I got the same error with something like:

Set rs = dbs.OpenRecordset _
( _
  "SELECT Field1, Field2, FieldN " _
  & "FROM Query1 " _
  & "WHERE Query2.Field1 = """ & Value1 & """;" _
, dbOpenSnapshot _
)

I fixed the error by replacing "Query1" with "Query2"

Try this:

MyObject obj = new MyObject();
if(obj instanceof MyObject){System.out.println("true");} //true

Because of inheritance this is valid for interfaces, too:

class Animal {}
class Dog extends Animal {}    

Dog obj = new Dog();
Animal animal = new Dog();
if(obj instanceof Animal){System.out.println("true");} //true
if(animal instanceof Animal){System.out.println("true");} //true
if(animal instanceof Dog){System.out.println("true");} //true

Ideally runtime exceptions should not be thrown. A checked exception(business exception) should be created for your scenario. Because if either of these exception is thrown and logged, it misguides the developer while going through the logs. Instead business exceptions do not create that panic and usually ignored while troubleshooting logs.

I had trouble finding the applicationhost.config file. It was in c:\windows\System32\inetsrv\ (Server2008) or the c:\windows\System32\inetsrv\config\ (Server2008r2).

After I changed that setting, I also had to change the way IIS loads the aspnet_filter.dll. Open the IIS Manager, go under "Sites", "SharePoint - 80", in the "IIS" grouping, under the "ISAPI Filters", make sure that all of the "Executable" paths point to ...Microsoft.NET\Framework64\v#.#.####\aspnet_filter.dll. Some of mine were pointed to the \Framework\ (not 64).

You also need to restart the WWW service to reload the new settings.

If it is giving you relay access denied when you are trying to send an email from outside your network to a domain that your server is not authoritative for then it means your receive connector does not grant you the permissions for sending/relaying. Most likely what you need to do is to authenticate to the server to be granted the permissions for relaying but that does depend upon the configuration of your receive connector. In Exchange 2007/2010/2013 you would need to enable ExchangeUsers permission group as well as an authentication mechanism such as Basic authentication.

Once you're sure your receive connector is configured make sure your email client is configured for authentication as well for the SMTP server. It depends upon your server setup but normally for Exchange you would configure the username by itself, no need for the domain to appended or prefixed to it.

To test things out with authentication via telnet you can go over my post here for directions: https://jefferyland.wordpress.com/2013/05/28/essential-exchange-troubleshooting-send-email-via-telnet/

On windows forms it is available, at the top of the class put

  static void Main(string[] args)
    {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
       //other stuff here
    }

since windows is single threaded, its all you need, in the event its a service you need to put it right above the call to the service (since there is no telling what thread you'll be on).

using System.Security.Principal 

is also needed.

This single step worked for me... No 2-step verification. As I had created a dummy account for my local development, so I was OK with this setting. Make sure you only do this if your account contains NO personal or any critical data. This is just another way of tackling this error and NOT secure.

I turned ON the setting to alow less secured apps to be allowed access. Form here : https://myaccount.google.com/lesssecureapps

The settings file is never created automatically, you must create it yourself, whether you use embedded or "real" maven.

Create it at the following location <your home folder>/.m2/settings.xml e.g. C:\Users\YourUserName\.m2\settings.xml on Windows or /home/YourUserName/.m2/settings.xml on Linux

Here's an empty skeleton you can use:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies/>
  <profiles/>
  <activeProfiles/>
</settings>

If you use Eclipse to edit it, it will give you auto-completion when editing it.

And here's the Maven settings.xml Reference page

Set the application pool to 2.0, I did it and worked.

This code has worked for me:

WebClient wc = new WebClient();
wc.Proxy.Credentials = CredentialCache.DefaultCredentials;

Fistly, Code Blocks is not a compiler. It is just an integrated development environment.

So, you must show the path of your compiler at first, (if you dont have a compiler you have to download an install, it is not difficult to find. f.e. GCC is good one.) If code blocks could not find automatically the path of compiler it is an obligation to show it yourself.

But when you install, probably Code Blocks automatically find your compiler.

Enjoy.

In order to checkout a git tag , you would execute the following command

git checkout tags/tag-name -b branch-name

eg as mentioned below.

 git checkout tags/v1.0 -b v1.0-branch

To fetch the all tags use the command

git fetch --all --tags

One example of when I found it convenient was when trying to embed binary data in XML. Some of the binary data was being misinterpreted by the SAX parser because that data could be literally anything, including XML special characters. Base64 encoding the data on the transmitting end and decoding it on the receiving end fixed that problem.

Java implicitly assumes a reference to the current object for methods called like this. So

// Test2.java
public class Test2 {
    public void testMethod() {
        testMethod2();
    }

    // ...
}

Is exactly the same as

// Test2.java
public class Test2 {
    public void testMethod() {
        this.testMethod2();
    }

    // ...
}

I prefer the second version to make more clear what you want to do.

i was looking for the same. and found this solution.

Use negative regex assertion:

location ~ ^/(?!(favicon\.ico|resources|robots\.txt)) { 
.... # your stuff 
} 

Source Negated Regular Expressions in location

Explanation of Regex :

If URL does not match any of the following path

example.com/favicon.ico
example.com/resources
example.com/robots.txt

Then it will go inside that location block and will process it.

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

You can use this code:

    $('#country').select2("val", "Your_value").trigger('change');

Put your desired value instead of Your_value

Hope It will work :)

the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.

I am late to the party, but for option #1, I would go with IdentityServer3(.NET 4.6 or below) or IdentityServer4 (compatible with Core) .

You can reuse your existing user store in your app and plug that to be IdentityServer's User Store. Then the clients must be pointed to your IdentityServer as the open id provider.

There is an elegant way in the Airbnb Style Guide to do this (ECMAScript 7):

const myObject = {
  a: 1,
  b: 2,
  c: 3
};
const { a, ...noA } = myObject;
console.log(noA); // => { b: 2, c: 3 }

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

           </executions>
         </plugin>
       </plugins>
     </build>
   </project>
   

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>
</dependency>

On Windows OS without Service.

One case I found where setAttribute is necessary is when changing ARIA attributes, since there are no corresponding properties. For example

x.setAttribute('aria-label', 'Test');
x.getAttribute('aria-label');

There's no x.arialabel or anything like that, so you have to use setAttribute.

Edit: x["aria-label"] does not work. You really do need setAttribute.

x.getAttribute('aria-label')
null
x["aria-label"] = "Test"
"Test"
x.getAttribute('aria-label')
null
x.setAttribute('aria-label', 'Test2')
undefined
x["aria-label"]
"Test"
x.getAttribute('aria-label')
"Test2"

If you want to do this in pgadmin, it is much easier. It seems in postgressql, to add a auto increment to a column, we first need to create a auto increment sequence and add it to the required column. I did like this.

1) Firstly you need to make sure there is a primary key for your table. Also keep the data type of the primary key in bigint or smallint. (I used bigint, could not find a datatype called serial as mentioned in other answers elsewhere)

2)Then add a sequence by right clicking on sequence-> add new sequence. If there is no data in the table, leave the sequence as it is, don't make any changes. Just save it. If there is existing data, add the last or highest value in the primary key column to the Current value in Definitions tab as shown below.

3)Finally, add the line nextval('your_sequence_name'::regclass) to the Default value in your primary key as shown below.

Make sure the sequence name is correct here. This is all and auto increment should work.

Cpp Reference is always helpful!!! Details about explicit specifier can be found here. You may need to look at implicit conversions and copy-initialization too.

Quick look

The explicit specifier specifies that a constructor or conversion function (since C++11) doesn't allow implicit conversions or copy-initialization.

Example as follows:

struct A
{
    A(int) { }      // converting constructor
    A(int, int) { } // converting constructor (C++11)
    operator bool() const { return true; }
};

struct B
{
    explicit B(int) { }
    explicit B(int, int) { }
    explicit operator bool() const { return true; }
};

int main()
{
    A a1 = 1;      // OK: copy-initialization selects A::A(int)
    A a2(2);       // OK: direct-initialization selects A::A(int)
    A a3 {4, 5};   // OK: direct-list-initialization selects A::A(int, int)
    A a4 = {4, 5}; // OK: copy-list-initialization selects A::A(int, int)
    A a5 = (A)1;   // OK: explicit cast performs static_cast
    if (a1) cout << "true" << endl; // OK: A::operator bool()
    bool na1 = a1; // OK: copy-initialization selects A::operator bool()
    bool na2 = static_cast<bool>(a1); // OK: static_cast performs direct-initialization

//  B b1 = 1;      // error: copy-initialization does not consider B::B(int)
    B b2(2);       // OK: direct-initialization selects B::B(int)
    B b3 {4, 5};   // OK: direct-list-initialization selects B::B(int, int)
//  B b4 = {4, 5}; // error: copy-list-initialization does not consider B::B(int,int)
    B b5 = (B)1;   // OK: explicit cast performs static_cast
    if (b5) cout << "true" << endl; // OK: B::operator bool()
//  bool nb1 = b2; // error: copy-initialization does not consider B::operator bool()
    bool nb2 = static_cast<bool>(b2); // OK: static_cast performs direct-initialization
}

There are different ways to do that.

• I created the data frame to showcase the different techniques to filter your data.

df = pd.DataFrame({'Date':['01-Jun-13','03-Jun-13', '15-Aug-13', '20-Jan-14', '21-Feb-14'],

'abc':[100,-20,40,25,60],'xyz':[200,50,-5,15,80] })

• I separated months/year/day and seperated month-year as you explained.

def getMonth(s):
  return s.split("-")[1]

def getDay(s):
  return s.split("-")[0]

def getYear(s):
  return s.split("-")[2]

def getYearMonth(s):
  return s.split("-")[1]+"-"+s.split("-")[2]

• I created new columns: year, month, day and 'yearMonth'. In your case, you need one of both. You can group using two columns 'year','month' or using one column yearMonth

df['year']= df['Date'].apply(lambda x: getYear(x))
df['month']= df['Date'].apply(lambda x: getMonth(x))
df['day']= df['Date'].apply(lambda x: getDay(x))
df['YearMonth']= df['Date'].apply(lambda x: getYearMonth(x))

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
3  20-Jan-14   25   15   14   Jan  20    Jan-14
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• You can go through the different groups in groupby(..) items.

In this case, we are grouping by two columns:

for key,g in df.groupby(['year','month']):
    print key,g

Output:

('13', 'Jun')         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
('13', 'Aug')         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
('14', 'Jan')         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
('14', 'Feb')         Date  abc  xyz year month day YearMonth

In this case, we are grouping by one column:

for key,g in df.groupby(['YearMonth']):
    print key,g

Output:

Jun-13         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
Aug-13         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
Jan-14         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
Feb-14         Date  abc  xyz year month day YearMonth
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• In case you wanna access to specific item, you can use get_group

print df.groupby(['YearMonth']).get_group('Jun-13')

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

• Similar to get_group. This hack would help to filter values and get the grouped values.

This also would give the same result.

print df[df['YearMonth']=='Jun-13'] 

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

You can select list of abc or xyz values during Jun-13

print df[df['YearMonth']=='Jun-13'].abc.values
print df[df['YearMonth']=='Jun-13'].xyz.values

Output:

[100 -20]  #abc values
[200  50]  #xyz values

You can use this to go through the dates that you have classified as "year-month" and apply cretiria on it to get related data.

for x in set(df.YearMonth): 
    print df[df['YearMonth']==x].abc.values
    print df[df['YearMonth']==x].xyz.values

I recommend also to check this answer as well.

Pure JS solution is as follows:

function clearForm(myFormElement) {

  var elements = myFormElement.elements;

  myFormElement.reset();

  for(i=0; i<elements.length; i++) {

  field_type = elements[i].type.toLowerCase();

  switch(field_type) {

    case "text":
    case "password":
    case "textarea":
          case "hidden":

      elements[i].value = "";
      break;

    case "radio":
    case "checkbox":
        if (elements[i].checked) {
          elements[i].checked = false;
      }
      break;

    case "select-one":
    case "select-multi":
                elements[i].selectedIndex = -1;
      break;

    default:
      break;
  }
    }
}

The .encode method gets applied to a Unicode string to make a byte-string; but you're calling it on a byte-string instead... the wrong way 'round! Look at the codecs module in the standard library and codecs.open in particular for better general solutions for reading UTF-8 encoded text files. However, for the csv module in particular, you need to pass in utf-8 data, and that's what you're already getting, so your code can be much simpler:

import csv

def unicode_csv_reader(utf8_data, dialect=csv.excel, **kwargs):
    csv_reader = csv.reader(utf8_data, dialect=dialect, **kwargs)
    for row in csv_reader:
        yield [unicode(cell, 'utf-8') for cell in row]

filename = 'da.csv'
reader = unicode_csv_reader(open(filename))
for field1, field2, field3 in reader:
  print field1, field2, field3 

PS: if it turns out that your input data is NOT in utf-8, but e.g. in ISO-8859-1, then you do need a "transcoding" (if you're keen on using utf-8 at the csv module level), of the form line.decode('whateverweirdcodec').encode('utf-8') -- but probably you can just use the name of your existing encoding in the yield line in my code above, instead of 'utf-8', as csv is actually going to be just fine with ISO-8859-* encoded bytestrings.

I just came across this question while searching for the solution for myself. You might consider calling the system beep function by running some kernel32 stuff.

using System.Runtime.InteropServices;
        [DllImport("kernel32.dll")]
        public static extern bool Beep(int freq, int duration);

        public static void TestBeeps()
        {
            Beep(1000, 1600); //low frequency, longer sound
            Beep(2000, 400); //high frequency, short sound
        }

This is the same as you would run powershell:

[console]::beep(1000, 1600)
[console]::beep(2000, 400)

var value = CKEDITOR.instances['YourInstanceName'].getData()
 alert( value);

Replace YourInstanceName with the name of your instance and you will get the desired results.

Python's if can be used as a ternary operator:

>>> 'true' if True else 'false'
'true'
>>> 'true' if False else 'false'
'false'

very simple answer

Here is a property I use in one of my applications

public List<string> OperationModes
{
    get
    {
       return Enum.GetNames(typeof(SomeENUM)).ToList();
    }
}

If you are only interested in the packages installed globally without the full TREE then:

npm -g ls --depth=0

or locally (omit -g) :

npm ls --depth=0

If you want something that obviously (without looking up esoteric stuff in manuals) works without imports and try/except and works on a fair range of Python 2.x versions (2.2 to 2.6):

def headn(file_name, n):
    """Like *x head -N command"""
    result = []
    nlines = 0
    assert n >= 1
    for line in open(file_name):
        result.append(line)
        nlines += 1
        if nlines >= n:
            break
    return result

if __name__ == "__main__":
    import sys
    rval = headn(sys.argv[1], int(sys.argv[2]))
    print rval
    print len(rval)

Starting from https://github.com/AngularClass/angular-starter, after having tested a lot of different configuration combination, here is what I did to get it working with AoT.

As already said many times, in my app.component.scss:

$fa-font-path: "~font-awesome/fonts" !default;
@import "~font-awesome/scss/font-awesome";

Then in webpack.config.js (actually webpack.commong.js in the starter pack) :

In the plugins section:

new CopyWebpackPlugin([
    { from: 'src/assets', to: 'assets' },
    { from: 'src/meta'},
    { from: 'node_modules/font-awesome/fonts', to: 'assets/fonts/' }
]),

In the rules section:

,
{
    test: /\.(eot|woff2?|svg|ttf)([\?]?.*)$/,
    use: 'file-loader?name=/assets/fonts/[name].[ext]'
}

Web.config file

<connectionStrings>
  <add name="MyConnectionString" connectionString="Data Source=SERGIO-DESKTOP\SQLEXPRESS;    Initial Catalog=YourDatabaseName;Integrated Security=True;"/>
</connectionStrings>

.cs file

System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

I think it would be quite hard to calculate those because the branch target address is determined at run time and that prediction is done in hardware. If you explained the problem a bit more in depth and described what you are trying to do it would be a little easier to help. (:

1. Spring annotations will work fine if you remove enctype="multipart/form-data".

   @RequestParam(value="txtEmail", required=false)
   

2. You can even get the parameters from the request object .

   request.getParameter(paramName);
   

3. Use a form in case the number of attributes are large. It will be convenient. Tutorial to get you started.

4. Configure the Multi-part resolver if you want to receive enctype="multipart/form-data".

   <bean id="multipartResolver"
     class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
       <property name="maxUploadSize" value="250000"/>
   </bean>
   

Refer the Spring documentation.

ptomato's code can also be written in a cleaner manner like:

ifeq ($(TARGET_CPU),x86)
  TARGET_CPU_IS_X86 := 1
else ifeq ($(TARGET_CPU),x86_64)
  TARGET_CPU_IS_X86 := 1
else
  TARGET_CPU_IS_X86 := 0
endif

This doesn't answer OP's question but as it's the top result on google, I'm adding it here in case it's useful to anyone else.

The best way to do it is to use the append function:

package main

import (
    "fmt"
)

func main() {
    x := []int{4, 5, 6, 7, 88}
    fmt.Println(x)
    x = append(x[:2], x[4:]...)//deletes 6 and 7
    fmt.Println(x)
}

https://play.golang.org/p/-EEFCsqse4u

I ran into a similar situation with code that WAS working , then was not.

Turned while dragging / dropping code within a file, I moved an object into another set of braces. Took longer to figure out than I care to admit.

Bit once I move the code back into its proper place, the error resolved.

Just call css with one argument

  $('#idDetails').css('display');

If I understand your question. Otherwise, you want cletus' answer.

This works for me:

int[] list = new int[maximum];
for (int i = 0; i < maximum; i++{
    list[i] = put_input_here;
}

This way, it's simple, yet efficient.

You'll have to write your own extension method to do this:

    public static class CollectionEx
    {
      /// <summary>
      /// Copies the contents of an IEnumerable list to an ObservableCollection
      /// </summary>
      /// <typeparam name="T">The type of objects in the source list</typeparam>
      /// <param name="enumerableList">The source list to be converted</param>
      /// <returns>An ObservableCollection containing the objects from the source list</returns>
      public static ObservableCollection<T> ToObservableCollection<T>( this IEnumerable<T> enumerableList )
      {
        if( enumerableList != null ) {
          // Create an emtpy observable collection object
          var observableCollection = new ObservableCollection<T>();

          // Loop through all the records and add to observable collection object
          foreach( var item in enumerableList ) {
            observableCollection.Add( item );
          }

          // Return the populated observable collection
          return observableCollection;
        }
        return null;
      }
    }

Although fractional pixels may appear to round up on individual elements (as @SkillDrick demonstrates very well) it's important to know that the fractional pixels are actually respected in the actual box model.

This can best be seen when elements are stacked next to (or on top of) each other; in other words, if I were to place 400 0.5 pixel divs side by side, they would have the same width as a single 200 pixel div. If they all actually rounded up to 1px (as looking at individual elements would imply) we'd expect the 200px div to be half as long.

This can be seen in this runnable code snippet:

I had the same problem and solved it by updating the Android SDK Build-Tools in Android Studio.

step 1 - Double shift and type SDK manager, this will open the SDK manager

step 2 - Then on the second tab (SDK Tools), update the Android SDK Build-Tools and the error message should go away.

if this does not resolve check the option in Setting tab,use detected Adb tool in Setting tab

You can create a new alias in Terminal:

nano ~/.bash_profile

Copy this line and paste it into the editor:

alias subl='open -a "Sublime Text"'

Hit control + x, then y, then enter to save and close it.

Close all Terminal windows and open it up again.

That's it, you can now use subl filename or subl .

1. Add Internet permission in Androidmanifest.xml file

uses-permission android:name="android.permission.INTERNET

2. Open cmd in windows
3. type "ipconfig" then press enter
4. find IPv4 Address. . . . . . . . . . . : 192.168.X.X
5. use this URL "http://192.168.X.X:your_virtual_server_port/your_service.php"

Overall

SELECT
       COUNT(DISTINCT `site_id`) as distinct_sites
  FROM `cp_visits`
 WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)

Or per site

  SELECT
         `site_id` as site,
         COUNT(DISTINCT `user_id`) as distinct_users_per_site
    FROM `cp_visits`
   WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`

Having the time column in the result doesn't make sense - since you are aggregating the rows, showing one particular time is irrelevant, unless it is the min or max you are after.

PHP's DateTime class has a useful modify method which takes in easy-to-understand text.

$dateTime = new DateTime('2011-11-17 05:05');
$dateTime->modify('+5 minutes');

You could also use string interpolation or concatenation to parameterize it:

$dateTime = new DateTime('2011-11-17 05:05');
$minutesToAdd = 5;
$dateTime->modify("+{$minutesToAdd} minutes");

You could try this if you want to insert all column using SELECT * INTO table.

SELECT  *
INTO    Table2
FROM    Table1;

The cleanest approach is to use the Array#concat method; it will not create a new array (unlike Array#+ which will do the same thing but create a new array).

Straight from the docs (http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-concat):

concat(other_ary)

Appends the elements of other_ary to self.

So

[1,2].concat([3,4])  #=> [1,2,3,4]  

Array#concat will not flatten a multidimensional array if it is passed in as an argument. You'll need to handle that separately:

arr= [3,[4,5]]
arr= arr.flatten   #=> [3,4,5]
[1,2].concat(arr)  #=> [1,2,3,4,5]

Lastly, you can use our corelib gem (https://github.com/corlewsolutions/corelib) which adds useful helpers to the Ruby core classes. In particular we have an Array#add_all method which will automatically flatten multidimensional arrays before executing the concat.

Update 2020 - Xcode 11

In Xcode 11, you can provide only one image with 1x, 2x, and 3x scales then set it in LaunchScreen.storyboard to fill up the screen and everything goes well!

For Example: (1242pt x 2688pt @1x)

This is the portrait screen size of iPhone 11 Pro Max which is the large iPhone screen size yet so it will give you high-quality splash screen on all iOS devices.

Update 2019 - iOS 12

I have collected all sizes needed for the splash screen. All u need is to just drag images with these sizes and drop them, Xcode will place each size in the right place.

Good luck.

Sizes :

320×480

640×960

640×1136

750×1334

768×1004

768×1024

828×1792

1024×748

1024×768

1125×2436

1242×2208

1242×2688

1536×2008

1536×2048

1792×828

2048×1496

2048×1536

2208×1242

2436×1125

2688×1242

Note

Count of required images are 26 images but there are 6 duplicated sizes so u will find the above sizes are only 20.

Recover with python3 -m pip install --user pip==9.0.1 (or the version that worked)

Based on the last sample I created a method:

private string GetNumberFromString(string sLongString, int iLimitNumbers)
{
    string sReturn = "NA";
    int iNumbersCounter = 0;
    int iCharCounter = 0; 

    string sAlphaChars = string.Empty;
    string sNumbers = string.Empty;
    foreach (char str in sLongString)
    {
        if (char.IsDigit(str))
        {
            sNumbers += str.ToString();
            iNumbersCounter++;
            if (iNumbersCounter == iLimitNumbers)
            {
                return sReturn = sNumbers;
            }
        }
        else
        {
            sAlphaChars += str.ToString();
            iCharCounter++;
            // reset the counter 
            iNumbersCounter = 0; 
        }
    }
    return sReturn;
}

2.0 Compatible Answer: While above mentioned answer explain in detail on how to use GPU on Keras Model, I want to explain how it can be done for Tensorflow Version 2.0.

To know how many GPUs are available, we can use the below code:

print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

To find out which devices your operations and tensors are assigned to, put tf.debugging.set_log_device_placement(True) as the first statement of your program.

Enabling device placement logging causes any Tensor allocations or operations to be printed. For example, running the below code:

tf.debugging.set_log_device_placement(True)

# Create some tensors
a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
c = tf.matmul(a, b)

print(c)

gives the Output shown below:

Executing op MatMul in device /job:localhost/replica:0/task:0/device:GPU:0 tf.Tensor( [[22. 28.] [49. 64.]], shape=(2, 2), dtype=float32)

when referencing images in CSS or in an IMG tag, use image-name.jpg

while the image is really located under ./assets/images/image-name.jpg

You can use webpack to provide it. It will be then injected DOM automatically.

module.exports = {
  context: process.cwd(),
  entry: {
    something: [
      path.join(root, 'src/something.ts')
    ],
    vendor: ['jquery']
  },
  devtool: 'source-map',
  output: {
    path: path.join(root, '/dist/js'),
    sourceMapFilename: "[name].js.map",
    filename: '[name].js'
  },
  module: {
    rules: [
      {test: /\.ts$/, exclude: /node_modules/, loader: 'ts-loader'}
    ]
  },
  resolve: {
    extensions: ['.ts', '.es6', '.js', '.json']
  },
  plugins: [

    new webpack.ProvidePlugin({
      $: 'jquery',
      jQuery: 'jquery'
    }),

  ]
};

Try giving a Width in % to the image in the carousel?

.item img {
    width:100%;
}

for (int i = 1; i < argc; i++) {

    if (strcmp(argv[i],"-i")==0) {
        filename = argv[i+1];
        printf("filename: %s",filename);
    } else if (strcmp(argv[i],"-c")==0) {
        convergence = atoi(argv[i + 1]);
        printf("\nconvergence: %d",convergence);
    } else if (strcmp(argv[i],"-a")==0) {
        accuracy = atoi(argv[i + 1]);
        printf("\naccuracy:%d",accuracy);
    } else if (strcmp(argv[i],"-t")==0) {
        targetBitRate = atof(argv[i + 1]);
        printf("\ntargetBitRate:%f",targetBitRate);
    } else if (strcmp(argv[i],"-f")==0) {
        frameRate = atoi(argv[i + 1]);
        printf("\nframeRate:%d",frameRate);
    }

}

This worked for me-

if(Mage::registry('current_product')->getTypeId() == 'simple' ) {

Use getTypeId()

In my case I was using XAMPP, and there was a log that told me the error. To find it, go to the XAMPP control panel, and click "Configure" for MySQL, then click on "Open Log."

The most current data of the log is at the bottom, and the log is organized by date, time, some number, and text in brackets that may say "Note" or "Error." One that says "Error" is likely causing the issue.

For me, my error was a tablespace that was causing an issue, so I deleted the database files at the given location.

Note: The tablespace files for your installation of XAMPP may be at a different location, but they were in /opt/lampp/var/mysql for me. I think that's typical of XAMPP on Debian-based distributions. Also, my instructions on what to click in the control panel to see the log may be a bit different for you because I'm running XAMPP on an Ubuntu-based distribution of Linux (Feren OS).

To get all substring.

var out = []; 'MyLongString:StringIWant;'
.replace(/(:)\w+(;)+/g, (e) => {
    out.push(e.replace(':', '').replace(';', ''))
    return e;
});
console.log(out[0])

Change

private ArrayList finishingOrder;

//Make an ArrayList to hold RaceCar objects to determine winners
finishingOrder = Collections.synchronizedCollection(new ArrayList(numberOfRaceCars)

to

private List finishingOrder;

//Make an ArrayList to hold RaceCar objects to determine winners
finishingOrder = Collections.synchronizedList(new ArrayList(numberOfRaceCars)

List is a supertype of ArrayList so you need to specify that.

Otherwise, what you're doing seems fine. Other option is you can use Vector, which is synchronized, but this is probably what I would do.

Setting a br tag to display: none is helpful, but then you can end up with WordsRunTogether. I've found it more helpful to instead replace it with a space character, like so:

HTML:

<h1>
    Breaking<br />News:<br />BR<br />Considered<br />Harmful!
</h1>

CSS:

@media (min-device-width: 1281px){
    h1 br {content: ' ';}
    h1 br:after {content: ' ';}
}

You need to add a vertical-align property to your two child div's.

If .small is always shorter, you need only apply the property to .small. However, if either could be tallest then you should apply the property to both .small and .big.

.container{ 
    border: 1px black solid;
    width: 320px;
    height: 120px;    
}

.small{
    display: inline-block;
    width: 40%;
    height: 30%;
    border: 1px black solid;
    background: aliceblue; 
    vertical-align: top;   
}

.big {
    display: inline-block;
    border: 1px black solid;
    width: 40%;
    height: 50%;
    background: beige; 
    vertical-align: top;   
}

Vertical align affects inline or table-cell box's, and there are a large nubmer of different values for this property. Please see https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align for more details.

I encountered a similar problem in my project. After struggling a lot, I found this solution:

if ($.datepicker.parseDate("dd/mm/yy","17/06/2015") > $.datepicker.parseDate("dd/mm/yy","20/06/2015"))
    // do something

You DO NOT NEED plugins like jQuery Validate or Moment.js for this issue. Hope this solution helps.

First, array_length should be an integer and not a string:

array_length = len(array_dates)

Second, your for loop should be constructed using range:

for i in range(array_length):  # Use `xrange` for python 2.

Third, i will increment automatically, so delete the following line:

i += 1

Note, one could also just zip the two lists given that they have the same length:

import csv

dates = ['2020-01-01', '2020-01-02', '2020-01-03']
urls = ['www.abc.com', 'www.cnn.com', 'www.nbc.com']

csv_file_patch = '/path/to/filename.csv'

with open(csv_file_patch, 'w') as fout:
    csv_file = csv.writer(fout, delimiter=';', lineterminator='\n')
    result_array = zip(dates, urls)
    csv_file.writerows(result_array)

overflow-x: hidden;

As already written elsewhere:

• For Java 1.5 and later you don't need to do (almost) anything, it's done by the compiler.
• For Java 1.4 and before, use Integer.intValue() to convert from Integer to int.

BUT as you wrote, an Integer can be null, so it's wise to check that before trying to convert to int (or risk getting a NullPointerException).

pstmt.setInt(1, (tempID != null ? tempID : 0));  // Java 1.5 or later

or

pstmt.setInt(1, (tempID != null ? tempID.intValue() : 0));  // any version, no autoboxing  

^* using a default of zero, could also do nothing, show a warning or ...

I mostly prefer not using autoboxing (second sample line) so it's clear what I want to do.

Try this:

package example.spin.spinnerexample;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener{

    String[] bankNames={"BOI","SBI","HDFC","PNB","OBC"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //Getting the instance of Spinner and applying OnItemSelectedListener on it
        Spinner spin = (Spinner) findViewById(R.id.simpleSpinner);
        spin.setOnItemSelectedListener(this);

        //Creating the ArrayAdapter instance having the bank name list
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item,bankNames);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        //Setting the ArrayAdapter data on the Spinner
        spin.setAdapter(aa);
    }


    //Performing action onItemSelected and onNothing selected
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int position,long id) {
        Toast.makeText(getApplicationContext(), bankNames[position], Toast.LENGTH_LONG).show();
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }
}

activity_main.xml:-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    android:paddingRight="@dimen/activity_horizontal_margin"

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

Here is the latest example of how to do it. From react docs, plus auto-binding "fat-arrow" method syntax.

class FlavorForm extends React.Component {
  constructor(props) {
    super(props);
    this.state = {value: 'coconut'};
  }

  handleChange = (event) =>
    this.setState({value: event.target.value});

  handleSubmit = (event) => {
    alert('Your favorite flavor is: ' + this.state.value);
    event.preventDefault();
  }

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <label>
          Pick your favorite flavor:
          <select value={this.state.value} onChange={this.handleChange}>
            <option value="grapefruit">Grapefruit</option>
            <option value="lime">Lime</option>
            <option value="coconut">Coconut</option>
            <option value="mango">Mango</option>
          </select>
        </label>
        <input type="submit" value="Submit" />
      </form>
    );
  }
} 

Sometimes you still need to know if Cookie exists in Response. Then you can check if cookie key exists:

HttpContext.Current.Response.Cookies.AllKeys.Contains("myCookie")

More info can be found here.

In my case I had to modify Response Cookie in Application_EndRequest method in Global.asax. If Cookie doesn't exist I don't touch it:

string name = "myCookie";
HttpContext context = ((HttpApplication)sender).Context;
HttpCookie cookie = null;

if (context.Response.Cookies.AllKeys.Contains(name))
{
    cookie = context.Response.Cookies[name];
}

if (cookie != null)
{
    // update response cookie
}

I had this issue with an image gallery that I wanted to rerender due to changes made on a different tab. So tab1 = imageGallery, tab2 = favoriteImages

tab @change="updateGallery()" -> this forces my v-for directive to process the filteredImages function every time I switch tabs.

<script>
export default {
  data() {
    return {
      currentTab: 0,
      tab: null,
      colorFilter: "",
      colors: ["None", "Beige", "Black"], 
      items: ["Image Gallery", "Favorite Images"]
    };
  },
  methods: {
    filteredImages: function() {
      return this.$store.getters.getImageDatabase.filter(img => {
        if (img.color.match(this.colorFilter)) return true;
      });
    },
    updateGallery: async function() {
      // instance is responsive to changes
      // change is made and forces filteredImages to do its thing
      // async await forces the browser to slow down and allows changes to take effect
      await this.$nextTick(function() {
        this.colorFilter = "Black";
      });

      await this.$nextTick(function() {
        // Doesnt hurt to zero out filters on change
        this.colorFilter = "";
      });
    }
  }
};
</script>

This is what I found while running batch files in parallel (multiple instances of the same bat file at the same time with different input parameters) :

Lets say that you have an exe file that performs a long task called LongRunningTask.exe

If you call the exe directly from the bat file, only the first call to the LongRunningTask will succed, while the rest will get an OS error "File is already in use by the process"

If you use this command:

start /B /WAIT "" "LongRunningTask.exe" "parameters"

You will be able to run multiple instances of the bat and exe, while still waiting for the task to finish before the bat continues executing the remaining commands. The /B option is to avoid creating another window, the empty quotes are needed in order to the command to work, see the reference below.

Note that if you don´t use the /WAIT in the start, the LongRunningTask will be executed at the same time than the remaining commands in the batch file, so it might create problems if one of these commands requires the output of the LongRunningTask

Resuming :

This can´t run in parallel :

• call LongRunningTask.exe

This will run in parallel and will be ok as far as there are no data dependencies between the output of the command and the rest of the bat file :

• start /B "" "LongRunningTask.exe" "parameters"

This will run in parallel and wait for the task to finish, so you can use the output :

• start /B /WAIT "" "LongRunningTask.exe" "parameters"

Reference for the start command : How can I run a program from a batch file without leaving the console open after the program start?

You can access other containers' service by their name(ping apachewill get the ip or curl http://apache would access the http service) And this can be a alternative of a static ip.

All you have to do it insert you exact db details and restart your mysql server

You can use the | operator to combine querysets directly without needing Q objects:

result = Item.objects.filter(item.creator = owner) | Item.objects.filter(item.moderated = False)

(edit - I was initially unsure if this caused an extra query but @spookylukey pointed out that lazy queryset evaluation takes care of that)

And if you have one hell of a files to download from the remote location and if you don't much care about security, try changing the scp default encryption (Triple-DES) to something like 'blowfish'.

This will reduce file copying time drastically.

scp -c blowfish -r [email protected]:/path/to/foo /home/user/Desktop/

Recently I had same issue for an error in the flex slider. The first image's height was set smaller due to the loading delay. I tried the following method for resolving that issue and it's worked.

// create image with a reference id. Id shall be used for removing it from the dom later.
var tempImg = $('<img id="testImage" />');
//If you want to get the height with respect to any specific width you set.
//I used window width here.
tempImg.css('width', window.innerWidth);  
tempImg[0].onload = function () {
    $(this).css('height', 'auto').css('display', 'none');
    var imgHeight = $(this).height();
    // Remove it if you don't want this image anymore.
    $('#testImage').remove();
}
//append to body
$('body').append(tempImg);
//Set an image url. I am using an image which I got from google.
tempImg[0].src ='http://aspo.org/wp-content/uploads/strips.jpg';

This will give you the height with respect to the width you set rather than original width or Zero.

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

You don't need to configure anything. Just make sure that the requests map to your PHP file and use requests with path info. For example, if you have in the root a file named handler.php with this content:

<?php

var_dump($_SERVER['REQUEST_METHOD']);
var_dump($_SERVER['REQUEST_URI']);
var_dump($_SERVER['PATH_INFO']);

if (($stream = fopen('php://input', "r")) !== FALSE)
    var_dump(stream_get_contents($stream));

The following HTTP request would work:

Established connection with 127.0.0.1 on port 81
PUT /handler.php/bla/foo HTTP/1.1
Host: localhost:81
Content-length: 5
 
boo
HTTP/1.1 200 OK

Content-Type: text/html
 
string(3) "PUT"
string(20) "/handler.php/bla/foo"
string(8) "/bla/foo"
string(5) "boo
"
Connection closed remotely.

You can hide the "php" extension with MultiViews or you can make URLs completely logical with mod_rewrite.

See also the documentation for the AcceptPathInfo directive and this question on how to make PHP not parse POST data when enctype is multipart/form-data.

Whenever possible I would shift all of the querying to the backend on the server (to the SQL DB or other native database type). Reason being is that it will be quicker and more optimized to do the querying.

I know that jSON can be stand alone and there may be +/- for having a querying language but I cannot see the advantage if you are retrieving data from the backend to a browser, as most of the JSON use cases. Query and filter at the backend to get as small a data that is needed.

If for whatever reason you need to query at the front-end (mostly in a browser) then I would suggest just using array.filter (why invent something else?).

That said what I think would be more useful is a transformation API for json...they are more useful since once you have the data you may want to display it in a number of ways. However, again, you can do much of this on the server (which can be much easier to scale) than on the client - IF you are using server<-->client model.

Just my 2 pence worth!

Try this:

<iframe name="iframe1" src="target.html"></iframe>

<a href="link.html" target="iframe1">link</a>

The "target" attribute should open in the iframe.

One solution to this would be a list comprehension, with pattern matching inside your tuple:

>>> mylist = [(25,7),(26,9),(55,10)]
>>> [age for (age,person_id) in mylist if person_id == 10]
[55]

Another way would be using map and filter:

>>> map( lambda (age,_): age, filter( lambda (_,person_id): person_id == 10, mylist) )
[55]

Use

.fadeOut(360).delay(400).remove();

An array doesn't have an add method. You assign a value to an element of the array with num[i]=value;.

public static void main(String[] args) {
    int[] num = new int[args.length];
    for (int i=0; i < num.length; i++){
      int neki = Integer.parseInt(args[i]);
      num[i]=neki;
    }
}

Thanks to this post, I use this style to remove the red border that appears automatically with bootstrap when a required field is displayed, but user didn't have a chance to input anything already:

input.ng-pristine.ng-invalid {
    -webkit-box-shadow: none;
    -ms-box-shadow: none;
    box-shadow:none;
}

Simple Invalidate/Restart fixed it for me. No other actions were taken

I'd like to point out that if you want to play with threads in C++, if you use cout you can get some interesting results.

Consider this code:

#include <string>
#include <iostream>
#include <thread>

using namespace std;

void task(int taskNum, string msg) {
    for (int i = 0; i < 5; ++i) {
        cout << "#" << taskNum << ": " << msg << endl;
    }
}

int main() {
    thread t1(task, 1, "AAA");
    thread t2(task, 2, "BBB");
    t1.join();
    t2.join();
    return 0;
}

// g++ ./thread.cpp -o thread.out -ansi -pedantic -pthread -std=c++0x

Now, the output comes all shuffled. It can yield different results too, try executing several times:

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

You can use printf to get it right, or you can use mutex.

#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB

Have fun!

An example with variable (ES6):

const item = document.querySelector([data-itemid="${id}"]);

If you really want a regex, you can use this one:

str.matches(".*([ \t]).*")

In the sense that everything matching this regex is not a valid xml tag name:

if(str.matches(".*([ \t]).*")) 
      print "the input string is not valid"

There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class) at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.

An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than @WebMvcTest

I've found using cmd works well as an alternative, especially when you need to pipe the output from the called application (espeically when it doesn't have built in logging, unlike msbuild)

cmd /C "$msbuild $args" >> $outputfile

You could try Davis.js, it gives you routing in your JavaScript using pushState when available and without JavaScript it allows your server side code to handle the requests.

If you're using a FormBuilder in symfony 2.7 to generate the form, you can also pass the initial data to the createFormBuilder method of the Controler

$values = array(
    'name' => "Bob"
);

$formBuilder = $this->createFormBuilder($values);
$formBuilder->add('name', 'text');

I had the same option and as soon as I turned off Instant run, it worked fine on my API16 device, but on the API24 device it worked fine with Instant run.

Hope this helps someone having the same issue

You could do:

var matchingDog = AllDogs.FirstOrDefault(dog => dog.Id == "2"));

This will return the matching dog, else it will return null.

You can then set the property like follows:

if (matchingDog != null)
    matchingDog.Name = "New Dog Name";

If performance is important, and the list usually already is sorted quite well.

Bubble sort should be one of the slowest ways of sorting, but I have seen cases where the best performance was a simple bi-directional bubble sort.

So this may be one of the few cases where you can benefit from coding it yourself. But you really need to do it right (make sure at least somebody else confirms your code, make a proof that it works etc.)

As somebody else pointed out, it may be even better to start with a sorted array, and keep it sorted while you change the contents. That may perform even better.

Update: Angular 1.1.5 added a ternary operator, so now we can simply write

<li ng-class="$first ? 'firstRow' : 'nonFirstRow'">

If you are using an earlier version of Angular, your two choices are:

1. (condition && result_if_true || !condition && result_if_false)
2. {true: 'result_if_true', false: 'result_if_false'}[condition]

item 2. above creates an object with two properties. The array syntax is used to select either the property with name true or the property with name false, and return the associated value.

E.g.,

<li class="{{{true: 'myClass1 myClass2', false: ''}[$first]}}">...</li>
 or
<li ng-class="{true: 'myClass1 myClass2', false: ''}[$first]">...</li>

$first is set to true inside an ng-repeat for the first element, so the above would apply class 'myClass1' and 'myClass2' only the first time through the loop.

With ng-class there is an easier way though: ng-class takes an expression that must evaluate to one of the following:

1. a string of space-delimited class names
2. an array of class names
3. a map/object of class names to boolean values.

An example of 1) was given above. Here is an example of 3, which I think reads much better:

 <li ng-class="{myClass: $first, anotherClass: $index == 2}">...</li>

The first time through an ng-repeat loop, class myClass is added. The 3rd time through ($index starts at 0), class anotherClass is added.

ng-style takes an expression that must evaluate to a map/object of CSS style names to CSS values. E.g.,

 <li ng-style="{true: {color: 'red'}, false: {}}[$first]">...</li>

if you wish to hide URL from the user, Show an AlertDialog as below.

myWebView.setWebChromeClient(new WebChromeClient() {

            @Override
            public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
                Log.d(TAG, "onJsAlert url: " + url + "; message: " + message);
                AlertDialog.Builder builder = new AlertDialog.Builder(
                        mContext);
                builder.setMessage(message)
                        .setNeutralButton("OK", new OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int arg1) {
                                dialog.dismiss();
                            }
                        }).show();
                result.cancel();
                return true;
            }
    }

This is the best I've found for teaching new programmers, and without using additional libraries. I'd like something better though.

def initialize_twodlist(value):
    list=[]
    for row in range(10):
        list.append([value]*10)
    return list

As an alternative to using UsedRange or providing an explicit range address, the AutoFilter.Range property can also specify the affected range.

ActiveSheet.AutoFilter.Range.Offset(1,0).Rows.SpecialCells(xlCellTypeVisible).Delete(xlShiftUp)

As used here, Offset causes the first row after the AutoFilter range to also be deleted. In order to avoid that, I would try using .Resize() after .Offset().

I know this was answered already, but I just ran into the same issue trying to specify the schema to use for the liquibase command line.

Update As of JDBC v9.4 you can specify the url with the new currentSchema parameter like so:

jdbc:postgresql://localhost:5432/mydatabase?currentSchema=myschema

Appears based on an earlier patch:

http://web.archive.org/web/20141025044151/http://postgresql.1045698.n5.nabble.com/Patch-to-allow-setting-schema-search-path-in-the-connectionURL-td2174512.html

Which proposed url's like so:

jdbc:postgresql://localhost:5432/mydatabase?searchpath=myschema

you can try this without any java script you can do that just by using CSS

img:active,
img:focus,
img:hover{ 
border: 10px solid red !important
}

of if your case is to add any other css class by clicking you can use query selector like

<img id="image1" ng-click="changeClass(id)" >
<img id="image2" ng-click="changeClass(id)" >
<img id="image3" ng-click="changeClass(id)" >
<img id="image3" ng-click="changeClass(id)" >

in controller first search for any image with red border and remove it then by passing the image id add the border class to that image

$scope.changeClass = function(id){
angular.element(document.querySelector('.some-class').removeClass('.some-class');
angular.element(document.querySelector(id)).addClass('.some-class');
}

I wrote up the answer for another question, though this is a more accurate question for it.

How do constructors and destructors work?

Here is a slightly opinionated answer.

Don't use __del__. This is not C++ or a language built for destructors. The __del__ method really should be gone in Python 3.x, though I'm sure someone will find a use case that makes sense. If you need to use __del__, be aware of the basic limitations per http://docs.python.org/reference/datamodel.html:

• __del__ is called when the garbage collector happens to be collecting the objects, not when you lose the last reference to an object and not when you execute del object.
• __del__ is responsible for calling any __del__ in a superclass, though it is not clear if this is in method resolution order (MRO) or just calling each superclass.
• Having a __del__ means that the garbage collector gives up on detecting and cleaning any cyclic links, such as losing the last reference to a linked list. You can get a list of the objects ignored from gc.garbage. You can sometimes use weak references to avoid the cycle altogether. This gets debated now and then: see http://mail.python.org/pipermail/python-ideas/2009-October/006194.html.
• The __del__ function can cheat, saving a reference to an object, and stopping the garbage collection.
• Exceptions explicitly raised in __del__ are ignored.
• __del__ complements __new__ far more than __init__. This gets confusing. See http://www.algorithm.co.il/blogs/programming/python-gotchas-1-del-is-not-the-opposite-of-init/ for an explanation and gotchas.
• __del__ is not a "well-loved" child in Python. You will notice that sys.exit() documentation does not specify if garbage is collected before exiting, and there are lots of odd issues. Calling the __del__ on globals causes odd ordering issues, e.g., http://bugs.python.org/issue5099. Should __del__ called even if the __init__ fails? See http://mail.python.org/pipermail/python-dev/2000-March/thread.html#2423 for a long thread.

But, on the other hand:

• __del__ means you do not forget to call a close statement. See http://eli.thegreenplace.net/2009/06/12/safely-using-destructors-in-python/ for a pro __del__ viewpoint. This is usually about freeing ctypes or some other special resource.

And my pesonal reason for not liking the __del__ function.

• Everytime someone brings up __del__ it devolves into thirty messages of confusion.
• It breaks these items in the Zen of Python:
  • Simple is better than complicated.
  • Special cases aren't special enough to break the rules.
  • Errors should never pass silently.
  • In the face of ambiguity, refuse the temptation to guess.
  • There should be one – and preferably only one – obvious way to do it.
  • If the implementation is hard to explain, it's a bad idea.

So, find a reason not to use __del__.

Keep it simple, silly! ;)

Simple OR logic...

Add the below css as per you want your screen width.

I found that this is the most jQuery way, IMHO. Extending the default function is easy and can be done in a global extension file.

$.fn.exist = function(){
  return !!this.length;
};

console.log($("#yes").exist())

console.log($("#no").exist())

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div id="yes">id = yes</div>

You copy and paste the following code. It will display all the tables with Name and Created Date

SELECT object_name,created FROM user_objects
WHERE object_name LIKE  '%table_name%'
AND object_type = 'TABLE'; 

Note: Replace '%table_name%' with the table name you are looking for.

You could try

(whatever) | while read line; do echo $line | head --bytes -3; done;

head itself should be faster than sed or cut because there's no regex or delimeter matching, but invoking a for every line separately would probably outweigh that.

You should really import the module into its own alias.

import datetime as dt
my_datetime = dt.datetime(year, month, day)

The above has the following benefits over the other solutions:

• Calling the variable my_datetime instead of date reduces confusion since there is already a date in the datetime module (datetime.date).
• The module and the class (both called datetime) do not shadow each other.

There is at least one middleware on npm for handling CORS in Express: cors. [see @mscdex answer]

This is how to set custom response headers, from the ExpressJS DOC

res.set(field, [value])

Set header field to value

res.set('Content-Type', 'text/plain');

or pass an object to set multiple fields at once.

res.set({
  'Content-Type': 'text/plain',
  'Content-Length': '123',
  'ETag': '12345'
})

Aliased as

res.header(field, [value])

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

More efficient and easy way to print the 2D array in a formatted way:

Try this:

public static void print(int[][] puzzle) {
        for (int[] row : puzzle) {
            for (int elem : row) {
                System.out.printf("%4d", elem);
            }
            System.out.println();
        }
        System.out.println();
    }

Sample Output:

   0   1   2   3
   4   5   6   7
   8   9  10  11
  12  13  14  15

Considering this still shows up when we search for EF in .NET Core, I'll post my answer here (Since it has haunted me a lot). Note that there are some subtleties with the EF 6 .NET version (No initial command, and you will need to delete "Snapshot" files)

(Tested in .NET Core 2.1)

Here are the steps:

1. Delete the _efmigrationhistory table.
2. Search for your entire solution for files that contain Snapshot in their name, such as ApplicationDbContextSnapshot.cs, and delete them.
3. Rebuild your solution
4. Run Add-Migration InitialMigration

Please note: You must delete ALL the Snapshot files. I spent countless hours just deleting the database... This will generate an empty migration if you don't do it.

Also, in #3 you can just name your migration however you want.

Here are some additional resources: asp.net CORE Migrations generated empty

Reset Entity Framework 7 migrations

the percent should be relative to an absolute size, try this :

table {
  width:200px;
}

td {
  width:65%;
  border:1px solid black;
}

<table>
  <tr>
    <td>Testasdas 3123 1 dasd as da</td>
    <td>A long string blah blah blah</td>
  </tr>
</table>
    

Check the following link: How to pretty-print XML (Unfortunately, the link now returns 404 :()

The method in the link takes an XML string as an argument and returns a well-formed (indented) XML string.

I just copied the sample code from the link to make this answer more comprehensive and convenient.

public static String PrettyPrint(String XML)
{
    String Result = "";

    MemoryStream MS = new MemoryStream();
    XmlTextWriter W = new XmlTextWriter(MS, Encoding.Unicode);
    XmlDocument D   = new XmlDocument();

    try
    {
        // Load the XmlDocument with the XML.
        D.LoadXml(XML);

        W.Formatting = Formatting.Indented;

        // Write the XML into a formatting XmlTextWriter
        D.WriteContentTo(W);
        W.Flush();
        MS.Flush();

        // Have to rewind the MemoryStream in order to read
        // its contents.
        MS.Position = 0;

        // Read MemoryStream contents into a StreamReader.
        StreamReader SR = new StreamReader(MS);

        // Extract the text from the StreamReader.
        String FormattedXML = SR.ReadToEnd();

        Result = FormattedXML;
    }
    catch (XmlException)
    {
    }

    MS.Close();
    W.Close();

    return Result;
}

You can use Stopwatch

import com.google.common.base.Stopwatch;

Stopwatch timer = Stopwatch.createStarted();
//lines to be executed
System.out.println("Execution time= " + timer.stop());

It's possible that the HTML5 Doctype is causing you problems with those older browsers. It could also be down to something funky related to the HTML5 shiv.

You could try switching to one of the XHTML doctypes and changing your markup accordingly, at least temporarily. This might allow you to narrow the problem down.

Is your design breaking when those IEs switch to quirks mode? If it's your CSS causing things to display strangely, it might be worth working on the CSS so the site looks the same even when the browsers switch modes.

Less happened to me, I just want to change (a word or character) in the String

So I've use the Dictionary

  extension String{
    func replace(_ dictionary: [String: String]) -> String{
          var result = String()
          var i = -1
          for (of , with): (String, String)in dictionary{
              i += 1
              if i<1{
                  result = self.replacingOccurrences(of: of, with: with)
              }else{
                  result = result.replacingOccurrences(of: of, with: with)
              }
          }
        return result
     }
    }

usage

let mobile = "+1 (800) 444-9999"
let dictionary = ["+": "00", " ": "", "(": "", ")": "", "-": ""]
let mobileResult = mobile.replace(dictionary)
print(mobileResult) // 001800444999

You need to drag the EditText from the edge of the layout and not just the other widget. You can also add constraints by just dragging the constraint point that surrounds the widget to the edge of the screen to add constraints as specified.

The modified code will look something similar to this:

    app:layout_constraintLeft_toLeftOf="@+id/router_text"
    app:layout_constraintTop_toTopOf="@+id/activity_main"
    android:layout_marginTop="320dp"
    app:layout_constraintBottom_toBottomOf="@+id/activity_main"
    android:layout_marginBottom="16dp"
    app:layout_constraintVertical_bias="0.29" 

Use geom_text , with aes label. You can play with hjust, vjust to adjust text position.

ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +geom_text(aes(label=Name),hjust=0, vjust=0)

EDIT: Label only values above a certain threshold:

  ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +
  geom_text(aes(label=ifelse(PTS>24,as.character(Name),'')),hjust=0,vjust=0)

You can checkout remote branch /n git fetch && git checkout remotebranch

You can simple make use of lapply or sapply builtin functions.

lapply will return you a list -

lapply(dataframe,class)

while sapply will take the best possible return type ex. Vector etc -

sapply(dataframe,class)

Both the commands will return you all the column names with their respective class.

webpack is not only in your node-modules/webpack/bin/ directory, it's also linked in node_modules/.bin.

You have the npm bin command to get the folder where npm will install executables.

You can use the scripts property of your package.json to use webpack from this directory which will be exported.

"scripts": {
  "scriptName": "webpack --config etc..."
}

For example:

"scripts": {
  "build": "webpack --config webpack.config.js"
}

You can then run it with:

npm run build

Or even with arguments:

npm run build -- <args>

This allow you to have you webpack.config.js in the root folder of your project without having webpack globally installed or having your webpack configuration in the node_modules folder.

I would suggest the use of MySQLi or MySQL PDO for performance and security purposes, but to answer the question:

while($row = mysql_fetch_assoc($result)){
     $json[] = $row;
}

echo json_encode($json);

If you switched to MySQLi you could do:

$query = "SELECT * FROM table";
$result = mysqli_query($db, $query);

$json = mysqli_fetch_all ($result, MYSQLI_ASSOC);
echo json_encode($json );

This limit is indeed not specified, however their TOS mentions that: "FOR EXAMPLE, WE DON’T MAKE ANY COMMITMENTS ABOUT THE CONTENT WITHIN THE SERVICES, THE SPECIFIC FUNCTIONS OF THE SERVICES, OR THEIR RELIABILITY, AVAILABILITY, OR ABILITY TO MEET YOUR NEEDS. WE PROVIDE THE SERVICES “AS IS”. "

This means to me that the download limit is calculated based on a set of factors that describe the user and is subject to change from one to another.

Maybe using the TOR network may help you do your job.

Try this.For swift.

func checkCardValidation(number : String) -> Bool
{
    let reversedInts = number.characters.reversed().map { Int(String($0)) }
        return reversedInts.enumerated().reduce(0, {(sum, val) in
            let odd = val.offset % 2 == 1
            return sum + (odd ? (val.element! == 9 ? 9 : (val.element! * 2) % 9) : val.element!)
        }) % 10 == 0
}

Use.

if (self.checkCardValidation(number: "yourNumber") == true) {
     print("Card Number valid")
}else{
     print("Card Number not valid")
}

"exit" is an event that gets triggered when node finish it's event loop internally, it's not triggered when you terminate the process externally.

What you're looking for is executing something on a SIGINT.

The docs at http://nodejs.org/api/process.html#process_signal_events give an example:

Example of listening for SIGINT:

// Start reading from stdin so we don't exit.
process.stdin.resume();

process.on('SIGINT', function () {
  console.log('Got SIGINT.  Press Control-D to exit.');
});

Note: this seems to interrupt the sigint and you would need to call process.exit() when you finish with your code.

I just wanted to add to the great Flexbox solution described by Pavlo, that, in my case, I had two lists/columns of data that I wanted to display side-by-side with just a little spacing between, horizontally-centered inside an enclosing div. By nesting another div within the first (leftmost) flex:1 div and floating it right, I got just what I wanted. I couldn't find any other way to do this with consistent success at all viewport widths:

<div style="display:flex">
    <div style="flex:1;padding-right:15px">
        <div style="float:right">
            [My Left-hand list of stuff]
        </div>
    </div>

    <div style="flex:1;padding-left:15px">
            [My Right-hand list of stuff]
    </div>
</div>

If you only need the dynamic properties for JSON serialization/deserialization, eg if your API accepts a JSON object with different fields depending on context, then you can use the JsonExtensionData attribute available in Newtonsoft.Json or System.Text.Json.

Example:

public class Pet
{
    public string Name { get; set; }
    public string Type { get; set; }

    [JsonExtensionData]
    public IDictionary<string, object> AdditionalData { get; set; }
}

Then you can deserialize JSON:

public class Program
{
    public static void Main()
    {
        var bingo = JsonConvert.DeserializeObject<Pet>("{\"Name\": \"Bingo\", \"Type\": \"Dog\", \"Legs\": 4 }");
        Console.WriteLine(bingo.AdditionalData["Legs"]);        // 4

        var tweety = JsonConvert.DeserializeObject<Pet>("{\"Name\": \"Tweety Pie\", \"Type\": \"Bird\", \"CanFly\": true }");
        Console.WriteLine(tweety.AdditionalData["CanFly"]);     // True

        tweety.AdditionalData["Color"] = "#ffff00";

        Console.WriteLine(JsonConvert.SerializeObject(tweety)); // {"Name":"Tweety Pie","Type":"Bird","CanFly":true,"Color":"#ffff00"}
    }
}

Your and should be a && in the where clause.

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
and epl.ArriveAirportBy > sd.UTCArrivalTime

should be

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
&& epl.ArriveAirportBy > sd.UTCArrivalTime

A one-liner solution, similar to python, would be (std::set<int> {1, 2, 3, 4}).count(my_var) > 0.

Minimal working example

int my_var = 3;
bool myVarIn = (std::set<int> {1, 2, 3, 4}).count(my_var) > 0;
std::cout << std::boolalpha << myVarIn << std::endl;

prints true or false dependent of the value of my_var.

I think this is what you are looking for? If you are looking to add a blur effect to a div element, you can do this directly through CSS Filters-- See fiddle: http://jsfiddle.net/ayhj9vb0/

 div {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  width: 100px;
  height: 100px;
  background-color: #ccc;

}

If you are debugging or similar - In chrome developer tools, you can simply use

$x('/html/.//div[@id="text"]')

You can also use the following code:

<?php
$filename = $_GET["nama"];
$contenttype = "application/force-download";
header("Content-Type: " . $contenttype);
header("Content-Disposition: attachment; filename=\"" . basename($filename) . "\";");
readfile("your file uploaded path".$filename);
exit();
?>

You can try:

int sum = startingNumber; 
for (int i=0; i < positiveInteger; i++) {     
    sum += i;
}
cout << sum;

But much easier is to note that the sum 1+2+...+n = n*(n+1) / 2, so you do not need a loop at all, just use the formula n*(n+1)/2.

for php version 5.2.17 __DIR__ will not work it will only works with php 5.3

But for older version of php dirname(__FILE__) perfectly

For example write like this

require_once dirname(__FILE__) . '/db_config.php';

I'm currently experimenting with canvas and pixels... I'm finding this logic works out for me better.

1. Use this to calculate the grey-ness ( luma ? )
2. but with both the existing value and the new 'tint' value
3. calculate the difference ( I found I did not need to multiply )

4. add to offset the 'tint' value

   var grey =  (r + g + b) / 3;    
   var grey2 = (new_r + new_g + new_b) / 3;
   
   var dr =  grey - grey2 * 1;    
   var dg =  grey - grey2 * 1    
   var db =  grey - grey2 * 1;  
   
   tint_r = new_r + dr;    
   tint_g = new_g + dg;   
   tint_b = new_b _ db;
   

or something like that...

One trick I use to tell if X is running is:

telnet 127.0.0.1 6000

If it connects, you have an X server running and its accepting inbound TCP connections (not usually the default these days)....

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

This is a very old question, but I do not feel that the benefits of ASMX have been fairly portrayed. While not terribly flexible, ASMX web services are very simple to use and understand. While WCF is more flexible, it is also more complex to stand up and configure.

ASMX web services are ready to stand up and add as a webservice reference as soon as you add the file. (assuming your project builds)

For the simple development workflow of create webservice -> run webservice -> add webservice reference, an ASMX webservice has very little that can go wrong, not much that you can misconfigure, and that is it's strength.

In response to those that assert that WCF replaces ASMX, I would reply that WCF would need to add a streamlined K.I.S.S. configuration mode in order to completely replace ASMX.

Example web.config for an ASMX webservice:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings />
  <system.web>
    <compilation targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>
</configuration>

This solution worked for me. Try this, add following lines in your app's build.gradle file

splits {
    abi {
        enable true
        reset()
        include 'x86', 'armeabi-v7a'
        universalApk true
    }
}

The DictWriter() class expects dictionaries for each row. If all you wanted to do was write an initial header, use a regular csv.writer() and pass in a simple row for the header:

import csv

with open('combined_file.csv', 'w', newline='') as outcsv:
    writer = csv.writer(outcsv)
    writer.writerow(["Date", "temperature 1", "Temperature 2"])

    with open('t1.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows(row + [0.0] for row in reader)

    with open('t2.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows(row[:1] + [0.0] + row[1:] for row in reader)

The alternative would be to generate dictionaries when copying across your data:

import csv

with open('combined_file.csv', 'w', newline='') as outcsv:
    writer = csv.DictWriter(outcsv, fieldnames = ["Date", "temperature 1", "Temperature 2"])
    writer.writeheader()

    with open('t1.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows({'Date': row[0], 'temperature 1': row[1], 'temperature 2': 0.0} for row in reader)

    with open('t2.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows({'Date': row[0], 'temperature 1': 0.0, 'temperature 2': row[1]} for row in reader)

Another option is using the overloaded + operator:

>>> l = ['hello','world']
>>> l = ['foo'] + l
>>> l
['foo', 'hello', 'world']

In your pg_hba.conf file, I see some incorrect and confusing lines:

# fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32
# not recommend because of the lax permissions
host    all        all         192.168.0.1/32        trust

# wrong, /128 is an invalid netmask for ipv4, this line should be removed
host    all        all         192.168.0.1/128       trust

# this conflicts with the first line
# it says that that the password should be md5 and not plaintext
# I think the first line should be removed
host    all        all         192.168.0.1/32        md5

# this is fine except is it unnecessary because of the previous line
# which allows any user and any database to connect with md5 password
host    chaosLRdb  postgres    192.168.0.1/32        md5

# wrong, on local lines, an IP cannot be specified
# remove the 4th column
local   all        all         192.168.0.1/32        trust

I suspect that if you md5'd the password, this might work if you trim the lines. To get the md5 you can use perl or the following shell script:

 echo -n 'chaos123' | md5sum
 > d6766c33ba6cf0bb249b37151b068f10  -

So then your connect line would like something like:

my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433",
    "chaosuser", "d6766c33ba6cf0bb249b37151b068f10");

For more information, here's the documentation of postgres 8.X's pg_hba.conf file.

Other (undocumented) way to do it, is to call:

$("form").validate().cancelSubmit = true;

on the click event of the button (for example).

The following MySQL statement should modify your column to accept NULLs.

ALTER TABLE `MyTable`
ALTER COLUMN `Col3` varchar(20) DEFAULT NULL

To change the integrated terminal on Windows, you just need to change the terminal.integrated.shell.windows line:

1. Open VS User Settings (Preferences > User Settings). This will open two side-by-side documents.
2. Add a new "terminal.integrated.shell.windows": "C:\\Bin\\Cmder\\Cmder.exe" setting to the User Settings document on the right if it's not already there. This is so you aren't editing the Default Setting directly, but instead adding to it.
3. Save the User Settings file.

You can then access it with keys Ctrl+backtick by default.

You can use the command pkill to kill processes. If you want to "play around", you can use "pgrep", which works exactly the same but returns the process rather than killing it.

pkill has the -f parameter that allows you to match against the entire command. So for your example, you can: pkill -f "gedit file.txt"

table.test td {
    background-color: lime;
    padding: 12px;
    border:2px solid #fff;border-collapse:separate;
}

First we grab the command output, then wrap it and select one of its properties. There is only one and its "Name" which is what we want. So we select the groups property with ".name" then output it.

to text file

 (Get-ADGroupMember 'Domain Admins' |Select name).name | out-file Admins1.txt

to csv

(Get-ADGroupMember 'Domain Admins' |Select name).name | export-csv -notypeinformation "Admins1.csv"

Use this to get an admin window with either bash or cmd running, from any directories context menue. Just right click on a directory name, and select the entry or hit the highlited button.

This is based on the chere tool and the unfortunately not working answer (for me) from link_boy. It works fine for me using Windows 8,

A side effect is the different color in the admin cmd window. To use this on bash, you can change the .bashrc file of the admin user.

I coudln't get the "background" version (right click into an open directory) to run. Feel free to add it.

Node.js is an open source command line tool built for the server side JavaScript code. You can download a tarball, compile and install the source. It lets you run JavaScript programs.

The JavaScript is executed by the V8, a JavaScript engine developed by Google which is used in Chrome browser. It uses a JavaScript API to access the network and file system.

It is popular for its performance and the ability to perform parallel operations.

Understanding node.js is the best explanation of node.js I have found so far.

Following are some good articles on the topic.

Hit enter as there is no password. Enter the following commands:

mysql> SET PASSWORD for 'root'@'localhost' = password('enteryourpassword');
mysql> SET PASSWORD for 'root'@'127.0.0.1' = password('enteryourpassword');
mysql> SET PASSWORD for 'root'@'::1' = password('enteryourpassword');

That’s it, I keep the passwords the same to keep things simple. If you want to check the user’s table to see that the info has been updated just enter the additional commands as shown below. This is a good option to check that you have indeed entered the same password for all hosts.

In python 3.1 you can produce a list in a way

     lst=list(range(100))
     for i in range(100)
        print (lst[i],',',end='')

In python 2.7 you can do it as

     lst=range(100)
     for i in range(100)
        print lst[i]+',' 

After reading @MLProgrammer-CiM's answer, here is my code:

class NormalViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

    @Bind(R.id.card_item_normal)
    CardView cardView;

    public NormalViewHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this, itemView);
        cardView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if(v instanceof CardView) {
            // use getAdapterPosition() instead of getLayoutPosition()
            int itemPosition = getAdapterPosition();
            removeItem(itemPosition);
        }
    }
}

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

Re-posted as an answer: Found an alternative (Tested in Win8):

cmdkey /generic:"<server>" /user:"<user>" /pass:"<pass>"

Run that and if you run:

mstsc /v:<server>

You should not get an authentication prompt.

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

You can use Object.assign() to merge them into a new object:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = Object.assign({}, item, { location: response });_x000D_
_x000D_
console.log(newItem );

You can also use object spread, which is a Stage 4 proposal for ECMAScript:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = { ...item, location: response }; // or { ...response } if you want to clone response as well_x000D_
_x000D_
console.log(newItem );

Without knowing your compiler, no one can give you specific, step by step instructions, but the basic procedure is as follows:

1. Specify the path which should be searched in order to find the actual library (usually under Library Search Paths, Library Directories, etc. in the properties page)

2. Under linker options, specify the actual name of the library. In VS, you would write Allegro.lib (or whatever it is), on Linux you usually just write Allegro (prefixes/suffixes are added automatically in most cases). This is usually under "Libraries->Input", just "Libraries", or something similar.

3. Ensure that you have included the headers for the library and make sure that they can be found (similar process to that listed in step #1 and #2). If it is a static library, you should be good; if it's a DLL, you need to copy it in your project.

4. Mash the build button.

A solution without using "eval":

var setInnerHtml = function(elm, html) {
  elm.innerHTML = html;
  var scripts = elm.getElementsByTagName("script");
  // If we don't clone the results then "scripts"
  // will actually update live as we insert the new
  // tags, and we'll get caught in an endless loop
  var scriptsClone = [];
  for (var i = 0; i < scripts.length; i++) {
    scriptsClone.push(scripts[i]);
  }
  for (var i = 0; i < scriptsClone.length; i++) {
    var currentScript = scriptsClone[i];
    var s = document.createElement("script");
    // Copy all the attributes from the original script
    for (var j = 0; j < currentScript.attributes.length; j++) {
      var a = currentScript.attributes[j];
      s.setAttribute(a.name, a.value);
    }
    s.appendChild(document.createTextNode(currentScript.innerHTML));
    currentScript.parentNode.replaceChild(s, currentScript);
  }
}

This essentially clones the script tag and then replaces the blocked script tag with the newly generated one, thus allowing execution.

Yes, you need to make getInstance() synchronized. If it's not there might arise a situation where multiple instances of the class can be made.

Consider the case where you have two threads that call getInstance() at the same time. Now imagine T1 executes just past the instance == null check, and then T2 runs. At this point in time the instance is not created or set, so T2 will pass the check and create the instance. Now imagine that execution switches back to T1. Now the singleton is created, but T1 has already done the check! It will proceed to make the object again! Making getInstance() synchronized prevents this problem.

There a few ways to make singletons thread-safe, but making getInstance() synchronized is probably the simplest.

Have you also tried following, it should work:

sudo chown <username> /dev/kvm
sudo chmod o+x /dev/kvm

You have code that is compliled into some IL (intermediate language). When you run your program, the computer doesn't understand this code. It only understands native code. So the JIT compiler compiles your IL into native code on the fly. It does this at the method level.

I generally use array split because it's easier simple syntax and scales better with more than 2 partitions.

import numpy as np
partitions = 2
dfs = np.array_split(df, partitions)

np.split(df, [100,200,300], axis=0] wants explicit index numbers which may or may not be desirable.

brew -v or brew --version does the trick!

__file__ is absolute since Python 3.4, except when executing a script directly using a relative path:

Module __file__ attributes (and related values) should now always contain absolute paths by default, with the sole exception of __main__.__file__ when a script has been executed directly using a relative path. (Contributed by Brett Cannon in bpo-18416.)

Not sure if it resolves symlinks though.

Example of passing a relative path:

$ python script.py

Use nested inline if-then statements (Ternary Operators)

<div ng-class=" ... ? 'class-1' : ( ... ? 'class-2' : 'class-3')">

for example :

<div ng-class="apt.name.length >= 15 ? 'col-md-12' : (apt.name.length >= 10 ? 'col-md-6' : 'col-md-4')">
    ...
</div>

And make sure it's readable by your colleagues :)

You can convert it to char* if you don't need a modifiable string by using:

(char*) yourString.c_str();

This would be very useful when you want to publish a String variable via MQTT in arduino.

You can try with this code

Image.Save("myfile.png", ImageFormat.Png)

Link : http://msdn.microsoft.com/en-us/library/ms142147.aspx

the following will do:

date -d "$(date +%Y-%m-1) -1 month" +%-m
date -d "$(date +%Y-%m-1) 0 month" +%-m
date -d "$(date +%Y-%m-1) 1 month" +%-m

or as you need:

LAST_MONTH=`date -d "$(date +%Y-%m-1) -1 month" +%-m`
NEXT_MONTH=`date -d "$(date +%Y-%m-1) 1 month" +%-m`
THIS_MONTH=`date -d "$(date +%Y-%m-1) 0 month" +%-m`

you asked for output like 9,10,11, so I used the %-m

%m (without -) will produce output like 09,... (leading zero)

this also works for more/less than 12 months:

date -d "$(date +%Y-%m-1) -13 month" +%-m

just try

date -d "$(date +%Y-%m-1) -13 month"

• groupByKey() is just to group your dataset based on a key. It will result in data shuffling when RDD is not already partitioned.
• reduceByKey() is something like grouping + aggregation. We can say reduceBykey() equvelent to dataset.group(...).reduce(...). It will shuffle less data unlike groupByKey().
• aggregateByKey() is logically same as reduceByKey() but it lets you return result in different type. In another words, it lets you have a input as type x and aggregate result as type y. For example (1,2),(1,4) as input and (1,"six") as output. It also takes zero-value that will be applied at the beginning of each key.

Note : One similarity is they all are wide operations.

export class ClassName extends Component{
      constructor(props){
        super(props);
        this.state = {
          id:parseInt(props.match.params.id,10)
        }
    }
     render(){
        return(
          //Code
          {this.state.id}
        );
}

For those, like me, who did not have the possibility to use angular directive and were "stuck" outside of the angular scope, here is something that might help you.

After hours searching on the web and on the angular doc, I have created a class that compiles HTML, place it inside a targets, and binds it to a scope ($rootScope if there is no $scope for that element)

/**
 * AngularHelper : Contains methods that help using angular without being in the scope of an angular controller or directive
 */
var AngularHelper = (function () {
    var AngularHelper = function () { };

    /**
     * ApplicationName : Default application name for the helper
     */
    var defaultApplicationName = "myApplicationName";

    /**
     * Compile : Compile html with the rootScope of an application
     *  and replace the content of a target element with the compiled html
     * @$targetDom : The dom in which the compiled html should be placed
     * @htmlToCompile : The html to compile using angular
     * @applicationName : (Optionnal) The name of the application (use the default one if empty)
     */
    AngularHelper.Compile = function ($targetDom, htmlToCompile, applicationName) {
        var $injector = angular.injector(["ng", applicationName || defaultApplicationName]);

        $injector.invoke(["$compile", "$rootScope", function ($compile, $rootScope) {
            //Get the scope of the target, use the rootScope if it does not exists
            var $scope = $targetDom.html(htmlToCompile).scope();
            $compile($targetDom)($scope || $rootScope);
            $rootScope.$digest();
        }]);
    }

    return AngularHelper;
})();

It covered all of my cases, but if you find something that I should add to it, feel free to comment or edit.

Hope it will help.

Okay so someone is probably going to slap me for this answer, but I use jQuery to solve all my irritating problems and it turns out that I just used something today to fix a similar issue. Assuming you use jquery:

$("#content").sibling("#backgroundContainer").css("height",$("#content").outerHeight());

this is untested but I think you can see the concept here. Basically after it is loaded, you can get the height (outerHeight includes padding + borders, innerHeight for the content only). Hope that helps.

Here is how you bind it to the window resize event:

$(window).resize(function() {
  $("#content").sibling("#backgroundContainer").css("height",$("#content").outerHeight());
});

The numerical value seems to be missing from your price definition. Try the following:

<xs:simpleType name="curr">
  <xs:restriction base="xs:string">
    <xs:enumeration value="pounds" />
    <xs:enumeration value="euros" />
    <xs:enumeration value="dollars" />
  </xs:restriction>
</xs:simpleType>



<xs:element name="price">
        <xs:complexType>
            <xs:extension base="xs:decimal">
              <xs:attribute name="currency" type="curr"/>
            </xs:extension>
        </xs:complexType>
</xs:element>

You may want to add

HttpURLConnection.setFollowRedirects(false);
// note : or
//        huc.setInstanceFollowRedirects(false)

if you don't want to follow redirection (3XX)

Instead of doing a "GET", a "HEAD" is all you need.

huc.setRequestMethod("HEAD");
return (huc.getResponseCode() == HttpURLConnection.HTTP_OK);

Haha, oh boy, I figured it out. Somehow, someway, I did not install the Database Engine when I installed SQL Server 2008. I have no idea how I missed that, but that's what happened.

For iOS 13+

in SceneDelegate:

var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options 
connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = (scene as? UIWindowScene) else { return }
    window = UIWindow(windowScene: windowScene)
    let storyboard = UIStoryboard(name: "Main", bundle: nil) // Where "Main" is the storyboard file name
    let vc = storyboard.instantiateViewController(withIdentifier: "ViewController") // Where "ViewController" is the ID of your viewController
    window?.rootViewController = vc
    window?.makeKeyAndVisible()
}

If you want to do something AFTER the rotation is complete, you can use the UIViewControllerTransitionCoordinator completion handler like this

public override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    // Hook in to the rotation animation completion handler
    coordinator.animate(alongsideTransition: nil) { (_) in
        // Updates to your UI...
        self.tableView.reloadData()
    }
}

select * from 
(
    select top 2 t2.ID
    from Table t2
    where t2.Type = 'TYPE_2'
    order by t2.ReceivedDate desc
) t2

or using CTE (SQL Server 2005+)

;with One as
(
    select top 2 t1.ID, t1.ReceivedDate
    from Table t1
    where t1.Type = 'TYPE_1'
    order by t1.ReceivedDate de

,Two as

    select top 2 t2.ID

)
select * from One
union

I know this is an old question but if you're still programming, in python 3 these days... I have actually found that if it is a string, then there is a really easy way to do this:

>>> spam.upper
<built-in method upper of str object at 0x1042e4830>
>>> spam.upper()
'YO I NEED HELP!'
>>> id(spam)
4365109296

string conversion does not affect location in memory either:

>>> spam = {437 : 'passphrase'}
>>> object.__repr__(spam)
'<dict object at 0x1043313f0>'
>>> str(spam)
"{437: 'passphrase'}"
>>> object.__repr__(spam)
'<dict object at 0x1043313f0>'

The ANSI escape sequences you're looking for are the Select Graphic Rendition subset. All of these have the form

\033[XXXm

where XXX is a series of semicolon-separated parameters.

To say, make text red, bold, and underlined (we'll discuss many other options below) in C you might write:

printf("\033[31;1;4mHello\033[0m");

In C++ you'd use

std::cout<<"\033[31;1;4mHello\033[0m";

In Python3 you'd use

print("\033[31;1;4mHello\033[0m")

and in Bash you'd use

echo -e "\033[31;1;4mHello\033[0m"

where the first part makes the text red (31), bold (1), underlined (4) and the last part clears all this (0).

As described in the table below, there are a large number of text properties you can set, such as boldness, font, underlining, &c. (Isn't it silly that StackOverflow doesn't allow you to put proper tables in answers?)

4-bit Colours

The standards implementing terminal colours began with limited (4-bit) options. The table below lists the RGB values of the background and foreground colours used for these by a variety of terminal emulators:

Using the above, you can make red text on a green background (but why?) using:

11 Colours (An Interlude)

In their book "Basic Color Terms: Their Universality and Evolution", Brent Berlin and Paul Kay used data collected from twenty different languages from a range of language families to identify eleven possible basic color categories: white, black, red, green, yellow, blue, brown, purple, pink, orange, and gray.

Berlin and Kay found that, in languages with fewer than the maximum eleven color categories, the colors followed a specific evolutionary pattern. This pattern is as follows:

1. All languages contain terms for black (cool colours) and white (bright colours).
2. If a language contains three terms, then it contains a term for red.
3. If a language contains four terms, then it contains a term for either green or yellow (but not both).
4. If a language contains five terms, then it contains terms for both green and yellow.
5. If a language contains six terms, then it contains a term for blue.
6. If a language contains seven terms, then it contains a term for brown.
7. If a language contains eight or more terms, then it contains terms for purple, pink, orange or gray.

This may be why story Beowulf only contains the colours black, white, and red. It may also be why the Bible does not contain the colour blue. Homer's Odyssey contains black almost 200 times and white about 100 times. Red appears 15 times, while yellow and green appear only 10 times. (More information here)

Differences between languages are also interesting: note the profusion of distinct colour words used by English vs. Chinese. However, digging deeper into these languages shows that each uses colour in distinct ways. (More information)

Generally speaking, the naming, use, and grouping of colours in human languages is fascinating. Now, back to the show.

8-bit (256) colours

Technology advanced, and tables of 256 pre-selected colours became available, as shown below.

Using these above, you can make pink text like so:

\033[38;5;206m     #That is, \033[38;5;<FG COLOR>m

And make an early-morning blue background using

\033[48;5;57m      #That is, \033[48;5;<BG COLOR>m

And, of course, you can combine these:

\033[38;5;206;48;5;57m

The 8-bit colours are arranged like so:

0x00-0x07:  standard colors (same as the 4-bit colours)
0x08-0x0F:  high intensity colors
0x10-0xE7:  6 × 6 × 6 cube (216 colors): 16 + 36 × r + 6 × g + b (0 = r, g, b = 5)
0xE8-0xFF:  grayscale from black to white in 24 steps

ALL THE COLOURS

Now we are living in the future, and the full RGB spectrum is available using:

\033[38;2;<r>;<g>;<b>m     #Select RGB foreground color
\033[48;2;<r>;<g>;<b>m     #Select RGB background color

So you can put pinkish text on a brownish background using

\033[38;2;255;82;197;48;2;155;106;0mHello

Support for "true color" terminals is listed here.

Much of the above is drawn from the Wikipedia page "ANSI escape code".

A Handy Script to Remind Yourself

Since I'm often in the position of trying to remember what colours are what, I have a handy script called: ~/bin/ansi_colours:

#!/usr/bin/python

print "\\033[XXm"

for i in range(30,37+1):
    print "\033[%dm%d\t\t\033[%dm%d" % (i,i,i+60,i+60);

print "\033[39m\\033[39m - Reset colour"
print "\\033[2K - Clear Line"
print "\\033[<L>;<C>H OR \\033[<L>;<C>f puts the cursor at line L and column C."
print "\\033[<N>A Move the cursor up N lines"
print "\\033[<N>B Move the cursor down N lines"
print "\\033[<N>C Move the cursor forward N columns"
print "\\033[<N>D Move the cursor backward N columns"
print "\\033[2J Clear the screen, move to (0,0)"
print "\\033[K Erase to end of line"
print "\\033[s Save cursor position"
print "\\033[u Restore cursor position"
print " "
print "\\033[4m  Underline on"
print "\\033[24m Underline off"
print "\\033[1m  Bold on"
print "\\033[21m Bold off"

This prints

If you are using navigation components and navigation graph create a bundle like this

val bundle = bundleOf(KEY to VALUE) // or whatever you would like to create the bundle

then when navigating to the other fragment use this:

findNavController().navigate(
        R.id.action_navigate_from_frag1_to_frag2,
        bundle
    )

and when you land the destination fragment u can access that bundle using

Bundle b = getArguments()// in Java

or

val b = arguments// in kotlin

Calendar.getInstance().get(Calendar.MONTH);

is zero based, 10 is November. From the javadoc;

public static final int MONTH Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

Calendar.getInstance().get(Calendar.JANUARY);

is not a sensible thing to do, the value for JANUARY is 0, which is the same as ERA, you are effectively calling;

Calendar.getInstance().get(Calendar.ERA);

$('#cloneDiv').click(function(){


  // get the last DIV which ID starts with ^= "klon"
  var $div = $('div[id^="klon"]:last');

  // Read the Number from that DIV's ID (i.e: 3 from "klon3")
  // And increment that number by 1
  var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;

  // Clone it and assign the new ID (i.e: from num 4 to ID "klon4")
  var $klon = $div.clone().prop('id', 'klon'+num );

  // Finally insert $klon wherever you want
  $div.after( $klon.text('klon'+num) );

});

I'm assuming you're using Linq-to-SQL* (see note below). If so, use string.Contains, string.StartsWith, and string.EndsWith to generate SQL that use the SQL LIKE operator.

from o in dc.Organization
join oh in dc.OrganizationsHierarchy on o.Id equals oh.OrganizationsId
where oh.Hierarchy.Contains(@"/12/")
select new { o.Id, o.Name }

or

from o in dc.Organization
where o.OrganizationsHierarchy.Hierarchy.Contains(@"/12/")
select new { o.Id, o.Name }

Note: * = if you are using the ADO.Net Entity Framework (EF / L2E) in .net 3.5, be aware that it will not do the same translation as Linq-to-SQL. Although L2S does a proper translation, L2E v1 (3.5) will translate into a t-sql expression that will force a full table scan on the table you're querying unless there is another better discriminator in your where clause or join filters.
Update: This is fixed in EF/L2E v4 (.net 4.0), so it will generate a SQL LIKE just like L2S does.

Alternatively you can use Jetty which is (now) part of the Eclipe Platform (the Help system is running Jetty). Besides Jetty is used by Android, Windows Mobile..
