You should be able to perform a select on the orders table, using a raw WHERE to find the max(id) in a subquery, like this:

 \DB::table('orders')->where('id', \DB::raw("(select max(`id`) from orders)"))->get();

If you want to use Eloquent (for example, so you can convert your response to an object) you will want to use whereRaw, because some functions such as toJSON or toArray will not work without using Eloquent models.

 $order = Order::whereRaw('id = (select max(`id`) from orders)')->get();

That, of course, requires that you have a model that extends Eloquent.

 class Order extends Eloquent {}

As mentioned in the comments, you don't need to use whereRaw, you can do the entire query using the query builder without raw SQL.

 // Using the Query Builder
 \DB::table('orders')->find(\DB::table('orders')->max('id'));

 // Using Eloquent
 $order = Order::find(\DB::table('orders')->max('id'));

(Note that if the id field is not unique, you will only get one row back - this is because find() will only return the first result from the SQL server.).

You should be using @RequestParam instead of @ModelAttribute, e.g.

@RequestMapping("/{someID}")
public @ResponseBody int getAttr(@PathVariable(value="someID") String id, 
                                 @RequestParam String someAttr) {
}

You can even omit @RequestParam altogether if you choose, and Spring will assume that's what it is:

@RequestMapping("/{someID}")
public @ResponseBody int getAttr(@PathVariable(value="someID") String id, 
                                 String someAttr) {
}

You could also use the store library which performs it for you with crossbrowser ability.

example :

// Store current user
store.set('user', { name:'Marcus' })

// Get current user
store.get('user')

// Remove current user
store.remove('user')

// Clear all keys
store.clearAll()

// Loop over all stored values
store.each(function(value, key) {
    console.log(key, '==', value)
})

While loop will take long time to delete all items if array has 100's of items. You can empty both controls and value properties of FormArray like below.

clearFormArray = (formArray: FormArray) => { formArray.controls = []; formArray.setValue([]); }

In my (I have LAMP installed) /etc/mysql/my.cnf file I found following, commented lines in [mysqld] section:

general_log_file        = /var/log/mysql/mysql.log
general_log             = 1

I had to open this file as superuser, with terminal:

sudo geany /etc/mysql/my.cnf

(I prefer to use Geany instead of gedit or VI, it doesn't matter)

I just uncommented them & save the file then restart MySQL with

sudo service MySQL restart

Run several queries, open the above file (/var/log/mysql/mysql.log) and the log was there :)

You can use literal quoting:

stmt := q'[insert into MY_TBL (Col) values('ER0002')]';

Documentation for literals can be found here.

Alternatively, you can use two quotes to denote a single quote:

stmt := 'insert into MY_TBL (Col) values(''ER0002'')';

The literal quoting mechanism with the Q syntax is more flexible and readable, IMO.

I have checked a variable if it is a boolean or not as below

console.log(isBoolean(this.myVariable));

Similarly we have

isNumber(this.myVariable);
isString(this.myvariable);

and so on.

If you give the label an ID, like this:

<label for="foo" id="foo_label">

Then this would work:

#foo_label { display: none;}

Your other options aren't really cross-browser friendly, unless javascript is an option. The CSS3 selector, not as widely supported looks like this:

[for="foo"] { display: none;}

Secure authentication is a broad topic. In a nutshell, as @jeremy-powell mentioned, always favour sending credentials over HTTPS instead of HTTP. It will take away a lot of security related headaches.

TSL/SSL certificates are pretty cheap these days. In fact if you don't want to spend money at all there is a free letsencrypt.org - automated Certificate Authority.

You can go one step further and use caddyserver.com which calls letsencrypt in the background.

Now, once we got HTTPS out of the way...

You shouldn't send login and password via POST payload or GET parameters. Use an Authorization header (Basic access authentication scheme) instead, which is constructed as follows:

• The username and password are combined into a string separated by a colon, e.g.: username:password
• The resulting string is encoded using the RFC2045-MIME variant of Base64, except not limited to 76 char/line.
• The authorization method and a space i.e. "Basic " is then put before the encoded string.

source: Wikipedia: Authorization header

It might seem a bit complicated, but it is not. There are plenty good libraries out there that will provide this functionality for you out of the box.

There are a few good reasons you should use an Authorization header

1. It is a standard
2. It is simple (after you learn how to use them)
3. It will allow you to login at the URL level, like this: https://user:[email protected]/login (Chrome, for example will automatically convert it into Authorization header)

IMPORTANT:
As pointed out by @zaph in his comment below, sending sensitive info as GET query is not good idea as it will most likely end up in server logs.

Try rejson-py which is relatively new since 2017. Look at this introduction.

from rejson import Client, Path

rj = Client(host='localhost', port=6379)

# Set the key `obj` to some object
obj = {
    'answer': 42,
    'arr': [None, True, 3.14],
    'truth': {
        'coord': 'out there'
    }
}
rj.jsonset('obj', Path.rootPath(), obj)

# Get something
print 'Is there anybody... {}?'.format(
    rj.jsonget('obj', Path('.truth.coord'))
)

# Delete something (or perhaps nothing), append something and pop it
rj.jsondel('obj', Path('.arr[0]'))
rj.jsonarrappend('obj', Path('.arr'), 'something')
print '{} popped!'.format(rj.jsonarrpop('obj', Path('.arr')))

# Update something else
rj.jsonset('obj', Path('.answer'), 2.17)

If you are using the ADT version 22, you need to check the android dependencies and android private libraries in the order&Export tab in the project build path

Update: This should probably be the accepted answer since maxElement appeared in Swift.

Use the almighty reduce:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, { max($0, $1) })

Similarly:

let numMin = nums.reduce(Int.max, { min($0, $1) })

reduce takes a first value that is the initial value for an internal accumulator variable, then applies the passed function (here, it's anonymous) to the accumulator and each element of the array successively, and stores the new value in the accumulator. The last accumulator value is then returned.

For IE8 or console support limited to console.log (no debug, trace, ...) you can do the following:

• If console OR console.log undefined: Create dummy functions for console functions (trace, debug, log, ...)

  window.console = { debug : function() {}, ...};

• Else if console.log is defined (IE8) AND console.debug (any other) is not defined: redirect all logging functions to console.log, this allows to keep those logs !

  window.console = { debug : window.console.log, ...};

Not sure about the assert support in various IE versions, but any suggestions are welcome.

The permament pool contains everything that is not your application data, but rather things required for the VM: typically it contains interned strings, the byte code of defined classes, but also other "not yours" pieces of data.

we can control the scrolling speed by using the scrollamount attribute,

Example:

<marquee scrollamount="30">scrolling fast</marquee>
<marquee scrollamount="2">scrolling slow</marquee>

note:if you specify the minimum number, the scrolling speed will be reduce vice versa

Well, different color notations is what you will have to learn.
Kuler gives you a better chance to find color and in multiple notations.
Hex is not different from RGB, FF = 255 and 00 = 0, but that's what you know. So in a way, you have to visualize it.
I use Hex, RGBA and RGB. Unless mass conversion is required, manually doing this will help you remember some odd 100 colors and their codes.
For mass conversion write some script like one given by Alarie. Have a blast with Colors.

Run this to find all instances of Xcode in your filesystem:

for i in find / -name Xcode -print; do echo $i; done

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

When you use a function ...

<p onclick="update_url('/en/step2');">Link</p>

<script>
function update_url(url) {
    history.pushState(null, null, url);
}
</script>

The equation below is a expression that tests if a point is within a given circle where xP & yP are the coordinates of the point, xC & yC are the coordinates of the center of the circle and R is the radius of that given circle.

If the above expression is true then the point is within the circle.

Below is a sample implementation in C#:

    public static bool IsWithinCircle(PointF pC, Point pP, Single fRadius){
        return Distance(pC, pP) <= fRadius;
    }

    public static Single Distance(PointF p1, PointF p2){
        Single dX = p1.X - p2.X;
        Single dY = p1.Y - p2.Y;
        Single multi = dX * dX + dY * dY;
        Single dist = (Single)Math.Round((Single)Math.Sqrt(multi), 3);

        return (Single)dist;
    }

The answer to this is very needed today because not everyone wants to use cURL to consume web services. Also PHP does allow for this using the following code

function get_info()
{
    $post_data = array(
        'test' => 'foobar',
        'okay' => 'yes',
        'number' => 2
    );

    // Send a request to example.com
    $result = $this->post_request('http://www.example.com/', $post_data);

    if ($result['status'] == 'ok'){

        // Print headers
        echo $result['header'];

        echo '<hr />';

        // print the result of the whole request:
        echo $result['content'];

    }
    else {
        echo 'A error occured: ' . $result['error'];
    }

}

function post_request($url, $data, $referer='') {

    // Convert the data array into URL Parameters like a=b&foo=bar etc.
    $data = http_build_query($data);

    // parse the given URL
    $url = parse_url($url);

    if ($url['scheme'] != 'http') {
        die('Error: Only HTTP request are supported !');
    }

    // extract host and path:
    $host = $url['host'];
    $path = $url['path'];

    // open a socket connection on port 80 - timeout: 30 sec
    $fp = fsockopen($host, 80, $errno, $errstr, 30);

    if ($fp){

        // send the request headers:
        fputs($fp, "POST $path HTTP/1.1\r\n");
        fputs($fp, "Host: $host\r\n");

        if ($referer != '')
            fputs($fp, "Referer: $referer\r\n");

        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: ". strlen($data) ."\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $data);

        $result = '';
        while(!feof($fp)) {
            // receive the results of the request
            $result .= fgets($fp, 128);
        }
    }
    else {
        return array(
            'status' => 'err',
            'error' => "$errstr ($errno)"
        );
    }

    // close the socket connection:
    fclose($fp);

    // split the result header from the content
    $result = explode("\r\n\r\n", $result, 2);

    $header = isset($result[0]) ? $result[0] : '';
    $content = isset($result[1]) ? $result[1] : '';

    // return as structured array:
    return array(
        'status' => 'ok',
        'header' => $header,
        'content' => $content);

}

Here's a nice easy way I found:

h <- hist(g, breaks = 10, density = 10,
          col = "lightgray", xlab = "Accuracy", main = "Overall") 
xfit <- seq(min(g), max(g), length = 40) 
yfit <- dnorm(xfit, mean = mean(g), sd = sd(g)) 
yfit <- yfit * diff(h$mids[1:2]) * length(g) 

lines(xfit, yfit, col = "black", lwd = 2)

For android app .Press Ctrl+M select debug js remotely it will open a new window in chrome with url http://localhost:8081/debugger-ui. You can now debug the app in chrome browser

As for the order preservation, see this ActiveMQ page. In short: order is preserved for single consumers, but with multiple consumers order of delivery is not guaranteed.

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

I'd do it this way:

grid1.DataContext = dt.AsEnumerable().Where(x => x < 10).AsEnumerable().CopyToDataTable().AsDataView();

and do whatever query i want between the two AsEnumerable(). If you don't need space for query, you can just do directly this:

grid1.DataContext = dt.AsDataView();

I believe this should also do the job too:

background-size: contain;

It specifies that the image should be resized to fit within the element without losing it's aspect ratio.

I like this one, that hasn't been mentioned above.

require 'pathname'

Pathname.new('/my/dir').children.each do |path|
    puts path
end

The benefit is that you get a Pathname object instead of a string, that you can do useful stuff with and traverse further.

Try this, it should work for what you need:

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});

This is something I wrote a few minutes ago just messing around. Hope it helps!

public class Main {

public static void main(String[] args) {

    ArrayList<Integer> powers = new ArrayList<Integer>();
    ArrayList<Integer> binaryStore = new ArrayList<Integer>();

    powers.add(128);
    powers.add(64);
    powers.add(32);
    powers.add(16);
    powers.add(8);
    powers.add(4);
    powers.add(2);
    powers.add(1);

    Scanner sc = new Scanner(System.in);
    System.out.println("Welcome to Paden9000 binary converter. Please enter an integer you wish to convert: ");
    int input = sc.nextInt();
    int printableInput = input;

    for (int i : powers) {
        if (input < i) {
            binaryStore.add(0);     
        } else {
            input = input - i;
            binaryStore.add(1);             
        }           
    }

    String newString= binaryStore.toString();
    String finalOutput = newString.replace("[", "")
            .replace(" ", "")
            .replace("]", "")
            .replace(",", "");

    System.out.println("Integer value: " + printableInput + "\nBinary value: " + finalOutput);
    sc.close();
}   

}

All of the casting causes errors, nothing here I tried worked, so I fiddled around and got this to work.

  foreach (DataGridViewRow row in dataGridView1.Rows)
        {
            if (row.Cells[0].Value != null && (bool)row.Cells[0].Value)
            {
                Console.WriteLine(row.Cells[0].Value);
            }

        }

for frequency distribution of a variable with excessive values you can collapse down the values in classes,

Here I excessive values for employrate variable, and there's no meaning of it's frequency distribution with direct values_count(normalize=True)

                country  employrate alcconsumption

[213 rows x 3 columns]

frequency distribution with values_count(normalize=True) with no classification,length of result here is 139 (seems meaningless as a frequency distribution):

print(gm["employrate"].value_counts(sort=False,normalize=True))

50.500000   0.005618
61.500000   0.016854

65.599998   0.005618
68.300003   0.005618
Name: employrate, Length: 139, dtype: float64

putting classification we put all values with a certain range ie.

0-10 as 1,
11-20 as 2  
21-30 as 3, and so forth.

gm["employrate"]=gm["employrate"].str.strip().dropna()  
gm["employrate"]=pd.to_numeric(gm["employrate"])
gm['employrate'] = np.where(
   (gm['employrate'] <=10) & (gm['employrate'] > 0) , 1, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=20) & (gm['employrate'] > 10) , 1, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=30) & (gm['employrate'] > 20) , 2, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=40) & (gm['employrate'] > 30) , 3, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=50) & (gm['employrate'] > 40) , 4, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=60) & (gm['employrate'] > 50) , 5, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=70) & (gm['employrate'] > 60) , 6, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=80) & (gm['employrate'] > 70) , 7, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=90) & (gm['employrate'] > 80) , 8, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=100) & (gm['employrate'] > 90) , 9, gm['employrate']
   )
print(gm["employrate"].value_counts(sort=False,normalize=True))

after classification we have a clear frequency distribution. here we can easily see, that 37.64% of countries have employ rate between 51-60% and 11.79% of countries have employ rate between 71-80%

5.000000   0.376404

4.000000   0.179775
6.000000   0.264045
8.000000   0.033708
3.000000   0.028090

After a few years and many attempts (I tried all the answers given here, but all of them had minor drawbacks at the end), now I realize that there is a better way than wanting to start, stop, restart a daemon directly from Python: use the OS tools instead.

For example, for Linux, instead of doing python myapp start and python myapp stop, I do this to start the app:

screen -S myapp python myapp.py    
CTRL+A, D to detach

or screen -dmS myapp python myapp.py to start and detach it in one command.

Then:

screen -r myapp

to attach to this terminal again. Once in the terminal, it's possible to use CTRL+C to stop it.

If you need Jenkins to access more then 1 project you will need to:
1. add public key to one github user account
2. add this user as Owner (to access all projects) or as a Collaborator in every project.

Many public keys for one system user will not work because GitHub will find first matched deploy key and will send back error like "ERROR: Permission to user/repo2 denied to user/repo1"

A view represents a virtual table. You can join multiple tables in a view and use the view to present the data as if the data were coming from a single table.

A stored procedure uses parameters to do a function... whether it is updating and inserting data, or returning single values or data sets.

Creating Views and Stored Procedures - has some information from Microsoft as to when and why to use each.

Say I have two tables:

• tbl_user, with columns: user_id, user_name, user_pw
• tbl_profile, with columns: profile_id, user_id, profile_description

So, if I find myself querying from those tables A LOT... instead of doing the join in EVERY piece of SQL, I would define a view like:

CREATE VIEW vw_user_profile
AS
  SELECT A.user_id, B.profile_description
  FROM tbl_user A LEFT JOIN tbl_profile B ON A.user_id = b.user_id
GO

Thus, if I want to query profile_description by user_id in the future, all I have to do is:

SELECT profile_description FROM vw_user_profile WHERE user_id = @ID

That code could be used in a stored procedure like:

CREATE PROCEDURE dbo.getDesc
    @ID int
AS
BEGIN
    SELECT profile_description FROM vw_user_profile WHERE user_id = @ID
END
GO

So, later on, I can call:

dbo.getDesc 25

and I will get the description for user_id 25, where the 25 is your parameter.

There is obviously a lot more detail, this is just the basic idea.

<label for="myInputID">myLabel</label><input type="checkbox" id="myInputID" name="myInputID />

In FontAwesome 4.0, the classes change to 'fa-2x', 'fa-3x'.

This works for MVC 5:

<a href="@Url.Action("ActionName", "ControllerName", new { paramName1 = item.paramValue1, paramName2 = item.paramValue2 })" >
    Link text
</a>

If you are using the SQL Management Studio, you can right click your DB name and select Tasks > Import/Export data and follow the wizard.
one of the steps is called "Specify Table Copy or Query" where there is an option to write a query to specify the data to transfer, so you can simply specify the following query:

select * from [Table] where Fk_CompanyId = 1

We can pass string value to main method as argument without using commandline argument concept in java through Netbean

 package MainClass;
 import java.util.Scanner;
 public class CmdLineArgDemo {

static{
 Scanner readData = new Scanner(System.in);   
 System.out.println("Enter any string :");
 String str = readData.nextLine();
 String [] str1 = str.split(" ");
 // System.out.println(str1.length);
 CmdLineArgDemo.main(str1);
}  

   public static void main(String [] args){
      for(int i = 0 ; i<args.length;i++) {
        System.out.print(args[i]+" ");
      }
    }
  }

Output

Enter any string : 
Coders invent Digital World 
Coders invent Digital World

isset() will return true if the variable has been initialised. If you have a form field with its name value set to userName, when that form is submitted the value will always be "set", although there may not be any data in it.

Instead, trim() the string and test its length

if("" == trim($_POST['userName'])){
    $username = 'Anonymous';
}      

You must instruct your logger not to send its messages on up to its parent logger:

...
import java.util.logging.*;
...
Logger logger = Logger.getLogger(this.getClass().getName());
logger.setUseParentHandlers(false);
...

However, this should be done before adding any more handlers to logger.

HTML

<ul class="list">
  <li>This is the text</li>
  <li>This is another text</li>
  <li>This is another another text</li>
</ul>

Use align-items instead of align-self and I also added flex-direction to column.

CSS

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

html,
body {
  height: 100%;
}

.list {
  display: flex;
  justify-content: center;
  flex-direction: column;  /* <--- I added this */
  align-items: center;   /* <--- Change here */
  height: 100px;
  width: 100%;
  background: silver;
}

.list li {  
  background: gold;
  height: 20%; 
}

I wrote a class for that too. http://blog.another-d-mention.ro/programming/read-load-files-from-zip-in-javascript/ You can load basic assets such as javascript/css/images directly from the zip using class methods. Hope it helps

SELECT
   CASE 
   WHEN xyz.something = 1 THEN 'SOMETEXT'
   WHEN xyz.somethingelse = 1 THEN 'SOMEOTHERTEXT'
   WHEN xyz.somethingelseagain = 2 THEN 'SOMEOTHERTEXTGOESHERE'
   ELSE 'SOMETHING UNKNOWN'
   END AS ColumnName;

This is the simplest way to do it if you need multiple lines. Wrap you span'd text in another span and specify its height with line-height. The trick to multiple lines is resetting the inner span's line-height.

<span class="textvalignmiddle"><span>YOUR TEXT HERE</span></span>

.textvalignmiddle {
    line-height: /*set height*/;
}

.textvalignmiddle > span {
    display: inline-block;
    vertical-align: middle;
    line-height: 1em; /*set line height back to normal*/
}

DEMO

Of course the outer span could be a div or whathaveyou

Generates query to update each table and column of each table.

I have used this to some of my projects before and was able to solved most of my COLLATION problems. (especially on JOINS XD) Hope some of you find it useful.

To use, just export results to delimited text (probably new line '\n')

-- EACH TABLE
SELECT CONCAT('ALTER TABLE ', TABLE_NAME,' CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;') AS 'USE DATABASE_NAME;' FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'DATABASE_NAME' AND TABLE_TYPE LIKE 'BASE TABLE'

-- EACH COLUMN
SELECT CONCAT('ALTER TABLE ', TABLE_NAME,' MODIFY COLUMN ', COLUMN_NAME,' ', DATA_TYPE, IF(CHARACTER_MAXIMUM_LENGTH IS NULL OR DATA_TYPE LIKE 'longtext', '', CONCAT('(',CHARACTER_MAXIMUM_LENGTH,')')),' COLLATE utf8mb4_unicode_ci;') AS 'USE DATABASE_NAME;' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'DATABASE_NAME' AND (SELECT INFORMATION_SCHEMA.TABLES.TABLE_TYPE FROM INFORMATION_SCHEMA.TABLES WHERE INFORMATION_SCHEMA.TABLES.TABLE_SCHEMA = INFORMATION_SCHEMA.COLUMNS.TABLE_SCHEMA AND INFORMATION_SCHEMA.TABLES.TABLE_NAME = INFORMATION_SCHEMA.COLUMNS.TABLE_NAME LIMIT 1) LIKE 'BASE TABLE' AND DATA_TYPE IN ('char','varchar') /* include other types if necessary */

Internally devtools injects an IIFE named getCompletions into the page, called when a key is pressed inside the Devtools console.

Looking at the source of that function, it uses a few global functions which can be overwritten.

By using the Error constructor it's possible to get the call stack, which will include getCompletions when called by Devtools.

Example:

const disableDevtools = callback => {_x000D_
  const original = Object.getPrototypeOf;_x000D_
_x000D_
  Object.getPrototypeOf = (...args) => {_x000D_
    if (Error().stack.includes("getCompletions")) callback();_x000D_
    return original(...args);_x000D_
  };_x000D_
};_x000D_
_x000D_
disableDevtools(() => {_x000D_
  console.error("devtools has been disabled");_x000D_
_x000D_
  while (1);_x000D_
});

If you want to search on both FROM and TO airports, you'll want to join on the Airports table twice - then you can use both from and to tables in your results set:

SELECT
   Flights.*,fromAirports.*,toAirports.*
FROM
   Flights
INNER JOIN 
   Airports fromAirports on Flights.fairport = fromAirports.code
INNER JOIN 
   Airports toAirports on Flights.tairport = toAirports.code
WHERE
 ...

Actually this would go faster in most of cases:

SELECT *
FROM table ta1
JOIN table ta2 on ta1.id != ta2.id
WHERE ta1.c2 = ta2.c2 and ta1.c3 = ta2.c3 and ta1.c4 = ta2.c4

You join on different rows which have the same values. I think it should work. Correct me if I'm wrong.

I thought I'd add another perspective here. The answer depends on whether the question is assuming weak scaling or strong scaling.

From Wikipedia:

Weak scaling: how the solution time varies with the number of processors for a fixed problem size per processor.

Strong scaling: how the solution time varies with the number of processors for a fixed total problem size.

If the question is assuming weak scaling then @Gonzalo's answer suffices. However if the question is assuming strong scaling, there's something more to add. In strong scaling you're assuming a fixed workload size so if you increase the number of threads, the size of the data that each thread needs to work on decreases. On modern CPUs memory accesses are expensive and would be preferable to maintain locality by keeping the data in caches. Therefore, the likely optimal number of threads can be found when the dataset of each thread fits in each core's cache (I'm not going into the details of discussing whether it's L1/L2/L3 cache(s) of the system).

This holds true even when the number of threads exceeds the number of cores. For example assume there's 8 arbitrary unit (or AU) of work in the program which will be executed on a 4 core machine.

Case 1: run with four threads where each thread needs to complete 2AU. Each thread takes 10s to complete (with a lot of cache misses). With four cores the total amount of time will be 10s (10s * 4 threads / 4 cores).

Case 2: run with eight threads where each thread needs to complete 1AU. Each thread takes only 2s (instead of 5s because of the reduced amount of cache misses). With four cores the total amount of time will be 4s (2s * 8 threads / 4 cores).

I've simplified the problem and ignored overheads mentioned in other answers (e.g., context switches) but hope you get the point that it might be beneficial to have more number of threads than the available number of cores, depending on the data size you're dealing with.

Seen a lot of recommendations to use a ConcurrentDictionary, but no solid examples of it, so I'm going to throw my hat into this solution race. I'm not a thread-safe developer, so if this code isn't solid, please speak up for the sake of those who follow after.

public static class XmlSerializerHelper
{
    private static readonly ConcurrentDictionary<Type, XmlSerializer> TypeSerializers = new ConcurrentDictionary<Type, XmlSerializer>();

    public static XmlSerializer GetSerializer(Type type)
    {
        return TypeSerializers.GetOrAdd(type,
        t =>
        {
            var importer = new XmlReflectionImporter();
            var mapping = importer.ImportTypeMapping(t, null, null);
            return new XmlSerializer(mapping);
        });
    }
}

I've seen other posts involving ConcurrentDictionary and Lazy loading the value. I'm not sure if that's relevant here or not, but here's the code for that:

private static readonly ConcurrentDictionary<Type, Lazy<XmlSerializer>> TypeSerializers = new ConcurrentDictionary<Type, Lazy<XmlSerializer>>();

public static XmlSerializer GetSerializer(Type type)
{
    return TypeSerializers.GetOrAdd(type,
    t =>
    {
        var importer = new XmlReflectionImporter();
        var mapping = importer.ImportTypeMapping(t, null, null);
        var lazyResult = new Lazy<XmlSerializer>(() => new XmlSerializer(mapping), LazyThreadSafetyMode.ExecutionAndPublication);
        return lazyResult;
    }).Value;
}

I don't recommend StartNew unless you need that level of complexity.

If your async method is dependent on other async methods, the easiest approach is to use the async keyword:

private static async Task<DateTime> CountToAsync(int num = 10)
{
  for (int i = 0; i < num; i++)
  {
    await Task.Delay(TimeSpan.FromSeconds(1));
  }

  return DateTime.Now;
}

If your async method is doing CPU work, you should use Task.Run:

private static async Task<DateTime> CountToAsync(int num = 10)
{
  await Task.Run(() => ...);
  return DateTime.Now;
}

You may find my async/await intro helpful.

You can do shortcut via inline function if you want to simply change the state variable without declaring a new function at top:

<input type="text" onChange={e => this.setState({ text: e.target.value })}/>

You can submit any form automatically on page load simply by adding a snippet of javascript code to your body tag referencing the form name like this....

<body onload="document.form1.submit()">

Nirsoft's NirCMD can create shortcuts from a command line, too. (Along with a pile of other functions.) Free and available here:

http://www.nirsoft.net/utils/nircmd.html

Full instructions here: http://www.nirsoft.net/utils/nircmd2.html#using (Scroll down to the "shortcut" section.)

Yes, using nircmd does mean you are using another 3rd-party .exe, but it can do some functions not in (most of) the above solutions (e.g., pick a icon # in a dll with multiple icons, assign a hot-key, and set the shortcut target to be minimized or maximized).

Though it appears that the shortcutjs.bat solution above can do most of that, too, but you'll need to dig more to find how to properly assign those settings. Nircmd is probably simpler.

When you are trying to sign in to your Google Account from your new device or application you have to unlock the CAPTCHA. To unlock the CAPTCHA go to https://www.google.com/accounts/DisplayUnlockCaptcha and then

And also make sure to allow less secure apps on

$(document).ready(function(){
    $('input.checkD[type="checkbox"]').click(function(){
        if($(this).prop("checked") == true){
            $(this).val('true');
        }
        else if($(this).prop("checked") == false){
            $(this).val('false');
        }
    });
});

You are trying to alter the behaviour of onclick inside the same function call. Try it like this:

Anchor tag

<a id="loginLink" onclick="toggleTable();" href="#">Login</a>

JavaScript

function toggleTable() {
    var lTable = document.getElementById("loginTable");
    lTable.style.display = (lTable.style.display == "table") ? "none" : "table";
}

If you are using the windows CMD you can use this command to create a database using sqlite3

C:\sqlite3.exe DBNAME.db ".read DBSCRIPT.sql"

If you haven't a database with that name sqlite3 will create one, and if you already have one, it will run it anyways but with the "TABLENAME already exists" error, I think you can also use this command to change an already existing database (but im not sure)

doReturn( value1, value2, value3 ).when( method-call )

This one looks better than the others I think.

USE  [enter your db name here]
GO

SELECT      SCHEMA_NAME(A.schema_id) + '.' +
        --A.Name, SUM(B.rows) AS 'RowCount'  Use AVG instead of SUM
          A.Name, AVG(B.rows) AS 'RowCount'
FROM        sys.objects A
INNER JOIN sys.partitions B ON A.object_id = B.object_id
WHERE       A.type = 'U'
GROUP BY    A.schema_id, A.Name
GO

I just want to add that if you don't inheritently know the name of a domain controller, you can get the closest one, pass it's hostname to the -Server argument.

$dc = Get-ADDomainController -DomainName example.com -Discover -NextClosestSite

    -Filter { EmailAddress -Like "*Smith_Karla*" } `
    -Properties EmailAddress

In the year 2020 / 2021 it is even easier with Array.from to 'convert' from a array-like nodes to an actual array, and then using .map to loop through the resulting array. The code is as simple as the follows:

Array.from(tableFields.children).map((child)=>console.log(child))

In this case a loop will also do the job (and is usually sufficiently fast).

a <- array(0, dim=dim(X))
for (i in 1:ncol(X)) {a[,i] <- X[,i]}

I thought my laptop was the origin…

That’s kind of nonsensical: origin refers to the default remote repository – the one you usually fetch/pull other people’s changes from.

How can I:

1. git remote -v will show you what origin is; origin/master is your “bookmark” for the last known state of the master branch of the origin repository, and your own master is a tracking branch for origin/master. This is all as it should be.

2. You don’t. At least it makes no sense for a repository to be the default remote repository for itself.

3. It isn’t. It’s merely telling you that you have made so-and-so many commits locally which aren’t in the remote repository (according to the last known state of that repository).

try:

[checked]="item.checked"

I'm using this localization method and added a route parameter that sets the culture and language whenever a user visits example.com/xx-xx/

Example:

routes.MapRoute("DefaultLocalized",
            "{language}-{culture}/{controller}/{action}/{id}",
            new
            {
                controller = "Home",
                action = "Index",
                id = "",
                language = "nl",
                culture = "NL"
            });

I have a filter that does the actual culture/language setting:

using System.Globalization;
using System.Threading;
using System.Web.Mvc;

public class InternationalizationAttribute : ActionFilterAttribute {

    public override void OnActionExecuting(ActionExecutingContext filterContext) {

        string language = (string)filterContext.RouteData.Values["language"] ?? "nl";
        string culture = (string)filterContext.RouteData.Values["culture"] ?? "NL";

        Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(string.Format("{0}-{1}", language, culture));
        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(string.Format("{0}-{1}", language, culture));

    }
}

To activate the Internationalization attribute, simply add it to your class:

[Internationalization]
public class HomeController : Controller {
...

Now whenever a visitor goes to http://example.com/de-DE/Home/Index the German site is displayed.

I hope this answers points you in the right direction.

I also made a small MVC 5 example project which you can find here

Just go to http://{yourhost}:{port}/en-us/home/index to see the current date in English (US), or change it to http://{yourhost}:{port}/de-de/home/index for German etcetera.

You can't. It's a browser feature there to prevent sites from showing hundreds of alerts to prevent you from leaving.

You can, however, look into modal popups like jQuery UI Dialog. These are javascript alert boxes that show a custom dialog. They don't use the default alert() function and therefore, bypass the issue you're running into completely.

I've found that an apps that has a lot of message boxes and confirms has a much better user experience if you use custom dialogs instead of the default alerts and confirms.

Well all I did to accomplish this is :

UIView *firstView = [webView.subviews firstObject];

if ([firstView isKindOfClass:[UIScrollView class]]) {

    UIScrollView *scroll = (UIScrollView*)firstView;
   [scroll setScrollEnabled:NO];  //to stop scrolling completely
   [scroll setBounces:NO]; //to stop bouncing 

}

Works fine for me... Also, the ticked answer for this question is one that Apple will reject if you use it in your iphone app.

Anyone looking to add insecure registry on amazon linux 2: You will have to change the setting under /etc/sysconfig/docker and then restart docker daemon: here's how my /etc/sysconfig/docker looks like

# running containers.  The default value of 1048576 mirrors the value
# used by the systemd service unit.
DAEMON_MAXFILES=1048576

# Additional startup options for the Docker daemon, for example:
# OPTIONS="--ip-forward=true --iptables=true"
# By default we limit the number of open files per container
OPTIONS="--default-ulimit nofile=1024:4096 --insecure-registry yourinsecureregistryhostname:port"

# How many seconds the sysvinit script waits for the pidfile to appear
# when starting the daemon.
DAEMON_PIDFILE_TIMEOUT=10

You can use the :before pseudo-selector to insert content in front of the list item. You can find an example on Quirksmode, at http://www.quirksmode.org/css/beforeafter.html. I use this to insert giant quotes around blockquotes...

A particularly feisty example is when you decide to show a managed Dialog from an Activity using showDialog(). If the user rotates the screen while the dialog is still open (we call this a "configuration change"), then the main Activity will go through all the ending lifecycle calls up untill onDestroy(), will be recreated, and go back up through the lifecycles. What you might not expect however, is that onCreateDialog() and onPrepareDialog() (the methods that are called when you do showDialog() and now again automatically to recreate the dialog - automatically since it is a managed dialog) are called between onStart() and onResume(). The pointe here is that the dialog does not cover the full screen and therefore leaves part of the main activity visible. It's a detail but it does matter!

Make sure your element with the .date-picker class does NOT already have a hasDatepicker class. If it does, even an attempt to re-initialize with $myDatepicker.datepicker(); will fail! Instead you need to do...

$myDatepicker.removeClass('hasDatepicker').datepicker();

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

Here's a solution similar to the currently accepted answer (https://stackoverflow.com/a/925630/95989), except that it uses the internal HTMLParser class directly (i.e. no subclassing), thereby making it significantly more terse:

def strip_html(text):
    parts = []                                                                      
    parser = HTMLParser()                                                           
    parser.handle_data = parts.append                                               
    parser.feed(text)

  <modal visible="showModal">

  </modal>
</div>

On button click toggleModal() function is called with the button message as parameter. This function toggles the visibility of popup. Any tags that you put inside will show up in the popup as content since ng-transclude is placed on modal-body in the directive template.

JS

var mymodal = angular.module('mymodal', []);

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.buttonClicked = "";
    $scope.toggleModal = function(btnClicked){
        $scope.buttonClicked = btnClicked;
        $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' +

        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;

UPDATE 2 restrict : 'E' : directive to be used as an HTML tag (element). Example in our case is

<modal>

Other values are 'A' for attribute

<div modal>

'C' for class (not preferable in our case because modal is already a class in bootstrap.css)

<div class="modal">

Note that the CDATA construct is only needed if placing text directly in the XML text file.

That is, you only need to use CDATA if hand typing or programmatically building the XML text directly.

Any text entered using a DOM processor API or SimpleXML will be automatically escaped to prevent running foul of XML content rules.

Notwithstanding that, there can be times where using CDATA can reduce the text size that would otherwise be produced with all entities encoded, such as for css in style tags or javascript in script tags, where many language constructs use characters in HTML|XML, like < and >.

An example done by me using the scroll (just HTML, CSS and JS, just with the jquery library). When scrolls down a button will slide left.

Also, I suggest you if the only one that you want is this effect, don't use jQuery UI because it's too heavy(if you just want to use it for that).

$(window).scroll(function(){
  if ($(this).scrollTop() > 100) {
          event.preventDefault();
          $(".scrollToTop").css({'transform': 'translate(0px, 0px)'});
      } else {
          $(".scrollToTop").css({'transform': 'translate(40px, 0px)'});
      }
  });

Check this example

FORMAT(X,D) Formats the number X to a format like '#,###,###.##', rounded to D decimal places, and returns the result as a string. If D is 0, the result has no decimal point or fractional part.

 SELECT FORMAT(12332.123456, 4);
        -> '12,332.1235'

This is very easy.

• Right click on your test project
• Add-->Existing item
• You can see a small arrow just beside the Add button
• Select the config file click on "Add As Link"

I think this way is easy:

>>> bytes_data = [112, 52, 52]
>>> "".join(map(chr, bytes_data))
'p44'

Yes, you can store any object (I assume you are using ASP.NET with default settings, which is in-process session state):

Session["test"] = myList;

You should cast it back to the original type for use:

var list = (List<int>)Session["test"];
// list.Add(something);

As Richard points out, you should take extra care if you are using other session state modes (e.g. SQL Server) that require objects to be serializable.

It by itself says that package.json is not available in your project. So, to create package.json, use the following steps:

1. open command prompt on your project directory
2. npm init (it will ask you to enter lots of entries like name, version, desc, etc., enter some random values and click enter).
3. type yes and click enter

Now try again.

Depending on you flavor of SQL, you can also imply the else statement in your aggregate counts.

For example, here's a simple table Grades:

| Letters |
|---------|
| A       |
| A       |
| B       |
| C       |

We can test out each Aggregate counter syntax like this (Interactive Demo in SQL Fiddle):

SELECT
    COUNT(CASE WHEN Letter = 'A' THEN 1 END)           AS [Count - End],
    COUNT(CASE WHEN Letter = 'A' THEN 1 ELSE NULL END) AS [Count - Else Null],
    COUNT(CASE WHEN Letter = 'A' THEN 1 ELSE 0 END)    AS [Count - Else Zero],
    SUM(CASE WHEN Letter = 'A' THEN 1 END)             AS [Sum - End],
    SUM(CASE WHEN Letter = 'A' THEN 1 ELSE NULL END)   AS [Sum - Else Null],
    SUM(CASE WHEN Letter = 'A' THEN 1 ELSE 0 END)      AS [Sum - Else Zero]
FROM Grades

And here are the results (unpivoted for readability):

|    Description    | Counts |
|-------------------|--------|
| Count - End       |    2   |
| Count - Else Null |    2   |
| Count - Else Zero |    4   | *Note: Will include count of zero values
| Sum - End         |    2   |
| Sum - Else Null   |    2   |
| Sum - Else Zero   |    2   |

Which lines up with the docs for Aggregate Functions in SQL

Docs for COUNT:

COUNT(*) - returns the number of items in a group. This includes NULL values and duplicates.
COUNT(ALL expression) - evaluates expression for each row in a group, and returns the number of nonnull values.
COUNT(DISTINCT expression) - evaluates expression for each row in a group, and returns the number of unique, nonnull values.

Docs for SUM:

ALL - Applies the aggregate function to all values. ALL is the default.
DISTINCT - Specifies that SUM return the sum of unique values.

Without code this is difficult to help you but here's some practical advice for you:

I suspect that your "image wall" has some sort of container with an id or class to give it styles.

eg:

<body>

<div id="maincontainer">
  <div id="header"></div>

  <div id="content">
    <div id="imagewall">
      <img src"img.jpg">
<!-- code continues -->

Styling a size on all images for your image wall, while not affecting other images, like you logo, etc. is easy if your code is set up similar to the above.

#imagewall img {
  width: 100px;
  height: 100px; }

But if your images are not perfectly square they will be skewed using this method.

You mention that you are doing this because IE doesn't support SVG.

The good news is that IE does support vector graphics. Okay, so it's in the form of a language called VML which only IE supports, rather than SVG, but it is there, and you can use it.

Google Maps, among others, will detect the browser capabilities to determine whether to serve SVG or VML.

Then there's the Raphael library, which is a Javascript browswer-based graphics library, which supports either SVG or VML, again depending on the browser.

Another one which may help: SVGWeb.

All of which means that you can support your IE users without having to resort to bitmap graphics.

See also the top answer to this question, for example: XSL Transform SVG to VML

Use double quotes:

$i = 1;
echo "
<p class=\"paragraph$i\">
</p>
";
++i;

To grab the device's IPv4 addresses, and filter to only grab ones that match your scheme (i.e. Ignore and APIPA addresses or the LocalHost address). You could say to grab the address matching 192.168.200.* for example.

$IPv4Addr = Get-NetIPAddress -AddressFamily ipV4 | where {$_.IPAddress -like X.X.X.X} | Select IPAddress

#include <stdio.h>
#include <stdlib.h>

char *name = "hello";

int main(void) {
  char *ext = ".txt";
  int len   = strlen(name) + strlen(ext) + 1;
  char *n2  = malloc(len);
  char *n2a = malloc(len);

  if (n2 == NULL || n2a == NULL)
    abort();

  strlcpy(n2, name, len);
  strlcat(n2, ext, len);
  printf("%s\n", n2);

  /* or for conforming C99 ...  */
  strncpy(n2a, name, len);
  strncat(n2a, ext, len - strlen(n2a));
  printf("%s\n", n2a);

  return 0; // this exits, otherwise free n2 && n2a
}

If ruby was installed in the following way:

./configure --prefix=/usr/local
make
sudo make install

You can uninstall it in the following way:

Check installed ruby version; lets assume 2.1.2

wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.bz2
bunzip ...
tar xfv ...
cd ruby-2.1.2
./configure --prefix=/usr/local
make
sudo checkinstall
  # will build deb or rpm package and try to install it

After installation, you can now remove the package and it will remove the directories/files/etc.

sudo rpm -e ruby # or dpkg -P ruby (for Debian-like systems)

There might be some artifacts left:

Removing ruby ...
  warning: while removing ruby, directory '/usr/local/lib/ruby/gems/2.1.0/gems' not empty so not removed.
  ...

Remove them manually.

This is because You're sorting entire result-set, You should sort, every part of union separately, or You can use ORDER BY (Something ie. subquery distance) THEN (something ie row id) clause

Great helps above, but if you having the similar environment like I did, this is how I get it to work.

• having a few jdk running, openjdk, oracle jdk and a few versions.
• install apache-maven via yum, package is apache-maven-3.2.1-1.el6.noarch

Edit this file /etc/profile.d/apache-maven.sh, such as the following, note that it will affect the whole system.

$ cat /etc/profile.d/apache-maven.sh
MAVEN_HOME=/usr/share/apache-maven
M2_HOME=$MAVEN_HOME
PATH=$MAVEN_HOME/bin:$PATH
# change below to the jdk you want mvn to reference.
JAVA_HOME=/usr/java/jdk1.7.0_40/
export MAVEN_HOME
export M2_HOME
export PATH
export JAVA_HOME

Faced same problem. Problem lies in required version not installed. Hack is simple Goto Platforms>platforms.json Edit platforms.json in front of android modify the version to the one which is installed on system.

My approach was, but I can't guarantee that this is the fastest solution.

df = pd.DataFrame(columns=["firstname", "lastname"])
df = df.append({
     "firstname": "John",
     "lastname":  "Johny"
      }, ignore_index=True)

Some programs can't process output stream very well, using pipe to Out-Null may not block it.
And Start-Process needs the -ArgumentList switch to pass arguments, not so convenient.
There is also another approach.

$exitCode = [Diagnostics.Process]::Start(<process>,<arguments>).WaitForExit(<timeout>)

This should get you started:

log4j.rootLogger=QuietAppender, LoudAppender, TRACE
# setup A1
log4j.appender.QuietAppender=org.apache.log4j.RollingFileAppender
log4j.appender.QuietAppender.Threshold=INFO
log4j.appender.QuietAppender.File=quiet.log
...


# setup A2
log4j.appender.LoudAppender=org.apache.log4j.RollingFileAppender
log4j.appender.LoudAppender.Threshold=DEBUG
log4j.appender.LoudAppender.File=loud.log
...

log4j.logger.com.yourpackage.yourclazz=TRACE

You can try this:

Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);

I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar from a Date and just get the month's diff.

On the face of it, it looks okay - if you call eraseCookie() on each cookie that is read from document.cookie, then all of your cookies will be gone.

Try this:

var cookies = document.cookie.split(";");
for (var i = 0; i < cookies.length; i++)
  eraseCookie(cookies[i].split("=")[0]);

All of this with the following caveat:

• JavaScript cannot remove cookies that have the HttpOnly flag set.

For Winforms

private void listBox1_DoubleClick(object sender, MouseEventArgs e)
    {
        int index = this.listBox1.IndexFromPoint(e.Location);
        if (index != System.Windows.Forms.ListBox.NoMatches)
        {
            MessageBox.Show(listBox1.SelectedItem.ToString());
        }
    }

and

public Form()
{
    InitializeComponent();
    listBox1.MouseDoubleClick += new MouseEventHandler(listBox1_DoubleClick);
}

that should also, prevent for the event firing if you select an item then click on a blank area.

My solution:

var pressedKeys = {};
window.onkeyup = function(e) { pressedKeys[e.keyCode] = false; }
window.onkeydown = function(e) { pressedKeys[e.keyCode] = true; }

I can now check if any key is pressed anywhere else in the script by checking

pressedKeys["code of the key"]

If it's true, the key is pressed.

If by "cursor speed", you mean the repeat rate when holding down a key - then have a look here: http://hints.macworld.com/article.php?story=20090823193018149

To summarize, open up a Terminal window and type the following command:

defaults write NSGlobalDomain KeyRepeat -int 0

More detail from the article:

Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:

defaults write NSGlobalDomain KeyRepeat -int 0

Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.

You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.

This is what I am using:

$("#search_code").live('change', function(){
  alert(this.value)
});

For latest jQuery users, this one should work:

$(document.body).on("change","#search_code",function(){
 alert(this.value);
});

The recommended solution to this is the extensible enum pattern.

This involves creating an interface and using that where you currently use the enum. Then make the enum implement the interface. You can add more constants by making that new enum also extend the interface.

Also you may need:

• SystemParameters.VirtualScreenWidth
• SystemParameters.VirtualScreenHeight

to get the combined size of all monitors and not one in particular.

There are some problems with your code. First I advise to use parametrized queries so you avoid SQL Injection attacks and also parameter types are discovered by framework:

var cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID = @id", con);
cmd.Parameters.AddWithValue("@id", id.Text);

Second, as you are interested only in one value getting returned from the query, it is better to use ExecuteScalar:

var name = cmd.ExecuteScalar();

if (name != null)
{
   position = name.ToString();
   Response.Write("User Registration successful");
}
else
{
    Console.WriteLine("No Employee found.");
}

The last thing is to wrap SqlConnection and SqlCommand into using so any resources used by those will be disposed of:

string position;

using (SqlConnection con = new SqlConnection("server=free-pc\\FATMAH; Integrated Security=True; database=Workflow; "))
{
  con.Open();

  using (var cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID = @id", con))
  {
    cmd.Parameters.AddWithValue("@id", id.Text);
  
    var name = cmd.ExecuteScalar();
  
    if (name != null)
    {
       position = name.ToString();
       Response.Write("User Registration successful");
    }
    else
    {
        Console.WriteLine("No Employee found.");
    }
  }
}

You can use the css property object-fit.

.cover {_x000D_
  object-fit: cover;_x000D_
  width: 50px;_x000D_
  height: 100px;_x000D_
}

<img src="http://i.stack.imgur.com/2OrtT.jpg" class="cover" width="242" height="363" />

See example here

There's a polyfill for IE: https://github.com/anselmh/object-fit

Get all group occurrence

let m=[], s = "something format_abc  format_def  format_ghi";_x000D_
_x000D_
s.replace(/(?:^|\s)format_(.*?)(?:\s|$)/g, (x,y)=> m.push(y));_x000D_
_x000D_
console.log(m);

The option -C works; just for clarification I'll post 2 examples:

1. creation of a tarball without the full path: full path /home/testuser/workspace/project/application.war and what we want is just project/application.war so:

   tar -cvf output_filename.tar  -C /home/testuser/workspace project
   

   Note: there is a space between workspace and project; tar will replace full path with just project .

2. extraction of tarball with changing the target path (default to ., i.e current directory)

   tar -xvf output_filename.tar -C /home/deploy/
   

   tar will extract tarball based on given path and preserving the creation path; in our example the file application.war will be extracted to /home/deploy/project/application.war.

   /home/deploy: given on extract
   project: given on creation of tarball

Note : if you want to place the created tarball in a target directory, you just add the target path before tarball name. e.g.:

tar -cvf /path/to/place/output_filename.tar  -C /home/testuser/workspace project

You will have to use the fluent API to do this.

Try adding the following to your DbContext:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{   
    modelBuilder.Entity<User>()
        .HasOptional(a => a.UserDetail)
        .WithOptionalDependent()
        .WillCascadeOnDelete(true);
}

I couldn't get the SDK to install properly (some of the files seemed unsigned, something like that). I found another solution here and that seems to work okay for me. It doesn't require installation of new files at all. Basically, what you do is:

Edit the .csproj file in a text editor, and add:

<Reference Include="System.Management.Automation" />

to the relevant section.

Hope this helps.

[4 rows x 8 columns]

In the project I'm working on, audit log also started from the very minimalistic design, like the one you described:

event ID
event date/time
event type
user ID
description

The idea was the same: to keep things simple.

However, it quickly became obvious that this minimalistic design was not sufficient. The typical audit was boiling down to questions like this:

Who the heck created/updated/deleted a record 
with ID=X in the table Foo and when?

So, in order to be able to answer such questions quickly (using SQL), we ended up having two additional columns in the audit table

object type (or table name)
object ID

That's when design of our audit log really stabilized (for a few years now).

Of course, the last "improvement" would work only for tables that had surrogate keys. But guess what? All our tables that are worth auditing do have such a key!

You may simply use (.autoplay = true;) as following (tested on Chrome Desktop):

<audio id="audioID" loop> <source src="path/audio.mp3"  type="audio/mp3"></audio>

<script>
var myaudio = document.getElementById("audioID").autoplay = true;
</script>

If you need to add stop/play buttons:

<button onclick="play()" type="button">playbutton</button>
<button onclick="stop()" type="button">stopbutton</button>

<audio id="audioID" autoplay loop> <source src="path/audio.mp3"  type="audio/mp3"> 
</audio>

<script>
var myaudio = document.getElementById("audioID");

function play() { 
return myaudio.play(); 
};

function stop() {
return myaudio.pause(); 
};
</script>

If you want stop/play to be one single button:

<button onclick="PlayStop()" type="button">button</button>


<audio id="audioID" autoplay loop> <source src="path/audio.mp3"  type="audio/mp3"> 
</audio>

<script>
var myaudio = document.getElementById("audioID");

function PlayStop() { 
return myaudio.paused ? myaudio.play() : myaudio.pause();
};
</script>

If you want to display stop/play on the same button:

<button onclick="PlayStop()" type="button">Play</button>


<audio id="audioID" autoplay loop> <source src="path/audio.mp3"  type="audio/mp3"> 
</audio>

<script>
var myaudio = document.getElementById("audioID");

function PlayStop() { 
if (elem.innerText=="Play") {
    elem.innerText = "Stop";
}
else {
    elem.innerText = "Play";
}
return myaudio.paused ? myaudio.play() : myaudio.pause();
};`
</script>

In some browsers audio may doesn't work correctly, so as a trick try adding iframe before your code:

<iframe src="dummy.mp3" allow="autoplay" id="audio" style="display:none"></iframe>

<button onclick="PlayStop()" type="button">Play</button>


<audio id="audioID" autoplay loop> <source src="path/audio.mp3"  type="audio/mp3"> 
</audio>

<script>
var myaudio = document.getElementById("audioID");

function button() { 
if (elem.innerText=="Play") {
    elem.innerText = "Stop";
}
else {
    elem.innerText = "Play";
}
return myaudio.paused ? myaudio.play() : myaudio.pause();
};
</script>

1. select *from table_name where boolean_column is False or Null;

   Is interpreted as "( boolean_column is False ) or (null)".

   It returns only rows where boolean_column is False as the second condition is always false.

2. select *from table_name where boolean_column is Null or False;

   Same reason. Interpreted as "(boolean_column is Null) or (False)"

3. select *from table_name where boolean_column is Null or boolean_column = False;

   This one is valid and returns 2 rows: false and null.

I just created the table to confirm. You might have typoed somewhere.

There is no difference, in browsers that you can find in the wild these days (that is, excluding things like Netscape 1 that you might find in a museum). There is no reason to suspect that any of them would be deprecated ever, especially since they are all valid in XML, in HTML 4.01, and in HTML5 CR.

There is no reason to use any of them, as opposite to using the Ascii quotation mark (") directly, except in the very special case where you have an attribute value enclosed in such marks and you would like to use the mark inside the value (e.g., title="Hello "world""), and even then, there are almost always better options (like title='Hello "word"' or title="Hello “word”".

If you want to use “smart” quotation marks instead, then it’s a different question, and none of the constructs has anything to do with them. Some people expect notations like " to produce “smart” quotes, but it is easy to see that they don’t; the notations unambiguously denote the Ascii quote ("), as used in computer languages.

session.query().with_entities(SomeModel.col1)

is the same as

session.query(SomeModel.col1)

for alias, we can use .label()

session.query(SomeModel.col1.label('some alias name'))

awk ' { print ( $(NF-1) ) }' file

Here is a ridiculously brute force answer:

I modified the gradlew script. Here is my new exec command at the end of the file in the

exec "$JAVACMD" "${JVM_OPTS[@]}" -classpath "$CLASSPATH" org.gradle.wrapper.GradleWrapperMain "$@" **| grep -v "libpng warning:"**

If you want to call functions on components from outside React, you can call them on the return value of renderComponent:

var Child = React.createClass({…});
var myChild = React.renderComponent(Child);
myChild.someMethod();

The only way to get a handle to a React Component instance outside of React is by storing the return value of React.renderComponent. Source.

The features available to use are dependent on your processor. Apple uses the same Intel stuff as everybody else. So yes, generic x86 should be fine (assuming you're not on a PPC :D).

As far as tools go, I think your best bet is a good text editor that 'understands' assembly.

You could do it easily with an extension function rather than a regex ...

public static bool IsAlphaNum(this string str)
{
    if (string.IsNullOrEmpty(str))
        return false;

    for (int i = 0; i < str.Length; i++)
    {
        if (!(char.IsLetter(str[i])) && (!(char.IsNumber(str[i]))))
            return false;
    }

    return true;
}

Per comment :) ...

public static bool IsAlphaNum(this string str)
{
    if (string.IsNullOrEmpty(str))
        return false;

    return (str.ToCharArray().All(c => Char.IsLetter(c) || Char.IsNumber(c)));
}

I think this code answer your question

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) 
holder.desc1.getLayoutParams();
params.height = RelativeLayout.LayoutParams.WRAP_CONTENT;
holder.desc1.setLayoutParams(params);

:1,.d deletes lines 1 to current.
:1,.-1d deletes lines 1 to above current.

(Personally I'd use dgg or kdgg like the other answers, but TMTOWTDI.)

I actually often use Java style: PascalCase for type names, camelCase for functions and variables, CAPITAL_WORDS for preprocessor macros. I prefer that over the Boost/STL conventions because you don't have to suffix types with _type. E.g.

Size size();

instead of

size_type size();   // I don't like suffixes

This has the additional benefit that the StackOverflow code formatter recognizes Size as a type name ;-)

If you're using at least .NET 3.5, i would suggest to use Linq-To-DataTable instead since it's much more readable and powerful:

DataTable tblFiltered = table.AsEnumerable()
          .Where(row => row.Field<String>("Nachname") == username
                   &&   row.Field<String>("Ort") == location)
          .OrderByDescending(row => row.Field<String>("Nachname"))
          .CopyToDataTable();

Above code is just an example, actually you have many more methods available.

Remember to add using System.Linq; and for the AsEnumerable extension method a reference to the System.Data.DataSetExtensions dll (How).

I wasn't happy with any of the awk solutions presented here because I wanted to extract the first few columns and then print the rest, so I turned to perl instead. The following code extracts the first two columns, and displays the rest as is:

echo -e "a  b  c  d\te\t\tf g" | \
  perl -ne 'my @f = split /\s+/, $_, 3; printf "first: %s second: %s rest: %s", @f;'

The advantage compared to the perl solution from Chris Koknat is that really only the first n elements are split off from the input string; the rest of the string isn't split at all and therefor stays completely intact. My example demonstrates this with a mix of spaces and tabs.

To change the amount of columns that should be extracted, replace the 3 in the example with n+1.

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

I found another solution elsewhere; that is, to use

upper(@yourString)

but everyone here is saying that, in SQL Server, it doesn't matter because it's ignoring case anyway? I'm pretty sure our database is case-sensitive.

If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:

curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Doing this you'll force to use es without replicas

For bootstrap 4 I have to add media query with max-width: none

@media (min-width: 576px) {
  .modal-dialog { max-width: none; }
}

.modal-dialog {
  width: 98%;
  height: 92%;
  padding: 0;
}

.modal-content {
  height: 99%;
}

1. The query is correct

2A. As far as last seven days have much less rows than whole table an index can help

2B. If you are interested only in Created_Date you can try using some group by and count, it should help with the result set size

Add the below to your manifest:

  <activity   android:name=".AppPreferenceActivity" android:label="@string/app_name">  
     <intent-filter> 
       <action android:name="com.scytec.datamobile.vd.gui.android.AppPreferenceActivity" />  
       <category android:name="android.intent.category.DEFAULT" />  
     </intent-filter>   
  </activity>

I tried in online compiler https://www.onlinegdb.com/online_c++_compiler

int main()
{
    cout<<"Hello World";
    int x = 10;
    int *p = &x;
    printf("\nAddress of x is %p\n", &x); // 0x7ffc7df0ea54
    printf("Address of p is %p\n", p);    // 0x7ffc7df0ea54

    return 0;
}

2018 edit: This answer is from 2011, before browsers had widely supported array filtering methods and arrow functions. Have a look at CAFxX's answer.

There is no "magic" way to check for something in an array without a loop. Even if you use some function, the function itself will use a loop. What you can do is break out of the loop as soon as you find what you're looking for to minimize computational time.

var found = false;
for(var i = 0; i < vendors.length; i++) {
    if (vendors[i].Name == 'Magenic') {
        found = true;
        break;
    }
}

If you make all the properties animated the same, you can set each separately which will allow you to not repeat the code.

 transition: all 2s;
 transition-property: color, text-shadow;

There is more about it here: CSS transition shorthand with multiple properties?

I would avoid using the property all (transition-property overwrites 'all'), since you could end up with unwanted behavior and unexpected performance hits.

You can also use unlist(), which is often useful for handling lists:

> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))

> mylist
$A
[1] 1 2 3

$B
[1] 4 5 6

$C
[1] 7 8 9

> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3 
 1  2  3  4  5  6  7  8  9 

> length(unlist(mylist))
[1] 9

unlist() is a simple way of executing other functions on lists as well, such as:

> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument

> sum(unlist(mylist))
[1] 45

You don't want to use terminal: false since that's what's blocking the processing of inside the button. Instead, in your link clear the attr.ngClick to prevent the default behavior.

http://plnkr.co/edit/EySy8wpeQ02UHGPBAIvg?p=preview

app.directive('ngConfirmClick', [
  function() {
    return {
      priority: 1,
      link: function(scope, element, attr) {
        var msg = attr.ngConfirmClick || "Are you sure?";
        var clickAction = attr.ngClick;
        attr.ngClick = "";
        element.bind('click', function(event) {
          if (window.confirm(msg)) {
            scope.$eval(clickAction)
          }
        });
      }
    };
  }
]);

These answers were helpful, but I wanted to share my answer with both the app.config part and the c# code part, so there is less guessing for the next person.

<log4net>
  <appender name="SomeName" type="log4net.Appender.RollingFileAppender">
    <file value="c:/Console.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value="yyyyMMdd" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="1MB" />
  </appender>
  <appender name="Summary" type="log4net.Appender.FileAppender">
    <file value="SummaryFile.log" />
    <appendToFile value="true" />
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="SomeName" />
  </root>
  <logger additivity="false" name="Summary">
    <level value="DEBUG"/>
    <appender-ref ref="Summary" />
  </logger>
</log4net>

Then in code:

ILog Log = LogManager.GetLogger("SomeName");
ILog SummaryLog = LogManager.GetLogger("Summary");
Log.DebugFormat("Processing");
SummaryLog.DebugFormat("Processing2"));

Here c:/Console.txt will contain "Processing" ... and \SummaryFile.log will contain "Processing2"

Add programatically noborder class to specific row to hide it

<style>
     .noborder
      {
        border:none;
      }
    </style>

<table>

    <tr>
       <th>heading1</th>
       <th>heading2</th>
    </tr>


    <tr>
       <td>content1</td>
       <td>content2</td>
    </tr>
    /*no border for this row */
    <tr class="noborder">
       <td>content1</td>
       <td>content2</td>
    </tr>

</table>

This type of thing should be done server-side, so as to limit the amount of resources used on the client for such trivial tasks. That being said, if you were to do it on the front-end, I would encourage you to consider using something like underscore.js to keep the code clean and concise:

var values = ["Red", "Green"],
    colors = document.getElementById("colors");

_.each(colors.options, function (option) {
    option.selected = ~_.indexOf(values, option.text);
});

If you're using jQuery, it could be even more terse:

var values = ["Red", "Green"];

$("#colors option").prop("selected", function () {
    return ~$.inArray(this.text, values);
});

If you were to do this without a tool like underscore.js or jQuery, you would have a bit more to write, and may find it to be a bit more complicated:

var color, i, j,
    values = ["Red", "Green"],
    options = document.getElementById("colors").options;

for ( i = 0; i < values.length; i++ ) {
    for ( j = 0, color = values[i]; j < options.length; j++ ) {
        options[j].selected = options[j].selected || color === options[j].text;
    }
}

try this, I think this will help and your blue border will be removed:

outline:none;

If you want to get and set the property both, you can use this in C#7:

GetString(
    inputString,
    (() => client.WorkPhone, x => client.WorkPhone = x))

void GetString(string inValue, (Func<string> get, Action<string> set) outValue)
{
    if (!string.IsNullOrEmpty(outValue))
    {
        outValue.set(inValue);
    }
}

(x > 0 for x in list) in that function call creates a generator expression eg.

>>> nums = [1, 2, -1, 9, -5]
>>> genexp = (x > 0 for x in nums)
>>> for x in genexp:
        print x


True
True
False
True
False

Which any uses, and shortcircuits on encountering the first object that evaluates True

In case you'd happen to be using rails and the angular-rails gem then the problem is easily corrected by adding this missing line to application.js (or what ever is applicable in your situation):

//= require angular-resource

I found that doing it in two relatively simple steps seemed to work quite well. The first css definition for ul sets the base indent that you want for the list as a whole. The second definition sets the indent value for each nested list item within it. In my case they are the same, but you can obviously pick whatever you want.

ul {
    margin-left: 1.5em;
}

ul > ul {
    margin-left: 1.5em;
}

System.getProperty("user.dir") fetches the directory or path of the workspace for the current project

Places is a list and not a dictionary. This line below should therefore not work:

print data['places']['latitude']

You need to select one of the items in places and then you can list the place's properties. So to get the first post code you'd do:

print data['places'][0]['post code']

var classList = $(element).attr('class').split(/\s+/);
$(classList).each(function(index){

     //do something

});

Group by is expensive than Distinct since Group by does a sort on the result while distinct avoids it. But if you want to make group by yield the same result as distinct give order by null ..

SELECT DISTINCT u.profession FROM users u

is equal to

SELECT u.profession FROM users u GROUP BY u.profession order by null

I've had a lot of issues with developers checking in their console.() statements. And, I really don't like debugging Internet Explorer, despite the fantastic improvements of Internet Explorer 10 and Visual Studio 2012, etc.

So, I've overridden the console object itself... I've added a __localhost flag that only allows console statements when on localhost. I also added console.() functions to Internet Explorer (that displays an alert() instead).

// Console extensions...
(function() {
    var __localhost = (document.location.host === "localhost"),
        __allow_examine = true;

    if (!console) {
        console = {};
    }

    console.__log = console.log;
    console.log = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__log === "function") {
                console.__log(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__info = console.info;
    console.info = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__info === "function") {
                console.__info(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__warn = console.warn;
    console.warn = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__warn === "function") {
                console.__warn(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__error = console.error;
    console.error = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__error === "function") {
                console.__error(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg);
            }
        }
    };

    console.__group = console.group;
    console.group = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__group === "function") {
                console.__group(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert("group:\r\n" + msg + "{");
            }
        }
    };

    console.__groupEnd = console.groupEnd;
    console.groupEnd = function() {
        if (__localhost) {
            if (typeof console !== "undefined" && typeof console.__groupEnd === "function") {
                console.__groupEnd(arguments);
            } else {
                var i, msg = "";
                for (i = 0; i < arguments.length; ++i) {
                    msg += arguments[i] + "\r\n";
                }
                alert(msg + "\r\n}");
            }
        }
    };

    /// To enable __examine_() statements for sections/groups of code, type the

    console.examine = function() {
        if (!__allow_examine) {
            return;
        }
        if (arguments.length > 0) {
            var obj = top["__examine_" + arguments[0]];
            if (obj && obj === true) {
                console.log(arguments.splice(0, 1));
            }
        }
    };
})();

Example use:

    console.log("hello");

Chrome/Firefox:

    prints hello in the console window.

Internet Explorer:

    displays an alert with 'hello'.

For those who look closely at the code, you'll discover the console.examine() function. I created this years ago so that I can leave debug code in certain areas around the product to help troubleshoot QA/customer issues. For instance, I would leave the following line in some released code:

    function doSomething(arg1) {
        // ...
        console.examine("someLabel", arg1);
        // ...
    }

And then from the released product, type the following into the console (or address bar prefixed with 'javascript:'):

    top.__examine_someLabel = true;

Then, I will see all of the logged console.examine() statements. It's been a fantastic help many times over.

THE BEST AND EASIEST WAY

If you think that you could win with a simple magic command you are failed! SVN is really tricky and always come back somehow with a new error message in Xcode. Sooner or later, promise... so you have to do it smart!

As you know the regular and best practice under Xcode is deleting a file on the project pane on the left. If you missed it and somehow deleted it in Finder you are in trouble. Big trouble! But you could solve it and spare time if you do it well.

First, you need to delete the SVN reference to the file or folder before you could delete it actually

1. If you could just put back the file/folder from the trash or undo the last step when you deleted it, then...

2. Go to Terminal - yes, the good old terminal - and go to that location. Best way just type cd then pull the folder/file to the Terminal. You will get something similar

cd /Users/UserName/Documents/Apps_Developing/...

You could check where are you with

ls

command which list your files.

3. Then you need to delete the svn reference with an SVN command:

   svn delete --keep-local fileName_toDelete

This will delete the file from the SVN repository, BUT you have to delete it manually in Finder.

<script>
function SetBack(dir) {
    document.getElementById('body').style.backgroundImage=dir;
}
SetBack('url(myniftybg.gif)');
</script>

Since you are using textarea, you may find \n or \r (or \r\n) for line breaks. So, the following is suggested:

$('#keywords').val().split(/\r|\n/)

ref: check whether string contains a line break

Put the recyclerview in any other layout (Relative layout is preferable). Then change recyclerview's height/width as match parent to that layout and set the parent layout's height/width as wrap content.

At least in case of EclipseLink 10g and 11g differ. Since 11g it is not recommended to use first_rows hint for pagination queries.

See "Is it possible to disable jpa hints per particular query". Such a query should not be used in 11g.

SELECT * FROM (
  SELECT /*+ FIRST_ROWS */ a.*, ROWNUM rnum  FROM (
    SELECT * FROM TABLES INCLUDING JOINS, ORDERING, etc.) a

WHERE rnum > 0;

But there can be other nuances.

As others have said, there is no universally correct block size; what is optimal for one situation or one piece of hardware may be terribly inefficient for another. Also, depending on the health of the disks it may be preferable to use a different block size than what is "optimal".

One thing that is pretty reliable on modern hardware is that the default block size of 512 bytes tends to be almost an order of magnitude slower than a more optimal alternative. When in doubt, I've found that 64K is a pretty solid modern default. Though 64K usually isn't THE optimal block size, in my experience it tends to be a lot more efficient than the default. 64K also has a pretty solid history of being reliably performant: You can find a message from the Eug-Lug mailing list, circa 2002, recommending a block size of 64K here: http://www.mail-archive.com/[email protected]/msg12073.html

For determining THE optimal output block size, I've written the following script that tests writing a 128M test file with dd at a range of different block sizes, from the default of 512 bytes to a maximum of 64M. Be warned, this script uses dd internally, so use with caution.

dd_obs_test.sh:

#!/bin/bash

# Since we're dealing with dd, abort if any errors occur
set -e

TEST_FILE=${1:-dd_obs_testfile}
TEST_FILE_EXISTS=0
if [ -e "$TEST_FILE" ]; then TEST_FILE_EXISTS=1; fi
TEST_FILE_SIZE=134217728

if [ $EUID -ne 0 ]; then
  echo "NOTE: Kernel cache will not be cleared between tests without sudo. This will likely cause inaccurate results." 1>&2
fi

I've only tested this script on a Debian (Ubuntu) system and on OSX Yosemite, so it will probably take some tweaking to make work on other Unix flavors.

By default the command will create a test file named dd_obs_testfile in the current directory. Alternatively, you can provide a path to a custom test file by providing a path after the script name:

$ ./dd_obs_test.sh /path/to/disk/test_file

The output of the script is a list of the tested block sizes and their respective transfer rates like so:

$ ./dd_obs_test.sh
block size : transfer rate
       512 : 11.3 MB/s
      1024 : 22.1 MB/s
      2048 : 42.3 MB/s
      4096 : 75.2 MB/s
      8192 : 90.7 MB/s
     16384 : 101 MB/s
     32768 : 104 MB/s
     65536 : 108 MB/s
    131072 : 113 MB/s
    262144 : 112 MB/s
    524288 : 133 MB/s
   1048576 : 125 MB/s
   2097152 : 113 MB/s
   4194304 : 106 MB/s
   8388608 : 107 MB/s
  16777216 : 110 MB/s
  33554432 : 119 MB/s
  67108864 : 134 MB/s

(Note: The unit of the transfer rates will vary by OS)

To test optimal read block size, you could use more or less the same process, but instead of reading from /dev/zero and writing to the disk, you'd read from the disk and write to /dev/null. A script to do this might look like so:

dd_ibs_test.sh:

#!/bin/bash

# Since we're dealing with dd, abort if any errors occur
set -e

TEST_FILE=${1:-dd_ibs_testfile}
if [ -e "$TEST_FILE" ]; then TEST_FILE_EXISTS=$?; fi
TEST_FILE_SIZE=134217728

# Exit if file exists
if [ -e $TEST_FILE ]; then
  echo "Test file $TEST_FILE exists, aborting."
  exit 1
fi
TEST_FILE_EXISTS=1

if [ $EUID -ne 0 ]; then
  echo "NOTE: Kernel cache will not be cleared between tests without sudo. This will likely cause inaccurate results." 1>&2
fi

# Create test file
echo 'Generating test file...'
BLOCK_SIZE=65536
COUNT=$(($TEST_FILE_SIZE / $BLOCK_SIZE))
dd if=/dev/urandom of=$TEST_FILE bs=$BLOCK_SIZE count=$COUNT conv=fsync > /dev/null 2>&1

do
  # Clear kernel cache to ensure more accurate test

  # Extract transfer rate

An important difference in this case is that the test file is a file that is written by the script. Do not point this command at an existing file or the existing file will be overwritten with zeroes!

For my particular hardware I found that 128K was the most optimal input block size on a HDD and 32K was most optimal on a SSD.

Though this answer covers most of my findings, I've run into this situation enough times that I wrote a blog post about it: http://blog.tdg5.com/tuning-dd-block-size/ You can find more specifics on the tests I performed there.

This is the basic delegate code you need:

#define kAccelerationThreshold      2.2

#pragma mark -
#pragma mark UIAccelerometerDelegate Methods
    - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration 
    {   
        if (fabsf(acceleration.x) > kAccelerationThreshold || fabsf(acceleration.y) > kAccelerationThreshold || fabsf(acceleration.z) > kAccelerationThreshold) 
            [self myShakeMethodGoesHere];   
    }

Also set the in the appropriate code in the Interface. i.e:

@interface MyViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource, UIAccelerometerDelegate>

You can use MySQL Table Data Import Wizard

I would imagine that this would be covered by CSS Tables, a specification which, while mentioned on the CSS homepage, appears to currently be at a state of "not yet published in any form"

In practical terms, you can't achieve this at present.

Using guava:

List<String> stringList=Lists.transform(list,new Function<Object,String>(){
    @Override
    public String apply(Object arg0) {
        if(arg0!=null)
            return arg0.toString();
        else
            return "null";
    }
});

Kevin Hakanson said: "However, if you know your XML string is valid, and you don't want to incur the memory overhead of parsing a string into a DOM, then running a transform over the DOM to get a string back - you could just do some old fashioned character by character parsing. Insert a newline and spaces after every characters, keep and indent counter (to determine the number of spaces) that you increment for every <...> and decrement for every you see."

Agreed. Such an approach is much faster and has far fewer dependencies.

Google aparently has a library for this sort of thing: http://code.google.com/p/jlibs/wiki/AnsiColoring

There's also a Javaworld article on this which solves your problem: http://www.javaworld.com/javaworld/javaqa/2002-12/02-qa-1220-console.html

There is a lot of confusion around lambdas and closures, even in the answers to this StackOverflow question here. Instead of asking random programmers who learned about closures from practice with certain programming languages or other clueless programmers, take a journey to the source (where it all began). And since lambdas and closures come from Lambda Calculus invented by Alonzo Church back in the '30s before first electronic computers even existed, this is the source I'm talking about.

Lambda Calculus is the simplest programming language in the world. The only things you can do in it:?

• APPLICATION: Applying one expression to another, denoted f x.
  (Think of it as a function call, where f is the function and x is its only parameter)
• ABSTRACTION: Binds a symbol occurring in an expression to mark that this symbol is just a "slot", a blank box waiting to be filled with value, a "variable" as it were. It is done by prepending a Greek letter ? (lambda), then the symbolic name (e.g. x), then a dot . before the expression. This then converts the expression into a function expecting one parameter.
  For example: ?x.x+2 takes the expression x+2 and tells that the symbol x in this expression is a bound variable – it can be substituted with a value you supply as a parameter.
  Note that the function defined this way is anonymous – it doesn't have a name, so you can't refer to it yet, but you can immediately call it (remember application?) by supplying it the parameter it is waiting for, like this: (?x.x+2) 7. Then the expression (in this case a literal value) 7 is substituted as x in the subexpression x+2 of the applied lambda, so you get 7+2, which then reduces to 9 by common arithmetics rules.

So we've solved one of the mysteries:
lambda is the anonymous function from the example above, ?x.x+2.

function(x) { return x+2; }

and you can immediately apply it to some parameter like this:

(function(x) { return x+2; })(7)

or you can store this anonymous function (lambda) into some variable:

var f = function(x) { return x+2; }

which effectively gives it a name f, allowing you to refer to it and call it multiple times later, e.g.:

alert(  f(7) + f(10)  );   // should print 21 in the message box

But you didn't have to name it. You could call it immediately:

alert(  function(x) { return x+2; } (7)  );  // should print 9 in the message box

In LISP, lambdas are made like this:

(lambda (x) (+ x 2))

and you can call such a lambda by applying it immediately to a parameter:

(  (lambda (x) (+ x 2))  7  )

As I said, what the lambda abstraction does is binding a symbol in its subexpression, so that it becomes a substitutible parameter. Such a symbol is called bound. But what if there are other symbols in the expression? For example: ?x.x/y+2. In this expression, the symbol x is bound by the lambda abstraction ?x. preceding it. But the other symbol, y, is not bound – it is free. We don't know what it is and where it comes from, so we don't know what it means and what value it represents, and therefore we cannot evaluate that expression until we figure out what y means.

In fact, the same goes with the other two symbols, 2 and +. It's just that we are so familiar with these two symbols that we usually forget that the computer doesn't know them and we need to tell it what they mean by defining them somewhere, e.g. in a library or the language itself.

You can think of the free symbols as defined somewhere else, outside the expression, in its "surrounding context", which is called its environment. The environment might be a bigger expression that this expression is a part of (as Qui-Gon Jinn said: "There's always a bigger fish" ;) ), or in some library, or in the language itself (as a primitive).

This lets us divide lambda expressions into two categories:

• CLOSED expressions: every symbol that occurs in these expressions is bound by some lambda abstraction. In other words, they are self-contained; they don't require any surrounding context to be evaluated. They are also called combinators.
• OPEN expressions: some symbols in these expressions are not bound – that is, some of the symbols occurring in them are free and they require some external information, and thus they cannot be evaluated until you supply the definitions of these symbols.

You can CLOSE an open lambda expression by supplying the environment, which defines all these free symbols by binding them to some values (which may be numbers, strings, anonymous functions aka lambdas, whatever…).

And here comes the closure part:
The closure of a lambda expression is this particular set of symbols defined in the outer context (environment) that give values to the free symbols in this expression, making them non-free anymore. It turns an open lambda expression, which still contains some "undefined" free symbols, into a closed one, which doesn't have any free symbols anymore.

For example, if you have the following lambda expression: ?x.x/y+2, the symbol x is bound, while the symbol y is free, therefore the expression is open and cannot be evaluated unless you say what y means (and the same with + and 2, which are also free). But suppose that you also have an environment like this:

{  y: 3,
+: [built-in addition],
2: [built-in number],
q: 42,
w: 5  }

This environment supplies definitions for all the "undefined" (free) symbols from our lambda expression (y, +, 2), and several extra symbols (q, w). The symbols that we need to be defined are this subset of the environment:

{  y: 3,
+: [built-in addition],
2: [built-in number]  }

and this is precisely the closure of our lambda expression :>

In other words, it closes an open lambda expression. This is where the name closure came from in the first place, and this is why so many people's answers in this thread are not quite correct :P

Well, the corporate marketoids of Sun/Oracle, Microsoft, Google etc. are to blame, because that's what they called these constructs in their languages (Java, C#, Go etc.). They often call "closures" what are supposed to be just lambdas. Or they call "closures" a particular technique they used to implement lexical scoping, that is, the fact that a function can access the variables that were defined in its outer scope at the time of its definition. They often say that the function "encloses" these variables, that is, captures them into some data structure to save them from being destroyed after the outer function finishes executing. But this is just made-up post factum "folklore etymology" and marketing, which only makes things more confusing, because every language vendor uses its own terminology.

And it's even worse because of the fact that there's always a bit of truth in what they say, which does not allow you to easily dismiss it as false :P Let me explain:

If you want to implement a language that uses lambdas as first-class citizens, you need to allow them to use symbols defined in their surrounding context (that is, to use free variables in your lambdas). And these symbols must be there even when the surrounding function returns. The problem is that these symbols are bound to some local storage of the function (usually on the call stack), which won't be there anymore when the function returns. Therefore, in order for a lambda to work the way you expect, you need to somehow "capture" all these free variables from its outer context and save them for later, even when the outer context will be gone. That is, you need to find the closure of your lambda (all these external variables it uses) and store it somewhere else (either by making a copy, or by preparing space for them upfront, somewhere else than on the stack). The actual method you use to achieve this goal is an "implementation detail" of your language. What's important here is the closure, which is the set of free variables from the environment of your lambda that need to be saved somewhere.

It didn't took too long for people to start calling the actual data structure they use in their language's implementations to implement closure as the "closure" itself. The structure usually looks something like this:

Closure {
   [pointer to the lambda function's machine code],
   [pointer to the lambda function's environment]
}

and these data structures are being passed around as parameters to other functions, returned from functions, and stored in variables, to represent lambdas, and allowing them to access their enclosing environment as well as the machine code to run in that context. But it's just a way (one of many) to implement closure, not the closure itself.

As I explained above, the closure of a lambda expression is the subset of definitions in its environment that give values to the free variables contained in that lambda expression, effectively closing the expression (turning an open lambda expression, which cannot be evaluated yet, into a closed lambda expression, which can then be evaluated, since all the symbols contained in it are now defined).

Anything else is just a "cargo cult" and "voo-doo magic" of programmers and language vendors unaware of the real roots of these notions.

I hope that answers your questions. But if you had any follow-up questions, feel free to ask them in the comments, and I'll try to explain it better.

The following answer is not exactly optimal by any measure, but I needed something that maintains its position within the container whilst it stretches the inner div fully.

https://jsfiddle.net/fah5axm5/

$(function() {
    $(window).on('load resize', ppaFullWidth);

    function ppaFullWidth() {
        var $elements = $('[data-ppa-full-width="true"]');
        $.each( $elements, function( key, item ) {
            var $el = $(this);
            var $container = $el.closest('.container');
            var margin = parseInt($container.css('margin-left'), 10);
            var padding = parseInt($container.css('padding-left'), 10)
            var offset = margin + padding;

            $el.css({
                position: "relative",
                left: -offset,
                "box-sizing": "border-box",
                width: $(window).width(),
                "padding-left": offset + "px",
                "padding-right": offset + "px"
            });
        });
    }
});

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

Sure you can create an html template and I would recommend also a text template. In the template you can just put [BODY] in the place where the body would be placed and then you can just read in the template and replace the body with the new content. You can send the email using .Nets Mail Class. You just have to loop through the sending of the email to all recipients after you create the email initially. Worked like a charm for me.

using System.Net.Mail;

// Email content
string HTMLTemplatePath = @"path";
string TextTemplatePath = @"path";
string HTMLBody = "";
string TextBody = "";

HTMLBody = File.ReadAllText(HTMLTemplatePath);
TextBody = File.ReadAllText(TextTemplatePath);

HTMLBody = HTMLBody.Replace(["[BODY]", content);
TextBody = HTMLBody.Replace(["[BODY]", content);

// Create email code
MailMessage m = new MailMessage();

m.From = new MailAddress("[email protected]", "display name");
m.To.Add("[email protected]");
m.Subject = "subject";

AlternateView plain = AlternateView.CreateAlternateViewFromString(_EmailBody + text, new System.Net.Mime.ContentType("text/plain"));
AlternateView html = AlternateView.CreateAlternateViewFromString(_EmailBody + body, new System.Net.Mime.ContentType("text/html"));
mail.AlternateViews.Add(plain);
mail.AlternateViews.Add(html);

SmtpClient smtp = new SmtpClient("server");
smtp.Send(m);

I'm not familiar with the specific issue, but you could stick a div, etc inside the td and set overflow on that.

I have faced with the same issue. The resolve: - Window-->Preferences-->Java-->Installed JREs-->Add... - Right click on your project-->Build Path-->Configure Build Path-->Add library-->JRE system library-->next-->WorkSpace Default JRE

For Scroll View:

if after adding android:windowSoftInputMode="stateHidden|adjustPan" in your Android Manifest and still does not work.

It may be affected because when the keyboard appears, it will be into a scroll view and if your button/any objects is not in your scroll view then the objects will follow the keyboard and move its position.

Check out your xml where your button is and make sure it is under your scroll View bracket and not out of it.

Hope this helps out. :D

specify your marks:

List<Double> marks = new ArrayList<Double>();

This is called generics.

Apache Commons users can use ThreadUtils. The current implementation uses the walk the thread group approach previously outlined.

for (Thread t : ThreadUtils.getAllThreads()) {
      System.out.println(t.getName() + ", " + t.isDaemon());
}

diplay: flex; for it's container and margin:auto; for it's item works perfect.

NOTE: You have to setup the width and height to see the effect.

#container{_x000D_
  width: 100%; /*width needs to be setup*/_x000D_
  height: 150px; /*height needs to be setup*/_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.item{_x000D_
  margin: auto; /*These will make the item in center*/_x000D_
  background-color: #CCC;_x000D_
}

<div id="container">_x000D_
   <div class="item">CENTER</div>_x000D_
</div>

void foo<TOne, TTwo>() 
   where TOne : BaseOne
   where TTwo : BaseTwo

That's a good question! You may get into troubles if you invoke API that uses generics and want to assign or return that result with a different subtype of the generic type. Java 8 helps to transform:

    List<String> input = new LinkedList<>(Arrays.asList("a", "b", "c"));
    List<CharSequence> result;
    
//    result = input; // <-- Type mismatch: cannot convert from List<String> to List<CharSequence>
    result = input.stream().collect(Collectors.toList());
    
    System.out.println(result);
