I encountered the same problem and found a very easy solution.Go to the following Link: http://msdn.microsoft.com/en-us/vs2008/bb968856.aspx

and run VS AutoUninstall tool .This will automatically remove all the components of VS 2008.

Cheers

Your file should be available as com/example/foo/myProps.properties in classpath. Then load it as:

props.load(this.getClass().getResourceAsStream("myProps.properties"));

I use the DataGridView's Invalidate() function. However, that will refresh the entire DataGridView. If you want to refresh a particular row, you use dgv.InvalidateRow(rowIndex). If you want to refresh a particular cell, you can use dgv.InvalidateCell(columnIndex, rowIndex). This is of course assuming you're using a binding source or data source.

This worked for me:

np_arr = torch_tensor.cpu().detach().numpy()

you just provide one <folder> argument to npm install, argument should point toward the local folder instead of the package name:

npm install /path

What is parsing?

In computer science, parsing is the process of analysing text to determine if it belongs to a specific language or not (i.e. is syntactically valid for that language's grammar). It is an informal name for the syntactic analysis process.

For example, suppose the language a^n b^n (which means same number of characters A followed by the same number of characters B). A parser for that language would accept AABB input and reject the AAAB input. That is what a parser does.

In addition, during this process a data structure could be created for further processing. In my previous example, it could, for instance, to store the AA and BB in two separate stacks.

Anything that happens after it, like giving meaning to AA or BB, or transform it in something else, is not parsing. Giving meaning to parts of an input sequence of tokens is called semantic analysis.

What isn't parsing?

• Parsing is not transform one thing into another. Transforming A into B, is, in essence, what a compiler does. Compiling takes several steps, parsing is only one of them.
• Parsing is not extracting meaning from a text. That is semantic analysis, a step of the compiling process.

What is the simplest way to understand it?

I think the best way for understanding the parsing concept is to begin with the simpler concepts. The simplest one in language processing subject is the finite automaton. It is a formalism to parsing regular languages, such as regular expressions.

It is very simple, you have an input, a set of states and a set of transitions. Consider the following language built over the alphabet { A, B }, L = { w | w starts with 'AA' or 'BB' as substring }. The automaton below represents a possible parser for that language whose all valid words starts with 'AA' or 'BB'.

    A-->(q1)--A-->(qf)
   /  
 (q0)    
   \          
    B-->(q2)--B-->(qf)

It is a very simple parser for that language. You start at (q0), the initial state, then you read a symbol from the input, if it is A then you move to (q1) state, otherwise (it is a B, remember the remember the alphabet is only A and B) you move to (q2) state and so on. If you reach (qf) state, then the input was accepted.

As it is visual, you only need a pencil and a piece of paper to explain what a parser is to anyone, including a child. I think the simplicity is what makes the automata the most suitable way to teaching language processing concepts, such as parsing.

Finally, being a Computer Science student, you will study such concepts in-deep at theoretical computer science classes such as Formal Languages and Theory of Computation.

Similar to other posts, but with an important distinction to make this work inside a div. The simpler answers aren't very copy-paste-able because they directly modify div or draw over the entire page.

The key here is that the containing div dividedbox has relative positioning, allowing it to sit nicely in your document with the other elements, while the quarters within have absolute positioning, giving you vertical/horizontal control inside the containing div.

As a bonus, text is responsively centered in the quarters.

HTML:

<head>
  <meta charset="utf-8">
  <title>Box model</title>
  <link rel="stylesheet" href="style.css">
</head>

<body>
  <h1 id="title">Title Bar</h1>
  <div id="dividedbox">
    <div class="quarter" id="NW">
      <p>NW</p>
    </div>
    <div class="quarter" id="NE">
      <p>NE</p>
    </div>
    <div class="quarter" id="SE">
      <p>SE</p>
    </div>?
    <div class="quarter" id="SW">
      <p>SW</p>
    </div>
  </div>
</body>

</html>

CSS:

html, body { height:95%;} /* Important to make sure your divs have room to grow in the document */
#title { background: lightgreen}
#dividedbox { position: relative; width:100%; height:95%}   /* for div growth */
.quarter {position: absolute; width:50%; height:50%;  /* gives quarters their size */
  display: flex; justify-content: center; align-items: center;} /* centers text */
#NW { top:0;    left:0;     background:orange;     }
#NE { top:0;    left:50%;   background:lightblue;  }
#SW { top:50%;  left:0;     background:green;      }
#SE { top:50%;  left:50%;   background:red;        }

The bookmarks extension mentioned in the accepted answer conflicts with toggling breakpoints via the margin.

You could do the same with breakpoints and select the debug tab on the left to see them listed. Better yet, use File, Preferences, Keyboard Shortcuts and set (Shift+)Ctrl+F9 to navigate between them, even across files:

There must be more to a Python dictionary than a table lookup on hash(). By brute experimentation I found this hash collision:

>>> hash(1.1)
2040142438
>>> hash(4504.1)
2040142438

Yet it doesn't break the dictionary:

>>> d = { 1.1: 'a', 4504.1: 'b' }
>>> d[1.1]
'a'
>>> d[4504.1]
'b'

Sanity check:

>>> for k,v in d.items(): print(hash(k))
2040142438
2040142438

Possibly there's another lookup level beyond hash() that avoids collisions between dictionary keys. Or maybe dict() uses a different hash.

(By the way, this in Python 2.7.10. Same story in Python 3.4.3 and 3.5.0 with a collision at hash(1.1) == hash(214748749.8).)

Can't you import it as a git project and then (if you have the m2eclipse installed) right click on the project in the Package Explorer > Maven > Enable Dependency Management?

User Control with jQuery Inside an UpdatePanel

This isn't a direct answer to the question, but I did put this solution together by reading the answers that I found here, and I thought someone might find it useful.

I was trying to use a jQuery textarea limiter inside of a User Control. This was tricky, because the User Control runs inside of an UpdatePanel, and it was losing its bindings on callback.

If this was just a page, the answers here would have applied directly. However, User Controls do not have direct access to the head tag, nor did they have direct access to the UpdatePanel as some of the answers assume.

I ended up putting this script block right into the top of my User Control's markup. For the initial bind, it uses $(document).ready, and then it uses prm.add_endRequest from there:

<script type="text/javascript">
    function BindControlEvents() {
        //jQuery is wrapped in BindEvents function so it can be re-bound after each callback.
        //Your code would replace the following line:
            $('#<%= TextProtocolDrugInstructions.ClientID %>').limit('100', '#charsLeft_Instructions');            
    }

    //Initial bind
    $(document).ready(function () {
        BindControlEvents();
    });

    //Re-bind for callbacks
    var prm = Sys.WebForms.PageRequestManager.getInstance(); 

    prm.add_endRequest(function() { 
        BindControlEvents();
    }); 

</script>

So... Just thought someone might like to know that this works.

You can enable this in Window - Preferences - General - Workspace - Refresh Automatically (called Refresh using native hooks or polling in newer builds)

The only reason I can think why this isn't enabled by default is performance related.

For example, refreshing source folders automatically might trigger a build of the workspace. Perhaps some people want more control over this.

There is also an article on the Eclipse site regarding auto refresh.

Basically, there is no external trigger that notifies Eclipse of files changed outside the workspace. Rather a background thread is used by Eclipse to monitor file changes that can possibly lead to performance issues with large workspaces.

You cannot use double binding with hidden field. The solution is to use brackets :

<input type="hidden" name="someData" value="{{data}}" /> {{data}}

EDIT : See this thread on github : https://github.com/angular/angular.js/pull/2574

EDIT:

Since Angular 1.2, you can use 'ng-value' directive to bind an expression to the value attribute of input. This directive should be used with input radio or checkbox but works well with hidden input.

Here is the solution using ng-value:

<input type="hidden" name="someData" ng-value="data" />

Here is a fiddle using ng-value with an hidden input: http://jsfiddle.net/6SD9N

also could not get beyond:

default: SSH auth method: private key

When I used the VirtualBox GUI, it told me there was an OS processor mismatch.

To get vagrant up progressing further, in the BIOS settings I had to counter-intuitively:

Disable: Virtualisation

Enable: VT-X

Try toggling these setting in your BIOS.

$('input, select').attr('disabled', 'disabled');

Solution 1: Remove the explicit type definition

Since getPerson already returns a Person with a name, we can use the inferred type.

function getPerson(){
  let person = {name:"John"};
  return person;
}

let person = getPerson();

If we were to define person: Person we would lose a piece of information. We know getPerson returns an object with a non-optional property called name, but describing it as Person would bring the optionality back.

Solution 2: Use a more precise definition

type Require<T, K extends keyof T> = T & {
  [P in K]-?: T[P]
};

function getPerson() {
  let person = {name:"John"};
  return person;
}

let person: Require<Person, 'name'> = getPerson();
let name1:string = person.name;

Solution 3: Redesign your interface

A shape in which all properties are optional is called a weak type and usually is an indicator of bad design. If we were to make name a required property, your problem goes away.

interface Person {
  name:string,
  age?:string,
  gender?:string,
  occupation?:string,
}

if you are using jQuery; this is one a way to do it:

$('.link').each(function() {
    $(this).css('text-transform','capitalize').text($(this).text().toLowerCase());
});

Here is an easier to read version doing the same thing:

//Iterate all the elements in jQuery object
$('.link').each(function() {

    //get text from element and make it lower-case
    var string = $(this).text().toLowerCase();

    //set element text to the new string that is lower-case
    $(this).text(string);

    //set the css to capitalize
    $(this).css('text-transform','capitalize');
});

Demo

You need to add a Serializable attribute to the class which you want to serialize.

[Serializable]
public class OrgPermission

By stacking each switch case, you achieve the OR condition.

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7:
    case 12:
    ...
    break;
    ...

                else if (dtNew.AsEnumerable().Any(r => Enumerable.SequenceEqual(r.ItemArray, row.ItemArray))
                    && !dtOld.AsEnumerable().Any(r => Enumerable.SequenceEqual(r.ItemArray, row.ItemArray)))
                {
                    dtAdded.Rows.Add(row.ItemArray);
                }
            }
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.ToString());
        }
    }

in my experince the problem using result() and result_array() in my JSON if using result() there no problem its works but if using result_array() i got error "Trying to get property of non-object" so im not search into deep the problem so i just using result() if using JSON and using result_array() if not using JSON

There is still no solution that preserves newlines.

This is not true - you're probably just being misled by the behaviour of echo:

echo $VAR # strips newlines

echo "$VAR" # preserves newlines

If you are using OS X, you might have to create your .bash_profile file before running the installation command. That did it for me.

Create the profile file

touch ~/.bash_profile

Re-run the install and you'll see a relevant line in the output this time.

=> Appending source string to /Users/{username}/.bash_profile

Reload your profile (or close/re-open the Terminal window).

.  ~/.bash_profile

The Z stands for 'Zulu' - your times are in UTC. From Wikipedia:

The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet and amateur radio word for Z is "Zulu", UTC is sometimes known as Zulu time. This is especially true in aviation, where Zulu is the universal standard.

One way to avoid errors during installing or updating packages is to run the Anaconda prompt as Administrator. Hope it helps!

So the problem must be with your JCE Unlimited Strength installation.

Be sure you overwrite the local_policy.jar and US_export_policy.jar in both your JDK's jdk1.6.0_25\jre\lib\security\ and in your JRE's lib\security\ folder.

In my case I would place the new .jars in:

C:\Program Files\Java\jdk1.6.0_25\jre\lib\security

and

C:\Program Files\Java\jre6\lib\security

If you are running Java 8 and you encounter this issue. Below steps should help!

Go to your JRE installation (e.g - jre1.8.0_181\lib\security\policy\unlimited) copy local_policy.jar and replace it with 'local_policy.jar' in your JDK installation directory (e.g - jdk1.8.0_141\jre\lib\security).

Yes, it's a valid test although there's an implicit conversion from int to double. For clarity/simplicity you should use (foo.x == 0.0) to test. That will hinder NAN errors/division by zero, but the double value can in some cases be very very very close to 0, but not exactly zero, and then the test will fail (I'm talking about in general now, not your code). Division by that will give huge numbers.

If this has anything to do with money, do not use float or double, instead use BigDecimal.

I know this is an old question, but I thought I'd add my two cents anyway:

It depends on what the link is going to do, but usually, I would be pointing the link at a url that could possibly be displaying/doing the same thing, for example, if you're making a little about box pop up:

<a id="about" href="/about">About</a>

Then with jQuery

$('#about').click(function(e) {
    $('#aboutbox').show();
    e.preventDefault();
});

This way, very old browsers (or browsers with JavaScript disabled) can still navigate to a separate about page, but more importantly, Google will also pick this up and crawl the contents of the about page.

What I have found best is a CSRF token and save it in the session for links where you need to verify the referrer.

So if you are generating a FB callback then it would look something like this:

$token = uniqid(mt_rand(), TRUE);
$_SESSION['token'] = $token;
$url = "http://example.com/index.php?token={$token}";

Then the index.php will look like this:

if(empty($_GET['token']) || $_GET['token'] !== $_SESSION['token'])
{
    show_404();
} 

//Continue with the rest of code

I do know of secure sites that do the equivalent of this for all their secure pages.

File sutest

#!/bin/bash
echo "uid is ${UID}"
echo "user is ${USER}"
echo "username is ${USERNAME}"

run it: `./sutest' gives me

uid is 500
user is stephenp
username is stephenp

but using sudo: sudo ./sutest gives

uid is 0
user is root
username is stephenp

So you retain the original user name in $USERNAME when running as sudo. This leads to a solution similar to what others posted:

#!/bin/bash
sudo -u ${USERNAME} normal_command_1
root_command_1
root_command_2
sudo -u ${USERNAME} normal_command_2
# etc.

Just sudo to invoke your script in the first place, it will prompt for the password once.

I originally wrote this answer on Linux, which does have some differences with OS X

OS X (I'm testing this on Mountain Lion 10.8.3) has an environment variable SUDO_USER when you're running sudo, which can be used in place of USERNAME above, or to be more cross-platform the script could check to see if SUDO_USER is set and use it if so, or use USERNAME if that's set.

Changing the original script for OS X, it becomes...

#!/bin/bash
sudo -u ${SUDO_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${SUDO_USER} normal_command_2
# etc.

A first stab at making it cross-platform could be...

#!/bin/bash
#
# set "THE_USER" to SUDO_USER if that's set,
#  else set it to USERNAME if THAT is set,
#   else set it to the string "unknown"
# should probably then test to see if it's "unknown"
#
THE_USER=${SUDO_USER:-${USERNAME:-unknown}}

sudo -u ${THE_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${THE_USER} normal_command_2
# etc.

Each cell in the array is treated as unsigned int:

private int unsignedIntFromByteArray(byte[] bytes) {
int res = 0;
if (bytes == null)
    return res;


for (int i=0;i<bytes.length;i++){
    res = res | ((bytes[i] & 0xff) << i*8);
}
return res;
}

Let me introduce you to my friend "dotglob". It turns on and off whether or not "*" includes hidden files.

$ mkdir test
$ cd test
$ touch a b c .hidden .hi .den
$ ls -a
. ..  .den  .hi .hidden a b c

$ shopt -u dotglob
$ ls *
a b c
$ for i in * ; do echo I found: $i ; done
I found: a
I found: b
I found: c

$ shopt -s dotglob
$ ls *
.den  .hi .hidden a b c
$ for i in * ; do echo I found: $i ; done
I found: .den
I found: .hi
I found: .hidden
I found: a
I found: b
I found: c

It defaults to "off".

$ shopt dotglob
dotglob         off

It is best to turn it back on when you are done otherwise you will confuse things that assume it will be off.

The object name is not very important. what you should be focusing at is the variable that stores the lineedit object (le) and your pushbutton object(pb)

QObject(self.pb, SIGNAL("clicked()"), self.button_clicked)

def button_clicked(self):
  self.le.setText("shost")

I think this is what you want. I hope i got your question correctly :)

If destroy() and clear() is not working (just like what i had experience) you can use jquery to remove the canvas and append it again.

    $('#chartAmazon').remove();
    $('#chartBar').append('<canvas id="chartAmazon"></canvas>');

    var ctxAmazon = $("#chartAmazon").get(0).getContext("2d");
      var AmazonChart = new Chart(ctxAmazon, {
        type: 'doughnut',
        data: dataAmazon,
        options: optionsA
    });

You can also do like this if you're only interested in extracting the "user_id":

String userId = 
given().
        contentType("application/json").
        body(requestBody).
when().
        post("/admin").
then().
        statusCode(200).
extract().
        path("user_id");

In its simplest form it looks like this:

String userId = get("/person").path("person.userId");

In case this help out anyone else, in my case, I was using a CMK (it worked fine using the default aws/s3 key)

I had to go into my encryption key definition in IAM and add the programmatic user logged into boto3 to the list of users that "can use this key to encrypt and decrypt data from within applications and when using AWS services integrated with KMS.".

As suggested by @EboMike I saved the bitmap in a file named myImage in the internal storage of my application not accessible my other apps. Here's the code of that part:

public String createImageFromBitmap(Bitmap bitmap) {
    String fileName = "myImage";//no .png or .jpg needed
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
        fo.write(bytes.toByteArray());
        // remember close file output
        fo.close();
    } catch (Exception e) {
        e.printStackTrace();
        fileName = null;
    }
    return fileName;
}

Then in the next activity you can decode this file myImage to a bitmap using following code:

Bitmap bitmap = BitmapFactory.decodeStream(context
                    .openFileInput("myImage"));//here context can be anything like getActivity() for fragment, this or MainActivity.this

Note A lot of checking for null and scaling bitmap's is ommited.

Answers that suggest that the header provided in the question are supported out of the box by WCF are incorrect. The header in the question contains a Nonce and a Created timestamp in the UsernameToken, which is an official part of the WS-Security specification that WCF does not support. WCF only supports username and password out of the box.

If all you need to do is add a username and password, then Sergey's answer is the least-effort approach. If you need to add any other fields, you will need to supply custom classes to support them.

A somewhat more elegant approach that I found was to override the ClientCredentials, ClientCredentialsSecurityTokenManager and WSSecurityTokenizer classes to support the additional properties. I've provided a link to the blog post where the approach is discussed in detail, but here is the sample code for the overrides:

public class CustomCredentials : ClientCredentials
{
    public CustomCredentials()
    { }

    protected CustomCredentials(CustomCredentials cc)
        : base(cc)
    { }

    public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager()
    {
        return new CustomSecurityTokenManager(this);
    }

    protected override ClientCredentials CloneCore()
    {
        return new CustomCredentials(this);
    }
}

public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager
{
    public CustomSecurityTokenManager(CustomCredentials cred)
        : base(cred)
    { }

    public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version)
    {
        return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11);
    }
}

public class CustomTokenSerializer : WSSecurityTokenSerializer
{
    public CustomTokenSerializer(SecurityVersion sv)
        : base(sv)
    { }

    protected override void WriteTokenCore(System.Xml.XmlWriter writer,
                                            System.IdentityModel.Tokens.SecurityToken token)
    {
        UserNameSecurityToken userToken = token as UserNameSecurityToken;

        string tokennamespace = "o";

        DateTime created = DateTime.Now;
        string createdStr = created.ToString("yyyy-MM-ddTHH:mm:ss.fffZ");

        // unique Nonce value - encode with SHA-1 for 'randomness'
        // in theory the nonce could just be the GUID by itself
        string phrase = Guid.NewGuid().ToString();
        var nonce = GetSHA1String(phrase);

        // in this case password is plain text
        // for digest mode password needs to be encoded as:
        // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password))
        // and profile needs to change to
        //string password = GetSHA1String(nonce + createdStr + userToken.Password);

        string password = userToken.Password;

        writer.WriteRaw(string.Format(
        "<{0}:UsernameToken u:Id=\"" + token.Id +
        "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" +
        "<{0}:Username>" + userToken.UserName + "</{0}:Username>" +
        "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" +
        password + "</{0}:Password>" +
        "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" +
        nonce + "</{0}:Nonce>" +
        "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace));
    }

    protected string GetSHA1String(string phrase)
    {
        SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider();
        byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase));
        return Convert.ToBase64String(hashedDataBytes);
    }

}

Before creating the client, you create the custom binding and manually add the security, encoding and transport elements to it. Then, replace the default ClientCredentials with your custom implementation and set the username and password as you would normally:

var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement();
    security.IncludeTimestamp = false;
    security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256;
    security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

var encoding = new TextMessageEncodingBindingElement();
encoding.MessageVersion = MessageVersion.Soap11;

var transport = new HttpsTransportBindingElement();
transport.MaxReceivedMessageSize = 20000000; // 20 megs

binding.Elements.Add(security);
binding.Elements.Add(encoding);
binding.Elements.Add(transport);

RealTimeOnlineClient client = new RealTimeOnlineClient(binding,
    new EndpointAddress(url));

    client.ChannelFactory.Endpoint.EndpointBehaviors.Remove(client.ClientCredentials);
client.ChannelFactory.Endpoint.EndpointBehaviors.Add(new CustomCredentials());

client.ClientCredentials.UserName.UserName = username;
client.ClientCredentials.UserName.Password = password;

If you are using PHP 7.4 or above, you can use the spread operator ... as the following examples from the PHP Docs:

$arr1 = [1, 2, 3];
$arr2 = [...$arr1]; //[1, 2, 3]
$arr3 = [0, ...$arr1]; //[0, 1, 2, 3]
$arr4 = array(...$arr1, ...$arr2, 111); //[1, 2, 3, 1, 2, 3, 111]
$arr5 = [...$arr1, ...$arr1]; //[1, 2, 3, 1, 2, 3]

function getArr() {
  return ['a', 'b'];
}
$arr6 = [...getArr(), 'c']; //['a', 'b', 'c']

$arr7 = [...new ArrayIterator(['a', 'b', 'c'])]; //['a', 'b', 'c']

function arrGen() {
    for($i = 11; $i < 15; $i++) {
        yield $i;
    }
}
$arr8 = [...arrGen()]; //[11, 12, 13, 14]

It works like in JavaScript ES6.

See more on https://wiki.php.net/rfc/spread_operator_for_array.

before going to add a row, we have to convert the dataframe to dictionary there you can see the keys as columns in dataframe and values of the columns are again stored in the dictionary but there key for every column is the index number in dataframe. That idea make me to write the below code.

df2=df.to_dict()
values=["s_101","hyderabad",10,20,16,13,15,12,12,13,25,26,25,27,"good","bad"] #this is total row that we are going to add
i=0
for x in df.columns:   #here df.columns gives us the main dictionary key
    df2[x][101]=values[i]   #here the 101 is our index number it is also key of sub dictionary
    i+=1

Here is a handy function you can use to help with identifying your opencv matrices at runtime. I find it useful for debugging, at least.

string type2str(int type) {
  string r;

  uchar depth = type & CV_MAT_DEPTH_MASK;
  uchar chans = 1 + (type >> CV_CN_SHIFT);

  switch ( depth ) {
    case CV_8U:  r = "8U"; break;
    case CV_8S:  r = "8S"; break;
    case CV_16U: r = "16U"; break;
    case CV_16S: r = "16S"; break;
    case CV_32S: r = "32S"; break;
    case CV_32F: r = "32F"; break;
    case CV_64F: r = "64F"; break;
    default:     r = "User"; break;
  }

  r += "C";
  r += (chans+'0');

  return r;
}

If M is a var of type Mat you can call it like so:

string ty =  type2str( M.type() );
printf("Matrix: %s %dx%d \n", ty.c_str(), M.cols, M.rows );

Will output data such as:

Matrix: 8UC3 640x480 
Matrix: 64FC1 3x2 

Its worth noting that there are also Matrix methods Mat::depth() and Mat::channels(). This function is just a handy way of getting a human readable interpretation from the combination of those two values whose bits are all stored in the same value.

As @Arnab and @Mike pointed out, an array is not a list. Few differences are 1) arrays are fixed size during initialization 2) arrays normally support lesser operations than a list.

Maybe an overkill in most cases, but here is a basic 2d array implementation that leverages hardware array implementation using python ctypes(c libraries)

import ctypes
class Array:
    def __init__(self,size,foo): #foo is the initial value
        self._size = size
        ArrayType = ctypes.py_object * size
        self._array = ArrayType()
        for i in range(size):
            self._array[i] = foo
    def __getitem__(self,index):
        return self._array[index]
    def __setitem__(self,index,value):
        self._array[index] = value
    def __len__(self):
        return self._size

class TwoDArray:
    def __init__(self,columns,rows,foo):
        self._2dArray = Array(rows,foo)
        for i in range(rows):
            self._2dArray[i] = Array(columns,foo)

    def numRows(self):
        return len(self._2dArray)
    def numCols(self):
        return len((self._2dArray)[0])
    def __getitem__(self,indexTuple):
        row = indexTuple[0]
        col = indexTuple[1]
        assert row >= 0 and row < self.numRows() \
               and col >=0 and col < self.numCols(),\
               "Array script out of range"
        return ((self._2dArray)[row])[col]

if(__name__ == "__main__"):
    twodArray = TwoDArray(4,5,5)#sample input
    print(twodArray[2,3])

Change:

using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))

To:

 using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\Wow6432Node\MySQL AB\MySQL Connector\Net"))

While many people have pointed out that you can't execute dlls directly and should use rundll32.exe to execute exported functions instead, here is a screenshot of an actual dll file running just like an executable:

While you cannot run dll files directly, I suspect it is possible to run them from another process using a WinAPI function CreateProcess:

https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425(v=vs.85).aspx

I had the same issue. As this thread said, My table didn't have a PK, so I set the PK and ran the code. But unfortunately error came again. What I did next was, deleted the DB connection (delete .edmx file in Model folder of Solution Explorer) and recreated it. Error gone after that. Thanks everyone for sharing your experiences. It save lots of time.

Here's a variation I had to solve that's worth sharing: for each unique string in columnA I wanted to find the most common associated string in columnB.

df.groupby('columnA').agg({'columnB': lambda x: x.mode().any()}).reset_index()

The .any() picks one if there's a tie for the mode. (Note that using .any() on a Series of ints returns a boolean rather than picking one of them.)

For the original question, the corresponding approach simplifies to

df.groupby('columnA').columnB.agg('max').reset_index().

Can we see the structure of your table? If I am understanding this, then the assumption made by the query is that a record can be only meta_key - 'lat' or meta_key = 'long' not both because each row only has one meta_key column and can only contain 1 corresponding value, not 2. That would explain why you don't get results when you connect the with an AND; it's impossible.

Surround the string with <html></html> and break the lines with <br/>.

JLabel l = new JLabel("<html>Hello World!<br/>blahblahblah</html>", SwingConstants.CENTER);

db.employe.find({ $and:[ {"dept":{ $exists:false }, "empno": { $in:[101,102] } } ] }).count();

I think if you have something that structured and complex, you might consider something other than a single drop-down box.

I think the Python method insert is what you're looking for:

Inserts element x at position i. list.insert(i,x)

array = [1,2,3,4,5]

array.insert(1,20)

print(array)

# prints [1,2,20,3,4,5]

You can try this. its working for me 'name' is a property in arr.

repeat="item in (tagWordOptions | filter:{ name: $select.search } ) track by $index

This is a very old post, but I thought I should post my solution of a similar problem I faced recently.

Answer : I solved this issue by displaying the tr element as a block element i.e. specifying a CSS of display:block for the tr element. You can see this in code sample below.

<style>_x000D_
  tr {_x000D_
    display: block;_x000D_
    padding-bottom: 20px;_x000D_
  }_x000D_
  table {_x000D_

Or, building on Rusian L.'s suggestion, if the item you're searching for can be in the list more than once::

[Extension()]
public void ReplaceAll<T>(List<T> input, T search, T replace)
{
    int i = 0;
    do {
        i = input.FindIndex(i, s => EqualityComparer<T>.Default.Equals(s, search));

        if (i > -1) {
            FileSystem.input(i) = replace;
            continue;

Navigate to the "Get just the command line tools" section of the android downloads page, and download the tools for your system.

For Windows:

Extract the contents to C:\Android\android-sdk

Navigate to C:\Android\android-sdk\tools\bin and open a command line window
(shift + right click)

Run the following to download the latest android package:

sdkmanager "platforms;android-25" 

Update everything

sdkmanager --update

Other operation systems Do pretty much the same, but not using windows directories.

The sdkmanager page gives more info in to what commands to use to install your sdk.

It is not a big deal. you can simply put like this

WriteLine($"{DateTime.Now.ToString("yyyy-MM-dd-HH:mm:ss")}");

Excuse here for I used $ which is for string Interpolation .

In case you are doing it from Windows you can use Python script hivehoney to extract table data to local CSV file.

It will:

• Login to bastion host.
• pbrun.
• kinit.
• beeline (with your query).
• Save echo from beeline to a file on Windows.

Execute it like this:

set PROXY_HOST=your_bastion_host

set SERVICE_USER=you_func_user

set LINUX_USER=your_SOID

set LINUX_PWD=your_pwd

python hh.py --query_file=query.sql

You want to replace the Backslash?

Try stripcslashes:

The error Event the onerror handler receives is a simple event not containing such information:

If the user agent was required to fail the WebSocket connection or the WebSocket connection is closed with prejudice, fire a simple event named error at the WebSocket object.

You may have better luck listening for the close event, which is a CloseEvent and indeed has a CloseEvent.code property containing a numerical code according to RFC 6455 11.7 and a CloseEvent.reason string property.

Please note however, that CloseEvent.code (and CloseEvent.reason) are limited in such a way that network probing and other security issues are avoided.

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

I made custom messagebox using jquery UI component. Here is demo http://jsfiddle.net/eraj2587/Pm5Fr/14/

You have to pass just the parameters like caption name, message, button's text. You can specify trigger function on any button click. This will helpful for you.

function countbackgrounds() {
 var book = SpreadsheetApp.getActiveSpreadsheet();
 var sheet = book.getActiveSheet();
 var range_input = sheet.getRange("B3:B4");
 var range_output = sheet.getRange("B6");
 var cell_colors = range_input.getBackgroundColors();
 var color = "#58FA58";
 var count = 0;

 for(var r = 0; r < cell_colors.length; r++) {
   for(var c = 0; c < cell_colors[0].length; c++) {
     if(cell_colors[r][c] == color) {
       count = count + 1;
     }
   }
 }
    range_output.setValue(count);
 }

You can use geolocator.js for easily getting timezone and more...

It uses Google APIs that require a key. So, first you configure geolocator:

geolocator.config({
    language: "en",
    google: {
        version: "3",
        key: "YOUR-GOOGLE-API-KEY"
    }
});

Get TimeZone if you have the coordinates:

geolocator.getTimeZone(options, function (err, timezone) {
    console.log(err || timezone);
});

Example output:

{
    id: "Europe/Paris",
    name: "Central European Standard Time",
    abbr: "CEST",
    dstOffset: 0,
    rawOffset: 3600,
    timestamp: 1455733120
}

Locate then get TimeZone and more

If you don't have the coordinates, you can locate the user position first.

Example below will first try HTML5 Geolocation API to get the coordinates. If it fails or rejected, it will get the coordinates via Geo-IP look-up. Finally, it will get the timezone and more...

var options = {
    enableHighAccuracy: true,
    timeout: 6000,
    maximumAge: 0,
    desiredAccuracy: 30,
    fallbackToIP: true, // if HTML5 fails or rejected
    addressLookup: true, // this will get full address information
    timezone: true,
    map: "my-map" // this will even create a map for you
};
geolocator.locate(options, function (err, location) {
    console.log(err || location);
});

Example output:

{
    coords: {
        latitude: 37.4224764,
        longitude: -122.0842499,
        accuracy: 30,

You don't need - actually, can't "declare" variables in batch. Assigning a value to a variable creates it, and assigning an empty string deletes it. Any variable name that doesn't have an assigned value HAS a value of an empty string. ALL variables are strings - WITHOUT exception. There ARE operations that appear to perform (integer) mathematical functions, but they operate by converting back and forth from strings.

Batch is sensitive to spaces in variable names, so your assignment as posted would assign the string "A B C D" - including the quotes, to the variable "list " - NOT including the quotes, but including the space. The syntax set "var=string" is used to assign the value string to var whereas set var=string will do the same thing. Almost. In the first case, any stray trailing spaces after the closing quote are EXCLUDED from the value assigned, in the second, they are INCLUDED. Spaces are a little hard to see when printed.

ECHO echoes strings. Clasically, it is followed by a space - one of the default separators used by batch (the others are TAB, COMMA, SEMICOLON - any of these do just as well BUT TABS often get transformed to a space-squence by text-editors and the others have grown quirks of their own over the years.) Other characters following the O in ECHO have been found to do precisely what the documented SPACE should do. DOT is common. Open-parenthesis ( is probably the most useful since the command

ECHO.%emptyvalue%

will produce a report of the ECHO state (ECHO is on/off) whereas

ECHO(%emptyvalue%

will produce an empty line.

The problem with ECHO( is that the result "looks" unbalanced.

just need putting the datatype of the column in the datasource

dataSource: {
      data: empModel.Value,
      pageSize: 10,
      schema:  {
                model: {
                    fields: {
                        DOJ: { type: "date" }
                            }
                       }
               }  
           }

and then your statement column:

 columns: [
    {
        field: "Name",
        width: 90,
        title: "Name"
    },

    {
        field: "DOJ",
        width: 90,
        title: "DOJ",
        type: "date",
        format:"{0:MM-dd-yyyy}" 
    }
]

This worked for me:

export _JAVA_OPTIONS="-Xmx1g"

It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:

java -XshowSettings:vm 

and it will tell you:

Picked up _JAVA_OPTIONS: -Xmx1g

Raphaël supports this, with its Graffle example.

This answer is based off of Awais Akhtar's answer, and Vaibhav Jain's answer.

With the later spring-boot releases switching to Hikari can be done entirely in configuration. I'm using 1.5.6.RELEASE and this approach works.

build.gradle:

compile "com.zaxxer:HikariCP:2.7.3"

application YAML

spring:
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      idleTimeout: 60000
      minimumIdle: 2
      maximumPoolSize: 20
      connectionTimeout: 30000
      poolName: MyPoolName
      connectionTestQuery: SELECT 1

Change connectionTestQuery to suit your underlying DB. That's it, no code required.

For accessibility reason, I could not pull it off with multiple type=submit buttons. The only way to work natively with a form with multiple buttons but ONLY one can submit the form when hitting the Enter key is to ensure that only one of them is of type=submit while others are in other type such as type=button. By this way, you can benefit from the better user experience in dealing with a form on a browser in terms of keyboard support.

It's looking for an element with id list which has a property value equal to 2.
What you want is the option child of the list:

$("#list option[value='2']").text()

Use %0D%0A for a line break in your body

• How to enter line break into mailto body command (by Christian Petters; 01 Apr 2008)

Example (Demo):

<a href="mailto:[email protected]?subject=Suggestions&body=name:%0D%0Aemail:">test</a>?
                                                                  ^^^^^^

strong: assigns the incoming value to it, it will retain the incoming value and release the existing value of the instance variable

weak: will assign the incoming value to it without retaining it.

So the basic difference is the retaining of the new variable. Generaly you want to retain it but there are situations where you don't want to have it otherwise you will get a retain cycle and can not free the memory the objects. Eg. obj1 retains obj2 and obj2 retains obj1. To solve this kind of situation you use weak references.

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

1. validating the data POSTed

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

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

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

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

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

You have to create your own log4j.properties in the classpath folder.

I also faced this error but I was not working behind a proxy server at the moment so using npm config set proxy=http://address:8080 couldn't help and ~/.npmrc didn't contain any proxy setting either. The solution in my case was just to restart my computer.

An async call to see if a file exists is the better approach, because it doesn't degrade the user experience by waiting for a response from the server. If you make a call to .open with the third parameter set to false (as in many examples above, for example http.open('HEAD', url, false); ), this is a synchronous call, and you get a warning in the browser console.

A better approach is:

function fetchStatus( address ) {
  var client = new XMLHttpRequest();
  client.onload = function() {
    // in case of network errors this might not give reliable results
    returnStatus( this.status );
  }
  client.open( "HEAD", address, true );
  client.send();
}

function returnStatus( status ) {
  if ( status === 200 ) {
    console.log( 'file exists!' );
  }
  else {
    console.log( 'file does not exist! status: ' + status );
  }
}

You're looking for:

.is(':visible')

Although you should probably change your selector to use jQuery considering you're using it in other places anyway:

if($('#testElement').is(':visible')) {
    // Code
}

It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible') on the child will return false (which makes sense).

jQuery 3

:visible has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible):

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle():

function toggleTestElement() {
    $('#testElement').fadeToggle('fast');
}

this worked for me.

change varchar column to int

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

This should get you for starting with two letters and ending with two numbers.

[A-Za-z]{2}(.*)[0-9]{2}

If you know it will always be just two and two you can

[A-Za-z]{2}[0-9]{2}

Use subshell:

echo "$(echo -n 'hello'; cat filename)" > filename

Unfortunately, command substitution will remove newlines at the end of file. So as to keep them one can use:

echo -n "hello" | cat - filename > /tmp/filename.tmp
mv /tmp/filename.tmp filename

Neither grouping nor command substitution is needed.

The WPF TestApi library comes with one of the nicest command line parsers for C# development. I highly recommend looking into it, from Ivo Manolov's blog on the API:

// EXAMPLE #2:
// Sample for parsing the following command-line:
// Test.exe /verbose /runId=10
// This sample declares a class in which the strongly-
// typed arguments are populated
public class CommandLineArguments
{
   bool? Verbose { get; set; }
   int? RunId { get; set; }
}

CommandLineArguments a = new CommandLineArguments();
CommandLineParser.ParseArguments(args, a);

Order of iterators may seem counter-intuitive.

Take for example: [str(x) for i in range(3) for x in foo(i)]

Let's decompose it:

def foo(i):
    return i, i + 0.5

[str(x)
    for i in range(3)
        for x in foo(i)
]

# is same as
for i in range(3):
    for x in foo(i):
        yield str(x)

Java 8

As integers are comparable we can use the following one liner in:

List<Integer> ints = Stream.of(22,44,11,66,33,55).collect(Collectors.toList());
Integer max = ints.stream().mapToInt(i->i).max().orElseThrow(NoSuchElementException::new); //66
Integer min = ints.stream().mapToInt(i->i).min().orElseThrow(NoSuchElementException::new); //11

Another point to note is we cannot use Funtion.identity() in place of i->i as mapToInt expects ToIntFunction which is a completely different interface and is not related to Function. Moreover this interface has only one method applyAsInt and no identity() method.

toISOString() will return current UTC time only not the current local time. If you want to get the current local time in yyyy-MM-ddTHH:mm:ss.SSSZ format then you should get the current time using following two methods

Method 1:

document.write(new Date(new Date().toString().split('GMT')[0]+' UTC').toISOString());

Method 2:

document.write(new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString());

Equivalent will be

ADD_MONTHS( SYSDATE, -6 )

I've had the same problem too. Searched everywhere online and can't find a solution. I did install Redgate's SQL Prompt which functions similarly to Intellisense, so maybe there was a conflict. I've since stopped the Prompt from running, but now no intellisense at all. Using SQL Server 2008 will SQLCMD mode off, no luck at all. This has happened before, a reinstall of SQL Server was the only thing that I could get to work.

I came across this post searching how to add an extra directory for resources. I found a solution that may be useful to someone. Here is my final configuration to get that:

sourceSets {
    main {
        resources {
            srcDirs "src/main/resources", "src/main/configs"
        }
    }
}

You can use [[UINavigationBar appearance] setTintColor:myColor];

Since iOS 7 you need to set [[UINavigationBar appearance] setBarTintColor:myColor]; and also [[UINavigationBar appearance] setTranslucent:NO].

[[UINavigationBar appearance] setBarTintColor:myColor];
[[UINavigationBar appearance] setTranslucent:NO];

Here is a class that can be used to setup and run ordered tests independent of MS Ordered Tests framework for whatever reason--like not have to adjust mstest.exe arguments on a build machine, or mixing ordered with non-ordered in a class.

The original testing framework only sees the list of ordered tests as a single test so any init/cleanup like [TestInitalize()] Init() is only called before and after the entire set.

Usage:

        [TestMethod] // place only on the list--not the individuals
        public void OrderedStepsTest()
        {
            OrderedTest.Run(TestContext, new List<OrderedTest>
            {
                new OrderedTest ( T10_Reset_Database, false ),
                new OrderedTest ( T20_LoginUser1, false ),
                new OrderedTest ( T30_DoLoginUser1Task1, true ), // continue on failure
                new OrderedTest ( T40_DoLoginUser1Task2, true ), // continue on failure
                // ...
            });                
        }

jQuery's empty() function does just that:

$('#masterdiv').empty();

clears the master div.

$('#masterdiv div').empty();

clears all the child divs, but leaves the master intact.

Try this:

setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);

It will work.

Had a similar problem, where I had to set the form back to pristine, but also to untouched, since $invalid and $error were both used to show error messages. Only using setPristine() was not enough to clear the error messages.

I solved it by using setPristine() and setUntouched(). (See Angular's documentation: https://docs.angularjs.org/api/ng/type/ngModel.NgModelController)

So, in my controller, I used:

$scope.form.setPristine(); 
$scope.form.setUntouched();

These two functions reset the complete form to $pristine and back to $untouched, so that all error messages were cleared.

Latest version of SpringBoot makes uploading multiple files very easy also. On the browser side you just need the standard HTML upload form, but with multiple input elements (one per file to upload, which is very important), all having the same element name (name="files" for the example below)

Then in your Spring @Controller class on the server all you need is something like this:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
    public @ResponseBody ResponseEntity<?> upload(
        @RequestParam("files") MultipartFile[] uploadFiles) throws Exception     
{
    ...now loop over all uploadFiles in the array and do what you want
  return new ResponseEntity<>(HttpStatus.OK);
}

Those are the tricky parts. That is, knowing to create multiple input elements each named "files", and knowing to use a MultipartFile[] (array) as the request parameter are the tricky things to know, but it's just that simple. I won't get into how to process a MultipartFile entry, because there's plenty of docs on that already.

There are 3 ways to achieve this as shown below

Method 1:

var uName="abc";
var passwrd="pqr";

$.ajax({
    type: '{GET/POST}',
    url: '{urlpath}',
    headers: {
        "Authorization": "Basic " + btoa(uName+":"+passwrd);
    },
    success : function(data) {
      //Success block  
    },
   error: function (xhr,ajaxOptions,throwError){
    //Error block 
  },
});

Method 2:

var uName="abc";
var passwrd="pqr";

$.ajax({
    type: '{GET/POST}',
    url: '{urlpath}',
     beforeSend: function (xhr){ 
        xhr.setRequestHeader('Authorization', "Basic " + btoa(uName+":"+passwrd)); 
    },
    success : function(data) {
      //Success block 
   },
   error: function (xhr,ajaxOptions,throwError){
    //Error block 
  },
});

Method 3:

var uName="abc";
var passwrd="pqr";

$.ajax({
    type: '{GET/POST}',
    url: '{urlpath}',
    username:uName,
    password:passwrd, 
    success : function(data) {
    //Success block  
   },
    error: function (xhr,ajaxOptions,throwError){
    //Error block 
  },
});

an example from my database table name sensor with colums (id,time,unit)

select ('id') as id, ('time') as time, ('unit') as unit
UNION ALL
SELECT * INTO OUTFILE 'C:/Users/User/Downloads/data.csv'
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\n'
  FROM sensor

This can happen due to a different language in the phone for which your code doesn't have the asset for. For example your preference.xml is placed in xml-en and you are trying to run your app in a phone which has French selected, the app will crash.

Use this Retrofit Client

class RetrofitClient2(context: Context) : OkHttpClient() {

    private var mContext:Context = context
    private var retrofit: Retrofit? = null

    val client: Retrofit?
        get() {
            val logging = HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)

            val client = OkHttpClient.Builder()
                    .connectTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
                    .readTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
                    .writeTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
            client.addInterceptor(logging)
            client.interceptors().add(AddCookiesInterceptor(mContext))

            val gson = GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").create()
            if (retrofit == null) {

                retrofit = Retrofit.Builder()
                        .baseUrl(Constants.URL)
                        .addConverterFactory(GsonConverterFactory.create(gson))
                        .client(client.build())
                        .build()
            }
            return retrofit
        }
}

I'm passing the JWT along with every request. Please don't mind the variable names, it's a bit confusing.

class AddCookiesInterceptor(context: Context) : Interceptor {
    val mContext: Context = context
    @Throws(IOException::class)
    override fun intercept(chain: Interceptor.Chain): Response {
        val builder = chain.request().newBuilder()
        val preferences = CookieStore().getCookies(mContext)
        if (preferences != null) {
            for (cookie in preferences!!) {
                builder.addHeader("Authorization", cookie)
            }
        }
        return chain.proceed(builder.build())
    }
}

Please set http content type in header and also make sure the server is authenticating CORS. This is how to do it in PHP:

//NOT A TESTED CODE
header('Content-Type: application/json;charset=UTF-8');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: DELETE, HEAD, GET, OPTIONS, POST, PUT');
header('Access-Control-Allow-Headers: Content-Type, Content-Range, Content-Disposition, Content-Description');
header('Access-Control-Max-Age: 1728000');

Please refer to:

http://www.w3.org/TR/cors/#cross-origin-request-with-preflight-0

How does Access-Control-Allow-Origin header work?

The default behaviour of Newtonsoft.Json is going to find the public constructors. If your default constructor is only used in containing class or the same assembly, you can reduce the access level to protected or internal so that Newtonsoft.Json will pick your desired public constructor.

Admittedly, this solution is rather very limited to specific cases.

internal Result() { }

public Result(int? code, string format, Dictionary<string, string> details = null)
{
    Code = code ?? ERROR_CODE;
    Format = format;

    if (details == null)
        Details = new Dictionary<string, string>();
    else
        Details = details;
}

Uncaught InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number

Means you are not passing numbers into the google.maps.LatLng constructor. Per your comment:

/*Information from chromium debugger
trader: Object
    geo: Object
        lat: "49.014821"
        lon: "10.985072"

*/

trader.geo.lat and trader.geo.lon are strings, not numbers. Use parseFloat to convert them to numbers:

var myLatlng = new google.maps.LatLng(parseFloat(trader.geo.lat),parseFloat(trader.geo.lon));

In Maven: The Definitive Guide, I wrote about the differences between Maven and Ant in the introduction the section title is "The Differences Between Ant and Maven". Here's an answer that is a combination of the info in that introduction with some additional notes.

A Simple Comparison

I'm only showing you this to illustrate the idea that, at the most basic level, Maven has built-in conventions. Here's a simple Ant build file:

<project name="my-project" default="dist" basedir=".">
    <description>
        simple example build file
    </description>   
    <!-- set global properties for this build -->   
    <property name="src" location="src/main/java"/>
    <property name="build" location="target/classes"/>
    <property name="dist"  location="target"/>

    <target name="init">
      <!-- Create the time stamp -->
      <tstamp/>
      <!-- Create the build directory structure used by compile -->
      <mkdir dir="${build}"/>   
    </target>

    <target name="compile" depends="init"
        description="compile the source " >
      <!-- Compile the java code from ${src} into ${build} -->
      <javac srcdir="${src}" destdir="${build}"/>  
    </target>

    <target name="dist" depends="compile"
        description="generate the distribution" >
      <!-- Create the distribution directory -->
      <mkdir dir="${dist}/lib"/>

      <!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file
-->
      <jar jarfile="${dist}/lib/MyProject-${DSTAMP}.jar" basedir="${build}"/>
   </target>

   <target name="clean"
        description="clean up" >
     <!-- Delete the ${build} and ${dist} directory trees -->
     <delete dir="${build}"/>
     <delete dir="${dist}"/>
   </target>
 </project>

In this simple Ant example, you can see how you have to tell Ant exactly what to do. There is a compile goal which includes the javac task that compiles the source in the src/main/java directory to the target/classes directory. You have to tell Ant exactly where your source is, where you want the resulting bytecode to be stored, and how to package this all into a JAR file. While there are some recent developments that help make Ant less procedural, a developer's experience with Ant is in coding a procedural language written in XML.

Contrast the previous Ant example with a Maven example. In Maven, to create a JAR file from some Java source, all you need to do is create a simple pom.xml, place your source code in ${basedir}/src/main/java and then run mvn install from the command line. The example Maven pom.xml that achieves the same results.

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.sonatype.mavenbook</groupId>
  <artifactId>my-project</artifactId>
  <version>1.0</version>
</project>

That's all you need in your pom.xml. Running mvn install from the command line will process resources, compile source, execute unit tests, create a JAR, and install the JAR in a local repository for reuse in other projects. Without modification, you can run mvn site and then find an index.html file in target/site that contains links to JavaDoc and a few reports about your source code.

Admittedly, this is the simplest possible example project. A project which only contains source code and which produces a JAR. A project which follows Maven conventions and doesn't require any dependencies or customization. If we wanted to start customizing the behavior, our pom.xml is going to grow in size, and in the largest of projects you can see collections of very complex Maven POMs which contain a great deal of plugin customization and dependency declarations. But, even when your project's POM files become more substantial, they hold an entirely different kind of information from the build file of a similarly sized project using Ant. Maven POMs contain declarations: "This is a JAR project", and "The source code is in src/main/java". Ant build files contain explicit instructions: "This is project", "The source is in src/main/java", "Run javac against this directory", "Put the results in target/classses", "Create a JAR from the ....", etc. Where Ant had to be explicit about the process, there was something "built-in" to Maven that just knew where the source code was and how it should be processed.

High-level Comparison

The differences between Ant and Maven in this example? Ant...

• doesn't have formal conventions like a common project directory structure, you have to tell Ant exactly where to find the source and where to put the output. Informal conventions have emerged over time, but they haven't been codified into the product.
• is procedural, you have to tell Ant exactly what to do and when to do it. You had to tell it to compile, then copy, then compress.
• doesn't have a lifecycle, you had to define goals and goal dependencies. You had to attach a sequence of tasks to each goal manually.

Where Maven...

• has conventions, it already knew where your source code was because you followed the convention. It put the bytecode in target/classes, and it produced a JAR file in target.
• is declarative. All you had to do was create a pom.xml file and put your source in the default directory. Maven took care of the rest.
• has a lifecycle, which you invoked when you executed mvn install. This command told Maven to execute a series of sequence steps until it reached the lifecycle. As a side-effect of this journey through the lifecycle, Maven executed a number of default plugin goals which did things like compile and create a JAR.

What About Ivy?

Right, so someone like Steve Loughran is going to read that comparison and call foul. He's going to talk about how the answer completely ignores something called Ivy and the fact that Ant can reuse build logic in the more recent releases of Ant. This is true. If you have a bunch of smart people using Ant + antlibs + Ivy, you'll end up with a well designed build that works. Even though, I'm very much convinced that Maven makes sense, I'd happily use Ant + Ivy with a project team that had a very sharp build engineer. That being said, I do think you'll end up missing out on a number of valuable plugins such as the Jetty plugin and that you'll end up doing a whole bunch of work that you didn't need to do over time.

More Important than Maven vs. Ant

1. Is that you use a Repository Manager to keep track of software artifacts. I'd suggest downloading Nexus. You can use Nexus to proxy remote repositories and to provide a place for your team to deploy internal artifacts.
2. You have appropriate modularization of software components. One big monolithic component rarely scales over time. As your project develops, you'll want to have the concept of modules and sub-modules. Maven lends itself to this approach very well.
3. You adopt some conventions for your build. Even if you use Ant, you should strive to adopt some form of convention that is consistent with other projects. When a project uses Maven, it means that anyone familiar with Maven can pick up the build and start running with it without having to fiddle with configuration just to figure out how to get the thing to compile.

There isn't from a hyperlink, no. Not unless the page has script inside specifically for this and it's checking for some parameter....but for your question, no, there's no built-in support in browsers for this.

There are however bookmarklets you can bookmark to quickly run JavaScript functions from your address bar; not sure if that meets your needs, but it's as close as it gets.

This is really easy using jQuery.

For instance:

$(".left").mouseover(function(){$(".left1").show()});
$(".left").mouseout(function(){$(".left1").hide()});

I've update your fiddle: http://jsfiddle.net/TqDe9/2/

1. First declare the marker:

this.marker = new google.maps.Marker({
   position: new google.maps.LatLng(12.924640523603115,77.61965398949724),
   map: map
});

2. Call the method to plot the marker on click:

this.placeMarker(coordinates, this.map);

3. Define the function:

placeMarker(location, map) {
    var marker = new google.maps.Marker({
        position: location,
        map: map
    });
    this.markersArray.push(marker);
}

Use listboxControl.Column(intColumn,intRow). Both Column and Row are zero-based.

If you are not using the transferTo feature or non-blocking features you will not notice a difference between traditional IO and NIO(2) because the traditional IO maps to NIO.

But if you can use the NIO features like transferFrom/To or want to use Buffers, then of course NIO is the way to go.

SELECT COUNT(1) FROM MyTable WHERE ...

will loop thru all the records. This is the reason it is bad to use for record existence.

I would use

SELECT TOP 1 * FROM MyTable WHERE ...

After finding 1 record, it will terminate the loop.

Say you want Comic Sans for the title and Helvetica for the x label.

csfont = {'fontname':'Comic Sans MS'}
hfont = {'fontname':'Helvetica'}

plt.title('title',**csfont)
plt.xlabel('xlabel', **hfont)
plt.show()

What you can do is use delimeter as new line. Till you press enter key you will be able to read it as string.

Scanner sc = new Scanner(System.in);
sc.useDelimiter(System.getProperty("line.separator"));

Hope this helps.

It works, in my case for Xcode from 7.3 TO 7.1. Copy directory 9.2, for iOS device OS 9.2.1.

I think the following would work well with lesser line of codes.

        session()->flash('toast', [
        'status' => 'success', 
        'body' => 'Body',
        'topic' => 'Success']
    );

I'm using a toaster package, but you can have something like this in your view.

             toastr.{{session('toast.status')}}(
              '{{session('toast.body')}}', 
              '{{session('toast.topic')}}'
             );

If you want to keep only numbers then use /[^0-9]+/ instead of /[^a-zA-Z]+/

In general

vcvarsall.bat is part of the Visual C++ compiler, you need that to install what you are trying to install. Don't even try to deal with MingGW if your Python was compiled with Visual Studio toolchain and vice versa. Even the version of the Microsoft tool chain is important. Python compiled with VS 2008 won't work with extensions compiled with VS 2010!

You have to compile PyCrypto with the same compiler that the version of Python was compiled with. Google for "Unable to find vcvarsall.bat" because that is the root of your problem, it is a very common problem with compiling Python extensions on Windows.

There is a lot of information and a lot to read to get this right on whatever system you are on with this link.

Beware using Visual Studio 2010 or not using Visual Studio 2008

As far as I know the following is still true. This was posted in the link above in June, 2010 referring to trying to build extensions with VS 2010 Express against the Python installers available on python.org.

Be careful if you do this. Python 2.6 and 2.7 from python.org are built with Visual Studio 2008 compilers. You will need to link with the same CRT (msvcr90.dll) as Python.

Visual Studio 2010 Express links with the wrong CRT version: msvcr100.dll.

If you do this, you must also re-build Python with Visual Studio 2010 Express. You cannot use the standard Python binary installer for Windows. Nor can you use any C/C++ extensions built with a different compiler than Visual Studio 2010 (Express).

Opinion: This is one reason I abandoned Windows for all serious development work for OSX!

In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
     int int_a = * ( (int*) a );
     int int_b = * ( (int*) b );

     if ( int_a == int_b ) return 0;
     else if ( int_a < int_b ) return -1;
     else return 1;
}

qsort( a, 6, sizeof(int), compare )

see: http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/

To answer the second part of your question: an optimal (comparison based) sorting algorithm is one that runs with O(n log(n)) comparisons. There are several that have this property (including quick sort, merge sort, heap sort, etc.), but which one to use depends on your use case.

As a side note, you can sometime do better than O(n log(n)) if you know something about your data - see the wikipedia article on Radix Sort

You can also use

[AnyClass].class.getResource(filePath)

You need to do .button("refresh")

HTML :

<button id='btnviewdetails' type='button'>SET</button>

JS :

$('#btnviewdetails').text('Save').button("refresh");

No, TRUNCATE is all or nothing. You can do a DELETE FROM <table> WHERE <conditions> but this loses the speed advantages of TRUNCATE.

__call__ makes any object be callable as a function.

This example will output 8:

class Adder(object):
  def __init__(self, val):
    self.val = val

  def __call__(self, val):
    return self.val + val

func = Adder(5)
print func(3)

you can use the example from Microsoft - for you without namespace:

using System.Xml.Linq;
using System.Xml.XPath;
var e = xdoc.XPathSelectElement("./Report/ReportInfo/Name");     

should do it

If you want to pretty print the data frames, then you can use tabulate package.

import pandas as pd
import numpy as np
from tabulate import tabulate

def pprint_df(dframe):
    print tabulate(dframe, headers='keys', tablefmt='psql', showindex=False)

df = pd.DataFrame({'col1': np.random.randint(0, 100, 10), 
    'col2': np.random.randint(50, 100, 10), 
    'col3': np.random.randint(10, 10000, 10)})

pprint_df(df)

Specifically, the showindex=False, as the name says, allows you to not show index. The output would look as follows:

+--------+--------+--------+
|   col1 |   col2 |   col3 |
|--------+--------+--------|
|     15 |     76 |   5175 |
|     30 |     97 |   3331 |
|     34 |     56 |   3513 |
|     50 |     65 |    203 |
|     84 |     75 |   7559 |
|     41 |     82 |    939 |
|     78 |     59 |   4971 |
|     98 |     99 |    167 |
|     81 |     99 |   6527 |
|     17 |     94 |   4267 |
+--------+--------+--------+

You are using an $id variable in your model, but your are plucking it from nowhere. You need to pass the $id variable from your controller to your model.

Controller

Lets pass the $id to the model via a parameter of the row_delete() method.

function delete_row()
{
   $this->load->model('mod1');

   // Pass the $id to the row_delete() method
   $this->mod1->row_delete($id);


   redirect($_SERVER['HTTP_REFERER']);  
}

Model

Add the $id to the Model methods parameters.

function row_delete($id)
{
   $this->db->where('id', $id);
   $this->db->delete('testimonials'); 
}

The problem now is that your passing the $id variable from your controller, but it's not declared anywhere in your controller.

The tutorial you saw was telling you how to exit nano editor. By typing Ctrl+X nano exits and if your file needs change you will be prompted to save the changes in which case to save you should press Y and then enter to save changes in the same file you open.

If you are not using any gui and you just want to leave the shell the command is Ctrl+D.

Regarding tutorial, The Linux Documentation Project would be a good place to start. If you like books I would recommend by far any book you want from O'Reilly. They have nice cd bookshelfs with good compilation for any linux sysadmin, and without much effort you can find many places where those html bookshelfs are available to read online.

When you populate your fields, you can check for the value:

<input type="radio" name="sex" value="Male" <?php echo ($sex=='Male')?'checked':'' ?>size="17">Male
<input type="radio" name="sex" value="Female" <?php echo ($sex=='Female')?'checked':'' ?> size="17">Female

Assuming that the value you return from your database is in the variable $sex

The checked property will preselect the value that match

use a negative character class:

[^,;]+

I use Windows 10 machine working with PHP 8 and Lavarel 8 and I got the same error, I used the following command :-

composer update --ignore-platform-reqs

to update all the packages regardless of the version conflicts.

No, it is not okay to put a link element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):

“This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.”

Just problem with the class generating step. You can go to the project folder by explorer and delete classes. After that run "build" your project again. Now, your problem is fixed

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

Likely the shortest code using the String API, exclusively:

String space10 = new String(new char[10]).replace('\0', ' ');

System.out.println("[" + space10 + "]");
// prints "[          ]"

As a method, without directly instantiating char:

import java.nio.CharBuffer;

/**
 * Creates a string of spaces that is 'spaces' spaces long.
 *
 * @param spaces The number of spaces to add to the string.
 */
public String spaces( int spaces ) {
  return CharBuffer.allocate( spaces ).toString().replace( '\0', ' ' );
}

Invoke using:

System.out.printf( "[%s]%n", spaces( 10 ) );

Simply write one line in the constructor:

setResizable(false);

This will make it impossible to resize the frame.

Using parents('tr').hide() works. However if there is an embedded table, all parent tr rows will be hidden. In my case, the entire form is hidden since there are many embedded tables.

using pywin32:

from win32com.client import Dispatch

session = Dispatch('MAPI.session')
session.Logon('','',0,1,0,0,'exchange.foo.com\nUserName');
msg = session.Outbox.Messages.Add('Hello', 'This is a test')
msg.Recipients.Add('Corey', 'SMTP:[email protected]')
msg.Send()
session.Logoff()

You can use Newtonsoft.Json, it's a dependency of Microsoft.AspNet.Mvc.ModelBinding which is a dependency of Microsoft.AspNet.Mvc. So, you don't need to add a dependency in your project.json.

#using Newtonsoft.Json
....
JsonConvert.DeserializeObject(json);

Note, using a WebAPI controller you don't need to deal with JSON.

UPDATE ASP.Net Core 3.0

Json.NET has been removed from the ASP.NET Core 3.0 shared framework.

You can use the new JSON serializer layers on top of the high-performance Utf8JsonReader and Utf8JsonWriter. It deserializes objects from JSON and serializes objects to JSON. Memory allocations are kept minimal and includes support for reading and writing JSON with Stream asynchronously.

To get started, use the JsonSerializer class in the System.Text.Json.Serialization namespace. See the documentation for information and samples.

To use Json.NET in an ASP.NET Core 3.0 project:

• Add a package reference to Microsoft.AspNetCore.Mvc.NewtonsoftJson
• Update ConfigureServices to call AddNewtonsoftJson().

    services.AddMvc()
        .AddNewtonsoftJson();

Read Json.NET support in Migrate from ASP.NET Core 2.2 to 3.0 Preview 2 for more information.

Let's discuss why an "object not found" error can be thrown in R in addition to explaining what it means. What it means (to many) is obvious: the variable in question, at least according to the R interpreter, has not yet been defined, but if you see your object in your code there can be multiple reasons for why this is happening:

1. check syntax of your declarations. If you mis-typed even one letter or used upper case instead of lower case in a later calling statement, then it won't match your original declaration and this error will occur.

2. Are you getting this error in a notebook or markdown document? You may simply need to re-run an earlier cell that has your declarations before running the current cell where you are calling the variable.

3. Are you trying to knit your R document and the variable works find when you run the cells but not when you knit the cells? If so - then you want to examine the snippet I am providing below for a possible side effect that triggers this error:

   {r sourceDataProb1, echo=F, eval=F} # some code here

The above snippet is from the beginning of an R markdown cell. If eval and echo are both set to False this can trigger an error when you try to knit the document. To clarify. I had a use case where I had left these flags as False because I thought i did not want my code echoed or its results to show in the markdown HTML I was generating. But since the variable was then used in later cells, this caused an error during knitting. Simple trial and error with T/F TRUE/FALSE flags can establish if this is the source of your error when it occurs in knitting an R markdown document from RStudio.

Lastly: did you remove the variable or clear it from memory after declaring it?

• rm() removes the variable
• hitting the broom icon in the evironment window of RStudio clearls everything in the current working environment
• ls() can help you see what is active right now to look for a missing declaration.
• exists("x") - as mentioned by another poster, can help you test a specific value in an environment with a very lengthy list of active variables

The operation is not allowed in chrome. You can either use a HTTP server(Tomcat) or you use Firefox instead.

I solve this problem, the reason is: You downloaded other's projects. His local.properties file content is his SDK path. You must replace SDK path with your local SDK path, then rebuild the project.

If you have to load a lot of data into tables on a regular basis, check out SQL Loader or external tables. Should be much faster than individual Inserts.

I implemented a function similar to the momentjs method subtract.

- If you use Javascript

function addDate(dt, amount, dateType) {
  switch (dateType) {
    case 'days':
      return dt.setDate(dt.getDate() + amount) && dt;
    case 'weeks':
      return dt.setDate(dt.getDate() + (7 * amount)) && dt;
    case 'months':
      return dt.setMonth(dt.getMonth() + amount) && dt;
    case 'years':
      return dt.setFullYear( dt.getFullYear() + amount) && dt;
  }
}

example:

let dt = new Date();
dt = addDate(dt, -1, 'months');// use -1 to subtract 

- If you use Typescript:

export enum dateAmountType {
  DAYS,
  WEEKS,
  MONTHS,
  YEARS,
}

export function addDate(dt: Date, amount: number, dateType: dateAmountType): Date {
  switch (dateType) {
    case dateAmountType.DAYS:
      return dt.setDate(dt.getDate() + amount) && dt;
    case dateAmountType.WEEKS:
      return dt.setDate(dt.getDate() + (7 * amount)) && dt;
    case dateAmountType.MONTHS:
      return dt.setMonth(dt.getMonth() + amount) && dt;
    case dateAmountType.YEARS:
      return dt.setFullYear( dt.getFullYear() + amount) && dt;
  }
}

example:

let dt = new Date();
dt = addDate(dt, -1, 'months'); // use -1 to subtract

Optional (unit-tests)

I also made some unit-tests for this function using Jasmine:

  it('addDate() should works properly', () => {
    for (const test of [
      { amount: 1,  dateType: dateAmountType.DAYS,   expect: '2020-04-13'},
      { amount: -1, dateType: dateAmountType.DAYS,   expect: '2020-04-11'},
      { amount: 1,  dateType: dateAmountType.WEEKS,  expect: '2020-04-19'},
      { amount: -1, dateType: dateAmountType.WEEKS,  expect: '2020-04-05'},
      { amount: 1,  dateType: dateAmountType.MONTHS, expect: '2020-05-12'},
      { amount: -1, dateType: dateAmountType.MONTHS, expect: '2020-03-12'},
      { amount: 1,  dateType: dateAmountType.YEARS,  expect: '2021-04-12'},
      { amount: -1, dateType: dateAmountType.YEARS,  expect: '2019-04-12'},
    ]) {
      expect(formatDate(addDate(new Date('2020-04-12'), test.amount, test.dateType))).toBe(test.expect);
    }

  });

To use this test you need this function:

// get format date as 'YYYY-MM-DD'
export function formatDate(date: Date): string {
  const d     = new Date(date);
  let month   = '' + (d.getMonth() + 1);
  let day     = '' + d.getDate();
  const year  = d.getFullYear();

  if (month.length < 2)  {
    month = '0' + month;
  }
  if (day.length < 2) {
    day = '0' + day;
  }

  return [year, month, day].join('-');
}

The PostgreSQL manual indicates that this means the transaction is open (inside BEGIN) and idle. It's most likely a user connected using the monitor who is thinking or typing. I have plenty of those on my system, too.

If you're using Slony for replication, however, the Slony-I FAQ suggests idle in transaction may mean that the network connection was terminated abruptly. Check out the discussion in that FAQ for more details.

The below snippet examines EAX using GDB.

    (gdb) info register eax
    eax            0xaa55   43605
    (gdb) info register ax
    ax             0xaa55   -21931
    (gdb) info register ah
    ah             0xaa -86
    (gdb) info register al
    al             0x55 85

1. EAX - Full 32 bit value
2. AX - lower 16 bit value
3. AH - Bits from 8 to 15
4. AL - lower 8 bits of EAX/AX

You can put expressions inside braces. Notice in the compiled JavaScript why a for loop would never be possible inside JSX syntax; JSX amounts to function calls and sugared function arguments. Only expressions are allowed.

(Also: Remember to add key attributes to components rendered inside loops.)

JSX + ES2015:

render() {
  return (
    <table className="MyClassName">
      <thead>
        <tr>
          {this.props.titles.map(title =>
            <th key={title}>{title}</th>
          )}
        </tr>
      </thead>
      <tbody>
        {this.props.rows.map((row, i) =>
          <tr key={i}>
            {row.map((col, j) =>
              <td key={j}>{col}</td>
            )}
          </tr>
        )}
      </tbody>
    </table>
  );
} 

JavaScript:

render: function() {
  return (
    React.DOM.table({className: "MyClassName"}, 
      React.DOM.thead(null, 
        React.DOM.tr(null, 
          this.props.titles.map(function(title) {
            return React.DOM.th({key: title}, title);
          })
        )
      ), 
      React.DOM.tbody(null, 
        this.props.rows.map(function(row, i) {
          return (
            React.DOM.tr({key: i}, 
              row.map(function(col, j) {
                return React.DOM.td({key: j}, col);
              })
            )
          );
        })
      )
    )
  );
} 

git gc --aggressive is one way to force the prune process to take place (to be sure: git gc --aggressive --prune=now). You have other commands to clean the repo too. Don't forget though, sometimes git gc alone can increase the size of the repo!

It can be also used after a filter-branch, to mark some directories to be removed from the history (with a further gain of space); see here. But that means nobody is pulling from your public repo. filter-branch can keep backup refs in .git/refs/original, so that directory can be cleaned too.

Finally, as mentioned in this comment and this question; cleaning the reflog can help:

git reflog expire --all --expire=now
git gc --prune=now --aggressive

An even more complete, and possibly dangerous, solution is to remove unused objects from a git repository

Update Feb. 2021, eleven years later: the new git maintenance command (man page) should supersede git gc, and can be scheduled.

In applied usage for the Asynchronous IO coroutine, yield from has a similar behavior as await in a coroutine function. Both of which is used to suspend the execution of coroutine.

• yield from is used by the generator-based coroutine.

• await is used for async def coroutine. (since Python 3.5+)

For Asyncio, if there's no need to support an older Python version (i.e. >3.5), async def/await is the recommended syntax to define a coroutine. Thus yield from is no longer needed in a coroutine.

But in general outside of asyncio, yield from <sub-generator> has still some other usage in iterating the sub-generator as mentioned in the earlier answer.

If you are using node.js you can do this:

yourByteArray.toString('base64');

No.

Little bit off topic but say i want to remove all 2s from a list. Here's a very elegant way to do that.

void RemoveAll<T>(T item,List<T> list)
{
    while(list.Contains(item)) list.Remove(item);
}

With predicate:

void RemoveAll<T>(Func<T,bool> predicate,List<T> list)
{
    while(list.Any(predicate)) list.Remove(list.First(predicate));
}

+1 only to encourage you to leave your answer here for learning purposes. You're also right about it being off-topic, but I won't ding you for that because of there is significant value in leaving your examples here, again, strictly for learning purposes. I'm posting this response as an edit because posting it as a series of comments would be unruly.

Though your examples are short & compact, neither is elegant in terms of efficiency; the first is bad at O(n²), the second, absolutely abysmal at O(n³). Algorithmic efficiency of O(n²) is bad and should be avoided whenever possible, especially in general-purpose code; efficiency of O(n³) is horrible and should be avoided in all cases except when you know n will always be very small. Some might fling out their "premature optimization is the root of all evil" battle axes, but they do so naïvely because they do not truly understand the consequences of quadratic growth since they've never coded algorithms that have to process large datasets. As a result, their small-dataset-handling algorithms just run generally slower than they could, and they have no idea that they could run faster. The difference between an efficient algorithm and an inefficient algorithm is often subtle, but the performance difference can be dramatic. The key to understanding the performance of your algorithm is to understand the performance characteristics of the primitives you choose to use.

In your first example, list.Contains() and Remove() are both O(n), so a while() loop with one in the predicate & the other in the body is O(n²); well, technically O(m*n), but it approaches O(n²) as the number of elements being removed (m) approaches the length of the list (n).

Your second example is even worse: O(n³), because for every time you call Remove(), you also call First(predicate), which is also O(n). Think about it: Any(predicate) loops over the list looking for any element for which predicate() returns true. Once it finds the first such element, it returns true. In the body of the while() loop, you then call list.First(predicate) which loops over the list a second time looking for the same element that had already been found by list.Any(predicate). Once First() has found it, it returns that element which is passed to list.Remove(), which loops over the list a third time to yet once again find that same element that was previously found by Any() and First(), in order to finally remove it. Once removed, the whole process starts over at the beginning with a slightly shorter list, doing all the looping over and over and over again starting at the beginning every time until finally no more elements matching the predicate remain. So the performance of your second example is O(m*m*n), or O(n³) as m approaches n.

Your best bet for removing all items from a list that match some predicate is to use the generic list's own List<T>.RemoveAll(predicate) method, which is O(n) as long as your predicate is O(1). A for() loop technique that passes over the list only once, calling list.RemoveAt() for each element to be removed, may seem to be O(n) since it appears to pass over the loop only once. Such a solution is more efficient than your first example, but only by a constant factor, which in terms of algorithmic efficiency is negligible. Even a for() loop implementation is O(m*n) since each call to Remove() is O(n). Since the for() loop itself is O(n), and it calls Remove() m times, the for() loop's growth is O(n²) as m approaches n.

I would add that HTMLElement has a built-in .blur method as well.

Here's a demo using both .focus and .blur which work in similar ways.

const input = document.querySelector("#myInput");

<input id="myInput" value="Some Input">_x000D_
_x000D_
<button type="button" onclick="input.focus()">Focus</button>_x000D_
<button type="button" onclick="input.blur()">Lose focus</button>

For Kotlin users, I created a ImageStorageManager class which will handle save, get and delete actions for images easily:

class ImageStorageManager {
    companion object {
        fun saveToInternalStorage(context: Context, bitmapImage: Bitmap, imageFileName: String): String {
            context.openFileOutput(imageFileName, Context.MODE_PRIVATE).use { fos ->
                bitmapImage.compress(Bitmap.CompressFormat.PNG, 25, fos)
            }
            return context.filesDir.absolutePath
        }

        fun getImageFromInternalStorage(context: Context, imageFileName: String): Bitmap? {
            val directory = context.filesDir
            val file = File(directory, imageFileName)
            return BitmapFactory.decodeStream(FileInputStream(file))
        }

        fun deleteImageFromInternalStorage(context: Context, imageFileName: String): Boolean {
            val dir = context.filesDir
            val file = File(dir, imageFileName)
            return file.delete()
        }
    }
}

1. First Replace the MySQL dependency as given below

   <dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
       <version>5.1.44</version>
   </dependency>
   

2. An error showing "Authentication plugin 'caching_sha2_password'" will appear. Run this command:

   ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
   

Let's assume the stack which we will be working on is this :

6 , minvalue=2
2 , minvalue=2
5 , minvalue=3
3 , minvalue=3
9 , minvalue=7
7 , minvalue=7
8 , minvalue=8

In the above representation the stack is only built by left value's the right value's [minvalue] is written only for illustration purpose which will be stored in one variable.

The actual Problem is when the value which is the minimun value get's removed at that point how can we know what is the next minimum element without iterating over the stack.

Like for example in our stack when 6 get's popped we know that ,this is not the minimum element because the minimum element is 2 ,so we can safely remove this without updating our min value.

But when we pop 2 ,we can see that the minimum value is 2 right now and if this get's popped out then we need to update the minimum value to 3.

Point1:

Now if you observe carefully we need to generate minvalue=3 from this particular state [2 , minvalue=2]. or if you go depperin the stack we need to generate minvalue=7 from this particular state [3 , minvalue=3] or if you go more depper in the stack then we need to generate minvalue=8 from this particular state[7 , minvalue=7]

Did you notice something in common in all of the above 3 cases the value which we need to generate depends upon two variable which are both equal. Correct. Why is this happening because when we push some element smaller then the current minvalue, then we basically push that element in the stack and updated the same number in minvalue also.

Point2:

So we are basically storing duplicate of the same number once in stack and once in minvalue variable. We need to focus on avoiding this duplication and store something useful data in the stack or the minvalue to generate the previous minimum as shown in CASES above.

Let's focus on what should we store in stack when the value to store in push is less than the minmumvalue. Let's name this variable y , so now our stack will look something like this:

6 , minvalue=2
y1 , minvalue=2
5 , minvalue=3
y2 , minvalue=3
9 , minvalue=7
y3 , minvalue=7
8 , minvalue=8

I have renamed them as y1,y2,y3 to avoid confusion that all of them will have same value.

Point3:

Now Let's try to find some constraint's over y1,y2and y3. Do you remember when exactly we need to update the minvalue while doing pop() ,only when we have popped the element which is equal to the minvalue. If we pop something greater than the minvalue then we don't have to update minvalue. So to trigger the update of minvalue, y1,y2&y3 should be smaller than there corresponding minvalue .[We are avoding equality to avoid duplicate[Point2]] so the constrain is [ y < minValue ].

Now let's come back to populate y ,we need to generate some value and put y at the time of push ,remember. Let's take the value which is coming for push to be x which is less that the prevMinvalue,and the value which we will actually push in stack to be y. So one thing is obvious that the newMinValue=x , and y < newMinvalue.

Now we need to calulate y(remember y can be anynumber which is less than newMinValue(x) so we need to find some number which can fulfill our constraint) with the help of prevMinvalue and x(newMinvalue).

Let's do the math:
    x < prevMinvalue [Given]
    x - prevMinvalue < 0 
    x - prevMinValue + x < 0 + x [Add x on both side]
    2*x - prevMinValue < x      
this is the y which we were looking for less than x(newMinValue).
y = 2*x - prevMinValue. 'or' y = 2*newMinValue - prevMinValue 'or' y = 2*curMinValue - prevMinValue [taking curMinValue=newMinValue].

So at the time of pushing x if it is less than prevMinvalue then we push y[2*x-prevMinValue] and update newMinValue = x .

And at the time of pop if the stack contains something less than the minValue then that's our trigger to update the minVAlue. We have to calculate prevMinValue from the curMinValue and y. y = 2*curMinValue - prevMinValue [Proved] prevMinVAlue = 2*curMinvalue - y .

2*curMinValue - y is the number which we need to update now to the prevMinValue.

Code for the same logic is shared below with O(1) time and O(1) space complexity.

// getMinimum() in O(1) time and O(1) extra space.

Try double-clicking on the bottom right hand corner of the cell (ie on the box that you would otherwise drag).

Retrieve year, month, and day, and then put them together. Straight, simple, and accurate.

function formatDate(date) {_x000D_
    var year = date.getFullYear().toString();_x000D_
    var month = (date.getMonth() + 101).toString().substring(1);_x000D_
    var day = (date.getDate() + 100).toString().substring(1);_x000D_
    return year + "-" + month + "-" + day;_x000D_
}_x000D_
_x000D_
//Usage example:_x000D_
alert(formatDate(new Date()));

It's also useful for polyglot programs:

#!/usr/bin/env sh
':' //; exec "$(command -v node)" "$0" "$@"
~function(){ ... }

This is now both an executable shell-script and a JavaScript program: meaning ./filename.js, sh filename.js, and node filename.js all work.

(Definitely a little bit of a strange usage, but effective nonetheless.)

Some explication, as requested:

• Shell-scripts are evaluated line-by-line; and the exec command, when run, terminates the shell and replaces it's process with the resultant command. This means that to the shell, the program looks like this:

  #!/usr/bin/env sh
  ':' //; exec "$(command -v node)" "$0" "$@"
  

• As long as no parameter expansion or aliasing is occurring in the word, any word in a shell-script can be wrapped in quotes without changing its' meaning; this means that ':' is equivalent to : (we've only wrapped it in quotes here to achieve the JavaScript semantics described below)

• ... and as described above, the first command on the first line is a no-op (it translates to : //, or if you prefer to quote the words, ':' '//'. Notice that the // carries no special meaning here, as it does in JavaScript; it's just a meaningless word that's being thrown away.)

• Finally, the second command on the first line (after the semicolon), is the real meat of the program: it's the exec call which replaces the shell-script being invoked, with a Node.js process invoked to evaluate the rest of the script.

• Meanwhile, the first line, in JavaScript, parses as a string-literal (':'), and then a comment, which is deleted; thus, to JavaScript, the program looks like this:

  ':'
  ~function(){ ... }
  

  Since the string-literal is on a line by itself, it is a no-op statement, and is thus stripped from the program; that means that the entire line is removed, leaving only your program-code (in this example, the function(){ ... } body.)

You can also use this:

DF[paste0("stu",c(2,3,5,9)), ]

Another solution for dataframes which are not too large is (building on @thelatemail answer):

x <- data.frame(q=1,w=2,e=3)

> x
  q w e
1 1 2 3

colnames(x) <- c("A","w","B")

> x
  A w B
1 1 2 3

Alternatively, you can also use:

names(x) <- c("C","w","D")

> x
  C w D
1 1 2 3

Furthermore, you can also rename a subset of the columnnames:

names(x)[2:3] <- c("E","F")

> x
  C E F
1 1 2 3

The other way to see it in windows command line :

tasklist /fi "imagename eq nginx.exe"

INFO: No tasks are running which match the specified criteria.

if there is a running nginx you will see them

Adding margin to align images:

Since we wanted the image to be left-aligned, we added:

img {
  margin-right: auto;
}

Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.

Good Luck...

Java 7 introduced stricter verification and changed the class format a bit—to contain a stack map used to verify that code is correct. The exception you see means that some method doesn't have a valid stack map.

Java version or bytecode instrumentation could both be to blame. Usually this means that a library used by the application generates invalid bytecode that doesn't pass the stricter verification. So nothing else than reporting it as a bug to the library can be done by the developer.

As a workaround you can add -noverify to the JVM arguments in order to disable verification. In Java 7 it was also possible to use -XX:-UseSplitVerifier to use the less strict verification method, but that option was removed in Java 8.

I just came across overloading.py (function overloading for Python 3) for anybody who may be interested.

From the linked repository's README file:

overloading is a module that provides function dispatching based on the types and number of runtime arguments.

When an overloaded function is invoked, the dispatcher compares the supplied arguments to available function signatures and calls the implementation that provides the most accurate match.

Features

Function validation upon registration and detailed resolution rules guarantee a unique, well-defined outcome at runtime. Implements function resolution caching for great performance. Supports optional parameters (default values) in function signatures. Evaluates both positional and keyword arguments when resolving the best match. Supports fallback functions and execution of shared code. Supports argument polymorphism. Supports classes and inheritance, including classmethods and staticmethods.

Ensure that the permissions on your home directory and on the home directory of the user on the host you're connecting to are set to 700 ( owning user rwx only to prevent others seeing the .ssh subdirectory ).

Then ensure that the ~/.ssh directory is also 700 ( user rwx ) and that the authorized_keys is 600 ( user rw ) .

Private keys in your ~/.ssh directory should be 600 or 400 ( user rw or user r )

I resolved this kind of issue like this: I went into my XML layout file, cut the line of code that was generating the error. Then I saved the file, and pasted the code back in. The error was gone.

no, you can't do that, but you can use event handlers to change the title:

<img src="foo.jpg" onmouseover="this.title='it is now ' + new Date()" /> 

Don't provide the handler to execute.

Get the HttpResponse object, use the handler to get the body and get the status code from it directly

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
    final HttpGet httpGet = new HttpGet(GET_URL);

    try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
        StatusLine statusLine = response.getStatusLine();
        System.out.println(statusLine.getStatusCode() + " " + statusLine.getReasonPhrase());
        String responseBody = EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8);
        System.out.println("Response body: " + responseBody);
    }
}

For quick single calls, the fluent API is useful:

Response response = Request.Get(uri)
        .connectTimeout(MILLIS_ONE_SECOND)
        .socketTimeout(MILLIS_ONE_SECOND)
        .execute();
HttpResponse httpResponse = response.returnResponse();
StatusLine statusLine = httpResponse.getStatusLine();

For older versions of java or httpcomponents, the code might look different.

Additionally, DataContractSerializer will serialize items marked as [Serializable] and will also serialize unmarked types in .NET 3.5 SP1 and later, to allow support for serializing anonymous types.

So, it depends on how you've decorated your class as to how to keep a member from serializing:

• If you used [DataContract], then remove the [DataMember] for the property.
• If you used [Serializable], then add [NonSerialized] in front of the field for the property.
• If you haven't decorated your class, then you should add [IgnoreDataMember] to the property.

WITH  q AS
        (
        SELECT TOP 1 *
        FROM    mytable
        /* You may want to add ORDER BY here */
        )
DELETE
FROM    q

Note that

DELETE TOP (1)
FROM   mytable

will also work, but, as stated in the documentation:

The rows referenced in the TOP expression used with INSERT, UPDATE, or DELETE are not arranged in any order.

Therefore, it's better to use WITH and an ORDER BY clause, which will let you specify more exactly which row you consider to be the first.

If you just want to know the number, rather than get it in a query then you can use:

SHOW CREATE TABLE tablename;

You should see the auto_increment at the bottom

Per the specification, the JSON grammar's char production can take the following values:

• any-Unicode-character-except-"-or-\-or-control-character
• \"
• \\
• \/
• \b
• \f
• \n
• \r
• \t
• \u four-hex-digits

Newlines are "control characters", so no, you may not have a literal newline within your string. However, you may encode it using whatever combination of \n and \r you require.

The JSONLint tool confirms that your JSON is invalid.

And, if you want to write newlines inside your JSON syntax without actually including newlines in the data, then you're doubly out of luck. While JSON is intended to be human-friendly to a degree, it is still data and you're trying to apply arbitrary formatting to that data. That is absolutely not what JSON is about.

You can use a lambda with an input parameter, like so:

.Returns((string myval) => { return myval; });

Or slightly more readable:

.Returns<string>(x => x);

Can you place the #ulId in the document prior to the ajax load (with css display: none;), or wrap it in a containing div (with css display: none;), then just load the inner html during ajax page load, that way the scroll event will be linked to the div that is already there prior to the ajax?

Then you can use:

$('#ulId').on('scroll',function(){ console.log('Event Fired'); })

obviously replacing ulId with whatever the actual id of the scrollable div is.

Then set css display: block; on the #ulId (or containing div) upon load?

Assuming the points are (Ax,Ay) (Bx,By) and (Cx,Cy), you need to compute:

(Bx - Ax) * (Cy - Ay) - (By - Ay) * (Cx - Ax)

This will equal zero if the point C is on the line formed by points A and B, and will have a different sign depending on the side. Which side this is depends on the orientation of your (x,y) coordinates, but you can plug test values for A,B and C into this formula to determine whether negative values are to the left or to the right.

$.fn.textWidth = function(){
  var html_org = $(this).html();
  var html_calc = '<span>' + html_org + '</span>';
  $(this).html(html_calc);
  var width = $(this).find('span:first').width();
  $(this).html(html_org);
  return width;
};

Let's Say If you want to go from ViewController A --> B then

1. Make sure your ViewControllerA is embedded in Navigation Controller

2. In ViewControllerA's Button click you should have code like this.

@IBAction func goToViewController(_ sender: Any) {

    if let viewControllerB = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ViewControllerB") as? ViewControllerB {

        if let navigator = navigationController {
            navigator.pushViewController(viewControllerB, animated: true)
        }
    }
}

3. Please double check your storyboard name, and ViewControllerB's Identifier mentioned in storyboard for ViewControllerB's View

Look at StoryboardID = ViewControllerB

import glob

jpgFilenamesList = glob.glob('145592*.jpg')

See glob in python documenttion

use return to exit from a method.

 public void someMethod() {
        //... a bunch of code ...
        if (someCondition()) {
            return;
        }
        //... otherwise do the following...
    }

Here's another example

int price = quantity * 5;
        if (hasCream) {
            price=price + 1;
        }
        if (haschocolat) {
            price=price + 2;
        }
        return price;

When compiling memcached under Centos 5.x i got the same problem.

The solution is to upgrade gcc and g++ to version 4.4 at least.

Make sure your CC/CXX is set (exported) to right binaries before compiling.

Parse int

parseInt(canvas.css("margin-left")); 

returns 0 for 0px

If you use the fish shell its quite straight forward. fish is an interactive shell which comes with lots of goodies. You can install it using apt-get.

sudo apt-get install fish

you can then change the prompt setting using

> fish_config 
Web config started at 'http://localhost:8001/'. Hit enter to stop.
Created new window in existing browser session.

now go to http://localhost:8001/ open the prompt tab and choose the classic + git option

Now click on the use prompt button and you are set.

use below method to delete entire main directory which contains files and it's sub directory. After calling this method once again call delete() directory of your main directory.

// For to Delete the directory inside list of files and inner Directory
public static boolean deleteDir(File dir) {
    if (dir.isDirectory()) {
        String[] children = dir.list();
        for (int i=0; i<children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
    }

    // The directory is now empty so delete it
    return dir.delete();
}

Had a quick snoop around for this one, but this looks like it should work. I haven't tested it yet though.

    File f = new File("."); // current directory

    File[] files = f.listFiles();
    for (File file : files) {
        if (file.isDirectory()) {
            System.out.print("directory:");
        } else {
            System.out.print("     file:");
        }
        System.out.println(file.getCanonicalPath());
    }

The "Pythonic" way to check if a string is empty is:

import random
variable = random.choice(l)
if variable:
    # got a non-empty string
else:
    # got an empty string

In a similar situation like this where I had to write Test Case which is dependent on Environment Variable, I tried following:

1. I went for System Rules as suggested by Stefan Birkner. Its use was simple. But sooner than later, I found the behavior erratic. In one run, it works, in the very next run it fails. I investigated and found that System Rules work well with JUnit 4 or higher version. But in my cases, I was using some Jars which were dependent on JUnit 3. So I skipped System Rules. More on it you can find here @Rule annotation doesn't work while using TestSuite in JUnit.
2. Next I tried to create Environment Variable through Process Builder class provided by Java. Here through Java Code we can create an environment variable, but you need to know the process or program name which I did not. Also it creates environment variable for child process, not for the main process.

I wasted a day using the above two approaches, but of no avail. Then Maven came to my rescue. We can set Environment Variables or System Properties through Maven POM file which I think best way to do Unit Testing for Maven based project. Below is the entry I made in POM file.

    <build>
      <plugins>
       <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <systemPropertyVariables>
              <PropertyName1>PropertyValue1</PropertyName1>                                                          
              <PropertyName2>PropertyValue2</PropertyName2>
          </systemPropertyVariables>
          <environmentVariables>
            <EnvironmentVariable1>EnvironmentVariableValue1</EnvironmentVariable1>
            <EnvironmentVariable2>EnvironmentVariableValue2</EnvironmentVariable2>
          </environmentVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>

After this change, I ran Test Cases again and suddenly all worked as expected. For reader's information, I explored this approach in Maven 3.x, so I have no idea on Maven 2.x.
