Programs & Examples On #Voice recording

This might be a very late reply but it is working for us. We are using the same gallery provided by Android, just that, we have adjusted the left margin such a way that the screens left end is considered as Gallery's center. That really worked well for us.

To catch all the event surrounding model changes, can consider using

<input (ngModelChange)="inputFilter($event)"/>

It will detect copy / paste, keyup, any condition that changes the value of the model.

And then:

inputFilter(event: any) {
    const pattern = /[0-9\+\-\ ]/;
    let inputChar = String.fromCharCode(event.charCode);

    if (!pattern.test(inputChar)) {
      // invalid character, prevent input
      event.preventDefault();
    }
}

The Mockito javadoc seems to tell why use doReturn() instead of when() Use doReturn() in those rare occasions when you cannot use Mockito.when(Object).

Beware that Mockito.when(Object) is always recommended for stubbing because it is argument type-safe and more readable (especially when stubbing consecutive calls).

Here are those rare occasions when doReturn() comes handy:

1. When spying real objects and calling real methods on a spy brings side effects

List list = new LinkedList(); List spy = spy(list);

//Impossible: real method is called so spy.get(0) throws IndexOutOfBoundsException (the list is yet empty)

when(spy.get(0)).thenReturn("foo");

//You have to use doReturn() for stubbing: doReturn("foo").when(spy).get(0);

2. Overriding a previous exception-stubbing:

when(mock.foo()).thenThrow(new RuntimeException());

//Impossible: the exception-stubbed foo() method is called so RuntimeException is thrown. when(mock.foo()).thenReturn("bar");

//You have to use doReturn() for stubbing:

doReturn("bar").when(mock).foo(); Above scenarios shows a tradeoff of Mockito's elegant syntax. Note that the scenarios are very rare, though. Spying should be sporadic and overriding exception-stubbing is very rare. Not to mention that in general overridding stubbing is a potential code smell that points out too much stubbing.

One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.

Assuming you can load your data directly into pandas with pandas.read_csv then the following code might be helpful for you.

import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"

As mentioned in the comments, you can also do the assignment to both columns in one shot:

df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'

Note that you'll need pandas version 0.11 or newer to make use of loc for overwrite assignment operations.

Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:

import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"

I just had a similar problem.

The reason was that I was changing a file.aspx.c and had to do a clean rebuild. After that everything worked.

You can either use:

<button onclick="window.history.back()">Back</button>

or..

<button onclick="window.history.go(-1)">Back</button>

The difference, of course, is back() only goes back 1 page but go() goes back/forward the number of pages you pass as a parameter, relative to your current page.

git diff 15dc8 15dce~1

~1 means 'parent', ~2 'grandparent, etc.

You can load both json strings into Python Dictionaries and then combine. This will only work if there are unique keys in each json string.

import json

a = json.loads(jsonStringA)
b = json.loads(jsonStringB)
c = dict(a.items() + b.items())
# or c =  dict(a, **b)

• Navigate to Control Panel > Programs > Programs and Features and repair the IIS Express.
• Restart the visual studio.

To turn on the IIS is not recommended as other comments suggests if you are not using your system as a live server. For development purpose only IIS Express is adequate.

Use the code below. See it working here http://jsfiddle.net/usmanhalalit/3HPz4/

 $(function(){
     $('#name').change(function(){
         $('#name2 option[value=""]').attr('selected','selected');
     });

     $('#name2').change(function(){
         $('#name option[value=""]').attr('selected','selected');
     });
 });

It should be mentioned that using defined to check if a specific field is set in a hash might behave unexpected:

var = {}
if defined? var['unknown']
  puts 'this is unexpected'
end
# will output "this is unexpected"

The syntax is correct here, but defined? var['unknown'] will be evaluated to the string "method", so the if block will be executed

edit: The correct notation for checking if a key exists in a hash would be:

if var.key?('unknown')

Again I suggest Simple and Easy

Its Working Perfect with ajax when user search and select it saves the selected information via ajax

 $("#vendor-brands").select2({
   ajax: {
   url:site_url('general/get_brand_ajax_json'),
  dataType: 'json',
  delay: 250,
  data: function (params) {
  return {
    q: params.term, // search term
    page: params.page
  };
},
processResults: function (data, params) {
  // parse the results into the format expected by Select2
  // since we are using custom formatting functions we do not need to
  // alter the remote JSON data, except to indicate that infinite
  // scrolling can be used
  params.page = params.page || 1;

  return {
    results: data,
    pagination: {
      more: (params.page * 30) < data.total_count
    }
  };
},
cache: true
},
escapeMarkup: function (markup) { return markup; }, // let our custom    formatter work
minimumInputLength: 1,
}).on("change", function(e) {


  var lastValue = $("#vendor-brands option:last-child").val();
  var lastText = $("#vendor-brands option:last-child").text();

  alert(lastValue+' '+lastText);
 });

Your code is creating an array of function pointers. Try

char* a[size];

or

char a[size1][size2];

instead.

Good article here https://github.com/vasanthk/react-bits/blob/master/patterns/27.passing-function-to-setState.md

// assuming this.state.count === 0
this.setState({count: this.state.count + 1});
this.setState({count: this.state.count + 1});
this.setState({count: this.state.count + 1});
// this.state.count === 1, not 3

Solution
this.setState((prevState, props) => ({
  count: prevState.count + props.increment

          return <td key={i}>{this.props.data[c]}</td>;
        }, this);
      }.bind(this);

    return (
      <tr>{ td(this.props.item) }</tr>
    )

This will sove the problem.

Add the runat="server" attribute to the tag, then you can reference it from the codebehind.

I wrote something like this ....

private void frmMain_Load(object sender, EventArgs e)
{
    cboFromCurrency.Items.Clear();
    cboComboBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
    cboComboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
    // Load data in comboBox => cboComboBox1.DataSource = .....
    // Other things
}

private void cboComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    cboComboBox1.DroppedDown = false;
}

That's all (Y)

Git 101:

git is a decentralized version control system. You do not necessary need a server to get up and running with git. Still you might want to do that as it looks cool, right? (It's also useful if you want to work on a single project from multiple computers.)

So to get a "server" running you need to run git init --bare <your_project>.git as this will create an empty repository, which you can then import on your machines without having to muck around in config files in your .git dir.

After this you could clone the repo on your clients as it is supposed to work, but I found that some clients (namely git-gui) will fail to clone a repo that is completely empty. To work around this you need to run cd <your_project>.git && touch <some_random_file> && git add <some_random_file> && git commit && git push origin master. (Note that you might need to configure your username and email for that machine's git if you hadn't done so in the past. The actual commands to run will be in the error message you get so I'll just omit them.)

So at this point you can clone the repository to any machine simply by running git clone <user>@<server>:<relative_path><your_project>.git. (As others have pointed out you might need to prefix it with ssh:// if you use the absolute path.) This assumes that you can already log in from your client to the server. (You'll also get bonus points for setting up a config file and keys for ssh, if you intend to push a lot of stuff to the remote server.)

Some relevant links:
This pretty much tells you what you need to know.
And this is for those who know the basic workings of git but sometimes forget the exact syntax.

Python (until version 3) supports "old-style" and new-style classes. New-style classes are derived from object and are what you are using, and invoke their base class through super(), e.g.

class X(object):
  def __init__(self, x):
    pass

  def doit(self, bar):
    pass

class Y(X):
  def __init__(self):
    super(Y, self).__init__(123)

  def doit(self, foo):
    return super(Y, self).doit(foo)

Because python knows about old- and new-style classes, there are different ways to invoke a base method, which is why you've found multiple ways of doing so.

For completeness sake, old-style classes call base methods explicitly using the base class, i.e.

def doit(self, foo):
  return X.doit(self, foo)

But since you shouldn't be using old-style anymore, I wouldn't care about this too much.

Python 3 only knows about new-style classes (no matter if you derive from object or not).

The compiler declares the variable in a way that makes it highly prone to an error that is often difficult to find and debug, while producing no perceivable benefits.

Your criticism is entirely justified.

I discuss this problem in detail here:

Closing over the loop variable considered harmful

Is there something you can do with foreach loops this way that you couldn't if they were compiled with an inner-scoped variable? or is this just an arbitrary choice that was made before anonymous methods and lambda expressions were available or common, and which hasn't been revised since then?

The latter. The C# 1.0 specification actually did not say whether the loop variable was inside or outside the loop body, as it made no observable difference. When closure semantics were introduced in C# 2.0, the choice was made to put the loop variable outside the loop, consistent with the "for" loop.

I think it is fair to say that all regret that decision. This is one of the worst "gotchas" in C#, and we are going to take the breaking change to fix it. In C# 5 the foreach loop variable will be logically inside the body of the loop, and therefore closures will get a fresh copy every time.

The for loop will not be changed, and the change will not be "back ported" to previous versions of C#. You should therefore continue to be careful when using this idiom.

first you don't need to add the classRules explicitly since required is automatically detected by the jquery.validate plugin. so you can use this code :

1. on form submit , you prevent the default behavior
2. if the form is Invalid stop the execution.
3. else if valid send the ajax request.

$('#form').submit(function (e) {
  e.preventDefault();
  var $form = $(this);

  // check if the input is valid using a 'valid' property
  if (!$form.valid) return false;

  $.ajax({
    type: 'POST',
    url: 'add.php',
    data: $('#form').serialize(),
    success: function (response) {
      $('#answers').html(response);
    },
  });
});

You need to use quote marks.

font-family: "Comic Sans MS", cursive, sans-serif;

Although you really really shouldn't use comic sans. The font has massive stigma attached to it's use; it's not seen as professional at all.

You are free to use one of those.
Basically, you have to evaluate which is the best one to your app. Think about how you will manage the business flow and how to store/manage data preferences.

Think about, how Fragments store garbage data. When you implement the fragment, you have a activity root to fill with fragment(s). So, if your trying to implement a lot of activities with too much fragments, you have to consider performance on your app, coz you're manipulating (coarsely speaks) two context lifecycle, remember the complexity.

Remember: should I use fragments? Why shouldn't I?

regards.

showInventory(player);     // I get the error here.

void showInventory(player& obj) {   // By Johnny :D

this means that player is an datatype and showInventory expect an referance to an variable of type player.

so the correct code will be

  void showInventory(player& obj) {   // By Johnny :D
    for(int i = 0; i < 20; i++) {
        std::cout << "\nINVENTORY:\n" + obj.getItem(i);
        i++;
        std::cout << "\t\t\t" + obj.getItem(i) + "\n";
        i++;
    }
    }

players myPlayers[10];

    std::string toDo() //BY KEATON
    {
    std::string commands[5] =   // This is the valid list of commands.
        {"help", "inv"};

    std::string ans;
    std::cout << "\nWhat do you wish to do?\n>> ";
    std::cin >> ans;

    if(ans == commands[0]) {
        helpMenu();
        return NULL;
    }
    else if(ans == commands[1]) {
        showInventory(myPlayers[0]);     // or any other index,also is not necessary to have an array
        return NULL;
    }

}

Adding and removing tab may be a bit less effective May be this will help

To hide/show tab page => let tabPage1 of tabControl1

tapPage1.Parent = null;            //to hide tabPage1 from tabControl1
tabPage1.Parent = tabControl1;     //to show the tabPage1 in tabControl1

Update with React v16 and ReactRouter v4.2.0 (October 2017):

class BackButton extends Component {
  static contextTypes = {
    router: () => true, // replace with PropTypes.object if you use them
  }

  render() {
    return (
      <button
        className="button icon-left"
        onClick={this.context.router.history.goBack}>
          Back
      </button>
    )
  }
}

Update with React v15 and ReactRouter v3.0.0 (August 2016):

var browserHistory = ReactRouter.browserHistory;

var BackButton = React.createClass({
  render: function() {
    return (
      <button
        className="button icon-left"
        onClick={browserHistory.goBack}>
        Back
      </button>
    );
  }
});

Created a fiddle with a little bit more complex example with an embedded iframe: https://jsfiddle.net/kwg1da3a/

React v14 and ReacRouter v1.0.0 (Sep 10, 2015)

You can do this:

var React = require("react");
var Router = require("react-router");

var SomePage = React.createClass({
  ...

  contextTypes: {
    router: React.PropTypes.func
  },
  ...

  handleClose: function () {
    if (Router.History.length > 1) {
      // this will take you back if there is history
      Router.History.back();
    } else {
      // this will take you to the parent route if there is no history,
      // but unfortunately also add it as a new route
      var currentRoutes = this.context.router.getCurrentRoutes();
      var routeName = currentRoutes[currentRoutes.length - 2].name;
      this.context.router.transitionTo(routeName);
    }
  },
  ...

You need to be careful that you have the necessary history to go back. If you hit the page directly and then hit back it will take you back in the browser history before your app.

This solution will take care of both scenarios. It will, however, not handle an iframe that can navigate within the page (and add to the browser history), with the back button. Frankly, I think that is a bug in the react-router. Issue created here: https://github.com/rackt/react-router/issues/1874

You can fix your example with the iterator pattern by changing the parametrization of the class:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Iterator<Room> i = rooms.iterator(); i.hasNext(); ) {
  String item = i.next();
  System.out.println(item);
}

or much simpler way:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Room room : rooms) {
  System.out.println(room);
}

Using double ampersands will run the second command, only if the first one succeeds:

cd Desktop/project-directory && atom .

Where as, using only one ampersand will attempt to run both commands, even if the first fails:

cd Desktop/project-directory & atom .

private boolean isDuplicate() {
    for (int i = 0; i < arrayList.size(); i++) {
        for (int j = i + 1; j < arrayList.size(); j++) {
            if (arrayList.get(i).getName().trim().equalsIgnoreCase(arrayList.get(j).getName().trim())) {
                return true;
            }
        }
    }

    return false;
}

I use Xcode 4.3.2, and my problem was that in there where a folder inside another folder with the same name, e.g myFolder/myFolder/.

The solution was to change the second folder's name e.g myFolder/_myFolder and the problem was solved.

I hope this can help some one.

You will always have to iterate. Yet you can use Java 8, 9 to do the counting without looping explicitely:

Iterable<Integer> newIterable = () -> iter;
long count = StreamSupport.stream(newIterable.spliterator(), false).count();

Here is a test:

public static void main(String[] args) throws IOException {
    Iterator<Integer> iter = Arrays.asList(1, 2, 3, 4, 5).iterator();
    Iterable<Integer> newIterable = () -> iter;
    long count = StreamSupport.stream(newIterable.spliterator(), false).count();
    System.out.println(count);
}

This prints:

5

Interesting enough you can parallelize the count operation here by changing the parallel flag on this call:

long count = StreamSupport.stream(newIterable.spliterator(), *true*).count();

If you wish to open the batch file in another window, use start. This way, you can basically run two scripts at the same time. In other words, you don't have to wait for the script you just called to finish. All examples below work:

start batch.bat
start call batch.bat
start cmd /c batch.bat

If you want to wait for the script to finish, try start /w call batch.bat, but the batch.bat has to end with exit.

It can be done easily & automatically if that textfield is in a table's cell (even when the table.scrollable = NO).

• NOTE that: the position and size of the table must be reasonable. e.g:
  • if the y position of table is 100 counted from the view's bottom, then the 300 height keyboard will overlap the whole table.
  • if table's height = 10, and the textfield in it must be scrolled up 100 when keyboard appears in order to be visible, then that textfield will be out of the table's bound.

I'll share a code which has Basic Auth Header form data request body,

let username = 'test-name';
let password = 'EbQZB37gbS2yEsfs';
let formdata = new FormData();
let headers = new Headers();


formdata.append('grant_type','password');
formdata.append('username','testname');
formdata.append('password','qawsedrf');

headers.append('Authorization', 'Basic ' + base64.encode(username + ":" + password));
fetch('https://www.example.com/token.php', {
 method: 'POST',
 headers: headers,
 body: formdata
}).then((response) => response.json())
.then((responseJson) => {
 console.log(responseJson);

 this.setState({
    data: responseJson
 })
  })
   .catch((error) => {
 console.error(error);
   });

public class StringToLong {

   public static void main (String[] args) {

      // String s = "fred";    // do this if you want an exception

      String s = "100";

      try {
         long l = Long.parseLong(s);
         System.out.println("long l = " + l);
      } catch (NumberFormatException nfe) {
         System.out.println("NumberFormatException: " + nfe.getMessage());
      }

   }
}

nor does it appear in the list of environments that can be added when I click the "Add" button. All I see is the J2EE Runtime Library.

Go get "Eclipse for Java EE developers". Note the extra "EE". This includes among others the Web Tools Platform with among others a lot of server plugins with among others the one for Apache Tomcat 5.x. It's also logically; JSP/Servlet is part of the Java EE API.

If you need the index of the first occurrence of only one value, you can use nonzero (or where, which amounts to the same thing in this case):

>>> t = array([1, 1, 1, 2, 2, 3, 8, 3, 8, 8])
>>> nonzero(t == 8)
(array([6, 8, 9]),)
>>> nonzero(t == 8)[0][0]
6

If you need the first index of each of many values, you could obviously do the same as above repeatedly, but there is a trick that may be faster. The following finds the indices of the first element of each subsequence:

>>> nonzero(r_[1, diff(t)[:-1]])
(array([0, 3, 5, 6, 7, 8]),)

Notice that it finds the beginning of both subsequence of 3s and both subsequences of 8s:

[1, 1, 1, 2, 2, 3, 8, 3, 8, 8]

So it's slightly different than finding the first occurrence of each value. In your program, you may be able to work with a sorted version of t to get what you want:

>>> st = sorted(t)
>>> nonzero(r_[1, diff(st)[:-1]])
(array([0, 3, 5, 7]),)

Make sure you die() after your redirection, and make sure you do your redirect AS SOON AS POSSIBLE while your script executes. It makes sure that no more database queries (if some) are not wasted for nothing. That's the one tip I can give you

For search engines, 301 is the best response code

Using base R's rep_len:

x <- 1:10
n <- 3

split(x, rep_len(1:n, length(x)))
# $`1`
# [1]  1  4  7 10
# 
# $`2`
# [1] 2 5 8
# 
# $`3`
# [1] 3 6 9

And as already mentioned if you want sorted indices, simply:

split(x, sort(rep_len(1:n, length(x))))
# $`1`
# [1] 1 2 3 4
# 
# $`2`
# [1] 5 6 7
# 
# $`3`
# [1]  8  9 10

I am using in those cases you are referring switch(). It looks like a control statement but actually, it is a function. The expression is evaluated and based on this value, the corresponding item in the list is returned.

switch works in two distinct ways depending whether the first argument evaluates to a character string or a number.

What follows is a simple string example which solves your problem to collapse old categories to new ones.

For the character-string form, have a single unnamed argument as the default after the named values.

newCat <- switch(EXPR = category,
       cat1   = catX,
       cat2   = catX,
       cat3   = catY,
       cat4   = catY,
       cat5   = catZ,
       cat6   = catZ,
       "not available")

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

You do not need to use {{ }} inside of ng-bind-html-unsafe:

<div ng-bind-html-unsafe="preview_data.preview.embed.html"></div>

Here's an example: http://plnkr.co/edit/R7JmGIo4xcJoBc1v4iki?p=preview

The {{ }} operator is essentially just a shorthand for ng-bind, so what you were trying amounts to a binding inside a binding, which doesn't work.

f=open('filename','r').read()
f1=f.split('\n')
for i in range (len(f1)):
    do_something_with(f1[i])

hope this helps.

I was having the same problem just delete .m2 folder folder from your local repositry Hope it will work.

I have successfully implemented simple code for Multiple permission at Once. Follow the below steps 1:Make Utility.java class like below

public class Utility {
public static final int MY_PERMISSIONS_REQUEST = 123;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean checkPermissions(Context context, String... permissions) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, permission)) {
                    ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
                } else {
                    ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
                }
                return false;
            }
        }
    }
    return true;
}
}

2: Now call

boolean permissionCheck = Utility.checkPermissions(this, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CALL_PHONE, Manifest.permission.GET_ACCOUNTS);  

in your Activity onCreate() or according to your logic.

3:Now check permission before performing operation for particular task

if (permissionCheck) {
 performTaskOperation();//this method what you need to perform
} else {
        Toast.makeText(this, "Need permission ON.", Toast.LENGTH_SHORT).show();
       }

4: Now implement onRequestPermissionsResult() method in your Activity as below

  @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case Utility.MY_PERMISSIONS_REQUEST:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                if (userChoosenTask.equals("STORAGE"))
                    performTaskOperation();//this method what you need to perform
            }
            break;
    }
}

function EnableHyperLink(id) {
        $('#' + id).attr('onclick', 'Pagination("' + id + '")');//onclick event which u 
        $('#' + id).addClass('enable-link');
        $('#' + id).removeClass('disable-link');
    }

    function DisableHyperLink(id) {
        $('#' + id).addClass('disable-link');
        $('#' + id).removeClass('enable-link');
        $('#' + id).removeAttr('onclick');
    }

.disable-link
{
    text-decoration: none !important;
    color: black !important;
    cursor: default;
}
.enable-link
{
    text-decoration: underline !important;
    color: #075798 !important;
    cursor: pointer !important;
}

• Open "Repo Browser" (Use Link of yr parent folder) .
• Right click Choose "Add Folder".
• Browse to your folder.

Depends on what you care about. If you mean WALL TIME (as in, the time on the clock on your wall), time.clock() provides NO accuracy because it may manage CPU time.

If you don't want to implement your connector customizer, you can build and import the library (https://github.com/ycavatars/spring-boot-https-kit) which provides predefined connector customizer. According to the README, you only have to create your keystore, configure connector.https.*, import the library and add @ComponentScan("org.ycavatars.sboot.kit"). Then you'll have HTTPS connection.

SSRS will not accept duplicated columns so ensure that your query or store procedure is returning unique column names.

When I had this issue the cause was a relative reference to template files when using the ui.bootstrap.modal module.

templateUrl: 'js/templates/modal.html'

This works from a root domain (www.example.com) but when a path is added (www.example.com/path/) the reference breaks. The answer in my case was simply to making the reference absolute (js/ -> /js/).

templateUrl: '/js/templates/modal.html'

Forget using plt.title and place the text directly with plt.text. An over-exaggerated example is given below:

import pylab as plt

fig = plt.figure(figsize=(5,10))

figure_title = "Normal title"
ax1  = plt.subplot(1,2,1)

plt.title(figure_title, fontsize = 20)
plt.plot([1,2,3],[1,4,9])

figure_title = "Raised title"
ax2  = plt.subplot(1,2,2)

plt.text(0.5, 1.08, figure_title,
         horizontalalignment='center',
         fontsize=20,
         transform = ax2.transAxes)
plt.plot([1,2,3],[1,4,9])

plt.show()

Read Scott Hanselman's post on the issue: http://www.hanselman.com/blog/AReminderOnThreeMultiTierLayerArchitectureDesignBroughtToYouByMyLateNightFrustrations.aspx

Remember though, that in "Scott World" (which is hopefully your world also :) ) a "Tier" is a unit of deployment, while a "Layer" is a logical separation of responsibility within code. You may say you have a "3-tier" system, but be running it on one laptop. You may say your have a "3-layer" system, but have only ASP.NET pages that talk to a database. There's power in precision, friends.

In Java there is nothing at language level similar to ref. In Java there is only passing by value semantic

For the sake of curiosity you can implement a ref-like semantic in Java simply wrapping your objects in a mutable class:

public class Ref<T> {

    private T value;

    public Ref(T value) {
        this.value = value;
    }

    public T get() {
        return value;
    }

    public void set(T anotherValue) {
        value = anotherValue;
    }

    @Override
    public String toString() {
        return value.toString();
    }

    @Override
    public boolean equals(Object obj) {
        return value.equals(obj);
    }

    @Override
    public int hashCode() {
        return value.hashCode();
    }
}

testcase:

public void changeRef(Ref<String> ref) {
    ref.set("bbb");
}

// ...
Ref<String> ref = new Ref<String>("aaa");
changeRef(ref);
System.out.println(ref); // prints "bbb"

For images if your using Web Pages v2 use the WebImage Class

var webImage = new System.Web.Helpers.WebImage(Request.Files[0].InputStream);
byte[] imgByteArray = webImage.GetBytes();

"Then" is a command in bash, thus it needs a ";" or a newline before it.

#!/bin/bash
echo "start\n"
for f in *.jpg
do
  fname=$(basename "$f")
  echo "fname is $fname\n"
  fname="${filename%.*}"
  echo "fname is $fname\n"
  if [$[fname%2] -eq 1 ]
  then
    echo "removing $fname\n"
    rm $f
  fi
done

def rounding(float,precision)
    return ((float * 10**precision).round.to_f) / (10**precision)
end

From my understanding, the currently accepted answer only changes the order of the factor levels, not the actual labels (i.e., how the levels of the factor are called). To illustrate the difference between levels and labels, consider the following example:

Turn cyl into factor (specifying levels would not be necessary as they are coded in alphanumeric order):

    mtcars2 <- mtcars %>% mutate(cyl = factor(cyl, levels = c(4, 6, 8))) 
    mtcars2$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 4 6 8

Change the order of levels (but not the labels itself: cyl is still the same column)

    mtcars3 <- mtcars2 %>% mutate(cyl = factor(cyl, levels = c(8, 6, 4))) 
    mtcars3$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 8 6 4
    all(mtcars3$cyl==mtcars2$cyl)
    #[1] TRUE

Assign new labels to cyl The order of the labels was: c(8, 6, 4), hence we specify new labels as follows:

    mtcars4 <- mtcars3 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_8", 
                                                               "new_value_for_6", 
                                                               "new_value_for_4" )))
    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

Note how this column differs from our first columns:

    all(as.character(mtcars4$cyl)!=mtcars3$cyl) 
    #[1] TRUE 
    #Note: TRUE here indicates that all values are unequal because I used != instead of ==
    #as.character() was required as the levels were numeric and thus not comparable to a character vector

More details:

If we were to change the levels of cyl using mtcars2 instead of mtcars3, we would need to specify the labels differently to get the same result. The order of labels for mtcars2 was: c(4, 6, 8), hence we specify new labels as follows

    #change labels of mtcars2 (order used to be: c(4, 6, 8)
    mtcars5 <- mtcars2 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_4", 
                                                               "new_value_for_6", 
                                                               "new_value_for_8" )))

Unlike mtcars3$cyl and mtcars4$cyl, the labels of mtcars4$cyl and mtcars5$cyl are thus identical, even though their levels have a different order.

    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

    mtcars5$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_4 new_value_for_6 new_value_for_8

    all(mtcars4$cyl==mtcars5$cyl)
    #[1] TRUE

    levels(mtcars4$cyl) == levels(mtcars5$cyl)
    #1] FALSE  TRUE FALSE

Do you have the SSH2 extension available?

Docs: http://www.php.net/manual/en/function.ssh2-exec.php

ssh2_auth_password($connection, 'username', 'password');

$stream = ssh2_exec($connection, '/usr/local/bin/php -i');

I had the same error message and my way to deal with it is as follows:

1. First go check the file directory where your Tomcat is publishing your web application, e.g. D:\Java\workspace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\myDatatable\WEB-INF\classes, in which we normally put our classes. If this is not the place where you put your classes, then you have to find out where by default it is by right click your web application root name-->Build Path-->Configure Build Bath...-->Then check the "Source" Tab and find out the field value of "Default output folder". This shall be the place where Tomcat put your classes.
2. You would see that XYZ class is not yet built. In order to build it, you could go to Menu "Project"-->"Clean..."-->Select your web application to clean.
3. After it's completed, try restart your tomcat server and go check the file directory again. Your class should be there. At least it works for me. Hope it helps.

In case of Oracle since 12c you have DEFAULT ON NULL which implies a NOT NULL constraint.

ALTER TABLE tbl ADD (col VARCHAR(20) DEFAULT ON NULL 'MyDefault');

ALTER TABLE

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified. If you specify an inline constraint that conflicts with NOT NULL and NOT DEFERRABLE, then an error is raised.

Another cause of this could be if you don't use the default variable name for the "id" which is actually: id.

ToolsVersion="4.0" does it for me in my MSBuild project:

<Project DefaultTargets="Do" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

If you need to have jquery use !important for more than one item, this is how you would do it.

e.g. set an img tags max-width and max-height to 500px each

$('img').css('cssText', "max-width: 500px !important;' + "max-height: 500px !important;');

@praneeth-nidarshan has covered mostly all the steps, except some:

• Check if you have pear installed (or install):

$ sudo apt-get install php-pear

• Install, if isn't already installed, php7.2-dev, in order to avoid the error:

sh: phpize: not found

ERROR: `phpize’ failed

$ sudo apt-get install php7.2-dev

• Install mcrypt using pecl:

$ sudo pecl install mcrypt-1.0.1

• Add the extention extension=mcrypt.so to your php.ini configuration file; if you don't know where it is, search with:

$ sudo php -i | grep 'Configuration File'

this happened again around last quarter of 2017 . greasemonkey firing too late . after domcontentloaded event already been fired.

what to do:

• i used @run-at document-start instead of document-end
• updated firefox to 57.

from : https://github.com/greasemonkey/greasemonkey/issues/2769

Even as a (private) script writer I'm confused why my script isn't working.

The most likely problem is that the 'DOMContentLoaded' event is fired before the script is run. Now before you come back and say @run-at document-start is set, that directive isn't fully supported at the moment. Due to the very asynchronous nature of WebExtensions there's little guarantee on when something will be executed. When FF59 rolls around we'll have #2663 which will help. It'll actually help a lot of things, debugging too.

Val is immutable and its properties are set at run time, but you can use a const modifier to make it as a compile time constant. Val in kotlin is same as final in java.

Var is mutable and its type is identified at compile time.

I had the same problem with openCV on Raspberry Pi... don't know if this can solve your problem, but what worked for me was

import time
import cv2


cap = cv2.VideoCapture(0)

cap.set(3,1280)

cap.set(4,1024)

time.sleep(2)

cap.set(15, -8.0)

the time you have to use can be different

SELECT 
    distributor_id, 
    COUNT(*) AS TOTAL, 
    COUNT(IF(level='exec',1,null)),
    COUNT(IF(level='personal',1,null))
FROM sometable;

COUNT only counts non null values and the DECODE will return non null value 1 only if your condition is satisfied.

While the accepted answer is technically correct, a more practical approach, if possible, is to just strip whitespace out of both the regular expression and the search string.

If you want to search for "my cats", instead of:

myString.match(/m\s*y\s*c\s*a\*st\s*s\s*/g)

Just do:

myString.replace(/\s*/g,"").match(/mycats/g)

Warning: You can't automate this on the regular expression by just replacing all spaces with empty strings because they may occur in a negation or otherwise make your regular expression invalid.

A simple view like this was giving me the ORA-01861 error when executed from Entity Framework:

create view myview as 
select * from x where x.initialDate >= '01FEB2021'

Just did something like this to fix it:

create view myview as 
select * from x where x.initialDate >= TO_DATE('2021-02-01', 'YYYY-MM-DD')

I think the problem is EF date configuration is not the same as Oracle's.

This like a trick,

UILabel *customLabel = [[UILabel alloc] init];

UIColor *color = [UIColor blueColor];
customLabel.layer.shadowColor = [color CGColor];
customLabel.layer.shadowRadius = 5.0f;
customLabel.layer.shadowOpacity = 1;
customLabel.layer.shadowOffset = CGSizeZero;
customLabel.layer.masksToBounds = NO;

You probably have an old version of wget. I suggest installing wget using Chocolatey, the package manager for Windows. This should give you a more recent version (if not the latest).

Run this command after having installed Chocolatey (as Administrator):

choco install wget

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

**This can be achived easily using two different ways:**

1)We can also do this by using addClass and removeClass of Jquery
2)Toggle class of jQuery

**1)First Way**

$(documnet.ready(function(){
$('#dvId').click(function(){
  $('#dvId').removeClass('active class or your class name which you want to    remove').addClass('active class or your class name which you want to add');     
});
});

**2) Second Way**

i) Here we need to add the class which we want to show while page get loads.
ii)after clicking on div we we will toggle class i.e. the class is added while loading page gets removed and class which we provide in toggleClss gets added :)

<div id="dvId" class="ActiveClassname ">
</div

$(documnet.ready(function(){
$('#dvId').click(function(){
  $('#dvId').toggleClass('ActiveClassname InActiveClassName');     
});
});


Enjoy.....:)

If you any doubt free to ask any time...

You can do This : $("#td_id").removeClass('Old_class'); $("#td_id").addClass('New_class'); Or You can do This

$("#td_id").removeClass('Old_class').addClass('New_class');

You can also use the \b for a word boundary. For the name I would use something like this:

[^\b]+\b[^\b]+(\b|$)

EDIT Modifying this to be a regex in Perl example

if( $fullname =~ /([^\b]+)\b[^\b]+([^\b]+)(\b|$)/ ) {
 $first_name = $1;
 $last_name = $2;
}

EDIT AGAIN Based on what you want:

$new_tag = preg_replace("/[\s\t]/","",$tag);

Just a note in addition to the other answers.

If an initial value is supplied to reduce then sometimes its type must be specified, viz:-

a.reduce(fn, [])

may have to be

a.reduce<string[]>(fn, [])

or

a.reduce(fn, <string[]>[])

You can't alter the existing columns for identity.

You have 2 options,

Create a new table with identity & drop the existing table

Create a new column with identity & drop the existing column

Approach 1. (New table) Here you can retain the existing data values on the newly created identity column.

CREATE TABLE dbo.Tmp_Names
    (
      Id int NOT NULL
             IDENTITY(1, 1),
      Name varchar(50) NULL
    )
ON  [PRIMARY]
go

SET IDENTITY_INSERT dbo.Tmp_Names ON
go

IF EXISTS ( SELECT  *
            FROM    dbo.Names ) 
    INSERT  INTO dbo.Tmp_Names ( Id, Name )
            SELECT  Id,
                    Name
            FROM    dbo.Names TABLOCKX
go

SET IDENTITY_INSERT dbo.Tmp_Names OFF
go

DROP TABLE dbo.Names
go

Exec sp_rename 'Tmp_Names', 'Names'

Approach 2 (New column) You can’t retain the existing data values on the newly created identity column, The identity column will hold the sequence of number.

Alter Table Names
Add Id_new Int Identity(1, 1)
Go

Alter Table Names Drop Column ID
Go

Exec sp_rename 'Names.Id_new', 'ID', 'Column'

RightClick on any Project->Create New Other ->Web Services->Web Service Client->Then paste the wsdl url(or location) in Service Definition->Next->Finish

You will see the generated classes are inside your src folder.

NOTE :Without eclipse also you can generate client classes from wsdl file by using wsimport command utility which ships with JDK.

refer this link Create Web service client using wsdl

It's always worth grouping elements into sections that are relevant. In your case, a parent element that contains two columns;

1. icon
2. text.

http://jsfiddle.net/qMdfC/10/

HTML:

<div class='container2'>
    <img src='http://ecx.images-amazon.com/images/I/21-leKb-zsL._SL500_AA300_.png' class='iconDetails' />

    <div class="text">
        <h4>Facebook</h4>
        <p>
            fine location, GPS, coarse location
            <span>0 mins ago</span>
        </p>
    </div>
</div>

CSS:

* {
    padding:0;
    margin:0;
}
.iconDetails {
    margin:0 2%;
    float:left;
    height:40px;
    width:40px;
}
.container2 {
    width:100%;
    height:auto;
    padding:1%;
}
.text {
    float:left;
}
.text h4, .text p {
    width:100%;
    float:left;
    font-size:0.6em;
}
.text p span {
    color:#666;
}

Try this:

<a onclick='$("#notification").fadeOut(300, function() { $(this).remove(); });' class="notificationClose "><img src="close.png"/></a>

I think your double quotes around the onclick were making it not work. :)

EDIT: As pointed out below, inline javascript is evil and you should probably take this out of the onclick and move it to jQuery's click() event handler. That is how the cool kids are doing it nowadays.

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

You can use JSON.parse() (which is a built in function that will probably force you to wrap it with try-catch statements).

Or use some JSON parsing npm library, something like json-parse-or

For VB.NET developers Use this generic sub to mark the child state, easy to use

Notes:

• PromatCon: the entity object
• amList: is the child list that you want to add or modify
• rList: is the child list that you want to remove

updatechild(objCas.ECC_Decision, PromatCon.ECC_Decision.Where(Function(c) c.rid = objCas.rid And Not objCas.ECC_Decision.Select(Function(x) x.dcid).Contains(c.dcid)).toList)

Sub updatechild(Of Ety)(amList As ICollection(Of Ety), rList As ICollection(Of Ety))
        If amList IsNot Nothing Then
            For Each obj In amList
                Dim x = PromatCon.Entry(obj).GetDatabaseValues()
                If x Is Nothing Then
                    PromatCon.Entry(obj).State = EntityState.Added
                Else
                    PromatCon.Entry(obj).State = EntityState.Modified
                End If
            Next
        End If

        If rList IsNot Nothing Then
            For Each obj In rList.ToList
                PromatCon.Entry(obj).State = EntityState.Deleted
            Next
        End If
End Sub

PromatCon.SaveChanges()

The library has a section in the readme about escaping. It's Javascript-native, so I do not suggest switching to node-mysql-native. The documentation states these guidelines for escaping:

Edit: node-mysql-native is also a pure-Javascript solution.

• Numbers are left untouched
• Booleans are converted to true / false strings
• Date objects are converted to YYYY-mm-dd HH:ii:ss strings
• Buffers are converted to hex strings, e.g. X'0fa5'
• Strings are safely escaped
• Arrays are turned into list, e.g. ['a', 'b'] turns into 'a', 'b'
• Nested arrays are turned into grouped lists (for bulk inserts), e.g. [['a', 'b'], ['c', 'd']] turns into ('a', 'b'), ('c', 'd')
• Objects are turned into key = 'val' pairs. Nested objects are cast to strings.
• undefined / null are converted to NULL
• NaN / Infinity are left as-is. MySQL does not support these, and trying to insert them as values will trigger MySQL errors until they implement support.

This allows for you to do things like so:

var userId = 5;
var query = connection.query('SELECT * FROM users WHERE id = ?', [userId], function(err, results) {
  //query.sql returns SELECT * FROM users WHERE id = '5'
});

As well as this:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  //query.sql returns INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
});

Aside from those functions, you can also use the escape functions:

connection.escape(query);
mysql.escape(query);

To escape query identifiers:

mysql.escapeId(identifier);

And as a response to your comment on prepared statements:

From a usability perspective, the module is great, but it has not yet implemented something akin to PHP's Prepared Statements.

The prepared statements are on the todo list for this connector, but this module at least allows you to specify custom formats that can be very similar to prepared statements. Here's an example from the readme:

connection.config.queryFormat = function (query, values) {
  if (!values) return query;
  return query.replace(/\:(\w+)/g, function (txt, key) {
    if (values.hasOwnProperty(key)) {
      return this.escape(values[key]);
    }
    return txt;
  }.bind(this));
};

This changes the query format of the connection so you can use queries like this:

connection.query("UPDATE posts SET title = :title", { title: "Hello MySQL" });
//equivalent to
connection.query("UPDATE posts SET title = " + mysql.escape("Hello MySQL");

In the event CellContentClick you can use this strategy:

private void myDataGrid_CellContentClick(object sender, DataGridViewCellEventArgs e)
{    
    if (e.ColumnIndex == 2)//set your checkbox column index instead of 2
    {   //When you check
        if (Convert.ToBoolean(myDataGrid.Rows[e.RowIndex].Cells[2].EditedFormattedValue) == true)
        {
            //EXAMPLE OF OTHER CODE
            myDataGrid.Rows[e.RowIndex].Cells[5].Value = DateTime.Now.ToShortDateString();

            //SET BY CODE THE CHECK BOX
            myDataGrid.Rows[e.RowIndex].Cells[2].Value = 1;
        }
        else //When you decheck
        {
            myDataGrid.Rows[e.RowIndex].Cells[5].Value = String.Empty;

            //SET BY CODE THE CHECK BOX
            myDataGrid.Rows[e.RowIndex].Cells[2].Value = 0;
        }
    }
}

You can do this with repositories that have been crawled by Google (results vary from repository to repository).

Search all branches of all crawled repositories for "change license"

"change license" site:https://github.com/*/*/commits

Search master branch of all crawled repositories for "change license":

"change license" site:https://github.com/*/*/commits/master

Search master branch of all crawled twitter repositories for "change license"

"change license" site:https://github.com/twitter/*/commits/master

Search all branches of twitter/some_project repository for "change license"

"change license" site:https://github.com/twitter/some_project/commits

Don't use "\n". Just try this:

var string = "this\
is a multi\
line\
string";

Just enter a back-slash and keep on truckin'! Works like a charm.

just building on what Chetabahana wrote, I found that adding a short delay to the JS function helped on a site I was working on. It meant that the function kicked in after the iframe loaded. You can play around with the delay.

var delayInMilliseconds = 500; // half a second

setTimeout(function() { 

   var iframe = document.getElementsByTagName('iframe')[0];
   iframe.style.background = 'white';
   iframe.contentWindow.document.body.style.backgroundColor = 'white';

}, delayInMilliseconds);

I hope this helps!

The DateTimeOffset structure was created for exactly this type of use.

See: http://msdn.microsoft.com/en-us/library/system.datetimeoffset.aspx

Here's an example of creating a DateTimeOffset object with a specific time zone:

DateTimeOffset do1 = new DateTimeOffset(2008, 8, 22, 1, 0, 0, new TimeSpan(-5, 0, 0));

The values are determined by the bit of the image. 8 bit 0 to 255

16 bit...some ridiculous number..0 to 65,000 approx.

32 bit are 0 to 1

I use .004 with 32 bit images...this gives 1.02 as a result when multiplied by 255

As a rephrasing of Andrey's answer:

The Boost TypeIndex library can be used to print names of types.

Inside a template, this might read as follows

#include <boost/type_index.hpp>
#include <iostream>

template<typename T>
void printNameOfType() {
    std::cout << "Type of T: " 
              << boost::typeindex::type_id<T>().pretty_name() 
              << std::endl;
}

Per Josh Bloch - Item 65: Don't ignore Exceptions of Effective Java:

1. An empty catch block defeats the purpose of exceptions
2. At the very least, the catch block should contain a comment explaining why it is appropriate to ignore the exception.

Either your data is bad, or it's not structured the way you think it is. Possibly both.

To prove/disprove this hypothesis, run this query:

SELECT * from
(
    SELECT count(*) as c, Supplier_Item.SKU
    FROM Supplier_Item
    INNER JOIN orderdetails
        ON Supplier_Item.sku = orderdetails.sku
    INNER JOIN Supplier
        ON Supplier_item.supplierID = Supplier.SupplierID
    GROUP BY Supplier_Item.SKU
) x
WHERE c > 1
ORDER BY c DESC

If this returns just a few rows, then your data is bad. If it returns lots of rows, then your data is not structured the way you think it is. (If it returns zero rows, I'm wrong.)

I'm guessing that you have orders containing the same SKU multiple times (two separate line items, both ordering the same SKU).

For this to work in Chrome the value must not have another pair of quotes.

It only works, for example, like this:

$('a[data-customerID=22]');

Add Thread.sleep

try {
        Thread.sleep(3000);
    } catch(InterruptedException ie) {}

import java.util.*;
public class MyFirstJava {
public static void main(String[] args)
{
  Animal dog = new Animal();
  dog.Info("Dog","Breezi","Lab","Chicken liver");
  dog.Getname();
  Animal dog2= new Animal();
  dog2.Info("Dog", "pumpkin", "POM", "Pedigree");
  dog2.Getname();
  HashMap<String,  HashMap<String, Object>> dogs = new HashMap<>();
  dogs.put("dog1", new HashMap<>() {{put("Name",dog.name); 
  put("Food",dog.food);put("Age",3);}});
  dogs.put("dog2", new HashMap<>() {{put("Name",dog2.name); 
  put("Food",dog2.food);put("Age",6);}});
  //dogs.get("dog1");
  System.out.print(dogs + "\n");
  System.out.print(dogs.get("dog1").get("Age"));

} }

Just set the height and width where you are adding that logo. I tried and its working fine

Until the day #pragma once becomes standard (that's not currently a priority for the future standards), I suggest you use it AND use guards, this way:

#ifndef BLAH_H
#define BLAH_H
#pragma once

// ...

#endif

The reasons are :

• #pragma once is not standard, so it is possible that some compiler don't provide the functionality. That said, all major compiler supports it. If a compiler don't know it, at least it will be ignored.
• As there is no standard behavior for #pragma once, you shouldn't assume that the behavior will be the same on all compiler. The guards will ensure at least that the basic assumption is the same for all compilers that at least implement the needed preprocessor instructions for guards.
• On most compilers, #pragma once will speed up compilation (of one cpp) because the compiler will not reopen the file containing this instruction. So having it in a file might help, or not, depending on the compiler. I heard g++ can do the same optimization when guards are detected but it have to be confirmed.

Using the two together you get the best of each compiler for this.

Now, if you don't have some automatic script to generate the guards, it might be more convenient to just use #pragma once. Just know what that means for portable code. (I'm using VAssistX to generate the guards and pragma once quickly)

You should almost always think your code in a portable way (because you don't know what the future is made of) but if you really think that it's not meant to be compiled with another compiler (code for very specific embedded hardware for example) then you should just check your compiler documentation about #pragma once to know what you're really doing.

No, you never call the base class destructor, it is always called automatically like others have pointed out but here is proof of concept with results:

class base {
public:
    base()  { cout << __FUNCTION__ << endl; }
    ~base() { cout << __FUNCTION__ << endl; }
};

class derived : public base {
public:
    derived() { cout << __FUNCTION__ << endl; }
    ~derived() { cout << __FUNCTION__ << endl; } // adding call to base::~base() here results in double call to base destructor
};


int main()
{
    cout << "case 1, declared as local variable on stack" << endl << endl;
    {
        derived d1;
    }

    cout << endl << endl;

    cout << "case 2, created using new, assigned to derive class" << endl << endl;
    derived * d2 = new derived;
    delete d2;

    cout << endl << endl;

    cout << "case 3, created with new, assigned to base class" << endl << endl;
    base * d3 = new derived;
    delete d3;

    cout << endl;

    return 0;
}

The output is:

case 1, declared as local variable on stack

base::base
derived::derived
derived::~derived
base::~base


case 2, created using new, assigned to derive class

base::base
derived::derived
derived::~derived
base::~base


case 3, created with new, assigned to base class

base::base
derived::derived
base::~base

Press any key to continue . . .

If you set the base class destructor as virtual which one should, then case 3 results would be same as case 1 & 2.

You could simply look in the Active Record Rake tasks as that is where I believe they live as in this file. https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/lib/active_record/tasks/database_tasks.rb

What they do is your question right?

That depends on where they come from and this is just and example to show that they vary depending upon the task. Here we have a different file full of tasks.

https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/Rakefile

which has these tasks.

namespace :db do
  task create: ["db:mysql:build", "db:postgresql:build"]
  task drop: ["db:mysql:drop", "db:postgresql:drop"]
end

This may not answer your question but could give you some insight into go ahead and look the source over especially the rake files and tasks. As they do a pretty good job of helping you use rails they don't always document the code that well. We could all help there if we know what it is supposed to do.

You don't really need a specific client, it's fairly simple with most libraries. For example in jQuery you can just call the generic $.ajax function with the type of request you want to make:

$.ajax({
    url: 'http://example.com/',
    type: 'PUT',
    data: 'ID=1&Name=John&Age=10', // or $('#myform').serializeArray()
    success: function() { alert('PUT completed'); }
});

You can replace PUT with GET/POST/DELETE or whatever.

You could give Benchmark.js a try. It supports many platforms among them also node.js.

Lots of the answers here don't honor changes of the table or are way too complicated. Using a subclass of UITableView that will properly set intrinsicContentSize is a far easier solution when using autolayout. No height constraints etc. needed.

class UIDynamicTableView: UITableView
{
    override var intrinsicContentSize: CGSize {
        self.layoutIfNeeded()
        return CGSize(width: UIViewNoIntrinsicMetric, height: self.contentSize.height)
    }

    override func reloadData() {
        super.reloadData()
        self.invalidateIntrinsicContentSize()
    }
} 

Set the class of your TableView to UIDynamicTableView in the interface builder and watch the magic as this TableView will change it's size after a call to reloadData().

Easy, as long as your filenames don't include newlines:

find . -maxdepth 1

If you're piping this into another command, you should probably prefer to separate your filenames by null bytes, rather than newlines, since null bytes cannot occur in a filename (but newlines may):

find . -maxdepth 1 -print0

Printing that on a terminal will probably display as one line, because null bytes are not normally printed. Some programs may need a specific option to handle null-delimited input, such as sort's -z. Your own script similarly would need to account for this.

There is no way to display interactive elements on the lockscreen or wallpaper with a non jailbroken iPhone.

I would recommend Countdown Widget it's free an you can display countdowns in the notification center which you can also access from your lockscreen.

To change your password for accessing Subversion

Typically this would be handled by your Subversion server administrator. If that's you and you are using the built-in authentication, then edit your [repository]\conf\passwd file on your Subversion server machine.

To delete locally-cached credentials

Follow these steps:

• Right-click your desktop and select TortoiseSVN->Settings
• Select Saved Data.
• Click Clear against Authentication Data.

Next time you attempt an action that requires credentials you'll be asked for them.

If you're using the command-line svn.exe use the --no-auth-cache option so that you can specify alternate credentials without having them cached against your Windows user.

I haven't had a problem just using Unix-style path separators, even on Windows (though it is good practice to check File.separatorChar).

The technique of using ClassLoader.getResource() is best for read-only resources that are going to be loaded from JAR files. Sometimes, you can programmatically determine the application directory, which is useful for admin-configurable files or server applications. (Of course, user-editable files should be stored somewhere in the System.getProperty("user.home") directory.)

Think of @Html.Partial as HTML code copied into the parent page. Think of @Html.RenderPartial as an .ascx user control incorporated into the parent page. An .ascx user control has far more overhead.

'@Html.Partial' returns a html encoded string that gets constructed inline with the parent. It accesses the parent's model.

'@Html.RenderPartial' returns the equivalent of a .ascx user control. It gets its own copy of the page's ViewDataDictionary and changes made to the RenderPartial's ViewData do not effect the parent's ViewData.

Using reflection we find:

public static MvcHtmlString Partial(this HtmlHelper htmlHelper, string partialViewName, object model, ViewDataDictionary viewData)
{
    MvcHtmlString mvcHtmlString;
    using (StringWriter stringWriter = new StringWriter(CultureInfo.CurrentCulture))
    {
        htmlHelper.RenderPartialInternal(partialViewName, viewData, model, stringWriter, ViewEngines.Engines);
        mvcHtmlString = MvcHtmlString.Create(stringWriter.ToString());
    }
    return mvcHtmlString;
}

public static void RenderPartial(this HtmlHelper htmlHelper, string partialViewName)
{
    htmlHelper.RenderPartialInternal(partialViewName, htmlHelper.ViewData, null, htmlHelper.ViewContext.Writer, ViewEngines.Engines);
}

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))

Of course, you should modify this sample script based on your own application.

Reinstallation will works because it will reset all the value to default. It is better to find what the real culprits (my.cnf editing mistake does happens, e.g. bad/outdated parameter suggestion during mysql tuning.)

Here is the mysql diagnosis if you suspect some value is wrong inside my.cnf : Run the mysqld to show you the results.

sudo -u mysql  mysqld 

Afterwards, fix all the my.cnf key error that pop out from the screen until mysqld startup successfully.

Then restart it using

sudo service mysql restart

For debug/release flags, see the CMAKE_BUILD_TYPE variable (you pass it as cmake -DCMAKE_BUILD_TYPE=value). It takes values like Release, Debug, etc.

https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/Useful-Variables#compilers-and-tools

cmake uses the extension to choose the compiler, so just name your files .c.

You can override this with various settings:

For example:

set_source_files_properties(yourfile.c LANGUAGE CXX) 

Would compile .c files with g++. The link above also shows how to select a specific compiler for C/C++.

Java 8 Style for a given date

LocalDate today = LocalDate.of(1982, Month.AUGUST, 31);
System.out.println(today.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(Locale.ENGLISH)));
System.out.println(today.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(Locale.FRENCH)));
System.out.println(today.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(Locale.JAPANESE)));

I think you are misinterpreting the source of the error; rExternalTotal appears to be equal to a single cell. rReportData.offset(0,0) is equal to rReportData
rReportData.offset(261,0).end(xlUp) is likely also equal to rReportData, as you offset by 261 rows and then use the .end(xlUp) function which selects the top of a contiguous data range.
If you are interested in the sum of just a column, you can just refer to the whole column:

dExternalTotal = Application.WorksheetFunction.Sum(columns("A:A"))

or

dExternalTotal = Application.WorksheetFunction.Sum(columns((rReportData.column))

The worksheet function sum will correctly ignore blank spaces.

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

The Simulator does not run ARM code, ONLY x86 code. Unless you have the raw source code from Apple, you won't see the App Store on the Simulator.

The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account. To test your app on an actual device, you will need to be apart of the Apple Developer program.

i have resolved this by following steps.

1) Go to customise icon in the top right corner chrome.
2) click on more tools option.
3) Click task manager.
4) Kill/end process GPU process

This has resolved my issue of black screen in chrome.

You can pass in the hostname as an environment variable. You could also mount /etc so you can cat /etc/hostname. But I agree with Vitaly, this isn't the intended use case for containers IMO.

So with the code you have provided.

var bytes = Convert.FromBase64String(resizeImage.Content);
using (var imageFile = new FileStream(filePath, FileMode.Create))
{
    imageFile.Write(bytes ,0, bytes.Length);
    imageFile.Flush();
}

above answers In simple words, you have to register under @NgModule's

declarations: [
    AppComponent, YourNewComponentHere
  ] 

of app.module.ts

do not forget to import that component.

You can revert only one file to a specified revision.

First you can check on which commits the file was changed.

git log path/to/file.txt

Then you can checkout the file with the revision number.

git checkout 3cdc61015724f9965575ba954c8cd4232c8b42e4 /path/to/file.txt

After that you can commit and push it again.

Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.

Do you have this:

use Cartalyst\Sentry\Sentry; 

In your code?

Ok, but if this line is working for you:

$user = $this->sentry->register(array(     'username' => e($data['username']),     'email' => e($data['email']),      'password' => e($data['password'])     )); 

So you already have it instantiated and you can surely do:

$adminGroup = $this->sentry->findGroupById(5);

This exception can raise when you handle Deep linking or URL for a browser, if there is no default installed. In case of Deep linking there may be no application installed that can process a link in format myapp://mylink.

You can use the tangerine solution for API up to 29:

private fun openUrl(url: String) {
    val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
    val activityInfo = intent.resolveActivityInfo(packageManager, intent.flags)
    if (activityInfo?.exported == true) {
        startActivity(intent)
    } else {
        Toast.makeText(
            this,
            "No application that can handle this link found",
            Toast.LENGTH_SHORT
        ).show()
    }
}

For API >= 30 see intent.resolveActivity returns null in API 30.

Supposing the list may be long and the numbers may repeat, consider using the SortedList type from the Python sortedcontainers module. The SortedList type will automatically maintain the tuples in order by number and allow for fast searching.

For example:

from sortedcontainers import SortedList
sl = SortedList([(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")])

# Get the index of 53:

index = sl.bisect((53,))

# With the index, get the tuple:

tup = sl[index]

This will work a lot faster than the list comprehension suggestion by doing a binary search. The dictionary suggestion will be faster still but won't work if there could be duplicate numbers with different strings.

If there are duplicate numbers with different strings then you need to take one more step:

end = sl.bisect((53 + 1,))

results = sl[index:end]

By bisecting for 54, we will find the end index for our slice. This will be significantly faster on long lists as compared with the accepted answer.

<content>(?:[^\n]*(\n+))+</content>

Another way is to use CONCATand CAST, be aware, that you need to use DATETIME2(x) to make it work. You can set x to anything between 0-7 7 meaning no precision loss.

DECLARE @date date = '2018-03-12'
DECLARE @time time = '07:00:00.0000000'
SELECT CAST(CONCAT(@date, ' ', @time) AS DATETIME2(7))

Returns 2018-03-12 07:00:00.0000000

First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.

If not you have some compilation errors in your java classes.

There are several ways to convert SVG to PNG using the Canvg library.

In my case, I needed to get the PNG blob from inline SVG.

The library documentation provides an example (see OffscreenCanvas example).

But this method does not work at the moment in Firefox. Yes, you can enable the gfx.offscreencanvas.enabled option in the settings. But will every user on the site do this? :)

However, there is another way that will work in Firefox too.

const el = document.getElementById("some-svg"); //this is our inline SVG

var canvas = document.createElement('canvas'); //create a canvas for the SVG render
canvas.width = el.clientWidth; //set canvas sizes
canvas.height = el.clientHeight;

const svg = new XMLSerializer().serializeToString(el); //convert SVG to string

//render SVG inside canvas
const ctx = canvas.getContext('2d');
const v = await Canvg.fromString(ctx, svg);
await v.render();

let canvasBlob = await new Promise(resolve => canvas.toBlob(resolve));

You should not map score to player. You should map player (or his name) to score:

Map<Player, Integer> player2score = new HashMap<Player, Integer>();

Then add players to map: int score = .... Player player = new Player(); player.setName("John"); // etc. player2score.put(player, score);

In this case the task is trivial:

int score = player2score.get(player);

1. Go to the developers console and pick the application from the dropdown
2. Select the utilities icon (see image below) and click project settings
3. Click on the the Delete Project link
4. Enter the project ID and click Shutdown, project will be deleted in 7 days

    $object = new stdClass();
    $object->id = 1;

    $object2 = new stdClass();
    $object2->id = 2;

    $objects = [
        $object,
        $object2
    ];

    $ids = array_map(function ($object) {
        /** @var YourEntity $object */
        return $object->id;
        // Or even if you have public methods
        // return $object->getId()
    }, $objects);

If the any of values of the request's JSON object are not the same type as expected by the service then the [FromBody] argument will be null.

For example, if the age property in the json had a float value:

"age":18.0

but the API service expects it to be an int

"age":18

then student will be null. (No error messages will be sent in the response unless no null reference check).

Starting from Java 10:

Set<E> oldSet = Set.of();
Set<E> newSet = Set.copyOf(oldSet);

Set.copyOf() returns an unmodifiable Set containing the elements of the given Collection.

The given Collection must not be null, and it must not contain any null elements.

Try

$("#deliveryNext").is('[disabled]');

The python manual provides the following:

import termios, fcntl, sys, os
fd = sys.stdin.fileno()

oldterm = termios.tcgetattr(fd)
newattr = termios.tcgetattr(fd)
newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
termios.tcsetattr(fd, termios.TCSANOW, newattr)

oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

try:
    while 1:
        try:
            c = sys.stdin.read(1)
            print "Got character", repr(c)
        except IOError: pass
finally:
    termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
    fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

which can be rolled into your use case.

I needed something like this for a game's control configuration UI, so I compiled a list for the standard US keyboard layout keycodes and mapped them to their respective key names.

Here's a fiddle that contains a map for code -> name and visi versa: http://jsfiddle.net/vWx8V/

If you want to support other key layouts you'll need to modify these maps to accommodate for them separately.

That is unless you were looking for a list of keycode values that included the control characters and other special values that are not (or are rarely) possible to input using a keyboard and may be outside of the scope of the keydown/keypress/keyup events of Javascript. Many of them are control characters or special characters like null (\0) and you most likely won't need them.

Notice that the number of keys on a full keyboard is less than many of the keycode values.

Just see the below code snippet if you are implementing a REST API through express and mongoose. (Example for ADD)

...._x000D_
exports.AddSomething = (req,res,next) =>{_x000D_
  const newSomething = new SomeEntity({_x000D_
 _id:new mongoose.Types.ObjectId(), //its very own ID_x000D_
  somethingName:req.body.somethingName,_x000D_
  theForeignKey: mongoose.Types.ObjectId(req.body.theForeignKey)// if you want to pass an object ID_x000D_
})_x000D_
}_x000D_
...

Hope it Helps

This code seems completely unnecessary:

String serverURLS = getRecipientURL(message);

serverURLS = "https:\\\\abc.my.domain.com:55555\\update";

if (serverURLS != null){
    serverURL = new URL(serverURLS);
}

1. serverURLS is assigned the result of getRecipientURL(message)
2. Then immediately you overwrite the value of serverURLS, making the previous statement a dead store
3. Then, because if (serverURLS != null) evaluates to true, since you just assigned the variable a value in the preceding statement, you assign a value to serverURL. It is impossible for if (serverURLS != null) to evaluate to false!
4. You never actually use the variable serverURLS beyond the previous line of code.

You could replace all of this with just:

serverURL = new URL("https:\\\\abc.my.domain.com:55555\\update");

You need to put package-info.java in your generated jaxb package. Its content should be something like that

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.org/StudentOperations/")
package generated.marsh;

For those who are using Visual Studio 2017 version, it seems like the preprocessor definition required to run unsafe operations has changed. Use instead:

#define _CRT_SECURE_NO_WARNINGS

It will compile then.

Ubuntu, which is a Debian derivative, follows a very precise structure when installing packages. In other words, all software installed through the packaging tools, such as apt-get or synaptic, will put the stuff in the same locations. If you become familiar with these locations, you'll always know where to find your stuff.

As a short cut, you can always open a tool like synaptic, find the installed package, and inspect the "properties". Under properties, you'll see a list of all installed files. Again, you can expect these to always follow the Debian/Ubuntu conventions; these are highly ordered Linux distributions. IN short, binaries will be in /usr/bin, or some other location on your path ( try 'echo $PATH' on the command line to see the possible locations ). Configuration is always in a subdirectory of /etc. And the "home" is typically in /usr/lib or /usr/share.

For instance, according to http://www.mkyong.com/maven/how-to-install-maven-in-ubuntu/, maven is installed like:

The Apt-get installation will install all the required files in the following folder structure

/usr/bin/mvn

/usr/share/maven2/

/etc/maven2

P.S The Maven configuration is store in /etc/maven2

Note, it's not just apt-get that will do this, it's any .deb package installer.

From some reason most of the answers here didn't help me (maybe it's related to my FROM image in the Dockerfile)

So I preferred to create a bash script in my workspace combined with --build-arg in order to handle if statement while Docker build by checking if the argument is empty or not

Bash script:

#!/bin/bash -x

if test -z $1 ; then 
    echo "The arg is empty"
    ....do something....
else 
    echo "The arg is not empty: $1"
    ....do something else....
fi

Dockerfile:

FROM ...
....
ARG arg
COPY bash.sh /tmp/  
RUN chmod u+x /tmp/bash.sh && /tmp/bash.sh $arg
....

Docker Build:

docker build --pull -f "Dockerfile" -t $SERVICE_NAME --build-arg arg="yes" .

Remark: This will go to the else (false) in the bash script

docker build --pull -f "Dockerfile" -t $SERVICE_NAME .

Remark: This will go to the if (true)

Edit 1:

After several tries I have found the following article and this one which helped me to understand 2 things:

1) ARG before FROM is outside of the build

2) The default shell is /bin/sh which means that the if else is working a little bit different in the docker build. for example you need only one "=" instead of "==" to compare strings.

So you can do this inside the Dockerfile

ARG argname=false   #default argument when not provided in the --build-arg
RUN if [ "$argname" = "false" ] ; then echo 'false'; else echo 'true'; fi

and in the docker build:

docker build --pull -f "Dockerfile" --label "service_name=${SERVICE_NAME}" -t $SERVICE_NAME --build-arg argname=true .

NumPy 1.7.0 (when numpy.pad was added) is pretty old now (it was released in 2013) so even though the question asked for a way without using that function I thought it could be useful to know how that could be achieved using numpy.pad.

It's actually pretty simple:

>>> import numpy as np
>>> a = np.array([[ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.]])
>>> np.pad(a, [(0, 1), (0, 1)], mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In this case I used that 0 is the default value for mode='constant'. But it could also be specified by passing it in explicitly:

>>> np.pad(a, [(0, 1), (0, 1)], mode='constant', constant_values=0)
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

Just in case the second argument ([(0, 1), (0, 1)]) seems confusing: Each list item (in this case tuple) corresponds to a dimension and item therein represents the padding before (first element) and after (second element). So:

[(0, 1), (0, 1)]
         ^^^^^^------ padding for second dimension
 ^^^^^^-------------- padding for first dimension

  ^------------------ no padding at the beginning of the first axis
     ^--------------- pad with one "value" at the end of the first axis.

In this case the padding for the first and second axis are identical, so one could also just pass in the 2-tuple:

>>> np.pad(a, (0, 1), mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In case the padding before and after is identical one could even omit the tuple (not applicable in this case though):

>>> np.pad(a, 1, mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Or if the padding before and after is identical but different for the axis, you could also omit the second argument in the inner tuples:

>>> np.pad(a, [(1, ), (2, )], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

However I tend to prefer to always use the explicit one, because it's just to easy to make mistakes (when NumPys expectations differ from your intentions):

>>> np.pad(a, [1, 2], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Here NumPy thinks you wanted to pad all axis with 1 element before and 2 elements after each axis! Even if you intended it to pad with 1 element in axis 1 and 2 elements for axis 2.

I used lists of tuples for the padding, note that this is just "my convention", you could also use lists of lists or tuples of tuples, or even tuples of arrays. NumPy just checks the length of the argument (or if it doesn't have a length) and the length of each item (or if it has a length)!

foreach over a statement is just a syntax sugar for the regular one-way fetch() loop. If you want to loop over your data more than once, select it as a regular array first

$sql = "SELECT * FROM users";
$stm = $dbh->query($sql);
// here you go:
$users = $stm->fetchAll();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Also quit that try..catch thing. Don't use it, but set the proper error reporting for PHP and PDO

I've just solved the problem.I found that the nodes in the App.config file have configed wrong.

Confirm your config in the node <security>,the attribute "mode" value is "None". If your value is "Transport",the error occurs.

You want to create a "Dynamic Web Project". Follow the steps here: Spring MVC Tutorial with Eclipse and Tomcat.

I dont get it clearly, do you want to link an external css as the structure of files you defined above? If yes then just use the link tag :

    <link rel="stylesheet" type="text/css" href="file.css">

so basically for files that are under your website folder (folder containing your index) you directly call it. For each successive folder use the "/" for example in your case :

    <link rel="stylesheet" type="text/css" href="Fonts/Font1/file name">
    <link rel="stylesheet" type="text/css" href="Fonts/Font2/file name">

When you ask about:

Blockquote // But what now? How do I display my data? Blockquote

you need to map an array of object, that way:

response([{label: 'result_name', value: 'result_id'},]);

That way when you use the select event of the autocomplete plugin, you can see the result bellow;

You can use the select event that way:

jQuery("#field").autocomplete({
      source: function (request, response) {

Install Python package without Admin rights

import sys

!{sys.executable} -m pip install package_name

Example

import sys

!{sys.executable} -m pip install kivy

Reference: https://docs.python.org/3.4/library/sys.html#sys.executable

First we need to know on the range of microseconds i.e. 000_000 to 999_999 (1000000 microseconds is equal to 1second). tv.tv_usec will return value from 0 to 999999 not 000000 to 999999 so when using it with seconds we might get 2.1seconds instead of 2.000001 seconds because when only talking about tv_usec 000001 is essentially 1. Its better if you insert

if(tv.tv_usec<10)
{
 printf("00000");
} 
else if(tv.tv_usec<100&&tv.tv_usec>9)// i.e. 2digits
{
 printf("0000");
}

and so on...

guys. I had the same problem before when I'm trying import a .aar package into my project, and unfortunately before make the .aar package as a module-dependence of my project, I had two modules (one about ROS-ANDROID-CV-BRIDGE, one is OPENCV-FOR-ANDROID) already. So, I got this error as you guys meet:

Error:Could not find method android() for arguments [org.ros.gradle_plugins.RosAndroidPlugin$_apply_closure2_closure4@7e550e0e] on project ‘:xxx’ of type org.gradle.api.Project.

So, it's the painful gradle-structure caused this problem when you have several modules in your project, and worse, they're imported in different way or have different types (.jar/.aar packages or just a project of Java library). And it's really a headache matter to make the configuration like compile-version, library dependencies etc. in each subproject compatible with the main-project.

I solved my problem just follow this steps:

? Copy .aar package in app/libs.

? Add this in app/build.gradle file:

repositories {
    flatDir {
        dirs 'libs' //this way we can find the .aar file in libs folder
    }
}

? Add this in your add build.gradle file of the module which you want to apply the .aar dependence (in my situation, just add this in my app/build.gradle file):

dependencies {
    compile(name:'package_name', ext:'aar')
}

So, if it's possible, just try export your module-dependence as a .aar package, and then follow this way import it to your main-project. Anyway, I hope this can be a good suggestion and would solve your problem if you have the same situation with me.

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories, and it should work.

The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

So, answering my own question here. We ultimately determined that we were seeing 502 and 503 errors in the load balancer due to Tomcat threads timing out. In the short term we increased the timeout. In the longer term, we fixed the app problems that were causing the timeouts in the first place. Why Tomcat timeouts were being perceived as 502 and 503 errors at the load balancer is still a bit of a mystery.

Two more

The First one

>>> births = str(5)
>>> print("there are " + births + " births.")
there are 5 births.

When adding strings, they concatenate.

The Second One

Also the format (Python 2.6 and newer) method of strings is probably the standard way:

>>> births = str(5)
>>>
>>> print("there are {} births.".format(births))
there are 5 births.

This format method can be used with lists as well

>>> format_list = ['five', 'three']
>>> # * unpacks the list:
>>> print("there are {} births and {} deaths".format(*format_list))  
there are five births and three deaths

or dictionaries

>>> format_dictionary = {'births': 'five', 'deaths': 'three'}
>>> # ** unpacks the dictionary
>>> print("there are {births} births, and {deaths} deaths".format(**format_dictionary))
there are five births, and three deaths

If you take 5 minutes to download visual studio and make a Console Application for this, your problem is solved.

using System;
using System.Linq;
using System.Diagnostics;
using System.IO;

namespace BgRunner
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Starting: " + String.Join(" ", args));
            String arguments = String.Join(" ", args.Skip(1).ToArray());
            String command = args[0];

            Process p = new Process();
            p.StartInfo = new ProcessStartInfo(command);
            p.StartInfo.Arguments = arguments;
            p.StartInfo.WorkingDirectory = Path.GetDirectoryName(command);
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.UseShellExecute = false;
            p.Start();
        }
    }
}

Examples of usage:

BgRunner.exe php/php-cgi -b 9999
BgRunner.exe redis/redis-server --port 3000
BgRunner.exe nginx/nginx

If you have created multiple worktrees with git worktree, you'll need to run git prune before you can delete the branch

There actually IS a way to do it in Python 2.3+, but it's a bit esoteric. I don't know if you realize this, but you can do the following:

$ unzip -l /tmp/example.zip
 Archive:  /tmp/example.zip
   Length     Date   Time    Name
 --------    ----   ----    ----
     8467  11-26-02 22:30   jwzthreading.py
 --------                   -------
     8467                   1 file
$ ./python
Python 2.3 (#1, Aug 1 2003, 19:54:32) 
>>> import sys
>>> sys.path.insert(0, '/tmp/example.zip')  # Add .zip file to front of path
>>> import jwzthreading
>>> jwzthreading.__file__
'/tmp/example.zip/jwzthreading.py'

According to the zipimport library:

Any files may be present in the ZIP archive, but only files .py and .py[co] are available for import. ZIP import of dynamic modules (.pyd, .so) is disallowed. Note that if an archive only contains .py files, Python will not attempt to modify the archive by adding the corresponding .pyc or .pyo file, meaning that if a ZIP archive doesn't contain .pyc files, importing may be rather slow.

Thus, all you have to do is zip the files up, add the zipfile to your sys.path and then import them.

If you're building this for UNIX, you might also consider packaging your script using this recipe: unix zip executable, but note that you might have to tweak this if you plan on using stdin or reading anything from sys.args (it CAN be done without too much trouble).

In my experience performance doesn't suffer too much because of this, but you should think twice before importing any very large modules this way.

.bar {
background - color: blue;
height: 40 px;
width: 40 px;
border - style: solid;
border - right - width: 1300 px;
border - radius: 40 px;
animation - name: Load;
animation - duration: 11 s;
position: relative;
animation - iteration - count: 1;
animation - fill - mode: forwards;
}

@keyframes Load {
100 % {
    width: 1300 px;border - right - width: 5;
}

I'd say it depends upon the size of your project... Personnally, I would use Maven for simple projects that need straightforward compiling, packaging and deployment. As soon as you need to do some more complicated things (many dependencies, creating mapping files...), I would switch to Ant...

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

It is worth to note that it's possible to add Q expressions.

For example:

from django.db.models import Q

query = Q(first_name='mark')
query.add(Q(email='[email protected]'), Q.OR)
query.add(Q(last_name='doe'), Q.AND)

queryset = User.objects.filter(query)

This ends up with a query like :

(first_name = 'mark' or email = '[email protected]') and last_name = 'doe'

This way there is no need to deal with or operators, reduce's etc.

Just your passing your dateformate and your date then you get Year,month,day,hour. Extra info

func GetOnlyDateMonthYearFromFullDate(currentDateFormate:NSString , conVertFormate:NSString , convertDate:NSString ) -> NSString
    {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = currentDateFormate as String
        let formatter = NSDateFormatter()
        formatter.dateFormat = Key_DATE_FORMATE as String
        let finalDate = formatter.dateFromString(convertDate as String)
        formatter.dateFormat = conVertFormate as String
        let dateString = formatter.stringFromDate(finalDate!)

        return dateString
    }

Get Year

let Year = self.GetOnlyDateMonthYearFromFullDate("yyyy-MM-dd'T'HH:mm:ssZ", conVertFormate: "YYYY", convertDate: "2016-04-14T10:44:00+0000") as String

Get Month

let month = self.GetOnlyDateMonthYearFromFullDate("yyyy-MM-dd'T'HH:mm:ssZ", conVertFormate: "MM", convertDate: "2016-04-14T10:44:00+0000") as String

Get Day

let day = self.GetOnlyDateMonthYearFromFullDate("yyyy-MM-dd'T'HH:mm:ssZ", conVertFormate: "dd", convertDate: "2016-04-14T10:44:00+0000") as String

Get Hour

let hour  = self.GetOnlyDateMonthYearFromFullDate("yyyy-MM-dd'T'HH:mm:ssZ", conVertFormate: "hh", convertDate: "2016-04-14T10:44:00+0000") as String

This is how you should setup Eclipse Debugger for remote debugging:

Eclipse Settings:

1.Click the Run Button
2.Select the Debug Configurations
3.Select the “Remote Java Application”
4.New Configuration

• Name : GatewayPortalProject
• Project : GatewayPortal-portlet
• Connection Type: Socket Attach
• Connection Properties: i) localhost ii) 8787

For JBoss:

1.Change the /path/toJboss/jboss-eap-6.1/bin/standalone.conf in your vm as follows: Uncomment the following line by removing the #:

JAVA_OPTS="$JAVA_OPTS -agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n"

For Tomcat :

In catalina.bat file :

Step 1:

CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"

Step 2:

JPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"

Step 3: Run Tomcat from command prompt like below:

catalina.sh jpda start

Then you need to set breakpoints in the Java classes you desire to debug.

JsonLint is good for validating and formatting JSON.

If you are a Windows user, this is a common error when you use XAMPP since LDAP is not enabled by default.

You can follow this steps to make sure LDAP works in your XAMPP:

• [Your Drive]:\xampp\php\php.ini: In this file uncomment the following line:

   extension=php_ldap.dll
  

• Move the file: libsasl.dll, from [Your Drive]:\xampp\php to [Your Drive]:\xampp\apache\bin (Note: moving the file is needed only for XAMPP prior to version: 5.6.28)

• Restart Apache.

• You can now use functions of the LDAP Module!

If you use Linux:

For php5:

sudo apt-get install php5-ldap

For php7:

sudo apt-get install php7.0-ldap

If you are using the latest version of PHP you can do

sudo apt-get install php-ldap

running the above command should do the trick.

if for any reason it doesn't work check your php.ini configuration to enable ldap, remove the semicolon before extension=ldap to uncomment, save and restart Apache

On Windows gvim just select "Lucida Console" font.

Thanks for pointing toward the correct answer.

I have just checked the Golang FAQ (duh) and it clearly states, this is not available in the language:

Does Go have the ?: operator?

There is no ternary form in Go. You may use the following to achieve the same result:

if expr {
    n = trueVal
} else {
    n = falseVal
}

Check your system clock,

$ date

If it's not correct the certificate check will fail. To correct the system clock,

$ apt-get install ntp

The clock should synchronise itself.

Finally enter the clone command again.

In Bash you can check if Imagick is an installed module:

$ php -m | grep imagick

If the response is blank it is not installed.

Using React.createRef()

class MessageBox extends Component {
        constructor(props) {
            super(props)
            this.boxRef = React.createRef()
        }

        scrollToBottom = () => {
            this.boxRef.current.scrollTop = this.boxRef.current.scrollHeight
        }

        componentDidUpdate = () => {
            this.scrollToBottom()
        }

        render() {
            return (
                        <div ref={this.boxRef}></div>
                    )
        }
}

You can also use AWK which can give you more flexibility to handle the file

awk '{ print "chmod 755 "$0"" | "/bin/sh"}' file.txt

if your file has a field separator like:

field1,field2,field3

To get only the first field you do

awk -F, '{ print "chmod 755 "$1"" | "/bin/sh"}' file.txt

Try this:

INSERT INTO table1 SELECT "A string", 5, idTable2 FROM table2 WHERE ...

Try using private browsing in Safari or deleting your entire cache/cookies.

I've had some similar issues using chrome when the browser thought it had the website in its cache but actually had not.

The part of the http request that makes the server respond a 304 is the etag. Seems like Safari is sending the right etag without having the corresponding cache.

Original response:

array=(a c b "f f" 3 5)
readarray -t sorted < <(for a in "${array[@]}"; do echo "$a"; done | sort)

output:

$ for a in "${sorted[@]}"; do echo "$a"; done
3
5
a
b
c
f f

Note this version copes with values that contains special characters or whitespace (except newlines)

Note readarray is supported in bash 4+.

Edit Based on the suggestion by @Dimitre I had updated it to:

readarray -t sorted < <(printf '%s\0' "${array[@]}" | sort -z | xargs -0n1)

which has the benefit of even understanding sorting elements with newline characters embedded correctly. Unfortunately, as correctly signaled by @ruakh this didn't mean the the result of readarray would be correct, because readarray has no option to use NUL instead of regular newlines as line-separators.

Override toString() method in Student class as below:

   @Override
   public String toString() {
        return ("StudentName:"+this.getStudentName()+
                    " Student No: "+ this.getStudentNo() +
                    " Email: "+ this.getEmail() +
                    " Year : " + this.getYear());
   }

If you need to read all values from a section in properties file in a simple manner:

Your config.properties file layout :

[SECTION_NAME]  
key1 = value1  
key2 = value2  

You code:

   import configparser

   config = configparser.RawConfigParser()
   config.read('path_to_config.properties file')

   details_dict = dict(config.items('SECTION_NAME'))

This will give you a dictionary where keys are same as in config file and their corresponding values.

details_dict is :

{'key1':'value1', 'key2':'value2'}

Now to get key1's value : details_dict['key1']

Putting it all in a method which reads that section from config file only once(the first time the method is called during a program run).

def get_config_dict():
    if not hasattr(get_config_dict, 'config_dict'):
        get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
    return get_config_dict.config_dict

Now call the above function and get the required key's value :

config_details = get_config_dict()
key_1_value = config_details['key1'] 

-------------------------------------------------------------

Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.

def get_config_section():
    if not hasattr(get_config_section, 'section_dict'):
        get_config_section.section_dict = dict()

        for section in config.sections():
            get_config_section.section_dict[section] = 
                             dict(config.items(section))

    return get_config_section.section_dict

To access:

config_dict = get_config_section()

port = config_dict['DB']['port'] 

(here 'DB' is a section name in config file and 'port' is a key under section 'DB'.)

You might be interested in a proposal for some new operators that are similar to the conditional operator. The null-safe operators will enable code like this:

String s = mayBeNull?.toString() ?: "null";

It would be especially convenient where auto-unboxing takes place.

Integer ival = ...;  // may be null
int i = ival ?: -1;  // no NPE from unboxing

This is an older question that needs a newer answer that will address @Christopher Thomas's concern above in the accept answer's comments. If you don't navigate away from the page and then select the file a second time, you need to clear the value when you click or do a touchstart(for mobile). The below will work even when you navigate away from the page and uses jquery:

//the HTML
<input type="file" id="file" name="file" />



//the JavaScript

/*resets the value to address navigating away from the page 
and choosing to upload the same file */ 

$('#file').on('click touchstart' , function(){
    $(this).val('');
});


//Trigger now when you have selected any file 
$("#file").change(function(e) {
    //do whatever you want here
});

By using Server.Transfer("YourCurrentPage.aspx"); we can easily acheive this and it is better than Response.Redirect(); coz Server.Transfer() will save you the round trip.

You can use Web SQL API which is an ordinary SQLite database in your browser and you can open/modify it like any other SQLite databases for example with Lita.

Chrome locates databases automatically according to domain names or extension id. A few months ago I posted on my blog short article on how to delete Chrome's database because when you're testing some functionality it's quite useful.

Try like this:

$url = 'url_to_post';
// this is only part of the data you need to sen
$customer_data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
// As per your API, the customer data should be structured this way
$data = array("customer" => $customer_data);
// And then encoded as a json string
$data_string = json_encode($data);
$ch=curl_init($url);

curl_setopt_array($ch, array(
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $data_string,
    CURLOPT_HEADER => true,
    CURLOPT_HTTPHEADER => array('Content-Type:application/json', 'Content-Length: ' . strlen($data_string)))
));

$result = curl_exec($ch);
curl_close($ch);

The key thing you've forgotten was to json_encode your data. But you also may find it convenient to use curl_setopt_array to set all curl options at once by passing an array.

I prefer the capitalized .NET types (rather than the aliases) for formatting reasons. The .NET types are colored the same as other object types (the value types are proper objects, after all).

Conditional and control keywords (like if, switch, and return) are lowercase and colored dark blue (by default). And I would rather not have the disagreement in use and format.

Consider:

String someString; 
string anotherString;
