The following is a proposed solution for the OP's specific problem (extracting the 2nd word of a string), but it should be noted that, as mc0e's answer states, actually extracting regex matches is not supported out-of-the-box in MySQL. If you really need this, then your choices are basically to 1) do it in post-processing on the client, or 2) install a MySQL extension to support it.

BenWells has it very almost correct. Working from his code, here's a slightly adjusted version:

SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
)

As a working example, I used:

SELECT SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
) as string
FROM (SELECT 'THIS IS A TEST' AS sentence) temp

This successfully extracts the word IS

These snippets all perform exactly the same thing:

element.on('click', function () { ... });
element.bind('click', function () { ... });
element.click(function () { ... });

However, they are very different from these, which all perform the same thing:

element.on('click', 'selector', function () { ... });
element.delegate('click', 'selector', function () { ... });
$('selector').live('click', function () { ... });

The second set of event handlers use event delegation and will work for dynamically added elements. Event handlers that use delegation are also much more performant. The first set will not work for dynamically added elements, and are much worse for performance.

jQuery's on() function does not introduce any new functionality that did not already exist, it is just an attempt to standardize event handling in jQuery (you no longer have to decide between live, bind, or delegate).

We can combine the DUAL and NOT EXISTS to archive your requirement:

INSERT INTO schema.myFoo ( 
    primary_key, value1, value2
) 
SELECT
    'bar', 'baz', 'bat' 
FROM DUAL
WHERE NOT EXISTS (
    SELECT 1 
    FROM schema.myFoo
    WHERE primary_key = 'bar'
);

You can't change a Font once it's created - so you need to create a new one:

  mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);

<select name="foo" id="foo">
 <option value="1">a</option>
 <option value="2">b</option>
 <option value="3">c</option>
  </select>
  <input type="button" id="button" value="Button" />
  });
  <script> ("#foo").val() </script>

which returns 1 if you have selected a and so on..

Above answers clearly answer the question but I want to provide another alternative - A different view/approach to solve the similar problem.

You can also use browser extension to remove X-Content-Type-Options response header for raw.githubusercontent.com files. There are couple of browser extensions to modify response headers.

1. Requestly: Chrome + Firefox
2. Modify Headers: Firefox

If you use Requestly, I can suggest two solutions

Solution 1: Use Modify Headers Rule and remove the response header

Steps

1. Install Requestly from http://www.requestly.in
2. Go to Rules Page
3. Click on Add Icon to create a rule
4. Select Modify Headers
5. Give a Name and Descripton
6. Select Remove -> Response -> X-Content-Type-Options
7. In Source field, enter Url -> Contains -> raw.githubusercontent.com

Solution 2: Use Replace host Rule

1. Install Requestly from http://www.requestly.in
2. Go to Rules Page
3. Click on Add Icon to create a rule
4. Replace raw.githubusercontent.com with rawgit.com

Check this screenshot for more details

How to test

We created a simple JS Fiddle to test out if we can use raw github files as scripts in our code. Here is the Fiddle with the following code

<center id="msg"></center>

<script src="https://raw.githubusercontent.com/sachinjain024/practicebook/master/web-extensions-master/storage/background.js"></script>
<script>
try {
  if (typeof BG.Methods !== 'undefoned') {
    document.getElementById('msg').innerHTML = 'Script evaluated successfully!';
  }
} catch (e) {
  document.getElementById('msg').innerHTML = 'Problem evaluating script';
}
</script>

If you see Script evaluated successfully!, It means you are able to use raw github file in your code Otherwise Problem evaluating script indicates that there is some problem while executing script from raw github source.

I also wrote an article on Requestly blog about this. Please refer it for more details.

Hope it helps!!

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.

var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

try this type of format:

SELECT to_char(sysdate,'dd-mm-rrrr') FROM dual

1. Open your Java source code document and navigate to the JTable object you have created inside of your Swing class.

2. Create a new TableModel object that holds a DatePickerTable. You must create the DatePickerTable with a range of date values in MMDDYYYY format. The first value is the begin date and the last is the end date. In code, this looks like:

   TableModel datePicker = new DatePickerTable("01011999","12302000");
   

3. Set the display interval in the datePicker object. By default each day is displayed, but you may set a regular interval. To set a 15-day interval between date options, use this code:

   datePicker.interval = 15;
   

4. Attach your table model into your JTable:

   JTable newtable = new JTable (datePicker);
   

   Your Java application now has a drop-down date selection dialog.

Based on Pumbaa80's answer I have modified the code to use the console.log colours (working on Chrome for sure) and not HTML. Output can be seen inside console. You can edit the _variables inside the function adding some more styling.

function JSONstringify(json) {
    if (typeof json != 'string') {
        json = JSON.stringify(json, undefined, '\t');
    }

    var 
        arr = [],
        _string = 'color:green',
        _number = 'color:darkorange',
        _boolean = 'color:blue',
        _null = 'color:magenta',
        _key = 'color:red';

    json = json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) {
        var style = _number;
        if (/^"/.test(match)) {
            if (/:$/.test(match)) {
                style = _key;
            } else {
                style = _string;
            }
        } else if (/true|false/.test(match)) {
            style = _boolean;
        } else if (/null/.test(match)) {
            style = _null;
        }
        arr.push(style);
        arr.push('');
        return '%c' + match + '%c';
    });

    arr.unshift(json);

    console.log.apply(console, arr);
}

Here is a bookmarklet you can use:

javascript:function JSONstringify(json) {if (typeof json != 'string') {json = JSON.stringify(json, undefined, '\t');}var arr = [],_string = 'color:green',_number = 'color:darkorange',_boolean = 'color:blue',_null = 'color:magenta',_key = 'color:red';json = json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) {var style = _number;if (/^"/.test(match)) {if (/:$/.test(match)) {style = _key;} else {style = _string;}} else if (/true|false/.test(match)) {style = _boolean;} else if (/null/.test(match)) {style = _null;}arr.push(style);arr.push('');return '%c' + match + '%c';});arr.unshift(json);console.log.apply(console, arr);};void(0);

Usage:

var obj = {a:1, 'b':'foo', c:[false,null, {d:{e:1.3e5}}]};
JSONstringify(obj);

Edit: I just tried to escape the % symbol with this line, after the variables declaration:

json = json.replace(/%/g, '%%');

But I find out that Chrome is not supporting % escaping in the console. Strange... Maybe this will work in the future.

Cheers!

Try Dividing /1

select if(value/1>0 or value=0,'its a number', 'its not a number') from table

A Subquery in the Select clause, as in your case, is also known as a Scalar Subquery, which means that it's a form of expression. Meaning that it can only return one value.

I'm afraid you can't return multiple columns from a single Scalar Subquery, no.

Here's more about Oracle Scalar Subqueries:

http://docs.oracle.com/cd/B19306_01/server.102/b14200/expressions010.htm#i1033549

I had a list of lists of equal length. Even then Ignacio Vazquez-Abrams's answer didn't work out for me. I got a 1-D numpy array whose elements are lists. If you faced the same problem, you can use the below method

Use numpy.vstack

import numpy as np

np_array = np.empty((0,4), dtype='float')
for i in range(10)
     row_data = ...   # get row_data as list
     np_array = np.vstack((np_array, np.array(row_data)))

Try browser.execute_script instead of selenium.GetEval.

See this answer for example.

If you want to do multiple $ne then do

db.users.find({name : {$nin : ["mary", "dick", "jane"]}})

It depends where you put this initialisation.

If the array is static as in

char array[100] = {0};

int main(void)
{
...
}

then it is the compiler that reserves the 100 0 bytes in the data segement of the program. In this case you could have omitted the initialiser.

If your array is auto, then it is another story.

int foo(void)
{
char array[100] = {0};
...
}

In this case at every call of the function foo you will have a hidden memset.

The code above is equivalent to

int foo(void)
{ 
char array[100];

memset(array, 0, sizeof(array));
....
}

and if you omit the initializer your array will contain random data (the data of the stack).

If your local array is declared static like in

int foo(void)
{ 
static char array[100] = {0};
...
}

then it is technically the same case as the first one.

I found that an answer to this issue when dealing with math is that the operator on the left hand side must be the variable you are trying to change. The logic cannot come first.

coin1 + coin2 + coin3 = coinTotal; // Wrong

coinTotal = coin1 + coin2 + coin3; // Right

This isn't a direct answer to your question but it might be helpful to future people who google the same thing I googled.

a.hover:hover {

I'll add vote for Eigen: I ported a lot of code (3D geometry, linear algebra and differential equations) from different libraries to this one - improving both performance and code readability in almost all cases.

One advantage that wasn't mentioned: it's very easy to use SSE with Eigen, which significantly improves performance of 2D-3D operations (where everything can be padded to 128 bits).

I had the similar problem. It was a maven project with the following snippet of pom.xml.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <release>9</release>
            </configuration>
        </plugin>
        </plugins>
    </build>

I had to change the following.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <release>11</release>
            </configuration>
        </plugin>
        </plugins>
    </build>

If you have already installed JDK 11 and working with java 9 or java 10 as maven compiler, eclipse can not detect. Hence change the release to 11 or the actual installed version of JDK.

Based on Dirk Stöcker's answer, here's a neat wrapper function for Python 3's print function. Use it just like you would use print.

As an added bonus, compared to the other answers, this won't print your text as a bytearray ('b"content"'), but as normal strings ('content'), because of the last decode step.

def uprint(*objects, sep=' ', end='\n', file=sys.stdout):
    enc = file.encoding
    if enc == 'UTF-8':
        print(*objects, sep=sep, end=end, file=file)
    else:
        f = lambda obj: str(obj).encode(enc, errors='backslashreplace').decode(enc)
        print(*map(f, objects), sep=sep, end=end, file=file)

uprint('foo')
uprint(u'Antonín Dvorák')
uprint('foo', 'bar', u'Antonín Dvorák')

there is no way to specifically target an element with php, you can either embed the php code between a div tag or use jquery which would be longer.

CASE is more like a switch statement. It has two syntaxes you can use. The first lets you use any compare statements you want:

CASE 
    WHEN user_role = 'Manager' then 4
    WHEN user_name = 'Tom' then 27
    WHEN columnA <> columnB then 99
    ELSE -1 --unknown
END

The second style is for when you are only examining one value, and is a little more succinct:

CASE user_role
    WHEN 'Manager' then 4
    WHEN 'Part Time' then 7
    ELSE -1 --unknown
END

If you're using jQuery {UI} (which everyone should be using :-) ), you can use .change() with a hidden <input/> element.

double[,] is a 2d array (matrix) while double[][] is an array of arrays (jagged arrays) and the syntax is:

double[][] ServicePoint = new double[10][];

This worked for me:

p { margin-left: -2em; 
 text-indent: 2em 
 }

In Ubuntu 18.04, below are the steps that I followed.

python3 -m pip install --upgrade pip

For some reason you will be getting an error, and that be fixed by making bash forget the wrongly referenced locations using the following command.

hash -r pip

If you are using maven, try adding Lombok path to maven-compiler-plugin list of annotation processor as shown below.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.mapstruct</groupId>
                        <artifactId>mapstruct-processor</artifactId>
                        <version>1.3.0.Final</version>
                    </path>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.18.10</version>
                    </path>
                </annotationProcessorPaths>
            </configuration>
        </plugin>

Change the version as per your version of Lombok. Other than that ensure you have done the following

• installed the Lombok plugin for Intellij.
• Enabled annotation processing for your project under File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processor. For me both, Obtain processors from project classpath and Processor path is working. So not sure what will work for you, but try whichever works.

And rather than shooting in the dark for hours. Reading a little bit how annotation processors work and are used by compiler may help. so have quick read below.

http://hannesdorfmann.com/annotation-processing/annotationprocessing101

Instead of filtering by URL, you can also filter by HTTP header. This configuration will work for any web applications that use websockets, also if they are not using socket.io:

<VirtualHost *:80>
  ServerName www.domain2.com

  RewriteEngine On
  RewriteCond %{HTTP:Upgrade} =websocket [NC]
  RewriteRule /(.*)           ws://localhost:3001/$1 [P,L]
  RewriteCond %{HTTP:Upgrade} !=websocket [NC]
  RewriteRule /(.*)           http://localhost:3001/$1 [P,L]

  ProxyPassReverse / http://localhost:3001/
</VirtualHost>

BindingProvider.USERNAME_PROPERTY and BindingProvider.PASSWORD_PROPERTY are matching HTTP Basic Authentication mechanism that enable authentication process at the HTTP level and not at the application nor servlet level.

Basically, only the HTTP server will know the username and the password (and eventually application according to HTTP/application server specification, such with Apache/PHP). With Tomcat/Java, add a login config BASIC in your web.xml and appropriate security-constraint/security-roles (roles that will be later associated to users/groups of real users).

<login-config>
    <auth-method>BASIC</auth-method>
    <realm-name>YourRealm</realm-name>
</login-config>

Then, connect the realm at the HTTP server (or application server) level with the appropriate user repository. For tomcat you may look at JAASRealm, JDBCRealm or DataSourceRealm that may suit your needs.

Solution with Jquery

$(window).resize(function () {
    var width = $("#map").width();
    $("#map").height(width * 1.72);
});

If someone is here as in 2016 for the answer, use .fail() for error handling as .error() is deprecated as of jQuery 3.0

$.ajax( "example.php" )
  .done(function() {
    alert( "success" );
  })
  .fail(function(jqXHR, textStatus, errorThrown) {
    //handle error here
  })

I hope it helps

public class SumOfSubSet {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        int a[] = {1,2};
        int sum=0;
        if(a.length<=0) {
            System.out.println(sum);
        }else {
        for(int i=0;i<a.length;i++) {
            sum=sum+a[i];
            for(int j=i+1;j<a.length;j++) {
                sum=sum+a[i]+a[j];
            }
        }
        System.out.println(sum);

        }


    }

You don't need to run any docker commands as sudo when you're using boot2docker as every command passed into the boot2docker VM runs as root by default.

You're seeing the error when you're running as sudo because sudo doesn't have the DOCKER_HOST env set, only your user does.

You can confirm this by doing a:

$ env

Then a

$ sudo env

And looking for DOCKER_HOST in each output.

As for having a docker file that runs your script, something like this might work for you:

Dockerfile

FROM busybox

# Copy your script into the docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh

# Run your script
CMD /usr/local/bin/script.sh

Then you can run:

docker build -t your-image-name:your-tag .

This will build your docker image, which you can see by doing a:

docker images

Then, to run your container, you can do a:

docker run your-image-name:your-tag

This run command will start a container from the image you created with your Dockerfile and your build command and then it will finish once your script.sh has finished executing.

$('input[type=submit]').on('click', validate);


function validate() {
  var password1 = $("#password1").val();
  var password2 = $("#password2").val();

    if(password1 == password2) {
       $("#validate-status").text("valid");        
    }
    else {
        $("#validate-status").text("invalid");  
    } 
}

Logic is to check on keyup if the value in both fields match or not.

• More details here: Checking password match while typing

Just an extra info, if you are using DB:

DB::table('test')->where('id', '>', 0)->pluck('id')->toArray();

And if using Eloquent model:

test::where('id', '>', 0)->lists('id')->toArray();

According to Django documentation, inline formsets are for this purpose: "Inline formsets is a small abstraction layer on top of model formsets. These simplify the case of working with related objects via a foreign key".

See https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#inline-formsets

I use prop attribute for unchecked the checkbox when errors occur. You don't need to use remove property for unchecked your checkbox.

$('input#IDName').prop('checked', false);

It is working fine for me. Hope it will work for you also.

To successfully stop MySQL Service on Windows

1. Check on services the name of the service for MySQL
2. Run as administrator : net stop [MySQL Service name]

The most readable way is

x = 10 if a > b else 11

but you can use and and or, too:

x = a > b and 10 or 11

The "Zen of Python" says that "readability counts", though, so go for the first way.

Also, the and-or trick will fail if you put a variable instead of 10 and it evaluates to False.

However, if more than the assignment depends on this condition, it will be more readable to write it as you have:

if A[i] > B[j]:
  x = A[i]
  i += 1
else:
  x = A[j]
  j += 1

unless you put i and j in a container. But if you show us why you need it, it may well turn out that you don't.

I don't think it's enough merely to get the response. I think you need to read it (get the entity and read it via EntityUtils.consume()).

You can always split a commit, From the manual

• Start an interactive rebase with git rebase -i commit^, where commit is the commit you want to split. In fact, any commit range will do, as long as it contains that commit.
• Mark the commit you want to split with the action "edit".
• When it comes to editing that commit, execute git reset HEAD^. The effect is that the HEAD is rewound by one, and the index follows suit. However, the working tree stays the same.
• Now add the changes to the index that you want to have in the first commit. You can use git add (possibly interactively) or git-gui (or both) to do that.
• Commit the now-current index with whatever commit message is appropriate now.
• Repeat the last two steps until your working tree is clean.
• Continue the rebase with git rebase --continue.

You can use the first selector.

var header = $('.header:first')

Once I had written a program that handle the short (-h), long (--help) and non-option arguments in batch file. This techniques includes:

• non-option arguments followed by a option arguments.

• shift operator for those options that have no argument like '--help'.

• two time shift operator for those options that require an argument.

• loop through a label for processing all command line arguments.

• Exit script and stop processing for those options that no need to require further action like '--help'.

• Wrote help functions for user guidiness

Here is my code.

set WORKSPACE=
set CFLAGS=
set LIB_INSTALL=true
set PREFIX=lib
set PROGRAM=install_boards

As we recently posted on the React blog, in the vast majority of cases you don't need getDerivedStateFromProps at all.

If you just want to compute some derived data, either:

1. Do it right inside render
2. Or, if re-calculating it is expensive, use a memoization helper like memoize-one.

Here's the simplest "after" example:

import memoize from "memoize-one";

class ExampleComponent extends React.Component {
  getDerivedData = memoize(computeDerivedState);

  render() {
    const derivedData = this.getDerivedData(this.props.someValue);
    // ...
  }
}

@ManyToMany associations

Most often, you will need to use @JoinTable annotation to specify the mapping of a many-to-many table relationship:

• the name of the link table and
• the two Foreign Key columns

So, assuming you have the following database tables:

In the Post entity, you would map this relationship, like this:

@ManyToMany(cascade = {
    CascadeType.PERSIST,
    CascadeType.MERGE
})
@JoinTable(
    name = "post_tag",
    joinColumns = @JoinColumn(name = "post_id"),
    inverseJoinColumns = @JoinColumn(name = "tag_id")
)
private List<Tag> tags = new ArrayList<>();

The @JoinTable annotation is used to specify the table name via the name attribute, as well as the Foreign Key column that references the post table (e.g., joinColumns) and the Foreign Key column in the post_tag link table that references the Tag entity via the inverseJoinColumns attribute.

Notice that the cascade attribute of the @ManyToMany annotation is set to PERSIST and MERGE only because cascading REMOVE is a bad idea since we the DELETE statement will be issued for the other parent record, tag in our case, not to the post_tag record.

Unidirectional @OneToMany associations

The unidirectional @OneToMany associations, that lack a @JoinColumn mapping, behave like many-to-many table relationships, rather than one-to-many.

So, assuming you have the following entity mappings:

@Entity(name = "Post")
@Table(name = "post")
public class Post {
 
    @Id
    @GeneratedValue
    private Long id;
 
    private String title;
 
    @OneToMany(
        cascade = CascadeType.ALL,
        orphanRemoval = true
    )
    private List<PostComment> comments = new ArrayList<>();
 
    //Constructors, getters and setters removed for brevity
}
 
@Entity(name = "PostComment")
@Table(name = "post_comment")
public class PostComment {
 
    @Id
    @GeneratedValue
    private Long id;
 
    private String review;
 
    //Constructors, getters and setters removed for brevity
}

Hibernate will assume the following database schema for the above entity mapping:

As already explained, the unidirectional @OneToMany JPA mapping behaves like a many-to-many association.

To customize the link table, you can also use the @JoinTable annotation:

@OneToMany(
    cascade = CascadeType.ALL,
    orphanRemoval = true
)
@JoinTable(
    name = "post_comment_ref",
    joinColumns = @JoinColumn(name = "post_id"),
    inverseJoinColumns = @JoinColumn(name = "post_comment_id")
)
private List<PostComment> comments = new ArrayList<>();

And now, the link table is going to be called post_comment_ref and the Foreign Key columns will be post_id, for the post table, and post_comment_id, for the post_comment table.

Unidirectional @OneToMany associations are not efficient, so you are better off using bidirectional @OneToMany associations or just the @ManyToOne side.

To sandwich an my element between the modal screen and a dialog, I need to lift my element above the modal-screen, and then lift the dialog above my element.

I had a small success by doing the following after creating the dialog on element $dlg.

$dlg.closest('.ui-dialog').css('zIndex',adjustment);

Since each dialog has a different starting z-index (they incrementally get larger) I make adjustment a string with a boost value, like this:

const adjustment = "+=99";

However, jQuery just keeps increasing the zIndex value on the modal screen, so by the second dialog, the sandwich no longer worked. I gave up on ui-dialog "modal", made it "false", and just created my own modal. It imitates jQueryUI exactly. Here it is:

CoverAll = {};
CoverAll.modalDiv = null;

CoverAll.modalCloak = function(zIndex) {
  var div = CoverAll.modalDiv;
  if(!CoverAll.modalDiv) {
    div = CoverAll.modalDiv = document.createElement('div');
    div.style.background = '#aaaaaa';
    div.style.opacity    = '0.3';
    div.style.position   = 'fixed';
    div.style.top        = '0';
    div.style.left       = '0';
    div.style.width      = '100%';
    div.style.height     = '100%';
  }
  if(!div.parentElement) {
    document.body.appendChild(div);
  }
  if(zIndex == null)
    zIndex = 100;
  div.style.zIndex  = zIndex;
  return div;
}

CoverAll.modalUncloak = function() {
  var div = CoverAll.modalDiv;
  if(div && div.parentElement) {
    document.body.removeChild(div);
  }
  return div;
}

I tried serkan's solution, it found java 7's location on OS X Mavericks. it is resided in "/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/" but to make it the default JDK I had to set JAVA_HOME system variable in .bash_profile in home directory to "/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/" so its up and running now thanks to serkan's idea

You can use the null-coalescing operator: x ?? something, where something is a boolean value that you want to use if x is null.

Example:

bool? myBool = null;
bool newBool = myBool ?? false;

newBool will be false.

I suppose that the array size if a computed value.

int size = ComputeArraySize();

// Then

String[] array = new String[size]; 

Further to @pmg's answer, note that you can do both operations in one statement:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;

This will likely work as expected but behavior is undefined in C standard.

The only problem with threads is accessing the same object from different threads without synchronization.

If each function only uses parameters for reading and local variables, they don't need any synchronization to be thread-safe.

I found your question while searching for information with SQLite and Java. Just thought I'd add my answer which I also posted on my blog.

I have been coding in Java for a while now. I have also known about SQLite but never used it… Well I have used it through other applications but never in an app that I coded. So I needed it for a project this week and it's so simple use!

I found a Java JDBC driver for SQLite. Just add the JAR file to your classpath and import java.sql.*

His test app will create a database file, send some SQL commands to create a table, store some data in the table, and read it back and display on console. It will create the test.db file in the root directory of the project. You can run this example with java -cp .:sqlitejdbc-v056.jar Test.

package com.rungeek.sqlite;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;

public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn.prepareStatement(
            "insert into people values (?, ?);");

        prep.setString(1, "Gandhi");
        prep.setString(2, "politics");
        prep.addBatch();
        prep.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.addBatch();
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");
        prep.addBatch();

        conn.setAutoCommit(false);
        prep.executeBatch();
        conn.setAutoCommit(true);

        ResultSet rs = stat.executeQuery("select * from people;");
        while (rs.next()) {
            System.out.println("name = " + rs.getString("name"));
            System.out.println("job = " + rs.getString("occupation"));
        }
        rs.close();
        conn.close();
    }
  }

This way we can do this with minimal changes :)

It seems that some apps won't read symlinked /etc/hosts (on macOS at least), you need to hardlink it.

ln /path/to/hosts_file /etc/hosts

Setting the index name can also be accomplished at creation:

pd.DataFrame(data={'age': [10,20,30], 'height': [100, 170, 175]}, index=pd.Series(['a', 'b', 'c'], name='Tag'))

Outside of the performance (non)issues, I think the biggest failing of cursors is they are painful to debug. Especially compared to code in most client applications where debugging tends to be comparatively easy and language features tend to be much easier. In fact, I contend that nearly anything one is doing in SQL with a cursor should probably be happening in the client app in the first place.

To enable use bind() method

$("#id").bind("click",eventhandler);

call this handler

 function  eventhandler(){
      alert("Bind click")
    }

To disable click useunbind()

$("#id").unbind("click");

Okay, let's re-iterate...

The actual question (and an excellent one at that)

"What does 'run as admin' do that being a member of the administrators group does not?"

(Answer)1. It allows you to call on administrator rights while under a user session.

Note: The question is wrongly put; one is a command and the other is a group object to apply policies.

Open a command prompt and type runas /?.

This will list all the switches the runas command line can use.

As for the Administrators Group this is based on GPEDIT or SECPOL and whether or not a Domain administrator is present or not or a network is present or not.

Usually these things will apply restrictions on computers that the administrators group is not affected by.

The question should be

What does runas admin do that run as user does not?

OR

What does the Administrator group do that a customized user group can't?

You are mixing apples and oranges.

This can also happen when the log file is restricted in size.

Right click database in Object Explorer

COM interop. Especially IUnknown. It was designed specially for it.

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

I'm no expert in map-reading / navigation and so on but surely 'directions' are absolute and not relative or in reality, they are relative to N or S which themselves are fixed/absolute.

Example: Suppose an imaginary line drawn between you and your destination corresponds with 'absolute' SE (a bearing of 135 degrees relative to magnetic N). Now suppose your phone is pointing NW - if you draw an imaginary line from an imaginary object on the horizon to your destination, it will pass through your location and have an angle of 180 degrees. Now 180 degrees in the sense of a compass actually refers to S but the destination is not 'due S' of the imaginary object your phone is pointing at and, moreover, if you travelled to that imaginary point, your destination would still be SE of where you moved to.

In reality, the 180 degree line actually tells you the destination is 'behind you' relative to the way the phone (and presumably you) are pointing.

Having said that, however, if calculating the angle of a line from the imaginary point to your destination (passing through your location) in order to draw a pointer towards your destination is what you want...simply subtract the (absolute) bearing of the destination from the absolute bearing of the imaginary object and ignore a negation (if present). e.g., NW - SE is 315 - 135 = 180 so draw the pointer to point at the bottom of the screen indicating 'behind you'.

EDIT: I got the Maths slightly wrong...subtract the smaller of the bearings from the larger then subtract the result from 360 to get the angle in which to draw the pointer on the screen.

Answer to 1: ArrayList uses an array under the hood. Accessing a member of an ArrayList object is as simple as accessing the array at the provided index, assuming the index is within the bounds of the backing array. A LinkedList has to iterate through its members to get to the nth element. That's O(n) for a LinkedList, versus O(1) for ArrayList.

How about:

^([A-Za-z]|[0-9]|_)+$

...if you want to be explicit, or:

^\w+$

...if you prefer concise (Perl syntax).

Press Ctrl-a then : and then type

scrollback 10000

to get a 10000 line buffer, for example.

You can also set the default number of scrollback lines by adding

defscrollback 10000

to your ~/.screenrc file.

To scroll (if your terminal doesn't allow you to by default), press Ctrl-a ESC and then scroll (with the usual Ctrl-f for next page or Ctrl-a for previous page, or just with your mouse wheel / two-fingers). To exit the scrolling mode, just press ESC.

Another tip: Ctrl-a i shows your current buffer setting.

Have look at WebLookAndFeel at https://github.com/mgarin/weblaf/

WebTextField txtName = new com.alee.laf.text.WebTextField();

txtName.setHideInputPromptOnFocus(false);

txtName.setInputPrompt("Name");

txtName.setInputPromptFont(new java.awt.Font("Ubuntu", 0, 18));

txtName.setInputPromptForeground(new java.awt.Color(102, 102, 102));

txtName.setInputPromptPosition(0);

If a credit card is already added to a PayPal account then it won't let you use that card to process directly with Payments Advanced. The system expects buyers to login to PayPal and just choose that credit card as their funding source if they want to pay with it.

As for testing on the sandbox, I've always used old, expired credit cards I have laying around and they seem to work fine for me.

You could always try the ones starting on page 87 of the PayFlow documentation, too. They should work.

I used the following approach for determining the frame of the keyboard in iOS 7.1.

In the init method of my view controller, I registered for the UIKeyboardDidShowNotification:

NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
[center addObserver:self selector:@selector(keyboardOnScreen:) name:UIKeyboardDidShowNotification object:nil];

Then, I used the following code in keyboardOnScreen: to gain access to the frame of the keyboard. This code gets the userInfo dictionary from the notification and then accesses the NSValue associated with UIKeyboardFrameEndUserInfoKey. You can then access the CGRect and convert it to the coordinates of the view of your view controller. From there, you can perform any calculations you need based on that frame.

-(void)keyboardOnScreen:(NSNotification *)notification 
 {
        NSDictionary *info  = notification.userInfo;
        NSValue      *value = info[UIKeyboardFrameEndUserInfoKey];

        CGRect rawFrame      = [value CGRectValue];
        CGRect keyboardFrame = [self.view convertRect:rawFrame fromView:nil];

        NSLog(@"keyboardFrame: %@", NSStringFromCGRect(keyboardFrame));
 }

Swift

And the equivalent implementation with Swift:

NotificationCenter.default.addObserver(self, selector: #selector(keyboardDidShow), name: UIResponder.keyboardDidShowNotification, object: nil)


@objc
func keyboardDidShow(notification: Notification) {
    guard let info = notification.userInfo else { return }
    guard let frameInfo = info[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue else { return }
    let keyboardFrame = frameInfo.cgRectValue
    print("keyboardFrame: \(keyboardFrame)")
}

Read the doc:

In general, php://input should be used instead of $HTTP_RAW_POST_DATA.

If you have ever used the Requests module for python before, I recently found out that the developer created a new module called Requests-HTML which now also has the ability to render JavaScript.

You can also visit https://html.python-requests.org/ to learn more about this module, or if your only interested about rendering JavaScript then you can visit https://html.python-requests.org/?#javascript-support to directly learn how to use the module to render JavaScript using Python.

Essentially, Once you correctly install the Requests-HTML module, the following example, which is shown on the above link, shows how you can use this module to scrape a website and render JavaScript contained within the website:

from requests_html import HTMLSession
session = HTMLSession()

r = session.get('http://python-requests.org/')

r.html.render()

I recently learnt about this from a YouTube video. Click Here! to watch the YouTube video, which demonstrates how the module works.

First, you don't need the .class files if they are compiled from your .java classes.

To import your files, you need to create an empty Java project. They you either import them one by one (New -> File -> Advanced -> Link file) or directly copy them into their corresponding folder/package and refresh the project.

This code generates some SQL which can achieve this on every table and column in the database:

SELECT
   'UPDATE ['+T.TABLE_SCHEMA+'].[' + T.TABLE_NAME + '] SET [' + COLUMN_NAME + '] = NULL 
   WHERE [' + COLUMN_NAME + '] = '''''
FROM 
    INFORMATION_SCHEMA.columns C
INNER JOIN
    INFORMATION_SCHEMA.TABLES T ON C.TABLE_NAME=T.TABLE_NAME AND C.TABLE_SCHEMA=T.TABLE_SCHEMA
WHERE 
    DATA_TYPE IN ('char','nchar','varchar','nvarchar')
AND C.IS_NULLABLE='YES'
AND T.TABLE_TYPE='BASE TABLE'

This post asked a similar question and used LINQ to solve it, maybe it will help you out too.

string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
int[] ia = s1.Split(';').Select(n => Convert.ToInt32(n)).ToArray();

Your regular expression should look like:

/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$/

Here is an explanation:

/^
  (?=.*\d)          // should contain at least one digit
  (?=.*[a-z])       // should contain at least one lower case
  (?=.*[A-Z])       // should contain at least one upper case
  [a-zA-Z0-9]{8,}   // should contain at least 8 from the mentioned characters
$/

input element, of type file

<input id="fileInput" type="file" />

On your input change use the FileReader object and read your input file property:

$('#fileInput').on('change', function () {
    var fileReader = new FileReader();
    fileReader.onload = function () {
      var data = fileReader.result;  // data <-- in this var you have the file data in Base64 format
    };
    fileReader.readAsDataURL($('#fileInput').prop('files')[0]);
});

FileReader will load your file and in fileReader.result you have the file data in Base64 format (also the file content-type (MIME), text/plain, image/jpg, etc)

Just add another join:

SELECT dashboard_data.headline,
       dashboard_data.message,
       dashboard_messages.image_id,
       images.filename 
FROM dashboard_data 
    INNER JOIN dashboard_messages
            ON dashboard_message_id = dashboard_messages.id 
    INNER JOIN images
            ON dashboard_messages.image_id = images.image_id

I created dummy sample for Google Maps v2 Android with Kotlin and AndroidX

    setContentView(R.layout.activity_main)

    with(mapView) {
        // Initialise the MapView
        onCreate(null)
        // Set the map ready callback to receive the GoogleMap object
        getMapAsync{
            MapsInitializer.initialize(applicationContext)

If the file that this script lives in is executable, the hash-bang (#!) tells the operating system what interpreter to use to run the script. In this case it's /bin/sh, for example.

There's a Wikipedia article about it for more information.

The multiline flag tells regex to match the pattern to each line as opposed to the entire string for your purposes a wild card will suffice.

Isn't just as simple as Strings are made up of characters arrays. I look at strings as character arrays[]. Therefore they are on the heap because the reference memory location is stored on the stack and points to the beginning of the array's memory location on the heap. The string size is not known before it is allocated ...perfect for the heap.

That is why a string is really immutable because when you change it even if it is of the same size the compiler doesn't know that and has to allocate a new array and assign characters to the positions in the array. It makes sense if you think of strings as a way that languages protect you from having to allocate memory on the fly (read C like programming)

I had the same problem. Files defined in .gitingore where listed as untracked files when running git status.

The reason was that the .gitignore file was saved in UTF-16LE encoding, and not in UTF8 encoding.

After changing the encoding of the .gitignore file to UTF8 it worked for me.

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction() but instead wrap your code in DB::beginTransaction and DB::commit/DB::rollback():

DB::beginTransaction();

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit();
    // all good
} catch (\Exception $e) {
    DB::rollback();
    // something went wrong
}

See the transaction docs.

No! It's not a joke.

Take a look here: http://msdn.microsoft.com/en-us/library/ms186939.aspx

Character data types that are either fixed-length, nchar, or variable-length, nvarchar, Unicode data and use the UNICODE UCS-2 character set.

And also here: http://en.wikipedia.org/wiki/UTF-16

The older UCS-2 (2-byte Universal Character Set) is a similar character encoding that was superseded by UTF-16 in version 2.0 of the Unicode standard in July 1996.

var_dump() can do this.

This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure.

Why don't you disable the view cache with cache-view="false"?

In your view add this to the ion-nav-view like that:

<ion-nav-view name="other" cache-view="false"></ion-nav-view>

Or in your stateProvider:

$stateProvider.state('other', {
   cache: false,
   url : '/other',
   templateUrl : 'templates/other/other.html'
})

Either one will make your controller being called always.

This is how I got rid of it:

1. Install the MinGW.
2. Select all files in the Basic Setup and select apply the changes.
3. Select new C++ Project You will be able to see "MinGW GCC" in the toolchain section select the same and create project.

Also you can make your domain object Director final. It is not perfect solution but it prevent creating proxy-subclass of you domain class.

Place the following code in the ASPX.

<script language=javascript>
function CloseWindow() 
{
    window.open('', '_self', '');
    window.close();
}
</script>

Place the following code in the code behind button click event.

string myclosescript = "<script language='javascript' type='text/javascript'>CloseWindow();</script>";

Page.ClientScript.RegisterStartupScript(GetType(), "myclosescript", myclosescript);

If you dont have any processing before close then you can directly put the following code in the ASPX itself in the button click tag.

OnClientClick="CloseWindow();"

Hope this helps.

I know this is old, but I recently faced the same issue and I managed to pick the element by accessing only the attribute like this: document.querySelector('[name="your-selector-name-here"]');

Just in case anyone would ever need this :)

Installing pipenv globally can have an adverse effect by overwriting the global/system-managed pip installation, thus resulting in import errors when trying to run pip.

You can install pipenv at the user level:

pip install --user pipenv

This should install pipenv at a user-level in /home/username/.local so that it does not conflict with the global version of pip. In my case, that still did not work after running the '--user' switch, so I ran the longer 'fix what I screwed up' command once to restore the system managed environment:

sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall

^ found here: Error after upgrading pip: cannot import name 'main'

and then did the following:

mkdir /home/username/.local ... if it doesn't already exist

export PYTHONUSERBASE=/home/username/.local

Make sure the export took effect (bit me once during this process):

echo $PYTHONUSERBASE

Then, I ran the pip install --user pipenv and all was well. I could then run pipenv from the CLI and it did not overwrite the global/system-managed pip module. Of course, this is specific to the user so you want to make sure you install pipenv this way while working as the user you wish to use pipenv.

References:

https://pipenv.readthedocs.io/en/latest/diagnose/#no-module-named-module-name https://pipenv.readthedocs.io/en/latest/install/#pragmatic-installation-of-pipenv https://pip.pypa.io/en/stable/user_guide/#user-installs

I don't see what the problem with the timeit module is. This is probably the simplest way to do it.

import timeit
timeit.timeit(a, number=1)

Its also possible to send arguments to the functions. All you need is to wrap your function up using decorators. More explanation here: http://www.pythoncentral.io/time-a-python-function/

The only case where you might be interested in writing your own timing statements is if you want to run a function only once and are also want to obtain its return value.

The advantage of using the timeit module is that it lets you repeat the number of executions. This might be necessary because other processes might interfere with your timing accuracy. So, you should run it multiple times and look at the lowest value.

Below is example to call synchronously but you can easily change to async by using await-sync:

var pairs = new List<KeyValuePair<string, string>>
            {
                new KeyValuePair<string, string>("login", "abc")
            };

var content = new FormUrlEncodedContent(pairs);

var client = new HttpClient {BaseAddress = new Uri("http://localhost:6740")};

    // call sync
var response = client.PostAsync("/api/membership/exist", content).Result; 
if (response.IsSuccessStatusCode)
{
}

bool = bool != true;

One of the cases.

I found the following code the jQuery UI dialog function for open.

c([]).add(d.find(".ui-dialog-content :tabbable:first")).add(d.find(".ui-dialog-buttonpane :tabbable:first")).add(d).filter(":first").focus();

You can either workaround the jQuery behaviour or change the behaviour.

tabindex -1 works as a workaround.

use like this :-

gridview1.DataSource = ds.Tables[0]; <-- Use index or your table name which you want to bind
gridview1.DataBind();

I hope it helps!!

When you only need to check for equality, you can also simply use the in operator to do a membership test in a sequence of accepted elements:

if message.value[0] in ('/', '\\'):
    do_stuff()

Note: For those dealing with CJK text (Chinese, Japanese, and Korean), the double-byte space (Unicode \u3000) is not included in \s for any implementation I've tried so far (Perl, .NET, PCRE, Python). You'll need to either normalize your strings first (such as by replacing all \u3000 with \u0020), or you'll have to use a character set that includes this codepoint in addition to whatever other whitespace you're targeting, such as [ \t\u3000].

If you're using Perl or PCRE, you have the option of using the \h shorthand for horizontal whitespace, which appears to include the single-byte space, double-byte space, and tab, among others. See the Match whitespace but not newlines (Perl) thread for more detail.

However, this \h shorthand has not been implemented for .NET and C#, as best I've been able to tell.

Just add the order with this tag

@JsonPropertyOrder({ "property1", "property2"})

The difference is:
- orphanRemoval = true: "Child" entity is removed when it's no longer referenced (its parent may not be removed).
- CascadeType.REMOVE: "Child" entity is removed only when its "Parent" is removed.

Specify the property in filter, of object on which you want to apply filter:

//Suppose Object
var users = [{
  "firstname": "XYZ",
  "lastname": "ABC",
  "Address": "HOUSE NO-1, Example Street, Example Town"
},
{
  "firstname": "QWE",
  "lastname": "YUIKJH",
  "Address": "HOUSE NO-11, Example Street1, Example Town1"
}]

But you want to apply filter only on firstname

<input type = "text" ng-model = "first_name_model"/>
<div ng-repeat="user in users| filter:{ firstname: first_name_model}">

Are you looking for generic Search(Filter) across the item in the object list without specifying the item key

Input

var productList = [{category: 'Sporting Goods', price: '$49.99', stocked: true, name: 'Football'}, {category: 'Sporting Goods', price: '$9.99', stocked: true, name: 'Baseball'}, {category: 'Sporting Goods', price: '$29.99', stocked: false, name: 'Basketball'}, {category: 'Electronics', price: '$99.99', stocked: true, name: 'iPod Touch'}, {category: 'Electronics', price: '$399.99', stocked: false, name: 'iPhone 5'}, {category: 'Electronics', price: '$199.99', stocked: true, name: 'Nexus 7'}]
function customFilter(objList, text){
if(undefined === text || text === '' ) return objList;
return objList.filter(product => {
    let flag;
    for(let prop in product){
        flag = false;
        flag = product[prop].toString().indexOf(text) > -1;
        if(flag)
        break;
    }
return flag;
});}

Execute

customFilter(productList, '$9');

do
{
  //  whatever
} while ( !condition );

You probably want to look into the observer pattern.

Here's some sample code to get yourself started:

import java.util.*;

// An interface to be implemented by everyone interested in "Hello" events
interface HelloListener {
    void someoneSaidHello();
}

// Someone who says "Hello"
class Initiater {
    private List<HelloListener> listeners = new ArrayList<HelloListener>();

    public void addListener(HelloListener toAdd) {
        listeners.add(toAdd);
    }

    public void sayHello() {
        System.out.println("Hello!!");

        // Notify everybody that may be interested.
        for (HelloListener hl : listeners)
            hl.someoneSaidHello();
    }
}

// Someone interested in "Hello" events
class Responder implements HelloListener {
    @Override
    public void someoneSaidHello() {
        System.out.println("Hello there...");
    }
}

class Test {
    public static void main(String[] args) {
        Initiater initiater = new Initiater();
        Responder responder = new Responder();

        initiater.addListener(responder);

        initiater.sayHello();  // Prints "Hello!!!" and "Hello there..."
    }
}

Since HTML is officially an SGML application, the comment syntax used in HTML documents is actually the SGML comment syntax. Unfortunately this syntax is a bit unclear at first.

The definition of an SGML comment is basically as follows:

A comment declaration starts with <!, followed by zero or more comments, followed by >. A comment starts and ends with "--", and does not contain any occurrence of "--".

This means that the following are all legal SGML comments:

1. <!-- Hello -->
2. <!-- Hello -- -- Hello-->
3. <!---->
4. <!------ Hello -->
5. <!>

Note that an "empty" comment tag, with just "--" characters, should always have a multiple of four "-" characters to be legal. (And yes, <!> is also a legal comment - it's the empty comment).

Not all HTML parsers get this right. For example, "<!------> hello-->" is a legal comment, as you can verify with the rule above. It is a comment tag with two comments; the first is empty and the second one contains "> hello". If you try it in a browser, you will find that the text is displayed on screen.

There are two possible reasons for this:

1. The browser sees the ">" character and thinks the comment ends there.
2. The browser sees the "-->" text and thinks the comment ends there.

There is also the problem with the "--" sequence. Some people have a habit of using things like "<!-------------->" as separators in their source. Unfortunately, in most cases, the number of "-" characters is not a multiple of four. This means that a browser who tries to get it right will actually get it wrong here and actually hide the rest of the document.

For this reason, use the following simple rule to compose valid and accepted comments:

An HTML comment begins with "<!--", ends with "-->" and does not contain "--" or ">" anywhere in the comment.

There are some things to change in your code:

1. Change the name of your output to 'output.mp4' (change to .mp4)
2. I had the the same issues that people have in the comments, so I changed the fourcc to 0x7634706d: out = cv2.VideoWriter('output.mp4',0x7634706d , 20.0, (640,480))

Why not just simplify it to if($_GET['id']). It will return true or false depending on status of the parameter's existence.

You can use overflow:auto;

You can also control the x or y axis individually with the overflow-x and overflow-y properties.

Example:

.content {overflow:auto;}
.content {overflow-y:auto;}
.content {overflow-x:auto;}

 var flag = 0;

 $('#target').click(function() {
    flag = 1;
 });

 if (flag == 1)
 {
  alert("Clicked");
 }
 else
 {
   alert("Not clicked");
 }

If you do android native code development using NDK, give Visual Studio a try. (Not a typo!!!) Check out: http://ian-ni-lewis.blogspot.com/2011/01/its-like-coming-home-again.html

and: http://code.google.com/p/vs-android/

As the name implies, :nth-child() allows you to construct an arithmetic expression using the n variable in addition to constant numbers. You can perform addition (+), subtraction (-) and coefficient multiplication (an where a is an integer, including positive numbers, negative numbers and zero).

Here's how you would rewrite the above selector list:

div:nth-child(4n)

For an explanation on how these arithmetic expressions work, see my answer to this question, as well as the spec.

Note that this answer assumes that all of the child elements within the same parent element are of the same element type, div. If you have any other elements of different types such as h1 or p, you will need to use :nth-of-type() instead of :nth-child() to ensure you only count div elements:

<body>
  <h1></h1>
  <div>1</div>  <div>2</div>
  <div>3</div>  <div>4</div>
  <h2></h2>
  <div>5</div>  <div>6</div>
  <div>7</div>  <div>8</div>
  <h2></h2>
  <div>9</div>  <div>10</div>
  <div>11</div> <div>12</div>
  <h2></h2>
  <div>13</div> <div>14</div>
  <div>15</div> <div>16</div>
</body>

For everything else (classes, attributes, or any combination of these), where you're looking for the nth child that matches an arbitrary selector, you will not be able to do this with a pure CSS selector. See my answer to this question.

By the way, there's not much of a difference between 4n and 4n + 4 with regards to :nth-child(). If you use the n variable, it starts counting at 0. This is what each selector would match:

:nth-child(4n)

4(0) = 0
4(1) = 4
4(2) = 8
4(3) = 12
4(4) = 16
...

:nth-child(4n+4)

4(0) + 4 = 0  + 4 = 4
4(1) + 4 = 4  + 4 = 8
4(2) + 4 = 8  + 4 = 12
4(3) + 4 = 12 + 4 = 16
4(4) + 4 = 16 + 4 = 20
...

As you can see, both selectors will match the same elements as above. In this case, there is no difference.

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

The question is how to call a C function from Python, if I understood correctly. Then the best bet are Ctypes (BTW portable across all variants of Python).

>>> from ctypes import *
>>> libc = cdll.msvcrt
>>> print libc.time(None)
1438069008
>>> printf = libc.printf
>>> printf("Hello, %s\n", "World!")
Hello, World!
14
>>> printf("%d bottles of beer\n", 42)
42 bottles of beer
19

For a detailed guide you may want to refer to my blog article.

You can use the $$ variable.

I know of psExec tools which you can download from here

There comes a psinfo.exe from the tools package. The basic usage is in the following manner in powershell/cmd.

However you could have a lot of options with it

Usage: psinfo [[\computer[,computer[,..] | @file [-u user [-p psswd]]] [-h] [-s] [-d] [-c [-t delimiter]] [filter]

\computer Perform the command on the remote computer or computers specified. If you omit the computer name the command runs on the local system, and if you specify a wildcard (\*), the command runs on all computers in the current domain.

@file   Run the command on each computer listed in the text file specified.
-u  Specifies optional user name for login to remote computer.
-p  Specifies optional password for user name. If you omit this you will be prompted to enter a hidden password.
-h  Show list of installed hotfixes.
-s  Show list of installed applications.
-d  Show disk volume information.
-c  Print in CSV format.
-t  The default delimiter for the -c option is a comma, but can be overriden with the specified character.

filter Psinfo will only show data for the field matching the filter. e.g. "psinfo service" lists only the service pack field.

You can use these options as well, either use \footnotesize or \tiny. This would really help in fitting big tables.

\begin{table}[htbp]
\footnotesize
\caption{Information on making the table size small}
\label{table:table1}
\begin{tabular}{ll}
    \toprule
    S.No       & HMD           \\
    \midrule
    1          & HTC Vive \\
    2          & HTC Vive Pro   \\
    \bottomrule
\end{tabular}
\end{table}

I found an extension method that works quite well

public static string ToHex(this Color color)
{
    return String.Format("#{0}{1}{2}{3}"
        , color.A.ToString("X").Length == 1 ? String.Format("0{0}", color.A.ToString("X")) : color.A.ToString("X")
        , color.R.ToString("X").Length == 1 ? String.Format("0{0}", color.R.ToString("X")) : color.R.ToString("X")
        , color.G.ToString("X").Length == 1 ? String.Format("0{0}", color.G.ToString("X")) : color.G.ToString("X")
        , color.B.ToString("X").Length == 1 ? String.Format("0{0}", color.B.ToString("X")) : color.B.ToString("X"));
}

Since the question is about "how it works", some readers may want to see more nuts and bolts. Specifically, the method in question is the __missing__(key) method. See: https://docs.python.org/2/library/collections.html#defaultdict-objects .

More concretely, this answer shows how to make use of __missing__(key) in a practical way: https://stackoverflow.com/a/17956989/1593924

To clarify what 'callable' means, here's an interactive session (from 2.7.6 but should work in v3 too):

>>> x = int
>>> x
<type 'int'>
>>> y = int(5)
>>> y
5
>>> z = x(5)
>>> z
5

>>> from collections import defaultdict
>>> dd = defaultdict(int)
>>> dd
defaultdict(<type 'int'>, {})
>>> dd = defaultdict(x)
>>> dd
defaultdict(<type 'int'>, {})
>>> dd['a']
0
>>> dd
defaultdict(<type 'int'>, {'a': 0})

That was the most typical use of defaultdict (except for the pointless use of the x variable). You can do the same thing with 0 as the explicit default value, but not with a simple value:

>>> dd2 = defaultdict(0)

Traceback (most recent call last):
  File "<pyshell#7>", line 1, in <module>
    dd2 = defaultdict(0)
TypeError: first argument must be callable

Instead, the following works because it passes in a simple function (it creates on the fly a nameless function which takes no arguments and always returns 0):

>>> dd2 = defaultdict(lambda: 0)
>>> dd2
defaultdict(<function <lambda> at 0x02C4C130>, {})
>>> dd2['a']
0
>>> dd2
defaultdict(<function <lambda> at 0x02C4C130>, {'a': 0})
>>> 

And with a different default value:

>>> dd3 = defaultdict(lambda: 1)
>>> dd3
defaultdict(<function <lambda> at 0x02C4C170>, {})
>>> dd3['a']
1
>>> dd3
defaultdict(<function <lambda> at 0x02C4C170>, {'a': 1})
>>>

finalize method is not guaranteed.This method is called when the object becomes eligible for GC. There are many situations where the objects may not be garbage collected.

In my case the -n 1 option doesn't work. On Windows I've found that the following sequence of commands works fine:

git rev-list -1 --before="2012-01-15 12:00" master

This returns the appropriate commit's SHA for the given date, and then:

git checkout SHA

From here and here: (after i googled your title)

• Alternate key - An alternate key is any candidate key which is not selected to be the primary key
• Candidate key - A candidate key is a field or combination of fields that can act as a primary key field for that table to uniquely identify each record in that table.
• Compound key - compound key (also called a composite key or concatenated key) is a key that consists of 2 or more attributes.
• Primary key - a primary key is a value that can be used to identify a unique row in a table. Attributes are associated with it. Examples of primary keys are Social Security numbers (associated to a specific person) or ISBNs (associated to a specific book). In the relational model of data, a primary key is a candidate key chosen as the main method of uniquely identifying a tuple in a relation.
• Superkey - A superkey is defined in the relational model as a set of attributes of a relation variable (relvar) for which it holds that in all relations assigned to that variable there are no two distinct tuples (rows) that have the same values for the attributes in this set. Equivalently a superkey can also be defined as a set of attributes of a relvar upon which all attributes of the relvar are functionally dependent.
• Foreign key - a foreign key (FK) is a field or group of fields in a database record that points to a key field or group of fields forming a key of another database record in some (usually different) table. Usually a foreign key in one table refers to the primary key (PK) of another table. This way references can be made to link information together and it is an essential part of database normalization

This message will appear if you are using a case-insensitive file system (e.g. on a Mac) and you're trying to capitalize the name (or another change of case). In which case you need to rename to a third, dummy, name:

svn mv file-name_ FILE_Name

Take a look at WinRun4J. It's windows only but that's because unix has executable scripts that look (to the user) like bins. You can also easily modify WinRun4J to compile on unix.

It does require a config file, but again, recompile it with hard-coded options and it works like a config-less exe.

A quick gotcha that I learned the hard way (basically spending 4 hours on Google), you can use PageMethods in your ASPX file to return JSON (with the [ScriptMethod()] marker) for a static method, however if you decide to move your static methods to an asmx file, it cannot be a static method.

Also, you need to tell the web service Content-Type: application/json in order to get JSON back from the call (I'm using jQuery and the 3 Mistakes To Avoid When Using jQuery article was very enlightening - its from the same website mentioned in another answer here).

PowerShell comes with a built in command for it. So running directly from a .bat file:

powershell -ExecutionPolicy ByPass -Command Send-MailMessage ^
    -SmtpServer server.address.name ^
    -To [email protected] ^
    -From [email protected] ^
    -Subject Testing ^
    -Body 123

_{NB -ExecutionPolicy ByPass is only needed if you haven't set up permissions for running PS from CMD}

_{Also for those looking to call it from within powershell, drop everything before -Command [inclusive], and ` will be your escape character (not ^)}

I found the answer, For those who are looking for the same thing here is how I did it. You should not consider uploading images to the database instead you can store the name of the uploaded file in your database and then retrieve the file name and use it where ever you want to display the image.

HTML CODE

<input type="file" name="imageUpload" id="imageUpload">

PHP CODE

if(isset($_POST['submit'])) {

    //Process the image that is uploaded by the user

    $target_dir = "uploads/";
    $target_file = $target_dir . basename($_FILES["imageUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

    if (move_uploaded_file($_FILES["imageUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["imageUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }

    $image=basename( $_FILES["imageUpload"]["name"],".jpg"); // used to store the filename in a variable

    //storind the data in your database
    $query= "INSERT INTO items VALUES ('$id','$title','$description','$price','$value','$contact','$image')";
    mysql_query($query);

    require('heading.php');
    echo "Your add has been submited, you will be redirected to your account page in 3 seconds....";
    header( "Refresh:3; url=account.php", true, 303);
}

CODE TO DISPLAY THE IMAGE

while($row = mysql_fetch_row($result)) {
    echo "<tr>";
    echo "<td><img src='uploads/$row[6].jpg' height='150px' width='300px'></td>";
    echo "</tr>\n";
}

I think the purpose for regex is much different from indexOf. indexOf simply find the occurance of a certain string while in regex you can use wildcards like [A-Z] which means it will find any capital character in the word without stating the actual character.

Example:

 var index = "This is a string".indexOf("is");_x000D_
 console.log(index);_x000D_
 var length = "This is a string".match(/[a-z]/g).length;_x000D_
 // where [a-z] is a regex wildcard expression thats why its slower_x000D_
 console.log(length);

To set headers in an Axios POST request, pass the third object to the axios.post() call.

const token = '..your token..'

axios.post(url, {
  //...data
}, {
  headers: {
    'Authorization': `Basic ${token}` 
  }
})

To set headers in an Axios GET request, pass a second object to the axios.get() call.

const token = '..your token..' 

axios.get(url, {
  headers: {
    'Authorization': `Basic ${token}`
  }
})

Use below command on UNIX terminal :

java -XshowSettings

This will display all java properties and system settings. In this look for java.io.tmpdir value.

Basically local variables aren't automatically initialized. Hence using them without initializing would result in an exception.

Only the following variables are automatically initialized to their default values:

• Static variables
• Instance variables of class and struct instances
• Array elements

The default values are as follows (assigned in default constructor of a class):

• The default value of a variable of reference type is null.
• For integer types, the default value is 0
• For char, the default value is `\u0000'
• For float, the default value is 0.0f
• For double, the default value is 0.0d
• For decimal, the default value is 0.0m
• For bool, the default value is false
• For an enum type, the default value is 0
• For a struct type, the default value is obtained by setting all value type fields to their default values

As far as later parts of your question are conerned:

• The reason why all variables which are not automatically initialized to default values should be initialized is a restriction imposed by compiler.
• private bool foo = false; This is indeed redundant since this is an instance variable of a class. Hence this would be initialized to false in the default constructor. Hence no need to set this to false yourself.

I found it interesting to use list comprehension or map with just one object name x. Note that whenever x is reassigned, its id(x) changes, i.e. points to a different object.

x = [1, 2, 3]
id(x)
2707834975552
x = [1.5 * x for x in x]
id(x)
2707834976576
x
[1.5, 3.0, 4.5]
list(map(lambda x : 2 * x / 3, x))
[1.0, 2.0, 3.0]
id(x) # not reassigned
2707834976576
x = list(map(lambda x : 2 * x / 3, x))
x
[1.0, 2.0, 3.0]
id(x)

Adding array elements dynamically to an Array And adding new element to an Array

$samplearr=array();
$count = 0;
foreach ($rslt as $row) {
        $arr['feeds'][$count]['feed_id'] = $row->feed_id;
        $arr['feeds'][$count]['feed_title'] = $row->feed_title;
        $arr['feeds'][$count]['feed_url'] = $row->feed_url;
        $arr['feeds'][$count]['cat_name'] = $this->get_catlist_details($row->feed_id);
        foreach ($newelt as $cat) {
            array_push($samplearr, $cat);              
        }
        ++$count;
}
$arr['categories'] = array_unique($samplearr); //,SORT_STRING

$response = array("status"=>"success","response"=>"Categories exists","result"=>$arr);

I humbly submit a category to make this less annoying:

@interface NSData (EasyUTF8)

// Safely decode the bytes into a UTF8 string
- (NSString *)asUTF8String;

@end

and

@implementation NSData (EasyUTF8)

- (NSString *)asUTF8String {
    return [[NSString alloc] initWithData:self encoding:NSUTF8StringEncoding];    
}

@end

(Note that if you're not using ARC you'll need an autorelease there.)

Now instead of the appallingly verbose:

NSData *data = ...
[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

You can do:

NSData *data = ...
[data asUTF8String];

My case was a simple oversight.

I put the JUnit dependency declaration inside <dependencies> under the <dependencyManagement/> node instead of <project/> in the POM file. Correct way is:

In practice, I have found that you need to be a bit careful, especially if you are using a bit of xml repeatedly. Suppose, for example, that you have a table that you wish to create a table row for each entry in a list. You've set up some xml:

In my_table_row.xml:

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android" 
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent" android:id="@+id/myTableRow">
    <ImageButton android:src="@android:drawable/ic_menu_delete" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/rowButton"/>
    <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:textAppearance="?android:attr/textAppearanceMedium" android:text="TextView" android:id="@+id/rowText"></TextView>
</TableRow>

Then you want to create it once per row with some code. It assume that you have defined a parent TableLayout myTable to attach the Rows to.

for (int i=0; i<numRows; i++) {
    /*
     * 1. Make the row and attach it to myTable. For some reason this doesn't seem
     * to return the TableRow as you might expect from the xml, so you need to
     * receive the View it returns and then find the TableRow and other items, as
     * per step 2.
     */
    LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v =  inflater.inflate(R.layout.my_table_row, myTable, true);

    // 2. Get all the things that we need to refer to to alter in any way.
    TableRow    tr        = (TableRow)    v.findViewById(R.id.profileTableRow);
    ImageButton rowButton = (ImageButton) v.findViewById(R.id.rowButton);
    TextView    rowText   = (TextView)    v.findViewById(R.id.rowText);

    // 3. Configure them out as you need to
    rowText.setText("Text for this row");
    rowButton.setId(i); // So that when it is clicked we know which one has been clicked!
    rowButton.setOnClickListener(this); // See note below ...           

    /*
     * To ensure that when finding views by id on the next time round this
     * loop (or later) gie lots of spurious, unique, ids.
     */
    rowText.setId(1000+i);
    tr.setId(3000+i);
}

For a clear simple example on handling rowButton.setOnClickListener(this), see Onclicklistener for a programatically created button.

Try:

var firstElement = lstComp.First();

You can also use FirstOrDefault() just in case lstComp does not contain any items.

Edit:

To get the Component Value:

var firstElement = lstComp.First().ComponentValue("Dep");

This would assume there is an element in lstComp. An alternative and safer way would be...

var firstOrDefault = lstComp.FirstOrDefault();
if (firstOrDefault != null) 
{
    var firstComponentValue = firstOrDefault.ComponentValue("Dep");
}

For not balanced searching tree, it takes O(n).

For balanced searching tree, it takes O(k + log n) in the worst case but just O(k) in Amortized sense.

Having and managing the extra integer for every node: the size of the sub-tree gives O(log n) time complexity. Such balanced searching tree is usually called RankTree.

In general, there are solutions (based not on tree).

This will never work, because the JS VM has moved on from that async_call and returned the value, which you haven't set yet.

Don't try to fight what is natural and built-in the language behaviour. You should use a callback technique or a promise.

function f(input, callback) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) { callback(result) };

}

The other option is to use a promise, have a look at Q. This way you return a promise, and then you attach a then listener to it, which is basically the same as a callback. When the promise resolves, the then will trigger.

I thought Activity was deprecated

No.

So for API Level 22 (with a minimum support for API Level 15 or 16), what exactly should I use both to host the components, and for the components themselves? Are there uses for all of these, or should I be using one or two almost exclusively?

Activity is the baseline. Every activity inherits from Activity, directly or indirectly.

FragmentActivity is for use with the backport of fragments found in the support-v4 and support-v13 libraries. The native implementation of fragments was added in API Level 11, which is lower than your proposed minSdkVersion values. The only reason why you would need to consider FragmentActivity specifically is if you want to use nested fragments (a fragment holding another fragment), as that was not supported in native fragments until API Level 17.

AppCompatActivity is from the appcompat-v7 library. Principally, this offers a backport of the action bar. Since the native action bar was added in API Level 11, you do not need AppCompatActivity for that. However, current versions of appcompat-v7 also add a limited backport of the Material Design aesthetic, in terms of the action bar and various widgets. There are pros and cons of using appcompat-v7, well beyond the scope of this specific Stack Overflow answer.

ActionBarActivity is the old name of the base activity from appcompat-v7. For various reasons, they wanted to change the name. Unless some third-party library you are using insists upon an ActionBarActivity, you should prefer AppCompatActivity over ActionBarActivity.

So, given your minSdkVersion in the 15-16 range:

• If you want the backported Material Design look, use AppCompatActivity

• If not, but you want nested fragments, use FragmentActivity

• If not, use Activity

Just adding from comment as note: AppCompatActivity extends FragmentActivity, so anyone who needs to use features of FragmentActivity can use AppCompatActivity.

Instead of using divider in dialog, use the view in the custom layout and set the layout as custom layout in dialog.

custom_popup.xml:

<?xml version="1.0" encoding="utf-8"?>

        android:layout_height="wrap_content"
        android:gravity="center"
        android:paddingBottom="10dp"
        android:paddingTop="10dp"
        android:text="AlertDialog"

        <com.divago.view.TextViewRegular
            android:id="@+id/txtPopup"

            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </ScrollView>
</RelativeLayout>

activity.java:

public void showPopUp(String title, String text) {

    LayoutInflater inflater = getLayoutInflater();
    View alertLayout = inflater.inflate(R.layout.custom_popup, null);

    TextView txtContent = alertLayout.findViewById(R.id.txtPopup);
    txtContent.setText(text);

    TextView txtTitle = alertLayout.findViewById(R.id.txtTitle);
    txtTitle.setText(title);

    AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setView(alertLayout);
    alert.setCancelable(true);

    alert.setPositiveButton("Done", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });

    AlertDialog dialog = alert.create();
    dialog.show();
}

One can use base python for this. The code needs a function to flatten lists of lists:

def flatten(B):    # function needed for code below;
    A = []
    for i in B:
        if type(i) == list: A.extend(i)
        else: A.append(i)
    return A

Then one can run:

L = [[1,2,3],[4,5,6],[7,8,9,10]]

outlist =[]; templist =[[]]
for sublist in L:
    outlist = templist; templist = [[]]
    for sitem in sublist:
        for oitem in outlist:
            newitem = [oitem]
            if newitem == [[]]: newitem = [sitem]
            else: newitem = [newitem[0], sitem]
            templist.append(flatten(newitem))

outlist = list(filter(lambda x: len(x)==len(L), templist))  # remove some partial lists that also creep in;
print(outlist)

Output:

[1, 5, 7], [2, 5, 7], [3, 5, 7],

From plt.imshow() official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 10000, 0, 10], aspect = 1000)

Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.

plt.imshow(data, origin = 'lower',  extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')

To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1] and y_max - y_min = y_res * data.shape[0], where extent = [x_min, x_max, y_min, y_max]. By default, aspect = 1, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower',  extent = [0, 5, 0, 5])

The aspect of color pixel is x_res / y_res. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.

data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.5)

The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.2)

Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.

Try PowerPoint ActiveX 2.4. This is an ActiveX component that embeds PowerPoint into an OCX.

Since you are using just Internet Explorer 6 and Internet Explorer 7 you can embed this component into the HTML.

Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type

C:\folder\app.exe/xC:\folder\file.txt

then my application launches, and creates a file in the specified directory with the specified name.

I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put

$s = New-PSSession -computername NAME -credential LOGIN
    Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s

(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.

*I can also have my application push the file back to my own local computer by changing the script-block to

C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"

You need the quotes if your file-path has a space in it.

EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:

cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"

this solved all of the problems that I have been having recently.

EDIT EDIT: Had more problems, and found a much better way to do it.

start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"

and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)

Thanks for enlightening us Cypawer.

The answers referring to simply calling array() are not quite correct: when the buffer has been partially consumed, or is referring to a part of an array (you can ByteBuffer.wrap an array at a given offset, not necessarily from the beginning), we have to account for that in our calculations. This is the general solution that works for buffers in all cases (does not cover encoding):

if (myByteBuffer.hasArray()) {
    return new String(myByteBuffer.array(),
        myByteBuffer.arrayOffset() + myByteBuffer.position(),
        myByteBuffer.remaining());
} else {
    final byte[] b = new byte[myByteBuffer.remaining()];
    myByteBuffer.duplicate().get(b);
    return new String(b);
}

For the concerns related to encoding, see Andy Thomas' answer.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

Since all responses to this make use of the now long-deprecated abstract WebMvcConfigurer Adapter instead of the WebMvcInterface (as already noted by @sebdooe), here is a working minimal example for a SpringBoot (2.1.4) application with an Interceptor:

Minimal.java:

@SpringBootApplication
public class Minimal
{
    public static void main(String[] args)
    {
        SpringApplication.run(Minimal.class, args);
    }
}

MinimalController.java:

@RestController
@RequestMapping("/")
public class Controller
{
    @GetMapping("/")
    @ResponseBody
    public ResponseEntity<String> getMinimal()
    {
        System.out.println("MINIMAL: GETMINIMAL()");

        return new ResponseEntity<String>("returnstring", HttpStatus.OK);
    }
}

Config.java:

@Configuration
public class Config implements WebMvcConfigurer
{
    //@Autowired
    //MinimalInterceptor minimalInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addInterceptor(new MinimalInterceptor());
    }
}

MinimalInterceptor.java:

public class MinimalInterceptor extends HandlerInterceptorAdapter
{
    @Override
    public boolean preHandle(HttpServletRequest requestServlet, HttpServletResponse responseServlet, Object handler) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR PREHANDLE CALLED");

        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR POSTHANDLE CALLED");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception exception) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR AFTERCOMPLETION CALLED");
    }
}

works as advertised

The output will give you something like:

This gives you the list of column names of a data frame df.

This worked for me

You can concat the data in this way:

InfoDF = pd.DataFrame()
tempDF = pd.DataFrame(rows,columns=['id','min_date'])

InfoDF = pd.concat([InfoDF,tempDF])

You need to split the string:

>>> s = 'http://www.domain.com/?s=some&two=20'
>>> s.split('&')
['http://www.domain.com/?s=some', 'two=20']

That will return a list as you can see so you can do:

>>> s2 = s.split('&')[0]
>>> print s2
http://www.domain.com/?s=some

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

This answer is about .NET 4.5

According to MSDN, the index for array of bytes cannot be greater than 2147483591. For .NET prior to 4.5 it also was a memory limit for an array. In .NET 4.5 this maximum is the same, but for other types it can be up to 2146435071.

This is the code for illustration:

    static void Main(string[] args)
    {
        // -----------------------------------------------
        // Pre .NET 4.5 or gcAllowVeryLargeObjects unset
        const int twoGig = 2147483591; // magic number from .NET

        var type = typeof(int);          // type to use
        var size = Marshal.SizeOf(type); // type size
        var num = twoGig / size;         // max element count

        var arr20 = Array.CreateInstance(type, num);
        var arr21 = new byte[num];

        // -----------------------------------------------
        // .NET 4.5 with x64 and gcAllowVeryLargeObjects set
        var arr451 = new byte[2147483591];
        var arr452 = Array.CreateInstance(typeof(int), 2146435071);
        var arr453 = new byte[2146435071]; // another magic number

        return;
    }

I wondered why this appeared during my unit tests.

I have added a method declaration to a protocol which included throws; but the potentially throwing method wasn't even used in that particular test. Enabling Zombies in test sounded like too much trouble.

Turns out a ?K clean did the trick. I'm always flabberghasted when that solves actual problems.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7

Use window.onresize:

function updateWindow(){
    x = w.innerWidth || e.clientWidth || g.clientWidth;
    y = w.innerHeight|| e.clientHeight|| g.clientHeight;

    svg.attr("width", x).attr("height", y);
}
d3.select(window).on('resize.updatesvg', updateWindow);

Ruby 1.9+:

ALPHABET = ('a'..'z').to_a
#=> ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

10.times.map { ALPHABET.sample }.join
#=> "stkbssowre"

AndroidRate is a library to help you promote your android app by prompting users to rate the app after using it for a few days.

Module Gradle:

dependencies {
  implementation 'com.vorlonsoft:androidrate:1.0.8'
}

MainActivity.java:

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  AppRate.with(this)
      .setStoreType(StoreType.GOOGLEPLAY) //default is GOOGLEPLAY (Google Play), other options are
                                          //           AMAZON (Amazon Appstore) and
                                          //           SAMSUNG (Samsung Galaxy Apps)
      .setInstallDays((byte) 0) // default 10, 0 means install day
      .setLaunchTimes((byte) 3) // default 10
      .setRemindInterval((byte) 2) // default 1
      .setRemindLaunchTimes((byte) 2) // default 1 (each launch)
      .setShowLaterButton(true) // default true
      .setDebug(false) // default false
      //Java 8+: .setOnClickButtonListener(which -> Log.d(MainActivity.class.getName(), Byte.toString(which)))
      .setOnClickButtonListener(new OnClickButtonListener() { // callback listener.
          @Override
          public void onClickButton(byte which) {
              Log.d(MainActivity.class.getName(), Byte.toString(which));
          }
      })
      .monitor();

  if (AppRate.with(this).getStoreType() == StoreType.GOOGLEPLAY) {
      //Check that Google Play is available
      if (GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this) != ConnectionResult.SERVICE_MISSING) {
          // Show a dialog if meets conditions
          AppRate.showRateDialogIfMeetsConditions(this);
      }
  } else {
      // Show a dialog if meets conditions
      AppRate.showRateDialogIfMeetsConditions(this);
  }
}

The default conditions to show rate dialog is as below:

1. App is launched more than 10 days later than installation. Change via AppRate#setInstallDays(byte).
2. App is launched more than 10 times. Change via AppRate#setLaunchTimes(byte).
3. App is launched more than 1 days after neutral button clicked. Change via AppRate#setRemindInterval(byte).
4. App is launched X times and X % 1 = 0. Change via AppRate#setRemindLaunchTimes(byte).
5. App shows neutral dialog (Remind me later) by default. Change via setShowLaterButton(boolean).
6. To specify the callback when the button is pressed. The same value as the second argument of DialogInterface.OnClickListener#onClick will be passed in the argument of onClickButton.
7. Setting AppRate#setDebug(boolean) will ensure that the rating request is shown each time the app is launched. This feature is only for development!.

Optional custom event requirements for showing dialog

You can add additional optional requirements for showing dialog. Each requirement can be added/referenced as a unique string. You can set a minimum count for each such event (for e.g. "action_performed" 3 times, "button_clicked" 5 times, etc.)

AppRate.with(this).setMinimumEventCount(String, short);
AppRate.with(this).incrementEventCount(String);
AppRate.with(this).setEventCountValue(String, short);

Clear show dialog flag

When you want to show the dialog again, call AppRate#clearAgreeShowDialog().

AppRate.with(this).clearAgreeShowDialog();

When the button presses on

call AppRate#showRateDialog(Activity).

AppRate.with(this).showRateDialog(this);

Set custom view

call AppRate#setView(View).

LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.custom_dialog, (ViewGroup)findViewById(R.id.layout_root));
AppRate.with(this).setView(view).monitor();

Specific theme

You can use a specific theme to inflate the dialog.

AppRate.with(this).setThemeResId(int);

Custom dialog

If you want to use your own dialog labels, override string xml resources on your application.

<resources>
    <string name="rate_dialog_title">Rate this app</string>
    <string name="rate_dialog_message">If you enjoy playing this app, would you mind taking a moment to rate it? It won\'t take more than a minute. Thanks for your support!</string>
    <string name="rate_dialog_ok">Rate It Now</string>
    <string name="rate_dialog_cancel">Remind Me Later</string>
    <string name="rate_dialog_no">No, Thanks</string>
</resources>

Check that Google Play is available

if (GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this) != ConnectionResult.SERVICE_MISSING) {

}

Most common way:

console.log(object);

However I must mention JSON.stringify which is useful to dump variables in non-browser scripts:

console.log( JSON.stringify(object) );

The JSON.stringify function also supports built-in prettification as pointed out by Simon Zyx.

Example:

var obj = {x: 1, y: 2, z: 3};

console.log( JSON.stringify(obj, null, 2) ); // spacing level = 2

The above snippet will print:

{
  "x": 1,
  "y": 2,
  "z": 3
}

On caniuse.com you can view the browsers that support natively the JSON.stringify function: http://caniuse.com/json

You can also use the Douglas Crockford library to add JSON.stringify support on old browsers: https://github.com/douglascrockford/JSON-js

Docs for JSON.stringify: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

I hope this helps :-)

(Explanation in more details can be found in an archived Microsoft KB article.)

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

If you are using Java 9+, you can use ifPresentOrElse() method:

opt.ifPresentOrElse(
   value -> System.out.println("Found: " + value),
   () -> System.out.println("Not found")
);

Just multiply the number by -1 and check if the result is positive.

1. Constant extrapolation

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

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

2. Linear (or other custom) extrapolation

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

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

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

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

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

    return ufunclike

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

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

print f_x([9,10])

Output:

[ 0.04978707  0.03009069]

I wrote a module that can do this, called BFJ. Specifically, the method bfj.match can be used to break up a large stream into discrete chunks of JSON:

const bfj = require('bfj');
const fs = require('fs');

const stream = fs.createReadStream(filePath);

bfj.match(stream, (key, value, depth) => depth === 0, { ndjson: true })
  .on('data', object => {
    // do whatever you need to do with object
  })
  .on('dataError', error => {
    // a syntax error was found in the JSON
  })
  .on('error', error => {
    // some kind of operational error occurred
  })
  .on('end', error => {
    // finished processing the stream
  });

Here, bfj.match returns a readable, object-mode stream that will receive the parsed data items, and is passed 3 arguments:

1. A readable stream containing the input JSON.

2. A predicate that indicates which items from the parsed JSON will be pushed to the result stream.

3. An options object indicating that the input is newline-delimited JSON (this is to process format B from the question, it's not required for format A).

Upon being called, bfj.match will parse JSON from the input stream depth-first, calling the predicate with each value to determine whether or not to push that item to the result stream. The predicate is passed three arguments:

1. The property key or array index (this will be undefined for top-level items).

2. The value itself.

3. The depth of the item in the JSON structure (zero for top-level items).

Of course a more complex predicate can also be used as necessary according to requirements. You can also pass a string or a regular expression instead of a predicate function, if you want to perform simple matches against property keys.

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

find . -type f -name "*.xls" -printf "xls2csv %p %p.csv\n" | bash

bash 4 (recursive)

shopt -s globstar
for xls in /path/**/*.xls
do
  xls2csv "$xls" "${xls%.xls}.csv"
done

Just add below annotation with qualifier name of service in service Implementation class:

@Service("employeeService")
@Transactional
public class EmployeeServiceImpl implements EmployeeService{
}

Later versions of Safari allow you to Disable Cross-Origin Restrictions. Just enable the developer menu from Preferences >> Advanced, and select "Disable Cross-Origin Restrictions" from the develop menu.

If you want local only, then you only need to enable the developer menu, and select "Disable local file restrictions" from the develop menu.

If you really need to send the full path of the uploded file, then you'd probably have to use something like a signed java applet as there isn't any way to get this information if the browser doesn't send it.

Checking Out Code

First go to an empty dir, use "git init" to make it a repository, then clone the remote repo into your own.

git clone [email protected]:/dir/to/repo

Wherever you initially clone from is where "git pull" will pull from by default.

Miguel Sanchez's response is the way it should be. The other way executing Rscript could be 'env' command to run the system wide RScript.

#!/usr/bin/env Rscript

The JDK uses the same code so it seems like there is no "easier" way without clunky third party libraries (which probably don't do anything different anyway). The following is directly copied from java.nio.file.Files.java:

// buffer size used for reading and writing
private static final int BUFFER_SIZE = 8192;

/**
  * Reads all bytes from an input stream and writes them to an output stream.
  */
private static long copy(InputStream source, OutputStream sink) throws IOException {
    long nread = 0L;
    byte[] buf = new byte[BUFFER_SIZE];
    int n;
    while ((n = source.read(buf)) > 0) {
        sink.write(buf, 0, n);
        nread += n;
    }
    return nread;
}

If all you want is a two dimensional container to hold some elements, you could conveniently use a dictionary instead:

Matrix = {}

Then you can do:

Matrix[1,2] = 15
print Matrix[1,2]

This works because 1,2 is a tuple, and you're using it as a key to index the dictionary. The result is similar to a dumb sparse matrix.

As indicated by osa and Josap Valls, you can also use Matrix = collections.defaultdict(lambda:0) so that the missing elements have a default value of 0.

Vatsal further points that this method is probably not very efficient for large matrices and should only be used in non performance-critical parts of the code.

It depends on how you want to use the data in the excel file. If you want to import it into mysql, you could simply save it as a CSV formatted file and then use fgetcsv to parse it.

You can use the DATE() function to extract the date portion of the timestamp:

SELECT * FROM table
WHERE DATE(timestamp) = '2012-05-25'

Though, if you have an index on the timestamp column, this would be faster because it could utilize an index on the timestamp column if you have one:

SELECT * FROM table
WHERE timestamp BETWEEN '2012-05-25 00:00:00' AND '2012-05-25 23:59:59'

a=[];
a.push(['b','c','d','e','f']);

http://www.cplusplus.com/reference/clibrary/cstdio/printf/

the same rules should apply to Java.

in your case it means output of integer values in 2 or more digits, the first being zero if number less than or equal to 9

A simple way is set android:usesCleartextTraffic="true" on you AndroidManifest.xml

android:usesCleartextTraffic="true"

Your AndroidManifest.xml look like

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.dww.drmanar">
   <application
       android:icon="@mipmap/ic_launcher"
       android:label="@string/app_name"
       android:usesCleartextTraffic="true"
       android:theme="@style/AppTheme"
       tools:targetApi="m">
       <activity
            android:name=".activity.SplashActivity"
            android:theme="@style/FullscreenTheme">

The answers here are worth a try, but you should also review your code. Specifically have a read of Polyfun's answer here: How to get rid of deadlock in a SQL Server 2005 and C# application?

It explains the concurrency issue, and how the usage of "with (updlock)" in your queries might correct your deadlock situation - depending really on exactly what your code is doing. If your code does follow this pattern, this is likely a better fix to make, before resorting to dirty reads, etc.
