You can do it like this.

String to byte array

String stringToConvert = "This String is 76 characters long and will be converted to an array of bytes";
byte[] theByteArray = stringToConvert.getBytes();

http://www.javadb.com/convert-string-to-byte-array

Byte array to String

byte[] byteArray = new byte[] {87, 79, 87, 46, 46, 46};
String value = new String(byteArray);

http://www.javadb.com/convert-byte-array-to-string

(C++17 and above):

can use std::search also

This is also useful for searching sequence of elements.

#include <algorithm>
#include <iostream>
#include <vector>

template <typename Container>
bool search_vector(const Container& vec, const Container& searchvec)
{
    return std::search(vec.begin(), vec.end(), searchvec.begin(), searchvec.end()) != vec.end();
}

int main()
{
     std::vector<int> v = {2,4,6,8};

     //THIS WORKS. SEARCHING ONLY ONE ELEMENT.
     std::vector<int> searchVector1 = {2};
     if(search_vector(v,searchVector1))
         std::cout<<"searchVector1 found"<<std::endl;
     else
         std::cout<<"searchVector1 not found"<<std::endl;

     //THIS WORKS, AS THE ELEMENTS ARE SEQUENTIAL.
     std::vector<int> searchVector2 = {6,8};
     if(search_vector(v,searchVector2))
         std::cout<<"searchVector2 found"<<std::endl;
     else
         std::cout<<"searchVector2 not found"<<std::endl;

     //THIS WILL NOT WORK, AS THE ELEMENTS ARE NOT SEQUENTIAL.
     std::vector<int> searchVector3 = {8,6};
     if(search_vector(v,searchVector3))
         std::cout<<"searchVector3 found"<<std::endl;
     else
         std::cout<<"searchVector3 not found"<<std::endl;
}

Also there is flexibility of passing some search algorithms. Refer here.

https://en.cppreference.com/w/cpp/algorithm/search

This is the most exhaustive answer so far and gets rid of the need for a $i variable floating around. It is a combo of Kip and Gnarf's answers.

$array = array( 'cat' => 'meow', 'dog' => 'woof', 'cow' => 'moo', 'computer' => 'beep' );
foreach( array_keys( $array ) as $index=>$key ) {

    // display the current index + key + value
    echo $index . ':' . $key . $array[$key];

    // first index
    if ( $index == 0 ) {
        echo ' -- This is the first element in the associative array';
    }

    // last index
    if ( $index == count( $array ) - 1 ) {
        echo ' -- This is the last element in the associative array';
    }
    echo '<br>';
}

Hope it helps someone.

There is no error in the following piece of code:

float arr[4];
arr[0] = 6.28;
arr[1] = 2.50;
arr[2] = 9.73;
arr[3] = 4.364;
std::vector<float*> vec = std::vector<float*>();
vec.push_back(arr);
float* ptr = vec.front();
for (int i = 0; i < 3; i++)
    printf("%g\n", ptr[i]);

OUTPUT IS:

6.28

2.5

9.73

4.364

IN CONCLUSION:

std::vector<double*>

is another possibility apart from

std::vector<std::array<double, 4>>

that James McNellis suggested.

DateTime.ParseExact(monthName, "MMMM", CultureInfo.CurrentCulture ).Month

Although, for your purposes, you'll probably be better off just creating a Dictionary<string, int> mapping the month's name to its value.

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

Using the compiler to do implies memory leaks as the generated assemblies are loaded and never released. It's also less performant than using a real expression interpreter. For this purpose you can use Ncalc which is an open-source framework with this solely intent. You can also define your own variables and custom functions if the ones already included aren't enough.

Example:

Expression e = new Expression("2 + 3 * 5");
Debug.Assert(17 == e.Evaluate());

You can get deadlocks on more than just row locks, e.g. see this. The scripts may be competing for other resources, such as index blocks.

I've gotten around this in the past by engineering the parallelism in such a way that different instances are working on portions of the workload that are less likely to affect blocks that are close to each other; for example, for an update of a large table, instead of setting up the parallel slaves using something like MOD(n,10), I'd use TRUNC(n/10) which mean that each slave worked on a contiguous set of data.

There are, of course, much better ways of splitting up a job for parallelism, e.g. DBMS_PARALLEL_EXECUTE.

Not sure why you're getting "PL/SQL successfully completed", perhaps your scripts are handling the exception?

Several years ago I used JTidy for the same purpose:

http://jtidy.sourceforge.net/

"JTidy is a Java port of HTML Tidy, a HTML syntax checker and pretty printer. Like its non-Java cousin, JTidy can be used as a tool for cleaning up malformed and faulty HTML. In addition, JTidy provides a DOM interface to the document that is being processed, which effectively makes you able to use JTidy as a DOM parser for real-world HTML.

JTidy was written by Andy Quick, who later stepped down from the maintainer position. Now JTidy is maintained by a group of volunteers.

More information on JTidy can be found on the JTidy SourceForge project page ."

An example, just to make this a 15 seconds answer -

Say you have "styles.xaml" in a WPF library named "common" and you want to use it from your main application project:

1. Add a reference from the main project to "common" project
2. Your app.xaml should contain:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/Common;component/styles.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

including over directories can be processed by proxy file

• root
• .....|__web
• .....|.........|_requiredDbSettings.php
• .....|
• .....|___db
• .....|.........|_dbsettings.php
• .....|

• .....|_proxy.php

  dbsettings.php:
  $host='localhost';
  $user='username':
  $pass='pass';
  
  proxy.php:
  include_once 'db/dbsettings.php
  
  requiredDbSettings.php:
  include_once './../proxy.php';
  

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

Adding to the other great answers, we can use the Python logging library's debug(), info(), warning(), error(), and critical() methods. Quoting from the docs for Python 3.7.4,

There are three keyword arguments in kwargs which are inspected: exc_info which, if it does not evaluate as false, causes exception information to be added to the logging message.

What this means is, you can use the Python logging library to output a debug(), or other type of message, and the logging library will include the stack trace in its output. With this in mind, we can do the following:

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

def f():
    a = { 'foo': None }
    # the following line will raise KeyError
    b = a['bar']

def g():
    f()

try:
    g()
except Exception as e:
    logger.error(str(e), exc_info=True)

And it will output:

'bar'
Traceback (most recent call last):
  File "<ipython-input-2-8ae09e08766b>", line 18, in <module>
    g()
  File "<ipython-input-2-8ae09e08766b>", line 14, in g
    f()
  File "<ipython-input-2-8ae09e08766b>", line 10, in f
    b = a['bar']
KeyError: 'bar'

For those who want to just copy and paste the fastest implementation of shift, there is a benchmark and conclusion(see the end). In addition, I introduce fill_value parameter and fix some bugs.

Benchmark

import numpy as np
import timeit

# enhanced from IronManMark20 version
def shift1(arr, num, fill_value=np.nan):
    arr = np.roll(arr,num)
    if num < 0:
        arr[num:] = fill_value
    elif num > 0:
        arr[:num] = fill_value
    return arr

# use np.roll and np.put by IronManMark20
def shift2(arr,num):
    arr=np.roll(arr,num)
    if num<0:
         np.put(arr,range(len(arr)+num,len(arr)),np.nan)
    elif num > 0:
         np.put(arr,range(num),np.nan)
    return arr

# use np.pad and slice by me.
def shift3(arr, num, fill_value=np.nan):
    l = len(arr)
    if num < 0:
        arr = np.pad(arr, (0, abs(num)), mode='constant', constant_values=(fill_value,))[:-num]
    elif num > 0:
        arr = np.pad(arr, (num, 0), mode='constant', constant_values=(fill_value,))[:-num]

    return arr

# use np.concatenate and np.full by chrisaycock
def shift4(arr, num, fill_value=np.nan):
    if num >= 0:
        return np.concatenate((np.full(num, fill_value), arr[:-num]))
    else:
        return np.concatenate((arr[-num:], np.full(-num, fill_value)))

# preallocate empty array and assign slice by chrisaycock
def shift5(arr, num, fill_value=np.nan):
    result = np.empty_like(arr)
    if num > 0:
        result[:num] = fill_value
        result[num:] = arr[:-num]
    elif num < 0:
        result[num:] = fill_value
        result[:num] = arr[-num:]
    else:
        result[:] = arr
    return result

arr = np.arange(2000).astype(float)

def benchmark_shift1():
    shift1(arr, 3)

def benchmark_shift2():
    shift2(arr, 3)

def benchmark_shift3():
    shift3(arr, 3)

def benchmark_shift4():
    shift4(arr, 3)

def benchmark_shift5():
    shift5(arr, 3)

benchmark_set = ['benchmark_shift1', 'benchmark_shift2', 'benchmark_shift3', 'benchmark_shift4', 'benchmark_shift5']

for x in benchmark_set:
    number = 10000
    t = timeit.timeit('%s()' % x, 'from __main__ import %s' % x, number=number)
    print '%s time: %f' % (x, t)

benchmark result:

benchmark_shift1 time: 0.265238
benchmark_shift2 time: 0.285175
benchmark_shift3 time: 0.473890
benchmark_shift4 time: 0.099049
benchmark_shift5 time: 0.052836

Conclusion

shift5 is winner! It's OP's third solution.

You can use the utility method in Collections class public static <T extends Comparable<? super T>> void sort(List<T> list) or

public static <T> void sort(List<T> list,Comparator<? super T> c)

Refer to Comparable and Comparator interfaces for more flexibility on sorting the object.

Center iframe

One solution is:

  text-align:center;
  width:100%;
}
iframe{

Unlike standard arithmetic, which desires matching dimensions, dot products require that the dimensions are one of:

• (X..., A, B) dot (Y..., B, C) -> (X..., Y..., A, C), where ... means "0 or more different values
• (B,) dot (B, C) -> (C,)
• (A, B) dot (B,) -> (A,)
• (B,) dot (B,) -> ()

Your problem is that you are using np.matrix, which is totally unnecessary in your code - the main purpose of np.matrix is to translate a * b into np.dot(a, b). As a general rule, np.matrix is probably not a good choice.

Below code worked for me:

string _stDate = Convert.ToDateTime(DateTime.Today.AddMonths(-12)).ToString("MM/dd/yyyy");
String format ="MM/dd/yyyy";
IFormatProvider culture = new System.Globalization.CultureInfo("fr-FR", true);
DateTime _Startdate = DateTime.ParseExact(_stDate, format, culture);

Use array_diff() for 1 line solution:

$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi', 'strawberry'); //throw in another 'strawberry' to demonstrate that it removes multiple instances of the string
$array_without_strawberries = array_diff($array, array('strawberry'));
print_r($array_without_strawberries);

...No need for extra functions or foreach loop.

Java 7+, commons.io

public final class ZipUtils {

    public static void zipFolder(final File folder, final File zipFile) throws IOException {
        zipFolder(folder, new FileOutputStream(zipFile));
    }

    public static void zipFolder(final File folder, final OutputStream outputStream) throws IOException {
        try (ZipOutputStream zipOutputStream = new ZipOutputStream(outputStream)) {
            processFolder(folder, zipOutputStream, folder.getPath().length() + 1);
        }
    }

    private static void processFolder(final File folder, final ZipOutputStream zipOutputStream, final int prefixLength)
            throws IOException {
        for (final File file : folder.listFiles()) {
            if (file.isFile()) {
                final ZipEntry zipEntry = new ZipEntry(file.getPath().substring(prefixLength));
                zipOutputStream.putNextEntry(zipEntry);
                try (FileInputStream inputStream = new FileInputStream(file)) {
                    IOUtils.copy(inputStream, zipOutputStream);
                }
                zipOutputStream.closeEntry();
            } else if (file.isDirectory()) {
                processFolder(file, zipOutputStream, prefixLength);
            }
        }
    }
}

It will create a table and copy all the data from old table to new table

SELECT * INTO event_log_temp FROM event_log

And you can clear the old table data.

DELETE FROM event_log

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

Simplest example to making any function in jQuery is

jQuery.fn.extend({
    exists: function() { return this.length }
});

if($(selector).exists()){/*do something here*/}

You can also just use the pipeline with the AddScript Method:

string cmdArg = ".\script.ps1 -foo bar"            
Collection<PSObject> psresults;
using (Pipeline pipeline = _runspace.CreatePipeline())
            {
                pipeline.Commands.AddScript(cmdArg);
                pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
                psresults = pipeline.Invoke();
            }
return psresults;

It will take a string, and whatever parameters you pass it.

I finally found the problem. The error was not the good one.

Apparently, Ole DB source have a bug that might make it crash and throw that error. I replaced the OLE DB destination with a OLE DB Command with the insert statement in it and it fixed it.

Strange Bug, Hope it will help other people.

I'm not sure how you want to use the file names, but one of these should help:

• If you just want to see the names, you can use something like gulp-debug, which lists the details of the vinyl file. Insert this anywhere you want a list, like so:

  var gulp = require('gulp'),
      debug = require('gulp-debug');
  
  gulp.task('examples', function() {
      return gulp.src('./examples/*.html')
          .pipe(debug())
          .pipe(gulp.dest('./build'));
  });
  

• Another option is gulp-filelog, which I haven't used, but sounds similar (it might be a bit cleaner).

• Another options is gulp-filesize, which outputs both the file and it's size.

• If you want more control, you can use something like gulp-tap, which lets you provide your own function and look at the files in the pipe.

Since the answer for me was buried in the comments. For SQL Server 2012 and beyond, you can use the following:

BACKUP LOG Database TO DISK='NUL:'
DBCC SHRINKFILE (Database_Log, 1)

I think there is no out-of-the-box support for that in VS Code.

You can install a plugin to give you similar functionality. Eg.:

https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints

Or the more famous:

https://marketplace.visualstudio.com/items?itemName=xyz.local-history

Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore file also solves this problem).

Controller:

return redirect()->route('subscriptions.index')->withSuccess(['Success Message here!']);

Blade

@if (session()->has('success'))
<div class="alert alert-success">
    @if(is_array(session('success')))
        <ul>
            @foreach (session('success') as $message)
                <li>{{ $message }}</li>
            @endforeach
        </ul>
    @else
        {{ session('success') }}
    @endif
</div>
@endif

You can always save this part as separate blade file and include it easily. fore example:

<div class="row">
        <div class="col-md-6">
            @include('admin.system.success')
            <div class="box box-widget">

You must pass an int in the argument.

First Example:

view.setBackgroundColor(-500136)

Second Example:

int colorId = R.color.green;

view.setBackgroundResource(colorId);

If you are just storing it for reference, you can store it as a string, but if you want to do a lookup, for example, to see if the IP address is in some table, you need a "canonical representation." Converting the entire thing to a (large) number is the right thing to do. IPv4 addresses can be stored as a long int (32 bits) but you need a 128 bit number to store an IPv6 address.

For example, all these strings are really the same IP address: 127.0.0.1, 127.000.000.001, ::1, 0:0:0:0:0:0:0:1

Do not erase and then increment the iterator. No need to increment, if your vector has an odd (or even, I don't know) number of elements you will miss the end of the vector.

The initial problem is that the the configuration specifies a property suffix=".jsp" so the ViewResolver implementing class will add .jsp to the end of the view name being returned from your method.

However since you commented out the InternalResourceViewResolver then, depending on the rest of your application configuration, there might not be any other ViewResolver registered. You might find that nothing is working now.

Since .html files are static and do not require processing by a servlet then it is more efficient, and simpler, to use an <mvc:resources/> mapping. This requires Spring 3.0.4+.

For example:

<mvc:resources mapping="/static/**" location="/static/" />

which would pass through all requests starting with /static/ to the webapp/static/ directory.

So by putting index.html in webapp/static/ and using return "static/index.html"; from your method, Spring should find the view.

$host.version is just plain wrong/unreliable. This gives you the version of the hosting executable (powershell.exe, powergui.exe, powershell_ise.exe, powershellplus.exe etc) and not the version of the engine itself.

The engine version is contained in $psversiontable.psversion. For PowerShell 1.0, this variable does not exist, so obviously if this variable is not available it is entirely safe to assume the engine is 1.0, obviously.

If you add:

<meta http-equiv="content-type" content="text/plain; charset=UTF-8"/>

in the head of the document it will start working as expected:

Updated Fiddle Here.

Try this Int-based workaround:

extension String {
    // start and end is included
    func intBasedSubstring(_ start: Int, _ end: Int) -> String {
        let endOffset: Int = -(count - end - 1)
        let startIdx = self.index(startIndex, offsetBy: start)
        let endIdx = self.index(endIndex, offsetBy: endOffset)
        return String(self[startIdx..<endIdx])
    }
}

Note: It's just a practice. It doesn't check the boundary. Modify to suit your needs.

the simple straight way i went about this similar was - navigate to my project folder using cd command prompt - type in composer inside cdm to be sure its installed - if yes then type composer require ../the extension u intended to install

Try this (on the guest machine. i.e. the OS running in the Virtual box):

sudo adduser your-user vboxsf

Now reboot the OS running in the virtual box.

The above answer is not according to what Google Doc Referred for Location Tracking in Google api v2.

I just followed the official tutorial and ended up with this class that is fetching the current location and centring the map on it as soon as i get that.

you can extend this class to have LocationReciever to have periodic Location Update. I just executed this code on api level 7

I found myself doing .allValues alot throughout my code. I finally figured out a way to simply conform to an Iteratable protocol and have an rawValues() method.

protocol Iteratable {}
extension RawRepresentable where Self: RawRepresentable {

    static func iterateEnum<T: Hashable>(_: T.Type) -> AnyIterator<T> {
        var i = 0
        return AnyIterator {
            let next = withUnsafePointer(to: &i) {
                $0.withMemoryRebound(to: T.self, capacity: 1) { $0.pointee }
            }
            if next.hashValue != i { return nil }
            i += 1
            return next
        }
    }
}

extension Iteratable where Self: RawRepresentable, Self: Hashable {
    static func hashValues() -> AnyIterator<Self> {
        return iterateEnum(self)
    }

    static func rawValues() -> [Self.RawValue] {
        return hashValues().map({$0.rawValue})
    }
}


// Example
enum Grocery: String, Iteratable {
    case Kroger = "kroger"
    case HEB = "h.e.b."
    case Randalls = "randalls"
}

let groceryHashes = Grocery.hashValues() // AnyIterator<Grocery>
let groceryRawValues = Grocery.rawValues() // ["kroger", "h.e.b.", "randalls"]

Just remove activation section, I don't know why -Pdev1 doesn't override default false activation. But if you omit this:

<activation> <activeByDefault>false</activeByDefault> </activation>

then your profile will be activated only after explicit declaration as -Pdev1

//arraylist/Pojo you can Pass using bundle  like this 
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
Bundle args = new Bundle();
                        args.putSerializable("imageSliders",(Serializable)allStoriesPojo.getImageSliderPojos());
                        intent.putExtra("BUNDLE",args);
 startActivity(intent); 


Get SecondActivity like this
  Intent intent = getIntent();
        Bundle args = intent.getBundleExtra("BUNDLE");
String filter = bundle.getString("imageSliders");

 foreach (string file in System.IO.Directory.GetFiles(path))
 {
    System.IO.File.Delete(file);
 }

 foreach (string subDirectory in System.IO.Directory.GetDirectories(path))
 {
     System.IO.Directory.Delete(subDirectory,true); 
 } 

Use os.rename. But you have to pass full path of both files to the function. If I have a file a.txt on my desktop so I will do and also I have to give full of renamed file too.

os.rename('C:\\Users\\Desktop\\a.txt', 'C:\\Users\\Desktop\\b.kml')

Yes.. It is possible using css

<a class="disable-me" href="page.html">page link</a>

.disable-me {
    pointer-events: none;
}

I did this a bit different. In my gridview I set the AutoGenerateDeleteButton="true". To find the delete button I use jQuery and add a click event to the found Anchors.

jQuery("a").filter(function () {
        return this.innerHTML.indexOf("Delete") == 0;
        }).click(function () { return confirm("Are you sure you want to delete this record?"); 
});

This is quick and simple for what I need to do. Just be mindful that Every Anchor in the page that displays Delete will be selected by jQuery and will have the event added to it.

Bear in mind that 0 is a special case of parameter numbers inside a batch file, where 0 means this file as given on the command line.

So if the file is myfile.bat, you could call it in several ways as follows, each of which would give you a different output from the %0 or %~0 usage:

myfile

myfile.bat

mydir\myfile.bat

c:\mydir\myfile.bat

"c:\mydir\myfile.bat"

All of the above are legal calls if you call it from the correct relative place to the directory in which it exists. %~0 strips the quotes from the last example, whereas %0 does not.

Because these all give different results, %0 and %~0 are very unlikely to be what you actually want to use.

Here's a batch file to illustrate:

@echo Full path and filename: %~f0
@echo Drive: %~d0
@echo Path: %~p0
@echo Drive and path: %~dp0
@echo Filename without extension: %~n0
@echo Filename with    extension: %~nx0
@echo Extension: %~x0
@echo Filename as given on command line: %0
@echo Filename as given on command line minus quotes: %~0
@REM Build from parts
@SETLOCAL
@SET drv=%~d0
@SET pth=%~p0
@SET fpath=%~dp0
@SET fname=%~n0
@SET ext=%~x0
@echo Simply Constructed name: %fpath%%fname%%ext%
@echo Fully  Constructed name: %drv%%pth%%fname%%ext%
@ENDLOCAL
pause

q  = [1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5]
vm = [-1, -1, -1, -1,1,2,3,1]

p = []
for v in vm:
    if v in q:
        p.append(q.index(v))
    else:
        p.append(99999)

print p
p = [q.index(v) if v in q else 99999 for v in vm]
print p

Output:

[99999, 99999, 99999, 99999, 0, 1, 2, 0]
[99999, 99999, 99999, 99999, 0, 1, 2, 0]

Instead of using append() in the list comprehension you can reference the p as direct output, and use q.index(v) and 99999 in the LC.

Not sure if this is intentional but note that q.index(v) will find just the first occurrence of v, even tho you have several in q. If you want to get the index of all v in q, consider using a enumerator and a list of already visited indexes

Something in those lines(pseudo-code):

visited = []
for i, v in enumerator(vm):
   if i not in visited:
       p.append(q.index(v))
   else:
       p.append(q.index(v,max(visited))) # this line should only check for v in q after the index of max(visited)
   visited.append(i)

The simplest way is using Ergo as your reverse proxy: https://github.com/cristianoliveira/ergo

You set your services and its IP:PORT and ergo routes it for you :).

You can achieve the same using nginx or apache but you will need to configure them.

module.exports and exports both point to the same object before the module is evaluated.

Any property you add to the module.exports object will be available when your module is used in another module using require statement. exports is a shortcut made available for the same thing. For instance:

module.exports.add = (a, b) => a+b

is equivalent to writing:

exports.add = (a, b) => a+b

So it is okay as long as you do not assign a new value to exports variable. When you do something like this:

exports = (a, b) => a+b 

as you are assigning a new value to exports it no longer has reference to the exported object and thus will remain local to your module.

If you are planning to assign a new value to module.exports rather than adding new properties to the initial object made available, you should probably consider doing as given below:

module.exports = exports = (a, b) => a+b

Node.js website has a very good explanation of this.

For applications such as Squirrel SQL Client (http://squirrel-sql.sourceforge.net/) version 4 you can set "serverTimezone" under "driver properties" to GMT+1 (example of timezone "Europe/Vienna).

Your code (or some code called by you) is making a call to a COM method which is returning an unknown value. If you can find that then you're half way there.

You could try breaking when the exception is thrown. Go to Debug > Exceptions... and use the Find... option to locate System.Runtime.InteropServices.COMException. Tick the option to break when it's thrown and then debug your application.

Hopefully it will break somewhere meaningful and you'll be able to trace back and find the source of the error.

Try instead of db.parse(xml):

Document doc = db.parse(new InputSource(new StringReader(**xml**)));

I like Cohens answer, but a more technical definition is: Your code calls a library. A framework calls your code. For example a GUI framework calls your code through event-handlers. A web framework calls your code through some request-response model.

This is also called inversion of control - suddenly the framework decides when and how to execute you code rather than the other way around as with libraries. This means that a framework also have a much larger impact on how you have to structure your code.

Is there a name to describe this idiom?

In UML it is called aggregation. It differs from composition in that the member object is not owned by the referring class. In C++ you can implement aggregation in two different ways, through references or pointers.

I am assuming it is to prevent the possibly large overhead of copying a big complex object?

No, that would be a really bad reason to use this. The main reason for aggregation is that the contained object is not owned by the containing object and thus their lifetimes are not bound. In particular the referenced object lifetime must outlive the referring one. It might have been created much earlier and might live beyond the end of the lifetime of the container. Besides that, the state of the referenced object is not controlled by the class, but can change externally. If the reference is not const, then the class can change the state of an object that lives outside of it.

Is this generally good practice? Are there any pitfalls to this approach?

It is a design tool. In some cases it will be a good idea, in some it won't. The most common pitfall is that the lifetime of the object holding the reference must never exceed the lifetime of the referenced object. If the enclosing object uses the reference after the referenced object was destroyed, you will have undefined behavior. In general it is better to prefer composition to aggregation, but if you need it, it is as good a tool as any other.

There is no difference between those two imports you state. You can, however, use the static import to allow unqualified access to static members of other classes. Where I used to have to do this:

import org.apache.commons.lang.StringUtils;
      .
      .
      .
if (StringUtils.isBlank(aString)) {
      .
      .
      .

I can do this:

import static org.apache.commons.lang.StringUtils.isBlank;
      .
      .
      .
if (isBlank(aString)) {
      .
      .
      .

You can see more in the documentation.

If strMyString.Contains("Something") or strMyString.Contains("Something2") Then

End if

The error indicates that the compiler thinks you want to do a bitwise OR on a Boolean and a string. Which of course won't work.

Note the standard sed syntax (as in POSIX, so supported by all conforming sed implementations around (GNU, OS/X, BSD, Solaris...)):

sed '/CLIENTSCRIPT=/a\
CLIENTSCRIPT2="hello"' file

Or on one line:

sed -e '/CLIENTSCRIPT=/a\' -e 'CLIENTSCRIPT2="hello"' file

(-expressions (and the contents of -files) are joined with newlines to make up the sed script sed interprets).

The -i option for in-place editing is also a GNU extension, some other implementations (like FreeBSD's) support -i '' for that.

Alternatively, for portability, you can use perl instead:

perl -pi -e '$_ .= qq(CLIENTSCRIPT2="hello"\n) if /CLIENTSCRIPT=/' file

Or you could use ed or ex:

printf '%s\n' /CLIENTSCRIPT=/a 'CLIENTSCRIPT2="hello"' . w q | ex -s file

Sometimes I found myself deleting the migration file and then deleting the corresponding entry on the table schema_migrations from the database. Not pretty but it works.

If you're using SQL Server, you can set the value of bit fields with 0 and 1

or

'true' and 'false' (yes, using strings)

...your_bit_field='false'... => equivalent to 0

A useful feature for this is using static

As others have said, you have to create a class for your globals:

public static class Globals {
    public const float PI = 3.14;
}

But you can import it like this in order to no longer write the class name in front of its static properties:

using static Globals;
[...]
Console.WriteLine("Pi is " + PI);

Here is my solution (derived from SaraubhM's answer)

**Jump To**: [Hotkeys & Markers](#hotkeys-markers) / [Radii](#radii) / [Route Wizard 2.0](#route-wizard-2-0)

Which gives you:

Jump To: Hotkeys & Markers / Radii / Route Wizard 2.0

Here's some background on the mechanism you should use, called Package Configurations: Understanding Integration Services Package Configurations. The article describes 5 types of configurations:

• XML configuration file
• Environment variable
• Registry entry
• Parent package variable
• SQL Server

Here's a walkthrough of setting up a configuration on a Connection Manager: SQL Server Integration Services SSIS Package Configuration - I do realize this is using an environment variable for the connection string (not a great idea), but the basics are identical to using an XML file. The only step(s) you have to change in that walkthrough are the configuration type, and then a path.

From Save (Not Permitted) Dialog Box on MSDN :

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column <<<<

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

See Also Colt Kwong Blog Entry:
Saving changes is not permitted in SQL 2008 Management Studio

You can access your files via SSL like this:

https://s3.amazonaws.com/bucket_name/images/logo.gif

If you use a custom domain for your bucket, you can use S3 and CloudFront together with your own SSL certificate (or generate a free one via Amazon Certificate Manager): http://aws.amazon.com/cloudfront/custom-ssl-domains/

Save the plot as png

plt.savefig("temp.png")

You can also use

 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
  {

   [self.yourTextField resignFirstResponder];

  }

Best one if You have many Uitextfields :

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
 {    
     [self.view endEditing:YES];
 }

Otherwise for old version, if '--show-item' is not recognize, you can use the following command :

svn log -r HEAD | grep -o -E "^r[0-9]{1,}" | sed 's/r//g'

Hope it helps.

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?

angular-charts is a library I wrote for creating charts with angular and D3.

It encapsulates basic charts that can be created using D3 in one angular directive. Also it offers features such as

1. One click chart change;
2. Auto tooltips;
3. Auto adjustment to containers;
4. Legends;
5. Simple data format: only define what you on x and what you need on y;

There is a angular-charts demo available.

All of the replies with readonly are only suitable when this is a pure TS environment - if it's ever being made into a library then this doesn't actually prevent anything, it just provides warnings for the TS compiler itself.

Static is also not correct - that's adding a method to the Class, not to an instance of the class - so you need to address it directly.

There are several ways to manage this, but the pure TS way is to use a getter - exactly as you have done already.

The alternative way is to put it in as readonly, but then use Object.defineProperty to lock it - this is almost the same thing that is being done via the getter, but you can lock it to have a value, rather than a method to use to get it -

class MyClass {
    MY_CONSTANT = 10;

    constructor() {
        Object.defineProperty(this, "MY_CONSTANT", {value: this.MY_CONSTANT});
    }
}

The defaults make it read-only, but check out the docs for more details.

Is there an alternative which works 100% of the time?

No

There are several questions you need to ask yourself before choosing a lowercasing method.

1. How is the string encoded? plain ASCII? UTF-8? some form of extended ASCII legacy encoding?
2. What do you mean by lower case anyway? Case mapping rules vary between languages! Do you want something that is localised to the users locale? do you want something that behaves consistently on all systems your software runs on? Do you just want to lowercase ASCII characters and pass through everything else?
3. What libraries are available?

Once you have answers to those questions you can start looking for a soloution that fits your needs. There is no one size fits all that works for everyone everywhere!

You can encode your string by using .encode()

Example:

'Hello World'.encode()

I just used post and an if:

data = getDataObjectByForm(form);
var jqxhr = $.post(url, data, function(){}, 'json')
    .done(function (response) {
        if (response instanceof Object)
            var json = response;
        else
            var json = $.parseJSON(response);
        // console.log(response);
        // console.log(json);
        jsonToDom(json);
        if (json.reload != undefined && json.reload)
            location.reload();
        $("body").delay(1000).css("cursor", "default");
    })
    .fail(function (jqxhr, textStatus, error) {
        var err = textStatus + ", " + error;
        console.log("Request Failed: " + err);

The Top Voted Answer is out of date. I just installed MySQL 5.7 and the service name is now MySQL57 so the new command is

net stop MySQL57

The column names which are mixed case or uppercase have to be double quoted in PostgresQL. So best convention will be to follow all small case with underscore.

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

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

Controller's Action Method

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

Jquery GET

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

Person class

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

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

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

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

For more information check Posting JSON Data to MVC Controllers Here

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

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

View

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

Action Method

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

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

Suitable for when you need to Get data from database

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

I hope this will help to you.

Here's a good example:

int number = 1;
//D4 = pad with 0000
string outputValue = String.Format("{0:D4}", number);
Console.WriteLine(outputValue);//Prints 0001
//OR
outputValue = number.ToString().PadLeft(4, '0');
Console.WriteLine(outputValue);//Prints 0001 as well

Some extensions like blocksite use the accessibility service API to deploy extension like features to Chrome on Android. Might be worth a look through the play store. Otherwise, Firefox is your best bet, though many extensions don't work on mobile for some reason.

Just remove the ( and the ) on your SELECT statement:

insert into table2 (Name, Subject, student_id, result)
select Name, Subject, student_id, result
from table1;

There could be many reasons for Index not being used. Even after you specify hints, there are chances Oracle optimizer thinks otherwise and decide not to use Index. You need to go through the EXPLAIN PLAN part and see what is the cost of the statement with INDEX and without INDEX.

Assuming the Oracle uses CBO. Most often, if the optimizer thinks the cost is high with INDEX, even though you specify it in hints, the optimizer will ignore and continue for full table scan. Your first action should be checking DBA_INDEXES to know when the statistics are LAST_ANALYZED. If not analyzed, you can set table, index for analyze.

begin 
   DBMS_STATS.GATHER_INDEX_STATS ( OWNNAME=>user
                                 , INDNAME=>IndexName);
end;

For table.

begin 
   DBMS_STATS.GATHER_TABLE_STATS ( OWNNAME=>user
                                 , TABNAME=>TableName);
end;

In extreme cases, you can try setting up the statistics on your own.

No, there is no better way.

Actually you have an error in your pattern. What you want is:

DecimalFormat df = new DecimalFormat("#.00"); 

Note the "00", meaning exactly two decimal places.

If you use "#.##" (# means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d); prints just "3", not "3.00".

The accepted answer would rule out a lot of valid identifiers, as far as I can see. Here is a regular expression that I put together which should follow the spec (see chapter 7.6 on identifiers). Created it using RegexBuddy and you can find an export of the explanation at http://samples.geekality.net/js-identifiers.

^[$_\p{L}][$_\p{L}\p{Mn}\p{Mc}\p{Nd}\p{Pc}\u200C\u200D]*+$

In addition, the name cannot be one of the following reserved words.

break, do, instanceof, typeof, case, else, new, var, catch, finally, return, void, continue, for, switch, while, debugger, function, this, with, default, if, throw, delete, in, try, class, enum, extends, super, const, export, import, implements, let, private, public, yield, interface, package, protected, static, null, true, false

Your variable is set correctly by testvar=$(cat test.txt). To display this variable which consist new line characters, simply add double quotes, e.g.

echo "$testvar" 

Here is the full example:

$ printf "test1\ntest2" > test.txt
$ testvar=$(<test.txt)
$ grep testvar <(set)
testvar=$'test1\ntest2'
$ echo "$testvar"
text1
text2
$ printf "%b" "$testvar"
text1
text2

You can create a new dict for each pair and merge it with the previous dict:

reduce(lambda p, q: {**p, **{q[0]: q[1]}}, bla bla bla, {})

Obviously this approaches requires reduce from functools.

The accepted answer helped me but I got tripped up while doing concatenation of varchars involving case statements. I know the OP's question does not involve case statements but I thought this would be helpful to post here for others like me who ended up here while struggling to build long dynamic SQL statements involving case statements.

When using case statements with string concatenation the rules mentioned in the accepted answer apply to each section of the case statement independently.

declare @l_sql varchar(max) = ''

set @l_sql = @l_sql +
case when 1=1 then
    --without this correction the result is truncated
    --CONVERT(VARCHAR(MAX), '')
 +REPLICATE('1', 8000)
 +REPLICATE('1', 8000)
end

print len(@l_sql)

Yes it is.

In Python a function doesn't always have to return a variable of the same type (although your code will be more readable if your functions do always return the same type). That means that you can't specify a single return type for the function.

In the same way, the parameters don't always have to be the same type too.

Based on Tim Down's answer, but it checks for the last known "good" text row. It places the cursor at the very end.

Furthermore, I could also recursively/iteratively check the last child of each consecutive last child to find the absolute last "good" text node in the DOM.

  setCaret(document.getElementById("editable"));_x000D_
}_x000D_

Valgrind can show detailed information, but it slows down the target application significantly, and most of the time it changes the behavior of the application.

Exmap was something I didn't know yet, but it seems that you need a kernel module to get the information, which can be an obstacle.

I assume what everyone wants to know with respect to "memory usage" is the following... In Linux, the amount of physical memory a single process might use can be roughly divided into following categories.

• M.a anonymous mapped memory

• .p private

  • .d dirty == malloc/mmapped heap and stack allocated and written memory
  • .c clean == malloc/mmapped heap and stack memory once allocated, written, then freed, but not reclaimed yet

• .s shared

  • .d dirty == malloc/mmaped heap could get copy-on-write and shared among processes (edited)
  • .c clean == malloc/mmaped heap could get copy-on-write and shared among processes (edited)

• M.n named mapped memory

• .p private

  • .d dirty == file mmapped written memory private
  • .c clean == mapped program/library text private mapped

• .s shared

  • .d dirty == file mmapped written memory shared
  • .c clean == mapped library text shared mapped

Utility included in Android called showmap is quite useful

TLDR: In one line the command you are looking for:

angular.element(document.body).injector().get('serviceName')

Deep dive

AngularJS uses Dependency Injection (DI) to inject services/factories into your components,directives and other services. So what you need to do to get a service is to get the injector of AngularJS first (the injector is responsible for wiring up all the dependencies and providing them to components).

To get the injector of your app you need to grab it from an element that angular is handling. For example if your app is registered on the body element you call injector = angular.element(document.body).injector()

From the retrieved injector you can then get whatever service you like with injector.get('ServiceName')

More information on that in this answer: Can't retrieve the injector from angular
And even more here: Call AngularJS from legacy code

Another useful trick to get the $scope of a particular element. Select the element with the DOM inspection tool of your developer tools and then run the following line ($0 is always the selected element):
angular.element($0).scope()

Daniel LeCheminant's code didn't work for me after converting it from CoffeeScript to JavaScript (js2coffee). It kept bombing out on the _.defer() line.

I assumed this was something to do with jQuery deferreds, so I changed it to $.Deferred() and it's working now. I tested it in Internet Explorer 11, Firefox 35, and Chrome 39 with jQuery 2.1.1. The usage is the same as described in Daniel's post.

Try escaping the single quote with a single quote:

Replace(@strip, '''', '')

Work for me :)

function jsonEncodeArray( $array ){
    array_walk_recursive( $array, function(&$item) {

}

As to the short script, the following runs on my Linux host

#!/bin/bash
HOST_DIR=<pull-to>
DEVICE_DIR=/sdcard/<pull-from>
EXTENSION="\.jpg"

while read MYFILE ; do
    adb pull "$DEVICE_DIR/$MYFILE" "$HOST_DIR/$MYFILE"
done < $(adb shell ls -1 "$DEVICE_DIR" | grep "$EXTENSION")

"ls minus one" lets "ls" show one file per line, and the quotation marks allow spaces in the filename.

The general syntax, as depicted already is:

std::vector<std::vector<int> > v (A_NUMBER, std::vector <int> (OTHER_NUMBER, DEFAULT_VALUE))  

Here, the vector 'v' can be visualised as a two dimensional array, with 'A_NUMBER' of rows, with 'OTHER_NUMBER' of columns with their initial value set to 'DEFAULT_VALUE'.

Also it can be written like this:

std::vector <int> line(OTHER_NUMBER, DEFAULT_VALUE)
std::vector<std::vector<int> > v(A_NUMBER, line)

Inputting values in a 2-D vector is similar to inputting values in a 2-D array:

for(int i = 0; i < A_NUMBER; i++) {
     for(int j = 0; j < OTHER_NUMBER; j++) {
         std::cin >> v[i][j]
     }
}

Examples have already been stated in other answers....!

You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#parent-selector

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

You can create a generic extension method and then use it on the object like:

public static class Extensions
{
    public static KeyValuePair<TKey, TValue> ToKeyValuePair<TKey, TValue>(this Object obj)
    {
        // if obj is null throws exception
        Contract.Requires(obj != null);

        // gets the type of the obj parameter
        var type = obj.GetType();
        // checks if obj is of type KeyValuePair
        if (type.IsGenericType && type == typeof(KeyValuePair<TKey, TValue>))
        {

            return new KeyValuePair<TKey, TValue>(
                                                    (TKey)type.GetProperty("Key").GetValue(obj, null), 
                                                    (TValue)type.GetProperty("Value").GetValue(obj, null)
                                                 );

        }
        // if obj type does not match KeyValuePair throw exception
        throw new ArgumentException($"obj argument must be of type KeyValuePair<{typeof(TKey).FullName},{typeof(TValue).FullName}>");   
 }

and usage would be like:

KeyValuePair<string,long> kvp = obj.ToKeyValuePair<string,long>();

You need to use the border property as seen here: jsFiddle

HTML:

<table width="770">
    <tr>
        <td class="border-left-bottom">picture (border only to the left and bottom ) </td>
        <td>text</td>
    </tr>
    <tr>
        <td>text</td>
        <td class="border-left-bottom">picture (border only to the left and bottom) </td>
    </tr>
</table>`

CSS:

td.border-left-bottom{
    border-left: solid 1px #000;
    border-bottom: solid 1px #000;
}

First, set your key field. Then include your other fields:

var results = 
    persons
    .GroupBy(n => n.PersonId)
    .Select(r => new Result {PersonID = r.Key, Cars = r.ToList() })
    .ToList()

Indeed. The thing is that the 2008 R2 version is very tricky. The JTDs driver seems to work on some cases. In a certain server, the jTDS worked fine for an 2008 R2 instance. In another server, though, I had to use Microsoft's JBDC driver sqljdbc4.jar. But then, it would only work after setting the JRE environment to 1.6(or higher).

I used 1.5 for the other server, so I waisted a lot of time on this.

Tricky issue.

C# code:

            var jsonSerializerSettings = new JsonSerializerSettings
            {
                ReferenceLoopHandling = ReferenceLoopHandling.Serialize,
                PreserveReferencesHandling = PreserveReferencesHandling.Objects,
            };

            var jsonString = JsonConvert.SerializeObject(object2Serialize, jsonSerializerSettings);

            var filePath = @"E:\json.json";

            File.WriteAllText(filePath, jsonString);

With ggplot2:

p<-qplot(spray,count,data=InsectSprays,geom='boxplot')
p<-p+stat_summary(fun.y=mean,shape=1,col='red',geom='point')
print(p)

Managed to get answer after do some google..

If s is your string than you could do it this way:

Mid(s, index, 1)

Edit based on comment below question.

It seems that you need a bit different approach which should be easier. Try in this way:

Dim character As String 'Integer if for numbers
's = ActiveDocument.Content.Text - we don't need it
character = Activedocument.Characters(index)

This worked for me for deserializing JSON into an array of objects:

List<TheUser> friends = JsonConvert.DeserializeObject<List<TheUser>>(response);

You're missing comma (,) inbetween:

>>> ((1,2) (2,3))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable

Put comma:

>>> ((1,2), (2,3))
((1, 2), (2, 3))

I believe you should do

dice1 = arc4random_uniform(6) + 1;

to get the range 1 - 6. I don't do iOS objective C nor have I any knowledge on swift-language though. The random method should return a value between 0 and 5, and + 1 will make it a value between 1 and 6.

If you need a range between lets say 10 - 30 then just do

int random = arc4random_uniform(21) + 10;

You simply forgot to supply an argument to -i. Just change -i to -i ''.

Of course that means you don't want your files to be backed up; otherwise supply your extension of choice, like -i .bak.

If you're talking about PL/SQL, you should put it in an anonymous block.

DECLARE
    v_text VARCHAR2(10); -- declare
BEGIN
    v_text := 'Hello';  --assign
    dbms_output.Put_line(v_text); --display
END; 

Since I consider it relevant and elegant enough (no need to specify coordinates to place text), I copy (with a slight adaptation) an answer to another related question.

import matplotlib.pyplot as plt
fig, axes = plt.subplots(5, 2, sharex=True, sharey=True, figsize=(6,15))
# add a big axis, hide frame
fig.add_subplot(111, frameon=False)
# hide tick and tick label of the big axis
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.xlabel("common X")
plt.ylabel("common Y")

This results in the following (with matplotlib version 2.2.0):

This is one of the other method to solve the Error: "Cannot get a text value from a numeric cell “Poi”"

Go to the Excel Sheet. Drag and Select the Numerics which you are importing Data from the Excel sheet. Go to Format > Number > Then Select "Plain Text" Then Export as .xlsx. Now Try to Run the Script

Hope works Fine...!

Cannot get a text value from a numeric cell “Poi”.img

You don't need to store the column to reference it that way. Try this:

To set up:

CREATE TABLE tbl
  (zipcode text NOT NULL, city text NOT NULL, state text NOT NULL);
INSERT INTO tbl VALUES ('10954', 'Nanuet', 'NY');

We can see we have "the right stuff":

\pset border 2
SELECT * FROM tbl;

+---------+--------+-------+
| zipcode |  city  | state |
+---------+--------+-------+
| 10954   | Nanuet | NY    |
+---------+--------+-------+

Now add a function with the desired "column name" which takes the record type of the table as its only parameter:

CREATE FUNCTION combined(rec tbl)
  RETURNS text
  LANGUAGE SQL
AS $$
  SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;
$$;

This creates a function which can be used as if it were a column of the table, as long as the table name or alias is specified, like this:

SELECT *, tbl.combined FROM tbl;

Which displays like this:

+---------+--------+-------+--------------------+
| zipcode |  city  | state |      combined      |
+---------+--------+-------+--------------------+
| 10954   | Nanuet | NY    | 10954 - Nanuet, NY |
+---------+--------+-------+--------------------+

This works because PostgreSQL checks first for an actual column, but if one is not found, and the identifier is qualified with a relation name or alias, it looks for a function like the above, and runs it with the row as its argument, returning the result as if it were a column. You can even index on such a "generated column" if you want to do so.

Because you're not using extra space in each row for the duplicated data, or firing triggers on all inserts and updates, this can often be faster than the alternatives.

set confirm allows you to quit Vim gracefully with :q. You don't need to use ZZ or other heavy-handed mechanisms which blindly save or discard all changes.

Just follow these steps to transfer the apk onto the real device(with debugger key) and which is just for testing purpose. (Note: For proper distribution to the market you may need to sign your app with your keys and follow all the steps.)

1. Install your app onto the emulator.
2. Once it is installed goto DDMS, select the current running app under the devices window. This will then show all the files related to it under the file explorer.
3. Under file explorer go to data->app and select your APK (which is the package name of the app).
4. Select it and click on 'Pull a file from the device' button (the one with the save symbol).
5. This copies the APK to your system. From there you can copy the file to your real device, install and test it.

Good luck !

You can simulate a readonly select box using the CSS pointer-events property:

select[readonly]
{
    pointer-events: none;
}

The HTML tabindex property will also prevent it from being selected by keyboard tabbing:

<select tabindex="-1">

select[readonly]_x000D_
{_x000D_
    pointer-events: none;_x000D_
}_x000D_
_x000D_
_x000D_
/* irrelevent styling */_x000D_
_x000D_
*_x000D_
{_x000D_
  box-sizing: border-box;_x000D_
}_x000D_
_x000D_
*[readonly]_x000D_
{_x000D_
  background: #fafafa;_x000D_
  border: 1px solid #ccc;_x000D_
  color: #555;_x000D_
}_x000D_
_x000D_
input, select_x000D_
{_x000D_
  display:block;_x000D_
  width: 20rem;_x000D_
  padding: 0.5rem;_x000D_
  margin-bottom: 1rem;_x000D_
}

<form>_x000D_
  <input type="text" value="this is a normal text box">_x000D_
  <input type="text" readonly value="this is a readonly text box">_x000D_
  <select readonly tabindex="-1">_x000D_
    <option>This is a readonly select box</option>_x000D_
    <option>Option 2</option>_x000D_
  </select>_x000D_
  <select>_x000D_
    <option>This is a normal select box</option>_x000D_
    <option>Option 2</option>_x000D_
  </select>_x000D_
</form>

For SDK 29 :

String str1 = "";
folder1 = new File(String.valueOf(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES)));
if (folder1.exists()) {str1 = folder1.toString() + File.separator;}

public static void createTextFile(String sBody, String FileName, String Where) {
    try {
        File gpxfile = new File(Where, FileName);
        FileWriter writer = new FileWriter(gpxfile);
        writer.append(sBody);
        writer.flush();
        writer.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Then you can save your file like this :

createTextFile("This is Content","file.txt",str1);

Add the total row to your data collection that will be bound to the grid.

Sometimes the following fix will work. Go to your build.gradle of your project and add google() into the repositories element and google() should be the at the top of all the repository.

This is the sample of the repositories block. What you need to do is to add google() or if that exists already, take that to the top of all the line inside repositories

    repositories {
    google()
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
    maven { url "https://jitpack.io" }
    maven { url 'https://maven.google.com' }
}

Try This

SELECT Title  from #Movies
    SELECT CASE WHEN Title = '' THEN 'No Title' ELSE Title END AS Titile from #Movies

OR

SELECT [Id], [CategoryId], ISNULL(nullif(Title,''),'No data') as Title, [Director], [DateReleased] FROM #Movies

Restart the computer after has added new value to PATH.

Method 1: grep (may careful while value is expected to be a regex).

Try to avoid using grep, if looking at resources.

if ( grep( /^$value$/, @badparams ) ) {
  print "found";
}

Method 2: Linear Search

for (@badparams) {
    if ($_ eq $value) {
       print "found";
       last;
    }
}

Method 3: Use a hash

my %hash = map {$_ => 1} @badparams;
print "found" if (exists $hash{$value});

Method 4: smartmatch

(added in Perl 5.10, marked is experimental in Perl 5.18).

use experimental 'smartmatch';  # for perl 5.18
print "found" if ($value ~~ @badparams);

Method 5: Use the module List::MoreUtils

use List::MoreUtils qw(any);
@badparams = (1,2,3);
$value = 1;
print "found" if any {$_ == $value} @badparams;

Not sure if there is universally accepted standard but my own preferences are;

• constructors first
• static methods next, if there is a main method, always before other static methods
• non static methods next, usually in order of the significance of the method followed by any methods that it calls. This means that public methods that call other class methods appear towards the top and private methods that call no other methods usually end up towards the bottom
• standard methods like toString, equals and hashcode next
• getters and setters have a special place reserved right at the bottom of the class

If the default compiler chosen by cmake is gcc and you have installed clang, you can use the easy way to compile your project with clang:

$ mkdir build && cd build
$ CXX=clang++ CC=clang cmake ..
$ make -j2

data.removeAll(data); will do the work, I think.

pip3 install --upgrade setuptools WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.

How are you running the file? Is it from the command line or from an IDE? The directory that your executable is in is not necessarily your working directory.

Try using the full path name in the fopen and see if that fixes it. If so, then the problem is as described.

For example:

file = fopen("c:\\MyDirectory\\TestFile1.txt", "r");
file = fopen("/full/path/to/TestFile1.txt", "r");

Or open up a command window and navigate to the directory where your executable is, then run it manually.

As an aside, you can insert a simple (for Windows or Linux/UNIX/BSD/etc respectively):

system ("cd")
system("pwd")

before the fopen to show which directory you're actually in.

If you are using Apache, mod_rewrite is the easiest solution, and has a lot of documentation online how to do that. For example: http://www.askapache.com/htaccess/http-https-rewriterule-redirect.html

I'm just beginner to help you for getting edittext value to textview. Try out this code -

EditText edit = (EditText)findViewById(R.id.editext1);
TextView tview = (TextView)findViewById(R.id.textview1);
String result = edit.getText().toString();
tview.setText(result);

This will get the text which is in EditText Hope this helps you.

If you declare a pointer to a function like this:

int (*func)(int a, int b);

You can assign a place in memory to that function like this (requires libdl and dlopen)

#include <dlfcn.h>

int main(void)
{
    void *handle;
    char *func_name = "bla_bla_bla";
    handle = dlopen("foo.so", RTLD_LAZY);
    *(void **)(&func) = dlsym(handle, func_name);
    return func(1,2);
}

To load a local symbol using indirection, you can use dlopen on the calling binary (argv[0]).

The only requirement for this (other than dlopen(), libdl, and dlfcn.h) is knowing the arguments and type of the function.

checkout actual-branch

git merge {{commit-hash}}

If you don't care about animation, then you don't have to get the height of the element. At least in all the browsers I've tried, if you give scrollTop a number that's bigger than the maximum, it'll just scroll to the bottom. So give it the biggest number possible:

$(myScrollingElement).scrollTop(Number.MAX_SAFE_INTEGER);

If you want to scroll the page, rather than some element with a scrollbar, just make myScrollingElement equal to 'body, html'.

Since I need to do this in several places, I've written a quick and dirty jQuery function to make it more convenient, like this:

(function($) {
  $.fn.scrollToBottom = function() {
    return this.each(function (i, element) {
      $(element).scrollTop(Number.MAX_SAFE_INTEGER);
    });
  };
}(jQuery));

So I can do this when I append a buncho' stuff:

$(myScrollingElement).append(lotsOfHtml).scrollToBottom();

First off, I use nvm on linux machine.

When looking at the documentation for nvm at https://www.npmjs.org/package/nvm, it recommendations that you install nvm globally using the -g switch.

npm install -g nvm

Also there is a . in the path variable that they recommend.

export PATH=./node_modules/.bin:$PATH

so maybe your path should be

C:\Program Files (x86)\nodejs\node_modules\npm\\.bin

You have to rely on '#' but to make the task easier in vi you can perform the following (press escape first):

:10,20 s/^/#

with 10 and 20 being the start and end line numbers of the lines you want to comment out

and to undo when you are complete:

:10,20 s/^#//

It's go to newline then add spaces to start second line at end of first line

Output

Hello
     Goodbye

Yes you are right. You have placed WHERE clause wrong. You can only use one WHERE clause in single query so try AND for multiple conditions like this:

 SELECT table1.f_id  FROM table1 
   INNER JOIN table2
     ON table2.f_id = table1.f_id
 WHERE table2.f_type = 'InProcess'
   AND f_com_id = '430'
   AND f_status = 'Submitted' 

You need to define a single locale that you will use for the data stored in the database, the invariant culture is there for exactly this purpose.

When you display convert to the native type and then format for the user's culture.

E.g. to display:

string fromDb = "123.56";
string display = double.Parse(fromDb, CultureInfo.InvariantCulture).ToString(userCulture);

to store:

string fromUser = "132,56";
double value;
// Probably want to use a more specific NumberStyles selection here.
if (!double.TryParse(fromUser, NumberStyles.Any, userCulture, out value)) {
  // Error...
}
string forDB = value.ToString(CultureInfo.InvariantCulture);

PS. It, almost, goes without saying that using a column with a datatype that matches the data would be even better (but sometimes legacy applies).

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Judging from the examples you provide, I'm assuming that by ANNs, you mean multilayer feed-forward networks (FF nets for short), such as multilayer perceptrons, because those are in direct competition with SVMs.

One specific benefit that these models have over SVMs is that their size is fixed: they are parametric models, while SVMs are non-parametric. That is, in an ANN you have a bunch of hidden layers with sizes h₁ through h_n depending on the number of features, plus bias parameters, and those make up your model. By contrast, an SVM (at least a kernelized one) consists of a set of support vectors, selected from the training set, with a weight for each. In the worst case, the number of support vectors is exactly the number of training samples (though that mainly occurs with small training sets or in degenerate cases) and in general its model size scales linearly. In natural language processing, SVM classifiers with tens of thousands of support vectors, each having hundreds of thousands of features, is not unheard of.

Also, online training of FF nets is very simple compared to online SVM fitting, and predicting can be quite a bit faster.

EDIT: all of the above pertains to the general case of kernelized SVMs. Linear SVM are a special case in that they are parametric and allow online learning with simple algorithms such as stochastic gradient descent.

Your original rewrite should almost work. I'm not sure why it would be redirecting, but I think what you really want is just

rewrite ^ /base.html break;

You should be able to put that in a location or directly in the server.

import java.util.Base64;

.... Just making it clear that this answer uses the java.util.Base64 package, without using any third-party libraries.

String crntImage=<a valid base 64 string>

byte[] data = Base64.getDecoder().decode(crntImage);

try( OutputStream stream = new FileOutputStream("d:/temp/abc.pdf") ) 
{
   stream.write(data);
}
catch (Exception e) 
{
   System.err.println("Couldn't write to file...");
}

Use

num = num.toFixed(2);

Where 2 is the number of decimal places

Edit:

Here's the function to format number as you want

function formatNumber(number)
{
    number = number.toFixed(2) + '';
    x = number.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    return x1 + x2;
}

You can also use a spline. Feed in the values you have and interpolate points between your known points. Linking this with a least-squares fit, moving average or kalman filter (as mentioned in other answers) gives you the ability to calculate the points inbetween your "known" points.

Being able to interpolate the values between your knowns gives you a nice smooth transition and a /reasonable/ approximation of what data would be present if you had a higher-fidelity. http://en.wikipedia.org/wiki/Spline_interpolation

Different splines have different characteristics. The one's I've seen most commonly used are Akima and Cubic splines.

Another algorithm to consider is the Ramer-Douglas-Peucker line simplification algorithm, it is quite commonly used in the simplification of GPS data. (http://en.wikipedia.org/wiki/Ramer-Douglas-Peucker_algorithm)

I know it's a bit late, but I've tried everything above and nothing worked. The real problem was that I'm using hibernate, so it was trying to connect to mysql but was not able, thats why it showed time out.

Just to let u guys know, I'm using RDS(Amazon), so just to make a test I changed to my local mysql and it worked perfectly.

Hope that this answer helps somebody.

Thanks.

With the multiplication, I recommend using the modulo operator (%) to determine which numbers divide evenly into the target number like:

$factors = array();
for($i = 0; $i < $target; $i++){
    if($target % $i == 0){
        $temp = array()
        $a = $i;
        $b = $target / $i;
        $temp["a"] = $a;
        $temp["b"] = $b;
        $temp["index"] = $i;
        array_push($factors, $temp);
    }
}

This would leave you with an array of factors of the target number.

private void btnChoose2_Click(object sender, EventArgs e)
{
  OpenFileDialog openfileDialog1 = new OpenFileDialog();
  if (openfileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
  {
    this.btnChoose2.Text = openfileDialog1.FileName;
    String filename = DialogResult.ToString();

    var excelApp = new Excel.Application();
    excelApp.Visible = true;
    excelApp.Workbooks.Open(btnChoose2.Text);
  }
}

This is how I did it and it seems to work pretty well.

In you webpack.config.js file add the following:

devServer: {
    inline:true,
    port: 8008
  },

Obviously you can use any port that is not conflicting with another. I mention the conflict issue only because I spent about 4 hrs. fighting an issue only to discover that my services were running on the same port.

On your terminal, try running:

which -a ruby

This will output all the installed Ruby versions (via RVM, or otherwise) on your system in your PATH. If 1.8.7 is your system Ruby version, you can uninstall the system Ruby using:

sudo apt-get purge ruby

Once you have made sure you have Ruby installed via RVM alone, in your login shell you can type:

rvm --default use 2.0.0

You don't need to do this if you have only one Ruby version installed.

If you still face issues with any system Ruby files, try running:

dpkg-query -l '*ruby*'

This will output a bunch of Ruby-related files and packages which are, or were, installed on your system at the system level. Check the status of each to find if any of them is native and is causing issues.

It’s doing integer division. You can use to_f to force things into floating-point mode:

9.to_f / 5  #=> 1.8
9 / 5.to_f  #=> 1.8

This also works if your values are variables instead of literals. Converting one value to a float is sufficient to coerce the whole expression to floating point arithmetic.

You could also do this to make it more dynamic.

<input name="filterByPolarity" data-ng-model="text.polarity"/>

Then you ng-repeat will look like this

<div class="tweet" data-ng-repeat="tweet in tweets | filter:text"></div>

This filter will of course only be used to filter by polarity

I solved this by copying the branch data (with the errors) to my apple laptop local git folder.

Somehow in the terminal and when running: git status, tells me more specific data where the error occurs. If you look under the errors, hopefully you see a list of folders with error. In my case GIT showed the folder which was responsible for the error. Deleting that folder and commiting the branche, I succeeded. git status was working again the other devices updating by git pull; everything working again on every machine.

Hopefully this will work for you also.

You can use the cherry-pick to get the particular bug fix commit(s)

$ git checkout branch
$ git cherry-pick bugfix

Maybe Iterator’s remove() method? The JDK’s default collection classes should all creator iterators that support this method.

git rm --cached file will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

Kotlin

You can do it programmatically in Kotlin this way. You just ignore it if "supportActionBar" is null:

    supportActionBar?.setTitle(R.string.my_text)
    supportActionBar?.title = "My text"

Or this way. It throws an exception if "supportActionBar" is null.

    supportActionBar!!.setTitle(R.string.my_text)
    supportActionBar!!.title = "My text"

You can use the printf method, like so:

System.out.printf("%.2f", val);

In short, the %.2f syntax tells Java to return your variable (val) with 2 decimal places (.2) in decimal representation of a floating-point number (f) from the start of the format specifier (%).

There are other conversion characters you can use besides f:

• d: decimal integer
• o: octal integer
• e: floating-point in scientific notation

Simple, here replace the "APP" by name of the app you want to launch.

export APP_HOME=/Applications/APP.app/Contents/MacOS
export PATH=$PATH:$APP_HOME

Thanks me later.

Use a dynamic query. The front end is only to generate the required format:

DECLARE @invalue VARCHAR(100)
SELECT @invalue = '''Bishnu'',''Gautam'''

DECLARE @dynamicSQL VARCHAR(MAX)
SELECT @dynamicSQL = 'SELECT * FROM #temp WHERE [name] IN (' + @invalue + ')'
EXEC (@dynamicSQL)

Support iOS 13 and Below:

extension UIViewController {

    var topbarHeight: CGFloat {
        if #available(iOS 13.0, *) {
            return (view.window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0.0) +
                (self.navigationController?.navigationBar.frame.height ?? 0.0)
        } else {
            let topBarHeight = UIApplication.shared.statusBarFrame.size.height +
            (self.navigationController?.navigationBar.frame.height ?? 0.0)
            return topBarHeight
        }
    }
}

See this: Spring @PropertySource using YAML

I think the 3rd answer has what you're looking for, i.e have a separate POJO to map your yaml values into:

@ConfigurationProperties(path="classpath:/appprops.yml", name="db")
public class DbProperties {
    private String url;
    private String username;
    private String password;
...
}

Then annotate your test class with this:

@EnableConfigurationProperties(DbProperties.class)
public class PropertiesUsingService {

    @Autowired private DbProperties dbProperties;

}

I had this problem after upgrading to macOS Catalina.

The issue is resolved as follows:

1. Find git location from the terminal:

which git

2. Add the location of git in settings file with your location:

settings.json

"git.path": "/usr/local/bin/git",

Depending on your platform, the user settings file (settings.json) is located here:

Windows %APPDATA%\Code\User\settings.json

macOS $HOME/Library/Application Support/Code/User/settings.json

Linux $HOME/.config/Code/User/settings.json

What is the newline character in the C language: \r or \n?

The new-line may be thought of a some char and it has the value of '\n'. C11 5.2.1

This C new-line comes up in 3 places: C source code, as a single char and as an end-of-line in file I/O when in text mode.

1. Many compilers will treat source text as ASCII. In that case, codes 10, sometimes 13, and sometimes paired 13,10 as new-line for source code. Had the source code been in another character set, different codes may be used. This new-line typically marks the end of a line of source code (actually a bit more complicated here), // comment, and # directives.

2. In source code, the 2 characters \ and n represent the char new-line as \n. If ASCII is used, this char would have the value of 10.

3. In file I/O, in text mode, upon reading the bytes of the input file (and stdin), depending on the environment, when bytes with the value(s) of 10 (Unix), 13,10, (*1) (Windows), 13 (Old Mac??) and other variations are translated in to a '\n'. Upon writing a file (or stdout), the reverse translation occurs.
   Note: File I/O in binary mode makes no translation.

The '\r' in source code is the carriage return char.

(*1) A lone 13 and/or 10 may also translate into \n.

Like there was discussed above OS could kill the APPLICATION without any notification (there is no onDestroy event) so there is no way to save these global variables.

SharedPreferences could be a solution EXCEPT you have COMPLEX STRUCTURED variables (in my case I had integer array to store the IDs that the user has already handled). The problem with the SharedPreferences is that it is hard to store and retrieve these structures each time the values needed.

In my case I had a background SERVICE so I could move this variables to there and because the service has onDestroy event, I could save those values easily.

The split() method in javascript accepts two parameters: a separator and a limit. The separator specifies the character to use for splitting the string. If you don't specify a separator, the entire string is returned, non-separated. But, if you specify the empty string as a separator, the string is split between each character.

Therefore:

s.split('')

will have the effect you seek.

More information here

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

<h2 [ngStyle]="serverStatus == 'Offline'? {'color': 'red'{'color':'green'}">Server with ID: {{serverId}} is {{getServerStatus()}} </h2>

or you can also use something like this:

<h2 [ngStyle]="{backgroundColor: getColor()}">Server with ID: {{serverId}} is {{getServerStatus()}}</h2>

and in the *.ts

getColor(){return this.serverStatus === 'Offline' ? 'red' : 'green';}

Short circuit here means that the second condition won't be evaluated.

If ( A && B ) will result in short circuit if A is False.

If ( A && B ) will not result in short Circuit if A is True.

If ( A || B ) will result in short circuit if A is True.

If ( A || B ) will not result in short circuit if A is False.

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

When you have a lot of variables that don't need escaping, you can use an autoescape block:

{% autoescape off %}
{{ something }}
{{ something_else }}
<b>{{ something_important }}</b>
{% endautoescape %}

Here is a simple and more update format of getting the data:

   $now = new \DateTime('now');
   $month = $now->format('m');
   $year = $now->format('Y');

So i tried the above :javascript which works :) However HAML wraps the generated code in CDATA like so:

<script type="text/javascript">
  //<![CDATA[
    $(document).ready( function() {
       $('body').addClass( 'test' );
    } );
  //]]>
</script>

The following HAML will generate the typical tag for including (for example) typekit or google analytics code.

 %script{:type=>"text/javascript"}
  //your code goes here - dont forget the indent!

With native JavaScript:

newelement = element.cloneNode(bool)

where the Boolean indicates whether to clone child nodes or not.

Here is the complete documentation on MDN.

If you are specifying the output format manually you also need to make sure the args option is last in the list of output fields, otherwise it will be truncated.

Actually, that does not delete the variable/property. All it will do is set its value to None, therefore the variable will still take up space in memory. If you want to completely wipe all existence of the variable from memory, you can just type:

del self.left

In the first one Python has to execute one more operations than necessary(instead of just checking not equal to it has to check if it is not true that it is equal, thus one more operation). It would be impossible to tell the difference from one execution, but if run many times, the second would be more efficient. Overall I would use the second one, but mathematically they are the same

No, you should not need to. mod_rewrite is an Apache module. It has nothing to do with php.ini.

If the return in the try block is reached, it transfers control to the finally block, and the function eventually returns normally (not a throw).

If an exception occurs, but then the code reaches a return from the catch block, control is transferred to the finally block and the function eventually returns normally (not a throw).

In your example, you have a return in the finally, and so regardless of what happens, the function will return 34, because finally has the final (if you will) word.

Although not covered in your example, this would be true even if you didn't have the catch and if an exception were thrown in the try block and not caught. By doing a return from the finally block, you suppress the exception entirely. Consider:

public class FinallyReturn {
  public static final void main(String[] args) {
    System.out.println(foo(args));
  }

  private static int foo(String[] args) {
    try {
      int n = Integer.parseInt(args[0]);
      return n;
    }
    finally {
      return 42;
    }
  }
}

If you run that without supplying any arguments:

$ java FinallyReturn

...the code in foo throws an ArrayIndexOutOfBoundsException. But because the finally block does a return, that exception gets suppressed.

This is one reason why it's best to avoid using return in finally.

items in the first list where the Email does not exist in the second list.

from item1 in List1
where !(list2.Any(item2 => item2.Email == item1.Email))
select item1;

Jest has a method, toThrow(error), to test that a function throws when it is called.

So, in your case you should call it so:

expect(t).toThrowError(TypeError);

If you don't have the latest Homebrew: I "fixed" this in the past by forcing Homebrew to run as root, which could only be done by changing the ownership of the Homebrew executables to root. At some point, they removed this feature.

And I know they'll give lots of warnings saying it shouldn't run as root, but c'mon, it doesn't work properly otherwise.

You can use the following code snippet :

java -XX:+PrintFlagsFinal -Xms512m -Xmx1024m -Xss512k -XX:PermSize=64m -XX:MaxPermSize=128m
    -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

In my pc I am getting following output :

    uintx InitialHeapSize                          := 536870912       {product}
    uintx MaxHeapSize                              := 1073741824      {product}
    uintx PermSize                                 := 67108864        {pd product}
    uintx MaxPermSize                              := 134217728       {pd product}
     intx ThreadStackSize                          := 512             {pd product}

Given that IPV6 has a size of 1500, I would assert that carriers would not provide separate paths for IPV4 and IPV6 (they are both IP with different types), forcing them to equipment for ipv4 that would be old, redundant, more costly to maintain and less reliable. It wouldn't make any sense. Besides, doing so might easily be considered providing preferential treatment for some traffic -- a no no under rules they probably don't care much about (unless they get caught).

So 1472 should be safe for external use (though that doesn't mean an app like DNS that doesn't know about EDNS will accept it), and if you are talking internal nets, you can more likely know your network layout in which case jumbo packet sizes apply for for non-fragmented packets so for 4096 - 4068 bytes, and for intel's cards with 9014 byte buffers, a package size of ... wait...8086 bytes, would be the max...coincidence? snicker

****UPDATE****

Various answers give maximum values allowed by 1 SW vendor or various answers assuming encapsulation. The user didn't ask for the lowest value possible (like "0" for a safe UDP size), but the largest safe packet size.

Encapsulation values for various layers can be included multiple times. Since once you've encapsulated a stream -- there is nothing prohibiting, say, a VPN layer below that and a complete duplication of encapsulation layers above that.

Since the question was about maximum safe values, I'm assuming that they are talking about the maximum safe value for a UDP packet that can be received. Since no UDP packet is guaranteed, if you receive a UDP packet, the largest safe size would be 1 packet over IPv4 or 1472 bytes.

Note -- if you are using IPv6, the maximum size would be 1452 bytes, as IPv6's header size is 40 bytes vs. IPv4's 20 byte size (and either way, one must still allow 8 bytes for the UDP header).

I haven't used it yet but I would take a look at http://www.zoneminder.com/ The documentation explains you can install it on a modest machine with linux and use IP cameras for remote recording.

The problem with your code snippet is the way variables are expanded. Variable expansion is usually done when a statement is first read. In your case the whole FOR loop and its block is read and all variables, except the loop variables are expanded to their current value.

This means %c% in your echo %%i, %c% expanded instantly and so is actually used as echo %%i, 1 in each loop iteration.

So what you need is the delayed variable expansion. Find some good explanation about it here.

Variables that should be delay expanded are referenced with !VARIABLE! instead of %VARIABLE%. But you need to activate this feature with setlocal ENABLEDELAYEDEXPANSION and reset it with a matching endlocal.

Your modified code would look something like that:

set TEXT_T="myfile.txt"

set /a c=1

setlocal ENABLEDELAYEDEXPANSION

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
  set /a c=c+1

  echo %%i, !c!
)

endlocal

I don't think there's any way to get width of texts in variable-width fonts, especially in javascript.

The only way I can think is to make a hidden element that has variable width set by css, put text in its innerHTML, and get the width of that element. So you may be able to apply this method to cope with textarea auto-sizing problem.

xsi:nil is the correct way to represent a value such that: When the DOM Level 2 call getElementValue() is issued, the NULL value is returned. xsi:nil is also used to indicate a valid element with no content even if that elements content type normally doesn't allow empty elements.

If an empty tag is used, getElementValue() returns the empty string ("") If the tag is omitted, then no author tag is even present. This may be semantically different than setting it to 'nil' (Ex. Setting "Series" to nil may be that the book belongs to no series, while omitting series could mean that series is an inapplicable element to the current element.)

From: The W3C

XML Schema: Structures introduces a mechanism for signaling that an element should be accepted as ·valid· when it has no content despite a content type which does not require or even necessarily allow empty content. An element may be ·valid· without content if it has the attribute xsi:nil with the value true. An element so labeled must be empty, but can carry attributes if permitted by the corresponding complex type.

A clarification:
If you have a book xml element and one of the child elements is book:series you have several options when filling it out:

1. Removing the element entirely - This can be done when you wish to indicate that series does not apply to this book or that book is not part of a series. In this case xsl transforms (or other event based processors) that have a template that matches book:series will never be called. For example, if your xsl turns the book element into table row (xhtml:tr) you may get the incorrect number of table cells (xhtml:td) using this method.
2. Leaving the element empty - This could indicate that the series is "", or is unknown, or that the book is not part of a series. Any xsl transform (or other evernt based parser) that matches book:series will be called. The value of current() will be "". You will get the same number of xhtml:td tags using this method as with the next described one.
3. Using xsi:nil="true" - This signifies that the book:series element is NULL, not just empty. Your xsl transform (or other event based parser) that have a template matching book:series will be called. The value of current() will be empty (not empty string). The main difference between this method and (2) is that the schema type of book:series does not need to allow the empty string ("") as a valid value. This makes no real sense for a series element, but for a language element that is defined as an enumerated type in the schema, xsi:nil="true" allows the element to have no data. Another example would be elements of type decimal. If you want them to be empty you can union an enumerated string that only allows "" and a decimal, or use a decimal that is nillable.

Try replacing the string literal for date '1989-12-09' with TO_DATE('1989-12-09','YYYY-MM-DD')

Yes, you can. But if you have non-unique entries on your table, it will fail. Here is the how to add unique constraint on your table. If you're using PostgreSQL 9.x you can follow below instruction.

CREATE UNIQUE INDEX constraint_name ON table_name (columns);

You can easily restart your MySql service. This kicks the error off.

Here's a simple solution that doesn't require any hard-to-read LINQ or any prior sorting of the list.

   private static void CheckForDuplicateItems(List<string> items)
    {
        if (items == null ||
            items.Count == 0)
            return;

        for (int outerIndex = 0; outerIndex < items.Count; outerIndex++)
        {
            for (int innerIndex = 0; innerIndex < items.Count; innerIndex++)
            {
                if (innerIndex == outerIndex) continue;
                if (items[outerIndex].Equals(items[innerIndex]))
                {
                    // Duplicate Found
                }
            }
        }
    }

A Unix timestamp is simply the number of seconds since January the first 1970, so to add 24 hours to a Unix timestamp we just add the number of seconds in 24 hours. (24 * 60 *60)

time() + 24*60*60;

Passing the :value option to f.label will ensure the label tag's for attribute is the same as the id of the corresponding radio_button

<% form_for(@message) do |f| %>
  <%= f.radio_button :contactmethod, 'email' %> 
  <%= f.label :contactmethod, 'Email', :value => 'email' %>
  <%= f.radio_button :contactmethod, 'sms' %>
  <%= f.label :contactmethod, 'SMS', :value => 'sms' %>
<% end %>

See ActionView::Helpers::FormHelper#label

the :value option, which is designed to target labels for radio_button tags

A bit late, but this could also be useful. There is an IE filter, for IE 5.5+, which you can apply:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale');

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale')";

However, this scales the entire image to fit in the allocated area, so if you're using a sprite, this may cause issues.

Specification: AlphaImageLoader Filter @microsoft

Faster option:

The following code will copy your Pandas DF to postgres DB much faster than df.to_sql method and you won't need any intermediate csv file to store the df.

Create an engine based on your DB specifications.

Create a table in your postgres DB that has equal number of columns as the Dataframe (df).

Data in DF will get inserted in your postgres table.

from sqlalchemy import create_engine
import psycopg2 
import io

if you want to replace the table, we can replace it with normal to_sql method using headers from our df and then load the entire big time consuming df into DB.

engine = create_engine('postgresql+psycopg2://username:password@host:port/database')

df.head(0).to_sql('table_name', engine, if_exists='replace',index=False) #drops old table and creates new empty table

conn = engine.raw_connection()
cur = conn.cursor()
output = io.StringIO()
df.to_csv(output, sep='\t', header=False, index=False)
output.seek(0)
contents = output.getvalue()
cur.copy_from(output, 'table_name', null="") # null values become ''
conn.commit()

If you want both to reference the same variable, one of them should have int k;, and the other should have extern int k;

For this situation, you typically put the definition (int k;) in one .cpp file, and put the declaration (extern int k;) in a header, to be included wherever you need access to that variable.

If you want each k to be a separate variable that just happen to have the same name, you can either mark them as static, like: static int k; (in all files, or at least all but one file). Alternatively, you can us an anonymous namespace:

namespace { 
   int k;
};

Again, in all but at most one of the files.

In C, the compiler generally isn't quite so picky about this. Specifically, C has a concept of a "tentative definition", so if you have something like int k; twice (in either the same or separate source files) each will be treated as a tentative definition, and there won't be a conflict between them. This can be a bit confusing, however, because you still can't have two definitions that both include initializers--a definition with an initializer is always a full definition, not a tentative definition. In other words, int k = 1; appearing twice would be an error, but int k; in one place and int k = 1; in another would not. In this case, the int k; would be treated as a tentative definition and the int k = 1; as a definition (and both refer to the same variable).
