Fan out was clearly what you wanted. fanout

read rabbitMQ tutorial: https://www.rabbitmq.com/tutorials/tutorial-three-javascript.html

here's my example:

Publisher.js:

amqp.connect('amqp://<user>:<pass>@<host>:<port>', async (error0, connection) => {
    if (error0) {
      throw error0;
    }
    console.log('RabbitMQ connected')
    try {
      // Create exchange for queues
      channel = await connection.createChannel()
      await channel.assertExchange(process.env.EXCHANGE_NAME, 'fanout', { durable: false });
      await channel.publish(process.env.EXCHANGE_NAME, '', Buffer.from('msg'))
    } catch(error) {
      console.error(error)
    }
})

Subscriber.js:

amqp.connect('amqp://<user>:<pass>@<host>:<port>', async (error0, connection) => {
    if (error0) {
      throw error0;
    }
    console.log('RabbitMQ connected')
    try {
      // Create/Bind a consumer queue for an exchange broker
      channel = await connection.createChannel()
      await channel.assertExchange(process.env.EXCHANGE_NAME, 'fanout', { durable: false });
      const queue = await channel.assertQueue('', {exclusive: true})
      channel.bindQueue(queue.queue, process.env.EXCHANGE_NAME, '')

      console.log(" [*] Waiting for messages in %s. To exit press CTRL+C");
      channel.consume('', consumeMessage, {noAck: true});
    } catch(error) {
      console.error(error)
    }
});

here is an example i found in the internet. maybe can also help. https://www.codota.com/code/javascript/functions/amqplib/Channel/assertExchange

Any of the following will remove column foo from the data.table df3:

# Method 1 (and preferred as it takes 0.00s even on a 20GB data.table)
df3[,foo:=NULL]

df3[, c("foo","bar"):=NULL]  # remove two columns

myVar = "foo"
df3[, (myVar):=NULL]   # lookup myVar contents

# Method 2a -- A safe idiom for excluding (possibly multiple)
# columns matching a regex
df3[, grep("^foo$", colnames(df3)):=NULL]

# Method 2b -- An alternative to 2a, also "safe" in the sense described below
df3[, which(grepl("^foo$", colnames(df3))):=NULL]

data.table also supports the following syntax:

## Method 3 (could then assign to df3, 
df3[, !"foo"]  

though if you were actually wanting to remove column "foo" from df3 (as opposed to just printing a view of df3 minus column "foo") you'd really want to use Method 1 instead.

(Do note that if you use a method relying on grep() or grepl(), you need to set pattern="^foo$" rather than "foo", if you don't want columns with names like "fool" and "buffoon" (i.e. those containing foo as a substring) to also be matched and removed.)

Less safe options, fine for interactive use:

The next two idioms will also work -- if df3 contains a column matching "foo" -- but will fail in a probably-unexpected way if it does not. If, for instance, you use any of them to search for the non-existent column "bar", you'll end up with a zero-row data.table.

As a consequence, they are really best suited for interactive use where one might, e.g., want to display a data.table minus any columns with names containing the substring "foo". For programming purposes (or if you are wanting to actually remove the column(s) from df3 rather than from a copy of it), Methods 1, 2a, and 2b are really the best options.

# Method 4:
df3[, .SD, .SDcols = !patterns("^foo$")]

Lastly there are approaches using with=FALSE, though data.table is gradually moving away from using this argument so it's now discouraged where you can avoid it; showing here so you know the option exists in case you really do need it:

# Method 5a (like Method 3)
df3[, !"foo", with=FALSE] 
# Method 5b (like Method 4)
df3[, !grep("^foo$", names(df3)), with=FALSE]
# Method 5b (another like Method 4)
df3[, !grepl("^foo$", names(df3)), with=FALSE]

You can try this nice little trick for C++. Take the expression which gives you the array and then append a comma and the number of elements you want to see. Expanding that value will show you elements 0-(N-1) where N is the number you add after the comma.

For example if pArray is the array, type pArray,10 in the watch window.

In My Case, Im trying to pass messages from Salesforce Marketing Cloud Custom Activity(Domain 1) to Heroku(Domain 2) on load.

The Error Appeared in console, when I loaded my original html page from where message is being passed.

Issue I noticed after reading many blogs is that, the receiver page is not loaded yet. i.e

I need to debug from my receiver page not from sender page.

Simple but glad if it helps anyone.

Can do the following

PRINT dbo.[FunctionName] ( [Parameter/Argument] )

E.g.:

PRINT dbo.StringSplit('77,54')

git commit is nothing but saving our changes officially, for every commit we give commit message, once we are done with commits we can push it to remote to see our change globally

which means we can do numerous commits before we push to remote (we can see the list of commits happened and the messages too) git saves each commit with commit id which is a 40 digit code

and I use git push only when i wanted to see my change in remote (There after i will check whether my code worked in jenkins)

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

It should be located C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log(date stamp)\

1. Look here https://github.com/Rafi993/xgboost/ for building xgboost on your machine. There are many different varieties of the solution above, but it seems that the version in the link above is the good one. At least that worked for me: I've tested it on Windows 7 and Windows Server 2008.

2. Then run the following commands in cmd in order to install python bindings:
   cd python-package python setup.py install

3. You might also need a proper mingw (google for tdm-gcc) and the latest setuptools from anaconda.

I hope it will help

import java.util.Scanner; //import the framework


Scanner input = new Scanner(System.in); //opens a scanner, keyboard
System.out.print("Enter a number: "); //prompt the user
int myInt = input.nextInt(); //store the input from the user

Let me know if you have any questions. Fairly self-explanatory. I commented the code so you can read it. :)

You need to use the URL for the link, such as this:

NSURL *path = [[NSBundle mainBundle] URLForResource:@"imagename" withExtension:@"jpg"];

It will give you a proper URL ref.

With quotes:

cat /etc/*-release | grep "PRETTY_NAME" | sed 's/PRETTY_NAME=//g'

gives output as:

"CentOS Linux 7 (Core)"

Without quotes:

cat /etc/*-release | grep "PRETTY_NAME" | sed 's/PRETTY_NAME=//g' | sed 's/"//g'

gives output as:

CentOS Linux 7 (Core)

Look, Andrew:

"J&J Construction":

SELECT CONCAT('J', CONCAT(CHR(38), 'J Construction')) FROM DUAL;

RyanN suggests

If you want to return False for a NaN and Inf, change line to x = float(s); return (x == x) and (x - 1 != x). This should return True for all floats except Inf and NaN

But this doesn't quite work, because for sufficiently large floats, x-1 == x returns true. For example, 2.0**54 - 1 == 2.0**54

I assume you are meaning "internally" within your application.

you can create your own <a> tag and insert a url in the href like this

<a href="<?php echo site_url('controller/function/uri') ?>">Link</a>

OR you can use the URL helper this way to generate an <a> tag

anchor(uri segments, text, attributes)

So... to use it...

<?php echo anchor('controller/function/uri', 'Link', 'class="link-class"') ?>

and that will generate

<a href="http://domain.com/index.php/controller/function/uri" class="link-class">Link</a>

For the additional commented question

I would use my first example

so...

<a href="<?php echo site_url('controller/function') ?>"><img src="<?php echo base_url() ?>img/path/file.jpg" /></a>

for images (and other assets) I wouldn't put the file path within the php, I would just echo the base_url() and then add the path normally.

In Swift 4, one should use merging(_:uniquingKeysWith:):

Example:

let dictA = ["x" : 1, "y": 2, "z": 3]
let dictB = ["x" : 11, "y": 22, "w": 0]

let resultA = dictA.merging(dictB, uniquingKeysWith: { (first, _) in first })
let resultB = dictA.merging(dictB, uniquingKeysWith: { (_, last) in last })

print(resultA) // ["x": 1, "y": 2, "z": 3, "w": 0]
print(resultB) // ["x": 11, "y": 22, "z": 3, "w": 0]

I had this problem, and on a hunch I removed the Qt Configs from my environment. I.e.,

rm -rf ~/.config/Qt*

Then I started qtcreator and it reconfigured itself with the existing state of the machine. It no longer remembered where my projects were, but that just meant I had to browse to them "for the first time" again.

But more importantly it built itself a coherent set of library paths, so I could rebuild and run my project executables again without the xcb or qxcb libraries going missing.

Try this

git stash save ""

and try pull again

We can also use the readonly only with below attributes -

readonly onclick='return false;'

This is because if we will only use the readonly then radio buttons will be editable. To avoid this situation we can use readonly with above combination. It will restrict the editing and element's values will also passed during form submission.

Optional should mainly be used for results of Services anyway. In the service you know what you have at hand and return Optional.of(someValue) if you have a result and return Optional.empty() if you don't. In this case, someValue should never be null and still, you return an Optional.

While a bit more cryptic than join, you can also multiply the array by a string.

@arr * " "

In practice, the models are used as follows.

In discriminative models, to predict the label y from the training example x, you must evaluate:

which merely chooses what is the most likely class y considering x. It's like we were trying to model the decision boundary between the classes. This behavior is very clear in neural networks, where the computed weights can be seen as a complexly shaped curve isolating the elements of a class in the space.

Now, using Bayes' rule, let's replace the in the equation by . Since you are just interested in the arg max, you can wipe out the denominator, that will be the same for every y. So, you are left with

which is the equation you use in generative models.

While in the first case you had the conditional probability distribution p(y|x), which modeled the boundary between classes, in the second you had the joint probability distribution p(x, y), since p(x | y) p(y) = p(x, y), which explicitly models the actual distribution of each class.

With the joint probability distribution function, given a y, you can calculate ("generate") its respective x. For this reason, they are called "generative" models.

Bad idea, don't do it ever - but here it is how it can be done:

int main()
{
   A aObj;
   int* ptr;

   ptr = (int*)&aObj;

   // MODIFY!
   *ptr = 100;
}

i found Cody Gray 's answer partially helpful, in that it did direct me to the real source of my problem which some of you may also be experiencing: visual studio's test execution stays open by default and maintains a lock on the files.

To stop that predominantly useless behaviour, follow the instructions from https://connect.microsoft.com/VisualStudio/feedback/details/771994/vstest-executionengine-x86-exe-32-bit-not-closing-vs2012-11-0-50727-1-rtmrel

Uncheck Test menu -> Test Settings -> "Keep Test Execution Engine Running"

This exception only happens if you are parsing an empty String/empty byte array.

below is a snippet on how to reproduce it:

String xml = ""; // <-- deliberately an empty string.
ByteArrayInputStream xmlStream = new java.io.ByteArrayInputStream(xml.getBytes());
Unmarshaller u = JAXBContext.newInstance(...)
u.setSchema(...);
u.unmarshal( xmlStream ); // <-- here it will fail

SQL Server recognizes 'TRUE' and 'FALSE' as bit values. So, use a bit data type!

declare @var bit
set @var = 'true'
print @var

That returns 1.

In addition to the above configurations, I had to set deployment target to "Open Select Deployment Target Dialog", run once (choosing my device from the options listed), and from then on Android Studio was able to see my device even after changing the deployment setting back to "USB Device". My SWAG is that since Android Studio uses its own internal cache to find your device, it has to be initialized first.

# Source: Class and Instance Variables
# https://docs.python.org/2/tutorial/classes.html#class-and-instance-variables

class MyClass(object):
    # class variable
    my_CLS_var = 10

    # sets "init'ial" state to objects/instances, use self argument
    def __init__(self):
        # self usage => instance variable (per object)
        self.my_OBJ_var = 15

        # also possible, class name is used => init class variable
        MyClass.my_CLS_var = 20


def run_example_func():
    # PRINTS    10    (class variable)
    print MyClass.my_CLS_var

    # executes __init__ for obj1 instance
    # NOTE: __init__ changes class variable above
    obj1 = MyClass()

    # PRINTS    15    (instance variable)
    print obj1.my_OBJ_var

    # PRINTS    20    (class variable, changed value)
    print MyClass.my_CLS_var


run_example_func()

maybe you can try this way

SELECT * FROM Product P WHERE (CASE WHEN @Status = 'published' THEN (CASE WHEN P.Status IN (1, 3) THEN 'TRUE' ELSE FALSE END) WHEN @Status = 'standby' THEN (CASE WHEN P.Status IN (2, 5, 9, 6) THEN 'TRUE' ELSE 'FALSE' END) WHEN @Status = 'deleted' THEN (CASE WHEN P.Status IN (4, 5, 8, 10) THEN 'TRUE' ELSE 'FALSE' END) ELSE (CASE WHEN P.Status IN (1, 3) THEN 'TRUE' ELSE 'FALSE' END) END) = 'TRUE'

In this way if @Status = 'published', the query will check if P.Status is among 1 or 3, it will return TRUE else 'FALSE'. This will be matched with TRUE at the end

Hope it helps.

This will print each character in text

text = raw_input("Give some input:  ")
for i in range(0,len(text)):
   print(text[i])

As stated in MSDN (eg. https://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog(v=vs.110).aspx ), checking an non existing source and creating a source requires admin privilege.

It is however possible to use the source "Application" without. In my test under Windows 2012 Server r2, I however get the following log entry using "Application" source:

The description for Event ID xxxx from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: {my event entry message} the message resource is present but the message is not found in the string/message table

I defined the following method to create the source:

    private string CreateEventSource(string currentAppName)
    {
        string eventSource = currentAppName;
        bool sourceExists;
        try
        {
            // searching the source throws a security exception ONLY if not exists!
            sourceExists = EventLog.SourceExists(eventSource);
            if (!sourceExists)
            {   // no exception until yet means the user as admin privilege
                EventLog.CreateEventSource(eventSource, "Application");
            }
        }
        catch (SecurityException)
        {
            eventSource = "Application";
        }

        return eventSource;
    }

I am calling it with currentAppName = AppDomain.CurrentDomain.FriendlyName

It might be possible to use the EventLogPermission class instead of this try/catch but not sure we can avoid the catch.

It is also possible to create the source externally, e.g in elevated Powershell:

New-EventLog -LogName Application -Source MyApp

Then, using 'MyApp' in the method above will NOT generate exception and the EventLog can be created with that source.

You can also do this in the Visual Studio debugger without modifying the code.

1. Create a breakpoint where you want to see the stack trace.
2. Right-click the breakpoint and select "Actions..." in VS2015. In VS2010, select "When Hit...", then enable "Print a message".
3. Make sure "Continue execution" is selected.
4. Type in some text you would like to print out.
5. Add $CALLSTACK wherever you want to see the stack trace.
6. Run the program in the debugger.

Of course, this doesn't help if you're running the code on a different machine, but it can be quite handy to be able to spit out a stack trace automatically without affecting release code or without even needing to restart the program.

git checkout origin/[branch] .
git status

// Note dot (.) at the end. And all will be good

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

Try

SELECT li.clientid, group_concat(li.views ORDER BY li.views) AS views,
       group_concat(li.percentage ORDER BY li.percentage) 
FROM table_views li 
GROUP BY client_id

http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function%5Fgroup-concat

Query syntax

var query = from p in context.People
            group p by p.name into g
            select new
            {
              name = g.Key,
              count = g.Count()
            };

Method syntax

var query = context.People
                   .GroupBy(p => p.name)
                   .Select(g => new { name = g.Key, count = g.Count() });

A single way to remove sessions is setting it to null;

Session["your_session"] = null;

If you find yourself writing the above solution as often as I do then you could implement it as a generic:

public static int GetEnumEntries<T>() where T : struct, IConvertible 
{
    if (!typeof(T).IsEnum)
        throw new ArgumentException("T must be an enumerated type");

    return Enum.GetNames(typeof(T)).Length;
}

Here's example with simple object exporting.

var MyScreen = {

    /* ... */

    width : function (percent){

        return window.innerWidth / 100 * percent

    }

    height : function (percent){

        return window.innerHeight / 100 * percent

    }


};

export default MyScreen

In main file (Use when you don't want and don't need to create new instance) and it is not global you will import this only when it needed :

import MyScreen from "./module/screen";
console.log( MyScreen.width(100) );

dir=/home/smith/Desktop/Test
parentdir="$(dirname "$dir")"

Works if there is a trailing slash, too.

Simply apply aggregation function, Sum on your column

df.groupby('steps').sum().show()

There are several ways to do this, below are two options:

Option 1 - Right click on the database you want to copy

• Choose 'Tasks' > 'Generate scripts'

• 'Select specific database objects'

• Check 'Tables'

• Mark 'Save to new query window'

• Click 'Advanced'

• Set 'Types of data to script' to 'Schema and data'

• Next, Next

You can now run the generated query on the new database.

Option 2

• Right click on the database you want to copy

• 'Tasks' > 'Export Data'

• Next, Next

• Choose the database to copy the tables to

• Mark 'Copy data from one or more tables or views'

• Choose the tables you want to copy

• Finish

Here is a nice explanation of update operation with some examples. Although it is Postgres site, but the SQL queries are valid for the other DBs, too. The following examples are intuitive to understand.

-- Update contact names in an accounts table to match the currently assigned salesmen:

UPDATE accounts SET (contact_first_name, contact_last_name) =
    (SELECT first_name, last_name FROM salesmen
     WHERE salesmen.id = accounts.sales_id);

-- A similar result could be accomplished with a join:

UPDATE accounts SET contact_first_name = first_name,
                    contact_last_name = last_name
  FROM salesmen WHERE salesmen.id = accounts.sales_id;

However, the second query may give unexpected results if salesmen.id is not a unique key, whereas the first query is guaranteed to raise an error if there are multiple id matches. Also, if there is no match for a particular accounts.sales_id entry, the first query will set the corresponding name fields to NULL, whereas the second query will not update that row at all.

Hence for the given example, the most reliable query is like the following.

UPDATE tempDataView SET (marks) =
    (SELECT marks FROM tempData
     WHERE tempDataView.Name = tempData.Name);

I have created the following class and used across the application wherever required in place of GridView:

/// <summary>
/// Represents a view mode that displays data items in columns for a System.Windows.Controls.ListView control with auto sized columns based on the column content     
/// </summary>
public class AutoSizedGridView : GridView
{        
    protected override void PrepareItem(ListViewItem item)
    {
        foreach (GridViewColumn column in Columns)
        {
            // Setting NaN for the column width automatically determines the required
            // width enough to hold the content completely.

            // If the width is NaN, first set it to ActualWidth temporarily.
            if (double.IsNaN(column.Width))
              column.Width = column.ActualWidth;

            // Finally, set the column with to NaN. This raises the property change
            // event and re computes the width.
            column.Width = double.NaN;              
        }            
        base.PrepareItem(item);
    }
}

I would've done it slightly different

 <input type="radio" value="1" name="userradiobtn" id="userradiobtn" />   
 <input type="radio" value="2" name="userradiobtn" id="userradiobtn" />    
 <input type="radio" value="3" name="userradiobtn" id="userradiobtn" class="disablebox"/>   
 <input type="checkbox" value="4" name="chkbox" id="chkbox" class="showbox"/>    
 <input type="text" name="usertxtbox" id="usertxtbox" class="showbox" />   

Notice class attribute

 $(document).ready(function() {      
    $('.disablebox').click(function() {
        $('.showbox').attr("disabled", true);           
    });
});

This way should you need to add more radio buttons you don't need to worry about changing the javascript

While reading this thread, I often get the impression that people are using "UTF-8" as a synonym to "Unicode". Please make a distinction between Unicode's "Code-Points" which are an enlarged relative of the ASCII code and Unicode's various "encodings". And there are a few of them, of which UTF-8, UTF-16 and UTF-32 are the current ones and a few more are obsolete.

Please, UTF-8 (as well as all other encodings) exists and have meaning in input or in output only. Internally, since Perl 5.8.1, all strings are kept as Unicode "Code-points". True, you have to enable some features as admiringly covered previously.

Probably not the most performance friendly way, but you could create a scalar function that pulls from the information schema with the table and column name, and then call that using the isnull logic you tried earlier:

    CREATE FUNCTION GetDefaultValue
    (
        @TableName VARCHAR(200),
        @ColumnName VARCHAR(200)
    )
    RETURNS VARCHAR(200)
    AS
    BEGIN
        -- you'd probably want to have different functions for different data types if
        -- you go this route
    RETURN (SELECT TOP 1 REPLACE(REPLACE(REPLACE(COLUMN_DEFAULT, '(', ''), ')', ''), '''', '') 
            FROM information_schema.columns
            WHERE table_name = @TableName AND column_name = @ColumnName)

    END
    GO

And then call it like this:

INSERT INTO t (value) VALUES ( ISNULL(@value, SELECT dbo.GetDefaultValue('t', 'value') )

It's very simple just use a function on javaScript and call it onclick

   <script type="text/javascript">
            function change()
            {
            document.getElementById("catestory").style.backgroundColor="#666666";
            }
            </script>

    <a href="#" onclick="change()">Change Bacckground Color</a>

// open in default browser
Process.Start("http://www.stackoverflow.net");

ul li{
  display: inline;
}

For more see the basic list options and a basic horizontal list at listamatic. (thanks to Daniel Straight below for the links).

Also, as pointed out in the comments, you probably want styling on the ul and whatever elements go inside the li's and the li's themselves to get things to look nice.

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

Use this in web.config:

<sessionState 

  timeout="20" 
/>

Os X Mojave 10.14 has:

Error: The Command Line Tools header package must be installed on Mojave.

Solution. Go to

/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

location and install the package manually. And brew will start working and we can run:

brew uninstall --force git
brew cleanup --force -s git
brew prune
brew install git

user double quote to get the exact value. like this:

echo "${var}"

and it will read your value correctly.

How to dynamically alter the minDate (after init)

The above answers address how to set the default minDate at init, but the question was actually how to dynamically alter the minDate, below I also clarify How to set the default minDate.

All that was wrong with the original question was that the minDate value being set should have been a string (don't forget the quotes):

$('#datePickerId').datepicker('option', 'minDate', '3');

minDate also accepts a date object and a common use is to have an end date you are trying to calculate so something like this could be useful:

$('#datePickerId').datepicker(
    'option', 'minDate', new Date($(".datePop.start").val())
);

How to set the default minDate (at init)

Just answering this for best practice; the minDate option expects one of:

1. a string in the current dateFormat OR
2. number of days from today (e.g. +7) OR
3. string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '-1y -1m')

@bogart setting the string to "0" is a solution as it satisfies option 2 above

$('#datePickerId').datepicker('minDate': '3');

jQuery UI docs for minDate

try this.

filename = Path.ChangeExtension(".blah") 

in you Case:

myfile= c:/my documents/my images/cars/a.jpg;
string extension = Path.GetExtension(myffile);
filename = Path.ChangeExtension(myfile,".blah") 

You should look this post too:

If it is not working I recomand to read this resources below :

You probably want to check the length of the string first and do something like this:

if (!myStr.empty())
{
    char lastChar = *myStr.rbegin();
}

<input type="image" name="your_image_name" src="your_image_url.png" />

This will send the your_image_name.x and your_image_name.y values as it submits the form, which are the x and y coordinates of the position the user clicked the image.

You can call a JavaScript function and use window.location = 'url';:

http://www.pageresource.com/jscript/jredir.htm

An alternative for the bind() method.

Use the click() method, do something like this:

commentbtn.click({id: 10, name: "João"}, onClickCommentBtn);

function onClickCommentBtn(event)
{
  alert("Id=" + event.data.id + ", Name = " + event.data.name);
}

Or, if you prefer:

commentbtn.click({id: 10, name: "João"},  function (event) {
  alert("Id=" + event.data.id + ", Nome = " + event.data.name);
});

It will show an alert box with the following infos:

Id = 10, Name = João

ruby on rails notes has a very nice blogpost about commenting in erb-files

the short version is

to comment a single line use

<%# commented line %>

to comment a whole block use a if false to surrond your code like this

<% if false %>
code to comment
<% end %>

None of the other answers will preseve any querystring values. Try

<a href="javascript:window.location.href=window.location.href">

Admittedly this does involve javascript but, unless your users have script disabled, this is pretty straightforward.

This is a very common misconception. There is no live HTML5 video support (except for HLS on iOS and Mac Safari). You may be able to 'hack' it using a webm container, but I would not expect that to be universally supported. What you are looking for is included in the Media Source Extensions, where you can feed the fragments to the browser one at a time. but you will need to write some client side javascript.

Try with this:

cv::bilateralFilter(img, 9, 75, 75);

We can use title() function with negative line value to bring down the title.

See this example:

plot(1, 1)
title("Title", line = -2)

It's not smart to have python code inside java. Wrap your python code with flask or other web framework to make it as a microservice. Make your java program able to call this microservice (e.g. via REST).

Beleive me, this is much simple and will save you tons of issues. And the codes are loosely coupled so they are scalable.

Updated on Mar 24th 2020: According to @stx's comment, the above approach is not suitable for massive data transfer between client and server. Here is another approach I recommended: Connecting Python and Java with Rust(C/C++ also ok). https://medium.com/@shmulikamar/https-medium-com-shmulikamar-connecting-python-and-java-with-rust-11c256a1dfb0

Alright, so let's first start with making the distinction between Javascript in a web browser, and Javascript on a server (CommonJS and Node).

Javascript is a language traditionally confined to a web browser with a limited global context defined mostly by what came to be known as the Document Object Model (DOM) level 0 (the Netscape Navigator Javascript API).

Server-side Javascript eliminates that restriction and allows Javascript to call into various pieces of native code (like the Postgres library) and open sockets.

Now require() is a special function call defined as part of the CommonJS spec. In node, it resolves libraries and modules in the Node search path, now usually defined as node_modules in the same directory (or the directory of the invoked javascript file) or the system-wide search path.

To try to answer the rest of your question, we need to use a proxy between the code running in the the browser and the database server.

Since we are discussing Node and you are already familiar with how to run a query from there, it would make sense to use Node as that proxy.

As a simple example, we're going to make a URL that returns a few facts about a Beatle, given a name, as JSON.

/* your connection code */

var express = require('express');
var app = express.createServer();
app.get('/beatles/:name', function(req, res) {
    var name = req.params.name || '';
    name = name.replace(/[^a-zA_Z]/, '');
    if (!name.length) {
        res.send({});
    } else {
        var query = client.query('SELECT * FROM BEATLES WHERE name =\''+name+'\' LIMIT 1');
        var data = {};
        query.on('row', function(row) {
            data = row;
            res.send(data);
        });
    };
});
app.listen(80, '127.0.0.1');

I haven't used Cassandra, but I have used MongoDB and think it's awesome.

If you're after simple setup, this is it: You simply untar MongoDB and run the mongod daemon and that's it ... it's running.

Obviously that's only a starter, but to get you started it's easy.

I found this topic while searching for run script for startup and shutdown Windows 10. Those answers above didn't working. For me on windows 10 worked when I put scripts to task scheduler. How to do this: press window key and write Task scheduler, open it, then on the right is Add task... button. Here you can add scripts. PS: I found action for startup and logout user, there is not for shutdown.

 <style name="AppThemeLight" parent="Theme.AppCompat.Light.NoActionBar">

this works fine for me

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

Surround your %1 with something.

Eg:

if not "%1" == ""

Another one I've seen fairly often:

if not {%1} == {}

And so on...

The problem, as you can likely guess, is that the %1 is literally replaced with emptiness. It is not 'an empty string' it is actually a blank spot in your source file at that point.

Then after the replacement, the interpreter tries to parse the if statement and gets confused.

At least for pip 1.3.1, it honors the http_proxy and https_proxy environment variables. Make sure you define both, as it will access the PYPI index using https.

export https_proxy="http://<proxy.server>:<port>"
pip install TwitterApi

I am using a ListView instead of a GridView in 3.5. When the user wants to edit I have set the selected item of the dropdown to the exising value of that column for the record. I am able to access the dropdown in the ItemDataBound event. Here's the code:

protected void listViewABC_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    // This stmt is used to execute the code only in case of edit 
    if (((ListView)(sender)).EditIndex != -1 && ((ListViewDataItem)(e.Item)).DisplayIndex == ((ListView)(sender)).EditIndex)
    {
        ((DropDownList)(e.Item.FindControl("ddlXType"))).SelectedValue = ((MyClass)((ListViewDataItem)e.Item).DataItem).XTypeId.ToString();
        ((DropDownList)(e.Item.FindControl("ddlIType"))).SelectedValue = ((MyClass)((ListViewDataItem)e.Item).DataItem).ITypeId.ToString();
    }
}

This problem also arise when we don't give the single or double quotes to the database value.

Wrong way:

$query ="INSERT INTO tabel_name VALUE ($value1,$value2)";

As database inserting values must be in quotes ' '/" "

Right way:

$query ="INSERT INTO STUDENT VALUE ('$roll_no','$name','$class')";

x ~= 0 or 1 is the same as ((x ~= 0) or 1)

x ~=(0 or 1) is the same as (x ~= 0).

try something like this instead.

function isNot0Or1(x)
    return (x ~= 0 and x ~= 1)
end

print( isNot0Or1(-1) == true )
print( isNot0Or1(0) == false )
print( isNot0Or1(1) == false )

Download the JDK version of the JRE to the installed JRE's and use that instead.
In Eclipse Indigo, if you check the classpath tab on the run configuration for ant, you will see that it defaults to adding the tools.jar from the system. So if you launch Eclipse using Java7 and run an ant build using a separate JRE6 it generates an UnsupportedClassVersionError. When I added the JDK version Eclipse picked up the tools.jar from the JDK and my ant task ran successfully.

This is an old question, but no one seems to have mentioned this.

You were getting lucky that the thing was linking at all.

You needed to change

g++ -g -Wall -o my_binary -L/my/dir -lfoo bar.cpp

to this:

g++ -g -Wall -o my_binary -L/my/dir bar.cpp -lfoo

Your linker keeps track of symbols it needs to resolve. If it reads the library first, it doesn't have any needed symbols, so it ignores the symbols in it. Specify the libraries after the things that need to link to them so that your linker has symbols to find in them.

Also, -lfoo makes it search specifically for a file named libfoo.a or libfoo.so as needed. Not libfoo.so.0. So either ln the name or rename the library as appopriate.

To quote the gcc man page:

-l library
   ...
   It makes a difference where in the command you 
   write this option; the linker searches and processes 
   libraries and object files in the order they are 
   specified.  Thus, foo.o -lz bar.o searches library z 
   after file foo.o but before bar.o.  If bar.o refers 
   to functions in z, those functions may not be loaded.

Adding the file directly to g++'s command line should have worked, unless of course, you put it prior to bar.cpp, causing the linker to ignore it for lacking any needed symbols, because no symbols were needed yet.

Git GUI has a PUSH button - pardon the pun, and the dialog box it opens has a checkbox for tags.

I pushed a branch from the command line, without tags, and then tried again pushing the branch using the --follow-tags option descibed above. The option is described as following annotated tags. My tags were simple tags.

I'd fixed something, tagged the commit with the fix in, (so colleagues can cherry pick the fix,) then changed the software version number and tagged the release I created (so colleagues can clone that release).

Git returned saying everything was up-to-date. It did not send the tags! Perhaps because the tags weren't annotated. Perhaps because there was nothing new on the branch.

When I did a similar push with Git GUI, the tags were sent.

For the time being, I am going to be pushing my changes to my remotes with Git GUI and not with the command line and --follow-tags.

For me, running $(boot2docker shellinit 2> /dev/null) fixed the problem.

This runs the output of the boot2docker shellinit command (the three set -x ... lines) in your current terminal session, which lets the docker command know where to find the boot2docker virtual machine.

Adding $(boot2docker shellinit 2> /dev/null) to the bottom of your ~/.bash_profile file will make sure the docker command is configured, every time you open your terminal.

For people using Fish shell: boot2docker shellinit ^ /dev/null | source.

Note that 2> /dev/null (and the Fish equivalent ^ /dev/null) are optional. Like @pablo-fernandez suggested, this hides the Writing .. lines.

Can't believe this thread was going on for so long. You would get this error if you got distracted and used [] instead of (), at least my case.

Pop is a method on the list data type, https://docs.python.org/2/tutorial/datastructures.html#more-on-lists

Therefore, you shouldn't be using pop as if it was a list itself, pop[0]. It's a method that takes an optional parameter representing an index, so as Tushar Palawat pointed out in one of the answers that didn't get approved, the correct adjustment which will fix the example above is:

listb.pop(0)

If you don't believe, run a sample such as:

if __name__ == '__main__':
  listb = ["-test"]
  if( listb[0] == "-test"):
    print(listb.pop(0))

Other adjustments would work as well, but it feels as they are abusing the Python language. This thread needs to get fixed, not to confuse users.

Addition, a.pop() removes and returns the last item in the list. As a result, a.pop()[0] will get the first character of that last element. It doesn't seem that is what the given code snippet is aiming to achieve.

No.

Either use verbatim string literals as you have, or escape the " using backslash.

string test = "He said to me, \"Hello World\" . How are you?";

The string has not changed in either case - there is a single escaped " in it. This is just a way to tell C# that the character is part of the string and not a string terminator.

You can just put this for example at the top of the file:

/* eslint-disable no-console */

vb.net version

Me.Background = CType(New BrushConverter().ConvertFrom("#ffaacc"), SolidColorBrush)

this should work:

public void setSections (Context c,  List<Section> sectionList){
    this.sectionList = sectionList;

    Type sectionListType = new TypeToken<ArrayList<Section>>(){}.getType();
    String sectionListString = new Gson().toJson(sectionList,sectionListType);

    SharedPreferences.Editor editor = getSharedPreferences(c).edit().putString(PREFS_KEY_SECTIONS, sectionListString);
    editor.apply();
}

them, to catch it just:

public List<Section> getSections(Context c){

    if(this.sectionList == null){
        String sSections = getSharedPreferences(c).getString(PREFS_KEY_SECTIONS, null);

        if(sSections == null){
            return new ArrayList<>();
        }

        Type sectionListType = new TypeToken<ArrayList<Section>>(){}.getType();
        try {

            this.sectionList = new Gson().fromJson(sSections, sectionListType);

            if(this.sectionList == null){
                return new ArrayList<>();
            }
        }catch (JsonSyntaxException ex){

            return new ArrayList<>();

        }catch (JsonParseException exc){

            return new ArrayList<>();
        }
    }
    return this.sectionList;
}

it works for me.

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then

Angular2 v2.1.0 (stable):

The ActivatedRoute provides an observable one can subscribe.

  constructor(
     private route: ActivatedRoute
  ) { }

  this.route.params.subscribe(params => {
     let value = params[key];
  });

This triggers everytime the route gets updated, as well: /home/files/123 -> /home/files/321

1. To convert and append an integer, use operator += (or member function concat):

   String stringOne = "A long integer: ";
   stringOne += 123456789;
   

2. To get the string as type char[], use toCharArray():

   char charBuf[50];
   stringOne.toCharArray(charBuf, 50)
   

In the example, there is only space for 49 characters (presuming it is terminated by null). You may want to make the size dynamic.

Overhead

The cost of bringing in String (it is not included if not used anywhere in the sketch), is approximately 1212 bytes program memory (flash) and 48 bytes RAM.

This was measured using Arduino IDE version 1.8.10 (2019-09-13) for an Arduino Leonardo sketch.

For SwiftUI, try

TextField ("Email", text: $email)
    .textFieldStyle(RoundedBorderTextFieldStyle()).padding()
SecureField ("Password", text: $password)
    .textFieldStyle(RoundedBorderTextFieldStyle()).padding()

If you don't care about formatting and you just need some quick date, you can use this:

import time
print(time.ctime())

Starting and Stopping MongoDB is covered in the MongoDB manual. It explains the various options of stopping MongoDB through the shell, cli, drivers etc. It also details the risks of incorrectly stopping MongoDB (such as data corruption) and talks about the different kill signals.

Additionally, if you have installed MongoDB using a package manager for Ubuntu or Debian then you can stop mongodb (currently mongod in ubuntu) as follows:

• Upstart: sudo service mongod stop

• Sysvinit: sudo /etc/init.d/mongod stop

Or on Mac OS X

• Find PID of mongod process using $ top

• Kill the process by $ kill <PID> (the Mongo docs have more info on this)

Or on Red Hat based systems:

• service mongod stop

Or on Windows if you have installed as a service named MongoDB:

• net stop MongoDB

And if not installed as a service (as of Windows 7+) you can run:

• taskkill /f /im mongod.exe

MockMultipartFile exists for this purpose. As in your snippet if the file path is known, the below code works for me.

import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import org.springframework.mock.web.MockMultipartFile;

Path path = Paths.get("/path/to/the/file.txt");
String name = "file.txt";
String originalFileName = "file.txt";
String contentType = "text/plain";
byte[] content = null;
try {
    content = Files.readAllBytes(path);
} catch (final IOException e) {
}
MultipartFile result = new MockMultipartFile(name,
                     originalFileName, contentType, content);

Select SQL Management Studio from the dropdown in Download SQL Server 2012 Express.

When you talk about presentation, service, data, network layer, you are talking about layers. When you "deploy them separately", you talk about tiers.

Tiers is all about deployment. Take it this way: We have an application which has a frontend created in Angular, it has a backend as MongoDB and a middle layer which interacts between the frontend and the backend. So, when this frontend application, database application, and the middle layer is all deployed separately, we say it's a 3 tier application.

Benefit: If we need to scale our backend in the future, we only need to scale the backend independently and there's no need to scale up the frontend.

Yesterday, I started to write my own way to bind data.

It's very funny to play with it.

I think it's beautiful and very useful. At least on my tests using firefox and chrome, Edge must works too. Not sure about others, but if they support Proxy, I think it will work.

https://jsfiddle.net/2ozoovne/1/

<H1>Bind Context 1</H1>
<input id='a' data-bind='data.test' placeholder='Button Text' />
<input id='b' data-bind='data.test' placeholder='Button Text' />
<input type=button id='c' data-bind='data.test' />
<H1>Bind Context 2</H1>
<input id='d' data-bind='data.otherTest' placeholder='input bind' />
<input id='e' data-bind='data.otherTest' placeholder='input bind' />
<input id='f' data-bind='data.test' placeholder='button 2 text - same var name, other context' />
<input type=button id='g' data-bind='data.test' value='click here!' />
<H1>No bind data</H1>
<input id='h' placeholder='not bound' />
<input id='i' placeholder='not bound'/>
<input type=button id='j' />

Here is the code:

                            if ( bindKeys[i].startsWith(bindPath+"."+name) ) {
                                // console.log("its ok, lets update dom...", bindKeys[i]);
                                SmartBind.processBindToDom( bindContext, bindKeys[i] );
                            }
                        }
                    }
                    return true;
                }
            };
        }
        SmartBind.processBindToDom=function(bindContext, bindPath) {
            var domList=bindContext.mapDom[bindPath];
            if ( typeof domList != 'undefined' ) {
                try {
                    for ( var i=0; i < domList.length ; i++){
                        var dataTarget=SmartBind.getDataTarget(bindContext, bindPath);
                        if ( 'target' in dataTarget )
                            domList[i].value=dataTarget.target[dataTarget.item];
                        else
                            console.warn("Could not get data target", bindContext, bindPath);
                    }
                } catch (e){
                    console.warn("bind fail", bindPath, bindContext, e);
                }
            }
        }
    }
})();

Then, to set, just:

var bindContext=SmartBind.BindContext();
SmartBind.add(bindContext, document.getElementById('a'));
SmartBind.add(bindContext, document.getElementById('b'));
SmartBind.add(bindContext, document.getElementById('c'));

var bindContext2=SmartBind.BindContext();
SmartBind.add(bindContext2, document.getElementById('d'));
SmartBind.add(bindContext2, document.getElementById('e'));
SmartBind.add(bindContext2, document.getElementById('f'));
SmartBind.add(bindContext2, document.getElementById('g'));

setTimeout( function() {
    document.getElementById('b').value='Via Script works too!'
}, 2000);

document.getElementById('g').addEventListener('click',function(){
bindContext2.data.test='Set by js value'
})

For now, I've just added the HTMLInputElement value bind.

Let me know if you know how to improve it.

This is the sort of thing that sed is really good at: $ sed 's/[ \t]*$//'. Be aware the you will probably need to literally type a TAB character instead of \t for this to work.

Here is some code:

private void dgvStandingOrder_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (dgvStandingOrder.Columns[e.ColumnIndex].Name == "IsSelected" && dgvStandingOrder.CurrentCell is DataGridViewCheckBoxCell)
    {
        bool isChecked = (bool)dgvStandingOrder[e.ColumnIndex, e.RowIndex].EditedFormattedValue;
        if (isChecked == false)
        {
            dgvStandingOrder.Rows[e.RowIndex].Cells["Status"].Value = "";
        }
        dgvStandingOrder.EndEdit();
    }
}

private void dgvStandingOrder_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{

    dgvStandingOrder.CommitEdit(DataGridViewDataErrorContexts.Commit);
}

private void dgvStandingOrder_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
    if (dgvStandingOrder.CurrentCell is DataGridViewCheckBoxCell)
    {
        dgvStandingOrder.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}

After experiencing issues with sites breaking on Edge when using High Contrast Mode, I came across the following work by Jeff Clayton:

https://browserstrangeness.github.io/css_hacks.html

It's a crazy, weird media query, but those are easier to use in Sass:

@media screen and (min-width:0\0) and (min-resolution:+72dpi), \0screen\,screen\9 {
   .selector { rule: value };
}

This targets IE versions expect for IE8.

Or you can use:

@media screen\0 {
  .selector { rule: value };
}

Which targets IE8-11, but also triggers FireFox 1.x (which for my use case, doesn't matter).

Right now I'm testing with print support, and this seems to be working okay:

@media all\0 {
  .selector { rule: value };
}

Load url helper in controller

$this->load->helper('url');

A good rule of thumb: use the built-in help system in Python. Example below...

The quote PASV command is not a command to the ftp.exe program, it is a command to the FTP server requesting a high order port for data transfer. A passive transfer is one in which the FTP data over these high order ports while control is maintained in the lower ports.

The windows ftp.exe program can be used to send the FTP server commands to make a passive data transfer between two FTP servers. A standard windows installation will not, and probably should not, have FTP server service running as an endpoint for passive transfers. So if passive transfers are needed with a standard windows box, a solution other than ftp.exe is necessary as FTPing to localhost as one of the connections won't work in most windows environments.

You can effect a passive FTP transfer between two different hosts (but not two connections on the same host) as follows:

Open up two prompts, use one to ftp.exe connect to your source FTP server and one to ftp.exe connect to your destination FTP server.

Now establish a passive connection between the servers using the raw commands PASV and PORT. The quote PASV command will respond with an IP/port in ellipsis. Use that data for the quote PORT <data> command. Your passive link is now established assuming that firewalls haven't blocked one or more of the four ports (2 for FTP control, 2 for FTP data)

Next start receive of data with the quote STOR <filename> command to the receiving FTP server then send the control command quote RETR <filename> to the source FTP server.

so for me:

client 1
> ftp.exe server1
ftp> quote PASV
227 Entering Passive Mode (10,0,3,1,54,161)

client 2 
> ftp.exe server2
ftp> quote PORT 10,0,3,1,54,54,161
ftp> quote STOR myFile

client 1
ftp> quote RETR myFile

Cavet: I'm connecting to some old FTP servers YMMV

I was getting the same error messages. It was a silly mistake on my end, I was not running ng serve in the directory where my Angular project is. Make sure you are in the correct directory (project directory) before running this command.

You want in page A to know the URL of page B?

Or to know in page B the URL of page A?

In Page B: document.referrer if set. As already shown here: How to get the previous URL in JavaScript?

In page A you would need to read a cookie or local/sessionStorage you set in page B, assuming the same domains

You should add "throws IOException" to your main method:

public static void main(String[] args) throws IOException {

You can read a bit more about checked exceptions (which are specific to Java) in JLS.

<select v-model="challan.warehouse_id">
<option value="">Select Warehouse</option>
<option v-for="warehouse in warehouses" v-bind:value="warehouse.id"  >
   {{ warehouse.name }}
</option>

Here "challan.warehouse_id" come from "challan" object you get from:

editChallan: function() {
    let that = this;
    axios.post('/api/challan_list/get_challan_data', {
    challan_id: that.challan_id
 })
 .then(function (response) {
    that.challan = response.data;
 })
 .catch(function (error) {
    that.errors = error;
  }); 
 }

Using your radio button's ID, try rb.SelectedValue.

You can do this with php if the button opens a new page.

For example if the button link to a page named pagename.php as, url: www.website.com/pagename.php the button will stay red as long as you stay on that page.

I exploded the url by '/' an got something like:

url[0] = pagename.php

<? $url = explode('/', substr($_SERVER['REQUEST_URI'], strpos('/',$_SERVER['REQUEST_URI'] )+1,strlen($_SERVER['REQUEST_URI']))); ?>


<html>
<head>
  <style>
    .btn{
     background:white;
     }
    .btn:hover,
    .btn-on{
     background:red;
     }
  </style>
</head>
<body>
   <a href="/pagename.php" class="btn <? if (url[0]='pagename.php') {echo 'btn-on';} ?>">Click Me</a>
</body>
</html>

note: I didn't try this code. It might need adjustments.

I don't actually get an error with this.

a <- as.data.frame(matrix(c(sample(letters,50, replace=T),runif(100)), nrow=50))
b <- sample(letters,10, replace=T)
c <- cbind(a,b)

I used letters incase joining all numerics had different functionality (which it didn't). Your 'first data frame', which is actually just a vector', is just repeated 5 times in that 4th column...

But all the comments from the gurus to the question are still relevant :)

To remove the commas, you'll need to use replace on the string. To convert to a float so you can do the maths, you'll need parseFloat:

var total = parseFloat('100,000.00'.replace(/,/g, '')) +
            parseFloat('500,000.00'.replace(/,/g, ''));

Another way to do it:

>>> set(['a','b']).issubset( ['b','a','foo','bar'] )
True

Your fns is a cellstr array. You need to index in to it with {} instead of () to get the single string out as char.

fns{i}
teststruct.(fns{i})

Indexing in to it with () returns a 1-long cellstr array, which isn't the same format as the char array that the ".(name)" dynamic field reference wants. The formatting, especially in the display output, can be confusing. To see the difference, try this.

name_as_char = 'a'
name_as_cellstr = {'a'}

Use nc command,

nc -zv <hostname/ip> <port/port range>

For example,
nc -zv localhost 27017-27019
or
nc -zv localhost 27017

You can also use telnet command

telnet <ip/host> port

I had a similar issue last night and the problem, was related to the fact that I had dragged a class from the Finder to my project in Xcode.

The solution was to go the the Build Phases tab and then the Compile Sources and make sure you drag the class to the list.

Apache/HTTPD tends to be around in most enterprises or if you're using Centos/etc at home. So, if you have that around, you can do a proxy very easily to add the necessary CORS headers.

I have a blog post on this here as I suffered with it quite a few times recently. But the important bit is just adding this to your /etc/httpd/conf/httpd.conf file and ensuring you are already doing "Listen 80":

<VirtualHost *:80>
    <LocationMatch "/SomePath">
       ProxyPass http://target-ip:8080/SomePath
       Header add "Access-Control-Allow-Origin" "*"
    </LocationMatch>
</VirtualHost>

This ensures that all requests to URLs under your-server-ip:80/SomePath route to http://target-ip:8080/SomePath (the API without CORS support) and that they return with the correct Access-Control-Allow-Origin header to allow them to work with your web-app.

Of course you can change the ports and target the whole server rather than SomePath if you like.

You are specifying .fixedbutton in your CSS (a class) and specifying the id on the element itself.

Change your CSS to the following, which will select the id fixedbutton

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
}

Here's a jsFiddle courtesy of JoshC.

Looking at the documentation for JSON, it seems that the regex can simply be three parts if the goal is just to check for fitness:

1. The string starts and ends with either [] or {}
   • [{\[]{1}...[}\]]{1}
2. and
   1. The character is an allowed JSON control character (just one)
      • ...[,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]...
   2. or The set of characters contained in a ""
      • ...".*?"...

All together: [{\[]{1}([,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]|".*?")+[}\]]{1}

If the JSON string contains newline characters, then you should use the singleline switch on your regex flavor so that . matches newline. Please note that this will not fail on all bad JSON, but it will fail if the basic JSON structure is invalid, which is a straight-forward way to do a basic sanity validation before passing it to a parser.

Here a complete example :

Suppose we have a Person class like :

public class Person
{
    protected String fname;
    protected String lname;

    public Person()
    {

    }

    public Person(String fname, String lname)
    {
        this.fname = fname;
        this.lname = lname;
    }

    public boolean equals(Object objet)
    {
        if(objet instanceof Person)
        {
            Person p = (Person) objet;
            return (p.getFname().equals(this.fname)) && p.getLname().equals(this.lname));
        }
        else return super.equals(objet);
    }

    @Override
    public String toString()
    {
        return "Person(fname : " + getFname + ", lname : " + getLname + ")";
    }

    /** Getters and Setters **/
}

Now we create a comparator :

import java.util.Comparator;

public class ComparePerson implements Comparator<Person>
{
    @Override
    public int compare(Person p1, Person p2)
    {
        if(p1.getFname().equalsIgnoreCase(p2.getFname()))
        {
            return p1.getLname().compareTo(p2.getLname());
        }
        return p1.getFname().compareTo(p2.getFname());
    }
}

Finally suppose we have a group of persons :

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class Group
{
    protected List<Person> listPersons;

    public Group()
    {
        this.listPersons = new ArrayList<Person>();
    }

    public Group(List<Person> listPersons)
    {
        this.listPersons = listPersons;
    }

    public void order(boolean asc)
    {
        Comparator<Person> comp = asc ? new ComparePerson() : Collections.reverseOrder(new ComparePerson());
        Collections.sort(this.listPersons, comp);
    }

    public void display()
    {
        for(Person p : this.listPersons)
        {
            System.out.println(p);
        }
    }

    /** Getters and Setters **/
}

Now we try this :

import java.util.ArrayList;

You might try to use hyperlink as the parent, and then change the inner elements on hover. Like this:

a.active h1 {color:red;}

a.active:hover h1 {color:green;}

a.active h2 {color:blue;}

a.active:hover h1 {color:yellow;}

This way you can change the style in multiple inner tags, based on the rollover of the parent element.

An alternative way to accomplish what you are asking, without having problems on the mobile version of your website, (Remember that the margin attribute will brake your responsive layout on mobile version thus you have to add on your element a supplementary attribute like @media (min-width:768px){ 'your-class'{margin:0}} to override the previous margin)

is to nest your class in your preferred div and then add on your class the margin option you want

like the following example: HTML

<div class="container">
  <div class="col-md-3 col-xs-12">
   <div class="events">
     <img src="..."  class="img-responsive" alt="...."/>
     <div class="figcaption">
       <h2>Event Title</h2>
       <p>Event Description.</p>
     </div>
   </div>
  </div>
  <div class="col-md-3 col-xs-12">
   <div class="events">
    <img src="..."  class="img-responsive" alt="...."/>
    <div class="figcaption">
     <h2>Event Title</h2>
     <p>Event Description. </p>
    </div>
   </div>
  </div>
  <div class="col-md-3 col-xs-12">
   <div class="events">
    <img src="..."  class="img-responsive" alt="...."/>
    <div class="figcaption">
     <h2>Event Title</h2>
     <p>Event Description. </p>
    </div>
   </div>
  </div>
</div>

And on your CSS you just add the margin option on your class which in this example is "events" like:

.events{
margin: 20px 10px;
}

By this method you will have all the wanted space between your divs making sure you do not brake anything on your website's mobile and tablet versions.

there is a easy way: 1. using website's web.config 2. in "staticContent" section remove specific fileExtension and add mimeMap 3. add "clientCache"

<configuration>
  <system.webServer>
    <urlCompression doStaticCompression="true" doDynamicCompression="true" />
    <staticContent>
      <remove fileExtension=".ipa" />
      <remove fileExtension=".apk" />
      <mimeMap fileExtension=".ipa" mimeType="application/iphone" />
      <mimeMap fileExtension=".apk" mimeType="application/vnd.android.package-archive" />
      <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="777.00:00:00" />
    </staticContent>
  </system.webServer>
</configuration>

Strings are nullable in C# anyway because they are reference types. You can just use public string CMName { get; set; } and you'll be able to set it to null.

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

# -i (inplace)

LANG=C sed -i -E "s|[\d128-\d255]||g" /path/to/file(s)

The LANG=C part's role is to avoid a Invalid collation character error.

Based on Ivan's answer and Patrick's comment.

Now there is a shorter way with Java 8 using Map::merge.

myMap.merge(key, 1, Integer::sum)

What it does:

• if key do not exists, put 1 as value
• otherwise sum 1 to the value linked to key

More information here.

You don't need EXEC clause. Simply use

proc_name paramValue1, paramValue2

(and you need commas as Misnomer mentioned)

You can also use replaceAll(search, replaceWith) [MDN].

Then, make sure you have a string by wrapping one type of quotes by a different type:

 'a "b" c'.replaceAll('"', "'")
 // result: "a 'b' c"
    
 'a "b" c'.replaceAll(`"`, `'`)
 // result: "a 'b' c"

 // Using RegEx. You MUST use a global RegEx(Meaning it'll match all occurrences).
 'a "b" c'.replaceAll(/\"/g, "'")
 // result: "a 'b' c"

Important(!) if you choose regex:

when using a regexp you have to set the global ("g") flag; otherwise, it will throw a TypeError: "replaceAll must be called with a global RegExp".

Probably the best cross browser solution for pdf display on web pages is to use the Mozilla PDF.js project code, it can be run as a node.js service and used as follows

<iframe style="width:100%;height:500px" src="http://www.mysite.co.uk/libs/pdfjs/web/viewer.html?file="http://www.mysite.co.uk/mypdf.pdf"></iframe>

A tutorial on how to use pdf.js can be found at this ejectamenta blog article

a simple way to do this, works on any page, requires HTML 5

// get the string following the ?
var query = window.location.search.substring(1)

// is there anything there ?
if(query.length) {
   // are the new history methods available ?
   if(window.history != undefined && window.history.pushState != undefined) {
        // if pushstate exists, add a new state to the history, this changes the url without reloading the page

        window.history.pushState({}, document.title, window.location.pathname);
   }
}

here you go Sir :-)

.myElement{
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    text-rendering: optimizeLegibility;
}

2

.myElement{
    text-shadow: rgba(0,0,0,.01) 0 0 1px;
}

Use the following:

var enteredText = document.getElementById("textArea").value;
var numberOfLineBreaks = (enteredText.match(/\n/g)||[]).length;
alert('Number of breaks: ' + numberOfLineBreaks);

DEMO

Now what I did was to split the string first using linebreaks, and then split it again like you did before. Note: you can also use jQuery combined with regex for this:

var splitted = $('#textArea').val().split("\n");           // will split on line breaks

Hope that helps you out!

Instead of subclassing ThreadPoolExecutor, I would provide it with a ThreadFactory instance that creates new Threads and provides them with an UncaughtExceptionHandler

Go online before starting android studio. Then go file->New project Follow onscreen steps. Then wait It will download the necessary files over internet. And that should fix it.

An approximated solution (based on an equirectangular projection), much faster (it requires only 1 trig and 1 square root).

This approximation is relevant if your points are not too far apart. It will always over-estimate compared to the real haversine distance. For example it will add no more than 0.05382 % to the real distance if the delta latitude or longitude between your two points does not exceed 4 decimal degrees.

The standard formula (Haversine) is the exact one (that is, it works for any couple of longitude/latitude on earth) but is much slower as it needs 7 trigonometric and 2 square roots. If your couple of points are not too far apart, and absolute precision is not paramount, you can use this approximate version (Equirectangular), which is much faster as it uses only one trigonometric and one square root.

// Approximate Equirectangular -- works if (lat1,lon1) ~ (lat2,lon2)
int R = 6371; // km
double x = (lon2 - lon1) * Math.cos((lat1 + lat2) / 2);
double y = (lat2 - lat1);
double distance = Math.sqrt(x * x + y * y) * R;

You can optimize this further by either:

1. Removing the square root if you simply compare the distance to another (in that case compare both squared distance);
2. Factoring-out the cosine if you compute the distance from one master point to many others (in that case you do the equirectangular projection centered on the master point, so you can compute the cosine once for all comparisons).

For more info see: http://www.movable-type.co.uk/scripts/latlong.html

There is a nice reference implementation of the Haversine formula in several languages at: http://www.codecodex.com/wiki/Calculate_Distance_Between_Two_Points_on_a_Globe

Have you tried using Timestamp.valueOf(String)? It looks like it should do almost exactly what you want - you just need to change the separator between your date and time to a space, and the ones between hours and minutes, and minutes and hours, to colons:

import java.sql.*;

public class Test {
    public static void main(String[] args) {
        String text = "2011-10-02 18:48:05.123456";
        Timestamp ts = Timestamp.valueOf(text);
        System.out.println(ts.getNanos());
    }
}

Assuming you've already validated the string length, this will convert to the right format:

static String convertSeparators(String input) {
    char[] chars = input.toCharArray();
    chars[10] = ' ';
    chars[13] = ':';
    chars[16] = ':';
    return new String(chars);
}

Alternatively, parse down to milliseconds by taking a substring and using Joda Time or SimpleDateFormat (I vastly prefer Joda Time, but your mileage may vary). Then take the remainder of the string as another string and parse it with Integer.parseInt. You can then combine the values pretty easily:

Date date = parseDateFromFirstPart();
int micros = parseJustLastThreeDigits();

Timestamp ts = new Timestamp(date.getTime());
ts.setNanos(ts.getNanos() + micros * 1000);

One can ask with some Java code:

System.out.println("Max memory: " + maxBytes / 1024 / 1024 + "M");

See javadoc.

There are 2 errors: the second is because $dom is no string but an object and thus cannot be "echoed". The first error is a warning from loadHTML, caused by invalid syntax of the html document to load (probably an & (ampersand) used as parameter separator and not masked as entity with &).

You ignore and supress this error message (not the error, just the message!) by calling the function with the error control operator "@" (http://www.php.net/manual/en/language.operators.errorcontrol.php )

@$dom->loadHTML($html);

If you're changing the layout of an existing ImageView, you should be able to simply get the current LayoutParams, change the width/height, and set it back:

android.view.ViewGroup.LayoutParams layoutParams = myImageView.getLayoutParams();
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams(layoutParams);

I don't know if that's your goal, but if it is, this is probably the easiest solution.

Use the observer pattern. It works like this:

interface MyListener{
    void somethingHappened();
}

public class MyForm implements MyListener{
    MyClass myClass;
    public MyForm(){
        this.myClass = new MyClass();
        myClass.addListener(this);
    }
    public void somethingHappened(){
       System.out.println("Called me!");
    }
}
public class MyClass{
    private List<MyListener> listeners = new ArrayList<MyListener>();

    public void addListener(MyListener listener) {
        listeners.add(listener);
    }
    void notifySomethingHappened(){
        for(MyListener listener : listeners){
            listener.somethingHappened();
        }
    }
}

You create an interface which has one or more methods to be called when some event happens. Then, any class which needs to be notified when events occur implements this interface.

This allows more flexibility, as the producer is only aware of the listener interface, not a particular implementation of the listener interface.

In my example:

MyClass is the producer here as its notifying a list of listeners.

MyListener is the interface.

MyForm is interested in when somethingHappened, so it is implementing MyListener and registering itself with MyClass. Now MyClass can inform MyForm about events without directly referencing MyForm. This is the strength of the observer pattern, it reduces dependency and increases reusability.

This command will remove the initial "CHEESE_" string from all the files in the current directory, using renamer:

$ renamer --find "/^CHEESE_/" *

1- you need to close the block of the function with '}', which is missing.

2- the argument of querySelector may not be an empty string '' or ' '... Use '*' for all.

3- those arguments will return the needed value:

querySelector('*')

querySelector('input')

querySelector('input[name="pwd"]')

querySelector('[name="pwd"]')

I had to struggle for a little bit but I found a solution, I added

-Dsonar.coverage.exclusions=**/*.* 

and the coverage metric was cancelled from the dashboard at all, so I realized that the problem was the path I was passing, not the property. In my case the path to exclude was java/org/acme/exceptions, so I used :

`-Dsonar.coverage.exclusions=**/exceptions/**/*.*` 

and it worked, but since I don't have sub-folders it also works with

-Dsonar.coverage.exclusions=**/exceptions/*.*

while it might not matter now here is a function which generate a float between 2 values.

#include <math.h>

float func_Uniform(float left, float right) {
    float randomNumber = sin(rand() * rand());
    return left + (right - left) * fabs(randomNumber);
}

I know it doesn't explain the meaning but I've made myself a little image, as reference to remind which one to use:

Hope it helps!

PS - Give a check also to the link in Nitay's answer

An AnyCPU assembly will JIT to 64-bit code when loaded into a 64-bit process and 32 bit when loaded into a 32-bit process.

By limiting the CPU you would be saying: There is something being used by the assembly (something likely unmanaged) that requires 32 bits or 64 bits.

All the answers posed in to this question are based on a mouse click event. You can also assign a ContenxtMenuStrip to your DataGridview and check if there is a row selected when the user RightMouseButtons on the DataGridView and decide whether you want to view the ContenxtMenuStrip or not. You can do so by setting the CancelEventArgs.Cancel value in the the Opening event of the ContextMenuStrip

    private void MyContextMenuStrip_Opening(object sender, CancelEventArgs e)
    {
        //Only show ContextMenuStrip when there is 1 row selected.
        if (MyDataGridView.SelectedRows.Count != 1) e.Cancel = true;
    }

But if you have several context menu strips, with each containing different options, depending on the selection, I would go for a mouse-click-approach myself as well.

I stumbled in here looking for a similar answer without the "git log" restriction. The answers here didn't give me what I needed but this did so I'll add it in case others find it useful:

git diff --name-only

You can also couple this with standard commit pointers to see what has changed since a particular commit:

git diff --name-only HEAD~3
git diff --name-only develop
git diff --name-only 5890e37..ebbf4c0

This succinctly provides file names only which is great for scripting. For example:

git diff --name-only develop | while read changed_file; do echo "This changed from the develop version: $changed_file"; done

#OR

git diff --name-only develop | xargs tar cvf changes.tar

You could use this one line change: Arrays.asList(set.toArray(new Object[set.size()]))

Map<String, List> mainMap = new HashMap<String, List>();

for(int i=0; i<something.size(); i++){
  Set set = getSet(...); 
  mainMap.put(differentKeyName, Arrays.asList(set.toArray(new Object[set.size()])));
}  

You could use .find("is"), it would return position of "is" in the string

or use .start() from re

>>> re.search("is", String).start()
2

Actually its match "is" from "This"

If you need to match per word, you should use \b before and after "is", \b is the word boundary.

>>> re.search(r"\bis\b", String).start()
5

I am gonna write what iv done very briefly (to delete any CocoaPods from my project)..

1. delete any added folder (frameworks, Pods,...)
2. delete any added files (PROJECT.xcworkspace, PodFile, PodFile.lock, Pods-PROJECT.debug.xcconfig, Pods-PROJECT.release.xcconfig,...)
3. just leave your original ones (PROJECT, PROJECT_Tests, PROJECT.xcodeproj)
4. remove framework reference from the project on xcode

To remove the framework reference from xcode:

1. Use the Project Navigator
2. Select Project
3. Select Target PROJECT
4. Select Build Phases from the top options
5. leave the default groups (Target Dependencies, Compile Sources, Linked Binary with Libraries, Copy Bundle Resources) and delete any other

First of all this is JavaScript and not C#

Then you cannot disable a div because it normally has no functionality. To disable a click event, you simply have to remove the event from the dom object. (bind and unbind)...

You can easily redirect different parts of your shell script to a file (or several files) using sub-shells:

{
  command1
  command2
  command3
  command4
} > file1
{
  command5
  command6
  command7
  command8
} > file2

In HTML:

<input type="submit" id="btnSubmit" name="btnSubmit" value="Save Changes" />
<input type="submit" id="btnDelete" name="btnDelete" value="Delete" />

In PHP:

if (isset($_POST["btnSubmit"])){
  // "Save Changes" clicked
} else if (isset($_POST["btnDelete"])){
  // "Delete" clicked
}

Add .* to s in your first line.

Try:

DELETE s.* FROM spawnlist s
INNER JOIN npc n ON s.npc_templateid = n.idTemplate
WHERE (n.type = "monster");

@JigarJoshi it's the good answer, and of course also @Tim recommendation to use .joda-time.

I only want to add more possibilities to subtract days from a java.util.Date.

Apache-commons

One possibility is to use apache-commons-lang. You can do it using DateUtils as follows:

Date dateBefore30Days = DateUtils.addDays(new Date(),-30);

Of course add the commons-lang dependency to do only date subtract it's probably not a good options, however if you're already using commons-lang it's a good choice. There is also convenient methods to addYears,addMonths,addWeeks and so on, take a look at the api here.

Java 8

Another possibility is to take advantage of new LocalDate from Java 8 using minusDays(long days) method:

LocalDate dateBefore30Days = LocalDate.now(ZoneId.of("Europe/Paris")).minusDays(30);

you can achieve it by creating two separate activity. Suppose first activity is halfScreen activity. In this activity your video view having small size. On button click of full screen video start another activity 'fullScreen activity'. In second activity the video view should be match parent to the parent layout.you can also start video in full screen from where it is paused in half screen.In my code i have implemented that.Also you can resume the video in half screen on the back press of fullscreen activity. This is work for me.Hope it will work for you also.

If you want to set a date, DateTimePicker.Value is a DateTime object.

DateTimePicker.Value = new DateTime(2012,05,28);

This is the constructor of DateTime:

new DateTime(int year,int month,int date);

Make sure you are using this org.json: https://mvnrepository.com/artifact/org.json/json

if you are using Java 8 then you can use

import org.json.JSONArray;
import org.json.JSONObject;

JSONArray array = ...;

array.forEach(item -> {
    JSONObject obj = (JSONObject) item;
    parse(obj);
});

Just added a simple test to prove that it works:

Add the following dependency into your pom.xml file (To prove that it works, I have used the old jar which was there when I have posted this answer)

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20160810</version>
</dependency>

And the simple test code snippet will be:

import org.json.JSONArray;
import org.json.JSONObject;

public class Test {
    public static void main(String args[]) {
        JSONArray array = new JSONArray();

        JSONObject object = new JSONObject();
        object.put("key1", "value1");

        array.put(object);

        array.forEach(item -> {
            System.out.println(item.toString());
        });
    }
}

output:

{"key1":"value1"}

use parseInt and compare like below:

javascript:alert(parseInt("2")>parseInt("10"))

For maintainability, I would attach the "blocking" handler on the element itself (in your case, the canvas).

theCanvas.onkeydown = function (e) {
    if (e.key === 'ArrowUp' || e.key === 'ArrowDown') {
        e.view.event.preventDefault();
    }
}

Why not simply do window.event.preventDefault()? MDN states:

window.event is a proprietary Microsoft Internet Explorer property which is only available while a DOM event handler is being called. Its value is the Event object currently being handled.

You can turn on syntax highlighting based on the contents of the file.

For example, my Makefiles regardless of their extension the first line as follows:

#-*-Makefile-*- vim:syntax=make

This is typical practice for other editors such as vim.

However, for this to work you need to modify the Makefile.tmLanguage file.

1. Find the file (for Sublime Text 3 in Ubuntu) at:

   /opt/sublime_text/Packages/Makefile.sublime-package
   

Note, that is really a zip file. Copy it, rename with .zip at the end, and extract the Makefile.tmLanguage file from it.

2. Edit the new Makefile.tmLanguage by adding the "firstLineMatch" key and string after the "fileTypes" section. In the example below, the last two lines are new (should be added by you). The <string> section holds the regular expression, that will enable syntax highlighting for the files that match the first line. This expression recognizes two patterns: "-*-Makefile-*-" and "vim:syntax=make".

   ...
   <key>fileTypes</key>
   <array>
       <string>GNUmakefile</string>
       <string>makefile</string>
       <string>Makefile</string>
       <string>OCamlMakefile</string>
       <string>make</string>
   </array>
   
   <key>firstLineMatch</key>
   <string>^#\s*-\*-Makefile-\*-|^#.*\s*vim:syntax=make</string>
   

3. Place the modified Makefile.tmLanguage in the User settings directory:

   ~/.config/sublime-text-3/Packages/User/Makefile.tmLanguage
   

All the files matching the first line rule should turn the syntax highlighting on when opened.

From New-style and classic classes:

Up to Python 2.1, old-style classes were the only flavour available to the user.

The concept of (old-style) class is unrelated to the concept of type: if x is an instance of an old-style class, then x.__class__ designates the class of x, but type(x) is always <type 'instance'>.

This reflects the fact that all old-style instances, independently of their class, are implemented with a single built-in type, called instance.

New-style classes were introduced in Python 2.2 to unify the concepts of class and type. A new-style class is simply a user-defined type, no more, no less.

If x is an instance of a new-style class, then type(x) is typically the same as x.__class__ (although this is not guaranteed – a new-style class instance is permitted to override the value returned for x.__class__).

The major motivation for introducing new-style classes is to provide a unified object model with a full meta-model.

It also has a number of immediate benefits, like the ability to subclass most built-in types, or the introduction of "descriptors", which enable computed properties.

For compatibility reasons, classes are still old-style by default.

New-style classes are created by specifying another new-style class (i.e. a type) as a parent class, or the "top-level type" object if no other parent is needed.

The behaviour of new-style classes differs from that of old-style classes in a number of important details in addition to what type returns.

Some of these changes are fundamental to the new object model, like the way special methods are invoked. Others are "fixes" that could not be implemented before for compatibility concerns, like the method resolution order in case of multiple inheritance.

Python 3 only has new-style classes.

No matter if you subclass from object or not, classes are new-style in Python 3.

None, actually. The String class is mutable.

unsafe
{
    string foo = string.Copy("I am immutable.");
    fixed (char* pChar = foo)
    {
        char* pFoo = pChar;

        pFoo[5] = ' ';
        pFoo[6] = ' ';
    }

    Console.WriteLine(foo); // "I am   mutable."
}

This kind of logic is done all the time in the String and StringBuilder classes, actually. They just allocate a new string each time you call Concat, Substring, etc. and use pointer arithmetic to copy over to the new string. Strings just don't mutate themselves, hence why they are considered "immutable".

By the way, do not attempt this with string literals or you will badly mess up your program:

string bar = "I am a string.";

fixed (char* pChar = bar)
{
    char* pBar = pChar;

    pBar[2] = ' ';
}

string baz = "I am a string.";

Console.WriteLine(baz); // "I  m a string."

This is because string literals are interned in the desktop .NET Framework; in other words, bar and baz point to the exact same string, so mutating one will mutate the other. This is all fine and dandy though if you're using an unmanaged platform like WinRT, which lacks string interning.

What you see for OPTIONS request is fine. Authorisation headers are not exposed in it.

But in order for basic auth to work you need to add: withCredentials = true; to your var config.

From the AngularJS $http documentation:

withCredentials - {boolean} - whether to to set the withCredentials flag on the XHR object. See requests with credentials for more information.

setting aria-hidden to false and toggling it on element.show() worked for me.

e.g

<span aria-hidden="true">aria text</span>

$(span).attr('aria-hidden', 'false');
$(span).show();

and when hiding back

$(span).attr('aria-hidden', 'true');
$(span).hide();

urllib went through some changes in Python3 and can now be imported from the parse submodule

>>> from urllib.parse import quote

The other day I found myself in a situation where %n would nicely solve my problem. Unlike my earlier answer, in this case, I cannot devise a good alternative.

I have a GUI control that displays some specified text. This control can display part of that text in bold (or in italics, or underlined, etc.), and I can specify which part by specifying starting and ending character indices.

In my case, I am generating the text to the control with snprintf, and I'd like one of the substitutions to be made bold. Finding the starting and ending indices to this substitution is non-trivial because:

• The string contains multiple substitutions, and one of the substitutions is arbitrary, user-specified text. This means that doing a textual search for the substitution I care about is potentially ambiguous.

• The format string might be localized, and it might use the $ POSIX extension for positional format specifiers. Therefore searching the original format string for the format specifiers themselves is non-trivial.

• The localization aspect also means that I cannot easily break up the format string into multiple calls to snprintf.

Therefore the most straightforward way to find the indices around a particular substitution would be to do:

char buf[256];
int start;
int end;

snprintf(buf, sizeof buf,
         "blah blah %s %f yada yada %n%s%n yakety yak",
         someUserSpecifiedString,
         someFloat,
         &start, boldString, &end);
control->set_text(buf);
control->set_bold(start, end);

My .replace()function using the patterns described on the other answers did not work. The pattern that worked for my case was:

var str = "Test\n\n\Test\n\Test";
str.replace(/\r\n|\r|\n/g,'
');

// str: "Test

Test
Test"

Try the require_all gem:

1. http://github.com/jarmo/require_all
2. https://rubygems.org/gems/require_all

It lets you simply:

require_all 'path/to/directory'

This issue can occur when there is a .git directory underneath one of the subdirectories. To fix it, check if there are other .git directories there, and remove them and try again.

Just to add, in django, if you have a query like:

MyModel.objects.all()

do:

MyModel.objects.all().query.sql_with_params()

or:

str(MyModel.objects.all().query)

to get the sql string

Jonas's answer does not change the font size of the axes. Sergeyf's answer does not work when there are multiple subplots.

Here is a modification of their answers that works for me when I have multiple subplots:

set(findall(gcf,'type','axes'),'fontsize',30)
set(findall(gcf,'type','text'),'fontSize',30) 

I realize this is a very old question, but if I landed here, so will others. So I figured I weigh in.

If you want the tooltip to be responsive to one line only regardless of how much content you add to it, the width has to be flexible. However, Bootstrap does initiate the tooltip to a width, so you have to at least declare what that width will be and make it flexible from that size on up. This is what I recommend:

.tooltip-inner {
    min-width: 100px;
    max-width: 100%; 
}

The min-width declares a starting size. As opposed to the max-width, as some other would suggest, which it declares a stopping width. According to your question, you shouldn't declare a final width or your tooltip content will eventually wrap at that point. Instead, you use an infinite width or flexible width. max-width: 100%; will ensure that once the tooltip has initiated at 100px wide, it will grow and adjust to your content regardless of the amount of content you have in it.

KEEP IN MIND Tooltips are not intended to carry a lot of content. It could look funky if you had a long string across the entire screen. And it will definitely will have an impact in your responsive views, specially smartphone (320px width).

I would recommend two solutions to perfect this:

1. Keep your tooltip content to a minimum so as to not exceed 320px wide. And even if you do this you must remember if you have the tooltip placed at the right of the screen and with data-placement:right, your tooltip content will not be visible in smartphones (hence why bootstrap initially designed them to be responsive to its content and allow it to wrap)
2. If you are hellbent on using this one line tooltip concept, then cover your six by using a @media query to reset your tooltip to fit the smartphone view. Like this:

My demo HERE demonstrates the flexibility and responsiveness on the tooltips according to content size and device display size as well

@media (max-width: 320px) {
    .tooltip-inner {
         min-width: initial;
         width: 320px;
    }
}

I suppese you alredy managed to solve it, but if someone is looking for similar solution then this worked for me:

 g.append('svg:text')
  .attr('x', 0)
  .attr('y', 30)
  .attr('class', 'id')
  .append('svg:tspan')
  .attr('x', 0)
  .attr('dy', 5)
  .text(function(d) { return d.name; })
  .append('svg:tspan')
  .attr('x', 0)
  .attr('dy', 20)
  .text(function(d) { return d.sname; })
  .append('svg:tspan')
  .attr('x', 0)
  .attr('dy', 20)
  .text(function(d) { return d.idcode; })

There are 3 lines separated with linebreak.

Warning: this way is not a safe way, but is very easy to use. Use it wisely.

Use the eval function.

print eval('2 + 4')

Output:

6

You can even use variables or regular python code.

a = 5
print eval('a + 4')

Output:

9

You also can get return values:

d = eval('4 + 5')
print d

Output:

9

Or call functions:

def add(a, b):
    return a + b

def subtract(a, b):
    return a - b

a = 20
b = 10    
print eval('add(a, b)')
print eval('subtract(a, b)')

Output:

30
10

In case you want to write a parser, maybe instead you can built a python code generator if that is easier and use eval to run the code. With eval you can execute any Python evalution.

Why eval is unsafe?

Since you can put literally anything in the eval, e.g. if the input argument is:

os.system(‘rm -rf /’)

It will remove all files on your system (at least on Linux/Unix). So only use eval when you trust the input.

When FIND returns #VALUE!, it is an error, not a string, so you can't compare FIND(...) with "#VALUE!", you need to check if FIND returns an error with ISERROR. Also FIND can work on multiple characters.

So a simplified and working version of your formula would be:

=IF(ISERROR(FIND("abc",A1))=FALSE, "Green", IF(ISERROR(FIND("xyz",A1))=FALSE, "Yellow", "Red"))

Or, to remove the double negations:

=IF(ISERROR(FIND("abc",A1)), IF(ISERROR(FIND("xyz",A1)), "Red", "Yellow"),"Green")

You can also use rowcount, but TOP is probably better and cleaner, hence the upvote for Mehrdad

SET ROWCOUNT 10
SELECT * FROM dbo.Orders
WHERE EmployeeID = 5
ORDER BY OrderDate

SET ROWCOUNT 0

The 1. usecase which comes into my mind, is an api call, which should't go into the render, because it will run for each state change. And the API call should be only performed on special state change, and not on every render.

changeSearchParams = (params) => {
  this.setState({ params }, this.performSearch)
} 

performSearch = () => {
  API.search(this.state.params, (result) => {
    this.setState({ result })
  });
}

Hence for any state change, an action can be performed in the render methods body.

Very bad practice, because the render-method should be pure, it means no actions, state changes, api calls, should be performed, just composite your view and return it. Actions should be performed on some events only. Render is not an event, but componentDidMount for example.

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

Define the variables at the beginning of the function so if there are no records, the variables exist and you won't get the error. Check for null values in the returned array.

$hn = null;
$pid = null;
$datereg = null;
$prefix = null;
$fname = null;
$lname = null;
$age = null;
$sex = null;

In case you want to apply common functions such as sum or mean, you should use rowSums or rowMeans since they're faster than apply(data, 1, sum) approach. Otherwise, stick with apply(data, 1, fun). You can pass additional arguments after FUN argument (as Dirk already suggested):

set.seed(1)
m <- matrix(round(runif(20, 1, 5)), ncol=4)
diag(m) <- NA
m
     [,1] [,2] [,3] [,4]
[1,]   NA    5    2    3
[2,]    2   NA    2    4
[3,]    3    4   NA    5
[4,]    5    4    3   NA
[5,]    2    1    4    4

Then you can do something like this:

apply(m, 1, quantile, probs=c(.25,.5, .75), na.rm=TRUE)
    [,1] [,2] [,3] [,4] [,5]
25%  2.5    2  3.5  3.5 1.75
50%  3.0    2  4.0  4.0 3.00
75%  4.0    3  4.5  4.5 4.00

Here is the "native" text tools way:

#!/bin/bash

string="abcd"
first=`echo $string|cut -c1|tr [a-z] [A-Z]`
second=`echo $string|cut -c2-`
echo $first$second

This is an Inequality operator.

Update

BlobBuilder has been obsoleted see how you go using it, if you're using it for testing purposes.

Otherwise apply the below with migration strategies of going to Blob, such as the answers to this question.

Use a Blob instead

As an alternative there is a Blob that you can use in place of File as it is what File interface derives from as per W3C spec:

interface File : Blob {
    readonly attribute DOMString name;
    readonly attribute Date lastModifiedDate;
};

The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.

Create the Blob

Using the BlobBuilder like this on an existing JavaScript method that takes a File to upload via XMLHttpRequest and supplying a Blob to it works fine like this:

var BlobBuilder = window.MozBlobBuilder || window.WebKitBlobBuilder;
var bb = new BlobBuilder();

var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://jsfiddle.net/img/logo.png', true);

xhr.responseType = 'arraybuffer';

bb.append(this.response); // Note: not xhr.responseText

//at this point you have the equivalent of: new File()
var blob = bb.getBlob('image/png');

/* more setup code */
xhr.send(blob);

Extended example

The rest of the sample is up on jsFiddle in a more complete fashion but will not successfully upload as I can't expose the upload logic in a long term fashion.

Here's another:

data[data$Code == "A" | data$Code == "B", ]

It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,

data[Code == "A" | Code == "B", ]

also works, which is one of the really useful things about R.

There are two problems with your code

1. To find an element by ID you must prefix it with a "#"
2. You are attempting to pass a Number to the find function when a String is required (passing "#" + 5 would fix this as it would convert the 5 to a "5" first)

Laravel 5 now supports changing a column; here's an example from the offical documentation:

Schema::table('users', function($table)
{
    $table->string('name', 50)->nullable()->change();
});

Source: http://laravel.com/docs/5.0/schema#changing-columns

Laravel 4 does not support modifying columns, so you'll need use another technique such as writing a raw SQL command. For example:

// getting Laravel App Instance
$app = app();

// getting laravel main version
$laravelVer = explode('.',$app::VERSION);

switch ($laravelVer[0]) {

    // Laravel 4
    case('4'):

        DB::statement('ALTER TABLE `pro_categories_langs` MODIFY `name` VARCHAR(100) NULL;');
        break;

    // Laravel 5, or Laravel 6
    default:                

        Schema::table('pro_categories_langs', function(Blueprint $t) {
            $t->string('name', 100)->nullable()->change();
        });               

}
