div hover background color change

Try like this:

.class_name:hover{
    background-color:#FF0000;
}

What else happens between these function calls?

The various directive functions are executed from within two other angular functions called $compile (where the directive's compile is executed) and an internal function called nodeLinkFn (where the directive's controller, preLink and postLink are executed). Various things happen within the angular function before and after the directive functions are called. Perhaps most notably is the child recursion. The following simplified illustration shows key steps within the compile and link phases:

To demonstrate the these steps, let's use the following HTML markup:

<div ng-repeat="i in [0,1,2]">
    <my-element>
        <div>Inner content</div>
    </my-element>
</div>

With the following directive:

myApp.directive( 'myElement', function() {
    return {
        restrict:   'EA',
        transclude: true,
        template:   '<div>{{label}}<div ng-transclude></div></div>'
    }
});

Compile

The compile API looks like so:

compile: function compile( tElement, tAttributes ) { ... }

Often the parameters are prefixed with t to signify the elements and attributes provided are those of the source template, rather than that of the instance.

Prior to the call to compile transcluded content (if any) is removed, and the template is applied to the markup. Thus, the element provided to the compile function will look like so:

<my-element>
    <div>
        "{{label}}"
        <div ng-transclude></div>
    </div>
</my-element>

Notice that the transcluded content is not re-inserted at this point.

Following the call to the directive's .compile, Angular will traverse all child elements, including those that may have just been introduced by the directive (the template elements, for instance).

Instance creation

In our case, three instances of the source template above will be created (by ng-repeat). Thus, the following sequence will execute three times, once per instance.

Controller

The controller API involves:

controller: function( $scope, $element, $attrs, $transclude ) { ... }

Entering the link phase, the link function returned via $compile is now provided with a scope.

First, the link function create a child scope (scope: true) or an isolated scope (scope: {...}) if requested.

The controller is then executed, provided with the scope of the instance element.

Pre-link

The pre-link API looks like so:

function preLink( scope, element, attributes, controller ) { ... }

Virtually nothing happens between the call to the directive's .controller and the .preLink function. Angular still provide recommendation as to how each should be used.

Following the .preLink call, the link function will traverse each child element - calling the correct link function and attaching to it the current scope (which serves as the parent scope for child elements).

Post-link

The post-link API is similar to that of the pre-link function:

function postLink( scope, element, attributes, controller ) { ... }

Perhaps worth noticing that once a directive's .postLink function is called, the link process of all its children elements has completed, including all the children's .postLink functions.

This means that by the time .postLink is called, the children are 'live' are ready. This includes:

• data binding
• transclusion applied
• scope attached

The template at this stage will thus look like so:

<my-element>
    <div class="ng-binding">
        "{{label}}"
        <div ng-transclude>                
            <div class="ng-scope">Inner content</div>
        </div>
    </div>
</my-element>

Use sorted function, like this:

map(lambda x: sorted(x)[1],lst)

You may find that gnuplot's for loops are useful in this case, if you adjust your filenames or graph titles appropriately.

e.g.

filenames = "first second third fourth fifth"
plot for [file in filenames] file."dat" using 1:2 with lines

and

filename(n) = sprintf("file_%d", n)
plot for [i=1:10] filename(i) using 1:2 with lines

If you mean by newline the newline character it is \n and \r is the carrier return character, but if you mean by newline the line ending then it depends on the operating system: DOS uses carriage return and line feed ("\r\n") as a line ending, which Unix uses just line feed ("\n")

Sync folder remove with the files or only a file.

I am not much of a giver nor a contributor but I couldn't find a good solution of this problem and I had to find my way... so I hope you'll like it :)

Works perfect for me with any number of nested directories and sub directories. Caution for the scope of 'this' when recursing the function, your implementation may be different. In my case this function stays into the return of another function that's why I am calling it with this.

    const fs = require('fs');

    deleteFileOrDir(path, pathTemp = false){
            if (fs.existsSync(path)) {
                if (fs.lstatSync(path).isDirectory()) {
                    var files = fs.readdirSync(path);
                    if (!files.length) return fs.rmdirSync(path);
                    for (var file in files) {
                        var currentPath = path + "/" + files[file];
                        if (!fs.existsSync(currentPath)) continue;
                        if (fs.lstatSync(currentPath).isFile()) {
                            fs.unlinkSync(currentPath);
                            continue;
                        }
                        if (fs.lstatSync(currentPath).isDirectory() && !fs.readdirSync(currentPath).length) {
                            fs.rmdirSync(currentPath);
                        } else {
                            this.deleteFileOrDir(currentPath, path);
                        }
                    }
                    this.deleteFileOrDir(path);
                } else {
                    fs.unlinkSync(path);
                }
            }
            if (pathTemp) this.deleteFileOrDir(pathTemp);
        }

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

There is a much easier and more compact solution for multilevel prototype lookup, but it requires Proxy support. Usage: SUPER(<instance>).<method>(<args>), for example, assuming two classes A and B extends A with method m: SUPER(new B).m().

function SUPER(instance) {
    return new Proxy(instance, {
        get(target, prop) {
            return Object.getPrototypeOf(Object.getPrototypeOf(target))[prop].bind(target);
        }
    });
}

State resides within a component where as props are passed from parent to child. Props are generally immutable.

class Parent extends React.Component {
    constructor() {
        super();
        this.state = {
            name : "John",
        }
    }
    render() {
        return (
            <Child name={this.state.name}>
        )
    }
}

class Child extends React.Component {
    constructor() {
        super();
    }

    render() {
        return(
            {this.props.name} 
        )
    }
}

In the above code, we have a parent class(Parent) which has name as its state which is passed to the child component(Child class) as a prop and the child component renders it using {this.props.name}

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

There is a smart way to disable inspect element in your website. Just add the following snippet inside script tag :

$(document).bind("contextmenu",function(e) {
 e.preventDefault();
});

Please check out this blog

The function key F12 which directly take inspect element from browser, we can also disable it, by using the following code:

$(document).keydown(function(e){
    if(e.which === 123){
       return false;
    }
});

Look at the HttpServletResponse#sendRedirect(String location) method.

Use it as:

response.sendRedirect(request.getContextPath() + "/welcome.jsp")

Alternatively, look at HttpServletResponse#setHeader(String name, String value) method.

The redirection is set by adding the location header:

response.setHeader("Location", request.getContextPath() + "/welcome.jsp");

var data = {
    "items": [{
        "id": 1,
        "category": "cat1"
    }, {
        "id": 2,
        "category": "cat2"
    }, {
        "id": 3,
        "category": "cat1"
    }]
};

var returnedData = $.grep(data.items, function (element, index) {
    return element.id == 1;
});


alert(returnedData[0].id + "  " + returnedData[0].category);

The returnedData is returning an array of objects, so you can access it by array index.

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json

r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

I am not saying that you have to abandon PHP, but you need different technologies here.

Let's start off simple (without Akamai :-)) and think about the implications here. Video, chat, etc. - it's all client-side in the beginning. The user has a webcam, you want to grab the signal somehow and send it to the server. There is no PHP so far.

I know that Flash supports this though (check this tutorial on webcams and flash) so you could use Flash to transport the content to the server. I think if you'll stay with Flash, then Flex (flex and webcam tutorial) is probably a good idea to look into.

So those are just the basics, maybe it gives you an idea of where you need to research because obviously this won't give you a full video chat inside your app yet. For starters, you will need some sort of way to record the streams and re-publish them so others see other people from the chat, etc..

I'm also not sure how much traffic and bandwidth this is gonna consume though and generally, you will need way more than a Stackoverflow question to solve this issue. Best would be to do a full spec of your app and then hire some people to help you build it.

HTH!

another simple approach with modern built-in stuff like PercentRelativeLayout is now available for new users who hit this problem. thanks to android team for release this item.

<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
app:layout_widthPercent="50%">

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="#55000000"
        android:paddingBottom="15dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:textColor="@android:color/white" />

</FrameLayout>

and for better performance you can use some stuff like picasso image loader which help you to fill whole width of every image parents. for example in your adapter you should use this:

int width= context.getResources().getDisplayMetrics().widthPixels;
    com.squareup.picasso.Picasso
            .with(context)
            .load("some url")
            .centerCrop().resize(width/2,width/2)
            .error(R.drawable.placeholder)
            .placeholder(R.drawable.placeholder)
            .into(item.drawableId);

now you dont need CustomImageView Class anymore.

P.S i recommend to use ImageView in place of Type Int in class Item.

hope this help..

@Manuel was part way there. You can add the compiler option as well, like this:

If you have CMake 3.1.0+, this becomes even easier:

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
target_link_libraries(my_app PRIVATE Threads::Threads)

If you are using CMake 2.8.12+, you can simplify this to:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  target_compile_options(my_app PUBLIC "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

Older CMake versions may require:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  set_property(TARGET my_app PROPERTY COMPILE_OPTIONS "-pthread")
  set_property(TARGET my_app PROPERTY INTERFACE_COMPILE_OPTIONS "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

If you want to use one of the first two methods with CMake 3.1+, you will need set(THREADS_PREFER_PTHREAD_FLAG ON) there too.

Try adding a Reference to System.Configuration, you get some of the configuration namespace by referencing the System namespace, adding the reference to System.Configuration should allow you to access ConfigurationManager.

This isn't a direct answer to the question (loading images >2048), but a possible solution for anyone experiencing the error.

In my case, the image was smaller than 2048 in both dimensions (1280x727 to be exact) and the issue was specifically experienced on a Galaxy Nexus. The image was in the drawable folder and none of the qualified folders. Android assumes drawables without a density qualifier are mdpi and scales them up or down for other densities, in this case scaled up 2x for xhdpi. Moving the culprit image to drawable-nodpi to prevent scaling solved the problem.

Displaying an image from MySql Db.

$db = mysqli_connect("localhost","root","","DbName"); 
$sql = "SELECT * FROM products WHERE id = $id";
$sth = $db->query($sql);
$result=mysqli_fetch_array($sth);
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result['image'] ).'"/>';

I had the same problem - and I have read all these answers, but unfortunately none of them worked for me. Eventually I tried removing this line

%\usepackage[latin1]{inputenc}

and all errors disappeared.

.remove() should remove all of them. I think the problem is that you're using an ID. There's only supposed to be one HTML element with a particular ID on the page, so jQuery is optimizing and not searching for them all. Use a class instead.

This is very similar to another stackoverflow article, Bind a function to Twitter Bootstrap Modal Close. Assuming you are using some version of Bootstap v3 or v4, you can do something like the following:

$("#myModal").on("hidden.bs.modal", function () {
    // put your default event here
});

You can also use this script to figure out more info:

EXEC sp_server_info

The result will be something like that:

           ?  ?                       ?

You can loop over each row of the DataTable and check the value.

I'm a big fan of using a foreach loop when using IEnumerables. Makes it very simple and clean to look at or process each row

DataTable dtPs = // ... initialize your DataTable
foreach (DataRow dr in dtPs.Rows)
{
    if (dr["item_manuf_id"].ToString() == "some value")
    {
        // do your deed
    }
}

Alternatively you can use a PrimaryKey for your DataTable. This helps in various ways, but you often need to define one before you can use it.

An example of using one if at http://msdn.microsoft.com/en-us/library/z24kefs8(v=vs.80).aspx

DataTable workTable = new DataTable("Customers");

// set constraints on the primary key
DataColumn workCol = workTable.Columns.Add("CustID", typeof(Int32));
workCol.AllowDBNull = false;
workCol.Unique = true;

workTable.Columns.Add("CustLName", typeof(String));
workTable.Columns.Add("CustFName", typeof(String));
workTable.Columns.Add("Purchases", typeof(Double));

// set primary key
workTable.PrimaryKey = new DataColumn[] { workTable.Columns["CustID"] };

Once you have a primary key defined and data populated, you can use the Find(...) method to get the rows that match your primary key.

Take a look at http://msdn.microsoft.com/en-us/library/y06xa2h1(v=vs.80).aspx

DataRow drFound = dtPs.Rows.Find("some value");
if (drFound["item_manuf_id"].ToString() == "some value")
{
    // do your deed
}

Finally, you can use the Select() method to find data within a DataTable also found at at http://msdn.microsoft.com/en-us/library/y06xa2h1(v=vs.80).aspx.

String sExpression = "item_manuf_id == 'some value'";
DataRow[] drFound;
drFound = dtPs.Select(sExpression);

foreach (DataRow dr in drFound)
{
    // do you deed. Each record here was already found to match your criteria
}

In my case this problem persisted when I created and saved the svg using Photoshop. What helped, was opening the file using Illustrator and exporting the svg afterwards.

On API >= 11, you can use:

wv.getSettings().setBuiltInZoomControls(true);
wv.getSettings().setDisplayZoomControls(false);

As per the SDK:

public void setDisplayZoomControls (boolean enabled) 

Since: API Level 11

Sets whether the on screen zoom buttons are used. A combination of built in zoom controls enabled and on screen zoom controls disabled allows for pinch to zoom to work without the on screen controls

Mongo dump and restore with uri to local

mongodump --uri "mongodb://USERNAME:PASSWORD@IP_OR_URL:PORT/DB_NAME" --collection COLLECTION_NAME -o LOCAL_URL

Omitting --collection COLLECTION_NAME will dump entire DB.

There are several details you need to 'match up' with for a particular CRC implementation - even using the same polynomial there can be different results because of minor differences in how data bits are handled, using a particular initial value for the CRC (sometimes it's zero, sometimes 0xffff), and/or inverting the bits of the CRC. For example, sometimes one implementation will work from the low order bits of the data bytes up, while sometimes they'll work from the high order bits down (as yours currently does).

Also, you need to 'push out' the last bits of the CRC after you've run all the data bits through.

Keep in mind that CRC algorithms were designed to be implemented in hardware, so some of how bit ordering is handled may not make so much sense from a software point of view.

If you want to match the CRC16 with polynomial 0x8005 as shown on the lammertbies.nl CRC calculator page, you need to make the following changes to your CRC function:

• a) run the data bits through the CRC loop starting from the least significant bit instead of from the most significant bit
• b) push the last 16 bits of the CRC out of the CRC register after you've finished with the input data
• c) reverse the CRC bits (I'm guessing this bit is a carry over from hardware implementations)

So, your function might look like:

#define CRC16 0x8005

uint16_t gen_crc16(const uint8_t *data, uint16_t size)
{
    uint16_t out = 0;
    int bits_read = 0, bit_flag;

    /* Sanity check: */
    if(data == NULL)
        return 0;

    while(size > 0)
    {
        bit_flag = out >> 15;

        /* Get next bit: */
        out <<= 1;
        out |= (*data >> bits_read) & 1; // item a) work from the least significant bits

        /* Increment bit counter: */
        bits_read++;
        if(bits_read > 7)
        {
            bits_read = 0;
            data++;
            size--;
        }

        /* Cycle check: */
        if(bit_flag)
            out ^= CRC16;

    }

    // item b) "push out" the last 16 bits
    int i;
    for (i = 0; i < 16; ++i) {
        bit_flag = out >> 15;
        out <<= 1;
        if(bit_flag)
            out ^= CRC16;
    }

    // item c) reverse the bits
    uint16_t crc = 0;
    i = 0x8000;
    int j = 0x0001;
    for (; i != 0; i >>=1, j <<= 1) {
        if (i & out) crc |= j;
    }

    return crc;
}

That function returns 0xbb3d for me when I pass in "123456789".

>>> Array.apply(null, Array(10)).map(function(){return 5})
[5, 5, 5, 5, 5, 5, 5, 5, 5, 5]
>>> //Or in ES6
>>> [...Array(10)].map((_, i) => 5)
[5, 5, 5, 5, 5, 5, 5, 5, 5, 5]

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

Access has some sort of system tables You can read about it a little here you can fire the folowing query to see if it exists ( 1 = it exists, 0 = it doesnt ;))

SELECT Count([MSysObjects].[Name]) AS [Count]
FROM MSysObjects
WHERE (((MSysObjects.Name)="TblObject") AND ((MSysObjects.Type)=1));

Unlike XML and XHTML, HTML has no knowledge of the self-closing syntax. Browsers that interpret XHTML as HTML don't know that the / character indicates that the tag should be self-closing; instead they interpret it like an empty attribute and the parser still thinks the tag is 'open'.

Just as <script defer> is treated as <script defer="defer">, <script /> is treated as <script /="/">.

fcntl, select, asyncproc won't help in this case.

A reliable way to read a stream without blocking regardless of operating system is to use Queue.get_nowait():

import sys
from subprocess import PIPE, Popen
from threading  import Thread

try:
    from queue import Queue, Empty
except ImportError:
    from Queue import Queue, Empty  # python 2.x

ON_POSIX = 'posix' in sys.builtin_module_names

def enqueue_output(out, queue):
    for line in iter(out.readline, b''):
        queue.put(line)
    out.close()

p = Popen(['myprogram.exe'], stdout=PIPE, bufsize=1, close_fds=ON_POSIX)
q = Queue()
t = Thread(target=enqueue_output, args=(p.stdout, q))
t.daemon = True # thread dies with the program
t.start()

# ... do other things here

# read line without blocking
try:  line = q.get_nowait() # or q.get(timeout=.1)
except Empty:
    print('no output yet')
else: # got line
    # ... do something with line

In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to

Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).

(From How to: Break and Combine Statements in Code)

In other words: Whenever the interpreter encounters the sequence <space>_<line terminator>, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.

To break the statement in your question into several lines you could do the following:

U_matrix(i, j, n + 1) = _
     k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
     (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

(Leading whitespaces are ignored.)

Building off the accepted answer by @dennisg, I accomplished this successfully using jQuery.XDomainRequest.js by MoonScript.

The following code worked correctly in Chrome, Firefox and IE10, but failed in IE9. I simply included the script and it now automagically works in IE9. (And probably 8, but I haven't tested it.)

var displayTweets = function () {
    $.ajax({
        cache: false,
        type: 'GET',
        crossDomain: true,
        url: Site.config().apiRoot + '/Api/GetTwitterFeed',
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        success: function (data) {
            for (var tweet in data) {
                displayTweet(data[tweet]);
            }
        }
    });
};

I also had similar problems when trying to link static compiled fontconfig and expat into a linux shared object:

/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: /3rdparty/fontconfig/lib/linux-x86_64/libfontconfig.a(fccfg.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: /3rdparty/expat/lib/linux-x86_64/libexpat.a(xmlparse.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
[...]

This contrary to the fact that I was already passing -fPIC flags though CFLAGS variable, and other compilers/linkers variants (clang/lld) were perfectly working with the same build configuration. It ended up that these dependencies control position-independent code settings through despicable autoconf scripts and need --with-pic switch during build configuration on linux gcc/ld combination, and its lack probably overrides same the setting in CFLAGS. Pass the switch to configure script and the dependencies will be correctly compiled with -fPIC.

byte[] conv = new byte[4];
conv[3] = (byte) input & 0xff;
input >>= 8;
conv[2] = (byte) input & 0xff;
input >>= 8;
conv[1] = (byte) input & 0xff;
input >>= 8;
conv[0] = (byte) input;

If you want to do this only once, then do it because The framework will call initState() method exactly once for each State object it creates.

 @override
  void initState() {
    super.initState();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => executeAfterBuildComplete(context));
  }

If you want to do this again and again like on back or navigate to a next screen and etc..., then do it because didChangeDependencies() Called when a dependency of this State object changes.

For example, if the previous call to build referenced an InheritedWidget that later changed, the framework would call this method to notify this object about the change.

This method is also called immediately after initState. It is safe to call BuildContext.dependOnInheritedWidgetOfExactType from this method.

 @override
  void didChangeDependencies() {
    super.didChangeDependencies();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => executeAfterBuildComplete(context));
  }

This is the your Callback function

executeAfterBuildComplete([BuildContext context]){
    print("Build Process Complete");
  }

Use this:

    return this.RedirectToAction<AccountController>(m => m.LogIn());

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

Sometimes something really simple, can be answered complex. I am not saying that any of the above answers are incorrect, but I would just apply, that it can be done as simple as this:

I know this question is old, but if anyone just wants to change to pin or marker color, then check out the documentation: https://developers.google.com/maps/documentation/android-sdk/marker

when you add your marker simply set the icon-property:

GoogleMap gMap;
LatLng latLng;
....
// write your code...
....
gMap.addMarker(new MarkerOptions()
    .position(latLng)
    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));

There are 10 default colors to choose from. If that isn't enough (the simple solution) then I would probably go for the more complex given in the other answers, fulfilling a more complex need.

ps: I've written something similar in another answer and therefore I should refer to that answer, but the last time I did that, I was asked to post the answer since it was so short (as this one)..

Developing New Code

Debugging inside IPython

1. Use Jupyter/IPython cell execution to speed up experiment iterations
2. Use %%debug for step through

Cell Example:

%%debug
...: for n in range(4):
...:    n>2

Debugging Existing Code

IPython inside debugging

1. Debugging a broken unit test: pytest ... --pdbcls=IPython.terminal.debugger:TerminalPdb --pdb
2. Debugging outside of test case: breakpoint(), python -m ipdb, etc.
3. IPython.embed() for full IPython functionality where needed while in the debugger

Thoughts on Python

I agree with the OP that many things MATLAB does nicely Python still does not have and really should since just about everything in the language favors development speed over production speed. Maybe someday I will contribute more than trivial bug fixes to CPython.

Since PHP 5.5, you can use array_column:

$ids = array_column($users, 'id');

This is the preferred option on any modern project. However, if you must support PHP<5.5, the following alternatives exist:

Since PHP 5.3, you can use array_map with an anonymous function, like this:

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Before ^{_{(Technically PHP 4.0.6+)}}, you must create an anonymous function with create_function instead:

$ids = array_map(create_function('$ar', 'return $ar["id"];'), $users);

Since this seems to be the number one google hit on base64 encoding and iphone, I felt like sharing my experience with the code snippet above.

It works, but it is extremely slow. A benchmark on a random image (0.4 mb) took 37 seconds on native iphone. The main reason is probably all the OOP magic - single char NSStrings etc, which are only autoreleased after the encoding is done.

Another suggestion posted here (ab)uses the openssl library, which feels like overkill as well.

The code below takes 70 ms - that's a 500 times speedup. This only does base64 encoding (decoding will follow as soon as I encounter it)

+ (NSString *) base64StringFromData: (NSData *)data length: (int)length {
int lentext = [data length]; 
if (lentext < 1) return @"";

char *outbuf = malloc(lentext*4/3+4); // add 4 to be sure

if ( !outbuf ) return nil;

const unsigned char *raw = [data bytes];

int inp = 0;
int outp = 0;
int do_now = lentext - (lentext%3);

for ( outp = 0, inp = 0; inp < do_now; inp += 3 )
{
    outbuf[outp++] = base64EncodingTable[(raw[inp] & 0xFC) >> 2];
    outbuf[outp++] = base64EncodingTable[((raw[inp] & 0x03) << 4) | ((raw[inp+1] & 0xF0) >> 4)];
    outbuf[outp++] = base64EncodingTable[((raw[inp+1] & 0x0F) << 2) | ((raw[inp+2] & 0xC0) >> 6)];
    outbuf[outp++] = base64EncodingTable[raw[inp+2] & 0x3F];
}

if ( do_now < lentext )
{
    char tmpbuf[2] = {0,0};
    int left = lentext%3;
    for ( int i=0; i < left; i++ )
    {
        tmpbuf[i] = raw[do_now+i];
    }
    raw = tmpbuf;
    outbuf[outp++] = base64EncodingTable[(raw[inp] & 0xFC) >> 2];
    outbuf[outp++] = base64EncodingTable[((raw[inp] & 0x03) << 4) | ((raw[inp+1] & 0xF0) >> 4)];
    if ( left == 2 ) outbuf[outp++] = base64EncodingTable[((raw[inp+1] & 0x0F) << 2) | ((raw[inp+2] & 0xC0) >> 6)];
}

NSString *ret = [[[NSString alloc] initWithBytes:outbuf length:outp encoding:NSASCIIStringEncoding] autorelease];
free(outbuf);

return ret;
}

I left out the line-cutting since I didn't need it, but it's trivial to add.

For those who are interested in optimizing: the goal is to minimize what happens in the main loop. Therefore all logic to deal with the last 3 bytes is treated outside the loop.

Also, try to work on data in-place, without additional copying to/from buffers. And reduce any arithmetic to the bare minimum.

Observe that the bits that are put together to look up an entry in the table, would not overlap when they were to be orred together without shifting. A major improvement could therefore be to use 4 separate 256 byte lookup tables and eliminate the shifts, like this:

outbuf[outp++] = base64EncodingTable1[(raw[inp] & 0xFC)];
outbuf[outp++] = base64EncodingTable2[(raw[inp] & 0x03) | (raw[inp+1] & 0xF0)];
outbuf[outp++] = base64EncodingTable3[(raw[inp+1] & 0x0F) | (raw[inp+2] & 0xC0)];
outbuf[outp++] = base64EncodingTable4[raw[inp+2] & 0x3F];

Of course you could take it a whole lot further, but that's beyond the scope here.

In the constructor method of your model class set the default value whatever you want. Then in your first action create an instance of the model and pass it to your view.

    public ActionResult VolunteersAdd()
    {
        VolunteerModel model = new VolunteerModel(); //to set the default values
        return View(model);
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult VolunteersAdd(VolunteerModel model)
    {


        return View(model);
    }

First, don't use update panels. They are the second most evil thing that Microsoft has ever created for the web developer.

Second, if you must use update panels, try setting the UpdateMode property to Conditional. Then add a trigger to an Asp:Hidden control that you add to the page. Assign the change event as the trigger. In your dragstop event, change the value of the hidden control.

This is untested, but the theory seems sound... If this does not work, you could try the same thing with an asp:button, just set the display:none style on it and use the click event instead of the change event.

I had a problem like this where Intellisense didn't seem to recognise the existence of one project (lots of "can't find this type", "this namespace doesn't exist", etc. errors).

Removing and re-adding the project reference in all the referencing projects would fix the issue, but the underlying cause could be fixed by editing the .proj file of the problem project.

Near the top of the "missing" project' .csproj file is an element:

<ProjectGuid>{GUID}</ProjectGuid>

and in all of the referencing projects .csproj files were project references:

<ProjectReference Include="..\OffendingProject\OffendingProject.csproj">
  <Project>{ANOTHER-GUID}</Project>
  <Name>Offending Project</Name>
</ProjectReference>

The referencing GUID didn't match the project's GUID. Replacing {GUID} above with {ANOTHER-GUID} fixed the problem without having to go through every referencing project.

Long Press on Power button, then you will have the option for the screenshot.

You could use if(number >= 0). The fact that you use int number = input.nextInt(); makes sure that it has to be an Integer.

To paraphrase, you can rename it with the .command extension or create an AppleScript to run the shell.

If you are inheriting UITableViewController, you can just init tableView again.

Objective C:

self.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped];

Swift:

self.tableView = UITableView(frame: CGRect.zero, style: .grouped)

Installing fiddler was causing me similar problem. Uninstalling fiddler and removing the fiddler proxy from the machine.config (from both Framework and Framework64) solved the problem.

You are writing if(true) so it will always show "Hello " message.

You should take decision on the basis of value of n returned.

In case you also want to include your real name in the from-field, you can use the following format

mailx -r "[email protected] (My Name)" -s "My Subject" ...

If you happen to have non-ASCII characters in you name, like My AEÆoeøaaå (Æ= C3 86, ø= C3 B8, å= C3 A5), you have to encode them like this:

mailx -r "[email protected] (My =?utf-8?Q?AE=C3=86oe=C3=B8aa=C3=A5?=)" -s "My Subject" ...

Hope this can save someone an hour of hard work/research!

It is rather messy but you need to do something like the following:

START "do something window" dir
FOR /F "tokens=2" %I in ('TASKLIST /NH /FI "WINDOWTITLE eq do something window"' ) DO SET PID=%I
ECHO %PID%
TASKKILL /PID %PID%

In addition to the answer, you can't directly use output redirection operators in the set part of for loop (e.g. if you wanna hide stderror output from a user and provide a nicer error message). Instead, you have to escape them with a caret character (^):

for /f %%O in ('some-erroring-command 2^> nul') do (echo %%O)

• using: You are going to use it.
• namespace: To use what? A namespace.
• std: The std namespace (where features of the C++ Standard Library, such as string or vector, are declared).

After you write this instruction, if the compiler sees string it will know that you may be referring to std::string, and if it sees vector, it will know that you may be referring to std::vector. (Provided that you have included in your compilation unit the header files where they are defined, of course.)

If you don't write it, when the compiler sees string or vector it will not know what you are refering to. You will need to explicitly tell it std::string or std::vector, and if you don't, you will get a compile error.

Follow the steps to store data in Angular - local storage:

1. Add 'ngStorage.js' in your folder.

2. Inject 'ngStorage' in your angular.module

       eg: angular.module("app", [ 'ngStorage']);
   

3. Add $localStorage in your app.controller function

4.You can use $localStorage inside your controller

Eg: $localstorage.login= true;

The above will store the localstorage in your browser application

Regards to your question... counting one Field? I decided to make it a question, but I hope it helps...

Say I have the following DataFrame

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.normal(0, 1, (5, 2)), columns=["A", "B"])

You could count a single column by

df.A.count()
#or
df['A'].count()

both evaluate to 5.

The cool thing (or one of many w.r.t. pandas) is that if you have NA values, count takes that into consideration.

So if I did

df['A'][1::2] = np.NAN
df.count()

The result would be

 A    3
 B    5

No, there is not something as short as a**b

Here is a simple loop, if you want to avoid doubles:

long result = 1;
for (int i = 1; i <= b; i++) {
   result *= a;
}

If you want to use pow and convert the result in to integer, cast the result as follows:

int result = (int)Math.pow(a, b);

You need to specify the number of rows which should be deleted. In your case (and I assume that you only want to keep one) this can be done like this:

DELETE FROM your_table WHERE id_users=1 AND id_product=2
LIMIT (SELECT COUNT(*)-1 FROM your_table WHERE id_users=1 AND id_product=2)

Hint text not bold, I try to below code.

I am fairly new to Javascript. But this is what I understood: JSON.parse() returns SyntaxError exceptions when invalid JSON is provided as its first parameter. So. It would be better to catch that exception as such like as follows:

try {
    let sData = `
        {
            "id": "1",
            "name": "UbuntuGod",
        }
    `;
    console.log(JSON.parse(sData));
} catch (objError) {
    if (objError instanceof SyntaxError) {
        console.error(objError.name);
    } else {
        console.error(objError.message);
    }
}

The reason why I made the words "first parameter" bold is that JSON.parse() takes a reviver function as its second parameter.

1. Find the right version of your anaconda

2. Put it to ~/.zshrc via command vim ~/.zshrc

   • Anaconda 2 export PATH="/User/<your-username>/anaconda2/bin:$PATH"
   • Anaconda 3 export PATH="/User/<your-username>/anaconda3/bin:$PATH"
   • Or if you install Anaconda in root directory:
   • Anaconda 2 export PATH="/anaconda2/bin:$PATH"
   • Anaconda 3 export PATH="/anaconda3/bin:$PATH"

3. Restart the zsh source ~/.zshrc

In most cases, you shouldn't use a regex for that.

os.path.splitext(filename)[0]

This will also handle a filename like .bashrc correctly by keeping the whole name.

I know you don't want to obfuscate, but maybe you should check out dotfuscator, it will take your compiled assemblies and obfuscate them for you. I think it can even encrypt them.

No, there is no type called "byte" in C++. What you want instead is unsigned char (or, if you need exactly 8 bits, uint8_t from <cstdint>, since C++11). Note that char is not necessarily an accurate alternative, as it means signed char on some compilers and unsigned char on others.

You can also use the following command:

pylint --disable=C0321  test.py

My Pylint version is 0.25.1.

Using urllib, you can get this done instantly.

import urllib.request

opener=urllib.request.build_opener()

urllib.request.install_opener(opener)

urllib.request.urlretrieve(URL, "images/0.jpg")

Update the pom.xml as -

It is pretty obvious that array[10] is faster than array.get(10), as the later internally does the same call, but adds the overhead for the function call plus additional checks.

Modern JITs however will optimize this to a degree, that you rarely have to worry about this, unless you have a very performance critical application and this has been measured to be your bottleneck.

One of the putty tools is pscp.exe; it will allow you to copy files from your remote host.

I have resolve the problem as below 1. Get the tag from your branch 2. Write below command

Example: git branch <Hotfix branch> <TAG>
    git branch hotfix_4.4.3 v4.4.3
    git checkout hotfix_4.4.3

or you can do with other command

git checkout -b <Hotfix branch> <TAG>
-b stands for creating new branch to local 

once you ready with your hotfix branch, It's time to move that branch to github, you can do so by writing below command

git push --set-upstream origin hotfix_4.4.3

It looks like you are trying to use (almost) straight up C code here. Go has a few differences.

• First off, you can't initialize arrays and slices as const. The term const has a different meaning in Go, as it does in C. The list should be defined as var instead.
• Secondly, as a style rule, Go prefers basenameOpts as opposed to basename_opts.
• There is no char type in Go. You probably want byte (or rune if you intend to allow unicode codepoints).
• The declaration of the list must have the assignment operator in this case. E.g.: var x = foo.
• Go's parser requires that each element in a list declaration ends with a comma. This includes the last element. The reason for this is because Go automatically inserts semi-colons where needed. And this requires somewhat stricter syntax in order to work.

For example:

type opt struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}

var basenameOpts = []opt { 
    opt {
        shortnm: 'a', 
        longnm: "multiple", 
        needArg: false, 
        help: "Usage for a",
    },
    opt {
        shortnm: 'b', 
        longnm: "b-option", 
        needArg: false, 
        help: "Usage for b",
    },
}

An alternative is to declare the list with its type and then use an init function to fill it up. This is mostly useful if you intend to use values returned by functions in the data structure. init functions are run when the program is being initialized and are guaranteed to finish before main is executed. You can have multiple init functions in a package, or even in the same source file.

    type opt struct {
        shortnm      byte
        longnm, help string
        needArg      bool
    }

    var basenameOpts []opt

    func init() { 
        basenameOpts = []opt{
            opt {
                shortnm: 'a', 
                longnm: "multiple", 
                needArg: false, 
                help: "Usage for a",
            },
            opt {
                shortnm: 'b', 
                longnm: "b-option", 
                needArg: false, 
               help: "Usage for b",
            },
        }
    }

Since you are new to Go, I strongly recommend reading through the language specification. It is pretty short and very clearly written. It will clear a lot of these little idiosyncrasies up for you.

This occurs if the password for the database is not given.

default="postgres://postgres:[email protected]:5432/DBname"

Place the below lines in your <EditText>:

android:digits="0123456789"
android:inputType="phone"

You could also use the generic function cbind() and lm() without the intercept:

cbind(lm(d$Rate1~-1+d$Name)$coef,lm(d$Rate2~-1+d$Name)$coef)
>               [,1]     [,2]
>d$NameAira 16.33333 47.00000
>d$NameBen  31.33333 50.33333
>d$NameCat  44.66667 54.00000

Execute chmod 777 -R scripts/, it worked fine for me ;)

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

If you want to run your command in parallel for each line you can use GNU Parallel

parallel -a <your file> <program>

Each line of your file will be passed to program as an argument. By default parallel runs as many threads as your CPUs count. But you can specify it with -j

hope it will work

 @Html.DropDownList("accountid", (IEnumerable<SelectListItem>)ViewBag.Accounts, String.Empty, new { @class ="extra-class" })

Here String.Empty will be the empty as a default selector.

Maybe this helps someone:

git tag 0.0.1                    # creates tag locally     
git push origin 0.0.1            # pushes tag to remote

git tag --delete 0.0.1           # deletes tag locally    
git push --delete origin 0.0.1   # deletes remote tag

The following should work. Keep single connection open all time, and just create new commands and execute them.

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (SqlCommand command1 = new SqlCommand(commandText1, connection))
    {
    }
    using (SqlCommand command2 = new SqlCommand(commandText2, connection))
    {
    }
    // etc
}

Starting in NumPy version 1.10, we have the method stack. It can stack arrays of any dimension (all equal):

# List of arrays.
L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]

# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True

M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)

# This are all true    
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

Looks like the solution in the question doesn't work with Django 1.7 anymore and raises an error: "Cannot reorder a query once a slice has been taken"

According to the documentation https://docs.djangoproject.com/en/dev/topics/db/queries/#limiting-querysets forcing the “step” parameter of Python slice syntax evaluates the Query. It works this way:

Model.objects.all().order_by('-id')[:10:1]

Still I wonder if the limit is executed in SQL or Python slices the whole result array returned. There is no good to retrieve huge lists to application memory.

You have to edit httpd.conf and find this line: Listen 127.0.0.1:80

Then write down your desired IP you set for LAN. Don't use automatic IP.
e.g.: Listen 192.168.137.1:80

I used 192.167.137.1 as my LAN IP of Windows 7. Restart Apache and enjoy sharing.

You can try this one it is short :)

SystemClock.sleep(7000);

It will sleep for 7 sec look at documentation

use curl php library: http://php.net/manual/en/book.curl.php

direct example: CURL_EXEC:

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

If you don't need the leading and trailing spaces :

str.Trim().Length

In your case you have a List of Strings and most of the already proposed solutions (I specially like @guyblank answer) are just fine but!!!, if you have a List of beans, which is my case, you can use Comparable interface in your bean like this:

public class UserBean implements Comparable<UserBean> {

   private String name;
   private String surname;        
   private Integer phone;

   // GETTERS AND SETTERS

   public int compareTo(UserBean bean) {
       return name.compareToIgnoreCase(bean.name);
   }

}

Then you only need to create your ArrayList<UserBean> userBeanArray = new ArrayList<UserBean>();, fill it and sort it: Collections.sort(userBeanArray);

And you have it done!

Hope to help to community ;-)

I would make a new image of the dog's silhouette (black) and the rest the same as the original image. In the html, add a wrapper div with this silhouette as as background. Now, make the original image semi-transparent. The dog will become darker and the background of the dog will stay the same. You can do :hover tricks by setting the opacity of the original image to 100% on hover. Then the dog pops out when you mouse over him!

style

.wrapper{background-image:url(silhouette.png);} 
.original{opacity:0.7:}
.original:hover{opacity:1}

<div class="wrapper">
  <div class="img">
    <img src="original.png">
  </div>
</div>

I followed all the answers of this question to change a working legacy code using - Statement ( but having SQL Injections ) to a solution using PreparedStatement with a much slower code because of poor understanding of semantics around Statement.addBatch(String sql) & PreparedStatement.addBatch().

So I am listing my scenario here so others don't make same mistake.

My scenario was

Statement statement = connection.createStatement();

for (Object object : objectList) {
    //Create a query which would be different for each object 
    // Add this query to statement for batch using - statement.addBatch(query);
}
statement.executeBatch();

So in above code , I had thousands of different queries, all added to same statement and this code worked faster because statements not being cached was good & this code executed rarely in the app.

Now to fix SQL Injections, I changed this code to ,

List<PreparedStatement> pStatements = new ArrayList<>();    
for (Object object : objectList) {
    //Create a query which would be different for each object 
    PreparedStatement pStatement =connection.prepareStatement(query);
    // This query can't be added to batch because its a different query so I used list. 
    //Set parameter to pStatement using object 
    pStatements.add(pStatement);
}// Object loop
// In place of statement.executeBatch(); , I had to loop around the list & execute each update separately          
for (PreparedStatement ps : pStatements) {
    ps.executeUpdate();
}

So you see, I started creating thousands of PreparedStatement objects & then eventually not able to utilize batching because my scenario demanded that - there are thousands of UPDATE or INSERT queries & all of these queries happen to be different.

Fixing SQL injection was mandatory at no cost of performance degradation and I don't think that it is possible with PreparedStatement in this scenario.

Also, when you use inbuilt batching facility, you have to worry about closing only one Statement but with this List approach, you need to close statement before reuse , Reusing a PreparedStatement

Yes, it is mainly to anchor your keywords, in particular the location of your page, so whenever URL loads the page with particular anchor name, then it will be pointed to that particular location.

For example, www.something.com/some_page/#computer if it is very lengthy page and you want to show exactly computer then you can anchor.

<p> adfadsf </p>
<p> adfadsf </p>
<p> adfadsf </p>
<a name="computer"></a><p> Computer topics </p>
<p> adfadsf </p>

Now the page will scroll and bring computer-related topics to the top.

getSupportFragmentManager() used when you are in activity and want to get a fragment but in the fragment you can access

getSupportFragmentManager()

by use another method called getFragmentMangaer() works the same like getSupportFragmentManager() and you can use it like you used to:

fragmentTransaction =getFragmentManager().beginTransaction();

Addendum: No one mentioned "Populate" --- it is very much worth your time and money looking at Mongooses Populate Method : Also explains cross documents referencing

The background-image can also be used to create an underline. This method handles line breaks.

It has to be shifted down via background-position and repeated horizontally. The line width can be adjusted to some degree using background-size (the background is limited to the content box of the element).

.underline
{
    --color: green;
    font-size: 40px;
    background-image: linear-gradient(var(--color) 0%, var(--color) 100%);
    background-repeat: repeat-x;
    background-position: 0 1.05em;
    background-size: 2px 5px;
}

<span class="underline">
     Underlined<br/>
     Text
</span>

var list3 = list1.Where(x => !list2.Any(z => z.Id == x.Id)).ToList();

Note: list3 will contain the items or objects that are not in both lists. Note: Its ToList() not toList()

A note about 64bit Windows which seems to trip up a few folks. If your app is running under 64bit Windows, you likely have to set the DWORD under [HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] instead.

Same think can be done using lambda function. Here I am reading the data from a xlsx file.

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

searchfile = open("file.txt", "r")
for line in searchfile:
    if "searchphrase" in line: print line
searchfile.close()

To print out multiple lines (in a simple way)

f = open("file.txt", "r")
searchlines = f.readlines()
f.close()
for i, line in enumerate(searchlines):
    if "searchphrase" in line: 
        for l in searchlines[i:i+3]: print l,
        print

The comma in print l, prevents extra spaces from appearing in the output; the trailing print statement demarcates results from different lines.

Or better yet (stealing back from Mark Ransom):

with open("file.txt", "r") as f:
    searchlines = f.readlines()
for i, line in enumerate(searchlines):
    if "searchphrase" in line: 
        for l in searchlines[i:i+3]: print l,
        print

You are not doing error checking after the call to mysql_query:

$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
if (!$result) { // add this check.
    die('Invalid query: ' . mysql_error());
}

In case mysql_query fails, it returns false, a boolean value. When you pass this to mysql_fetch_array function (which expects a mysql result object) we get this error.

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

A typical way would be to use stringstream:

#include <iomanip>
#include <sstream>

double pi = 3.14159265359;
std::stringstream stream;
stream << std::fixed << std::setprecision(2) << pi;
std::string s = stream.str();

See fixed

Use fixed floating-point notation

Sets the floatfield format flag for the str stream to fixed.

When floatfield is set to fixed, floating-point values are written using fixed-point notation: the value is represented with exactly as many digits in the decimal part as specified by the precision field (precision) and with no exponent part.

and setprecision.

For conversions of technical purpose, like storing data in XML or JSON file, C++17 defines to_chars family of functions.

Assuming a compliant compiler (which we lack at the time of writing), something like this can be considered:

#include <array>
#include <charconv>

double pi = 3.14159265359;
std::array<char, 128> buffer;
auto [ptr, ec] = std::to_chars(buffer.data(), buffer.data() + buffer.size(), pi,
                               std::chars_format::fixed, 2);
if (ec == std::errc{}) {
    std::string s(buffer.data(), ptr);
    // ....
}
else {
    // error handling
}

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

To add to Timo's answer LINQ can be used like this as well:

items = items.Select(i => {

     ...
     //perform some logic adding / updating.

     return i / return new Item();
     ...

     //To remove an item simply have logic to return null.

     //Then attach the Where to filter out nulls

     return null;
     ...


}).Where(i => i != null);

Could you try this one:

create or replace 
procedure point_triangle
IS
BEGIN
  FOR thisteam in (select P.FIRSTNAME,P.LASTNAME, SUM(P.PTS) S from PLAYERREGULARSEASON P  where P.TEAM = 'IND'  group by P.FIRSTNAME, P.LASTNAME order by SUM(P.PTS) DESC)
  LOOP
    dbms_output.put_line(thisteam.FIRSTNAME|| ' ' || thisteam.LASTNAME  || ':' || thisteam.S);
  END LOOP;

END;

How about this? I frequently use the CSS Flexible Box Layout to center something.

<div style="display: flex; justify-content: center;">_x000D_
  <img src="http://icons.iconarchive.com/icons/rokey/popo-emotions/128/big-smile-icon.png" style="width: 40px; height: 40px;" />_x000D_
</div>

Alternately, you can start a program containing the line with one click.

Just select the method stub for it when creating the new Java class, where the code says,

Which method stubs would you like to create?

[check-box] public static void main(String[]args) <---- Select this one.

[check-box] Constructors from superclass

[check-box] Inherited abstract methods

Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.

I had this problem but didn't have a version conflict in my package.json.

My package-lock.json was somehow out of sync with package json though. Deleting and regenerating it worked for me.

While inserting the data, we have to used character string delimiter (' '). And, you missed it (' ') while inserting values which is the reason of your error message. The correction of code is given below:

INSERT INTO LOCATION VALUES(PQ95VM,'HAPPY_STREET','FRANCE');

To see the file size of your containers, you can use the --size argument of docker ps:

docker ps --size

To complement @tyczj answer:

 @Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    onSet(mList.get(position), (K) holder);

}

public abstract void onSet(T item, K holder);

}

ViewHolder:

public class Holders  {

    public static class TextImageHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

        public TextView text;

        public TextImageHolder(View itemView) {
            super(itemView);
            text = (TextView) itemView.findViewById(R.id.text);
            text.setOnClickListener(this);


        }

        @Override
        public void onClick(View v) {

        }
    }


}

Adapter usage:

public class CategoriesAdapter extends GenericRecycleAdapter<Category, Holders.TextImageHolder> {


    public CategoriesAdapter(List<Category> list, Context context) {
        super(list, context);
    }

    @Override
    void onItem(Category category) {

    }


    @Override
    public int getLayout() {
        return R.layout.categories_row;
    }

    @Override
    public void onSet(Category item, Holders.TextImageHolder holder) {

    }



}

C99 standard on c >= '0' && c <= '9'

c >= '0' && c <= '9' (mentioned in another answer) works because C99 N1256 standard draft 5.2.1 "Character sets" says:

In both the source and execution basic character sets, the value of each character after 0 in the above list of decimal digits shall be one greater than the value of the previous.

ASCII is not guaranteed however.

simple example of a function parent_by_selector which return a parent or null (no selector matches):

function parent_by_selector(node, selector, stop_selector = 'body') {
  var parent = node.parentNode;
  while (true) {
    if (parent.matches(stop_selector)) break;
    if (parent.matches(selector)) break;
    parent = parent.parentNode; // get upper parent and check again
  }
  if (parent.matches(stop_selector)) parent = null; // when parent is a tag 'body' -> parent not found
  return parent;
};

If nothing works then add authentication mode="Windows" in your system.web attribute in your Web.Config file. hope it will work for you.

$(document).on('change','#multiid',function(){
  // you desired code 
});

You should probably check for errors in /var/log/nginx/error.log.

In my case I did no add the port for ipv6. You should also do this (in case you are running nginx on a port other than 80): listen [::]:8000 default_server ipv6only=on;

Do you mean something like this:

s1 = '00000001'
s2 = '11111110'
int(s1,2) ^ int(s2,2)

Remove the if keyword. It should just be predicate ? true_result : false_result.

Also ? : is called ternary operator.

but I can't initialize my derived class, I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ?? so I'm thinking maybe in the PetStore default constructor I can call Farm()... so any Idea ???

Don't panic.

Farm constructor will be called in the constructor of PetStore, automatically.

See the base class inheritance calling rules: What are the rules for calling the superclass constructor?

If you are splitting a string in Lua, you should try the string.gmatch() or string.sub() methods. Use the string.sub() method if you know the index you wish to split the string at, or use the string.gmatch() if you will parse the string to find the location to split the string at.

Example using string.gmatch() from Lua 5.1 Reference Manual:

 t = {}
 s = "from=world, to=Lua"
 for k, v in string.gmatch(s, "(%w+)=(%w+)") do
   t[k] = v
 end

I am guessing there is a fundamental reason for the change, it isn't merely cosmetic to make the old interpretation clearer: that reason is concurrency. Unspecified order of elaboration is merely selection of one of several possible serial orderings, this is quite different to before and after orderings, because if there is no specified ordering, concurrent evaluation is possible: not so with the old rules. For example in:

f (a,b)

previously either a then b, or, b then a. Now, a and b can be evaluated with instructions interleaved or even on different cores.

The above answers may help you but you may also want to know how to use array of function pointers.

void fun1()
{

}

void fun2()
{

}

void fun3()
{

}

void (*func_ptr[3])() = {fun1, fun2, fun3};

main()
{
    int option;


    printf("\nEnter function number you want");
    printf("\nYou should not enter other than 0 , 1, 2"); /* because we have only 3 functions */
    scanf("%d",&option);

    if((option>=0)&&(option<=2))
    { 
        (*func_ptr[option])();
    }

    return 0;
}

You can only assign the addresses of functions with the same return type and same argument types and no of arguments to a single function pointer array.

You can also pass arguments like below if all the above functions are having the same number of arguments of same type.

  (*func_ptr[option])(argu1);

Note: here in the array the numbering of the function pointers will be starting from 0 same as in general arrays. So in above example fun1 can be called if option=0, fun2 can be called if option=1 and fun3 can be called if option=2.

For example, if you want to replace search1 with replace1 and search2 with replace2 then following code will work:

print str_replace(
    array("search1","search2"),
    array("replace1", "replace2"),
    "search1 search2"
);

// Output: replace1 replace2

Your can use NumPy's array indexing:

def unison_shuffled_copies(a, b):
    assert len(a) == len(b)
    p = numpy.random.permutation(len(a))
    return a[p], b[p]

This will result in creation of separate unison-shuffled arrays.

After a quick google:

__STDC__ and __STDC_VERSION__, see here

Try this jsfiddle. This is using jQuery and made from Hashem Qolami's answer. At first, make a regular table then make it scrollable.

const makeScrollableTable = function (tableSelector, tbodyHeight) {
  let $table = $(tableSelector);
  let $bodyCells = $table.find('tbody tr:first').children();
  let $headCells = $table.find('thead tr:first').children();
  let headColWidth = 0;
  let bodyColWidth = 0;
  
  headColWidth = $headCells.map(function () {
    return $(this).outerWidth();
  }).get();
  bodyColWidth = $bodyCells.map(function () {
    return $(this).outerWidth();
  }).get();

  $table.find('thead tr').children().each(function (i, v) {
    $(v).css("width", headColWidth[i]+"px");
    $(v).css("min-width", headColWidth[i]+"px");
    $(v).css("max-width", headColWidth[i]+"px");
  });
  $table.find('tbody tr').children().each(function (i, v) {
    $(v).css("width", bodyColWidth[i]+"px");
    $(v).css("min-width", bodyColWidth[i]+"px");
    $(v).css("max-width", bodyColWidth[i]+"px");
  });

  $table.find('thead').css("display", "block");
  $table.find('tbody').css("display", "block");

  $table.find('tbody').css("height", tbodyHeight+"px");
  $table.find('tbody').css("overflow-y", "auto");
  $table.find('tbody').css("overflow-x", "hidden");
  
};

Then you can use this function as follows:

makeScrollableTable('#test-table', 250);

I've never actually used this, but try view.getClass().getGenericSuperclass()

So is there any other method to achieve this goal?

No. In order to convert an image to a byte array you have to specify an image format - just as you have to specify an encoding when you convert text to a byte array.

If you're worried about compression artefacts, pick a lossless format. If you're worried about CPU resources, pick a format which doesn't bother compressing - just raw ARGB pixels, for example. But of course that will lead to a larger byte array.

Note that if you pick a format which does include compression, there's no point in then compressing the byte array afterwards - it's almost certain to have no beneficial effect.

string.find("substring") will help you. This function returns -1 when there is no substring.

I had such problem. Solution was simple :

1. Install python 2.7 64bit version.
2. Export HKEY_LOCAL_MACHINE\SOFTWARE\Python.
3. Remove Python 2.7.
4. insert exported reg file.
5. rename all C:\Python27 to C:\Anaconda ( insert your path ).

P.S. Sorry, for bad grammar.

Modify the maximun memory parameter in eclipse.ini

-Xmx1024m

And restart your computer.

It worked for me :)

FormsModule should be added at imports array not declarations array.

• imports array is for importing modules such as BrowserModule, FormsModule, HttpModule
• declarations array is for your Components, Pipes, Directives

refer below change:

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})

After searching a bit about the method to open the existing sheet in xlxs, i discovered

existingWorksheet = wb.get_worksheet_by_name('Your Worksheet name goes here...')
existingWorksheet.write_row(0,0,'xyz')

You can now append/write any data to the open worksheet. I hope it helps. Thanks

See if this is what you want to do:

@echo off
for /f "delims=" %%a in ('wmic OS Get localdatetime  ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set HH=%dt:~8,2%
set Min=%dt:~10,2%
set Sec=%dt:~12,2%

set stamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%

copy "F:\Folder\File 1.xlsx" "F:\Folder\Archive\File 1 - %stamp%.xlsx"

You can follow these steps to remove all the files associated with virtualenv and then reinstall the virtualenv again and using it

cd {python virtualenv folder}

find {broken virtualenv}/ -type l                             ## to list out all the links

deactivate                                           ## deactivate if virtualenv is active

find {broken virtualenv}/ -type l -delete                    ## to delete the broken links

virtualenv {broken virtualenv} --python=python3           ## recreate links to OS's python

workon {broken virtualenv}                       ## activate & workon the fixed virtualenv

pip3 install  ... {other packages required for the project}

The Interface javax.servlet.http.HttpServletResponse from the servlet API has all the response codes in the form of int constants names SC_<description>. See http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletResponse.html

This is the easiest way I can figure out:

#!/usr/bin/python3
for i in range(97, 123):
    print("{:c}".format(i), end='')

So, 97 to 122 are the ASCII number equivalent to 'a' to and 'z'. Notice the lowercase and the need to put 123, since it will not be included).

In print function make sure to set the {:c} (character) format, and, in this case, we want it to print it all together not even letting a new line at the end, so end=''would do the job.

The result is this: abcdefghijklmnopqrstuvwxyz

In that case you should use ListBox control instead of dropdown and Set the SelectionMode property to Multiple

<asp:ListBox runat="server" SelectionMode="Multiple" >
  <asp:ListItem Text="test1"></asp:ListItem>
  <asp:ListItem Text="test2"></asp:ListItem>
  <asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>

More information will be useful.

When I was faced with the same error message all I had to do was to correctly configure the credentials page of the DataSource(I am using Report Builder 3). if you chose the default, the report would work fine in Report Builder but would fail on the Report Server.

You may review more details of this fix here: https://hodentekmsss.blogspot.com/2017/05/fix-for-rserroropeningconnection-in.html

Or you can split your string to string array, splitting by space and then add every item of string array to empty string.
May be this is not the best and fastest method, but you can try, if other answer aren't what you whant.

For array type Please try this one.

 List<MyStok> myDeserializedObjList = (List<MyStok>)Newtonsoft.Json.JsonConvert.DeserializeObject(sc), typeof(List<MyStok>));

Please See here for details to deserialise Json

shortest way to do it is:

git pull --rebase --autostash

If you used Create React App, you can set an environment variable using a .env file. The documentation is here:

https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables

Basically do something like this in the .env file at the project root.

REACT_APP_NOT_SECRET_CODE=abcdef

Note that the variable name must start with REACT_APP_

You can access it from your component with

process.env.REACT_APP_NOT_SECRET_CODE

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

You can multiply it by 10 and then do a "modulo" operation/divison with 10, and check if result of that two operations is zero. Result of that two operations will give you first digit after the decimal point. If result is equal to zero then the number is a whole number.

if ( (int)(number * 10.0) % 10 == 0 ){
// your code
}

Additionally to IIDan's answer: For some purposes it is necessary to set

label.layer.shouldRasterize = YES

I think this is due to the blend mode that is used to render the shadow. For example I had a dark background and white text on it and wanted to "highlight" the text using a black shadowy glow. It wasn't working until I set this property.

You are comparing two objects for equality. The snippet:

if (obj == this) {     return true; } 

is a quick test that can be read

"If the object I'm comparing myself to is me, return true"

. You usually see this happen in equals methods so they can exit early and avoid other costly comparisons.

How about

if value in my_array[:, col_num]:
    do_whatever

Edit: I think __contains__ is implemented in such a way that this is the same as @detly's version

You can configure the connect body parser middleware in a configuration block in your main application file:

    /** Form Handling */
    app.use(express.bodyParser({
        uploadDir: '/tmp/uploads',
        keepExtensions: true
    }))
    app.use(express.limit('5mb'));

In my experience, this turned out to be the most efficient

driver.find_element_by_css_selector('foo').send_keys(u'\ue009' + u'\ue003')

We are sending Ctrl + Backspace to delete all characters from the input, you can also replace backspace with delete.

EDIT: removed Keys dependency

As ben foster says you can return the Javascripts and it will redirect you to the desired page.

To load page in the current page:

return JavaScript("window.location = 'http://www.google.co.uk'");'

To load page in the new tab:

return JavaScript("window.open('http://www.google.co.uk')");

Wireshark does not do port redirection, but sniffs and interprets a lot of protocols.

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] >= 3:
    from urllib.request import urlretrieve
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlretrieve

# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

You can use Path API as follow:

 var filenNme = Path.GetFileNameWithoutExtension([File Path]);

More info: Path.GetFileNameWithoutExtension

Using flexbox

   #parent_div_1{
     display:flex;
     flex-wrap: wrap;
  }

From linux/typecheck.h:

/*
 * Check at compile time that something is of a particular type.
 * Always evaluates to 1 so you may use it easily in comparisons.
 */
#define typecheck(type,x) \
({  type __dummy; \
    typeof(x) __dummy2; \
    (void)(&__dummy == &__dummy2); \
    1; \
})

Here you can find explanation which statements from standard and which GNU extensions above code uses.

(Maybe a bit not in scope of the question, since question is not about failure on type mismatch, but anyway, leaving it here).

In addition from the command prompt run SET.

This displayed the "LOGONSERVER" value which indicates the specific domain controller you are using (there can be more than one).

Then you got to that server's NetBios Share \Servername\SYSVOL\domain.local\scripts.

You have two span6 divs within your row so that will take up the whole 12 spans that a row is made up of.

Adding pull-right to the second span6 div isn't going to do anything to it as it's already sitting to the right.

If you mean you want to have the text in the second span6 div aligned to the right then simple add a new class to that div and give it the text-align: right value e.g.

.myclass {
    text-align: right;
}

UPDATE:

EricFreese pointed out that in the 2.3 release of Bootstrap (last week) they've added text-align utility classes that you can use:

• .text-left
• .text-center
• .text-right

Your problem is that you are naming your component class Date. When you call new Date() within your class, it won't create an instance of the Date you expect it to create (which is likely this Date)- it will try to create an instance of your component class. Then the constructor will try to create another instance, and another instance, and another instance... Until you run out of stack space and get the error you're seeing.

If you want to use Date within your class, try naming your class something different such as Calendar or DateComponent.

The reason for this is how JavaScript deals with name scope: Whenever you create a new named entity, if there is already an entity with that name in scope, that name will stop referring to the previous entity and start referring to your new entity. So if you use the name Date within a class named Date, the name Date will refer to that class and not to any object named Date which existed before the class definition started.

I met the same issue while experimenting with my own Python library and what I've found out is that pip freeze will show you the library as installed if your current directory contains lib.egg-info folder. And pip uninstall <lib> will give you the same error message.

1. Make sure your current directory doesn't have any egg-info folders
2. Check pip show <lib-name> to see the details about the location of the library, so you can remove files manually.

For a direct scroll:

getListView().setSelection(21);

For a smooth scroll:

getListView().smoothScrollToPosition(21);

Another js alternative:

Working Example

fontsize = function () {
    var fontSize = $("#container").width() * 0.10; // 10% of container width
    $("#container h1").css('font-size', fontSize);
};
$(window).resize(fontsize);
$(document).ready(fontsize);

Or as stated in torazaburo's answer you could use svg. I put together a simple example as a proof of concept:

SVG Example

<div id="container">
    <svg width="100%" height="100%" viewBox="0 0 13 15">
        <text x="0" y="13">X</text>
    </svg>
</div>

I've changed the recursion to iteration.

Works good :D

# 10GB

# check the current size

CHECK=${CHECK%G*}
echo "Current Foldersize: $CHECK GB"

if (( $(echo "$CHECK > $SIZE" |bc -l) )); then
        echo "Folder is bigger than $SIZE GB"
else
        echo "Folder is smaller than $SIZE GB"

Could you also increase post_max_size and see if it helps?

Uploading a file through an HTML form makes the upload treated like any other form element content, that's why increasing post_max_size should be required too.

Update : the final solution involved the command-line:

To export only 1 table you would do

mysqldump -u user_name -p your_password your_database_name your_table_name > dump_file.sql

and to import :

mysql -u your_user -p your_database < dump_file.sql 

'drop table your_tabe_name;' can also be added at the top of the import script if it's not already there, to ensure the table gets deleted before the script creates and fill it

Use the package plyr with lapply to get frequencies for every value (level) and every variable (factor) in your data frame.

library(plyr)
lapply(df, count)

I've used Xavier's answer quite a bit. I want to add that restricting the package version to a specified range is easy and useful in the latest versions of NuGet.

For example, if you never want Newtonsoft.Json to be updated past version 3.x.x in your project, change the corresponding package element in your packages.config file to look like this:

<package id="Newtonsoft.Json" version="3.5.8" allowedVersions="[3.0, 4.0)" targetFramework="net40" />

Notice the allowedVersions attribute. This will limit the version of that package to versions between 3.0 (inclusive) and 4.0 (exclusive). Then, when you do an Update-Package on the whole solution, you don't need to worry about that particular package being updated past version 3.x.x.

The documentation for this functionality is here.

• OR is spelled should
• AND is spelled must
• NOR is spelled should_not

Example:

You want to see all the items that are (round AND (red OR blue)):

{
    "query": {
        "bool": {
            "must": [
                {
                    "term": {"shape": "round"}
                },
                {
                    "bool": {
                        "should": [
                            {"term": {"color": "red"}},
                            {"term": {"color": "blue"}}
                        ]
                    }
                }
            ]
        }
    }
}

You can also do more complex versions of OR, for example if you want to match at least 3 out of 5, you can specify 5 options under "should" and set a "minimum_should" of 3.

Thanks to Glen Thompson and Sebastialonso for finding where my nesting wasn't quite right before.

Thanks also to Fatmajk for pointing out that "term" becomes "match" in ElasticSearch 6.

This is speculation, but based on Google's reference to the "risk analysis engine" they use (http://googleonlinesecurity.blogspot.com/2014/12/are-you-robot-introducing-no-captcha.html)

I would assume it looks at how you behaved prior to clicking, how your cursor moved on its way to the check (organic path/acceleration), which part of the checkbox was clicked (random places, or dead on center every time), browser fingerprint, Google cookies & contents, click location history tied to your fingerprint or account if it detects one etc.

It's fairly difficult to fake "organic" behavior in such a way that it would fool a continuously learning pattern detection engine. In the cases where it's not sure, it still prompts you to match an actual CAPTCHA string.

In my case, when I created the web form, it was named as WebForm1.aspx and respective names (WebForm1). Letter, I renamed that to something else. I renamed manually at almost all the places, but one place in designer file was still showing it as 'WebForm1'.

I changed that too and got rid of this error.

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.

The one with the "Pings" helped me... but may be explained a little better...

For me the solution was to change:

copy $(TargetDir)$(TargetName).* $(SolutionDir)bin

to this:

copy "$(TargetDir)$(TargetName).*" "$(SolutionDir)bin"

Hope it works for you. :-)

I had the same error message. In my case I had inadvertently mixed the ES6 export default function myFunc syntax with const myFunc = require('./myFunc');.

Using module.exports = myFunc; instead solved the issue.

summation and your other functions are defined after they're used in main, and so the compiler has made a guess about it's signature; in other words, an implicit declaration has been assumed.

You should declare the function before it's used and get rid of the warning. In the C99 specification, this is an error.

Either move the function bodies before main, or include method signatures before main, e.g.:

#include <stdio.h>

int summation(int *, int *, int *);

int main()
{
    // ...

If you're dealing with character encodings other than UTF-16, you shouldn't be using java.lang.String or the char primitive -- you should only be using byte[] arrays or ByteBuffer objects. Then, you can use java.nio.charset.Charset to convert between encodings:

Charset utf8charset = Charset.forName("UTF-8");
Charset iso88591charset = Charset.forName("ISO-8859-1");

ByteBuffer inputBuffer = ByteBuffer.wrap(new byte[]{(byte)0xC3, (byte)0xA2});

// decode UTF-8
CharBuffer data = utf8charset.decode(inputBuffer);

// encode ISO-8559-1
ByteBuffer outputBuffer = iso88591charset.encode(data);
byte[] outputData = outputBuffer.array();

In your windows os follow the following steps:

1)search services 2)Find Apache tomcat 3)Right-click on it and select end 4)Run your spring boot application again it will work

The proper way to sort strings is:

import locale
locale.setlocale(locale.LC_ALL, 'en_US.UTF-8') # vary depending on your lang/locale
assert sorted((u'Ab', u'ad', u'aa'), cmp=locale.strcoll) == [u'aa', u'Ab', u'ad']

# Without using locale.strcoll you get:
assert sorted((u'Ab', u'ad', u'aa')) == [u'Ab', u'aa', u'ad']

The previous example of mylist.sort(key=lambda x: x.lower()) will work fine for ASCII-only contexts.

You can use:

WITH index = ...

In curl version 7.22.0 on Ubuntu and 7.24.0 on OSX the solution to not show progress but to show errors is to use both -s (--silent) and -S (--show-error) like so:

curl -sS http://google.com > temp.html

This works for both redirected output > /some/file, piped output | less and outputting directly to the terminal for me.

Update: Since curl 7.67.0 there is a new option --no-progress-meter which does precisely this and nothing else, see clonejo's answer for more details.
