Syntax:

$data = Model::whereIn('field_name', [1, 2, 3])->get();

Use for Users Model

$usersList = Users::whereIn('id', [1, 2, 3])->get();

I solved this problem by realizing that the Target Framework for my test project was different than the project under test. Yes, I caused this problem by changing the target framework from the default (Project>Properties>Application), but failed to this this for the test project, which was created several weeks later. The mismatch did not cause a compiler error, but it did result in a warning in the Error List window. Once I selected the option to display warnings, the solution was obvious.

Marked answer work!! but Not in my case there's more then one datepicker and only want to implement on particular datepicker

So I use instance of dp and find datepicker Div and add hide class

Here's Code

<style>
    .hide-day-calender .ui-datepicker-calendar{
        display:none;
    }
</style>

<script>
        $('#dpMonthYear').datepicker({ 
            changeMonth: true,
            changeYear: true,
            showButtonPanel: true,
            dateFormat: 'MM yy',
            onClose: function (dateText, inst) { 
                $(this).datepicker('setDate', new Date(inst.selectedYear, inst.selectedMonth, 1));
            },
            beforeShow: function (elem,dp) {
                $(dp.dpDiv).addClass('hide-day-calender'); //here a change
            }
        });
</script>

Note: You can not target .ui-datepicker-calendar and set css, because it will constantly rendering while selection/changes

Here, using CASE Statement and find result:

select (case when condition1 then result1
             when condition2 then result2
             else result3
             end) as columnname from tablenmae:

For example:

select (CASE WHEN IDParent< 1 then ID 
             else IDParent END) as columnname
from tablenmae

Uncaught TypeError: undefined is not a function example_app.js:7

This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined.

So what's on example_app.js line 7? Looks like this:

var tasks = new ExampleApp.Collections.Tasks(data.tasks);

There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks is undefined.

So lets look at where that is declared:

var Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks. But you never add it to the ExampleApp.Collections object, a place you later expect it to be.

Change that to this, and I bet you'd be good.

ExampleApp.Collections.Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.

In Javascript, when you execute a function, it's evaluated like:

expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does

That expression can be complex. So when you see undefined is not a function it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.

And in this case, it was because you didn't put something where you thought you did.

using jquery $.each you can access all data and also set in table like this

<table style="width: 100%">
     <thead>
          <tr>
               <th>Id</th>
               <th>Name</th>
               <th>Category</th>
               <th>Color</th>
           </tr>
     </thead>
     <tbody id="tbody">
     </tbody>
</table>

$.each(data, function (index, item) {
     var eachrow = "<tr>"
                 + "<td>" + item[1] + "</td>"
                 + "<td>" + item[2] + "</td>"
                 + "<td>" + item[3] + "</td>"
                 + "<td>" + item[4] + "</td>"
                 + "</tr>";
     $('#tbody').append(eachrow);
});

In order to get proper responses back from async methods, you need to put await while calling those task methods. That will wait for converting it back to the returned value type rather task type.

E.g var content = await StringAsyncTask (

where public async Task<String> StringAsyncTask ())

It's easy,this is my solution using objects!

My POJO

public class Person implements Serializable{

    private String name;
    private int age;

    //get & set

}

Method Notification

  Person person = new Person();
  person.setName("david hackro");
  person.setAge(10);

    Intent notificationIntent = new Intent(this, Person.class);
    notificationIntent.putExtra("person",person);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.notification_icon)
                .setAutoCancel(true)
                .setColor(getResources().getColor(R.color.ColorTipografiaAdeudos))
                .setPriority(2)
                .setLargeIcon(bm)
                .setTicker(fotomulta.getTitle())
                .setContentText(fotomulta.getMessage())
                .setContentIntent(PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT))
                .setWhen(System.currentTimeMillis())
                .setContentTitle(fotomulta.getTicketText())
                .setDefaults(Notification.DEFAULT_ALL);

New Activity

 private Person person;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_notification_push);
    person = (Person) getIntent().getSerializableExtra("person");
}

Good Luck!!

Yes, you can do almost that:

SELECT dbo.GetBusinessDays(a.opendate,a.closedate) as BusinessDays
FROM account a
WHERE...

MERGE INTO OPT
USING
    (SELECT 1 "one" FROM dual) 
ON
    (OPT.email= '[email protected]' and OPT.campaign_id= 100) 
WHEN NOT matched THEN
INSERT (email, campaign_id)
VALUES ('[email protected]',100) 
;

Here's one that works for floats too:

def float2comma(f):
    s = str(abs(f)) # Convert to a string
    decimalposition = s.find(".") # Look for decimal point
    if decimalposition == -1:
        decimalposition = len(s) # If no decimal, then just work from the end
    out = "" 
    for i in range(decimalposition+1, len(s)): # do the decimal
        if not (i-decimalposition-1) % 3 and i-decimalposition-1: out = out+","
        out = out+s[i]      
    if len(out):
        out = "."+out # add the decimal point if necessary
    for i in range(decimalposition-1,-1,-1): # working backwards from decimal point
        if not (decimalposition-i-1) % 3 and decimalposition-i-1: out = ","+out
        out = s[i]+out      
    if f < 0:
        out = "-"+out
    return out

Usage Example:

>>> float2comma(10000.1111)
'10,000.111,1'
>>> float2comma(656565.122)
'656,565.122'
>>> float2comma(-656565.122)
'-656,565.122'

Weirdly I can answer but not comment... I liked Multitaskpro's approach of shifting everything to make the centre of the circle fall on the origin. Unfortunately there are two problems in his code. First in the under-the-square-root part you need to remove the double power. So not:

var underRadical = Math.pow((Math.pow(r,2)*(Math.pow(m,2)+1)),2)-Math.pow(b,2));

but:

var underRadical = Math.pow(r,2)*(Math.pow(m,2)+1)) - Math.pow(b,2);

In the final coordinates he forgets to shift the solution back. So not:

var i1 = {x:t1,y:m*t1+b}

but:

var i1 = {x:t1+c.x, y:m*t1+b+c.y};

The whole function then becomes:

function interceptOnCircle(p1, p2, c, r) {
    //p1 is the first line point
    //p2 is the second line point
    //c is the circle's center
    //r is the circle's radius

    var p3 = {x:p1.x - c.x, y:p1.y - c.y}; //shifted line points
    var p4 = {x:p2.x - c.x, y:p2.y - c.y};

    var m = (p4.y - p3.y) / (p4.x - p3.x); //slope of the line
    var b = p3.y - m * p3.x; //y-intercept of line

    var underRadical = Math.pow(r,2)*Math.pow(m,2) + Math.pow(r,2) - Math.pow(b,2); //the value under the square root sign 

    if (underRadical < 0) {
        //line completely missed
        return false;
    } else {
        var t1 = (-m*b + Math.sqrt(underRadical))/(Math.pow(m,2) + 1); //one of the intercept x's
        var t2 = (-m*b - Math.sqrt(underRadical))/(Math.pow(m,2) + 1); //other intercept's x
        var i1 = {x:t1+c.x, y:m*t1+b+c.y}; //intercept point 1
        var i2 = {x:t2+c.x, y:m*t2+b+c.y}; //intercept point 2
        return [i1, i2];
    }
}

Open up your DevTools and press F1 to access the settings. Look for the console section and check the checkbox for "Log XMLHttpRequests".

Now all of your ajax and other similar requests will be logged in the console.

I prefer this method because it usually allows me to see everything that I'm looking for in the console without having to go to the network tab.

You might also consider Microsoft Enterprise Library Logging Block. It comes with nice designer.

After adding the ICO file to your apps resources, you can use references it using My.Resources.YourIconNameWithoutExtension

For example if I had a file called Logo-square.ico added to my apps resources, I can set it to an icon with:

NotifyIcon1.Icon = My.Resources.Logo_square

You need to add a reference to the .NET assembly System.Data.Linq

By default, unlike an exception, a warning doesn't interrupt.

After import warnings, it is possible to specify a Warnings class when generating a warning. If one is not specified, it is literally UserWarning by default.

>>> warnings.warn('This is a default warning.')
<string>:1: UserWarning: This is a default warning.

To simply use a preexisting class instead, e.g. DeprecationWarning:

>>> warnings.warn('This is a particular warning.', DeprecationWarning)
<string>:1: DeprecationWarning: This is a particular warning.

Creating a custom warning class is similar to creating a custom exception class:

>>> class MyCustomWarning(UserWarning):
...     pass
... 
... warnings.warn('This is my custom warning.', MyCustomWarning)

<string>:1: MyCustomWarning: This is my custom warning.

For testing, consider assertWarns or assertWarnsRegex.

As an alternative, especially for standalone applications, consider the logging module. It can log messages having a level of debug, info, warning, error, etc. Log messages having a level of warning or higher are by default printed to stderr.

The question is really about scope, as the other guy put it.

In short, consider this "module":

Public Var1 As variant     'Var1 can be used in all
                           'modules, class modules and userforms of 
                           'thisworkbook and will preserve any values
                           'assigned to it until either the workbook
                           'is closed or the project is reset.

Dim Var2 As Variant        'Var2 and Var3 can be used anywhere on the
Private Var3 As Variant    ''current module and will preserve any values
                           ''they're assigned until either the workbook
                           ''is closed or the project is reset.

Sub MySub()                'Var4 can only be used within the procedure MySub
    Dim Var4 as Variant    ''and will only store values until the procedure 
End Sub                    ''ends.

Sub MyOtherSub()           'You can even declare another Var4 within a
    Dim Var4 as Variant    ''different procedure without generating an
End Sub                    ''error (only possible confusion). 

You can check out this MSDN reference for more on variable declaration and this other Stack Overflow Question for more on how variables go out of scope.

Two other quick things:

1. Be organized when using workbook level variables, so your code doesn't get confusing. Prefer Functions (with proper data types) or passing arguments ByRef.
2. If you want a variable to preserve its value between calls, you can use the Static statement.

The bundle identifier is an ID for your application used by the system as a domain for which it can store settings and reference your application uniquely.

It is represented in reverse DNS notation and it is recommended that you use your company name and application name to create it.

An example bundle ID for an App called The Best App by a company called Awesome Apps would look like:

com.awesomeapps.thebestapp

In this case the suffix is thebestapp.

I had the same problem with fancybox and an iframe, googled for a solution and ended up here. The overflow: hidden did not work for me, however I found out that fancybox allows you to set the option for the iframe scrolling (equivalent to setting "scrolling=no" attribute on the iframe), which fixes the problem in IE7 in a more graceful manner:

$.fancybox({
    'type'        : 'iframe',
    'scrolling'   : 'no',
... and the rest of the parameters.

You could use a literal eval:

>>> ast.literal_eval('0xdeadbeef')
3735928559

Or just specify the base as argument to int:

>>> int('deadbeef', 16)
3735928559

A trick that is not well known, if you specify the base 0 to int, then Python will attempt to determine the base from the string prefix:

>>> int("0xff", 0)
255
>>> int("0o644", 0)
420
>>> int("0b100", 0)
4
>>> int("100", 0)
100

With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.

This:

    <div class="details @(Model.Details.Count > 0 ? "show" : "hide")">

will render this:

    <div class="details hide">

and is the mark-up I want.

1. Yes
2. Yes.

Either way, when the using block is exited (either by successful completion or by error) it is closed.

Although I think it would be better to organize like this because it's a lot easier to see what is going to happen, even for the new maintenance programmer who will support it later:

using (SqlConnection connection = new SqlConnection(connectionString)) 
{    
    int employeeID = findEmployeeID();    
    try    
    {
        connection.Open();
        SqlCommand command = new SqlCommand("UpdateEmployeeTable", connection);
        command.CommandType = CommandType.StoredProcedure;
        command.Parameters.Add(new SqlParameter("@EmployeeID", employeeID));
        command.CommandTimeout = 5;

        command.ExecuteNonQuery();    
    } 
    catch (Exception) 
    { 
        /*Handle error*/ 
    }
}

For await/async aiounittest there is a slightly different pattern:

https://aiounittest.readthedocs.io/en/latest/asynctestcase.html#aiounittest.AsyncTestCase

async def test_await_async_fail(self):
    with self.assertRaises(Exception) as e:
        await async_one()

I'd also like to add that if using the three.js editor don't forget to set the background colour to clear as well in the index.html.

background-color:#00000000

I would like to complement @Tony answer, since the event is not being removed after the click outside the component. Complete receipt:

• Mark your main element with #container

  @ViewChild('container') container;
  
  _dropstatus: boolean = false;
  get dropstatus() { return this._dropstatus; }
  set dropstatus(b: boolean) 
  {
      if (b) { document.addEventListener('click', this.offclickevent);}
      else { document.removeEventListener('click', this.offclickevent);}
      this._dropstatus = b;
  }
  offclickevent: any = ((evt:any) => { if (!this.container.nativeElement.contains(evt.target)) this.dropstatus= false; }).bind(this);
  

• On the clickable element, use:

  (click)="dropstatus=true"
  

Now you can control your dropdown state with the dropstatus variable, and apply proper classes with [ngClass]...

If you need a way that passes CSP check (which prohibits unsafe-inline) then you have to use nonce method to add a unique value to both the script and the CSP directive or write your values into the html and read them again.

Nonce method for express.js:

const uuidv4 = require('uuid/v4')

app.use(function (req, res, next) {
  res.locals.nonce = uuidv4()
  next()
})

app.use(csp({
  directives: {
    scriptSrc: [
      "'self'",
      (req, res) => `'nonce-${res.locals.nonce}'`  // 'nonce-614d9122-d5b0-4760-aecf-3a5d17cf0ac9'
    ]
  }
}))

app.use(function (req, res) {
  res.end(`<script nonce="${res.locals.nonce}">alert(1 + 1);</script>`)
})

or write values to html method. in this case using Jquery:

<div id="account" data-email="{{user.email}}"></div>
...


$(document).ready(() => {
    globalThis.EMAIL = $('#account').data('email');
}

This prints true (even though we don't use equals method: correct way to compare strings)

    String s = "a" + "bc";
    String t = "ab" + "c";
    System.out.println(s == t);

When compiler optimizes your string literals, it sees that both s and t have same value and thus you need only one string object. It's safe because String is immutable in Java.
As result, both s and t point to the same object and some little memory saved.

Name 'string pool' comes from the idea that all already defined string are stored in some 'pool' and before creating new String object compiler checks if such string is already defined.

It turns out that you can create 32-bit ODBC connections using C:\Windows\SysWOW64\odbcad32.exe. My solution was to create the 32-bit ODBC connection as a System DSN. This still didn't allow me to connect to it since .NET couldn't look it up. After significant and fruitless searching to find how to get the OdbcConnection class to look for the DSN in the right place, I stumbled upon a web site that suggested modifying the registry to solve a different problem.

I ended up creating the ODBC connection directly under HKLM\Software\ODBC. I looked in the SysWOW6432 key to find the parameters that were set up using the 32-bit version of the ODBC administration tool and recreated this in the standard location. I didn't add an entry for the driver, however, as that was not installed by the standard installer for the app either.

After creating the entry (by hand), I fired up my windows service and everything was happy.

First of all, there's no such thing as a JSON object. What you've got in your question is a JavaScript object literal (see here for a great discussion on the difference). Here's how you would go about serializing what you've got to JSON though:

I would use an anonymous type filled with your results type:

string json = JsonConvert.SerializeObject(new
{
    results = new List<Result>()
    {
        new Result { id = 1, value = "ABC", info = "ABC" },
        new Result { id = 2, value = "JKL", info = "JKL" }
    }
});

Also, note that the generated JSON has result items with ids of type Number instead of strings. I doubt this will be a problem, but it would be easy enough to change the type of id to string in the C#.

I'd also tweak your results type and get rid of the backing fields:

public class Result
{
    public int id { get ;set; }
    public string value { get; set; }
    public string info { get; set; }
}

Furthermore, classes conventionally are PascalCased and not camelCased.

Here's the generated JSON from the code above:

{
  "results": [
    {
      "id": 1,
      "value": "ABC",
      "info": "ABC"
    },
    {
      "id": 2,
      "value": "JKL",
      "info": "JKL"
    }
  ]
}

Here is another way to use SQL SELECT statement in VBA:

 sSQL = "SELECT Variable FROM GroupTable WHERE VariableCode = '" & Me.comboBox & "'" 
 Set rs = CurrentDb.OpenRecordset(sSQL)
 On Error GoTo resultsetError 
 dbValue = rs!Variable
 MsgBox dbValue, vbOKOnly, "RS VALUE"
resultsetError:
 MsgBox "Error Retrieving value from database",VbOkOnly,"Database Error"

With underscorejs

_.uniq([1, 2, 1, 3, 1, 4]); //=> [1, 2, 3, 4]

If installing on Ubuntu using apt-get, try /usr/share/nginx/www.

EDIT:

On more recent versions the path has changed to: /usr/share/nginx/html

2019 EDIT:

Might try in /var/www/html/index.nginx-debian.html too.

If you mark a form element as required="" then novalidate="" does not help.

A way to circumvent the required validation is to disable the element.

Just initialize it with empty vectors:

df <- data.frame(Date=as.Date(character()),
                 File=character(), 
                 User=character(), 
                 stringsAsFactors=FALSE) 

Here's an other example with different column types :

df <- data.frame(Doubles=double(),
                 Ints=integer(),
                 Factors=factor(),
                 Logicals=logical(),
                 Characters=character(),
                 stringsAsFactors=FALSE)

str(df)
> str(df)
'data.frame':   0 obs. of  5 variables:
 $ Doubles   : num 
 $ Ints      : int 
 $ Factors   : Factor w/ 0 levels: 
 $ Logicals  : logi 
 $ Characters: chr 

N.B. :

Initializing a data.frame with an empty column of the wrong type does not prevent further additions of rows having columns of different types.
This method is just a bit safer in the sense that you'll have the correct column types from the beginning, hence if your code relies on some column type checking, it will work even with a data.frame with zero rows.

if you using rails and have problem apply it, I would like to add some tips from original answer posted by @Fernando Kosh

• Download file zip and copy file bootstrap-filestyle.min.js ke folder app/assets/javascripts/

• open your application.js and add this line below

  //= require bootstrap-filestyle.min

• open your coffee and add this line

  $(":file").filestyle({buttonName: "btn-primary",buttonBefore: true,buttonText: " Your text here",icon: false});

I use open query to perform this task like so:

select top 1 *
INTO [DATABASE_TO_INSERT_INTO].[dbo].[TABLE_TO_SELECT_INTO]
from openquery(
    [LINKED_SERVER_NAME],
    'select * from [DATABASE_ON_LINKED_SERVER].[dbo].[TABLE_TO_SELECT_FROM]'
)

The example above uses open query to select data from a database on a linked server into a database of your choosing.

Note: For completeness of reference, you may perform a simple select like so:

select top 1 * from openquery(
    [LINKED_SERVER_NAME],
    'select * from [DATABASE_ON_LINKED_SERVER].[dbo].[TABLE_TO_SELECT_FROM]'
)

I would emphasize the importance of limiting the ::ng-deep to only children of a component by requiring the parent to be an encapsulated css class.

For this to work it's important to use the ::ng-deep after the parent, not before otherwise it would apply to all the classes with the same name the moment the component is loaded.

Using the :host keyword before ::ng-deep will handle this automatically:

:host ::ng-deep .mat-checkbox-layout

Alternatively you can achieve the same behavior by adding a component scoped CSS class before the ::ng-deep keyword:

.my-component ::ng-deep .mat-checkbox-layout {
    background-color: aqua;
}

Component template:

<h1 class="my-component">
    <mat-checkbox ....></mat-checkbox>
</h1>

Resulting (Angular generated) css will then include the uniquely generated name and apply only to its own component instance:

.my-component[_ngcontent-c1] .mat-checkbox-layout {
    background-color: aqua;
}

Or you could simply use

View.isShown()

While I agree with CMS about doing this in an unobtrusive manner (via a lib like jquery or dojo), here's what also work:

<script type="text/javascript">
function parse(a, b, c) {
    alert(c);
  }

</script>

<a href="#x" onclick="parse('#', false, 'xyc&quot;foo');return false;">Test</a>

The reason it barfs is not because of JavaScript, it's because of the HTML parser. It has no concept of escaped quotes to it trundles along looking for the end quote and finds it and returns that as the onclick function. This is invalid javascript though so you don't find about the error until JavaScript tries to execute the function..

You can use the tool APIC available here https://chrome.google.com/webstore/detail/apic-complete-api-solutio/ggnhohnkfcpcanfekomdkjffnfcjnjam. This tool allows you to test websocket which use either StompJS or native Websocket. More info here at www.apic.app

Have a look at this picture: Graphical Projections

The glOrtho command produces an "Oblique" projection that you see in the bottom row. No matter how far away vertexes are in the z direction, they will not recede into the distance.

I use glOrtho every time I need to do 2D graphics in OpenGL (such as health bars, menus etc) using the following code every time the window is resized:

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, windowWidth, windowHeight, 0.0f, 0.0f, 1.0f);

This will remap the OpenGL coordinates into the equivalent pixel values (X going from 0 to windowWidth and Y going from 0 to windowHeight). Note that I've flipped the Y values because OpenGL coordinates start from the bottom left corner of the window. So by flipping, I get a more conventional (0,0) starting at the top left corner of the window rather.

Note that the Z values are clipped from 0 to 1. So be careful when you specify a Z value for your vertex's position, it will be clipped if it falls outside that range. Otherwise if it's inside that range, it will appear to have no effect on the position except for Z tests.

Try this. It's a modified version of the one posted by RedFilter ... this SQL removes all tags except BR, B, and P with any accompanying attributes:

CREATE FUNCTION [dbo].[StripHtml] (@HTMLText VARCHAR(MAX))
RETURNS VARCHAR(MAX)
AS
BEGIN
 DECLARE @Start  INT
 DECLARE @End    INT
 DECLARE @Length INT
 DECLARE @TempStr varchar(255)

 SET @Start = CHARINDEX('<',@HTMLText)
 SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText))
 SET @Length = (@End - @Start) + 1

 WHILE @Start > 0 AND @End > 0 AND @Length > 0
 BEGIN
   IF (UPPER(SUBSTRING(@HTMLText, @Start, 3)) <> '<BR') AND (UPPER(SUBSTRING(@HTMLText, @Start, 2)) <> '<P') AND (UPPER(SUBSTRING(@HTMLText, @Start, 2)) <> '<B') AND (UPPER(SUBSTRING(@HTMLText, @Start, 3)) <> '</B')
   BEGIN
      SET @HTMLText = STUFF(@HTMLText,@Start,@Length,'')
   END
    
   SET @Start = CHARINDEX('<',@HTMLText, @End)
   SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText, @Start))
   SET @Length = (@End - @Start) - 1
 END

 RETURN RTRIM(LTRIM(@HTMLText))
END

$(: ...) is a little less ugly, but still not good.

For ENTER key, why not use (keyup.enter):

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="values=box.value">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  values = '';
}

I think you are not asking the right question--

A string in python has no property corresponding to 'ascii', utf-8, or any other encoding. The source of your string (whether you read it from a file, input from a keyboard, etc.) may have encoded a unicode string in ascii to produce your string, but that's where you need to go for an answer.

Perhaps the question you can ask is: "Is this string the result of encoding a unicode string in ascii?" -- This you can answer by trying:

try:
    mystring.decode('ascii')
except UnicodeDecodeError:
    print "it was not a ascii-encoded unicode string"
else:
    print "It may have been an ascii-encoded unicode string"

We ran into this issue when we created the table using phppgadmin client. With phppgadmin we did not specify any double quotes in column name and still we ran into same issue.

It we create column with caMel case then phpPGAdmin implicitly adds double quotes around the column name. If you create column with all lower case then you will not run into this issue.

You can alter the column in phppgadmin and change the column name to all lower case this issue will go away.

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.

And yes you can add header something like this way:

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

Thought i should add here, that if you want to access rows or columns to loop through them, you do this:

import pandas as pd

# open the file
xlsx = pd.ExcelFile("PATH\FileName.xlsx")

# get the first sheet as an object
sheet1 = xlsx.parse(0)
    
# get the first column as a list you can loop through
# where the is 0 in the code below change to the row or column number you want    
column = sheet1.icol(0).real

# get the first row as a list you can loop through
row = sheet1.irow(0).real

Edit:

The methods icol(i) and irow(i) are deprecated now. You can use sheet1.iloc[:,i] to get the i-th col and sheet1.iloc[i,:] to get the i-th row.

write a for or while loop and put all of your code inside of it? Goto type programming is a thing of the past.

In my case I had one local commit, which wasn't pushed to origin\master, but commited to my local master branch. This local commit should be now pushed to another branch.

With Git Extensions you can do something like this:

• (Create if not existing and) checkout new branch, where you want to push your commit.
• Select the commit from the history, which should get commited & pushed to this branch.
• Right click and select Cherry pick commit.
• Press Cherry pick button afterwards.
• The selected commit get's applied to your checked out branch. Now commit and push it.
• Check out your old branch, with the faulty commit.
• Hard reset this branch to the second last commit, where everything was ok (be aware what are you doing here!). You can do that via right click on the second last commit and select Reset current branch to here. Confirm the opperation, if you know what you are doing.

You could also do that on the GIT command line. Example copied from David Christensen:

I think you'll find git cherry-pick + git reset to be a much quicker workflow:

Using your same scenario, with "feature" being the branch with the top-most commit being incorrect, it'd be much easier to do this:

git checkout master
git cherry-pick feature
git checkout feature
git reset --hard HEAD^

Saves quite a bit of work, and is the scenario that git cherry-pick was designed to handle.

I'll also note that this will work as well if it's not the topmost commit; you just need a commitish for the argument to cherry-pick, via:

git checkout master
git cherry-pick $sha1
git checkout feature
git rebase -i ... # whack the specific commit from the history

The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.

Proxy Error

The proxy server received an invalid response from an upstream server.
 The proxy server could not handle the request GET /lin/Campaignn.jsp.

As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.

For those who want to put color in String.xml directly and don't want to use color...

example

<string name="status_stop"><font fgcolor='#FF8E8E93'>Stopped</font></string> <!--gray-->
<string name="status_running"><font fgcolor='#FF4CD964'>Running</font></string> <!--green-->
<string name="status_error"><font fgcolor='#FFFF3B30'>Error</font></string> <!--red-->

as you see there is gray, red, and green, there is 8 characters, first two for transparency and other for color.

Example

This a description of color and transparency
#   FF               FF3B30    
    Opacity          Color

Note: Put color in text in the same string.xml will not work in Android 6.0 and above

Reference: Understanding colors in Android (6 characters)

Update: 10/OCT/2016

This function is compatible with all version of android, I didn't test in android 7.0. Use this function to get color and set in textview

Example format xml in file string and colors

<!-- /res/values/strings.xml -->
<string name="status_stop">Stopped</string>
<string name="status_running">Running</string>
<string name="status_error">Error</string>

<!-- /res/values/colors.xml -->
<color name="status_stop">#8E8E93</color>
<color name="status_running">#4CD964</color>
<color name="status_error">#FF3B30</color>

Function to get color from xml with validation for android 6.0 and above

public static int getColorWrapper(Context context, int id) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {//if actual version is >= 6.0
            return context.getColor(id);
        } else {
            //noinspection deprecation
            return context.getResources().getColor(id);
        }
    }

Example:

TextView status = (TextView)findViewById(R.id.tvstatus);
status.setTextColor(getColorWrapper(myactivity.this,R.color.status_stop));

Reference: getColor(int id) deprecated on Android 6.0 Marshmallow (API 23)

Since Result Set is an interface, When you obtain a reference to a ResultSet through a JDBC call, you are getting an instance of a class that implements the ResultSet interface. This class provides concrete implementations of all of the ResultSet methods.

Interfaces are used to divorce implementation from, well, interface. This allows the creation of generic algorithms and the abstraction of object creation. For example, JDBC drivers for different databases will return different ResultSet implementations, but you don't have to change your code to make it work with the different drivers

In very short, if your ResultSet contains result, then using rs.next return true if you have recordset else it returns false.

I lost several hours on this error in Azure DevOps when I set the 'Visual Studio Build' task in a build pipeline to build an individual project in my solution, rather than the whole solution.

Doing that means that DevOps either doesn't build any (or possibly some, I'm not sure which) of the projects referenced by the project you've targeted for the build, and therefore those projects won't have their project.json.asset files generated, which then causes this issue.

The solution for me was to swap from using the VS Build task to the MSBuild task. Using the MSBuild task for an individual project correctly builds any projects referenced by the project you're building and eliminates this error.

Yes, there is a static DoEvents method in the Application class in the System.Windows.Forms namespace. System.Windows.Forms.Application.DoEvents() can be used to process the messages waiting in the queue on the UI thread when performing a long-running task in the UI thread. This has the benefit of making the UI seem more responsive and not "locked up" while a long task is running. However, this is almost always NOT the best way to do things. According to Microsoft calling DoEvents "...causes the current thread to be suspended while all waiting window messages are processed." If an event is triggered there is a potential for unexpected and intermittent bugs that are difficult to track down. If you have an extensive task it is far better to do it in a separate thread. Running long tasks in a separate thread allows them to be processed without interfering with the UI continuing to run smoothly. Look here for more details.

Here is an example of how to use DoEvents; note that Microsoft also provides a caution against using it.

I suggest create a list and append dictionary into it.

x   = []
cur = db.dbname.find()
for i in cur:
    x.append(i)
print(x)

Now x is a list of dictionary, you can manipulate the same in usual python way.

It depends on what type of objects stored in the List, and whether it has implementation for toString() method. System.out.println(list) should print all the standard java object types (String, Long, Integer etc). In case, if we are using custom object types, then we need to override toString() method of our custom object.

Example:

class Employee {
 private String name;
 private long id;

 @Override
 public String toString() {
   return "name: " + this.name() + 
           ", id: " + this.id();
 }  
}

Test:

class TestPrintList {
   public static void main(String[] args) {
     Employee employee1 =new Employee("test1", 123);
     Employee employee2 =new Employee("test2", 453);
     List<Employee> employees = new ArrayList(2);
     employee.add(employee1);
     employee.add(employee2);
     System.out.println(employees);
   }
}

Option using dplyr

require(dplyr)
dt<-as.data.frame(matrix(runif(10*10),10,10))
dt <- select(dt, -V1, -V2, -V3, -V4)
cor(dt)

Even though it is about international numbers I would want the code to be like :

/^(\+|\d)[0-9]{7,16}$/;

As you can have international numbers starting with '00' as well.

Why I prefer 15 digits : http://en.wikipedia.org/wiki/E.164

Your code in the last update should not compile, much less run. You're passing &x to LoadData. &x has the type of **words, but LoadData expects words* . Of course it crashes when you call realloc on a pointer that's pointing into stack.

The way to fix it is to change LoadData to accept words** . Thi sway, you can actually modify the pointer in main(). For example, realloc call would look like

*x = (words*) realloc(*x, sizeof(words)*2);

It's the same principlae as in "num" being int* rather than int.

Besides this, you need to really figure out how the strings in words ere stored. Assigning a const string to char * (as in str2 = "marley\0") is permitted, but it's rarely the right solution, even in C.

Another point: non need to have "marley\0" unless you really need two 0s at the end of string. Compiler adds 0 tho the end of every string literal.

Current best practice (tidyverse) is:

require(dplyr)
df1 %>% count(Year, Month)

You can map a key in Eclipse to manually remove trailing whitespaces in the whole file, but only on request instead of automatically at save. (Preference/Keys and then map a set of keys to File/Remove Trailing Whitespace) This can be useful if you want to sanitize all new files, but keep legacy code untouched.

Another strategy is to activate visual display of whitespace, so at least you'll know when you're adding some trailing whitespace. As far as I know, there's no way to display only trailing whitespace though, but I'll be glad to be proved wrong.

I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

I know it's 5 years late, if you want to use nodemon.json you may try this,

{
  "verbose": true,
  "ignore": ["*.test.js", "fixtures/*"],
  "execMap": {
    "js": "electron ." // 'js' is for the extension, and 'electron .' is command that I want to execute
  }
}

The execMap will execute like a script in package.json, then you can run nodemon js

Maybe this would work:

Remove the double backslashes from the parameter of the split method:

split = docStr.split("\n");

I was able to call my callback function at minimum of 250ms using audio tag and handling its ontimeupdate event. Its called 3-4 times in a second. Its better than one second lagging setTimeout

$("#chkdwn2").change(function() { 
    if (this.checked) $("#dropdown").prop("disabled",'disabled');
}) 

I use this form for just this sort of thing:

gci . hosts -r | ? {!$_.PSIsContainer}

. maps to positional parameter Path and "hosts" maps to positional parameter Filter. I highly recommend using Filter over Include if the provider supports filtering (and the filesystem provider does). It is a good bit faster than Include.

If you are using Ant and trying to build then you need to :

1. Specify tomcat location by <property name="tomcat-home" value="C:\xampp\tomcat" />

2. Add tomcat libs to your already defined path for jars by

   <path id="libs"> <fileset includes="*.jar" dir="${WEB-INF}/lib" /> <fileset includes="*.jar" dir="${tomcat-home}/bin" /> <fileset includes="*.jar" dir="${tomcat-home}/lib" /> </path>

Based on your newly-added backstory with the question, why not just return an integer from 1 to 12 for the month, and let the main() function use a switch statement or if-else ladder to decide what to print? It's certainly not the best way to go - char* would be - but in the context of a class like this I imagine it's probably the most elegant.

Actually, you CAN get the whole Bitcoin trades history from Bitcoincharts in CSV format here : http://api.bitcoincharts.com/v1/csv/

it is updated twice a day for active exchanges, and there is a few dead exchanges, too.

EDIT: Since there are no column headers in the CSVs, here's what they are : column 1) the trade's timestamp, column 2) the price, column 3) the volume of the trade

To get the last record details, use the code below:

Model::where('field', 'value')->get()->last()

You can call multiple functions with ';'

ng-click="edit($index); open()"

The tensorflow version can be checked either on terminal or console or in any IDE editer as well (like Spyder or Jupyter notebook, etc)

Simple command to check version:

(py36) C:\WINDOWS\system32>python
Python 3.6.8 |Anaconda custom (64-bit)

>>> import tensorflow as tf
>>> tf.__version__
'1.13.1'

I am guessing there is a fundamental reason for the change, it isn't merely cosmetic to make the old interpretation clearer: that reason is concurrency. Unspecified order of elaboration is merely selection of one of several possible serial orderings, this is quite different to before and after orderings, because if there is no specified ordering, concurrent evaluation is possible: not so with the old rules. For example in:

f (a,b)

previously either a then b, or, b then a. Now, a and b can be evaluated with instructions interleaved or even on different cores.

The IIS7 module will let you redirect.

                <conditions>
                    <add input="{HTTPS}" pattern="^OFF$"/>
                </conditions>
                <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="SeeOther"/>
            </rule>

you just make a list of lists like so:

results.Add(new List<string>()); //adds a new list to your list of lists
results[0].Add("this is a string"); //adds a string to the first list
results[0][0]; //gets the first string in your first list

Using the stat to figure out the last modification date of the file, date to figure out the current time and a liberal use of bashisms, one can do the test that you want based on the file's last modification time¹.

if [ "$(( $(date +"%s") - $(stat -c "%Y" $somefile) ))" -gt "7200" ]; then
   echo "$somefile is older then 2 hours"
fi

While the code is a bit less readable then the find approach, I think its a better approach then running find to look at a file you already "found". Also, date manipulation is fun ;-)

1. As Phil correctly noted creation time is not recorded, but use %Z instead of %Y below to get "change time" which may be what you want.

[Update]

For mac users, use stat -f "%m" $somefile instead of the Linux specific syntax above

By using drop_duplicates

pd.concat([df1,df2]).drop_duplicates(keep=False)

Update :

Above method only working for those dataframes they do not have duplicate itself, For example

df1=pd.DataFrame({'A':[1,2,3,3],'B':[2,3,4,4]})
df2=pd.DataFrame({'A':[1],'B':[2]})

It will output like below , which is wrong

Wrong Output :

pd.concat([df1, df2]).drop_duplicates(keep=False)
Out[655]: 
   A  B
1  2  3

Correct Output

Out[656]: 
   A  B
1  2  3
2  3  4
3  3  4

How to achieve that?

Method 1: Using isin with tuple

df1[~df1.apply(tuple,1).isin(df2.apply(tuple,1))]
Out[657]: 
   A  B
1  2  3
2  3  4
3  3  4

Method 2: merge with indicator

df1.merge(df2,indicator = True, how='left').loc[lambda x : x['_merge']!='both']
Out[421]: 
   A  B     _merge
1  2  3  left_only
2  3  4  left_only
3  3  4  left_only

I found an easy way to do it: delete and replace

describe('Test case', () => {
  const { open } = window;

  beforeAll(() => {
    // Delete the existing
    delete window.open;
    // Replace with the custom value
    window.open = jest.fn();
    // Works for `location` too, eg:
    // window.location = { origin: 'http://localhost:3100' };
  });

  afterAll(() => {
    // Restore original
    window.open = open;
  });

  it('correct url is called', () => {
    statementService.openStatementsReport(111);
    expect(window.open).toBeCalled(); // Happy happy, joy joy
  });
});

If you are developing on localhost or a port on localhost such as localhost:8080, in addition to the steps described in the answers above, you also need to ensure that you are not passing a domain value in the Set-Cookie header.
You cannot set the domain to localhost in the Set-Cookie header - that's incorrect - just omit the domain.

See Cookies on localhost with explicit domain and Why won't asp.net create cookies in localhost?

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.

Another way that generalizes more:

df$count <- unsplit(lapply(split(df, df[c("name","type")]), nrow), df[c("name","type")])

See in your library projects make the compileSdkVersion and targetSdkVersion version to same level as your application is

android {
    compileSdkVersion 28

    defaultConfig {
        consumerProguardFiles 'proguard-rules.txt'
        minSdkVersion 14
        targetSdkVersion 28
    }
}

also make all dependencies to same level

BaseAdapter is best custom adapter for listview.

Class MyAdapter extends BaseAdapter{}

and it has many functions such as getCount(), getView() etc.

the simplest way what I found from a tutorial of "TraversyMedia" is that just use https://cors-anywhere.herokuapp.com in 'axios' or 'fetch' api

https://cors-anywhere.herokuapp.com/{type_your_url_here} 

e.g.

axios.get(`https://cors-anywhere.herokuapp.com/https://www.api.com/`)

and in your case edit url as

url: 'https://cors-anywhere.herokuapp.com/https://www.api.com',

Adding another point of view to above mentioned solutions.

Implicit Wait: When created, is alive until the WebDriver object dies. And is like common for all operations.

Whereas,
Explicit wait, can be declared for a particular operation depending upon the webElement behavior. It has the benefit of customizing the polling time and satisfaction of the condition.
For example, we declared implicit Wait of 10 secs but an element takes more than that, say 20 seconds and sometimes may appears on 5 secs, so in this scenario, Explicit wait is declared.

', '.join(set_3)

The join is a string method, not a set method.

I had the same problem with an Ubuntu Linux server running subversion when accessed via Eclipse.

It has shown that the problem had to do with a warning when Apache (re)started:

[Mon Jun 30 22:27:10 2014] [warn] NameVirtualHost *:80 has no VirtualHosts

... waiting [Mon Jun 30 22:27:11 2014] [warn] NameVirtualHost *:80 has no VirtualHosts

This has been due to a new entry in ports.conf, where another NameVirtualHost directive was entered alongside the directive in sites-enabled/000-default.

After removing the directive in ports.conf, the problem had vanished (after restarting Apache, naturally)

Just do simple things to import the .py file from a different folder.

Let's say you have a directory like:

lib/abc.py

Then just keep an empty file in lib folder as named

__init__.py

And then use

from lib.abc import <Your Module name>

Keep the __init__.py file in every folder of the hierarchy of the import module.

If you do so, and you're using fail2ban, you will need to enable the proper filters/actions:

Put the following lines in /etc/fail2ban/jail.d/sshd.local

[ssh-iptables]
enabled  = true
filter   = sshd
action   = iptables[name=SSH, port=ssh, protocol=tcp]
logpath  = /var/log/secure
maxretry = 5
bantime = 86400

Enable and start fail2ban:

systemctl enable fail2ban
systemctl start fail2ban

Swift3 - In a UITextView or UILabel extension, add this function:

I added some code to keep the current attributed text if you are already using attributed strings with the view (instead of overwriting them).

func setLineHeight(_ lineHeight: CGFloat) {
    guard let text = self.text, let font = self.font else { return }

    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineSpacing = 1.0
    paragraphStyle.lineHeightMultiple = lineHeight
    paragraphStyle.alignment = self.textAlignment

    var attrString:NSMutableAttributedString
    if let attributed = self.attributedText {
        attrString = NSMutableAttributedString(attributedString: attributed)
    } else {
        attrString = NSMutableAttributedString(string: text)
        attrString.addAttribute(NSFontAttributeName, value: font, range: NSMakeRange(0, attrString.length))
    }
    attrString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSMakeRange(0, attrString.length))
    self.attributedText = attrString
}

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

• git-restore Documentation

Note that you can only read a stream once, so in some cases, you may need to clone the response in order to repeatedly read it:

fetch('example.json')
  .then(res=>res.clone().json())
  .then( json => console.log(json))

fetch('url_that_returns_text')
  .then(res=>res.clone().text())
  .then( text => console.log(text))

This will strip all commas from the text and left justify it.

for row in inputfile:
    place = row['your_row_number_here'].strip(', ')

Yes, this an older question but this may be helping all the users having problems with reCaptcha on localhost. Google indeed says "By default, all keys work on 'localhost' (or '127.0.0.1')" but for real using reCaptcha on localhost may cause problems. In my case I solved mine using secure token

I posted a WORKING SOLUTION for PHP here

I found that in my code when I used a ration or percentage for line-height line-height;1.5;

My page would scale in such a way that lower case font and upper case font would take up different page heights (I.E. All caps took more room than all lower). Normally I think this looks better, but I had to go to a fixed height line-height:24px; so that I could predict exactly how many pixels each page would take with a given number of lines.

You could just set the width to auto. Then the width of the div will equal 0 if it has no content.

width:auto;

Scenario: MongoDB(version v4.0.9).

1. Set custom folder(with name: myCustomDatabases), where to store databases.
2. In custom folder(with name: myCustomDatabases), have to create database (with name: newDb).

Resolve:

1. Create custom folder(with name: myCustomDatabases):

   D:>md myCustomDatabases
   

2. Run 'mongod --dbpath' with path to custom folder(with name: myCustomDatabases):

   mongod --dbpath "D:\myCustomDatabases"
   

3. From another 'cmd' run 'mongo':

   D:>mongo
   

   3.1. Show all databases, stored in custom folder(with name: myCustomDatabases):

   >show dbs
   admin   0.000GB
   config  0.000GB
   local   0.000GB
   

   3.2. Use database with name newDb:

   > use newDb
   switched to db newDb
   

   3.3. Show all databases, stored in custom folder(with name: myCustomDatabases):

   >show dbs
   admin   0.000GB
   config  0.000GB
   local   0.000GB
   

   !!! Noticed, that newDb is NOT in the list !!!

   3.4. Have to create a collection with a document, which will create the database newDb.

   > db.Cats.insert({name: 'Leo'})
   WriteResult({ "nInserted" : 1 })
   

   The insert({name: 'Leo'}) operation creates: the database newDB and the collection Cats, because they do not exist.

   3.5. Now the new created database newDb will be displayed in the list.

   > show dbs
   admin   0.000GB
   config  0.000GB
   local   0.000GB
   newDb   0.000GB
   

   3.6. Now in custom folder D:\myCustomDatabases, have database newDb.

If it is giving you relay access denied when you are trying to send an email from outside your network to a domain that your server is not authoritative for then it means your receive connector does not grant you the permissions for sending/relaying. Most likely what you need to do is to authenticate to the server to be granted the permissions for relaying but that does depend upon the configuration of your receive connector. In Exchange 2007/2010/2013 you would need to enable ExchangeUsers permission group as well as an authentication mechanism such as Basic authentication.

Once you're sure your receive connector is configured make sure your email client is configured for authentication as well for the SMTP server. It depends upon your server setup but normally for Exchange you would configure the username by itself, no need for the domain to appended or prefixed to it.

To test things out with authentication via telnet you can go over my post here for directions: https://jefferyland.wordpress.com/2013/05/28/essential-exchange-troubleshooting-send-email-via-telnet/

The difference between a tuple and a class is that a tuple has no property names. This is almost never a good thing, and I would only use a tuple when the arguments are fairly meaningless like in an abstract math formula Eg. abstract calculus over 5,6,7 dimensions might take a tuple for the coordinates.

print("{latitude} {longitude}".format(**geopoint))

i had the same issue and the problem was that i was missing a slash in my path.

i had

and to fix it i only needed to add the slash in between jquery-ui and jquery-ui.min:

  <script type="text/javascript" src="js/jquery-ui/jquery-ui.min.js"></script>

hope this helps :D

$.getJSON is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.

Alternatively you could use jQuery's $.when/.then(), similar to this:

var input = "netuetamundis";  var sID;  $(document).ready(function () {     $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () {         obj = name;         sID = obj.id;         console.log(sID);     })).then(function () {         $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) {             console.log(stats);         });     }); }); 

This would be more open for future modification and separates out the responsibility for the first call to know about the second call.

The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.

This is what Google has used in some of its applications for a long time now. See in the code that, if you apply next classes, they somehow hide the scrollbar in Chrome, but it still works.

The classes are jfk-scrollbar, jfk-scrollbar-borderless, and jfk-scrollbar-dark

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

I am currently working on phpDataMapper, which is an ORM designed to have simple syntax like Ruby's Datamapper project. It's still in early development as well, but it works great.

You can also specify noHistory = "true" in the tag for first activity or finish the first activity as soon as you start the second one(as David said).

AFAIK, "force close" kills the process which hosts the JVM in which your application runs and System.exit() terminates the JVM running your application instance. Both are form of abrupt terminations and not advisable for normal application flow.

Just as catching exceptions to cover logic flows that a program might undertake, is not advisable.

Your first block of code tells CLR to create a Thread (say. T) for you which is can be run as background (use thread pool threads when scheduling T ). In concise, you explicitly ask CLR to create a thread for you to do something and call Start() method on thread to start.

Your second block of code does the same but delegate (implicitly handover) the responsibility of creating thread (background- which again run in thread pool) and the starting thread through StartNew method in the Task Factory implementation.

This is a quick difference between given code blocks. Having said that, there are few detailed difference which you can google or see other answers from my fellow contributors.

You can do the following:

Python 2.x

import hashlib
print hashlib.md5("whatever your string is").hexdigest()

Python 3.x

import hashlib
print(hashlib.md5("whatever your string is".encode('utf-8')).hexdigest())

However in this case you're probably better off using this helpful Python module for interacting with the Flickr API:

UPDATED

I've updated your demo: http://jsfiddle.net/terryyounghk/QS56z/18/

Also, I've changed two ^= to *=. See http://api.jquery.com/category/selectors/

And note the :checked selector. See http://api.jquery.com/checked-selector/

function createcodes() {

    //run through each row
    $('.authors-list tr').each(function (i, row) {

        // reference all the stuff you need first
        var $row = $(row),
            $family = $row.find('input[name*="family"]'),
            $grade = $row.find('input[name*="grade"]'),
            $checkedBoxes = $row.find('input:checked');

        $checkedBoxes.each(function (i, checkbox) {
            // assuming you layout the elements this way, 
            // we'll take advantage of .next()
            var $checkbox = $(checkbox),
                $line = $checkbox.next(),
                $size = $line.next();

            $line.val(
                $family.val() + ' ' + $size.val() + ', ' + $grade.val()
            );

        });

    });
}

This explains the whole thing:

The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.

The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.

The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.

As far as I remember, this is controlled by browser settings. In other words: user can chose whether they would like to open new tab in the background or foreground. Also they can chose whether new popup should open in new tab or just... popup.

There is this extensions that adds an event listener to attribute changes.

Bind attrchange handler function to selected elements

$(selector).attrchange({
    trackValues: true, /* Default to false, if set to true the event object is 
                updated with old and new value.*/
    callback: function (event) { 
        //event               - event object
        //event.attributeName - Name of the attribute modified
        //event.oldValue      - Previous value of the modified attribute
        //event.newValue      - New value of the modified attribute
        //Triggered when the selected elements attribute is added/updated/removed
    }        
});

For me, an issue where json_encode would return null encoding of an entity was because my jsonSerialize implementation fetched entire objects for related entities; I solved the issue by making sure that I fetched the ID of the related/associated entity and called ->toArray() when there were more than one entity associated with the object to be json serialized. Note, I'm speaking about cases where one implements JsonSerializable on entities.

In the direction of Bradgonesurfing's answer, many times one doesn't really need to concatenate two vectors (O(n)), but instead just work with them as if they were concatenated (O(1)). If this is your case, it can be done without the need of Boost libraries.

The trick is to create a vector proxy: a wrapper class which manipulates references to both vectors, externally seen as a single, contiguous one.

USAGE

std::vector<int> A{ 1, 2, 3, 4, 5};
std::vector<int> B{ 10, 20, 30 };

VecProxy<int> AB(A, B);  // ----> O(1). No copies performed.

for (size_t i = 0; i < AB.size(); ++i)
    std::cout << AB[i] << " ";  // 1 2 3 4 5 10 20 30

IMPLEMENTATION

template <class T>
class VecProxy {
private:
    std::vector<T>& v1, v2;
public:
    VecProxy(std::vector<T>& ref1, std::vector<T>& ref2) : v1(ref1), v2(ref2) {}
    const T& operator[](const size_t& i) const;
    const size_t size() const;
};

template <class T>
const T& VecProxy<T>::operator[](const size_t& i) const{
    return (i < v1.size()) ? v1[i] : v2[i - v1.size()];
};

template <class T>
const size_t VecProxy<T>::size() const { return v1.size() + v2.size(); };

MAIN BENEFIT

It's O(1) (constant time) to create it, and with minimal extra memory allocation.

SOME STUFF TO CONSIDER

• You should only go for it if you really know what you're doing when dealing with references. This solution is intended for the specific purpose of the question made, for which it works pretty well. To employ it in any other context may lead to unexpected behavior if you are not sure on how references work.
• In this example, AB does not provide a non-const access operator ([ ]). Feel free to include it, but keep in mind: since AB contains references, to assign it values will also affect the original elements within A and/or B. Whether or not this is a desirable feature, it's an application-specific question one should carefully consider.
• Any changes directly made to either A or B (like assigning values, sorting, etc.) will also "modify" AB. This is not necessarily bad (actually, it can be very handy: AB does never need to be explicitly updated to keep itself synchronized to both A and B), but it's certainly a behavior one must be aware of. Important exception: to resize A and/or B to sth bigger may lead these to be reallocated in memory (for the need of contiguous space), and this would in turn invalidate AB.
• Because every access to an element is preceded by a test (namely, "i < v1.size()"), VecProxy access time, although constant, is also a bit slower than that of vectors.
• This approach can be generalized to n vectors. I haven't tried, but it shouldn't be a big deal.

The most straightforward is to simply loop through the characters in the string:

Public Function CountCharacter(ByVal value As String, ByVal ch As Char) As Integer
  Dim cnt As Integer = 0
  For Each c As Char In value
    If c = ch Then 
      cnt += 1
    End If
  Next
  Return cnt
End Function

Usage:

count = CountCharacter(str, "e"C)

Another approach that is almost as effective and gives shorter code is to use LINQ extension methods:

Public Function CountCharacter(ByVal value As String, ByVal ch As Char) As Integer
  Return value.Count(Function(c As Char) c = ch)
End Function

user double quote to get the exact value. like this:

echo "${var}"

and it will read your value correctly.

You need a spring-security-config.jar on your classpath.

The exception means that the security: xml namescape cannot be handled by spring "parsers". They are implementations of the NamespaceHandler interface, so you need a handler that knows how to process <security: tags. That's the SecurityNamespaceHandler located in spring-security-config

To find the sessions, as a DBA use

select sid,serial# from v$session where username = '<your_schema>'

If you want to be sure only to get the sessions that use SQL Developer, you can add and program = 'SQL Developer'. If you only want to kill sessions belonging to a specific developer, you can add a restriction on os_user

Then kill them with

alter system kill session '<sid>,<serial#>'

(e.g. alter system kill session '39,1232')

A query that produces ready-built kill-statements could be

select 'alter system kill session ''' || sid || ',' || serial# || ''';' from v$session where username = '<your_schema>'

This will return one kill statement per session for that user - something like:

alter system kill session '375,64855';

alter system kill session '346,53146';

    for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
        set "line=%%i"
        setlocal enabledelayedexpansion
        >>"%textFile%" echo(!line:%search%=%replace%!
        endlocal
    )

for /f will read all the data (generated by the type comamnd) before starting to process it. In the subprocess started to execute the type, we include a redirection overwritting the file (so it is emptied). Once the do clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.

Its another way to declare the constructor. You can also use the class name, for ex:

class Cat
{
    function Cat()
    {
        echo 'meow';
    }
}

and

class Cat
{
    function __construct()
    {
        echo 'meow';
    }
}

Are equivalent. They are called whenever a new instance of the class is created, in this case, they will be called with this line:

$cat = new Cat();

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

*(myString.end() - 1) maybe? That's not exactly elegant either.

A python-esque myString.at(-1) would be asking too much of an already-bloated class.

In my understanding, Get-Content eliminates ALL newlines/carriage returns when it rolls your text file through the pipeline. To do multiline regexes, you have to re-combine your string array into one giant string. I do something like:

$text = [string]::Join("`n", (Get-Content test.txt))
[regex]::Replace($text, "t`n", "ting`na ", "Singleline")

Clarification: small files only folks! Please don't try this on your 40 GB log file :)

Here is the an other way. if you don't like exceptions.

def strnumber = "100"
def intValue = strnumber.isInteger() ?  (strnumber as int) : null

Regarding tables names, case, etc, the prevalent convention is:

• SQL keywords: UPPER CASE
• names (identifiers): lower_case_with_underscores

For example:

UPDATE my_table SET name = 5;

This is not written in stone, but the bit about identifiers in lower case is highly recommended, IMO. Postgresql treats identifiers case insensitively when not quoted (it actually folds them to lowercase internally), and case sensitively when quoted; many people are not aware of this idiosyncrasy. Using always lowercase you are safe. Anyway, it's acceptable to use camelCase or PascalCase (or UPPER_CASE), as long as you are consistent: either quote identifiers always or never (and this includes the schema creation!).

I am not aware of many more conventions or style guides. Surrogate keys are normally made from a sequence (usually with the serial macro), it would be convenient to stick to that naming for those sequences if you create them by hand (tablename_colname_seq).

See also some discussion here, here and (for general SQL) here, all with several related links.

Note: Postgresql 10 introduced identity columns as an SQL-compliant replacement for serial.

        break;
    case DialogResult.No:    // No button pressed
        MessageBox.Show("You pressed No!");
        break;
    default:                 // Neither Yes nor No pressed (just in case)
        MessageBox.Show("What did you press?");
        break;
    }
}

EDIT: I haven't tried this, so I can't vouch for it! And you already know you shouldn't be doing this, so please don't do it. BUT...

Try looking here: http://sqlblog.com/blogs/denis_gobo/archive/2008/05/08/6703.aspx

The key bit is this bit which I have attempted to tweak for your purposes:

DECLARE @SQL varchar(500)

SELECT @SQL = 'osql -S' +@@servername +' -E -q "exec dbName..sprocName "'

EXEC master..xp_cmdshell @SQL

I answered a similar question a while ago. Basically, the best way would be to use the class HttpValueCollection, which ASP.NET's Request.QueryString property actually is, unfortunately it is internal in the .NET framework. You could use Reflector to grab it (and place it into your Utils class). This way you could manipulate the query string like a NameValueCollection, but with all the url encoding/decoding issues taken care for you.

HttpValueCollection extends NameValueCollection, and has a constructor that takes an encoded query string (ampersands and question marks included), and it overrides a ToString() method to later rebuild the query string from the underlying collection.

Example:

  var coll = new HttpValueCollection();

  coll["userId"] = "50";
  coll["paramA"] = "A";
  coll["paramB"] = "B";      

  string query = coll.ToString(true); // true means use urlencode

  Console.WriteLine(query); // prints: userId=50&paramA=A&paramB=B

getting following error

It happens:  Error: 
      ngModel cannot be used to register form controls with a parent formGroup directive.  Try using
      formGroup's partner directive "formControlName" instead.  Example:

Simple and clean :)

UserController.php

public function create() {
    $user = new User();

    return View::make('user.edit', compact('user'));
}

public function edit($id) {
    $user = User::find($id);

    return View::make('user.edit', compact('user'));
}

edit.blade.php

{{ Form::model($user, ['url' => ['/user', $user->id]]) }}
   {{ Form::text('name') }}
   <button>save</button>
{{ Form::close() }}

There are three unique situations:

• 4 numbers, e.g. Margin="a,b,c,d".
• 2 numbers, e.g. Margin="a,b".
• 1 number, e.g. Margin="a".

4 Numbers

If there are 4 numbers, then its left, top, right, bottom (a clockwise circle starting from the middle left margin). First number is always the "West" like "WPF":

<object Margin="left,top,right,bottom"/>

Example: if we use Margin="10,20,30,40" it generates:

2 Numbers

If there are 2 numbers, then the first is left & right margin thickness, the second is top & bottom margin thickness. First number is always the "West" like "WPF":

<object Margin="a,b"/> // Equivalent to Margin="a,b,a,b".

Example: if we use Margin="10,30", the left & right margin are both 10, and the top & bottom are both 30.

1 Number

If there is 1 number, then the number is repeated (its essentially a border thickness).

<object Margin="a"/> // Equivalent to Margin="a,a,a,a".

Example: if we use Margin="20" it generates:

Update 2020-05-27

Have been working on a large-scale WPF application for the past 5 years with over 100 screens. Part of a team of 5 WPF/C#/Java devs. We eventually settled on either using 1 number (for border thickness) or 4 numbers. We never use 2. It is consistent, and seems to be a good way to reduce cognitive load when developing.

The rule:

All width numbers start on the left (the "West" like "WPF") and go clockwise (if two numbers, only go clockwise twice, then mirror the rest).

The following (C#) code should do the trick

Uri uri = new Uri("http://www.mywebsite.com:80/pages/page1.aspx");
string requested = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port;

With native JavaScript:

newelement = element.cloneNode(bool)

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

Here is the complete documentation on MDN.

Great technical answers in the post! I have nothing technically to add to that.

One of the main reasons why new features appear in languages and software in general is marketing or company politics! :-) This must not be under estimated!

I think this applies to certain extend to delegates and events too! i find them useful and add value to the C# language, but on the other hand the Java language decided not to use them! they decided that whatever you are solving with delegates you can already solve with existing features of the language i.e. interfaces e.g.

Now around 2001 Microsoft released the .NET framework and the C# language as a competitor solution to Java, so it was good to have NEW FEATURES that Java doesn't have.

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

The following line is looking for the exact NavigableString 'Python':

>>> soup.body.findAll(text='Python')
[]

Note that the following NavigableString is found:

>>> soup.body.findAll(text='Python Jobs') 
[u'Python Jobs']

Note this behaviour:

>>> import re
>>> soup.body.findAll(text=re.compile('^Python$'))
[]

So your regexp is looking for an occurrence of 'Python' not the exact match to the NavigableString 'Python'.

if(listAxu.size() > 0){
     Collections.sort(listAxu, new Comparator<Situacao>(){
        @Override
        public int compare(Situacao lhs, Situacao rhs) {            
            return lhs.getDescricao().compareTo(rhs.getDescricao());
        }
    });
 }

You could use HorizontalContentAlignment="Stretch" as follows:

<ListBox HorizontalContentAlignment="Stretch"/>

bar "$@" will be equivalent to bar "$1" "$2" "$3" "$4"

Notice that the quotation marks are important!

"$@", $@, "$*" or $* will each behave slightly different regarding escaping and concatenation as described in this stackoverflow answer.

One closely related use case is passing all given arguments inside an argument like this:

bash -c "bar \"$1\" \"$2\" \"$3\" \"$4\"".

I use a variation of @kvantour's answer to achieve this:

bash -c "bar $(printf -- '"%s" ' "$@")"

Easiest way is to use --link, however the newer versions of docker are moving away from that and in fact that switch will be removed soon.

The link below offers a nice how too, on connecting two containers. You can skip the attach portion, since that is just a useful how to on adding items to images.

https://deis.com/blog/2016/connecting-docker-containers-1/

The part you are interested in is the communication between two containers. The easiest way, is to refer to the DB container by name from the webserver container.

Example:

you named the db container db1 and the webserver container web0. The containers should both be on the bridge network, which means the web container should be able to connect to the DB container by referring to it's name.

So if you have a web config file for your app, then for DB host you will use the name db1.

if you are using an older version of docker, then you should use --link.

Example:

Step 1: docker run --name db1 oracle/database:12.1.0.2-ee

then when you start the web app. use:

Step 2: docker run --name web0 --link db1 webapp/webapp:3.0

and the web app will be linked to the DB. However, as I said the --link switch will be removed soon.

I'd use docker compose instead, which will build a network for you. However; you will need to download docker compose for your system. https://docs.docker.com/compose/install/#prerequisites

an example setup is like this:

file name is base.yml

version: "2"
services:
  webserver:
    image: "moodlehq/moodle-php-apache:7.1
    depends_on:
      - db
    volumes:
      - "/var/www/html:/var/www/html"
      - "/home/some_user/web/apache2_faildumps.conf:/etc/apache2/conf-enabled/apache2_faildumps.conf"
    environment:
      MOODLE_DOCKER_DBTYPE: pgsql
      MOODLE_DOCKER_DBNAME: moodle
      MOODLE_DOCKER_DBUSER: moodle
      MOODLE_DOCKER_DBPASS: "m@0dl3ing"
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"
  db:
    image: postgres:9
    environment:
      POSTGRES_USER: moodle
      POSTGRES_PASSWORD: "m@0dl3ing"
      POSTGRES_DB: moodle
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"

this will name the network a generic name, I can't remember off the top of my head what that name is, unless you use the --name switch.

IE docker-compose --name setup1 up base.yml

NOTE: if you use the --name switch, you will need to use it when ever calling docker compose, so docker-compose --name setup1 down this is so you can have more then one instance of webserver and db, and in this case, so docker compose knows what instance you want to run commands against; and also so you can have more then one running at once. Great for CI/CD, if you are running test in parallel on the same server.

Docker compose also has the same commands as docker so docker-compose --name setup1 exec webserver do_some_command

best part is, if you want to change db's or something like that for unit test you can include an additional .yml file to the up command and it will overwrite any items with similar names, I think of it as a key=>value replacement.

Example:

db.yml

version: "2"
services:
  webserver:
    environment:
      MOODLE_DOCKER_DBTYPE: oci
      MOODLE_DOCKER_DBNAME: XE
  db:
    image: moodlehq/moodle-db-oracle

Then call docker-compose --name setup1 up base.yml db.yml

This will overwrite the db. with a different setup. When needing to connect to these services from each container, you use the name set under service, in this case, webserver and db.

I think this might actually be a more useful setup in your case. Since you can set all the variables you need in the yml files and just run the command for docker compose when you need them started. So a more start it and forget it setup.

NOTE: I did not use the --port command, since exposing the ports is not needed for container->container communication. It is needed only if you want the host to connect to the container, or application from outside of the host. If you expose the port, then the port is open to all communication that the host allows. So exposing web on port 80 is the same as starting a webserver on the physical host and will allow outside connections, if the host allows it. Also, if you are wanting to run more then one web app at once, for whatever reason, then exposing port 80 will prevent you from running additional webapps if you try exposing on that port as well. So, for CI/CD it is best to not expose ports at all, and if using docker compose with the --name switch, all containers will be on their own network so they wont collide. So you will pretty much have a container of containers.

UPDATE: After using features further and seeing how others have done it for CICD programs like Jenkins. Network is also a viable solution.

Example:

docker network create test_network

The above command will create a "test_network" which you can attach other containers too. Which is made easy with the --network switch operator.

Example:

docker run \
    --detach \
    --name db1 \
    --network test_network \
    -e MYSQL_ROOT_PASSWORD="${DBPASS}" \
    -e MYSQL_DATABASE="${DBNAME}" \
    -e MYSQL_USER="${DBUSER}" \
    -e MYSQL_PASSWORD="${DBPASS}" \
    --tmpfs /var/lib/mysql:rw \
    mysql:5

Of course, if you have proxy network settings you should still pass those into the containers using the "-e" or "--env-file" switch statements. So the container can communicate with the internet. Docker says the proxy settings should be absorbed by the container in the newer versions of docker; however, I still pass them in as an act of habit. This is the replacement for the "--link" switch which is going away. Once the containers are attached to the network you created you can still refer to those containers from other containers using the 'name' of the container. Per the example above that would be db1. You just have to make sure all containers are connected to the same network, and you are good to go.

For a detailed example of using network in a cicd pipeline, you can refer to this link: https://git.in.moodle.com/integration/nightlyscripts/blob/master/runner/master/run.sh

Which is the script that is ran in Jenkins for a huge integration tests for Moodle, but the idea/example can be used anywhere. I hope this helps others.

You don't create subfolders of the drawable folder but rather 'sibling' folders next to it under the /res folder for the different screen densities or screen sizes. The /drawable folder (without any dimension) is mostly used for drawables that don't relate to any screen sizes like selectors.

See this screenshot (use the name drawable-hdpi instead of mipmap-hdpi):

map doesn't relate to a Cartesian product at all, although I imagine someone well versed in functional programming could come up with some impossible to understand way of generating a one using map.

map in Python 3 is equivalent to this:

def map(func, iterable):
    for i in iterable:
        yield func(i)

and the only difference in Python 2 is that it will build up a full list of results to return all at once instead of yielding.

Although Python convention usually prefers list comprehensions (or generator expressions) to achieve the same result as a call to map, particularly if you're using a lambda expression as the first argument:

[func(i) for i in iterable]

As an example of what you asked for in the comments on the question - "turn a string into an array", by 'array' you probably want either a tuple or a list (both of them behave a little like arrays from other languages) -

 >>> a = "hello, world"
 >>> list(a)
['h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']
>>> tuple(a)
('h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd')

A use of map here would be if you start with a list of strings instead of a single string - map can listify all of them individually:

>>> a = ["foo", "bar", "baz"]
>>> list(map(list, a))
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

Note that map(list, a) is equivalent in Python 2, but in Python 3 you need the list call if you want to do anything other than feed it into a for loop (or a processing function such as sum that only needs an iterable, and not a sequence). But also note again that a list comprehension is usually preferred:

>>> [list(b) for b in a]
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

Yeah I did the same thing - create a 'dummy' linear layout which gets initial focus. Furthermore, I set the 'next' focus IDs so the user can't focus it any more after scrolling once:

<LinearLayout 'dummy'>
<EditText et>

dummy.setNextFocusDownId(et.getId());

dummy.setNextFocusUpId(et.getId());

et.setNextFocusUpId(et.getId());

a lot of work just to get rid of focus on a view..

Thanks

If you know how to launch your program from the command line then you can run it from the platformio-ide-terminal package's terminal. See platformio-ide-terminal provides an embedded terminal within the Atom text editor. So you can issue commands, including commands to run your Java program, from within it. To install this package you can use APM with the command:

$ apm install platformio-ide-terminal --no-confirm

Alternatively, you can install it from the command palette with:

• Pressing Ctrl+Shift+P. I am assuming this is the appropriate keyboard shortcut for your platform, as you have dealt ith questions about Ubuntu in the past.
• Type Install Packages and Themes.
• Search for the platformio-ide-terminal.
• Install it.

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); 

Below format try if number is like

ex 1 suppose number like 10.1 if apply below format it will be come as 10.10

ex 2 suppose number like .02 if apply below format it will be come as 0.02

ex 3 suppose number like 0.2 if apply below format it will be come as 0.20

to_char(round(to_number(column_name)/10000000,2),'999999999990D99') as column_name

You can use the @helper Razor directive:

@helper WelcomeMessage(string username)
{
    <p>Welcome, @username.</p>
}

Then you invoke it like this:

@WelcomeMessage("John Smith")

I was in same problem.

Below command solved my problem

pip3 install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.0.0-py3-none-any.whl

to find the list of all the urls based on the python version and CPU or GPU only refer to: https://www.tensorflow.org/install/pip

HTTP Basic + HTTPS is one common method.

You can install Oracle's JDK 1.7 fairly easily too; as an example this is how to install JDK 1.7.0_13;

• Download the JDK from Oracle's site. The download to the newest version is always linked from http://java.oracle.com.

As root, do;

cd /usr/local
tar xzf <the file you just downloaded>

As your normal user, add or change these two lines in your ~/.profile to point to the installation;

export JAVA_HOME=/usr/local/jdk1.7.0_13
export PATH=$PATH:$JAVA_HOME/bin

If it's an update, you may also want to remove the old java installation directory in /usr/local.

Log out and in again (or do . ~/.profile), and everything should just work.

The downside with Oracle's JDK is that it won't update with the rest of your system like OpenJDK will, so I'd mostly consider it if you're running programs that require it.

It is happening because your .bash_profile is not reflecting changes.To reflect it, just use the following command

$ source .bash_profile

Please don't put members into an interface; though it's correct in phrasing. Please don't "delete" an interface.

class IInterface() 
{ 
   Public: 
   Virtual ~IInterface(){}; 
   … 
} 

Class ClassImpl : public IInterface 
{ 
    … 
} 

Int main() 
{ 

  IInterface* pInterface = new ClassImpl(); 
  … 
  delete pInterface; // Wrong in OO Programming, correct in C++.
}

For a GUI approach I would take a look at Activity Monitor under Management and sort by CPU.

My solution, using if..else statement. It is always a good practice if you want to avoid unnecessary frustrations, to check that your variable exists and is set. Otherwise, provide a backup image in case; You can also specify multiple style properties, like background-position: center, etc.

<div [ngStyle]="{'background-image': this.photo ? 'url(' + this.photo + ')' : 'https://placehold.it/70x70', 'background-position': 'center' }"></div>

Another way is:

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

Using getimagesize function, we can also get these properties of that specific image-

<?php

list($width, $height, $type, $attr) = getimagesize("image_name.jpg");

echo "Width: " .$width. "<br />";
echo "Height: " .$height. "<br />";
echo "Type: " .$type. "<br />";
echo "Attribute: " .$attr. "<br />";

//Using array
$arr = array('h' => $height, 'w' => $width, 't' => $type, 'a' => $attr);
?>

Result like this -

Width: 200
Height: 100
Type: 2
Attribute: width='200' height='100'

Type of image consider like -

1 = GIF
2 = JPG
3 = PNG
4 = SWF
5 = PSD
6 = BMP
7 = TIFF(intel byte order)
8 = TIFF(motorola byte order)
9 = JPC
10 = JP2
11 = JPX
12 = JB2
13 = SWC
14 = IFF
15 = WBMP
16 = XBM

One way to achieve this is

>>> pd.DataFrame(np.array([[2, 3, 4]]), columns=['A', 'B', 'C']).append(df, ignore_index=True)
Out[330]: 
   A  B  C
0  2  3  4
1  5  6  7
2  7  8  9

Generally, it's easiest to append dataframes, not series. In your case, since you want the new row to be "on top" (with starting id), and there is no function pd.prepend(), I first create the new dataframe and then append your old one.

ignore_index will ignore the old ongoing index in your dataframe and ensure that the first row actually starts with index 1 instead of restarting with index 0.

Typical Disclaimer: Cetero censeo ... appending rows is a quite inefficient operation. If you care about performance and can somehow ensure to first create a dataframe with the correct (longer) index and then just inserting the additional row into the dataframe, you should definitely do that. See:

>>> index = np.array([0, 1, 2])
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[0:1] = [list(s1), list(s2)]
>>> df2
Out[336]: 
     A    B    C
0    5    6    7
1    7    8    9
2  NaN  NaN  NaN
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[1:] = [list(s1), list(s2)]

So far, we have what you had as df:

>>> df2
Out[339]: 
     A    B    C
0  NaN  NaN  NaN
1    5    6    7
2    7    8    9

But now you can easily insert the row as follows. Since the space was preallocated, this is more efficient.

>>> df2.loc[0] = np.array([2, 3, 4])
>>> df2
Out[341]: 
   A  B  C
0  2  3  4
1  5  6  7
2  7  8  9

You can also invoke methods inside the created object.

You can create object instant by invoking the first constractor and then invoke the first method in the created object.

    Class<?> c = Class.forName("mypackage.MyClass");
    Constructor<?> ctor = c.getConstructors()[0];
    Object object=ctor.newInstance(new Object[]{"ContstractorArgs"});
    c.getDeclaredMethods()[0].invoke(object,Object... MethodArgs);

After 27 years, I too, am uncomfortable developing in an IDE. I tried these suggestions (above) - and probably just didn't follow everything right -- so I did a web-search and found what worked for me at 'http://incise.org/android-development-on-the-command-line.html'.

The answer seemed to be a combination of all the answers above (please tell me if I'm wrong and accept my apologies if so).

As mentioned above, eclipse/adt does not create the necessary ant files. In order to compile without eclipse IDE (and without creating ant scripts):

1) Generate build.xml in your top level directory:

android list targets  (to get target id used below)

android update project --target target_id --name project_name  --path top_level_directory

   ** my sample project had a target_id of 1 and a project name of 't1', and 
   I am building from the top level directory of project
   my command line looks like android update project --target 1 --name t1 --path `pwd`

2) Next I compile the project. I was a little confused by the request to not use 'ant'. Hopefully -- requester meant that he didn't want to write any ant scripts. I say this because the next step is to compile the application using ant

 ant target

    this confused me a little bit, because i thought they were talking about the
    android device, but they're not.  It's the mode  (debug/release)
    my command line looks like  ant debug

3) To install the apk onto the device I had to use ant again:

 ant target install

    ** my command line looked like  ant debug install

4) To run the project on my android phone I use adb.

 adb shell 'am start -n your.project.name/.activity'

    ** Again there was some confusion as to what exactly I had to use for project 
    My command line looked like adb shell 'am start -n com.example.t1/.MainActivity'
    I also found that if you type 'adb shell' you get put to a cli shell interface
    where you can do just about anything from there.

3A) A side note: To view the log from device use:

 adb logcat

3B) A second side note: The link mentioned above also includes instructions for building the entire project from the command.

Hopefully, this will help with the question. I know I was really happy to find anything about this topic here.

From the Java Documentation:

[...] More surprisingly, class Class has been generified. Class literals now function as type tokens, providing both run-time and compile-time type information. This enables a style of static factories exemplified by the getAnnotation method in the new AnnotatedElement interface:

<T extends Annotation> T getAnnotation(Class<T> annotationType); 

This is a generic method. It infers the value of its type parameter T from its argument, and returns an appropriate instance of T, as illustrated by the following snippet:

Author a = Othello.class.getAnnotation(Author.class);

Prior to generics, you would have had to cast the result to Author. Also you would have had no way to make the compiler check that the actual parameter represented a subclass of Annotation. [...]

Well, I never had to use this kind of stuff. Anyone?

Assuming you want product with MIN()imial value in sort column, it would look something like this.

SELECT 
  c.id, c.title, p.id AS product_id, p.title
FROM 
  categories AS c
INNER JOIN (
  SELECT
    p.id, p.category_id, p.title
  FROM
    products AS p
  CROSS JOIN (
    SELECT p.category_id, MIN(sort) AS sort
    FROM products
    GROUP BY category_id
  ) AS sq USING (category_id)
) AS p ON c.id = p.category_id

Most of the suggested solutions can cause a 1 day error depending on the time associated with each date. If you are looking for an integer number of calendar days between to dates, regardless of the time associated with each date, I have found that this works well:

return (dateOne.Value.Date - dateTwo.Value.Date).Days;

I've found some useful hacks on this:

            DirectoryInfo dirinfo = new DirectoryInfo(strMainPath);
            String[] exts = new string[] { "*.jpeg", "*.jpg", "*.gif", "*.tiff", "*.bmp","*.png", "*.JPEG", "*.JPG", "*.GIF", "*.TIFF", "*.BMP","*.PNG" };
            ArrayList files = new ArrayList();
            foreach (string ext in exts)
                files.AddRange(dirinfo.GetFiles(ext).OrderBy(x => x.CreationTime).ToArray());

To expand on the @PostConstruct suggestion in other answers, this really is the best solution, in my opinion.

• It keeps your code decoupled from the Spring API (@PostConstruct is in javax.*)
• It explicitly annotates your init method as something that needs to be called to initialize the bean
• You don't need to remember to add the init-method attribute to your spring bean definition, spring will automatically call the method (assuming you register the annotation-config option somewhere else in the context, anyway).

How about some examples to show it in action...

@Test
public void isInstanceOf() {
    Exception anEx1 = new Exception("ex");
    Exception anEx2 = new RuntimeException("ex");
    RuntimeException anEx3 = new RuntimeException("ex");

    //Base case, handles inheritance
    Assert.assertTrue(anEx1 instanceof Exception);
    Assert.assertTrue(anEx2 instanceof Exception);
    Assert.assertTrue(anEx3 instanceof Exception);

    //Other cases
    Assert.assertFalse(anEx1 instanceof RuntimeException);
    Assert.assertTrue(anEx2 instanceof RuntimeException);
    Assert.assertTrue(anEx3 instanceof RuntimeException);
}

@Test
public void isAssignableFrom() {
    Exception anEx1 = new Exception("ex");
    Exception anEx2 = new RuntimeException("ex");
    RuntimeException anEx3 = new RuntimeException("ex");

    //Correct usage = The base class goes first
    Assert.assertTrue(Exception.class.isAssignableFrom(anEx1.getClass()));
    Assert.assertTrue(Exception.class.isAssignableFrom(anEx2.getClass()));
    Assert.assertTrue(Exception.class.isAssignableFrom(anEx3.getClass()));

    //Incorrect usage = Method parameter is used in the wrong order
    Assert.assertTrue(anEx1.getClass().isAssignableFrom(Exception.class));
    Assert.assertFalse(anEx2.getClass().isAssignableFrom(Exception.class));
    Assert.assertFalse(anEx3.getClass().isAssignableFrom(Exception.class));
}

const dates = getDatesFromDateRange("2014-05-02", "2018-05-12", "YYYY/MM/DD", 1);           
console.log(dates);
// you get the whole from-to date ranges as per parameters
var onlyStartDates = dates.map(dateObj => dateObj["to"]);
console.log(onlyStartDates);
// moreover, if you want only from dates then you can grab by "map" function

function getDatesFromDateRange( startDate, endDate, format, counter ) {
    startDate = moment(startDate, format);
    endDate = moment(endDate, format);

    let dates = [];
    let fromDate = startDate.clone();
    let toDate = fromDate.clone().add(counter, "month").startOf("month").add(-1, "day");
    do {
        dates.push({
            "from": fromDate.format(format),
            "to": ( toDate < endDate ) ? toDate.format(format) : endDate.format(format)
        });
        fromDate = moment(toDate, format).add(1, "day").clone();
        toDate = fromDate.clone().add(counter, "month").startOf("month").add(-1, "day");
    } while ( fromDate < endDate );
    return dates;
}

Please note, .clone() is essential in momentjs else it'll override the value. It seems in your case.

It's more generic, to get bunch of dates that fall between dates.

You can do this:

<select  class='form-control' 
        (change)="ChangingValue($event)" [value]='46'>
  <option value='47'>47</option>
  <option value='46'>46</option>
  <option value='45'>45</option>
</select>

// Note: You can set the value of select only from options tag. In the above example, you cannot set the value of select to anything other than 45, 46, 47.

Here, you can ply with this.

You do need to add a function, but it's a simple one. I use this:

CREATE FUNCTION [dbo].[ufn_GetDaysInMonth] ( @pDate    DATETIME )

RETURNS INT
AS
BEGIN

    SET @pDate = CONVERT(VARCHAR(10), @pDate, 101)
    SET @pDate = @pDate - DAY(@pDate) + 1

    RETURN DATEDIFF(DD, @pDate, DATEADD(MM, 1, @pDate))
END

GO

Here you go:

$.inArray('specialword', arr)

This function returns a positive integer (the array index of the given value), or -1 if the given value was not found in the array.

Live demo: http://jsfiddle.net/simevidas/5Gdfc/

You probably want to use this like so:

if ( $.inArray('specialword', arr) > -1 ) {
    // the value is in the array
}

I converted to this format

let timestamp = '1452488445471';
let newDate = new Date(timestamp * 1000)
let Hours = newDate.getHours()
let Minutes = newDate.getMinutes()
const HourComplete = Hours + ':' + Minutes
let formatedTime = HourComplete
console.log(formatedTime)

jQuery tested method working fine in FF & Chrome:

$(function(){
    $.clearUploadField = function(idsel){
        $('#your-id input[name="'+idsel+'"]').val("") 
    }
});

with open('writing_file.json', 'w') as w:
    with open('reading_file.json', 'r') as r:
        for line in r:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            w.write(json.dumps(element))

this is the method i use..

First get the process id, the first number from the process listed, from one of the following: (or just use ps aux | grep java, if you prefer that)

jps -lvm

Then use the process ID here:

jmap -heap $MY_PID 2>/dev/null | sed -ne '/Heap Configuration/,$p';
jmap -permstat $MY_PID

To clarify why the other answers can not work:

1. System.gc() (along with Runtime.getRuntime().gc(), which does the exact same thing) hints that you want stuff destroyed. Vaguely. The JVM is free to ignore requests to run a GC cycle, if it doesn't see the need for one. Plus, unless you've nulled out all reachable references to the object, GC won't touch it anyway. So A and B are both disqualified.

2. Runtime.getRuntime.gc() is bad grammar. getRuntime is a function, not a variable; you need parentheses after it to call it. So B is double-disqualified.

3. Object has no delete method. So C is disqualified.

4. While Object does have a finalize method, it doesn't destroy anything. Only the garbage collector can actually delete an object. (And in many cases, they technically don't even bother to do that; they just don't copy it when they do the others, so it gets left behind.) All finalize does is give an object a chance to clean up before the JVM discards it. What's more, you should never ever be calling finalize directly. (As finalize is protected, the JVM won't let you call it on an arbitrary object anyway.) So D is disqualified.

5. Besides all that, object.doAnythingAtAllEvenCommitSuicide() requires that running code have a reference to object. That alone makes it "alive" and thus ineligible for garbage collection. So C and D are double-disqualified.

My favoured technique:

signal clk : std_logic := '0'; -- make sure you initialise!
...
clk <= not clk after half_period;

I usually extend this with a finished signal to allow me to stop the clock:

clk <= not clk after half_period when finished /= '1' else '0';

Gotcha alert: Care needs to be taken if you calculate half_period from another constant by dividing by 2. The simulator has a "time resolution" setting, which often defaults to nanoseconds... In which case, 5 ns / 2 comes out to be 2 ns so you end up with a period of 4ns! Set the simulator to picoseconds and all will be well (until you need fractions of a picosecond to represent your clock time anyway!)

print_r($this->session->all_userdata());

Display yet formatting then you can view properly.

Android 4.2 Jelly Bean (API 17) puts the text paddingLeft from the buttonDrawable (ints right edge). It also works for RTL mode.

Before 4.2 paddingLeft was ignoring the buttonDrawable - it was taken from the left edge of the CompoundButton view.

You can solve it via XML - set paddingLeft to buttonDrawable.width + requiredSpace on older androids. Set it to requiredSpace only on API 17 up. For example use dimension resources and override in values-v17 resource folder.

The change was introduced via android.widget.CompoundButton.getCompoundPaddingLeft();

testSpace.Style.Add("display", "none");

If website on small devices behavior like desktop screen then you have to put this meta tag into header before

<meta name="viewport" content="width=device-width, initial-scale=1">

For media queries you can set this as

this will cover your all mobile/cellphone widths

 @media only screen and (min-width: 200px) and (max-width: 767px)  {
    //Put your CSS here for 200px to 767px width devices (cover all width between 200px to 767px //
   
    }

For iPad and iPad pro you have to use

  @media only screen and (min-width: 768px) and (max-width: 1024px)  {
        //Put your CSS here for 768px to 1024px width devices(covers all width between 768px to 1024px //   
  }

If you want to add css for Landscape mode you can add this

and (orientation : landscape)

  @media only screen and (min-width: 200px) and (max-width: 767px) and (orientation : portrait) {
        //Put your CSS here for 200px to 767px width devices (cover all mobile portrait width //        
  }

Sort By Value

  public Map sortByValue(Map map, final boolean ascending) {
            Map result = new LinkedHashMap();
            try {
                List list = new LinkedList(map.entrySet());

                Collections.sort(list, new Comparator() {
                    @Override
                    public int compare(Object object1, Object object2) {
                        if (ascending)
                            return ((Comparable) ((Map.Entry) (object1)).getValue())
                                    .compareTo(((Map.Entry) (object2)).getValue());
                        else
                            return ((Comparable) ((Map.Entry) (object2)).getValue())
                                    .compareTo(((Map.Entry) (object1)).getValue());

                    }
                });

                for (Iterator it = list.iterator(); it.hasNext();) {
                    Map.Entry entry = (Map.Entry) it.next();
                    result.put(entry.getKey(), entry.getValue());
                }

            } catch (Exception e) {
                Log.e("Error", e.getMessage());
            }

            return result;
        }

sometime I need it in objects for xmlhttp calls, so I do like this.

timestamp : parseInt(new Date().getTime()/1000, 10)

Firstly, I would try a non-secure websocket connection. So remove one of the s's from the connection address:

conn = new WebSocket('ws://localhost:8080');

If that doesn't work, then the next thing I would check is your server's firewall settings. You need to open port 8080 both in TCP_IN and TCP_OUT.
