import time  
current = time.time()

...job...
end = time.time()
diff = end - current

would that work for you?

Please try this code

$(this).animate({'width': 'toggle'});

See http://jsfiddle.net/qP8DY/24/

You can add a class (such as "success-dialog" in my example) to div#success, either directly in your HTML, or in your JavaScript by adding to the dialogClass option, as I've done.

$('#success').dialog({
    height: 50,
    width: 350,
    modal: true,
    resizable: true,
    dialogClass: 'no-close success-dialog'
});

Then just add the success-dialog class to your CSS rules as appropriate. To indicate an element with two (or more) classes applied to it, just write them all together, with no spaces in between. For example:

.ui-dialog.success-dialog {
    font-family: Verdana,Arial,sans-serif;
    font-size: .8em;
}

You can try DBVisualizer some features are not free, but you can get an evaluate license...

  private String formatDate(String date, String inputFormat, String outputFormat) {

    String newDate;
    DateFormat inputDateFormat = new SimpleDateFormat(inputFormat);
    inputDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
    DateFormat outputDateFormat = new SimpleDateFormat(outputFormat);
    try {
        newDate = outputDateFormat.format((inputDateFormat.parse(date)));
    } catch (Exception e) {
        newDate = "";
    }
    return newDate;

}

If you want to keep the heredoc indented for readability:

$ perl -pe 's/^\s*//' << EOF
     line 1
     line 2
EOF

The built-in method for supporting indented heredoc in Bash only supports leading tabs, not spaces.

Perl can be replaced with awk to save a few characters, but the Perl one is probably easier to remember if you know basic regular expressions.

Hello you can make use of input and output. Input let you to pass variable form parent to child. Output the same but from child to parent.

The easiest way is to pass "startdate" and "endDate" as input

<calendar [startDateInCalendar]="startDateInSearch" [endDateInCalendar]="endDateInSearch" ></calendar>

In this way you have your startdate and enddate directly in search page. Let me know if it works, or think another way. Thanks

function myfunction() {
     if(a == 'stop') 
         return false;
}

return false; is much better than just return;

SELECT CLASS,
isnull([AZ],0),
isnull([CA],0),
isnull([TX],0)
FROM #TEMP
PIVOT (SUM(DATA)
FOR STATE IN ([AZ], [CA], [TX])) AS PVT
ORDER BY CLASS

git fetch --all
git checkout origin/master -- <your_file_path>
git add <your_file_path>
git commit -m "<your_file_name> updated"

This is assuming you are pulling the file from origin/master.

You have extra spaces after END; that cause the heredoc not terminated.

This is a sample code I used to counter the problem.

\begin{frame}{Topic 1}
Topic of the figures
\begin{figure}
\captionsetup[subfloat]{position=top,labelformat=empty}
\only<1>{\subfloat[Fig. 1]{\includegraphics{figure1.jpg}}}
\only<2>{\subfloat[Fig. 2]{\includegraphics{figure2.jpg}}}
\only<3>{\subfloat[Fig. 3]{\includegraphics{figure3.jpg}}}
\end{figure}
\end{frame}

You set the DisplayMemberPath and the SelectedValuePath to "Name", so I assume that you have a class PhoneBookEntry with a public property Name.

Have you set the DataContext to your ConnectionViewModel object?

I copied you code and made some minor modifications, and it seems to work fine. I can set the viewmodels PhoneBookEnty property and the selected item in the combobox changes, and I can change the selected item in the combobox and the view models PhoneBookEntry property is set correctly.

Here is my XAML content:

<Window x:Class="WpfApplication6.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300">
<Grid>
    <StackPanel>
        <Button Click="Button_Click">asdf</Button>
        <ComboBox ItemsSource="{Binding Path=PhonebookEntries}"
                  DisplayMemberPath="Name"
                  SelectedValuePath="Name"
                  SelectedValue="{Binding Path=PhonebookEntry}" />
    </StackPanel>
</Grid>
</Window>

And here is my code-behind:

namespace WpfApplication6
{

    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            ConnectionViewModel vm = new ConnectionViewModel();
            DataContext = vm;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ((ConnectionViewModel)DataContext).PhonebookEntry = "test";
        }
    }

    public class PhoneBookEntry
    {
        public string Name { get; set; }

        public PhoneBookEntry(string name)
        {
            Name = name;
        }

        public override string ToString()
        {
            return Name;
        }
    }

    public class ConnectionViewModel : INotifyPropertyChanged
    {
        public ConnectionViewModel()
        {
            IList<PhoneBookEntry> list = new List<PhoneBookEntry>();
            list.Add(new PhoneBookEntry("test"));
            list.Add(new PhoneBookEntry("test2"));
            _phonebookEntries = new CollectionView(list);
        }

        private readonly CollectionView _phonebookEntries;
        private string _phonebookEntry;

        public CollectionView PhonebookEntries
        {
            get { return _phonebookEntries; }
        }

        public string PhonebookEntry
        {
            get { return _phonebookEntry; }
            set
            {
                if (_phonebookEntry == value) return;
                _phonebookEntry = value;
                OnPropertyChanged("PhonebookEntry");
            }
        }

        private void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
        public event PropertyChangedEventHandler PropertyChanged;
    }
}

Edit: Geoffs second example does not seem to work, which seems a bit odd to me. If I change the PhonebookEntries property on the ConnectionViewModel to be of type ReadOnlyCollection, the TwoWay binding of the SelectedValue property on the combobox works fine.

Maybe there is an issue with the CollectionView? I noticed a warning in the output console:

System.Windows.Data Warning: 50 : Using CollectionView directly is not fully supported. The basic features work, although with some inefficiencies, but advanced features may encounter known bugs. Consider using a derived class to avoid these problems.

Edit2 (.NET 4.5): The content of the DropDownList can be based on ToString() and not of DisplayMemberPath, while DisplayMemberPath specifies the member for the selected and displayed item only.

The new File System Access API will make our life easy again :)

try {
    const [fileHandle] = await window.showOpenFilePicker();
    const file = await fileHandle.getFile();
    // ...
}
catch (e) {
    console.log('Cancelled, no file selected');
}

Browser support is very limited (Jan, 2021). The example code works well in Chrome Desktop 86.

In many cases,

display:inline;

is enough.

But in some cases, you have to add following:

clear:none;

You could also type 'conda list' in a command line. This will print out the installed modules with the version numbers. The path within your file structure will be printed at the top of this list.

If you want to skip current iteration, use continue;.

for(int i = 0; i < 5; i++){
    if (i == 2){
        continue;
    }
 }

Need to break out of the whole loop? Use break;

for(int i = 0; i < 5; i++){
    if (i == 2){
        break;
    }
}

If you need to break out of more than one loop use break someLabel;

outerLoop:                                           // Label the loop
for(int j = 0; j < 5; j++){
     for(int i = 0; i < 5; i++){
        if (i==2){
          break outerLoop;
        }
     }
  }

*Note that in this case you are not marking a point in code to jump to, you are labeling the loop! So after the break the code will continue right after the loop!

When you need to skip one iteration in nested loops use continue someLabel;, but you can also combine them all.

outerLoop:
for(int j = 0; j < 10; j++){
     innerLoop:
     for(int i = 0; i < 10; i++){
        if (i + j == 2){
          continue innerLoop;
        }
        if (i + j == 4){
          continue outerLoop;
        }
        if (i + j == 6){
          break innerLoop;
        }
        if (i + j == 8){
          break outerLoop;
        }
     }
  }

np.mean always computes an arithmetic mean, and has some additional options for input and output (e.g. what datatypes to use, where to place the result).

np.average can compute a weighted average if the weights parameter is supplied.

I know its been a while since the question was asked but I was able to find a solution:

int sockfd;
int option = 1;
sockfd = socket(AF_INET, SOCK_STREAM, 0);
setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &option, sizeof(option));

This set the socket able to be reused immediately.

I apologize if this is "wrong". I'm not very experienced with sockets

What about

listbox1.Items.Clear();

I know this is an old thread, but in the Android documentation I found a solution that worked very well for me...

new CountDownTimer(30000, 1000) {

    public void onTick(long millisUntilFinished) {
        mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
    }

    public void onFinish() {
        mTextField.setText("done!");
    }
}.start();

Hope this helps someone...

uintptr_t is an unsigned integer type that is capable of storing a data pointer. Which typically means that it's the same size as a pointer.

It is optionally defined in C++11 and later standards.

A common reason to want an integer type that can hold an architecture's pointer type is to perform integer-specific operations on a pointer, or to obscure the type of a pointer by providing it as an integer "handle".

If you review the process of SSL negotiation at Wikipedia, you will know that at the beginning ClientHello and ServerHello messages are sent between the browser and the server.

Only if the cyphers provided in ClientHello have overlapping items on the server, ServerHello message will contain a cypher that both sides support. Otherwise, SSL connection will not be initiated as there is no common cypher.

To resolve the problem, you need to install cyphers (usually at OS level), instead of trying hard on the browser (usually the browser relies on the OS). I am familiar with Windows and IE, but I know little about Linux and Firefox, so I can only point out what's wrong but cannot deliver you a solution.

Spark RDD (resilient distributed dataset) :

RDD is the core data abstraction API and is available since very first release of Spark (Spark 1.0). It is a lower-level API for manipulating distributed collection of data. The RDD APIs exposes some extremely useful methods which can be used to get very tight control over underlying physical data structure. It is an immutable (read only) collection of partitioned data distributed on different machines. RDD enables in-memory computation on large clusters to speed up big data processing in a fault tolerant manner. To enable fault tolerance, RDD uses DAG (Directed Acyclic Graph) which consists of a set of vertices and edges. The vertices and edges in DAG represent the RDD and the operation to be applied on that RDD respectively. The transformations defined on RDD are lazy and executes only when an action is called

Spark DataFrame :

Spark 1.3 introduced two new data abstraction APIs – DataFrame and DataSet. The DataFrame APIs organizes the data into named columns like a table in relational database. It enables programmers to define schema on a distributed collection of data. Each row in a DataFrame is of object type row. Like an SQL table, each column must have same number of rows in a DataFrame. In short, DataFrame is lazily evaluated plan which specifies the operations needs to be performed on the distributed collection of the data. DataFrame is also an immutable collection.

Spark DataSet :

As an extension to the DataFrame APIs, Spark 1.3 also introduced DataSet APIs which provides strictly typed and object-oriented programming interface in Spark. It is immutable, type-safe collection of distributed data. Like DataFrame, DataSet APIs also uses Catalyst engine in order to enable execution optimization. DataSet is an extension to the DataFrame APIs.

Other Differences -

You can use a LENGTH(that_string) minus the number of characters you want to remove in the SUBSTRING() select perhaps or use the TRIM() function.

I had an excel file 24MB in Size, thanks to over a 100 images within. I reduced the size to less than 5MB by the following steps:

1. Selected each Picture, cut it (CTRL X) and pasted it in special mode by ALT E S Bitmap option
2. To find which Bitmap was still large, One has to select one of the files per sheet, then do CTRL A. This will select all Images.
3. Double Click on any one image and the RESET Picture option appears on top.
4. Click on reset picture and all Images that are still large show up.
5. Do a CTRL Z (UNDO) and now again paste these balance images in BITMAP (*.BMP) like step 1.

It took me 2 days to figure this out as this wasnt listed in any help forum. Hope this response helps someone

Give a try to this

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    // TODO Auto-generated method stub

    FragmentManager manager = ((Fragment) object).getFragmentManager();
    FragmentTransaction trans = manager.beginTransaction();
    trans.remove((Fragment) object);
    trans.commit();

    super.destroyItem(container, position, object);
}

I believe

rgba( 0, 0, 0, 0.8 )

is equivalent in shade with #333.

Live demo: http://jsfiddle.net/8MVC5/1/

Based on the hint and link provided in Simone Giannis answer, this is my hack to fix this.

I am testing on uri.getAuthority(), because UNC path will report an Authority. This is a bug - so I rely on the existence of a bug, which is evil, but it apears as if this will stay forever (since Java 7 solves the problem in java.nio.Paths).

Note: In my context I will receive absolute paths. I have tested this on Windows and OS X.

(Still looking for a better way to do it)

package com.christianfries.test;

import java.io.File;
import java.net.MalformedURLException;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.URL;

public class UNCPathTest {

    public static void main(String[] args) throws MalformedURLException, URISyntaxException {
        UNCPathTest upt = new UNCPathTest();

        upt.testURL("file://server/dir/file.txt");  // Windows UNC Path

        upt.testURL("file:///Z:/dir/file.txt");     // Windows drive letter path

        upt.testURL("file:///dir/file.txt");        // Unix (absolute) path
    }

    private void testURL(String urlString) throws MalformedURLException, URISyntaxException {
        URL url = new URL(urlString);
        System.out.println("URL is: " + url.toString());

        URI uri = url.toURI();
        System.out.println("URI is: " + uri.toString());

        if(uri.getAuthority() != null && uri.getAuthority().length() > 0) {
            // Hack for UNC Path
            uri = (new URL("file://" + urlString.substring("file:".length()))).toURI();
        }

        File file = new File(uri);
        System.out.println("File is: " + file.toString());

        String parent = file.getParent();
        System.out.println("Parent is: " + parent);

        System.out.println("____________________________________________________________");
    }

}

I was having same issue, and the solution was working but with some alerts and warnings so here is full solution, the key was to check for existing DataTable object or not, if yes just clear the table and add jsonData, if not just create new.

            var table;
            if ($.fn.dataTable.isDataTable('#example')) {
                table = $('#example').DataTable();
                table.clear();
                table.rows.add(jsonData).draw();
            }
            else {
                table = $('#example').DataTable({
                    "data": jsonData,
                    "deferRender": true,
                    "pageLength": 25,
                    "retrieve": true,

Versions

• JQuery: 3.3.1
• DataTable: 1.10.20

This works fine for 2 tables. I have 3 tables and on clause has to link 2 conditions from 3 tables. My code:

from p in _dbContext.Products join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId join jpr in leftJoinQuery on new { VariantId = pv.Vid, ProductId = p.ProduktId } equals new { VariantId = jpr.Prices.VariantID, ProductId = jpr.Prices.ProduktID } into lj

But its showing error at this point: join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId

Error: The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

You have to add click event to an exist element. You can not add event to dom elements dynamic created. I you want to add event to them, you should bind event to an existed element using ".on".

$('p').on('click','selector_you_dynamic_created',function(){...});

.delegate should work,too.

What do you mean by "drop out and echo the error"? If you mean you want the script to terminate as soon as any command fails, then just do

set -e    # DON'T do this.  See commentary below.

at the start of the script (but note warning below). Do not bother echoing the error message: let the failing command handle that. In other words, if you do:

#!/bin/sh

set -e    # Use caution.  eg, don't do this
command1
command2
command3

and command2 fails, while printing an error message to stderr, then it seems that you have achieved what you want. (Unless I misinterpret what you want!)

As a corollary, any command that you write must behave well: it must report errors to stderr instead of stdout (the sample code in the question prints errors to stdout) and it must exit with a non-zero status when it fails.

However, I no longer consider this to be a good practice. set -e has changed its semantics with different versions of bash, and although it works fine for a simple script, there are so many edge cases that it is essentially unusable. (Consider things like: set -e; foo() { false; echo should not print; } ; foo && echo ok The semantics here are somewhat reasonable, but if you refactor code into a function that relied on the option setting to terminate early, you can easily get bitten.) IMO it is better to write:

 #!/bin/sh

 command1 || exit
 command2 || exit
 command3 || exit

or

#!/bin/sh

command1 && command2 && command3

Try this...

<div class="row">
    <div class="col-xs-3">
        Menu
    </div>
    <div class="col-xs-9">
        <div class="row">
          <div class="col-sm-4 col-sm-push-8">
          Right content
          </div>
          <div class="col-sm-8 col-sm-pull-4">
          Content
          </div>
       </div>
    </div>
</div>

Bootply

It can easly be done using JavaScript for reference see link JS String

EDIT it can easly done as. ;)

var url="/Controller/Action?id=11112&value=4444 ";
var parameter_Start_index=url.indexOf('?');
var action_URL = url.substring(0, parameter_Start_index);
alert('action_URL : '+action_URL);

Just do this:

r = "hello"
r = r[1:]
print(r) # ello

You can do it inline like this

<div style="margin:0px auto"></div>

or you can do it via class

<div class="x"><div>

in your css file or between <style></style> add this .x{margin:0px auto}

or you can simply use the center tag

  <center>
    <div></div>
  </center>

or if you using absolute position, you can do

.x{
   width: 140px;
   position: absolute;
   top: 0px;
   left: 50%;
   margin-left: -70px; /*half the size of width*/
}

For better log file (without the Chrome-debug nonsense) use:

--enable-logging --log-level=0

instead of --v=1 which is just too much info.

It will still provide the errors and warnings like you would typically see in the Chrome console.

update May 18, 2020: Actually, I think this is no longer true. I couldn't find the console messages within whatever this logging level is.

Put it inside your <footer> by all means, but the most fitting element is the small element.

The HTML5 spec for this says:

Small print typically features disclaimers, caveats, legal restrictions, or copyrights. Small print is also sometimes used for attribution, or for satisfying licensing requirements.

A couple of days ago I found a very nice solution of this problem. Read about it here. In two words Mike created a AsyncTaskManager that mediates ProgressDialog and AsyncTask. It's very easy to use this solution. You just need to include in your project several interfaces and several classes and in your activity write some simple code and nest your new AsyncTask from BaseTask. I also advice you to read comments because there are some useful tips.

The nice way to do this is to add a "test" npm script in package.json that calls mocha with the right arguments. This way your package.json also describes your test structure. It also avoids all these cross-platform issues in the other answers (double vs single quotes, "find", etc.)

To have mocha run all js files in the "test" directory:

"scripts": {
    "start": "node ./bin/www", -- not required for tests, just here for context
    "test": "mocha test/**/*.js"
  },

Then to run only the smoke tests call:

npm test

You can standardize the running of all tests in all projects this way, so when a new developer starts on your project or another, they know "npm test" will run the tests. There is good historical precedence for this (Maven, for example, most old school "make" projects too). It sure helps CI when all projects have the same test command.

Similarly, you might have a subset of faster "smoke" tests that you might want mocha to run:

"scripts": {
    "test": "mocha test/**/*.js"
    "smoketest": "mocha smoketest/**/*.js"
  },

Then to run only the smoke tests call:

npm smoketest

Another common pattern is to place your tests in the same directory as the source that they test, but call the test files *.spec.js. For example: src/foo/foo.js is tested by src/foo/foo.spec.js.

To run all the tests named *.spec.js by convention:

  "scripts": {
    "test": "mocha **/*.spec.js"
  },

Then to run all the tests call:

npm test

See the pattern here? Good. :) Consistency defeats mura.

You're not actually passing the model to the Partial, you're passing a new ViewDataDictionary<LetLord.Models.Tenant>(). Try this:

@model LetLord.Models.Tenant
<div class="row-fluid">
    <div class="span4 well-border">
         @Html.Partial("~/Views/Tenants/_TenantDetailsPartial.cshtml", Model)
    </div>
</div>

$('#el').prop('disabled', function(i, v) { return !v; });

The .prop() method accepts two arguments:

• Property name (disabled, checked, selected) anything that is either true or false
• Property value, can be:
  • (empty) - returns the current value.
  • boolean (true/false) - sets the property value.
  • function - Is executed for each found element, the returned value is used to set the property. There are two arguments passed; the first argument is the index (0, 1, 2, increases for each found element). The second argument is the current value of the element (true/false).

So in this case, I used a function that supplied me the index (i) and the current value (v), then I returned the opposite of the current value, so the property state is reversed.

I've got a solution for changing a value in specific CSS class. But it only works if you keep your CSS in the tag. If you just keep a link to your CSS from external files ex.

<style src='script.js'></style>

this solution won't work.

If your css looks like this for example:

<style id='style'>
.foo {
height:50px;
}
</style>

You can change a value of the tag using JS/jQuery.

I've written a function, perhaps it's not the best one but it works. You can improve it if you want.

function replaceClassProp(cl,prop,val){

if(!cl || !prop || !val){console.error('Wrong function arguments');return false;}


// Select style tag value

var tag = '#style';

    var style = $(tag).text();
    var str = style;

// Find the class you want to change
    var n = str.indexOf('.'+cl);
    str = str.substr(n,str.length);
    n = str.indexOf('}');
    str = str.substr(0,n+1);

    var before = str;

// Find specific property

    n = str.indexOf(prop);
    str = str.substr(n,str.length);
    n = str.indexOf(';');
    str = str.substr(0,n+1);

// Replace the property with values you selected

    var after = before.replace(str,prop+':'+val+';');
    style=style.replace(before,after);

// Submit changes

    $(tag).text(style);

}

Then just change the tag variable into your style tag id and exegute:

replaceClassProp('foo','height','50px');

The difference between this and $('.foo').css('height','50px'); is that when you do it with css method of jQuery, all elements that have .foo class will have visible style='height:50px' in DOM. If you do it my way, elements are untouched and the only thing youll see is class='foo'

Advantages

• Clear DOM
• You can modify the property you want without replacing the whole style

Disadvantages

• Only internal CSS
• You have to find specific style tag you want to edit

Hope it helps anyhow.

Your Question contains the first step, but you need width and height. you can get the width and height of the screen. Here is a small edit

//gets the screen width and height
double Width = MediaQuery.of(context).size.width;
double Height = MediaQuery.of(context).size.height;

Widget background = new Image.asset(
  asset.background,
  fit: BoxFit.fill,
  width: Width,
  height: Height,
);

return new Stack(
  children: <Widget>[
    background,
    foreground,
  ],
);

You can also use Width and Height to size other objects based on screen size.

ex: width: Height/2, height: Height/2 //using height for both keeps aspect ratio

if permission issue and you have ssh access in root folder

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

will resolve your error

SAX parser is working differently with a DOM parser, it neither load any XML document into memory nor create any object representation of the XML document. Instead, the SAX parser use callback function org.xml.sax.helpers.DefaultHandler to informs clients of the XML document structure.

SAX Parser is faster and uses less memory than DOM parser. See following SAX callback methods :

startDocument() and endDocument() – Method called at the start and end of an XML document. startElement() and endElement() – Method called at the start and end of a document element. characters() – Method called with the text contents in between the start and end tags of an XML document element.

1. XML file

Create a simple XML file.

<?xml version="1.0"?>
<company>
    <staff>
        <firstname>yong</firstname>
        <lastname>mook kim</lastname>
        <nickname>mkyong</nickname>
        <salary>100000</salary>
    </staff>
    <staff>
        <firstname>low</firstname>
        <lastname>yin fong</lastname>
        <nickname>fong fong</nickname>
        <salary>200000</salary>
    </staff>
</company>

2. XML parser:

Java file Use SAX parser to parse the XML file.

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class ReadXMLFile {
    public static void main(String argv[]) {

        try {
            SAXParserFactory factory = SAXParserFactory.newInstance();
            SAXParser saxParser = factory.newSAXParser();

            DefaultHandler handler = new DefaultHandler() {
                boolean bfname = false;
                boolean blname = false;
                boolean bnname = false;
                boolean bsalary = false;

                public void startElement(String uri, String localName,String qName, 
                            Attributes attributes) throws SAXException {

                    System.out.println("Start Element :" + qName);

                    if (qName.equalsIgnoreCase("FIRSTNAME")) {
                        bfname = true;
                    }

                    if (qName.equalsIgnoreCase("LASTNAME")) {
                        blname = true;
                    }

                    if (qName.equalsIgnoreCase("NICKNAME")) {
                        bnname = true;
                    }

                    if (qName.equalsIgnoreCase("SALARY")) {
                        bsalary = true;
                    }

                }

                public void endElement(String uri, String localName,
                    String qName) throws SAXException {

                    System.out.println("End Element :" + qName);

                }

                public void characters(char ch[], int start, int length) throws SAXException {

                    if (bfname) {
                        System.out.println("First Name : " + new String(ch, start, length));
                        bfname = false;
                    }

                    if (blname) {
                        System.out.println("Last Name : " + new String(ch, start, length));
                        blname = false;
                    }

                    if (bnname) {
                        System.out.println("Nick Name : " + new String(ch, start, length));
                        bnname = false;
                    }

                    if (bsalary) {
                        System.out.println("Salary : " + new String(ch, start, length));
                        bsalary = false;
                    }

                }

            };

            saxParser.parse("c:\\file.xml", handler);

        } catch (Exception e) {
           e.printStackTrace();
        }

    }

}

Result

Start Element :company
Start Element :staff
Start Element :firstname
First Name : yong
End Element :firstname
Start Element :lastname
Last Name : mook kim
End Element :lastname
Start Element :nickname
Nick Name : mkyong
End Element :nickname
and so on...

There's a solution:

import pyautogui
for i in range(1000):
    pyautogui.typewrite("a")

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

Typically you add a class selector to the :not() pseudo-class like so:

:not(.printable) {
    /* Styles */
}

:not([attribute]) {
    /* Styles */
}

But if you need better browser support (IE8 and older don't support :not()), you're probably better off creating style rules for elements that do have the "printable" class. If even that isn't feasible despite what you say about your actual markup, you may have to work your markup around that limitation.

Keep in mind that, depending on the properties you're setting in this rule, some of them may either be inherited by descendants that are .printable, or otherwise affect them one way or another. For example, although display is not inherited, setting display: none on a :not(.printable) will prevent it and all of its descendants from displaying, since it removes the element and its subtree from layout completely. You can often get around this by using visibility: hidden instead which will allow visible descendants to show, but the hidden elements will still affect layout as they originally did. In short, just be careful.

A concise way is to use a tuple as key-value pair:

const keyVal: [string, string] =  ["key", "value"] // explicit type
// or
const keyVal2 = ["key", "value"] as const // inferred type with const assertion

[key, value] tuples also ensure compatibility to JS built-in objects:

• Object, esp. Object.entries, Object.fromEntries
• Map, esp. Map.prototype.entries and new Map() constructor
• Set, esp. Set.prototype.entries

You can create a generic KeyValuePair type for reusability:

type KeyValuePair<K extends string | number, V = unknown> = [K, V]
const kv: KeyValuePair<string, string> = ["key", "value"]

TS 4.0: Named tuples

Upcoming TS 4.0 provides named/labeled tuples for better documentation and tooling support:

type KeyValuePairNamed = [key: string, value: string] // add `key` and `value` labels
const [key, val]: KeyValuePairNamed = ["key", "val"] // array destructuring for convenience

Working playground example

You can use ng-value-true to tell angular that your ng-model is a string.

I could only get ng-true-value working if I added the extra quotes like so (as shown in the official Angular docs - https://docs.angularjs.org/api/ng/input/input%5Bcheckbox%5D)

ng-true-value="'1'"

(See update at end of answer.)

You can get a NodeList of all of the input elements via getElementsByTagName (DOM specification, MDC, MSDN), then simply loop through it:

var inputs, index;

inputs = document.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
    // deal with inputs[index] element.
}

There I've used it on the document, which will search the entire document. It also exists on individual elements (DOM specification), allowing you to search only their descendants rather than the whole document, e.g.:

var container, inputs, index;

// Get the container element
container = document.getElementById('container');

// Find its child `input` elements
inputs = container.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
    // deal with inputs[index] element.
}

...but you've said you don't want to use the parent form, so the first example is more applicable to your question (the second is just there for completeness, in case someone else finding this answer needs to know).

Update: getElementsByTagName is an absolutely fine way to do the above, but what if you want to do something slightly more complicated, like just finding all of the checkboxes instead of all of the input elements?

That's where the useful querySelectorAll comes in: It lets us get a list of elements that match any CSS selector we want. So for our checkboxes example:

var checkboxes = document.querySelectorAll("input[type=checkbox]");

You can also use it at the element level. For instance, if we have a div element in our element variable, we can find all of the spans with the class foo that are inside that div like this:

var fooSpans = element.querySelectorAll("span.foo");

querySelectorAll and its cousin querySelector (which just finds the first matching element instead of giving you a list) are supported by all modern browsers, and also IE8.

You can cast your iterable to a list then use .size() on it.

Lists.newArrayList(iterable).size();

For the sake of clarity, the above method will require the following import:

import com.google.common.collect.Lists;

There are more (many) ways to Rome:

//=>considering predQuery[preId] is undefined:
predQuery[preId] === undefined; //=> true
undefined === predQuery[preId] //=> true
predQuery[preId] || 'it\'s unbelievable!' //=> it's unbelievable
var isdef = predQuery[preId] ? predQuery[preId] : null //=> isdef = null

cheers!

Also, there's the handy little "increase indent" and "decrease indent" buttons. If you highlight a block of code and click those buttons the entire block will indent.

Package name is the reversed domain name, it is a unique name for each application on Playstore. You can't upload two apps with the same package name. You can check package name of the app from playstore url

https://play.google.com/store/apps/details?id=package_name

so you can easily check on playstore that this package name is in used by some other app or not before uploading it.

You probably need more blur and a little less spread.

box-shadow: -10px 0px 10px 1px #aaaaaa;

i just had the same problems - have been testing a lot of different stuff. but it just wouldn't work. then i checked the tutorial examples on jQuery.com again and found out:

your jQuery script needs to be after the elements you are referring to !

so your script needs to be after the html-code you want to access!

seems like jQuery can't access it otherwise.

Upcasting and downcasting are important part of Java, which allow us to build complicated programs using simple syntax, and gives us great advantages, like Polymorphism or grouping different objects. Java permits an object of a subclass type to be treated as an object of any superclass type. This is called upcasting. Upcasting is done automatically, while downcasting must be manually done by the programmer, and i'm going to give my best to explain why is that so.

Upcasting and downcasting are NOT like casting primitives from one to other, and i believe that's what causes a lot of confusion, when programmer starts to learn casting objects.

Polymorphism: All methods in java are virtual by default. That means that any method can be overridden when used in inheritance, unless that method is declared as final or static.

You can see the example below how getType(); works according to the object(Dog,Pet,Police Dog) type.

Assume you have three dogs

1. Dog - This is the super Class.

2. Pet Dog - Pet Dog extends Dog.

3. Police Dog - Police Dog extends Pet Dog.

   public class Dog{ 
      public String getType () {
         System.out.println("NormalDog");
         return "NormalDog";
      }
    }
   
   /**
    * Pet Dog has an extra method dogName()
    */   
   public class PetDog extends Dog{ 
      public String getType () {
         System.out.println("PetDog");
         return "PetDog";
      }
      public String dogName () {
         System.out.println("I don't have Name !!");
         return "NO Name";
      }
    }
   
   /**
    * Police Dog has an extra method secretId()
    */
   public class PoliceDog extends PetDog{
   
    public String secretId() {
       System.out.println("ID");
       return "ID";
    }
   
    public String getType () {
        System.out.println("I am a Police Dog");
        return "Police Dog";
    }
   }
   

Polymorphism : All methods in java are virtual by default. That means that any method can be overridden when used in inheritance, unless that method is declared as final or static.(Explanation Belongs to Virtual Tables Concept)

Virtual Table / Dispatch Table : An object's dispatch table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's dispatch table. The dispatch table is the same for all objects belonging to the same class, and is therefore typically shared between them.

public static void main (String[] args) {
      /**
       * Creating the different objects with super class Reference
       */
     Dog obj1 = new Dog();
`         /**
           *  Object of Pet Dog is created with Dog Reference since                
           *  Upcasting is done automatically for us we don't have to worry about it 
           *  
           */
     Dog obj2 = new PetDog();
`         /**
           *  Object of Police Dog is created with Dog Reference since                
           *  Upcasting is done automatically for us we don't have to worry       
           *  about it here even though we are extending PoliceDog with PetDog 
           *  since PetDog is extending Dog Java automatically upcast for us 
           */
      Dog obj3 = new PoliceDog();
}



 obj1.getType();

Prints Normal Dog

  obj2.getType();

Prints Pet Dog

 obj3.getType();

Prints Police Dog

Downcasting need to be done by the programmer manually

When you try to invoke the secretID(); method on obj3 which is PoliceDog object but referenced to Dog which is a super class in the hierarchy it throws error since obj3 don't have access to secretId() method.In order to invoke that method you need to Downcast that obj3 manually to PoliceDog

  ( (PoliceDog)obj3).secretID();

which prints ID

In the similar way to invoke the dogName();method in PetDog class you need to downcast obj2 to PetDog since obj2 is referenced to Dog and don't have access to dogName(); method

  ( (PetDog)obj2).dogName();

Why is that so, that upcasting is automatical, but downcasting must be manual? Well, you see, upcasting can never fail. But if you have a group of different Dogs and want to downcast them all to a to their types, then there's a chance, that some of these Dogs are actually of different types i.e., PetDog, PoliceDog, and process fails, by throwing ClassCastException.

This is the reason you need to downcast your objects manually if you have referenced your objects to the super class type.

Note: Here by referencing means you are not changing the memory address of your ojects when you downcast it it still remains same you are just grouping them to particular type in this case Dog

Mongo sends the complete document as a callbackobject so you can simply get it from there only.

for example

collection.save(function(err,room){
  var newRoomId = room._id;
  });

I have always enjoyed the syntax of this style:

a = [1, 2, 3, 4]
a.each_with_index.map { |el, index| el + index }
# => [1, 3, 5, 7]

Invoking each_with_index gets you an enumerator you can easily map over with your index available.

Install npm package

npm install material-design-icons --save

Put css file path to styles.css file

@import "../node_modules/material-design-icons-iconfont/dist/material-design-icons.css";

You might need to Deserialize your anonymous JSON type from the request body.

var jsonBody = HttpContext.Request.Content.ReadAsStringAsync().Result;
ScoreInputModel myDeserializedClass = JsonConvert.DeserializeObject<ScoreInputModel>(jsonBody);

I've also seen

x <- {}

Now you can concatenate or bind a vector of any dimension to x

rbind(x, 1:10)
cbind(x, 1:10)
c(x, 10)

This is an Android 8 update.

In earlier version of Android, to LoadLibrary native shared libraries (for access via JNI for example) I hard-wired my native code to iterate through a range of potential directory paths for the lib folder, based on the various apk installation/upgrade algorithms:

/data/data/<PackageName>/lib
/data/app-lib/<PackageName>-1/lib
/data/app-lib/<PackageName>-2/lib
/data/app/<PackageName>-1/lib
/data/app/<PackageName>-2/lib

This approach is hokey and will not work for Android 8; from https://developer.android.com/about/versions/oreo/android-8.0-changes.html you'll see that as part of their "Security" changes you now need to use sourceDir:

"You can no longer assume that APKs reside in directories whose names end in -1 or -2. Apps should use sourceDir to get the directory, and not rely on the directory format directly."

Correction, sourceDir is not the way to find your native shared libraries; use something like. Tested for Android 4.4.4 --> 8.0

// Return Full path to the directory where native JNI libraries are stored.
private static String getNativeLibraryDir(Context context) {
    ApplicationInfo appInfo = context.getApplicationInfo();
    return appInfo.nativeLibraryDir;
}

You can use Git rebasing. For example, if you want to modify back to commit bbc643cd, run

$ git rebase bbc643cd^ --interactive

In the default editor, modify 'pick' to 'edit' in the line whose commit you want to modify. Make your changes and then stage them with

$ git add <filepattern>

Now you can use

$ git commit --amend

to modify the commit, and after that

$ git rebase --continue

to return back to the previous head commit.

To solve the problem of not being able to start mongodb on ubuntu 16.04 1) look at mongodb log file

2) we find that the error is due to "Failed to unlink socket file /tmp/mongodb-27017"

3) Look at the permission of file /tmp/mongdb-27017.lock and find that the owner is root instead of mongodb

4) Delete the /tmp/mongodb-27017.sock file manually and use the command "sudo chown mongodb:mongodb /tmp/mongodb*"

5) Start the service with systemcl and use netstat to check whther mongdob has been started on port 27017

For the Background, make sure you have imported java.awt.Color into your package.

In your main method, i.e. public static void main(String[] args), call the already imported method:

JLabel name_of_your_label=new JLabel("the title of your label");
name_of_your_label.setBackground(Color.the_color_you_wish);
name_of_your_label.setOpaque(true);

NB: Setting opaque will affect its visibility. Remember the case sensitivity in Java.

This solution fixed my problem while replacing br tag to '\n' .

alert(content.replace(/<br\/\>/g,'\n'));

You can use setdefault.

for line in list:  
    d.setdefault(year, []).append(value)

This works because setdefault returns the list as well as setting it on the dictionary, and because a list is mutable, appending to the version returned by setdefault is the same as appending it to the version inside the dictionary itself. If that makes any sense.

Definitely don't do this, but it is an option if ... I can't think of a valid reason.

<style name="CustomActivityThemeNoActionBar" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

Then in your AndroidManifest.xml file add the below code in the required activity

<activity
        android:name="com.newbelievers.android.NBMenu"
        android:label="@string/title_activity_nbmenu"
        android:theme="@style/CustomActivityThemeNoActionBar">
</activity>

To use await/async you need methods that return promises. The core API functions don't do that without wrappers like promisify:

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

// Convert fs.readFile into Promise version of same    
const readFile = util.promisify(fs.readFile);

function getStuff() {
  return readFile('test');
}

// Can't use `await` outside of an async function so you need to chain
// with then()
getStuff().then(data => {
  console.log(data);
})

As a note, readFileSync does not take a callback, it returns the data or throws an exception. You're not getting the value you want because that function you supply is ignored and you're not capturing the actual return value.

Another way to check is to inline the function, so that the condition will be checked on every render (every props and state change)

const isDisabled = () => 
  // condition check

This works:

<button
  type="button"
  disabled={this.isDisabled()}
>
  Let Me In
</button>

but this will not work:

<button
   type="button"
   disabled={this.isDisabled}
>
  Let Me In
</button>

Input. We will start with the text of the input shown in the question since the question did not provide the csv input:

Lines <- "Dates   Bajaj_close Hero_close
3/14/2013   1854.8  1669.1
3/15/2013   1850.3  1684.45
3/18/2013   1812.1  1690.5
3/19/2013   1835.9  1645.6
3/20/2013   1840    1651.15
3/21/2013   1755.3  1623.3
3/22/2013   1820.65 1659.6
3/25/2013   1802.5  1617.7
3/26/2013   1801.25 1571.85
3/28/2013   1799.55 1542"

zoo. "ts" class series normally do not represent date indexes but we can create a zoo series that does (see zoo package):

library(zoo)
z <- read.zoo(text = Lines, header = TRUE, format = "%m/%d/%Y")

Alternately, if you have already read this into a data frame DF then it could be converted to zoo as shown on the second line below:

DF <- read.table(text = Lines, header = TRUE)
z <- read.zoo(DF, format = "%m/%d/%Y")

In either case above z ia a zoo series with a "Date" class time index. One could also create the zoo series, zz, which uses 1, 2, 3, ... as the time index:

zz <- z
time(zz) <- seq_along(time(zz))

ts. Either of these could be converted to a "ts" class series:

as.ts(z)
as.ts(zz)

The first has a time index which is the number of days since the Epoch (January 1, 1970) and will have NAs for missing days and the second will have 1, 2, 3, ... as the time index and no NAs.

Monthly series. Typically "ts" series are used for monthly, quarterly or yearly series. Thus if we were to aggregate the input into months we could reasonably represent it as a "ts" series:

z.m <- as.zooreg(aggregate(z, as.yearmon, mean), freq = 12)
as.ts(z.m)

Easiest way I can think of:

def which(program):
    import os
    def is_exe(fpath):
        return os.path.isfile(fpath) and os.access(fpath, os.X_OK)

    fpath, fname = os.path.split(program)
    if fpath:
        if is_exe(program):
            return program
    else:
        for path in os.environ["PATH"].split(os.pathsep):
            exe_file = os.path.join(path, program)
            if is_exe(exe_file):
                return exe_file

    return None

Edit: Updated code sample to include logic for handling case where provided argument is already a full path to the executable, i.e. "which /bin/ls". This mimics the behavior of the UNIX 'which' command.

Edit: Updated to use os.path.isfile() instead of os.path.exists() per comments.

Edit: path.strip('"') seems like the wrong thing to do here. Neither Windows nor POSIX appear to encourage quoted PATH items.

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..

You will get all the class in below array

event.target.classList

This is not difficult to achieve, but you need to use the javascript onmouseover function. Pseudoscript:

<div class="section ">

<div class="image"><img src="myImage.jpg" onmouseover=".layer {border: 1px solid black;} .image {border: 1px solid black;}" /></div>

<div class="layer">Lorem Ipsum</div>

</div>

Use your own colors. You can also reference javascript functions in the mouseover command.

I often need to run an X command on a server that is running many X servers, so the ps based answers do not work. Naturally, $DISPLAY has to be set appropriately. To check that that is valid, use xset q in some fragment like:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

EDIT

Some people find that xset can pause for a annoying amount of time before deciding that $DISPLAY is not pointing at a valid X server (often when tcp/ip is the transport). The fix of course is to use timeout to keep the pause amenable, 1 second say.

if ! timeout 1s xset q &>/dev/null; then
    ?

Implement custom adapter for your class:

public class MyClassAdapter extends ArrayAdapter<MyClass> {

    private static class ViewHolder {
        private TextView itemView;
    }

    public MyClassAdapter(Context context, int textViewResourceId, ArrayList<MyClass> items) {
        super(context, textViewResourceId, items);
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = LayoutInflater.from(this.getContext())
            .inflate(R.layout.listview_association, parent, false);

            viewHolder = new ViewHolder();
            viewHolder.itemView = (TextView) convertView.findViewById(R.id.ItemView);

            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        MyClass item = getItem(position);
        if (item!= null) {
            // My layout has only one TextView
                // do whatever you want with your string and long
            viewHolder.itemView.setText(String.format("%s %d", item.reason, item.long_val));
        }

        return convertView;
    }
}

For those not very familiar with the Android framework, this is explained in better detail here: https://github.com/codepath/android_guides/wiki/Using-an-ArrayAdapter-with-ListView.

From Tomcat documentation, For blocking I/O (BIO), the default value of maxConnections is the value of maxThreads unless Executor (thread pool) is used in which case, the value of 'maxThreads' from Executor will be used instead. For Non-blocking IO, it doesn't seem to be dependent on maxThreads.

Already very good solution came. I'm just puting the total code so that a newbie get total help

<?php
extract($_GET); //you can send some parameter by query variable. I have sent table name in *table* variable

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$table.csv");
header("Pragma: no-cache");
header("Expires: 0");

require_once("includes/functions.php"); //necessary mysql connection functions here

//first of all I'll get the column name to put title of csv file.
$query = "SHOW columns FROM $table";
$headers = mysql_query($query) or die(mysql_error());
$csv_head = array();
while ($row = mysql_fetch_array($headers, MYSQL_ASSOC))
{
    $csv_head[] =  $row['Field'];
}
echo implode(",", $csv_head)."\n";

//now I'll bring the data.
$query = "SELECT * FROM $table";
$select_c = mysql_query($query) or die(mysql_error()); 

while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
    foreach ($row as $key => $value) {
            //there may be separator (here I have used comma) inside data. So need to put double quote around such data.
        if(strpos($value, ',') !== false || strpos($value, '"') !== false || strpos($value, "\n") !== false) {
            $row[$key] = '"' . str_replace('"', '""', $value) . '"';
        }
    }
    echo implode(",", $row)."\n";
}

?>

I have saved this code in csv-download.php

Now see how I have used this data to download csv file

<a href="csv-download.php?table=tbl_vfm"><img title="Download as Excel" src="images/Excel-logo.gif" alt="Download as Excel" /><a/>

So when I have clicked the link it download the file without taking me to csv-download.php page on browser.

I collected and tested discussed solutions:

Windows10 Prof x64:

* FireFox v.56.0 x32 
* Opera v.49.0
* Google Chrome v.61.0.3163.100 x64-bit

macOs X Serra v.10.12.6 Mac mini (Mid 2010):

* Safari v.10.1.2(12603.3.8)
* FireFox v.57.0 Quantum
* Opera v49.0

Semi (still micro fat in Safari) solved fatty fonts:

text-transform: none; // mac ff fix
-webkit-font-smoothing: antialiased; // safari mac nicer
-moz-osx-font-smoothing: grayscale; // fix fatty ff on mac

Have no visual effect

line-height: 1;
text-rendering: optimizeLegibility; 
speak: none;
font-style: normal;
font-variant: normal;

Wrong visual effect:

-webkit-font-smoothing: subpixel-antialiased !important; //more fatty in safari
text-rendering: geometricPrecision !important; //more fatty in safari

do not forget to set !important when testing or be sure that your style is not overridden

re the edit: "Also i need a way to do the reverse If the float is a negative, make it a positive"

$number = -$number;

changes the number to its opposite.

Built-in toLocaleDateString() does the job, but it will remove the leading 0s for the day and month, so we will get something like "1/9/1970", which is not perfect in my opinion. To get a proper format MM/DD/YYYY we can use something like:

new Date(dateString).toLocaleDateString('en-US', {
  day: '2-digit',
  month: '2-digit',
  year: 'numeric',
})

>>> print "%r, %r" % (True, False)
True, False

This is not specific to boolean values - %r calls the __repr__ method on the argument. %s (for str) should also work.

Easy way to parse the xml is to use the LINQ to XML

for example you have the following xml file

<library>
    <track id="1" genre="Rap" time="3:24">
        <name>Who We Be RMX (feat. 2Pac)</name>
        <artist>DMX</artist>
        <album>The Dogz Mixtape: Who's Next?!</album>
    </track>
    <track id="2" genre="Rap" time="5:06">
        <name>Angel (ft. Regina Bell)</name>
        <artist>DMX</artist>
        <album>...And Then There Was X</album>
    </track>
    <track id="3" genre="Break Beat" time="6:16">
        <name>Dreaming Your Dreams</name>
        <artist>Hybrid</artist>
        <album>Wide Angle</album>
    </track>
    <track id="4" genre="Break Beat" time="9:38">
        <name>Finished Symphony</name>
        <artist>Hybrid</artist>
        <album>Wide Angle</album>
    </track>
<library>

For reading this file, you can use the following code:

public void Read(string  fileName)
{
    XDocument doc = XDocument.Load(fileName);

    foreach (XElement el in doc.Root.Elements())
    {
        Console.WriteLine("{0} {1}", el.Name, el.Attribute("id").Value);
        Console.WriteLine("  Attributes:");
        foreach (XAttribute attr in el.Attributes())
            Console.WriteLine("    {0}", attr);
        Console.WriteLine("  Elements:");

        foreach (XElement element in el.Elements())
            Console.WriteLine("    {0}: {1}", element.Name, element.Value);
    }
}

You need to slightly modify your compare function and use functools.cmp_to_key to pass it to sorted. Example code:

import functools

lst = [list(range(i, i+5)) for i in range(5, 1, -1)]

def fitness(item):
    return item[0]+item[1]+item[2]+item[3]+item[4]
def compare(item1, item2):
    return fitness(item1) - fitness(item2)

sorted(lst, key=functools.cmp_to_key(compare))

Output:

[[2, 3, 4, 5, 6], [3, 4, 5, 6, 7], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]]

Works :)

You can wrap the following in a DIV:

<div class="your-class">

  <label for="First_Name">First Name:</label>
  <input name="first_name" id="First_Name" type="text" />
  <label for="Name">Last Name:</label>
  <input name="last_name" id="Last_Name" type="text" /> 

</div>

Give each input float:left in your CSS:

.your-class input{
  float:left;
}

example only

You might have to adjust margins.

Remember to apply clear:left or both to whatever comes after ".your-class"

use HTML instead of javascript

the cause could be a variety of reasons. It might not show up in the log files. I had the case where the log showed Apache started, then all threads shut down, and absolutely no explanation why. Here's a tip for solving this problem everybody seems to have missed. The log file should show the full command line used to start apache, something like:

httpd -d C:/wamp/bin/apache/apache2.4.9

Do this: open a cmd window, cd to the apache bin directory, and run the command manually:

c:\> cd C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\apache\apache2.4.9\bin> httpd -d C:/wamp/bin/apache/apache2.4.9

It blurted out the error stright away; problem solved in 5 minutes:

AH00526: Syntax error on line 609 of C:/wamp/bin/apache/apache2.4.9/conf/httpd.conf:
CustomLog takes two or three arguments, a file name, a custom log format string or format name, and an optional "env=" or "expr=" clause (see docs)

this happened due to a syntax error I put in 'httpd.conf' while trying to make my wampserver multi-homed. But why didn't the apache people write this in the log file?

just add android:gravity="right" in your Liner Layout.

try this.

UPDATE `database_name`.`table_name` SET `column_name`='value' WHERE `id`='1';

I recommend something like this:

    public class MyMap {

      Map<Object, V> map = new HashMap<Object, V>();


      public V put(K1 key,V value){
        return map.put(key, value);
      }

      public V put(K2 key,V value){
        return map.put(key, value);
      }

      public V get(K1 key){    
        return map.get(key);
      }

      public V get(K2 key){    
        return map.get(key);
      }

      //Same for conatains

    }

Then you can use it like:
myMap.put(k1,value) or myMap.put(k2,value)

Advantages: It is simple, enforces type safety, and doesn't store repeated data (as the two maps solutions do, though still store duplicate values).
Drawbacks: Not generic.

I ran into the same issue and I solved it by including my username and password in the repo url:

git clone https://myusername:[email protected]/path_to/myRepo.git

I had to do something like this on a version of linux that didn't have the right options compiled into wget. This example is for downloading the memory analysis tool 'guppy'. I'm not sure if it's important or not, but I kept the target file's name the same as the url target name...

Here's what I came up with:

python -c "import requests; r = requests.get('https://pypi.python.org/packages/source/g/guppy/guppy-0.1.10.tar.gz') ; open('guppy-0.1.10.tar.gz' , 'wb').write(r.content)"

That's the one-liner, here's it a little more readable:

import requests
fname = 'guppy-0.1.10.tar.gz'
url = 'https://pypi.python.org/packages/source/g/guppy/' + fname
r = requests.get(url)
open(fname , 'wb').write(r.content)

This worked for downloading a tarball. I was able to extract the package and download it after downloading.

EDIT:

To address a question, here is an implementation with a progress bar printed to STDOUT. There is probably a more portable way to do this without the clint package, but this was tested on my machine and works fine:

#!/usr/bin/env python

from clint.textui import progress
import requests

fname = 'guppy-0.1.10.tar.gz'
url = 'https://pypi.python.org/packages/source/g/guppy/' + fname

r = requests.get(url, stream=True)
with open(fname, 'wb') as f:
    total_length = int(r.headers.get('content-length'))
    for chunk in progress.bar(r.iter_content(chunk_size=1024), expected_size=(total_length/1024) + 1): 
        if chunk:
            f.write(chunk)
            f.flush()

If you’re using python 3+ this may also occur if you’re using private variables that start with double underscore, e.g., self.__yourvariable. Just something to take note of for some of you who may run into this issue.

The ideas provided above are good. For fast access (in case you would like to make a real time application) you could try the following:

//suppose you read an image from a file that is gray scale
Mat image = imread("Your path", CV_8UC1);
//...do some processing
uint8_t *myData = image.data;
int width = image.cols;
int height = image.rows;
int _stride = image.step;//in case cols != strides
for(int i = 0; i < height; i++)
{
    for(int j = 0; j < width; j++)
    {
        uint8_t val = myData[ i * _stride + j];
        //do whatever you want with your value
    }
}

Pointer access is much faster than the Mat.at<> accessing. Hope it helps!

jQuery.fn.outerHTML = function() {
    return $(this).clone().wrap('<div>').parent().html();
};
$('input#password').replaceWith($('input.password').outerHTML().replace(/text/g,'password'));

Use:

/* @var $objs Test[] */
foreach ($objs as $obj) {
    // Typehinting will occur after typing $obj->
}

when typehinting inline variables, and

class A {
    /** @var Test[] */
    private $items;
}

for class properties.

Previous answer from '09 when PHPDoc (and IDEs like Zend Studio and Netbeans) didn't have that option:

The best you can do is say,

foreach ($Objs as $Obj)
{
    /* @var $Obj Test */
    // You should be able to get hinting after the preceding line if you type $Obj->
}

I do that a lot in Zend Studio. Don't know about other editors, but it ought to work.

The problem is you're not doing anything with the result of replace. In Python strings are immutable so anything that manipulates a string returns a new string instead of modifying the original string.

line[8] = line[8].replace(letter, "")

Just print out the embed after construction graph (ops) without running:

import tensorflow as tf

...

train_dataset = tf.placeholder(tf.int32, shape=[128, 2])
embeddings = tf.Variable(
    tf.random_uniform([50000, 64], -1.0, 1.0))
embed = tf.nn.embedding_lookup(embeddings, train_dataset)
print (embed)

This will show the shape of the embed tensor:

Tensor("embedding_lookup:0", shape=(128, 2, 64), dtype=float32)

Usually, it's good to check shapes of all tensors before training your models.

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

import {Observable} from 'rxjs/Rx';

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

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

like this -

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

Update

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

You can do it with drop_duplicates as you wanted

# initialisation
d = pd.DataFrame({'A' : [1,1,2,3,3], 'B' : [2,2,7,4,4],  'C' : [1,4,1,0,8]})

d = d.sort_values("C", ascending=False)
d = d.drop_duplicates(["A","B"])

If it's important to get the same order

d = d.sort_index()

I prefer to use WebClient, it seems to handle SSL transparently:

There’s a gem like quiet_assets that will silence these errors in your logs if, like me, you didn’t want to have to add these files to your Rails app:

In my projects, we usually call server side method like this:

in JavaScript:

document.getElementById("UploadButton").click();

Server side control:

<asp:Button runat="server" ID="UploadButton" Text="" style="display:none;" OnClick="UploadButton_Click" />

C#:

protected void Upload_Click(object sender, EventArgs e)
{

}

You can replace nan with None in your numpy array:

>>> x = np.array([1, np.nan, 3])
>>> y = np.where(np.isnan(x), None, x)
>>> print y
[1.0 None 3.0]
>>> print type(y[1])
<type 'NoneType'>

Use doc.childNodes to iterate through each span, and then filter the one whose className equals 4:

var doc = document.getElementById("test");
var notes = null;
for (var i = 0; i < doc.childNodes.length; i++) {
    if (doc.childNodes[i].className == "4") {
      notes = doc.childNodes[i];
      break;
    }        
}

?

After trying examples (PHP 5.3.5), I found that in both cases of defining functions you can't use $this operator to work on class functions. So I couldn't find a difference in them yet. :(

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.

MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx

If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed.

The variable name is also wrong because Cancel is called on CancellationTokenSource not the token itself and the source changes state of each token it manages.

Some refinements to answer above. To remove more than one char you add multiple question marks. For example, to remove last two chars from variable $SRC_IP_MSG, you can use:

SRC_IP_MSG=${SRC_IP_MSG%??}

The only thing you can do is obfuscate your code to make it more difficult to read. No matter what you do, if you want the javascript to execute in their browser they'll have to have the code.

By the way, if you need to add other characters such as "(" or ")" because the column may be used as "UPPER(bqr)", then those options can be added to the lists of before and after characters.

(\s|\(|\.|,|^)bqr(\s|,|\)|$)

The javascript library sugar.js (http://sugarjs.com/) has functions to format dates

Example:

There's a funny named method/constant/whatever in each version of Android.

The only practical use I ever saw was in the Last Call for Google I/O Contest where they asked what it was for a particular version, to see if contestants read the API diff report for each release. The contest had programming problems too, but generally some trivia that could be graded automatically first to get the number of submissions down to reasonable amounts that would be easier to check.

The criterion to satisfy for providing the new shape is that 'The new shape should be compatible with the original shape'

numpy allow us to give one of new shape parameter as -1 (eg: (2,-1) or (-1,3) but not (-1, -1)). It simply means that it is an unknown dimension and we want numpy to figure it out. And numpy will figure this by looking at the 'length of the array and remaining dimensions' and making sure it satisfies the above mentioned criteria

Now see the example.

z = np.array([[1, 2, 3, 4],
         [5, 6, 7, 8],
         [9, 10, 11, 12]])
z.shape
(3, 4)

Now trying to reshape with (-1) . Result new shape is (12,) and is compatible with original shape (3,4)

z.reshape(-1)
array([ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12])

Now trying to reshape with (-1, 1) . We have provided column as 1 but rows as unknown . So we get result new shape as (12, 1).again compatible with original shape(3,4)

z.reshape(-1,1)
array([[ 1],
   [ 2],
   [ 3],
   [ 4],
   [ 5],
   [ 6],
   [ 7],
   [ 8],
   [ 9],
   [10],
   [11],
   [12]])

The above is consistent with numpy advice/error message, to use reshape(-1,1) for a single feature; i.e. single column

Reshape your data using array.reshape(-1, 1) if your data has a single feature

New shape as (-1, 2). row unknown, column 2. we get result new shape as (6, 2)

z.reshape(-1, 2)
array([[ 1,  2],
   [ 3,  4],
   [ 5,  6],
   [ 7,  8],
   [ 9, 10],
   [11, 12]])

Now trying to keep column as unknown. New shape as (1,-1). i.e, row is 1, column unknown. we get result new shape as (1, 12)

z.reshape(1,-1)
array([[ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12]])

The above is consistent with numpy advice/error message, to use reshape(1,-1) for a single sample; i.e. single row

Reshape your data using array.reshape(1, -1) if it contains a single sample

New shape (2, -1). Row 2, column unknown. we get result new shape as (2,6)

z.reshape(2, -1)
array([[ 1,  2,  3,  4,  5,  6],
   [ 7,  8,  9, 10, 11, 12]])

New shape as (3, -1). Row 3, column unknown. we get result new shape as (3,4)

z.reshape(3, -1)
array([[ 1,  2,  3,  4],
   [ 5,  6,  7,  8],
   [ 9, 10, 11, 12]])

And finally, if we try to provide both dimension as unknown i.e new shape as (-1,-1). It will throw an error

z.reshape(-1, -1)
ValueError: can only specify one unknown dimension

There's a far more simpler solution to tackle this.

The reason why you get ValueError: Index contains duplicate entries, cannot reshape is because, once you unstack "Location", then the remaining index columns "id" and "date" combinations are no longer unique.

You can avoid this by retaining the default index column (row #) and while setting the index using "id", "date" and "location", add it in "append" mode instead of the default overwrite mode.

So use,

e.set_index(['id', 'date', 'location'], append=True)

Once this is done, your index columns will still have the default index along with the set indexes. And unstack will work.

Let me know how it works out.

Maximum value of any unsigned integral type:

• ((t)~(t)0) // Generic expression that would work in almost all circumstances.

• (~(t)0) // If you know your type t have equal or larger size than unsigned int. (This cast forces type promotion.)

• ((t)~0U) // If you know your type t have smaller size than unsigned int. (This cast demotes type after the unsigned int-type expression ~0U is evaluated.)

Maximum value of any signed integral type:

• If you have an unsigned variant of type t, ((t)(((unsigned t)~(unsigned t)0)>>1)) would give you the fastest result you need.

• Otherwise, use this (thanks to @vinc17 for suggestion): (((1ULL<<(sizeof(t)*CHAR_BIT-2))-1)*2+1)

Minimum value of any signed integral type:

You have to know the signed number representation of your machine. Most machines use 2's complement, and so -(((1ULL<<(sizeof(t)*CHAR_BIT-2))-1)*2+1)-1 will work for you.

To detect whether your machine uses 2's complement, detect whether (~(t)0U) and (t)(-1) represent the same thing.

So, combined with above:

(-(((1ULL<<(sizeof(t)*CHAR_BIT-2))-1)*2+1)-(((~(t)0U)==(t)(-1)))

will give you the minimum value of any signed integral type.

As an example: Maximum value of size_t (a.k.a. the SIZE_MAX macro) can be defined as (~(size_t)0). Linux kernel source code define SIZE_MAX macro this way.

One caveat though: All of these expressions use either type casting or sizeof operator and so none of these would work in preprocessor conditionals (#if ... #elif ... #endif and like).

(Answer updated for incorpoating suggestions from @chux and @vinc17. Thank you both.)

On macOS, none of the answers worked for me. I discovered that was due to differences in how sed works on macOS and other BSD systems compared to GNU.

In particular BSD sed takes the -i option but requires a suffix for the backup (but an empty suffix is permitted)

grep version from this answer.

grep -rl 'foo' ./ | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

find version from this answer.

find . \( ! -regex '.*/\..*' \) -type f | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

Don't omit the Regex to ignore . folders if you're in a Git repo. I realized that the hard way!

That LC_ALL=C option is to avoid getting sed: RE error: illegal byte sequence if sed finds a byte sequence that is not a valid UTF-8 character. That's another difference between BSD and GNU. Depending on the kind of files you are dealing with, you may not need it.

For some reason that is not clear to me, the grep version found more occurrences than the find one, which is why I recommend to use grep.

I use codeigniter 3+. I had the same problem and in my case I changed model file name starting from uppser case.

Save yourself some pain...

using System.Linq;

int[] ints = new [] { 10, 20, 10, 34, 113 };

List<int> lst = ints.OfType<int>().ToList(); // this isn't going to be fast.

Can also just...

List<int> lst = new List<int> { 10, 20, 10, 34, 113 };

or...

List<int> lst = new List<int>();
lst.Add(10);
lst.Add(20);
lst.Add(10);
lst.Add(34);
lst.Add(113);

or...

List<int> lst = new List<int>(new int[] { 10, 20, 10, 34, 113 });

or...

var lst = new List<int>();
lst.AddRange(new int[] { 10, 20, 10, 34, 113 });

It's a hex number and is 16 decimal.

One way to make sure it is correct is by using character instead of ascii code.

if ((a >= 65) && (a <= 90))

what you want is to lower a case. it's better to use something like if (a >= 'A' && a <= 'Z') . You don't have to remind all ascii code :)

Swift 2.0 version:

//Get image and set it's size
let image = UIImage(named: "imageNameWithHeart")
let newSize = CGSize(width: 10, height: 10)

//Resize image
UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
image?.drawInRect(CGRectMake(0, 0, newSize.width, newSize.height))
let imageResized = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

//Create attachment text with image
var attachment = NSTextAttachment()
attachment.image = imageResized
var attachmentString = NSAttributedString(attachment: attachment)
var myString = NSMutableAttributedString(string: "I love swift ")
myString.appendAttributedString(attachmentString)
myLabel.attributedText = myString

Resolve the route to a URL and navigate the window with Javascript.

        let r = this.$router.resolve({_x000D_
        name: this.$route.name, // put your route information in_x000D_
        params: this.$route.params, // put your route information in_x000D_
        query: this.$route.query // put your route information in_x000D_
      });_x000D_
      window.location.assign(r.href)

This method replaces the URL and causes the page to do a full request (refresh) rather than relying on Vue.router. $router.go does not work the same for me even though it is theoretically supposed to.

$base_dir = __DIR__; // Absolute path to your installation, ex: /var/www/mywebsite
$doc_root = preg_replace("!{$_SERVER['SCRIPT_NAME']}$!", '', $_SERVER['SCRIPT_FILENAME']); # ex: /var/www
$base_url = preg_replace("!^{$doc_root}!", '', $base_dir); # ex: '' or '/mywebsite'
$base_url = str_replace('\\', '/', $base_url);//On Windows
$base_url = str_replace($doc_root, '', $base_url);//On Windows
$protocol = empty($_SERVER['HTTPS']) ? 'http' : 'https';
$port = $_SERVER['SERVER_PORT'];
$disp_port = ($protocol == 'http' && $port == 80 || $protocol == 'https' && $port == 443) ? '' : ":$port";
$domain = $_SERVER['SERVER_NAME'];
$full_url = "$protocol://{$domain}{$disp_port}{$base_url}"; # Ex: 'http://example.com', 'https://example.com/mywebsite', etc.

Setup https://docs.djangoproject.com/en/dev/topics/logging/ and then these error's will echo where you point them. By default they tend to go off in the weeds so I always start off with a good logging setup before anything else.

Here is a really good example for a basic setup: https://ian.pizza/b/2013/04/16/getting-started-with-django-logging-in-5-minutes/

Edit: The new link is moved to: https://github.com/ianalexander/ianalexander/blob/master/content/blog/getting-started-with-django-logging-in-5-minutes.html

Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.setComponent(new ComponentName("package_name","package_name.class_name"));
        intent.putExtra("grace", "Hi");
        startActivity(intent);

You can look for the four underscore in this way:

create table #test
( t varchar(50) );

insert into #test values 
( 'abc_1_2_3_4.gif'),
('zzz_12_3_3_45.gif');

declare @t varchar(50);
declare @t_aux varchar(50);
declare @t1 int;
declare @t2 int;
declare @t3 int;
declare @t4 int;

DECLARE t_cursor CURSOR
    FOR SELECT t FROM #test
OPEN t_cursor
FETCH NEXT FROM t_cursor into @t;?
set @t1 = charindex( '_', @t )
set @t2 = charindex( '_', @t , @t1+1)
set @t3 = charindex( '_', @t , @t2+1)
set @t4 = charindex( '_', @t , @t3+1)

select @t1, @t2, t3, t4

--do a loop to iterate over all table

you can test it here.

Or in this simple way:

select 
  charindex( '_', t ) as first,
  charindex( '_', t, charindex( '_', t ) + 1 ) as second,
  ...
from 
  #test

A quick step-by-step guide how to configure NetBeans default encoding UTF-8. In result NetBeans will create all new files in UTF-8 encoding.

NetBeans default encoding UTF-8 step-by-step guide

• Go to etc folder in NetBeans installation directory

• Edit netbeans.conf file

• Find netbeans_default_options line

• Add -J-Dfile.encoding=UTF-8 inside quotation marks inside that line

  (example: netbeans_default_options="-J-Dfile.encoding=UTF-8")

• Restart NetBeans

You set NetBeans default encoding UTF-8.

Your netbeans_default_options may contain additional parameters inside the quotation marks. In such case, add -J-Dfile.encoding=UTF-8 at the end of the string. Separate it with space from other parameters.

Example:

netbeans_default_options="-J-client -J-Xss128m -J-Xms256m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true -J-Dfile.encoding=UTF-8"

here is link for Further Details

You can simply use .toString().

var result = require('child_process').execSync('rsync -avAXz --info=progress2 "/src" "/dest"').toString();
console.log(result);

This has been tested on Node v8.5.0, I'm not sure about previous versions. According to @etov, it doesn't work on v6.3.1 - I'm not sure about in-between.

Edit: Looking back on this, I've realised that it doesn't actually answer the specific question because it doesn't show the output to you 'live' — only once the command has finished running.

However, I'm leaving this answer here because I know quite a few people come across this question just looking for how to print the result of the command after execution.

@amro's answer translated to Swift 4.0:

tidyr::gather() is the one in tidyverse workflow to turn wide dataframe to long tidy layout, then ggplot could plot multiple serials.

You can use a "quote wall" to separate the formatted string part from the regular string part.

From:

print(f"{Hello} {42}")

to

print("{Hello}"f" {42}")

A clearer example would be

string = 10
print(f"{string} {word}")

Output:

NameError: name 'word' is not defined

Now, add the quote wall like so:

string = 10
print(f"{string}"" {word}")

Output:

10 {word}

If your are not in a session you can just nextval('you_sequence_name') and it's just fine.

Here's a simple and working method I found elsewhere:

string hexString = "7FF";
int hexNumber;
sscanf(hexString.c_str(), "%x", &hexNumber);

Please note that you might prefer using unsigned long integer/long integer, to receive the value. Another note, the c_str() function just converts the std::string to const char* .

So if you have a const char* ready, just go ahead with using that variable name directly, as shown below [I am also showing the usage of the unsigned long variable for a larger hex number. Do not confuse it with the case of having const char* instead of string]:

const char *hexString = "7FFEA5"; //Just to show the conversion of a bigger hex number
unsigned long hexNumber; //In case your hex number is going to be sufficiently big.
sscanf(hexString, "%x", &hexNumber);

This works just perfectly fine (provided you use appropriate data types per your need).

For Apache 2.4.2: I was getting 403: Forbidden continuously when I was trying to access WAMP on my Windows 7 desktop from my iPhone on WiFi. On one blog, I found the solution - add Require all granted after Allow all in the <Directory> section. So this is how my <Directory> section looks like inside <VirtualHost>

<Directory "C:/wamp/www">
    Options Indexes FollowSymLinks MultiViews Includes ExecCGI
    AllowOverride All
    Order Allow,Deny
    Allow from all
    Require all granted
</Directory>

For people wanting a server runnable from within NodeJS script:

You can use expressjs/serve-static which replaces connect.static (which is no longer available as of connect 3):

myapp.js:

var http = require('http');

var finalhandler = require('finalhandler');
var serveStatic = require('serve-static');

var serve = serveStatic("./");

var server = http.createServer(function(req, res) {
  var done = finalhandler(req, res);
  serve(req, res, done);
});

server.listen(8000);

and then from command line:

• $ npm install finalhandler serve-static
• $ node myapp.js

Note: if you are trying to get this information for tables that are in a different SCHEMA use the all_tab_columns view, we have this problem as our Applications use a different SCHEMA for security purposes.

use the following:

EG:

SELECT
    data_length 
FROM
    all_tab_columns 
WHERE
    upper(table_name) = 'MY_TABLE_NAME' AND upper(column_name) = 'MY_COL_NAME'

Since nobody has mentioned it, I'd like to add that Facebook chat is written in Erlang.

If you just want to test a library from the command line, you could do:

cat somelibrary.js mytestfile.js | node

.each() should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map.

var newArray = $(array).map(function(i) {
    return $('#event' + i, response).html();
});

Edit: I removed the adding of the prepended 0 since it is suggested to not use that.

If you must have it use

var newArray = $(array).map(function(i) {
    var number = '' + i;
    if (number.length == 1) {
        number = '0' + number;
    }   
    return $('#event' + number, response).html();
});

Write this is the activity you are in:

Intent intent = new Intent(CurrentActivity.this,NextActivity.class);
intent.putExtras("string_name","string_to_pass");
startActivity(intent);

In the NextActivity.java

Intent getIntent = getIntent();
//call a TextView object to set the string to
TextView text = (TextView)findViewById(R.id.textview_id);
text.setText(getIntent.getStringExtra("string_name"));

This works for me, you can try it.

Source:https://www.c-sharpcorner.com/article/how-to-send-the-data-one-activity-to-another-activity-in-android-application/

<ul id="unOrderedList">
<li value="2">Whatever</li>
.
.



 $('#unOrderedList li').click(function(){
      var value = $(this).attr('value');
     alert(value); 
  });

Your looking for the attribute "value" inside the "li" tag

Whatever algebra you are doing in Excel to create the new column could probably be done more effectively in R.

Please try the following: Read the raw file (before any excel manipulation) into R using read.csv(... stringsAsFactors=FALSE). [If that does not work, please take a look at ?read.table (which read.csv wraps), however there may be some other underlying issue].

For example:

   delim = ","  # or is it "\t" ?
   dec = "."    # or is it "," ?
   myDataFrame <- read.csv("path/to/file.csv", header=TRUE, sep=delim, dec=dec, stringsAsFactors=FALSE)

Then, let's say your numeric columns is column 4

   myDataFrame[, 4]  <- as.numeric(myDataFrame[, 4])  # you can also refer to the column by "itsName"

@user.route('/<user_id>', defaults={'username': default_value})
@user.route('/<user_id>/<username>')
def show(user_id, username):
   #
   pass

This is by far the most general and performant solution; surprised it hasn't been posted yet.

import numpy as np

def unique_count(a):
    unique, inverse = np.unique(a, return_inverse=True)
    count = np.zeros(len(unique), np.int)
    np.add.at(count, inverse, 1)
    return np.vstack(( unique, count)).T

print unique_count(np.random.randint(-10,10,100))

Unlike the currently accepted answer, it works on any datatype that is sortable (not just positive ints), and it has optimal performance; the only significant expense is in the sorting done by np.unique.

Or if you need inline then you can do this:

<a href="#" ng-click="show = !show; $event.preventDefault()">Click to show</a>

If you want to center the th of all tables:
table th{ text-align: center; }

If you only want to center the th of a table with a determined id:
table#tableId th{ text-align: center; }

I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/

I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):

virtualenv --python=/usr/bin/python2.7 my_venv

Once I activated it, I run pip install unirest successfully.

Make sure to use WEBP as your media format to save more space with same quality:

fun saveImage(context: Context, bitmap: Bitmap, name: String): String {
        context.openFileOutput(name, Context.MODE_PRIVATE).use { fos ->
            bitmap.compress(Bitmap.CompressFormat.WEBP, 25, fos)
        }
    return context.filesDir.absolutePath
 }

For elementwise multiplication of matrix objects, you can use numpy.multiply:

import numpy as np
a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])
np.multiply(a,b)

Result

array([[ 5, 12],
       [21, 32]])

However, you should really use array instead of matrix. matrix objects have all sorts of horrible incompatibilities with regular ndarrays. With ndarrays, you can just use * for elementwise multiplication:

a * b

If you're on Python 3.5+, you don't even lose the ability to perform matrix multiplication with an operator, because @ does matrix multiplication now:

a @ b  # matrix multiplication

I have been able to work around this bug by setting a unique name attribute on the iframe - for whatever reason, this seems to bust the cache. You can use whatever dynamic data you have as the name attribute - or simply the current ms or ns time in whatever templating language you're using. This is a nicer solution than those above because it does not directly require JS.

In my particular case, the iframe is being built via JS (but you could do the same via PHP, Ruby, whatever), so I simply use Date.now():

return '<iframe src="' + src + '" name="' + Date.now() + '" />';

This fixes the bug in my testing; probably because the window.name in the inner window changes.

You could try either of these. They are not giving me errors.

It is also the suggested method from typescript for array declaration.

By using the Array<Thing> it is making use of the generics in typescript. It is similar to asking for a List<T> in c# code.

// Declare with default value
private _possessions: Array<Thing> = new Array<Thing>();
// or
private _possessions: Array<Thing> = [];
// or -> prefered by ts-lint
private _possessions: Thing[] = [];

or

// declare
private _possessions: Array<Thing>;
// or -> preferd by ts-lint
private _possessions: Thing[];

constructor(){
    //assign
    this._possessions = new Array<Thing>();
    //or
    this._possessions = [];
}

You could also do it more concisely using

driver.find_element_by_id("some_id").size != 0

Since I never can remember that LINQ calls it Where, Select and Aggregate instead of Filter, Map and Reduce so I created a few extension methods you can use:

IEnumerable<string> myStrings = new List<string>() { "1", "2", "3", "4", "5" };
IEnumerable<int> convertedToInts = myStrings.Map(s => int.Parse(s));
IEnumerable<int> filteredInts = convertedToInts.Filter(i => i <= 3); // Keep 1,2,3
int sumOfAllInts = filteredInts.Reduce((sum, i) => sum + i); // Sum up all ints
Assert.Equal(6, sumOfAllInts); // 1+2+3 is 6

Here are the 3 methods (from https://github.com/cs-util-com/cscore/blob/master/CsCore/PlainNetClassLib/src/Plugins/CsCore/com/csutil/collections/IEnumerableExtensions.cs ):

public static IEnumerable<R> Map<T, R>(this IEnumerable<T> self, Func<T, R> selector) {
    return self.Select(selector);
}

public static T Reduce<T>(this IEnumerable<T> self, Func<T, T, T> func) {
    return self.Aggregate(func);
}

public static IEnumerable<T> Filter<T>(this IEnumerable<T> self, Func<T, bool> predicate) {
    return self.Where(predicate);
}

Some more details from https://github.com/cs-util-com/cscore#ienumerable-extensions :

In ReactJS if you are rendering an array of elements you should have a unique key for each those elements. Normally those kinda situations are creating a list.

Example:

function List() {
  const numbers = [0,1,2,3];
 
  return (
    <ul>{numbers.map((n) => <li> {n} </li>)}</ul>
  );
}

 ReactDOM.render(
  <List />,
  document.getElementById('root')
);

In the above example, it creates a dynamic list using li tag, so since li tag does not have a unique key it shows an error.

After fixed:

function List() {
  const numbers = [0,1,2,3];
 
  return (
    <ul>{numbers.map((n) => <li key={n}> {n} </li>)}</ul>
  );
}

 ReactDOM.render(
  <List />,
  document.getElementById('root')
);

Alternative solution when use map when you don't have a unique key (this is not recommended by react eslint ):

function List() {
  const numbers = [0,1,2,3,4,4];
 
  return (
    <ul>{numbers.map((n,i) => <li key={i}> {n} </li>)}</ul>
  );
}

 ReactDOM.render(
  <List />,
  document.getElementById('root')
);

Live example: https://codepen.io/spmsupun/pen/wvWdGwG

Templates:

Pass function name and argument.

<a href="{{ url_for('get_blog_post',id = blog.id)}}">{{blog.title}}</a>

View,function

@app.route('/blog/post/<string:id>',methods=['GET'])
def get_blog_post(id):
    return id

To be totally sure of rather the resultset is empty or not regardless of cursor position, I would do something like this:

public static boolean isMyResultSetEmpty(ResultSet rs) throws SQLException {
    return (!rs.isBeforeFirst() && rs.getRow() == 0);
}

This function will return true if ResultSet is empty, false if not or throw an SQLException if that ResultSet is closed/uninitialized.

Have you tried to specify UserAgent for your request? For example:

request.UserAgent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";

The simplest way is to use: Request::url();

But here is a complex way:

URL::to('/').'/'.Route::getCurrentRoute()->getPath();

The question is contradictory. It asks for a date without a time of day yet displays an example with a time of 00:00:00.

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. See my other Answer for java.time solution.

If instead you want the time-of-day set to the first moment of the day, use a DateTime object on the Joda-Time library and call its withTimeAtStartOfDay method. Be aware that the first moment may not be the time 00:00:00 because of Daylight Saving Time or perhaps other anomalies.

I like the extension method solution..

namespace System
{
    public static class StringExtensions
    {

        public static bool TryParseAsEnum<T>(this string value, out T output) where T : struct
        {
            T result;

            var isEnum = Enum.TryParse(value, out result);

            output = isEnum ? result : default(T);

            return isEnum;
        }
    }
}

Here below my implementation with tests.

using static Microsoft.VisualStudio.TestTools.UnitTesting.Assert;
using static System.Console;

private enum Countries
    {
        NorthAmerica,
        Europe,
        Rusia,
        Brasil,
        China,
        Asia,
        Australia
    }

   [TestMethod]
        public void StringExtensions_On_TryParseAsEnum()
        {
            var countryName = "Rusia";

            Countries country;
            var isCountry = countryName.TryParseAsEnum(out country);

            WriteLine(country);

            IsTrue(isCountry);
            AreEqual(Countries.Rusia, country);

            countryName = "Don't exist";

            isCountry = countryName.TryParseAsEnum(out country);

            WriteLine(country);

            IsFalse(isCountry);
            AreEqual(Countries.NorthAmerica, country); // the 1rst one in the enumeration
        }

Brent - the reason the association is one way has to do with the fact that any class on any component of your CLASSPATH can declare itself in any package (except for java/javax). Thus there just is no mapping of ALL the classes in a given "package" because nobody knows nor can know. You could update a jar file tomorrow and remove or add classes. It's like trying to get a list of all people named John/Jon/Johan in all the countries of the world - none of us is omniscient therefore none of us will ever have the correct answer.

First you have to download file x-plore and installed it.. After that open it and find the thoes you want to edit.. After that just rename the file Xyz.apk to xyz.zip After that open that file and you can see some folders.. then just go and edit the app..

I'm using varchar(15) so far everything is working for me. Insert, Update, Select. I have just started an app that has IP Addresses, though I have not done much dev work yet.

Here is the select statement:

select * From dbo.Server 
where  [IP] = ('132.46.151.181')
Go

A simple counter may solve your problem.

private Integer notificationId = 0;

private Integer incrementNotificationId() {
   return notificationId++;
}

NotificationManager.notify(incrementNotificationId, notification);

Your application must be compiled as a Windows console application.

I have been working on to write a custom module in Drupal 7 and got the same error:

Notice: Trying to get property of non-object

My code is something like this:

function example_node_access($node, $op, $account) {
  if ($node->type == 'page' && $op == 'update') {
    drupal_set_message('This poll has been published, you may not make changes to it.','error');
    return NODE_ACCESS_DENY;    
  }
}

Solution: I just added a condition if (is_object($sqlResult)), and everything went fine.

Here is my final code:

function mediaten_node_access($node, $op, $account) {

    if (is_object($node)){

     if ($node->type == 'page' && $op == 'update') {
       drupal_set_message('This poll has been published, you may not make changes.','error');
       return NODE_ACCESS_DENY;    
      }

    }

}

PHP-Like rounding Method

The code below can be used to add your own version of Math.round to your own namespace which takes a precision parameter. Unlike Decimal rounding in the example above, this performs no conversion to and from strings, and the precision parameter works same way as PHP and Excel whereby a positive 1 would round to 1 decimal place and -1 would round to the tens.

var myNamespace = {};
myNamespace.round = function(number, precision) {
    var factor = Math.pow(10, precision);
    var tempNumber = number * factor;
    var roundedTempNumber = Math.round(tempNumber);
    return roundedTempNumber / factor;
};

myNamespace.round(1234.5678, 1); // 1234.6
myNamespace.round(1234.5678, -1); // 1230

from Mozilla Developer reference for Math.round()

Jon's answer didn't work for me as I got a compiler error CS0453 C# The type must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method

This worked for me though:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<SomeObject>().HasOptional(m => m.somefield);
    base.OnModelCreating(modelBuilder);
}

Note the double nested view. ROWNUM is evaluated before ORDER BY, so it is required for correct numbering.

If you omit ORDER BY clause, you won't get consistent order.

It says timer() is not available on android? You might find this article useful.

http://developer.android.com/resources/articles/timed-ui-updates.html

I was wrong. Timer() is available. It seems you either implement it the way it is one shot operation:

schedule(TimerTask task, Date when) // Schedule a task for single execution.

Or you cancel it after the first execution:

cancel()  // Cancels the Timer and all scheduled tasks.

When you installed MySQL it generated a password for the root user. You can connect using

/usr/local/mysql/bin/mysql -u root -p

and type in the generated password.

Previously, the root user in MySQL used to not have a password and could only connect from localhost. So you would connect using

/usr/local/mysql/bin/mysql -u root

Make sure if your table doesn't already have rows whose Primary Key values are same as the the Primary Key Id in your Query.

If you want to specify only the x-axis, you can do the following:

background-position-x: right 100px;

Not sure if this answers your question or not. Sorry if not

To get the error reported from the mysql database about your query you need to use your connection object as the focus.

so:

echo $mysqliDatabaseConnection->error

would echo the error being sent from mysql about your query.

Hope that helps
