I tried to get an uwsgi:// working, but somehow the manual thought it was clear to me that I actually needed mod_proxy_uwsgi. It was not. Here is how you do it: How to compile mod_proxy_uwsgi or mod_uwsgi?

I recommend the jquery.post() method.

function useAdress () { 
var id = $("#choose-address-table").find(".nr:first").text();
alert (id);
$("#resultas").append(id); // Testing: append the contents of the td to a div
};

then on your button:

onclick="useAdress()"

Replace @RestController with @Controller.

In computer science terms, we talk about anonymous functions and named functions. I think the most important difference is that an anonymous function is not bound to an name, hence the name anonymous function. In JavaScript it is a first class object dynamically declared at runtime.

For more information on anonymous functions and lambda calculus, Wikipedia is a good start (http://en.wikipedia.org/wiki/Anonymous_function).

Try to put this in your CSS file.

td {
    text-align: center;
    vertical-align: middle;
}

There is a limit to the total size of all columns inlined into the index definition. That said though, I have never had to create index that wide. To me, the bigger advantage is the fact that you can cover more queries with one index that has included columns as they don't have to be defined in any particular order. Think about is as an index within the index. One example would be the StoreID (where StoreID is low selectivity meaning that each store is associated with a lot of customers) and then customer demographics data (LastName, FirstName, DOB): If you just inline those columns in this order (StoreID, LastName, FirstName, DOB), you can only efficiently search for customers for which you know StoreID and LastName.

On the other hand, defining the index on StoreID and including LastName, FirstName, DOB columns would let you in essence do two seeks- index predicate on StoreID and then seek predicate on any of the included columns. This would let you cover all possible search permutationsas as long as it starts with StoreID.

In my case got a working solution through Cross-document Messaging (XDM) and Executing Chrome extension onclick instead of page load.

You can try wx library. It's a cross platform UI library. Here you can find the printing tutorial: https://web.archive.org/web/20160619163747/http://wiki.wxpython.org/Printing

Since the class is added dynamically, you need to use event delegation to register the event handler

$(document).on('click', "a.tabclick", function() {
    var liId = $(this).parent("li").attr("id");
    alert(liId);        
});

Sadly no, there is no such thing as drop if exists, or CREATE IF NOT EXIST

You could write a plsql script to include the logic there.

http://download.oracle.com/docs/cd/B12037_01/server.101/b10759/statements_9003.htm

I'm not much into Oracle Syntax, but i think @Erich's script would be something like this.

declare 
cant integer
begin
select into cant count(*) from dba_tables where table_name='Table_name';
if count>0 then
BEGIN
    DROP TABLE tableName;
END IF;
END;

Actually, there is some possibility to send a table data from one PostgreSQL database to another. I use the procedural language plperlu (unsafe Perl procedural language) for it.

Description (all was done on a Linux server):

1. Create plperlu language in your database A

2. Then PostgreSQL can join some Perl modules through series of the following commands at the end of postgresql.conf for the database A:

   plperl.on_init='use DBI;'
   plperl.on_init='use DBD::Pg;'
   

3. You build a function in A like this:

   CREATE OR REPLACE FUNCTION send_data( VARCHAR )
   RETURNS character varying AS
   $BODY$
   my $command = $_[0] || die 'No SQL command!';
   my $connection_string =
   "dbi:Pg:dbname=your_dbase;host=192.168.1.2;port=5432;";
   $dbh = DBI->connect($connection_string,'user','pass',
   {AutoCommit=>0,RaiseError=>1,PrintError=>1,pg_enable_utf8=>1,}
   );
   my $sql = $dbh-> prepare( $command );
   eval { $sql-> execute() };
   my $error = $dbh-> state;
   $sql-> finish;
   if ( $error ) { $dbh-> rollback() } else {  $dbh-> commit() }
   $dbh-> disconnect();
   $BODY$
   LANGUAGE plperlu VOLATILE;
   

And then you can call the function inside database A:

SELECT send_data( 'INSERT INTO jm (jm) VALUES (''zzzzzz'')' );

And the value "zzzzzz" will be added into table "jm" in database B.

In XML

  android:layout_width="match_parent"
  android:layout_height="?attr/actionBarSize"
  app:layout_scrollFlags="scroll|enterAlways">

Kotlin: In fragment.kt -> onCreateView()

   override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
       inflater.inflate(R.menu.app_main_menu,menu)

   }

   override fun onOptionsItemSelected(item: MenuItem): Boolean {
        return when (item.itemId) {

    }

DARK_DIESEL's answer worked great for me; here's the code for anyone who wants the equivalent using glyphicons:

jQuery.validator.setDefaults({
    highlight: function (element, errorClass, validClass) {
        if (element.type === "radio") {
            this.findByName(element.name).addClass(errorClass).removeClass(validClass);
        } else {
            $(element).closest('.form-group').removeClass('has-success has-feedback').addClass('has-error has-feedback');
            $(element).closest('.form-group').find('span.glyphicon').remove();
            $(element).closest('.form-group').append('<span class="glyphicon glyphicon-remove form-control-feedback" aria-hidden="true"></span>');
        }
    },
    unhighlight: function (element, errorClass, validClass) {
        if (element.type === "radio") {
            this.findByName(element.name).removeClass(errorClass).addClass(validClass);
        } else {
            $(element).closest('.form-group').removeClass('has-error has-feedback').addClass('has-success has-feedback');
            $(element).closest('.form-group').find('span.glyphicon').remove();
            $(element).closest('.form-group').append('<span class="glyphicon glyphicon-ok form-control-feedback" aria-hidden="true"></span>');
        }
    }
});

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

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

Alternate solution: Maven

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

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

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

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

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

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

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

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

I've always wondered how costly it is to always assume that invoke is required...

private void OnCoolEvent(CoolObjectEventArgs e)
{
  BeginInvoke((o,e) => /*do work here*/,this, e);
}

The difference is subtle but important. The MOV instruction is a 'MOVe' effectively a copy of the address that the TABLE-ADDR label stands for. The LEA instruction is a 'Load Effective Address' which is an indirected instruction, which means that TABLE-ADDR points to a memory location at which the address to load is found.

Effectively using LEA is equivalent to using pointers in languages such as C, as such it is a powerful instruction.

When you want to watch on state level, it can be done this way:

let App = new Vue({
    //...
    store,
    watch: {
        '$store.state.myState': function (newVal) {
            console.log(newVal);
            store.dispatch('handleMyStateChange');
        }
    },
    //...
});

Just open it in 'a' mode:

a   Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file.

with open(filename, 'a') as f:
    f.write(...)

To see whether you're writing to a new file, check the stream position. If it's zero, either the file was empty or it is a new file.

with open('somefile.txt', 'a') as f:
    if f.tell() == 0:
        print('a new file or the file was empty')
        f.write('The header\n')
    else:
        print('file existed, appending')
    f.write('Some data\n')

If you're still using Python 2, to work around the bug, either add f.seek(0, os.SEEK_END) right after open or use io.open instead.

It really isn't easy or efficient, and I suggest you don't do it unless you really have to (and you probably don't have to unless this is homework since the applications of inplace merging are mostly theoretical). Can't you use quicksort instead? Quicksort will be faster anyway with a few simpler optimizations and its extra memory is O(log N).

Anyway, if you must do it then you must. Here's what I found: one and two. I'm not familiar with the inplace merge sort, but it seems like the basic idea is to use rotations to facilitate merging two arrays without using extra memory.

Note that this is slower even than the classic merge sort that's not inplace.

I use this all the time

You can customize the img class and the max-width property:

img{
    width: 100%;
    max-width: 800px;
}

max-width is important. Otherwise your image will scale too much for the desktop. There isn't any need to put in the height property, because by default it is auto mode.

You need some sort of Inter Process Communication. Use a pipe or a shared buffer.

One consideration is that FTP can use non-standard ports, which can make getting though firewalls difficult (especially if you're using SSL). HTTP is typically on a known port, so this is rarely a problem.

If you do decide to use FTP, make sure you read about Active and Passive FTP.

In terms of performance, at the end of the day they're both spewing files directly down TCP connections so should be about the same.

With regard to bootstrap, the correct answer is using spacing utilities as mentioned by loopasam in a previous comment. Following is an example of using padding for both left and right.

This error can get thrown if your data frame has sf geometry columns.

Try shFlags -- Advanced command-line flag library for Unix shell scripts.

http://code.google.com/p/shflags/

It is very good and very flexible.

FLAG TYPES: This is a list of the DEFINE_*'s that you can do. All flags take a name, default value, help-string, and optional 'short' name (one-letter name). Some flags have other arguments, which are described with the flag.

DEFINE_string: takes any input, and intreprets it as a string.

DEFINE_boolean: typically does not take any argument: say --myflag to set FLAGS_myflag to true, or --nomyflag to set FLAGS_myflag to false. Alternately, you can say --myflag=true or --myflag=t or --myflag=0 or --myflag=false or --myflag=f or --myflag=1 Passing an option has the same affect as passing the option once.

DEFINE_float: takes an input and intreprets it as a floating point number. As shell does not support floats per-se, the input is merely validated as being a valid floating point value.

DEFINE_integer: takes an input and intreprets it as an integer.

SPECIAL FLAGS: There are a few flags that have special meaning: --help (or -?) prints a list of all the flags in a human-readable fashion --flagfile=foo read flags from foo. (not implemented yet) -- as in getopt(), terminates flag-processing

EXAMPLE USAGE:

-- begin hello.sh --
 ! /bin/sh
. ./shflags
DEFINE_string name 'world' "somebody's name" n
FLAGS "$@" || exit $?
eval set -- "${FLAGS_ARGV}"
echo "Hello, ${FLAGS_name}."
-- end hello.sh --

$ ./hello.sh -n Kate
Hello, Kate.

Note: I took this text from shflags documentation

One way to do it will be to move all the php code above the HTML, copy the result to a variable and then add the result in the <input> tag.
Try this -

<?php
//Adding the php to the top.
if(isset($_POST['submit']))
{
    $value1=$_POST['value1'];
    $value2=$_POST['value2'];
    $sign=$_POST['sign'];
    ...
        //Adding to $result variable
    if($sign=='-') {
      $result = $value1-$value2;
    }
    //Rest of your code...
}
?>
<html>
<!--Rest of your tags...-->
Result:<br><input type"text" name="result" value = "<?php echo (isset($result))?$result:'';?>">

If you want to easily view the contents of objects while debugging, install a tool like Firebug and use console.log:

console.log(product);

If you want to view the properties of the object itself, don't alert the object, but its properties:

alert(product.ProductName);
alert(product.UnitPrice);
// etc... (or combine them)

As said, if you really want to boost your JavaScript debugging, use Firefox with the Firebug addon. You will wonder how you ever debugged your code before.

xrange() will not work for 3.x.

numpy.random.randint().tolist() is a great alternative for integers in a specified interval:

 #[In]:
import numpy as np
np.random.seed(123) #option for reproducibility
np.random.randint(low=0, high=100, size=10).tolist()

#[Out:]

[66, 92, 98, 17, 83, 57, 86, 97, 96, 47]

You also have np.random.uniform() for floats:

#[In]:
np.random.uniform(low=0, high=100, size=10).tolist()

#[Out]:
[69.64691855978616,
28.613933495037948,
22.68514535642031,

All you have to do is: $variable =NULL; // and pass it in the insert query. This will store the value as NULL in mysql db

You could specify the dtype directly when constructing the DataFrame:

>>> df = pd.DataFrame(index=range(0,4),columns=['A'], dtype='float')
>>> df.dtypes
A    float64
dtype: object

Specifying the dtype forces Pandas to try creating the DataFrame with that type, rather than trying to infer it.

If you want to find dependencies recursively (including dependencies of dependencies, dependencies of dependencies of dependencies and so on)…

You may use ldd command. ldd - print shared library dependencies

If you have something on your canvas and you want to draw something at the back of it - you can do it by changing the context.globalCompositeOperation setting to 'destination-over' - and then return it to 'source-over' when you're done.

date() itself is only for formatting, but it accepts a second parameter.

date("F j, Y", time() - 60 * 60 * 24);

To keep it simple I just subtract 24 hours from the unix timestamp.

A modern oop-approach is using DateTime

$date = new DateTime();
$date->sub(new DateInterval('P1D'));
echo $date->format('F j, Y') . "\n";

Or in your case (more readable/obvious)

$date = new DateTime();
$date->add(DateInterval::createFromDateString('yesterday'));
echo $date->format('F j, Y') . "\n";

(Because DateInterval is negative here, we must add() it here)

Copy the following line to your application manifest file and paste before the <application> tag.

<uses-permission android:name="android.permission.INTERNET"/>

Placing the permission below the <application/> tag will work, but will give you warning. So take care to place it before the <application/> tag declaration.

I wanted to know (idx, key, value) for a python OrderedDict today (mapping of SKUs to quantities in order of the way they should appear on a receipt). The answers here were all bummers.

In python 3, at least, this way works and and makes sense.

In [1]: from collections import OrderedDict
   ...: od = OrderedDict()
   ...: od['a']='spam'
   ...: od['b']='ham'
   ...: od['c']='eggs'
   ...: 
   ...: for i,(k,v) in enumerate(od.items()):
   ...:    print('%d,%s,%s'%(i,k,v))
   ...: 
0,a,spam
1,b,ham
2,c,eggs

C++98 doesn't provide a direct syntax for anything but zeroing (or for non-POD elements, value-initializing) the array. For that you just write C(): arr() {}.

I thing Roger Pate is wrong about the alleged limitations of C++0x aggregate initialization, but I'm too lazy to look it up or check it out, and it doesn't matter, does it? EDIT: Roger was talking about "C++03", I misread it as "C++0x". Sorry, Roger. ?

A C++98 workaround for your current code is to wrap the array in a struct and initialize it from a static constant of that type. The data has to reside somewhere anyway. Off the cuff it can look like this:

class C 
{
public:
    C() : arr( arrData ) {}

private:
     struct Arr{ int elem[3]; };
     Arr arr;
     static Arr const arrData;
};

C::Arr const C::arrData = {{1, 2, 3}};

You need to install the es2015 preset:

npm install babel-preset-es2015

and then configure babel-loader:

{
    test: /\.jsx?$/,
    loader: 'babel-loader',
    exclude: /node_modules/,
    query: {
        presets: ['es2015']
    }
}

1. uninstall node completely with the commands

curl -ksO https://gist.githubusercontent.com/nicerobot/2697848/raw/uninstall-node.sh
chmod +x ./uninstall-node.sh
./uninstall-node.sh
rm uninstall-node.sh

Or you could check out this website: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

if this doesn't work, you need to remove node via control panel or any other method. As long as it gets removed.

2. Install node via this website: https://nodejs.org/en/download/

If you use nvm, you can use:

nvm install node

You can already check if it works, then you don't need to take the following steps with: npm -v and then node -v

if you have nvm installed: command -v nvm

3. Uninstall npm using the following command:

sudo npm uninstall npm -g

Or, if that fails, get the npm source code, and do:

sudo make uninstall

If you have nvm installed, then use: nvm uninstall npm

4. Install npm using the following command: npm install -g grunt

My similar issue got fixed with below 2 approaches.

1) Through manually handling transactions:

Session session = sessionFactory.getCurrentSession();
Transaction tx = session.beginTransaction();
UserInfo user = (UserInfo) session.get(UserInfo.class, 1);
tx.commit();

2) Tell Spring to open and manage transactions for you in your web.xml filters and Ensure to use @Repository @Transactional:

<filter>
  <filter-name>hibernateFilter</filter-name>
  <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
  <init-param>
    <param-name>sessionFactory</param-name>
    <param-value>session.factory</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>hibernateFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

Do a reset of the configuration and set the root level to OFF

LogManager.getLogManager().reset();
Logger globalLogger = Logger.getLogger(java.util.logging.Logger.GLOBAL_LOGGER_NAME);
globalLogger.setLevel(java.util.logging.Level.OFF);

We use DBGhost to manage our SQL database. Then you put your scripts to build a new database in your version control, and it'll either build a new database, or upgrade any existing database to the schema in version control. That way you don't have to worry about creating change scripts (although you can still do that, if for example you want to change the data type of a column and need to convert data).

If you don't mind creating an extra date object, you could try:

var tempDate = new Date(parseInt(item.timestamp, 10));
var visitDate = new Date (tempDate.getUTCFullYear(), tempDate.getUTCMonth(), tempDate.getUTCDate());

I do something very similar to get a date of the current month without the time.

I tried all the suggestions above, but my actual issue was that my application was looking for the /font folder and its contents (.woff etc) in app/fonts, but my /fonts folder was on the same level as /app. I moved /fonts under /app, and it works fine now. I hope this helps someone else roaming the web for an answer.

Use an interval instead of an integer:

Walkthrough: Creating a SQL Server Compact 3.5 Database

To create a relationship between the tables created in the previous procedure

1. In Server Explorer/Database Explorer, expand Tables.
2. Right-click the Orders table and then click Table Properties.
3. Click Add Relations.
4. Type FK_Orders_Customers in the Relation Name box.
5. Select CustomerID in the Foreign Key Table Column list.
6. Click Add Columns.
7. Click Add Relation.
8. Click OK to complete the process and create the relationship in the database.
9. Click OK again to close the Table Properties dialog box.

I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:

 Task.Factory.StartNew(() =>
      {
        DoLongRunningWork();
        Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
              { txt.Text = "Complete"; }));
      });

I know this is late, but it does answer your original question.

If the XML is well formed then you can convert it to Document. By using the XPath you can get the XML Elements.

String xml = "<stackusers><name>Yash</name><age>30</age></stackusers>";

Form XML-String Create Document and find the elements using its XML-Path.

Document doc = getDocument(xml, true);

    public static Document getDocument(String xmlData, boolean isXMLData) throws Exception {
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        dbFactory.setNamespaceAware(true);
        dbFactory.setIgnoringComments(true);
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc;
        if (isXMLData) {
            InputSource ips = new org.xml.sax.InputSource(new StringReader(xmlData));
            doc = dBuilder.parse(ips);
        } else {
            doc = dBuilder.parse( new File(xmlData) );
        }
        return doc;
    }

Use org.apache.xpath.XPathAPI to get Node or NodeList.

System.out.println("XPathAPI:"+getNodeValue(doc, "/stackusers/age/text()"));

NodeList nodeList = getNodeList(doc, "/stackusers");
System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList));
System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList.item(0)));

    public static String getNodeValue(Document doc, String xpathExpression) throws Exception {
        Node node = org.apache.xpath.XPathAPI.selectSingleNode(doc, xpathExpression);
        String nodeValue = node.getNodeValue();
        return nodeValue;
    }
    public static NodeList getNodeList(Document doc, String xpathExpression) throws Exception {
        NodeList result = org.apache.xpath.XPathAPI.selectNodeList(doc, xpathExpression);
        return result;
    }

Using javax.xml.xpath.XPathFactory

System.out.println("javax.xml.xpath.XPathFactory:"+getXPathFactoryValue(doc, "/stackusers/age"));

    static XPath xpath = javax.xml.xpath.XPathFactory.newInstance().newXPath();
    public static String getXPathFactoryValue(Document doc, String xpathExpression) throws XPathExpressionException, TransformerException, IOException {
        Node node = (Node) xpath.evaluate(xpathExpression, doc, XPathConstants.NODE);
        String nodeStr = getXmlContentAsString(node);
        return nodeStr;
    }

Using Document Element.

System.out.println("DocumentElementText:"+getDocumentElementText(doc, "age"));

    public static String getDocumentElementText(Document doc, String elementName) {
        return doc.getElementsByTagName(elementName).item(0).getTextContent();
    }

Get value in between two strings.

String nodeVlaue = org.apache.commons.lang.StringUtils.substringBetween(xml, "<age>", "</age>");
System.out.println("StringUtils.substringBetween():"+nodeVlaue);

Full Example:

public static void main(String[] args) throws Exception {
    String xml = "<stackusers><name>Yash</name><age>30</age></stackusers>";
    Document doc = getDocument(xml, true);
    
    String nodeVlaue = org.apache.commons.lang.StringUtils.substringBetween(xml, "<age>", "</age>");
    System.out.println("StringUtils.substringBetween():"+nodeVlaue);
    
    System.out.println("DocumentElementText:"+getDocumentElementText(doc, "age"));
    System.out.println("javax.xml.xpath.XPathFactory:"+getXPathFactoryValue(doc, "/stackusers/age"));
    
    System.out.println("XPathAPI:"+getNodeValue(doc, "/stackusers/age/text()"));
    NodeList nodeList = getNodeList(doc, "/stackusers");
    System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList));
    System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList.item(0)));
}
public static String getXmlContentAsString(Node node) throws TransformerException, IOException {
    StringBuilder stringBuilder = new StringBuilder();
    NodeList childNodes = node.getChildNodes();
    int length = childNodes.getLength();
    for (int i = 0; i < length; i++) {
        stringBuilder.append( toString(childNodes.item(i), true) );
    }
    return stringBuilder.toString();
}

OutPut:

StringUtils.substringBetween():30
DocumentElementText:30
javax.xml.xpath.XPathFactory:30
XPathAPI:30
XPathAPI NodeList:<stackusers>
   <name>Yash</name>
   <age>30</age>
</stackusers>
XPathAPI NodeList:<name>Yash</name><age>30</age>

I've made this mistake in the past & I took forever to figure it out.

Why can't we create Object of Abstract Class ? When we create a pure virtual function in Abstract class, we reserve a slot for a function in the VTABLE(studied in last topic), but doesn't put any address in that slot. Hence the VTABLE will be incomplete. As the VTABLE for Abstract class is incomplete, hence the compiler will not let the creation of object for such class and will display an errror message whenever you try to do so.

Pure Virtual definitions

Pure Virtual functions can be given a small definition in the Abstract class, which you want all the derived classes to have. Still you cannot create object of Abstract class. Also, the Pure Virtual function must be defined outside the class definition. If you will define it inside the class definition, complier will give an error. Inline pure virtual definition is Illegal.

Following should work

$d = strtotime("+1 months",strtotime("2015-05-25"));
echo   date("Y-m-d",$d); // This will print **2015-06-25** 

Well... you are about 3/4 of the way there... you already have your JSON as text.

The problem is that you appear to be handling this string as if it was already a JavaScript object with properties relating to the fields that were transmitted.

It isn't... its just a string.

Queries like "content = data[x].Id;" are bound to fail because JavaScript is not finding these properties attached to the string that it is looking at... again, its JUST a string.

You should be able to simply parse the data as JSON through... yup... the parse method of the JSON object.

myResult = JSON.parse(request.responseText);

Now myResult is a javascript object containing the properties that were transmitted through AJAX.

That should allow you to handle it the way you appear to be trying to.

Looks like JSON.parse was added when ECMA5 was added, so anything fairly modern should be able to handle this natively... if you have to handle fossils, you could also try external libraries to handle this, such as jQuery or JSON2.

For the record, this was already answered by Andy E for someone else HERE.

edit - Saw the request for 'official or credible sources', and probably one of the coders that I find the most credible would be John Resig ~ ECMA5 JSON ~ i would have linked to the actual ECMA5 spec regarding native JSON support, but I would rather refer someone to a master like Resig than a dry specification.

Simple way is:

Math.Ceiling(decimal.Parse(yourNumber + ""));

There is no built-in extension method to do this. Although defining one is fairly straight forward. At the bottom of the post is a method I defined called Iterate. It can be used like so

collection.Iterate(c => { c.PropertyToSet = value;} );

Iterate Source

public static void Iterate<T>(this IEnumerable<T> enumerable, Action<T> callback)
{
    if (enumerable == null)
    {
        throw new ArgumentNullException("enumerable");
    }

    IterateHelper(enumerable, (x, i) => callback(x));
}

public static void Iterate<T>(this IEnumerable<T> enumerable, Action<T,int> callback)
{
    if (enumerable == null)
    {
        throw new ArgumentNullException("enumerable");
    }

    IterateHelper(enumerable, callback);
}

private static void IterateHelper<T>(this IEnumerable<T> enumerable, Action<T,int> callback)
{
    int count = 0;
    foreach (var cur in enumerable)
    {
        callback(cur, count);
        count++;
    }
}

Try Facetype.js, you convert your .TTF font into a Javascript file. Full SEO compatible, supports FF, IE6 and Safari and degrades gracefully on other browsers.

use a negative character class:

[^,;]+

$this-> is used to refer to a specific instance of a class's variables (member variables) or methods.

Example: 
$derek = new Person();

$derek is now a specific instance of Person. Every Person has a first_name and a last_name, but $derek has a specific first_name and last_name (Derek Martin). Inside the $derek instance, we can refer to those as $this->first_name and $this->last_name

ClassName:: is used to refer to that type of class, and its static variables, static methods. If it helps, you can mentally replace the word "static" with "shared". Because they are shared, they cannot refer to $this, which refers to a specific instance (not shared). Static Variables (i.e. static $db_connection) can be shared among all instances of a type of object. For example, all database objects share a single connection (static $connection).

Static Variables Example: Pretend we have a database class with a single member variable: static $num_connections; Now, put this in the constructor:

function __construct()
{
    if(!isset $num_connections || $num_connections==null)
    {
        $num_connections=0;
    }
    else
    {
        $num_connections++;
    }
}

Just as objects have constructors, they also have destructors, which are executed when the object dies or is unset:

function __destruct()
{
    $num_connections--;
}

Every time we create a new instance, it will increase our connection counter by one. Every time we destroy or stop using an instance, it will decrease the connection counter by one. In this way, we can monitor the number of instances of the database object we have in use with:

echo DB::num_connections;

Because $num_connections is static (shared), it will reflect the total number of active database objects. You may have seen this technique used to share database connections among all instances of a database class. This is done because creating the database connection takes a long time, so it's best to create just one, and share it (this is called a Singleton Pattern).

Static Methods (i.e. public static View::format_phone_number($digits)) can be used WITHOUT first instantiating one of those objects (i.e. They do not internally refer to $this).

Static Method Example:

public static function prettyName($first_name, $last_name)
{
    echo ucfirst($first_name).' '.ucfirst($last_name);
}

echo Person::prettyName($derek->first_name, $derek->last_name);

As you can see, public static function prettyName knows nothing about the object. It's just working with the parameters you pass in, like a normal function that's not part of an object. Why bother, then, if we could just have it not as part of the object?

1. First, attaching functions to objects helps you keep things organized, so you know where to find them.
2. Second, it prevents naming conflicts. In a big project, you're likely to have two developers create getName() functions. If one creates a ClassName1::getName(), and the other creates ClassName2::getName(), it's no problem at all. No conflict. Yay static methods!

SELF:: If you are coding outside the object that has the static method you want to refer to, you must call it using the object's name View::format_phone_number($phone_number); If you are coding inside the object that has the static method you want to refer to, you can either use the object's name View::format_phone_number($pn), OR you can use the self::format_phone_number($pn) shortcut

The same goes for static variables: Example: View::templates_path versus self::templates_path

Inside the DB class, if we were referring to a static method of some other object, we would use the object's name: Example: Session::getUsersOnline();

But if the DB class wanted to refer to its own static variable, it would just say self: Example: self::connection;

Hope that helps clear things up :)

Java programming language enums are far more powerful than their counterparts in other languages, which are little more than glorified integers. The new enum declaration defines a full-fledged class (dubbed an enum type). In addition to solving all the problems(Not typesafe, No namespace, Brittleness and Printed values are uninformative) that exists with following int Enum pattern which was used prior to java 5.0 :

public static final int SEASON_WINTER = 0;

it also allows you to add arbitrary methods and fields to an enum type, to implement arbitrary interfaces, and more. Enum types provide high-quality implementations of all the Object methods. They are Comparable and Serializable, and the serial form is designed to withstand arbitrary changes in the enum type. You can also use Enum in switch case.

Read the full article on Java Enums http://docs.oracle.com/javase/1.5.0/docs/guide/language/enums.html for more details.

You can make master point at 1258f0d0aae this way:

git checkout master
git reset --hard 1258f0d0aae

But you have to be careful about doing this. It may well rewrite the history of that branch. That would create problems if you have published it and other people are working on the branch.

Also, the git reset --hard command will throw away any uncommitted changes (i.e. those just in your working tree or the index).

You can also force an update to a branch with:

git branch -f master 1258f0d0aae

... but git won't let you do that if you're on master at the time.

If you are using Spring

return new ResponseEntity<String>("your response", HttpStatus.ACCEPTED);

Laravel 5 promotes the use of namespaces for things like Models and Controllers. Your Model is under the App namespace, so your code needs to call it like this:

Route::get('/posts', function(){

        $results = \App\Post::all();
        return $results;
});

As mentioned in the comments you can also use or import a namespace in to a file so you don't need to quote the full path, like this:

use App\Post;

Route::get('/posts', function(){

        $results = Post::all();
        return $results;
});

While I'm doing a short primer on namespaces I might as well mention the ability to alias a class as well. Doing this means you can essentially rename your class just in the scope of one file, like this:

use App\Post as PostModel;

Route::get('/posts', function(){

        $results = PostModel::all();
        return $results;
});

More info on importing and aliasing namespaces here: http://php.net/manual/en/language.namespaces.importing.php

What are disadvantages of the following solution? Seems to be faster and shorter.

var options = {
    set0: ['Option 1','Option 2'],
    set1: ['First Option','Second Option','Third Option']
};

var list = "<li>" + options.set0.join("</li><li>") + "</li>";
document.getElementById("list").innerHTML = list;

A CRLF is two characters, of course, the CR and the LF. However, `n consists of both. For example:

PS C:\> $x = "Hello
>> World"

PS C:\> $x
Hello
World
PS C:\> $x.contains("`n")
True
PS C:\> $x.contains("`r")
False
PS C:\> $x.replace("o`nW","o There`nThe W")
Hello There
The World
PS C:\>

I think you're running into problems with the `r. I was able to remove the `r from your example, use only `n, and it worked. Of course, I don't know exactly how you generated the original string so I don't know what's in there.

Supports globbing, too:

% git log --all -- '**/my_file.png'

The single quotes are necessary (at least if using the Bash shell) so the shell passes the glob pattern to git unchanged, instead of expanding it (just like with Unix find).

You could also use the coalesce function. I tested this in PostgreSQL, but it should also work for MySQL or MS SQL server.

INNER JOIN x ON coalesce(x.qid, -1) = coalesce(y.qid, -1)

This will replace NULL with -1 before evaluating it. Hence there must be no -1 in qid.

In Ruby and other languages that support POSIX character classes in bracket expressions, you can do simply:

/\A[[:alpha:]]+\z/i

That will match alpha-chars in all Unicode alphabet languages. Easy peasy.

This is a feature, not a bug.

See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.

As of today, your best bet is to use:

img = cv2.imread(image_path)   # reads an image in the BGR format
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)   # BGR -> RGB

You'll see img will be a numpy array of type:

<class 'numpy.ndarray'>

Also you can download and execute the install.bat file in 'ODAC112030Xcopy.zip' from 64-bit Oracle Data Access Components (ODAC) Downloads. This resolved my problem.

Thanks @Gabriel-Perez and @Groo, great idea! In case others want it, here's a version in VB tested in Visual Studio 2012. In my case I wanted the numbers to appear top right aligned in the Row Header.

Private Sub MyDGV_RowPostPaint(sender As Object, _
    e As DataGridViewRowPostPaintEventArgs) Handles MyDataGridView.RowPostPaint

    ' Automatically maintains a Row Header Index Number 
    '   like the Excel row number, independent of sort order

    Dim grid As DataGridView = CType(sender, DataGridView)
    Dim rowIdx As String = (e.RowIndex + 1).ToString()
    Dim rowFont As New System.Drawing.Font("Tahoma", 8.0!, _
        System.Drawing.FontStyle.Bold, _
        System.Drawing.GraphicsUnit.Point, CType(0, Byte))

    Dim centerFormat = New StringFormat()
    centerFormat.Alignment = StringAlignment.Far
    centerFormat.LineAlignment = StringAlignment.Near

    Dim headerBounds As Rectangle = New Rectangle(_
        e.RowBounds.Left, e.RowBounds.Top, _
        grid.RowHeadersWidth, e.RowBounds.Height)
    e.Graphics.DrawString(rowIdx, rowFont, SystemBrushes.ControlText, _
        headerBounds, centerFormat)
End Sub

You can also get the default font, rowFont = grid.RowHeadersDefaultCellStyle.Font, but it might not look as good. The screenshot below is using the Tahoma font.

Edit: As of iOS 3.2, this functionality is built in. If you need to support pre-3.2, you can still use this solution.

I created a simple module that extends UILabel and handles loading .ttf files. I released it opensource under the Apache license and put it on github Here.

The important files are FontLabel.h and FontLabel.m.

It uses some of the code from Genericrich's answer.

Browse the source Here.

OR

• Copy your font file into resources

• Add a key to your Info.plist file called UIAppFonts. ("Fonts provided by application)

• Make this key an array

• For each font you have, enter the full name of your font file (including the extension) as items to the UIAppFonts array

• Save Info.plist

• Now in your application you can simply call [UIFont fontWithName:@"CustomFontName" size:15] to get the custom font to use with your UILabels and UITextViews, etc…

For More Information

Simply print the model after defining an object for the model class

class RNN(nn.Module):
    def __init__(self, input_dim, embedding_dim, hidden_dim, output_dim):
        super().__init__()

        self.embedding = nn.Embedding(input_dim, embedding_dim)
        self.rnn = nn.RNN(embedding_dim, hidden_dim)
        self.fc = nn.Linear(hidden_dim, output_dim)
    def forward():
        ...

model = RNN(input_dim, embedding_dim, hidden_dim, output_dim)
print(model)

You could use the tr instead:

       $p =~ tr/fo//d;

will delete every f and every o from $p. In your case it should be:

       $p =~ tr/\$#@~!&*()[];.,:?^ `\\\///d

See Perl's tr documentation.

tr/SEARCHLIST/REPLACEMENTLIST/cdsr

Transliterates all occurrences of the characters found (or not found if the /c modifier is specified) in the search list with the positionally corresponding character in the replacement list, possibly deleting some, depending on the modifiers specified.

[…]

If the /d modifier is specified, any characters specified by SEARCHLIST not found in REPLACEMENTLIST are deleted.

The FFT output coefficients (for complex input of size N) are from 0 to N - 1 grouped as [LOW,MID,HI,HI,MID,LOW] frequency.

I would consider that the element at k has the same frequency as the element at N-k since for real data, FFT[N-k] = complex conjugate of FFT[k].

The order of scanning from LOW to HIGH frequency is

0,

 1,
 N-1,

 2,
 N-2

 ...

 [N/2] - 1,
 N - ([N/2] - 1) = [N/2]+1,

 [N/2]

There are [N/2]+1 groups of frequency from index i = 0 to [N/2], each having the frequency = i * SamplingFrequency / N

So the frequency at bin FFT[k] is:

if k <= [N/2] then k * SamplingFrequency / N
if k >= [N/2] then (N-k) * SamplingFrequency / N

There are additional base64 specs. (See the table here for specifics ). But essentially you need 65 chars to encode: 26 lowercase + 26 uppercase + 10 digits = 62.

You need two more ['+', '/'] and a padding char '='. But none of them are url friendly, so just use different chars for them and you're set. The standard ones from the chart above are ['-', '_'], but you could use other chars as long as you decoded them the same, and didn't need to share with others.

I'd recommend just writing your own helpers. Like these from the comments on the php manual page for base64_encode:

function base64_url_encode($input) {
 return strtr(base64_encode($input), '+/=', '._-');
}

function base64_url_decode($input) {
 return base64_decode(strtr($input, '._-', '+/='));
}

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

.wrapper {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  align-items: stretch;_x000D_
  width: 100%;_x000D_
  height: 5em;_x000D_
  background: #ccc;_x000D_
}_x000D_
.wrapper > .left_x000D_
{_x000D_
  background: #fcc;_x000D_
}_x000D_
.wrapper > .right_x000D_
{_x000D_
  background: #ccf;_x000D_
  flex: 1; _x000D_
}

<div class="wrapper">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_
</div>

• Specify flex: 1; for both children if you want them to fill equal amounts of the horizontal space:

.wrapper {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  align-items: stretch;_x000D_
  width: 100%;_x000D_
  height: 5em;_x000D_
  background: #ccc;_x000D_
}_x000D_
.wrapper > div _x000D_
{_x000D_
  flex: 1; _x000D_
}_x000D_
.wrapper > .left_x000D_
{_x000D_
  background: #fcc;_x000D_
}_x000D_
.wrapper > .right_x000D_
{_x000D_
  background: #ccf;_x000D_
}

<div class="wrapper">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_
</div>

This will do it for you:

var yourSelect = document.getElementById( "your-select-id" );
alert( yourSelect.options[ yourSelect.selectedIndex ].value )

I have a very simple solution to just print json from csv on console using csvtojson module.

// require csvtojson
var csv = require("csvtojson");

const csvFilePath='customer-data.csv' //file path of csv
csv()
.fromFile(csvFilePath)``
.then((jsonObj)=>{
    console.log(jsonObj);
})

If you are using jQuery 1.7:

alert($(this).prop("class"));

or:

alert($(event.target).prop("class"));

import the module

import pandas as pd
import oursql

connect

conn=oursql.connect(host="localhost",user="me",passwd="mypassword",db="classicmodels")
sql="Select customerName, city,country from customers order by customerName,country,city"
df_mysql = pd.read_sql(sql,conn)
print df_mysql

That works just fine and using pandas.io.sql frame_works (with the deprecation warning). Database used is the sample database from mysql tutorial.

The resize event works on modern browsers by attaching the event on window, and then reading values of thebody, or other element with for example (.getBoundingClientRect()).

In some earlier browsers it was possible to register resize event handlers on any HTML element. It is still possible to set onresize attributes or use addEventListener() to set a handler on any element. However, resize events are only fired on the window object (i.e. returned by document.defaultView). Only handlers registered on the window object will receive resize events.

window.addEventListener("resize", getSizes, false)_x000D_
        _x000D_
function getSizes(){_x000D_
  let body = document.body_x000D_
  console.log(body.clientWidth +"px x "+ body.clientHeight + "px")_x000D_
}

An other alternative: the ResizeObserver API

Depending your layout, you can watch for resizing on a particular element.

This works well on «responsive» layouts, because the container box get resized when zooming.

function watchBoxchange(e){_x000D_
 // console.log(e[0].contentBoxSize.inlineSize+" "+e[0].contentBoxSize.blockSize)_x000D_
 info.textContent = e[0].contentBoxSize.inlineSize+" * "+e[0].contentBoxSize.blockSize + "px"_x000D_
}_x000D_
_x000D_
new ResizeObserver(watchBoxchange).observe(fluid)

#fluid {_x000D_
  width: 200px;_x000D_
  height:100px;_x000D_
  overflow: auto;_x000D_
  resize: both;_x000D_
  border: 3px black solid;_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  font-size: 8vh_x000D_
}

<div id="fluid">_x000D_
   <info id="info"></info> _x000D_
</div>

Be careful to not overload javascript tasks from user gestures events. Use requestAnimationFrame whenever you needs redraws.

Check out the "--only-keep-debug" option of the strip command.

From the link:

The intention is that this option will be used in conjunction with --add-gnu-debuglink to create a two part executable. One a stripped binary which will occupy less space in RAM and in a distribution and the second a debugging information file which is only needed if debugging abilities are required.

I have created an answer for this post that might help: https://stackoverflow.com/a/63816822/2399164

Summary:

I am a little late to the game but I believe I found a simple solution to this problem...

1. Create a "NuGet.Config" file in the same directory as your .sln

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="{{CUSTOM NAME}}" value="{{CUSTOM SOURCE}}" />
  </packageSources>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
</configuration>

2. That is it! Create your "Dockerfile" here as well

3. Run docker build with your Dockerfile and all will get resolved

You have System.out.println("Scanning...") in a catch block. Do you want to put that in try?

Use the modulo arithmetic operation found here in the PHP manual.

e.g.

$x = 3;

for($i=0; $i<10; $i++)
{
    if($i % $x == 0)
    {
        // display image
    }
}

For a more detailed understanding of modulus calculations, click here.

#include<string.h>
#include<stdio.h>
int main()
{
    char input[16] = "abc,d";
    char *p;
    p = strtok(input, ",");

    if(p)
    {
    printf("%s\n", p);
    }
    p = strtok(NULL, ",");

    if(p)
           printf("%s\n", p);
    return 0;
}

you can look this program .First you should use the strtok(input, ",").input is the string you want to spilt.Then you use the strtok(NULL, ","). If the return value is true ,you can print the other group.

I would use ternary operators to categorize your switch conditions.

So...

switch( number > 9 ? "High" :
        number > 5 ? "Mid" :
        number > 1 ? "Low" : "Floor")
        {
              case "High":
                    do the thing;
                    break;
               case "Mid":
                    do the other thing;
                    break;
               case "Low":
                    do something else;
                    break;
               case "Floor":
                    do whatever;
                    break;
         }

Check the android documentation. It's in fact not much different than standard java io file handling so you could also check that documentation.

An example from the android documentation:

String FILENAME = "hello_file";
String string = "hello world!";

FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();

I have created my personal batch file for this, mine is a little different but feel free to modify as you see fit. I created this a little while ago because I was bored and wanted to make a simple way for people to be able to input ending, starting, stopping, or setting to auto. This BAT file simply requests that you input the service name and it will do the rest for you. I didn't realize that he was looking for something that stated any error, I must have misread that part. Though typically this can be done by inputting >> output.txt on the end of the line.

The %var% is just a way for the user to be able to input their own service into this, instead of having to go modify the bat file every time that you want to start/stop a different service.

If I am wrong, anyone can feel free to correct me on this.

@echo off
set /p c= Would you like to start a service [Y/N]?
  if /I "%c%" EQU "Y" goto :1
  if /I "%c%" EQU "N" goto :2
    :1  
    set /p var= Service name: 
:2 
set /p c= Would you like to stop a service [Y/N]?
  if /I "%c%" EQU "Y" goto :3
  if /I "%c%" EQU "N" goto :4
    :3  
    set /p var1= Service name:
:4
set /p c= Would you like to disable a service [Y/N]?
  if /I "%c%" EQU "Y" goto :5
  if /I "%c%" EQU "N" goto :6
    :5  
    set /p var2= Service name:
:6 
set /p c= Would you like to set a service to auto [Y/N]?
  if /I "%c%" EQU "Y" goto :7
  if /I "%c%" EQU "N" goto :10
    :7  
    set /p var3= Service name:
:10
sc start %var%
sc stop %var1%
sc config %var2% start=disabled
sc config %var3% start=auto

Assuming that the order is the same in both objects, just stringify them both and compare!

JSON.stringify(obj1) == JSON.stringify(obj2);

Use shutil.which() from Python's wonderful standard library. Batteries included!

Since you know the chars are lower case, you can subtract the according ASCII value to make them uppercase:

char a = 'a';
a -= 32;
System.out.println("a is " + a); //a is A

Here is an ASCII table for reference

In .NET Core 2.2, add this line to your Program.cs:

using ...
using System.Runtime.CompilerServices;

[assembly: InternalsVisibleTo("MyAssembly.Unit.Tests")]

namespace
{
...

The standard error (SE) is just the standard deviation of the sampling distribution. The variance of the sampling distribution is the variance of the data divided by N and the SE is the square root of that. Going from that understanding one can see that it is more efficient to use variance in the SE calculation. The sd function in R already does one square root (code for sd is in R and revealed by just typing "sd"). Therefore, the following is most efficient.

se <- function(x) sqrt(var(x)/length(x))

in order to make the function only a bit more complex and handle all of the options that you could pass to var, you could make this modification.

se <- function(x, ...) sqrt(var(x, ...)/length(x))

Using this syntax one can take advantage of things like how var deals with missing values. Anything that can be passed to var as a named argument can be used in this se call.

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

For simplicity sake here is what I did.

cd /etc/apt
mkdir test
cp sources.lst test
cd test
sed -i -- 's/us.archive/old-releases/g' *
sed -i -- 's/security/old-releases/g' *
cp sources.lst ../
sudo apt-get update

SQL Developer can show the blob as an image (at least it works for jpegs). In the Data view, double click on the BLOB field to get the "pencil" icon. Click on the pencil to get a dialog that will allow you to select a "View As Image" checkbox.

A simple way to do it using python :

Python
import numpy as np
import imageio

image = imageio.imread(r'[image-path]', as_gray=True)

# getting the threshold value
thresholdValue = np.mean(image)

# getting the dimensions of the image
xDim, yDim = image.shape

# turn the image into a black and white image
for i in range(xDim):
    for j in range(yDim):
        if (image[i][j] > thresholdValue):
            image[i][j] = 255
        else:
            image[i][j] = 0

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id is a newly generated ObjectId.

You can read more about the Types object at Mongoose#Types documentation.

The correct syntax is:

import sampleModule = require('modulename');

or

import * as sampleModule from 'modulename';

Then compile your TypeScript with --module commonjs.

If the package doesn't come with an index.d.ts file and its package.json doesn't have a "typings" property, tsc will bark that it doesn't know what 'modulename' refers to. For this purpose you need to find a .d.ts file for it on http://definitelytyped.org/, or write one yourself.

If you are writing code for Node.js you will also want the node.d.ts file from http://definitelytyped.org/.

Yes VBA is the way to go.

But, if you don't need to have a cell with formula that auto-counts/updates the number of cells with a particular colour, an alternative is simply to use the 'Find and Replace' function and format the cell to have the appropriate colour fill.

Hitting 'Find All' will give you the total number of cells found at the bottom left of the dialogue box.

This becomes especially useful if your search range is massive. The VBA script will be very slow but the 'Find and Replace' function will still be very quick.

a = []
a.append(["Nick", 30, "Doctor"])
a.append(["John",  8, "Student"])
a.append(["Paul",  8,"Car Dealer"])
a.append(["Mark", 66, "Retired"])
print a

[['Nick', 30, 'Doctor'], ['John', 8, 'Student'], ['Paul', 8, 'Car Dealer'], ['Mark', 66, 'Retired']]

def _cmp(a,b):     

    if a[1]<b[1]:
        return -1
    elif a[1]>b[1]:
        return 1
    else:
        return 0

You can rename a file using git's mv command:

$ git mv file_from file_to

Example:

$ git mv helo.txt hello.txt

$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    helo.txt -> hello.txt
#

$ git commit -m "renamed helo.txt to hello.txt"
[master 14c8c4f] renamed helo.txt to hello.txt
 1 files changed, 0 insertions(+), 0 deletions(-)
 rename helo.txt => hello.txt (100%)

CS researchers, as those from Math, are fond of creating "new" terms. The answers above are all nice but apparently, there is no such a great need to distinguish tokens and lexemes IMHO. They are like two ways to represent the same thing. A lexeme is concrete -- here a set of char; a token, on the other hand, is abstract -- usually referring to the type of a lexeme together with its semantic value if that makes sense. Just my two cents.

In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:

1. validating the data POSTed

2. make sure your API is sending the Content-Type header to tell the client to expect a JSON response:

   header('Content-Type: application/json');
   echo json_encode($response);
   

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.

If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController with an add() action/method.

There are a few starting point projects for RESTful APIs on GitHub that are worth a look.

There should be three pages here:

1. Initial login page with a form that asks for your username, but not your password.
2. You didn't mention this one, but I'd check whether the client computer is recognized, and if not, then challenge the user with either a CAPTCHA or else a security question. Otherwise the phishing site can simply use the tendered username to query the real site for the security image, which defeats the purpose of having a security image. (A security question is probably better here since with a CAPTCHA the attacker could have humans sitting there answering the CAPTCHAs to get at the security images. Depends how paranoid you want to be.)
3. A page after that that displays the security image and asks for the password.

I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.

I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.

You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST submission on step 1 (and 2 if applicable).

I solved my problem using some css into the web page.

<style media="print">
   @page {
      size: auto;
      margin: 0;
  }
</style>

If NEW_TABLE already exists then ...

insert into new_table 
select * from old_table
/

If you want to create NEW_TABLE based on the records in OLD_TABLE ...

create table new_table as 
select * from old_table
/

If the purpose is to create a new but empty table then use a WHERE clause with a condition which can never be true:

create table new_table as 
select * from old_table
where 1 = 2
/

Remember that CREATE TABLE ... AS SELECT creates only a table with the same projection as the source table. The new table does not have any constraints, triggers or indexes which the original table might have. Those still have to be added manually (if they are required).

As distributionUrl is still pointing to older version, upgrade wrapper using:

gradle wrapper --gradle-version 5.1.1

Note: Use gradle and not gradlew

It seems the problem is that / is not floor operation.

int mod(int m, float n)
{  
  return m - floor(m/n)*n;
}

Keep it nice, short, simple, and maintainable! :]

This code is simply a short functional example that could require additional feature functionality for full support on any (or given) platform.

You cannot include style directives in GFM.

The most complete documentation/example is "Markdown Cheatsheet", and it illustrates that this element <style> is missing.

If you manage to include your text in one of the GFM elements, then you can play with a github.css stylesheet in order to colors that way, meaning to color using inline CSS style directives, referring to said css stylesheet.

You can't do this yourself since Java doesn't permit operator overloading.

With one exception, however. + and += are overloaded for String objects.

If you'd like to turn this on by default for ALL ObjectMapper instances in a process, here's a little hack that will set the default value of INDENT_OUTPUT to true:

val indentOutput = SerializationFeature.INDENT_OUTPUT
val defaultStateField = indentOutput.getClass.getDeclaredField("_defaultState")
defaultStateField.setAccessible(true)
defaultStateField.set(indentOutput, true)

I got this way to close fading my Alert after 3 seconds. Hope it will be useful.

    setTimeout(function(){
    $('.alert').fadeTo("slow", 0.1, function(){
        $('.alert').alert('close')
    });     
    }, 3000)

Or, if you know the width of the two "side" images and don't want to deal with floats:

<div class="container">
    <div class="left-panel"><img src="myleftimage" /></div>
    <div class="center-panel">Content goes here...</div>
    <div class="right-panel"><img src="myrightimage" /></div>
</div>

CSS:

.container {
    position:relative;
    padding-left:50px;
    padding-right:50px;
}

.container .left-panel {
    width: 50px;
    position:absolute;
    left:0px;
    top:0px;
}

.container .right-panel {
    width: 50px;
    position:absolute;
    right:0px;
    top:0px;
}

.container .center-panel {
    background: url('mymiddleimage');
}

Notes:

Position:relative on the parent div is used to make absolutely positioned children position themselves relative to that node.

Why not just use separate console.log() for each var, and separate with a comma rather than converting them all to strings? That would give you separate lines, AND give you the true value of each variable rather than the string representation of each (assuming they may not all be strings).

console.log('roleName',roleName);
console.log('role_ID',role_ID);
console.log('modal_ID',modal_ID);
console.log('related',related);

And I think it would be easier to read/maintain.

In Visual C++ you can also use this notation inside constructor: this->Classname::Classname(parameters of another constructor). See an example below:

class Vertex
{
 private:
  int x, y;
 public:
  Vertex(int xCoo, int yCoo): x(xCoo), y(yCoo) {}
  Vertex()
  {
   this->Vertex::Vertex(-1, -1);
  }
};

I don't know whether it works somewhere else, I only tested it in Visual C++ 2003 and 2008. You may also call several constructors this way, I suppose, just like in Java and C#.

P.S.: Frankly, I was surprised that this was not mentioned earlier.

Old thread, still for future reference...:) even following works

git show-ref --head

by default HEAD is filtered out. Be careful about following though ; plural "heads" with a 's' at the end. The following command shows branches under "refs/heads"

In Visual Studio Code just press Alt and place your cursor to the edit place(where you want to edit) and right click to select.

I had the same question and I finally found the answer:

You need to handle BOTH the SelectionChanged event and the DropDownClosed like this:

In XAML:

<ComboBox Name="cmbSelect" SelectionChanged="ComboBox_SelectionChanged" DropDownClosed="ComboBox_DropDownClosed">
    <ComboBoxItem>1</ComboBoxItem>
    <ComboBoxItem>2</ComboBoxItem>
    <ComboBoxItem>3</ComboBoxItem>
</ComboBox>

In C#:

private bool handle = true;
private void ComboBox_DropDownClosed(object sender, EventArgs e) {
  if(handle)Handle();
  handle = true;
}

private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e) {
  ComboBox cmb = sender as ComboBox;
  handle = !cmb.IsDropDownOpen;
  Handle();
}

private void Handle() {
  switch (cmbSelect.SelectedItem.ToString().Split(new string[] { ": " }, StringSplitOptions.None).Last())
  { 
      case "1":
          //Handle for the first combobox
          break;
      case "2":
          //Handle for the second combobox
          break;
      case "3":
          //Handle for the third combobox
          break;
  }
}

For those using gcloud build:

gcloud build ignores .dockerignore and looks instead for .gcloudignore

Use:

cp .dockerignore .gcloudignore

Source

display: inline-block is your friend you just need all three parts of the construct - before, the "block", after - to be one, then you can vertically align them all to the middle:

Working Example

(it looks like your picture anyway ;))

CSS:

p, div {
  display: inline-block; 
  vertical-align: middle;
}
p, div {
  display: inline !ie7; /* hack for IE7 and below */
}

table {
  background: #000; 
  color: #fff; 
  font-size: 16px; 
  font-weight: bold; margin: 0 10px;
}

td {
  padding: 5px; 
  text-align: center;
}

HTML:

<p>some text</p> 
<div>
  <table summary="">
  <tr><td>A</td></tr>
  <tr><td>B</td></tr>
  <tr><td>C</td></tr>
  <tr><td>D</td></tr>
  </table>
</div> 
<p>continues afterwards</p>

My test string for the following:

testing='12345,abc,123,54321,ab15234,123456,52341';

If I understand your question, you'd want ["12345", "54321", "15234", "52341"].

If JS engines supported regexp lookbehinds, you could do:

testing.match(/(?<!\d)\d{5}(?!\d)/g)

Since it doesn't currently, you could:

testing.match(/(?:^|\D)(\d{5})(?!\d)/g)

and remove the leading non-digit from appropriate results, or:

pentadigit=/(?:^|\D)(\d{5})(?!\d)/g;
result = [];
while (( match = pentadigit.exec(testing) )) {
    result.push(match[1]);
}

Note that for IE, it seems you need to use a RegExp stored in a variable rather than a literal regexp in the while loop, otherwise you'll get an infinite loop.

I cannot comment Palehorse's answer so I added my own answer. Palehorse's logic is ok but efficiency can be bad with big data sets.

DELETE FROM some_child_table sct 
 WHERE exists (SELECT FROM some_Table st 
                WHERE sct.some_fk_fiel=st.some_id);

DELETE FROM some_table;

It is faster if you have indexes on columns and data set is bigger than few records.

Java 5+ has all the tools you need for this kind of thing. You will want to:

1. Put all your Producers in one ExecutorService;
2. Put all your Consumers in another ExecutorService;
3. If necessary, communicate between the two using a BlockingQueue.

I say "if necessary" for (3) because from my experience it's an unnecessary step. All you do is submit new tasks to the consumer executor service. So:

final ExecutorService producers = Executors.newFixedThreadPool(100);
final ExecutorService consumers = Executors.newFixedThreadPool(100);
while (/* has more work */) {
  producers.submit(...);
}
producers.shutdown();
producers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
consumers.shutdown();
consumers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

So the producers submit directly to consumers.

On my Mac, I wrote this code in my Terminal:

xxx-MacBook-Pro:~ xxx$ cd /Users/xxx/Documents/0_Software/adt20140702/sdk/platform-tools/

xxx-MacBook-Pro:platform-tools xxx$ ./adb kill-server

xxx-MacBook-Pro:platform-tools xxx$ ./adb start-server

• daemon not running. starting it now on port 5037 *
• daemon started successfully *

Hope this help.

For those moments when you really want to avoid building lists:

import re
import operator
from functools import reduce
count = reduce(operator.add, (1 for _ in re.finditer(my_pattern, my_string))) 

Sometimes you might need to operate on huge strings. This might help.

If you are sure that you selected the Generic iOS device and still can't see the option, then you simply have to restart Xcode.

Framework 4: no need to use StreamWriter:

System.IO.File.WriteAllLines("SavedLists.txt", Lists.verbList);

Use DateTime.ToString with the specified format MM.dd.yyyy:

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

Here, MM means the month from 01 to 12, dd means the day from 01 to 31 and yyyy means the year as a four-digit number.

All user installed apks are located in /data/app/, but you can only access this if you are rooted(afaik, you can try without root and if it doesn't work, rooting isn't hard. I suggest you search xda-developers for rooting instructions)

Use Root explorer or ES File Explorer to access /data/app/ (you have to keep going "up" until you reach the root directory /, kind of like C: in windows, before you can see the data directory(folder)). In ES file explorer you must also tick a checkbox in settings to allow going up to the root directory.

When you are in there you will see all your applications apks, though they might be named strangely. Just copy the wanted .apk and paste in the sd card, after that you can copy it to your computer and when you want to install it just open the .apk in a file manager (be sure to have install from unknown sources enabled in android settings). Even if you only want to send over bluetooth I would recommend copying it to the SD first.

PS Note that paid apps probably won't work being copied this way, since they usually check their licence online. PPS Installing an app this way may not link it with google play(you won't see it in my apps and it won't get updates).

You can use as below,

Select X.a, X.b, Y.c from (
                Select X.a as a, sum (b) as sum_b from name_table X
                group by X.a)X
left join from name_table Y on Y.a = X.a

Example;

CREATE TABLE #products (
    product_name VARCHAR(MAX),
    code varchar(3),
    list_price [numeric](8, 2) NOT NULL
);

INSERT INTO #products VALUES ('paku', 'ACE', 2000)
INSERT INTO #products VALUES ('paku', 'ACE', 2000)
INSERT INTO #products VALUES ('Dinding', 'ADE', 2000)
INSERT INTO #products VALUES ('Kaca', 'AKB', 2000)
INSERT INTO #products VALUES ('paku', 'ACE', 2000)

--SELECT * FROM #products 
SELECT distinct x.code, x.SUM_PRICE, product_name FROM (SELECT code, SUM(list_price) as SUM_PRICE From #products 
               group by code)x
left join #products y on y.code=x.code

DROP TABLE #products

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

You can use regex and delete non-digits.

str = str.replaceAll("\\D+","");

Check out fontsquirrel. They have a web font generator, which will also spit out a suitable stylesheet for your font (look for "@font-face kit"). This stylesheet can be included in your own, or you can use it as a template.

<style>
ul li{display: table;}  
</style>

works perfectly

Here is a non-regex heap allocation friendly fast solution which was what I was looking for.

Unsafe edition.

public static unsafe void ToAlphaNumeric(ref string input)
{
    fixed (char* p = input)
    {
        int offset = 0;
        for (int i = 0; i < input.Length; i++)
        {
            if (char.IsLetterOrDigit(p[i]))
            {
                p[offset] = input[i];
                offset++;
            }
        }
        ((int*)p)[-1] = offset; // Changes the length of the string
        p[offset] = '\0';
    }
}

And for those who don't want to use unsafe or don't trust the string length hack.

public static string ToAlphaNumeric(string input)
{
    int j = 0;
    char[] newCharArr = new char[input.Length];

    for (int i = 0; i < input.Length; i++)
    {
        if (char.IsLetterOrDigit(input[i]))
        {
            newCharArr[j] = input[i];
            j++;
        }
    }

    Array.Resize(ref newCharArr, j);

    return new string(newCharArr);
}

^{This question is old, but was referenced in a new question on dba.SE. I feel the best solutions haven't been provided, yet, so I am adding another one.}

First off, assuming referential integrity (typically enforced with foreign key constraints) you do not need to join to the table movie at all. That's dead freight in your query. All answers so far fail to point that out.

Can I do a max(count(*)) in SQL?

To answer the question in the title: Yes, in Postgres 8.4 (released 2009-07-01, before this question was asked) or later you can achieve that by nesting an aggregate function in a window function:

SELECT c.yr, count(*) AS ct, max(count(*)) OVER () AS max_ct
FROM   actor   a
JOIN   casting c ON c.actorid = a.id
WHERE  a.name = 'John Travolta'
GROUP  BY c.yr;

Consider the sequence of events in a SELECT query:

• Best way to get result count before LIMIT was applied

The (possible) downside: window functions do not aggregate rows. You get all rows left after the aggregate step. Useful in some queries, but not ideal for this one.

To get one row with the highest count, you can use ORDER BY ct LIMIT 1 like @wolph hinted:

SELECT c.yr, count(*) AS ct
FROM   actor   a
JOIN   casting c ON c.actorid = a.id
WHERE  a.name = 'John Travolta'
GROUP  BY c.yr
ORDER  BY ct DESC
LIMIT  1;

Using only basic SQL features available in any halfway decent RDBMS - the LIMIT implementation varies:

• SQL select elements where sum of field is less than N

Or you can get one row per group with the highest count with DISTINCT ON (only Postgres):

• Select first row in each GROUP BY group?

Answer

But you asked for:

... rows for which count(*) is max.

Possibly more than one. The most elegant solution is with the window function rank() in a subquery. Ryan provided a query but it can be simpler (details in my answer above):

SELECT yr, ct
FROM  (
   SELECT c.yr, count(*) AS ct, rank() OVER (ORDER BY count(*) DESC) AS rnk
   FROM   actor   a
   JOIN   casting c ON c.actorid = a.id
   WHERE  a.name = 'John Travolta'
   GROUP  BY c.yr
   ) sub
WHERE  rnk = 1;

All major RDBMS support window functions nowadays. Except MySQL and forks (MariaDB seems to have implemented them at last in version 10.2).

Be sure to have both objects created in controller: @post and @comment for the post, eg:

@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)

Then in view:

<%= form_for([@post, @comment]) do |f| %>

Be sure to explicitly define the array in the form_for, not just comma separated like you have above.

I had the same problem and, in my case, the problem was that python was looking for packages in some ordered locations, first of all the default computer one where default old packages are.

To check what your python is looking for you can do:

>>> import sys
>>> print '\n'.join(sys.path)

This was outputting the directory '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python' before pip or brew or port folders.

The simple solution is:

export PYTHONPATH="/Library/Python/2.7/site-packages:$PYTHONPATH"

This worked well for me, I advise you to add this line to your home bash_profile file for the next time. Remember that sys.path is built using the current working directory, followed by the directories in the PYTHONPATH environment variable. Then there are the installation-dependent default dirs.

I had exactly this issue using requests. Thanks to Christophe Roussy for his explanation.

To debug, I used:

response = requests.get(url)
logger.info(type(response))

I was getting a 404 response back from the API.

Datatype: array_name:datatype[]=[]; Example string: users:string[]=[];

For array of objects:

Objecttype: object_name:objecttype[]=[{}]; Example user: Users:user[]=[{}];

And if in some cases it's coming undefined in binding, make sure to initialize it on Oninit().

Here's a variation on some of the above answers that supports multiple transforms (keyval, key, value):

import { Pipe, PipeTransform } from '@angular/core';

type Args = 'keyval'|'key'|'value';

@Pipe({
  name: 'mapToIterable',
  pure: false
})
export class MapToIterablePipe implements PipeTransform {
  transform(obj: {}, arg: Args = 'keyval') {
    return arg === 'keyval' ?
        Object.keys(obj).map(key => ({key: key, value: obj[key]})) :
      arg === 'key' ?
        Object.keys(obj) :
      arg === 'value' ?
        Object.keys(obj).map(key => obj[key]) :
      null;
  }
}

Usage

map = {
    'a': 'aee',
    'b': 'bee',
    'c': 'see'
}

<div *ngFor="let o of map | mapToIterable">{{o.key}}: {{o.value}}</div>
  <div>a: aee</div>
  <div>b: bee</div>
  <div>c: see</div>

<div *ngFor="let o of map | mapToIterable:'keyval'">{{o.key}}: {{o.value}}</div>
  <div>a: aee</div>
  <div>b: bee</div>
  <div>c: see</div>

<div *ngFor="let k of map | mapToIterable:'key'">{{k}}</div>
  <div>a</div>
  <div>b</div>
  <div>c</div>

<div *ngFor="let v of map | mapToIterable:'value'">{{v}}</div>
  <div>aee</div>
  <div>bee</div>
  <div>see</div>

With rails >= 3.0, you can simply use the placeholder option.

f.text_field :attr, placeholder: "placeholder text"

The error is telling you that POI couldn't find a core part of the OOXML file, in this case the content types part. Your file isn't a valid OOXML file, let alone a valid .xlsx file. It is a valid zip file though, otherwise you'd have got an earlier error

Can Excel really load this file? I'd expect it wouldn't be able to, as the exception is most commonly triggered by giving POI a regular .zip file! I suspect your file isn't valid, hence the exception

.

Update: In Apache POI 3.15 (from beta 1 onwards), there's a more helpful set of Exception messages for the more common causes of this problem. You'll now get more descriptive exceptions in this case, eg ODFNotOfficeXmlFileException and OLE2NotOfficeXmlFileException. This raw form should only ever show up if POI really has no clue what you've given it but knows it's broken or invalid.

My comment is mainly in reference to point #3: under what circumstances is ON UPDATE CASCADE applicable if we're assuming that the parent key is not updateable? Here is one case.

I am dealing with a replication scenario in which multiple satellite databases need to be merged with a master. Each satellite is generating data on the same tables, so merging of the tables to the master leads to violations of the uniqueness constraint. I'm trying to use ON UPDATE CASCADE as part of a solution in which I re-increment the keys during each merge. ON UPDATE CASCADE should simplify this process by automating part of the process.

What I have done in this case is pass an array, where the key is the parameter name, and the value is the value.

$optional = array(
  "param" => $param1,
  "param2" => $param2
);

function func($required, $requiredTwo, $optional) {
  if(isset($optional["param2"])) {
    doWork();
  }
}

Mind you that this is a highly opinion based question, so I stopped making fjords and made a quick table

Now library comparison is hard because on many parameters, all the four pretty much do the same thing, except possibly for Fresco because there is a whole bunch of new memory level optimizations in it.So let me know if certain parameters you'd like to see a comparison for based on my experience.

Having used Fresco the least, the answer might evolve as I continue to use and understand it for current exploits. The used personally is having used the library atleast once in a completed app.

*Note - Fresco now supports GIF as well as WebP animations

Without less, ans simply for a given div :

In a css :

.footer {
background-color: #ab0000;
padding-top: 40px;
padding-bottom: 10px;
border-radius:5px;
}

In html :

 <div class="footer">
        <p>blablabla</p>
      </div>

You can have a counter (freePosition), which will track the next free place in an array of size n.

Not that there haven't been enough answers to this question, but there is a repeat function; just need to make a list of and then join the output:

from itertools import repeat

def rep(s,n):
  ''.join(list(repeat(s,n))

Use dotPeek by JetBrains.

dotPeek is a free tool based on ReSharper. It can reliably decompile any .NET assembly into C# or IL code.

You've declared the class Thing as a non-static inner class. That means it must be associated with an instance of the Hello class.

In your code, you're trying to create an instance of Thing from a static context. That is what the compiler is complaining about.

There are a few possible solutions. Which solution to use depends on what you want to achieve.

• Move Thing out of the Hello class.

• Change Thing to be a static nested class.

  static class Thing
  

• Create an instance of Hello before creating an instance of Thing.

  public static void main(String[] args)
  {
      Hello h = new Hello();
      Thing thing1 = h.new Thing(); // hope this syntax is right, typing on the fly :P
  }
  

The last solution (a non-static nested class) would be mandatory if any instance of Thing depended on an instance of Hello to be meaningful. For example, if we had:

public class Hello {
    public int enormous;

    public Hello(int n) {
        enormous = n;
    }

    public class Thing {
        public int size;

        public Thing(int m) {
            if (m > enormous)
                size = enormous;
            else
                size = m;
        }
    }
    ...
}

any raw attempt to create an object of class Thing, as in:

Thing t = new Thing(31);

would be problematic, since there wouldn't be an obvious enormous value to test 31 against it. An instance h of the Hello outer class is necessary to provide this h.enormous value:

...
Hello h = new Hello(30);
...
Thing t = h.new Thing(31);
...

Because it doesn't mean a Thing if it doesn't have a Hello.

For python datasets you can use an index.

tmpColumnsSQL = ("show columns in dim.date_dim")
hiveCursor.execute(tmpColumnsSQL)
columnlist = hiveCursor.fetchall()

for columns in jayscolumnlist:
    print columns[0]

for i in range(len(jayscolumnlist)):    
    print columns[i][0])

Use shutil.copyfileobj.

It automatically reads the input files chunk by chunk for you, which is more more efficient and reading the input files in and will work even if some of the input files are too large to fit into memory:

import shutil

with open('output_file.txt','wb') as wfd:
    for f in ['seg1.txt','seg2.txt','seg3.txt']:
        with open(f,'rb') as fd:
            shutil.copyfileobj(fd, wfd)

Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.

You can find some examples of this here, here (code is taken here), and here.

You can create a POJO class for this, but you need to add some extra code to make it Parcelable. Have a look at the implementation.

public class Student implements Parcelable{
        private String id;
        private String name;
        private String grade;

        // Constructor
        public Student(String id, String name, String grade){
            this.id = id;
            this.name = name;
            this.grade = grade;
       }
       // Getter and setter methods
       .........
       .........

       // Parcelling part
       public Student(Parcel in){
           String[] data = new String[3];

           in.readStringArray(data);
           // the order needs to be the same as in writeToParcel() method
           this.id = data[0];
           this.name = data[1];
           this.grade = data[2];
       }

       @?verride
       public int describeContents(){
           return 0;
       }

       @Override
       public void writeToParcel(Parcel dest, int flags) {
           dest.writeStringArray(new String[] {this.id,
                                               this.name,
                                               this.grade});
       }
       public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
           public Student createFromParcel(Parcel in) {
               return new Student(in); 
           }

           public Student[] newArray(int size) {
               return new Student[size];
           }
       };
   }

Once you have created this class, you can easily pass objects of this class through the Intent like this, and recover this object in the target activity.

intent.putExtra("student", new Student("1","Mike","6"));

Here, the student is the key which you would require to unparcel the data from the bundle.

Bundle data = getIntent().getExtras();
Student student = (Student) data.getParcelable("student");

This example shows only String types. But, you can parcel any kind of data you want. Try it out.

EDIT: Another example, suggested by Rukmal Dias.

I think the only way will be to stop the process which has opened the port.

os.makedirs is what you need. For chmod or chown you'll have to use os.walk and use it on every file/dir yourself.

Like this. Make sure you drop the temp table (at the end of the code block, after you're done with it) or it will error on subsequent runs.

SELECT  
    tblMEP_Sites.Name AS SiteName, 
    convert(varchar(10),BillingMonth ,101) AS BillingMonth, 
    SUM(Consumption) AS Consumption
INTO 
    #MyTempTable
FROM 
    tblMEP_Projects
    JOIN tblMEP_Sites
        ON tblMEP_Projects.ID = tblMEP_Sites.ProjectID
    JOIN tblMEP_Meters
        ON tblMEP_Meters.SiteID = tblMEP_Sites.ID
    JOIN tblMEP_MonthlyData
        ON tblMEP_MonthlyData.MeterID = tblMEP_Meters.ID
    JOIN tblMEP_CustomerAccounts
        ON tblMEP_CustomerAccounts.ID = tblMEP_Meters.CustomerAccountID
    JOIN tblMEP_UtilityCompanies
        ON tblMEP_UtilityCompanies.ID = tblMEP_CustomerAccounts.UtilityCompanyID
    JOIN tblMEP_MeterTypes
        ON tblMEP_UtilityCompanies.UtilityTypeID = tblMEP_MeterTypes.ID
WHERE 
    tblMEP_Projects.ID = @ProjectID
    AND tblMEP_MonthlyData.BillingMonth Between @StartDate AND @EndDate
    AND tbLMEP_MeterTypes.ID = @MeterTypeID
GROUP BY 
    BillingMonth, tblMEP_Sites.Name

DROP TABLE #MyTempTable

You need the following functions to do this in PHP:

strpos Find the position of the first occurrence of a substring in a string

strrpos Find the position of the last occurrence of a substring in a string

substr Return part of a string

Here's the signature of the substr function:

string substr ( string $string , int $start [, int $length ] )

The signature of the substring function (Java) looks a bit different:

string substring( int beginIndex, int endIndex )

substring (Java) expects the end-index as the last parameter, but substr (PHP) expects a length.

It's not hard, to get the desired length by the end-index in PHP:

$sub = substr($str, $start, $end - $start);

Here is the working code

$start = strpos($message, '-') + 1;
if ($req_type === 'RMT') {
    $pt_password = substr($message, $start);
}
else {
    $end = strrpos($message, '-');
    $pt_password = substr($message, $start, $end - $start);
}

Separate the business rules for age from the actions e.g. (NB just typed, not checked)

enum eAgerange { eChild, eYouth, eAdult, eAncient};
eAgeRange ar;
if(age <= 8) ar = eChild;
else if(age <= 15) ar = eYouth;
else if(age <= 100) ar = eAdult;
else ar = eAncient;
switch(ar)
{
 case eChild: 
     // action
 case eYouth:
     // action
 case eAdult:
     // action
 case eAncient:
     // action
 default: throw new NotImplementedException($"Oops {ar.ToString()} not handled");
}   

`

The most valuable thing it does is give you another string identical to the first, without requiring you to allocate memory (location and size) yourself. But, as noted, you still need to free it (but which doesn't require a quantity calculation, either.)

You have to cast, I'm afraid:

f((byte)0);

I believe that will perform the appropriate conversion at compile-time instead of execution time, so it's not actually going to cause performance penalties. It's just inconvenient :(

Translate composed UInt32 color Value to CSS in .NET

I know the question applies to 3 input values (red green blue). But there may be the situation where you already have a composed 32bit Value. It looks like you want to send the data to some HTML CSS renderer (because of the #HEX format). Actually CSS wants you to print 6 or at least 3 zero filled hex digits here. so #{0:X06} or #{0:X03} would be required. Due to some strange behaviour, this always prints 8 digits instead of 6.

Solve this by:

String.Format("#{0:X02}{1:X02}{2:X02}", (Value & 0x00FF0000) >> 16, (Value & 0x0000FF00) >> 8, (Value & 0x000000FF) >> 0)

I know I'm late to the game, but you can just do ?id=14&like=like by using http build query as follows:

http_build_query(array_merge($_GET, array("like"=>"like")))

Whatever GET parameters you had will still be there and if like was a parameter before it will be overwritten, otherwise it will be included at the end.

Here is an answer from a bit of an abstract, graph theoretic angle:

Let's simplify the problem by only looking at (directed) dependency graphs between stateful objects.

An extremely simple answer can be illustrated by considering two limiting cases of dependency graphs:

The 1st limiting case: a cluster graphs .

A cluster graph is the most perfect realisation of a high cohesion and low coupling (given a set of cluster sizes) dependency graph.

The dependence between clusters is maximal (fully connected), and inter cluster dependence is minimal (zero).

This is an abstract illustration of the answer in one of the limiting cases.

The 2nd limiting case is a fully connected graph, where everything depends on everything.

Reality is somewhere in between, the closer to the cluster graph the better, in my humble understanding.

From another point of view: when looking at a directed dependency graph, ideally it should be acyclic, if not then cycles form the smallest clusters/components.

One step up/down the hierarchy corresponds to "one instance" of loose coupling, tight cohesion in a software but it is possible to view this loose coupling/tight cohesion principle as a repeating phenomena at different depths of an acyclic directed graph (or on one of its spanning tree's).

Such decomposition of a system into a hierarchy helps to beat exponential complexity (say each cluster has 10 elements). Then at 6 layers it's already 1 million objects:

10 clusters form 1 supercluster, 10 superclusters form 1 hypercluster and so on ... without the concept of tight cohesion, loose coupling, such a hierarchical architecture would not be possible.

So this might be the real importance of the story and not just the high cohesion low coupling within two layers only. The real importance becomes clear when considering higher level abstractions and their interactions.

There's a standard Windows component which can achieve what you're trying to do: BITS. It has been included in Windows since XP and 2000 SP3.

Run:

bitsadmin.exe /transfer "JobName" http://download.url/here.exe C:\destination\here.exe

The job name is simply the display name for the download job - set it to something that describes what you're doing.

This example pipes the complete contents of the repository to a file, which you can then quickly search for filenames within an editor:

svn list -R svn://svn > filelist.txt

This is useful if the repository is relatively static and you want to do rapid searches without having to repeatedly load everything from the SVN server.

I needed the same thing, and although AFAIK this cannot be done programmatically, it worked for me.

I just went to Start --> Uninstall a program, and scrolled down until I found the VC++ redistributable, which includes a version number. Googling the version number, told me it belongs to VS2012 SP1.

In fact, it is very easy.

composer update

will do all this for you, but it will also update the other packages.

To remove a package without updating the others, specifiy that package in the command, for instance:

composer update monolog/monolog

will remove the monolog/monolog package.

Nevertheless, there may remain some empty folders or files that cannot be removed automatically, and that have to be removed manually.

You have two choices to do this.

The Quick and Dirty is selecting your files (using ctrl) in Project Explorer view, right-click them, choose Replace with... and then you choose the best option for you, from Latest from Repository, or some Branch version. After getting those files you modify them (with a space, or fix something, your call and commit them to create a newer revision.

A more clean way is choosing Merge at team menu and navigate through the wizard that will help you to recovery the old version in the actual revision.

Both commands have their command-line equivalents: svn revert and svn merge.

Actually even font-awesome CSS has a similar strategy for setting their icon styles. If you want to get a quick hold of the icon code, check the non-minified font-awesome.css file and there they are....each font in its purity.

You can't initialize arrays like this:

int cipher[Array_size][Array_size]=0;

The syntax for 2D arrays is:

int cipher[Array_size][Array_size]={{0}};

Note the curly braces on the right hand side of the initialization statement.

for 1D arrays:

int tomultiply[Array_size]={0};

Just add public properties to the user control.

You can add [Category("MyCategory")] and [Description("A property that controls the wossname")] attributes to make it nicer, but as long as it's a public property it should show up in the property panel.

I used these options to convert to the H.264/AAC .mp4 format for HTML5 playback (I think it may help other guys with this problem in some way):

ffmpeg -i input.flv -vcodec mpeg4 -acodec aac output.mp4

UPDATE

As @LordNeckbeard mentioned, the previous line will produce MPEG-4 Part 2 (back in 2012 that worked somehow, I don't remember/understand why). Use the libx264 encoder to produce the proper video with H.264/AAC. To test the output file you can just drag it to a browser window and it should playback just fine.

ffmpeg -i input.flv -vcodec libx264 -acodec aac output.mp4

Steps:

1. Open your phpMyadmin dashboard
2. go to user accounts
3. on the user section Get the root user and click [ Edit privileges ]
4. in the top section you will find change password button [ click on it ]
5. make a good pass and fill 2 pass field .
6. now hit the Go button.

7 . now open your xampp dir ( c:/xampp ) --> 8 . to phpMyadmin dir [C:\xampp\phpMyAdmin]

9. open [ config.inc.php ] file with any text editor

10 .find [ $cfg['Servers'][$i]['auth_type'] = 'config'; ]line and replace 'config' to ‘cookie’

11. go to [ $cfg['Servers'][$i]['AllowNoPassword'] = true; ] this line change ‘true’ to ‘false’.

last : save the file .

Just a minor addition: The speed difference between memcpy() and std::copy() can vary quite a bit depending on if optimizations are enabled or disabled. With g++ 6.2.0 and without optimizations memcpy() clearly wins:

Benchmark             Time           CPU Iterations
---------------------------------------------------
bm_memcpy            17 ns         17 ns   40867738
bm_stdcopy           62 ns         62 ns   11176219
bm_stdcopy_n         72 ns         72 ns    9481749

When optimizations are enabled (-O3), everything looks pretty much the same again:

Benchmark             Time           CPU Iterations
---------------------------------------------------
bm_memcpy             3 ns          3 ns  274527617
bm_stdcopy            3 ns          3 ns  272663990
bm_stdcopy_n          3 ns          3 ns  274732792

The bigger the array the less noticeable the effect gets, but even at N=1000 memcpy() is about twice as fast when optimizations aren't enabled.

Source code (requires Google Benchmark):

#include <string.h>
#include <algorithm>
#include <vector>
#include <benchmark/benchmark.h>

constexpr int N = 10;

void bm_memcpy(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    memcpy(r.data(), a.data(), N * sizeof(int));
  }
}

void bm_stdcopy(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    std::copy(a.begin(), a.end(), r.begin());
  }
}

void bm_stdcopy_n(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    std::copy_n(a.begin(), N, r.begin());
  }
}

BENCHMARK(bm_stdcopy);
BENCHMARK(bm_stdcopy_n);

What I have found is that simply wrapping code in the componentDidMount or componentDidUpdate with a setTimeout with a time of 0 milliseconds ensures that the browser DOM has been updated with the React changes before executing the setTimeout function.

Like this:

componentDidMount() {
    setTimeout(() => {
        $("myclass") //  $ is available here
    }, 0)
}

This puts the anonymous function on the JS Event Queue to run immediately after the currently running React stack frame has completed.

One more way to do this is:

git config remote.origin.url https://github.com/abc/abc.git

To see the existing URL just do:

git config remote.origin.url

Example from https://github.com/ffmike/jquery-validate

 <label for="spam_email">
     <input type="checkbox" class="checkbox" id="spam_email" value="email" name="spam[]" validate="required:true, minlength:2" /> Spam via E-Mail </label>
 <label for="spam_phone">
     <input type="checkbox" class="checkbox" id="spam_phone" value="phone" name="spam[]" /> Spam via Phone </label>
 <label for="spam_mail">
     <input type="checkbox" class="checkbox" id="spam_mail" value="mail" name="spam[]" /> Spam via Mail </label>
 <label for="spam[]" class="error">Please select at least two types of spam.</label>

The same without field "validate" in tags only using javascript:

$("#testform").validate({ 
    rules: { 
            "spam[]": { 
                    required: true, 
                    minlength: 1 
            } 
    }, 
    messages: { 
            "spam[]": "Please select at least two types of spam."
    } 
}); 

And if you need different names for inputs, you can use somethig like this:

<input type="hidden" name="spam" id="spam"/>
<label for="spam_phone">
    <input type="checkbox" class="checkbox" id="spam_phone" value="phone" name="spam_phone" /> Spam via Phone</label>
<label for="spam_mail">
    <input type="checkbox" class="checkbox" id="spam_mail" value="mail" name="spam_mail" /> Spam via Mail </label>

Javascript:

 $("#testform").validate({ 
    rules: { 
        spam: { 
            required: function (element) {
                var boxes = $('.checkbox');
                if (boxes.filter(':checked').length == 0) {
                    return true;
                }
                return false;
            },
            minlength: 1 
        } 
    }, 
    messages: { 
            spam: "Please select at least two types of spam."
    } 
}); 

I have added hidden input before inputs and setting it to "required" if there is no selected checkboxes

Why not just do

if(BuildConfig.DEBUG)
  Log.d("tag","msg");

? No additional libraries needed, no proguard rules which tend to screw up the project and java compiler will just leave out bytecode for for this call when you make release build.
