VC++ is not actually a language but is commonly referred to like one. When VC++ is referred to as a language, it usually means Microsoft's implementation of C++, which contains various knacks that do not exist in regular C++, such as the __super keyword. It is similar to the various GNU extensions to the C language that are implemented in GCC.

You can concat origin and pathname, if theres present a port such as example.com:80, that will be included as well.

location.origin + location.pathname

Code to add audio to video using ffmpeg.

If audio length is greater than video length it will cut the audio to video length. If you want full audio in video remove -shortest from the cmd.

String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy", ,outputFile.getPath()};

private void execFFmpegBinaryShortest(final String[] command) {



            final File outputFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/videoaudiomerger/"+"Vid"+"output"+i1+".mp4");




            String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy","-shortest",outputFile.getPath()};


            try {

                ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {

What is stateless??

Once the request is made and the response is rendered back to the client the connection will be dropped or terminated. The server will forget all about the requester.

Why stateless??

The web chooses to go for the stateless protocol. It was a genius choice because the original goal of the web was to allow documents(web pages) to be served to extremely large no. of people using very basic hardware for the server.

Maintaining a long-running connection would have been extremely resource-intensive.

If the web were chosen the stateful protocol then the load on the server would have been increased to maintain the visitor's connection.

change parts of code like these:

There is nothing wrong with deleting items from the dictionary while iterating, as you've proposed. Be careful about multiple threads using the same dictionary at the same time, which may result in a KeyError or other problems.

Of course, see the docs at http://docs.python.org/library/stdtypes.html#typesmapping

Note that exponentiation by squaring is not the most optimal method. It is probably the best you can do as a general method that works for all exponent values, but for a specific exponent value there might be a better sequence that needs fewer multiplications.

For instance, if you want to compute x^15, the method of exponentiation by squaring will give you:

x^15 = (x^7)*(x^7)*x 
x^7 = (x^3)*(x^3)*x 
x^3 = x*x*x

This is a total of 6 multiplications.

It turns out this can be done using "just" 5 multiplications via addition-chain exponentiation.

n*n = n^2
n^2*n = n^3
n^3*n^3 = n^6
n^6*n^6 = n^12
n^12*n^3 = n^15

There are no efficient algorithms to find this optimal sequence of multiplications. From Wikipedia:

The problem of finding the shortest addition chain cannot be solved by dynamic programming, because it does not satisfy the assumption of optimal substructure. That is, it is not sufficient to decompose the power into smaller powers, each of which is computed minimally, since the addition chains for the smaller powers may be related (to share computations). For example, in the shortest addition chain for a¹5 above, the subproblem for a6 must be computed as (a³)² since a³ is re-used (as opposed to, say, a6 = a²(a²)², which also requires three multiplies).

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

There are several ways to do that. But do not just update to the earlier revision as suggested here.

The easiest way to revert the changes from a single revision, or from a range of revisions, is to use the revision log dialog. This is also the method to use of you want to discard recent changes and make an earlier revision the new HEAD.

1. Select the file or folder in which you need to revert the changes. If you want to revert all changes, this should be the top level folder.
2. Select TortoiseSVN ? Show Log to display a list of revisions. You may need to use Show All or Next 100 to show the revision(s) you are interested in.
3. Select the revision you wish to revert. If you want to undo a range of revisions, select the first one and hold Shift while selecting the last one. Note that for multiple revisions, the range must be unbroken with no gaps. Right click on the selected revision(s), then select Context Menu ? Revert changes from this revision.
4. Or if you want to make an earlier revision the new HEAD revision, right click on the selected revision, then select Context Menu ? Revert to this revision. This will discard all changes after the selected revision.

You have reverted the changes within your working copy. Check the results, then commit the changes.

All solutions are explained in the "How Do I..." part of the TortoiseSVN docs.

If using Vagrant try reloading your box. This solved my issue.

It is up to you. Just use the commit message as you wish. But it is easier if you are not switching between times and languages.

And if you develop in a team - it should be discussed and set fixed.

There is big difference between dot (".") and text() :-

• The dot (".") in XPath is called the "context item expression" because it refers to the context item. This could be match with a node (such as an element, attribute, or text node) or an atomic value (such as a string, number, or boolean). While text() refers to match only element text which is in string form.

• The dot (".") notation is the current node in the DOM. This is going to be an object of type Node while Using the XPath function text() to get the text for an element only gets the text up to the first inner element. If the text you are looking for is after the inner element you must use the current node to search for the string and not the XPath text() function.

For an example :-

<a href="something.html">
  <img src="filename.gif">
  link
</a>

Here if you want to find anchor a element by using text link, you need to use dot ("."). Because if you use //a[contains(.,'link')] it finds the anchor a element but if you use //a[contains(text(),'link')] the text() function does not seem to find it.

Hope it will help you..:)

Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!

If you're asking how to click a link via jQuery then assuming you have markup which looks like:

<a id="my-link" href="/relative/path.html">Click Me!</a>

You could click() it by executing:

$('#my-link').click();

There could be many, mainly IDEs dictate some trends and C++ conventions are also pushing. For C commonly:

• UNDERSCORED_UPPER_CASE (macro definitions, constants, enum members)
• underscored_lower_case (variables, functions)
• CamelCase (custom types: structs, enums, unions)
• uncappedCamelCase (oppa Java style)
• UnderScored_CamelCase (variables, functions under kind of namespaces)

Hungarian notation for globals are fine but not for types. And even for trivial names, please use at least two characters.

In your example one and two are char pointers, pointing to char constants. You cannot change the char constants pointed to by these pointers. So anything like:

strcat(one,two); // append string two to string one.

will not work. Instead you should have a separate variable(char array) to hold the result. Something like this:

char result[100];   // array to hold the result.

strcpy(result,one); // copy string one into the result.
strcat(result,two); // append string two to the result.

var pdf = MyPdf.pdf;
window.open(pdf);

This will open the pdf document in a full window from JavaScript

A function to open windows would look like this:

function openPDF(pdf){
  window.open(pdf);
  return false;
}

Please change small "mm" month to capital "MM" it will work.for reference below is the sample code.

        Date myDate = new Date();
        SimpleDateFormat sm = new SimpleDateFormat("MM-dd-yyyy");
       
        String strDate = sm.format(myDate);
        
        Date dt = sm.parse(strDate);
        System.out.println(strDate);

int i = 0;
bool b = Convert.ToBoolean(i);

You can simply use value_counts with sort option set to False. This will preserve ordering of the categories

df['colour'].value_counts(sort=False).plot.bar(rot=0)

i'd just do a simple check to see if d[a] exists and if not initialize it...

var a = "1",
    b = "hello",
    c = { "100" : "some important data" },
    d = {};

    if (d[a] === undefined) {
        d[a] = {}
    };
    d[a]["greeting"] = b;
    d[a]["data"] = c;

    console.debug (d);

For listing your tables use:

SELECT table_name FROM information_schema.tables WHERE table_schema='public'

It will only list tables that you create.

You can use PSCP to copy files from Windows to Linux.

1. Download PSCP from putty.org
2. Open cmd in the directory with pscp.exe file

3. Type command pscp source_file user@host:destination_file

   • Ex.
     pscp sample.txt [email protected]:/mydata/sample.txt

Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by

• saving some files into your document directory of the app
• move something from iCloud Drive to your app (in the move dialog the folder will show up). As soon as there are no files in your folder anymore, it's gonna disappear from the "on my iPad tab".

First install node-static server via npm install node-static -g -g is to install it global on your system, then navigate to the directory where your files are located, start the server with static it listens on port 8080, naviaget to the browser and type localhost:8080/yourhtmlfilename.

Simply disable default browser behaviour using preventDefault and pass the event within your HTML.

<a href=/foo onclick= yes_js_login(event)>Lorem ipsum</a>

yes_js_login = function(e) {
  e.preventDefault();
}

    $modelProduct       =   new Product();
    $shop_id            =   (int)Yii::$app->user->identity->shop_id;

    $queryProduct       =   $modelProduct->find()
                            ->where(['product.shop_id'  => $shop_id]);


    $dataProviderProduct    =   new ActiveDataProvider([
                                    'query'         =>  $queryProduct,
                                     'pagination' => [ 'pageSize' => 10 ],
                                    'sort'=> ['defaultOrder' => ['id'=>SORT_DESC]]
                                ]); 

You can check in all the below ways for a List

List<string> FilteredList = new List<string>();
//Comparing the two lists and gettings common elements.
FilteredList = a1.Intersect(a2, StringComparer.OrdinalIgnoreCase);

You can store images in MySQL as blobs. However, this is problematic for a couple of reasons:

• The images can be harder to manipulate: you must first retrieve them from the database before bulk operations can be performed.
• Except in very rare cases where the entire database is stored in RAM, MySQL databases are ultimately stored on disk. This means that your DB images are converted to blobs, inserted into a database, and then stored on disk; you can save a lot of overhead by simply storing them on disk.

Instead, consider updating your table to add an image_path field. For example:

ALTER TABLE `your_table`
ADD COLUMN `image_path` varchar(1024)

Then store your images on disk, and update the table with the image path. When you need to use the images, retrieve them from disk using the path specified.

An advantageous side-effect of this approach is that the images do not necessarily be stored on disk; you could just as easily store a URL instead of an image path, and retrieve images from any internet-connected location.

This is how I do it if I need a form displayed for each item, and inputs for various properties. Really depends on what I'm trying to do though.

ViewModel looks like this:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

View(with BeginForm of course):

@model MyViewModel


@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

Action:

[HttpPost]public ViewResult(MyViewModel vm)
{
...

Note that on post back only properties which had inputs available will have values. I.e., if Person had a .SSN property, it would not be available in the post action because it wasn't a field in the form.

Note that the way MVC's model binding works, it will only look for consecutive ID's. So doing something like this where you conditionally hide an item will cause it to not bind any data after the 5th item, because once it encounters a gap in the IDs, it will stop binding. Even if there were 10 people, you would only get the first 4 on the postback:

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    if(i != 4)//conditionally hide 5th item, 
    { //but BUG occurs on postback, all items after 5th will not be bound to the the list
      @Html.HiddenFor(m => m.Persons[i].PersonId)
      @Html.EditorFor(m => m.Persons[i].FirstName) 
      @Html.EditorFor(m => m.Persons[i].LastName)           
    }
}

Try this...

while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {

IE is even worse with 2 connection per domain limit. But I wouldn't rely on fixing client browsers. Even if you have control over them, browsers like chrome will auto update and a future release might behave differently than you expect. I'd focus on solving the problem within your system design.

Your choices are to:

1. Load the images in sequence so that only 1 or 2 XHR calls are active at a time (use the success event from the previous image to check if there are more images to download and start the next request).

2. Use sub-domains like serverA.myphotoserver.com and serverB.myphotoserver.com. Each sub domain will have its own pool for connection limits. This means you could have 2 requests going to 5 different sub-domains if you wanted to. The downfall is that the photos will be cached according to these sub-domains. BTW, these don't need to be "mirror" domains, you can just make additional DNS pointers to the exact same website/server. This means you don't have the headache of administrating many servers, just one server with many DNS records.

I feel like none of the answers really solve the issue. I think you need to tell the embedded server of Spring Boot what should be the maximum time to process a request. How exactly we do that is dependent on the type of the embedded server used.

In case of Undertow, one can do this:

@Component
class WebServerCustomizer : WebServerFactoryCustomizer<UndertowServletWebServerFactory> {
    override fun customize(factory: UndertowServletWebServerFactory) {
        factory.addBuilderCustomizers(UndertowBuilderCustomizer {
            it.setSocketOption(Options.READ_TIMEOUT, 5000)
            it.setSocketOption(Options.WRITE_TIMEOUT, 25000)
        })
    }
}

The solution to avoid the unchecked warning:

class MyMap extends HashMap<String, String> {};
someMap = (MyMap)getApplicationContext().getBean("someMap");

Mainly If you are using Linux Based system Like 'Ubuntu' and this is only suggested for localhost user not for the server.

Follow all the steps mentioned in the previous answers. +

Check in Apache configuration for it. (AllowOverride All) If AllowOverride value is none then change it to All and restart apache again.

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

Let me know if this step help anyone. As it can save you time if you find it earlier.

Images are for some user who understand easily from image the from the text:

Android Device Monitor was deprecated in Android Studio 3.1 and removed from Android Studio 3.2. To start the standalone Device Monitor application in Android Studio 3.1 and lower you can run android-sdk/tools/monitor.bat

Use ffmpeg or a similar tool to convert all of your MP3s into a consistent format, e.g.

ffmpeg -i originalA.mp3 -f mp3 -ab 128kb -ar 44100 -ac 2 intermediateA.mp3  
ffmpeg -i originalB.mp3 -f mp3 -ab 128kb -ar 44100 -ac 2 intermediateB.mp3

Then, at runtime, concat your files together:

cat intermediateA.mp3 intermediateB.mp3 > output.mp3

Finally, run them through the tool MP3Val to fix any stream errors without forcing a full re-encode:

mp3val output.mp3 -f -nb

In powershell you can to use severals commands, for looking for this commands digit: Get-Alias;

So the cammands the can to use are:

write-host (ls MydirectoryName).Count

or

write-host (dir MydirectoryName).Count

or

write-host (Get-ChildrenItem MydirectoryName).Count

Just use Hash.[] with the values in the array. For example:

arr = [1,2,3,4]
Hash[*arr] #=> gives {1 => 2, 3 => 4}

You just use the method

public Object put(Object key, Object value)

if the key was already present in the Map then the previous value is returned.

Try with this code:

from PIL import Image

Image.fromarray(image).show()

StringListName = ObjectListName.stream().map( m -> m.toString() ).collect( Collectors.toList() );

I defined my own two functions

• utc_time2datetime(utc_time, tz=None)
• datetime2utc_time(datetime)

here:

import time
import datetime
from pytz import timezone
import calendar
import pytz


def utc_time2datetime(utc_time, tz=None):
    # convert utc time to utc datetime
    utc_datetime = datetime.datetime.fromtimestamp(utc_time)

    # add time zone to utc datetime
    if tz is None:
        tz_datetime = utc_datetime.astimezone(timezone('utc'))
    else:
        tz_datetime = utc_datetime.astimezone(tz)

    return tz_datetime


def datetime2utc_time(datetime):
    # add utc time zone if no time zone is set
    if datetime.tzinfo is None:
        datetime = datetime.replace(tzinfo=timezone('utc'))

    # convert to utc time zone from whatever time zone the datetime is set to
    utc_datetime = datetime.astimezone(timezone('utc')).replace(tzinfo=None)

    # create a time tuple from datetime
    utc_timetuple = utc_datetime.timetuple()

    # create a time element from the tuple an add microseconds
    utc_time = calendar.timegm(utc_timetuple) + datetime.microsecond / 1E6

    return utc_time

In database design, iIhighly recommend using Unixtime for consistency and indexing / search / comparison performance.

UNIX_TIMESTAMP() 

One can always convert to human readable formats afterwards, internationalizing as is individually most convenient.

FROM_ UNIXTIME (unix_timestamp, [format ])

Bootstrap 3:

Why fight it? Why not simply control your table width using the bootstrap grid?

<div class="row">
    <div class="col-sm-6">
        <table></table>
    </div>
</div>

This will create a table that is half (6 out of 12) of the width of the containing element.

I sometimes use inline styles as per the other answers, but it is discouraged.

Bootstrap 4:

Bootstrap 4 has some nice helper classes for width like w-25, w-50, w-75, w-100, and w-auto. This will make the table 50% width:

<table class="w-50"></table>

Here's the doc: https://getbootstrap.com/docs/4.0/utilities/sizing/

var1 = var1 or 4

The only issue this might have is that if var1 is a falsey value, like False or 0 or [], it will choose 4 instead. That might be an issue.

You can also just search on sites like Tucows and CNET, they have it there too.

I dissent from both the answers. Don't create a reference at all, but use late binding:

  Dim objExcelApp As Object
  Dim wb As Object

  Sub Initialize()
    Set objExcelApp = CreateObject("Excel.Application")
  End Sub

  Sub ProcessDataWorkbook()
     Set wb = objExcelApp.Workbooks.Open("path to my workbook")
     Dim ws As Object
     Set ws = wb.Sheets(1)

     ws.Cells(1, 1).Value = "Hello"
     ws.Cells(1, 2).Value = "World"

     'Close the workbook
     wb.Close
     Set wb = Nothing
  End Sub

You will note that the only difference in the code above is that the variables are all declared as objects and you instantiate the Excel instance with CreateObject().

This code will run no matter what version of Excel is installed, while using a reference can easily cause your code to break if there's a different version of Excel installed, or if it's installed in a different location.

Also, the error handling could be added to the code above so that if the initial instantiation of the Excel instance fails (say, because Excel is not installed or not properly registered), your code can continue. With a reference set, your whole Access application will fail if Excel is not installed.

The problem is in your "this" value. Timer function cannot access the "state" prop because run in a different context. I suggest you to do something like this:

...
startTimer = () => {
  let interval = setInterval(this.timer.bind(this), 1000);
  this.setState({ interval });
};

As you can see I've added a "bind" method to your timer function. This allows the timer, when called, to access the same "this" of your react component (This is the primary problem/improvement when working with javascript in general).

Another option is to use another arrow function:

startTimer = () => {
  let interval = setInterval(() => this.timer(), 1000);
  this.setState({ interval });
};

One thing to note is that not all libraries will use the same meaning for pi, of course, so it never hurts to know what you're using. For example, the symbolic math library Sympy's representation of pi is not the same as math and numpy:

import math
import numpy
import scipy
import sympy

print(math.pi == numpy.pi)
> True
print(math.pi == scipy.pi)
> True
print(math.pi == sympy.pi)
> False

$(document).ready(function(){
    var response;
    $.validator.addMethod(
        "uniqueUserName", 
        function(value, element) {
            $.ajax({
                type: "POST",
                url: "http://"+location.host+"/checkUser.php",
                data: "checkUsername="+value,
                dataType:"html",
                success: function(msg)
                {
                    //If username exists, set response to true
                    response = ( msg == 'true' ) ? true : false;
                }
             });
            return response;
        },
        "Username is Already Taken"
    );

    $("#regFormPart1").validate({
        username: {
            required: true,
            minlength: 8,
            uniqueUserName: true
        },
        messages: {
            username: {
                required: "Username is required",
                minlength: "Username must be at least 8 characters",
                uniqueUserName: "This Username is taken already"
            }
        }
    });
});

I chose @nrodic's answer (thanks, by the way), but it has several drawbacks:

1) If you have rows containing "cat", "dog", "mouse", "cat dog", "cat dog mouse" (each on separate row), then when you search explicitly for "cat dog mouse", you'll be displayed "cat", "dog", "mouse", "cat dog", "cat dog mouse" rows.

2) .toLowerCase() was not implemented, that is, when you enter lower case string, rows with matching upper case text will not be showed.

So I came up with a fork of @nrodic's code, where

var data = this.value; //plain text, not an array

and

jo.filter(function (i, v) {
    var $t = $(this);
    var stringsFromRowNodes = $t.children("td:nth-child(n)")
    .text().toLowerCase();
    var searchText = data.toLowerCase();
    if (stringsFromRowNodes.contains(searchText)) {
        return true;
        }
    return false;
})
//show the rows that match.
.show();

Here goes the full code: http://jsfiddle.net/jumasheff/081qyf3s/

You will have to modify the below line:

<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>

modalRegister is the ID and hence requires a preceding # for ID reference in html.

So, the modified html code snippet would be as follows:

<li><a href="#" data-toggle="modal" data-target="#modalRegister">Register</a></li>

First Option:

OPEN package.json and add "--port port-no" in "serve" section.

Just like below, I have done it.

{
  "name": "app-name",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve --port 8090",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
}

Second Option: If You want through command prompt

npm run serve --port 8090

After setting the sort expression on the DefaultView (table.DefaultView.Sort = "Town ASC, Cutomer ASC" ) you should loop over the table using the DefaultView not the DataTable instance itself

foreach(DataRowView r in table.DefaultView)
{
    //... here you get the rows in sorted order
    Console.WriteLine(r["Town"].ToString());
}

Using the Select method of the DataTable instead, produces an array of DataRow. This array is sorted as from your request, not the DataTable

DataRow[] rowList = table.Select("", "Town ASC, Cutomer ASC");
foreach(DataRow r in rowList)
{
    Console.WriteLine(r["Town"].ToString());
}

An alternative to 'LOAD DATA' is available in which the data will not be moved from your existing source location to hive data warehouse location.

You can use ALTER TABLE command with 'LOCATION' option. Here is below required command

ALTER TABLE table_name ADD PARTITION (date_col='2017-02-07') LOCATION 'hdfs/path/to/location/'

The only condition here is, the location should be a directory instead of file.

Hope this will solve the problem.

This worked for me:

Remove-Item $folderPath -Force  -Recurse -ErrorAction SilentlyContinue

Thus the folder is removed with all files in there and it is not producing error if folder path doesn't exists.

To me this worked.

CREATE USER 'spowner'@'localhost' IDENTIFIED BY '1234'; 
GRANT ALL PRIVILEGES ON test.* To 'spowner'@'localhost'; 
FLUSH PRIVILEGES;

where

• spowner : user name
• 1234 : password of spowner
• test : database 'spowner' has access right to

Order is arbitrary, but there are several ways to sort them. One of them is as following:

#First, get the files:
import glob
import re
files =glob.glob1(img_folder,'*'+output_image_format)
# if you want sort files according to the digits included in the filename, you can do as following:
files = sorted(files, key=lambda x:float(re.findall("(\d+)",x)[0]))

Why not just have five separate images of a star (empty, quarter-full, half-full, three-quarter-full and full) then just inject the images into your DOM depending on the truncated or rouded value of rating multiplied by 4 (to get a whole numner for the quarters)?

For example, 4.8618164 multiplied by 4 and rounded is 19 which would be four and three quarter stars.

Alternatively (if you're lazy like me), just have one image selected from 21 (0 stars through 5 stars in one-quarter increments) and select the single image based on the aforementioned value. Then it's just one calculation followed by an image change in the DOM (rather than trying to change five different images).

Where the data returned is a string; you could cast to a different data type:

(from DataRow row in dataTable.Rows select row["columnName"].ToString()).ToList();

If you want to do something closer to console.log like replacing %s placeholders like in

>console.log("Hello %s how are you %s is everything %s?", "Loreto", "today", "allright")
>Hello Loreto how are you today is everything allright?

I wrote this

function log() {_x000D_
  var args = Array.prototype.slice.call(arguments);_x000D_
  var rep= args.slice(1, args.length);_x000D_
  var i=0;_x000D_
  var output = args[0].replace(/%s/g, function(match,idx) {_x000D_
    var subst=rep.slice(i, ++i);_x000D_
    return( subst );_x000D_
  });_x000D_
   return(output);_x000D_
}_x000D_
res=log("Hello %s how are you %s is everything %s?", "Loreto", "today", "allright");_x000D_
document.getElementById("console").innerHTML=res;

<span id="console"/>

you will get

>log("Hello %s how are you %s is everything %s?", "Loreto", "today", "allright")
>"Hello Loreto how are you today is everything allright?"

UPDATE

I have added a simple variant as String.prototype useful when dealing with string transformations, here is it:

String.prototype.log = function() {
    var args = Array.prototype.slice.call(arguments);
    var rep= args.slice(0, args.length);
    var i=0;
    var output = this.replace(/%s|%d|%f|%@/g, function(match,idx) {
      var subst=rep.slice(i, ++i);
      return( subst );
    });
    return output;
   }

In that case you will do

"Hello %s how are you %s is everything %s?".log("Loreto", "today", "allright")
"Hello Loreto how are you today is everything allright?"

Try this version here

If your script is called myScript.js and you want to pass the first and last name, 'Sean Worthington', as arguments like below:

node myScript.js Sean Worthington

Then within your script you write:

var firstName = process.argv[2]; // Will be set to 'Sean'
var lastName = process.argv[3]; // Will be set to 'Worthington'

It sounds like you're trying to use log4j from "both ends" (the consumer end and the configuration end).

If you want to code against the slf4j api but determine ahead of time (and programmatically) the configuration of the log4j Loggers that the classpath will return, you absolutely have to have some sort of logging adaptation which makes use of lazy construction.

public class YourLoggingWrapper {
    private static boolean loggingIsInitialized = false;

    public YourLoggingWrapper() {
        // ...blah
    }

    public static void debug(String debugMsg) {
        log(LogLevel.Debug, debugMsg);
    }

    // Same for all other log levels your want to handle.
    // You mentioned TRACE and ERROR.

    private static void log(LogLevel level, String logMsg) {
        if(!loggingIsInitialized)
            initLogging();

        org.slf4j.Logger slf4jLogger = org.slf4j.LoggerFactory.getLogger("DebugLogger");

        switch(level) {
        case: Debug:
            logger.debug(logMsg);
            break;
        default:
            // whatever
        }
    }

    // log4j logging is lazily constructed; it gets initialized
    // the first time the invoking app calls a log method
    private static void initLogging() {
        loggingIsInitialized = true;

        org.apache.log4j.Logger debugLogger = org.apache.log4j.LoggerFactory.getLogger("DebugLogger");

        // Now all the same configuration code that @oers suggested applies...
        // configure the logger, configure and add its appenders, etc.
        debugLogger.addAppender(someConfiguredFileAppender);
    }

With this approach, you don't need to worry about where/when your log4j loggers get configured. The first time the classpath asks for them, they get lazily constructed, passed back and made available via slf4j. Hope this helped!

Add this extension method to your code:

public static Uri UrlOriginal(this HttpRequestBase request)
{
  string hostHeader = request.Headers["host"];

  return new Uri(string.Format("{0}://{1}{2}",
     request.Url.Scheme, 
     hostHeader, 
     request.RawUrl));
}

And then you can execute it off the RequestContext.HttpContext.Request property.

There is a bug (can be side-stepped, see below) in Asp.Net that arises on machines that use ports other than port 80 for the local website (a big issue if internal web sites are published via load-balancing on virtual IP and ports are used internally for publishing rules) whereby Asp.Net will always add the port on the AbsoluteUri property - even if the original request does not use it.

This code ensures that the returned url is always equal to the Url the browser originally requested (including the port - as it would be included in the host header) before any load-balancing etc takes place.

At least, it does in our (rather convoluted!) environment :)

If there are any funky proxies in between that rewrite the host header, then this won't work either.

Update 30th July 2013

As mentioned by @KevinJones in comments below - the setting I mention in the next section has been documented here: http://msdn.microsoft.com/en-us/library/hh975440.aspx

Although I have to say I couldn't get it work when I tried it - but that could just be me making a typo or something.

Update 9th July 2012

I came across this a little while ago, and meant to update this answer, but never did. When an upvote just came in on this answer I thought I should do it now.

The 'bug' I mention in Asp.Net can be be controlled with an apparently undocumented appSettings value - called 'aspnet:UseHostHeaderForRequest' - i.e:

<appSettings>
  <add key="aspnet:UseHostHeaderForRequest" value="true" />
</appSettings>

I came across this while looking at HttpRequest.Url in ILSpy - indicated by the ---> on the left of the following copy/paste from that ILSpy view:

public Uri Url
{
  get
  {
    if (this._url == null && this._wr != null)
    {
      string text = this.QueryStringText;
      if (!string.IsNullOrEmpty(text))
      {
        text = "?" + HttpEncoder.CollapsePercentUFromStringInternal(text, 
          this.QueryStringEncoding);
      }
 ---> if (AppSettings.UseHostHeaderForRequestUrl)
      {
        string knownRequestHeader = this._wr.GetKnownRequestHeader(28);
        try
        {
          if (!string.IsNullOrEmpty(knownRequestHeader))
          {
            this._url = new Uri(string.Concat(new string[]
            {
              this._wr.GetProtocol(),
              "://",
              knownRequestHeader,
              this.Path,
              text 
            }));
          }
        }
        catch (UriFormatException)
        { }
     }
     if (this._url == null) { /* build from server name and port */
       ...

I personally haven't used it - it's undocumented and so therefore not guaranteed to stick around - however it might do the same thing that I mention above. To increase relevancy in search results - and to acknowledge somebody else who seeems to have discovered this - the 'aspnet:UseHostHeaderForRequest' setting has also been mentioned by Nick Aceves on Twitter

If #top and #bottom have fixed heights, you can use:

#top {
    position: absolute;
    top: 0;
    height: 200px;
}
#bottom {
    position: absolute;
    bottom: 0;
    height: 100px;
}
#central {
    margin-top: 200px;
    margin-bot: 100px;
}

update

If you want #central to stretch down, you could:

• Fake it with a background on parent;
• Use CSS3's (not widely supported, most likely) calc();
• Or maybe use javascript to dynamically add min-height.

With calc():

#central {
    min-height: calc(100% - 300px);
}

With jQuery it could be something like:

$(document).ready(function() {
  var desiredHeight = $("body").height() - $("top").height() - $("bot").height();
  $("#central").css("min-height", desiredHeight );
});

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

Not directly the requested answer, but maybe the root-cause of the question:

You can also prevent commands from even getting into the history, by prefixing them with a space character:

# This command will be in the history
echo Hello world

# This will not
 echo Hello world

We had the same error deploying a report to SSRS in our PROD environment. It was found the problem could even be reproduced with a “use ” statement. The solution was to re-sync the user's GUID account reference with the database in question (i.e., using "sp_change_users_login" like you would after restoring a db). A stock (cursor driven) script to re-sync all accounts is attached:

USE <your database>
GO

-------- Reset SQL user account guids ---------------------
DECLARE @UserName nvarchar(255) 
DECLARE orphanuser_cur cursor for 
      SELECT UserName = su.name 
      FROM sysusers su
      JOIN sys.server_principals sp ON sp.name = su.name
      WHERE issqluser = 1 AND
            (su.sid IS NOT NULL AND su.sid <> 0x0) AND
            suser_sname(su.sid) is null 
      ORDER BY su.name 

OPEN orphanuser_cur 
FETCH NEXT FROM orphanuser_cur INTO @UserName 

WHILE (@@fetch_status = 0)
BEGIN 
--PRINT @UserName + ' user name being resynced' 
exec sp_change_users_login 'Update_one', @UserName, @UserName 
FETCH NEXT FROM orphanuser_cur INTO @UserName 
END 

CLOSE orphanuser_cur 
DEALLOCATE orphanuser_cur

You can disable expandtab option from within Vim as below:

:set expandtab!

or

:set noet

PS: And set it back when you are done with inserting tab, with "set expandtab" or "set et"

PS: If you have tab set equivalent to 4 spaces in .vimrc (softtabstop), you may also like to set it to 8 spaces in order to be able to insert a tab by pressing tab key once instead of twice (set softtabstop=8).

I was looking for a solution for this and found this great article explaining the solution Relevant excerpt

My all-time-favorite use of ROWNUM is pagination. In this case, I use ROWNUM to get rows N through M of a result set. The general form is as follows:

select * enter code here
  from ( select /*+ FIRST_ROWS(n) */ 
  a.*, ROWNUM rnum 
      from ( your_query_goes_here, 
      with order by ) a 
      where ROWNUM <= 
      :MAX_ROW_TO_FETCH ) 
where rnum  >= :MIN_ROW_TO_FETCH;

Now with a real example (gets rows 148, 149 and 150):

select *
    from
  (select a.*, rownum rnum
     from
  (select id, data
     from t
   order by id, rowid) a
   where rownum <= 150
  )
   where rnum >= 148;

Assuming you are generating a shared library, most probably what happens is that the variant of liblog4cplus.a you are using wasn't compiled with -fPIC. In linux, you can confirm this by extracting the object files from the static library and checking their relocations:

ar -x liblog4cplus.a  
readelf --relocs fileappender.o | egrep '(GOT|PLT|JU?MP_SLOT)'

If the output is empty, then the static library is not position-independent and cannot be used to generate a shared object.

Since the static library contains object code which was already compiled, providing the -fPIC flag won't help.

You need to get ahold of a version of liblog4cplus.a compiled with -fPIC and use that one instead.

Put in a static extensions class file, the following:

public static string VersionedContent(this HttpContext httpContext, string virtualFilePath)
{
    var physicalFilePath = httpContext.Server.MapPath(virtualFilePath);
    if (httpContext.Cache[physicalFilePath] == null)
    {
        httpContext.Cache[physicalFilePath] = ((Page)httpContext.CurrentHandler).ResolveUrl(virtualFilePath) + (virtualFilePath.Contains("?") ? "&" : "?") + "v=" + File.GetLastWriteTime(physicalFilePath).ToString("yyyyMMddHHmmss");
    }
    return (string)httpContext.Cache[physicalFilePath];
}

And then call it in your Master Page as such:

In my case the problem was solved by Window -> Preferences -> Maven -> User Settings -> Update Settings. I don't know the problem cause at the first place.

The simple difference between document ready and page event in jQuery-mobile is that:

1. The document ready event is used for the whole HTML page,

   $(document).ready(function(e) {
       // Your code
   });
   

2. When there is a page event, use for handling particular page event:

   <div data-role="page" id="second">
       <div data-role="header">
           <h3>
               Page header
           </h3>
       </div>
       <div data-role="content">
           Page content
       </div> <!--content-->
       <div data-role="footer">
           Page footer
       </div> <!--footer-->
   </div><!--page-->
   

You can also use document for handling the pageinit event:

$(document).on('pageinit', "#mypage", function() {

});

The solution for the error is to add this line at the top of the code:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

UIImageView *imageView = [[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"MyImage.png"]]autorelease];

NSLog(@"Size of my Image => %f, %f ", [[imageView image] size].width, [[imageView image] size].height) ;

Click on settings in top tool bar;

Click on debugger;

In tree, highlight "gdb/cdb debugger" by clicking it

Click "create configuration"

Click default configuration, a dialogue will appear to the right for "executable path" with a button to the right.

Click on that button and it will bring up the file that codeblocks is installed in. Just keep clicking until you create the path to the gdb.exe (it sort of finds itself).

You can use this outside activities - all you need is to provide a Context:

LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );

Then to retrieve your different widgets, you inflate a layout:

View view = inflater.inflate( R.layout.myNewInflatedLayout, null );
Button myButton = (Button) view.findViewById( R.id.myButton );

EDIT as of July 2014

Davide's answer on how to get the LayoutInflater is actually more correct than mine (which is still valid though).

but select-String doesn't seem to have this option.

Correct. PowerShell is not a clone of *nix shells' toolset.

However it is not hard to build something like it yourself:

$regexes = Get-Content RegexFile.txt | 
           Foreach-Object { new-object System.Text.RegularExpressions.Regex $_ }

$fileList | Get-Content | Where-Object {
  foreach ($r in $regexes) {
    if ($r.IsMatch($_)) {
      $true
      break
    }
  }
  $false
}

As others stated, it's likely failing because the requested key doesn't exist in the array. I have a helper function here that takes the array, the suspected key, as well as a default return in the event the key does not exist.

    protected function _getArrayValue($array, $key, $default = null)
    {
        if (isset($array[$key])) return $array[$key];
        return $default;
    }

hope it helps.

class func uuid(completionHandler: @escaping (String) -> ()) {
    if let uuid = UIDevice.current.identifierForVendor?.uuidString {
        completionHandler(uuid)
    }
    else {

No, [^\x20-\x7E] is not ASCII.

This is real ASCII:

 [^\x00-\x7F]

Otherwise, it will trim out newlines and other special characters that are part of the ASCII table!

.ix indexer works okay for pandas version prior to 0.20.0, but since pandas 0.20.0, the .ix indexer is deprecated, so you should avoid using it. Instead, you can use .loc or iloc indexers. You can solve this problem by:

mask = df.my_channel > 20000
column_name = 'my_channel'
df.loc[mask, column_name] = 0

Or, in one line,

df.loc[df.my_channel > 20000, 'my_channel'] = 0

mask helps you to select the rows in which df.my_channel > 20000 is True, while df.loc[mask, column_name] = 0 sets the value 0 to the selected rows where maskholds in the column which name is column_name.

Update: In this case, you should use loc because if you use iloc, you will get a NotImplementedError telling you that iLocation based boolean indexing on an integer type is not available.

Note: this code resizes and removes everything outside the aspect ratio instead of padding it..

According to pip documentation example 3:

pip install --upgrade django

But based on my experience, using this method will also upgrade any package related to it. Example:

Assume you want to upgrade somepackage that require Django >= 1.2.4 using this kind of method it will also upgrade somepackage and django to the newest update. Just to be safe, do:

# Assume you want to keep Django 1.2.4
pip install --upgrade somepackage django==1.2.4

Doing this will upgrade somepackage and keeping Django to the 1.2.4 version.

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
    if (checkBoxImage.Checked)
    {
        groupBoxImage.Show();
    }
    else if (!checkBoxImage.Checked)
    {
        groupBoxImage.Hide(); 
    }
}

Use the "has attribute" selector:

$('p[MyTag]')

Or to select one where that attribute has a specific value:

$('p[MyTag="Sara"]')

There are other selectors for "attribute value starts with", "attribute value contains", etc.

If you don't want to use the PRI* macros, another approach for printing ANY integer type is to cast to intmax_t or uintmax_t and use "%jd" or %ju, respectively. This is especially useful for POSIX (or other OS) types that don't have PRI* macros defined, for instance off_t.

If you need to change the IDs occasionally, it's probably best not to use an identity column. In the past we've implemented autonumber fields manually using a 'Counters' table that tracks the next ID for each table. IIRC we did this because identity columns were causing database corruption in SQL2000 but being able to change IDs was occasionally useful for testing.

        $services = $this->Service->find('all', array(
            'limit' =>4,
            'fields' => array('Service.*','ServiceImage.*'),
            'joins' => array(
                array(
                        'table' => 'services_images',
                        'alias' => 'ServiceImage',
                        'type' => 'INNER',
                        'conditions' => array(
                        'ServiceImage.service_id' =>'Service.id'
                        )
                    ),
                ),
            )
        );

It goges to array is null.

The direct solution would be to invoke ifPresent(consumer) on the Optional returned by findFirst(). This consumer will be invoked when the optional is not empty. The benefit also is that it won't throw an exception if the find operation returned an empty optional, like your current code would do; instead, nothing will happen.

If you want to return the removed value, you can map the Optional to the result of calling remove:

producersProcedureActive.stream()
                        .filter(producer -> producer.getPod().equals(pod))
                        .findFirst()
                        .map(p -> {
                            producersProcedureActive.remove(p);
                            return p;
                        });

But note that the remove(Object) operation will again traverse the list to find the element to remove. If you have a list with random access, like an ArrayList, it would be better to make a Stream over the indexes of the list and find the first index matching the predicate:

IntStream.range(0, producersProcedureActive.size())
         .filter(i -> producersProcedureActive.get(i).getPod().equals(pod))
         .boxed()
         .findFirst()
         .map(i -> producersProcedureActive.remove((int) i));

With this solution, the remove(int) operation operates directly on the index.

I had to run the following command:

sudo apt-get autoremove phpmyadmin

Then I cleared my cache and it worked!

Swift 2.1

var array = ["0","1","2","3"]

if let index = array.indexOf("1") {
   array.removeAtIndex(index)
}

print(array) // ["0","2","3"]

Swift 3

var array = ["0","1","2","3"]

if let index = array.index(of: "1") {
    array.remove(at: index)
}
array.remove(at: 1)

Can I control the HTTP headers sent by window.open (cross browser)?

No

If not, can I somehow window.open a page that then issues my request with custom headers inside its popped-up window?

• You can request a URL that triggers a server side program which makes the request with arbitrary headers and then returns the response
• You can run JavaScript (probably saying goodbye to Progressive Enhancement) that uses XHR to make the request with arbitrary headers (assuming the URL fits within the Same Origin Policy) and then process the result in JS.

I need some cunning hacks...

It might help if you described the problem instead of asking if possible solutions would work.

Possibly the fastest solution is to operate in plain Python:

Series(
    map(
        '_'.join,
        df.values.tolist()
        # when non-string columns are present:
        # df.values.astype(str).tolist()
    ),
    index=df.index
)

Comparison against @MaxU answer (using the big data frame which has both numeric and string columns):

%timeit big['bar'].astype(str) + '_' + big['foo'] + '_' + big['new']
# 29.4 ms ± 1.08 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)


%timeit Series(map('_'.join, big.values.astype(str).tolist()), index=big.index)
# 27.4 ms ± 2.36 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Comparison against @derchambers answer (using their df data frame where all columns are strings):

from functools import reduce

def reduce_join(df, columns):
    slist = [df[x] for x in columns]
    return reduce(lambda x, y: x + '_' + y, slist[1:], slist[0])

def list_map(df, columns):
    return Series(
        map(
            '_'.join,
            df[columns].values.tolist()
        ),
        index=df.index
    )

%timeit df1 = reduce_join(df, list('1234'))
# 602 ms ± 39 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit df2 = list_map(df, list('1234'))
# 351 ms ± 12.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

iOS12 Swift 4 and Swift 5

If you just want to check the connection, and your lowest target is iOS12, then you can use NWPathMonitor

import Network

It needs a little setup with some properties.

let internetMonitor = NWPathMonitor()
let internetQueue = DispatchQueue(label: "InternetMonitor")
private var hasConnectionPath = false

I created a function to get it going. You can do this on view did load or anywhere else. I put a guard in so you can call it all you want to get it going.

func startInternetTracking() {
    // only fires once
    guard internetMonitor.pathUpdateHandler == nil else {
        return
    }
    internetMonitor.pathUpdateHandler = { update in
        if update.status == .satisfied {
            print("Internet connection on.")
            self.hasConnectionPath = true
        } else {
            print("no internet connection.")
            self.hasConnectionPath = false
        }
    }
    internetMonitor.start(queue: internetQueue)
}

/// will tell you if the device has an Internet connection
/// - Returns: true if there is some kind of connection
func hasInternet() -> Bool {
    return hasConnectionPath
}

Now you can just call the helper function hasInternet() to see if you have one. It updates in real time. See Apple documentation for NWPathMonitor. It has lots more functionality like cancel() if you need to stop tracking the connection, type of internet you are looking for, etc. https://developer.apple.com/documentation/network/nwpathmonitor

You don't need to convert it

switch(op)
{
     case Operator.PLUS:
     {
        // your code 
        // for plus operator
        break;
     }
     case Operator.MULTIPLY:
     {
        // your code 
        // for MULTIPLY operator
        break;
     }
     default: break;
}

By the way, use brackets

I used this code and it works just fine

const int margin = 5;
        Rectangle rect = new Rectangle(
            Screen.PrimaryScreen.WorkingArea.X + margin,
            Screen.PrimaryScreen.WorkingArea.Y + margin,
            Screen.PrimaryScreen.WorkingArea.Width - 2 * margin,
            Screen.PrimaryScreen.WorkingArea.Height - 2 * (margin - 7));
        this.Bounds = rect;

Here's what's actually happening localhost means that you want to open htdocs. First it will search for any file named index.php or index.html. If one of those exist it will open the file. If neither of those exist then it will open all folder/file inside htdocs directory which is what you want.

So, the simplest solution is to rename index.php or index.html to index2.php etc.

        var el = driver.findElement( webdriver.By.id( id ) );
        el.click();
        el.clear();
        el.sendKeys( value );
    });
},

Find the element, click it, clear it, then send the keys.

Since Java 1.5 you can use the String.format method. For example, to do the same thing as your example:

String format = String.format("%0%d", digits);
String result = String.format(format, num);
return result;

In this case, you're creating the format string using the width specified in digits, then applying it directly to the number. The format for this example is converted as follows:

%% --> %
0  --> 0
%d --> <value of digits>
d  --> d

So if digits is equal to 5, the format string becomes %05d which specifies an integer with a width of 5 printing leading zeroes. See the java docs for String.format for more information on the conversion specifiers.

For those who don't use jQuery, below is my vanilla JavaScript function to create a form data object that can be accessed like any common object, unlike new FormData(form).

You can also play around with it in this pen: http://codepen.io/thdoan/pen/EyawvR

UPDATE: I also added a function to populate the form with the object returned by formDataToObject().

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="https://www.yahoo.com/" selected>Option1</option>
    <option value="https://www.google.co.in/">Option2</option>
    <option value="https://www.gmail.com/">Option3</option>

</select>

And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){
        location.href=document.getElementById("selectbox").value;
    }       
</script>

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val(); 
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
    })
})

I just press enter and type Pause and it works fine

Have you copied classes12.jar in lib folder of your web application and set the classpath in eclipse.

Right-click project in Package explorer Build path -> Add external archives...

Select your ojdbc6.jar archive

Press OK

Or

Go through this link and read and do carefully.

The library should be now referenced in the "Referenced Librairies" under the Package explorer. Now try to run your program again.

The information schema views and pg_typeof() return incomplete type information. Of these answers, psql gives the most precise type information. (The OP might not need such precise information, but should know the limitations.)

create domain test_domain as varchar(15);

create table test (
  test_id test_domain, 
  test_vc varchar(15), 
  test_n numeric(15, 3), 
  big_n bigint,
  ip_addr inet
);

Using psql and \d public.test correctly shows the use of the data type test_domain, the length of varchar(n) columns, and the precision and scale of numeric(p, s) columns.

sandbox=# \d public.test
             Table "public.test"
 Column  |         Type          | Modifiers
---------+-----------------------+-----------
 test_id | test_domain           |
 test_vc | character varying(15) |
 test_n  | numeric(15,3)         |
 big_n   | bigint                |
 ip_addr | inet                  |

This query against an information_schema view does not show the use of test_domain at all. It also doesn't report the details of varchar(n) and numeric(p, s) columns.

select column_name, data_type 
from information_schema.columns 
where table_catalog = 'sandbox'
  and table_schema = 'public'
  and table_name = 'test';

 column_name |     data_type
-------------+-------------------
 test_id     | character varying
 test_vc     | character varying
 test_n      | numeric
 big_n       | bigint
 ip_addr     | inet

You might be able to get all that information by joining other information_schema views, or by querying the system tables directly. psql -E might help with that.

The function pg_typeof() correctly shows the use of test_domain, but doesn't report the details of varchar(n) and numeric(p, s) columns.

select pg_typeof(test_id) as test_id, 
       pg_typeof(test_vc) as test_vc,
       pg_typeof(test_n) as test_n,
       pg_typeof(big_n) as big_n,
       pg_typeof(ip_addr) as ip_addr
from test;

   test_id   |      test_vc      | test_n  | big_n  | ip_addr
-------------+-------------------+---------+--------+---------
 test_domain | character varying | numeric | bigint | inet

Complementing the coment of @Mark Baker.
Do as follow:

$titles = array('title 1', 'title 2');
$sheet = 0;
foreach($array as $value){
    if($sheet > 0){
        $objPHPExcel->createSheet();
        $sheet = $objPHPExcel->setActiveSheetIndex($sheet);
        $sheet->setTitle("$value");
        //Do you want something more here
    }else{
        $objPHPExcel->setActiveSheetIndex(0)->setTitle("$value");
    }
    $sheet++;
}  

This worked for me. And hope it works for those who need! :)

@klode's answer is right.

However, you are supposed to set another response header to make your header accessible to others.

Example:

First, you add 'page-size' in response header

response.set('page-size', 20);

Then, all you need to do is expose your header

response.set('Access-Control-Expose-Headers', 'page-size')

If you don't want to use a List, ArrayList, or other dynamically-sized collection and then convert to an array (that's the method I'd recommend, by the way), then you'll have to allocate the array to its maximum possible size, keep track of how many items you put in it, and then create a new array with just those items in it:

private Update BuildMetaData(MetaData[] nvPairs)
{
    Update update = new Update();
    InputProperty[] ip = new InputProperty[20];  // how to make this "dynamic"
    int i;
    for (i = 0; i < nvPairs.Length; i++)
    {
        if (nvPairs[i] == null) break;
        ip[i] = new InputProperty(); 
        ip[i].Name = "udf:" + nvPairs[i].Name;
        ip[i].Val = nvPairs[i].Value;
    }
    if (i < nvPairs.Length)
    {
        // Create new, smaller, array to hold the items we processed.
        update.Items = new InputProperty[i];
        Array.Copy(ip, update.Items, i);
    }
    else
    {
        update.Items = ip;
    }
    return update;
}

An alternate method would be to always assign update.Items = ip; and then resize if necessary:

update.Items = ip;
if (i < nvPairs.Length)
{
    Array.Resize(update.Items, i);
}

It's less code, but will likely end up doing the same amount of work (i.e. creating a new array and copying the old items).

As this question comes often, here is the simple explanation.

datetime or time module has two important functions.

• strftime - creates a string representation of date or time from a datetime or time object.
• strptime - creates a datetime or time object from a string.

In both cases, we need a formating string. It is the representation that tells how the date or time is formatted in your string.

Now lets assume we have a date object.

>>> from datetime import datetime
>>> d = datetime(2010, 2, 15)
>>> d
datetime.datetime(2010, 2, 15, 0, 0)

If we want to create a string from this date in the format 'Mon Feb 15 2010'

>>> s = d.strftime('%a %b %d %y')
>>> print s
Mon Feb 15 10

Lets assume we want to convert this s again to a datetime object.

>>> new_date = datetime.strptime(s, '%a %b %d %y')
>>> print new_date
2010-02-15 00:00:00

Refer This document all formatting directives regarding datetime.

In my case it happened for leaving some empty intent-filter inside the Activity tag

    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">

            <intent-filter>

            </intent-filter>

    </activity> 

So just removing them solved the problem.

    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
    </activity> 

just tested doing this and it seems to work in firefox & IE

<html>
    <head>
        <script type="text/javascript">
            function alertFilename()
            {
                var thefile = document.getElementById('thefile');
                alert(thefile.value);
            }
        </script>
    </head>
    <body>
        <form>
            <input type="file" id="thefile" onchange="alertFilename()" />
            <input type="button" onclick="alertFilename()" value="alert" />
        </form>
    </body>
</html>

Tested with: log4j-ap 2.13.2, log4j-core 2.13.2.

1. Keep XML file directly under below folder structure. src/main/java
2. In the POM:

    <build>   
 <resources>       
             <resource>
                <filtering>false</filtering>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>             
            </resource>
 </resources>  
</build>

3. Clean and build.

You have to use the android:hint attribute

<EditText
android:id="@+id/message"
android:hint="<<Your placeholder>>"
/>

In Android Studio, you can switch from XML -> Design View and click on the Component in the layout, the EditText field in this case. This will show all the applicable attributes for that GUI component. This will be handy when you don't know about all the attributes that are there.

You would be surprised to see that EditText has more than 140 attributes for customization.

The last answer worked for me for a few months, then stopped recognizing the filename, as adeneo commented ...

@Scott's answer here is working for me:

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

you can delete the objects directly from the admin panel or else there is also an option to delete specific or selected id from an interactive shell by typing in python3 manage.py shell (python3 in Linux). If you want the user to delete the objects through the browser (with provided visual interface) e.g. of an employee whose ID is 6 from the database, we can achieve this with the following code, emp = employee.objects.get(id=6).delete()

THIS WILL DELETE THE EMPLOYEE WITH THE ID is 6.

If you wish to delete the all of the employees exist in the DB instead of get(), specify all() as follows: employee.objects.all().delete()

On Servlet 3.0 or newer you could just specify

<web-app ...>
    <error-page>
        <location>/general-error.html</location>
    </error-page>
</web-app>

But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.

<error-page>
    <!-- Missing login -->
    <error-code>401</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Forbidden directory listing -->
    <error-code>403</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Missing resource -->
    <error-code>404</error-code>
    <location>/Error404.html</location>
</error-page>
<error-page>
    <!-- Uncaught exception -->
    <error-code>500</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Unsupported servlet method -->
    <error-code>503</error-code>
    <location>/general-error.html</location>
</error-page>

That should cover the most common ones.

You may also consider the following solution:

let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
    return html + "<li>" + item + "</li>";
        }, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;

The javadoc for Math.atan(double) is pretty clear that the returning value can range from -pi/2 to pi/2. So you need to compensate for that return value.

// not familiar with C#, but C#'s equivalent of PHP's:
$count = count($productIds); // where $productIds is the array you also use in IN (...)

SELECT IF ((SELECT COUNT(*) FROM Products WHERE ProductID IN (1, 10, 100)) = $count, 1, 0)

Dragon NaturallySpeaking seems to support MP3 input.

If you want an open source version (I think there are some Asterisk integration projects based on this one).

String.Trim() returns a string which equals the input string with all white-spaces trimmed from start and end:

"   A String   ".Trim() -> "A String"

String.TrimStart() returns a string with white-spaces trimmed from the start:

"   A String   ".TrimStart() -> "A String   "

String.TrimEnd() returns a string with white-spaces trimmed from the end:

"   A String   ".TrimEnd() -> "   A String"

None of the methods modify the original string object.

(In some implementations at least, if there are no white-spaces to be trimmed, you get back the same string object you started with:

csharp> string a = "a"; csharp> string trimmed = a.Trim(); csharp> (object) a == (object) trimmed; returns true

I don't know whether this is guaranteed by the language.)

You should escape the characters like double quotes in the html string by adding "\"

eg: <h2 class=\"fg-white\">

Similar to what Richard Detsch but with a bit easier to follow (works with packages as well)

Step 1: Unwrap the War file.

jar -xvf MyWar.war

Step 2: move into the directory

cd WEB-INF

Step 3: Run your main with all dependendecies

java -classpath "lib/*:classes/." my.packages.destination.FileToRun

I faced the same error while using pip on anaconda3 4.4.0 (python 3.6) on windows.

I fixed the problem by the following command:

easy_install pip==18.*  ### installing the latest version pip

Or if lower version pip required, mention the same in the command.

Or you can try installing the lower version and then upgrading the same to latest version as follow:

easy_install pip==9.0.1

easy_install --upgrade pip

Put your class name on the mat-form-field element. This works for all inputs.

As a brand new member, I was unable to simply add a comment on the post but I want to second that the solution offered by Phillip Schwartz worked for me. Hopefully people in a similar situation will try that path sooner with the emphasis. Not having page breaks was a frustrating problem for quite a while so I am grateful for the discussion above.

As Phillip Schwartz said: "You'll need to install wkhtmltopdf: [http://wkhtmltopdf.org/downloads.html][1]

and Nbconvert "

You then add a cell of the type "rawNBConvert" and include:

<p style="page-break-after:always;"></p>

That seemed to do the trick for me, and the generated PDF had the page break at the corresponding locations. You don't need to run the custom code though, as it seems the "normal" path of downloading the notebook as HTML, opening in browser, and printing to PDF works once those utilities are installed.

You can also run ->select('DISTINCT `field`', FALSE) and the second parameter tells CI not to escape the first argument.

With the second parameter as false, the output would be SELECT DISTINCT `field` instead of without the second parameter, SELECT `DISTINCT` `field`

No regexp, readable, and according to https://en.wikipedia.org/wiki/Comma-separated_values#Basic_rules:

function csv2arr(str: string) {
    let line = ["",];
    const ret = [line,];
    let quote = false;

    for (let i = 0; i < str.length; i++) {
        const cur = str[i];
        const next = str[i + 1];

        if (!quote) {
            const cellIsEmpty = line[line.length - 1].length === 0;
            if (cur === '"' && cellIsEmpty) quote = true;
            else if (cur === ",") line.push("");
            else if (cur === "\r" && next === "\n") { line = ["",]; ret.push(line); i++; }
            else if (cur === "\n" || cur === "\r") { line = ["",]; ret.push(line); }
            else line[line.length - 1] += cur;
        } else {
            if (cur === '"' && next === '"') { line[line.length - 1] += cur; i++; }
            else if (cur === '"') quote = false;
            else line[line.length - 1] += cur;
        }
    }
    return ret;
}

If you're just testing your APIs manually, we've found RestClient 2.3 or the Poster add-on for Firefox to be pretty helpful. Both of these let you build requests that GET, PUT, POST, or DELETE. You can save these requests to rerun later.

For simple automated testing try the Linux (or Cygwin) 'curl' command in a shell script.

From something more industrial strength you can move up to Apache JMeter. JMeter is great for load testing.

In my case it turned out to be commented out HTML in a master page!

Who knew that commented out HTML such as this were actually interpreted by ASP.NET!

I faced a similar problem yesterday. I wrote a method with Java generics in order to calculate the median value of every collection of Numbers; you can apply my method to collections of Doubles, Integers, Floats and returns a double. Please consider that my method creates another collection in order to not alter the original one. I provide also a test, have fun. ;-)

public static <T extends Number & Comparable<T>> double median(Collection<T> numbers){
    if(numbers.isEmpty()){
        throw new IllegalArgumentException("Cannot compute median on empty collection of numbers");
    }
    List<T> numbersList = new ArrayList<>(numbers);
    Collections.sort(numbersList);
    int middle = numbersList.size()/2;
    if(numbersList.size() % 2 == 0){
        return 0.5 * (numbersList.get(middle).doubleValue() + numbersList.get(middle-1).doubleValue());
    } else {
        return numbersList.get(middle).doubleValue();
    }

}

JUnit test code snippet:

/**
 * Test of median method, of class Utils.
 */
@Test
public void testMedian() {
    System.out.println("median");
    Double expResult = 3.0;
    Double result = Utils.median(Arrays.asList(3.0,2.0,1.0,9.0,13.0));
    assertEquals(expResult, result);
    expResult = 3.5;
    result = Utils.median(Arrays.asList(3.0,2.0,1.0,9.0,4.0,13.0));
    assertEquals(expResult, result);
}

Usage example (consider the class name is Utils):

List<Integer> intValues = ... //omitted init
Set<Float> floatValues = ... //omitted init
.....
double intListMedian = Utils.median(intValues);
double floatSetMedian = Utils.median(floatValues);

Note: my method works on collections, you can convert arrays of numbers to list of numbers as pointed here

I thought this might be useful to someone:

in chrome version 32, a 2-pixels border automatically appears around iframes without the seamless attribute. It can be easily removed by adding this CSS rule:

iframe:not([seamless]) { border:none; }

Chrome uses the same selector with these default user-agent styles:

iframe:not([seamless]) {
  border: 2px inset;
  border-image-source: initial;
  border-image-slice: initial;
  border-image-width: initial;
  border-image-outset: initial;
  border-image-repeat: initial;
}

When you’re faced with a problem to solve (and frankly, who isn’t these days?), the basic strategy usually taken by we computer people is called “divide and conquer.” It goes like this:

• Conceptualize the specific problem as a set of smaller sub-problems.
• Solve each smaller problem.
• Combine the results into a solution of the specific problem.

But “divide and conquer” is not the only possible strategy. We can also take a more generalist approach:

• Conceptualize the specific problem as a special case of a more general problem.
• Somehow solve the general problem.
• Adapt the solution of the general problem to the specific problem.

- Eric Lippert

I believe many solutions already exist for this problem in server-side languages such as ASP.Net/C#.

I've outlined some of the major aspects of the problem

• Issue: We need to load data only for the desired language

  Solution: For this purpose we save data to a separate files for each language

ex. res.de.js, res.fr.js, res.en.js, res.js(for default language)

• Issue: Resource files for each page should be separated so we only get the data we need

  Solution: We can use some tools that already exist like https://github.com/rgrove/lazyload

• Issue: We need a key/value pair structure to save our data

  Solution: I suggest a javascript object instead of string/string air. We can benefit from the intellisense from an IDE

• Issue: General members should be stored in a public file and all pages should access them

  Solution: For this purpose I make a folder in the root of web application called Global_Resources and a folder to store global file for each sub folders we named it 'Local_Resources'

• Issue: Each subsystems/subfolders/modules member should override the Global_Resources members on their scope

  Solution: I considered a file for each

Application Structure

root/
    Global_Resources/
        default.js
        default.fr.js
    UserManagementSystem/
        Local_Resources/
            default.js
            default.fr.js
            createUser.js
        Login.htm
        CreateUser.htm

The corresponding code for the files:

Global_Resources/default.js

var res = {
    Create : "Create",
    Update : "Save Changes",
    Delete : "Delete"
};

Global_Resources/default.fr.js

var res = {
    Create : "créer",
    Update : "Enregistrer les modifications",
    Delete : "effacer"
};

The resource file for the desired language should be loaded on the page selected from Global_Resource - This should be the first file that is loaded on all the pages.

UserManagementSystem/Local_Resources/default.js

res.Name = "Name";
res.UserName = "UserName";
res.Password = "Password";

UserManagementSystem/Local_Resources/default.fr.js

res.Name = "nom";
res.UserName = "Nom d'utilisateur";
res.Password = "Mot de passe";

UserManagementSystem/Local_Resources/createUser.js

// Override res.Create on Global_Resources/default.js
res.Create = "Create User"; 

UserManagementSystem/Local_Resources/createUser.fr.js

// Override Global_Resources/default.fr.js
res.Create = "Créer un utilisateur";

manager.js file (this file should be load last)

res.lang = "fr";

var globalResourcePath = "Global_Resources";
var resourceFiles = [];

var currentFile = globalResourcePath + "\\default" + res.lang + ".js" ;

if(!IsFileExist(currentFile))
    currentFile = globalResourcePath + "\\default.js" ;
if(!IsFileExist(currentFile)) throw new Exception("File Not Found");

resourceFiles.push(currentFile);

// Push parent folder on folder into folder
foreach(var folder in parent folder of current page)
{
    currentFile = folder + "\\Local_Resource\\default." + res.lang + ".js";

    if(!IsExist(currentFile))
        currentFile = folder + "\\Local_Resource\\default.js";
    if(!IsExist(currentFile)) throw new Exception("File Not Found");

    resourceFiles.push(currentFile);
}

for(int i = 0; i < resourceFiles.length; i++) { Load.js(resourceFiles[i]); }

// Get current page name
var pageNameWithoutExtension = "SomePage";

currentFile = currentPageFolderPath + pageNameWithoutExtension + res.lang + ".js" ;

if(!IsExist(currentFile))
    currentFile = currentPageFolderPath + pageNameWithoutExtension + ".js" ;
if(!IsExist(currentFile)) throw new Exception("File Not Found");

Hope it helps :)

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

In the following line.

temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

You are calling First but the collection returned from db.Responses.Where is empty.

Fortunately, jQuery selectors allow you much more freedom:

$("div a").click( function(event)
{
   var clicked = $(this); // jQuery wrapper for clicked element
   // ... click-specific code goes here ...
});

...will attach the specified callback to each <a> contained in a <div>.

I had the same problem, mine was a little different though I did not have a package name. My problem was the Class Path for example:

C:\Java Example>java -cp . HelloWorld 

The -cp option for Java and from what I can tell from my experience (not much) but I encountered the error about 20 times trying different methods and until I declared the class Path I was receiving the same error. Vishrant was correct in stating that . represents current directory.

If you need more information about the java options enter java -? or java -help I think the options are not optional.

I just did some more research I found a website that goes into detail about CLASSPATH. The CLASSPATH must be set as an environment variable; to the current directory <.>. You can set it from the command line in windows:

// Set CLASSPATH to the current directory '.'
prompt> set CLASSPATH=.

When you add a new environment setting you need to reboot before enabling the variable. But from the command prompt you can set it. It also can be set like I mentioned at the beginning. For more info, and if your using a different OS, check: Environment Variables.

Found it on another thread that solved my problem... was using an internet connection less network.

What are they?

Nothing special. Just as same as common Java Class Instance.

But those class are Synthetic proxy classes created by java.lang.reflect.Proxy#newProxyInstance

What is there relationship to the JVM? Are they JVM implementation specific?

Introduced in 1.3

http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection

It is a part of Java. so each JVM should support it.

How are they created (Openjdk7 source)?

In short : they are created using JVM ASM tech ( defining javabyte code at runtime )

something using same tech:

• asm( http://asm.ow2.org/ )
• cglib( http://cglib.sourceforge.net/ )

What happens after calling java.lang.reflect.Proxy#newProxyInstance

1. reading the source you can see newProxyInstance call getProxyClass0 to obtain a `Class

   `

2. after lots of cache or sth it calls the magic ProxyGenerator.generateProxyClass which return a byte[]
3. call ClassLoader define class to load the generated $Proxy Class (the classname you have seen)
4. just instance it and ready for use

What happens in magic sun.misc.ProxyGenerator

1. draw a class(bytecode) combining all methods in the interfaces into one

2. each method is build with same bytecode like

   1. get calling Method meth info (stored while generating)
   2. pass info into invocation handler's invoke()
   3. get return value from invocation handler's invoke()
   4. just return it

3. the class(bytecode) represent in form of byte[]

How to draw a class

Thinking your java codes are compiled into bytecodes, just do this at runtime

Talk is cheap show you the code

Use $dirty flag to show the error only after user interacted with the input:

<div>
  <input type="email" name="email" ng-model="user.email" required />
  <span ng-show="form.email.$dirty && form.email.$error.required">Email is required</span>
</div>

If you want to trigger the errors only after the user has submitted the form than you may use a separate flag variable as in:

<form ng-submit="submit()" name="form" ng-controller="MyCtrl">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="(form.email.$dirty || submitted) && form.email.$error.required">
      Email is required
    </span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  } 
};

Then, if all that JS inside ng-showexpression looks too much for you, you can abstract it into a separate method:

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  }

  $scope.hasError = function(field, validation){
    if(validation){
      return ($scope.form[field].$dirty && $scope.form[field].$error[validation]) || ($scope.submitted && $scope.form[field].$error[validation]);
    }
    return ($scope.form[field].$dirty && $scope.form[field].$invalid) || ($scope.submitted && $scope.form[field].$invalid);
  };

};

<form ng-submit="submit()" name="form">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="hasError('email', 'required')">required</span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

I did some work on this back when I was a researcher under Michael Stonebraker - you know, the professor who came up with Ingres, PostgreSQL, etc.

We realized that the fastest way was to first do a bounding box because it's SUPER fast. If it's outside the bounding box, it's outside. Otherwise, you do the harder work...

If you want a great algorithm, look to the open source project PostgreSQL source code for the geo work...

I want to point out, we never got any insight into right vs left handedness (also expressible as an "inside" vs "outside" problem...

UPDATE

BKB's link provided a good number of reasonable algorithms. I was working on Earth Science problems and therefore needed a solution that works in latitude/longitude, and it has the peculiar problem of handedness - is the area inside the smaller area or the bigger area? The answer is that the "direction" of the verticies matters - it's either left-handed or right handed and in this way you can indicate either area as "inside" any given polygon. As such, my work used solution three enumerated on that page.

In addition, my work used separate functions for "on the line" tests.

...Since someone asked: we figured out that bounding box tests were best when the number of verticies went beyond some number - do a very quick test before doing the longer test if necessary... A bounding box is created by simply taking the largest x, smallest x, largest y and smallest y and putting them together to make four points of a box...

Another tip for those that follow: we did all our more sophisticated and "light-dimming" computing in a grid space all in positive points on a plane and then re-projected back into "real" longitude/latitude, thus avoiding possible errors of wrapping around when one crossed line 180 of longitude and when handling polar regions. Worked great!

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

[amazonec2]
nginx.log.directory = /var/log/nginx
nginx.root.directory = /usr/share/nginx
nginx.conf.directory = /etc/nginx
nginx.run.directory  = /var/run
nginx.user           = nginx

[macports]
nginx.log.directory = /opt/local/var/log/nginx
nginx.root.directory = /opt/local/share/nginx
nginx.conf.directory = /opt/local/etc/nginx
nginx.run.directory  = /opt/local/var/run
nginx.user           = _www

Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:

str = str.replace(/[^-a-z0-9]+/g, "");

Also, if you need to match upper-case letters along with lower case, you should use:

str = str.replace(/[^-a-zA-Z0-9]+/g, "");

I think you can try "Google Grid Gallery", it based on aforementioned Masonry with some additions, like styles and viewer.

If you're constructing an array via mutability and then want to return an immutable version, you can simply return the mutable array as an "NSArray" via inheritance.

- (NSArray *)arrayOfStrings {
    NSMutableArray *mutableArray = [NSMutableArray array];
    mutableArray[0] = @"foo";
    mutableArray[1] = @"bar";

    return mutableArray;
}

If you "trust" the caller to treat the (technically still mutable) return object as an immutable NSArray, this is a cheaper option than [mutableArray copy].

Apple concurs:

To determine whether it can change a received object, the receiver of a message must rely on the formal type of the return value. If it receives, for example, an array object typed as immutable, it should not attempt to mutate it. It is not an acceptable programming practice to determine if an object is mutable based on its class membership.

The above practice is discussed in more detail here:

Best Practice: Return mutableArray.copy or mutableArray if return type is NSArray

Also: Psyco vs. C++.

It's still a bad comparison, since noone would do the numbercrunchy stuff benchmarks tend to focus on in pure Python anyway. A better one would be comparing the performance of realistic applications, or C++ versus NumPy, to get an idea whether your program will be noticeably slower.

There are many answers here already, but some have heavy upvotes and are incorrect.

The .NET Environment.ProcessorCount WILL return incorrect values and can fail critically if your system WMI is configured incorrectly.

If you want a RELIABLE way to count the cores, the only way is Win32 API.

Here is a C++ snippet:

#include <Windows.h>
#include <vector>

int num_physical_cores()
{
    static int num_cores = []
    {
        DWORD bytes = 0;
        GetLogicalProcessorInformation(nullptr, &bytes);
        std::vector<SYSTEM_LOGICAL_PROCESSOR_INFORMATION> coreInfo(bytes / sizeof(SYSTEM_LOGICAL_PROCESSOR_INFORMATION));
        GetLogicalProcessorInformation(coreInfo.data(), &bytes);

        int cores = 0;
        for (auto& info : coreInfo)
        {
            if (info.Relationship == RelationProcessorCore)
                ++cores;
        }
        return cores > 0 ? cores : 1;
    }();
    return num_cores;
}

And since this is a .NET C# Question, here's the ported version:

[StructLayout(LayoutKind.Sequential)]
struct CACHE_DESCRIPTOR
{
    public byte Level;
    public byte Associativity;
    public ushort LineSize;
    public uint Size;
    public uint Type;
}

    [FieldOffset(8)] private UInt64 Reserved2;
}

    RelationProcessorCore,
    RelationNumaNode,
    RelationCache,
    RelationProcessorPackage,

    RelationAll = 0xffff
}

struct SYSTEM_LOGICAL_PROCESSOR_INFORMATION

    public UIntPtr ProcessorMask;
    public LOGICAL_PROCESSOR_RELATIONSHIP Relationship;
    public SYSTEM_LOGICAL_PROCESSOR_INFORMATION_UNION ProcessorInformation;
}

[DllImport("kernel32.dll")]

static unsafe int GetProcessorCoreCount()
{
    GetLogicalProcessorInformation(null, out int bufferSize);
    int numEntries = bufferSize / sizeof(SYSTEM_LOGICAL_PROCESSOR_INFORMATION);
    var coreInfo = new SYSTEM_LOGICAL_PROCESSOR_INFORMATION[numEntries];

    fixed (SYSTEM_LOGICAL_PROCESSOR_INFORMATION* pCoreInfo = coreInfo)
    {
        GetLogicalProcessorInformation(pCoreInfo, out bufferSize);
        int cores = 0;
        for (int i = 0; i < numEntries; ++i)
        {
            ref SYSTEM_LOGICAL_PROCESSOR_INFORMATION info = ref pCoreInfo[i];
            if (info.Relationship == LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore)
                ++cores;
        }
        return cores > 0 ? cores : 1;
    }
}

public static readonly int NumPhysicalCores = GetProcessorCoreCount();

when you invoke a function , it is termed 'calling' a function . For eg , suppose you've defined a function that finds the average of two numbers like this-

def avgg(a,b) :
        return (a+b)/2;

now, to call the function , you do like this .

x=avgg(4,6)
print x

value of x will be 5 .

Simply you cant !! but you have some possbile options :

1- Excute php page as external page.

2- write your html code inside the php page itself.

3- use iframe to include the php within the html page.

to be more specific , unless you wanna edit your htaccess file , you may then consider this:

http://php.about.com/od/advancedphp/p/html_php.htm

If you have a return value you need to send to the UI you can use the generic version like this:

This is being called from an MVVM ViewModel in my case.

var updateManifest = Task<ShippingManifest>.Run(() =>
    {
        Thread.Sleep(5000);  // prove it's really working!

        // GenerateManifest calls service and returns 'ShippingManifest' object 
        return GenerateManifest();  
    })

    .ContinueWith(manifest =>
    {
        // MVVM property
        this.ShippingManifest = manifest.Result;

        // or if you are not using MVVM...
        // txtShippingManifest.Text = manifest.Result.ToString();    

        System.Diagnostics.Debug.WriteLine("UI manifest updated - " + DateTime.Now);

    }, TaskScheduler.FromCurrentSynchronizationContext());

Here is an updated answer for iOS7+. It uses NSURLSession, the new hotness. Disclaimer, this is untested and was written in a text field:

- (void)post {
    NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:nil];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://example.com/dontposthere"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    // Uncomment the following two lines if you're using JSON like I imagine many people are (the person who is asking specified plain text)
    // [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    // [request addValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
    [request setHTTPMethod:@"POST"];
    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    }];
    [postDataTask resume];
}

-(void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(    NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler {
    completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]);
}

Or better yet, use AFNetworking 2.0+. Usually I would subclass AFHTTPSessionManager, but I'm putting this all in one method to have a concise example.

- (void)post {
    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:@"https://example.com"]];
    // Many people will probably want [AFJSONRequestSerializer serializer];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    // Many people will probably want [AFJSONResponseSerializer serializer];
    manager.responseSerializer = [AFHTTPRequestSerializer serializer];
    manager.securityPolicy.allowInvalidCertificates = NO; // Some servers require this to be YES, but default is NO.
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"username" password:@"password"];
    [[manager POST:@"dontposthere" parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        NSString *responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"darn it");
    }] resume];
}

If you are using the JSON response serializer, the responseObject will be object from the JSON response (often NSDictionary or NSArray).

For CURLOPT_POSTFIELDS, the parameters can either be passed as a urlencoded string like para1=val1&para2=val2&.. or as an array with the field name as key and field data as value

Try the following format :

$data = json_encode(array(
"first"  => "John",
"last" => "Smith"
));

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$output = curl_exec($ch);
curl_close($ch);

Have you tried something like this? Put it in the head for it to work properly.

<script type="text/javascript">
    document.addEventListener("DOMContentLoaded", function(){
         //using DOMContentLoaded is good as it relies on the DOM being ready for
         //manipulation, rather than the windows being fully loaded. Just like
         //how jQuery's $(document).ready() does it.

         //loop through your inputs and set their values here
    }, false);
</script>

I use apache commons

String decodedUrl = new URLCodec().decode(url);

The default charset is UTF-8

Emoji support for application having tech stack - mysql, java, springboot, hibernate

Apply below changes in mysql for unicode support.

1. ALTER DATABASE <database-name> CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
2. ALTER TABLE <table-name> CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

DB Connection - jdbc url change:

jdbc:mysql://localhost:3306/<database-name>?useUnicode=yes&characterEncoding=UTF-8

Note - If the above step is not working please update mysql-connector version to 8.0.15. (mysql 5.7 works with connector version 8.0.15 for unicode support)

My favorite:

df = df.iloc[0:0]

But be aware df.index.max() will be nan. To add items I use:

df.loc[0 if math.isnan(df.index.max()) else df.index.max() + 1] = data

Try this:

X (\(Y\))? Z

Working example with strtoul will be:

#include <cstdlib>
#include <iostream>
using namespace std;

int main() { 
    string s = "fffefffe";
    char * p;
    long n = strtoul( s.c_str(), & p, 16 ); 
    if ( * p != 0 ) {  
        cout << "not a number" << endl;
    }    else {  
        cout << n << endl;
    }
}

strtol converts string to long. On my computer numeric_limits<long>::max() gives 0x7fffffff. Obviously that 0xfffefffe is greater than 0x7fffffff. So strtol returns MAX_LONG instead of wanted value. strtoul converts string to unsigned long that's why no overflow in this case.

Ok, strtol is considering input string not as 32-bit signed integer before convertation. Funny sample with strtol:

#include <cstdlib>
#include <iostream>
using namespace std;

int main() { 
    string s = "-0x10002";
    char * p;
    long n = strtol( s.c_str(), & p, 16 ); 
    if ( * p != 0 ) {  
        cout << "not a number" << endl;
    }    else {  
        cout << n << endl;
    }
}

The code above prints -65538 in console.

function isAPrimeNumber(num){
     var counter = 0;
     //loop will go k equals to $num
     for (k = 1; k <= num; k++) {
      //check if the num is divisible by itself and 1
      // `%` modulus gives the reminder of the value, so if it gives the reminder `0` then it is divisible by the value
       if (num % k == 0) {
         //increment counter value 1
         counter  = counter  + 1;
        }
    }
   //if the value of the `counter is 2` then it is a `prime number`
  //A prime number is exactly divisible by 2 times only (itself and 1)
   if (counter == 2) {
     return num + ' is a Prime Number';
   }else{
    return num + ' is nota Prime Number';
   }
 }

Now call isAPrimeNumber() function by passing a value.

var resp = isAPrimeNumber(5);
console.log(resp);

Output:

5 is a Prime Number

Notes:

• xiaobai's answer is simpler (git1.7.6+): git status --ignored
  (as detailed in "Is there a way to tell git-status to ignore the effects of .gitignore files?")
• MattDiPasquale's answer (to be upvoted) git clean -ndX works on older gits, displaying a preview of what ignored files could be removed (without removing anything)

Also interesting (mentioned in qwertymk's answer), you can also use the git check-ignore -v command, at least on Unix (doesn't work in a CMD Windows session)

git check-ignore *
git check-ignore -v *

The second one displays the actual rule of the .gitignore which makes a file to be ignored in your git repo.
On Unix, using "What expands to all files in current directory recursively?" and a bash4+:

git check-ignore **/*

(or a find -exec command)

Note: https://stackoverflow.com/users/351947/Rafi B. suggests in the comments to avoid the (risky) globstar:

git check-ignore -v $(find . -type f -print)

Make sure to exclude the files from the .git/ subfolder though.

Original answer 42009)

git ls-files -i

should work, except its source code indicates:

if (show_ignored && !exc_given) {
                fprintf(stderr, "%s: --ignored needs some exclude pattern\n",
                        argv[0]);

exc_given ?

It turns out it need one more parameter after the -i to actually list anything:

Try:

git ls-files -i --exclude-from=[Path_To_Your_Global].gitignore

(but that would only list your cached (non-ignored) object, with a filter, so that is not quite what you want)

Example:

$ cat .git/ignore
# ignore objects and archives, anywhere in the tree.
*.[oa]
$ cat Documentation/.gitignore
# ignore generated html files,
*.html
# except foo.html which is maintained by hand
!foo.html
$ git ls-files --ignored \
    --exclude='Documentation/*.[0-9]' \
    --exclude-from=.git/ignore \
    --exclude-per-directory=.gitignore

Actually, in my 'gitignore' file (called 'exclude'), I find a command line that could help you:

F:\prog\git\test\.git\info>type exclude
# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of
# exclude patterns (uncomment them if you want to use them):
# *.[oa]
# *~

So....

git ls-files --ignored --exclude-from=.git/info/exclude
git ls-files -i --exclude-from=.git/info/exclude

git ls-files --others --ignored --exclude-standard
git ls-files -o -i --exclude-standard

should do the trick.

(Thanks to honzajde pointing out in the comments that git ls-files -o -i --exclude-from... does not include cached files: only git ls-files -i --exclude-from... (without -o) does.)

As mentioned in the ls-files man page, --others is the important part, in order to show you non-cached, non-committed, normally-ignored files.

--exclude_standard is not just a shortcut, but a way to include all standard "ignored patterns" settings.

exclude-standard
Add the standard git exclusions: .git/info/exclude, .gitignore in each directory, and the user's global exclusion file.

I have a sequence function like this (which is completely general):

    public static IEnumerable<T> SelectAllRecursively<T>(this IEnumerable<T> items, Func<T, IEnumerable<T>> func)
    {
        return (items ?? Enumerable.Empty<T>()).SelectMany(o => new[] { o }.Concat(SelectAllRecursively(func(o), func)));
    }

Getting immediate children:

    public static IEnumerable<DependencyObject> FindChildren(this DependencyObject obj)
    {
        return Enumerable.Range(0, VisualTreeHelper.GetChildrenCount(obj))
            .Select(i => VisualTreeHelper.GetChild(obj, i));
    }

Finding all children down the hiararchical tree:

    public static IEnumerable<DependencyObject> FindAllChildren(this DependencyObject obj)
    {
        return obj.FindChildren().SelectAllRecursively(o => o.FindChildren());
    }

You can call this on the Window to get all controls.

After you have the collection, you can use LINQ (i.e. OfType, Where).

FWIW, I got this error when I was implementing core data in to an existing project. It turned out I forgot to link CoreData.h to my project. I had already added the CoreData framework to my project but solved the issue by linking to the framework in my pre-compiled header just like Apple's templates do:

#import <Availability.h>

#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import <CoreData/CoreData.h>
#endif

1.Update Master first...

git checkout [master branch]
git pull [master branch]

2.Now rebase source-branch with master branch

git checkout [source branch]
git rebase [master branch]
git pull [source branch] (remote/source branch)
git push [source branch]

IF source branch does not yet exist on remote then do:

git push -u origin [source branch]

"et voila..."

If you're used to ant then you could try the same with Gradle too:

task bundlemyjava{
    ant.jar(destfile: "build/cookmyjar.jar"){
        fileset(dir:"path to your source", includes:'**/*.class,*.class', excludes:'if any')
        } 
}

It looks like you can download just the grid now on Bootstrap 4s new download features.

HTML 5 with Webforms 2 provides an <input type="range"> which will make the browser generate a native slider for you. Unfortunately all browsers doesn't have support for this, however google has implemented all Webforms 2 controls with js. IIRC the js is intelligent enough to know if the browser has implemented the control, and triggers only if there is no native implementation.

From my point of view it should be considered best practice to use the browsers native controls when possible.

Like this ..

MsgBox(format(dt,"dd/MM/yyyy"))

The two calls have different meanings that have nothing to do with performance; the fact that it speeds up the execution time is (or might be) just a side effect. You should understand what each of them does and not blindly include them in every program because they look like an optimization.

ios_base::sync_with_stdio(false);

This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++-style I/O and get sensible and expected results. If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++-style I/O an adventure.

Also keep in mind that synchronized C++ streams are thread-safe (output from different threads may interleave, but you get no data races).

cin.tie(NULL);

This unties cin from cout. Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.

By default cin is tied to cout to ensure a sensible user interaction. For example:

std::cout << "Enter name:";
std::cin >> name;

If cin and cout are tied, you can expect the output to be flushed (i.e., visible on the console) before the program prompts input from the user. If you untie the streams, the program might block waiting for the user to enter their name but the "Enter name" message is not yet visible (because cout is buffered by default, output is flushed/displayed on the console only on demand or when the buffer is full).

So if you untie cin from cout, you must make sure to flush cout manually every time you want to display something before expecting input on cin.

In conclusion, know what each of them does, understand the consequences, and then decide if you really want or need the possible side effect of speed improvement.

Check out this great blog post by John Atten: ASP.NET Identity 2.0: Customizing Users and Roles

It has great step-by-step info on the whole process. Go read it : )

Here are some of the basics.

Extend the default ApplicationUser class by adding new properties (i.e.- Address, City, State, etc.):

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> 
    GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var userIdentity = await manager.CreateIdentityAsync(this,  DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

    // Use a sensible display name for views:
    [Display(Name = "Postal Code")]
    public string PostalCode { get; set; }

    // Concatenate the address info for display in tables and such:
    public string DisplayAddress
    {
        get
        {
            string dspAddress = string.IsNullOrWhiteSpace(this.Address) ? "" : this.Address;
            string dspCity = string.IsNullOrWhiteSpace(this.City) ? "" : this.City;
            string dspState = string.IsNullOrWhiteSpace(this.State) ? "" : this.State;
            string dspPostalCode = string.IsNullOrWhiteSpace(this.PostalCode) ? "" : this.PostalCode;

            return string.Format("{0} {1} {2} {3}", dspAddress, dspCity, dspState, dspPostalCode);
        }
    }

Then you add your new properties to your RegisterViewModel.

    // Add the new address properties:
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

Then update the Register View to include the new properties.

    <div class="form-group">
        @Html.LabelFor(m => m.Address, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Address, new { @class = "form-control" })
        </div>
    </div>

Then update the Register() method on AccountController with the new properties.

    // Add the Address properties:
    user.Address = model.Address;
    user.City = model.City;
    user.State = model.State;
    user.PostalCode = model.PostalCode;

Javascript is single-threaded, so by nature there should not be a sleep function because sleeping will block the thread. setTimeout is a way to get around this by posting an event to the queue to be executed later without blocking the thread. But if you want a true sleep function, you can write something like this:

function sleep(miliseconds) {
   var currentTime = new Date().getTime();

   while (currentTime + miliseconds >= new Date().getTime()) {
   }
}

Note: The above code is NOT recommended.

Take a look at this for more detail. It refers to how Apache handles multiple requests. Preforking, which is the default, starts a number of Apache processes (2 by default here, though I believe one can configure this through httpd.conf). Worker MPM will start a new thread per request, which I would guess, is more memory efficient. Historically, Apache has used prefork, so it's a better-tested model. Threading was only added in 2.0.

If you want authentication try domainname\administrator as the username.

If you don't want authentication then remove all the tickboxes in the authenticated access section of the direcory security > edit window.

There are some funnies restoring old databases into SQL 2008 via the guy; have you tried doing it via TSQL ?

Use Master
Go
RESTORE DATABASE YourDB
FROM DISK = 'C:\YourBackUpFile.bak'
WITH MOVE 'YourMDFLogicalName' TO 'D:\Data\YourMDFFile.mdf',--check and adjust path
MOVE 'YourLDFLogicalName' TO 'D:\Data\YourLDFFile.ldf' 

Jonathan's answer didn't seem to work for me. I'm using React v0.14.0 and React Router v1.0.0-rc3. This did:

<IndexRoute component={Home}/>.

So in Matthew's Case, I believe he'd want:

<IndexRoute component={SearchDashboard}/>.

It appears that the :include functionality was changed with Rails 2.1. Rails used to do the join in all cases, but for performance reasons it was changed to use multiple queries in some circumstances. This blog post by Fabio Akita has some good information on the change (see the section entitled "Optimized Eager Loading").

You're close; you should use dot notation in your use of the $ update operator to do that:

Person.update({'items.id': 2}, {'$set': {
    'items.$.name': 'updated item2',
    'items.$.value': 'two updated'
}}, function(err) { ...

A SqlDataAdapter is typically used to fill a DataSet or DataTable and so you will have access to the data after your connection has been closed (disconnected access).

The SqlDataReader is a fast forward-only and connected cursor which tends to be generally quicker than filling a DataSet/DataTable.

Furthermore, with a SqlDataReader, you deal with your data one record at a time, and don't hold any data in memory. Obviously with a DataTable or DataSet, you do have a memory allocation overhead.

If you don't need to keep your data in memory, so for rendering stuff only, go for the SqlDataReader. If you want to deal with your data in a disconnected fashion choose the DataAdapter to fill either a DataSet or DataTable.

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.
