Not that simple:

python -c "import os; os.putenv('MY_DATA','1233')"
$ echo $MY_DATA # <- empty

But:

python -c "import os; os.putenv('MY_DATA','123'); os.system('bash')"
$ echo $MY_DATA #<- 123

You can declare the books (on line 2) as an array:

title: any = 'List of books are represted in the bookstore';
books: any = []; 
constructor(private service:  AppService){
}

ngOnInit(){
  this.getBookDetails();
}

getBookDetails() {
    this.service.getBooks().subscribe(books => {
        this.books = books.json();
        console.log(this.books);
    });
}

This is similar to https://superuser.com/questions/477628/export-all-regular-expression-matches-in-textpad-or-notepad-as-a-list.

I hope you are trying to extract :
"Performance"
"Maintenance"
"System Stability"

Here is the way - Step 1/3: Open Search->Find->Replace Tab , select Regular Expression Radio button. Enter in Find what : (\"[a-zA-Z0-9\s]+\") and in Replace with : \n\1 and click Replace All buttton.

Step 2/3: After first step your keywords will be in next lines.(as shown in next image). Now go to Mark tab and enter the same regex expression in Find what: Field. Put check mark on Bookmark Line. Then Click Mark All.

Step 3/3 : Goto Search -> Bookmarks -> Remove unmarked lines.

So you have the final result as below

You can easily do this one. In each column you will get a class with the field name prefixed with mat-column, so the class will be like mat-column-yourFieldName. So for that you can set the style like following

.mat-column-yourFieldName {
    flex: none;
    width: 100px;
}

So we can give fixed width for column as per our requirement.

Hope this helps for someone.

Since 1.10 release, you can now add multiple tags at once on build:

docker build -t name1:tag1 -t name1:tag2 -t name2 .

I've also created a jsfiddle for you: https://jsfiddle.net/9acgLf8e/

The documentation says it best and includes an example, (highlighting mine).

android:weightSum

Defines the maximum weight sum. If unspecified, the sum is computed by adding the layout_weight of all of the children. This can be used for instance to give a single child 50% of the total available space by giving it a layout_weight of 0.5 and setting the weightSum to 1.0.

So to correct superM's example, suppose you have a LinearLayout with horizontal orientation that contains two ImageViews and a TextView with. You define the TextView to have a fixed size, and you'd like the two ImageViews to take up the remaining space equally.

To accomplish this, you would apply layout_weight 1 to each ImageView, none on the TextView, and a weightSum of 2.0 on the LinearLayout.

Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".

This is an old question, but it has no chosen answer, and I just solved this problem myself. Here's my solution:

1. Make sure you are set up to work with your Google API in the first place. See Google's list of prerequisites. I was working with Google My Business, so I also went through it's Get Started process.

2. In the OAuth 2.0 playground, Step 1 requires you to select which API you want to authenticate. Select or input as applicable for your case (in my case for Google My Business, I had to input https://www.googleapis.com/auth/plus.business.manage into the "Input your own scopes" input field). Note: this is the same as what's described in step 6 of the "Make a simple HTTP request" section of the Get Started guide.

3. Assuming successful authentication, you should get an "Access token" returned in the "Step 1's result" step in the OAuth playground. Copy this token to your clipboard.

4. Open Postman and open whichever collection you want as necessary.

5. In Postman, make sure "GET" is selected as the request type, and click on the "Authorization" tab below the request type drop-down.

6. In the Authorization "TYPE" dropdown menu, select "Bearer Token"

7. Paste your previously copied "Access Token" which you copied from the OAuth playground into the "Token" field which displays in Postman.

8. Almost there! To test if things work, put https://mybusiness.googleapis.com/v4/accounts/ into the main URL input bar in Postman and click the send button. You should get a JSON list of accounts back in the response that looks something like the following:

   
   {
       "accounts": [
           {
               "name": "accounts/REDACTED",
               "accountName": "REDACTED",
               "type": "PERSONAL",
               "state": {
                   "status": "UNVERIFIED"
               }
           },
           {
               "name": "accounts/REDACTED",
               "accountName": "REDACTED",
               "type": "LOCATION_GROUP",
               "role": "OWNER",
               "state": {
                   "status": "UNVERIFIED"
               },
               "permissionLevel": "OWNER_LEVEL"
           }
       ]
   }

Angular CLI 1.7 introduced ng update.

ng update

A new Angular CLI command to help simplify keeping your projects up to date with the latest versions. Packages can define logic which will be applied to your projects to ensure usage of latest features as well as making changes to reduce or eliminate the impact related to breaking changes.

Configuration information for ng update can be found here

1.7 to 6 update

CLI 1.7 does not support an automatic v6 update. Manually install @angular/cli via your package manager, then run the update migration schematic to finish the process.

npm install @angular/cli@^6.0.0
ng update @angular/cli --migrate-only --from=1

UPDATED 30/04/2017:

1.0 Update

You should now follow the Angular CLI migration guide

UPDATED 04/03/2017:

RC Update

You should follow the Angular CLI RC migration guide

UPDATED 20/02/2017:

Please be aware 1.0.0-beta.32 has breaking changes and has removed ng init and ng update

The pull request here states the following:

BREAKING CHANGE: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Update functionality will return to the CLI, until then manual updates of applications will need done.

The angular-cli CHANGELOG.md states the following:

BREAKING CHANGES - @angular/cli: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.

UPDATED 17/02/2017:

Angular-cli has now been added to the NPM @angular package. You should now replace the above command with the following -

Global package:

npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Local project package:

rm -rf node_modules dist # On Windows use rmdir /s /q node_modules dist
npm install --save-dev @angular/cli@latest
npm install
ng init

ORIGINAL ANSWER

You should follow the steps from the README.md on GitHub for updating angular via the angular-cli.

Here they are:

Updating angular-cli

To update angular-cli to a new version, you must update both the global package and your project's local package.

Global package:

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest

Local project package:

rm -rf node_modules dist tmp # On Windows use rmdir /s /q node_modules dist tmp
npm install --save-dev angular-cli@latest
npm install
ng init

Running ng init will check for changes in all the auto-generated files created by ng new and allow you to update yours. You are offered four choices for each changed file: y (overwrite), n (don't overwrite), d (show diff between your file and the updated file) and h (help).

Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after ng init finishes.

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

You can use this way either :

Add this line to your recyclerView xml view :

        android:nestedScrollingEnabled="false"

try it ,recyclerview will be smoothly scrolled with flexible height

hope this helped .

Just use this:

{{you_date_field|date:'Y-m-d'}}

This will show something like 2016-10-16. You can use the format as you want.

Laravel >= 5.3 method lists() is deprecated use pluck()

$items = Items::pluck('name', 'id');

{!! Form::select('items', $items, null, ['class' => 'some_css_class']) !!}

This will give you a select box with same select options as id numbers in DB

for example if you have this in your DB table:

id name
1  item1
2  item2
3  item3
4  item4

in select box it will be like this

<select>
<option value="1">item1</option>
<option value="2">item2</option>
<option value="3">item3</option>
<option value="4">item4</option>
</select>

I found out that pluck now returns a collection, and you need to add ->toArray() at the end of pluck...so like this: pluck('name', 'id')->toArray();

There is no easy or general way to do what you want because it is just your subjective opinion that these letters look loke the latin letters you want to convert to. They are actually separate letters with their own distinct names and sounds which just happen to superficially look like a latin letter.

If you want that conversion, you have to create your own translation table based on what latin letters you think the non-latin letters should be converted to.

(If you only want to remove diacritial marks, there are some answers in this thread: How do I remove diacritics (accents) from a string in .NET? However you describe a more general problem)

None of above works for godaddy server centOS 6, apache 2.4, php 5.6

Instead, you should

Install the mbstring PHP Extension with EasyApache

check if you already have it by, putty or ssh

php -m | grep mbstring

[if nothing, means missing mbstring]

Now you need to goto godaddy your account page,

click manager server,

open whm ----- search for apache,

open "easy apache 4"(my case)

Now you need customize currently installed packages,

by

click "customize" button on top line next to "currently installed package..."

search mbstring,

click on/off toggle next to it.

click next, next, .... privision..done.

Now you should have mbstring

by check again at putty(ssh)

php -m | grep mbstring [should see mbstring]

or you can find mbstring at phpinfo() page

I just wanted to update this for the latest cool stuff in Rails 4.2, you can now do this inside any of your config/**/*.rb files:

config.x.whatever.you.want = 42

...and this will be available in your app as:

Rails.configuration.x.whatever.you.want

See more here: http://guides.rubyonrails.org/configuring.html#custom-configuration

$('#userid').change(function(){
  //fire your ajax call  
});

$('#userid').val(10).change();

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

It's ok to pass an array - in fact it amounts to the same thing

String.format("%s %s", "hello", "world!");

is the same as

String.format("%s %s", new Object[] { "hello", "world!"});

It's just syntactic sugar - the compiler converts the first one into the second, since the underlying method is expecting an array for the vararg parameter.

See

• Varargs - J2SE 1.5 Documentation

The config file for scripts and programs is ~/.bashrc and the config file that gets loaded when you use Terminal is ~/.bash_login.

I think the best way is to just have everything in ~/.bashrc.

For your specific question just enter (this will overwrite any existing ~/.bashrc):

echo "alias blah=\"/usr/bin/blah\"" >>~/.bashrc

into the Terminal and a ~/.bashrc file will be created with your new alises. After that just edit the file to add new aliases, functions, settings etc.

Use this site: https://rawgit.com , it works for me as I don't have permission issue with the svg file.
Please pay attention that RawGit is not a service of github, as mentioned in Rawgit FAQ :

RawGit is not associated with GitHub in any way. Please don't contact GitHub asking for help with RawGit

Enter the url of svg you need, such as :

https://github.com/sel-fish/redis-experiments/blob/master/dat/memDistrib-jemalloc-4.0.3.svg

Then, you can get the url bellow which can be used to display:

https://cdn.rawgit.com/sel-fish/redis-experiments/master/dat/memDistrib-jemalloc-4.0.3.svg

In Swift3:
let fileUrl = Foundation.URL(string: filePath)

The logical OR '||' automatically short circuits if it meets a true condition once.

false || false || true || false = true, stops at second condition.

On the other hand, the logical AND '&&' automatically short circuits if it meets a false condition once.

false && true && true && true = false, stops at first condition.

 @foreach (var m in Model)
    {
      <img src="~/Images/@m.Url" style="overflow: hidden; position: relative; width:200px; height:200px;" />
    }

You can delete all the rows with this command.But remember one thing that once you run truncate command you cannot rollback it.

  truncate tableName;

I think what you want is something like:

=INDEX(B:B,MATCH(C2,A:A,0))  

I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B.

On Windows7 all the databases are referred by a number in the file named pg_database under C:\Program Files (x86)\PostgreSQL\8.2\data\global. Then you should search for the folder name by that number under C:\Program Files (x86)\PostgreSQL\8.2\data\base. That is the content of the database.

From help(print):

Help on built-in function print in module builtins:

print(...)
    print(value, ..., sep=' ', end='\n', file=sys.stdout)

    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file: a file-like object (stream); defaults to the current sys.stdout.
    sep:  string inserted between values, default a space.
    end:  string appended after the last value, default a newline.

You can use the end keyword:

>>> for i in range(1, 11):
...     print(i, end='')
... 
12345678910>>> 

Note that you'll have to print() the final newline yourself. BTW, you won't get "12345678910" in Python 2 with the trailing comma, you'll get 1 2 3 4 5 6 7 8 9 10 instead.

On client:

  axios.get('/api', {
      params: {
        foo: 'bar'
      }
    });

On server:

function get(req, res, next) {

  let param = req.query.foo
   .....
}

This worked for me:

In package.json

Changed "@angular-devkit/build-angular": "^0.800.0" --> "@angular-devkit/build-angular": "^0.10.0" Then:

To get all the dropdown values you can use List.

List<string> lstDropDownValues = new List<string>();
int iValuescount = driver.FindElement(By.Xpath("\html\....\select\option"))

for(int ivalue = 1;ivalue<=iValuescount;ivalue++)
 {
  string strValue = driver.FindElement(By.Xpath("\html\....\select\option["+ ivalue +"]"));
  lstDropDownValues.Add(strValue); 
 }

I'll try to give the benchmark of the three most common way (also mentioned above):

from timeit import repeat

setup = """
import numpy as np;
import random;
x = np.linspace(0,100);
lb, ub = np.sort([random.random() * 100, random.random() * 100]).tolist()
"""
stmts = 'x[(x > lb) * (x <= ub)]', 'x[(x > lb) & (x <= ub)]', 'x[np.logical_and(x > lb, x <= ub)]'

for _ in range(3):
    for stmt in stmts:
        t = min(repeat(stmt, setup, number=100_000))
        print('%.4f' % t, stmt)
    print()

result:

0.4808 x[(x > lb) * (x <= ub)]
0.4726 x[(x > lb) & (x <= ub)]
0.4904 x[np.logical_and(x > lb, x <= ub)]

0.4725 x[(x > lb) * (x <= ub)]
0.4806 x[(x > lb) & (x <= ub)]
0.5002 x[np.logical_and(x > lb, x <= ub)]

0.4781 x[(x > lb) * (x <= ub)]
0.4336 x[(x > lb) & (x <= ub)]
0.4974 x[np.logical_and(x > lb, x <= ub)]

But, * is not supported in Panda Series, and NumPy Array is faster than pandas data frame (arround 1000 times slower, see number):

from timeit import repeat

setup = """
import numpy as np;
import random;
import pandas as pd;
x = pd.DataFrame(np.linspace(0,100));
lb, ub = np.sort([random.random() * 100, random.random() * 100]).tolist()
"""
stmts = 'x[(x > lb) & (x <= ub)]', 'x[np.logical_and(x > lb, x <= ub)]'

for _ in range(3):
    for stmt in stmts:
        t = min(repeat(stmt, setup, number=100))
        print('%.4f' % t, stmt)
    print()

result:

0.1964 x[(x > lb) & (x <= ub)]
0.1992 x[np.logical_and(x > lb, x <= ub)]

0.2018 x[(x > lb) & (x <= ub)]
0.1838 x[np.logical_and(x > lb, x <= ub)]

0.1871 x[(x > lb) & (x <= ub)]
0.1883 x[np.logical_and(x > lb, x <= ub)]

Note: adding one line of code x = x.to_numpy() will need about 20 µs.

For those who prefer %timeit:

import numpy as np
import random
lb, ub = np.sort([random.random() * 100, random.random() * 100]).tolist()
lb, ub
x = pd.DataFrame(np.linspace(0,100))

def asterik(x):
    x = x.to_numpy()
    return x[(x > lb) * (x <= ub)]

def and_symbol(x):
    x = x.to_numpy()
    return x[(x > lb) & (x <= ub)]

def numpy_logical(x):
    x = x.to_numpy()
    return x[np.logical_and(x > lb, x <= ub)]

for i in range(3):
    %timeit asterik(x)
    %timeit and_symbol(x)
    %timeit numpy_logical(x)
    print('\n')

result:

23 µs ± 3.62 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)

You can bind the DropDownList in different ways by using List, Dictionary, Enum, DataSet DataTable.
Main you have to consider three thing while binding the datasource of a dropdown.

1. DataSource - Name of the dataset or datatable or your datasource
2. DataValueField - These field will be hidden
3. DataTextField - These field will be displayed on the dropdwon.

you can use following code to bind a dropdownlist to a datasource as a datatable:

  SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString);

    SqlCommand cmd = new SqlCommand("Select * from tblQuiz", con);

    SqlDataAdapter da = new SqlDataAdapter(cmd);

    DataTable dt=new DataTable();
    da.Fill(dt);

    DropDownList1.DataTextField = "QUIZ_Name";
    DropDownList1.DataValueField = "QUIZ_ID"

    DropDownList1.DataSource = dt;
    DropDownList1.DataBind();

if you want to process on selection of dropdownlist, then you have to change AutoPostBack="true" you can use SelectedIndexChanged event to write your code.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    string strQUIZ_ID=DropDownList1.SelectedValue;
    string strQUIZ_Name=DropDownList1.SelectedItem.Text;
    // Your code..............
}

You can use $.browser to detect the browser name. possible values are :

• webkit (as of jQuery 1.4)
• safari (deprecated)
• opera
• msie
• mozilla

or get a boolean flag: $.browser.msie will be true if the browser is MSIE.

as for the version number, if you are only interested in the major release number - you can use parseInt($.browser.version, 10). no need to parse the $.browser.version string yourself.

Anyway, The $.support property is available for detection of support for particular features rather than relying on $.browser.

Here is a solution using Microsoft's System.Text.Json library:

static string FormatJsonText(string jsonString)
{
    using var doc = JsonDocument.Parse(
        jsonString,
        new JsonDocumentOptions
        {
            AllowTrailingCommas = true
        }
    );
    MemoryStream memoryStream = new MemoryStream();
    using (
        var utf8JsonWriter = new Utf8JsonWriter(
            memoryStream,
            new JsonWriterOptions
            {
                Indented = true
            }
        )
    )
    {
        doc.WriteTo(utf8JsonWriter);
    }
    return new System.Text.UTF8Encoding()
        .GetString(memoryStream.ToArray());
}

ORA-00907: missing right parenthesis

This is one of several generic error messages which indicate our code contains one or more syntax errors. Sometimes it may mean we literally have omitted a right bracket; that's easy enough to verify if we're using an editor which has a match bracket capability (most text editors aimed at coders do). But often it means the compiler has come across a keyword out of context. Or perhaps it's a misspelled word, a space instead of an underscore or a missing comma.

Unfortunately the possible reasons why our code won't compile is virtually infinite and the compiler just isn't clever enough to distinguish them. So it hurls a generic, slightly cryptic, message like ORA-00907: missing right parenthesis and leaves it to us to spot the actual bloomer.

The posted script has several syntax errors. First I will discuss the error which triggers that ORA-0097 but you'll need to fix them all.

Foreign key constraints can be declared in line with the referencing column or at the table level after all the columns have been declared. These have different syntaxes; your scripts mix the two and that's why you get the ORA-00907.

In-line declaration doesn't have a comma and doesn't include the referencing column name.

CREATE TABLE historys_T    (
    history_record    VARCHAR2 (8),
    customer_id       VARCHAR2 (8) 
          CONSTRAINT historys_T_FK FOREIGN KEY REFERENCES T_customers ON DELETE CASCADE,
    order_id           VARCHAR2 (10) NOT NULL,
          CONSTRAINT fk_order_id_orders REFERENCES orders ON DELETE CASCADE)

Table level constraints are a separate component, and so do have a comma and do mention the referencing column.

CREATE TABLE historys_T    (
    history_record    VARCHAR2 (8),
    customer_id       VARCHAR2 (8),    
    order_id           VARCHAR2 (10) NOT NULL,
    CONSTRAINT historys_T_FK FOREIGN KEY (customer_id) REFERENCES T_customers ON DELETE CASCADE,   
   CONSTRAINT fk_order_id_orders FOREIGN KEY (order_id) REFERENCES orders ON DELETE CASCADE)

Here is a list of other syntax errors:

1. The referenced table (and the referenced primary key or unique constraint) must already exist before we can create a foreign key against them. So you cannot create a foreign key for HISTORYS_T before you have created the referenced ORDERS table.
2. You have misspelled the names of the referenced tables in some of the foreign key clauses (LIBRARY_T and FORMAT_T).
3. You need to provide an expression in the DEFAULT clause. For DATE columns that is usually the current date, DATE DEFAULT sysdate.

Looking at our own code with a cool eye is a skill we all need to gain to be successful as developers. It really helps to be familiar with Oracle's documentation. A side-by-side comparison of your code and the examples in the SQL Reference would have helped you resolved these syntax errors in considerably less than two days. Find it here (11g) and here (12c).

As well as syntax errors, your scripts contain design mistakes. These are not failures, but bad practice which should not become habits.

1. You have not named most of your constraints. Oracle will give them a default name but it will be a horrible one, and makes the data dictionary harder to understand. Explicitly naming every constraint helps us navigate the physical database. It also leads to more comprehensible error messages when our SQL trips a constraint violation.
2. Name your constraints consistently. HISTORY_T has constraints called historys_T_FK and fk_order_id_orders, neither of which is helpful. A useful convention is <child_table>_<parent_table>_fk. So history_customer_fk and history_order_fk respectively.
3. It can be useful to create the constraints with separate statements. Creating tables then primary keys then foreign keys will avoid the problems with dependency ordering identified above.
4. You are trying to create cyclic foreign keys between LIBRARY_T and FORMATS. You could do this by creating the constraints in separate statement but don't: you will have problems when inserting rows and even worse problems with deletions. You should reconsider your data model and find a way to model the relationship between the two tables so that one is the parent and the other the child. Or perhaps you need a different kind of relationship, such as an intersection table.
5. Avoid blank lines in your scripts. Some tools will handle them but some will not. We can configure SQL*Plus to handle them but it's better to avoid the need.
6. The naming convention of LIBRARY_T is ugly. Try to find a more expressive name which doesn't require a needless suffix to avoid a keyword clash.
7. T_CUSTOMERS is even uglier, being both inconsistent with your other tables and completely unnecessary, as customers is not a keyword.

Naming things is hard. You wouldn't believe the wrangles I've had about table names over the years. The most important thing is consistency. If I look at a data dictionary and see tables called T_CUSTOMERS and LIBRARY_T my first response would be confusion. Why are these tables named with different conventions? What conceptual difference does this express? So, please, decide on a naming convention and stick to. Make your table names either all singular or all plural. Avoid prefixes and suffixes as much as possible; we already know it's a table, we don't need a T_ or a _TAB.

I came up with this.This seems to work best for me.It converts a string of number and splits it into array of integer:

void splitInput(int arr[], int sizeArr, char num[])
{
    for(int i = 0; i < sizeArr; i++)
        // We are subtracting 48 because the numbers in ASCII starts at 48.
        arr[i] = (int)num[i] - 48;
}

The direct children is

$('> .child-class', this)

You can write a generic filterByIndex() function and make use of type inference in TS to save the hassle with the callback function:

let's say you have your array [1,2,3,4] that you want to filter() with the indices specified in the [2,4] array.

var filtered = [1,2,3,4,].filter(byIndex(element => element, [2,4]))

the byIndex function expects the element function and an array and looks like this:

byIndex = (getter: (e:number) => number, arr: number[]) => (x: number) => {
    var i = getter(x);
    return arr.indexOf(i); 
}

result is then

filtered = [1,3]

By default, redo in Emacs requires pressing C-g, then undo.

However it's possible use Emacs built-in undo to implement a redo command too.

The package undo-fu, uses Emacs built-in undo functionality to expose both undo and redo.

Here we Go!

public static int getRandomInt(int lower, int upper) {
    if(lower > upper) return 0;
    if(lower == upper) return lower;
    int difference = upper - lower;
    int start = getRandomInt();

    //nonneg int in the range 0..difference - 1
    start = Math.abs(start) % (difference+1);

    start += lower;
    return start;
}

public static void main(String[] args){

    List<Integer> a= new ArrayList();

    int i;
    int c=0;
    for(;;) {
        c++;
        i= getRandomInt(100, 500000);
        if(!(a.contains(i))) {
            a.add(i);
            if (c == 10000) break;
            System.out.println(i);
        }


    }

    for(int rand : a) {
        System.out.println(rand);
    }



}

Get Random number Returns a random integer x satisfying lower <= x <= upper. If lower > upper, returns 0. @param lower @param upper @return

In the main method I created list then i check if the random number exist on the list if it doesn't exist i will add the random number to the list

I would add for Debian you need at least one compiler in the system (according to Debian Stretch and Jessie 32-bit libraries ).

I installed apt-get install -y gcc-multilib in order to run 32-bit executable file in my docker container based on debian:jessie.

The following syntax will escape you ONLY ONE quotation mark:

SELECT ''''

The result will be a single quote. Might be very helpful for creating dynamic SQL :).

All cookies are client and server

There is no difference. A regular cookie can be set server side or client side. The 'classic' cookie will be sent back with each request. A cookie that is set by the server, will be sent to the client in a response. The server only sends the cookie when it is explicitly set or changed, while the client sends the cookie on each request.

But essentially it's the same cookie.

But, behavior can change

A cookie is basically a name=value pair, but after the value can be a bunch of semi-colon separated attributes that affect the behavior of the cookie if it is so implemented by the client (or server). Those attributes can be about lifetime, context and various security settings.

HTTP-only (is not server-only)

One of those attributes can be set by a server to indicate that it's an HTTP-only cookie. This means that the cookie is still sent back and forth, but it won't be available in JavaScript. Do note, though, that the cookie is still there! It's only a built in protection in the browser, but if somebody would use a ridiculously old browser like IE5, or some custom client, they can actually read the cookie!

So it seems like there are 'server cookies', but there are actually not. Those cookies are still sent to the client. On the client there is no way to prevent a cookie from being sent to the server.

Alternatives to achieve 'only-ness'

If you want to store a value only on the server, or only on the client, then you'd need some other kind of storage, like a file or database on the server, or Local Storage on the client.

This is what I do when I need Initialized Global Constants:
1. Add a module called Globals
2. Add Properties like this into the Globals module:

Property Get PSIStartRow() As Integer  
    PSIStartRow = Sheets("FOB Prices").Range("F1").Value  
End Property  
Property Get PSIStartCell() As String  
    PSIStartCell = "B" & PSIStartRow  
End Property

select to_char(actual_start_date,'DD-MON-YYYY hh24:mi:ss') start_time,
to_char(actual_completion_date,'DD-MON-YYYY hh24:mi:ss') end_time,
floor((actual_completion_date-actual_start_date)*24*60)||'.'||round(mod((actual_completion_date-actual_start_date)*24*60*60,60)) diff_time
from fnd_concurrent_requests 
order by request_id desc;  

PuTTY can't find where your X server is, because you didn't tell it. (ssh on Linux doesn't have this problem because it runs under X so it just uses that one.) Fill in the blank box after "X display location" with your Xming server's address.

Alternatively, try MobaXterm. It has an X server builtin.

Try this:

Public Enum iSide
iBefore
iAfter

I suggest you look at the article called "Short Introduction to log4j". It contains a short explanation of log levels and demonstrates how they can be used in practice. The basic idea of log levels is that you want to be able to configure how much detail the logs contain depending on the situation. For example, if you are trying to troubleshoot an issue, you would want the logs to be very verbose. In production, you might only want to see warnings and errors.

The log level for each component of your system is usually controlled through a parameter in a configuration file, so it's easy to change. Your code would contain various logging statements with different levels. When responding to an Exception, you might call Logger.error. If you want to print the value of a variable at any given point, you might call Logger.debug. This combination of a configurable logging level and logging statements within your program allow you full control over how your application will log its activity.

In the case of log4j at least, the ordering of log levels is:

DEBUG < INFO < WARN < ERROR < FATAL

Here is a short example from that article demonstrating how log levels work.

   // get a logger instance named "com.foo"
   Logger logger = Logger.getLogger("com.foo");

   // Now set its level. Normally you do not need to set the
   // level of a logger programmatically. This is usually done
   // in configuration files.
   logger.setLevel(Level.INFO);

   Logger barlogger = Logger.getLogger("com.foo.Bar");

   // This request is enabled, because WARN >= INFO.
   logger.warn("Low fuel level.");

   // This request is disabled, because DEBUG < INFO.
   logger.debug("Starting search for nearest gas station.");

   // The logger instance barlogger, named "com.foo.Bar",
   // will inherit its level from the logger named
   // "com.foo" Thus, the following request is enabled
   // because INFO >= INFO.
   barlogger.info("Located nearest gas station.");

   // This request is disabled, because DEBUG < INFO.
   barlogger.debug("Exiting gas station search");

Although jQuery Maphilight plugin does the job, it relies on the outdated verbose imagemap in your html. I would prefer to keep the mapcoordinates external. This could be as JS with the jquery imagemap plugin but it lacks hover states. A nice solution is googles geomap visualisation in flash and JS. But the opensource future for this kind of vectordata however is svg, considering svg support accross all modern browsers, and googles svgweb for a flash convert for IE, why not a jquery plugin to add links and hoverstates to a svg map, like the JS demo here? That way you also avoid the complex step of transforming a vectormap to a imagemap coordinates.

In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325

Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.

Make sure that you have checked it to work properly with the IE version you specify.

It's not recommended to update the server configuration like server.xml or ROOT.xml.

You can put a context.xml configuration file under your web-application META-INF directory, with the context path setting included. This will override the default server setting?

i.e.:

<Context docBase="yourAppName" path="/yourAppPath" reloadable="true">

Take a look at String.format. Note, however, that it takes format specifiers similar to those of C's printf family of functions -- for example:

String.format("Hello %s, %d", "world", 42);

Would return "Hello world, 42". You may find this helpful when learning about the format specifiers. Andy Thomas-Cramer was kind enough to leave this link in a comment below, which appears to point to the official spec. The most commonly used ones are:

• %s - insert a string
• %d - insert a signed integer (decimal)
• %f - insert a real number, standard notation

This is radically different from C#, which uses positional references with an optional format specifier. That means that you can't do things like:

String.format("The {0} is repeated again: {0}", "word");

... without actually repeating the parameter passed to printf/format. (see The Scrum Meister's comment below)

If you just want to print the result directly, you may find System.out.printf (PrintStream.printf) to your liking.

Use the display property in CSS:

<body> 
    <div id="invisible" style="display:none;">Invisible DIV</div>  
    <div>Another DIV 
        <button onclick="document.getElementById('invisible').style.display='block'">
            Button
        </button>  
    </div>  
</body>

When the the display of the first div is set back to block it will appear and shift the second div down.

JavaScript does not have associative arrays. It has objects.

The following lines of code all do exactly the same thing - set the 'name' field on an object to 'orion'.

var f = new Object(); f.name = 'orion';
var f = new Object(); f['name'] = 'orion';
var f = new Array(); f.name = 'orion';
var f = new Array(); f['name'] = 'orion';
var f = new XMLHttpRequest(); f['name'] = 'orion';

It looks like you have an associative array because an Array is also an Object - however you're not actually adding things into the array at all; you're setting fields on the object.

Now that that is cleared up, here is a working solution to your example:

var text = '{ name = oscar }'
var dict = new Object();

// Remove {} and spaces
var cleaned = text.replace(/[{} ]/g, '');

// Split into key and value
var kvp = cleaned.split('=');

// Put in the object
dict[ kvp[0] ] = kvp[1];
alert( dict.name ); // Prints oscar.

SparkSQl support writing programs using Dataset and Dataframe API, along with it need to support sql.

In order to support Sql on DataFrames, first it requires a table definition with column names are required, along with if it creates tables the hive metastore will get lot unnecessary tables, because Spark-Sql natively resides on hive. So it will create a temporary view, which temporarily available in hive for time being and used as any other hive table, once the Spark Context stop it will be removed.

In order to create the view, developer need an utility called createOrReplaceTempView

Well, I get the attr rows from the table and get the length for that collection:

$("#myTable").attr('rows').length;

I think that jQuery works less.

Does the server actually get the requests, and are you handling the host name (alias) properly?

after adding to my .hosts file

Check your webserver log, to see how the request came in...

curl has options to dump the request sent, and response received, it is called trace, which will will be saved to a file.

--trace

If you are missing host or header information - you can force those headers with the config option.

I would get the curl request working on the command line, and then try to implement in PHP.

the config option is

-K/--config

the options that are relevant in curl are here

--trace Enables a full trace dump of all incoming and outgoing data, including descriptive information, to the given output file. Use "-" as filename to have the output sent to stdout.

      This option overrides previous uses of -v/--verbose or --trace-ascii.

      If this option is used several times, the last one will be used.

-K/--config Specify which config file to read curl arguments from. The config file is a text file in which command line arguments can be written which then will be used as if they were written on the actual command line. Options and their parameters must be specified on the same config file line, separated by whitespace, colon, the equals sign or any combination thereof (however, the preferred separa- tor is the equals sign). If the parameter is to contain whitespace, the parameter must be enclosed within quotes. Within double quotes, the following escape sequences are available: \, \", \t, \n, \r and \v. A backslash preceding any other letter is ignored. If the first column of a config line is a '#' character, the rest of the line will be treated as a comment. Only write one option per physical line in the config file.

      Specify the filename to -K/--config as '-' to make curl read the file from stdin.

      Note that to be able to specify a URL in the config file, you need to specify it using the --url option, and not by simply writing the URL on its own line. So, it could look similar to this:

      url = "http://curl.haxx.se/docs/"

      Long option names can optionally be given in the config file without the initial double dashes.

      When curl is invoked, it always (unless -q is used) checks for a default config file and uses it if found. The default config file is checked for in the following places in this order:

      1) curl tries to find the "home dir": It first checks for the CURL_HOME and then the HOME environment variables. Failing that, it uses getpwuid() on UNIX-like systems (which  returns  the  home  dir
      given the current user in your system). On Windows, it then checks for the APPDATA variable, or as a last resort the '%USERPROFILE%\Application Data'.

      2)  On windows, if there is no _curlrc file in the home dir, it checks for one in the same dir the curl executable is placed. On UNIX-like systems, it will simply try to load .curlrc from the deter-
      mined home dir.

      # --- Example file ---
      # this is a comment
      url = "curl.haxx.se"
      output = "curlhere.html"
      user-agent = "superagent/1.0"

      # and fetch another URL too
      url = "curl.haxx.se/docs/manpage.html"
      -O
      referer = "http://nowhereatall.com/"
      # --- End of example file ---

      This option can be used multiple times to load multiple config files.

from math import ceil

num = 0.1111111111000
num = ceil(num * 100) / 100.0

ORIGINAL ANSWER

I have rewritten your JS fiddle here: http://jsfiddle.net/YGQT9/

<div ng-app="myApp">

    <form name="saveTemplateData" action="#" ng-controller="FormCtrl" ng-submit="submitForm()">

        <br/><br/>

        <input type="submit">
    </form>
</div>

Here I'm using lots of angular directives(ng-controller, ng-model, ng-submit) where you were using basic html form submission. Normally all alternatives to "The angular way" work, but form submission is intercepted and cancelled by Angular to allow you to manipulate the data before submission

BUT the JSFiddle won't work properly as it doesn't allow any type of ajax/http post/get so you will have to run it locally.

For general advice on angular form submission see the cookbook examples

UPDATE The cookbook is gone. Instead have a look at the 1.x guide for for form submission

The cookbook for angular has lots of sample code which will help as the docs aren't very user friendly.

Angularjs changes your entire web development process, don't try doing things the way you are used to with JQuery or regular html/js, but for everything you do take a look around for some sample code, as there is almost always an angular alternative.

In addition to all the concerns expressed about why you give a rat's ass what the ID value is (all are correct that you shouldn't), let me add this to the mix:

If you've deleted all the records from the table, compacting the database will reset the seed value back to its original value.

For a table where there are still records, and you've inserted a value into the Autonumber field that is lower than the highest value, you have to use @Remou's method to reset the seed value. This also applies if you want to reset to the Max+1 in a table where records have been deleted, e.g., 300 records, last ID of 300, delete 201-300, compact won't reset the counter (you have to use @Remou's method -- this was not the case in earlier versions of Jet, and, indeed, in early versions of Jet 4, the first Jet version that allowed manipulating the seed value programatically).

please try db.collectionName.update({}, { $rename : { 'name.additional' : 'name.last' } }, { multi: true } )

and read this :) http://docs.mongodb.org/manual/reference/operator/rename/#_S_rename

I think its a bug, please apply the workaround and then try again: http://support.microsoft.com/kb/281517.

Also, go into Advanced tab, and confirm if Target columns length is Varchar(max).

/^$|\s+/ if this matched, there's whitespace or its empty.

Update 2018

Bootstrap 2.x

You could create a new CSS class such as:

.img-center {margin:0 auto;}

And then, add this to each IMG:

 <img src="images/2.png" class="img-responsive img-center">

OR, just override the .img-responsive if you're going to center all images..

 .img-responsive {margin:0 auto;}

Demo: http://bootply.com/86123

Bootstrap 3.x

EDIT - With the release of Bootstrap 3.0.1, the center-block class can now be used without any additional CSS..

 <img src="images/2.png" class="img-responsive center-block">

Bootstrap 4

In Bootstrap 4, the mx-auto class (auto x-axis margins) can be used to center images that are display:block. However, img is display:inline by default so text-center can be used on the parent.

<div class="container">
    <div class="row">
        <div class="col-12">
            <img class="mx-auto d-block" src="//placehold.it/200">  
        </div>
    </div>
    <div class="row">
        <div class="col-12 text-center">
            <img src="//placehold.it/200">  
        </div>
    </div>

Update (2016):

If you only need SOAP client, there is well maintained library called zeep. It supports both Python 2 and 3 :)

Update:

Additionally to what is mentioned above, I will refer to Python WebServices page which is always up-to-date with all actively maintained and recommended modules to SOAP and all other webservice types.

Unfortunately, at the moment, I don't think there is a "best" Python SOAP library. Each of the mainstream ones available has its own pros and cons.

Older libraries:

• SOAPy: Was the "best," but no longer maintained. Does not work on Python 2.5+

• ZSI: Very painful to use, and development is slow. Has a module called "SOAPpy", which is different than SOAPy (above).

"Newer" libraries:

• SUDS: Very Pythonic, and easy to create WSDL-consuming SOAP clients. Creating SOAP servers is a little bit more difficult. (This package does not work with Python3. For Python3 see SUDS-py3)

• SUDS-py3: The Python3 version of SUDS

• spyne: Creating servers is easy, creating clients a little bit more challenging. Documentation is somewhat lacking.

• ladon: Creating servers is much like in soaplib (using a decorator). Ladon exposes more interfaces than SOAP at the same time without extra user code needed.

• pysimplesoap: very lightweight but useful for both client and server - includes a web2py server integration that ships with web2py.

• SOAPpy: Distinct from the abandoned SOAPpy that's hosted at the ZSI link above, this version was actually maintained until 2011, now it seems to be abandoned too.
• soaplib: Easy to use python library for writing and calling soap web services. Webservices written with soaplib are simple, lightweight, work well with other SOAP implementations, and can be deployed as WSGI applications.

Of the above, I've only used SUDS personally, and I liked it a lot.

For this problem, I have finally put a new <i> tag to refresh the select instead. Don't try to trigger an event if the selected option is the same that the one already selected.

If user click on the "refresh" button, I trigger the onchange event of my select with :

const refreshEquipeEl = document.getElementById("refreshEquipe1");

function onClickRefreshEquipe(event){
    let event2 = new Event('change');
    equipesSelectEl.dispatchEvent(event2);
}
refreshEquipeEl.onclick = onClickRefreshEquipe;

This way, I don't need to try select the same option in my select.

@jh314 is correct. In AndroidManifest.xml,

 <application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"></application>

In style.xml

  <!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorAccent">@color/red</item>
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

the item name must be colorAccent,it decides the application's widgets default color.

But if you want to change the color in code,Maybe @aknay's answer is correct.

Euler path is a graph using every edge(NOTE) of the graph exactly once. Euler circuit is a euler path that returns to it starting point after covering all edges.

While hamilton path is a graph that covers all vertex(NOTE) exactly once. When this path returns to its starting point than this path is called hamilton circuit.

If the string you're pulling in happens to be a hex number such as E01, then Excel will translate it as 0 even if you use the CStr function, and even if you first deposit it in a String variable type. One way around the issue is to append ' to the beginning of the value.

For example, when pulling values out of a Word table, and bringing them to Excel:

strWr = "'" & WorksheetFunction.Clean(.cell(iRow, iCol).Range.Text)

It means not found.

It is usually defined like so:

static const size_t npos = -1;

It is better to compare to npos instead of -1 because the code is more legible.

You can revert your

rails g/generate controller/model/migration xxx

output by using:

 rails d/destroy controller/model/migration xxx

In the case where an optional, typed parameter is good enough, consider the following code which accomplishes the same without repeating the properties or defining an interface:

export class Track {
   public title: string;
   public artist: string;
   public lyrics: string;

   constructor(track?: Track) {
     Object.assign(this, track);
   }
}

Keep in mind this will assign all properties passed in track, eve if they're not defined on Track.

The backslash \ is the escape character for regular expressions. Therefore a double backslash would indeed mean a single, literal backslash.

\ (backslash) followed by any of [\^$.|?*+(){} escapes the special character to suppress its special meaning.

ref : http://www.regular-expressions.info/reference.html

The ^ (Caret - or Ascii Circumflex), produced by pressing shift + 6, does not appear to have an Ascii opposite, namely an Ascii Inverted Circumflex.

But for your alternative character pairing that also have keyboard combinations, you could use:

ˆ (Circumflex) shift + alt + i and
? (Caron) shift + alt + t

Here is another option: delete the builds with cURL.

$ curl -X POST http://jenkins-host.tld:8080/jenkins/job/myJob/[1-56]/doDeleteAll

The above deletes build #1 to #56 for job myJob.

If authentication is enabled on the Jenkins instance, a user name and API token must be provided like this:

$ curl -u userName:apiToken -X POST http://jenkins-host.tld:8080/jenkins/job/myJob/[1-56]/doDeleteAll

The API token must be fetched from the /me/configure page in Jenkins. Just click on the "Show API Token..." button to display both the user name and the API token.

Edit: one might have to replace doDeleteAll by doDelete in the URLs above to make this work, depending on the configuration or the version of Jenkins used.

There is another way to do it, using org.apache.commons.io.IOUtils to extract the String from the request

String jsonString = IOUtils.toString(request.getInputStream());

Then you can do whatever you want, convert it to JSON or other object with Gson, etc.

JSONObject json = new JSONObject(jsonString);
MyObject myObject = new Gson().fromJson(jsonString, MyObject.class);

Make sure HttpClient has access to the full client certificate (including the private key).

You are calling GetCert with a file "ClientCertificate.cer" which leads to the assumption that there is no private key contained - should rather be a pfx file within windows. It may be even better to access the certificate from the windows cert store and search it using the fingerprint.

Be careful when copying the fingerprint: There are some non-printable characters when viewing in cert management (copy the string over to notepad++ and check the length of the displayed string).

This is not actually a problem with the function being "void", but a problem with the function parameters. I think it's just g++ giving an unhelpful error message.

EDIT: As in the accepted answer, the fix is to use std::string instead of just string.

To solve this error, it is enough to add from google.colab import files in your code!

This is the most common issue faced by Windows users for running Docker Containers. IMO this is the "million dollar question on Docker"; @"Rocco Smit" has rightly pointed out "inbound traffic for it was disabled by default on my host machine's firewall"; in my case, my McAfee Anti Virus software. I added additional ports to be allowed for inbound traffic from other computers on the same Wifi LAN in the Firewall Settings of McAfee; then it was magic. I had struggled for more than a week browsing all over internet, SO, Docker documentations, Tutorials after Tutorials related to the Networking of Docker, and the many illustrations of "not supported on Windows" for "macvlan", "ipvlan", "user defined bridge" and even this same SO thread couple of times. I even started browsing google with "anybody using Docker in Production?", (yes I know Linux is more popular for Prod workloads compared to Windows servers) as I was not able to access (from my mobile in the same Home wifi) an nginx app deployed in Docker Container on Windows. After all, what good it is, if you cannot access the application (deployed on a Docker Container) from other computers / devices in the same LAN at-least; Ultimately in my case, the issue was just with a firewall blocking inbound traffic;

You need to somehow create a table with these values and then use NOT IN. This can be done with a temporary table, a CTE (Common Table Expression) or a Table Values Constructor (available in SQL-Server 2008):

SELECT email
FROM
    ( VALUES 
        ('email1')
      , ('email2')
      , ('email3')
    ) AS Checking (email)
WHERE email NOT IN 
      ( SELECT email 
        FROM Users
      ) 

The second result can be found with a LEFT JOIN or an EXISTS subquery:

SELECT email
     , CASE WHEN EXISTS ( SELECT * 
                          FROM Users u
                          WHERE u.email = Checking.email
                        ) 
            THEN 'Exists'
            ELSE 'Not exists'
       END AS status 
FROM
    ( VALUES 
        ('email1')
      , ('email2')
      , ('email3')
    ) AS Checking (email)

You can't do this with plain vanilla HTML, so JSF can't do much for you here as well.

If you're targeting decent browsers only, then just make use of CSS3:

.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

<label class="unselectable">Unselectable label</label>

If you'd like to cover older browsers as well, then consider this JavaScript fallback:

<!doctype html>
<html lang="en">
    <head>
        <title>SO question 2310734</title>
        <script>
            window.onload = function() {
                var labels = document.getElementsByTagName('label');
                for (var i = 0; i < labels.length; i++) {
                    disableSelection(labels[i]);
                }
            };
            function disableSelection(element) {
                if (typeof element.onselectstart != 'undefined') {
                    element.onselectstart = function() { return false; };
                } else if (typeof element.style.MozUserSelect != 'undefined') {
                    element.style.MozUserSelect = 'none';
                } else {
                    element.onmousedown = function() { return false; };
                }
            }
        </script>
    </head>
    <body>
        <label>Try to select this</label>
    </body>
</html>

If you're already using jQuery, then here's another example which adds a new function disableSelection() to jQuery so that you can use it anywhere in your jQuery code:

<!doctype html>
<html lang="en">
    <head>
        <title>SO question 2310734 with jQuery</title>
        <script src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script>
            $.fn.extend({ 
                disableSelection: function() { 
                    this.each(function() { 
                        if (typeof this.onselectstart != 'undefined') {
                            this.onselectstart = function() { return false; };
                        } else if (typeof this.style.MozUserSelect != 'undefined') {
                            this.style.MozUserSelect = 'none';
                        } else {
                            this.onmousedown = function() { return false; };
                        }
                    }); 
                } 
            });

            $(document).ready(function() {
                $('label').disableSelection();            
            });
        </script>
    </head>
    <body>
        <label>Try to select this</label>
    </body>
</html>

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

queue<int> q1, q2;
int i = 0;

void push(int v) {
  if( q1.empty() && q2.empty() ) {
     q1.push(v);
     i = 0;
  }
  else {
     if( i == 0 ) {
        while( !q1.empty() ) q2.push(q1.pop());
        q1.push(v);
        i = 1-i;
     }
     else {
        while( !q2.empty() ) q1.push(q2.pop());
        q2.push(v);
        i = 1-i;
     }
  }
}

int pop() {
   if( q1.empty() && q2.empty() ) return -1;
   if( i == 1 ) {
      if( !q1.empty() )
           return q1.pop();
      else if( !q2.empty() )
           return q2.pop();
   }
   else {
      if( !q2.empty() )
           return q2.pop();
      else if( !q1.empty() )
           return q1.pop();
   }
}

remove the ios::binary from your modes in your ofstream and use studentPassword.c_str() instead of (char *)&studentPassword in your write.write()

I'm sitting at a computer with none of the relevant bits of software, but from memory that code looks wrong. You're executing the command but discarding the RecordSet that objMyCommand.Execute returns.

I'd do:

Set objMyRecordset = objMyCommand.Execute

...and then lose the "open recordset" part.

You can set multiple background image in every view using custom method as below.

make plist for every theam with background image name and other color

#import <Foundation/Foundation.h>
@interface ThemeManager : NSObject
@property (nonatomic,strong) NSDictionary*styles;
+ (ThemeManager *)sharedManager;
-(void)selectTheme;
 @end

             #import "ThemeManager.h"

            @implementation ThemeManager
            @synthesize styles;
            + (ThemeManager *)sharedManager
            {
                static ThemeManager *sharedManager = nil;
                if (sharedManager == nil)
                {
                    sharedManager = [[ThemeManager alloc] init];
                }
                [sharedManager selectTheme];
                return sharedManager;
            }
            - (id)init
            {
                if ((self = [super init]))
                {

                }
                return self;
            }
            -(void)selectTheme{
                NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
                NSString *themeName = [defaults objectForKey:@"AppTheme"] ?: @"DefaultTheam";

                NSString *path = [[NSBundle mainBundle] pathForResource:themeName ofType:@"plist"];
                self.styles = [NSDictionary dictionaryWithContentsOfFile:path];
            }
            @end

Can use this via

 NSDictionary *styles = [ThemeManager sharedManager].styles;
 NSString *imageName = [styles objectForKey:@"backgroundImage"];
[imgViewBackGround setImage:[UIImage imageNamed:imageName]];

You can also use .split("[|]").

(I used this instead of .split("\\|"), which didn't work for me.)

@mani's response is now slightly outdated as using catch-all '*' routes is no longer supported when using Vue 3 onward. If this is no longer working for you, try replacing the old catch-all path with

{ path: '/:pathMatch(.*)*', component: PathNotFound },

Essentially, you should be able to replace the '*' path with '/:pathMatch(.*)*' and be good to go!

Reason: Vue Router doesn't use path-to-regexp anymore, instead it implements its own parsing system that allows route ranking and enables dynamic routing. Since we usually add one single catch-all route per project, there is no big benefit in supporting a special syntax for *.

(from https://next.router.vuejs.org/guide/migration/#removed-star-or-catch-all-routes)

Which Mac version are you using? try these paths

They are case insensitive, unless you do a binary comparison.

You can also use inspect.getdoc. It cleans up the __doc__ by normalizing tabs to spaces and left shifting the doc body to remove common leading spaces.

If you are able to use NOW() this would be simplest form:

SELECT * FROM `fab_scheduler` WHERE eventdate>=(NOW() - INTERVAL 1 DAY)) AND eventdate<NOW() ORDER BY eventdate DESC;

With MySQL 5.6+ query abowe should do. Depending on sql server, You may be required to use CURRDATE() instead of NOW() - which is alias for DATE(NOW()) and will return only date part of datetime data type;

You'd use REGEXP_REPLACE in order to remove all non-digit characters from a string:

select regexp_replace(column_name, '[^0-9]', '')
from mytable;

or

select regexp_replace(column_name, '[^[:digit:]]', '')
from mytable;

Of course you can write a function extract_number. It seems a bit like overkill though, to write a funtion that consists of only one function call itself.

create function extract_number(in_number varchar2) return varchar2 is
begin
  return regexp_replace(in_number, '[^[:digit:]]', '');
end; 

If you are using Windows,

1. make a folder and open git bash from there

2. in the git bash,

   git clone [email protected]:Example/projectName.git

That's the Unicode Replacement Character, \uFFFD. (info)

Something like this should work:

String strImport = "For some reason my ?double quotes? were lost.";
strImport = strImport.replaceAll("\uFFFD", "\"");

Works also for Java 1.8:

# in ~/.zshrc and ~/.bashrc

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home 
export PATH=$JAVA_HOME/bin:$PATH 

This fixed my issue on java 8.

As far as I know, it doesn't matter which one you use. They're equivalent in the eyes of the compiler. Use whichever one you prefer. I normally use class.

You can use the command PSGetSid from Microsoft's SysInternals team.

Download URL: http://technet.microsoft.com/en-gb/sysinternals/bb897417.aspx

Usage:

psgetsid [\\computer[,computer[,...] | @file] [-u username [-p password]]] [account|SID]
-u  Specifies optional user name for login to remote computer.
-p  Specifies optional password for user name. If you omit this you will be prompted to enter a hidden password.
Account PsGetSid will report the SID for the specified user account rather than the computer.
SID PsGetSid will report the account for the specified SID.
Computer    Direct PsGetSid to perform the command on the remote computer or computers specified. If you omit the computer name PsGetSid runs the command on the local system, and if you specify a wildcard (\\*), PsGetSid runs the command on all computers in the current domain.
@file   PsGetSid will execute the command on each of the computers listed in the file.

Example:

psgetsid S-1-5-21-583907252-682003330-839522115-63941

NB:

• Where the user is a domain/AD(LDAP) user, running this on any computer on the domain should give the same results.
• Where the user is local to the machine the command should either be run on that machine, or you should specify the computer via the optional parameter.

Update

If you use PowerShell, the following may be useful for resolving any AD users listed:

#create a drive for HKEY USERS:
New-PSDrive -PSProvider Registry -Name HKU -Root HKEY_USERS -ErrorAction SilentlyContinue

#List all immediate subfolders
#where they're a folder (not a key)
#and they's an SID (i.e. exclude .DEFAULT and SID_Classes entries)
#return the SID
#and return the related AD entry (should one exist).
Get-ChildItem -Path 'HKU:\' `
| ?{($_.PSIsContainer -eq $true) `
-and ($_.PSChildName -match '^S-[\d-]+$')} `
| select @{N='SID';E={$_.PSChildName}} `
, @{N='Name';E={Get-ADUser $_.PSChildName | select -expand Name}}

You could also refine the SID filter further to only pull back those SIDs which will resolve to an AD account if you wished; more on the SID structure here: https://technet.microsoft.com/en-us/library/cc962011.aspx

How to echo key and value of an array without and with loop

$keys = array_keys($page);
implode(',',$keys);
echo $keys[0].' is at '.$page['Home'];

You often will want to examine the particular properties of an instance of an object, without all of it's shared prototype methods and properties:

 Obj.prototype.toString= function(){
        var A= [];
        for(var p in this){
            if(this.hasOwnProperty(p)){
                A[A.length]= p+'='+this[p];
            }
        }

    return A.join(', ');
}

I created this directive that easily does that, truncates the string to a specified limit and adds a "show more/less" toggle. You can find it on GitHub: https://github.com/doukasd/AngularJS-Components

it can be used like this:

<p data-dd-collapse-text="100">{{veryLongText}}</p>

Here's the directive:

// a directive to auto-collapse long text
app.directive('ddCollapseText', ['$compile', function($compile) {
return {
    restrict: 'A',
    replace: true,
    link: function(scope, element, attrs) {

        // start collapsed
        scope.collapsed = false;

        // create the function to toggle the collapse
        scope.toggle = function() {
            scope.collapsed = !scope.collapsed;
        };

        // get the value of the dd-collapse-text attribute
        attrs.$observe('ddCollapseText', function(maxLength) {
            // get the contents of the element
            var text = element.text();

            if (text.length > maxLength) {
                // split the text in two parts, the first always showing
                var firstPart = String(text).substring(0, maxLength);
                var secondPart = String(text).substring(maxLength, text.length);

                // create some new html elements to hold the separate info
                var firstSpan = $compile('<span>' + firstPart + '</span>')(scope);
                var secondSpan = $compile('<span ng-if="collapsed">' + secondPart + '</span>')(scope);
                var moreIndicatorSpan = $compile('<span ng-if="!collapsed">...</span>')(scope);
                var toggleButton = $compile('<span class="collapse-text-toggle" ng-click="toggle()">{{collapsed ? "less" : "more"}}</span>')(scope);

                // remove the current contents of the element
                // and add the new ones we created
                element.empty();
                element.append(firstSpan);
                element.append(secondSpan);
                element.append(moreIndicatorSpan);
                element.append(toggleButton);
            }
        });
    }
};
}]);

And some CSS to go with it:

.collapse-text-toggle {
font-size: 0.9em;
color: #666666;
cursor: pointer;
}
.collapse-text-toggle:hover {
color: #222222;
}
.collapse-text-toggle:before {
content: '\00a0(';
}
.collapse-text-toggle:after {
content: ')';
}

Use console.debug("text");

You will see the logs inside the terminal.

Steps:

• Run the application:

react-native run-ios        # For iOS
react-native run-android    # For Android

• Run the logger:

react-native log-ios        # For iOS
react-native log-android    # For Android

While one liners are good for quick and dirty usage, I prefer below more verbose version for writing scripts. This is the template I use which takes care of many edge cases and allows you to write more complex code to execute on a folder. You can write your bash code in the function dir_command. Below, dir_coomand implements tagging each repository in git as an example. Rest of the script calls dir_command for each folder in directory. The example of iterating through only given set of folder is also include.

#!/bin/bash

#Use set -x if you want to echo each command while getting executed
#set -x

#Save current directory so we can restore it later
cur=$PWD
#Save command line arguments so functions can access it
args=("$@")

#Put your code in this function
#To access command line arguments use syntax ${args[1]} etc
function dir_command {
    #This example command implements doing git status for folder
    cd $1
    echo "$(tput setaf 2)$1$(tput sgr 0)"
    git tag -a ${args[0]} -m "${args[1]}"
    git push --tags
    cd ..
}

#This loop will go to each immediate child and execute dir_command
find . -maxdepth 1 -type d \( ! -name . \) | while read dir; do
   dir_command "$dir/"
done

#This example loop only loops through give set of folders    
declare -a dirs=("dir1" "dir2" "dir3")
for dir in "${dirs[@]}"; do
    dir_command "$dir/"
done

#Restore the folder
cd "$cur"

Use this:

li { color:blue; }
li:nth-child(odd) { color:green; }
li:nth-child(even) { color:red; }

There's var.is_a? Class (in your case: var.is_a? Integer); that might fit the bill. Or there's Integer(var), where it'll throw an exception if it can't parse it.

The solution by tewha works well if you are trying to change the color on a page, but I want to be able to change the color on every page. I made some small modifications so that it would work for all pages on a UINavigationController

NavigationDelegate.h

//This will change the color of the navigation bar
#import <Foundation/Foundation.h>
@interface NavigationDelegate : NSObject<UINavigationControllerDelegate> {
}
@end

NavigationDelegate.m

#import "NavigationDelegate.h"
@implementation NavigationDelegate

- (void)navigationController:(UINavigationController *)navigationController 
      willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
    CGRect frame = CGRectMake(0, 0, 200, 44);//TODO: Can we get the size of the text?
    UILabel* label = [[[UILabel alloc] initWithFrame:frame] autorelease];
    label.backgroundColor = [UIColor clearColor];
    label.font = [UIFont boldSystemFontOfSize:20.0];
    label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
    label.textAlignment = UITextAlignmentCenter;
    label.textColor = [UIColor yellowColor];
    //The two lines below are the only ones that have changed
    label.text=viewController.title;
    viewController.navigationItem.titleView = label;
}
@end

If by ID:

$('#datepicker').datepicker({
    format: 'dd/mm/yyyy'

});

If by Class:

$('.datepicker').datepicker({
    format: 'dd/mm/yyyy'

});

I have create another css file and add the following code Not all element are included

/* Flatten das boostrap */
.well, .navbar-inner, .popover, .btn, .tooltip, input, select, textarea, pre, .progress, .modal, .add-on, .alert, .table-bordered, .nav>.active>a, .dropdown-menu, .tooltip-inner, .badge, .label, .img-polaroid, .panel {
    -moz-box-shadow: none !important;
    -webkit-box-shadow: none !important;
    box-shadow: none !important;
    -webkit-border-radius: 0px !important;
    -moz-border-radius: 0px !important;
    border-radius: 0px !important;
    border-collapse: collapse !important;
    background-image: none !important;
}

It is a security risk to have max_allowed_packet at higher value, as an attacker can push bigger sized packets and crash the system.

So, Optimum Value of max_allowed_packet to be tuned and tested.

It is to better to change when required (using set global max_allowed_packet = xxx) than to have it as part of my.ini or my.conf.

Why this is not possible:

Because String and Integer are not in the same Object hierarchy.

      Object
     /      \
    /        \
String     Integer

The casting which you are trying, works only if they are in the same hierarchy, e.g.

      Object
     /
    /
   A
  /
 /
B

In this case, (A) objB or (Object) objB or (Object) objA will work.

Hence as others have mentioned already, to convert an integer to string use:

String.valueOf(integer), or Integer.toString(integer) for primitive,

or

Integer.toString() for the object.

SQLExplorer is a great Eclipse plugin or standalone interface that works with many different database systems, either with dedicated drivers or with ODBC.

First clear the temporary files in Windows system, then restart your system.

Run > %temp% > delete all files

The standard option grep -l (that is a lowercase L) could do this.

From the Unix standard:

-l
    (The letter ell.) Write only the names of files containing selected
    lines to standard output. Pathnames are written once per file searched.
    If the standard input is searched, a pathname of (standard input) will
    be written, in the POSIX locale. In other locales, standard input may be
    replaced by something more appropriate in those locales.

You also do not need -H in this case.

Based on luttken's answer. Thought I'd add my twist :)

function dateIsInBetween(\DateTime $from, \DateTime $to, \DateTime $subject)
{
    return $subject->getTimestamp() > $from->getTimestamp() && $subject->getTimestamp() < $to->getTimestamp() ? true : false;
}

$paymentDate       = new \DateTime('now');
$contractDateBegin = new \DateTime('01/01/2001');
$contractDateEnd   = new \DateTime('01/01/2016');

echo dateIsInBetween($contractDateBegin, $contractDateEnd, $paymentDate) ? "is between" : "NO GO!";

You can just run "Java VisualVM" which is located at jdk/bin/jvisualvm.exe

This will open a GUI, use the "File" menu -> "Load..." then choose your *.hprof file

That's it, you're done!

This is a simplified answer of how to run SQL query from Flask Shell

First, map your module (if your module/app is manage.py in the principal folder and you are in a UNIX Operating system), run:

export FLASK_APP=manage

Run Flask shell

flask shell

Import what we need::

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy(app)
from sqlalchemy import text

Run your query:

result = db.engine.execute(text("<sql here>").execution_options(autocommit=True))

This use the currently database connection which has the application.

I removed whole css under in head, which was loading colors and images for error/highlighting messages in page.And the website is working fine now.

use from configurations must be very very easy like this :

var config = new MiniConfig("setting.conf");

config.AddOrUpdate("port", "1580");

if (config.TryGet("port", out int port)) // if config exist
{
    Console.Write(port);
}

for more details see MiniConfig

From v2.0 many users are using path, but we can use either path or url. For example in django 2.1.1 mapping to functions through url can be done as follows

from django.contrib import admin
from django.urls import path

from django.contrib.auth import login
from posts.views import post_home
from django.conf.urls import url

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^posts/$', post_home, name='post_home'),

]

where posts is an application & post_home is a function in views.py

There are two method two remove index in mysql. First method is GUI. In this method you have to open GUI interface of MYSQL and then go to that database and then go to that particular table in which you want to remove index.

After that click on the structure option, Then you can see table structure and below you can see table indexes. You can remove indexes by clicking on drop option

Second method by

ALTER TABLE student_login_credentials DROP INDEX created_at;

here student_login_credentials is table name and created_at is column name

For store associative arrays you can use serialize:

$arr = array(
    'a' => 1,
    'b' => 2,
    'c' => 3
);

file_put_contents('stored-array.txt', serialize($arr));

And load using unserialize:

$arr = unserialize(file_get_contents('stored-array.txt'));

print_r($arr);

But if need creat dinamic .php files with array (for example config files), you can use var_export(..., true);, like this:

Save in file:

$arr = array(
    'a' => 1,
    'b' => 2,
    'c' => 3
);

$str = preg_replace('#,(\s+|)\)#', '$1)', var_export($arr, true));
$str = '<?php' . PHP_EOL . 'return ' . $str . ';';

file_put_contents('config.php', $str);

Get array values:

$arr = include 'config.php';

print_r($arr);

This Will work in Spring boot 2.0.3+ and Jackson 2.0+

import com.fasterxml.jackson.annotation.JsonInclude;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class ApiDTO
{
    // your class variable and 
    // methods
}

Here is a way to do it that works, but may not be best practise for any language really:

var x,y;
x='something';
y=1;
undefined === y || (x = y);

alternatively

undefined !== y && (x = y);

Worked great on CentOS 6.5

yum install bcmath

All my calls to bcmath functions started working right after an apache restart

service httpd restart

Sweet!

The VSCode plugin Vetur; used for VueJS applications was overriding the setting for me.

Setting vetur.format.options.tabSize to my preferred number of spaces made it work.

Use the CSS overflow property:

.noscroll {
  width: 150px;
  height: 150px;
  overflow: auto; /* Or hidden, or visible */
}

Here are some more examples:

• overflow-x, overflow-y tests
• The CSS Overflow Property

If you absolutely must use HTML to give your text color, you have to use the (deprecated) <font>-tag:

<h2><font color="#006699">Process Report</font></h2>

But otherwise, I strongly recommend you to do as rekire said: use CSS.

    //Example to define how to do :

    DataTable dt = new DataTable();   

    dt.Columns.Add("ID");
    dt.Columns.Add("FirstName");
    dt.Columns.Add("LastName");
    dt.Columns.Add("Address");
    dt.Columns.Add("City");
           //  The table structure is:
            //ID    FirstName   LastName    Address     City

       //Now we want to add a PhoneNo column after the LastName column. For this we use the                               
             //SetOrdinal function, as iin:
        dt.Columns.Add("PhoneNo").SetOrdinal(3);

            //3 is the position number and positions start from 0.`enter code here`

               //Now the table structure will be:
              // ID      FirstName   LastName    PhoneNo    Address     City

For that particular case you can use:

.detail_container > ul + h1{ 
    color: blue; 
}

But if you need that same selector on many cases, you should have a class for those, like BoltClock said.

Copy isn't useless if you imagine the use case to copy some values into an existing collection. I.e. you want to overwrite existing elements instead of inserting.

An example: a = [1,2,3,4,5] b = [2,2,2,2,3,3,3,3,3,4,4,4,] a.copy(b) = [1,2,3,4,5,3,3,3,3,4,4,4]

However I'd expect a copy method that would take additional parameters for the start index of the source and target collection, as well as a parameter for count.

See Java BUG 6350752

I've managed to achieve it with minimal effort (just as simple as with ASP.NET Core).

For that I use OWIN Startup.cs file and Microsoft.Owin.Security.Jwt library.

In order for the app to hit Startup.cs we need to amend Web.config:

<configuration>
  <appSettings>
    <add key="owin:AutomaticAppStartup" value="true" />
    ...

Here's how Startup.cs should look:

using MyApp.Helpers;
using Microsoft.IdentityModel.Tokens;
using Microsoft.Owin;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Jwt;
using Owin;

[assembly: OwinStartup(typeof(MyApp.App_Start.Startup))]

namespace MyApp.App_Start
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.UseJwtBearerAuthentication(
                new JwtBearerAuthenticationOptions
                {
                    AuthenticationMode = AuthenticationMode.Active,
                    TokenValidationParameters = new TokenValidationParameters()
                    {
                        ValidAudience = ConfigHelper.GetAudience(),
                        ValidIssuer = ConfigHelper.GetIssuer(),
                        IssuerSigningKey = ConfigHelper.GetSymmetricSecurityKey(),
                        ValidateLifetime = true,
                        ValidateIssuerSigningKey = true
                    }
                });
        }
    }
}

Many of you guys use ASP.NET Core nowadays, so as you can see it doesn't differ a lot from what we have there.

It really got me perplexed first, I was trying to implement custom providers, etc. But I didn't expect it to be so simple. OWIN just rocks!

Just one thing to mention - after I enabled OWIN Startup NSWag library stopped working for me (e.g. some of you might want to auto-generate typescript HTTP proxies for Angular app).

The solution was also very simple - I replaced NSWag with Swashbuckle and didn't have any further issues.

Ok, now sharing ConfigHelper code:

public class ConfigHelper
{
    public static string GetIssuer()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Issuer"];
        return result;
    }

    public static string GetAudience()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Audience"];
        return result;
    }

    public static SigningCredentials GetSigningCredentials()
    {
        var result = new SigningCredentials(GetSymmetricSecurityKey(), SecurityAlgorithms.HmacSha256);
        return result;
    }

    public static string GetSecurityKey()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["SecurityKey"];
        return result;
    }

    public static byte[] GetSymmetricSecurityKeyAsBytes()
    {
        var issuerSigningKey = GetSecurityKey();
        byte[] data = Encoding.UTF8.GetBytes(issuerSigningKey);
        return data;
    }

    public static SymmetricSecurityKey GetSymmetricSecurityKey()
    {
        byte[] data = GetSymmetricSecurityKeyAsBytes();
        var result = new SymmetricSecurityKey(data);
        return result;
    }

    public static string GetCorsOrigins()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["CorsOrigins"];
        return result;
    }
}

Another important aspect - I sent JWT Token via Authorization header, so typescript code looks for me as follows:

(the code below is generated by NSWag)

@Injectable()
export class TeamsServiceProxy {
    private http: HttpClient;
    private baseUrl: string;
    protected jsonParseReviver: ((key: string, value: any) => any) | undefined = undefined;

    constructor(@Inject(HttpClient) http: HttpClient, @Optional() @Inject(API_BASE_URL) baseUrl?: string) {
        this.http = http;
        this.baseUrl = baseUrl ? baseUrl : "https://localhost:44384";
    }

    add(input: TeamDto | null): Observable<boolean> {
        let url_ = this.baseUrl + "/api/Teams/Add";
        url_ = url_.replace(/[?&]$/, "");

        const content_ = JSON.stringify(input);

        let options_ : any = {
            body: content_,
            observe: "response",
            responseType: "blob",
            headers: new HttpHeaders({
                "Content-Type": "application/json", 
                "Accept": "application/json",
                "Authorization": "Bearer " + localStorage.getItem('token')
            })
        };

See headers part - "Authorization": "Bearer " + localStorage.getItem('token')

At our business we use database change scripts. When a script is run, it's name is stored in the database and won't run again, unless that row is removed. Scripts are named based on date, time and code branch, so controlled execution is possible.

Lots and lots of testing is done before the scripts are run in the live environment, so "oopsies" only happen, generally speaking, on development databases.

I would go with Ryan's answer if you really want to do this.

In general on a *nix environment, you always want to err on giving away as little permissions as possible.

9 times out of 10, 755 is the ideal permission for this - as the only user with the ability to modify the files will be the webserver. Change this to 775 with your ftp user in a group if you REALLY need to change this.

Since you're new to php by your own admission, here's a helpful link for improving the security of your upload service: move_uploaded_file

You should try using Type.IsAssignableFrom instead.

I had a similar issue , The function name i was using matched one of the inbuilt functions declared in one of the header files that i included in the program.Reading through the compiler error message will tell you the exact header file and function name.Changing the function name solved this issue for me

Please check the file "system/core/CodeIgniter.php". It is defined in const CI_VERSION = '3.1.10';

In order to find out what's wrong you can use gradle's signingReport command.

On mac:

./gradlew signingReport

On Windows:

gradlew signingReport

Ok, I finally wanted to have a pretty complete, searchable list of those variables for reference. Here is a complete (OCR-generated, as I did not easily find something akin to a printenv command) list of defined variables for a Visual C++ project on my machine. Probably not all macros are defined for others (e.g. OCTAVE_EXECUTABLE), but I wanted to err on the side of inclusiveness here.

Where to find this list within Visual Studio:

1. Open your C++ project's dialogue Property Pages
2. Select any textual field that can use a configuration variable. (in the screenshot, I use Target Name)
3. On the right side of the text box, click the small combobox button and select option <Edit...>.
4. In the new window (here, title is Target Name), click on button Macros>>.
5. Scroll through the giant list of environment/linker/macro variables.

Motivational screenshot:

You can use the IFNULL function inside the IF. This will be a little shorter, and there will be fewer repetitions of the field name.

SELECT IF(IFNULL(field1, '') = '', 'empty', field1) AS field1 
FROM tablename

This is a fundamental understanding in Java, but can be a little tricky to new programmers. Do a little research on the difference between a static and instance method. The basic difference is the instance method do() is only accessible to a instance of the class foo.

You must instantiate (create an instance of) the class, creating an object, that you use to call the instance method.

I have included your example with a couple comments and example.

public class SomeName {

//this is a static method and cannot call an instance method without a object
public static void main(String[] args){

    // can't do this from this static method, no object reference
    // someMethod();

    //create instance of object
    SomeName thisObj = new SomeName();
    //call instance method using object
    thisObj.someMethod();
}

//instance method
public void someMethod(){
    System.out.print("some message...");
}

}// end class SomeName

For example,

package main

import (
    "flag"
    "fmt"
    "os"
    "strconv"
)

func main() {
    flag.Parse()
    s := flag.Arg(0)
    // string to int
    i, err := strconv.Atoi(s)
    if err != nil {
        // handle error
        fmt.Println(err)
        os.Exit(2)
    }
    fmt.Println(s, i)
}

CursorAdapter Example with Sqlite

...
DatabaseHelper helper = new DatabaseHelper(this);
aListView = (ListView) findViewById(R.id.aListView);
Cursor c = helper.getAllContacts();
CustomAdapter adapter = new CustomAdapter(this, c);
aListView.setAdapter(adapter);
...

class CustomAdapter extends CursorAdapter {
    // CursorAdapter will handle all the moveToFirst(), getCount() logic for you :)

    public CustomAdapter(Context context, Cursor c) {
        super(context, c);
    }

    public void bindView(View view, Context context, Cursor cursor) {
        String id = cursor.getString(0);
        String name = cursor.getString(1);
        // Get all the values
        // Use it however you need to
        TextView textView = (TextView) view;
        textView.setText(name);
    }

    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        // Inflate your view here.
        TextView view = new TextView(context);
        return view;
    }
}

private final class DatabaseHelper extends SQLiteOpenHelper {

This doesn't quite match the OP requirements, though hopefully it helps. With Laravel you can define your rules in an easy-to-maintain format like so:

    $inputs = [
        'email'    => 'foo',
        'password' => 'bar',
    ];

    $rules = [
        'email'    => 'required|email',
        'password' => [
            'required',
            'string',
            'min:10',             // must be at least 10 characters in length
            'regex:/[a-z]/',      // must contain at least one lowercase letter
            'regex:/[A-Z]/',      // must contain at least one uppercase letter
            'regex:/[0-9]/',      // must contain at least one digit
            'regex:/[@$!%*#?&]/', // must contain a special character
        ],
    ];

    $validation = \Validator::make( $inputs, $rules );

    if ( $validation->fails() ) {
        print_r( $validation->errors()->all() );
    }

Would output:

    [
        'The email must be a valid email address.',
        'The password must be at least 10 characters.',
        'The password format is invalid.',
    ]

(The regex rules share an error message by default—i.e. four failing regex rules result in one error message)

Yes, bigger than 60x60 are supported. For simplicity, create icons of these 4 sizes:

1) 60x60  <= default
2) 76x76
3) 120x120
4) 152x152

Now, it's preferable to add them as links in your HTML as:

<link rel="apple-touch-icon" href="touch-icon-iphone.png">
<link rel="apple-touch-icon" sizes="76x76" href="touch-icon-ipad.png">
<link rel="apple-touch-icon" sizes="120x120" href="touch-icon-iphone-retina.png">
<link rel="apple-touch-icon" sizes="152x152" href="touch-icon-ipad-retina.png">

You can choose to not declare the 4 links above but just declare a single link, in which case give the highest size of 152x152 or even a size higher than that, say 196x196. It will always trim down the size for re-purposing. Ensure you mention the size.

You can also choose not to declare even a single link. Apple mentions that in this scenario, it will lookup the server root first for the size immediately higher that the size it wants (naming format: apple-touch-icon-<size>.png), and if that's not found then it will next look for the default file: apple-touch-icon.png. It's preferable that you define the link(s) as that will minimize the browser querying your server.

Icon necessities:

- use PNG, avoid interlaced
- use 24-bit PNG
- not necessary to use web-safe colors

In versions older than iOS 7, if you don't want it to add effects to your icons, then just add the suffix -precomposed.png to the file name. (iOS 7 doesn't add effects even without it).

Try this

public class Validation {

    public final static boolean isValidEmail(CharSequence target) {
        if (target == null) {
        return false;
        } else {
        return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
        }
    } 

    public static final boolean isValidPhoneNumber(CharSequence target) {
        if (target.length()!=10) {
            return false;
        } else {
            return android.util.Patterns.PHONE.matcher(target).matches();
        }
    }

}

A one-liner using tidyr's replace_na is

library(tidyr)
replace_na(mtcars,as.list(colMeans(mtcars,na.rm=T)))

If your df has columns that are non-numeric, this takes a little bit more work than a one-liner.

mean_to_fill <- select_if(ungroup(df), is.numeric) %>%
 colMeans(na.rm=T)

bind_cols(select(df, group1, group2, group3),
          select_if(ungroup(df), is.numeric) %>% 
            tidyr::replace_na(as.list(mean_to_fill))
          ) 

here is the solution for your query returning only one row for each date in that table here in the solution 'tony' will occur twice as two different start dates are there for it

SELECT * FROM 
(
    SELECT T1.*, ROW_NUMBER() OVER(PARTITION BY TRUNC(START_DATE),OWNER_NAME ORDER BY 1,2 DESC )  RNM
    FROM TABLE T1
)
WHERE RNM=1

This is discouraged (if you want to create/distribute a clean Docker image), since the PATH variable is set by /etc/profile script, the value can be overridden.

head /etc/profile:

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

At the end of the Dockerfile, you could add:

RUN echo "export PATH=$PATH" > /etc/environment

So PATH is set for all users.

I used HLOOKUP

A1 has a date; A2:A8 has forecasts captured at different times, I want the latest

=Hlookup(a1,a1:a8,count(a2:a8)+1)

This uses a standard hlookup formula with the lookup array defined by the number of entries.

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

echo Hello > \\.\pipe\PipeName

Solutions above didn't work. It simply displayed the last key/value pairs, but this did:

http://localhost/?key[]=1&key[]=2

Returns:

Array
(
[key] => Array
    (
        [0] => 1
        [1] => 2
    )

I have written an incredibly simple (5 lines of code) plugin for exactly this functionality:

http://byrichardpowell.github.com/jquery-or/

It allows you to effectively say "get this element, or if that element doesnt exist, use this element". For example:

$( '#doesntExist' ).or( '#exists' );

Whilst the accepted answer provides similar functionality to this, if both selectors (before & after the comma) exist, both selectors will be returned.

I hope it proves helpful to anyone who might land on this page via google.

For those use Msys/MinGW GIT, add this

Debugging PHP with VSCode using the vscode-php-debug extension

VSCode can now support debugging PHP projects through the marketplace extension vscode-php-debug.

This extension uses XDebug in the background, and allows you to use breakpoints, watches, stack traces and the like:

Installation is straightforward from within VSCode: Summon the command line with F1 and then type ext install php-debug

I solved this problem temporary by disabling the dfs permission.By adding below property code to conf/hdfs-site.xml

You can set picturebox's SizeMode property to PictureSizeMode.Zoom, this will increase the size of smaller images or decrease the size of larger images to fill the PictureBox

You should do this

    if (!image_array) {
      // image_array defined but not assigned automatically coerces to false
    } else if (!(0 in image_array)) {
      // empty array
      // doSomething
    }

During the installation you got a message Composer successfully installed to: ... this indicates where Composer was installed. But you might also search for the file composer.phar on your system.

Then simply:

1. Delete the file composer.phar.
2. Delete the Cache Folder:
   • Linux: /home/<user>/.composer
   • Windows: C:\Users\<username>\AppData\Roaming\Composer

That's it.

I was having this same problem using Angular CLI. I needed to import the bootstrap.js.min file in the .angular-cli.json file:

  "scripts": ["../node_modules/jquery/dist/jquery.min.js",
              "../node_modules/bootstrap/dist/js/bootstrap.min.js"],

Simple Steps:

Step 1: Click on Create new File

Step 2: Enter the folder name that you want, then press /

Step 3: Enter a sample file name. You must enter some text.

Step 4: Click Commit new file to create the folder

Step 5: Your folder is created!

In RSA crypto, when you generate a key pair, it's completely arbitrary which one you choose to be the public key, and which is the private key. If you encrypt with one, you can decrypt with the other - it works in both directions.

So, it's fairly simple to see how you can encrypt a message with the receiver's public key, so that the receiver can decrypt it with their private key.

A signature is proof that the signer has the private key that matches some public key. To do this, it would be enough to encrypt the message with that sender's private key, and include the encrypted version alongside the plaintext version. To verify the sender, decrypt the encrypted version, and check that it is the same as the plaintext.

Of course, this means that your message is not secret. Anyone can decrypt it, because the public key is well known. But when they do so, they have proved that the creator of the ciphertext has the corresponding private key.

However, this means doubling the size of your transmission - plaintext and ciphertext together (assuming you want people who aren't interested in verifying the signature, to read the message). So instead, typically a signature is created by creating a hash of the plaintext. It's important that fake hashes can't be created, so cryptographic hash algorithms such as SHA-2 are used.

So:

• To generate a signature, make a hash from the plaintext, encrypt it with your private key, include it alongside the plaintext.
• To verify a signature, make a hash from the plaintext, decrypt the signature with the sender's public key, check that both hashes are the same.

If an Activity calls onPause with a normal broadcast, receiving the Broadcast can be missed. A sticky broadcast can be checked after it was initiated in onResume.

Update 6/23/2020

Sticky broadcasts are deprecated.

See sendStickyBroadcast documentation.

This method was deprecated in API level 21.

Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that something has changed, with another mechanism for apps to retrieve the current value whenever desired.

Implement

Intent intent = new Intent("some.custom.action");
intent.putExtra("some_boolean", true);
sendStickyBroadcast(intent);

Resources

• Related post: What is the difference between sendStickyBroadcast and sendBroadcast in Android?

• See removeStickyBroadcast(Intent), and on API Level 5 +, isInitialStickyBroadcast() for usage in the Receiver's onReceive.

Ok I have found a solution. The problem is that the site uses SSLv3. And I know that there are some problems in the openssl module. Some time ago I had the same problem with the SSL versions.

<?php
function getSSLPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSLVERSION,3); 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

var_dump(getSSLPage("https://eresearch.fidelity.com/eresearch/evaluate/analystsOpinionsReport.jhtml?symbols=api"));
?>

When you set the SSL Version with curl to v3 then it works.

Edit:

Another problem under Windows is that you don't have access to the certificates. So put the root certificates directly to curl.

http://curl.haxx.se/docs/caextract.html

here you can download the root certificates.

curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/certs/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

Then you can use the CURLOPT_SSL_VERIFYPEER option with true otherwise you get an error.

I did the following and was able to connect:

1) changed IIS express config binding from local host to '*'

binding protocol="http" bindingInformation="*:8888:*"

2) Defined inbound rule on firewall to allow the particular port for the protocol type: tcp

3) Add the following command to add network configuration for your port: netsh http add urlacl url=http://*:8888/ user=everyone

    // default values
    url = url || 'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js';
    position = position || 0;

    // Check is jQuery exists
    if (!window.jQuery) {
        // Initialize <head>
        var head = document.getElementsByTagName('head')[0];
        // Create <script> element
        var script = document.createElement("script");
        // Append URL
        script.src = url;
        // Append type
        script.type = 'text/javascript';
        // Append script to <head>
        head.appendChild(script);
        // Move script on proper position
        head.insertBefore(script,head.childNodes[position]);

        script.onload = function(){
            if(typeof callback == 'function') {
                callback(jQuery);
            }
        };
    } else {
        if(typeof callback == 'function') {
            callback(jQuery);
        }
    }
}('https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js', 5, function($){ 
    console.log($);
}));

At GitHub is better explanation but generaly this function you can add anywhere in your HTML code and you will initialize jquery if is not already loaded.

Use the same process. You already have the variable iDiv which still refers to the original element <div id='block'> you've created. You just need to create another <div> and call appendChild().

// Your existing code unmodified...
var iDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';
document.getElementsByTagName('body')[0].appendChild(iDiv);

// Now create and append to iDiv
var innerDiv = document.createElement('div');
innerDiv.className = 'block-2';

// The variable iDiv is still good... Just append to it.
iDiv.appendChild(innerDiv);

http://jsfiddle.net/W4Sup/1/

The order of event creation doesn't have to be as I have it above. You can alternately append the new innerDiv to the outer div before you add both to the <body>.

var iDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';

// Create the inner div before appending to the body
var innerDiv = document.createElement('div');
innerDiv.className = 'block-2';

// The variable iDiv is still good... Just append to it.
iDiv.appendChild(innerDiv);

// Then append the whole thing onto the body
document.getElementsByTagName('body')[0].appendChild(iDiv);

try this

for i in *.png ; do mv "$i" "${i/remove_me*.png/.png}" ; done

Here is another way:

for file in Name*.png; do mv "$file" "01_$file"; done

if your terminal emulator doesn't have -hold you can sanitize a sourced script and hold the terminal with:

#!/bin/sh
sed "s/exit/return/g" script >/tmp/script
. /tmp/script
read

otherwise you can use $TERM -hold -e script

Are there other ways?

Negative margins were also used for horizontal (and vertical!) centering but there are quite a few drawbacks when you resize the window browser: no window slider; the content can't be seen anymore if the size of the window browser is too small.
No surprise as it uses absolute positioning, a beast never completely tamed!

Example: http://bluerobot.com/web/css/center2.html

So that was only FYI as you asked for it, margin: 0 auto; is a better solution.

The specification for 'mailto' body says:

The body of a message is simply lines of US-ASCII characters. The only two limitations on the body are as follows:

• CR and LF MUST only occur together as CRLF; they MUST NOT appear independently in the body.
• Lines of characters in the body MUST be limited to 998 characters, and SHOULD be limited to 78 characters, excluding the CRLF.

https://tools.ietf.org/html/rfc5322#section-2.3

Generally nowadays most email clients are good at autolinking, but not all do, due to security concerns. You can likely find some work-arounds, but it won't necessarily work universally.

This is my aproximation:

  Declare 
  Variableclob Clob;
  Temp_Save Varchar2(32767); //whether it is greater than 4000

  Begin
  Select reportClob Into Temp_Save From Reporte Where Id=...;
  Variableclob:=To_Clob(Temp_Save);
  Dbms_Output.Put_Line(Variableclob);


  End;

TLDR:First determine where in the pipeline you're getting the error from (scroll looking for screenshots of something that resembles your error), make changes to get something new, repeat.

First determine what error message you are actually seeing.

If you are seeing the file located here...

%SystemDrive%\inetpub\custerr\\500.htm

...which generally looks like this:

...then you know you are seeing the currently configured error page in **IIS ** and you do NOT need to change the ASP.net customErrors setting, asp error detail setting, or "show friendly http errors" browser setting.

You may want to look at the above referenced path instead of trusting my screenshot just in case somebody changed it.

"Yes, I see the above described error..."

In this case, you are seeing the setting of <httpErrors> or in IIS Manager it's Error Pages --> Edit Feature Settings. The default for this is errorMode=DetailedLocalOnly at the server node level (as opposed to the site level) which means that while you will see this configured error page while remote, you should be able to log on locally to the server and see the full error which should look something like this:

You should have everything that you need at that point to fix the current error.

"But I don't see the detailed error even browsing on the server"

That leaves a couple of possibilities.

1. The browser you are using on the server is configured to use a proxy in its connection settings so it is not being seen as "local".
2. You're not actually browsing to the site you think you are browsing to - this commonly happens when there's a load balancer involved. Do a ping check to see if dns gives you an IP on the server or somewhere else.
3. You're site's httpErrors settings is set for "Custom" only. Change it to "DetailedLocalOnly". However, if you have a configuration error, this may not work since the site level httpErrors is also a configuration item. In that case proceed to #4
4. The default for httpErrors for all sites is set for "Custom". In this case you need to click on the top level server node in IIS Manager (and not a particular site) and change the httpErrors settings there to DetailedLocalOnly. If this is an internal server and you're not worried about divulging sensitive information, you could also set it to "Detailed" which will allow you to see the error from clients other than the server.
5. You're missing a module on the server like UrlRewrite (this one bites me a lot, and it often gives the generic message regardless of the httpErrors settings).

"Logging on to the server is not an option for me"

Change your site's httpErrors to "Detailed" so you can see it remotely. But if it doesn't work your error might already be a config error, see #3 immediately above. So you might be stuck with #4 or #5 and you're going to need somebody from your server team.

"I'm not seeing the error page described above. I'm seeing something different"

If you see this...

...and you expect to see something like this...

...then you need to change "Send errors to browser" to true in IIS Manager, under Site --> IIS --> ASP --> Debugging Properties

If you see this...

or this...

...you need to disable friendly errors in your browser or use fiddler's webview to look at the actual response vs what your browser chooses to show you.

If you see this...

...then custom errors is working but you don't have a custom error page (of course at this point were talking about .net and not classic asp). You need to change your customErrors tag in your web.config to RemoteOnly to view on the server, or Off to view remotely.

If you see something that is styled like your site, then custom errors is likely On or RemoteOnly and it's displaying the custom page (Views->Shared->Error.cshtml in MVC for example). That said, it is unlikely but possible that somebody changed the pages in IIS for httpErrors so see the first section on that.

You may not have access to the SQL, but if you have the DataSet or DataTable, you can certainly call the Sort() method.

More generally, under most circumstances, underscore functions that take a list and argument as the first two arguments, provide access to the list index as the next to last argument to the iterator. This is an important distinction when it comes to the two underscore functions, _.reduce and _.reduceRight, that take 'memo' as their third argument -- in the case of these two the index will not be the second argument, but the third:

var destination = (function() {
    var fields = ['_333st', 'offroad', 'fbi'];
    return _.reduce(waybillInfo.destination.split(','), function(destination, segment, index) {
        destination[fields[index]] = segment;
        return destination;
    }, {});
})();

console.log(destination);            
/*
_333st: "NYARFTW  TX"
fbi: "FTWUP"
offroad: "UP"

The following is better of course but not demonstrate my point:
var destination = _.object(['_333st', 'offroad', 'fbi'], waybillInfo.destination.split(','));
*/

So if you wanted you could get the index using underscore itself: _.last(_.initial(arguments)). A possible exception (I haven't tried) is _.map, as it can take an object instead of a list: "If list is a JavaScript object, iterator's arguments will be (value, key, list)." -- see: http://underscorejs.org/#map

You can use Membership operator:

def list = ['Grace','Rob','Emmy']
assert ('Emmy' in list)  

Membership operator Groovy

For Swift 3

let imageDataDict:[String: UIImage] = ["image": image]

  // post a notification
  NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict) 
  // `default` is now a property, not a method call

 // Register to receive notification in your class
 NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)

 // handle notification
 func showSpinningWheel(_ notification: NSNotification) {
        print(notification.userInfo ?? "")
        if let dict = notification.userInfo as NSDictionary? {
            if let id = dict["image"] as? UIImage{
                // do something with your image
            }
        }
 }

For Swift 4

let imageDataDict:[String: UIImage] = ["image": image]

  // post a notification
  NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict) 
  // `default` is now a property, not a method call

 // Register to receive notification in your class
 NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)

 // handle notification
 @objc func showSpinningWheel(_ notification: NSNotification) {
        print(notification.userInfo ?? "")
        if let dict = notification.userInfo as NSDictionary? {
            if let id = dict["image"] as? UIImage{
                // do something with your image
            }
        }
 }

This piece of code compares two lists both containing a field for a CultureCode like 'en-GB'. This will leave non existing translations in the list. (we needed a dropdown list for not-translated languages for articles)

var compared = supportedLanguages.Where(sl => !existingTranslations.Any(fmt => fmt.CultureCode == sl.Culture)).ToList();

The location of jfxrt.jar in Oracle Java 7 is:

<JRE_HOME>/lib/jfxrt.jar

The location of jfxrt.jar in Oracle Java 8 is:

<JRE_HOME>/lib/ext/jfxrt.jar

The <JRE_HOME> will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.

jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).

An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.

Use Oracle Java 8.

With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.

OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.

My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6

Yes, but only the Oracle JDK.

The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).

In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.

Example: Inside myWindow() on line 3 is the code you need to set the window in the center of the screen.

JFrame window;

public myWindow() {

    window = new JFrame();
    window.setSize(1200,800);
    window.setLocationRelativeTo(null); // this line set the window in the center of thr screen
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    window.getContentPane().setBackground(Color.BLACK);
    window.setLayout(null); // disable the default layout to use custom one.
    window.setVisible(true); // to show the window on the screen.
}

Replace your remote url like this:

git remote set-url origin https://<username>@github.com/<username>/<repo>.git

Aside from using %, age of empires III to lower case is age of empires iii so your query should be:

select *
from games
where lower(title) like 'age of empires iii%'

I think that the usage of @Html.LabelForModel() should be explained in more detail.

The LabelForModel Method returns an HTML label element and the property name of the property that is represented by the model.

You could refer to the following code:

Code in model:

using System.ComponentModel;

[DisplayName("MyModel")]
public class MyModel
{
    [DisplayName("A property")]
    public string Test { get; set; }
}

Code in view:

@Html.LabelForModel()
<div class="form-group">

    @Html.LabelFor(model => model.Test, new { @class = "control-label col-md-2" })

    <div class="col-md-10">
        @Html.EditorFor(model => model.Test)
        @Html.ValidationMessageFor(model => model.Test)
    </div>
</div>

Josh is correct but he left out one variation:

ALTER ROLE <role_name> IN DATABASE <db_name> SET search_path TO schema1,schema2;

Set the search path for the user, in one particular database.

Am afraid this question has been answered a few times, Pls take a look at the following if it's related

• Flexbox and Internet Explorer 11 (display:flex in <html>?)
• Flexbox not working in Internet Explorer 11
