SET foreign_key_checks = 0;
DROP TABLE IF EXISTS a,b,c;
SET foreign_key_checks = 1;

Then you do not have to worry about dropping them in the correct order, nor whether they actually exist.

N.B. this is for MySQL only (as in the question). Other databases likely have different methods for doing this.

You forgot the table in your syntax:

drop table [table_name]

which drops a table.

Using

drop table if exists [table_name]

checks if the table exists before dropping it.
If it exists, it gets dropped.
If not, no error will be thrown and no action be taken.

Use show create table tbl_name to view the foreign keys

You can use this syntax to drop a foreign key:

ALTER TABLE tbl_name DROP FOREIGN KEY fk_symbol

There's also more information here (see Frank Vanderhallen post): http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html

Slightly more generic version of what @mark_s posted, this helped me

SELECT 
'ALTER TABLE ' +  OBJECT_SCHEMA_NAME(k.parent_object_id) +
'.[' + OBJECT_NAME(k.parent_object_id) + 
'] DROP CONSTRAINT ' + k.name
FROM sys.foreign_keys k
WHERE referenced_object_id = object_id('your table')

just plug your table name, and execute the result of it.

I was able to solve "ORA-00604: error" by Droping with purge.

DROP TABLE tablename PURGE

Most of the given examples assume that for the test range [$a..$b], $a <= $b, i.e. the range extremes are in lower - higher order and most assume that all are integer numbers.
But I needed a function to test if $n was between $a and $b, as described here:

Check if $n is between $a and $b even if:
    $a < $b  
    $a > $b
    $a = $b

All numbers can be real, not only integer.

There is an easy way to test.
I base the test it in the fact that ($n-$a) and ($n-$b) have different signs when $n is between $a and $b, and the same sign when $n is outside the $a..$b range.
This function is valid for testing increasing, decreasing, positive and negative numbers, not limited to test only integer numbers.

function between($n, $a, $b)
{
    return (($a==$n)&&($b==$n))? true : ($n-$a)*($n-$b)<0;
}

Add this 2 lines in your code -

mWebView.setWebChromeClient(new WebChromeClient()); 
mWebView.setWebViewClient(new WebViewClient());?

The best approach when you also have an animated image is this one:

1- You have to create a "WaitForm" that receives the method that it will executed in background. Like this one

public partial class WaitForm : Form
{
    private readonly MethodInvoker method;

    public WaitForm(MethodInvoker action)
    {
        InitializeComponent();
        method = action;
    }

    private void WaitForm_Load(object sender, EventArgs e)
    {
        new Thread(() =>
        {
            method.Invoke();
            InvokeAction(this, Dispose);
        }).Start();
    }

    public static void InvokeAction(Control control, MethodInvoker action)
    {
        if (control.InvokeRequired)
        {
            control.BeginInvoke(action);
        }
        else
        {
            action();
        }
    }
}

2 - You can use the Waitform like this

private void btnShowWait_Click(object sender, EventArgs e)
{
    new WaitForm(() => /*Simulate long task*/ Thread.Sleep(2000)).ShowDialog();
}

Oauth is definitely gaining momentum and becoming popular among enterprise APIs as well. In the app and data driven world, Enterprises are exposing APIs more and more to the outer world in line with Google, Facebook, twitter. With this development a 3 way triangle of authentication gets formed

1) API provider- Any enterprise which exposes their assets by API, say Amazon,Target etc 2) Developer - The one who build mobile/other apps over this APIs 3) The end user- The end user of the service provided by the - say registered/guest users of Amazon

Now this develops a situation related to security - (I am listing few of these complexities) 1) You as an end user wants to allow the developer to access APIs on behalf of you. 2) The API provider has to authenticate the developer and the end user 3) The end user should be able to grant and revoke the permissions for the consent they have given 4) The developer can have varying level of trust with the API provider, in which the level of permissions given to her is different

The Oauth is an authorization framework which tries to solve the above mentioned problem in a standard way. With the prominence of APIs and Apps this problem will become more and more relevant and any standard which tries to solve it - be it ouath or any other - will be something to care about as an API provider/developer and even end user!

break x if ((int)strcmp(y, "hello")) == 0

On some implementations gdb might not know the return type of strcmp. That means you would have to cast, otherwise it would always evaluate to true!

To check the existence of a local variable:

if 'myVar' in locals():
  # myVar exists.

To check the existence of a global variable:

if 'myVar' in globals():
  # myVar exists.

To check if an object has an attribute:

if hasattr(obj, 'attr_name'):
  # obj.attr_name exists.

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

In some cases it is tied to how the field is used. In some DB engines the field differences determine how (and if) you search for text in the field. CharFields are typically used for things that are searchable, like if you want to search for "one" in the string "one plus two". Since the strings are shorter they are less time consuming for the engine to search through. TextFields are typically not meant to be searched through (like maybe the body of a blog) but are meant to hold large chunks of text. Now most of this depends on the DB Engine and like in Postgres it does not matter.

Even if it does not matter, if you use ModelForms you get a different type of editing field in the form. The ModelForm will generate an HTML form the size of one line of text for a CharField and multiline for a TextField.

In addition to @jalchr's solution that helped me, I found that when calling ATL::Base64Encode from a c++ application to encode the content you pass to an ASP.NET webservice, you need something else, too. In addition to

sEncryptedString = sEncryptedString.Replace(' ', '+'); 

from @jalchr's solution, you also need to ensure that you do not use the ATL_BASE64_FLAG_NOPAD flag on ATL::Base64Encode:

 BOOL bEncoded = Base64Encode(lpBuffer,
                    nBufferSizeInBytes,
                    strBase64Encoded.GetBufferSetLength(base64Length),
                    &base64Length,ATL_BASE64_FLAG_NOCRLF/*|ATL_BASE64_FLAG_NOPAD*/);

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

You could install Charles - an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet - on your PC or MAC.

Config steps:

• Let your phone and PC or MAC in a same LAN
• Launch Charles which you installed (default proxy port is 8888)
• Setup your phone's wifi configuration: set the ip of delegate to your PC or MAC's ip, port of delegate to 8888
• Lauch your app in your phone. And monitor http requests on Charles.

You need only one line before the declaration of the class Animal for correct polymorphic serialization/deserialization:

@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class")
public abstract class Animal {
   ...
}

This line means: add a meta-property on serialization or read a meta-property on deserialization (include = JsonTypeInfo.As.PROPERTY) called "@class" (property = "@class") that holds the fully-qualified Java class name (use = JsonTypeInfo.Id.CLASS).

So, if you create a JSON directly (without serialization) remember to add the meta-property "@class" with the desired class name for correct deserialization.

You have a chance to face the java.lang.OutOfMemoryError: Unable to create new native thread whenever the JVM asks for a new thread from the OS. Whenever the underlying OS cannot allocate a new native thread, this OutOfMemoryError will be thrown. The exact limit for native threads is very platform-dependent thus its recommend to find out those limits by running a test similar to the below link example. But, in general, the situation causing java.lang.OutOfMemoryError: Unable to create new native thread goes through the following phases:

1. A new Java thread is requested by an application running inside the JVM
2. JVM native code proxies the request to create a new native thread to the OS The OS tries to create a new native thread which requires memory to be allocated to the thread
3. The OS will refuse native memory allocation either because the 32-bit Java process size has depleted its memory address space – e.g. (2-4) GB process size limit has been hit – or the virtual memory of the OS has been fully depleted
4. The java.lang.OutOfMemoryError: Unable to create new native thread error is thrown.

I sometimes print debugging output to the browser window. Using jQuery, you could send output messages to a display area on your page:

<div id='display'></div>

$('#display').text('array length: ' + myArray.length);

Or if you want to watch JavaScript variables without adding a display area to your page:

function debug(txt) {
    $('body').append("<div style='width:300px;background:orange;padding:3px;font-size:13px'>" + txt + "</div>");
}

You can use actual html tags <xmp> and </xmp> to output the string as is to show all of the tags in between the xmp tags.

Or you can also use on the server Server.UrlEncode or HttpUtility.HtmlEncode.

A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)

If you intend to read the data only from the client-side, you can use the local storage. It's deleted only when the browser's cache is cleared.

Abie, it all comes down to your use case. Rather than relying on someone else's account of their use case, feel free to post your use case to the rabbitmq-discuss list. Asking on twitter will get you some responses too. Best wishes, alexis

Option(getObject) foreach (QueueManager add)

If your find doesn't have a -printf option you can also use basename:

find ./dir1 -type f -exec basename {} \;

something.data() will return a pointer to the data space of the vector.

Without using any custom classes or libraries:

<ImageView
    android:id="@id/img"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:scaleType="fitCenter" />

scaleType="fitCenter" (default when omitted)

• will make it as wide as the parent allows and up/down-scale as needed keeping aspect ratio.

scaleType="centerInside"

• if the intrinsic width of src is smaller than parent width
  will center the image horizontally
• if the intrinsic width of src is larger than parent width
  will make it as wide as the parent allows and down-scale keeping aspect ratio.

It doesn't matter if you use android:src or ImageView.setImage* methods and the key is probably the adjustViewBounds.

df.dropna(subset=['columnName1', 'columnName2'])

When you define a function, you also define what info (arguments) that function needs to work. If it is designed to work without any additional info, and you pass it some, you are going to get that error.

Example: Takes no arguments:

def dog
end

Takes arguments:

def cat(name)
end

When you call these, you need to call them with the arguments you defined.

dog                  #works fine
cat("Fluffy")        #works fine


dog("Fido")          #Returns ArgumentError (1 for 0)
cat                  #Returns ArgumentError (0 for 1)

The linux kernel graphical operations are in /include/linux/fb.h as struct fb_ops. Eventually this is what add-ons like X11, Wayland, or DRM appear to reference. As these operations are only for video cards, not vector or raster hardcopy or tty oriented terminal devices, their usefulness as a GUI is limited; it's just not entirely true you need those add-ons to get graphical output if you don't mind using some assembler to bypass syscall as necessary.

Do you really mean u'String'?

In any event, can't you just do str(string) to get a string rather than a unicode-string? (This should be different for Python 3, for which all strings are unicode.)

In all previous solutions, you must know the name of the attribute or field. A more generic solution for any attribute is this:

let data = 
[{
    "name": "placeHolder",
    "section": "right"
}, {
    "name": "Overview",
    "section": "left"
}, {
    "name": "ByFunction",
    "section": "left"
}, {
    "name": "Time",
    "section": "left"
}, {
    "name": "allFit",
    "section": "left"
}, {
    "name": "allbMatches",
    "section": "left"
}, {
    "name": "allOffers",
    "section": "left"
}, {
    "name": "allInterests",
    "section": "left"
}, {
    "name": "allResponses",
    "section": "left"
}, {
    "name": "divChanged",
    "section": "right"
}]    

function findByKey(key, value) {
    return (item, i) => item[key] === value
}

let findParams = findByKey('name', 'allOffers')
let index = data.findIndex(findParams)

For scripts, I always use ksh because it smooths over gotchas.

But I find bash more comfortable for interactive use. For me the emacs key bindings and tab completion are the main benefits. But that's mostly force of habit, not any technical issue with ksh.

I have been through a lot of trouble so I came up with my own solution, I created this script, just set the path inside script and db name and run it, it will do the trick

#!/bin/bash

FILES= #absolute or relative path to dump directory
DB=`db` #db name
for file in $FILES
do

    name=$(basename $file)
    collection="${name%.*}"
    echo `mongoimport --db "$DB" --file "$name" --collection "$collection"`

done

Maybe someone else has this problem at one point. If you use the UglifyJsPlugin in webpack 2 you need to explicitly specify the sourceMap flag. For example:

new webpack.optimize.UglifyJsPlugin({ sourceMap: true })

I'll give a slightly advanced answer. In Python, functions are first-class objects. This means they can be "dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have."

Calling a function/class instance in Python means invoking the __call__ method of that object. For old-style classes, class instances are also callable but only if the object which creates them has a __call__ method. The same applies for new-style classes, except there is no notion of "instance" with new-style classes. Rather they are "types" and "objects".

As quoted from the Python 2 Data Model page, for function objects, class instances(old style classes), and class objects(new-style classes), "x(arg1, arg2, ...) is a shorthand for x.__call__(arg1, arg2, ...)".

Thus whenever you define a function with the shorthand def funcname(parameters): you are really just creating an object with a method __call__ and the shorthand for __call__ is to just name the instance and follow it with parentheses containing the arguments to the call. Because functions are first class objects in Python, they can be created on the fly with dynamic parameters (and thus accept dynamic arguments). This comes into handy with decorator functions/classes which you will read about later.

For now I suggest reading the Official Python Tutorial.

Given:

A_1 = [10 200 7 150]';
A_2 = [0.001 0.450 0.007 0.200]';

(As others have already pointed out) There are tools to simply compute correlation, most obviously corr:

corr(A_1, A_2);  %Returns 0.956766573975184  (Requires stats toolbox)

You can also use base Matlab's corrcoef function, like this:

M = corrcoef([A_1 A_2]):  %Returns [1 0.956766573975185; 0.956766573975185 1];
M(2,1);  %Returns 0.956766573975184 

Which is closely related to the cov function:

cov([condition(A_1) condition(A_2)]);

As you almost get to in your original question, you can scale and adjust the vectors yourself if you want, which gives a slightly better understanding of what is going on. First create a condition function which subtracts the mean, and divides by the standard deviation:

condition = @(x) (x-mean(x))./std(x);  %Function to subtract mean AND normalize standard deviation

Then the correlation appears to be (A_1 * A_2)/(A_1^2), like this:

(condition(A_1)' * condition(A_2)) / sum(condition(A_1).^2);  %Returns 0.956766573975185

By symmetry, this should also work

(condition(A_1)' * condition(A_2)) / sum(condition(A_2).^2); %Returns 0.956766573975185

And it does.

I believe, but don't have the energy to confirm right now, that the same math can be used to compute correlation and cross correlation terms when dealing with multi-dimensiotnal inputs, so long as care is taken when handling the dimensions and orientations of the input arrays.

To be precise a+=b not actually equals to a = a + b. It actually is a = a + (b). How so? Let me show you a demo,

a = 1;
console.log('a += 1<<2: ', a += 1<<2); // results in 5

a = 1;
// If a += b is equal to a = a + b then this would be 5. But as you see this is not. The result is 8.
console.log('a + 1 << 2: ', a + 1 << 2); // results in 8


a = 1;
// As you can see this results in 5.
console.log('a + (1<<2): ', a + (1<<2)); // results in 5

Because this += or *= or -= or /= etc operators implicitly groups the right hand side.

You can use property dangerouslySetInnerHTML, like this

const Component = React.createClass({_x000D_
  iframe: function () {_x000D_
    return {_x000D_
      __html: this.props.iframe_x000D_
    }_x000D_
  },_x000D_
_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <div dangerouslySetInnerHTML={ this.iframe() } />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_
  <Component iframe={iframe} />,_x000D_
  document.getElementById('container')_x000D_
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="container"></div>

also, you can copy all attributes from the string(based on the question, you get iframe as a string from a server) which contains <iframe> tag and pass it to new <iframe> tag, like that

/**_x000D_
 * getAttrs_x000D_
 * returns all attributes from TAG string_x000D_
 * @return Object_x000D_
 */_x000D_
const getAttrs = (iframeTag) => {_x000D_

_x000D_
  const iframe = doc.getElementsByTagName('iframe')[0];_x000D_
  return [].slice_x000D_
    .call(iframe.attributes)_x000D_
    .reduce((attrs, element) => {_x000D_
      attrs[element.name] = element.value;_x000D_
      return attrs;_x000D_
    }, {});_x000D_
}_x000D_
_x000D_

In case anyone still hunting the cause of this hateful issue, there comes a solution to nail the causing file. https://www.drupal.org/node/1622904#comment-10768958 from Drupal community.

And I quote:

Edit

includes/bootstrap.inc:

function drupal_load(). It is a short function. Find following line: include_once DRUPAL_ROOT . '/' . $filename; Temporarily replace it by

ob_start();
include_once DRUPAL_ROOT . '/' . $filename;
$value = ob_get_contents();
ob_end_clean();
if ($value !== '') {
  $filename = check_plain($filename);
  $value = check_plain($value);
  print "File '$filename' produced unforgivable content: '$value'.";
  exit;
}

Try this :

$('#form1').submit();

or

document.form1.submit();

One should NEVER treat "BLANK" and NULL as the same.

Back in the olden days before there was a SQL standard, Oracle made the design decision that empty strings in VARCHAR/ VARCHAR2 columns were NULL and that there was only one sense of NULL (there are relational theorists that would differentiate between data that has never been prompted for, data where the answer exists but is not known by the user, data where there is no answer, etc. all of which constitute some sense of NULL). By the time that the SQL standard came around and agreed that NULL and the empty string were distinct entities, there were already Oracle users that had code that assumed the two were equivalent. So Oracle was basically left with the options of breaking existing code, violating the SQL standard, or introducing some sort of initialization parameter that would change the functionality of potentially large number of queries. Violating the SQL standard (IMHO) was the least disruptive of these three options.

Oracle has left open the possibility that the VARCHAR data type would change in a future release to adhere to the SQL standard (which is why everyone uses VARCHAR2 in Oracle since that data type's behavior is guaranteed to remain the same going forward).

I noticed that Map should require special treatment, thus with all suggestions in this thread, code will be:

function deepClone( obj ) {
    if( !obj || true == obj ) //this also handles boolean as true and false
        return obj;
    var objType = typeof( obj );
    if( "number" == objType || "string" == objType ) // add your immutables here
        return obj;
    var result = Array.isArray( obj ) ? [] : !obj.constructor ? {} : new obj.constructor();
    if( obj instanceof Map )
        for( var key of obj.keys() )
            result.set( key, deepClone( obj.get( key ) ) );
    for( var key in obj )
        if( obj.hasOwnProperty( key ) )
            result[key] = deepClone( obj[ key ] );
    return result;
}

You can do that in the client side only, in browser that accept Data URIs:

data:application/csv;charset=utf-8,content_encoded_as_url

In your example the Data URI must be:

data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333

You can call this URI by:

• using window.open
• or setting the window.location
• or by the href of an anchor
• by adding the download attribute it will work in chrome, still have to test in IE.

To test, simply copy the URIs above and paste in your browser address bar. Or test the anchor below in a HTML page:

<a download="somedata.csv" href="data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333">Example</a>

To create the content, getting the values from the table, you can use table2CSV and do:

var data = $table.table2CSV({delivery:'value'});

$('<a></a>')
    .attr('id','downloadFile')
    .attr('href','data:text/csv;charset=utf8,' + encodeURIComponent(data))
    .attr('download','filename.csv')
    .appendTo('body');

$('#downloadFile').ready(function() {
    $('#downloadFile').get(0).click();

Most, if not all, versions of IE don't support navigation to a data link, so a hack must be implemented, often with an iframe. Using an iFrame combined with document.execCommand('SaveAs'..), you can get similar behavior on most currently used versions of IE.

To avoid using curl or Chrome plugins you can just use the the built in windows Powershell. From the Powershell command window run

Invoke-WebRequest -UseBasicParsing "http://127.0.0.1:9200/sampleindex/sampleType/" -
Method POST -ContentType "application/json" -Body '{
"user" : "Test",
"post_date" : "2017/11/13 11:07:00",
"message" : "trying out Elasticsearch"
}'

Note the Index name MUST be in lowercase.

Optional parameters are kind of like a macro substitution from what I understand. They are not really optional from the method's point of view. An artifact of that is the behavior you see where you get different results if you cast to an interface.

It is unnecessary. You can use an ORDER BY and just change the sort to DESC to get the same effect.

Because string is defined in the namespace std. Replace string with std::string, or add

using std::string;

below your include lines.

It probably works in main.cpp because some other header has this using line in it (or something similar).

These are 2 methods that can be used to take a value from the selected row

    /// <summary>
    /// Take a value from a the selected row of a DataGrid
    /// ATTENTION : The column's index is absolute : if the DataGrid is reorganized by the user,
    /// the index must change
    /// </summary>
    /// <param name="dGrid">The DataGrid where we take the value</param>
    /// <param name="columnIndex">The value's line index</param>
    /// <returns>The value contained in the selected line or an empty string if nothing is selected</returns>
    public static string getDataGridValueAt(DataGrid dGrid, int columnIndex)
    {
        if (dGrid.SelectedItem == null)
            return "";
        string str = dGrid.SelectedItem.ToString(); // Take the selected line
        str = str.Replace("}", "").Trim().Replace("{", "").Trim(); // Delete useless characters
        if (columnIndex < 0 || columnIndex >= str.Split(',').Length) // case where the index can't be used 
            return "";
        str = str.Split(',')[columnIndex].Trim();
        str = str.Split('=')[1].Trim();
        return str;
    }

    /// <summary>

    /// </summary>
    /// <param name="dGrid">The DataGrid where we take the value.</param>
    /// <param name="columnName">The column's name of the searched value. Be careful, the parameter must be the same as the shown on the dataGrid</param>
    /// <returns>The value contained in the selected line or an empty string if nothing is selected or if the column doesn't exist</returns>
    public static string getDataGridValueAt(DataGrid dGrid, string columnName)
    {
        if (dGrid.SelectedItem == null)
            return "";
        for (int i = 0; i < columnName.Length; i++)
            if (columnName.ElementAt(i) == '_')
            {
                columnName = columnName.Insert(i, "_");
                i++;
            }
        string str = dGrid.SelectedItem.ToString(); // Get the selected Line
        str = str.Replace("}", "").Trim().Replace("{", "").Trim(); // Remove useless characters
        for (int i = 0; i < str.Split(',').Length; i++)
            if (str.Split(',')[i].Trim().Split('=')[0].Trim() == columnName) // Check if the searched column exists in the dataGrid.
                return str.Split(',')[i].Trim().Split('=')[1].Trim();
        return str;
    }

This regex extracts an element from a comma separated list, regardless of contents:

(.+?)(?:,|$)

If you just replace the comma with something else, it should work for any delimiter.

To make it work you should change the following variables in your php.ini:

; display_errors
; Default Value: On
; Development Value: On
; Production Value: Off

; display_startup_errors
; Default Value: On
; Development Value: On
; Production Value: Off

; error_reporting
; Default Value: E_ALL & ~E_NOTICE
; Development Value: E_ALL | E_STRICT 
; Production Value: E_ALL & ~E_DEPRECATED

; html_errors 
; Default Value: On 
; Development Value: On 
; Production value: Off

; log_errors
; Default Value: On 
; Development Value: On 
; Production Value: On

Search for them as they are already defined and put your desired value. Then restart your apache2 server and everything will work fine. Good luck!

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

TEXT is a data-type for text based input. On the other hand, you have BLOB and CLOB which are more suitable for data storage (images, etc) due to their larger capacity limits (4GB for example).

As for the difference between BLOB and CLOB, I believe CLOB has character encoding associated with it, which implies it can be suited well for very large amounts of text.

BLOB and CLOB data can take a long time to retrieve, relative to how quick data from a TEXT field can be retrieved. So, use only what you need.

iText has more than one way of doing this. The PdfStamper class is one option. But I find the easiest method is to create a new PDF document then import individual pages from the existing document into the new PDF.

// Create output PDF
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();

// Load existing PDF
PdfReader reader = new PdfReader(templateInputStream);
PdfImportedPage page = writer.getImportedPage(reader, 1); 

// Copy first page of existing PDF into output PDF
document.newPage();
cb.addTemplate(page, 0, 0);

// Add your new data / text here
// for example...
document.add(new Paragraph("my timestamp")); 

document.close();

This will read in a PDF from templateInputStream and write it out to outputStream. These might be file streams or memory streams or whatever suits your application.

use json library

import json
json.dumps(list)

by the way, you might consider changing variable list to another name, list is the builtin function for a list creation, you may get some unexpected behaviours or some buggy code if you don't change the variable name.

I have taken this and various other comments and created a bit more advanced function for running an application and getting the output.

Example to Call Function: Will output the DIR list of C:\ for Directories only. The output will be returned to the variable CommandResults as well as remain in C:\OUTPUT.TXT.

CommandResults = vFn_Sys_Run_CommandOutput("CMD.EXE /C DIR C:\ /AD",1,1,"C:\OUTPUT.TXT",0,1)

Function

'Run Command similar to the command prompt, for Wait use 1 or 0. Output returned and
'stored in a file.
'Command = The command line instruction you wish to run.
'Wait = 1/0; 1 will wait for the command to finish before continuing.
'Show = 1/0; 1 will show for the command window.
'OutToFile = The file you wish to have the output recorded to.
'DeleteOutput = 1/0; 1 deletes the output file. Output is still returned to variable.
'NoQuotes = 1/0; 1 will skip wrapping the command with quotes, some commands wont work
'                if you wrap them in quotes.

These days listen for oninput. It feels like onchange without the need to lose focus on the element. It is HTML5.

It’s supported by everyone (even mobile), except IE8 and below. For IE add onpropertychange. I use it like this:

const source = document.getElementById('source');_x000D_
const result = document.getElementById('result');_x000D_
_x000D_
const inputHandler = function(e) {_x000D_
  result.innerHTML = e.target.value;_x000D_
}_x000D_
_x000D_
source.addEventListener('input', inputHandler);_x000D_
source.addEventListener('propertychange', inputHandler); // for IE8_x000D_
// Firefox/Edge18-/IE9+ don’t fire on <select><option>_x000D_
// source.addEventListener('change', inputHandler); 

<input id="source">_x000D_
<div id="result"></div>

self.materials is a dict and by default you are iterating over just the keys (which are strings).

Since self.materials has more than two keys*, they can't be unpacked into the tuple "k, m", hence the ValueError exception is raised.

In Python 2.x, to iterate over the keys and the values (the tuple "k, m"), we use self.materials.iteritems().

However, since you're throwing the key away anyway, you may as well simply iterate over the dictionary's values:

for m in self.materials.itervalues():

In Python 3.x, prefer dict.values() (which returns a dictionary view object):

for m in self.materials.values():

this in div onclick don't have attribute form, you may try this.parentNode.submit() or document.forms[0].submit() will do

Also, onClick, should be onclick, some browsers don't work with onClick

Output: Enter value for n: if you want 2nd highest ,enter 2; if you want 5,enter n=3

ActionListener gets fired first, with an option to modify the response, before Action gets called and determines the location of the next page.

If you have multiple buttons on the same page which should go to the same place but do slightly different things, you can use the same Action for each button, but use a different ActionListener to handle slightly different functionality.

Here is a link that describes the relationship:

http://www.java-samples.com/showtutorial.php?tutorialid=605

If certain position of the string is needed, this code comes to place in Swift 3.0:

let string = "This is my string"
let substring = "my"

let position = string.range(of: substring)?.lowerBound

After try few different ways, i found that if you don't want to use:

let audience = Audience.Public.toRaw()

You can still archive it using a struct

struct Audience {
   static let Public  = "Public"
   static let Friends = "Friends"
   static let Private = "Private"
}

then your code:

let audience = Audience.Public

will work as expected. It isn't pretty and there are some downsides because you not using a "enum", you can't use the shortcut only adding .Private neither will work with switch cases.

I think http makes request on port 80, even though I mentioned the complete host url in options object. When I run the server application which has the API, on port 80, which I was running previously on port 3000, it worked. Note that to run an application on port 80 you will need root privilege.

Error with the request: getaddrinfo EAI_AGAIN localhost:3000:80

Here is a complete code snippet

var http=require('http');

var options = {
  protocol:'http:',  
  host: 'localhost',
  port:3000,
  path: '/iso/country/Japan',
  method:'GET'
};

var callback = function(response) {
  var str = '';

  //another chunk of data has been recieved, so append it to `str`
  response.on('data', function (chunk) {
    str += chunk;
  });

  //the whole response has been recieved, so we just print it out here
  response.on('end', function () {
    console.log(str);
  });
}

var request=http.request(options, callback);

request.on('error', function(err) {
        // handle errors with the request itself
        console.error('Error with the request:', err.message);        
});

request.end();

First globally declare

Context mContext;

pass context with the constructor, by modifying it.

public FeedAdapter(List<Post> myDataset, Context context) {
    mDataset = myDataset;
    this.mContext = context;
}

then use the mContext whereever you need it

If nothing of the above helps, check if there is margin-top set on some of the (some levels below) nested DOM element(s).

It will be not recognizable when you inspect body element itself in the debugger. It will only be visible when you unfold several elements nested down in body element in Chrome Dev Tools elements debugger and check if there is one of them with margin-top set.

The below is the upper part of a site screen shot and the corresponding Chrome Dev Tools view when you inspect body tag.

No sign of top margin here and you have resetted all the browser-scpecific CSS properties as per answers above but that unwanted white space is still here.

The following is a view when you inspect the right nested element. It is clearly seen the orange'ish top-margin is set on it. This is the one that causes the white space on top of body element.

On that found element replace margin-top with padding-top if you need space above it and yet not to leak it above the body tag.

Hope that helps :)

I think you lack to pass Connection object to your command object. and it is much better if you will use command and parameters for that.

using (SqlConnection connection = new SqlConnection("ConnectionStringHere"))
{
    using (SqlCommand command = new SqlCommand())
    {
        command.Connection = connection;            // <== lacking
        command.CommandType = CommandType.Text;
        command.CommandText = "INSERT into tbl_staff (staffName, userID, idDepartment) VALUES (@staffName, @userID, @idDepart)";
        command.Parameters.AddWithValue("@staffName", name);
        command.Parameters.AddWithValue("@userID", userId);
        command.Parameters.AddWithValue("@idDepart", idDepart);

        try
        {
            connection.Open();
            int recordsAffected = command.ExecuteNonQuery();
        }
        catch(SqlException)
        {
            // error here
        }
        finally
        {
            connection.Close();
        }
    }
}

or you can even try executing onClick this (more violent solution):

window.location.assign("/sample");

If the functions are re-written with completely different variables and we call id on them, it then illustrates the point well. I didn't get this at first and read jfs' post with the great explanation, so I tried to understand/convince myself:

def f(y, z):
    y = 2
    z.append(4)
    print ('In f():             ', id(y), id(z))

def main():
    n = 1
    x = [0,1,2,3]
    print ('Before in main:', n, x,id(n),id(x))
    f(n, x)
    print ('After in main:', n, x,id(n),id(x))

main()
Before in main: 1 [0, 1, 2, 3]   94635800628352 139808499830024
In f():                          94635800628384 139808499830024
After in main: 1 [0, 1, 2, 3, 4] 94635800628352 139808499830024

z and x have the same id. Just different tags for the same underlying structure as the article says.

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}

As pointed out already, most standard implementations of List are serializable. However you have to ensure that the objects referenced/contained within the list are also serializable.

You were right in thinking mod was a good place to start. Here is an expression which will return true if $number is even, false if odd:

$number % 2 == 0

Works for every integer^PHP value, see as well Arithmetic Operators^PHP.

Example:

$number = 20;
if ($number % 2 == 0) {
  print "It's even";
}

Output:

It's even

My suggestion is to leverage the hidden/collapse attribute. Try with this example:

<select>
    <option value="echo $row[month]" selected disabled hidden><? echo $row[month] ?></option>
    <option value="1">Jan</option>
    <option value="2">Feb</option>
    <option value="3">Mar</option>
</select>

in case of null for $row[month] the selected item is blank and with data, it would contain less codes for many options and always working for HTML5 and bootstrap etc...

Well, you can actually send data via JavaScript - but you should know that this is the #1 exploit source in web pages as it's XSS :)

I personally would suggest to use an HTML formular instead and modify the javascript data on the server side.

But if you want to share between two pages (I assume they are not both on localhost, because that won't make sense to share between two both-backend-driven pages) you will need to specify the CORS headers to allow the browser to send data to the whitelisted domains.

These two links might help you, it shows the example via Node backend, but you get the point how it works:

Link 1

And, of course, the CORS spec:

Link 2

It's almost always safer to use a library like lodash simply because of all the issues with cross-browser compatibilities and efficiency.

Efficiency because you can be guaranteed that at any given time, a hugely popular library like underscore will have the most efficient method of accomplishing a utility function like this.

_.includes([1, 2, 3], 3); // returns true

If you're concerned about the bulk that's being added to your application by including the whole library, know that you can include functionality separately:

var includes = require('lodash/collections/includes');

NOTICE: With older versions of lodash, this was _.contains() rather than _.includes().

Have you looked at python-graph? I haven't used it myself, but the project page looks promising.

I faced the same problem, it turned out to be VPN related. If you are testing on a device against a corporate network, chances are your Mac has proper VPN set up, but your phone does not. Connect phone to the corporate VPN for your apps deployed to device to see corporate servers.

I found a bug in shermy's vanilla C# 3.5 .NET solution which otherwise works a charm. I have also incorporated Damian Leszczynski - Vash's SecureString idea here but you can use an ordinary string if you prefer.

THE BUG: If you press backspace during the password prompt and the current length of the password is 0 then an asterisk is incorrectly inserted in the password mask. To fix this bug modify the following method.

    public static string ReadPassword(char mask)
    {
        const int ENTER = 13, BACKSP = 8, CTRLBACKSP = 127;
        int[] FILTERED = { 0, 27, 9, 10 /*, 32 space, if you care */ }; // const


        SecureString securePass = new SecureString();

        char chr = (char)0;

        while ((chr = System.Console.ReadKey(true).KeyChar) != ENTER)
        {
            if (((chr == BACKSP) || (chr == CTRLBACKSP)) 
                && (securePass.Length > 0))

                System.Console.Write("\b \b");
                securePass.RemoveAt(securePass.Length - 1);

            }
            // Don't append * when length is 0 and backspace is selected
            else if (((chr == BACKSP) || (chr == CTRLBACKSP)) && (securePass.Length == 0))
            {
            }

            // Don't append when a filtered char is detected
            else if (FILTERED.Count(x => chr == x) > 0)
            {
            }

            // Append and write * mask
            else
            {
                securePass.AppendChar(chr);
                System.Console.Write(mask);
            }
        }

        System.Console.WriteLine();
        IntPtr ptr = new IntPtr();
        ptr = Marshal.SecureStringToBSTR(securePass);
        string plainPass = Marshal.PtrToStringBSTR(ptr);
        Marshal.ZeroFreeBSTR(ptr);
        return plainPass;

The current documentation has a good explanation of what .NET Core is, areas to use and so on. The following characteristics best define .NET Core:

Flexible deployment: Can be included in your app or installed side-by-side user- or machine-wide.

Cross-platform: Runs on Windows, macOS and Linux; can be ported to other OSes. The supported operating systems (OSes), CPUs and application scenarios will grow over time, provided by Microsoft, other companies, and individuals.

Command-line tools: All product scenarios can be exercised at the command-line.

Compatible: .NET Core is compatible with .NET Framework, Xamarin and Mono, via the .NET Standard Library.

Open source: The .NET Core platform is open source, using MIT and Apache 2 licenses. Documentation is licensed under CC-BY. .NET Core is a .NET Foundation project.

Supported by Microsoft: .NET Core is supported by Microsoft, per .NET Core Support

And here is what .NET Core includes:

A .NET runtime, which provides a type system, assembly loading, a garbage collector, native interoperability and other basic services.

A set of framework libraries, which provide primitive data types, application composition types and fundamental utilities.

A set of SDK tools and language compilers that enable the base developer experience, available in the .NET Core SDK.

The 'dotnet' application host, which is used to launch .NET Core applications. It selects the runtime and hosts the runtime, provides an assembly loading policy and launches the app. The same host is also used to launch SDK tools in much the same way.

Best is not using regex for everything. Those requirements are very light. On CPU-wise string operations for checking the criteria/validation is much cheaper and faster than regex!

I see a lot of "Do it this way" but I don't see any answers to "Why?"

So: Why should you @class in your header and #import only in your implementation? You're doubling your work by having to @class and #import all the time. Unless you make use of inheritance. In which case you'll be #importing multiple times for a single @class. Then you have to remember to remove from multiple different files if you suddenly decide you don't need access to a declaration anymore.

Importing the same file multiple times isn't an issue because of the nature of #import. Compiling performance isn't really an issue either. If it were, we wouldn't be #importing Cocoa/Cocoa.h or the like in pretty much every header file we have.

One-to-Many: One Person Has Many Skills, a Skill is not reused between Person(s)

• Unidirectional: A Person can directly reference Skills via its Set
• Bidirectional: Each "child" Skill has a single pointer back up to the Person (which is not shown in your code)

Many-to-Many: One Person Has Many Skills, a Skill is reused between Person(s)

• Unidirectional: A Person can directly reference Skills via its Set
• Bidirectional: A Skill has a Set of Person(s) which relate to it.

In a One-To-Many relationship, one object is the "parent" and one is the "child". The parent controls the existence of the child. In a Many-To-Many, the existence of either type is dependent on something outside the both of them (in the larger application context).

Your subject matter (domain) should dictate whether or not the relationship is One-To-Many or Many-To-Many -- however, I find that making the relationship unidirectional or bidirectional is an engineering decision that trades off memory, processing, performance, etc.

What can be confusing is that a Many-To-Many Bidirectional relationship does not need to be symmetric! That is, a bunch of People could point to a skill, but the skill need not relate back to just those people. Typically it would, but such symmetry is not a requirement. Take love, for example -- it is bi-directional ("I-Love", "Loves-Me"), but often asymmetric ("I love her, but she doesn't love me")!

All of these are well supported by Hibernate and JPA. Just remember that Hibernate or any other ORM doesn't give a hoot about maintaining symmetry when managing bi-directional many-to-many relationships...thats all up to the application.

You could make it into a module and expose your inner function by returning it in an Object.

function outer() { 
    function inner() {
        console.log("hi");
    }
    return {
        inner: inner
    };
}
var foo = outer();
foo.inner();

I had a similar issue but I was missing the (@Service or @Component) from the implementation of com.example.my.services.myUser.MyUserServiceImpl

Easiest way to see if the file is being cached is to append a query string to the <link /> element so that the browser will re-load it.

To do this you can change your stylesheet reference to something like

<link rel="stylesheet" type="text/css" href="/css/stylesheet.css?v=1" />

Note the v=1 part. You can update this each time you make a new version to see if it is indeed being cached.

You have several options:

1. Use the standard FB Share button and set text via Open Graph API and meta tags on your page.
2. Instead of Share, use FB.ui's stream.publish method, which let's you control the URL, title, caption, description and thumbnail at run-time.
3. Or use http://www.facebook.com/sharer.php with appropriate parameters.

This command would work perfectly fine :D

sudo -H pip install --upgrade package_name --ignore-installed six

Instance variables or fields, along with static variables, are assigned default values based on the variable type:

• int: 0
• char: \u0000 or 0
• double: 0.0
• boolean: false
• reference: null

Just want to clarify that local variables (ie. declared in block, eg. method, for loop, while loop, try-catch, etc.) are not initialized to default values and must be explicitly initialized.

Just weighing in here with a nice solution I have been using. This is similar to Lucky Soni's solution above in that it supports aggregation, but doesn't require hard coding of the field names.

cursor = db.<collection_name>.<my_query_with_aggregation>;

headerPrinted = false;
while (cursor.hasNext()) {
    item = cursor.next();
    
    if (!headerPrinted) {
        print(Object.keys(item).join(','));
        headerPrinted = true;
    }

    line = Object
        .keys(item)
        .map(function(prop) {
            return '"' + item[prop] + '"';
        })
        .join(',');
    print(line);
}

Save this as a .js file, in this case we'll call it example.js and run it with the mongo command line like so:

mongo <database_name> example.js --quiet > example.csv

I had the same problem you had. I used a for loop with the sorted function passing in the dictionary like so:

for item in sorted(mydict):
    print(item)

Get-Location will return the current location:

$Currentlocation = Get-Location

On OS X, choose "Document Format", and select all lines that you need format.

Then Option + Shift + F.

An addendum to this. You can use character entities (such as changing <div> to <div>) and it will render in the textarea. But when it is saved, the value of the textarea is the text as rendered. So you don't need to de-encode. I just tested this across browsers (ie back to 11).

I have faced the same issue. Try declaring missing plugin in the conf/settings.xml.

<build>
    <pluginManagement>
      <plugins>
        <plugin>
          <artifactId>maven-resources-plugin</artifactId>
          <version>2.6</version>
        </plugin>           
      </plugins>
    </pluginManagement>   
</build>

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

I just had this problem and resolved it by adding the namespace to the service name, e.g.

 <service name="TechResponse">

became

 <service name="SvcClient.TechResponse">

I've also seen it resolved with a Web.config instead of an App.config.

You can also use Projections:

ProjectionList projection = Projections.projectionList();
projection.add(Projections.rowCount());
criteria.setProjection(projection);

Long totalRows = (Long) criteria.list().get(0);

You could do it in one document if you had a conditional based on params sent over. Eg:

if (isset($_GET['secret_param'])) {
    <run script>
} else {
    <display button>
}

I think the best way though is to have two files.

Use os.chdir to change directory . Use glob.glob to generate a list of file names which end it '.bak'. The elements of the list are just strings.

Then you could use os.unlink to remove the files. (PS. os.unlink and os.remove are synonyms for the same function.)

#!/usr/bin/env python
import glob
import os
directory='/path/to/dir'
os.chdir(directory)
files=glob.glob('*.bak')
for filename in files:
    os.unlink(filename)

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

As Peter Mortensen wrote:

In the Visual Studio 2005 menu:

Debug -> New Breakpoint -> New Data Breakpoint

Enter: &myVariable

Additional information:

Obviously, the system must know which address in memory to watch. So - set a normal breakpoint to the initialisation of myVariable (or myClass.m_Variable) - run the system and wait till it stops at that breakpoint. - Now the Menu entry is enabled, and you can watch the variable by entering &myVariable, or the instance by entering &myClass.m_Variable. Now the addresses are well defined.

Sorry when I did things wrong by explaining an already given solution. But I could not add a comment, and there has been some comments regarding this.

You can use the following to programmatically center TextView text in Kotlin:

textview.gravity = Gravity.CENTER

To dump database using shell_exec(), below is the method :

shell_exec('mysqldump -h localhost -u username -ppassword databasename  | gzip > dbname.sql.gz');

I did the same that user9876226 answered. The only differemce is, that I don't usually use the onClickListener. Instead I write following in the xml-file: android:onClick="open"

open is the function, that is bound to the button. Then just create the function open() in your activity class. When you click on the button, this function will be called :) Also, I think this way is more confortable than using the listener.

And using ports:

port install gradle

Ports , tested on El Capitan

In PostgeSql you can check for indexes yourself if you hit \d tablename

You will see that btree indexes have been automatically created on columns with primary key and unique constraints, but not on columns with foreign keys.

I think that answers your question at least for postgres.

Be sure to serve up the file without a no-cache header! IE has issues with this, if user tries to "open" the download without saving first.

If you really need to be sure that now() has the same value you can run two queries (that will answer to your second question too, in that case you are asking to update last_monitor = to last_update but last_update hasn't been updated yet)

you could do something like:

mysql> update table set last_update=now() where id=1;
mysql> update table set last_monitor = last_update where id=1;

anyway I think that mysql is clever enough to ask for now() only once per query.

You do not have to call parseJSON since the output of json_encode is a javascript literal. Just assign it to a js variable.

<script type="text/javascript">
    //Assign php generated json to JavaScript variable
    var tempArray = <?php echo json_encode($php_array); ?>;

   //You will be able to access the properties as 
    alert(tempArray[0].Key);
</script>

User felixhummel got very good solution, but repository with utilite has changed.

A tar.gz is a tar file inside a gzip file, so 1st you must unzip the gzip file with gunzip -d filename.tar.gz , and then use tar to untar it. However, since gunzip says it isn't in gzip format, you can see what format it is in with file filename.tar.gz, and use the appropriate program to open it.

To add to Lauritz's answer, I created a decorator/wrapper for exception handling and the wrapper logs which type of exception occurred.

class general_function_handler(object):
    def __init__(self, func):
        self.func = func
    def __get__(self, obj, type=None):
        return self.__class__(self.func.__get__(obj, type))
    def __call__(self, *args, **kwargs):
        try:
            retval = self.func(*args, **kwargs)
        except Exception, e :
            logging.warning('Exception in %s' % self.func)
            template = "An exception of type {0} occured. Arguments:\n{1!r}"
            message = template.format(type(e).__name__, e.args)
            logging.exception(message)
            sys.exit(1) # exit on all exceptions for now
        return retval

This can be called on a class method or a standalone function with the decorator:

@general_function_handler

See my blog about for the full example: http://ryaneirwin.wordpress.com/2014/05/31/python-decorators-and-exception-handling/

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

Sometimes you need to work with adjustments.

Don't use cast to long! Use nanoadjustment.

For example, using Oanda Java API for trading you can get datetime as UNIX format.

For example: 1592523410.590566943

    System.out.println("instant with nano = " + Instant.ofEpochSecond(1592523410, 590566943));
    System.out.println("instant = " + Instant.ofEpochSecond(1592523410));

you get:

instant with nano = 2020-06-18T23:36:50.590566943Z
instant = 2020-06-18T23:36:50Z

Also, use:

 Date date = Date.from( Instant.ofEpochSecond(1592523410, 590566943) );

You need to make sure the IIS Management Console is installed.

The git.exe from Github for windows is located in a path like C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\bin\git.exe1 You have to replace <username> and <numbersandletters> to the actual situation on your system.

In Android Studio you can specify the path to the Git executable at File->Settings...->Version Control->Git->Path to Git executable. Here you have to include the actual executable name. As an example, in my case the actual path is: C:\Users\dennis\AppData\Local\GitHub\PortableGit_69703d1db91577f4c666e767a6ca5ec50a48d243\bin\git.exe

Edit: Last git update has put the git.exe file in cmd\ folder instead of bin\ . so now the actual path will be as suggested in the comment below by al3xAndr3w.

C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\cmd\git.exe

I've your same requirements on a public API for which I used rails-api.

I've also set header in a before filter. It looks like this:

headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'

It seems you missed the Access-Control-Request-Method header.

Since Python 3.3, you can use the class ExitStack from the contextlib module.

It can manage a dynamic number of context-aware objects, which means that it will prove especially useful if you don't know how many files you are going to handle.

The canonical use-case that is mentioned in the documentation is managing a dynamic number of files.

with ExitStack() as stack:
    files = [stack.enter_context(open(fname)) for fname in filenames]
    # All opened files will automatically be closed at the end of
    # the with statement, even if attempts to open files later
    # in the list raise an exception

Here is a generic example:

from contextlib import ExitStack

class X:
    num = 1

    def __init__(self):
        self.num = X.num
        X.num += 1

    def __repr__(self):
        cls = type(self)
        return '{cls.__name__}{self.num}'.format(cls=cls, self=self)

    def __enter__(self):
        print('enter {!r}'.format(self))
        return self.num

    def __exit__(self, exc_type, exc_value, traceback):
        print('exit {!r}'.format(self))
        return True

xs = [X() for _ in range(3)]

with ExitStack() as stack:
    print(stack._exit_callbacks)
    nums = [stack.enter_context(x) for x in xs]
    print(stack._exit_callbacks)
print(stack._exit_callbacks)
print(nums)

Output:

deque([])
enter X1
enter X2
enter X3
deque([<function ExitStack._push_cm_exit.<locals>._exit_wrapper at 0x7f5c95f86158>, <function ExitStack._push_cm_exit.<locals>._exit_wrapper at 0x7f5c95f861e0>, <function ExitStack._push_cm_exit.<locals>._exit_wrapper at 0x7f5c95f86268>])
exit X3
exit X2
exit X1
deque([])
[1, 2, 3]

It is possible to use the data field name, if not the title so easily, which solved the problem for me. For ASP.NET & VB:

e.g. For a string:

Dim Encoding = e.Row.DataItem("Encoding").ToString().Trim()

e.g. For an integer:

Dim MsgParts = Convert.ToInt32(e.Row.DataItem("CalculatedMessageParts").ToString())

If they're meant to be separate values, try this:

var values = "554,20".split(",")
var v1 = parseFloat(values[0])
var v2 = parseFloat(values[1])

If they're meant to be a single value (like in French, where one-half is written 0,5)

var value = parseFloat("554,20".replace(",", "."));

Use the 'merge' step of merge sort, it runs in O(n) time.

From wikipedia (pseudo-code):

function merge(left,right)
    var list result
    while length(left) > 0 and length(right) > 0
        if first(left) = first(right)
            append first(left) to result
            left = rest(left)
        else
            append first(right) to result
            right = rest(right)
    end while
    while length(left) > 0 
        append left to result
    while length(right) > 0 
        append right to result
    return result

Another solution:

Based on the document, Boolean object will return true if the value is not 0, undefined, null, etc. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean

If value is omitted or is 0, -0, null, false, NaN, undefined, or the empty string (""), the object has an initial value of false.

So

if(Boolean(val))
{
//executable...
}

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Caseyjustus comment helped me. Apparently I had space in my require path.

const listingController = require("../controllers/ listingController");

I changed my code to

const listingController = require("../controllers/listingController");

and everything was fine.

You haven't shown your Car type, but assuming you'd want the price of the first car, you could use:

public static void processCars(ArrayList<Car> cars) {
    Car car = cars.get(0);
    System.out.println(car.getPrice());
}

Note that I've changed the name of the list from car to cars - this is a list of cars, not a single car. (I've changed the method name in a similar way.)

If you only want the method to process a single car, you should change the parameter to be of type Car:

public static void processCar(Car car)

and then call it like this:

// In the main method
processCar(cars.get(0));

If you do leave it as processing the whole list, it would be worth generalizing the parameter to List<Car> - it's unlikely that you'll really require that it's an ArrayList<Car>.

This solution appears better to me, regarding maintainability and design for change:

1. Create the logging property file embedding it in the resource project folder, to be included in the jar file:

   # Logging
   handlers = java.util.logging.ConsoleHandler
   .level = ALL
   
   # Console Logging
   java.util.logging.ConsoleHandler.level = ALL
   

2. Load the property file from code:

   public static java.net.URL retrieveURLOfJarResource(String resourceName) {
      return Thread.currentThread().getContextClassLoader().getResource(resourceName);
   }
   
   public synchronized void initializeLogger() {
      try (InputStream is = retrieveURLOfJarResource("logging.properties").openStream()) {
         LogManager.getLogManager().readConfiguration(is);
      } catch (IOException e) {
         // ...
      }
   }
   

I would like to suggest to use a single RecyclerView and populate your list items dynamically. I've added a github project to describe how this can be done. You might have a look. While the other solutions will work just fine, I would like to suggest, this is a much faster and efficient way of showing multiple lists in a RecyclerView.

The idea is to add logic in your onCreateViewHolder and onBindViewHolder method so that you can inflate proper view for the exact positions in your RecyclerView.

I've added a sample project along with that wiki too. You might clone and check what it does. For convenience, I am posting the adapter that I have used.

public class DynamicListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int FOOTER_VIEW = 1;
    private static final int FIRST_LIST_ITEM_VIEW = 2;
    private static final int FIRST_LIST_HEADER_VIEW = 3;
    private static final int SECOND_LIST_ITEM_VIEW = 4;
    private static final int SECOND_LIST_HEADER_VIEW = 5;

    private ArrayList<ListObject> firstList = new ArrayList<ListObject>();
    private ArrayList<ListObject> secondList = new ArrayList<ListObject>();

    public DynamicListAdapter() {
    }

    public void setFirstList(ArrayList<ListObject> firstList) {
        this.firstList = firstList;
    }

    public void setSecondList(ArrayList<ListObject> secondList) {
        this.secondList = secondList;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        // List items of first list
        private TextView mTextDescription1;
        private TextView mListItemTitle1;

        // List items of second list
        private TextView mTextDescription2;
        private TextView mListItemTitle2;

        // Element of footer view
        private TextView footerTextView;

        public ViewHolder(final View itemView) {
            super(itemView);

            // Get the view of the elements of first list
            mTextDescription1 = (TextView) itemView.findViewById(R.id.description1);
            mListItemTitle1 = (TextView) itemView.findViewById(R.id.title1);

            // Get the view of the elements of second list
            mTextDescription2 = (TextView) itemView.findViewById(R.id.description2);
            mListItemTitle2 = (TextView) itemView.findViewById(R.id.title2);

            // Get the view of the footer elements
            footerTextView = (TextView) itemView.findViewById(R.id.footer);
        }

        public void bindViewSecondList(int pos) {

            if (firstList == null) pos = pos - 1;
            else {
                if (firstList.size() == 0) pos = pos - 1;
                else pos = pos - firstList.size() - 2;
            }

            final String description = secondList.get(pos).getDescription();
            final String title = secondList.get(pos).getTitle();

            mTextDescription2.setText(description);
            mListItemTitle2.setText(title);
        }

        public void bindViewFirstList(int pos) {

            // Decrease pos by 1 as there is a header view now.
            pos = pos - 1;

            final String description = firstList.get(pos).getDescription();
            final String title = firstList.get(pos).getTitle();

            mTextDescription1.setText(description);

There is another way of keeping your items in a single ArrayList of objects so that you can set an attribute tagging the items to indicate which item is from first list and which one belongs to second list. Then pass that ArrayList into your RecyclerView and then implement the logic inside adapter to populate them dynamically.

Hope that helps.

i've found one solution:

$("#someElement")[0].className.match("test")

but somehow i believe that there's a better way!

Following worked on M1

ProductName:    macOS
ProductVersion: 11.2.1
BuildVersion:   20D74

% xcode-select --install

Agree the Terms and Conditions prompt, it will return following message on success.

% xcode-select: note: install requested for command line developer tools

Give it a chance:

Try getting string via function gets(string) then check condition as if(string[0] == '\0')

According to PHPMailer Manual, full answer would be :

$mail->AddEmbeddedImage(filename, cid, name);
//Example
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg '); 

Use Case :

$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Embedded Image: <img alt="PHPMailer" src="cid:my-attach"> Here is an image!';

If you want to display an image with a remote URL :

$mail->addStringAttachment(file_get_contents("url"), "filename");

If I'm not mistaken you're looking for the FolderBrowserDialog (hence the naming):

var dialog = new System.Windows.Forms.FolderBrowserDialog();
System.Windows.Forms.DialogResult result = dialog.ShowDialog();

Also see this SO thread: Open directory dialog

I was looking for something like this and after some tries and falls i create my own makefile, I know that's not the "idiomatic way" but it's a begining to understand make and this works for me, maybe you could try in your project.

PROJ_NAME=mono

CPP_FILES=$(shell find . -name "*.cpp")

S_OBJ=$(patsubst %.cpp, %.o, $(CPP_FILES))

CXXFLAGS=-c \
         -g \
        -Wall

all: $(PROJ_NAME)
    @echo Running application
    @echo
    @./$(PROJ_NAME)

$(PROJ_NAME): $(S_OBJ)
    @echo Linking objects...
    @g++ -o $@ $^

%.o: %.cpp %.h
    @echo Compiling and generating object $@ ...
    @g++ $< $(CXXFLAGS) -o $@

main.o: main.cpp
    @echo Compiling and generating object $@ ...
    @g++ $< $(CXXFLAGS)

clean:
    @echo Removing secondary things
    @rm -r -f objects $(S_OBJ) $(PROJ_NAME)
    @echo Done!

I know that's simple and for some people my flags are wrong, but as i said this is my first Makefile to compile my project in multiple dirs and link all of then together to create my bin.

I'm accepting sugestions :D

What about this solution? It does not rely on knowledge of @staticmethod decorator implementation. Inner class StaticMethod plays as a container of static initialization functions.

class Klass(object):

    class StaticMethod:
        @staticmethod  # use as decorator
        def _stat_func():
            return 42

    _ANS = StaticMethod._stat_func()  # call the staticmethod

    def method(self):
        ret = self.StaticMethod._stat_func() + Klass._ANS
        return ret

This is how I would do it, in order to get in the var4 restriction:

dfr<-data.frame(var1=rnorm(100), var2=rnorm(100), var3=rnorm(100, 160, 10), var4=rnorm(100, 27, 6))
plot( subset( dfr, var3 < 155 & var4 > 27, select = c( var1, var2 ) ) )

Rgds, Rainer

$foo = 42;
$bar = function($x = 0) use ($foo){
    return $x + $foo;
};
var_dump($bar(10)); // int(52)

UPDATE: there is now support for arrow functions, but i will let for someone that used it more to create the answer

To build on the previous answer if you add -f you can tail the logs.

kubectl logs -f deployment/app

Try this:

import java.util.*;

public class SimpleCacheManager {

    private static SimpleCacheManager instance;
    private static Object monitor = new Object();
    private Map<String, Object> cache = Collections.synchronizedMap(new HashMap<String, Object>());

    private SimpleCacheManager() {
    }

    public void put(String cacheKey, Object value) {
        cache.put(cacheKey, value);
    }

    public Object get(String cacheKey) {
        return cache.get(cacheKey);
    }

    public void clear(String cacheKey) {
        cache.put(cacheKey, null);
    }

    public void clear() {
        cache.clear();
    }

    public static SimpleCacheManager getInstance() {
        if (instance == null) {
            synchronized (monitor) {
                if (instance == null) {
                    instance = new SimpleCacheManager();
                }
            }
        }
        return instance;
    }

}

I had a similar challenge, but in my case, we had developed one version of the codebase in repo A, then cloned that into a new repo, repo B, for the new version of the product. After fixing some bugs in repo A, we needed to FI the changes into repo B. Ended up doing the following:

1. Adding a remote to repo B that pointed to repo A (git remote add...)
2. Pulling the current branch (we were not using master for bug fixes) (git pull remoteForRepoA bugFixBranch)
3. Pushing merges to github

Worked a treat :)

I got the same problem, and the solution is very simple: don't start a new line! Although some of the previous answers can solve the problem, the idea is not stated clearly. The important understanding is, to get rid of the unintended spaces, never start a new line just after your start tag.

The following way is WRONG and will leave a lot of unwanted spaces before your text content:

 <textarea>
    text content // start with a new line will leave a lot of unwanted spaces
 </textarea>

The RIGHT WAY to do it is:

 <textarea>text content //put text content right after your start tag, no new line
 </textarea>

Install the Eclipse Metrics Plugin. To create a HTML report (with optional XML and CSV) right-click a project -> Export -> Other -> Metrics.

You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want. To do this check the tab at Preferences -> Metrics -> LoC.

That's it. There is no special option to exclude curly braces {}.

The plugin offers an alternative metric to LoC called Number of Statements. This is what the author has to say about it:

This metric represents the number of statements in a method. I consider it a more robust measure than Lines of Code since the latter is fragile with respect to different formatting conventions.

Edit:

After you clarified your question, I understand that you need a view for real-time metrics violations, like compiler warnings or errors. You also need a reporting functionality to create reports for your boss. The plugin I described above is for reporting because you have to export the metrics when you want to see them.

there's also ndisasm, which has some quirks, but can be more useful if you use nasm. I agree with Michael Mrozek that objdump is probably best.

[later] you might also want to check out Albert van der Horst's ciasdis: http://home.hccnet.nl/a.w.m.van.der.horst/forthassembler.html. it can be hard to understand, but has some interesting features you won't likely find anywhere else.

It looks OK apart from the space in your ID attribute, which is not valid, and the fact that you're replacing the value of your input before checking the selection.

function textbox()_x000D_
{_x000D_
        var ctl = document.getElementById('Javascript_example');_x000D_
        var startPos = ctl.selectionStart;_x000D_
        var endPos = ctl.selectionEnd;_x000D_
        alert(startPos + ", " + endPos);_x000D_
}

<input id="Javascript_example" name="one" type="text" value="Javascript example" onclick="textbox()">

Also, if you're supporting IE <= 8 you need to be aware that those browsers do not support selectionStart and selectionEnd.

function file_get_ext(filename)
    {
    return typeof filename != "undefined" ? filename.substring(filename.lastIndexOf(".")+1, filename.length).toLowerCase() : false;
    }

The simplest method is

$dateArray = explode('/', $_POST['date']);
$date = $dateArray[2].'-'.$dateArray[0].'-'.$dateArray[1];

$sql = mysql_query("INSERT INTO user_date (column,column,column) VALUES('',$name,$date)") or die (mysql_error());

You should be able to use something similar to:

$('#selectElementId').change(
    function(){
         $(this).closest('form').trigger('submit');
         /* or:
         $('#formElementId').trigger('submit');
            or:
         $('#formElementId').submit();
         */
    });

find -name "*Robert*" \( -name "*.pdf" -o -name "*.jpg" \)

The -o repreents an OR condition and you can add as many as you wish within the braces. So this says to find all files containing the word "Robert" anywhere in their names and whose names end in either "pdf" or "jpg".

With Java 8, you can use format method..: -

System.out.format("%.2f", 4.0); // OR

System.out.printf("%.2f", 4.0); 

• f is used for floating point value..
• 2 after decimal denotes, number of decimal places after .

For most Java versions, you can use DecimalFormat: -

    DecimalFormat formatter = new DecimalFormat("#0.00");
    double d = 4.0;
    System.out.println(formatter.format(d));

Probably the simplest way is to use the InputBox method of the Microsoft.VisualBasic.Interaction class:

[void][Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')

$title = 'Demographics'
$msg   = 'Enter your demographics:'

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title)

Try putting the e.Row.Cells[0].Visible = false; inside the RowCreated event of your grid.

protected void bla_RowCreated(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[0].Visible = false; // hides the first column
}

This way it auto-hides the whole column.

You don't have access to the generated columns through grid.Columns[i] in your gridview's DataBound event.

In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.

Example:

select * from table order by [some_column] 
offset 10 rows
FETCH NEXT 10 rows only

And you can't use the "TOP" keyword when doing this.

There are on average, roughly 365.2425 days in a year at the moment (the Earth is slowing down but let's ignore that for now).

The reason we have leap years every 4 years is because that gets us to 365.25 on average [(365+365+365+366) / 4 = 365.25, 1461 days in 4 years].

The reason we don't have leap years on the 100-multiples is to get us to 365.24 `[(1461 x 25 - 1) / 100 = 365.24, 36,524 days in 100 years.

Then the reason we once again have a leap year on 400-multiples is to get us to 365.2425 [(36,524 x 4 + 1) / 400 = 365.2425, 146,097 days in 400 years].

I believe there may be another rule at 3600-multiples but I've never coded for it (Y2K was one thing but planning for one and a half thousand years into the future is not necessary in my opinion - keep in mind I've been wrong before).

So, the rules are, in decreasing priority:

• multiple of 400 is a leap year.
• multiple of 100 is not a leap year.
• multiple of 4 is a leap year.
• anything else is not a leap year.

The default MidpointRounding.ToEven, or Bankers' rounding (2.5 become 2, 4.5 becomes 4 and so on) has stung me before with writing reports for accounting, so I'll write a few words of what I found out, previously and from looking into it for this post.

Who are these bankers that are rounding down on even numbers (British bankers perhaps!)?

From wikipedia

The origin of the term bankers' rounding remains more obscure. If this rounding method was ever a standard in banking, the evidence has proved extremely difficult to find. To the contrary, section 2 of the European Commission report The Introduction of the Euro and the Rounding of Currency Amounts suggests that there had previously been no standard approach to rounding in banking; and it specifies that "half-way" amounts should be rounded up.

It seems a very strange way of rounding particularly for banking, unless of course banks use to receive lots of deposits of even amounts. Deposit £2.4m, but we'll call it £2m sir.

The IEEE Standard 754 dates back to 1985 and gives both ways of rounding, but with banker's as the recommended by the standard. This wikipedia article has a long list of how languages implement rounding (correct me if any of the below are wrong) and most don't use Bankers' but the rounding you're taught at school:

• C/C++ round() from math.h rounds away from zero (not banker's rounding)
• Java Math.Round rounds away from zero (it floors the result, adds 0.5, casts to an integer). There's an alternative in BigDecimal
• Perl uses a similar way to C
• Javascript is the same as Java's Math.Round.

I know it's an old thread, but here's my experience getting it resolved.

My server is a hosted service running Apache.

My script crashed with out of memory at 6Mb, when my limit Was 256Mb - crazy, yeah?

It is being called synchronously via an http callback, from javascript running on my client, and crashed after around 550 calls. After much time wasted with incompetent "Escalated Support" guys, my script now magically runs.

They said all they did was to reset php.ini, but I checked the differences:

No changes there that I can see that could have a bearing on an Out of Memory error.

I suspect a memory leak in the web server which my "Escalated Support" guy is hiding under the guise of resetting the php.ini. And, really, I'm not a conspiracy theorist.

If you want to use the GUI... click/double-click the table and select the Data tab. Click in the column value you want to set to (null). Select the value and delete it. Hit the commit button (green check-mark button). It should now be null.

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

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

Despite the imprecise nature of the question, here's my interpretive answer.

var html = [
    '<div> A line</div>',
    '<div> Add more lines</div>',
    '<div> To the array as you need.</div>'
].join('');

var div = document.createElement('div');
    div.setAttribute('class', 'post block bc2');
    div.innerHTML = html;
    document.getElementById('posts').appendChild(div);

FFMpeg can do this by seeking to the given timestamp and extracting exactly one frame as an image, see for instance:

ffmpeg -i input_file.mp4 -ss 01:23:45 -vframes 1 output.jpg

Let's explain the options:

-i input file           the path to the input file
-ss 01:23:45            seek the position to the specified timestamp
-vframes 1              only handle one video frame
output.jpg              output filename, should have a well-known extension

The -ss parameter accepts a value in the form HH:MM:SS[.xxx] or as a number in seconds. If you need a percentage, you need to compute the video duration beforehand.

I don't know of any git command that gives a "bad" exit code, but it seems like an easy way to do it would be to use a git command that gives no output for a file that isn't tracked, such as git-log or git-ls-files. That way you don't really have to do any parsing, you can run it through another simple utility like grep to see if there was any output.

For example,

git-ls-files test_file.c | grep .

will exit with a zero code if the file is tracked, but a exit code of one if the file is not tracked.

plt.savefig("circle.png", bbox_inches='tight',pad_inches=-1)

if you installed its this way(if you not, installing this way):

pip install beautifulsoup4

and if you used its this code(if you not, use this code):

from bs4 import BeautifulSoup

if you using windows system, check it if there are module, might saved different path its module

I agree that Amazon appears to be intentionally obfuscating even how to find the API documentation, as well as use it. I'm just speculating though.

Renaming the services from "ECS" to "Product Advertising API" was probably also not the best move, it essentially invalidated all that Google mojo they had built up over time.

It took me quite a while to 'discover' this updated link for the Product Advertising API. I don't remember being able to easily discover it through the typical 'Developer' link on the Amazon webpage. This documentation appears to valid and what I've worked from recently.

The change to authentication procedures also seems to add further complexity, but I'm sure they have a reason for it.

I use SOAP via C# to communicate with Amazon Product API.

With the REST API you have to encrypt the whole URL in a fairly specific way. The params have to be sorted, etc. There is just more to do. With the SOAP API, you just encrypt the operation+timestamp, and thats it.

Adam O'Neil's post here, How to get album, dvd, and blueray cover art from Amazon, walks through the SOAP with C# method. Its not the original sample I pulled down, and contrary to his comment, it was not an official Amazon sample I stumbled on, though the code looks identical. However, Adam does a good job at presenting all the necessary steps. I wish I could credit the original author.

They have the same speed. Maybe in some special architecture what he/she said is right, but in the x86 family at least I know they are the same. Because for doing this the CPU will do a substraction (a - b) and then check the flags of the flag register. Two bits of that register are called ZF (zero Flag) and SF (sign flag), and it is done in one cycle, because it will do it with one mask operation.

I don't suggest you to use syntax like you did. AngularJs lets you to have different functionalities as you want (run, config, service, factory, etc..), which are more professional.In this function you don't even have to inject that by yourself like

MainCtrl.$inject = ['$scope', '$rootScope', '$location', 'socket', ...];

you can use it, as you know.

The BOM is generated by, say, File.WriteAllText() or StreamWriter when you don't specify an Encoding. The default is to use the UTF8 encoding and generate a BOM. You can tell the java compiler about this with its -encoding command line option.

The path of least resistance is to avoid generating the BOM. Do so by specifying System.Text.Encoding.Default, that will write the file with the characters in the default code page of your operating system and doesn't write a BOM. Use the File.WriteAllText(String, String, Encoding) overload or the StreamWriter(String, Boolean, Encoding) constructor.

Just make sure that the file you create doesn't get compiled by a machine in another corner of the world. It will produce mojibake.

On the order of DOM events: CAPTURING vs BUBBLING

There are two stages for how events propagate. These are called "capturing" and "bubbling".

               | |                                   / \
---------------| |-----------------   ---------------| |-----------------
| element1     | |                |   | element1     | |                |
|   -----------| |-----------     |   |   -----------| |-----------     |
|   |element2  \ /          |     |   |   |element2  | |          |     |
|   -------------------------     |   |   -------------------------     |
|        Event CAPTURING          |   |        Event BUBBLING           |
-----------------------------------   -----------------------------------

The capturing stage happen first, and are then followed by the bubbling stage. When you register an event using the regular DOM api, the events will be part of the bubbling stage by default, but this can be specified upon event creation

// CAPTURING event
button.addEventListener('click', handleClick, true)

// BUBBLING events
button.addEventListener('click', handleClick, false)
button.addEventListener('click', handleClick)

In React, bubbling events are also what you use by default.

// handleClick is a BUBBLING (synthetic) event
<button onClick={handleClick}></button>

// handleClick is a CAPTURING (synthetic) event
<button onClickCapture={handleClick}></button>

Let's take a look inside our handleClick callback (React):

function handleClick(e) {
  // This will prevent any synthetic events from firing after this one
  e.stopPropagation()
}

function handleClick(e) {
  // This will set e.defaultPrevented to true
  // (for all synthetic events firing after this one)
  e.preventDefault()  
}

An alternative that I haven't seen mentioned here

If you call e.preventDefault() in all of your events, you can check if an event has already been handled, and prevent it from being handled again:

handleEvent(e) {
  if (e.defaultPrevented) return  // Exits here if event has been handled
  e.preventDefault()

  // Perform whatever you need to here.
}

For the difference between synthetic events and native events, see the React documentation: https://reactjs.org/docs/events.html

public void Method()
{
    if(something)
    {
        //some code
        if(something2)
        {
            // The code i want to go if the second if is true
        }
    return;
    }
}

There are a few things to keep in mind while declaring primitive type values.

They are:

1. Values declared inside a method will not be assigned a default value.
2. Values declared as instance variables or a static variable will have default values assigned which is 0.

So in your code:

public class Main {
    int instanceVariable;
    static int staticVariable;
    public static void main(String[] args) {
        Main mainInstance = new Main()
        int localVariable;
        int localVariableTwo = 2;
        System.out.println(mainInstance.instanceVariable);
        System.out.println(staticVariable);
       // System.out.println(localVariable); // Will throw a compilation error
        System.out.println(localVariableTwo);
    }
}

Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:

sep=,

Now open it with excel again.

This will set the separator as a comma, or you can change it to whatever you need.

Simply ...........

As 2's complement of any number we can calculate by inverting all 1s to 0's and vice-versa than we add 1 to it..

Here N= ~N produce results -(N+1) always. Because system store data in form of 2's complement which means it stores ~N like this.

  ~N = -(~(~N)+1) =-(N+1). 

For example::

  N = 10  = 1010
  Than ~N  = 0101
  so ~(~N) = 1010
  so ~(~N) +1 = 1011 

Now point is from where Minus comes. My opinion is suppose we have 32 bit register which means 2^31 -1 bit involved in operation and to rest one bit which change in earlier computation(complement) stored as sign bit which is 1 usually. And we get result as ~10 = -11.

~(-11) =10 ;

The above is true if printf("%d",~0); we get result: -1;

But printf("%u",~0) than result: 4294967295 on 32 bit machine.

@param is a special format comment used by javadoc to generate documentation. it is used to denote a description of the parameter (or parameters) a method can receive. there's also @return and @see used to describe return values and related information, respectively:

http://www.oracle.com/technetwork/java/javase/documentation/index-137868.html#format

has, among other things, this:

/**
 * Returns an Image object that can then be painted on the screen. 
 * The url argument must specify an absolute {@link URL}. The name
 * argument is a specifier that is relative to the url argument. 
 * <p>
 * This method always returns immediately, whether or not the

I think your second option is the best bet. Generally in floating-point comparison you often only care that one value is within a certain tolerance of another value, controlled by the selection of epsilon.

The solution for me was to install the oracle unlimited JCE and install in JRE_HOME/lib/security. Then restarted glassfish and I was able to connect to my sftp server using jsch.

Change Color and Value ( instant change )

Put using System.Runtime.InteropServices; at top...

Call with ColorBar.SetState(progressBar1, ColorBar.Color.Yellow, myValue);

I noticed that if you change the value of the bar ( how big it is ) then it will not change if it is in a color other than the default green. I took user1032613's code and added a Value option.

public static class ColorBar
{
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
    static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr w, IntPtr l);
    public enum Color { None, Green, Red, Yellow }

    public static void SetState(this ProgressBar pBar, Color newColor, int newValue)
    {
        if (pBar.Value == pBar.Minimum)  // If it has not been painted yet, paint the whole thing using defualt color...
        {                                // Max move is instant and this keeps the initial move from going out slowly 
            pBar.Value = pBar.Maximum;   // in wrong color on first painting
            SendMessage(pBar.Handle, 1040, (IntPtr)(int)Color.Green, IntPtr.Zero);
        }
        pBar.Value = newValue;
        SendMessage(pBar.Handle, 1040, (IntPtr)(int)Color.Green, IntPtr.Zero);     // run it out to the correct spot in default
        SendMessage(pBar.Handle, 1040, (IntPtr)(int)newColor, IntPtr.Zero);        // now turn it the correct color
    }

}

There's a function empty() ready for you in std::string:

std::string a;
if(a.empty())
{
    //do stuff. You will enter this block if the string is declared like this
}

or

std::string a;
if(!a.empty())
{
    //You will not enter this block now
}
a = "42";
if(!a.empty())
{
    //And now you will enter this block.
}

You could use CAST or CONVERT:

SELECT CAST(MyVarcharCol AS INT) FROM Table

SELECT CONVERT(INT, MyVarcharCol) FROM Table

Adding this to code to the required component's constructor worked for me.

this.router.routeReuseStrategy.shouldReuseRoute = function () {
  return false;
};

this.mySubscription = this.router.events.subscribe((event) => {
  if (event instanceof NavigationEnd) {
    // Trick the Router into believing it's last link wasn't previously loaded
    this.router.navigated = false;
  }
});

Make sure to unsubscribe from this mySubscription in ngOnDestroy().

ngOnDestroy() {
  if (this.mySubscription) {
    this.mySubscription.unsubscribe();
  }
}

Use YQL and you don't need to worry. It's a query language by Yahoo and you can get all the stock data including the name of the company for the ticker. It's a REST API and it returns the results via XML or JSON. I have a full tutorial and source code on my site take a look: http://www.jarloo.com/yahoo-stock-symbol-lookup/

I solved this problem using @Kjuly's answer and the specific line:

"The reason failed to build might be that, the project does not support the architecture of the device you connected."

With Xcode loaded it automatically set my iPad app to iPad Air

This caused the dependancy analysis error.

Changing the device type immediately solved the issue:

I don't know why this works but this is a very quick answer which saved me a lot of fiddling around in the background and instantly got the app working to test. I would never have thought that this could be a thing and something so simple would fix it but in this case it did.

Why don't you use a QSpinBox for this purpose ? You can set the up/down buttons invisible with the following line of codes:

// ...
QSpinBox* spinBox = new QSpinBox( this );
spinBox->setButtonSymbols( QAbstractSpinBox::NoButtons ); // After this it looks just like a QLineEdit.
//...

It depends, how big is the data set and what are your performance requirements?

If it's nothing gigantic use the most readable form, which for myself is any, because it's shorter and readable rather than an equation.

If you already know the filename, you can use the boto3 builtin download_fileobj

import boto3

from io import BytesIO

session = boto3.Session()
s3_client = session.client("s3")

f = BytesIO()
s3_client.download_fileobj(bucket_name, filename, f)
f.seek(0)
print(f.getvalue())

Combining Ege's dynamic solution with Vinay's idea, you get a nice robust solution:

Array.prototype.sortBy = function() {
    function _sortByAttr(attr) {
        var sortOrder = 1;
        if (attr[0] == "-") {
            sortOrder = -1;
            attr = attr.substr(1);
        }
        return function(a, b) {
            var result = (a[attr] < b[attr]) ? -1 : (a[attr] > b[attr]) ? 1 : 0;
            return result * sortOrder;
        }
    }
    function _getSortFunc() {
        if (arguments.length == 0) {
            throw "Zero length arguments not allowed for Array.sortBy()";
        }
        var args = arguments;
        return function(a, b) {
            for (var result = 0, i = 0; result == 0 && i < args.length; i++) {
                result = _sortByAttr(args[i])(a, b);
            }
            return result;
        }
    }
    return this.sort(_getSortFunc.apply(null, arguments));
}

Usage:

// Utility for printing objects
Array.prototype.print = function(title) {
    console.log("************************************************************************");
    console.log("**** "+title);
    console.log("************************************************************************");
    for (var i = 0; i < this.length; i++) {
        console.log("Name: "+this[i].FirstName, this[i].LastName, "Age: "+this[i].Age);
    }
}

// Setup sample data
var arrObj = [
    {FirstName: "Zach", LastName: "Emergency", Age: 35},
    {FirstName: "Nancy", LastName: "Nurse", Age: 27},
    {FirstName: "Ethel", LastName: "Emergency", Age: 42},
    {FirstName: "Nina", LastName: "Nurse", Age: 48},
    {FirstName: "Anthony", LastName: "Emergency", Age: 44},
    {FirstName: "Nina", LastName: "Nurse", Age: 32},
    {FirstName: "Ed", LastName: "Emergency", Age: 28},
    {FirstName: "Peter", LastName: "Physician", Age: 58},
    {FirstName: "Al", LastName: "Emergency", Age: 51},
    {FirstName: "Ruth", LastName: "Registration", Age: 62},
    {FirstName: "Ed", LastName: "Emergency", Age: 38},
    {FirstName: "Tammy", LastName: "Triage", Age: 29},
    {FirstName: "Alan", LastName: "Emergency", Age: 60},
    {FirstName: "Nina", LastName: "Nurse", Age: 54}
];

//Unit Tests
arrObj.sortBy("LastName").print("LastName Ascending");
arrObj.sortBy("-LastName").print("LastName Descending");
arrObj.sortBy("LastName", "FirstName", "-Age").print("LastName Ascending, FirstName Ascending, Age Descending");
arrObj.sortBy("-FirstName", "Age").print("FirstName Descending, Age Ascending");
arrObj.sortBy("-Age").print("Age Descending");

Note that const declarations are block-scoped.

const el: HTMLElement | null = document.getElementById('content');

if (el) {
  const definitelyAnElement: HTMLElement = el;
}

So the value of definitelyAnElement is not accessible outside of the {}.

1. In this user admin will not be allowed to login from another host though you have granted permission. the reason is that user admin is not identified by any password.

2. Grant the user admin with password using GRANT command once again

   mysql> GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' IDENTIFIED by 'password'
   

then check the GRANT LIST the out put will be like his

mysql> select user,host,password from mysql.user;

if the desired user for example user 'admin' is need to be allowed login then use once GRANT command and execute the command.

Now the user should be allowed to login.

Look for (that is, cd to)

that will usually be your C:\

Note that this does not require libcurl, Windows.h, or WinSock! No compilation of libraries, no project configuration, etc. I have this code working in Visual Studio 2017 c++ on Windows 10:

#pragma comment(lib, "urlmon.lib")

#include <urlmon.h>
#include <sstream>

using namespace std;

...

IStream* stream;
//Also works with https URL's - unsure about the extent of SSL support though.
HRESULT result = URLOpenBlockingStream(0, "http://google.com", &stream, 0, 0);
if (result != 0)
{
    return 1;
}
char buffer[100];
unsigned long bytesRead;
stringstream ss;
stream->Read(buffer, 100, &bytesRead);
while (bytesRead > 0U)
{
    ss.write(buffer, (long long)bytesRead);
    stream->Read(buffer, 100, &bytesRead);
}
stream.Release();
string resultString = ss.str();

I just figured out how to do this, as I wanted a simple API access script, libraries like libcurl were causing me all kinds of problems (even when I followed the directions...), and WinSock is just too low-level and complicated.

I'm not quite sure about all of the IStream reading code (particularly the while condition - feel free to correct/improve), but hey, it works, hassle free! (It makes sense to me that, since I used a blocking (synchronous) call, this is fine, that bytesRead would always be > 0U until the stream (ISequentialStream?) is finished being read, but who knows.)

for windows, if you want global config, then run

git config --global http.sslVerify false

To get the instance metadata use

wget -q -O - http://169.254.169.254/latest/meta-data/instance-id

in my case the right server name was the name of my computer. for example John-PC, or somth

Dave Delongs's Swift 2.0 answer was crashing for me (in iOS 9)

But this worked:

let fetchRequest = NSFetchRequest(entityName: "Car")
let deleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest)

    do {
        try managedObjectContext.executeRequest(deleteRequest)
        try managedObjectContext.save()
    }
    catch let error as NSError {
       // Handle error
    }

A solution is to create an Alias in your .gitconfig and call it easily:

[alias]
    tree = log --graph --decorate --pretty=oneline --abbrev-commit

And when you call it next time, you'll use:

git tree

To put it in your ~/.gitconfig without having to edit it, you can do:

git config --global alias.tree "log --graph --decorate --pretty=oneline --abbrev-commit"  

(If you don't use the --global it will put it in the .git/config of your current repo.)

I'm surprised no one mentioned the HTML entities   and   which produce horizontal white space equivalent to the characters n and m, respectively. If you want to accumulate horizontal white space quickly, those are more efficient than  .

1. no space
2.   
3.  
4.  

Along with <space> and  , these are the five entities HTML provides for horizontal white space.

Note that except for  , all entities allow breaking. Whatever text surrounds them will wrap to a new line if it would otherwise extend beyond the container boundary. With   it would wrap to a new line as a block even if the text before   could fit on the previous line.

Depending on your use case, that may be desired or undesired. For me, unless I'm dealing with things like names (John Doe), addresses or references (see eq. 5), breaking as a block is usually undesired.

I got it work by setting size to freeform

This worked perfectly

public class BackButton extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.chat_box);
        Toolbar chatbox_toolbar=(Toolbar)findViewById(R.id.chat_box_toolbar);
        chatbox_toolbar.setTitle("Demo Back Button");
        chatbox_toolbar.setTitleTextColor(getResources().getColor(R.color.white));
        setSupportActionBar(chatbox_toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        chatbox_toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                //Define Back Button Function
            }
        });
    }
}
