You might be interested in itertools.product, which returns an iterable yielding tuples of values from all the iterables you pass it. That is, itertools.product(A, B) yields all values of the form (a, b), where the a values come from A and the b values come from B. For example:

import itertools

A = [50, 60, 70]
B = [0.1, 0.2, 0.3, 0.4]

print [a + b for a, b in itertools.product(A, B)]

This prints:

[50.1, 50.2, 50.3, 50.4, 60.1, 60.2, 60.3, 60.4, 70.1, 70.2, 70.3, 70.4]

Notice how the final argument passed to itertools.product is the "inner" one. Generally, itertools.product(a0, a1, ... an) is equal to [(i0, i1, ... in) for in in an for in-1 in an-1 ... for i0 in a0]

try this,

string FileNameAndExtension =  "bilah bilah.pdf";
string FileName = FileNameAndExtension.Split('.')[0];

I came accross the same problem. In IE8 it could be worked-around by creating a hidden input after the file input control. The fill this with the value of it's previous sibling. In IE9 this has been fixed aswell.

My reason in wanting to get to know the full path was to create an javascript image preview before uploading. Now I have to upload the file to create a preview of the selected image.

This is what I got from oracle documentation, but it is for oracle 10g release 2:

When you define a NUMBER variable, you can specify its precision (p) and scale (s) so that it is sufficiently, but not unnecessarily, large. Precision is the number of significant digits. Scale can be positive or negative. Positive scale identifies the number of digits to the right of the decimal point; negative scale identifies the number of digits to the left of the decimal point that can be rounded up or down.

The NUMBER data type is supported by Oracle Database standard libraries and operates the same way as it does in SQL. It is used for dimensions and surrogates when a text or INTEGER data type is not appropriate. It is typically assigned to variables that are not used for calculations (like forecasts and aggregations), and it is used for variables that must match the rounding behavior of the database or require a high degree of precision. When deciding whether to assign the NUMBER data type to a variable, keep the following facts in mind in order to maximize performance:

• Analytic workspace calculations on NUMBER variables is slower than other numerical data types because NUMBER values are calculated in software (for accuracy) rather than in hardware (for speed).
• When data is fetched from an analytic workspace to a relational column that has the NUMBER data type, performance is best when the data already has the NUMBER data type in the analytic workspace because a conversion step is not required.

All the above works, and here is another way if you just want to number of days/time back rather a entering date

select * from *table_name* where *datetime_column* BETWEEN DATE_SUB(NOW(), INTERVAL 30 DAY)  AND NOW() 

a = 1
while true
  puts a
  a += 1
  break if a > 10
end

I think this can not be perfectly done for the time being. There are 2 basic problems:

1. How can you make sure the sms is already in the inbox when you try to delete it?
   Notice that SMS_RECEIVED is not an ordered broadcast.
   So dmyung's solution is completely trying one's luck; even the delay in Doug's answer is not a guarantee.

2. The SmsProvider is not thread safe.(refer to http://code.google.com/p/android/issues/detail?id=2916#c0)
   The fact that more than one clients are requesting delete and insert in it at the same time will cause data corruption or even immediate Runtime Exception.

For the absolute coordinates of any jquery element I wrote this function, it probably doesnt work for all css position types but maybe its a good start for someone ..

function AbsoluteCoordinates($element) {
    var sTop = $(window).scrollTop();
    var sLeft = $(window).scrollLeft();
    var w = $element.width();
    var h = $element.height();
    var offset = $element.offset(); 
    var $p = $element;
    while(typeof $p == 'object') {
        var pOffset = $p.parent().offset();
        if(typeof pOffset == 'undefined') break;
        offset.left = offset.left + (pOffset.left);
        offset.top = offset.top + (pOffset.top);
        $p = $p.parent();
    }

    var pos = {
          left: offset.left + sLeft,
          right: offset.left + w + sLeft,
          top:  offset.top + sTop,
          bottom: offset.top + h + sTop,
    }
    pos.tl = { x: pos.left, y: pos.top };
    pos.tr = { x: pos.right, y: pos.top };
    pos.bl = { x: pos.left, y: pos.bottom };
    pos.br = { x: pos.right, y: pos.bottom };
    //console.log( 'left: ' + pos.left + ' - right: ' + pos.right +' - top: ' + pos.top +' - bottom: ' + pos.bottom  );
    return pos;
}

SGML parsers (or XML parsers in the case of XHTML) can handle — without having to process the DTD (which doesn't matter to browsers as they just slurp tag soup), while — is easier for humans to read and write in the source code.

Personally, I would stick to a literal em-dash and ensure that my character encoding settings were consistent.

Don't worry! This problem occurs because of the annotation. Instead of Field based access, Property based access solves this problem. The code as follows:

package onetomanymapping;

import java.util.List;

import javax.persistence.*;

@Entity
public class College {
private int collegeId;
private String collegeName;
private List<Student> students;

@OneToMany(targetEntity = Student.class, mappedBy = "college", 
    cascade = CascadeType.ALL, fetch = FetchType.EAGER)
public List<Student> getStudents() {
    return students;
}

public void setStudents(List<Student> students) {
    this.students = students;
}

@Id
@GeneratedValue
public int getCollegeId() {
    return collegeId;
}

public void setCollegeId(int collegeId) {
    this.collegeId = collegeId;
}

public String getCollegeName() {
    return collegeName;
}

public void setCollegeName(String collegeName) {
    this.collegeName = collegeName;
}

}

In my case it was a project defined using Target Framework: ".NET Framework 4.0 Client Profile " that tried to reference dll projects defined using Target Framework: ".NET Framework 4.0".

Once I changed the project settings to use Target Framework: ".NET Framework 4.0" everything was built nicely.

Right Click the project->Properties->Application->Target Framework

Following are the changes required in your theme for changing action bar & overflow menu background color. You need to configure "android:background" of actionBarStyle & popupMenuStyle

<application
            android:name="...."
            android:theme="@style/AppLightTheme">

<style name="AppLightTheme" parent="android:Theme.Holo.Light">      
        <item name="android:actionBarStyle">@style/ActionBarLight</item>
        <item name="android:popupMenuStyle">@style/ListPopupWindowLight</item>
</style>

<style name="ActionBarLight" parent="android:style/Widget.Holo.Light.ActionBar">
        <item name="android:background">@color/white</item>
</style>


<style name="ListPopupWindowLight"parent="@android:style/Widget.Holo.Light.ListPopupWindow">
        <item name="android:background">@color/white</item>
</style>

The exception can also occur because of the class path not being defined.

After hours of research and literally going through hundreds of pages, the problem was that the class path of the library was not defined.

Set the class path as follows in your windows machine

set classpath=path\to\your\jdbc\jar\file;.

I have had the same issue that I solved this way:

Instead of adding the meta to the current page header that caused the same error as you had:

Page.Header.Controls.Add(meta);

I used this instead:

 Master.FindControl("YourHeadContentPlaceHolder").Controls.Add(meta);

and it works like a charm.

mysqli is provided by php-mysql-5.3.3-40.el6_6.x86_64

You may need to try the following

yum install php-mysql-5.3.3-40.el6_6.x86_64

An example with a little less stringified html:

var container = $('#my-container'),
  table = $('<table>');

users.forEach(function(user) {
  var tr = $('<tr>');
  ['ID', 'Name', 'Address'].forEach(function(attr) {
    tr.append('<td>' + user[attr] + '</td>');
  });
  table.append(tr);
});

container.append(table);

Use JQuery keydown event.

$(document).keypress(function(){
    if(event.which == 70){  //f
        console.log("You have payed respect");
    }
});

In JS; keyboard keys are identified by Javascript keycodes

Try saving DataContext.cs first. It worked for me.

You're close. A really simple solution is just to get the length from the 'run' objects returned. No need to bother with 'load' or 'loads':

len(data['result'][0]['run'])

Just use the following code. It is really useful to send email via Java, and it works:

import java.util.*;
import javax.activation.CommandMap;
import javax.activation.MailcapCommandMap;
import javax.mail.*;
import javax.mail.Provider;
import javax.mail.internet.*;

public class Main {

    public static void main(String[] args) {
            final String username="[email protected]";
            final String password="password";
            Properties prop=new Properties();
            prop.put("mail.smtp.auth", "true");
            prop.put("mail.smtp.host", "smtp.gmail.com");
            prop.put("mail.smtp.port", "587");
            prop.put("mail.smtp.starttls.enable", "true");

            Session session = Session.getDefaultInstance(prop,
          new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
          }
        });
          try {
                 String body="Dear Renish Khunt Welcome";
                 String htmlBody = "<strong>This is an HTML Message</strong>";
                 String textBody = "This is a Text Message.";
         Message message = new MimeMessage(session);
         message.setFrom(new InternetAddress("[email protected]"));
                 message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("[email protected]"));
        message.setSubject("Testing Subject");
        MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
        mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
        mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
        mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
        mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
        mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
        CommandMap.setDefaultCommandMap(mc);
            message.setText(htmlBody);
                        message.setContent(textBody, "text/html");
            Transport.send(message);

            System.out.println("Done");

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

    }

}

You can pass input as ["apple","orange"]if you want to leave the method as it is.

It worked for me with a similar method signature.

I have also researched lot on this, but I could not get the concrete solution for this. Currently the approach I follow is copy the contents in excel from SQL Server Managment studio and then import the data into Oracle-TOAD and then generate the insert statements

Most likely both tables have a column with the same name. Alias each table, and call each column with the table alias.

A potentially simpler solution:

get-service "servicename*" | Where {$_.Status -eq 'Stopped'} | start-service

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

Had a similar problem. Needed to append as many text inputs as the user wanted, to a form. The functionality of it using jQuery was the answer to the question:

<div id='inputdiv'>
<button id='mybutton'>add an input</button>
</div>

<script>
var thecounter=0; //declare and initialize the counter outside of the function
$('#mybutton').on('click', function(){
thecounter++;
$('#inputdiv').append('<input id="input'+thecounter+'" type="text/>);
});
</script>

Adding the count to each new input id resulted in unique ids which lets you get all the values using the jQuery serialize() function.

This function allows you to get the date and time in lots of formats (see the bottom of this post).

# Get the current date or time
def getdatetime(timedateformat='complete'):
    from datetime import datetime
    timedateformat = timedateformat.lower()
    if timedateformat == 'day':
        return ((str(datetime.now())).split(' ')[0]).split('-')[2]
    elif timedateformat == 'month':
        return ((str(datetime.now())).split(' ')[0]).split('-')[1]
    elif timedateformat == 'year':
        return ((str(datetime.now())).split(' ')[0]).split('-')[0]
    elif timedateformat == 'hour':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
    elif timedateformat == 'minute':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]
    elif timedateformat == 'second':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]
    elif timedateformat == 'millisecond':
        return (str(datetime.now())).split('.')[1]
    elif timedateformat == 'yearmonthday':
        return (str(datetime.now())).split(' ')[0]
    elif timedateformat == 'daymonthyear':
        return ((str(datetime.now())).split(' ')[0]).split('-')[2] + '-' + ((str(datetime.now())).split(' ')[0]).split('-')[1] + '-' + ((str(datetime.now())).split(' ')[0]).split('-')[0]
    elif timedateformat == 'hourminutesecond':
        return ((str(datetime.now())).split(' ')[1]).split('.')[0]
    elif timedateformat == 'secondminutehour':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2] + ':' + (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1] + ':' + (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
    elif timedateformat == 'complete':
        return str(datetime.now())
    elif timedateformat == 'datetime':
        return (str(datetime.now())).split('.')[0]
    elif timedateformat == 'timedate':
        return ((str(datetime.now())).split('.')[0]).split(' ')[1] + ' ' + ((str(datetime.now())).split('.')[0]).split(' ')[0]

To obtain the time or date, just use getdatetime("<TYPE>"), replacing <TYPE> with one of the following arguments:

All example outputs use this model information: 25-11-2017 03:23:56.477017

logrotate -d [your_config_file] invokes debug mode, giving you a verbose description of what would happen, but leaving the log files untouched.

Before Mysql version 5.0.3 Varchar datatype can store 255 character, but from 5.0.3 it can be store 65,535 characters.

BUT it has a limitation of maximum row size of 65,535 bytes. It means including all columns it must not be more than 65,535 bytes.

In your case it may possible that when you are trying to set more than 10000 it is exceeding more than 65,535 and mysql will gives the error.

I came up with 4 methods to achieve the results. Here is demo

Method 1:

#a {
    margin-right: auto;
}

Method 2:

#a {
    flex-grow: 1;
}

Method 3:

#b {
    margin-left: auto;
}

Method 4:

#container {
    justify-content: space-between;
}

You simply need a circular array (circular buffer) of 1000 elements, where you add the element to the previous element and store it.

It becomes an increasing sum, where you can always get the sum between any two pairs of elements, and divide by the number of elements between them, to yield the average.

If I wish to submit a http get request using System.Net.HttpClient there seems to be no api to add parameters, is this correct?

Yes.

Is there any simple api available to build the query string that doesn't involve building a name value collection and url encoding those and then finally concatenating them?

Sure:

var query = HttpUtility.ParseQueryString(string.Empty);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
string queryString = query.ToString();

will give you the expected result:

foo=bar%3c%3e%26-baz&bar=bazinga

You might also find the UriBuilder class useful:

var builder = new UriBuilder("http://example.com");
builder.Port = -1;
var query = HttpUtility.ParseQueryString(builder.Query);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
builder.Query = query.ToString();
string url = builder.ToString();

will give you the expected result:

http://example.com/?foo=bar%3c%3e%26-baz&bar=bazinga

that you could more than safely feed to your HttpClient.GetAsync method.

Sorry, not Swift, just a proof of concept in the closest language at hand.

// JavaScript POC. Output:
// Matches:  ["GOODBYE","CRUEL","WORLD","IM","LEAVING","U","TODAY"]

let str = `GOODBYE,CRUEL,WORLD,IM,LEAVING,U,TODAY`
let matches = [];

function recurse(str, matches) {
    let regex = /^((,?([A-Z]+))+)$/gm
    let m
    while ((m = regex.exec(str)) !== null) {
        matches.unshift(m[3])
        return str.replace(m[2], '')
    }
    return "bzzt!"
}

while ((str = recurse(str, matches)) != "bzzt!") ;
console.log("Matches: ", JSON.stringify(matches))

Note: If you were really going to use this, you would use the position of the match as given by the regex match function, not a string replace.

This answer is from 2009. Now a community wiki in case anybody cares to bring it up-to-date.

IE needs a plugin to display SVG. Most common is the one available for download by Adobe; however, Adobe no longer supports or develops it. Firefox, Opera, Chrome, Safari, will all display basic SVG fine but will run into quirks if advanced features are used, as support is incomplete. Firefox has no support for declarative animation.

SVG elements can be created with javascript as follows:

// "circle" may be any tag name
var shape = document.createElementNS("http://www.w3.org/2000/svg", "circle");
// Set any attributes as desired
shape.setAttribute("cx", 25);
shape.setAttribute("cy", 25);
shape.setAttribute("r",  20);
shape.setAttribute("fill", "green");
// Add to a parent node; document.documentElement should be the root svg element.
// Acquiring a parent element with document.getElementById() would be safest.
document.documentElement.appendChild(shape);

The SVG specification describes the DOM interfaces for all SVG elements. For example, the SVGCircleElement, which is created above, has cx, cy, and r attributes for the center point and radius, which can be directly accessed. These are the SVGAnimatedLength attributes, which have a baseVal property for the normal value, and an animVal property for the animated value. Browsers at the moment are not reliably supporting the animVal property. baseVal is an SVGLength, whose value is set by the value property.

Hence, for script animations, one can also set these DOM properties to control SVG. The following code should be equivalent to the above code:

var shape = document.createElementNS("http://www.w3.org/2000/svg", "circle");
shape.cx.baseVal.value = 25;
shape.cy.baseVal.value = 25;
shape.r.baseVal.value = 20;
shape.setAttribute("fill", "green");
document.documentElement.appendChild(shape);

anArray[10][10] is not a pointer to a pointer, it is a contiguous chunk of memory suitable for storing 100 values of type double, which compiler knows how to address because you specified the dimensions. You need to pass it to a function as an array. You can omit the size of the initial dimension, as follows:

void f(double p[][10]) {
}

However, this will not let you pass arrays with the last dimension other than ten.

The best solution in C++ is to use std::vector<std::vector<double> >: it is nearly as efficient, and significantly more convenient.

Use:

str.getBytes("UTF-16LE");

This code adds the amount of years required for a date.

var d = new Date();
// => Tue Oct 01 2017 00:00:00 GMT-0700 (PDT)

var amountOfYearsRequired = 2;
d.setFullYear(d.getFullYear() + amountOfYearsRequired);
// => Tue Oct 01 2019 00:00:00 GMT-0700 (PDT)

Try this:

<a href="#" onclick="return false;">My Link</a>

In C++, there is no difference in main() and main(void).

But in C, main() will be called with any number of parameters.

Example:

main ( ){
    main(10,"abc",12.28);
    //Works fine !
    //It won't give the error. The code will compile successfully.
    //(May cause Segmentation fault when run)
}

main(void) will be called without any parameters. If we try to pass then this end up leading to a compiler error.

Example:

main (void) {
     main(10,"abc",12.13);
     //This throws "error: too many arguments to function ‘main’ "
}

You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close() method:

>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor

The line del f deletes the last reference to the file object, causing its destructor file.__del__ to be called. The internal state of the file object indicates the file is still open since f.close() was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.

Since the implementation of os.system() does not create any Python file objects, it does not seem likely that the system() call is the origin of the error. Maybe you could show a bit more code?

According to the packages list in Ubuntu Wily Xenial Bionic there is a package named openjfx. This should be a candidate for what you're looking for:

JavaFX/OpenJFX 8 - Rich client application platform for Java

You can install it via:

sudo apt-get install openjfx

It provides the following JAR files to the OpenJDK installation on Ubuntu systems:

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar

If you want to have sources available, for example for debugging, you can additionally install:

sudo apt-get install openjfx-source

The dict type has a get function, where if the key doesn't exist in the dictionary, the 2nd argument to get is the value that it should return. Similarly there is setdefault, which returns the value in the dict if the key exists, otherwise it sets the value according to your default parameter and then returns your default parameter.

You could extend the list type to have a getindexdefault method.

class SuperDuperList(list):
    def getindexdefault(self, elem, default):
        try:
            thing_index = self.index(elem)
            return thing_index
        except ValueError:
            return default

Which could then be used like:

mylist = SuperDuperList([0,1,2])
index = mylist.getindexdefault( 'asdf', -1 )

100%-100px is the same

div.thediv {
  width: auto;
  margin-right:100px;
}

With jQuery:

$(window).resize(function(){
  $('.thediv').each(function(){
    $(this).css('width', $(this).parent().width()-100);
  })
});

Similar way is to use jQuery resize plugin

A formula for an angle from 0 to 2pi.

There is x=x2-x1 and y=y2-y1.The formula is working for

any value of x and y. For x=y=0 the result is undefined.

f(x,y)=pi()-pi()/2*(1+sign(x))*(1-sign(y^2))

     -pi()/4*(2+sign(x))*sign(y)

     -sign(x*y)*atan((abs(x)-abs(y))/(abs(x)+abs(y)))

   func weather_diff(country1:String,temp1:Double,country2:String,temp2:Double)->(c1:String,c2:String,diff:Double)
   {
    let c1 = country1
    let c2 = country2
    let diff = temp1 - temp2
    return(c1,c2,diff)
   }

   let result = 
   weather_diff(country1: "India", temp1: 45.5, country2: "Canada", temp2:    18.5)
   print("Weather difference between \(result.c1) and \(result.c2) is \(result.diff)")

For simple cases like this, TimeUnit should be used. TimeUnit usage is a bit more explicit about what is being represented and is also much easier to read and write when compared to doing all of the arithmetic calculations explicitly. For example, to calculate the number days from milliseconds, the following statement would work:

    long days = TimeUnit.MILLISECONDS.toDays(milliseconds);

For cases more advanced, where more finely grained durations need to be represented in the context of working with time, an all encompassing and modern date/time API should be used. For JDK8+, java.time is now included (here are the tutorials and javadocs). For earlier versions of Java joda-time is a solid alternative.

If you want to extend it just because you need Not-Swipeable behaviour, you dont need to do it. ViewPager2 provides nice property called : isUserInputEnabled

You may use mmap to find the offset of the lines. MMap seems to be the fastest way to process a file

example:

with open('input_file', "r+b") as f:
    mapped = mmap.mmap(f.fileno(), 0, prot=mmap.PROT_READ)
    i = 1
    for line in iter(mapped.readline, ""):
        if i == Line_I_want_to_jump:
            offsets = mapped.tell()
        i+=1

then use f.seek(offsets) to move to the line you need

You shouldn't really be de-encrypting passwords.

You should be encrypting the password entered into your application and comparing against the encrypted password from the database.

Edit - and if this is because the password has been forgotten, then setup a mechanism to create a new password.

You might want to look into this C# function to escape the string:

http://www.aspcode.net/C-encode-a-string-for-JSON-JavaScript.aspx

public static string Enquote(string s)  
{ 
    if (s == null || s.Length == 0)  
    { 
        return "\"\""; 
    } 
    char         c; 
    int          i; 
    int          len = s.Length; 
    StringBuilder sb = new StringBuilder(len + 4); 
    string       t; 

    sb.Append('"'); 
    for (i = 0; i < len; i += 1)  
    { 
        c = s[i]; 
        if ((c == '\\') || (c == '"') || (c == '>')) 
        { 
            sb.Append('\\'); 
            sb.Append(c); 
        } 
        else if (c == '\b') 
            sb.Append("\\b"); 
        else if (c == '\t') 
            sb.Append("\\t"); 
        else if (c == '\n') 
            sb.Append("\\n"); 
        else if (c == '\f') 
            sb.Append("\\f"); 
        else if (c == '\r') 
            sb.Append("\\r"); 
        else 
        { 
            if (c < ' ')  
            { 
                //t = "000" + Integer.toHexString(c); 
                string t = new string(c,1); 
                t = "000" + int.Parse(tmp,System.Globalization.NumberStyles.HexNumber); 
                sb.Append("\\u" + t.Substring(t.Length - 4)); 
            }  
            else  
            { 
                sb.Append(c); 
            } 
        } 
    } 
    sb.Append('"'); 
    return sb.ToString(); 
} 

I use WinForms and my way to use File.Exists(string path) is the next one:

public bool FileExists(string fileName)
{
    var workingDirectory = Environment.CurrentDirectory;
    var file = $"{workingDirectory}\{fileName}";
    return File.Exists(file);
}

fileName must include the extension like myfile.txt

The following should work fine.

string[] arr = new string[] {""};

use button type="submit" instead of input

<button type="submit" class="btn btn-success">
    <i class="fa fa-arrow-circle-right fa-lg"></i> Next
</button>

for Font Awesome 3.2.0 use

<button type="submit" class="btn btn-success">
    <i class="icon-circle-arrow-right icon-large"></i> Next
</button>

TL;DR

To get the token in a single oneliner:

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | awk '/^deployment-controller-token-/{print $1}') | awk '$1=="token:"{print $2}'

This assumes that your ~/.kube/config is present and valid. And also that kubectl config get-contexts indicates that you are using the correct context (cluster and namespace) for the dashboard you are logging into.

Explanation

I derived this answer from what I learned from @silverfox's answer. That is a very informative write up. Unfortunately it falls short of telling you how to actually put the information into practice. Maybe I've been doing DevOps too long, but I think in shell. It's much more difficult for me to learn or teach in English.

Here is that oneliner with line breaks and indents for readability:

kubectl -n kube-system describe secret $(
  kubectl -n kube-system get secret | \
  awk '/^deployment-controller-token-/{print $1}'
) | \
awk '$1=="token:"{print $2}'

There are 4 distinct commands and they get called in this order:

• Line 2 - This is the first command from @silverfox's Token section.
• Line 3 - Print only the first field of the line beginning with deployment-controller-token- (which is the pod name)
• Line 1 - This is the second command from @silverfox's Token section.
• Line 5 - Print only the second field of the line whose first field is "token:"

List<target> targetList = new List<target>(originalList.Cast<target>());

You can use INFORMATION_SCHEMA.TABLES to retrieve information about your database tables.

As mentioned in the Microsoft Tables Documentation:

INFORMATION_SCHEMA.TABLES returns one row for each table in the current database for which the current user has permissions.

The following query, therefore, will return the number of tables in the specified database:

USE MyDatabase
SELECT COUNT(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

As of SQL Server 2008, you can also use sys.tables to count the the number of tables.

From the Microsoft sys.tables Documentation:

sys.tables returns a row for each user table in SQL Server.

The following query will also return the number of table in your database:

SELECT COUNT(*)
FROM sys.tables

I have been playing around flexbox lately and i came to solution for this through experimentation and the following reasoning. However, in reality I'm not sure if this is exactly what happens.

If real width is affected by flex system. So after width of elements hit max width of parent they extra width set in css is ignored. Then it's safe to set width to 100%.

Since height of img tag is derived from image itself then setting height to 0% could do something. (this is where i am unclear as to what...but it made sense to me that it should fix it)

DEMO

(remember saw it here first!)

.slider {
    display: flex;
}
.slider img {
    height: 0%;
    width: 100%;
    margin: 0 5px;
}

Works only in chrome yet

On Arch Linux what did the trick for me was:

sudo pacman -Rs npm
sudo pacman -S npm

I would like to know what exactly is the difference between querySelector and querySelectorAll against getElementsByClassName and getElementById?

The syntax and the browser support.

querySelector is more useful when you want to use more complex selectors.

e.g. All list items descended from an element that is a member of the foo class: .foo li

document.querySelector("#view:_id1:inputText1") it doesn't work. But writing document.getElementById("view:_id1:inputText1") works. Any ideas why?

The : character has special meaning inside a selector. You have to escape it. (The selector escape character has special meaning in a JS string too, so you have to escape that too).

document.querySelector("#view\\:_id1\\:inputText1")

SOLUTION

1. Install git filter-repo (Git project recommends filter-repo over filter-branch)

   $ PACKAGE_TOOL install git-filter-repo
   

2. Create a file .mailmap in the root of the git repository containing

   New Name <[email protected]> <[email protected]>
   

3. Run git filter-repo --use-mailmap

MORE DETAILS

• git-filter-repo lists this as an example in their docs
• Instead of replacing both name and email based on email filter as in example above, take a look at additional examples in git mailmap documentation
• Instead of using default .mailmap file you can specify your own by invoking git filter-repo with argument --mailmap <filename>.
• Many more examples on how to further filter branch/tag/whatever can be found in git-filter-repo project's README.md.

    int a = srand(time(NULL))
        arr[i] = a;

Should be

        arr[i] = rand();

And put srand(time(NULL)) somewhere at the very beginning of your program.

This is what I used to start and stop tomcat 7.0.29, using ant 1.8.2. Works fine for me, but leaves the control in the started server window. I have not tried it yet, but I think if I change the "/K" in the startup sequence to "/C", it may not even do that.

<target name="tomcat-stop">
    <exec dir="${appserver.home}/bin" executable="cmd">
        <arg line="/C start cmd.exe /C shutdown.bat"/>
    </exec>
</target>



<target name="tomcat-start" depends="tomcat-stop" >
    <exec dir="${appserver.home}/bin" executable="cmd">
        <arg line="/K start cmd.exe /C startup.bat"/>
    </exec>

</target>

You can use unthrow wrapper

Function<String, Integer> func1 = s -> Unthrow.wrap(() -> myMethod(s));

or

Function<String, Integer> func2 = s1 -> Unthrow.wrap((s2) -> myMethod(s2), s1);

How do I finish the merge after resolving my merge conflicts?

With Git 2.12 (Q1 2017), you will have the more natural command:

git merge --continue

See commit c7d227d (15 Dec 2016) by Jeff King (peff).
See commit 042e290, commit c261a87, commit 367ff69 (14 Dec 2016) by Chris Packham (cpackham).
^{(Merged by Junio C Hamano -- gitster -- in commit 05f6e1b, 27 Dec 2016)}

See 2.12 release notes.

merge: add '--continue' option as a synonym for 'git commit'

Teach 'git merge' the --continue option which allows 'continuing' a merge by completing it.
The traditional way of completing a merge after resolving conflicts is to use 'git commit'.
Now with commands like 'git rebase' and 'git cherry-pick' having a '--continue' option adding such an option to 'git merge' presents a consistent UI.

When you want to access an element, you have to first dereference your pointer, and then index the element you want (which is also dereferncing). i.e. you need to do:

printf("\nvalue:%c", (*ptr)[0]); , which is the same as *((*ptr)+0)

Note that working with pointer to arrays are not very common in C. instead, one just use a pointer to the first element in an array, and either deal with the length as a separate element, or place a senitel value at the end of the array, so one can learn when the array ends, e.g.

char arr[5] = {'a','b','c','d','e',0}; 
char *ptr = arr; //same as char *ptr = &arr[0]

printf("\nvalue:%c", ptr[0]);

Now there's a dedicated function on console for that:

console.trace()

try using 'acroread' in a simple script like the one above

For those coming from GitLab what's worked for me:

Step 1.

add remote

git remote add origin https://<access-token-name>:<access-token>@gitlab.com/path/to/project.git

Step 2.

pull once

https://<access-token-name>:<access-token>@gitlab.com/path/to/project.git

now you are able to read/write to/from repository

Set the Format to Custom and then specify the format:

dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "MM/dd/yyyy hh:mm:ss";  

or however you want to lay it out. You could then type in directly the date/time. If you use MMM, you'll need to use the numeric value for the month for entry, unless you write some code yourself for that (e.g., 5 results in May)

Don't know about the picker for date and time together. Sounds like a custom control to me.

For my Qt project, I use this scheme in *.pro file:

HEADERS += src/dialogs.h
SOURCES += src/main.cpp \
           src/dialogs.cpp

Release:DESTDIR = release
Release:OBJECTS_DIR = release/.obj
Release:MOC_DIR = release/.moc
Release:RCC_DIR = release/.rcc
Release:UI_DIR = release/.ui

Debug:DESTDIR = debug
Debug:OBJECTS_DIR = debug/.obj
Debug:MOC_DIR = debug/.moc
Debug:RCC_DIR = debug/.rcc
Debug:UI_DIR = debug/.ui

It`s simple, but nice! :)

I modified the css, as i am using bootstrap 3.3.6

.form-group.required label:after{   
color: #d00;   
font-family: 'FontAwesome'; 
font-weight: normal;
font-size: 10px;
content: "\f069"; 
top:4px;   
position: absolute;   
 margin-left: 8px;
}

the HTML

<div class="form-group required">
 <label for="return_notes"><?= _lang('notes') ?></label>
 <textarea class="form-control" name="return_notes" id="return_notes"  required="required"></textarea>
</div>

The get method of the HashMap is returning an Object, but the variable current is expected to take a ArrayList:

ArrayList current = new ArrayList();
// ...
current = dictMap.get(dictCode);

For the above code to work, the Object must be cast to an ArrayList:

ArrayList current = new ArrayList();
// ...
current = (ArrayList)dictMap.get(dictCode);

However, probably the better way would be to use generic collection objects in the first place:

HashMap<String, ArrayList<Object>> dictMap =
    new HashMap<String, ArrayList<Object>>();

// Populate the HashMap.

ArrayList<Object> current = new ArrayList<Object>();      
if(dictMap.containsKey(dictCode)) {
    current = dictMap.get(dictCode);   
}

The above code is assuming that the ArrayList has a list of Objects, and that should be changed as necessary.

For more information on generics, The Java Tutorials has a lesson on generics.

The only selector I see is a[id$="name"] (all links with id finishing by "name") but it's not as restrictive as it should.

1. Find file:

   [XAMPP Installation Directory]\php\php.ini
   

2. open php.ini.
3. Find max_execution_time and increase the value of it as you required
4. Restart XAMPP control panel

I would give a min-height and min-width to your overlay div of the size of the image, and change the background color on hover

.overlay { position: absolute; top: 0; left: 0;  z-index: 200; min-height:200px; min-width:200px; background-color: none;}
.overlay:hover { background-color: red;}

If instead of flag = True we can do an import instead, then I think this meets the criteria:

>>> from itertools import count
>>> a = ['hello', '', 'world', '', '', '', 'bob']
>>> filter(lambda L, j=count(): L or not next(j), a)
['hello', '', 'world', 'bob']

Or maybe the filter is better written as:

>>> filter(lambda L, blank_count=count(1): L or next(blank_count) == 1, a)

Or, just for a simple boolean, without any imports:

filter(lambda L, use_blank=iter([True]): L or next(use_blank, False), a)

You need to use the 'g' switch for a global search

var result = mystring.match(/(&|&)?([^=]+)=([^&]+)/g)

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.

"Stack Me 123 Heppa1 oeu".toCharArray() ?

Remember to use the server's local name, not the domain name, when resolving the name

IIS AppPool\DefaultAppPool

(just a reminder because this tripped me up for a bit):

I'll try to answer the why question: The Java array is very simple and rudimentary compared to classes like ArrayList, that are more dynamic. Java wants to know at declaration time how much memory should be allocated for the array. An ArrayList is much more dynamic and the size of it can vary over time.

If you initialize your array with the length of two, and later on it turns out you need a length of three, you have to throw away what you've got, and create a whole new array. Therefore the 'new' keyword.

In your first two examples, you tell at declaration time how much memory to allocate. In your third example, the array name becomes a pointer to nothing at all, and therefore, when it's initialized, you have to explicitly create a new array to allocate the right amount of memory.

I would say that (and if someone knows better, please correct me) the first example

AClass[] array = {object1, object2}

actually means

AClass[] array = new AClass[]{object1, object2};

but what the Java designers did, was to make quicker way to write it if you create the array at declaration time.

The suggested workarounds are good. If the time or memory usage is critical at runtime, use arrays. If it's not critical, and you want code that is easier to understand and to work with, use ArrayList.

 //Saving each element of the input file in an arraylist 
    ArrayList<String> list = new ArrayList<String>();
    while (s.hasNext()){
        list.add(s.next());
    }

//That's all you need
list = (ArrayList) list.stream().distinct().collect(Collectors.toList());

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

I think you are looking for UPDATE and not insert?

UPDATE `users`
SET `username` = 'Jack', `password` = '123'
WHERE `id` = 1

for making uppercase from lowercase to upper just use

"string".upper()

where "string" is your string that you want to convert uppercase

for this question concern it will like this:

s.upper()

for making lowercase from uppercase string just use

"string".lower()

where "string" is your string that you want to convert lowercase

for this question concern it will like this:

s.lower()

If you want to make your whole string variable use

s="sadf"
# sadf

s=s.upper()
# SADF

To add to @mrry's post, I put together a tutorial that explains how to load a TensorFlow graph with the C++ API. It's very minimal and should help you understand how all of the pieces fit together. Here's the meat of it:

Requirements:

• Bazel installed
• Clone TensorFlow repo

Folder structure:

• tensorflow/tensorflow/|project name|/
• tensorflow/tensorflow/|project name|/|project name|.cc (e.g. https://gist.github.com/jimfleming/4202e529042c401b17b7)
• tensorflow/tensorflow/|project name|/BUILD

BUILD:

cc_binary(
    name = "<project name>",
    srcs = ["<project name>.cc"],
    deps = [
        "//tensorflow/core:tensorflow",
    ]
)

Two caveats for which there are probably workarounds:

• Right now, building things needs to happen within the TensorFlow repo.
• The compiled binary is huge (103MB).

To pretty print the column data types

To check the data types after, for example, an import from a file

def printColumnInfo(df):
    template="%-8s %-30s %s"
    print(template % ("Type", "Column Name", "Example Value"))
    print("-"*53)
    for c in df.columns:
        print(template % (df[c].dtype, c, df[c].iloc[1]) )

Illustrative output:

Type     Column Name                    Example Value
-----------------------------------------------------
int64    Age                            49
object   Attrition                      No
object   BusinessTravel                 Travel_Frequently
float64  DailyRate                      279.0

n = eval(input('Num books: '))
books = {}
for i in range(n):
    titlez = input("Enter Title: ")
    copy = eval(input("Num of copies: "))
    books[titlez] = copy

prob = input('Sell a book; enter YES or NO: ')
if prob == 'YES' or 'yes':
    choice = input('Enter book title: ')
    if choice in books:
        init_num = books[choice]
        init_num -= 1
        books[choice] = init_num
        print(books)

is this is a WordPress? You shouldn't do it like you've done! To get option from DB use get_option!

If you are getting this error 'Template not provided ...." again and again, then straigt away do the followiong to steps:

1. npm uninstall -g create-react-app
2. check the location of your file 'create-react-app' by using the command "which create-react-app"
3. Now manually delete that file using the command "rm -rf /usr/local/bin/create-react-app" replacing this command with the exact path shown in the previous step.
4. Finally run 'npx create-react-app '

This will replace your old file 'create-react-app' which is causing the problem with the new file downloaded with npx.

Happy coding...

Short answer: using as.data.frame.matrix(mytable), as @Victor Van Hee suggested.

Long answer: as.data.frame(mytable) may not work on contingency tables generated by table() function, even if is.matrix(your_table) returns TRUE. It will still melt you table into the factor1 factor2 factori counts format.

Example:

> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)

> freq_t
   gear
cyl  3  4  5
  4  1  8  2
  6  2  4  1
  8 12  0  2

> is.matrix(freq_t)
[1] TRUE

> as.data.frame(freq_t)
  cyl gear Freq
1   4    3    1
2   6    3    2
3   8    3   12
4   4    4    8
5   6    4    4
6   8    4    0
7   4    5    2
8   6    5    1
9   8    5    2
> as.data.frame.matrix(freq_t)
   3 4 5
4  1 8 2
6  2 4 1
8 12 0 2

Here's a solution which reports the correct first responder (many other solutions won't report a UIViewController as the first responder, for example), doesn't require looping over the view hierarchy, and doesn't use private APIs.

It leverages Apple's method sendAction:to:from:forEvent:, which already knows how to access the first responder.

We just need to tweak it in 2 ways:

• Extend UIResponder so it can execute our own code on the first responder.
• Subclass UIEvent in order to return the first responder.

Here is the code:

@interface ABCFirstResponderEvent : UIEvent
@property (nonatomic, strong) UIResponder *firstResponder;
@end

@implementation ABCFirstResponderEvent
@end

@implementation UIResponder (ABCFirstResponder)
- (void)abc_findFirstResponder:(id)sender event:(ABCFirstResponderEvent *)event {
    event.firstResponder = self;
}
@end

@implementation ViewController

+ (UIResponder *)firstResponder {
    ABCFirstResponderEvent *event = [ABCFirstResponderEvent new];
    [[UIApplication sharedApplication] sendAction:@selector(abc_findFirstResponder:event:) to:nil from:nil forEvent:event];
    return event.firstResponder;
}

@end

Be sure to insert full version of jQuery UI. Also you should init the dialog first:

$(function () {_x000D_
  $( "#dialog1" ).dialog({_x000D_
    autoOpen: false_x000D_
  });_x000D_
  _x000D_
  $("#opener").click(function() {_x000D_
    $("#dialog1").dialog('open');_x000D_
  });_x000D_
});

<script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>_x000D_
 _x000D_
<script src="https://code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>_x000D_
_x000D_
<link rel="stylesheet" href="https://code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css" />_x000D_
_x000D_
<button id="opener">open the dialog</button>_x000D_
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>

Are you looking for this selector?:

.ui-menu .ui-menu-item a{
    background:red;
    height:10px;
    font-size:8px;
}

Ugly demo:

http://jsfiddle.net/zeSTc/

Just replace with your code:

.ui-menu .ui-menu-item a{
    color: #96f226;
    border-radius: 0px;
    border: 1px solid #454545;

Install AWS CLI:

curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
sudo apt-get install unzip
unzip awscli-bundle.zip
sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

Get the tags for the current instance:

aws ec2 describe-tags --filters "Name=resource-id,Values=`ec2metadata --instance-id`"

Outputs:

{
    "Tags": [
        {
            "ResourceType": "instance", 
            "ResourceId": "i-6a7e559d", 
            "Value": "Webserver", 
            "Key": "Name"
        }
    ]
}

Use a bit of perl to extract the tags:

aws ec2 describe-tags --filters \
"Name=resource-id,Values=`ec2metadata --instance-id`" | \
perl -ne 'print "$1\n" if /\"Value\": \"(.*?)\"/'

Returns:

Webserver

In recent versions of python, you can use marshmallow-dataclass:

from marshmallow_dataclass import dataclass

@dataclass
class Payload
    action:str
    method:str
    data:str

Payload.Schema().load({"action":"print","method":"onData","data":"Madan Mohan"})

After struggling, this worked for me for moment v2.26.0:

import React from "react";
import moment from "moment";
import frLocale from "moment/locale/fr";
import esLocale from "moment/locale/es";

export default function App() {
  moment.locale('fr', [frLocale, esLocale]) // can pass in 'en', 'fr', or 'es'

  let x = moment("2020-01-01 00:00:01");
  return (
    <div className="App">
      {x.format("LLL")}
      <br />
      {x.fromNow()}
    </div>
  );
}

You can pass in en, fr or es. If you wanted another language, you'd have to import the locale and add it to the array.

If you only need to support one language it is a bit simpler:

import React from "react";
import moment from "moment";
import "moment/locale/fr"; //always use French

export default function App() {  
  let x = moment("2020-01-01 00:00:01");
  return (
    <div className="App">
      {x.format("LLL")}
      <br />
      {x.fromNow()}
    </div>
  );
}

If possible, you may want to use IPython.

To get a list of all current user-defined variables, IPython provides a magic command named who (magics must be prefixed with the modulo character unless the automagic feature is enabled):

In [1]: foo = 'bar'
In [2]: %who
foo

You can use the whos magic to get more detail:

In [3]: %whos
Variable   Type    Data/Info
----------------------------
foo        str     bar

There are a wealth of other magics available. IPython is basically the Python interpreter on steroids. One convenient magic is store, which lets you save variables between sessions (using pickle).

Note: I am not associated with IPython Dev - just a satisfied user.

Edit:

You can find all the magic commands in the IPython Documentation.

This article also has a helpful section on the use of magic commands in Jupyter Notebook

That DateTime format is actually ISO 8601 DateTime. JSON does not specify any particular format for dates/times. If you Google a bit, you will find plenty of implementations to parse it in Java.

Here's one

If you are open to using something other than Java's built-in Date/Time/Calendar classes, I would also suggest Joda Time. They offer (among many things) a ISODateTimeFormat to parse these kinds of strings.

I had this issue and tried both, but had to settle for removing crap like "pageEditState", but not removing user info lest I have to look it up again.

public static void RemoveEverythingButUserInfo()
{
    foreach (String o in HttpContext.Current.Session.Keys)
    {
        if (o != "UserInfoIDontWantToAskForAgain")
            keys.Add(o);
    }
}

int means interrupt, and the number 0x80 is the interrupt number. An interrupt transfers the program flow to whomever is handling that interrupt, which is interrupt 0x80 in this case. In Linux, 0x80 interrupt handler is the kernel, and is used to make system calls to the kernel by other programs.

The kernel is notified about which system call the program wants to make, by examining the value in the register %eax (AT&T syntax, and EAX in Intel syntax). Each system call have different requirements about the use of the other registers. For example, a value of 1 in %eax means a system call of exit(), and the value in %ebx holds the value of the status code for exit().

You may follow the script which is developed using PHP. Where you can download any google fonts by using the script. It will download the fonts and create a CSS file and archive to zip.
You can download the source code from the GitHub https://github.com/sourav101/google-fonts-downloader

It is possible to load the second version of the jQuery use it and then restore to the original or keep the second version if there was no jQuery loaded before. Here is an example:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
    var jQueryTemp = jQuery.noConflict(true);
    var jQueryOriginal = jQuery || jQueryTemp;
    if (window.jQuery){
        console.log('Original jQuery: ', jQuery.fn.jquery);
        console.log('Second jQuery: ', jQueryTemp.fn.jquery);
    }
    window.jQuery = window.$ = jQueryTemp;
</script>
<script type="text/javascript">
    console.log('Script using second: ', jQuery.fn.jquery);
</script>
<script type="text/javascript">
    // Restore original jQuery:
    window.jQuery = window.$ = jQueryOriginal;
    console.log('Script using original or the only version: ', jQuery.fn.jquery);
</script>

Use following code to perform if-else conditioning in python: Here, I am checking the length of the string. If the length is less than 3 then do nothing, if more then 3 then I check the last 3 characters. If last 3 characters are "ing" then I add "ly" at the end otherwise I add "ing" at the end.

Code-

if (len(s)<=3):
    return s
elif s[-3:]=="ing":
    return s+"ly"
else: return s + "ing"

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

If you were using IBM Informix Dynamic Server, you would have a MONEY type which is a minor variant on the DECIMAL or NUMERIC type. It is always a fixed-point type (whereas DECIMAL can be a floating point type). You can specify a scale from 1 to 32, and a precision from 0 to 32 (defaulting to a scale of 16 and a precision of 2). So, depending on what you need to store, you might use DECIMAL(16,2) - still big enough to hold the US Federal Deficit, to the nearest cent - or you might use a smaller range, or more decimal places.

List<int> list = new List<int> { 5, 7, 3 };  
list.Sort((x,y)=> y.CompareTo(x));  
list.ForEach(action => { Console.Write(action + " "); });

If you are using the SQL Management Studio, you can right click your DB name and select Tasks > Import/Export data and follow the wizard.
one of the steps is called "Specify Table Copy or Query" where there is an option to write a query to specify the data to transfer, so you can simply specify the following query:

select * from [Table] where Fk_CompanyId = 1

This is also useful:

SELECT t.*
FROM (
  SELECT e1.*
    , row_number() OVER (ORDER BY e1.Rate DESC) AS _Rank
  FROM
  HumanResources.EmployeePayHistory AS e1
) AS t
WHERE t._Rank = 2

How to debug a MySQL stored procedure.

Poor mans debugger:

1. Create a table called logtable with two columns, id INT and log VARCHAR(255).

2. Make the id column autoincrement.

3. Use this procedure:

   delimiter //
   DROP PROCEDURE `log_msg`//
   CREATE PROCEDURE `log_msg`(msg VARCHAR(255))
   BEGIN
       insert into logtable select 0, msg;
   END
   

4. Put this code anywhere you want to log a message to the table.

   call log_msg(concat('myvar is: ', myvar, ' and myvar2 is: ', myvar2));
   

It's a nice quick and dirty little logger to figure out what is going on.

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:

<script type="text/javascript">
$(function() {
  $('form').submit(function(){
    $.post('http://example.com/upload', function() {
      window.location = 'http://google.com';
    });
    return false;
  });
});
</script>

You might want to check a few things:

1. You production server allows remote connections. (possible that someone turned this off, especially if you have a DBA)

2. Check your connection string. Sometimes if you are using an ip address or server name this will cause this error. Try both.

You can add to your css .erb extension. Ej: style.css.erb

Then you can put:

background: url(<%= asset_path 'logo.png' %>) no-repeat;

If you enabled it as a DHCP client then your router should get an IP address from a DHCP server. If you connect your router on a net with a DHCP server you should reach your router's administrator page on the IP address assigned by the DHCP.

sleep 6 will sleep for 6 seconds. For a longer duration, you can also use sleep(6.minutes) or sleep(6.hours).

I think, the Dropdown box with a class and JQuery code to disable the first option for user to select, will work perfectly as Select Box placeholder.

<select class="selectboxclass">
   <option value="">- Please Select -</option>
   <option value="IN">India</option>
   <option value="US">America</option>
</select>

Make the first option disabled by JQuery.

<script>
$('select.selectboxclass option:first').attr('disabled', true);
</script>

This will make the first option of Dropdown as Placeholder and user will no longer able to select the first option.

Hope It helps!!

I know I am late to the show with this one, but I used this - pretty simple approach. This allows you to get the 60 minute slices without any rounding issues.

Select 
   CONCAT( 
            Format(endtime,'yyyy-MM-dd_HH:'),  
            LEFT(Format(endtime,'mm'),1),
            '0' 
          ) as [Time-Slice]

go to config/environments/test.rb

Rails.application.routes.default_url_options[:host] = 'localhost:3000'

Others have answered that export makes the variable available to subshells, and that is correct but merely a side effect. When you export a variable, it puts that variable in the environment of the current shell (ie the shell calls putenv(3) or setenv(3)).
The environment of a process is inherited across exec, making the variable visible in subshells.

Edit (with 5 year's perspective): this is a silly answer. The purpose of 'export' is to make variables "be in the environment of subsequently executed commands", whether those commands be subshells or subprocesses. A naive implementation would be to simply put the variable in the environment of the shell, but this would make it impossible to implement export -p.

The main idea of random is that it returns a pseudorandom value. There is no such thing as fully random functions, hence, 2 Random instances using the same seed will return the same value in certain conditions.

It is a good practice to first view the function doc in order to understand it (https://docs.oracle.com/javase/8/docs/api/java/util/Random.html)

Now that we understand that the returned value of the function nextDouble() is a pseudorandom value between 0.0 and 1.0 we can use it to our advantage.

For creating a random number between A and B givin' that the boundaries are valid (A>B) we need to: 1. find the range between A and B so we can know how to many "steps" we have. 2. use the random function to determine how many steps to take (because the returned value is between 0.0 and 1.0 you can think of it as "pick a random percentage of increase" 3. add the offset

After all of that, you can see that mob gave you the easiest and most common way to do so in my opinion

double randomValue = rangeMin + (rangeMax - rangeMin) * r.nextDouble();

double RandomValue = Offset + (Range)*(randomVal between 0.0-1.0)

I authored the G2 project, a friendly environment for the command line git lover.
Please get the project from github - G2 https://github.com/orefalo/g2

It has a bunch of handy commands, one of them being exactly what your are looking for: freeze

freeze - Freeze all files in the repository (additions, deletions, modifications) to the staging area, thus staging that content for inclusion in the next commit. Also accept a specific path as parameter

I think this could help you:

let timeNow = time(nil)
let aStr = String(format: "%@%x", "timeNow in hex: ", timeNow)
print(aStr)

Example result:

timeNow in hex: 5cdc9c8d

Ajax is a way of using Javascript for communicating with serverside without loading the page over again. jQuery uses ajax for many of its functions, but it nothing else than a library that provides easier functionality.

With jQuery you dont have to think about creating xml objects ect ect, everything is done for you, but with straight up javascript ajax you need to program every single step of the ajax call.

Use the following notations:

• For "C:\Program Files", use "C:\PROGRA~1"
• For "C:\Program Files (x86)", use "C:\PROGRA~2"

Thanks @lit for your ideal answer in below comment:

Use the environment variables %ProgramFiles% and %ProgramFiles(x86)%

unicode is meant to handle text. Text is a sequence of code points which may be bigger than a single byte. Text can be encoded in a specific encoding to represent the text as raw bytes(e.g. utf-8, latin-1...).

Note that unicode is not encoded! The internal representation used by python is an implementation detail, and you shouldn't care about it as long as it is able to represent the code points you want.

On the contrary str in Python 2 is a plain sequence of bytes. It does not represent text!

You can think of unicode as a general representation of some text, which can be encoded in many different ways into a sequence of binary data represented via str.

Note: In Python 3, unicode was renamed to str and there is a new bytes type for a plain sequence of bytes.

Some differences that you can see:

>>> len(u'à')  # a single code point
1
>>> len('à')   # by default utf-8 -> takes two bytes
2
>>> len(u'à'.encode('utf-8'))
2
>>> len(u'à'.encode('latin1'))  # in latin1 it takes one byte
1
>>> print u'à'.encode('utf-8')  # terminal encoding is utf-8
à
>>> print u'à'.encode('latin1') # it cannot understand the latin1 byte
?

Note that using str you have a lower-level control on the single bytes of a specific encoding representation, while using unicode you can only control at the code-point level. For example you can do:

>>> 'àèìòù'
'\xc3\xa0\xc3\xa8\xc3\xac\xc3\xb2\xc3\xb9'
>>> print 'àèìòù'.replace('\xa8', '')
à?ìòù

What before was valid UTF-8, isn't anymore. Using a unicode string you cannot operate in such a way that the resulting string isn't valid unicode text. You can remove a code point, replace a code point with a different code point etc. but you cannot mess with the internal representation.

If a path may contain parentheses then the r'\(.*?\)' regex is not enough:

import os, re

def remove_parenthesized_chunks(path, safeext=True, safedir=True):
    dirpath, basename = os.path.split(path) if safedir else ('', path)
    name, ext = os.path.splitext(basename) if safeext else (basename, '')
    name = re.sub(r'\(.*?\)', '', name)
    return os.path.join(dirpath, name+ext)

By default the function preserves parenthesized chunks in directory and extention parts of the path.

Example:

>>> f = remove_parenthesized_chunks
>>> f("Example_file_(extra_descriptor).ext")
'Example_file_.ext'
>>> path = r"c:\dir_(important)\example(extra).ext(untouchable)"
>>> f(path)
'c:\\dir_(important)\\example.ext(untouchable)'
>>> f(path, safeext=False)
'c:\\dir_(important)\\example.ext'
>>> f(path, safedir=False)
'c:\\dir_\\example.ext(untouchable)'
>>> f(path, False, False)
'c:\\dir_\\example.ext'
>>> f(r"c:\(extra)\example(extra).ext", safedir=False)
'c:\\\\example.ext'

Install python-dotenv in your virtual environment.

Create a .flaskenv in your project root. By project root, I mean the folder which has your app.py file

Inside this file write the following:

FLASK_APP=myapp 
FLASK_ENV=development

Now issue the following command:

flask run

This issue is not solved (yet), at least not easily / without scripting: see this post on git mailing list by Junio C Hamano explaining situation and providing call for a simple solution.

The major reasoning is that you shouldn't need this:

With git that is not ancient (i.e. v1.5.0 or newer), there is no reason to have local "dev" that purely track the remote anymore. If you only want to go-look-and-see, you can check out the remote tracking branch directly on a detached HEAD with "git checkout origin/dev".

Which means that the only cases we need to make it convenient for users are to handle these local branches that "track" remote ones when you do have local changes, or when you plan to have some.

If you do have local changes on "dev" that is marked to track the remove "dev", and if you are on a branch different from "dev", then we should not do anything after "git fetch" updates the remote tracking "dev". It won't fast forward anyway

The call for a solution was for an option or external script to prune local branches that follow now remote-tracking branches, rather than to keep them up-to-date by fast-forwarding, like original poster requested.

So how about "git branch --prune --remote=<upstream>" that iterates over local branches, and if

(1) it is not the current branch; and
(2) it is marked to track some branch taken from the <upstream>; and
(3) it does not have any commits on its own;

then remove that branch? "git remote --prune-local-forks <upstream>" is also fine; I do not care about which command implements the feature that much.

Note: as of git 2.10 no such solution exists. Note that the git remote prune subcommand, and git fetch --prune are about removing remote-tracking branch for branch that no longer exists on remote, not about removing local branch that tracks remote-tracking branch (for which remote-tracking branch is upstream branch).

Simply adding it to the root folder works after a fashion, but I've found that if I need to change the favicon, it can take days to update... even a cache refresh doesn't do the trick.

As the Jquery replaceWith() code was too bulky, tricky and complicated, here's my own solution. =)

The best way is to use outerHTML property, but it is not crossbrowsered yet, so I did some trick, weird enough, but simple.

Here is the code

var str = '<a href="http://www.com">item to replace</a>'; //it can be anything
var Obj = document.getElementById('TargetObject'); //any element to be fully replaced
if(Obj.outerHTML) { //if outerHTML is supported
    Obj.outerHTML=str; ///it's simple replacement of whole element with contents of str var
}
else { //if outerHTML is not supported, there is a weird but crossbrowsered trick
    var tmpObj=document.createElement("div");
    tmpObj.innerHTML='<!--THIS DATA SHOULD BE REPLACED-->';
    ObjParent=Obj.parentNode; //Okey, element should be parented
    ObjParent.replaceChild(tmpObj,Obj); //here we placing our temporary data instead of our target, so we can find it then and replace it into whatever we want to replace to
    ObjParent.innerHTML=ObjParent.innerHTML.replace('<div><!--THIS DATA SHOULD BE REPLACED--></div>',str);
}

That's all

Running assembly Code on Mac is just 3 steps away from you. It could be done using XCODE but better is to use NASM Command Line Tool. For My Ease I have already installed Xcode, if you have Xcode installed its good.

But You can do it without XCode as well.

Just Follow:

1. First Install NASM using Homebrew brew install nasm
2. convert .asm file into Obj File using this command nasm -f macho64 myFile.asm
3. Run Obj File to see OutPut using command ld -macosx_version_min 10.7.0 -lSystem -o OutPutFile myFile.o && ./64

Simple Text File named myFile.asm is written below for your convenience.

global start
section .text

start:
    mov     rax, 0x2000004 ; write
    mov     rdi, 1 ; stdout
    mov     rsi, msg
    mov     rdx, msg.len
    syscall

    mov     rax, 0x2000001 ; exit
    mov     rdi, 0
    syscall

section .data

msg:    db      "Assalam O Alaikum Dear", 10
.len:   equ     $ - msg

It seems that one of the most common reasons this happens is if you install a new version of PostgreSQL without stopping the service of an existing installation. This was a particular headache of mine, too. Before installing or upgrading, particularly on OS X and using the one click installer from Enterprise DB, make sure you check the status of the old installation before proceeding.

Since you are using WebSocket, spender is correct. After recieving the initial data from the WebSocket, you need to send the handshake message from the C# server before any further information can flow.

HTTP/1.1 101 Web Socket Protocol Handshake
Upgrade: websocket
Connection: Upgrade
WebSocket-Origin: example
WebSocket-Location: something.here
WebSocket-Protocol: 13

Something along those lines.

You can do some more research into how WebSocket works on w3 or google.

I needed to load the settings file synchronously, and this was my solution:

export function InitConfig(config: AppConfig) { return () => config.load(); }

import { Injectable } from '@angular/core';

@Injectable()
export class AppConfig {
    Settings: ISettings;

    constructor() { }

    load() {
        return new Promise((resolve) => {
            this.Settings = this.httpGet('assets/clientsettings.json');
            resolve(true);
        });
    }

    httpGet(theUrl): ISettings {
        const xmlHttp = new XMLHttpRequest();
        xmlHttp.open( 'GET', theUrl, false ); // false for synchronous request
        xmlHttp.send( null );
        return JSON.parse(xmlHttp.responseText);
    }
}

This is then provided as a app_initializer which is loaded before the rest of the application.

app.module.ts

{
      provide: APP_INITIALIZER,
      useFactory: InitConfig,
      deps: [AppConfig],
      multi: true
    },

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

Well, reading it isn't hard, just use FileStream to read a byte[]. Converting it to text isn't really generally possible or meaningful unless you convert the 1's and 0's to hex. That's easy to do with the BitConverter.ToString(byte[]) overload. You'd generally want to dump 16 or 32 bytes in each line. You could use Encoding.ASCII.GetString() to try to convert the bytes to characters. A sample program that does this:

using System;
using System.IO;
using System.Text;

class Program {
    static void Main(string[] args) {
        // Read the file into <bits>
        var fs = new FileStream(@"c:\temp\test.bin", FileMode.Open);
        var len = (int)fs.Length;
        var bits = new byte[len];
        fs.Read(bits, 0, len);
        // Dump 16 bytes per line
        for (int ix = 0; ix < len; ix += 16) {
            var cnt = Math.Min(16, len - ix);
            var line = new byte[cnt];
            Array.Copy(bits, ix, line, 0, cnt);
            // Write address + hex + ascii
            Console.Write("{0:X6}  ", ix);
            Console.Write(BitConverter.ToString(line));
            Console.Write("  ");
            // Convert non-ascii characters to .
            for (int jx = 0; jx < cnt; ++jx)
                if (line[jx] < 0x20 || line[jx] > 0x7f) line[jx] = (byte)'.';
            Console.WriteLine(Encoding.ASCII.GetString(line));
        }
        Console.ReadLine();
    }
}

Incase people have a problem like myself following Marwan Aouida's answer ... the code has a small typo. Instead of "success" it says "sucess" change the spelling and the code works fine.

There is now an ELMAH.MVC package in NuGet that includes an improved solution by Atif and also a controller that handles the elmah interface within MVC routing (no need to use that axd anymore)
The problem with that solution (and with all the ones here) is that one way or another the elmah error handler is actually handling the error, ignoring what you might want to set up as a customError tag or through ErrorHandler or your own error handler
The best solution IMHO is to create a filter that will act at the end of all the other filters and log the events that have been handled already. The elmah module should take care of loging the other errors that are unhandled by the application. This will also allow you to use the health monitor and all the other modules that can be added to asp.net to look at error events

I wrote this looking with reflector at the ErrorHandler inside elmah.mvc

public class ElmahMVCErrorFilter : IExceptionFilter
{
   private static ErrorFilterConfiguration _config;

   public void OnException(ExceptionContext context)
   {
       if (context.ExceptionHandled) //The unhandled ones will be picked by the elmah module
       {
           var e = context.Exception;
           var context2 = context.HttpContext.ApplicationInstance.Context;
           //TODO: Add additional variables to context.HttpContext.Request.ServerVariables for both handled and unhandled exceptions
           if ((context2 == null) || (!_RaiseErrorSignal(e, context2) && !_IsFiltered(e, context2)))
           {
            _LogException(e, context2);
           }
       }
   }

   private static bool _IsFiltered(System.Exception e, System.Web.HttpContext context)
   {
       if (_config == null)
       {
           _config = (context.GetSection("elmah/errorFilter") as ErrorFilterConfiguration) ?? new ErrorFilterConfiguration();
       }
       var context2 = new ErrorFilterModule.AssertionHelperContext((System.Exception)e, context);
       return _config.Assertion.Test(context2);
   }

   private static void _LogException(System.Exception e, System.Web.HttpContext context)
   {
       ErrorLog.GetDefault((System.Web.HttpContext)context).Log(new Elmah.Error((System.Exception)e, (System.Web.HttpContext)context));
   }


   private static bool _RaiseErrorSignal(System.Exception e, System.Web.HttpContext context)
   {
       var signal = ErrorSignal.FromContext((System.Web.HttpContext)context);
       if (signal == null)
       {
           return false;
       }
       signal.Raise((System.Exception)e, (System.Web.HttpContext)context);
       return true;
   }
}

Now, in your filter config you want to do something like this:

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        //These filters should go at the end of the pipeline, add all error handlers before
        filters.Add(new ElmahMVCErrorFilter());
    }

Notice that I left a comment there to remind people that if they want to add a global filter that will actually handle the exception it should go BEFORE this last filter, otherwise you run into the case where the unhandled exception will be ignored by the ElmahMVCErrorFilter because it hasn't been handled and it should be loged by the Elmah module but then the next filter marks the exception as handled and the module ignores it, resulting on the exception never making it into elmah.

Now, make sure the appsettings for elmah in your webconfig look something like this:

<add key="elmah.mvc.disableHandler" value="false" /> <!-- This handles elmah controller pages, if disabled elmah pages will not work -->
<add key="elmah.mvc.disableHandleErrorFilter" value="true" /> <!-- This uses the default filter for elmah, set to disabled to use our own -->
<add key="elmah.mvc.requiresAuthentication" value="false" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.allowedRoles" value="*" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.route" value="errortracking" /> <!-- Base route for elmah pages -->

The important one here is "elmah.mvc.disableHandleErrorFilter", if this is false it will use the handler inside elmah.mvc that will actually handle the exception by using the default HandleErrorHandler that will ignore your customError settings

This setup allows you to set your own ErrorHandler tags in classes and views, while still loging those errors through the ElmahMVCErrorFilter, adding a customError configuration to your web.config through the elmah module, even writing your own Error Handlers. The only thing you need to do is remember to not add any filters that will actually handle the error before the elmah filter we've written. And I forgot to mention: no duplicates in elmah.

I'd advise against using shorttags, see Are PHP short tags acceptable to use? for more information on why.

Personally I don't mind mixing HTML and PHP like so

<a href="<?php echo $link;?>">link description</a>

As long as I have a code-editor with good syntax highlighting, I think this is pretty readable. If you start echoing HTML with PHP then you lose all the advantages of syntax highlighting your HTML. Another disadvantage of echoing HTML is the stuff with the quotes, the following is a lot less readable IMHO.

echo '<a href="'.$link.'">link description</a>';

The biggest advantage for me with simple echoing and simple looping in PHP and doing the rest in HTML is that indentation is consistent, which in the end improves readability/scannability.

Should be easier since this bug is fixed in maven-help-plugin 3.0.0: MPH-99 Evaluate has no output in quiet mode.

Have a look at this presentation.

According to this pattern - create transient restful resources to manage state if and when really needed. Avoid explicit sessions.

A good explanation for this can be found here

To summarize : The number N in int(N) is often confused by the maximum size allowed for the column, as it does in the case of varchar(N).

But this is not the case with Integer data types- the number N in the parentheses is not the maximum size for the column, but simply a parameter to tell MySQL what width to display the column at when the table's data is being viewed via the MySQL console (when you're using the ZEROFILL attribute).

The number in brackets will tell MySQL how many zeros to pad incoming integers with. For example: If you're using ZEROFILL on a column that is set to INT(5) and the number 78 is inserted, MySQL will pad that value with zeros until the number satisfies the number in brackets. i.e. 78 will become 00078 and 127 will become 00127. To sum it up: The number in brackets is used for display purposes.
In a way, the number in brackets is kind of usless unless you're using the ZEROFILL attribute.

So the size for the int would remain same i.e., -2147483648 to 2147483648 for signed and 0 to 4294967295 for unsigned (~ 2.15 billions and 4.2 billions, which is one of the reasons why developers remain unaware of the story behind the Number N in parentheses, as it hardly affects the database unless it contains over 2 billions of rows), and in terms of bytes it would be 4 bytes.

For more information on Integer Types size/range, refer to MySQL Manual

From http://redis.io/topics/quickstart

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make redis-cli
sudo cp src/redis-cli /usr/local/bin/

With Docker I normally use https://registry.hub.docker.com/_/redis/. If I need to add redis-cli to an image I use the following snippet.

RUN cd /tmp &&\
    curl http://download.redis.io/redis-stable.tar.gz | tar xz &&\
    make -C redis-stable &&\
    cp redis-stable/src/redis-cli /usr/local/bin &&\
    rm -rf /tmp/redis-stable

In my case I didn't add the http:// prefix. Potentially worth checking.

Make sure there are no 'echo off' statements in the scripts and call 'echo on' after calling each script to reset any you have missed.

The reason is that if echo is left on, then the command interpreter will output each command (after parameter processing) before executing it. Makes it look really bad for using in production, but very useful for debugging purposes as you can see where output has gone wrong.

Also, make sure you are checking the ErrorLevels set by the called batch scripts and programs. Remember that there are 2 different methods used in .bat files for this. If you called a program, the Error level is in %ERRORLEVEL%, while from batch files the error level is returned in the ErrorLevel variable and doesn't need %'s around it.

Junit Rules work on the principle of AOP (aspect oriented programming). It intercepts the test method thus providing an opportunity to do some stuff before or after the execution of a particular test method.

Take the example of the below code:

public class JunitRuleTest {

  @Rule
  public TemporaryFolder tempFolder = new TemporaryFolder();

  @Test
  public void testRule() throws IOException {
    File newFolder = tempFolder.newFolder("Temp Folder");
    assertTrue(newFolder.exists());
  }
} 

Every time the above test method is executed, a temporary folder is created and it gets deleted after the execution of the method. This is an example of an out-of-box rule provided by Junit.

Similar behaviour can also be achieved by creating our own rules. Junit provides the TestRule interface, which can be implemented to create our own Junit Rule.

Here is a useful link for reference:

If you are hosting your react app on IIS, just add a web.config file containing :

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Replace">
        <remove statusCode="404" subStatusCode="-1" />
        <error statusCode="404" path="/" responseMode="ExecuteURL" />
    </httpErrors>
  </system.webServer>
</configuration>

This will tell IIS server to return the main page to the client instead of 404 error and no need to use hash history.

You could use this code:

abc_KeyDown(abc, new KeyEventArgs(Keys.Enter));

In your class AutoMapper profile, you need to create a map for your entity and viewmodel.

ViewModel To Domain Model Mappings:

This is usually in AutoMapper/DomainToViewModelMappingProfile

In Configure(), add a line like

Mapper.CreateMap<YourEntityViewModel, YourEntity>();

Domain Model To ViewModel Mappings:

In ViewModelToDomainMappingProfile, add:

Mapper.CreateMap<YourEntity, YourEntityViewModel>();

An alternative solution, which is portable and with higher precision, available since C++11, is to use std::chrono.

Here is an example:

#include <iostream>
#include <chrono>
typedef std::chrono::high_resolution_clock Clock;

int main()
{
    auto t1 = Clock::now();
    auto t2 = Clock::now();
    std::cout << "Delta t2-t1: " 
              << std::chrono::duration_cast<std::chrono::nanoseconds>(t2 - t1).count()
              << " nanoseconds" << std::endl;
}

Running this on ideone.com gave me:

Delta t2-t1: 282 nanoseconds

I don't know if this is right or wrong, but I pushed the "old name" of the branch to the "new name" of the branch, then deleted the old branch entirely with the following two lines:

git push origin old_branch:new_branch
git push origin :old_branch

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file

"compilerOptions": {
    "noUnusedLocals": true,
    "noUnusedParameters": true
}

have the typescript compiler installed, ifnot install it with:

npm install -g typescript

and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.

I would also recomend using typescript hero extension for organizing your imports.

In order to embed your channel, all you need to do is copy then paste the following code in another web-page.

<script src="http://www.gmodules.com/ig/ifr?url=http://www.google.com/ig/modules/youtube.xml&up_channel=YourChannelName&synd=open&w=320&h=390&title=&border=%23ffffff%7C3px%2C1px+solid+%23999999&output=js"></script>

Make sure to replace the YourChannelName with your actual channel name.

For example: if your channel name were CaliChick94066 your channel embed code would be:

<script src="http://www.gmodules.com/ig/ifr?url=http://www.google.com/ig/modules/youtube.xml&up_channel=CaliChick94066&synd=open&w=320&h=390&title=&border=%23ffffff%7C3px%2C1px+solid+%23999999&output=js"></script>

Please look at the following links:

Embed YouTube Channel

You just have to name the URL to your channel name. Also you can play with the height and the border color and size. Hope it helps

Since the page you load inside the iframe can execute the "break out" code with a setInterval, onbeforeunload might not be that practical, since it could flud the user with 'Are you sure you want to leave?' dialogs.

There is also the iframe security attribute which only works on IE & Opera

:(

In reference to Anthony’s solution, here is a function to get the path:

function circlePath(cx, cy, r){
    return 'M '+cx+' '+cy+' m -'+r+', 0 a '+r+','+r+' 0 1,0 '+(r*2)+',0 a '+r+','+r+' 0 1,0 -'+(r*2)+',0';
}

=Join(Parameters!Product.Label, vbcrfl) for new line

In addition to the nested scrolling NestedScrollView added one major functionality, which could even make it interesting outside of nested contexts: It has build in support for OnScrollChangeListener. Adding a OnScrollChangeListener to the original ScrollView below API 23 required subclassing ScrollView or messing around with the ViewTreeObserver of the ScrollView which often means even more work than subclassing. With NestedScrollView it can be done using the build-in setter.

You can use the inline-block value for display, however in this case you will loose the block feature of h1 i.e. the siblings will be displayed inline with h1 if they are inline elements(in which case you can use a line-break
).

display:inline-block; 

A simple trick that works fine for me to prevent conflicts between older and newer javascript files. That means: If there is a conflict and some error occurs, the user will be prompted to press Ctrl-F5.

At the top of the page add something like

<h1 id="welcome"> Welcome to this page <span style="color:red">... press Ctrl-F5</span></h1>

looking like

Let this line of javascript be the last to be executed when loading the page:

document.getElementById("welcome").innerHTML = "Welcome to this page"

In case that no error occurs the welcome greeting above will hardly be visible and almost immediately be replaced by

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

This kind of error usually means that some parts of (JS) code were not loaded. That the state which is inside of ui-sref is missing.

There is a working example

I am not an expert in ionic, so this example should show that it would be working, but I used some more tricks (parent for tabs)

This is a bit adjusted state def:

.config(function($stateProvider, $urlRouterProvider){
  $urlRouterProvider.otherwise("/index.html");

    $stateProvider

    .state('app', {
      abstract: true,
      templateUrl: "tpl.menu.html",
    })

  $stateProvider.state('index', {
    url: '/',
    templateUrl: "tpl.index.html",
    parent: "app",
  });


  $stateProvider.state('register', {
    url: "/register",
    templateUrl: "tpl.register.html",
    parent: "app",
  });

  $urlRouterProvider.otherwise('/');
}) 

And here we have the parent view with tabs, and their content:

<ion-tabs class="tabs-icon-top">

  <ion-tab title="Index" icon="icon ion-home" ui-sref="index">
    <ion-nav-view name=""></ion-nav-view>
  </ion-tab>

  <ion-tab title="Register" icon="icon ion-person" ui-sref="register">
    <ion-nav-view name=""></ion-nav-view>
  </ion-tab>

</ion-tabs>

Take it more than an example of how to make it running and later use ionic framework the right way...Check that example here

Here is similar Q & A with an example using the named views (for sure better solution) ionic routing issue, shows blank page

Improved version with named views in a tab is here: http://plnkr.co/edit/Mj0rUxjLOXhHIelt249K?p=preview

  <ion-tab title="Index" icon="icon ion-home" ui-sref="index">
    <ion-nav-view name="index"></ion-nav-view>
  </ion-tab>

  <ion-tab title="Register" icon="icon ion-person" ui-sref="register">
    <ion-nav-view name="register"></ion-nav-view>
  </ion-tab>

targeting named views:

  $stateProvider.state('index', {
    url: '/',
    views: { "index" : { templateUrl: "tpl.index.html" } },
    parent: "app",
  });


  $stateProvider.state('register', {
    url: "/register",
    views: { "register" : { templateUrl: "tpl.register.html", } },
    parent: "app",
  });

eval should do it.

eval(s);

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

On the CREATE TABLE,

The AUTO_INCREMENT of abuse_id is set to 2. MySQL now thinks 1 already exists.

With the INSERT statement you are trying to insert abuse_id with record 1. Please set AUTO_INCREMENT on CREATE_TABLE to 1 and try again.

Otherwise set the abuse_id in the INSERT statement to 'NULL'.

How can i resolve this?

Here is a nice explanation of update operation with some examples. Although it is Postgres site, but the SQL queries are valid for the other DBs, too. The following examples are intuitive to understand.

-- Update contact names in an accounts table to match the currently assigned salesmen:

UPDATE accounts SET (contact_first_name, contact_last_name) =
    (SELECT first_name, last_name FROM salesmen
     WHERE salesmen.id = accounts.sales_id);

-- A similar result could be accomplished with a join:

UPDATE accounts SET contact_first_name = first_name,
                    contact_last_name = last_name
  FROM salesmen WHERE salesmen.id = accounts.sales_id;

However, the second query may give unexpected results if salesmen.id is not a unique key, whereas the first query is guaranteed to raise an error if there are multiple id matches. Also, if there is no match for a particular accounts.sales_id entry, the first query will set the corresponding name fields to NULL, whereas the second query will not update that row at all.

Hence for the given example, the most reliable query is like the following.

UPDATE tempDataView SET (marks) =
    (SELECT marks FROM tempData
     WHERE tempDataView.Name = tempData.Name);

Reading between the lines - Is this an innodb database? In which case the actual data is normally stored in that directory under the name ibdata1. This file contains all your tables unless you specifically set up mysql to use one-file-per-table (innodb-file-per-table)

<form>
  <label for="company">
    <span>Company Name</span>
    <input type="text" id="company" />
  </label>
  <label for="contact">
    <span>Contact Name</span>
    <input type="text" id="contact" />
  </label>
</form>

span { display: block; margin: 0 0 3px; font-size: 1.2em; font-weight: bold; }

I just set JAVA_HOME to the output of that command, which should give you the Java path specified in your Java preferences. Here's a snippet from my .bashrc file, which sets this variable:

export JAVA_HOME=$(/usr/libexec/java_home)

I haven't experienced any problems with that technique.

Occasionally I do have to change the value of JAVA_HOME to an earlier version of Java. For example, one program I'm maintaining requires 32-bit Java 5 on OS X, so when using that program, I set JAVA_HOME by running:

export JAVA_HOME=$(/usr/libexec/java_home -v 1.5)

For those of you who don't have java_home in your path add it like this.

sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home /usr/libexec/java_home

You're correct in that, semantically, ref provides both "in" and "out" functionality, whereas out only provides "out" functionality. There are some things to consider:

1. out requires that the method accepting the parameter MUST, at some point before returning, assign a value to the variable. You find this pattern in some of the key/value data storage classes like Dictionary<K,V>, where you have functions like TryGetValue. This function takes an out parameter that holds what the value will be if retrieved. It wouldn't make sense for the caller to pass a value into this function, so out is used to guarantee that some value will be in the variable after the call, even if it isn't "real" data (in the case of TryGetValue where the key isn't present).
2. out and ref parameters are marshaled differently when dealing with interop code

Also, as an aside, it's important to note that while reference types and value types differ in the nature of their value, every variable in your application points to a location of memory that holds a value, even for reference types. It just happens that, with reference types, the value contained in that location of memory is another memory location. When you pass values to a function (or do any other variable assignment), the value of that variable is copied into the other variable. For value types, that means that the entire content of the type is copied. For reference types, that means that the memory location is copied. Either way, it does create a copy of the data contained in the variable. The only real relevance that this holds deals with assignment semantics; when assigning a variable or passing by value (the default), when a new assignment is made to the original (or new) variable, it does not affect the other variable. In the case of reference types, yes, changes made to the instance are available on both sides, but that's because the actual variable is just a pointer to another memory location; the content of the variable--the memory location--didn't actually change.

Passing with the ref keyword says that both the original variable and the function parameter will actually point to the same memory location. This, again, affects only assignment semantics. If a new value is assigned to one of the variables, then because the other points to the same memory location the new value will be reflected on the other side.

The question is asked in a misleading manner. "Removing the selected attribute" and "deselecting all options" are entirely different things.

To deselect all options in a documented, cross-browser manner use either

$("select").val([]);

or

// Note the use of .prop instead of .attr
$("select option").prop("selected", false);

A reset button doesn't need any script at all (or name or id):

<input type="reset">

and you're done. But if you really must use script, note that every form control has a form property that references the form it's in, so you could do:

<input type="button" onclick="this.form.reset();">

But a reset button is a far better choice.

I must clarify that no-cache does not mean do not cache. In fact, it means "revalidate with server" before using any cached response you may have, on every request.

must-revalidate, on the other hand, only needs to revalidate when the resource is considered stale.

If the server says that the resource is still valid then the cache can respond with its representation, thus alleviating the need for the server to resend the entire resource.

no-store is effectively the full do not cache directive and is intended to prevent storage of the representation in any form of cache whatsoever.

I say whatsoever, but note this in the RFC 2616 HTTP spec:

History buffers MAY store such responses as part of their normal operation

But this is omitted from the newer RFC 7234 HTTP spec in potentially an attempt to make no-store stronger, see:

http://tools.ietf.org/html/rfc7234#section-5.2.1.5

You don't need any jQuery specific code to handle this. Just use a RegExp to replace them:

$("#a").className = $("#a").className.replace(/\bbg.*?\b/g, '');

You can modify this to support any prefix but the faster method is above as the RegExp will be compiled only once:

function removeClassByPrefix(el, prefix) {
    var regx = new RegExp('\\b' + prefix + '.*?\\b', 'g');
    el.className = el.className.replace(regx, '');
    return el;
}

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}
