I know this is an old question, but I also know that some people are just like me and are always looking for uptodate answers, since old answers can sometimes have deprecated information if not updated.

Its now January 2020, and I am using Django 2.2.6 and Python 3.7

Note: I use DJANGO REST FRAMEWORK, the code below for sending email was in a model viewset in my views.py

So after reading multiple nice answers, this is what I did.

from django.template.loader import render_to_string
from django.core.mail import EmailMultiAlternatives

def send_receipt_to_email(self, request):

    emailSubject = "Subject"
    emailOfSender = "[email protected]"
    emailOfRecipient = '[email protected]'

    context = ({"name": "Gilbert"}) #Note I used a normal tuple instead of  Context({"username": "Gilbert"}) because Context is deprecated. When I used Context, I got an error > TypeError: context must be a dict rather than Context

    text_content = render_to_string('receipt_email.txt', context, request=request)
    html_content = render_to_string('receipt_email.html', context, request=request)

    try:
        #I used EmailMultiAlternatives because I wanted to send both text and html
        emailMessage = EmailMultiAlternatives(subject=emailSubject, body=text_content, from_email=emailOfSender, to=[emailOfRecipient,], reply_to=[emailOfSender,])
        emailMessage.attach_alternative(html_content, "text/html")
        emailMessage.send(fail_silently=False)

    except SMTPException as e:
        print('There was an error sending an email: ', e) 
        error = {'message': ",".join(e.args) if len(e.args) > 0 else 'Unknown Error'}
        raise serializers.ValidationError(error)

Important! So how does render_to_string get receipt_email.txt and receipt_email.html? In my settings.py, I have TEMPLATES and below is how it looks

Pay attention to DIRS, there is this line os.path.join(BASE_DIR, 'templates', 'email_templates') .This line is what makes my templates accessible. In my project_dir, I have a folder called templates, and a sub_directory called email_templates like this project_dir->templates->email_templates. My templates receipt_email.txt and receipt_email.html are under the email_templates sub_directory.

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates'), os.path.join(BASE_DIR, 'templates', 'email_templates')],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

Let me just add that, my recept_email.txt looks like this;

Dear {{name}},
Here is the text version of the email from template

And, my receipt_email.html looks like this;

Dear {{name}},
<h1>Now here is the html version of the email from the template</h1>

In a comment on @paxdiablo's answer, you asked:

"So basically, is it better to use Double than Float?"

That is a complicated question. I will deal with it in two parts

Deciding between double versus float

On the one hand, a double occupies 8 bytes versus 4 bytes for a float. If you have many of them, this may be significant, though it may also have no impact. (Consider the case where the values are in fields or local variables on a 64bit machine, and the JVM aligns them on 64 bit boundaries.) Additionally, floating point arithmetic with double values is typically slower than with float values ... though once again this is hardware dependent.

On the other hand, a double can represent larger (and smaller) numbers than a float and can represent them with more than twice the precision. For the details, refer to Wikipedia.

The tricky question is knowing whether you actually need the extra range and precision of a double. In some cases it is obvious that you need it. In others it is not so obvious. For instance if you are doing calculations such as inverting a matrix or calculating a standard deviation, the extra precision may be critical. On the other hand, in some cases not even double is going to give you enough precision. (And beware of the trap of expecting float and double to give you an exact representation. They won't and they can't!)

There is a branch of mathematics called Numerical Analysis that deals with the effects of rounding error, etc in practical numerical calculations. It used to be a standard part of computer science courses ... back in the 1970's.

Deciding between Double versus Float

For the Double versus Float case, the issues of precision and range are the same as for double versus float, but the relative performance measures will be slightly different.

• A Double (on a 32 bit machine) typically takes 16 bytes + 4 bytes for the reference, compared with 12 + 4 bytes for a Float. Compare this to 8 bytes versus 4 bytes for the double versus float case. So the ratio is 5 to 4 versus 2 to 1.

• Arithmetic involving Double and Float typically involves dereferencing the pointer and creating a new object to hold the result (depending on the circumstances). These extra overheads also affect the ratios in favor of the Double case.

Correctness

Having said all that, the most important thing is correctness, and this typically means getting the most accurate answer. And even if accuracy is not critical, it is usually not wrong to be "too accurate". So, the simple "rule of thumb" is to use double in preference to float, UNLESS there is an overriding performance requirement, AND you have solid evidence that using float will make a difference with respect to that requirement.

Yes, the new limit is approximately 1 million rows.

You can easily print a void printer

int p=15;
void *q;
q=&p;
printf("%d",*((int*)q));

Hold down the Alt key and drag the pictures to snap to the upper left corner of the cell.

Format the picture and in the Properties tab select "Move but don't size with cells"

Now you can sort the data table by any column and the pictures will stay with the respective data.

This post at SuperUser has a bit more background and screenshots: https://superuser.com/questions/712622/put-an-equation-object-in-an-excel-cell/712627#712627

If you learn Python first and then Java. I think it plays the same role as __str__() method in Python, it is a magic method like __dict__() and __init__() but to refer to a string representing the the object.

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

Note: The placement of cross_origin should be right and dependencies are installed. On the client side, ensure to specify kind of data server is consuming. For example application/json or text/html

For me the code written below did magic

from flask import Flask,request,jsonify
from flask_cors import CORS,cross_origin
app=Flask(__name__)
CORS(app, support_credentials=True)
@app.route('/api/test', methods=['POST', 'GET','OPTIONS'])
@cross_origin(supports_credentials=True)
def index():
    if(request.method=='POST'):
     some_json=request.get_json()
     return jsonify({"key":some_json})
    else:
        return jsonify({"GET":"GET"})


if __name__=="__main__":
    app.run(host='0.0.0.0', port=5000)

The main reason is probably that a C++ string is a struct that includes a current-length value, not just the address of a sequence of chars terminated by a 0 byte. Printf and its relatives expect to find such a sequence, not a struct, and therefore get confused by C++ strings.

Speaking for myself, I believe that printf has a place that can't easily be filled by C++ syntactic features, just as table structures in html have a place that can't easily be filled by divs. As Dykstra wrote later about the goto, he didn't intend to start a religion and was really only arguing against using it as a kludge to make up for poorly-designed code.

It would be quite nice if the GNU project would add the printf family to their g++ extensions.

This is how the kids are doing it today:

DECLARE @test DECIMAL(18,6) = 123.456789
SELECT FORMAT(@test, '##.##')

123.46

I changed ValidateExternalMetadata=False for each transformation task. It worked for me.

Quick Cut and Overwrite portion of a line:

A very common task when you are editing a line is to cut from the current cursor location till a certain place and overwrite the new content.

You can use the following commands:

ct<identifier> for forward cutting.

cT<identifier> for backward cutting.

Where is the character in the line till which you want to cut.

Example: Lets say this the line you want to edit and your cursor is at I.

Hi There. I am a Coder and I code in : Python and R.

You want to cut till : and overwrite with I am a programmer, you type: ct: then type I am a programmer. This will result in: Hi There. I am a programmer: Python and R.

Quick Delete portion of a line:

Just like above the following commands delete the content from the current cursor location till the 'identifier'

dt<identifier> for forward delete

dT<identifier> for backward delete

Hope this is useful to you too.

I have an Xml File books.xml

<ParameterDBConfig>
    <ID Definition="1" />
</ParameterDBConfig>

Program:

XmlDocument doc = new XmlDocument();
doc.Load("D:/siva/books.xml");
XmlNodeList elemList = doc.GetElementsByTagName("ID");     
for (int i = 0; i < elemList.Count; i++)     
{
    string attrVal = elemList[i].Attributes["Definition"].Value;
}

Now, attrVal has the value of ID.

With quotes around the date:

mysql> CALL insertEvent('2012.01.01 12:12:12');

You can also evaluate a command using the --eval flag, if it is just a single command.

mongo --eval "printjson(db.serverStatus())"

Please note: if you are using Mongo operators, starting with a $ sign, you'll want to surround the eval argument in single quotes to keep the shell from evaluating the operator as an environment variable:

mongo --eval 'db.mycollection.update({"name":"foo"},{$set:{"this":"that"}});' myDbName

Otherwise you may see something like this:

mongo --eval "db.test.update({\"name\":\"foo\"},{$set:{\"this\":\"that\"}});"
> E QUERY    SyntaxError: Unexpected token :

A simple case that generates this error message:

In [8]: [1,2,3,4,5][np.array([1])]
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

----> 1 [1,2,3,4,5][np.array([1])]

TypeError: only integer scalar arrays can be converted to a scalar index

Some variations that work:

In [9]: [1,2,3,4,5][np.array(1)]     # this is a 0d array index
Out[9]: 2
In [10]: [1,2,3,4,5][np.array([1]).item()]    
Out[10]: 2
In [11]: np.array([1,2,3,4,5])[np.array([1])]
Out[11]: array([2])

Basic python list indexing is more restrictive than numpy's:

In [12]: [1,2,3,4,5][[1]]
....
TypeError: list indices must be integers or slices, not list

edit

Looking again at

indices = np.random.choice(range(len(X_train)), replace=False, size=50000, p=train_probs)

indices is a 1d array of integers - but it certainly isn't scalar. It's an array of 50000 integers. List's cannot be indexed with multiple indices at once, regardless of whether they are in a list or array.

The Return View(model) returns you error because you don't fill the model with the values in your post method and the model data for the dropdown is empty. Please provide the Get method to explain further how to manage displaying the error. In order to the error to be shown you should use this:

[HttpPost]
public ActionResult form_edit(FormModels model)
{          
   if(ModelState.IsValid())
   {
      --- operations 
      return Redirect("OtherAction", "SomeController");
   }

   // here you can use a little trick
   //fill the model property that holds the information for the dropdown with the data 

   // you haven't provided the get method but it should look something like this
   model.Countries = ... some data goes here;
   model.dd_value = ... some other data;
   model.dd_text = ... other data;

   ModelState.AddModelError("", "adfdghdghgdhgdhdgda");
   return View(model);
}

and then in the view just use :

@model mvc_cs.Models.FormModels
@using ctrlr = mvc_cs.Controllers.FormController


@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{

    <table>
    <tr>
    <td>       
    @Html.ValidationSummary(true)             
    </td>
    </tr>
<tr>
    <th>
        @Html.DisplayNameFor(model => model.content_name)
        @Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")

    </th>
</tr>
</table>

<table>
<tr>
    <td>
        <input  type="submit" value="Submit" />
    </td>
</tr>
</table>
}

This should work okay.

If you just use RedirectToAction it will redirect you to the get method --> you will have no error but the view will be just reloaded and no error would be shown.

other way around is that you can pass the error not by ModelState.AddError, but with ViewData["error"] like this:

[HttpPost]
public ActionResult form_edit(FormModels model)
{          
   TempData["error"] = "someErrorMessage";
   return RedirectToAction("form_Post", "Form");
}

[HttpGet]
public ActionResult form_edit()
{
    do stuff here ----
    ViewData["error"] = TempData["error"];
    return View();
}

@model mvc_cs.Models.FormModels
@using ctrlr = mvc_cs.Controllers.FormController


@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{

    <table>
    <tr>
    <td>       
    <div>@ViewData["error"]</div>             
    </td>
    </tr>
<tr>
    <th>
        @Html.DisplayNameFor(model => model.content_name)
        @Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")

    </th>
</tr>
</table>

<table>
<tr>
    <td>
        <input  type="submit" value="Submit" />
    </td>
</tr>
</table>
}

i was having same problem with this error. It turn out my Kenel.php is having a wrong syntax when i try to comply with wrong php8 syntax

The line should be

protected $commands = [
    //
];

instead of

protected array $commands = [
        //
];

I personal recommended that the sql below because when i try use date function in the condition clause, its slow down my query speed very much.

anyway feel free to try this.

select CONCAT(DATEPART(YYYY,@mydate),'-',DATEPART(MM,@mydate),'-01')

If you've got many database it import and the dumps is big (I often work with multigigabyte Gzipped dumps).

There here a way to do it inside mysql.

$ mkdir databases
$ cd databases
$ scp user@orgin:*.sql.gz .  # Here you would just use putty to copy into this dir.
$ mkfifo src
$ mysql -u root -p
Enter password:

The only advantage this has over

zcat db1.sql.gz | mysql -u root -p 

is that you can easily do multiple without enter the password lots of times.

My contribution in ES6 terms. In general it finds the intersection of an array with indefinite number of arrays provided as arguments.

Just write

declare var $:any;

after all import sections, you can use jQuery and include the jQuery library in your index.html page

<script src="https://code.jquery.com/jquery-3.3.1.js"></script>

it worked for me

If you don't want TypeScript compilation, disable it in your .csproj file, according to this post.

Just add the following line to your .csproj file:

<TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>

Dim SourcePath As String = "c:\SomeFolder\SomeFileYouWantToCopy.txt" 'This is just an example string and could be anything, it maps to fileToCopy in your code.
Dim SaveDirectory As string = "c:\DestinationFolder"

Dim Filename As String = System.IO.Path.GetFileName(SourcePath) 'get the filename of the original file without the directory on it
Dim SavePath As String = System.IO.Path.Combine(SaveDirectory, Filename) 'combines the saveDirectory and the filename to get a fully qualified path.

If System.IO.File.Exists(SavePath) Then
   'The file exists
Else
    'the file doesn't exist
End If

You could get the array of elements by name the old fashioned way and pass that array to jQuery.

function toggleByName() {_x000D_
  var arrChkBox = document.getElementsByName("chName");_x000D_
  $(arrChkBox).toggle();_x000D_
}

    <input type="button" onclick="toggleByName();" value="toggle"/>_x000D_
  </body>_x000D_
</html>

note: the only time you would have a reason to use the "name" attribute should be for checkbox or radio inputs.

Or you could just add another class to the elements for selection.(This is what I would do)

function toggleByClass(bolShow) {_x000D_
  if (bolShow) {_x000D_
    $(".rowToToggle").show();_x000D_

SMS Push uses SMS as a carrier, WAP uses download via WAP.

I was able unable to locate the svn.simple file, but was able to change credentials using the following three steps:

Checkout project from SVN

Select the repository you need to change the credentials on (note: you will not perform an checkout, but this will bring you to the screen to enter a username/password combination).

Finally, enter the new username and password credentials:

It's a bit confusing, because you begin the process of initializing a new project, but you're only resetting the repository credentials.

So I got this error when trying to display the createdAt property which is a Date object. If you concatenate .toString() on the end like this, it will do the conversion and eliminate the error. Just posting this as a possible answer in case anyone else ran into the same problem:

{this.props.task.createdAt.toString()}

Solution Using jQuery

 <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>

 <style>
    #form label{float:left; width:140px;}
    #error_msg{color:red; font-weight:bold;}
 </style>

 <script>
    $(document).ready(function(){
        var $submitBtn = $("#form input[type='submit']");
        var $passwordBox = $("#password");
        var $confirmBox = $("#confirm_password");
        var $errorMsg =  $('<span id="error_msg">Passwords do not match.</span>');

        // This is incase the user hits refresh - some browsers will maintain the disabled state of the button.
        $submitBtn.removeAttr("disabled");

        function checkMatchingPasswords(){
            if($confirmBox.val() != "" && $passwordBox.val != ""){
                if( $confirmBox.val() != $passwordBox.val() ){
                    $submitBtn.attr("disabled", "disabled");
                    $errorMsg.insertAfter($confirmBox);
                }
            }
        }

        function resetPasswordError(){
            $submitBtn.removeAttr("disabled");
            var $errorCont = $("#error_msg");
            if($errorCont.length > 0){
                $errorCont.remove();
            }  
        }


        $("#confirm_password, #password")
             .on("keydown", function(e){
                /* only check when the tab or enter keys are pressed
                 * to prevent the method from being called needlessly  */
                if(e.keyCode == 13 || e.keyCode == 9) {
                    checkMatchingPasswords();
                }
             })
             .on("blur", function(){                    
                // also check when the element looses focus (clicks somewhere else)
                checkMatchingPasswords();
            })
            .on("focus", function(){
                // reset the error message when they go to make a change
                resetPasswordError();
            })

    });
  </script>

And update your form accordingly:

<form id="form" name="form" method="post" action="registration.php"> 
    <label for="username">Username : </label>
    <input name="username" id="username" type="text" /></label><br/>

    <label for="password">Password :</label> 
    <input name="password" id="password" type="password" /><br/>

    <label for="confirm_password">Confirm Password:</label>
    <input type="password" name="confirm_password" id="confirm_password" /><br/>

    <input type="submit" name="submit"  value="registration"  />
</form>

This will do precisely what you asked for:

• validate that the password and confirm fields are equal without clicking the register button
• If password and confirm password field will not match it will place an error message at the side of confirm password field and disable registration button

It is advisable not to use a keyup event listener for every keypress because really you only need to evaluate it when the user is done entering information. If someone types quickly on a slow machine, they may perceive lag as each keystroke will kick off the function.

Also, in your form you are using labels wrong. The label element has a "for" attribute which should correspond with the id of the form element. This is so that when visually impaired people use a screen reader to call out the form field, it will know text belongs to which field.

2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

Agreed, code readability is very important for others, but more importantly yourself. Imagine how difficult it would be to understand the first example in comparison to the second.

If code takes more than a few seconds to read (understand), perhaps there is a better way to write it. In this case, the second way.

internal members are accessible within the assembly (only accessible in the same project)

private members are accessible within the same class

Example for Beginners

There are 2 projects in a solution (Project1, Project2) and Project1 has a reference to Project2.

• Public method written in Project2 will be accessible in Project2 and the Project1
• Internal method written in Project2 will be accessible in Project2 only but not in Project1
• private method written in class1 of Project2 will only be accessible to the same class. It will neither be accessible in other classes of Project 2 not in Project 1.

Use the following command before the execution of any pip command

hash -d pip

It will work

One thing that hasn't been mentioned is that a SOAP envelope can contain headers as well as body parts. This lets you use the full expressiveness of XML to send and receive out of band information. REST, as far as I know, limits you to HTTP Headers and result codes.

(otoh, can you use cookies with a REST service to send "header"-type out of band data?)

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

Bravo JSP Editor (Can't comment on how good it is, i haven't tried it) http://marketplace.eclipse.org/content/bravo-jsp-editor

For Windows Only

1 - You need to have Tesseract OCR installed on your computer.

get it from here. https://github.com/UB-Mannheim/tesseract/wiki

Download the suitable version.

2 - Add Tesseract path to your System Environment. i.e. Edit system variables.

3 - Run pip install pytesseract and pip install tesseract

4 - Add this line to your python script every time

pytesseract.pytesseract.tesseract_cmd = 'C:/OCR/Tesseract-OCR/tesseract.exe'  # your path may be different

5 - Run the code.

For regular Windows users who are not skilled with computers, it is practically not possible to install and use extensions from outside the Chrome Web Store.

Users of other operating systems (Linux, Mac, Chrome OS) can easily install unpacked extensions (in developer mode).
Windows users can also load an unpacked extension, but they will always see an information bubble with "Disable developer mode extensions" when they start Chrome or open a new incognito window, which is really annoying. The only way for Windows users to use unpacked extensions without such dialogs is to switch to Chrome on the developer channel, by installing https://www.google.com/chrome/browser/index.html?extra=devchannel#eula.

Extensions can be loaded in unpacked mode by following the following steps:

1. Visit chrome://extensions (via omnibox or menu -> Tools -> Extensions).
2. Enable Developer mode by ticking the checkbox in the upper-right corner.
3. Click on the "Load unpacked extension..." button.
4. Select the directory containing your unpacked extension.

If you have a crx file, then it needs to be extracted first. CRX files are zip files with a different header. Any capable zip program should be able to open it. If you don't have such a program, I recommend 7-zip.

These steps will work for almost every extension, except extensions that rely on their extension ID. If you use the previous method, you will get an extension with a random extension ID. If it is important to preserve the extension ID, then you need to know the public key of your CRX file and insert this in your manifest.json. I have previously given a detailed explanation on how to get and use this key at https://stackoverflow.com/a/21500707.

Example in C:

// function
int square( int n ) {
   return n * n;
}

// procedure
void display( int n ) {
   printf( "The value is %d", n );
}

Although you should note that the C Standard doesn't talk about procedures, only functions.

There is an issue on Chromium open since 2011, that if you are explicitly setting the domain as 'localhost', you should set it as false or undefined.

You have assing button to your imgButton variable:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    imgButton = (Button) findViewById(R.id.imgButton);
    imgButton.setOnClickListener(imgButtonHandler);
}

I use Hibernate Validator via @Valid for all input objects (binding and @RequestBody json, see https://dzone.com/articles/spring-31-valid-requestbody). So @org.hibernate.validator.constraints.SafeHtml is a good solution for me.

Hibernate SafeHtmlValidator depends on org.jsoup, so it's needed to add one more project dependencies:

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.10.1</version>
</dependency>

For bean User with field

@NotEmpty
@SafeHtml
protected String name;

for update attempt with value <script>alert(123)</script> in controller

@PutMapping(value = "/{id}", consumes = MediaType.APPLICATION_JSON_VALUE)
public void update(@Valid @RequestBody User user, @PathVariable("id") int id) 

or

@PostMapping
public void createOrUpdate(@Valid User user) {

is thrown BindException for binding and MethodArgumentNotValidException for @RequestBody with default message:

name may have unsafe html content

Validator works as well for binding, as before persisting. Apps could be tested at http://topjava.herokuapp.com/

UPDATE: see also comment from @GuyT

CVE-2019-10219 and status of @SafeHtml

We have been made aware of a CVE-2019-10219 related to the @SafeHtml constraint and it was fixed in both 6.0.18.Final and 6.1.0.Final....

However, we came to the conclusion that the @SafeHtml constraint was fragile, highly security-sensitive and depending on an external library that wasn’t designed for this purpose. Having it included in core Hibernate Validator was not a very good idea. That’s why we deprecated it and marked it for removal.There is no magic plan here so our users will have to maintain this constraint themselves

Resume for myself: it is safe and could be used, until solution better be found.

This is very simple in LinQ... You can use the select statement to get an Enumerable of properties of the objects.

var mySkus = myLines.Select(x => x.Sku);

Or if you want it as an Array just do...

var mySkus = myLines.Select(x => x.Sku).ToArray();

I would suggest to use ExpectedConditions and alertIsPresent(). ExpectedConditions is a wrapper class that implements useful conditions defined in ExpectedCondition interface.

public boolean isAlertPresent(){
    boolean foundAlert = false;
    WebDriverWait wait = new WebDriverWait(driver, 0 /*timeout in seconds*/);
    try {
        wait.until(ExpectedConditions.alertIsPresent());
        foundAlert = true;
    } catch (TimeoutException eTO) {
        foundAlert = false;
    }
    return foundAlert;
}

Note: this is based on the answer by nilesh, but adapted to catch the TimeoutException which is thrown by the wait.until() method.

for a pure shell solution without calling external program:

NL=$'\n'    # define a variable to reference 'newline'

testVar=${testVar%$NL}    # removes trailing 'NL' from string

Have you tried using @JsonProperty?

@Entity
public class City {
   @id
   Long id;
   String name;

   @JsonProperty("label")
   public String getName() { return name; }

   public void setName(String name){ this.name = name; }

   @JsonProperty("value")
   public Long getId() { return id; }

   public void setId(Long id){ this.id = id; }
}

If you are including the apache commons lang jar in your project than the easiest solution would be to do:

WordUtils.capitalize(Name)

takes care of all the dirty work for you. See the javadoc here

Alternatively, you also have a capitalizeFully(String) method which also lower cases the rest of the characters.

It works.

1. Make a jar file from your applet class and META-INF/MANIFEST.MF file.
2. Sign your jar file with your certificate.
3. Configure your local site permissions as > file:///C:/ or http: //localhost:8080
4. Then run your html document on Intenet Explorer on Windows.(Not Google Chrome !)

No, you need to wrap your TextBlock in a Border. Example:

<Border BorderThickness="1" BorderBrush="Black">
    <TextBlock ... />
</Border>

Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:

<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Black" />
</Style>

<Border Style="{StaticResource notCalledBorder}">
    <TextBlock ... />
</Border>

You could just clone the first row that has the inputs, then get the nested inputs and update their ID to add the row number (and do the same with the first cell).

function deleteRow(row)
{
    var i=row.parentNode.parentNode.rowIndex;
    document.getElementById('POITable').deleteRow(i);
}


function insRow()
{
    var x=document.getElementById('POITable');
       // deep clone the targeted row
    var new_row = x.rows[1].cloneNode(true);
       // get the total number of rows
    var len = x.rows.length;
       // set the innerHTML of the first row 
    new_row.cells[0].innerHTML = len;

       // grab the input from the first cell and update its ID and value
    var inp1 = new_row.cells[1].getElementsByTagName('input')[0];
    inp1.id += len;
    inp1.value = '';

       // grab the input from the first cell and update its ID and value
    var inp2 = new_row.cells[2].getElementsByTagName('input')[0];
    inp2.id += len;
    inp2.value = '';

       // append the new row to the table
    x.appendChild( new_row );
}

Yes, here you can use LIMIT.

You can try it by the below query:

SELECT * FROM employee_list SORT BY salary DESC LIMIT 2

Alter TABLE 'TARGET' add 'ShouldAddColumn' Integer Not Null default "0"

I just type brew -v in terminal if you have it it will respond with the version number installed.

// Add some tenants to context so we have something for the procedure to return! AddTenentsToContext(Context);

    // ACT
    // Get the results by calling the stored procedure from the context extention method 
    var results = Context.ExecuteStoredProcedure(procedure);

    // ASSERT
    Assert.AreEqual(expectedCount, results.Count);
}

As an addition to the main answers, which are good, comprehensive and accurate, I would like to comment about the article you reference - the one that says "throwing exceptions in destructors is not so bad".

The article takes the line "what are the alternatives to throwing exceptions", and lists some problems with each of the alternatives. Having done so it concludes that because we can't find a problem-free alternative we should keep throwing exceptions.

The trouble is is that none of the problems it lists with the alternatives are anywhere near as bad as the exception behaviour, which, let's remember, is "undefined behaviour of your program". Some of the author's objections include "aesthetically ugly" and "encourage bad style". Now which would you rather have? A program with bad style, or one which exhibited undefined behaviour?

INSERT INTO TABLE_NAME 
            (DATA1, 
             DATA2) 
VALUES      (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2), 
            (VAL1, 
             VAL2); 

Ran into this just now in a Unit Test project after adding MsTest V2 through Nuget. Renaming app.config (so effectively removing it) did the trick for me.

Having read through all the above posts, I'm still not sure why, sorry!

You can change source code, bootstrap-datepicker.js. Add this.hide(); like ne

  if (this.viewMode !== 0) {
    this.date = new Date(this.viewDate);
    this.element.trigger({
        type: 'changeDate',
        date: this.date,
        viewMode: DPGlobal.modes[this.viewMode].clsName
    });
    this.hide();//here
 }

This is a generic solution for your problem and others related.

1. Create auxiliar class UIHelper and put on the following methods:

    /**This method returns top view controller in application  */
    class func topViewController() -> UIViewController?
    {
        let helper = UIHelper()
        return helper.topViewControllerWithRootViewController(rootViewController: UIApplication.shared.keyWindow?.rootViewController)
    }

    /**This is a recursive method to select the top View Controller in a app, either with TabBarController or not */
    private func topViewControllerWithRootViewController(rootViewController:UIViewController?) -> UIViewController?
    {
        if(rootViewController != nil)
        {
            // UITabBarController
            if let tabBarController = rootViewController as? UITabBarController,
                let selectedViewController = tabBarController.selectedViewController {
                return self.topViewControllerWithRootViewController(rootViewController: selectedViewController)
            }

            // UINavigationController
            if let navigationController = rootViewController as? UINavigationController ,let visibleViewController = navigationController.visibleViewController {
                return self.topViewControllerWithRootViewController(rootViewController: visibleViewController)
            }

            if ((rootViewController!.presentedViewController) != nil) {
                let presentedViewController = rootViewController!.presentedViewController;
                return self.topViewControllerWithRootViewController(rootViewController: presentedViewController!);
            }else
            {
                return rootViewController
            }
        }

        return nil
    }

2. Create a Protocol with your desire behavior, for your specific case will be portrait.

protocol orientationIsOnlyPortrait {}

Nota: If you want, add it in the top of UIHelper Class.

3. Extend your View Controller

In your case:

class Any_ViewController: UIViewController,orientationIsOnlyPortrait {

   ....

}

4. In app delegate class add this method:

 func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        let presentedViewController = UIHelper.topViewController()
        if presentedViewController is orientationIsOnlyPortrait {
            return .portrait
        }
        return .all
    }

Final Notes:

• If you that more class are in portrait mode, just extend that protocol.
• If you want others behaviors from view controllers, create other protocols and follow the same structure.
• This example solves the problem with orientations changes after push view controllers

Using this HTML:

<div id="myElement" style="position: absolute">This stays at the top</div>

This is the javascript you want to use. It attaches an event to the window's scroll and moves the element down as far as you've scrolled.

$(window).scroll(function() {
    $('#myElement').css('top', $(this).scrollTop() + "px");
});

As pointed out in the comments below, it's not recommended to attach events to the scroll event - as the user scrolls, it fires A LOT, and can cause performance issues. Consider using it with Ben Alman's debounce/throttle plugin to reduce overhead.

EditText.setOnKeyListener(new OnKeyListener() {
            public boolean onKey(View view, int keyCode, KeyEvent event) {
                if (keyCode == KeyEvent.KEYCODE_ENTER) {
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(URLText.getWindowToken(), 0); 
                    EditText.setFocusable(false);
                    EditText.setFocusableInTouchMode(true);
                    return true;
                } else {
                    return false;
                }
            }
        });

According to the FAQ:

Some have asked for a compiler option to turn those checks off or at least reduce them to warnings. Such an option has not been added, though, because compiler options should not affect the semantics of the language and because the Go compiler does not report warnings, only errors that prevent compilation.

There are two reasons for having no warnings. First, if it's worth complaining about, it's worth fixing in the code. (And if it's not worth fixing, it's not worth mentioning.) Second, having the compiler generate warnings encourages the implementation to warn about weak cases that can make compilation noisy, masking real errors that should be fixed.

I don't necessarily agree with this for various reasons not worth going into. It is what it is, and it's not likely to change in the near future.

For packages, there's the goimports tool which automatically adds missing packages and removes unused ones. For example:

# Install it
$ go get golang.org/x/tools/cmd/goimports

# -w to write the source file instead of stdout
$ goimports -w my_file.go

You should be able to run this from any half-way decent editor - for example for Vim:

:!goimports -w %

The goimports page lists some commands for other editors, and you typically set it to be run automatically when you save the buffer to disk.

Note that goimports will also run gofmt.

As was already mentioned, for variables the easiest way is to (temporarily) assign them to _ :

// No errors
tasty := "ice cream"
horrible := "marmite"

// Commented out for debugging
//eat(tasty, horrible)

_, _ = tasty, horrible

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Kudos to this answer for showing me the way.

The same error will also appear if you use Glide, images won't show. To overcome it see Glide - javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found and How to set OkHttpClient for glide.

@GlideModule
class MyAppGlideModule : AppGlideModule() {

    val okHttpClient = Api.getOkHttpBuilder().build() // Api is the class written above.
    // It is better to create okHttpClient here and not use Api.okHttpClient,
    // because their settings may differ. For instance, it can use its own
    // `addInterceptor` and `addNetworkInterceptor` that can affect on a read JSON.


    override fun registerComponents(context: Context, glide: Glide, registry: Registry) {
        registry.replace(GlideUrl::class.java, InputStream::class.java,
            OkHttpUrlLoader.Factory(okHttpClient))
    }
}

build.gradle:

Have a look here -- to query a sub-element of an element:

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

<!DOCTYPE html>

// stores the device context of the canvas we use to draw the outlines

// takes a string that contains coords eg - "227,307,261,309, 339,354, 328,371, 240,331"
// draws a line from each co-ord pair to the next - assumes starting point needs to be repeated as ending point.
function drawPoly(coOrdStr)
{
    var mCoords = coOrdStr.split(',');
    var i, n;
    n = mCoords.length;

    hdc.beginPath();
    hdc.moveTo(mCoords[0], mCoords[1]);
    for (i=2; i<n; i+=2)
    {
        hdc.lineTo(mCoords[i], mCoords[i+1]);
    }
    hdc.lineTo(mCoords[0], mCoords[1]);
    hdc.stroke();
}

{
    var mCoords = coOrdStr.split(',');
    var top, left, bot, right;

The simplest way to do this is with a list comprehension:

[s + mystring for s in mylist]

Notice that I avoided using builtin names like list because that shadows or hides the builtin names, which is very much not good.

Also, if you do not actually need a list, but just need an iterator, a generator expression can be more efficient (although it does not likely matter on short lists):

(s + mystring for s in mylist)

These are very powerful, flexible, and concise. Every good python programmer should learn to wield them.

I think that mergetool.meld.path should point directly to the meld executable. Thus, the command you want is:

git config --global mergetool.meld.path c:/Progra~2/meld/bin/meld

With the release of RecyclerView library, now you can align a list of images bind with text easily. You can use LinearLayoutManager to specify the direction in which you would like to orient your list, either vertical or horizontal as shown below.

You can download a full working demo from this post

To set a custom height locked to somewhere:

body, html {_x000D_
  height: 100%;_x000D_
}_x000D_
#outerbox {_x000D_
  width: 100%;_x000D_
  position: absolute; /* to place it somewhere on the screen */_x000D_
  top: 130px;         /* free space at top */_x000D_
  bottom: 0;          /* makes it lock to the bottom */_x000D_
}_x000D_
#innerbox {_x000D_
  width: 100%;_x000D_
  position: absolute;    _x000D_
  min-height: 100% !important; /* browser fill */_x000D_
  height: auto;                /*content fill */_x000D_
}

<div id="outerbox">_x000D_
  <div id="innerbox"></div>_x000D_
</div>

I just did the same. I did it in helper controller, my code is:

def get_controller_name
  controller_name    
end


def get_action_name
  action_name   
end

These methods will return current contoller and action name. Hope it helps

I was trying on a release build via adb install -r -d <app-release>.apk

Make sure you're running the debug build, then the menu will work via the shortcut or CLI.

pandas.DataFrame.append

DataFrame.append(self, other, ignore_index=False, verify_integrity=False, sort=False) ? 'DataFrame'

df = pd.DataFrame([[1, 2], [3, 4]], columns=list('AB'))
df2 = pd.DataFrame([[5, 6], [7, 8]], columns=list('AB'))
df.append(df2)

With ignore_index set to True:

df.append(df2, ignore_index=True)

Piping something into an expression involving an assignment doesn't behave like that.

Instead, try:

test=$(echo "hello world"); echo test=$test

I strongly suggest to use httrack.

ex: httrack -v -w http://example.com/

It will do a mirror with 8 simultaneous connections as default. Httrack has a tons of options where to play. Have a look.

URI (Uniform Resource Identifier) according to Wikipedia:

a string of characters used to identify a resource.

URL (Uniform Resource Locator) is a URI that implies an interaction mechanism with resource. for example https://www.google.com specifies the use of HTTP as the interaction mechanism. Not all URIs need to convey interaction-specific information.

URN (Uniform Resource Name) is a specific form of URI that has urn as it's scheme. For more information about the general form of a URI refer to https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax

IRI (International Resource Identifier) is a revision to the definition of URI that allows us to use international characters in URIs.

You can try ng-file-upload angularjs plugin (instead of ng-upload).

It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.

html

<!-- Note: MUST BE PLACED BEFORE angular.js-->
<script src="ng-file-upload-shim.min.js"></script> 
<script src="angular.min.js"></script>
<script src="ng-file-upload.min.js"></script> 

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var file = $files[i];
      $scope.upload = $upload.upload({
        url: 'server/upload/url', //upload.php script, node.js route, or servlet url
        data: {myObj: $scope.myModelObj},
        file: file,
      }).progress(function(evt) {
        console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
      }).then(function(response) {
        var data = response.data;
        // file is uploaded successfully
        console.log(data);
      });
    }
  };
}];

With this chunk of code, you will get something like this

extension UIButton {
    func alignTextUnderImage() {
        guard let imageView = imageView else {
                return
        }
        self.contentVerticalAlignment = .Top
        self.contentHorizontalAlignment = .Center
        let imageLeftOffset = (CGRectGetWidth(self.bounds) - CGRectGetWidth(imageView.bounds)) / 2//put image in center
        let titleTopOffset = CGRectGetHeight(imageView.bounds) + 5
        self.imageEdgeInsets = UIEdgeInsetsMake(0, imageLeftOffset, 0, 0)
        self.titleEdgeInsets = UIEdgeInsetsMake(titleTopOffset, -CGRectGetWidth(imageView.bounds), 0, 0)
    }
}

This ought to do the trick: just limit the result to 1 row; if a row comes back the $lectureName is Assigned, otherwise it's Available.

function checkLectureStatus($lectureName)
{
    $con = connectvar();
    mysql_select_db("mydatabase", $con);
    $result = mysql_query(
        "SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");

    if(mysql_fetch_array($result) !== false)
        return 'Assigned';
    return 'Available';
}

In php 7 you can do:

$_POST['value'] ?? null;

If value is equal to '' as said in other answers it will also send you null.

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

To make a robust form, have it load in a useful state and use script to enhance its behaviour. In the following, the select has been replaced by radio buttons (makes life much easier for the user).

The "yes" option is checked by default and the select is enabled. If the user checks either radio button, the select is enabled or disabled accordingly.

<form onclick="this.mySelect1.disabled = this.becomeMember[1].checked;" ... >
  <input type="radio" name="becomeMember" checked>Yes<br>
  <input type="radio" name="becomeMember">No<br>

  <select id="mySelect1">
    <option>Dep1
    <option>Dep2
    <option>Dep3
    <option>Dep4
  </select>
  ...
</form> 

void myFunc(char* str, char c)
{
    char* ptr;
    int index;

    ptr = strchr(str, c);
    if (ptr == NULL)
    {
        printf("Character not found\n");
        return;
    }

    index = ptr - str;

    printf("The index is %d\n", index);
    ASSERT(str[index] == c);  // Verify that the character at index is the one we want.
}

This code is currently untested, but it demonstrates the proper concept.

The reference you have listed for Ruby is for Ruby on Rails. While still ruby deep down, it is definitely not a place to start for people wanting to learn Ruby.

For Ruby tutorials, I would suggest Why's (Poignant) Guide to Ruby as a great starting point for anyone interested in the language.

If you would want to get into more detail, I would recommend the book Programming Ruby, which has become the standard for all things Ruby. The third edition is currently being written, highlighting Ruby 1.9 features, so I would hold off for a while if anyone is considering buying this book.

The List interface already has this solved.

int temp = 2;
if(bankAccNos.contains(bakAccNo)) temp=1;

More can be found in the documentation about List.

I did a bit of research regarding this & I have summarised my findings so far in below table

So the recommended solution is to write a a server side script to parse the Accept-Language header & pass it to client for setting the language of the website. It's weird that why the server would be needed to detect the language preference of client but that's how it is as of now There are other various hacks available to detect the language but reading the Accept-Language header is the recommended solution as per my understanding.

Current state: default implementation in docs

Currently there is a default implementation of input+dropdown combo in the documentation here (search for "Button dropdowns"). I leave the original solution for the record and for those who cannot use solution now included in the documentation.

Original solution

Yes, it is possible. As a matter of fact, there is one example in the Twitter Bootstrap documentation (follow the link and search "Examples" for dropdown buttons):

<div class="btn-group">
    <a class="btn btn-primary" href="#">
        <i class="icon-user icon-white"></i> User
    </a>
    <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#">
        <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
        <li><a href="#"><i class="icon-pencil"></i> Edit</a></li>
        <li><a href="#"><i class="icon-trash"></i> Delete</a></li>
        <li><a href="#"><i class="icon-ban-circle"></i> Ban</a></li>
        <li class="divider"></li>
        <li><a href="#"><i class="i"></i> Make admin</a></li>
    </ul>
</div>

If enclosed within text, it can look like this (with text on the button changed, nothing else):

EDIT:

If you are trying to achieve <input> with appended dropdown menu as in the dropdown buttons, then this is one of the solutions:

1. Add a btn-group class to the element that has input-append class,
2. Add elements with classes dropdown-toggle and dropdown-menu at the end of the element with class input-append,
3. Override style for element matching .input-append .btn.dropdown-menu so it does not have float: left (otherwise it will get into next line).

The resulting code may look like this:

<div class="input-append btn-group">
    <input class="span2" id="appendedInputButton" size="16" type="text">
    <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#">
        <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
        <li><a href="#"><i class="icon-pencil"></i> Edit</a></li>
        <li><a href="#"><i class="icon-trash"></i> Delete</a></li>
        <li><a href="#"><i class="icon-ban-circle"></i> Ban</a></li>
        <li class="divider"></li>
        <li><a href="#"><i class="i"></i> Make admin</a></li>
    </ul>
</div>

with a little support from this style override:

.input-append .btn.dropdown-toggle {
    float: none;
}

and give you the exact same result as this:

EDIT 2: Updated the CSS selector (was .dropdown-menu, is .dropdown-toggle).

You can use find and -exec directly into sed rather than first locating oldstr with grep. It's maybe a bit less efficient, but that might not be important. This way, the sed replacement is executed over all files listed by find, but if oldstr isn't there it obviously won't operate on it.

find /path -type f -exec sed -i 's/oldstr/newstr/g' {} \;

The string has a substring method that returns the string at the specified position.

String name="123456789";
System.out.println(name.substring(0,1));

From the C++ standard section 3.1:

A declaration introduces names into a translation unit or redeclares names introduced by previous declarations. A declaration specifies the interpretation and attributes of these names.

The next paragraph states (emphasis mine) that a declaration is a definition unless...

... it declares a function without specifying the function’s body:

void sqrt(double);  // declares sqrt

... it declares a static member within a class definition:

struct X
{
    int a;         // defines a
    static int b;  // declares b
};

... it declares a class name:

class Y;

... it contains the extern keyword without an initializer or function body:

extern const int i = 0;  // defines i
extern int j;  // declares j
extern "C"
{
    void foo();  // declares foo
}

... or is a typedef or using statement.

typedef long LONG_32;  // declares LONG_32
using namespace std;   // declares std

Now for the big reason why it's important to understand the difference between a declaration and definition: the One Definition Rule. From section 3.2.1 of the C++ standard:

No translation unit shall contain more than one definition of any variable, function, class type, enumeration type, or template.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

The same error occurred to me. I fixed it by turning off TLS for Composer, it's not safe but I assumed the risk on my develop machine.

try this:

composer config -g -- disable-tls true

and re-run your Composer. It works to me!

But it's unsecure and not recommended for your Server. The official website says:

If set to true all HTTPS URLs will be tried with HTTP instead and no network-level encryption is performed. Enabling this is a security risk and is NOT recommended. The better way is to enable the php_openssl extension in php.ini.

If you don't want to enable unsecure layer in your machine/server, then setup your php to enable openssl and it also works. Make sure the PHP Openssl extension has been installed and enable it on php.ini file.

To enable OpenSSL, add or find and uncomment this line on your php.ini file:

Linux/OSx:

extension=php_openssl.so

Windows:

extension=php_openssl.dll

And reload your php-fpm / web-server if needed!

From Oracle doc you can use -Xlog option that has a possibility to write into file.

java -Xlog:class+load=info:classloaded.txt

You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.

This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

When the rails server does not start it means that it is already running then you can start by using new port eg.

rails s -p 3001

or it starts and stops in that case you want to delete temp folder in rails directory structure it starts the rails server.

You can adjust the pane title by setting the pane border in the tmux.conf for example like this:

###############
# pane border #
###############
set -g pane-border-status bottom
#colors for pane borders
setw -g pane-border-style fg=green,bg=black
setw -g pane-active-border-style fg=colour118,bg=black
setw -g automatic-rename off
setw -g pane-border-format ' #{pane_index} #{pane_title} : #{pane_current_path} '
# active pane normal, other shaded out?
setw -g window-style fg=colour28,bg=colour16
setw -g window-active-style fg=colour46,bg=colour16

Where pane_index, pane_title and pane_current_path are variables provided by tmux itself.

After reloading the config or starting a new tmux session, you can then set the title of the current pane like this:

tmux select-pane -T "fancy pane title";
#or
tmux select-pane -t paneIndexInteger -T "fancy pane title";

If all panes have some processes running, so you can't use the command line, you can also type the commands after pressing the prefix bind (C-b by default) and a colon (:) without having "tmux" in the front of the command:

select-pane -T "fancy pane title"
#or:
select-pane -t paneIndexInteger -T "fancy pane title"

This line calls the selector secondMethod after 3 seconds:

[self performSelector:@selector(secondMethod) withObject:nil afterDelay:3.0 ];

Use it on your second operation with your desired delay. If you have a lot of code, place it in its own method and call that method with performSelector:. It wont block the UI like sleep

Edit: If you do not want a second method you could add a category to be able to use blocks with performSelector:

@implementation NSObject (PerformBlockAfterDelay)

- (void)performBlock:(void (^)(void))block 
          afterDelay:(NSTimeInterval)delay
{
    block = [block copy];
    [self performSelector:@selector(fireBlockAfterDelay:) 
               withObject:block 
               afterDelay:delay];
}

- (void)fireBlockAfterDelay:(void (^)(void))block
{
    block();
}

@end

Or perhaps even cleaner:

void RunBlockAfterDelay(NSTimeInterval delay, void (^block)(void))
{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC*delay),
      dispatch_get_current_queue(), block);
}

In my case (sam problem, but other packages) there was no version dependency. A sequence of pip uninstall and pip insstall did help.

math.sqrt is the C implementation of square root and is therefore different from using the ** operator which implements Python's built-in pow function. Thus, using math.sqrt actually gives a different answer than using the ** operator and there is indeed a computational reason to prefer numpy or math module implementation over the built-in. Specifically the sqrt functions are probably implemented in the most efficient way possible whereas ** operates over a large number of bases and exponents and is probably unoptimized for the specific case of square root. On the other hand, the built-in pow function handles a few extra cases like "complex numbers, unbounded integer powers, and modular exponentiation".

See this Stack Overflow question for more information on the difference between ** and math.sqrt.

In terms of which is more "Pythonic", I think we need to discuss the very definition of that word. From the official Python glossary, it states that a piece of code or idea is Pythonic if it "closely follows the most common idioms of the Python language, rather than implementing code using concepts common to other languages." In every single other language I can think of, there is some math module with basic square root functions. However there are languages that lack a power operator like ** e.g. C++. So ** is probably more Pythonic, but whether or not it's objectively better depends on the use case.

In case anyone else stumbles on this, I was using File.ReadAllText to get CSV data and then I modified it and wrote it back with File.WriteAllText. The \r\n CRLFs were fine but the \t tabs were ignored when Excel opened it. (All solutions in this thread so far use a comma delimiter but that doesn't matter.) Notepad showed the same format in the resulting file as in the source. A Diff even showed the files as identical. But I got a clue when I opened the file in Visual Studio with a binary editor. The source file was Unicode but the target was ASCII. To fix, I modified both ReadAllText and WriteAllText with third argument set as System.Text.Encoding.Unicode, and from there Excel was able to open the updated file.

It seems that most of the answers missed the original question.

Is there a standard sign function (signum, sgn) in C/C++?

Not in the standard library, however there is copysign which can be used almost the same way via copysign(1.0, arg) and there is a true sign function in boost, which might as well be part of the standard.

    #include <boost/math/special_functions/sign.hpp>

    //Returns 1 if x > 0, -1 if x < 0, and 0 if x is zero.
    template <class T>
    inline int sign (const T& z);

http://www.boost.org/doc/libs/1_47_0/libs/math/doc/sf_and_dist/html/math_toolkit/utils/sign_functions.html

num = int(input('Size of elements : '))
arr = list()

for i in range(num) :
  ele  = int(input())
  arr.append(ele)

print(arr)

Even if that's a 7 years old question, people new to R should consider using the data.table, package.

A data.table is a data.frame so all you can do for/to a data.frame you can also do. But many think are ORDERS of magnitude faster with data.table.

vec <- 1:10
library(data.table)
DT <- data.table(start=c(1,3,5,7), end=c(2,6,7,9))
DT[,new:=apply(DT,1,function(row) mean(vec[ row[1] : row[2] ] ))]

For Current Date and Time :

String mydate = java.text.DateFormat.getDateTimeInstance().format(Calendar.getInstance().getTime());

This will shown as :

I tried many GUI's, and the best for me continue being "SQLyog-comunity" by using wine. Is complete, is nice, and is intuitive. (and in wine work perfect)

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

I wouldn't go so far as @Femi to change the existing address property. You can add new services to the definitions section easily.

<wsdl:service name="serviceMethodName_2">
  <wsdl:port binding="tns:serviceMethodNameSoapBinding" name="serviceMethodName">
    <soap:address location="http://new_end_point_adress"/>
  </wsdl:port>
</wsdl:service>

This doesn't require a recompile of the WSDL to Java and making updates isn't any more difficult than if you used the BindingProvider option (which didn't work for me btw).

Just put DROP TABLE IF EXISTS `tablename`; before your CREATE TABLE statement.

That statement drops the table if it exists but will not throw an error if it does not.

I find marking the property as readonly cleaner than the above answers. I believe vb14 is required.

Private _Name As String

Public ReadOnly Property Name() As String
    Get
        Return _Name
    End Get
End Property

This can be condensed to

Public ReadOnly Property Name As String

This is long settled, but I ran across this answer because I was experiencing an unexpected error while reading a CSV to process as training data in Keras and TensorFlow.

In my case, the issue was much simpler, and is worth being conscious of. The data being produced into the CSV wasn't consistent, resulting in some columns being completely missing, which seems to end up throwing this error as well.

The lesson: If you're seeing this error, verify that your data looks the way that you think it does!

Just pass UTC date format from your server side code to client side

and use below syntax -

 {{dateUTCField  +'Z' | date : 'mm/dd/yyyy'}}

 e.g. dateUTCField = '2018-01-09T10:02:32.273' then it display like 01/09/2018

The behaviour is different depending upon the database configuration. In the strict mode this would throw an error else a warning. Following query may be used for identifying the database configuration.

mysql> show variables like 'sql_mode';

Below is the code worked for me, And we need to be very careful for format. Below link will be definitely useful for knowing your exiting format and changing into desired format(Follow strftime() and strptime() Format Codes on below link):

https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior.

data['date_new_format'] = pd.to_datetime(data['date_to_be_changed'] , format='%b-%y')

Use a repository manager and install this kind of jars into it. That solves your problems at all and for all computers in your network.

import csv

dict = {"Key Header":"Value Header", "key1":"value1", "key2":"value2"}

with open("test.csv", "w") as f:
    writer = csv.writer(f)
    for i in dict:
      writer.writerow([i, dict[i]])
f.close() 

If you will place your definitions in this order then the code will be compiled

class Ball;

class Player {
public:
    void doSomething(Ball& ball);
private:
};

class Ball {
public:
    Player& PlayerB;
    float ballPosX = 800;
private:

};

void Player::doSomething(Ball& ball) {
    ball.ballPosX += 10;                   // incomplete type error occurs here.
}

int main()
{
}

The definition of function doSomething requires the complete definition of class Ball because it access its data member.

In your code example module Player.cpp has no access to the definition of class Ball so the compiler issues an error.

Your problem may be solved if you give your div a fixed width, as follows:

div#thing {
    position: absolute;
    top: 0px;
    z-index: 2;
    width:400px;
    margin-left:-200px;
    left:50%;
}

Question 1: Use .delegate on the div to bind a click handler to the button.

Question 2: Use $(this).val() or this.value (the latter would be faster) inside of the click handler. this will refer to the button.

$("#pg_menu_content").on('click', '#btn_a', function () {
  alert($(this).val());
});

$div = $('<div data-role="fieldcontain"/>');
$("<input type='button' value='Dynamic Button' id='btn_a' />").appendTo($div.clone()).appendTo('#pg_menu_content');

The readr package has a function to do everything for you.

install.packages("readr") # you only need to do this one time on your system
library(readr)
mystring <- read_file("path/to/myfile.txt")

This replaces the version in the package stringr.

It is now possible to use Wireshark directly to capture Android emulator traffic. There is an extcap plugin called androiddump which makes it possible. You need to have a tcpdump executable in the system image running on the emulator (most current images have it, tested with API 24 and API 27 images) and adbd running as root on the host (just run adb root). In the list of the available interfaces in Wireshark (Qt version only, the deprecated GTK+ doesn't have it) or the list shown with tshark -D there should be several Android interfaces allowing to sniff Bluetooth, Logcat, or Wifi traffic, e.g.:

android-wifi-tcpdump-emulator-5554 (Android WiFi Android_SDK_built_for_x86 emulator-5554)

Use sp_executesql to execute any SQL, e.g.

What worked for me, I clear the opacity in .modal.backdrop.in

.modal-backdrop.in{
    filter:alpha(opacity=50);
    opacity:.5
    }

change it to

.modal-backdrop.in{
   }

Here's my own take at it based on the xpath of the element created :

/** Returns the XPATH of an element **/
var getPathTo = function(element) {
  if (element===document.body)
      return element.tagName;

  var ix= 0;
  var siblings= element.parentNode.childNodes;
  for (var i= 0; i<siblings.length; i++) {
      var sibling= siblings[i];
      if (sibling===element)
          // stripped xpath (parent xpath + tagname + index)
          return getPathTo(element.parentNode)+ element.tagName + ix+1;
      if (sibling.nodeType===1 && sibling.tagName===element.tagName)
          ix++;
   }
}

/** hashcode function (credit http://stackoverflow.com/questions/7616461/generate-a-hash-from-string-in-javascript-jquery **/
var hashCode = function(str) {
  var hash = 0, i, chr, len;
  if (str.length === 0) return hash;
  for (i = 0, len = str.length; i < len; i++) {
    chr   = str.charCodeAt(i);
    hash  = ((hash << 5) - hash) + chr;
    hash |= 0; // Convert to 32bit integer
 }
return hash;
};

/** Genaretes according to xpath + timestamp **/
var generateUID = function(ele)
{
  return hashCode(getPathTo(ele)) + new Date().getTime();
}

First the xpath of the element is fetched.

The hashcode of the xpath is then computed. We therefore have a unique id per xpath.

The problem here is that xpath are not necesseraly unique if unique elements are generated on the fly. Thus we add the timestamp at the end.

Maybe we could also garantee more unique elements by adding a final Math.Random().

Create the classLoader instance of the class you need, then you can access the files or resources easily. now you access path using getPath() method of that class.

 ClassLoader classLoader = getClass().getClassLoader();
 String path  = classLoader.getResource("chromedriver.exe").getPath();
 System.out.println(path);

Unwrap and downcast the objects to the right type, safely, with if let, before doing the iteration with a simple for in loop.

if let currentUser = currentUser, 
    let photos = currentUser.photos as? [ModelAttachment] 
{
    for object in photos {
        let url = object.url
    }
}

There's also guard let else instead of if let if you prefer having the result available in scope:

guard let currentUser = currentUser, 
    let photos = currentUser.photos as? [ModelAttachment] else 
{
    // break or return
}
// now 'photos' is available outside the guard
for object in photos {
    let url = object.url
}

If you are referring to the actual MySQL users, try:

select User from mysql.user;

undefined index means that somewhere in the $_POST array, there isn't an index (key) for the key username.

You should be setting your posted values into variables for a more clean solution, and it's a good habit to get into.

If I was having a similar error, I'd do something like this:

$username = $_POST['username']; // you should really do some more logic to see if it's set first
echo $username;

If username didn't turn up, that'd mean I was screwing up somewhere. You can also,

var_dump($_POST);

To see what you're posting. var_dump is really useful as far as debugging. Check it out: var_dump

I think you're just looking for the overload which takes another Collector to specify what to do with each group... and then Collectors.counting() to do the counting:

import java.util.*;
import java.util.stream.*;

class Test {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();

        list.add("Hello");
        list.add("Hello");
        list.add("World");

        Map<String, Long> counted = list.stream()
            .collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));

        System.out.println(counted);
    }
}

Result:

{Hello=2, World=1}

(There's also the possibility of using groupingByConcurrent for more efficiency. Something to bear in mind for your real code, if it would be safe in your context.)

Thought I'd write exactly what I did (Windows 10, 64-bit):

From the download page https://curl.haxx.se/download.html choose the download wizard https://curl.haxx.se/dlwiz/

Choose curl executable.

Choose Win64.

Choose generic.

Choose any.

Choose x86_64.

Choose the first recommended option. For me this was:

curl version: 7.53.1 - SSL enabled SSH enabled. Provided by: Viktor Szakáts. This package is type curl executable You will get a pre-built 'curl' binary from this link (or in some cases, by using the information that is provided at the page this link takes you). You may or may not get 'libcurl' installed as a shared library/DLL. The file is packaged using 7zip. 7zip is a file archiving format.

Click download.

You should have the file curl-7.53.1-win64-mingw.7z in your downloads folder.

Install 7-Zip if you don't have it.

Right-click, 7-Zip, Extract Here. Copy and paste the extracted file somewhere like Z:\Tools\

If you look in the bin folder you'll see curl.exe. If you double-click it a window will quickly flash up and vanish. To run it you need to use the Command Prompt. Navigate to the bin folder and type curl followed by your parameters to make a request. You must use double-quotes. Single quotes won't work with curl on Windows.

Now you'll want to add curl to a user's Path variable so you don't have to navigate to the right folder to run the program. Go to This PC, Computer, System Properties, Advanced system settings, authenticate as an administrator (you're not running as admin, right? Right?) Environment Variables, System variables, look at the list and select Path, then Edit, then New, then, e.g.

Z:\Tools\curl-7.53.1-win64-mingw\bin

You can add a trailing backslash if you like, I don't think it matters. Click move up until it's at the top of the list, then you can see it easily from the previous screen. Click OK, OK, OK, then crack open a Command Prompt and you can run curl by typing curl from any folder, as any user. Don't forget your double-quotes.

This is the answer I wish I'd had.

Data.frame[,'h_new_column'] <- as.integer(Data.frame[,'h_no'], breaks=c(1, 4, 7))

Use Bash and the date command to convert from an ISO-like format to the one you want. I wanted an org-mode date format (and list item), so I did this:

echo + [$(date -d "$(git log --pretty=format:%ai -1)" +"%Y-%m-%d %a %H:%M")] \
    $(git log --pretty=format:"%h %s" --abbrev=12 -1)

And the result is for example:

+ [2015-09-13 Sun 22:44] 2b0ad02e6cec Merge pull request #72 from 3b/bug-1474631

As myJSON is an object you can just set its properties, for example:

myJSON.list1 = ["1","2"];

If you dont know the name of the properties, you have to use the array access syntax:

myJSON['list'+listnum] = ["1","2"];

If you want to add an element to one of the properties, you can do;

myJSON.list1.push("3");

Actually, you probably want to use utf8_unicode_ci or utf8_general_ci.

• utf8_general_ci sorts by stripping away all accents and sorting as if it were ASCII
• utf8_unicode_ci uses the Unicode sort order, so it sorts correctly in more languages

However, if you are only using this to store English text, these shouldn't differ.

One of the best ways I find for approximating the complexity of the recursive algorithm is drawing the recursion tree. Once you have the recursive tree:

Complexity = length of tree from root node to leaf node * number of leaf nodes

1. The first function will have length of n and number of leaf node 1 so complexity will be n*1 = n

2. The second function will have the length of n/5 and number of leaf nodes again 1 so complexity will be n/5 * 1 = n/5. It should be approximated to n

3. For the third function, since n is being divided by 5 on every recursive call, length of recursive tree will be log(n)(base 5), and number of leaf nodes again 1 so complexity will be log(n)(base 5) * 1 = log(n)(base 5)

4. For the fourth function since every node will have two child nodes, the number of leaf nodes will be equal to (2^n) and length of the recursive tree will be n so complexity will be (2^n) * n. But since n is insignificant in front of (2^n), it can be ignored and complexity can be only said to be (2^n).

5. For the fifth function, there are two elements introducing the complexity. Complexity introduced by recursive nature of function and complexity introduced by for loop in each function. Doing the above calculation, the complexity introduced by recursive nature of function will be ~ n and complexity due to for loop n. Total complexity will be n*n.

Note: This is a quick and dirty way of calculating complexity(nothing official!). Would love to hear feedback on this. Thanks.

None of the solutions above worked for me because I was using Formik and I needed to mark the field "touched" along with changing the field value. Following code worked for me.

const emailField = orderPageWrapper.find('input[name="email"]')

emailField.simulate('focus')
emailField.simulate('change', { target: { value: '[email protected]', name: 'email' } })
emailField.simulate('blur')

You can use import nbimporter then import notebookName

Ports

The ports section will publish ports on the host. Docker will setup a forward for a specific port from the host network into the container. By default this is implemented with a userspace proxy process (docker-proxy) that listens on the first port, and forwards into the container, which needs to listen on the second point. If the container is not listening on the destination port, you will still see something listening on the host, but get a connection refused if you try to connect to that host port, from the failed forward into your container.

Note, the container must be listening on all network interfaces since this proxy is not running within the container's network namespace and cannot reach 127.0.0.1 inside the container. The IPv4 method for that is to configure your application to listen on 0.0.0.0.

Also note that published ports do not work in the opposite direction. You cannot connect to a service on the host from the container by publishing a port. Instead you'll find docker errors trying to listen to the already-in-use host port.

Expose

Expose is documentation. It sets metadata on the image, and when running, on the container too. Typically you configure this in the Dockerfile with the EXPOSE instruction, and it serves as documentation for the users running your image, for them to know on which ports by default your application will be listening. When configured with a compose file, this metadata is only set on the container. You can see the exposed ports when you run a docker inspect on the image or container.

There are a few tools that rely on exposed ports. In docker, the -P flag will publish all exposed ports onto ephemeral ports on the host. There are also various reverse proxies that will default to using an exposed port when sending traffic to your application if you do not explicitly set the container port.

Other than those external tools, expose has no impact at all on the networking between containers. You only need a common docker network, and connecting to the container port, to access one container from another. If that network is user created (e.g. not the default bridge network named bridge), you can use DNS to connect to the other containers.

Well splice works:

var arr = [{id:1,name:'serdar'}];
arr.splice(0,1);
// []

Do NOT use the delete operator on Arrays. delete will not remove an entry from an Array, it will simply replace it with undefined.

var arr = [0,1,2];
delete arr[1];
// [0, undefined, 2]

But maybe you want something like this?

var removeByAttr = function(arr, attr, value){
    var i = arr.length;
    while(i--){
       if( arr[i] 
           && arr[i].hasOwnProperty(attr) 
           && (arguments.length > 2 && arr[i][attr] === value ) ){ 

           arr.splice(i,1);

       }
    }
    return arr;
}

Just an example below.

var arr = [{id:1,name:'serdar'}, {id:2,name:'alfalfa'},{id:3,name:'joe'}];
removeByAttr(arr, 'id', 1);   
// [{id:2,name:'alfalfa'}, {id:3,name:'joe'}]

removeByAttr(arr, 'name', 'joe');
// [{id:2,name:'alfalfa'}]

I see this question is already answered, but wanted to offer an alternative in case someone else finds this later.

Depending on the required delimiter, it is possible to do this without writing any code. The original question does not give details on the desired output type but here is an alternative:

PRN File Type

The easiest option is to save the file as a "Formatted Text (Space Delimited)" type. The VBA code line would look similar to this:

ActiveWorkbook.SaveAs FileName:=myFileName, FileFormat:=xlTextPrinter, CreateBackup:=False

In Excel 2007, this will annoyingly put a .prn file extension on the end of the filename, but it can be changed to .txt by renaming manually.

In Excel 2010, you can specify any file extension you want in the Save As dialog.

One important thing to note: the number of delimiters used in the text file is related to the width of the Excel column.

Observe:

Becomes:

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

I know why, you are using the file name "ping" and you are using the code "ping", it just keeps trying to run itself because its selected directory in where that file is, if you want it to actually ping, put this before the ping command: "cd C:\Windows\system32", the actual file that pings the server is in there!

The old way:

xcopy [source] [destination] /E

xcopy is deprecated. Robocopy replaces Xcopy. It comes with Windows 8, 8.1 and 10.

robocopy [source] [destination] /E

robocopy has several advantages:

• copy paths exceeding 259 characters
• multithreaded copying

More details here.

If you are using Java 1.6 or greater, you can use Arrays.copyOfRange to copy a portion of the array. From the javadoc:

Copies the specified range of the specified array into a new array. The initial index of the range (from) must lie between zero and original.length, inclusive. The value at original[from] is placed into the initial element of the copy (unless from == original.length or from == to). Values from subsequent elements in the original array are placed into subsequent elements in the copy. The final index of the range (to), which must be greater than or equal to from, may be greater than original.length, in which case false is placed in all elements of the copy whose index is greater than or equal to original.length - from. The length of the returned array will be to - from.

Here is a simple example:

/**
 * @Program that Copies the specified range of the specified array into a new 
 * array.
 * CopyofRange8Array.java 
 * Author:-RoseIndia Team
 * Date:-15-May-2008
 */
import java.util.*;
public class CopyofRange8Array {
    public static void main(String[] args) {
       //creating a short array
       Object T[]={"Rose","India","Net","Limited","Rohini"};
        // //Copies the specified  short array upto specified range,
        Object T1[] = Arrays.copyOfRange(T, 1,5);
        for (int i = 0; i < T1.length; i++) 
            //Displaying the Copied short array upto specified range
            System.out.println(T1[i]);
    }

}

class Test
{
    Dictionary<int, string> entities;

    public string GetEntity(int code)
    {
        // java's get method returns null when the key has no mapping
        // so we'll do the same

        string val;
        if (entities.TryGetValue(code, out val))
            return val;
        else
            return null;
    }
}

This worked for me.

There are several ways to UPDATE using sqlalchemy

1) user.no_of_logins += 1
   session.commit()

2) session.query().\
       filter(User.username == form.username.data).\
       update({"no_of_logins": (User.no_of_logins +1)})
   session.commit()

3) conn = engine.connect()
   stmt = User.update().\
       values(no_of_logins=(User.no_of_logins + 1)).\
       where(User.username == form.username.data)
   conn.execute(stmt)

4) setattr(user, 'no_of_logins', user.no_of_logins+1)
   session.commit()

If you use HashSet instead of List for listofGenres you can do:

var genres = new HashSet<Genre>() { "action", "comedy" };   
var movies = _db.Movies.Where(p => genres.Overlaps(p.Genres));

Without using itertools:

In Python 3 you can use yield from to add a subset generator method to buit-in set class:

class SetWithSubset(set):
    def subsets(self):
        s1 = []
        s2 = list(self)

        def recfunc(i=0):            
            if i == len(s2):
                yield frozenset(s1)
            else:                
                yield from recfunc(i + 1)
                s1.append(s2[ i ])
                yield from recfunc(i + 1)
                s1.pop()

        yield from recfunc()

For example below snippet works as expected:

x = SetWithSubset({1,2,3,5,6})
{2,3} in x.subsets()            # True
set() in x.subsets()            # True
x in x.subsets()                # True
x|{7} in x.subsets()            # False
set([5,3]) in x.subsets()       # True - better alternative: set([5,3]) < x
len(x.subsets())                # 32

Run these commands for Beyond Compare 2:

git config --global diff.tool bc2
git config --global difftool.bc2.cmd "\"c:/program files (x86)/beyond compare 2/bc2.exe\" \"$LOCAL\" \"$REMOTE\""
git config --global difftool.prompt false

Run these commands for Beyond Compare 3:

git config --global diff.tool bc3
git config --global difftool.bc3.cmd "\"c:/program files (x86)/beyond compare 3/bcomp.exe\" \"$LOCAL\" \"$REMOTE\""
git config --global difftool.prompt false

Then use git difftool

I would like to point out to you that .val() also works with selects to select the current selected value.

String filePath = folder.getAbsolutePath()+ "/logcat.txt"; 
Runtime.getRuntime().exec(new String[]{"logcat", "-f", filePath, "MyAppTAG:V", "*:E"});

if you're doing a lot of this kind of thing you should consider using numpy.

In [56]: import random, numpy

In [57]: lst = numpy.array([random.uniform(0, 5) for _ in range(1000)]) # example list

In [58]: a, b = 1, 3

In [59]: numpy.flatnonzero((lst > a) & (lst < b))[:10]
Out[59]: array([ 0, 12, 13, 15, 18, 19, 23, 24, 26, 29])

In response to Seanny123's question, I used this timing code:

import numpy, timeit, random

a, b = 1, 3

lst = numpy.array([random.uniform(0, 5) for _ in range(1000)])

def numpy_way():
    numpy.flatnonzero((lst > 1) & (lst < 3))[:10]

def list_comprehension():
    [e for e in lst if 1 < e < 3][:10]

print timeit.timeit(numpy_way)
print timeit.timeit(list_comprehension)

The numpy version is over 60 times faster.

netstat -ano|grep 443|grep LISTEN

will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).

SELECT p.*, f.Fear
FROM Persons p
LEFT JOIN Person_Fear pf ON pf.PersonID = p.PersonID
LEFT JOIN Fears f ON f.FearID = pf.FearID
ORDER BY p.PersonID

1. You need to select from the Persons table to ensure you generate a row for every person, whether they have fears or not.
2. Then you can left join Person_Fear to every person, which will just be NULL if they don't have any entries (as you want).
3. Finally, you left join Fears on Person_Fear so that you can select the name of the fear.
4. Optionally, add an order so that each person has all their fears listed together, even if they were added to the Person_Fear table at different times.

In my case the user agent was not good enought since in the Ipad the user agent was the same as in Mac OS, therefore I had to do a nasty trick:

var mql = window.matchMedia("(orientation: landscape)");

/**
 * If we are in landscape but the height is bigger than width
 */
if(mql.matches && window.screen.height > window.screen.width) {
    // IOS
} else {
    // Mac OS
}

see http://editorconfig.org and https://docs.microsoft.com/en-us/visualstudio/ide/create-portable-custom-editor-options?view=vs-2017

1. If it does not exist, add a new file called .editorconfig for your project

2. manipulate editor config to use your preferred behaviour.

I prefer spaces over tabs, and CRLF for all code files.
Here's my .editorconfig

# http://editorconfig.org
root = true

[*]
indent_style = space
indent_size = 4
end_of_line = crlf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.md]
trim_trailing_whitespace = false

[*.tmpl.html]
indent_size = 4

[*.scss]
indent_size = 2 

You can use vi editor. Type:

vi -o mysql.dump mytable.dump

to open both whole dump mysql.dump and a new file mytable.dump. Find the appropriate insert into line by pressing / and then type a phrase, for example: "insert into `mytable`", then copy that line using yy. Switch to next file by ctrl+w then down arrow key, paste the copied line with pp. Finally save the new file by typing :wq and quite vi editor by :q.

Note that if you have dumped the data using multiple inserts you can copy (yank) all of them at once using Nyy in which N is the number of lines to be copied.

I have done it with a file of 920 MB size.

If you have GNU coreutils installed, consider %!unexpand --first-only or for 4-space tabs, consider %!unexpand -t 4 --first-only (--first-only is present just in case you were accidentally invoking unexpand with --all).

Note that this will only replace the spaces preceding the prescribed tab stops, not the spaces that follow them; you will see no visual difference in vim unless you display tabs more literally; for example, my ~/.vimrc contains set list listchars=tab:?? (I suspect this is why you thought unexpand didn't work).

I think you are looking for this function:

http://doc.qt.io/qt-5/qdatetime.html#toTime_t

uint QDateTime::toTime_t () const

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).

On systems that do not support time zones, this function will behave as if local time were Qt::UTC.

See also setTime_t().

Your selector won't select the input field, and if it did it would return a jQuery object. Try this:

$('#test2').is(':checked'); 

Here is an example:

$.ajax({
        type: "post",
        url: "ajax/example.php",
        data: 'page=' + btn_page,
        success: function (data) {
            var a = data; // This line shows error.
            $.ajax({
                type: "post",
                url: "example.php",
                data: 'page=' + a,
                success: function (data) {

                }
            });
        }

Taken from the latest stable Oracle production version 12.2: Data Types

The major difference is that VARCHAR2 is an internal data type and VARCHAR is an external data type. So we need to understand the difference between an internal and external data type...

Inside a database, values are stored in columns in tables. Internally, Oracle represents data in particular formats known as internal data types.

In general, OCI (Oracle Call Interface) applications do not work with internal data type representations of data, but with host language data types that are predefined by the language in which they are written. When data is transferred between an OCI client application and a database table, the OCI libraries convert the data between internal data types and external data types.

External types provide a convenience for the programmer by making it possible to work with host language types instead of proprietary data formats. OCI can perform a wide range of data type conversions when transferring data between an Oracle database and an OCI application. There are more OCI external data types than Oracle internal data types.

The VARCHAR2 data type is a variable-length string of characters with a maximum length of 4000 bytes. If the init.ora parameter max_string_size is default, the maximum length of a VARCHAR2 can be 4000 bytes. If the init.ora parameter max_string_size = extended, the maximum length of a VARCHAR2 can be 32767 bytes

The VARCHAR data type stores character strings of varying length. The first 2 bytes contain the length of the character string, and the remaining bytes contain the string. The specified length of the string in a bind or a define call must include the two length bytes, so the largest VARCHAR string that can be received or sent is 65533 bytes long, not 65535.

A quick test in a 12.2 database suggests that as an internal data type, Oracle still treats a VARCHAR as a pseudotype for VARCHAR2. It is NOT a SYNONYM which is an actual object type in Oracle.

SQL> select substr(banner,1,80) from v$version where rownum=1;
Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production    

SQL> create table test (my_char varchar(20));
Table created.

SQL> desc test
Name                 Null?    Type
MY_CHAR                       VARCHAR2(20)

There are also some implications of VARCHAR for ProC/C++ Precompiler options. For programmers who are interested, the link is at: Pro*C/C++ Programmer's Guide

Go to installed updates and just uninstall Internet Explorer 11 Windows update. It works for me.

Update for ECMAScript 2017:

Math.clamp(x, lower, upper)

But note that as of today, it's a Stage 1 proposal. Until it gets widely supported, you can use a polyfill.

I believe that it is virtually never correct to use nolock.

If you are reading a single row, then the correct index means that you won't need NOLOCK as individual row actions are completed quickly.

If you are reading many rows for anything other than temporary display, and care about being able repeat the result, or defend by the number produced, then NOLOCK is not appropriate.

NOLOCK is a surrogate tag for "i don't care if this answer contains duplicate rows, rows which are deleted, or rows which were never inserted to begin with because of rollback"

Errors which are possible under NOLOCK:

• Rows which match are not returned at all.
• single rows are returned multiple times (including multiple instances of the same primary key)
• Rows which do not match are returned.

Any action which can cause a page split while the noLock select is running can cause these things to occur. Almost any action (even a delete) can cause a page split.

Therefore: if you "know" that the row won't be changed while you are running, don't use nolock, as an index will allow efficient retrieval.

If you suspect the row can change while the query is running, and you care about accuracy, don't use nolock.

If you are considering NOLOCK because of deadlocks, examine the query plan structure for unexpected table scans, trace the deadlocks and see why they occur. NOLOCK around writes can mean that queries which previously deadlocked will potentially both write the wrong answer.

As pointed above, BFS can only be used to find shortest path in a graph if:

1. There are no loops

2. All edges have same weight or no weight.

To find the shortest path, all you have to do is start from the source and perform a breadth first search and stop when you find your destination Node. The only additional thing you need to do is have an array previous[n] which will store the previous node for every node visited. The previous of source can be null.

To print the path, simple loop through the previous[] array from source till you reach destination and print the nodes. DFS can also be used to find the shortest path in a graph under similar conditions.

However, if the graph is more complex, containing weighted edges and loops, then we need a more sophisticated version of BFS, i.e. Dijkstra's algorithm.

Avoid the for loopfor XY in xy: Instead read up how the numpy arrays are indexed and handled.

Also try and avoid .txt files if you are dealing with matrices. Try to use .csv or .npy files, and use Pandas dataframework to load them just for clarity.

I would extend this question with a NDIS driver example on getting time. As one knows, KeQuerySystemTime (mimicked under NdisGetCurrentSystemTime) has a low resolution above milliseconds, and there are some processes like network packets or other IRPs which may need a better timestamp;

The example is just as simple:

LONG_INTEGER data, frequency;
LONGLONG diff;
data = KeQueryPerformanceCounter((LARGE_INTEGER *)&frequency)
diff = data.QuadPart / (Frequency.QuadPart/$divisor)

where divisor is 10^3, or 10^6 depending on required resolution.

Remember that your suggestions makes it difficult for clients to communicate with the server. They need to understand your innovative solution and encrypt the data accordingly, this model is not so good for public API (unless you are amazon\yahoo\google..).

console.log has nothing to do with jQuery.

It logs a message to a debugging console, such as Firebug.

DECLARE @ADate Date, @ATime Time, @ADateTime Datetime

SELECT @ADate = '2010-02-20', @ATime = '18:53:00.0000000'

SET @ADateTime = CAST   (
    CONVERT(Varchar(10), @ADate, 112) + ' ' +   
    CONVERT(Varchar(8), @ATime) AS DateTime)

SELECT @ADateTime [A nice datetime :)]

This will render you a valid result.

I thought I lose all my hairs for solving this 'challenge'. I faced following problems:

1. How to deserialize nested objects, lists etc.
2. I like constructors with specified fields
3. I don't like dynamic fields
4. I don't like hacky solutions

I found a library called jsonpickle which is has proven to be really useful.

Installation:

pip install jsonpickle

Here is a code example with writing nested objects to file:

import jsonpickle


class SubObject:
    def __init__(self, sub_name, sub_age):
        self.sub_name = sub_name
        self.sub_age = sub_age


class TestClass:

    def __init__(self, name, age, sub_object):
        self.name = name
        self.age = age
        self.sub_object = sub_object


john_junior = SubObject("John jr.", 2)

john = TestClass("John", 21, john_junior)

file_name = 'JohnWithSon' + '.json'

john_string = jsonpickle.encode(john)

with open(file_name, 'w') as fp:
    fp.write(john_string)

john_from_file = open(file_name).read()

test_class_2 = jsonpickle.decode(john_from_file)

print(test_class_2.name)
print(test_class_2.age)
print(test_class_2.sub_object.sub_name)

Output:

John
21
John jr.

by the way, the zoo package, if it is loaded, overrides the base as.Date() with its own which, by default, provides origin="1970-01-01".

BEGIN
select * from tableName 
         (add joins OR sub query as per your requirement)
         Where (where condition here)
END $$
DELIMITER ;

To call this procedure use this query :

call procedureName(); // without parameter
call procedureName(id,pid); // with parameter

Detail :

1) DEFINER : root is the user name and change it as per your username of mysql localhost is the host you can change it with ip address of the server if you are execute this query on hosting server.

DataFrames are based on RDDs. RDDs are immutable structures and do not allow updating elements on-site. To change values, you will need to create a new DataFrame by transforming the original one either using the SQL-like DSL or RDD operations like map.

A highly recommended slide deck: Introducing DataFrames in Spark for Large Scale Data Science.

This is the proper way to do it:

INSERT INTO destinationTable
SELECT * FROM sourceTable

To get the max of any column you want something like:

max(ozone$Ozone, na.rm = TRUE)

To get the max of all columns, you want:

apply(ozone, 2, function(x) max(x, na.rm = TRUE))

And to sort:

ozone[order(ozone$Solar.R),]

Or to sort the other direction:

ozone[rev(order(ozone$Solar.R)),]

Ls is designed for human consumption, and you should not parse its output.

In shell scripts, there are a few cases where parsing the output of ls does work is the simplest way of achieving the desired effect. Since ls might mangle non-ASCII and control characters in file names, these cases are a subset of those that do not require obtaining a file name from ls.

In python, there is absolutely no reason to invoke ls. Python has all of ls's functionality built-in. Use os.listdir to list the contents of a directory and os.stat or os to obtain file metadata. Other functions in the os modules are likely to be relevant to your problem as well.

If you're accessing remote files over ssh, a reasonably robust way of listing file names is through sftp:

echo ls -1 | sftp remote-site:dir

This prints one file name per line, and unlike the ls utility, sftp does not mangle nonprintable characters. You will still not be able to reliably list directories where a file name contains a newline, but that's rarely done (remember this as a potential security issue, not a usability issue).

In python (beware that shell metacharacters must be escapes in remote_dir):

command_line = "echo ls -1 | sftp " + remote_site + ":" + remote_dir
remote_files = os.popen(command_line).read().split("\n")

For more complex interactions, look up sftp's batch mode in the documentation.

On some systems (Linux, Mac OS X, perhaps some other unices, but definitely not Windows), a different approach is to mount a remote filesystem through ssh with sshfs, and then work locally.

Yet another option would be:

SELECT * FROM mytable
 WHERE TRUNC(mydate, 'YEAR') = TRUNC(SYSDATE, 'YEAR');

The default date format depends on the language setting for the database server. You can also change it per session, like:

set language french
select cast(getdate() as varchar(50))
-->
févr 8 2013 9:45AM

Read many answers and posts and determined the most accurate solution. Tested in Safari, Chrome, Firefox (desktop and iOS versions). First we need to detect Apple vendor and then exclude Chrome and Firefox (for iOS).

let isSafari = navigator.vendor.match(/apple/i) &&
             !navigator.userAgent.match(/crios/i) &&
             !navigator.userAgent.match(/fxios/i);

if (isSafari) {
  //
} else {
  //
}

The following worked for me:

Simply change from Release>Debug>Release (or vice-versa) and then publish.

No need for deleting, editing, publishing anything you don't need to.

mysqli_set_charset($con,"utf8");
$title = ' LEVEL – EXTENDED'; 
$newtitle = preg_replace('/[^(\x20-\x7F)]*/','', $title);     
echo $newtitle;

Result :  LEVEL EXTENDED

Many Strange Character be removed by applying below the mysql connection code. but in some circumstances of removing this type strange character like †you can use preg_replace above format.
