Programs & Examples On #No data

if you want to display a text view when the recycler view is empty you can do it like this :

ArrayList<SomeDataModel> arrayList = new ArrayList<>();

RecycleAdapter recycleAdapter =  new RecycleAdapter(getContext(),project_Ideas);

recyclerView..setAdapter(recycleAdapter);

if(arrayList.isEmpty())
{
    emptyTextView.setVisibility(View.VISIBLE);
    recyclerView.setVisibility(View.GONE);
}

I Assume you have TextView

and XML like this

 android:visibility="gone"

    
  

I have created customize function to validate given date is between two dates or not.

var getvalidDate = function(d){ return new Date(d) }

function validateDateBetweenTwoDates(fromDate,toDate,givenDate){
    return getvalidDate(givenDate) <= getvalidDate(toDate) && getvalidDate(givenDate) >= getvalidDate(fromDate);
}

Did you try this?

new File("<PATH OF YOUR FILE>").toURI().toString();

One problem is that easy_install is set up to download and install .egg files or source distributions (contained within .tgz, .tar, .tar.gz, .tar.bz2, or .zip files). It doesn't know how to deal with the PyWin32 extensions because they are put within a separate installer executable. You will need to download the appropriate PyWin32 installer file (for Python 2.7) and run it yourself. When you run easy_install again (provided you have it installed right, like in Sergio's instructions), you should see that your winpexpect package has been installed correctly.

Since it's Windows and open source we are talking about, it can often be a messy combination of install methods to get things working properly. However, easy_install is still better than hand-editing configuration files, for sure.

If you are returning a complex json object you need to modify you success function of your auto-complete as follows.

$.ajax({
    url: "/Employees/SearchEmployees",
    dataType: "json",
    data: {
        searchText: request.term
    },
    success: function (data) {
        response($.map(data.employees, function (item) {
            return {
                label: item.name,
                value: item.id
            };
        }));
    }
});

This depends not only on the operating system in question, but also on configuration, potentially real-time configuration.

For Linux:

cat /proc/sys/fs/file-max

will show the current maximum number of file descriptors total allowed to be opened simultaneously. Check out http://www.cs.uwaterloo.ca/~brecht/servers/openfiles.html

Different file name which posted as "recfile" at <input type="file" name='recfile' placeholder="Select file"/> and received as "file" at upload.single('file')

Solution : make sure both sent and received file are similar upload.single('recfile')

It says it all IsNullOrEmpty() does not include white spacing while IsNullOrWhiteSpace() does!

IsNullOrEmpty() If string is:
-Null
-Empty

IsNullOrWhiteSpace() If string is:
-Null
-Empty
-Contains White Spaces Only

This will return the string only if the condition is true.

public String myMethod()
{
    if(condition)
    {
       return x;
    }
    else
       return "";
}

Using regex and find&replace, you can delete all the lines containing #region without leaving empty lines. Because for some reason Ray's method didn't work on my machine I searched for (.*#region.*\n)|(\n.*#region.*) and left the replace box empty.

That regex ensures that the if #region is found on the first line, the ending newline is deleted, and if it is found on the last line the preceding newline is deleted.

Still, Ray's solution is the better one if it works for you.

A modern approach is to use ASP.NET Web API 2 (server-side) with jQuery Ajax (client-side).

Like page methods and ASMX web methods, Web API allows you to write C# code in ASP.NET which can be called from a browser or from anywhere, really!

Here is an example Web API controller, which exposes API methods allowing clients to retrieve details about 1 or all products (in the real world, products would likely be loaded from a database):

public class ProductsController : ApiController
{
    Product[] products = new Product[] 
    { 
        new Product { Id = 1, Name = "Tomato Soup", Category = "Groceries", Price = 1 }, 
        new Product { Id = 2, Name = "Yo-yo", Category = "Toys", Price = 3.75M }, 
        new Product { Id = 3, Name = "Hammer", Category = "Hardware", Price = 16.99M } 
    };

    [Route("api/products")]
    [HttpGet]
    public IEnumerable<Product> GetAllProducts()
    {
        return products;
    }

    [Route("api/product/{id}")]
    [HttpGet]
    public IHttpActionResult GetProduct(int id)
    {
        var product = products.FirstOrDefault((p) => p.Id == id);
        if (product == null)
        {
            return NotFound();
        }
        return Ok(product);
    }
}

The controller uses this example model class:

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public decimal Price { get; set; }
}

Example jQuery Ajax call to get and iterate over a list of products:

$(document).ready(function () {
    // Send an AJAX request
    $.getJSON("/api/products")
        .done(function (data) {
            // On success, 'data' contains a list of products.
            $.each(data, function (key, item) {
                // Add a list item for the product.
                $('<li>', { text: formatItem(item) }).appendTo($('#products'));
            });
        });
});

Not only does this allow you to easily create a modern Web API, you can if you need to get really professional and document it too, using ASP.NET Web API Help Pages and/or Swashbuckle.

Web API can be retro-fitted (added) to an existing ASP.NET Web Forms project. In that case you will need to add routing instructions into the Application_Start method in the file Global.asax:

RouteTable.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = System.Web.Http.RouteParameter.Optional }
);

Your additional threads must be initiated from the same app that is called by the WSGI server.

The example below creates a background thread that executes every 5 seconds and manipulates data structures that are also available to Flask routed functions.

import threading
import atexit
from flask import Flask

POOL_TIME = 5 #Seconds

# variables that are accessible from anywhere
commonDataStruct = {}
# lock to control access to variable
dataLock = threading.Lock()
# thread handler
yourThread = threading.Thread()

def create_app():
    app = Flask(__name__)

    def interrupt():
        global yourThread
        yourThread.cancel()

    def doStuff():
        global commonDataStruct
        global yourThread
        with dataLock:
        # Do your stuff with commonDataStruct Here

        # Set the next thread to happen
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()   

    def doStuffStart():
        # Do initialisation stuff here
        global yourThread
        # Create your thread
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()

    # Initiate
    doStuffStart()
    # When you kill Flask (SIGTERM), clear the trigger for the next thread
    atexit.register(interrupt)
    return app

app = create_app()          

Call it from Gunicorn with something like this:

gunicorn -b 0.0.0.0:5000 --log-config log.conf --pid=app.pid myfile:app

root = Tk()
root.geomentry('1599x1499')

Dll not found. Install Visual C++ 2015 redistributable to fix.

This is a simple solution that can be used when converting a string to a hex format:

private static String encryptPassword(String password) throws NoSuchAlgorithmException, UnsupportedEncodingException {

    MessageDigest crypt = MessageDigest.getInstance("SHA-1");
    crypt.reset();
    crypt.update(password.getBytes("UTF-8"));

    return new BigInteger(1, crypt.digest()).toString(16);
}

min(df['some_property'])
max(df['some_property'])

The built-in functions work well with Pandas Dataframes.

Use File.ReadAllText(path_to_file) to read

you can use concat([df1, df2, ...], axis=1) in order to concatenate two or more DFs aligned by indexes:

pd.concat([df1, df2, df3, ...], axis=1)

or merge for concatenating by custom fields / indexes:

# join by _common_ columns: `col1`, `col3`
pd.merge(df1, df2, on=['col1','col3'])

# join by: `df1.col1 == df2.index`
pd.merge(df1, df2, left_on='col1' right_index=True)

or join for joining by index:

 df1.join(df2)

Are you missing a using directive for System.Linq?

In Python, you don't do things that way. When people do that in languages like Java, they generally want a default value (if they don't, they generally want a method with a different name). So, in Python, you can have default values.

class A(object):  # Remember the ``object`` bit when working in Python 2.x

    def stackoverflow(self, i=None):
        if i is None:
            print 'first form'
        else:
            print 'second form'

As you can see, you can use this to trigger separate behaviour rather than merely having a default value.

>>> ob = A()
>>> ob.stackoverflow()
first form
>>> ob.stackoverflow(2)
second form

you can use linq :) using :

System.linq;
var newList = people.OrderBy(x=>x.Name).ToList();

I just need one line to show a website in my app:

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://match4app.com")));

If some other portion of your layout is influencing the div width you can set width:auto and the div (which is a block element) will fill the space

<div style="width:auto">
    <div style="margin-left:45px;width:auto">
        <asp:TextBox ID="txtTitle" runat="server" Width="100%"></asp:TextBox><br />
    </div>
</div>

If that's still not working we may need to see more of your layout HTML/CSS

I realize this is an old post but I find myself coming back to this thread a lot as it is one of the top search results when searching for this topic. However, I always leave more confused then when I came due to the conflicting information. Ultimately I always have to perform my own tests to figure it out. So this time I will post my findings.

TL;DR Most people will want to use Exit to terminate a running scripts. However, if your script is merely declaring functions to later be used in a shell, then you will want to use Return in the definitions of said functions.

Exit vs Return vs Break

• Exit: This will "exit" the currently running context. If you call this command from a script it will exit the script. If you call this command from the shell it will exit the shell.

  If a function calls the Exit command it will exit what ever context it is running in. So if that function is only called from within a running script it will exit that script. However, if your script merely declares the function so that it can be used from the current shell and you run that function from the shell, it will exit the shell because the shell is the context in which the function contianing the Exit command is running.

  Note: By default if you right click on a script to run it in PowerShell, once the script is done running, PowerShell will close automatically. This has nothing to do with the Exit command or anything else in your script. It is just a default PowerShell behavior for scripts being ran using this specific method of running a script. The same is true for batch files and the Command Line window.

• Return: This will return to the previous call point. If you call this command from a script (outside any functions) it will return to the shell. If you call this command from the shell it will return to the shell (which is the previous call point for a single command ran from the shell). If you call this command from a function it will return to where ever the function was called from.

  Execution of any commands after the call point that it is returned to will continue from that point. If a script is called from the shell and it contains the Return command outside any functions then when it returns to the shell there are no more commands to run thus making a Return used in this way essentially the same as Exit.

• Break: This will break out of loops and switch cases. If you call this command while not in a loop or switch case it will break out of the script. If you call Break inside a loop that is nested inside a loop it will only break out of the loop it was called in.

  There is also an interesting feature of Break where you can prefix a loop with a label and then you can break out of that labeled loop even if the Break command is called within several nested groups within that labeled loop.

  While ($true) {
      # Code here will run
  
      :myLabel While ($true) {
          # Code here will run
  
          While ($true) {
              # Code here will run
  
              While ($true) {
                  # Code here will run
                  Break myLabel
                  # Code here will not run
              }
  
              # Code here will not run
          }
  
          # Code here will not run
      }
  
      # Code here will run
  }
  

I just wanted to provide the most comprehensible solution, the anti code-golf version.

from itertools import combinations

l = ["x", "y", "z", ]

def powerset(items):
    combo = []
    for r in range(len(items) + 1):
        #use a list to coerce a actual list from the combinations generator
        combo.append(list(combinations(items,r)))
    return combo

l_powerset = powerset(l)

for i, item in enumerate(l_powerset):
    print "All sets of length ", i
    print item

The results

All sets of length 0

[()]

All sets of length 1

[('x',), ('y',), ('z',)]

All sets of length 2

[('x', 'y'), ('x', 'z'), ('y', 'z')]

All sets of length 3

[('x', 'y', 'z')]

For more see the itertools docs, also the wikipedia entry on power sets

Here is another cool way to do it- using en external viewer that accepts command line switches (IrfanView in this case) : * I based the loop on what Michal Krzych has written above.

Sub ExportPicturesToFiles()
    Const saveSceenshotTo As String = "C:\temp\"
    Const pictureFormat As String = ".jpg"

    Dim pic As Shape
    Dim sFileName As String
    Dim i As Long

    i = 1

    For Each pic In ActiveSheet.Shapes
        pic.Copy
        sFileName = saveSceenshotTo & Range("A" & i).Text & pictureFormat

        Call ExportPicWithIfran(sFileName)

        i = i + 1
    Next
End Sub

Public Sub ExportPicWithIfran(sSaveAsPath As String)
    Const sIfranPath As String = "C:\Program Files\IrfanView\i_view32.exe"
    Dim sRunIfran As String

    sRunIfran = sIfranPath & " /clippaste /convert=" & _
                            sSaveAsPath & " /killmesoftly"

    ' Shell is no good here. If you have more than 1 pic, it will
    ' mess things up (pics will over run other pics, becuase Shell does
    ' not make vba wait for the script to finish).
    ' Shell sRunIfran, vbHide

    ' Correct way (it will now wait for the batch to finish):
    call MyShell(sRunIfran )
End Sub

Edit:

  Private Sub MyShell(strShell As String)
  ' based on:
    ' http://stackoverflow.com/questions/15951837/excel-vba-wait-for-shell-command-to-complete
   ' by Nate Hekman

    Dim wsh As Object
    Dim waitOnReturn As Boolean:
    Dim windowStyle As VbAppWinStyle

    Set wsh = VBA.CreateObject("WScript.Shell")
    waitOnReturn = True
    windowStyle = vbHide

    wsh.Run strShell, windowStyle, waitOnReturn
End Sub

Personally, I use something close from fubo's solution and it works well:

image.ScaleToFit(document.PageSize);
image.SetAbsolutePosition(0,0);

I missed the obvious answer using hex numbers for the fromRGB constructor:

Color.fromRGBO(0xb7, 0x40, 0x93, 1),

SSH itself provides a means of communication, it does not know anything about directories. Since you can specify which remote command to execute (this is - by default - your shell), I'd start there.

For the sake of completeness, what you are trying to create is a "modal window".

Numerous JS solutions allow you to create them with ease, take the time to find the one which best suits your needs.

I have used Tinybox 2 for small projects : http://sandbox.scriptiny.com/tinybox2/

I too got similar error when i misplaced the code

text=(TextView)findViewById(R.id.text);// this line has to be below setcontentview
setContentView(R.layout.activity_my_otype);
//this is the correct place
text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            }
    });

I got it working on placing the code in right order as shown below

setContentView(R.layout.activity_my_otype);
text=(TextView)findViewById(R.id.text);
 text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            }
    });

QUICK FIX (not the best)

Change the import react-native header lines:

 #import <React/RCTBridgeModule.h>
 #import <React/RCTLog.h>

To:

 #import "RCTBridgeModule.h"
 #import "RCTLog.h"

Here is an example of changes I had to make for the library I was trying to use: Closes #46 - 'RCTBridgeModule.h' file not found.

Your code as given (after the edit) compiles fine, so something else is wrong that isn't in what you posted.

Some things to check, is everything public? That includes both the class and the method.

Overload with different parameters?

Are you sure that Base is the class you think it is? I.e. is there another class by the same name that it's actually referencing?

Edit:

To answer the question in your comment, you can't override a method with different parameters, nor is there a need to. You can create a new method (with the new parameter) without the override keyword and it will work just fine.

If your intention is to prohibit calling of the base method without the parameter you can mark the method as protected instead of public. That way it can only be called from classes that inherit from Base

The right answer is:

android {
    ....
    ....

    sourceSets {
        main.java.srcDirs += 'src/main/<YOUR DIRECTORY>'
    }
}

Furthermore, if your external source directory is not under src/main, you could use a relative path like this:

sourceSets {
    main.java.srcDirs += 'src/main/../../../<YOUR DIRECTORY>'
}

Use <div contenteditable="true"> (supported well) with storing to <input type="hidden">.

HTML:

<div id="multilineinput" contenteditable="true"></div>
<input type="hidden" id="detailsfield" name="detailsfield">

js (using jQuery)

$("#multilineinput").on('keyup',function(e) {   
    $("#detailsfield").val($(this).text()); //store content to input[type=hidden]
});
//optional - one line but wrap it
$("#multilineinput").on('keypress',function(e) {    
    if(e.which == 13) { //on enter
        e.preventDefault(); //disallow newlines     
        // here comes your code to submit
    }
});

GitHub is the entire site. Gists are a particular service offered on that site, namely code snippets akin to pastebin. However, everything is driven by git revision control, so gists also have complete revision histories.

I use django 1.7+ and python 2.7+, the solution above dose not work. And the input value in the form can be got use POST as below (use the same form above):

if form.is_valid():
  data = request.POST.get('my_form_field_name')
  print data

Hope this helps.

UPDATED: As of angularjs 1.5, promise methods success and error have been deprecated. (see this answer)

from current docs:

$http.get('/someUrl', config).then(successCallback, errorCallback);
$http.post('/someUrl', data, config).then(successCallback, errorCallback);

you can use the function's other arguments like so:

error(function(data, status, headers, config) {
    console.log(data);
    console.log(status);
}

see $http docs:

// Simple GET request example :
$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

$("#t").text($("#cb").find(":checked").val())

The following may help give you want you need:

SELECT
    index_owner, index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
ORDER BY
    index_owner, 
    table_name,
    index_name,
    column_position
    ;

For my use case, I wanted the column_names and order that they are in the indices (so that I could recreate them in a different database engine after migrating to AWS). The following was what I used, in case it is of use to anyone else:

SELECT
    index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
WHERE
    INDEX_OWNER = 'FOO'
    AND TABLE_NAME NOT LIKE '%$%'
ORDER BY
    table_name,
    index_name,
    column_position
    ;

The native option is missing so I'll add it for the next guy/gall that looks for it.

Starting on Django 1.7.x there is a built-in DjangoJSONEncoder that you can get it from django.core.serializers.json.

import json
from django.core.serializers.json import DjangoJSONEncoder
from django.forms.models import model_to_dict

model_instance = YourModel.object.first()
model_dict = model_to_dict(model_instance)

json.dumps(model_dict, cls=DjangoJSONEncoder)

Presto!

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

Is it possible to select elements in CSS by their HTML5 data attributes? This can easily be answered just by trying it, and the answer is, of course, yes. But this invariably leads us to the next question, 'Should we select elements in CSS by their HTML5 data attributes?' There are conflicting opinions on this.

In the 'no' camp is (or at least was, back in 2014) CSS legend Harry Roberts. In the article, Naming UI components in OOCSS, he wrote:

It’s important to note that although we can style HTML via its data-* attributes, we probably shouldn’t. data-* attributes are meant for holding data in markup, not for selecting on. This, from the HTML Living Standard (emphasis mine):

"Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements."

The W3C spec was frustratingly vague on this point, but based purely on what it did and didn't say, I think Harry's conclusion was perfectly reasonable.

Since then, plenty of articles have suggested that it's perfectly appropriate to use custom data attributes as styling hooks, including MDN's guide, Using data attributes. There's even a CSS methodology called CUBE CSS which has adopted the data attribute hook as the preferred way of adding styles to component 'exceptions' (known as modifiers in BEM).

Thankfully, the WHATWG HTML Living Standard has since added a few more words and even some examples (emphasis mine):

Custom data attributes are intended to store custom data, state, annotations, and similar, private to the page or application, for which there are no more appropriate attributes or elements.

In this example, custom data attributes are used to store the result of a feature detection for PaymentRequest, which could be used in CSS to style a checkout page differently.

Authors should carefully design such extensions so that when the attributes are ignored and any associated CSS dropped, the page is still usable.

TL;DR: Yes, it's okay to use data-* attributes in CSS selectors, provided the page is still usable without them.

There is nothing particularly tricky about the example you posted.

In a ternary operator, the first argument (the conditional) is evaluated and if the result is true, the second argument is evaluated and returned, otherwise, the third is evaluated and returned. Each of those arguments can be any valid code block, including function calls.

Think of it this way:

var x = (1 < 2) ? true : false;

Could also be written as:

var x = (1 < 2) ? getTrueValue() : getFalseValue();

This is perfectly valid, and those functions can contain any arbitrary code, whether it is related to returning a value or not. Additionally, the results of the ternary operation don't have to be assigned to anything, just as function results do not have to be assigned to anything:

(1 < 2) ? getTrueValue() : getFalseValue();

Now simply replace those with any arbitrary functions, and you are left with something like your example:

(1 < 2) ? removeItem($this) : addItem($this);

Now your last example really doesn't need a ternary at all, as it can be written like this:

x = (1 < 2);  // x will be set to "true"

... you can use it on any granularity type i.e.:

DATEPART(YEAR, [date])

DATEPART(MONTH, [date]) 

DATEPART(DAY, [date])    

DATEPART(HOUR, [date]) 

DATEPART(MINUTE, [date])

(note: I like the [ ] around the date reserved word though. Of course that's in case your column with timestamp is labeled "date")

I generally prefer to add these codes in a function to get the Android version:

int whichAndroidVersion;

whichAndroidVersion= Build.VERSION.SDK_INT;
textView.setText("" + whichAndroidVersion); //If you don't use "" then app crashes.

For example, that code above will set the text into my textView as "29" now.

I just wanted to add my opinion about this.

I think we can just use like this:

var haystack = 'hello world';
var needle = 'he';

if (haystack.indexOf(needle) == 0) {
  // Code if string starts with this substring
}

Here is my solution to split a file called patch6.txt (about 32,000 lines) into separate files of 1000 lines each. Its not quick, but it does the job.

$infile = "D:\Malcolm\Test\patch6.txt"
$path = "D:\Malcolm\Test\"
$lineCount = 1
$fileCount = 1

You should check out the new Eclipse 2019-09 4.13 Quick Search feature

The new Quick Search dialog provides a convenient, simple and fast way to run a textual search across your workspace and jump to matches in your code.

The dialog provides a quick overview showing matching lines of text at a glance.
It updates as quickly as you can type and allows for quick navigation using only the keyboard.

A typical workflow starts by pressing the keyboard shortcut Ctrl+Alt+Shift+L
(or Cmd+Alt+Shift+L on Mac).
Typing a few letters updates the search result as you type.
Use Up-Down arrow keys to select a match, then hit Enter to open it in an editor.

What is wrong with List.Find ??

I think we need more information on what you've done, and why it fails, before we can provide truly helpful answers.

Use ngStorage For All Your AngularJS Local Storage Needs. Please note that this is NOT a native part of the Angular JS framework.

ngStorage contains two services, $localStorage and $sessionStorage

angular.module('app', [
   'ngStorage'
]).controller('Ctrl', function(
    $scope,
    $localStorage,
    $sessionStorage
){});

Check the Demo

Simply point the new repo by changing the GIT repo URL with this command:

git remote set-url origin [new repo URL]

Example: git remote set-url origin [email protected]:Batman/batmanRepoName.git

Now, pushing and pulling are linked to the new REPO.

Then push normally like so:

git push -u origin master

Write command: adb devices (it will list the device currently connected) Select Textbox where you want to write text. Write command: adb shell input text "Yourtext" (make sure only one device is connected to run this command) Done!

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

You can use the following code to check if it's a leap year:

ily = function(yr) {
    return (yr % 400) ? ((yr % 100) ? ((yr % 4) ? false : true) : false) : true;
}

this does not directly answer your question (for which Naputipulu Jon and PriceHardman have fantastic replies)

However, for the purpose of a few classification tasks etc. you could use

pandas.get_dummies(input_df) 

this can input dataframe with categorical data and return a dataframe with binary values. variable values are encoded into column names in the resulting dataframe. more

The accepted answer definitely works, but somehow miss an important point.

The OP is asking for a dictionary sorted by it's keys this is just not really possible and not what OrderedDict is doing.

OrderedDict is maintaining the content of the dictionary in insertion order. First item inserted, second item inserted, etc.

>>> d = OrderedDict()
>>> d['foo'] = 1
>>> d['bar'] = 2
>>> d
OrderedDict([('foo', 1), ('bar', 2)])

>>> d = OrderedDict()
>>> d['bar'] = 2
>>> d['foo'] = 1
>>> d
OrderedDict([('bar', 2), ('foo', 1)])

Hencefore I won't really be able to sort the dictionary inplace, but merely to create a new dictionary where insertion order match key order. This is explicit in the accepted answer where the new dictionary is b.

This may be important if you are keeping access to dictionaries through containers. This is also important if you itend to change the dictionary later by adding or removing items: they won't be inserted in key order but at the end of dictionary.

>>> d = OrderedDict({'foo': 5, 'bar': 8})
>>> d
OrderedDict([('foo', 5), ('bar', 8)])
>>> d['alpha'] = 2
>>> d
OrderedDict([('foo', 5), ('bar', 8), ('alpha', 2)])

Now, what does mean having a dictionary sorted by it's keys ? That makes no difference when accessing elements by keys, this only matter when you are iterating over items. Making that a property of the dictionary itself seems like overkill. In many cases it's enough to sort keys() when iterating.

That means that it's equivalent to do:

>>> d = {'foo': 5, 'bar': 8}
>>> for k,v in d.iteritems(): print k, v

on an hypothetical sorted by key dictionary or:

>>> d = {'foo': 5, 'bar': 8}
>>> for k, v in iter((k, d[k]) for k in sorted(d.keys())): print k, v

Of course it is not hard to wrap that behavior in an object by overloading iterators and maintaining a sorted keys list. But it is likely overkill.

i recommand to use BAT to EXE converter for your desires

It's a long pointer to a constant, wide string (i.e. a string of wide characters).

Since it's a wide string, you want to make your constant look like: L"TestWindow". I wouldn't create the intermediate a either, I'd just pass L"TestWindow" for the parameter:

ghTest = FindWindowEx(NULL, NULL, NULL, L"TestWindow");

If you want to be pedantically correct, an "LPCTSTR" is a "text" string -- a wide string in a Unicode build and a narrow string in an ANSI build, so you should use the appropriate macro:

ghTest = FindWindow(NULL, NULL, NULL, _T("TestWindow"));

Few people care about producing code that can compile for both Unicode and ANSI character sets though, and if you don't getting it to really work correctly can be quite a bit of extra work for little gain. In this particular case, there's not much extra work, but if you're manipulating strings, there's a whole set of string manipulation macros that resolve to the correct functions.

On MAC

Step 1: Alt + Cmd + F . At the bottom, a window appears Step 2: Enable Regular Expression. Left side on the window, looks like .* Step 3: Enter text to you want to find in the Find input field Step 4: Enter replace text in the Replace input field Step 5: Click on Replace All - Right bottom.

I would use specific user (and NOT Application user). Then I will enable impersonation in the application. Once you do that whatever account is set as the specific user, those credentials would used to access local resources on that server (Not for external resources).

Specific User setting is specifically meant for accessing local resources.

Check following to help the understand the concept of CTE recursion

DECLARE
@startDate DATETIME,
@endDate DATETIME

SET @startDate = '11/10/2011'
SET @endDate = '03/25/2012'

; WITH CTE AS (
    SELECT
        YEAR(@startDate) AS 'yr',
        MONTH(@startDate) AS 'mm',
        DATENAME(mm, @startDate) AS 'mon',
        DATEPART(d,@startDate) AS 'dd',
        @startDate 'new_date'
    UNION ALL
    SELECT
        YEAR(new_date) AS 'yr',

Actually the @Ian Robinson answer works well but Chrome will continue complain with that message : "Resource interpreted as Font but transferred with MIME type application/x-woff"

If you get that, you can change from

application/x-woff

to

application/x-font-woff

and you will not have any Chrome console errors anymore !

(tested on Chrome 17)

I would create a structure and pass that as void* to pthread_create

struct threadArg {
    int intData;
    long longData;
    etc...
};


threadArg thrArg;
thrArg.intData = 4;
...
pthread_create(&thread, NULL, myFcn, (void*)(threadArg*)&thrArg);


void* myFcn(void* arg)
{
    threadArg* pThrArg = (threadArg*)arg;
    int computeSomething = pThrArg->intData;
    ...
}

Keep in mind that thrArg should exist till the myFcn() uses it.

Ensure you have an index on your firstname and lastname columns and go with 1. This really won't have much of a performance impact at all.

EDIT: After @Dems comment regarding spamming the plan cache ,a better solution might be to create a computed column on the existing table (or a separate view) which contained a concatenated Firstname + Lastname value, thus allowing you to execute a query such as

SELECT City 
FROM User 
WHERE Fullname in (@fullnames)

where @fullnames looks a bit like "'JonDoe', 'JaneDoe'" etc

function image()
{
    //dynamically add an image and set its attribute
    var img=document.createElement("img");
    img.src="p1.jpg"
    img.id="picture"
    var foo = document.getElementById("fooBar");
    foo.appendChild(img);
}

<span id="fooBar">&nbsp;</span>

For functions that do not have more than 2 parameters, you can pass them without defining your own interface. For example,

class Klass {
  static List<String> foo(Integer a, String b) { ... }
}

class MyClass{

  static List<String> method(BiFunction<Integer, String, List<String>> fn){
    return fn.apply(5, "FooBar");
  }
}

List<String> lStr = MyClass.method((a, b) -> Klass.foo((Integer) a, (String) b));

In BiFunction<Integer, String, List<String>>, Integer and String are its parameters, and List<String> is its return type.

For a function with only one parameter, you can use Function<T, R>, where T is its parameter type, and R is its return value type. Refer to this page for all the interfaces that are already made available by Java.

Almost everything in EC2 is multi-tenant. What the network performance indicates is what priority you will have compared with other instances sharing the same infrastructure.

If you need a guaranteed level of bandwidth, then EC2 will likely not work well for you.

You can only type them manually, but the content assist helps you there, so it is pretty easy.

Add this line

<uses-permission android:name="android.permission."/> 

and hit ctrl + space after the dot (or cmd + space on Mac). If you need an explanation for the permission, you can hit ctrl + q.

As a pure CSS solution for the close or 'times' symbol you can use the ISO code with the content property. I often use this for :after or :before pseudo selectors.

The content code is \00d7.

Example

div:after{
  display: inline-block;
  content: "\00d7"; /* This will render the 'X' */
}

You can then style and position the pseudo selector in any way you want. Hope this helps someone :).

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

This is not directly related to the initial issue, but probably will help somebody.

I faced same issue when was trying to send similar request using domain account. So mine issue was in not escaped character in login name.

Bad example:

'ABC\username'

Good example:

'ABC\\username'

While awk's printf can be used, you may want to look into pr or (on BSDish systems) rs for formatting.

Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express (%PROGRAMFILES(x86)%\IIS Express on x64 architectures) and its called iisexpress.exe.

To see all the possible command-line options, just run:

iisexpress /?

and the program detailed help will show up.

If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.

There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config): the /site and /siteId.

With the first one, you can launch a specific site by name:

iisexpress /site:SiteName

And with the latter, you can launch by specifying the ID:

iisexpress /siteId:SiteId

With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.

Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):

iisexpress /path:FullSitePath

This covers the basic IISExpress usage from the command line.

You can use the following commands to delete. Use the "match all docs" query in a delete by query command:

'<delete><query>*:*</query></delete>

You must also commit after running the delete so, to empty the index, run the following two commands:

curl http://localhost:8983/solr/update --data '<delete><query>*:*</query></delete>' -H 'Content-type:text/xml; charset=utf-8'
curl http://localhost:8983/solr/update --data '<commit/>' -H 'Content-type:text/xml; charset=utf-8'

Another strategy would be to add two bookmarks in your browser:

http://localhost:8983/solr/update?stream.body=<delete><query>*:*</query></delete>
http://localhost:8983/solr/update?stream.body=<commit/>

If you're using jQuery you might want to check out jQuery.param() http://api.jquery.com/jQuery.param/

Example:

var params = {
    parameter1: 'value1',
    parameter2: 'value2',
    parameter3: 'value3' 
};
?var query = $.param(params);
document.write(query);

You can’t run arbitrary Python code in jinja; it doesn’t work like JSP in that regard (it just looks similar). All the things in jinja are custom syntax.

For your purpose, it would make most sense to define a custom filter, so you could for example do the following:

The grass is {{ variable1 | splitpart(0, ',') }} and the boat is {{  splitpart(1, ',') }}
Or just:
The grass is {{ variable1 | splitpart(0) }} and the boat is {{  splitpart(1) }}

The filter function could then look like this:

def splitpart (value, index, char = ','):
    return value.split(char)[index]

An alternative, which might make even more sense, would be to split it in the controller and pass the splitted list to the view.

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

A simple solution is to assign color for each class. This way, we can control how each color is for each class. For example:

arr1 = [1, 2, 3, 4, 5]
arr2 = [2, 3, 3, 4, 4]
labl = [0, 1, 1, 0, 0]
color= ['red' if l == 0 else 'green' for l in labl]
plt.scatter(arr1, arr2, color=color)

use window.open("file2.html"); to open on new window,

or use window.location.href = "file2.html" to open on same window.

Android Market requires you to sign all apps you publish with a certificate, using a public/private key mechanism (the certificate is signed with your private key). This provides a layer of security that prevents, among other things, remote attackers from pushing malicious updates to your application to market (all updates must be signed with the same key).

From The App-Signing Guide of the Android Developer's site:

In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications. There are several reasons why you should do so...

Using the same key has a few benefits - One is that it's easier to share data between applications signed with the same key. Another is that it allows multiple apps signed with the same key to run in the same process, so a developer can build more "modular" applications.

According to oracle online documentation

ORA-12541: TNS:no listener

Cause: The connection request could not be completed because the listener is not running.

Action: Ensure that the supplied destination address matches one of the addresses used by 
the listener - compare the TNSNAMES.ORA entry with the appropriate LISTENER.ORA file (or  
TNSNAV.ORA if the connection is to go by way of an Interchange). Start the listener on 
the remote machine.

Try using the property ForeColor. Like this :

TextBox1.ForeColor = Color.Red;

you can get all direct of files in your root directory by using std::experimental:: filesystem::directory_iterator(). Then, read the name of these pathfiles.

#include <iostream>
#include <filesystem>
#include <string>
#include <direct.h>
using namespace std;
namespace fs = std::experimental::filesystem;
void ShowListFile(string path)
{
for(auto &p: fs::directory_iterator(path))  /*get directory */
     cout<<p.path().filename()<<endl;   // get file name
}

int main() {

ShowListFile("C:/Users/dell/Pictures/Camera Roll/");
getchar();
return 0;
}

Yes, it can be done as long as both windows are on the same domain. The window.open() function will return a handle to the new window. The child window can access the parent window using the DOM element "opener".

You can also pass your desired encoding to the String constructor as a Charset constant from StandardCharsets. This may be safer than passing the encoding as a String, as suggested in the other answers.

For example, for UTF-8 encoding

String bytesAsString = new String(bytes, StandardCharsets.UTF_8);

Here is a copy of an answer I made of some duplicate question since then deleted about Git vs. SVN (September 2009).

Better? Aside from the usual link WhyGitIsBetterThanX, they are different:

one is a Central VCS based on cheap copy for branches and tags the other (Git) is a distributed VCS based on a graph of revisions. See also Core concepts of VCS.

That first part generated some mis-informed comments pretending that the fundamental purpose of the two programs (SVN and Git) is the same, but that they have been implemented quite differently.
To clarify the fundamental difference between SVN and Git, let me rephrase:

• SVN is the third implementation of a revision control: RCS, then CVS and finally SVN manage directories of versioned data. SVN offers VCS features (labeling and merging), but its tag is just a directory copy (like a branch, except you are not "supposed" to touch anything in a tag directory), and its merge is still complicated, currently based on meta-data added to remember what has already been merged.

• Git is a file content management (a tool made to merge files), evolved into a true Version Control System, based on a DAG (Directed Acyclic Graph) of commits, where branches are part of the history of datas (and not a data itself), and where tags are a true meta-data.

To say they are not "fundamentally" different because you can achieve the same thing, resolve the same problem, is... plain false on so many levels.

• if you have many complex merges, doing them with SVN will be longer and more error prone. if you have to create many branches, you will need to manage them and merge them, again much more easily with Git than with SVN, especially if a high number of files are involved (the speed then becomes important)
• if you have partial merges for a work in progress, you will take advantage of the Git staging area (index) to commit only what you need, stash the rest, and move on on another branch.
• if you need offline development... well with Git you are always "online", with your own local repository, whatever the workflow you want to follow with other repositories.

Still the comments on that old (deleted) answer insisted:

VonC: You are confusing fundamental difference in implementation (the differences are very fundamental, we both clearly agree on this) with difference in purpose.
They are both tools used for the same purpose: this is why many teams who've formerly used SVN have quite successfully been able to dump it in favor of Git.
If they didn't solve the same problem, this substitutability wouldn't exist.

, to which I replied:

"substitutability"... interesting term (used in computer programming).
Off course, Git is hardly a subtype of SVN.

You may achieve the same technical features (tag, branch, merge) with both, but Git does not get in your way and allow you to focus on the content of the files, without thinking about the tool itself.

You certainly cannot (always) just replace SVN by Git "without altering any of the desirable properties of that program (correctness, task performed, ...)" (which is a reference to the aforementioned substitutability definition):

• One is an extended revision tool, the other a true version control system.
• One is suited small to medium monolithic project with simple merge workflow and (not too much) parallel versions. SVN is enough for that purpose, and you may not need all the Git features.
• The other allows for medium to large projects based on multiple components (one repo per component), with large number of files to merges between multiple branches in a complex merge workflow, parallel versions in branches, retrofit merges, and so on. You could do it with SVN, but you are much better off with Git.
  SVN simply can not manage any project of any size with any merge workflow. Git can.

Again, their nature is fundamentally different (which then leads to different implementation but that is not the point).
One see revision control as directories and files, the other only see the content of the file (so much so that empty directories won't even register in Git!).

The general end-goal might be the same, but you cannot use them in the same way, nor can you solve the same class of problem (in scope or complexity).

You can also simply go to xcode preferences then accounts and then it may ask you to simply re sign in with your developer profile and then the issues should go away.

Hope this Helps!

Use Console.Read(); to prevent the program from closing, but make sure you add the Console.Read(); code before return statement, or else it will be a unreachable code .

    Console.Read(); 
    return 0; 

check this Console.Read

If you have zgrep you can use

zgrep -a string file.tar.gz

If you're using Visual C#, all you need to do is add a class in Program.cs inheriting Form and change all the inherited class from Form to your class in every Form*.cs.

//Program.cs
public class Forms : Form
{
    //Declare your global valuables here.
}

//Form1.cs
public partial class Form1 : Forms    //Change from Form to Forms
{
    //...
}

Of course, there might be a way to extending the class Form without modifying it. If that's the case, all you need to do is extending it! Since all the forms are inheriting it by default, so all the valuables declared in it will become global automatically! Good luck!!!

Configure your webserver to send caching control HTTP headers for the script.

Fake headers in the HTML documents:

1. Aren't as well supported as real HTTP headers
2. Apply to the HTML document, not to resources that it links to

isset is intended to be used only for variables and not just values, so isset("foobar") will raise an error. As of PHP 5.5, empty supports both variables and expressions.

So your first question should rather be if isset returns true for a variable that holds an empty string. And the answer is:

$var = "";
var_dump(isset($var));

The type comparison tables in PHP’s manual is quite handy for such questions.

isset basically checks if a variable has any value other than null since non-existing variables have always the value null. empty is kind of the counter part to isset but does also treat the integer value 0 and the string value "0" as empty. (Again, take a look at the type comparison tables.)

There is a way to make youtube autoplay, and complete playlists play through. Get Adblock browser for Android, and then go to the youtube website, and and configure it for the desktop version of the page, close Adblock browser out, and then reopen, and you will have the desktop version, where autoplay will work.

Using the desktop version will also mean that AdBlock will work. The mobile version invokes the standalone YouTube player, which is why you want the desktop version of the page, so that autoplay will work, and so ad blocking will work.

Are you sure you're using the correct proxy as system properties?

Also if you are using 1.5 or 1.6 you could pass a java.net.Proxy instance to the openConnection() method. This is more elegant imo:

//Proxy instance, proxy ip = 10.0.0.1 with port 8080
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.0.0.1", 8080));
conn = new URL(urlString).openConnection(proxy);

I have searched and searched and played and played with it and although it is not perfect it may help others making the attempt to validate first and last names that have been provided as one variable.

In my case, that variable is $name.

I used the following code for my PHP:

    if (preg_match('/\b([A-Z]{1}[a-z]{1,30}[- ]{0,1}|[A-Z]{1}[- \']{1}[A-Z]{0,1}  
    [a-z]{1,30}[- ]{0,1}|[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}){2,5}/', $name)  
    # there is no space line break between in the above "if statement", any that   
    # you notice or perceive are only there for formatting purposes.  
    # 
    # pass - successful match - do something
    } else {
    # fail - unsuccessful match - do something

I am learning RegEx myself but I do have the explanation for the code as provided by RegEx buddy.
Here it is:

Assert position at a word boundary «\b»

Match the regular expression below and capture its match into backreference number 1
«([A-Z]{1}[a-z]{1,30}[- ]{0,1}|[A-Z]{1}[- \']{1}[A-Z]{0,1}[a-z]{1,30}[- ]{0,1}|[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}){2,5}»

Between 2 and 5 times, as many times as possible, giving back as needed (greedy) «{2,5}»

* I NEED SOME HELP HERE WITH UNDERSTANDING THE RAMIFICATIONS OF THIS NOTE *

Note: I repeated the capturing group itself. The group will capture only the last iteration. Put a capturing group around the repeated group to capture all iterations. «{2,5}»

Match either the regular expression below (attempting the next alternative only if this one fails) «[A-Z]{1}[a-z]{1,30}[- ]{0,1}»

Match a single character in the range between “A” and “Z” «[A-Z]{1}»

Exactly 1 times «{1}»

Match a single character in the range between “a” and “z” «[a-z]{1,30}»

Between one and 30 times, as many times as possible, giving back as needed (greedy) «{1,30}»

Match a single character present in the list “- ” «[- ]{0,1}»

Between zero and one times, as many times as possible, giving back as needed (greedy) «{0,1}»

Or match regular expression number 2 below (attempting the next alternative only if this one fails) «[A-Z]{1}[- \']{1}[A-Z]{0,1}[a-z]{1,30}[- ]{0,1}»

Match a single character in the range between “A” and “Z” «[A-Z]{1}»

Exactly 1 times «{1}»

Match a single character present in the list below «[- \']{1}»

Exactly 1 times «{1}»

One of the characters “- ” «- » A ' character «\'»

Match a single character in the range between “A” and “Z” «[A-Z]{0,1}»

Between zero and one times, as many times as possible, giving back as needed (greedy) «{0,1}»

Match a single character in the range between “a” and “z” «[a-z]{1,30}»

Between one and 30 times, as many times as possible, giving back as needed (greedy) «{1,30}»

Match a single character present in the list “- ” «[- ]{0,1}»

Between zero and one times, as many times as possible, giving back as needed (greedy) «{0,1}»

Or match regular expression number 3 below (the entire group fails if this one fails to match) «[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}»

Match a single character in the range between “a” and “z” «[a-z]{1,2}»

Between one and 2 times, as many times as possible, giving back as needed (greedy) «{1,2}»

Match a single character in the range between “ ” and “'” «[ -\']{1}»

Exactly 1 times «{1}»

Match a single character in the range between “A” and “Z” «[A-Z]{1}»

Exactly 1 times «{1}»

Match a single character in the range between “a” and “z” «[a-z]{1,30}»

Between one and 30 times, as many times as possible, giving back as needed (greedy) «{1,30}»

I know this validation totally assumes that every person filling out the form has a western name and that may eliminates the vast majority of folks in the world. However, I feel like this is a step in the proper direction. Perhaps this regular expression is too basic for the gurus to address simplistically or maybe there is some other reason that I was unable to find the above code in my searches. I spent way too long trying to figure this bit out, you will probably notice just how foggy my mind is on all this if you look at my test names below.

I tested the code on the following names and the results are in parentheses to the right of each name.

1. STEVE SMITH (fail)
2. Stev3 Smith (fail)
3. STeve Smith (fail)
4. Steve SMith (fail)
5. Steve Sm1th (passed on the Steve Sm)
6. d'Are to Beaware (passed on the Are to Beaware)
7. Jo Blow (passed)
8. Hyoung Kyoung Wu (passed)
9. Mike O'Neal (passed)
10. Steve Johnson-Smith (passed)
11. Jozef-Schmozev Hiemdel (passed)
12. O Henry Smith (passed)
13. Mathais d'Arras (passed)
14. Martin Luther King Jr (passed)
15. Downtown-James Brown (passed)
16. Darren McCarty (passed)
17. George De FunkMaster (passed)
18. Kurtis B-Ball Basketball (passed)
19. Ahmad el Jeffe (passed)

If you have basic names, there must be more than one up to five for the above code to work, that are similar to those that I used during testing, this code might be for you.

If you have any improvements, please let me know. I am just in the early stages (first few months of figuring out RegEx.

Thanks and good luck, Steve

On Linux, you can get ELF header information by using either of the following two commands:

file {YOUR_JRE_LOCATION_HERE}/bin/java

o/p: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), for GNU/Linux 2.4.0, not stripped

or

readelf -h {YOUR_JRE_LOCATION_HERE}/bin/java | grep 'Class'

o/p: Class: ELF64

You're correct, length is a data member, not a method.

From the Arrays tutorial:

The length of an array is established when the array is created. After creation, its length is fixed.

RFC 7111

There is an RFC which covers it and says to use text/csv.

This RFC updates RFC 4180.

Excel

Recently I discovered an explicit mimetype for Excel application/vnd.ms-excel. It was registered with IANA in '96. Note the concerns raised about being at the mercy of the sender and having your machine violated.

Media Type: application/vnd.ms-excel

Name Microsoft Excel (tm)

Required parameters: None

Optional parameters: name

Encoding considerations: base64 preferred

Security considerations: As with most application types this data is intended for interpretation by a program that understands the data on the recipient's system. Recipients need to understand that they are at the "mercy" of the sender, when receiving this type of data, since data will be executed on their system, and the security of their machines can be violated.

OID { org-id ms-files(4) ms-excel (3) }

Object type spreadsheet

Comments This Media Type/OID is used to identify Microsoft Excel generically (i.e., independent of version, subtype, or platform format).

I wasn't aware that vendor extensions were allowed. Check out this answer to find out more - thanks starbeamrainbowlabs for the reference.

Here is an updated fiddle: http://jsfiddle.net/UKySp/

You needed to set your initial model value to the actual object:

$scope.feed.config = $scope.configs[0];

And update your select to look like this:

<select ng-model="feed.config" ng-options="item.name for item in configs">

Instead of writing this amount of code to make a simple call, you could use one of the wrappers available over the internet.

My solution is to define a merge function. It's not sophisticated and just cost one line. Here's the code in Python 3.

from functools import reduce
from operator import or_

def merge(*dicts):
    return { k: reduce(lambda d, x: x.get(k, d), dicts, None) for k in reduce(or_, map(lambda x: x.keys(), dicts), set()) }

Tests

>>> d = {0: 0, 1: 1, 2: 4, 3: 9, 4: 16}
>>> d_letters = {0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}
>>> merge(d, d_letters)
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}

It works for arbitrary number of dictionary arguments. Were there any duplicate keys in those dictionary, the key from the rightmost dictionary in the argument list wins.

If you are writing React-Native class with ES6, following format will be followed. It includes life cycle methods of RN for the class making network calls.

import React, {Component} from 'react';
import {

import * as Progress from 'react-native-progress';

export default class RNClass extends Component{
     constructor(props){
          super(props);

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

In Angular 6, with your router you can use:

RouterModule.forRoot(routes, { useHash: false })

It depends how you wish the function to work.

If all you wish to do is test for the word 'true' inside the string, and define any string (or nonstring) that doesn't have it as false, the easiest way is probably this:

function parseBoolean(str) {
  return /true/i.test(str);
}

If you wish to assure that the entire string is the word true you could do this:

function parseBoolean(str) {
  return /^true$/i.test(str);
}

You use this code in your button click event

// Check if no view has focus:
View view = this.getCurrentFocus();
if (view != null) {  
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

I think it's better to use importlib.import_module('.c', __name__) since you don't need to know about a and b.

I'm also wondering that, if you have to use importlib.import_module('a.b.c'), why not just use import a.b.c?

I think your problem is that

int selection = scanner.nextInt();

reads just the number, not the end of line or anything after the number. When you declare

String sentence = scanner.nextLine();

This reads the remainder of the line with the number on it (with nothing after the number I suspect)

Try placing a scanner.nextLine(); after each nextInt() if you intend to ignore the rest of the line.

You have to use execute immediate (dynamic sql).

DECLARE 
v_owner varchar2(40); 
v_table_name varchar2(40); 
cursor get_tables is 
select distinct table_name,user 
from user_tables 
where lower(user) = 'schema_name'; 
begin 
open get_tables; 
loop
    fetch get_tables into v_table_name,v_owner; 
    EXIT WHEN get_tables%NOTFOUND;
    execute immediate 'INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED) 
    SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'')     FROM ' || v_table_name; 
end loop;
CLOSE get_tables; 
END; 

There are 2 differences:

2 methods creating a user and granting some privileges to him

create user userName identified by password;
grant connect to userName;

and

grant connect to userName identified by password;

do exactly the same. It creates a user and grants him the connect role.

different outcome

resource is a role in oracle, which gives you the right to create objects (tables, procedures, some more but no views!). ALL PRIVILEGES grants a lot more of system privileges.

To grant a user all privileges run you first snippet or

grant all privileges to userName identified by password;

This is one of the "hard problems" surrounding development. As far as I know there are no perfect solutions.

If you only need to store the database structure and not the data you can export the database as SQL queries. (in Enterprise Manager: Right click on database -> Generate SQL script. I recommend setting the "create one file per object" on the options tab) You can then commit these text files to svn and make use of svn's diff and logging functions.

I have this tied together with a Batch script that takes a couple parameters and sets up the database. I also added some additional queries that enter default data like user types and the admin user. (If you want more info on this, post something and I can put the script somewhere accessible)

If you need to keep all of the data as well, I recommend keeping a back up of the database and using Redgate (http://www.red-gate.com/) products to do the comparisons. They don't come cheap, but they are worth every penny.

try with below on powershell:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted
import-module [\path\]XMLHelpers.psm1

Instead of [] put the full path

Full explanation of this and that

No, there is no API for Google Voice announced as of 2021.

"pygooglevoice" can perform most of the voice functions from Python. It can send SMS. I've developed code to receive SMS messages, but the overhead is excessive given the current Google Voice interface. Each poll returns over 100K of content, so you'd use a quarter-gigabyte a day just polling every 30 seconds. There's a discussion on Google Code about this.

Try To Give Full path for reading image.

Example image = ImageIO.read(new File("D:/work1/Jan14Stackoverflow/src/Strawberry.jpg"));

your code is not producing any exception after giving the full path. If you want to just read an image file in java code. Refer the following - http://docs.oracle.com/javase/tutorial/2d/images/examples/LoadImageApp.java

If the object of your class is created at end your code works fine for me and displays the image

// PracticeFrame pframe = new PracticeFrame();//comment this

new PracticeFrame().add(panel);

try this

#center_div
{
       margin: auto;
       position: absolute;
       top: 0; 
       left: 0;
       bottom: 0; 
       right: 0;
 }

CSS supports text input for colors (i.e. "black" = #000000 "white" = #ffffff) So I think the helpful solution we are looking for here is how can one have PHP take the output from an HTML form text input box and have it tell CSS to use this line of text for background color.

So that when a a user types "blue" into the text field titled "what is your favorite color", they are returned a page with a blue background, or whatever color they happen to type in so long as it is recognized by CSS.

I believe Dan is on the right track, but may need to elaborate for use PHP newbies, when I try this I am returned a green screen no matter what is typed in (I even set this up as an elseif to display a white background if no data is entered in the text field, still green?

In order to center text in md files you can use the center tag like html tag:

<center>Centered text</center>

Try this:

import pandas as pd
DataFrame = pd.read_csv("dataset.tsv", sep="\t")

I'm a total novice but surely this is cleaner and more controlled

def main():
    try:
        Answer = 1/0
        print  Answer
    except:
        print 'Program terminated'
        return
    print 'You wont see this'

if __name__ == '__main__': 
    main()

...

Program terminated

than

import sys
def main():
    try:
        Answer = 1/0
        print  Answer
    except:
        print 'Program terminated'
        sys.exit()
    print 'You wont see this'

if __name__ == '__main__': 
    main()

...

Program terminated Traceback (most recent call last): File "Z:\Directory\testdieprogram.py", line 12, in main() File "Z:\Directory\testdieprogram.py", line 8, in main sys.exit() SystemExit

Edit

The point being that the program ends smoothly and peacefully, rather than "I'VE STOPPED !!!!"

EDIT Summary and reccomendations

Using a for each cell in range construct is not in itself slow. What is slow is repeated access to Excel in the loop (be it reading or writing cell values, format etc, inserting/deleting rows etc).

What is too slow depends entierly on your needs. A Sub that takes minutes to run might be OK if only used rarely, but another that takes 10s might be too slow if run frequently.

So, some general advice:

1. keep it simple at first. If the result is too slow for your needs, then optimise
2. focus on optimisation of the content of the loop
3. don't just assume a loop is needed. There are sometime alternatives
4. if you need to use cell values (a lot) inside the loop, load them into a variant array outside the loop.
5. a good way to avoid complexity with inserts is to loop the range from the bottom up
   (for index = max to min step -1)
6. if you can't do that and your 'insert a row here and there' is not too many, consider reloading the array after each insert
7. If you need to access cell properties other than value, you are stuck with cell references
8. To delete a number of rows consider building a range reference to a multi area range in the loop, then delete that range in one go after the loop

eg (not tested!)

Dim rngToDelete as range
for each rw in rng.rows
    if need to delete rw then

        if rngToDelete is nothing then
            set rngToDelete = rw
        else
            set rngToDelete = Union(rngToDelete, rw)
        end if

    endif
next
rngToDelete.EntireRow.Delete

Original post

Conventional wisdom says that looping through cells is bad and looping through a variant array is good. I too have been an advocate of this for some time. Your question got me thinking, so I did some short tests with suprising (to me anyway) results:

test data set: a simple list in cells A1 .. A1000000 (thats 1,000,000 rows)

Test case 1: loop an array

Dim v As Variant
Dim n As Long

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    'i = i + 1
    'i = r.Cells(n, 1).Value 'i + 1
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Array Count = " & Format(n, "#,###")

Result:

Array Time = 0.249 sec
Array Count = 1,000,001

Test Case 2: loop the range

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 0.296 sec
Range Count = 1,000,000

So,looping an array is faster but only by 19% - much less than I expected.

Test 3: loop an array with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    i = r.Cells(n, 1).Value
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Array Count = " & Format(i, "#,###")

Result:

Array Time = 5.897 sec
Array Count = 1,000,000

Test case 4: loop range with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
    i = c.Value
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 2.356 sec
Range Count = 1,000,000

So event with a single simple cell reference, the loop is an order of magnitude slower, and whats more, the range loop is twice as fast!

So, conclusion is what matters most is what you do inside the loop, and if speed really matters, test all the options

FWIW, tested on Excel 2010 32 bit, Win7 64 bit All tests with

• ScreenUpdating off,
• Calulation manual,
• Events disabled.

You could add your JSON file as an external using webpack config. Then you can load up that json in any of your react modules.

Take a look at this answer

If you want to change the default container and you are using Virtualbox, you can do it via the commandline / CLI:

docker-machine stop
VBoxManage modifyvm default --cpus 2
VBoxManage modifyvm default --memory 4096
docker-machine start

You can simply implement your own compare function

[compareWith]="compareItems"

See as well the docu. So the complete code would look like:

  <div>
    <mat-select
        [(value)]="selected2" [compareWith]="compareItems">
      <mat-option
          *ngFor="let option of options2"
          value="{{ option.id }}">
        {{ option.name }}
      </mat-option>
    </mat-select>
  </div>

and in the Typescript file:

  compareItems(i1, i2) {
    return i1 && i2 && i1.id===i2.id;
  }

Plugin: jupyter-vim

So you can send lines (<leader>E), visual selection (<leader>e) to a running jupyter-client (the replacement of ipython)

I prefer to separate editor and interpreter (each one in its shell). Imagine you send a bad input reading command ...

Try with below code sample.it is working for me

var date_input_field = $('input[name="date"]');
    date_input_field .datepicker({
        dateFormat: '/dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
    }).on('change', function(selected){
        alert("startDate..."+selected.timeStamp);
    });

If you want to see landscape on the screen before you print, as well as printing, then in your css, you can set the width to 900px, and the height to 612px.

OP didn't mention A4 size. I assume it's Letter size in my numbers above.

As you said, in MySQL USAGE is synonymous with "no privileges". From the MySQL Reference Manual:

The USAGE privilege specifier stands for "no privileges." It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges.

USAGE is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE. It corresponds to a row in the `mysql`.`user` table with no privileges set.

The IDENTIFIED BY clause indicates that a password is set for that user. How do we know a user is who they say they are? They identify themselves by sending the correct password for their account.

A user's password is one of those global level account attributes that isn't tied to a specific database or table. It also lives in the `mysql`.`user` table. If the user does not have any other privileges ON *.*, they are granted USAGE ON *.* and their password hash is displayed there. This is often a side effect of a CREATE USER statement. When a user is created in that way, they initially have no privileges so they are merely granted USAGE.

Supervised Machine Learning

"The process of an algorithm learning from training dataset and predict the output. "

Accuracy of predicted output directly proportional to the training data (length)

Supervised learning is where you have input variables (x) (training dataset) and an output variable (Y) (testing dataset) and you use an algorithm to learn the mapping function from the input to the output.

Y = f(X)

Major types:

• Classification (discrete y-axis)
• Predictive (continuous y-axis)

Algorithms:

• Classification Algorithms:

  Neural Networks  
  Naïve Bayes classifiers  
  Fisher linear discriminant  
  KNN 
  Decision Tree 
  Super Vector Machines
  

• Predictive Algorithms:

  Nearest  neighbor  
  Linear Regression,Multi Regression 
  

Application areas:

1. Classifying emails as spam
2. Classifying whether patient has disease or not

3. Voice Recognition

4. Predict the HR select particular candidate or not

5. Predict the stock market price

Run Gunicorn with --log-level debug.

It should give you an app stack trace.

its all because you installed greater then 5.6 version of the mysql

Solutions

1.you can degrade mysql version solution

2 reconfigure authentication to native type or legacy type authentication using
configure option

Here is another take, "stolen" from a comment at can't compare datetime.datetime to datetime.date ... convert the date to a datetime using this construct:

datetime.datetime(d.year, d.month, d.day)

Suggestion:

from datetime import datetime

def ensure_datetime(d):
    """
    Takes a date or a datetime as input, outputs a datetime
    """
    if isinstance(d, datetime):
        return d
    return datetime.datetime(d.year, d.month, d.day)

def datetime_cmp(d1, d2):
    """
    Compares two timestamps.  Tolerates dates.
    """
    return cmp(ensure_datetime(d1), ensure_datetime(d2))

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25));

The above will extract the text of a tag, then extract again assign it back.

For Swift with a UINavigationController:

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    if self.navigationController?.topViewController != self {
        print("back button tapped")
    }
}

If someone looking for calling a script with arguments

import subprocess

val = subprocess.check_call("./script.sh '%s'" % arg, shell=True)

Remember to convert the args to string before passing, using str(arg).

This can be used to pass as many arguments as desired:

subprocess.check_call("./script.ksh %s %s %s" % (arg1, str(arg2), arg3), shell=True)

Treat IllegalArgumentException as a preconditions check, and consider the design principle: A public method should both know and publicly document its own preconditions.

I would agree this example is correct:

void setPercentage(int pct) {
    if( pct < 0 || pct > 100) {
         throw new IllegalArgumentException("bad percent");
     }
}

If EmailUtil is opaque, meaning there's some reason the preconditions cannot be described to the end-user, then a checked exception is correct. The second version, corrected for this design:

import com.someoneelse.EmailUtil;

public void scanEmail(String emailStr, InputStream mime) throws ParseException {
    EmailAddress parsedAddress = EmailUtil.parseAddress(emailStr);
}

If EmailUtil is transparent, for instance maybe it's a private method owned by the class under question, IllegalArgumentException is correct if and only if its preconditions can be described in the function documentation. This is a correct version as well:

/** @param String email An email with an address in the form [email protected]
 * with no nested comments, periods or other nonsense.
 */
public String scanEmail(String email)
  if (!addressIsProperlyFormatted(email)) {
      throw new IllegalArgumentException("invalid address");
  }
  return parseEmail(emailAddr);
}
private String parseEmail(String emailS) {
  // Assumes email is valid
  boolean parsesJustFine = true;
  // Parse logic
  if (!parsesJustFine) {
    // As a private method it is an internal error if address is improperly
    // formatted. This is an internal error to the class implementation.
    throw new AssertError("Internal error");
  }
}

This design could go either way.

• If preconditions are expensive to describe, or if the class is intended to be used by clients who don't know whether their emails are valid, then use ParseException. The top level method here is named scanEmail which hints the end user intends to send unstudied email through so this is likely correct.
• If preconditions can be described in function documentation, and the class does not intent for invalid input and therefore programmer error is indicated, use IllegalArgumentException. Although not "checked" the "check" moves to the Javadoc documenting the function, which the client is expected to adhere to. IllegalArgumentException where the client can't tell their argument is illegal beforehand is wrong.

A note on IllegalStateException: This means "this object's internal state (private instance variables) is not able to perform this action." The end user cannot see private state so loosely speaking it takes precedence over IllegalArgumentException in the case where the client call has no way to know the object's state is inconsistent. I don't have a good explanation when it's preferred over checked exceptions, although things like initializing twice, or losing a database connection that isn't recovered, are examples.

GNU Trove support this but not using generics. http://trove4j.sourceforge.net/javadocs/gnu/trove/TObjectIntHashMap.html

The simple solution: Add the following to the very top of the php file you are requesting the data from.

header("Access-Control-Allow-Origin: *");

No, you'll need to do it manually.

function prettyDate(date) {_x000D_
  var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',_x000D_
                'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];_x000D_
_x000D_
  return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();_x000D_
}_x000D_
_x000D_
console.log(prettyDate(new Date(1324339200000)));

I can't comment yet but thought I'd add that if you have a UISearchController on your controller with UISearchBar as your tableHeaderView, setting the height of the first section as 0 in heightForHeaderInSection does indeed work.

I use self.tableView.contentOffset = CGPointMake(0, self.searchController.searchBar.frame.size.height); so that the search bar is hidden by default.

Result is that there is no header for the first section, and scrolling down will show the search bar right above the first row.

Give full path as input. Avoid relative paths.

 return File.Exists(FinalPath);

bool b = list.Contains("Hello", StringComparer.CurrentCultureIgnoreCase);

[EDIT] extension code:

public static bool Contains(this string source, string cont
                                                    , StringComparison compare)
{
    return source.IndexOf(cont, compare) >= 0;
}

This could work :)

This way works for me, (using Spring Boot version 2.0.1. RELEASE):

@Query("SELECT u.username FROM User u WHERE u.username LIKE %?1%")
List<String> findUsersWithPartOfName(@Param("username") String username);

Explaining: The ?1, ?2, ?3 etc. are place holders the first, second, third parameters, etc. In this case is enough to have the parameter is surrounded by % as if it was a standard SQL query but without the single quotes.

select count(*) 
from table_emp 
 where DATEPART(YEAR, ARR_DATE) = '2012' AND DATEPART(MONTH, ARR_DATE) = '01'

@Entity
@NamedQuery(name = "Customer.listUniqueNames", 
            query = "SELECT DISTINCT c.name FROM Customer c")
public class Customer {
        ...

        private String name;

        public static List<String> listUniqueNames() {
             return = getEntityManager().createNamedQuery(
                   "Customer.listUniqueNames", String.class)
                   .getResultList();
        }
}

For Windows.

In Android Studio:

Tools > Android > AVD Manager > Your Device > Pencil Icon> Show Advanced Settings > Memory and Storage > RAM > Set RAM to your preferred size.

In Control Panel:

Programs and Features > Intel Hardware Accelerated Execution Manager > Change > Set manually > Set RAM to your preferred size.

It is better for RAM sizes set in both places to be the same.

I had the same problem as you though I have followed a different guide: http://www.mkyong.com/webservices/jax-rs/jersey-hello-world-example/

The strange part is that, in this guide I have used, I should not have any problem with compatibility between versions (1.x against 2.x) because following the guide you use the jersey 1.8.x on pom.xmland in the web.xmlyou refer to a class (com.sun.jersey.spi.container.servlet.ServletContainer) as said before of 1.x version. So as I can infer this should be working.

My guess is because I'm using JDK 1.7 this class does not exist anymore.

After, I tried to resolve with the answers before mine, did not helped, I have made changes on the pom.xmland on the web.xml the error changed to: java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

Which supposedly should be exist!

As result of this error, I found a "new" solution: http://marek.potociar.net/2013/06/13/jax-rs-2-0-and-jersey-2-0-released/

With Maven (archetypes), generate a jersey project, likes this:

mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes -DarchetypeArtifactId=jersey-quickstart-webapp -DarchetypeVersion=2.0

And it worked for me! :)

sudo npm install -g @angular/cli

If your task is performing some kind of action in a loop there is a way to pause/restart processing, but I think it would have to be outside what the Thread API currently offers. If its a single shot process I am not aware of any way to suspend/restart without running into API that has been deprecated or is no longer allowed.

As for looped processes, the easiest way I could think of is that the code that spawns the Task instantiates a ReentrantLock and passes it to the task, as well as keeping a reference itself. Every time the Task enters its loop it attempts a lock on the ReentrantLock instance and when the loop completes it should unlock. You may want to encapsulate all this try/finally, making sure you let go of the lock at the end of the loop, even if an exception is thrown.

If you want to pause the task simply attempt a lock from the main code (since you kept a reference handy). What this will do is wait for the loop to complete and not let it start another iteration (since the main thread is holding a lock). To restart the thread simply unlock from the main code, this will allow the task to resume its loops.

To permanently stop the thread I would use the normal API or leave a flag in the Task and a setter for the flag (something like stopImmediately). When the loop encountered a true value for this flag it stops processing and completes the run method.

This is something I wrote a few minutes ago just messing around. Hope it helps!

You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:

Just query the "memberOf" property and iterate though the return, example:

            search.PropertiesToLoad.Add("memberOf");
            StringBuilder groupNames = new StringBuilder(); //stuff them in | delimited

                SearchResult result = search.FindOne();

                String dn;
                int equalsIndex, commaIndex;

                for (int propertyCounter = 0; propertyCounter < propertyCount;
                    propertyCounter++)
                {
                    dn = (String)result.Properties["memberOf"][propertyCounter];

                    equalsIndex = dn.IndexOf("=", 1);
                    commaIndex = dn.IndexOf(",", 1);
                    if (-1 == equalsIndex)
                    {
                        return null;
                    }
                    groupNames.Append(dn.Substring((equalsIndex + 1),
                                (commaIndex - equalsIndex) - 1));
                    groupNames.Append("|");
                }

            return groupNames.ToString();

This just stuffs the group names into the groupNames string, pipe delimited, but when you spin through you can do whatever you want with them

I prefer Consolas.

Data Abstraction: DA is simply filtering the concrete item. By the class we can achieve the pure abstraction, because before creating the class we can think only about concerned information about the class.

Encapsulation: It is a mechanism, by which we protect our data from outside.

First you'll need to Install it:

• If you're using a distro which packages LaTeX (almost all will do) then look for texlive or tetex. TeX Live is the newer of the two, and is replacing tetex on most distributions now.

If you're using Debian or Ubuntu, something like:

<code>apt-get install texlive</code>

..will get it installed.

RedHat or CentOS need:

<code>yum install tetex</code>

Note : This needs root permissions, so either use su to switch user to root, or prefix the commands with sudo, if you aren't already logged in as the root user.

Next you'll need to get a text editor. Any editor will do, so whatever you are comfortable with. You'll find that advanced editors like Emacs (and vim) add a lot of functionality and so will help with ensuring that your syntax is correct before you try and build your document output.

Create a file called test.tex and put some content in it, say the example from the LaTeX primer:

\documentclass[a4paper,12pt]{article}
\begin{document}

The foundations of the rigorous study of \emph{analysis}
were laid in the nineteenth century, notably by the
mathematicians Cauchy and Weierstrass. Central to the
study of this subject are the formal definitions of
\emph{limits} and \emph{continuity}.

Let $D$ be a subset of $\bf R$ and let
$f \colon D \to \mathbf{R}$ be a real-valued function on
$D$. The function $f$ is said to be \emph{continuous} on
$D$ if, for all $\epsilon > 0$ and for all $x \in D$,
there exists some $\delta > 0$ (which may depend on $x$)
such that if $y \in D$ satisfies
\[ |y - x| < \delta \]
then
\[ |f(y) - f(x)| < \epsilon. \]

One may readily verify that if $f$ and $g$ are continuous
functions on $D$ then the functions $f+g$, $f-g$ and
$f.g$ are continuous. If in addition $g$ is everywhere
non-zero then $f/g$ is continuous.

\end{document}

Once you've got this file you'll need to run latex on it to produce some output (as a .dvi file to start with, which is possible to convert to many other formats):

latex test.tex

This will print a bunch of output, something like this:

=> latex test.tex

This is pdfeTeX, Version 3.141592-1.21a-2.2 (Web2C 7.5.4)

Output written on test.dvi (1 page, 1508 bytes).
Transcript written on test.log.

..don't worry about most of this output -- the important part is the Output written on test.dvi line, which says that it was successful.

Now you need to view the output file with xdvi:

xdvi test.dvi &

This will pop up a window with the beautifully formatted output in it. Hit `q' to quit this, or you can leave it open and it will automatically update when the test.dvi file is modified (so whenever you run latex to update the output).

To produce a PDF of this you simply run pdflatex instead of latex:

pdflatex test.tex

..and you'll have a test.pdf file created instead of the test.dvi file.

After this is all working fine, I would suggest going to the LaTeX primer page and running through the items on there as you need features for documents you want to write.

Future things to consider include:

• Use tools such as xfig or dia to create diagrams. These can be easily inserted into your documents in a variety of formats. Note that if you are creating PDFs then you shouldn't use EPS (encapsulated postscript) for images -- use pdf exported from your diagram editor if possible, or you can use the epstopdf package to automatically convert from (e)ps to pdf for figures included with \includegraphics.

• Start using version control on your documents. This seems excessive at first, but being able to go back and look at earlier versions when you are writing something large can be extremely useful.

• Use make to run latex for you. When you start on having bibliographies, images and other more complex uses of latex you'll find that you need to run it over multiple files or multiple times (the first time updates the references, and the second puts references into the document, so they can be out-of-date unless you run latex twice...). Abstracting this into a makefile can save a lot of time and effort.

• Use a better editor. Something like Emacs + AUCTeX is highly competent. This is of course a highly subjective subject, so I'll leave it at that (that and that Emacs is clearly the best option :)

Spring-integration example, routing based on a an Enum field:

public class BookOrder {

    public enum OrderType { DELIVERY, PICKUP } //enum
    public BookOrder(..., OrderType orderType) //orderType
    ...

config:

<router expression="payload.orderType" input-channel="processOrder">
    <mapping value="DELIVERY" channel="delivery"/>
    <mapping value="PICKUP" channel="pickup"/>
</router>

The phpqrcode library is really fast to configure and the API documentation is easy to understand.

In addition to abaumg's answer I have attached 2 examples in PHP from http://phpqrcode.sourceforge.net/examples/index.php

1. QR code encoder

first include the library from your local path

include('../qrlib.php');

then to output the image directly as PNG stream do for example:

QRcode::png('your texte here...');

to save the result locally as a PNG image:

$tempDir = EXAMPLE_TMP_SERVERPATH;

$codeContents = 'your message here...';

$fileName = 'qrcode_name.png';

$pngAbsoluteFilePath = $tempDir.$fileName;
$urlRelativeFilePath = EXAMPLE_TMP_URLRELPATH.$fileName;

QRcode::png($codeContents, $pngAbsoluteFilePath); 

2. QR code decoder

See also the zxing decoder:

http://zxing.org/w/decode.jspx

Pretty useful to check the output.

3. List of Data format

A list of data format you can use in your QR code according to the data type :

• Website URL: http://stackoverflow.com (including the protocole http://)
• email address: mailto:[email protected]
• Telephone Number: +16365553344 (including country code)
• SMS Message: smsto:number:message
• MMS Message: mms:number:subject
• YouTube Video: youtube://ID (may work on iPhone, not standardized)

Ramil Amr's answer works only for the & character. If you have some other special characters, you should use PHP's htmlspecialchars() and JS's encodeURIComponent().

You can write:

var wysiwyg_clean = encodeURIComponent(wysiwyg);

And on the server side:

htmlspecialchars($_POST['wysiwyg']);

This will make sure that AJAX will pass the data as expected, and that PHP (in case your'e insreting the data to a database) will make sure the data works as expected.

plt.close() will close current instance.

plt.close(2) will close figure 2

plt.close(plot1) will close figure with instance plot1

plt.close('all') will close all fiures

Found here.

Remember that plt.show() is a blocking function, so in the example code you used above, plt.close() isn't being executed until the window is closed, which makes it redundant.

You can use plt.ion() at the beginning of your code to make it non-blocking, although this has other implications.

EXAMPLE

After our discussion in the comments, I've put together a bit of an example just to demonstrate how the plot functionality can be used.

Below I create a plot:

fig = plt.figure(figsize=plt.figaspect(0.75))
ax = fig.add_subplot(1, 1, 1)
....
par_plot, = plot(x_data,y_data, lw=2, color='red')

In this case, ax above is a handle to a pair of axes. Whenever I want to do something to these axes, I can change my current set of axes to this particular set by calling axes(ax).

par_plot is a handle to the line2D instance. This is called an artist. If I want to change a property of the line, like change the ydata, I can do so by referring to this handle.

I can also create a slider widget by doing the following:

axsliderA = axes([0.12, 0.85, 0.16, 0.075])
sA = Slider(axsliderA, 'A', -1, 1.0, valinit=0.5)
sA.on_changed(update)

The first line creates a new axes for the slider (called axsliderA), the second line creates a slider instance sA which is placed in the axes, and the third line specifies a function to call when the slider value changes (update).

My update function could look something like this:

def update(val):
    A = sA.val
    B = sB.val
    C = sC.val
    y_data = A*x_data*x_data + B*x_data + C
    par_plot.set_ydata(y_data)
    draw()

The par_plot.set_ydata(y_data) changes the ydata property of the Line2D object with the handle par_plot.

The draw() function updates the current set of axes.

Putting it all together:

from pylab import *
import matplotlib.pyplot as plt
import numpy

def update(val):
    A = sA.val
    B = sB.val
    C = sC.val
    y_data = A*x_data*x_data + B*x_data + C
    par_plot.set_ydata(y_data)
    draw()


x_data = numpy.arange(-100,100,0.1);

fig = plt.figure(figsize=plt.figaspect(0.75))
ax = fig.add_subplot(1, 1, 1)
subplots_adjust(top=0.8)

ax.set_xlim(-100, 100);
ax.set_ylim(-100, 100);
ax.set_xlabel('X')
ax.set_ylabel('Y')

axsliderA = axes([0.12, 0.85, 0.16, 0.075])
sA = Slider(axsliderA, 'A', -1, 1.0, valinit=0.5)
sA.on_changed(update)

axsliderB = axes([0.43, 0.85, 0.16, 0.075])
sB = Slider(axsliderB, 'B', -30, 30.0, valinit=2)
sB.on_changed(update)

axsliderC = axes([0.74, 0.85, 0.16, 0.075])
sC = Slider(axsliderC, 'C', -30, 30.0, valinit=1)
sC.on_changed(update)

axes(ax)
A = 1;
B = 2;
C = 1;
y_data = A*x_data*x_data + B*x_data + C;

par_plot, = plot(x_data,y_data, lw=2, color='red')

show()

A note about the above: When I run the application, the code runs sequentially right through (it stores the update function in memory, I think), until it hits show(), which is blocking. When you make a change to one of the sliders, it runs the update function from memory (I think?).

This is the reason why show() is implemented in the way it is, so that you can change values in the background by using functions to process the data.

Here's a simple Python script that will do the job:

import random, sys
lines = open(sys.argv[1]).readlines()
print(lines[random.randrange(len(lines))])

Usage:

python randline.py file_to_get_random_line_from

i was facing the same issue and solved it by removing the xmlns:wsu attribute.Try not adding it in the usernameToken.Hope this solves your issue too.

One thing that isn't mentioned in other answers is case sensitivity, if it is going to be referenced in multiple places (which it isn't in the original question but is worth taking into consideration as this question appears in a lot of similar searches). Based on other answers I found the following worked for me initially:

Request.Url.AbsoluteUri.ToString()

But in order to be more reliable this then became:

Request.Url.AbsoluteUri.ToString().ToLower()

And then for my requirements (checking what domain name the site is being accessed from and showing the relevant content):

Request.Url.AbsoluteUri.ToString().ToLower().Contains("xxxx")

This is a solution for all the YUI lovers out there:

Y.on('keydown', function() {
  if(event.keyCode == 13){
    Y.one("#id_of_button").simulate("click");
  }
}, '#id_of_textbox');

In this special case I did have better results using YUI for triggering DOM objects that have been injected with button functionality - but this is another story...

We just ran into this ourselves when running dotnet ef database update using ASP.Net Core 2.1; looks like relative paths aren't supported with AttachDbFileName.

System.Data.SqlClient.SqlException (0x80131904): Cannot attach the file '.\OurDbName.mdf' as database 'OurDbName'.

Just wanted to express that here for other people who might be bumping into this. The "fix" is use absolute paths.

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

ReducedForm is a type, so you cannot say

ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

You can only use the . operator on an instance:

ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

That's the same behavior I've seen: iframe's load() will fire first on an empty iframe, then the second time when your page is loaded.

Edit: Hmm, interesting. You could increment a counter in your event handler, and a) ignore the first load event, or b) ignore any duplicate load event.

TimeSpan.FromTicks(DateTime.Now.Ticks)

you can use plt.matshow() instead of plt.imshow() or you can use seaborn module's heatmap (see documentation) to plot the confusion matrix

import seaborn as sn
import pandas as pd
import matplotlib.pyplot as plt
array = [[33,2,0,0,0,0,0,0,0,1,3], 
        [3,31,0,0,0,0,0,0,0,0,0], 
        [0,4,41,0,0,0,0,0,0,0,1], 
        [0,1,0,30,0,6,0,0,0,0,1], 
        [0,0,0,0,38,10,0,0,0,0,0], 
        [0,0,0,3,1,39,0,0,0,0,4], 
        [0,2,2,0,4,1,31,0,0,0,2],
        [0,1,0,0,0,0,0,36,0,2,0], 
        [0,0,0,0,0,0,1,5,37,5,1], 
        [3,0,0,0,0,0,0,0,0,39,0], 
        [0,0,0,0,0,0,0,0,0,0,38]]
df_cm = pd.DataFrame(array, index = [i for i in "ABCDEFGHIJK"],
                  columns = [i for i in "ABCDEFGHIJK"])
plt.figure(figsize = (10,7))
sn.heatmap(df_cm, annot=True)

You have #include "fun.cpp" in mainfile.cpp so compiling with:

g++ -o hw1 mainfile.cpp

will work, however if you compile by linking these together like

g++ -g -std=c++11 -Wall -pedantic   -c -o fun.o fun.cpp
g++ -g -std=c++11 -Wall -pedantic   -c -o mainfile.o mainfile.cpp

As they mention above, adding #include "fun.hpp" will need to be done or it won't work. However, your case with the funct() function is slightly different than my problem.

I had this issue when doing a HW assignment and the autograder compiled by the lower bash recipe, yet locally it worked using the upper bash.

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

The php_flag and php_value inside a .htaccess file are technically correct - but for PHP installed as an Apache module only. On a shared host you'll almost never find such a setup; PHP is run as a CGI instead, for reasons related to security (keeping your server neighbours out of your files) and the way phpsuexec runs scripts as 'you' instead of the apache user.

Apache is thus correct giving you a server error: it doesn't know about the meaning of php_flag unless the PHP module is loaded. A CGI binary is to Apache an external program instead, and you can't configure it from within Apache.

Now for the good news: you can set up per-directory configuration putting there a file named 'php.ini' and setting there your instructions using the same syntax as in the system's main php.ini. The PHP manual lists all settable directives: you can set those marked with PHP_INI_PERDIR or PHP_INI_ALL, while only the system administrator can set those marked PHP_INI_SYSTEM in the server-wide php.ini.

Note that such php.ini directives are not inherited by subdirectories, you'll have to give them their own php.ini.

while (node.hasChildNodes()) {
    node.removeChild(node.lastChild);
}

The <Leader> key is mapped to \ by default. So if you have a map of <Leader>t, you can execute it by default with \+t. For more detail or re-assigning it using the mapleader variable, see

:help leader

To define a mapping which uses the "mapleader" variable, the special string
"<Leader>" can be used.  It is replaced with the string value of "mapleader".
If "mapleader" is not set or empty, a backslash is used instead.  
Example:
    :map <Leader>A  oanother line <Esc>
Works like:
    :map \A  oanother line <Esc>
But after:
    :let mapleader = ","
It works like:
    :map ,A  oanother line <Esc>

Note that the value of "mapleader" is used at the moment the mapping is
defined.  Changing "mapleader" after that has no effect for already defined
mappings.

One option is to give the <a> a display of inline-block and then apply text-align: center; on the containing block (remove the float as well):

div { 
    background: red;
    overflow: hidden; 
    text-align: center;
}

span a {
    background: #222;
    color: #fff;
    display: inline-block;
    /* float:left;  remove */
    margin: 10px 10px 0 0;
    padding: 5px 10px
}

When you use Apache with mod_php apache is enforced in prefork mode, and not worker. As, even if php5 is known to support multi-thread, it is also known that some php5 libraries are not behaving very well in multithreaded environments (so you would have a locale call on one thread altering locale on other php threads, for example).

So, if php is not running in cgi way like with php-fpm you have mod_php inside apache and apache in prefork mode. On your tests you have simply commented the prefork settings and increased the worker settings, what you now have is default values for prefork settings and some altered values for the shared ones :

StartServers       20
MinSpareServers    5
MaxSpareServers    10
MaxClients         1024
MaxRequestsPerChild  0

This means you ask apache to start with 20 process, but you tell it that, if there is more than 10 process doing nothing it should reduce this number of children, to stay between 5 and 10 process available. The increase/decrease speed of apache is 1 per minute. So soon you will fall back to the classical situation where you have a fairly low number of free available apache processes (average 2). The average is low because usually you have something like 5 available process, but as soon as the traffic grows they're all used, so there's no process available as apache is very slow in creating new forks. This is certainly increased by the fact your PHP requests seems to be quite long, they do not finish early and the apache forks are not released soon enough to treat another request.

See on the last graphic the small amount of green before the red peak? If you could graph this on a 1 minute basis instead of 5 minutes you would see that this green amount was not big enough to take the incoming traffic without any error message.

Now you set 1024 MaxClients. I guess the cacti graph are not taken after this configuration modification, because with such modification, when no more process are available, apache would continue to fork new children, with a limit of 1024 busy children. Take something like 20MB of RAM per child (or maybe you have a big memory_limit in PHP and allows something like 64MB or 256MB and theses PHP requests are really using more RAM), maybe a DB server... your server is now slowing down because you have only 768MB of RAM. Maybe when apache is trying to initiate the first 20 children you already reach the available RAM limit.

So. a classical way of handling that is to check the amount of memory used by an apache fork (make some top commands while it is running), then find how many parallel request you can handle with this amount of RAM (that mean parallel apache children in prefork mode). Let's say it's 12, for example. Put this number in apache mpm settings this way:

<IfModule prefork.c>
  StartServers       12
  MinSpareServers    12
  MaxSpareServers    12
  MaxClients         12
  MaxRequestsPerChild  300
</IfModule>

That means you do not move the number of fork while traffic increase or decrease, because you always want to use all the RAM and be ready for traffic peaks. The 300 means you recyclate each fork after 300 requests, it's better than 0, it means you will not have potential memory leaks issues. MaxClients is set to 12 25 or 50 which is more than 12 to handle the ListenBacklog queue, which can enqueue some requests, you may take a bigger queue, but you would get some timeouts maybe (removed this strange sentende, I can't remember why I said that, if more than 12 requests are incoming the next one will be pushed in the Backlog queue, but you should set MaxClient to your targeted number of processes).

And yes, that means you cannot handle more than 12 parallel requests.

If you want to handle more requests:

• buy some more RAM
• try to use apache in worker mode, but remove mod_php and use php as a parallel daemon with his own pooler settings (this is called php-fpm), connect it with fastcgi. Note that you will certainly need to buy some RAM to allow a big number of parallel php-fpm process, but maybe less than with mod_php
• Reduce the time spent in your php process. From your cacti graphs you have to potential problems: a real traffic peak around 11:25-11:30 or some php code getting very slow. Fast requests will reduce the number of parallel requests.

If your problem is really traffic peaks, solutions could be available with caches, like a proxy-cache server. If the problem is a random slowness in PHP then... it's an application problem, do you do some HTTP query to another site from PHP, for example?

And finally, as stated by @Jan Vlcinsky you could try nginx, where php will only be available as php-fpm. If you cannot buy RAM and must handle a big traffic that's definitively desserve a test.

Update: About internal dummy connections (if it's your problem, but maybe not).

Check this link and this previous answer. This is 'normal', but if you do not have a simple virtualhost theses requests are maybe hitting your main heavy application, generating slow http queries and preventing regular users to acces your apache processes. They are generated on graceful reload or children managment.

If you do not have a simple basic "It works" default Virtualhost prevent theses requests on your application by some rewrites:

  RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
  RewriteRule .* - [F,L]

Update:

Having only one Virtualhost does not protect you from internal dummy connections, it is worst, you are sure now that theses connections are made on your unique Virtualhost. So you should really avoid side effects on your application by using the rewrite rules.

Reading your cacti graphics, it seems your apache is not in prefork mode bug in worker mode. Run httpd -l or apache2 -l on debian, and check if you have worker.c or prefork.c. If you are in worker mode you may encounter some PHP problems in your application, but you should check the worker settings, here is an example:

<IfModule worker.c>
  StartServers           3
  MaxClients           500
  MinSpareThreads       75
  MaxSpareThreads      250 
  ThreadsPerChild       25
  MaxRequestsPerChild  300
</IfModule>

You start 3 processes, each containing 25 threads (so 3*25=75 parallel requests available by default), you allow 75 threads doing nothing, as soon as one thread is used a new process is forked, adding 25 more threads. And when you have more than 250 threads doing nothing (10 processes) some process are killed. You must adjust theses settings with your memory. Here you allow 500 parallel process (that's 20 process of 25 threads). Your usage is maybe more:

<IfModule worker.c>
  StartServers           2
  MaxClients           250
  MinSpareThreads       50
  MaxSpareThreads      150 
  ThreadsPerChild       25
  MaxRequestsPerChild  300
</IfModule>

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

• Preloading and the JavaScript Image() object

As einpoklum mentioned in their answer, since C++17 you can also use structured binding declarations. I want to extend on that by providing a full solution for iterating over a map of maps in a comfortable way:

int main() {
    std::map<std::string, std::map<std::string, std::string>> m {
        {"name1", {{"value1", "data1"}, {"value2", "data2"}}},
        {"name2", {{"value1", "data1"}, {"value2", "data2"}}},
        {"name3", {{"value1", "data1"}, {"value2", "data2"}}}
    };

    for (const auto& [k1, v1] : m)
        for (const auto& [k2, v2] : v1)
            std::cout << "m[" << k1 << "][" << k2 << "]=" << v2 << std::endl;

    return 0;
}

Note 1: For filling the map, I used an initializer list (which is a C++11 feature). This can sometimes be handy to keep fixed initializations compact.

Note 2: If you want to modify the map m within the loops, you have to remove the const keywords.

Code on Coliru

function get_time($time) {
    $duration = $time / 1000;
    $hours = floor($duration / 3600);
    $minutes = floor(($duration / 60) % 60);
    $seconds = $duration % 60;
    if ($hours != 0)
        echo "$hours:$minutes:$seconds";
    else
        echo "$minutes:$seconds";
}

get_time('1119241');

#include"stdio.h"//rmv coding for randam number access

#include"conio.h"

#include"time.h"

void main()
{
    time_t t;
    int rmvivek;

    srand(time(&t));
    rmvivek=1;

    while(rmvivek<=5)
    {
        printf("%c\t",rand()%10);
        rmvivek++;
    }
    getch();
}

Creating new oauth credentials worked for me

You might want to use helper library like http://momentjs.com/ which wraps the native javascript date object for easier manipulations

Then you can do things like:

var day = moment("12-25-1995", "MM-DD-YYYY");

or

var day = moment("25/12/1995", "DD/MM/YYYY");

then operate on the date

day.add('days', 7)

and to get the native javascript date

day.toDate();

Perhaps my nested for loops being used incorrectly?

Hint: nested loops won't work for this problem. A simple for loop won't work either.

You need to visualize the problem.

Write two ordered lists on a piece of paper, and using two fingers to point the elements of the respective lists, step through them as you do the merge in your head. Then translate your mental decision process into an algorithm and then code.

The optimal solution makes a single pass through the two lists.

Here is a simple way to send an HTML email, just by specifying the Content-Type header as 'text/html':

import email.message
import smtplib

msg = email.message.Message()
msg['Subject'] = 'foo'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
msg.add_header('Content-Type','text/html')
msg.set_payload('Body of <b>message</b>')

# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
s.starttls()
s.login(email_login,
        email_passwd)
s.sendmail(msg['From'], [msg['To']], msg.as_string())
s.quit()

use this code to redirect the page

echo "<script>alert('There are no fields to generate a report');document.location='admin/ahm/panel'</script>";

I will suggest to use Object.assign within a forEach() loop so that the objects are copied and does not affect the original array of objects

var res = [];
array.forEach(function(item) { 
    var tempItem = Object.assign({}, item);
    delete tempItem.bad; 
    res.push(tempItem);
});
console.log(res);

set -x

Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

[source]

Example

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30

set +x
echo `expr 10 + 20 `
30

Above example illustrates the usage of set -x. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

• First step expr has been evaluated.
• Second step echo has been evaluated.

when it comes to your shell script,

[ "$DEBUG" == 'true' ] && set -x

Your script might have been printing some additional lines of information when the execution mode selected as DEBUG. Traditionally people used to enable debug mode when a script called with optional argument such as -d
