Intro: I assume that you have a matrix X where each row/line is a sample/observation and each column is a variable/feature (this is the expected input for any sklearn ML function by the way -- X.shape should be [number_of_samples, number_of_features]).

Core of method: The main idea is to normalize/standardize i.e. µ = 0 and s = 1 your features/variables/columns of X, individually, before applying any machine learning model.

StandardScaler() will normalize the features i.e. each column of X, INDIVIDUALLY, so that each column/feature/variable will have µ = 0 and s = 1.

P.S: I find the most upvoted answer on this page, wrong. I am quoting "each value in the dataset will have the sample mean value subtracted" -- This is neither true nor correct.

See also: How and why to Standardize your data: A python tutorial

Example:

from sklearn.preprocessing import StandardScaler
import numpy as np

# 4 samples/observations and 2 variables/features
data = np.array([[0, 0], [1, 0], [0, 1], [1, 1]])
scaler = StandardScaler()
scaled_data = scaler.fit_transform(data)

print(data)
[[0, 0],
 [1, 0],
 [0, 1],
 [1, 1]])

print(scaled_data)
[[-1. -1.]
 [ 1. -1.]
 [-1.  1.]
 [ 1.  1.]]

Verify that the mean of each feature (column) is 0:

scaled_data.mean(axis = 0)
array([0., 0.])

Verify that the std of each feature (column) is 1:

scaled_data.std(axis = 0)
array([1., 1.])

The maths:

UPDATE 08/2020: Concerning the input parameters with_mean and with_std to False/True, I have provided an answer here: StandardScaler difference between “with_std=False or True” and “with_mean=False or True”

The "Python Packaging Authority" has a sampleproject:

https://github.com/pypa/sampleproject

It is a sample project that exists as an aid to the Python Packaging User Guide's Tutorial on Packaging and Distributing Projects.

Make the background image transparent/semi-transparent. If it's a solid coloured background just create a 1px by 1px image in fireworks or whatever and adjust its opacity...

I know this is an old question, with quite a few answers, but I was surprised to find that no one was suggesting the naming convention used in the official documentation:

$ docker build -f dockerfiles/Dockerfile.debug -t myapp_debug .
$ docker build -f dockerfiles/Dockerfile.prod  -t myapp_prod .

The above commands will build the current build context (as specified by the .) twice, once using a debug version of a Dockerfile and once using a production version.

In summary, if you have a file called Dockerfile in the root of your build context it will be automatically picked up. If you need more than one Dockerfile for the same build context, the suggested naming convention is:

Dockerfile.<purpose>

These dockerfiles could be in the root of your build context or in a subdirectory to keep your root directory more tidy.

From your comment:

Example: WHERE (Note is null) ^ (ID is null)

you could probably try:

where
   (case when Note is null then 1 else 0 end)
 <>(case when ID is null then 1 else 0 end)

I used your own pivot as a nested query and came to this result:

SELECT
  [sub].[chardate],
  SUM(ISNULL([Australia], 0)) AS [Transactions Australia],
  SUM(CASE WHEN [Australia] IS NOT NULL THEN [TotalAmount] ELSE 0 END) AS [Amount Australia],
  SUM(ISNULL([Austria], 0)) AS [Transactions Austria],
  SUM(CASE WHEN [Austria] IS NOT NULL THEN [TotalAmount] ELSE 0 END) AS [Amount Austria]
FROM
(
  select * 
  from  mytransactions
  pivot (sum (totalcount) for country in ([Australia], [Austria])) as pvt
) AS [sub]
GROUP BY
  [sub].[chardate],
  [sub].[numericmonth]
ORDER BY 
  [sub].[numericmonth] ASC

Here is the Fiddle.

According to git push documentation:

git push origin HEAD
    A handy way to push the current branch to the same name on the remote.

So I think what you need is git push origin HEAD. Also it can be useful git push -u origin HEAD to set upstream tracking information in the local branch, if you haven't already pushed to the origin.

You just need to enter this command:

sudo apt-get install gcc

If you're using some plugin which takes string and use construct Regex to create Regex Object i:e new RegExp()

Than Below string will work

'^\\S*$'

It's same regex @Bergi mentioned just the string version for new RegExp constructor

It is crucial to know that attributes are not parameters.

The return type for attributes is an Object, whereas the return type for a parameter is a String. When calling the getAttribute(String name) method, bear in mind that the attributes must be cast.

Additionally, there is no servlet specific attributes, and there are no session parameters.

This post is written with the purpose to connect on @Bozho's response, as additional information that can be useful for other people.

ThulasiRam, I prefer your suggestion. It works well for me in a slightly different syntax/context:

var dt_to = $.datepicker.formatDate('yy-mm-dd', new Date());

If you decide to utilize datepicker from JQuery UI, make sure you use proper references in your document's < head > section:

<link rel="stylesheet" href="http://code.jquery.com/ui/1.9.2/themes/base/jquery-ui.css" />

<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script> 

This may help. Peter's Login Redirect

Redirect users to different locations after logging in and logging out.

Define a set of redirect rules for specific users, users with specific roles, users with specific capabilities, and a blanket rule for all other users. Also, set a redirect URL for post-registration. This is all managed in Settings > Login/logout redirects.

You can use the syntax [variable]username[/variable] in your URLs so that the system will build a dynamic URL upon each login, replacing that text with the user's username. In addition to username, there is "userslug", "homeurl", "siteurl", "postid-23", "http_referer" and you can also add your own custom URL "variables"...

 String s1="[a,b,c,d]";
 String replace = s1.replace("[","");
 System.out.println(replace);
 String replace1 = replace.replace("]","");
 System.out.println(replace1);
 List<String> myList = new ArrayList<String>(Arrays.asList(replace1.split(",")));
 System.out.println(myList.toString());

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

Or.... Call your main .bat file from another .bat file and output the result to a result file i.e.

runner.bat > mainresults.txt

Where runner.bat calls the main .bat file

You should see all the actions performed in the main .bat file now

$('input, select').attr('disabled', 'disabled');

If you want to do this without a bunch of server-side processing within the page, it might be a feasible idea to blow the text value into a hidden field (using PHP). Then you can use jQuery to process the hidden field value.

Whatever floats your boat :)

You could use underscore.js and the each function:

_.each({key1: "value1", key2: "value2"}, function(value) {
  console.log(value);
});

One workaround I had for this was to iterate over the sectors(which at the time you could do...I haven't tested that recently).

You wind up getting blocked eventually when you do it that way though, since YQL gets throttled per day.

Use the CSV API whenever possible to avoid this.

You can use some function to initialize struct as follows,

typedef struct
{
    int flag;
} MyStruct;

MyStruct GetMyStruct(int value)
{
    MyStruct My = {0};
    My.flag = value;
    return My;
}

void main (void)
{
    MyStruct temp;
    temp = GetMyStruct(3);
    printf("%d\n", temp.flag);
}

EDIT:

typedef struct
{
    int flag;
} MyStruct;

MyStruct MyData[20];

MyStruct GetMyStruct(int value)
{
    MyStruct My = {0};
    My.flag = value;
    return My;
}

void main (void)
{
    int i;
    for (i = 0; i < 20; i ++)
        MyData[i] = GetMyStruct(3);

    for (i = 0; i < 20; i ++)
        printf("%d\n", MyData[i].flag);
}

Use:

docker inspect -f "{{.Path}} {{.Args}} ({{.Id}})" $(docker ps -a -q)

That will display the command path and arguments, similar to docker ps.

Define a new URL object, assign it the current url, append your parameter(s) to that URL object and finally push it to your browsers state.

var url = new URL(window.location.href);
//var url = new URL(window.location.origin + window.location.pathname) <- flush existing parameters
url.searchParams.append("order", orderId);
window.history.pushState(null, null, url);

For the former, convention over configuration. Rails default when you reference another table with

 belongs_to :something

is to look for something_id.

references, or belongs_to is actually newer way of writing the former with few quirks.

Important is to remember that it will not create foreign keys for you. In order to do that, you need to set it up explicitly using either:

t.references :something, foreign_key: true
t.belongs_to :something_else, foreign_key: true

or (note the plural):

add_foreign_key :table_name, :somethings
add_foreign_key :table_name, :something_elses`

Writing your own parser is fun, but likely you should have a look at Open CSV. It provides numerous ways of accessing the CSV and also allows to generate CSV. And it does handle escapes properly. As mentioned in another post, there is also a CSV-parsing lib in the Apache Commons, but that one isn't released yet.

w3school offered this way:

echo nl2br("One line.\n Another line.");

by use of this function you can do it..i tried other ways that said above but they wont help me..

Try using isnull(a), isnotnull(a), nvl(), etc. On some versions(potentially in conjunction with the server settings - atleast with the one I am working on) of hive the 'IS NULL' and 'IS NOT NULL' syntax does not execute the logic when it is compiled. Check here for more information.

Some more convenient

"1,1200.00".gsub(/[^0-9]/,'') 

it makes "1 200 200" work properly aswell

I've found that you can move div elements to the next line simply by setting the property Display: block;

On each div.

Andy's solution does not work for me. Here I found another way:

git checkout `git rev-list -n 1 --before="2009-07-27 13:37" master`

Git: checkout by date

From the sending Activity try the following code

   //EXTRA_MESSAGE is our key and it's value is 'packagename.MESSAGE'
    public static final String EXTRA_MESSAGE = "packageName.MESSAGE";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
       ....

        //Here we declare our send button
        Button sendButton = (Button) findViewById(R.id.send_button);
        sendButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //declare our intent object which takes two parameters, the context and the new activity name

                // the name of the receiving activity is declared in the Intent Constructor
                Intent intent = new Intent(getApplicationContext(), NameOfReceivingActivity.class);

                String sendMessage = "hello world"
                //put the text inside the intent and send it to another Activity
                intent.putExtra(EXTRA_MESSAGE, sendMessage);
                //start the activity
                startActivity(intent);

            }

From the receiving Activity try the following code:

   protected void onCreate(Bundle savedInstanceState) {
 //use the getIntent()method to receive the data from another activity
 Intent intent = getIntent();

//extract the string, with the getStringExtra method
String message = intent.getStringExtra(NewActivityName.EXTRA_MESSAGE);

Then just add the following code to the AndroidManifest.xml file

  android:name="packagename.NameOfTheReceivingActivity"
  android:label="Title of the Activity"
  android:parentActivityName="packagename.NameOfSendingActivity"

During my current projects, I'm often passing rear parts of a path to a function and therefore use the Path module. To get the n-th part in reverse order, I'm using:

from typing import Union
from pathlib import Path

def get_single_subpath_part(base_dir: Union[Path, str], n:int) -> str:
    if n ==0:
        return Path(base_dir).name
    for _ in range(n):
        base_dir = Path(base_dir).parent
    return getattr(base_dir, "name")

path= "/folderA/folderB/folderC/folderD/"

# for getting the last part:
print(get_single_subpath_part(path, 0))
# yields "folderD"

# for the second last
print(get_single_subpath_part(path, 1))
#yields "folderC"

Furthermore, to pass the n-th part in reverse order of a path containing the remaining path, I use:

from typing import Union
from pathlib import Path

def get_n_last_subparts_path(base_dir: Union[Path, str], n:int) -> Path:
    return Path(*Path(base_dir).parts[-n-1:])

path= "/folderA/folderB/folderC/folderD/"

# for getting the last part:
print(get_n_last_subparts_path(path, 0))
# yields a `Path` object of "folderD"

# for second last and last part together 
print(get_n_last_subparts_path(path, 1))
# yields a `Path` object of "folderc/folderD"

Note that this function returns a Pathobject which can easily be converted to a string (e.g. str(path))

Coming from the embedded world, I would like to add that the concept of processes only exists in "big" processors (desktop CPUs, ARM Cortex A-9) that have MMU (memory management unit) , and operating systems that support using MMUs (such as Linux). With small/old processors and microcontrollers and small RTOS operating system (real time operating system), such as freeRTOS, there is no MMU support and thus no processes but only threads.

Threads can access each others memory, and they are scheduled by OS in an interleaved manner so they appear to run in parallel (or with multi-core they really run in parallel).

Processes, on the other hand, live in their private sandbox of virtual memory, provided and guarded by MMU. This is handy because it enables:

1. keeping buggy process from crashing the entire system.
2. Maintaining security by making other processes data invisible and unreachable. The actual work inside the process is taken care by one or more threads.

In one reusable piece of code I use the directive <%@include file="reuse.html"%> and in the second I use the standard action <jsp:include page="reuse.html" />.

Let the code in the reusable file be:

<html>
<head>
    <title>reusable</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
    <img src="candle.gif" height="100" width="50"/> <br />
    <p><b>As the candle burns,so do I</b></p>
</body>

After running both the JSP files you see the same output and think if there was any difference between the directive and the action tag. But if you look at the generated servlet of the two JSP files, you will see the difference.

Here is what you will see when you use the directive:

out.write("<html>\r\n");
out.write("    <head>\r\n");
out.write("        <title>reusable</title>\r\n");
out.write("        <meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">\r\n");
out.write("    </head>\r\n");
out.write("    <body>\r\n");
out.write("        <img src=\"candle.gif\" height=\"100\" width=\"50\"/> <br />\r\n");
out.write("        <p><b>As the candle burns,so do I</b></p>\r\n");
out.write("    </body>\r\n");
out.write("</html>\r\n");
 

And this is what you will see for the used standard action in the second JSP file :

org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, "reusable.html", out, false);

So now you know that the include directive inserts the source of reuse.html at translation time, but the action tag inserts the response of reuse.html at runtime.

If you think about it, there is an extra performance hit with every action tag (<jsp:include>). It means you can guarantee you will always have the latest content, but it increases performance cost.

There exists an on-line tool called IETransformsTranslator. With this tool you can make matrix filter transforms what works on IE6,IE7 & IE8. Just paste you CSS3 transform functions (e.g. rotate(15deg) ) and it will do the rest. http://www.useragentman.com/IETransformsTranslator/

public boolean isInternetWorking() {
    boolean success = false;
    try {
        URL url = new URL("https://google.com");
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setConnectTimeout(10000);
        connection.connect();
        success = connection.getResponseCode() == 200;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return success;
}

return true if internet is actually available

Make sure you have these two permission

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

if http does not work its because of the new android security they donot allow plain text communication now. for now just to by pass it.

android:usesCleartextTraffic="true"

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

If you're just checking if word is a number, that's not too hard:

#include <ctype.h>

...

string word;
bool isNumber = true;
for(string::const_iterator k = word.begin(); k != word.end(); ++k)
    isNumber &&= isdigit(*k);

Optimize as desired.

The way is

$ > g++ -lpthread perform.c -o per
$ > time ./per

output is >>

real    0m0.014s
user    0m0.010s
sys     0m0.002s

Use the ListView.ItemContainerStyle property to give your ListViewItems an EventSetter that will handle the PreviewMouseLeftButtonDown event. Then, in the handler, check to see if the item that was clicked is selected.

XAML:

<ListView ItemsSource={Binding MyItems}>
    <ListView.View>
        <GridView>
            <!-- declare a GridViewColumn for each property -->
        </GridView>
    </ListView.View>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

Code-behind:

private void ListViewItem_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    var item = sender as ListViewItem;
    if (item != null && item.IsSelected)
    {
        //Do your stuff
    }
}

According to new Gradle based build system. We have to put assets under main folder.

Or simply right click on your project and create it like

File > New > folder > assets Folder

Since you are using jQuery, you might as well use the each method... Also, it seems like everything is a value of the property 'd' in this JS Object [Notation].

$.each(result.d,function(i) {
    // In case there are several values in the array 'd'
    $.each(this,function(j) {
        // Apparently doesn't work...
        alert(this.EmployeeName);
        // What about this?
        alert(result.d[i][j]['EmployeeName']);
        // Or this?
        alert(result.d[i][j].EmployeeName);
    });
});

That should work. if not, then maybe you can give us a longer example of the JSON.

Edit: If none of this stuff works then I'm starting to think there might be something wrong with the syntax of your JSON.

There is no built-in function in Javascript to perform this search.

If you are using jQuery you could do a jQuery.inArray(element,array).

Try this simple code it will do the job.

DecimalFormat format = new DecimalFormat( "#.0" );
TextField field = new TextField();
field.setTextFormatter( new TextFormatter<>(c ->
{
    if ( c.getControlNewText().isEmpty() )
    {
        return c;
    }

    ParsePosition parsePosition = new ParsePosition( 0 );
    Object object = format.parse( c.getControlNewText(), parsePosition );

    if ( object == null || parsePosition.getIndex() <          c.getControlNewText().length() )
    {
        return null;
    }
    else
    {
        return c;
    }
}));

I think I found a simpler solution, only this uses a subclass of ViewPager instead of (its parent) ScrollView.

UPDATE 2013-07-16: I added an override for onTouchEvent as well. It could possibly help with the issues mentioned in the comments, although YMMV.

public class UninterceptableViewPager extends ViewPager {

    public UninterceptableViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        boolean ret = super.onInterceptTouchEvent(ev);
        if (ret)
            getParent().requestDisallowInterceptTouchEvent(true);
        return ret;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        boolean ret = super.onTouchEvent(ev);
        if (ret)
            getParent().requestDisallowInterceptTouchEvent(true);
        return ret;
    }
}

This is similar to the technique used in android.widget.Gallery's onScroll(). It is further explained by the Google I/O 2013 presentation Writing Custom Views for Android.

Update 2013-12-10: A similar approach is also described in a post from Kirill Grouchnikov about the (then) Android Market app.

You should use method array_push to add value or array to array exists

$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);

/** GENERATED OUTPUT
Array
(
    [0] => orange
    [1] => banana
    [2] => apple
    [3] => raspberry
)
*/

var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:

var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);

There are many ways to do what you want; however, do note that it is quite possible that —as described in the question— you don't have to call the function inside the loop.

If you insist in having the function call inside the loop, you can also do:

needs_to_run= expensive_function
while 1:
    …
    if needs_to_run: needs_to_run(); needs_to_run= None
    …

You can check if it can be converted to decimal. If yes, then its a number

from decimal import Decimal

def is_number(value):
    try:
        value = Decimal(value)
        return True
    except:
        return False

print is_number(None)   // False
print is_number(0)      // True
print is_number(2.3)    // True
print is_number('2.3')  // True (caveat!)

The simplest way to install setuptools when it isn't already there and you can't use a package manager is to download ez_setup.py and run it with the appropriate Python interpreter. This works even if you have multiple versions of Python around: just run ez_setup.py once with each Python.

Edit: note that recent versions of Python 3 include setuptools in the distribution so you no longer need to install separately. The script mentioned here is only relevant for old versions of Python.

zvolkov's answer is the perfect one to find out if there is such a customer. If you need to use the customer afterwards, you can do:

Customer customer = list.FirstOrDefault(cus => cus.FirstName == "John");
if (customer != null)
{
    // Use customer
}

I know this isn't what you were asking, but I thought I'd pre-empt a follow-on question :) (Of course, this only finds the first such customer... to find all of them, just use a normal where clause.)

I was looking for the same behavior using jdbi's BindBeanList and found the syntax is exactly the same as Peter Lang's answer above. In case anybody is running into this question, here's my code:

  @SqlUpdate("INSERT INTO table_one (col_one, col_two) VALUES <beans> ON DUPLICATE KEY UPDATE col_one=VALUES(col_one), col_two=VALUES(col_two)")
void insertBeans(@BindBeanList(value = "beans", propertyNames = {"colOne", "colTwo"}) List<Beans> beans);

One key detail to note is that the propertyName you specify within @BindBeanList annotation is not same as the column name you pass into the VALUES() call on update.

You need to reverse the nesting inside the generate block:

genvar c;
generate
    for (c = 0; c < ROWBITS; c = c + 1) begin: test
        always @(posedge sysclk) begin
            temp[c] <= 1'b0;
        end
    end
endgenerate

Technically, this generates four always blocks:

always @(posedge sysclk) temp[0] <= 1'b0;
always @(posedge sysclk) temp[1] <= 1'b0;
always @(posedge sysclk) temp[2] <= 1'b0;
always @(posedge sysclk) temp[3] <= 1'b0;

In this simple example, there's no difference in behavior between the four always blocks and a single always block containing four assignments, but in other cases there could be.

The genvar-dependent operation needs to be resolved when constructing the in-memory representation of the design (in the case of a simulator) or when mapping to logic gates (in the case of a synthesis tool). The always @posedge doesn't have meaning until the design is operating.

Subject to certain restrictions, you can put a for loop inside the always block, even for synthesizable code. For synthesis, the loop will be unrolled. However, in that case, the for loop needs to work with a reg, integer, or similar. It can't use a genvar, because having the for loop inside the always block describes an operation that occurs at each edge of the clock, not an operation that can be expanded statically during elaboration of the design.

To create a virtual environment for your project, open a new command prompt, navigate to the folder where you want to create your project and then enter the following:

py -m venv project-name This will create a folder called ‘project-name’ if it does not already exist and setup the virtual environment. To activate the environment, run: project-name\Scripts\activate.bat**

The virtual environment will be activated and you’ll see “(project-name)” next to the command prompt to designate that. Each time you start a new command prompt, you’ll need to activate the environment again.

Install Django

Django can be installed easily using pip within your virtual environment.

In the command prompt, ensure your virtual environment is active, and execute the following command:

py -m pip install Django

You can't, because IEnumerable doesn't have an index at all... if you are sure your enumerable has less than int.MaxValue elements (or long.MaxValue if you use a long index), you can:

1. Don't use foreach, and use a for loop, converting your IEnumerable to a generic enumerable first:

   var genericList = list.Cast<object>();
   for(int i = 0; i < genericList.Count(); ++i)
   {
      var row = genericList.ElementAt(i);
      /* .... */
   }
   

2. Have an external index:

   int i = 0;
   foreach(var row in list)
   {
      /* .... */
      ++i;
   }
   

3. Get the index via Linq:

   foreach(var rowObject in list.Cast<object>().Select((r, i) => new {Row=r, Index=i}))
   {
     var row = rowObject.Row;
     var i = rowObject.Index;
     /* .... */    
   }
   

In your case, since your IEnumerable is not a generic one, I'd rather use the foreach with external index (second method)... otherwise, you may want to make the Cast<object> outside your loop to convert it to an IEnumerable<object>.

Your datatype is not clear from the question, but I'm assuming object since it's an items source (it could be DataGridRow)... you may want to check if it's directly convertible to a generic IEnumerable<object> without having to call Cast<object>(), but I'll make no such assumptions.

All this said:

The concept of an "index" is foreign to an IEnumerable. An IEnumerable can be potentially infinite. In your example, you are using the ItemsSource of a DataGrid, so more likely your IEnumerable is just a list of objects (or DataRows), with a finite (and hopefully less than int.MaxValue) number of members, but IEnumerable can represent anything that can be enumerated (and an enumeration can potentially never end).

Take this example:

public static IEnumerable InfiniteEnumerable()
{
  var rnd = new Random();
  while(true)
  {
    yield return rnd.Next();
  }
}

So if you do:

foreach(var row in InfiniteEnumerable())
{
  /* ... */
}

Your foreach will be infinite: if you used an int (or long) index, you'll eventually overflow it (and unless you use an unchecked context, it'll throw an exception if you keep adding to it: even if you used unchecked, the index would be meaningless also... at some point -when it overflows- the index will be the same for two different values).

So, while the examples given work for a typical usage, I'd rather not use an index at all if you can avoid it.

Try this, working fine -

$array = json_decode(json_encode($array), true);

You can add image to asp.net button. you dont need to use only image button or link button. When displaying button on browser, it is converting to html button as default. So you can use its "Style" properties for adding image. My example is below. I hope it works for you.

Style="background-image:url('Image/1.png');"

You can change image location with using

background-repeat

properties. So you can write a button like below:

<asp:Button ID="btnLogin" runat="server" Text="Login" Style="background-image:url('Image/1.png'); background-repeat:no-repeat"/>

This answer may be late reply but it will be useful for seeing this topic in future.

The features of .NET framework 4.5 can be seen in the following link.

To summarize:

• Installation

  .NET Framework 4.5 does not support Windows XP or Windows Server 2003, and therefore, if you have to create applications that target these operating systems, you will need to stay with .NET Framework 4.0. In contrast, Windows 8 and Windows Server 2012 in all of their editions include .NET Framework 4.5.

• Support for Arrays Larger than 2 GB on 64-bit Platforms
• Enhanced Background Server Garbage Collection
• Support for Timeouts in Regular Expression Evaluations
• Support for Unicode 6.0.0 in Culture-Sensitive Sorting and Casing Rules on Windows 8
• Simple Default Culture Definition for an Application Domain
• Internationalized Domain Names in Windows 8 Apps

in python only work

a=4
b=3

i=a+b

which i is new operator

You should also be able to accomplish a similar thing using the premain method of a Java agent.

The manifest of the agent JAR file must contain the attribute Premain-Class. The value of this attribute is the name of the agent class. The agent class must implement a public static premain method similar in principle to the main application entry point. After the Java Virtual Machine (JVM) has initialized, each premain method will be called in the order the agents were specified, then the real application main method will be called. Each premain method must return in order for the startup sequence to proceed.

You need to add:

 #include <cstdlib>

in order for the compiler to see the prototype for system().

You can use the indexOf method like this:

var index = array.indexOf(item);
if (index !== -1) {
  array.splice(index, 1);
}

Note: You'll need to shim it for IE8 and below

var array = [1,2,3,4]
var item = 3

var index = array.indexOf(item);
array.splice(index, 1);

console.log(array)

You can use with jQuery

jQuery(window).load(function(){

    jQuery("html,body").animate({scrollTop: 100}, 1000);

});

It's used for raising errors.

if something:
    raise Exception('My error!')

Here is the official FAQ on installing Python Modules: http://docs.python.org/install/index.html

There are some tips which might help you.

For Laravel 5.4+

'mobile_number_1' => 'required|numeric|min:0|regex:/^[789]\d{9}$/' should do the trick

Use built-in Exception Handling Middleware

Step 1. In your startup, register your exception handling route:

// It should be one of your very first registrations
app.UseExceptionHandler("/error"); // Add this
app.UseEndpoints(endpoints => endpoints.MapControllers());

Step 2. Create controller that will handle all exceptions and produce error response:

[ApiExplorerSettings(IgnoreApi = true)]
public class ErrorsController : ControllerBase
{
    [Route("error")]
    public MyErrorResponse Error()
    {
        var context = HttpContext.Features.Get<IExceptionHandlerFeature>();
        var exception = context.Error; // Your exception
        var code = 500; // Internal Server Error by default

        if      (exception is MyNotFoundException) code = 404; // Not Found
        else if (exception is MyUnauthException)   code = 401; // Unauthorized
        else if (exception is MyException)         code = 400; // Bad Request

        Response.StatusCode = code; // You can use HttpStatusCode enum instead

        return new MyErrorResponse(exception); // Your error model
    }
}

A few important notes and observations:

• [ApiExplorerSettings(IgnoreApi = true)] is needed. Otherwise, it may break your Swashbuckle swagger
• Again, app.UseExceptionHandler("/error"); has to be one of the very top registrations in your Startup Configure(...) method. It's probably safe to place it at the top of the method.
• The path in app.UseExceptionHandler("/error") and in controller [Route("error")] should be the same, to allow the controller handle exceptions redirected from exception handler middleware.

Microsoft documentation for this subject is not that great but has some interesting ideas. I'll just leave the link here.

Response models and custom exceptions

Implement your own response model and exceptions. This example is just a good starting point. Every service would need to handle exceptions in its own way. But with this code, you have full flexibility and control over handling exceptions and returning a proper result to the caller.

An example of error response model (just to give you some ideas):

public class MyErrorResponse
{
    public string Type { get; set; }
    public string Message { get; set; }
    public string StackTrace { get; set; }

    public MyErrorResponse(Exception ex)
    {
        Type = ex.GetType().Name;
        Message = ex.Message;
        StackTrace = ex.ToString();
    }
}

For simpler services, you might want to implement http status code exception that would look like this:

public class HttpStatusException : Exception
{
    public HttpStatusCode Status { get; private set; }

    public HttpStatusException(HttpStatusCode status, string msg) : base(msg)
    {
        Status = status;
    }
}

This can be thrown like that:

throw new HttpStatusCodeException(HttpStatusCode.NotFound, "User not found");

Then your handling code could be simplified to:

if (exception is HttpStatusException httpException)
{
    code = (int) httpException.Status;
}

Why so un-obvious HttpContext.Features.Get<IExceptionHandlerFeature>()?

ASP.NET Core developers embraced the concept of middlewares where different aspects of functionality such as Auth, Mvc, Swagger etc. are separated and executed sequentially by processing the request and returning the response or passing the execution to the next middleware. With this architecture, MVC itself, for instance, would not be able to handle errors happening in Auth. So, they came up with exception handling middleware that catches all the exceptions happening in middlewares registered down in the pipeline, pushes exception data into HttpContext.Features, and re-runs the pipeline for specified route (/error), allowing any middleware to handle this exception, and the best way to handle it is by our Controllers to maintain proper content negotiation.

Based on Mohammed Radwan's answer I came up with the following jQuery solution. Basically what it does is keep track of what iFrame people are hovering. Then if the window blurs that most likely means the user clicked the iframe banner.

the iframe should be put in a div with an id, to make sure you know which iframe the user clicked on:

<div class='banner' bannerid='yyy'>
    <iframe src='http://somedomain.com/whatever.html'></iframe>
<div>

so:

$(document).ready( function() {
    var overiFrame = -1;
    $('iframe').hover( function() {
        overiFrame = $(this).closest('.banner').attr('bannerid');
    }, function() {
        overiFrame = -1
    });

... this keeps overiFrame at -1 when no iFrames are hovered, or the 'bannerid' set in the wrapping div when an iframe is hovered. All you have to do is check if 'overiFrame' is set when the window blurs, like so: ...

    $(window).blur( function() {
        if( overiFrame != -1 )
            $.post('log.php', {id:overiFrame}); /* example, do your stats here */
    });
});

Very elegant solution with a minor downside: if a user presses ALT-F4 when hovering the mouse over an iFrame it will log it as a click. This only happened in FireFox though, IE, Chrome and Safari didn't register it.

Thanks again Mohammed, very useful solution!

If you are using the InternetExplorer.Application COM object, check the ReadyState property for the value of 4.

cout.fill('*');
cout << -12345 << endl; // print default value with no field width
cout << setw(10) << -12345 << endl; // print default with field width
cout << setw(10) << left << -12345 << endl; // print left justified
cout << setw(10) << right << -12345 << endl; // print right justified
cout << setw(10) << internal << -12345 << endl; // print internally justified

This produces the output:

-12345
****-12345
-12345****
****-12345
-****12345

Change the version number to 2.19.1 works for me :)

`<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <systemPropertyVariables>
            <xmlOutputDir>${project.build.directory}/surefire</xmlOutputDir>
        </systemPropertyVariables>
    </configuration>

Try moving the order by clause outside sub select and add the order by field in sub select

SELECT * FROM 

(SELECT COUNT(1) ,refKlinik_id FROM Seanslar WHERE MONTH(tarihi) = 4 GROUP BY refKlinik_id)
as dorduncuay 

ORDER BY refKlinik_id 

Try this.

 var dateAsString = DateTime.Now.ToString("dd/MM/yyyy");
// dateAsString = "09/07/2013"

and also check this link for more formatting data and time

If you use Date objects and then use the getTime() function for both dates it will give you their respective times since Jan 1, 1970 in a number value. You can then get the difference between these numbers.

If that doesn't help you out, check out the complete documentation: http://www.w3schools.com/jsref/jsref_obj_date.asp

On Windows 8.1, using. NET 3.5, I had a similar problem.
Although the name of my file was only 239 characters length when I went to instantiate a FileInfo object with just the file name (without path) occurred an exception of type System. IO.PathTooLongException

I resolved the problem trimming the file name to 204 characters (extension included).

The reason that does not work is because this has no specific meaning inside of an if statement, you will have to go back to a level of scope where this is defined (a function).

For example:

$('#element1').click(function() {
    console.log($(this).attr('id')); // logs "element1"

    if ($('#element2').hasClass('class')) {
        console.log($(this).attr('id')); // still logs "element1"
    }
});

there is a better way.

View.performClick();

http://developer.android.com/reference/android/view/View.html#performClick()

this should answer all your problems. every View inherits this function, including Button, Spinner, etc.

Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View. For example, you can't just call

View.performClick();

Instead, do something like:

View myView = findViewById(R.id.myview);
myView.performClick();

An another way: your application can open a server socet and wait for an information arrived to it. For example a string with a "magic" word :) and then react to make shutdown: System.exit(). You can send such information to the socke using an external application like telnet.

This is an API issue, you won't get this error if using Postman/Fielder to send HTTP requests to API. In case of browsers, for security purpose, they always send OPTIONS request/preflight to API before sending the actual requests (GET/POST/PUT/DELETE). Therefore, in case, the request method is OPTION, not only you need to add "Authorization" into "Access-Control-Allow-Headers", but you need to add "OPTIONS" into "Access-Control-allow-methods" as well. This was how I fixed:

if (context.Request.Method == "OPTIONS")
        {
            context.Response.Headers.Add("Access-Control-Allow-Origin", new[] { (string)context.Request.Headers["Origin"] });
            context.Response.Headers.Add("Access-Control-Allow-Headers", new[] { "Origin, X-Requested-With, Content-Type, Accept, Authorization" });
            context.Response.Headers.Add("Access-Control-Allow-Methods", new[] { "GET, POST, PUT, DELETE, OPTIONS" });
            context.Response.Headers.Add("Access-Control-Allow-Credentials", new[] { "true" });

        }

I had the same error and just wanted to share my solution. In turned out that the minified version of popper had the code in the same line as the comment and so the entire code was commented out. I just pressed enter after the actual comment so the code was on a new line and then it worked fine.

override func viewDidLoad() {
        super.viewDidLoad()

self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tap)))

}

func tap(sender: UITapGestureRecognizer){
        print("tapped")
        view.endEditing(true)
}

Try this,It's Working

A SELECT INTO statement will throw an error if it returns anything other than 1 row. If it returns 0 rows, you'll get a no_data_found exception. If it returns more than 1 row, you'll get a too_many_rows exception. Unless you know that there will always be exactly 1 employee with a salary greater than 3000, you do not want a SELECT INTO statement here.

Most likely, you want to use a cursor to iterate over (potentially) multiple rows of data (I'm also assuming that you intended to do a proper join between the two tables rather than doing a Cartesian product so I'm assuming that there is a departmentID column in both tables)

BEGIN
  FOR rec IN (SELECT EMPLOYEE.EMPID, 
                     EMPLOYEE.ENAME, 
                     EMPLOYEE.DESIGNATION, 
                     EMPLOYEE.SALARY,  
                     DEPARTMENT.DEPT_NAME 
                FROM EMPLOYEE, 
                     DEPARTMENT 
               WHERE employee.departmentID = department.departmentID
                 AND EMPLOYEE.SALARY > 3000)
  LOOP
    DBMS_OUTPUT.PUT_LINE ('Employee Nnumber: ' || rec.EMPID);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Name: ' || rec.ENAME);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Designation: ' || rec.DESIGNATION);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Salary: ' || rec.SALARY);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Department: ' || rec.DEPT_NAME);
  END LOOP;
END;

I'm assuming that you are just learning PL/SQL as well. In real code, you'd never use dbms_output like this and would not depend on anyone seeing data that you write to the dbms_output buffer.

You can find your Arduino via Terminal with

 ls /dev/tty.*

then you can read that serial port using the screen command, like this

screen /dev/tty.[yourSerialPortName] [yourBaudRate]

for example:

screen /dev/tty.usbserial-A6004byf 9600

All you need is to create two layouts:

1. an empty layout

2. main layout

Then write the code below in _viewStart file:

@{
   if (Request.IsAjaxRequest())
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_emptyLayout.cshtml";
   }
   else
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_Layout.cshtml";
   }
 }

of course, maybe it is not the best solution

Reasons you may get a foreign key constraint error:

1. You are not using InnoDB as the engine on all tables.
2. You are trying to reference a nonexistent key on the target table. Make sure it is a key on the other table (it can be a primary or unique key, or just a key)
3. The types of the columns are not the same (exception is the column on the referencing table can be nullable even if it is not nullable on the referenced table).
4. If the PK/FK is a varchar make sure the collation is the same for both.

Update:

5. One of the reasons may also be that the column you are using for ON DELETE SET NULL is not defined to be null. So make sure that the column is set default null.

Check these.

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

In case of Homebrew, mysql would also look for my.cnf in it's Cellar directory, for example:

/usr/local/Cellar/mysql/5.7.21/my.cnf

For the case one prefers to keep the config close to the binaries - create my.cnf here if it's missing.

Restart mysql after change:

brew services restart mysql

You should remove the references to it by assigning null or leaving the block where it was declared. After that, it will be automatically deleted by the garbage collector (not immediately, but eventually).

Example 1:

Object a = new Object();
a = null; // after this, if there is no reference to the object,
          // it will be deleted by the garbage collector

Example 2:

if (something) {
    Object o = new Object(); 
} // as you leave the block, the reference is deleted.
  // Later on, the garbage collector will delete the object itself.

Not something that you are currently looking for, but FYI: you can invoke the garbage collector with the call System.gc()

On my system, I don't have the rename command. Here is a simple one liner. It finds all the HTML files recursively and adds prefix_ in front of their names:

for f in $(find . -name '*.html'); do mv "$f" "$(dirname "$f")/prefix_$(basename "$f")"; done

Use an ArrayList:

alist.remove(1); //removes the element at position 1

For anyone looking for an Angular2 (2.4.8) solution, since this is a generically-popular question when searching:

<div *ngFor="let choice of choices">
  <input type="radio" [checked]="choice == defaultChoice">
</div>

This will add the checked attribute to the input given the condition, but will add nothing if the condition fails.

Do not do this:

[attr.checked]="choice == defaultChoice"

because this will add the attribute checked="false" to every other input element.

Since the browser only looks for the presence of the checked attribute (the key), ignoring its value, so the last input in the group will be checked.

Check out the "encoding/binary" package. Particularly the Read and Write functions:

binary.Write(a, binary.LittleEndian, myInt)

JSONArray jsonArray = new JSONArray(yourJsonString);

for (int i = 0; i < jsonArray.length(); i++) {
     JSONObject obj1 = jsonArray.getJSONObject(i);
     JSONArray results = patient.getJSONArray("results");
     String indexForPhone =  patientProfile.getJSONObject(0).getString("indexForPhone"));
}

Change to JSONArray, then convert to JSONObject.

you can set output format,eg to see only the command and the process id.

ps -eo pid,args

see the man page of ps for more output format. alternatively, you can use the -w or --width n options.

If all else fails, here's another workaround, (just to see your long cmds)

awk '{ split(FILENAME,f,"/") ; printf "%s: %s\n", f[3],$0 }' /proc/[0-9]*/cmdline

As others have said, you cannot change the size of an existing Java array.

ArrayList is the closest that standard Java has to a dynamic sized array. However, there are some things about ArrayList (actually the List interface) that are not "array like". For example:

• You cannot use [ ... ] to index a list. You have to use the get(int) and set(int, E) methods.
• An ArrayList is created with zero elements. You cannot simple create an ArrayList with 20 elements and then call set(15, foo).
• You cannot directly change the size of an ArrayList. You do it indirectly using the various add, insert and remove methods.

If you want something more array-like, you will need to design your own API. (Maybe someone could chime in with an existing third party library ... I couldn't find one with 2 minutes "research" using Google :-) )

If you only really need an array that grows as you are initializing it, then the solution is something like this.

ArrayList<T> tmp = new ArrayList<T>();
while (...) {
    tmp.add(new T(...));
}
// This creates a new array and copies the element of 'tmp' to it.
T[] array = tmp.toArray(new T[tmp.size()]);

std::list<Object> l; 
std::list<Object>::iterator ptr;
int i;

for( i = 0 , ptr = l.begin() ; i < N && ptr != l.end() ; i++ , ptr++ );

if( ptr == l.end() ) {
    // list too short  
} else {
    // 'ptr' points to N-th element of list
}

Find out if an enumerable contains any duplicate :

var anyDuplicate = enumerable.GroupBy(x => x.Key).Any(g => g.Count() > 1);

Find out if all values in an enumerable are unique :

var allUnique = enumerable.GroupBy(x => x.Key).All(g => g.Count() == 1);

Normally when querying a database with SQL and then fill a data-table with its results, it will never be a null Data table. You have the column headers filled with column information even if you returned 0 records.When one tried to process a data table with 0 records but with column information it will throw exception.To check the datatable before processing one could check like this.

if (DetailTable != null && DetailTable.Rows.Count>0)

The arguments that you provide to a bashscript will appear in the variables $1 and $2 and $3 where the number refers to the argument. $0 is the command itself.

The arguments are seperated by spaces, so if you would provide the -from and -to in the command, they will end up in these variables too, so for this:

./ocrscript.sh -from /home/kristoffer/test.png -to /home/kristoffer/test.txt

You'll get:

$0    # ocrscript.sh
$1    # -from
$2    # /home/kristoffer/test.png
$3    # -to
$4    # /home/kristoffer/test.txt

It might be easier to omit the -from and the -to, like:

ocrscript.sh /home/kristoffer/test.png /home/kristoffer/test.txt

Then you'll have:

The downside is that you'll have to supply it in the right order. There are libraries that can make it easier to parse named arguments on the command line, but usually for simple shell scripts you should just use the easy way, if it's no problem.

Then you can do:

/usr/local/bin/abbyyocr9 -rl Swedish -if "$1" -of "$2" 2>&1

The double quotes around the $1 and the $2 are not always necessary but are adviced, because some strings won't work if you don't put them between double quotes.

you could JSONObject#has, providing the key as input and check if the method returns true or false. You could also

use optString instead of getString:

Returns the value mapped by name if it exists, coercing it if necessary. Returns the empty string if no such mapping exists

Just for fun, don't do this!

$.fn.transitiondone = function () {
  return this.each(function () {
    var $this = $(this);
    setTimeout(function () {
      $this.trigger('transitiondone');
    }, (parseFloat($this.css('transitionDelay')) + parseFloat($this.css('transitionDuration'))) * 1000);
  });
};


$('div').on('mousedown', function (e) {
  $(this).addClass('bounce').transitiondone();
});

$('div').on('transitiondone', function () {
  $(this).removeClass('bounce');
});

There you go: (a-zA-Z)

function codeToChar( number ) {
  if ( number >= 0 && number <= 25 ) // a-z
    number = number + 97;
  else if ( number >= 26 && number <= 51 ) // A-Z
    number = number + (65-26);
  else
    return false; // range error
  return String.fromCharCode( number );
}

input: 0-51, or it will return false (range error);

OR:

var codeToChar = function() {
  var abc = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ".split("");
  return function( code ) {
    return abc[code];
  };
})();

returns undefined in case of range error. NOTE: the array will be created only once and because of closure it will be available for the the new codeToChar function. I guess it's even faster then the first method (it's just a lookup basically).

Given your representation, your function is as efficient as can be done. Of course, as noted by others (and as practiced in languages older than Lua), the solution to your real problem is to change representation. When you have tables and you want sets, you turn tables into sets by using the set element as the key and true as the value. +1 to interjay.

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

You can use the patch function for setting defaults with some of the values in your form group.

component.html

<form [formGroup]="countryForm">
    <select id="country" formControlName="country">
        <option *ngFor="let c of countries" [ngValue]="c">{{ c }}</option>
    </select>
</form>

component.ts

import { FormControl, FormGroup, Validators } from '@angular/forms';

export class Component implements OnInit{

    countries: string[] = ['USA', 'UK', 'Canada'];
    default: string = 'UK';

    countryForm: FormGroup;

    constructor() {

        this.countryForm.controls['country'].setValue(this.default, {onlySelf: true});
    }
}

ngOnInit() {
    this.countryForm = new FormGroup({
      'country': new FormControl(null)
    }); 

    this.countryForm.patchValue({
      'country': default
    });

  }

I find git stash very useful for temporal handling of all 'dirty' states.

Facing this problem, I made the following addition to my css stylesheet:

#mainContent .container {
    padding-left:16px;
    padding-right:16px;
}
  #mainContent .row {
    margin-left: -8px;
    margin-right: -8px;
}

  #mainContent .col-xs-1, #mainContent .col-sm-1, #mainContent .col-md-1, #mainContent .col-lg-1, #mainContent .col-xs-2, #mainContent .col-sm-2, #mainContent .col-md-2, #mainContent .col-lg-2, #mainContent .col-xs-3, #mainContent .col-sm-3, #mainContent .col-md-3, #mainContent .col-lg-3, #mainContent .col-xs-4, #mainContent .col-sm-4, #mainContent .col-md-4, #mainContent .col-lg-4, #mainContent .col-xs-5, #mainContent .col-sm-5, #mainContent .col-md-5, #mainContent .col-lg-5, #mainContent .col-xs-6, #mainContent .col-sm-6, #mainContent .col-md-6, #mainContent .col-lg-6, #mainContent .col-xs-7, #mainContent .col-sm-7, #mainContent .col-md-7, #mainContent .col-lg-7, #mainContent .col-xs-8, #mainContent .col-sm-8, #mainContent .col-md-8, #mainContent .col-lg-8, #mainContent .col-xs-9, #mainContent .col-sm-9, #mainContent .col-md-9, #mainContent .col-lg-9, #mainContent .col-xs-10, #mainContent .col-sm-10, #mainContent .col-md-10, #mainContent .col-lg-10, #mainContent .col-xs-11, #mainContent .col-sm-11, #mainContent .col-md-11, #mainContent .col-lg-11, #mainContent .col-xs-12, #mainContent .col-sm-12, #mainContent .col-md-12, #mainContent .col-lg-12 
{
    padding-left: 8px;
    padding-right: 8px;
}

This overrides the default bootstrap styling and makes the left and right sides and the gutter equal width.

Here is how to clear all trash & caches (without other private data in browsers) by a command line. This is a command line batch script that takes care of all trash (as of April 2014):

erase "%TEMP%\*.*" /f /s /q
for /D %%i in ("%TEMP%\*") do RD /S /Q "%%i"

erase "%TMP%\*.*" /f /s /q
for /D %%i in ("%TMP%\*") do RD /S /Q "%%i"

erase "%ALLUSERSPROFILE%\TEMP\*.*" /f /s /q
for /D %%i in ("%ALLUSERSPROFILE%\TEMP\*") do RD /S /Q "%%i"

erase "%SystemRoot%\TEMP\*.*" /f /s /q
for /D %%i in ("%SystemRoot%\TEMP\*") do RD /S /Q "%%i"


@rem Clear IE cache -  (Deletes Temporary Internet Files Only)
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8
erase "%LOCALAPPDATA%\Microsoft\Windows\Tempor~1\*.*" /f /s /q

I am pretty sure it will run for some time when you first run it :) Enjoy!

With

with() is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.

Example:

User > hasMany > Post

$users = User::with('posts')->get();
foreach($users as $user){
    $users->posts; // posts is already loaded and no additional DB query is run
}

Has

has() is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation') that means you only want to get the models that have at least one related model in this relation.

Example:

User > hasMany > Post

$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection

WhereHas

whereHas() works basically the same as has() but allows you to specify additional filters for the related model to check.

Example:

User > hasMany > Post

$users = User::whereHas('posts', function($q){
    $q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned

The primary goal of a hashmap is to store a data set and provide near constant time lookups on it using a unique key. There are two common styles of hashmap implementation:

• Separate chaining: one with an array of buckets (linked lists)
• Open addressing: a single array allocated with extra space so index collisions may be resolved by placing the entry in an adjacent slot.

Separate chaining is preferable if the hashmap may have a poor hash function, it is not desirable to pre-allocate storage for potentially unused slots, or entries may have variable size. This type of hashmap may continue to function relatively efficiently even when the load factor exceeds 1.0. Obviously, there is extra memory required in each entry to store linked list pointers.

Hashmaps using open addressing have potential performance advantages when the load factor is kept below a certain threshold (generally about 0.7) and a reasonably good hash function is used. This is because they avoid potential cache misses and many small memory allocations associated with a linked list, and perform all operations in a contiguous, pre-allocated array. Iteration through all elements is also cheaper. The catch is hashmaps using open addressing must be reallocated to a larger size and rehashed to maintain an ideal load factor, or they face a significant performance penalty. It is impossible for their load factor to exceed 1.0.

Some key performance metrics to evaluate when creating a hashmap would include:

• Maximum load factor
• Average collision count on insertion
• Distribution of collisions: uneven distribution (clustering) could indicate a poor hash function.
• Relative time for various operations: put, get, remove of existing and non-existing entries.

Here is a flexible hashmap implementation I made. I used open addressing and linear probing for collision resolution.

If you have a branch different than master, one easy way is to check out that branch, then check out master. Voila, you are back at the tip of master. There's probably smarter ways...

in your dispatcher servlet context xml, you have to add a propertie "<property name="contentType" value="text/html;charset=UTF-8" />" on your viewResolver bean. we are using freemarker for views.

it looks something like this:

<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
       ...
       <property name="contentType" value="text/html;charset=UTF-8" />
       ...
</bean>

@Adam Just add a function using onClick="getId()"

function getId(){console.log(this.event.target.id)}

Swift 2.0+

Now with Swift 2.0 you can just use Float(Wage.text) which returns a Float? type. More clear than the below solution which just returns 0.

If you want a 0 value for an invalid Float for some reason you can use Float(Wage.text) ?? 0 which will return 0 if it is not a valid Float.

Old Solution

The best way to handle this is direct casting:

var WageConversion = (Wage.text as NSString).floatValue

I actually created an extension to better use this too:

extension String {
    var floatValue: Float {
        return (self as NSString).floatValue
    }
}

Now you can just call var WageConversion = Wage.text.floatValue and allow the extension to handle the bridge for you!

This is a good implementation since it can handle actual floats (input with .) and will also help prevent the user from copying text into your input field (12p.34, or even 12.12.41).

Obviously, if Apple does add a floatValue to Swift this will throw an exception, but it may be nice in the mean time. If they do add it later, then all you need to do to modify your code is remove the extension and everything will work seamlessly, since you will already be calling .floatValue!

Also, variables and constants should start with a lower case (including IBOutlets)

If you have more than one enviroment, you may add the following way in the angular.json:

 "serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "browserTarget": "your_project:build"
      },
      "configurations": {
        "production": {
          "browserTarget": "your_project:build:production"
        },
        "es5": {
          "browserTarget": "your_project:build:es5"
        },
        "local": {
          "browserTarget": "your_project:build:local",
          "port": 4201
        },
        "uat": {
          "browserTarget": "your_project:build:uat"
        }
      }
    },

This way only the local points to another port.

I recommend GitHub: Array sortBy - a best implementation of sortBy method which uses the Schwartzian transform

But for now we are going to try this approach Gist: sortBy-old.js.
Let's create a method to sort arrays being able to arrange objects by some property.

Creating the sorting function

var sortBy = (function () {
  var toString = Object.prototype.toString,
      // default parser function
      parse = function (x) { return x; },
      // gets the item to be sorted
      getItem = function (x) {
        var isObject = x != null && typeof x === "object";
        var isProp = isObject && this.prop in x;
        return this.parser(isProp ? x[this.prop] : x);
      };
      
  /**
   * Sorts an array of elements.
   *
   * @param {Array} array: the collection to sort
   * @param {Object} cfg: the configuration options
   * @property {String}   cfg.prop: property name (if it is an Array of objects)
   * @property {Boolean}  cfg.desc: determines whether the sort is descending
   * @property {Function} cfg.parser: function to parse the items to expected type
   * @return {Array}
   */
  return function sortby (array, cfg) {
    if (!(array instanceof Array && array.length)) return [];
    if (toString.call(cfg) !== "[object Object]") cfg = {};
    if (typeof cfg.parser !== "function") cfg.parser = parse;
    cfg.desc = !!cfg.desc ? -1 : 1;
    return array.sort(function (a, b) {
      a = getItem.call(cfg, a);
      b = getItem.call(cfg, b);
      return cfg.desc * (a < b ? -1 : +(a > b));
    });
  };
  
}());

Setting unsorted data

var data = [
  {date: "2011-11-14T17:25:45Z", quantity: 2, total: 200, tip: 0,   type: "cash"},
  {date: "2011-11-14T16:28:54Z", quantity: 1, total: 300, tip: 200, type: "visa"},
  {date: "2011-11-14T16:30:43Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T17:22:59Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:53:41Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:48:46Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-31T17:29:52Z", quantity: 1, total: 200, tip: 100, type: "visa"},
  {date: "2011-11-01T16:17:54Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T16:58:03Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:20:19Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T17:07:21Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:54:06Z", quantity: 1, total: 100, tip: 0,   type: "cash"}
];

Using it

Finally, we arrange the array, by "date" property as string

//sort the object by a property (ascending)
//sorting takes into account uppercase and lowercase
sortBy(data, { prop: "date" });

If you want to ignore letter case, set the "parser" callback:

//sort the object by a property (descending)
//sorting ignores uppercase and lowercase
sortBy(data, {
    prop: "date",
    desc: true,
    parser: function (item) {
        //ignore case sensitive
        return item.toUpperCase();
    }
});

If you want to treat the "date" field as Date type:

//sort the object by a property (ascending)
//sorting parses each item to Date type
sortBy(data, {
    prop: "date",
    parser: function (item) {
        return new Date(item);
    }
});

Here you can play with the above example:
jsbin.com/lesebi

Try the vim-way:

ex -s +"g/foo/d" -cwq file.txt

This can be done by using unlist before as.vector. The result is the same as using the parameter use.names=FALSE.

as.vector(unlist(myList))

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

I do not want to repeat others' answers, so, in short I explain some common misunderstanding

• Practical resource: PATTERNS, PRINCIPLES, AND PRACTICES OF DOMAIN-DRIVEN DESIGN by Scott Millett
• It is a methodology for complicated business systems. It takes all the technical matters out when communicating with business experts
• It provides an extensive understanding of (simplified and distilled model of) business across the whole dev team.
• it keeps business model in sync with code model by using ubiquitous language (the language understood by the whole dev team, business experts, business analysts, ...), which is used for communication within the dev team or dev with other teams
• It has nothing to do with Project Management. Although it can be perfectly used in project management methods like Agile.

• You should avoid using it all across your project

  DDD stresses the need to focus the most effort on the core subdomain. The core subdomain is the area of your product that will be the difference between it being a success and it being a failure. It’s the product’s unique selling point, the reason it is being built rather than bought.

  Basically, it is because it takes too much time and effort. So, it is suggested to break down the whole domain into subdomain and just apply it in those with high business value. (ex not in generic subdomain like email, ...)

• It is not object oriented programming. It is mostly problem solving approach and (sometimes) you do not need to use OO patterns (such as Gang of Four) in your domain models. Simply because it can not be understood by Business Experts (they do not know much about Factory, Decorator, ...). There are even some patterns in DDD (such as The Transaction Script, Table Module) which are not 100% in line with OO concepts.

The Best & Easiest solution:-

 SELECT
    max(salary)
FROM
    salary
WHERE
    salary < (
        SELECT
            max(salary)
        FROM
            salary
    );

For latest users using Android studio 3.0.1 or above. Simply click Alt + Enter and upgrade your language level to 8.0 - Lambdas, type annotations etc.

item=sp.getItemAtPosition(i).toString();
list.add(item);
adapter.notifyDataSetChanged () ;

look up ArrayAdapter.notifyDataSetChanged()

I think it's better to always use ApplicationContext, unless you're in a mobile environment like someone else said already. ApplicationContext has more functionality and you definitely want to use the PostProcessors such as RequiredAnnotationBeanPostProcessor, AutowiredAnnotationBeanPostProcessor and CommonAnnotationBeanPostProcessor, which will help you simplify your Spring configuration files, and you can use annotations such as @Required, @PostConstruct, @Resource, etc in your beans.

Even if you don't use all the stuff ApplicationContext offers, it's better to use it anyway, and then later if you decide to use some resource stuff such as messages or post processors, or the other schema to add transactional advices and such, you will already have an ApplicationContext and won't need to change any code.

If you're writing a standalone app, load the ApplicationContext in your main method, using a ClassPathXmlApplicationContext, and get the main bean and invoke its run() (or whatever method) to start your app. If you're writing a web app, use the ContextLoaderListener in web.xml so that it creates the ApplicationContext and you can later get it from the ServletContext, regardless of whether you're using JSP, JSF, JSTL, struts, Tapestry, etc.

Also, remember you can use multiple Spring configuration files and you can either create the ApplicationContext by listing all the files in the constructor (or listing them in the context-param for the ContextLoaderListener), or you can just load a main config file which has import statements. You can import a Spring configuration file into another Spring configuration file by using <import resource="otherfile.xml" /> which is very useful when you programmatically create the ApplicationContext in the main method and load only one Spring config file.

Set the main div CSS to somthing like:

<style>
    .wrapper{
        display:flex;
        flex-direction: column;
    }
</style>

<div id="wrapper">
        <div id="inner1">This is inner div 1</div>
        <div id="inner2">This is inner div 2</div>
</div>

• hashtag # parts were manually used in the above example just for illustration purposes, however, server-side languages (including php) can't natively detect them (Only Javascript can do that, as hashtag is only browser/client side functionality ).
• DIRECTORY_SEPARATOR returns \ for Windows-type hosting, instead of /.

For WordPress

//(let's say, if wordpress is installed in subdirectory:  http://example.com/wpdir/)
home_url()                       http://example.com/wpdir/        //if is_ssl() is true, then it will be "https"
get_stylesheet_directory_uri()   http://example.com/wpdir/wp-content/themes/THEME_NAME  [same: get_bloginfo('template_url') ]
get_stylesheet_directory()       /home/user/public_html/wpdir/wp-content/themes/THEME_NAME
plugin_dir_url(__FILE__)         http://example.com/wpdir/wp-content/themes/PLUGIN_NAME
plugin_dir_path(__FILE__)        /home/user/public_html/wpdir/wp-content/plugins/PLUGIN_NAME/  

In your particular example perhaps you do not have to perform any checks at all. Is that possible that New-Object return null? I have never seen that. The command should fail in case of a problem and the rest of the code in the example will not be executed. So why should we do that checks at all?

Only in the code like below we need some checks (explicit comparison with $null is the best):

# we just try to get a new object
$ie = $null
try {
    $ie = New-Object -ComObject InternetExplorer.Application
}
catch {
    Write-Warning $_
}

# check and continuation
if ($ie -ne $null) {
    ...
}

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

You seem to be confusing client-side and server side code. When the button is clicked you need to send (post, get) the variables to the server where the php can be executed. You can either submit the page or use an ajax call to submit just the data. -don

At the risk of beating a dead horse... I find this most useful in traversing nested objects to reference where you're at with respect to the base object or to a similar object with the same structure. To that end, this is useful with a nested object traversal function. Note that I've used an array to hold the path. It would be trivial to modify this to use either a string path or an array. Also note that you can assign "undefined" to the value, unlike some of the other implementations.

/*_x000D_
 * Traverse each key in a nested object and call fn(curObject, key, value, baseObject, path)_x000D_
 * on each. The path is an array of the keys required to get to curObject from_x000D_
 * baseObject using objectPath(). If the call to fn() returns falsey, objects below_x000D_
 * curObject are not traversed. Should be called as objectTaverse(baseObject, fn)._x000D_
 * The third and fourth arguments are only used by recursion._x000D_
 */_x000D_
function objectTraverse (o, fn, base, path) {_x000D_
    path = path || [];_x000D_
    base = base || o;_x000D_
    Object.keys(o).forEach(function (key) {_x000D_
        if (fn(o, key, o[key], base, path) && jQuery.isPlainObject(o[key])) {_x000D_
            path.push(key);_x000D_
            objectTraverse(o[key], fn, base, path);_x000D_
            path.pop();_x000D_

    var last = path.pop();_x000D_

doc.id gets the UID.

Combine with the rest of the data for one object like so:

Object.assign({ uid: doc.id }, doc.data())

In newer versions change was made to the flags: from the documentation:

--extended-insert, -e

Write INSERT statements using multiple-row syntax that includes several VALUES lists. This results in a smaller dump file and speeds up inserts when the file is reloaded.

--opt

This option, enabled by default, is shorthand for the combination of --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset. It gives a fast dump operation and produces a dump file that can be reloaded into a MySQL server quickly.

Because the --opt option is enabled by default, you only specify its converse, the --skip-opt to turn off several default settings. See the discussion of mysqldump option groups for information about selectively enabling or disabling a subset of the options affected by --opt.

--skip-extended-insert

Turn off extended-insert

For transitions you can use the following to detect the end of a transition via jQuery:

$("#someSelector").bind("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){ ... });

Mozilla has an excellent reference:

https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions#Detecting_the_start_and_completion_of_a_transition

For animations it's very similar:

$("#someSelector").bind("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd", function(){ ... });

Note that you can pass all of the browser prefixed event strings into the bind() method simultaneously to support the event firing on all browsers that support it.

Update:

Per the comment left by Duck: you use jQuery's .one() method to ensure the handler only fires once. For example:

$("#someSelector").one("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){ ... });

$("#someSelector").one("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd", function(){ ... });

Update 2:

jQuery bind() method has been deprecated, and on() method is preferred as of jQuery 1.7. bind()

You can also use off() method on the callback function to ensure it will be fired only once. Here is an example which is equivalent to using one() method:

$("#someSelector")
.on("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd",
 function(e){
    // do something here
    $(this).off(e);
 });

References:

• .off()

• .one()

Just like with nextSibling and nextElementSibling, just remember that, properties with "element" in their name always returns Element or null. Properties without can return any other kind of node.

console.log(document.body.parentNode, "is body's parent node");    // returns <html>
console.log(document.body.parentElement, "is body's parent element"); // returns <html>

var html = document.body.parentElement;
console.log(html.parentNode, "is html's parent node"); // returns document
console.log(html.parentElement, "is html's parent element"); // returns null

OOP and FP have different goals. OOP aims to encapsulate the complexities/moving parts of software components and FP aims to minimize the complexity and dependencies of software components.

However these two paradigms are not necessarily 100% contradicting and could be applied together to get the benefit from both worlds.

Even with a language that does not natively support functional programming like C#, you could write functional code if you understand the FP principles. Likewise you could apply OOP principles using F# if you understand OOP principles, patterns, and best practices. You would make the right choice based on the situation and problem that you try to solve, regardless of the programming language you use.

With ECMAScript 6, you can use variable property names with the object literal syntax, like this:

var keyName = 'myKey';
var obj = {
              [keyName]: 1
          };
obj.myKey;//1

This syntax is available in the following newer browsers:

Edge 12+ (No IE support), FF34+, Chrome 44+, Opera 31+, Safari 7.1+

(https://kangax.github.io/compat-table/es6/)

You can add support to older browsers by using a transpiler such as babel. It is easy to transpile an entire project if you are using a module bundler such as rollup or webpack.

use .loc instead of apply.

it improves vectorization.

.loc works in simple manner, mask rows based on the condition, apply values to the freeze rows.

Use an OrderedDict. This will ensure that the order is preserved

>>> ''.join(OrderedDict.fromkeys( "aaabcabccd").keys())
'abcd'

PS: I just timed both the OrderedDict and Set solution, and the later is faster. If order does not matter, set should be the natural solution, if Order Matter;s this is how you should do.

>>> from timeit import Timer
>>> t1 = Timer(stmt=stmt1, setup="from __main__ import data, OrderedDict")
>>> t2 = Timer(stmt=stmt2, setup="from __main__ import data")
>>> t1.timeit(number=1000)

Everything is mirrored on omapzoom.org. Some of the code is also mirrored on github.

Contacts is here for example.

Since December 2019, you can use the new official public code search tool for AOSP: cs.android.com. There's also the Android official source browser (based on Gitiles) has a web view of many of the different parts that make up android. Some of the projects (such as Kernel) have been removed and it now only points you to clonable git repositories.

To get all the code locally, you can use the repo helper program, or you can just clone individual repositories.

And others:

• Downloading the Source Tree

Apart from www.json.org you can also implement your own parser using javacc and matching your personnal grammar/schema. See this note on my blog : http://plindenbaum.blogspot.com/2008/07/parsing-json-with-javacc-my-notebook.html

With LESS the actual mixin is in vendor-prefixes.less

.placeholder(@color: @input-color-placeholder) {
...
}

This mixin is called in forms.less on line 133:

.placeholder();

Your solution in LESS is:

.placeholder(#fff);

Imho the best way to go. Just use Winless or a composer compiler like Gulp/Grunt works, too and even better/faster.

pip install opencv-python

or

pip install opencv-python3 

will definately works fine

you have to put your 'system variable' on the java classpath.

You don't need to download any new software. You can use Octave Online to open .m files.

Great question @aryaxt -- you can tell it was a great question because you asked it 5 years ago and I stumbled upon it today trying to find the answer!

I just tried to edit the accepted answer to include this, but in case my edit does not make it in:

If your table was not that large, and assuming your primary key was an auto-incrementing integer you could do something like this:

SELECT 
  table.*
FROM table
--be able to take out dupes later
LEFT JOIN (
  SELECT field, MAX(id) as id
  FROM table
  GROUP BY field
) as noDupes on noDupes.id = table.id
WHERE
  //this will result in only the last instance being seen
  noDupes.id is not NULL

Here is one good article to illustrate the difference among bind(), apply() and call(), summarize it as below.

• bind() allows us to easily set which specific object will be bound to this when a function or method is invoked.

  // This data variable is a global variable?
  var data = [
      {name:"Samantha", age:12},
      {name:"Alexis", age:14}
  ]
  var user = {
      // local data variable?
      data    :[
          {name:"T. Woods", age:37},
          {name:"P. Mickelson", age:43}
      ],
      showData:function (event) {
          var randomNum = ((Math.random () * 2 | 0) + 1) - 1; // random number between 0 and 1?
          console.log (this.data[randomNum].name + " " + this.data[randomNum].age);
      }
  }
  
  // Assign the showData method of the user object to a variable?
  var showDataVar = user.showData;
  showDataVar (); // Samantha 12 (from the global data array, not from the local data array)?
  /*
  This happens because showDataVar () is executed as a global function and use of this inside 
  showDataVar () is bound to the global scope, which is the window object in browsers.
  */
  
  // Bind the showData method to the user object?
  var showDataVar = user.showData.bind (user);
  // Now the we get the value from the user object because the this keyword is bound to the user object?
  showDataVar (); // P. Mickelson 43?
  

• bind() allow us to borrow methods

  // Here we have a cars object that does not have a method to print its data to the console?
  var cars = {
      data:[
         {name:"Honda Accord", age:14},
         {name:"Tesla Model S", age:2}
     ]
  }
  
  // We can borrow the showData () method from the user object we defined in the last example.?
  // Here we bind the user.showData method to the cars object we just created.?
  cars.showData = user.showData.bind (cars);
  cars.showData (); // Honda Accord 14?
  

  One problem with this example is that we are adding a new method showData on the cars object and we might not want to do that just to borrow a method because the cars object might already have a property or method name showData. We don’t want to overwrite it accidentally. As we will see in our discussion of Apply and Call below, it is best to borrow a method using either the Apply or Call method.

• bind() allow us to curry a function

  Function Currying, also known as partial function application, is the use of a function (that accept one or more arguments) that returns a new function with some of the arguments already set.

  function greet (gender, age, name) {
      // if a male, use Mr., else use Ms.?
      var salutation = gender === "male" ? "Mr. " : "Ms. ";
      if (age > 25) {
          return "Hello, " + salutation + name + ".";
      }else {
          return "Hey, " + name + ".";
      }
   }
  

  We can use bind() to curry this greet function

  // So we are passing null because we are not using the "this" keyword in our greet function.
  var greetAnAdultMale = greet.bind (null, "male", 45);
  
  greetAnAdultMale ("John Hartlove"); // "Hello, Mr. John Hartlove."
  
  var greetAYoungster = greet.bind (null, "", 16);
  greetAYoungster ("Alex"); // "Hey, Alex."?
  greetAYoungster ("Emma Waterloo"); // "Hey, Emma Waterloo."
  

• apply() or call() to set this value

  The apply, call, and bind methods are all used to set the this value when invoking a method, and they do it in slightly different ways to allow use direct control and versatility in our JavaScript code.

  The apply and call methods are almost identical when setting the this value except that you pass the function parameters to apply () as an array, while you have to list the parameters individually to pass them to the call () method.

  Here is one example to use call or apply to set this in the callback function.

  // Define an object with some properties and a method?
  // We will later pass the method as a callback function to another function?
  var clientData = {
      id: 094545,
      fullName: "Not Set",
      // setUserName is a method on the clientData object?
      setUserName: function (firstName, lastName)  {
          // this refers to the fullName property in this object?
          this.fullName = firstName + " " + lastName;
      }
  };
  
  function getUserInput (firstName, lastName, callback, callbackObj) {
       // The use of the Apply method below will set the "this" value to callbackObj?
       callback.apply (callbackObj, [firstName, lastName]);
  }
  
  // The clientData object will be used by the Apply method to set the "this" value?
  getUserInput ("Barack", "Obama", clientData.setUserName, clientData);
  // the fullName property on the clientData was correctly set?
  console.log (clientData.fullName); // Barack Obama
  

• Borrow functions with apply or call

  • Borrow Array methods

    Let’s create an array-like object and borrow some array methods to operate on the our array-like object.

    // An array-like object: note the non-negative integers used as keys?
    var anArrayLikeObj = {0:"Martin", 1:78, 2:67, 3:["Letta", "Marieta", "Pauline"], length:4 };
    
     // Make a quick copy and save the results in a real array:
     // First parameter sets the "this" value?
     var newArray = Array.prototype.slice.call (anArrayLikeObj, 0);
     console.log (newArray); // ["Martin", 78, 67, Array[3]]?
    
     // Search for "Martin" in the array-like object?
     console.log (Array.prototype.indexOf.call (anArrayLikeObj, "Martin") === -1 ? false : true); // true?
    

    Another common case is that convert arguments to array as following

      // We do not define the function with any parameters, yet we can get all the arguments passed to it?
     function doSomething () {
        var args = Array.prototype.slice.call (arguments);
        console.log (args);
     }
    
     doSomething ("Water", "Salt", "Glue"); // ["Water", "Salt", "Glue"]
    

  • Borrow other methods

    var gameController = {
         scores  :[20, 34, 55, 46, 77],
         avgScore:null,
         players :[
              {name:"Tommy", playerID:987, age:23},
              {name:"Pau", playerID:87, age:33}
         ]
     }
     var appController = {
         scores  :[900, 845, 809, 950],
         avgScore:null,
         avg     :function () {
                 var sumOfScores = this.scores.reduce (function (prev, cur, index, array) {
                      return prev + cur;
             });
             this.avgScore = sumOfScores / this.scores.length;
         }
       }
       // Note that we are using the apply () method, so the 2nd argument has to be an array?
       appController.avg.apply (gameController);
       console.log (gameController.avgScore); // 46.4?
       // appController.avgScore is still null; it was not updated, only gameController.avgScore was updated?
       console.log (appController.avgScore); // null?
    

• Use apply() to execute variable-arity function

The Math.max is one example of variable-arity function,

// We can pass any number of arguments to the Math.max () method?
console.log (Math.max (23, 11, 34, 56)); // 56

But what if we have an array of numbers to pass to Math.max? We cannot do this:

var allNumbers = [23, 11, 34, 56];
// We cannot pass an array of numbers to the the Math.max method like this?
console.log (Math.max (allNumbers)); // NaN

This is where the apply () method helps us execute variadic functions. Instead of the above, we have to pass the array of numbers using apply () thus:

var allNumbers = [23, 11, 34, 56];
// Using the apply () method, we can pass the array of numbers:
console.log (Math.max.apply (null, allNumbers)); // 56

In a Rails 2.3 app it is just ./script/server start

The answer is: you can't only through sms, i have tried that approach before.

You could fetch the base station IDs, but this won't help you a lot without the location of the base station itself and this informations are really hard to retrieve from the providers.

I have looked through the 3 apps you have listed in your question:

1. The App uses WiFi and GPRS location service, quite the same approach as Google uses on the phone. phonesavvy maybe has a base station location database or uses a database retrieved e.g. from OpenStreetMap or some similar crowd-based project.
2. The app analyzes just the number for country code and city code. No location there.
3. Dito.

SQL Server 2008 R2:

For an existing database that you wish to "restore: from a backup of a different database follow these steps:

1. From the toolbar, click the Activity Monitor button.
2. Click processes. Filter by the database you want to restore. Kill all running processes by right clicking on each process and selecting "kill process".
3. Right click on the database you wish to restore, and select Tasks-->Restore-->From Database.
4. Select the "From Device:" radio button.
5. Select ... and choose the backup file of the other database you wish to restore from.
6. Select the backup set you wish to restore from by selecting the check box to the left of the backup set.
7. Select "Options".
8. Select Overwrite the existing database (WITH REPLACE)
9. Important: Change the "Restore As" Rows Data file name to the file name of the existing database you wish to overwrite or just give it a new name.
10. Do the same with the log file file name.
11. Verify from the Activity Monitor Screen that no new processes were spawned. If they were, kill them.
12. Click OK.

Here is another method using MVC tools which you can handle requests to bad controller names, bad route names, and any other criteria you see fit inside of an Action method. Personally, I prefer to avoid as many web.config settings as possible, because they do the 302 / 200 redirect and do not support ResponseRewrite (Server.Transfer) using Razor views. I'd prefer to return a 404 with a custom error page for SEO reasons.

Some of this is new take on cottsak's technique above.

This solution also uses minimal web.config settings favoring the MVC 3 Error Filters instead.

Usage

Just throw a HttpException from an action or custom ActionFilterAttribute.

Throw New HttpException(HttpStatusCode.NotFound, "[Custom Exception Message Here]")

Step 1

Add the following setting to your web.config. This is required to use MVC's HandleErrorAttribute.

<customErrors mode="On" redirectMode="ResponseRedirect" />

Step 2

Add a custom HandleHttpErrorAttribute similar to the MVC framework's HandleErrorAttribute, except for HTTP errors:

<AttributeUsage(AttributeTargets.All, AllowMultiple:=True)>
Public Class HandleHttpErrorAttribute
    Inherits FilterAttribute
    Implements IExceptionFilter

    Private Const m_DefaultViewFormat As String = "ErrorHttp{0}"

    Private m_HttpCode As HttpStatusCode
    Private m_Master As String
    Private m_View As String

    Public Property HttpCode As HttpStatusCode
        Get
            If m_HttpCode = 0 Then
                Return HttpStatusCode.NotFound
            End If
            Return m_HttpCode
        End Get
        Set(value As HttpStatusCode)
            m_HttpCode = value
        End Set
    End Property

    Public Property Master As String
        Get
            Return If(m_Master, String.Empty)
        End Get
        Set(value As String)
            m_Master = value
        End Set
    End Property

    Public Property View As String
        Get
            If String.IsNullOrEmpty(m_View) Then
                Return String.Format(m_DefaultViewFormat, Me.HttpCode)
            End If
            Return m_View
        End Get
        Set(value As String)
            m_View = value
        End Set
    End Property

    Public Sub OnException(filterContext As System.Web.Mvc.ExceptionContext) Implements System.Web.Mvc.IExceptionFilter.OnException
        If filterContext Is Nothing Then Throw New ArgumentException("filterContext")

        If filterContext.IsChildAction Then
            Return
        End If

        If filterContext.ExceptionHandled OrElse Not filterContext.HttpContext.IsCustomErrorEnabled Then
            Return
        End If

        Dim ex As HttpException = TryCast(filterContext.Exception, HttpException)
        If ex Is Nothing OrElse ex.GetHttpCode = HttpStatusCode.InternalServerError Then
            Return
        End If

        If ex.GetHttpCode <> Me.HttpCode Then
            Return
        End If

        Dim controllerName As String = filterContext.RouteData.Values("controller")
        Dim actionName As String = filterContext.RouteData.Values("action")
        Dim model As New HandleErrorInfo(filterContext.Exception, controllerName, actionName)

        filterContext.Result = New ViewResult With {
            .ViewName = Me.View,
            .MasterName = Me.Master,
            .ViewData = New ViewDataDictionary(Of HandleErrorInfo)(model),
            .TempData = filterContext.Controller.TempData
        }
        filterContext.ExceptionHandled = True
        filterContext.HttpContext.Response.Clear()
        filterContext.HttpContext.Response.StatusCode = Me.HttpCode
        filterContext.HttpContext.Response.TrySkipIisCustomErrors = True
    End Sub
End Class

Step 3

Add Filters to the GlobalFilterCollection (GlobalFilters.Filters) in Global.asax. This example will route all InternalServerError (500) errors to the Error shared view (Views/Shared/Error.vbhtml). NotFound (404) errors will be sent to ErrorHttp404.vbhtml in the shared views as well. I've added a 401 error here to show you how this can be extended for additional HTTP error codes. Note that these must be shared views, and they all use the System.Web.Mvc.HandleErrorInfo object as a the model.

filters.Add(New HandleHttpErrorAttribute With {.View = "ErrorHttp401", .HttpCode = HttpStatusCode.Unauthorized})
filters.Add(New HandleHttpErrorAttribute With {.View = "ErrorHttp404", .HttpCode = HttpStatusCode.NotFound})
filters.Add(New HandleErrorAttribute With {.View = "Error"})

Step 4

Create a base controller class and inherit from it in your controllers. This step allows us to handle unknown action names and raise the HTTP 404 error to our HandleHttpErrorAttribute.

Public Class BaseController
    Inherits System.Web.Mvc.Controller

    Protected Overrides Sub HandleUnknownAction(actionName As String)
        Me.ActionInvoker.InvokeAction(Me.ControllerContext, "Unknown")
    End Sub

    Public Function Unknown() As ActionResult
        Throw New HttpException(HttpStatusCode.NotFound, "The specified controller or action does not exist.")
        Return New EmptyResult
    End Function
End Class

Step 5

Create a ControllerFactory override, and override it in your Global.asax file in Application_Start. This step allows us to raise the HTTP 404 exception when an invalid controller name has been specified.

Public Class MyControllerFactory
    Inherits DefaultControllerFactory

    Protected Overrides Function GetControllerInstance(requestContext As System.Web.Routing.RequestContext, controllerType As System.Type) As System.Web.Mvc.IController
        Try
            Return MyBase.GetControllerInstance(requestContext, controllerType)
        Catch ex As HttpException
            Return DependencyResolver.Current.GetService(Of BaseController)()
        End Try
    End Function
End Class

'In Global.asax.vb Application_Start:

controllerBuilder.Current.SetControllerFactory(New MyControllerFactory)

Step 6

Include a special route in your RoutTable.Routes for the BaseController Unknown action. This will help us raise a 404 in the case where a user accesses an unknown controller, or unknown action.

'BaseController
routes.MapRoute( _
    "Unknown", "BaseController/{action}/{id}", _
    New With {.controller = "BaseController", .action = "Unknown", .id = UrlParameter.Optional} _
)

Summary

This example demonstrated how one can use the MVC framework to return 404 Http Error Codes to the browser without a redirect using filter attributes and shared error views. It also demonstrates showing the same custom error page when invalid controller names and action names are specified.

I'll add a screenshot of an invalid controller name, action name, and a custom 404 raised from the Home/TriggerNotFound action if I get enough votes to post one =). Fiddler returns a 404 message when I access the following URLs using this solution:

/InvalidController
/Home/InvalidRoute
/InvalidController/InvalidRoute
/Home/TriggerNotFound

I don't think it is a bug, Try adding the MIME type to your .htaccess file For instance, put or add the following content to your .htaccess file (which should be in the same place of your .js or above folders)

#JavaScript
AddType application/x-javascript .js

This solved my tree "Resource interpreted as other but transfered ... " warnings. Everytime you have that kind of warning it means you don't have enough info in your .htaccess file.

BTW1: Since you are modifying .htaccess file, make sure you restart your server.

BTW2: I also could clear same warnings for GIF files in Safari 4 with this:

#GIF
AddType image/gif .gif

BTW3: For other file types: see w3schools list or htaccess-guide

You did not specify the database engine in question; in Oracle, an option is to use tuples like this:

SELECT * FROM table WHERE (Col, 1) IN ((123,1),(123,1),(222,1),....)

This ugly hack only works in Oracle SQL, see https://asktom.oracle.com/pls/asktom/asktom.search?tag=limit-and-conversion-very-long-in-list-where-x-in#9538075800346844400

However, a much better option is to use stored procedures and pass the values as an array.

Solution to the original question

You called a non-static method statically. To make a public function static in the model, would look like this:

public static function {
  
}

In General:

Post::get()

In this particular instance:

Post::take(2)->get()

One thing to be careful of, when defining relationships and scope, that I had an issue with that caused a 'non-static method should not be called statically' error is when they are named the same, for example:

public function category(){
    return $this->belongsTo('App\Category');
}

public function scopeCategory(){
    return $query->where('category', 1);
}

When I do the following, I get the non-static error:

Event::category()->get();

The issue, is that Laravel is using my relationship method called category, rather than my category scope (scopeCategory). This can be resolved by renaming the scope or the relationship. I chose to rename the relationship:

public function cat(){
    return $this->belongsTo('App\Category', 'category_id');
}

Please observe that I defined the foreign key (category_id) because otherwise Laravel would have looked for cat_id instead, and it wouldn't have found it, as I had defined it as category_id in the database.

 String strWebData="html...." //**Your html string**

 WebView webDetail=(WebView) findViewById(R.id.webView1);

 WebSettings websetting = webDetail.getSettings();

 websetting.setDefaultTextEncodingName("utf-8");

 webDetail.loadData(strWebData, "text/html; charset=utf-8", null);

Try Editra It's free, has a lot of cool features and plug-ins, it runs on most platforms, and it is written in Python. I use it for all my non-XCode development at home and on Windows/Linux at work.

I think you should be able to use a default route handler and redirect from there to a page outside the app, as detailed below:

const ROUTER_INSTANCE = new VueRouter({
    mode: "history",
    routes: [
        { path: "/", component: HomeComponent },
        // ... other routes ...
        // and finally the default route, when none of the above matches:
        { path: "*", component: PageNotFound }
    ]
})

In the above PageNotFound component definition, you can specify the actual redirect, that will take you out of the app entirely:

Vue.component("page-not-found", {
    template: "",
    created: function() {
        // Redirect outside the app using plain old javascript
        window.location.href = "/my-new-404-page.html";
    }
}

You may do it either on created hook as shown above, or mounted hook also.

Please note:

1. I have not verified the above. You need to build a production version of app, ensure that the above redirect happens. You cannot test this in vue-cli as it requires server side handling.

2. Usually in single page apps, server sends out the same index.html along with app scripts for all route requests, especially if you have set <base href="/">. This will fail for your /404-page.html unless your server treats it as a special case and serves the static page.

Let me know if it works!

Update for Vue 3 onward:

You'll need to replace the '*' path property with '/:pathMatch(.*)*' if you're using Vue 3 as the old catch-all path of '*' is no longer supported. The route would then look something like this:

{ path: '/:pathMatch(.*)*', component: PathNotFound },

See the docs for more info on this update.

I had a similar problem. Using a freeware utility called Unlocker (version 1.9.2), I found that my antivirus software (Panda free) had left a hanging lock on the executable file even though it didn't detect any threat. Unlocker was able to unlock it.

It's an old question. I would like to answer it using new tools.

Minimal working example. Copy it to the python shell and get the result.

from PyQt5.QtWidgets import QApplication
app = QApplication([])
screen = app.primaryScreen()
screenshot = screen.grabWindow(QApplication.desktop().winId())
screenshot.save('/tmp/screenshot.png')

AFAIK Android doesn't support vCard files out of the Box at least not until 2.2.

You could use the app vCardIO to read vcf files from your SD card and save to you contacts. So you have to save them on your SD card in the first place and import them afterwards.

vCardIO is also available trough the market.

I was afraid of adding another library to my thick project, but it's just easy and fast and smart and awesome. Plus, it plays nice with existing code, to some extent.

This was OK for me:

this.conn = (Connection)DriverManager
    .getConnection(url + dbName + "?useSSL=false", userName, password);

you can use @UniqueConstraint on class level, for combined primary key in a table. for example:

 @Entity
 @Table(name = "PRODUCT_ATTRIBUTE", uniqueConstraints = {
       @UniqueConstraint(columnNames = {"PRODUCT_ID"}) })

public class ProductAttribute{}

You have set #slider as absolute, which means that it "is positioned relative to the nearest positioned ancestor" (confusing, right?). Meanwhile, #content div is placed relative, which means "relative to its normal position". So the position of the 2 divs is not related.

You can read about CSS positioning here

If you set both to relative, the divs will be one after the other, as shown here:

#slider {
    position:relative;
    left:0;
    height:400px;

    border-style:solid;
    border-width:5px;
}
#slider img {
    width:100%;
}

#content {
    position:relative;
}

#content #text {
    position:relative;
    width:950px;
    height:215px;
    color:red;
}

Your problem has nothing to do with encodings, it's a simple matter of understanding basic C++. You are returning a pointer to a local variable from your function, which will have gone out of scope by the time anyone can use it, thus creating undefined behaviour (i.e. a programming error).

Follow this Golden Rule: "If you are using naked char pointers, you're Doing It Wrong. (Except for when you aren't.)"

I've previously posted some code to do the conversion and communicating the input and output in C++ std::string and std::wstring objects.

When you create an new web application using visual studio.net, it automatically creates the virtual directory and configures it as an application. However, if you manually create the virtual directory and it is not configured as an application, then you will not be able to browse the application and may get the above error.

You can also install simplejson.

If you have pip (see https://pypi.python.org/pypi/pip) as your Python package manager you can install simplejson with:

 pip install simplejson

This is similar to the comment of installing with easy_install, but I prefer pip to easy_install as you can easily uninstall in pip with "pip uninstall package".

Use

datatable.select("col1='test'","col1 ASC")

Then before binding your data to the grid or repeater etc, use this

datatable.defaultview.sort()

That will solve your problem.

Another option is to use Homebrew which works on Linux and macOS to install just the supporting libraries:

brew install libpq

then

brew link libpq --force

(the --force option is required because it conflicts with the postgres formula.)

Short answer:

As written in xsd:

<xs:attribute name="minOccurs" type="xs:nonNegativeInteger" use="optional" default="1"/>
<xs:attribute name="maxOccurs" type="xs:allNNI" use="optional" default="1"/>

If you provide an attribute with number, then the number is boundary. Otherwise attribute should appear exactly once.

People mentioned string.find(), string.index(), and string.indexOf() in the comments, and I summarize them here (according to the Python Documentation):

First of all there is not a string.indexOf() method. The link posted by Deviljho shows this is a JavaScript function.

Second the string.find() and string.index() actually return the index of a substring. The only difference is how they handle the substring not found situation: string.find() returns -1 while string.index() raises an ValueError.

Besides the session cookie (which is kind of standard), I don't want to use extra cookies.

I found a solution which works for me when building a Single Page Web Application (SPA), with many AJAX requests. Note: I am using server side Java and client side JQuery, but no magic things so I think this principle can be implemented in all popular programming languages.

My solution without extra cookies is simple:

Client Side

Store the CSRF token which is returned by the server after a succesful login in a global variable (if you want to use web storage instead of a global thats fine of course). Instruct JQuery to supply a X-CSRF-TOKEN header in each AJAX call.

The main "index" page contains this JavaScript snippet:

// Intialize global variable CSRF_TOKEN to empty sting. 
// This variable is set after a succesful login
window.CSRF_TOKEN = '';

// the supplied callback to .ajaxSend() is called before an Ajax request is sent
$( document ).ajaxSend( function( event, jqXHR ) {
    jqXHR.setRequestHeader('X-CSRF-TOKEN', window.CSRF_TOKEN);
}); 

Server Side

On successul login, create a random (and long enough) CSRF token, store this in the server side session and return it to the client. Filter certain (sensitive) incoming requests by comparing the X-CSRF-TOKEN header value to the value stored in the session: these should match.

Sensitive AJAX calls (POST form-data and GET JSON-data), and the server side filter catching them, are under a /dataservice/* path. Login requests must not hit the filter, so these are on another path. Requests for HTML, CSS, JS and image resources are also not on the /dataservice/* path, thus not filtered. These contain nothing secret and can do no harm, so this is fine.

@WebFilter(urlPatterns = {"/dataservice/*"})
...
String sessionCSRFToken = req.getSession().getAttribute("CSRFToken") != null ? (String) req.getSession().getAttribute("CSRFToken") : null;
if (sessionCSRFToken == null || req.getHeader("X-CSRF-TOKEN") == null || !req.getHeader("X-CSRF-TOKEN").equals(sessionCSRFToken)) {
    resp.sendError(401);
} else
    chain.doFilter(request, response);
}   

Please everyone note that you can set a cookie from a subdomain on a domain.

(sent in the response for requesting subdomain.mydomain.com)

Set-Cookie: name=value; Domain=mydomain.com // GOOD

But you CAN'T set a cookie from a domain on a subdomain.

(sent in the response for requesting mydomain.com)

Set-Cookie: name=value; Domain=subdomain.mydomain.com // Browser rejects cookie

WHY ?

According to the specifications RFC 6265 section 5.3.6 Storage Model

If the canonicalized request-host does not domain-match the domain-attribute: Ignore the cookie entirely and abort these steps.

and RFC 6265 section 5.1.3 Domain Matching

Domain Matching

A string domain-matches a given domain string if at least one of the following conditions hold:

1. The domain string and the string are identical. (Note that both the domain string and the string will have been canonicalized to lower case at this point.)

2. All of the following conditions hold:

   • The domain string is a suffix of the string.

   • The last character of the string that is not included in the domain string is a %x2E (".") character.

   • The string is a host name (i.e., not an IP address).

So "subdomain.mydomain.com" domain-matches "mydomain.com", but "mydomain.com" does NOT domain-match "subdomain.mydomain.com"

Check this answer also.

directly use

paragraph.add("\n");

to add an empty line.

I think you were pretty close, try this:

@{bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);}
@if (isUserConnected)
{ // meaning that the viewing user has not been saved so continue
    <div>
        <div> click to join us </div>
        <a id="login" href="javascript:void(0);" style="display: inline; ">join here</a>
    </div>
}

If you are working with form validation. Then in this case form send string. I used following code to check either form input is a decimal number or not. I hope this will work for you too.

function is_decimal($input = '') {

    $alphabets = str_split($input);
    $find = array('0','1','2','3','4','5','6','7','8','9','.'); // Please note: All intiger numbers are decimal. If you want to check numbers without point "." then you can remove '.' from array. 

    foreach ($alphabets as $key => $alphabet) {
        if (!in_array($alphabet, $find)) {
            return false;
        }
    }

    // Check if user has enter "." point more then once.
    if (substr_count($input, ".") > 1) {
        return false;
    }

    return true;
}

If Libraries/React.xcodeproj are red in xcode then reinstall node_modules

rm -rf node_modules && yarn

My newly created project from react-native 0.46.3 was red :S I have npm 5.3.0 and yarn 0.24.5 when I did react-native init

A trunk is considered your main code base, a branch offshoot of the trunk. Like, you create a branch if you want to implement a new feature, but don't want to affect the main trunk.

TortoiseSVN has good documentation, and a great diff tool.

I use Visual studio, and I use VisualSVN and TortoiseSVN.

Using Costura.Fody 1.6 & 2.0:
After wasting a bunch of time looking into this same kind of error with all other potential solutions not working, I found that an older version of the DLL I was embedding was in the same directory I was running my newly compiled .exe from. Apparently it looks for a local file in the same directory first, then looks inward to its embedded library. Deleting the old DLL worked.

To be clear, it wasn't that my reference was pointing to an old DLL, it was that a copy of an old DLL was in the directory I was testing my application from on a separate system from that which it was compiled on.

Both Encrypt and Decrypt with AES and DES Algoritham ,This worked for me perfectly GithubLink: Java Code For Encryption and Decryption

package decrypt;

import java.security.Key;
import java.security.NoSuchAlgorithmException;
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.NoSuchPaddingException;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
/* Decrypt encrypted string into plain string with aes and Des algoritham*/ 

public class Decrypt {

public String decrypt(String str,String k) throws Exception {
// Decode base64 to get bytes

 Cipher  dcipher = Cipher.getInstance("AES");
 Key aesKey = new SecretKeySpec(k.getBytes(), "AES");
 dcipher.init(dcipher.DECRYPT_MODE, aesKey);
//System.out.println(aesKey);
byte[] dec = new sun.misc.BASE64Decoder().decodeBuffer(str);
byte[] utf8 = dcipher.doFinal(dec);
//System.out.println(utf8);
// Decode using utf-8
 return new String(utf8, "UTF8");
 }


  public String encrypt(String str,String k) throws Exception {
 Cipher ecipher = Cipher.getInstance("AES");
 Key aeskey = new SecretKeySpec(k.getBytes(),"AES");
 byte[] utf8 = str.getBytes("UTF8");
 ecipher.init(ecipher.ENCRYPT_MODE, aeskey );

 byte[] enc = ecipher.doFinal(utf8);

 return new sun.misc.BASE64Encoder().encode(enc);

}
 public String encrypt(String str,String k,String Algo) throws Exception {
 Cipher ecipher = Cipher.getInstance(Algo);
 Key aeskey = new SecretKeySpec(k.getBytes(),Algo);
 byte[] utf8 = str.getBytes("UTF8");
 ecipher.init(ecipher.ENCRYPT_MODE, aeskey );

    // Decode base64 to get bytes

     Cipher  dcipher = Cipher.getInstance(Algo);
     Key aesKey = new SecretKeySpec(k.getBytes(), Algo);

    Decrypt decrypter = new Decrypt();
     System.out.println("Original String: " + original);

     System.out.println("encrypted String in DES: " + decrypter.encrypt(data1,

This worked for me: Need at least .Net Framework 3.5, Code below displays DataRow turned to Generic.IEnumerable, comboBox1 has been used for a better illustration.

using System.Linq;

DataTable dt = new DataTable();            
dt = myClass.myMethod();                 
List<object> list = (from row in dt.AsEnumerable() select (row["name"])).ToList();
comboBox1.DataSource = list;

Use MM for months. mm is for minutes.

DateTime.Now.ToString("dd/MM/yyyy");

You probably run this code at the begining an hour like (00:00, 05.00, 18.00) and mm gives minutes (00) to your datetime.

From Custom Date and Time Format Strings

"mm" --> The minute, from 00 through 59.

"MM" --> The month, from 01 through 12.

Here is a DEMO. (Which the month part of first line depends on which time do you run this code ;) )

I also faced it and encorrected it like below successfully.

File > Settings > Build, Execution, Deployment > Gradle > Use local gradle distribution

Set the home path as : C:/Program Files/Android/Android Studio/gradle/gradle-version

You may need to upgrade your gradle version.

You could use reduce:

const arr = ["q", "w", "w", "e", "i", "u", "r"]
arr.reduce((acc, cur) => { 
  if(acc[cur]) {
    acc.duplicates.push(cur)
  } else {
    acc[cur] = true //anything could go here
  }
}, { duplicates: [] })

Result would look like this:

{ ...Non Duplicate Values, duplicates: ["w"] }

That way you can do whatever you want with the duplicate values!

public class RemoveDuplicatesFromStingsMethod1UsingLoops {

    public static void main(String[] args) {

        String input = new String("aaabbbcccddd");
        String output = "";
        for (int i = 0; i < input.length(); i++) {
            if (!output.contains(String.valueOf(input.charAt(i)))) {
                output += String.valueOf(input.charAt(i));
            }
        }
        System.out.println(output);
    }
}

output: abcd

In Bootstrap v5 use: data-bs-interval="false"

<div id="carouselExampleCaptions" class="carousel" data-bs-ride="carousel" data-bs-interval="false">

I order to change the dialog buttons and background colors, you will need to extend the Dialog theme, eg.:

<style name="MyDialogStyle" parent="android:Theme.Material.Light.Dialog.NoActionBar">
    <item name="android:buttonBarButtonStyle">@style/MyButtonsStyle</item>
    <item name="android:colorBackground">@color/white</item>
</style>

<style name="MyButtonsStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
    <item name="android:textColor">@color/light.blue</item>
</style>

After that, you need to pass this custom style to the dialog builder, eg. like this:

AlertDialog.Builder(requireContext(), R.style.MyDialogStyle)

If you want to change the color of the text inside the dialog, you can pass a custom view to this Builder:

AlertDialog.Builder.setView(View)

or

AlertDialog.Builder.setView(@LayoutResource int)

Steps to generate Create table DDLs for all the tables in the Hive database and export into text file to run later:

step 1)
create a .sh file with the below content, say hive_table_ddl.sh

#!/bin/bash
rm -f tableNames.txt
rm -f HiveTableDDL.txt
hive -e "use $1; show tables;" > tableNames.txt  
wait
cat tableNames.txt |while read LINE
   do
   hive -e "use $1;show create table $LINE;" >>HiveTableDDL.txt
   echo  -e "\n" >> HiveTableDDL.txt
   done
rm -f tableNames.txt
echo "Table DDL generated"

step 2)

Run the above shell script by passing 'db name' as paramanter

>bash hive_table_dd.sh <<databasename>>

output :

All the create table statements of your DB will be written into the HiveTableDDL.txt

Mine DID execute commands in order. Here's my version of what I was using it for:

START cmd.exe /k "U: & cd U:\Design_stuff\new_lcso_website_2017 & python -m http.server"

I needed to

1. Change to my U drive
2. CD to a specific folder containing a website I'm redesigning
3. Execute python with the http server module (to display the contents in my browser).

If those commands are out of order, it would not display the correct files. I initially forgot to change to U: and, running the batch file on my Desktop, it created a web page in my browser at http://localhost:8000 showing me the contents of my Desktop instead of the folder I wanted.

From Spring Boot application as a Service, I can recommend the Python-based supervisord application. See that stack overflow question for more information. It's really straightforward to set up.
