we are testing our application.

Good article of pdb file.

This issue has driven me mad: Spring is such a potent tool and yet, such a simple thing as writing an output String as JSON seems impossible without ugly hacks.

My solution (in Kotlin) that I find the least intrusive and most transparent is to use a controller advice and check whether the request went to a particular set of endpoints (REST API typically since we most often want to return ALL answers from here as JSON and not make specializations in the frontend based on whether the returned data is a plain string ("Don't do JSON deserialization!") or something else ("Do JSON deserialization!")). The positive aspect of this is that the controller remains the same and without hacks.

The supports method makes sure that all requests that were handled by the StringHttpMessageConverter(e.g. the converter that handles the output of all controllers that return plain strings) are processed and in the beforeBodyWrite method, we control in which cases we want to interrupt and convert the output to JSON (and modify headers accordingly).

@ControllerAdvice
class StringToJsonAdvice(val ob: ObjectMapper) : ResponseBodyAdvice<Any?> {
    
    override fun supports(returnType: MethodParameter, converterType: Class<out HttpMessageConverter<*>>): Boolean =
        converterType === StringHttpMessageConverter::class.java

    override fun beforeBodyWrite(
        body: Any?,
        returnType: MethodParameter,
        selectedContentType: MediaType,
        selectedConverterType: Class<out HttpMessageConverter<*>>,
        request: ServerHttpRequest,
        response: ServerHttpResponse
    ): Any? {
        return if (request.uri.path.contains("api")) {
            response.getHeaders().contentType = MediaType.APPLICATION_JSON
            ob.writeValueAsString(body)
        } else body
    }
}

I hope in the future that we will get a simple annotation in which we can override which HttpMessageConverter should be used for the output.

Greg Hewgill's approach was missing a few components: the leading "^" to only match the start of the string, and compiling the re beforehand. But this approach will allow you to avoid a try: exept:

import re
INT_RE = re.compile(r"^[-]?\d+$")
def RepresentsInt(s):
    return INT_RE.match(str(s)) is not None

I would be interested why you are trying to avoid try: except?

There is already many of answer, but I m still contributing mine one:

public static IPAddress LocalIpAddress() {
    Func<IPAddress, bool> localIpPredicate = ip =>
        ip.AddressFamily == AddressFamily.InterNetwork &&
        ip.ToString().StartsWith("192.168"); //check only for 16-bit block
    return Dns.GetHostEntry(Dns.GetHostName()).AddressList.LastOrDefault(localIpPredicate);
}

One liner:

public static IPAddress LocalIpAddress() => Dns.GetHostEntry(Dns.GetHostName()).AddressList.LastOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork && ip.ToString().StartsWith("192.168"));

note: Search from last because it still worked after some interfaces added into device, such as MobileHotspot,VPN or other fancy virtual adapters.

I would use Winamp to do this. Create a playlist of files you want to merge into one, select Disk Writer output plugin, choose filename and you're done. The file you will get will be correct MP3 file and you can set bitrate etc.

I found the following to work nicely for me. It doesn't loop and accounts for both height and width. Note that it is important to specify the PX unit when calling setTextSize on the view.

Paint paint = adjustTextSize(getPaint(), numChars, maxWidth, maxHeight);
setTextSize(TypedValue.COMPLEX_UNIT_PX,paint.getTextSize());

Here is the routine I use, passing in the getPaint() from the view. A 10 character string with a 'wide' character is used to estimate the width independent from the actual string.

private static final String text10="OOOOOOOOOO";
public static Paint adjustTextSize(Paint paint, int numCharacters, int widthPixels, int heightPixels) {
    float width = paint.measureText(text10)*numCharacters/text10.length();
    float newSize = (int)((widthPixels/width)*paint.getTextSize());
    paint.setTextSize(newSize);

    // remeasure with font size near our desired result
    width = paint.measureText(text10)*numCharacters/text10.length();
    newSize = (int)((widthPixels/width)*paint.getTextSize());
    paint.setTextSize(newSize);

    // Check height constraints
    FontMetricsInt metrics = paint.getFontMetricsInt();
    float textHeight = metrics.descent-metrics.ascent;
    if (textHeight > heightPixels) {
        newSize = (int)(newSize * (heightPixels/textHeight));
        paint.setTextSize(newSize);
    }

    return paint;
}

First add the long press gesture recognizer to the table view:

UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] 
  initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 2.0; //seconds
lpgr.delegate = self;
[self.myTableView addGestureRecognizer:lpgr];
[lpgr release];

Then in the gesture handler:

-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self.myTableView];

    NSIndexPath *indexPath = [self.myTableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    } else if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
        NSLog(@"long press on table view at row %ld", indexPath.row);
    } else {
        NSLog(@"gestureRecognizer.state = %ld", gestureRecognizer.state);
    }
}

You have to be careful with this so that it doesn't interfere with the user's normal tapping of the cell and also note that handleLongPress may fire multiple times (this will be due to the gesture recognizer state changes).

I get the error in another situation, and here are the problem and the solution:

I have 2 classes derived from a same base class named LevledItem:

public partial class Team : LeveledItem
{
   //Everything is ok here!
}
public partial class Story : LeveledItem
{
   //Everything is ok here!
}

But in their DbContext, I copied some code but forget to change one of the class name:

public class MFCTeamDbContext : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //Other codes here
        modelBuilder.Entity<LeveledItem>()
            .Map<Team>(m => m.Requires("Type").HasValue(ItemType.Team));
    }

public class ProductBacklogDbContext : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //Other codes here
        modelBuilder.Entity<LeveledItem>()
            .Map<Team>(m => m.Requires("Type").HasValue(ItemType.Story));
    }

Yes, the second Map< Team> should be Map< Story>. And it cost me half a day to figure it out!

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

You can use getTime() method to convert the Date to the number of milliseconds since January 1, 1970. Then you can easy do any arithmetic operations with the dates. Of course you can convert the number back to the Date with setTime(). See here an example.

in my case, I Edit my gradle.properties :

note: if u enable the minifyEnabled true :

remove this line :

android.enableR8=true

and add this lines in ur build.gradle , android block :

  dexOptions {
        incremental = true
        preDexLibraries = false
        javaMaxHeapSize "4g" // 2g should be also OK
    }

hope this help some one :)

This worked for me. The key is to use * as Row height.

<Grid x:Name="grid">
        <Grid.RowDefinitions>
            <RowDefinition Height="60"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="10"/>
        </Grid.RowDefinitions>

        <TabControl  Grid.Row="1" x:Name="tabItem">
                <TabItem x:Name="ta" 
                        Header="List of all Clients">
                        <DataGrid Name="clientsgrid" AutoGenerateColumns="True" Margin="2" 
                         ></DataGrid>
                </TabItem>
        </TabControl>
    
    </Grid>

ExpressiveAnnotations gives you such a possibility:

[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }

For reference from SQL Server 2016 SP1+ you could use CREATE OR ALTER VIEW syntax.

MSDN CREATE VIEW:

CREATE [ OR ALTER ] VIEW [ schema_name . ] view_name [ (column [ ,...n ] ) ]   
[ WITH <view_attribute> [ ,...n ] ]   
AS select_statement   
[ WITH CHECK OPTION ]   
[ ; ]

OR ALTER

Conditionally alters the view only if it already exists.

All Func delegates return something; all the Action delegates return void.

Func<TResult> takes no arguments and returns TResult:

public delegate TResult Func<TResult>()

Action<T> takes one argument and does not return a value:

public delegate void Action<T>(T obj)

Action is the simplest, 'bare' delegate:

public delegate void Action()

There's also Func<TArg1, TResult> and Action<TArg1, TArg2> (and others up to 16 arguments). All of these (except for Action<T>) are new to .NET 3.5 (defined in System.Core).

Default is mode ='w'. See documentation.

To complete other answers:

Synchronization is only a worry when the code in your method does one of two things:

1. works with some outside resource that isn't thread safe.
2. Reads or changes a persistent object or class field

This means that variables defined WITHIN your method are always threadsafe. Every call to a method has its own version of these variables. If the method is called by another thread, or by the same thread, or even if the method calls itself (recursion), the values of these variables are not shared.

Thread scheduling is not guaranteed to be round-robin. A task may totally hog the CPU at the expense of threads of the same priority. You can use Thread.yield() to have a conscience. You can use (in java) Thread.setPriority(Thread.NORM_PRIORITY-1) to lower a thread's priority

Plus beware of:

• the large runtime cost (already mentionned by others) on applications that iterate over these "thread-safe" structures.
• Thread.sleep(5000) is supposed to sleep for 5 seconds. However, if somebody changes the system time, you may sleep for a very long time or no time at all. The OS records the wake up time in absolute form, not relative.

None of the above methods worked for me. If you are on Windows, try this on PyCharm terminal:

setx YOUR_VAR "VALUE"

You can access it in your scripts using os.environ['YOUR_VAR'].

I would recommend to debug and find which constraint is "the one you don't want". Suppose you have following issue:

Always the problem is how to find following Constraints and Views.

There are two solutions how to do this:

1. DEBUG VIEW HIERARCHY (Do not recommend this way)

Since you know where to find unexpected constraints (PBOUserWorkDayHeaderView) there is a way to do this fairly well. Lets find UIView and NSLayoutConstraint in red rectangles. Since we know their id in memory it is quite easy.

• Stop app using Debug View Hierarchy:

• Find the proper UIView:

• The next is to find NSLayoutConstraint we care about:

As you can see, the memory pointers are the same. So we know what is going on now. Additionally you can find NSLayoutConstraint in view hierarchy. Since it is selected in View, it selected in Navigator also.

If you need you may also print it on console using address pointer:

(lldb) po 0x17dce920
<UIView: 0x17dce920; frame = (10 30; 300 24.5); autoresize = RM+BM; layer = <CALayer: 0x17dce9b0>>

You can do the same for every constraint the debugger will point to you:-) Now you decide what to do with this.

2. PRINT IT BETTER (I really recommend this way, this is of Xcode 7)

   • set unique identifier for every constraint in your view:

• create simple extension for NSLayoutConstraint:

SWIFT:

extension NSLayoutConstraint {

    override public var description: String {
        let id = identifier ?? ""
        return "id: \(id), constant: \(constant)" //you may print whatever you want here
    }
}

OBJECTIVE-C

@interface NSLayoutConstraint (Description)

@end

@implementation NSLayoutConstraint (Description)

-(NSString *)description {
    return [NSString stringWithFormat:@"id: %@, constant: %f", self.identifier, self.constant];
}

@end

• build it once again, and now you have more readable output for you:

• once you got your id you can simple tap it in your Find Navigator:

• and quickly find it:

HOW TO SIMPLE FIX THAT CASE?

• try to change priority to 999 for broken constraint.

When a variable is declared static inside a class then it becomes a shared variable for all objects of that class which means that the variable is longer specific to any object. For example: -

#include<iostream.h>
#include<conio.h>
class test
{
    void fun()
    {
        static int a=0;
        a++;
        cout<<"Value of a = "<<a<<"\n";
    }
};
void main()
{
    clrscr();
    test obj1;
    test obj2;
    test obj3;
    obj1.fun();
    obj2.fun();
    obj3.fun();
    getch();
}

This program will generate the following output: -

Value of a = 1
Value of a = 2
Value of a = 3

The same goes for globally declared static variable. The above code will generate the same output if we declare the variable a outside function void fun()

Whereas if u remove the keyword static and declare a as a non-static local/global variable then the output will be as follows: -

Value of a = 1
Value of a = 1
Value of a = 1

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))
df
##   b c d
## 1 1 2 3
## 2 1 2 3
## 3 1 2 3

df <- data.frame(a = c(0, 0, 0), df)
df
##   a b c d
## 1 0 1 2 3
## 2 0 1 2 3
## 3 0 1 2 3

Yes, it’s frustrating—sometimes type and other programs print gibberish, and sometimes they do not.

First of all, Unicode characters will only display if the current console font contains the characters. So use a TrueType font like Lucida Console instead of the default Raster Font.

But if the console font doesn’t contain the character you’re trying to display, you’ll see question marks instead of gibberish. When you get gibberish, there’s more going on than just font settings.

When programs use standard C-library I/O functions like printf, the program’s output encoding must match the console’s output encoding, or you will get gibberish. chcp shows and sets the current codepage. All output using standard C-library I/O functions is treated as if it is in the codepage displayed by chcp.

Matching the program’s output encoding with the console’s output encoding can be accomplished in two different ways:

• A program can get the console’s current codepage using chcp or GetConsoleOutputCP, and configure itself to output in that encoding, or

• You or a program can set the console’s current codepage using chcp or SetConsoleOutputCP to match the default output encoding of the program.

However, programs that use Win32 APIs can write UTF-16LE strings directly to the console with WriteConsoleW. This is the only way to get correct output without setting codepages. And even when using that function, if a string is not in the UTF-16LE encoding to begin with, a Win32 program must pass the correct codepage to MultiByteToWideChar. Also, WriteConsoleW will not work if the program’s output is redirected; more fiddling is needed in that case.

type works some of the time because it checks the start of each file for a UTF-16LE Byte Order Mark (BOM), i.e. the bytes 0xFF 0xFE. If it finds such a mark, it displays the Unicode characters in the file using WriteConsoleW regardless of the current codepage. But when typeing any file without a UTF-16LE BOM, or for using non-ASCII characters with any command that doesn’t call WriteConsoleW—you will need to set the console codepage and program output encoding to match each other.

How can we find this out?

Here’s a test file containing Unicode characters:

ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

Here’s a Java program to print out the test file in a bunch of different Unicode encodings. It could be in any programming language; it only prints ASCII characters or encoded bytes to stdout.

import java.io.*;

public class Foo {

    private static final String BOM = "\ufeff";
    private static final String TEST_STRING
        = "ASCII     abcde xyz\n"
        + "German    äöü ÄÖÜ ß\n"
        + "Polish    aezznl\n"
        + "Russian   ??????? ???\n"
        + "CJK       ??\n";

    public static void main(String[] args)
        throws Exception
    {
        String[] encodings = new String[] {
            "UTF-8", "UTF-16LE", "UTF-16BE", "UTF-32LE", "UTF-32BE" };

        for (String encoding: encodings) {
            System.out.println("== " + encoding);

            for (boolean writeBom: new Boolean[] {false, true}) {
                System.out.println(writeBom ? "= bom" : "= no bom");

                String output = (writeBom ? BOM : "") + TEST_STRING;
                byte[] bytes = output.getBytes(encoding);
                System.out.write(bytes);
                FileOutputStream out = new FileOutputStream("uc-test-"
                    + encoding + (writeBom ? "-bom.txt" : "-nobom.txt"));
                out.write(bytes);
                out.close();
            }
        }
    }
}

The output in the default codepage? Total garbage!

However, what if we type the files that got saved? They contain the exact same bytes that were printed to the console.

The only thing that works is UTF-16LE file, with a BOM, printed to the console via type.

If we use anything other than type to print the file, we get garbage:

Z:\andrew\projects\sx\1259084>copy uc-test-UTF-16LE-bom.txt CON
 ¦A S C I I           a b c d e   x y z

 C J K               `O}Y
         1 file(s) copied.

From the fact that copy CON does not display Unicode correctly, we can conclude that the type command has logic to detect a UTF-16LE BOM at the start of the file, and use special Windows APIs to print it.

We can see this by opening cmd.exe in a debugger when it goes to type out a file:

After type opens a file, it checks for a BOM of 0xFEFF—i.e., the bytes 0xFF 0xFE in little-endian—and if there is such a BOM, type sets an internal fOutputUnicode flag. This flag is checked later to decide whether to call WriteConsoleW.

But that’s the only way to get type to output Unicode, and only for files that have BOMs and are in UTF-16LE. For all other files, and for programs that don’t have special code to handle console output, your files will be interpreted according to the current codepage, and will likely show up as gibberish.

You can emulate how type outputs Unicode to the console in your own programs like so:

#include <stdio.h>
#define UNICODE
#include <windows.h>

static LPCSTR lpcsTest =
    "ASCII     abcde xyz\n"
    "German    äöü ÄÖÜ ß\n"
    "Polish    aezznl\n"
    "Russian   ??????? ???\n"
    "CJK       ??\n";

int main() {
    int n;
    wchar_t buf[1024];

    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    n = MultiByteToWideChar(CP_UTF8, 0,
            lpcsTest, strlen(lpcsTest),
            buf, sizeof(buf));

    WriteConsole(hConsole, buf, n, &n, NULL);

    return 0;
}

This program works for printing Unicode on the Windows console using the default codepage.

For the sample Java program, we can get a little bit of correct output by setting the codepage manually, though the output gets messed up in weird ways:

Z:\andrew\projects\sx\1259084>chcp 65001
Active code page: 65001

Z:\andrew\projects\sx\1259084>java Foo
== UTF-8
= no bom
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl

CJK       ??
  ??
?
?
== UTF-16LE

A S C I I           a b c d e   x y z
…

However, a C program that sets a Unicode UTF-8 codepage:

#include <stdio.h>
#include <windows.h>

int main() {
    int c, n;
    UINT oldCodePage;
    char buf[1024];

    oldCodePage = GetConsoleOutputCP();
    if (!SetConsoleOutputCP(65001)) {
        printf("error\n");
    }

    freopen("uc-test-UTF-8-nobom.txt", "rb", stdin);
    n = fread(buf, sizeof(buf[0]), sizeof(buf), stdin);
    fwrite(buf, sizeof(buf[0]), n, stdout);

    SetConsoleOutputCP(oldCodePage);

    return 0;
}

does have correct output:

Z:\andrew\projects\sx\1259084>.\test
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

The moral of the story?

• type can print UTF-16LE files with a BOM regardless of your current codepage
• Win32 programs can be programmed to output Unicode to the console, using WriteConsoleW.
• Other programs which set the codepage and adjust their output encoding accordingly can print Unicode on the console regardless of what the codepage was when the program started
• For everything else you will have to mess around with chcp, and will probably still get weird output.

The use of levels is really up tp you. You need to decide what is severe in your application, what is a warning and what is just information.

You're asking for a comparison between a procedural language and a functional language so I feel your question can be answered here: What is the difference between procedural programming and functional programming?

As to why MS created F# the answer is simply: Creating a functional language with access to the .Net library simply expanded their market base. And seeing how the syntax is nearly identical to OCaml, it really didn't require much effort on their part.

Under Visual Studio 2008, it defaults to an __int64 unless you define _USE_32BIT_TIME_T. You're better off just pretending that you don't know what it's defined as, since it can (and will) change from platform to platform.

I originally intentionally never learned how to use eval, because most people will recommend to stay away from it like the plague. However I recently discovered a use case that made me facepalm for not recognizing it sooner.

If you have cron jobs that you want to run interactively to test, you might view the contents of the file with cat, and copy and paste the cron job to run it. Unfortunately, this involves touching the mouse, which is a sin in my book.

Lets say you have a cron job at /etc/cron.d/repeatme with the contents:

*/10 * * * * root program arg1 arg2

You cant execute this as a script with all the junk in front of it, but we can use cut to get rid of all the junk, wrap it in a subshell, and execute the string with eval

eval $( cut -d ' ' -f 6- /etc/cron.d/repeatme)

The cut command only prints out the 6th field of the file, delimited by spaces. Eval then executes that command.

I used a cron job here as an example, but the concept is to format text from stdout, and then evaluate that text.

The use of eval in this case is not insecure, because we know exactly what we will be evaluating before hand.

By their very nature, references can only be set at the time they are created; i.e., the following two lines have very different effects:

int & A = B;   // makes A an alias for B
A = C;         // assigns value of C to B.

Futher, this is illegal:

int & D;       // must be set to a int variable.

However, when you create a vector, there is no way to assign values to it's items at creation. You are essentially just making a whole bunch of the last example.

$(document).ready(function() {
    $(".tab").click(function () {
        if(!$(this).hasClass('active'))
        {
            $(".tab.active").removeClass("active");
            $(this).addClass("active");        
        }
    });
});

You can use

catch(...)

but that is very dangerous. In his book Debugging Windows, John Robbins tells a war story about a really nasty bug that was masked by a catch(...) command. You're much better off catching specific exceptions. Catch whatever you think your try block might reasonably throw, but let the code throw an exception higher up if something really unexpected happens.

Alternate solution of the values check

//Duplicate Title Entry 
    $.each(ar , function (i, val) {
        if ( jQuery("input:first").val()== val) alert('VALUE FOUND'+Valuecheck);
  });

If RVM was installed with dedicated ubuntu RVM installer https://github.com/rvm/ubuntu_rvm the path to RVM scripts will be different /usr/share/rvm/scripts/rvm. So to add it to your .bashrc run the following command:

echo 'source "/usr/share/rvm/scripts/rvm"' >> ~/.bashrc

It should be:

cursor.execute ("""
   UPDATE tblTableName
   SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
   WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))

You can also do it with basic string manipulation,

cursor.execute ("UPDATE tblTableName SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s WHERE Server='%s' " % (Year, Month, Day, Hour, Minute, ServerID))

but this way is discouraged because it leaves you open for SQL Injection. As it's so easy (and similar) to do it the right way^tm. Do it correctly.

The only thing you should be careful, is that some database backends don't follow the same convention for string replacement (SQLite comes to mind).

Do you have to use Bootstrap for this? Here's a basic HTML/CSS example for obtaining this look that doesn't use any Bootstrap:

HTML:

<div class="bottom">
    <div class="box-content right">Rich Media Ad Production</div>
    <div class="box-content right">Web Design & Development</div>
    <div class="box-content right">Mobile Apps Development</div>
    <div class="box-content">Creative Design</div>
</div>
<div>
    <div class="box-content right">Web Analytics</div>
    <div class="box-content right">Search Engine Marketing</div>
    <div class="box-content right">Social Media</div>
    <div class="box-content">Quality Assurance</div>
</div>

CSS:

.box-content {
    display: inline-block;
    width: 200px;
    padding: 10px;
}

.bottom {
    border-bottom: 1px solid #ccc;
}

.right {
    border-right: 1px solid #ccc;
}

Here is the working Fiddle.

UPDATE

If you must use Bootstrap, here is a semi-responsive example that achieves the same effect, although you may need to write a few additional media queries.

HTML:

<div class="row">
    <div class="col-xs-3">Rich Media Ad Production</div>
    <div class="col-xs-3">Web Design & Development</div>
    <div class="col-xs-3">Mobile Apps Development</div>
    <div class="col-xs-3">Creative Design</div>
</div>
<div class="row">
    <div class="col-xs-3">Web Analytics</div>
    <div class="col-xs-3">Search Engine Marketing</div>
    <div class="col-xs-3">Social Media</div>
    <div class="col-xs-3">Quality Assurance</div>
</div>

CSS:

.row:not(:last-child) {
    border-bottom: 1px solid #ccc;
}

.col-xs-3:not(:last-child) {
    border-right: 1px solid #ccc;
}

Here is another working Fiddle.

Note:

Note that you may also use the <hr> element to insert a horizontal divider in Bootstrap as well if you'd like.

That's a great example. When &current is parsed into a text node it is converted to ¤t. When parsed into an attribute value, it is parsed as &current.

If you want &current in a text node, you should write &current in your markup.

The gory details are in the HTML5 parsing spec - Named Character Reference State

Like this:

my_function (content) // for content only
my_function (content, options) // for both

This has been interesting to read. I have been pondering the same question myself, and the benefits of thinking about it are this:

• Trying to imagine how to implement OOP concepts in a non-OOP language helps me understand the strengths of the OOp language (in my case, C++). This helps give me better judgement about whether to use C or C++ for a given type of application -- where the benefits of one out-weighs the other.

• In my browsing the web for information and opinions on this I found an author who was writing code for an embedded processor and only had a C compiler available: http://www.eetimes.com/discussion/other/4024626/Object-Oriented-C-Creating-Foundation-Classes-Part-1

In his case, analyzing and adapting OOP concepts in plain C was a valid pursuit. It appears he was open to sacrificing some OOP concepts due to the performance overhead hit resulting from attempting to implement them in C.

The lesson I've taken is, yes it can be done to a certain degree, and yes, there are some good reasons to attempt it.

In the end, the machine is twiddling stack pointer bits, making the program counter jump around and calculating memory access operations. From the efficiency standpoint, the fewer of these calculations done by your program, the better... but sometimes we have to pay this tax simply so we can organize our program in a way that makes it least susceptible to human error. The OOP language compiler strives to optimize both aspects. The programmer has to be much more careful implementing these concepts in a language like C.

The best way to check for a null values is

if ( testVar !== null )
{
    // do action here
}

and for undefined

if ( testVar !== undefined )
{
    // do action here
}

You can assign a avariable with undefined.

testVar = undefined;
//typeof(testVar) will be equal to undefined.

This is what worked for me

curl --form file='@filename' URL

It seems when I gave this answer (4+ years ago), I didn't really understand the question, or how form fields worked. I was just answering based on what I had tried in a difference scenario, and it worked for me.

So firstly, the only mistake the OP made was in not using the @ symbol before the file name. Secondly, my answer which uses file=... only worked for me because the form field I was trying to do the upload for was called file. If your form field is called something else, use that name instead.

Explanation

From the curl manpages; under the description for the option --form it says:

This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.

Chances are that if you are trying to do a form upload, you will most likely want to use the @ prefix to upload the file rather than < which uploads the contents of the file.

Addendum

Now I must also add that one must be careful with using the < symbol because in most unix shells, < is the input redirection symbol [which coincidentally will also supply the contents of the given file to the command standard input of the program before <]. This means that if you do not properly escape that symbol or wrap it in quotes, you may find that your curl command does not behave the way you expect.

On that same note, I will also recommend quoting the @ symbol.

You may also be interested in this other question titled: application/x-www-form-urlencoded or multipart/form-data?

I say this because curl offers other ways of uploading a file, but they differ in the content-type set in the header. For example the --data option offers a similar mechanism for uploading files as data, but uses a different content-type for the upload.

Anyways that's all I wanted to say about this answer since it started to get more upvotes. I hope this helps erase any confusions such as the difference between this answer and the accepted answer. There is really none, except for this explanation.

The best way to view and manage your Android app database is to use the library DatabaseManager_For_Android.

It's a single Java activity file; just add it to your source folder. You can view the tables in your app database, update, delete, insert rows to you table. Everything from inside your app.

When the development is done remove the Java file from your src folder. That's it.

You can view the 5 minute demo, Database Manager for Android SQLite Database .

I got this error when my server ran out of disk space and closed the connection midway during generating the response and simply closed the connection

The Uri.parse(extras.getString("imageUri")) was causing an error:

java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Intent android.content.Intent.putExtra(java.lang.String, android.os.Parcelable)' on a null object reference 

So I changed to the following:

intent.putExtra("imageUri", imageUri)

and

Uri uri = (Uri) getIntent().get("imageUri");

This solved the problem.

iOS 7 default blue color is R:0.0 G:122.0 B:255.0

UIColor *ios7BlueColor = [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0];

You have to be more precise, using parentheses, otherwise Java will not use the order of operands that you want it to use.

if ((a[0] & 1 == 0) && (a[1] & 1== 0) && (a[2] & 1== 0)){

Becomes

if (((a[0] & 1) == 0) && ((a[1] & 1) == 0) && ((a[2] & 1) == 0)){

If you are using laragon open the php.ini

In the interface of laragon menu-> php-> php.ini

when you open the file look for ; extension_dir = "./"

create another one without **; ** with the path of your php version to the folder ** ext ** for example

extension_dir = "C: \ laragon \ bin \ php \ php-7.3.11-Win32-VC15-x64 \ ext"

change it save it

Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:

String to match: "my word"

String to search: "I'm searching for my funny words inside this text"

You need the following regex: /^(?=.*my)(?=.*word).*$/im

Explaining:

^ assert position at start of a line

?= Positive Lookahead

.* matches any character (except newline)

() Groups

$ assert position at end of a line

i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])

m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)

Test the Regex here: https://regex101.com/r/iS5jJ3/1

So, you can create a javascript function that:

1. Replace regex reserved characters to avoid errors
2. Split your string at spaces
3. Encapsulate your words inside regex groups
4. Create a regex pattern
5. Execute the regex match

Example:

function fullTextCompare(myWords, toMatch){_x000D_
    //Replace regex reserved characters_x000D_
    myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
    //Split your string at spaces_x000D_
    arrWords = myWords.split(" ");_x000D_
    //Encapsulate your words inside regex groups_x000D_
    arrWords = arrWords.map(function( n ) {_x000D_
        return ["(?=.*"+n+")"];_x000D_
    });_x000D_
    //Create a regex pattern_x000D_
    sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
    //Execute the regex match_x000D_
    return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
    fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
    fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);

Just a a bit modifications on reading string from a file method for more performance

private String readFromFile(Context context, String fileName) {
    if (context == null) {
        return null;
    }

    String ret = "";

    try {
        InputStream inputStream = context.openFileInput(fileName);

        if ( inputStream != null ) {
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream);               

            int size = inputStream.available();
            char[] buffer = new char[size];

            inputStreamReader.read(buffer);

            inputStream.close();
            ret = new String(buffer);
        }
    }catch (Exception e) {
        e.printStackTrace();
    }

    return ret;
}

For those unable to configure the mysql environment (e.g. due to lack of SUPER access) to use human-friendly timezone names like "America/Denver" or "GMT" you can also use the function with numeric offsets like this:

CONVERT_TZ(date,'+00:00','-07:00')

Addition: SQL Server 2012 shows some improved performance in this area but doesn't seem to tackle the specific issues noted below. This should apparently be fixed in the next major version after SQL Server 2012!

Your plan shows the single inserts are using parameterised procedures (possibly auto parameterised) so parse/compile time for these should be minimal.

I thought I'd look into this a bit more though so set up a loop (script) and tried adjusting the number of VALUES clauses and recording the compile time.

I then divided the compile time by the number of rows to get the average compile time per clause. The results are below

Up until 250 VALUES clauses present the compile time / number of clauses has a slight upward trend but nothing too dramatic.

But then there is a sudden change.

That section of the data is shown below.

The cached plan size which had been growing linearly suddenly drops but CompileTime increases 7 fold and CompileMemory shoots up. This is the cut off point between the plan being an auto parametrized one (with 1,000 parameters) to a non parametrized one. Thereafter it seems to get linearly less efficient (in terms of number of value clauses processed in a given time).

Not sure why this should be. Presumably when it is compiling a plan for specific literal values it must perform some activity that does not scale linearly (such as sorting).

It doesn't seem to affect the size of the cached query plan when I tried a query consisting entirely of duplicate rows and neither affects the order of the output of the table of the constants (and as you are inserting into a heap time spent sorting would be pointless anyway even if it did).

Moreover if a clustered index is added to the table the plan still shows an explicit sort step so it doesn't seem to be sorting at compile time to avoid a sort at run time.

I tried to look at this in a debugger but the public symbols for my version of SQL Server 2008 don't seem to be available so instead I had to look at the equivalent UNION ALL construction in SQL Server 2005.

A typical stack trace is below

So going off the names in the stack trace it appears to spend a lot of time comparing strings.

This KB article indicates that DeriveNormalizedGroupProperties is associated with what used to be called the normalization stage of query processing

This stage is now called binding or algebrizing and it takes the expression parse tree output from the previous parse stage and outputs an algebrized expression tree (query processor tree) to go forward to optimization (trivial plan optimization in this case) [ref].

I tried one more experiment (Script) which was to re-run the original test but looking at three different cases.

1. First Name and Last Name Strings of length 10 characters with no duplicates.
2. First Name and Last Name Strings of length 50 characters with no duplicates.
3. First Name and Last Name Strings of length 10 characters with all duplicates.

It can clearly be seen that the longer the strings the worse things get and that conversely the more duplicates the better things get. As previously mentioned duplicates don't affect the cached plan size so I presume that there must be a process of duplicate identification when constructing the algebrized expression tree itself.

Edit

One place where this information is leveraged is shown by @Lieven here

SELECT * 
FROM (VALUES ('Lieven1', 1),
             ('Lieven2', 2),
             ('Lieven3', 3))Test (name, ID)
ORDER BY name, 1/ (ID - ID) 

Because at compile time it can determine that the Name column has no duplicates it skips ordering by the secondary 1/ (ID - ID) expression at run time (the sort in the plan only has one ORDER BY column) and no divide by zero error is raised. If duplicates are added to the table then the sort operator shows two order by columns and the expected error is raised.
