Hi we can extract the pdf files using Apache Tika

The Example is :

import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;

import org.apache.tika.metadata.TikaCoreProperties;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.sax.BodyContentHandler;

public class WebPagePdfExtractor {

    public Map<String, Object> processRecord(String url) {
        DefaultHttpClient httpclient = new DefaultHttpClient();
        Map<String, Object> map = new HashMap<String, Object>();
        try {
            HttpGet httpGet = new HttpGet(url);
            HttpResponse response = httpclient.execute(httpGet);
            HttpEntity entity = response.getEntity();
            InputStream input = null;
            if (entity != null) {
                try {
                    input = entity.getContent();

                    ParseContext parseContext = new ParseContext();
                    parser.parse(input, handler, metadata, parseContext);
                    map.put("text", handler.toString().replaceAll("\n|\r|\t", " "));
                    map.put("title", metadata.get(TikaCoreProperties.TITLE));
                    map.put("pageCount", metadata.get("xmpTPg:NPages"));
                    map.put("status_code", response.getStatusLine().getStatusCode() + "");
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    if (input != null) {
                        try {
                            input.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        } catch (Exception exception) {
            exception.printStackTrace();
        }
        return map;
    }

    public static void main(String arg[]) {
        WebPagePdfExtractor webPagePdfExtractor = new WebPagePdfExtractor();
        Map<String, Object> extractedMap = webPagePdfExtractor.processRecord("http://math.about.com/library/q20.pdf");
        System.out.println(extractedMap.get("text"));
    }

}

Try this:

Xvfb --help

+extension name        Enable extension
-extension name        Disable extension

As per George Jempty's request to have the algorithm account for ties, I propose a modified version of Matthew Flaschen's algorithm.

function modeString(array) {
  if (array.length == 0) return null;

  var modeMap = {},
    maxEl = array[0],
    maxCount = 1;

  for (var i = 0; i < array.length; i++) {
    var el = array[i];

    if (modeMap[el] == null) modeMap[el] = 1;
    else modeMap[el]++;

    if (modeMap[el] > maxCount) {
      maxEl = el;
      maxCount = modeMap[el];
    } else if (modeMap[el] == maxCount) {
      maxEl += "&" + el;
      maxCount = modeMap[el];
    }
  }
  return maxEl;
}

This will now return a string with the mode element(s) delimited by a & symbol. When the result is received it can be split on that & element and you have your mode(s).

Another option would be to return an array of mode element(s) like so:

function modeArray(array) {
  if (array.length == 0) return null;
  var modeMap = {},
    maxCount = 1,
    modes = [];

  for (var i = 0; i < array.length; i++) {
    var el = array[i];

    if (modeMap[el] == null) modeMap[el] = 1;
    else modeMap[el]++;

    if (modeMap[el] > maxCount) {
      modes = [el];
      maxCount = modeMap[el];
    } else if (modeMap[el] == maxCount) {
      modes.push(el);
      maxCount = modeMap[el];
    }
  }
  return modes;
}

In the above example you would then be able to handle the result of the function as an array of modes.

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

http://plnkr.co/edit/k9qSx15fhSZRMwgAIMP4?p=preview

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

This error can happen if you instantiate a class that relies on that table, for example in views.py.

FLAG_ACTIVITY_NEW_TASK is the problem here which initiates a new task .Just remove it & you are done.

Well I recommend you to read what every Flag does before working with them

Diagnose

If you have pip installed (you should have it until you use Python 3.5), list the installed Python packages, like this:

$ pip list | grep -i keras
Keras (1.1.0)

If you don’t see Keras, it means that the previous installation failed or is incomplete (this lib has this dependancies: numpy (1.11.2), PyYAML (3.12), scipy (0.18.1), six (1.10.0), and Theano (0.8.2).)

Consult the pip.log to see what’s wrong.

You can also display your Python path like this:

$ python3 -c 'import sys, pprint; pprint.pprint(sys.path)'
['',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python35.zip',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages']

Make sure the Keras library appears in the /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages path (the path is different on Ubuntu).

If not, try do uninstall it, and retry installation:

$ pip uninstall Keras

Use a virtualenv

It’s a bad idea to use and pollute your system-wide Python. I recommend using a virtualenv (see this guide).

The best usage is to create a virtualenv directory (in your home, for instance), and store your virtualenvs in:

cd virtualenv/
virtualenv -p python3.5 py-keras
source py-keras/bin/activate
pip install -q -U pip setuptools wheel

Then install Keras:

pip install keras

You get:

$ pip list
Keras (1.1.0)
numpy (1.11.2)
pip (8.1.2)
PyYAML (3.12)
scipy (0.18.1)
setuptools (28.3.0)
six (1.10.0)
Theano (0.8.2)
wheel (0.30.0a0)

But, you also need to install extra libraries, like Tensorflow:

$ python -c "import keras"
Using TensorFlow backend.
Traceback (most recent call last):
  ...
ImportError: No module named 'tensorflow'

The installation guide of TesnsorFlow is here: https://www.tensorflow.org/versions/r0.11/get_started/os_setup.html#pip-installation

I was getting an "authenticationrequired" (407) error when clicking the [Sync] button (using the MS Git Provider), and this worked for me (VS 2013):

..\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe.config

  <system.net>
    <defaultProxy useDefaultCredentials="true" enabled="true">
      <proxy proxyaddress="http://username:password@proxyip:port" />
    </defaultProxy>
    <settings>
      <ipv6 enabled="false"/>
      <servicePointManager expect100Continue="false"/>
    </settings>
  </system.net>

I think the magic for me was setting 'ipv6' to 'false' - not sure why (perhaps only IPv4 is supported in my case). I tried other ways as shown above, but I move the "settings" section AFTER "defaultProxy", and changed "ipv6", and it worked perfectly with my login added (every other way I tried in all other answers posted just failed for me).

Edit: Just found another work around (without changing the config file). For some reason, if I disable the windows proxy (it's a URL to a PAC file in my case), try again (it will fail), and re-enable the proxy, it works. Seems to cache something internally that gets reset when I do this (at least in my case).

See:- ConnectionStrings content on this subject. There is no default command timeout property.

As RGML say, you can create an InfoPlist.strings, localize it then add your key and the value like this: "NSLocationWhenInUseUsageDescription" = "Help To locate me!";

It will add the key to your info.plist for the specified language.

Just like normal background-color: #f0f

You just need a way to target it, eg: <option id="myPinkOption">blah</option>

You can find the full list here.

• \t Insert a tab in the text at this point.
• \b Insert a backspace in the text at this point.
• \n Insert a newline in the text at this point.
• \r Insert a carriage return in the text at this point.
• \f Insert a formfeed in the text at this point.
• \' Insert a single quote character in the text at this point.
• \" Insert a double quote character in the text at this point.
• \\ Insert a backslash character in the text at this point.

Suppose you have defined your route name like this:

https://localhost:3000/user/:userid

which will become:

https://localhost:3000/user/5896544

Here, if you will print: request.params

{
userId : 5896544
}

so

request.params.userId = 5896544

so request.params is an object containing properties to the named route

and request.query comes from query parameters in the URL eg:

https://localhost:3000/user?userId=5896544 

request.query

{

userId: 5896544

}

so

request.query.userId = 5896544

Remember that MySQL keeps a simple index on a column after deleting foreign key. So, if you need to change 'references' column you should do it in 3 steps

• drop original FK
• drop an index (names as previous fk, using drop index clause)
• create new FK

The main reason for primary and foreign keys is to enforce data consistency.

A primary key enforces the consistency of uniqueness of values over one or more columns. If an ID column has a primary key then it is impossible to have two rows with the same ID value. Without that primary key, many rows could have the same ID value and you wouldn't be able to distinguish between them based on the ID value alone.

A foreign key enforces the consistency of data that points elsewhere. It ensures that the data which is pointed to actually exists. In a typical parent-child relationship, a foreign key ensures that every child always points at a parent and that the parent actually exists. Without the foreign key you could have "orphaned" children that point at a parent that doesn't exist.

You can use jquery for create element on the fly

$('#form').append('<input type="hidden" name="fieldname" value="fieldvalue" />');

or other way

$('<input>').attr({
    type: 'hidden',
    id: 'fieldId',
    name: 'fieldname'
}).appendTo('form')

You just forgot the quotes. Change your code according to this:

    <button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px'">Click Me!</button>

should work.

I've tested this:

When I open an Excel document D:\db\tmp\test1.xlsm:

• CurDir() returns C:\Users\[username]\Documents

• ActiveWorkbook.Path returns D:\db\tmp

So CurDir() has a system default and can be changed.

ActiveWorkbook.Path does not change for the same saved Workbook.

For example, CurDir() changes when you do "File/Save As" command, and select a random directory in the File/Directory selection dialog. Then click on Cancel to skip saving. But CurDir() has already changed to the last selected directory.

Your example is perfect: the field is private and it has a getter. This is the normal way to access a field. If you need a direct access to an object field, use reflection. Using reflection to get a field's value is a hack and should be used in extreme cases such as using a library whose code you cannot change.

Swift with @propertyWrapper

Save Codable object to UserDefault

@propertyWrapper
    struct UserDefault<T: Codable> {
        let key: String
        let defaultValue: T

        init(_ key: String, defaultValue: T) {
            self.key = key
            self.defaultValue = defaultValue
        }

        var wrappedValue: T {
            get {

                if let data = UserDefaults.standard.object(forKey: key) as? Data,
                    let user = try? JSONDecoder().decode(T.self, from: data) {
                    return user

                }

                return  defaultValue
            }
            set {
                if let encoded = try? JSONEncoder().encode(newValue) {
                    UserDefaults.standard.set(encoded, forKey: key)
                }
            }
        }
    }




enum GlobalSettings {

    @UserDefault("user", defaultValue: User(name:"",pass:"")) static var user: User
}

Example User model confirm Codable

struct User:Codable {
    let name:String
    let pass:String
}

How to use it

//Set value 
 GlobalSettings.user = User(name: "Ahmed", pass: "Ahmed")

//GetValue
print(GlobalSettings.user)

Try as given below:

while (MyReader.Read())
{
    TextBox1.Text = Convert.ToDateTime(MyReader["DateField"]).ToString("dd/MM/yyyy");
}

in ToString() method you can change data format as per your requirement.

You can set your tint color and font as setTitleTextattribute:

UIFont *font= (kUIScreenHeight>KipadHeight)?[UIFont boldSystemFontOfSize:32.0f]:[UIFont boldSystemFontOfSize:16.0f];
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:font, NSFontAttributeName,
                            tintColorLight, NSForegroundColorAttributeName, nil];
[[UINavigationBar appearance] setTitleTextAttributes:attributes];

asynchronous call ping command to block current code to execution in specified milliseconds.

• ping command is Cross-platform
• start /b means: start program but not show window.

code as below:

const { execSync } = require('child_process')
// delay(blocking) specified milliseconds
function sleep(ms) {
    // special Reserved IPv4 Address(RFC 5736): 192.0.0.0
    // refer: https://en.wikipedia.org/wiki/Reserved_IP_addresses
    execSync(`start /b ping 192.0.0.0 -n 1 -w ${ms} > nul`)
}

// usage
console.log("delay 2500ms start\t:" + (new Date().getTime() / 1000).toFixed(3))
sleep(2500)
console.log("delay 2500ms end\t:" + (new Date().getTime() / 1000).toFixed(3))

notice important: Above is not a precision solution, it just approach the blocking time

I don't know how exactly the bottom sheet of the new Maps app, responds to user interactions. But you can create a custom view that looks like the one in the screenshots and add it to the main view.

I assume you know how to:

1- create view controllers either by storyboards or using xib files.

2- use googleMaps or Apple's MapKit.

Example

1- Create 2 view controllers e.g, MapViewController and BottomSheetViewController. The first controller will host the map and the second is the bottom sheet itself.

Configure MapViewController

Create a method to add the bottom sheet view.

func addBottomSheetView() {
    // 1- Init bottomSheetVC
    let bottomSheetVC = BottomSheetViewController()

    // 2- Add bottomSheetVC as a child view 
    self.addChildViewController(bottomSheetVC)
    self.view.addSubview(bottomSheetVC.view)
    bottomSheetVC.didMoveToParentViewController(self)

    // 3- Adjust bottomSheet frame and initial position.
    let height = view.frame.height
    let width  = view.frame.width
    bottomSheetVC.view.frame = CGRectMake(0, self.view.frame.maxY, width, height)
}

And call it in viewDidAppear method:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    addBottomSheetView()
}

Configure BottomSheetViewController

1) Prepare background

Create a method to add blur and vibrancy effects

func prepareBackgroundView(){
    let blurEffect = UIBlurEffect.init(style: .Dark)
    let visualEffect = UIVisualEffectView.init(effect: blurEffect)
    let bluredView = UIVisualEffectView.init(effect: blurEffect)
    bluredView.contentView.addSubview(visualEffect)

    visualEffect.frame = UIScreen.mainScreen().bounds
    bluredView.frame = UIScreen.mainScreen().bounds

    view.insertSubview(bluredView, atIndex: 0)
}

call this method in your viewWillAppear

override func viewWillAppear(animated: Bool) {
   super.viewWillAppear(animated)
   prepareBackgroundView()
}

Make sure that your controller's view background color is clearColor.

2) Animate bottomSheet appearance

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    UIView.animateWithDuration(0.3) { [weak self] in
        let frame = self?.view.frame
        let yComponent = UIScreen.mainScreen().bounds.height - 200
        self?.view.frame = CGRectMake(0, yComponent, frame!.width, frame!.height)
    }
}

3) Modify your xib as you want.

4) Add Pan Gesture Recognizer to your view.

In your viewDidLoad method add UIPanGestureRecognizer.

override func viewDidLoad() {
    super.viewDidLoad()

    let gesture = UIPanGestureRecognizer.init(target: self, action: #selector(BottomSheetViewController.panGesture))
    view.addGestureRecognizer(gesture)

}

And implement your gesture behaviour:

func panGesture(recognizer: UIPanGestureRecognizer) {
    let translation = recognizer.translationInView(self.view)
    let y = self.view.frame.minY
    self.view.frame = CGRectMake(0, y + translation.y, view.frame.width, view.frame.height)
     recognizer.setTranslation(CGPointZero, inView: self.view)
}

Scrollable Bottom Sheet:

If your custom view is a scroll view or any other view that inherits from, so you have two options:

First:

Design the view with a header view and add the panGesture to the header. (bad user experience).

Second:

1 - Add the panGesture to the bottom sheet view.

2 - Implement the UIGestureRecognizerDelegate and set the panGesture delegate to the controller.

3- Implement shouldRecognizeSimultaneouslyWith delegate function and disable the scrollView isScrollEnabled property in two case:

• The view is partially visible.
• The view is totally visible, the scrollView contentOffset property is 0 and the user is dragging the view downwards.

Otherwise enable scrolling.

  func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
      let gesture = (gestureRecognizer as! UIPanGestureRecognizer)
      let direction = gesture.velocity(in: view).y

      let y = view.frame.minY
      if (y == fullView && tableView.contentOffset.y == 0 && direction > 0) || (y == partialView) {
          tableView.isScrollEnabled = false
      } else {
        tableView.isScrollEnabled = true
      }

      return false
  }

NOTE

In case you set .allowUserInteraction as an animation option, like in the sample project, so you need to enable scrolling on the animation completion closure if the user is scrolling up.

Sample Project

I created a sample project with more options on this repo which may give you better insights about how to customise the flow.

In the demo, addBottomSheetView() function controls which view should be used as a bottom sheet.

Sample Project Screenshots

- Partial View

- FullView

- Scrollable View

SQL Server Reporting Services (SSRS)
SSRS can remain active even if you uninstall SQL Server.
To stop the service:

Open SQL Server Configuration Manager. Select “SQL Server Services” in the left-hand pane. Double-click “SQL Server Reporting Services”. Hit Stop. Switch to the Service tab and set the Start Mode to “Manual”.

Skype
Irritatingly, Skype can switch to port 80. To disable it, select
Tools > Options > Advanced > Connection then uncheck
“Use port 80 and 443 as alternatives for incoming connections”.

IIS (Microsoft Internet Information Server)

For Windows 7 (or vista) its the most likely culprit. You can stop the service from the command line.

Open command line cmd.exe and type:

net stop was /y

For older versions of Windows type:

net stop iisadmin /y

Other

If this does not solve the problem further detective work is necessary if IIS, SSRS and Skype are not to blame. Enter the following on the command line:

netstat -ao

The active TCP addresses and ports will be listed. Locate the line with local address “0.0.0.0:80" and note the PID value. Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.

There's a solution at CMD: Set buffer height independently of window height effectively employing a powershell command executed from the batch script. This solution let me resize the scrollback buffer in the existing batch script window independently of the window size, exactly what the OP was asking for.

Caveat: It seems to make the script forget variables (or at least it did with my script), so I recommend calling the command only at the beginning and / or end of your script, or otherwise where you don't depend on a session local variable.

The usage info:

Usage: brew switch <formula> <version>

Example:

brew switch mysql 5.5.29

You can find the versions installed on your system with info.

brew info mysql

And to see the available versions to install, you can provide a dud version number, as brew will helpfully respond with the available version numbers:

brew switch mysql 0

Update (15.10.2014):

The brew versions command has been removed from brew, but, if you do wish to use this command first run brew tap homebrew/boneyard.

The recommended way to install an old version is to install from the homebrew/versions repo as follows:

$ brew tap homebrew/versions
$ brew install mysql55

For detailed info on all the ways to install an older version of a formula read this answer.

For people who are looking for a GUI solution, Git Cola has a very nice "Branch Diff Viewer (Diff -> Branches..).

To add onto what Arve Systad mentioned for testing. If for whatever reason you're like me and want to maintain the inheritance structure provided in theutz solution, you can set up the MapperConfiguration like so:

var mappingProfile = new MappingProfile();
var config = new MapperConfiguration(cfg =>
{
    cfg.AddProfile(mappingProfile);
});
var mapper = new Mapper(config);

I did this in NUnit.

It doesn't work with PostgreSQL 9.4 on my Linux machine if i change a table through table editor in pgAdmin and works if i change table through ordinary query. Manual changes in pg_trigger table also don't work without server restart but dynamic query like on postgresql.nabble.com ENABLE / DISABLE ALL TRIGGERS IN DATABASE works. It could be useful when you need some tuning.

For example if you have tables in a particular namespace it could be:

create or replace function disable_triggers(a boolean, nsp character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_namespace n
        join pg_class c on c.relnamespace = n.oid and c.relhastriggers = true
        where n.nspname = nsp
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

If you want to disable all triggers with certain trigger function it could be:

create or replace function disable_trigger_func(a boolean, f character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_proc p 
        join pg_trigger t on t.tgfoid = p.oid
        join pg_class c on c.oid = t.tgrelid
        where p.proname = f
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

PostgreSQL documentation for system catalogs

There are another control options of trigger firing process:

ALTER TABLE ... ENABLE REPLICA TRIGGER ... - trigger will fire in replica mode only.

ALTER TABLE ... ENABLE ALWAYS TRIGGER ... - trigger will fire always (obviously)

You can do it in pure CSS using the :after pseudo-element and getting creative with the margins.

Here's an example, using Font Awesome for the search icon:

.search-box-container input {_x000D_
  padding: 5px 20px 5px 5px;_x000D_
}_x000D_
_x000D_
.search-box-container:after {_x000D_
    content: "\f002";_x000D_
    font-family: FontAwesome;_x000D_
    margin-left: -25px;_x000D_
    margin-right: 25px;_x000D_
}

i Solve My Problem Through this Method

From Java 8 API

It could be easier to take actual implementation from API doc https://docs.oracle.com/javase/8/docs/api/java/util/Random.html#longs-long-long-long- they are using it to generate longs stream. And your origin can be "0" like in the question.

long nextLong(long origin, long bound) {
  long r = nextLong();
  long n = bound - origin, m = n - 1;
  if ((n & m) == 0L)  // power of two
    r = (r & m) + origin;
  else if (n > 0L) {  // reject over-represented candidates
    for (long u = r >>> 1;            // ensure nonnegative
         u + m - (r = u % n) < 0L;    // rejection check
         u = nextLong() >>> 1) // retry
        ;
    r += origin;
  }
  else {              // range not representable as long
    while (r < origin || r >= bound)
      r = nextLong();
  }
  return r;
}

You just need to toggle the value of "isReplyFormOpen" on ng-click event

<a ng-click="isReplyFormOpen = !isReplyFormOpen">Reply</a>
 <div ng-show="isReplyFormOpen" id="replyForm">
   </div>

Running npm start from react-native directory worked out for me.

This is simple way (thanks Gson)

String retVal = parser.parse(param).getAsString();

In order to do this for multiple items do something like:

foreach (var item in Model)
{
    @Html.RadioButtonFor(m => m.item, "Yes") @:Yes
    @Html.RadioButtonFor(m => m.item, "No") @:No
}

I know this thread is old, but for others who encounter the same problem, that implement @Brad8118 solution (which i prefer, because if you choose to make the input readonly then the user will not be able to delete the date value inserted from datepicker if he chooses) and also need to prevent the user from pasting a value (as @ErikPhilips suggested to be needed), I let this addition here, which worked for me: $("#my_txtbox").bind('paste',function(e) { e.preventDefault(); //disable paste }); from here https://www.dotnettricks.com/learn/jquery/disable-cut-copy-and-paste-in-textbox-using-jquery-javascript and the whole specific script used by me (using fengyuanchen/datepicker plugin instead):

$('[data-toggle="datepicker"]').datepicker({
    autoHide: true,
    pick: function (e) {
        e.preventDefault();
        $(this).val($(this).datepicker('getDate', true));
    }
}).keypress(function(event) {
    event.preventDefault(); // prevent keyboard writing but allowing value deletion
}).bind('paste',function(e) {
    e.preventDefault()
}); //disable paste;

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

Do not forget that you also can pass these use variables by reference.

The use cases are when you need to change the use'd variable from inside of your callback (e.g. produce the new array of different objects from some source array of objects).

$sourcearray = [ (object) ['a' => 1], (object) ['a' => 2]];
$newarray = [];
array_walk($sourcearray, function ($item) use (&$newarray) {
    $newarray[] = (object) ['times2' => $item->a * 2];
});
var_dump($newarray);

Now $newarray will comprise (pseudocode here for brevity) [{times2:2},{times2:4}].

On the contrary, using $newarray with no & modifier would make outer $newarray variable be read-only accessible from within the closure scope. But $newarray within closure scope would be a completelly different newly created variable living only within the closure scope.

Despite both variables' names are the same these would be two different variables. The outer $newarray variable would comprise [] in this case after the code has finishes.

They are ASCII dec codes. A full table can be found here.

This is another solution to convert HTML to Text or RTF in C#:

    SautinSoft.HtmlToRtf h = new SautinSoft.HtmlToRtf();
    h.OutputFormat = HtmlToRtf.eOutputFormat.TextUnicode;
    string text = h.ConvertString(htmlString);

This library is not free, this is commercial product and it is my own product.

Maybe a little late to reply. I happen to run into the same problem today. I find that on Windows you can change the console encoder to utf-8 or other encoder that can represent your data. Then you can print it to sys.stdout.

First, run following code in the console:

chcp 65001
set PYTHONIOENCODING=utf-8

Then, start python do anything you want.

Read directly into allocated space with fgets().

Special care is need to distinguish a successful read, end-of-file, input error and out-of memory. Proper memory management needed on EOF.

This method retains a line's '\n'.

#include <stdio.h>
#include <stdlib.h>

#define FGETS_ALLOC_N 128

char* fgets_alloc(FILE *istream) {
  char* buf = NULL;
  size_t size = 0;
  size_t used = 0;
  do {
    size += FGETS_ALLOC_N;
    char *buf_new = realloc(buf, size);
    if (buf_new == NULL) {
      // Out-of-memory
      free(buf);
      return NULL;
    }
    buf = buf_new;
    if (fgets(&buf[used], (int) (size - used), istream) == NULL) {
      // feof or ferror
      if (used == 0 || ferror(istream)) {
        free(buf);
        buf = NULL;
      }
      return buf;
    }
    size_t length = strlen(&buf[used]);
    if (length + 1 != size - used) break;
    used += length;
  } while (buf[used - 1] != '\n');
  return buf;
}

Sample usage

int main(void) {
  FILE *istream = stdin;
  char *s;
  while ((s = fgets_alloc(istream)) != NULL) {
    printf("'%s'", s);
    free(s);
    fflush(stdout);
  }
  if (ferror(istream)) {
    puts("Input error");
  } else if (feof(istream)) {
    puts("End of file");
  } else {
    puts("Out of memory");
  }
  return 0;
}

If the size of the circles corresponds to the square of the parameter in s=parameter, then assign a square root to each element you append to your size array, like this: s=[1, 1.414, 1.73, 2.0, 2.24] such that when it takes these values and returns them, their relative size increase will be the square root of the squared progression, which returns a linear progression.

If I were to square each one as it gets output to the plot: output=[1, 2, 3, 4, 5]. Try list interpretation: s=[numpy.sqrt(i) for i in s]

:.,$d

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

There is a operator < between lists e.g.:

[12, 'tall', 'blue', 1] < [4, 'tall', 'blue', 13]

will give

False

Here is what I uses to search for multiple words in multiple columns - SQL server

Hope my answer help someone :) Thanks

declare @searchTrm varchar(MAX)='one two three ddd 20   30 comment';

        and(    
        BolNumber like '%'+ value+'%'
        or UserComment like '%'+ value+'%'

Option 1 - run useEffect when value changes

const Component = (props) => {

  useEffect(() => {
    console.log("val1 has changed");
  }, [val1]);

  return <div>...</div>;
};

Demo

Option 2 - useHasChanged hook

Comparing a current value to a previous value is a common pattern, and justifies a custom hook of it's own that hides implementation details.

const Component = (props) => {
  const hasVal1Changed = useHasChanged(val1)

  useEffect(() => {
    if (hasVal1Changed ) {
      console.log("val1 has changed");
    }
  });

  return <div>...</div>;
};

const useHasChanged= (val: any) => {
    const prevVal = usePrevious(val)
    return prevVal !== val
}

const usePrevious = (value) => {
    const ref = useRef();
    useEffect(() => {
      ref.current = value;
    });
    return ref.current;
}

Extending @Tinker's answer,

In my case, I needed to make a command | command | command inside the -exec to print both the filename and the found text in files containing a certain text.

I was able to do it with:

find . -name config -type f \( -exec  grep "bitbucket" {} \; -a -exec echo {} \;  \) 

the result is:

    url = [email protected]:a/a.git
./a/.git/config
    url = [email protected]:b/b.git
./b/.git/config
    url = [email protected]:c/c.git
./c/.git/config

1st put "yourmp3file".mp3 file in the raw folder(ie inside Res folder)

2nd in your code put..

Notification noti = new Notification.Builder(this)
.setSound(Uri.parse("android.resource://" + v.getContext().getPackageName() + "/" + R.raw.yourmp3file))//*see note

This is what i put inside my onClick(View v) as only "context().getPackageName()" wont work from there as it wont get any context

Problem

Floating point can't store all decimal values exactly. So when using floating point formats there will always be rounding errors on the input values. The errors on the inputs of course results on errors on the output. In case of a discrete function or operator there can be big differences on the output around the point where the function or operator is discrete.

Input and output for floating point values

So, when using floating point variables, you should always be aware of this. And whatever output you want from a calculation with floating points should always be formatted/conditioned before displaying with this in mind.
When only continuous functions and operators are used, rounding to the desired precision often will do (don't truncate). Standard formatting features used to convert floats to string will usually do this for you.
Because the rounding adds an error which can cause the total error to be more then half of the desired precision, the output should be corrected based on expected precision of inputs and desired precision of output. You should

• Round inputs to the expected precision or make sure no values can be entered with higher precision.
• Add a small value to the outputs before rounding/formatting them which is smaller than or equal to 1/4 of the desired precision and bigger than the maximum expected error caused by rounding errors on input and during calculation. If that is not possible the combination of the precision of the used data type isn't enough to deliver the desired output precision for your calculation.

These 2 things are usually not done and in most cases the differences caused by not doing them are too small to be important for most users, but I already had a project where output wasn't accepted by the users without those corrections.

Discrete functions or operators (like modula)

When discrete operators or functions are involved, extra corrections might be required to make sure the output is as expected. Rounding and adding small corrections before rounding can't solve the problem.
A special check/correction on intermediate calculation results, immediately after applying the discrete function or operator might be required. For a specific case (modula operator), see my answer on question: Why does modulus operator return fractional number in javascript?

Better avoid having the problem

It is often more efficient to avoid these problems by using data types (integer or fixed point formats) for calculations like this which can store the expected input without rounding errors. An example of that is that you should never use floating point values for financial calculations.

Try CountDownLatch class out of the java.util.concurrent package, which provides higher level synchronization mechanisms, that are far less error prone than any of the low level stuff.

Command works only if "use" -command has been first used to define the database where working in. Table column renaming syntax using DATABASE.TABLE throws error and does not work. Version: HIVE 0.12.

EXAMPLE:

hive> ALTER TABLE tablename CHANGE old_column_name new_column_name;

OK

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

Reinstall numpy-1.11.0_XXX.whl (for your Python) from www.lfd.uci.edu/~gohlke/pythonlibs. This file has the same name and version if compare with the variant downloaded by me earlier 29.03.2016, but its size and content differ from old variant. After re-installation error disappeared.

Second option - return back to scipy 0.17.0 from 0.17.1

P.S. I use Windows 64-bit version of Python 3.5.1, so can't guarantee that numpy for Python 2.7 is already corrected.

It seems that the accepted answers are no longer the case when using React hooks. You can see in this code sandbox that the class component is rerendered when the state is set to the same value, while in the function component, setting the state to the same value doesn't cause a rerender.

If I have an enum as follows:

public enum TestEnum
{
    Value1 = 1,
    Value2 = 2,
    Value3 = 3
}

then I can make use of above methods as

TestEnum reqValue = GetEnumValue<TestEnum>("Value1");  // Output: Value1
TestEnum reqValue2 = GetEnumValue<TestEnum>(2);        // OutPut: Value2

Hope this will help.

I use PyCharm which has great capabilities to compare between folders and files.

Just open the parent folder for both repos and wait until it indexes. Then you can use right click on a folder or file and Compare to... and pick the corresponding folder / file on the other side.

It shows not only what files are different but also their content. Much easier than command line.

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

Are you sure you don't want to actually merge the branches? If the working branch has some recent commits you don't want, you can just create a new branch with a HEAD at the point you want.

Now, if you really do want to cherry-pick a range of commits, for whatever reason, an elegant way to do this is to just pull of a patchset and apply it to your new integration branch:

git format-patch A..B
git checkout integration
git am *.patch

This is essentially what git-rebase is doing anyway, but without the need to play games. You can add --3way to git-am if you need to merge. Make sure there are no other *.patch files already in the directory where you do this, if you follow the instructions verbatim...

I use the below query

SELECT   SPID       = er.session_id
    ,STATUS         = ses.STATUS
    ,[Login]        = ses.login_name
    ,Host           = ses.host_name
    ,BlkBy          = er.blocking_session_id

You can use the path module to join the path of the directory in which helper1.js lives to the relative path of foobar.json. This will give you the absolute path to foobar.json.

var fs = require('fs');
var path = require('path');

var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');

This should work on Linux, OSX, and Windows assuming a UTF8 encoding.

You can do it like this:

function fillArray(value, len) {
  if (len == 0) return [];
  var a = [value];
  while (a.length * 2 <= len) a = a.concat(a);
  if (a.length < len) a = a.concat(a.slice(0, len - a.length));
  return a;
}

It doubles the array in each iteration, so it can create a really large array with few iterations.

Note: You can also improve your function a lot by using push instead of concat, as concat will create a new array each iteration. Like this (shown just as an example of how you can work with arrays):

function fillArray(value, len) {
  var arr = [];
  for (var i = 0; i < len; i++) {
    arr.push(value);
  }
  return arr;
}

 public void removeDuplicates() {
    ArrayList<Object> al = new ArrayList<Object>();
    al.add("java");
    al.add('a');
    al.add('b');
    al.add('a');
    al.add("java");
    al.add(10.3);
    al.add('c');
    al.add(14);
    al.add("java");
    al.add(12);

    System.out.println("Before Remove Duplicate elements:" + al);
    for (int i = 0; i < al.size(); i++) {
        for (int j = i + 1; j < al.size(); j++) {
            if (al.get(i).equals(al.get(j))) {
                al.remove(j);
                j--;
            }
        }
    }
    System.out.println("After Removing duplicate elements:" + al);
}

Before Remove Duplicate elements:

[java, a, b, a, java, 10.3, c, 14, java, 12]

After Removing duplicate elements:

[java, a, b, 10.3, c, 14, 12]

I agree with the current answers, I just wanna add little more information.

A new feature has been added to Laravel 5.3 and above version that will allow you to back out a single migration:

php artisan migrate:rollback --step=1

after, Manually delete the migration file under database/migrations/my_migration_file_name.php

This is a great feature for when you run a migration

In this way, you can safely remove the migration in laravel only in 2 step

The key for me to be able to connect was to use the "ec2-user" user rather than root. I.e.:

ssh -i [full path to keypair file] ec2-user@[EC2 instance hostname or IP address]

Use the Maven debug option, ie mvn -X :

In this output, you can see that the settings.xml is loaded from /home/myhome/.m2/settings.xml.

You have copy this sample code from Here,right?
now, as you can see there property file they have define, have you done same thing? if not then add below code in your project with property file for log4j

So the content of log4j.properties file would be as follows:

# Define the root logger with appender file
log = /usr/home/log4j
log4j.rootLogger = DEBUG, FILE

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=${log}/log.out

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n

make changes as per your requirement like log path

Given

d = [[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]

and your specific question: How can I remove the brackets?

Using list comprehension :

new_d = [i[0] for i in d]

will give you this

[180.0, 173.8, 164.2, 156.5, 147.2, 138.2]

then you can access individual items with the appropriate index, e.g., new_d[0] will give you 180.0 etc which you can then use for math.

If you are going to have a collection of data, you will have some sort of bracket or parenthesis.

Note, this solution is aimed specifically at your question/problem, it doesn't provide a generalized solution. I.e., it will work for your case.

Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.

My setup was as follows:

• Sheet1: full data of 2014
• Sheet2: updated rows for 2015 in A1:D50, sorted by first column
• Sheet3: merged rows
• My data does not have a header row

I put the following formula in cell A1 of Sheet3:

=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)

Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.

Notes:

• In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.

• A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.

After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:

=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)

and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.

Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.

Cells A2, A3, etc. will get these formulas:

=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)

Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.

With a Swift slant and want a bare-bones example, here is my go-to method for passing data if you are using a segue to get around.

It is similar to the above but without the buttons, labels and such. Just simply passing data from one view to the next.

Setup The Storyboard

There are three parts.

1. The Sender
2. The Segue
3. The Receiver

This is a very simple view layout with a segue between them.

Here is the setup for the sender

Here is the setup for the receiver.

Lastly, the setup for the segue.

The View Controllers

We are keeping this simple so no buttons and not actions. We are simply moving data from the sender to the receiver when the application loads and then outputting the transmitted value to the console.

This page takes the initially loaded value and passes it along.

import UIKit


class ViewControllerSender: UIViewController {

    // THE STUFF - put some information into a variable
    let favoriteMovie = "Ghost Busters"

    override func viewDidAppear(animated: Bool) {
        // PASS IDENTIFIER - go to the receiving view controller.
        self.performSegueWithIdentifier("goToReciever", sender: self)
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

        // GET REFERENCE - ...to the receiver view.
        var viewControllerReceiver = segue.destinationViewController as? ViewControllerReceiver

        // PASS STUFF - pass the variable along to the target.
        viewControllerReceiver!.yourFavMovie = self.favoriteMovie

    }
}

This page just sends the value of the variable to the console when it loads. By this point, our favorite movie should be in that variable.

import UIKit

class ViewControllerReceiver: UIViewController {

    // Basic empty variable waiting for you to pass in your fantastic favorite movie.
    var yourFavMovie = ""

    override func viewDidLoad() {
        super.viewDidLoad()

        // And now we can view it in the console.
        println("The Movie is \(self.yourFavMovie)")

    }
}

That is how you can tackle it if you want to use a segue and you don't have your pages under a navigation controller.

Once it is run, it should switch to the receiver view automatically and pass the value from the sender to the receiver, displaying the value in the console.

You can install gems into a specific folder (example vendor/) in your Rails app using :

bundle install --path vendor

I have a ZTE Crescent phone (Orange San Francisco II).

When I connect the phone to the USB a disk shows up in OS X named 'ZTE_USB_Driver'.

Running adb devices displays no connected devices. But after I eject the 'ZTE_USB_Driver' disk from OS X, and run adb devices again the phone shows up as connected.

Can you output that data in the cells as you are creating the table?

so your table would look like this:

<table>
  <thead>...</thead>
  <tbody>
    <tr><td data-row='1' data-column='1'>value</td>
      <td data-row='1' data-column='2'>value</td>
      <td data-row='1' data-column='3'>value</td></tr>

  <tbody>
</table>

then it would be a simple matter

$("td").click(function(event) {
   var row = $(this).attr("data-row");
   var col = $(this).attr("data-col");
}

Your second example does not work because there is no operator + for two string literals. Note that a string literal is not of type string, but instead is of type const char *. Your second example will work if you revise it like this:

const string message = string("Hello") + ",world" + exclam;

All WebServices is API but all API is not WebServices, API which is exposed on Web is called web services.

To set image cource in imageview you can use any of the following ways. First confirm your image is present in which format.

If you have image in the form of bitmap then use

imageview.setImageBitmap(bm);

If you have image in the form of drawable then use

imageview.setImageDrawable(drawable);

If you have image in your resource example if image is present in drawable folder then use

imageview.setImageResource(R.drawable.image);

If you have path of image then use

imageview.setImageURI(Uri.parse("pathofimage"));

Vue.js considers this an anti-pattern. For example, declaring and setting some props like

this.propsVal = 'new Props Value'

So to solve this issue you have to take in a value from the props to the data or the computed property of a Vue instance, like this:

props: ['propsVal'],
data: function() {
   return {
       propVal: this.propsVal
   };
},
methods: {
...
}

This will definitely work.

Or if you don't like branching, just negate the two parameters and add 180° to the answer.

(Adding 180° to the return value puts it nicely in the 0-360 range, but flips the angle. Negating both input parameters flips it back.)

    public static function normalizeUrl(string $url) {
        $parts = parse_url($url);
        return $parts['scheme'] .
            '://' .
            $parts['host'] .
            implode('/', array_map('rawurlencode', explode('/', $parts['path'])));

    }

As described by @mplungjan, I though it was right. Then right away I click the up rate button. But by following it, I finally got an error.

<script>
var data = {"result":[
  {"FirstName":"Test1","LastName":"User","Email":"[email protected]","City":"ahmedabad","State":"sk","Country":"canada","Status":"False","iUserID":"23"},
  {"FirstName":"user","LastName":"user","Email":"[email protected]","City":"ahmedabad","State":"Gujarat","Country":"India","Status":"True","iUserID":"41"},
  {"FirstName":"Ropbert","LastName":"Jones","Email":"[email protected]","City":"NewYork","State":"gfg","Country":"fgdfgdfg","Status":"True","iUserID":"48"},
  {"FirstName":"hitesh","LastName":"prajapti","Email":"[email protected]","City":"","State":"","Country":"","Status":"True","iUserID":"78"}
  ]
}
alert(data.result)
delete data.result[3]
alert(data.result)
</script>

Delete is just remove the data, but the 'place' is still there as undefined.

I did this and it works like a charm :

data.result.splice(2,1);  

meaning : delete 1 item at position 3 ( because array is counted form 0, then item at no 3 is counted as no 2 )

How about using the ExecutorService.shutDownNow() method as described in http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html? It seems to be the simplest solution.

The second top answer mentions ifeq, however, it fails to mention that these must be on the same level as the name of the target, e.g., to download a file only if it doesn't currently exist, the following code could be used:

download:
ifeq (,$(wildcard ./glob.c))
    curl … -o glob.c
endif

# THIS DOES NOT WORK!
download:
    ifeq (,$(wildcard ./glob.c))
        curl … -o glob.c
    endif

This is working for me on iOS 6.1 and with Bootstrap JS links (i.e dropdown menus etc)

$(document).ready(function(){
    if (("standalone" in window.navigator) && window.navigator.standalone) {
      // For iOS Apps
      $('a').on('click', function(e){
        e.preventDefault();
        var new_location = $(this).attr('href');
        if (new_location != undefined && new_location.substr(0, 1) != '#' && $(this).attr('data-method') == undefined){
          window.location = new_location;
        }
      });
    }
  });

To use video extensions that are MKV. You should use video, not source

For example :

  <!-- mkv -->
  <video width="320" height="240" controls src="assets/animation.mkv"></video>
<!-- mp4 -->
  <video width="320" height="240" controls>
    <source src="assets/animation.mp4" type="video/mp4" />
  </video>

Still using indirect. Say your A1 cell is your variable that will contain the name of the referenced sheet (Jan). If you go by:

=INDIRECT(CONCATENATE("'",A1," Item'", "!J3"))

Then you will have the 'Jan Item'!J3 value.

If you need a fully qualified domain name and have no HTTP request, on Linux, you could use:

var child_process = require("child_process");

child_process.exec("hostname -f", function(err, stdout, stderr) {
  var hostname = stdout.trim();
});

SELECT *  
  FROM (SELECT ROW_NUMBER () OVER (ORDER BY user_id) user_row_no, a.* FROM temp_emp a)  
 WHERE user_row_no > 1 and user_row_no <11  

This worked for me.If i may,i have few useful dbscripts that you can have look at

Useful Dbscripts

This is the one I use

(http|ftp|https)://([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:/~+#-]*[\w@?^=%&/~+#-])?

Works for me, should work for you too.

By keys() and values() methods of dictionary and zip.

zip will return a list of tuples which acts like an ordered dictionary.

Demo:

>>> d = { 'a': 1, 'b': 2, 'c': 3 }
>>> zip(d.keys(), d.values())
[('a', 1), ('c', 3), ('b', 2)]
>>> zip(d.values(), d.keys())
[(1, 'a'), (3, 'c'), (2, 'b')]

Well, the above answer is correct, auto_now_add and auto_now would do it, but it would be better to make an abstract class and use it in any model where you require created_at and updated_at fields.

class TimeStampMixin(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

Now anywhere you want to use it you can do a simple inherit and you can use timestamp in any model you make like.

class Posts(TimeStampMixin):
    name = models.CharField(max_length=50)
    ...
    ...

In this way, you can leverage object-oriented reusability, in Django DRY(don't repeat yourself)

Your code has lots of errors.

• You are mixing up dm$Day and dm$day. Probably not the same thing
• Your column headings are Date and Visits. So you would access them (I'm guessing) as dm$Date and dm$Visits
• In the date field you have %Y-%m-%d this should be %m/%d/%Y

The following code should plot what you want:

dm$newday = as.Date(dm$Date, "%m/%d/%Y")
plot(dm$newday, dm$Visits)

If anyone is strugling with the same problem I solved it by adding @EntityScan in my main class. Just add your model package to the basePackages property.

getValue = function (object, key) {
    return key.split(".").reduce(function (obj, val) {
        return (typeof obj == "undefined" || obj === null || obj === "") ? obj : (_.isString(obj[val]) ? obj[val].trim() : obj[val]);}, object);
};

var obj = {
   "a": "test1",
   "b": "test2"
};

Function called:

 getValue(obj, "a");

You can use a byte literal in Java... sort of.

    byte f = 0;
    f = 0xa;

0xa (int literal) gets automatically cast to byte. It's not a real byte literal (see JLS & comments below), but if it quacks like a duck, I call it a duck.

What you can't do is this:

void foo(byte a) {
   ...
}

 foo( 0xa ); // will not compile

You have to cast as follows:

 foo( (byte) 0xa ); 

But keep in mind that these will all compile, and they are using "byte literals":

void foo(byte a) {
   ...
}

    byte f = 0;

    foo( f = 0xa ); //compiles

    foo( f = 'a' ); //compiles

    foo( f = 1 );  //compiles

Of course this compiles too

    foo( (byte) 1 );  //compiles

If you design query using the Query editor in SQL Server 2012 for example you would get this:

  SELECT        e.EmployeeID, s.CompanyName, o.ShipName
FROM            Employees AS e INNER JOIN
                         Orders AS o ON e.EmployeeID = o.EmployeeID INNER JOIN
                         Shippers AS s ON o.ShipVia = s.ShipperID
WHERE        (s.CompanyName = 'Federal Shipping')

However removing the AS does not make any difference as in the following:

 SELECT        e.EmployeeID, s.CompanyName, o.ShipName
FROM            Employees e INNER JOIN
                         Orders o ON e.EmployeeID = o.EmployeeID INNER JOIN
                         Shippers s ON o.ShipVia = s.ShipperID
WHERE        (s.CompanyName = 'Federal Shipping')

In this case use of AS is superfluous but in many other places it is needed.

1- nginx user and php-fpm and your site owner user must be same :

run command sudo vi /etc/nginx/nginx.conf change like bellow

user nginx nginx;

run command sudo vi /etc/nginx/nginx.conf change like bellow

listen.owner = nginx
listen.group = nginx
listen.mode = 0660

then restart nginx and php-fpm service

and go in project path and run below command

sudo chmod nginx:nginx -R .

2- change file SELinux security context by run following commands in project path

chcon -R -t httpd_sys_content_t .
chcon -R -t httpd_sys_rw_content_t .

I figured out how to do this in Powershell that someone asked about:

$keyname=(((gci cert:\LocalMachine\my | ? {$_.thumbprint -like $thumbprint}).PrivateKey).CspKeyContainerInfo).UniqueKeyContainerName
$keypath = $env:ProgramData + “\Microsoft\Crypto\RSA\MachineKeys\”
$fullpath=$keypath+$keyname

$Acl = Get-Acl $fullpath
$Ar = New-Object System.Security.AccessControl.FileSystemAccessRule("IIS AppPool\$iisAppPoolName", "Read", "Allow")
$Acl.SetAccessRule($Ar)
Set-Acl $fullpath $Acl

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Try this:

$('element').attr('id', 'value');

So it becomes;

$(function() {
    $('span .breadcrumb').each(function(){
        $('#nav').attr('id', $(this).text());
        $('#container').attr('id', $(this).text());
        $('.stretch_footer').attr('id', $(this).text())
        $('#footer').attr('id', $(this).text());
    });
});

So you are changing/overwriting the id of three elements and adding an id to one element. You can modify as per you needs...

You should learn Redux and ReactRedux library.It will structure your states and props in one store and you can access them later in your components .

when using String array, you have to give size of array while initializing

eg

String[] str = new String[10];

you can use index 0-9 to store values

str[0] = "value1"
str[1] = "value2"
str[2] = "value3"
str[3] = "value4"
str[4] = "value5"
str[5] = "value6"
str[6] = "value7"
str[7] = "value8"
str[8] = "value9"
str[9] = "value10"

if you are using ArrayList instread of string array, you can use it without initializing size of array ArrayList str = new ArrayList();

you can add value by using add method of Arraylist

str.add("Value1");

get retrieve a value from arraylist, you can use get method

String s = str.get(0);

find total number of items by size method

int nCount = str.size();

Unit Testing HttpContext.Current.Session in MVC3 .NET

Hope it helps.

[TestInitialize]

}

This can be caused by the two sides of the connection disagreeing over whether the connection timed out or not during a keepalive. (Your code tries to reused the connection just as the server is closing it because it has been idle for too long.) You should basically just retry the operation over a new connection. (I'm surprised your library doesn't do this automatically.)

You can try this simple android dialog popup library to cut the cluttered dialog code. It is very simple to use on your activity. after that you can have this code in your activity to show dialog

Pop.on(this).with().title(R.string.title).layout(R.layout.custom_pop).show();

where R.layout.custom_pop is your custom layout the way you want to decorate your dialog.

I was facing the same issue for a eclipse project configured for Tomcat 7 runtime

Right click on project and go to project properties. Click on Deployment Assembly. I could notice that my spring library jars which I created during compile time with a user library was missing. Just add the jars and you should see no errors in console during tomcat start up

The memory for a & b is not allocated by you. The compiler is free to choose a read-only memory location to store the characters. So if you try to change it may result in seg fault. So I suggest you to create a character array yourself. Something like: char a[10]; strcpy(a, "Hello");

You can set timeout like this,

con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);

It works for me by delete all the apple developer Certification in the keychain. and generate it in the Xcode.

In this case, your test.js will not run, because you're loading it before jQuery. put it after jQuery:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<script type="text/javascript" src="test.js"></script>

Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.

In your case:

w_ (array, std::end(array))

• array will get us a pointer to the beginning of the array (didn't catch it's name),
• std::end(array) will get us an iterator to the end of the array.

Your operation did not fail.

Your backend service is saying that the response type it is returning is not provided in the Accept HTTP header in your Client request.

Ref: http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

1. Find out the response (content type) returned by Service.
2. Provide this (content type) in your request Accept header.

Beside other answers, I think the main reason to "why using Functional Interface other than directly with lambda expressions" can be related to nature of Java language which is Object Oriented.

The main attributes of Lambda expressions are: 1. They can be passed around 2. and they can executed in future in specific time (several times). Now to support this feature in languages, some other languages deal simply with this matter.

For instance in Java Script, a function (Anonymous function, or Function literals) can be addressed as a object. So, you can create them simply and also they can be assigned to a variable and so forth. For example:

var myFunction = function (...) {
    ...;
}
alert(myFunction(...));

or via ES6, you can use an arrow function.

const myFunction = ... => ...

Up to now, Java language designers have not accepted to handle mentioned features via these manner (functional programming techniques). They believe that Java language is Object Oriented and therefore they should solve this problem via Object Oriented techniques. They don't want to miss simplicity and consistency of Java language.

Therefore, they use interfaces, as when an object of an interface with just one method (I mean functional interface) is need you can replace it with a lambda expression. Such as:

ActionListener listener = event -> ...;

For an extensive coverage review the contents of RFC2965. Of course that doesn't necessarily mean that all browsers behave exactly the same way.

However in general the rule for default Path if none specified in the cookie is the path in the URL from which the Set-Cookie header arrived. Similarly the default for the Domain is the full host name in the URL from which the Set-Cookie arrived.

Matching rules for the domain require the cookie Domain to match the host to which the request is being made. The cookie can specify a wider domain match by include *. in the domain attribute of Set-Cookie (this one area that browsers may vary). Matching the path (assuming the domain matches) is a simple matter that the requested path must be inside the path specified on the cookie. Typically session cookies are set with path=/ or path=/applicationName/ so the cookie is available to all requests into the application.

• Will a cookie for .example.com be available for www.example.com? Yes
• Will a cookie for .example.com be available for example.com? Don't Know
• Will a cookie for example.com be available for www.example.com? Shouldn't but... *
• Will a cookie for example.com be available for anotherexample.com? No
• Will www.example.com be able to set cookie for example.com? Yes
• Will www.example.com be able to set cookie for www2.example.com? No (Except via .example.com)
• Will www.example.com be able to set cookie for .com? No (Can't set a cookie this high up the namespace nor can you set one for something like .co.uk).

* I'm unable to test this right now but I have an inkling that at least IE7/6 would treat the path example.com as if it were .example.com.

By using this way you can get the list of selected records.

GregorianCalendar gregorianCalendar = new GregorianCalendar();
Criteria cri = session.createCriteria(ProjectActivities.class);
cri.add(Restrictions.ge("EffectiveFrom", gregorianCalendar.getTime()));
List list = cri.list();

All the Records will be generated into list which are greater than or equal to '08-Oct-2012' or else pass the date of user acceptance date at 2nd parameter of Restrictions (gregorianCalendar.getTime()) of criteria to get the records.

The on-heap store refers to objects that will be present in the Java heap (and also subject to GC). On the other hand, the off-heap store refers to (serialized) objects that are managed by EHCache, but stored outside the heap (and also not subject to GC). As the off-heap store continues to be managed in memory, it is slightly slower than the on-heap store, but still faster than the disk store.

The internal details involved in management and usage of the off-heap store aren't very evident in the link posted in the question, so it would be wise to check out the details of Terracotta BigMemory, which is used to manage the off-disk store. BigMemory (the off-heap store) is to be used to avoid the overhead of GC on a heap that is several Megabytes or Gigabytes large. BigMemory uses the memory address space of the JVM process, via direct ByteBuffers that are not subject to GC unlike other native Java objects.

There is a way. $q.all(...

Thread

When you start an app, a process is created to execute the code. To efficiently use computing resource, threads can be started within the process so that multiple tasks can be executed at the time. So threads allow you to build efficient apps by utilizing cpu efficiently without idle time.

In Android, all components execute on a single called main thread. Android system queue tasks and execute them one by one on the main thread. When long running tasks are executed, app become unresponsive.

To prevent this, you can create worker threads and run background or long running tasks.

Handler

Since android uses single thread model, UI components are created non-thread safe meaning only the thread it created should access them that means UI component should be updated on main thread only. As UI component run on the main thread, tasks which run on worker threads can not modify UI components. This is where Handler comes into picture. Handler with the help of Looper can connect to new thread or existing thread and run code it contains on the connected thread.

Handler makes it possible for inter thread communication. Using Handler, background thread can send results to it and the handler which is connected to main thread can update the UI components on the main thread.

AsyncTask

AsyncTask provided by android uses both thread and handler to make running simple tasks in the background and updating results from background thread to main thread easy.

Please see android thread, handler, asynctask and thread pools for examples.

I faced this problem. My html was as below:

The short answer is "you can't". What you'll need to do is either use a subquery or you could convert your existing stored procedure in to a table function. Creating it as function would depend on how "reusable" you would need it to be.

I think the correct way to do is

brew upgrade mongodb

It will upgrade the mongodb formula. If you want to upgrade all outdated formula, simply

brew upgrade

I can recommend Elasticvue, which is modern, free and open source. It allows accessing your ES instance via browser add-ons quite easily (supports Firefox, Chrome, Edge). But there are also further ways.

Just make sure you set cors values in elasticsearch.yml appropiate.

If you know the number of elements per "row" and the width of the container you can use a selector to add a margin to the elements you need to cause a justified look.

I had rows of three divs I wanted justified so used the:

.tile:nth-child(3n+2) { margin: 0 10px }

this allows the center div in each row to have a margin that forces the 1st and 3rd div to the outside edges of the container

Also great for other things like borders background colors etc

All you have to do is create a subset of your dataframe where the isin method evaluates to False:

df = df[df['Column Name'].isin(['Value']) == False]

I understand that Node.js uses a single-thread and an event loop to process requests only processing one at a time (which is non-blocking).

I could be misunderstanding what you've said here, but "one at a time" sounds like you may not be fully understanding the event-based architecture.

In a "conventional" (non event-driven) application architecture, the process spends a lot of time sitting around waiting for something to happen. In an event-based architecture such as Node.js the process doesn't just wait, it can get on with other work.

For example: you get a connection from a client, you accept it, you read the request headers (in the case of http), then you start to act on the request. You might read the request body, you will generally end up sending some data back to the client (this is a deliberate simplification of the procedure, just to demonstrate the point).

At each of these stages, most of the time is spent waiting for some data to arrive from the other end - the actual time spent processing in the main JS thread is usually fairly minimal.

When the state of an I/O object (such as a network connection) changes such that it needs processing (e.g. data is received on a socket, a socket becomes writable, etc) the main Node.js JS thread is woken with a list of items needing to be processed.

It finds the relevant data structure and emits some event on that structure which causes callbacks to be run, which process the incoming data, or write more data to a socket, etc. Once all of the I/O objects in need of processing have been processed, the main Node.js JS thread will wait again until it's told that more data is available (or some other operation has completed or timed out).

The next time that it is woken, it could well be due to a different I/O object needing to be processed - for example a different network connection. Each time, the relevant callbacks are run and then it goes back to sleep waiting for something else to happen.

The important point is that the processing of different requests is interleaved, it doesn't process one request from start to end and then move onto the next.

To my mind, the main advantage of this is that a slow request (e.g. you're trying to send 1MB of response data to a mobile phone device over a 2G data connection, or you're doing a really slow database query) won't block faster ones.

In a conventional multi-threaded web server, you will typically have a thread for each request being handled, and it will process ONLY that request until it's finished. What happens if you have a lot of slow requests? You end up with a lot of your threads hanging around processing these requests, and other requests (which might be very simple requests that could be handled very quickly) get queued behind them.

There are plenty of others event-based systems apart from Node.js, and they tend to have similar advantages and disadvantages compared with the conventional model.

I wouldn't claim that event-based systems are faster in every situation or with every workload - they tend to work well for I/O-bound workloads, not so well for CPU-bound ones.

ISNA is the best function to use. I just did. I wanted all cells whose value was NOT in an array to conditionally format to a certain color.

=ISNA(VLOOKUP($A2,Sheet1!$A:$D,2,FALSE))

As NEOSWF points out above, the Paul Irish conditional comments stops the meta tag having any affect.

There are several fixes all here (http://nicolasgallagher.com/better-conditional-classnames-for-hack-free-css/)

These include:

Adding two HTML classes, using server headers and adding a conditional comment above the doctype.

On my latest project I decided to remove the Paul Irish conditional comments. I didn't like the idea of adding anything before the html without doing LOTS of testing first and it's nice to see what has been set just by looking at the HTML.

In the end I surrounded a div straight after the body and used conditional comments eg

  <!--[if IE 7]><div class="ie7"><!--<![endif]-->
  ... regular body stuff
  <!--[if IE 7]></div><!--<![endif]-->

I could have done this around the body but its more difficult with CMSs like Wordpress.

Obviously its another DIV inside the markup, but its only for older browsers.

I think it could be a per project based decision though.

I've also read something about the charset meta tag needing to come in the first 1024 bytes so this ensures that.

Sometimes the simplest, easiest to read ideas are the best and its definitely worth thinking about! Thanks to the 6th comment on the link above for pointing this out.

Why dont you take the string and split it

Example on the url

var url = "http://www.youtube.com/watch?p=DB852818BF378DAC&v=1q-k-uN73Gk"

you can do a split as

var params = url.split("?")[1].split("&");

You will get array of strings with params as name value pairs with "=" as the delimiter.

Raymond's answer is great for python2 (though, you don't need the abs() nor the parens around 10 ** 8). However, for python3, there are important caveats. First, you'll need to make sure you are passing an encoded string. These days, in most circumstances, it's probably also better to shy away from sha-1 and use something like sha-256, instead. So, the hashlib approach would be:

>>> import hashlib
>>> s = 'your string'
>>> int(hashlib.sha256(s.encode('utf-8')).hexdigest(), 16) % 10**8
80262417

If you want to use the hash() function instead, the important caveat is that, unlike in Python 2.x, in Python 3.x, the result of hash() will only be consistent within a process, not across python invocations. See here:

$ python -V
Python 2.7.5
$ python -c 'print(hash("foo"))'
-4177197833195190597
$ python -c 'print(hash("foo"))'
-4177197833195190597

$ python3 -V
Python 3.4.2
$ python3 -c 'print(hash("foo"))'
5790391865899772265
$ python3 -c 'print(hash("foo"))'
-8152690834165248934

This means the hash()-based solution suggested, which can be shortened to just:

hash(s) % 10**8

will only return the same value within a given script run:

#Python 2:
$ python2 -c 's="your string"; print(hash(s) % 10**8)'
52304543
$ python2 -c 's="your string"; print(hash(s) % 10**8)'
52304543

#Python 3:
$ python3 -c 's="your string"; print(hash(s) % 10**8)'
12954124
$ python3 -c 's="your string"; print(hash(s) % 10**8)'
32065451

So, depending on if this matters in your application (it did in mine), you'll probably want to stick to the hashlib-based approach.

Based on your description in the comments, you'd simply do an array concat:

var jsonArray1 = [{'name': "doug", 'id':5}, {'name': "dofug", 'id':23}];
var jsonArray2 = [{'name': "goud", 'id':1}, {'name': "doaaug", 'id':52}];
jsonArray1 = jsonArray1.concat(jsonArray2);
// jsonArray1 = [{'name': "doug", 'id':5}, {'name': "dofug", 'id':23}, 
//{'name': "goud", 'id':1}, {'name': "doaaug", 'id':52}];

It is now this For swift 3,

    let button = (sender as AnyObject)
    button.setTitle("Your text", for: .normal)

(The constant declaration of the variable is not necessary just make sure you use the sender from the button like this) :

    (sender as AnyObject).setTitle("Your text", for: .normal)

Remember this is used inside the IBAction of your button.

I work on normalize.css.

The main differences are:

1. Normalize.css preserves useful defaults rather than "unstyling" everything. For example, elements like sup or sub "just work" after including normalize.css (and are actually made more robust) whereas they are visually indistinguishable from normal text after including reset.css. So, normalize.css does not impose a visual starting point (homogeny) upon you. This may not be to everyone's taste. The best thing to do is experiment with both and see which gels with your preferences.

2. Normalize.css corrects some common bugs that are out of scope for reset.css. It has a wider scope than reset.css, and also provides bug fixes for common problems like: display settings for HTML5 elements, the lack of font inheritance by form elements, correcting font-size rendering for pre, SVG overflow in IE9, and the button styling bug in iOS.

3. Normalize.css doesn't clutter your dev tools. A common irritation when using reset.css is the large inheritance chain that is displayed in browser CSS debugging tools. This is not such an issue with normalize.css because of the targeted stylings.

4. Normalize.css is more modular. The project is broken down into relatively independent sections, making it easy for you to potentially remove sections (like the form normalizations) if you know they will never be needed by your website.

5. Normalize.css has better documentation. The normalize.css code is documented inline as well as more comprehensively in the GitHub Wiki. This means you can find out what each line of code is doing, why it was included, what the differences are between browsers, and more easily run your own tests. The project aims to help educate people on how browsers render elements by default, and make it easier for them to be involved in submitting improvements.

I've written in greater detail about this in an article about normalize.css

Sometimes I don't want to add items to a list when I instantiate it.

Instantiate a blank list

Dim blankList As List(Of String) = New List(Of String)

Add to the list

blankList.Add("Dis be part of me list") 'blankList is no longer blank, but you get the drift

Loop through the list

For Each item in blankList
  ' write code here, for example:
  Console.WriteLine(item)
Next

Just a suggestion,in your code instead of using let newData = prevState.data you could use spread which is introduced in ES6 that is you can uselet newData = ...prevState.data for copying array

Three dots ... represents Spread Operators or Rest Parameters,

It allows an array expression or string or anything which can be iterating to be expanded in places where zero or more arguments for function calls or elements for array are expected.

Additionally you can delete item from array with following

onRemovePerson: function(index) {
  this.setState((prevState) => ({
    data: [...prevState.data.slice(0,index), ...prevState.data.slice(index+1)]
  }))
}

Hope this contributes!!

<hr> is not from struts. It is just an HTML tag.

So, take a look here: http://www.microbion.co.uk/web/vertline.htm This link will give you a couple of tips.

It is not possible to get the users computer name with Javascript. You can get all details about the browser and network. But not more than that.

Like some one answered in one of the previous question today.

I already did a favor of visiting your website, May be I will return or refer other friends.. I also told you where I am and what OS, Browser and screen resolution I use Why do you want to know the color of my underwear? ;-)

You cannot do it using asp.net as well.

Python 3.6 and newer have literal string interpolation using f-strings:

name='world'
print(f"Hello {name}!")

I added the complete code below to display images in Gmail,Thunderbird and other email clients :

MailMessage mailWithImg = getMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!

private MailMessage getMailWithImg()
{
    MailMessage mail = new MailMessage();
    mail.IsBodyHtml = true;
    mail.AlternateViews.Add(getEmbeddedImage("c:/image.png"));
    mail.From = new MailAddress("yourAddress@yourDomain");
    mail.To.Add("recipient@hisDomain");
    mail.Subject = "yourSubject";
    return mail;
}
private AlternateView getEmbeddedImage(String filePath)
 {
    // below line was corrected to include the mediatype so it displays in all 
    // mail clients. previous solution only displays in Gmail the inline images 
    LinkedResource res = new LinkedResource(filePath, MediaTypeNames.Image.Jpeg);  
    res.ContentId = Guid.NewGuid().ToString();
    string htmlBody = @"<img src='cid:" + res.ContentId + @"'/>";
    AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody,  
     null, MediaTypeNames.Text.Html);
    alternateView.LinkedResources.Add(res);
    return alternateView;
}

I resolved this issue by setting an email address in Git:

git config --global user.email "[email protected]"

Try using TempData:

public ActionResult Create(FormCollection collection) {
  ...
  TempData["notice"] = "Successfully registered";
  return RedirectToAction("Index");
  ...
}

Then, in your Index view, or master page, etc., you can do this:

<% if (TempData["notice"] != null) { %>
  <p><%= Html.Encode(TempData["notice"]) %></p>
<% } %>

Or, in a Razor view:

@if (TempData["notice"] != null) {
  <p>@TempData["notice"]</p>
}

Quote from MSDN (page no longer exists as of 2014, archived copy here):

An action method can store data in the controller's TempDataDictionary object before it calls the controller's RedirectToAction method to invoke the next action. The TempData property value is stored in session state. Any action method that is called after the TempDataDictionary value is set can get values from the object and then process or display them. The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request.

Here's a couple of extension methods I've jury-rigged together to convert IQueryables and IEnumerables from one type to another (i.e. DTO). It's mainly used to convert from a larger type (i.e. the type of the row in the database that has unneeded fields) to a smaller one.

The positive sides of this approach are:

• it requires almost no code to use - a simple call to .Transform<DtoType>() is all you need
• it works just like .Select(s=>new{...}) i.e. when used with IQueryable it produces the optimal SQL code, excluding Type1 fields that DtoType doesn't have.

LinqHelper.cs:

public static IQueryable<TResult> Transform<TResult>(this IQueryable source)
{
    var resultType = typeof(TResult);
    var resultProperties = resultType.GetProperties().Where(p => p.CanWrite);

    ParameterExpression s = Expression.Parameter(source.ElementType, "s");

    var memberBindings =
        resultProperties.Select(p =>
            Expression.Bind(typeof(TResult).GetMember(p.Name)[0], Expression.Property(s, p.Name))).OfType<MemberBinding>();

    Expression memberInit = Expression.MemberInit(
        Expression.New(typeof(TResult)),
        memberBindings
        );

    var memberInitLambda = Expression.Lambda(memberInit, s);

    var typeArgs = new[]
        {
            source.ElementType, 
            memberInit.Type
        };

    var mc = Expression.Call(typeof(Queryable), "Select", typeArgs, source.Expression, memberInitLambda);

    var query = source.Provider.CreateQuery<TResult>(mc);

    return query;
}

public static IEnumerable<TResult> Transform<TResult>(this IEnumerable source)
{
    return source.AsQueryable().Transform<TResult>();
}

Right(A1, Len(A1)-Find("(asterisk)",Substitute(A1, "(space)","(asterisk)",Len(A1)-Len(Substitute(A1,"(space)", "(no space)")))))

Try this. Hope it works.

I've never had a problem with doing it like this:

<form>
  <div>
    <input type="checkbox" id="cb" /> <label for="cb">Label text</label>
  </div>
</form>

null = True

Means there is no constraint of database for the field to be filled, so you can have an object with null value for the filled that has this option.

blank = True

Means there is no constraint of validation in django forms. so when you fill a modelForm for this model you can leave field with this option unfilled.

<?php
$str = 'bla_string_bla_bla_bla';
echo preg_replace('/bla_/', '', $str, 1); 
?>

The possible reason can also be that you have not inherited Controller from ApiController. Happened with me took a while to understand the same.

I had trouble with the existing answers when using multidimensional arrays. This solution works for me.

if (is_array($array)) {
    foreach ($array as $key => $val) {
        $array[$key] = trim($val);
    }
}

No. Apps can only modify files within the documents directory, within their own sandbox. This is for security, and ease of installing/uninstalling. So you could only do this on a jailbroken device.

Find *.pem file and place it to the anchors sub-directory or just simply link the *.pem file to there.

yum install -y ca-certificates
update-ca-trust force-enable
sudo ln -s /etc/ssl/your-cert.pem /etc/pki/ca-trust/source/anchors/your-cert.pem
update-ca-trust

Try gzipping some data through the gzip libary like this...

import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content)
f.close()

... then run your code as posted ...

import gzip
f=gzip.open('Onlyfinnaly.log.gz','rb')
file_content=f.read()
print file_content

This method worked for me as for some reason the gzip library fails to read some files.

Hide the body initially, and then show it with jQuery after it has loaded.

body {
    display: none;
}

$(function () {
    $('body').show();
}); // end ready

Also, it would be best to have $('body').show(); as the last line in your last and main .js file.

In my case it was just caused because there was not enough space on the disk for cvtres.exe to write the files it had to.

The error was preceded by this line

CVTRES : fatal error CVT1106: cannot write to file

Building of off an earlier example, I think there is a cleaner way of doing this. Create an index.html file in your project and using Stephen's code from above, just convert it into an HTML doc.

<!DOCTYPE html>
<html>
  <base target="_top">
  <script>
    function onSuccess(url) {
      var a = document.createElement("a"); 
      a.href = url;
      a.target = "_blank";
      window.close = function () {
        window.setTimeout(function() {
          google.script.host.close();
        }, 9);
      };
      if (document.createEvent) {
        var event = document.createEvent("MouseEvents");
        if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) {
          window.document.body.append(a);
        }                        
        event.initEvent("click", true, true); 
        a.dispatchEvent(event);
      } else {
        a.click();
      }
      close();
    }

    function onFailure(url) {
      var div = document.getElementById('failureContent');
      var link = '<a href="' + url + '" target="_blank">Process</a>';
      div.innerHtml = "Failure to open automatically: " + link;
    }

    google.script.run.withSuccessHandler(onSuccess).withFailureHandler(onFailure).getUrl();
  </script>
  <body>
    <div id="failureContent"></div>
  </body>
  <script>
    google.script.host.setHeight(40);
    google.script.host.setWidth(410);
  </script>
</html>

Then, in your Code.gs script, you can have something like the following,

function getUrl() {
  return 'http://whatever.com';
}

function openUrl() {
  var html = HtmlService.createHtmlOutputFromFile("index");
  html.setWidth(90).setHeight(1);
  var ui = SpreadsheetApp.getUi().showModalDialog(html, "Opening ..." );
}

For narrowing the type of the property, simple extend works perfect, as in Nitzan's answer:

interface A {
    x: string | number;
}

interface B extends A {
    x: number;
}

For widening, or generally overriding the type, you can do Zskycat's solution:

interface A {
    x: string
}

export type B = Omit<A, 'x'> & { x: number };

But, if your interface A is extending a general interface, you will lose the custom types of A's remaining properties when using Omit.

e.g.

interface A extends Record<string | number, number | string | boolean> {
    x: string;
    y: boolean;
}

export type B = Omit<A, 'x'> & { x: number };

let b: B = { x: 2, y: "hi" }; // no error on b.y! 

The reason is, Omit internally only goes over Exclude<keyof A, 'x'> keys which will be the general string | number in our case. So, B would become {x: number; } and accepts any extra property with the type of number | string | boolean.

To fix that, I came up with a different OverrideProps utility type as following:

type OverrideProps<M, N> = { [P in keyof M]: P extends keyof N ? N[P] : M[P] };

Example:

type OverrideProps<M, N> = { [P in keyof M]: P extends keyof N ? N[P] : M[P] };

interface A extends Record<string | number, number | string | boolean> {
    x: string;
    y: boolean;
}

export type B = OverrideProps<A, { x: number }>;

let b: B = { x: 2, y: "hi" }; // error: b.y should be boolean!

I just restarted Visual Studio and did IISRESET which solved the problem.

I was looking for the same answer, and I have come up with this solution for PHP 5.3 or later:

$dtz = new DateTimeZone("Europe/Madrid"); //Your timezone
$now = new DateTime(date("Y-m-d"), $dtz);
echo $now->format("Y-m-d H:i:s");

It's creating the file in the same directory as your script. Try this instead.

$content = "some text here";
$fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/myText.txt","wb");
fwrite($fp,$content);
fclose($fp);

Try this:

SELECT
    od.Sku,
    od.mf_item_number,
    od.Qty,
    od.Price,
    s.SupplierId,
    s.SupplierName,
    s.DropShipFees,
    si.Price as cost
FROM
    OrderDetails od
    INNER JOIN Supplier s on s.SupplierId = od.Mfr_ID
    INNER JOIN Group_Master gm on gm.Sku = od.Sku
    INNER JOIN Supplier_Item si on si.SKU = od.Sku and si.SupplierId = s.SupplierID
WHERE
    od.invoiceid = '339740'

This will return multiple rows that are identical except for the cost column. Look at the different cost values that are returned and figure out what is causing the different values. Then ask somebody which cost value they want, and add the criteria to the query that will select that cost.

Clear the dictionary before adding any items to it. I don't know how a dictionary of one object affects another's during assignment but I got the error after creating another object with the same key,value pairs.

NB: If you are going to add items in a loop just make sure you clear the dictionary before entering the loop.

Primary keys always need to be unique, foreign keys need to allow non-unique values if the table is a one-to-many relationship. It is perfectly fine to use a foreign key as the primary key if the table is connected by a one-to-one relationship, not a one-to-many relationship. If you want the same user record to have the possibility of having more than 1 related profile record, go with a separate primary key, otherwise stick with what you have.

I don't think it's enough merely to get the response. I think you need to read it (get the entity and read it via EntityUtils.consume()).

e.g. (from the doc)

     System.out.println("<< Response: " + response.getStatusLine());
     System.out.println(EntityUtils.toString(response.getEntity()));

Can't we use

<properties>
    <my.variable>${env.MY_VARIABLE}</my.variable>
</properties>

There is no need to add if{}else{} control flow. Initialise the button texts for different states at the View or ViewController constructor:

[btnCheckButton setTitle:@"Normal" forState:UIControlStateNormal];
[btnCheckButton setTitle:@"Selected" forState:UIControlStateSelected];

Then switch the button state to Selected:

[btnCheckButton setSelected:YES];

Then switch the button state to Normal:

[btnCheckButton setSelected:NO];

It appears that your package manager failed to create the database named $user for you. The reason that

psql -d template1

works for you is that template1 is a database created by postgres itself, and is present on all installations. You are apparently able to log in to template1, so you must have some rights assigned to you by the database. Try this at a shell prompt:

createdb

and then see if you can log in again with

psql -h localhost

This will simply create a database for your login user, which I think is what you are looking for. If createdb fails, then you don't have enough rights to make your own database, and you will have to figure out how to fix the homebrew package.

FLOAT stores floating point numbers with accuracy up to eight places and has four bytes while DOUBLE stores floating point numbers with accuracy upto 18 places and has eight bytes.

The simplest syntax to redirect both is:

command &> logfile

If you want to append to the file instead of overwrite:

command &>> logfile

I got this error because I didn't specify the correct programmer in the avrdude command line. You have to specify "-c arduino" if you are using an Arduino board.

This example command reads the status of the hfuse:

avrdude -c arduino -P /dev/ttyACM0 -p atmega328p -U hfuse:r:-:h

This solve my problem.

Just change the Bundle identifier from Build Setting.

 Navigate to Project >> Build Setting >> Product Bundle Identifier 

Android Studio Version 2.3

You can create a Service without a Main Activity by following a few easy steps. You'll be able to install this app through Android Studio and debug it like a normal app.

First, create a project in Android Studio without an activity. Then create your Service class and add the service to your AndroidManifest.xml

<application android:allowBackup="true"
    android:label="@string/app_name"
    android:icon="@mipmap/ic_launcher"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <service android:name="com.whatever.myservice.MyService">
        <intent-filter>
            <action android:name="com.whatever.myservice.MyService" />
        </intent-filter>
    </service>
</application>

Now, in the drop down next to the "Run" button(green arrow), go to "edit configurations" and within the "Launch Options" choose "Nothing". This will allow you to install your Service without Android Studio complaining about not having a Main Activity.

Once installed, the service will NOT be running but you will be able to start it with this adb shell command...

am startservice -n com.whatever.myservice/.MyService

Can check it's running with...

ps | grep whatever

I haven't tried yet but you can likely have Android Studio automatically start the service too. This would be done in that "Edit Configurations" menu.

How about using %/sprintf:

i = 20
"%x" % i  #=> "14"

Try this and tell my if it works hope it help you:

string value = Convert.ToString(Console.ReadLine());

Switch(value)
{
    Case "abc":

    break;

    default:

    break;
}       

The others gave examples how to do this in pure python. If you want to do this with arrays with 100.000 elements, you should use numpy:

In [1]: import numpy as np
In [2]: vector1 = np.array([1, 2, 3])
In [3]: vector2 = np.array([4, 5, 6])

Doing the element-wise addition is now as trivial as

In [4]: sum_vector = vector1 + vector2
In [5]: print sum_vector
[5 7 9]

just like in Matlab.

Timing to compare with Ashwini's fastest version:

In [16]: from operator import add
In [17]: n = 10**5
In [18]: vector2 = np.tile([4,5,6], n)
In [19]: vector1 = np.tile([1,2,3], n)
In [20]: list1 = [1,2,3]*n
In [21]: list2 = [4,5,6]*n
In [22]: timeit map(add, list1, list2)
10 loops, best of 3: 26.9 ms per loop

In [23]: timeit vector1 + vector2
1000 loops, best of 3: 1.06 ms per loop

So this is a factor 25 faster! But use what suits your situation. For a simple program, you probably don't want to install numpy, so use standard python (and I find Henry's version the most Pythonic one). If you are into serious number crunching, let numpy do the heavy lifting. For the speed freaks: it seems that the numpy solution is faster starting around n = 8.

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

Use Str() Function. It takes three arguments(the number, the number total characters to display, and the number of decimal places to display

  Select Str(12345.6789, 12, 3)

displays: ' 12345.679' ( 3 spaces, 5 digits 12345, a decimal point, and three decimal digits (679). - it rounds if it has to truncate, (unless the integer part is too large for the total size, in which case asterisks are displayed instead.)

for a Total of 12 characters, with 3 to the right of decimal point.

Layout:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar_top"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="@color/action_bar_bkgnd"
    app:theme="@style/ToolBarTheme" >

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

Code:

    Toolbar mToolbar = parent.findViewById(R.id.toolbar_top);
    TextView mToolbarCustomTitle = parent.findViewById(R.id.toolbar_title);

    //setup width of custom title to match in parent toolbar
    mToolbar.postDelayed(new Runnable()
    {
        @Override
        public void run ()
        {
            int maxWidth = mToolbar.getWidth();
            int titleWidth = mToolbarCustomTitle.getWidth();
            int iconWidth = maxWidth - titleWidth;

            if (iconWidth > 0)
            {
                //icons (drawer, menu) are on left and right side
                int width = maxWidth - iconWidth * 2;
                mToolbarCustomTitle.setMinimumWidth(width);
                mToolbarCustomTitle.getLayoutParams().width = width;
            }
        }
    }, 0);

there is a limited alternative you can use

header:

class std_int_vector;

class A{
    std_int_vector* vector;
public:
    A();
    virtual ~A();
};

cpp:

#include "header.h"
#include <vector>
class std_int_vector: public std::vectror<int> {}

A::A() : vector(new std_int_vector()) {}
[...]

not tested in real programs, so expect it to be non-perfect.

From the many answers I could read, the only given way was to expand the number of variables according to the number of factors. If you have a variable "pet" with levels "dog" and "cat", you would end up with pet_dog and pet_cat.

In my case I wanted to stay with the same number of variables, by just translating the factor variable to a numeric one, in a way that can applied to many variables with many levels, so that cat=1 and dog=0 for instance.

Please find the corresponding solution below:

crime <- data.frame(city = c("SF", "SF", "NYC"),
                    year = c(1990, 2000, 1990),
                    crime = 1:3)

indx <- sapply(crime, is.factor)

crime[indx] <- lapply(crime[indx], function(x){ 
  listOri <- unique(x)
  listMod <- seq_along(listOri)
  res <- factor(x, levels=listOri)
  res <- as.numeric(res)
  return(res)
}
)

my solution is

navigationText: ["", ""]

full code is below:

    var owl1 = $("#main-demo");
    owl1.owlCarousel({
        navigation: true, // Show next and prev buttons
        slideSpeed: 300,
        pagination:false,
        singleItem: true, transitionStyle: "fade",
        navigationText: ["", ""]
    });// Custom Navigation Events

    owl1.trigger('owl.play', 4500);

This should give you a list of all the tables in your database

SELECT Distinct TABLE_NAME FROM information_schema.TABLES

So you can use it similar to your database check.

If NOT EXISTS(SELECT Distinct TABLE_NAME FROM information_schema.TABLES Where TABLE_NAME = 'Your_Table')
BEGIN
    --CREATE TABLE Your_Table
END
GO

str.match(/.{3}/g); // => ['abc', 'def', 'ghi', 'jkl']

The answer is to DISABLE "Enable auto-completion on each input". Tested and works perfectly.

Here's another way of doing it, remember to use free() on the result.

char* wchar_to_char(const wchar_t* pwchar)
{
    // get the number of characters in the string.
    int currentCharIndex = 0;
    char currentChar = pwchar[currentCharIndex];

    while (currentChar != '\0')
    {
        currentCharIndex++;
        currentChar = pwchar[currentCharIndex];
    }

    const int charCount = currentCharIndex + 1;

    // allocate a new block of memory size char (1 byte) instead of wide char (2 bytes)
    char* filePathC = (char*)malloc(sizeof(char) * charCount);

    for (int i = 0; i < charCount; i++)
    {
        // convert to char (1 byte)
        char character = pwchar[i];

        *filePathC = character;

        filePathC += sizeof(char);

    }
    filePathC += '\0';

    filePathC -= (sizeof(char) * charCount);

    return filePathC;
}

Solution for linux with apt-get (eg.: Ubuntu, Debian)

I have quite similar problem. I obtained error:

Error: Could not find an installed version of Gradle either in Android Studio,
or on your system to install the gradle wrapper. Please include gradle 
in your path, or install Android Studi

but without Exception. I solved it on Ubuntu by

sudo apt-get install gradle

I found also commands that allows install newest version of gradle in Ubuntu. It works only when first command is executed before (probably some dependecies are incorrect).

sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle-ppa

https://wtanaka.com/node/8079

If it does not work, try:

export PATH=$PATH:/opt/gradle/gradle-3.5/bin

More info:

For CentOS

Instruction of instalation gradle for CentOS is under this link

https://gist.github.com/parzonka/9371885

Update

Now I installing gradle by sdkman it is something like nvm for node.

Install sdkman

curl -s "https://get.sdkman.io" | bash 

Install gradle

sdk install gradle 4.0.2

If you use PowerPivot and PivotChart, you will exclude non-existing rows.

I added a "Height" to my ListBox and it added the scrollbar nicely.

Sol 1: In build.gradle:

defaultConfig {
    multiDexEnabled true
}

Clean your project and rebuild.

Sol 2: in local.properties add,

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

Sol 3

compile 'com.android.support:multidex:1.0.1'

Else add all 3 in your application.

For lazy people, like me, a snippet based on Nikhil's solution

<input id=username type="text" placeholder="github username or repo link">_x000D_
<button onclick="fetch(`https://api.github.com/users/${username.value.replace(/^.*com[/]([^/]*).*$/,'$1')}/events/public`).then(e=> e.json()).then(e => [...new Set([].concat.apply([],e.filter(x => x.type==='PushEvent').map(x => x.payload.commits.map(c => c.author.email)))).values()]).then(x => results.innerText = x)">GO</button>_x000D_
<div id=results></div>

You need to use %2.6f instead of %f in your printf statement

$(".myButtonClass").css(["border:none; background-color:white; padding:0"]);

As far as I can tell this will only work on newer versions of Android, so you will probably have to figure out a different way to do it. This solution works for me on 4.4, but not on 4.0 or 2.3.3, so this will not be a useful way to go about sharing content for an app that's meant to run on any Android device.

In manifest.xml:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.myapp.SharingActivity"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Take careful note of how you specify the authorities. You must specify the activity from which you will create the URI and launch the share intent, in this case the activity is called SharingActivity. This requirement is not obvious from Google's docs!

file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="just_a_name" path=""/>
</paths>

Be careful how you specify the path. The above defaults to the root of your private internal storage.

In SharingActivity.java:

Uri contentUri = FileProvider.getUriForFile(getActivity(),
"com.mydomain.myapp.SharingActivity", myFile);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("image/jpeg");
shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "Share with"));

In this example we are sharing a JPEG image.

Finally it is probably a good idea to assure yourself that you have saved the file properly and that you can access it with something like this:

File myFile = getActivity().getFileStreamPath("mySavedImage.jpeg");
if(myFile != null){
    Log.d(TAG, "File found, file description: "+myFile.toString());
}else{
    Log.w(TAG, "File not found!");
}

Add the following as the first code:

Properties prop = new Properties();
prop.setProperty("log4j.rootLogger", "WARN");
PropertyConfigurator.configure(prop);

You can use regular multiple expressions with the use of OR (|) operator.

function validateDate(date){
    var regex=new RegExp("([0-9]{4}[-](0[1-9]|1[0-2])[-]([0-2]{1}[0-9]{1}|3[0-1]{1})|([0-2]{1}[0-9]{1}|3[0-1]{1})[-](0[1-9]|1[0-2])[-][0-9]{4})");
    var dateOk=regex.test(date);
    if(dateOk){
        alert("Ok");
    }else{
        alert("not Ok");
    }
}

Above function can validate YYYY-MM-DD, DD-MM-YYYY date formats. You can simply extend the regular expression to validate any date format. Assume you want to validate YYYY/MM/DD, just replace "[-]" with "[-|/]". This expression can validate dates to 31, months to 12. But leap years and months ends with 30 days are not validated.
