Even if you do not have the pid, you can trigger 'wait;' after triggering all background processes. For. eg. in commandfile.sh-

bteq < input_file1.sql > output_file1.sql &
bteq < input_file2.sql > output_file2.sql &
bteq < input_file3.sql > output_file3.sql &
wait

Then when this is triggered, as -

subprocess.call(['sh', 'commandfile.sh'])
print('all background processes done.')

This will be printed only after all the background processes are done.

If you want to write a graphical UI in bash, zenity is the way to go. This is what you can do with it:

Application Options:

Combining these widgets you can create pretty usable GUIs. Of course, it's not as flexible as a toolkit integrated into a programming language, but in some cases it's really useful.

<?php if ($foo) { ?>
    <div class="mydiv">Condition is true</div>
<?php } else { ?>
    <div class="myotherdiv">Condition is false</div>
<?php } ?>

There are two things you can do first undo merge by command

git merge --abort

or

you can go to your previous commit state temporarily by command

git checkout 0d1d7fc32 

public  static byte[][] arrayCopy(byte[][] arr){
    if(arr!=null){
        int[][] arrCopy = new int[arr.length][] ;
        System.arraycopy(arr, 0, arrCopy, 0, arr.length);
        return arrCopy;
    }else { return new int[][]{};}
}

Set-ADUser -Identity anyUser -Replace @{extensionAttribute4="myString"}

This is also usefull

Date.prototype.addDays = function(days) {

   var dat = new Date(this.valueOf())
   dat.setDate(dat.getDate() + days);
   return dat;
}

function getDates(startDate, stopDate) {

  var dateArray = new Array();
  var currentDate = startDate;
  while (currentDate <= stopDate) {
    dateArray.push(currentDate);
    currentDate = currentDate.addDays(1);
  }
  return dateArray;
}

var dateArray = getDates(new Date(), (new Date().addDays(7)));

for (i = 0; i < dateArray.length; i ++ ) {
  //  alert (dateArray[i]);

    date=('0'+dateArray[i].getDate()).slice(-2);
    month=('0' +(dateArray[i].getMonth()+1)).slice(-2);
    year=dateArray[i].getFullYear();
    alert(date+"-"+month+"-"+year );
}

Where on earth did you find this syntax? Java Enums are very simple, you just specify the values.

public enum Gender {
   MALE,
   FEMALE
}

If you want them to be more complex, you can add values to them like this.

public enum Gender {
    MALE("Male", 0),
    FEMALE("Female", 1);

    private String stringValue;
    private int intValue;
    private Gender(String toString, int value) {
        stringValue = toString;
        intValue = value;
    }

    @Override
    public String toString() {
        return stringValue;
    }
}

Then to use the enum, you would do something like this:

Gender me = Gender.MALE

HttpClient webClient = new HttpClient();
Uri uri = new Uri("your url");
HttpResponseMessage response = await webClient.GetAsync(uri)
var jsonString = await response.Content.ReadAsStringAsync();
var objData = JsonConvert.DeserializeObject<List<CategoryModel>>(jsonString);

In Java, you really want to use Integer.toString to convert an integer to its corresponding String value. If you are dealing with just the digits 0-9, then you could use something like this:

private static final char[] DIGITS =
    {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};

private static char getDigit(int digitValue) {
   assertInRange(digitValue, 0, 9);
   return DIGITS[digitValue];
}

Or, equivalently:

private static int ASCII_ZERO = 0x30;

private static char getDigit(int digitValue) {
  assertInRange(digitValue, 0, 9);
  return ((char) (digitValue + ASCII_ZERO));
}

According to How to convert Strings to and from UTF8 byte arrays in Java:

String s = "some text here";
byte[] b = s.getBytes("UTF-8");
System.out.println(b.length);

You can apply the .toUpperCase() directly on String variables or as an attribute to text fields. Ex: -

String str;
TextView txt;

str.toUpperCase();// will change it to all upper case OR
txt.append(str.toUpperCase());
txt.setText(str.toUpperCase());

I know this is not typical alert box, but I hope it may help someone.

There is this expansion that enables you to show notifications inside HTML page using bootstrap.

It is very easy to implement and it works fine. Here is a github page for the project including some demo images.

The information provided in this answer can lead to insecure programming practices.

The information provided here depends highly on MySQL configuration, including (but not limited to) the program version, the database client and character-encoding used.

See http://dev.mysql.com/doc/refman/5.0/en/string-literals.html

MySQL recognizes the following escape sequences.
\0     An ASCII NUL (0x00) character.
\'     A single quote (“'”) character.
\"     A double quote (“"”) character.
\b     A backspace character.
\n     A newline (linefeed) character.
\r     A carriage return character.
\t     A tab character.
\Z     ASCII 26 (Control-Z). See note following the table.
\\     A backslash (“\”) character.
\%     A “%” character. See note following the table.
\_     A “_” character. See note following the table.

So you need

select * from tablename where fields like "%string \"hi\" %";

Although as Bill Karwin notes below, using double quotes for string delimiters isn't standard SQL, so it's good practice to use single quotes. This simplifies things:

select * from tablename where fields like '%string "hi" %';

Try this:

public class abc extends Activity implements OnPreparedListener{

  /** Called when the activity is first created. */

  @Override
    public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.youtube.com/watch?v=cxLG2wtE7TM")));          


    @Override
      public void onPrepared(MediaPlayer mp) {
        // TODO Auto-generated method stub

    }
  }
}

Another reason this can happen:

The component you are using formControl in is not declared in a module that imports the ReactiveFormsModule.

So check the module that declares the component that throws this error.

in my case, the SFTP server will reject your SSH connection.

In the Params I have added model.Email and model.Password, work for me well. Thanks for the question. I tried the same thing in headers did not work. But it worked on Body with form-data and x-www-form-urlencoded.

I just needed to make artisan executable.

chmod +x artisan

...and it works without the php prefix then.

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

Prevent browser cache is not a good idea depending on the case. Looking for a solution I found solutions like this:

<link rel="stylesheet" type="text/css" href="meu.css?v=<?=filemtime($file);?>">

the problem here is that if the file is overwritten during an update on the server, which is my scenario, the cache is ignored because timestamp is modified even the content of the file is the same.

I use this solution to force browser to download assets only if its content is modified:

<link rel="stylesheet" type="text/css" href="meu.css?v=<?=hash_file('md5', $file);?>">

Question : What is the best practice of returning/storing variables of multiple threads? A global hash table?

This totally depends on what you want to return and how you would use it? If you want to return only status of the thread (say whether the thread completed what it intended to do) then just use pthread_exit or use a return statement to return the value from the thread function.

But, if you want some more information which will be used for further processing then you can use global data structure. But, in that case you need to handle concurrency issues by using appropriate synchronization primitives. Or you can allocate some dynamic memory (preferrably for the structure in which you want to store the data) and send it via pthread_exit and once the thread joins, you update it in another global structure. In this way only the one main thread will update the global structure and concurrency issues are resolved. But, you need to make sure to free all the memory allocated by different threads.

Using these libraries:

• gson-2.8.5.jar
• json-20180813.jar

Using this code:

List<Object[]> testNovedads = crudService.createNativeQuery(
                "SELECT cantidad, id FROM NOVEDADES GROUP BY id ");

        Gson gson = new Gson();
        String json = gson.toJson(new TestNovedad());
        JSONObject jsonObject = new JSONObject(json);
        Collection<TestNovedad> novedads = new ArrayList<>();
        for (Object[] object : testNovedads) {
            Iterator<String> iterator = jsonObject.keys();
            int pos = 0;
            for (Iterator i = iterator; i.hasNext();) {
                jsonObject.put((String) i.next(), object[pos++]);
            }
            novedads.add(gson.fromJson(jsonObject.toString(), TestNovedad.class));
        }
        for (TestNovedad testNovedad : novedads) {
            System.out.println(testNovedad.toString());
        }

/**

import java.io.Serializable;

    }

    public void setCantidad(int cantidad) {
        this.cantidad = cantidad;

}

For anyone else arriving at this question:

I was performing the most simple jQuery, trying to hide an element:

('#fileselection').hide();

and I was getting the same type of error, "Uncaught TypeError: Object #fileselection has no method 'hide'

Of course, now it is obvious, but I just left off the jQuery indicator '$'. The code should have been:

$('#fileselection').hide();

This fixes the no-brainer problem. I hope this helps someone save a few minutes debugging!

Because a 32-bit floating-point number - such as 1.024 - is not 1.024. In a computer, 1.024 is an interval: from (1.024-e) to (1.024+e), where "e" represents an error. Some people fail to realize this and also believe that * in a*a stands for multiplication of arbitrary-precision numbers without there being any errors attached to those numbers. The reason why some people fail to realize this is perhaps the math computations they exercised in elementary schools: working only with ideal numbers without errors attached, and believing that it is OK to simply ignore "e" while performing multiplication. They do not see the "e" implicit in "float a=1.2", "a*a*a" and similar C codes.

Should majority of programmers recognize (and be able to execute on) the idea that C expression a*a*a*a*a*a is not actually working with ideal numbers, the GCC compiler would then be FREE to optimize "a*a*a*a*a*a" into say "t=(a*a); t*t*t" which requires a smaller number of multiplications. But unfortunately, the GCC compiler does not know whether the programmer writing the code thinks that "a" is a number with or without an error. And so GCC will only do what the source code looks like - because that is what GCC sees with its "naked eye".

... once you know what kind of programmer you are, you can use the "-ffast-math" switch to tell GCC that "Hey, GCC, I know what I am doing!". This will allow GCC to convert a*a*a*a*a*a into a different piece of text - it looks different from a*a*a*a*a*a - but still computes a number within the error interval of a*a*a*a*a*a. This is OK, since you already know you are working with intervals, not ideal numbers.

Here is a one line code that cleans up the PATH

• It does not disturb the order of the PATH, just removes duplicates
• Treats : and empth PATH gracefully
• No special characters used, so does not require escape

• Uses /bin/awk so it works even when PATH is broken

  export PATH="$(echo "$PATH" |/bin/awk 'BEGIN{RS=":";}
  {sub(sprintf("%c$",10),"");if(A[$0]){}else{A[$0]=1;
  printf(((NR==1)?"":":")$0)}}')";
  

linq many ways to implement single simple query on collections, just we write joins in sql, a filter can be applied first or last depending on the need and necessity.

Here is an example where we can find an element with a id in a collection. To add more on this, methods First, FirstOrDefault, would ideally return same when a collection has at least one record. If, however, a collection is okay to be empty. then First will return an exception but FirstOrDefault will return null or default. For instance, int will return 0. Thus usage of such is although said to be personal preference, but its better to use FirstOrDefault to avoid exception handling.

If you're using Radiant CMS, simply add

require 'thread'

If the requirement is to copy all files in "\Publish\Appfolder" into the parent "\Publish\" folder (inclusive of any subfolders, following works for me) The switch '/s' allows copying of all subfolders, recursively.

xcopy src\main\Publish\Appfolder\*.* /s src\main\Publish\

At first see this question to see how you can find if a link has a jQuery handler assigned to it.

Next use:

$("a").attr("onclick")

to see if there is a javascript event assigned to it.

If any of the above is true, then call the click method. If not, get the link:

$("a").attr("href")

and follow it.

I am afraid I don't know what to do if addEventListener is used to add an event handler. If you are in charge of the full page source, use only jQuery event handlers.

This worked for me. It loops though the classes and checks to see if they are derrived from myInterface

 foreach (Type mytype in System.Reflection.Assembly.GetExecutingAssembly().GetTypes()
                 .Where(mytype => mytype .GetInterfaces().Contains(typeof(myInterface)))) {
    //do stuff
 }

Getting this error, I changed the

c/C++ > Code Generation > Runtime Library to Multi-threaded library (DLL) /MD

Note: all components of the project must have the same definition in c/C++ > Code Generation > Runtime Library. Either DLL or not DLL, but identical.

You are calling the one.start() method in the run method of your Thread. But the run method will only be called when a thread is already started. Do this instead:

one = new Thread() {
    public void run() {
        try {
            System.out.println("Does it work?");

            Thread.sleep(1000);

            System.out.println("Nope, it doesnt...again.");
        } catch(InterruptedException v) {
            System.out.println(v);
        }
    }  
};

one.start();

// get the data table
DataTable dt = ...;

// generate the data you want to insert
DataRow toInsert = dt.NewRow();

// insert in the desired place
dt.Rows.InsertAt(toInsert, index);

Change the URL (i.e. http://www.techlila.com) as per your need.

This is the correct URL, I'm getting right results.

EDIT (May 2017): as of v2.9 you can make a graph API call where ID is the URL and select the 'engagement' field, below is a link with the example from the graph explorer.

https://developers.facebook.com/tools/explorer/?method=GET&path=%3Fid%3Dhttp%3A%2F%2Fcomunidade.edp.pt%26fields%3Dengagement&version=v2.9

something like this:

List<string> test1 = new List<string> { "@bob.com", "@tom.com" };
List<string> test2 = new List<string> { "[email protected]", "[email protected]" };

var res = test2.Where(f => test1.Count(z => f.Contains(z)) == 0)

Live example: here

Try this:-

private String getWhoozitYs(){
    StringBuffer sb = new StringBuffer();
    boolean stop = generator.nextBoolean();
    if(stop)
    {
        sb.append("y");
        getWhoozitYs();
    }
    return sb.toString();
}

You can try a list comp

>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

Another way is by using filter

>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

The probelm with your first code block was that you were opening the file as 'r' even though you wanted to write to it using 'w'

with open('/Users/your/path/foo','w') as data:
    data.write(str(dictionary))

Don't use list as a variable name. It's a built in that you are masking.

To insert, use the insert function of lists.

l = ['hello','world']
l.insert(0, 'foo')
print l
['foo', 'hello', 'world']

In regards to your error and what's missing in your code. m is a name which is not defined for getmd5() function.

No offence, I know you are a beginner, but your code is all over the place. Let's look at your issues one by one :)

First, you are not using hashlib.md5.hexdigest() method correctly. Please refer explanation on hashlib functions in Python Doc Library. The correct way to return MD5 for provided string is to do something like this:

>>> import hashlib
>>> hashlib.md5("filename.exe").hexdigest()
'2a53375ff139d9837e93a38a279d63e5'

However, you have a bigger problem here. You are calculating MD5 on a file name string, where in reality MD5 is calculated based on file contents. You will need to basically read file contents and pipe it though MD5. My next example is not very efficient, but something like this:

>>> import hashlib
>>> hashlib.md5(open('filename.exe','rb').read()).hexdigest()
'd41d8cd98f00b204e9800998ecf8427e'

As you can clearly see second MD5 hash is totally different from the first one. The reason for that is that we are pushing contents of the file through, not just file name.

A simple solution could be something like that:

# Import hashlib library (md5 method is part of it)
import hashlib

# File to check
file_name = 'filename.exe'

# Correct original md5 goes here
original_md5 = '5d41402abc4b2a76b9719d911017c592'  

# Open,close, read file and calculate MD5 on its contents 
with open(file_name) as file_to_check:
    # read contents of the file
    data = file_to_check.read()    
    # pipe contents of the file through
    md5_returned = hashlib.md5(data).hexdigest()

# Finally compare original MD5 with freshly calculated
if original_md5 == md5_returned:
    print "MD5 verified."
else:
    print "MD5 verification failed!."

Please look at the post Python: Generating a MD5 checksum of a file. It explains in detail a couple of ways how it can be achieved efficiently.

Best of luck.

NSString * result = [[array valueForKey:@"description"] componentsJoinedByString:@""];

if you use mvvm and your itemssource is located in your vm. just call INotifyPropertyChanged for your collection property when you want to refresh.

OnPropertyChanged("YourCollectionProperty");

iText has more than one way of doing this. The PdfStamper class is one option. But I find the easiest method is to create a new PDF document then import individual pages from the existing document into the new PDF.

// Create output PDF
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();

// Load existing PDF
PdfReader reader = new PdfReader(templateInputStream);
PdfImportedPage page = writer.getImportedPage(reader, 1); 

// Copy first page of existing PDF into output PDF
document.newPage();
cb.addTemplate(page, 0, 0);

// Add your new data / text here
// for example...
document.add(new Paragraph("my timestamp")); 

document.close();

This will read in a PDF from templateInputStream and write it out to outputStream. These might be file streams or memory streams or whatever suits your application.

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

The only way I found is check if navigator.userAgent contains iPhone or iPad word

if (navigator.userAgent.toLowerCase().match(/(ipad|iphone)/)) {
    //is safari
}

What I found out is that MS Access will reject --Not Like "BB*"-- if not enclosed in PARENTHESES, unlike --Like "BB*"-- which is ok without parentheses.

I tested these on MS Access 2010 and are all valid:

1. Like "BB"

2. (Like "BB")

3. (Not Like "BB")

Added some supplemental code to the accepted answer. It improves upon answers just using Random and allows for some password options. I also liked some of the options from the KeePass answer but did not want to include the executable in my solution.

private string RandomPassword(int length, bool includeCharacters, bool includeNumbers, bool includeUppercase, bool includeNonAlphaNumericCharacters, bool includeLookAlikes)
{
    if (length < 8 || length > 128) throw new ArgumentOutOfRangeException("length");
    if (!includeCharacters && !includeNumbers && !includeNonAlphaNumericCharacters) throw new ArgumentException("RandomPassword-Key arguments all false, no values would be returned");

    string pw = "";
    do
    {
        pw += System.Web.Security.Membership.GeneratePassword(128, 25);
        pw = RemoveCharacters(pw, includeCharacters, includeNumbers, includeUppercase, includeNonAlphaNumericCharacters, includeLookAlikes);
    } while (pw.Length < length);

    return pw.Substring(0, length);
}

private string RemoveCharacters(string passwordString, bool includeCharacters, bool includeNumbers, bool includeUppercase, bool includeNonAlphaNumericCharacters, bool includeLookAlikes)
{
    if (!includeCharacters)
    {
        var remove = new string[] { "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z" };
        foreach (string r in remove)
        {
            passwordString = passwordString.Replace(r, string.Empty);
            passwordString = passwordString.Replace(r.ToUpper(), string.Empty);
        }
    }

    if (!includeNumbers)
    {
        var remove = new string[] { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };
        foreach (string r in remove)
            passwordString = passwordString.Replace(r, string.Empty);
    }

    if (!includeUppercase)
        passwordString = passwordString.ToLower();

    if (!includeNonAlphaNumericCharacters)
    {
        var remove = new string[] { "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "-", "_", "+", "=", "{", "}", "[", "]", "|", "\\", ":", ";", "<", ">", "/", "?", "." };
        foreach (string r in remove)
            passwordString = passwordString.Replace(r, string.Empty);
    }

    if (!includeLookAlikes)
    {
        var remove = new string[] { "(", ")", "0", "O", "o", "1", "i", "I", "l", "|", "!", ":", ";" };
        foreach (string r in remove)
            passwordString = passwordString.Replace(r, string.Empty);
    }

    return passwordString;
}

This was the first link when I searched for generating random passwords and the following is out of scope for the current question but might be important to consider.

• Based upon the assumption that System.Web.Security.Membership.GeneratePassword is cryptographically secure with a minimum of 20% of the characters being Non-Alphanumeric.
• Not sure if removing characters and appending strings is considered good practice in this case and provides enough entropy.
• Might want to consider implementing in some way with SecureString for secure password storage in memory.

Best ever solution ever is here.

if ((self.navigationController?.popViewController(animated: true)) == nil) {
     self.dismiss(animated: true, completion: nil)
}

Check if Pop Navigation provide nil then Dismiss Controller. It can handle Pop and Dismiss vice versa.

<EditText
    android:id="@+id/search"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search_hint"
    android:inputType="text"
    android:imeOptions="actionSend" />

You can then listen for presses on the action button by defining a TextView.OnEditorActionListener for the EditText element. In your listener, respond to the appropriate IME action ID defined in the EditorInfo class, such as IME_ACTION_SEND. For example:

EditText editText = (EditText) findViewById(R.id.search);
editText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        boolean handled = false;
        if (actionId == EditorInfo.IME_ACTION_SEND) {
            sendMessage();
            handled = true;
        }
        return handled;
    }
});

I just triggered the tests on a pull request to be re-run by clicking 'update branch' here:

Indeed, set in DOS has no option to allow for arithmetic. You could do a giant lookup table, though:

if %COUNTER%==249 set COUNTER=250
...
if %COUNTER%==3 set COUNTER=4
if %COUNTER%==2 set COUNTER=3
if %COUNTER%==1 set COUNTER=2
if %COUNTER%==0 set COUNTER=1

The server (that the POST request is sent to) needs to include the Content-Type header in its response.

Here's a list of typical headers to include, including one custom "X_ACCESS_TOKEN" header:

"X-ACCESS_TOKEN", "Access-Control-Allow-Origin", "Authorization", "Origin", "x-requested-with", "Content-Type", "Content-Range", "Content-Disposition", "Content-Description"

That's what your http server guy needs to configure for the web server that you're sending your requests to.

You may also want to ask your server guy to expose the "Content-Length" header.

He'll recognize this as a Cross-Origin Resource Sharing (CORS) request and should understand the implications of making those server configurations.

For details see:

An alternative to @inspectorG4dget answer (best answer to date 29-03-2016). I tested with 3 files of 436MB.

@inspectorG4dget solution: 162 seconds

The following solution : 125 seconds

from subprocess import Popen
filenames = ['file1.txt', 'file2.txt', 'file3.txt']
fbatch = open('batch.bat','w')
str ="type "
for f in filenames:
    str+= f + " "
fbatch.write(str + " > file4results.txt")
fbatch.close()
p = Popen("batch.bat", cwd=r"Drive:\Path\to\folder")
stdout, stderr = p.communicate()

The idea is to create a batch file and execute it, taking advantage of "old good technology". Its semi-python but works faster. Works for windows.

You can add a 1 GB swap to your instance with these commands:

sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
sudo mkswap /swapfile
sudo swapon /swapfile

To enable it by default after reboot, add this line to /etc/fstab:

/swapfile swap swap defaults 0 0

Objects are eligable for garbage collection once they go out of scope become unreachable (thanks ben!). The memory won't be freed unless the garbage collector believes you are running out of memory.

For managed resources, the garbage collector will know when this is, and you don't need to do anything.

For unmanaged resources (such as connections to databases or opened files) the garbage collector has no way of knowing how much memory they are consuming, and that is why you need to free them manually (using dispose, or much better still the using block)

If objects are not being freed, either you have plenty of memory left and there is no need, or you are maintaining a reference to them in your application, and therefore the garbage collector will not free them (in case you actually use this reference you maintained)

I'm not familiar with resolve, but I've used the others:

Recursive

Recursive is the default for non-fast-forward merges. We're all familiar with that one.

Octopus

I've used octopus when I've had several trees that needed to be merged. You see this in larger projects where many branches have had independent development and it's all ready to come together into a single head.

An octopus branch merges multiple heads in one commit as long as it can do it cleanly.

For illustration, imagine you have a project that has a master, and then three branches to merge in (call them a, b, and c).

A series of recursive merges would look like this (note that the first merge was a fast-forward, as I didn't force recursion):

However, a single octopus merge would look like this:

commit ae632e99ba0ccd0e9e06d09e8647659220d043b9
Merge: f51262e... c9ce629... aa0f25d...

Ours

Ours == I want to pull in another head, but throw away all of the changes that head introduces.

This keeps the history of a branch without any of the effects of the branch.

(Read: It is not even looked at the changes between those branches. The branches are just merged and nothing is done to the files. If you want to merge in the other branch and every time there is the question "our file version or their version" you can use git merge -X ours)

Subtree

Subtree is useful when you want to merge in another project into a subdirectory of your current project. Useful when you have a library you don't want to include as a submodule.

Add field if not exist:

CALL addFieldIfNotExists ('settings', 'multi_user', 'TINYINT(1) NOT NULL DEFAULT 1');

DROP PROCEDURE IF EXISTS addFieldIfNotExists

DROP FUNCTION IF EXISTS isFieldExisting 
$$

CREATE FUNCTION isFieldExisting (table_name_IN VARCHAR(100), field_name_IN VARCHAR(100))

RETURN (
    SELECT COUNT(COLUMN_NAME) 
    FROM INFORMATION_SCHEMA.columns 
    WHERE TABLE_SCHEMA = DATABASE() 
    AND TABLE_NAME = table_name_IN

        SET @ddl = CONCAT(@ddl, ' ', field_definition_IN);

        PREPARE stmt FROM @ddl;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;

As pointed by Larcho, starting from API level 10, you can use BitmapRegionDecoder to load specific regions from an image and with that, you can accomplish to show a large image in high resolution by allocating in memory just the needed regions. I've recently developed a lib that provides the visualisation of large images with touch gesture handling. The source code and samples are available here.

.modal {
  text-align: center;
}

@media screen and (min-width: 768px) { 
  .modal:before {
    display: inline-block;
    vertical-align: middle;
    content: " ";
    height: 100%;
  }
}

.modal-dialog {
  display: inline-block;
  text-align: left;
  vertical-align: middle;
}

And adjust a little bit .fade class to make sure it appears out of the top border of window, instead of center

you can use two different methods to delete or any query in sqlite android

first method is

public void deleteItem(Student item) {
 SQLiteDatabase db = getWritableDatabase();
 String whereClause = "id=?";
 String whereArgs[] = {item.id.toString()};
 db.delete("Items", whereClause, whereArgs);
}

second method

public void deleteAll()
{
  SQLiteDatabase db = this.getWritableDatabase();
  db.execSQL("delete from "+ TABLE_NAME);
  db.close();
}

use any method for your use case

I would suggest that the current solution is to use my package urllib2_prior_auth which solves this pretty nicely (I work on inclusion to the standard lib.

I prefer to use <limits> to check for an int until it is passed.

#include <iostream>
#include <limits> //std::numeric_limits

using std::cout, std::endl, std::cin;

int main() {
    int num;
    while(!(cin >> num)){  //check the Input format for integer the right way
        cin.clear();
        cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        cout << "Invalid input.  Reenter the number: ";
      };

    cout << "output= " << num << endl;

    return 0;
}

Another regex solution:

string.replace(/\D/g,'');  //remove the non-Numeric

Similarly, you can

string.replace(/\W/g,'');  //remove the non-alphaNumeric

In RegEX, the symbol '\' would make the letter following it a template: \w -- alphanumeric, and \W - Non-AlphaNumeric, negates when you capitalize the letter.

I saw in getwindowtext (user32) on pinvoke.net that you can place a MarshalAs statement to state that the StringBuffer is equivalent to LPSTR.

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Ansi)> _

Step #1: Wrap whatever it is you want centered on the screen in a full-screen RelativeLayout.

Step #2: Give that child view (the one, which you want centered inside the RelativeLayout) the android:layout_centerInParent="true" attribute.

It's not an NPP solution, but in a pinch, you can use this online JSON Formatter and then just paste the formatted text into NPP and then select Javascript as the language.

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

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

Here is pretty bad advise with better one to follow:

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

Good advise: There are few pretty good Angular2 datepickers:

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

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

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

I resolved the issue by double checking the "libs" directory and removing redundant jars, even though those jars were not manually added in the dependencies.

var myVar = $("#start").find('myClass').val();

needs to be

var myVar = $("#start").find('.myClass').val();

Remember the CSS selector rules require "." if selecting by class name. The absence of "." is interpreted to mean searching for <myclass></myclass>.

You config proxy settings for some network and now you connect another network. Now have to remove the proxy settings. For that use these commands:

git config --global --unset https.proxy
git config --global --unset http.proxy

Now you can push too. (If did not remove proxy configuration still you can use git commands like add , commit and etc)

This regex should do it.

\b[a-z]+-[a-z]+\b 

\b indicates a word-boundary.

You need to first change the constraint and then animate the update.
This should be in the superview.

self.nameInputConstraint.constant = 8

Swift 2

UIView.animateWithDuration(0.5) {
    self.view.layoutIfNeeded()
}

Swift 3, 4, 5

UIView.animate(withDuration: 0.5) {
    self.view.layoutIfNeeded()
}

Short answer

The Bearer authentication scheme is what you are looking for.

Long answer

Is it related to bears?

Errr... No :)

According to the Oxford Dictionaries, here's the definition of bearer:

bearer _^/'b??r?/
noun

1. A person or thing that carries or holds something.

2. A person who presents a cheque or other order to pay money.

The first definition includes the following synonyms: messenger, agent, conveyor, emissary, carrier, provider.

And here's the definition of bearer token according to the RFC 6750:

1.2. Terminology

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer authentication scheme is registered in IANA and originally defined in the RFC 6750 for the OAuth 2.0 authorization framework, but nothing stops you from using the Bearer scheme for access tokens in applications that don't use OAuth 2.0.

Stick to the standards as much as you can and don't create your own authentication schemes.

An access token must be sent in the Authorization request header using the Bearer authentication scheme:

2.1. Authorization Request Header Field

When sending the access token in the Authorization request header field defined by HTTP/1.1, the client uses the Bearer authentication scheme to transmit the access token.

For example:

GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer mF_9.B5f-4.1JqM

[...]

Clients SHOULD make authenticated requests with a bearer token using the Authorization request header field with the Bearer HTTP authorization scheme. [...]

In case of invalid or missing token, the Bearer scheme should be included in the WWW-Authenticate response header:

3. The WWW-Authenticate Response Header Field

If the protected resource request does not include authentication credentials or does not contain an access token that enables access to the protected resource, the resource server MUST include the HTTP WWW-Authenticate response header field [...].

All challenges defined by this specification MUST use the auth-scheme value Bearer. This scheme MUST be followed by one or more auth-param values. [...].

For example, in response to a protected resource request without authentication:

HTTP/1.1 401 Unauthorized
WWW-Authenticate: Bearer realm="example"

And in response to a protected resource request with an authentication attempt using an expired access token:

HTTP/1.1 401 Unauthorized
WWW-Authenticate: Bearer realm="example",
                         error="invalid_token",
                         error_description="The access token expired"

For other future users who do not want to make their controllers asynchronous, or cannot access the HttpContext, or are using dotnet core (this answer is the first I found on Google trying to do this), the following worked for me:

[HttpPut("{pathId}/{subPathId}"),
public IActionResult Put(int pathId, int subPathId, [FromBody] myViewModel viewModel)
{

    var body = new StreamReader(Request.Body);
    //The modelbinder has already read the stream and need to reset the stream index
    body.BaseStream.Seek(0, SeekOrigin.Begin); 
    var requestBody = body.ReadToEnd();
    //etc, we use this for an audit trail
}

HTML

<!DOCTYPE html>
<html>
    <head>
        <title>Center</title>        
    </head>
    <body>
        <div id="main_body">
          some text
        </div>
    </body>
</html>

CSS

body
{
   width: 100%;
   Height: 100%;
}
#main_body
{
    background: #ff3333;
    width: 200px;
    position: absolute;
}?

JS ( jQuery )

$(function(){
    var windowHeight = $(window).height();
    var windowWidth = $(window).width();
    var main = $("#main_body");    
    $("#main_body").css({ top: ((windowHeight / 2) - (main.height() / 2)) + "px",
                          left:((windowWidth / 2) - (main.width() / 2)) + "px" });
});

See example here

a solution can be having the close inside your modal

take a look at this simple example

import subprocess as s
ip=raw_input("Enter the IP/Domain name:")
if(s.call(["ping",ip])==0):
    print "your IP is alive"
else:
    print "Check ur IP"

You can use pagination with a native query. It is documented here: https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#_native_queries

"You can however use native queries for pagination by specifying the count query yourself: Example 59. Declare native count queries for pagination at the query method using @Query"

public interface UserRepository extends JpaRepository<User, Long> {

  @Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1",
    countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
    nativeQuery = true)
  Page<User> findByLastname(String lastname, Pageable pageable);
}

One liner for callstack:

One liner for callstack without all the gems's:

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace.grep_v(/\/gems\//); end

One liner for callstack without all the gems's and relative to current directory

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace.grep_v(/\/gems\//).map { |l| l.gsub(`pwd`.strip + '/', '') }; end

left click on it and you will see two options as shown in below picture

click on the first option so that you can preview your app in android studio

Based on Piotr Migdals response I want to give an alternate solution enabling the possibility for a vector of strings:

myVectorOfStrings <- c("foo", "bar")
matchExpression <- paste(myVectorOfStrings, collapse = "|")
# [1] "foo|bar"
df %>% select(matches(matchExpression))

Making use of the regex OR operator (|)

ATTENTION: If you really have a plain vector of column names (and do not need the power of RegExpression), please see the comment below this answer (since it's the cleaner solution).

In ./package.json:

"jest": {
  "setupFiles": [
    "<rootDir>/jest/setEnvVars.js"
  ]
}

In ./jest/setEnvVars.js:

process.env.SOME_VAR = 'value';

Define the following function (not mine, not sure where I found it long ago):

private static String convertStreamToString(InputStream is) {

BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
    while ((line = reader.readLine()) != null) {
        sb.append(line + "\n");
    }
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        is.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
return sb.toString();

}

Then:

String jsonReply;
if(conn.getResponseCode()==201 || conn.getResponseCode()==200)
    {
        success = true;
        InputStream response = conn.getInputStream();
        jsonReply = convertStreamToString(response);

        // Do JSON handling here....
    }

Nope, BeautifulSoup, by itself, does not support XPath expressions.

An alternative library, lxml, does support XPath 1.0. It has a BeautifulSoup compatible mode where it'll try and parse broken HTML the way Soup does. However, the default lxml HTML parser does just as good a job of parsing broken HTML, and I believe is faster.

Once you've parsed your document into an lxml tree, you can use the .xpath() method to search for elements.

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    from urllib.request import urlopen
from lxml import etree

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = urlopen(url)
htmlparser = etree.HTMLParser()
tree = etree.parse(response, htmlparser)
tree.xpath(xpathselector)

There is also a dedicated lxml.html() module with additional functionality.

Note that in the above example I passed the response object directly to lxml, as having the parser read directly from the stream is more efficient than reading the response into a large string first. To do the same with the requests library, you want to set stream=True and pass in the response.raw object after enabling transparent transport decompression:

import lxml.html
import requests

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = requests.get(url, stream=True)
response.raw.decode_content = True
tree = lxml.html.parse(response.raw)

Of possible interest to you is the CSS Selector support; the CSSSelector class translates CSS statements into XPath expressions, making your search for td.empformbody that much easier:

from lxml.cssselect import CSSSelector

td_empformbody = CSSSelector('td.empformbody')
for elem in td_empformbody(tree):
    # Do something with these table cells.

Coming full circle: BeautifulSoup itself does have very complete CSS selector support:

for cell in soup.select('table#foobar td.empformbody'):
    # Do something with these table cells.

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

for me i solved it like the following In Visual Studio 2015 : From View menu click Other Windows then click Package Manager Console then run the following commands :

PM> enable-migrations

Migrations have already been enabled in project 'mvcproject'. To overwrite the existing migrations configuration, use the -Force parameter.

PM> enable-migrations -Force

Checking if the context targets an existing database... Code First Migrations enabled for project mvcproject.

then add the migration name under the migration folder it will add the class you need in Solution Explorer by run the following command

PM>Add-migration AddColumnUser

Finally update the database

PM> update-database 

    <?php
    // Turn off error reporting
    error_reporting(0);

    // Report runtime errors
    error_reporting(E_ERROR | E_WARNING | E_PARSE);

    // Report all errors
    error_reporting(E_ALL);

    // Same as error_reporting(E_ALL);
    ini_set("error_reporting", E_ALL);

    // Report all errors except E_NOTICE
    error_reporting(E_ALL & ~E_NOTICE);
    ?>

While your site is live, the php.ini file should have display_errors disabled for security reasons. However, for the development environment, display_errors can be enabled for troubleshooting.

There is not a really pythonic way of repeating something. However, it is a better way:

map(lambda index:do_something(), xrange(10))

If you need to pass the index then:

map(lambda index:do_something(index), xrange(10))

Consider that it returns the results as a collection. So, if you need to collect the results it can help.

I use eUML2 plugin from Soyatec, under Eclipse and it works fine for the generation of UML giving the source code. This tool is useful up to Eclipse 4.4.x

For Java Developers who use SpringBoot, ÜBER/FAT JAR is normally the final result of the package phase of maven (or build task if you use gradle).

Inside the Fat JAR one can find a META-INF directory inside which the MANIFEST.MF file lives with all the info regarding the Main class. More importantly, at the same level of META-INF directory you find the BOOT-INF directory inside which the directory lib lives and contains all the .jar files that are the dependencies of your application.

To use "include" to include CSS, you have to tell PHP you're using CSS code. Add this to your header of your CSS file and make it main.php (or styles.css, or whatever):

header("Content-type: text/css; charset: UTF-8");

This might help with some user's connections, but it theoretically (read: I haven't tested it) adds processor overhead to your server and according to Steve Souder, because your computer can download multiple files at once, using include could be slower. If you have your CSS split into a dozen files, maybe it would be faster?

Vue2: if you only want to detect change on input blur (e.g. after press enter or click somewhere else) do (more info here)

<input @change="foo" v-model... >

If you wanna detect single character changes (during user typing) use

<input @keydown="foo" v-model... >

You can also use @keyup and @input events. If you wanna to pass additional parameters use in template e.g. @keyDown="foo($event, param1, param2)". Comparision below (editable version here)

Dim is short for Dimension and is used in VBA and VB6 to declare local variables.

Set on the other hand, has nothing to do with variable declarations. The Set keyword is used to assign an object variable to a new object.

Hope that clarifies the difference for you.

5. Common pitfalls when using arrays.

5.1 Pitfall: Trusting type-unsafe linking.

OK, you’ve been told, or have found out yourself, that globals (namespace scope variables that can be accessed outside the translation unit) are Evil™. But did you know how truly Evil™ they are? Consider the program below, consisting of two files [main.cpp] and [numbers.cpp]:

// [main.cpp]
#include <iostream>

extern int* numbers;

int main()
{
    using namespace std;
    for( int i = 0;  i < 42;  ++i )
    {
        cout << (i > 0? ", " : "") << numbers[i];
    }
    cout << endl;
}

// [numbers.cpp]
int numbers[42] = {1, 2, 3, 4, 5, 6, 7, 8, 9};

In Windows 7 this compiles and links fine with both MinGW g++ 4.4.1 and Visual C++ 10.0.

Since the types don't match, the program crashes when you run it.

In-the-formal explanation: the program has Undefined Behavior (UB), and instead of crashing it can therefore just hang, or perhaps do nothing, or it can send threating e-mails to the presidents of the USA, Russia, India, China and Switzerland, and make Nasal Daemons fly out of your nose.

In-practice explanation: in main.cpp the array is treated as a pointer, placed at the same address as the array. For 32-bit executable this means that the first int value in the array, is treated as a pointer. I.e., in main.cpp the numbers variable contains, or appears to contain, (int*)1. This causes the program to access memory down at very bottom of the address space, which is conventionally reserved and trap-causing. Result: you get a crash.

The compilers are fully within their rights to not diagnose this error, because C++11 §3.5/10 says, about the requirement of compatible types for the declarations,

[N3290 §3.5/10]
A violation of this rule on type identity does not require a diagnostic.

The same paragraph details the variation that is allowed:

… declarations for an array object can specify array types that differ by the presence or absence of a major array bound (8.3.4).

This allowed variation does not include declaring a name as an array in one translation unit, and as a pointer in another translation unit.

5.2 Pitfall: Doing premature optimization (memset & friends).

Not written yet

5.3 Pitfall: Using the C idiom to get number of elements.

With deep C experience it’s natural to write …

#define N_ITEMS( array )   (sizeof( array )/sizeof( array[0] ))

Since an array decays to pointer to first element where needed, the expression sizeof(a)/sizeof(a[0]) can also be written as sizeof(a)/sizeof(*a). It means the same, and no matter how it’s written it is the C idiom for finding the number elements of array.

Main pitfall: the C idiom is not typesafe. For example, the code …

#include <stdio.h>

#define N_ITEMS( array ) (sizeof( array )/sizeof( *array ))

void display( int const a[7] )
{
    int const   n = N_ITEMS( a );          // Oops.
    printf( "%d elements.\n", n );
}

int main()
{
    int const   moohaha[]   = {1, 2, 3, 4, 5, 6, 7};

    printf( "%d elements, calling display...\n", N_ITEMS( moohaha ) );
    display( moohaha );
}

passes a pointer to N_ITEMS, and therefore most likely produces a wrong result. Compiled as a 32-bit executable in Windows 7 it produces …

7 elements, calling display...
1 elements.

1. The compiler rewrites int const a[7] to just int const a[].
2. The compiler rewrites int const a[] to int const* a.
3. N_ITEMS is therefore invoked with a pointer.
4. For a 32-bit executable sizeof(array) (size of a pointer) is then 4.
5. sizeof(*array) is equivalent to sizeof(int), which for a 32-bit executable is also 4.

In order to detect this error at run time you can do …

#include <assert.h>
#include <typeinfo>

#define N_ITEMS( array )       (                               \
    assert((                                                    \
        "N_ITEMS requires an actual array as argument",        \
        typeid( array ) != typeid( &*array )                    \
        )),                                                     \
    sizeof( array )/sizeof( *array )                            \
    )

7 elements, calling display...
Assertion failed: ( "N_ITEMS requires an actual array as argument", typeid( a ) != typeid( &*a ) ), file runtime_detect ion.cpp, line 16

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

The runtime error detection is better than no detection, but it wastes a little processor time, and perhaps much more programmer time. Better with detection at compile time! And if you're happy to not support arrays of local types with C++98, then you can do that:

#include <stddef.h>

typedef ptrdiff_t   Size;

template< class Type, Size n >
Size n_items( Type (&)[n] ) { return n; }

#define N_ITEMS( array )       n_items( array )

Compiling this definition substituted into the first complete program, with g++, I got …

M:\count> g++ compile_time_detection.cpp
compile_time_detection.cpp: In function 'void display(const int*)':
compile_time_detection.cpp:14: error: no matching function for call to 'n_items(const int*&)'

M:\count> _

How it works: the array is passed by reference to n_items, and so it does not decay to pointer to first element, and the function can just return the number of elements specified by the type.

With C++11 you can use this also for arrays of local type, and it's the type safe C++ idiom for finding the number of elements of an array.

5.4 C++11 & C++14 pitfall: Using a constexpr array size function.

With C++11 and later it's natural, but as you'll see dangerous!, to replace the C++03 function

typedef ptrdiff_t   Size;

template< class Type, Size n >
Size n_items( Type (&)[n] ) { return n; }

with

using Size = ptrdiff_t;

template< class Type, Size n >
constexpr auto n_items( Type (&)[n] ) -> Size { return n; }

where the significant change is the use of constexpr, which allows this function to produce a compile time constant.

For example, in contrast to the C++03 function, such a compile time constant can be used to declare an array of the same size as another:

// Example 1
void foo()
{
    int const x[] = {3, 1, 4, 1, 5, 9, 2, 6, 5, 4};
    constexpr Size n = n_items( x );
    int y[n] = {};
    // Using y here.
}

But consider this code using the constexpr version:

// Example 2
template< class Collection >
void foo( Collection const& c )
{
    constexpr int n = n_items( c );     // Not in C++14!
    // Use c here
}

auto main() -> int
{
    int x[42];
    foo( x );
}

The pitfall: as of July 2015 the above compiles with MinGW-64 5.1.0 with -pedantic-errors, and, testing with the online compilers at gcc.godbolt.org/, also with clang 3.0 and clang 3.2, but not with clang 3.3, 3.4.1, 3.5.0, 3.5.1, 3.6 (rc1) or 3.7 (experimental). And important for the Windows platform, it does not compile with Visual C++ 2015. The reason is a C++11/C++14 statement about use of references in constexpr expressions:

A conditional-expression e is a core constant expression unless the evaluation of e, following the rules of the abstract machine (1.9), would evaluate one of the following expressions:
        ?

• an id-expression that refers to a variable or data member of reference type unless the reference has a preceding initialization and either
  • it is initialized with a constant expression or
  • it is a non-static data member of an object whose lifetime began within the evaluation of e;

One can always write the more verbose

// Example 3  --  limited

using Size = ptrdiff_t;

template< class Collection >
void foo( Collection const& c )
{
    constexpr Size n = std::extent< decltype( c ) >::value;
    // Use c here
}

… but this fails when Collection is not a raw array.

To deal with collections that can be non-arrays one needs the overloadability of an n_items function, but also, for compile time use one needs a compile time representation of the array size. And the classic C++03 solution, which works fine also in C++11 and C++14, is to let the function report its result not as a value but via its function result type. For example like this:

// Example 4 - OK (not ideal, but portable and safe)

#include <array>
#include <stddef.h>

using Size = ptrdiff_t;

template< Size n >
struct Size_carrier
{
    char sizer[n];
};

template< class Type, Size n >
auto static_n_items( Type (&)[n] )
    -> Size_carrier<n>;
// No implementation, is used only at compile time.

template< class Type, size_t n >        // size_t for g++
auto static_n_items( std::array<Type, n> const& )
    -> Size_carrier<n>;
// No implementation, is used only at compile time.

#define STATIC_N_ITEMS( c ) \
    static_cast<Size>( sizeof( static_n_items( c ).sizer ) )

template< class Collection >
void foo( Collection const& c )
{
    constexpr Size n = STATIC_N_ITEMS( c );
    // Use c here
    (void) c;
}

auto main() -> int
{
    int x[42];
    std::array<int, 43> y;
    foo( x );
    foo( y );
}

About the choice of return type for static_n_items: this code doesn't use std::integral_constant because with std::integral_constant the result is represented directly as a constexpr value, reintroducing the original problem. Instead of a Size_carrier class one can let the function directly return a reference to an array. However, not everybody is familiar with that syntax.

About the naming: part of this solution to the constexpr-invalid-due-to-reference problem is to make the choice of compile time constant explicit.

Hopefully the oops-there-was-a-reference-involved-in-your-constexpr issue will be fixed with C++17, but until then a macro like the STATIC_N_ITEMS above yields portability, e.g. to the clang and Visual C++ compilers, retaining type safety.

Related: macros do not respect scopes, so to avoid name collisions it can be a good idea to use a name prefix, e.g. MYLIB_STATIC_N_ITEMS.

Pull with rebase

A regular pull is fetch + merge, but what you want is fetch + rebase. This is an option with the pull command:

git pull --rebase

Here is another way to do this - using the API function WideCharToMultiByte:

A good reason is for security - this can prevent CSRF attacks because this header cannot be added to the AJAX request cross domain without the consent of the server via CORS.

Only the following headers are allowed cross domain:

• Accept
• Accept-Language
• Content-Language
• Last-Event-ID
• Content-Type

any others cause a "pre-flight" request to be issued in CORS supported browsers.

Without CORS it is not possible to add X-Requested-With to a cross domain XHR request.

If the server is checking that this header is present, it knows that the request didn't initiate from an attacker's domain attempting to make a request on behalf of the user with JavaScript. This also checks that the request wasn't POSTed from a regular HTML form, of which it is harder to verify it is not cross domain without the use of tokens. (However, checking the Origin header could be an option in supported browsers, although you will leave old browsers vulnerable.)

New Flash bypass discovered

You may wish to combine this with a token, because Flash running on Safari on OSX can set this header if there's a redirect step. It appears it also worked on Chrome, but is now remediated. More details here including different versions affected.

OWASP Recommend combining this with an Origin and Referer check:

This defense technique is specifically discussed in section 4.3 of Robust Defenses for Cross-Site Request Forgery. However, bypasses of this defense using Flash were documented as early as 2008 and again as recently as 2015 by Mathias Karlsson to exploit a CSRF flaw in Vimeo. But, we believe that the Flash attack can't spoof the Origin or Referer headers so by checking both of them we believe this combination of checks should prevent Flash bypass CSRF attacks. (NOTE: If anyone can confirm or refute this belief, please let us know so we can update this article)

However, for the reasons already discussed checking Origin can be tricky.

Update

Written a more in depth blog post on CORS, CSRF and X-Requested-With here.

This solved it for me: I supplied a third argument being an object.

in app.js (working with laravel and webpack):

Vue.component('news-item', require('./components/NewsItem.vue'), {
    name: 'news-item'
});

keytool -import -v -alias cacerts -keystore cacerts.jks -storepass changeit -file C:\cacerts.cer

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

This is easier than trapping the exception:

import os
if not os.path.exists(...):
    os.makedirs(...)

Disclaimer This approach requires two system calls which is more susceptible to race conditions under certain environments/conditions. If you're writing something more sophisticated than a simple throwaway script running in a controlled environment, you're better off going with the accepted answer that requires only one system call.

UPDATE 2012-07-27

I'm tempted to delete this answer, but I think there's value in the comment thread below. As such, I'm converting it to a wiki.

SLaks has the right answer... but let me be a bit more specific for people, like me, who are annoyed by this and can't find it right away :

Project -> Properties -> Application -> Target Framework -> select ".Net Framework 4"

the project will then save and reload.

When adding new models to the django api application and running the python manage.py makemigrations the tool did not detect any new models.

The strange thing was that the old models did got picked by makemigrations, but this was because they were referenced in the urlpatterns chain and the tool somehow detected them. So keep an eye on that behavior.

The problem was because the directory structure corresponding to the models package had subpackages and all the __init__.py files were empty. They must explicitly import all the required classes in each subfolder and in the models __init__.py for Django to pick them up with the makemigrations tool.

models
  +-- __init__.py          <--- empty
  +-- patient
  ¦   +-- __init__.py      <--- empty
  ¦   +-- breed.py
  ¦   +-- ...
  +-- timeline
  ¦   +-- __init__.py      <-- empty
  ¦   +-- event.py
  ¦   +-- ...

This should fulfill your requirements.

This is a comment on WebWanderer's solution regarding checking for NaN (I don't have enough rep yet to leave a formal comment). The solution reads as

if(!parseInt(variable) && variable != 0 && typeof variable === "number")

but this will fail for rational numbers which would round to 0, such as variable = 0.1. A better test would be:

if(isNaN(variable) && typeof variable === "number")

Very late but let me share what I did when I had the same issue.

Map<String, List<String>> map1 = new HashMap<>();
map1.put("India", Arrays.asList("Virat", "Mahi", "Rohit"));
map1.put("NZ", Arrays.asList("P1","P2","P3"));

Map<String, List<String>> map2 = new HashMap<>();
map2.put("India", Arrays.asList("Virat", "Mahi", "Rohit"));
map2.put("NZ", Arrays.asList("P1","P2","P4"));

Map<String, List<String>> collect4 = Stream.of(map1, map2)
                .flatMap(map -> map.entrySet().stream())
                .collect(
                        Collectors.toMap(
                                Map.Entry::getKey,
                                Map.Entry::getValue,
                                (strings, strings2) -> {
                                    List<String> newList = new ArrayList<>();
                                    newList.addAll(strings);
                                    newList.addAll(strings2);
                                    return newList;
                                }
                        )
                );
collect4.forEach((s, strings) -> System.out.println(s+"->"+strings));

It gives the following output

NZ->[P1, P2, P3, P1, P2, P4]
India->[Virat, Mahi, Rohit, Virat, Mahi, Rohit]

This is because applicationContect.xml or any_filename.XML is not placed under proper path.

Trouble shooting Steps

1: Add the XML file under the resource folder.

2: If you don't have a resource folder. Create one by navigating new by Right click on the project new > Source Folder, name it as resource and place your XML file under it.

There is no built-in way (yet) of reversing arbitrary colormaps, but one simple solution is to actually not modify the colorbar but to create an inverting Normalize object:

from matplotlib.colors import Normalize

class InvertedNormalize(Normalize):
    def __call__(self, *args, **kwargs):
        return 1 - super(InvertedNormalize, self).__call__(*args, **kwargs)

You can then use this with plot_surface and other Matplotlib plotting functions by doing e.g.

inverted_norm = InvertedNormalize(vmin=10, vmax=100)
ax.plot_surface(..., cmap=<your colormap>, norm=inverted_norm)

This will work with any Matplotlib colormap.

Layers are logical separation of related-functionality[code] within an application, Communication between layers is explicit and loosely coupled. [Presentation logic,Application logic,Data Access logic]

Tiers are Physical separation of layers [which get hosted on Individual servers] in an individual computer(process).

As shown in diagram:

1-Tier & 3-Layers « App Logic  with out DB access store data in a files.
2-Tier & 3-Layers « App Logic & DataStorage-box.
2-Tier & 2-Layers « Browser View[php] & DataStorage[procedures]
2-Tier & 1-Layers « Browser View[php] & DataStorage, query sending is common.
3-Tier & n-Layer  « Browser View[php], App Logic[jsp], DataStorage

n-Tier advantages:
Better Security
Scalability : As your organisation grows You can scale up your DB-Tier with DB-Clustering with out touching other tiers.
Maintainability : Web designer can change the View-code, with out touching the other layers on the other tiers.
Easily Upgrade or Enhance [Ex: You can add Additional Application Code, Upgrade Storage Area, or even add Multiple presentation Layers for Separate devises like mobile, tablet, pc]

Here is a more complete version of focusing on the next element. It follows the spec guidelines and sorts the list of elements correctly by using tabindex. Also a reverse variable is defined if you want to get the previous element.

function focusNextElement( reverse, activeElem ) {
  /*check if an element is defined or use activeElement*/
  activeElem = activeElem instanceof HTMLElement ? activeElem : document.activeElement;

  let queryString = [
      'a:not([disabled]):not([tabindex="-1"])',
      'button:not([disabled]):not([tabindex="-1"])',
      'input:not([disabled]):not([tabindex="-1"])',
      'select:not([disabled]):not([tabindex="-1"])',
      '[tabindex]:not([disabled]):not([tabindex="-1"])'
      /* add custom queries here */
    ].join(','),
    queryResult = Array.prototype.filter.call(document.querySelectorAll(queryString), elem => {
      /*check for visibility while always include the current activeElement*/
      return elem.offsetWidth > 0 || elem.offsetHeight > 0 || elem === activeElem;
    }),
    indexedList = queryResult.slice().filter(elem => {
      /* filter out all indexes not greater than 0 */
      return elem.tabIndex == 0 || elem.tabIndex == -1 ? false : true;
    }).sort((a, b) => {
      /* sort the array by index from smallest to largest */
      return a.tabIndex != 0 && b.tabIndex != 0 
        ? (a.tabIndex < b.tabIndex ? -1 : b.tabIndex < a.tabIndex ? 1 : 0) 
        : a.tabIndex != 0 ? -1 : b.tabIndex != 0 ? 1 : 0;
    }),
    focusable = [].concat(indexedList, queryResult.filter(elem => {
      /* filter out all indexes above 0 */
      return elem.tabIndex == 0 || elem.tabIndex == -1 ? true : false;
    }));

  /* if reverse is true return the previous focusable element
     if reverse is false return the next focusable element */
  return reverse ? (focusable[focusable.indexOf(activeElem) - 1] || focusable[focusable.length - 1]) 
    : (focusable[focusable.indexOf(activeElem) + 1] || focusable[0]);
}

I have the following in my ~/.bash_profile:

if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

If I had .bashrc instead of ~/.bashrc, I'd be seeing the same symptom you're seeing.

I recently had a similar experience (sql server 2012). I did not have the luxury of controlling the input, I just had a requirement to report on it. Luckily the dates were entered with leading 3 character alpha month abbreviations, so this made it simple & quick:

TRY_CONVERT(DATETIME,REPLACE(obs.DateValueText,SUBSTRING(obs.DateValueText,1,3),CHARINDEX(SUBSTRING(obs.DateValueText,1,3),'...JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC')/4)) 

It worked for 12 hour:
Feb-14-2015 5:00:00 PM 2015-02-14 17:00:00.000
and 24 hour times:
Sep-27-2013 22:45 2013-09-27 22:45:00.000

(thanks ryanyuyu)

for date-time comparison, you can use valueOf function of the moment which provides milliseconds of the date-time, which is best for comparison:

let date1 = moment('01-02-2020','DD-MM-YYYY').valueOf()_x000D_
let date2 = moment('11-11-2012','DD-MM-YYYY').valueOf()_x000D_
_x000D_
//     alert((date1 > date2 ? 'date1' : 'date2') + " is greater..."  )_x000D_
_x000D_
if (date1 > date2) {_x000D_
   alert("date1 is greater..." )_x000D_
} else {_x000D_
   alert("date2 is greater..." )_x000D_
}

Mad a similar error, easy to fix:

    TypeError Traceback (most recent call last) <ipython-input-2-1eb12bfdc7db> in <module>
  3 mylist = [10,20,30] ----> 4 arr = np.array[(10,20,30)] 5 d = {'a':10, 'b':20, 'c':30} TypeError: 'builtin_function_or_method' object is not subscriptable

but I should have written it as:

arr = np.array([10,20,30])

Very fixable, rookie/dumb mistake.

<MyComponent /> compiles to React.createElement(MyComponent, {}), which expects a string (HTML tag) or a function (ReactClass) as first parameter.

You could just store your component class in a variable with a name that starts with an uppercase letter. See HTML tags vs React Components.

var MyComponent = Components[type + "Component"];
return <MyComponent />;

compiles to

var MyComponent = Components[type + "Component"];
return React.createElement(MyComponent, {});

If the server doesn't have enough memory also will cause this problem. This is my personal experience with Godaddy VPS.

If you use function components and don't want to use a forwardRef to measure your component's absolute layout, you can get a reference to it from the LayoutChangeEvent in the onLayout callback.

This way, you can get the absolute position of the element:

<MyFunctionComp
  onLayout={(event) => {
    event.target.measure(
      (x, y, width, height, pageX, pageX) => {
        doSomethingWithAbsolutePosition({
          x: x + pageX, 
          y: y + pageY,
        });
      },
    );
  }}
/>

Short Answer

super(DerivedClass, self).__init__()

Long Answer

What does super() do?

It takes specified class name, finds its base classes (Python allows multiple inheritance) and looks for the method (__init__ in this case) in each of them from left to right. As soon as it finds method available, it will call it and end the search.

How do I call init of all base classes?

Above works if you have only one base class. But Python does allow multiple inheritance and you might want to make sure all base classes are initialized properly. To do that, you should have each base class call init:

class Base1:
  def __init__():
    super(Base1, self).__init__()

class Base2:
  def __init__():
    super(Base2, self).__init__()

class Derived(Base1, Base2):
  def __init__():
    super(Derived, self).__init__()

What if I forget to call init for super?

The constructor (__new__) gets invoked in a chain (like in C++ and Java). Once the instance is created, only that instance's initialiser (__init__) is called, without any implicit chain to its superclass.

Alternatively you can use the views current layout parameters and modify them:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) viewToLayout.getLayoutParams();
params.addRule(RelativeLayout.BELOW, R.id.below_id);

These look the same as their real counterparts in Safari, Chrome, and Firefox. They degrade gracefully and look OK in Opera and IE9, too.

It's been quite some time but it's a core part of the stdlib and has dozens of potential methods so I think it's useful to have some benchmarks for the different suggestions and include the numpy method which can be by far the fastest.

import random
from timeit import timeit
import numpy as np

l = [random.random() for i in range(10**4)]
l[10**4 - 100] = 5

# method 1
def fun1(l:list, x:int, e = -1) -> int:
    return [[i for i,elem in enumerate(l) if elem == x] or [e]][0]

# method 2
def fun2(l:list, x:int, e = -1) -> int:
    for i,elem in enumerate(l):
        if elem == x:
            return i
    else:
        return e

# method 3
def fun3(l:list, x:int, e = -1) -> int:
    try:
        idx = l.index(x)
    except ValueError:
        idx = e
    return idx

# method 4
def fun4(l:list, x:int, e = -1) -> int:
    return l.index(x) if x in l else e

l2 = np.array(l)
# method 5
def fun5(l:list or np.ndarray, x:int, e = -1) -> int:
    res = np.where(np.equal(l, x))
    if res[0].any():
        return res[0][0]
    else:        
        return e


if __name__ == "__main__":
    print("Method 1:")
    print(timeit(stmt = "fun1(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 2:")
    print(timeit(stmt = "fun2(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 3:")
    print(timeit(stmt = "fun3(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 4:")
    print(timeit(stmt = "fun4(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 5, numpy given list:")
    print(timeit(stmt = "fun5(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 6, numpy given np.ndarray:")
    print(timeit(stmt = "fun5(l2, 5)", number = 1000, globals = globals()))
    print("")

When run as main, this results in the following printout on my machine indicating time in seconds to complete 1000 trials of each function:

Method 1: 0.7502102799990098

Method 2: 0.7291318440002215

Method 3: 0.24142152300009911

Method 4: 0.5253471979995084

Method 5, numpy given list: 0.5045417560013448

Method 6, numpy given np.ndarray: 0.011147511999297421

Of course the question asks specifically about lists so the best solution is to use the try-except method, however the speed improvements (at least 20x here compared to try-except) offered by using the numpy data structures and operators instead of python data structures is significant and if building something on many arrays of data that is performance critical then the author should try to use numpy throughout to take advantage of the superfast C bindings. (CPython interpreter, other interpreter performances may vary)

Btw, the reason Method 5 is much slower than Method 6 is because numpy first has to convert the given list to it's own numpy array, so giving it a list doesn't break it it just doesn't fully utilise the speed possible.

DISCLAIMER: The below solution does not preserve trailing tabs.

If you know the exact number of lines in the text file, try the following method:

@ECHO OFF
SET origfile=original file
SET tempfile=temporary file
SET insertbefore=4
SET totallines=200
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /P L=
  IF %%i==%insertbefore% ECHO(
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%
COPY /Y %tempfile% %origfile% >NUL
DEL %tempfile%

The loop reads lines from the original file one by one and outputs them. The output is redirected to a temporary file. When a certain line is reached, an empty line is output before it.

After finishing, the original file is deleted and the temporary one gets assigned the original name.

UPDATE

If the number of lines is unknown beforehand, you can use the following method to obtain it:

FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C

(This line simply replaces the SET totallines=200 line in the above script.)

The method has one tiny flaw: if the file ends with an empty line, the result will be the actual number of lines minus one. If you need a workaround (or just want to play safe), you can use the method described in this answer.

You can use the method Substring method that takes a single parameter, which is the index to start from.

In my code below i deal with the case were the length is less than your desired start index and when the length is zero.

string s = "hello world!";
s = s.Substring(Math.Max(0, Math.Min(10, s.Length - 1)));

Key differences:

C++ is a general-purpose programming language, but is developed from the originally C programming language. It was developed by Bjarne Stroustrup at Bell Labs starting in 1979. C++ was originally named C with Classes. It was renamed C++ in 1983.

Visual C++, on the other hand, is not a programming language at all. It is in fact a development environment. It is an “integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages.” Microsoft Visual C++, also known as MSVC or VC++, is sold as part of the Microsoft Visual Studio app.

Implementation in Java : Using codaddict's algorithm:

import java.util.Hashtable;
public class Range {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    Hashtable mapping = new Hashtable();
    int a[]= {80,79,82,81,84,83,85};
    int k = 160;

    for (int i=0; i < a.length; i++){
        mapping.put(a[i], i);
    }

    for (int i=0; i < a.length; i++){
        if (mapping.containsKey(k - a[i]) && (Integer)mapping.get(k-a[i]) != i){
            System.out.println(k-a[i]+", "+ a[i]);
        }
    }      

}

}

Output:

81, 79
79, 81

If you want duplicate pairs (eg: 80,80) also then just remove && (Integer)mapping.get(k-a[i]) != i from the if condition and you are good to go.

Or you can use an alternative:

https://github.com/kint-php/kint

It works with zero set up and has much more features than Xdebug's var_dump anyway. To bypass the nested limit on the fly with Kint, just use

 +d( $variable ); // append `+` to the dump call

Reason of comments:

1. Comment out elements temporarily rather than removing them, especially if they've been left unfinished.
2. Write notes or reminders to yourself inside your actual HTML documents.
3. Create notes for other scripting languages like JavaScript which requires them

HTML Comments

<!-- Everything is invisible  -->

Gosha Arinich is right, you should return your <li> element. But, nevertheless, you should get nasty red warning in the browser console in this case

Each child in an array or iterator should have a unique "key" prop.

so, you need to add "key" to your list:

this.state.data.map(function(item, i){
  console.log('test');
  return <li key={i}>Test</li>
})

or drop the console.log() and do a beautiful oneliner, using es6 arrow functions:

this.state.data.map((item,i) => <li key={i}>Test</li>)

IMPORTANT UPDATE:

The answer above is solving the current problem, but as Sergey mentioned in the comments: using the key depending on the map index is BAD if you want to do some filtering and sorting. In that case use the item.id if id already there, or just generate unique ids for it.

I had the exact same problem, this - "meta http-equiv="X-UA-Compatible" content="IE=7">" works great in IE8 and IE9, but not in IE10. There is a bug in the server browser definition files that shipped with .NET 2.0 and .NET 4, namely that they contain definitions for a certain range of browser versions. But the versions for some browsers (like IE 10) aren't within those ranges any more. Therefore, ASP.NET sees them as unknown browsers and defaults to a down-level definition, which has certain inconveniences, like that it does not support features like JavaScript.

My thanks to Scott Hanselman for this fix.

Here is the link -

This MS KP fix just adds missing files to the asp.net on your server. I installed it and rebooted my server and it now works perfectly. I would have thought that MS would have given this fix a wider distribution.

I prefer to use

<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>

that works well

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

JUnit 4.7 added this feature it seems using TestName-Rule. Looks like this will get you the method name:

import org.junit.Rule;

public class NameRuleTest {
    @Rule public TestName name = new TestName();

    @Test public void testA() {
        assertEquals("testA", name.getMethodName());
    }

    @Test public void testB() {
        assertEquals("testB", name.getMethodName());
    }
}

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

We can use Xcode Formatter which uses uncrustify to easily format your source code as your team exactly wants to be!.

Installation The recommended way is to clone GitHub project or download it from https://github.com/octo-online/Xcode-formatter and add the CodeFormatter directory in your Xcode project to get : Xcode shortcut-based code formatting: a shortcut to format modified sources in the current workspace automatic code formatting: add a build phase to your project to format current sources when application builds all sources formatting: format all your code with one command line your formatting rules shared by project: edit and use a same configuration file with your project dev team 1) How to setup the code formatter for your project Install uncrustify The simplest way is to use brew: $ brew install uncrustify

To install brew: $ ruby –e “$(curl –fsSkl raw.github.com/mxcl/homebrew/go)”

Check that uncrustify is located in /usr/local/bin $ which uncrustify

If your uncrustify version is lower than 0.60, you might have to install it manually since modern Objective-C syntax has been added recently. Add CodeFormatter directory beside your .xcodeproj file

Check that your Xcode application is named "Xcode" (default name) You can see this name in the Applications/ directory (or your custom Xcode installation directory). Be carefull if you have multiple instances of Xcode on your mac: ensure that project's one is actually named "Xcode"! (Why this ? This name is used to find currently opened Xcode files. See CodeFormatter/Uncrustify_opened_Xcode_sources.workflow appleScript). Install the automator service Uncrustify_opened_Xcode_sources.workflow Copy this file to your ~/Library/Services/ folder (create this folder if needed).Be careful : by double-clicking the .workflow file, you will install it but the file will be removed! Be sure to leave a copy of it for other users.

How to format opened files when building the project Add a build phase "run script" containing the following line:

sh CodeFormatter/scripts/formatOpendSources.sh

How to format files in command line

To format currently opened files, use formatOpenedSources.sh:

$sh CodeFormatter/scripts/formatOpendSources.sh

To format all files, use formatAllSources.sh:

$sh CodeFormatter/scripts/formatAllSources.sh PATH

PATH must be replaced by your sources path.

E:g; if project name is TestApp then the command will be

$sh CodeFormatter/scripts/formatAllSources.sh TestApp

it will look for all files in the project and will format all the files as configured in uncrustify_objective_c.cfg file.

How to change formatter’s rules

Turns out I don't have enough reputation to put this as a comment, which would be a more appropriate place for this:

Re. AllBlackt's answer, if you prefer Ansible's multiline format you need to adjust the quoting for state (I spent a few minutes working this out, so hopefully this speeds someone else up),

- stat:
    path: "/etc/nologin"
  register: p

- name: create fake 'nologin' shell
  file:
    path: "/etc/nologin"
    owner: root
    group: sys
    mode: 0555
    state: '{{ "file" if  p.stat.exists else "touch" }}'

To only modify the title's font (and not the font of the axis) I used this:

import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})

The fontdict accepts all kwargs from matplotlib.text.Text.

Others have answered your earlier question. For this:

As an addendum, is there any way to extract directly with the header names rather than with column numbers?

I haven't tried it, but you could store each header's index in a hash and then use that hash to get its index later on.

for(i=0;i<$NF;i++){
    hash[$i] = i;
}

Then later on, use it:

j = hash["header1"];
print $j;

You can also make use of until command:

until ((0)); do foo; sleep 2; done

Note that in contrast to while, until would execute the commands inside the loop as long as the test condition has an exit status which is not zero.

Using a while loop:

while read i; do foo; sleep 2; done < /dev/urandom

Using a for loop:

for ((;;)); do foo; sleep 2; done

Another way using until:

until [ ]; do foo; sleep 2; done

Important Note

I had to COPY and untar java package in my docker image. When I compared the docker image size created using ADD it was 180MB bigger than the one created using COPY, tar -xzf *.tar.gz and rm *.tar.gz

This means that although ADD removes the tar file, it is still kept somewhere. And its making the image bigger!!

I have had the same problem and came acrosse this site.

the solution to just set another "filename" in the

... for output as ... command was very simple and useful.

in addition (beyond the Application.GetSaveAsFilename() Dialog)

it is very simple to set a** new filename** just using

the replace command, so you may change the filename/extension

eg. (as from the first post)

sFileName = "C:\filelocation"
iFileNum = FreeFile

Open sFileName For Input As iFileNum
content = (...edit the content) 

Close iFileNum

now just set:

newFilename = replace(sFilename, ".txt", ".csv") to change the extension

or

newFilename = replace(sFilename, ".", "_edit.") for a differrent filename

and then just as before

iFileNum = FreeFile
Open newFileName For Output As iFileNum

Print #iFileNum, content
Close iFileNum 

I surfed over an hour to find out how to rename a txt-file,

with many different solutions, but it could be sooo easy :)

I found xunit-viewer, which has deprecated junit-viewer mentioned by @daniel-kristof-kiss.

It is very simple, automatically recursively collects all relevant files in ANT Junit XML format and creates a single html-file with filtering and other sweet features.

I use it to upload test results from Travis builds as Travis has no other support for collecting standard formatted test results output.

This kind of functionality is built in.

When using a decimal you can use a format string "C" or "c".

decimal dec = 123.00M;
string uk = dec.ToString("C", new CultureInfo("en-GB")); // uk holds "£123.00"
string us = dec.ToString("C", new CultureInfo("en-US")); // us holds "$123.00"

Well, what do you try to do? If you want to use division, use "/" not "\". If it is something else, explain it in a bit more detail, please.

@IBAction func btn_LogIn(sender: AnyObject) {

    let postString = "email: [email protected] & password: testtest"
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request){data, response, error in
        guard error == nil && data != nil else{
            print("error")
            return
        }
        if let httpStatus = response as? NSHTTPURLResponse where httpStatus.statusCode != 200{
            print("statusCode should be 200, but is \(httpStatus.statusCode)")

        }

A belated post:
Use the search regex pattern as a Record Separator (RS) in awk
This allows your regex to span \n-delimited lines (if you need it).

printf 'X \n moo X\n XX\n' | 
   awk -vRS='X[^X]*X' 'END{print (NR<2?0:NR-1)}'

Use make (chan int) instead of nil. The first value has to be the same type that your map holds.

package main

import "fmt"

func main() {

    var sessions = map[string] chan int{}
    sessions["somekey"] = make(chan int)

    fmt.Printf ("%d\n", len(sessions)) // 1

    // Remove somekey's value from sessions
    delete(sessions, "somekey")

    fmt.Printf ("%d\n", len(sessions)) // 0
}

UPDATE: Corrected my answer.

var nvc = new List<KeyValuePair<string, string>>();
nvc.Add(new KeyValuePair<string, string>("Input1", "TEST2"));
nvc.Add(new KeyValuePair<string, string>("Input2", "TEST2"));
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, url) { Content = new FormUrlEncodedContent(nvc) };
var res = await client.SendAsync(req);

Or

var dict = new Dictionary<string, string>();
dict.Add("Input1", "TEST2");
dict.Add("Input2", "TEST2");
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, url) { Content = new FormUrlEncodedContent(dict) };
var res = await client.SendAsync(req);

Rather than finding top view controller, one can use

viewController.modalPresentationStyle = UIModalPresentationStyle.currentContext

Where viewController is the controller which you want to present This is useful when there are different kinds of views in hierarchy like TabBar, NavBar, though others seems to be correct but more sort of hackish

The other presentation style can be found on apple doc

The below JavaScript code sends "text" to be spoken/converted to mp3 audio to google cloud text-to-speech API and gets mp3 audio content as response back.

    const data = {
      'input':{

      },

        },
        body:JSON.stringify(data),
        method:"POST"
     };
    fetch(url,otherparam)

MYSQL has no explode() like function built in. But you can easily add similar function to your DB and then use it from php queries. That function will look like:

CREATE FUNCTION SPLIT_STRING(str VARCHAR(255), delim VARCHAR(12), pos INT)
RETURNS VARCHAR(255)
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(str, delim, pos),
       CHAR_LENGTH(SUBSTRING_INDEX(str, delim, pos-1)) + 1),
       delim, '');

Usage:

SELECT SPLIT_STRING('apple, pear, melon', ',', 1)

The example above will return apple. I think that it will be impossible to return array in MySQL so you must specify which occurrence to return explicitly in pos. Let me know if you succeed using it.

That's the same behavior I've seen: iframe's load() will fire first on an empty iframe, then the second time when your page is loaded.

Edit: Hmm, interesting. You could increment a counter in your event handler, and a) ignore the first load event, or b) ignore any duplicate load event.

Check Is Initial View Controller in the Attributes Inspector.

Take one example - you have a table with huge data per row. That means every instance of the object is Big.

If you use B tree here then most of the time is spent scanning the pages with data - which is of no use. In databases that is the reason of using B+ Trees to avoid scanning object data.

B+ Trees separate keys from data.

But if your data size is less then you can store them with key which is what B tree does.

In addition to what @berguiga-mohamed-amine stated, I just found that a wildcard requires leaving the module argument the empty string:

compile ("com.github.jsonld-java:jsonld-java:$jsonldJavaVersion") {
    exclude group: 'org.apache.httpcomponents', module: ''
    exclude group: 'org.slf4j', module: ''
}

For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2 MIME type, only about .woff. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2, then updated .woff.)

Second, and more importantly, I was bundling bootstrap.css along with some other files as "~/bundles/css/site". Meanwhile, my font files were in "~/fonts". bootstrap.css looks for the glyphicon fonts in "../fonts", which translated to "~/bundles/fonts" -- wrong path.

In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss", and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts" for the glyphicon files, which worked. Problem solved.

Before I fixed the second problem above, none of the glyphicon font files were loading. The symptom was that all instances of glyphicon glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.

Here is my simple version. Every time you hit a key, delete all from console and draw as many '*' as the length of password string is.

int chr = 0;
string pass = "";
const int ENTER = 13;
const int BS = 8;

do
{
   chr = Console.ReadKey().KeyChar;
   Console.Clear(); //imediately clear the char you printed

   //if the char is not 'return' or 'backspace' add it to pass string
   if (chr != ENTER && chr != BS) pass += (char)chr;

   //if you hit backspace remove last char from pass string
   if (chr == BS) pass = pass.Remove(pass.Length-1, 1);

   for (int i = 0; i < pass.Length; i++)
   {
      Console.Write('*');
   }
} 
 while (chr != ENTER);

Console.Write("\n");
Console.Write(pass);

Console.Read(); //just to see the pass

df.tail(1).index 

seems the most readable

You can find more information about the date pipe here, such as formats.

If you want to use it in your component, you can simply do

pipe = new DatePipe('en-US'); // Use your own locale

Now, you can simply use its transform method, which will be

const now = Date.now();
const myFormattedDate = this.pipe.transform(now, 'short');

Interesting question, I tried doing this by just doing a fixed position row, but this way seems to be a much better one. Source at bottom.

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

HTML5 has several goals which differentiate it from HTML4.

Consistency in Handling Malformed Documents

The primary one is consistent, defined error handling. As you know, HTML purposely supports 'tag soup', or the ability to write malformed code and have it corrected into a valid document. The problem is that the rules for doing this aren't written down anywhere. When a new browser vendor wants to enter the market, they just have to test malformed documents in various browsers (especially IE) and reverse-engineer their error handling. If they don't, then many pages won't display correctly (estimates place roughly 90% of pages on the net as being at least somewhat malformed).

So, HTML5 is attempting to discover and codify this error handling, so that browser developers can all standardize and greatly reduce the time and money required to display things consistently. As well, long in the future after HTML has died as a document format, historians may still want to read our documents, and having a completely defined parsing algorithm will greatly aid this.

Better Web Application Features

The secondary goal of HTML5 is to develop the ability of the browser to be an application platform, via HTML, CSS, and Javascript. Many elements have been added directly to the language that are currently (in HTML4) Flash or JS-based hacks, such as <canvas>, <video>, and <audio>. Useful things such as Local Storage (a js-accessible browser-built-in key-value database, for storing information beyond what cookies can hold), new input types such as date for which the browser can expose easy user interface (so that we don't have to use our js-based calendar date-pickers), and browser-supported form validation will make developing web applications much simpler for the developers, and make them much faster for the users (since many things will be supported natively, rather than hacked in via javascript).

Improved Element Semantics

There are many other smaller efforts taking place in HTML5, such as better-defined semantic roles for existing elements (<strong> and <em> now actually mean something different, and even <b> and <i> have vague semantics that should work well when parsing legacy documents) and adding new elements with useful semantics - <article>, <section>, <header>, <aside>, and <nav> should replace the majority of <div>s used on a web page, making your pages a bit more semantic, but more importantly, easier to read. No more painful scanning to see just what that random </div> is closing - instead you'll have an obvious </header>, or </article>, making the structure of your document much more intuitive.

std::string replace(const std::string & in
                  , const std::string & from
                  , const std::string & to){
  if(from.size() == 0 ) return in;
  std::string out = "";
  std::string tmp = "";
  for(int i = 0, ii = -1; i < in.size(); ++i) {
    // change ii
    if     ( ii <  0 &&  from[0] == in[i] )  {
      ii  = 0;
      tmp = from[0]; 
    } else if( ii >= 0 && ii < from.size()-1 )  {
      ii ++ ;
      tmp = tmp + in[i];
      if(from[ii] == in[i]) {
      } else {
        out = out + tmp;
        tmp = "";
        ii = -1;
      }
    } else {
      out = out + in[i];
    }
    if( tmp == from ) {
      out = out + to;
      tmp = "";
      ii = -1;
    }
  }
  return out;
};

Alternative solution that won't append a spurious CR-LF:

$original_file ='C:\Users\abc\Desktop\File\abc.txt'
$text = [IO.File]::ReadAllText($original_file) -replace "`r`n", "`n"
[IO.File]::WriteAllText($original_file, $text)

Pretty late answer but none of the above helped my case and was something different

while referring the javascript file type="text/javascript" was missing in the legacy application i was working

<script  src="ab.js" ></script>

below one worked and breakpoints were hitting as expected

 <script  src="ab.js" type="text/javascript"></script>

ps axuwww | grep java | grep -v grep

The above will

• show you all processes with long lines (arg: www)
• filter (grep) only lines what contain the word java, and
• filter out the line "grep java" :)

(btw, this example is not the effective one, but simple to remember) ;)

you can pipe the above to another commands, for example:

ps axuwww | grep java | grep -v grep | sed '.....'  | while read something
do
    something_another $something
done

etc...

Check your php error log which might be a separate file from your apache error log.

Find it by going to phpinfo() and check for error_log attribute. If it is not set. Set it: https://stackoverflow.com/a/12835262/445131

Maybe your post_max_size is too small for what you're trying to post, or one of the other max memory settings is too low.

Example from current code I'm working with:

int index=-1;
for (Policy rule : rules)
{   
     index++;
     // do stuff here
}

Lets you cleanly start with an index of zero, and increment as you process.

MultipleIE , IETester there are many similar to those.

Multiple IE supports IE3 IE4.01 IE5 IE5.5 and IE6 and "is no longer maintained and there are no plans to continue maintaining it! Thanks and good luck!".

IETester seems a better choice : IE10, IE9, IE8, IE7 IE 6 and IE5.5 on Windows 8 desktop, Windows 7, Vista and XP

On a x64 system, system32 is for 64 bit and syswow64 is for 32 bit (not the other way around as stated in another answer). WOW (Windows on Windows) is the 32 bit subsystem that runs under the 64 bit subsystem).

It's a mess in naming terms, and serves only to confuse, but that's the way it is.

Again ...

syswow64 is 32 bit, NOT 64 bit.

system32 is 64 bit, NOT 32 bit.

There is a regsrv32 in each of these directories. One is 64 bit, and the other is 32 bit. It is the same deal with odbcad32 and et al. (If you want to see 32-bit ODBC drivers which won't show up with the default odbcad32 in system32 which is 64-bit.)

Every instance of View calls getViewTreeObserver(). Now when holding an instance of ViewTreeObserver, you can add an OnScrollChangedListener() to it using the method addOnScrollChangedListener().

You can see more information about this class here.

It lets you be aware of every scrolling event - but without the coordinates. You can get them by using getScrollY() or getScrollX() from within the listener though.

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        int scrollY = rootScrollView.getScrollY(); // For ScrollView
        int scrollX = rootScrollView.getScrollX(); // For HorizontalScrollView
        // DO SOMETHING WITH THE SCROLL COORDINATES
    }
});

None of the most-upvoted answers worked for me in Chrome 79. It looks like Chrome changed its behavior with respect to the Back button after version 75. See here:

https://support.google.com/chrome/thread/8721521?hl=en

However, in that Google thread, the answer provided by Azrulmukmin Azmi at the very end did work. This is his solution.

<script>
    history.pushState(null, document.title, location.href);
    history.back();
    history.forward();
    window.onpopstate = function () {
        history.go(1);
    };
</script>

The problem with Chrome is that it doesn't trigger onpopstate event unless you make browser action ( i.e. call history.back). That's why I've added those to script.

I don't entirely understand what he wrote, but apparently an additional history.back() / history.forward() is now required for blocking Back in Chrome 75+.

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

There is a very easy way to catch any kind of exception (division by zero, access violation, etc.) in Visual Studio using try -> catch (...) block. A minor project settings tweaking is enough. Just enable /EHa option in the project settings. See Project Properties -> C/C++ -> Code Generation -> Modify the Enable C++ Exceptions to "Yes With SEH Exceptions". That's it!

this is select box html

<select name="selectBox" id="selectBox">
<option value="option1">option1</option>
<option value="option2">option2</option>
<option value="option3">option3</option>
<option value="option4">option4</option>    
</select>

when you want to totally remove and add option from select box then you can use this code

$("#selectBox option[value='option1']").remove();
$("#selectBox").append('<option value="option1">Option</option>');

sometime we need to hide and show option from select box , but not remove then you can use this code

 $("#selectBox option[value='option1']").hide();
 $("#selectBox option[value='option1']").show();

sometime need to remove selected option from select box then

$('#selectBox :selected').remove();
$("#selectBox option:selected").remove();

when you need to remove all option then this code

('#selectBox').empty();

when need to first option or last then this code

$('#selectBox').find('option:first').remove();
$('#selectBox').find('option:last').remove();

I needed one line version for short array:

($array = [1, 2, 3, 4])[mt_rand(0, count($array) - 1)]

or if array is fixed:

[1, 2, 3, 4][mt_rand(0, 3]

I am researching the same thing and stumbled upon identityserver which implements OAuth and OpenID on top of ASP.NET. It integrates with ASP.NET identity and Membership Reboot with persistence support for Entity Framework.

So, to answer your question, check out their detailed document on how to setup an OAuth and OpenID server.

This may be what you want. Settings -> Appearance & Behavior -> System Settings > Project Opening > Default Directory

1. Open 'Preferences'
2. Select System Settings -> Project Opening
3. Set 'Default Directory' where you want.

It worked for me. I tried Android Studio 3.5.
