This is a better method :-

void main()throws IOException
{
    System.out.println("Enter sentence");
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String str = br.readLine();
    String sentence = "";
    for(int i=0;i<str.length();i++)
    {
        if(Character.isUpperCase(str.charAt(i))==true)
        {
            char ch2= (char)(str.charAt(i)+32);
            sentence = sentence + ch2;
        }
        else if(Character.isLowerCase(str.charAt(i))==true)
        {
            char ch2= (char)(str.charAt(i)-32);
            sentence = sentence + ch2;
        }
        else
        sentence= sentence + str.charAt(i);

    }
    System.out.println(sentence);
}

Use String#toLowerCase() or String#equalsIgnoreCase() methods

Some examples:

    String abc    = "Abc".toLowerCase();
    boolean isAbc = "Abc".equalsIgnoreCase("ABC");

Don't try this, totally un-recommend, don't do this:

import string
s='ABCD'
print(''.join([string.ascii_lowercase[string.ascii_uppercase.index(i)] for i in s]))

Output:

abcd

Since no one wrote it yet you can use swapcase (so uppercase letters will become lowercase, and vice versa) (and this one you should use in cases where i just mentioned (convert upper to lower, lower to upper)):

s='ABCD'
print(s.swapcase())

Output:

abcd

If you want to only update on rows that are not currently uppercase (instead of all rows), you'd need to identify the difference using COLLATE like this:

UPDATE MyTable
SET    MyColumn = UPPER(MyColumn)
WHERE  MyColumn != UPPER(MyColumn) COLLATE Latin1_General_CS_AS 

A Bit About Collation

Cases sensitivity is based on your collation settings, and is typically case insensitive by default.

Collation can be set at the Server, Database, Column, or Query Level:

-- Server
SELECT SERVERPROPERTY('COLLATION')
-- Database
SELECT name, collation_name FROM sys.databases
-- Column 
SELECT COLUMN_NAME, COLLATION_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE CHARACTER_SET_NAME IS NOT NULL

Collation Names specify how a string should be encoded and read, for example:

• Latin1_General_CI_AS ? Case Insensitive
• Latin1_General_CS_AS ? Case Sensitive

The .swapcase method transforms the uppercase latters in a string to lowercase and the lowercase letters to uppercase.

'TESTING'.swapcase #=> testing
'testing'.swapcase #=> TESTING

Why not execute in backticks ?

 x=`echo "$y" | tr '[:upper:]' '[:lower:]'` 

This assigns the result of the command in backticks to the variable x. (i.e. it's not particular to tr but is a common pattern/solution for shell scripting)

You can use $(..) instead of the backticks. See here for more info.

This may not be what you are looking for but I thought you oughta know the real way to do this. You can use the java.lang.Character class's isUpperCase() to find aout about the case of the character. You can use isDigit() to differentiate between the numbers and letters(This is just FYI :) ). You can then do a toUpperCase() and then do the switch for vowels. This will improve your code quality.

I think you are trying to capitalize first and last character of each word in a sentence with space as delimiter.

Can be done through StringBuffer:

public static String toFirstLastCharUpperAll(String string){
    StringBuffer sb=new StringBuffer(string);
        for(int i=0;i<sb.length();i++)
            if(i==0 || sb.charAt(i-1)==' ' //for first character of string/each word
                || i==sb.length()-1 || sb.charAt(i+1)==' ') //for last character of string/each word
                sb.setCharAt(i, Character.toUpperCase(sb.charAt(i)));
     return sb.toString();
}

Here ya go:

viewNoteDateMonth.text  = [[displayDate objectAtIndex:2] uppercaseString];

Btw:
"april" is lowercase ? [NSString lowercaseString]
"APRIL" is UPPERCASE ? [NSString uppercaseString]
"April May" is Capitalized/Word Caps ? [NSString capitalizedString]
"April may" is Sentence caps ? (method missing; see workaround below)

Hence what you want is called "uppercase", not "capitalized". ;)

As for "Sentence Caps" one has to keep in mind that usually "Sentence" means "entire string". If you wish for real sentences use the second method, below, otherwise the first:

@interface NSString ()

- (NSString *)sentenceCapitalizedString; // sentence == entire string
- (NSString *)realSentenceCapitalizedString; // sentence == real sentences

@end

@implementation NSString

- (NSString *)sentenceCapitalizedString {
    if (![self length]) {
        return [NSString string];
    }
    NSString *uppercase = [[self substringToIndex:1] uppercaseString];
    NSString *lowercase = [[self substringFromIndex:1] lowercaseString];
    return [uppercase stringByAppendingString:lowercase];
}

- (NSString *)realSentenceCapitalizedString {
    __block NSMutableString *mutableSelf = [NSMutableString stringWithString:self];
    [self enumerateSubstringsInRange:NSMakeRange(0, [self length])
                             options:NSStringEnumerationBySentences
                          usingBlock:^(NSString *sentence, NSRange sentenceRange, NSRange enclosingRange, BOOL *stop) {
        [mutableSelf replaceCharactersInRange:sentenceRange withString:[sentence sentenceCapitalizedString]];
    }];
    return [NSString stringWithString:mutableSelf]; // or just return mutableSelf.
}

@end

Here's a UDF that will do the trick...

create function ProperCase(@Text as varchar(8000))
returns varchar(8000)
as
begin
  declare @Reset bit;
  declare @Ret varchar(8000);
  declare @i int;
  declare @c char(1);

  if @Text is null
    return null;

  select @Reset = 1, @i = 1, @Ret = '';

  while (@i <= len(@Text))
    select @c = substring(@Text, @i, 1),
      @Ret = @Ret + case when @Reset = 1 then UPPER(@c) else LOWER(@c) end,
      @Reset = case when @c like '[a-zA-Z]' then 0 else 1 end,
      @i = @i + 1
  return @Ret
end

You will still have to use it to update your data though.

a nicer way

app.filter('capitalize', function() {
  return function(token) {
      return token.charAt(0).toUpperCase() + token.slice(1);
   }
});

From the dplyr package you can also use the mutate_all() function in combination with toupper(). This will affect both character and factor classes.

library(dplyr)
df <- mutate_all(df, funs=toupper)

  <telerik:RadTextBox ID="txtCityName" runat="server" MaxLength="50" Width="200px"
                            Style="text-transform: uppercase;">

For questions on simple string manipulation the dir built-in function comes in handy. It gives you, among others, a list of methods of the argument, e.g., dir(s) returns a list containing upper.

With this simple code:

String example="hello";

example=example.substring(0,1).toUpperCase()+example.substring(1, example.length());

System.out.println(example);

Result: Hello

Don't do things like [A-Z] or [0-9]. Do \p{Lu} and \d instead. Of course, this is valid for perl based regex flavours. This includes java.

I would suggest that you don't make some huge regex. First split the text in sentences. then tokenize it (split into words). Use a regex to check each token/word. Skip the first token from sentence. Check if all tokens are uppercase beforehand and skip the whole sentence if so, or alter the regex in this case.

You can use LOWER function and UPPER function. Like

SELECT LOWER('THIS IS TEST STRING')

Result:

this is test string

And

SELECT UPPER('this is test string')

result:

THIS IS TEST STRING

Use input filter

editText = (EditText) findViewById(R.id.enteredText);
editText.setFilters(new InputFilter[]{new InputFilter.AllCaps()});

use a maxlength attribute to your input.

<input type="text" id="phone" name="phone" maxlength="10">

See the fiddle demo here Demo

string cannot be the parameter to Nullable because string is not a value type. String is a reference type.

string s = null; 

is a very valid statement and there is not need to make it nullable.

private string typeOfContract
    {
      get { return ViewState["typeOfContract"] as string; }
      set { ViewState["typeOfContract"] = value; }
    }

should work because of the as keyword.

undefined index means that somewhere in the $_POST array, there isn't an index (key) for the key username.

You should be setting your posted values into variables for a more clean solution, and it's a good habit to get into.

If I was having a similar error, I'd do something like this:

$username = $_POST['username']; // you should really do some more logic to see if it's set first
echo $username;

If username didn't turn up, that'd mean I was screwing up somewhere. You can also,

var_dump($_POST);

To see what you're posting. var_dump is really useful as far as debugging. Check it out: var_dump

Though this is an old post, please consider using @NamedEntityGraph (Javax Persistence) and @EntityGraph (Spring Data JPA). The combination works.

Example

@Entity
@Table(name = "Employee", schema = "dbo", catalog = "ARCHO")
@NamedEntityGraph(name = "employeeAuthorities",
            attributeNodes = @NamedAttributeNode("employeeGroups"))
public class EmployeeEntity implements Serializable, UserDetails {
// your props
}

and then the spring repo as below

@RepositoryRestResource(collectionResourceRel = "Employee", path = "Employee")
public interface IEmployeeRepository extends PagingAndSortingRepository<EmployeeEntity, String>           {

    @EntityGraph(value = "employeeAuthorities", type = EntityGraphType.LOAD)
    EmployeeEntity getByUsername(String userName);

}

Typing /** + then pressing Enter above a method signature will create Javadoc stubs for you.

We're getting errors about duplicate configuration directives on the one of our apps. After investigation it looks like it's because of this issue.

In brief, our root website is ASP.NET 3.5 (which is 2.0 with specific libraries added), and we have a subapplication that is ASP.NET 4.0.

web.config inheritance causes the ASP.NET 4.0 sub-application to inherit the web.config file of the parent ASP.NET 3.5 application.

However, the ASP.NET 4.0 application's global (or "root") web.config, which resides at C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config and C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config (depending on your bitness), already contains these config sections.

The ASP.NET 4.0 app then tries to merge together the root ASP.NET 4.0 web.config, and the parent web.config (the one for an ASP.NET 3.5 app), and runs into duplicates in the node.

The only solution I've been able to find is to remove the config sections from the parent web.config, and then either

1. Determine that you didn't need them in your root application, or if you do
2. Upgrade the parent app to ASP.NET 4.0 (so it gains access to the root web.config's configSections)

You have another process that’s listening on port 8080 which is the default port that’s used by Spring Boot’s web support. You either need to stop that process or configure your app to listen on another port.

You can change the port configuration by adding server.port=4040 (for example) to src/main/resources/application.properties

Got same issue and it turns out that besides setting PATH variable, I also should not close some cmd window poped up during installation. Re-installation would work

you can use this for example

$array = json_decode($string,true)

but validate the Json before. You can validate from http://jsonviewer.stack.hu/

In my case, double quotes was not a problem.

Last comma gave me same error message.

{'a':{'b':c,}}
           ^

To remove this comma, I wrote some simple code.

import json

with open('a.json','r') as f:
    s = f.read()
    s = s.replace('\t','')
    s = s.replace('\n','')
    s = s.replace(',}','}')
    s = s.replace(',]',']')
    data = json.loads(s)

And this worked for me.

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

Both Chrome and Firefox now have built-in emulators. They aren't perfect but are good enough that can get you almost all of the way before testing on an actual device. The best part is if you like the browser's developer tools (Chrome, Firefox), you can use them while emulating.

To get the emulator: [Ctrl+Shift+M] and select the device that you want to emulate. You might have to refresh the page, esp if you have anything that depends on script that executes on page load.

Internet Explorer also has a device emulation mode. F12, then CTRL+8. It's not quite as straight forward as the Chrome Mobile Device emulation, but does allow you to simulate geolocation:

1. set a rule to check the file name (if the form is multipart)

   $this->form_validation->set_rules('upload_file[name]', 'Upload file', 'required', 'No upload image :(');

2. overwrite the $_POST array as follows:

   $_POST['upload_file'] = $_FILES['upload_file']

3. and then do:

   $this->form_validation->run()

Edit

To address comments that this answer doesn't directly address the original question. If you got here from a Google Search, start here

There is a function available called override_function that actually fits the bill. However, given that this function is part of The Advanced PHP Debugger extension, it's hard to make an argument that override_function() is intended for production use. Therefore, I would say "No", it is not possible to overwrite a function with the intent that the original questioner had in mind.

Original Answer

This is where you should take advantage of OOP, specifically polymorphism.

interface Fooable
{
    public function ihatefooexamples();
}

class Foo implements Fooable
{
    public function ihatefooexamples()
    {
        return "boo-foo!";
    }
}

class FooBar implements Fooable
{
    public function ihatefooexamples()
    {
        return "really boo-foo";
    }
}

$foo = new Foo();

if (10 == $_GET['foolevel']) {
    $foo = new FooBar();
}

echo $foo->ihatefooexamples();

I am bit late to the part. Just like to suggest another way.

  button.calendar::before {
    content: '\f073';
    font-family: 'Font Awesome 5 Free';
    left: -4px;
    bottom: 4px;
    position: relative;
  }

position,left and bottom is used to align icon.

Sometimes adding font-weight 600 or above also helps.

I got the same problem when accessing mysql with root. The problem I found is that some database files does not have permission by the mysql user, which is the user that started the mysql server daemon.

We can check this with ls -l /var/lib/mysql command, if the mysql user does not have permission of reading or writing on some files or directories, that might cause problem. We can change the owner or mode of those files or directories with chown/chmod commands.

After these changes, restart the mysqld daemon and login with root with command:

mysql -u root

Then change passwords or create other users for logging into mysql.

In Android Studio go to File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle

(if on mac) Android Studio -> preferences... -> Build, Execution, Deployment -> Build Tools -> Gradle

Check the 'Offline work' under 'Global Gradle settings'

Note: In newer version of Android studio, View->Tool Windows->Gradle->Toggle button of online/offline

It will reduce 90% gradle build time.

if you just added a new dependency in your gradle you will have to uncheck the offline work or gradle will not be able to resolve the dependencies. After the complete resolving then you you can check the offline work for a faster build

Atomic collections are accessible by $

Recursive collections are not. Rather the [[ ]] is used

 Browse[1]> is.atomic(list())
 [1] FALSE

 Browse[1]> is.atomic(data.frame())
 [1] FALSE

 Browse[1]> is.atomic(class(list(foo="bar")))
 [1] TRUE

 Browse[1]> is.atomic(c(" lang "))
 [1] TRUE

R can be funny sometimes

 a = list(1,2,3)
 b = data.frame(a)
 d = rbind("?",c(b))
 e = exp(1)
 f = list(d)
 print(data.frame(c(list(f,e))))

I would recommend using the visual designer built into VS2008, as updating the dbml also updates the code that is generated for you. Modifying the dbml outside of the visual designer would result in the underlying code being out of sync.

I had this problem before, and the reason is very simple: Check your variables, if there were strings, so put it in quotes '$your_string_variable_here' ,, if it were numerical keep it without any quotes. for example, if I had these data: $name ( It will be string ) $phone_number ( It will be numerical ) So, it will be like that:

$query = "INSERT INTO users (name, phone) VALUES ('$name', $phone)"; Just like that and it will be fixed ^_^

#include <unistd.h>
#include <termios.h>

char getch(void)

    char buf = 0;
    struct termios old = {0};
    fflush(stdout);
    if(tcgetattr(0, &old) < 0)
        perror("tcsetattr()");
    old.c_lflag &= ~ICANON;
    old.c_lflag &= ~ECHO;
    old.c_cc[VMIN] = 1;
    old.c_cc[VTIME] = 0;
    if(tcsetattr(0, TCSANOW, &old) < 0)
        perror("tcsetattr ICANON");
    if(read(0, &buf, 1) < 0)
        perror("read()");
    old.c_lflag |= ICANON;
    old.c_lflag |= ECHO;
    if(tcsetattr(0, TCSADRAIN, &old) < 0)
        perror("tcsetattr ~ICANON");
    printf("%c\n", buf);
    return buf;
 }

Remove the last printf if you don't want the character to be displayed.

SQL> select substr('999123456789', greatest (-9, -length('999123456789')), 9) as value from dual;

VALUE
---------
123456789

SQL> select substr('12345', greatest (-9,  -length('12345')), 9) as value from dual;

VALUE

12345

The call to greatest (-9, -length(string)) limits the starting offset either 9 characters left of the end or the beginning of the string.

If you're really, absolutely positively sure that the NSURL is a file url, i.e. [url isFileURL] is guaranteed to return true in your case, then you can simply use:

Actions vs Transformations

• Collect (Action) - Return all the elements of the dataset as an array at the driver program. This is usually useful after a filter or other operation that returns a sufficiently small subset of the data.

spark-sql doc

select(*cols) (transformation) - Projects a set of expressions and returns a new DataFrame.

Parameters: cols – list of column names (string) or expressions (Column). If one of the column names is ‘*’, that column is expanded to include all columns in the current DataFrame.**

df.select('*').collect()
[Row(age=2, name=u'Alice'), Row(age=5, name=u'Bob')]
df.select('name', 'age').collect()
[Row(name=u'Alice', age=2), Row(name=u'Bob', age=5)]
df.select(df.name, (df.age + 10).alias('age')).collect()
[Row(name=u'Alice', age=12), Row(name=u'Bob', age=15)]

Execution select(column-name1,column-name2,etc) method on a dataframe, returns a new dataframe which holds only the columns which were selected in the select() function.

e.g. assuming df has several columns including "name" and "value" and some others.

df2 = df.select("name","value")

df2 will hold only two columns ("name" and "value") out of the entire columns of df

df2 as the result of select will be in the executors and not in the driver (as in the case of using collect())

sql-programming-guide

df.printSchema()
# root
# |-- age: long (nullable = true)
# |-- name: string (nullable = true)

# Select only the "name" column
df.select("name").show()
# +-------+
# |   name|
# +-------+
# |Michael|
# |   Andy|
# | Justin|
# +-------+

You can running collect() on a dataframe (spark docs)

>>> l = [('Alice', 1)]
>>> spark.createDataFrame(l).collect()
[Row(_1=u'Alice', _2=1)]
>>> spark.createDataFrame(l, ['name', 'age']).collect()
[Row(name=u'Alice', age=1)]

spark docs

To print all elements on the driver, one can use the collect() method to first bring the RDD to the driver node thus: rdd.collect().foreach(println). This can cause the driver to run out of memory, though, because collect() fetches the entire RDD to a single machine; if you only need to print a few elements of the RDD, a safer approach is to use the take(): rdd.take(100).foreach(println).

Its depend. If you have more than two images in .column but you only need some images to have css applied then its better to add class to image directly instead of doing .column img{/*styling for image here*/}

In performance aspect i thing apply class to image is better because by doing so css will not look for possible child image.

I found a solution:

print("My message here");

If your TextView create click issues, than remove android:inputType="" from your xml file.

To get it to work with Apache, we needed one extra step.

openssl pkcs12 -in domain.pfx -clcerts -nokeys -out domain.cer
openssl pkcs12 -in domain.pfx -nocerts -nodes  -out domain_encrypted.key
openssl rsa -in domain_encrypted.key -out domain.key

The final command decrypts the key for use with Apache. The domain.key file should look like this:

You can create a bitmap transfer. try this....

In the first class:

1) Create:

private static Bitmap bitmap_transfer;

2) Create getter and setter

public static Bitmap getBitmap_transfer() {
    return bitmap_transfer;
}

public static void setBitmap_transfer(Bitmap bitmap_transfer_param) {
    bitmap_transfer = bitmap_transfer_param;
}

3) Set the image:

ImageView image = (ImageView) view.findViewById(R.id.image);
image.buildDrawingCache();
setBitmap_transfer(image.getDrawingCache());

Then, in the second class:

ImageView image2 = (ImageView) view.findViewById(R.id.img2);
imagem2.setImageDrawable(new BitmapDrawable(getResources(), classe1.getBitmap_transfer()));

It will work.

You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

Disclosure : I’m a developer of funfun

For me, an expression like

if (typeof query !== 'undefined' && query !== null){
   // do stuff
}

is more complicated than I want for how often I want to use it. That is, testing if a variable is defined/null is something I do frequently. I want such a test to be simple. To resolve this, I first tried to define the above code as a function, but node just gives me a syntax error, telling me the parameter to the function call is undefined. Not useful! So, searching about and working on this bit, I found a solution. Not for everyone perhaps. My solution involves using Sweet.js to define a macro. Here's how I did it:

Here's the macro (filename: macro.sjs):

// I had to install sweet using:
// npm install --save-dev
// See: https://www.npmjs.com/package/sweetbuild
// Followed instructions from https://github.com/mozilla/sweet.js/wiki/node-loader

// Initially I just had "($x)" in the macro below. But this failed to match with 
// expressions such as "self.x. Adding the :expr qualifier cures things. See
// http://jlongster.com/Writing-Your-First-Sweet.js-Macro

macro isDefined {
  rule {
    ($x:expr)
  } => {
    (( typeof ($x) === 'undefined' || ($x) === null) ? false : true)
  }
}


// Seems the macros have to be exported
// https://github.com/mozilla/sweet.js/wiki/modules

export isDefined;

Here's an example of usage of the macro (in example.sjs):

function Foobar() {
    var self = this;

    self.x = 10;

    console.log(isDefined(y)); // false
    console.log(isDefined(self.x)); // true
}

module.exports = Foobar;

And here's the main node file:

var sweet = require('sweet.js');

// load all exported macros in `macros.sjs`
sweet.loadMacro('./macro.sjs');

// example.sjs uses macros that have been defined and exported in `macros.sjs`
var Foobar = require('./example.sjs');

var x = new Foobar();

A downside of this, aside from having to install Sweet, setup the macro, and load Sweet in your code, is that it can complicate error reporting in Node. It adds a second layer of parsing. Haven't worked with this much yet, so shall see how it goes first hand. I like Sweet though and I miss macros so will try to stick with it!

Use

Model.created_at.strftime("%FT%T")

where,

%F - The ISO 8601 date format (%Y-%m-%d)
%T - 24-hour time (%H:%M:%S)

Following are some of the frequently used useful list of Date and Time formats that you could specify in strftime method:

Date (Year, Month, Day):
  %Y - Year with century (can be negative, 4 digits at least)
          -0001, 0000, 1995, 2009, 14292, etc.
  %C - year / 100 (round down.  20 in 2009)
  %y - year % 100 (00..99)

  %m - Month of the year, zero-padded (01..12)
          %_m  blank-padded ( 1..12)
          %-m  no-padded (1..12)
  %B - The full month name (``January'')
          %^B  uppercased (``JANUARY'')
  %b - The abbreviated month name (``Jan'')
          %^b  uppercased (``JAN'')
  %h - Equivalent to %b

  %d - Day of the month, zero-padded (01..31)
          %-d  no-padded (1..31)
  %e - Day of the month, blank-padded ( 1..31)

  %j - Day of the year (001..366)

Time (Hour, Minute, Second, Subsecond):
  %H - Hour of the day, 24-hour clock, zero-padded (00..23)
  %k - Hour of the day, 24-hour clock, blank-padded ( 0..23)
  %I - Hour of the day, 12-hour clock, zero-padded (01..12)
  %l - Hour of the day, 12-hour clock, blank-padded ( 1..12)
  %P - Meridian indicator, lowercase (``am'' or ``pm'')
  %p - Meridian indicator, uppercase (``AM'' or ``PM'')

  %M - Minute of the hour (00..59)

  %S - Second of the minute (00..59)

  %L - Millisecond of the second (000..999)
  %N - Fractional seconds digits, default is 9 digits (nanosecond)
          %3N  millisecond (3 digits)
          %6N  microsecond (6 digits)
          %9N  nanosecond (9 digits)
          %12N picosecond (12 digits)

System.Decimal implements the IConvertable interface, which has a ToInt32() member.

Does calling System.Decimal.ToInt32() work for you?

Here is something that's pretty interesting. Although exit() and die() are equivalent, die() closes the connection. exit() doesn't close the connection.

die():

<?php
    header('HTTP/1.1 304 Not Modified');
    die();
?>

exit():

<?php
    header('HTTP/1.1 304 Not Modified');
    exit();
?>

Results:

exit():

HTTP/1.1 304 Not Modified 
Connection: Keep-Alive 
Keep-Alive: timeout=5, max=100

die():

HTTP/1.1 304 Not Modified 
Connection: close

Just incase in need to take this into account for your project.

I measured it's performance in a loop of 200 runs against the code that uses the AttributeValuesMultiString recursive method; and it worked 1.3 times faster. It might be so because of our AD settings. Both snippets gave the same result though.

The recommended way is to create your own component, such as MyAppText. MyAppText would be a simple component that renders a Text component using your universal style and can pass through other props, etc.

It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!

The only times you should need to escape are when trying to put " inside a string, or ' in a character:

String quotes = "He said \"Hello, World!\"";
char quote = '\'';

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

Possibly browser returns String representation of some integer value? Actually int can't be null. May be you could check for null, if value is not null, then transform String representation to int.

TL;DR ...and late to the party, but that short explanation might help future googlers..

In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.

A minimal example:

df <- data.frame(a = 1:2); df$a <- 1:3

throws the error

Error in $<-.data.frame(*tmp*, a, value = 1:3) : replacement has 3 rows, data has 2

which is clear, because the vector a of df has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).

Generate a protected application for Mac or Windows from your Excel spreadsheet using OfficeProtect with either AppProtect or QuickLicense/AddLicense. There is a demonstation video called "Protect Excel Spreedsheet" at www.excelsoftware.com/videos.

The VS equivalent of a makefile is a "Solution" (over-simplified, I know).

        e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";
        e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.gvbind, "Select$" + e.Row.RowIndex);

Sounds like you are using Microsoft Visual C++. If that is the case, then the most possibility is that you don't compile your two.cpp with one.cpp (one.cpp is the implementation for one.h).

If you are from command line (cmd.exe), then try this first: cl -o two.exe one.cpp two.cpp

If you are from IDE, right click on the project name from Solution Explore. Then choose Add, Existing Item.... Add one.cpp into your project.

SQLite has limited ALTER TABLE support that you can use to add a column to the end of a table or to change the name of a table.

If you want to make more complex changes in the structure of a table, you will have to recreate the table. You can save existing data to a temporary table, drop the old table, create the new table, then copy the data back in from the temporary table.

For example, suppose you have a table named "t1" with columns names "a" and "c" and that you want to insert column "b" from this table. The following steps illustrate how this could be done:

BEGIN TRANSACTION;
CREATE TEMPORARY TABLE t1_backup(a,c);
INSERT INTO t1_backup SELECT a,c FROM t1;
DROP TABLE t1;
CREATE TABLE t1(a,b, c);
INSERT INTO t1 SELECT a,c FROM t1_backup;
DROP TABLE t1_backup;
COMMIT;

Now you are ready to insert your new data like so:

UPDATE t1 SET b='blah' WHERE a='key'

std::copy is what you're looking for.

if danday74's fix doesn't work, check that the parent element has a height.

In my case I had two childs, one floating left and one floating right. I wanted the right floating one to become sticky but had to add a <div style="clear: both;"></div> at the end of the parent, to give it height.

How are you loading this page? Is it getting anything on POST to load? If it's not, then the $name = $_POST['Name']; assignation doesn't have any 'Name' on POST.

Turns out Visual Studio was being dumb, as the problem was related to the backup files I had made of my aspx.cs class. I deleted those and the errors went away.

It can convert by

Convert.ToInt32 method

But it will throw an OverflowException if it the value is outside range of the Int32 Type. A basic test will show us how it works:

long[] numbers = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue };
int result;
foreach (long number in numbers)
{
   try {
         result = Convert.ToInt32(number);
        Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                    number.GetType().Name, number,
                    result.GetType().Name, result);
     }
     catch (OverflowException) {
      Console.WriteLine("The {0} value {1} is outside the range of the Int32 type.",
                    number.GetType().Name, number);
     }
}
// The example displays the following output:
//    The Int64 value -9223372036854775808 is outside the range of the Int32 type.
//    Converted the Int64 value -1 to the Int32 value -1.
//    Converted the Int64 value 0 to the Int32 value 0.
//    Converted the Int64 value 121 to the Int32 value 121.
//    Converted the Int64 value 340 to the Int32 value 340.
//    The Int64 value 9223372036854775807 is outside the range of the Int32 type.

Here there is a longer explanation.

You are building a DataGridView on the fly and set the DataSource for it. That's good, but then do you add the DataGridView to the Controls collection of the hosting form?

this.Controls.Add(dataGridView1);

By the way the code is a bit confused

String connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\\Tables.accdb;Persist Security Info=True";
string sql  = "SELECT Clients  FROM Tables";
using(OleDbConnection conn = new OleDbConnection(connection))
{
     conn.Open();
     DataSet ds = new DataSet();
     DataGridView dataGridView1 = new DataGridView();
     using(OleDbDataAdapter adapter = new OleDbDataAdapter(sql,conn))
     {
         adapter.Fill(ds);
         dataGridView1.DataSource = ds;
         // Of course, before addint the datagrid to the hosting form you need to 
         // set position, location and other useful properties. 
         // Why don't you create the DataGrid with the designer and use that instance instead?
         this.Controls.Add(dataGridView1);
     }
}

EDIT After the comments below it is clear that there is a bit of confusion between the file name (TABLES.ACCDB) and the name of the table CLIENTS.
The SELECT statement is defined (in its basic form) as

 SELECT field_names_list FROM _tablename_

so the correct syntax to use for retrieving all the clients data is

 string sql  = "SELECT * FROM Clients";

where the * means -> all the fields present in the table

Google did quietly enable offline recognition in that Search update, but there is (as yet) no API or additional parameters available within the SpeechRecognizer class. {See Edit at the bottom of this post} The functionality is available with no additional coding, however the user’s device will need to be configured correctly for it to begin working and this is where the problem lies and I would imagine why a lot of developers assume they are ‘missing something’.

Also, Google have restricted certain Jelly Bean devices from using the offline recognition due to hardware constraints. Which devices this applies to is not documented, in fact, nothing is documented, so configuring the capabilities for the user has proved to be a matter of trial and error (for them). It works for some straight away – For those that it doesn't, this is the ‘guide’ I supply them with.

1. Make sure the default Android Voice Recogniser is set to Google not Samsung/Vlingo
2. Uninstall any offline recognition files you already have installed from the Google Voice Search Settings
3. Go to your Android Application Settings and see if you can uninstall the updates for the Google Search and Google Voice Search applications.
4. If you can't do the above, go to the Play Store see if you have the option there.
5. Reboot (if you achieved 2, 3 or 4)
6. Update Google Search and Google Voice Search from the Play Store (if you achieved 3 or 4 or if an update is available anyway).
7. Reboot (if you achieved 6)
8. Install English UK offline language files
9. Reboot
10. Use utter! with a connection
11. Switch to aeroplane mode and give it a try
12. Once it is working, the offline recognition of other languages, such as English US should start working too.

EDIT: Temporarily changing the device locale to English UK also seems to kickstart this to work for some.

Some users reported they still had to reboot a number of times before it would begin working, but they all get there eventually, often inexplicably to what was the trigger, the key to which are inside the Google Search APK, so not in the public domain or part of AOSP.

From what I can establish, Google tests the availability of a connection prior to deciding whether to use offline or online recognition. If a connection is available initially but is lost prior to the response, Google will supply a connection error, it won’t fall-back to offline. As a side note, if a request for the network synthesised voice has been made, there is no error supplied it if fails – You get silence.

The Google Search update enabled no additional features in Google Now and in fact if you try to use it with no internet connection, it will error. I mention this as I wondered if the ability would be withdrawn as quietly as it appeared and therefore shouldn't be relied upon in production.

If you intend to start using the SpeechRecognizer class, be warned, there is a pretty major bug associated with it, which require your own implementation to handle.

Not being able to specifically request offline = true, makes controlling this feature impossible without manipulating the data connection. Rubbish. You’ll get hundreds of user emails asking you why you haven’t enabled something so simple!

EDIT: Since API level 23 a new parameter has been added EXTRA_PREFER_OFFLINE which the Google recognition service does appear to adhere to.

Hope the above helps.

The exception message says you're trying to connect to the same host (127.0.0.1), while you're stating that your server is running on a different host. Besides the obvious bugs like having "localhost" in the url, or maybe some you might want to check your DNS settings.

The code of the accepted answer works for most cases, but to get a button that really behaves like a link you need a bit more code. It is especially tricky to get the styling of focused buttons right on Firefox (Mozilla).

The following CSS ensures that anchors and buttons have the same CSS properties and behave the same on all common browsers:

button {
  align-items: normal;
  background-color: rgba(0,0,0,0);
  border-color: rgb(0, 0, 238);
  border-style: none;
  box-sizing: content-box;
  color: rgb(0, 0, 238); 
  cursor: pointer;
  display: inline;
  font: inherit;
  height: auto;
  padding: 0;
  perspective-origin: 0 0;
  text-align: start;
  text-decoration: underline;
  transform-origin: 0 0;
  width: auto;
  -moz-appearance: none;
  -webkit-logical-height: 1em; /* Chrome ignores auto, so we have to use this hack to set the correct height  */
  -webkit-logical-width: auto; /* Chrome ignores auto, but here for completeness */
}

/* Mozilla uses a pseudo-element to show focus on buttons, */
/* but anchors are highlighted via the focus pseudo-class. */

@supports (-moz-appearance:none) { /* Mozilla-only */
  button::-moz-focus-inner { /* reset any predefined properties */ 
    border: none;
    padding: 0;
  }
  button:focus { /* add outline to focus pseudo-class */
    outline-style: dotted;
    outline-width: 1px;
  }
}

The example above only modifies button elements to improve readability, but it can easily be extended to modify input[type="button"], input[type="submit"] and input[type="reset"] elements as well. You could also use a class, if you want to make only certain buttons look like anchors.

See this JSFiddle for a live-demo.

Please also note that this applies the default anchor-styling to buttons (e.g. blue text-color). So if you want to change the text-color or anything else of anchors & buttons, you should do this after the CSS above.

getAttribute() -> It fetches the text that contains one of any attribute in the HTML tag. Suppose there is an HTML tag like

<input name="Name Locator" value="selenium">Hello</input>

Now getAttribute() fetches the data of the attribute of 'value', which is "Selenium".

Returns:

The attribute's current value or null if the value is not set.

driver.findElement(By.name("Name Locator")).getAttribute("value")  //

The field value is retrieved by the getAttribute("value") Selenium WebDriver predefined method and assigned to the String object.

getText() -> delivers the innerText of a WebElement. Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.

Returns:

The innerText of this element.

driver.findElement(By.name("Name Locator")).getText();

'Hello' will appear

Issue Description:

1. You want your ClassA to have a ClassB class variable.
2. You are using Objective-C as programming language.
3. Objective-C does not support class variables as C++ does.

One Alternative:

Simulate a class variable behavior using Objective-C features

1. Declare/Define an static variable within the classA.m so it will be only accessible for the classA methods (and everything you put inside classA.m).

2. Overwrite the NSObject initialize class method to initialize just once the static variable with an instance of ClassB.

3. You will be wondering, why should I overwrite the NSObject initialize method. Apple documentation about this method has the answer: "The runtime sends initialize to each class in a program exactly one time just before the class, or any class that inherits from it, is sent its first message from within the program. (Thus the method may never be invoked if the class is not used.)".

4. Feel free to use the static variable within any ClassA class/instance method.

Code sample:

file: classA.m

static ClassB *classVariableName = nil;

@implementation ClassA

...
 
+(void) initialize
{
    if (! classVariableName)
        classVariableName = [[ClassB alloc] init];
}

+(void) classMethodName
{
    [classVariableName doSomething]; 
}

-(void) instanceMethodName
{
    [classVariableName doSomething]; 
}

...

@end

Maybe this answer helps:

mysql5.58 unstart server in mac os 10.6.5

I just installed MySQL 5.5.8 (mysql-5.5.8-osx10.6-x86_64.dmg) on Mac os X 10.6.5 and also had the problem that MySQL was not starting.

After reading this post: http://forums.mysql.com/read.php?11,399397,399606#msg-399606 and editing the file as suggested everything started working.

I also did

sudo chown -R root:wheel /Library/StartupItems/MySQLCOM

after reading https://discussions.apple.com/message/12820394 since when restarting my Mac OSx 10.6.6 it kept on asking something about not enough privileges. The line above solved that issue.

Now everything is working.

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

list.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

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

        }
    });

You can call the function from code behind like this :

MyForm.aspx.cs

protected void MyButton_Click(object sender, EventArgs e)
{
    Page.ClientScript.RegisterStartupScript(this.GetType(), "myScript", "AnotherFunction();", true);
}

MyForm.aspx

    function Test() {
        alert("hi");
        $("#ButtonRow").show();
    }
    function AnotherFunction()
    {
        alert("This is another function");
    }
</script>
</head>

            </asp:RadioButtonList>
        </td>
    </tr>
    <tr id="ButtonRow"style="display:none">

    </tr>

Redis. Let’s say you’ve written a site in php; for whatever reason, it becomes popular and it’s ahead of its time or has porno on it. You realize this php is so freaking slow, "I’m gonna lose my fans because they simply won’t wait 10 seconds for a page." You have a sudden realization that a web page has a constant url (it never changes, whoa), a primary key if you will, and then you recall that memory is fast while disk is slow and php is even slower. :( Then you fashion a storage mechanism using memory and this URL that you call a "key" while the webpage content you decide to call the "value." That’s all you have - key and content. You call it "meme cache." You like Richard Dawkins because he's awesome. You cache your html like squirrels cache their nuts. You don’t need to rewrite your crap php code. You are happy. Then you see that others have done it -- but you choose Redis because the other one has confusing images of cats, some with fangs.

Mongo. You’ve written a site. Heck you’ve written many, and in any language. You realize that much of your time is spent writing those stinking SQL clauses. You’re not a dba, yet there you are, writing stupid sql statements... not just one but freaking everywhere. "select this, select that". But in particular you remember the irritating WHERE clause. Where lastname equals "thornton" and movie equals "bad santa." Urgh. You think, "why don’t those dbas just do their job and give me some stored procedures?" Then you forget some minor field like middlename and then you have to drop the table, export all 10G of big data and create another with this new field, and import the data -- and that goes on 10 times during the next 14 days as you keep on remembering crap like salutation, title, plus adding a foreign key with addresses. Then you figure that lastname should be lastName. Almost one change a day. Then you say darnit. I have to get on and write a web site/system, never mind this data model bs. So you google, "I hate writing SQL, please no SQL, make it stop" but up pops 'nosql' and then you read some stuff and it says it just dumps data without any schema. You remember last week's fiasco dropping more tables and smile. Then you choose mongo because some big guys like 'airbud' the apt rental site uses it. Sweet. No more data model changes because you have a model you just keep on changing.

How to set the python version back to 2.7 if you have installed Anaconda3 (Python 3.6) on MacOS High Sierra 10.13.5

Edit the .bash_profile file in your home directory.

vi $HOME/.bash_profile

hash out the line # export PATH="/Users/YOURUSERNAME/anaconda3/bin:$PATH"

Close the shell open again you should see 2.7 when you run python.

Then if you want 3.6 you can simply uncomment your anaconda3 line in your bash profile.

Trying to unlink python will end in tears in Mac OSX.

You will something like this

unlink: /usr/bin/python: Operation not permitted

Hope that helps someone out !! :) :)

I wanted to remove old dependencies from my Maven repository as well. I thought about just running Florian's answer, but I wanted something that I could run over and over without remembering a long linux snippet, and I wanted something with a little bit of configurability -- more of a program, less of a chain of unix commands, so I took the base idea and made it into a (relatively small) Ruby program, which removes old dependencies based on their last access time.

It doesn't remove "old versions" but since you might actually have two different active projects with two different versions of a dependency, that wouldn't have done what I wanted anyway. Instead, like Florian's answer, it removes dependencies that haven't been accessed recently.

If you want to try it out, you can:

1. Visit the GitHub repository
2. Clone the repository, or download the source
3. Optionally inspect the code to make sure it's not malicious
4. Run bin/mvnclean

There are options to override the default Maven repository, ignore files, set the threshold date, but you can read those in the README on GitHub.

I'll probably package it as a Ruby gem at some point after I've done a little more work on it, which will simplify matters (gem install mvnclean; mvnclean) if you already have Ruby installed and operational.

If the exponent is constant and small, expand it out, minimizing the number of multiplications. (For example, x^4 is not optimally x*x*x*x, but y*y where y=x*x. And x^5 is y*y*x where y=x*x. And so on.) For constant integer exponents, just write out the optimized form already; with small exponents, this is a standard optimization that should be performed whether the code has been profiled or not. The optimized form will be quicker in so large a percentage of cases that it's basically always worth doing.

(If you use Visual C++, std::pow(float,int) performs the optimization I allude to, whereby the sequence of operations is related to the bit pattern of the exponent. I make no guarantee that the compiler will unroll the loop for you, though, so it's still worth doing it by hand.)

[edit] BTW pow has a (un)surprising tendency to crop up on the profiler results. If you don't absolutely need it (i.e., the exponent is large or not a constant), and you're at all concerned about performance, then best to write out the optimal code and wait for the profiler to tell you it's (surprisingly) wasting time before thinking further. (The alternative is to call pow and have the profiler tell you it's (unsurprisingly) wasting time -- you're cutting out this step by doing it intelligently.)

From "Fixing LINQ Error: Sequence contains no elements":

When you get the LINQ error "Sequence contains no elements", this is usually because you are using the First() or Single() command rather than FirstOrDefault() and SingleOrDefault().

This can also be caused by the following commands:

• FirstAsync()
• SingleAsync()
• Last()
• LastAsync()
• Max()
• Min()
• Average()
• Aggregate()

SELECT 'DROP TABLE "' || TABLE_NAME || '" CASCADE CONSTRAINTS;' 
FROM user_tables;

user_tables is a system table which contains all the tables of the user the SELECT clause will generate a DROP statement for every table you can run the script

First way is

function function1()
{
  var variable1=12;
  function2(variable1);
}

function function2(val)
{
  var variableOfFunction1 = val;

// Then you will have to use this function for the variable1 so it doesn't really help much unless that's what you want to do. }

Second way is

var globalVariable;
function function1()
{
  globalVariable=12;
  function2();
}

function function2()
{
  var local = globalVariable;
}

editTxt.setOnFocusChangeListener { v, hasFocus ->
            val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
            if (hasFocus) {
                imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY)
            } else {
                imm.hideSoftInputFromWindow(v.windowToken, 0)
            }
        }

In XAMPP installation directory, open %XAMPP_HOME%/php/php.ini file. Uncomment the following line: extension=php_curl.dll

PS: If that doesn't work then check whether %XAMPP_HOME%/php/ext/php_curl.dll file exist or not.

Folks you can see what the optimizer is doing by running a plan. The generic format of looking into a plan is from the MongoDB documentation . i.e. Cursor.plan(). If you really want to dig deeper you can do a cursor.plan(true) for more details.

Having said that if you have an index, your db.col.find().sort({"field":-1}).limit(1) will read one index entry - even if the index is default ascending and you wanted the max entry and one value from the collection.

In other words the suggestions from @yogesh is correct.

You can use scriptlets, however, this is not the way to go. Nowdays inline scriplets or JAVA code in your JSP files is considered a bad habit.

You should read up on JSTL a bit more. If the ansokanInfo object is in your request or session scope, printing the object (toString() method) like this: ${ansokanInfo} can give you some base information. ${ansokanInfo.pSystem} should call the object getter method. If this all works, you can use this:

<c:if test="${ ansokanInfo.pSystem  == 'NAT'}"> tataa </c:if>

tl;dr

I know this is old, but getoptlong wasn't mentioned here and it's probably the best way to parse command line arguments today.

Parsing command line arguments

I strongly recommend getoptlong. It's pretty easy to use and works like a charm. Here is an example extracted from the link above

require 'getoptlong'

opts = GetoptLong.new(
    [ '--help', '-h', GetoptLong::NO_ARGUMENT ],
    [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],
    [ '--name', GetoptLong::OPTIONAL_ARGUMENT ]
)

dir = nil
name = nil
repetitions = 1
opts.each do |opt, arg|
    case opt
        when '--help'
            puts <<-EOF
hello [OPTION] ... DIR

-h, --help:
     show help

--repeat x, -n x:
     repeat x times

--name [name]:
     greet user by name, if name not supplied default is John

DIR: The directory in which to issue the greeting.
            EOF
        when '--repeat'
            repetitions = arg.to_i
        when '--name'
            if arg == ''
                name = 'John'
            else
                name = arg
            end
    end
end

if ARGV.length != 1
    puts "Missing dir argument (try --help)"
    exit 0
end

dir = ARGV.shift

Dir.chdir(dir)
for i in (1..repetitions)
    print "Hello"
    if name
        print ", #{name}"
    end
    puts
end

You can call it like this ruby hello.rb -n 6 --name -- /tmp

What OP is trying to do

In this case I think the best option is to use YAML files as suggested in this answer

Use modulo

whenever a number x is a multiple of some number y, then always x % y equal to 0, which can be used as a check. So use

if (j % 4 == 0) 

If triangle.lborderA is indeed a long then the test in the original code is trivially true, and there is no way to test it. It is also useless.

However, if triangle.lborderA is a double, the comparison is useful and can be tested. isBiggerThanMaxLong(1e300) does return true.

  public static boolean isBiggerThanMaxLong(double in){
    return in > Long.MAX_VALUE;
  }

The existing answers are good and correct, however what if you need to undo the push but:

1. You want to keep the commits locally or you want to keep uncommitted changes
2. You don't know how many commits you just pushed

Use this command to revert the change to the ref:

git push -f origin refs/remotes/origin/<branch>@{1}:<branch>

If you want to add a header to all Jersey responses, you could also use a ContainerResponseFilter, from Jersey's filter documentation :

import java.io.IOException;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.core.Response;

@Provider
public class PoweredByResponseFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
        throws IOException {

            responseContext.getHeaders().add("X-Powered-By", "Jersey :-)");
    }
}

Make sure that you initialize it correctly in your project using the @Provider annotation or through traditional ways with web.xml.

In my case I was using MySql Server version: 8.0.22

I had to add

bind-address        = 0.0.0.0

and change this line to be

mysqlx-bind-address = 0.0.0.0

in file at /etc/mysql/mysql.conf.d

then restart MySQL by running

sudo service mysql restart

Shelving is a way of saving all of the changes on your box without checking in. The changes are persisted on the server. At any later time you or any of your team-mates can "unshelve" them back onto any one of your machines.

It's also great for review purposes. On my team for a check in we shelve up our changes and send out an email with the change description and name of the changeset. People on the team can then view the changeset and give feedback.

FYI: The best way to review a shelveset is with the following command

tfpt review /shelveset:shelvesetName;userName

tfpt is a part of the Team Foundation Power Tools

Do you want to close the modal after submit? Whether the form in inside the modal or external to it you should be able to use jQuery ajax to submit the form.

Here is an example with the form inside the modal:

<a href="#myModal" role="button" class="btn" data-toggle="modal">Launch demo modal</a>

<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
            <h3 id="myModalLabel">Modal header</h3>
    </div>
    <div class="modal-body">
        <form id="myForm" method="post">
          <input type="hidden" value="hello" id="myField">
            <button id="myFormSubmit" type="submit">Submit</button>
        </form>
    </div>
    <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
    </div>
</div>

And the jQuery ajax to get the form fields and submit it..

$('#myFormSubmit').click(function(e){
      e.preventDefault();
      alert($('#myField').val());
      /*
      $.post('http://path/to/post', 
         $('#myForm').serialize(), 
         function(data, status, xhr){
           // do something here with response;
         });
      */
});

Bootstrap 3 example

Bootstrap 4 example

You can use PowerMockito

See the example:

Second second = Mockito.mock(Second.class);
whenNew(Second.class).withNoArguments().thenReturn(second);

But re-factoring is better decision.

$today_at_midnight = strtotime(date("Ymd"));

should give you what you're after.

explanation

What I did was use PHP's date function to get today's date without any references to time, and then pass it to the 'string to time' function which converts a date and time to a epoch timestamp. If it doesn't get a time, it assumes the first second of that day.

References: Date Function: http://php.net/manual/en/function.date.php

String To Time: http://us2.php.net/manual/en/function.strtotime.php

Here is a script I run to restart adb (Android Debug Bridge) server:

#!/usr/bin/env bash

## Summary: restart adb (Android Debug Brdige) server.

## adb binary full path
ADB_BIN=./adb


if pgrep adb >/dev/null 2>&1
then
    echo "adb is running"
    echo "terminating adb ..."
    $ADB_BIN kill-server
    if pgrep adb >/dev/null 2>&1
    then
        echo "did not work"
        echo "kill adb processes by killall"
        killall -9 adb
    else
        echo "terminated"
    fi
else
    echo "adb is not running"
fi

echo "starting adb ..."

$ADB_BIN start-server

echo "adb process:"

echo `pgrep adb`

echo "done"

# END

An alternative way can be this: - recommended as using just one expression -

case when address.country <> '' then address.country
else 'United States'
end as country

Note: Result of checking null by <> operator will return false.
And as documented: NULLIF is equivalent to a searched CASE expression
and COALESCE expression is a syntactic shortcut for the CASE expression.
So, combination of those are using two time of case expression.

To pass a NULL to MySQL, you do just that.

INSERT INTO table (field,field2) VALUES (NULL,3)

So, in your code, check if $intLat, $intLng are empty, if they are, use NULL instead of '$intLat' or '$intLng'.

$intLat = !empty($intLat) ? "'$intLat'" : "NULL";
$intLng = !empty($intLng) ? "'$intLng'" : "NULL";

$query = "INSERT INTO data (notes, id, filesUploaded, lat, lng, intLat, intLng)
          VALUES ('$notes', '$id', TRIM('$imageUploaded'), '$lat', '$long', 
                  $intLat, $intLng)";

The only solution that worked for me was

yarn global add ngrok 
yarn global add exp

with npm I was getting permission errors etc..

Best ever solution ever is here.

if ((self.navigationController?.popViewController(animated: true)) == nil) {
     self.dismiss(animated: true, completion: nil)
}

Check if Pop Navigation provide nil then Dismiss Controller. It can handle Pop and Dismiss vice versa.

The other way to tackle it is to use this code snippet:

JSON.parse(JSON.stringify(response)).data

This feels so wrong but it works

You can use the name attr:

<script type="text/javascript" >
{
window.name ="This is my session";
}
</script> 

You still have to develop for yourself the format to use, or use a wrapper from an already existing library (mootools, Dojo etc).
You can also use cookies, but they are more heavy on performance, as they go back and forth from the client to the server, and are specific to one domain.

According to here, int(11) will take 4 bytes of space that is 32 bits of space with 2^(31) = 2147483648 max value and -2147483648min value. One bit is for sign.

Use this method and pass your array in parameter

Collections.shuffle(arrayList);

This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.

You can now use arraylist which is shuffled.

Inside class definitions you can only declare static members. They have to be defined outside of the class. For compile-time integral constants the standard makes the exception that you can "initialize" members. It's still not a definition, though. Taking the address would not work without definition, for example.

I'd like to mention that I don't see the benefit of using std::string over const char[] for constants. std::string is nice and all but it requires dynamic initialization. So, if you write something like

const std::string foo = "hello";

at namespace scope the constructor of foo will be run right before execution of main starts and this constructor will create a copy of the constant "hello" in the heap memory. Unless you really need RECTANGLE to be a std::string you could just as well write

// class definition with incomplete static member could be in a header file
class A {
    static const char RECTANGLE[];
};

// this needs to be placed in a single translation unit only
const char A::RECTANGLE[] = "rectangle";

There! No heap allocation, no copying, no dynamic initialization.

Cheers, s.

You have to use func setTitleColor(_ color: UIColor?, for state: UIControlState) the same way you set the actual title text. Docs

isbeauty.setTitleColor(UIColorFromRGB("F21B3F"), for: .normal)

Another Option can be Android Accessibility Services Which Greenify Application is using to Force close applications to speedup memory. With having your application accessibility service access you can click on buttons so basically Greenify Application clicks on the force close Button found in settings of an application:

Here you can study accessibility services: https://developer.android.com/reference/android/accessibilityservice/AccessibilityService.html

Here is the Setting Button which accessibility service clicks programitically:

So You can Achieve Killing any Application Including Yours By the following Steps:

1) Register Application for Accessibility Services 2) Depending on your requirements if you want to kill all application get list of All Packages 3) Navigate to their Settings Screen And Click Force Close Button Thats It. I can Share a sample code I also created an application like greenify as an home assignment. Thank you

Update: "The user doesn't, the system handles this automatically." So Basically with this solution we are indirectly using system force close but on the User Demand. So That Both Stay Happy :-)

Original from Sept. 13, 2015:
Quick and easy.

$.each(yourArray, function(index, value){
    $('.element').html( $('.element').html() + '<span>' + value +'</span>')
});

Update Sept 9, 2019: No jQuery is needed to iterate the array.

yourArray.forEach((value) => {
    $(".element").html(`${$(".element").html()}<span>${value}</span>`);
});

/* --- Or without jQuery at all --- */

yourArray.forEach((value) => {
    document.querySelector(".element").innerHTML += `<span>${value}</span>`;
});

Open a terminal:

1. Check MySQL system pref panel, if it says something along the line "Warning, /usr/local/mysql/data is not owned by 'mysql' or '_mysql'

2. If yes, go to the mysql folder cd /usr/local/mysql

3. do a sudo chown -R _mysql data/

4. This will change ownership of the /usr/local/mysql/data and all of its content to own by user '_mysql'

5. Check MySQL system pref panel, it should be saying it's running now, auto-magically. If not start again.

6. Another way to confirm is to do a

   netstat -na | grep 3306

It should say:

tcp46      0      0  *.3306                 *.*                    LISTEN

To see the process owner and process id of the mysqld:

ps aux | grep mysql

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

I think you should use null

SELECT CustomerName AS Customer, null AS Contact 
FROM Customers;

And Remember that Oracle

treats a character value with a length of zero as null.

You Probably Don't Need Derived State

1. Set a key from the parent

When a key changes, React will create a new component instance rather than update the current one. Keys are usually used for dynamic lists but are also useful here.

2. Use getDerivedStateFromProps / componentWillReceiveProps

If key doesn’t work for some reason (perhaps the component is very expensive to initialize)

By using getDerivedStateFromProps you can reset any part of state but it seems a little buggy at this time (v16.7)!, see the link above for the usage

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

The main problem for causing your table unable to migrate, is that you have running query on your "AppServiceProvider.php" try to check your serviceprovider and disable code for the meantime, and run php artisan migrate

when you will change your intent.setType like below you will get

intent.setType("text/plain");

Use android.content.Intent.ACTION_SENDTO to get only the list of e-mail clients, with no facebook or other apps. Just the email clients. Ex:

new Intent(Intent.ACTION_SENDTO);

I wouldn't suggest you get directly to the email app. Let the user choose his favorite email app. Don't constrain him.

If you use ACTION_SENDTO, putExtra does not work to add subject and text to the intent. Use Uri to add the subject and body text.

EDIT: We can use message/rfc822 instead of "text/plain" as the MIME type. However, that is not indicating "only offer email clients" -- it indicates "offer anything that supports message/rfc822 data". That could readily include some application that are not email clients.

message/rfc822 supports MIME Types of .mhtml, .mht, .mime

I found two answers that worked for me, without having to uninstall JDK 10 (or 9), which I need for create-react-app. Both JDK 9 and 10 are incompatible with android-sdk !

Siu Ching Pong -Asuka Kenji- suggests modifying the sdkmanager script, replacing this line:

DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME"'  

with:

DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Note that this mod will be overwritten when updating sdkmanager.
Check out his post, and the one he links to, for more details.
This solution was also one of the solutions mentioned in this github issues thread.

German's post indicates the source of the conflict, and presents fix that will not not be overwritten by updates.
He suggests renaming /Library/Java/JavaVirtualMachines/Info.plist as a means of obscuring it from the script that looks for the highest version of Java that resides on your system. In this way, JDK 8 is returned as the default.
Referring to JDK 10 explicitly, or by setting it to $JAVA_HOME, you can use JDK 10 , instead of the default, whenever needed.
Details are in his post.

This problem is because the machine can't find the the correct ISAM (indexed sequential driver method) registered that Access needs.

It's probably because the machine doesn't have MSACeesss installed? I would make sure you have the latest version of Jet, and if it still doesn't work, find the file Msrd3x40.dll from one of the other machines, copy it somewhere to the Vista machine and call regsvr32 on it (in Admin mode) that should sort it out for you.

This looks confusing because you are taking long as a datatype itself.

long is nothing but just the shorthand for long int when you are using it alone.

long is a modifier, you can use it with double also as long double.

long == long int.

Both of them take 4 bytes.

Differences:

1) Implicit wait is set for the entire duration of the webDriver object. Suppose , you want to wait for a certain duration, let's say 5 seconds before each element or a lot of elements on the webpage load. Now, you wouldn't want to write the same code again and again. Hence, implicit wait. However, if you want to wait for only one element, use explicit.

2) You not only need web element to show up but also to be clickable or to satisfy certain other property of web elements. Such kind of flexibility can be provided by explicit wait only. Specially helpful if dynamic data is being loaded on webpage. You can wait for that element to be developed (not just show up on DOM) using explicit wait.

This is the cleanest way... BY FAR:

Public Function IsDir(s) As Boolean
    IsDir = CreateObject("Scripting.FileSystemObject").FolderExists(s)
End Function

Before doing

git clone https://example.com/root/test.git

make sure that you have added ssh key in your system. Follow this : https://gitlab.com/profile/keys .

Once added run the above command. It will prompt for your gitlab username and password and on authentication, it will be cloned.

Downcasting is allowed when there is a possibility that it succeeds at run time:

Object o = getSomeObject(),
String s = (String) o; // this is allowed because o could reference a String

In some cases this will not succeed:

Object o = new Object();
String s = (String) o; // this will fail at runtime, because o doesn't reference a String

When a cast (such as this last one) fails at runtime a ClassCastException will be thrown.

In other cases it will work:

Object o = "a String";
String s = (String) o; // this will work, since o references a String

Note that some casts will be disallowed at compile time, because they will never succeed at all:

Integer i = getSomeInteger();
String s = (String) i; // the compiler will not allow this, since i can never reference a String.

First open a console then cd to where you've downloaded your file like some-package.whl and use

pip install some-package.whl

Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. I have multiple Python installations, and needed to use the pip associated with Python 3 to install a version 3 wheel.

Update July 2017

Recently I found a comprehensive guide from Grab team about how to approach front-end development in 2017. You can check it out as below.

https://github.com/grab/front-end-guide

I've been also searching for this quite some time since there are a lot of tools out there and each of them benefits us in a different aspect. The community is divided across tools like Browserify, Webpack, jspm, Grunt and Gulp. You might also hear about Yeoman or Slush. That’s not a problem, it’s just confusing for everyone trying to understand a clear path forward.

Anyway, I would like to contribute something.

1. Package Manager

Package managers simplify installing and updating project dependencies, which are libraries such as: jQuery, Bootstrap, etc - everything that is used on your site and isn't written by you.

Browsing all the library websites, downloading and unpacking the archives, copying files into the projects — all of this is replaced with a few commands in the terminal.

NPM

It stands for: Node JS package manager helps you to manage all the libraries your software relies on. You would define your needs in a file called package.json and run npm install in the command line... then BANG, your packages are downloaded and ready to use. It could be used both for front-end and back-end libraries.

Bower

For front-end package management, the concept is the same with NPM. All your libraries are stored in a file named bower.json and then run bower install in the command line.

Bower is recommended their user to migrate over to npm or yarn. Please be careful

Difference between Bower and NPM

The biggest difference between Bower and NPM is that NPM does nested dependency tree while Bower requires a flat dependency tree as below.

Quoting from What is the difference between Bower and npm?

NPM

project root
[node_modules] // default directory for dependencies
 -> dependency A
 -> dependency B
    [node_modules]
    -> dependency A

 -> dependency C
    [node_modules]
    -> dependency B
      [node_modules]
       -> dependency A
    -> dependency D

Bower

project root
[bower_components] // default directory for dependencies
 -> dependency A
 -> dependency B // needs A
 -> dependency C // needs B and D
 -> dependency D

There are some updates on npm 3 Duplication and Deduplication, please open the doc for more detail.

Yarn

A new package manager for JavaScript published by Facebook recently with some more advantages compared to NPM. And with Yarn, you still can use both NPMand Bower registry to fetch the package. If you've installed a package before, yarn creates a cached copy which facilitates offline package installs.

jspm

JSPM is a package manager for the SystemJS universal module loader, built on top of the dynamic ES6 module loader. It is not an entirely new package manager with its own set of rules, rather it works on top of existing package sources. Out of the box, it works with GitHub and npm. As most of the Bower based packages are based on GitHub, we can install those packages using jspm as well. It has a registry that lists most of the commonly used front-end packages for easier installation.

See the different between Bower and jspm: Package Manager: Bower vs jspm

2. Module Loader/Bundling

Most projects of any scale will have their code split between several files. You can just include each file with an individual <script> tag, however, <script> establishes a new HTTP connection, and for small files – which is a goal of modularity – the time to set up the connection can take significantly longer than transferring the data. While the scripts are downloading, no content can be changed on the page.

• The problem of download time can largely be solved by concatenating a group of simple modules into a single file and minifying it.

E.g

<head>
    <title>Wagon</title>
    <script src=“build/wagon-bundle.js”></script>
</head>

• The performance comes at the expense of flexibility though. If your modules have inter-dependency, this lack of flexibility may be a showstopper.

E.g

<head>
    <title>Skateboard</title>
    <script src=“connectors/axle.js”></script>
    <script src=“frames/board.js”></script>
    <!-- skateboard-wheel and ball-bearing both depend on abstract-rolling-thing -->
    <script src=“rolling-things/abstract-rolling-thing.js”></script>
    <script src=“rolling-things/wheels/skateboard-wheel.js”></script>
    <!-- but if skateboard-wheel also depends on ball-bearing -->
    <!-- then having this script tag here could cause a problem -->
    <script src=“rolling-things/ball-bearing.js”></script>
    <!-- connect wheels to axle and axle to frame -->
    <script src=“vehicles/skateboard/our-sk8bd-init.js”></script>
</head>

Computers can do that better than you can, and that is why you should use a tool to automatically bundle everything into a single file.

Then we heard about RequireJS, Browserify, Webpack and SystemJS

RequireJS

It is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Node.

E.g: myModule.js

// package/lib is a dependency we require
define(["package/lib"], function (lib) {
  // behavior for our module
  function foo() {
    lib.log("hello world!");
  }

  // export (expose) foo to other modules as foobar
  return {
    foobar: foo,
  };
});

In main.js, we can import myModule.js as a dependency and use it.

require(["package/myModule"], function(myModule) {
    myModule.foobar();
});

And then in our HTML, we can refer to use with RequireJS.

<script src=“app/require.js” data-main=“main.js” ></script>

Read more about CommonJS and AMD to get understanding easily. Relation between CommonJS, AMD and RequireJS?

Browserify

Set out to allow the use of CommonJS formatted modules in the browser. Consequently, Browserify isn’t as much a module loader as a module bundler: Browserify is entirely a build-time tool, producing a bundle of code that can then be loaded client-side.

Start with a build machine that has node & npm installed, and get the package:

npm install -g –save-dev browserify

Write your modules in CommonJS format

//entry-point.js
var foo = require("../foo.js");
console.log(foo(4));

And when happy, issue the command to bundle:

browserify entry-point.js -o bundle-name.js

Browserify recursively finds all dependencies of entry-point and assembles them into a single file:

<script src="”bundle-name.js”"></script>

Webpack

It bundles all of your static assets, including JavaScript, images, CSS, and more, into a single file. It also enables you to process the files through different types of loaders. You could write your JavaScript with CommonJS or AMD modules syntax. It attacks the build problem in a fundamentally more integrated and opinionated manner. In Browserify you use Gulp/Grunt and a long list of transforms and plugins to get the job done. Webpack offers enough power out of the box that you typically don’t need Grunt or Gulp at all.

Basic usage is beyond simple. Install Webpack like Browserify:

npm install -g –save-dev webpack

And pass the command an entry point and an output file:

webpack ./entry-point.js bundle-name.js

SystemJS

It is a module loader that can import modules at run time in any of the popular formats used today (CommonJS, UMD, AMD, ES6). It is built on top of the ES6 module loader polyfill and is smart enough to detect the format being used and handle it appropriately. SystemJS can also transpile ES6 code (with Babel or Traceur) or other languages such as TypeScript and CoffeeScript using plugins.

Want to know what is the node module and why it is not well adapted to in-browser.

• https://appendto.com/2016/06/the-short-history-of-javascript-module-loaders/

Why jspm and SystemJS?

One of the main goals of ES6 modularity is to make it really simple to install and use any Javascript library from anywhere on the Internet (Github, npm, etc.). Only two things are needed:

• A single command to install the library
• One single line of code to import the library and use it

So with jspm, you can do it.

1. Install the library with a command: jspm install jquery
2. Import the library with a single line of code, no need to external reference inside your HTML file.

display.js

var $ = require('jquery');

$('body').append("I've imported jQuery!");

3. Then you configure these things within System.config({ ... }) before importing your module. Normally when run jspm init, there will be a file named config.js for this purpose.

4. To make these scripts run, we need to load system.js and config.js on the HTML page. After that, we will load the display.js file using the SystemJS module loader.

index.html

<script src="jspm_packages/system.js"></script>
<script src="config.js"></script>
<script>
  System.import("scripts/display.js");
</script>

Noted: You can also use npm with Webpack as Angular 2 has applied it. Since jspm was developed to integrate with SystemJS and it works on top of the existing npm source, so your answer is up to you.

3. Task runner

Task runners and build tools are primarily command-line tools. Why we need to use them: In one word: automation. The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting which previously cost us a lot of times to do with command line or even manually.

Grunt

You can create automation for your development environment to pre-process codes or create build scripts with a config file and it seems very difficult to handle a complex task. Popular in the last few years.

Every task in Grunt is an array of different plugin configurations, that simply get executed one after another, in a strictly independent, and sequential fashion.

grunt.initConfig({
    clean: {
    src: ['build/app.js', 'build/vendor.js']
    },

    copy: {
    files: [{
        src: 'build/app.js',
        dest: 'build/dist/app.js'
    }]
    }

    concat: {
    'build/app.js': ['build/vendors.js', 'build/app.js']
    }

    // ... other task configurations ...

});

grunt.registerTask('build', ['clean', 'bower', 'browserify', 'concat', 'copy']);

Gulp

Automation just like Grunt but instead of configurations, you can write JavaScript with streams like it's a node application. Prefer these days.

This is a Gulp sample task declaration.

//import the necessary gulp plugins
var gulp = require("gulp");
var sass = require("gulp-sass");
var minifyCss = require("gulp-minify-css");
var rename = require("gulp-rename");

//declare the task
gulp.task("sass", function (done) {
  gulp
    .src("./scss/ionic.app.scss")
    .pipe(sass())
    .pipe(gulp.dest("./www/css/"))
    .pipe(
      minifyCss({
        keepSpecialComments: 0,
      })
    )
    .pipe(rename({ extname: ".min.css" }))
    .pipe(gulp.dest("./www/css/"))
    .on("end", done);
});

4. Scaffolding tools

Slush and Yeoman

You can create starter projects with them. For example, you are planning to build a prototype with HTML and SCSS, then instead of manually create some folder like scss, css, img, fonts. You can just install yeoman and run a simple script. Then everything here for you.

Find more here.

npm install -g yo
npm install --global generator-h5bp
yo h5bp

My answer is not matched with the content of the question but when I'm searching for this knowledge on Google, I always see the question on top so that I decided to answer it in summary. I hope you guys found it helpful.

If you like this post, you can read more on my blog at trungk18.com. Thanks for visiting :)

res.send() implements res.write, res.setHeaders and res.end:

1. It checks the data you send and sets the correct response headers.
2. Then it streams the data with res.write.
3. Finally, it uses res.end to set the end of the request.

There are some cases in which you will want to do this manually, for example, if you want to stream a file or a large data set. In these cases, you will want to set the headers yourself and use res.write to keep the stream flow.

I would use a nice UML example.

Take a university that has 1 to 20 different departments and each department has 1 to 5 professors. There is a composition link between a University and its' departments. There is an aggregation link between a department and its' professors.

Composition is just a STRONG aggregation, if the university is destroyed then the departments should also be destroyed. But we shouldn't kill the professors even if their respective departments disappear.

In java :

public class University {

     private List<Department> departments;

     public void destroy(){
         //it's composition, when I destroy a university I also destroy the departments. they cant live outside my university instance
         if(departments!=null)
             for(Department d : departments) d.destroy();
         departments.clean();
         departments = null;
     }
}

public class Department {

     private List<Professor> professors;
     private University university;

     Department(University univ){
         this.university = univ;
         //check here univ not null throw whatever depending on your needs
     }

     public void destroy(){
         //It's aggregation here, we just tell the professor they are fired but they can still keep living
         for(Professor p:professors)
             p.fire(this);
         professors.clean();
         professors = null;
     }
}

public class Professor {

     private String name;
     private List<Department> attachedDepartments;

     public void destroy(){

     }

     public void fire(Department d){
         attachedDepartments.remove(d);
     }
}

Something around this.

EDIT: an example as requested

public class Test
{
    public static void main(String[] args)
    {
        University university = new University();
        //the department only exists in the university
        Department dep = university.createDepartment();
        // the professor exists outside the university
        Professor prof = new Professor("Raoul");
        System.out.println(university.toString());
        System.out.println(prof.toString());

        dep.assign(prof);
        System.out.println(university.toString());
        System.out.println(prof.toString());
        dep.destroy();

        System.out.println(university.toString());
        System.out.println(prof.toString());

    }

        p.join(this);
    }

        professors.remove(p);
        p.quit(this);
    }

    public void destroy() {
        //It's aggregation here, we just tell the professor they are fired but they can still keep living
        System.out.println("Destroying department");
        professors.forEach(professor -> professor.quit(this));
        professors = null;
    }

    @Override
    public String toString() {
        return professors == null
                ? "Department " + name + " doesn't exists anymore"

}

Professor class

import java.util.ArrayList;
import java.util.List;

public class Professor {

    private final String name;
    private final List<Department> attachedDepartments = new ArrayList<>();

        this.name = name;
    }

    public void destroy() {

    }

    public void join(Department d) {
        attachedDepartments.add(d);
    }

    public void quit(Department d) {
        attachedDepartments.remove(d);
    }

    public String getName() {
        return name;
    }

    @Override
    public String toString() {
        return "Professor " + name + " working for " + attachedDepartments.size() + " department(s)\n";
    }
}

The implementation is debatable as it depends on how you need to handle creation, hiring deletion etc. Unrelevant for the OP

If you don't see the Active Directory, it's because you did not install AD LS Users and Computer Feature. Go to Manage - Add Roles & Features. Within Add Roles and Features Wizard, on Features tab, select Remote Server Administration Tools, select - Role Admininistration Tools - Select AD DS and DF LDS Tools.

After that, you can see the PS Active Directory package.

Just as string.gmatch will find patterns in a string, this function will find the things between patterns:

function string:split(pat)
  pat = pat or '%s+'
  local st, g = 1, self:gmatch("()("..pat..")")
  local function getter(segs, seps, sep, cap1, ...)
    st = sep and seps + #sep
    return self:sub(segs, (seps or 0) - 1), cap1 or sep, ...
  end
  return function() if st then return getter(st, g()) end end
end

By default it returns whatever is separated by whitespace.

As no answer is complete for the current way to solve this problem, I try to give instructions for a complete solution. Please comment if something is missing or could be done better.

General information

First, there exist some libraries that want to solve the problem but they all seem outdated or are missing some features:

• https://github.com/delight-im/Android-Languages
  • Outdated (see issues)
  • When selecting a language in the UI, it always shows all languages (hardcoded in the library), not only those where translations exist
• https://github.com/akexorcist/Android-LocalizationActivity
  • Seems quite sophisticated and might use a similar approach as shown below

Further I think writing a library might not be a good/easy way to solve this problem because there is not very much to do, and what has to be done is rather changing existing code than using something completely decoupled. Therefore I composed the following instructions that should be complete.

My solution is mainly based on https://github.com/gunhansancar/ChangeLanguageExample (as already linked to by localhost). It is the best code I found to orientate at. Some remarks:

• As necessary, it provides different implementations to change locale for Android N (and above) and below
• It uses a method updateViews() in each Activity to manually update all strings after changing locale (using the usual getString(id)) which is not necessary in the approach shown below
• It only supports languages and not complete locales (which also include region (country) and variant codes)

I changed it a bit, decoupling the part which persists the chosen locale (as one might want to do that separately, as suggested below).

Solution

The solution consists of the following two steps:

• Permanently change the locale to be used by the app
• Make the app use the custom locale set, without restarting

Step 1: Change the locale

Use the class LocaleHelper, based on gunhansancar's LocaleHelper:

• Add a ListPreference in a PreferenceFragment with the available languages (has to be maintained when languages should be added later)

import android.annotation.TargetApi;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.res.Configuration;
import android.content.res.Resources;
import android.os.Build;
import android.preference.PreferenceManager;

import java.util.Locale;

import mypackage.SettingsFragment;

/**
 * Manages setting of the app's locale.
 */
public class LocaleHelper {

    public static Context onAttach(Context context) {
        String locale = getPersistedLocale(context);
        return setLocale(context, locale);
    }

    public static String getPersistedLocale(Context context) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getString(SettingsFragment.KEY_PREF_LANGUAGE, "");
    }

    /**
     * Set the app's locale to the one specified by the given String.
     *
     * @param context
     * @param localeSpec a locale specification as used for Android resources (NOTE: does not
     *                   support country and variant codes so far); the special string "system" sets
     *                   the locale to the locale specified in system settings
     * @return
     */
    public static Context setLocale(Context context, String localeSpec) {
        Locale locale;
        if (localeSpec.equals("system")) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                locale = Resources.getSystem().getConfiguration().getLocales().get(0);
            } else {
                //noinspection deprecation
                locale = Resources.getSystem().getConfiguration().locale;
            }
        } else {
            locale = new Locale(localeSpec);
        }
        Locale.setDefault(locale);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            return updateResources(context, locale);
        } else {
            return updateResourcesLegacy(context, locale);
        }
    }

    @TargetApi(Build.VERSION_CODES.N)
    private static Context updateResources(Context context, Locale locale) {
        Configuration configuration = context.getResources().getConfiguration();
        configuration.setLocale(locale);
        configuration.setLayoutDirection(locale);

        return context.createConfigurationContext(configuration);
    }

    @SuppressWarnings("deprecation")
    private static Context updateResourcesLegacy(Context context, Locale locale) {
        Resources resources = context.getResources();

        Configuration configuration = resources.getConfiguration();
        configuration.locale = locale;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            configuration.setLayoutDirection(locale);
        }

        resources.updateConfiguration(configuration, resources.getDisplayMetrics());

        return context;
    }
}

Create a SettingsFragment like the following:

import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceFragment;
import android.preference.PreferenceManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import mypackage.LocaleHelper;
import mypackage.R;

/**
 * Fragment containing the app's main settings.
 */
public class SettingsFragment extends PreferenceFragment implements SharedPreferences.OnSharedPreferenceChangeListener {
    public static final String KEY_PREF_LANGUAGE = "pref_key_language";

    public SettingsFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_settings, container, false);
        return view;
    }

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
        switch (key) {
            case KEY_PREF_LANGUAGE:
                LocaleHelper.setLocale(getContext(), PreferenceManager.getDefaultSharedPreferences(getContext()).getString(key, ""));
                getActivity().recreate(); // necessary here because this Activity is currently running and thus a recreate() in onResume() would be too late
                break;
        }
    }

    @Override
    public void onResume() {
        super.onResume();
        // documentation requires that a reference to the listener is kept as long as it may be called, which is the case as it can only be called from this Fragment
        getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    public void onPause() {
        super.onPause();
        getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
    }
}

Create a resource locales.xml listing all locales with available translations in the following way (list of locale codes):

<!-- Lists available locales used for setting the locale manually.
     For now only language codes (locale codes without country and variant) are supported.
     Has to be in sync with "settings_language_values" in strings.xml (the entries must correspond).
  -->
<resources>
    <string name="system_locale" translatable="false">system</string>
    <string name="default_locale" translatable="false"></string>
    <string-array name="locales">
        <item>@string/system_locale</item> <!-- system setting -->
        <item>@string/default_locale</item> <!-- default locale -->
        <item>de</item>
    </string-array>
</resources>

In your PreferenceScreen you can use the following section to let the user select the available languages:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory
        android:title="@string/preferences_category_general">
        <ListPreference
            android:key="pref_key_language"
            android:title="@string/preferences_language"
            android:dialogTitle="@string/preferences_language"
            android:entries="@array/settings_language_values"
            android:entryValues="@array/locales"
            android:defaultValue="@string/system_locale"
            android:summary="%s">
        </ListPreference>
    </PreferenceCategory>
</PreferenceScreen>

which uses the following strings from strings.xml:

<string name="preferences_category_general">General</string>
<string name="preferences_language">Language</string>
<!-- NOTE: Has to correspond to array "locales" in locales.xml (elements in same orderwith) -->
<string-array name="settings_language_values">
    <item>Default (System setting)</item>
    <item>English</item>
    <item>German</item>
</string-array>

Step 2: Make the app use the custom locale

Now setup each Activity to use the custom locale set. The easiest way to accomplish this is to have a common base class for all activities with the following code (where the important code is in attachBaseContext(Context base) and onResume()):

import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

import mypackage.LocaleHelper;
import mypackage.R;

/**
 * {@link AppCompatActivity} with main menu in the action bar. Automatically recreates
 * the activity when the locale has changed.
 */
public class MenuAppCompatActivity extends AppCompatActivity {
    private String initialLocale;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initialLocale = LocaleHelper.getPersistedLocale(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.menu_settings:
                Intent intent = new Intent(this, SettingsActivity.class);
                startActivity(intent);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(LocaleHelper.onAttach(base));
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (initialLocale != null && !initialLocale.equals(LocaleHelper.getPersistedLocale(this))) {
            recreate();
        }
    }
}

What it does is

• Override attachBaseContext(Context base) to use the locale previously persisted with LocaleHelper
• Detect a change of the locale and recreate the Activity to update its strings

Notes on this solution

• Recreating an Activity does not update the title of the ActionBar (as already observed here: https://github.com/gunhansancar/ChangeLanguageExample/issues/1).

  • This can be achieved by simply having a setTitle(R.string.mytitle) in the onCreate() method of each activity.

• It lets the user chose the system default locale, as well as the default locale of the app (which can be named, in this case "English").

• Only language codes, no region (country) and variant codes (like fr-rCA) are supported so far. To support full locale specifications, a parser similar to that in the Android-Languages library can be used (which supports region but no variant codes).

  • If someone finds or has written a good parser, add a comment so I can include it in the solution.

If for the entire report you need an alternating color, you can use the DataSet your Tablix is bound to for a report-wide identity rownumber on the report and use that in the RowNumber function...

=IIf(RowNumber("DataSet1")  Mod 2 = 1, "White","Blue")

That is not possible du to the Box Model. However you could use a workaround with css3's border-image, or border-color in general css.

However im unsure whether you may have a problem with resetting. Some browsers do set a margin to html as well. See Eric Meyers Reset CSS for more!

html{margin:0;padding:0;}

It's complaining about

COUNT(DISTINCT dNum) AS ud 

inside the subquery. Only one column can be returned from the subquery unless you are performing an exists query. I'm not sure why you want to do a count on the same column twice, superficially it looks redundant to what you are doing. The subquery here is only a filter it is not the same as a join. i.e. you use it to restrict data, not to specify what columns to get back.

i even tryed to avoid this, just in case doing the Abort on the thread manually, but i rather leave it with the "CompleteRequest" and move on - my code has return commands after redirects anyway. So this can be done

public static void Redirect(string VPathRedirect, global::System.Web.UI.Page Sender)
{
    Sender.Response.Redirect(VPathRedirect, false);
    global::System.Web.UI.HttpContext.Current.ApplicationInstance.CompleteRequest();
}

There is a lot of confusion about IdentityDbContext, a quick search in Stackoverflow and you'll find these questions:
" Why is Asp.Net Identity IdentityDbContext a Black-Box?
How can I change the table names when using Visual Studio 2013 AspNet Identity?
Merge MyDbContext with IdentityDbContext"

To answer to all of these questions we need to understand that IdentityDbContext is just a class inherited from DbContext.
Let's take a look at IdentityDbContext source:

}

Based on the source code if we want to merge IdentityDbContext with our DbContext we have two options:

First Option:
Create a DbContext which inherits from IdentityDbContext and have access to the classes.

   public class ApplicationDbContext 
    : IdentityDbContext
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

Extra Notes:

1) We can also change asp.net Identity default table names with the following solution:

    public class ApplicationDbContext : IdentityDbContext
    {    
        public ApplicationDbContext(): base("DefaultConnection")
        {
        }

        protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<IdentityUser>().ToTable("user");
            modelBuilder.Entity<ApplicationUser>().ToTable("user");

            modelBuilder.Entity<IdentityRole>().ToTable("role");
            modelBuilder.Entity<IdentityUserRole>().ToTable("userrole");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("userclaim");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("userlogin");
        }
    }

2) Furthermore we can extend each class and add any property to classes like 'IdentityUser', 'IdentityRole', ...

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
    public ApplicationRole() 
    {
        this.Id = Guid.NewGuid().ToString();
    }

    public ApplicationRole(string name)
        : this()
    {
        this.Name = name;
    }

    // Add any custom Role properties/code here
}


// Must be expressed in terms of our custom types:
public class ApplicationDbContext 
    : IdentityDbContext<ApplicationUser, ApplicationRole, 
    string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.

Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from DbContext and implement our customized version of "OnModelCreating(ModelBuilder builder)" from the IdentityDbContext source code

You could try this.

=IF(A1=1,B1,TRIM(" "))

If you put this formula in cell C1, then you could test if this cell is blank in another cells

=ISBLANK(C1)

You should see TRUE. I've tried on Microsoft Excel 2013. Hope this helps.

The key is the sql query, which you will set up as a string:

$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";

Note that there are a lot of ways to specify NOT. Another one that works just as well is:

$sqlquery = "SELECT field1, field2 FROM table WHERE columnA != 'x' AND columbB != 'y'";

Here is a full example of how to use it:

$link = mysql_connect($dbHost,$dbUser,$dbPass) or die("Unable to connect to database");
mysql_select_db("$dbName") or die("Unable to select database $dbName");
$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";
$result=mysql_query($sqlquery);

while ($row = mysql_fetch_assoc($result) {
//do stuff
}

You can do whatever you would like within the above while loop. Access each field of the table as an element of the $row array which means that $row['field1'] will give you the value for field1 on the current row, and $row['field2'] will give you the value for field2.

Note that if the column(s) could have NULL values, those will not be found using either of the above syntaxes. You will need to add clauses to include NULL values:

$sqlquery = "SELECT field1, field2 FROM table WHERE (NOT columnA = 'x' OR columnA IS NULL) AND (NOT columbB = 'y' OR columnB IS NULL)";

you can change that using label property in property panel. This screen shot is example that

You can use URL encoding to encode the newline as %0A.

mailto:[email protected]?subject=test&body=type%20your%0Amessage%20here

While the above appears to work in many cases, user olibre points out that the RFC governing the mailto URI scheme specifies that %0D%0A (carriage return + line feed) should be used instead of %0A (line feed). See also: Newline Representations.

Use the rails style sheet tag to link your main.css like this

<%= stylesheet_link_tag "main" %>

Go to

config/initializers/assets.rb

Once inside the assets.rb add the following code snippet just below the Rails.application.config.assets.version = '1.0'

Rails.application.config.assets.version = '1.0'
Rails.application.config.assets.precompile += %w( main.css )

Restart your server.

On SQL Server, this will list all the indexes for a specified table:

select * from sys.indexes
where object_id = (select object_id from sys.objects where name = 'MYTABLE')

This query will list all tables without an index:

SELECT name
FROM sys.tables 
WHERE OBJECTPROPERTY(object_id,'IsIndexed') = 0

And this is an interesting MSDN FAQ on a related subject:
Querying the SQL Server System Catalog FAQ

Here is a truly and completely RESTful authentication solution:

1. Create a public/private key pair on the authentication server.
2. Distribute the public key to all servers.

3. When a client authenticates:

   3.1. issue a token which contains the following:

   • Expiration time
   • users name (optional)
   • users IP (optional)
   • hash of a password (optional)

   3.2. Encrypt the token with the private key.

   3.3. Send the encrypted token back to the user.

4. When the user accesses any API they must also pass in their auth token.

5. Servers can verify that the token is valid by decrypting it using the auth server's public key.

This is stateless/RESTful authentication.

Note, that if a password hash were included the user would also send the unencrypted password along with the authentication token. The server could verify that the password matched the password that was used to create the authentication token by comparing hashes. A secure connection using something like HTTPS would be necessary. Javascript on the client side could handle getting the user's password and storing it client side, either in memory or in a cookie, possibly encrypted with the server's public key.

That because your csv file is in invalid format, maybe the line break in your text file is not the \n or \r

and, using c/c++ to parse text is not a good idea. try awk:

 $awk -F"," '{print "ID="$1"\tName="$2"\tAge="$3"\tGender="$4}' 1.csv
 ID=0   Name=Filipe Age=19  Gender=M
 ID=1   Name=Maria  Age=20  Gender=F
 ID=2   Name=Walter Age=60  Gender=M

The way to do it would be with a boolean at a higher scope:

var hasBeenClicked = false;
jQuery('#id').click(function () {
    hasBeenClicked = true;
});

if (hasBeenClicked) {
    // The link has been clicked.
} else {
    // The link has not been clicked.
}

I believe a short video showing all the details if you have Anaconda is the following for mac (it is very similar to windows users as well) just open Anaconda navigator and everything is just the same (almost!)

https://www.youtube.com/watch?v=gDzAm25CORk

Then go to jupyter notebook and code

!pip install tensorflow

Then

import tensorflow as tf

It work for me! :)

Very late answer, but I think my answer is more straight forward for specific use cases where users want to simply insert (copy) data from table A into table B:

INSERT INTO table_b (col1, col2, col3, col4, col5, col6)
SELECT col1, 'str_val', int_val, col4, col5, col6
FROM table_a

There is no need to download any binaries or files or follow difficult installation instructions.

All you really needed to do is:

sudo apt update && sudo apt install android-sdk

Update: Ubuntu 18.04 only

One option is to use the delete method as follows:

StringBuffer sb = new StringBuffer();
for (int n = 0; n < 10; n++) {
   sb.append("a");

   // This will clear the buffer
   sb.delete(0, sb.length());
}

Another option (bit cleaner) uses setLength(int len):

sb.setLength(0);

See Javadoc for more info:

It's very simple just use a function on javaScript and call it onclick

   <script type="text/javascript">
            function change()
            {
            document.getElementById("catestory").style.backgroundColor="#666666";
            }
            </script>

    <a href="#" onclick="change()">Change Bacckground Color</a>

I find it much easier to "extend" via assigning in a bigger matrix. E.g.

import numpy as np
p = np.array([[1,2], [3,4]])
g = np.array(range(20))
g.shape = (4,5)
g[0:2, 0:2] = p

Here are the arrays:

p

   array([[1, 2],
       [3, 4]])

g:

array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])

and the resulting g after assignment:

   array([[ 1,  2,  2,  3,  4],
       [ 3,  4,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])

By the looks of it you need to actually pass drawImage an image object like so

var canvas = document.getElementById("c");_x000D_
var ctx = canvas.getContext("2d");_x000D_
_x000D_
var image = new Image();_x000D_
image.onload = function() {_x000D_
  ctx.drawImage(image, 0, 0);_x000D_
};_x000D_
image.src = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

<canvas id="c"></canvas>

I've tried it in chrome and it works fine.

The biggest draw back I've found with using ConfigureAwait(false) is that the thread culture is reverted to the system default. If you've configured a culture e.g ...

<system.web>
    <globalization culture="en-AU" uiCulture="en-AU" />    
    ...

and you're hosting on a server whose culture is set to en-US, then you will find before ConfigureAwait(false) is called CultureInfo.CurrentCulture will return en-AU and after you will get en-US. i.e.

// CultureInfo.CurrentCulture ~ {en-AU}
await xxxx.ConfigureAwait(false);
// CultureInfo.CurrentCulture ~ {en-US}

If your application is doing anything which requires culture specific formatting of data, then you'll need to be mindful of this when using ConfigureAwait(false).

I removed Android dependencies from build path and it worked.

Quick fix:

Change -Xmx1024m to -Xmx512m in eclipse.ini (file located at the same level where eclipse.exe is present). And it will work like a charm.

For those who have Underscore.js included in their project you can do:

_({a:'', b:''}).size() // => 2

or functional style:

_.size({a:'', b:''}) // => 2

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

From 1700 to 1917, official calendar was the Julian calendar. Since then they we use the Gregorian calendar system. The transition from the Julian to Gregorian calendar system occurred in 1918, when the next day after January 31st was February 14th. This means that 32nd day in 1918, was the February 14th.

In both calendar systems, February is the only month with a variable amount of days, it has 29 days during a leap year, and 28 days during all other years. In the Julian calendar, leap years are divisible by 4 while in the Gregorian calendar, leap years are either of the following:

Divisible by 400.

Divisible by 4 and not divisible by 100.

So the program for leap year will be:

Python:

def leap_notleap(year):

    yr = ''
    if year <= 1917:
        if year % 4 == 0:
            yr = 'leap'
        else:
            yr = 'not leap'
    elif year >= 1919:
        if (year % 400 == 0) or (year % 4 == 0 and year % 100 != 0):
            yr = 'leap'
        else:
            yr = 'not leap'
    else:
        yr = 'none actually, since feb had only 14 days'

    return yr

To remove the left-most word, you'll need to use either RIGHT or SUBSTRING. Assuming you know how many characters are involved, that would look either of the following:

SELECT RIGHT('Hello World', 5)
SELECT SUBSTRING('Hello World', 6, 100)

If you don't know how many characters that first word has, you'll need to find out using CHARINDEX, then substitute that value back into SUBSTRING:

SELECT SUBSTRING('Hello World', CHARINDEX(' ', 'Hello World') + 1, 100)

This finds the position of the first space, then takes the remaining characters to the right.

It's because of .NET Framework 4.5 is replacing .NET Framework 4.0. I uninstalled Visual Studio 2010 several times with no luck. When I removed .NET Framework 4.5 and reinstalled Visual Studio 2010 it went fine.

An index is just a data structure that makes the searching faster for a specific column in a database. This structure is usually a b-tree or a hash table but it can be any other logic structure.

Wasn't really happy with the output of jsbeautifier.org for what I was putting in, so I did some more searching and found this site: http://www.centralinternet.com.br/javascript-beautifier

Worked extremely well for me.

try this...    
<script type="text/javascript">
    function test(){
    var av=document.getElementById("mytext").value;
    alert(av);
    }
    </script>

    <input type="text" value="" id="mytext">
    <input type="button" onclick="test()" value="go" />

for (int i = 0; i < nodeList.getLength(); i++)

change to

for (int i = 0, len = nodeList.getLength(); i < len; i++)

to be more efficient.

The second way of javanna answer may be the best as it tends to use a flatter, predictable memory model.

notnot, resurrecting this ancient question because it had a simple solution that wasn't mentioned. (Found your question while doing some research for a regex bounty quest.)

I'm faced with a situation where I have to match an (A and ~B) pattern.

The basic regex for this is frighteningly simple: B|(A)

You just ignore the overall matches and examine the Group 1 captures, which will contain A.

An example (with all the disclaimers about parsing html in regex): A is digits, B is digits within <a tag

The regex: <a.*?<\/a>|(\d+)

Demo (look at Group 1 in the lower right pane)

I struggled with the same issue when trying to feed floats to the classifiers. I wanted to keep floats and not integers for accuracy. Try using regressor algorithms. For example:

import numpy as np
from sklearn import linear_model
from sklearn import svm

classifiers = [
    svm.SVR(),
    linear_model.SGDRegressor(),
    linear_model.BayesianRidge(),
    linear_model.LassoLars(),
    linear_model.ARDRegression(),
    linear_model.PassiveAggressiveRegressor(),
    linear_model.TheilSenRegressor(),
    linear_model.LinearRegression()]

trainingData    = np.array([ [2.3, 4.3, 2.5],  [1.3, 5.2, 5.2],  [3.3, 2.9, 0.8],  [3.1, 4.3, 4.0]  ])
trainingScores  = np.array( [3.4, 7.5, 4.5, 1.6] )
predictionData  = np.array([ [2.5, 2.4, 2.7],  [2.7, 3.2, 1.2] ])

for item in classifiers:
    print(item)
    clf = item
    clf.fit(trainingData, trainingScores)
    print(clf.predict(predictionData),'\n')

The accepted answer is good, however, I would have needed various library configurations within my multi-project Gradle build to use the same 3rd-party Java library.

Adding '$rootProject.projectDir' to the 'dir' path element within my 'allprojects' closure meant each sub-project referenced the same 'libs' directory, and not a version local to that sub-project:

//gradle.build snippet
allprojects {
    ...

    repositories {
        //All sub-projects will now refer to the same 'libs' directory
        flatDir {
            dirs "$rootProject.projectDir/libs"
        }
        mavenCentral()
    }

    ...
}

EDIT by Quizzie: changed "${rootProject.projectDir}" to "$rootProject.projectDir" (works in the newest Gradle version).

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

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

That should work via HTTPRewriteModule.

Example rewrite from www.example.com to example.com:

server {    
    server_name www.example.com;    
    rewrite ^ http://example.com$request_uri? permanent; 
}

Remove all but 5 (or whatever number) of the most recent files in a directory.

rm `ls -t | awk 'NR>5'`

Or you can just run the following command and you will see all databases of the Redis instance without firing up redis-cli:

$ redis-cli INFO | grep ^db
db0:keys=1500,expires=2
db1:keys=200000,expires=1
db2:keys=350003,expires=1

For the sake of completeness: The float property removes a element from the flow of the HTML too, e.g.

float: right

Matt's answer is definitely the right answer. However, here's an alternative solution for comic relief purposes:

do.call(paste, c(as.list(sdata), sep = ""))

Just used this solution with Homebrew 0.9.5 and it seemed like a quick solution to upgrade to the latest stable version of node.

brew update

This will install the latest version

brew install node

Unlink your current version of node use, node -v, to find this

brew unlink node012

This will change to the most up to date version of node.

brew link node

Note: This solution worked as a result of me getting this error:

Error: No such keg: /usr/local/Cellar/node

I had the same problem and realized I was setting both the LayoutManager and adapter after retrieving the data from my source instead of setting the two in the onCreate method.

salesAdapter = new SalesAdapter(this,ordersList);
        salesView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
        salesView.setAdapter(salesAdapter);

Then notified the adapter on data change

               //get the Orders
                Orders orders;
                JSONArray ordersArray = jObj.getJSONArray("orders");
                    for (int i = 0; i < ordersArray.length() ; i++) {
                        JSONObject orderItem = ordersArray.getJSONObject(i);
                        //populate the Order model

                        orders = new Orders(
                                orderItem.getString("order_id"),
                                orderItem.getString("customer"),
                                orderItem.getString("date_added"),
                                orderItem.getString("total"));
                        ordersList.add(i,orders);
                        salesAdapter.notifyDataSetChanged();
                    }

Add the frameBorder attribute (note the capital ‘B’).

So it would look like:

<iframe src="myURL" width="300" height="300" frameBorder="0">Browser not compatible.</iframe>

The error message will include the name of the constraint that was violated (there may be more than one unique constraint on a table). You can use that constraint name to identify the column(s) that the unique constraint is declared on

SELECT column_name, position
  FROM all_cons_columns
 WHERE constraint_name = <<name of constraint from the error message>>
   AND owner           = <<owner of the table>>
   AND table_name      = <<name of the table>>

Once you know what column(s) are affected, you can compare the data you're trying to INSERT or UPDATE against the data already in the table to determine why the constraint is being violated.

Since id is an attribute don't create an id element, just do this:

myPara.setAttribute("id", "id_you_like");

the window.top property should be able to give what you need.

E.g.

alert(top.location.href)

See http://cross-browser.com/talk/inter-frame_comm.html

In HTML:

<div (mouseover)="funcName1() (mouseout)="funcName2()">
   // Do what you want 
</div>

In TypeScript:

funcName1(){
 //Do Something
}
funcName2(){
//Do Something
}

use IDENTITY(1,1) while creating the table eg

CREATE TABLE SAMPLE(
[Id]     [int]  IDENTITY(1,1) NOT NULL,
[Status] [smallint] NOT NULL,

CONSTRAINT [PK_SAMPLE] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)
)

2015-4-22: It looks like an IPython update means that --to pdf should be used instead of --to latex --post PDF. There is a related Github issue.

These codes will work fine all times.

At first set the activated event handler in XAML:

Activated="Window_Activated"

Add below line to your Main Window constructor block:

public MainWindow()
{
    InitializeComponent();
    this.LocationChanged += (sender, e) => this.Window_Activated(sender, e);
}

And inside the activated event handler copy this codes:

private void Window_Activated(object sender, EventArgs e)
{
    if (Application.Current.Windows.Count > 1)
    {
        foreach (Window win in Application.Current.Windows)
            try
            {
                if (!win.Equals(this))
                {
                    if (!win.IsVisible)
                    {
                        win.ShowDialog();
                    }

                    if (win.WindowState == WindowState.Minimized)
                    {
                        win.WindowState = WindowState.Normal;
                    }

                    win.Activate();
                    win.Topmost = true;
                    win.Topmost = false;
                    win.Focus();
                }
            }
            catch { }
    }
    else
        this.Focus();
}

These steps will works fine and will bring to front all other windows into their parents window.

Easiest way to do it with javax.xml.bind.DatatypeConverter:

    String hex = "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";
    byte[] s = DatatypeConverter.parseHexBinary(hex);
    System.out.println(new String(s));

normally I extract the embedded image with 'pdfimages' at the native resolution, then use ImageMagick's convert to the needed format:

$ pdfimages -list fileName.pdf
$ pdfimages fileName.pdf fileName   # save in .ppm format
$ convert fileName-000.ppm fileName-000.png

this generate the best and smallest result file.

Note: For lossy JPG embedded images, you had to use -j:

$ pdfimages -j fileName.pdf fileName   # save in .jpg format

With recent poppler you can use -all that save lossy as jpg and lossless as png

On little provided Win platform you had to download a recent (0.37 2015) 'poppler-util' binary from: http://blog.alivate.com.au/poppler-windows/

Just to share a similar problem I had in case it might help some one, I was using:

var NextSlidePage = $("bottomcontent" + Slide + ".html");

to make the variable for the load function, But I should have used:

var NextSlidePage = "bottomcontent" + Slide + ".html";

without the $( )

Don't know why but now it works! Thanks, finally i saw what was going wrong from this post!

The functional way of achieving this is to unzip the list using:

sample = [(2, 9), (2, 9), (8, 9), (10, 9), (23, 26), (1, 9), (43, 44)]
first,snd = zip(*sample)
print(first,snd)

(2, 2, 8, 10, 23, 1, 43) (9, 9, 9, 9, 26, 9, 44)

If you want to just display some text in your .cshtml page, I do not recommend @Html.Label and also not to use the html label as well. The element represents a caption in a user interface. and you'll see that in the case of @Html.Label, a for attribute is added, referring to the id of a, possibly non-existent, element. The value of this attribute is the value of the model field, in which non-alphanumerics are replaced by underscores. You should use @Html.Display or @Html.DisplayFor, possibly wrapped in some plain html elements line span or p.

For whatever it's worth now: here is yet another solution:

• create two divs within a display: inline-block
• in the first div, put a table with only the header (header table tabhead)
• in the 2nd div, put a table with header and data (data table / full table tabfull)
• use JavaScript, use setTimeout(() => {/*...*/}) to execute code after render / after filling the table with results from fetch
• measure the width of each th in the data table (using clientWidth)
• apply the same width to the counterpart in the header table
• set visibility of the header of the data table to hidden and set the margin top to -1 * height of data table thead pixels

With a few tweaks, this is the method to use (for brevity / simplicity, I used d3js, the same operations can be done using plain DOM):

setTimeout(() => { // pass one cycle
  d3.select('#tabfull')
    .style('margin-top', (-1 * d3.select('#tabscroll').select('thead').node().getBoundingClientRect().height) + 'px')
    .select('thead')
      .style('visibility', 'hidden');
  let widths=[]; // really rely on COMPUTED values
  d3.select('#tabfull').select('thead').selectAll('th')
    .each((n, i, nd) => widths.push(nd[i].clientWidth));
  d3.select('#tabhead').select('thead').selectAll('th')
    .each((n, i, nd) => d3.select(nd[i])
          .style('padding-right', 0)
          .style('padding-left', 0)
          .style('width', widths[i]+'px'));
})

Waiting on render cycle has the advantage of using the browser layout engine thoughout the process - for any type of header; it's not bound to special condition or cell content lengths being somehow similar. It also adjusts correctly for visible scrollbars (like on Windows)

I've put up a codepen with a full example here: https://codepen.io/sebredhh/pen/QmJvKy

In order to convert string to char

 String str = "abcd";
char arr [] = new char[len]; // len is the length of the array
arr = str.toCharArray();

First, Mv = numpy.asarray(M.T), which gives you a 4x1 but 2D array.

Then, perform A = Mv[0,:], which gives you what you want. You could put them together, as numpy.asarray(M.T)[0,:].

From a technical point of view they're completely different. <datalist> is an abstract container of options for other elements. In your case you've used it with <input type="text" but you can also use it with ranges, colors, dates etc. http://demo.agektmr.com/datalist/

If using it with text input, as a type of autocomplete, then the question really is: Is it better to use a free-form text input, or a predetermined list of options? In that case I think the answer is a bit more obvious.

If we focus on the use of <datalist> as a list of options for a text field then here are some specific differences between that and a select box:

• A <datalist> fed text box has a single string for both display label and submit. A select box can have a different submit value vs. display label <option value='ie'>Internet Explorer</option>.
• A <datalist> fed text box does not support the <optgroup> tag to organize the display.
• You can not restrict a user to the list of options in a <datalist> like you can with a <select>.
• The onchange event works differently. On a <select> element, the onchange event is fired immediately upon change, whereas with <input type="text" the event is fired after the element loses focus or the user presses enter.
• <datalist> has really spotty support across browsers. The way to show all available options is inconsistent, and things only get worse from there.

The last point is really the big one in my opinion. Since you will HAVE to have a more universal autocomplete fallback, then there is almost no reason to go through the trouble of configuring a <datalist>. Plus any decent autocomplete pluging will allow for ways to style the display of your options, which <datalist> does not do. If <datalist> accepted <li> elements that you could manipulate however you want, it would have been really great! But NO.

Also insofar as i can tell, the <datalist> search is an exact match from the beginning of the string. So if you had <option value="internet explorer"> and you searched for 'explorer' you would get no results. Most autocomplete plugins will search anywhere in the text.

I've only used <datalist> as a quick and lazy convenience helper for some internal pages where I know with a 100% certainty that the users have the latest Chrome or Firefox, and will not try to submit bogus values. For any other case, it's hard to recommend the use of <datalist> due to very poor browser support.

    //create TreeMap instance
    TreeMap treeMap = new TreeMap();

    //add key value pairs to TreeMap
    treeMap.put("1","One");
    treeMap.put("2","Two");
    treeMap.put("3","Three");

    /*
      get Collection of values contained in TreeMap using
      Collection values()        
    */
    Collection c = treeMap.values();

    //obtain an Iterator for Collection
    Iterator itr = c.iterator();

    //iterate through TreeMap values iterator
    while(itr.hasNext())
      System.out.println(itr.next());

or:

   for (Map.Entry<K,V> entry : treeMap.entrySet()) {
        V value = entry.getValue();
        K key = entry.getKey();
   }

or:

   // Use iterator to display the keys and associated values
   System.out.println("Map Values Before: ");
   Set keys = map.keySet();
   for (Iterator i = keys.iterator(); i.hasNext();) {
     Integer key = (Integer) i.next();
     String value = (String) map.get(key);
     System.out.println(key + " = " + value);
   }

The date function would be defined something like this:

function date($format, $timestamp = null)
{
    if ($timestamp === null) {
        $timestamp = time();
    }

    // Format the timestamp according to $format
}

Usually, you would put the default value like this:

function foo($required, $optional = 42)
{
    // This function can be passed one or more arguments
}

However, only literals are valid default arguments, which is why I used null as default argument in the first example, not $timestamp = time(), and combined it with a null check. Literals include arrays (array() or []), booleans, numbers, strings, and null.

Try adding parentheses around the row in table1 e.g.

DELETE 
  FROM table1
 WHERE (stn, year(datum)) IN (SELECT stn, jaar FROM table2);

The above is Standard SQL-92 code. If that doesn't work, it could be that your SQL product of choice doesn't support it.

Here's another Standard SQL approach that is more widely implemented among vendors e.g. tested on SQL Server 2008:

MERGE INTO table1 AS t1
   USING table2 AS s1
      ON t1.stn = s1.stn
         AND s1.jaar = YEAR(t1.datum)
WHEN MATCHED THEN DELETE;

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?

You can run OpenSSH on Cygwin, and even install it as a Windows service.

I once used it this way to easily add backups of a Unix system - it would rsync a bunch of files onto the Windows server, and the Windows server had full tape backups.

No- you can definitely handle more than that.

Its important to remember that deep deep down, assuming you are running a single core machine, the CPU really only runs one instruction* at a time.

Namely, the CPU can only execute a very limited set of instructions, and it can't execute more than one instruction per clock tick (many instructions even take more than 1 tick).

Therefore, most concurrency we talk about in computer science is software concurrency. In other words, there are layers of software implementation that abstract the bottom level CPU from us and make us think we are running code concurrently.

These "things" can be processes, which are units of code that get run concurrently in the sense that each process thinks its running in its own world with its own, non-shared memory.

Another example is threads, which are units of code inside processes that allow concurrency as well.

The reason your 4 worker processes will be able to handle more than 4 requests is that they will fire off threads to handle more and more requests.

The actual request limit depends on HTTP server chosen, I/O, OS, hardware, network connection etc.

Good luck!

*instructions are the very basic commands the CPU can run. examples - add two numbers, jump from one instruction to another

All of the information you are looking for can be found here and here (thanks Reed Copsey):

From the first link:

Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.

...

The access level for class members and struct members, including nested classes and structs, is private by default.

...

interfaces default to internal access.

...

Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.

From the second link:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

And for nested types:

Members of    Default member accessibility
----------    ----------------------------
enum          public
class         private
interface     public
struct        private

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:

(the difference between altering the way version history is recorded)
