The following approach was inspired by this answer to a related (more general) question.

The approach is to read the MachineGuid value in registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography. This value is generated during OS installation.

There are few ways around the uniqueness of the Hardware-ID per machine using this approach. One method is editing the registry value, but this would cause complications on the user's machine afterwards. Another method is to clone a drive image which would copy the MachineGuid value.

However, no approach is hack-proof and this will certainly be good enough for normal users. On the plus side, this approach is quick performance-wise and simple to implement.

public string GetMachineGuid()
{
   string location = @"SOFTWARE\Microsoft\Cryptography";
   string name = "MachineGuid";

   using (RegistryKey localMachineX64View = 
       RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
   {
       using (RegistryKey rk = localMachineX64View.OpenSubKey(location))
       {
           if (rk == null)
               throw new KeyNotFoundException(
                   string.Format("Key Not Found: {0}", location));

           object machineGuid = rk.GetValue(name);
           if (machineGuid == null)
               throw new IndexOutOfRangeException(
                   string.Format("Index Not Found: {0}", name));

           return machineGuid.ToString();
       }
   }
}

You have to escape the & character. Turn your

&

into

&

and you should be good.

You can use querySelectorAll() like this:

var test = document.querySelectorAll('input[value][type="checkbox"]:not([value=""])');

This translates to:

get all inputs with the attribute "value" and has the attribute "value" that is not blank.

In this demo, it disables the checkbox with a non-blank value.

You want huge?

Here's a small table: create table foo (id int not null primary key auto_increment, crap char(2000));

insert into foo(crap) values ('');

-- each time you run the next line, the number of rows in foo doubles. insert into foo( crap ) select * from foo;

run it twenty more times, you have over a million rows to play with.

Yes, if he's looking for looks of relations to navigate, this is not the answer. But if by huge he means to test performance and his ability to optimize, this will do it. I did exactly this (and then updated with random values) to test an potential answer I had for another question. (And didn't answer it, because I couldn't come up with better performance than what that asker had.)

Had he asked for "complex", I'd have gien a differnt answer. To me,"huge" implies "lots of rows".

Because you don't need huge to play with tables and relations. Consider a table, by itself, with no nullable columns. How many different kinds of rows can there be? Only one, as all columns must have some value as none can be null.

Every nullable column multiples by two the number of different kinds of rows possible: a row where that column is null, an row where it isn't null.

Now consider the table, not in isolation. Consider a table that is a child table: for every child that has an FK to the parent, that, is a many-to-one, there can be 0, 1 or many children. So we multiply by three times the count we got in the previous step (no rows for zero, one for exactly one, two rows for many). For any grandparent to which the parent is a many, another three.

For many-to-many relations, we can have have no relation, a one-to-one, a one-to-many, many-to-one, or a many-to-many. So for each many-to-many we can reach in a graph from the table, we multiply the rows by nine -- or just like two one-to manys. If the many-to-many also has data, we multiply by the nullability number.

Tables that we can't reach in our graph -- those that we have no direct or indirect FK to, don't multiply the rows in our table.

By recursively multiplying the each table we can reach, we can come up with the number of rows needed to provide one of each "kind", and we need no more than those to test every possible relation in our schema. And we're nowhere near huge.

That is known as a textbox watermark, and it is done via JavaScript.

• http://naspinski.net/post/Text-Input-Watermarks-using-Javascript-(IE-Compatible).aspx

or if you use jQuery, a much better approach:

• http://digitalbush.com/projects/watermark-input-plugin/
• or code.google.com/p/jquery-watermark

CSS can not be used to animation, or any style modification on events.

The only way is to use a javascript function, which will return the width of a given element, then, subtract 100px to it, and set the new width size.

Assuming you are using jQuery, you could do something like that:

oldWidth = $('#yourElem').width();
$('#yourElem').width(oldWidth-100);

And with native javascript:

oldWidth = document.getElementById('yourElem').clientWidth;
document.getElementById('yourElem').style.width = oldWidth-100+'px';

We assume that you have a css style set with 100%;

Using the provided IntentInegrator is better. It allows you to prompt your user to install the barcode scanner if they do not have it. It also allows you to customize the messages. The IntentIntegrator.REQUEST_CODE constant holds the value of the request code for the onActivityResult to check for in the above if block.

IntentIntegrator intentIntegrator = new IntentIntegrator(this); // where this is activity 
intentIntegrator.initiateScan(IntentIntegrator.ALL_CODE_TYPES); // or QR_CODE_TYPES if you need to scan QR

IntentIntegrator.java

You can use lscache. It handles this for you automatically, including instances where the storage size exceeds the limit. If that happens, it begins pruning items that are the closest to their specified expiration.

From the readme:

lscache.set

Stores the value in localStorage. Expires after specified number of minutes.

Arguments
key (string)
value (Object|string)
time (number: optional)

This is the only real difference between the regular storage methods. Get, remove, etc work the same.

If you don't need that much functionality, you can simply store a time stamp with the value (via JSON) and check it for expiry.

Noteworthy, there's a good reason why local storage is left up to the user. But, things like lscache do come in handy when you need to store extremely temporary data.

For ASP.Net core Just add the following to your Startup Class:

JsonConvert.DefaultSettings = (() =>
        {
            var settings = new JsonSerializerSettings();
            settings.Converters.Add(new StringEnumConverter { AllowIntegerValues = false });
            return settings;
        });

You can remove the "bullets" by setting the "list-style-type: none;" Like

ul
{
    list-style-type: none;
}

OR

<ul class="menu custompozition4"  style="list-style-type: none;">

1. Launch Terminal
2. Type -> nano fileName
3. Paste Batch file content and save it
4. Type -> chmod +x fileName
5. It will create exe file now you can double click and it.

File name should in under double quotes. Since i am using Mac->In my case content of batch file is

cd /Users/yourName/Documents/SeleniumServer

java -jar selenium-server-standalone-3.3.1.jar -role hub

It will work for sure

I have encountered this problem and i solved mentioned problem by adding -DprofileIdEnabled=true parameter while running mvn cli command.

Please run your mvn cli command as : mvn clean install -Pdev1 -DprofileIdEnabled=true.

In addition to this solution, you don't need to remove activeByDefault settings in your POM mentioned as previouses answer.

I hope this answer solve your problem.

I think it is totally independent. Just install them, then you have the commands e.g. /usr/bin/python2.5 and /usr/bin/python2.6. Link /usr/bin/python to the one you want to use as default.

All the libraries are in separate folders (named after the version) anyway.

If you want to compile the versions manually, this is from the readme file of the Python source code:

Installing multiple versions

On Unix and Mac systems if you intend to install multiple versions of Python using the same installation prefix (--prefix argument to the configure script) you must take care that your primary python executable is not overwritten by the installation of a different version. All files and directories installed using "make altinstall" contain the major and minor version and can thus live side-by-side. "make install" also creates ${prefix}/bin/python3 which refers to ${prefix}/bin/pythonX.Y. If you intend to install multiple versions using the same prefix you must decide which version (if any) is your "primary" version. Install that version using "make install". Install all other versions using "make altinstall".

For example, if you want to install Python 2.5, 2.6 and 3.0 with 2.6 being the primary version, you would execute "make install" in your 2.6 build directory and "make altinstall" in the others.

To Wrap things up . I think most of the people which came here like me want the simplest solution possible without using any libraries and with best possible performance.

(The accepted group by method for me i think is an overkill in terms of performance. )

Here is a simple extension method using the IEqualityComparer interface which works also for null values.

Usage:

var filtered = taskList.DistinctBy(t => t.TaskExternalId).ToArray();

Extension Method Code

public static class LinqExtensions
{
    public static IEnumerable<T> DistinctBy<T, TKey>(this IEnumerable<T> items, Func<T, TKey> property)
    {
        GeneralPropertyComparer<T, TKey> comparer = new GeneralPropertyComparer<T,TKey>(property);
        return items.Distinct(comparer);
    }   
}
public class GeneralPropertyComparer<T,TKey> : IEqualityComparer<T>
{
    private Func<T, TKey> expr { get; set; }
    public GeneralPropertyComparer (Func<T, TKey> expr)
    {
        this.expr = expr;
    }
    public bool Equals(T left, T right)
    {
        var leftProp = expr.Invoke(left);
        var rightProp = expr.Invoke(right);
        if (leftProp == null && rightProp == null)
            return true;
        else if (leftProp == null ^ rightProp == null)
            return false;
        else
            return leftProp.Equals(rightProp);
    }
    public int GetHashCode(T obj)
    {
        var prop = expr.Invoke(obj);
        return (prop==null)? 0:prop.GetHashCode();
    }
}

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

I hope this will help to you.

According to the documentation for UIButton:

In iOS v7.0, all subclasses of UIView derive their behavior for tintColor from the base class. See the discussion of tintColor at the UIView level for more information.

Assuming you don't change the tintColor before grabbing the default value, you can use:

self.view.tintColor

Thanks for your replies. Here's what I did:

git gc
git gc --aggressive
git prune

That seemed to have done the trick. I started with around 10.5MB and now it's little more than 980KBs.

The way I interpreted this question is needing the subtotal value of each group of answers. Subtotaling turns out to be very easy, using PARTITION:

SUM(COUNT(0)) OVER (PARTITION BY [Grouping]) AS [MY_TOTAL]

This is what my full SQL call looks like:

SELECT MAX(GroupName) [name], MAX(AUX2)[type],  
COUNT(0) [count], SUM(COUNT(0)) OVER(PARTITION BY GroupId) AS [total]
    FROM [MyView]
  WHERE Active=1 AND Type='APP' AND Completed=1
    AND [Date] BETWEEN '01/01/2014' AND GETDATE()
    AND Id = '5b9xxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' AND GroupId IS NOT NULL
  GROUP BY AUX2, GroupId

The data returned from this looks like:

name    type    count   total
Training Group 2    Cancelation 1   52
Training Group 2    Completed   41  52
Training Group 2    No Show 6   52
Training Group 2    Rescheduled 4   52
Training Group 3    NULL        4   10535
Training Group 3    Cancelation 857 10535
Training Group 3    Completed   7923    10535
Training Group 3    No Show 292 10535
Training Group 3    Rescheduled 1459    10535
Training Group 4    Cancelation 2   27
Training Group 4    Completed   24  27
Training Group 4    Rescheduled 1   27

What is the length of str array, and with how much 0s it is ending?

Let's find out:

int main() {
  char str[] = "Hello\0";
  int length = sizeof str / sizeof str[0];
  // "sizeof array" is the bytes for the whole array (must use a real array, not
  // a pointer), divide by "sizeof array[0]" (sometimes sizeof *array is used)
  // to get the number of items in the array
  printf("array length: %d\n", length);
  printf("last 3 bytes: %02x %02x %02x\n",
         str[length - 3], str[length - 2], str[length - 1]);
  return 0;
}

All answers here seem to assume that items is an array. However, in AngularJS, it might as well be an object. In that case, neither filtering with limitTo nor array.slice will work. As one possible solution, you can convert your object to an array, if you don't mind losing the object keys. Here is an example of a filter to do just that:

myFilter.filter('obj2arr', function() {
    return function(obj) {
        if (typeof obj === 'object') {
            var arr = [], i = 0, key;
            for( key in obj ) {
                arr[i] = obj[key];
                i++;
            }
            return arr;
        }
        else {
            return obj;
        }

    };
});

Once it is an array, use slice or limitTo, as stated in other answers.

In my case I get the same error title could not resolve all dependencies for configuration

However suberror said, it was due to a linting jar not loaded with its url given saying status 502 received, I ran the deployment command again, this time it succeeded.

I found the use of the newer syntax a little bit shorter compared to the others answer. So here's my proposal:

const callback = element => element.innerHTML == 'My research'

const elements = Array.from(document.getElementsByTagName('a'))
// [a, a, a, ...]

const result = elements.filter(callback)

console.log(result)
// [a]

I think you are looking for inputstream.available(). It does not tell you whether its empty but it can give you an indication as to whether data is there to be read or not.

On OS X, I like my date to be in the format of YYYY-MM-DD HH:MM in the output for the file.

So to specify a file I would use:

stat -f "%Sm" -t "%Y-%m-%d %H:%M" [filename]

If I want to run it on a range of files, I can do something like this:

#!/usr/bin/env bash
for i in /var/log/*.out; do
  stat -f "%Sm" -t "%Y-%m-%d %H:%M" "$i"
done

This example will print out the last time I ran the sudo periodic daily weekly monthly command as it references the log files.

To add the filenames under each date, I would run the following instead:

#!/usr/bin/env bash
for i in /var/log/*.out; do
  stat -f "%Sm" -t "%Y-%m-%d %H:%M" "$i"
  echo "$i"
done

The output would was the following:

2016-40-01 16:40
/var/log/daily.out
2016-40-01 16:40
/var/log/monthly.out
2016-40-01 16:40
/var/log/weekly.out

Unfortunately I'm not sure how to prevent the line break and keep the file name appended to the end of the date without adding more lines to the script.

PS - I use #!/usr/bin/env bash as I'm a Python user by day, and have different versions of bash installed on my system instead of #!/bin/bash

If you are using Xcode 6 and designing for iOS 8, none of these solutions are correct. To get your iPhone-only views to be sized correctly, don't turn off size classes, don't turn off inferred metrics, and don't set constraints (yet). Instead, use the size class control, which is an easy to miss text button at the bottom of Interface Builder that initially reads "wAny hAny".

Click the button, and choose Compact Width, Regular Height. This resize your views and cover all iPhone portrait orientations. Apple's docs here: https://developer.apple.com/library/ios/recipes/xcode_help-IB_adaptive_sizes/chapters/SelectingASizeClass.html or search on "Selecting a Size Class in Interface Builder"

I had a similar issue that was resolved by unchecking the option in java advanced security for "Use SSL 2.0 compatible ClientHello format.

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

I was asking the same too. Another solution is you could overload your method:

void remove_id(EmployeeClass);
void remove_id(ProductClass);
void remove_id(DepartmentClass);

in the call the argument will fit accordingly the object you pass. but then you will have to repeat yourself

void remove_id(EmployeeClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(ProductClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(DepartmentClass _obj) {
    int saveId = _obj->id;
    ...
};

Fake IE10 to install Visual Studio 2013

Visual Studio 2013 requires Internet Explorer 10. If you try to install it on Windows 7 with IE8 you get the following error This version of Visual Studio requires Internet Explorer 10”. The value that the VS 2013 installer checks is svcVersion in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorerkey on 32-bit Windows and HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer on 64-bit Windows. Any value >= 10.0.0.0 makes the installer happy.

Looking at the bottom of your wp-config.php file in the wordpress root directory will let you find something like this:

if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

For an example file have a look here:
http://core.trac.wordpress.org/browser/trunk/wp-config-sample.php

You can make use of this constant called ABSPATH in other places of your wordpress scripts and in most cases it should point to your wordpress root directory.

Method 1 (Preferred):

if not a :

Method 2 :

Method 3:

  print ("Empty")

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

If you have control over the request, you could set the content type to binary/octet-stream. This allows to query for parameters without consuming the input stream.

However, this might be specific to some application servers. I only tested tomcat, jetty seems to behave the same way according to https://stackoverflow.com/a/11434646/957103.

I had to quit Intellij and remove the .idea folder (I stashed it first, just in case). I then re-opened the project and that worked for me. Don't forget to save your configuration (e.g. debug / run configurations) before that, because they will also be deleted.

This is a never ending story that reflect the limits (an myth) of "interoperability and portability over all".

What the program should return to indicate "success" should be defined by who is receiving the value (the Operating system, or the process that invoked the program) not by a language specification.

But programmers likes to write code in "portable way" and hence they invent their own model for the concept of "operating system" defining symbolic values to return.

Now, in a many-to-many scenario (where many languages serve to write programs to many system) the correspondence between the language convention for "success" and the operating system one (that no one can grant to be always the same) should be handled by the specific implementation of a library for a specific target platform.

But - unfortunatly - these concept where not that clear at the time the C language was deployed (mainly to write the UNIX kernel), and Gigagrams of books where written by saying "return 0 means success", since that was true on the OS at that time having a C compiler.

From then on, no clear standardization was ever made on how such a correspondence should be handled. C and C++ has their own definition of "return values" but no-one grant a proper OS translation (or better: no compiler documentation say anything about it). 0 means success if true for UNIX - LINUX and -for independent reasons- for Windows as well, and this cover 90% of the existing "consumer computers", that - in the most of the cases - disregard the return value (so we can discuss for decades, bu no-one will ever notice!)

Inside this scenario, before taking a decision, ask these questions: - Am I interested to communicate something to my caller about my existing? (If I just always return 0 ... there is no clue behind the all thing) - Is my caller having conventions about this communication ? (Note that a single value is not a convention: that doesn't allow any information representation)

If both of this answer are no, probably the good solution is don't write the main return statement at all. (And let the compiler to decide, in respect to the target is working to).

If no convention are in place 0=success meet the most of the situations (and using symbols may be problematic, if they introduce a convention).

If conventions are in place, ensure to use symbolic constants that are coherent with them (and ensure convention coherence, not value coherence, between platforms).

If you want to use it every time add the path of adb to your system variables: enter to cmd (command prompt) and write the following:

echo %PATH%

this command will show you what it was before you will add adb path

setx PATH "%PATH%;C:\Program Files\android-sdk-windows\platform-tools"

be careful the path that you want to add if it contains double quote

after you restart your cmd rewrite:

echo %PATH%

you will find that the path is added

PS: if you just want to add the path to cmd just to this session you can use:

set PATH=%PATH%;C:\Program Files\android-sdk-windows\platform-tools

date.ToString("o") // The Round-trip ("O", "o") Format Specifier
date.ToString("s") // The Sortable ("s") Format Specifier, conforming to ISO86801

If you need get table from string with delimiters:

SET @str = 'function1;function2;function3;function4;aaa;bbbb;nnnnn';
SET @delimeter = ';';
SET @sql_statement = CONCAT('SELECT '''
                ,REPLACE(@str, @delimeter, ''' UNION ALL SELECT ''')
                ,'''');
SELECT @sql_statement;
SELECT 'function1' UNION ALL SELECT 'function2' UNION ALL SELECT 'function3' UNION ALL SELECT 'function4' UNION ALL SELECT 'aaa' UNION ALL SELECT 'bbbb' UNION ALL SELECT 'nnnnn'

The easiest solution would be to use Wireshark and trace the HTTP tcp flow.

You can accomplish this using man-in-the-middle techniques with dynamic SSL generation. Take a look at mitmproxy - it's a Python based, SSL-capable MITM proxy.

I'm assuming you want to add this row to the <tbody> element, and simply using append() on the <table> will insert the <tr> outside the <tbody>, with perhaps undesirable results.

$('a').click(function() {

Sometimes Java generics just doesn't let you do what you want to, and you need to effectively tell the compiler that what you're doing really will be legal at execution time.

I usually find this a pain when I'm mocking a generic interface, but there are other examples too. It's usually worth trying to work out a way of avoiding the warning rather than suppressing it (the Java Generics FAQ helps here) but sometimes even if it is possible, it bends the code out of shape so much that suppressing the warning is neater. Always add an explanatory comment in that case!

The same generics FAQ has several sections on this topic, starting with "What is an "unchecked" warning?" - it's well worth a read.

You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

List(1,2,3) :+ 4

Results in List[Int] = List(1, 2, 3, 4)

Note that this operation has a complexity of O(n). If you need this operation frequently, or for long lists, consider using another data type (e.g. a ListBuffer).

The simple solution just do npm link gulp

There should be no semicolon here:

class WordGame;

...but there should be one at the end of your class definition:

...
private:
    string theWord;
}; // <-- Semicolon should be at the end of your class definition

There exists two daemons that detect these events:

ifplugd and netplugd

Since the onItemClickLitener() will itself provide you the index of the selected item, you can simply do a getItemAtPosition(i).toString(). The code snippet is given below :-

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            String s = listView.getItemAtPosition(i).toString();

            Toast.makeText(activity.getApplicationContext(), s, Toast.LENGTH_LONG).show();
            adapter.dismiss(); // If you want to close the adapter
        }
    });

On the method above, the i parameter actually gives you the position of the selected item.

DECLARE @theDate DATETIME
SET @theDate = '2010-01-01'

Then change your query to use this logic:

AND 
(
    tblWO.OrderDate > DATEADD(MILLISECOND, -1, @theDate) 
    AND tblWO.OrderDate < DATEADD(DAY, 1, @theDate)
)

I'm going to say that it is not possible to completely prevent screen/video capture of any android app through supported means. But if you only want to block it for normal android devices, the SECURE FLAG is substantial.

1) The secure flag does block both normal screenshot and video capture.

Also documentation at this link says that

Window flag: treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays.

Above solution will surely prevent applications from capturing Video of your app

See the answer here.

2) There are alternative means of capturing screen content.

It may be possible to capture the screen of another app on a rooted device or through using the SDK,

which both offer little to no chance of you either blocking it or receiving notification of it.

For example: there exists software to mirror your phone screen to your computer via the SDK and so screen capture software could be used there, undiscoverable by your app.

See the answer here.

getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);

To get last month's first date:

select DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE())-1, 0) LastMonthFirstDate                                                                

To get last month's last date:

select DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) LastMonthEndDate

One option from dplyr 1.0.0 could be:

DF %>%
 rowwise() %>%
 mutate(row_max = names(.)[which.max(c_across(everything()))])

     V1    V2    V3 row_max
  <dbl> <dbl> <dbl> <chr>  
1     2     7     9 V3     
2     8     3     6 V1     
3     1     5     4 V2     

Sample data:

DF <- structure(list(V1 = c(2, 8, 1), V2 = c(7, 3, 5), V3 = c(9, 6, 
4)), class = "data.frame", row.names = c(NA, -3L))

You can use an echo with a pipe to avoid prompts or confirmation.

echo "This is the body" | mail -s "This is the subject" [email protected]

You can use the following code:

playButton = (Button) findViewById(R.id.play);
playButton.setVisibility(View.VISIBLE);
playButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        //when play is clicked show stop button and hide play button
        playButton.setVisibility(View.GONE);
        stopButton.setVisibility(View.VISIBLE);
    }
});

Change App Package Name easily using change_app_package_name package

just add the above package in dev dependencies

dev_dependencies:
  flutter_test:
    sdk: flutter
  change_app_package_name: ^0.1.2

and run the following command, replace "com.new.package.name" with your new package name

flutter pub run change_app_package_name:main com.new.package.name

Package Link on Pub Dev

Well,

you can also use a third party library like Aspose.

This library has the benefit that it does not require Excel to be installed on your machine which would be ideal in your case.

you can use the following code to check whether

{% if var is defined %}

var is variable is SET

{% endif %}

The terminology is a bit confusing indeed, but both javax.net.ssl.keyStore and javax.net.ssl.trustStore are used to specify which keystores to use, for two different purposes. Keystores come in various formats and are not even necessarily files (see this question), and keytool is just a tool to perform various operations on them (import/export/list/...).

The javax.net.ssl.keyStore and javax.net.ssl.trustStore parameters are the default parameters used to build KeyManagers and TrustManagers (respectively), then used to build an SSLContext which essentially contains the SSL/TLS settings to use when making an SSL/TLS connection via an SSLSocketFactory or an SSLEngine. These system properties are just where the default values come from, which is then used by SSLContext.getDefault(), itself used by SSLSocketFactory.getDefault() for example. (All of this can be customized via the API in a number of places, if you don't want to use the default values and that specific SSLContexts for a given purpose.)

The difference between the KeyManager and TrustManager (and thus between javax.net.ssl.keyStore and javax.net.ssl.trustStore) is as follows (quoted from the JSSE ref guide):

TrustManager: Determines whether the remote authentication credentials (and thus the connection) should be trusted.

KeyManager: Determines which authentication credentials to send to the remote host.

(Other parameters are available and their default values are described in the JSSE ref guide. Note that while there is a default value for the trust store, there isn't one for the key store.)

Essentially, the keystore in javax.net.ssl.keyStore is meant to contain your private keys and certificates, whereas the javax.net.ssl.trustStore is meant to contain the CA certificates you're willing to trust when a remote party presents its certificate. In some cases, they can be one and the same store, although it's often better practice to use distinct stores (especially when they're file-based).

Can also use the dayjs relativeTime plugin to solve this.

import * as dayjs from 'dayjs';
import * as relativeTime from 'dayjs/plugin/relativeTime';

dayjs.extend(relativeTime);
dayjs(dayjs('1990')).fromNow(); // x years ago

Yet another version of the same kind of control. It has similar functionality as the others, but it adds:

1. Touch support (drag/pinch)
2. The image can be deleted (normally, the Image control locks the image on disk, so you cannot delete it).
3. An inner border child, so the panned image doesn't overlap the border. In case of borders with rounded rectangles, look for ClippedBorder classes.

Usage is simple:

<Controls:ImageViewControl ImagePath="{Binding ...}" />

And the code:

public class ImageViewControl : Border
{
    private Point origin;
    private Point start;
    private Image image;

    public ImageViewControl()
    {
        ClipToBounds = true;

    }

        target.OnImagePathChanged(oldImagePath, newImagePath);

You can try viewport units (CSS3):

canvas { 
  height: 100vh; 
  width: 100vw; 
  display: block;
}

Try using the not() method instead of the :not() selector.

$(".content a").click(function() {
    $(".content a").not(this).hide("slow");
});

You can either scan an entire line:

Scanner s = new Scanner(System.in);
String str = s.nextLine();

Or you can read a single char, given you know what encoding you're dealing with:

char c = (char) System.in.read();

To my knowledge there is no difference between NUMERIC and DECIMAL data types. They are synonymous to each other and either one can be used. DECIMAL and NUMERIC data types are numeric data types with fixed precision and scale.

Edit:

Speaking to a few collegues maybe its has something to do with DECIMAL being the ANSI SQL standard and NUMERIC being one Mircosoft prefers as its more commonly found in programming languages. ...Maybe ;)

I use this:

function strip_word_html($text, $allowed_tags = '<a><ul><li><b><i><sup><sub><em><strong><u><br><br/><br /><p><h2><h3><h4><h5><h6>')
{
    mb_regex_encoding('UTF-8');
    //replace MS special characters first
    $search = array('/&lsquo;/u', '/&rsquo;/u', '/&ldquo;/u', '/&rdquo;/u', '/&mdash;/u');
    $replace = array('\'', '\'', '"', '"', '-');
    $text = preg_replace($search, $replace, $text);
    //make sure _all_ html entities are converted to the plain ascii equivalents - it appears
    //in some MS headers, some html entities are encoded and some aren't
    //$text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');
    //try to strip out any C style comments first, since these, embedded in html comments, seem to
    //prevent strip_tags from removing html comments (MS Word introduced combination)
    if(mb_stripos($text, '/*') !== FALSE){
        $text = mb_eregi_replace('#/\*.*?\*/#s', '', $text, 'm');
    }
    //introduce a space into any arithmetic expressions that could be caught by strip_tags so that they won't be
    //'<1' becomes '< 1'(note: somewhat application specific)
    $text = preg_replace(array('/<([0-9]+)/'), array('< $1'), $text);
    $text = strip_tags($text, $allowed_tags);
    //eliminate extraneous whitespace from start and end of line, or anywhere there are two or more spaces, convert it to one
    $text = preg_replace(array('/^\s\s+/', '/\s\s+$/', '/\s\s+/u'), array('', '', ' '), $text);
    //strip out inline css and simplify style tags
    $search = array('#<(strong|b)[^>]*>(.*?)</(strong|b)>#isu', '#<(em|i)[^>]*>(.*?)</(em|i)>#isu', '#<u[^>]*>(.*?)</u>#isu');
    $replace = array('<b>$2</b>', '<i>$2</i>', '<u>$1</u>');
    $text = preg_replace($search, $replace, $text);
    //on some of the ?newer MS Word exports, where you get conditionals of the form 'if gte mso 9', etc., it appears
    //that whatever is in one of the html comments prevents strip_tags from eradicating the html comment that contains
    //some MS Style Definitions - this last bit gets rid of any leftover comments */
    $num_matches = preg_match_all("/\<!--/u", $text, $matches);
    if($num_matches){
        $text = preg_replace('/\<!--(.)*--\>/isu', '', $text);
    }
    $text = preg_replace('/(<[^>]+) style=".*?"/i', '$1', $text);
return $text;
}

First of all you do not need a .py.

If you have a file a.py and inside you have some functions:

def b():
  # Something
  return 1

def c():
  # Something
  return 2

And you want to import them in z.py you have to write

from a import b, c

Sadly this happens to me quite regularly as well and I use git stash if I realized my mistake before git commit and use git cherry-pick otherwise, both commands are explained pretty well in other answers

I want to add a clarification for git checkout targetBranch: this command will only preserve your working directory and staged snapshot if targetBranch has the same history as your current branch

If you haven't already committed your changes, just use git checkout to move to the new branch and then commit them normally

@Amber's statement is not false, when you move to a newBranch,git checkout -b newBranch, a new pointer is created and it is pointing to the exact same commit as your current branch.
In fact, if you happened to have an another branch that shares history with your current branch (both point at the same commit) you can "move your changes" by git checkout targetBranch

However, usually different branches means different history, and Git will not allow you to switch between these branches with a dirty working directory or staging area. in which case you can either do git checkout -f targetBranch (clean and throwaway changes) or git stage + git checkout targetBranch (clean and save changes), simply running git checkout targetBranch will give an error:

error: Your local changes to the following files would be overwritten by checkout: ... Please commit your changes or stash them before you switch branches. Aborting

This is actually reasonably easy. You can programatically detect skin tones - and porn images tend to have a lot of skin. This will create false positives but if this is a problem you can pass images so detected through actual moderation. This not only greatly reduces the the work for moderators but also gives you lots of free porn. It's win-win.

#!python    
import os, glob
from PIL import Image

def get_skin_ratio(im):
    im = im.crop((int(im.size[0]*0.2), int(im.size[1]*0.2), im.size[0]-int(im.size[0]*0.2), im.size[1]-int(im.size[1]*0.2)))
    skin = sum([count for count, rgb in im.getcolors(im.size[0]*im.size[1]) if rgb[0]>60 and rgb[1]<(rgb[0]*0.85) and rgb[2]<(rgb[0]*0.7) and rgb[1]>(rgb[0]*0.4) and rgb[2]>(rgb[0]*0.2)])
    return float(skin)/float(im.size[0]*im.size[1])

for image_dir in ('porn','clean'):
    for image_file in glob.glob(os.path.join(image_dir,"*.jpg")):
        skin_percent = get_skin_ratio(Image.open(image_file)) * 100
        if skin_percent>30:
            print "PORN {0} has {1:.0f}% skin".format(image_file, skin_percent)
        else:
            print "CLEAN {0} has {1:.0f}% skin".format(image_file, skin_percent)

This code measures skin tones in the center of the image. I've tested on 20 relatively tame "porn" images and 20 completely innocent images. It flags 100% of the "porn" and 4 out of the 20 of the clean images. That's a pretty high false positive rate but the script aims to be fairly cautious and could be further tuned. It works on light, dark and Asian skin tones.

It's main weaknesses with false positives are brown objects like sand and wood and of course it doesn't know the difference between "naughty" and "nice" flesh (like face shots).

Weakness with false negatives would be images without much exposed flesh (like leather bondage), painted or tattooed skin, B&W images, etc.

source code and sample images

To be safe you may want to use both...

input[readonly], input[readonly="readonly"] {
    /*styling info here*/
}

The readonly attribute is a "boolean attribute", which can be either blank or "readonly" (the only valid values). http://www.whatwg.org/specs/web-apps/current-work/#boolean-attribute

If you are using something like jQuery's .prop('readonly', true) function, you'll end up needing [readonly], whereas if you are using .attr("readonly", "readonly") then you'll need [readonly="readonly"].

Correction: You only need to use input[readonly]. Including input[readonly="readonly"] is redundant. See https://stackoverflow.com/a/19645203/1766230

Below is the right code. Include JS files in following manner:

$(document).ready(function() {_x000D_
  $(function() {_x000D_
    $('#datetimepicker6').datetimepicker();_x000D_
    $('#datetimepicker7').datetimepicker({_x000D_
      useCurrent: false //Important! See issue #1075_x000D_
    });_x000D_
    $("#datetimepicker6").on("dp.change", function(e) {_x000D_
      $('#datetimepicker7').data("DateTimePicker").minDate(e.date);_x000D_
    });_x000D_
    $("#datetimepicker7").on("dp.change", function(e) {_x000D_
      $('#datetimepicker6').data("DateTimePicker").maxDate(e.date);_x000D_
    });_x000D_

API is like the building blocks of some puzzling game that a child plays with to join blocks in different shapes and build something they can think of.

SDK, on the other hand, is a proper workshop where all of the development tools are available, rather than pre-shaped building blocks. In a workshop you have the actual tools and you are not limited to blocks, and can therefore make your own blocks, or can create something without any blocks to begin with.

coding without an SDK or API is like making everything from scratch without a workshop - you have to even make your own tools

If you are worried at all about speed, you should instead use:

mag = np.sqrt(x.dot(x))

Here are some benchmarks:

>>> import timeit
>>> timeit.timeit('np.linalg.norm(x)', setup='import numpy as np; x = np.arange(100)', number=1000)
0.0450878
>>> timeit.timeit('np.sqrt(x.dot(x))', setup='import numpy as np; x = np.arange(100)', number=1000)
0.0181372

EDIT: The real speed improvement comes when you have to take the norm of many vectors. Using pure numpy functions doesn't require any for loops. For example:

In [1]: import numpy as np

In [2]: a = np.arange(1200.0).reshape((-1,3))

In [3]: %timeit [np.linalg.norm(x) for x in a]
100 loops, best of 3: 4.23 ms per loop

In [4]: %timeit np.sqrt((a*a).sum(axis=1))
100000 loops, best of 3: 18.9 us per loop

In [5]: np.allclose([np.linalg.norm(x) for x in a],np.sqrt((a*a).sum(axis=1)))
Out[5]: True

SAP is notoriously bad at making these downloads available... or in an easily accessible location so hopefully this link still works by the time you read this answer.

Here is another way:

#include <stdlib.h>
int main()
{
    char* inStr = "123.4567";         //the number we want to convert
    char* endptr;                     //unused char ptr for strtod

    char* loc = strchr(inStr, '.');
    long mantissa = strtod(loc+1, endptr);
    long whole = strtod(inStr, endptr);

    printf("whole: %d \n", whole);     //whole number portion
    printf("mantissa: %d", mantissa);  //decimal portion

}

Output:

whole: 123 
mantissa: 4567

Firstly, try / except are not functions, but statements.

To convert a string (or any other type that can be converted) to an integer in Python, simply call the int() built-in function. int() will raise a ValueError if it fails and you should catch this specifically:

In Python 2.x:

>>> for value in '12345', 67890, 3.14, 42L, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print '%s as an int is %d' % (str(value), int(value))
...     except ValueError as ex:
...         print '"%s" cannot be converted to an int: %s' % (value, ex)
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

In Python 3.x

the syntax has changed slightly:

>>> for value in '12345', 67890, 3.14, 42, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print('%s as an int is %d' % (str(value), int(value)))
...     except ValueError as ex:
...         print('"%s" cannot be converted to an int: %s' % (value, ex))
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

You can also see the error in the Build window by clicking on the toggle button.

        on b.common = c.common

If you're using Dapper.SimpleSave:

 //no safety checks
 public static int Create<T>(object param)
    {
        using (SqlConnection conn = new SqlConnection(GetConnectionString()))
        {
            conn.Open();
            conn.Create<T>((T)param);
            return (int) (((T)param).GetType().GetProperties().Where(
                    x => x.CustomAttributes.Where(
                        y=>y.AttributeType.GetType() == typeof(Dapper.SimpleSave.PrimaryKeyAttribute).GetType()).Count()==1).First().GetValue(param));
        }
    }

$date = new DateTime(date("Y-m-d"));
$date->modify('+7 day');
$tomorrowDATE = $date->format('Y-m-d');

To remove 'whitespace',

import re
t = """
\n\t<p>&nbsp;</p>\n\t<p>&nbsp;</p>\n\t<p>&nbsp;</p>\n\t<p>&nbsp;</p>\n\t<p>
"""
pat = re.compile(r'[\t\n]')
print(pat.sub("", t))

Personally I find it appalling that typescript does not allow an endpoint definition to specify the type of the object being received. As it appears that this is indeed the case, I would do what I have done with other languages, and that is that I would separate the JSON object from the class definition, and have the class definition use the JSON object as its only data member.

I despise boilerplate code, so for me it is usually a matter of getting to the desired result with the least amount of code while preserving type.

Consider the following JSON object structure definitions - these would be what you would receive at an endpoint, they are structure definitions only, no methods.

interface IAddress {
    street: string;
    city: string;
    state: string;
    zip: string;
}

interface IPerson {
    name: string;
    address: IAddress;
}

If we think of the above in object oriented terms, the above interfaces are not classes because they only define a data structure. A class in OO terms defines data and the code that operates on it.

So we now define a class that specifies data and the code that operates on it...

class Person {
    person: IPerson;

    constructor(person: IPerson) {
        this.person = person;
    }

    // accessors
    getName(): string {
        return person.name;
    }

    getAddress(): IAddress {
        return person.address;
    }

    // You could write a generic getter for any value in person, 
    // no matter how deep, by accepting a variable number of string params

    // methods
    distanceFrom(address: IAddress): float {
        // Calculate distance from the passed address to this persons IAddress
        return 0.0;
    }
}

And now we can simply pass in any object conforming to the IPerson structure and be on our way...

   Person person = new Person({
            name: "persons name",
            address: {
                street: "A street address",
                city: "a city",
                state: "a state",
                zip: "A zipcode"
            }
        });

In the same fashion we can now process the object received at your endpoint with something along the lines of...

Person person = new Person(req.body);    // As in an object received via a POST call

person.distanceFrom({ street: "Some street address", etc.});

This is much more performant and uses half the memory of copying the data, while significantly reducing the amount of boilerplate code you must write for each entity type. It simply relies on the type safety provided by TypeScript.

To add useful information to the conversation, I came across 404 errors for my bundles in the deployment (it was fine in the local dev environment).

For the bundle names, I including version numbers like such:

bundles.Add(new ScriptBundle("~/bundles/jquerymobile.1.4.3").Include(
...
);

On a whim, I removed all the dots and all was working magically again:

bundles.Add(new ScriptBundle("~/bundles/jquerymobile143").Include(
...
);

Hope that helps someone save some time and frustration.

Be aware the time window between you make check and the moment you try to make connection some process may take the port - classical TOCTOU. Why don't you just try to connect? If it fails then you know the port is not available.

I used this in my vb code for the return value of a function:

If obj <> Nothing Then Return obj.ToString() Else Return "" End If

It is not possible. §2.3 says that "." is an unreserved character and that "URIs that differ in the replacement of an unreserved character with its corresponding percent-encoded US-ASCII octet are equivalent". Therefore, /%2E%2E/ is the same as /../, and that will get normalized away.

(This is a combination of an answer by bobince and a comment by slowpoison.)

exampleData=

        const json1 = [
            {id: 1, test: 1},
            {id: 2, test: 2},
            {id: 3, test: 3},
            {id: 4, test: 4},
            {id: 5, test: 5}
        ];

        const json2 = [
            {id: 3, test: 6},
            {id: 4, test: 7},
            {id: 5, test: 8},
            {id: 6, test: 9},
            {id: 7, test: 10}
        ];

example1=

        const finalData1 = json1.concat(json2).reduce(function (index, obj) {
            index[obj.id] = Object.assign({}, obj, index[obj.id]);
            return index;
        }, []).filter(function (res, obj) {
            return obj;
        });

example2=

        let hashData = new Map();

        json1.concat(json2).forEach(function (obj) {
            hashData.set(obj.id, Object.assign(hashData.get(obj.id) || {}, obj))
        });

        const finalData2 = Array.from(hashData.values());

I recommend second example , it is faster.

You just have to post the data. and Using jquery ajax function set parameters. Here is an example.

<script>
        $(function () {

            $('form').on('submit', function (e) {

                e.preventDefault();

                $.ajax({
                    type: 'post',
                    url: 'your_complete url',
                    data: $('form').serialize(),
                    success: function (response) {
                        //$('form')[0].reset();
                       // $("#feedback").text(response);
                        if(response=="True") {
                            $('form')[0].reset();
                            $("#feedback").text("Your information has been stored.");
                        }
                        else
                            $("#feedback").text(" Some Error has occured Errror !!! ID duplicate");
                    }
                });

            });

        });
    </script>

Also add the key "StartingMonthColumn" in App.config that you run application from, for example in the App.config of the test project.

You can create a custom loading screen instead of splash screen. if you show a splash screen for 10 sec, it's not a good idea for user experience. So it's better to add a custom loading screen. For a custom loading screen you may need some different images to make that feel like a gif. after that add the images in the res folder and make a class like this :-

public class LoadingScreen {private ImageView loading;

LoadingScreen(ImageView loading) {
    this.loading = loading;
}

public void setLoadScreen(){
    final Integer[] loadingImages = {R.mipmap.loading_1, R.mipmap.loading_2, R.mipmap.loading_3, R.mipmap.loading_4};
    final Handler loadingHandler = new Handler();
    Runnable runnable = new Runnable() {
        int loadingImgIndex = 0;
        public void run() {
            loading.setImageResource(loadingImages[loadingImgIndex]);
            loadingImgIndex++;
            if (loadingImgIndex >= loadingImages.length)
                loadingImgIndex = 0;
            loadingHandler.postDelayed(this, 500);
        }
    };
    loadingHandler.postDelayed(runnable, 500);
}}

In your MainActivity, you can pass a to the LoadingScreen class like this :-

private ImageView loadingImage;

Don't forget to add an ImageView in activity_main. After that call the LoadingScreen class like this;

LoadingScreen loadingscreen = new LoadingScreen(loadingImage);
loadingscreen.setLoadScreen();

I hope this will help you

To implement you need use Typeface go through with sample below

Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/Roboto/Roboto-Regular.ttf");
for (View view : allViews)
{
   if (view instanceof TextView) 
   {
      TextView textView = (TextView) view;
      textView.setTypeface(typeface);
      }
   }
}

You should put all your words into some kind of Collection or List and then call it like this:

var searchFor = new List<string>();
searchFor.Add("pineapple");
searchFor.Add("mango");

bool containsAnySearchString = searchFor.Any(word => compareString.Contains(word));

If you need to make a case or culture independent search you should call it like this:

bool containsAnySearchString = 
   searchFor.Any(word => compareString.IndexOf
     (word, StringComparison.InvariantCultureIgnoreCase >= 0);

RESTful does not recommend using verbs in URL's /cars/search is not restful. The right way to filter/search/paginate your API's is through Query Parameters. However there might be cases when you have to break the norm. For example, if you are searching across multiple resources, then you have to use something like /search?q=query

You can go through http://saipraveenblog.wordpress.com/2014/09/29/rest-api-best-practices/ to understand the best practices for designing RESTful API's

Just to add on to the topic of for in/for/$.each, I added a jsperf test case for using $.each vs for in: http://jsperf.com/each-vs-for-in/2

Different browsers/versions handle it differently, but it seems $.each and straight out for in are the cheapest options performance-wise.

If you're using for in to iterate through an associative array/object, knowing what you're after and ignoring everything else, use $.each if you use jQuery, or just for in (and then a break; once you've reached what you know should be the last element)

If you're iterating through an array to perform something with each key pair in it, should use the hasOwnProperty method if you DON'T use jQuery, and use $.each if you DO use jQuery.

Always use for(i=0;i<o.length;i++) if you don't need an associative array though... lol chrome performed that 97% faster than a for in or $.each

As stated in the relevant RxJS documentation, the .subscribe() method can take a third argument that is called on completion if there are no errors.

For reference:

1. [onNext] (Function): Function to invoke for each element in the observable sequence.
2. [onError] (Function): Function to invoke upon exceptional termination of the observable sequence.
3. [onCompleted] (Function): Function to invoke upon graceful termination of the observable sequence.

Therefore you can handle your routing logic in the onCompleted callback since it will be called upon graceful termination (which implies that there won't be any errors when it is called).

this.httpService.makeRequest()
    .subscribe(
      result => {
        // Handle result
        console.log(result)
      },
      error => {
        this.errors = error;
      },
      () => {
        // 'onCompleted' callback.
        // No errors, route to new page here
      }
    );

As a side note, there is also a .finally() method which is called on completion regardless of the success/failure of the call. This may be helpful in scenarios where you always want to execute certain logic after an HTTP request regardless of the result (i.e., for logging purposes or for some UI interaction such as showing a modal).

Rx.Observable.prototype.finally(action)

Invokes a specified action after the source observable sequence terminates gracefully or exceptionally.

For instance, here is a basic example:

import { Observable } from 'rxjs/Rx';
import 'rxjs/add/operator/finally';

// ...

this.httpService.getRequest()
    .finally(() => {
      // Execute after graceful or exceptionally termination
      console.log('Handle logging logic...');
    })
    .subscribe (
      result => {
        // Handle result
        console.log(result)
      },
      error => {
        this.errors = error;
      },
      () => {
        // No errors, route to new page
      }
    );

also, I had this problem but the bib file wouldn't recompile. I removed the problem, which was an underscore in the note field, and compiled the tex file again, but kept getting the same errors. In the end I del'd the compiled bib file (.bbl I think) and it worked fine. I had to escape the _ using a backslash.

Collections.synchronizedMap() guarantees that each atomic operation you want to run on the map will be synchronized.

Running two (or more) operations on the map however, must be synchronized in a block. So yes - you are synchronizing correctly.

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

The question is what's the difference between

char *name

which points to a constant string literal, and

const char *cname

I.e. given

char *name = "foo";

and

const char *cname = "foo";

There is not much difference between the 2 and both can be seen as correct. Due to the long legacy of C code, the string literals have had a type of char[], not const char[], and there are lots of older code that likewise accept char * instead of const char *, even when they do not modify the arguments.

The principal difference of the 2 in general is that *cname or cname[n] will evaluate to lvalues of type const char, whereas *name or name[n] will evaluate to lvalues of type char, which are modifiable lvalues. A conforming compiler is required to produce a diagnostics message if target of the assignment is not a modifiable lvalue; it need not produce any warning on assignment to lvalues of type char:

name[0] = 'x'; // no diagnostics *needed*
cname[0] = 'x'; // a conforming compiler *must* produce a diagnostic message

The compiler is not required to stop the compilation in either case; it is enough that it produces a warning for the assignment to cname[0]. The resulting program is not a correct program. The behaviour of the construct is undefined. It may crash, or even worse, it might not crash, and might change the string literal in memory.

With using Smart-IP.net Geo-IP API. For example, by using jQuery:

$(document).ready( function() {
    $.getJSON( "http://smart-ip.net/geoip-json?callback=?",
        function(data){
            alert( data.host);
        }
    );
});

<script> 
    function show() { 
        if(document.getElementById('benefits').style.display=='none') { 
            document.getElementById('benefits').style.display='block'; 
        } 
        return false;
    } 
    function hide() { 
        if(document.getElementById('benefits').style.display=='block') { 
            document.getElementById('benefits').style.display='none'; 
        } 
        return false;
    }   
</script> 


 <div id="opener"><a href="#1" name="1" onclick="return show();">click here</a></div> 
    <div id="benefits" style="display:none;">some input in here plus the close button 
           <div id="upbutton"><a onclick="return hide();">click here</a></div> 
    </div> 

with open('file.txt', 'r') as searchfile:
    for line in searchfile:
        if 'searchphrase' in line:
            print line

With apologies to senderle who I blatantly copied.

Try adding ?wmode=transparent to the end of the URL. Worked for me.

You could create a class that extends the Tkinter Button class, that will be specialised to close your window by associating the destroy method to its command attribute:

from tkinter import *

class quitButton(Button):
    def __init__(self, parent):
        Button.__init__(self, parent)
        self['text'] = 'Good Bye'
        # Command to close the window (the destory method)
        self['command'] = parent.destroy
        self.pack(side=BOTTOM)

root = Tk()
quitButton(root)
mainloop()

This is the output:

And the reason why your code did not work before:

def close_window (): 
    # root.destroy()
    window.destroy()

I have a slight feeling you might got the root from some other place, since you did window = tk().

When you call the destroy on the window in the Tkinter means destroying the whole application, as your window (root window) is the main window for the application. IMHO, I think you should change your window to root.

from tkinter import *

def close_window():
    root.destroy()  # destroying the main window

root = Tk()
frame = Frame(root)
frame.pack()

button = Button(frame)
button['text'] ="Good-bye."
button['command'] = close_window
button.pack()

mainloop()

As already pointed out by @snishalaka, you can increase the number of inotify watchers.

However, I think the default number is high enough and is only reached when processes are not cleaned up properly. Hence, I simply restarted my computer as proposed on a related github issue and the error message was gone.

You can use the filter_input() function with FILTER_VALIDATE_INT and FILTER_NULL_ON_FAILURE to filter only integer values out of the $_GET variable. Works pretty accurately! :)

Check out my question here: How to check whether a variable in $_GET Array is an integer?

The "cd" command changes the directory, but not what drive you are working with. So when you go "cd d:\temp", you are changing the D drive's directory to temp, but staying in the C drive.

Execute these two commands:

D:
cd temp

That will get you the results you want.

I think you may need to stringify the data using JSON.stringify.

 var data = JSON.stringify({ 
                 'StrContactDetails': Details,
                 'IsPrimary':true
               });

$.ajax({
        type: "POST",
        url: @url.Action("Dhp","SaveEmergencyContact"),
        data: data,
        success: function(){},
        contentType: 'application/json'
    });

So the controller method would look like,

public ActionResult SaveEmergencyContact(string  StrContactDetails, bool IsPrimary)

This is because chrome handles the mailto in different way. You can go to chrome://settings/handlers and make sure that which is the default handler. In your case it will be none (i.e. not listed). Now go to gmail.com. You should see something like this when you click on the button beside the bookmark button.

If you wish to open all email links through gmail then set "Use Gmail". Now when you click on mailto button, chrome will automatically opens in gmail.

This will help you

EDIT

using echo '<pre>'; is useless, but var_export($var); will do the thing which you are expecting.

I was getting the same error while the jar was present. No solution worked. What worked was deleting the jar from the file system (from .m2 directory) and then cleaning the maven project.

The pip's proxy parameter is, according to pip --help, in the form scheme://[user:passwd@]proxy.server:port

You should use the following:

pip install --proxy http://user:password@proxyserver:port TwitterApi

Also, the HTTP_PROXY env var should be respected.

Note that in earlier versions (couldn't track down the change in the code, sorry, but the doc was updated here), you had to leave the scheme:// part out for it to work, i.e. pip install --proxy user:password@proxyserver:port

You can use the | operator to combine querysets directly without needing Q objects:

result = Item.objects.filter(item.creator = owner) | Item.objects.filter(item.moderated = False)

(edit - I was initially unsure if this caused an extra query but @spookylukey pointed out that lazy queryset evaluation takes care of that)

You can use a TreeMap data structure. TreeMap is implemented as a red black tree, which is a self-balancing binary search tree.

DECLARE @result varchar(1000)

SELECT @result = ISNULL(@result, '') + StudentId + ',' FROM Student WHERE condition = xyz

select substring(@result, 0, len(@result) - 1) --trim extra "," at end

I was also facing the same issue until I added the type="module" to the script.

Before it was like this

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

And after changing it to

<script type="module" src="../src/main.js"></script>

It worked perfectly.

Nope.

Can use:

IS_COOL NUMBER(1,0)

1 - true
0 - false

Here is the implementation of LinkedList<T>#toArray(T[]):

public <T> T[] toArray(T[] a) {
    if (a.length < size)
        a = (T[])java.lang.reflect.Array.newInstance(
                            a.getClass().getComponentType(), size);
    int i = 0;
    Object[] result = a;
    for (Node<E> x = first; x != null; x = x.next)
        result[i++] = x.item;

    if (a.length > size)
        a[size] = null;

    return a;
}

In short, you could only create generic arrays through Array.newInstance(Class, int) where int is the size of the array.

I used a simple genetic algorithm to optimize the signal to noise ratio of a wave that was represented as a binary string. By flipping the the bits certain ways over several million generations I was able to produce a transform that resulted in a higher signal to noise ratio of that wave. The algorithm could have also been "Simulated Annealing" but was not used in this case. At their core, genetic algorithms are simple, and this was about as simple of a use case that I have seen, so I didn't use a framework for generation creation and selection - only a random seed and the Signal-to-Noise Ratio function at hand.

Roland's answer needs updating. See: https://github.com/hadley/ggplot2/wiki/Share-a-legend-between-two-ggplot2-graphs

This method has been updated for ggplot2 v1.0.0.

library(ggplot2)
library(gridExtra)
library(grid)


grid_arrange_shared_legend <- function(...) {
    plots <- list(...)
    g <- ggplotGrob(plots[[1]] + theme(legend.position="bottom"))$grobs
    legend <- g[[which(sapply(g, function(x) x$name) == "guide-box")]]
    lheight <- sum(legend$height)
    grid.arrange(
        do.call(arrangeGrob, lapply(plots, function(x)
            x + theme(legend.position="none"))),
        legend,
        ncol = 1,
        heights = unit.c(unit(1, "npc") - lheight, lheight))
}

dsamp <- diamonds[sample(nrow(diamonds), 1000), ]
p1 <- qplot(carat, price, data=dsamp, colour=clarity)
p2 <- qplot(cut, price, data=dsamp, colour=clarity)
p3 <- qplot(color, price, data=dsamp, colour=clarity)
p4 <- qplot(depth, price, data=dsamp, colour=clarity)
grid_arrange_shared_legend(p1, p2, p3, p4)

Note the lack of ggplot_gtable and ggplot_build. ggplotGrob is used instead. This example is a bit more convoluted than the above solution but it still solved it for me.

There's a lot of misunderstanding being displayed here. Unicode isn't an encoding, but the Unicode standard is devoted primarily to encoding anyway.

ISO 10646 is the international character set you (probably) care about. It defines a mapping between a set of named characters (e.g., "Latin Capital Letter A" or "Greek small letter alpha") and a set of code points (a number assigned to each -- for example, 61 hexadecimal and 3B1 hexadecimal for those two respectively; for Unicode code points, the standard notation would be U+0061 and U+03B1).

At one time, Unicode defined its own character set, more or less as a competitor to ISO 10646. That was a 16-bit character set, but it was not UTF-16; it was known as UCS-2. It included a rather controversial technique to try to keep the number of necessary characters to a minimum (Han Unification -- basically treating Chinese, Japanese and Korean characters that were quite a bit alike as being the same character).

Since then, the Unicode consortium has tacitly admitted that that wasn't going to work, and now concentrate primarily on ways to encode the ISO 10646 character set. The primary methods are UTF-8, UTF-16 and UCS-4 (aka UTF-32). Those (except for UTF-8) also have LE (little endian) and BE (big-endian) variants.

By itself, "Unicode" could refer to almost any of the above (though we can probably eliminate the others that it shows explicitly, such as UTF-8). Unqualified use of "Unicode" probably happens the most often on Windows, where it will almost certainly refer to UTF-16. Early versions of Windows NT adopted Unicode when UCS-2 was current. After UCS-2 was declared obsolete (around Win2k, if memory serves), they switched to UTF-16, which is the most similar to UCS-2 (in fact, it's identical for characters in the "basic multilingual plane", which covers a lot, including all the characters for most Western European languages).

You can also use stack()

df= DataFrame([list(range(5))], columns = [“a{}”.format(I) for I in range(5)])

After u run df, then run:

df.stack()

You obtain your dataframe in series

DECLARE @NewLineChar AS CHAR(2) = CHAR(13) + CHAR(10)
PRINT ('SELECT FirstLine AS FL ' + @NewLineChar + 'SELECT SecondLine AS SL')

Easiest way to do is :

awk 'NR==FNR{a[$1]++;next} a[$1] ' file1 file2

Files are not necessary to be sorted.

You can use FLUSHALL which will delete all keys from your every database. Where as FLUSHDB will delete all keys from our current database.

Found it with:

sudo tail /var/log/redis/redis-server.log -n 100

So if the setup was more standard that should be:

sudo tail /var/log/redis_6379.log -n 100

This outputs the last 100 lines of the file.

Where your log file is located is in your configs that you can access with:

redis-cli CONFIG GET *

The log file may not always be shown using the above. In that case use

tail -f `less  /etc/redis/redis.conf | grep logfile|cut -d\  -f2`

According to @Data description you can use:

All generated getters and setters will be public. To override the access level, annotate the field or class with an explicit @Setter and/or @Getter annotation. You can also use this annotation (by combining it with AccessLevel.NONE) to suppress generating a getter and/or setter altogether.

Try using:

if(NewType* v = dynamic_cast<NewType*>(old)) {
   // old was safely casted to NewType
   v->doSomething();
}

This requires your compiler to have rtti support enabled.

EDIT: I've had some good comments on this answer!

Every time you need to use a dynamic_cast (or instanceof) you'd better ask yourself whether it's a necessary thing. It's generally a sign of poor design.

Typical workarounds is putting the special behaviour for the class you are checking for into a virtual function on the base class or perhaps introducing something like a visitor where you can introduce specific behaviour for subclasses without changing the interface (except for adding the visitor acceptance interface of course).

As pointed out dynamic_cast doesn't come for free. A simple and consistently performing hack that handles most (but not all cases) is basically adding an enum representing all the possible types your class can have and check whether you got the right one.

if(old->getType() == BOX) {
   Box* box = static_cast<Box*>(old);
   // Do something box specific
}

This is not good oo design, but it can be a workaround and its cost is more or less only a virtual function call. It also works regardless of RTTI is enabled or not.

Note that this approach doesn't support multiple levels of inheritance so if you're not careful you might end with code looking like this:

// Here we have a SpecialBox class that inherits Box, since it has its own type
// we must check for both BOX or SPECIAL_BOX
if(old->getType() == BOX || old->getType() == SPECIAL_BOX) {
   Box* box = static_cast<Box*>(old);
   // Do something box specific
}

Pulling in things from all the answers above, here's what I came up with.

There are essentially two ways to do this:

;WITH TMP AS (
    SELECT CAST(N'' AS XML).value('xs:base64Binary(xs:hexBinary(sql:column("bin")))', 'VARCHAR(MAX)') as  Base64Encoding
    FROM 
    (
        SELECT TOP 10000 CAST(Words AS VARBINARY(MAX)) AS bin FROM TestData
    ) SRC
) 

SELECT *, CAST(CAST(N'' AS XML).value('xs:base64Binary(sql:column("Base64Encoding"))', 'VARBINARY(MAX)') AS NVARCHAR(MAX)) as ASCIIEncoding
FROM
(
    SELECT * FROM TMP
) SRC

And the second way

;WITH TMP AS 
(
    SELECT TOP 10000 CONVERT(VARCHAR(MAX), (SELECT CAST(Wordsas varbinary(max)) FOR XML PATH(''))) as BX
    FROM TestData
)

SELECT *, CONVERT(NVARCHAR(MAX), CONVERT(XML, BX).value('.','varbinary(max)'))
FROM TMP

When comparing performance, the first one has a subtree cost of 2.4414 and the second one has a subtree cost of 4.1538. Which means the first one is about twice as fast as the second one (which is expected, since it uses XML, which is notoriously slow).

Yet another cause of this error is when you are calling the stored procedure from code, and the parameter type in code does not match the type on the stored procedure.

CR - ASCII code 13

LF - ASCII code 10.

Theoretically CR returns cursor to the first position (on the left). LF feeds one line moving cursor one line down. This is how in old days you controled printers and text-mode monitors. These characters are usually used to mark end of lines in text files. Different operating systems used different conventions. As you pointed out Windows uses CR/LF combination while pre-OSX Macs use just CR and so on.

Here is the code

<input type="button" value="Back" onclick="window.history.back()" /> 

Well, without generics, static interfaces are useless because all static method calls are resolved at compile time. So, there's no real use for them.

With generics, they have use -- with or without a default implementation. Obviously there would need to be overriding and so on. However, my guess is that such usage wasn't very OO (as the other answers point out obtusely) and hence wasn't considered worth the effort they'd require to implement usefully.

From a technical point of view they're completely different. <datalist> is an abstract container of options for other elements. In your case you've used it with <input type="text" but you can also use it with ranges, colors, dates etc. http://demo.agektmr.com/datalist/

If using it with text input, as a type of autocomplete, then the question really is: Is it better to use a free-form text input, or a predetermined list of options? In that case I think the answer is a bit more obvious.

If we focus on the use of <datalist> as a list of options for a text field then here are some specific differences between that and a select box:

• A <datalist> fed text box has a single string for both display label and submit. A select box can have a different submit value vs. display label <option value='ie'>Internet Explorer</option>.
• A <datalist> fed text box does not support the <optgroup> tag to organize the display.
• You can not restrict a user to the list of options in a <datalist> like you can with a <select>.
• The onchange event works differently. On a <select> element, the onchange event is fired immediately upon change, whereas with <input type="text" the event is fired after the element loses focus or the user presses enter.
• <datalist> has really spotty support across browsers. The way to show all available options is inconsistent, and things only get worse from there.

The last point is really the big one in my opinion. Since you will HAVE to have a more universal autocomplete fallback, then there is almost no reason to go through the trouble of configuring a <datalist>. Plus any decent autocomplete pluging will allow for ways to style the display of your options, which <datalist> does not do. If <datalist> accepted <li> elements that you could manipulate however you want, it would have been really great! But NO.

Also insofar as i can tell, the <datalist> search is an exact match from the beginning of the string. So if you had <option value="internet explorer"> and you searched for 'explorer' you would get no results. Most autocomplete plugins will search anywhere in the text.

I've only used <datalist> as a quick and lazy convenience helper for some internal pages where I know with a 100% certainty that the users have the latest Chrome or Firefox, and will not try to submit bogus values. For any other case, it's hard to recommend the use of <datalist> due to very poor browser support.

You can use jQuery each function as it is explained below:

Define your data:

var jsonStr = '[{"name":"Lenovo Thinkpad 41A4298,"website":"google"},{"name":"Lenovo Thinkpad 41A2222,"website":"google"},{"name":"Lenovo Thinkpad 41Awww33,"website":"yahoo"},{"name":"Lenovo Thinkpad 41A424448,"website":"google"},{"name":"Lenovo Thinkpad 41A429rr8,"website":"ebay"},{"name":"Lenovo Thinkpad 41A429ff8,"website":"ebay"},{"name":"Lenovo Thinkpad 41A429ss8,"website":"rediff"},{"name":"Lenovo Thinkpad 41A429sg8,"website":"yahoo"}]';

Parse JSON string to JSON object:

var json = JSON.parse(jsonStr);

Iterate and filter:

$.each(JSON.parse(json), function (idx, obj) {
    if (obj.website == 'yahoo') {
        // do whatever you want
    }
});

Use time.sleep()

from time import sleep
sleep(0.05)

An awk solution that store the whole array in memory

    awk '$0!~/^$/{    i++;
                  split($0,arr,FS);
                  for (j in arr) {
                      out[i,j]=arr[j];
                      if (maxr<j){ maxr=j}     # max number of output rows.
                  }
            }
    END {
        maxc=i                 # max number of output columns.
        for     (j=1; j<=maxr; j++) {
            for (i=1; i<=maxc; i++) {
                printf( "%s:", out[i,j])
            }
            printf( "%s\n","" )
        }
    }' infile

But we may "walk" the file as many times as output rows are needed:

#!/bin/bash
maxf="$(awk '{if (mf<NF); mf=NF}; END{print mf}' infile)"
rowcount=maxf
for (( i=1; i<=rowcount; i++ )); do
    awk -v i="$i" -F " " '{printf("%s\t ", $i)}' infile
    echo
done

Which (for a low count of output rows is faster than the previous code).

Laravel >= 5.3

The Auth changes in 5.3 make implementation of this a little easier, and slightly different than 5.2 since the Auth Middleware has been moved to the service container.

Modify the new Middleware auth redirector

/app/Http/Middleware/RedirectIfAuthenticated.php

Change the handle function slightly, so it looks like:

public function handle($request, Closure $next, $guard = null)
{
    if (Auth::guard($guard)->check()) {
        return redirect()->intended('/home');
    }

    return $next($request);
}

TL;DR explanation

The only difference is in the 4th line; by default it looks like this:

return redirect("/home");

Since Laravel >= 5.3 automatically saves the last "intended" route when checking the Auth Guard, it changes to:

return redirect()->intended('/home');

That tells Laravel to redirect to the last intended page before login, otherwise go to "/home" or wherever you'd like to send them by default.

Hope this helps someone else - there's not much out there on the differences between 5.2 and 5.3, and in this area in particular there are quite a few.

in addition to the options shown in your question, there is the possibility of implementing the action directly in your xml file from the menu, for example:

<item
   android:id="@+id/OK_MENU_ITEM"
   android:onClick="showMsgDirectMenuXml" />

And for your Java (Activity) file, you need to implement a public method with a single parameter of type MenuItem, for example:

 private void showMsgDirectMenuXml(MenuItem item) {
    Toast toast = Toast.makeText(this, "OK", Toast.LENGTH_LONG);
    toast.show();
  }

NOTE: This method will have behavior similar to the onOptionsItemSelected (MenuItem item)

If you are using custom TableViewCells, the generic

[self.tableView reloadData];    

does not effectively answer this question unless you leave the current view and come back. Neither does the first answer.

To successfully reload your first table view cell without switching views, use the following code:

//For iOS 5 and later
- (void)reloadTopCell {
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
    NSArray *indexPaths = [[NSArray alloc] initWithObjects:indexPath, nil];
    [self.tableView reloadRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationNone];
}

Insert the following refresh method which calls to the above method so you can custom reload only the top cell (or the entire table view if you wish):

- (void)refresh:(UIRefreshControl *)refreshControl {
    //call to the method which will perform the function
    [self reloadTopCell];

    //finish refreshing 
    [refreshControl endRefreshing];
}

Now that you have that sorted, inside of your viewDidLoad add the following:

//refresh table view
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];

[refreshControl addTarget:self action:@selector(refresh:) forControlEvents:UIControlEventValueChanged];

[self.tableView addSubview:refreshControl];

You now have a custom refresh table feature that will reload the top cell. To reload the entire table, add the

[self.tableView reloadData]; to your new refresh method.

If you wish to reload the data every time you switch views, implement the method:

//ensure that it reloads the table view data when switching to this view
- (void) viewWillAppear:(BOOL)animated {
    [self.tableView reloadData];
}

I would put an absolutely positioned, z-index: 100; span (or spans) with the background: url("myImageWithRoundedCorners.jpg"); set on it inside the #mainWrapperDivWithBGImage .

I´ve solved with this millenary technique (you can leave the Thread.Sleep on his own in the catch)

bool deleted = false;
        do
        {
            try
            {
                Directory.Delete(rutaFinal, true);                    
                deleted = true;
            }
            catch (Exception e)
            {
                string mensaje = e.Message;
                if( mensaje == "The directory is not empty.")
                Thread.Sleep(50);
            }
        } while (deleted == false);

This is a improve code from @MiFi. This one order in abs but not excluding the negative values.

   def top_correlation (df,n):
    corr_matrix = df.corr()
    correlation = (corr_matrix.where(np.triu(np.ones(corr_matrix.shape), k=1).astype(np.bool))
                 .stack()
                 .sort_values(ascending=False))
    correlation = pd.DataFrame(correlation).reset_index()
    correlation.columns=["Variable_1","Variable_2","Correlacion"]
    correlation = correlation.reindex(correlation.Correlacion.abs().sort_values(ascending=False).index).reset_index().drop(["index"],axis=1)
    return correlation.head(n)

top_correlation(ANYDATA,10)

If you know the some content of the file you can try to decode it with several encoding and see which is missing. In general there is no way since a text file is a text file and those are stupid ;)

You have two ways:

First go to the particular path of Android SDK:

1) Open your command prompt and traverse to the platform-tools directory through it such as

$ cd Frameworks\Android-Sdk\platform-tools

2) Run your adb commands now such as to know that your adb is working properly :

$ adb devices OR adb logcat OR simply adb

Second way is :

1) Right click on your My Computer.

2) Open Environment variables.

3) Add new variable to your System PATH variable(Add if not exist otherwise no need to add new variable if already exist).

4) Add path of platform-tools directory to as value of this variable such as C:\Program Files\android-sdk\platform-tools.

5) Restart your computer once.

6) Now run the above adb commands such adb devices or other adb commands from anywhere in command prompt.

Also on you can fire a command on terminal setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools"

A recursive cte based solution

Don't use Logula

I've actually followed the recommendation of Eugene and tried it and found out that it has a clumsy configuration and is subjected to bugs, which don't get fixed (such as this one). It doesn't look to be well maintained and it doesn't support Scala 2.10.

Use slf4s + slf4j-simple

Key benefits:

• Supports latest Scala 2.10 (to date it's M7)
• Configuration is versatile but couldn't be simpler. It's done with system properties, which you can set either by appending something like -Dorg.slf4j.simplelogger.defaultlog=trace to execution command or hardcode in your script: System.setProperty("org.slf4j.simplelogger.defaultlog", "trace"). No need to manage trashy config files!
• Fits nicely with IDEs. For instance to set the logging level to "trace" in a specific run configuration in IDEA just go to Run/Debug Configurations and add -Dorg.slf4j.simplelogger.defaultlog=trace to VM options.
• Easy setup: just drop in the dependencies from the bottom of this answer

Here's what you need to be running it with Maven:

<dependency>
  <groupId>com.weiglewilczek.slf4s</groupId>
  <artifactId>slf4s_2.9.1</artifactId>
  <version>1.0.7</version>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-simple</artifactId>
  <version>1.6.6</version>
</dependency>

Perhaps an example will help:

git rm --cached asd
git commit -m "the file asd is gone from the repository"

versus

git reset HEAD -- asd
git commit -m "the file asd remains in the repository"

Note that if you haven't changed anything else, the second commit won't actually do anything.

Static libraries do not link with other static libraries. The only way to do this is to use your librarian/archiver tool (for example ar on Linux) to create a single new static library by concatenating the multiple libraries.

Edit: In response to your update, the only way I know to select only the symbols that are required is to manually create the library from the subset of the .o files that contain them. This is difficult, time consuming and error prone. I'm not aware of any tools to help do this (not to say they don't exist), but it would make quite an interesting project to produce one.

Xcode 10.2.1 was not recognizing my ipad mini. I unplugged and rebooted the mini and it became visible.

As per your code your "number" and "Name" are primarykey and you are inserting S.NAME in both row so it will make a conflict. we are using primarykey for accessing complete data. here you cant access the data using the primarykey 'name'.

im a beginner and i think it might be the error.

Use set_index with stack for MultiIndex Series, then for DataFrame add reset_index with rename:

df1 = (df.set_index(["location", "name"])
         .stack()
         .reset_index(name='Value')
         .rename(columns={'level_2':'Date'}))
print (df1)
  location  name        Date  Value
0        A  test    Jan-2010     12
1        A  test    Feb-2010     20
2        A  test  March-2010     30
3        B   foo    Jan-2010     18
4        B   foo    Feb-2010     20
5        B   foo  March-2010     25

To get exact character count of string, use printf, as opposed to echo, cat, or running wc -c directly on a file, because using echo, cat, etc will count a newline character, which will give you the amount of characters including the newline character. So a file with the text 'hello' will print 6 if you use echo etc, but if you use printf it will return the exact 5, because theres no newline element to count.

How to use printf for counting characters within strings:

$printf '6chars' | wc -m
6

To turn this into a script you can run on a text file to count characters, save the following in a file called print-character-amount.sh:

#!/bin/bash
characters=$(cat "$1")
printf "$characters" | wc -m

chmod +x on file print-character-amount.sh containing above text, place the file in your PATH (i.e. /usr/bin/ or any directory exported as PATH in your .bashrc file) then to run script on text file type:

print-character-amount.sh file-to-count-characters-of.txt

This is the fastest solution that does not require you to know or calculate the overall buffer size first:

var data []byte
for i := 0; i < 1000; i++ {
    data = append(data, getShortStringFromSomewhere()...)
}
return string(data)

By my benchmark, it's 20% slower than the copy solution (8.1ns per append rather than 6.72ns) but still 55% faster than using bytes.Buffer.

Use a regular expression on a string:

def is_numeric?(obj) 
   obj.to_s.match(/\A[+-]?\d+?(\.\d+)?\Z/) == nil ? false : true
end

If you want to check if a variable is of certain type, you can simply use kind_of?:

1.kind_of? Integer #true
(1.5).kind_of? Float #true
is_numeric? "545"  #true
is_numeric? "2aa"  #false

Use zip(*list):

>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]

The zip() function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l you apply all tuples in l as separate arguments to the zip() function, so zip() pairs up 1 with 3 with 8 first, then 2 with 4 and 9. Those happen to correspond nicely with the columns, or the transposition of l.

zip() produces tuples; if you must have mutable list objects, just map() the tuples to lists or use a list comprehension to produce a list of lists:

map(list, zip(*l))          # keep it a generator
[list(t) for t in zip(*l)]  # consume the zip generator into a list of lists

You can only use Core Graphics (Quartz, 2D only) transforms directly applied to a UIView's transform property. To get the effects in coverflow, you'll have to use CATransform3D, which are applied in 3-D space, and so can give you the perspective view you want. You can only apply CATransform3Ds to layers, not views, so you're going to have to switch to layers for this.

Check out the "CovertFlow" sample that comes with Xcode. It's mac-only (ie not for iPhone), but a lot of the concepts transfer well.

try like below it will work...

<html>
<head>
<script>
function displayResult(element)
{
document.getElementById(element).value = 'hi';
}
</script>
</head>
<body>

<textarea id="myTextarea" cols="20">
BYE
</textarea>
<br>

<button type="button" onclick="displayResult('myTextarea')">Change</button>

</body>
</html>

Maybe you can try this one:

if (isset($_POST['mail']) && ($_POST['mail'] !=0)) { echo "Yes, mail is set"; } else { echo "No, mail is not set"; }

Wasted a few hours trying some of these solutions but eventually traced this to a corporate IPS (Instrusion Protection System) dropping the connection after a certain amount of data is transferred.

$('div','#container')

to this

$('#div1, #div2, #div3')

text = "just trying out"

word_list = []

for i in range(0, len(text)):
    word_list.append(text[i])
    i+=1

.container_box{
    text-align:center
}

use span istead of the inner divs

<div class="container_box">

The App-Secret key should be kept private - but when releasing the app they can be reversed by some guys.

for those guys it will not hide, lock the either the ProGuard the code. It is a refactor and some payed obfuscators are inserting a few bitwise operators to get back the jk433g34hg3 String. You can make 5 -15 min longer the hacking if you work 3 days :)

Best way is to keep it as it is, imho.

Even if you store at server side( your PC ) the key can be hacked and printed out. Maybe this takes the longest? Anyhow it is a matter of few minutes or a few hours in best case.

A normal user will not decompile your code.

That should work. Better if you pass a function to val:

$('#replyBox').val(function(i, text) {
    return text + quote;
});

This way you avoid searching the element and calling val twice.

git update-index should do what you want

This will tell git you want to start ignoring the changes to the file
git update-index --assume-unchanged path/to/file

When you want to start keeping track again
git update-index --no-assume-unchanged path/to/file

Github Documentation: update-index

For doing FORM posts, the best way is to use WebClient.UploadValues() with a POST method.

It is very simple.

If you don't care about checking the validity of the certificate just add the --no-check-certificate option on the wget command-line. This worked well for me.

NOTE: This opens you up to man-in-the-middle (MitM) attacks, and is not recommended for anything where you care about security.

Hope this will help you

Cast(columnName as Numeric(10,2)) 
        or

Cast(@s as decimal(10,2))

I am not getting why you want to cast to varchar?.If you cast to varchar again convert back to decimail for two decimal points

Left shift <<

This is somehow easy and whenever you use the shift operator, it is always a bit-wise operation, so we can't use it with a double and float operation. Whenever we left shift one zero, it is always added to the least significant bit (LSB).

But in right shift >> we have to follow one additional rule and that rule is called "sign bit copy". Meaning of "sign bit copy" is if the most significant bit (MSB) is set then after a right shift again the MSB will be set if it was reset then it is again reset, means if the previous value was zero then after shifting again, the bit is zero if the previous bit was one then after the shift it is again one. This rule is not applicable for a left shift.

The most important example on right shift if you shift any negative number to right shift, then after some shifting the value finally reach to zero and then after this if shift this -1 any number of times the value will remain same. Please check.

public static TreeMap<String, String> sortMap(HashMap<String, String> passedMap, String byParam) {
    if(byParam.trim().toLowerCase().equalsIgnoreCase("byValue")) {
        // Altering the (key, value) -> (value, key)
        HashMap<String, String> newMap =  new HashMap<String, String>();
        for (Map.Entry<String, String> entry : passedMap.entrySet()) {
            newMap.put(entry.getValue(), entry.getKey());
        }
        return new TreeMap<String, String>(newMap);
    }
    return new TreeMap<String, String>(passedMap);
}

It sounds like you're not instantiating your class. That's the primary reason I get the "an object reference is required" error.

MyClass myClass = new MyClass();

once you've added that line you can then call your method

myClass.myMethod();

Also, are all of your classes in the same namespace? When I was first learning c# this was a common tripping point for me.

You can find all database names with this:-

 select name from sys.sysdatabases

Unfortunately for MSForms list box looping through the list items and checking their Selected property is the only way. However, here is an alternative. I am storing/removing the selected item in a variable, you can do this in some remote cell and keep track of it :)

Dim StrSelection As String

Private Sub ListBox1_Change()
    If ListBox1.Selected(ListBox1.ListIndex) Then
        If StrSelection = "" Then
            StrSelection = ListBox1.List(ListBox1.ListIndex)
        Else
            StrSelection = StrSelection & "," & ListBox1.List(ListBox1.ListIndex)
        End If
    Else
        StrSelection = Replace(StrSelection, "," & ListBox1.List(ListBox1.ListIndex), "")
    End If
End Sub

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

try checking with any Url like add

https://www.google.com

in path and start activity if its works than you are adding wrong path

if exists(select * from db1.table1 where sno=1 )
begin
select * from db1.table1 where sno=1 
end
else if (select * from db2.table1 where sno=1 )
begin
select * from db2.table1 where sno=1 
end
else
begin
print 'the record does not exits'
end

Separating HTML from PHP is the best method. It's less confusing and easy to debug.

<?php
  while($var)
  {
?>

     <div>
         <h3><a href="User<?php echo $i;?>"><?php echo $i;?></a></h3>
         <div>Lorem ipsum dolor sit amet.</div>
     </div>

<?php
  $i++;
  }
?>
