It's important to write full class path in the xml. I got 'Error inflating class' when only subclass's name was written in.

Try calling setWillNotDraw(false) from surfaceCreated:

public void surfaceCreated(SurfaceHolder holder) {
    try {
        setWillNotDraw(false); 
        mycam.setPreviewDisplay(holder);
        mycam.startPreview();
    } catch (Exception e) {
        e.printStackTrace();
        Log.d(TAG,"Surface not created");
    }
}

@Override
protected void onDraw(Canvas canvas) {

    canvas.drawRect(area, rectanglePaint);
    Log.w(this.getClass().getName(), "On Draw Called");
}

and calling invalidate from onTouchEvent:

public boolean onTouch(View v, MotionEvent event) {

    invalidate();
    return true;
}

nodemon is a great one. I just add more parameters for debugging and watching options.

package.json

  "scripts": {
    "dev": "cross-env NODE_ENV=development nodemon --watch server --inspect ./server/server.js"
  }

The command: nodemon --watch server --inspect ./server/server.js

Whereas:

--watch server Restart the app when changing .js, .mjs, .coffee, .litcoffee, and .json files in the server folder (included subfolders).

--inspect Enable remote debug.

./server/server.js The entry point.

Then add the following config to launch.json (VS Code) and start debugging anytime.

{
    "type": "node",
    "request": "attach",
    "name": "Attach",
    "protocol": "inspector",
    "port": 9229
}

Note that it's better to install nodemon as dev dependency of project. So your team members don't need to install it or remember the command arguments, they just npm run dev and start hacking.

See more on nodemon docs: https://github.com/remy/nodemon#monitoring-multiple-directories

I had the same problem after updating of .NET: I uninstalled the .NET framework first, downloaded visual studio from visualstudio.com and selected "repair".

NET framework were installed automatically with visual studio -> and now it works fine!

That's my workaround.

@property
def language(self):
    return self._language
@language.setter
def language(self, value):
    # WORKAROUND to get a "getter-only" behavior
    # set the value only if the attribute does not exist
    try:
        if self.language == value:
            pass
        print("WARNING: Cannot set attribute \'language\'.")
    except AttributeError:
        self._language = value

There is nothing wrong with syntax of

$('#part' + number).html(text);

jQuery accepts a String (usually a CSS Selector) or a DOM Node as parameter to create a jQuery Object.

In your case you should pass a String to $() that is

$(<a string>)

Make sure you have access to the variables number and text.

To test do:

function(){
    alert(number + ":" + text);//or use console.log(number + ":" + text)
    $('#part' + number).html(text);
}); 

If you see you dont have access, pass them as parameters to the function, you have to include the uual parameters for $.get and pass the custom parameters after them.

I was facing the same issue then i made my key 16 byte and it's working properly now. Create your key exactly 16 byte. It will surely work.

From here, you can do this:

/* Extend jQuery with functions for PUT and DELETE requests. */

function _ajax_request(url, data, callback, type, method) {
    if (jQuery.isFunction(data)) {
        callback = data;
        data = {};
    }
    return jQuery.ajax({
        type: method,
        url: url,
        data: data,
        success: callback,
        dataType: type
        });
}

jQuery.extend({
    put: function(url, data, callback, type) {
        return _ajax_request(url, data, callback, type, 'PUT');
    },
    delete_: function(url, data, callback, type) {
        return _ajax_request(url, data, callback, type, 'DELETE');
    }
});

It's basically just a copy of $.post() with the method parameter adapted.

Here is my CORS middleware:

<?php namespace App\Http\Middleware;

use Closure;

class CORS {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

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

        // ALLOW OPTIONS METHOD
        $headers = [
            'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',
            'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'
        ];
        if($request->getMethod() == "OPTIONS") {
            // The client-side application can set only headers allowed in Access-Control-Allow-Headers
            return Response::make('OK', 200, $headers);
        }

        $response = $next($request);
        foreach($headers as $key => $value)
            $response->header($key, $value);
        return $response;
    }

}

To use CORS middleware you have to register it first in your app\Http\Kernel.php file like this:

protected $routeMiddleware = [
        //other middlewares
        'cors' => 'App\Http\Middleware\CORS',
    ];

Then you can use it in your routes

Route::get('example', array('middleware' => 'cors', 'uses' => 'ExampleController@dummy'));

solve(c) does give the correct inverse. The issue with your code is that you are using the wrong operator for matrix multiplication. You should use solve(c) %*% c to invoke matrix multiplication in R.

R performs element by element multiplication when you invoke solve(c) * c.

Python can do unexpected things when new objects are defined from existing ones. You stated in a comment above that your dataframe is defined along the lines of df = df_all.loc[df_all['issueid']==specific_id,:]. In this case, df is really just a stand-in for the rows stored in the df_all object: a new object is NOT created in memory.

To avoid these issues altogether, I often have to remind myself to use the copy module, which explicitly forces objects to be copied in memory so that methods called on the new objects are not applied to the source object. I had the same problem as you, and avoided it using the deepcopy function.

In your case, this should get rid of the warning message:

from copy import deepcopy
df = deepcopy(df_all.loc[df_all['issueid']==specific_id,:])
df['industry'] = 'yyy'

EDIT: Also see David M.'s excellent comment below!

df = df_all.loc[df_all['issueid']==specific_id,:].copy()
df['industry'] = 'yyy'

Although optimally it would be nice if your code can run parallel, it can be the case you're simply using a thread so you do not block the UI thread, even if your app's usage flow will have to wait for it.

You've got pretty much 2 options here;

1. You can execute the code you want waiting, in the AsyncTask itself. If it has to do with updating the UI(thread), you can use the onPostExecute method. This gets called automatically when your background work is done.

2. If you for some reason are forced to do it in the Activity/Fragment/Whatever, you can also just make yourself a custom listener, which you broadcast from your AsyncTask. By using this, you can have a callback method in your Activity/Fragment/Whatever which only gets called when you want it: aka when your AsyncTask is done with whatever you had to wait for.

Here is a way to detect Zombie transaction

SqlTransaction trans = connection.BeginTransaction();

//some db calls here

if (trans.Connection != null) //Detecting zombie transaction
{
  trans.Commit();
}

Decompiling the SqlTransaction class, you will see the following

public SqlConnection Connection
{
  get
  {
    if (this.IsZombied)
      return (SqlConnection) null;
    return this._connection;
  }
}

I notice if the connection is closed, the transOP will become zombie, thus cannot Commit. For my case, it is because I have the Commit() inside a finally block, while the connection was in the try block. This arrangement is causing the connection to be disposed and garbage collected. The solution was to put Commit inside the try block instead.

git config user.name
git config user.email

I believe these are the commands you are looking for.

Here is where I found them: http://alvinalexander.com/git/git-show-change-username-email-address

You'll have to configure the server to interpret .html files as .php files. This configuration is different depending on the server software. This will also add an extra step to the server and will slow down response on all your pages and is probably not ideal.

This can be done using REGEXP_SUBSTR easily.

Please use

REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 

where STRING_EXAMPLE is your string.

Try:

SELECT 
REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 
from dual

It will solve your problem.

This is also promising:

JQuery Drop-Down Combo Box on simpletutorials.com

Calling p.plot after setting the limits is why it is rescaling. You are correct in that turning autoscaling off will get the right answer, but so will calling xlim() or ylim() after your plot command.

I use this quite a lot to invert the x axis, I work in astronomy and we use a magnitude system which is backwards (ie. brighter stars have a smaller magnitude) so I usually swap the limits with

lims = xlim()
xlim([lims[1], lims[0]]) 

This question is the first one that shows up on Google when one looks up "Python how to add elements to set", so it's worth noting explicitly that, if you want to add a whole string to a set, it should be added with .add(), not .update().

Say you have a string foo_str whose contents are 'this is a sentence', and you have some set bar_set equal to set().

If you do bar_set.update(foo_str), the contents of your set will be {'t', 'a', ' ', 'e', 's', 'n', 'h', 'c', 'i'}.

If you do bar_set.add(foo_str), the contents of your set will be {'this is a sentence'}.

Try LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0). Best of all it's free!

Steps with version 4.35.1:

1. click 'Add Connection'

2. Click Next with 'Build data context automatically' and 'Default(LINQ to SQL)' selected.

3. Under 'Provider' choose 'SQL CE 4.0'.

4. Under 'Database' with 'Attach database file' selected, choose 'Browse' to select your .sdf file.

5. Click 'OK'.

6. Voila! It should show the tables in .sdf and be able to query it via right clicking the table or writing LINQ code in your favorite .NET language or even SQL. How cool is that?

Use pd.to_numeric with errors='coerce'

# Setup
s = pd.Series(['1', '2', '3', '4', '.'])
s

0    1
1    2
2    3
3    4
4    .
dtype: object

pd.to_numeric(s, errors='coerce')

0    1.0
1    2.0
2    3.0
3    4.0
4    NaN
dtype: float64

If you need the NaNs filled in, use Series.fillna.

pd.to_numeric(s, errors='coerce').fillna(0, downcast='infer')

0    1
1    2
2    3
3    4
4    0
dtype: float64

Note, downcast='infer' will attempt to downcast floats to integers where possible. Remove the argument if you don't want that.

From v0.24+, pandas introduces a Nullable Integer type, which allows integers to coexist with NaNs. If you have integers in your column, you can use

pd.__version__
# '0.24.1'

pd.to_numeric(s, errors='coerce').astype('Int32')

0      1
1      2
2      3
3      4
4    NaN
dtype: Int32

There are other options to choose from as well, read the docs for more.

Extension for DataFrames

If you need to extend this to DataFrames, you will need to apply it to each row. You can do this using DataFrame.apply.

# Setup.
np.random.seed(0)
df = pd.DataFrame({
    'A' : np.random.choice(10, 5), 
    'C' : np.random.choice(10, 5), 
    'B' : ['1', '###', '...', 50, '234'], 
    'D' : ['23', '1', '...', '268', '$$']}
)[list('ABCD')]
df

   A    B  C    D
0  5    1  9   23
1  0  ###  3    1
2  3  ...  5  ...
3  3   50  2  268
4  7  234  4   $$

df.dtypes

A     int64
B    object
C     int64
D    object
dtype: object

df2 = df.apply(pd.to_numeric, errors='coerce')
df2

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

df2.dtypes

A      int64
B    float64
C      int64
D    float64
dtype: object

You can also do this with DataFrame.transform; although my tests indicate this is marginally slower:

df.transform(pd.to_numeric, errors='coerce')

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

If you have many columns (numeric; non-numeric), you can make this a little more performant by applying pd.to_numeric on the non-numeric columns only.

df.dtypes.eq(object)

A    False
B     True
C    False
D     True
dtype: bool

cols = df.columns[df.dtypes.eq(object)]
# Actually, `cols` can be any list of columns you need to convert.
cols
# Index(['B', 'D'], dtype='object')

df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')
# Alternatively,
# for c in cols:
#     df[c] = pd.to_numeric(df[c], errors='coerce')

df

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

Applying pd.to_numeric along the columns (i.e., axis=0, the default) should be slightly faster for long DataFrames.

For Dart check "Line length" property in Settings.

You don't need to use character codes; just use UTF-8 and put them in literally; like so:

??

If you absolutely must use the entites, they are ▲ and ▼, respectively.

Another method that people should consider using is Shared Workers. I know it's a cutting edge concept, but you can create a relay on a Shared Worker that is MUCH faster than localstorage, and doesn't require a relationship between the parent/child window, as long as you're on the same origin.

See my answer here for some discussion I made about this.

easy but not efficient:

list(df.education).count('9th')

in is the intended way to test for the existence of a key in a dict.

d = {"key1": 10, "key2": 23}

if "key1" in d:
    print("this will execute")

if "nonexistent key" in d:
    print("this will not")

If you wanted a default, you can always use dict.get():

d = dict()

for i in range(100):
    key = i % 10
    d[key] = d.get(key, 0) + 1

and if you wanted to always ensure a default value for any key you can either use dict.setdefault() repeatedly or defaultdict from the collections module, like so:

from collections import defaultdict

d = defaultdict(int)

for i in range(100):
    d[i % 10] += 1

but in general, the in keyword is the best way to do it.

Here is another possible workaround:

if exists (select * from master..sysservers where srvname = 'loopback')
    exec sp_dropserver 'loopback'
go
exec sp_addlinkedserver @server = N'loopback', @srvproduct = N'', @provider = N'SQLOLEDB', @datasrc = @@servername
go

create function testit()
    returns int
as
begin
    declare @res int;
    select @res=count(*) from openquery(loopback, 'exec sp_who');
    return @res
end
go

select dbo.testit()

It's not so scary as xp_cmdshell but also has too many implications for practical use.

I ran into this error when testing my Angular 6 App with Karma/Jasmine. I had already imported FormsModule in my top-level module. But when I added a new component that used [(ngModel)] my tests began failing. In this case, I needed to import FormsModule in my TestBed TestingModule.

beforeEach(async(() => {
  TestBed.configureTestingModule({
    imports: [
      FormsModule
    ],
    declarations: [
      RegisterComponent
    ]
  })
  .compileComponents();
}));

Either:

DateTime dt = new DateTime();

or

DateTime dt = default(DateTime);

According to C17 6.7.2 §2:

Each list of type specifiers shall be one of the following multisets (delimited by commas, when there is more than one multiset per item); the type specifiers may occur in any order, possibly intermixed with the other declaration specifiers

— void
— char
— signed char
— unsigned char
— short, signed short, short int, or signed short int
— unsigned short, or unsigned short int
— int, signed, or signed int
— unsigned, or unsigned int
— long, signed long, long int, or signed long int
— unsigned long, or unsigned long int
— long long, signed long long, long long int, or signed long long int
— unsigned long long, or unsigned long long int
— float
— double
— long double
— _Bool
— float _Complex
— double _Complex
— long double _Complex
— atomic type specifier
— struct or union specifier
— enum specifier
— typedef name

So in case of unsigned int we can either write unsigned or unsigned int, or if we are feeling crazy, int unsigned. The latter since the standard is stupid enough to allow "...may occur in any order, possibly intermixed". This is a known flaw of the language.

Proper C code uses unsigned int.

1) Ensure you're in branch where you need a copy of the file. for eg: i want sub branch file in master so you need to checkout or should be in master git checkout master

2) Now checkout specific file alone you want from sub branch into master,

git checkout sub_branch file_path/my_file.ext

here sub_branch means where you have that file followed by filename you need to copy.

I found a dirty trick but it works, you could use the hover function to get the value before change!

In Visual Studio 2012 all I had to do was enter:

(localdb)\v11.0

Visual Studio 2015 and Visual Studio 2017 changed to:

(localdb)\MSSQLLocalDB

as the server name when adding a Microsoft SQL Server Data source in:

View/Server Explorer/(Right click) Data Connections/Add Connection

and then the database names were populated. I didn't need to do all the other steps in the accepted answer, although it would be nice if the server name was available automatically in the server name combo box.

You can also browse the LocalDB database names available on your machine using:

View/SQL Server Object Explorer.

Another option is to add it to the jest.config.js file after the module.exports definition:

process.env = Object.assign(process.env, {
  VAR_NAME: 'varValue',
  VAR_NAME_2: 'varValue2'
});

This way it's not necessary to define the environment variables in each .spec file and they can be adjusted globally.

Late to the party, but I think this is actually the most elegant. Use the WORD JOINER Unicode character ⁠ on either side of your hyphen, or em dash, or any character.

So, like so:

This will join the symbol on both ends to its neighbors (without adding a space) and prevent line breaking.

Copied from the formal specification: ECMAScript 5.1 section 11.9.5

11.9.4 The Strict Equals Operator ( === )

The production EqualityExpression : EqualityExpression === RelationalExpression is evaluated as follows:

1. Let lref be the result of evaluating EqualityExpression.
2. Let lval be GetValue(lref).
3. Let rref be the result of evaluating RelationalExpression.
4. Let rval be GetValue(rref).
5. Return the result of performing the strict equality comparison rval === lval. (See 11.9.6)

11.9.5 The Strict Does-not-equal Operator ( !== )

The production EqualityExpression : EqualityExpression !== RelationalExpression is evaluated as follows:

1. Let lref be the result of evaluating EqualityExpression.
2. Let lval be GetValue(lref).
3. Let rref be the result of evaluating RelationalExpression.
4. Let rval be GetValue(rref). Let r be the result of performing strict equality comparison rval === lval. (See 11.9.6)
5. If r is true, return false. Otherwise, return true.

11.9.6 The Strict Equality Comparison Algorithm

The comparison x === y, where x and y are values, produces true or false. Such a comparison is performed as follows:

1. If Type(x) is different from Type(y), return false.
2. Type(x) is Undefined, return true.
3. Type(x) is Null, return true.
4. Type(x) is Number, then
   1. If x is NaN, return false.
   2. If y is NaN, return false.
   3. If x is the same Number value as y, return true.
   4. If x is +0 and y is -0, return true.
   5. If x is -0 and y is +0, return true.
   6. Return false.
5. If Type(x) is String, then return true if x and y are exactly the same sequence of characters (same length and same characters in corresponding positions); otherwise, return false.
6. If Type(x) is Boolean, return true if x and y are both true or both false; otherwise, return false.
7. Return true if x and y refer to the same object. Otherwise, return false.

If its simply a case of knowing/seeing who is in a file at any particular time (and if you're using windows) just select the file 'view' as 'details', i.e. rather than Thumbnails, tiles or icons etc. Once in 'details' view, by default you will be shown; - File name - Size - Type, and - Date modified

All you you need to do now is right click anywhere along said toolbar (file name, size, type etc...) and you will be given a list of other options that the toolbar can display.

Select 'Owner' and a new column will show the username of the person using the file or who originally created it if nobody else is using it.

This can be particularly useful when using a shared MS Access database.

Nested classes are very useful for implementing internal details that should not be exposed. If you use Reflector to check classes like Dictionary<Tkey,TValue> or Hashtable you'll find some examples.

=RIGHT(A1)  

is quite sufficient (where the string is contained in A1).

Similar in nature to LEFT, Excel's RIGHT function extracts a substring from a string starting from the right-most character:

SYNTAX

RIGHT( text, [number_of_characters] )

Parameters or Arguments

text

The string that you wish to extract from.

number_of_characters

Optional. It indicates the number of characters that you wish to extract starting from the right-most character. If this parameter is omitted, only 1 character is returned.

Applies To

Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000

Since number_of_characters is optional and defaults to 1 it is not required in this case.

However, there have been many issues with trailing spaces and if this is a risk for the last visible character (in general):

=RIGHT(TRIM(A1))  

might be preferred.

A very useful solution is use the config module.

after install the module:

$ npm install config

You could create a default.json configuration file. (you could use JSON or JS object using extension .json5 )

For example

$ vi config/default.json

{
  "name": "My App Name",
  "configPath": "/my/default/path",
  "port": 3000
}

This default configuration could be override by environment config file or a local config file for a local develop environment:

production.json could be:

{
  "configPath": "/my/production/path",
  "port": 8080
}

development.json could be:

{
  "configPath": "/my/development/path",
  "port": 8081
}

In your local PC you could have a local.json that override all environment, or you could have a specific local configuration as local-production.json or local-development.json.

The full list of load order.

Inside your App

In your app you only need to require config and the needed attribute.

var conf = require('config'); // it loads the right file
var login = require('./lib/everyauthLogin', {configPath: conf.get('configPath'));

Load the App

load the app using:

NODE_ENV=production node app.js

or setting the correct environment with forever or pm2

Forever:

NODE_ENV=production forever [flags] start app.js [app_flags]

PM2 (via shell):

export NODE_ENV=staging
pm2 start app.js

PM2 (via .json):

process.json

{
   "apps" : [{
    "name": "My App",
    "script": "worker.js",
    "env": {
      "NODE_ENV": "development",
    },
    "env_production" : {
       "NODE_ENV": "production"
    }
  }]
}

And then

$ pm2 start process.json --env production

This solution is very clean and it makes easy set different config files for Production/Staging/Development environment and for local setting too.

If you still want a custom filter you can pass in the search model to the filter:

<article data-ng-repeat="result in results | cartypefilter:search" class="result">

Where definition for the cartypefilter can look like this:

app.filter('cartypefilter', function() {
  return function(items, search) {
    if (!search) {
      return items;
    }

    var carType = search.carType;
    if (!carType || '' === carType) {
      return items;
    }

    return items.filter(function(element, index, array) {
      return element.carType.name === search.carType;
    });

  };
});

You can use this function to query for any element on the page, regardless of if it is nested inside of an iframe (or many iframes):

function querySelectorAllInIframes(selector) {
  let elements = [];

  const recurse = (contentWindow = window) => {

    const iframes = contentWindow.document.body.querySelectorAll('iframe');
    iframes.forEach(iframe => recurse(iframe.contentWindow));
    
    elements = elements.concat(contentWindow.document.body.querySelectorAll(selector));
  }

  recurse();

  return elements;
};

querySelectorAllInIframes('#elementToBeFound');

Note: Keep in mind that each of the iframes on the page will need to be of the same-origin, or this function will throw an error.

One module that I have been using for this exact use case is require-all.

It recursively requires all files in a given directory and its sub directories as long they don't match the excludeDirs property.

It also allows specifying a file filter and how to derive the keys of the returned hash from the filenames.

You may want to try jQuery dialog method:

$( ".selector" ).dialog( "moveToTop" );

What eventually worked for me, after lot's of confusing manuals and confusing tutorials, since Docker is obviously at time of my writing at peek of inflated expectations, is:

1. Save the docker image into archive:
   docker save image_name > image_name.tar
2. copy on another machine
3. on that other docker machine, run docker load in a following way:
   cat image_name.tar | docker load

Export and import, as proposed in another answers does not export ports and variables, which might be required for your container to run. And you might end up with stuff like "No command specified" etc... When you try to load it on another machine.

So, difference between save and export is that save command saves whole image with history and metadata, while export command exports only files structure (without history or metadata).

Needless to say is that, if you already have those ports taken on the docker hyper-visor you are doing import, by some other docker container, you will end-up in conflict, and you will have to reconfigure exposed ports.

Note: In order to move data with docker, you might be having persistent storage somewhere, which should also be moved alongside with containers.

Yes,

with open('filename.txt') as fp:
    for line in fp:
        print line

is the way to go.

It is not more verbose. It is more safe.

ou can use String.compareTo(String) that returns an integer that's negative (<), zero(=) or positive(>).

Use it so:

You can use String.compareTo(String) that returns an integer that's negative (<), zero(=) or positive(>).

Use it so:

  String a="myWord";
  if(a.compareTo(another_string) <0){
    //a is strictly < to another_string
  }
  else if (a.compareTo(another_string) == 0){
    //a equals to another_string
  }
else{
  // a is strictly > than another_string
}    

Just to add onto the already great answers, you might want to add multiple labels in your project so doing all of this (setting size, style etc) will be a pain. To solve this, you can create a separate UILabel class.

  import UIKit

  class MyLabel: UILabel {

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        initializeLabel()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        initializeLabel()
    }

    func initializeLabel() {

        self.textAlignment = .left
        self.font = UIFont(name: "Halvetica", size: 17)
        self.textColor = UIColor.white

    }

}

To use it, do the following

import UIKit

class ViewController: UIViewController {

     var myLabel: MyLabel()

     override func viewDidLoad() {
          super.viewDidLoad()

          myLabel = MyLabel(frame: CGRect(x: self.view.frame.size.width / 2, y: self.view.frame.size.height / 2, width: 100, height: 20))
          self.view.addSubView(myLabel)
     }


}

If you give a default value to each primary constructor parameter:

data class Item(var id: String = "",
            var title: String = "",
            var condition: String = "",
            var price: String = "",
            var categoryId: String = "",
            var make: String = "",
            var model: String = "",
            var year: String = "",
            var bodyStyle: String = "",
            var detail: String = "",
            var latitude: Double = 0.0,
            var longitude: Double = 0.0,
            var listImages: List<String> = emptyList(),
            var idSeller: String = "")

and from the class where the instances you can call it without arguments or with the arguments that you have that moment

var newItem = Item()

var newItem2 = Item(title = "exampleTitle",
            condition = "exampleCondition",
            price = "examplePrice",
            categoryId = "exampleCategoryId")

Why don't you just put a hijacked onClick() event handler that will fire only when JS is enabled, and use this to append a parameter (js=true) to the clicked/selected URL (you could also detect a drop down list and change the value- of add a hidden form field). So now when the server sees this parameter (js=true) it knows that JS is enabled and then do your fancy logic server-side.
The down side to this is that the first time a users comes to your site, bookmark, URL, search engine generated URL- you will need to detect that this is a new user so don't look for the NVP appended into the URL, and the server would have to wait for the next click to determine the user is JS enabled/disabled. Also, another downside is that the URL will end up on the browser URL and if this user then bookmarks this URL it will have the js=true NVP, even if the user does not have JS enabled, though on the next click the server would be wise to knowing whether the user still had JS enabled or not. Sigh.. this is fun...

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

If you don't have access to the v$ views (as suggested by Quassnoi) there are two alternatives

select utl_inaddr.get_host_name from dual

and

select sys_context('USERENV','SERVER_HOST') from dual

Personally I'd tend towards the last as it doesn't require any grants/privileges which makes it easier from stored procedures.

Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML. Adding a value of selected to the item we want to appear as a header forces it to show in the first place as a placeholder. Something like:

<option selected disabled>Choose here</option>

The complete markup should be along these lines:

<select>
    <option selected disabled>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

You can take a look at this fiddle, and here's the result:

If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden attribute like so:

<select>
    <option selected disabled hidden>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

Check the fiddle here and the screenshot below.

Here is the solution:

<select>
    <option style="display:none;" selected>Select language</option>
    <option>Option 1</option>
    <option>Option 2</option>
</select>

The readr package has a function to do everything for you.

install.packages("readr") # you only need to do this one time on your system
library(readr)
mystring <- read_file("path/to/myfile.txt")

This replaces the version in the package stringr.

For Linux Run this command

date -d '06/12/2012 07:21:22' +"%s"

For mac OSX run this command

date -j -u -f "%a %b %d %T %Z %Y" "Tue Sep 28 19:35:15 EDT 2010" "+%s"

I personally prefer the "boolean1 ^ boolean2" expression due to its succinctness.

If I was in your situation (working in a team), I would strike a compromise by encapsulating the "boolean1 ^ boolean2" logic in a function with a descriptive name such as "isDifferent(boolean1, boolean2)".

For example, instead of using "boolean1 ^ boolean2", you would call "isDifferent(boolean1, boolean2)" like so:

if (isDifferent(boolean1, boolean2))
{
  //do it
}

Your "isDifferent(boolean1, boolean2)" function would look like:

private boolean isDifferent(boolean1, boolean2)
{
    return boolean1 ^ boolean2;
}

Of course, this solution entails the use of an ostensibly extraneous function call, which in itself is subject to Best Practices scrutiny, but it avoids the verbose (and ugly) expression "(boolean1 && !boolean2) || (boolean2 && !boolean1)"!

If you wanna actually just create remote branch without having the local one, you can do it like this:

git push origin HEAD:refs/heads/foo

It pushes whatever is your HEAD to branch foo that did not exist on the remote.

Bitmap bitmap = BitmapFactory.decodeFile(filePath);

Perl 5.10+ contains the 'smart-match' operator ~~, which returns true if a certain element is contained in an array or hash, and false if it doesn't (see perlfaq4):

The nice thing is that it also supports regexes, meaning that your case-insensitive requirement can easily be taken care of:

use strict;
use warnings;
use 5.010;

my @array  = qw/aaa bbb/;
my $wanted = 'aAa';

say "'$wanted' matches!" if /$wanted/i ~~ @array;   # Prints "'aAa' matches!"

If you are grouping by some other value, then instead of what you have,

write it as

Sum(CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END) as SumSomeProduct

If, otoh, you want to group By the internal expression, (col3*col4) then

write the group By to match the expression w/o the SUM...

Select Sum(Case When col1 > col2 Then col3*col4 Else 0 End) as SumSomeProduct
From ...

Group By Case When col1 > col2 Then col3*col4 Else 0 End 

Finally, if you want to group By the actual aggregate

Select SumSomeProduct, Count(*), <other aggregate functions>
From (Select <other columns you are grouping By>, 
      Sum(Case When col1 > col2 
          Then col3*col4 Else 0 End) as SumSomeProduct
      From Table
      Group By <Other Columns> ) As Z
Group by SumSomeProduct

Open below mention path on your system and delete all your avd's (Virtual devices: Emulator)

C:\Users{Username}.android\avd

Note: - Deleting Emulator only from android studio will not delete all the spaces grab by their avd's. So delete all avd's from above given path and then create new emulator, if you needed.

I want to share an example which made a lot sense to me when I was learning:

This is just an example which does not include the virtual method or the base class. Just to give a hint regarding the main idea.

Let's say there is a Vehicle washing machine and it has a function called as "Wash" and accepts Car as a type.

Gets the Car input and washes the Car.

public void Wash(Car anyCar){
       //wash the car
}

Let's overload Wash() function

Overloading:

public void Wash(Truck anyTruck){
   //wash the Truck  
}

Wash function was only washing a Car before, but now its overloaded to wash a Truck as well.

• If the provided input object is a Car, it will execute Wash(Car anyCar)
• If the provided input object is a Truck, then it will execute Wash(Truck anyTruck)

Let's override Wash() function

Overriding:

public override void Wash(Car anyCar){
   //check if the car has already cleaned
   if(anyCar.Clean){ 
       //wax the car
   }
   else{
       //wash the car
       //dry the car
       //wax the car
   }     
}

Wash function now has a condition to check if the Car is already clean and not need to be washed again.

• If the Car is clean, then just wax it.

• If not clean, then first wash the car, then dry it and then wax it

.

So the functionality has been overridden by adding a new functionality or do something totally different.

I have also tried all the posted code until I found out this one

if(math.toLowerCase(Locale.ENGLISH));

Here whatever character the user input will be converted to lower cases.

Why do you need it to be of type GenericWebApplicationContext?
I think you can probably work with any ApplicationContext type.

Usually you would use an init method (in addition to your setter method):

@PostConstruct
public void init(){
    AutowireCapableBeanFactory bf = this.applicationContext
        .getAutowireCapableBeanFactory();
    // wire stuff here
}

And you would wire beans by using either

AutowireCapableBeanFactory.autowire(Class, int mode, boolean dependencyInject)

or

AutowireCapableBeanFactory.initializeBean(Object existingbean, String beanName)

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

Element is the only kind of node that can have child nodes and attributes.

Document also has child nodes, BUT
no attributes, no text, exactly one child element.

This might work for you:

sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1

There is a trick to push postgres to prefer a seqscan adding a OFFSET 0 in the subquery

This is handy for optimizing requests linking big/huge tables when all you need is only the n first/last elements.

Lets say you are looking for first/last 20 elements involving multiple tables having 100k (or more) entries, no point building/linking up all the query over all the data when what you'll be looking for is in the first 100 or 1000 entries. In this scenario for example, it turns out to be over 10x faster to do a sequential scan.

see How can I prevent Postgres from inlining a subquery?

' is valid in HTML5, but not HTML4. However, most browsers support ' for HTML4 anyway.

Selenium2Library has get_location():

import Selenium2Library

url = s.get_location()

Another alternative

char[] c = { 'R', 'o', 'c', 'k', '-', '&', '-', 'R', 'o', 'l', 'l' };
string s = String.Concat( c );

Debug.Assert( s.Equals( "Rock-&-Roll" ) );

I created a JS fiddle for this here:

http://jsfiddle.net/Barzi/Jzs6B/9/

First, your HTML markup looks like this:

<video id="videoarea" controls="controls" poster="" src=""></video>

<ul id="playlist">
    <li movieurl="VideoURL1.webm" moviesposter="VideoPoster1.jpg">First video</li>
    <li movieurl="VideoURL2.webm">Second video</li>
    ...
    ...
</ul>

Second, your JavaScript code via JQuery library will look like this:

$(function() {
    $("#playlist li").on("click", function() {
        $("#videoarea").attr({
            "src": $(this).attr("movieurl"),
            "poster": "",
            "autoplay": "autoplay"
        })
    })
    $("#videoarea").attr({
        "src": $("#playlist li").eq(0).attr("movieurl"),
        "poster": $("#playlist li").eq(0).attr("moviesposter")
    })
})?

And last but not least, your CSS:

#playlist {
    display:table;
}
#playlist li{
    cursor:pointer;
    padding:8px;
}
#playlist li:hover{
    color:blue;                        
}
#videoarea {
    float:left;
    width:640px;
    height:480px;
    margin:10px;    
    border:1px solid silver;
}?

You didn't do what you're being asked to do.

What is asked:

I have to execute ../gradlew build

What you do

cd ..
gradlew build

That's not the same thing.

The first one will use the gradlew command found in the .. directory (mdeinum...), and look for the build file to execute in the current directory, which is (for example) chapter1-bookstore.

The second one will execute the gradlew command found in the current directory (mdeinum...), and look for the build file to execute in the current directory, which is mdeinum....

So the build file executed is not the same.

For :

abc:number|string;

Use the JavaScript operator typeof:

if (typeof abc === "number") {
    // do something
}

TypeScript understands typeof

This is called a typeguard.

For classes you would use instanceof e.g.

class Foo {}
class Bar {} 

// Later
if (fooOrBar instanceof Foo){
  // TypeScript now knows that `fooOrBar` is `Foo`
}

There are also other type guards e.g. in etc https://basarat.gitbooks.io/typescript/content/docs/types/typeGuard.html

Example of using a function() in bash:

#!/bin/bash
# file.sh: a sample shell script to demonstrate the concept of Bash shell functions
# define usage function
usage(){
    echo "Usage: $0 filename"
    exit 1
}

# define is_file_exists function
# $f -> store argument passed to the script
is_file_exists(){
    local f="$1"
    [[ -f "$f" ]] && return 0 || return 1
}
# invoke  usage
# call usage() function if filename not supplied
[[ $# -eq 0 ]] && usage

# Invoke is_file_exits
if ( is_file_exists "$1" )
then
 echo "File found: $1"
else
 echo "File not found: $1"
fi

What worked for me:

Preferences-General-Default working directory-Browse Switch from global to local mirror

Working on a Mac. 10.10.3

It looks like the only way to achieve this is by setting

browser.display.focus_ring_width = 0

in about:config on a per browser basis.

Other answers explain what mocking is. Let me walk you through it with different examples. And believe me, it's actually far more simpler than you think.

tl;dr It's an instance of the original class. It has other data injected into so you avoid testing the injected parts and solely focus on testing the implementation details of your class/functions.

Simple example:

class Foo {
    func add (num1: Int, num2: Int) -> Int { // Line A 
        return num1 + num2 // Line B
    }
}

let unit = Foo() // unit under test
assertEqual(unit.add(1,5),6)

As you can see, I'm not testing LineA ie I'm not validating the input parameters. I'm not validating to see if num1, num2 are an Integer. I have no asserts against that.

I'm only testing to see if LineB (my implementation) given the mocked values 1 and 5 is doing as I expect.

Obviously in the real word this can become much more complex. The parameters can be a custom object like a Person, Address, or the implementation details can be more than a single +. But the logic of testing would be the same.

Non-coding Example:

Assume you're building a machine that identifies the type and brand name of electronic devices for an airport security. The machine does this by processing what it sees with its camera.

Now your manager walks in the door and asks you to unit-test it.

Then you as a developer you can either bring 1000 real objects, like a MacBook pro, Google Nexus, a banana, an iPad etc in front of it and test and see if it all works.

But you can also use mocked objects, like an identical looking MacBook pro (with no real internal parts) or a plastic banana in front of it. You can save yourself from investing in 1000 real laptops and rotting bananas.

The point is you're not trying to test if the banana is fake or not. Nor testing if the laptop is fake or not. All you're doing is testing if your machine once it sees a banana it would say not an electronic device and for a MacBook Pro it would say: Laptop, Apple. To the machine, the outcome of its detection should be the same for fake/mocked electronics and real electronics. If your machine also factored in the internals of a laptop (x-ray scan) or banana then your mocks' internals need to look the same as well. But you could also use a gadget with a friend motherboard. Had your machine tested whether or not devices can power on then well you'd need real devices.

The logic mentioned above applies to unit-testing of actual code as well. That is a function should work the same with real values you get from real input (and interactions) or mocked values you inject during unit-testing. And just as how you save yourself from using a real banana or MacBook, with unit-tests (and mocking) you save yourself from having to do something that causes your server to return a status code of 500, 403, 200, etc (forcing your server to trigger 500 is only when server is down, while 200 is when server is up. It gets difficult to run 100 network focused tests if you have to constantly wait 10 seconds between switching over server up and down). So instead you inject/mock a response with status code 500, 200, 403, etc and test your unit/function with a injected/mocked value.

Be aware:

Sometimes you don't correctly mock the actual object. Or you don't mock every possibility. E.g. your fake laptops are dark, and your machine accurately works with them, but then it doesn't work accurately with white fake laptops. Later when you ship this machine to customers they complain that it doesn't work all the time. You get random reports that it's not working. It takes you 3 months of time to finally figure out that the color of fake laptops need to be more varied so you can test your modules appropriately.

For a true coding example, your implementation may be different for status code 200 with image data returned vs 200 with image data not returned. For this reason it's good to use an IDE that provides code coverage e.g. the image below shows that your unit-tests don't ever go through the lines marked with brown.

Real world coding Example:

Let's say you are writing an iOS application and have network calls.Your job is to test your application. To test/identify whether or not the network calls work as expected is NOT YOUR RESPONSIBILITY . It's another party's (server team) responsibility to test it. You must remove this (network) dependency and yet continue to test all your code that works around it.

A network call can return different status codes 404, 500, 200, 303, etc with a JSON response.

Your app is suppose to work for all of them (in case of errors, your app should throw its expected error). What you do with mocking is you create 'imaginary—similar to real' network responses (like a 200 code with a JSON file) and test your code without 'making the real network call and waiting for your network response'. You manually hardcode/return the network response for ALL kinds of network responses and see if your app is working as you expect. (you never assume/test a 200 with incorrect data, because that is not your responsibility, your responsibility is to test your app with a correct 200, or in case of a 400, 500, you test if your app throws the right error)

This creating imaginary—similar to real is known as mocking.

In order to do this, you can't use your original code (your original code doesn't have the pre-inserted responses, right?). You must add something to it, inject/insert that dummy data which isn't normally needed (or a part of your class).

So you create an instance the original class and add whatever (here being the network HTTPResponse, data OR in the case of failure, you pass the correct errorString, HTTPResponse) you need to it and then test the mocked class.

Long story short, mocking is to simplify and limit what you are testing and also make you feed what a class depends on. In this example you avoid testing the network calls themselves, and instead test whether or not your app works as you expect with the injected outputs/responses —— by mocking classes

_{Needless to say, you test each network response separately.}

Now a question that I always had in my mind was: The contracts/end points and basically the JSON response of my APIs get updated constantly. How can I write unit tests which take this into consideration?

To elaborate more on this: let’s say model requires a key/field named username. You test this and your test passes. 2 weeks later backend changes the key's name to id. Your tests still passes. right? or not?

Is it the backend developer’s responsibility to update the mocks. Should it be part of our agreement that they provide updated mocks?

The answer to the above issue is that: unit tests + your development process as a client-side developer should/would catch outdated mocked response. If you ask me how? well the answer is:

Our actual app would fail (or not fail yet not have the desired behavior) without using updated APIs...hence if that fails...we will make changes on our development code. Which again leads to our tests failing....which we’ll have to correct it. (Actually if we are to do the TDD process correctly we are to not write any code about the field unless we write the test for it...and see it fail and then go and write the actual development code for it.)

This all means that backend doesn’t have to say: “hey we updated the mocks”...it eventually happens through your code development/debugging. ??Because it’s all part of the development process! Though if backend provides the mocked response for you then it's easier.

My whole point on this is that (if you can’t automate getting updated mocked API response then) some human interaction is required ie manual updates of JSONs and having short meetings to make sure their values are up to date will become part of your process

_{This section was written thanks to a slack discussion in our CocoaHead meetup group}

For iOS devs only:

A very good example of mocking is this Practical Protocol-Oriented talk by Natasha Muraschev. Just skip to minute 18:30, though the slides may become out of sync with the actual video ???

I really like this part from the transcript:

Because this is testing...we do want to make sure that the get function from the Gettable is called, because it can return and the function could theoretically assign an array of food items from anywhere. We need to make sure that it is called;

This command:

iconv -f utf-8 -t utf-8 -c file.txt

will clean up your UTF-8 file, skipping all the invalid characters.

-f is the source format
-t the target format
-c skips any invalid sequence

You can use killall command as well .

-o, --older-than Match only processes that are older (started before) the time specified. The time is specified as a float then a unit. The units are s,m,h,d,w,M,y for seconds, minutes, hours, days,

-e, --exact Require an exact match for very long names.

-r, --regexp Interpret process name pattern as an extended regular expression.

This worked like a charm.

Since std::string in C++ is mutable you can use that. It has a += operator and an append function.

If you need to append numerical data use the std::to_string functions.

If you want even more flexibility in the form of being able to serialise any object to a string then use the std::stringstream class. But you'll need to implement your own streaming operator functions for it to work with your own custom classes.

If your rotation angles are fairly uniform, you can use CSS:

<img id="image_canv" src="/image.png" class="rotate90">

CSS:

.rotate90 {
    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -o-transform: rotate(90deg);
    -ms-transform: rotate(90deg);
    transform: rotate(90deg);
}

Otherwise, you can do this by setting a data attribute in your HTML, then using Javascript to add the necessary styling:

<img id="image_canv" src="/image.png" data-rotate="90">

Sample jQuery:

$('img').each(function() {
    var deg = $(this).data('rotate') || 0;
    var rotate = 'rotate(' + deg + 'deg)';
    $(this).css({ 
        '-webkit-transform': rotate,
        '-moz-transform': rotate,
        '-o-transform': rotate,
        '-ms-transform': rotate,
        'transform': rotate 
    });
});

Demo:

Try this (it's VB-Code :-):

Try

Catch exp As WebException
  Dim sResponse As String = New StreamReader(exp.Response.GetResponseStream()).ReadToEnd
End Try

The checking of the presence of the member before assigning it is, in my opinion, quite ugly.

Kohana has a useful function to make selecting parameters simple.

You can make your own like so...

function arrayGet($array, $key, $default = NULL)
{
    return isset($array[$key]) ? $array[$key] : $default;
}

And then do something like...

$page = arrayGet($_GET, 'p', 1);

You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:

>>> print(etree.tostring(root, pretty_print=True))
<root>
  <child1/>
  <child2/>
  <child3/>
</root>

Using only CSS it is not possible at all to add links :) It is not possible to link a background-image, nor a part of it, using HTML/CSS. However, it can be staged using this method:

<div class="wrapWithBackgroundImage">
    <a href="#" class="invisibleLink"></a>
</div>

.wrapWithBackgroundImage {
    background-image: url(...);
}
.invisibleLink {
    display: block;
    left: 55px; top: 55px;
    position: absolute;
    height: 55px width: 55px;
}

For Python 3+

for i in range(5):
    print(str(i) + '\r', sep='', end ='', file = sys.stdout , flush = False)

Here is an example that works on Chrome 5.0.375.125.

The page B (iframe content):

<html>
    <head></head>
    <body>
        <script>
            top.postMessage('hello', 'A');
        </script>
    </body>
</html>

Note the use of top.postMessage or parent.postMessage not window.postMessage here

The page A:

<html>
<head></head>
<body>
    <iframe src="B"></iframe>
    <script>
        window.addEventListener( "message",
          function (e) {
                if(e.origin !== 'B'){ return; } 
                alert(e.data);
          },
          false);
    </script>
</body>
</html>

A and B must be something like http://domain.com

EDIT:

From another question, it looks the domains(A and B here) must have a / for the postMessage to work properly.

I'm not sure how far it will get you, but you can execute JavaScript one line at a time from the Developer Tool Console.

// is floor division, it will always give you the integer floor of the result. The other is 'regular' division.

map[key] = value is provided for easier syntax. It is easier to read and write.

The reason for which you need to have default constructor is that map[key] is evaluated before assignment. If key wasn't present in map, new one is created (with default constructor) and reference to it is returned from operator[].

There is no way to declare global variables as you're probably imagining them in VB.NET.

What you can do (as some of the other answers have suggested) is declare everything that you want to treat as a global variable as static variables instead within one particular class:

Public Class GlobalVariables
    Public Shared UserName As String = "Tim Johnson"
    Public Shared UserAge As Integer = 39
End Class

However, you'll need to fully-qualify all references to those variables anywhere you want to use them in your code. In this sense, they are not the type of global variables with which you may be familiar from other languages, because they are still associated with some particular class.

For example, if you want to display a message box in your form's code with the user's name, you'll have to do something like this:

Public Class Form1: Inherits Form

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        MessageBox.Show("Hello, " & GlobalVariables.UserName)
    End Sub

End Class

You can't simply access the variable by typing UserName outside of the class in which it is defined—you must also specify the name of the class in which it is defined.

If the practice of fully-qualifying your variables horrifies or upsets you for whatever reason, you can always import the class that contains your global variable declarations (here, GlobalVariables) at the top of each code file (or even at the project level, in the project's Properties window). Then, you could simply reference the variables by their name.

Imports GlobalVariables

Note that this is exactly the same thing that the compiler is doing for you behind-the-scenes when you declare your global variables in a Module, rather than a Class. In VB.NET, which offers modules for backward-compatibility purposes with previous versions of VB, a Module is simply a sealed static class (or, in VB.NET terms, Shared NotInheritable Class). The IDE allows you to call members from modules without fully-qualifying or importing a reference to them. Even if you decide to go this route, it's worth understanding what is happening behind the scenes in an object-oriented language like VB.NET. I think that as a programmer, it's important to understand what's going on and what exactly your tools are doing for you, even if you decide to use them. And for what it's worth, I do not recommend this as a "best practice" because I feel that it tends towards obscurity and clean object-oriented code/design. It's much more likely that a C# programmer will understand your code if it's written as shown above than if you cram it into a module and let the compiler handle everything.

Note that like at least one other answer has alluded to, VB.NET is a fully object-oriented language. That means, among other things, that everything is an object. Even "global" variables have to be defined within an instance of a class because they are objects as well. Any time you feel the need to use global variables in an object-oriented language, that a sign you need to rethink your design. If you're just making the switch to object-oriented programming, it's more than worth your while to stop and learn some of the basic patterns before entrenching yourself any further into writing code.

private void button4_Click(object sender, EventArgs e)
    {
        String st = "DELETE FROM supplier WHERE supplier_id =" + textBox1.Text;

        SqlCommand sqlcom = new SqlCommand(st, myConnection);
        try
        {
            sqlcom.ExecuteNonQuery();
            MessageBox.Show("????");
        }
        catch (SqlException ex)
        {
            MessageBox.Show(ex.Message);
        }
    }



    private void button6_Click(object sender, EventArgs e)
    {
        String st = "SELECT * FROM suppliers";

        SqlCommand sqlcom = new SqlCommand(st, myConnection);
        try
        {
            sqlcom.ExecuteNonQuery();
            SqlDataReader reader = sqlcom.ExecuteReader();
            DataTable datatable = new DataTable();
            datatable.Load(reader);
            dataGridView1.DataSource = datatable;
            //MessageBox.Show("LEFT OUTER??");
        }
        catch (SqlException ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

Thats where asp.net puts dynamically compiled assemblies.

Java 9+:

private byte[] loadPEM(String resource) throws IOException {
    URL url = getClass().getResource(resource);
    InputStream in = url.openStream();
    String pem = new String(in.readAllBytes(), StandardCharsets.ISO_8859_1);
    Pattern parse = Pattern.compile("(?m)(?s)^---*BEGIN.*---*$(.*)^---*END.*---*$.*");
    String encoded = parse.matcher(pem).replaceFirst("$1");
    return Base64.getMimeDecoder().decode(encoded);
}

@Test
public void test() throws Exception {
    KeyFactory kf = KeyFactory.getInstance("RSA");
    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    PrivateKey key = kf.generatePrivate(new PKCS8EncodedKeySpec(loadPEM("test.key")));
    PublicKey pub = kf.generatePublic(new X509EncodedKeySpec(loadPEM("test.pub")));
    Certificate crt = cf.generateCertificate(getClass().getResourceAsStream("test.crt"));
}

Java 8:

replace the in.readAllBytes() call with a call to this:

byte[] readAllBytes(InputStream in) throws IOException {
    ByteArrayOutputStream baos= new ByteArrayOutputStream();
    byte[] buf = new byte[1024];
    for (int read=0; read != -1; read = in.read(buf)) { baos.write(buf, 0, read); }
    return baos.toByteArray();
}

Why don't try to use bootstrap's solutions. They are perfect if you don't want to meddle with tables and floats.

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/> <!--- This line is just linking the bootstrap thingie in the file. The real thing starts below -->_x000D_

No meddling with complex CSS, and the best thing is that you can edit the width of the columns by changing the number. You can find more examples at https://getbootstrap.com/docs/4.0/layout/grid/

"How do I for example read a 3 bit integer value starting at the second bit?"

int number = // whatever;
uint8_t val; // uint8_t is the smallest data type capable of holding 3 bits
val = (number & (1 << 2 | 1 << 3 | 1 << 4)) >> 2;

(I assumed that "second bit" is bit #2, i. e. the third bit really.)

try this:

puts 'one TWO three foUR'.split.map(&:capitalize).join(' ')

#=> One Two Three Four

or

puts 'one TWO three foUR'.split.map(&:capitalize)*' '

You can't. You need to create another php script to return the image data, e.g. getImage.php. Change catalog.php to:

<body>
<img src="getImage.php?id=1" width="175" height="200" />
</body>

Then getImage.php is

<?php

  $id = $_GET['id'];
  // do some validation here to ensure id is safe

  $link = mysql_connect("localhost", "root", "");
  mysql_select_db("dvddb");
  $sql = "SELECT dvdimage FROM dvd WHERE id=$id";
  $result = mysql_query("$sql");
  $row = mysql_fetch_assoc($result);
  mysql_close($link);

  header("Content-type: image/jpeg");
  echo $row['dvdimage'];
?>

If you are after performance, try to avoid using AngularJS filters as they are applied twice per each expression to check for their stability.

A better way would be to use CSS ::first-letter pseudo-element with text-transform: uppercase;. That can't be used on inline elements such as span, though, so the next best thing would be to use text-transform: capitalize; on the whole block, which capitalizes every word.

Example:

var app = angular.module('app', []);_x000D_
_x000D_
app.controller('Ctrl', function ($scope) {_x000D_
   $scope.msg = 'hello, world.';_x000D_
});

.capitalize {_x000D_
  display: inline-block;  _x000D_
}_x000D_
_x000D_
.capitalize::first-letter {_x000D_
  text-transform: uppercase;_x000D_
}_x000D_
_x000D_
.capitalize2 {_x000D_
  text-transform: capitalize;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<div ng-app="app">_x000D_
    <div ng-controller="Ctrl">_x000D_
        <b>My text:</b> <div class="capitalize">{{msg}}</div>_x000D_
        <p><b>My text:</b> <span class="capitalize2">{{msg}}</span></p>_x000D_
    </div>_x000D_
</div>

I think due to the dynamic nature of python people don't often see the need for another dynamic framework. When a class inherits from the new-style 'object' you can create a new variable dynamically (https://wiki.python.org/moin/NewClassVsClassicClass).

i.e. In plain python:

#application.py
class Application(object):
    def __init__(self):
        pass

#main.py
Application.postgres_connection = PostgresConnection()

#other.py
postgres_connection = Application.postgres_connection
db_data = postgres_connection.fetchone()

However have a look at https://github.com/noodleflake/pyioc this might be what you are looking for.

i.e. In pyioc

from libs.service_locator import ServiceLocator

#main.py
ServiceLocator.register(PostgresConnection)

#other.py
postgres_connection = ServiceLocator.resolve(PostgresConnection)
db_data = postgres_connection.fetchone()

There will definitely be an open bracket which caused the error.

I'd suggest that you open the page in Firefox, then open Firebug and check the console – it'll show the missing symbol.

Yes to both questions. The using statement gets compiled into a try/finally block

using (SqlConnection connection = new SqlConnection(connectionString))

is the same as

SqlConnection connection = null;
try

    connection = new SqlConnection(connectionString);
}
finally
{
   if(connection != null)
        ((IDisposable)connection).Dispose();
}

Your condition id !== 0 will always be different that zero because you are assigning a string value. On pages where the element with id views_slideshow_controls_text_next_slideshow-block is not found, you will still try to append the img element, which causes the Cannot read property 'appendChild' of null error.

Instead of assigning a string value, you can assign the DOM element and verify if it exists within the page.

window.onload = function loadContIcons() {
    var elem = document.createElement("img");
    elem.src = "http://arno.agnian.com/sites/all/themes/agnian/images/up.png";
    elem.setAttribute("class", "up_icon");

    var container = document.getElementById("views_slideshow_controls_text_next_slideshow-block");
    if (container !== null) {
        container.appendChild(elem);
    } else console.log("aaaaa");

    var elem1 = document.createElement("img");
    elem1.src = "http://arno.agnian.com/sites/all/themes/agnian/images/down.png";
    elem1.setAttribute("class", "down_icon");

    container = document.getElementById("views_slideshow_controls_text_previous_slideshow-block");
    if (container !== null) {
        container.appendChild(elem1);
    } else console.log("aaaaa");
}

Your code is doing a log of a number that is less than or equal to zero. That's mathematically undefined, so Python's log function raises an exception. Here's an example:

>>> from math import log
>>> log(-1)
Traceback (most recent call last):
  File "<pyshell#59>", line 1, in <module>
    log(-1)
ValueError: math domain error

Without knowing what your newtonRaphson2 function does, I'm not sure I can guess where the invalid x[2] value is coming from, but hopefully this will lead you on the right track.

The awk is ok. I'm guessing the file is from a windows system and has a CR (^m ascii 0x0d) on the end of the line.

This will cause the cursor to go to the start of the line after $2.

Use dos2unix or vi with :se ff=unix to get rid of the CRs.

  A 64x64 pixel image with 10 pixel wide paddings from all sides. You are supposed to have 8 pixel wide paddings, but I find most default items being slightly smaller than that. Of course, you'll want to use different sizes for different densities.

  Here we make it clickable and updatable! I created an abstract listener that provides Toast creation on onLongClick, the code was taken from from the sources of ActionBarSherlock.

  private int hot_number = 0;
  private TextView ui_hot = null;
  
  @Override public boolean onCreateOptionsMenu(final Menu menu) {
      MenuInflater menuInflater = getSupportMenuInflater();
      menuInflater.inflate(R.menu.menu_actionbar, menu);
      final View menu_hotlist = menu.findItem(R.id.menu_hotlist).getActionView();
      ui_hot = (TextView) menu_hotlist.findViewById(R.id.hotlist_hot);
      updateHotCount(hot_number);
      new MyMenuItemStuffListener(menu_hotlist, "Show hot message") {
          @Override
          public void onClick(View v) {
              onHotlistSelected();
          }
      };
      return super.onCreateOptionsMenu(menu);
  }
  
  // call the updating code on the main thread,
  // so we can call this asynchronously
  public void updateHotCount(final int new_hot_number) {
      hot_number = new_hot_number;
      if (ui_hot == null) return;
      runOnUiThread(new Runnable() {
          @Override
          public void run() {
              if (new_hot_number == 0)
                  ui_hot.setVisibility(View.INVISIBLE);
              else {
                  ui_hot.setVisibility(View.VISIBLE);
                  ui_hot.setText(Integer.toString(new_hot_number));
              }
          }
      });
  }
  
  static abstract class MyMenuItemStuffListener implements View.OnClickListener, View.OnLongClickListener {
      private String hint;
      private View view;
  
      MyMenuItemStuffListener(View view, String hint) {
          this.view = view;
          this.hint = hint;
          view.setOnClickListener(this);
          view.setOnLongClickListener(this);
      }
  
      @Override abstract public void onClick(View v);

          final int[] screenPos = new int[2];
          final Rect displayFrame = new Rect();
          view.getLocationOnScreen(screenPos);
          view.getWindowVisibleDisplayFrame(displayFrame);
          final Context context = view.getContext();
          final int width = view.getWidth();
          final int height = view.getHeight();
          final int midy = screenPos[1] + height / 2;
          final int screenWidth = context.getResources().getDisplayMetrics().widthPixels;
          Toast cheatSheet = Toast.makeText(context, hint, Toast.LENGTH_SHORT);
          if (midy < displayFrame.height()) {
              cheatSheet.setGravity(Gravity.TOP | Gravity.RIGHT,
                      screenWidth - screenPos[0] - width / 2, height);

For many types (integer, double, DateTime etc), there is a static Parse method. You can invoke it using reflection:

MethodInfo m = typeof(T).GetMethod("Parse", new Type[] { typeof(string) } );

if (m != null)
{
    return m.Invoke(null, new object[] { base.Value });
}

import java.util.ArrayList;

public class TestClass {

public static void main(String[] args) {

    ArrayList<ArrayList<String>> listOLists = new ArrayList<ArrayList<String>>();
    ArrayList<String> List_1 = new ArrayList<String>();
    List_1.add("1");
    List_1.add("2");
    listOLists.add(List_1);

    ArrayList<String> List_2 = new ArrayList<String>();
    List_2.add("4");
    List_2.add("5");
    List_2.add("10");
    List_2.add("11");
    listOLists.add(List_2);
    for (int i = 0; i < listOLists.size(); i++) {
        System.out.print("list " + i + " :");
        for (int j = 0; j < listOLists.get(i).size(); j++) {
            System.out.print(listOLists.get(i).get(j) + " ;");
        }
        System.out.println();
    }

}

}

I hope this solution gives a better picture of list if lists

IList<string> list = new List<string> {"test1", "test2", "test3"}

In C if you implement count line it will never fail. Yes you can get one extra line if there is stray "ENTER KEY" generally at the end of the file.

File might look some thing like this:

"hello 1
"Hello 2

"

Code below

#include <stdio.h>
#include <stdlib.h>
#define FILE_NAME "file1.txt"

int main() {

    FILE *fd = NULL;
    int cnt, ch;

    fd = fopen(FILE_NAME,"r");
    if (fd == NULL) {
            perror(FILE_NAME);
            exit(-1);
    }

    while(EOF != (ch = fgetc(fd))) {
    /*
     * int fgetc(FILE *) returns unsigned char cast to int
     * Because it has to return EOF or error also.
     */
            if (ch == '\n')
                    ++cnt;
    }

    printf("cnt line in %s is %d\n", FILE_NAME, cnt);

    fclose(fd);
    return 0;
}

I have been suffering of this issue for very long time. I was unable to open websites like GitHub. I almost tried all the answer on web and not anyone worked. Tried to reinstall chrome also. I found the solution for this from our network guy and it worked. There is a fix in registry which will resolve this error for permanent basis.

1. Press Windows+R key to open run dialogue box
2. type : regeditand press enter to open registry
3. In the tree view at left click through following path HKEY_LOCAL_MACHINE > SOFTWARE > POLICIES > Microsoft > SystemCertificate > Authroot
4. Now double click on DisableRootAutoUpdate on the right and set it to 0(zero) in the dialogue box appearing
5. Restart your PC to apply registry changes and you will not get this error anymore

The solution above is for Windows 8. It is almost identical in later versions but i’m not sure for earlier versions like XP and vista. So that needs to be checked.

Multithreading Multithreading extends the idea of multitasking into applications, so you can subdivide specific operations within a single application into individual threads.

Use wildcards:

cp /home/ankur/folder/* /home/ankur/dest

If you don't want to copy all the files, you can use braces to select files:

cp /home/ankur/folder/{file{1,2},xyz,abc} /home/ankur/dest

This will copy file1, file2, xyz, and abc.

You should read the sections of the bash man page on Brace Expansion and Pathname Expansion for all the ways you can simplify this.

Another thing you can do is cd /home/ankur/folder. Then you can type just the filenames rather than the full pathnames, and you can use filename completion by typing Tab.

You cannot create a table with a name that is identical to an existing table or view in the cluster. To modify an existing table, use ALTER TABLE (link), or to drop all data currently in the table and create an empty table with the desired schema, issue DROP TABLE before CREATE TABLE.

It could be that the sequence you are creating is the culprit. In PostgreSQL, sequences are implemented as a table with a particular set of columns. If you already have the sequence defined, you should probably skip creating it. Unfortunately, there's no equivalent in CREATE SEQUENCE to the IF NOT EXISTS construct available in CREATE TABLE. By the looks of it, you might be creating your schema unconditionally, anyways, so it's reasonable to use

DROP TABLE IF EXISTS csd_relationship;
DROP SEQUENCE IF EXISTS csd_relationship_csd_relationship_id_seq;

before the rest of your schema update; In case it isn't obvious, This will delete all of the data in the csd_relationship table, if there is any

import pandas as pd
df = pd.read_fwf('log.txt')
df.to_csv('log.csv')

You can use the below query to get a list of table names which uses the specific column in DB2:

SELECT TBNAME                
FROM SYSIBM.SYSCOLUMNS       
WHERE NAME LIKE '%COLUMN_NAME'; 

Note : Here replace the COLUMN_NAME with the column name that you are searching for.

var array = new Array(); // or the shortcut: = []
array.push ( {"cool":"34.33","also cool":"45454"} );
array.push (  {"cool":"34.39","also cool":"45459"} );

Your variable is a javascript object {} not an array [].

You could do:

var o = {}; // or the longer form: = new Object()
o.SomeNewProperty = "something";
o["SomeNewProperty"] = "something";

and

var o = { SomeNewProperty: "something" };
var o2 = { "SomeNewProperty": "something" };

Later, you add those objects to your array: array.push (o, o2);

Also JSON is simply a string representation of a javascript object, thus:

var json = '{"cool":"34.33","alsocool":"45454"}'; // is JSON
var o = JSON.parse(json); // is a javascript object
json = JSON.stringify(o); // is JSON again

You will have to use a setTimeout so I see your issue as

I have a script that is generated by PHP, and so am not able to put it into two different functions

What prevents you from generating two functions in your script?

function fizz() {
    var a;
    a = 'buzz';
    // sleep x desired
    a = 'complete';
}

Could be rewritten as

function foo() {
    var a; // variable raised so shared across functions below
    function bar() { // consider this to be start of fizz
        a = 'buzz';
        setTimeout(baz, x); // start wait
    } // code split here for timeout break
    function baz() { // after wait
        a = 'complete';
    } // end of fizz
    bar(); // start it
}

You'll notice that a inside baz starts as buzz when it is invoked and at the end of invocation, a inside foo will be "complete".

Basically, wrap everything in a function, move all variables up into that wrapping function such that the contained functions inherit them. Then, every time you encounter wait NUMBER seconds you echo a setTimeout, end the function and start a new function to pick up where you left off.

Most of the answers on this page are outdated.
Here's an updated python version to search google and get all results href's:

import urllib.parse
import re
from selenium import webdriver
driver.get("https://google.com/")
q = driver.find_element_by_name('q')
q.send_keys("always look on the bright side of life monty python")
q.submit();
sleep(1)
links= driver.find_elements_by_xpath("//h3[@class='r']//a")
for link in links:
    url = urllib.parse.unquote(webElement.get_attribute("href")) # decode the url
    url = re.sub("^.*?(?:url\?q=)(.*?)&sa.*", r"\1", url, 0, re.IGNORECASE) # get the clean url

Please note that the element id/name/class (@class='r') ** will change depending on the user agent**.
The above code used PhantomJS default user agent.

The

standard A U Thor <[email protected]> format

Seems to be defined as followed: ( as far as i know, with absolutely no warranty )

A U Thor = required username

• The separation of the characters probably indicates that spaces are allowed, it could also be resembling initials.
• The username has to be followed by 1 space, extra spaces will be truncated

<[email protected]> = optional email address

• Must always be between < > signs.
• The email address format isn't validated, you can pretty much enter whatever you want
• Optional, you can omit this explicitly by using <>

If you don't use this exact syntax, git will search through the existing commits and use the first commit that contains your provided string.

Examples:

1. Only user name

   Omit the email address explicitly:

   git commit --author="John Doe <>" -m "Impersonation is evil."
   

2. Only email

   Technically this isn't possible. You can however enter the email address as the username and explicitly omit the email address. This doesn't seem like it's very useful. I think it would make even more sense to extract the user name from the email address and then use that as the username. But if you have to:

   git commit --author="[email protected] <>" -m "Impersonation is evil." 
   

I ran in to this when trying to convert a repository from mercurial to git. I tested the commands on msysgit 1.7.10.

For a colloquial name there is "splatting".

For arguments (list type) you use single * and for keyword arguments (dictionary type) you use double **.

Both * and ** is sometimes referred to as "splatting".

See for reference of this name being used: https://stackoverflow.com/a/47875892/14305096

Just a speculation, I have not enough experience to try it... )-:

Since GoogleMap is a fragment, it should be possible to catch marker onClick event and show custom fragment view. A map fragment will be still visible on the background. Does anybody tried it? Any reason why it could not work?

The disadvantage is that map fragment would be freezed on backgroud, until a custom info fragment return control to it.

Sort each element then look for duplicates. There's a built-in function for sorting so you do not need to import anything

public class Csv
{
    public static DataTable DataSetGet(string filename, string separatorChar, out List<string> errors)
    {
        errors = new List<string>();
        var table = new DataTable("StringLocalization");
        using (var sr = new StreamReader(filename, Encoding.Default))
        {
            string line;
            var i = 0;
            while (sr.Peek() >= 0)
            {
                try
                {
                    line = sr.ReadLine();
                    if (string.IsNullOrEmpty(line)) continue;
                    var values = line.Split(new[] {separatorChar}, StringSplitOptions.None);
                    var row = table.NewRow();
                    for (var colNum = 0; colNum < values.Length; colNum++)
                    {
                        var value = values[colNum];
                        if (i == 0)
                        {
                            table.Columns.Add(value, typeof (String));
                        }
                        else
                        {
                            row[table.Columns[colNum]] = value;
                        }
                    }
                    if (i != 0) table.Rows.Add(row);
                }
                catch(Exception ex)
                {
                    errors.Add(ex.Message);
                }
                i++;
            }
        }
        return table;
    }
}

To see all the branches with out using git branch -a you should execute:

for remote in `git branch -r`; do git branch --track $remote; done
git fetch --all
git pull --all

Now you can see all the branches:

git branch

To push all the branches try:

git push --all

I faced similar problems. The article that helped me solve similar issues is by MKyong and is here: ****https://www.mkyong.com/maven/how-to-install-maven-in-windows/**** It is very important to include in maven's path the file that contains the 'bin','boot', 'conf', 'lib' etc. file folders. For example, in my case, the correct path is: C:\Program Files\Apache Software Foundation\maven\apache-maven-3.5.0-bin\apache-maven-3.5.0

It depends what you wanted to do with that column e.g. here's an example of appending a new column to a recordset which can be updated on the client side:

Sub MSDataShape_AddNewCol()

  Dim rs As ADODB.Recordset
  Set rs = CreateObject("ADODB.Recordset")
  With rs
    .ActiveConnection = _
    "Provider=MSDataShape;" & _
    "Data Provider=Microsoft.Jet.OLEDB.4.0;" & _
    "Data Source=C:\Tempo\New_Jet_DB.mdb"
    .Source = _
    "SHAPE {" & _
    " SELECT ExistingField" & _
    " FROM ExistingTable" & _
    " ORDER BY ExistingField" & _
    "} APPEND NEW adNumeric(5, 4) AS NewField"

    .LockType = adLockBatchOptimistic

    .Open

    Dim i As Long
    For i = 0 To .RecordCount - 1
      .Fields("NewField").Value = Round(.Fields("ExistingField").Value, 4)
      .MoveNext
    Next

    rs.Save "C:\rs.xml", adPersistXML

  End With
End Sub

Probably it is too late but the below thing worked for me:

1. Open Settings --> this will open settings.json
2. type terminal.integrated.windows.shell
3. Click on {} at the top right corner -- this will open an editor where this setting can be over ridden.
4. Set the value as terminal.integrated.windows.shell: C:\\Users\\<user_name>\\Softwares\\Git\\bin\\bash.exe
5. Click Ctrl + S

Try to open new terminal. It should open in bash editor in integrated mode.

You've told jQuery to expect a JSONP response, which is why jQuery has added the callback=jQuery16406345664265099913_1319854793396&_=1319854793399 part to the URL (you can see this in your dump of the request).

What you're returning is JSON, not JSONP. Your response looks like

{"red" : "#f00"}

and jQuery is expecting something like this:

jQuery16406345664265099913_1319854793396({"red" : "#f00"})

If you actually need to use JSONP to get around the same origin policy, then the server serving colors.json needs to be able to actually return a JSONP response.

If the same origin policy isn't an issue for your application, then you just need to fix the dataType in your jQuery.ajax call to be json instead of jsonp.

The main benefit of "".equals(s) is you don't need the null check (equals will check its argument and return false if it's null), which you seem to not care about. If you're not worried about s being null (or are otherwise checking for it), I would definitely use s.isEmpty(); it shows exactly what you're checking, you care whether or not s is empty, not whether it equals the empty string

valid json string must have double quote.

JSON.parse({"u1":1000,"u2":1100})       // will be ok

no quote cause error

JSON.parse({u1:1000,u2:1100})    
// error Uncaught SyntaxError: Unexpected token u in JSON at position 2

single quote cause error

JSON.parse({'u1':1000,'u2':1100})    
// error Uncaught SyntaxError: Unexpected token u in JSON at position 2

You must valid json string at https://jsonlint.com

I struggled with the same problem. I have stored dates in SQL Server with format 'YYYY-MM-DD HH:NN:SS' for about 20 years, but today that was not able anymore from a C# solution using OleDbCommand and a UPDATE query.

The solution to my problem was to remove the hyphen - in the format, so the resulting formatting is now 'YYYYMMDD HH:MM:SS'. I have no idea why my previous formatting not works anymore, but I suspect there is something to do with some Windows updates for ADO.

var a = {"apples": 3, "oranges": 4, "bananas": 42};    

var array_keys = new Array();
var array_values = new Array();

for (var key in a) {
    array_keys.push(key);
    array_values.push(a[key]);
}

alert(array_keys);
alert(array_values);

For the complete list of attributes, the short answer is: no. The problem is that the attributes are actually defined as the arguments accepted by the getattr built-in function. As the user can reimplement __getattr__, suddenly allowing any kind of attribute, there is no possible generic way to generate that list. The dir function returns the keys in the __dict__ attribute, i.e. all the attributes accessible if the __getattr__ method is not reimplemented.

For the second question, it does not really make sense. Actually, methods are callable attributes, nothing more. You could though filter callable attributes, and, using the inspect module determine the class methods, methods or functions.

$(document).ready(function() {
 $('#main_search').val('hi');
});

is you want fix XSS on input element? you can encode string before output to input field

PHP:

$str = htmlentities($str);

C#:

str = WebUtility.HtmlEncode(str);

after that output value direct to input field:

<input type="text" value="<?php echo $str" />

This will give you the deadline :

select id,  
       title,
       created_at + interval '1' day * claim_window as deadline
from projects

Alternatively the function make_interval can be used:

select id,  
       title,
       created_at + make_interval(days => claim_window) as deadline
from projects

To get all projects where the deadline is over, use:

select *
from (
  select id, 
         created_at + interval '1' day * claim_window as deadline
  from projects
) t
where localtimestamp at time zone 'UTC' > deadline

Though I would give an update using the new composition api.

Component

<template>
  <div @mouseenter="hovering = true" @mouseleave="hovering = false">
    {{ hovering }}
  </div>
</template>

<script>
  import { ref } from '@vue/compsosition-api'

  export default {
    setup() {
      const hovering = ref(false)
      return { hovering }
    }
  })
</script>

Reusable Composition Function

Creating a useHover function will allow you to reuse in any components.

export function useHover(target: Ref<HTMLElement | null>) {
  const hovering = ref(false)

  const enterHandler = () => (hovering.value = true)
  const leaveHandler = () => (hovering.value = false)

  onMounted(() => {
    if (!target.value) return
    target.value.addEventListener('mouseenter', enterHandler)
    target.value.addEventListener('mouseleave', leaveHandler)
  })

  onUnmounted(() => {
    if (!target.value) return
    target.value.removeEventListener('mouseenter', enterHandler)
    target.value.removeEventListener('mouseleave', leaveHandler)
  })

  return hovering
}

Here's a quick example calling the function inside a Vue component.

<template>
  <div ref="hoverRef">
    {{ hovering }}
  </div>
</template>

<script lang="ts">
  import { ref } from '@vue/compsosition-api'
  import { useHover } from './useHover'

  export default {
    setup() {
      const hoverRef = ref(null)
      const hovering = useHover(hoverRef)
      return { hovering, hoverRef }
    }
  })
</script>

You can also use a library such as @vuehooks/core which comes with many useful functions including useHover.

So to start with some kind of answer : ) - You can't

I am not an expert, but as far as I understand DataFrames, they are not equal to rdd and DataFrame has no such thing as Partitioner.

Generally DataFrame's idea is to provide another level of abstraction that handles such problems itself. The queries on DataFrame are translated into logical plan that is further translated to operations on RDDs. The partitioning you suggested will probably be applied automatically or at least should be.

If you don't trust SparkSQL that it will provide some kind of optimal job, you can always transform DataFrame to RDD[Row] as suggested in of the comments.

Here's a procedure for Perl, just adapt it for C. Hope it helps.

• Open Notepad++
• Type F6 to open the execute window
• Write the following commands:
  • npp_save <-- Saves the current document
  • CD $(CURRENT_DIRECTORY) <-- Moves to the current directory
  • perl.exe -c -w "$(FILE_NAME)" <-- executes the command perl.exe -c -w , example: perl.exe -c -w test.pl (-c = compile -w = warnings)
• Click on Save
• Type a name to save the script (e.g. "Perl Compile")
• Go to Menu Plugins -> Nppexec -> advanced options -> Menu Item (Note: this is right BELOW 'Menu Items *')
• In the combobox titled 'Associated Script' select the script recently created in its dropdown menu, select Add/Modify and click OK -> OK
• Restart Notepad++
• Go to Settings -> Shortcut mapper -> Plugins -> search for the script name
• Select the shortcut to use (ie Ctrl + 1), click OK
• Verify that you can now run the script created with the shortcut selected.

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

This is mine, works on one default schema but it can be easily improved It gives 3 columnns with SQLQueries - Create / Drop / Rebuild (no reorganizing)

In Java, single quotes can only take one character, with escape if necessary. You need to use full quotation marks as follows for strings:

y = "hello";

You also used

System.out.println(g);

which I assume should be

System.out.println(y);

Note: When making char values (you'll likely use them later) you need single quotes. For example:

char foo='m';

I suggest to look at Dan Abramov (one of the React core maintainers) answer here:

I think you're making it more complicated than it needs to be.

function Example() {
  const [data, dataSet] = useState<any>(null)

  useEffect(() => {
    async function fetchMyAPI() {
      let response = await fetch('api/data')
      response = await response.json()
      dataSet(response)
    }

    fetchMyAPI()
  }, [])

  return <div>{JSON.stringify(data)}</div>
}

Longer term we'll discourage this pattern because it encourages race conditions. Such as — anything could happen between your call starts and ends, and you could have gotten new props. Instead, we'll recommend Suspense for data fetching which will look more like

const response = MyAPIResource.read();

and no effects. But in the meantime you can move the async stuff to a separate function and call it.

You can read more about experimental suspense here.

If you want to use functions outside with eslint.

 function OutsideUsageExample() {
  const [data, dataSet] = useState<any>(null)

  const fetchMyAPI = useCallback(async () => {
    let response = await fetch('api/data')
    response = await response.json()
    dataSet(response)
  }, [])

  useEffect(() => {
    fetchMyAPI()
  }, [fetchMyAPI])

  return (
    <div>
      <div>data: {JSON.stringify(data)}</div>
      <div>
        <button onClick={fetchMyAPI}>manual fetch</button>
      </div>
    </div>
  )
}

If you will use useCallback, look at example of how it works useCallback. Sandbox.

import React, { useState, useEffect, useCallback } from "react";

export default function App() {
  const [counter, setCounter] = useState(1);

  // if counter is changed, than fn will be updated with new counter value
  const fn = useCallback(() => {
    setCounter(counter + 1);
  }, [counter]);

  // if counter is changed, than fn will not be updated and counter will be always 1 inside fn
  /*const fnBad = useCallback(() => {
      setCounter(counter + 1);
    }, []);*/

  // if fn or counter is changed, than useEffect will rerun
  useEffect(() => {
    if (!(counter % 2)) return; // this will stop the loop if counter is not even

    fn();
  }, [fn, counter]);

  // this will be infinite loop because fn is always changing with new counter value
  /*useEffect(() => {
    fn();
  }, [fn]);*/

  return (
    <div>
      <div>Counter is {counter}</div>
      <button onClick={fn}>add +1 count</button>
    </div>
  );
}

Try this:

$(document).bind("contextmenu",function(e){
    return false;
});

I'm guessing your code failed BEFORE import sys, so it can't find it when you handle the exception.

Also, you should indent the your code whithin the try block.

try:

import sys
# .. other safe imports
try:
    import numpy as np
    # other unsafe imports
except ImportError:
    print "Error: missing one of the libraries (numpy, pyfits, scipy, matplotlib)"
    sys.exit()

It took me a while to combine everything, make it a bit secure, and have it work with Gmail. I hope this answer saves someone some time.

Create a file with the encrypted server password:

In Powershell, enter the following command (replace myPassword with your actual password):

"myPassword" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "C:\EmailPassword.txt"

Create a powershell script (Ex. sendEmail.ps1):

$User = "[email protected]"
$File = "C:\EmailPassword.txt"
$cred=New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, (Get-Content $File | ConvertTo-SecureString)
$EmailTo = "[email protected]"
$EmailFrom = "[email protected]"
$Subject = "Email Subject" 
$Body = "Email body text" 
$SMTPServer = "smtp.gmail.com" 
$filenameAndPath = "C:\fileIwantToSend.csv"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
$SMTPMessage.Attachments.Add($attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($cred.UserName, $cred.Password); 
$SMTPClient.Send($SMTPMessage)

Automate with Task Scheduler:

Create a batch file (Ex. emailFile.bat) with the following:

powershell -ExecutionPolicy ByPass -File C:\sendEmail.ps1

Create a task to run the batch file. Note: you must have the task run with the same user account that you used to encrypted the password! (Aka, probably the logged in user)

That's all; you now have a way to automate and schedule sending an email and an attachment with Windows Task Scheduler and Powershell. No 3rd party software and the password is not stored as plain text (though granted, not terribly secure either).

You can also read this article on the level of security this provides for your email password.

Try this:

dt.Rows[RowNumber]["ColumnName"] = "Your value"

For example: if you want to add value 5 (number 5) to 1st row and column name "index" you would do this

dt.Rows[0]["index"] = 5;

I believe DataTable row starts with 0

From Resetting SQL Server Identity Columns:

Retrieving the identity for the table Employees:

DBCC checkident ('Employees')

Repairing the identity seed (if for some reason the database is inserting duplicate identities):

DBCC checkident ('Employees', reseed)

Changing the identity seed for the table Employees to 1000:

DBCC checkident ('Employees', reseed, 1000)

The next row inserted will begin at 1001.

In case some one wants to know how to set up Environment variables

1. Click on the windows button on the bottom left and go to System
2. Click the Advanced System Settings link in the left column
3. In the System Properties window, click on the Advanced tab, then click the Environment Variables button near the bottom of that tab.
4. In the Environment Variables window , highlight the Path variable in the "System variables" section and click the Edit button. Add the path lines with the paths you want the computer to access.

Once you have done that you can run using the command from the start->command line as below

php <path to file location>

NOTE:

The method used in this answer (backticks) is deprecated in later versions of Python 2, and removed in Python 3. Use the str() function instead.

You can use :

string = 'string'
for i in range(11):
    string +=`i`
print string

It will print string012345678910.

To get string0, string1 ..... string10 you can use this as @YOU suggested

>>> string = "string"
>>> [string+`i` for i in range(11)]

Update as per Python3

You can use :

string = 'string'
for i in range(11):
    string +=str(i)
print string

It will print string012345678910.

To get string0, string1 ..... string10 you can use this as @YOU suggested

>>> string = "string"
>>> [string+str(i) for i in range(11)]

You should set your RecyclerView LayoutManager to Gridlayout mode. Just change your code when you want to set your RecyclerView LayoutManager:

I am using ImageMagick 6.6.9-7 on Ubuntu 12.04.
What worked for me was the following:

convert test.png -transparent white transparent.png

That changed all the white in the test.png to transparent.

Perhaps a more logical method would be to create a file (e.g. test.html), add some content and then try to set it as the index page:

DirectoryIndex test.html

For the most part, the .htaccess rule will override the Apache configuration where working at the directory/file level

Briefly, the error means that you can't use a static library to be linked w/ a dynamic one. The correct way is to have a libavcodec compiled into a .so instead of .a, so the other .so library you are trying to build will link well.

The shortest way to do so is to add --enable-shared at ./configure options. Or even you may try to disable shared (or static) libraries at all... you choose what is suitable for you!

The repository no longer supports self-signed certificates. You need to upgrade npm.

// Disable the certificate temporarily in order to do the upgrade
npm config set ca ""

// Upgrade npm. -g (global) means you need root permissions; be root 
// or prepend `sudo`
sudo npm install npm -g

// Undo the previous config change
npm config delete ca

// For Ubuntu/Debian-sid/Mint, node package is renamed to nodejs which 
// npm cannot find. Fix this:
sudo ln -s /usr/bin/nodejs /usr/bin/node

You need to open a new terminal session in order to use the updated npm.

Although the guidelines say "We welcome all constructive edits, but please make them substantial," the edit was rejected due to "This edit changes too much in the original post; the original meaning or intent of the post would be lost."

Probably your new domain contain / ? If so, try using separator other than / in sed, e.g. #, , etc.

find ./ -type f -exec sed -i 's#192.168.20.1#new.domain.com#' {} \;

It would also be good to enclose s/// in single quote rather than double quote to avoid variable substitution or any other unexpected behaviour

Try this:

CREATE FUNCTION dbo.FnDAYSADDNOWK(
          @addDate AS DATE, 
          @numDays AS INT
       ) RETURNS DATETIME AS

    BEGIN
    WHILE @numDays > 0 BEGIN
        SET @addDate = DATEADD(day, 1, @addDate)    
        IF DATENAME(DW, @addDate) <> 'sunday' BEGIN
            SET @numDays = @numDays - 1 
        END
    END

    RETURN CAST(@addDate AS DATETIME)
END

Actually only setTimeout is fine for that job and normally you cannot set exact delays with non determined methods as busy loops.

Create .bat file:

start javaw -jar %*

And choose app default to open .jar with this .bat file.

It will close cmd when start your .jar file.

So you have committed your local changes to your local repository. Then in order to get remote changes to your local repository without making changes to your local files, you can use git fetch. Actually git pull is a two step operation: a non-destructive git fetch followed by a git merge. See What is the difference between 'git pull' and 'git fetch'? for more discussion.

Detailed example:

Suppose your repository is like this (you've made changes test2:

* ed0bcb2 - (HEAD, master) test2
* 4942854 - (origin/master, origin/HEAD) first

And the origin repository is like this (someone else has committed test1):

* 5437ca5 - (HEAD, master) test1
* 4942854 - first

At this point of time, git will complain and ask you to pull first if you try to push your test2 to remote repository. If you want to see what test1 is without modifying your local repository, run this:

$ git fetch

Your result local repository would be like this:

* ed0bcb2 - (HEAD, master) test2 
| * 5437ca5 - (origin/master, origin/HEAD) test1 
|/  
* 4942854 - first 

Now you have the remote changes in another branch, and you keep your local files intact.

Then what's next? You can do a git merge, which will be the same effect as git pull (when combined with the previous git fetch), or, as I would prefer, do a git rebase origin/master to apply your change on top of origin/master, which gives you a cleaner history.

Copy a file from one location to another location means,need to copy the whole content to another location.Files.copy(Path source, Path target, CopyOption... options) throws IOException this method expects source location which is original file location and target location which is a new folder location with destination same type file(as original). Either Target location needs to exist in our system otherwise we need to create a folder location and then in that folder location we need to create a file with the same name as original filename.Then using copy function we can easily copy a file from one location to other.

 public static void main(String[] args) throws IOException {
                String destFolderPath = "D:/TestFile/abc";
                String fileName = "pqr.xlsx";
                String sourceFilePath= "D:/TestFile/xyz.xlsx";
                File f = new File(destFolderPath);
                if(f.mkdir()){
                    System.out.println("Directory created!!!!");
                }
                else {
                    System.out.println("Directory Exists!!!!");
                }
                f= new File(destFolderPath,fileName);
                if(f.createNewFile())   {

                    System.out.println("File Created!!!!");
                }   else {
                    System.out.println("File exists!!!!");
                }

                Files.copy(Paths.get(sourceFilePath), Paths.get(destFolderPath, fileName),REPLACE_EXISTING);
                System.out.println("Copy done!!!!!!!!!!!!!!");


            }

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

Another solution which is a bit cleaner - just specify a different work tree.

To checkout everything from your HEAD (not index) to a specific out directory:

git --work-tree=/path/to/outputdir checkout HEAD -- .

To checkout a subdirectory or file from your HEAD to a specific directory:

git --work-tree=/path/to/outputdir checkout HEAD -- subdirname

When you pass an object like this:

new SelectList(Model, "Code", "Name", 0)

you are saying: the Source (Model) and Key ("Code") the Text ("Name") and the selected value 0. You probably do not have a 0 value in your source for Code property, so the HTML Helper will select the first element to pass the real selectedValue to this control.

Here's my take if you want to try using multiprocesses to process each row of numpy array,

from multiprocessing import Pool
import numpy as np

def my_function(x):
    pass     # do something and return something

if __name__ == '__main__':    
    X = np.arange(6).reshape((3,2))
    pool = Pool(processes = 4)
    results = pool.map(my_function, map(lambda x: x, X))
    pool.close()
    pool.join()

pool.map take in a function and an iterable.
I used 'map' function to create an iterator over each rows of the array.
Maybe there's a better to create the iterable though.

I couldn't get it to work with a hardware device. I kept getting the same error, but...

For your emulator you have to choose the IntelX86 Atom System image. Then ADB will connect to your emulator and it will properly install the installDebug.apk.

This is what I had to do.

Also look at this tutorial. It helped me immensely.

It Work for me if i use ChangeDetectorRef in Angular 9

@ViewChild('search', {static: false})
public searchElementRef: ElementRef;

constructor(private changeDetector: ChangeDetectorRef) {}

//then call this when this.display = true;
show() {
   this.display = true;
   this.changeDetector.detectChanges();
}

There is also at least one library for doing native threading from within Node.js: node-webworker-threads

https://github.com/audreyt/node-webworker-threads

This basically implements the Web Worker browser API for node.js.

For SQL server 2012,

1. First, log in to the SQL server as an administrator and go to Security tab

2. Then move into Server Roles and double click on sysadmin role

3. Now add user which you want to give permission to create Database by clicking Add button

4. Click OK button and now run the query

Hope this will help for someone

Use DefinePlugin.

The DefinePlugin allows you to create global constants which can be configured at compile time.

new webpack.DefinePlugin(definitions)

Example:

plugins: [
  new webpack.DefinePlugin({
    PRODUCTION: JSON.stringify(true)
  })
  //...
]

Usage:

console.log(`Environment is in production: ${PRODUCTION}`);

You can assign this yourself very easily, here goes a step by step explaination.

1.) In you xCode .m file type the following, it does not matter where you type as long as it's an empty area.

/*
*/

2.)Highlight that two lines of code then drag and drop onto 'code snippet library panel' area (it's at the bottom part of Utilities panel). A light blue plus sign will show up if you do it right.

3.) After you let go of your mouse button, a new window will pop up and will ask you to add name, short cut etc; as shown. As you can see I added my shortcut to //. So every time I want a block comment I will type //. Hope this helps

This is a common question in C++ programming. There are two valid answers to this. There are advantages and disadvantages to both answers and your choice will depend on context. The common answer is to put all the implementation in the header file, but there's another approach will will be suitable in some cases. The choice is yours.

The code in a template is merely a 'pattern' known to the compiler. The compiler won't compile the constructors cola<float>::cola(...) and cola<string>::cola(...) until it is forced to do so. And we must ensure that this compilation happens for the constructors at least once in the entire compilation process, or we will get the 'undefined reference' error. (This applies to the other methods of cola<T> also.)

Understanding the problem

The problem is caused by the fact that main.cpp and cola.cpp will be compiled separately first. In main.cpp, the compiler will implicitly instantiate the template classes cola<float> and cola<string> because those particular instantiations are used in main.cpp. The bad news is that the implementations of those member functions are not in main.cpp, nor in any header file included in main.cpp, and therefore the compiler can't include complete versions of those functions in main.o. When compiling cola.cpp, the compiler won't compile those instantiations either, because there are no implicit or explicit instantiations of cola<float> or cola<string>. Remember, when compiling cola.cpp, the compiler has no clue which instantiations will be needed; and we can't expect it to compile for every type in order to ensure this problem never happens! (cola<int>, cola<char>, cola<ostream>, cola< cola<int> > ... and so on ...)

The two answers are:

• Tell the compiler, at the end of cola.cpp, which particular template classes will be required, forcing it to compile cola<float> and cola<string>.
• Put the implementation of the member functions in a header file that will be included every time any other 'translation unit' (such as main.cpp) uses the template class.

Answer 1: Explicitly instantiate the template, and its member definitions

At the end of cola.cpp, you should add lines explicitly instantiating all the relevant templates, such as

template class cola<float>;
template class cola<string>;

and you add the following two lines at the end of nodo_colaypila.cpp:

template class nodo_colaypila<float>;
template class nodo_colaypila<std :: string>;

This will ensure that, when the compiler is compiling cola.cpp that it will explicitly compile all the code for the cola<float> and cola<string> classes. Similarly, nodo_colaypila.cpp contains the implementations of the nodo_colaypila<...> classes.

In this approach, you should ensure that all the of the implementation is placed into one .cpp file (i.e. one translation unit) and that the explicit instantation is placed after the definition of all the functions (i.e. at the end of the file).

Answer 2: Copy the code into the relevant header file

The common answer is to move all the code from the implementation files cola.cpp and nodo_colaypila.cpp into cola.h and nodo_colaypila.h. In the long run, this is more flexible as it means you can use extra instantiations (e.g. cola<char>) without any more work. But it could mean the same functions are compiled many times, once in each translation unit. This is not a big problem, as the linker will correctly ignore the duplicate implementations. But it might slow down the compilation a little.

Summary

The default answer, used by the STL for example and in most of the code that any of us will write, is to put all the implementations in the header files. But in a more private project, you will have more knowledge and control of which particular template classes will be instantiated. In fact, this 'bug' might be seen as a feature, as it stops users of your code from accidentally using instantiations you have not tested for or planned for ("I know this works for cola<float> and cola<string>, if you want to use something else, tell me first and will can verify it works before enabling it.").

Finally, there are three other minor typos in the code in your question:

• You are missing an #endif at the end of nodo_colaypila.h
• in cola.h nodo_colaypila<T>* ult, pri; should be nodo_colaypila<T> *ult, *pri; - both are pointers.
• nodo_colaypila.cpp: The default parameter should be in the header file nodo_colaypila.h, not in this implementation file.

I got the same message. But it's not making any sense in my case. My issue is I used a "NotMapped" property by mistake. It probably only means an error of Linq syntax or model class in some cases. The error message seems misleading. The original meaning of this message is you can't call async on same dbcontext more than once in the same request.

[NotMapped]
public int PostId { get; set; }
public virtual Post Post { get; set; }

Even with openssl v1.1.0 I had some problems passing our proxy, e.g. s_client: HTTP CONNECT failed: 400 Bad Request That forced me to write a minimal Java-class to show the SSL-Handshake

    public static void main(String[] args) throws IOException, URISyntaxException {
    HttpHost proxy = new HttpHost("proxy.my.company", 8080);
    DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
    CloseableHttpClient httpclient = HttpClients.custom()
            .setRoutePlanner(routePlanner)
            .build();
    URI uri = new URIBuilder()
            .setScheme("https")
            .setHost("www.myhost.com")
            .build();
    HttpGet httpget = new HttpGet(uri);
    httpclient.execute(httpget);
}

With following dependency:

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
        <type>jar</type>
    </dependency>

you can run it with Java SSL Logging turned on

This should produce nice output like

trustStore provider is :
init truststore

adding as trusted cert:

A one-line bash script would be easy to do - replace *.avi with your filetype:

for i in *.avi; do ffmpeg -i "$i" -qscale 0 "$(basename "$i" .avi)".mov  ; done

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

i think i'd try with MAX something like this:

SELECT staff_id, max( date ) from owner.table group by staff_id

then link in your other columns:

select staff_id, site_id, pay_level, latest
from owner.table, 
(   SELECT staff_id, max( date ) latest from owner.table group by staff_id ) m
where m.staff_id = staff_id
and m.latest = date

you can use DateUtils class in org.apache.commons.lang3.time package

DateUtils.addMonths(new Date(),1);

[Quick Answer]

After try to solve this problem in my workspace I found a solution.

This error is because there are a problem with Metro using some combinations of NPM and Node version.

You have 2 alternatives:

• Alternative 1: Try to update or downgrade npm and node version.

• Alternative 2: Go to this file: \node_modules\metro-config\src\defaults\blacklist.js and change this code:

  var sharedBlacklist = [
    /node_modules[/\\]react[/\\]dist[/\\].*/,
    /website\/node_modules\/.*/,
    /heapCapture\/bundle\.js/,
    /.*\/__tests__\/.*/
  ];
  

  and change to this:

  var sharedBlacklist = [
    /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
    /website\/node_modules\/.*/,
    /heapCapture\/bundle\.js/,
    /.*\/__tests__\/.*/
  ];
  

  Please note that if you run an npm install or a yarn install you need to change the code again.

If you're inserting text from a database or such (which one usually do), convert all "<br />"'s to &vbCrLf. Works great for me :)

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Process p = Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug");

Here's a one-liner that doesn't use/require the new job to be in a file:

(crontab -l 2>/dev/null; echo "*/5 * * * * /path/to/job -with args") | crontab -

The 2>/dev/null is important so that you don't get the no crontab for username message that some *nixes produce if there are currently no crontab entries.

ng-model-options in AngularJS 1.3 (beta as of this writing) is documented to support {updateOn: 'blur'}. For earlier versions, something like the following worked for me:

myApp.directive('myForm', function() {
  return {
    require: 'form',
    link: function(scope, element, attrs, formController) {
      scope.validate = function(name) {
        formController[name].isInvalid
            = formController[name].$invalid;
      };
    }
  };
});

With a template like this:

<form name="myForm" novalidate="novalidate" data-my-form="">
<input type="email" name="eMail" required="required" ng-blur="validate('eMail')" />
<span ng-show="myForm.eMail.isInvalid">Please enter a valid e-mail address.</span>
<button type="submit">Submit Form</button>
</form>

import re
regex = ur"\[P\] (.+?) \[/P\]+?"
line = "President [P] Barack Obama [/P] met Microsoft founder [P] Bill Gates [/P], yesterday."
person = re.findall(regex, line)
print(person)

yields

['Barack Obama', 'Bill Gates']

The regex ur"[\u005B1P\u005D.+?\u005B\u002FP\u005D]+?" is exactly the same unicode as u'[[1P].+?[/P]]+?' except harder to read.

The first bracketed group [[1P] tells re that any of the characters in the list ['[', '1', 'P'] should match, and similarly with the second bracketed group [/P]].That's not what you want at all. So,

• Remove the outer enclosing square brackets. (Also remove the stray 1 in front of P.)
• To protect the literal brackets in [P], escape the brackets with a backslash: \[P\].
• To return only the words inside the tags, place grouping parentheses around .+?.

I was testing the Sparkle framework with CocoaPods.

Sadly, I put pod 'Sparkle', '~> 1.21' in the PodFile in the wrong place. I put it underneath Testing (for unit tests).

Once placed in correct spot in PodFile, everything's fine.
