@JoeSchr has an answer. Here is another way to do if you don't want deep: true

 mounted() {
    this.yourMethod();
    // re-render any time a prop changes
    Object.keys(this.$options.props).forEach(key => {
      this.$watch(key, this.yourMethod);
    });
  },

Use:

subA.tick_params(labelsize=6)

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

The string ctor is suitable for this conversion:

System.out.println("string " + new String(new byte[] {0x63}));

If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json

Json(someDictionaryObj, JsonRequestBehavior.AllowGet);

Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5

as for your web request...it seems ok at first glance..

I would use something like this..

public void WebRequestinJson(string url, string postData)
    {
    StreamWriter requestWriter;

    var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
    if (webRequest != null)
    {
        webRequest.Method = "POST";
        webRequest.ServicePoint.Expect100Continue = false;
        webRequest.Timeout = 20000;

        webRequest.ContentType = "application/json";
        //POST the data.
        using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }
    }
}

May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.

Assuming this branch isn't an external or a symlink, removing the branch should be as simple as:

svn rm branches/< mybranch >

svn ci -m "message"

If you'd like to do this in the repository then update to remove it from your working copy you can do something like:

svn rm http://< myurl >/< myrepo >/branches/< mybranch >

Then run:

The simplest solution might be to limit the number of characters in the HTML itself. Rails has a truncate(string, length) helper, and I'm certain that whichever backend you're using provides something similar.

Due to the cross-browser issues you're already familiar with regarding the width of select boxes, this seems to me to be the most straightforward and least error-prone option.

<select>
  <option value="1">One</option>
  <option value="100">One hund...</option>
<select>

I think much confusion is generated by not communicating what is meant by passed by reference. When some people say pass by reference they usually mean not the argument itself, but rather the object being referenced. Some other say that pass by reference means that the object can't be changed in the callee. Example:

struct Object {
    int i;
};

void sample(Object* o) { // 1
    o->i++;
}

void sample(Object const& o) { // 2
    // nothing useful here :)
}

void sample(Object & o) { // 3
    o.i++;
}

void sample1(Object o) { // 4
    o.i++;
}

int main() {
    Object obj = { 10 };
    Object const obj_c = { 10 };

    sample(&obj); // calls 1
    sample(obj) // calls 3
    sample(obj_c); // calls 2
    sample1(obj); // calls 4
}

Some people would claim that 1 and 3 are pass by reference, while 2 would be pass by value. Another group of people say all but the last is pass by reference, because the object itself is not copied.

I would like to draw a definition of that here what i claim to be pass by reference. A general overview over it can be found here: Difference between pass by reference and pass by value. The first and last are pass by value, and the middle two are pass by reference:

    sample(&obj);
       // yields a `Object*`. Passes a *pointer* to the object by value. 
       // The caller can change the pointer (the parameter), but that 
       // won't change the temporary pointer created on the call side (the argument). 

    sample(obj)
       // passes the object by *reference*. It denotes the object itself. The callee
       // has got a reference parameter.

    sample(obj_c);
       // also passes *by reference*. the reference parameter references the
       // same object like the argument expression. 

    sample1(obj);
       // pass by value. The parameter object denotes a different object than the 
       // one passed in.

I vote for the following definition:

An argument (1.3.1) is passed by reference if and only if the corresponding parameter of the function that's called has reference type and the reference parameter binds directly to the argument expression (8.5.3/4). In all other cases, we have to do with pass by value.

That means that the following is pass by value:

void f1(Object const& o);
f1(Object()); // 1

void f2(int const& i);
f2(42); // 2

void f3(Object o);
f3(Object());     // 3
Object o1; f3(o1); // 4

void f4(Object *o);
Object o1; f4(&o1); // 5

1 is pass by value, because it's not directly bound. The implementation may copy the temporary and then bind that temporary to the reference. 2 is pass by value, because the implementation initializes a temporary of the literal and then binds to the reference. 3 is pass by value, because the parameter has not reference type. 4 is pass by value for the same reason. 5 is pass by value because the parameter has not got reference type. The following cases are pass by reference (by the rules of 8.5.3/4 and others):

void f1(Object *& op);
Object a; Object *op1 = &a; f1(op1); // 1

void f2(Object const& op);
Object b; f2(b); // 2

struct A { };
struct B { operator A&() { static A a; return a; } };
void f3(A &);
B b; f3(b); // passes the static a by reference

At my work we have our restful services on a different port number and the data resides in db2 on a pair of AS400s. We typically use the $.getJSON AJAX method because it easily returns JSONP using the ?callback=? without having any issues with CORS.

data ='USER=<?echo trim($USER)?>' +
         '&QRYTYPE=' + $("input[name=QRYTYPE]:checked").val();

        //Call the REST program/method returns: JSONP 
        $.getJSON( "http://www.stackoverflow.com/rest/resttest?callback=?",data)
        .done(function( json ) {        

              //  loading...
                if ($.trim(json.ERROR) != '') {
                    $("#error-msg").text(message).show();
                }
                else{
                    $(".error").hide();
                    $("#jsonp").text(json.whatever);

                }

        })  
        .fail(function( jqXHR, textStatus, error ) {
        var err = textStatus + ", " + error;
        alert('Unable to Connect to Server.\n Try again Later.\n Request Failed: ' + err);
        });     

None of the answers worked for me. If you are running on Ubuntu, you can try:

With python3:

sudo apt-get install python3 python-dev python3-dev \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

With Python 2:

sudo apt-get install python-dev  \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

Using regular expression is better.

str.matches("-?\\d+");


-?     --> negative sign, could have none or one
\\d+   --> one or more digits

It is not good to use NumberFormatException here if you can use if-statement instead.

If you don't want leading zero's, you can just use the regular expression as follow:

str.matches("-?(0|[1-9]\\d*)");

Here's what I ended up using.

I'm very new to AngularJS, so would love to see better / alternative solutions.

angular.module('formComponents', [])
    .directive('formInput', function() {
        return {
            restrict: 'E',
            scope: {},
            link: function(scope, element, attrs)
            {
                var type = attrs.type || 'text';
                var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
                var htmlText = '<div class="control-group">' +
                    '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                        '<div class="controls">' +
                        '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                        '</div>' +
                    '</div>';
                element.html(htmlText);
            }
        }
    })

Example usage:

<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>

Consider using a the transform: rotate(-90deg) style on an element. See http://www.w3schools.com/cssref/css3_pr_transform.asp

Example, In your css

.verticaltext_content {
  position: relative;
  transform: rotate(-90deg);
  right:90px;   //These three positions need adjusting
  bottom:150px; //based on your actual chart size
  width:200px;
}

Add a space fudge factor to the Y Axis scale so the text has room to render in your javascript.

scaleLabel: "      <%=value%>"

Then in your html after your chart canvas put something like...

<div class="text-center verticaltext_content">Y Axis Label</div>

It is not the most elegant solution, but worked well when I had a few layers between the html and the chart code (using angular-chart and not wanting to change any source code).

converting object id to string(using toString() method) will do the job.

Here's a simple single line alternative for users who don't have the watch command who want to execute a command every 3 seconds:

while :; do your-command; sleep 3; done

It's an infinite loop that is basically the same as doing the following:

watch -n3 your-command

Try this one

var getValue = cmd.ExecuteScalar();    
conn.Close();
return (getValue == null) ? string.Empty : getValue.ToString();

The static one is the same member on all of the class instances and the class itself.
The non-static is one for every instance (object), so in your exact case it's a waste of memory if you don't put static.

You don't declare anything in Python. You just use it. I recommend you start out with something like http://diveintopython.net.

You can't exclude patterns with the glob function, globs only allow for inclusion patterns. Globbing syntax is very limited (even a [!..] character class must match a character, so it is an inclusion pattern for every character that is not in the class).

You'll have to do your own filtering; a list comprehension usually works nicely here:

files = [fn for fn in glob('somepath/*.txt') 
         if not os.path.basename(fn).startswith('eph')]

The element has both an attribute and a property named checked. The property determines the current state.

The attribute is a string, and the property is a boolean. When the element is created from the HTML code, the attribute is set from the markup, and the property is set depending on the value of the attribute.

If there is no value for the attribute in the markup, the attribute becomes null, but the property is always either true or false, so it becomes false.

When you set the property, you should use a boolean value:

document.getElementById('myRadio').checked = true;

If you set the attribute, you use a string:

document.getElementById('myRadio').setAttribute('checked', 'checked');

Note that setting the attribute also changes the property, but setting the property doesn't change the attribute.

Note also that whatever value you set the attribute to, the property becomes true. Even if you use an empty string or null, setting the attribute means that it's checked. Use removeAttribute to uncheck the element using the attribute:

document.getElementById('myRadio').removeAttribute('checked');

Use history.pushState() from the HTML 5 History API.

Refer to the HTML5 History API for more details.

It's entirely likely that a large portion of the developer base comes from a Java background where using == to compare strings is wrong and doesn't work.

In C# there's no (practical) difference (for strings) as long as they are typed as string.

If they are typed as object or T then see other answers here that talk about generic methods or operator overloading as there you definitely want to use the Equals method.

Here's a tutorial about ordering objects:

• The Java Tutorials - Collections - Object Ordering

Although I will give some examples, I would recommend to read it anyway.

There are various way to sort an ArrayList. If you want to define a natural (default) ordering, then you need to let Contact implement Comparable. Assuming that you want to sort by default on name, then do (nullchecks omitted for simplicity):

public class Contact implements Comparable<Contact> {

    private String name;
    private String phone;
    private Address address;

    @Override
    public int compareTo(Contact other) {
        return name.compareTo(other.name);
    }

    // Add/generate getters/setters and other boilerplate.
}

so that you can just do

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

Collections.sort(contacts);

If you want to define an external controllable ordering (which overrides the natural ordering), then you need to create a Comparator:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Now sort by address instead of name (default).
Collections.sort(contacts, new Comparator<Contact>() {
    public int compare(Contact one, Contact other) {
        return one.getAddress().compareTo(other.getAddress());
    }
}); 

You can even define the Comparators in the Contact itself so that you can reuse them instead of recreating them everytime:

public class Contact {

    private String name;
    private String phone;
    private Address address;

    // ...

    public static Comparator<Contact> COMPARE_BY_PHONE = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.phone.compareTo(other.phone);
        }
    };

    public static Comparator<Contact> COMPARE_BY_ADDRESS = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.address.compareTo(other.address);
        }
    };

}

which can be used as follows:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Sort by address.
Collections.sort(contacts, Contact.COMPARE_BY_ADDRESS);

// Sort later by phone.
Collections.sort(contacts, Contact.COMPARE_BY_PHONE);

And to cream the top off, you could consider to use a generic javabean comparator:

public class BeanComparator implements Comparator<Object> {

    private String getter;

    public BeanComparator(String field) {
        this.getter = "get" + field.substring(0, 1).toUpperCase() + field.substring(1);
    }

    public int compare(Object o1, Object o2) {
        try {
            if (o1 != null && o2 != null) {
                o1 = o1.getClass().getMethod(getter, new Class[0]).invoke(o1, new Object[0]);
                o2 = o2.getClass().getMethod(getter, new Class[0]).invoke(o2, new Object[0]);
            }
        } catch (Exception e) {
            // If this exception occurs, then it is usually a fault of the developer.
            throw new RuntimeException("Cannot compare " + o1 + " with " + o2 + " on " + getter, e);
        }

        return (o1 == null) ? -1 : ((o2 == null) ? 1 : ((Comparable<Object>) o1).compareTo(o2));
    }

}

which you can use as follows:

// Sort on "phone" field of the Contact bean.
Collections.sort(contacts, new BeanComparator("phone"));

(as you see in the code, possibly null fields are already covered to avoid NPE's during sort)

Consider also .attr()

$("#roommate_but").attr("disabled", true); worked for me.

The requests library has a simpler interface and works with both Python 2 and 3.

import requests

response = requests.get(target_url)
data = response.text

You can use a RegExp to replace all the non-digit characters:

var myString = 'abc123.8<blah>';
myString = myString.replace(/[^\d]/g, ''); // 1238

If you want to see which IP addresses are in use on a specific subnet then there are several different IP Address managers.

Try Angry IP Scanner or Solarwinds or Advanced IP Scanner

In Firefox at least, the DOM inspector is telling me that the File input elements have a property called files. You should be able to check its length.

document.getElementById('myFileInput').files.length

I needed time only up to one day, 24h, this was my take:

const milliseconds = 5680000;_x000D_
_x000D_
const hours = `0${new Date(milliseconds).getHours() - 1}`.slice(-2);_x000D_
const minutes = `0${new Date(milliseconds).getMinutes()}`.slice(-2);_x000D_
const seconds = `0${new Date(milliseconds).getSeconds()}`.slice(-2);_x000D_
_x000D_
const time = `${hours}:${minutes}:${seconds}`_x000D_
console.log(time);

you could get days this way as well if needed.

To check if a directory exists in a shell script, you can use the following:

if [ -d "$DIRECTORY" ]; then
  # Control will enter here if $DIRECTORY exists.
fi

Or to check if a directory doesn't exist:

if [ ! -d "$DIRECTORY" ]; then
  # Control will enter here if $DIRECTORY doesn't exist.
fi

However, as Jon Ericson points out, subsequent commands may not work as intended if you do not take into account that a symbolic link to a directory will also pass this check. E.g. running this:

ln -s "$ACTUAL_DIR" "$SYMLINK"
if [ -d "$SYMLINK" ]; then 
  rmdir "$SYMLINK" 
fi

Will produce the error message:

rmdir: failed to remove `symlink': Not a directory

So symbolic links may have to be treated differently, if subsequent commands expect directories:

if [ -d "$LINK_OR_DIR" ]; then 
  if [ -L "$LINK_OR_DIR" ]; then
    # It is a symlink!
    # Symbolic link specific commands go here.
    rm "$LINK_OR_DIR"
  else
    # It's a directory!
    # Directory command goes here.
    rmdir "$LINK_OR_DIR"
  fi
fi

Take particular note of the double-quotes used to wrap the variables. The reason for this is explained by 8jean in another answer.

If the variables contain spaces or other unusual characters it will probably cause the script to fail.

You can use SelectionChanged event since you are using FullRowSelect selection mode. Than inside the handler you can access SelectedRows property and get data from it. Example:

private void dataGridView_SelectionChanged(object sender, EventArgs e) 
{
    foreach (DataGridViewRow row in dataGridView.SelectedRows) 
    {
        string value1 = row.Cells[0].Value.ToString();
        string value2 = row.Cells[1].Value.ToString();
        //...
    }
}

You can also walk through the column collection instead of typing indexes...

I don't think it is possible using just HTML. However using javascript this should be doable. Bassicly we loop over each image, test if it is complete and if it's naturalWidth is zero then that means that it not found. Here is the code:

fixBrokenImages = function( url ){
    var img = document.getElementsByTagName('img');
    var i=0, l=img.length;
    for(;i<l;i++){
        var t = img[i];
        if(t.naturalWidth === 0){
            //this image is broken
            t.src = url;
        }
    }
}

Use it like this:

 window.onload = function() {
    fixBrokenImages('example.com/image.png');
 }

To get it so that it can be loaded sensibly by Excel, you need to use a comma (the csv default) as the delimiter, unless you are in a locale (e.g. Europe) where you need a semicolon.

If you want you can use numpy's save function to save the list as file. Say you have two lists

sampleList1=['z','x','a','b']
sampleList2=[[1,2],[4,5]]

here's the function to save the list as file, remember you need to keep the extension .npy

def saveList(myList,filename):
    # the filename should mention the extension 'npy'
    np.save(filename,myList)
    print("Saved successfully!")

and here's the function to load the file into a list

def loadList(filename):
    # the filename should mention the extension 'npy'
    tempNumpyArray=np.load(filename)
    return tempNumpyArray.tolist()

a working example

>>> saveList(sampleList1,'sampleList1.npy')
>>> Saved successfully!
>>> saveList(sampleList2,'sampleList2.npy')
>>> Saved successfully!

# loading the list now 
>>> loadedList1=loadList('sampleList1.npy')
>>> loadedList2=loadList('sampleList2.npy')

>>> loadedList1==sampleList1
>>> True

>>> print(loadedList1,sampleList1)

>>> ['z', 'x', 'a', 'b'] ['z', 'x', 'a', 'b']

I've ran into the same issue and these two links solved for me:

The first one is this one: How do I retrieve the logged in Google account on android phones?

Which presents the code for retrieving the accounts associated with the phone. Basically you will need something like this:

AccountManager manager = (AccountManager) getSystemService(ACCOUNT_SERVICE);
Account[] list = manager.getAccounts();

And to add the permissions in the AndroidManifest.xml

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

Additionally, if you are using the Emulator the following link will help you to set it up with an account : Android Emulator - Trouble creating user accounts

Basically, it says that you must create an android device based on a API Level and not the SDK Version (like is usually done).

Do NOT loop through all cells!! There is a lot of overhead in communications between worksheets and VBA, for both reading and writing. Looping through all cells will be agonizingly slow. I'm talking hours.

Instead, load an entire sheet at once into a Variant array. In Excel 2003, this takes about 2 seconds (and 250 MB of RAM). Then you can loop through it in no time at all.

In Excel 2007 and later, sheets are about 1000 times larger (1048576 rows × 16384 columns = 17 billion cells, compared to 65536 rows × 256 columns = 17 million in Excel 2003). You will run into an "Out of memory" error if you try to load the whole sheet into a Variant; on my machine I can only load 32 million cells at once. So you have to limit yourself to the range you know has actual data in it, or load the sheet bit by bit, e.g. 30 columns at a time.

Option Explicit

Sub test()

    Dim varSheetA As Variant
    Dim varSheetB As Variant
    Dim strRangeToCheck As String
    Dim iRow As Long
    Dim iCol As Long

    strRangeToCheck = "A1:IV65536"
    ' If you know the data will only be in a smaller range, reduce the size of the ranges above.
    Debug.Print Now
    varSheetA = Worksheets("Sheet1").Range(strRangeToCheck)
    varSheetB = Worksheets("Sheet2").Range(strRangeToCheck) ' or whatever your other sheet is.
    Debug.Print Now

    For iRow = LBound(varSheetA, 1) To UBound(varSheetA, 1)
        For iCol = LBound(varSheetA, 2) To UBound(varSheetA, 2)
            If varSheetA(iRow, iCol) = varSheetB(iRow, iCol) Then
                ' Cells are identical.
                ' Do nothing.
            Else
                ' Cells are different.
                ' Code goes here for whatever it is you want to do.
            End If
        Next iCol
    Next iRow

End Sub

To compare to a sheet in a different workbook, open that workbook and get the sheet as follows:

Set wbkA = Workbooks.Open(filename:="C:\MyBook.xls")
Set varSheetA = wbkA.Worksheets("Sheet1") ' or whatever sheet you need

If you are using .net core, then during development you can bypass certificate validation by using compiler directives. This way will only validate certificate for release and not for debug:

#if (DEBUG)
        client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
                new X509ServiceCertificateAuthentication()
                {
                    CertificateValidationMode = X509CertificateValidationMode.None,
                    RevocationMode = System.Security.Cryptography.X509Certificates.X509RevocationMode.NoCheck
                };   #endif

JSON string that needs to be deserialized will have to contain the type information about parameter T.
You will have to put Jackson annotations on every class that can be passed as parameter T to class Data so that the type information about parameter type T can be read from / written to JSON string by Jackson.

Let us assume that T can be any class that extends abstract class Result.

class Data <T extends Result> {
    int found;
    Class<T> hits
}

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT)
@JsonSubTypes({
        @JsonSubTypes.Type(value = ImageResult.class, name = "ImageResult"),
        @JsonSubTypes.Type(value = NewsResult.class, name = "NewsResult")})
public abstract class Result {

}

public class ImageResult extends Result {

}

public class NewsResult extends Result {

}

Once each of the class (or their common supertype) that can be passed as parameter T is annotated, Jackson will include information about parameter T in the JSON. Such JSON can then be deserialized without knowing the parameter T at compile time.
This Jackson documentation link talks about Polymorphic Deserialization but is useful to refer to for this question as well.

Generally you don't kill, stop, or interrupt a thread (or check wheter it is interrupted()), but let it terminate naturally.

It is simple. You can use any loop together with (volatile) boolean variable inside run() method to control thread's activity. You can also return from active thread to the main thread to stop it.

This way you gracefully kill a thread :) .

For this you can use CSS3 background-size property. Write like this:

#div2{
    background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
    -moz-background-size:100% 100%;
    -webkit-background-size:100% 100%;
    background-size:100% 100%;
    height:180px;
    width:200px;
    border: 1px solid red;
}

Inspired by @hgoebl's answer. His code is for UTF-16 and I needed something for US-ASCII. So here's a more complete answer covering US-ASCII, UTF-16, and UTF-32.

/**@returns {Array} bytes of US-ASCII*/
function stringToAsciiByteArray(str)
{
    var bytes = [];
   for (var i = 0; i < str.length; ++i)
   {
       var charCode = str.charCodeAt(i);
      if (charCode > 0xFF)  // char > 1 byte since charCodeAt returns the UTF-16 value
      {
          throw new Error('Character ' + String.fromCharCode(charCode) + ' can\'t be represented by a US-ASCII byte.');
      }
       bytes.push(charCode);
   }
    return bytes;
}
/**@returns {Array} bytes of UTF-16 Big Endian without BOM*/
function stringToUtf16ByteArray(str)
{
    var bytes = [];
    //currently the function returns without BOM. Uncomment the next line to change that.
    //bytes.push(254, 255);  //Big Endian Byte Order Marks
   for (var i = 0; i < str.length; ++i)
   {
       var charCode = str.charCodeAt(i);
       //char > 2 bytes is impossible since charCodeAt can only return 2 bytes
       bytes.push((charCode & 0xFF00) >>> 8);  //high byte (might be 0)
       bytes.push(charCode & 0xFF);  //low byte
   }
    return bytes;
}
/**@returns {Array} bytes of UTF-32 Big Endian without BOM*/
function stringToUtf32ByteArray(str)
{
    var bytes = [];
    //currently the function returns without BOM. Uncomment the next line to change that.
    //bytes.push(0, 0, 254, 255);  //Big Endian Byte Order Marks
   for (var i = 0; i < str.length; i+=2)
   {
       var charPoint = str.codePointAt(i);
       //char > 4 bytes is impossible since codePointAt can only return 4 bytes
       bytes.push((charPoint & 0xFF000000) >>> 24);
       bytes.push((charPoint & 0xFF0000) >>> 16);
       bytes.push((charPoint & 0xFF00) >>> 8);
       bytes.push(charPoint & 0xFF);
   }
    return bytes;
}

UTF-8 is variable length and isn't included because I would have to write the encoding myself. UTF-8 and UTF-16 are variable length. UTF-8, UTF-16, and UTF-32 have a minimum number of bits as their name indicates. If a UTF-32 character has a code point of 65 then that means there are 3 leading 0s. But the same code for UTF-16 has only 1 leading 0. US-ASCII on the other hand is fixed width 8-bits which means it can be directly translated to bytes.

String.prototype.charCodeAt returns a maximum number of 2 bytes and matches UTF-16 exactly. However for UTF-32 String.prototype.codePointAt is needed which is part of the ECMAScript 6 (Harmony) proposal. Because charCodeAt returns 2 bytes which is more possible characters than US-ASCII can represent, the function stringToAsciiByteArray will throw in such cases instead of splitting the character in half and taking either or both bytes.

Note that this answer is non-trivial because character encoding is non-trivial. What kind of byte array you want depends on what character encoding you want those bytes to represent.

javascript has the option of internally using either UTF-16 or UCS-2 but since it has methods that act like it is UTF-16 I don't see why any browser would use UCS-2. Also see: https://mathiasbynens.be/notes/javascript-encoding

Yes I know the question is 4 years old but I needed this answer for myself.

Sometimes we have an upstream that rebased/rewound a branch we're depending on. This can be a big problem -- causing messy conflicts for us if we're downstream.

The magic is git pull --rebase

A normal git pull is, loosely speaking, something like this (we'll use a remote called origin and a branch called foo in all these examples):

# assume current checked out branch is "foo"
git fetch origin
git merge origin/foo

At first glance, you might think that a git pull --rebase does just this:

git fetch origin
git rebase origin/foo

But that will not help if the upstream rebase involved any "squashing" (meaning that the patch-ids of the commits changed, not just their order).

Which means git pull --rebase has to do a little bit more than that. Here's an explanation of what it does and how.

Let's say your starting point is this:

a---b---c---d---e  (origin/foo) (also your local "foo")

Time passes, and you have made some commits on top of your own "foo":

a---b---c---d---e---p---q---r (foo)

Meanwhile, in a fit of anti-social rage, the upstream maintainer has not only rebased his "foo", he even used a squash or two. His commit chain now looks like this:

a---b+c---d+e---f  (origin/foo)

A git pull at this point would result in chaos. Even a git fetch; git rebase origin/foo would not cut it, because commits "b" and "c" on one side, and commit "b+c" on the other, would conflict. (And similarly with d, e, and d+e).

What git pull --rebase does, in this case, is:

git fetch origin
git rebase --onto origin/foo e foo

This gives you:

 a---b+c---d+e---f---p'---q'---r' (foo)

You may still get conflicts, but they will be genuine conflicts (between p/q/r and a/b+c/d+e/f), and not conflicts caused by b/c conflicting with b+c, etc.

Answer taken from (and slightly modified):
http://gitolite.com/git-pull--rebase

The given answers will only delete files (which admittedly is what is in the title of this post), but here's some code that will first delete all of the files older than 15 days, and then recursively delete any empty directories that may have been left behind. My code also uses the -Force option to delete hidden and read-only files as well. Also, I chose to not use aliases as the OP is new to PowerShell and may not understand what gci, ?, %, etc. are.

$limit = (Get-Date).AddDays(-15)
$path = "C:\Some\Path"

# Delete files older than the $limit.
Get-ChildItem -Path $path -Recurse -Force | Where-Object { !$_.PSIsContainer -and $_.CreationTime -lt $limit } | Remove-Item -Force

# Delete any empty directories left behind after deleting the old files.
Get-ChildItem -Path $path -Recurse -Force | Where-Object { $_.PSIsContainer -and (Get-ChildItem -Path $_.FullName -Recurse -Force | Where-Object { !$_.PSIsContainer }) -eq $null } | Remove-Item -Force -Recurse

And of course if you want to see what files/folders will be deleted before actually deleting them, you can just add the -WhatIf switch to the Remove-Item cmdlet call at the end of both lines.

The code shown here is PowerShell v2.0 compatible, but I also show this code and the faster PowerShell v3.0 code as handy reusable functions on my blog.

I think it is important to consider that, to a browser, 401 initiates an authentication dialog for the user to enter new credentials, while 403 does not. Browsers think that, if a 401 is returned, then the user should re-authenticate. So 401 stands for invalid authentication while 403 stands for a lack of permission.

Here are some cases under that logic where an error would be returned from authentication or authorization, with important phrases bolded.

• A resource requires authentication but no credentials were specified.

401: The client should specify credentials.

• The specified credentials are in an invalid format.

400: That's neither 401 nor 403, as syntax errors should always return 400.

• The specified credentials reference a user which does not exist.

401: The client should specify valid credentials.

• The specified credentials are invalid but specify a valid user (or don't specify a user if a specified user is not required).

401: Again, the client should specify valid credentials.

• The specified credentials have expired.

401: This is practically the same as having invalid credentials in general, so the client should specify valid credentials.

• The specified credentials are completely valid but do not suffice the particular resource, though it is possible that credentials with more permission could.

403: Specifying valid credentials would not grant access to the resource, as the current credentials are already valid but only do not have permission.

• The particular resource is inaccessible regardless of credentials.

403: This is regardless of credentials, so specifying valid credentials cannot help.

• The specified credentials are completely valid but the particular client is blocked from using them.

403: If the client is blocked, specifying new credentials will not do anything.

This is a slight modification from a previous solution. My example looks for stderr redirection in bash scripts: grep '2>' $(find . -name "*.bash")

Another method through re module. It does the reverse operation of matching all the words instead of spitting the whole sentence by space.

>>> import re
>>> s = "many   fancy word \nhello    \thi"
>>> re.findall(r'\S+', s)
['many', 'fancy', 'word', 'hello', 'hi']

Above regex would match one or more non-space characters.

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

You have to modify two possible limits:

In conf\server.xml

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
                maxPostSize="67589953" />

In webapps\manager\WEB-INF\web.xml

<multipart-config>
  <!-- 52MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

Have a look at ?"%in%".

dt[dt$fct %in% vc,]
   fct X
1    a 2
3    c 3
5    c 5
7    a 7
9    c 9
10   a 1
12   c 2
14   c 4

You could also use ?is.element:

dt[is.element(dt$fct, vc),]

To use BeginForm, here's the way to use it:

 using(Html.BeginForm("uploadfiles", 
"home", FormMethod.POST, new Dictionary<string, object>(){{"type", "file"}})

Entity

public class PageEntity
{
    public int Page { get; set; }
    public string Class { get; set; }
}

public class Pagination
{
    public List<PageEntity> Pages { get; set; }
    public int Next { get; set; }
    public int Previous { get; set; }
    public string NextClass { get; set; }
    public string PreviousClass { get; set; }
    public bool Display { get; set; }
    public string Query { get; set; }
}

HTML

<nav>
    <div class="navigation" style="text-align: center">
        <ul class="pagination">
            <li class="page-item @Model.NextClass"><a class="page-link" href="?page=@(@[email protected])">&laquo;</a></li>
            @foreach (var item in @Model.Pages)
            {
                <li class="page-item @item.Class"><a class="page-link" href="?page=@([email protected])">@item.Page</a></li>
            }
            <li class="page-item @Model.NextClass"><a class="page-link" href="?page=@(@[email protected])">&raquo;</a></li>
        </ul>
    </div>
 </nav>

Paging Logic

public Pagination GetCategoryPaging(int currentPage, int recordCount, string query)
{
    string pageClass = string.Empty; int pageSize = 10, innerCount = 5;

    Pagination pagination = new Pagination();
    pagination.Pages = new List<PageEntity>();
    pagination.Next = currentPage + 1;
    pagination.Previous = ((currentPage - 1) > 0) ? (currentPage - 1) : 1;
    pagination.Query = query;

    int totalPages = ((int)recordCount % pageSize) == 0 ? (int)recordCount / pageSize : (int)recordCount / pageSize + 1;

    int loopStart = 1, loopCount = 1;

    if ((currentPage - 2) > 0)
    {
        loopStart = (currentPage - 2);
    }

    for (int i = loopStart; i <= totalPages; i++)
    {
        pagination.Pages.Add(new PageEntity { Page = i, Class = string.Empty });

        if (loopCount == innerCount)
        { break; }

        loopCount++;
    }

    if (totalPages <= innerCount)
    {
        pagination.PreviousClass = "disabled";
    }

    foreach (var item in pagination.Pages.Where(x => x.Page == currentPage))
    {
        item.Class = "active";
    }

    if (pagination.Pages.Count() <= 1)
    {
        pagination.Display = false;
    }

    return pagination;
}

Using Controller

public ActionResult GetPages()
{
    int currentPage = 1; string search = string.Empty;
    if (!string.IsNullOrEmpty(Request.QueryString["page"]))
    {
        currentPage = Convert.ToInt32(Request.QueryString["page"]);
    }

    if (!string.IsNullOrEmpty(Request.QueryString["q"]))
    {
        search = "&q=" + Request.QueryString["q"];
    }
    /* to be Fetched from database using count */
    int recordCount = 100;

    Place place = new Place();
    Pagination pagination = place.GetCategoryPaging(currentPage, recordCount, search);

    return PartialView("Controls/_Pagination", pagination);
}

Here is my use case, which requires an exceptional amount of encoding. Maybe you think it contrived, but we run this on production. Coincidently, this covers every type of encoding, so I'm posting as a tutorial.

Use case description

Somebody just bought a prepaid gift card ("token") on our website. Tokens have corresponding URLs to redeem them. This customer wants to email the URL to someone else. Our web page includes a mailto link that lets them do that.

PHP code

// The order system generates some opaque token
$token = 'w%a&!e#"^2(^@azW';

// Here is a URL to redeem that token
$redeemUrl = 'https://httpbin.org/get?token=' . urlencode($token);

// Actual contents we want for the email
$subject = 'I just bought this for you';
$body = 'Please enter your shipping details here: ' . $redeemUrl;

// A URI for the email as prescribed
$mailToUri = 'mailto:?subject=' . rawurlencode($subject) . '&body=' . rawurlencode($body);

// Print an HTML element with that mailto link
echo '<a href="' . htmlspecialchars($mailToUri) . '">Email your friend</a>';

Note: the above assumes you are outputting to a text/html document. If your output media type is text/json then simply use $retval['url'] = $mailToUri; because output encoding is handled by json_encode().

Test case

1. Run the code on a PHP test site (is there a canonical one I should mention here?)
2. Click the link
3. Send the email
4. Get the email
5. Click that link

You should see:

"args": {
  "token": "w%a&!e#\"^2(^@azW"
}, 

And of course this is the JSON representation of $token above.

I just got this same issue and I found that

$ svn revert foo bar

solved the problem.

svn resolve did not work for me:

$ svn st
!  +  C foo
      >   local edit, incoming delete upon update
!  +  C bar
      >   local edit, incoming delete upon update

$ svn resolve --accept working
svn: Try 'svn help' for more info
svn: Not enough arguments provided

$ svn resolve --accept working .

$ svn st
!  +  C foo
      >   local edit, incoming delete upon update
!  +  C bar
      >   local edit, incoming delete upon update

$ svn resolve --accept working foo
Resolved conflicted state of 'foo'

$ svn st
!  +    foo
!  +  C bar
      >   local edit, incoming delete upon update

The importance of the double quotes is worth emphasizing. Suppose an argument contains whitespace.

Code:

#!/bin/bash
printf 'arguments:%s\n' "$@"
declare -a arrayGOOD=( "$@" )
declare -a arrayBAAD=(  $@  )

printf '\n%s:\n' arrayGOOD
declare -p arrayGOOD
arrayGOODlength=${#arrayGOOD[@]}
for (( i=1; i<${arrayGOODlength}+1; i++ ));
do
   echo "${arrayGOOD[$i-1]}"
done

printf '\n%s:\n' arrayBAAD
declare -p arrayBAAD
arrayBAADlength=${#arrayBAAD[@]}
for (( i=1; i<${arrayBAADlength}+1; i++ ));
do
   echo "${arrayBAAD[$i-1]}"
done

Output:

> ./bash-array-practice.sh 'The dog ate the "flea" -- and ' the mouse.
arguments:The dog ate the "flea" -- and 
arguments:the
arguments:mouse.

arrayGOOD:
declare -a arrayGOOD='([0]="The dog ate the \"flea\" -- and " [1]="the" [2]="mouse.")'
The dog ate the "flea" -- and 
the
mouse.

arrayBAAD:
declare -a arrayBAAD='([0]="The" [1]="dog" [2]="ate" [3]="the" [4]="\"flea\"" [5]="--" [6]="and" [7]="the" [8]="mouse.")'
The

You can use it to raise errors as part of error-checking:

if (a < b):
    raise ValueError()

Or handle some errors, and then pass them on as part of error-handling:

try:
    f = open('file.txt', 'r')
except IOError:
    # do some processing here
    # and then pass the error on
    raise

I want to give a shoutout for using re module for this. Specially in the case of case sensitivity.

We use the option re.IGNORECASE while compiling the regex for use of in production environments with large amounts of data.

>>> import re
>>> m = ['isalnum','isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'ISALNUM', 'ISALPHA', 'ISDIGIT', 'ISLOWER', 'ISSPACE', 'ISTITLE', 'ISUPPER']
>>>
>>>
>>> pattern = re.compile('is')
>>>
>>> [word for word in m if pattern.match(word)]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

However try to always use the in operator for string comparison as detailed in this post

faster-operation-re-match-or-str

Also detailed in the one of the best books to start learning python with

idiomatic-python

>>> mylist = [["%s,%s"%(i,j) for j in range(columns)] for i in range(rows)]
>>> mylist
[['0,0', '0,1', '0,2'], ['1,0', '1,1', '1,2'], ['2,0', '2,1', '2,2']]
>>> zip(*mylist)
[('0,0', '1,0', '2,0'), ('0,1', '1,1', '2,1'), ('0,2', '1,2', '2,2')]
>>> sum(zip(*mylist),())
('0,0', '1,0', '2,0', '0,1', '1,1', '2,1', '0,2', '1,2', '2,2')

Here is another py2 approach, Im not sure if its the fastest or the most elegant nor safest ...

from collections import Iterable
from itertools import imap, repeat, chain


def flat(seqs, ignore=(int, long, float, basestring)):
    return repeat(seqs, 1) if any(imap(isinstance, repeat(seqs), ignore)) or not isinstance(seqs, Iterable) else chain.from_iterable(imap(flat, seqs))

It can ignore any specific (or derived) type you would like, it returns an iterator, so you can convert it to any specific container such as list, tuple, dict or simply consume it in order to reduce memory footprint, for better or worse it can handle initial non-iterable objects such as int ...

Note most of the heavy lifting is done in C, since as far as I know thats how itertools are implemented, so while it is recursive, AFAIK it isn't bounded by python recursion depth since the function calls are happening in C, though this doesn't mean you are bounded by memory, specially in OS X where its stack size has a hard limit as of today (OS X Mavericks) ...

there is a slightly faster approach, but less portable method, only use it if you can assume that the base elements of the input can be explicitly determined otherwise, you'll get an infinite recursion, and OS X with its limited stack size, will throw a segmentation fault fairly quickly ...

def flat(seqs, ignore={int, long, float, str, unicode}):
    return repeat(seqs, 1) if type(seqs) in ignore or not isinstance(seqs, Iterable) else chain.from_iterable(imap(flat, seqs))

here we are using sets to check for the type so it takes O(1) vs O(number of types) to check whether or not an element should be ignored, though of course any value with derived type of the stated ignored types will fail, this is why its using str, unicode so use it with caution ...

tests:

import random

def test_flat(test_size=2000):
    def increase_depth(value, depth=1):
        for func in xrange(depth):
            value = repeat(value, 1)
        return value

    def random_sub_chaining(nested_values):
        for values in nested_values:
            yield chain((values,), chain.from_iterable(imap(next, repeat(nested_values, random.randint(1, 10)))))

    expected_values = zip(xrange(test_size), imap(str, xrange(test_size)))
    nested_values = random_sub_chaining((increase_depth(value, depth) for depth, value in enumerate(expected_values)))
    assert not any(imap(cmp, chain.from_iterable(expected_values), flat(chain(((),), nested_values, ((),)))))

>>> test_flat()
>>> list(flat([[[1, 2, 3], [4, 5]], 6]))
[1, 2, 3, 4, 5, 6]
>>>

If your host is using suPHP, you can try creating a php.ini file in the same folder as the script and adding:

allow_url_fopen = On

(you can determine this by creating a file and checking which user it was created under: if you, it's suPHP, if "apache/nobody" or not you, then it's a normal PHP mode. You can also make a script

<?php
echo `id`;
?>

To give the same information, assuming shell_exec is not a disabled function)

As your example is linking to an external domain, if you are using HTTPS then you should verify that the external domain is setup for SSL as well. Otherwise, your users may see SSL errors and/or 404 errors (e.g. older versions of Plesk store HTTP and HTTPS in separate folders). For CDNs, it shouldn't be an issue but for any other website it could be.

On a side note, tested while updated an old website and also works in the url= part of a META REFRESH.

Ok found out the Tomcat file server.xml must be configured as well for the data source to work. So just add:

<Resource 
auth="Container" 
driverClassName="org.apache.derby.jdbc.EmbeddedDriver" 
maxActive="20" 
maxIdle="10" 
maxWait="-1" 
name="ds/flexeraDS" 
type="javax.sql.DataSource" 
url="jdbc:derby:flexeraDB;create=true" 
  />

You can use this code to check whether the input string contains any spaces?

public static void main(String[]args)
{
    Scanner sc=new Scanner(System.in);
    System.out.println("enter the string...");
    String s1=sc.nextLine();
    int l=s1.length();
    int count=0;
    for(int i=0;i<l;i++)
    {
        char c=s1.charAt(i);
        if(c==' ')
        {
        System.out.println("spaces are in the position of "+i);
        System.out.println(count++);
        }
        else
        {
        System.out.println("no spaces are there");
    }
}

for cakephp 2.0 Write this function in AppModel.php

function getLastQuery()
{
    $dbo = $this->getDatasource();
    $logs = $dbo->getLog();
    $lastLog = end($logs['log']);
    return $lastLog['query'];
}

To use this in Controller Write : echo $this->YourModelName->getLastQuery();

According to the latest pandas documentation you can read a csv file selecting only the columns which you want to read.

import pandas as pd

df = pd.read_csv('some_data.csv', usecols = ['col1','col2'], low_memory = True)

Here we use usecols which reads only selected columns in a dataframe.

We are using low_memory so that we Internally process the file in chunks.

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

Fluent API

public class SchoolContext : DbContext
{
    public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

You have to make sure the application is uninstalled.

In your phone, try going to settings/applications and show the list of all your installed applications, then make sure the application is uninstalled for all users (in my case I had uninstalled the application but still for others).

Look at the WAITFOR command.

E.g.

-- wait for 1 minute
WAITFOR DELAY '00:01'

-- wait for 1 second
WAITFOR DELAY '00:00:01'

This command allows you a high degree of precision but is only accurate within 10ms - 16ms on a typical machine as it relies on GetTickCount. So, for example, the call WAITFOR DELAY '00:00:00:001' is likely to result in no wait at all.

My two cents:

from itertools import repeat 

list(repeat(f(), x))  # for pure f
[f() for f in repeat(f, x)]  # for impure f

To quote:

Because map containers do not allow for duplicate key values, the insertion operation checks for each element inserted whether another element exists already in the container with the same key value, if so, the element is not inserted and its mapped value is not changed in any way.

So insert will not change the value if the key already exists, the [] operator will.

EDIT:

This reminds me of another recent question - why use at() instead of the [] operator to retrieve values from a vector. Apparently at() throws an exception if the index is out of bounds whereas [] operator doesn't. In these situations it's always best to look up the documentation of the functions as they will give you all the details. But in general, there aren't (or at least shouldn't be) two functions/operators that do the exact same thing.

My guess is that, internally, insert() will first check for the entry and afterwards itself use the [] operator.

• fill_parent will make the width or height of the element to be as large as the parent element, in other words, the container.

• wrap_content will make the width or height be as large as needed to contain the elements within it.

For those interested in text alignment, a simple solution is to create a new class:

.text-right-large {
    text-align: right;
}
@media (max-width: 991px) {
    .text-right-large {
        text-align: left;
    }
}

Then add that class:

<div class="row">
    <div class="col-lg-6 col-md-6">elements 1</div>
    <div class="col-lg-6 col-md-6 text-right-large">
        elements 2
    </div>
</div>

If you want to check if the dialog's open on a particular element you can do this:

if ($('#elem').closest('.ui-dialog').is(':visible')) { 
  // do something
}

Or if you just want to check if the element itself is visible you can do:

if ($('#elem').is(':visible')) { 
  // do something
}

Or...

if ($('#elem:visible').length) { 
  // do something
}

Here is the complete solution as a function:

function varDumpToString ($var)
{
    ob_start();
    var_dump($var);
    return ob_get_clean();
}

The easiest way would probably be to put your web resources into the assets folder then call:

webView.loadUrl("file:///android_asset/filename.html");

For Complete Communication between Java and Webview See This

Update: The assets folder is usually the following folder: <project>/src/main/assets This can be changed in the asset folder configuration setting in your <app>.iml file as:

<option name=”ASSETS_FOLDER_RELATIVE_PATH” value=”/src/main/assets” /> See Article Where to place the assets folder in Android Studio

To add to the above answers, there's a good article: Useful JVM Flags – Part 8 (GC Logging) by Patrick Peschlow.

A brief excerpt:

The flag -XX:+PrintGC (or the alias -verbose:gc) activates the “simple” GC logging mode

By default the GC log is written to stdout. With -Xloggc:<file> we may instead specify an output file. Note that this flag implicitly sets -XX:+PrintGC and -XX:+PrintGCTimeStamps as well.

If we use -XX:+PrintGCDetails instead of -XX:+PrintGC, we activate the “detailed” GC logging mode which differs depending on the GC algorithm used.

With -XX:+PrintGCTimeStamps a timestamp reflecting the real time passed in seconds since JVM start is added to every line.

If we specify -XX:+PrintGCDateStamps each line starts with the absolute date and time.

I have configus.yml with flows files

"pattern":
  - _(\d{14})_
"datetime_string":
  - "%m%d%Y%H%M%f"

in python code I use

data_time_real_file=re.findall(r""+flows[flow]["pattern"][0]+"", latest_file)

This method first checks the current orientation of UIImage and then it changes the orientation in a clockwise way and return UIImage.You can show this image as

self.imageView.image = rotateImage(currentUIImage)

   func rotateImage(image:UIImage)->UIImage
    {
        var rotatedImage = UIImage();
        switch image.imageOrientation
        {
            case UIImageOrientation.Right:
            rotatedImage = UIImage(CGImage:image.CGImage!, scale: 1, orientation:UIImageOrientation.Down);

           case UIImageOrientation.Down:
            rotatedImage = UIImage(CGImage:image.CGImage!, scale: 1, orientation:UIImageOrientation.Left);

            case UIImageOrientation.Left:
            rotatedImage = UIImage(CGImage:image.CGImage!, scale: 1, orientation:UIImageOrientation.Up);

             default:
            rotatedImage = UIImage(CGImage:image.CGImage!, scale: 1, orientation:UIImageOrientation.Right);
        }
        return rotatedImage;
    }

Swift 4 version

func rotateImage(image:UIImage) -> UIImage
    {
        var rotatedImage = UIImage()
        switch image.imageOrientation
        {
        case .right:
            rotatedImage = UIImage(cgImage: image.cgImage!, scale: 1.0, orientation: .down)

        case .down:
            rotatedImage = UIImage(cgImage: image.cgImage!, scale: 1.0, orientation: .left)

        case .left:
            rotatedImage = UIImage(cgImage: image.cgImage!, scale: 1.0, orientation: .up)

        default:
            rotatedImage = UIImage(cgImage: image.cgImage!, scale: 1.0, orientation: .right)
        }

        return rotatedImage
    }

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

dropdownlist.Items.Insert(0, new Listitem("--Select One--", "0");

POD_HOST=$(kubectl get pod $POD_NAME --template={{.status.podIP}})

This command will return you an IP

If an axes (generated by code below the code shown in the question) is sharing the range with the first axes, make sure that you set the range after the last plot of that axes.

Here's a recent css-tricks article which discusses this.

Some of the solutions in the above article (which are not mentioned here) are

1) -webkit-line-clamp and 2) Place an absolutely positioned element to the bottom right with fade out

Both methods assume the following markup:

<div class="module"> /* Add line-clamp/fade class here*/
  <p>Text here</p>
</div>

with css

.module {
  width: 250px;
  overflow: hidden;
}

1) -webkit-line-clamp

line-clamp FIDDLE (..for a maximum of 3 lines)

.line-clamp {
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;  
  max-height: 3.6em; /* I needed this to get it to work */
}

2) fade out

Let's say you set the line-height to 1.2em. If we want to expose three lines of text, we can just make the height of the container 3.6em (1.2em × 3). The hidden overflow will hide the rest.

Fade out FIDDLE

p
{
    margin:0;padding:0;
}
.module {
  width: 250px;
  overflow: hidden;
  border: 1px solid green;
  margin: 10px;
}

.fade {
  position: relative;
  height: 3.6em; /* exactly three lines */
}
.fade:after {
  content: "";
  text-align: right;
  position: absolute;
  bottom: 0;
  right: 0;
  width: 70%;
  height: 1.2em;
  background: linear-gradient(to right, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 50%);
}

Solution #3 - A combination using @supports

We can use @supports to apply webkit's line-clamp on webkit browsers and apply fade out in other browsers.

@supports line-clamp with fade fallback fiddle

<div class="module line-clamp">
  <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>
</div>

CSS

.module {
  width: 250px;
  overflow: hidden;
  border: 1px solid green;
  margin: 10px;
}

.line-clamp {
      position: relative;
      height: 3.6em; /* exactly three lines */
    }
.line-clamp:after {
      content: "";
      text-align: right;
      position: absolute;
      bottom: 0;
      right: 0;
      width: 70%;
      height: 1.2em;
      background: linear-gradient(to right, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 50%);
 }

@supports (-webkit-line-clamp: 3) {
    .line-clamp {
        display: -webkit-box;
        -webkit-line-clamp: 3;
        -webkit-box-orient: vertical;  
        max-height:3.6em; /* I needed this to get it to work */
        height: auto;
    }
    .line-clamp:after {
        display: none;
    }
}

If you think about the performace ,may be you can use "PERFORM" in a function just like this:

 PERFORM 1 FROM skytf.test_2 WHERE id=i LIMIT 1;
  IF FOUND THEN
      RAISE NOTICE ' found record id=%', i;  
  ELSE
      RAISE NOTICE ' not found record id=%', i;  
 END IF;

For me following worked:

in directive declare it like this:

.directive('myDirective', function() {
    return {
        restrict: 'E',
        replace: true,
        scope: {
            myFunction: '=',
        },
        templateUrl: 'myDirective.html'
    };
})  

In directive template use it in following way:

<select ng-change="myFunction(selectedAmount)">

And then when you use the directive, pass the function like this:

<data-my-directive
    data-my-function="setSelectedAmount">
</data-my-directive>

You pass the function by its declaration and it is called from directive and parameters are populated.

May be sometimes upgrading to a superuser might not be a good option. So apart from super user there are lot of other options which you can use. Open your terminal and type the following:

$ sudo su - postgres
[sudo] password for user: (type your password here)
$ psql
postgres@user:~$ psql
psql (10.5 (Ubuntu 10.5-1.pgdg18.04+1))
Type "help" for help.

postgres=# ALTER USER my_user WITH option

Also listing the list of options

SUPERUSER | NOSUPERUSER | CREATEDB | NOCREATEDB  | CREATEROLE | NOCREATEROLE |
CREATEUSER | NOCREATEUSER | INHERIT | NOINHERIT | LOGIN | NOLOGIN | REPLICATION|
NOREPLICATION | BYPASSRLS | NOBYPASSRLS | CONNECTION LIMIT connlimit | 
[ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password' | VALID UNTIL 'timestamp'

So in command line it will look like

postgres=# ALTER USER my_user WITH  LOGIN

OR use an encrypted password.

postgres=# ALTER USER my_user  WITH ENCRYPTED PASSWORD '5d41402abc4b2a76b9719d911017c592';

OR revoke permissions after a specific time.

postgres=# ALTER USER my_user  WITH VALID UNTIL '2019-12-29 19:09:00';

There isn't a direct way to do this like you've attempted.

The usual approach is to use "varargs" and check against the number of arguments. Something like:

function f(arg1, arg2, arg3)

  if nargin < 3
    arg3 =   'some default'
  end

end

There are a few fancier things you can do with isempty, etc., and you might want to look at Matlab central for some packages that bundle these sorts of things.

You might have a look at varargin, nargchk, etc. They're useful functions for this sort of thing. varargs allow you to leave a variable number of final arguments, but this doesn't get you around the problem of default values for some/all of them.

I had this problem, which seemed to be caused by something broken in the solution level packages folder. I deleted the contents of the folder and let nuget install all the packages again.

I could then install new packages again.

That chart is not showing percents. "#90" is not "90%". That chart shows the hexadecimal to decimal conversion. The hex number 90 (typically represented as 0x90) is equivalent to the decimal number 144.

Hexadecimal numbers are base-16, so each digit is a value between 0 and F. The maximum value for a two byte hex value (such as the transparency of a color) is 0xFF, or 255 in decimal. Thus 100% is 0xFF.

you need to take 2 (hex) chars at the same time... then calculate the int value and after that make the char conversion like...

char d = (char)intValue;

do this for every 2chars in the hex string

this works if the string chars are only 0-9A-F:

#include <stdio.h>
#include <string.h>

int hex_to_int(char c){
        int first = c / 16 - 3;
        int second = c % 16;
        int result = first*10 + second;
        if(result > 9) result--;
        return result;
}

int hex_to_ascii(char c, char d){
        int high = hex_to_int(c) * 16;
        int low = hex_to_int(d);
        return high+low;
}

int main(){
        const char* st = "48656C6C6F3B";
        int length = strlen(st);
        int i;
        char buf = 0;
        for(i = 0; i < length; i++){
                if(i % 2 != 0){
                        printf("%c", hex_to_ascii(buf, st[i]));
                }else{
                        buf = st[i];
                }
        }
}

A very simple way to do so with IPython that worked for me in Visual Studio Code is to add the following:

{
    "key": "ctrl+space",
    "command": "jupyter.runallcells"
  }

to the keybindings.json that you can access by typing F1 and 'open keyboard shortcuts'.

Android Doc says -

FLAG_ACTIVITY_NEW_TASK requirement is now enforced

With Android 9, you cannot start an activity from a non-activity context unless you pass the intent flag FLAG_ACTIVITY_NEW_TASK. If you attempt to start an activity without passing this flag, the activity does not start, and the system prints a message to the log.

Note: The flag requirement has always been the intended behavior, and was enforced on versions lower than Android 7.0 (API level 24). A bug in Android 7.0 prevented the flag requirement from being enforced.

That means for (Build.VERSION.SDK_INT <= Build.VERSION_CODES.M) || (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) it is mandatory to add Intent.FLAG_ACTIVITY_NEW_TASK while calling startActivity() from outside of an Activity context.

So it is better to add flag for all the versions -

...
Intent i = new Intent(this, Wakeup.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
...

Procedural elements like loops are not part of the SQL language and can only be used inside the body of a procedural language function, procedure (Postgres 11 or later) or a DO statement, where such additional elements are defined by the respective procedural language. The default is PL/pgSQL, but there are others.

Example with plpgsql:

DO
$do$
BEGIN 
   FOR i IN 1..25 LOOP
      INSERT INTO playtime.meta_random_sample
         (col_i, col_id)                       -- declare target columns!
      SELECT  i,     id
      FROM   tbl
      ORDER  BY random()
      LIMIT  15000;
   END LOOP;
END

For many tasks that can be solved with a loop, there is a shorter and faster set-based solution around the corner. Pure SQL equivalent for your example:

INSERT INTO playtime.meta_random_sample (col_i, col_id)
SELECT t.*
FROM   generate_series(1,25) i
CROSS  JOIN LATERAL (
   SELECT i, id
   FROM   tbl
   ORDER  BY random()
   LIMIT  15000
   ) t;

About generate_series():

• What is the expected behaviour for multiple set-returning functions in select clause?

About optimizing performance of random selections:

• Best way to select random rows PostgreSQL

Using new Ecma features are great but not all users have those available yet.

Following code will attach a new function named distinct to the Global Array object. If you are trying get distinct values of an array of objects, you can pass the name of the value to get the distinct values of that type.

Array.prototype.distinct = function(item){   var results = [];
for (var i = 0, l = this.length; i < l; i++)
    if (!item){
        if (results.indexOf(this[i]) === -1)
            results.push(this[i]);
        } else {
        if (results.indexOf(this[i][item]) === -1)
            results.push(this[i][item]);
    }
return results;};

Check out my post in CodePen for a demo.

With only css, you can define two css classes.

<style type="text/css">
    /* Over the pointer-events:none, set the cursor to not-allowed.
    On this way you will have a more user friendly cursor. */
    .disabledTab {
        cursor: not-allowed;
    }
    /* Clicks are not permitted and change the opacity. */
    li.disabledTab > a[data-toggle="tab"] {
        pointer-events: none;
        filter: alpha(opacity=65);
        -webkit-box-shadow: none;
        box-shadow: none;
        opacity: .65;
    }
</style>

This is an html template. The only thing needed is to set the class to your preferred list item.

<ul class="nav nav-tabs tab-header">
    <li>
        <a href="#tab-info" data-toggle="tab">Info</a>
    </li>
    <li class="disabledTab">
        <a href="#tab-date" data-toggle="tab">Date</a>
    </li>
    <li>
        <a href="#tab-photo" data-toggle="tab">Photo</a>
    </li>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="tab-info">Info</div>
    <div class="tab-pane active" id="tab-date">Date</div>
    <div class="tab-pane active" id="tab-photo">Photo</div>
</div>

Go to C drive root in cmd Type dir /x This will list down the directories name with ~.use that instead of Program Files in your jdk path

#include <stdio.h>
main()
{
    char str[100];
    int num;
    while(1) {
        printf("Enter a number: ");
        scanf("%[^0-9]%d",str,&num);
        printf("You entered the number %d\n",num);
    }
    return 0;
}

%[^0-9] in scanf() gobbles up all that is not between 0 and 9. Basically it cleans the input stream of non-digits and puts it in str. Well, the length of non-digit sequence is limited to 100. The following %d selects only integers in the input stream and places it in num.

You can wrap your query in another SELECT:

select count(*)
from
(
  select count(SID) tot  -- add alias
  from Test 
  where Date = '2012-12-10' 
  group by SID
) src;  -- add alias

See SQL Fiddle with Demo

In order for it to work, the count(SID) need a column alias and you have to provide an alias to the subquery itself.

In this part of your SP:

IF @DateFirst <> '' and @DateLast <> ''
   set @FinalSQL  = @FinalSQL
       + '  or convert (Date,DateLog) >=     ''' + @DateFirst
       + ' and convert (Date,DateLog) <=''' + @DateLast  

you are trying to concatenate strings and datetimes.

As the datetime type has higher priority than varchar/nvarchar, the + operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= ''' and others) to datetime or numeric values. And fails.

That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.

To amend the situation, you need to add explicit casting of your datetime variables to strings:

set @FinalSQL  = @FinalSQL
    + '  or convert (Date,DateLog) >=     ''' + convert(date, @DateFirst)
    + ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)

You'll also need to add closing single quotes:

set @FinalSQL  = @FinalSQL
    + '  or convert (Date,DateLog) >=     ''' + convert(date, @DateFirst) + ''''
    + ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''

   try{

     URL url = new URL(str);

     System.out.println("File : "+ url.getFile());
     System.out.println("Converting process Successfully");

   }  
   catch (MalformedURLException me){

      System.out.println("Converting process error");

 }

I hope this will help you.

The bind() method creates a new function instance whose this value is bound to the value that was passed into bind(). For example:

   window.color = "red"; 
   var o = { color: "blue" }; 
   function sayColor(){ 
       alert(this.color); 
   } 
   var objectSayColor = sayColor.bind(o); 
   objectSayColor(); //blue 

Here, a new function called objectSayColor() is created from sayColor() by calling bind() and passing in the object o. The objectSayColor() function has a this value equivalent to o, so calling the function, even as a global call, results in the string “blue” being displayed.

All modern browsers (tested with Chrome 4, Firefox 3.5, IE8, Opera 10 and Safari 4) will always request a favicon.ico unless you've specified a shortcut icon via <link>. So if you don't explicitly specify one, it's best to always have a favicon.ico file, to avoid a 404. Yahoo! suggests you make it small and cacheable.

And you don't have to go for a PNG just for the alpha transparency either. ICO files support alpha transparency just fine (i.e. 32-bit color), though hardly any tools allow you to create them. I regularly use Dynamic Drive's FavIcon Generator to create favicon.ico files with alpha transparency. It's the only online tool I know of that can do it.

There's also a free Photoshop plug-in that can create them.

Moving the file from which you are importing to an outside directory helps.
This is extra useful when your main file makes any other files in its own directory.
Ex:
Before:
Project
|---dir1
|-------main.py
|-------module1.py
After:
Project
|---module1.py
|---dir1
|-------main.py

Put the path of your chrome application and do not forget to put th %s at the end. I am still trying to open the browser with html code without saving the file... I will add the code when I'll find how.

The actual problem is not IE8, but the hacks that you use for earlier versions of IE.

IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.

I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...

Use var args

public long sum(int... numbers){
      if(numbers == null){ return 0L;}
      long result = 0L;
      for(int number: numbers){
         result += number;
      }
      return result;   
}

File FileOne.js:

module.exports = { ClientIDUnsplash : 'SuperSecretKey' };

File FileTwo.js:

var { ClientIDUnsplash } = require('./FileOne');

This example works best for React.

I recommend the following syntax for readability.

<? if ($condition): ?>
  <p>Content</p>
<? elseif ($other_condition): ?>
  <p>Other Content</p>
<? else: ?>
  <p>Default Content</p>
<? endif; ?>

Note, omitting php on the open tags does require that short_open_tags is enabled in your configuration, which is the default. The relevant curly-brace-free conditional syntax is always enabled and can be used regardless of this directive.

For PDOException: could not find driver for MySQL, and if it is Debian based OS,

sudo apt-get -y install php5-mysql

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

If you take a look at the official docs, you'll see right below append, extend. That's what your looking for.

There's also itertools.chain if you are more interested in efficient iteration than ending up with a fully populated data structure.

Would that be acceptable ? pure PHP

$country = geoip_country_code_by_name($_SERVER['REMOTE_ADDR']);
print $country;

Try to find out if DAO or the Repository pattern is most applicable to the following situation : Imagine you would like to provide a uniform data access API for a persistent mechanism to various types of data sources such as RDBMS, LDAP, OODB, XML repositories and flat files.

Also refer to the following links as well, if interested:

I put the following at the top of the faulting PHP file and the error was no longer display:

error_reporting(E_ERROR | E_PARSE);

Before abc was introduced you would see this frequently.

class Base(object):
    def go(self):
        raise NotImplementedError("Please Implement this method")


class Specialized(Base):
    def go(self):
        print "Consider me implemented"

Strangely, for the exact same issue, what helped me was changing the ' to 'v11.0' in the following section of the config.

<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>

Depending on your environment configuration, you may not have a public IP address on the EC2 instance that was created for your environment. You can check by:

1. Go to the EC2 Console
2. Find your instance and check the Description tab
3. If there is no Public IP...
4. Click Elastic IPs on the Navigation
5. Click Allocate new address
6. Choose Amazon for the pool
7. Click Allocate

Finally, select your new EIP and choose Associate address from the action menu. Associate that IP with your EC2 instance. You should be able to connect using eb ssh now.

You can reset the connection details by running eb ssh --setup.

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

As if often happens, your question suffers from a serious terminological error/ambiguity. In common speech it usually doesn't matter, but in the context of this specific problem it is critically important.

You see, there's no such thing as "hex value" and "decimal value" (or "hex number" and "decimal number"). "Hex" and "decimal" are properties of representations of values. Meanwhile, values (or numbers) by themselves have no representation, so they can't be "hex" or "decimal". For example, 0xF and 15 in C syntax are two different representations of the same number.

I would guess that your question, the way it is stated, suggests that you need to convert ASCII hex representation of a value (i.e. a string) into a ASCII decimal representation of a value (another string). One way to do that is to use an integer representation as an intermediate one: first, convert ASCII hex representation to an integer of sufficient size (using functions from strto... group, like strtol), then convert the integer into the ASCII decimal representation (using sprintf).

If that's not what you need to do, then you have to clarify your question, since it is impossible to figure it out from the way your question is formulated.

The best practice is to ajax load the order information when click tr tag, and render the information html in $('#orderDetails') like this:

  $.get('the_get_order_info_url', { order_id: the_id_var }, function(data){
    $('#orderDetails').html(data);
  }, 'script')

Alternatively, you can add class for each td that contains the order info, and use jQuery method $('.class').html(html_string) to insert specific order info into your #orderDetails BEFORE you show the modal, like:

  <% @restaurant.orders.each do |order| %>
  <!-- you should add more class and id attr to help control the DOM -->
  <tr id="order_<%= order.id %>" onclick="orderModal(<%= order.id  %>);">
    <td class="order_id"><%= order.id %></td>
    <td class="customer_id"><%= order.customer_id %></td>
    <td class="status"><%= order.status %></td>
  </tr>
  <% end %>

js:

function orderModal(order_id){
  var tr = $('#order_' + order_id);
  // get the current info in html table 
  var customer_id = tr.find('.customer_id');
  var status = tr.find('.status');

  // U should work on lines here:
  var info_to_insert = "order: " + order_id + ", customer: " + customer_id + " and status : " + status + ".";
  $('#orderDetails').html(info_to_insert);

  $('#orderModal').modal({
    keyboard: true,
    backdrop: "static"
  });
};

That's it. But I strongly recommend you to learn sth about ajax on Rails. It's pretty cool and efficient.

You can use .replaceWith()

$(function() {_x000D_
_x000D_
  $(".region").click(function(e) {_x000D_
    e.preventDefault();_x000D_
    var content = $(this).html();_x000D_
    $('#map').replaceWith('<div class="region">' + content + '</div>');_x000D_
  });_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="map">_x000D_
  <div class="region"><a href="link1">region1</a></div>_x000D_
  <div class="region"><a href="link2">region2</a></div>_x000D_
  <div class="region"><a href="link3">region3</a></div>_x000D_
</div>

Add .done() to your function

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
         url: 'api.php',                        
         data: 'id1='+q+'',                                                         
         dataType: 'json',
         async:false,                    
         success: function(data)          
         {   
            id = data[0];              
            vname = data[1];
         }
      }).done(function(){
           printWithAjax(); 
      });



 }//end of the for statement
}//end of ajax call function

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

echo $fspec | tr "/" "\n"|tail -1

#include <stdio.h>
#include <string.h>

int main(void){
    char word[17], outword[33];//17:16+1, 33:16*2+1
    int i, len;

    printf("Intro word:");
    fgets(word, sizeof(word), stdin);
    len = strlen(word);
    if(word[len-1]=='\n')
        word[--len] = '\0';

    for(i = 0; i<len; i++){
        sprintf(outword+i*2, "%02X", word[i]);
    }
    printf("%s\n", outword);
    return 0;
}

something like that?

'nearest
 n = 5
 'n = 10

 'value
 v = 496
 'v = 499 
 'v = 2348 
 'v = 7343

 'mod
 m = (v \ n) * n

 'diff between mod and the val
 i = v-m


 if i >= (n/2) then     
      msgbox m+n
 else
      msgbox m
 end if

Another possibility could be this:

var concat = String(5) + String(6);

If this happens, make sure that you don't have two entries for localhost in /etc/hosts with different IP addresses, like this (bad) example:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1       localhost localhost.localdomain localhost6 localhost6.localdomain6

To avoid confusion, make sure you only have one entry for localhost, preferably an IPv4 address, like this:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost  localhost.localdomain   localhost4.localdomain4 localhost4
::1       localhost6 localhost6.localdomain6

A word of caution here. In Objective-C, unlike many similar languages, you generally should try to avoid using exceptions for common error situations that may occur in normal operation.

Apple's documentation for Obj-C 2.0 states the following: "Important: Exceptions are resource-intensive in Objective-C. You should not use exceptions for general flow-control, or simply to signify errors (such as a file not being accessible)"

Apple's conceptual Exception handling documentation explains the same, but with more words: "Important: You should reserve the use of exceptions for programming or unexpected runtime errors such as out-of-bounds collection access, attempts to mutate immutable objects, sending an invalid message, and losing the connection to the window server. You usually take care of these sorts of errors with exceptions when an application is being created rather than at runtime. [.....] Instead of exceptions, error objects (NSError) and the Cocoa error-delivery mechanism are the recommended way to communicate expected errors in Cocoa applications."

The reasons for this is partly to adhere to programming idioms in Objective-C (using return values in simple cases and by-reference parameters (often the NSError class) in more complex cases), partly that throwing and catching exceptions is much more expensive and finally (and perpaps most importantly) that Objective-C exceptions are a thin wrapper around C's setjmp() and longjmp() functions, essentially messing up your careful memory handling, see this explanation.

This might be helpful for whoever else faces this problem. I finally figured out a solution. Turns out, even if we use the inline for "content-disposition" and specify a file name, the browsers still do not use the file name. Instead browsers try and interpret the file name based on the Path/URL.

You can read further on this URL: Securly download file inside browser with correct filename

This gave me an idea, I just created my URL route that would convert the URL and end it with the name of the file I wanted to give the file. So for e.g. my original controller call just consisted of passing the Order Id of the Order being printed. I was expecting the file name to be of the format Order{0}.pdf where {0} is the Order Id. Similarly for quotes, I wanted Quote{0}.pdf.

In my controller, I just went ahead and added an additional parameter to accept the file name. I passed the filename as a parameter in the URL.Action method.

I then created a new route that would map that URL to the format: http://localhost/ShoppingCart/PrintQuote/1054/Quote1054.pdf

routes.MapRoute("", "{controller}/{action}/{orderId}/{fileName}",
                new { controller = "ShoppingCart", action = "PrintQuote" }
                , new string[] { "x.x.x.Controllers" }
            );

This pretty much solved my issue. Hoping this helps someone!

You can also try: (I tried this and it worked for me)

SELECT ISNULL((SELECT SUM(columnA) FROM my_table WHERE columnB = 1),0)) INTO res;

The functionality is indeed similar (apart from the calling semantics, where call-template requires a name attribute and a corresponding names template).

However, the parser will not execute the same way.

From MSDN:

Unlike <xsl:apply-templates>, <xsl:call-template> does not change the current node or the current node-list.

Possibly:

select lpad(column, 8, 0) from table;

Edited in response to question from mylesg, in comments below:

ok, seems to make the change on the query- but how do I make it stick (change it) permanently in the table? I tried an UPDATE instead of SELECT

I'm assuming that you used a query similar to:

UPDATE table SET columnName=lpad(nums,8,0);

If that was successful, but the table's values are still without leading-zeroes, then I'd suggest you probably set the column as a numeric type? If that's the case then you'd need to alter the table so that the column is of a text/varchar() type in order to preserve the leading zeroes:

First:

ALTER TABLE `table` CHANGE `numberColumn` `numberColumn` CHAR(8);

Second, run the update:

UPDATE table SET `numberColumn`=LPAD(`numberColum`, 8, '0');

This should, then, preserve the leading-zeroes; the down-side is that the column is no longer strictly of a numeric type; so you may have to enforce more strict validation (depending on your use-case) to ensure that non-numerals aren't entered into that column.

References:

• lpad().

In C programming language, \ is used to print some of the special characters which has sepcial meaning in C. Those special characters are listed below

\\ - Backslash
\' - Single Quotation Mark
\" - Double Quatation Mark
\n - New line
\r - Carriage Return
\t - Horizontal Tab
\b - Backspace
\f - Formfeed
\a - Bell(beep) sound

Use this.getClass().getCanonicalName() to get the full class name.

Note that a package / class name ("a.b.C") is different from the path of the .class files (a/b/C.class), and that using the package name / class name to derive a path is typically bad practice. Sets of class files / packages can be in multiple different class paths, which can be directories or jar files.

First case: You want to import file A.py in file B.py, these two files are in the same folder, like this:

. 
+-- A.py 
+-- B.py

You can do this in file B.py:

import A

or

from A import *

or

from A import THINGS_YOU_WANT_TO_IMPORT_IN_A

Then you will be able to use all the functions of file A.py in file B.py

Second case: You want to import file folder/A.py in file B.py, these two files are not in the same folder, like this:

.
+-- B.py
+-- folder
     +-- A.py

You can do this in file B:

import folder.A

or

from folder.A import *

or

from folder.A import THINGS_YOU_WANT_TO_IMPORT_IN_A

Then you will be able to use all the functions of file A.py in file B.py

Summary: In the first case, file A.py is a module that you imports in file B.py, you used the syntax import module_name. In the second case, folder is the package that contains the module A.py, you used the syntax import package_name.module_name.

It is almost fine. Just have:

Player[] thePlayers = new Player[playerCount + 1];

And let the loop be:

for(int i = 0; i < thePlayers.length; i++)

And note that java convention dictates that names of methods and variables should start with lower-case.

Update: put your method within the class body.

Answered by zerkms is the correct method. But, if someone looking to insert more extra column in the table then you can get it from the following:

INSERT INTO action_2_members (`campaign_id`, `mobile`, `email`, `vote`, `vote_date`, `current_time`)
SELECT `campaign_id`, `from_number`, '[email protected]', `received_msg`, `date_received`, 1502309889 FROM `received_txts` WHERE `campaign_id` = '8'

In the above query, there are 2 extra columns named email & current_time.

You can try this

Process[] processes = Process.GetProcessesByName("processname");
foreach (Process p in processes)
{
    IntPtr pFoundWindow = p.MainWindowHandle;
    // Do something with the handle...
    //
}

Working Example:

https://github.com/python/cpython/archive/31af650.zip  

Description:

 `https://github.com/username/projectname/archive/commitshakey.zip`

If you have the long hash key 31af650ee25f65794b75d4dfefed6fe4758781c1, just get the first 7 chars 31af650. It's the default for GitHub.

What about this:

function($arg = NULL) {

    if ($arg != NULL) {
        etc.
        etc.
    }
}

Whoa there!

There's a potentially serious problem with this code, because it ignores the character encoding specified in the String (which is UTF-8 by default). When you call String.getBytes() the platform default encoding is used to encode Unicode characters to bytes. So, the parser may think it's getting UTF-8 data when in fact it's getting EBCDIC or something… not pretty!

Instead, use the parse method that takes an InputSource, which can be constructed with a Reader, like this:

import java.io.StringReader;
import org.xml.sax.InputSource;
…
        return builder.parse(new InputSource(new StringReader(xml)));

It may not seem like a big deal, but ignorance of character encoding issues leads to insidious code rot akin to y2k.

After struggling with this for hours trying to get it to work in IE8, 9, and 10 here's what worked for me.

This stripped-down CSS works in FF 26, Chrome 32, Opera 18, and IE9 -11 as of 1/7/2014:

.wrap
{
    width: 320px;
    height: 192px;
    padding: 0;
    overflow: hidden;
}

.frame
{
    width: 1280px;
    height: 786px;
    border: 0;

    -ms-transform: scale(0.25);
    -moz-transform: scale(0.25);
    -o-transform: scale(0.25);
    -webkit-transform: scale(0.25);
    transform: scale(0.25);

    -ms-transform-origin: 0 0;
    -moz-transform-origin: 0 0;
    -o-transform-origin: 0 0;
    -webkit-transform-origin: 0 0;
    transform-origin: 0 0;
}

For IE8, set the width/height to match the iframe, and add -ms-zoom to the .wrap container div:

.wrap
{
    width: 1280px; /* same size as frame */
    height: 768px;
    -ms-zoom: 0.25; /* for IE 8 ONLY */
}

Just use your favorite method for browser sniffing to conditionally include the appropriate CSS, see Is there a way to do browser specific conditional CSS inside a *.css file? for some ideas.

IE7 was a lost cause since -ms-zoom did not exist until IE8.

Here's the actual HTML I tested with:

<div class="wrap">
   <iframe class="frame" src="http://time.is"></iframe>
</div>
<div class="wrap">
    <iframe class="frame" src="http://apple.com"></iframe>
</div>

CREATE VIEW MyView AS
   SELECT Column, Value FROM Table;


SELECT Column FROM MyView WHERE Value = 1;

Is the proper solution in MySQL, some other SQLs let you define Views more exactly.

Note: Unless the View is very complicated, MySQL will optimize this just fine.

Bash:

 find -type f -printf "%T@ %p \n" \
     | sort  \
     | tail -n 1  \
     | sed -r "s/^\S+\s//;s/\s*$//" \
     | xargs -iSTR cp STR newestfile

where "newestfile" will become the newestfile

alternatively, you could do newdir/STR or just newdir

Breakdown:

1. list all files in {time} {file} format.
2. sort them by time
3. get the last one
4. cut off the time, and whitespace from the start/end
5. copy resulting value

Important

After running this once, the newest file will be whatever you just copied :p ( assuming they're both in the same search scope that is ). So you may have to adjust which filenumber you copy if you want this to work more than once.

In addition to other answers, there is sometimes the scenario where you wish to have private modules available in a team context.

Both Github and Bitbucket support the concept of generating a team API Key. This API key can be used as the password to perform API requests as this team.

In your private npm modules add

"private": true 

to your package.json

Then to reference the private module in another module, use this in your package.json

    {
        "name": "myapp",
        "dependencies": {
            "private-repo":
"git+https://myteamname:[email protected]/myprivate.git",
        }
    }

where team name = myteamname, and API Key = aQqtcplwFzlumj0mIDdRGCbsAq5d6Xg4

Here I reference a bitbucket repo, but it is almost identical using github too.

Finally, as an alternative, if you really don't mind paying $7 per month (as of writing) then you can now have private NPM modules out of the box.

Some nice guy handled the issue by using the Class 1 StartSSL certificate and shared Apache config that adds certificate support (will work with any certificate) and code for changing links in existing *.plist files automatically. Too long to copy, so here is the link: http://cases.azoft.com/how-to-fix-certificate-is-not-valid-error-on-ios-7/

FragmentActivity gives you all of the functionality of Activity plus the ability to use Fragments which are very useful in many cases, particularly when working with the ActionBar, which is the best way to use Tabs in Android.

If you are only targeting Honeycomb (v11) or greater devices, then you can use Activity and use the native Fragments introduced in v11 without issue. FragmentActivity was built specifically as part of the Support Library to back port some of those useful features (such as Fragments) back to older devices.

I should also note that you'll probably find the Backward Compatibility - Implementing Tabs training very helpful going forward.

This would require me to reformat the data into lists inside lists, which seems to defeat the purpose of using pandas in the first place.

No it doesn't, just convert to a NumPy array:

>>> data = np.asarray(df)

This takes constant time because it just creates a view on your data. Then feed it to scikit-learn:

>>> from sklearn.linear_model import LinearRegression
>>> lr = LinearRegression()
>>> X, y = data[:, 1:], data[:, 0]
>>> lr.fit(X, y)
LinearRegression(copy_X=True, fit_intercept=True, normalize=False)
>>> lr.coef_
array([  4.01182386e-01,   3.51587361e-04])
>>> lr.intercept_
14.952479503953672

If you are in that phase of development where you have an method inside your context class that creates testdata for you, don't call it in your constructor, it will try to create those test records while you don't have tables yet. Just sharing my mistake...

If you are facing this issue while using Kotlin and have

kotlin.incremental=true
kapt.incremental.apt=true

in the gradle.properties, then you need to remove this temporarily to fix the build.

After the successful build, you can again add these properties to speed up the build time while using Kotlin.

If like me, you are using some micro VM lacking of memory, creating a swap file does the trick:

#Check free memory before
free -m

mkdir -p /var/_swap_
cd /var/_swap_
#Here, 1M * 2000 ~= 2GB of swap memory.  Feel free to add MORE
dd if=/dev/zero of=swapfile bs=1M count=2000
chmod 600 swapfile
mkswap swapfile
swapon swapfile
#Automatically mount this swap partition at startup
echo "/var/_swap_/swapfile none swap sw 0 0" >> /etc/fstab

#Check free memory after
free -m

As several comments pointed out, don't forget to add sudo if you don't work as root.

btw, feel free to select another location/filename/size for the file.
/var is probably not the best place, but I don't know which place would be, and rarely care since tiny servers are mostly used for testing purposes.

UNNEST function with arrays can be used along with multirow VALUES syntax. I'm think that this method is slower than using COPY but it is useful to me in work with psycopg and python (python list passed to cursor.execute becomes pg ARRAY):

INSERT INTO tablename (fieldname1, fieldname2, fieldname3)
VALUES (
    UNNEST(ARRAY[1, 2, 3]), 
    UNNEST(ARRAY[100, 200, 300]), 
    UNNEST(ARRAY['a', 'b', 'c'])
);

without VALUES using subselect with additional existance check:

INSERT INTO tablename (fieldname1, fieldname2, fieldname3)
SELECT * FROM (
    SELECT UNNEST(ARRAY[1, 2, 3]), 
           UNNEST(ARRAY[100, 200, 300]), 
           UNNEST(ARRAY['a', 'b', 'c'])
) AS temptable
WHERE NOT EXISTS (
    SELECT 1 FROM tablename tt
    WHERE tt.fieldname1=temptable.fieldname1
);

the same syntax to bulk updates:

UPDATE tablename
SET fieldname1=temptable.data
FROM (
    SELECT UNNEST(ARRAY[1,2]) AS id,
           UNNEST(ARRAY['a', 'b']) AS data
) AS temptable
WHERE tablename.id=temptable.id;

For usages of Write-Host, PSScriptAnalyzer produces the following diagnostic:

Avoid using Write-Host because it might not work in all hosts, does not work when there is no host, and (prior to PS 5.0) cannot be suppressed, captured, or redirected. Instead, use Write-Output, Write-Verbose, or Write-Information.

See the documentation behind that rule for more information. Excerpts for posterity:

The use of Write-Host is greatly discouraged unless in the use of commands with the Show verb. The Show verb explicitly means "show on the screen, with no other possibilities".

Commands with the Show verb do not have this check applied.

Jeffrey Snover has a blog post Write-Host Considered Harmful in which he claims Write-Host is almost always the wrong thing to do because it interferes with automation and provides more explanation behind the diagnostic, however the above is a good summary.

if you are using macOS, use sudo command

sudo npm install -g npx

You can create temp stored procedures like:

create procedure #mytemp as
begin
   select getdate() into #mytemptable;
end

in an SQL script, but not functions. You could have the proc store it's result in a temp table though, then use that information later in the script ..

In addition to all the comments, I thought I might add some code on how to use java.util.Date, java.util.Calendar and java.util.GregorianCalendar according to the javadoc.

//Initialize your Date however you like it.
Date date = new Date();
Calendar calendar = new GregorianCalendar();
calendar.setTime(date);
int year = calendar.get(Calendar.YEAR);
//Add one to month {0 - 11}
int month = calendar.get(Calendar.MONTH) + 1;
int day = calendar.get(Calendar.DAY_OF_MONTH);

Let's say we have a string called yourstring:

for x in range(0, [howmanytimes you want it at the beginning]):
    yourstring = "L" + yourstring
for x in range(0, [howmanytimes you want it at the end]):
    yourstring += "L"

Much simpler to understand approach:

dict = { 'a':302, 'e':53, 'g':302, 'h':100 }
max_value_keys = [key for key in dict.keys() if dict[key] == max(dict.values())]
print(max_value_keys) # prints a list of keys with max value

Output: ['a', 'g']

Now you can choose only one key:

maximum = dict[max_value_keys[0]]

You can use sum() with a generator expression here. The generator expression will be [1, 1, ...] up to the length of the file. Then we call sum() to add them all together, to get the total count.

with open('text.txt') as myfile:
    count = sum(1 for line in myfile)

It seems by what you have tried that you don't want to include empty lines. You can then do:

with open('text.txt') as myfile:
    count = sum(1 for line in myfile if line.rstrip('\n'))

The answer by @GordonM is good. But it would fail if the $string is already true (ie, the string isn't a string but boolean TRUE)...which seems illogical.

Extending his answer, I'd use:

$test_mode_mail = ($string === 'true' OR $string === true));

came out of this issue by changing the version in package.json file and also changing the name of the package and finally deleted the package-lock.json file

What exactly are the rules for requesting retransmission of lost data?

The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.

Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ

are detailed in the RFC 3366.

At what time frequency are the retransmission requests performed?

The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)

The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.

Is there an upper bound on the number?

Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.

Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?

The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

re.sub is definitely what you are looking for. And so you know, you don't need the anchors and the wildcards.

re.sub(r"(?i)interfaceOpDataFile", "interfaceOpDataFile %s" % filein, line)

will do the same thing--matching the first substring that looks like "interfaceOpDataFile" and replacing it.

I find the following setup the easiest.

Use the default config file loading mechanism of DispatcherServlet:

The framework will, on initialization of a DispatcherServlet, look for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and create the beans defined there (overriding the definitions of any beans defined with the same name in the global scope).

In your case, simply create a file intrafest-servlet.xml in the WEB-INF dir and don't need to specify anything specific information in web.xml.

In intrafest-servlet.xml file you can use import to compose your XML configuration.

<beans>
  <bean id="bean1" class="..."/>
  <bean id="bean2" class="..."/>

  <import resource="foo-services.xml"/>
  <import resource="foo-persistence.xml"/>
</beans>

Note that the Spring team actually prefers to load multiple config files when creating the (Web)ApplicationContext. If you still want to do it this way, I think you don't need to specify both context parameters (context-param) and servlet initialization parameters (init-param). One of the two will do. You can also use commas to specify multiple config locations.

If you check out the subprocess section of the Python docs, you'll notice there is an example of how to replace os.system() with subprocess.Popen():

sts = os.system("mycmd" + " myarg")

...does the same thing as...

sts = Popen("mycmd" + " myarg", shell=True).wait()

The "improved" code looks more complicated, but it's better because once you know subprocess.Popen(), you don't need anything else. subprocess.Popen() replaces several other tools (os.system() is just one of those) that were scattered throughout three other Python modules.

If it helps, think of subprocess.Popen() as a very flexible os.system().

Sed one-liner, that takes sections into account. Example file:

[section1]
param1=123
param2=345
param3=678

[section2]
param1=abc
param2=def
param3=ghi

[section3]
param1=000
param2=111
param3=222

Say you want param2 from section2. Run the following:

sed -nr "/^\[section2\]/ { :l /^param2[ ]*=/ { s/.*=[ ]*//; p; q;}; n; b l;}" ./file.ini

will give you

def

I used jordan314's solution, but then I added "border-light" class to select. If you have default border-light class defined in css, you can directly use it. It just defines the border as white). I changed the border to square/remove the radius, and maintained the arrow.

Here is what I did:

<select class="form-control border border-light" id="type">
   <option>Select</option>
   <option value="mobile">Apple</option>
 </select>

if you don't have the predefined border-light, just add in your css:

<style>
.border-light{
         border-color:#f8f9fa!important
     }

 #type {
   border:0;
   outline:1px solid #ddd;
   background-color:white;
 }
</style>

I tested the previous answers found here: Assuming that we want the other four sheets to remain, the previous answers here did not work, because the other four sheets were deleted. In case we want them to remain use xlwings:

import xlwings as xw
import pandas as pd

filename = "test.xlsx"

df = pd.DataFrame([
    ("a", 1, 8, 3),
    ("b", 1, 2, 5),
    ("c", 3, 4, 6),
    ], columns=['one', 'two', 'three', "four"])

app = xw.App(visible=False)
wb = xw.Book(filename)
ws = wb.sheets["Sheet5"]

ws.clear()
ws["A1"].options(pd.DataFrame, header=1, index=False, expand='table').value = df

# If formatting of column names and index is needed as xlsxwriter does it, 
# the following lines will do it (if the dataframe is not multiindex).
ws["A1"].expand("right").api.Font.Bold = True
ws["A1"].expand("down").api.Font.Bold = True
ws["A1"].expand("right").api.Borders.Weight = 2
ws["A1"].expand("down").api.Borders.Weight = 2

wb.save(filename)
app.quit()

Running the address_parser.py

 python3 address_parser.py 9757 East Arcadia Ave. Saugus MA 01906
 {"addressStreet": "9757 East Arcadia Ave.", "addressCity": "Saugus", "addressState": "MA", "addressPostalCode": "01906"}

I had a similar problem. I had HTML files and videos in the assets-folder of my app.

Therefore the videos were located inside of the APK. Because the APK is really a ZIP-file, the WebView was not able to read the video-files.

Copying all HTML- and video-files onto the SD-Card worked for me.

Use urlencode() rather than trying to implement your own. Be lazy.

On centos 7 I have used:

yum install php-pecl-zip

because any other solution didn't work for me.

From the STRTOTIME writeup Note:

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

It is as simple as that.

you can also add animation in your activity, in onCreate method like below becasue overridePendingTransition is not working with some mobile, or it depends on device settings...

View view = findViewById(android.R.id.content);
Animation mLoadAnimation = AnimationUtils.loadAnimation(getApplicationContext(), android.R.anim.fade_in);
mLoadAnimation.setDuration(2000);
view.startAnimation(mLoadAnimation);

You could also set them to float to the right.

#ul_top_hypers li {
    float: right;
}

This allows them to still be block level, but will appear on the same line.

If you want to convert from char to int, why not think about unicode number?

SELECT UNICODE(';') -- 59

This way you can convert any char to int without any error. Cheers.

In IE to move cursor on some position this code is enough:

var range = elt.createTextRange();
range.move('character', pos);
range.select();

replace code in onClick() method with this:

Intent myIntent = new Intent(this, Katra_home.class);
startActivity(myIntent);

Use java.sql.Timestamp.toString if you want to get fractional seconds in text representation. The difference betwen Timestamp from DB and Java Date is that DB precision is nanoseconds while Java Date precision is milliseconds.

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

import pandas as pd
pd.options.display.float_format = '${:,.2f}'.format
df = pd.DataFrame([123.4567, 234.5678, 345.6789, 456.7890],
                  index=['foo','bar','baz','quux'],
                  columns=['cost'])
print(df)

yields

        cost
foo  $123.46
bar  $234.57
baz  $345.68
quux $456.79

but this only works if you want every float to be formatted with a dollar sign.

Otherwise, if you want dollar formatting for some floats only, then I think you'll have to pre-modify the dataframe (converting those floats to strings):

import pandas as pd
df = pd.DataFrame([123.4567, 234.5678, 345.6789, 456.7890],
                  index=['foo','bar','baz','quux'],
                  columns=['cost'])
df['foo'] = df['cost']
df['cost'] = df['cost'].map('${:,.2f}'.format)
print(df)

yields

         cost       foo
foo   $123.46  123.4567
bar   $234.57  234.5678
baz   $345.68  345.6789
quux  $456.79  456.7890

A bin is range that represents the width of a single bar of the histogram along the X-axis. You could also call this the interval. (Wikipedia defines them more formally as "disjoint categories".)

The Numpy histogram function doesn't draw the histogram, but it computes the occurrences of input data that fall within each bin, which in turns determines the area (not necessarily the height if the bins aren't of equal width) of each bar.

In this example:

 np.histogram([1, 2, 1], bins=[0, 1, 2, 3])

There are 3 bins, for values ranging from 0 to 1 (excl 1.), 1 to 2 (excl. 2) and 2 to 3 (incl. 3), respectively. The way Numpy defines these bins if by giving a list of delimiters ([0, 1, 2, 3]) in this example, although it also returns the bins in the results, since it can choose them automatically from the input, if none are specified. If bins=5, for example, it will use 5 bins of equal width spread between the minimum input value and the maximum input value.

The input values are 1, 2 and 1. Therefore, bin "1 to 2" contains two occurrences (the two 1 values), and bin "2 to 3" contains one occurrence (the 2). These results are in the first item in the returned tuple: array([0, 2, 1]).

Since the bins here are of equal width, you can use the number of occurrences for the height of each bar. When drawn, you would have:

• a bar of height 0 for range/bin [0,1] on the X-axis,
• a bar of height 2 for range/bin [1,2],
• a bar of height 1 for range/bin [2,3].

You can plot this directly with Matplotlib (its hist function also returns the bins and the values):

>>> import matplotlib.pyplot as plt
>>> plt.hist([1, 2, 1], bins=[0, 1, 2, 3])
(array([0, 2, 1]), array([0, 1, 2, 3]), <a list of 3 Patch objects>)
>>> plt.show()

I addition to the accepted answer, the error can also occur when the destination folder is read-only (Common when using TFS)
