You have also a very good testing frameworks to create such a stub. One of my preferrable is Mockito There is also EasyMock and others... But Mockito is great you should read it - very elegant and powerfull package

A Stub is an object that implements an interface of a component, but instead of returning what the component would return when called, the stub can be configured to return a value that suits the test. Using stubs a unit test can test if a unit can handle various return values from its collaborator. Using a stub instead of a real collaborator in a unit test could be expressed like this:

unit test --> stub

unit test --> unit --> stub

unit test asserts on results and state of unit

First the unit test creates the stub and configures its return values. Then the unit test creates the unit and sets the stub on it. Now the unit test calls the unit which in turn calls the stub. Finally the unit test makes assertions about the results of the method calls on the unit.

A Mock is like a stub, only it also has methods that make it possible determine what methods where called on the Mock. Using a mock it is thus possible to both test if the unit can handle various return values correctly, and also if the unit uses the collaborator correctly. For instance, you cannot see by the value returned from a dao object whether the data was read from the database using a Statement or a PreparedStatement. Nor can you see if the connection.close() method was called before returning the value. This is possible with mocks. In other words, mocks makes it possible to test a units complete interaction with a collaborator. Not just the collaborator methods that return values used by the unit. Using a mock in a unit test could be expressed like this:

unit test --> mock

unit test --> unit --> mock

unit test asserts on result and state of unit

unit test asserts on the methods called on mock

The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of:

• a) The IP/domain or port is incorrect
• b) The IP/domain or port (i.e service) is down
• c) The IP/domain is taking longer than your default timeout to respond
• d) You have a firewall that is blocking requests or responses on whatever port you are using
• e) You have a firewall that is blocking requests to that particular host
• f) Your internet access is down

Note that firewalls and port or IP blocking may be in place by your ISP

http://www.digizol.com/2008/09/eclipse-access-restriction-on-library.html worked best for me.

On Windows: Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rules): -> change to warning

On Mac OS X/Linux: Eclipse -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rules): -> change to warning

If your set command supports the /p switch, then you can pipe input that way.

set /p VAR1=<test.txt
set /? |find "/P"

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

This has the added benefit of working for un-registered file types (which the accepted answer does not).

Any way to do this without manually re-installing the packages in a new virtualenv to get their dependencies ? This would be error-prone and I'd like to automate the process of cleaning the virtualenv from no-longer-needed old dependencies.

That's what pip-tools package is for (from https://github.com/jazzband/pip-tools):

Installation

$ pip install --upgrade pip  # pip-tools needs pip==6.1 or higher (!)
$ pip install pip-tools

Example usage for pip-compile

Suppose you have a Flask project, and want to pin it for production. Write the following line to a file:

# requirements.in
Flask

Now, run pip-compile requirements.in:

$ pip-compile requirements.in
#
# This file is autogenerated by pip-compile
# Make changes in requirements.in, then run this to update:
#
#    pip-compile requirements.in
#
flask==0.10.1
itsdangerous==0.24        # via flask
jinja2==2.7.3             # via flask
markupsafe==0.23          # via jinja2
werkzeug==0.10.4          # via flask

And it will produce your requirements.txt, with all the Flask dependencies (and all underlying dependencies) pinned. Put this file under version control as well and periodically re-run pip-compile to update the packages.

Example usage for pip-sync

Now that you have a requirements.txt, you can use pip-sync to update your virtual env to reflect exactly what's in there. Note: this will install/upgrade/uninstall everything necessary to match the requirements.txt contents.

$ pip-sync

You might like the function GetInfoFromClosedFile()

Edit: Since the above link does not seem to work anymore, I am adding alternate link 1 and alternate link 2 + code:

Private Function GetInfoFromClosedFile(ByVal wbPath As String, _
    wbName As String, wsName As String, cellRef As String) As Variant
Dim arg As String
    GetInfoFromClosedFile = ""
    If Right(wbPath, 1) <> "" Then wbPath = wbPath & ""
    If Dir(wbPath & "" & wbName) = "" Then Exit Function
    arg = "'" & wbPath & "[" & wbName & "]" & _
        wsName & "'!" & Range(cellRef).Address(True, True, xlR1C1)
    On Error Resume Next
    GetInfoFromClosedFile = ExecuteExcel4Macro(arg)
End Function

The PATH solution has the issue that if $(npm bin) is placed in your .profile/.bashrc/etc it is evaluated once and is forever set to whichever directory the path was first evaluated in. If instead you modify the current path then every time you run the script your path will grow.

To get around these issues, I create a function and used that. It doesn't modify your environment and is simple to use:

function npm-exec {
   $(npm bin)/$@  
}

This can then be used like this without making any changes to your environment:

npm-exec r.js <args>

Iterate over the Array. First initialize the maximum value to the first element of the array and then for each element optimize it if the element under consideration is greater.

You call writer.close(); in writeToFile so the writer has been closed the second time you call writeToFile.

Why don't you merge FileStatus into writeToFile?

You can try something like this I guess:

new_str = ""
str_value = "rojbasr"
for i in str_value:
    new_str += "0x%s " % (i.encode('hex'))
print new_str

Your output would be something like this:

0x72 0x6f 0x6a 0x62 0x61 0x73 0x72

if the project is not a big ,

1- change the name of folder project

2- make a new project with the same project (before renaming)

3- add existing files from the old project to the new project (totally same , same folders , same names , ...)

4- open the the new project file (as xml ) and the old project

5- copy the new project file (xml content ) and paste it in the old project file

6- delete the old project

7- rename the old folder project to old name

This post is for Sublime 3.

I just installed Sublime 3, the 64 bit version, on Ubuntu 14.04. I can't tell the difference between this version and Sublime 2 as far as user interface. The reason I didn't go with Sublime 2 is that it gives an annoying "GLib critical" error messages.

Anyways - previous posts mentioned the file /sublime_text_3/Packages/Color\ Scheme\ -\ Default.sublime-package

I wanted to give two tips here with respect to this file in Sublime 3:

1. You can edit it with pico and use ^W to search the theme name. The first search result will bring you to an XML style entry where you can change the values. Make a copy before you experiment.
2. If you choose the theme in the sublime menu (under Preferences/Color Scheme) before you change this file, then the changes will be cached and your change will not take effect. So delete the cached version and restart sublime for the changes to take effect. The cached version is at ~/.config/sublime-text-3/Cache/Color Scheme - Default/

edit 2018: This is outdated, js and typescript now have for..of loops.
http://www.typescriptlang.org/docs/handbook/iterators-and-generators.html

The book "TypeScript Revealed" says

"You can iterate through the items in an array by using either for or for..in loops as demonstrated here:

// standard for loop
for (var i = 0; i < actors.length; i++)
{
  console.log(actors[i]);
}

// for..in loop
for (var actor in actors)
{
  console.log(actor);
}

"

Turns out, the second loop does not pass the actors in the loop. So would say this is plain wrong. Sadly it is as above, loops are untouched by typescript.

map and forEach often help me and are due to typescripts enhancements on function definitions more approachable, lke at the very moment:

this.notes = arr.map(state => new Note(state));

My wish list to TypeScript;

1. Generic collections
2. Iterators (IEnumerable, IEnumerator interfaces would be best)

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bin directory so if you want to change to the default zsh then you would use the following

chsh -s /bin/zsh

If you're using different version of zsh then you might have to add that version to /etc/shells to avoid the nonstandard shell message. For example if you want home-brew's version of zsh then you have to add /usr/local/bin/zsh to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" and then run

chsh -s /usr/local/bin/zsh

Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed

sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh

You can use the fgets() function to read the file line by line:

$handle = fopen("inputfile.txt", "r");
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // process the line read.
    }

    fclose($handle);
} else {
    // error opening the file.
} 

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

In my project, I usually use this snippets:

var type[];
$("input[name='messageCheckbox']:checked").each(function (i) {
                type[i] = $(this).val();
            });

And it works well.

Simple solution without adding observer notification

-(void)setViewMovedUp:(BOOL)movedUp
{
    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.3]; // if you want to slide up the view

    CGRect rect = self.view.frame;

    if (movedUp)
    {
        // 1. move the view's origin up so that the text field that will be hidden come above the keyboard
        // 2. increase the size of the view so that the area behind the keyboard is covered up.
        rect.origin.y -= kOFFSET_FOR_KEYBOARD;
        rect.size.height += kOFFSET_FOR_KEYBOARD;
    }
    else
    {
        // revert back to the normal state.
        rect.origin.y += kOFFSET_FOR_KEYBOARD;
        rect.size.height -= kOFFSET_FOR_KEYBOARD;
    }
    self.view.frame = rect;

    [UIView commitAnimations];
}


-(void)textFieldDidEndEditing:(UITextField *)sender
{
     if  (self.view.frame.origin.y >= 0)
        {
            [self setViewMovedUp:NO];
        }
}

-(void)textFieldDidBeginEditing:(UITextField *)sender
{
        //move the main view, so that the keyboard does not hide it.
        if  (self.view.frame.origin.y >= 0)
        {
            [self setViewMovedUp:YES];
        }
}

Where

#define kOFFSET_FOR_KEYBOARD 80.0

I don't know whether a direct way of doing this is available or not, but you surely there is a workaround via code: listen for onFocus event of EditText, and as soon it gains focus, set the hint to be nothing with something like editText.setHint(""):

This may not be exactly what you have to do, but it may be something like this-

myEditText.setOnFocusListener(new OnFocusListener(){
  public void onFocus(){
    myEditText.setHint("");
  }
});

function search($array, $key, $value) 
{ 
    $results = array(); 

    if (is_array($array)) 
    { 
        if (isset($array[$key]) && $array[$key] == $value) 
            $results[] = $array; 

        foreach ($array as $subarray) 
            $results = array_merge($results, search($subarray, $key, $value)); 
    } 

    return $results; 
} 

To do it with jQuery:

$("#txtSearch").on("keyup", function (event) {
    if (event.keyCode==13) {
        $("#btnSearch").get(0).click();
    }
});

To do it with normal JavaScript:

document.getElementById("txtSearch").addEventListener("keyup", function (event) {
    if (event.keyCode==13) { 
        document.getElementById("#btnSearch").click();
    }
});

You may consider 3rd party tool that called Excel Jetcell .NET component for read/write excel files:

C# sample

// Create New Excel Workbook
ExcelWorkbook Wbook = new ExcelWorkbook();
ExcelCellCollection Cells = Wbook.Worksheets.Add("Sheet1").Cells;

Cells["A1"].Value = "Excel writer example (C#)";
Cells["A1"].Style.Font.Bold = true;
Cells["B1"].Value = "=550 + 5";

// Write Excel XLS file
Wbook.WriteXLS("excel_net.xls");

VB.NET sample

' Create New Excel Workbook
Dim Wbook As ExcelWorkbook = New ExcelWorkbook()
Dim Cells As ExcelCellCollection = Wbook.Worksheets.Add("Sheet1").Cells

Cells("A1").Value = "Excel writer example (C#)"
Cells("A1").Style.Font.Bold = True
Cells("B1").Value = "=550 + 5"

' Write Excel XLS file
Wbook.WriteXLS("excel_net.xls")

Here I present what I believe to be a cross-platform (Linux and macOS at least) solution to the answer that is working well for me currently.

crosspath()
{
    local ref="$1"
    if [ -x "$(which realpath)" ]; then
        path="$(realpath "$ref")"
    else
        path="$(readlink -f "$ref" 2> /dev/null)"
        if [ $? -gt 0 ]; then
            if [ -x "$(which readlink)" ]; then
                if [ ! -z "$(readlink "$ref")" ]; then
                    ref="$(readlink "$ref")"
                fi
            else
                echo "realpath and readlink not available. The following may not be the final path." 1>&2
            fi
            if [ -d "$ref" ]; then
                path="$(cd "$ref"; pwd -P)"
            else
                path="$(cd $(dirname "$ref"); pwd -P)/$(basename "$ref")"
            fi
        fi
    fi
    echo "$path"
}

Here is a macOS (only?) solution. Possibly better suited to the original question.

mac_realpath()
{
    local ref="$1"
    if [[ ! -z "$(readlink "$ref")" ]]; then
        ref="$(readlink "$1")"
    fi
    if [[ -d "$ref" ]]; then
        echo "$(cd "$ref"; pwd -P)"
    else
        echo "$(cd $(dirname "$ref"); pwd -P)/$(basename "$ref")"
    fi
}

You can also use @hourly instant of 0 * * * *

To add to MattDMo's answer, you can get the exact font that's used on Linux like so (the example is from Xubuntu 14.04):

$ fc-match Monospace
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"

You can't get any better than that.

After all, any solution will have to read the entire file, figure out how many \n you have, and return that result.

Do you have a better way of doing that without reading the entire file? Not sure... The best solution will always be I/O-bound, best you can do is make sure you don't use unnecessary memory, but it looks like you have that covered.

You are giving multiple Content-Type headers. application/vnd.ms-excel is enough.

And there are couple of syntax error too. To statement termination with ; on the echo statement and wrong filename extension.

header("Content-Type:   application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=abc.xls");  //File name extension was wrong
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
echo "Some Text"; //no ending ; here

I fix it by delete all index export file, include pipe, service. then all file import path is specific path. eg.

import { AuthService } from './_common/services/auth.service';

replace

import { AuthService } from './_common/services';

besides, don't export default class.

This might work for you (GNU sed):

sed -ri  '/\s+$/s///' file

This looks for whitespace at the end of the line and and if present removes it.

I get the same problem. I have used 10hrs to findout.

https://serverless.com/framework/docs/providers/aws/events/apigateway/

// handler.js

'use strict';

module.exports.hello = function(event, context, callback) {

const response = {
  statusCode: 200,
  headers: {
    "Access-Control-Allow-Origin" : "*", // Required for CORS support to work
    "Access-Control-Allow-Credentials" : true // Required for cookies, authorization headers with HTTPS 
  },
  body: JSON.stringify({ "message": "Hello World!" })
};

callback(null, response);
};

C# is a little different in this respect with JavaScript. Because of the strict checks, you define the size of the array and you are supposed to know everything about the array such as its bounds, where the last item was put and what items are unused. You are supposed to copy all the elements of the array into a new, bigger one, if you want to resize it.

So, if you use a raw array, there's no other way other than to maintain the last empty, available index assign items to the array at this index, like you're already doing.

However, if you'd like to have the runtime maintain this information and completely abstract away the array, but still use an array underneath, then C# provides a class named ArrayList that provides this abstraction.

The ArrayList abstracts a loosely typed array of Objects. See the source here.

It takes care of all the issues like resizing the array, maintaining the last index that is available, etc. However, it abstracts / encapsulates this information from you. All you use is the ArrayList.

To push an item of any type into the underlying array at the end of the underlying array, call the Add method on the ArrayList like so:

/* you may or may not define a size using a constructor overload */
var arrayList = new ArrayList(); 

arrayList.Add("Foo");

EDIT: A note about type restriction

Like every programming language and runtime does, C# categorizes heap objects from those that will not go on the heap and will only stay on the function's argument stack. C# notes this distinction by the name Value types vs. Reference types. All things whose value goes on the stack are called Value types, and those that will go on the heap are called Reference types. This is loosely similar to JavaScript's distinction between objects and literals.

You can put anything into an ArrayList in C#, whether the thing is a value type or a reference type. This makes it closest to the JavaScript array in terms of typelessness, although neither of the three -- the JavaScript array, the JavaScript language and the C# ArrayList -- are actually type-less.

So, you could put a number literal, a string literal, an object of a class you made up, a boolean, a float, a double, a struct, just about anything you wanted into an ArrayList.

That is because the ArrayList internally maintains and stores all that you put into it, into an array of Objects, as you will have noted in my original answer and the linked source code.

And when you put something that isn't an object, C# creates a new object of type Object, stores the value of the thing you put into the ArrayList into this new Object type object. This process is called boxing and isn't very much unlike the JavaScript boxing mechanism.

For e.g. in JavaScript, while you could use a numeric literal to invoke a function on the Number object, you couldn't add something to the number literal's prototype.

// Valid javascript
var s = 4.toString();

// Invalid JavaScript code
4.prototype.square = () => 4 * 4;
var square = 4.square();

Just like JavaScript boxes the numeric literal 4 in the call to the toString method, C# boxes all things that are not objects into an Object type when putting them into an ArrayList.

var arrayList = new ArrayList();

arrayList.Add(4); // The value 4 is boxed into a `new Object()` first and then that new object is inserted as the last element in the `ArrayList`.

This involves a certain penalty, as it does in the case of JavaScript as well.

In C#, you can avoid this penalty as C# provides a strongly typed version of the ArrayList, known as the List<T>. So it follows that you cannot put anything into a List<T>; just T types.

However, I assume from your question's text that you already knew that C# had generic structures for strongly typed items. And your question was to have a JavaScript like data structure exhibiting the semantics of typelessness and elasticity, like the JavaScript Array object. In this case, the ArrayList comes closest.

It is also clear from your question that your interest was academic and not to use the structure in a production application.

So, I assume that for a production application, you would already know that a generic / strongly typed data structure (List<T> for example) is better performing than its non-typed one (ArrayList for example).

Currency pipe uses the number one internally for number formatting. So you can use it like this:

{{ number | number : '1.2-2'}}

Check out the PHP cURL functions. They should do what you want.

Or if you just want a simple URL GET then:

$lines = file('http://www.example.com/');

Adding executable permissions, recursively, to all files (not folders) within the current folder with sh extension:

find . -name '*.sh' -type f | xargs chmod +x

* Notice the pipe (|)

Here is how to use UIVibrancyEffect and UIBlurEffect with UIVisualEffectView

Objective-C:

// Blur effect
UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView *blurEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
[blurEffectView setFrame:self.view.bounds];
[self.view addSubview:blurEffectView];

// Vibrancy effect
UIVibrancyEffect *vibrancyEffect = [UIVibrancyEffect effectForBlurEffect:blurEffect];
UIVisualEffectView *vibrancyEffectView = [[UIVisualEffectView alloc] initWithEffect:vibrancyEffect];
[vibrancyEffectView setFrame:self.view.bounds];

// Label for vibrant text
UILabel *vibrantLabel = [[UILabel alloc] init];
[vibrantLabel setText:@"Vibrant"];
[vibrantLabel setFont:[UIFont systemFontOfSize:72.0f]];
[vibrantLabel sizeToFit];
[vibrantLabel setCenter: self.view.center];

// Add label to the vibrancy view
[[vibrancyEffectView contentView] addSubview:vibrantLabel];

// Add the vibrancy view to the blur view
[[blurEffectView contentView] addSubview:vibrancyEffectView];

Swift 4:

    // Blur Effect
    let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.dark)
    let blurEffectView = UIVisualEffectView(effect: blurEffect)
    blurEffectView.frame = view.bounds
    view.addSubview(blurEffectView)

    // Vibrancy Effect
    let vibrancyEffect = UIVibrancyEffect(blurEffect: blurEffect)
    let vibrancyEffectView = UIVisualEffectView(effect: vibrancyEffect)
    vibrancyEffectView.frame = view.bounds

    // Label for vibrant text
    let vibrantLabel = UILabel()
    vibrantLabel.text = "Vibrant"
    vibrantLabel.font = UIFont.systemFont(ofSize: 72.0)
    vibrantLabel.sizeToFit()
    vibrantLabel.center = view.center

    // Add label to the vibrancy view
    vibrancyEffectView.contentView.addSubview(vibrantLabel)

    // Add the vibrancy view to the blur view
    blurEffectView.contentView.addSubview(vibrancyEffectView)

You could use g++ --version in combination with the GCC ABI docs to find out.

When using the $array.Add()-method, you're trying to add the element into the existing array. An array is a collection of fixed size, so you will receive an error because it can't be extended.

$array += $element creates a new array with the same elements as old one + the new item, and this new larger array replaces the old one in the $array-variable

You can use the += operator to add an element to an array. When you use it, Windows PowerShell actually creates a new array with the values of the original array and the added value. For example, to add an element with a value of 200 to the array in the $a variable, type:

    $a += 200

Source: about_Arrays

+= is an expensive operation, so when you need to add many items you should try to add them in as few operations as possible, ex:

$arr = 1..3    #Array
$arr += (4..5) #Combine with another array in a single write-operation

$arr.Count
5

If that's not possible, consider using a more efficient collection like List or ArrayList (see the other answer).

Angular 2 or 4:

There's no more ng-repeat, it's *ngFor now in recent Angular versions!

<table style="padding: 20px; width: 60%;">
    <tr>
      <th  align="left">id</th>
      <th  align="left">status</th>
      <th  align="left">name</th>
    </tr>
    <tr *ngFor="let item of myJSONArray">
      <td>{{item.id}}</td>
      <td>{{item.status}}</td>
      <td>{{item.name}}</td>
    </tr>
</table>

Used this simple JSON:

[{"id":1,"status":"active","name":"A"},
{"id":2,"status":"live","name":"B"},
{"id":3,"status":"active","name":"C"},
{"id":6,"status":"deleted","name":"D"},
{"id":4,"status":"live","name":"E"},
{"id":5,"status":"active","name":"F"}]

Finally, I added the headers this way:

@Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request request = chain.request();
        Request newRequest;

        newRequest = request.newBuilder()
                .addHeader(HeadersContract.HEADER_AUTHONRIZATION, O_AUTH_AUTHENTICATION)
                .addHeader(HeadersContract.HEADER_X_CLIENT_ID, CLIENT_ID)
                .build();
        return chain.proceed(newRequest);
    }

In fact, this is a "how to" subject. So, here is the reference implementation:

    public class BOX
    {
        double height, length, breadth;

1. look for the value of secure_file_priv using the command posted by @vhu: SHOW VARIABLES LIKE "secure_file_priv".
2. define the full path for your query such as: select * from table into outfile 'secure_file_priv_PATH/OUTPUT-FILE' ... rest of your query

See C# Operators for C# operators including OR which is ||

cmd.exe is located in different locations in different versions of Windows. To avoid needing the location of cmd.exe, you can use the command moogs wrote without calling "cmd.exe /C".

Here's an example that worked for me:

1. Open Command Prompt
2. Change directory to where your application's .exe file is located.
3. Execute the following command: runas /user:domain\username Application.exe

So the final step will look something like this in Command Prompt:

C:\Projects\MyProject\bin\Debug>runas /user:domain\username Application.exe

Note: the domain name was required in my situation.

private void readFile() throws Exception {
      AsynchronousFileChannel input=AsynchronousFileChannel.open(Paths.get("E:/dicom_server_storage/abc.txt"),StandardOpenOption.READ);

      input.read(buffer,0,null,new CompletionHandler<Integer,Void>(){
        @Override public void completed(    Integer result,    Void attachment){
          System.out.println("Done reading the file.");
        }
        @Override public void failed(    Throwable exc,    Void attachment){
          System.err.println("An error occured:" + exc.getMessage());

      }
    );
      System.out.println("This thread keeps on running");
      Thread.sleep(100);
    }

In case you expect more than one maximum this will work:

_.maxBy(Object.entries(_.groupBy(x, y => y.length)), y => parseInt(y[0]))[1]

It uses lodash and returns an array.

I had the same error but I discovered that when you import an AddEventModule, you can't import an AddEvent module as it would present an error in this case.

If you find yourself doing things like this regularly it may be worth investigating the object-oriented interface to matplotlib. In your case:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(5)
y = np.exp(x)
fig1, ax1 = plt.subplots()
ax1.plot(x, y)
ax1.set_title("Axis 1 title")
ax1.set_xlabel("X-label for axis 1")

z = np.sin(x)
fig2, (ax2, ax3) = plt.subplots(nrows=2, ncols=1) # two axes on figure
ax2.plot(x, z)
ax3.plot(x, -z)

w = np.cos(x)
ax1.plot(x, w) # can continue plotting on the first axis

It is a little more verbose but it's much clearer and easier to keep track of, especially with several figures each with multiple subplots.

I've gone back and tested and re-tested this, it appears that the only way I can get it to work (since I have some files in the img folder and some in js/css, etc...) is not to use a relative path to my image in the html and have everything referenced to the bundle folder. What a shame :(.

<img src="myimage.png" />

As at MVC 5, if you wish to add any attributes you can simply do

 @Html.EditorFor(m => m.Name, new { htmlAttributes = new { @required = "true", @anotherAttribute = "whatever" } })

Here's a partial solution using xml2. Breaking the solution up into smaller pieces generally makes it easier to ensure everything is lined up:

library(xml2)
data <- read_xml("http://forecast.weather.gov/MapClick.php?lat=29.803&lon=-82.411&FcstType=digitalDWML")

# Point locations
point <- data %>% xml_find_all("//point")
point %>% xml_attr("latitude") %>% as.numeric()
point %>% xml_attr("longitude") %>% as.numeric()

# Start time
data %>% 
  xml_find_all("//start-valid-time") %>% 
  xml_text()

# Temperature
data %>% 
  xml_find_all("//temperature[@type='hourly']/value") %>% 
  xml_text() %>% 
  as.integer()

NOTE: Not 100% Cross Browser

Check browser compatibility @ http://caniuse.com/#search=FileReader

as you will see people have had issues with the not so common browsers, But this could come down to the version of the browser.. I always recommend using something like caniuse to see what generation of browser is supported... This is only a working answer for the user, not a final copy and paste code for people to just use..

The Fiddle: http://jsfiddle.net/d2atnbrt/3/

THE HTML CODE:

<input type="file" id="my_file_input" />
<div id='my_file_output'></div>

THE JS CODE:

var oFileIn;

$(function() {
    oFileIn = document.getElementById('my_file_input');
    if(oFileIn.addEventListener) {
        oFileIn.addEventListener('change', filePicked, false);
    }
});


function filePicked(oEvent) {
    // Get The File From The Input
    var oFile = oEvent.target.files[0];
    var sFilename = oFile.name;
    // Create A File Reader HTML5
    var reader = new FileReader();

    // Ready The Event For When A File Gets Selected
    reader.onload = function(e) {
        var data = e.target.result;
        var cfb = XLS.CFB.read(data, {type: 'binary'});
        var wb = XLS.parse_xlscfb(cfb);
        // Loop Over Each Sheet
        wb.SheetNames.forEach(function(sheetName) {
            // Obtain The Current Row As CSV
            var sCSV = XLS.utils.make_csv(wb.Sheets[sheetName]);   
            var oJS = XLS.utils.sheet_to_row_object_array(wb.Sheets[sheetName]);   

            $("#my_file_output").html(sCSV);
            console.log(oJS)
        });
    };

    // Tell JS To Start Reading The File.. You could delay this if desired
    reader.readAsBinaryString(oFile);
}

This also requires https://cdnjs.cloudflare.com/ajax/libs/xls/0.7.4-a/xls.js to convert to a readable format, i've also used jquery only for changing the div contents and for the dom ready event.. so jquery is not needed

This is as basic as i could get it,

Test XLS File: http://www.whitehouse.gov/sites/default/files/omb/budget/fy2014/assets/receipts.xls

This does not cover XLSX files thought, it should be fairly easy to adjust for them using their examples.

Check this useful method:

URLUtil.guessUrl(urlString)

It makes google.com -> http://google.com

The context lets you provide arguments at call-time, allowing easy customization of generic pre-built helper functions.

some examples:

// stock footage:
function addTo(x){ "use strict"; return x + this; }
function pluck(x){ "use strict"; return x[this]; }
function lt(x){ "use strict"; return x < this; }

// production:
var r = [1,2,3,4,5,6,7,8,9];
var words = "a man a plan a canal panama".split(" ");

// filtering numbers:
_.filter(r, lt, 5); // elements less than 5
_.filter(r, lt, 3); // elements less than 3

// add 100 to the elements:
_.map(r, addTo, 100);

// encode eggy peggy:
_.map(words, addTo, "egg").join(" ");

// get length of words:
_.map(words, pluck, "length"); 

// find words starting with "e" or sooner:
_.filter(words, lt, "e"); 

// find all words with 3 or more chars:
_.filter(words, pluck, 2); 

Even from the limited examples, you can see how powerful an "extra argument" can be for creating re-usable code. Instead of making a different callback function for each situation, you can usually adapt a low-level helper. The goal is to have your custom logic bundling a verb and two nouns, with minimal boilerplate.

Admittedly, arrow functions have eliminated a lot of the "code golf" advantages of generic pure functions, but the semantic and consistency advantages remain.

I always add "use strict" to helpers to provide native [].map() compatibility when passing primitives. Otherwise, they are coerced into objects, which usually still works, but it's faster and safer to be type-specific.

the absolutely minimal (and correct, unlike many of the answers above) version is:

function Monkey(param){
  this.someProperty = param;
}
Monkey.prototype = Object.create(Monster.prototype);
Monkey.prototype.eatBanana = function(banana){ banana.eat() }

That's all. You can read here the longer explanation

If you aren't comfortable with using negative margins, check this out.

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

<div>
  Your Text
</div>

Especially useful when you don't know the width of the div.

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

Python is almost a functional language. It's "functional lite".

It has extra features, so it isn't pure enough for some.

It also lacks some features, so it isn't complete enough for some.

The missing features are relatively easy to write. Check out posts like this on FP in Python.

varvy.com (100/100 Google page speed insight) loads google analitycs code only if user make a scroll of the page:

var fired = false;

window.addEventListener("scroll", function(){
    if ((document.documentElement.scrollTop != 0 && fired === false) || (document.body.scrollTop != 0 && fired === false)) {

        (function(i,s,o,g,r,a,m{i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

        ga('create', 'UA-XXXXXXXX-X', 'auto');
        ga('send', 'pageview');

        fired = true;
    }
}, true);

Here's a mathematical answer (also works for negative numbers):

function numDigits(x) {
  return Math.max(Math.floor(Math.log10(Math.abs(x))), 0) + 1;
}

And an optimized version of the above (more efficient bitwise operations):

function numDigits(x) {
  return (Math.log10((x ^ (x >> 31)) - (x >> 31)) | 0) + 1;
}

Essentially, we start by getting the absolute value of the input to allow negatives values to work correctly. Then we run the through the log10 operation to give us what power of 10 the input is (if you were working in another base, you would use the logarithm for that base), which is the number of digits. Then we floor the output to only grab the integer part of that. Finally, we use the max function to fix decimal values (any fractional value between 0 and 1 just returns 1, instead of a negative number), and add 1 to the final output to get the count.

The above assumes (based on your example input) that you wish to count the number of digits in integers (so 12345 = 5, and thus 12345.678 = 5 as well). If you would like to count the total number of digits in the value (so 12345.678 = 8), then add this before the 'return' in either function above:

x = Number(String(x).replace(/[^0-9]/g, ''));

Following on what @magnoz was saying, here is a code implementation of his answer.

constructor() {
    let windowLen = window.frames.length;
    let parentLen = parent.frames.length;

    if (windowLen == 0 && parentLen >= 1) {
        this.isInIframe = true
        console.log('Is in Iframe!')
    } else {
        console.log('Is in main window!')
    }
}

You don't need JavaScript for this. You can change the cursor to anything you want using CSS :

selector {
    cursor: url(myimage.jpg), auto;
}

There can be so many issues but if you are using oracle 10g , uninstall oracle 10g and also remove the value from registry and install oracle 11g. But if you are using oracle 11g , first go and check on registry if it is pointing to right home. Sometimes there can be more than one home because you install sql developer again and again . In that case either you can remove unnecessary home registry value or you can add tns and sql.net file to all of those home, that might resolve the issue. I resolved mine in that way.

Try

echo -e "hello\nworld"
hello
world

How I work to automate Office / Excel:

1. Record a macro, this will generate a VBA template
2. Edit the VBA template so it will match my needs
3. Convert to VB.Net (A small step for men)
4. Leave it in VB.Net, Much more easy as doing it using C#

i had this problem and i solved it using javascript

>>> k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]
>>> import itertools
>>> k.sort()
>>> list(k for k,_ in itertools.groupby(k))
[[1, 2], [3], [4], [5, 6, 2]]

itertools often offers the fastest and most powerful solutions to this kind of problems, and is well worth getting intimately familiar with!-)

Edit: as I mention in a comment, normal optimization efforts are focused on large inputs (the big-O approach) because it's so much easier that it offers good returns on efforts. But sometimes (essentially for "tragically crucial bottlenecks" in deep inner loops of code that's pushing the boundaries of performance limits) one may need to go into much more detail, providing probability distributions, deciding which performance measures to optimize (maybe the upper bound or the 90th centile is more important than an average or median, depending on one's apps), performing possibly-heuristic checks at the start to pick different algorithms depending on input data characteristics, and so forth.

Careful measurements of "point" performance (code A vs code B for a specific input) are a part of this extremely costly process, and standard library module timeit helps here. However, it's easier to use it at a shell prompt. For example, here's a short module to showcase the general approach for this problem, save it as nodup.py:

import itertools

k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]

def doset(k, map=map, list=list, set=set, tuple=tuple):
  return map(list, set(map(tuple, k)))

def dosort(k, sorted=sorted, xrange=xrange, len=len):
  ks = sorted(k)
  return [ks[i] for i in xrange(len(ks)) if i == 0 or ks[i] != ks[i-1]]

def dogroupby(k, sorted=sorted, groupby=itertools.groupby, list=list):
  ks = sorted(k)
  return [i for i, _ in itertools.groupby(ks)]

def donewk(k):
  newk = []
  for i in k:
    if i not in newk:
      newk.append(i)
  return newk

# sanity check that all functions compute the same result and don't alter k
if __name__ == '__main__':
  savek = list(k)
  for f in doset, dosort, dogroupby, donewk:
    resk = f(k)
    assert k == savek
    print '%10s %s' % (f.__name__, sorted(resk))

Note the sanity check (performed when you just do python nodup.py) and the basic hoisting technique (make constant global names local to each function for speed) to put things on equal footing.

Now we can run checks on the tiny example list:

$ python -mtimeit -s'import nodup' 'nodup.doset(nodup.k)'
100000 loops, best of 3: 11.7 usec per loop
$ python -mtimeit -s'import nodup' 'nodup.dosort(nodup.k)'
100000 loops, best of 3: 9.68 usec per loop
$ python -mtimeit -s'import nodup' 'nodup.dogroupby(nodup.k)'
100000 loops, best of 3: 8.74 usec per loop
$ python -mtimeit -s'import nodup' 'nodup.donewk(nodup.k)'
100000 loops, best of 3: 4.44 usec per loop

confirming that the quadratic approach has small-enough constants to make it attractive for tiny lists with few duplicated values. With a short list without duplicates:

$ python -mtimeit -s'import nodup' 'nodup.donewk([[i] for i in range(12)])'
10000 loops, best of 3: 25.4 usec per loop
$ python -mtimeit -s'import nodup' 'nodup.dogroupby([[i] for i in range(12)])'
10000 loops, best of 3: 23.7 usec per loop
$ python -mtimeit -s'import nodup' 'nodup.doset([[i] for i in range(12)])'
10000 loops, best of 3: 31.3 usec per loop
$ python -mtimeit -s'import nodup' 'nodup.dosort([[i] for i in range(12)])'
10000 loops, best of 3: 25 usec per loop

the quadratic approach isn't bad, but the sort and groupby ones are better. Etc, etc.

If (as the obsession with performance suggests) this operation is at a core inner loop of your pushing-the-boundaries application, it's worth trying the same set of tests on other representative input samples, possibly detecting some simple measure that could heuristically let you pick one or the other approach (but the measure must be fast, of course).

It's also well worth considering keeping a different representation for k -- why does it have to be a list of lists rather than a set of tuples in the first place? If the duplicate removal task is frequent, and profiling shows it to be the program's performance bottleneck, keeping a set of tuples all the time and getting a list of lists from it only if and where needed, might be faster overall, for example.

I tried all the ways listed on the web for a whole day, but I didn't get any solutions. Then, I followed a link and in just two minutes my problem was solved!

By the way, it's for Windows users!

Find out the vendor id of the device from device manager.
To do this, connect the OTG port to the USB port of your computer.
Go to Start Menu and right-click on “My Computer” and chose “Properties”.
Select the “Devices” option which will open “Device Manager”.
Select your device (mostly in USB devices or Other devices) and right-click and choose “Properties”.
Choose the “Details” tab and select “Hardware Ids” from the property dropdown, you can see the hardware id, in my case it was x2207 .
Open android_winusb.inf and add these lines:

;<Device name>   in our case I gave MK808
%SingleAdbInterface%        = USB_INSTALL, USB\VID_2207&PID_0010&MI_01
%CompositeAdbInterface%     = USB_INSTALL, USB\VID_2207&PID_0010&REV_0222&MI_01

Open C:\Users\.android\adb_usb.ini and add the following entry

0x<device id>  .. in our case it is 0x2207

Restart ADB by

adb kill-server
adb start-server

Now ADB should recognize the device.

findstr sometimes hangs unexpectedly when searching large files.

I haven't confirmed the exact conditions or boundary sizes. I suspect any file larger 2GB may be at risk.

I have had mixed experiences with this, so it is more than just file size. This looks like it may be a variation on FINDSTR hangs on XP and Windows 7 if redirected input does not end with LF, but as demonstrated this particular problem manifests when input is not redirected.

The following command line session (Windows 7) demonstrates how findstr can hang when searching a 3GB file.

C:\Data\Temp\2014-04>rem On the 3GB file, findstr hangs and must be aborted... even though it clearly reaches end of file

Note, I've verified in a hex editor that all lines are terminated with CRLF. The only anomaly is that the file is terminated with 0x1A due to the way copy works. Note however, that this anomaly doesn't cause a problem on "small" files.

With additional testing I have confirmed the following:

• Using copy with the /b option for binary files prevents the addition of the 0x1A character, and findstr doesn't hang on the 3GB file.
• Terminating the 3GB file with a different character also causes a findstr to hang.
• The 0x1A character doesn't cause any problems on a "small" file. (Similarly for other terminating characters.)
• Adding CRLF after 0x1A resolves the problem. (LF by itself would probably suffice.)
• Using type to pipe the file into findstr works without hanging. (This might be due to a side effect of either type or | that inserts an additional End Of Line.)
• Use redirected input < also causes findstr to hang. But this is expected; as explained in dbenham's post: "redirected input must end in LF".

Moving an application from one database to another isn't very common, but sooner or later you may find yourself working on another project using a different RDBMS. If you're at home with PDO then there will at least be one thing less to learn at that point.

Apart from that I find the PDO API a little more intuitive, and it feels more truly object oriented. mysqli feels like it is just a procedural API that has been objectified, if you know what I mean. In short, I find PDO easier to work with, but that is of course subjective.

The var_dump equivalent in JavaScript? Simply, there isn't one.

But, that doesn't mean you're left helpless. Like some have suggested, use Firebug (or equivalent in other browsers), but unlike what others suggested, don't use console.log when you have a (slightly) better tool console.dir:

console.dir(object)

Prints an interactive listing of all properties of the object. This looks identical to the view that you would see in the DOM tab.

fname = input("Enter file name: ")
num_lines = 0

with open(fname, 'r') as f: #lines count
    for line in f:
        num_lines += 1

num_lines_input = int (input("Enter line numbers: "))

if num_lines_input <= num_lines:
    f = open(fname, "r")
    for x in range(num_lines_input):
        a = f.readline()
        print(a)

else:
    f = open(fname, "r")
    for x in range(num_lines_input):
        a = f.readline()
        print(a)
        print("Don't have", num_lines_input, " lines print as much as you can")


print("Total lines in the text",num_lines)

I've been struggling with the issue for a while, so just in case when someone makes the same stupid mistake as me... Inside the <td> I had the element with white-space:pre style applied. That made all my table/tr/td tricks discarded. When I removed that style, suddenly all my text was nicely formatted inside the td.

So, always check the main container (like table or td) but also, always check if you don't cancel your beautifull code somewhere deeper :)

If you are building a windows app try to build as x64 instead of Any CPU. It should work fine.

The logic of determining a "wrong" url is specific to your application. It could be a simple file not found error or something else if you are doing a RESTful app. Once you've figured that out, sending a redirect is as simple as:

response.writeHead(302, {
  'Location': 'your/404/path.html'
  //add other headers here...
});
response.end();

ALTER TABLE
    `table_name`
MODIFY COLUMN
    `column_name2` enum(
        'existing_value1',
        'existing_value2',
        'new_value1',
        'new_value2'
    )
NOT NULL AFTER `column_name1`;

I think Asa's answer is essentially correct, but you could extend it a little to act more like mkdir -p, either:

import os

def mkdir_path(path):
    if not os.access(path, os.F_OK):
        os.mkdirs(path)

or

import os
import errno

def mkdir_path(path):
    try:
        os.mkdirs(path)
    except os.error, e:
        if e.errno != errno.EEXIST:
            raise

These both handle the case where the path already exists silently but let other errors bubble up.

I had the same issue and i solved it by resetting the adb on eclipse.

on eclipse Go to:

DDMS(top right corner) -> Devices -> reset adb

I tried a few things in this scenario.

I removed ios and installed many times. Went down the path of deleting Splash screens to no avail! Bitcode on/off so many times.

However, after selecting a iOS provisioning team, and running pod update inside ./platforms/ios, I am pleased to announce this resolved my problems.

Hopefully you can try the same and get some resolution?

I recently restored my bookmarks and was looking for a way to restore the FavIcons without visiting each page. My search brought me to this thread.

For those in a similar circumstance merely download the FAVICON RELOADER addon. Once installed you will find the "reload favorite icons" command in your BOOKMARKS dropdown menu.

https://addons.mozilla.org/en-US/firefox/addon/faviconreloader/?src=api

The signature:

bool operator<<(const obj&, const obj&);

Seems rather suspect, this does not fit the stream convention nor the bitwise convention so it looks like a case of operator overloading abuse, operator < should return bool but operator << should probably return something else.

If you meant so say:

ostream& operator<<(ostream&, const obj&); 

Then since you can't add functions to ostream by necessity the function must be a free function, whether it a friend or not depends on what it has to access (if it doesn't need to access private or protected members there's no need to make it friend).

The method show() must be called from the User-Interface (UI) thread, while doInBackground() runs on different thread which is the main reason why AsyncTask was designed.

You have to call show() either in onProgressUpdate() or in onPostExecute().

For example:

class ExampleTask extends AsyncTask<String, String, String> {

    // Your onPreExecute method.

    @Override
    protected String doInBackground(String... params) {
        // Your code.
        if (condition_is_true) {
            this.publishProgress("Show the dialog");
        }
        return "Result";
    }

    @Override
    protected void onProgressUpdate(String... values) {
        super.onProgressUpdate(values);
        connectionProgressDialog.dismiss();
        downloadSpinnerProgressDialog.show();
    }
}

You can try using .net:

$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $computer1)
$RegKey= $Reg.OpenSubKey("SOFTWARE\\Veritas\\NetBackup\\CurrentVersion")
$NetbackupVersion1 = $RegKey.GetValue("PackageVersion")

Make a list from items in an iterable

It seems best to first generalize all the possible forms rather than giving specific answers to questions. Otherwise, the reader won't know how the answer was determined. Here are a few generalized forms I thought up before I got a headache trying to decide if a final else' clause could be used in the last form.

[expression1(item)                                        for item in iterable]

[expression1(item) if conditional1                        for item in iterable]

[expression1(item) if conditional1 else expression2(item) for item in iterable]

[expression1(item) if conditional1 else expression2(item) for item in iterable if conditional2]

The value of item doesn't need to be used in any of the conditional clauses. A conditional3 can be used as a switch to either add or not add a value to the output list.

For example, to create a new list that eliminates empty strings or whitespace strings from the original list of strings:

newlist = [s for s in firstlist if s.strip()]

If you want to alter order for columns in Sql server, There is no direct way to do this in SQL Server currently.

Have a look at http://blog.sqlauthority.com/2008/04/08/sql-server-change-order-of-column-in-database-tables/

You can change order while edit design for table.

If you want disable it in Global, you can write a custom middleware, like this

from django.utils.deprecation import MiddlewareMixin

class DisableCsrfCheck(MiddlewareMixin):

    def process_request(self, req):
        attr = '_dont_enforce_csrf_checks'
        if not getattr(req, attr, False):
            setattr(req, attr, True)

then add this class youappname.middlewarefilename.DisableCsrfCheck to MIDDLEWARE_CLASSES lists, before django.middleware.csrf.CsrfViewMiddleware

use np.random.randint() as np.random.random_integers() is deprecated

random_matrix = np.random.randint(min_val,max_val,(<num_rows>,<num_cols>))

As @weichsel stated, CGFloat is just a typedef for either float or double. You can see for yourself by Command-double-clicking on "CGFloat" in Xcode — it will jump to the CGBase.h header where the typedef is defined. The same approach is used for NSInteger and NSUInteger as well.

These types were introduced to make it easier to write code that works on both 32-bit and 64-bit without modification. However, if all you need is float precision within your own code, you can still use float if you like — it will reduce your memory footprint somewhat. Same goes for integer values.

I suggest you invest the modest time required to make your app 64-bit clean and try running it as such, since most Macs now have 64-bit CPUs and Snow Leopard is fully 64-bit, including the kernel and user applications. Apple's 64-bit Transition Guide for Cocoa is a useful resource.

One can replace unicode with u''.__class__ to handle the missing unicode class in Python 3. For both Python 2 and 3, you can use the construct

isinstance(unicode_or_str, u''.__class__)

or

type(unicode_or_str) == type(u'')

Depending on your further processing, consider the different outcome:

Python 3

>>> isinstance('text', u''.__class__)
True
>>> isinstance(u'text', u''.__class__)
True

Python 2

>>> isinstance(u'text', u''.__class__)
True
>>> isinstance('text', u''.__class__)
False

See Function Definitions in the Language Reference.

If the form *identifier is present, it is initialized to a tuple receiving any excess positional parameters, defaulting to the empty tuple. If the form **identifier is present, it is initialized to a new dictionary receiving any excess keyword arguments, defaulting to a new empty dictionary.

Also, see Function Calls.

Assuming that one knows what positional and keyword arguments are, here are some examples:

Example 1:

# Excess keyword argument (python 2) example:
def foo(a, b, c, **args):
    print "a = %s" % (a,)
    print "b = %s" % (b,)
    print "c = %s" % (c,)
    print args

foo(a="testa", d="excess", c="testc", b="testb", k="another_excess")

As you can see in the above example, we only have parameters a, b, c in the signature of the foo function. Since d and k are not present, they are put into the args dictionary. The output of the program is:

a = testa
b = testb
c = testc
{'k': 'another_excess', 'd': 'excess'}

Example 2:

# Excess positional argument (python 2) example:
def foo(a, b, c, *args):
    print "a = %s" % (a,)
    print "b = %s" % (b,)
    print "c = %s" % (c,)
    print args

foo("testa", "testb", "testc", "excess", "another_excess")

Here, since we're testing positional arguments, the excess ones have to be on the end, and *args packs them into a tuple, so the output of this program is:

a = testa
b = testb
c = testc
('excess', 'another_excess')

You can also unpack a dictionary or a tuple into arguments of a function:

def foo(a,b,c,**args):
    print "a=%s" % (a,)
    print "b=%s" % (b,)
    print "c=%s" % (c,)
    print "args=%s" % (args,)

argdict = dict(a="testa", b="testb", c="testc", excessarg="string")
foo(**argdict)

Prints:

a=testa
b=testb
c=testc
args={'excessarg': 'string'}

And

def foo(a,b,c,*args):
    print "a=%s" % (a,)
    print "b=%s" % (b,)
    print "c=%s" % (c,)
    print "args=%s" % (args,)

argtuple = ("testa","testb","testc","excess")
foo(*argtuple)

Prints:

a=testa
b=testb
c=testc
args=('excess',)

You should try with the parent elements;

html, body, form, main {
    height: 100%;
}

Then this will be enough :

#s7 {
   height: 100%;
}

Insted of using System.Net.WebClient I would recommend to have a look on System.Net.Http.HttpClient which was introduced with net 4.5 and makes your life much easier.

Also microsoft recommends to use the HttpClient on this article

http://msdn.microsoft.com/en-us/library/system.net.webclient(VS.90).aspx

An example could look like this:

var client = new HttpClient();
var content = new MultipartFormDataContent
{
     { new StringContent("myUserId"), "userid"},
     { new StringContent("myFileName"), "filename"},
     { new StringContent("myPassword"), "password"},
     { new StringContent("myType"), "type"}
};

var responseMessage = await client.PostAsync("some url", content);        
var stream = await responseMessage.Content.ReadAsStreamAsync();

I suppose one thing that may be concerning you is whether or not the entries could change, so that the 2 becomes a different number, for instance. You can put your mind at ease here, because in Python, integers are immutable, meaning they cannot change after they are created.

Not everything in Python is immutable, though. For example, lists are mutable---they can change after being created. So for example, if you had a list of lists

>>> a = [[1], [2], [3]]
>>> a[0].append(7)
>>> a
[[1, 7], [2], [3]]

Here, I changed the first entry of a (I added 7 to it). One could imagine shuffling things around, and getting unexpected things here if you are not careful (and indeed, this does happen to everyone when they start programming in Python in some way or another; just search this site for "modifying a list while looping through it" to see dozens of examples).

It's also worth pointing out that x = x + [a] and x.append(a) are not the same thing. The second one mutates x, and the first one creates a new list and assigns it to x. To see the difference, try setting y = x before adding anything to x and trying each one, and look at the difference the two make to y.

Better way, with solution to tab and chrome problem and new jquery way

$("#element").on("focus keyup", function(e){

        var keycode = e.keyCode ? e.keyCode : e.which ? e.which : e.charCode;
        if(keycode === 9 || !keycode){
            // Hacemos select
            var $this = $(this);
            $this.select();

            // Para Chrome's que da problema
            $this.on("mouseup", function() {
                // Unbindeamos el mouseup
                $this.off("mouseup");
                return false;
            });
        }
    });

This is what worked for me:

.pdf::before {
    content: url('path/to/image.png');
    display: flex;
    align-items: center;
    justify-content: center;
    height: inherit;
}

Method method = someVariable.class.getMethod(SomeClass);
String status = (String) method.invoke(method);

SomeClass is the class and someVariable is a variable.

You should also be able to do:

apt install sudo

sudo -i -u tomcat

Then you should be the tomcat user. It's not clear which Linux distribution you're using, but this works with Ubuntu 18.04 LTS, for example.

Adding up to other answers you need to export the class to use in a different class. This is a typescript version of it.

//Constants.tsx
const DEBUG: boolean = true;

export class Constants {
  static get DEBUG(): boolean {
    return DEBUG;
  }
}

//Anotherclass.tsx
import { Constants } from "Constants";

if (Constants.DEBUG) {
  console.log("debug mode")
}

This happened to me today. I was able to track down the cause: The project included a header file which no longer existed on disk.

Removing the file from the project solved the problem.

You are looking for

MyList.Select(x=>x.Name).ToArray();

Since Select is an Extension method make sure to add that namespace by adding a

using System.Linq

to your file - then it will show up with Intellisense.

I have been thinking about this issue recently. There really doesn't seem to be any restriction on use of META-INF. There are certain strictures, of course, about the necessity of putting the manifest there, but there don't appear to be any prohibitions about putting other stuff there.

Why is this the case?

The cxf case may be legit. Here's another place where this non-standard is recommended to get around a nasty bug in JBoss-ws that prevents server-side validation against the schema of a wsdl.

http://community.jboss.org/message/570377#570377

But there really don't seem to be any standards, any thou-shalt-nots. Usually these things are very rigorously defined, but for some reason, it seems there are no standards here. Odd. It seems like META-INF has become a catchall place for any needed configuration that can't easily be handled some other way.

Scipy.org recommends that you use arrays:

*'array' or 'matrix'? Which should I use? - Short answer

Use arrays.

• They are the standard vector/matrix/tensor type of numpy. Many numpy function return arrays, not matrices.

• There is a clear distinction between element-wise operations and linear algebra operations.

• You can have standard vectors or row/column vectors if you like.

The only disadvantage of using the array type is that you will have to use dot instead of * to multiply (reduce) two tensors (scalar product, matrix vector multiplication etc.).

Use Dictionary - it uses hashtable but is typesafe.

Also, your Java code for

int a = map.get(key);
//continue with your logic

will be best coded in C# this way:

int a;
if(dict.TryGetValue(key, out a)){
//continue with your logic
}

This way, you can scope the need of variable "a" inside a block and it is still accessible outside the block if you need it later.

You can extract method:

public int cmp(String txt, String otherTxt)
{
    if ( txt == null )
        return otjerTxt == null ? 0 : 1;

    if ( otherTxt == null )
          return 1;

    return txt.compareToIgnoreCase(otherTxt);
}

public int compareTo(Metadata other) {
   int result = cmp( name, other.name); 
   if ( result != 0 )  return result;
   return cmp( value, other.value); 

}

Some times this problem arise when Application is build in one PC and try to run another PC. And also build the application with Visual Studio 2010.I have the following problem

restart your PC and try again.

This is a simple task. You can follow the following steps.

1. Create a folder in your solution and name it Reports.
2. Add an ASP.Net web form and name it ReportView.aspx

3. Create a Class ReportData and add it to the Reports folder. Add the following code to the Class.

   public class ReportData  
   {  
       public ReportData()  
       {  
           this.ReportParameters = new List<Parameter>();  
           this.DataParameters = new List<Parameter>();  
       }
   
       public bool IsLocal { get; set; }
       public string ReportName { get; set; }
       public List<Parameter> ReportParameters { get; set; }
       public List<Parameter> DataParameters { get; set; }
   }
   
   public class Parameter  
   {  
       public string ParameterName { get; set; }  
       public string Value { get; set; }  
   }
   

4. Add another Class and name it ReportBasePage.cs. Add the following code in this Class.

   public class ReportBasePage : System.Web.UI.Page
   {
       protected ReportData ReportDataObj { get; set; }
   
       protected override void OnInit(EventArgs e)
       {
           base.OnInit(e);
           if (HttpContext.Current != null)
               if (HttpContext.Current.Session["ReportData"] != null)
               {
                   ReportDataObj = HttpContext.Current.Session["ReportData"] as ReportData;
                   return;
               }
           ReportDataObj = new ReportData();
           CaptureRouteData(Page.Request);
       }
   
   
       private void CaptureRouteData(HttpRequest request)
       {
           var mode = (request.QueryString["rptmode"] + "").Trim();
           ReportDataObj.IsLocal = mode == "local" ? true : false;
           ReportDataObj.ReportName = request.QueryString["reportname"] + "";
           string dquerystr = request.QueryString["parameters"] + "";
           if (!String.IsNullOrEmpty(dquerystr.Trim()))
           {
               var param1 = dquerystr.Split(',');
               foreach (string pm in param1)
               {
                   var rp = new Parameter();
                   var kd = pm.Split('=');
                   if (kd[0].Substring(0, 2) == "rp")
                   {
                       rp.ParameterName = kd[0].Replace("rp", "");
                       if (kd.Length > 1) rp.Value = kd[1];
                       ReportDataObj.ReportParameters.Add(rp);
                   }
                   else if (kd[0].Substring(0, 2) == "dp")
                   {
                       rp.ParameterName = kd[0].Replace("dp", "");
                       if (kd.Length > 1) rp.Value = kd[1];
                       ReportDataObj.DataParameters.Add(rp);
                   }
               }
           }
       }
   }
   

5. Add ScriptManager to the ReportView.aspx page. Now add a Report Viewer to the page. In report viewer set the property AsyncRendering="false". The code is given below.

       <rsweb:ReportViewer ID="ReportViewerRSFReports" runat="server" AsyncRendering="false"
           Width="1271px" Height="1000px" >
       </rsweb:ReportViewer>
   

6. Add two NameSpace in ReportView.aspx.cs

   using Microsoft.Reporting.WebForms;
   using System.IO;
   

7. Change the System.Web.UI.Page to ReportBasePage. Just replace your code using the following.

   public partial class ReportView : ReportBasePage
   {
       protected void Page_Load(object sender, EventArgs e)
       {
           if (!IsPostBack)
           {
               RenderReportModels(this.ReportDataObj);
           }
       }
   
       private void RenderReportModels(ReportData reportData)
       {
           // This is the Data Access Layer from which a method is called to fill data to the list.
           RASolarERPData dal = new RASolarERPData();
           List<ClosingInventoryValuation> objClosingInventory = new List<ClosingInventoryValuation>();
   
           // Reset report properties.
           ReportViewerRSFReports.Height = Unit.Parse("100%");
           ReportViewerRSFReports.Width = Unit.Parse("100%");
           ReportViewerRSFReports.CssClass = "table";
   
           // Clear out any previous datasources.
           this.ReportViewerRSFReports.LocalReport.DataSources.Clear();
   
           // Set report mode for local processing.
           ReportViewerRSFReports.ProcessingMode = ProcessingMode.Local;
   
           // Validate report source.
           var rptPath = Server.MapPath(@"./Report/" + reportData.ReportName +".rdlc");
   
           //@"E:\RSFERP_SourceCode\RASolarERP\RASolarERP\Reports\Report\" + reportData.ReportName + ".rdlc";
           //Server.MapPath(@"./Report/ClosingInventory.rdlc");
   
           if (!File.Exists(rptPath))
               return;
   
           // Set report path.
           this.ReportViewerRSFReports.LocalReport.ReportPath = rptPath;
   
           // Set report parameters.
           var rpPms = ReportViewerRSFReports.LocalReport.GetParameters();
           foreach (var rpm in rpPms)
           {
               var p = reportData.ReportParameters.SingleOrDefault(o => o.ParameterName.ToLower() == rpm.Name.ToLower());
               if (p != null)
               {
                   ReportParameter rp = new ReportParameter(rpm.Name, p.Value);
                   ReportViewerRSFReports.LocalReport.SetParameters(rp);
               }
           }
   
           //Set data paramater for report SP execution
           objClosingInventory = dal.ClosingInventoryReport(this.ReportDataObj.DataParameters[0].Value);
   
           // Load the dataSource.
           var dsmems = ReportViewerRSFReports.LocalReport.GetDataSourceNames();
           ReportViewerRSFReports.LocalReport.DataSources.Add(new ReportDataSource(dsmems[0], objClosingInventory));
   
           // Refresh the ReportViewer.
           ReportViewerRSFReports.LocalReport.Refresh();
       }
   }
   

8. Add a Folder to the Reports Folder and name it Report. Now add a RDLC report to the Reports/Report folder and name it ClosingInventory.rdlc.

9. Now add a Controller and name it ReportController. In the controller add the following action method.

   public ActionResult ReportViewer()
       {                
           ViewData["reportUrl"] = "../Reports/View/local/ClosingInventory/";
   
           return View();
       }
   

10. Add a view page click on the ReportViewer Controller. Name the view page ReportViewer.cshtml. Add the following code to the view page.

    @using (Html.BeginForm("Login"))
     { 
           @Html.DropDownList("ddlYearMonthFormat", new SelectList(ViewBag.YearMonthFormat, "YearMonthValue",
     "YearMonthName"), new { @class = "DropDown" })
    
    Stock In Transit: @Html.TextBox("txtStockInTransit", "", new { @class = "LogInTextBox" })
    
    <input type="submit" onclick="return ReportValidationCheck();" name="ShowReport"
                     value="Show Report" />
    
    }
    

11. Add an Iframe. Set the property of the Iframe as follows

    frameborder="0"  width="1000"; height="1000"; style="overflow:hidden;"
    scrolling="no"
    

12. Add Following JavaScript to the viewer.

    function ReportValidationCheck() {
    
        var url = $('#hdUrl').val();
        var yearmonth = $('#ddlYearMonthFormat').val();      
        var stockInTransit = $('#txtStockInTransit').val()
    
        if (stockInTransit == "") {
            stockInTransit = 0;
        }
    
        if (yearmonth == "0") {
            alert("Please Select Month Correctly.");
        }
        else {
    
            //url = url + "dpSpYearMonth=" + yearmonth + ",rpYearMonth=" + yearmonth + ",rpStockInTransit=" + stockInTransit;
    
            url = "../Reports/ReportView.aspx?rptmode=local&reportname=ClosingInventory&parameters=dpSpYearMonth=" + yearmonth + ",rpYearMonth=" + yearmonth + ",rpStockInTransit=" + stockInTransit;
    
            var myframe = document.getElementById("ifrmReportViewer");
            if (myframe !== null) {
                if (myframe.src) {
                    myframe.src = url;
                }
                else if (myframe.contentWindow !== null && myframe.contentWindow.location !== null) {
                    myframe.contentWindow.location = url;
                }
                else { myframe.setAttribute('src', url); }
            }
        }
    
        return false;
    }
    

13. Web.config file add the following key to the appSettings section

    add key="UnobtrusiveJavaScriptEnabled" value="true"
    

14. In system.web handlers Section add the following key

    add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
    

15. Change your data source to your own. This solution is very simple and I think every one will enjoy it.

You're calling both wait and notifyAll without using a synchronized block. In both cases the calling thread must own the lock on the monitor you call the method on.

From the docs for notify (wait and notifyAll have similar documentation but refer to notify for the fullest description):

This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

Only one thread at a time can own an object's monitor.

Only one thread will be able to actually exit wait at a time after notifyAll as they'll all have to acquire the same monitor again - but all will have been notified, so as soon as the first one then exits the synchronized block, the next will acquire the lock etc.

Is this what you are looking for?

Here is perhaps the simplest explanation of how OAuth2 works for all 4 grant types, i.e., 4 different flows where the app can acquire the access token.

Similarity

All grant type flows have 2 parts:

• Get access token
• Use access token

The 2nd part 'use access token' is the same for all flows

Difference

The 1st part of the flow 'get access token' for each grant type varies.

However, in general the 'get access token' part can be summarized as consisting 5 steps:

1. Pre-register your app (client) with OAuth provider, e.g., Twitter, etc. to get client id/secret
2. Create a social login button with client id & required scopes/permissions on your page so when clicked user gets redirected to OAuth provider to be authenticated
3. OAuth provider request user to grant permission to your app (client)
4. OAuth provider issues code
5. App (client) acquires access token

Here is a side-by-side diagram comparing how each grant type flow is different based on the 5 steps.

This diagram is from https://blog.oauth.io/introduction-oauth2-flow-diagrams/

Each have different levels of implementation difficulty, security, and uses cases. Depending on your needs and situation, you will have to use one of them. Which to use?

Client Credential: If your app is only serving a single user

Resource Owner Password Crendential: This should be used only as last resort as the user has to hand over his credentials to the app, which means the app can do everything the user can

Authorization Code: The best way to get user authorization

Implicit: If you app is mobile or single-page app

There is more explanation of the choice here: https://blog.oauth.io/choose-oauth2-flow-grant-types-for-app/

In my case value was not an integer but a String. getNameByCode method can be added to the enum to get name of a String value-

enum CODE {
    SUCCESS("SCS"), DELETE("DEL");

    private String status;

    /**
     * @return the status
     */
    public String getStatus() {
        return status;
    }

    /**
     * @param status
     *            the status to set
     */
    public void setStatus(String status) {
        this.status = status;
    }

    private CODE(String status) {
        this.status = status;
    }

    public static String getNameByCode(String code) {
        for (int i = 0; i < CODE.values().length; i++) {
            if (code.equals(CODE.values()[i].status))
                return CODE.values()[i].name();
        }
        return null;
    }

You can try to use underscore.js

First convert the lines in arrays using the toArray function :

var letters = _.toArray(a,b,c,d);
var numbers = _.toArray(1,2,3,4);

Then object the arrays together using the object function :

var json = _.object(letters, numbers);

By then, the json var should contain something like :

{"a": 1,"b": 2,"c": 3,"d": 4}

You can use PropertyInfo.SetValue(obj, null). If called on a value type it will give you the default. This behavior is documented in .NET 4.0 and in .NET 4.5.

    $(document).ready(function () {
        // using ascii 17 for ctrl, 18 for alt and 83 for "S"
        // ctr+alt+S
        var map = { 17: false, 18: false, 83: false };
        $(document).keyup(function (e) {
            if (e.keyCode in map) {
                map[e.keyCode] = true;
                if (map[17] && map[18] && map[83]) {
                    // Write your own code here, what  you want to do
                    map[17] = false;
                    map[18] = false;
                    map[83] = false;
                }
            }
            else {
                // if u press any other key apart from that "map" will reset.
                map[17] = false;
                map[18] = false;
                map[83] = false;
            }
        });

    });

I was having the same problem with the AND() breaking the conditional formatting. I just happened to try treating the AND as multiplication, and it works! Remove the AND() function and just multiply your arguments. Excel will treat the booleans as 1 for true and 0 for false. I just tested this formula and it seems to work.

=(INDIRECT(ADDRESS(4,COLUMN()))>=INDIRECT(ADDRESS(ROW(),4)))*(INDIRECT(ADDRESS(4,COLUMN()))<=INDIRECT(ADDRESS(ROW(),5)))

Looks like when upgrading to OS X El Capitain, the /usr/local directory is modified in multiple ways :

1. user permissions are reset (this is also a problem for people using Homebrew)
2. binaries and symlinks might have been deleted or altered

[Edit] There's also a preliminary thing to do : upgrade Xcode...

Solution for #1 :

$ sudo chown -R $(whoami):admin /usr/local

This will fix permissions on the /usr/local directory which will then help both gem install and brew install|link|... commands working properly.

Solution to #2 :

Ruby based issues

Make sure you have fixed the permissions of the /usr/local directory (see #1 above)

First try to reinstall your gem using :

sudo gem install <gemname>

Note that it will install the latest version of the specified gem.

If you don't want to face backward-compatibility issues, I suggest that you first determine which version of which gem you want to get and then reinstall it with the -v version. See an exemple below to make sure that the system won't get a new version of capistrano.

$ gem list | grep capistrano
capistrano (3.4.0, 3.2.1, 2.14.2)
$ sudo gem install capistrano -v 3.4.0

Brew based issues

Update brew and upgrade your formulas

$ brew update
$ brew upgrade

You might also need to re-link some of them manually

$ brew link <formula>

Upper camel case ("TestString") to lower camel case ("testString") without using regex (let's face it, regex is evil):

'TestString'.split('').reduce((t, v, k) => t + (k === 0 ? v.toLowerCase() : v), '');

Twitter Bootstrap v3.0.3 has a class: center-block

Center content blocks

Set an element to display: block and center via margin. Available as a mixin and class.

Just need to add a class .center-block in the img tag, looks like this

<div class="container">
  <div class="row">
    <div class="span4"></div>
    <div class="span4"><img class="center-block" src="logo.png" /></div>
    <div class="span4"></div>
  </div>
</div>

In Bootstrap already has css style call .center-block

.center-block {
    display: block;
    margin-left: auto;
    margin-right: auto;
 }

You can see a sample from here

(I don't have reps to comment on ValidURL example; hence post this as an answer.)

While use of protocol relative URLs is not encouraged (The Protocol-relative URL), they do get employed sometimes. To validate such an URL with a regular expression the protocol part could be optional, e.g.:

function isValidURL(str) {
    var pattern = new RegExp('^((https?:)?\\/\\/)?'+ // protocol
        '(?:\\S+(?::\\S*)?@)?' + // authentication
        '((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.)+[a-z]{2,}|'+ // domain name
        '((\\d{1,3}\\.){3}\\d{1,3}))'+ // OR ip (v4) address
        '(\\:\\d+)?(\\/[-a-z\\d%_.~+]*)*'+ // port and path
        '(\\?[;&a-z\\d%_.~+=-]*)?'+ // query string
        '(\\#[-a-z\\d_]*)?$','i'); // fragment locater
    if (!pattern.test(str)) {
        return false;
    } else {
        return true;
    }
}

As others noted, regular expression does not seem to be the best suited approach for validating URLs, though.

Python 3.6

Just to make it clear, you can use f-string formatting. This has almost the same syntax as the format method, but make it a bit nicer.

Example:

print(f'{numvar:.9f}')

More reading about the new f string:

• What's new in Python 3.6 (same link as above)
• PEP official documentation
• Python official documentation
• Really good blog post - talks about performance too

Here is a diagram of the execution times of the various tested methods (from last link above):

TypeScript have a way of validating the type of a variable in runtime. You can add a validating function that returns a type predicate. So you can call this function inside an if statement, and be sure that all the code inside that block is safe to use as the type you think it is.

Example from the TypeScript docs:

function isFish(pet: Fish | Bird): pet is Fish {
   return (<Fish>pet).swim !== undefined;
}

// Both calls to 'swim' and 'fly' are now okay.
if (isFish(pet)) {
  pet.swim();
}
else {
  pet.fly();
}

See more at: https://www.typescriptlang.org/docs/handbook/advanced-types.html

Move the srand call to the start of the program. As you have it now, the time might be the same between two consecutive calls, so the random number generator will start again at the same spot.

ALTER DATABASE name OWNER TO new_owner;

See the Postgresql manual's entry on this for more details.

My /var/log/apache2 folder was 35g and some logs in /var/log totaled to be the other 5g of my 40g hard drive. I cleared out all the *.gz logs and after making sure the other logs werent going to do bad things if I messed with them, i just cleared them too.

echo "clear" > access.log

etc.

The Static variables are come into play once the program execution starts and it remain available till the program execution ends.

The Static variables are created in the Data Segment of the Memory.

Let me explain what is happening here, because it isn't obvious!

First, Stream.max() accepts an instance of Comparator so that items in the stream can be compared against each other to find the minimum or maximum, in some optimal order that you don't need to worry too much about.

So the question is, of course, why is Integer::max accepted? After all it's not a comparator!

The answer is in the way that the new lambda functionality works in Java 8. It relies on a concept which is informally known as "single abstract method" interfaces, or "SAM" interfaces. The idea is that any interface with one abstract method can be automatically implemented by any lambda - or method reference - whose method signature is a match for the one method on the interface. So examining the Comparator interface (simple version):

public Comparator<T> {
    T compare(T o1, T o2);
}

If a method is looking for a Comparator<Integer>, then it's essentially looking for this signature:

int xxx(Integer o1, Integer o2);

I use "xxx" because the method name is not used for matching purposes.

Therefore, both Integer.min(int a, int b) and Integer.max(int a, int b) are close enough that autoboxing will allow this to appear as a Comparator<Integer> in a method context.

This is probably old news by now, but the magic seems to be:

• [ScriptService] attribute on web service class
• [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)] on method
• Content-type: application/json in request

With those pieces in place, a GET request is successful.

For a HTTP POST

• [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)] on method

and on the client side (assuming your webmethod is called MethodName, and it takes a single parameter called searchString):

        $.ajax({
            url: "MyWebService.asmx/MethodName",
            type: "POST",
            contentType: "application/json",
            data: JSON.stringify({ searchString: q }),
            success: function (response) {                  
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(textStatus + ": " + jqXHR.responseText);
            }
        });

Actually Opera doesn't have 5MB limit. It offers to increase limit as applications requires more. User can even choose "Unlimited storage" for a domain.

You can easily test localStorage limits/quota yourself.

All major browsers now include native JSON encoding/decoding.

// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject); 

// To decode (This produces an object)
var obj = JSON.parse(json_str);

Note that only valid JSON data will be encoded. For example:

var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"

Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.

Some JSON resources:

• JSON on Mozilla Developer Network
• JSON on Wikipedia

If you want to apply some condition on form submit then you can use this method

<form onsubmit="return checkEmpData();" method="post" action="process.html">
  <input type="text" border="0" name="submit" />
  <button value="submit">submit</button>
</form>

One thing always keep in mind that method and action attribute write after onsubmit attributes

javascript code

function checkEmpData()
{
  var a = 0;

  if(a != 0)
  {
    return confirm("Do you want to generate attendance?");
  }
   else
   {
      alert('Please Select Employee First');
      return false;
   }  
}

You can do it like this:

uint8_t (*matrix_ptr)[10][20] = &l_matrix;

Unfortunately, all answers so far do not take into account that "a" must not be considered equal to "A" when it comes to sorting.

String[] array = {"b", "A", "C", "B", "a"};

// Approach 1
Arrays.sort(array);
// array is [A, B, C, a, b]

// Approach 2
Arrays.sort(array, String.CASE_INSENSITIVE_ORDER);
// array is [A, a, b, B, C]

// Approach 3
Arrays.sort(array, java.text.Collator.getInstance());
// array is [a, A, b, B, C]

In approach 1 any lower case letters are considered greater than any upper case letters.

Approach 2 makes it worse, since CASE_INSENSITIVE_ORDER considers "a" and "A" equal (comparation result is 0). This makes sorting non-deterministic.

Approach 3 (using a java.text.Collator) is IMHO the only way of doing it correctly, since it considers "a"and "A" not equal, but puts them in the correct order according to the current (or any other desired) Locale.

use below code it helps you....

        BitmapFactory.Options options = new BitmapFactory.Options();

        options.inSampleSize = 4;
        options.inPurgeable = true;
        Bitmap bm = BitmapFactory.decodeFile("your path of image",options);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        bm.compress(Bitmap.CompressFormat.JPEG,40,baos); 


        // bitmap object

        byteImage_photo = baos.toByteArray();

                    //generate base64 string of image

                   String encodedImage =Base64.encodeToString(byteImage_photo,Base64.DEFAULT);

  //send this encoded string to server

What about:

DECLARE @DOB datetime
SET @DOB='19851125'   
SELECT Datepart(yy,convert(date,GETDATE())-@DOB)-1900

Wouldn't that avoid all those rounding, truncating and ofsetting issues?

Well, what I usually do is have my methods that could error-out at runtime take a reference to a NSError pointer. If something does indeed go wrong in that method, I can populate the NSError reference with error data and return nil from the method.

Example:

- (id) endWorldHunger:(id)largeAmountsOfMonies error:(NSError**)error {
    // begin feeding the world's children...
    // it's all going well until....
    if (ohNoImOutOfMonies) {
        // sad, we can't solve world hunger, but we can let people know what went wrong!
        // init dictionary to be used to populate error object
        NSMutableDictionary* details = [NSMutableDictionary dictionary];
        [details setValue:@"ran out of money" forKey:NSLocalizedDescriptionKey];
        // populate the error object with the details
        *error = [NSError errorWithDomain:@"world" code:200 userInfo:details];
        // we couldn't feed the world's children...return nil..sniffle...sniffle
        return nil;
    }
    // wohoo! We fed the world's children. The world is now in lots of debt. But who cares? 
    return YES;
}

We can then use the method like this. Don't even bother to inspect the error object unless the method returns nil:

// initialize NSError object
NSError* error = nil;
// try to feed the world
id yayOrNay = [self endWorldHunger:smallAmountsOfMonies error:&error];
if (!yayOrNay) {
   // inspect error
   NSLog(@"%@", [error localizedDescription]);
}
// otherwise the world has been fed. Wow, your code must rock.

We were able to access the error's localizedDescription because we set a value for NSLocalizedDescriptionKey.

The best place for more information is Apple's documentation. It really is good.

I know I'm a little late to the party, but I did want to throw some interjections. (I would have commented but not enough reputation points yet, so, here's a full answer).

This requires the latest version of VS Code, Azure Repo Extention, and Git to be installed.

Anyone looking to use the new VS Code (or using the preview like myself), when you go to the Settings (Still File -> Preferences -> Settings or CTRL+, ) you'll be looking under User Settings -> Extensions -> Azure Repos.

Then under Tfvc: Location you can paste the location of the executable.

For 2017 it'll be

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

Or for 2019 (Preview)

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

After adding the location, I closed my VS Code (not sure if this was needed) and went my git repo to copy the git URL.

After that, went back into VS Code went to the Command Palette (View -> Command Palette or CTRL+Shift+P) typed Git: Clone pasted my repo:

Selected the location for the repo to be stored. Next was an error that popped up. I proceeded to follow this video which walked me through clicking on the Team button with the exclamation mark on the bottom of your VS Code Screen

Then chose the new method of authentication

Copy by using CTRL+C and then press enter. Your browser will launch a page where you'll enter the code you copied (CTRL+V).

Click Continue

Log in with your Microsoft Credentials and you should see a change on the bottom bar of VS Code.

Cheers!

It's not advisable to use the environment.*.ts files for your API URL configuration. It seems like you should because this mentions the word "environment".

Using this is actually compile-time configuration. If you want to change the API URL, you will need to re-build. That's something you don't want to have to do ... just ask your friendly QA department :)

What you need is runtime configuration, i.e. the app loads its configuration when it starts up.

Some other answers touch on this, but the difference is that the configuration needs to be loaded as soon as the app starts, so that it can be used by a normal service whenever it needs it.

To implement runtime configuration:

1. Add a JSON config file to the /src/assets/ folder (so that is copied on build)
2. Create an AppConfigService to load and distribute the config
3. Load the configuration using an APP_INITIALIZER

1. Add Config file to /src/assets

You could add it to another folder, but you'd need to tell the CLI that it is an asset in the angular.json. Start off using the assets folder:

{
  "apiBaseUrl": "https://development.local/apiUrl"
}

2. Create AppConfigService

This is the service which will be injected whenever you need the config value:

@Injectable({
  providedIn: 'root'
})
export class AppConfigService {

  private appConfig: any;

  constructor(private http: HttpClient) { }

  loadAppConfig() {
    return this.http.get('/assets/config.json')
      .toPromise()
      .then(data => {
        this.appConfig = data;
      });
  }

  // This is an example property ... you can make it however you want.
  get apiBaseUrl() {

    if (!this.appConfig) {
      throw Error('Config file not loaded!');
    }

    return this.appConfig.apiBaseUrl;
  }
}

3. Load the configuration using an APP_INITIALIZER

To allow the AppConfigService to be injected safely, with config fully loaded, we need to load the config at app startup time. Importantly, the initialisation factory function needs to return a Promise so that Angular knows to wait until it finishes resolving before finishing startup:

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule
  ],
  providers: [
    {
      provide: APP_INITIALIZER,
      multi: true,
      deps: [AppConfigService],
      useFactory: (appConfigService: AppConfigService) => {
        return () => {
          //Make sure to return a promise!
          return appConfigService.loadAppConfig();
        };
      }
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Now you can inject it wherever you need to and all the config will be ready to read:

@Component({
  selector: 'app-test',
  templateUrl: './test.component.html',
  styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit {

  apiBaseUrl: string;

  constructor(private appConfigService: AppConfigService) {}

  ngOnInit(): void {
    this.apiBaseUrl = this.appConfigService.apiBaseUrl;
  }

}

I can't say it strongly enough, configuring your API urls as compile-time configuration is an anti-pattern. Use runtime configuration.

In my case, I was getting this error message because I was changed the service's namespace and services tag was pointed to the older namespace. I refreshed the namespace and the error disapear:

<services>
  <service name="My.Namespace.ServiceName"> <!-- Updated name -->
    <endpoint address="" 
              binding="wsHttpBinding" 
              bindingConfiguration="MyBindingConfiguratioName" 
              contract="My.Namespace.Interface" <!-- Updated contract -->
    />
  </service>
</services>

Have you looked into rasdial?

Just incase anyone wanted to do this and finds this in the future, you can use rasdial.exe from command prompt to connect to a VPN network

ie rasdial "VPN NETWORK NAME" "Username" *

it will then prompt for a password, else you can use "username" "password", this is however less secure

I like the simplicity of gilly3's answer, but users will probably be surprised that a month before March 31 is March 3. I chose to implement a version that sticks to the end of the month, so a month before March 28, 29, 30, and 31 will all be Feb 28 when it's not a leap year.

function addMonths(date, months) {_x000D_
  var result = new Date(date),_x000D_
      expectedMonth = ((date.getMonth() + months) % 12 + 12) % 12;_x000D_
  result.setMonth(result.getMonth() + months);_x000D_
  if (result.getMonth() !== expectedMonth) {_x000D_
    result.setDate(0);_x000D_

Here's what you CAN do:

You can attach (to the email) an html document that contains javascript.

Then, when the recipient opens the attachment, their web browser will facilitate the dynamic features you've implemented.

I bet the problem is being shown in this line

SqlDataReader dr3 = com2.ExecuteReader();

I suggest that you execute the first reader and do a dr.Close(); and the iterate historicos, with another loop, performing the com2.ExecuteReader().

public List<string[]> get_dados_historico_verificacao_email_WEB(string email)
    {

        List<string[]> historicos = new List<string[]>();
        conecta();
        sql = "SELECT * FROM historico_verificacao_email WHERE nm_email = '" + email + "' ORDER BY  dt_verificacao_email DESC, hr_verificacao_email DESC"; 
        com = new SqlCommand(sql, conexao);
        SqlDataReader dr = com.ExecuteReader();

        if (dr.HasRows)
        {
            while (dr.Read())
            {
                string[] dados_historico = new string[6];
                dados_historico[0] = dr["nm_email"].ToString();
                dados_historico[1] = dr["dt_verificacao_email"].ToString();
                dados_historico[1] = dados_historico[1].Substring(0, 10);
                //System.Windows.Forms.MessageBox.Show(dados_historico[1]);
                dados_historico[2] = dr["hr_verificacao_email"].ToString();
                dados_historico[3] = dr["ds_tipo_verificacao"].ToString();
                dados_historico[5] = dr["cd_login_usuario"].ToString();
                historicos.Add(dados_historico);
            }

            dr.Close();

            sql = "SELECT COUNT(e.cd_historico_verificacao_email) QT FROM emails_lidos e WHERE e.cd_historico_verificacao_email = '" + dr["cd_historico_verificacao_email"].ToString() + "'";
            tipo_sql = "seleção";
            com2 = new SqlCommand(sql, conexao);

            for(int i = 0 ; i < historicos.Count() ; i++)
            {
                SqlDataReader dr3 = com2.ExecuteReader();
                while (dr3.Read())
                {
                    historicos[i][4] = dr3["QT"].ToString(); //quantidade de emails lidos naquela verificação
                }
                dr3.Close();
            }

        }

        return historicos;

If you want to match starting from the beginning of the word, use:

\b\w{3,}

\b: word boundary

\w: word character

{3,}: three or more times for the word character

You can simply add these lines of codes here to hide a row,

Either you can write border:0 or border-style:hidden; border: none or it will happen the same thing

running these lines of codes can solve the problem easily

This worked for me, within an ASP.NET MVC3 site where I'd left the framework to setup unobtrusive validation etc., in case it's useful to anyone:

$("form").data("validator").settings.ignore = "";

There are possible steps to enable auto increment for a column. I guess the phpMyAdmin version is 3.5.5 but not sure.

Click on Table > Structure tab > Under Action Click Primary (set as primary), click on Change on the pop-up window, scroll left and check A_I. Also make sure you have selected None for Default

Looking at your own answer @Bog, I think you want;

$plugin_dir_path = dirname(__FILE__);

JSBin

Add onClick event to checkbox where you want, like below.

<input type="checkbox" onClick="selectall(this)"/>Select All<br/>
<input type="checkbox" name="foo" value="make">Make<br/>
<input type="checkbox" name="foo" value="model">Model<br/>
<input type="checkbox" name="foo" value="descr">Description<br/>
<input type="checkbox" name="foo" value="startYr">Start Year<br/>
<input type="checkbox" name="foo" value="endYr">End Year<br/>

In JavaScript you can write selectall function as

function selectall(source) {
  checkboxes = document.getElementsByName('foo');
  for(var i=0, n=checkboxes.length;i<n;i++) {
    checkboxes[i].checked = source.checked;
  }
}

please try to install the dependencie with pip, run this command:

sudo pip install -U setuptools

Even if the hash is not for security, you can use sha instead of md5. In my opinion, the people should forget about md5 for now, it's in the past!

The normal nodejs sha256 is deprecated. So, you have two alternatives for now:

var shajs = require('sha.js')  - https://www.npmjs.com/package/sha.js (used by Browserify)

var hash = require('hash.js')  - https://github.com/indutny/hash.js

I prefer using shajs instead of hash, because I consider sha the best hash function nowadays and you don't need a different hash function for now. So to get some hash in hex you should do something like the following:

sha256.update('hello').digest('hex')

• os.remove() removes a file.

• os.rmdir() removes an empty directory.

• shutil.rmtree() deletes a directory and all its contents.

Path objects from the Python 3.4+ pathlib module also expose these instance methods:

• pathlib.Path.unlink() removes a file or symbolic link.

• pathlib.Path.rmdir() removes an empty directory.

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

Javascript alternatives

Modernizr

Modernizr runs quickly on page load to detect features; it then creates a JavaScript object with the results, and adds classes to the html element

User agent selection

The Javascript:

var b = document.documentElement;
        b.setAttribute('data-useragent',  navigator.userAgent);
        b.setAttribute('data-platform', navigator.platform );
        b.className += ((!!('ontouchstart' in window) || !!('onmsgesturechange' in window))?' touch':'');

Adds (e.g) the below to the html element:

data-useragent='Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C)'
data-platform='Win32'

Allowing very targetted CSS selectors, e.g.:

html[data-useragent*='Chrome/13.0'] .nav{
    background:url(img/radial_grad.png) center bottom no-repeat;
}

Footnote

If possible, avoid browser targeting. Identify and fix any issue(s) you identify. Support progressive enhancement and graceful degradation. With that in mind, this is an 'ideal world' scenario not always obtainable in a production environment, as such- the above should help provide some good options.

I installed xampp bundle with apache, php and mysql in ubuntu. There my.cnf file is located in /opt/lampp/etc/ folder. Hope it'll help somebody.

The other way is to use BinaryPrimitives like so

byte[] intBytes = BitConverter.GetBytes(123); int actual = BinaryPrimitives.ReadInt32LittleEndian(intBytes);

In simple terms, environment variables are set when you open a new shell session. At any time if you change any of the variable values, the shell has no way of picking that change. that means the changes you made become effective in new shell sessions. The export command, on the other hand, provides the ability to update the current shell session about the change you made to the exported variable. You don't have to wait until new shell session to use the value of the variable you changed.

May or may not be accurate, but according to this site: http://www.htmlite.com/mysql003.php.

BLOB A string with a maximum length of 65535 characters.

The MySQL manual says:

The maximum size of a BLOB or TEXT object is determined by its type, but the largest value you actually can transmit between the client and server is determined by the amount of available memory and the size of the communications buffers

I think the first site gets their answers from interpreting the MySQL manual, per http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html

This might help:

select * from tbl where col like '[ABC-XYZ-PQR]%'

I've used this in SQL Server 2005 and it worked.

var requestedURL = "https://accounts.google.com/o/oauth2/token?code=" + code + "&client_id=" + client_id + "&client_secret=" + client_secret + "&redirect_uri=" + redirect_uri + "&grant_type=authorization_code";
HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(requestedURL);
authRequest.ContentType = "application/x-www-form-urlencoded";
authRequest.Method = "POST";
//Set content length to 0
authRequest.ContentLength = 0;
WebResponse authResponseTwitter = authRequest.GetResponse();

The ContentLength property contains the value to send as the Content-length HTTP header with the request.

Any value other than -1 in the ContentLength property indicates that the request uploads data and that only methods that upload data are allowed to be set in the Method property.

After the ContentLength property is set to a value, that number of bytes must be written to the request stream that is returned by calling the GetRequestStream method or both the BeginGetRequestStream and the EndGetRequestStream methods.

To retrieve all radio buttons values in JavaScript array use following jQuery code :

var values = jQuery('input:checkbox:checked.group1').map(function () {
    return this.value;
}).get();

Use int function with second parameter 16, to convert a hex string to an integer. Finally, use hex function to convert it back to a hexadecimal number.

print hex(int("0xAD4", 16) + int("0x200", 16)) # 0xcd4

Instead you could directly do

print hex(int("0xAD4", 16) + 0x200) # 0xcd4

If you want to know the list of procedures you can run the following command -

show procedure status;

It will give you the list of procedures and their definers Then you can run the show create procedure <procedurename>;

Also you can use DownloadFileAsync method in WebClient class. It downloads to a local file the resource with the specified URI. Also this method does not block the calling thread.

Sample:

    webClient.DownloadFileAsync(new Uri("http://www.example.com/file/test.jpg"), "test.jpg");

I had the same problem once this is how I solved it.

Suppose I want 12 delays with an interval of 2 secs

    function animate(i){
         myVar=setTimeout(function(){
            alert(i);
            if(i==12){
              clearTimeout(myVar);
              return;
            }
           animate(i+1)
         },2000)
    }

    var i=1; //i is the start point 1 to 12 that is
    animate(i); //1,2,3,4..12 will be alerted with 2 sec delay

Okay, just to clarify things that have already been posted.

You should have the directory com, containing the directory company, containing the directory example, containing the file MyClass.java.

From the folder containing com, run:

$ javac com\company\example\MyClass.java

Then:

$ java com.company.example.MyClass
Hello from MyClass!

These must both be done from the root of the source tree. Otherwise, javac and java won't be able to find any other packages (in fact, java wouldn't even be able to run MyClass).

A short example

I created the folders "testpackage" and "testpackage2". Inside testpackage, I created TestPackageClass.java containing the following code:

package testpackage;

import testpackage2.MyClass;

public class TestPackageClass {
    public static void main(String[] args) {
        System.out.println("Hello from testpackage.TestPackageClass!");
        System.out.println("Now accessing " + MyClass.NAME);
    }
}

Inside testpackage2, I created MyClass.java containing the following code:

package testpackage2;
public class MyClass {
    public static String NAME = "testpackage2.MyClass";
}

From the directory containing the two new folders, I ran:

C:\examples>javac testpackage\*.java

C:\examples>javac testpackage2\*.java

Then:

C:\examples>java testpackage.TestPackageClass
Hello from testpackage.TestPackageClass!
Now accessing testpackage2.MyClass

Does that make things any clearer?

• First, Download MySQL connector jar file, This is the latest jar file as of today [mysql-connector-java-8.0.21].

• Add the Jar file to your workspace [build path].

• Then Create a new Connection object from the DriverManager class, so you could use this Connection object to execute queries.

• Define the database name, userName, and Password for your connection.

• Use the resultSet to get the data based one the column name from your database table.

Sample code is here:

public class JdbcMySQLExample{

public static void main(String[] args) {

    String url = "jdbc:mysql://localhost:3306/YOUR_DB_NAME?useSSL=false";
    String user = "root";
    String password = "root";
    
    String query = "SELECT * from YOUR_TABLE_NAME";

    try (Connection con = DriverManager.getConnection(url, user, password);
        Statement st = con.createStatement();
        ResultSet rs = st.executeQuery(query)) {

        if (rs.next()) {
            
            System.out.println(rs.getString(1));
        }

    } catch (SQLException ex) {
          System.out.println(ex);
       
    } 
}

You can try out this code. Since you cannot override valueOf method you have to define a custom method (getEnum in the sample code below) which returns the value that you need and change your client to use this method instead.

public enum RandomEnum {

    StartHere("Start Here"),
    StopHere("Stop Here");

    private String value;

    RandomEnum(String value) {
        this.value = value;
    }

    public String getValue() {
        return value;
    }

    @Override
    public String toString() {
        return this.getValue();
    }

    public static RandomEnum getEnum(String value) {
        for(RandomEnum v : values())
            if(v.getValue().equalsIgnoreCase(value)) return v;
        throw new IllegalArgumentException();
    }
}

You can use SoapUI: http://www.soapui.org/ This is a generally handy program. Make a new project, connect to the WSDL link, then right click on the project and say "Show interface viewer". Under "Schemas" on the left you can see the XSD.

SoapUI can do many things though!

If you use action.BeginInvoke(), you have to call EndInvoke somewhere - else the framework has to hold the result of the async call on the heap, resulting in a memory leak.

If you don't want to jump to C# 5 with the async/await keywords, you can just use the Task Parallels library in .Net 4. It's much, much nicer than using BeginInvoke/EndInvoke, and gives a clean way to fire-and-forget for async jobs:

using System.Threading.Tasks;
...
void Foo(){}
...
new Task(Foo).Start();

If you have methods to call that take parameters, you can use a lambda to simplify the call without having to create delegates:

void Foo2(int x, string y)
{
    return;
}
...
new Task(() => { Foo2(42, "life, the universe, and everything");}).Start();

I'm pretty sure (but admittedly not positive) that the C# 5 async/await syntax is just syntactic sugar around the Task library.

The important thing to note here is that the mime type is not the same as the file extension. Sometimes, however, they have the same value.

https://www.iana.org/assignments/media-types/media-types.xhtml includes a list of registered Mime types, though there is nothing stopping you from making up your own, as long as you are at both the sending and the receiving end. Here is where Microsoft comes in to the picture.

Where there is a lot of confusion is the fact that operating systems have their own way of identifying file types by using the tail end of the file name, referred to as the extension. In modern operating systems, the whole name is one long string, but in more primitive operating systems, it is treated as a separate attribute.

The OS which caused the confusion is MSDOS, which had limited the extension to 3 characters. This limitation is inherited to this day in devices, such as SD cards, which still store data in the same way.

One side effect of this limitation is that some file extensions, such as .gif match their Mime Type, image/gif, while others are compromised. This includes image/jpeg whose extension is shortened to .jpg. Even in modern Windows, where the limitation is lifted, Microsoft never let the past go, and so the file extension is still the shortened version.

Given that that:

1. File Extensions are not File Types
2. Historically, some operating systems had serious file name limitations
3. Some operating systems will just go ahead and make up their own rules

The short answer is:

• Technically, there is no such thing as image/jpg, so the answer is that it is not the same as image/jpeg
• That won’t stop some operating systems and software from treating it as if it is the same

While we’re at it …

Legacy versions of Internet Explorer took the liberty of uploading jpeg files with the Mime Type of image/pjpeg, which, of course, just means more work for everybody else. They also uploaded png files as image/x-png.

If you are inside of Spring bean (in this case @Controller bean) you shouldn't use Spring context instance at all. Just autowire className bean directly.

BTW, avoid using field injection as it's considered as bad practice.

In case of trying to find tool to make your 2-space indented python script to a tab indented version, just use this online tool:

If the key field is nullable, then you can also set the value to null before attempting to delete it:

cursor.execute("UPDATE myapp_item SET myapp_style_id = NULL WHERE n = %s", n)
transaction.commit_unless_managed() 

cursor.execute("UPDATE myapp_style SET myapp_item_id = NULL WHERE n = %s", n)
transaction.commit_unless_managed()

cursor.execute("DELETE FROM myapp_item WHERE n = %s", n)
transaction.commit_unless_managed()

cursor.execute("DELETE FROM myapp_style WHERE n = %s", n)
transaction.commit_unless_managed()

Did you set the section header height in the viewDidLoad?

self.tableView.sectionHeaderHeight = 70

Plus you should replace

self.view.addSubview(view)

by

view.addSubview(label)

Finally you have to check your frames

let view = UIView(frame: CGRect.zeroRect)

and eventually the desired text color as it seems to be currently white on white.

As I don't want to introduce alien-like new C++ syntax, and I simply want to build up on existing primitives, the below snippets seems to work:

#include <vector>
#include <iostream>

int main (int argc,char *argv[])
{
    std::vector<int> arr{1,2,3,4,5};
    std::vector<int>::iterator it;

    // iterate forward
    for (it = arr.begin(); it != arr.end(); it++) {
        std::cout << *it << " ";
    }

    std::cout << "\n************\n";
 
    if (arr.size() > 0) {
        // iterate backward, simple Joe version
        it = arr.end() - 1;
        while (it != arr.begin()) {
            std::cout << *it << " ";
            it--;
        }
        std::cout << *it << " ";
    } 

    // iterate backwards, the C++ way
    std::vector<int>::reverse_iterator rit;
    for (rit = arr.rbegin(); rit != arr.rend(); rit++) {
        std::cout << *rit << " ";
    }

    return 0;
}

You'd have to check each value against in_array:

$a=array();
// organize the array by cusip
foreach($array as $k=>$v){
    foreach($v as $key=>$value){
        if(!in_array($value, $a)){
        $a[]=$value;
        }
    }
}

in my case it was a cross-origin frame and wasn't loading sometimes. the solution that worked for me is: if it's loaded successfully then if you try this code:

var iframe = document.getElementsByTagName('iframe')[0];
console.log(iframe.contentDocument);

it won't allow you to access contentDocument and throw a cross-origin error however if frame is not loaded successfully then contentDocument will return a #document object

You need to enable change tracking.

• Right click on your database and click Properties
• Click change tracking and make it enable
• Go Tools -> Options -> Designer again and uncheck it.

Get-Content (alias: gc) is your usual option for reading a text file. You can then filter further:

gc log.txt | select -first 10 # head
gc -TotalCount 10 log.txt     # also head
gc log.txt | select -last 10  # tail
gc -Tail 10 log.txt           # also tail (since PSv3), also much faster than above option
gc log.txt | more             # or less if you have it installed
gc log.txt | %{ $_ -replace '\d+', '($0)' }         # sed

This works well enough for small files, larger ones (more than a few MiB) are probably a bit slow.

The PowerShell Community Extensions include some cmdlets for specialised file stuff (e.g. Get-FileTail).

Can't you style the forms themselves? Then, style the divs accordingly.

form
{

}

You can always overrule inherited styles by making it important:

form

}

It can also be due to a duplicate entry in any of the tables that are used.

I used google colab to run my models and everything was perfect untill i used inline tesorboard. With tensorboard inline, I had the same issue of "Module 'tensorflow' has no attribute 'contrib'".

Let's assume you can't change the input type, or even the src. You ONLY have css to play with.

If you know the height you want, and you have the url of a background image you want to use instead, you're in luck.

Set the height to zero and padding-top to the height you want. That'll shove the original image out of sight, giving you a perfectly clean space to show your css background-image.

Works in Chrome. No idea if it works in IE. Barely anything clever does, so probably not.

#daft {_x000D_
  height: 0;_x000D_
  padding-top: 100px;_x000D_
  width: 100px;_x000D_
  background-image: url(clever.jpg);_x000D_
}

<input type="image" src="daft.jpg" id="daft">

this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -

1. Used the cmd to install python and flask after creating environment as suggested above.

2. Followed this answer.

3. As suggested above, went to Run -> Edit Configurations and changed the environment there as well as in (2).

Obviously kept the correct python interpreter (the one in the environment) everywhere.

cd somedir
npm install .

or

npm install path/to/somedir

somedir must contain the package.json inside it.

It knows about git too:

npm install git://github.com/visionmedia/express.git

do in your shell: $ env |grep LANG

This will probably show that your shell is not using a utf-8 locale.

On instances of object you also have the:

__class__

attribute. Here is a sample taken from Python 3.3 console

>>> str = "str"
>>> str.__class__
<class 'str'>
>>> i = 2
>>> i.__class__
<class 'int'>
>>> class Test():
...     pass
...
>>> a = Test()
>>> a.__class__
<class '__main__.Test'>

Beware that in python 3.x and in New-Style classes (aviable optionally from Python 2.6) class and type have been merged and this can sometime lead to unexpected results. Mainly for this reason my favorite way of testing types/classes is to the isinstance built in function.
