Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

This sort of thing is one of the logistical reasons why Abort is deprecated. First and foremost, do not use Thread.Abort() to cancel or stop a thread if at all possible. Abort() should only be used to forcefully kill a thread that is not responding to more peaceful requests to stop in a timely fashion.

That being said, you need to provide a shared cancellation indicator that one thread sets and waits while the other thread periodically checks and gracefully exits. .NET 4 includes a structure designed specifically for this purpose, the CancellationToken.

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

There are tools which profile code and provide code coverage data. This lets you see (as code is run) how much of it is being called. You can get any of these tools to find out how much orphan code you have.

What's wrong with:

new Date(1293034567877);

This returns for me "Wed Dec 22 2010 16:16:07 GMT+0000 (GMT Standard Time)".

Or do you need to get the number out the json?

If your DBMS doesn't support distinct with multiple columns like this:

select distinct(col1, col2) from table

Multi select in general can be executed safely as follows:

select distinct * from (select col1, col2 from table ) as x

As this can work on most of the DBMS and this is expected to be faster than group by solution as you are avoiding the grouping functionality.

The code I use is:

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

You can disable the check (if you're really sure you know what you're doing) by using the --force option to git push.

-- Access: 
SELECT CHR(13) & CHR(10) 

-- SQL Server: 
SELECT CHAR(13) + CHAR(10)

I have a dialog box that uses the datepicker on it. It was always hidden. When I adjusted the z-index, the field on the lower form always showed up on the dialog.

I used a combination of solutions that I saw to resolve the issue.

$('.ui-datepicker', $form).datepicker({
                showButtonPanel: true,
                changeMonth: true,
                changeYear: true,
                dateFormat: "yy-M-dd",
                beforeShow: function (input) {
                    $(input).css({
                        "position": "relative",
                        "z-index": 999999
                    });
                },
                onClose: function () { $('.ui-datepicker').css({ 'z-index': 0  } ); }                    
            });

The before show ensures that datepicker always is on top when selected, but the onClose ensures that the z-index of the field gets reset so that it doesn't overlap on any dialogs opened later with a different datepicker.

A property, when it has no definition, is undefined. null is an object. It's type is null. undefined is not an object, its type is undefined.

This is a good article explaining the difference and also giving some examples.

null vs undefined

I would not make the primary key of the "info" table a composite of the two values from other tables.

Others can articulate the reasons better, but it feels wrong to have a column that is really made up of two pieces of information. What if you want to sort on the ID from the second table for some reason? What if you want to count the number of times a value from either table is present?

I would always keep these as two distinct columns. You could use a two-column primay key in mysql ...PRIMARY KEY(id_a, id_b)... but I prefer using a two-column unique index, and having an auto-increment primary key field.

For Excel POI:

sheetName.autoSizeColumn(cellnum); 

Josh's comments are spot on. If you are not super familiar with critical values I'd suggest playing with qt, reading the manual (?qt) in conjunction with looking at a look up table (LINK). When I first moved from SPSS to R I created a function that made critical t value look up pretty easy (I'd never use this now as it takes too much time and with the p values that are generally provided in the output it's a moot point). Here's the code for that:

critical.t <- function(){
    cat("\n","\bEnter Alpha Level","\n")
    alpha<-scan(n=1,what = double(0),quiet=T)
    cat("\n","\b1 Tailed or 2 Tailed:\nEnter either 1 or 2","\n")
    tt <- scan(n=1,what = double(0),quiet=T)
    cat("\n","\bEnter Number of Observations","\n")
    n <- scan(n=1,what = double(0),quiet=T)
    cat("\n\nCritical Value =",qt(1-(alpha/tt), n-2), "\n")
}

critical.t()

I learned something really useful and fundamental from here.

chaining functions is very usefull in this case which works on most jQuery Functions including on function output too.

It works because output of most jQuery functions are the input objects sets so you can use them right away and make it shorter and smarter

function showPhotos() {
    $(this).find("span").slideToggle();
}

$(".photos")
    .on("mouseenter", "li", showPhotos)
    .on("mouseleave", "li", showPhotos);

I had a slightly different variant of this issue: It was required to associate two different values with same key. Just posting it here in case it helps others, I have introduced a HashMap as the value:

/* @param frameTypeHash: Key -> Integer (frameID), Value -> HashMap (innerMap)
   @param innerMap: Key -> String (extIP), Value -> String
   If the key exists, retrieve the stored HashMap innerMap 
   and put the constructed key, value pair
*/
  if (frameTypeHash.containsKey(frameID)){
            //Key exists, add the key/value to innerHashMap
            HashMap innerMap = (HashMap)frameTypeHash.get(frameID);
            innerMap.put(extIP, connName+":"+frameType+":"+interfaceName);

        } else {
            HashMap<String, String> innerMap = new HashMap<String, String>();
            innerMap.put(extIP, connName+":"+frameType+":"+interfaceName);
            // This means the key doesn't exists, adding it for the first time
            frameTypeHash.put(frameID, innerMap );
        }
}

In the above code the key frameID is read from a input file's first string in each line, the value for frameTypeHash is constructed by splitting the remaining line and was stored as String object originally, over a period of time the file started having multiple lines (with different values) associated with same frameID key, so frameTypeHash was overwritten with last line as the value. I replaced the String object with another HashMap object as the value field, this helped in maintaining single key to different value mapping.

If your compiler supports C++11, you can simply do:

std::vector<int> v = {1, 2, 3, 4};

This is available in GCC as of version 4.4. Unfortunately, VC++ 2010 seems to be lagging behind in this respect.

Alternatively, the Boost.Assign library uses non-macro magic to allow the following:

#include <boost/assign/list_of.hpp>
...
std::vector<int> v = boost::assign::list_of(1)(2)(3)(4);

Or:

#include <boost/assign/std/vector.hpp>
using namespace boost::assign;
...
std::vector<int> v;
v += 1, 2, 3, 4;

But keep in mind that this has some overhead (basically, list_of constructs a std::deque under the hood) so for performance-critical code you'd be better off doing as Yacoby says.

With the new feature called Hooks from the React team which makes functional components to handle state changes.. your question can be solved easily

import React, { useState, useEffect } from 'react'
import ReactDOM from 'react-dom';

const Demo = props =>{
    const [text, setText] = useState("there");
    return props.logic(text, setText);
};

const App = () => {
    const [text, setText] = useState("hello");

    const componentDidMount = () =>{
        setText("hey");
    };
    useEffect(componentDidMount, []);

    const logic = (word, setWord) => (
        <div>
            <h1>{word}</h1>
            <input type="text" value={word} onChange={e => setWord(e.target.value)}></input>
            <h1>{text}</h1>
            <input type="text" value={text} onChange={e => setText(e.target.value)}></input>
        </div>
    );
    return <Demo logic={logic} />;
};

ReactDOM.render(<App />,document.getElementById("root"));

You can always use MacPorts...

You could try to find out if $? is empty by using the said script below:

# Code that may fail here
if [ -z "$?" ]
then
      echo "Code if not failed"
else
      echo "Code if failed"
fi

Specify the name of columns in the CSV in the load data infile statement.

The code is like this:

LOAD DATA INFILE '/path/filename.csv'
INTO TABLE table_name
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'
(column_name3, column_name5);

Here you go with adding data to only two columns(you can choose them with the name of the column) to the table.

The only thing you have to take care is that you have a CSV file(filename.csv) with two values per line(row). Otherwise please mention. I have a different solution.

Thank you.

You could use the BufferedStreams/readers and then use their buffer sizes.

I believe the BufferedXStreams are using 8192 as the buffer size, but like Ovidiu said, you should probably run a test on a whole bunch of options. Its really going to depend on the filesystem and disk configurations as to what the best sizes are.

This happens because you use the savedValue in the onCreate() method. The savedValue is updated in onRestoreInstanceState() method, but onRestoreInstanceState() is called after the onCreate() method. You can either:

1. Update the savedValue in onCreate() method, or
2. Move the code that use the new savedValue in onRestoreInstanceState() method.
   

But I suggest you to use the first approach, making the code like this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int display_mode = getResources().getConfiguration().orientation;

    if (display_mode == 1) {

        setContentView(R.layout.main_grid);
        mGrid = (GridView) findViewById(R.id.gridview);
        mGrid.setColumnWidth(95);
        mGrid.setVisibility(0x00000000);
        // mGrid.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

    } else {
        setContentView(R.layout.main_grid_land);
        mGrid = (GridView) findViewById(R.id.gridview);
        mGrid.setColumnWidth(95);
        Log.d("Mode", "land");
        // mGrid.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

    }
    if (savedInstanceState != null) {
        savedUser = savedInstanceState.getString("TEXT");
    } else {
        savedUser = ""
    }
    Log.d("savedUser", savedUser);
    if (savedUser.equals("admin")) { //value 0
        adapter.setApps(appManager.getApplications());
    } else if (savedUser.equals("prof")) { //value 1
        adapter.setApps(appManager.getTeacherApplications());
    } else {// default value
        appManager = new ApplicationManager(this, getPackageManager());
        appManager.loadApplications(true);
        bindApplications();
    }
}

I agree with @ZombieSheep. Just one more thing - I generally don't think that databases actually need be portable because you miss all the features your DBMS vendor provides. I think that migrating to another database would be the last thing one would consider. Just my $.02

You can use the following example:

<table id="purches">
    <thead>
        <tr>
            <th>ID</th>
            <th>Transaction Date</th>
            <th>Category</th>
            <th>Transaction Amount</th>
            <th>Offer</th>
        </tr>
    </thead>

    <!--  <tr th:each="person: ${list}"    >
            <td><li th:each="person: ${list}" th:text="|${person.description}|"></li></td>
            <td><li th:each="person: ${list}" th:text="|${person.price}|"></li></td>
            <td><li th:each="person: ${list}" th:text="|${person.available}|"></li></td>
            <td><li th:each="person: ${list}" th:text="|${person.from}|"></li></td>
            </tr>
    -->

    <tbody id="feedback">
    </tbody>
</table>

JavaScript file:

$.ajax({
    type: "POST",
    contentType: "application/json",
    url: "/search",
    data: JSON.stringify(search),
    dataType: 'json',
    cache: false,
    timeout: 600000,
    success: function (data) {
        //  var json = "<h4>Ajax Response</h4><pre>"  + JSON.stringify(data, null, 4) + "</pre>";
        // $('#feedback').html(json);
        //
        console.log("SUCCESS: ", data);
        //$("#btn-search").prop("disabled", false);

        for (var i = 0; i < data.length; i++) {
            //$("#feedback").append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td></tr>');
            $('#feedback').append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td></tr>');

            alert(data[i].accountNumber)
        }
    },
    error: function (e) {
        var json = "<h4>Ajax Response</h4><pre>" + e.responseText + "</pre>";
        $('#feedback').html(json);

        console.log("ERROR: ", e);
        $("#btn-search").prop("disabled", false);
    }
});

I simplified your code to isolate the test for "%" being in the cell. Once you get that to work, you can add in the rest of your code.

Try this:

Option Explicit


Sub DoIHavePercentSymbol()
   Dim rng As Range

   Set rng = ActiveCell

   Do While rng.Value <> Empty
        If InStr(rng.Value, "%") = 0 Then
            MsgBox "I know nothing about percentages!"
            Set rng = rng.Offset(1)
            rng.Select
        Else
            MsgBox "I contain a % symbol!"
            Set rng = rng.Offset(1)
            rng.Select
        End If
   Loop

End Sub

InStr will return the number of times your search text appears in the string. I changed your if test to check for no matches first.

The message boxes and the .Selects are there simply for you to see what is happening while you are stepping through the code. Take them out once you get it working.

Try it: sudo mysql_secure_installation

Work's in Ubuntu 18.04

It's working for me:

<%= image_tag( root_url + "images/rss.jpg", size: "50x50", :alt => "rss feed") -%>

Use:

$ du -ckx <DIR> | grep total | awk '{print $1}'

Where <DIR> is the directory you want to inspect.

The '-c' gives you grand total data which is extracted using the 'grep total' portion of the command, and the count in Kbytes is extracted with the awk command.

The only caveat here is if you have a subdirectory containing the text "total" it will get spit out as well.

Set the attribute android:animateLayoutChanges="true" inside the parent layout .

Put the view in a layout if its not and set android:animateLayoutChanges="true" for that layout.

NOTE: This works only from API Level 11+ (Android 3.0)

I had a similar problem to this where Firefox 3.5 worked fine and parsed my JSON data but Firefox 3.0.6 returned a parseerror. Turned out it was a blank space at the start of the JSON that caused Firefox 3.0.6 to throw an error. Removing the blank space fixed it

You can simply use Arrays.sort()

array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));

Working Example :

var array = [{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"VPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""},},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"adfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"bbfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}}];_x000D_

Here's a pl/pgsql function that locates records where any column contains a specific value. It takes as arguments the value to search in text format, an array of table names to search into (defaults to all tables) and an array of schema names (defaults all schema names).

It returns a table structure with schema, name of table, name of column and pseudo-column ctid (non-durable physical location of the row in the table, see System Columns)

See also the version on github based on the same principle but adding some speed and reporting improvements.

Examples of use in a test database:

• Search in all tables within public schema:

select * from search_columns('foobar');
 schemaname | tablename | columnname | rowctid 
------------+-----------+------------+---------
 public     | s3        | usename    | (0,11)
 public     | s2        | relname    | (7,29)
 public     | w         | body       | (0,2)
(3 rows)

• Search in a specific table:

 select * from search_columns('foobar','{w}');
 schemaname | tablename | columnname | rowctid 
------------+-----------+------------+---------
 public     | w         | body       | (0,2)
(1 row)

• Search in a subset of tables obtained from a select:

select * from search_columns('foobar', array(select table_name::name from information_schema.tables where table_name like 's%'), array['public']);
 schemaname | tablename | columnname | rowctid 
------------+-----------+------------+---------
 public     | s2        | relname    | (7,29)
 public     | s3        | usename    | (0,11)
(2 rows)

• Get a result row with the corresponding base table and and ctid:

select * from public.w where ctid='(0,2)';
 title |  body  |         tsv         
-------+--------+---------------------
 toto  | foobar | 'foobar':2 'toto':1

Variants

• To test against a regular expression instead of strict equality, like grep, this part of the query:

  SELECT ctid FROM %I.%I WHERE cast(%I as text)=%L

  may be changed to:

  SELECT ctid FROM %I.%I WHERE cast(%I as text) ~ %L

• For case insensitive comparisons, you could write:

  SELECT ctid FROM %I.%I WHERE lower(cast(%I as text)) = lower(%L)

Just an important note: the accepted answer above will not work correctly for keyCode >= 144, i.e. period, comma, dash, etc. For those you should use a more general algorithm:

let chrCode = keyCode - 48 * Math.floor(keyCode / 48);
let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);

If you're curious as to why, this is apparently necessary because of the behavior of the built-in JS function String.fromCharCode(). For values of keyCode <= 96 it seems to map using the function:

chrCode = keyCode - 48 * Math.floor(keyCode / 48)

For values of keyCode > 96 it seems to map using the function:

chrCode = keyCode

If this seems like odd behavior then well..I agree. Sadly enough, it would be very far from the weirdest thing I've seen in the JS core.

document.onkeydown = function(e) {_x000D_
    let keyCode = e.keyCode;_x000D_
    let chrCode = keyCode - 48 * Math.floor(keyCode / 48);_x000D_
    let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);_x000D_
    console.log(chr);_x000D_
};

<input type="text" placeholder="Focus and Type"/>

you can do something like this:

        request.HTTPMethod = "POST"
        request.addValue("application/json",forHTTPHeaderField: "Content-Type")
        request.addValue("application/json",forHTTPHeaderField: "Accept")
        request.HTTPBody = data
        HTTPsendRequest(request, callback: callback)
}

func HTTPsendRequest(request: NSMutableURLRequest,
    callback: (String, String?) -> Void) {

I know this is too old thread but why no one mentioned this

#!/usr/bin/python3
import asyncio 

loop = asyncio.get_event_loop()
try:
    loop.run_forever()
finally:
    loop.close()

You should delete the file: c:\users\_user_name_\.android\adbkey

Or use good old "find". For example in order to look for old mysql v5.7:

cd /
find . type -d -name "[email protected]"

Setup:

My OS windows 8 64bit
Eclipse version Standard/SDK Kepler Service Release 2
My JDK is jdk-8u5-windows-i586
My JRE is jre-8u5-windows-i586

This how I overcome my error.

At the very first my Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") also didn't work. Then I login to this website and downloaded the UCanAccess 2.0.8 zip (as Mr.Gord Thompson said) file and unzip it.

Then you will also able to find these *.jar files in that unzip folder:

ucanaccess-2.0.8.jar
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.0.4.jar

Then what I did was I copied all these 5 files and paste them in these 2 locations:

C:\Program Files (x86)\eclipse\lib
C:\Program Files (x86)\eclipse\lib\ext

(I did that funny thing becoz I was unable to import these libraries to my project)

Then I reopen the eclipse with my project.then I see all that *.jar files in my project's JRE System Library folder.

Finally my code works.

public static void main(String[] args) 
{

    try
    {

        Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\Hasith\\Documents\\JavaDatabase1.mdb");
        Statement stment = conn.createStatement();
        String qry = "SELECT * FROM Table1";

        ResultSet rs = stment.executeQuery(qry);
        while(rs.next())
        {
            String id    = rs.getString("ID") ;
            String fname = rs.getString("Nama");

            System.out.println(id + fname);
        }
    }
    catch(Exception err)
    {
        System.out.println(err);
    }


    //System.out.println("Hasith Sithila");

}

To make a custom "browse button" solution simply try making a hidden browse button, a custom button or element and some Jquery. This way I'm not modifying the actual "browse button" which is dependent on each browser/version. Here's an example.

HTML:

<div id="import" type="file">My Custom Button</div>
<input id="browser" class="hideMe" type="file"></input>

CSS:

#import {
  margin: 0em 0em 0em .2em;
  content: 'Import Settings';
  display: inline-block;
  border: 1px solid;
  border-color: #ddd #bbb #999;
  border-radius: 3px;
  padding: 5px 8px;
  outline: none;
  white-space: nowrap;
  -webkit-user-select: none;
  cursor: pointer;
  font-weight: 700;
  font: bold 12px/1.2 Arial,sans-serif !important;
  /* fallback */
  background-color: #f9f9f9;
  /* Safari 4-5, Chrome 1-9 */
  background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#C2C1C1), to(#2F2727));
}

.hideMe{
    display: none;
}

JS:

$("#import").click(function() {
    $("#browser").trigger("click");
    $('#browser').change(function() {
            alert($("#browser").val());
    });
});

If you can use only Java 8 or lower:

1) if you don't have spring-data the best way so far is:

opt.<Runnable>map(param -> () -> System.out.println(param))
      .orElse(() -> System.out.println("no-param-specified"))
      .run();

Now I know it's not so readable and even hard to understand for someone, but looks fine for me personally and I don't see another nice fluent way for this case.

2) if you're lucky enough and you can use spring-data the best way is Optionals#ifPresentOrElse:

Optionals.ifPresentOrElse(opt, System.out::println,
      () -> System.out.println("no-param-specified"));

If you can use Java 9, you should definitely go with:

opt.ifPresentOrElse(System.out::println,
      () -> System.out.println("no-param-specified"));

It returns a string because 0.1, and powers thereof (which are used to display decimal fractions), are not representable (at least not with full accuracy) in binary floating-point systems.

For example, 0.1 is really 0.1000000000000000055511151231257827021181583404541015625, and 0.01 is really 0.01000000000000000020816681711721685132943093776702880859375. (Thanks to BigDecimal for proving my point. :-P)

Therefore (absent a decimal floating point or rational number type), outputting it as a string is the only way to get it trimmed to exactly the precision required for display.

There's a facility to have a separate style sheet for print, using

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

I don't know if it does what you want though.

JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("document.querySelector('attributeValue').value='new value'");

Angular 2 completely ignores type=date. If you change type to text you'll see that your input has two-way binding.

<input type='text' #myDate [(ngModel)]='demoUser.date'/><br>

Here is pretty bad advise with better one to follow:

My project originally used jQuery. So, I'm using jQuery datepicker for now, hoping that angular team will fix the original issue. Also it's a better replacement because it has cross-browser support. FYI, input=date doesn't work in Firefox.

Good advise: There are few pretty good Angular2 datepickers:

• https://github.com/emirdeliz/meus-projetos/tree/master/angular2-schedule/app/frontend/components/datepicker

• https://github.com/MrPardeep/Angular2-DatePicker

• https://www.npmjs.com/package/ng2-datepicker

I was facing the same issue. On GitHub I found the Android-LocalizationActivity library.

This library makes it very simple to change the language of your app at runtime, as you can see in the code sample below. A sample project including the sample code below and more information can be found at the github page.

The LocalizationActivity extends AppCompatActivity, so you can also use it when you are using Fragments.

public class MainActivity extends LocalizationActivity implements View.OnClickListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_simple);

        findViewById(R.id.btn_th).setOnClickListener(this);
        findViewById(R.id.btn_en).setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        int id = v.getId();
        if (id == R.id.btn_en) {
            setLanguage("en");
        } else if (id == R.id.btn_th) {
            setLanguage("th");
        }
    }
}

You can use this function :

send_static_file(filename)
Function used internally to send static files from the static folder to the browser.

app = Flask(__name__)
@app.route('/<path:path>')
def static_file(path):
    return app.send_static_file(path)

I would suggest to use a variable instead of a public field:

public class Variables
{
   private static string name = "";

   public static string Name
   { 
        get { return name; }
        set { name = value; }

   }
}

From another class, you call your variable like this:

public class Main
{
    public void DoSomething()
    {
         string var = Variables.Name;
    }
}

You can copy subscribers dictionary object to a same type of temporary dictionary object and then iterate the temporary dictionary object using foreach loop.

VARCHAR is variable-length.

CHAR is fixed length.

If your content is a fixed size, you'll get better performance with CHAR.

See the MySQL page on CHAR and VARCHAR Types for a detailed explanation (be sure to also read the comments).

If your system has systemctl

sudo systemctl reload nginx

If your system supports service (using debian/ubuntu) try this

sudo service nginx reload

If not (using centos/fedora/etc) you can try the init script

sudo /etc/init.d/nginx reload

HashMap<String, ArrayList<Item>> items = new HashMap<String, ArrayList<Item>>();

public synchronized void addToList(String mapKey, Item myItem) {
    List<Item> itemsList = items.get(mapKey);

    // if list does not exist create it
    if(itemsList == null) {
         itemsList = new ArrayList<Item>();
         itemsList.add(myItem);
         items.put(mapKey, itemsList);
    } else {
        // add if item is not already in list
        if(!itemsList.contains(myItem)) itemsList.add(myItem);
    }
}

Method 1

public static void increaseFontSizeForPath(Spannable spannable, String path, float increaseTime) {
    int startIndexOfPath = spannable.toString().indexOf(path);
    spannable.setSpan(new RelativeSizeSpan(increaseTime), startIndexOfPath,
            startIndexOfPath + path.length(), 0);
}

using

Utils.increaseFontSizeForPath(spannable, "big", 3); // make "big" text bigger 3 time than normal text

Method 2

public static void setFontSizeForPath(Spannable spannable, String path, int fontSizeInPixel) {
    int startIndexOfPath = spannable.toString().indexOf(path);
    spannable.setSpan(new AbsoluteSizeSpan(fontSizeInPixel), startIndexOfPath,
            startIndexOfPath + path.length(), 0);
}

using

Utils.setFontSizeForPath(spannable, "big", (int) textView.getTextSize() + 20); // make "big" text bigger 20px than normal text

Try

[...mySelect.options].forEach(o=> o.selected = o.text == 'Text C' )

[...mySelect.options].forEach(o=> o.selected = o.text == 'Text C' );

<select id="mySelect">
  <option value="A">Text A</option>
  <option value="B">Text B</option>
  <option value="C">Text C</option>
</select>

What about normal encoded white-space character?

 

I think what you mean is how to encapsulate that for general use, e.g. in a function:

def sum_list(l):
    sum = 0
    for x in l:
        sum += x
    return sum

Now you can apply this to any list. Examples:

l = [1, 2, 3, 4, 5]
sum_list(l)

l = list(map(int, input("Enter numbers separated by spaces: ").split()))
sum_list(l)

But note that sum is already built in!

Hash functions for algorithmic use have usually 2 goals, first they have to be fast, second they have to evenly distibute the values across the possible numbers. The hash function also required to give the all same number for the same input value.

if your values are strings, here are some examples for bad hash functions:

1. string[0] - the ASCII characters a-Z are way more often then others
2. string.lengh() - the most probable value is 1

Good hash functions tries to use every bit of the input while keeping the calculation time minimal. If you only need some hash code, try to multiply the bytes with prime numbers, and sum them.

If you have a file in your repo that it is supposed to be customized by most pullers, then rename the file to something like config.php.template and add config.php to your .gitignore.

In Chrome is keys(foo.prototype). Returns ["a", "b"].

See: https://developer.chrome.com/devtools/docs/commandline-api#keysobject

Later edit: If you need to copy it quick (for bigger objects), do copy(keys(foo.prototype)) and you will have it in the clipboard.

You also need to replace your indexes:

class RenameOldTableToNewTable< ActiveRecord:Migration
  def self.up
    remove_index :old_table_name, :column_name
    rename_table :old_table_name, :new_table_name
    add_index :new_table_name, :column_name
  end 

  def self.down
    remove_index :new_table_name, :column_name
    rename_table :new_table_name, :old_table_name
    add_index :old_table_name, :column_name
  end
end

And rename your files etc, manually as other answers here describe.

See: http://api.rubyonrails.org/classes/ActiveRecord/Migration.html

Make sure you can rollback and roll forward after you write this migration. It can get tricky if you get something wrong and get stuck with a migration that tries to effect something that no longer exists. Best trash the whole database and start again if you can't roll back. So be aware you might need to back something up.

Also: check schema_db for any relevant column names in other tables defined by a has_ or belongs_to or something. You'll probably need to edit those too.

And finally, doing this without a regression test suite would be nuts.

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

Use like this

<a href="index.php">Index Page</a>
<a href="page2.php">Page 2</a>

cant say why, but the es5/6 syntax doesnt work

elem.onclick = (ev) => {console.log(this);} not working

elem.onclick = function(ev) {console.log(this);} working

I solved a similar problem by passing the value of the available parameter in the URL instead of the label of the parameter.

For instance, I have a report with a parameter named viewName and the predefined Available Values for the parameter are: (labels/values) orders/sub_orders, orderDetail/sub_orderDetail, product/sub_product.

To call this report with a URL to render automatically for parameter=product, you must specify the value not the label.
This would be wrong: http://server/reportserver?/Data+Dictionary/DetailedInfo&viewName=product&rs:Command=Render

This is correct: http://server/reportserver?/Data+Dictionary/DetailedInfo&viewName=sub_product&rs:Command=Render

I'll try and explain it as simple as possible. So there is no guarantee of the accuracy of the actual terms.

Session is where to initiate the connectivity to AWS services. E.g. following is default session that uses the default credential profile(e.g. ~/.aws/credentials, or assume your EC2 using IAM instance profile )

sqs = boto3.client('sqs')
s3 = boto3.resource('s3')

Because default session is limit to the profile or instance profile used, sometimes you need to use the custom session to override the default session configuration (e.g. region_name, endpoint_url, etc. ) e.g.

# custom resource session must use boto3.Session to do the override
my_west_session = boto3.Session(region_name = 'us-west-2')
my_east_session = boto3.Session(region_name = 'us-east-1')
backup_s3 = my_west_session.resource('s3')
video_s3 = my_east_session.resource('s3')

# you have two choices of create custom client session. 
backup_s3c = my_west_session.client('s3')
video_s3c = boto3.client("s3", region_name = 'us-east-1')

Resource : This is the high-level service class recommended to be used. This allows you to tied particular AWS resources and passes it along, so you just use this abstraction than worry which target services are pointed to. As you notice from the session part, if you have a custom session, you just pass this abstract object than worrying about all custom regions,etc to pass along. Following is a complicated example E.g.

import boto3 
my_west_session = boto3.Session(region_name = 'us-west-2')
my_east_session = boto3.Session(region_name = 'us-east-1')
backup_s3 = my_west_session.resource("s3")
video_s3 = my_east_session.resource("s3")
backup_bucket = backup_s3.Bucket('backupbucket') 
video_bucket = video_s3.Bucket('videobucket')

# just pass the instantiated bucket object
def list_bucket_contents(bucket):
   for object in bucket.objects.all():
      print(object.key)

list_bucket_contents(backup_bucket)
list_bucket_contents(video_bucket)

Client is a low level class object. For each client call, you need to explicitly specify the targeting resources, the designated service target name must be pass long. You will lose the abstraction ability.

For example, if you only deal with the default session, this looks similar to boto3.resource.

import boto3 
s3 = boto3.client('s3')

def list_bucket_contents(bucket_name):
   for object in s3.list_objects_v2(Bucket=bucket_name) :
      print(object.key)

list_bucket_contents('Mybucket') 

However, if you want to list objects from a bucket in different regions, you need to specify the explicit bucket parameter required for the client.

import boto3 
backup_s3 = my_west_session.client('s3',region_name = 'us-west-2')
video_s3 = my_east_session.client('s3',region_name = 'us-east-1')

# you must pass boto3.Session.client and the bucket name 
def list_bucket_contents(s3session, bucket_name):
   response = s3session.list_objects_v2(Bucket=bucket_name)
   if 'Contents' in response:
     for obj in response['Contents']:
        print(obj['key'])

list_bucket_contents(backup_s3, 'backupbucket')
list_bucket_contents(video_s3 , 'videobucket') 

Just try to set the Projects Encoding to "UTF-8" and copy the file (which is encoded in iso) in the same Project (and if you dont need the old file just delete it) - now the copied file will be as UTF-8 - maybe this will help you :)

Don't :-

xyz = Blogs.objects.get(user_id=id)

Use:-

xyz = Blogs.objects.all().filter(user_id=id)

I know this is an old item, but thought I'd throw in another option to consider.

As the original string doesn't include the "T" demarker, the default implementation in Angular doesn't recognize it as a date. You can force it using new Date, but that is a bit of a pain on an array. Since you can pipe filters together, you might be able to use a filter to convert your input to a date and then apply the date: filter on the converted date. Create a new custom filter as follows:

app
.filter("asDate", function () {
    return function (input) {
        return new Date(input);
    }
});

Then in your markup, you can pipe the filters together:

{{item.myDateTimeString | asDate | date:'shortDate'}}

None of the previous solutions worked for me. Finally I found that the action should be coded as:

public ActionResult Index(string MyCheck = null)

and then, when checked the passed value was "on", not "true". Else, it is always null.

Hope it helps somebody!

In my case I wanted the "null distribution" amongst multiple columns:

SELECT
       (CASE WHEN a IS NULL THEN 'NULL' ELSE 'NOT-NULL' END) AS a_null,
       (CASE WHEN b IS NULL THEN 'NULL' ELSE 'NOT-NULL' END) AS b_null,
       (CASE WHEN c IS NULL THEN 'NULL' ELSE 'NOT-NULL' END) AS c_null,
       ...
       count(*)
FROM us
GROUP BY 1, 2, 3,...
ORDER BY 1, 2, 3,...

As per the '...' it is easily extendable to more columns, as many as needed

Things have changed quite a bit since this question was asked. There are now options to let Google index your AngularJS site. The easiest option I found was to use http://prerender.io free service that will generate the crwalable pages for you and serve that to the search engines. It is supported on almost all server side web platforms. I have recently started using them and the support is excellent too.

I do not have any affiliation with them, this is coming from a happy user.

Notifications appear to have changed again (October 2016).

// Register to receive notification

NotificationCenter.default.addObserver(self, selector: #selector(yourClass.yourMethod), name: NSNotification.Name(rawValue: "yourNotificatioName"), object: nil)

// Post notification

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "yourNotificationName"), object: nil)

Another variation you can try is(expanding @mnel's answer) if you have many temp'x'.

here "n" could be the number of temp variables present

rm(list = c(paste("temp",c(1:n),sep="")))

Tried installing it via rpm posted in above answers, but it didn't worked. What worked instead is plain pip install.

pip install cx_oracle

The above command installed cx_oracle=6.1 Please note that I'm using python 2.7.14 Anaconda release and oracle 12c.

Use a real dropdown menu instead: a list (ul, li) and links. Never misuse form elements as links.

Readers with screen readers usually scan through a automagically generated list of links – the’ll miss these important information. Many keyboard navigation systems (e.g. JAWS, Opera) offer different keyboard shortcuts for links and form elements.

If you still cannot drop the idea of a select don’t use the onchange handler at least. This is a real pain for keyboard users, it makes your third item nearly inaccessible.

I'm not sure of your exact requirement but one possible solution to improve 'readability' is to store it as an array.

{
  "testCases" :
  {
    "case.1" :
    {
      "scenario" : "this the case 1.",
      "result" : ["this is a very long line which is not easily readble.",
                  "so i would like to write it in multiple lines.",
                  "but, i do NOT require any new lines in the output."]
    }
  }
}

}

The join in back again whenever required with

result.join(" ")

I'm pretty sure that the join doesn't even do what you want. If there are 100 records in table a with a null qid and 100 records in table b with a null qid, then the join as written should make a cross join and give 10,000 results for those records. If you look at the following code and run the examples, I think that the last one is probably more the result set you intended:

create table #test1 (id int identity, qid int)
create table #test2 (id int identity, qid int)

Insert #test1 (qid)
select null
union all
select null
union all
select 1
union all
select 2
union all
select null

Insert #test2 (qid)
select null
union all
select null
union all
select 1
union all
select 3
union all
select null


select * from #test2 t2
join #test1 t1 on t2.qid = t1.qid

select * from #test2 t2
join #test1 t1 on isnull(t2.qid, 0) = isnull(t1.qid, 0)


select * from #test2 t2
join #test1 t1 on 
 t1.qid = t2.qid OR ( t1.qid IS NULL AND t2.qid IS NULL )


select t2.id, t2.qid, t1.id, t1.qid from #test2 t2
join #test1 t1 on t2.qid = t1.qid
union all
select null, null,id, qid from #test1 where qid is null
union all
select id, qid, null, null from #test2  where qid is null

If the code should be simple, then you probably asking for C example based on traditional BSD sockets. Solutions like boost::asio are imho quite complicated when it comes to short and simple "hello world" example.

To compile examples you mentioned you must make simple fixes, because you are compiling under C++ compiler. I'm referring to following files:
http://www.linuxhowtos.org/data/6/server.c
http://www.linuxhowtos.org/data/6/client.c
from: http://www.linuxhowtos.org/C_C++/socket.htm

1. Add following includes to both files:

   #include <cstdlib>
   #include <cstring>
   #include <unistd.h>
   

2. In client.c, change the line:

   if (connect(sockfd,&serv_addr,sizeof(serv_addr)) < 0)
   { ... }
   

   to:

   if (connect(sockfd,(const sockaddr*)&serv_addr,sizeof(serv_addr)) < 0)
   { ... }
   

As you can see in C++ an explicit cast is needed.

Try to define the account in a ~/.netrc file like this:

Gradle can work with the 18.0.+ notation, it however now depends on the new support repository which is now bundled with the SDK.

Open the SDK manager and immediately under Extras the first option is "Android Support Repository" and install it

Another legal alternative to get movie info is the Rotten-Tomatoes API (by Fandango).

Comparing sequencially the letters that have the same position against each other.. more like how you order words in a dictionary

I did it this way:

var xlApp = new Excel.Application();
var xlWorkBook = xlApp.Workbooks.Add(System.Reflection.Missing.Value);
var xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.Item[1];
xlWorkSheet.Columns.AutoFit();

With this way, columns always fit to text width inside cells.

Hope it helps to someone!

For MySQL (INNODB) ... get definitions for columns you want to link

SELECT * FROM information_schema.columns WHERE 
TABLE_NAME IN (tb_name','referenced_table_name') AND 
COLUMN_NAME  IN ('col_name','referenced_col_name')\G

compare and verify both column definitions have

same COLUMN_TYPE(length), same COLATION

could be helpfull to play like

set foreign_key_checks=0;
ALTER TABLE tb_name ADD FOREIGN KEY(col_name) REFERENCES ref_table(ref_column) ON DELETE ...
set foreign_key_checks=1;

This is my 2 cents based on Grax's answer, but with two parameters required for a generic method.

Assume your method is defined as follows in an Helpers class:

public class Helpers
{
    public static U ConvertCsvDataToCollection<U, T>(string csvData)
    where U : ObservableCollection<T>
    {
      //transform code here
    }
}

In my case, U type is always an observable collection storing object of type T.

As I have my types predefined, I first create the "dummy" objects that represent the observable collection (U) and the object stored in it (T) and that will be used below to get their type when calling the Make

object myCollection = Activator.CreateInstance(collectionType);
object myoObject = Activator.CreateInstance(objectType);

Then call the GetMethod to find your Generic function:

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

So far, the above call is pretty much identical as to what was explained above but with a small difference when you need have to pass multiple parameters to it.

You need to pass an Type[] array to the MakeGenericMethod function that contains the "dummy" objects' types that were create above:

MethodInfo generic = method.MakeGenericMethod(
new Type[] {
   myCollection.GetType(),
   myObject.GetType()
});

Once that's done, you need to call the Invoke method as mentioned above.

generic.Invoke(null, new object[] { csvData });

And you're done. Works a charm!

UPDATE:

As @Bevan highlighted, I do not need to create an array when calling the MakeGenericMethod function as it takes in params and I do not need to create an object in order to get the types as I can just pass the types directly to this function. In my case, since I have the types predefined in another class, I simply changed my code to:

object myCollection = null;

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

MethodInfo generic = method.MakeGenericMethod(
   myClassInfo.CollectionType,
   myClassInfo.ObjectType
);

myCollection = generic.Invoke(null, new object[] { csvData });

myClassInfo contains 2 properties of type Type which I set at run time based on an enum value passed to the constructor and will provide me with the relevant types which I then use in the MakeGenericMethod.

Thanks again for highlighting this @Bevan.

Everyone here seems to think that implementing Runnable is the way to go and I don't really disagree with them but there is also a case for extending Thread in my opinion, in fact you have sort of demonstrated it in your code.

If you implement Runnable then the class that implements Runnable has no control over the thread name, it is the calling code that can set the thread name, like so:

new Thread(myRunnable,"WhateverNameiFeelLike");

but if you extend Thread then you get to manage this within the class itself (just like in your example you name the thread 'ThreadB'). In this case you:

A) might give it a more useful name for debugging purposes

B) are forcing that that name be used for all instances of that class (unless you ignore the fact that it is a thread and do the above with it as if it is a Runnable but we are talking about convention here in any case so can ignore that possibility I feel).

You might even for example take a stack trace of its creation and use that as the thread name. This might seem odd but depending on how your code is structured it can be very useful for debugging purposes.

This might seem like a small thing but where you have a very complex application with a lot of threads and all of a sudden things 'have stopped' (either for reasons of deadlock or possibly because of a flaw in a network protocol which would be less obvious - or other endless reasons) then getting a stack dump from Java where all the threads are called 'Thread-1','Thread-2','Thread-3' is not always very useful (it depends on how your threads are structured and whether you can usefully tell which is which just by their stack trace - not always possible if you are using groups of multiple threads all running the same code).

Having said that you could of course also do the above in a generic way by creating an extension of the thread class which sets its name to a stack trace of its creation call and then use that with your Runnable implementations instead of the standard java Thread class (see below) but in addition to the stack trace there might be more context specific information that would be useful in the thread name for debugging (a reference to one of many queues or sockets it could processing for example in which case you might prefer to extend Thread specifically for that case so that you can have the compiler force you (or others using your libraries) to pass in certain info (e.g. the queue/socket in question) for use in the name).

Here's an example of the generic thread with the calling stack trace as its name:

public class DebuggableThread extends Thread {
    private static String getStackTrace(String name) {
        Throwable t= new Throwable("DebuggableThread-"+name);
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        PrintStream ps = new PrintStream(os);
        t.printStackTrace(ps);
        return os.toString();
    }

    public DebuggableThread(String name) {
        super(getStackTrace(name));
    }

    public static void main(String[] args) throws Exception {
        System.out.println(new Thread());
        System.out.println(new DebuggableThread("MainTest"));
    }
}

and here's a sample of the output comparing the two names:

Thread[Thread-1,5,main]
Thread[java.lang.Throwable: DebuggableThread-MainTest
    at DebuggableThread.getStackTrace(DebuggableThread.java:6)
    at DebuggableThread.<init>(DebuggableThread.java:14)
    at DebuggableThread.main(DebuggableThread.java:19)
,5,main]

The reason why Python3 lacks a function for directly getting a ranged list is because the original Python3 designer was quite novice in Python2. He only considered the use of range() function in a for loop, thus, the list should never need to be expanded. In fact, very often we do need to use the range() function to produce a list and pass into a function.

Therefore, in this case, Python3 is less convenient as compared to Python2 because:

• In Python2, we have xrange() and range();
• In Python3, we have range() and list(range())

Nonetheless, you can still use list expansion in this way:

[*range(N)]

As lyyons pointed out in the comments, more idiomatic and lodashy way to do this would be to use _.remove, like this

_.remove(obj.subTopics, {
    subTopicId: stToDelete
});

Apart from that, you can pass a predicate function whose result will be used to determine if the current element has to be removed or not.

_.remove(obj.subTopics, function(currentObject) {
    return currentObject.subTopicId === stToDelete;
});

Alternatively, you can create a new array by filtering the old one with _.filter and assign it to the same object, like this

obj.subTopics = _.filter(obj.subTopics, function(currentObject) {
    return currentObject.subTopicId !== stToDelete;
});

Or

obj.subTopics = _.filter(obj.subTopics, {subTopicId: stToKeep});

var listItems = $("#myList").children();

var count = listItems.length;

Of course you can condense this with

var count = $("#myList").children().length;

The latest version of SQL Server (2012) permits the following.

SELECT 
    RowID, 
    Col1,
    SUM(Col1) OVER(ORDER BY RowId ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS Col2
FROM tablehh
ORDER BY RowId

or

SELECT 
    GroupID, 
    RowID, 
    Col1,
    SUM(Col1) OVER(PARTITION BY GroupID ORDER BY RowId ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS Col2
FROM tablehh
ORDER BY RowId

This is even faster. Partitioned version completes in 34 seconds over 5 million rows for me.

Thanks to Peso, who commented on the SQL Team thread referred to in another answer.

You can also say:

cut -d\  -f 2

Note that there are two spaces after the backslash.

to answer to your second question - performance IS affected - if you are using those selectors with a single (no nested) ul:

<ul>
    <li>jjj</li>
    <li>jjj</li>    
    <li>jjj</li>
</ul>

the child selector ul > li is more performant than ul li because it is more specific. the browser traverse the dom "right to left", so when it finds a li it then looks for a any ul as a parent in the case of a child selector, while it has to traverse the whole dom tree to find any ul ancestors in case of the descendant selector

Fatal Error gave a straightforward possibility: source your second script! if you're worried that this second script may alter some of your precious variables, you can always source it in a subshell:

( . ./test2.sh )

The parentheses will make the source happen in a subshell, so that the parent shell will not see the modifications test2.sh could perform.

There's another possibility that should definitely be referenced here: use set -a.

From the POSIX set reference:

-a: When this option is on, the export attribute shall be set for each variable to which an assignment is performed; see the Base Definitions volume of IEEE Std 1003.1-2001, Section 4.21, Variable Assignment. If the assignment precedes a utility name in a command, the export attribute shall not persist in the current execution environment after the utility completes, with the exception that preceding one of the special built-in utilities causes the export attribute to persist after the built-in has completed. If the assignment does not precede a utility name in the command, or if the assignment is a result of the operation of the getopts or read utilities, the export attribute shall persist until the variable is unset.

From the Bash Manual:

-a: Mark variables and function which are modified or created for export to the environment of subsequent commands.

So in your case:

set -a
TESTVARIABLE=hellohelloheloo
# ...
# Here put all the variables that will be marked for export
# and that will be available from within test2 (and all other commands).
# If test2 modifies the variables, the modifications will never be
# seen in the present script!
set +a

./test2.sh

 # Here, even if test2 modifies TESTVARIABLE, you'll still have
 # TESTVARIABLE=hellohelloheloo

Observe that the specs only specify that with set -a the variable is marked for export. That is:

set -a
a=b
set +a
a=c
bash -c 'echo "$a"'

will echo c and not an empty line nor b (that is, set +a doesn't unmark for export, nor does it “save” the value of the assignment only for the exported environment). This is, of course, the most natural behavior.

Conclusion: using set -a/set +a can be less tedious than exporting manually all the variables. It is superior to sourcing the second script, as it will work for any command, not only the ones written in the same shell language.

Try this,

Using foreach Loop:

foreach (GridViewRow row in GridView1.Rows)
{
     CheckBox chk = row.Cells[0].Controls[0] as CheckBox;
     if (chk != null && chk.Checked)
     {
       // ...
     }
}

Use it in OnRowCommand event and get checked CheckBox value.

GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
int requisitionId = Convert.ToInt32(e.CommandArgument);
CheckBox cbox = (CheckBox)row.Cells[3].Controls[0];

I have a crossplatform solution without any additional modules. I was looking for something like a try catch block I could use both in the cmd.exe and in the bash.

The solution is command1 || command2 which seems to work in both enviroments same. So the solution for the OP is:

"scripts": {
  "start-watch": "nodemon run-babel index.js",
  "wp-server": "webpack-dev-server",
  // first command is for the cmd.exe, second one is for the bash
  "dev": "(start npm run start-watch && start npm run wp-server) || (npm run start-watch & npm run wp-server)",
  "start": "npm run dev"
}

Then simple npm start (and npm run dev) will work on all platforms!

This is the first answer when Googling 'require': cannot load such file -- ubygems (LoadError) after Google autocorrected "ubygems" to "rubygems". Turns out this was an intentional change between Ruby 2.4 and 2.5 (Bug #14322). Scripts that detect the user gems directory without taking into account the ruby version will most likely fail.

Ruby 2.4

ruby -rubygems -e 'puts Gem.user_dir'

Ruby 2.5

ruby -rrubygems -e 'puts Gem.user_dir'

I couldn't possibly explain it better than wikipedia does: http://en.wikipedia.org/wiki/MIME_type

In addition to e-mail applications, Web browsers also support various MIME types. This enables the browser to display or output files that are not in HTML format.

IOW, it helps the browser (or content consumer, because it may not just be a browser) determine what content they are about to consume; this means a browser may be able to make a decision on the correct plugin to use to display content, or a media player may be able to load up the correct codec or plugin.

Here's an example of NPX in action: npx cowsay hello

If you type that into your bash terminal you'll see the result. The benefit of this is that npx has temporarily installed cowsay. There is no package pollution since cowsay is not permanently installed. This is great for one off packages where you want to avoid package pollution.

As mentioned in other answers, npx is also very useful in cases where (with npm) the package needs to be installed then configured before running. E.g. instead of using npm to install and then configure the json.package file and then call the configured run command just use npx instead. A real example: npx create-react-app my-app

We have to dynamically set the attribute target="_blank" and it will open it in new tab. document.getElementsByTagName("a")[0].setAttribute('target', '_blank')

document.getElementsByTagName("a")[0].click()

If you want to open in new window, get the href link and use window.open

var link = document.getElementsByTagName("a")[0].getAttribute("href");

window.open(url, "","height=500,width=500");

Don't provide the second parameter as _blank in the above.

Matlab help says this- For M-files that run a long time, or that call built-ins or MEX-files that run a long time, Ctrl+C does not always effectively stop execution. Typically, this happens on Microsoft Windows platforms rather than UNIX[1] platforms. If you experience this problem, you can help MATLAB break execution by including a drawnow, pause, or getframe function in your M-file, for example, within a large loop. Note that Ctrl+C might be less responsive if you started MATLAB with the -nodesktop option.

So I don't think any option exist. This happens with many matlab functions that are complex. Either we have to wait or don't use them!.

In my case I have used context for startActivity, after changing that with ActivityName.this . it solves. I'm using method from util class so this happens.

Hope it help some one.

If you are looking for a number that is bigger than all others:

Method 1:

float('inf')

Method 2:

import sys
max = sys.maxsize

If you are looking for a number that is smaller than all others:

Method 1:

float('-inf')

Method 2:

import sys
min = -sys.maxsize - 1

Method 1 works in both Python2 and Python3. Method 2 works in Python3. I have not tried Method 2 in Python2.

It sounds like you want something like the Perl chomp() function.

That's trivial to do in Python:

def chomp(s):
    return s[:-1] if s.endswith('\n') else s

... assuming you're using Python 2.6 or later. Otherwise just use the slightly more verbose:

def chomp(s):
    if s.endwith('\n'):
        return s[:-1]
    else:
        return s

If you want to remove all new lines from the end of a string (in the odd case where one might have multiple trailing newlines for some reason):

def chomps(s):
    return s.rstrip('\n')

Obviously you should never see such a string returned by any normal Python file object's readline() nor readlines() methods.

I've seen people blindly remove the last characters (using s[:-1] slicing) from the results of file readline() and similar functions. This is a bad idea because it can lead to an error on the last line of the file (in the case where a file ends with anything other than a newline).

At first you might be lulled into a false sense of security when blindly stripping final characters off lines you've read. If you use a normal text editor to create your test suite files you'll have a newline silently added to the end of the last line by most of them. To create a valid test file use code something like:

f = open('sometest.txt', 'w')
f.write('some text')
f.close()

... and then if you re-open that file and use the readline() or readlines() file methods on it you'll find that the text is read without the trailing newline.

This failure to account for text files ending in non-newline characters has plagued many UNIX utilities and scripting languages for many years. It's a stupid corner base bug that creeps into code just often enough to be a pest but not often enough for people to learn from it. We could argue that "text" files without the ultimate newline are "corrupt" or non-standard; and that may be valid for some programming specifications.

However, it's all too easy to ignore corner cases in our coding and have that ignorance bite people who are depending on your code later. As my wife says: when it comes to programming ... practice safe hex!

In my case it was an issue of the PHP version.

The .phar file I was using was not compatible with PHP 5.3.9. Switching interpreter to PHP 7 did fix it.

try this

Using WebClient.UploadString or WebClient.UploadData you can POST data to the server easily. I’ll show an example using UploadData, since UploadString is used in the same manner as DownloadString.

byte[] bret = client.UploadData("http://www.website.com/post.php", "POST",
                System.Text.Encoding.ASCII.GetBytes("field1=value1&field2=value2") );

The sort package provides the building blocks if your slice is sorted or you are willing to sort it.

input := []string{"bird", "apple", "ocean", "fork", "anchor"}
sort.Strings(input)

fmt.Println(contains(input, "apple")) // true
fmt.Println(contains(input, "grow"))  // false

...

func contains(s []string, searchterm string) bool {
    i := sort.SearchStrings(s, searchterm)
    return i < len(s) && s[i] == searchterm
}

SearchString promises to return the index to insert x if x is not present (it could be len(a)), so a check of that reveals whether the string is contained the sorted slice.

We can do something like this

DateTime date_temp_from = DateTime.Parse(from.Value); //from.value" is input by user (dd/MM/yyyy)
DateTime date_temp_to = DateTime.Parse(to.Value); //to.value" is input by user (dd/MM/yyyy)

string date_from = date_temp_from.ToString("yyyy/MM/dd HH:mm");
string date_to = date_temp_to.ToString("yyyy/MM/dd HH:mm");

Thank you

There's no direct equivalent of "friend" - the closest that's available (and it isn't very close) is InternalsVisibleTo. I've only ever used this attribute for testing - where it's very handy!

[assembly: InternalsVisibleTo("OtherAssembly")]

I have a same problem with google/google-api-php-client v2.0.0-RC7 and after search for 1 hours, i solved this problem using json_encode like this:

    if ($client->isAccessTokenExpired()) {
        $newToken = json_decode(json_encode($client->getAccessToken()));
        $client->refreshToken($newToken->refresh_token);
        file_put_contents(storage_path('app/client_id.txt'), json_encode($client->getAccessToken()));
    }

you can use this trick to run tomcat using cmd and directly by tomcat bin folder.

1. set the path of jdk.

2.

To set path. go to Desktop and right click on computer icon. Click the Properties

go to Advance System Settings.

then Click Advance to Environment variables.

Click new and set path AS,

in the column Variable name=JAVA_HOME

Variable Value=C:\Program Files\Java\jdk1.6.0_19

Click ok ok.

now path is stetted.

3.

Go to tomcat folder where you installed the tomcat. go to bin folder. there are two window batch files.

1.Startup

2.Shutdown.

By using cmd if you installed the tomcate in D Drive

type on cmd screen

1. D:

2. Cd tomcat\bin then type Startup.

4. By clicking them you can start and stop the tomcat.

5.

Final step.

if you start and want to check it.

open a Browser in URL bar type.

**HTTP://localhost:8080/**

Examples

Given the string foobarbarfoo:

bar(?=bar)     finds the 1st bar ("bar" which has "bar" after it)
bar(?!bar)     finds the 2nd bar ("bar" which does not have "bar" after it)
(?<=foo)bar    finds the 1st bar ("bar" which has "foo" before it)
(?<!foo)bar    finds the 2nd bar ("bar" which does not have "foo" before it)

You can also combine them:

(?<=foo)bar(?=bar)    finds the 1st bar ("bar" with "foo" before it and "bar" after it)

Definitions

Look ahead positive (?=)

Find expression A where expression B follows:

A(?=B)

Look ahead negative (?!)

Find expression A where expression B does not follow:

A(?!B)

Look behind positive (?<=)

Find expression A where expression B precedes:

(?<=B)A

Look behind negative (?<!)

Find expression A where expression B does not precede:

(?<!B)A

Atomic groups (?>)

An atomic group exits a group and throws away alternative patterns after the first matched pattern inside the group (backtracking is disabled).

• (?>foo|foot)s applied to foots will match its 1st alternative foo, then fail as s does not immediately follow, and stop as backtracking is disabled

A non-atomic group will allow backtracking; if subsequent matching ahead fails, it will backtrack and use alternative patterns until a match for the entire expression is found or all possibilities are exhausted.

• (foo|foot)s applied to foots will:

  1. match its 1st alternative foo, then fail as s does not immediately follow in foots, and backtrack to its 2nd alternative;
  2. match its 2nd alternative foot, then succeed as s immediately follows in foots, and stop.

I had also faced same error when i was trying to call bootstrap modal from jquery. But this happens because we are using bootstrap modal and for this we need to attach one cdn bootstrap.min.js which is

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Hope this will help as I missed that when i was trying to call bootstrap modal from jQuery using

$('#button').on('click',function(){ $('#myModal').modal(); });

myModal is the id of Bootstrap modal and you have to give a click event to a button when you call click that button a pop up modal will be displayed.

I think it's a historical thing - if a package is introduced as an addition to an existing JRE, it comes in as javax. If it's first introduced as part of a JRE (like NIO was, I believe) then it comes in as java. Not sure why the new date and time API will end up as javax following this logic though... unless it will also be available separately as a library to work with earlier versions (which would be useful). Note from many years later: it actually ended up being in java after all.

I believe there are restrictions on the java package - I think classloaders are set up to only allow classes within java.* to be loaded from rt.jar or something similar. (There's certainly a check in ClassLoader.preDefineClass.)

EDIT: While an official explanation (the search orbfish suggested didn't yield one in the first page or so) is no doubt about "core" vs "extension", I still suspect that in many cases the decision for any particular package has an historical reason behind it too. Is java.beans really that "core" to Java, for example?

One possible issue I see is you set your JSON unconventionally within an array/list object. I would recommend using JSON in its most accepted form, i.e.:

test_json = { "a": 1, "b": 2}

Once you do this, adding a json element only involves the following line:

test_json["c"] = 3

This will result in:

{'a': 1, 'b': 2, 'c': 3}

Afterwards, you can add that json back into an array or a list of that is desired.

I know this is an older post, but I'm leaving this for whomever else comes looking in the future.

You can't format line breaks into an option; however, you can use the title attibute to give a mouse-over tooltip to give the full info. Use a short descriptor in the option text and give the full skinny in the title.

<option value="1" title="This is my lengthy explanation of what this selection really means, so since you only see 1 on the drop down list you really know that you're opting to elect me as King of Willywarts!  Always be sure to read the fine print!">1</option>

If you have a lot of these to check you might want to store a list of the mappings and just loop over that, instead of having a bunch of if/else statements. Something like:

var CODE_TO_LOCATION = {
  'ST1': 'stoke central',
  'ST2': 'stoke north',
  // ...
};

function getLocation(text) {
  for (var code in CODE_TO_LOCATION) {
    if (text.indexOf(code) != -1) {
      return CODE_TO_LOCATION[code];
    }
  }
  return null;
}

This way you can easily add more code/location mappings. And if you want to handle more than one location you could just build up an array of locations in the function instead of just returning the first one you find.

I could not get the angular-cli to go away. I FINALLY figured out a way to find it on my windows machine. If you have Cygwin installed or you are running linux or mac you can run which ng and it will give you the directory the command is running from. In my case it was running from /c/Users/myuser/AppData/Roaming/npm/ng

You can do it using old DirectShow functionality.

This answer teaches you how to create QuartzTypeLib.dll:

1. Run tlbimp tool (in your case path will be different):

2. Run TlbImp.exe %windir%\system32\quartz.dll /out:QuartzTypeLib.dll

Alternatively, this project contains the library interop.QuartzTypeLib.dll, which is basically the same thing as steps 1. and 2. The following steps teach how to use this library:

3. Add generated QuartzTypeLib.dll as a COM-reference to your project (click right mouse button on the project name in "Solution Explorer", then select "Add" menu item and then "Reference")

4. In your Project, expand the "References", find the QuartzTypeLib reference. Right click it and select properties, and change "Embed Interop Types" to false. (Otherwise you won't be able to use the FilgraphManager class in your project (and probably a couple of other ones)).

5. In Project Settings, in the Build tab, I had to disable the Prefer 32-bit flag, Otherwise I would get this Exception: System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x80040266

6. Use this class to play your favorite MP3 file:

   using QuartzTypeLib;
   
   public sealed class DirectShowPlayer
   {
       private FilgraphManager FilterGraph;
   
       public void Play(string path)
       {
           FilgraphManager = new FilgraphManager();
           FilterGraph.RenderFile(path);
           FilterGraph.Run();
       }
   
       public void Stop()
       {
           FilterGraph?.Stop();
       }
   }
   

PS: TlbImp.exe can be found here: "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin", or in "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.2 Tools"

I would prefer a callback solution: Working fiddle here: http://jsfiddle.net/canCu/

function myFunction(value1,value2,value3, callback) {

    value2 = 'somevalue2'; //to return
    value3 = 'somevalue3'; //to return

    callback( value2, value3 );

}

var value1 = 1;
var value2 = 2;
var value3 = 3;

myFunction(value1,value2,value3, function(value2, value3){
    if (value2 && value3) {
        //Do some stuff
        alert( value2 + '-' + value3 );
    }    
});

The shortcut is: CTRL+_

One thing to note, if you are using a freestyle job, you won't be able to access build parameters or the Jenkins JVM's environment UNLESS you are using System Groovy Script build steps. I spent hours googling and researching before gathering enough clues to figure that out.

Not sure how efficient this might be in terms of performance, but this is what I use using array destructuring to keep everything nice and short:

const shareElements = (arr1, arr2) => {
  const typeArr = [...arr1, ...arr2]
  const typeSet = new Set(typeArr)
  return typeArr.length > typeSet.size
}

Since sets cannot have duplicate elements while arrays can, combining both input arrays, converting it to a set, and comparing the set size and array length would tell you if they share any elements.

My 2 cents on Excel 2016:

1. open the xls file with Notepad++
2. Search for DPB= and replace it with DPx=
3. Save the file
4. Open the file, open the VB Editor, open modules will not work (error 40230)
5. Save the file as xlsm
6. It works

Try the Apache Commons HttpClient library instead of trying to roll your own: http://hc.apache.org/httpclient-3.x/index.html

From their sample code:

  HttpClient httpclient = new HttpClient();
  httpclient.getHostConfiguration().setProxy("myproxyhost", 8080);

  /* Optional if authentication is required.
  httpclient.getState().setProxyCredentials("my-proxy-realm", " myproxyhost",
   new UsernamePasswordCredentials("my-proxy-username", "my-proxy-password"));
  */

  PostMethod post = new PostMethod("https://someurl");
  NameValuePair[] data = {
     new NameValuePair("user", "joe"),
     new NameValuePair("password", "bloggs")
  };
  post.setRequestBody(data);
  // execute method and handle any error responses.
  // ...
  InputStream in = post.getResponseBodyAsStream();
  // handle response.


  /* Example for a GET reqeust
  GetMethod httpget = new GetMethod("https://someurl");
  try { 
    httpclient.executeMethod(httpget);
    System.out.println(httpget.getStatusLine());
  } finally {
    httpget.releaseConnection();
  }
  */

Fancy way to put @rdhs answer in a function:

Function arrayZero(size As Integer)
  arrayZero = Evaluate("=IF(ISERROR(Transpose(A1:A" & size & ")), 0, 0)")
End Function

And use like this:

myArray = arrayZero(15)

git checkout {SHA1} -- filename

this command get the copied file from specific commit.

Give full path as input. Avoid relative paths.

 return File.Exists(FinalPath);

I always use READ UNCOMMITTED now. It's fast with the least issues. When using other isolations you will almost always come across some Blocking issues.

As long as you use Auto Increment fields and pay a little more attention to inserts then your fine, and you can say goodbye to blocking issues.

You can make errors with READ UNCOMMITED but to be honest, it is very easy make sure your inserts are full proof. Inserts/Updates which use the results from a select are only thing you need to watch out for. (Use READ COMMITTED here, or ensure that dirty reads aren't going to cause a problem)

So go the Dirty Reads (Specially for big reports), your software will run smoother...

In C++/CLI, a handle is a pointer to an object located on the GC heap. Creating an object on the (unmanaged) C++ heap is achieved using new and the result of a new expression is a "normal" pointer. A managed object is allocated on the GC (managed) heap with a gcnew expression. The result will be a handle. You can't do pointer arithmetic on handles. You don't free handles. The GC will take care of them. Also, the GC is free to relocate objects on the managed heap and update the handles to point to the new locations while the program is running.

You can use tableToExcel.js to export table in excel file.

This works in a following way :

1). Include this CDN in your project/file

<script src="https://cdn.jsdelivr.net/gh/linways/[email protected]/dist/tableToExcel.js"></script>

2). Either Using JavaScript:

<button id="btnExport" onclick="exportReportToExcel(this)">EXPORT REPORT</button>

function exportReportToExcel() {
  let table = document.getElementsByTagName("table"); // you can use document.getElementById('tableId') as well by providing id to the table tag
  TableToExcel.convert(table[0], { // html code may contain multiple tables so here we are refering to 1st table tag
    name: `export.xlsx`, // fileName you could use any name
    sheet: {
      name: 'Sheet 1' // sheetName
    }
  });
}

3). Or by Using Jquery

<button id="btnExport">EXPORT REPORT</button>

$(document).ready(function(){
    $("#btnExport").click(function() {
        let table = document.getElementsByTagName("table");
        TableToExcel.convert(table[0], { // html code may contain multiple tables so here we are refering to 1st table tag
           name: `export.xlsx`, // fileName you could use any name
           sheet: {
              name: 'Sheet 1' // sheetName
           }
        });
    });
});

Hope this will help someone :-)

The data.table package has a function 'as.ITime', which can do this efficiently use below:

library(data.table)
x <- "2012-03-07 03:06:49 CET"
as.IDate(x) # Output is "2012-03-07"
as.ITime(x) # Output is "03:06:49"

UPDATE Orders Order
SET Order.Quantity =  Order.Quantity - 1
WHERE SomeCondition(Order)

As far as I know there is no build-in support for INSERT-OR-UPDATE in SQL. I suggest to create a stored procedure or use a conditional query to achiev this. Here you can find a collection of solutions for different databases.

You just have to define the property below inside the activity element in your AndroidManifest.xml file. It will restrict your orientation to portrait.

android:screenOrientation="portrait"

Example:

        <activity
            android:name="com.example.demo_spinner.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
        </activity>

if you want this to apply to the whole app define the property below inside the application tag like so:

        <application>
         android:screenOrientation="sensorPortrait"
        </application>

Additionaly, as per Eduard Luca's comment below, you can also use screenOrientation="sensorPortrait" if you want to enable rotation by 180 degrees.

From DimitriDushkin on GitHub:

import { browserHistory } from 'react-router';

/**
 * @param {Object} query
 */
export const addQuery = (query) => {
  const location = Object.assign({}, browserHistory.getCurrentLocation());

  Object.assign(location.query, query);
  // or simple replace location.query if you want to completely change params

  browserHistory.push(location);
};

/**
 * @param {...String} queryNames
 */
export const removeQuery = (...queryNames) => {
  const location = Object.assign({}, browserHistory.getCurrentLocation());
  queryNames.forEach(q => delete location.query[q]);
  browserHistory.push(location);
};

or

import { withRouter } from 'react-router';
import { addQuery, removeQuery } from '../../utils/utils-router';

function SomeComponent({ location }) {
  return <div style={{ backgroundColor: location.query.paintRed ? '#f00' : '#fff' }}>
    <button onClick={ () => addQuery({ paintRed: 1 })}>Paint red</button>
    <button onClick={ () => removeQuery('paintRed')}>Paint white</button>
  </div>;
}

export default withRouter(SomeComponent);

Pending Intent is an intent who provides all permission to other application to do a particular works. When the main activity is destroyed, Android OS takes back the permission from it.

You could use the copy() function :

// Will copy foo/test.php to bar/test.php
// overwritting it if necessary
copy('foo/test.php', 'bar/test.php');

Quoting a couple of relevant sentences from its manual page :

Makes a copy of the file source to dest.

If the destination file already exists, it will be overwritten.

Wikipedia never lets down:

http://en.wikipedia.org/wiki/Hash_map_(C%2B%2B)

You can use the the ResultSetMetaData (http://java.sun.com/javase/6/docs/api/java/sql/ResultSetMetaData.html) object for that, like this:

ResultSet rs = stmt.executeQuery("SELECT * FROM table");
ResultSetMetaData rsmd = rs.getMetaData();
String firstColumnName = rsmd.getColumnName(1);

^\+[1-9]{1}[0-9]{7,11}$ 

The Regular Expression ^\+[1-9]{1}[0-9]{7,11}$ fails for "+290 8000" and similar valid numbers that are shorter than 8 digits.

The longest numbers could be something like 3 digit country code, 3 digit area code, 8 digit subscriber number, making 14 digits.

The Selenium client bindings will try to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

  export PATH=$PATH:/path/to/geckodriver
  

• On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.

All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2 to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.

To use Marionette in your tests you will need to update your desired capabilities to use it.

Java :

As exception is clearly saying you need to download latest geckodriver.exe from here and set downloaded geckodriver.exe path where it's exists in your computer as system property with with variable webdriver.gecko.driver before initiating marionette driver and launching firefox as below :-

//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities); 

And for Selenium3 use as :-

WebDriver driver = new FirefoxDriver();

If you're still in trouble follow this link as well which would help you to solving your problem

.NET :

var driver = new FirefoxDriver(new FirefoxOptions());

Python :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox

Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true

JavaScript (Node.js) :

const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;

var capabilities = Capabilities.firefox();

// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

Using RemoteWebDriver

If you want to use RemoteWebDriver in any language, this will allow you to use Marionette in Selenium Grid.

Python:

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps

Java :

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

.NET

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();

// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.

You can download latest geckodriver executable to support latest firefox from here

Briefly:

1. Get the self signed certificate
2. Put it into some (e.g. ~/git-certs/cert.pem) file
3. Set git to trust this certificate using http.sslCAInfo parameter

In more details:

Get self signed certificate of remote server

Assuming, the server URL is repos.sample.com and you want to access it over port 443.

There are multiple options, how to get it.

Get certificate using openssl

$ openssl s_client -connect repos.sample.com:443

Catch the output into a file cert.pem and delete all but part between (and including) -BEGIN CERTIFICATE- and -END CERTIFICATE-

Content of resulting file ~/git-certs/cert.pem may look like this:

-----BEGIN CERTIFICATE-----

Get certificate using your web browser

I use Redmine with Git repositories and I access the same URL for web UI and for git command line access. This way, I had to add exception for that domain into my web browser.

Using Firefox, I went to Options -> Advanced -> Certificates -> View Certificates -> Servers, found there the selfsigned host, selected it and using Export button I got exactly the same file, as created using openssl.

Note: I was a bit surprised, there is no name of the authority visibly mentioned. This is fine.

Having the trusted certificate in dedicated file

Previous steps shall result in having the certificate in some file. It does not matter, what file it is as long as it is visible to your git when accessing that domain. I used ~/git-certs/cert.pem

Note: If you need more trusted selfsigned certificates, put them into the same file:

-----BEGIN CERTIFICATE-----
MIIDnzCCAocCBE/xnXAwDQYJKoZIhvcNAQEFBQAwgZMxCzAJBgNVBAYTAkRFMRUw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
AnOtHeRtRuStEdCeRtIfIcAtEgOeShErExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----

This shall work (but I tested it only with single certificate).

Configure git to trust this certificate

$ git config --global http.sslCAInfo /home/javl/git-certs/cert.pem

You may also try to do that system wide, using --system instead of --global.

And test it: You shall now be able communicating with your server without resorting to:

$ git config --global http.sslVerify false #NO NEED TO USE THIS

If you already set your git to ignorance of ssl certificates, unset it:

$ git config --global --unset http.sslVerify

and you may also check, that you did it all correctly, without spelling errors:

$ git config --global --list

what should list all variables, you have set globally. (I mispelled http to htt).

I use AJAX to do this. You have your partial with your typical twitter modal template html:

<div class="container">
  <!-- Modal -->
  <div class="modal fade" id="LocationNumberModal" role="dialog">

Then you have your controller method, I use JSON and have a custom class that rendors the view to a string. I do this so I can perform multiple ajax updates on the screen with one ajax call. Reference here: Example but you can use an PartialViewResult/ActionResult on return if you are just doing the one call. I will show it using JSON..

And the JSON Method in Controller:

public JsonResult LocationNumberModal(string partNumber = "")
{
  //Business Layer/DAL to get information
  return Json(new {
      LocationModal = ViewUtility.RenderRazorViewToString(this.ControllerContext, "LocationNumberModal.cshtml", new SomeModelObject())
    },
    JsonRequestBehavior.AllowGet
  );
}

And then, in the view using your modal: You can package the AJAX in your partial and call @{Html.RenderPartial... Or you can have a placeholder with a div:

<div id="LocationNumberModalContainer"></div>

then your ajax:

function LocationNumberModal() {
  var partNumber = "1234";

  var src = '@Url.Action("LocationNumberModal", "Home", new { area = "Part" })'
    + '?partNumber='' + partNumber; 

  $.ajax({
    type: "GET",
    url: src,
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function (data) {
      $("#LocationNumberModalContainer").html(data.LocationModal);
      $('#LocationNumberModal').modal('show');
    }
  });
};

Then the button to your modal:

<button type="button" id="GetLocBtn" class="btn btn-default" onclick="LocationNumberModal()">Get</button>

You can use ISO-8859-9 encoding:

iconv -f ISO-8859-9 Agreement.txt -t UTF-8 -o agreement.txt

Please try this code:

$("#YourSelect>option:selected").html()

Also register your created service in the Manifest and uses-permission as

<application ...>
   <service android:name=".MyBroadcastReceiver">
        <intent-filter>
            <action android:name="com.example.MyBroadcastReciver"/>
        </intent-filter>
   </service>
</application>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

and then in braod cast Reciever call your service

public class MyBroadcastReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Intent myIntent = new Intent(context, MyService.class);
        context.startService(myIntent);
    }
}

File filedel = new File("/storage/sdcard0/Baahubali.mp3");
boolean deleted1 = filedel.delete();

Or, Try This:

String del="/storage/sdcard0/Baahubali.mp3";
File filedel2 = new File(del);
boolean deleted1 = filedel2.delete();

I have experienced this problem in some projects with Xcode 9.3.1 and in my case the problem is due to some swift code that for some reason Xcode doesn't like. This problem is hard to solve because is difficult to find what file is causing the problem.

When I have this problem, I removing some files from the Xcode project (removing references) and I try to test if indexing works. My process to do so

1. Remove some files
2. Close Xcode
3. Open Xcode
4. If indexing finish try to rename some method if works probably the files you have removed they have something strange for Xcode.

In my case I had a class definition with a reactive extension in the same file and for some reason Xcode doesn't like it, I moved the reactive extension to another file and now the indexing works fine.

In the C standard, a standalone implementation doesn't have to provide all of the library functions that a hosted implementation has to provide. The C standard doesn't care about embedded, but vendors of embedded systems usually provide standalone implementations with whatever amount of libraries they're willing to provide.

C is a widely used general purpose high level programming language mainly intended for system programming.

Embedded C is an extension to C programming language that provides support for developing efficient programs for embedded devices.It is not a part of the C language

You can also refer to the articles below:

C# version:

Create a moderator class and inherit it from MarshalByRefObject:

class ProxyDomain : MarshalByRefObject
{
    public Assembly GetAssembly(string assemblyPath)
    {
        try
        {
            return Assembly.LoadFrom(assemblyPath);
        }
        catch (Exception ex)
        {

        }
    }
}

call from client site

ProxyDomain pd = new ProxyDomain();
Assembly assembly = pd.GetAssembly(assemblyFilePath);

So why don't you simply use a key-value literal?

var params = {
    'slide0001.html': 'Looking Ahead',
    'slide0002.html': 'Forecase',
    ...
};

return params['slide0001.html']; // returns: Looking Ahead

If your are in Visual Studio 2012 or later this has an additional setting 'SDL checks' Under Property Pages -> C/C++ -> General

Additional Security Development Lifecycle (SDL) recommended checks; includes enabling additional secure code generation features and extra security-relevant warnings as errors.

It defaults to YES - For a reason, I.E you should use the secure version of the strncpy. If you change this to NO you will not get a error when using the insecure version.

SDL checks in vs2012 and later

You can just do:

echo $xml['token'];

Firstly, understand that DateTime objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime objects without formatting them.

To compare an input date with DateTime.Now, you need to first parse the input into a date and then compare just the Year/Month/Day portions:

DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
    throw new ArgumentException("Input string not in the correct format.");

if(inputDate.Date == DateTime.Now.Date) {
    // Same date!
}

.dex file

Compiled Android application code file.

Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created automatically by Android, by translating the compiled applications written in the Java programming language.

Since you are having trouble adjusting the height you might be able to use this. http://jsfiddle.net/uf9bx/1/

img{
width: 100%;
height: 100%;
max-height: 300px;
}

I'm not sure exactly what size or location you are putting your images but maybe this will help!

Not sure if MySQL has row_number function. If so you can use it to get the desired result. On SQL Server you can do something similar to:

CREATE TABLE p
(
 person NVARCHAR(10),
 gp INT,
 age INT
);
GO
INSERT  INTO p
VALUES  ('Bob', 1, 32);
INSERT  INTO p
VALUES  ('Jill', 1, 34);
INSERT  INTO p
VALUES  ('Shawn', 1, 42);
INSERT  INTO p
VALUES  ('Jake', 2, 29);
INSERT  INTO p
VALUES  ('Paul', 2, 36);
INSERT  INTO p
VALUES  ('Laura', 2, 39);
GO

SELECT  t.person, t.gp, t.age
FROM    (
         SELECT *,
                ROW_NUMBER() OVER (PARTITION BY gp ORDER BY age DESC) row
         FROM   p
        ) t
WHERE   t.row = 1;

Explicitly wait or conditional wait in this wait until given this condition.

WebDriverWait wait = new WebDriverWait(wb, 60);
wait.until(ExpectedConditions.elementToBeClickable(By.name("value")));

This will wait for every web element for 60 seconds.

Use implicitly wait for wait of every element on page till that given time.

driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

This will wait for every web element for 60 seconds.

You need to use an explicit color value (e.g. #000 or blue) for the color-property. none is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active, too.

Just try this in Javascript:

 $previous = "javascript:history.go(-1)";

Or you can try it in PHP:

if(isset($_SERVER['HTTP_REFERER'])) {
    $previous = $_SERVER['HTTP_REFERER'];
}

My initial theory about the difference was that library loads the packages whether it is already loaded or not, i.e. it might reload an already loaded package, while require just checks that it is loaded, or loads it if it isn't (thus the use in functions that rely on a certain package). The documentation refutes this, however, and explicitly states that neither function will reload an already loaded package.

Here is how i resolved this:

1 - create a Field Variable like: private Menu mMenuItem;

2 - override the method invalidateOptionsMenu():

@Override
public void invalidateOptionsMenu() {
    super.invalidateOptionsMenu();
}

3 - call the method invalidateOptionsMenu() in your onCreate()

4 - add mMenuItem = menu in your onCreateOptionsMenu(Menu menu) like this:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.webview_menu, menu);
    mMenuItem = menu;
    return super.onCreateOptionsMenu(menu);
}

5 - in the method onOptionsItemSelected(MenuItem item) change the icon you want like this:

 @Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()){

        case R.id.R.id.action_settings:
            mMenuItem.getItem(0).setIcon(R.drawable.ic_launcher); // to change the fav icon
            //Toast.makeText(this, " " + mMenuItem.getItem(0).getTitle(), Toast.LENGTH_SHORT).show(); <<--- this to check if the item in the index 0 is the one you are looking for
            return true;
    }
    return super.onOptionsItemSelected(item);
}

Why not use the DateTime module to do the dirty work for you? It's easy to write and remember!

use strict;
use warnings;
use DateTime;

my $dt   = DateTime->now;   # Stores current date and time as datetime object
my $date = $dt->ymd;   # Retrieves date as a string in 'yyyy-mm-dd' format
my $time = $dt->hms;   # Retrieves time as a string in 'hh:mm:ss' format

my $wanted = "$date $time";   # creates 'yyyy-mm-dd hh:mm:ss' string
print $wanted;

Once you know what's going on, you can get rid of the temps and save a few lines of code:

use strict;
use warnings;
use DateTime;

my $dt = DateTime->now;
print join ' ', $dt->ymd, $dt->hms;

android:versionCode — An integer value that represents the version of the application code, relative to other versions.

The value is an integer so that other applications can programmatically evaluate it, for example to check an upgrade or downgrade relationship. You can set the value to any integer you want, however you should make sure that each successive release of your application uses a greater value. The system does not enforce this behavior, but increasing the value with successive releases is normative.

android:versionName — A string value that represents the release version of the application code, as it should be shown to users.

The value is a string so that you can describe the application version as a .. string, or as any other type of absolute or relative version identifier.

As with android:versionCode, the system does not use this value for any internal purpose, other than to enable applications to display it to users. Publishing services may also extract the android:versionName value for display to users.

Typically, you would release the first version of your application with versionCode set to 1, then monotonically increase the value with each release, regardless whether the release constitutes a major or minor release. This means that the android:versionCode value does not necessarily have a strong resemblance to the application release version that is visible to the user (see android:versionName, below). Applications and publishing services should not display this version value to users.

This will do it:

var json = (function () {
    var json = null;
    $.ajax({
        'async': false,
        'global': false,
        'url': my_url,
        'dataType': "json",
        'success': function (data) {
            json = data;
        }
    });
    return json;
})(); 

The main issue being that $.getJSON will run asynchronously, thus your Javascript will progress past the expression which invokes it even before its success callback fires, so there are no guarantees that your variable will capture any data.

Note in particular the 'async': false option in the above ajax call. The manual says:

By default, all requests are sent asynchronous (i.e. this is set to true by default). If you need synchronous requests, set this option to false. Note that synchronous requests may temporarily lock the browser, disabling any actions while the request is active.

With selectable date ranges you might want to use something like this. My solution prevents selecting #from_date bigger than #to_date and changes #to_date startDate every time when user selects new date in #from_date box:

http://bootply.com/74352

JS file:

var startDate = new Date('01/01/2012');
var FromEndDate = new Date();
var ToEndDate = new Date();

ToEndDate.setDate(ToEndDate.getDate()+365);

$('.from_date').datepicker({

    weekStart: 1,
    startDate: '01/01/2012',
    endDate: FromEndDate, 
    autoclose: true
})
    .on('changeDate', function(selected){
        startDate = new Date(selected.date.valueOf());
        startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
        $('.to_date').datepicker('setStartDate', startDate);
    }); 
$('.to_date')
    .datepicker({

        weekStart: 1,
        startDate: startDate,
        endDate: ToEndDate,
        autoclose: true
    })
    .on('changeDate', function(selected){
        FromEndDate = new Date(selected.date.valueOf());
        FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
        $('.from_date').datepicker('setEndDate', FromEndDate);
    });

HTML:

<input class="from_date" placeholder="Select start date" contenteditable="false" type="text">
<input class="to_date" placeholder="Select end date" contenteditable="false" type="text" 

And do not forget to include bootstrap datepicker.js and .css files aswell.

Datetime is a datatype.

Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

For more information:

http://www.sqlteam.com/article/timestamps-vs-datetime-data-types

def fun():
    print(('{0} Here is a really long '
           'sentence with {1}').format(3, 5))

Adjacent string literals are concatenated at compile time, just as in C. http://docs.python.org/reference/lexical_analysis.html#string-literal-concatenation is a good place to start for more info.

Update for 2018. You can use:

global $product;
echo wc_display_product_attributes( $product );

To customise the output, copy plugins/woocommerce/templates/single-product/product-attributes.php to themes/theme-child/woocommerce/single-product/product-attributes.php and modify that.

I've seen several approaches to working around the bug, and I ran some timing tests to see what works for speed (http://jsfiddle.net/5dwwy/)

Approaches:

1. Direct assignment

   In this approach, the razor syntax is directly assigned to the variable. This is what throws the error. As a baseline, the JavaScript speed test simply does a straight assignment of a number to a variable.

2. Pass through `Number` constructor

   In this approach, we wrap the razor syntax in a call to the `Number` constructor, as in `Number(@ViewBag.Value)`.

3. ParseInt

   In this approach, the razor syntax is put inside quotes and passed to the `parseInt` function.

4. Value-returning function

   In this approach, a function is created that simply takes the razor syntax as a parameter and returns it.

5. Type-checking function

   In this approach, the function performs some basic type checking (looking for null, basically) and returns the value if it isn't null.

Procedure:

Using each approach mentioned above, a for-loop repeats each function call 10M times, getting the total time for the entire loop. Then, that for-loop is repeated 30 times to obtain an average time per 10M actions. These times were then compared to each other to determine which actions were faster than others.

Note that since it is JavaScript running, the actual numbers other people receive will differ, but the importance is not in the actual number, but how the numbers compare to the other numbers.

Results:

Using the Direct assignment approach, the average time to process 10M assignments was 98.033ms. Using the Number constructor yielded 1554.93ms per 10M. Similarly, the parseInt method took 1404.27ms. The two function calls took 97.5ms for the simple function and 101.4ms for the more complex function.

Conclusions:

The cleanest code to understand is the Direct assignment. However, because of the bug in Visual Studio, this reports an error and could cause issues with Intellisense and give a vague sense of being wrong.

The fastest code was the simple function call, but only by a slim margin. Since I didn't do further analysis, I do not know if this difference has a statistical significance. The type-checking function was also very fast, only slightly slower than a direct assignment, and includes the possibility that the variable may be null. It's not really practical, though, because even the basic function will return undefined if the parameter is undefined (null in razor syntax).

Parsing the razor value as an int and running it through the constructor were extremely slow, on the order of 15x slower than a direct assignment. Most likely the Number constructor is actually internally calling parseInt, which would explain why it takes longer than a simple parseInt. However, they do have the advantage of being more meaningful, without requiring an externally-defined (ie somewhere else in the file or application) function to execute, with the Number constructor actually minimizing the visible casting of an integer to a string.

Bottom line, these numbers were generated running through 10M iterations. On a single item, the speed is incalculably small. For most, simply running it through the Number constructor might be the most readable code, despite being the slowest.

Seems you need to use JToggleButton :

JToggleButton tb = new JToggleButton("push me");
tb.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        JToggleButton btn =  (JToggleButton) e.getSource();
        btn.setText(btn.isSelected() ? "pushed" : "push me");
    }
});

you can run flutter clean command

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

Manual method works well with import android.util.Base64, but be sure to set Base64.NO_WRAP on calling encode:

String basicAuth = "Basic " + new String(Base64.encode("user:pass".getBytes(),Base64.NO_WRAP ));
connection.setRequestProperty ("Authorization", basicAuth);

You can try this:

"ab c d efg hi ".split.map(&:strip)

in order to get this:

["ab, "c", "d", "efg", "hi"]

or if you want a single string, just use:

"ab c d efg hi ".split.join

I had a same issue. This solution works for me from WebDriverDoku:

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("someid")));

http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp

Yet another option:

>>> import time
>>> time.strftime("%Y-%m-%d %H:%M:%S")
'2011-11-03 11:31:28'

By default this uses local time, if you need UTC you can use the following:

>>> time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime())
'2011-11-03 18:32:20'

I had a great deal of trouble with this. I just wanted to:

thisBill.IntervalCount = jPaidCountSpinner.getValue();

Where IntervalCount is a Long, and the JSpinner was set to return a Long. Eventually I had to write this function:

    public static final Long getLong(Object obj) throws IllegalArgumentException {
    Long rv;

    if((obj.getClass() == Integer.class) || (obj.getClass() == Long.class) || (obj.getClass() == Double.class)) {
        rv = Long.parseLong(obj.toString());
    }
    else if((obj.getClass() == int.class) || (obj.getClass() == long.class) || (obj.getClass() == double.class)) {
        rv = (Long) obj;
    }
    else if(obj.getClass() == String.class) {
        rv = Long.parseLong(obj.toString());
    }
    else {
        throw new IllegalArgumentException("getLong: type " + obj.getClass() + " = \"" + obj.toString() + "\" unaccounted for");
    }

    return rv;
}

which seems to do the trick. No amount of simple casting, none of the above solutions worked for me. Very frustrating.

open div then put

close div

You don't need to override onBackPressed() - it's already defined as the action that your activity will do by default when the user pressed the back button. So just call onBackPressed() whenever you want to "programatically press" the back button.

That would only result to finish() being called, though ;)

I think you're confused with what the back button does. By default, it's just a call to finish(), so it just exits the current activity. If you have something behind that activity, that screen will show.

What you can do is when launching your activity from the Login, add a CLEAR_TOP flag so the login activity won't be there when you exit yours.

With Vagrant now you can have Docker as a provider. http://docs.vagrantup.com/v2/docker/. Docker provider can be used instead of VirtualBox or VMware.

Please note that you can also use Docker for provisioning with Vagrant. This is very different than using Docker as a provider. http://docs.vagrantup.com/v2/provisioning/docker.html

This means you can replace Chef or Puppet with Docker. You can use combinations like Docker as provider (VM) with Chef as provisioner. Or you can use VirtualBox as provider and Docker as provisioner.

1. Pick a random number between [0, x), where x is the number of different symbols. Hopefully the choice is uniformly chosen and not predictable :-)

2. Now choose the symbol representing x.

3. Profit!

I would start reading up Pseudorandomness and then some common Pseudo-random number generators. Of course, your language hopefully already has a suitable "random" function :-)

This is an API issue, you won't get this error if using Postman/Fielder to send HTTP requests to API. In case of browsers, for security purpose, they always send OPTIONS request/preflight to API before sending the actual requests (GET/POST/PUT/DELETE). Therefore, in case, the request method is OPTION, not only you need to add "Authorization" into "Access-Control-Allow-Headers", but you need to add "OPTIONS" into "Access-Control-allow-methods" as well. This was how I fixed:

if (context.Request.Method == "OPTIONS")
        {
            context.Response.Headers.Add("Access-Control-Allow-Origin", new[] { (string)context.Request.Headers["Origin"] });
            context.Response.Headers.Add("Access-Control-Allow-Headers", new[] { "Origin, X-Requested-With, Content-Type, Accept, Authorization" });
            context.Response.Headers.Add("Access-Control-Allow-Methods", new[] { "GET, POST, PUT, DELETE, OPTIONS" });
            context.Response.Headers.Add("Access-Control-Allow-Credentials", new[] { "true" });

        }

var firstFiveItems = myList.Take(5);

Or to slice:

var secondFiveItems = myList.Skip(5).Take(5);

And of course often it's convenient to get the first five items according to some kind of order:

var firstFiveArrivals = myList.OrderBy(i => i.ArrivalTime).Take(5);

I have faced the same problem while update Android studio from 2.0 to 2.1 in my Windows 8 machine.

I found a solution for that.Please use the following steps.

1. Download the android NDK for windows from https://developer.android.com/ndk/downloads/index.html.
2. Extract the same and copy the "toolchain" folder from the bundle.
3. Paste the folder under installed NDK folder under C:\android-sdk-win\ndk-bundle.[Installed the path may vary based on your installation]
4. Restart android studio.

This is happening because Android studio won't gets full NDK update in the stable channel. If you are not using NDK for your project development you can simply remove the NDK folder from your SDK directory.

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.

location / {
    proxy_pass                      http://example.com;
    proxy_set_header                Host example.com;
    proxy_set_header                HTTP_Country-Code $geoip_country_code;
    proxy_pass_request_headers      on;
}

And now it's passed to the proxy backend.

In short, functools.wraps is just a regular function. Let's consider this official example. With the help of the source code, we can see more details about the implementation and the running steps as follows:

1. wraps(f) returns an object, say O1. It is an object of the class Partial
2. The next step is @O1... which is the decorator notation in python. It means

wrapper=O1.__call__(wrapper)

Checking the implementation of __call__, we see that after this step, (the left hand side )wrapper becomes the object resulted by self.func(*self.args, *args, **newkeywords) Checking the creation of O1 in __new__, we know self.func is the function update_wrapper. It uses the parameter *args, the right hand side wrapper, as its 1st parameter. Checking the last step of update_wrapper, one can see the right hand side wrapper is returned, with some of attributes modified as needed.

Use this code in your .cshtml file.

-u option will display including object files if they are added during compilation.

So, to overcome that additionally you may use like this.

svn status -u | grep -v '\?' 

I know the accepted answer is great but for anyone who is looking for a hover like feel you can use setTimeout on mouseover and save the handle in a map (of let's say list ids to setTimeout Handle). On mouseover clear the handle from setTimeout and delete it from the map

onMouseOver={() => this.onMouseOver(someId)}
onMouseOut={() => this.onMouseOut(someId)

And implement the map as follows:

onMouseOver(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = setTimeout(() => {
    scrollPreviewToComponentId(listId);
  }, 1000); // Replace 1000ms with any time you feel is good enough for your hover action
  this.hoverHandleMap[listId] = handle;
}

onMouseOut(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = this.hoverHandleMap[listId];
  clearTimeout(handle);
  delete this.hoverHandleMap[listId];
}

And the map is like so,

hoverHandleMap: { [listId: string]: NodeJS.Timeout } = {};

I prefer onMouseOver and onMouseOut because it also applies to all the children in the HTMLElement. If this is not required you may use onMouseEnter and onMouseLeave respectively.

Use forward slashes to specify the UNC Path:

open('//HOST/share/path/to/file')

(if your Python client code is also running under Windows)

Here is what I do on my projects in jupyter notebook,

import sys
sys.path.append("../") # go to parent dir
from customFunctions import *

Then, to affect changes in customFunctions.py,

%load_ext autoreload
%autoreload 2

It looks like you are willing to create a temporary Map, so I'd do it like this:

Map tmp = new HashMap(patch);
tmp.keySet().removeAll(target.keySet());
target.putAll(tmp);

Here, patch is the map that you are adding to the target map.

Thanks to Louis Wasserman, here's a version that takes advantage of the new methods in Java 8:

patch.forEach(target::putIfAbsent);

Hibernate's PostgreSQL dialect isn't very bright. It doesn't know about your per-SERIAL sequences, and is assuming there's a global database-wide sequence called "hibernate_sequence" that it can use.

(UPDATE: It appears that newer Hibernate versions may use the default per-table sequences when GenerationType.IDENTITY is specified. Test your version and use this instead of the below if it works for you.)

You need to change your mappings to explicitly specify each sequence. It's annoying, repetitive, and pointless.

@Entity
@Table(name = "JUDGEMENTS")
public class Judgement implements Serializable, Cloneable {

    private static final long serialVersionUID = -7049957706738879274L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="judgements_id_seq")
    @SequenceGenerator(name="judgements_id_seq", sequenceName="judgements_id_seq", allocationSize=1)
    @Column(name = "JUD_ID")
    private Long _judId;
...

The allocationSize=1 is quite important. If you omit it, Hibernate will blindly assume that the sequence is defined with INCREMENT 50 so when it gets a value from a sequence it can use that value and the 49 values below it as unique generated keys. If your database sequences increment by 1 - the default - then this will result in unique violations as Hibernate tries to re-use existing keys.

Note that getting one key at a time will result in an additional round trip per insert. As far as I can tell Hibernate isn't capable of using INSERT ... RETURNING to efficiently return generated keys, nor can it apparently use the JDBC generated keys interface. If you tell it to use a sequence, it'll call nextval to get the value then insert that explicitly, resulting in two round trips. To reduce the cost of that, you can set a greater increment on key sequences with lots of inserts , remembering to set it on the mapping and the underlying database sequence. That'll cause Hibernate to call nextval less frequently and cache blocks of keys to hand out as it goes.

I'm sure you can see from the above that I don't agree with the Hibernate design choices made here, at least from the perspective of using it with PostgreSQL. They should be using getGeneratedKeys or using INSERT ... RETURNING with DEFAULT for the key, letting the database take care of this without Hibernate having to trouble its self over the names of the sequences or explicit access to them.

BTW, if you're using Hibernate with Pg you'll possibly also want an oplock trigger for Pg to allow Hibernate's optimistic locking to interact safely with normal database locking. Without it or something like it your Hibernate updates will tend to clobber changes made via other regular SQL clients. Ask me how I know.
