If you are a windows user and try to start py-script in cmd - don't forget to type python before filename.

python script.py

I have "No module named google" error if forget to type it.

You should never write code that concatenates SQL and parameters as string - this opens up your code to SQL injection which is a really serious security problem.

Use bind params - for a nice howto see here...

or_() function can be useful in case of unknown number of OR query components.

For example, let's assume that we are creating a REST service with few optional filters, that should return record if any of filters return true. On the other side, if parameter was not defined in a request, our query shouldn't change. Without or_() function we must do something like this:

query = Book.query
if filter.title and filter.author:
    query = query.filter((Book.title.ilike(filter.title))|(Book.author.ilike(filter.author)))
else if filter.title:
    query = query.filter(Book.title.ilike(filter.title))
else if filter.author:
    query = query.filter(Book.author.ilike(filter.author))

With or_() function it can be rewritten to:

query = Book.query
not_null_filters = []
if filter.title:
    not_null_filters.append(Book.title.ilike(filter.title))
if filter.author:
    not_null_filters.append(Book.author.ilike(filter.author))

if len(not_null_filters) > 0:
    query = query.filter(or_(*not_null_filters))

In my case the problem was having different architectures specified under different targets. I was building my application target with armv6, armv7 and cocos2d with Standard (amrv7). Go into build settings and make sure your architectures agree for all targets.

Modify Global.asax.cs, including the Application_Start event with:

Database.SetInitializer<YourDatabaseContext>(
 new DropCreateDatabaseIfModelChanges<YourDatabaseContext>());

See

• error_log — Send an error message somewhere

Example

error_log("You messed up!", 3, "/var/tmp/my-errors.log");

You can customize error handling with your own error handlers to call this function for you whenever an error or warning or whatever you need to log occurs. For additional information, please refer to the Chapter Error Handling in the PHP Manual

Html.Raw() returns IHtmlString, not the ordinary string. So, you cannot write them in opposite sides of : operator. Remove that .ToString() calling

@{int count = 0;}
@foreach (var item in Model.Resources)
{
    @(count <= 3 ? Html.Raw("<div class=\"resource-row\">"): Html.Raw("")) 
    // some code
    @(count <= 3 ? Html.Raw("</div>") : Html.Raw("")) 
    @(count++)

}

By the way, returning IHtmlString is the way MVC recognizes html content and does not encode it. Even if it hasn't caused compiler errors, calling ToString() would destroy meaning of Html.Raw()

Here is another CSS solution. its take less line of code.

ul li:before
{content:'\2713';
  display:inline-block;
  color:red;
  padding:0 6px 0 0;
  }
ul li{list-style-type:none;font-size:1em;}

<ul>
    <li>test1</li>
    <li>test</li>
</ul>

Here is the Demo link http://jsbin.com/keliguqi/1/

Thanks all. I took bits of each of your solutions and made my own.

The final working solution is:

<script type="text/javascript">
    $(document).ready(function(){
        $.ajax({
            url: '<?php bloginfo('template_url'); ?>/functions/twitter.php',
            data: "tweets=<?php echo $ct_tweets; ?>&account=<?php echo $ct_twitter; ?>",
            success: function(data) {
                $('#twitter-loader').remove();
                $('#twitter-container').html(data);
            }
        });
   });
</script>

Comparable is used to compare instances of your class. We can compare instances from many ways that is why we need to implement a method compareTo in order to know how (attributes) we want to compare instances.

Dog class:

package test;
import java.util.Arrays;

public class Main {

    public static void main(String[] args) {
        Dog d1 = new Dog("brutus");
        Dog d2 = new Dog("medor");
        Dog d3 = new Dog("ara");
        Dog[] dogs = new Dog[3];
        dogs[0] = d1;
        dogs[1] = d2;
        dogs[2] = d3;

        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * brutus
         * medor
         * ara
         */

        Arrays.sort(dogs, Dog.NameComparator);
        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * ara
         * medor
         * brutus
         */

    }
}

Main class:

package test;

import java.util.Arrays;

public class Main {

    public static void main(String[] args) {
        Dog d1 = new Dog("brutus");
        Dog d2 = new Dog("medor");
        Dog d3 = new Dog("ara");
        Dog[] dogs = new Dog[3];
        dogs[0] = d1;
        dogs[1] = d2;
        dogs[2] = d3;

        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * brutus
         * medor
         * ara
         */

        Arrays.sort(dogs, Dog.NameComparator);
        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * ara
         * medor
         * brutus
         */

    }
}

Here is a good example how to use comparable in Java:

http://www.onjava.com/pub/a/onjava/2003/03/12/java_comp.html?page=2

window.onload = () => {
  // run in onload
  setTimeout(() => {
    // onload finished.
    // and execute some code here like stat performance.
  }, 10)
}

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);
}

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

If you bind the event through mootools' addEvent function your event handler will get a fixed (augmented) event passed as the parameter. It will always contain the preventDefault() method.

Try out this fiddle to see the difference in event binding. http://jsfiddle.net/pFqrY/8/

// preventDefault always works
$("mootoolsbutton").addEvent('click', function(event) {
 alert(typeof(event.preventDefault));
});

// preventDefault missing in IE
<button
  id="htmlbutton"
  onclick="alert(typeof(event.preventDefault));">
  button</button>

For all jQuery users out there you can fix an event when needed. Say that you used HTML onclick=".." and get a IE specific event that lacks preventDefault(), just use this code to get it.

e = $.event.fix(e);

After that e.preventDefault(); works fine.

You can use inline styling to limit the height:

<img src="" class="img-responsive" alt="" style="max-height: 400px;">

 1. How can I completely avoid reverse engineering of an Android APK? Is this possible?

This isn't possible

 2. How can I protect all the app's resources, assets and source code so that hackers can't hack the APK file in any way?

When somebody change a .apk extension to .zip, then after unzipping, someone can easily get all resources (except Manifest.xml), but with APKtool one can get the real content of the manifest file too. Again, a no.

 3. Is there a way to make hacking more tough or even impossible? What more can I do to protect the source code in my APK file?

Again, no, but you can prevent upto some level, that is,

• Download a resource from the Web and do some encryption process
• Use a pre-compiled native library (C, C++, JNI, NDK)
• Always perform some hashing (MD5/SHA keys or any other logic)

Even with Smali, people can play with your code. All in all, it's not POSSIBLE.

grep -rl $oldstring . | xargs sed -i "s/$oldstring/$newstring/g"

booleanExpression ? trueValue : falseValue;

Example:

string itemText = count > 1 ? "items" : "item";

http://zamirsblog.blogspot.com/2011/12/c-vb-equivalent-of-iif.html

We can use ng-src but when ng-src's value became null, '' or undefined, ng-src will not work. So just use ng-if for this case:

http://jsfiddle.net/Hx7B9/299/

<div ng-app>
    <div ng-controller="AppCtrl"> 
        <a href='#'><img ng-src="{{link}}" ng-if="!!link"/></a>
        <button ng-click="changeLink()">Change Image</button>
    </div>
</div>

I got the solution:

import nltk
nltk.download()

once the NLTK Downloader starts

d) Download l) List u) Update c) Config h) Help q) Quit

Downloader> d

Download which package (l=list; x=cancel)? Identifier> punkt

Your regular expression should be \btrue\b to get around the 'miscontrue' issue Casper brings up. The full solution would look like this:

string searchText = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
string regexPattern = @"\btrue\b";
int numberOfTrues = Regex.Matches(searchText, regexPattern).Count;

Make sure the System.Text.RegularExpressions namespace is included at the top of the file.

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

You can use canvas’ context.translate & context.rotate to do rotate your image

Here’s a function to draw an image that is rotated by the specified degrees:

function drawRotated(degrees){
    context.clearRect(0,0,canvas.width,canvas.height);

    // save the unrotated context of the canvas so we can restore it later
    // the alternative is to untranslate & unrotate after drawing
    context.save();

    // move to the center of the canvas
    context.translate(canvas.width/2,canvas.height/2);

    // rotate the canvas to the specified degrees
    context.rotate(degrees*Math.PI/180);

    // draw the image
    // since the context is rotated, the image will be rotated also
    context.drawImage(image,-image.width/2,-image.width/2);

    // we’re done with the rotating so restore the unrotated context
    context.restore();
}

As a follow-up to my own comment: Trove looks like the way to go. If, for whatever reason, you wanted to stick with the standard JDK, ConcurrentMap and AtomicLong can make the code a tiny bit nicer, though YMMV.

    final ConcurrentMap<String, AtomicLong> map = new ConcurrentHashMap<String, AtomicLong>();
    map.putIfAbsent("foo", new AtomicLong(0));
    map.get("foo").incrementAndGet();

will leave 1 as the value in the map for foo. Realistically, increased friendliness to threading is all that this approach has to recommend it.

Polymorphism is when you can treat an object as a generic version of something, but when you access it, the code determines which exact type it is and calls the associated code.

Here is an example in C#. Create four classes within a console application:

public abstract class Vehicle
{
    public abstract int Wheels;
}

public class Bicycle : Vehicle
{
    public override int Wheels()
    {
        return 2;
    }
}

public class Car : Vehicle
{
    public override int Wheels()
    {
        return 4;
    }
}

public class Truck : Vehicle
{
    public override int Wheels()
    {
        return 18;
    }
}

Now create the following in the Main() of the module for the console application:

public void Main()
{
    List<Vehicle> vehicles = new List<Vehicle>();

    vehicles.Add(new Bicycle());
    vehicles.Add(new Car());
    vehicles.Add(new Truck());

    foreach (Vehicle v in vehicles)
    {
        Console.WriteLine(
            string.Format("A {0} has {1} wheels.",
                v.GetType().Name, v.Wheels));
    }
}

In this example, we create a list of the base class Vehicle, which does not know about how many wheels each of its sub-classes has, but does know that each sub-class is responsible for knowing how many wheels it has.

We then add a Bicycle, Car and Truck to the list.

Next, we can loop through each Vehicle in the list, and treat them all identically, however when we access each Vehicles 'Wheels' property, the Vehicle class delegates the execution of that code to the relevant sub-class.

This code is said to be polymorphic, as the exact code which is executed is determined by the sub-class being referenced at runtime.

I hope that this helps you.

Try this

window['marker'+i] = "some stuff"; 

Just add a new datafile for the existing tablespace

ALTER TABLESPACE LEGAL_DATA ADD DATAFILE '/u01/oradata/userdata03.dbf' SIZE 200M;

To find out the location and size of your data files:

SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'LEGAL_DATA';

The first time you run the page, the query_age index doesn't exist because it hasn't been sent over from the form.

When you submit the form it will then exist, and it won't complain about it.

#so change
$_GET['query_age'];
#to:
(!empty($_GET['query_age']) ? $_GET['query_age'] : null);

In addition to @millimoose's answer, setters can also be used to update other values.

function Name(first, last) {
    this.first = first;
    this.last = last;
}

Name.prototype = {
    get fullName() {
        return this.first + " " + this.last;
    },

    set fullName(name) {
        var names = name.split(" ");
        this.first = names[0];
        this.last = names[1];
    }
};

Now, you can set fullName, and first and last will be updated and vice versa.

n = new Name('Claude', 'Monet')
n.first # "Claude"
n.last # "Monet"
n.fullName # "Claude Monet"
n.fullName = "Gustav Klimt"
n.first # "Gustav"
n.last # "Klimt"

Use below code to get all attributes with details

    global $wpdb;

    $attribute_taxonomies = $wpdb->get_results( "SELECT * FROM " . $wpdb->prefix . "woocommerce_attribute_taxonomies WHERE attribute_name != '' ORDER BY attribute_name ASC;" );
    set_transient( 'wc_attribute_taxonomies', $attribute_taxonomies );

    $attribute_taxonomies = array_filter( $attribute_taxonomies  ) ;

    prin_r($attribute_taxonomies);

Use docker start <your_container_name>

Then connect to database by using mssql -u <yourUsername> -p <yourPassword>

If you get an error in the first step then the docker is running and go with the second step.

Note: I use Mac as my primary OS and this might be the same answer for Unix based OSs. If not! Sorry in advance.

If Apache was installed using NSIS installer it should have left an uninstaller. You should search inside Apache installation directory for executable named unistaller.exe or something like that. NSIS uninstallers support /S flag by default for silent uninstall. So you can run something like "C:\Program Files\<Apache installation dir here>\uninstaller.exe" /S

From NSIS documentation:

3.2.1 Common Options

/NCRC disables the CRC check, unless CRCCheck force was used in the script. /S runs the installer or uninstaller silently. See section 4.12 for more information. /D sets the default installation directory ($INSTDIR), overriding InstallDir and InstallDirRegKey. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.

DateFormatter has some factory date styles for those too lazy to tinker with formatting strings. If you don't need a custom style, here's another option:

extension Date {  
  func asString(style: DateFormatter.Style) -> String {
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = style
    return dateFormatter.string(from: self)
  }
}

This gives you the following styles:

short, medium, long, full

Example usage:

let myDate = Date()
myDate.asString(style: .full)   // Wednesday, January 10, 2018
myDate.asString(style: .long)   // January 10, 2018
myDate.asString(style: .medium) // Jan 10, 2018
myDate.asString(style: .short)  // 1/10/18

I have been trying all the answers here with no success. Here is the simplest way to do it with ms-appx

        ImageBrush myBrush = new ImageBrush();
        Image image = new Image();
        image.Source = new BitmapImage(new Uri(@"ms-appx:///Assets/background.jpg"));
        myBrush.ImageSource = image.Source;
        TheGrid.Background = myBrush;

Assets folder is in the first level of my project, so make sure to change the path as convenient.

Please add below jQuery Migrate Plugin

To iterate over each file a for loop will work:

for %%f in (directory\path\*) do ( something_here )

In my case I also wanted the file content, name, etc.

This lead to a few issues and I thought my use case might help. Here is a loop that reads info from each '.txt' file in a directory and allows you do do something with it (setx for instance).

@ECHO OFF
setlocal enabledelayedexpansion
for %%f in (directory\path\*.txt) do (
  set /p val=<%%f
  echo "fullname: %%f"
  echo "name: %%~nf"
  echo "contents: !val!"
)

*Limitation: val<=%%f will only get the first line of the file.

Close... try:

select 
   Sum(case when rsp_ind = 0 then 1 Else 0 End) as 'New',
   Sum(case when rsp_ind = 1 then 1 else 0 end) as 'Accepted'

You have most of the code…

CURLOPT_HTTPHEADER for curl_setopt() takes an array with each header as an element. You have one element with multiple headers.

You also need to add the Authorization header to your $header array.

$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: OAuth SomeHugeOAuthaccess_tokenThatIReceivedAsAString';

/(\w*\(Hex\): w*)(.*?)(?= |$)/gm

I'm sure this one works, it will capture de hexa serial in the badly structured text multilined bellow

     Space Reservation: disabled
         Serial Number: wCVt1]IlvQWv
   Serial Number (Hex): 77435674315d496c76515776
               Comment: new comment

I'm a eternal newbie in regex but I'll try explain this one

(\w*(Hex): w*) : Find text in line where string contains "Hex: "

(.*?) This is the second captured text and means everything after

(?= |$) create a limit that is the space between = and the |

So with the second group, you will have the value

>>> a=$("#communitymode")[0]
<input id="communitymode" type="checkbox" name="communitymode">
>>> a.type
"checkbox"

Or, more of the style of jQuery:

$("#myinput").attr('type') == 'checkbox'

As to std::vector<int> vec, vec to get int*, you can use two method:

1. int* arr = &vec[0];

2. int* arr = vec.data();

If you want to convert any type T vector to T* array, just replace the above int to T.

I will show you why does the above two works, for good understanding?

std::vector is a dynamic array essentially.

Main data member as below:

template <class T, class Alloc = allocator<T>>
class vector{
    public:
        typedef T          value_type;
        typedef T*         iterator;
        typedef T*         pointer;
        //.......
    private:
        pointer start_;
        pointer finish_;
        pointer end_of_storage_;

    public:
        vector():start_(0), finish_(0), end_of_storage_(0){}
    //......
}

The range (start_, end_of_storage_) is all the array memory the vector allocate;

The range(start_, finish_) is all the array memory the vector used;

The range(finish_, end_of_storage_) is the backup array memory.

For example, as to a vector vec. which has {9, 9, 1, 2, 3, 4} is pointer may like the below.

So &vec[0] = start_ (address.) (start_ is equivalent to int* array head)

In c++11 the data() member function just return start_

pointer data()
{ 
     return start_; //(equivalent to `value_type*`, array head)
}

There is no native version of Visual Studio for Mac OS X.

Almost all versions of Visual Studio have a Garbage rating on Wine's application database, so Wine isn't an option either, sadly.

Try $_SERVER['SERVER_NAME'].

Tips: Create a PHP file that calls the function phpinfo() and see the "PHP Variables" section. There are a bunch of useful variables we never think of there.

If you like the method in the link you've posted, have a look at Git Flow.

It's a set of scripts he created for that workflow.

But to answer your question:

$ git checkout -b myFeature dev

Creates MyFeature branch off dev. Do your work and then

$ git commit -am "Your message"

Now merge your changes to dev without a fast-forward

$ git checkout dev
$ git merge --no-ff myFeature

Now push changes to the server

$ git push origin dev
$ git push origin myFeature

And you'll see it how you want it.

Use import scala.collection.mutable.MutableList or similar if you really need mutation.

import scala.collection.mutable.MutableList
val x = MutableList(1, 2, 3, 4, 5)
x += 6 // MutableList(1, 2, 3, 4, 5, 6)
x ++= MutableList(7, 8, 9) // MutableList(1, 2, 3, 4, 5, 6, 7, 8, 9)

One major difference between Sequelize and Persistence.js is that the former supports a STRING datatype, i.e. VARCHAR(255). I felt really uncomfortable making everything TEXT.

I submit that it is better to leave your data stacked as it is:

df = pandas.DataFrame(data, columns=['R_Number', 'C_Number', 'Avg', 'Std'])

# Possibly also this if these can always be the indexes:
# df = df.set_index(['R_Number', 'C_Number'])

Then it's a bit more intuitive to say

df.set_index(['R_Number', 'C_Number']).Avg.unstack(level=1)

This way it is implicit that you're seeking to reshape the averages, or the standard deviations. Whereas, just using pivot, it's purely based on column convention as to what semantic entity it is that you are reshaping.

You could use the String Convert.ToBase64String(byte[]) to encode the byte array into a base64 string, then Byte[] Convert.FromBase64String(string) to convert the resulting string back into a byte array.

Just delete the ${user.home}/.m2/repository/org/apache/maven/archetypes to refresh all files needed, it worked fine to me!

)

I found same question or related question on stackoverflow

Is there any way to change input type=“date” format?

I found one simple solution, You can not give particulate Format but you can customize Like this.

HTML Code:

    <body>
<input type="date" id="dt" onchange="mydate1();" hidden/>
<input type="text" id="ndt"  onclick="mydate();" hidden />
<input type="button" Value="Date" onclick="mydate();" />
</body>

CSS Code:

#dt{text-indent: -500px;height:25px; width:200px;}

Javascript Code :

function mydate()
{
  //alert("");
document.getElementById("dt").hidden=false;
document.getElementById("ndt").hidden=true;
}
function mydate1()
{
 d=new Date(document.getElementById("dt").value);
dt=d.getDate();
mn=d.getMonth();
mn++;
yy=d.getFullYear();
document.getElementById("ndt").value=dt+"/"+mn+"/"+yy
document.getElementById("ndt").hidden=false;
document.getElementById("dt").hidden=true;
}

Output:

$request = new \Zend\Http\PhpEnvironment\Request();
$httpMethod = $request->getMethod();

In this way you can also achieve in zend framework 2 also. Thanks.

The javadocs for Scanner answer your question

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.

You might change the default whitespace pattern the Scanner is using by doing something like

Scanner s = new Scanner();
s.useDelimiter("\n");

When using the LESS version you can import mixins.less and create your own classes for colored badges:

.badge-warning {
    .label-variant(@label-warning-bg);
}

Same for the other colors; just replace warning with danger, success, etc.

Here you go. this should work.

questionFrame.frame = CGRectMake(0 , 0, self.view.frame.width, self.view.frame.height * 0.7) 

answerFrame.frame =  CGRectMake(0 , self.view.frame.height * 0.7, self.view.frame.width, self.view.frame.height * 0.3)

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.

pass the output to str() function and it will remove the convert the unicode output. also by printing the output it will remove the u'' tags from it.

Beware that in Mysql, the utf8 character set is only a subset of the real UTF8 character set. In order to save one byte of storage, the Mysql team decided to store only three bytes of a UTF8 characters instead of the full four-bytes. That means that some east asian language and emoji aren't fully supported. To make sure you can store all UTF8 characters, use the utf8mb4 data type, and utf8mb4_bin or utf8mb4_general_ci in Mysql.

I love extension methods and this is the one I use...

static class StringHelpers
{
    public static bool ToBoolean(this String input, out bool output)
    {
        //Set the default return value
        output = false;

        //Account for a string that does not need to be processed
        if (input == null || input.Length < 1)
            return false;

        if ((input.Trim().ToLower() == "true") || (input.Trim() == "1"))
            output = true;
        else if ((input.Trim().ToLower() == "false") || (input.Trim() == "0"))
            output = false;
        else
            return false;

        //Return success
        return true;
    }
}

Then to use it just do something like...

bool b;
bool myValue;
data = "1";
if (!data.ToBoolean(out b))
  throw new InvalidCastException("Could not cast to bool value from data '" + data + "'.");
else
  myValue = b;  //myValue is True

filter(lambda v: v==v, x)

works both for lists and numpy array since v!=v only for NaN

I noticed some issues with this that might be useful for someone just starting, or a somewhat inexperienced user, to know. First...

CD /D "C:\Documents and Settings\%username%\Start Menu\Programs\"

two things one is that a /D after the CD may prove to be useful in making sure the directory is changed but it's not really necessary, second, if you are going to pass this from user to user you have to add, instead of your name, the code %username%, this makes the code usable on any computer, as long as they have your setup.exe file in the same location as you do on your computer. of course making sure of that is more difficult. also...

start \\filer\repo\lab\"software"\"myapp"\setup.exe

the start code here, can be set up like that, but the correct syntax is

start "\\filter\repo\lab\software\myapp\" setup.exe

This will run: setup.exe, located in: \filter\repo\lab...etc.\

at version 4.0 or above, we need to create one 'config.inc.php' or rename the 'config.sample.inc.php' to 'config.inc.php';

In my case, I also work with one mysql server for each environment (dev and production):

/* others code*/  
$whoIam = gethostname();
switch($whoIam) {
    case 'devHost':
        $cfg['Servers'][$i]['host'] = 'localhost';
        break;
    case 'MasterServer':
        $cfg['Servers'][$i]['host'] = 'masterMysqlServer';
        break;
} /* others code*/ 

The program is printing "Hey this is my first hello world ", then it is moving the cursor back to the beginning of the line. How this will look on the screen depends on your environment. It appears the beginning of the string is being overwritten by something, perhaps your command line prompt.

$ mvn --version

and look for Maven home: in the output , mine is: Maven home: /usr/share/maven

I've just found this solution:

if(@getimagesize($remoteImageURL)){
    //image exists!
}else{
    //image does not exist.
}

Source: http://www.dreamincode.net/forums/topic/11197-checking-if-file-exists-on-remote-server/

Try running,

SELECT SERVERPROPERTY('COLLATION')

Then find out if your collation is case sensitive or not.

I made a simple tool that will display an image given a filename or image object or url.
It's crude, but it'll do in a hurry.

Installation:

 $ pip install simple-imshow

Usage:

from simshow import simshow
simshow('some_local_file.jpg')  # display from local file
simshow('http://mathandy.com/escher_sphere.png')  # display from url

Another approach would be like this:

temp = df['Seatblocks'].str.split(' ')
data = data.reindex(data.index.repeat(temp.apply(len)))
data['new_Seatblocks'] = np.hstack(temp)

Oracle support Mathematical Subtract - operator on Data datatype. You may directly put in select clause following statement:

to_char (s.last_upd – s.created, ‘999999D99')

Check the EXAMPLE for more visibility.

In case you need the output in termes of hours, then the below might help;

Select to_number(substr(numtodsinterval([END_TIME]-[START_TIME]),’day’,2,9))*24 +
to_number(substr(numtodsinterval([END_TIME]-[START_TIME],’day’),12,2))
||':’||to_number(substr(numtodsinterval([END_TIME]-[START_TIME],’day’),15,2)) 
from [TABLE_NAME];

How to use a clock and do assertions

This example shows how to generate a clock, and give inputs and assert outputs for every cycle. A simple counter is tested here.

The key idea is that the process blocks run in parallel, so the clock is generated in parallel with the inputs and assertions.

library ieee;
use ieee.std_logic_1164.all;

entity counter_tb is
end counter_tb;

architecture behav of counter_tb is
    constant width : natural := 2;
    constant clk_period : time := 1 ns;

    signal clk : std_logic := '0';
    signal data : std_logic_vector(width-1 downto 0);
    signal count : std_logic_vector(width-1 downto 0);

    type io_t is record
        load : std_logic;
        data : std_logic_vector(width-1 downto 0);
        count : std_logic_vector(width-1 downto 0);
    end record;
    type ios_t is array (natural range <>) of io_t;
    constant ios : ios_t := (
        ('1', "00", "00"),
        ('0', "UU", "01"),
        ('0', "UU", "10"),
        ('0', "UU", "11"),

        ('1', "10", "10"),
        ('0', "UU", "11"),
        ('0', "UU", "00"),
        ('0', "UU", "01")
    );
begin
    counter_0: entity work.counter port map (clk, load, data, count);

    process
    begin
        for i in ios'range loop
            load <= ios(i).load;
            data <= ios(i).data;
            wait until falling_edge(clk);
            assert count = ios(i).count;
        end loop;
        wait;
    end process;

    process
    begin
        for i in 1 to 2 * ios'length loop
            wait for clk_period / 2;
            clk <= not clk;
        end loop;
        wait;
    end process;
end behav;

The counter would look like this:

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all; -- unsigned

entity counter is
    generic (
        width : in natural := 2
    );
    port (
        clk, load : in std_logic;
        data : in std_logic_vector(width-1 downto 0);
        count : out std_logic_vector(width-1 downto 0)
    );
end entity counter;

architecture rtl of counter is
    signal cnt : unsigned(width-1 downto 0);
begin
    process(clk) is
    begin
        if rising_edge(clk) then
            if load = '1' then
                cnt <= unsigned(data);
            else
                cnt <= cnt + 1;
            end if;
        end if;
    end process;
    count <= std_logic_vector(cnt);
end architecture rtl;

You can get clean and clear solutions by building the appropriate predicates as helper functions. In other words, use the Python set-builder notation the same way you would write the answer with regular mathematics set-notation.

The whole idea behind set comprehensions is to let us write and reason in code the same way we do mathematics by hand.

With an appropriate predicate in hand, problem 1 simplifies to:

 low_primes = {x for x in range(1, 100) if is_prime(x)}

And problem 2 simplifies to:

 low_prime_pairs = {(x, x+2) for x in range(1,100,2) if is_prime(x) and is_prime(x+2)}

Note how this code is a direct translation of the problem specification, "A Prime Pair is a pair of consecutive odd numbers that are both prime."

P.S. I'm trying to give you the correct problem solving technique without actually giving away the answer to the homework problem.

you can use implicit casting AddWithValue

cmd.Parameters.AddWithValue("@param1", klantId);
cmd.Parameters.AddWithValue("@param2", klantNaam);
cmd.Parameters.AddWithValue("@param3", klantVoornaam);

sample code,

using (SqlConnection conn = new SqlConnection("connectionString")) 
{
    using (SqlCommand cmd = new SqlCommand()) 
    { 
        cmd.Connection = conn;
        cmd.CommandType = CommandType.Text;
        cmd.CommandText = @"INSERT INTO klant(klant_id,naam,voornaam) 
                            VALUES(@param1,@param2,@param3)";  

        cmd.Parameters.AddWithValue("@param1", klantId);  
        cmd.Parameters.AddWithValue("@param2", klantNaam);  
        cmd.Parameters.AddWithValue("@param3", klantVoornaam);  

        try
        {
            conn.Open();
            cmd.ExecuteNonQuery(); 
        }
        catch(SqlException e)
        {
            MessgeBox.Show(e.Message.ToString(), "Error Message");
        }

    } 
}

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

As explained in the documentation, by using an @RequestParam annotation:

public @ResponseBody String byParameter(@RequestParam("foo") String foo) {
    return "Mapped by path + method + presence of query parameter! (MappingController) - foo = "
           + foo;
}

I would generally try to avoid the use of #pragmas if possible, since they're extremely compiler-dependent and non-portable. If you want to use them in a portable fashion, you'll have to surround every pragma with a #if/#endif pair. GCC discourages the use of pragmas, and really only supports some of them for compatibility with other compilers; GCC has other ways of doing the same things that other compilers use pragmas for.

For example, here's how you'd ensure that a structure is packed tightly (i.e. no padding between members) in MSVC:

#pragma pack(push, 1)
struct PackedStructure
{
  char a;
  int b;
  short c;
};
#pragma pack(pop)
// sizeof(PackedStructure) == 7

Here's how you'd do the same thing in GCC:

struct PackedStructure __attribute__((__packed__))
{
  char a;
  int b;
  short c;
};
// sizeof(PackedStructure == 7)

The GCC code is more portable, because if you want to compile that with a non-GCC compiler, all you have to do is

#define __attribute__(x)

Whereas if you want to port the MSVC code, you have to surround each pragma with a #if/#endif pair. Not pretty.

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

pip is not give permission so can't do pip install.Try below command.

apt-get install python-virtualenv

I think you are using 'global' incorrectly. See Python reference. You should declare variable without global and then inside the function when you want to access global variable you declare it global yourvar.

#!/usr/bin/python

total

def checkTotal():
    global total
    total = 0

See this example:

#!/usr/bin/env python

total = 0

def doA():
    # not accessing global total
    total = 10

def doB():
    global total
    total = total + 1

def checkTotal():
    # global total - not required as global is required
    # only for assignment - thanks for comment Greg
    print total

def main():
    doA()
    doB()
    checkTotal()

if __name__ == '__main__':
    main()

Because doA() does not modify the global total the output is 1 not 11.

seems if %% followed with a %@, the NSString will go to some strange codes try this and this worked for me

NSString *str = [NSString stringWithFormat:@"%@%@%@", @"%%", 
                 [textfield text], @"%%"]; 

You can use a space followed by the grave accent (backtick):

Get-ChildItem -Recurse `
  -Filter *.jpg `
  | Select LastWriteTime

However, this is only ever necessary in such cases as shown above. Usually you get automatic line continuation when a command cannot syntactically be complete at that point. This includes starting a new pipeline element:

Get-ChildItem |
  Select Name,Length

will work without problems since after the | the command cannot be complete since it's missing another pipeline element. Also opening curly braces or any other kind of parentheses will allow line continuation directly:

$x=1..5
$x[
  0,3
] | % {
  "Number: $_"
}

Similar to the | a comma will also work in some contexts:

1,
2

Keep in mind, though, similar to JavaScript's Automatic Semicolon Insertion, there are some things that are similarly broken because the line break occurs at a point where it is preceded by a valid statement:

return
  5

will not work.

Finally, strings (in all varieties) may also extend beyond a single line:

'Foo
bar'

They include the line breaks within the string, then.

If you are absolutely sure that libncurses, aka ncurses, is installed, as in you've done a successful 'ls' of the library, then perhaps you are running a 64 bit Linux operating system and only have the 64 bit libncurses installed, when the program that is running (adb) is 32 bit.

If so, a 32 bit program can't link to a 64 bit library (and won't located it anyway), so you might have to install libcurses, or ncurses (32 bit version). Likewise, if you are running a 64 bit adb, perhaps your ncurses is 32 bit (a possible but less likely scenario).

Try this.

1.write a custom filter

    package com.dtd.util;

    import javax.servlet.*;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;

    public class CORSFilter implements Filter {

        @Override
        public void init(FilterConfig filterConfig) throws ServletException {

        }

        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;
            httpResponse.addHeader("Access-Control-Allow-Origin", "*");
            filterChain.doFilter(servletRequest, servletResponse);
        }

        @Override
        public void destroy() {

        }
    }

2.add to web.xml

<filter>
    <filter-name>CorsFilter</filter-name>
    <filter-class>com.dtd.util.CORSFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>CorsFilter</filter-name>

Use the matplotlib savefig function with the keyword argument transparent=True to save the image as a png file.

In [30]: x = np.linspace(0,6,31)

In [31]: y = np.exp(-0.5*x) * np.sin(x)

In [32]: plot(x, y, 'bo-')
Out[32]: [<matplotlib.lines.Line2D at 0x3f29750>]            

In [33]: savefig('demo.png', transparent=True)

Result:

Of course, that plot doesn't demonstrate the transparency. Here's a screenshot of the PNG file displayed using the ImageMagick display command. The checkerboard pattern is the background that is visible through the transparent parts of the PNG file.

You should really use a set based solution involving two queries (basic insert):

INSERT INTO TableB (Id2Column, Column33, Column44)
SELECT id, column1, column2 FROM TableA

UPDATE TableA SET column1 = column2 * column3

And for your transform:

INSERT INTO TableB (Id2Column, Column33, Column44)
SELECT 
    id, 
    column1 * column4 * 100, 
    (column2 / column12) 
FROM TableA

UPDATE TableA SET column1 = column2 * column3

Now if your transform is more complicated than that and involved multiple tables, post another question with the details.

Try to delete the temp files

cd /tmp/
rm -r *

Instead of using a submit button, try using a <button type="button">Submit</button>

You can then call a javascript function in the button, and after the alert popup is confirmed, you can manually submit the form with document.getElementById("form").submit(); ... so you'll need to name and id your form for that to work.

You can use color code also.

 const marker: Marker = this.map.addMarkerSync({
    icon: '#008000',
    animation: 'DROP',
    position: {lat: 39.0492127, lng: -111.1435662},
    map: this.map,
 });

This is because of ng-include which creates a new child scope, so $scope.lineText isn’t changed. I think that this refers to the current scope, so this.lineText should be set.

I just had to do this myself, you need to do it the other way around.

• do not play with the vertical-align of your text
• play with the vertical align of the font-awesome icon

<div>
  <span class="icon icon-2x icon-camera" style=" vertical-align: middle;"></span>
  <span class="my-text">hello world</span>
</div>

Of course you could not use inline styles and target it with your own css class. But this works in a copy paste fashion.

See here: Vertical alignment of text and icon in button

If it were up to me however, I would not use the icon-2x. And simply specify the font-size myself, as in the following

<div class='my-fancy-container'>
    <span class='my-icon icon-file-text'></span>
    <span class='my-text'>Hello World</span>
</div>

.my-icon {
    vertical-align: middle;
    font-size: 40px;
}

.my-text {
    font-family: "Courier-new";
}

.my-fancy-container {
    border: 1px solid #ccc;
    border-radius: 6px;
    display: inline-block;
    margin: 60px;
    padding: 10px;
}

for a working example, please see JsFiddle

request.raw_response is now deprecated. Use request.body instead to process non-conventional form data such as XML payloads, binary images, etc.

Here is a very easy way of doing that

 $(function () {
    $(".glyphicon").unbind('click');
    $(".glyphicon").click(function (e) {
        $(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");
});

Hope this helps :D

Here is the answer if you want to put image with fixed percentage of width, but not fixed pixel of width.

And this will be useful when dealing with different size of screen.

The tricks are

1. Using padding-top to set the height from width.
2. Using position: absolute to put image in the padding space.
3. Using max-height and max-width to make sure the image will not over the parent element.
4. using display:block and margin: auto to center the image.

I've also comment most of the tricks inside the fiddle.

I also find some other ways to make this happen. There will be no real image in html, so I personly perfer the top answer when I need "img" element in html.

simple css by using background http://jsfiddle.net/4660s79h/2/

background-image with word on top http://jsfiddle.net/4660s79h/1/

the concept to use position absolute is from here http://www.w3schools.com/howto/howto_css_aspect_ratio.asp

This code checks if the number is odd or even in PHP. In the example $a is 2 and you get even number. If you need odd then change the $a value

$a=2;
if($a %2 == 0){
    echo "<h3>This Number is <b>$a</b> Even</h3>";
}else{
    echo "<h3>This Number is <b>$a</b> Odd</h3>";
}

Supplier with a one-to-many relationship with Product. One Supplier has (supplies) many Products.

Factors:

• Lazy mode for Supplier set to “true” (default)

• Fetch mode used for querying on Product is Select

• Fetch mode (default): Supplier information is accessed

• Caching does not play a role for the first time the

• Supplier is accessed

Fetch mode is Select Fetch (default)

// It takes Select fetch mode as a default
Query query = session.createQuery( "from Product p");
List list = query.list();
// Supplier is being accessed
displayProductsListWithSupplierName(results);

Result:

• 1 select statement for Product
• N select statements for Supplier

This is N+1 select problem!

A li doesn't have a value. Only form-related elements such as input, textarea and select have values.

On my Windows 7 machine I have the following environment variables:

• JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07

• M2_HOME=C:\apache-maven-3.0.3

On my PATH variable, I have (among others) the following:

• %JAVA_HOME%\bin;%M2_HOME%\bin

I tried doing what you've done with %M2% having the nested %M2_HOME% and it also works.

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

Try this :

$obj = @{
    SomeProp = "Hello"
}

Write-Host "Property Value is $($obj."SomeProp")"

if you tried the solutions above and didin't solve the problem, it can be because of version inconsistency.

I installed python 3.9 and i couldn't install tensorflow with pip.

And then I uninstalled 3.9, then installed 3.8.7 and success... the max version that tensorflow is supported by is 3.8.x (in 2021) so, check your python version is compatible or not with current tensorflow.

below is an generic example

    //base class
    class A {
        
        // The virtual method
        protected virtualStuff1?():void;
    
        public Stuff2(){
            //Calling overridden child method by parent if implemented
            this.virtualStuff1 && this.virtualStuff1();
            alert("Baseclass Stuff2");
        }
    }
    
    //class B implementing virtual method
    class B extends A{
        
        // overriding virtual method
        public virtualStuff1()
        {
            alert("Class B virtualStuff1");
        }
    }
    
    //Class C not implementing virtual method
    class C extends A{
     
    }
    
    var b1 = new B();
    var c1= new C();
    b1.Stuff2();
    b1.virtualStuff1();
    c1.Stuff2();

The xor operator is ^

For example: SELECT A ^ B where A and B are integer category data types.

Query syntax:

var count = (from o in context.MyContainer
             where o.ID == '1'
             from t in o.MyTable
             select t).Count();

Method syntax:

var count = context.MyContainer
            .Where(o => o.ID == '1')
            .SelectMany(o => o.MyTable)
            .Count()

Both generate the same SQL query.

With the useEffect hook it's possible to detect route changes without adding a listener.

import React, { useEffect }           from 'react';
import { Switch, Route, withRouter }  from 'react-router-dom';
import Main                           from './Main';
import Blog                           from './Blog';


const App  = ({history}) => {

    useEffect( () => {

        // When route changes, history.location.pathname changes as well
        // And the code will execute after this line

    }, [history.location.pathname]);

    return (<Switch>
              <Route exact path = '/'     component = {Main}/>
              <Route exact path = '/blog' component = {Blog}/>
            </Switch>);

}

export default withRouter(App);

You can remove public keyword from your functions, because, you have to define a class in order to declare public, private or protected function

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.

Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.

I'd like to provide an alternate solution, a robust solution similar to what I am about to propose was required in the latest version of ggtern, since introducing the canvas rotation feature.

Basically, you need to determine the relative positions using trigonometry, by building a function which returns an element_text object, given angle (ie degrees) and positioning (ie one of x,y,top or right) information.

#Load Required Libraries
library(ggplot2)
library(gridExtra)

#Build Function to Return Element Text Object
rotatedAxisElementText = function(angle,position='x'){
  angle     = angle[1]; 
  position  = position[1]
  positions = list(x=0,y=90,top=180,right=270)
  if(!position %in% names(positions))
    stop(sprintf("'position' must be one of [%s]",paste(names(positions),collapse=", ")),call.=FALSE)
  if(!is.numeric(angle))
    stop("'angle' must be numeric",call.=FALSE)
  rads  = (angle - positions[[ position ]])*pi/180
  hjust = 0.5*(1 - sin(rads))
  vjust = 0.5*(1 + cos(rads))
  element_text(angle=angle,vjust=vjust,hjust=hjust)
}

Frankly, in my opinion, I think that an 'auto' option should be made available in ggplot2 for the hjust and vjust arguments, when specifying the angle, anyway, lets demonstrate how the above works.

#Demonstrate Usage for a Variety of Rotations
df    = data.frame(x=0.5,y=0.5)
plots = lapply(seq(0,90,length.out=4),function(a){
  ggplot(df,aes(x,y)) + 
    geom_point() + 
    theme(axis.text.x = rotatedAxisElementText(a,'x'),
          axis.text.y = rotatedAxisElementText(a,'y')) +
    labs(title = sprintf("Rotated %s",a))
})
grid.arrange(grobs=plots)

Which produces the following:

Regarding the original question asked in the title ...

• sudo apt-get install libtcnative-1

• or if you are on RHEL Linux yum install tomcat-native

The documentation states you need http://tomcat.apache.org/native-doc/

• sudo apt-get install libapr1.0-dev libssl-dev
• or RHEL yum install apr-devel openssl-devel

You could create your own .xml animation files to fade in a new Activity and fade out the current Activity:

fade_in.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
           android:interpolator="@android:anim/accelerate_interpolator"
           android:fromAlpha="0.0" android:toAlpha="1.0"
           android:duration="500" />

fade_out.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
           android:interpolator="@android:anim/accelerate_interpolator"
           android:fromAlpha="1.0" android:toAlpha="0.0"
           android:fillAfter="true"
           android:duration="500" />

Use it in code like that: (Inside your Activity)

Intent i = new Intent(this, NewlyStartedActivity.class);
startActivity(i);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);

The above code will fade out the currently active Activity and fade in the newly started Activity resulting in a smooth transition.

UPDATE: @Dan J pointed out that using the built in Android animations improves performance, which I indeed found to be the case after doing some testing. If you prefer working with the built in animations, use:

overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

Notice me referencing android.R instead of R to access the resource id.

UPDATE: It is now common practice to perform transitions using the Transition class introduced in API level 19.

You can use .text-reset class to reset the color from default blue to anything you want. Hopefully this is helpful.

I experienced this error when trying to embed an iframe and then opening the site with Brave. The error went away when I changed to "Shields Down" for the site in question. Obviously, this is not a full solution, since anyone else visiting the site with Brave will run into the same issue. To actually resolve it I would need to do one of the other things listed on this page. But at least I now know where the problem lies.

You can do :

document.forms["loginForm"].submit()

But this won't call the onclick action of your button, so you will need to call it by hand.

Be aware that you must use the name of your form and not the id to access it.

target="_blank" attribute will do the job. Just don't forget to add rel="noopener noreferrer" to solve the potential vulnerability. More on that here: https://dev.to/ben/the-targetblank-vulnerability-by-example

<a href="https://www.google.com/" target="_blank" rel="noopener noreferrer">Searcher</a>

You can add following in wp-config.php

define('METHOD','direct');

It appears that SQL Server 2008 R2 can be downloaded with or without the management tools. I honestly have NO IDEA why someone would not want the management tools. But either way, the options are here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

and the one for 64 bit WITH the management tools (management studio) is here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

From the first link I presented, the 3rd and 4th include the management studio for 32 and 64 bit respectively.

Python's string interpolation is similar to C's printf()

If you try:

name = "SpongeBob Squarepants"
print "Who lives in a Pineapple under the sea? %s" % name

The tag %s will be replaced with the name variable. You should take a look to the print function tags: http://docs.python.org/library/functions.html

You need add masksToBounds = true for combined between corderRadius shadowRadius.

button.layer.masksToBounds = false;

minHeight = Math.min.apply({},YourArray);
minKey    = getCertainKey(YourArray,minHeight);
maxHeight = Math.max.apply({},YourArray);
maxKey    = getCertainKey(YourArray,minHeight);
function getCertainKey(array,certainValue){
   for(var key in array){
      if (array[key]==certainValue)
         return key;
   }
} 

You can also evaluate your output as a sub-process, by surrounding everything with back ticks or with putting it inside $():

`ps aux | grep -ie amarok | awk '{print "kill -9 " $2}'`

 $(ps aux | grep -ie amarok | awk '{print "kill -9 " $2}')     

Try this as the above suggestions didn't work for me when I wanted to do this for a TextView:

TextView.setScrollbarFadingEnabled(false);

Good Luck.

You can factor out your common logic to a private method, for example called Initialize that gets called from both constructors.

Due to the fact that you want to perform argument validation you cannot resort to constructor chaining.

Example:

public Point2D(double x, double y)
{
    // Contracts

    Initialize(x, y);
}

public Point2D(Point2D point)
{
    if (point == null)
        throw new ArgumentNullException("point");

    // Contracts

    Initialize(point.X, point.Y);
}

private void Initialize(double x, double y)
{
    X = x;
    Y = y;
}

You will need to use the IO.Directory.GetFiles function.

Dim files() As String = IO.Directory.GetFiles("c:\")

For Each file As String In files
  ' Do work, example
  Dim text As String = IO.File.ReadAllText(file)

After spending a couple of hours today trying every solution here, I was still unable to get past this exact error. I have used gmail many times in this way so I knew it was something dumb, but nothing I did fixed the problem. I finally stumbled across the solution in my case so thought I would share.

First, most of the answers above are also required, but in my case, it was a simple matter of ordering of the code while creating the SmtpClient class.

In this first code snippet below, notice where the Credentials = creds line is located. This implementation will generate the error referenced in this question even if you have everything else set up properly.

System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient
{
    Host = Emailer.Host,
    Port = Emailer.Port,
    Credentials = creds,
    EnableSsl = Emailer.RequireSSL,
    UseDefaultCredentials = false,
    DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network
}

However, if you move the Credentials setter call to the bottom, the email will be sent without error. I made no changes to the surrounding code...ie...the username/password, etc. Clearly, either the EnableSSL, UseDefaultCredentials, or the DeliveryMethod is dependent on the Credentials being set first... I didn't test all to figure out which one it was though.

System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient
{
    Host = Emailer.Host,
    Port = Emailer.Port,
    EnableSsl = Emailer.RequireSSL,
    UseDefaultCredentials = false,
    DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network,
    Credentials = creds
}

Hope this helps save someone else some headaches in the future.

using ng-keyup directive in angularJS, only send a message on pressing Enter key and Shift+Enter will just take a new line.

Another Solution to isolate a character in a string

package main
import "fmt"

   func main() {
        var word string = "ZbjTS"

       // P R I N T 
       fmt.Println(word)
       yo := string([]rune(word)[0])
       fmt.Println(yo)

       //I N D E X 
       x :=0
       for x < len(word){
           yo := string([]rune(word)[x])
           fmt.Println(yo)
           x+=1
       }

}

for string arrays also:

fmt.Println(string([]rune(sArray[0])[0]))

// = commented line

Here is how I do this.

Dim TAV() As Variant
Dim ArrayToPreserve() as Variant

TAV = ArrayToPreserve
ReDim ArrayToPreserve(nDim1, nDim2)
For i = 0 To UBound(TAV, 1)
    For j = 0 To UBound(TAV, 2)
        ArrayToPreserve(i, j) = TAV(i, j)
    Next j
Next i

Add these two properties to your parent layout (ex: Linear Layout, Relative Layout)

android:focusable="true"
android:focusableInTouchMode="true" 

It will do the trick :)

Windows 7 x32 I found that no matter what I did, the driver being used dated back to 2006. It would not update, in fact Windows appears to be preferring the old driver to the new. I eventually found a way to sort it.

The Device Manager contains 'ghost' drivers that need to be deleted (if you have the same problem as I). To see them requires setting a variable in the registry, restarting and then deleting the likely redundant drivers.

Open the Device Manager from the command line use devmgmt.msc There are other ways, but this is easiest to describe. Currently it shows only 'current' drivers.

Open the System Properties box. Via Command line use sysdm.cpl

** Be aware that playing with area of your computer can break it. Back away if you are at all unsure of this. **

1. Open the Advanced tab, click Environmental Variables.
2. Under System Variables, click New.
3. Enter variable name devmgr_show_nonpresent_devices, under value enter 1.
4. Restart your computer.

Re-open the Device Manager, under view click Show Hidden Devices.

From here delete what you think are the problems then follow the advise you will have read elsewhere. On two seperate computers I have done this and found all I needed to do following this was download and install the standard google drivers as per user3079537's answer above. Good luck.

>>> date
datetime.date(2013, 11, 12)

I found that the first solution in the accepted answer to be problematic for cases where the newline character is still required. The easiest solution to the problem was doing this:

Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.

In jQuery:

$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })

In plain vanilla javaScript (from w3c):

var xmlhttp;
function loadXMLDoc(url)
{
    xmlhttp=null;
if (window.XMLHttpRequest)
  {// code for all new browsers
      xmlhttp=new XMLHttpRequest();
  }
else if (window.ActiveXObject)
  {// code for IE5 and IE6
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
if (xmlhttp!=null)
  {
      xmlhttp.onreadystatechange=state_Change;
      xmlhttp.open("GET",url,true);
      xmlhttp.send(null);
  }
else
  {
      alert("Your browser does not support XMLHTTP.");
  }
}

function state_Change()
{
    if (xmlhttp.readyState==4)
      {// 4 = "loaded"
          if (xmlhttp.status==200)
            {// 200 = OK
             //xmlhttp.data and shtuff
            // ...our code here...
        }
  else
        {
            alert("Problem retrieving data");
        }
  }
}

I had the similar problem: EOF -warning and only part of data was loading with read.csv(). I tried the quotes="", but it only removed the EOF -warning.

But looking at the first row that was not loading, I found that there was a special character, an arrow ? (hexadecimal value 0x1A) in one of the cells. After deleting the arrow I got the data to load normally.

Be sure that you have downloaded the correct API for the version you device is using. After updating your device's Android version or switching to a different device you may not have the correct API downloaded on Android Studio. To do this:

1. Check your devices Android OS version by going to Settings>About Phone>Android Version

2. Make sure you have the correct API installed in Android Studio in the SDK Manager

Given it's SQL 2005, you can also try this It's similar to Oracle's MINUS command (opposite of UNION)

But I would also suggest adding the DATEPART ( hour, insertDate) column for debug

SELECT idCustomer FROM reservations 
EXCEPT
SELECT idCustomer FROM reservations WHERE DATEPART ( hour, insertDate) < 2

Make SymbolIndexer( const SymbolIndexer& ) private. If you're assigning to a reference, you're not copying.

Many frameworks help handle XSS in various ways. When rolling your own or if there's some XSS concern, we can leverage filter_input_array (available in PHP 5 >= 5.2.0, PHP 7.) I typically will add this snippet to my SessionController, because all calls go through there before any other controller interacts with the data. In this manner, all user input gets sanitized in 1 central location. If this is done at the beginning of a project or before your database is poisoned, you shouldn't have any issues at time of output...stops garbage in, garbage out.

/* Prevent XSS input */
$_GET   = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING);
$_POST  = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);
/* I prefer not to use $_REQUEST...but for those who do: */
$_REQUEST = (array)$_POST + (array)$_GET + (array)$_REQUEST;

The above will remove ALL HTML & script tags. If you need a solution that allows safe tags, based on a whitelist, check out HTML Purifier.

If your database is already poisoned or you want to deal with XSS at time of output, OWASP recommends creating a custom wrapper function for echo, and using it EVERYWHERE you output user-supplied values:

//xss mitigation functions
function xssafe($data,$encoding='UTF-8')
{
   return htmlspecialchars($data,ENT_QUOTES | ENT_HTML401,$encoding);
}
function xecho($data)
{
   echo xssafe($data);
}

Easiest way

<?php 
//-- you can modified it like you want

echo $width = "<script>document.write(screen.width);</script>";
echo $height = "<script>document.write(screen.height);</script>";

?>

I had this same issue and I solved it as well by creating a custom renderer for iOS as Falko suggests, however, I avoided the styles modification for Android, I figured out a way to use a custom renderer for Android as well.

It is kind of funky how the selected flag is always false for the android view cell that's why I had to create a new private property to track it. but other than that I think this follows a more appropriate pattern if you want to use custom renderers for both platforms, In my case I did it for TextCell but I believe it applies the same way for other CellViews.

Xamarin Forms

using Xamarin.Forms;

public class CustomTextCell : TextCell
    {
        /// <summary>
        /// The SelectedBackgroundColor property.
        /// </summary>
        public static readonly BindableProperty SelectedBackgroundColorProperty =
            BindableProperty.Create("SelectedBackgroundColor", typeof(Color), typeof(CustomTextCell), Color.Default);

        /// <summary>
        /// Gets or sets the SelectedBackgroundColor.
        /// </summary>
        public Color SelectedBackgroundColor
        {
            get { return (Color)GetValue(SelectedBackgroundColorProperty); }
            set { SetValue(SelectedBackgroundColorProperty, value); }
        }
    }

iOS

public class CustomTextCellRenderer : TextCellRenderer
    {
        public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv)
        {
            var cell = base.GetCell(item, reusableCell, tv);
            var view = item as CustomTextCell;
            cell.SelectedBackgroundView = new UIView
            {
                BackgroundColor = view.SelectedBackgroundColor.ToUIColor(),
            };

            return cell;
        }
    }

Android

public class CustomTextCellRenderer : TextCellRenderer
{
    private Android.Views.View cellCore;
    private Drawable unselectedBackground;
    private bool selected;

    protected override Android.Views.View GetCellCore(Cell item, Android.Views.View convertView, ViewGroup parent, Context context)
    {
        cellCore = base.GetCellCore(item, convertView, parent, context);

        // Save original background to rollback to it when not selected,
        // We assume that no cells will be selected on creation.
        selected = false;
        unselectedBackground = cellCore.Background;

        return cellCore;
    }

    protected override void OnCellPropertyChanged(object sender, PropertyChangedEventArgs args)
    {
        base.OnCellPropertyChanged(sender, args);

        if (args.PropertyName == "IsSelected")
        {
            // I had to create a property to track the selection because cellCore.Selected is always false.
            // Toggle selection
            selected = !selected;

            if (selected)
            {
                var customTextCell = sender as CustomTextCell;
                cellCore.SetBackgroundColor(customTextCell.SelectedBackgroundColor.ToAndroid());
            }
            else
            {
                cellCore.SetBackground(unselectedBackground);
            }
        }
    }
}

...then, in the .xaml page, you need to add an XMLNS reference back to the new CustomViewCell...

xmlns:customuicontrols="clr-namespace:MyMobileApp.CustomUIControls"

And don't forget to make actual use of the new Custom comtrol in your XAML.

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

try this:

.topics tr { line-height: 14px; }

I had FB never being defined. Turned out that I was prototyping functions into the Object class called "merge" and another called "toArray". Both of these screwed up Facebook, no error messages but it wouldn't load.

I changed the names of my prototypes, it works now. Hey, if Facebook is going to prototype Object, shouldn't I be allowed to prototype it?

I have changed the code of serge_gubenko and it works better

for (int i = 0; i < dataGrid.Items.Count; i++)
{
    string txt = searchTxt.Text;
    dataGrid.ScrollIntoView(dataGrid.Items[i]);
    DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(i);
    TextBlock cellContent = dataGrid.Columns[1].GetCellContent(row) as TextBlock;
    if (cellContent != null && cellContent.Text.ToLower().Equals(txt.ToLower()))
    {
        object item = dataGrid.Items[i];
        dataGrid.SelectedItem = item;
        dataGrid.ScrollIntoView(item);
        row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
        break;
    }
}

Here is another alternative using Guava

List<Object> lst ...    
List<String> ls = Lists.transform(lst, Functions.toStringFunction());

You have a variable that contains an address of something. That's a pointer.

Then you have another variable that contains the address of the first variable. That's a pointer to pointer.

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

This is fixed in Hamcrest 1.3. The below code compiles and does not generate any warnings:

// given
List<String> list = new ArrayList<String>();
// then
assertThat(list, is(not(empty())));

But if you have to use older version - instead of bugged empty() you could use:

hasSize(greaterThan(0))
(import static org.hamcrest.number.OrderingComparison.greaterThan; or
import static org.hamcrest.Matchers.greaterThan;)

Example:

// given
List<String> list = new ArrayList<String>();
// then
assertThat(list, hasSize(greaterThan(0)));

The most important thing about above solutions is that it does not generate any warnings. The second solution is even more useful if you would like to estimate minimum result size.

Found an interesting and neat way to export environment variables from a file:

in env.vars:

foo=test

test script:

eval `cat env.vars`
echo $foo         # => test
sh -c 'echo $foo' # => 

export eval `cat env.vars`
echo $foo         # => test
sh -c 'echo $foo' # => test

# a better one. "--" stops processing options, 
# key=value list given as params
export -- `cat env.vars`
echo $foo         # => test
sh -c 'echo $foo' # => test

The map() function is there to apply the same procedure to every item in an iterable data structure, like lists, generators, strings, and other stuff.

Let's look at an example: map() can iterate over every item in a list and apply a function to each item, than it will return (give you back) the new list.

Imagine you have a function that takes a number, adds 1 to that number and returns it:

def add_one(num):
  new_num = num + 1
  return new_num

You also have a list of numbers:

my_list = [1, 3, 6, 7, 8, 10]

if you want to increment every number in the list, you can do the following:

>>> map(add_one, my_list)
[2, 4, 7, 8, 9, 11]

Note: At minimum map() needs two arguments. First a function name and second something like a list.

Let's see some other cool things map() can do. map() can take multiple iterables (lists, strings, etc.) and pass an element from each iterable to a function as an argument.

We have three lists:

list_one = [1, 2, 3, 4, 5]
list_two = [11, 12, 13, 14, 15]
list_three = [21, 22, 23, 24, 25]

map() can make you a new list that holds the addition of elements at a specific index.

Now remember map(), needs a function. This time we'll use the builtin sum() function. Running map() gives the following result:

>>> map(sum, list_one, list_two, list_three)
[33, 36, 39, 42, 45]

REMEMBER:
In Python 2 map(), will iterate (go through the elements of the lists) according to the longest list, and pass None to the function for the shorter lists, so your function should look for None and handle them, otherwise you will get errors. In Python 3 map() will stop after finishing with the shortest list. Also, in Python 3, map() returns an iterator, not a list.

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

First of all, you should be aware of the fact that CUDA will not automagically make computations faster. On the one hand, because GPU programming is an art, and it can be very, very challenging to get it right. On the other hand, because GPUs are well-suited only for certain kinds of computations.

This may sound confusing, because you can basically compute anything on the GPU. The key point is, of course, whether you will achieve a good speedup or not. The most important classification here is whether a problem is task parallel or data parallel. The first one refers, roughly speaking, to problems where several threads are working on their own tasks, more or less independently. The second one refers to problems where many threads are all doing the same - but on different parts of the data.

The latter is the kind of problem that GPUs are good at: They have many cores, and all the cores do the same, but operate on different parts of the input data.

You mentioned that you have "simple math but with huge amount of data". Although this may sound like a perfectly data-parallel problem and thus like it was well-suited for a GPU, there is another aspect to consider: GPUs are ridiculously fast in terms of theoretical computational power (FLOPS, Floating Point Operations Per Second). But they are often throttled down by the memory bandwidth.

This leads to another classification of problems. Namely whether problems are memory bound or compute bound.

The first one refers to problems where the number of instructions that are done for each data element is low. For example, consider a parallel vector addition: You'll have to read two data elements, then perform a single addition, and then write the sum into the result vector. You will not see a speedup when doing this on the GPU, because the single addition does not compensate for the efforts of reading/writing the memory.

The second term, "compute bound", refers to problems where the number of instructions is high compared to the number of memory reads/writes. For example, consider a matrix multiplication: The number of instructions will be O(n^3) when n is the size of the matrix. In this case, one can expect that the GPU will outperform a CPU at a certain matrix size. Another example could be when many complex trigonometric computations (sine/cosine etc) are performed on "few" data elements.

As a rule of thumb: You can assume that reading/writing one data element from the "main" GPU memory has a latency of about 500 instructions....

Therefore, another key point for the performance of GPUs is data locality: If you have to read or write data (and in most cases, you will have to ;-)), then you should make sure that the data is kept as close as possible to the GPU cores. GPUs thus have certain memory areas (referred to as "local memory" or "shared memory") that usually is only a few KB in size, but particularly efficient for data that is about to be involved in a computation.

So to emphasize this again: GPU programming is an art, that is only remotely related to parallel programming on the CPU. Things like Threads in Java, with all the concurrency infrastructure like ThreadPoolExecutors, ForkJoinPools etc. might give the impression that you just have to split your work somehow and distribute it among several processors. On the GPU, you may encounter challenges on a much lower level: Occupancy, register pressure, shared memory pressure, memory coalescing ... just to name a few.

However, when you have a data-parallel, compute-bound problem to solve, the GPU is the way to go.

A general remark: Your specifically asked for CUDA. But I'd strongly recommend you to also have a look at OpenCL. It has several advantages. First of all, it's an vendor-independent, open industry standard, and there are implementations of OpenCL by AMD, Apple, Intel and NVIDIA. Additionally, there is a much broader support for OpenCL in the Java world. The only case where I'd rather settle for CUDA is when you want to use the CUDA runtime libraries, like CUFFT for FFT or CUBLAS for BLAS (Matrix/Vector operations). Although there are approaches for providing similar libraries for OpenCL, they can not directly be used from Java side, unless you create your own JNI bindings for these libraries.

You might also find it interesting to hear that in October 2012, the OpenJDK HotSpot group started the project "Sumatra": http://openjdk.java.net/projects/sumatra/ . The goal of this project is to provide GPU support directly in the JVM, with support from the JIT. The current status and first results can be seen in their mailing list at http://mail.openjdk.java.net/mailman/listinfo/sumatra-dev

However, a while ago, I collected some resources related to "Java on the GPU" in general. I'll summarize these again here, in no particular order.

(Disclaimer: I'm the author of http://jcuda.org/ and http://jocl.org/ )

(Byte)code translation and OpenCL code generation:

https://github.com/aparapi/aparapi : An open-source library that is created and actively maintained by AMD. In a special "Kernel" class, one can override a specific method which should be executed in parallel. The byte code of this method is loaded at runtime using an own bytecode reader. The code is translated into OpenCL code, which is then compiled using the OpenCL compiler. The result can then be executed on the OpenCL device, which may be a GPU or a CPU. If the compilation into OpenCL is not possible (or no OpenCL is available), the code will still be executed in parallel, using a Thread Pool.

https://github.com/pcpratts/rootbeer1 : An open-source library for converting parts of Java into CUDA programs. It offers dedicated interfaces that may be implemented to indicate that a certain class should be executed on the GPU. In contrast to Aparapi, it tries to automatically serialize the "relevant" data (that is, the complete relevant part of the object graph!) into a representation that is suitable for the GPU.

https://code.google.com/archive/p/java-gpu/ : A library for translating annotated Java code (with some limitations) into CUDA code, which is then compiled into a library that executes the code on the GPU. The Library was developed in the context of a PhD thesis, which contains profound background information about the translation process.

https://github.com/ochafik/ScalaCL : Scala bindings for OpenCL. Allows special Scala collections to be processed in parallel with OpenCL. The functions that are called on the elements of the collections can be usual Scala functions (with some limitations) which are then translated into OpenCL kernels.

Language extensions

http://www.ateji.com/px/index.html : A language extension for Java that allows parallel constructs (e.g. parallel for loops, OpenMP style) which are then executed on the GPU with OpenCL. Unfortunately, this very promising project is no longer maintained.

http://www.habanero.rice.edu/Publications.html (JCUDA) : A library that can translate special Java Code (called JCUDA code) into Java- and CUDA-C code, which can then be compiled and executed on the GPU. However, the library does not seem to be publicly available.

NUMBER (precision, scale) means precision number of total digits, of which scale digits are right of the decimal point.

NUMBER(2,2) in other words means a number with 2 digits, both of which are decimals. You may mean to use NUMBER(4,2) to get 4 digits, of which 2 are decimals. Currently you can just insert values with a zero integer part.

More info at the Oracle docs.

The simplest way is using the Multiplicative formula. It works for (n,n) and (n,0) as expected.

def coefficient(n,k):
    c = 1.0
    for i in range(1, k+1):
        c *= float((n+1-i))/float(i)
    return c

Multiplicative formula

@Leniel this method is good but you need to add width to all the floating div's. I would say make them equal width or assign fixed width. Something like

.content-wrapper > div { width:33.3%; }

you may assign class names to each div rather than adding inline style, which is not a good practice.

Be sure to use a clearfix div or clear div to avoid following content remains below these div's.

You can find details of how to use clearfix div here

The best way for add the column in PHP > PDO :

$Add = $dbh->prepare("ALTER TABLE `YourCurrentTable` ADD `YourNewColumnName` INT NOT NULL");
$Add->execute();

Note: the column in the table is not repeatable, that means we don't need to check the existance of a column, but for solving the problem we check the above code:

for example if it works alert 1,if not 0, which means the column exist ! :)

Link statically to libstdc++ with -static-libstdc++ gcc option.

Quick fix, add this in your options:

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false)

Now you have no idea what host you're actually connecting to, because cURL will not verify the certificate in any way. Hope you enjoy man-in-the-middle attacks!

Or just add it to your current function:

/**
 * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
 * array containing the HTTP server response header fields and content.
 */
function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_SSL_VERIFYPEER => false     // Disabled SSL Cert checks
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}

the value selected in the model takes advantage instead of the default item. (I agree I didn't read all posts)

This is a more complicated issue than many may think. Several browsers support built-in JavaScript location objects and associated parameters/methods accessible through window.location or document.location. However, different flavors of Internet Explorer (6,7) don't support these methods in the same way, (window.location.href? window.location.replace() not supported) so you have to access them differently by writing conditional code all the time to hand-hold Internet Explorer.

So, if you have jQuery available and loaded, you might as well use jQuery (location), as the others mentioned because it resolves these issues. If however, you are doing-for an example-some client-side geolocation redirection via JavaScript (that is, using Google Maps API and location object methods), then you may not want to load the entire jQuery library and write your conditional code that checks every version of Internet Explorer/Firefox/etc.

Internet Explorer makes the front-end coding cat unhappy, but jQuery is a plate of milk.

Another way to achieve this is to add a class .btn-space in your buttons

  <button type="button" class="btn btn-outline-danger btn-space"
  </button>
  <button type="button" class="btn btn-outline-primary btn-space"
  </button>

and define this class as follows

.btn-space {
    margin-right: 15px;
}

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.

No, that's not true. The session-timeout configures a per session timeout in case of inactivity.

Are these methods equivalent? Should I favour the web.xml config?

The setting in the web.xml is global, it applies to all sessions of a given context. Programatically, you can change this for a particular session.

XML Schema requires that the xml namespace be declared and imported before using xml:lang (and other xml namespace values) RELAX NG predeclares the xml namespace, as in XML, so no additional declaration is needed.

Reorient your mental model of the functionality of "CASCADE" by thinking of adding a FK to an already existing cascade (i.e. a waterfall). The source of this waterfall is a primary key (PK). Deletes flow down.

So if you define a FK's on_delete as "CASCADE," you're adding this FK's record to a cascade of deletes originating from the PK. The FK's record may participate in this cascade or not ("SET_NULL"). In fact, a record with a FK may even prevent the flow of the deletes! Build a dam with "PROTECT."

Found this answer here and wanted to reference it as it appear much cleaner than the accepted answer:

function blobToDataURL(blob, callback) {
  var fileReader = new FileReader();
  fileReader.onload = function(e) {callback(e.target.result);}
  fileReader.readAsDataURL(blob);
}

This is an example of how to POST multi-part data WITHOUT using external Apache libraries:

byte[] buffer = getBuffer();

if(buffer.length > 0) {
   String lineEnd = "\r\n"; 
   String twoHyphens = "--"; 
   String boundary =  "RQdzAAihJq7Xp1kjraqf"; 

   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   DataOutputStream dos = new DataOutputStream(baos);

   // Send parameter #1
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param1\"" + lineEnd);
   dos.writeBytes("Content-Type: text/plain; charset=US-ASCII" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: 8bit" + lineEnd);
   dos.writeBytes(lineEnd);
   dos.writeBytes(myStringData + lineEnd);

   // Send parameter #2
   //dos.writeBytes(twoHyphens + boundary + lineEnd); 
   //dos.writeBytes("Content-Disposition: form-data; name=\"param2\"" + lineEnd + lineEnd);
   //dos.writeBytes("foo2" + lineEnd);

   // Send a binary file
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param3\";filename=\"test_file.dat\"" + lineEnd); 
   dos.writeBytes("Content-Type: application/octet-stream" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);
   dos.writeBytes(lineEnd); 
   dos.write(buffer);
   dos.writeBytes(lineEnd); 
   dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
   dos.flush(); 
   dos.close();

   ByteArrayInputStream content = new ByteArrayInputStream(baos.toByteArray());
   BasicHttpEntity entity = new BasicHttpEntity();
   entity.setContent(content);

   HttpPost httpPost = new HttpPost(myURL);
   httpPost.addHeader("Connection", "Keep-Alive");
   httpPost.addHeader("Content-Type", "multipart/form-data; boundary="+boundary);

   //MultipartEntity entity = new MultipartEntity();
   //entity.addPart("param3", new ByteArrayBody(buffer, "test_file.dat"));
   //entity.addPart("param1", new StringBody(myStringData));

   httpPost.setEntity(entity);

   /*
   String httpData = "";
   ByteArrayOutputStream baos1 = new ByteArrayOutputStream();
   entity.writeTo(baos1);
   httpData = baos1.toString("UTF-8");
   */

   /*
   Header[] hdrs = httpPost.getAllHeaders();
   for(Header hdr: hdrs) {
     httpData += hdr.getName() + " | " + hdr.getValue() + " |_| ";
   }
   */

   //Log.e(TAG, "httpPost data: " + httpData);
   response = httpClient.execute(httpPost);
}

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

You can also use the regex,

import re

eg:-1) word = "3487954"

re.match('^[0-9]*$',word)

eg:-2) word = "3487.954"

re.match('^[0-9\.]*$',word)

eg:-3) word = "3487.954 328"

re.match('^[0-9\.\ ]*$',word)

As you can see all 3 eg means that there is only no in your string. So you can follow the respective solutions given with them.

To go one step further, I assume you want to do something with these dtypes. df.dtypes.to_dict() comes in handy.

my_type = 'float64' #<---

dtypes = dataframe.dtypes.to_dict()

for col_nam, typ in dtypes.items():
    if (typ != my_type): #<---
        raise ValueError(f"Yikes - `dataframe['{col_name}'].dtype == {typ}` not {my_type}")

You'll find that Pandas did a really good job comparing NumPy classes and user-provided strings. For example: even things like 'double' == dataframe['col_name'].dtype will succeed when .dtype==np.float64.

ByteArrayInputStream also does the trick:

InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) );

Then convert to reader:

InputStreamReader reader = new InputStreamReader(is);

l=[['A', 1], ['B', 2], ['C', 3]]
d={}
for i,j in l:
d.setdefault(i,j)
print(d)

<html>
<div style="width:100%; height:100%; position:fixed; left:0;top:0;overflow:hidden;">

</div>
</html>

eldNew <- eld[-14,]

See ?"[" for a start ...

For ‘[’-indexing only: ‘i’, ‘j’, ‘...’ can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match the corresponding extent. ‘i’, ‘j’, ‘...’ can also be negative integers, indicating elements/slices to leave out of the selection.

(emphasis added)

edit: looking around I notice How to delete the first row of a dataframe in R? , which has the answer ... seems like the title should have popped to your attention if you were looking for answers on SO?

edit 2: I also found How do I delete rows in a data frame? , searching SO for delete row data frame ...

Web application is better in performance as you are publishing a precompiled code, the code is 100% compiled successfully.

Meanwhile web site is better in maintainability as you can change the code easily and the changes will take effect immediately without any build, in this case the page is going to be compiled when it is called for the first time which means it might cause compilation error or crashes in your page whenever it is being called. Each one has its own pros and cons

Check the difference here, it is helpful to understand more about both.

Here is the perfect solution. You should use JQuery datepicker to user input date. It is very easy to use and it have lot of features that HTML input date don't have.

I had some difficulty using the solutions already suggested for my specific use case, but figured it out eventually. I don't think my specific case is worthy of a new question, so I am posting my solution here for reference. (This is very closely related to the question and provides a solution for anyone else with a similar case to mine).

The code I ended up with looks like this:

public class HideableControl<T>: Control where T: class
{
    private string _propertyName;
    private PropertyInfo _propertyInfo;

    public string PropertyName
    {
        get { return _propertyName; }
        set
        {
            _propertyName = value;
            _propertyInfo = typeof(T).GetProperty(value);
        }
    }

    protected override bool GetIsVisible(IRenderContext context)
    {
        if (_propertyInfo == null)
            return false;

        var model = context.Get<T>();

        if (model == null)
            return false;

        return (bool)_propertyInfo.GetValue(model, null);
    }

    protected void SetIsVisibleProperty(Expression<Func<T, bool>> propertyLambda)
    {
        var expression = propertyLambda.Body as MemberExpression;
        if (expression == null)
            throw new ArgumentException("You must pass a lambda of the form: 'vm => vm.Property'");

        PropertyName = expression.Member.Name;
    }
}

public interface ICompanyViewModel
{
    string CompanyName { get; }
    bool IsVisible { get; }
}

public class CompanyControl: HideableControl<ICompanyViewModel>
{
    public CompanyControl()
    {
        SetIsVisibleProperty(vm => vm.IsVisible);
    }
}

The important part for me is that in the CompanyControl class the compiler will only allow me to choose a boolean property of ICompanyViewModel which makes it easier for other developers to get it right.

The main difference between my solution and the accepted answer is that my class is generic and I only want to match properties from the generic type that are boolean.

I also adopted imageio, but I found the following machinery useful for pre- and post-processing:

import imageio
import numpy as np

def imload(*a, **k):
    i = imageio.imread(*a, **k)
    i = i.transpose((1, 0, 2))  # x and y are mixed up for some reason...
    i = np.flip(i, 1)  # make coordinate system right-handed!!!!!!
    return i/255


def imsave(i, url, *a, **k):
    # Original order of arguments was counterintuitive. It should
    # read verbally "Save the image to the URL" — not "Save to the
    # URL the image."

    i = np.flip(i, 1)
    i = i.transpose((1, 0, 2))
    i *= 255

    i = i.round()
    i = np.maximum(i, 0)
    i = np.minimum(i, 255)

    i = np.asarray(i, dtype=np.uint8)

    imageio.imwrite(url, i, *a, **k)

The rationale is that I am using numpy for image processing, not just image displaying. For this purpose, uint8s are awkward, so I convert to floating point values ranging from 0 to 1.

When saving images, I noticed I had to cut the out-of-range values myself, or else I ended up with a really gray output. (The gray output was the result of imageio compressing the full range, which was outside of [0, 256), to values that were inside the range.)

There were a couple other oddities, too, which I mentioned in the comments.

As explained in Django docs, initial is not default.

• The initial value of a field is intended to be displayed in an HTML . But if the user delete this value, and finally send back a blank value for this field, the initial value is lost. So you do not obtain what is expected by a default behaviour.

• The default behaviour is : the value that validation process will take if data argument do not contain any value for the field.

To implement that, a straightforward way is to combine initial and clean_<field>():

class JournalForm(ModelForm):
    tank = forms.IntegerField(widget=forms.HiddenInput(), initial=123) 

    (...)

    def clean_tank(self):
        if not self['tank'].html_name in self.data:
            return self.fields['tank'].initial
        return self.cleaned_data['tank']

If you use git LFS, git count-objects does not count your binaries, but only the pointers to them.

If your LFS files are managed by Artifactorys, you should use the REST API:

• Get the www.jfrog.com API from any search engine
• Look at Get Storage Summary Info

Java

This should work:

// Gets linearlayout
LinearLayout layout = findViewById(R.id.numberPadLayout);
// Gets the layout params that will allow you to resize the layout
LayoutParams params = layout.getLayoutParams();
// Changes the height and width to the specified *pixels*
params.height = 100;
params.width = 100;
layout.setLayoutParams(params);

If you want to convert dip to pixels, use this:

int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, <HEIGHT>, getResources().getDisplayMetrics());

Kotlin

Set up a simple repository using a web server with its default configuration. The key is the directory structure. The documentation does not mention it explicitly, but it is the same structure as a local repository.

To set up an internal repository just requires that you have a place to put it, and then start copying required artifacts there using the same layout as in a remote repository such as repo.maven.apache.org. Source

Add a file to your repository like this:

mvn install:install-file \
  -Dfile=YOUR_JAR.jar -DgroupId=YOUR_GROUP_ID 
  -DartifactId=YOUR_ARTIFACT_ID -Dversion=YOUR_VERSION \
  -Dpackaging=jar \
  -DlocalRepositoryPath=/var/www/html/mavenRepository

If your domain is example.com and the root directory of the web server is located at /var/www/html/, then maven can find "YOUR_JAR.jar" if configured with <url>http://example.com/mavenRepository</url>.

If you deal with bandwidth problems, try to compress data at the client side first, then base64-it.

Nice example of such magic is at http://jszip.stuartk.co.uk/ and more discussion to this topic is at JavaScript implementation of Gzip

void transfer(double x) {
unsigned long long* p = (unsigned long long*)&x;
for (int i = sizeof(unsigned long long) * 8 - 1; i >= 0; i--) {cout<< ((*p) >>i & 1);}}

Nothing wrong with your method, it's a G-mail security issue.

1. Login g-mail account settings.

2. Enable 2-step verification.

3. Generate app-password.

4. Use new-generated password in place of your real g-mail password.

Don't forget to clear cache.

php artisan config:cache.
php artisan config:clear.

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=generatedAppPassword
MAIL_ENCRYPTION=tls

You should add fstream::out to open method like this:

file.open("test.txt",fstream::out);

More information about fstream flags, check out this link: http://www.cplusplus.com/reference/fstream/fstream/open/

      $filename= time()."pdf"; 
    //$filelocation = "C://xampp/htdocs/Nilesh/Projects/mkGroup/admin/PDF";

     $filelocation = "/pdf uplaod path/";
     $fileNL = $filelocation."/".$filename;

       $pdf->Output($fileNL,'F');
       $pdf->Output($filename, 'S');

This is a very broad question, so I am going to give a broad answer.

1. A query gets suspended when it is requesting access to a resource that is currently not available. This can be a logical resource like a locked row or a physical resource like a memory data page. The query starts running again, once the resource becomes available. 
2. High disk IO means that a lot of data pages need to be accessed to fulfill the request.

That is all that I can tell from the above screenshot. However, if I were to speculate, you probably have an IO subsystem that is too slow to keep up with the demand. This could be caused by missing indexes or an actually too slow disk. Keep in mind, that 15000 reads for a single OLTP query is slightly high but not uncommon.

You can use the Range object in VBA to set the value of a named cell, just like any other cell.

Range("C1").Value = Inputbox("Which job number would you like to add to the list?)

Where "C1" is the name of the cell you want to update.

My Excel VBA is a little bit old and crusty, so there may be a better way to do this in newer versions of Excel.

Use +, the string concatenation operator:

ed = (EditText) findViewById (R.id.box);
int x = 10;
ed.setText(""+x);

or use String.valueOf(int):

ed.setText(String.valueOf(x));

or use Integer.toString(int):

ed.setText(Integer.toString(x));

Simple and clean solution using Interface Builder

Add a file named UIView.swift in your project (or just paste this in any file) :

import UIKit

@IBDesignable extension UIView {

    /* The color of the shadow. Defaults to opaque black. Colors created
    * from patterns are currently NOT supported. Animatable. */
    @IBInspectable var shadowColor: UIColor? {
        set {
            layer.shadowColor = newValue!.CGColor
        }
        get {
            if let color = layer.shadowColor {
                return UIColor(CGColor:color)
            }
            else {
                return nil
            }
        }
    }

    /* The opacity of the shadow. Defaults to 0. Specifying a value outside the
    * [0,1] range will give undefined results. Animatable. */
    @IBInspectable var shadowOpacity: Float {
        set {
            layer.shadowOpacity = newValue
        }
        get {
            return layer.shadowOpacity
        }
    }

    /* The shadow offset. Defaults to (0, -3). Animatable. */
    @IBInspectable var shadowOffset: CGPoint {
        set {
            layer.shadowOffset = CGSize(width: newValue.x, height: newValue.y)
        }
        get {
            return CGPoint(x: layer.shadowOffset.width, y:layer.shadowOffset.height)
        }
    }

    /* The blur radius used to create the shadow. Defaults to 3. Animatable. */
    @IBInspectable var shadowRadius: CGFloat {
        set {
            layer.shadowRadius = newValue
        }
        get {
            return layer.shadowRadius
        }
    }
}

Then this will be available in Interface Builder for every view in the Utilities Panel > Attributes Inspector :

You can easily set the shadow now.

Notes:
- The shadow won't appear in IB, only at runtime.
- As Mazen Kasser said

To those who failed in getting this to work [...] make sure Clip Subviews (clipsToBounds) is not enabled

Number(Math.round(1.005+'e2')+'e-2'); // 1.01

This worked for me: Rounding Decimals in JavaScript

Either != or ne will work, but you need to get the accessor syntax and nested quotes sorted out.

<c:if test="${content.contentType.name ne 'MCE'}">
    <%-- snip --%>
</c:if>

I think you need use List or classes based on that.

For instance,

ArrayList<Integer> integers = new ArrayList<Integer>();
int j;

do{
    integers.add(int.nextInt());
    j++;
}while( (integers.get(j-1) >= 1) || (integers.get(j-1) <= 100) );

You could read this article for getting more information about how to use that.

With this command:

 dpkg -s mysql-server | grep Status
