You can open the file using the ios::ate flag (and ios::binary flag), so the tellg() function will give you directly the file size:

ifstream file( "example.txt", ios::binary | ios::ate);
return file.tellg();

It is possible to play a local video file.

<input type="file" accept="video/*"/>
<video controls autoplay></video>

When a file is selected via the input element:

1. 'change' event is fired
2. Get the first File object from the input.files FileList
3. Make an object URL that points to the File object
4. Set the object URL to the video.src property

5. Lean back and watch :)

You can set content view (or design) of an activity. For example you can do it like this too :

public void onCreate(Bundle savedinstanceState) {
    super.onCreate(savedinstanceState);

    Button testButon = new Button(this);

    setContentView(testButon);   
}

Strings are hard work in C.

#include <stdio.h>

int main()
{
   int i;
   char buf[12];

   for (i = 0; i < 100; i++) {
      snprintf(buf, 12, "pre_%d_suff", i); // puts string into buffer
      printf("%s\n", buf); // outputs so you can see it
   }
}

The 12 is enough bytes to store the text "pre_", the text "_suff", a string of up to two characters ("99") and the NULL terminator that goes on the end of C string buffers.

This will tell you how to use snprintf, but I suggest a good C book!

Since position: absolute; and viewport width were no options in my special case, there is another quick solution to solve the problem. The only condition is, that overflow in x-direction is not necessary for your website.

You can define negative margins for your element:

#help_panel {
    margin-left: -9999px;
    margin-right: -9999px;
}

But since we get overflow doing this, we have to avoid overflow in x-direction globally e.g. for body:

body {
    overflow-x: hidden;
}

You can set padding to choose the size of your content.

Note that this solution does not bring 100% width for content, but it is helpful in cases where you need e.g. a background color which has full width with a content still depending on container.

For Laravel 4: {!! for a double curly brace { {
and for Laravel 5 & above version: you may replace {!! by {{ and !!} by }} in higher-end version

If you have placed JavaScript in a custom defined directory.
For instance, if your jQuery-2.2.0.min.js is placed under the directory resources/views/admin/plugins/js/ then from the *.blade.php you will be able to add at the end of the section as

<script src="{!! asset('resources/views/admin/plugins/js/jQuery-2.2.0.min.js') !!}"></script>

Since Higher-End version supports Lower-End version also and but not vice-versa

This is more for someone Searching for a result, than the original post-er. This worked for me...

declare @value varchar(max) = 'sad';
select sum(cast(iif(isnumeric(@value) = 1, @value, 0) as bigint));

returns 0

declare @value varchar(max) = '3';
select sum(cast(iif(isnumeric(@value) = 1, @value, 0) as bigint));

returns 3

This answer applies to Jackson versions prior to 2+ (originally written for 1.8). See @SupunSameera's answer for a version that works with newer versions of Jackson.

The JSON terms for "node name" is "key." Since JsonNode#iterator() does not include keys, you need to iterate differently:

for (Map.Entry<String, JsonNode> elt : rootNode.fields())
{
    if ("foo".equals(elt.getKey()))
    {
        // bar
    }
}

If you only need to see the keys, you can simplify things a bit with JsonNode#fieldNames():

for (String key : rootNode.fieldNames())
{
    if ("foo".equals(key))
    {
        // bar
    }
}

And if you just want to find the node with key "foo", you can access it directly. This will yield better performance (constant-time lookup) and cleaner/clearer code than using a loop:

JsonNode foo = rootNode.get("foo");
if (foo != null)
{
    // frob that widget
}

From MSDN:

C#, through the .NET Framework common language runtime (CLR), automatically releases the memory used to store objects that are no longer required. The release of memory is non-deterministic; memory is released whenever the CLR decides to perform garbage collection. However, it is usually best to release limited resources such as file handles and network connections as quickly as possible.

The using statement allows the programmer to specify when objects that use resources should release them. The object provided to the using statement must implement the IDisposable interface. This interface provides the Dispose method, which should release the object's resources.

In other words, the using statement tells .NET to release the object specified in the using block once it is no longer needed.

Global Library Installation as Official documentation here

1. Install from npm:

   npm install jquery --save

2. Add needed script files to scripts:

   "scripts": [ "node_modules/jquery/dist/jquery.slim.js" ],

Restart server if you're running it, and it should be working on your app.

If you want to use inside single component use import $ from 'jquery'; inside your component

I was asking the same question just now after a quick google I found that There is a pair class in .NET except its in the System.Web.UI ^ ~ ^ (http://msdn.microsoft.com/en-us/library/system.web.ui.pair.aspx) goodness knows why they put it there instead of the collections framework

Python does not have these operators, but if you really need them you can write a function having the same functionality.

def PreIncrement(name, local={}):
    #Equivalent to ++name
    if name in local:
        local[name]+=1
        return local[name]
    globals()[name]+=1
    return globals()[name]

def PostIncrement(name, local={}):
    #Equivalent to name++
    if name in local:
        local[name]+=1
        return local[name]-1
    globals()[name]+=1
    return globals()[name]-1

Usage:

x = 1
y = PreIncrement('x') #y and x are both 2
a = 1
b = PostIncrement('a') #b is 1 and a is 2

Inside a function you have to add locals() as a second argument if you want to change local variable, otherwise it will try to change global.

x = 1
def test():
    x = 10
    y = PreIncrement('x') #y will be 2, local x will be still 10 and global x will be changed to 2
    z = PreIncrement('x', locals()) #z will be 11, local x will be 11 and global x will be unaltered
test()

Also with these functions you can do:

x = 1
print(PreIncrement('x'))   #print(x+=1) is illegal!

But in my opinion following approach is much clearer:

x = 1
x+=1
print(x)

Decrement operators:

def PreDecrement(name, local={}):
    #Equivalent to --name
    if name in local:
        local[name]-=1
        return local[name]
    globals()[name]-=1
    return globals()[name]

def PostDecrement(name, local={}):
    #Equivalent to name--
    if name in local:
        local[name]-=1
        return local[name]+1
    globals()[name]-=1
    return globals()[name]+1

I used these functions in my module translating javascript to python.

You can use a library called underscore js. It gives a nice wrapper on the bind method and is a much cleaner syntax as well. Letting you execute the function in the specified scope.

http://underscorejs.org/#bind

_.bind(function, scope, *arguments)

You can disable animation, transition, trasforms for all of element in page with this css code

var style = document.createElement('style');
style.type = 'text/css';
style.innerHTML = '* {' +
'/*CSS transitions*/' +
' -o-transition-property: none !important;' +
' -moz-transition-property: none !important;' +
' -ms-transition-property: none !important;' +
' -webkit-transition-property: none !important;' +
'  transition-property: none !important;' +
'/*CSS transforms*/' +
'  -o-transform: none !important;' +
' -moz-transform: none !important;' +
'   -ms-transform: none !important;' +
'  -webkit-transform: none !important;' +
'   transform: none !important;' +
'  /*CSS animations*/' +
'   -webkit-animation: none !important;' +
'   -moz-animation: none !important;' +
'   -o-animation: none !important;' +
'   -ms-animation: none !important;' +
'   animation: none !important;}';
   document.getElementsByTagName('head')[0].appendChild(style);

Instead of redirecting System.out, I would refactor the class that uses System.out.println() by passing a PrintStream as a collaborator and then using System.out in production and a Test Spy in the test. That is, use Dependency Injection to eliminate the direct use of the standard output stream.

In Production

ConsoleWriter writer = new ConsoleWriter(System.out));

In the Test

ByteArrayOutputStream outSpy = new ByteArrayOutputStream();
ConsoleWriter writer = new ConsoleWriter(new PrintStream(outSpy));
writer.printSomething();
assertThat(outSpy.toString(), is("expected output"));

Discussion

This way the class under test becomes testable by a simple refactoring, without having the need for indirect redirection of the standard output or obscure interception with a system rule.

I have the second solution:

1. unzip https://dl.dropboxusercontent.com/u/16403954/android-21.zip to sdk\platforms\

2. change build.gradle like

   compileSdkVersion 21
   buildToolsVersion "20.0.0"
   
   defaultConfig {
       applicationId "package.name"
       minSdkVersion 10
       targetSdkVersion 21
       versionCode 1
       versionName "1.0"
   }
   

3. add

   <uses-sdk tools:node="replace" /> 
   

   in Manifest with xmlns:tools="schemas.android.com/tools";

4. Go to sdk\extras\android\m2repository\com\android\support\support-v4\21.0.0-rc1\

unpack support-v4-21.0.0-rc1.aar and edit AndroidManifest.xml like

from

<uses-sdk
        android:minSdkVersion="L"
        android:targetSdkVersion="L" />

to

<uses-sdk
        android:minSdkVersion="4"
        android:targetSdkVersion="21" />

P.S. You can do this with all support libraries that need.

Here is a way to check is virtualization is enabled or disabled by the firmware as suggested by this link in parallels.com.

How to check that Intel VT-x is supported in CPU:

1. Open Terminal application from Application/Utilities

2. Copy/paste command bellow

sysctl -a | grep machdep.cpu.features

3. You may see output similar to:

Mac:~ user$ sysctl -a | grep machdep.cpu.features kern.exec: unknown type returned machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON VMX EST TM2 TPR PDCM

If you see VMX entry then CPU supports Intel VT-x feature, but it still may be disabled.

Refer to this link on Apple.com to enable hardware support for virtualization:

Try this;

@media print{ @page { margin-top: 30px; margin-bottom: 30px;}}

Yet another node based simple command line server

https://github.com/greggman/servez-cli

Written partly in response to http-server having issues, particularly on windows.

installation

Install node.js then

npm install -g servez

usage

servez [options] [path]

With no path it serves the current folder.

By default it serves index.html for folder paths if it exists. It serves a directory listing for folders otherwise. It also serves CORS headers. You can optionally turn on basic authentication with --username=somename --password=somepass and you can serve https.

This works for me :

$scope.array1 = $scope.array1.concat(array2)

In your case it would be :

$scope.actions.data = $scope.actions.data.concat(data)

This answer relates to the questions asked in the comments of the OP's post:

To force a view to appear in a given oriention put the following in viewWillAppear:

UIApplication* application = [UIApplication sharedApplication];
if (application.statusBarOrientation != UIInterfaceOrientationPortrait)
{
    UIViewController *c = [[UIViewController alloc]init];
    [self presentModalViewController:c animated:NO];
    [self dismissModalViewControllerAnimated:NO];
}

It's a bit of a hack, but this forces the UIViewController to be presented in portrait even if the previous controller was landscape

UPDATE for iOS7

The methods above are now deprecated, so for iOS 7 use the following:

UIApplication* application = [UIApplication sharedApplication];
if (application.statusBarOrientation != UIInterfaceOrientationPortrait)
{
     UIViewController *c = [[UIViewController alloc]init];
     [c.view setBackgroundColor:[UIColor redColor]];
     [self.navigationController presentViewController:c animated:NO completion:^{
            [self.navigationController dismissViewControllerAnimated:YES completion:^{
            }];
     }];
}

Interestingly, at the time of writing, either the present or dismiss must be animated. If neither are, then you will get a white screen. No idea why this makes it work, but it does! The visual effect is different depending on which is animated.

For me on AIX, it worked as follows:

Here's a light-weight solution, doing only what OP asked, including highlighting but nothing else: How can I pretty-print JSON using JavaScript?

UPDATE 2018: C++20 will come with templated and conceptualized lambdas. The feature has already been integrated into the standard draft.

UPDATE 2014: C++14 has been released this year and now provides Polymorphic lambdas with the same syntax as in this example. Some major compilers already implement it.

At it stands (in C++11), sadly no. Polymorphic lambdas would be excellent in terms of flexibility and power.

The original reason they ended up being monomorphic was because of concepts. Concepts made this code situation difficult:

template <Constraint T>
void foo(T x)
{
    auto bar = [](auto x){}; // imaginary syntax
}

In a constrained template you can only call other constrained templates. (Otherwise the constraints couldn't be checked.) Can foo invoke bar(x)? What constraints does the lambda have (the parameter for it is just a template, after all)?

Concepts weren't ready to tackle this sort of thing; it'd require more stuff like late_check (where the concept wasn't checked until invoked) and stuff. Simpler was just to drop it all and stick to monomorphic lambdas.

However, with the removal of concepts from C++0x, polymorphic lambdas become a simple proposition again. However, I can't find any proposals for it. :(

Like this:

>>> structTime = time.localtime()
>>> datetime.datetime(*structTime[:6])
datetime.datetime(2009, 11, 8, 20, 32, 35)

Your system likely does not provide the ncurses library at the version android studio uses. My arch linux install only had ncurses 6 but android studio needs version 5. You could check if your distribution has a compatability package, or use the solution that Rahmat Aligos suggested.

Here is an answer for Python 3.8 and OpenPyXL 3.0.0.

I tried to avoid using the get_column_letter function but failed.

This solution uses the newly introduced assignment expressions aka "walrus operator":

import openpyxl
from openpyxl.utils import get_column_letter

workbook = openpyxl.load_workbook("myxlfile.xlsx")

worksheet = workbook["Sheet1"]

MIN_WIDTH = 10
for i, column_cells in enumerate(worksheet.columns, start=1):
    width = (
        length
        if (length := max(len(str(cell_value) if (cell_value := cell.value) is not None else "")
                          for cell in column_cells)) >= MIN_WIDTH
        else MIN_WIDTH
    )
    worksheet.column_dimensions[get_column_letter(i)].width = width

If you are using oracle... STRING will be created as VARCHAR(255) column and TEXT, as a CLOB.

NATIVE_DATABASE_TYPES = {
    primary_key: "NUMBER(38) NOT NULL PRIMARY KEY",
    string: { name: "VARCHAR2", limit: 255 },
    text: { name: "CLOB" },
    ntext: { name: "NCLOB" },
    integer: { name: "NUMBER", limit: 38 },
    float: { name: "BINARY_FLOAT" },
    decimal: { name: "DECIMAL" },
    datetime: { name: "TIMESTAMP" },
    timestamp: { name: "TIMESTAMP" },
    timestamptz: { name: "TIMESTAMP WITH TIME ZONE" },
    timestampltz: { name: "TIMESTAMP WITH LOCAL TIME ZONE" },
    time: { name: "TIMESTAMP" },
    date: { name: "DATE" },
    binary: { name: "BLOB" },
    boolean: { name: "NUMBER", limit: 1 },
    raw: { name: "RAW", limit: 2000 },
    bigint: { name: "NUMBER", limit: 19 }
}

It is easy if you are using django version 3.1 and above

def login_view(request):
    if(request.POST):
        yourForm= YourForm(request.POST)
        itemValue = yourForm['your_filed_name'].value()
        # Check if you get the value
        return HttpResponse(itemValue )
    else:
        return render(request, "base.html")

Simplest way - just put in the Eclipse plugins folder. You can start Eclipse with the -clean option to make sure Eclipse cleans its' plugins cache and sees the new plugin.

In general, it is far more recommended to install plugins using proper update sites.

If you're creating hundreds of thousands of hash maps, you're probably using far more than you actually need; unless you're working with large files or graphics, storing simple data shouldn't overflow the Java memory limit.

You should try and rethink your algorithm. In this case, I would offer more help on that subject, but I can't give any information until you provide more about the context of the problem.

Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....

what difference does this make?

For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript method:

Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _ 
"document.forms[0]['TextBox1'].focus();", True)

This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.

But, if instead it was written like this (using the RegisterClientScriptBlock method):

Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)

Focus will not get to the textbox control and a JavaScript error will be generated on the page

The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.

I am not able to add a comment to M. Kiewisch since I do not have enough reputation points (only have 41 but need more than 50 to comment).

Anyway, just want to point out that M. Kiewisch solution does not work as is and may need more tweaking. Consider for example

>>> df = pd.DataFrame({'a': [1, 2, 3, 5], 'b': [4, np.NaN, 6, 4]})
>>> df
   a    b
0  1  4.0
1  2  NaN
2  3  6.0
3  5  4.0
>>> df.groupby(['b']).sum()
     a
b
4.0  6
6.0  3
>>> df.astype(str).groupby(['b']).sum()
      a
b
4.0  15
6.0   3
nan   2

which shows that for group b=4.0, the corresponding value is 15 instead of 6. Here it is just concatenating 1 and 5 as strings instead of adding it as numbers.

Use this html code it will surely help you

<input type="button" value="NEXT"  onclick="document.write('<?php //call a function here ex- 'fun();' ?>');" />

one limitation is that it is taking more time to run so wait for few seconds it will work

function DeletePersonel(id) {

    var data = new FormData();
    data.append("__RequestVerificationToken", "@HtmlHelper.GetAntiForgeryToken()");

    $.ajax({
        type: 'POST',
        url: '/Personel/Delete/' + id,
        data: data,
        cache: false,
        processData: false,
        contentType: false,
        success: function (result) {
        }
    });
}

public static class HtmlHelper {
    public static string GetAntiForgeryToken() {
        System.Text.RegularExpressions.Match value = 
                System.Text.RegularExpressions.Regex.Match(System.Web.Helpers.AntiForgery.GetHtml().ToString(), 
                        "(?:value=\")(.*)(?:\")");
        if (value.Success) {
            return value.Groups[1].Value;
        }
        return "";
    }
}

you can customize twitter bootstrap css file, open the bootstrap.css file on a text editor, and change the font-family with your font name and SAVE it.

OR got to http://getbootstrap.com/customize/ and make a customized twitter bootstrap

Just for future reference, if you already have a boolean column and you just want to add a default do:

ALTER TABLE users
  ALTER COLUMN priv_user SET DEFAULT false;

If you want to do it for particular column, then you can also use this

length(which(is.na(airquality[1])==T))

On windows you can use a graphic interface of scp using winSCP. A nice free software that implements SFTP protocol.

I had a similiar problem but ./sdkmanager --licenses didnt work. I follow this thread and "obladors" comment gave me the solution: https://github.com/oblador/react-native-vector-icons/issues/527

What eventually solved my problem was: Running ./sdkmanager "build-tools;23.0.1"

Change 23.0.1 with your version

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

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

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

In my experience String.fromCharCode(e.keyCode) is unreliable. String.fromCharCode expects unicode charcodes as an argument; e.keyCode returns javascript keycodes. Javascript keycodes and unicode charcodes are not the same thing! In particular, the numberpad keys return a different keycode from the ordinary number keys (since they are different keys) while the same keycode is returned for both upper and lowercase letters (you pressed the same key in both cases), despite them having different charcodes.

For example, the ordinary number key 1 generates an event with keycode 49 while numberpad key 1 (with Numlock on) generates keycode 97. Used with String.fromCharCode we get the following:

String.fromCharCode(49) returns "1"
String.fromCharCode(97) returns "a"

String.fromCharCode expects unicode charcodes, not javascript keycodes. The key a generates an event with a keycode of 65, independentant of the case of the character it would generate (there is also a modifier for if the Shift key is pressed, etc. in the event). The character a has a unicode charcode of 61 while the character A has a charcode of 41 (according to, for example, http://www.utf8-chartable.de/). However, those are hex values, converting to decimal gives us a charcode of 65 for "A" and 97 for "a".[1] This is consistent with what we get from String.fromCharCode for these values.

My own requirement was limited to processing numbers and ordinary letters (accepting or rejecting depending on the position in the string) and letting control characters (F-keys, Ctrl-something) through. Thus I can check for the control characters, if it's not a control character I check against a range and only then do I need to get the actual character. Given I'm not worried about case (I change all letters to uppercase anyway) and have already limited the range of keycodes, I only have to worry about the numberpad keys. The following suffices for that:

String.fromCharCode((96 <= key && key <= 105)? key-48 : key)

More generally, a function to reliably return the character from a charcode would be great (maybe as a jQuery plugin), but I don't have time to write it just now. Sorry.

I'd also mention e.which (if you're using jQuery) which normalizes e.keyCode and e.charCode, so that you don't need to worry about what sort of key was pressed. The problem with combining it with String.fromCharCode remains.

[1] I was confused for a while -. all the docs say that String.fromCharCode expects a unicode charcode, while in practice it seemed to work for ASCII charcodes, but that was I think due to the need to convert to decimal from hex, combined with the fact that ASCII charcodes and unicode decimal charcodes overlap for ordinary latin letters.

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

No, it's not like any of those things. It's simply the dynamic replacement of attributes at runtime.

For instance, consider a class that has a method get_data. This method does an external lookup (on a database or web API, for example), and various other methods in the class call it. However, in a unit test, you don't want to depend on the external data source - so you dynamically replace the get_data method with a stub that returns some fixed data.

Because Python classes are mutable, and methods are just attributes of the class, you can do this as much as you like - and, in fact, you can even replace classes and functions in a module in exactly the same way.

But, as a commenter pointed out, use caution when monkeypatching:

1. If anything else besides your test logic calls get_data as well, it will also call your monkey-patched replacement rather than the original -- which can be good or bad. Just beware.

2. If some variable or attribute exists that also points to the get_data function by the time you replace it, this alias will not change its meaning and will continue to point to the original get_data. (Why? Python just rebinds the name get_data in your class to some other function object; other name bindings are not impacted at all.)

You could use

kubectl describe pod `hostname` | grep IP | sed -E 's/IP:[[:space:]]+//'

which is based on what @mibbit suggested.

This takes the following facts into account:

• hostname is set to POD's name but this might change in the future
• kubectl was manually placed in the container (possibly when the image was built)
• Kubernetes provides a service account credential to the container implicitly as described in Accessing the Cluster / Accessing the API from a Pod, i.e. /var/run/secrets/kubernetes.io/serviceaccount in the container

If you have callbacks with different parameters you can use templates as follows:
// compile with: g++ -std=c++11 myTemplatedCPPcallbacks.cpp -o myTemplatedCPPcallbacksApp

#include <functional>     // c++11

#include <iostream>        // due to: cout


using std::cout;
using std::endl;

class MyClass
{
    public:
        MyClass();
        static void Callback(MyClass* instance, int x);
    private:
        int private_x;
};

class OtherClass
{
    public:
        OtherClass();
        static void Callback(OtherClass* instance, std::string str);
    private:
        std::string private_str;
};

class EventHandler
{

    public:
        template<typename T, class T2>
        void addHandler(T* owner, T2 arg2)
        {
            cout << "\nHandler added..." << endl;
            //Let's pretend an event just occured
            owner->Callback(owner, arg2);
         }   

};

MyClass::MyClass()
{
    EventHandler* handler;
    private_x = 4;
    handler->addHandler(this, private_x);
}

OtherClass::OtherClass()
{
    EventHandler* handler;
    private_str = "moh ";
    handler->addHandler(this, private_str );
}

void MyClass::Callback(MyClass* instance, int x)
{
    cout << " MyClass::Callback(MyClass* instance, int x) ==> " 
         << 6 + x + instance->private_x << endl;
}

void OtherClass::Callback(OtherClass* instance, std::string private_str)
{
    cout << " OtherClass::Callback(OtherClass* instance, std::string private_str) ==> " 
         << " Hello " << instance->private_str << endl;
}

int main(int argc, char** argv)
{
    EventHandler* handler;
    handler = new EventHandler();
    MyClass* myClass = new MyClass();
    OtherClass* myOtherClass = new OtherClass();
}

Change your TableView Style:

self.tableview = [[UITableView alloc] initwithFrame:frame style:UITableViewStyleGrouped];

As per apple documentation for UITableView:

UITableViewStylePlain- A plain table view. Any section headers or footers are displayed as inline separators and float when the table view is scrolled.

UITableViewStyleGrouped- A table view whose sections present distinct groups of rows. The section headers and footers do not float.

I needed a slightly different result.

I wanted the first word, and what ever came after it - even if it was blank.

str.substr(0, text.indexOf(' ') == -1 ? text.length : text.indexOf(' '));
str.substr(text.indexOf(' ') == -1 ? text.length : text.indexOf(' ') + 1);

so if the input is oneword you get oneword and ''.

If the input is one word and some more you get one and word and some more.

one could also use a fixed lengths vector and access it with indexing

int Lcs(string a, string b) 
{
    int x = a.size() + 1;
    int y = b.size() + 1;

    vector<vector<int>> L(x, vector<int>(y));

    for (int i = 1; i < x; i++)
    {
        for (int j = 1; j < y; j++)
        {
            L[i][j] = a[i - 1] == b[j - 1] ?
                L[i - 1][j - 1] + 1 :
                max(L[i - 1][j], L[i][j - 1]);
        }
    }

    return L[a.size()][b.size()];
}

I could do it like this:

void readfile(const std::string &filepath,std::string &buffer){
    std::ifstream fin(filepath.c_str());
    getline(fin, buffer, char(-1));
    fin.close();
}

If this is something to be frowned upon, please let me know why

You could use the new Python 3.4 library pathlib. (You can also get it for Python 2.6 or 2.7 using pip install pathlib.) The authors wrote: "The aim of this library is to provide a simple hierarchy of classes to handle filesystem paths and the common operations users do over them."

To get an absolute path in Windows:

>>> from pathlib import Path
>>> p = Path("pythonw.exe").resolve()
>>> p
WindowsPath('C:/Python27/pythonw.exe')
>>> str(p)
'C:\\Python27\\pythonw.exe'

Or on UNIX:

>>> from pathlib import Path
>>> p = Path("python3.4").resolve()
>>> p
PosixPath('/opt/python3/bin/python3.4')
>>> str(p)
'/opt/python3/bin/python3.4'

Just a small different from the original solution

Namespaces are actually rather passive in the design of the runtime and serve primarily as organizational tools. The Full Name of a type in .NET consists of the Namespace and Class/Enum/Etc. combined. If you only wish to go through a specific assembly, you would simply loop through the types returned by assembly.GetExportedTypes() checking the value of type.Namespace. If you were trying to go through all assemblies loaded in the current AppDomain it would involve using AppDomain.CurrentDomain.GetAssemblies()

I had the same problem on my site (shameless plug).

I had the nav section "float: right" and the main body of the page has a background image about 250px across aligned to the right and "repeat-y". I then added something with "clear: both" to it. Here is the W3Schools and the CSS clear property.

I placed the clear at the bottom of the "page" classed div. My page source looks something like this.

body
 -> header (big blue banner)
 -> headerNav (green bar at the top)
 -> breadcrumbs (invisible at the moment)
 -> page
     -> navigation (floats to the right)
     -> content (main content)
         -> clear (the quote at the bottom)
         -> footerNav (the green bar at the bottom)
     -> clear (empty but still does something)
 -> footer (blue thing at the bottom)

I hope that helps :)

There is not an equivalent statement for export in Windows Command Prompt. In Windows the environment is copied so when you exit from the session (from a called command prompt or from an executable that set a variable) the variable in Windows get lost. You can set it in user registry or in machine registry via setx but you won't see it if you not start a new command prompt.

If I remember well, some CSS properties you apply to table are not inherited as expected. So you should indeed apply the style directly to td,tr and th elements.

If you need to add styling to each column, use the <col> element in your table.

See an example here: http://jsfiddle.net/GlauberRocha/xkuRA/2/

NB: You can't have a margin in a td. Use padding instead.

You can use like the following

 <android.support.v7.widget.Toolbar
    android:id="@+id/top_actionbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppThemeToolbar">

    <TextView
        android:id="@+id/pageTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        />
</android.support.v7.widget.Toolbar>

For the benefit of others, I though I'd include what I did.

Since you cannot get Visual Studio (2010 in my case) to ignore the LNK4204 warnings, my approach was to give it what it wanted: the pdb files. As I was using open source libraries in my case, I have the code building the pdb files already.

BUT, the default is to name all of the PDF files the same thing: vc100.pdb in my case. As you need a .pdb for each and every .lib, this creates a problem, especially if you are using something like ImageMagik, which creates about 20 static .lib files. You cannot have 20 lib files in one directory (which your application's linker references to link in the libraries from) and have all the 20 .pdb files called the same thing.

My solution was to go and rebuild my static library files, and configure VS2010 to name the .pdb file with respect to the PROJECT. This way, each .lib gets a similarly named .pdb, and you can put all of the LIBs and PDBs in one directory for your project to use.

So for the "Debug" configuraton, I edited:

Properties->Configuration Properties -> C/C++ -> Output Files -> Program Database File Name from

$(IntDir)vc$(PlatformToolsetVersion).pdb

to be the following value:

$(OutDir)vc$(PlatformToolsetVersion)D$(ProjectName).pdb

Now rather than somewhere in the intermediate directory, the .pdb files are written to the output directory, where the .lib files are also being written, AND most importantly, they are named with a suffix of D+project name. This means each library project produduces a project .lib and a project specific .pdb.

I'm now able to copy all of my release .lib files, my debug .lib files and the debug .pdb files into one place on my development system, and the project that uses that 3rd party library in debug mode, has the pdb files it needs in debug mode.

My best guess as to the answer: Consider these 3 options for how to get the CSRF token down from the server to the browser.

1. In the request body (not an HTTP header).
2. In a custom HTTP header, not Set-Cookie.
3. As a cookie, in a Set-Cookie header.

I think the 1st one, request body (while demonstrated by the Express tutorial I linked in the question), is not as portable to a wide variety of situations; not everyone is generating every HTTP response dynamically; where you end up needing to put the token in the generated response might vary widely (in a hidden form input; in a fragment of JS code or a variable accessible by other JS code; maybe even in a URL though that seems generally a bad place to put CSRF tokens). So while workable with some customization, #1 is a hard place to do a one-size-fits-all approach.

The second one, custom header, is attractive but doesn't actually work, because while JS can get the headers for an XHR it invoked, it can't get the headers for the page it loaded from.

That leaves the third one, a cookie carried by a Set-Cookie header, as an approach that is easy to use in all situations (anyone's server will be able to set per-request cookie headers, and it doesn't matter what kind of data is in the request body). So despite its downsides, it was the easiest method for frameworks to implement widely.

I've found that Spring's repeat annotation is useful for that kind of thing:

@Repeat(value = 10)

Latest (Spring Framework 4.3.11.RELEASE API) doc:

• org.springframework.test.annotation
• Unit Testing in Spring

info = [];
info[0] = 'hi';
info[1] = 'hello';


$.ajax({
   type: "POST",
   data: {info:info},
   url: "index.php",
   success: function(msg){
     $('.answer').html(msg);
   }
});

Create your Datafile like this:

# X      Y
10000.0 0.01
100000.0 0.05
1000000.0 0.45

And plot it with

$ gnuplot -p -e "plot 'filename.dat'"

There is a good tutorial: http://www.gnuplotting.org/introduction/plotting-data/

You're probably just getting a stack overflow here. The array is too big to fit in your program's stack address space.

If you allocate the array on the heap you should be fine, assuming your machine has enough memory.

int* array = new int[1000000];

But remember that this will require you to delete[] the array. A better solution would be to use std::vector<int> and resize it to 1000000 elements.

If you are using v2.2.0 then there is one more option available to detect changes in $routes.

To react to params changes in the same component, you can watch the $route object:

const User = {
  template: '...',
  watch: {
    '$route' (to, from) {
      // react to route changes...
    }
  }
}

Or, use the beforeRouteUpdate guard introduced in 2.2:

const User = {
  template: '...',
  beforeRouteUpdate (to, from, next) {
    // react to route changes...
    // don't forget to call next()
  }
}

Reference: https://router.vuejs.org/en/essentials/dynamic-matching.html

Use this instead:

string objTextBox = t.Text;

The object t is the TextBox. The object you call objTextBox is assigned the ID property of the TextBox.

So better code would be:

TextBox objTextBox = (TextBox)sender;
string theText = objTextBox.Text;

You can use the "vh" length unit for the min-height property of the element itself and its parents. It's supported since IE9:

<body class="full-height">
    <form id="form1">
    <div id="header">
        <a title="Home" href="index.html" />
    </div>

    <div id="menuwrapper">
        <div id="menu">
        </div>
    </div>

    <div id="content" class="full-height">
    </div>
</body>

CSS:

.full-height {
    min-height: 100vh;
    box-sizing: border-box;
}

As of the latest Bootstrap (3.1.x), the way to achieve a fluid layout it to use .container-fluid class.

See Bootstrap grid for reference

This is something like the regular expression you need:

([^-]*)-

Quick tests in JavaScript:

/([^-]*)-/.exec('text-1')[1] // 'text'

/([^-]*)-/.exec('foo-bar-1')[1] // 'foo'

/([^-]*)-/.exec('-1')[1] // ''

/([^-]*)-/.exec('quux')[1] // explodes

Versions of @angular/compiler-cli and typescript could not be determined. The most common reason for this is a broken npm install.

Please make sure your package.json contains both @angular/compiler-cli and typescript in devDependencies, then delete node_modules and package-lock.json (if you have one) and run npm install again.

try this package, works wonders, and was made for date/time...

library(lubridate)
Portfolio$Date2 <- mdy(Portfolio.all$Date2)

lines=[]
with open('file') as file:
   lines.append(file.readline())

If you're using Devise, please note that

For Rails 5, protect_from_forgery is no longer prepended to the before_action chain, so if you have set authenticate_user before protect_from_forgery, your request will result in "Can't verify CSRF token authenticity." To resolve this, either change the order in which you call them, or use protect_from_forgery prepend: true.

Documentation

You could use width: 100%; in your css.

INVISIBLE:
The view has to be drawn and it takes time.

GONE:
The view doesn't have to be drawn.

Have you looked at angular-ui bootstrap? There's a Dialog (ui.bootstrap.dialog) directive that works quite well. You can close the dialog during the call back the angular way (per the example):

$scope.close = function(result){
  dialog.close(result);
};

Update:

The directive has since been renamed Modal.

If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json

Json(someDictionaryObj, JsonRequestBehavior.AllowGet);

Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5

as for your web request...it seems ok at first glance..

I would use something like this..

public void WebRequestinJson(string url, string postData)
    {
    StreamWriter requestWriter;

    var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
    if (webRequest != null)
    {
        webRequest.Method = "POST";
        webRequest.ServicePoint.Expect100Continue = false;
        webRequest.Timeout = 20000;

        webRequest.ContentType = "application/json";
        //POST the data.
        using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }
    }
}

May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.

I had the same problem, no possible connection at second login.

After solving the problem (useSecurity, etc., see above), I realized that admin/admin worked (with Synology, it that's relevant).

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape> 

I normally configure the applicationContext using Annotation based configuration rather than XML based configuration. Anyway, I believe both of them have the same priority.

*Answering your question, system variable has higher priority *

Getting profile based beans from applicationContext

• Use @Profile on a Bean

@Component
@Profile("dev")
public class DatasourceConfigForDev

Now, the profile is dev

Note : if the Profile is given as @Profile("!dev") then the profile will exclude dev and be for all others.

• Use profiles attribute in XML

<beans profile="dev">
    <bean id="DatasourceConfigForDev" class="org.skoolguy.profiles.DatasourceConfigForDev"/>
</beans>

Set the value for profile:

• Programmatically via WebApplicationInitializer interface

  In web applications, WebApplicationInitializer can be used to configure the ServletContext programmatically

@Configuration
public class MyWebApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
            servletContext.setInitParameter("spring.profiles.active", "dev");
    }
}

• Programmatically via ConfigurableEnvironment

  You can also set profiles directly on the environment:

    @Autowired
    private ConfigurableEnvironment env;

    // ...

    env.setActiveProfiles("dev");

• Context Parameter in web.xml

  profiles can be activated in the web.xml of the web application as well, using a context parameter:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </context-param>
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>dev</param-value>
    </context-param>

• JVM System Parameter

  The profile names passed as the parameter will be activated during application start-up:

  -Dspring.profiles.active=dev
  

  In IDEs, you can set the environment variables and values to use when an application runs. The following is the Run Configuration in Eclipse:

• Environment Variable

  to set via command line : export spring_profiles_active=dev

Any bean that does not specify a profile belongs to “default” profile.

The priority order is :

1. Context parameter in web.xml
2. WebApplicationInitializer
3. JVM System parameter
4. Environment variable

WHAT "return false" IS REALLY DOING?

return false is actually doing three very separate things when you call it:

1. event.preventDefault();
2. event.stopPropagation();
3. Stops callback execution and returns immediately when called.

See jquery-events-stop-misusing-return-false for more information.

For example :

while clicking this link, return false will cancel the default behaviour of the browser.

<a href='#' onclick='someFunc(3.1415926); return false;'>Click here !</a>

Building on the other answers, I simplified things a bit. By cloning the last element, we get the "add new" button for free (you have to change the ID to a class because of the cloning) and also reduce DOM operations. I had to use filter() instead of find() to get only the last element.

$('.js-addNew').on('click', function(e) {
   e.preventDefault();
   var $rows   = $('.person'),
       $last   = $rows.filter(':last'),
       $newRow = $last.clone().insertAfter($last);

   $last.find($('.js-addNew')).remove(); // remove old button
   $newRow.hide().find('input').val('');
   $newRow.slideDown(500);
});

You could avoid changing the code (although I recommend Boris' answer) and mock the constructor, like in this example for mocking the creation of a File object inside a method. Don't forget to put the class that will create the file in the @PrepareForTest.

 Task.WaitAll(Task.Run(async () => await GetResponse<MyObject>("my url")));

Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.

Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

The below example is the easiest way . I have tested and passed in Protractor Version 5.4.2

//Drop down selection  using option's visibility text 

 element(by.model('currency')).element(by.css("[value='Dollar']")).click();
 Or use this, it   $ isshort form for  .By.css
  element(by.model('currency')).$('[value="Dollar"]').click();

//To select using index

var select = element(by.id('userSelect'));
select.$('[value="1"]').click(); // To select using the index .$ means a shortcut to .By.css

Full code

describe('Protractor Demo App', function() {

  it('should have a title', function() {

     browser.driver.get('http://www.way2automation.com/angularjs-protractor/banking/#/');
    expect(browser.getTitle()).toEqual('Protractor practice website - Banking App');
    element(by.buttonText('Bank Manager Login')).click();
    element(by.buttonText('Open Account')).click();

    //Drop down selection  using option's visibility text 
  element(by.model('currency')).element(by.css("[value='Dollar']")).click();

    //This is a short form. $ in short form for  .By.css
    // element(by.model('currency')).$('[value="Dollar"]').click();

    //To select using index
    var select = element(by.id('userSelect'));
    select.$('[value="1"]').click(); // To select using the index .$ means a shortcut to .By.css
    element(by.buttonText("Process")).click();
    browser.sleep(7500);// wait in miliseconds
    browser.switchTo().alert().accept();

  });
});

Chris Beeley is rigth, you only need the proportions by column. Using your data is:

 your_matrix<-( 
               rbind(
                       c(23,234,324), 
                       c(34,534,12), 
                       c(56,324,124), 
                       c(34,234,124),
                       c(123,534,654)
                    )
                )

 barplot(prop.table(your_matrix, 2) )

Gives:

Just compare the column with that value:

In [9]: df = pandas.DataFrame([1,2,3,4], columns=["data"])

In [10]: df
Out[10]: 
   data
0     1
1     2
2     3
3     4

In [11]: df["desired"] = df["data"] > 2.5
In [11]: df
Out[12]: 
   data desired
0     1   False
1     2   False
2     3    True
3     4    True

optionalUsers.orElseThrow(() -> new UsernameNotFoundException("Username not found"));

This will do the trick!

div {
  height: 100vh;
  width: 100vw;
}

Use config something like this:

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

and then you'll need three files:

• applicationContext.xml;
• myservlet-servlet.xml; and
• user-webservice-servlet.xml.

The *-servlet.xml files are used automatically and each creates an application context for that servlet.

From the Spring documentation, 13.2. The DispatcherServlet:

The framework will, on initialization of a DispatcherServlet, look for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and create the beans defined there (overriding the definitions of any beans defined with the same name in the global scope).

If you are using Python, I would suggest by exploring the request object:

dir(request)

Since the object support the method dict:

request.__dict__

It can be printed or saved. I use it to log 404 codes in Flask:

@app.errorhandler(404)
def not_found(e):
    with open("./404.csv", "a") as f:
        f.write(f'{datetime.datetime.now()},{request.__dict__}\n')
    return send_file('static/images/Darknet-404-Page-Concept.png', mimetype='image/png')

File f = null;
File[] paths;

try {

    f = new File(dir);

    // filefilter
    FilenameFilter fileNameFilter = new FilenameFilter() {

        public boolean accept(File dir, String name) {

            if (name.lastIndexOf('.') > 0) {

                int lastIndex = name.lastIndexOf('.');
                String str = name.substring(lastIndex);

                if (str.equals("." + selectlogtype)) {
                    return true;
                }
            }
            return false;
        }
    };

    paths = f.listFiles(fileNameFilter);

    for (int i = 0; i < paths.length; i++) {
        try {

            FileWriter fileWriter = new FileWriter("C:/Users/maya02/workspace/ftp_log/filefilterlogtxt");
            PrintWriter bWriter = new PrintWriter(fileWriter);

            for (File writerpath1 : paths) {
                bWriter.println(writerpath1);
            }

            bWriter.close();
        } 
        catch (IOException e) { System.out.println("HATA!!"); }
    }
    System.out.println("path dosyaya aktarildi!.");
} 
catch (Exception e) { }

You can get all phone contacts using this:

    Cursor c = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[] { ContactsContract.Contacts._ID,
                    ContactsContract.Contacts.DISPLAY_NAME,
                    ContactsContract.CommonDataKinds.Phone.NUMBER,
                    ContactsContract.RawContacts.ACCOUNT_TYPE },
            ContactsContract.RawContacts.ACCOUNT_TYPE + " <> 'google' ",
            null, null);

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

::========================================================================  
::== CREATE UNIQUE DATETIME STRING IN FORMAT YYYYMMDD-HHMMSS   
::======= ================================================================  
FOR /f %%a IN ('WMIC OS GET LocalDateTime ^| FIND "."') DO SET DTS=%%a  
SET DATETIME=%DTS:~0,8%-%DTS:~8,6%  

The first line always outputs in this format regardles of timezone:
20150515150941.077000+120
This leaves you with just formatting the output to fit your wishes.

You can use SOAP services this way too:

<?php 
//Create the client object
$soapclient = new SoapClient('http://www.webservicex.net/globalweather.asmx?WSDL');

//Use the functions of the client, the params of the function are in 
//the associative array
$params = array('CountryName' => 'Spain', 'CityName' => 'Alicante');
$response = $soapclient->getWeather($params);

var_dump($response);

// Get the Cities By Country
$param = array('CountryName' => 'Spain');
$response = $soapclient->getCitiesByCountry($param);

var_dump($response);

This is an example with a real service, and it works when the url is up.

Just in case the http://www.webservicex.net is down.

Here is another example using the example web service from W3C XML Web Services example, you can find more information on the link.

<?php
//Create the client object
$soapclient = new SoapClient('https://www.w3schools.com/xml/tempconvert.asmx?WSDL');

//Use the functions of the client, the params of the function are in
//the associative array
$params = array('Celsius' => '25');
$response = $soapclient->CelsiusToFahrenheit($params);

var_dump($response);

// Get the Celsius degrees from the Farenheit
$param = array('Fahrenheit' => '25');
$response = $soapclient->FahrenheitToCelsius($param);

var_dump($response);

This is working and returning the converted temperature values.

Hope this helps.

You must add this code in global.aspx:

 protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
                HttpContext.Current.Response.End();
            }
        }

shortest way with lodash/underscore and es6:

_.zip(...matrix)

where matrix could be:

const matrix = [[1,2,3], [1,2,3], [1,2,3]];

I have gone through array of solutions and this is what I found to have worked great for me.

In my case I needed to send a post request with some credentials. Small overhead was to add jquery inside the script. But was worth it.

var printPDF = function () {
        //prevent double sending
        var sendz = {};
        sendz.action = "Print";
        sendz.url = "api/Print";
        jQuery('<form action="' + sendz.url + '" method="POST">' +
            '<input type="hidden" name="action" value="Print" />'+
            '<input type="hidden" name="userID" value="'+$scope.user.userID+'" />'+
            '<input type="hidden" name="ApiKey" value="' + $scope.user.ApiKey+'" />'+
            '</form>').appendTo('body').submit().remove();

    }

Python has several options for HTML scraping in addition to Beatiful Soup. Here are some others:

• mechanize: similar to perl WWW:Mechanize. Gives you a browser like object to ineract with web pages
• lxml: Python binding to libwww. Supports various options to traverse and select elements (e.g. XPath and CSS selection)
• scrapemark: high level library using templates to extract informations from HTML.
• pyquery: allows you to make jQuery like queries on XML documents.
• scrapy: an high level scraping and web crawling framework. It can be used to write spiders, for data mining and for monitoring and automated testing

Use the ll (el-el) long-long modifier with the u (unsigned) conversion. (Works in windows, GNU).

printf("%llu", 285212672);

It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:

var canvas = document.createElement('canvas');
canvas.id     = "CursorLayer";
canvas.width  = 1224;
canvas.height = 768;
canvas.style.zIndex   = 8;
canvas.style.position = "absolute";
canvas.style.border   = "1px solid";
window.onload = function() {
    document.getElementById("CursorLayer");
}

• sessionStorage maintains a separate storage area for each given origin that's available for the duration of the page session (as long as the browser is open, including page reloads and restores)

• localStorage does the same thing, but persists even when the browser is closed and reopened.

I took this from Web Storage API

 ymin, ymax = axes.get_ylim()

If you are using the plt api directly, you can avoid calls to axes altogether:

def myplotfunction(title, values, errors, plot_file_name):

    # plot errorbars
    indices = range(0, len(values))
    fig = plt.figure()
    plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')

    plt.ylim([-0.5, len(values) - 0.5])
    plt.xlabel('My x-axis title')
    plt.ylabel('My y-axis title')

    # title
    plt.title(title)

    # save as file
    plt.savefig(plot_file_name)

   # close figure
    plt.close(fig)

Try this:

<div
  class="modal fade"
  id="customer_bill_gen"
  data-keyboard="false"
  data-backdrop="static"
>

      beforeShow: function(el) {
            if ( el.getAttribute("readonly") !== null ) {
                if ( (el.value == null) || (el.value == '') ) {
                    $(el).datepicker( "option", "minDate", +1 );
                    $(el).datepicker( "option", "maxDate", -1 );
                } else {
                    $(el).datepicker( "option", "minDate", el.value );
                    $(el).datepicker( "option", "maxDate", el.value );
                }
            }
        },

You can use the backtick operator:

& "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" `
    -verb:sync `
    -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" `
    -dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"

That's still a little too long for my taste, so I'd use some well-named variables:

$msdeployPath = "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe"
$verbArg = '-verb:sync'
$sourceArg = '-source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web"'
$destArg = '-dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"'

& $msdeployPath $verbArg $sourceArg $destArg

In my case(Bootstrap) the issue was, having the JQuery 3.0.0 which is also not fine, So using a version which is an earlier version like 2.2.4.

The Error i got was: Bootstrap's JavaScript requires jQuery version 1.9.1 or higher, but lower than version 3

Using any of these CDN below as the source would help if this is the case!

jQuery version 2.2.4:

http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.2.4.js

http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.2.4.min.js

Hope this helped at least someone!.. :)

Thank you!

Use JQuery. You need to set-up a click event on your button which will toggle the visibility of your wizard div.

$('#btn').click(function() {
    $('#wizard').toggle();
});

Refer to the JQuery website for more information.

This can also be done without JQuery. Using only standard JavaScript:

<script type="text/javascript">
   function toggle_visibility(id) {
       var e = document.getElementById(id);
       if(e.style.display == 'block')
          e.style.display = 'none';
       else
          e.style.display = 'block';
   }
</script>

Then add onclick="toggle_visibility('id_of_element_to_toggle');" to the button that is used to show and hide the div.

Python lacks the tail recursion optimizations common in functional languages like lisp. In Python, recursion is limited to 999 calls (see sys.getrecursionlimit).

If 999 depth is more than you are expecting, check if the implementation lacks a condition that stops recursion, or if this test may be wrong for some cases.

I dare to say that in Python, pure recursive algorithm implementations are not correct/safe. A fib() implementation limited to 999 is not really correct. It is always possible to convert recursive into iterative, and doing so is trivial.

It is not reached often because in many recursive algorithms the depth tend to be logarithmic. If it is not the case with your algorithm and you expect recursion deeper than 999 calls you have two options:

1) You can change the recursion limit with sys.setrecursionlimit(n) until the maximum allowed for your platform:

sys.setrecursionlimit(limit):

Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python.

The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a crash.

2) You can try to convert the algorithm from recursive to iterative. If recursion depth is bigger than allowed by your platform, it is the only way to fix the problem. There are step by step instructions on the Internet and it should be a straightforward operation for someone with some CS education. If you are having trouble with that, post a new question so we can help.

Thanks to jimhark's answer and other answers here, I found a way to do it in PowerShell:

$ProcessID = 1234
$MemberDefinition = '
    [DllImport("kernel32.dll")]public static extern bool FreeConsole();
    [DllImport("kernel32.dll")]public static extern bool AttachConsole(uint p);
    [DllImport("kernel32.dll")]public static extern bool GenerateConsoleCtrlEvent(uint e, uint p);
    public static void SendCtrlC(uint p) {
        FreeConsole();
        if (AttachConsole(p)) {
            GenerateConsoleCtrlEvent(0, p);
            FreeConsole();
        }
        AttachConsole(uint.MaxValue);
    }'
Add-Type -Name 'dummyName' -Namespace 'dummyNamespace' -MemberDefinition $MemberDefinition
[dummyNamespace.dummyName]::SendCtrlC($ProcessID) }

What made things work was sending the GenerateConsoleCtrlEvent to the desired process group instead of all processes that share the console of the calling process and AttachConsole back to the console of the parent of the current process.

Make the class serializable by implementing the interface java.io.Serializable.

• java.io.Serializable - Marker Interface which does not have any methods in it.
• Purpose of Marker Interface - to tell the ObjectOutputStream that this object is a serializable object.

With angular cli

npm install angular-material-icons --save

or

npm install material-design-icons-iconfont --save

material-design-icons-iconfont is the latest updated version of the icons. angular-material-icons is not updated for a long time

Wait wait wait install to be done and then add it to angular.json -> projects -> architect -> styles

 "styles": [
          "node_modules/material-design-icons/iconfont/material-icons.css",
          "src/styles.scss"
        ],

or if you installed material-desing-icons-iconfont then

"styles": [

FOR SQLALCHEMY AND PYTHON

The encoding used for Unicode has traditionally been 'utf8'. However, for MySQL versions 5.5.3 on forward, a new MySQL-specific encoding 'utf8mb4' has been introduced, and as of MySQL 8.0 a warning is emitted by the server if plain utf8 is specified within any server-side directives, replaced with utf8mb3. The rationale for this new encoding is due to the fact that MySQL’s legacy utf-8 encoding only supports codepoints up to three bytes instead of four. Therefore, when communicating with a MySQL database that includes codepoints more than three bytes in size, this new charset is preferred, if supported by both the database as well as the client DBAPI, as in:

e = create_engine(
    "mysql+pymysql://scott:tiger@localhost/test?charset=utf8mb4")
All modern DBAPIs should support the utf8mb4 charset.

For me i followed the above answer and modified it a bit:

1. Just grab your ipv4 address using ipconfig on command prompt
2. Go to the file in which flask code is present
3. In main function write app.run(host= 'your ipv4 address')

Eg:

Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.

Note that the accepted answer:

• iterates over the whole data, regardless of whether a nan is found
• creates a temporary array of size N, which is redundant.

A better solution is to return True immediately when NAN is found:

import numba
import numpy as np

NAN = float("nan")

@numba.njit(nogil=True)
def _any_nans(a):
    for x in a:
        if np.isnan(x): return True
    return False

@numba.jit
def any_nans(a):
    if not a.dtype.kind=='f': return False
    return _any_nans(a.flat)

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 573us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 774ns  (!nanoseconds)

and works for n-dimensions:

array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd)  # 774ns

Compare this to the numpy native solution:

def any_nans(a):
    if not a.dtype.kind=='f': return False
    return np.isnan(a).any()

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 456us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 470us

%timeit np.isnan(array1M).any()  # 532us

The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.

If you are using management studio and have the query analyzer window open you can drag the table name to the query analyzer window and ... bingo! you get the table script. I've not tried this in SQL2008

There are two ways-

whoami

or

echo $USER

The command start [filename] opened the file in my default text editor.

This command also worked for opening a non-.txt file.

The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type.

• Enum.valueOf class
  (The special implicit values method is mentioned in description of valueOf method)

All the constants of an enum type can be obtained by calling the implicit public static T[] values() method of that type.

• Enum Types, Section 8.9, Java Language Specification

The values function simply list all values of the enumeration.

You Can use just finish(); everywhere after Activity Start for clear that Activity from Stack.

dbms_output.put_line('Hi,');
dbms_output.put_line('good');
dbms_output.put_line('morning');
dbms_output.put_line('friends');

or

DBMS_OUTPUT.PUT_LINE('Hi, ' || CHR(13) || CHR(10) || 
                     'good' || CHR(13) || CHR(10) ||
                     'morning' || CHR(13) || CHR(10) ||
                     'friends' || CHR(13) || CHR(10) ||);

try it.

One of the values you pass on to Ancestors becomes None at some point, it says, so check if otu, tree, tree[otu] or tree[otu][0] are None in the beginning of the function instead of only checking tree[otu][0][0] == None. But perhaps you should reconsider your path of action and the datatype in question to see if you could improve the structure somewhat.

This is what I did in my application

NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];

Hopefully this simple answer will help somebody...

Note that is may also be desired to stabilize the sort with the -s switch, so that equally ranked lines maintain their original relative order in the output too.

You could use the same mechanism the XAML reading system uses: Type converters

var converter = new System.Windows.Media.BrushConverter();
var brush = (Brush)converter.ConvertFromString("#FFFFFF90");
Fill = brush;

try this.

<Route exact path="/details/:id" render={(props)=>{return(
    <DetailsPage id={props.match.params.id}/>)
}} />

In details page try this...

this.props.id

Not the answer for this question

I got this exception when trying to delete a folder where i deleted the file inside.

Example:

createFolder("folder");  
createFile("folder/file");  
deleteFile("folder/file");  
deleteFolder("folder"); // error here

While deleteFile("folder/file"); returned that it was deleted, the folder will only be considered empty after the program restart.

On some operating systems it may not be possible to remove a file when it is open and in use by this Java virtual machine or other programs.

For some reason, every single post asking about newline escapes in PHP fails to mention the case that simply inserting a newline into single-quoted strings will do exactly what you think:

ex 1.

 echo 'foo\nbar';

Example 1 clearly does not print the desired result, however, while it is true you cannot escape a newline in single-quotes, you can have one:

ex 2.

 echo 'foo
 bar';

Example 2 has exactly the desired behavior. Unfortunately the newline that is inserted is operating system dependent. This usually isn't a problem, as web browsers/servers will correctly interpret the newline whether it is \r, \r\n, or \n.

Obviously this solution is not ideal if you plan to distribute the file through other means then a web browser and to multiple operating systems. In that case you should see one of the other answers.

note: using a feature rich text editor you should be able to insert a newline as a binary character(s) that represents a newline on a different operating system than the one editing the file. If all else fails, simply using a hex editor to insert the binary ascii character would do.

You can make a template of templates too, and reach private variable.

var a= {e:10, gy:'sfdsad'}; //global object

console.log(`e is ${a.e} and gy is ${a.gy}`); 
//e is 10 and gy is sfdsad

var b = "e is ${a.e} and gy is ${a.gy}" // template string
console.log( `${b}` );
//e is ${a.e} and gy is ${a.gy}

console.log( eval(`\`${b}\``) ); // convert template string to template
//e is 10 and gy is sfdsad

backtick( b );   // use fonction's variable
//e is 20 and gy is fghj

function backtick( temp ) {
  var a= {e:20, gy:'fghj'}; // local object
  console.log( eval(`\`${temp}\``) );
}

Clear backstack without loops

String name = getSupportFragmentManager().getBackStackEntryAt(0).getName();
getSupportFragmentManager().popBackStack(name, FragmentManager.POP_BACK_STACK_INCLUSIVE);

Where name is the addToBackStack() parameter

getSupportFragmentManager().beginTransaction().
                .replace(R.id.container, fragments.get(titleCode))
                .addToBackStack(name)

I encountered this issue when installing a different package, and it could be caused by the GOROOT and GOPATH configuration on your PATH. I tend not to set GOROOT because my OS X installation handled it (I believe) for me.

1. Ensure the following in your .profile (or wherever you store profile configuration: .bash_profile, .zshrc, .bashrc, etc):

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOROOT/bin
   

2. Also, you likely want to unset GOROOT, as well, in case that path is also incorrect.

3. Furthermore, be sure to clean your PATH, similarly to what I've done below, just before the GOPATH assignment, i.e.:

   export PATH=$HOME/bin:/usr/local/bin:$PATH
   export GOPATH=$HOME/go
   export PATH=$PATH:$GOROOT/bin
   

4. Then, source <.profile> to activate

5. retry go get

I also like to build locators from up to bottom like:

//div[contains(@class,'btn-group')][./button[contains(.,'Arcade Reader')]]/button[@name='settings']

It's pretty simple, as we just search btn-group with button[contains(.,'Arcade Reader')] and get it's button[@name='settings']

That's just another option to build xPath locators

What is the profit of searching wrapper element: you can return it by method (example in java) and just build selenium constructions like:

getGroupByName("Arcade Reader").find("button[name='settings']");
getGroupByName("Arcade Reader").find("button[name='delete']");

or even simplify more

getGroupButton("Arcade Reader", "delete").click();

Interesting observation: Tried to copy the same file via various java classes and printed time in nano seconds.

Duration using FileOutputStream byte stream: 4 965 078

Duration using BufferedOutputStream: 1 237 206

Duration using (character text Reader: 2 858 875

Duration using BufferedReader(Buffered character text stream: 1 998 005

Duration using (Files NIO copy): 18 351 115

when using Files Nio copy option it took almost 18 times longer!!! Nio is the slowest option to copy files and BufferedOutputStream looks like the fastest. I used the same simple text file for each class.

I made a simpler way to set a min/max to an Edittext. I use arithmetic keypad and I work with this method:

 private int limit(EditText x,int z,int limin,int limax){

    if( x.getText().toString()==null || x.getText().toString().length()==0){
        x.setText(Integer.toString(limin));
        return z=0;
    }
    else{
        z = Integer.parseInt(x.getText().toString());
         if(z <limin || z>limax){
             if(z<10){
                 x.setText(Integer.toString(limin));
                return  z=0;
             }
            else{
                x.setText(Integer.toString(limax));
                return z=limax;
            }

         }
         else
            return z = Integer.parseInt(x.getText().toString());
    }
 }

The method accepts all of your values but if a value of users in not adhere to your limits it will be set automatically to the min/max limit. For ex. limit limin=10, limax =80 if the user sets 8, automatically 10 is saved to a variable and EditText is set to 10.

The following gives pixel-perfect consistency across browsers, even IE9:

The approach is quite sensible, to the point of being obvious:

1. Create an input and a label.
2. Display them as block, so you can float them as you like.
3. Set the height and the line-height to the same value to ensure they center and align vertically.
4. For em measurements, to calculate the height of the elements, the browser must know the height of the font for those elements, and it must not itself be set in em measurements.

This results in a globally applicable general rule:

input, label {display:block;float:left;height:1em;line-height:1em;}

With font size adaptable per form, fieldset or element.

#myform input, #myform label {font-size:20px;}

Tested in latest Chrome, Safari, and Firefox on Mac, Windows, Iphone, and Android. And IE9.

This method is likely applicable to all input types that are not higher than one line of text. Apply a type rule to suit.

epoch

A full training pass over the entire dataset such that each example has been seen once. Thus, an epoch represents N/batch size training iterations, where N is the total number of examples.

iteration

A single update of a model's weights during training. An iteration consists of computing the gradients of the parameters with respect to the loss on a single batch of data.

as bonus:

batch

The set of examples used in one iteration (that is, one gradient update) of model training.

See also batch size.

Go to the website nodejs.org and download the latest pkg then install. it works for me

I used brew to upgrade my node. It has installed but it located in /usr/local/Cellar/node/5.5.0 and there is a default node in /usr/local/bin/node which bothers me. I don't want to make soft link because I don't really know how brew is organized. So I download the pkg file, installed and I got this info:

Node.js was installed at

/usr/local/bin/node

npm was installed at

/usr/local/bin/npm

Make sure that /usr/local/bin is in your $PATH.

Now the upgrade is completed

Reviewing the Apple Developer documentation I found the CFUUID object is available on the iPhone OS 2.0 and later.

A sorting algorithm is said to be stable if two objects with equal keys appear in the same order in sorted output as they appear in the input array to be sorted. Some sorting algorithms are stable by nature like Insertion sort, Merge Sort, Bubble Sort, etc. And some sorting algorithms are not, like Heap Sort, Quick Sort, etc.

Background: a "stable" sorting algorithm keeps the items with the same sorting key in order. Suppose we have a list of 5-letter words:

peach
straw
apple
spork

If we sort the list by just the first letter of each word then a stable-sort would produce:

apple
peach
straw
spork

In an unstable sort algorithm, straw or spork may be interchanged, but in a stable one, they stay in the same relative positions (that is, since straw appears before spork in the input, it also appears before spork in the output).

We could sort the list of words using this algorithm: stable sorting by column 5, then 4, then 3, then 2, then 1. In the end, it will be correctly sorted. Convince yourself of that. (by the way, that algorithm is called radix sort)

Now to answer your question, suppose we have a list of first and last names. We are asked to sort "by last name, then by first". We could first sort (stable or unstable) by the first name, then stable sort by the last name. After these sorts, the list is primarily sorted by the last name. However, where last names are the same, the first names are sorted.

You can't stack unstable sorts in the same fashion.

Use Guzzle. It's a "PHP HTTP client that makes it easy to work with HTTP/1.1 and takes the pain out of consuming web services". Working with Guzzle is much easier than working with cURL.

Here's an example from the Web site:

$client = new GuzzleHttp\Client();
$res = $client->get('https://api.github.com/user', [
    'auth' =>  ['user', 'pass']
]);
echo $res->getStatusCode();           // 200
echo $res->getHeader('content-type'); // 'application/json; charset=utf8'
echo $res->getBody();                 // {"type":"User"...'
var_export($res->json());             // Outputs the JSON decoded data

If one assumes he really needs regexp - which is perfectly reasonable in many contexts - the problem is that the specific regexp variety needs to be specified. For example:

egrep '^(100|[1-9]|[1-9][0-9])$'
grep -E '^(100|[1-9]|[1-9][0-9])$'

work fine if the (...|...) alternative syntax is available. In other contexts, they'd be backslashed like \(...\|...\)

You need to implement RefreshTokenProvider. First create class for RefreshTokenProvider ie.

public class ApplicationRefreshTokenProvider : AuthenticationTokenProvider
{
    public override void Create(AuthenticationTokenCreateContext context)
    {
        // Expiration time in seconds
        int expire = 5*60;
        context.Ticket.Properties.ExpiresUtc = new DateTimeOffset(DateTime.Now.AddSeconds(expire));
        context.SetToken(context.SerializeTicket());
    }

    public override void Receive(AuthenticationTokenReceiveContext context)
    {
        context.DeserializeTicket(context.Token);
    }
}

Then add instance to OAuthOptions.

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/authenticate"),
    Provider = new ApplicationOAuthProvider(),
    AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(expire),
    RefreshTokenProvider = new ApplicationRefreshTokenProvider()
};

public class MyToolbar extends android.support.v7.widget.Toolbar {

public MyToolbar(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
}

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    super.onLayout(changed, l, t, r, b);
    AppCompatTextView textView = (AppCompatTextView) getChildAt(0);
    if (textView!=null) textView.setTextAppearance(getContext(), R.style.TitleStyle);
}

}

Or simple use from MainActivity:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarMain);
setSupportActionBar(toolbar);
((AppCompatTextView) toolbar.getChildAt(0)).setTextAppearance(this, R.style.TitleStyle);

style.xml

<style name="TileStyle" parent="TextAppearance.AppCompat">
    <item name="android:textColor">@color/White</item>
    <item name="android:shadowColor">@color/Black</item>
    <item name="android:shadowDx">-1</item>
    <item name="android:shadowDy">1</item>
    <item name="android:shadowRadius">1</item>
</style>

Having a database table without Primary Key is really and will say extremely BAD PRACTICE...so after you add one (ALTER TABLE)

Run this until you don't see any more duplicated records (that is the purpose of HAVING COUNT)

DELETE FROM [TABLE_NAME] WHERE [Id] IN 
(
    SELECT MAX([Id])
    FROM [TABLE_NAME]
    GROUP BY [TARGET_COLUMN]
    HAVING COUNT(*) > 1
)


SELECT MAX([Id]),[TABLE_NAME], COUNT(*) AS dupeCount
FROM [TABLE_NAME]
GROUP BY [TABLE_NAME]
HAVING COUNT(*) > 1

MAX([Id]) will cause to delete latest records (ones added after first created) in case you want the opposite meaning that in case of requiring deleting first records and leave the last record inserted please use MIN([Id])

Fundamentally, Turing-completeness is one concise requirement, unbounded recursion.

Not even bounded by memory.

I thought of this independently, but here is some discussion of the assertion. My definition of LSP provides more context.

The other answers here don't directly define the fundamental essence of Turing-completeness.

Each deployed webapp has a context.xml file that lives in

$CATALINA_BASE/conf/[enginename]/[hostname]

(conf/Catalina/localhost by default)

and has the same name as the webapp (manager.xml in this case). If no file is present, default values are used.

So, you need to create a file conf/Catalina/localhost/manager.xml and specify the rule you want to allow remote access. For example, the following content of manager.xml will allow access from all machines:

<Context privileged="true" antiResourceLocking="false" 
         docBase="${catalina.home}/webapps/manager">
    <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^YOUR.IP.ADDRESS.HERE$" />
</Context>

Note that the allow attribute of the Valve element is a regular expression that matches the IP address of the connecting host. So substitute your IP address for YOUR.IP.ADDRESS.HERE (or some other useful expression).

Other Valve classes cater for other rules (e.g. RemoteHostValve for matching host names). Earlier versions of Tomcat use a valve class org.apache.catalina.valves.RemoteIpValve for IP address matching.

Once the changes above have been made, you should be presented with an authentication dialog when accessing the manager URL. If you enter the details you have supplied in tomcat-users.xml you should have access to the Manager.

Also, in some cases is important to check the target folder permissions. To give write permission for the user might be the solution. That worked for me.

We can also do this using randint.

from random import randint
l= ['a','b','c']

def get_rand_element(l):
    if l:
        return l[randint(0,len(l)-1)]
    else:
        return None

get_rand_element(l)

I use the following:

Function GetProgramOutput([string]$exe, [string]$arguments)
{
    $process = New-Object -TypeName System.Diagnostics.Process
    $process.StartInfo.FileName = $exe
    $process.StartInfo.Arguments = $arguments
    
    $process.StartInfo.UseShellExecute = $false
    $process.StartInfo.RedirectStandardOutput = $true
    $process.StartInfo.RedirectStandardError = $true
    $process.Start()
    
    $output = $process.StandardOutput.ReadToEnd()   
    $err = $process.StandardError.ReadToEnd()
    
    $process.WaitForExit()
    
    $output
    $err
}
    
$exe = "C:\Program Files\7-Zip\7z.exe"
$arguments = "i"
    
$runResult = (GetProgramOutput $exe $arguments)
$stdout = $runResult[-2]
$stderr = $runResult[-1]
    
[System.Console]::WriteLine("Standard out: " + $stdout)
[System.Console]::WriteLine("Standard error: " + $stderr)

If you want to assert that the two lists are identical, don't complicate things with Hamcrest:

assertEquals(expectedList, actual.getList());

If you really intend to perform an order-insensitive comparison, you can call the containsInAnyOrder varargs method and provide values directly:

assertThat(actual.getList(), containsInAnyOrder("item1", "item2"));

(Assuming that your list is of String, rather than Agent, for this example.)

If you really want to call that same method with the contents of a List:

assertThat(actual.getList(), containsInAnyOrder(expectedList.toArray(new String[expectedList.size()]));

Without this, you're calling the method with a single argument and creating a Matcher that expects to match an Iterable where each element is a List. This can't be used to match a List.

That is, you can't match a List<Agent> with a Matcher<Iterable<List<Agent>>, which is what your code is attempting.

Try pyautogui:

import pyautogui
resolution = pyautogui.size()
print(resolution) 

See parallel. Its syntax is similar to xargs, but it runs the commands in parallel.

I have a simpler vanilla js only solution:

For checkboxes:

document.getElementById("id").oninvalid = function () {
    this.setCustomValidity(this.checked ? '' : 'My message');
};

For inputs:

document.getElementById("id").oninvalid = function () {
    this.setCustomValidity(this.value ? '' : 'My message');
};

Enclose your code with the html and body tags. Size attribute does not correspond to font-size and it looks like its domain does not go beyond value 7. Furthermore font tag is not supported in HTML5. Consider this code for your case

<!DOCTYPE html>
<html>
<body>

<font size="2" face="Courier New" >
<table width="100%">
    <tr>
        <td><b>Client</b></td>
        <td><b>InstanceName</b></td>
        <td><b>dbname</b></td>
        <td><b>Filename</b></td>
        <td><b>KeyName</b></td>
        <td><b>Rotation</b></td>

You can also use scrollOffset in Route.ts. Ref. Router ExtraOptions

@NgModule({
  imports: [
    SomeModule.forRoot(
      SomeRouting,
      {
        scrollPositionRestoration: 'enabled',
        scrollOffset:[0,0]
      })],
  exports: [RouterModule]
})

In both: Anaconda prompt and the old cmd.exe, you change your directory by first changing to the drive you want, by simply writing its name followed by a ':', exe: F: , which will take you to the drive named 'F' on your machine. Then using the command cd to navigate your way inside that drive as you normally would.

All you have to do is apply the format you want in the html helper call, ie.

@Html.TextBoxFor(m => m.RegistrationDate, "{0:dd/MM/yyyy}")

You don't need to provide the date format in the model class.

I use blueimp-md5 which is "Compatible with server-side environments like Node.js, module loaders like RequireJS, Browserify or webpack and all web browsers."

Use it like this:

var md5 = require("blueimp-md5");

var myHashedString = createHash('GreensterRox');

createHash(myString){
    return md5(myString);
}

If passing hashed values around in the open it's always a good idea to salt them so that it is harder for people to recreate them:

createHash(myString){
    var salt = 'HnasBzbxH9';
    return md5(myString+salt);
}

        Pattern p = Pattern.compile(pattern);
        Matcher m =  p.matcher(s);
        while(m.find())
        {
            System.out.println(m.group(2));
            count++;
        }

You can also move mounted out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.

function init() {
  // Use `this` normally
}

new Vue({
  methods:{
    init
  },
  mounted(){
    init.call(this)
  }
})

You are passing hello() as a string, also hello() means execute hello immediately.

try

onClick={hello}

I think placing text inbetween the tags is reserved for browsers that cant handle iframes i.e...

<iframe src ="html_intro.asp" width="100%" height="300">
  <p>Your browser does not support iframes.</p>
</iframe>

You use the 'src' attribute to set the source of the iframes html...

Hope that helps :)

you must enter as administrator right click to microsofft sql server management studio and run as admin

use fwrite() instead of file_put_contents()

Just write what you really wanted to know:

fac.GetCachedValue("Auto Print Clinical Warnings").ToLower().StartsWith("y")

It's much simpler than anything with substring.

I run into same problem.

What I found from documentation, we should use namedspace.

in your case {% url login:login_view %}

#include <termios.h>
#include <stdio.h>

static struct termios old, current;

/* Initialize new terminal i/o settings */
void initTermios(int echo) 
{
  tcgetattr(0, &old); /* grab old terminal i/o settings */
  current = old; /* make new settings same as old settings */
  current.c_lflag &= ~ICANON; /* disable buffered i/o */
  if (echo) {
      current.c_lflag |= ECHO; /* set echo mode */
  } else {
      current.c_lflag &= ~ECHO; /* set no echo mode */
  }
  tcsetattr(0, TCSANOW, &current); /* use these new terminal i/o settings now */
}

/* Restore old terminal i/o settings */
void resetTermios(void) 
{
  tcsetattr(0, TCSANOW, &old);
}

/* Read 1 character - echo defines echo mode */
char getch_(int echo) 
{
  char ch;
  initTermios(echo);
  ch = getchar();
  resetTermios();
  return ch;
}

/* Read 1 character without echo */
char getch(void) 
{
  return getch_(0);
}

/* Read 1 character with echo */
char getche(void) 
{
  return getch_(1);
}

/* Let's test it out */
int main(void) {
  char c;
  printf("(getche example) please type a letter: ");
  c = getche();
  printf("\nYou typed: %c\n", c);
  printf("(getch example) please type a letter...");
  c = getch();
  printf("\nYou typed: %c\n", c);
  return 0;
}

Output:

(getche example) please type a letter: g
You typed: g
(getch example) please type a letter...
You typed: g

This is a very old question, but I found a new solution, so I wrote about it.

First of all, is this way of solution possible while using AutoGenerateColumns?

Yes, that can be done with AttachedProperty as follows.

<DataGrid AutoGenerateColumns="True" 
   local:DataGridOperation.DateTimeFormatAutoGenerate="yy-MM-dd"
   ItemsSource="{Binding}" />

AttachedProperty

There are two AttachedProperty defined that allow you to specify two formats. DateTimeFormatAutoGenerate for DateTime and TimeSpanFormatAutoGenerate for TimeSpan.

class DataGridOperation
{
    public static string GetDateTimeFormatAutoGenerate(DependencyObject obj) => (string)obj.GetValue(DateTimeFormatAutoGenerateProperty);
    public static void SetDateTimeFormatAutoGenerate(DependencyObject obj, string value) => obj.SetValue(DateTimeFormatAutoGenerateProperty, value);
    public static readonly DependencyProperty DateTimeFormatAutoGenerateProperty =
        DependencyProperty.RegisterAttached("DateTimeFormatAutoGenerate", typeof(string), typeof(DataGridOperation),
            new PropertyMetadata(null, (d, e) => AddEventHandlerOnGenerating<DateTime>(d, e)));

    public static string GetTimeSpanFormatAutoGenerate(DependencyObject obj) => (string)obj.GetValue(TimeSpanFormatAutoGenerateProperty);
    public static void SetTimeSpanFormatAutoGenerate(DependencyObject obj, string value) => obj.SetValue(TimeSpanFormatAutoGenerateProperty, value);
    public static readonly DependencyProperty TimeSpanFormatAutoGenerateProperty =
        DependencyProperty.RegisterAttached("TimeSpanFormatAutoGenerate", typeof(string), typeof(DataGridOperation),
            new PropertyMetadata(null, (d, e) => AddEventHandlerOnGenerating<TimeSpan>(d, e)));

    private static void AddEventHandlerOnGenerating<T>(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (!(d is DataGrid dGrid))
            return;

        if ((e.NewValue is string format))
            dGrid.AutoGeneratingColumn += (o, e) => AddFormat_OnGenerating<T>(e, format);
    }

    private static void AddFormat_OnGenerating<T>(DataGridAutoGeneratingColumnEventArgs e, string format)
    {
        if (e.PropertyType == typeof(T))
            (e.Column as DataGridTextColumn).Binding.StringFormat = format;
    }
}

How to use

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

This happens when you specify the incorrect position for the notifyItemChanged , notifyItemRangeInserted etc.For me :

Before : (Erroneous)

public void addData(List<ChannelItem> list) {
  int initialSize = list.size();
  mChannelItemList.addAll(list);
  notifyItemRangeChanged(initialSize - 1, mChannelItemList.size());
 } 

After : (Correct)

 public void addData(List<ChannelItem> list) {
  int initialSize = mChannelItemList.size();
  mChannelItemList.addAll(list);
  notifyItemRangeInserted(initialSize, mChannelItemList.size()-1); //Correct position 
 }

You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

\begin{table}
\begin{tabular}{| p{5cm} | p{5cm} | p{5cm} |}
  -- cut --
\end{tabular}
\caption{My table}
\label{table:kysymys}
\end{table}

Table \ref{table:kysymys} on page \pageref{table:kysymys} refers to the ...

I would do it this way

 $("#idElement").val('optionValue').trigger('change');

For iPhone 5,

@media screen and (device-aspect-ratio: 40/71)

for iPhone 6,7,8

@media only screen and (min-device-width: 375px) and (max-device-width: 667px) and (orientation : portrait)

for iPhone 6+,7+,8+

@media screen and (-webkit-device-pixel-ratio: 3) and (min-device-width: 414px)

Working fine for me as of now.

I solved this question with solution below

  import org.joda.time.LocalDate;
  Date myDate = new Date();
  LocalDate localDate = LocalDate.fromDateFields(myDate);
  System.out.println("My date using Date" Nov 18 11:23:33 BRST 2016);
  System.out.println("My date using joda.time LocalTime" 2016-11-18);

In this case localDate print your date in this format "yyyy-MM-dd"

Since your array elements are arrays themselves with string keys, your best bet is to define a custom comparison function. It's pretty quick and easy to do. Try this:

function invenDescSort($item1,$item2)
{
    if ($item1['price'] == $item2['price']) return 0;
    return ($item1['price'] < $item2['price']) ? 1 : -1;
}
usort($inventory,'invenDescSort');
print_r($inventory);

Produces the following:

Array
(
    [0] => Array
        (
            [type] => pork
            [price] => 5.43
        )

    [1] => Array
        (
            [type] => fruit
            [price] => 3.5
        )

    [2] => Array
        (
            [type] => milk
            [price] => 2.9
        )

)

I was having huge issues with Error 1050 and 150.

The problem, for me was that I was trying to add a constraint with ON DELETE SET NULL as one of the conditions.

Changing to ON DELETE NO ACTION allowed me to add the required FK constraints.

Unfortunately the MySql error messages are utterly unhelpful so I had to find this solution iteratively and with the help of the answers to the question above.

You could also use alias_attribute if you still want to be able to refer to them as tasks as well:

class User < ActiveRecord::Base
  alias_attribute :jobs, :tasks

  has_many :tasks
end

The real problem: How to get the difference of two sets?

The fastest way I've found is to convert the sets to dictionaries first, then diff 'em. Here's a generic approach:

static IEnumerable<T> DictionaryDiff<K, T>(Dictionary<K, T> d1, Dictionary<K, T> d2)
{
    return from x in d1 where !d2.ContainsKey(x.Key) select x.Value;
}

Then you can do something like this:

static public IEnumerable<PropertyInfo> PropertyDiff(Type t1, Type t2)
{
    var d1 = t1.GetProperties().ToDictionary(x => x.Name);
    var d2 = t2.GetProperties().ToDictionary(x => x.Name);
    return DictionaryDiff(d1, d2);
}

Use sum() in place of count()

Try below:

SELECT
    ccc_news . * , 
    SUM(if(ccc_news_comments.id = 'approved', 1, 0)) AS comments
FROM
    ccc_news
    LEFT JOIN
        ccc_news_comments
    ON
        ccc_news_comments.news_id = ccc_news.news_id
WHERE
    `ccc_news`.`category` = 'news_layer2'
    AND `ccc_news`.`status` = 'Active'
GROUP BY
    ccc_news.news_id
ORDER BY
    ccc_news.set_order ASC
LIMIT 20 

Answering late since I recently had the same question when reading text from file; tried several options such as:

with open('verdict.txt') as f: 

First option below produces a list called alist, with '\n' stripped, then joins back into full text (optional if you wish to have only one text):

alist = f.read().splitlines()
jalist = " ".join(alist)

Second option below is much easier and simple produces string of text called atext replacing '\n' with space;

atext = f.read().replace('\n',' ')

It works; I have done it. This is clean, easier, and efficient.

If you really need it, consider redirections.

For example, on request to assets.my-domain.example.com/path/to/file you could perform a 301 or 302 redirection to my-bucket-name.s3.amazonaws.com/path/to/file or s3.amazonaws.com/my-bucket-name/path/to/file (please remember that in the first case my-bucket-name cannot contain any dots, otherwise it won't match *.s3.amazonaws.com, s3.amazonaws.com stated in S3 certificate).

Not tested, but I believe it would work. I see few gotchas, however.

The first one is pretty obvious, an additional request to get this redirection. And I doubt you could use redirection server provided by your domain name registrar — you'd have to upload proper certificate there somehow — so you have to use your own server for this.

The second one is that you can have urls with your domain name in page source code, but when for example user opens the pic in separate tab, then address bar will display the target url.

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

This solution works in all major browsers:

saveSelection() is attached to the onmouseup and onkeyup events of the div and saves the selection to the variable savedRange.

restoreSelection() is attached to the onfocus event of the div and reselects the selection saved in savedRange.

This works perfectly unless you want the selection to be restored when the user clicks the div aswell (which is a bit unintuitative as normally you expect the cursor to go where you click but code included for completeness)

To achieve this the onclick and onmousedown events are canceled by the function cancelEvent() which is a cross browser function to cancel the event. The cancelEvent() function also runs the restoreSelection() function because as the click event is cancelled the div doesn't receive focus and therefore nothing is selected at all unless this functions is run.

The variable isInFocus stores whether it is in focus and is changed to "false" onblur and "true" onfocus. This allows click events to be cancelled only if the div is not in focus (otherwise you would not be able to change the selection at all).

If you wish to the selection to be change when the div is focused by a click, and not restore the selection onclick (and only when focus is given to the element programtically using document.getElementById("area").focus(); or similar then simply remove the onclick and onmousedown events. The onblur event and the onDivBlur() and cancelEvent() functions can also safely be removed in these circumstances.

This code should work if dropped directly into the body of an html page if you want to test it quickly:

<div id="area" style="width:300px;height:300px;" onblur="onDivBlur();" onmousedown="return cancelEvent(event);" onclick="return cancelEvent(event);" contentEditable="true" onmouseup="saveSelection();" onkeyup="saveSelection();" onfocus="restoreSelection();"></div>
<script type="text/javascript">
var savedRange,isInFocus;
function saveSelection()
{
    if(window.getSelection)//non IE Browsers
    {
        savedRange = window.getSelection().getRangeAt(0);
    }
    else if(document.selection)//IE
    { 
        savedRange = document.selection.createRange();  
    } 
}

function restoreSelection()
{
    isInFocus = true;
    document.getElementById("area").focus();
    if (savedRange != null) {
        if (window.getSelection)//non IE and there is already a selection
        {
            var s = window.getSelection();
            if (s.rangeCount > 0) 
                s.removeAllRanges();
            s.addRange(savedRange);
        }
        else if (document.createRange)//non IE and no selection
        {
            window.getSelection().addRange(savedRange);
        }
        else if (document.selection)//IE
        {
            savedRange.select();
        }
    }
}
//this part onwards is only needed if you want to restore selection onclick
var isInFocus = false;
function onDivBlur()
{
    isInFocus = false;
}

function cancelEvent(e)
{
    if (isInFocus == false && savedRange != null) {
        if (e && e.preventDefault) {
            //alert("FF");
            e.stopPropagation(); // DOM style (return false doesn't always work in FF)
            e.preventDefault();
        }
        else {
            window.event.cancelBubble = true;//IE stopPropagation
        }
        restoreSelection();
        return false; // false = IE style
    }
}

You can set it to NULL.

> Data$genome <- NULL
> head(Data)
   chr region
1 chr1    CDS
2 chr1   exon
3 chr1    CDS
4 chr1   exon
5 chr1    CDS
6 chr1   exon

As pointed out in the comments, here are some other possibilities:

Data[2] <- NULL    # Wojciech Sobala
Data[[2]] <- NULL  # same as above
Data <- Data[,-2]  # Ian Fellows
Data <- Data[-2]   # same as above

You can remove multiple columns via:

Data[1:2] <- list(NULL)  # Marek
Data[1:2] <- NULL        # does not work!

Be careful with matrix-subsetting though, as you can end up with a vector:

Data <- Data[,-(2:3)]             # vector
Data <- Data[,-(2:3),drop=FALSE]  # still a data.frame

Ctrl+Shift+P, then "Convert Indentation to Tabs"

You can do this fairly easily with just straight JavaScript, no libraries required.

Enable a button

document.getElementById("Button").disabled=false;

Disable a button

 document.getElementById("Button").disabled=true;

No external libraries necessary.

This is a more efficient version of the solution from @Kramb. The existence check is redundant as the update where clause already handles this. Instead you just grab the rowcount and compare to batchsize.

Also note @Kramb solution didn't filter out already updated rows from the next iteration hence it would be an infinite loop.

Also uses the modern batch size syntax instead of using rowcount.

DECLARE @batchSize INT, @rowsUpdated INT
SET @batchSize = 1000;
SET @rowsUpdated = @batchSize; -- Initialise for the while loop entry

WHILE (@batchSize = @rowsUpdated)
BEGIN
    UPDATE TOP (@batchSize) TableName
    SET Value = 'abc1'
    WHERE Parameter1 = 'abc' AND Parameter2 = 123 and Value <> 'abc1';

    SET @rowsUpdated = @@ROWCOUNT;
END
