Check the below code hope that you get your parameter

echo $this->uri->segment('3');

You could write a windows service that does nothing but execute your batch file. Since services run in their own desktop session, the command window won't be visible by the user.

For IE you also need to include the second line - width: 100%;

.mydiv img {
    max-width: 100%;
    width: 100%;
}

Use '-R' to backup stored procedures, but also keep in mind that if you want a consistent dump of your database while its being modified you need to use --single-transaction (if you only backup innodb) or --lock-all-tables (if you also need myisam tables)

Working JSFIDDLE

If your form is like

<form action="" method="get" id="hidden-element-test">
      First name: <input type="text" name="fname"><br>
      Last name: <input type="text" name="lname"><br>
      <input type="submit" value="Submit">
</form> 
    <br><br>   
    <button id="add-input">Add hidden input</button>
    <button id="add-textarea">Add hidden textarea</button>

You can add hidden input and textarea to form like this

$(document).ready(function(){

    $("#add-input").on('click', function(){
        $('#hidden-element-test').prepend('<input type="hidden" name="ipaddress" value="192.168.1.201" />');
        alert('Hideen Input Added.');
    });

    $("#add-textarea").on('click', function(){
        $('#hidden-element-test').prepend('<textarea name="instructions" style="display:none;">this is a test textarea</textarea>');
        alert('Hideen Textarea Added.');
    });

});

You have an error in your AJAX function, too much brackets, try instead $.ajax({

You can use CustomMultiChildLayout to draw this kind of layouts. Here you can find a tutorial: How to Create Custom Layout Widgets in Flutter.

If you do not like double quotes like me, this will work for you with single quotes:

$value = Input::get('q');
$books = Book::where('name', 'LIKE', '%' . $value . '%')->limit(25)->get();

return view('pages/search/index', compact('books'));

As of Laravel >= 5.3, best way is to use value:

$groupName = \App\User::where('username',$username)->value('groupName');

or

use App\User;//at top of controller
$groupName = User::where('username',$username)->value('groupName');//inside controller function

Of course you have to create a model User for users table which is most efficient way to interact with database tables in Laravel.

The function below does not change any other part of the string than trying to convert all the first letters of all words (i.e. by the regex definition \w+) to uppercase.

That means it does not necessarily convert words to Titlecase, but does exactly what the title of the question says: "Capitalize First Letter Of Each Word In A String - JavaScript"

• Don't split the string
• determine each word by the regex \w+ that is equivalent to [A-Za-z0-9_]+
  • apply function String.prototype.toUpperCase() only to the first character of each word.

function first_char_to_uppercase(argument) {
  return argument.replace(/\w+/g, function(word) {
    return word.charAt(0).toUpperCase() + word.slice(1);
  });
}

Examples:

first_char_to_uppercase("I'm a little tea pot");
// "I'M A Little Tea Pot"
// This may look wrong to you, but was the intended result for me
// You may wanna extend the regex to get the result you desire, e.g., /[\w']+/

first_char_to_uppercase("maRy hAd a lIttLe LaMb");
// "MaRy HAd A LIttLe LaMb"
// Again, it does not convert words to Titlecase

first_char_to_uppercase(
  "ExampleX: CamelCase/UPPERCASE&lowercase,exampleY:N0=apples"
);
// "ExampleX: CamelCase/UPPERCASE&Lowercase,ExampleY:N0=Apples"

first_char_to_uppercase("…n1=orangesFromSPAIN&&n2!='a sub-string inside'");
// "…N1=OrangesFromSPAIN&&N2!='A Sub-String Inside'"

first_char_to_uppercase("snake_case_example_.Train-case-example…");
// "Snake_case_example_.Train-Case-Example…"
// Note that underscore _ is part of the RegEx \w+

first_char_to_uppercase(
  "Capitalize First Letter of each word in a String - JavaScript"
);
// "Capitalize First Letter Of Each Word In A String - JavaScript"

Edit 2019-02-07: If you want actual Titlecase (i.e. only the first letter uppercase all others lowercase):

function titlecase_all_words(argument) {
  return argument.replace(/\w+/g, function(word) {
    return word.charAt(0).toUpperCase() + word.slice(1).toLowerCase();
  });
}

Examples showing both:

test_phrases = [
  "I'm a little tea pot",
  "maRy hAd a lIttLe LaMb",
  "ExampleX: CamelCase/UPPERCASE&lowercase,exampleY:N0=apples",
  "…n1=orangesFromSPAIN&&n2!='a sub-string inside'",
  "snake_case_example_.Train-case-example…",
  "Capitalize First Letter of each word in a String - JavaScript"
];
for (el in test_phrases) {
  let phrase = test_phrases[el];
  console.log(
    phrase,
    "<- input phrase\n",
    first_char_to_uppercase(phrase),
    "<- first_char_to_uppercase\n",
    titlecase_all_words(phrase),
    "<- titlecase_all_words\n "
  );
}

// I'm a little tea pot <- input phrase
// I'M A Little Tea Pot <- first_char_to_uppercase
// I'M A Little Tea Pot <- titlecase_all_words

// maRy hAd a lIttLe LaMb <- input phrase
// MaRy HAd A LIttLe LaMb <- first_char_to_uppercase
// Mary Had A Little Lamb <- titlecase_all_words

// ExampleX: CamelCase/UPPERCASE&lowercase,exampleY:N0=apples <- input phrase
// ExampleX: CamelCase/UPPERCASE&Lowercase,ExampleY:N0=Apples <- first_char_to_uppercase
// Examplex: Camelcase/Uppercase&Lowercase,Exampley:N0=Apples <- titlecase_all_words

// …n1=orangesFromSPAIN&&n2!='a sub-string inside' <- input phrase
// …N1=OrangesFromSPAIN&&N2!='A Sub-String Inside' <- first_char_to_uppercase
// …N1=Orangesfromspain&&N2!='A Sub-String Inside' <- titlecase_all_words

// snake_case_example_.Train-case-example… <- input phrase
// Snake_case_example_.Train-Case-Example… <- first_char_to_uppercase
// Snake_case_example_.Train-Case-Example… <- titlecase_all_words

// Capitalize First Letter of each word in a String - JavaScript <- input phrase
// Capitalize First Letter Of Each Word In A String - JavaScript <- first_char_to_uppercase
// Capitalize First Letter Of Each Word In A String - Javascript <- titlecase_all_words

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

Cygwin has fully featured fork() on Windows. Thus if using Cygwin is acceptable for you, then the problem is solved in the case performance is not an issue.

Otherwise you can take a look at how Cygwin implements fork(). From a quite old Cygwin's architecture doc:

5.6. Process Creation The fork call in Cygwin is particularly interesting because it does not map well on top of the Win32 API. This makes it very difficult to implement correctly. Currently, the Cygwin fork is a non-copy-on-write implementation similar to what was present in early flavors of UNIX.

The first thing that happens when a parent process forks a child process is that the parent initializes a space in the Cygwin process table for the child. It then creates a suspended child process using the Win32 CreateProcess call. Next, the parent process calls setjmp to save its own context and sets a pointer to this in a Cygwin shared memory area (shared among all Cygwin tasks). It then fills in the child's .data and .bss sections by copying from its own address space into the suspended child's address space. After the child's address space is initialized, the child is run while the parent waits on a mutex. The child discovers it has been forked and longjumps using the saved jump buffer. The child then sets the mutex the parent is waiting on and blocks on another mutex. This is the signal for the parent to copy its stack and heap into the child, after which it releases the mutex the child is waiting on and returns from the fork call. Finally, the child wakes from blocking on the last mutex, recreates any memory-mapped areas passed to it via the shared area, and returns from fork itself.

While we have some ideas as to how to speed up our fork implementation by reducing the number of context switches between the parent and child process, fork will almost certainly always be inefficient under Win32. Fortunately, in most circumstances the spawn family of calls provided by Cygwin can be substituted for a fork/exec pair with only a little effort. These calls map cleanly on top of the Win32 API. As a result, they are much more efficient. Changing the compiler's driver program to call spawn instead of fork was a trivial change and increased compilation speeds by twenty to thirty percent in our tests.

However, spawn and exec present their own set of difficulties. Because there is no way to do an actual exec under Win32, Cygwin has to invent its own Process IDs (PIDs). As a result, when a process performs multiple exec calls, there will be multiple Windows PIDs associated with a single Cygwin PID. In some cases, stubs of each of these Win32 processes may linger, waiting for their exec'd Cygwin process to exit.

Sounds like a lot of work, doesn't it? And yes, it is slooooow.

EDIT: the doc is outdated, please see this excellent answer for an update

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.

Usage is simple.

string directoryPath = System.IO.Path.GetDirectoryName(choofdlog.FileName);

You can use CTE also like below.

With cte as
(select Activity, SUM(Amount) as "Total Amount 2009"
   from Activities, Incomes
  where Activities.UnitName = ? AND
        Incomes.ActivityId = Activities.ActivityID
  GROUP BY Activity
),
cte1 as 
(select Activity, SUM(Amount) as "Total Amount 2008"
   from Activities, Incomes2008
  where Activities.UnitName = ? AND
        Incomes2008.ActivityId = Activities.ActivityID
  GROUP BY Activity
)
Select cte.Activity, cte.[Total Amount 2009] ,cte1.[Total Amount 2008]      
  from cte join cte1 ON cte.ActivityId = cte1.ActivityID
 WHERE a.UnitName = ?
 ORDER BY cte.Activity 

In my case, just add @ResponseBody annotation to solve this issue.

Answer offered by @faham is a nice one-liner, but it doesn't return the index to the dictionary containing the value. Instead it returns the dictionary itself. Here is a simple way to get: A list of indexes one or more if there are more than one, or an empty list if there are none:

list = [{'id':'1234','name':'Jason'},
        {'id':'2345','name':'Tom'},
        {'id':'3456','name':'Art'}]

[i for i, d in enumerate(list) if 'Tom' in d.values()]

Output:

>>> [1]

What I like about this approach is that with a simple edit you can get a list of both the indexes and the dictionaries as tuples. This is the problem I needed to solve and found these answers. In the following, I added a duplicate value in a different dictionary to show how it works:

list = [{'id':'1234','name':'Jason'},
        {'id':'2345','name':'Tom'},
        {'id':'3456','name':'Art'},
        {'id':'4567','name':'Tom'}]

[(i, d) for i, d in enumerate(list) if 'Tom' in d.values()]

Output:

>>> [(1, {'id': '2345', 'name': 'Tom'}), (3, {'id': '4567', 'name': 'Tom'})]

This solution finds all dictionaries containing 'Tom' in any of their values.

Creating a container and sending commands to it, one by one:

docker create --name=my_new_container -it ubuntu
docker start my_new_container
// ps -a says 'Up X seconds'
docker exec my_new_container /path/to/my/command
// ps -a still says 'Up X+Y seconds'
docker exec my_new_container /path/to/another/command

Instead of '2013-04-12' whose meaning depends on the local culture, use '20130412' which is recognized as the culture invariant format.

If you want to compare with December 4^th, you should write '20131204'. If you want to compare with April 12^th, you should write '20130412'.

The article Write International Transact-SQL Statements from SQL Server's documentation explains how to write statements that are culture invariant:

Applications that use other APIs, or Transact-SQL scripts, stored procedures, and triggers, should use the unseparated numeric strings. For example, yyyymmdd as 19980924.

EDIT

Since you are using ADO, the best option is to parameterize the query and pass the date value as a date parameter. This way you avoid the format issue entirely and gain the performance benefits of parameterized queries as well.

UPDATE

To use the the the ISO 8601 format in a literal, all elements must be specified. To quote from the ISO 8601 section of datetime's documentation

To use the ISO 8601 format, you must specify each element in the format. This also includes the T, the colons (:), and the period (.) that are shown in the format.

... the fraction of second component is optional. The time component is specified in the 24-hour format.

I had the same problem with numpy arrays and the solution is to flatten them:

data = {
    'b': array1.flatten(),
    'a': array2.flatten(),
}

df = pd.DataFrame(data)

This is my solution. When Set-Location fails it throws a non-terminating error which is not seen by the catch block. Adding -ErrorAction Stop is the easiest way around this.

try {
    Set-Location "$YourPath" -ErrorAction Stop;
} catch {
    Write-Host "Exception has been caught";
}

create a filter.js and you can make this as reusable

angular.module('yourmodule').filter('date', function($filter)
{
    return function(input)
    {
        if(input == null){ return ""; }
        var _date = $filter('date')(new Date(input), 'dd/MM/yyyy');
        return _date.toUpperCase();
    };
});

view

<span>{{ d.time | date }}</span>

or in controller

var filterdatetime = $filter('date')( yourdate );

ColorTip is the most beautiful i've ever seen

While I agree that many of the books above are must-reads (Pragmatic Programmer, Mythical Man-Month, Art of Computer Programming, and SICP come to mind immediately), I'd like to go in a slightly different direction and recommend A Discipline of Programming by Edsger Dijkstra. Even though it's 32 years old, the emphasis on "design for verifiability" is highly relevant (even if "verifiability" means "proof" instead "unit tests").

I used this and it worked for me in Laravel 5.3.18:

<?php echo URL::to('resources/assets/css/yourcssfile.css') ?>

IMPORTANT NOTE: This will only work when you have already removed "public" from your URL. To do this, you may check out this helpful tutorial.

In Java, generics are implemented by means of type erasure. For instance, the following code.

List<String> hello = List.of("a", "b");
String example = hello.get(0);

Is compiled to the following.

List hello = List.of("a", "b");
String example = (String) hello.get(0);

And List.of is defined as.

static <E> List<E> of(E e1, E e2);

Which after type erasure becomes.

static List of(Object e1, Object e2);

The compiler has no idea what are generic types at runtime, so if you write something like this.

Object list = List.of("a", "b");
List<Integer> actualList = (List<Integer>) list;

Java Virtual Machine has no idea what generic types are while running a program, so this compiles and runs, as for Java Virtual Machine, this is a cast to List type (this is the only thing it can verify, so it verifies only that).

But now add this line.

Integer hello = actualList.get(0);

And JVM will throw an unexpected ClassCastException, as Java compiler inserted an implicit cast.

java.lang.ClassCastException: java.base/java.lang.String cannot be cast to java.base/java.lang.Integer

An unchecked warning tells a programmer that a cast may cause a program to throw an exception somewhere else. Suppressing the warning with @SuppressWarnings("unchecked") tells the compiler that the programmer believes the code to be safe and won't cause unexpected exceptions.

Why would you want to do that? Java type system isn't good enough to represent all possible type usage patterns. Sometimes you may know that a cast is safe, but Java doesn't provide a way to say so - to hide warnings like this, @SupressWarnings("unchecked") can be used, so that a programmer can focus on real warnings. For instance, Optional.empty() returns a singleton to avoid allocation of empty optionals that don't store a value.

private static final Optional<?> EMPTY = new Optional<>();
public static<T> Optional<T> empty() {
    @SuppressWarnings("unchecked")
    Optional<T> t = (Optional<T>) EMPTY;
    return t;
}

This cast is safe, as the value stored in an empty optional cannot be retrieved so there is no risk of unexpected class cast exceptions.

An easier solution with attributed string extension.

extension NSMutableAttributedString {

    // this function attaches color to string    
    func setColorForText(textToFind: String, withColor color: UIColor) {
        let range: NSRange = self.mutableString.range(of: textToFind, options: .caseInsensitive)
        self.addAttribute(NSAttributedStringKey.foregroundColor, value: color, range: range)
    }

}

Try this and see (Tested in Swift 3 & 4)

let label = UILabel()
label.frame = CGRect(x: 120, y: 100, width: 200, height: 30)
let first = "first"
let second = "second"
let third = "third"
let stringValue = "\(first)\(second)\(third)"  // or direct assign single string value like "firstsecondthird"

let attributedString: NSMutableAttributedString = NSMutableAttributedString(string: stringValue)
attributedString.setColorForText(textToFind: first, withColor: UIColor.red)   // use variable for string "first"
attributedString.setColorForText(textToFind: "second", withColor: UIColor.green) // or direct string like this "second"
attributedString.setColorForText(textToFind: third, withColor: UIColor.blue)
label.font = UIFont.systemFont(ofSize: 26)
label.attributedText = attributedString
self.view.addSubview(label)

Here is expected result:

you can use concat([df1, df2, ...], axis=1) in order to concatenate two or more DFs aligned by indexes:

pd.concat([df1, df2, df3, ...], axis=1)

or merge for concatenating by custom fields / indexes:

# join by _common_ columns: `col1`, `col3`
pd.merge(df1, df2, on=['col1','col3'])

# join by: `df1.col1 == df2.index`
pd.merge(df1, df2, left_on='col1' right_index=True)

or join for joining by index:

 df1.join(df2)

The workaround for Java 7+ is using SimpleDateFormat:
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX", Locale.US);

This code can parse ISO8601 format like:

• 2017-05-17T06:01:43.785Z
• 2017-05-13T02:58:21.391+01:00

But on Java6, SimpleDateFormat doesn't understand X character and will throw
IllegalArgumentException: Unknown pattern character 'X'
We need to normalize ISO8601 date to the format readable in Java 6 with SimpleDateFormat.

public static Date iso8601Format(String formattedDate) throws ParseException {
    try {
        DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX", Locale.US);
        return df.parse(formattedDate);
    } catch (IllegalArgumentException ex) {
        // error happen in Java 6: Unknown pattern character 'X'
        if (formattedDate.endsWith("Z")) formattedDate = formattedDate.replace("Z", "+0000");
        else formattedDate = formattedDate.replaceAll("([+-]\\d\\d):(\\d\\d)\\s*$", "$1$2");
        DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ", Locale.US);
        return df1.parse(formattedDate);
    }
}

Method above to replace [Z with +0000] or [+01:00 with +0100] when error occurs in Java 6 (you can detect Java version and replace try/catch with if statement).

I am not very sure whether it will make any difference in performance of my API.

Bear in mind that the primary benefit of asynchronous code on the server side is scalability. It won't magically make your requests run faster. I cover several "should I use async" considerations in my article on async ASP.NET.

I think your use case (calling other APIs) is well-suited for asynchronous code, just bear in mind that "asynchronous" does not mean "faster". The best approach is to first make your UI responsive and asynchronous; this will make your app feel faster even if it's slightly slower.

As far as the code goes, this is not asynchronous:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
  var response = _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
  return Task.FromResult(response);
}

You'd need a truly asynchronous implementation to get the scalability benefits of async:

public async Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return await _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Or (if your logic in this method really is just a pass-through):

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Note that it's easier to work from the "inside out" rather than the "outside in" like this. In other words, don't start with an asynchronous controller action and then force downstream methods to be asynchronous. Instead, identify the naturally asynchronous operations (calling external APIs, database queries, etc), and make those asynchronous at the lowest level first (Service.ProcessAsync). Then let the async trickle up, making your controller actions asynchronous as the last step.

And under no circumstances should you use Task.Run in this scenario.

Does anyone see any reason why not to do this?

mystring.Select(Convert.ToByte).ToArray()

So interestingly enough this error "Transport endpoint is not connected" was caused by my having more than one Veracrypt device mounted. I closed the extra device and suddenly I had access to the drive. Hmm..

Note that if you care about speed and do not need to worry about singularities, solve() should be preferred to ginv() because it is much faster, as you can check:

require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)

t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0 

t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1 

One-liner.

i.fa.fa-chevron-right.collapse.in { transform: rotate(180deg); }

In this example it's being used to group collapsible table rows. The only thing you need to do is add the target class name (my-collapse-name) to your icon:

<tr data-toggle="collapse" data-target=".my-collapse-name">
    <th><i class="fa fa-chevron-right my-collapse-name"></span></th>
    <th>Master Row - Title</th>
</tr>
<tr class="collapse my-collapse-name">
    <td></td>
    <td>Detail Row - Content</td>
</tr>

You could accomplish the same with Bootstrap's native caret class by using <span class='caret my-collapse-name'></span> and span.caret.collapse.in { transform: rotate(90deg); }

Here i have updated for swift 3

applicationFrame deprecated from iOS 9

In swift three they have removed () and they have changed few naming convention, you can refer here Link

func windowHeight() -> CGFloat {
    return UIScreen.main.bounds.size.height
}

func windowWidth() -> CGFloat {
    return UIScreen.main.bounds.size.width
}

form: NgForm;

form.reset()

This didn't work for me. It cleared the values but the controls raised an error.

But what worked for me was creating a hidden reset button and clicking the button when we want to clear the form.

<button class="d-none" type="reset" #btnReset>Reset</button>

And on the component, define the ViewChild and reference it in code.

@ViewChild('btnReset') btnReset: ElementRef<HTMLElement>;

Use this to reset the form.

this.btnReset.nativeElement.click();

Notice that the class d-none sets display: none; on the button.

CSRF can be enforced at the view level, which can't be disabled globally.

1. Open your SQL command line and type the following:

   SQL> connect / as sysdba
   

2. Once connected,you can enter the following query to get details of username and password:

   SQL> select username,password from dba_users;
   

3. This will list down the usernames,but passwords would not be visible.But you can identify the particular username and then change the password for that user. For changing the password,use the below query:

   SQL> alter user username identified by password;
   

4. Here username is the name of user whose password you want to change and password is the new password.

If pip install mysqlclient produces an error and you use Ubuntu, try:

sudo apt-get install -y python-dev libmysqlclient-dev && sudo pip install mysqlclient

The only alternative to using a loop is to use recursion.

You can define a method like

public static int sum(List<Integer> ints) {
   return ints.isEmpty() ? 0 : ints.get(0) + ints.subList(1, ints.length());
}

This is very inefficient compared to using a plain loop and can blow up if you have many elements in the list.

An alternative which avoid a stack overflow is to use.

public static int sum(List<Integer> ints) {
    int len = ints.size();
    if (len == 0) return 0;
    if (len == 1) return ints.get(0);
    return sum(ints.subList(0, len/2)) + sum(ints.subList(len/2, len));
}

This is just as inefficient, but will avoid a stack overflow.

The shortest way to write the same thing is

int sum = 0, a[] = {2, 4, 6, 8};

for(int i: a) {
    sum += i;
}

System.out.println("sum(a) = " + sum);

prints

sum(a) = 20

Creating .exe distributions isn't typical for Java. While such wrappers do exist, the normal mode of operation is to create a .jar file.

To create a .jar file from a Java project in Eclipse, use file->export->java->Jar file. This will create an archive with all your classes.

On the command prompt, use invocation like the following:

java -cp myapp.jar foo.bar.MyMainClass

A better way, use getParent() from File Class..

String a="/root/sdcard/Pictures/img0001.jpg"; // A valid file path 
File file = new File(a); 
String getDirectoryPath = file.getParent(); // Only return path if physical file exist else return null

http://developer.android.com/reference/java/io/File.html#getParent%28%29

If you are using jQuery you can easily check the type of any element.

    function(elementID){    
    var type = $(elementId).attr('type');
    if(type == "text") //inputBox
     console.log("input text" + $(elementId).val().size());
   }

similarly you can check the other types and take appropriate action.

Pure bash, done in two separate operations:

1. Remove the path from a path-string:

2. Remove the extension from a path-string:

   base=${file%.*}
   #${base} is now 'file'.
   

Similar with Bozho above. You can do some workaround here (although i myself don't like it) through this method :

public <T> List<T> convert(List list, T t){
    return list;
}

Yes. It will cast your list into your demanded generic type.

In the given case above, you can do some code like this :

    List<Object> list = getList();
    return convert(list, new Customer());

I suggest you use an underscore instead of a hyphen (-), since ...

<form name="myForm">
  <input name="myInput" id="my-Id" value="myValue"/>
</form>

<script>
  var x = document.myForm.my-Id.value;
  alert(x);
</script>

you can access the value by id easily in like that. But if you use a hyphen it will cause a syntax error.

This is an old sample, but it can work without jquery -:)

thanks to @jean_ralphio, there is work around way to avoid by

var x = document.myForm['my-Id'].value;

Dash-style would be a google code style, but I don't really like it. I would prefer TitleCase for id and camelCase for class.

If you don't need to do it programatically, but just want to manage your keys, then I've used IBM's free KeyMan tool for a long time now. Very nice for exporting a private key to a PFX file (then you can easily use OpenSSL to manipulate it, extract it, change pwds, etc).

https://www.ibm.com/developerworks/mydeveloperworks/groups/service/html/communityview?communityUuid=6fb00498-f6ea-4f65-bf0c-adc5bd0c5fcc

Select your keystore, select the private key entry, then File->Save to a pkcs12 file (*.pfx, typically). You can then view the contents with:

$ openssl pkcs12 -in mykeyfile.pfx -info

If "budget" has any NaN values but you don't want it to sum to NaN then try:

def fun (b, a):
    if math.isnan(b):
        return a
    else:
        return b + a

f = np.vectorize(fun, otypes=[float])

df['variance'] = f(df['budget'], df_Lp['actual'])

I always use object, it is more easily extendable, JSON array is not. For example you originally had some data as a json array, then you needed to add a status header on it you'd be a bit stuck, unless you'd nested the data in an object. The only disadvantage is a slight increase in complexity of creation / parsing.

So instead of

[datum0, datum1, datumN]

You'd have

{data: [datum0, datum1, datumN]}

then later you can add more...

{status: "foo", data: [datum0, datum1, datumN]}

Using scan should do the trick:

string.scan(/regex/)

In Windows 10 do the following steps: - Download and install the 'Everything' application that locates files and folders by name instantly. - Find the 'devenv.exe' and locate it.

• Right-click on 'devenv.exe' and select "Troubleshoot compatibility". Then select "Troubleshoot program". Then check "The program requires additional permissions". Then test the setting and save setting in next page.

Application Verifier combined with Debugging Tools for Windows is an amazing setup. You can get both as a part of the Windows Driver Kit or the lighter Windows SDK. (Found out about Application Verifier when researching an earlier question about a heap corruption issue.) I've used BoundsChecker and Insure++ (mentioned in other answers) in the past too, although I was surprised how much functionality was in Application Verifier.

Electric Fence (aka "efence"), dmalloc, valgrind, and so forth are all worth mentioning, but most of these are much easier to get running under *nix than Windows. Valgrind is ridiculously flexible: I've debugged large server software with many heap issues using it.

When all else fails, you can provide your own global operator new/delete and malloc/calloc/realloc overloads -- how to do so will vary a bit depending on compiler and platform -- and this will be a bit of an investment -- but it may pay off over the long run. The desirable feature list should look familiar from dmalloc and electricfence, and the surprisingly excellent book Writing Solid Code:

• sentry values: allow a little more space before and after each alloc, respecting maximum alignment requirement; fill with magic numbers (helps catch buffer overflows and underflows, and the occasional "wild" pointer)
• alloc fill: fill new allocations with a magic non-0 value -- Visual C++ will already do this for you in Debug builds (helps catch use of uninitialized vars)
• free fill: fill in freed memory with a magic non-0 value, designed to trigger a segfault if it's dereferenced in most cases (helps catch dangling pointers)
• delayed free: don't return freed memory to the heap for a while, keep it free filled but not available (helps catch more dangling pointers, catches proximate double-frees)
• tracking: being able to record where an allocation was made can sometimes be useful

Note that in our local homebrew system (for an embedded target) we keep the tracking separate from most of the other stuff, because the run-time overhead is much higher.

If you're interested in more reasons to overload these allocation functions/operators, take a look at my answer to "Any reason to overload global operator new and delete?"; shameless self-promotion aside, it lists other techniques that are helpful in tracking heap corruption errors, as well as other applicable tools.

Because I keep finding my own answer here when searching for alloc/free/fence values MS uses, here's another answer that covers Microsoft dbgheap fill values.

I managed to load the local swagger.json specification using the following tools for Node.js and this will take hardly 5 minutes to finish

swagger-ui-dist

express

Follow below steps

1. Create a folder as per your choice and copy your specification swagger.json to the newly created folder
2. Create a file with the extension .js in my case swagger-ui.js in the same newly created folder and copy and save the following content in the file swagger-ui.js

const express = require('express')
const pathToSwaggerUi = require('swagger-ui-dist').absolutePath()
const app = express()

// this is will load swagger ui
app.use(express.static(pathToSwaggerUi))

// this will serve your swagger.json file using express
app.use(express.static(`${__dirname}`))

// use port of your choice
app.listen(5000)

3. Install dependencies as npm install express and npm install swagger-ui-dist
4. Run the express application using the command node swagger-ui.js
5. Open browser and hit http://localhost/5000, this will load swagger ui with default URL as https://petstore.swagger.io/v2/swagger.json
6. Now replace the default URL mentioned above with http://localhost:5000/swagger.json and click on the Explore button, this will load swagger specification from a local JSON file

You can use folder name, JSON file name, static public folder to serve swagger.json, port to serve as per your convenience

echo $var output highly depends on the value of IFS variable. By default it contains space, tab, and newline characters:

[ks@localhost ~]$ echo -n "$IFS" | cat -vte
 ^I$

This means that when shell is doing field splitting (or word splitting) it uses all these characters as word separators. This is what happens when referencing a variable without double quotes to echo it ($var) and thus expected output is altered.

One way to prevent word splitting (besides using double quotes) is to set IFS to null. See http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_06_05 :

If the value of IFS is null, no field splitting shall be performed.

Setting to null means setting to empty value:

IFS=

Test:

[ks@localhost ~]$ echo -n "$IFS" | cat -vte
 ^I$
[ks@localhost ~]$ var=$'key\nvalue'
[ks@localhost ~]$ echo $var
key value
[ks@localhost ~]$ IFS=
[ks@localhost ~]$ echo $var
key
value
[ks@localhost ~]$ 

I found the solution reading the link that Gary gave (and I suggest to follow this way).

Summarizing to resolve the tree conflict committing your working directory with SVN client 1.6.x you can use:

svn resolve --accept working -R .

where . is the directory in conflict.

WARNING: "Committing your working directory" means that your sandbox structure will be the one you are committing, so if, for instance, you deleted some file from your sandbox they will be deleted from the repository too. This applies only to the conflicted directory.

In this way, we are suggesting SVN to resolve the conflict (--resolve), accepting the working copy inside your sandbox (--accept working), recursively (-R), starting from the current directory (.).

In TortoiseSVN, selecting "Resolved" on right click, actually resolves this issue.

ngOnInit() is called after ngOnChanges() was called the first time. ngOnChanges() is called every time inputs are updated by change detection.

ngAfterViewInit() is called after the view is initially rendered. This is why @ViewChild() depends on it. You can't access view members before they are rendered.

This is what I decided to do for my own code:

/**
 * Create a new temporary directory. Use something like
 * {@link #recursiveDelete(File)} to clean this directory up since it isn't
 * deleted automatically
 * @return  the new directory
 * @throws IOException if there is an error creating the temporary directory
 */
public static File createTempDir() throws IOException
{
    final File sysTempDir = new File(System.getProperty("java.io.tmpdir"));
    File newTempDir;
    final int maxAttempts = 9;
    int attemptCount = 0;
    do
    {
        attemptCount++;
        if(attemptCount > maxAttempts)
        {
            throw new IOException(
                    "The highly improbable has occurred! Failed to " +
                    "create a unique temporary directory after " +
                    maxAttempts + " attempts.");
        }
        String dirName = UUID.randomUUID().toString();
        newTempDir = new File(sysTempDir, dirName);
    } while(newTempDir.exists());

    if(newTempDir.mkdirs())
    {
        return newTempDir;
    }
    else
    {
        throw new IOException(
                "Failed to create temp dir named " +
                newTempDir.getAbsolutePath());
    }
}

/**
 * Recursively delete file or directory
 * @param fileOrDir
 *          the file or dir to delete
 * @return
 *          true iff all files are successfully deleted
 */
public static boolean recursiveDelete(File fileOrDir)
{
    if(fileOrDir.isDirectory())
    {
        // recursively delete contents
        for(File innerFile: fileOrDir.listFiles())
        {
            if(!FileUtilities.recursiveDelete(innerFile))
            {
                return false;
            }
        }
    }

    return fileOrDir.delete();
}

You can use the re.sub() function to remove these characters:

>>> import re
>>> re.sub("[^a-zA-Z]+", "", "ABC12abc345def")
'ABCabcdef'

re.sub(MATCH PATTERN, REPLACE STRING, STRING TO SEARCH)

• "[^a-zA-Z]+" - look for any group of characters that are NOT a-zA-z.
• "" - Replace the matched characters with ""

#!/usr/bin/env node

const EventEmitter = require('events');

function stdinLineByLine() {
  const stdin = new EventEmitter();
  let buff = "";

  process.stdin
    .on('data', data => {
      buff += data;
      lines = buff.split(/[\r\n|\n]/);
      buff = lines.pop();
      lines.forEach(line => stdin.emit('line', line));
    })
    .on('end', () => {
      if (buff.length > 0) stdin.emit('line', buff);
    });

  return stdin;
}

const stdin = stdinLineByLine();
stdin.on('line', console.log);

I would really recommend that you go through a tutorial like Sun's Java Concurrency before you commence in the magical world of multithreading.

There are also a number of good books out (google for "Concurrent Programming in Java", "Java Concurrency in Practice".

To get to your answer:

In your code that must wait for the dbThread, you must have something like this:

//do some work
synchronized(objectYouNeedToLockOn){
    while (!dbThread.isReady()){
        objectYouNeedToLockOn.wait();
    }
}
//continue with work after dbThread is ready

In your dbThread's method, you would need to do something like this:

//do db work
synchronized(objectYouNeedToLockOn){
    //set ready flag to true (so isReady returns true)
    ready = true;
    objectYouNeedToLockOn.notifyAll();
}
//end thread run method here

The objectYouNeedToLockOn I'm using in these examples is preferably the object that you need to manipulate concurrently from each thread, or you could create a separate Object for that purpose (I would not recommend making the methods themselves synchronized):

private final Object lock = new Object();
//now use lock in your synchronized blocks

To further your understanding:
There are other (sometimes better) ways to do the above, e.g. with CountdownLatches, etc. Since Java 5 there are a lot of nifty concurrency classes in the java.util.concurrent package and sub-packages. You really need to find material online to get to know concurrency, or get a good book.

Mcrypt PECL extenstion

 sudo apt-get -y install gcc make autoconf libc-dev pkg-config
 sudo apt-get -y install libmcrypt-dev
 sudo pecl install mcrypt-1.0.1

When you are shown the prompt

 libmcrypt prefix? [autodetect] :

Press [Enter] to autodetect.

After success installing mcrypt trought pecl, you should add mcrypt.so extension to php.ini.

The output will look like this:

...
Build process completed successfully
Installing '/usr/lib/php/20170718/mcrypt.so'    ---->   this is our path to mcrypt extension lib
install ok: channel://pecl.php.net/mcrypt-1.0.1
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini

Grab installing path and add to cli and apache2 php.ini configuration.

sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/cli/conf.d/mcrypt.ini"
sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

Verify that the extension was installed

Run command:

php -i | grep "mcrypt"

The output will look like this:

/etc/php/7.2/cli/conf.d/mcrypt.ini
Registered Stream Filters => zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

This will return true if a variable is unset or set to the empty string ("").

if [ -z "$MyVar" ]
then
   echo "The variable MyVar has nothing in it."
elif ! [ -z "$MyVar" ]
then
   echo "The variable MyVar has something in it."

pydoc is fantastic for generating documentation, but the documentation has to be written in the first place. You must have docstrings in your source code as was mentioned by RocketDonkey in the comments:

"""
This example module shows various types of documentation available for use
with pydoc.  To generate HTML documentation for this module issue the
command:

    pydoc -w foo

"""

class Foo(object):
    """
    Foo encapsulates a name and an age.
    """
    def __init__(self, name, age):
        """
        Construct a new 'Foo' object.

        :param name: The name of foo
        :param age: The ageof foo
        :return: returns nothing
        """
        self.name = name
        self.age = age

def bar(baz):
    """
    Prints baz to the display.
    """
    print baz

if __name__ == '__main__':
    f = Foo('John Doe', 42)
    bar("hello world")

The first docstring provides instructions for creating the documentation with pydoc. There are examples of different types of docstrings so you can see how they look when generated with pydoc.

Well, if you are developing a GWT application using Eclipse, then this is the way:

The ValueTuple types are built into newer frameworks:

• .NET Framework 4.7
• .NET Core 2.0
• Mono 5.0
• .Net Standard 2.0

Until you target one of those newer framework versions, you need to reference the ValueTuple package.

You could use a map function that allows multiple arguments, as does the fork of multiprocessing found in pathos.

>>> from pathos.multiprocessing import ProcessingPool as Pool
>>> 
>>> def add_and_subtract(x,y):
...   return x+y, x-y
... 
>>> res = Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))
>>> res
[(-5, 5), (-2, 6), (1, 7), (4, 8), (7, 9), (10, 10), (13, 11), (16, 12), (19, 13), (22, 14)]
>>> Pool().map(add_and_subtract, *zip(*res))
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

pathos enables you to easily nest hierarchical parallel maps with multiple inputs, so we can extend our example to demonstrate that.

>>> from pathos.multiprocessing import ThreadingPool as TPool
>>> 
>>> res = TPool().amap(add_and_subtract, *zip(*Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))))
>>> res.get()
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

Even more fun, is to build a nested function that we can pass into the Pool. This is possible because pathos uses dill, which can serialize almost anything in python.

>>> def build_fun_things(f, g):
...   def do_fun_things(x, y):
...     return f(x,y), g(x,y)
...   return do_fun_things
... 
>>> def add(x,y):
...   return x+y
... 
>>> def sub(x,y):
...   return x-y
... 
>>> neato = build_fun_things(add, sub)
>>> 
>>> res = TPool().imap(neato, *zip(*Pool().map(neato, range(0,20,2), range(-5,5,1))))
>>> list(res)
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

If you are not able to go outside of the standard library, however, you will have to do this another way. Your best bet in that case is to use multiprocessing.starmap as seen here: Python multiprocessing pool.map for multiple arguments (noted by @Roberto in the comments on the OP's post)

Get pathos here: https://github.com/uqfoundation

The best function to use for this is os.path.getmtime(). Internally, this just uses os.stat(filename).st_mtime.

The datetime module is the best manipulating timestamps, so you can get the modification date as a datetime object like this:

import os
import datetime
def modification_date(filename):
    t = os.path.getmtime(filename)
    return datetime.datetime.fromtimestamp(t)

Usage example:

>>> d = modification_date('/var/log/syslog')
>>> print d
2009-10-06 10:50:01
>>> print repr(d)
datetime.datetime(2009, 10, 6, 10, 50, 1)

It depends mostly on how much the repository is used. With one user checking in once a day and a branch/merge/etc operation once a week you probably don't need to run it more than once a year.

With several dozen developers working on several dozen projects each checking in 2-3 times a day, you might want to run it nightly.

It won't hurt to run it more frequently than needed, though.

What I'd do is run it now, then a week from now take a measurement of disk utilization, run it again, and measure disk utilization again. If it drops 5% in size, then run it once a week. If it drops more, then run it more frequently. If it drops less, then run it less frequently.

Parse to your string to a decimal first.

The answer by @.A. Morel I find to be the best easy to understand solution with a small footprint. Just wanted to add on top if you want a smaller code amount this solution which is a modification of Morel works well for not allowing letters of any sort including inputs notorious 'e' character.

function InputTypeNumberDissallowAllCharactersExceptNumeric() {
  let key = Number(inputEvent.key);
  return !isNaN(key);
}

An alternative that might make sense especially if this test is being made multiple times and you are running PHP 7+ and have installed the Set class is:

use Ds\Set;

$strings = new Set(['uk', 'in']);    
if (!$strings->contains($some_variable)) {

Or on any version of PHP you can use an associative array to simulate a set:

$strings = ['uk' => 1, 'in' => 1];
if (!isset($strings[$some_variable])) {

There is additional overhead in creating the set but each test then becomes an O(1) operation. Of course the savings becomes greater the longer the list of strings being compared is.

If I understand you, you can do it with a datetime.timedelta -

import datetime

endTime = datetime.datetime.now() + datetime.timedelta(minutes=15)
while True:
  if datetime.datetime.now() >= endTime:
    break
  # Blah
  # Blah

You do not need to make an extra view for this, the functionality is already built in.

First each page with a login link needs to know the current path, and the easiest way is to add the request context preprosessor to settings.py (the 4 first are default), then the request object will be available in each request:

settings.py:

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.core.context_processors.request",
)

Then add in the template you want the Login link:

base.html:

<a href="{% url django.contrib.auth.views.login %}?next={{request.path}}">Login</a>

This will add a GET argument to the login page that points back to the current page.

The login template can then be as simple as this:

registration/login.html:

{% block content %}
<form method="post" action="">
  {{form.as_p}}
<input type="submit" value="Login">
</form>
{% endblock %}

Like others mentioned, your app runs in a sandboxed environment and you can use the documents directory to store images or other assets your app may use, eg. downloading offline-d files as user prefers - File System Basics - Apple Documentation - Which directory to use, for storing application specific files

Updated to swift 5, you can use one of these functions, as per requirement -

func getDocumentsDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    return paths[0]
}

func getCacheDirectory() -> URL {
        let paths = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask)
        return paths[0]
    }

func getApplicationSupportDirectory() -> URL {
        let paths = FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask)
        return paths[0]
    }

Usage:

let urlPath = "https://jumpcloud.com/wp-content/uploads/2017/06/SSH-Keys.png" //Or string path to some URL of valid image, for eg.

if let url = URL(string: urlPath){
    let destination = getDocumentsDirectory().appendingPathComponent(url.lastPathComponent)
    do {
        let data = try Data(contentsOf: url) //Synchronous call, just as an example
        try data.write(to: destination)
    } catch _ {
        //Do something to handle the error
    }
}

A way to look at advantages of arrays is to see where is the O(1) access capability of arrays is required and hence capitalized:

1. In Look-up tables of your application (a static array for accessing certain categorical responses)

2. Memoization (already computed complex function results, so that you don't calculate the function value again, say log x)

3. High Speed computer vision applications requiring image processing (https://en.wikipedia.org/wiki/Lookup_table#Lookup_tables_in_image_processing)

The following is the same solution of ng5000 but doesn't use P/Invoke.

public static class SuspendUpdate
{
    private const int WM_SETREDRAW = 0x000B;

    public static void Suspend(Control control)
    {
        Message msgSuspendUpdate = Message.Create(control.Handle, WM_SETREDRAW, IntPtr.Zero,
            IntPtr.Zero);

        NativeWindow window = NativeWindow.FromHandle(control.Handle);
        window.DefWndProc(ref msgSuspendUpdate);
    }

    public static void Resume(Control control)
    {
        // Create a C "true" boolean as an IntPtr
        IntPtr wparam = new IntPtr(1);
        Message msgResumeUpdate = Message.Create(control.Handle, WM_SETREDRAW, wparam,
            IntPtr.Zero);

        NativeWindow window = NativeWindow.FromHandle(control.Handle);
        window.DefWndProc(ref msgResumeUpdate);

        control.Invalidate();
    }
}

Both your queries are correct and should give you the right answer.

I would suggest the following query to troubleshoot your problem.

SELECT DISTINCT a,b,c,d,count(*) Count FROM my_table GROUP BY a,b,c,d
order by count(*) desc

That is add count(*) field. This will give you idea how many rows were eliminated using the group command.

Do you really need to do that programmatically?

Just considering the title: You could use a ShapeDrawable as android:background…

For example, let's define res/drawable/my_custom_background.xml as:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:radius="2dp"
      android:topRightRadius="0dp"
      android:bottomRightRadius="0dp"
      android:bottomLeftRadius="0dp" />
  <stroke
      android:width="1dp"
      android:color="@android:color/white" />
</shape>

and define android:background="@drawable/my_custom_background".

I've not tested but it should work.

Update:

I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/border"
    android:padding="10dip" >
    <TextView

Reported to work on a gingerbread device. Note that you'll need to relate android:padding of the LinearLayout to the android:width shape/stroke's value. Please, do not use @android:color/white in your final application but rather a project defined color.

You could apply android:background="@drawable/border" android:padding="10dip" to each of the LinearLayout from your provided sample.

As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…

Your problem resides clearly in the use of getBorder.set{Width,Height}(100);. Why do you do that in an onClick method?

I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.

To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…

From Wikipedia Media type,

A media type is composed of a type, a subtype, and optional parameters. As an example, an HTML file might be designated text/html; charset=UTF-8.

Media type consists of top-level type name and sub-type name, which is further structured into so-called "trees".

top-level type name / subtype name [ ; parameters ]

top-level type name / [ tree. ] subtype name [ +suffix ] [ ; parameters ]

All media types should be registered using the IANA registration procedures. Currently the following trees are created: standard, vendor, personal or vanity, unregistered x.

Standard:

Media types in the standards tree do not use any tree facet (prefix).

type / media type name [+suffix]

Examples: "application/xhtml+xml", "image/png"

Vendor:

Vendor tree is used for media types associated with publicly available products. It uses vnd. facet.

type / vnd. media type name [+suffix] - used in the case of well-known producer

type / vnd. producer's name followed by media type name [+suffix] - producer's name must be approved by IANA

type / vnd. producer's name followed by product's name [+suffix] - producer's name must be approved by IANA

Personal or Vanity tree:

Personal or Vanity tree includes media types created experimentally or as part of products that are not distributed commercially. It uses prs. facet.

type / prs. media type name [+suffix]

Unregistered x. tree:

The "x." tree may be used for media types intended exclusively for use in private, local environments and only with the active agreement of the parties exchanging them. Types in this tree cannot be registered.

According to the previous version of RFC 6838 - obsoleted RFC 2048 (published in November 1996) it should rarely, if ever, be necessary to use unregistered experimental types, and as such use of both "x-" and "x." forms is discouraged. Previous versions of that RFC - RFC 1590 and RFC 1521 stated that the use of "x-" notation for the sub-type name may be used for unregistered and private sub-types, but this recommendation was obsoleted in November 1996.

type / x. media type name [+suffix]

So its clear that the standard type MIME type application/pdf is the appropriate one to use while you should avoid using the obsolete and unregistered x- media type as stated in RFC 2048 and RFC 6838.

There is no difference at all!

1) git checkout -b branch origin/branch

If there is no --track and no --no-track, --track is assumed as default. The default can be changed with the setting branch.autosetupmerge.

In effect, 1) behaves like git checkout -b branch --track origin/branch.

2) git checkout --track origin/branch

“As a convenience”, --track without -b implies -b and the argument to -b is guessed to be “branch”. The guessing is driven by the configuration variable remote.origin.fetch.

In effect, 2) behaves like git checkout -b branch --track origin/branch.

As you can see: no difference.

But it gets even better:

3) git checkout branch

is also equivalent to git checkout -b branch --track origin/branch if “branch” does not exist yet but “origin/branch” does¹.

All three commands set the “upstream” of “branch” to be “origin/branch” (or they fail).

Upstream is used as reference point of argument-less git status, git push, git merge and thus git pull (if configured like that (which is the default or almost the default)).

E.g. git status tells you how far behind or ahead you are of upstream, if one is configured.

git push is configured to push the current branch upstream by default² since git 2.0.

^{1 ...and if “origin” is the only remote having “branch”
2 the default (named “simple”) also enforces for both branch names to be equal}

The best thing hands down that I have tried is LINQ to XSD (which is unknown to most developers). You give it an XSD Schema and it generates a perfectly mapped complete strongly-typed object model (based on LINQ to XML) for you in the background, which is really easy to work with - and it updates and validates your object model and XML in real-time. While it's still "Preview", I have not encountered any bugs with it.

If you have an XSD Schema that looks like this:

  <xs:element name="RootElement">
     <xs:complexType>
      <xs:sequence>
        <xs:element name="Element1" type="xs:string" />
        <xs:element name="Element2" type="xs:string" />
      </xs:sequence>
       <xs:attribute name="Attribute1" type="xs:integer" use="optional" />
       <xs:attribute name="Attribute2" type="xs:boolean" use="required" />
     </xs:complexType>
  </xs:element>

Then you can simply build XML like this:

RootElement rootElement = new RootElement;
rootElement.Element1 = "Element1";
rootElement.Element2 = "Element2";
rootElement.Attribute1 = 5;
rootElement.Attribute2 = true;

Or simply load an XML from file like this:

RootElement rootElement = RootElement.Load(filePath);

Or save it like this:

rootElement.Save(string);
rootElement.Save(textWriter);
rootElement.Save(xmlWriter);

rootElement.Untyped also yields the element in form of a XElement (from LINQ to XML).

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

The Best Order I've seen :

// SearchList is your List  
// TEXT is your Search Text
// SubList is your result

                    ArrayList<String> TempList = new ArrayList<String>(
                            (SearchList));
                    int temp = 0;
                    int num = 0;
                    ArrayList<String> SubList = new ArrayList<String>();
                    while (temp > -1) {
                        temp = TempList.indexOf(new Object() {
                            @Override
                            public boolean equals(Object obj) {
                                return obj.toString().startsWith(TEXT);
                            }
                        });
                        if (temp > -1) {
                         SubList.add(SearchList.get(temp + num++));
                         TempList.remove(temp);
                        }
                    }

Use:

list.removeAll(...);
//post what char you need in the ... section

Seems reflection only help here.. I've done small example of converting object to dictionary and vise versa:

[TestMethod]
public void DictionaryTest()
{
    var item = new SomeCLass { Id = "1", Name = "name1" };
    IDictionary<string, object> dict = ObjectToDictionary<SomeCLass>(item);
    var obj = ObjectFromDictionary<SomeCLass>(dict);
}

private T ObjectFromDictionary<T>(IDictionary<string, object> dict)
    where T : class 
{
    Type type = typeof(T);
    T result = (T)Activator.CreateInstance(type);
    foreach (var item in dict)
    {
        type.GetProperty(item.Key).SetValue(result, item.Value, null);
    }
    return result;
}

private IDictionary<string, object> ObjectToDictionary<T>(T item)
    where T: class
{
    Type myObjectType = item.GetType();
    IDictionary<string, object> dict = new Dictionary<string, object>();
    var indexer = new object[0];
    PropertyInfo[] properties = myObjectType.GetProperties();
    foreach (var info in properties)
    {
        var value = info.GetValue(item, indexer);
        dict.Add(info.Name, value);
    }
    return dict;
}

You can run this in powershell:

[System.Runtime.InteropServices.RuntimeEnvironment]::SystemConfigurationFile

Which outputs this for .net 4:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\config\machine.config

Note however that this might change depending on whether .net is running as 32 or 64 bit which will result in \Framework\ or \Framework64\ respectively.

heres a step by step procedure (assuming you've already installed python):

1. first install chocolatey:

open terminal (Run as Administrator) and type in the command line:

C:/> @powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

it will take some time to get chocolatey installed on your machine. sit back n relax...

2. now install pip. type in terminal cinst easy.install pip

3. now type in terminal: pip install flask

YOU'RE DONE !!! Tested on Win 8.1 with Python 2.7

The netdom.exe command line program can be used. This is available from the Windows XP Support Tools or Server 2003 Support Tools (both on the installation CD).

Usage guidelines here

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

Output is buffered.

stdout is line-buffered by default, which means that '\n' is supposed to flush the buffer. Why is it not happening in your case? I don't know. I need more info about your application/environment.

However, you can control buffering with setvbuf():

setvbuf(stdout, NULL, _IOLBF, 0);

This will force stdout to be line-buffered.

setvbuf(stdout, NULL, _IONBF, 0);

This will force stdout to be unbuffered, so you won't need to use fflush(). Note that it will severely affect application performance if you have lots of prints.

char* str = "HELLO";
char c = str[1];

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.

I am shamelessly copying the excerpts from man page of top

VIRT -- Virtual Image (kb) The total amount of virtual memory used by the task. It includes all code, data and shared libraries plus pages that have been swapped out and pages that have been mapped but not used.

SWAP -- Swapped size (kb) Memory that is not resident but is present in a task. This is memory that has been swapped out but could include additional non- resident memory. This column is calculated by subtracting physical memory from virtual memory

Basically the zip function works on lists, tuples and dictionaries in Python. If you are using IPython then just type zip? And check what zip() is about.

If you are not using IPython then just install it: "pip install ipython"

For lists

a = ['a', 'b', 'c']
b = ['p', 'q', 'r']
zip(a, b)

The output is [('a', 'p'), ('b', 'q'), ('c', 'r')

For dictionary:

c = {'gaurav':'waghs', 'nilesh':'kashid', 'ramesh':'sawant', 'anu':'raje'}
d = {'amit':'wagh', 'swapnil':'dalavi', 'anish':'mane', 'raghu':'rokda'}
zip(c, d)

The output is:

[('gaurav', 'amit'),
 ('nilesh', 'swapnil'),
 ('ramesh', 'anish'),
 ('anu', 'raghu')]

Foreign Key Constraint Names Have to be Unique Within a Database

Both @Dorvalla’s answer and this blog post mentioned above pointed me into the right direction to fix the problem for myself; quoting from the latter:

If the table you're trying to create includes a foreign key constraint, and you've provided your own name for that constraint, remember that it must be unique within the database.

I wasn’t aware of that. I have changed my foreign key constraint names according to the following schema which appears to be used by Ruby on Rails applications, too:

<TABLE_NAME>_<FOREIGN_KEY_COLUMN_NAME>_fk

For the OP’s table this would be Link_lession_id_fk, for example.

You should define a key name while storing data to local storage which should be a string and value should be a string

 localStorage.setItem('dataSource', this.dataSource.length);

and to print, you should use getItem

console.log(localStorage.getItem('dataSource'));

You want multiple lines of text indented on the left. Try the following:

CSS:

div.info {
    margin-left: 10px;
}

span.info {
    color: #b1b1b1;
    font-size: 11px;
    font-style: italic;
    font-weight:bold;
}

HTML:

<div class="info"><span class="info">blah blah <br/> blah blah</span></div>

I asked a similar question (C++ openframeworks passing void from other classes) but the answer I found was clearer so here the explanation for future records:

it’s easier to use std::function as in:

 void draw(int grid, std::function<void()> element)

and then call as:

 grid.draw(12, std::bind(&BarrettaClass::draw, a, std::placeholders::_1));

or even easier:

  grid.draw(12, [&]{a.draw()});

where you create a lambda that calls the object capturing it by reference

just fetch specific node data and its working perfect for me

mFirebaseInstance.getReference("yourNodeName").getRef().addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {


        for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
            Log.e(TAG, "======="+postSnapshot.child("email").getValue());
            Log.e(TAG, "======="+postSnapshot.child("name").getValue());
        }
    }

    @Override
    public void onCancelled(DatabaseError error) {
        // Failed to read value
        Log.e(TAG, "Failed to read app title value.", error.toException());
    }
});

There are a few existing resources you might check:

1. Properly Package Your Java Classes
2. Spring 2.5 Architecture
3. Java Tutorial - Naming a Package
4. SUN Naming Conventions

For what it's worth, my own personal guidelines that I tend to use are as follows:

1. Start with reverse domain, e.g. "com.mycompany".
2. Use product name, e.g. "myproduct". In some cases I tend to have common packages that do not belong to a particular product. These would end up categorized according to the functionality of these common classes, e.g. "io", "util", "ui", etc.
3. After this it becomes more free-form. Usually I group according to project, area of functionality, deployment, etc. For example I might have "project1", "project2", "ui", "client", etc.

A couple of other points:

1. It's quite common in projects I've worked on for package names to flow from the design documentation. Usually products are separated into areas of functionality or purpose already.
2. Don't stress too much about pushing common functionality into higher packages right away. Wait for there to be a need across projects, products, etc., and then refactor.
3. Watch inter-package dependencies. They're not all bad, but it can signify tight coupling between what might be separate units. There are tools that can help you keep track of this.

gethostname() using the IP from $_SERVER['REMOTE_ADDR'] while accessing the script remotely will return the IP of your internet connection, not your computer.

Personally I preferred to insert a 1. * at the very beginning. So the expression become something like this:

1. * (20-10) / (100-10)

As I always do a division for some formula like:

accuracy = 1. * (len(y_val) - sum(y_val)) / len(y_val)

so it is impossible to simply add a .0 like 20.0. And in my case, wrapping with a float() may lose a little bit readability.

Use continue statement instead of return to skip an iteration in JS loops.

The code you have posted here and code on your site both are different. There is a break <br> after second image, so the third image into new line, remove this <br> and it will display correctly.

The recommended version by Günter Zöchbauer works fine, but I have an addition to make. In my case I had an unstyled html-element and I did not know how to style it. Therefore I designed a pipe to add styling to it.

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml } from '@angular/platform-browser';


@Pipe({
    name: 'StyleClass'
})
export class StyleClassPipe implements PipeTransform {

    constructor(private sanitizer: DomSanitizer) { }
    transform(html: any, styleSelector: any, styleValue: any): SafeHtml {
        const style = ` style = "${styleSelector}: ${styleValue};"`;
        const indexPosition = html.indexOf('>');
        const newHtml = [html.slice(0, indexPosition), style, html.slice(indexPosition)].join('');
        return this.sanitizer.bypassSecurityTrustHtml(newHtml);
    }

}

Then you can add style to any html-element like this:

<span [innerhtml]="Variable | StyleClass: 'margin': '0'"> </span>

With:

Variable = '<p> Test </p>'

I think that you can use

$file= public_path(). "/download/info.pdf";

$headers = array(
        'Content-Type: ' . mime_content_type( $file ),
    );

With this you be sure that is a pdf.

//this should allow you to replica an animation effect for any css property, even //properties //that transform animation jQuery plugins do not allow

            function twistMyElem(){
                var ball = $('#form');
                document.getElementById('form').style.zIndex = 1;
                ball.animate({ zIndex : 360},{
                    step: function(now,fx){
                        ball.css("transform","rotateY(" + now + "deg)");
                    },duration:3000
                }, 'linear');
            } 

I needed a quick way to get rid of the +4 from a zip code.

No proc... no UDF... just one tight little inline command that does what it must. Not fancy, not elegant.

Change the delimiter as needed, etc, and it will work for anything.

Just simply 'export' variable and 'import' in your class

export var GOOGLE_API_URL = 'https://www.googleapis.com/admin/directory/v1';

// default err string message
export var errStringMsg = 'Something went wrong';

Now use it as,

import appConstants = require('../core/AppSettings');
console.log(appConstants.errStringMsg);
console.log(appConstants.GOOGLE_API_URL);

For me the sdk version mentioned in build.gradle wasn't installed. Used SDK Manager to install the right SDK version and it worked

Call the std::exit function.   

This can happen when invoking a method that doesn't exist.

The goal you indicate in the command line is linked to the lifecycle of Maven. For example, the build lifecycle (you also have the clean and site lifecycles which are different) is composed of the following phases:

• validate: validate the project is correct and all necessary information is available.
• compile: compile the source code of the project.
• test: test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed.
• package: take the compiled code and package it in its distributable format, such as a JAR.
• integration-test: process and deploy the package if necessary into an environment where integration tests can be run.
• verify: run any checks to verify the package is valid and meets quality criteria
• install: install the package into the local repository, for use as a dependency in other projects locally.
• deploy: done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

You can find the list of "core" plugins here, but there are plenty of others plugins, such as the codehaus ones, here.

@alessioalex answer is a perfect demo for fresh node user. But anyway, it's hard to write checkAuth middleware into all routes except login, so it's better to move the checkAuth from every route to one entry with app.use. For example:

function checkAuth(req, res, next) {
  // if logined or it's login request, then go next route
  if (isLogin || (req.path === '/login' && req.method === 'POST')) {
    next()
  } else {
    res.send('Not logged in yet.')
  }
}

app.use('/', checkAuth)

div#father {
    position: relative;

}

• All as varchar (they aren't numbers but "collections of digits")
• Country + area + number separately
• Not all countries have area code (eg Malta where I am)
• Some countries drop the leading zero from the area code when dialling internal (eg UK)
• Format in the client code

To find the difference, you need to get the current date and the date in the future. In the following case, I used 2 days for an example of the future date. Calculated by:

2 days * 24 hours * 60 minutes * 60 seconds. We expect the number of seconds in 2 days to be 172,800.

// Set the current and future date
let now = Date()
let nowPlus2Days = Date(timeInterval: 2*24*60*60, since: now)

// Get the number of seconds between these two dates
let secondsInterval = DateInterval(start: now, end: nowPlus2Days).duration

print(secondsInterval) // 172800.0

In this case you can use a === undefined comparison: if(val === undefined)

This works because val always exists (it's a function argument).

If you wanted to test an arbitrary variable that is not an argument, i.e. might not be defined at all, you'd have to use if(typeof val === 'undefined') to avoid an exception in case val didn't exist.

One issue could be that if either make, model, or [serial number] were null, values would never get returned. Because string concatenations with null values always result in null, and not in () with null will always return nothing. The remedy for this is to use an operator such as IsNull(make, '') + IsNull(Model, ''), etc.

It's true, they are both - or more precisely, they are "inline block" elements. This means that they flow inline like text, but also have a width and height like block elements.

In CSS, you can set an element to display: inline-block to make it replicate the behaviour of images*.

Images and objects are also known as "replaced" elements, since they do not have content per se, the element is essentially replaced by binary data.

* Note that browsers technically use display: inline (as seen in the developer tools) but they are giving special treatment to images. They still follow all traits of inline-block.

Well, you can create your own type - but a DateTime always has a full date and time. You can't even have "just a date" using DateTime - the closest you can come is to have a DateTime at midnight.

You could always ignore the year though - or take the current year:

// Consider whether you want DateTime.UtcNow.Year instead
DateTime value = new DateTime(DateTime.Now.Year, month, day);

To create your own type, you could always just embed a DateTime within a struct, and proxy on calls like AddDays etc:

public struct MonthDay : IEquatable<MonthDay>
{
    private readonly DateTime dateTime;

    public MonthDay(int month, int day)
    {
        dateTime = new DateTime(2000, month, day);
    }

    public MonthDay AddDays(int days)
    {
        DateTime added = dateTime.AddDays(days);
        return new MonthDay(added.Month, added.Day);
    }

    // TODO: Implement interfaces, equality etc
}

Note that the year you choose affects the behaviour of the type - should Feb 29th be a valid month/day value or not? It depends on the year...

Personally I don't think I would create a type for this - instead I'd have a method to return "the next time the program should be run".

$sql = "SELECT * FROM table_name ORDER BY ID DESC LIMIT 1";
$records = mysql_query($sql);

you can change LIMIT 1 to LIMIT any number you want

This will show you the last INSERTED row first.

If I am not wrong, it's more or less similar to

What is the difference between an interface and abstract class?

extends establishes "Is A" relation & interface provides "Has a" capability.

Prefer implements Runnable :

1. If you don't have to extend Thread class and modify Thread API default implementation
2. If you are executing a fire and forget command
3. If You are already extending another class

Prefer "extends Thread" :

1. If you have to override any of these Thread methods as listed in oracle documentation page

Generally you don't need to override Thread behaviour. So implements Runnable is preferred for most of the times.

On a different note, using advanced ExecutorService or ThreadPoolExecutorService API provides more flexibility and control.

Have a look at this SE Question:

By default activation function is "Relu". It could be possible that intermediate layer's generating a negative value and "Relu" convert it into the 0. Which gradually stops training.

I observed the "LeakyRelu" able to solve such problems.

In pyspark,SparkSql syntax:

where column_n like 'xyz%'

might not work.

Use:

where column_n RLIKE '^xyz' 

This works perfectly fine.

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

import pandas as pd

a = ['2015-01-01' , '2015-02-01']

df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})

print(df)
#         date
#0  2015-01-01
#1  2015-02-01
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

df = df[~df['date'].isin(a)]

print(df)
#         date
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

As said before, VBA does not support Multithreading.

But you don't need to use C# or vbScript to start other VBA worker threads.

I use VBA to create VBA worker threads.

First copy the makro workbook for every thread you want to start.

Then you can start new Excel Instances (running in another Thread) simply by creating an instance of Excel.Application (to avoid errors i have to set the new application to visible).

To actually run some task in another thread i can then start a makro in the other application with parameters form the master workbook.

To return to the master workbook thread without waiting i simply use Application.OnTime in the worker thread (where i need it).

As semaphore i simply use a collection that is shared with all threads. For callbacks pass the master workbook to the worker thread. There the runMakroInOtherInstance Function can be reused to start a callback.

'Create new thread and return reference to workbook of worker thread
Public Function openNewInstance(ByVal fileName As String, Optional ByVal openVisible As Boolean = True) As Workbook
    Dim newApp As New Excel.Application
    ThisWorkbook.SaveCopyAs ThisWorkbook.Path & "\" & fileName
    If openVisible Then newApp.Visible = True
    Set openNewInstance = newApp.Workbooks.Open(ThisWorkbook.Path & "\" & fileName, False, False) 
End Function

'Start macro in other instance and wait for return (OnTime used in target macro)
Public Sub runMakroInOtherInstance(ByRef otherWkb As Workbook, ByVal strMakro As String, ParamArray var() As Variant)
    Dim makroName As String
    makroName = "'" & otherWkb.Name & "'!" & strMakro
    Select Case UBound(var)
        Case -1:
            otherWkb.Application.Run makroName
        Case 0:
            otherWkb.Application.Run makroName, var(0)
        Case 1:
            otherWkb.Application.Run makroName, var(0), var(1)
        Case 2:
            otherWkb.Application.Run makroName, var(0), var(1), var(2)
        Case 3:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3)
        Case 4:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3), var(4)
        Case 5:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3), var(4), var(5)

You forgot the ending brace to this if statement, so the subsequent else if is considered a syntax error. You need to add the brace when the if statement body is complete:

}
else if (moustaches) {

Continuing the evolution of this solution I've upped the ante by adding support for multiple root selections and deeper nested selections. This is a further development of JavierCane's solution (which in turn built on tarheel's).

As Javier says:

• Create the sheet where you'll have the nested selectors
• Go to the "Tools" > "Script Editor…" and select the "Blank project" option
• Paste the code attached to this answer
• Modify the constants at the top of the script setting up your values and save it
• Create one sheet within this same document for each possible value of the "root selector". They must be named as the value + the specified suffix.

And if you wanted to see it in action I've created a demo sheet and you can see the code if you take a copy.

• getattr(x, 'y') is equivalent to x.y
• setattr(x, 'y', v) is equivalent to x.y = v
• delattr(x, 'y') is equivalent to del x.y

I just got another case to display backslash \ with Razor and Java Script.

My @Model.AreaName looks like Name1\Name2\Name3 so when I display it all backslashes are gone and I see Name1Name2Name3

I found solution to fix it:

var areafullName =  JSON.parse("@Html.Raw(HttpUtility.JavaScriptStringEncode(JsonConvert.SerializeObject(Model.AreaName)))");

Don't forget to add @using Newtonsoft.Json on top of chtml page.

You can reset your root password. Have in mind that it is not advisable to use root without password.

The Classloader API doesn't have an "enumerate" method, because class loading is an "on-demand" activity -- you usually have thousands of classes in your classpath, only a fraction of which will ever be needed (the rt.jar alone is 48MB nowadays!).

So, even if you could enumerate all classes, this would be very time- and memory-consuming.

The simple approach is to list the concerned classes in a setup file (xml or whatever suits your fancy); if you want to do this automatically, restrict yourself to one JAR or one class directory.

@media all and (max-device-width: 400px) {

}

@media all and (max-width: 400px) {
    /* styles for target area with a maximum width of 400px and less
       Changes on device orientation , browser resize */
}

The max-width is the width of the target display area means the current size of browser.

    'If we are near midnight (or specify a very long time!) then finish could be
    'greater than the maximum possible value of timer. Bring it down to sensible
    'levels and count the number of midnights

        finish = finish - 86400
        days = days + 1

Explanation

From PEP 328

Relative imports use a module's __name__ attribute to determine that module's position in the package hierarchy. If the module's name does not contain any package information (e.g. it is set to '__main__') then relative imports are resolved as if the module were a top level module, regardless of where the module is actually located on the file system.

At some point PEP 338 conflicted with PEP 328:

... relative imports rely on __name__ to determine the current module's position in the package hierarchy. In a main module, the value of __name__ is always '__main__', so explicit relative imports will always fail (as they only work for a module inside a package)

and to address the issue, PEP 366 introduced the top level variable __package__:

By adding a new module level attribute, this PEP allows relative imports to work automatically if the module is executed using the -m switch. A small amount of boilerplate in the module itself will allow the relative imports to work when the file is executed by name. [...] When it [the attribute] is present, relative imports will be based on this attribute rather than the module __name__ attribute. [...] When the main module is specified by its filename, then the __package__ attribute will be set to None. [...] When the import system encounters an explicit relative import in a module without __package__ set (or with it set to None), it will calculate and store the correct value (__name__.rpartition('.')[0] for normal modules and __name__ for package initialisation modules)

(emphasis mine)

If the __name__ is '__main__', __name__.rpartition('.')[0] returns empty string. This is why there's empty string literal in the error description:

SystemError: Parent module '' not loaded, cannot perform relative import

The relevant part of the CPython's PyImport_ImportModuleLevelObject function:

if (PyDict_GetItem(interp->modules, package) == NULL) {
    PyErr_Format(PyExc_SystemError,
            "Parent module %R not loaded, cannot perform relative "
            "import", package);
    goto error;
}

CPython raises this exception if it was unable to find package (the name of the package) in interp->modules (accessible as sys.modules). Since sys.modules is "a dictionary that maps module names to modules which have already been loaded", it's now clear that the parent module must be explicitly absolute-imported before performing relative import.

Note: The patch from the issue 18018 has added another if block, which will be executed before the code above:

if (PyUnicode_CompareWithASCIIString(package, "") == 0) {
    PyErr_SetString(PyExc_ImportError,
            "attempted relative import with no known parent package");
    goto error;
} /* else if (PyDict_GetItem(interp->modules, package) == NULL) {
    ...
*/

If package (same as above) is empty string, the error message will be

ImportError: attempted relative import with no known parent package

However, you will only see this in Python 3.6 or newer.

Solution #1: Run your script using -m

Consider a directory (which is a Python package):

.
+-- package
¦   +-- __init__.py
¦   +-- module.py
¦   +-- standalone.py

All of the files in package begin with the same 2 lines of code:

from pathlib import Path
print('Running' if __name__ == '__main__' else 'Importing', Path(__file__).resolve())

I'm including these two lines only to make the order of operations obvious. We can ignore them completely, since they don't affect the execution.

__init__.py and module.py contain only those two lines (i.e., they are effectively empty).

standalone.py additionally attempts to import module.py via relative import:

from . import module  # explicit relative import

We're well aware that /path/to/python/interpreter package/standalone.py will fail. However, we can run the module with the -m command line option that will "search sys.path for the named module and execute its contents as the __main__ module":

vaultah@base:~$ python3 -i -m package.standalone
Importing /home/vaultah/package/__init__.py
Running /home/vaultah/package/standalone.py
Importing /home/vaultah/package/module.py
>>> __file__
'/home/vaultah/package/standalone.py'
>>> __package__
'package'
>>> # The __package__ has been correctly set and module.py has been imported.
... # What's inside sys.modules?
... import sys
>>> sys.modules['__main__']
<module 'package.standalone' from '/home/vaultah/package/standalone.py'>
>>> sys.modules['package.module']
<module 'package.module' from '/home/vaultah/package/module.py'>
>>> sys.modules['package']
<module 'package' from '/home/vaultah/package/__init__.py'>

-m does all the importing stuff for you and automatically sets __package__, but you can do that yourself in the

Solution #2: Set __package__ manually

Please treat it as a proof of concept rather than an actual solution. It isn't well-suited for use in real-world code.

PEP 366 has a workaround to this problem, however, it's incomplete, because setting __package__ alone is not enough. You're going to need to import at least N preceding packages in the module hierarchy, where N is the number of parent directories (relative to the directory of the script) that will be searched for the module being imported.

Thus,

1. Add the parent directory of the Nth predecessor of the current module to sys.path

2. Remove the current file's directory from sys.path

3. Import the parent module of the current module using its fully-qualified name

4. Set __package__ to the fully-qualified name from 2

5. Perform the relative import

I'll borrow files from the Solution #1 and add some more subpackages:

package
+-- __init__.py
+-- module.py
+-- subpackage
    +-- __init__.py
    +-- subsubpackage
        +-- __init__.py
        +-- standalone.py

This time standalone.py will import module.py from the package package using the following relative import

from ... import module  # N = 3

We'll need to precede that line with the boilerplate code, to make it work.

import sys
from pathlib import Path

if __name__ == '__main__' and __package__ is None:
    file = Path(__file__).resolve()
    parent, top = file.parent, file.parents[3]

    sys.path.append(str(top))
    try:
        sys.path.remove(str(parent))
    except ValueError: # Already removed
        pass

    import package.subpackage.subsubpackage
    __package__ = 'package.subpackage.subsubpackage'

from ... import module # N = 3

It allows us to execute standalone.py by filename:

vaultah@base:~$ python3 package/subpackage/subsubpackage/standalone.py
Running /home/vaultah/package/subpackage/subsubpackage/standalone.py
Importing /home/vaultah/package/__init__.py
Importing /home/vaultah/package/subpackage/__init__.py
Importing /home/vaultah/package/subpackage/subsubpackage/__init__.py
Importing /home/vaultah/package/module.py

A more general solution wrapped in a function can be found here. Example usage:

if __name__ == '__main__' and __package__ is None:
    import_parents(level=3) # N = 3

from ... import module
from ...module.submodule import thing

Solution #3: Use absolute imports and setuptools

The steps are -

1. Replace explicit relative imports with equivalent absolute imports

2. Install package to make it importable

For instance, the directory structure may be as follows

.
+-- project
¦   +-- package
¦   ¦   +-- __init__.py
¦   ¦   +-- module.py
¦   ¦   +-- standalone.py
¦   +-- setup.py

where setup.py is

from setuptools import setup, find_packages
setup(
    name = 'your_package_name',
    packages = find_packages(),
)

The rest of the files were borrowed from the Solution #1.

Installation will allow you to import the package regardless of your working directory (assuming there'll be no naming issues).

We can modify standalone.py to use this advantage (step 1):

from package import module  # absolute import

Change your working directory to project and run /path/to/python/interpreter setup.py install --user (--user installs the package in your site-packages directory) (step 2):

vaultah@base:~$ cd project
vaultah@base:~/project$ python3 setup.py install --user

Let's verify that it's now possible to run standalone.py as a script:

vaultah@base:~/project$ python3 -i package/standalone.py
Running /home/vaultah/project/package/standalone.py
Importing /home/vaultah/.local/lib/python3.6/site-packages/your_package_name-0.0.0-py3.6.egg/package/__init__.py
Importing /home/vaultah/.local/lib/python3.6/site-packages/your_package_name-0.0.0-py3.6.egg/package/module.py
>>> module
<module 'package.module' from '/home/vaultah/.local/lib/python3.6/site-packages/your_package_name-0.0.0-py3.6.egg/package/module.py'>
>>> import sys
>>> sys.modules['package']
<module 'package' from '/home/vaultah/.local/lib/python3.6/site-packages/your_package_name-0.0.0-py3.6.egg/package/__init__.py'>
>>> sys.modules['package.module']
<module 'package.module' from '/home/vaultah/.local/lib/python3.6/site-packages/your_package_name-0.0.0-py3.6.egg/package/module.py'>

Note: If you decide to go down this route, you'd be better off using virtual environments to install packages in isolation.

Solution #4: Use absolute imports and some boilerplate code

Frankly, the installation is not necessary - you could add some boilerplate code to your script to make absolute imports work.

I'm going to borrow files from Solution #1 and change standalone.py:

1. Add the parent directory of package to sys.path before attempting to import anything from package using absolute imports:

   import sys
   from pathlib import Path # if you haven't already done so
   file = Path(__file__).resolve()
   parent, root = file.parent, file.parents[1]
   sys.path.append(str(root))
   
   # Additionally remove the current file's directory from sys.path
   try:
       sys.path.remove(str(parent))
   except ValueError: # Already removed
       pass
   

2. Replace the relative import by the absolute import:

   from package import module  # absolute import
   

standalone.py runs without problems:

vaultah@base:~$ python3 -i package/standalone.py
Running /home/vaultah/package/standalone.py
Importing /home/vaultah/package/__init__.py
Importing /home/vaultah/package/module.py
>>> module
<module 'package.module' from '/home/vaultah/package/module.py'>
>>> import sys
>>> sys.modules['package']
<module 'package' from '/home/vaultah/package/__init__.py'>
>>> sys.modules['package.module']
<module 'package.module' from '/home/vaultah/package/module.py'>

I feel that I should warn you: try not to do this, especially if your project has a complex structure.

As a side note, PEP 8 recommends the use of absolute imports, but states that in some scenarios explicit relative imports are acceptable:

Absolute imports are recommended, as they are usually more readable and tend to be better behaved (or at least give better error messages). [...] However, explicit relative imports are an acceptable alternative to absolute imports, especially when dealing with complex package layouts where using absolute imports would be unnecessarily verbose.

Here's my take on this problem.

I have defined a function 'index' which takes the number and the input index and outputs the digit at the desired index.

The enumerate method operates on the strings, therefore the number is first converted to a string. Since the indexing in Python starts from zero, but the desired functionality requires it to start with 1, therefore a 1 is placed in the enumerate function to indicate the start of the counter.

def index(number, i):

    for p,num in enumerate(str(number),1):

        if p == i:
            print(num)

As reported in https://github.com/angular/angular.js/issues/4765, switching from ng-click to ng-change seems to fix this (I am using Angular 1.2.14)

when you want to permit multiple array fields you will have to list array fields at last while permitting ,as given -

params.require(:questions).permit(:question, :user_id, answers: [], selected_answer: [] )

(this works)

You could do this:

class ObjectAType
{
    public int PropertyC
    {
        get
        {
            if (PropertyA == null)
                return 0;
            if (PropertyA.PropertyB == null)
                return 0;
            return PropertyA.PropertyB.PropertyC;
        }
    }
}



if (ObjectA != null)
{
    int value = ObjectA.PropertyC;
    ...
}

Or even better might be this:

private static int GetPropertyC(ObjectAType objectA)
{
    if (objectA == null)
        return 0;
    if (objectA.PropertyA == null)
        return 0;
    if (objectA.PropertyA.PropertyB == null)
        return 0;
    return objectA.PropertyA.PropertyB.PropertyC;
}


int value = GetPropertyC(ObjectA);

A combination of the regex and SimpleDateFormat is the right answer i believe. SimpleDateFormat does not catch exception if the individual components are invalid meaning, Format Defined: yyyy-mm-dd input: 201-0-12 No exception will be thrown.This case should have been handled. But with the regex as suggested by Sok Pomaranczowy and Baby will take care of this particular case.

1. @Component auto detects and configures the beans using classpath scanning whereas @Bean explicitly declares a single bean, rather than letting Spring do it automatically.
2. @Component does not decouple the declaration of the bean from the class definition where as @Bean decouples the declaration of the bean from the class definition.
3. @Component is a class level annotation whereas @Bean is a method level annotation and name of the method serves as the bean name.
4. @Component need not to be used with the @Configuration annotation where as @Bean annotation has to be used within the class which is annotated with @Configuration.
5. We cannot create a bean of a class using @Component, if the class is outside spring container whereas we can create a bean of a class using @Bean even if the class is present outside the spring container.
6. @Component has different specializations like @Controller, @Repository and @Service whereas @Bean has no specializations.

Check the "tsconfig.json" file for compilation options "include" and "exclude". If it does not exist, just add them by informing your root directory.

// tsconfig.json
{
  "compilerOptions": {
  ...
  "include": [
    "src", 
  ],
  "exclude": [
    "node_modules", 
  ]
}

I solved my silly problem just by removing the extension statement "*.spec.ts" from the "exclude", because when including the "import" in these files, there were always problems.

Another solution could be:

$("#comedyclubs").next()

Your JavaScript is correct. Your button has type="submit" which is causing the page to refresh.

You need to write() the read() data into the new file:

ssize_t nrd;
int fd;
int fd1;

fd = open(aa[1], O_RDONLY);
fd1 = open(aa[2], O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
while (nrd = read(fd,buffer,50)) {
    write(fd1,buffer,nrd);
}

close(fd);
close(fd1);

Update: added the proper opens...

Btw, the O_CREAT can be OR'd (O_CREAT | O_WRONLY). You are actually opening too many file handles. Just do the open once.

What Works:

string relativePath = "..\\bling.txt";
string baseDirectory = "C:\\blah\\";
string absolutePath = Path.GetFullPath(baseDirectory + relativePath);

(result: absolutePath="C:\bling.txt")

What doesn't work

string relativePath = "..\\bling.txt";
Uri baseAbsoluteUri = new Uri("C:\\blah\\");
string absolutePath = new Uri(baseAbsoluteUri, relativePath).AbsolutePath;

(result: absolutePath="C:/blah/bling.txt")

This solution is similar to walid2mi (thank you for inspiration), but allows the standard console input by the Read-Host cmdlet.

pros:

• can be run like standard .cmd file
• only one file for batch and powershell script
• powershell script may be multi-line (easy to read script)
• allows the standard console input (use the Read-Host cmdlet by standard way)

cons:

• requires powershell version 2.0+

Commented and runable example of batch-ps-script.cmd:

<# : Begin batch (batch script is in commentary of powershell v2.0+)
@echo off
: Use local variables
setlocal
: Change current directory to script location - useful for including .ps1 files
cd %~dp0
: Invoke this file as powershell expression
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
: Restore environment variables present before setlocal and restore current directory
endlocal
: End batch - go to end of file
goto:eof
#>
# here start your powershell script

# example: include another .ps1 scripts (commented, for quick copy-paste and test run)
#. ".\anotherScript.ps1"

# example: standard input from console
$variableInput = Read-Host "Continue? [Y/N]"
if ($variableInput -ne "Y") {
    Write-Host "Exit script..."
    break
}

# example: call standard powershell command
Get-Item .

Snippet for .cmd file:

<# : batch script
@echo off
setlocal
cd %~dp0
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
endlocal
goto:eof
#>
# here write your powershell commands...

Yes it makes sense to use requireJS with Angular, I spent several days to test several technical solutions.

I made an Angular Seed with RequireJS on Server Side. Very simple one. I use SHIM notation for no AMD module and not AMD because I think it's very difficult to deal with two different Dependency injection system.

I use grunt and r.js to concatenate js files on server depends on the SHIM configuration (dependency) file. So I refer only one js file in my app.

For more information go on my github Angular Seed : https://github.com/matohawk/angular-seed-requirejs

My take on it...obviously, you've got to do something with the data you read in. If it involves writing it to the sheet, that'll be deadly slow with a normal For Loop. I came up with the following based upon a rehash of some of the items there, plus some help from the Chip Pearson website.

Reading in the text file (assuming you don't know the length of the range it will create, so only the startingCell is given):

Public Sub ReadInPlainText(startCell As Range, Optional textfilename As Variant)

   If IsMissing(textfilename) Then textfilename = Application.GetOpenFilename("All Files (*.*), *.*", , "Select Text File to Read")
   If textfilename = "" Then Exit Sub

   Dim filelength As Long
   Dim filenumber As Integer
   filenumber = FreeFile
   filelength = filelen(textfilename)
   Dim text As String
   Dim textlines As Variant

   Open textfilename For Binary Access Read As filenumber

   text = Space(filelength)
   Get #filenumber, , text

   'split the file with vbcrlf
   textlines = Split(text, vbCrLf) 

   'output to range
   Dim outputRange As Range
   Set outputRange = startCell
   Set outputRange = outputRange.Resize(UBound(textlines), 1)
   outputRange.Value = Application.Transpose(textlines)

   Close filenumber
 End Sub

Conversely, if you need to write out a range to a text file, this does it quickly in one print statement (note: the file 'Open' type here is in text mode, not binary..unlike the read routine above).

Public Sub WriteRangeAsPlainText(ExportRange As Range, Optional textfilename As Variant)
   If IsMissing(textfilename) Then textfilename = Application.GetSaveAsFilename(FileFilter:="Text Files (*.txt), *.txt")
   If textfilename = "" Then Exit Sub

   Dim filenumber As Integer
   filenumber = FreeFile
   Open textfilename For Output As filenumber

   Dim textlines() As Variant, outputvar As Variant

   textlines = Application.Transpose(ExportRange.Value)
   outputvar = Join(textlines, vbCrLf)
   Print #filenumber, outputvar
   Close filenumber
End Sub

py -m pip install numpy

Worked for me!

the error means that there is no .xib file with "JRProvidersController" name. recheck whether JRProvidersController.xib exists.

you will load .xib file with

controller = [[JRProvidersController alloc] initWithNibName:@"JRProvidersController" bundle:nil];

You can just check if the variable has a value or not. Meaning,

if( myVariable ) {
//mayVariable is not :
//null
//undefined
//NaN
//empty string ("")
//0
//false

}

If you do not know whether a variable exists (that means, if it was declared) you should check with the typeof operator. e.g.

if( typeof myVariable !== 'undefined' ) {
    // myVariable will get resolved and it is defined
}

In my case the problem occurred due to closing my PC while visual studio were remain open, so in result csproj.user file saved empty. Thankfully i have already backup, so i just copied all xml from csproj.user and paste in my affected project csproj.user file ,so it worked perfectly.

This file just contain building device info and some more.

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

select column_X, ... from my_table
where ('magic', column_X ) in (
        ('magic', 1),
        ('magic', 2),
        ('magic', 3),
        ('magic', 4),
             ...
        ('magic', 99999)
    ) ...

If the problem lies client side, this could be one of the causes of the error.

On clients TortoiseSVN saves client credentials under

Tortoise settings / saved data / authentication data.

I got the same error trying to commit my files, but my credentials were changed. Clearing this cache here will give you a popup on next commit attempt for re-entering your correct credentials.

I find this approach useful:

Create click event:

$( button ).on('click', function(e) {
    let id = e.node.data.id;

    $('#myModal').modal('show', {id: id});
});

Create show.bs.modal event:

$('#myModal').on('show.bs.modal', function (e) {

     // access parsed information through relatedTarget
     console.log(e.relatedTarget.id);

});

Extra:

Make your logic inside show.bs.modal to check whether the properties are parsed, like for instance as this: id: ( e.relatedTarget.hasOwnProperty( 'id' ) ? e.relatedTarget.id : null )

Is it proper to "reach into" an object and use its dict property?

In general, I would say "no". However Namespace has struck me as over-engineered, possibly from when classes couldn't inherit from built-in types.

On the other hand, Namespace does present a task-oriented approach to argparse, and I can't think of a situation that would call for grabbing the __dict__, but the limits of my imagination are not the same as yours.

Your code is just fine. The reason you're getting a black screen is because there's nothing on your second view controller.

Try something like:

secondViewController.view.backgroundColor = UIColor.redColor();

Now the view controller it shows should be red.

To actually do something with secondViewController, create a subclass of UIViewController and instead of

let secondViewController:UIViewController = UIViewController()

create an instance of your second view controller:

//If using code
let secondViewController = MyCustomViewController.alloc()

//If using storyboard, assuming you have a view controller with storyboard ID "MyCustomViewController"
let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("MyCustomViewController") as UIViewController

// get image from upload-image page 
public function postUplodeImage(Request $request)
{
    $this->validate($request, [
  // check validtion for image or file
        'uplode_image_file' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',
    ]);
// rename image name or file name 

    $getimageName = time().'.'.$request->uplode_image_file->getClientOriginalExtension();
    $request->uplode_image_file->move(public_path('images'), $getimageName);
    return back()
        ->with('success','images Has been You uploaded successfully.')
        ->with('image',$getimageName);
}

The simplest way

FILE=$1
[ ! -e "${FILE}" ] && echo "does not exist" || echo "exists"

In my case changing the ~/.zshenv did not work. I had to make the changes inside ~/.zshrc.

I just added:

# Include rbenv for ZSH
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

at the top of ~/.zshrc, restarted the shell and logged out.

Check if it worked:

?  ~ rbenv install 2.4.0
?  ~ rbenv global 2.4.0
?  ~ rbenv global
2.4.0
?  ~ ruby -v

If your Windows 7 machine is a member of an AD, or if you have UAC enabled, or if security policies are in effect, telnet more often than not must be run as an admin. The easiest way to do this is as follows

1. Create a shortcut that calls cmd.exe

2. Go to the shortcut's properties

3. Click on the Advanced button

4. Check the "Run as an administrator" checkbox

   After these steps you're all set and telnet should work now.

This just happen to me because in the php.ini the date.timezone was not set!

;date.timezone=Europe/Berlin

Using the php date() function triggered that warning.

Here's the easiest way, as in snapshot, download the required file and install.

In Microsoft SQL Server (T-SQL) this can be done as follows

--beginning of year
select '01/01/' + LTRIM(STR(YEAR(CURRENT_TIMESTAMP)))

--end of year
select '12/31/' + LTRIM(STR(YEAR(CURRENT_TIMESTAMP)))

CURRENT_TIMESTAMP - returns the sql server date at the time of execution of the query.

YEAR - gets the year part of the current time stamp.

STR , LTRIM - these two functions are applied so that we can convert this into a varchar that can be concatinated with our desired prefix (in this case it's either first date of the year or the last date of the year). For whatever reason the result generated by the YEAR function has prefixing spaces. To fix them we use the LTRIM function which is left trim.

I like the backwards iterator at the end of Yakk - Adam Nevraumont's answer, but it seemed complicated for what I needed, so I wrote this:

template <class T>
class backwards {
    T& _obj;
public:
    backwards(T &obj) : _obj(obj) {}
    auto begin() {return _obj.rbegin();}
    auto end() {return _obj.rend();}
};

I'm able to take a normal iterator like this:

for (auto &elem : vec) {
    // ... my useful code
}

and change it to this to iterate in reverse:

for (auto &elem : backwards(vec)) {
    // ... my useful code
}

we can find upper case letter by using regular expression as well

private static void findUppercaseFirstLetterInString(String content) {
    Matcher m = Pattern
            .compile("([a-z])([a-z]*)", Pattern.CASE_INSENSITIVE).matcher(
                    content);
    System.out.println("Given input string : " + content);
    while (m.find()) {
        if (m.group(1).equals(m.group(1).toUpperCase())) {
            System.out.println("First Letter Upper case match found :"
                    + m.group());
        }
    }
}

I always try to follow the developers advice, since they are usually the ones that now how it would affect your system. Theoretically this should be the safest way:

Install the Anaconda-Clean package from Anaconda Prompt (terminal on Linux or macOS):

conda install anaconda-clean

In the same window, run one of these commands:

1. Remove all Anaconda-related files and directories with a confirmation prompt before deleting each one:

anaconda-clean

2. Remove all Anaconda-related files and directories without being prompted to delete each one:

anaconda-clean --yes

Anaconda-Clean creates a backup of all files and directories that might be removed in a folder named .anaconda_backup in your home directory. Also note that Anaconda-Clean leaves your data files in the AnacondaProjects directory untouched.

All versions of .Net:

if (String.IsNullOrEmpty(strSearch) || strSearch.Trim().Length == 0)

.Net 4.0 or later:

if (String.IsNullOrWhitespace(strSearch))

One way to give preference to specific rows is to add a large number to their priority. You can do this with a CASE statement:

  select id, name, priority
    from mytable
order by priority + CASE WHEN name='core' THEN 1000 ELSE 0 END desc

In C++ the C-style initializers were replaced by constructors which by compile time can ensure that only valid initializations are performed (i.e. after initialization the object members are consistent).

It is a good practice, but sometimes a pre-initialization is handy, like in your example. OOP solves this by abstract classes or creational design patterns.

In my opinion, using this secure way kills the simplicity and sometimes the security trade-off might be too expensive, since simple code does not need sophisticated design to stay maintainable.

As an alternative solution, I suggest to define macros using lambdas to simplify the initialization to look almost like C-style:

struct address {
  int street_no;
  const char *street_name;
  const char *city;
  const char *prov;
  const char *postal_code;
};
#define ADDRESS_OPEN [] { address _={};
#define ADDRESS_CLOSE ; return _; }()
#define ADDRESS(x) ADDRESS_OPEN x ADDRESS_CLOSE

The ADDRESS macro expands to

[] { address _={}; /* definition... */ ; return _; }()

which creates and calls the lambda. Macro parameters are also comma separated, so you need to put the initializer into brackets and call like

address temp_address = ADDRESS(( _.city = "Hamilton", _.prov = "Ontario" ));

You could also write generalized macro initializer

#define INIT_OPEN(type) [] { type _={};
#define INIT_CLOSE ; return _; }()
#define INIT(type,x) INIT_OPEN(type) x INIT_CLOSE

but then the call is slightly less beautiful

address temp_address = INIT(address,( _.city = "Hamilton", _.prov = "Ontario" ));

however you can define the ADDRESS macro using general INIT macro easily

#define ADDRESS(x) INIT(address,x)

This seems a little more elegant

Linked to, but not explicitly mentioned here, is exactly when __all__ is used. It is a list of strings defining what symbols in a module will be exported when from <module> import * is used on the module.

For example, the following code in a foo.py explicitly exports the symbols bar and baz:

__all__ = ['bar', 'baz']

waz = 5
bar = 10
def baz(): return 'baz'

These symbols can then be imported like so:

from foo import *

print(bar)
print(baz)

# The following will trigger an exception, as "waz" is not exported by the module
print(waz)

If the __all__ above is commented out, this code will then execute to completion, as the default behaviour of import * is to import all symbols that do not begin with an underscore, from the given namespace.

Reference: https://docs.python.org/tutorial/modules.html#importing-from-a-package

NOTE: __all__ affects the from <module> import * behavior only. Members that are not mentioned in __all__ are still accessible from outside the module and can be imported with from <module> import <member>.

I find the simple solution

pylab.ticklabel_format(axis='y',style='sci',scilimits=(1,4))

I faced a similar problem passing complex strings as a POST parameter. My strings can contain Asian characters, spaces, quotes and all sorts of special characters. The solution I eventually found was to convert my string into the matching series of unicodes, e.g. "Hu0040Hu0020Hu03f5...." using [NSString stringWithFormat:@"Hu%04x",[string characterAtIndex:i]] to get the Unicode from each character in the original string. The same can be done in Java.

This string can be safely passed as a POST parameter.

On the server side (PHP), I change all the "H" to "\" and I pass the resulting string to json_decode. Final step is to escape single quotes before storing the string into MySQL.

This way I can store any UTF8 string on my server.

For jackson 2.x

@JsonInclude(JsonInclude.Include.NON_NULL)

just before the field.

When you define a layout and view on XML, you can specify the layout width and height of a view to either be wrap content, or fill parent. Taking up half of the area is a bit harder, but if you had something you wanted on the other half you could do something like the following.

   <LinearLayout android:layout_width="fill_parent"
                android:layout_height="fill_parent">
        <ImageView android:layout_height="fill_parent"
                 android:layout_width="0dp"
                 android:layout_weight="1"/>
        <ImageView android:layout_height="fill_parent"
                 android:layout_width="0dp"
                 android:layout_weight="1"/>
   </LinearLayout>

Giving two things the same weight means that they will stretch to take up the same proportion of the screen. For more info on layouts, see the dev docs.

Example java code:

        //DATA//
        //get from: https://console.aws.amazon.com/iam/home?#/security_credentials -> Access keys (access key ID and secret access key) -> Generate key if not exists
        String accessKey;
        String secretKey;
        Regions region = Regions.AP_SOUTH_1; //get from "https://ap-south-1.console.aws.amazon.com/lambda/" > your function > ARN at top right
        
        //CODE//
        AWSLambda awsLambda = AWSLambdaClientBuilder.standard()
                .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(accessKey, secretKey)))
                .withRegion(region)
                .build();

        List<FunctionConfiguration> functionList= awsLambda.listFunctions().getFunctions();
        for (FunctionConfiguration functConfig : functionList) {
           System.out.println("FunctionName="+functConfig.getFunctionName());
        }

The profile choices need to be setup as a ManyToManyField for this to work correctly.

So... your model should be like this:

class Choices(models.Model):
  description = models.CharField(max_length=300)

class Profile(models.Model):
  user = models.ForeignKey(User, blank=True, unique=True, verbose_name='user')
  choices = models.ManyToManyField(Choices)

Then, sync the database and load up Choices with the various options you want available.

Now, the ModelForm will build itself...

class ProfileForm(forms.ModelForm):
  Meta:
    model = Profile
    exclude = ['user']

And finally, the view:

if request.method=='POST':
  form = ProfileForm(request.POST)
  if form.is_valid():
    profile = form.save(commit=False)
    profile.user = request.user
    profile.save()
else:
  form = ProfileForm()

return render_to_response(template_name, {"profile_form": form}, context_instance=RequestContext(request))

It should be mentioned that you could setup a profile in a couple different ways, including inheritance. That said, this should work for you as well.

Good luck.

This is based off of "default locale"'s answer but it will remove invalid column names prior to setting ordinal. This is because if you accidentally send an invalid column name then it would fail and if you put a check to prevent it from failing then the index would be wrong since it would skip indices wherever an invalid column name was passed in.

public static class DataTableExtensions
{
    /// <summary>
    /// SetOrdinal of DataTable columns based on the index of the columnNames array. Removes invalid column names first.
    /// </summary>
    /// <param name="table"></param>
    /// <param name="columnNames"></param>
    /// <remarks> http://stackoverflow.com/questions/3757997/how-to-change-datatable-colums-order</remarks>
    public static void SetColumnsOrder(this DataTable dtbl, params String[] columnNames)
    {
        List<string> listColNames = columnNames.ToList();

        //Remove invalid column names.
        foreach (string colName in columnNames)
        {
            if (!dtbl.Columns.Contains(colName))
            {
                listColNames.Remove(colName);
            }
        }

        foreach (string colName in listColNames)
        {
            dtbl.Columns[colName].SetOrdinal(listColNames.IndexOf(colName));
        }
}

Try swich fetchType from LAZY to EAGER

Apple OSX Folder Actions allow you to automate tasks based on actions taken on a folder.

This is really a long thread, and probably because the answers albeit correct are not resolving the fundamental question. I came across this site: Version & Build Numbers that provided a clear overview of what is what in the Microsoft Windows world.

Since my interest is to know which exact windows OS I am dealing with, I left aside the entire version rainbow and instead focused on the BuildNumber. The build number may be attained either by:

([Environment]::OSVersion.Version).Build

or by:

(Get-CimInstance Win32_OperatingSystem).buildNumber

the choice is yours which ever way you prefer it. So from there I could do something along the lines of:

    switch ((Get-CimInstance Win32_OperatingSystem).BuildNumber) 
{
    6001 {$OS = "W2K8"}
    7600 {$OS = "W2K8R2"}
    7601 {$OS = "W2K8R2SP1"}    
    9200 {$OS = "W2K12"}
    9600 {$OS = "W2K12R2"}
    14393 {$OS = "W2K16v1607"}
    16229 {$OS = "W2K16v1709"}
    default { $OS = "Not Listed"}

}
Write-Host "Server system: $OS" -foregroundcolor Green

Note: As you can see I used the above just for server systems, however it could easily be applied to workstations or even cleverly extended to support both... but I'll leave that to you.

Enjoy, & have fun!

android:listSelector="@android:color/transparent" 
android:cacheColorHint="@android:color/transparent"
/>

This is very possible. I mocked up 3 pages which should give you a proof of concept:

.aspx page:

<form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:TextBox TextMode="password" ID="TextBox2" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </div>
</form>

code behind:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    For Each s As String In Request.Form.AllKeys
        Response.Write(s & ": " & Request.Form(s) & "<br />")
    Next
End Sub

Separate HTML page:

<form action="http://localhost/MyTestApp/Default.aspx" method="post">
    <input name="TextBox1" type="text" value="" id="TextBox1" />
    <input name="TextBox2" type="password" id="TextBox2" />
    <input type="submit" name="Button1" value="Button" id="Button1" />
</form>

...and it regurgitates the form values as expected. If this isn't working, as others suggested, use a traffic analysis tool (fiddler, ethereal), because something probably isn't going where you're expecting.

You're probably talking about unobtrusive Javascript, which would look like this:

<a href="#" id="someLink">link</a>

with the logic in a central javascript file looking something like this:

$('#someLink').click(function(){
    popup('/map/', 300, 300, 'map'); 
    return false;
});

The advantages are

• behaviour (Javascript) is separated from presentation (HTML)
• no mixing of languages
• you're using a javascript framework like jQuery that can handle most cross-browser issues for you
• You can add behaviour to a lot of HTML elements at once without code duplication

You may try the following:

SELECT CONVERT(VARCHAR(10),yourdate,101);

or this:

select cast(floor(cast(urdate as float)) as datetime);

Turns out that I had this problem and it was because I used "tabs" to indent lines instead of spaces. Just posting, in case it helps anyone.

select *
from user
left join edge
on user.userid = edge.tailuser
and edge.headuser = 5043

Unique Approach

(Will work for Dialog, Fragment, Even Util class etc...)

ApplicationContext.getInstance().toast("I am toast");

Add below code in Application class accordingly.

public class ApplicationContext extends Application {

private static ApplicationContext instance;

@Override
public void onCreate() {
    super.onCreate();
    instance = this;
}

public static void toast(String message) {
    Toast.makeText(getContext(), message, Toast.LENGTH_SHORT).show();
}
}

A .java file is the code file. A .class file is the compiled file.

It's not exactly "conversion" - it's compilation. Suppose your file was called "herb.java", you would write (in the command prompt):

 javac herb.java

It will create a herb.class file in the current folder.

It is "executable" only if it contains a static void main(String[]) method inside it. If it does, you can execute it by running (again, command prompt:)

 java herb
