Here is the answer from @mvanle, converted to Scala: scala> val Array(javaVerPrefix, javaVerMajor, javaVerMinor, _, _) = System.getProperty("java.runtime.version").split("\\.|_|-b") javaVerPrefix: String = 1 javaVerMajor: String = 8 javaVerMinor: String = 0

DesiredCapabilities are options that you can use to customize and configure a browser session.

You can read more about them here!

Unless the variable k is defined, that's probably what's causing your trouble. Something like this will do what you want:

var new_tweets = { };

new_tweets.k = { };

new_tweets.k.tweet_id = 98745521;
new_tweets.k.user_id = 54875;

new_tweets.k.data = { };

new_tweets.k.data.in_reply_to_screen_name = 'other_user';
new_tweets.k.data.text = 'tweet text';

// Will create the JSON string you're looking for.
var json = JSON.stringify(new_tweets);

You can also do it all at once:

var new_tweets = {
  k: {
    tweet_id: 98745521,
    user_id: 54875,
    data: {
      in_reply_to_screen_name: 'other_user',
      text: 'tweet_text'
    }
  }
}

Call it like this:

foo(*ob);

Note that there is no casting going on here, as suggested in your question title. All we have done is de-referenced the pointer to the object which we then pass to the function.

You could iterate backwards and remove as you go through the ArrayList. This has the advantage of subsequent elements not needing to shift and is easier to program than moving forwards.

Here are some exchange APIs with PHP example.

[ Open Exchange Rates API ]

Provides 1,000 requests per month free. You must register and grab the App ID. The base currency USD for free account. Check the supported currencies and documentation.

// open exchange URL // valid app_id * REQUIRED *
$exchange_url = 'https://openexchangerates.org/api/latest.json';
$params = array(
    'app_id' => 'YOUR_APP_ID'
);

// make cURL request // parse JSON
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => $exchange_url . '?' . http_build_query($params),
    CURLOPT_RETURNTRANSFER => true
));
$response = json_decode(curl_exec($curl));
curl_close($curl);

if (!empty($response->rates)) {
    // convert 150 USD to JPY ( Japanese Yen )
    echo $response->rates->JPY * 150;
}

150 USD = 18039.09015 JPY

[ Currency Layer API ]

Provides 1,000 requests per month free. You must register and grab the Access KEY. Custom base currency is not supported in free account. Check the documentation.

$exchange_url = 'http://apilayer.net/api/live';
$params = array(
    'access_key' => 'YOUR_ACCESS_KEY',
    'source' => 'USD',
    'currencies' => 'JPY',
    'format' => 1 // 1 = JSON
);

// make cURL request // parse JSON
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => $exchange_url . '?' . http_build_query($params),
    CURLOPT_RETURNTRANSFER => true
));
$response = json_decode(curl_exec($curl));
curl_close($curl);

if (!empty($response->quotes)) {
    // convert 150 USD to JPY ( Japanese Yen )
    echo '150 USD = ' . $response->quotes->USDJPY * 150 . ' JPY';
}

150 USD = 18036.75045 JPY

I just wanted to add to this discussion that I am just compiling on VS and GCC, and used to use include guards. I have now switched to #pragma once, and the only reason for me is not performance or portability or standard as I don't really care what is standard as long as VS and GCC support it, and that is that:

#pragma once reduces possibilities for bugs.

It is all too easy to copy and paste a header file to another header file, modify it to suit ones needs, and forget to change the name of the include guard. Once both are included, it takes you a while to track down the error, as the error messages aren't necessarily clear.

This is for es2015 and above as far as I know. There are 'cleaner' options with ES6 but this a great way to do it (with TypeScript).

let values: any[] = [];
const distinct = (value: any, index: any, self: any) => {
    return self.indexOf(value) === index;
};
values = values.filter(distinct);

Nothing. It was added to the C99 standard.

Both are Creational patterns, to create Object.

1) Factory Pattern - Assume, you have one super class and N number of sub classes. The object is created depends on which parameter/value is passed.

2) Builder pattern - to create complex object.

Ex: Make a Loan Object. Loan could be house loan, car loan ,
    education loan ..etc. Each loan will have different interest rate, amount ,  
    duration ...etc. Finally a complex object created through step by step process.

You can declare SqlConnection and SqlCommand instances at global level so that you can use it through out the class. Connection string is in Web.Config.

SqlConnection sqlConn = new SqlConnection(WebConfigurationManager.ConnectionStrings["SqlConnector"].ConnectionString);
SqlCommand sqlcomm = new SqlCommand();

Now you can use the below method to pass values to Stored Procedure and get the DataSet.

public DataSet GetDataSet(string paramValue)
{
    sqlcomm.Connection = sqlConn;
    using (sqlConn)
    {
        try
        {
            using (SqlDataAdapter da = new SqlDataAdapter())
            {  
                // This will be your input parameter and its value
                sqlcomm.Parameters.AddWithValue("@ParameterName", paramValue);

                // You can retrieve values of `output` variables
                var returnParam = new SqlParameter
                {
                    ParameterName = "@Error",
                    Direction = ParameterDirection.Output,
                    Size = 1000
                };
                sqlcomm.Parameters.Add(returnParam);
                // Name of stored procedure
                sqlcomm.CommandText = "StoredProcedureName";
                da.SelectCommand = sqlcomm;
                da.SelectCommand.CommandType = CommandType.StoredProcedure;

                DataSet ds = new DataSet();
                da.Fill(ds);                            
            }
        }
        catch (SQLException ex)
        {
            Console.WriteLine("SQL Error: " + ex.Message);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }
    return new DataSet();
}

The following is the sample of connection string in config file

<connectionStrings>
    <add name="SqlConnector"
         connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=YourDatabaseName;User id=YourUserName;Password=YourPassword"
         providerName="System.Data.SqlClient" />
</connectionStrings>

There are some important issues that I think all of the existing answers have missed.

Weak typing means allowing access to the underlying representation. In C, I can create a pointer to characters, then tell the compiler I want to use it as a pointer to integers:

char sz[] = "abcdefg";
int *i = (int *)sz;

On a little-endian platform with 32-bit integers, this makes i into an array of the numbers 0x64636261 and 0x00676665. In fact, you can even cast pointers themselves to integers (of the appropriate size):

intptr_t i = (intptr_t)&sz;

And of course this means I can overwrite memory anywhere in the system.*

char *spam = (char *)0x12345678
spam[0] = 0;

_{* Of course modern OS's use virtual memory and page protection so I can only overwrite my own process's memory, but there's nothing about C itself that offers such protection, as anyone who ever coded on, say, Classic Mac OS or Win16 can tell you.}

Traditional Lisp allowed similar kinds of hackery; on some platforms, double-word floats and cons cells were the same type, and you could just pass one to a function expecting the other and it would "work".

Most languages today aren't quite as weak as C and Lisp were, but many of them are still somewhat leaky. For example, any OO language that has an unchecked "downcast",* that's a type leak: you're essentially telling the compiler "I know I didn't give you enough information to know this is safe, but I'm pretty sure it is," when the whole point of a type system is that the compiler always has enough information to know what's safe.

_{* A checked downcast doesn't make the language's type system any weaker just because it moves the check to runtime. If it did, then subtype polymorphism (aka virtual or fully-dynamic function calls) would be the same violation of the type system, and I don't think anyone wants to say that.}

Very few "scripting" languages are weak in this sense. Even in Perl or Tcl, you can't take a string and just interpret its bytes as an integer.* But it's worth noting that in CPython (and similarly for many other interpreters for many languages), if you're really persistent, you can use ctypes to load up libpython, cast an object's id to a POINTER(Py_Object), and force the type system to leak. Whether this makes the type system weak or not depends on your use cases—if you're trying to implement an in-language restricted execution sandbox to ensure security, you do have to deal with these kinds of escapes…

_{* You can use a function like struct.unpack to read the bytes and build a new int out of "how C would represent these bytes", but that's obviously not leaky; even Haskell allows that.}

Meanwhile, implicit conversion is really a different thing from a weak or leaky type system.

Every language, even Haskell, has functions to, say, convert an integer to a string or a float. But some languages will do some of those conversions for you automatically—e.g., in C, if you call a function that wants a float, and you pass it in int, it gets converted for you. This can definitely lead to bugs with, e.g., unexpected overflows, but they're not the same kinds of bugs you get from a weak type system. And C isn't really being any weaker here; you can add an int and a float in Haskell, or even concatenate a float to a string, you just have to do it more explicitly.

And with dynamic languages, this is pretty murky. There's no such thing as "a function that wants a float" in Python or Perl. But there are overloaded functions that do different things with different types, and there's a strong intuitive sense that, e.g., adding a string to something else is "a function that wants a string". In that sense, Perl, Tcl, and JavaScript appear to do a lot of implicit conversions ("a" + 1 gives you "a1"), while Python does a lot fewer ("a" + 1 raises an exception, but 1.0 + 1 does give you 2.0*). It's just hard to put that sense into formal terms—why shouldn't there be a + that takes a string and an int, when there are obviously other functions, like indexing, that do?

_{* Actually, in modern Python, that can be explained in terms of OO subtyping, since isinstance(2, numbers.Real) is true. I don't think there's any sense in which 2 is an instance of the string type in Perl or JavaScript… although in Tcl, it actually is, since everything is an instance of string.}

Finally, there's another, completely orthogonal, definition of "strong" vs. "weak" typing, where "strong" means powerful/flexible/expressive.

For example, Haskell lets you define a type that's a number, a string, a list of this type, or a map from strings to this type, which is a perfectly way to represent anything that can be decoded from JSON. There's no way to define such a type in Java. But at least Java has parametric (generic) types, so you can write a function that takes a List of T and know that the elements are of type T; other languages, like early Java, forced you to use a List of Object and downcast. But at least Java lets you create new types with their own methods; C only lets you create structures. And BCPL didn't even have that. And so on down to assembly, where the only types are different bit lengths.

So, in that sense, Haskell's type system is stronger than modern Java's, which is stronger than earlier Java's, which is stronger than C's, which is stronger than BCPL's.

So, where does Python fit into that spectrum? That's a bit tricky. In many cases, duck typing allows you to simulate everything you can do in Haskell, and even some things you can't; sure, errors are caught at runtime instead of compile time, but they're still caught. However, there are cases where duck typing isn't sufficient. For example, in Haskell, you can tell that an empty list of ints is a list of ints, so you can decide that reducing + over that list should return 0*; in Python, an empty list is an empty list; there's no type information to help you decide what reducing + over it should do.

_{* In fact, Haskell doesn't let you do this; if you call the reduce function that doesn't take a start value on an empty list, you get an error. But its type system is powerful enough that you could make this work, and Python's isn't.}

SOLVED:

The above did not help. Then I simply installed sklearn from within Jypyter-lab, even though sklearn 0.0 shows in 'pip list':

!pip install sklearn
import sklearn

What I learned later is that pip installs, in my case, packages in a different folder than Jupyter. This can be seen by executing:

import sys
print(sys.path)

Once from within Jupyter_lab notebook, and once from the command line using 'py notebook.py'.

In my case Jupyter list of paths where subfolders of 'anaconda' whereas Python list where subfolders of c:\users[username]...

I have found this works ONLY in Chrome (where it's red) and not Safari and all other browsers (where it's green)...

put them both inside a div with nowrap.

<div style="white-space:nowrap">

There is the question whether we want to differentiate between cases:

1. "phone" : "" = the value is empty

2. "phone" : null = the value for "phone" was not set yet

If we want differentiate I would use null for this. Otherwise we would need to add a new field like "isAssigned" or so. This is an old Database issue.

try with this.

Protected Sub SqlDataSource_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles SqlDataSource.Selecting

    e.Command.CommandText = "SELECT [ImageID],[ImagePath] FROM [TblImage] where IsActive = 1"

    End Sub

var = raw_input("Please enter something: ")
print "you entered", var

Or for Python 3:

var = input("Please enter something: ")
print("You entered: " + var)

If you're using ksh or bash they both support IO redirection to/from a socket using the /dev/tcp/IP/PORT construct. In this Korn shell example I am redirecting no-op's (:) std-in from a socket:

W$ python -m SimpleHTTPServer &
[1]     16833
Serving HTTP on 0.0.0.0 port 8000 ...
W$ : </dev/tcp/127.0.0.1/8000

The shell prints an error if the socket is not open:

W$ : </dev/tcp/127.0.0.1/8001
ksh: /dev/tcp/127.0.0.1/8001: cannot open [Connection refused]

You can therefore use this as the test in an if condition:

SERVER=127.0.0.1 PORT=8000
if (: < /dev/tcp/$SERVER/$PORT) 2>/dev/null
then
    print succeeded
else
    print failed
fi

The no-op is in a subshell so I can throw std-err away if the std-in redirection fails.

I often use /dev/tcp for checking the availability of a resource over HTTP:

W$ print arghhh > grr.html
W$ python -m SimpleHTTPServer &
[1]     16863
Serving HTTP on 0.0.0.0 port 8000 ...
W$ (print -u9 'GET /grr.html HTTP/1.0\n';cat <&9) 9<>/dev/tcp/127.0.0.1/8000
HTTP/1.0 200 OK
Server: SimpleHTTP/0.6 Python/2.6.1
Date: Thu, 14 Feb 2013 12:56:29 GMT
Content-type: text/html
Content-Length: 7
Last-Modified: Thu, 14 Feb 2013 12:55:44 GMT

arghhh
W$ 

This one-liner opens file descriptor 9 for reading from and writing to the socket, prints the HTTP GET to the socket and uses cat to read from the socket.

Even though Logger.log() is technically the correct way to output something to the console, it has a few annoyances:

1. The output can be an unstructured mess and hard to quickly digest.
2. You have to first run the script, then click View / Logs, which is two extra clicks (one if you remember the Ctrl+Enter keyboard shortcut).
3. You have to insert Logger.log(playerArray), and then after debugging you'd probably want to remove Logger.log(playerArray), hence an additional 1-2 more steps.
4. You have to click on OK to close the overlay (yet another extra click).

Instead, whenever I want to debug something I add breakpoints (click on line number) and press the Debug button (bug icon). Breakpoints work well when you are assigning something to a variable, but not so well when you are initiating a variable and want to peek inside of it at a later point, which is similar to what the op is trying to do. In this case, I would force a break condition by entering "x" (x marks the spot!) to throw a run-time error:

Compare with viewing Logs:

The Debug console contains more information and is a lot easier to read than the Logs overlay. One minor benefit with this method is that you never have to worry about polluting your code with a bunch of logging commands if keeping clean code is your thing. Even if you enter "x", you are forced to remember to remove it as part of the debugging process or else your code won't run (built-in cleanup measure, yay).

Just use this for the closing tag:

  @:</tr>

And leave your if/else as is.

Seems like the if statement doesn't wanna' work.

It works fine. You're working in 2 language-spaces here, it seems only proper not to split open/close sandwiches over the border.

Character.getNumericValue(c)

The java.lang.Character.getNumericValue(char ch) returns the int value that the specified Unicode character represents. For example, the character '\u216C' (the roman numeral fifty) will return an int with a value of 50.

The letters A-Z in their uppercase ('\u0041' through '\u005A'), lowercase ('\u0061' through '\u007A'), and full width variant ('\uFF21' through '\uFF3A' and '\uFF41' through '\uFF5A') forms have numeric values from 10 through 35. This is independent of the Unicode specification, which does not assign numeric values to these char values.

This method returns the numeric value of the character, as a nonnegative int value;

-2 if the character has a numeric value that is not a nonnegative integer;

-1 if the character has no numeric value.

And here is the link.

You will need to link to the file relative to the file that includes eventManager.php (Page A)

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.
debug1: connect to address 173.194.43.20 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.19] port 22.
debug1: connect to address 173.194.43.19 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.18] port 22.
debug1: connect to address 173.194.43.18 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.17] port 22.
debug1: connect to address 173.194.43.17 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.16] port 22.
debug1: connect to address 173.194.43.16 port 22: Connection timed out
ssh: connect to host www.google.com port 22: Connection timed out

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

This might be trivial and not related to the OP's question, but I often made this mistaken at the beginning when I was learning scripting

VAR_NAME = $(hostname)
echo "the hostname is ${VAR_NAME}"  

This will produce 'command not found' response. The correct way is to eliminate the spaces

VAR_NAME=$(hostname)

You should use html autofocus for this:

<input *ngIf="show" #search type="text" autofocus /> 

Note: if your component is persisted and reused it will only autofocus the first time the fragment is attached. This can be overcome by having a global dom listener that checks for autofocus attribute inside a dom fragment when it is attached and then reapplying it or focus via javascript.

Use a timer. Keep in mind that .NET comes with a number of different timers. This article covers the differences.

Most of the time i'm doing something like this :

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {isHidden: false};
    this.onPress = this.onPress.bind(this);
  }
  onPress() {
    this.setState({isHidden: !this.state.isHidden})
  }
  render() {
    return (
      <View style={styles.myStyle}>

        {this.state.isHidden ? <ToHideAndShowComponent/> : null}

        <Button title={this.state.isHidden ? "SHOW" : "HIDE"} onPress={this.onPress} />
      </View>
    );
  }
}

If you're kind of new to programming, this line must be strange to you :

{this.state.isHidden ? <ToHideAndShowComponent/> : null}

This line is equivalent to

if (this.state.isHidden)
{
  return ( <ToHideAndShowComponent/> );
}
else
{
  return null;
}

But you can't write an if/else condition in JSX content (e.g. the return() part of a render function) so you'll have to use this notation.

This little trick can be very useful in many cases and I suggest you to use it in your developments because you can quickly check a condition.

Regards,

That chart is not showing percents. "#90" is not "90%". That chart shows the hexadecimal to decimal conversion. The hex number 90 (typically represented as 0x90) is equivalent to the decimal number 144.

Hexadecimal numbers are base-16, so each digit is a value between 0 and F. The maximum value for a two byte hex value (such as the transparency of a color) is 0xFF, or 255 in decimal. Thus 100% is 0xFF.

According to Pure CSS Scrollable Table with Fixed Header , I wrote a DEMO to easily fix the header by setting overflow:auto to the tbody.

table thead tr{
    display:block;
}

table th,table td{
    width:100px;//fixed width
}


table  tbody{
  display:block;
  height:200px;
  overflow:auto;//set tbody to auto
}

None of the answers here worked for me in Chrome. AAverin on GitHub has created some useful Javascript for this purpose and this worked for me:

Just add the js to your code and add the class 'splitForPrint' to your table and it will neatly split the table into multiple pages and add the table header to each page.

Dont know whether I should put this as answer or not...

I used @Zeeshan0026's solution to draw the path...and the problem was that if I draw path once, and then I do try to draw path once again, both two paths show and this continues...paths showing even when markers were deleted... while, ideally, old paths' shouldn't be there once new path is drawn / markers are deleted..

going through some other question over SO, I had the following solution

I add the following function in Zeeshan's class

 public void clearRoute(){

         for(Polyline line1 : polylines)
         {
             line1.remove();
         }

         polylines.clear();

     }

in my map activity, before drawing the path, I called this function.. example usage as per my app is

private Route rt;

rt.clearRoute();

            if (src == null) {
                Toast.makeText(getApplicationContext(), "Please select your Source", Toast.LENGTH_LONG).show();
            }else if (Destination == null) {
                Toast.makeText(getApplicationContext(), "Please select your Destination", Toast.LENGTH_LONG).show();
            }else if (src.equals(Destination)) {
                Toast.makeText(getApplicationContext(), "Source and Destinatin can not be the same..", Toast.LENGTH_LONG).show();
            }else{

                rt.drawRoute(mMap, MapsMainActivity.this, src,
                        Destination, false, "en");
            }

you can use rt.clearRoute(); as per your requirements.. Hoping that it will save a few minutes of someone else and will help some beginner in solving this issue..

                            Destination = null;

Edit 2 as per comments

usage :

//variables as data members
GoogleMap mMap;
private Route rt;
static LatLng src;
static LatLng Destination;
//MapsMainActivity is my activity
//false for interim stops for traffic, google
// en language for html description returned

rt.drawRoute(mMap, MapsMainActivity.this, src,
                            Destination, false, "en");

Something like:

select t1.name, t2.image_id, t3.path
from table1 t1 inner join table2 t2 on t1.person_id = t2.person_id
inner join table3 t3 on t2.image_id=t3.image_id

  //function to find vowel
const vowel = (str)=>{
  //these are vowels we want to check for
  const check = ['a','e','i','o','u'];
  //keep track of vowels
  var count = 0;
  for(let char of str.toLowerCase())
  {
    //check if each character in string is in vowel array
    if(check.includes(char)) count++;
  }
  return count;
}

console.log(vowel("hello there"));

By using css you can add your icon via Unicode

content: '\f144';
font-family: FontAwesome;

This will work

Any modern solution to this problem? I worked around it with:

    order = sorted([ job['priority'] for job in self.joblist ])
    sorted_joblist = []
    while order:
        min_priority = min(order)
        for job in self.joblist:
            if job['priority'] == min_priority:
                sorted_joblist += [ job ]
                order.remove(min_priority)
    self.joblist = sorted_joblist

The joblist is formatted as: joblist = [ { 'priority' : 3, 'name' : 'foo', ... }, { 'priority' : 1, 'name' : 'bar', ... } ]

• Basically I create a list (order) with all the elements by which I want to sort the dict
• then I iterate this list and the dict, when I find the item on the dict I send it to a new dict and remove the item from 'order'.

Seems to be working, but I suppose there are better solutions.

You should use NVARCHAR anytime you have to store multiple languages. I believe you have to use it for the Asian languages but don't quote me on it.

Here's the problem if you take Russian for example and store it in a varchar, you will be fine so long as you define the correct code page. But let's say your using a default english sql install, then the russian characters will not be handled correctly. If you were using NVARCHAR() they would be handled properly.

Edit

Ok let me quote MSDN and maybee I was to specific but you don't want to store more then one code page in a varcar column, while you can you shouldn't

When you deal with text data that is stored in the char, varchar, varchar(max), or text data type, the most important limitation to consider is that only information from a single code page can be validated by the system. (You can store data from multiple code pages, but this is not recommended.) The exact code page used to validate and store the data depends on the collation of the column. If a column-level collation has not been defined, the collation of the database is used. To determine the code page that is used for a given column, you can use the COLLATIONPROPERTY function, as shown in the following code examples:

Here's some more:

This example illustrates the fact that many locales, such as Georgian and Hindi, do not have code pages, as they are Unicode-only collations. Those collations are not appropriate for columns that use the char, varchar, or text data type

So Georgian or Hindi really need to be stored as nvarchar. Arabic is also a problem:

Another problem you might encounter is the inability to store data when not all of the characters you wish to support are contained in the code page. In many cases, Windows considers a particular code page to be a "best fit" code page, which means there is no guarantee that you can rely on the code page to handle all text; it is merely the best one available. An example of this is the Arabic script: it supports a wide array of languages, including Baluchi, Berber, Farsi, Kashmiri, Kazakh, Kirghiz, Pashto, Sindhi, Uighur, Urdu, and more. All of these languages have additional characters beyond those in the Arabic language as defined in Windows code page 1256. If you attempt to store these extra characters in a non-Unicode column that has the Arabic collation, the characters are converted into question marks.

Something to keep in mind when you are using Unicode although you can store different languages in a single column you can only sort using a single collation. There are some languages that use latin characters but do not sort like other latin languages. Accents is a good example of this, I can't remeber the example but there was a eastern european language whose Y didn't sort like the English Y. Then there is the spanish ch which spanish users expet to be sorted after h.

All in all with all the issues you have to deal with when dealing with internalitionalization. It is my opinion that is easier to just use Unicode characters from the start, avoid the extra conversions and take the space hit. Hence my statement earlier.

You asked: information in AWS console about how much disk space is using on my S3 cloud?

I so to the Billing Dashboard and check the S3 usage in the current bill.

They give you the information - MTD - in Gb to 6 decimal points, IOW, to the Kb level.

It's broken down by region, but adding them up (assuming you use more than one region) is easy enough.

^{BTW: You may need specific IAM permissions to get to the Billing information.}

you want to use include_once() or require_once(). The other option would be to create an additional file with all your class includes in the correct order so they don't need to call includes themselves:

"classes.php"

include 'database.php';
include 'parent.php';
include 'child1.php';
include 'child2.php';

Then you just need:

require_once('classes.php');

Drag the constraint into your VC as an IBOutlet. Then you can change its associated value (and other properties; check the documentation):

@IBOutlet myConstraint : NSLayoutConstraint!
@IBOutlet myView : UIView!

func updateConstraints() {
    // You should handle UI updates on the main queue, whenever possible
    DispatchQueue.main.async {
        self.myConstraint.constant = 10
        self.myView.layoutIfNeeded()
    }
}

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

this can be done this way

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

I seem to remember my computer science professor say back in the day that all problems that have recursive solutions also have iterative solutions. He says that a recursive solution is usually slower, but they are frequently used when they are easier to reason about and code than iterative solutions.

However, in the case of more advanced recursive solutions, I don't believe that it will always be able to implement them using a simple for loop.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

Thanks justingrammens! That worked for me, I managed to share the cookie within my DefaultHttpClient requests and WebView activity:

//------- Native request activity
private DefaultHttpClient httpClient;
public static Cookie cookie = null;

//After Login
List<Cookie> cookies = httpClient.getCookieStore().getCookies();
for (int i = 0; i < cookies.size(); i++) {
    cookie = cookies.get(i);
}

//------- Web Browser activity
Cookie sessionCookie = myapp.cookie;
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
if (sessionCookie != null) {
    cookieManager.removeSessionCookie();
    String cookieString = sessionCookie.getName() + "=" + sessionCookie.getValue() + "; domain=" + sessionCookie.getDomain();
    cookieManager.setCookie(myapp.domain, cookieString);
    CookieSyncManager.getInstance().sync();
}   

The best source of information is the official Python tutorial on list comprehensions. List comprehensions are nearly the same as for loops (certainly any list comprehension can be written as a for-loop) but they are often faster than using a for loop.

Look at this longer list comprehension from the tutorial (the if part filters the comprehension, only parts that pass the if statement are passed into the final part of the list comprehension (here (x,y)):

>>> [(x, y) for x in [1,2,3] for y in [3,1,4] if x != y]
[(1, 3), (1, 4), (2, 3), (2, 1), (2, 4), (3, 1), (3, 4)]

It's exactly the same as this nested for loop (and, as the tutorial says, note how the order of for and if are the same).

>>> combs = []
>>> for x in [1,2,3]:
...     for y in [3,1,4]:
...         if x != y:
...             combs.append((x, y))
...
>>> combs
[(1, 3), (1, 4), (2, 3), (2, 1), (2, 4), (3, 1), (3, 4)]

The major difference between a list comprehension and a for loop is that the final part of the for loop (where you do something) comes at the beginning rather than at the end.

On to your questions:

What type must object be in order to use this for loop structure?

An iterable. Any object that can generate a (finite) set of elements. These include any container, lists, sets, generators, etc.

What is the order in which i and j are assigned to elements in object?

They are assigned in exactly the same order as they are generated from each list, as if they were in a nested for loop (for your first comprehension you'd get 1 element for i, then every value from j, 2nd element into i, then every value from j, etc.)

Can it be simulated by a different for loop structure?

Yes, already shown above.

Can this for loop be nested with a similar or different structure for loop? And how would it look?

Sure, but it's not a great idea. Here, for example, gives you a list of lists of characters:

[[ch for ch in word] for word in ("apple", "banana", "pear", "the", "hello")]

Simplest way is:

bgSound = new Audio("sounds/background.mp3");
bgSound.loop = true;
bgSound.play();

let dateTimeStamp = NSDate(timeIntervalSince1970:Double(currentTimeInMiliseconds())/1000)  //UTC time  //YOUR currentTimeInMiliseconds METHOD
let dateFormatter = NSDateFormatter()
dateFormatter.timeZone = NSTimeZone.localTimeZone() 
dateFormatter.dateFormat = "yyyy-MM-dd"
dateFormatter.dateStyle = NSDateFormatterStyle.FullStyle
dateFormatter.timeStyle = NSDateFormatterStyle.ShortStyle


let strDateSelect = dateFormatter.stringFromDate(dateTimeStamp)
print("Local Time", strDateSelect) //Local time


let dateFormatter2 = NSDateFormatter()
dateFormatter2.timeZone = NSTimeZone(name: "UTC") as NSTimeZone!
dateFormatter2.dateFormat = "yyyy-MM-dd"

let date3 = dateFormatter.dateFromString(strDateSelect)
print("DATE",date3)

If a website's directory does NOT have an "index...." file, AND .htaccess has NOT been used to block access to the directory itself, then Apache will create an "index of" page for that directory. You can save that page, and its icons, using "Save page as..." along with the "Web page, complete" option (Firefox example). If you own the website, temporarily rename any "index...." file, and reference the directory locally. Then restore your "index...." file.

It is quite easy with the tool XrayInterface. Just define the missing getters/setters, e.g.

interface BetterDesigned {
  Hashtable getStuffIWant(); //is mapped by convention to stuffIWant
}

and xray your poor designed project:

IWasDesignedPoorly obj = new IWasDesignedPoorly();
BetterDesigned better = ...;
System.out.println(better.getStuffIWant());

Internally this relies on reflection.

Like it was already discussed, the files were probably flagged with "assume-unchanged", which basicly tells git that you will not modify the files, so it doesnt need to track changes with them. However this may be affecting multiple files, and if its a large workspace you might not want to check them all one by one. In that case you can try: git update-index --really-refresh

according to the docs:

Like --refresh, but checks stat information unconditionally, without regard to the "assume unchanged" setting.

It will basicly force git to track changes of all files regardless of the "assume-unchanged" flags.

Using:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

...will show you the ctn_no value(s) that have duplicates in your table. Adding criteria to the WHERE will allow you to further tune what duplicates there are:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
   WHERE t.s_ind = 'Y'
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

If you want to see the other column values associated with the duplicate, you'll want to use a self join:

SELECT x.*
  FROM YOUR_TABLE x
  JOIN (SELECT t.ctn_no
          FROM YOUR_TABLE t
      GROUP BY t.ctn_no
        HAVING COUNT(t.ctn_no) > 1) y ON y.ctn_no = x.ctn_no

Watch out if you want to retrieve a boolean value from a hidden field!

For example:

<input type="hidden" id="SomeBoolean" value="False"/>

(An input like this will be rendered by ASP MVC if you use @Html.HiddenFor(m => m.SomeBoolean).)

Then the following will return a string 'False', not a JS boolean!

var notABool = $('#SomeBoolean').val();

If you want to use the boolean for some logic, use the following instead:

var aBool = $('#SomeBoolean').val() === 'True';
if (aBool) { /* ...*/ }

Note: Posted this answer because OP later stated in comments that they need to select the last two elements, not just the second to last one.

The :nth-child CSS3 selector is in fact more capable than you ever imagined!

For example, this will select the last 2 elements of #container:

#container :nth-last-child(-n+2) {}

But this is just the beginning of a beautiful friendship.

• :nth-child Browser Support

#container :nth-last-child(-n+2) {
  background-color: cyan;
}

<div id="container">
 <div>a</div>
 <div>b</div>
 <div>SELECT THIS</div>
 <div>SELECT THIS</div>
</div>

For objects you can nest the queries:

DB::table('orders')->find(DB::table('orders')->max('id'));

So the inside query looks up the max id in the table and then passes that to the find, which gets you back the object.

In MVVM (wich makes a lot of things a lot easier - you should try it) you would have two properties in your ViewModel Text that is bound to your TextBox and you would have an ICommand property Apply (or similar) that is bound to the button:

<Button Command="Apply">Apply</Button>

The ICommand interface has a Method CanExecute that is where you return true if (!string.IsNullOrWhiteSpace(this.Text). The rest is done by WPF for you (enabling/disabling, executing the actual command on click).

The linked article explains it in detail.

In a different thread Justin suggests that the fastest way is to use strtok()

 $url = strtok($url, '?');

See his full answer with speed tests as well here: https://stackoverflow.com/a/1251650/452515

Well, here is my solution how to raise an event only once:

FileSystemWatche? watcher = new FileSystemWatcher();

//'path' - path to the file that has been modified.
watcher.Changed += (s, e) => FileChanged(path);

here is implementation of FileChanged

//count is our counter to triger when we can raise and when not.
private int count = 0;
private void FileChanged(string path)
{
   if (count % 2 == 0)
     {
       //code here
     }

     count ++;
}

I had this problem in Visual Studio 2013. I reinstalled NuGet Package Manager:

https://marketplace.visualstudio.com/items?itemName=NuGetTeam.NuGetPackageManagerforVisualStudio2013

Why don't you use a List<People> instead of a List<List<string>> ?

Try giving the full path to apache2ctl.

In Bash:

if [[ ( $g == 1 && $c == 123 ) || ( $g == 2 && $c == 456 ) ]]

Array.prototype.removeAt = function(id) {
    for (var item in this) {
        if (this[item].id == id) {
            this.splice(item, 1);
            return true;
        }
    }
    return false;
}

This should do the trick, jsfiddle

A . in regex is a metacharacter, it is used to match any character. To match a literal dot, you need to escape it, so \.

If you want nice json without hardcoding attributes into your service classes,

use <webHttp defaultOutgoingResponseFormat="Json"/> in your behavior config

You can use a class that works much like a builder to contain your optional values like this.

public class Options {
    private String someString = "default value";
    private int someInt= 0;
    public Options setSomeString(String someString) {
        this.someString = someString;
        return this;
    }
    public Options setSomeInt(int someInt) {
        this.someInt = someInt;
        return this;
    }
}

public static void foo(Consumer<Options> consumer) {
    Options options = new Options();
    consumer.accept(options);
    System.out.println("someString = " + options.someString + ", someInt = " + options.someInt);
}

Use like

foo(o -> o.setSomeString("something").setSomeInt(5));

Output is

someString = something, someInt = 5

To skip all the optional values you'd have to call it like foo(o -> {}); or if you prefer, you can create a second foo() method that doesn't take the optional parameters.

Using this approach, you can specify optional values in any order without any ambiguity. You can also have parameters of different classes unlike with varargs. This approach would be even better if you can use annotations and code generation to create the Options class.

For Angular Version 11+

Configuration

The styles and scripts options in your angular.json configuration now allow to reference a package directly:

before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]

          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","bootstrap/dist/css/bootstrap.min.css"

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

Angular Version 10 and below

Angular v6 Onwards

CLI projects in angular 6 onwards will be using angular.json instead of .angular-cli.json for build and project configuration.

Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs

. {
  "projects": {
    "my-project-name": {
      "projectType": "application",
      "architect": {
        "build": {
          "configurations": {
            "production": {},
            "demo": {},
            "staging": {},
          }
        },
        "serve": {},
        "extract-i18n": {},
        "test": {},
      }
    },
    "my-project-name-e2e": {}
  },
}

OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap are dependent on jQuery. So you need the jQuery JavaScript library file too.

In your angular.json add the file paths to the styles and scripts array in under build target
NOTE: Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json. As of v6 the location of the file changed to angular.json. Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash

i.e you can provide an absolute path instead of a relative path

In .angular-cli.json file Path was "../node_modules/"
In angular.json it is "node_modules/"

 "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"
               
            ],
            "scripts": ["node_modules/jquery/dist/jquery.min.js",
                       "node_modules/bootstrap/dist/js/bootstrap.min.js"]
          },

OPTION 2
Add files from CDN (Content Delivery Network) to your project CDN LINK

Open file src/index.html and insert

the <link> element at the end of the head section to include the Bootstrap CSS file
a <script> element to include jQuery at the bottom of the body section
a <script> element to include Popper.js at the bottom of the body section
a <script> element to include the Bootstrap JavaScript file at the bottom of the body section

  <!doctype html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Angular</title>
      <base href="/">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <link rel="icon" type="image/x-icon" href="favicon.ico">

    </body>
    </html>

OPTION 3
Execute npm install bootstrap
In src/styles.css add the following line:

@import "~bootstrap/dist/css/bootstrap.css";

OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript

npm install --save @ng-bootstrap/ng-bootstrap

After Installation import it in your root module and register it in @NgModule imports` array

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

NOTE
ng-bootstrap requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save In your angular.json add the file paths to the styles array in under build target

   "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],

P.S Do Restart Your server

fapDaddy's answer using a macro pointed me in the right direction.

Here's precisely what worked for me.

1. Place the cursor after the first data item.

2. Click 'Macro > Start Recording' in the menu.

3. Type this sequence: Comma, Space, Delete, End.

4. Click 'Macro > Stop recording' in the menu.

5. Click 'Macro > Run a Macro Multiple Times...' in the menu.

6. Click 'Run until the end of file' and click 'Run'.

7. Remove any trailing characters.

8. Done!

(I just got this working, with my main issue being that I don't have a real internet hostname, so answering this question in case it helps someone)

You need to specify a hostname with HELO. Even so, you should get an error, so Postfix is probably not running.

Also, the => is not a command. The '.' on a single line without any text around it is what tells Postfix that the entry is complete. Here are the entries I used:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: [email protected]
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

You should get a response like:

250 2.0.0 Ok: queued as 6E414C4643A

The email will probably end up in a junk folder. If it is not showing up, then you probably need to setup the 'Postfix on hosts without a real Internet hostname'. Here is the breakdown on how I completed that step on my Ubuntu box:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
[email protected]             [email protected]
[email protected]             [email protected]
@localdomain.local                [email protected]
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

Happy Trails

If your code doesn't cross filesystem boundaries, i.e. you're just working with one filesystem, then use java.io.File.separator.

This will, as explained, get you the default separator for your FS. As Bringer128 explained, System.getProperty("file.separator") can be overriden via command line options and isn't as type safe as java.io.File.separator.

The last one, java.nio.file.FileSystems.getDefault().getSeparator(); was introduced in Java 7, so you might as well ignore it for now if you want your code to be portable across older Java versions.

So, every one of these options is almost the same as others, but not quite. Choose one that suits your needs.

If you want to kill the Sticky Service,the following command NOT WORKING:

adb shell am force-stop <PACKAGE>
adb shell kill <PID>

The following command is WORKING:

adb shell pm disable <PACKAGE>

If you want to restart the app,you must run command below first:

adb shell pm enable <PACKAGE>

You have to provide 3 or 4 states in your btn_defaut.xml as a selector.

1. Pressed state
2. Default state
3. Focus state
4. Enabled state (Disable state with false indication; see comments)

You will provide effect and background for the states accordingly.

There have been a slew of recent changes in this arena, so I thought a fresh answer would be helpful.

To have a cookie sent by the browser to another site during a request the following criteria must be met:

• The Set-Cookie header from the target site must contain the SameSite=None and Secure labels. If Secure is not used the SameSite header will be ignored.
• The request must be made to a https endpoint, a requirement of the Secure flag.
• The XHRRequest must be made with withCredentials=true. If using $.ajax() this is accomplished with the xhrFields parameter (requiring jQuery=1.5.1+)
• The server must respond with Access-Control-Allow-Origin header that matches the request Origin header. (* will not be respected in this case)

A lot of people find their way to this post trying to do local development against a remote endpoint, which is possible if the above criteria are met.

If you have Bluetooth, Use twedge on windows and getblue app on android, they also have a few videos of it. It's made by TEC-IT. I've got it to work by setting the interface option to bluetooth server in TWedge and setting the output setting in getblue to Bluetooth client and selecting my computer from the Bluetooth devices list. Make sure your computer and phone is paired. Also to get the barcode as input set the action setting in TWedge to Keyboard Wedge. This will allow for you to first click the input text box on said form, then scan said product with your phone and wait a sec for the barcode number to be put into the text box. Using this method requires no php that doesn't already exist in your current form processing, just process the text box as usual and viola your phone scans bar codes, sends them to your pc via Bluetooth wirelessly, your computer inserts the barcode into whatever text field is selected in any application or website. Hope this helps.

Just go to File -> Settings -> select Project Interpreter under Project tab -> click on the small gear icon -> Add -> System Interpreter -> select the python version you want in the drop down menu

this seemed to work for me

If you need something fast and not very flexible

main.py:

import sys

first_name = sys.argv[1]
last_name = sys.argv[2]
print("Hello " + first_name + " " + last_name)

Then run python main.py James Smith

to produce the following output:

Hello James Smith

Wrapper class is a wrapper around a primitive data type. It represents primitive data types in their corresponding class instances e.g. a boolean data type can be represented as a Boolean class instance. All of the primitive wrapper classes in Java are immutable i.e. once assigned a value to a wrapper class instance cannot be changed further.

For the modification, you could use tag.text from xml. Here is snippet:

import xml.etree.ElementTree as ET

tree = ET.parse('country_data.xml')
root = tree.getroot()

for rank in root.iter('rank'):
    new_rank = int(rank.text) + 1
    rank.text = str(new_rank)
    
tree.write('output.xml')

The rank in the code is example of tag, which depending on your XML file contents.

Yes you can go to File -> Settings -> Editor -> Auto Import -> Java and make the following changes:

1.change Insert imports on paste value to All in drop down option.

2.markAdd unambigious imports on the fly option as checked.(For Window or linux user)

On a Mac, do the same thing in Android Studio -> Preferences

3.You can also use Eclipse shortcut key in Android Studio just go to in Android Studio

File -> Settings -> KeyMap -> Keymaps dropdown Option. Select from them

Thankyou

Just an alternative. Searching google and parsing the results can also be done in a generic way using any HTML Parser such as Jsoup in Java. Following is the link to the mentioned example.

Update: Link no longer works. Please look for any other example. https://www.codeforeach.com/java/example-how-to-search-google-using-java

Had similar problem, was looking for white spaces in a string, solution:

• To search for 1 space:

  var regex = /^.+\s.+$/ ;
  

  example: "user last_name"

• To search for multiple spaces:

  var regex = /^.+\s.+$/g ;
  

  example: "user last name"

For security reasons most browsers do not allow to modify the clipboard (except IE, of course...).

The only way to make a copy-to-clipboard function cross-browser compatible is to use Flash.

check what is using your GPU memory with

sudo fuser -v /dev/nvidia*

Your output will look something like this:

                     USER        PID  ACCESS COMMAND
/dev/nvidia0:        root       1256  F...m  Xorg
                     username   2057  F...m  compiz

                     username   2777  F...m  chrome
                     username   20450 F...m  python
                     username   20699 F...m  python

Then kill the PID that you no longer need on htop or with

sudo kill -9 PID.

In the example above, Pycharm was eating a lot of memory so I killed 20450 and 20699.

For those who still have problems (Cannot pass parameter 2 by reference), define a variable with null value, not just pass null to PDO:

bindValue(':param', $n = null, PDO::PARAM_INT);

Hope this helps.

If you do not want to modify the string (as in the answer by Vincenzo Pii) and want to output the last token as well, you may want to use this approach:

inline std::vector<std::string> splitString( const std::string &s, const std::string &delimiter ){
    std::vector<std::string> ret;
    size_t start = 0;
    size_t end = 0;
    size_t len = 0;
    std::string token;
    do{ end = s.find(delimiter,start); 
        len = end - start;
        token = s.substr(start, len);
        ret.emplace_back( token );
        start += len + delimiter.length();
        std::cout << token << std::endl;
    }while ( end != std::string::npos );
    return ret;
}

Answer : I found this and wants to share it with you.

Sub Copier4()
   Dim x As Integer

   For x = 1 To ActiveWorkbook.Sheets.Count
      'Loop through each of the sheets in the workbook
      'by using x as the sheet index number.
      ActiveWorkbook.Sheets(x).Copy _
         After:=ActiveWorkbook.Sheets(ActiveWorkbook.Sheets.Count)
         'Puts all copies after the last existing sheet.
   Next
End Sub

But the question, can we use it with following code to rename the sheets, if yes, how can we do so?

Sub CreateSheetsFromAList()
Dim MyCell As Range, MyRange As Range
Set MyRange = Sheets("Summary").Range("A10")
Set MyRange = Range(MyRange, MyRange.End(xlDown))
For Each MyCell In MyRange
Sheets.Add After:=Sheets(Sheets.Count) 'creates a new worksheet
Sheets(Sheets.Count).Name = MyCell.Value ' renames the new worksheet
Next MyCell
End Sub

You can setup a default username via ~/.subversion/servers:

[groups]
yourgroupname = svn.example.com

[yourgroupname]
username = yourusername

Please be aware that older versions of svn do not support it (e.g. 1.3.1 [sic!]).

echo GetMAC();

function GetMAC(){
    ob_start();
    system('getmac');
    $Content = ob_get_contents();
    ob_clean();
    return substr($Content, strpos($Content,'\\')-20, 17);
}

Above will basically execute the getmac program and parse its console-output, resulting to MAC-address of the server (and/or where ever PHP is installed and running on).

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

open Developer command prompt as Admin and navigate to

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319

Now use path where is your .exe there

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

You can do this with the standard Linq.ToLookup(). This will create a collection of values for each unique key. Just select the first item in the collection

Persons.ToLookup(p => p.Id).Select(coll => coll.First());

Try this: (For Preview)

<script type="text/javascript">
    function readURL(input) {
        if (input.files && input.files[0]) {
            var reader = new FileReader();

            reader.onload = function (e) {
                $('#blah').attr('src', e.target.result);
            }

            reader.readAsDataURL(input.files[0]);
        }
    }
</script>

<body>
    <form id="form1" runat="server">
        <input type="file" onchange="readURL(this);" />
        <img id="blah" src="#" alt="your image" />
    </form>
</body>

You can use a simple regex (updated version from user viriathus as eregi is deprecated)

if (preg_match('#^http#', $url) === 1) {
    // Starts with http (case sensitive).
}

or if you want a case insensitive search

if (preg_match('#^http#i', $url) === 1) {
    // Starts with http (case insensitive).
}

Regexes allow to perform more complex tasks

if (preg_match('#^https?://#i', $url) === 1) {
    // Starts with http:// or https:// (case insensitive).
}

Performance wise, you don't need to create a new string (unlike with substr) nor parse the whole string if it doesn't start with what you want. You will have a performance penalty though the 1st time you use the regex (you need to create/compile it).

This extension maintains a global per-thread cache of compiled regular expressions (up to 4096). http://www.php.net/manual/en/intro.pcre.php

Put this in C2 and copy down

=IF(ISNA(VLOOKUP(A2,$B$2:$B$65535,1,FALSE)),"not in B","")

Then if the value in A isn't in B the cell in column C will say "not in B".

Yes, you can use Arrays.copyOfRange

It does about the same thing (note there is a copy : you don't change the initial array).

You should use the = operator for string comparison:

Sourcesystem="ABC"

if [ "$Sourcesystem" = "XYZ" ]; then 
    echo "Sourcesystem Matched" 
else
    echo "Sourcesystem is NOT Matched $Sourcesystem"  
fi;

man test says that you use -z to match for empty strings.

There are many answers here already, but some have heavy upvotes and are incorrect.

The .NET Environment.ProcessorCount WILL return incorrect values and can fail critically if your system WMI is configured incorrectly.

If you want a RELIABLE way to count the cores, the only way is Win32 API.

Here is a C++ snippet:

#include <Windows.h>
#include <vector>

int num_physical_cores()
{
    static int num_cores = []
    {
        DWORD bytes = 0;
        GetLogicalProcessorInformation(nullptr, &bytes);
        std::vector<SYSTEM_LOGICAL_PROCESSOR_INFORMATION> coreInfo(bytes / sizeof(SYSTEM_LOGICAL_PROCESSOR_INFORMATION));
        GetLogicalProcessorInformation(coreInfo.data(), &bytes);

        int cores = 0;
        for (auto& info : coreInfo)
        {
            if (info.Relationship == RelationProcessorCore)
                ++cores;
        }
        return cores > 0 ? cores : 1;
    }();
    return num_cores;
}

And since this is a .NET C# Question, here's the ported version:

[StructLayout(LayoutKind.Sequential)]
struct CACHE_DESCRIPTOR
{
    public byte Level;
    public byte Associativity;
    public ushort LineSize;

    var coreInfo = new SYSTEM_LOGICAL_PROCESSOR_INFORMATION[numEntries];

    fixed (SYSTEM_LOGICAL_PROCESSOR_INFORMATION* pCoreInfo = coreInfo)
    {
        GetLogicalProcessorInformation(pCoreInfo, out bufferSize);
        int cores = 0;
        for (int i = 0; i < numEntries; ++i)

                ++cores;
        }
        return cores > 0 ? cores : 1;
    }
}

I'd like to add that for accessibility, I think you should add focus trigger :

i.e. $("#popover").popover({ trigger: "hover focus" });

If you don't remember your password, then run this command in the Shell:

mysqladmin.exe -u root password NewPassword

where 'NewPassword' is your new password.

Not sure if this is correct in any sense but this seems to work for me.

someHeader.h
inline int someVar;

I don't have linking/multiple definition issues and it "just works"... ;- )

It's quite handy for "quick" tests... Try to avoid global vars tho, because every says so... ;- )

It's because you're missing position:relative; on #contentframe

<div id="contentframe" style="position:relative; top: 160px; left: 0px;">

position:absolute; positions itself against the closest ancestor that has a position that is not static. Since the default is static that is what was causing your issue.

You have to sink "output" and "message" separately (the sink function only looks at the first element of type)

Now if you want the input to be logged too, then put it in a script:

script.R

1:5 + 1:3   # prints and gives a warning
stop("foo") # an error

And at the prompt:

con <- file("test.log")
sink(con, append=TRUE)
sink(con, append=TRUE, type="message")

# This will echo all input and not truncate 150+ character lines...
source("script.R", echo=TRUE, max.deparse.length=10000)

# Restore output to console
sink() 
sink(type="message")

# And look at the log...
cat(readLines("test.log"), sep="\n")

There are several methods.

If you want just the consolidated string value returned, this is a good quick and easy approach

DECLARE @combinedString VARCHAR(MAX)
SELECT @combinedString = COALESCE(@combinedString + ', ', '') + stringvalue
FROM jira.customfieldValue
WHERE customfield = 12534
    AND ISSUE = 19602

SELECT @combinedString as StringValue 

Which will return your combined string.

You can also try one of the XML methods e.g.

SELECT DISTINCT Issue, Customfield, StringValues
FROM Jira.customfieldvalue v1
CROSS APPLY ( SELECT StringValues + ',' 
              FROM jira.customfieldvalue v2
              WHERE v2.Customfield = v1.Customfield 
                  AND v2.Issue = v1.issue 
              ORDER BY ID 
                  FOR XML PATH('') )  D ( StringValues )
WHERE customfield = 12534
    AND ISSUE = 19602

For linux users, and to sum up and add to what others have said here, you should know the following:

1. Global variables are not evil. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

The other issue here lies under Code Signing Identity under the Build Settings. Be sure that it contains the Code Signing Identity: "iOS Developer" as opposed to "Don't Code Sign." This will allow you to deploy it to your iOS device. Especially, if you have downloaded a GitHub example or something to this effect.

You'll need to join twice:

SELECT home.*, away.*, g.network, g.date_start 
FROM game AS g
INNER JOIN team AS home
  ON home.importid = g.home
INNER JOIN team AS away
  ON away.importid = g.away
ORDER BY g.date_start DESC 
LIMIT 7

File protocol URIs are like this

file://[HOST]/[PATH]

that's why you often see file URLs like this (3 slashes) file:///c:\path...

So if the host is server01, you want

file://server01/folder/path....

This is according to the wikipedia page on file:// protocols and checks out with .NET's Uri.IsWellFormedUriString method.

If you are passing data to a DOM element from the server, you should set the data on the element:

<a id="foo" data-foo="bar" href="#">foo!</a>

The data can then be accessed using .data() in jQuery:

console.log( $('#foo').data('foo') );
//outputs "bar"

However when you store data on a DOM node in jQuery using data, the variables are stored on the node object. This is to accommodate complex objects and references as storing the data on the node element as an attribute will only accommodate string values.

$('#foo').data('foo', 'baz');

console.log( $('#foo').attr('data-foo') );
//outputs "bar" as the attribute was never changed

console.log( $('#foo').data('foo') );
//outputs "baz" as the value has been updated on the object

Also, the naming convention for data attributes has a bit of a hidden "gotcha":

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('fooBarBaz') );
//outputs "fizz-buzz" as hyphens are automatically camelCase'd

The hyphenated key will still work:

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('foo-bar-baz') );
//still outputs "fizz-buzz"

However the object returned by .data() will not have the hyphenated key set:

$('#bar').data().fooBarBaz; //works
$('#bar').data()['fooBarBaz']; //works
$('#bar').data()['foo-bar-baz']; //does not work

It's for this reason I suggest avoiding the hyphenated key in javascript.

For HTML, keep using the hyphenated form. HTML attributes are supposed to get ASCII-lowercased automatically, so <div data-foobar></div>, <DIV DATA-FOOBAR></DIV>, and <dIv DaTa-FoObAr></DiV> are supposed to be treated as identical, but for the best compatibility the lower case form should be preferred.

The .data() method will also perform some basic auto-casting if the value matches a recognized pattern:

<a id="foo"
    href="#"
    data-str="bar"
    data-bool="true"
    data-num="15"
    data-json='{"fizz":["buzz"]}'>foo!</a>

$('#foo').data('str');  //`"bar"`
$('#foo').data('bool'); //`true`
$('#foo').data('num');  //`15`
$('#foo').data('json'); //`{fizz:['buzz']}`

This auto-casting ability is very convenient for instantiating widgets & plugins:

$('.widget').each(function () {
    $(this).widget($(this).data());
    //-or-
    $(this).widget($(this).data('widget'));
});

If you absolutely must have the original value as a string, then you'll need to use .attr():

<a id="foo" href="#" data-color="ABC123"></a>
<a id="bar" href="#" data-color="654321"></a>

$('#foo').data('color').length; //6
$('#bar').data('color').length; //undefined, length isn't a property of numbers

$('#foo').attr('data-color').length; //6
$('#bar').attr('data-color').length; //6

_{This was a contrived example. For storing color values, I used to use numeric hex notation (i.e. 0xABC123), but it's worth noting that hex was parsed incorrectly in jQuery versions before 1.7.2, and is no longer parsed into a Number as of jQuery 1.8 rc 1.}

jQuery 1.8 rc 1 changed the behavior of auto-casting. Before, any format that was a valid representation of a Number would be cast to Number. Now, values that are numeric are only auto-cast if their representation stays the same. This is best illustrated with an example.

<a id="foo"
    href="#"
    data-int="1000"
    data-decimal="1000.00"
    data-scientific="1e3"
    data-hex="0x03e8">foo!</a>

                              // pre 1.8    post 1.8
$('#foo').data('int');        //    1000        1000
$('#foo').data('decimal');    //    1000   "1000.00"
$('#foo').data('scientific'); //    1000       "1e3"
$('#foo').data('hex');        //    1000     "0x03e8"

If you plan on using alternative numeric syntaxes to access numeric values, be sure to cast the value to a Number first, such as with a unary + operator.

+$('#foo').data('hex'); // 1000

Do aman 2 sendfile. You only need to open the source file on the client and destination file on the server, then call sendfile and the kernel will chop and move the data.

You cannot decrypt this password again but there is another method named "pwdcompare". Here is a example how to use it with SQL syntax:

CREATE TABLE tempdb..h (id_num int, hash varbinary (255))
SET @hash = pwdencrypt('123') -- encryption
INSERT INTO tempdb..h (id_num,hash) VALUES (1,@hash)
SET @hash = pwdencrypt('123')
INSERT INTO tempdb..h (id_num,hash) VALUES (2,@hash)
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 2
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
INSERT INTO tempdb..h (id_num,hash)

SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
DROP TABLE tempdb..h

1. the best way to delete a record is to find it firstly (if exist in data base in the same time you want to delete it)
2. watch this code

UPDATE 7/3/2014: As of now, jquery-latest.js is no longer being updated. From the jQuery blog:

We know that http://code.jquery.com/jquery-latest.js is abused because of the CDN statistics showing it’s the most popular file. That wouldn’t be the case if it was only being used by developers to make a local copy.

We have decided to stop updating this file, as well as the minified copy, keeping both files at version 1.11.1 forever.

The Google CDN team has joined us in this effort to prevent inadvertent web breakage and no longer updates the file at http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js. That file will stay locked at version 1.11.1 as well.

The following, now moot, answer is preserved here for historical reasons.

Don't do this. Seriously, don't.

Linking to major versions of jQuery does work, but it's a bad idea -- whole new features get added and deprecated with each decimal update. If you update jQuery automatically without testing your code COMPLETELY, you risk an unexpected surprise if the API for some critical method has changed.

Here's what you should be doing: write your code using the latest version of jQuery. Test it, debug it, publish it when it's ready for production.

Then, when a new version of jQuery rolls out, ask yourself: Do I need this new version in my code? For instance, is there some critical browser compatibility that didn't exist before, or will it speed up my code in most browsers?

If the answer is "no", don't bother updating your code to the latest jQuery version. Doing so might even add NEW errors to your code which didn't exist before. No responsible developer would automatically include new code from another site without testing it thoroughly.

There's simply no good reason to ALWAYS be using the latest version of jQuery. The old versions are still available on the CDNs, and if they work for your purposes, then why bother replacing them?

A secondary, but possibly more important, issue is caching. Many people link to jQuery on a CDN because many other sites do, and your users have a good chance of having that version already cached.

The problem is, caching only works if you provide a full version number. If you provide a partial version number, far-future caching doesn't happen -- because if it did, some users would get different minor versions of jQuery from the same URL. (Say that the link to 1.7 points to 1.7.1 one day and 1.7.2 the next day. How will the browser make sure it's getting the latest version today? Answer: no caching.)

In fact here's a breakdown of several options and their expiration settings...

http://code.jquery.com/jquery-latest.min.js (no cache)

http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js (1 year)

So, by linking to jQuery this way, you're actually eliminating one of the major reasons to use a CDN in the first place.

http://code.jquery.com/jquery-latest.min.js may not always give you the version you expect, either. As of this writing, it links to the latest version of jQuery 1.x, even though jQuery 2.x has been released as well. This is because jQuery 1.x is compatible with older browsers including IE 6/7/8, and jQuery 2.x is not. If you want the latest version of jQuery 2.x, then (for now) you need to specify that explicitly.

The two versions have the same API, so there is no perceptual difference for compatible browsers. However, jQuery 1.x is a larger download than 2.x.

%s will get all the values until it gets NULL i.e. '\0'.

char str1[] = "This is the end\0";
printf("%s",str1);

will give

This is the end

char str2[] = "this is\0 the end\0";
printf("%s",str2);

will give

this is

You can use this:

$array = array("one" => "apple", "two" => "orange", "three" => "pear");
end($array); 
echo key($array);

Another Solution is to create a function and use it:

function endKey($array){
end($array);
return key($array);
}

$array = array("one" => "apple", "two" => "orange", "three" => "pear");
echo endKey($array);

It is also possible to use Spring Data JDBC repository, which is a community project built on top of Spring Data Commons to access to databases with raw SQL, without using JPA.

It is less powerful than Spring Data JPA, but if you want lightweight solution for simple projects without using a an ORM like Hibernate, that a solution worth to try.

You can be an absolute madman and alias vim to vim -p by adding in your .bashrc:

alias vim="vim -p"

This will result in opening multiple files from the shell in tabs, without having to invoke :tab ball from within vim afterwards.

Here is an example to fully programmatically:

• init a Spinner.
• fill it with data via a String List.
• resize the Spinner and add it to my View.
• format the Spinner font (font size, colour, padding).
• clear the Spinner.
• add new values to the Spinner.
• redraw the Spinner.

I am using the following class vars:

Spinner varSpinner;
List<String> varSpinnerData;

float varScaleX;
float varScaleY;    

A - Init and render the Spinner (varRoot is a pointer to my main Activity):

public void renderSpinner() {


    List<String> myArraySpinner = new ArrayList<String>();

    myArraySpinner.add("red");
    myArraySpinner.add("green");
    myArraySpinner.add("blue");     

    varSpinnerData = myArraySpinner;

    Spinner mySpinner = new Spinner(varRoot);               

    varSpinner = mySpinner;

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(varRoot, android.R.layout.simple_spinner_item, myArraySpinner);
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down vieww
    mySpinner.setAdapter(spinnerArrayAdapter);

B - Resize and Add the Spinner to my View:

    FrameLayout.LayoutParams myParamsLayout = new FrameLayout.LayoutParams(
            FrameLayout.LayoutParams.MATCH_PARENT, 
            FrameLayout.LayoutParams.WRAP_CONTENT);
    myParamsLayout.gravity = Gravity.NO_GRAVITY;             

    myParamsLayout.leftMargin = (int) (100 * varScaleX);
    myParamsLayout.topMargin = (int) (350 * varScaleY);             
    myParamsLayout.width = (int) (300 * varScaleX);;
    myParamsLayout.height = (int) (60 * varScaleY);;


    varLayoutECommerce_Dialogue.addView(mySpinner, myParamsLayout);

C - Make the Click handler and use this to set the font.

    mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int myPosition, long myID) {

            Log.i("renderSpinner -> ", "onItemSelected: " + myPosition + "/" + myID);

            ((TextView) parentView.getChildAt(0)).setTextColor(Color.GREEN);
            ((TextView) parentView.getChildAt(0)).setTextSize(TypedValue.COMPLEX_UNIT_PX, (int) (varScaleY * 22.0f) );
            ((TextView) parentView.getChildAt(0)).setPadding(1,1,1,1);


        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) {
            // your code here
        }

    });

}   

D - Update the Spinner with new data:

private void updateInitSpinners(){

     String mySelected = varSpinner.getSelectedItem().toString();
     Log.i("TPRenderECommerce_Dialogue -> ", "updateInitSpinners -> mySelected: " + mySelected);


     varSpinnerData.clear();

     varSpinnerData.add("Hello World");
     varSpinnerData.add("Hello World 2");

     ((BaseAdapter) varSpinner.getAdapter()).notifyDataSetChanged();
     varSpinner.invalidate();
     varSpinner.setSelection(1);

}

}

What I have not been able to solve in the updateInitSpinners, is to do varSpinner.setSelection(0); and have the custom font settings activated automatically.

UPDATE:

This "ugly" solution solves the varSpinner.setSelection(0); issue, but I am not very happy with it:

private void updateInitSpinners(){

    String mySelected = varSpinner.getSelectedItem().toString();
    Log.i("TPRenderECommerce_Dialogue -> ", "updateInitSpinners -> mySelected: " + mySelected);


    varSpinnerData.clear();

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(varRoot, android.R.layout.simple_spinner_item, varSpinnerData);
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    varSpinner.setAdapter(spinnerArrayAdapter);  


    varSpinnerData.add("Hello World");
    varSpinnerData.add("Hello World 2");

    ((BaseAdapter) varSpinner.getAdapter()).notifyDataSetChanged();
    varSpinner.invalidate();
    varSpinner.setSelection(0);

}

}

Hope this helps......

To fix OutOfMemory you should do something like that please try this code

public Bitmap loadBitmap(String URL, BitmapFactory.Options options) {
                Bitmap bitmap = null;
                InputStream in = null;
                options.inSampleSize=4;
                try {
                    in = OpenHttpConnection(URL);
                    Log.e("In====>", in+"");
                    bitmap = BitmapFactory.decodeStream(in, null, options);
                    Log.e("URL====>", bitmap+"");

                    in.close();
                } catch (IOException e1) {
                }
                return bitmap;
            }

and

try {
                    BitmapFactory.Options bmOptions;
                    bmOptions = new BitmapFactory.Options();
                    bmOptions.inSampleSize = 1;
                    if(studentImage != null){
                        galleryThumbnail= loadBitmap(IMAGE_URL+studentImage, bmOptions);    
                    }

                    galleryThumbnail=getResizedBitmap(galleryThumbnail, imgEditStudentPhoto.getHeight(), imgEditStudentPhoto.getWidth());
                    Log.e("Image_Url==>",IMAGE_URL+studentImage+"");

                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

I have used a different approach to search for a file using stack.. keeping in mind that there could be folders inside a folder. Though its not faster than windows search(and I was not expecting that though) but it definitely gives out correct result. Please modify the code as you wish to. This code was originally made to extract the file path of certain file extension :). Feel free to optimize.

Look at the dba_blockers, dba_waiters and dba_locks for locking. The names should be self explanatory.

You could create a job that runs, say, once a minute and logged the values in the dba_blockers and the current active sql_id for that session. (via v$session and v$sqlstats).

You may also want to look in v$sql_monitor. This will be default log all SQL that takes longer than 5 seconds. It is also visible on the "SQL Monitoring" page in Enterprise Manager.

The sqlite team published an article explaining when to use sqlite that is great read. Basically, you want to avoid using sqlite when you have a lot of write concurrency or need to scale to terabytes of data. In many other cases, sqlite is a surprisingly good alternative to a "traditional" database such as MySQL.

I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany to look at each item in each group.

I think you just want:

List<ResultLine> result = Lines
    .GroupBy(l => l.ProductCode)
    .Select(cl => new ResultLine
            {
                ProductName = cl.First().Name,
                Quantity = cl.Count().ToString(),
                Price = cl.Sum(c => c.Price).ToString(),
            }).ToList();

The use of First() here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.

I'd also suggest that you should change the Quantity and Price properties to be int and decimal types respectively - why use a string property for data which is clearly not textual?

If you're coming to Python from a language in the C/Java/etc. family, it may help you to stop thinking about a as a "variable", and start thinking of it as a "name".

a, b, and c aren't different variables with equal values; they're different names for the same identical value. Variables have types, identities, addresses, and all kinds of stuff like that.

Names don't have any of that. Values do, of course, and you can have lots of names for the same value.

If you give Notorious B.I.G. a hot dog,* Biggie Smalls and Chris Wallace have a hot dog. If you change the first element of a to 1, the first elements of b and c are 1.

If you want to know if two names are naming the same object, use the is operator:

>>> a=b=c=[0,3,5]
>>> a is b
True

You then ask:

what is different from this?

d=e=f=3
e=4
print('f:',f)
print('e:',e)

Here, you're rebinding the name e to the value 4. That doesn't affect the names d and f in any way.

In your previous version, you were assigning to a[0], not to a. So, from the point of view of a[0], you're rebinding a[0], but from the point of view of a, you're changing it in-place.

You can use the id function, which gives you some unique number representing the identity of an object, to see exactly which object is which even when is can't help:

>>> a=b=c=[0,3,5]
>>> id(a)
4473392520
>>> id(b)
4473392520
>>> id(a[0])
4297261120
>>> id(b[0])
4297261120

>>> a[0] = 1
>>> id(a)
4473392520
>>> id(b)
4473392520
>>> id(a[0])
4297261216
>>> id(b[0])
4297261216

Notice that a[0] has changed from 4297261120 to 4297261216—it's now a name for a different value. And b[0] is also now a name for that same new value. That's because a and b are still naming the same object.

Under the covers, a[0]=1 is actually calling a method on the list object. (It's equivalent to a.__setitem__(0, 1).) So, it's not really rebinding anything at all. It's like calling my_object.set_something(1). Sure, likely the object is rebinding an instance attribute in order to implement this method, but that's not what's important; what's important is that you're not assigning anything, you're just mutating the object. And it's the same with a[0]=1.

user570826 asked:

What if we have, a = b = c = 10

That's exactly the same situation as a = b = c = [1, 2, 3]: you have three names for the same value.

But in this case, the value is an int, and ints are immutable. In either case, you can rebind a to a different value (e.g., a = "Now I'm a string!"), but the won't affect the original value, which b and c will still be names for. The difference is that with a list, you can change the value [1, 2, 3] into [1, 2, 3, 4] by doing, e.g., a.append(4); since that's actually changing the value that b and c are names for, b will now b [1, 2, 3, 4]. There's no way to change the value 10 into anything else. 10 is 10 forever, just like Claudia the vampire is 5 forever (at least until she's replaced by Kirsten Dunst).

* Warning: Do not give Notorious B.I.G. a hot dog. Gangsta rap zombies should never be fed after midnight.

Future and Promise are proxy object for unknown result

Promise completes a Future

• Future - read/consumer of unknown result

• Promise - write/producer of unknown result.

//Future has a reference to Promise
Future -> Promise

As a producer I promise something and responsible for it

As a consumer who retrieved a promise I expect to have a result in future

As for Java CompletableFutures it is a Promise because you can set the result and also it implements Future

Here is my solution in Enterprise 1.11 (should work in CE 1.6):

    $collection->addFieldToFilter('max_item_count',
                    array(
                        array('gteq' => 10),
                        array('null' => true),
                    )
            )
            ->addFieldToFilter('max_item_price',
                    array(
                        array('gteq' => 9.99),
                        array('null' => true),
                    )
            )
            ->addFieldToFilter('max_item_weight',
                    array(
                        array('gteq' => 1.5),
                        array('null' => true),
                    )
            );

Which results in this SQL:

    SELECT `main_table`.*
    FROM `shipping_method_entity` AS `main_table`
    WHERE (((max_item_count >= 10) OR (max_item_count IS NULL)))
      AND (((max_item_price >= 9.99) OR (max_item_price IS NULL)))
      AND (((max_item_weight >= 1.5) OR (max_item_weight IS NULL)))

I don't know if Boost has anything that would help.

My preferred pattern is simple: take a template argument which is equal to value_type, either const qualified or not. If necessary, also a node type. Then, well, everything kind of falls into place.

Just remember to parameterize (template-ize) everything that needs to be, including the copy constructor and operator==. For the most part, the semantics of const will create correct behavior.

template< class ValueType, class NodeType >
struct my_iterator
 : std::iterator< std::bidirectional_iterator_tag, T > {
    ValueType &operator*() { return cur->payload; }

    template< class VT2, class NT2 >
    friend bool operator==
        ( my_iterator const &lhs, my_iterator< VT2, NT2 > const &rhs );

    // etc.

private:
    NodeType *cur;

    friend class my_container;
    my_iterator( NodeType * ); // private constructor for begin, end
};

typedef my_iterator< T, my_node< T > > iterator;
typedef my_iterator< T const, my_node< T > const > const_iterator;

You can simply write:

val mutableList = mutableListOf<Kolory>()

This is the most idiomatic way.

Alternative ways are

val mutableList : MutableList<Kolory> = arrayListOf()

or

val mutableList : MutableList<Kolory> = ArrayList()

This is exploiting the fact that java types like ArrayList are implicitly implementing the type MutableList via a compiler trick.

When working on a supercomputer, I received this error when I ran:

To resolve the error, I simply needed to reload the module in the screen terminal:

I am assuming you want to pass the database name as a parameter and not just run:

SELECT  *
FROM    DBName.sys.tables
WHERE   Name LIKE '%XXX%'

If so, you could use dynamic SQL to add the dbname to the query:

DECLARE @DBName NVARCHAR(200) = 'YourDBName',
        @TableName NVARCHAR(200) = 'SomeString';

IF NOT EXISTS (SELECT 1 FROM master.sys.databases WHERE Name = @DBName)
    BEGIN
        PRINT 'DATABASE NOT FOUND';
        RETURN;
    END;

DECLARE @SQL NVARCHAR(MAX) = '  SELECT  Name
                                FROM    ' + QUOTENAME(@DBName) + '.sys.tables
                                WHERE   Name LIKE ''%'' + @Table + ''%''';

EXECUTE SP_EXECUTESQL @SQL, N'@Table NVARCHAR(200)', @TableName;

document.getElementById('id').style = 'left: 55%; z-index: 999; overflow: hidden; width: 0px; height: 0px; opacity: 0; display: none;';

works for me

Assuming you're doing more than just adding this one class (eg, you've got asynchronous requests and so on going on as well), I'd recommend a library like Prototype or jQuery.

This will make just about everything you'll need to do (including this) very simple.

So let's say you've got jQuery on your page now, you could use code like this to add a class name to an element (on load, in this case):

$(document).ready( function() {
  $('#div1').addClass( 'some_other_class' );
} );

Check out the jQuery API browser for other stuff.

psql below 9.2 does not accept this URL-like syntax for options.

The use of SSL can be driven by the sslmode=value option on the command line or the PGSSLMODE environment variable, but the default being prefer, SSL connections will be tried first automatically without specifying anything.

Example with a conninfo string (updated for psql 8.4)

psql "sslmode=require host=localhost dbname=test"

Read the manual page for more options.

Here is the best example of Cross Join and Inner Join.

Consider the following tables

TABLE : Teacher

x------------------------x
| TchrId   | TeacherName | 
x----------|-------------x
|    T1    |    Mary     |
|    T2    |    Jim      |
x------------------------x

TABLE : Student

x--------------------------------------x
|  StudId  |    TchrId   | StudentName | 
x----------|-------------|-------------x            
|    S1    |     T1      |    Vineeth  |
|    S2    |     T1      |    Unni     |
x--------------------------------------x

1. INNER JOIN

Inner join selects the rows that satisfies both the table.

Consider we need to find the teachers who are class teachers and their corresponding students. In that condition, we need to apply JOIN or INNER JOIN and will

Query

SELECT T.TchrId,T.TeacherName,S.StudentName 
FROM #Teacher T
INNER JOIN #Student S ON T.TchrId = S.TchrId

• SQL FIDDLE

Result

x--------------------------------------x
|  TchrId  | TeacherName | StudentName | 
x----------|-------------|-------------x            
|    T1    |     Mary    |    Vineeth  |
|    T1    |     Mary    |    Unni     |

2. CROSS JOIN

Cross join selects the all the rows from the first table and all the rows from second table and shows as Cartesian product ie, with all possibilities

Consider we need to find all the teachers in the school and students irrespective of class teachers, we need to apply CROSS JOIN.

Query

SELECT T.TchrId,T.TeacherName,S.StudentName 
FROM #Teacher T
CROSS JOIN #Student S

you can get loccalhost page by writing localhost/xampp or by writing http://127.0.0.1 you will get the local host page. After starting the apache serve that can be from wamp, xamp or lamp.

I had the same error "google is not defined" while using Gmap3. The problem was that I was including 'gmap3' before including 'google', so I reversed the order:

<script src="https://maps.googleapis.com/maps/api/js?sensor=false" type="text/javascript"></script>
<script src="/assets/gmap3.js?body=1" type="text/javascript"></script>

Every distribution has a default shell. Bash is the default on the majority of the systems. If you happen to work on a system that has a different default shell, then the scripts might not work as intended if they are written specific for Bash.

Bash has evolved over the years taking code from ksh and sh.

Adding #!/bin/bash as the first line of your script, tells the OS to invoke the specified shell to execute the commands that follow in the script.

#! is often referred to as a "hash-bang", "she-bang" or "sha-bang".

Did you override the run() method? If you overrided __init__, did you make sure to call the base threading.Thread.__init__()?

After starting the two threads, does the main thread continue to do work indefinitely/block/join on the child threads so that main thread execution does not end before the child threads complete their tasks?

And finally, are you getting any unhandled exceptions?

Instead of using button . you can use Text in react native and then make in touchable

<TouchableOpacity onPress={this._onPressButton}> 
   <Text style = {'your custome style'}>
       button name
   </Text>
</TouchableOpacity >

just enter the following command on command prompt after launching the app:

adb shell dumpsys window windows | find "mCurrentFocus"

if executing the command on linux terminal replace find by grep

This will change your current working directory to so that opening relative paths will work:

import os
os.chdir("/home/udi/foo")

However, you asked how to change into whatever directory your Python script is located, even if you don't know what directory that will be when you're writing your script. To do this, you can use the os.path functions:

import os

abspath = os.path.abspath(__file__)
dname = os.path.dirname(abspath)
os.chdir(dname)

This takes the filename of your script, converts it to an absolute path, then extracts the directory of that path, then changes into that directory.

(Explanation in more details can be found in an archived Microsoft KB article.)

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

In Java Array Sizes are always of Fixed Length But there is way in which you can Dynamically increase the Size of the Array at Runtime Itself

This is the most "used" as well as preferred way to do it-

    int temp[]=new int[stck.length+1];
    for(int i=0;i<stck.length;i++)temp[i]=stck[i];
    stck=temp;

In the above code we are initializing a new temp[] array, and further using a for loop to initialize the contents of the temp with the contents of the original array ie. stck[]. And then again copying it back to the original one, giving us a new array of new SIZE.

No doubt it generates a CPU Overhead due to reinitializing an array using for loop repeatedly. But you can still use and implement it in your code. For the best practice use "Linked List" instead of Array, if you want the data to be stored dynamically in the memory, of variable length.

Here's a Real-Time Example based on Dynamic Stacks to INCREASE ARRAY SIZE at Run-Time

File-name: DStack.java

public class DStack {
private int stck[];
int tos;

void Init_Stck(int size) {
    stck=new int[size];
    tos=-1;
}
int Change_Stck(int size){
    return stck[size];
}

public void push(int item){
    if(tos==stck.length-1){
        int temp[]=new int[stck.length+1];
        for(int i=0;i<stck.length;i++)temp[i]=stck[i];
        stck=temp;
        stck[++tos]=item;
    }
    else
        stck[++tos]=item;
}
public int pop(){
    if(tos<0){
        System.out.println("Stack Underflow");
        return 0;
    }
    else return stck[tos--];
}

public void display(){
    for(int x=0;x<stck.length;x++){
        System.out.print(stck[x]+" ");
    }
    System.out.println();
}

}

File-name: Exec.java
(with the main class)

import java.util.*;
public class Exec {

private static Scanner in;

public static void main(String[] args) {
    in = new Scanner(System.in);
    int option,item,i=1;
    DStack obj=new DStack();
    obj.Init_Stck(1);
    do{
        System.out.println();
        System.out.println("--MENU--");
        System.out.println("1. Push a Value in The Stack");
        System.out.println("2. Pop a Value from the Stack");
        System.out.println("3. Display Stack");
        System.out.println("4. Exit");
        option=in.nextInt();
        switch(option){
        case 1:
            System.out.println("Enter the Value to be Pushed");
            item=in.nextInt();
            obj.push(item);
            break;
        case 2:
            System.out.println("Popped Item: "+obj.pop());
            obj.Change_Stck(obj.tos);
            break;
        case 3:
            System.out.println("Displaying...");
            obj.display();
            break;
        case 4:
            System.out.println("Exiting...");
            i=0;
            break;
        default:
            System.out.println("Enter a Valid Value");

        }
    }while(i==1);

}

}

Hope this solves your query.

You can create the ordered dict from old dict in one line:

from collections import OrderedDict
ordered_dict = OrderedDict(sorted(ship.items())

The default sorting key is by dictionary key, so the new ordered_dict is sorted by old dict's keys.

As Thomas says, the cin ignore is a good way. To always wait for user to press enter (even if exit is used), register a function atexit:

#include <iostream>

void pause()
{   ::std::cout<<"\nPress ENTER to exit.";
    ::std::cin.sync();
    if(::std::cin.get()!='\n')
        ::std::cin.ignore(0xFFFFFFFF,'\n');
}

int main()
{
    atexit(pause);

    // whatever

    return 0;
}

Open Notepad.

Type the following lines into it (obviously replace the folders with your ones)

@echo off
rem you could also remove the line above, because it might help you to see what happens

rem /i option is needed to avoid the batch file asking you whether destination folder is a file or a folder
rem /e option is needed to copy also all folders and subfolders
xcopy "c:\New Folder" "c:\Copy of New Folder" /i /e

Save the file as backup.bat (not .txt)

Double click on the file to run it. It will backup the folder and all its contents files/subfolders.

Now if you want the batch file to be run everytime you login in Windows, you should place it in Windows Startup menu. You find it under: Start > All Program > Startup To place the batch file in there either drag it into the Startup menu or RIGH click on the Windows START button and select Explore, go in Programs > Startup, and copy the batch file into there.

To run the batch file everytime the folder is updated you need an application, it can not be done with just a batch file.

Notes, Cautions and Caveats

Your initial solution did not show any obvious santisation of the values before passing them into the Database. This is how SQL Injection attacks (or even un-intentional errors being passed through SQL) occur. Don't do it!

Your database does not seem to have a Primary Key. Whilst these are not, technically, necessary in all usage, they are a good practice, and make for a much more reliable way of referring to a specific row in a table, whether for adding related tables, or for making changes within that table.

You need to check every action, at every stage, for errors. Most PHP functions are nice enough to have a response they will return under an error condition. It is your job to check for those conditions as you go - never assume that PHP will do what you expect, how you expect, and in the order you expect. This is how accident happen...

My provided code above contains alot of points where, if an error has occured, a message will be returned. Try it, see if any error messages are reported, look at the Error Message, and, if applicable, the Error Code returned and do some research.

Good luck.

SOLVED
After banging my head on the wall for a couple days with this issue, it was looking like the problem had something to do with the content type negotiation between the client and server. I dug deeper into that using Fiddler to check the request details coming from the client app, here's a screenshot of the raw request as captured by fiddler:

What's obviously missing there is the Content-Type header, even though I was setting it as seen in the code sample in my original post. I thought it was strange that the Content-Type never came through even though I was setting it, so I had another look at my other (working) code calling a different Web API service, the only difference was that I happened to be setting the req.ContentType property prior to writing to the request body in that case. I made that change to this new code and that did it, the Content-Type was now showing up and I got the expected success response from the web service. The new code from my .NET client now looks like this:

req.Method = "POST"
req.ContentType = "application/json"
lstrPagingJSON = JsonSerializer(Of Paging)(lPaging)
bytData = Encoding.UTF8.GetBytes(lstrPagingJSON)
req.ContentLength = bytData.Length
reqStream = req.GetRequestStream()
reqStream.Write(bytData, 0, bytData.Length)
reqStream.Close()
'// Content-Type was being set here, causing the problem
'req.ContentType = "application/json"

That's all it was, the ContentType property just needed to be set prior to writing to the request body

I believe this behavior is because once content is written to the body it is streamed to the service endpoint being called, any other attributes pertaining to the request need to be set prior to that. Please correct me if I'm wrong or if this needs more detail.

You could also insert the results (or top 10 results) into a temp table and get the columns from the temp table (as long as the column names are all different).

SELECT TOP 10 *
INTO #TempTable
FROM <DataSource>

Then use:

EXEC tempdb.dbo.sp_help N'#TempTable';

or

SELECT * 
FROM tempdb.sys.columns 
WHERE [object_id] = OBJECT_ID(N'tempdb..#TempTable');

Extrapolated from Aaron's answer here.

In Java 8, the syntax for this simplifies greatly and can be used to accomplish this transformation succinctly.

Do note, you will need to change your field from a concrete implementation to the List interface for this to work smoothly.

public class Wetland {
    private String name;
    private List<String> species;
    public Wetland(String name, String[] speciesArr) {
        this.name = name;
        species = Arrays.stream(speciesArr)
                        .collect(Collectors.toList());
    }
}

I try to explain it more understandably than the referred PostgreSQL documentation.

Neither TIMESTAMP variants store a time zone (or an offset), despite what the names suggest. The difference is in the interpretation of the stored data (and in the intended application), not in the storage format itself:

• TIMESTAMP WITHOUT TIME ZONE stores local date-time (aka. wall calendar date and wall clock time). Its time zone is unspecified as far as PostgreSQL can tell (though your application may knows what it is). Hence, PostgreSQL does no time zone related conversion on input or output. If the value was entered into the database as '2011-07-01 06:30:30', then no mater in what time zone you display it later, it will still say year 2011, month 07, day 01, 06 hours, 30 minutes, and 30 seconds (in some format). Also, any offset or time zone you specify in the input is ignored by PostgreSQL, so '2011-07-01 06:30:30+00' and '2011-07-01 06:30:30+05' are the same as just '2011-07-01 06:30:30'. For Java developers: it's analogous to java.time.LocalDateTime.

• TIMESTAMP WITH TIME ZONE stores a point on the UTC time line. How it looks (how many hours, minutes, etc.) depends on your time zone, but it always refers to the same "physical" instant (like the moment of an actual physical event). The input is internally converted to UTC, and that's how it's stored. For that, the offset of the input must be known, so when the input contains no explicit offset or time zone (like '2011-07-01 06:30:30') it's assumed to be in the current time zone of the PostgreSQL session, otherwise the explicitly specified offset or time zone is used (as in '2011-07-01 06:30:30+05'). The output is displayed converted to the current time zone of the PostgreSQL session. For Java developers: It's analogous to java.time.Instant (with lower resolution though), but with JDBC and JPA 2.2 you are supposed to map it to java.time.OffsetDateTime (or to java.util.Date or java.sql.Timestamp of course).

Some say that both TIMESTAMP variations store UTC date-time. Kind of, but it's confusing to put it that way in my opinion. TIMESTAMP WITHOUT TIME ZONE is stored like a TIMESTAMP WITH TIME ZONE, which rendered with UTC time zone happens to give the same year, month, day, hours, minutes, seconds, and microseconds as they are in the local date-time. But it's not meant to represent the point on the time line that the UTC interpretation says, it's just the way the local date-time fields are encoded. (It's some cluster of dots on the time line, as the real time zone is not UTC; we don't know what it is.)

find ./ -cTime -1 -type f

OR

find ./ -cmin -60 -type f

You take the string and pass it to list()

s = "mystring"
l = list(s)
print l

You can use the JFileChooser class, check this example.

If your input is a child element of the label and you have more than one labels, you can combine @Mike's trick with Flexbox + order.

label.switchLabel {
  display: flex;
  justify-content: space-between;
  width: 150px;
}
.switchLabel .left   { order: 1; }
.switchLabel .switch { order: 2; }
.switchLabel .right  { order: 3; }

/* sibling selector ~ */
.switchLabel .switch:not(:checked) ~ span.left { color: lightblue }
.switchLabel .switch:checked ~ span.right { color: lightblue }



/* style the switch */

:root {
  --radio-size: 14px;
}

.switchLabel input.switch  {
  width: var(--radio-size);
  height: var(--radio-size);
  border-radius: 50%;
  border: 1px solid #999999;
  box-sizing: border-box;
  outline: none;
  -webkit-appearance: inherit;
  -moz-appearance: inherit;
  appearance: inherit;
  
  box-shadow: calc(var(--radio-size) / 2) 0 0 0 gray, calc(var(--radio-size) / 4) 0 0 0 gray;
  margin: 0 calc(5px + var(--radio-size) / 2) 0 5px;
}

.switchLabel input.switch:checked {
  box-shadow: calc(-1 * var(--radio-size) / 2) 0 0 0 gray, calc(-1 * var(--radio-size) / 4) 0 0 0 gray;
  margin: 0 5px 0 calc(5px + var(--radio-size) / 2);
}

<label class="switchLabel">
  <input type="checkbox" class="switch" />
  <span class="left">Left</span>
  <span class="right">Right</span>
</label>

<label class="switchLabel">
  <input type="checkbox" class="switch"/>
  <span class="left">Left</span>
  <span class="right">Right</span>
</label>

label.switchLabel {
  display: flex;
  justify-content: space-between;
  width: 150px;
}
.switchLabel .left   { order: 1; }
.switchLabel .switch { order: 2; }
.switchLabel .right  { order: 3; }

/* sibling selector ~ */
.switchLabel .switch:not(:checked) ~ span.left { color: lightblue }
.switchLabel .switch:checked ~ span.right { color: lightblue }

See it on JSFiddle.

note: Sibling selector only works within the same parent. To work around this, you can make the input hidden at top-level using @Nathan Blair hack.

You simply don't call the function.

>>>def x():
>>>    print(20)
>>>y = x
>>>y()
20

The brackets tell python that you are calling the function, so when you put them there, it calls the function and assigns y the value returned by x (which in this case is None).

You can consider using a UI confirmation.

With yesnopopup.bat

@echo off

for /f "tokens=* delims=" %%# in ('yesnopopup.bat') do (
    set "result=%%#"
)

if /i result==no (
    echo user rejected the script
    exit /b 1
) 

echo continue

rem --- other commands --

the user will see the following and depending on the choice the script will continue:

with absolutely the same script you can use also iexpYNbutton.bat which will produce similar popup.

With buttons.bat you can try the following script:

@echo off

for /f "tokens=* delims=" %%# in ('buttons.bat "Yep!" "Nope!" ') do (
    set "result=%%#"
)

if /i result==2 (
    echo user rejected the script
    exit /b 1
) 

echo continue

rem --- other commands --

and the user will see:

You can try something like this

stages {
        stage('Build') {
            environment { 
                    AOEU= sh (returnStdout: true, script: 'echo aoeu').trim()
                }
            steps {
                sh 'env'
                sh 'echo $AOEU'
            }
        }
    }

Note that escaping everything is a bad idea. Sed needs many characters to be escaped to get their special meaning. For example, if you escape a digit in the replacement string, it will turn in to a backreference.

As Ben Blank said, there are only three characters that need to be escaped in the replacement string (escapes themselves, forward slash for end of statement and & for replace all):

ESCAPED_REPLACE=$(printf '%s\n' "$REPLACE" | sed -e 's/[\/&]/\\&/g')
# Now you can use ESCAPED_REPLACE in the original sed statement
sed "s/KEYWORD/$ESCAPED_REPLACE/g"

If you ever need to escape the KEYWORD string, the following is the one you need:

sed -e 's/[]\/$*.^[]/\\&/g'

And can be used by:

KEYWORD="The Keyword You Need";
ESCAPED_KEYWORD=$(printf '%s\n' "$KEYWORD" | sed -e 's/[]\/$*.^[]/\\&/g');

# Now you can use it inside the original sed statement to replace text
sed "s/$ESCAPED_KEYWORD/$ESCAPED_REPLACE/g"

Remember, if you use a character other than / as delimiter, you need replace the slash in the expressions above wih the character you are using. See PeterJCLaw's comment for explanation.

Edited: Due to some corner cases previously not accounted for, the commands above have changed several times. Check the edit history for details.

I ran into the same issue, here's my post:

Android Studio - Gradle build failing - Java Heap Space

exec summary: Windows looks for the gradle.properties file here:

C:\Users\.gradle\gradle.properties

So create that file, and add a line like this:

org.gradle.jvmargs=-XX\:MaxHeapSize\=256m -Xmx256m

as per @Faiz Siddiqui post

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

Try this:

UPDATE test
SET
   field = 1
WHERE id = 123 and condition

In my case the element that generated the Exception was a button belonging to a form. I replaced

WebElement btnLogin = driver.findElement(By.cssSelector("button"));
btnLogin.click();

with

btnLogin.submit();

My environment was chromedriver windows 10

Now there is the pandas_profiling package, which is a more complete alternative to df.describe().

If your pandas dataframe is df, the below will return a complete analysis including some warnings about missing values, skewness, etc. It presents histograms and correlation plots as well.

import pandas_profiling
pandas_profiling.ProfileReport(df)

See the example notebook detailing the usage.

You can use Sass' transparentize.

I found it to be the most useful and plain to use.

transparentize(rgba(0, 0, 0, 0.5), 0.1) => rgba(0, 0, 0, 0.4)
transparentize(rgba(0, 0, 0, 0.8), 0.2) => rgba(0, 0, 0, 0.6) 

See more: #transparentize($color, $amount) ? Sass::Script::Value::Color

The amount of memory allocated for the Java process is pretty much on-par with what I would expect. I've had similar problems running Java on embedded/memory limited systems. Running any application with arbitrary VM limits or on systems that don't have adequate amounts of swap tend to break. It seems to be the nature of many modern apps that aren't design for use on resource-limited systems.

You have a few more options you can try and limit your JVM's memory footprint. This might reduce the virtual memory footprint:

-XX:ReservedCodeCacheSize=32m Reserved code cache size (in bytes) - maximum code cache size. [Solaris 64-bit, amd64, and -server x86: 48m; in 1.5.0_06 and earlier, Solaris 64-bit and and64: 1024m.]

-XX:MaxPermSize=64m Size of the Permanent Generation. [5.0 and newer: 64 bit VMs are scaled 30% larger; 1.4 amd64: 96m; 1.3.1 -client: 32m.]

Also, you also should set your -Xmx (max heap size) to a value as close as possible to the actual peak memory usage of your application. I believe the default behavior of the JVM is still to double the heap size each time it expands it up to the max. If you start with 32M heap and your app peaked to 65M, then the heap would end up growing 32M -> 64M -> 128M.

You might also try this to make the VM less aggressive about growing the heap:

-XX:MinHeapFreeRatio=40 Minimum percentage of heap free after GC to avoid expansion.

Also, from what I recall from experimenting with this a few years ago, the number of native libraries loaded had a huge impact on the minimum footprint. Loading java.net.Socket added more than 15M if I recall correctly (and I probably don't).

Your first example which uses Enumerable.Repeat:

private string Tabs(uint numTabs)
{
    IEnumerable<string> tabs = Enumerable.Repeat(
                                 "\t", (int) numTabs);
    return (numTabs > 0) ? 
            tabs.Aggregate((sum, next) => sum + next) : ""; 
} 

can be rewritten more compactly with String.Concat:

private string Tabs(uint numTabs)
{       
    return String.Concat(Enumerable.Repeat("\t", (int) numTabs));
}

I just stumbled in here and I don't see why there is so much code required to achieve this.

Add your CSS code as a string.

let styles = `_x000D_
    font-size:15em;_x000D_
    color:red;_x000D_
    transform:rotate(20deg)`_x000D_
_x000D_
document.querySelector('*').style = styles

a

Just enter this simple command:

ls -d */

The equivalent JPA mapping for the DDL ON DELETE CASCADE is cascade=CascadeType.REMOVE. Orphan removal means that dependent entities are removed when the relationship to their "parent" entity is destroyed. For example if a child is removed from a @OneToMany relationship without explicitely removing it in the entity manager.

As of writing, October 2014 - so here is a contemporary solution. Am writing the solution as a Node Module, and have included a test using Mocha and Chai, as well as underscoreJS. You can easily ignore these, and just take the Enum code if preferred.

Seen a lot of posts with overly convoluted libraries etc. The solution to getting enum support in Javascript is so simple it really isn't needed. Here is the code:

File: enums.js

_ = require('underscore');

var _Enum = function () {

   var keys = _.map(arguments, function (value) {
      return value;
   });
   var self = {
      keys: keys
   };
   for (var i = 0; i < arguments.length; i++) {
      self[keys[i]] = i;
   }
   return self;
};

var fileFormatEnum = Object.freeze(_Enum('CSV', 'TSV'));
var encodingEnum = Object.freeze(_Enum('UTF8', 'SHIFT_JIS'));

exports.fileFormatEnum = fileFormatEnum;
exports.encodingEnum = encodingEnum;

And a test to illustrate what it gives you:

file: enumsSpec.js

var chai = require("chai"),
    assert = chai.assert,
    expect = chai.expect,
    should = chai.should(),
    enums = require('./enums'),
    _ = require('underscore');


describe('enums', function () {

    describe('fileFormatEnum', function () {
        it('should return expected fileFormat enum declarations', function () {
            var fileFormatEnum = enums.fileFormatEnum;
            should.exist(fileFormatEnum);
            assert('{"keys":["CSV","TSV"],"CSV":0,"TSV":1}' === JSON.stringify(fileFormatEnum), 'Unexpected format');
            assert('["CSV","TSV"]' === JSON.stringify(fileFormatEnum.keys), 'Unexpected keys format');
        });
    });

    describe('encodingEnum', function () {
        it('should return expected encoding enum declarations', function () {
            var encodingEnum = enums.encodingEnum;
            should.exist(encodingEnum);
            assert('{"keys":["UTF8","SHIFT_JIS"],"UTF8":0,"SHIFT_JIS":1}' === JSON.stringify(encodingEnum), 'Unexpected format');
            assert('["UTF8","SHIFT_JIS"]' === JSON.stringify(encodingEnum.keys), 'Unexpected keys format');
        });
    });

});

As you can see, you get an Enum factory, you can get all the keys simply by calling enum.keys, and you can match the keys themselves to integer constants. And you can reuse the factory with different values, and export those generated Enums using Node's modular approach.

Once again, if you are just a casual user, or in the browser etc, just take the factory part of the code, potentially removing underscore library too if you don't wish to use it in your code.

Use an URL instead of File for any access that is not on your local computer.

URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
Scanner s = new Scanner(url.openStream());

Actually, URL is even more generally useful, also for local access (use a file: URL), jar files, and about everything that one can retrieve somehow.

The way above interprets the file in your platforms default encoding. If you want to use the encoding indicated by the server instead, you have to use a URLConnection and parse it's content type, like indicated in the answers to this question.

About your Error, make sure your file compiles without any errors - you need to handle the exceptions. Click the red messages given by your IDE, it should show you a recommendation how to fix it. Do not start a program which does not compile (even if the IDE allows this).

Here with some sample exception-handling:

try {
   URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
   Scanner s = new Scanner(url.openStream());
   // read from your scanner
}
catch(IOException ex) {
   // there was some connection problem, or the file did not exist on the server,
   // or your URL was not in the right format.
   // think about what to do now, and put it here.
   ex.printStackTrace(); // for now, simply output it.
}

To correctly save the instance state of Fragment you should do the following:

1. In the fragment, save instance state by overriding onSaveInstanceState() and restore in onActivityCreated():

class MyFragment extends Fragment {

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ...
        if (savedInstanceState != null) {
            //Restore the fragment's state here
        }
    }
    ...
    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        //Save the fragment's state here
    }

}

2. And important point, in the activity, you have to save the fragment's instance in onSaveInstanceState() and restore in onCreate().

class MyActivity extends Activity {

    private MyFragment 

    public void onCreate(Bundle savedInstanceState) {
        ...
        if (savedInstanceState != null) {
            //Restore the fragment's instance
            mMyFragment = getSupportFragmentManager().getFragment(savedInstanceState, "myFragmentName");
            ...
        }
        ...
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        //Save the fragment's instance
        getSupportFragmentManager().putFragment(outState, "myFragmentName", mMyFragment);
    }

}

Hope this helps.

For straight HTML, with no JavaScript required:

<a href="#something">Add '#something' to URL</a>

Or, to take your question more literally, to just add '#' to the URL:

<a href="#">Add '#' to URL</a>

I wrote a package (https://github.com/alexsanjoseph/compareDF) since I had the same issue.

  > df1 <- data.frame(a = 1:5, b=letters[1:5], row = 1:5)
  > df2 <- data.frame(a = 1:3, b=letters[1:3], row = 1:3)
  > df_compare = compare_df(df1, df2, "row")

  > df_compare$comparison_df
    row chng_type a b
  1   4         + 4 d
  2   5         + 5 e

A more complicated example:

library(compareDF)
df1 = data.frame(id1 = c("Mazda RX4", "Mazda RX4 Wag", "Datsun 710",
                         "Hornet 4 Drive", "Duster 360", "Merc 240D"),
                 id2 = c("Maz", "Maz", "Dat", "Hor", "Dus", "Mer"),
                 hp = c(110, 110, 181, 110, 245, 62),
                 cyl = c(6, 6, 4, 6, 8, 4),
                 qsec = c(16.46, 17.02, 33.00, 19.44, 15.84, 20.00))

df2 = data.frame(id1 = c("Mazda RX4", "Mazda RX4 Wag", "Datsun 710",
                         "Hornet 4 Drive", " Hornet Sportabout", "Valiant"),
                 id2 = c("Maz", "Maz", "Dat", "Hor", "Dus", "Val"),
                 hp = c(110, 110, 93, 110, 175, 105),
                 cyl = c(6, 6, 4, 6, 8, 6),
                 qsec = c(16.46, 17.02, 18.61, 19.44, 17.02, 20.22))

> df_compare$comparison_df
    grp chng_type                id1 id2  hp cyl  qsec
  1   1         -  Hornet Sportabout Dus 175   8 17.02

The package also has an html_output command for quick checking

df_compare$html_output

Just change the indexes. i and j....in the loop, plus if you're dealing with Strings you have to use concat and initialize the variable to an empty Strong otherwise you'll get an exception.

String string="";
for (int i = 0; i<array.length; i++){
    for (int j = 0; j<array[i].length; j++){
        string = string.concat(array[j][i]);
    } 
}
System.out.println(string)

I had to edit the below file on my Ubuntu 18.04:

/etc/mysql/mysql.conf.d/mysqld.cnf

with

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

and

sudo service mysql restart

This is a vbscript implementation of merge sort.

'@Function Name: Sort
'@Author: Lewis Gordon
'@Creation Date: 4/26/12
'@Description: Sorts a given array either in ascending or descending order, as specified by the
'                order parameter.  This array is then returned at the end of the function.
'@Prerequisites:  An array must be allocated and have all its values inputted.
'@Parameters:
'    $ArrayToSort:  This is the array that is being sorted.
'    $Order:  This is the sorting order that the array will be sorted in.  This parameter 
'                can either    be "ASC" or "DESC" or ascending and descending, respectively.
'@Notes:  This uses merge sort under the hood.  Also, this function has only been tested for
'            integers and strings in the array.  However, this should work for any data type that
'            implements the greater than and less than comparators.  This function also requires
'            that the merge function is also present, as it is needed to complete the sort.
'@Examples:
'    Dim i
'    Dim TestArray(50)
'    Randomize
'    For i=0 to UBound(TestArray)
'        TestArray(i) = Int((100 - 0 + 1) * Rnd + 0)
'    Next
'    MsgBox Join(Sort(TestArray, "DESC"))
'
'@Return value:  This function returns a sorted array in the specified order.

If you are ok with discarding nonconvertible characters, you can use -c flag

iconv -c -t utf8 filename.csv > filename.utf8.csv

and then copy them to your table
